Plasma volume response patterns and a physiologic model of ultrafiltration in hemodialysis.

Ultrafiltration (UF) is an essential process of restoring fluid homeostasis during hemodialysis (HD). Fluid shifts across the extracellular compartments during UF, predominantly across the capillary interface and between the macro- and microcirculation. A mismatch between UF and transcapillary fluid transport can lead to hemodynamic instability leading to cardiac morbidity. We wished to study intradialytic fluid transport characteristics and their variation during UF to identify factors that govern variability in transcapillary fluid movement in HD. Twenty-two patients undergoing stable HD sessions were studied to measure and monitor absolute blood and plasma volume throughout UF. A computational mathematical model of predicted plasma volume decay during UF was analyzed with respect to the intradialytic real-time data profile. Pre- and post-dialysis fluid status was assessed using multifrequency bioimpedance spectroscopy. Serum electrolytes, osmolality, and total protein concentration were measured pre- and post-dialysis and during the intradialytic phase. Two distinct profiles of PV responses were detected. 60% of the patients presented plasma volume decline, characterized by a high percentage of volume decrease during the first hour, and a subsequent slower decrease with early rebound. The model was modified to achieve a proper fit of these volume profiles, assuming time-dependent changes in selected parameters governing the refilling flow. Although the modified model could more accurately fit the data, the new parameter values often fell outside of a physiologically acceptable range, suggesting that other factors not included in the classic description of transcapillary fluid transport might be the cause of the observed patterns.

Effect of Incorporating Soursop (Annona muricata) Leaves Powder on Reproductive Performance of Japanese Quail (Coturnix coturnix japonica)

Introduction: Soursop leaves are rich in various molecules, including total phenols, terpenes, and steroids, which possess a range of pharmacological properties that can be utilized in animal production to enhance both growth and reproduction of animals. The present study aimed to evaluate the effect of incorporating soursop (Annona muricata; A. muricata) leaves powder into feed on the reproductive performance of Japanese quail. Materials and methods: A total of 80 Japanese quails (64 females and 16 males) aged two weeks were randomly divided into four experimental groups, labeled T0, T1, T2, and T3, and received feed additives with 0 mg/kg body weight (bw), 250 mg/kg bw, 500 mg/kg bw, and 750 mg/kg bw of powdered soursop leaves, respectively. Additionally, water was provided ad libitum, and the quails' weights were measured every 7 days for a period of 75 days. At the end of the period, 12 female quails from each group were sacrificed after 24 hours fasting period. Blood was collected for hematological (Leukocyte, Erythrocyte, and Platelet indices) and serum biochemical (total serum cholesterol, total proteins, albumin, and globulin, Aspartate aminotransferase, Alanine aminotransferase, Urea, and Creatinine) analysis. The males were also sacrificed to evaluate the spermatozoa characteristics (mobility, concentration, and viability). Results: No statistical significant changes in growth characteristics or hematological parameters were observed. However, biochemical parameters increased significantly with the inclusion of Soursop (A. muricate) in quail feed, including increased total cholesterol, total protein, and globulin levels, and decreased malondialdehyde levels. This effect was most significant at dosage of 500 mg/kg bw. Serum levels of urea, Alanine aminotransferase, and Aspartate aminotransferase were not significantly affected by A. muricata whatever the concentration considered. A significant increase in fast progressive spermatozoa, along with a decrease in immotile spermatozoa, was observed with A. muricate at dosage of 500 mg/kg bw compared to the control. Sperm viability also increased significantly, particularly in live at dosage of 500 mg/kg bw. Significant increase was observed in fertility parameters, including increased fertility rate, hatchability rate of fertile eggs, total hatchability rate, and chick weight, along with decreased embryonic mortality at 500 mg/kg bw treatment compared to the control. Conclusion: In conclusion, the findings indicated that incorporating A. muricata leaf powder at 500 mg/kg bw into quail feed positively influences reproductive cells and boosts fertility growth promoters.

Effect of replacing Tifton 85 hay with Moringa hay (Moringa oleifera L.) on the nutrient metabolism, metabolic profile, and water balance of sheep.

This study aimed to evaluate the effect of replacing Tifton 85 hay (TH) with Moringa hay (MH) on the intake, apparent digestibility, ingestive behaviour, rumen parameters, serum attributes, nitrogen balance, water balance, and urinary attributes of sheep. Thus, 5 rams, ½ Dorper + ½ Santa Inês, that were 12 ± 4 months of age with an initial body weight of 32.8 ± 2.6kg were distributed in metabolic cages in a Latin square design. The experiment lasted 85 days and was divided into five 17-day periods. The animals received rations with increasing replacement (0, 100, 200, 300, or 400g/kg of dry matter in the total diet) of TH for MH. The forage: concentrate ratio of the diets was 40:60. Replacing TH with MH reduced (P < 0.05) the intake of organic matter, crude protein, neutral detergent fibre (NDFap), and total digestible nutrients by sheep. The apparent digestibility of NDFap and the feeding and rumination efficiencies of NDFap were reduced (P < 0.05) when MH replaced TH in the animals' diet. This replacement did not influence (P > 0.05) serum urea, total protein, creatinine, or aspartate aminotransferase in sheep. Replacing TH with MH decreased water intake and excretion (P < 0.05). In addition, nitrogen excretion via urine, urinary creatinine, and nitrogen absorption decreased (P < 0.05) when TH was replaced with MH. However, there was an increase in the sheep's nitrogen retention and urine pH. We recommend replacing 30% TH with MH in the diet of lambs because it does not compromise nutrient metabolism.

Dietary Chlorella vulgaris and Saccharomyces cerevisiae enhanced the growth performance, blood biomarkers, and antioxidative capacity of common carp (Cyprinus carpio)

Chlorella vulgaris (CV) has been investigated in aquaculture and shown as a potential functional feed additive. Therefore, this study tested the effects of dietary CV and Saccharomyces cerevisiae (SC) on the growth performance, blood biomarkers, and antioxidative capacity of common carp (Cyprinus carpio). Fish were allocated in four groups in triplicates, where each glass aquaria was stocked with 15 fish with 4.25±0.11 g/fish. Fish offered four test diets for 84 days: control (free from CV or/and SC), CV-supplemented diet (5 %), SC-supplemented diet (0.05 %; (10 × 109 CFU/g), and a mixture of CV and SC-supplemented diet (5 % CV+ 0.05 % SC), respectively. The results indicated that fish-fed CV or SC revealed enhanced growth performance (final weight, weight gain, and specific growth rate) and protein efficiency ratio, while the feed conversion ratio was reduced compared to the control. Fish-fed dietary SC or CV and SC mixture revealed higher villi length than the control. Besides, villi width and muscular thickness enhanced significantly in carps-fed CV and SC compared to the control. Fish-fed dietary CV and/or SC revealed lower moisture content and higher crude protein and total lipids than the control. The results indicated that fish-fed CV or SC revealed higher serum total protein than the control. On the other hand, the total cholesterol and triglyceride levels were markedly reduced in carps-fed dietary CV and/or SC compared to the control. The results indicated that fish-fed CV and/or SC revealed higher lysozyme activity, catalase, and glutathione peroxidase than the control. The superoxide dismutase of fish-fed CV or SC is higher than that of the control or CV and SC mixture. Additionally, the malondialdehyde levels (MDA) were markedly reduced in carp-fed dietary CV and/or SC compared to the control group. In conclusion, dietary C. vulgaris and/or S. cerevisiae can enhance growth performance and feed utilization in common carp. Besides, the biochemical blood markers and activated antioxidative capacity indicated that common carp fed C. vulgaris and/or S. cerevisiae revealed stable health status.

Dietary supplementation of distiller's grains yeast cultures improves performance and immunity by altering the intestinal flora of broilers.

Distiller's grains are a by-product of liquor production with a higher yield than liquor. Developing and utilizing distiller's grains well could alleviate the problem of scarce feed resources. Our present experiment was conducted with 6000 yellow-feathered broilers to study the effects of adding distiller's grains yeast cultures (DGYC) to the diet on growth performance and immunity of broilers. The broilers were divided into five groups, receiving different DGYC concentrations during two stages. Growth performance, intestinal microorganisms and immune organ development were measured. The results showed that groups B and D, supplemented with medium and high concentrations of DGYC, respectively, had significantly improved growth performance compared to the control group (P < 0.05). Group D also showed higher immune organ index (P < 0.01), increased serum total protein, high-density lipoprotein and immunoglobulin levels (P < 0.05) and lower levels of low-density lipoprotein, triglycerides, interleukin 1β and tumor necrosis factor α (P < 0.05). Hematoxylin and eosin staining confirmed improved immune organ development in group D (P < 0.05). Furthermore, in high-concentration group D, levels of short-chain fatty acids (SCFA; acetic, propionic and butyric acids) in cecal chyme were significantly increased (P < 0.05). The richness (Chao1) and diversity (Faith-pd) index of cecal microbiota were significantly higher in group D compared to the control group (P < 0.05). The microbial composition in group D differed from the control and medium-concentration group B. Seven bacteria (Clostridia-UCG-014, UCG-009, DTU089, UCG-010, Campylobacter, Harryflintia, Shuttleworthia) showed significant differences (P < 0.05). After DGYC feeding, DTU089 decreased, while other SCFA-producing bacteria increased (P < 0.05). Subsequently, KEGG function and corresponding signal pathway predictions were performed on bacteria with significant differences. Group D exhibited a higher enrichment of immune function pathways (P < 0.01) and showed significant changes in four immune signaling pathways according to the signal pathway heatmap. Our data suggest that high concentrations of DGYC can be applied as a feed additive for broilers that promotes growth, improves intestinal health and enhances certain immunity. © 2024 Society of Chemical Industry.

Comparative Analysis of the Potential Adaptability of Tibetan Dzo and Yellow Cattle Based on Blood Indices, Metabolites, and Fecal Microbiota.

This study aimed to investigate the differences in environmental adaptability between dzo and Tibetan yellow cattle by using corresponding assay kits to analyze blood indices, utilizing mass spectrometry for blood metabolite profiling, and performing 16S rDNA sequencing of fecal microbiota. Forty female cattle were randomly divided into a dzomo (female dzo) group (MG, n = 20) and a Tibetan-yellow-cattle group (HG, n = 20). After 150 days of uniform feeding, six cattle from each group were randomly picked for jugular blood sampling and collection of fecal microorganisms. The results showed that the serum albumin, creatinine, total protein, superoxide dismutase, IgG, and IgM concentrations in the MG group were higher (p < 0.05), whereas the serum triglyceride concentration was lower, compared to the HG group (p < 0.05). The higher level of phospholipids containing long-chain polyunsaturated fatty acids (PUFAs) (PC (18:5e/2:0), PC (20:5e/2:0), LPC 18:2, LPC 20:5) observed in the serum of the dzo suggests that they have an advantage in adapting to the challenging conditions of the plateau environment. The fecal microbiota analysis showed that Akkermansia was significantly enriched in the MG group; this might be the key bacterial genus leading to the strong adaptability of dzo. Our findings indicated the dzo's superior adaptation to the Tibetan Plateau's harsh environment.

Impact of Toxoplasma gondii on Serum Protein Levels and Mineral Content in Sheep and Goats at a Small Dairy Farm in White Nile State, Sudan

Aim: This study aims to investigate the effects of Toxoplasma gondii infection on the serum proteins and macro elements (Sodium, Potassium, Calcium, Magnesium and Phosphate) for sheep and goat. Introduction: In sheep and goats, Toxoplasma infection is a major cause of abortion and stillbirth. Subclinical infections are also quite common in adult animals of affected flocks and herds. Serum proteins and macro elements plays an essential role in animal metabolism. Materials and Methods: Serological survey of T. gondii was conducted using Latex Agglutination Test (LAT) for 20 sera collected from sheep and goats (8 and12 respectively) in white Nile State, Sudan. Results: Out of twelve goats’ serum and eight sheep serum samples, seven samples were found to be positive for Toxoplasma (58.33%) in goats and four samples were found to be positive for Toxoplasma (50%) in sheep, the remaining samples were negative. It was observed that serum Total protein (Tp) level was increased significantly (p&lt;0.05) in both species, and albumin (Alb) level decreased significantly (p&lt;0.05) in goats, while Globulin (Glob) was significantly (p&lt;0.05) low in sheep compared with control animals. The results showed that some minerals (Na and K) concentrations in the serum were higher in both sheep and goats compared to the controls. Conclusion: In conclusion infestation of goats with Toxoplama gondii increases the total protein, globulins and significantly decreases the albumin concentrations. For sheep the infestation increases the total protein, albumin and significantly decreases the globulin concentrations. Sheep and goats infected with Toxoplasma gondii showed increased serum sodium, potassium and magnesium levels affecting most of the enzyme systems.

Cellulose acetate electrophoretic separation of serum and urine proteins in Nigerian children with autism spectrum disorders

BackgroundAutism spectrum disorder (ASD) is a neurodevelopmental disorder (NDD) characterized by social communication challenges and restricted, repetitive behaviors. While genetic and environmental factors are known to contribute to ASD, the role of the immune system remains unclear. This study investigated the separation patterns of serum and urine proteins in Nigerian children with ASD compared to typically developing children and children with other NDDs.MethodsForty-seven participants aged 3–8 years were recruited, including 16 children diagnosed with ASD and 16 children with other NDDs, both according to DSM-5 criteria, along with 15 neurotypical children. Blood and urine samples were collected for protein analysis. Total protein and albumin levels were measured in both serum and urine using established methods. Protein separation in serum and urine was performed using cellulose acetate electrophoresis, followed by densitometry analysis of the electrophoretic patterns.ResultsThe results revealed no significant differences in total serum protein levels and most protein fractions between the groups. However, children with other NDDs exhibited significantly lower levels of alpha-2 globulin compared to neurotypical children. Conversely, both ASD and NDD groups showed significantly higher gamma globulin levels compared to the control group. Interestingly, spot urine protein levels were significantly higher in children with ASD compared to neurotypical children.ConclusionThe observed changes in alpha-2 and gamma globulin levels suggest potential immune system involvement in ASD and other NDDs. The higher urine protein excretion in the ASD group warrants further investigation to explore the potential of urinary protein biomarkers for ASD diagnosis.

Beta-caryophyllene attenuates experimental hepatocellular carcinoma through downregulation of oxidative stress and inflammation.

Hepatocellular carcinoma (HCC) is caused by various factors including toxic substances and xenobiotics. Numerous treatment strategies are used to address toxicity to the liver and HCC, yet their adverse effects are drawbacks. This study aimed to assess the effect of DEN/CCl4 on morphological changes in the liver, body weight, tumor incidence, and hematological tumor incidence, hematological parameters, hepatic markers, and histopathological analysis in mice following a preventive measure by using β-caryophyllene (BCP). Adult Balb/c mice were administered a single dose of DEN 1-mg/kg body weight and 0.2-mL CCl4/kg body weight intraperitoneal twice a week (i.p.) for 22 weeks. BCP was treated in one group of mice at 30-mg/kg body weight, intraperitoneal, for 7 weeks. BCP alone was treated in one group of mice at 300-mg/kg body weight intraperitoneal for 22 weeks. DEN/CCl4 caused a reduction in mice's body weight, which was significantly attenuated by BCP administration. BCP supplementation attenuated the tumor incidence DEN/CCl4 (100%) to about 25%. DEN/CCl4 caused alterations in the hematological parameters, serum total protein albumin globulin, A/G ratio, liver function markers (AST, ALT, ALP, GGT, ACP, and bilirubin), and lipid profile markers that were significantly reinstated by BCP administration. Oxidative stress markers (MDA, SOD, CAT, NO, LDH, and GST) were reduced by DEN/CCl4, which were significantly increased in BCP-treated groups. The liver histopathology alterations caused by DEN/CCl4 were amended considerably by BCP treatment. Immunohistochemical studies suggest that AFP, caspase-3, and COX-2 were chronically overexpressed in DEN/CCl4-exposed mice, notably attenuated by BCP administration. BCP suppressed tumor incidence by downregulating inflammation and inducing caspase-3-mediated apoptosis. Conclusively, BCP appears to be a potent natural supplement capable of repressing liver inflammation and carcinoma through the mitigation of oxidative stress and inflammation pathways.

111 Factors affecting transfer of passive immunity in beef calves

Abstract Data from 9 calving experiments were used to investigate relationships of dam, calf, and colostrum factors with passive transfer in beef calves. Serum was collected at 48.33 ± 1.25 (SD) h of age for 313 calves, and single rear quarter colostrum yields were determined pre-suckling for dams of 117 calves. Serum and colostrum IgG concentrations were determined by ELISA. Relationship of serum IgG with colostrum variables was determined using Pearson correlation coefficients. Serum IgG was positively correlated (P ≤ 0.002) with colostrum IgG (r = 0.47) and protein (r = 0.45) concentrations and colostrum total IgG (r = 0.28) but tended to be negatively correlated (r = -0.17, P = 0.06) with colostrum yield. Based on passive transfer thresholds in the literature, 3 calves (0.96%) had &amp;lt; 8 mg/mL serum IgG, 16 calves (5.1%) &amp;lt; 16 mg/mL, and 43 calves (13.7%) had &amp;lt; 24 mg/mL. For this analysis, calves with serum IgG &amp;lt; 24 mg/mL at 48 h were considered to have failure of passive transfer (FPT). Continuous variables (dam BW and calf size, 48-h serum chemistry panel, and time to stand) were compared for FPT versus non-FPT calves using a mixed model with FPT class (fixed effect) and experiment (random effect). Calves with FPT had less (P ≤ 0.03) circulating triglycerides, glucose, calcium, magnesium, total protein, globulin, and gamma-glutamyl transferase but greater (P ≤ 0.001) circulating non-esterified fatty acids, sodium, chloride, and total bilirubin than non-FPT. Effects of categorical variables on calf 48-h serum IgG were determined using separate mixed models with variable (fixed) and experiment (random). Primiparous dams gave birth to calves that had less (P = 0.05) serum IgG at 48 h than multiparous dams. Calves born to moderate dams (BCS = 5) had less (P = 0.007) serum IgG than those born to fleshy dams (BCS ≥ 6) and tended to have less (P = 0.08) serum IgG than calves born to thin dams (BCS &amp;lt; 5). Calf sex, calving season, calving difficulty score, and vigor score at 10 min did not affect (P ≥ 0.19) serum IgG. Relationships of calf 48-h serum IgG with continuous variables was also determined using Pearson correlation coefficients, and only r ≥ 0.20 or ≤ -0.20 are reported. Serum IgG was positively correlated (P ≤ 0.005) with 48-h serum total protein (r = 0.75), globulin (r = 0.76), gamma-glutamyl transferase (r = 0.32), and potassium (r = 0.20). Serum IgG was negatively correlated (P &amp;lt; 0.001) with gestation length (r = -0.22) and 48-h serum albumin (r = -0.43), sodium (r = -0.24), and total bilirubin (r = -0.27). Overall, beef calves in this dataset generally had successful passive transfer that was associated with several dam, calf, and colostrum factors.

A field study to optimize protein and lipid levels in diet for cage-cultured subadult rockfish Sebastes schlegelii

A feeding trial was conducted to evaluate growth, body composition, serum biochemistry, digestion and metabolism, and oxidation resistence of S. schlegelii fed 9 diets in a 3×3 factorial design (protein levels: 44 %, 48 %, 52 %; lipid levels: 6 %, 10 %, 14 %), to optimize protein and lipid levels for practical feed formula. Rockfish (114.25 g) were stocked into 27 cages in an offshore system and fed test diets to satiation twice daily for 8 weeks. Growth increased but feed conversion rate decreased with dietary protein increasing. Increasing dietary protein to >48 % led to reduced feeding intake but increased protein efficiency ratio. Lipid efficiency ratio increased with dietary protein increasing but decreased with dietary lipid increasing. Hepatosomatic index decreased coupling with the increases in condition factor and liver lipid content as dietary lipid increased to 14 %. Intraperitoneal fat ratio increased with dietary lipid increasing. Increasing dietary protein to > 48 % significantly elevated serum total protein and glucose concentrations, hepatic glycogen synthase activity. High-protein (52 %) diets elevated serum albumin and urea nitrogen concentrations, hepatic pyruvate kinase and alanine aminotransferase (ALT) activities but downregulated hepatic growth-hormone (GH) receptor. Activities of trypsin, lipase, serum superoxide dismutase and total antioxidant capacity decreased with the dietary lipid increasing. Increasing dietary lipid to > 10 % reduced serum GH concentration, and high-lipid (14 %) diets significantly enhanced serum triglyceride concentration and hepatic transaminases activities, and resulted in a visual increase of adipocytes in liver. Serum cholesterol and low-density lipoprotein decreased as dietary protein increased to 48–52 % or dietary lipid >10 %. Hepatic succinate dehydrogenase activity and serum IGF-1 significantly increased while hepatic fatty acid synthetase decreased as dietary protein increased to >48 % or dietary lipid >10 %. High-protein (52 %) diet or high-lipid (14 %) diet elevated serum malonaldehyde concentration. These findings suggested 48 % protein and 10 % lipid were the optimal in diet for subadult S. schlegelii.

Hepatic and immune modulatory effectiveness of lactoferrin loaded Selenium nanoparticles on bleomycin induced hepatic injury

This study aimed to estimate the hepatic and immune ameliorating potential of extracted bovine lactoferrin (LF), Selenium nanoparticles (SeNPs) or their combination (LF/SeNPs) against bleomycin (BLM) induced hepatic injury. Fifty adult male rats (160–200 g) were equally divided into five groups: (1) the saline control group, (2) BLM-injected (15 mg/kg twice a week, ip), and (3–5) groups treated orally with LF (200 mg/kg/day), SeNPs (0.0486 mg/kg/day) or LF/SeNPs combination (200.0486 mg/kg/day) for 6 weeks post BLM-intoxication. Blood and liver samples were subjected to biochemical, histopathological, and immunohistochemical analyses. The results revealed that BLM caused a significant increase in hepatic lipid peroxidation and nitric oxide, as well as serum markers of liver functions (AST, ALT and GGT activities), and levels of GM-CSF, CD4, TNF-α, IL-1β, TGF-β1, fibronectin, triglycerides, cholesterol and LDL-C. Additionally, hepatic glutathione, Na+/K+-ATPase, and glutathione peroxidase, as well as serum HDL-C, total protein and albumin levels were significantly reduced. Moreover, BLM injection resulted in marked histopathological alterations and severe expression of caspase 3. Post-treatment of BLM-intoxicated rats with LF, SeNPs or LF/SeNPs combination obviously improved the BLM-induced hepatic damages; this was achieved from the marked modulations in the mentioned parameters, besides improving the histopathological hepatic architecture. It is worth mentioning that LF/SeNPs exerted the greatest potency. In conclusion, the obtained results demonstrated that LF, SeNPs and LF/SeNPs succeeded in attenuating the BLM-induced hepatic dysfunction. Therefore, these supplements might be used to protect against drug-associated side effects.

Bioaccumulation of Deltamethrin and Piperonyl butoxide in Labeo rohita fish

Deltamethrin (DLM), in combination with the synergist piperonyl butoxide (PBO), is extensively used in pest control programs due to its potent pesticidal properties and appreciable safety margin. However, various research studies report their adverse effects on non-target organisms. In this study, we investigated the toxicity of DLM, PBO, and a DLM-PBO (3:1) combination on Labeo rohita (L. rohita) fish fingerlings. Fish behavior and mortality rates were recorded at different time intervals up to 96 h for concentrations of 0.003, 0.007, 0.015, 0.031, and 0.062 µg/mL, respectively. Biochemical, hematological, and histopathological studies were carried out. High-performance liquid chromatography (HPLC) was used to detect and quantify residues in fish samples. The LC50 values after 48 h for DLM, PBO, and DLM-PBO exposed fish fingerlings were found to be 0.028, 0.066, and 0.007 µg/mL, respectively. At a concentration of 0.003 µg/mL of DLM, PBO, and DLM-PBO, the treated fish fingerlings exhibited similar behavior to the control group. Hematological parameters, such as red blood cell (RBC) and white blood cell (WBC) counts, were reduced in the treated groups compared to the control. Biochemical parameters showed increased levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), while total serum protein levels decreased in DLM, PBO, and DLM-PBO treated fingerlings. Histopathological examination of liver, gill, and heart tissues revealed lesions with hydropic degeneration in the liver and fusions of gill lamellae in the treated tissues. Fish fingerlings exposed to the DLM-PBO combination appeared highly prone to toxicity compared to those treated with DLM and PBO separately.

Effect of goose-derived adiponectin peptide gADP3 on LPS-induced inflammatory injury in goose liver

ABSTRACT 1. This study evaluated the effects and mechanisms of action of the peptide gADP3 on hepatic inflammatory injury induced by lipopolysaccharide (LPS). 2. Hepatic inflammatory injury was induced in geese by intraperitoneal injection of LPS and gADP3, and the adiponectin receptor agonist AdipoRon (positive control) was used for potential amelioration. Serum inflammatory factor levels, liver function-related biochemical indicators and oxidative stress-related biochemical parameters in the liver tissues were determined. The expression levels of adiponectin and its receptors, inflammation and oxidative stress-related genes and key signalling molecules involved in adiponectin, inflammation and oxidative stress signalling pathways in liver tissues were detected. 3. The peptide gADP3 alleviated inflammatory cell infiltration and hepatic inflammatory changes, reversed the decrease in serum albumin (ALB), total protein (TP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) content or activity induced by LPS and increased the activity of the antioxidant enzymes CAT (catalase), SOD (superoxide dismutase) and GSH-Px (glutathione peroxidase). 4. The peptide gADP3 upregulated the expression of antioxidant enzyme-related genes GCLC, HO-1 and NQO1 in liver tissues, decreased the levels of inflammatory factors like TNF-α, IL-1β, IL-6, IFN-γ and TGF-β and reduced mRNA expression levels of inflammatory-related genes TNF-α, IL-1β, iNOS and TGF-β. Additionally, it increased the mRNA and protein expression levels of adiponectin and its receptors, as well as key molecules in the adiponectin signalling pathway like AMPK and PPARα. In addition, gADP3 reversed the changes in mRNA or protein expression of inflammatory and oxidative stress signalling pathway-related genes P38MAPK, NF-κBP65, TLR4 and Nrf2 in liver tissues caused by LPS treatment. 5. In conclusion, goose-derived adiponectin peptide gADP3, similar to the adiponectin receptor agonist AdipoRon, attenuated LPS-induced hepatic inflammatory injury in geese.

Plasma activated water effects on behavior, performance, carcass quality, biochemical changes, and histopathological alterations in quail

BackgroundPlasma-activated water (PAW) is an innovative promising technology which could be applied to improve poultry health. The current study investigated the effects of drinking water supply with PAW on quail behaviour, performance, biochemical parameters, carcass quality, intestinal microbial populations, and internal organs histopathology. A total of 54 twenty-one-day-old Japanese quail chicks were randomly allotted to three treatments provided with PAW at doses 0, 1 ml (PAW-1), and 2 ml (PAW-2) per one litter drinking water. Each treatment contained 6 replicates (3 birds/ cage; one male and two females).ResultsThe results clarified that there were no significant (P > 0.05) changes in behaviour, and performance. For the biochemical indicators, the PAW-1 group showed significantly higher serum H2O2, total protein and globulin levels compared with the other groups (P = 0.015, < 0.001, and 0.019; respectively). PAW groups had significantly lower serum creatinine and urea levels than the control (P = 0.003). For the carcass quality, the internal organs relative weight between different treatments was not changed. In contrast, there was a significant increase in the meat colour, taste, and overall acceptance scores in PAW groups compared with the control one (P = 0.013, 0.001, and < 0.001; respectively). For the intestinal microbial population, lactobacilli count was significantly higher in PAW-2 compared with the control group (P = 0.014), while there were no changes in the total bacterial count between different treatment groups. Moreover, mild histological changes were recorded in the intestine, liver, and spleen of PAW groups especially PAW-2 compared with the control one.ConclusionsPAW offered benefits, such as reducing creatine and urea levels, improving meat characteristics, and increasing lactobacilli count, all of which are crucial for sustainable quail farming. Therefore, further research is needed.

Impact of ultra-early enteral nutrition support on the prognosis of young and middle-aged postoperative patients with cerebral hemorrhage

To investigate the effect of ultra-early enteral nutrition (UEEN) support on the prognosis of young and middle-aged postoperative patients with cerebral hemorrhage. The clinical data of young and middle-aged patients (aged 18-59 years) admitted to Tianjin Fifth Central Hospital from January 2020 to June 2023 after surgery for intracerebral hemorrhage were retrospectively analyzed, and the general data, nutritional indexes, gastrointestinal complications, neurological function recovery and long-term prognosis of the patients were recorded. According to the time of initiation of enteral nutrition (EN) support, patients were divided into UEEN group (EN implementation within 12 hour after surgery) and early enteral nutrition (EEN) group (EN implementation within 24 to 48 hour after surgery). The differences of the above indexes between the two groups were analyzed and compared. A total of 64 young and middle-aged postoperative patients with cerebral hemorrhage were enrolled, including 32 cases in the UEEN group and 32 cases in the EEN group. There were no significant differences in gender, age, proportion of hypertension and diabetes, Glasgow coma score (GCS) on admission and surgical methods between the two groups. In terms of nutritional indexes, serum total protein, albumin and hemoglobin levels of patients in both groups on day 7 after admission were lower than those on day 1, and higher than those on day 3, and the above indexes levels in UEEN group were significantly higher than those in EEN group on day 7 [total protein (g/L): 63.05±5.79 vs. 59.02±6.63, albumin (g/L): 40.40±5.26 vs. 37.66±4.63, hemoglobin (g/L): 133.33±12.58 vs. 123.80±22.12, all P < 0.05]. In terms of gastrointestinal complications, the incidence of stress ulcer in the UEEN group within 14 days after admission was significantly lower than that in the EEN group [12.5% (4/32) vs. 31.3% (10/32), P < 0.05], but there was no statistically significant difference in feeding intolerance symptoms between the two groups. In terms of neurological recovery and long-term prognosis, GCS scores and Barthel index scores of 14 days after admission were higher than those of 1 day after admission, but there was no statistical significance between the two groups. Six months after surgery, Glasgow outcome scale (GOS) and Barthel index score of the UEEN group were significantly higher than those of the EEN group (GOS score: 3.81±1.06 vs. 3.18±1.07, Barthel index score: 60.78±7.24 vs. 54.52±5.13, both P < 0.05). UEEN support can improve the nutritional level of young and middle-aged postoperative patients with cerebral hemorrhage, reduce the occurrence of postoperative gastrointestinal complications, promote the recovery of neurological function, and improve the long-term prognosis.

Serum chemistry, thyroxine concentration, and blood cell morphology of wild, young Blackchin Guitarfish Glaucostegus cemiculus sampled on the eastern Mediterranean coastline.

The Blackchin Guitarfish Glaucostegus cemiculus is endemic to the Mediterranean Sea and is critically endangered, but relevant routine laboratory data are unavailable. Our objectives were to determine the packed cell volume (PCV), comprehensive serum chemistry analytes, and serum total thyroxine (sTT4) concentration; compare serum albumin and serum globulin concentrations as measured by two different methods; and describe the blood cell morphology of healthy, free-ranging Blackchin Guitarfish. Wild Blackchin Guitarfish were captured using a seine net. Blood samples for serum chemistry and hematological analyses were obtained and measured using routine laboratory methods. The fish were tagged and released. This study included 43 Blackchin Guitarfish (17 males and 26 females) that were younger than 6 months as estimated based on total length and body weight. The median PCV (n = 23) was 22% (minimum-maximum [min-max] = 15-25%). Median sTT4 (n = 10) measured by chemiluminescence immunoassay was 7.86 nmol/L (min-max = 7.52-9.57 nmol/L). The study included a comprehensive, 25-analyte serum chemistry analysis (e.g., serum iron and unbound and total iron-binding capacity) and a morphological description of all blood cells. Serum electrophoresis (SEP; n = 13) yielded a consistent serum albumin-migrating protein fraction and four globulin fractions. Serum electrophoretograms corroborating these results are presented. In Blackchin Guitarfish, the serum albumin-migrating fraction measured by SEP combined with serum total protein concentration yields a much higher albumin concentration compared to that measured by bromocresol green spectrophotometry. The true identity of this albumin-migrating fraction remains to be identified. The analytes' calculated 2.5-97.5% interpercentile intervals should be considered as reference intervals applying to Blackchin Guitarfish of similar age but should be applied cautiously to adult fish.

Neonatal lupus erythematosus presenting with effusions: A 13-year retrospective study.

Neonatal systemic lupus erythematosus (NLE) is an acquired autoimmune disease. The presence of effusions, such as pleural effusion and pericardial effusion, is rare. The present study helped investigate the clinical characteristics and progression of children with NLE combined with effusions. Clinical data of patients diagnosed with NLE were retrospectively collected and analyzed from January 1, 2011, to December 31, 2023, at the Children's Hospital of Soochow University and Suzhou Municipal Hospital. Patients with NLE were divided into effusion and non-effusion groups based on the presence of effusion. Moreover, the clinical data of the newborns in both groups were compared and investigated. Eleven (11/45, 24.44%) NLE patients had effusions, such as pleural effusion, testicular hydrocele, peritoneal effusion, pericardial effusion, and hydrocephalus. Other organs involved in effusion patients were cutaneous, gastrointestinal, hematologic, cardiac, and neurological. Among the patients with effusion, five cases of SLE in pregnant mothers, two cases of Sjogren's syndrome, one case of photoallergic symptoms, and three of pregnant mothers with no history of antenatal autoimmune disease. Pregnant mother' autoimmune disease in remission prior to pregnancy, or stable low disease activity. Seven patients were positive for Anti-SSA, five of which were double positive for Anti-SSA and Anti-SSB. Compared with the non-effusion group, the effusion group patients had significantly higher lactate dehydrogenase, creatine kinase, and fibrinogen, significantly lower platelets, total protein, and albumin. These patients were likelier to have thrombocytopenia and coagulation abnormalities. Logistics regression analysis demonstrated that NLE patients with effusions are more likely to have decreased serum total protein levels. All NLE patients with effusion have self-resorption of the effusion. 24.44% of patients had effusions in our study. NLE patients with effusion are more likely to have hematologic involvement and a more inflammatory response. The effusion in NLE patients is usually self-resorption, severe cases can be treated with nonsteroidal anti-inflammatory drugs/steroids. Key Points • NLE patients combined with effusions and were self-limiting, with pleural effusion being the most common. • NLE patients combined with effusions have a more inflammatory response, significant abnormalities in the blood routine and biochemical-related indexes.

322. IMPACT OF POSTOPERATIVE NUTRITIONAL SUPPORT MODES ON CLINICAL AND PATIENT-REPORTED OUTCOMES IN ENHANCED RECOVERY AFTER ESOPHAGECTOMY FOR CANCER

Abstract Background Enhanced Recovery After Surgery (ERAS) for esophagectomy has been demonstrated to be safe and effective. However, there is significant variation in the nutritional support treatment modes during the perioperative period. We have recently developed a novel ERAS nutritional support mode. In this study, we compared this new mode with the previous ERAS nutritional support treatment mode to assess their impact on clinical and Patient-Reported Outcomes (PROs), aiming to develop an optimal approach. Methods We enrolled 357 patients who underwent esophagectomy for esophageal thoracic cancer or esophagogastric junction cancer from June 2021 to August 2023. Two different ERAS nutritional support treatment protocols were used postoperatively: the control group previously received enteral nutrition by nasojejunal tube + parenteral nutrition + early oral diet after surgery, while the study group currently received parenteral nutrition + early oral diet. We compared the two groups in terms of clinical observation indicators, hematological analysis, serum protein changes and clinical outcomes. The comparison of quality of life on PROs was assessed using the MD Anderson Symptom Inventory. Symptom changes were analyzed using a mixed-effects model. Results A total of 324 patients successfully completed the ERAS nutritional support protocols. The success rates were 91% in the control group and 90.2% in the study group, with no statistically significant difference (p&amp;gt;0.05). The incidence of complications did not significantly differ between the two groups (p&amp;gt;0.05). Compared to the control group (n=223), the study group (n=101) significantly shortened the chest drain time (6.2±2.6 days vs. 6.6±1.5 days, p&amp;lt;0.05) and elevated the levels of serum total protein and albumin on the 4th postoperative day (53±5 g/L vs. 51±4 g/L, 30±2 g/L vs. 28±2 g/L, p&amp;lt;0.05). There were no statistically significant differences in the first flatus time, first defecation time, infusion time and postoperative hospital stay between the two groups (p&amp;gt;0.05). The comparison of hematological analysis, serum protein changes, changes in body weight during the perioperative period and 30-day readmission rate showed no statistically significant differences (p&amp;gt;0.05). In the MD Anderson Symptom Inventory, the study group had significantly better scores in sadness, dry mouth, enjoyment of life, and general activity dimensions compared to the control group (p=0.013, p&amp;lt;0.001, p=0.045, p=0.008). Conclusion Based on the similar rehabilitation outcomes, the simplified ERAS nutritional support treatment mode without postoperative enteral nutrition by nasojejunal tube is more optimized because it is physiological sound and significantly improves quality of life on PROs.

AMELIORATION OF LIVER AND KIDNEY FUNCTION PARAMETERS IN ALLOXAN-INDUCED DIABETIC RATS TREATED WITH 3-[2-(1,5-Dimethyl-3-oxo-2-Phenyl-2,3-Dihydro- 1H-Pyrazol-4-yl) Hydrazinylidene]-1-Phenylbutanedione, and its Ni(II) Complex.

This hydrazone: 3-[2-(1,5-Dimethyl-3-oxo-2-Phenyl-2,3-Dihydro-1H-Pyrazol-4-yl) Hydrazinylidene]-1-Phenylbutanedione (HL), and its Ni (II) Complex ([Ni(HL)2]Cl2) have been reported to possess hypoglycaemic property but the effects of their use on kidney and liver functions in diabetic animals have not been investigated. The study investigated some biochemical parameters in the liver and kidney of alloxan-induced diabetic rats treated with these hydrazone compounds. Diabetes was induced by a single intraperitoneal dose of alloxan (150 mg/kg). Data showed that these compounds induced a significant decrease in serum glucose levels in the diabetic rats. Diabetic rats were administered orally with compounds for fourteen days after which some biochemical indices in the serum, liver and kidney were measured and compared with the control. Serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, total protein and creatinine of untreated diabetic group was significantly elevated when compared with the normal control group. The ALP, AST concentrations of diabetic rats treated with low and high doses of HL was observed to be non-significantly (p &gt; 0.05) higher compared with rats in the normal control group A. A significantly (p &lt; 0.05) decrease in the ALT, AST and ALP concentrations of diabetic rats treated with 200 and 400 mg/kg b.w. of HL and [Ni(HL)2]Cl2 were observed when compared with untreated rats in group B. These results suggest that administration of these compounds to diabetic rats did not have any adverse effect on the liver and kidney functions in rats showing that the compounds are not toxic to man.
