Oxidative stress and type 2 diabetes: the development and the pathogenesis, Jordanian cross-sectional study

Accumulation of reactive oxygen species (ROS) can disrupt the antioxidant defense system, leading to oxidative stress that leads to pathological damage to vital human organs, including hormone-producing glands. Normal physiological function is subsequently disrupted and disorders such as Type 2 Diabetes Mellitus (T2DM) may develop. The critical role of the antioxidant defense system in counteracting ROS and mitigating oxidative stress is fundamental to understanding the pathogenesis of T2DM. In our study, we monitored the oxidant/antioxidant status in a selected Jordanian population to further elucidate this relationship. Our results show higher serum levels of Malondialdehyde (MDA); 0.230 ± 0.05 and 0.207 ± 0.06 μmol/l for the diabetic and the obese groups, respectively, relative to 0.135 ± 0.04 μmol/l for the non-obese healthy group. Lower activity of Catalase (CAT) was recorded among the diabetic (9.2 ± 3.2) and obese groups (11.0 ± 2.8), compared to the non-obese healthy group (12.1 ± 3.5). Significant elevations (P < 0.05) were observed in uric acid concentrations in diabetic and obese subjects: 451 ± 57 mg/dl and 430 ± 51, respectively, versus 342 ± 57 mg/dl in the non-obese healthy group. Moreover, no significant differences were obtained between all the studied groups for the serum albumin and total protein concentrations. Our findings demonstrate the potential role of oxidative stress in the development and occurrence of T2DM.

Evaluation of Infected and Non-infected Wounds Healing Activity of Eriosema robustum Hydroethanolic Leaves Extract Ointments in Streptozotocin Induced Diabetic Rats

Untreated diabetic wounds provide an optimal environment for bacterial growth, which, over time, can develop resistance to common antibiotics and ultimately result in amputation. Therefore, it is necessary to search for new sources of antimicrobial molecules with wound healing activity owing to the presence of different secondary metabolites in medicinal plants. Aims: This study was to evaluate the in vivo antibacterial and diabetic wound healing capabilities of 70° hydroethanolic extract of Eriosema robustum leaves on non-infected and infected diabetic wound. Methodology: To do this, obese albino Wistar male rats (200–280 g) were divided into eleven groups and were made diabetic by intraperitoneal injection with a low dose of streptozotocin at 45 mg/kg of body weight. An excision wound with a surface area of 314 mm2 was created on the dorsal area of each animal, except in the uninjured diabetic group (UDG). The 70° hydroethanolic extract was used to prepare 1%, 5%, and 10% ointments, with L-Mesitran serving as the reference ointment. Healing potential was assessed by measuring wound contraction rates and determining serum and tissue hydroxyproline, serum lactate deydrogenase (LDH) and total protein levels (TP). The antibacterial power evaluated in vivo of Eriosema robustum leaves was also assessed by culturing the skin after healing. Results: The results demonstrated a significantly faster healing rate in the non-infected groups (5%,10% and L-Mesitran) compared to the infected groups. The levels of tissue hydroxyproline and total proteins were significantly (p &lt; 0.05) elevated in all treated groups compared to infected and negative controls, unlike serum hydroxyproline levels. LDH levels were significantly (p &lt; 0.05) elevated in both negative control group compared to the treated groups. The culture of different skin samples on previously injured areas on the 20th day of treatment showed no growth of S. aureus on completely healed areas and a low rate in the groups treated during the healing process. Conclusion: 70° Hydroethanolic leaves extract of Eriosema robustum possess in vivoantibacterial activities and diabetic wound healing potential.

Effects of potassium diformate on growth performance, apparent digestibility of nutrients, serum biochemical indices, and intestinal microflora in Cherry Valley ducks

This study was performed to investigate the effects of potassium diformate (KDF) on growth performance, apparent digestibility of nutrients, serum biochemical indices, and intestinal microflora of Cherry Valley ducks. In total, 144 female healthy 1-day-old Cherry Valley ducks were divided into 3 groups with 6 replicates per group and 8 ducks per replicate according to the principle of similar body weight. The control group was fed a basic diet. In the 2 experimental groups, 0.8% and 1.2% KDF was added to the basic diet, respectively. The trial period was 6 wk and the pretrial period was 3 wk. The final weight and ADG were significantly higher in the 0.8% KDF group than in the control group (P < 0.05). The feed-to-gain ratio was significantly lower in both KDF groups than in the control group (P < 0.05). The apparent digestibility of CP was significantly higher in both KDF groups than in the control group (P < 0.05). The apparent digestibility of calcium was also significantly higher in the 0.8% KDF group (P < 0.05). The serum levels of alkaline phosphatase, cholesterol, and total protein were significantly lower in the 0.8% KDF group than in the control group (P < 0.05), the IgM content was significantly higher (P < 0.05), the low-density lipoprotein cholesterol, triglyceride, and urea levels were significantly lower (P < 0.01), and the glucose level was significantly higher (P < 0.01). The serum total protein level was significantly higher in the 1.2% KDF group than in the control group (P < 0.05). The relative abundance of Firmicutes and Patescibacteria in the gut of ducks was significantly higher in the 0.8% KDF group than in the control group (P < 0.05), the relative abundance of unclassified Erysipelotrichaceae and Lactobacillus was significantly higher (P < 0.01), and the relative abundance of Fusobacteriota was significantly lower (P < 0.05). However, the relative abundance of Firmicutes in the gut of ducks was significantly higher in the 1.2% KDF group than in the control group (P < 0.05). The relative abundance of unclassified Erysipelotrichaceae and Clostridium sensu stricto 1 was significantly higher (P < 0.01), as was the relative abundance of Fusobacteriota and Proteobacteria (P < 0.05). These findings indicate that the addition of 0.8% KDF to the diet can improve the growth performance of Cherry Valley ducks, promote the absorption of nutrients, change the structure of the microflora in the cecum, and increase the relative abundance of dominant bacteria. It was also shown that there was a significant difference between the 0.8% and 1.2% KDF levels which suggest that the safety margin for overdosing is quite low.

STUDY ON NORMAL HRMATOLOGICAL VALUES OF ARABIAN RACE HORSES

Hematological values for sixty clinically normal Arabian bred race horses of both sexes were estimated.Red cell ,count, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean ‘corpuscular hemoglobin concentration, white cell count, differential leukocytic count, total serum protein, albumin and globulin were determined by using several laboratory techniques. It appeared that the total serum protein and globulin were significantly higher in the stallions than those in mares (P &lt; 0.05) whereas the results of other hemaltological parameters were comparable and the mean values did not show significant differences (P &gt; 0.05).

Dietary biochar effect on growth performance, proximate composition, and physiological response of Penaeus vannamei (Boone, 1931) cultured in inland saline groundwater

Transforming raw materials (biomass feedstock) into biochar finds diverse applications across various industries owing to the distinctive characteristics of biochar. This study used biochar as a feed additive for shrimp feeding. A 90-day feeding trial was conducted to assess the impacts of different biochars on growth parameters, haematological parameters, and digestive enzymes of Penaeus vannamei reared in inland saline groundwater of 10 ppt salinity. The finely ground biochar (0.5 mm) prepared from different sources was mixed with the commercially available shrimp feed (35 % crude protein, 5 % crude fat, and 4 % crude fibre), viz., T1, paddy straw biochar (PSB); T2, sugarcane bagasse biochar (SBB); T3, banana peduncle biochar (BPB); and the control group (C) without any biochar. Twenty shrimp (10.24 ± 0.01 g) were stocked in each triplicate. Banana peduncle biochar incorporated diet (T3) demonstrated superior performance as it significantly (p<0.05) improved the weight gain (24.51±0.12 g), specific growth rate (1.39±0.00 % day−1), protein efficiency ratio (1.73±0.02 %), and reduced feed conversion ratio (1.60±0.01). The total serum protein in the haemolymph of the shrimps for all the dietary biochar treatments differed significantly (p<0.05) from the control. The T1, T2, and T3 groups showed the highest whole-body crude protein content; contrary to this, the lowest amount of whole-body crude protein was observed in the control. In addition, the dietary biochar significantly influenced the digestive enzymatic activity of shrimp. The hepatopancreatic AST and ALT activities of different biochar-fed groups were significantly (p < 0.05) higher than the C group. On the other hand, dietary biochar treatments did not significantly (p > 0.05) influence the SOD of the gill, muscle, and catalase activity of the hepatopancreas, gill, and muscle in shrimp. Overall, the three different dietary biochar supplementations in the diet of Penaeus vannamei seem to be an effective way to culture it intensively, in addition to significantly reducing various stress responses.

Assessing the impact of colostrum feeding delay on serum immunoglobulin G and total protein in dairy goat kids

This experiment was motivated by the need to understand the impacts of delaying the first colostrum feeding on the prevalence of failed transfer of passive immunity (FTPI). A cohort of 216 kids was stratified into groups based on the colostrum feeding delay postbirth: 0–4 h, 4–8 h, 8–12 h, and 12–16 h. All kids received a single colostrum meal of 300 mL, and blood samples were collected approximately 36 h after feeding. Serum immunoglobulin G (SIgG) was measured using ELISA, and serum total protein (STP) was assessed using the Bradford method and refractometry (STPb and STPr). Statistical methods like Pearson correlations, Bland-Altman plots, and Lin’s concordance coefficient were employed to assess associations and agreements between SIgG, STPb and STPr. Receiver operator characteristic analysis was employed to determine optimal STPb and STPr thresholds for predicting FTPI (SIgG < 12 g/L). Subsequently, areas under the curve, sensitivity, and specificity were examined to assess the accuracy of these thresholds. Our results showed that for each hour’s delay from birth to colostrum intake (up to 16 h), IgG apparent efficiency of absorption (AEA) decreases at an approximate rate of 2.0% per hour, and SIgG decreases at an approximate rate of 1.0 g/L per hour. However, this decline is not constant over time but intensifies progressively with increased feeding delay. Specifically, reductions in IgG AEA were 1.3, 2.9, and 5.9% per hour, and decreases in SIgG were 0.2, 0.3, and 0.7 g per hour for SIgG across the time intervals of 0–4 to 4–8 h, 4–8 to 8–12 h, and 8–12 to 12–16 h, respectively. Additionally, there was an increase in SIgG of 1.2 g/dL but a decrease in IgG AEA of 1.9% for each gram per kg of BW increase in IgG intake. The correlations between SIgG and STPr and STPb were 0.62, and 0.36, respectively. Optimal STPr and STPb thresholds predicting FTPI were determined to be 4.6 and 6.2 g/dL. The prevalence of FTPI, according to SIgG, STPr, and STPb thresholds were 63, 62, and 45%. Overall, STPr showed higher values for key performance metrics (i.e., sensitivity, likelihood ratio of positive tests, overall accuracy, and Youden’s index), indicating better prediction ability than STPb. Our findings corroborate the critical importance of swift colostrum administration, ideally occurring no later than 12 h postbirth. Moreover, our research validates the effectiveness of Brix refractometry as a practical, on-farm method for assessing FTPI in goat kids.

Protection against α-Amanitin-induced liver toxicity: Efficacy of pomegranate seed oil and black cumin oil

The consumption of mushrooms containing α-Amanitin (α-A) can lead to severe liver damage. In this study, toxicological experiments were conducted to confirm the protective effects of pomegranate seed oil (PSO) and black cumin oil (BCO) against α-A-induced hepatotoxicity. Rats exposed once to α-A (3 mg/kg bw, i.p.) or saline alone (0.1 ml, i.p.) were either left untreated or treated with PSO or BCO at a dose of 2 ml/kg bw/day by oral gavage on the same day, and the treatment was continued for 7 days. Serum aminotransferases (ALT and AST), alkaline phosphatase (ALP) and total protein levels were measured and the active caspase 3 (cl-caspase 3) was evaluated by western blotting in the liver. Serum ALT, AST and ALP levels tended to decrease in the α-A exposed group, but no statistically significant difference was found compared to the saline group (p > 0.05). PSO and BCO did not affect serum liver function tests in rats exposed to saline or α-A. α-A toxicity was demonstrated by a significant decrease in serum total protein level (p < 0.05), a significant increase in liver cl-caspase 3 expression (p < 0.05), and structural liver damage mainly characterized by mononuclear inflammation and steatosis. When α-A exposed rats were treated with BCO, the increase in cl-caspase 3 was not inhibited, on the contrary BCO increased cl-caspase 3 in healthy rats (p < 0.05). PSO significantly ameliorated α-A-induced cl-caspase 3 increase and inflammatory histopathology in the liver. Both PSO and BCO completely prevented α-A-induced protein degradation. The findings indicate that PSO and BCO may protect liver functions against α-A-induced hepatotoxicity, encouraging future comprehensive studies to test them at different doses and frequency.

A case of hyperviscosity syndrome associated with Waldenström macroglobulinemia treated with membrane plasma exchange without predilution.

A 75-year-old man with blurred vision and nasal bleeding was diagnosed with hyperviscosity syndrome and central retinal vein occlusion secondary to Waldenström macroglobulinemia. Serum total protein and IgM levels were undetectable. Because of the severe symptoms, we determined that immediate plasma-exchange treatment was required to decrease the blood viscosity. The initial plasma exchange was performed using the membrane isolation method with a predilution standby. A saline predilution replacement was prepared to decrease the total membrane pressure (TMP); however, the predilution protocol was not used because the planned treatment volume could be achieved without increasing the TMP. After two consecutive days of membrane plasma exchange, all serum biochemical tests were measurable, and IgM was below 4000mg/dL. After chemotherapy, his visual symptoms improved, and he was discharged. Since it is difficult to assess the risk of elevated TMP prior to initial plasma exchange, membrane plasma exchange with a predilution standby may be a useful strategy for initial plasma exchange for hyperviscosity syndrome in terms of safety and efficiency.

The Short-term Exposure Effect of Chlorpyrifos (20% EC) on Haematological, Biochemical and Histopathological Response of Striped Catfish Pangasianodon hypophthalmus

An experiment of acute toxicity was conducted to find out the lethal concentration 50 (LC50) of chloropyrifos (CPF) for Pangasianodon hypophthalmus. Our findings indicated that the 96-h LC50 value of CPF for P. hypophthalmus was 0.106 mg L-1. Effects of different concentrations of CPF (0.09, 0.1, 0.11, 0.12, and 0.13 mg L-1) for 96-h on hemato-biochemical, enzyme and histological effects were evaluated in this study. Acute exposure induced significant differences in enzymes acid phosphatase, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and acetylcholine of blood serum of the treated group as compared to control group. However, significant decreases in serum total protein, globulin, albumin, and triglycerides levels while serum glucose enhanced with consequent increasing doses of CPF exposure. Also, CPF induced significant declines in RBC count, haemoglobin and hematocrit level whereas the exposure groups showed significant rises in WBC and blood indices levels as compared to control group. Furthermore, CPF exposure causes gill curling, epithelium lifting, necrosis, and lamellae degeneration. Hemosiderin, sinusoid dilations, necrosis, malanomacrophage, hepatocyte hypertrophy were observed in liver histology. Reduction of lumen tubule, hyperplasia, increased bowman space and degenerations were seen in kidney. Overall findings indicates that the acute CPF exposure to P. hypophthalmus resulted in significant adverse changes in biochemical, hematological, and histopathological response.

Racial differences in serological markers across the first year of injury in spinal cord injury: a retrospective analysis of a multi-center interventional study

Study designSecondary analysis of a randomized, multi-center, placebo-controlled study(Sygen®).ObjectivesTo evaluate racial differences in serological markers in individuals with spinal cord injury(SCI) across the first year of injury.SettingHospitals in North America.MethodsSerological markers (e.g.,cell count, liver, kidney, and pancreatic function, metabolism, and muscle damage) were assessed among 316 participants (247 White, 69 Black) at admission, weeks 1, 2, 4, 8, and 52 post-injury. Linear mixed models were employed to explore the main effects of time, race (Black vs. White), and their interaction, with adjustment of covariates such as study center, polytrauma, injury (level, completeness), treatment group, and sex.ResultsA main effect of race was observed where White individuals had higher alanine transaminase, blood urea nitrogen(BUN), BUN/Creatinine ratio, sodium, and chloride, while Black individuals had higher calcium, total serum protein, and platelets. For markers with interaction effects, post-hoc comparisons showed that at week 52, White individuals had higher mature neutrophils, hematocrit, hemoglobin, mean corpuscular hemoglobin, albumin, and triglycerides, and Black individuals had higher amylase. Eosinophils, monocytes, red blood cells, aspartate aminotransferase, bilirubin, cholesterol, partial thromboplastin time, urine specific gravity, urine pH, CO2, and inorganic phosphorus did not differ between races.ConclusionsOur results revealed racial differences in serological markers and underscores the importance of considering race as a determinant of physiological responses. Future studies are warranted to explore the causes and implications of these racial disparities to facilitate tailored clinical management and social policy changes that can improve health equity.

Estimated breeding values of dairy sires for cow colostrum and transfer of passive immunity traits

The objective of this study was to derive the estimated breeding values (EBVs) of Holstein sires for colostrum and passive transfer of immunity traits to a) estimate the genetic association between these new traits and established production, conformation, and functional, and b) explore whether sires can be classified in specific profiles regarding the new traits. For cow colostrum traits, the study included 699 daughters of 67 sires from 6 commercial dairy herds. The number of daughters per sire ranged from 5 to 49. Passive transfer of immunity was measured as the blood serum total protein content in 854 purebred Holstein calves of 61 sires from 8 commercial dairy herds. The number of calves per sire ranged from 5 to 44. Data were statistically analyzed using mixed models. Approximate genetic correlations of the derived sire EBVs for cow colostrum and calf serum total protein with EBVs for several other traits were estimated. Moreover, sires were classified into colostrum and calf serum total protein profile groups. Approximate genetic correlations of cow colostrum and calf serum traits with milk production, conformation, and functional traits were mostly unfavorable. Colostrum total solids and protein contents were negatively correlated with milk yield, fat yield, protein yield, productive life, and livability. The only favorable correlation found was between colostrum total solids/calf serum total protein and daughter pregnancy rate. However, several bulls had favorable profiles in both colostrum/passive transfer of immunity and production traits. Colostrum/passive immunity traits could be included in future genetic improvement programs after careful structure of relevant indexes.

Physiological and Histological Effects of Flaxseed Oil on the Liver and Heart Muscle

Abstract Background: Flaxseeds are the focus of medical nutrition due to their potential benefits for human health. Flaxseed oil is rich in unsaturated fatty acids and has many biological effects. Objective: This study aimed to assess the effects of flaxseed oil on lipid profile, liver, and heart. Materials and Methods: One hundred mice were randomly divided into 10 groups: 10 mice for each group (either male or female). Ten males and 10 females served as control groups, group 1 received flaxseed oil orally (60 mg/kg body weight/day). Twenty of them (10 of each gender) were treated for 1 week and another 20 mice (10 of each gender) were treated for 2 weeks. In the same way, group 2 was divided and treated with 120 mg/kg/day. Measurements of serum lipid profile, serum lactate dehydrogenase, serum total protein, and albumin were performed along with histological examination of the liver and heart. Results: The comparative data showed that there were statistically significant decreases in total cholesterol, low-density lipoprotein (LDL), serum albumin, and total protein levels. There were also statistically significant increases in levels of very low-density lipoprotein (VLDL), triglycerides, high-density lipoprotein (HDL), and lactate dehydrogenase enzyme. Histological examination revealed striking histological changes in the liver and heart. Conclusion: Consumption of flaxseed oil reduced total cholesterol and LDL levels and increased the levels of VLDL, triglycerides, HDL, and lactate dehydrogenase enzyme. Flaxseed oil in high doses causes damage to the liver and heart muscle.

Clinical Characteristics and Outcomes of Neonatal Hepatoblastoma: A Single Center Study

ObjectiveHepatoblastoma (HB) diagnosed within one month following birth qualifies for a diagnosis of neonatal HB, whose prognosis is reportedly controversial, and its treatment is challenging. This study discussed the diagnosis, treatment, and outcomes of neonatal HB at a single center so as to enhance its overall management in the future. MethodsThe clinical information of babies diagnosed with neonatal HB at our center from August 2009 to September 2023 were retrospectively analyzed for demographics, clinical features, therapy, and outcomes. The outcomes were estimated by the Kaplan–Meier analysis method. ResultsThe study comprised 79 patients aged less than one year old, among which 14 had neonatal HB whereas 65 were non-neonatal HB patients. No differences were found between groups regarding gender, birth weight, delivery details, parental age, clinical signs, or treatment strategies. Neonatal HB patients were more likely to have PRETEXT I-II, smaller tumor size, congenital diseases, and lower risk tumor grade (p < 0.05). Additionally, the AFP levels of all neonatal HB patients were greater than 10,000 ng/ml (p = 0.009) and they had higher levels of ferritin (p = 0.003) and hemoglobin (p = 0.021), but lower levels of serum total proteins (p = 0.001). The three-year survival rate (100% vs 90.8%) and three-year event-free survival rate (100% vs 86.2%) in the neonatal HB group were higher than the non-neonatal HB group. ConclusionNeonatal HB patients have unique clinical features and can achieve an excellent prognosis following combined treatment with surgery and chemotherapy. Tumor resection, when carefully performed, was safe even in babies younger than one months old. Further and long-term studies are needed from a larger neonatal HB population.

Evaluation of portable refractometr as an alternative method to biuret assay for measurement of serum total protein in horse

The measurement of serum total protein (TP) is commonly performed by the biuret method. Refractometery which is less expensive and faster method also determines serum protein; however its accuracy is controversial. Therefore the primary objective of this study was to investigate portable refractometer as an alternative method to the biuret assay for measuring total serum proteins in horse serum. Serum from 50 male horses admitted to the society of the protection of animals’ abroad (SPANA) clinic was collected and measurement of serum total protein determined using portable refractometer and biuret method. The statistical differences between both methods were analyzed using a paired t-test and the correlation was determined by spearman correlation test. The results of this study demonstrate that there were no statistically significant variations in the mean total protein measured with the refractometer and biuret method (P > 0.05). The correlation between two methods using spearman correlations revealed high correlation between refractometry and biuret assay measurements of TP concentration r = 0.855. Bland–Altman plots indicated that biases indicating the analytic error was (4/50) 8% which is less than allowable total error for total protein determination (< 10%). Therefore portable refractometery can be used as an alternative to biuret method for serum total protein in horse as it is easy to use, quick turnaround time, and is inexpensive.

Nebivolol ameliorates sepsis-evoked kidney dysfunction by targeting oxidative stress and TGF-β/Smad/p53 pathway

Sepsis is a potential fetal organ destruction brought on through an overzealous immunologic reaction to infection, causing severe inflammation, septic shock, and damage to different organs. Although there has been progress in the identification and controlling of clinical sepsis, the fatality rates are still significant. This study, for the first time, intended to examine the possible ameliorative impact of Nebivolol, a β1-adrenergic antagonist antihypertensive drug, against nephrotoxicity resulted from cecal ligation and puncture (CLP)-induced sepsis in rats, on molecular basis. Sixty male Wistar albino rats were chosen. Oxidative stress indicators and biochemical markers of kidney activity were evaluated. Inflammatory mediators, fibrosis- and apoptosis-related proteins and gene expressions were investigated. Moreover, renal histopathological investigation was performed. CLP-induced nephrotoxicity characterized by markedly elevated serum levels of creatinine, blood urea nitrogen, uric acid, and renal malondialdhyde. On the other hand, it decreased serum total protein level, renal superoxide dismutase activity and reduced glutathione level. Additionally, it significantly elevated the renal inflammatory mediators (tumor necrosis factor-alpha, ilnerlukin (IL)-6, and IL-1β) and Caspase-3 protein, reduced IL-10 level, amplified the expression of transforming growth factor-beta 1 (TGF-β1), p-Smad2/3 and alpha-smooth-muscle actin proteins, downregulated the B cell lymphoma-2 (Bcl-2) gene and elevated the transcription of Bcl-2-associated X-protein (Bax), p53 and Nuclear factor-kappa B (NF-κB) genes. Furtheremor, kidney tissues exhibited significant histopathological changes with CLP. On the contrary, Nebivolol significantly improved all these biochemical changes and enhanced the histopathological alterations obtained by CLP. This research showed, for the first time, that Nebivolol effectively mitigated the CLP-induced kidney dysfunction via its antioxidant, antifibrotic and anti-apoptotic activity through modulation of oxidative stress, TGF-β/NF-κB and TGF-β/Smad/p53 signaling pathways.

Estimation of calories intake, iron, zinc, and selenium among children of the underprivileged area in Sindh, Pakistan.

Malnutrition is one of the most serious community health issues in developing countries. This study estimated total energy intake, Iron (Fe), Zinc (Zn), Selenium (Se), Calcium (Ca), and Phosphate (PO4) levels among school-going children (aged 13-17 years) of the underprivileged area in Sindh, Pakistan. Children from Mithi City, District Tharparkar, were selected for this cross-sectional investigation. Students from various schools from both genders who fulfilled the selection criteria were selected. A questionnaire was filled, and five ml blood samples were taken to analyze blood parameters. Each participant's estimated nutrient intake (ENI) per day was assessed and matched to the recommended daily allowance (RDA) to determine their micro and macronutrient intake. A total of 300 school-going children [150(50%) boys (mean age 15± 0.8 years) and 150(50%) girls (mean age 14±1.3years)] were included in this study. Total calories (1449±949 Kcal vs. 1245±215 Kcal; p < .001), carbohydrates (138±27 gm vs. 126 ±25 gm; p < .001) protein (47±9.1 gm vs. 44±6 gm; p < .001) was significantly higher among boys compared to girls. In contrast, calcium (1094±105 mg vs. 1144±100; 0.004), phosphate 1050±125 vs. 1148±147; p<0.001), iron (9.2±1.7 mg vs. 10±1.3 mg; p<0.001), and Zinc (7.4±1.8 mg vs. 9.9±1.7 mg; p<0.001) intake was significantly higher among girls than boys. Gender-wise comparison of serum metals in school-going children showed that serum iron was significantly lower among girls than boys (100.86±25.65 μg/dl vs. 78.48±28.66 μg/dl; p<0.001), and no difference was found in serum Zn, Se, and Ca levels. Total proteins were also significantly lower among girls than boys (6.48±1.01g/dl vs. 4.87±1.4301g/dl; p<0.001). Serum iron, Ca, and total proteins were significantly lower among girls with normal ranges compared to boys with normal ranges. Total protein was significantly lower among girls below normal ranges than boys with normal ranges (p < .001). The correlation of carbohydrates, protein, and fat with some serum biochemical parameters in school-going children showed that serum Fe was significantly linked with proteins (r = 0.255; p < .0.05). Our findings showed a concurrent shortage of macro and micronutrients. The current study also revealed that total energy intake was lower than the RDA and significant Fe, Zn, and Se deficiencies. The findings highlight the importance of measures aimed at improving children's nutritional status.

Relative merits of offering a milk replacer, glucose-electrolyte or whey-based diet on the blood composition and health of unweaned calves after transport

The objective of this randomized controlled trial was to assess the relative merits of offering unweaned calves 3 different types of diets to meet energy and water deficits that can occur during journeys. Six young unweaned male Holstein calves were randomly selected from within 2 body weight ranges (median 48 and 42 kg) from each of 29 loads (total n = 174 calves) transported from an auction market or a collection center to a calf sorting center before transport to a veal unit. The calves were then randomly allocated to one of 3 dietary treatments (n = 58 calves/dietary treatment). They were offered either a milk replacer diet (M), a glucose-electrolyte diet (G) or a whey-based diet with added electrolytes (W). The ability of these diets to provide sufficient nutrient energy to restore vigor, avoid hypoglycaemia and clinical signs of dehydration without increasing the risk of diarrhea was assessed. A clinical assessment of dehydration, health and vigor was made, and the calves were blood sampled before feeding, then 2 h and 4 h after feeding. The plasma glucose concentration was increased 2 h and 4 h after feeding the M and W diets. The increases in plasma glucose concentration were greater 2 and 4 h after (a) feeding the M than after the W diet and (b) feeding the M and W diets than after the G diet. Back-transformed means and 95% Confidence Intervals (CI) for the ratio of the plasma glucose concentration at 4 h compared with 0 h for the milk replacer, glucose-electrolytes and whey-based diets were 1.2 mM CI 1.21, 1.35; 0.95 mM CI 0.92, 0.97; and 1.09 mM CI 1.06, 1.14, respectively. There was no effect of diet on the change in serum total protein concentration between before feeding and 2 and 4 h after feeding. The serum osmolality was lower 2 h after feeding the G diet. The fall in serum osmolality was greater 2 h after feeding the G diet than after feeding the M and W diets. The changes in the serum osmolality between before feeding and 2 h after feeding for the milk replacer, glucose-electrolytes and whey-based diets were -0.68 mosmol CI -3.27, 1.91; -5.23 mosmol CI -7.82, and -2.64; -0.13 mosmol CI -2.77, 2.51, respectively. The diet offered at the sorting center had no effect on subsequent growth on the veal rearing farm between arrival and slaughter (milk replacer 1.22 kg/d, CI 1.17, 1.28; glucose-electrolyte diet 1.23 kg/d. CI 1.18, 1.28; whey-based diet 1.28 kg/d CI 1.23, 1.33). The M diet provided the calves with nutrients and water to replace energy and water deficits that had accumulated before arrival at the sorting center, and these dietary benefits were still apparent 4 h after feeding. The benefits of the W diet were similar to those of the M diet, but the M diet was better able to assist the calves in maintaining their plasma glucose concentration 4 h after feeding than the W diet. The G diet had some short-term benefits in providing energy and assistance to the calves to recover from dehydration, as indicated by a decrease in serum osmolality. However, the G diet was clearly inferior to the M and W diets in providing sufficient energy to assist the calves in recovering from the effects of transport and fasting. During the 4-h after feeding, no adverse effects of offering the calves the M or W diets were observed. The benefits of the W diet in replacing energy and water deficits were similar to those of the M diet, but the M diet was better able to assist the calves in maintaining their blood glucose concentration 4 h after feeding than the W diet.

Dietary threonine influences antioxidant capacity and immune status in juvenile largemouth bass (Micropterus salmoides)

As a restricted amino acid, threonine (Thr) deficiency reduces antioxidant and immune capacity in fish. In the present study, six diets containing different Thr levels (1.39 %, 1.71 %, 1.95 %, 2.28 %, 2.58 %, and 2.65 %) were fed to largemouth bass (15±0.1 g) for 60 days. The present results showed that neither growth nor whole-body composition was affected by different Thr levels. And low dietary Thr levels (1.39 %) significantly decreased serum total protein (TP) and albumin (ALB) levels, but increased alkaline phosphatase (ALP) levels. And 1.39 % Thr diet significantly decreased liver catalase (CAT) activity but increased malonaldehyde (MDA) levels, and the maximum total antioxidant capacity (T-AOC) was observed in response to the 1.95 % Thr diet. Liver proapoptotic factors (bax and caspase9) were significantly elevated in fish fed the 1.39 % Thr diet. The nuclear factor κB (nf-κb) and the NF-κB-mediated inflammatory cytokines were significantly increased in fish fed the 1.39 % Thr diet. The mRNA levels of protein kinase R (PKR)-like endoplasmic reticulum kinase (perk), eukaryotic translation initiation factor 2 (eif2α), activating transcription factor 4 (atf4), and C/EBP-homologous protein (chop), which are factors in the PERK/ATF4/CHOP pathway, one of the unfolded protein response (UPR) signaling pathways, were significantly increased by the 1.39 % Thr diet. The present study showed that low dietary Thr levels caused oxidative damage, reduced immunity, might affected PERK-ATF4-CHOP signaling to induce apoptosis, and via NF-κB signaling to trigger an inflammatory response in largemouth bass. Based on the TP, ALB, CAT, and MDA levels, the dietary Thr requirements for juvenile largemouth bass were estimated to be 2.18 %, 2.29 %, 1.92 %, and 1.88 %. Furthermore, these findings provided a new perspective that low dietary amino acid levels may trigger apoptosis and inflammatory responses in fish through the UPR signaling pathway.

Effects of Fermented Navel Orange Pulp on Growth Performance, Carcass Characteristics, Meat Quality, Meat Nutritional Value, and Serum Biochemical Indicators of Finishing Tibetan Pigs.

In order to cope with the limited supply of feed for global animal production, there is a pressing need to explore alternative feed resources. Orange pulp, a by-product of agriculture and industry, has shown potential to positively or neutrally impact pig productive performance when included in their diet. However, there is a lack of research on the effects of fermented navel orange pulp (FNOP) on pig growth and productive performance. This study aimed to investigate the effects of FNOP as a dry matter substitute on pig's growth performance, carcass characteristics, meat quality, meat nutritional value, and serum biochemical indicators. The experiment involved 128 finishing Tibetan pigs, divided into four feed treatment groups, with varying levels (0%, 5%, 10% and 15%) of FNOP replacing dry matter in the basal diet. The results indicate that substituting 5% to 15% FNOP had no adverse effects on pig growth performance. However, at a 15% substitution rate, there was a decrease in serum growth hormone and IGF-1 levels, along with an increase in the feed-to-gain ratio. A 10% FNOP replacement notably increased the loin-eye muscle area of pigs. Additionally, 5% and 10% FNOP substitutions reduced the drip loss of pork. The study also found that substituting 5% to 15% FNOP increased unsaturated fatty acids and umami nucleotide contents in pork and raised serum total protein and uric acid (nucleotide-metabolism-related product) levels. These findings suggest that moderate FNOP substitution might improve meat quality, nutritional value, and maintain growth and productive performance in Tibetan pigs by improving protein synthesis and nucleotide metabolism, while also reducing feed costs. The optimal substitution ratio identified was 10%.

Juvenile Cellulitis in a Labrador retriever- A case report

A labrador retriever pup aged 50 days was brought to Madras Veterinary College Small animal outpatient Unit with a history of anorexia, pyrexia, dullness with papules and pustules over muzzle and ear pinnae since three days. Facial edema, periocular edema and enlargement of pre scapular and submandibular lymphnodes were noticed on clinical examination. After complete physical examination, blood samples, skin scrapings, samples for bacterial culture and cytology were taken. Hemogram revealed anemia, serum biochemistry revealed low serum total protein concentration, skin scrapings were negative for parasites, no growth was present on bacterial culture from aspirated pustules, cytology from moist lesions showed presence of neutrophils and cocci. Based on the physical examination, hematological, biochemical and microbiological investigations, the present case was diagnosed as Canine Juvenile cellulitis and treatment initiated with antibiotic and corticosteroid parenterally for three days. There was a remarkable improvement noticed with reduced facial edema, reduced periocular edema and dry external ear pinnae. Treatment was continued with oral antibiotic for seven days and the pup recovered uneventfully.
