SERUM AND ASCITES FLUID BIOCHEMICAL PROFILEOF EFFUSIVE-TYPE FELINE INFECTIOUS PERITONITIS

Feline Infectious Peritonitis (FIP) is a fatal disease occurring in cats worldwide caused by Feline Coronavirus. Antemortem diagnosis of FIP is difficult due to non-specific clinical and laboratory signs. Rapid and reliable diagnosis is essential for prognostic purposes. The study was aimed to evaluate the serum biochemical profile and ascites of cats with effusive FIP. This study used five cats suspected of effusive FIP as a samples. Diagnosis was based on clinical examination, Rivalta and rapid test of FIP antibodies to ascites samples. Blood serum and ascites fluid were collected for examination of total protein, albumin, globulin and albumin/globulin (A/G) ratio. Clinical examination results showed that 5/5 (100%) cats had ascites. Rivalta test on ascites sample was positive for exudate and antibody rapid test was positive for FIP. The biochemical test showed an average total serum protein and ascites fluid of 7.14 ± 1.36 g/dL and 6.12 ± 0.33 g/dL (P<0.05); hypoalbuminemia was found in serum samples with an average of 1.94 ± 0.33 g/dL and ascites fluid albumin of 1.69 ± 0.32 g/dL (P<0.05), serum globulin had an average of 5.06 ± 1.32 g/dL and ascites globulin of 4.80 ± 0.88 g/dL (P>0.05). All cats had a low mean A/G ratio of 0.37 ± 0.36 in serum and 0.34 ± 0.01 in ascites (P>0.05). Concluded that the biochemical profile of serum and ascites in effusive FIP included normal total protein, hypoalbuminemia, normal serum globulin and decreased A/G ratio. Moreover, significant statistical discrepancy in serum and ascites biochemical profiles only occurred in total protein and albumin, but not in globulin and A/G ratio.

Assessment of the digestibility, growth performance, hematological and serum biochemical profile of Bandjock Local Pigs (BLP) and Duroc X Large White pigs (DLW)

The study aimed to assess the digestibility, growth performance, and selected biochemical and hematological parameters of Bandjock Local pigs (BLP) and Duroc X Large White pigs (DLW). We hypothesize that the use of local ingredients in diet formulation associated to improved rearing conditions, enhance the growth performance, digestibility, biochemical and hematological parameters of BLP. The trial involved dividing twenty-four eight-week-old weaner pigs into two groups. Each group was randomly assigned to separate pig units. Animal management and feeding were consistent between both groups. The trial lasted for 120 days during which the growth performance, the digestibility of ingested nutrients, and biochemical and hematological parameters were evaluated. The results indicate that DLW pigs registered a weight gain (46.56±5.19 kg) significantly higher than BLP pigs (34.02), with a statistically similar feed conversion ratio. Except for albumin which was significantly higher in DLW and urea in BLP, there were no significant differences (p > 0.05) in total protein, cholesterol, globulin, triglycerides, creatinine, AST, and ALT as well as hematological parameters between the breeds. However, the exotic DLW had a relatively high mean blood platelets and white blood cell concentration. Although the fecal nitrogen was higher in BLP and the urinary nitrogen was lower in the DLW, there were significant differences (p < 0.05) for urine, fecal, and total excreted nitrogen in both breeds. The lowest scores in nutrient digestibility were recorded with BLP compared to DWL, except for crude fibers. The results of this study demonstrated that using diet formulated with local ingredients and improved rearing conditions, Cameroonian local indigenous pigs have a better productivity compared to exotic breeds. It suggests that efforts should be made by authorities to promote and valorize the rearing of indigenous pigs in complement to exotic pig breeds in view of strengthening the Cameroonian pig industry.

Effects of Dietary Inclusion of Angelica gigas Nakai root extract on the Growth Performance, Hematological and Serum Biochemical Parameters in Broilers

The study aimed to evaluate the impact of dietary supplementation with Angelica gigas Nakai (AGN) root extract on growth performance, hematological indices, and serum biochemical parameters in broiler chickens. A total of 320 straight-run Cobb broiler chicks from a commercial hatchery were distributed among four treatment groups: Basal diet (BD) as the Control; Treatment 1 (T1): BD + 2 g/kg AGN; Treatment 2 (T2): BD + 4 g/kg AGN; and Treatment 3 (T3): BD + 8 g/kg AGN), each comprising eight replicates with 10 birds per replicate. The supplementation of AGN resulted in dose-dependent improvements (P &lt; 0.05) in body weight, gain, and feed efficiency. On both day 21 and day 35, increasing AGN dosage in the diet led to a significantly higher (P &lt; 0.05) values of red blood cells (RBCs), white blood cells (WBCs), hemoglobin (Hb), and packed cell volume (PCV). By day 21, AGN supplementation dose-dependently decreased (P &lt; 0.05) serum alkaline phosphatase (ALP), aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), urea, and creatinine levels. Meanwhile, AGN dose escalation correlated with a notable increase (P &lt; 0.05) in serum total protein (TP), albumin, and globulin levels. On day 35, increasing AGN levels led to a significant reduction (P &lt; 0.05) in serum AST and ALT activity, along with lowered serum glucose, cholesterol, triglycerides, urea, and creatinine levels. In conclusion, AGN supplementation enhanced growth performance and positively influenced hematological indices and serum biochemistry profiles in broiler chickens. The study confirms the safe and effective utilization of AGN at an 8 g/kg (0.8 %) feed additive dosage to optimize broiler performance. These findings provide valuable insights into the potential benefits of AGN in poultry nutrition.

Viscoelastic coagulation monitoring parameters in cats with acute arterial thromboembolism.

Hypercoagulability has been documented in cats with cardiac disease. However, hemostatic parameters, including viscoelastic coagulation monitoring (VCM) have not been reported in cats with arterial thromboembolism (ATE). Compare VCM parameters in cats with acute cardiogenic ATE and in control cats. Sixteen cats with ATE and 30 control cats. Multicenter university-based prospective study. Cardiogenic ATE was diagnosed based on physical examination and by ultrasonographically-diagnosed left atrial enlargement. Viscoelastic coagulation monitor analysis, CBC, serum biochemistry profile and coagulation profile were performed at admission in cats with ATE. Analysis from healthy control cats was performed using blood collected by direct venipuncture. Our objective was comparison of VCM parameters clot time (CT), clot formation time (CFT), alpha angle (Angle), maximum clot formation (MCF), amplitude at 10 and 20 minutes (A10 and A20, respectively) and clot lysis index at 30 and 45 minutes (LI30 and LI45, respectively) between ATE and control cats. Cats with ATE had a decreased angle compared to control cats, with a median (range) of 43° (30-48°) compared to 47° (14-59°; P = .01). The parameters A10, A20 and MCF were decreased in ATE cats compared to control cats with a median (range) of 19 units (8-32) compared to 22 units (6-38), 24.5 units (11-40) compared to 29 units (10-47) and 29.5 units (13-44) compared to 33.5 units (14-53), respectively (P = .01, .01 and .01, respectively). The parameters CT, CFT, LI30 and LI45 were similar between groups (P = .22, .09, .62 and .34, respectively). Cats with cardiogenic ATE cats have VCM parameters consistent with hypocoagulability compared with healthy cats.

Interplay of hormones and metabolite excretion with fern pattern prove saliva as a potent indicator of male reproductive status in Kangayam breed cattle.

Kangayam cattle are one of the drought breeds in India with distinct attributes. Agricultural transformation has led to a decline in many pure-breed indigenous cattle, including the Kangayam breed. Hence, a study on the reproductive physiology of male Kangayam breed cattle is necessary to disentangle problems in the area of livestock improvement. In this study, we investigated the relationship between serum hormones and bio-constituents and ascertained the potential of saliva as an indicator of the reproductive status of Kangayam cattle (Bos indicus). The present study confirms that cholesterol was higher in intact males and lower in prepubertal and castrated males. Testosterone levels were also higher in intact males than in castrated or prepubertal males. Hence, it can be inferred that high cholesterol levels contribute to active derivatization of testosterone in intact males. In contrast, reduced cholesterol availability leads to decreased testosterone synthesis in castrated and prepubertal males. Furthermore, it is reasonable to speculate that testosterone could have influenced salivary fern patterns in intact males, and thus, fern-like crystallization in the saliva was apparent. The unique salivary compounds identified through GC-MS across various reproductive statuses of Kangayam males may advertise their physiological status to conspecifics. In addition, the presence of odorant-binding protein(OBP) in saliva further supports its role in olfactory communication. This study attested to a posssible interlink between gonadal status and serum biochemical profiles. The salivary fern pattern revealed in this study can be used as a predictive tool, and the presence of putative volatiles and OBP adds evidence to the role of saliva in chemical communication.

Determination of Serum Biochemical Profile and Oxidant-Antioxidant Activities in Damascus Goats at Different Ages

This study aimed to research changes in biochemical profile and oxidant-antioxidant activities of Damascus goats of different ages. The 45 non-gravid Damascus goats of different ages were included in the research. They were divided into three groups of 15 goats according to age: goat kids ( - ≤ 6-months age), young goats (2-3-year age) and old goats (5-8-year age). Biochemical parameters and oxidant-antioxidant activities were determined in serum samples using commercial kits and colorimetric methods. The lowest serum urea, blood urea nitrogen, aspartate aminotransferase, total protein, albumin, globulin and magnesium levels were observed in goat kids (P &amp;lt; .05). Concentrations of glucose, inorganic phosphorus, non-esterified fatty acids, albumin/globulin and alanine aminotransferase decreased with age in the goats (P &amp;lt; .05). Serum total oxidant capacity, total antioxidants capacity and oxidative stress index levels were increased in goat kids compared to old goats (P &amp;lt; .05). Furthermore the highest serum glutathione and glutathione preoxidase activities were observed in young goats (P &amp;lt; .05). An increase was determined in concentrations of serum β-carotene and bilirubin in old goats compared to goat kids (P &amp;lt; .05). In contrast, serum catalase activity, arylesterase, ceruloplasmin and uric acid values did not differ between the groups. The results obtained on the biochemical profiles and oxidant-antioxidant activities of Damascus goats will contribute to monitoring this breed's age-related health and nutritional status and establishing reference values.

Antioxidant Effects of Whey Protein as a Dietary Supplement to Alleviate Cadmium-Induced Oxidative Stress in Male Wistar Rats

The liquid whey is a byproduct produced during cheese making. Cadmium is a highly hazardous heavy metal with cumulative toxic effects. The present research work was done to clarify the possible role of whey proteins in alleviating cadmium-induced oxidative stress. The used rats were allotted equally and randomly into three experimental groups; untreated control, cadmium-exposed, and cadmium-exposed and whey protein-administered groups. The biochemical and haematological assays of rats exposed to cadmium (group 2) manifested significant alterations compared to those of untreated control animals. Concerning the biochemical serum profile, group 3 animals showed relatively increased levels of total proteins, significant increments of total thiols, glutathione, total antioxidant capacity (TAC), and catalase, and significant decrements in the levels of blood cadmium, alanine transferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), creatinine, urea, bilirubin, hydrogen peroxide (H2O2), and malondialdehyde (MDA) compared to the animals exposed to cadmium (group 2). Homogenates of liver and kidney tissues obtained from group 3 animals demonstrated similar results to that revealed by the serum assay. It was concluded that whey proteins as a dietary supplement can offer potential antioxidant properties that enable these supplementary proteins to alleviate cadmium-induced oxidative stress.

Haematological and Serum Biochemical Responses of Yankasa Rams Supplemented Cinnamon Powder

This experiment was conducted to evaluate the effect of cinnamon supplements on Yankasa Rams' growth performance, nutrient digestibility, haematology and serum biochemical profile. A total number of sixteen (16) Yankasa grower rams with an average live weight of 20kg each was randomly allotted into four dietary treatments comprised of four replicates consisting of four animals per treatment in a completely randomized design (CRD), where data obtained in this study were analyzed using General Linear Model of Statistical Analysis Software and Means were separated using Duncan Multiple Range Test. The haematological variables demonstrated that packed cell volume was significantly (P&lt;0.05) affected by an increased level of cinnamon Significant (P&lt;0.05) differences were also recorded in white blood cells, neutrophils, basophils and haemoglobin while others were not significantly (P&gt;0.05) changed. With the exception of plasma potassium level, there were no significant (P&gt;0.05) differences in all other serum biochemistry with the supplementation of cinnamon. Cinnamon supplementation plays a vital role in improving the haematological profile. No significant considerable changes were observed in the serum biochemical profile as a result of cinnamon supplements in Yankasa rams. It is therefore recommended that cinnamon powder can be incorporated into ruminant animal diet up to 15g/kg without detrimental effect in animal health status. However further studies were encouraged.

Cardioprotective Effects of Aloysia polystachya Essential Oil on a Rat Model with Multiple Cardiovascular Risk Factors.

Traditional medicine is a frequently utilized method to treat cardiovascular disease and its primary risk factors, including hypertension and dyslipidemia. Aloysia polystachya is a species that is commonly employed to treat various pathological conditions, and it has already been identified as having some cardioprotective effects. This study aimed to investigate the protective effects of the essential oil extracted from the leaves of A.polystachya in a rat model that simulates multiple cardiovascular risk factors. We evaluate the acute toxicity, as well as the cardioprotective effects, by giving different doses of A.polystachya essential oil (1.47 mg/kg, 4.40 mg/kg, and 13.20 mg/kg) over a period of 42 days. The control group was treated with rosuvastatin (5 mg/kg). At the end of the treatments, the renal function, electrocardiography, blood pressure, vascular reactivity, serum biochemical profile, and organ histopathology were evaluated. The main compounds identified in the essential oil of A.polystachya using gas chromatography coupled with mass spectrometry were beta-myrcene (1.08%), limonene (40.13%), and carvone (56.47%). The essential oil of A.polystachya not only lacks acute toxicity but also mitigates the reduction in the excretion of sodium, chloride, and creatinine in urine. Furthermore, it reduces electrocardiographic abnormalities and decreases blood pressure levels. Moreover, this treatment prevents an elevation in markers of inflammation and oxidative stress in the bloodstream. Our findings indicate significant cardioprotective effects of the essential oil of A.polystachya against multiple risk factors for cardiovascular diseases in hypertensive rats.

Determination of the reference interval for urine kidney injury molecule-1 in 50 healthy cats.

The aim of the present study was to establish a reference interval (RI) for urine kidney injury molecule-1 (KIM-1) in healthy cats. History, physical examination, blood pressure, and feline immunodeficiency virus and feline leukemia virus serology status were determined. A complete blood cell count, serum biochemical profile, urinalysis and kidney ultrasound were performed, and N-terminal pro-brain natriuretic peptide, total thyroxine (TT4) and urine KIM-1 were measured. An RI was calculated and the effect of age, sex, body condition score (BCS), blood pressure, symmetric dimethylarginine (SDMA), serum creatinine concentration (SCr), phosphorus, TT4, urine specific gravity (USG) and mid-sagittal kidney length on urine KIM-1 was evaluated using a general linear model. Of 69 recruited cats, 50 met the inclusion criteria. There were 35 male cats and 15 female cats, with a median age of 4.3 years (range 1.0-12.3), median weight of 5.11 kg (range 2.52-8.45) and median BCS of 6/9 (range 3-8). The median serum concentrations were SDMA 11.0 µg/dl (range 2-14), SCr 88.5 µmol/l (range 47-136), phosphorus 1.41 mmol/l (range 0.8-2.2) and TT4 32.0 nmol/l (range 17-51). Median USG was 1.057 (range 1.035-1.076), mid-sagittal left kidney length was 3.50 cm (range 2.94-4.45) and mid-sagittal right kidney length was 3.70 cm (range 3.06-4.55). The derived RI for urine KIM-1 was 0.02-0.68. USG was a significant (P <0.001) predictor of urine KIM-1. Individually, age, sex, blood pressure, BCS, SDMA, SCr, phosphorus, TT4 and mid-sagittal kidney length were not significant predictors of urine KIM-1. In a multivariate model, if combined with USG, SDMA concentration was predictive (P = 0.030) of urine KIM-1. Urine concentration was significantly correlated with urine KIM-1, which will be an important consideration when interpreting findings in cats with potential kidney injury.

Nutritional response to water hyacinth (Eichhornia crassipes) challenges via blood biochemical profiles in goats and sheep

Eichhornia crassipes remains a significant threat to aquatic ecosystems and poses economic challenges globally. Interestingly, its high nutritional value and abundance in water bodies, making it a promising and cost-effective source of animal feed. The purpose of the study was to see how varying inclusion rates of E. crassipise affected the blood biochemical profiles of Doyogena sheep and Woyto-Guji goat local breeds. Twelve sheep and twelve goats were used in a 2*4 randomized crossover design with two species, four diets, and four phases (15-day adaptation plus 7-day experimental diets), and on the last day blood sample collected. The dietary treatments included E. crassipise (0, 25, 50, and 75%) as a substitute for commercial concentrate. The data were analyzed using SAS software tool PROC GLM, and Pearson's correlation coefficient between serum biochemical indices was computed. Results of AST, ALB, GLB, AST/ALT, and A/G showed significant (P < 0.0001), ALP (P < 0.005), and GLU (P < 0.05) differences between species of animals, except for ALT, CREAT, TP, and UREA. Sheep had higher values for AST, ALP, GLB, AST/ALT, CREAT, and UREA, except for A/G, ALB, ALT, and TP. Among treatments and treatment species interaction effect did not show variation in all studied parameters. Positive correlations were observed between ALT and AST, TP and ALB, and A/G and ALB, negative correlations were observed between ALT and AST/ALT, TP and A/G; GLB and A/G in sheep. Furthermore, positive correlations were observed between AST/ALT with ALT and AST and ALB with TP and A/G; however, negative correlations were observed between ALB with TP and A/G in goats. It was concluded that substituting E. crassipise with concentrate had no adverse effect on the serum biochemical profile.

Exploring the Role of Serum Osteonectin and Hsp27 in Pediatric MAFLD Diagnosis and Cardiometabolic Health.

Childhood obesity is one of the major challenges of public health policies. The problem of fatty liver in childhood, known as MAFLD (metabolic dysfunction-associated fatty liver disease), is of particular interest as the gold standard diagnosis technique is invasive (liver biopsy). Hence, efforts are made to discover more specific biomarkers for the MAFLD signature. Therefore, the aim of the study was to evaluate Osteonectin and Hsp27 as biomarkers for MAFLD diagnosis and to assess their links with auxological and biochemical profiles of overweight and obese pediatric subjects. A cross-sectional study in which we (re)analyzed data from the MR PONy cohort comprising 71 pediatric subjects. Auxological data, liver ultrasonography and biochemical serum profile were recorded. Lipid-derived indices and body composition indices were calculated. Nevertheless, serum Osteonectin and Hsp27 levels were assessed using an ELISA approach. MAFLD prevalence was 40.8%. Higher Osteonectin levels were noted in MAFLD subjects versus non-MAFLD subjects and in dyslipidemic children regardless of their liver function status. Lipid-derived indices had good diagnostic capacity for MAFLD. We confirm Osteonectin as a MAFLD diagnosis biomarker in children. Also, lipid-derived indices are useful as metabolic-associated organ impairment markers in children even before the onset of obesity.

Cymbopogon schoenanthus (L) extract ameliorates high fat diet-induced obesity and dyslipidemia via reducing expression of lipogenic and thermogenic proteins

Globally, obesity has become one of the major health problems. This study was conducted to evaluate the anti-obesity potential of Cymbopogon schoenanthus methanolic extract (CS) in rats. Fifty male Wistar rats of six to eight weeks old, 100–120 g body weight (BW) were randomly assigned into 5 groups (n = 10): The control group was fed a basal diet. CS-group was supplied with basal diet and orally given CS (200 mg/kg BW) for 12 weeks. HFD-group was fed a high-fat diet (HFD) for 18 weeks. HFD + CS-group was fed on HFD and CS HFD then CS-group was fed HFD for 12 weeks then shifted to basal diet and CS for another 6 weeks. Phytochemical analysis of CS indicated the presence of various terpenes and flavonoid compounds. Among the compounds characterized are quercetin, apigenin, luteolin, orientin, eudesmene, cymbopogonol, caffeic acid, coumaric acid, and linolenic acid. Supplementation of HFD significantly increased the body weight, levels of serum triacylglycerol, total cholesterol, very low-density lipoprotein, low-density lipo-protein (HDL), glucose, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities. In addition, HFD up-regulated the protein expression of uncoupling protein (UCP)-1 in both brown and white adipose tissue; and the expression of hepatic mRNA of sterol regulatory element-binding protein (SREBP)-1c and SREBP-2. However, it decreased the serum level of HDL, and protein expression level of UCP-1 in both brown and white adipose tissue. Treatment of HFD-fed animals with CS extract either concurrently (HFD + CS-group), or after obesity induction (HFD then CS-group) significantly reversed all HFD-induced alterations in body weight; food intake; serum biochemical profile (including hyperglycemia, dyslipidemia); and tissue gene expressions. These results indicate that CS methanolic extract ameliorated HFD-induced obesity, serum biochemical, hepatic, and adipose tissue gene expression alterations. CS extract accomplished these effects mostly through its various identified bioactive compounds which have been proven to have anti-obesity and anti-diabetic activities.

Response of serum biochemical profile, antioxidant enzymes, and gut microbiota to dietary Hong-bailanshen supplementation in horses.

Traditional Chinese medicine (TCM) is widely used in humans and animals, which is very important for health. TCM affects the body 's immunity and changes in intestinal flora. This study was conducted to investigate the effects of dietary Hong-bailanshen (HBLS) supplementation in horses on serum biochemical profile, antioxidant enzymes and gut microbiota. In this study, five horses were selected. On day 0, 14, 28, blood samples and feces were collected on days 0, 14, and 28 to analyse gut microbiota, serum biochemical and redox indexes. The results showed that the addition of HBLS to horse diets significantly decreased the level of alanine aminotransferase, alkaline phosphatase, creatine kinase and malondialdehyde (p < 0.05, p < 0.01) and significantly increased the activity of total antioxidant capacity, superoxide dismutase and catalase (p < 0.05, p < 0.01). Compared with day 14, the levels of alanine aminotransferase, alkaline phosphatase and creatine kinase were significantly decreased; however, the level of catalase was significantly increased in the horses continuously fed with HBLS for 28 days (p < 0.05, p < 0.01). Alpha diversity analysis was performed that chao1 (p < 0.05), observed_specicies, faith'pd and goods_coverage upregulated in the horses fed HBLS. A total of 24 differential genera were detected adding HBLS to diet increased the abundance of Bacillus, Lactobacillaceae, Leuconostocaceae, Christensenellaceae, Peptostreptococcaceae, Faecalibacterium, Erysipelotrichaceae, Pyramidobacter, Sphaerochaeta, WCHB1-25, Bacteria, Oscillospira, and Acetobacteraceae, while reduced Aerococcus, EtOH8, Syntrophomonas, Caulobacter, Bradyrhizobiaceae, W22, Succinivibrionaceae, and Desulfovibrio (p < 0.05, p < 0.01). Adding HBLS to the diet could be a potentially effective strategy to improve horses' health.

Preparation, Characterization, and Sub-Chronic Toxicity of Carvacrol-Self-Nano-Emulsifying Drug Delivery System Towards Healthy Sprague Dawley Rats

Background: Carvacrol (CAR) is the active component in essential oils (EOs) of many fragrant plants, including oregano and thyme; however, its high toxicity restricts its usage in biomedical fields, and the self-nano-emulsifying drug delivery system (SNEDDS) was suggested to overcome this issue. Objective: To prepare and characterize the CAR-loaded SNEDDS and to assess its toxicity profile towards healthy rats using the in vivo sub-chronic study. Methods: SNEDDS was prepared from olive oil, dimethyl sulfoxide, Tween-80, and distilled water, then CAR-SNEDDS was prepared by adding 0.5% CAR to SNEDDS and both composites were gently agitated for 72 h at room temperature. Later on, both composites were physiochemically characterized for size/charge (Zetasizer), shape (TEM), crystallinity (XRAD), composition (FTIR), and quantitated (UV–Vis). Additionally, the sub-chronic toxicity of both composites at different doses was conducted by orally treating healthy Sprague Dawley for 4 weeks. Then, the treated rats were checked for toxicological symptoms, food/water intake, and behavioral abnormality. In addition, the blood samples were tested for hematologic/biochemical changes, while vital organs (liver and kidney) were assessed for histopathological alterations. Results: The average globule size, zeta potential, and polydispersity index of CAR-SNEDDS were 158.93 ± 22.18 nm, −22.56 ± 1.77 mV, 0.553 ± 0.31, respectively. All treated animal tissues, serum biochemical profiles, and total hemograms were normal. At 30-90 mg/kg oral doses, CAR-SNEDDS was not toxic and did not cause mortality. Conclusions: CAR-SNEDDS was successfully synthesized and characterized, and the results from sub-chronic oral toxicity studies showed that the CAR-SNEDDS were non-toxic and safe for biomedical fields.

Comparative evaluation of the serum biochemical and lipid profile changes in spayed male and female rats

Background and aims: This study investigated the effects of gonadal removal in male and female rats on changes in serum biochemical parameters. Methods: Twenty-eight adult male and female rats were divided into four groups of 7 animals for a period of 9 weeks. The first and second groups of intact male and female rats, as well as the third and fourth groups of male and female rats, were gonadectomized, respectively. At the end of the ninth week of the study, the rats were anesthetized with chloroform, and the amount of glucose, some lipid parameters in serum, and the activity of a number of serum enzymes were measured after taking blood from the heart. Results: Alanine aminotransferase, and alkaline phosphatase (ALP) levels were higher in intact male rats than in intact female rats, respectively (P=0.03, P=0.015). The amounts of glucose and cholesterol of low-density lipoprotein (LDL) in intact female rats were higher than in the ovariectomized rats, respectively (P=0.07, P=0.039, P=0.03). The amount of lactate dehydrogenase (LDH) in spayed female rats demonstrated a significant increase compared to other groups (P=0.001). However, there was a significant decrease in calcium levels in gonadectomized rat groups in comparison to intact female rats (P=0.02). Finally, a significant increase was found in phosphorous levels in the intact male rats group compared to other groups (P=0.002). Conclusion: Decreased sex hormones in gonadectomized rats compared with intact rats could lead to increased serum levels of LDH, ALP, and LDL cholesterol that may result in the development of metabolic and atherogenesis syndromes and acute liver failure.

Effects of Choline Supplementation in Diets on Juvenile Pacu (Piaractus mesopotamicus): Productive Performance, Proximate Composition and Serum Lipid Level.

Pacu (Piaractus mesopotamicus) is a Brazilian fish species of high commercial value and has emerged as one of the main species with potential for intensive farming. This study aimed to investigate the impact of choline supplementation on productive performance, visceral fat, hepatosomatic indices, proximate composition, serum biochemical profile, and liver coloration in juvenile pacu (Piaractus mesopotamicus). The 60-day experiment was conducted in the experimental hatchery of the Study Group of Aquaculture Management - GEMAq of the State University of West Paraná, Brazil. The completely randomized design consisted of five treatments with four replicates each. A total of 200 fish, with an average initial weight and length of 4.25 g and 5.97 cm, were distributed among 20 experimental hapas, resulting in a stocking density of 10 fish per experimental unit. Fish fed a choline-deficient diet exhibited the lowest values for final weight, weight gain, visceral fat, and hepatosomatic index. Conversely, in terms of proximate composition, fish fed choline-deficient diets had the highest moisture content but the lowest crude fat content. Triglyceride levels in juvenile pacu were significantly higher in groups fed diets containing choline (400 to 1200 mg kg-1 ). We also observed significant differences in the cyan color of the liver (P < 0.05). Notably, we observed significant differences in the cyan coloration of the liver (P < 0.05). Other parameters did not exhibit significant changes in response to varying choline levels in the diets. Our study demonstrated that choline supplementation in P. mesopotamicus juveniles at an optimal concentration of 400 mg kg-1 significantly impacted growth, metabolism, productive performance, proximate composition, biochemical parameters, and liver color. These findings offer crucial guidance for aquaculture professionals, enabling them to enhance growth and health in P. mesopotamicus farming. Further research on choline's influence on lipid metabolism holds potential for more precise dietary recommendations, ultimately improving the efficiency and sustainability of aquaculture practices for this species.

Effect of Nano Vitamin E and Selenium Supplementation on Serum Biochemical Profile in Japanese Quails

This study investigated the impact of nano vitamin E with Selenium on serum parameters in Japanese quails. The experiment involved three groups: a control group (C1) fed a basal diet, a T1 group receiving vitamin E (150mg/kg) and Selenium (0.3mg/kg), and a T2 group receiving nano vitamin E (15mg/kg) and Selenium (0.03mg/kg). Results revealed significant differences (p&lt;0.05) in serum analyses among the groups. The T2 group showed the highest total protein and globulin levels, while the T1 group exhibited the highest total albumin levels. Total cholesterol levels were significantly lower in the T2 group, with the highest HDL cholesterol. LDL cholesterol levels were lower in the T2 group. SGOT and SGPT levels were significantly lower in the T2 group. These findings suggest the potential benefits of nano vitamin E with Selenium in modulating serum biochemistry in Japanese quails.
