This study aimed to evaluate the effect of the combination of estradiol-17β hormone and spirulina in feed on blood plasma biochemistry, histology, and gonad development of female bada fish (Rasbora argyrotaenia). The research method were an experimental study using a completely randomized design with four treatment combinations and four replications, namely without the addition of the estradiol-17β hormone and spirulina (P0), the addition of the estradiol-17β hormone at 7 g kg-1 feed (P1), the addition of spirulina at 30 g kg-1 feed (P2) and the addition of the estradiol-17β hormone at 7 g kg-1 feed and spirulina at 30 g kg-1 feed. Female bada fish (4.22±1.28 g) were kept in an aquarium measuring 100x50x50 cm3 with a density of seven individuals per aquarium. Fish were fed the treatment twice daily, with 3% of the biomass for six weeks. The test parameters were estradiol-17β hormone concentration, egg diameter, blood plasma glucose concentration, blood plasma total cholesterol concentration, and gonadal histology observations. The experimental results showed that the concentration of the estradiol-17β hormone in the body plasma of treatments P1 and P3 was statistically significantly different (P<0.05) compared to treatments P0 and P2. The combination of estradiol-17β hormone and spirulina added to the feed gave not significantly different results (P>0.05) on blood plasma biochemistry and egg diameter of bada fish broodstock. A combination of estradiol-17β hormone and spirulina hormones in the feed resulted in better P1 and P3 treatments with higher plasma concentrations of the estradiol-17β hormone. Observations of gonadal development from histology showed that the bada fish gonads belonged to the asynchronous type.

Leflunomide is an antirheumatic drug with anti-inflammatory and antirheumatic properties, it is rapidly metabolized in the body to the active metabolite teriflunomide, which causes its pharmacological activity. At the usual 20-mg daily dosage of leflunomide, the expected teriflunomide plasma concentration is about 35 μg/ml. The pharmacokinetics of the drug is characterized by a large interindividual variability and a long half-life, which in combination with possible side effects creates the need to control the concentration of teriflunomide in the blood plasma. Teriflunomide may increase the risk of fetal death or teratogenic effects when administered to pregnant women. Teriflunomide plasma concentrations less than 0.02 μg/ml are preferred for patients anticipating pregnancy. In this study, a sensitive and high-performance method for analyzing teriflunomide in human blood plasma in a wide range of concentrations was developed and validated using a triple quadrupole liquid chromatography-mass spectrometer (HPLC-MS/MS). Sample preparation was performed by protein precipitation with acetonitrile, followed by chromatographic separation using an Acquity UPLC BEN C8 1.7 mm, 2.1 × 50 mm column (Waters, USA). D4-teriflunomide was used as an internal standard. The developed method was validated in the concentration range from 0.001 μg/ml to 200 μg/ml teriflunomide in plasma. Accuracy (%), defined as the difference between the nominal and measured concentration and reproducibility (coefficient of variation CV) ranged from -5.02% to 5.00% and from 0.47% to 9.30%, respectively, within the series and between series of samples. The developed method was successfully used to analyze volunteer blood plasma samples after taking 20 mg of leflunomide.

A total of one hundred and fifty (150) Nera ser-linked layer strains (32 weeks of age) were used to investigate the performance response, blood plasma and egg yolk cholesterol status of hens fed cassava roul sievate (CRS) bused - diets. CRS was used to replace wheat offal at 0, 5, 10, 15 und 20% respectively, resulting in five dietary treatments. Each treatment had 3 replicates with each replicate group having five hirds. The experiment lasted for 10 weeks. No significant effect of diers was noticed in the body weights, weight gain and daily feed intake. Fced conversion per dozen eggs, hen-day egg production and total egg produced significantly declined as CRS levels increased from 0 to 20% in the diets. Diets with 20% CARS had the poorest performance. However, the blood plasma, egg yolk and egg cholesterol concentrations were reduced significantly (p< 0.05) with increased level of CRS Dietary treatment with 20 % CARS had the lowest (P< 0.05) cholesterol concentration. Inclusion of up to 20% CRS led to 35% reduction in plasma total cholesterol, while 18 and 17% reductions were obtained in the egg yolk total cholesterol and total cholesterol per egy respectively. Replacement of up to 10% (w/w) wheat offal by CRS is therefore recommended 10 effectively reduce cholesterol content of the plasma ,egg yolk and whole egg by 20%, 10% and 17 % respectively at performance level that are comparable with that of the control group.

Abstract. Title of the paper: Cholesterol concentration in yolks and blood plasma in five species of game birds (short communication) Cholesterol concentrations were determined in yolks and blood plasma of five significant species of game birds (common partridge, wild turkey, common pheasant, guinea fowl, and chukar partridge). Two yolk samples and one blood plasma sample were collected from 15 female birds of each species. Dimensions, whole egg weight and weights of sheli, yolk, and white were recorded for each egg. Mean blood plasma concentrations were significantly higher (P < 0.01) in the common partridge (3.44 mmol/1), the wild turkey (3.78 mmol/1), and the common pheasant (3.67 mmol/1) than in the guinea fowl (2.61 mmol/1) and the chukar partridge (2.26 mmol/1). Mean yolk cholesterol concentrations in the wild turkey (1030 mg/100 g), the guinea fowl, and the chukar partridge (both 1010 mg/100 g) were significantly higher (P < 0.01) than in the common pheasant (960 mg/100 g) and the common partridge (930 mg/100 g/1). Mean blood plasma cholesterol concentrations exceeded mean yolk concentrations by a 7- to !2fold. Blood plasma cholesterol concentrations were near the lower limit of the normal range for domestic fowl, while yolk concentrations in the game birds were markedly lower than in the domestic chicken.

AbstractWe studied the long-term effect of ileal transposition (IT) metabolic surgery on the hepatokines: retinol-binding protein-4 (RBP4), α-2-HS-glycoprotein (aHSG/fetuin-A), and fibroblast growth factor 21 (FGF21), C-reactive protein (CRP) plasma levels, glucose metabolism, body weight, liver histology, as well as total lipids concentration in muscle, liver, and fat tissue of obese Zucker (Crl:ZUC(ORL)-Leprfa) rats. 14 adult males were randomly submitted either to IT or SHAM (control) surgery. Pre-operative hepatokines plasma levels were not significantly different in rats submitted to IT or SHAM protocol. Three months after the procedures the plasma levels of RBP4, aHSG, FGF21, and CRP were significantly lower in IT-operated animals when compared to SHAM-operated group. Three and 12 weeks after the IT and SHAM surgery, the AUCOGTT were significantly lower than AUCOGTT before the surgery. HOMA-IR was lower in rats after IT surgery in comparison to the SHAM-operated rats. Muscle and liver total lipids concentration was reduced after the IT procedure when compared to pre-IT conditions. IT had a significant reductive impact on the body weight in comparison to SHAM surgery in the 4th, 6th, 8th, and 10th week after the surgery. We conclude that IT reduces hepatokines’ plasma concentrations, muscle and liver total lipids concentration but not the inflammatory processes in the liver of Zucker (Crl:ZUC(ORL)-Leprfa) rats.

Abstract Background In molecular imaging with dynamic PET, the binding and dissociation of a targeted tracer is characterized by kinetics modeling which requires the arterial concentration of the tracer to be measured accurately. Once in the body the radiolabeled parent tracer may be subjected to hydrolysis, demethylation/dealkylation and other biochemical processes, resulting in the production and accumulation of different metabolites in blood which can be labeled with the same PET radionuclide as the parent. Since these radio-metabolites cannot be distinguished by PET scanning from the parent tracer, their contribution to the arterial concentration curve has to be removed for the accurate estimation of kinetic parameters from kinetic analysis of dynamic PET. High-performance liquid chromatography has been used to separate and measure radio-metabolites in blood plasma; however, the method is labor intensive and remains a challenge to implement for each individual patient. The purpose of this study is to develop an alternate technique based on thin layer chromatography (TLC) and a sensitive commercial autoradiography system (Beaver, Ai4R, Nantes, France) to measure radio-metabolites in blood plasma of two targeted tracers—[18F]FAZA and [18F]FEPPA, for imaging hypoxia and inflammation, respectively. Results Radioactivity as low as 17 Bq in 2 µL of pig’s plasma can be detected on the TLC plate using autoradiography. Peaks corresponding to the parent tracer and radio-metabolites could be distinguished in the line profile through each sample (n = 8) in the autoradiographic image. Significant intersubject and intra-subject variability in radio-metabolites production could be observed with both tracers. For [18F]FEPPA, 50% of plasma activity was from radio-metabolites as early as 5-min post injection, while for [18F]FAZA, significant metabolites did not appear until 50-min post. Simulation study investigating the effect of radio-metabolite in the estimation of kinetic parameters indicated that 32–400% parameter error can result without radio-metabolites correction. Conclusion TLC coupled with autoradiography is a good alternative to high-performance liquid chromatography for radio-metabolite correction. The advantages of requiring only small blood samples (~ 100 μL) and of analyzing multiple samples simultaneously, make the method suitable for individual dynamic PET studies.
