Nitrogenous Metabolism

The maturation of nitrogen metabolism was studied in six Thoroughbred and six Arabian foals. Rectal temperature, heart and respiratory rates and serum concentration of several hematochemical parameters (total protein, urea, uric acid, creatinine, and albumine) were monitored from birth to 5 months of age. In both breeds, all the parameters except albumine showed significant differences over time (P<0.05). The two breeds did not differ from each other at any time point. Statistically significant decreases in urea and creatinine concentrations were related to the growth needs of foals during this critical period of development.

Abstract Background Latest studies indicated that the general mental health level is low during the pandemic. Probably, this deterioration of the mental health situation is partly due to declines in physical activity. The aim of this study was to investigate differences in and the association between affective wellbeing and levels of different domains of physical activity at three time points before and during the pandemic. Method We used a nationwide online panel with a trend data design encompassing a total sample of N = 3517, representing the German population (> 14 years). Four different activity domains (sport and exercise, light outdoor activity, housework/gardening, active travel) and affective wellbeing (positive and negative affect) were assessed at three time points before and during the Covid-19 pandemic (October 2019, March 2020, October 2020). Results Multivariate analyses of variance (MANOVA) indicate differences regarding affective wellbeing over the three time points with the lowest values at the second time point. Levels of activity in the four domains differed significantly over time with the strongest decrease for sport and exercise from the first to the second time point. Partial correlations indicated that the relationships between sport and exercise and positive affect were most consistent over time. Conclusions Overall, our findings suggest that physical activity plays a particularly important role in the pandemic period as a protective factor against poor mental health. Especially sports and exercise seem to be supportive and should be encouraged, e.g. by providing additional support in finding adequate outdoor, home-based or digital substitutes.

Objectives: The aim of this study was to investigate quadriceps and hamstrings isometric strength at 4, 8 and 12 week time points following ACL Reconstruction (ACLR) and to document the strength changes of these muscles over time. The primary hypothesis was that there would be significant increases in quadriceps and hamstring muscle strengths between the 4th, 8th and 12th weeks following ACLR. The secondary hypothesis was that the quadriceps index would be higher than hamstring index at 12th week after ACLR. Methods: Thirty patients (Mean ± SD [age, 29.1±2.3yrs; weight, 77.3±13.2kg; height, 172.1±7.1cm; BMI, 21.2±3.5kg/m2, time to surgery: 7.1±7.2 months]) who underwent ACLR with Hamstring Tendon Autograft (HTG) were enrolled in this study. The isometric strength of quadriceps and hamstring muscles was measured on an isokinetic dynamometer at 60° knee flexion angle at 4th, 8th and 12th weeks after surgery. The recovery of quadriceps and hamstring muscles strength following rehabilitation was expressed as a Quadriceps Index (QI) and Hamstring Index (HI) and calculated with the following formula:[(maximum voluntary isometric torque of the involved limb / maximum voluntary isometric torque by uninvolved limb) × 100]. Torque output of the involved and uninvolved limbs and quadriceps and hamstring indexes were used for the statistical analysis. A repeated measures of ANOVA was used to determine the strength changes of quadriceps and hamstrings over time. Results: Quadriceps and Hamstrings strengths significantly increased over time for both involved (Quadriceps: F (2,46)=58.3, p<0.001, Hamstring: F (2,46)=35.7, p<0.001) and uninvolved limb (Quadriceps: F(2,46)=17.9, p<0.001, Hamstring: F(2,46)=56.9, p=0.001 ). Quadriceps strength was higher at 12th week when compared to the 8 and 4 week time points for the involved limb (p<0.001), and it was higher at 8th week when compared to 4 week time point for the involved limb (p<0.001). For the uninvolved limb, quadriceps strength was also higher at 12th week when compared to the 8 (p=0.02) and 4 week time point (p<0.001), and higher at 8 week when compared to the 4 week time point (p=0.02). Hamstring strength was higher at 12 week when compared to the 8 and 4 week time points (p<0.001) and it was higher at 8 week when compared to 4 week time point for the involved limb (p<0.001). For the uninvolved limb hamstring strength was also higher at 12 week when compared to 4 week time point (p=0.01). There was no significant difference between the 4 and 8 week time points (p>0.05) or between the 8 and 12 week time points (p=0.07). Quadriceps and hamstring indexes significantly changed from 4th weeks (QI:57.9, HI:54.4 ) to 8th weeks (QI:78.8, HI:69.9 ) and from 8th weeks to 12th weeks (QI:82, HI:75.7 ) (p<0.001); however, there was no difference between indexes at the 12-week time point (p=0.17). Conclusion: Isometric strength of quadriceps and hamstring muscles for the involved and uninvolved limb increased during the early period of ACLR. The results of this study could be a baseline for clinicians while prescribing a rehabilitation protocol for ACLR patients with HTG to better appreciate expected strength changes of the muscles in the early phase.

Objectives. Preeclampsia is a pregnancy specific syndrome. Studies have shown that preeclampsia has multiorgan dysfunction effects. This study evaluated biomarkers of renal and liver function among preeclamptic Nigerian women. Study Design. This was a cross-sectional study conducted among 49 preeclamptic women and 50 normotensive healthy pregnant women. Method. The baseline data comprising age, gestational age, and blood pressure were obtained. Venous blood and spot urine samples were collected from each participant. Plasma obtained from blood samples taken into lithium heparinized vacutainer bottles was assayed for electrolytes, urea, creatinine, total protein, albumin, and uric acid, while sera samples from blood samples taken into serum separation tube- (SST-) gel vacutainer were assayed for aspartate transaminase and alanine transaminase using ion selective electrode technique and Cobas autoanalyzer. Spot urine samples were assayed for protein and creatinine using Pyrogallol’s reagent and Jaffe’s methods, respectively. Microalbuminuria (protein/creatinine ratio) was generated from spot urine protein and creatinine data. Result. The plasma sodium, total protein, and albumin in preeclamptic group were significantly decreased (p<0.05) when compared with control. There was statistically significant increase (p<0.05) in microalbuminuria, plasma potassium, urea, creatinine, uric acid levels, serum AST, and ALT activities in preeclamptic group. A positive association (p<0.05) between alanine aminotransferase and biomarkers of renal function was observed. Conclusion. Preeclampsia has deleterious effects on renal and liver function as shown by alteration of these parameters.

One hundred and thirty five 18weeks old Bovans Nera Black strain pullets were used in a 10week study to determine their heat balance and blood profile under varying stocking density in locally fabricated metal-type cage system. The cages were stocked 2, 3 and 4birds/cell. Daily ambient temperature and relative humidity of the cage and rectal temperature of the birds were taken and heat balance calculated. Record of Packed cell volume (PCV), Haemoglobin concentration (Hb), Red blood cell (RBC), White blood count (WBC) and differential of the birds were taken at beginning and end of the study for the haematological indices while blood glucose, total protein, Albumin and blood urea were taken for the bio-chemical measurements. Ambient temperature, relative humidity, and heat balance showed no significant (P>0.05) difference with cage stocking density. Cage stocking density had significant (P<0.05) effect on rectal temperature of layers. Bird stocked 3/cell recorded the least (41.14oC) rectal temperature while those stocked 4/cell recorded the highest (41.27oC). All the haematological parameters of the birds were not significantly (P>0.05) influenced by stocking density of the cage type. Bio-chemical measurements were not significantly (P>0.05) different among layers under varying stocking density of the cage except total protein (P<0.05). Layers stocked 4/cell recorded highest (5.22g/dl) total protein while those stocked 3/cell had the least value (4.37g/dl). However, the values were within the normal range recommended for healthy chicken. The study concluded that locally fabricated metal-type battery cage could be used to rear layers and stocking density of 3birds/cell is ideal without compromising the welfare of the birds.

Abstract To evaluate the effect of an E. coli lipopolysaccharide (LPS) challenge on the digestible lysine (Lys) requirement for growing pigs, a nitrogen (N) balance assay was performed. Seventy-two castrated male pigs [19 ± 1.49 kg body weight (BW)] were allocated in a 2 x 6 factorial design composed of two immune activation states (control and LPS-challenged) and 6 dietary treatments with N levels of 0.94, 1.69, 2.09, 3.04, 3.23 and 3.97% N, as fed, where Lys was limiting, with six replicates and one pig per unit. The challenge consisted of an initial LPS dose of 30 μg/kg BW via intramuscular (IM) injection and a subsequent dose of 33.6 μg/kg BW after 48 h. The experimental period lasted 11 days and was composed of a 7-day adaptation and a subsequent 4-day sampling period in which N intake (NI), N excretion (NEX) and N deposition (ND) were evaluated. Inflammatory mediators and rectal temperature were assessed during the 4-day collection period. A 3-way interaction (N levels × LPS challenge × time, P &lt; 0.05) for IgG was observed. Additionally, 2-way interactions (challenge × time, P &lt; 0.05) were verified for IgA, ceruloplasmin, transferrin, haptoglobin, α-1-acid glycoprotein, total protein, and rectal temperature; and (N levels × time, P &lt; 0.05) for transferrin, albumin, haptoglobin, total protein and rectal temperature. LPS-challenged pigs showed lower (P &lt; 0.05) feed intake. A 2-way interaction (N levels × LPS challenge, P &lt; 0.05) was observed for NI, NEX and ND, with a clear dose-response (P &lt; 0.05). LPS-challenged pigs showed lower NI and ND at 2.09% N and 1.69 to 3.97% N (P &lt; 0.05), respectively, and higher NEX at 3.23% N (P &lt; 0.05). The parameters obtained by a nonlinear model (N maintenance requirement, NMR and theoretical maximum N deposition, NDmaxT) were 152.9 and 197.1 mg/BWkg  0.75/d for NMR, and 3,524.7 and 2,077.8 mg/BWkg  0.75/d for NDmaxT, for control and LPS-challenged pigs, respectively. The estimated digestible Lys requirements were 1,994.83 and 949.16 mg/BWkg  0.75/d for control and LPS-challenged pigs, respectively. The daily digestible Lys intakes required to achieve 0.68 and 0.54 times the NRmaxT value were 18.12 and 8.62 g/d, respectively, and the optimal dietary digestible Lys concentration may change depending on the feed intake levels. Based on the derived model parameters obtained in the N balance trial with lower cost and time, it was possible to differentiate the digestible Lys requirement for swine under challenging conditions.

Numerous plants are reported to have ethno-therapeutic properties; among these plants are the leaves of Moringa oleifera and Azadirachta indica used for the treatment of protozoan infections. Forty grower rabbits at approximately 70 days old were used to determine the prophylactic anti-trypanosomal effects of the dry leaf meals of Moringa oleifera (MLM) and Azadirachta indica (NLM). The rabbits were placed into eight groups of five animals each in a completely randomized design, with mean live weights of 1.2 Kg. The rabbits were allotted to four diets (D1, D2, D3 and D4) and two levels of inoculation (inoculated and uninoculated rabbits) in a 4×2 factorial arrangement of a Completely Randomised Design. Parameters monitored were performance, serum biochemistry and rectal temperature. The parasitaemia were presented as line graph for the infected rabbits. The percent mortality of the groups was evaluated and no mortality was observed for rabbits fed D4. No significant differences (P>0.05) were observed between treatments for growth rate, feed intake and feed conversion, except rectal temperature and total protein (P<0.05) in serum biochemistry. Rabbits that were uninfected with trypanosomes had (P<0.05) lower total protein than the infected animals except T2. It was concluded that only the 1% MLM had prophylactic anti- trypanosomal effect on serum total protein and mortality amelioration of T. b. brucei infected rabbits when administered alone and a combination of both MLM and NLM prevented  pyrexia and mortality.     De nombreuses plantes auraient des propriétés ethno-thérapeutiques ; parmi ces plantes figurent les feuilles de Moringaoleifera et d'Azadirachtaindica utilisées pour le traitement des infections protozoaires. Quarante lapins de culture à environ 70 jours ont été employés pour déterminer les effets anti-trypanosomal prophylactiques des repas secs de feuille de Moringaoleifera (le 'MLM') et d'Azadirachtaindica (le 'NLM'). Les lapins ont été placés en huit groupes de cinq animaux chacun dans une conception complètement randomisée, avec des poids vivants moyen de 1,2 kg. Les lapins ont été attribués à quatre régimes (D1, D2, D3 et D4) et deux niveaux d'inoculation (lapins inoculés et non ininoculés) dans un arrangement factorial de 4×2 d'un Désigne complètement randomisé. Les paramètres surveillés étaient la performance, la biochimie sérique et la température rectale. La parasitémie a été présentée comme graphique linéaire pour les lapins infectés. La mortalité en pourcentage des groupes a été évaluée et aucune mortalité n'a été observée chez les lapins nourris au D4. Aucune différence significative (P>0,05) n'a été observée entre les traitements pour le taux de croissance, l'apport alimentaire et la conversion des aliments pour animaux, à l'exception de la température rectale et de la protéine totale (P<0,05) dans la biochimie sérique. Les lapins qui n'étaient pas infectés par les trypanosomes avaient (P<0,05) moins de protéines totales que les animaux infectés, à l'exception du T2. On l'a conclu que seulement le MLM de 1% a eu l'effet anti-trypanosomal prophylactique sur la protéine totale de sérum et l'amélioration de mortalité des lapins infectés de T.b. brucei une fois administrés seuls et une combinaison de MLM et de NLM a empêché la pyrexie et la mortalité.

Over Time

Background: Comparability of laboratory measures over time is important for studies of disease prevalence and progression. While a small amount of bias may seem negligible on an individual level, it can result in substantial misclassification of disease in the population. We conducted a calibration study of important biomarkers across five study visits (25 years) in ARIC. Methods: We re-measured 15 analytes in 200 blood samples to calibrate original measurements at each time point using Bland-Altman plots and Deming regression. We also assessed the impact of calibration on the prevalence of chronic kidney disease (CKD), defined by estimated glomerular filtration rate using creatinine (eGFRcr), and on trends over time. Results: Assays in samples frozen 12-27 years were highly correlated with original values (median r=0.95) after removing outliers (median 4% of values). The range of bias (% difference in means) across visits for each original analyte compared to its reference were: creatinine: 13-49%; uric acid: 3-24%; C-reactive protein: 3-9%; total cholesterol: 1-6%; high density lipoprotein cholesterol: 4-8% (but new methods differed); low density lipoprotein cholesterol: 1-5%; triglycerides: 2-4%; glucose: 1-4%; N-terminal prohormone of brain natriuretic peptide: 2-12%; high sensitivity cardiac troponin T: 1-9%; alanine transaminase (ALT): 21%; aspartate transaminase (AST): 17%; gamma glutamyl transpeptidase: 0.2%; ß2-microglobulin: 1%; beta-trace protein: 13%. Four analytes met calibration criteria: creatinine, uric acid, ALT and AST. The impact on CKD prevalence was substantial and similar to previous statistical calibration (22% uncalibrated, 1.9% previously and 1.3% current laboratory calibration). Trends in eGFRcr over time were better aligned after calibration ( Figure ). Conclusions: Repeat assay of samples shows high correlation with original values. Calibration enables application of absolute cutoffs (required for defining CKD and other conditions) and improves longitudinal analyses.

<b><i>Introduction:</i></b> It is not clear whether serum uric acid (SUA) levels and their changes over time are associated with the risk of stroke. A 7-year prospective cohort study in northwest China was conducted to analyze effects of SUA and their changes on the risk of stroke. <b><i>Methods:</i></b> A total of 23,262 individuals without cardiovascular disease in the Jinchang cohort were followed up for an average of 5.26 years. The Cox proportional hazard model was used to estimate the hazard ratios (HRs) and 95% confidence interval (95% CI) of stroke incidence to SUA and relative changes in SUA. Sensitivity analysis was performed after controlling the effect of renal insufficiency. <b><i>Results:</i></b> Baseline SUA and relative changes in SUA were positively correlated with the incidence of stroke in both males and females (<i>p</i> for overall association &#x3c;0.0001). Stroke risk increased by 4.6% per 10% increase in the relative change of SUA (HR = 1.046, 95% CI, 1.007–1.086). The fully adjusted regression analysis demonstrated that only the large gain (&#x3e;30%) in SUA was associated with an increased risk of stroke by 36.5% (95% CI, 1.8–83.0%), compared with the reference group (participants within ±10% changes in SUA). The same trend was observed in people with normal baseline SUA. In the unadjusted model, the risk of stroke associated with elevated SUA was significantly higher in the hyperuricemia group than in the normal SUA group. <b><i>Conclusion:</i></b> High initial SUA concentration and an increase in SUA concentration over time would increase the risk of stroke, and this means that there is no safe increase in SUA.
