Eimeria Maxima

SUMMARYThe effects of Eimeria maxima or restricted pair-feeding on weight gain, plasma concentrations of protein, glucose, free fatty acids (FFA) and uric acid and liver glycogen were compared in immature fowl. Food intake/kg body weight and weight gain decreased during the acute phase of infection (days 5–7) while weight loss was prolonged for an extra day compared with pair-fed birds. During recovery, food intake/kg body weight of infected birds was greater than that of non-infected controls but there was no evidence for an increase in growth rate compared with controls when body weight was considered. Growth rate of pair-fed birds was greater than that of infected birds during recovery, indicating their better use of ingested food. Liver glycogen and plasma protein concentration were decreased during the acute phase of infection but the concentrations of plasma glucose, free fatty acid (FFA) and uric acid were not affected. In pair-fed birds liver glycogen was depleted, concentrations of plasma glucose and uric acid decreased and FFA increased, and these changes persisted for the remainder of the experiment. The findings are similar to those in birds whose food has been withheld and were probably due to the pattern of food intake imposed by the experimental protocol. It is concluded that the metabolic differences between infected and pair-fed birds are of doubtful significance.

Cardiovascular Rhythms

Irregular timing of food intake increases hypertension and cardiometabolic disease risk. A chronic high fat diet (HFD) also disrupts circadian rhythms. We hypothesized that active period time restricted feeding (TRF) during the last 2 weeks in mice on a chronic HFD will improve blood pressure rhythm, diurnal variation of circulating plasma factors, and vascular metabolism. Mice (male 8-week old, C57BL/6J) were fed a normal diet (ND; 10% fat) or HFD (45% fat) for 20 weeks ad libitum. For the final 2 weeks, half of the HFD mice were subjected to TRF. Mean arterial pressure (MAP), heart rate (HR), and locomotor activity were assessed by telemetry. TRF significantly increased the active-inactive period difference in MAP and HR in in mice fed a HFD (ΔMAP: ND: 16±0.7 mmHg, HFD: 15±0.8 mmHg, HFD+TRF: 18±0.9 mmHg, n=6-8, p=0.01; ΔHR: ND: 68±5.1 bpm, HFD: 69±6.5 bpm, HFD+TRF: 113±7.9 bpm, n=6-8, p<0.01). Diurnal changes in locomotor activity are not different between groups. At the end of the study, plasma was collected at 4 hour intervals over a 24 hour period (ZT0 at 7AM; ZT12 at 7PM). Circulating levels of liver-derived mediators β-hydroxybutyrate (βHB) and insulin-like growth factor-1 (IGF-1) showed significant differences due to diet but not TRF (βHB, ZT21: ND: 0.16±0.01 mM, HFD: 0.20±0.02 mM, HFD+TRF: 0.19±0.01 mM, n=5-6, p=0.02; IGF-1, ZT5: ND: 232±18 ng/mL, HFD: 292±34 ng/mL , HFD+TRF: 371±14 ng/mL, n=5-6, p<0.01). Plasma leptin was significantly higher in mice on HFD and reduced by TRF at ZT12 (ND: 5.3±1.3 ng/mL, HFD: 22.5±2.9 ng/mL, HFD+TRF: 10.3±3.5ng/mL, n=5-6, p<0.01) and ZT17 (ND: 6.7±1.1 ng/mL, HFD: 32.5±3.0 ng/mL, HFD+TRF: 25.0±1.3 ng/mL, n=5-6, p<0.01). Plasma adiponectin was unchanged between all groups. TRF in HFD mice increased NAD + , important for metabolism, in renal vessels at ZT17 (HFD: 0.10±0.02 pmol/μg; HFD+TRF: 0.19±0.03 pmol/μg; n=5, p=0.03). Aortic NAD + at ZT1 was not affected by TRF in HFD mice (HFD: 1.83±0.35 pmol/μg, HFD+TRF: 1.35±0.35 pmol/μg, n=4, p=0.37). Our results indicate that TRF in mice on HFD increases the active-inactive period difference in MAP and HR and alters plasma metabolites, suggesting the timing of food intake on a chronic HFD improves cardiovascular rhythms with increased renal vascular metabolism and reduced leptin levels.

Food intake biomarkers can be critical tools that can be used to objectively assess dietary exposure for both epidemiological and clinical nutrition studies. While an accurate estimation of food intake is essential to unravel associations between the intake and specific health conditions, random and systematic errors affect self-reported assessments. This study aimed to clarify how habitual food intake influences the circulating plasma metabolome in a free-living Japanese regional population and to identify potential food intake biomarkers. To achieve this aim, we conducted a cross-sectional analysis as part of a large cohort study. From a baseline survey of the Tsuruoka Metabolome Cohort Study, 7,012 eligible male and female participants aged 40–69 years were chosen for this study. All data on patients’ health status and dietary intake were assessed via a food frequency questionnaire, and plasma samples were obtained during an annual physical examination. Ninety-four charged plasma metabolites were measured using capillary electrophoresis mass spectrometry, by a non-targeted approach. Statistical analysis was performed using partial-least-square regression. A total of 21 plasma metabolites were likely to be associated with long-term food intake of nine food groups. In particular, the influential compounds in each food group were hydroxyproline for meat, trimethylamine-N-oxide for fish, choline for eggs, galactarate for dairy, cystine and betaine for soy products, threonate and galactarate for carotenoid-rich vegetables, proline betaine for fruits, quinate and trigonelline for coffee, and pipecolate for alcohol, and these were considered as prominent food intake markers in Japanese eating habits. A set of circulating plasma metabolites was identified as potential food intake biomarkers in the Japanese community-dwelling population. These results will open the way for the application of new reliable dietary assessment tools not by self-reported measurements but through objective quantification of biofluids

AbstractLeptin is thought to act on the central nervous system as an important regulator of food intake and body weight in mice. To examine the actions of leptin in sheep, we injected recombinant mouse leptin into the lateral cerebral ventricle of ewes. Six ewes were intracerebroventricularly cannulated and given free access to forage and water. The ewes were injected with phosphate-buffered saline (PBS) as a vehicle for 5 days through the cannula and then with PBS + leptin for 7 days consecutively. Although food intake and body weight did not change during PBS injection, the administration of leptin decreased food intake and body weight. Plasma glucose levels decreased and plasma non-esterified fatty acid levels increased on the last few days of leptin administration. Approximately 2 weeks after normal food intake was recovered, the amount of diet was individually reduced in accordance with the recorded food intake during the leptin administration in each sheep. During food restriction, body weight and plasma metabolite concentrations were similarly changed as during the leptin-administration period. These results indicate that leptin decreases food intake in sheep. Moreover, it is likely that the changes in body weight and plasma metabolites were mainly induced by the suppression of food intake during leptin injection.
