Understanding of microbial communities inhabiting cattle vaginal tract may lead to a better comprehension bovine physiology and reproductive health being great economic interest. Up date, studies involving microbiota are focused on the gastrointestinal tract, little is known about microbiota. This study aimed investigate microbiome in Nellore cattle, heifers cows, pregnant non-pregnant, using culture independent approach. The main bacterial phyla found were Firmicutes (~40–50%),...
Here, we describe the metagenome and functional composition of a microbial community in historically metal-contaminated tropical freshwater stream sediment. The sediment was collected from Mina Stream located Iron Quadrangle (Brazil), one world’s largest mining regions. Environmental DNA extracted sequenced using SOLiD technology, total 7.9 Gbp produced. A taxonomic profile that obtained by comparison to Greengenes database revealed complex with dominance Proteobacteria Parvarcheota. Contigs...
Bacteria from aquatic ecosystems significantly contribute to biogeochemical cycles, but details of their community structure in tropical mining-impacted environments remain unexplored. In this study, we analyzed a bacterial circumneutral-pH stream sediment by 16S rRNA and shotgun deep sequencing. Carrapatos sediment, which has been exposed metal stress due gold iron mining (21 [g Fe]/kg), revealed diverse community, with predominance Proteobacteria (39.4%), Bacteroidetes (12.2%),...
The pathogenesis of nonalcoholic fatty liver disease (NAFLD) is not fully understood, and experimental models are an alternative to study this issue. We investigated the effects a simple carbohydrate-rich diet on development obesity-related NAFLD impact physical training metabolic abnormalities associated with disorder. Sixty Wistar rats were randomly separated into control groups, which fed sucrose-enriched (18% carbohydrates) standard diet, respectively. At end each period (5, 10, 20, 30...
Hispaniola, which is shared by Haiti and the Dominican Republic, remains last island in Caribbean that still endemic for malaria, with bearing highest caseload. Few studies have examined ecology of malaria vectors Haiti. Five species Anopheles been described on island, but exophilic albimanus ( An. ) considered primary vector Households recruited a case–control study profiling risk factors symptomatic Plasmodium falciparum P. infections were approached to participate an entomological study....
To assess the role of central dopamine on metabolic rate, heat balance and running performance, 2.0 microL 5 x 10(-3)M solution (DA) or 0.15M NaCl (SAL) was intracerebroventricularly injected in Wistar rats 1 min before a motor-driven treadmill, according to graded exercise protocol, until fatigue. Oxygen consumption (VO(2)) body temperature (T(b)) were recorded at rest, during exercise, after 30 recovery. DA induced marked increase workload (approximately 45%, p<0.05). At fatigue point,...
To investigate the influence of angiotensin II (Ang II) AT1 receptors blockade on central fatigue induced by brain content serotonin (5-HT) and dopamine (DA) during exercise.Losartan (Los) was intracerebroventricularly injected in rats before running until (n = 6 per group). At fatigue, brains were quickly removed for measurement 5-HT, 5-hydroxyindoleacetic acid (5-HIAA), DA, 3,4-dihydroxyphenylacetic high-pressure liquid chromatography preoptic area, hypothalamus, hippocampus, frontal...
Instagram (IG) reaches millions of people, sharing personal content and all kinds information, including those related to exercise health. However, the scientific quality posted information is questionable. Thus, this study aimed analyze whether health by popular Brazilian IG influencers has technical-scientific accuracy. A account was created identify profiles. The inclusion criteria accounts were: (1) having 50% shared posts topics about health, such as nutrition, wellness, medicine, or...
Summary The effects of increased brain availability l ‐arginine ( ‐arg), a precursor for nitric oxide synthesis, on core body temperature T ) and cutaneous heat loss were evaluated in running rats. One week prior to the experiments, adult male Wistar rats received following implants: chronic guide cannula lateral cerebral ventricle sensor abdominal cavity. On day assigned receive 2‐ μ L intracerebroventricular injection either NaCl (0.15 mol/L) or ‐arg solution (0.825, 1.65 3.30 mol/L); tail...
Bacteriophages represent an alternative solution to control bacterial infections. When interacting, bacteria and phage can evolve, this relationship is described as antagonistic coevolution, a pattern that does not fit all models. In work, the model consisted of microcosm
The effect of central angiotensin AT1-receptor blockade on thermoregulation in rats during exercise a treadmill (18 m/min, 5% inclination) was investigated. Core (Tb) and skin tail temperatures were measured while they exercising until fatigue after injection 2 microl losartan (Los; 20 nmol, n = 4; 30 60 7), an II antagonist, or 0.15 mol/l NaCl (Sal; 15) into the right lateral cerebral ventricle. Body heat rate (BHR), storage rate, threshold Tb for vasodilation (TTbV), time to fatigue,...
We investigated the response of microbial community to changes in H2S loading rate a microaerated desulphurisation system treating biogas from vinasse methanisation. removal efficiency was high, and both COD DO seemed be important parameters biomass activity. DGGE analysis retrieved sequences sulphide-oxidising bacteria (SOB), such as Thioalkalimicrobium sp. Deep sequencing revealed that complex remained constant throughout experiment. Most belonged Firmicutes Proteobacteria, and, lesser...
We assessed the contribution of paraventricular nucleus (PVN) in heat stress-mediated changes sympathetic nerve activity and blood flow redistribution from core to skin surface. Renal (RSNA), mean arterial pressure (MAP), heart rate (HR), body tail temperatures were recorded anesthetized rats after bilateral microinjection cerebrospinal fluid (CSF), lidocaine or NG-monomethyl-L-arginine (l-NMMA) into PVN during stress. Heat stress was induced by a graded increase temperature heating pad for...
The performance of a demonstration-scale anaerobic reactor treating food waste was evaluated with an emphasis on microbial response to increasing organic loading rates (OLRs). exhibited stable in terms methane yield at OLR ranging from 1.0 2.4 kg VS L-1 day-1 (phases I and II), compared that phase III (OLR: 1.0-1.5 day-1) when the greater acidity. Deep sequencing analysis revealed shifts composition each operational phase. phyla Firmicutes Bacteroidetes were favoured, whereas abundance...
Individuals with systemic arterial hypertension have a higher risk of heat-related complications. Thus, the aim this study was to examine thermoregulatory responses hypertensive subjects during recovery from moderate-intensity exercise performed in heat. A total eight essential (H) and normotensive (N) male (age=46.5±1.3 45.6±1.4 years, body mass index=25.8±0.8 25.6±0.6 kg/m2, mean pressure=98.0±2.8 86.0±2.3 mmHg, respectively) rested for 30 min, 1 h treadmill at 50% maximal oxygen...
