A total of 660 one-day-old Ross 308 broiler chicks were randomly distributed into eleven dietary treatments. Treatments included a maize-soybean meal-based diet with recommended calcium (Ca) and non-phytate phosphorus (nPP) (positive control; PC), an nPP-deficient diet (negative control; NC), NC diets supplemented with different levels of phytase (0, 500, 1,000, 2,000, 3,000, 4,000, 5,000, and 6,000 FTU/kg), a NC diet plus 0.15% myo-inositol, and a NC diet with reduced Ca level (Ca to nPP ratio same as PC)...

The intense genetic selection for rapid growth in broilers has resulted in an increase in voluntary feed intake and growth rate, accompanied by increased fat deposition in adipose tissue depots throughout the body. Adipose tissue expansion is a result of the formation of adipocytes (several processes collectively referred to as adipogenesis) and cellular accumulation of triacylglycerols inside lipid droplets. In mammals, different anatomical depots are metabolically distinct. The molecular and cellular mechanisms underlying adipose tissue development have been characterized in mammalian models, whereas information in avian species is scarce...

Because of consumers' preferences and also due to changes in production systems, the importance of pure breeds has increased again. There are a lot of differences among breeds which have been studied extensively, however, the differences during the incubation period are not yet fully known. Therefore, the present study was conducted to evaluate the composition of the egg parts, absorption of nutrients, and development of embryos from different genotypes. A total of 354 fresh hatching eggs were obtained from one hybrid (Lohman White, LW) and two pure breeds (Denizli and Gerze)...

The airlift external circulation membrane bioreactors (AEC-MBRs) have been attracting attentions due to their capabilities of nutrient removal with lower energy demand and smaller footprint. The gap between laboratory study and full-scale AEC-MBRs regarding hydrodynamics needs to be addressed. In this study, impacts of seven design variables and cyclic aeration modes on hydrodynamics were studied for the scale-up of AEC-MBRs with computational fluid dynamics modelling. The results demonstrated that shear stress on membranes was 14...

Incretin and insulin responses to nutrient loads are suppressed in persons with diabetes, resulting in decreased glycemic control. Whereas agents including sulfonylureas and Dipeptidyl peptidase-4 inhibitors (DPP4i) partially reverse these effects and provide therapeutic benefit, their modes of action limit efficacy. Because somatostatin (SST) has been shown to suppress both insulin and GLP-1 secretion through the Gi-coupled SST receptor 5 (SSTR5) isoform in vitro, antagonism of SSTR5 may improve glycemic control via intervention in both pathways...

Incretin hormones play an important role in the regulation of food intake and glucose homeostasis. Glucagon-like peptide-1 (GLP-1) secreting cells have been demonstrated to be electrically excitable and to fire action potentials (APs) with increased frequency in response to nutrient exposure. However, nutrients can also be metabolised or activate G-protein-coupled receptors, thus potentially stimulate GLP-1 secretion independent of their effects on the plasma membrane potential. Here we used channelrhodopsins to manipulate the membrane potential of GLUTag cells, a well established model of GLP-1 secreting enteroendocrine L-cells...

Fluorosis, caused by ingestion of excess fluoride, is endemic in at least 25 countries across the globe, China and India being the worst affected among them. Dental, skeletal and non-skeletal are the major types of fluorosis affecting millions of people in these countries. A number of genetic epidemiological studies carried out by investigators have shown the evidence for association between genetic polymorphisms in candidate genes and differences in the susceptibility pattern of different types of fluorosis among individuals living in the same community and having the same environmental exposure...

The objective of this study was to determine the concentrations of Cu, Cd, Pb, Mn, Cr, Co, Ni, Zn, and Hg in the white and fruit parts of commercially available yogurts (n = 30) from Nitra markets (Slovak Republic). The results were correlated to determine their relationships. Three yogurt fruit flavors were chosen and tested, strawberry (n = 10), blueberry (n = 10), and cherry (n = 10). The elements were analyzed using atomic absorption spectrophotometry. Higher concentrations of toxic elements, such as Cd and Pb, were found in the fruit parts of the yogurt, and in some cases, the tolerable limit was exceeded...

To provide a comprehensive analysis of the literature examining the pros and cons of protein supplementation, various articles on protein supplementation were obtained from Google Scholar, PubMed, and National Center for Biotechnology Information. Over the past few years, protein supplementation has become commonplace for gym-goers as well as for the public. A large segment of the general population relies on protein supplementation for meal replacement, weight reduction, and purported health benefits. These protein supplements have varying pros and cons associated with them, which are often overlooked by the public...

Lung cancer is the leading cause of death by cancer, and is a major sanitary concern worldwide. Some nutrients, such as ω-9 fatty acids, have been proposed as anticancer agents. Thus, an olein-enriched diet was assayed in a murine model of lung adenocarcinoma (LAC-1) to evaluate neoplastic and paraneoplastic evolution in BALB/c mice. The organic assimilation of dietary fatty acids was confirmed in liver by gas chromatography. This experimental oleic acid-containing diet increased animal survival and tumour latency (analysed by the Kaplan-Meier method), improving neoplastic evolution and general status, with weak effects on the paraneoplastic syndrome (thymus atrophy, splenomegaly, splenocyte response to mitogen, blood anaemia, and leucocytosis)...

Marginal agricultural land provides opportunities to diversify landscapes by producing biomass for biofuel, and through floral provisioning that enhances arthropod-mediated ecosystem service delivery. We examined the effects of local spatial context (adjacent to woodland or agriculture) and irrigation (irrigation or no irrigation) on wildflower bloom and visitation by arthropods in a biofeedstocks-wildflower habitat buffer design. Twenty habitat buffer plots were established containing a subplot of Napier grass (Pennisetum perpureum Schumach) for biofeedstock, three commercial wildflower mix subplots, and a control subplot containing spontaneous weeds...

The normal retinal development is interrupted by preterm birth and a retinopathy of prematurity (ROP) may develop as its consequence. ROP is characterized by aberrant vessel formation in the retina as a response to multiple risk factors influencing the process of retinal angiogenesis. Insulin-like growth factor I (IGF-1) and vascular endothelial growth factor (VEGF) play an important role in the process of normal retinal vascularization. Insufficient nutrition during the first 4 postnatal weeks results in low serum levels of IGF-1, which is essential for correct retinal vessels formation, ensuring survival of the newly formed endothelial cells...

The potentially metabolically active components within the prokaryotic assemblages inhabiting the Antarctic Lake Limnopolar (Byers Peninsula, Maritime Antarctica) were investigated by a polyphasic approach which included culture-dependent and culture-independent methods (based on RNA molecules). Results support previous observations on the Proteobacteria and Bacteroidetes dominance, followed by Actinobacteria, in Antarctic lakes. In particular, Alpha-, Betaproteobacteria and Bacteroidetes were mainly detected by CARD-FISH and cDNA cloning, whereas Gammaproteobacteria and Actinobacteria dominated within the cultivable fraction...

Habitat homogenization, nutrient enrichment and loss of biodiversity are broadly recognized as the consequences of human activity in aquatic systems. Diatoms (Bacillariophyceae) are frequently used in aquatic environmental assessment and impact monitoring, but in unique habitats dominated by endemic taxa, traditional approaches may not be appropriate. We examined the impacts of long term anthropogenic impacts upon the littoral episammic diatom community around the town of Soroako, located on Lake Matano, an ancient tropical lake...
