The study's objectives include identifying the clinical prevalence, antibiogram profile, and Gompertz growth kinetics of MRSE treated with synthetically created nanoparticles of rosin obtained from . A total of 64 of 200 clinical isolates of (32% of the total) displayed sensitivity (40.

An updated review on behavior of domestic quail with reference to the negative effect of heat stress.

Japanese quail originated from the wildlife environment and was first domesticated in Japan in 1595. Japanese quail has widely distributed in various parts of the world. This bird is characterized by its rapid growth rate, high rate of egg production, much lower space requirements, small size, good reproductive potential, short life cycle, resistance to diseases, early sexual maturity (from 39 to 50days), better laying ability and shorter time of hatching compared with the different species of poultry.

Nanominerals: Fabrication Methods, Benefits and Hazards, and Their Applications in Ruminants with Special Reference to Selenium and Zinc Nanoparticles.

Nanotechnology is one of the major advanced technologies applied in different fields, including agriculture, livestock, medicine, and food sectors. Nanomaterials can help maintain the sustainability of the livestock sector through improving quantitative and qualitative production of safe, healthy, and functional animal products. Given the diverse nanotechnology applications in the animal nutrition field, the use of nanomaterials opens the horizon of opportunities for enhancing feed utilization and efficiency in animal production.

Role of Yeast and Yeast-Derived Products as Feed Additives in Broiler Nutrition.

Antibiotic resistance is looming problem in broiler production globally and there has been an increasing interest to look for sustainable alternatives to antibiotics. Yeast and its derived products are recognized as potential feed additives because of their beneficial impacts on poultry. Particularly, yeast exhibited positive effects on the humoral immunity by increasing serum immunoglobulin (Ig) A levels.

Reconsidering betaine as a natural anti-heat stress agent in poultry industry: a review.

Betaine is found ubiquitously in plants, animals, microorganisms, and rich dietary sources including seafood, spinach, and wheat bran. The chief physiological role of betaine is to function as a methyl donor and an osmolyte. Betaine also acts as an osmolyte, to maintain the avian's cellular water and ion balance to improve the avian's capacity against heat stress via preventing dehydration and osmotic inactivation.

Cadmium chloride inhibits lactate gluconeogenesis in mouse renal proximal tubules: An in vitro metabolomic approach with (13)C NMR.

Using isolated mouse renal proximal tubules incubated with lactate as substrate, we have found that the addition of 1-50 μM cadmium chloride (CdCl2) caused a concentration-dependent decrease in lactate utilization, in glucose production and in the cellular level of ATP, coenzyme A, acetyl-coenzyme A and glutathione (reduced and oxidized forms). Combining enzymatic and (13)C NMR measurements in a cellular metabolomic approach, we have shown that, in the presence of 10 μM CdCl2, fluxes through the key-enzymes of gluconeogenesis, phosphoenolpyruvate carboxykinase and glucose-6-phosphatase were greatly depressed by cadmium. This was accompanied by a reduction in fluxes through the enzymes of the tricarboxylic acid cycle.

Cadmium chloride inhibits lactate gluconeogenesis in isolated human renal proximal tubules: a cellular metabolomic approach with 13C-NMR.

As part of a study on cadmium nephrotoxicity, we studied the effect of cadmium chloride (CdCl2) in isolated human renal proximal tubules metabolizing the physiological substrate lactate. Dose-effect experiments showed that 10-500 μM CdCl2 reduced lactate removal, glucose production and the cellular levels of ATP, coenzyme A, acetyl-coenzyme A and of reduced glutathione in a dose-dependent manner. After incubation with 5 mM L: -[1-(13)C]-, or L: -[2-(13)C]-, or L: -[3-(13)C] lactate or 5 mM L: -lactate plus 25 mM NaH(13)CO3 as substrates, substrate utilization and product formation were measured by both enzymatic and carbon 13 NMR methods.

Protocols and applications of cellular metabolomics in safety studies using precision-cut tissue slices and carbon 13 NMR.

Numerous xenobiotics are toxic to human and animal cells by interacting with their metabolism, but the precise metabolic step affected and the biochemical mechanism behind such a toxicity often remain unknown. In an attempt to reduce the ignorance in this field, we have developed a new approach called cellular metabolomics. This approach, developed in vitro, provides a panoramic view not only of the pathways involved in the metabolism of physiologic substrates of any normal or pathologic human or animal cell but also of the beneficial and adverse effects of xenobiotics on these metabolic pathways.

Uranyl nitrate inhibits lactate gluconeogenesis in isolated human and mouse renal proximal tubules: a 13C-NMR study.

As part of a study on uranium nephrotoxicity, we investigated the effect of uranyl nitrate in isolated human and mouse kidney cortex tubules metabolizing the physiological substrate lactate. In the millimolar range, uranyl nitrate reduced lactate removal and gluconeogenesis and the cellular ATP level in a dose-dependent fashion. After incubation in phosphate-free Krebs-Henseleit medium with 5 mM L-[1-13C]-, or L-[2-13C]-, or L-[3-13C]lactate, substrate utilization and product formation were measured by enzymatic and NMR spectroscopic methods.
