Polycystic ovary syndrome (PCOS) is a common endocrine abnormality among reproductive-aged women. This study aimed to investigate the relevance of major nutrient patterns and PCOS. Methods: This age-body mass index (BMI) matched case-control study was conducted among 216 women with and without PCOS. The validated 178-items food frequency questionnaire (FFQ) was used for driving nutrient pattern...

Litterfall contributes to the development of forest soils, since it undergoes a decomposition process that generates release nutrients ontothe soil. Therefore, objective this study was evaluate annual litterfall production, return (Ca, Mg, K and P) thenutrient use efficiency (NUE) in three ecosystems northeastern Mexico. quantified on monthly basis from january todecember 2020 at sites: Site 1 ...

Objectives. The objective was to determine the fracture and cyclic fatigue properties of composite–dentin beams bonded with a self-etching adhesive in four-point bend. Methods. Beams of rectangular cross-section were shaped to a size of ∼0.87mm×0.87mm×10mm and placed in a four-point bending apparatus, with the loading points 1.8 and 7.2mm apart, with the interface centered between the inner rol...

The therapeutic use of medicinal plants such as Echinacea, ginseng and St. John’s wort has gained widespread acceptance in North America in the last two decades. Aeroponic cultivation of medicinal plants have shown great potential for producing root yields that are cleaner, more uniform and faster maturing than can be obtained using conventional soil-based methods. Two pilot-scale commercial A-...

MOTIVATION The appropriate modulation of the stress response to variable environmental conditions is necessary to maintain sustained viability in Saccharomyces cerevisiae. Particularly, controlling the abundance of proteins that may have detrimental effects on cell growth is crucial for rapid recovery from stress-induced quiescence. RESULTS Prompted by qualitative modeling of the nutrient sta...

The aim of this study was to investigate the impact some pesticides on plant growth promoting activities Rhizobium spp. isolated from Sesbania bispinosa. Sustainability and environmental safety agricultural production relies eco-friendly approaches like use biofertilizers, biopesticides crop residue return. promoters (PGP) emphasize need for further strengthening research their in modern agricu...

The lactating dairy cow responds to dietary changes according to the nutrients provided and her propensity to produce milk. The allocation of nutrient use to milk production or body gain is generally termed ‘partition’ and has been shown to be a function of both the animal and its diet. As feed intake is increased, the lactating cow responds with progressively smaller increments of increased mi...

Some motile phytoplankton have the capability to exploit deep sources of nutrients in a vertical migration cycle: photosynthesis in the near-surface layer, transit to depth, uptake of the limiting nutrient and transit back to the surface layer. If all four steps can be completed within 24 h, then migrations can be synchronized to the day/night cycle to maximize photosynthetic efficiency. Altern...
