As one of the most important mineral nutrient elements, potassium (K(+)) participates in many plant physiological processes and determines the yield and quality of crop production. In this review, we summarize K(+) signaling processes and K(+) transport regulation in higher plants, especially in plant responses to K(+)-deficiency stress. Plants perceive external K(+) fluctuations and generate t...
The essential vitamin biotin is a covalent and tenaciously attached prosthetic group in several carboxylases that play important roles in the regulation of energy metabolism. Here we describe increased acetyl-CoA levels and mitochondrial hyperacetylation as downstream metabolic effects of biotin deficiency. Upregulated mitochondrial acetylation sites correlate with the cellular deficiency of th...
background low-cost anaerobic sequencing batch reactor (asbr), which is widely used for controlling high-organic wastewater, is an effective method to remove chemical oxygen demand (cod). objectives the main objectives was evaluating the feasibility of using asbr in the treatment of synthetic dairy wastewater, determining its removal efficiency, and assessing the effect of temperature on operat...
Niacin, also known as vitamin B3, is required for the synthesis of coenzymes, nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Niacin binds with G protein-coupled receptor (GPR) 109A on cutaneous Langerhans cells and causes vasodilation with flushing in head and neck area. Niacin deficiency due to excessive alcohol consumption, certain drugs or ina...
Saccharomyces cerevisiae (baker's yeast) is an excellent model for understanding fundamental biological mechanisms that are conserved in Nature and that have an impact on human disease. The metal iron is a redox-active cofactor that plays critical biochemical roles in a broad range of functions, including oxygen transport, mitochondrial oxidative phosphorylation, chromatin remodelling, intermed...
High voltage spinel LiNi(0.5)Mn(1.5)O(4) is a very promising cathode material for lithium ion batteries that can be used to power hybrid electrical vehicles (HEVs). Through careful control of the cooling rate after high temperature calcination, LiNi(0.5)Mn(1.5)O(4) spinels with different disordered phase and/or Mn(3+) contents have been synthesized. It is revealed that during the slow cooling p...
