What is Refeeding Syndrome?
Discussion Anorexia nervosa is an eating disorder with an intense fear of being overweight (i.e. distorted body image), and self-starvation and excessive weight loss. It is more common in women (1.2%) than men (0.2%) but can be seen in both genders. Risk factors include high-intelligence, perfectionism/inflexibility, anxiety, activities where thinner body types are expected (e.g. dancer, diver, gymnast, long-distance runner, volleyball player, etc.) Other eating disorders include bulimia nervosa (i.e. cycles of binge eating and then purging), binge eating disorder (i.e. purging), orthorexia (i.e. obsessions with healthful ...

Metagenomic analysis reveals global-scale patterns of ocean nutrient limitation
Nutrient supply regulates the activity of phytoplankton, but the global biogeography of nutrient limitation and co-limitation is poorly understood. Prochlorococcus adapt to local environments by gene gains and losses, and we used genomic changes as an indicator of adaptation to nutrient stress. We collected metagenomes from all major ocean regions as part of the Global Ocean Ship-based Hydrographic Investigations Program (Bio-GO-SHIP) and quantified shifts in genes involved in nitrogen, phosphorus, and iron assimilation. We found regional transitions in stress type and severity as well as widespread co-stress. Prochlorococ...

(Osaka University) Osaka University researchers have developed a single-crystal cobalt phosphide nanorod catalyst for the reductive amination of carbonyl compounds to primary amines. The nanorod catalyst performed better than conventional catalysts, was stable in air, and was effective under mild conditions. Additionally, it could be reused multiple times without loss of activity. It is hoped that the nanorod catalyst will provide a green and sustainable alternative for the synthesis of valuable products such as pharmaceuticals. (Source: EurekAlert! - Biology)

Spontaneous photocurrent was observed along the polar direction and was absent in the direction perpendicular to it. The observed spontaneous photocurrent was explained by a quantum-mechanical shift current that reflects the geometrical and topological electronic nature of this emerg...

In this study, we explore long-standing observations that microbes increase the production of redox-active antibiotics under phosphorus limitation. The availability of phosphorus, a nutrient required by all life on Earth and essential for agriculture, can be controlled by adsorption to and release from iron minerals by means of redox cycling. Using phenazine antibiotic production by pseudomonads as a case study, we show that phenazines are regulated by phosphorus, solubilize phosphorus through reductive dissolution of iron oxides in the lab and field, and increase phosphorus-limited microbial growth. Phenazines are just on...

Black phosphorus composites with engineered interfaces for high-rate high-capacity lithium storage
We report use of black phosphorus (BP) as the active anode for high-rate, high-capacity Li storage. The formation of covalent bonds with graphitic carbon restrains edge reconstruction in layered BP particles to ensure open edges for fast Li+ entry; the coating of the covalently bonded BP-graphite particles with electrolyte-swollen polyaniline yields a stable solid–electrolyte interphase and inhibits the continuous growth of poorly conducting Li fluorides and carbonates to ensure efficient Li+ transport. The resultant composite anode demonstrates an excellent combination of capacity, rate, and cycling endurance. (Source: ScienceNOW)
