- ... Degradation of amoxicillin (AMXL) in aqueous solution induced by contact glow discharge electrolysis (CGDE) was investigated in this paper. Experimental results demonstrated that the higher initial concentration resulted in the lower degradation rate, but the higher amount of AMXL was removed. The addition of Fe²⁺ or Fe³⁺ efficiently accelerated the degradation of AMXL. Similarly, stainless steel ...

- ... Insulin-like growth factors (IGFs) stimulate myoblast proliferation and differentiation. It remains elusive how these mutually exclusive cellular responses are elicited by the same growth factor. Here we report that whereas IGF promotes myoblast differentiation under normoxia, it stimulates proliferation under hypoxia. Hypoxia activates the HIF-1 transcriptional program and knockdown of HIF-1α cha ...

- ... Hypothalamic neurons expressing Agouti-related peptide (AgRP) are critical for initiating food intake, but druggable biochemical pathways that control this response remain elusive. Thus, genetic ablation of insulin or leptin signaling in AgRP neurons is predicted to reduce satiety but fails to do so. FoxO1 is a shared mediator of both pathways, and its inhibition is required to induce satiety. Acc ...
