应用


  • 在静脉注射磷酸氢二钠发生全国短缺期间，评估新型肠内磷疗法与肠内营养。：单磷酸钠作为一种肠内磷补充剂接受了评估，为静脉注射磷酸盐短缺期间提供了一种可行的替代品，并改善了临床营养学中的患者护理（Harris et al., 2024）。

  • 两种测定阿糖胞苷和地塞米松（两种治疗白血病的联合用药）的色谱法：绿色分析视角。：单碱式磷酸钠被用作色谱法中的缓冲剂，提高了白血病药物的绿色分析测定，有助于可持续的分析实践（Magdy et al., 2024）。

The mating decisions of Drosophila melanogaster females are primarily revealed through either of two discrete actions: opening of the vaginal plates to allow copulation, or extrusion of the ovipositor to reject the male. Both actions are triggered by the male

Chemical and electrical synapses are the two major communication systems that permit cell-to-cell communication within the nervous system. Although most studies are focused on chemical synapses (glutamate, γ-aminobutyric acid, and other neurotransmitters), clearly both types of synapses interact and cooperate

Understanding drug glucuronidation in the dog, a preclinical animal, is important but currently poorly characterized at the level of individual enzymes. We have constructed cDNAs for the 10 dog UDP-glucuronosyltransferases of subfamily 1A (dUGT1As), expressed them in insect cells, and

The aim of this study was the development of poly(D,L-lactide-co-glycolide) (PLGA) microspheres with controlled porosity, to obtain microspheres that afford continuous release of a macromolecular model compound (blue dextran). PLGA microspheres with a size of around 40 μm and narrow size
