Objective: To control the quality of the product, quantitative fingerprint was used to evaluate the composition of the amino acids in the Xingnao Tongluo injection.
Method: The method of the quantitative fingerprint to the amino acids composition was established through AccQ Tag precolumn derivatization. The quality was evaluated by the quantitative test of the amino acids and the similarity in ten batches.
Result: The Xingnao Tongluo injection contained 12 amino acids and the contents of these amino acids were stable. All the ten batches of the samples had similarity of more than 0.90.
Conclusion: The method was accurate, feasible and could be a simple and effective way to evaluate the quality of the traditional Chinese medicine.

L-valine holds wide-ranging applications in medicine, food, feed, and various industrial sectors. Escherichia coli, a pivotal strain in industrial L-valine production, features a concise fermentation period and a well-defined genetic background. This study focuses on mismatch repair genes (mutH, mutL, mutS, and recG) and genes associated with mutagenesis (dinB, rpoS, rpoD, and recA), employing a high-glucose adaptive culture in conjunction with metabolic modifications to systematically screen for superior phenotypes.

A new strategy has been developed to successfully produce the active component danshensu ex vivo. For this purpose, phenylalanine dehydrogenase from Bacillus sphaericus was combined with the novel hydroxyphenylpyruvate reductase from Mentha x piperita, thereby providing an in situ cofactor regeneration throughout the conversion process. The purified enzymes were co-immobilized and subsequently employed in batch biotransformation, resulting in 60% conversion of 10 mM L-dopa within 24 h, with a catalytic amount of NAD as cofactor.

The basal ganglia (BG) are an evolutionarily conserved and phylogenetically old set of sub-cortical nuclei that guide action selection, evaluation, and reinforcement. The entopeduncular nucleus (EP) is a major BG output nucleus that contains a population of GABA/glutamate cotransmitting neurons (EP) that specifically target the lateral habenula (LHb) and whose function in behavior remains mysterious. Here, we use a probabilistic switching task that requires an animal to maintain flexible relationships between action selection and evaluation to examine when and how GABA/glutamate cotransmitting neurons contribute to behavior.

Epidermal melanocytes form synaptic-like contacts with cutaneous nerve fibers, but the functional outcome of these connections remains elusive. In this pilot study we used our fully humanized re-innervated skin organ culture model to investigate melanocyte-nerve fiber interactions in UV-B-induced melanogenesis. UV-B-irradiation significantly enhanced melanin content and tyrosinase activity in re-innervated skin compared to non-innervated controls, indicating that neuronal presence is essential for exacerbating pigmentation upon UV-B irradiation in long-term culture.
