[Applying Team Resource Management to Reduce the Urinary Catheter Usage Rate in Our Intensive Care Unit].

Background & Problems: According to the literature, 74%-84% of patients in adult critical care units have an indwelling catheter. The majority of medical and healthcare infections are urinary tract infections, which are related to urinary catheter usage. Furthermore, critical infections may cause bacteremia, which increases the risk of mortality.

Evolutionary gain of highly divergent tRNA specificities by two isoforms of human histidyl-tRNA synthetase.

The discriminator base N73 is a key identity element of tRNA. In eukaryotes, N73 is an "A" in cytoplasmic tRNA and a "C" in mitochondrial tRNA. We present evidence herein that yeast histidyl-tRNA synthetase (HisRS) recognizes both A73 and C73, but somewhat prefers A73 even within the context of mitochondrial tRNA.

The variation in the major constituents of the dried rhizome of Ligusticum chuanxiong (Chuanxiong) after herbal processing.

Background: Rhizoma Chuanxiong (RC; Chuanxiong), which is the dried rhizome of Ligusticum chuanxiong (Umbelliferae), is commonly used in Chinese medicine (CM) for improving blood circulation and dispersing blood stasis. RC is usually processed before use in clinical practice to enhance its therapeutic efficacy. This study aimed to investigate the temporal variations of the major constituents of RC by HPLC-DAD-MS during herbal processing to investigate the effects of an adjuvant (e.
