Biochemical variables have been determined in 28 patients before and after resection of carcinoma of colon or rectum. A synthetic oral diet was given for four days before operation, (0.1 gN.kg/day and 165 kJ.kg/day) and four isocaloric intravenous regimens with different amounts and proportions of amino acids were given for six days after operation. During the preoperative diet the serum urea, glucose, urate, inorganic phosphate and cholesterol concentration decreased while those of triglyceride, iron and alanine amino-transferase increased. After operation the serum triglyceride, protein, albumin, iron, TIBC and urate concentrations decreased. The serum calcium fell in all groups receiving amino acids after operation while magnesium increased in all groups except the one receiving the highest amount of amino acids. The urea concentration decreased when no amino acids were given but increased when amino acids were administered whereas the reverse situation occurred with cholesterol. The highest increase in glucose level was observed when the highest amount of amino acids were given.

Backgrounds: Memory and emotion are especially vulnerable to psychiatric disorders such as post-traumatic stress disorder (PTSD), which is linked to disruptions in serotonin (5-HT) metabolism. Over 90% of the 5-HT precursor tryptophan (Trp) is metabolized via the Trp-kynurenine (KYN) metabolic pathway, which generates a variety of bioactive molecules. Dysregulation of KYN metabolism, particularly low levels of kynurenic acid (KYNA), appears to be linked to neuropsychiatric disorders.

Powdered germinated Thai rice () is widely utilised as a dietary supplement to support health and prevent diseases. This study investigated the bioactive compound profile of water extracts from beverage powder made from Thai germinated brown rice (GBRE) and assessed its anticancer effects on cholangiocarcinoma, lung cancer, and liver cancer cell lines. Proton nuclear magnetic resonance (1H-NMR) revealed 23 metabolites, including amino acids, sugar, phenolic compounds and nitrogenous compounds.

Porcine reproductive and respiratory syndrome virus (PRRSV), an important pathogen affecting the pig industry, is an RNA virus with high genetic diversity. In this study, 12,299 clinical samples were collected from northern China during 2021-2023 to investigate the molecular epidemiological characteristics and genetic evolution of PRRSV. All samples were screened using qRT-PCR and further analyzed through gene and whole-genome sequencing.
