Regulatory mechanisms in the biosynthesis of isoleucine and valine I. Genetic derepression of enzyme formation

open access: yes, 1964
A total of 60 mutants of Escherichia coli K-12 resistant to 10−2M valine were isolated from the valine-sensitive F' strain AB1206. Conjugation experiments showed that in five of these mutants the valine-resistance locus is closely linked to the ...

Second‐trimester multimetabolite panel for early preeclampsia rule‐out

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective We aimed to establish a high‐sensitivity, multimetabolite rule‐out model for the development of preeclampsia (PE), prioritizing minimizing false negatives to exclude low‐risk individuals from intensive surveillance confidently. Methods In this prospective, nested case–control study, maternal serum samples were collected between 20+0 ...

Bioinorganic Site‐Specific Conjugation of Multi‐Arm Linkers to Create Pharmaceuticals With Targeting and Effector Functions

open access: yesJournal of the Chinese Chemical Society, EarlyView.
This Account showcases a modular, multi‐arm linker platform that decouples payload loading from antibody conjugation. By leveraging a computationally designed ACPGHA zinc‐binding motif, we demonstrate the construction of homogeneous antibody‐drug conjugates and theranostic antibody‐radionuclide conjugates with high payload loading. The multi‐arm linker

Alterations in brain metabolites in rats with experimental periodontitis: A metabolomic approach

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Periodontitis (PD) is a chronic inflammatory disease with systemic effects. Emerging evidence suggests a link between periodontal inflammation and neurological changes, but the biochemical mechanisms in key brain regions, such as the hippocampus and amygdala, remain unclear.

Macronutrient and micronutrient profiles of meat types: insights into human health and diet

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Despite considerable advances in global health and nutrition, emerging challenges such as population growth, climate change, and limited natural resources continue to threaten food security. Meat remains an essential component of the human diet, supplying high‐quality proteins, essential amino acids, lipids, vitamins, and minerals necessary ...
