Genetic polymorphisms and phylogenetic characteristics of Tibeto-Burman-speaking Lahu population from southwest China based on 41 Y-STR loci

Annals of Human Biology, 2023
Background Male sex-linked Y-chromosome short tandem repeats (Y-STRs) have been widely used in forensic cases and population genetics research. At present, the forensic-related Y-STR data in the Chinese Lahu population are still poorly understood. Aim To

<i>Gigantochloa falcihumeris</i> (Poaceae, Bambusoideae), a New Paleotropical Woody Bamboo Species From Southwest Yunnan, China. [PDF]

Ecol Evol
We describe Gigantochloa falcihumeris, a new species of paleotropical woody bamboo discovered in Southwest Yunnan, China. It is distinguished by its culm leaf sheath shoulders that prominently rise into a distinctive ca. 1 cm long falcate point.

Programming Nanostructure Formation Through Furin-Triggered Isopeptide Conversion and Peptide Self-Assembly. [PDF]

Macromol Biosci
A kinked isopeptide with a furin recognition sequence (RVRR) is designed to respond to the protease furin by transforming into a linear peptide that self‐assembles into elongated nanofibers. This study shows how enzyme‐triggered transformation of a synthetic kinked isopeptide enables precise and controlled nanostructure formation, offering new ...

Co-Assemblies Regulate the Catalytic Activity of Peptide Fibrils. [PDF]

Angew Chem Int Ed Engl
Catalytic self‐assembling peptides (cSAPs) form fibrils that catalyze the retro‐aldol reaction of Methodol. Co‐assembly with inactive peptides tunes catalytic efficiency by altering substrate accessibility and the distance to the nucleophilic lysine.

Light-Triggered Disassembly of Peptide Nanostructures. [PDF]

Chembiochem
Two amphiphilic peptides incorporating anthracene as a light‐responsive moiety that assemble into 2D‐sheets or ribbons are designed. These nanostructures are disassembled upon irradiation with 365 nm light by bimolecular [4 + 4] cycloaddition. The reaction kinetics are depended on peptide preorganization, linking structure to reactivity.

Photoswitchable Peptides as Molecular Tools to Encode Structural Order and Disorder in Intracellular Assemblies. [PDF]

Angew Chem Int Ed Engl
We present a photoswitchable peptide conjugate which exhibits isomerism‐dependent self‐assembly: the planar trans‐isomer assembles into well‐ordered nanofibers while the non‐planar cis‐isomer yields disordered aggregates. Our study offers a direct visualization on the effects of structure formation inside living cells.

Genetic mixed diversity landscape in the paternal lineages of 11 populations inhabiting Southwest China according to the analysis of 25 Y-STRs [PDF]

BMC Ecology and Evolution
Y-STR genotyping can be used to predict the genetic mixed landscape of different populations effectively. In this study, 25 Y-STR loci were detected in 745 unrelated healthy males from the Bai, Bouyei, Dong, Gelao, Hui, Maonan, Mulao, Shui, Tujia, Yi and
