Oxytocin‐ und Vasopressin‐Photosonden zur Entschlüsselung der Neuropeptid‐Signalgebung mit hoher räumlicher und zeitlicher Präzision

Angewandte Chemie, EarlyView.
Neue biokompatible Oxytocin‐ und Vasopressin‐Photosonden mit modernsten Photocages. Diese Photosonden sind inaktiv und können mit spezifischen Lichtwellen entschützt werden, was eine Rezeptoraktivierung mit hoher zeitlicher und räumlicher Kontrolle ermöglicht. Abbildung erstellt mit https://BioRender.com ZUSAMMENFASSUNG Das Oxytocin/Vasopressin (OT/VP)

Lymphocyte Micronucleus Formation Is Driven by Inflammation‐Induced Oxidative DNA Damage in Oesophageal Cancer Development

International Journal of Cancer, EarlyView.
Chromosomal instability is a hallmark of cancer, but minimally invasive ways to detect systemic DNA damage and cancer risk remain limited. Here, using patient blood samples, the authors investigated lymphocyte micronuclei (MN) frequency as a potential marker of DNA damage across the progression from gastroesophageal reflux disease to Barrett's ...

Analysis of induced genetic variability for morphological and floral characters with male sterility in sesame (Sesamum indicum L.)

Electronic Journal of Plant Breeding, 2018
Male sterility can be useful to obtain high yielding sesame hybrids with reduced cost and labour. It can be induced artificially into the released cultivars by using chemical mutagens.

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

Safety Evaluation of an Aqueous Root and Leaf Extract of Ashwagandha (Withania somnifera)

Phytotherapy Research, EarlyView.
Sensoril, an aqueous root and leaf extract of ashwagandha showed no evidence of mutagenicity in the in vitro Ames assay, was negative in the in vitro micronucleus, in vivo mammalian bone marrow chromosome aberration assays, and was well tolerated in the rat at up to 4000 mg/kg BW/day when administered orally for a period of 90 days. The data from these

Enhancement of immune checkpoint inhibitor efficacy by DHX58+ SELL+ T cells in advanced gastric cancer

VIEW, EarlyView.
We created a coculture system using patient‐derived organoids (PDOs) and tumor‐infiltrating lymphocytes (TILs) that mimics important interactions between PDOs and TILs in the presence of various ICIs. Our findings reveal that CD62L+ T cells, activated by CD44+ cancer stem cells (CSCs), facilitate tumor regression in samples sensitive to ICIs, which is ...
