RNA‐Guided Engineering of the Chloroplast Genome Enabled by Plastid‐Expressed Guide RNAs
ABSTRACT Our goal is to develop RNA‐guided engineering of the chloroplast genome using the CRISPR/Cas9 system. We designed chloroplast minigenes to obtain properly sized single guide RNAs (sgRNAs) in tobacco chloroplasts. The sgRNA 5′ end is defined by transcription from an rRNA operon promoter, and its 3′ end by processing a downstream tRNA (trnG) or ...

Aim Major depressive disorder (MDD) is a leading cause of disability and carries a high risk of suicide. MicroRNAs (miRNAs) are epigenetic regulators implicated in MDD and can be regulated by DNA methylation, potentially reshaping downstream gene networks.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Abstract Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age‐related diseases and might contribute to the development of both sarcopenia and frailty. In this

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

This study develops a dynamic surface‐enhanced Raman scattering (D‐SERS) platform integrating multiscale nanoparticle geometry, quantum dot coupling, surface‐energy programming, and a multilayer perceptron model for AI‐assisted classification. It enables ultrahigh sensitivity, noninvasive detection, and specific Helicobacter pylori identification.

ABSTRACT Resistance to chemotherapy, which is demonstrated in almost every patient with advanced‐stage lung cancer (ALC), underscores an urgent need to unravel the underlying molecular mechanisms and identify novel strategies to overcome drug resistance. In the present study, an attempt was made to identify epigenetic targets and modulators that can be

Minimally processed, human‐grade diet alters canine epigenetic ageing: Results from a pilot study
Abstract Background Diet plays a critical role in promoting wellness and longevity in both humans and canines. Epigenetic ageing clocks have emerged as accurate tools for assessing biological ageing and evaluating dietary and lifestyle interventions in humans and mice.

ABSTRACT Rationale The varied properties of metabolomics components dictate the tools used in mass spectrometry (MS) characterization including the selection of the ionization source. However, the ionization of select compounds limits characterization efficiency.
