Protozoa-enhanced conjugation frequency alters the dissemination of soil antibiotic resistance.

Protozoa, as primary predators of soil bacteria, represent an overlooked natural driver in the dissemination of antibiotic resistance genes. However, the effects of protozoan predation on antibiotic resistance genes dissemination at the community level, along with the underlying mechanisms, remain unclear. Here we used fluorescence-activated cell sorting, qPCR, combined with metagenomics and reverse transcription quantitative PCR, to unveil how protozoa (Colpoda steinii and Acanthamoeba castellanii) influence the plasmid-mediated transfer of antibiotic resistance genes to soil microbial communities.

Multimodal assessment predicts cognitive impairment after aneurysmal subarachnoid hemorrhage: a prospective cohort study.

Background: Risk factors and mechanisms of cognitive impairment (CI) after aneurysmal subarachnoid hemorrhage (aSAH) are unclear. This study used a neuropsychological battery, MRI, ERP and CSF and plasma biomarkers to predict long-term cognitive impairment after aSAH.

Materials And Methods: 214 patients hospitalized with aSAH (n = 125) or unruptured intracranial aneurysms (UIA) (n = 89) were included in this prospective cohort study.

HER2 regulates autophagy and promotes migration in gastric cancer cells through the cGAS-STING pathway.

In gastric cancer, the relationship between human epidermal growth factor receptor 2 (HER2), the cyclic GMP-AMP synthase-stimulator of the interferon genes (cGAS-STING) pathway, and autophagy remains unclear. This study examines whether HER2 regulates autophagy in gastric cancer cells via the cGAS-STING signaling pathway, influencing key processes such as cell proliferation and migration. Understanding this relationship could uncover new molecular targets for diagnosis and treatment.

Association Between Diurnal Temperature Range and Risk of Cardiomyopathy-Induced Hospitalisation in Henan, China: A Time-Series Study.

Purpose: The effect of the diurnal temperature range (DTR) on human health in diverse geographic areas and the potential confounding factors are not fully understood. Additionally, while a robust association has been reported between temperature and cardiomyopathy (CM), evidence of the impact of DTR is relatively limited. Here, we determined whether an association exists between DTR and CM hospitalisations in vulnerable populations.
