Clinical Manifestations.

Background: Disruption of sleep and circadian rhythms are associated with cognitive decline, preclinical Alzheimer's Disease (AD) pathology, and increased risk of dementia. Alleviating circadian rhythm and sleep disruption may improve cognition and reduce the progression of AD and related dementias (ADRD). Time-restricted eating (TRE), a circadian behavioral intervention that corrects disrupted eating rhythms by aligning food intake to the daytime, has demonstrated improvements in metabolic dysfunction and sleep quality.

Autoantibodies in hospitalised patients with COVID-19.

Objectives: CD209L and its homologous protein CD209 act as alternative entry receptors for the SARS-CoV-2 virus and are highly expressed in the virally targeted tissues. We tested for the presence and clinical features of autoantibodies targeting these receptors and compared these with autoantibodies known to be associated with COVID-19.

Methods: Using banked samples ( = 118) from Johns Hopkins patients hospitalised with COVID-19, we defined autoantibodies against CD209 and CD209L by enzyme-linked immunosorbent assay (ELISA).

Evaluating the Use of Environmental and Polygenic Risk Scores to Inform Colorectal Cancer Risk-Based Surveillance Intervals.

Introduction: United States Multi-Society Task Force colonoscopy surveillance intervals are based solely on adenoma characteristics, without accounting for other risk factors. We investigated whether a risk model including demographic, environmental, and genetic risk factors could individualize surveillance intervals under an "equal management of equal risks" framework.

Methods: Using 14,069 individuals from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial who had a diagnostic colonoscopy following an abnormal flexible sigmoidoscopy, we modeled the risk of colorectal cancer, considering the diagnostic colonoscopy finding, baseline risk factors (e.

Gene expression modulation in human aortic smooth muscle cells under induced physiological mechanical stretch.

In this study, we investigated gene expression in vitro of human primary Aortic smooth muscle cells (AoSMCs) in response to 9% physiological dynamic stretch over a 4 to 72-h timeframe using RT-qPCR. AoSMC were derived from primary culture and were exposed to continuous cycles of stretch and relaxation at 1 Hz by a computer-controlled Flex Jr.™ Tension System.
