Twelve-week high-intensity interval training (HIIT), moderate-to-vigorousintensity continuous training (MICT), and Nordic walking (NW) have been shown to improve functional capacity, quality of life (QoL), and depression symptoms in patients with coronary artery disease. However, their prolonged effects or whether the improvements can be sustained remains unknown. In this study we compared the effects of 12… Continue reading Sustained Effects of Different Exercise Modalities on Physical and Mental Health in Patients With Coronary Artery Disease: A Randomized Clinical Trial
Microtubule assembly by tau impairs endocytosis and neurotransmission via dynamin sequestration in Alzheimer’s disease synapse model
Elevation of soluble wild-type (WT) tau occurs in synaptic compartments in Alzheimer’s disease. We addressed whether tau elevation affects synaptic transmission at the calyx of Held in slices from mice brainstem. Whole-cell loading of WT human tau (h-tau) in presynaptic terminals at 10–20 µM caused microtubule (MT) assembly and activity-dependent rundown of excitatory neurotransmission. Capacitance… Continue reading Microtubule assembly by tau impairs endocytosis and neurotransmission via dynamin sequestration in Alzheimer’s disease synapse model
Molecular signatures of long-term hepatocellular carcinoma risk in nonalcoholic fatty liver disease
Predicting liver cancer riskNonalcoholic fatty liver disease (NAFLD) raises the risk of developing hepatocellular carcinoma (HCC), but this risk can be difficult to quantify and disease onset can still be difficult to catch early. Fujiwara et al. developed hepatic transcriptome and serum secretome–derived signatures to predict NAFLD-related HCC in patients over 15 years of observation.… Continue reading Molecular signatures of long-term hepatocellular carcinoma risk in nonalcoholic fatty liver disease
Vitamin D and brain health: an observational and Mendelian randomization study
BackgroundHigher vitamin D status has been suggested to have beneficial effects on the brain. ObjectivesTo investigate the association between 25-hydroxyvitamin D [25(OH)D], neuroimaging features, and the risk of dementia and stroke. MethodsWe used prospective data from the UK Biobank (37–73 y at baseline) to examine the association between 25(OH)D concentrations with neuroimaging outcomes (N =… Continue reading Vitamin D and brain health: an observational and Mendelian randomization study
Carbon dioxide rises beyond acceptable safety levels in children under nose and mouth covering: Results of an experimental measurement study in healthy children
AbstractNose and mouth covering (NMC) has been made compulsory for children in many countries during the Covid-19 pandemic. We wanted to determine the average CO2 levels in inhaled air with NMC in children between age 6 and 17. We used short term measurements under surgical masks and FFP2 masks according to European norm EN 149,… Continue reading Carbon dioxide rises beyond acceptable safety levels in children under nose and mouth covering: Results of an experimental measurement study in healthy children
Interleukin-27 signaling serves as an immunological checkpoint for innate cytotoxic cells to promote hepatocellular carcinoma
AbstractWhile inflammatory mechanisms driving hepatocellular carcinoma (HCC) had been proposed, the regulators of anti-cancer immunity in HCC remain poorly understood. We found that IL-27 receptor (IL-27R) signaling promotes HCC development in vivo. High IL-27EBI3 cytokine or IL-27RA expression correlated with poor prognosis for patients with HCC. Loss of IL-27R suppressed HCC in vivo in two… Continue reading Interleukin-27 signaling serves as an immunological checkpoint for innate cytotoxic cells to promote hepatocellular carcinoma
Sex differences in sequelae from COVID-19 infection and in long COVID syndrome: a review
AbstractObjectiveWe conducted literature reviews to uncover differential effects of sex on sequelae from coronavirus disease 2019 (COVID-19) and on long COVID syndrome. MethodsTwo authors independently searched OvidSP in Embase, Medline, Biosis, and Derwent Drug File. Publications reporting original, sex-disaggregated data for sequelae of COVID-19 (published before August 2020) and long COVID syndrome (published before June… Continue reading Sex differences in sequelae from COVID-19 infection and in long COVID syndrome: a review
A predictive model using the mesoscopic architecture of the living brain to detect Alzheimer’s disease
BackgroundAlzheimer’s disease, the most common cause of dementia, causes a progressive and irreversible deterioration of cognition that can sometimes be difficult to diagnose, leading to suboptimal patient care. MethodsWe developed a predictive model that computes multi-regional statistical morpho-functional mesoscopic traits from T1-weighted MRI scans, with or without cognitive scores. For each patient, a biomarker called… Continue reading A predictive model using the mesoscopic architecture of the living brain to detect Alzheimer’s disease
Robust variation in infant gut microbiome assembly across a spectrum of lifestyles
Establishing early diversityHumans living an urbanized lifestyle in industrialized countries tend to have less diverse microbiota than people living more rural existences. Using fecal 16S ribosomal RNA sequencing, Olm et al. found that after the first 6 months of life, the microbiome of infants living in contrasting environments diverged from Bifidobacteria-dominated assemblages. Deep metagenomic sequencing… Continue reading Robust variation in infant gut microbiome assembly across a spectrum of lifestyles
