Hypoxia drives aging and promotes age-related cognition and hearing functional decline. Despite the role of erythrocytes in oxygen (O2) transport, their role in the onset of aging and age-related cognitive decline and hearing loss (HL) remains undetermined. Recent studies revealed that signaling through the erythrocyte adenosine A2B receptor (ADORA2B) promotes O2 release to counteract hypoxia… Continue reading #Erythrocyte adenosine A2B receptor prevents #cognitive and #auditory dysfunction by promoting hypoxic and metabolic reprogramming

Informed consent disclosure to vaccine trial subjects of risk of #COVID-19 vaccines worsening clinical disease
Aims of the study: Patient comprehension is a critical part of meeting medical ethics standards of informed consent in study designs. The aim of the study was to determine if sufficient literature exists to require clinicians to disclose the specific risk that COVID-19 vaccines could worsen disease upon exposure to challenge or circulating virus. Methods… Continue reading Informed consent disclosure to vaccine trial subjects of risk of #COVID-19 vaccines worsening clinical disease
#Renal hemodynamics across the adult lifespan: Relevance of #flow pulsatility to chronic kidney disease
Elevated renal flow pulsatility may contribute to the pathogenesis of chronic kidney disease (CKD). The purpose of this study was to investigate the associations among age, renal flow pulsatility, and CKD biomarkers in non-CKD adults and CKD patients. MethodsNon-CKD adults (n = 415) and CKD patients (n = 136) aged between 22 and 83 years underwent the renal blood flow… Continue reading #Renal hemodynamics across the adult lifespan: Relevance of #flow pulsatility to chronic kidney disease
Adaptive circuit dynamics across human #cortex during evidence accumulation in changing #environments
Many decisions under uncertainty entail the temporal accumulation of evidence that informs about the state of the environment. When environments are subject to hidden changes in their state, maximizing accuracy and reward requires non-linear accumulation of evidence. How this adaptive, non-linear computation is realized in the brain is unknown. We analyzed human behavior and cortical… Continue reading Adaptive circuit dynamics across human #cortex during evidence accumulation in changing #environments
Artificial #Sweeteners Negatively Regulate Pathogenic Characteristics of Two Model #Gut Bacteria, E. coli and E. faecalis
Artificial sweeteners (AS) are synthetic sugar substitutes that are commonly consumed in the diet. Recent studies have indicated considerable health risks which links the consumption of AS with metabolic derangements and gut microbiota perturbations. Despite these studies, there is still limited data on how AS impacts the commensal microbiota to cause pathogenicity. The present study… Continue reading Artificial #Sweeteners Negatively Regulate Pathogenic Characteristics of Two Model #Gut Bacteria, E. coli and E. faecalis
Vaccine Breakthrough Infections with #SARS-CoV-2 Variants
Emerging variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are of clinical concern. In a cohort of 417 persons who had received the second dose of BNT162b2 (Pfizer–BioNTech) or mRNA-1273 (Moderna) vaccine at least 2 weeks previously, we identified 2 women with vaccine breakthrough infection. Despite evidence of vaccine efficacy in both women, symptoms… Continue reading Vaccine Breakthrough Infections with #SARS-CoV-2 Variants
Timing of #chocolate intake affects hunger, substrate oxidation, and #microbiota: A randomized controlled trial
Eating chocolate in the morning or in the evening/at night, may differentially affect energy balance and impact body weight due to changes in energy intake, substrate oxidation, microbiota (composition/function), and circadian-related variables. In a randomized controlled trial, postmenopausal females (n = 19) had 100 g of chocolate in the morning (MC), in the evening/at night… Continue reading Timing of #chocolate intake affects hunger, substrate oxidation, and #microbiota: A randomized controlled trial
#Ivermectin for Prevention and Treatment of #COVID-19 InfectionA Systematic Review, Meta-analysis, and Trial Sequential Analysis to Inform Clinical Guidelines
Repurposed medicines may have a role against the SARS-CoV-2 virus. The antiparasitic ivermectin, with antiviral and anti-inflammatory properties, has now been tested in numerous clinical trials. Areas of uncertainty:We assessed the efficacy of ivermectin treatment in reducing mortality, in secondary outcomes, and in chemoprophylaxis, among people with, or at high risk of, COVID-19 infection. Data… Continue reading #Ivermectin for Prevention and Treatment of #COVID-19 InfectionA Systematic Review, Meta-analysis, and Trial Sequential Analysis to Inform Clinical Guidelines
Dynamic innate immune response determines susceptibility to #SARS-CoV-2 infection and early replication kinetics
Initial replication of SARS-CoV-2 in the upper respiratory tract is required to establish infection, and the replication levelcorrelates with the likelihood of viral transmission. Here, we examined the role of host innate immune defenses in restrictingearly SARS-CoV-2 infection using transcriptomics and biomarker-based tracking in serial patient nasopharyngeal samples andexperiments with airway epithelial organoids. SARS-CoV-2 initially… Continue reading Dynamic innate immune response determines susceptibility to #SARS-CoV-2 infection and early replication kinetics
