Discovery of a novel pseudo β-hairpin structure of N-truncated amyloid-β for use as a vaccine against Alzheimer’s disease

One of the hallmarks of Alzheimer’s disease (AD) are deposits of amyloid-beta (Aβ) protein in amyloid plaques in the brain. The Aβ peptide exists in several forms, including full-length Aβ1-42 and Aβ1-40 – and the N-truncated species, pyroglutamate Aβ3-42 and Aβ4-42, which appear to play a major role in neurodegeneration. We previously identified a murine… Continue reading Discovery of a novel pseudo β-hairpin structure of N-truncated amyloid-β for use as a vaccine against Alzheimer’s disease

The Self in the Mind’s Eye: Revealing How We Truly See Ourselves Through Reverse Correlation

Is there a way to visually depict the image people “see” of themselves in their minds’ eyes? And if so, what can these mental images tell us about ourselves? We used a computational reverse-correlation technique to explore individuals’ mental “self-portraits” of their faces and body shapes in an unbiased, data-driven way (total N = 116… Continue reading The Self in the Mind’s Eye: Revealing How We Truly See Ourselves Through Reverse Correlation

Transmission of SARS-CoV-2 Delta Variant Among Vaccinated Healthcare Workers, Vietnam

Background: Data on breakthrough SARS-CoV-2 Delta variant infections are limited. Methods: We studied breakthrough infections among healthcare workers of a major infectious diseases hospital in Vietnam. We collected demographics, vaccination history and results of PCR diagnosis alongside clinical data. We measured SARS-CoV-2 (neutralizing) antibodies at diagnosis, and at week 1, 2 and 3 after diagnosis.… Continue reading Transmission of SARS-CoV-2 Delta Variant Among Vaccinated Healthcare Workers, Vietnam

Secondary Antibiotic Prophylaxis for Latent Rheumatic Heart Disease

Rheumatic heart disease affects more than 40.5 million people worldwide and results in 306,000 deaths annually. Echocardiographic screening detects rheumatic heart disease at an early, latent stage. Whether secondary antibiotic prophylaxis is effective in preventing progression of latent rheumatic heart disease is unknown. METHODSWe conducted a randomized, controlled trial of secondary antibiotic prophylaxis in Ugandan… Continue reading Secondary Antibiotic Prophylaxis for Latent Rheumatic Heart Disease

Transparency of COVID-19 vaccine trials: decisions without data

Summary boxData transparency has become a well-established norm in biomedical research, and is especially important for broadly used public health interventions like COVID-19 vaccines. Tax payers helped fund COVID-19 vaccine trials and should have the right to access the results. There is inadequate availability of COVID-19 vaccine trial documents and data; individual participant data will… Continue reading Transparency of COVID-19 vaccine trials: decisions without data

Serum Nonesterified #Fatty Acids and Incident #Stroke: The CHS

Significant associations between total nonesterified fatty acid (NEFA) concentrations and incident stroke have been reported in some prospective cohort studies. We evaluated the associations between incident stroke and serum concentrations of nonesterified saturated, monounsaturated, polyunsaturated, and trans fatty acids. Methods and ResultsCHS (Cardiovascular Health Study) participants (N=2028) who were free of stroke at baseline (1996–1997)… Continue reading Serum Nonesterified #Fatty Acids and Incident #Stroke: The CHS

Downregulation of Erythrocyte miR-210 Induces #Endothelial Dysfunction in Type 2 #Diabetes

Red blood cells (RBCs) act as mediators of vascular injury in type 2 diabetes mellitus (T2DM). miR-210 plays a protective role in cardiovascular homeostasis and is decreased in whole blood of T2DM mice. We hypothesized that downregulation of RBC miR-210 induces endothelial dysfunction in T2DM. RBCs were co-incubated with arteries and endothelial cells ex vivo… Continue reading Downregulation of Erythrocyte miR-210 Induces #Endothelial Dysfunction in Type 2 #Diabetes

Experiences of Work-Family Conflict and #Mental Health Symptoms by Gender Among Physician Parents During the #COVID-19 Pandemic

The COVID-19 pandemic has placed increased strain on health care workers and disrupted childcare and schooling arrangements in unprecedented ways. As substantial gender inequalities existed in medicine before the pandemic, physician mothers may be at particular risk for adverse professional and psychological consequences. Objective To assess gender differences in work-family factors and mental health among… Continue reading Experiences of Work-Family Conflict and #Mental Health Symptoms by Gender Among Physician Parents During the #COVID-19 Pandemic

Charting host-microbe co-metabolism in #skin #aging and application to metagenomics data

During aging of human skin, a number of intrinsic and extrinsic factors cause the alteration of the skin’s structure, function and cutaneous physiology. Many studies have investigated the influence of the skin microbiome on these alterations, but the molecular mechanisms that dictate the interplay between these factors and the skin microbiome are still not fully… Continue reading Charting host-microbe co-metabolism in #skin #aging and application to metagenomics data
