DALLAS, July 1, 2020 -- Lifetime discrimination is a chronic stressor that may increase the risk for hypertension also known as high blood pressure, in African Americans, according to new research published today in Hypertension, an American Heart Association journal.
COLUMBUS, Ohio -- Kids who miss a lot of school from kindergarten to eighth grade may suffer unexpected costs as young adults, a new study finds.
Researchers found that those who were more regularly absent in these early years of school were less likely to vote, reported having greater economic difficulties and had poorer educational outcomes when they were 22 to 23 years old.
The results suggest early school absenteeism should be taken more seriously, said Arya Ansari, lead author of the study and assistant professor of human sciences at The Ohio State University.
Tsukuba, Japan - Researchers commonly culture bacteria for many purposes, such as to screen pharmaceuticals and manufacture vaccines. In these cases, shake flasks have been commonly and generally used for over 90 years to cultivate microbes.
It's not just health, social and economic consequences from COVID-19 that have impacted the world. Travel behavior also has been significantly affected. Using statewide traffic data from the Florida Department of Transportation (FDOT), a study demonstrates the drastic changes in human behavior during the onset of the pandemic. With more than 20 million residents, Florida was selected because of its enormous diversity and unique demographic and commercial characteristics.
Rural hospitals are more likely than urban facilities to have access to telehealth, a once-underused service that now is playing a key role in treating coronavirus patients, according to research by two health administration professors in Florida Atlantic University's College of Business.
People can engage in cooperative behavior even among strangers with no direct expectation of personal benefit. For such cooperative behavior to be sustained, a mechanism needs to be in place to ensure that benefits are returned to the individuals who cooperate. As the proverb goes, "One good turn deserves another." This mechanism is generally referred to as indirect reciprocity.
A compound produced in the gut when we eat red meat damages our arteries and may play a key role in boosting risk of heart disease as we get older, according to new University of Colorado Boulder research.
The study, published this month in the American Heart Association journal Hypertension, also suggests that people may be able to prevent or even reverse such age-related decline via dietary changes and targeted therapies, like novel nutritional supplements.
Myelodysplastic/myeloproliferative neoplasms (MDS/MPN) is a group of rare malignancies with overlapping features from myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN), that include a variety of diseases depending on their phenotype (hematological and morphological characteristics). Adult MSD/MPN include Chronic Myelomonocytic Leukaemia (CMML), atypical chronic myeloid leukemia (aCML), MDS/MPN with ring sideroblasts and thrombocytosis (MDS/MPN-RS-T) and MDS/MPN unclassifiable (MDS/MPN-U).
The synaptonemal complex is a ladder-like cell structure that plays a major role in the development of egg and sperm cells in humans and other mammals. "The structure of this complex has hardly been changed in evolution, but its protein components vary greatly from organism to organism," says Professor Ricardo Benavente, cell and developmental biologist at the Biocenter of Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany.
This work has been published in The Plant Genome very recently. This study has analyzed one environment-sensitive genic male sterile (EGMS) line that exhibited fertility transition under specified environmental conditions. Fertility transition here refers to the reversion of male sterile condition producing viable pollen to become male fertile plant and vice-versa. An EGMS line, if understood better, could be used together with any elite line for hybrid seed production.
Whenever a germ gets into the human body, the immune system usually responds immediately to fight off the enemy attacker. One of our defense system's most important strategies involves B lymphocytes, also known as B cells, which produce antibodies that target and neutralize pathogens. B cells play a central role in adaptive immunity and, together with T cells and components of the innate system, they protect the body against foreign pathogens, allergens and toxins.

Why do we age? What exactly is happening in our bodies? And can we do anything about it? Mankind has sought answers to these questions since time immemorial. While the pharmaceutical scientists Alexandra K. Kiemer and Jessica Hoppstädter from Saarland University are not claiming to have solved this ancient problem, they have uncovered processes within our immune system that contribute to ageing. Kiemer and Hoppstädter have shown that low levels of the hormone cortisol and the protein known as GILZ can trigger chronic inflammatory responses in the body.
Learning, memory and behavioral disorders can arise when the connections between neuron, called synapses, do not change properly in response to experience. Scientists have studied this "synaptic plasticity" for decades, but a new study by researchers at MIT's Picower Institute for Learning and Memory highlights several surprises about some of the basic mechanisms by which it happens. Getting to the bottom of what underlies some of those surprises, the research further suggests, could yield new treatments for a disorder called Fragile X that causes autism.
Australian researchers have shown for the first time that a new drug used to treat breast cancer patients damages the store of immature eggs in the ovaries of mice.
The authors of the study, which is published today (Wednesday) in Human Reproduction [1], one of the world's leading reproductive medicine journals, say the drug olaparib is being used to treat young as well as older women with breast cancer that is driven by mutations in the BRCA1/2 genes, but without knowing its effect on fertility.

There are about 75 different types of cells in the human brain. What makes them all different? Researchers at Baylor College of Medicine have developed a new set of computational tools to help answer this question. Although different cell types from the same organism carry the same DNA, they look and function differently because a different set of genes is active or inactive in each. Cells switch genes on or off by using epigenetic mechanisms, such as DNA methylation, which involves tagging genes with methyl chemical groups.
