A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

First synthetic circuit consists of entirely fast, reversible protein-protein interactions

Synthetic biology offers a way to engineer cells to perform novel functions, such as glowing with fluorescent light when they detect a certain chemical. Usually, this is done by altering cells so they express genes that can be triggered by a certain input.

Long-term exposure to air pollutants increases the risk of dysmenorrhea in women

Dysmenorrhea, that is, frequent severe and painful cramps during menstruation from abnormal contractions of the uterus, is the most common of all gynecological disorders. It affects between 16-91% of girls and women of reproductive age, of whom 2%-29% have symptoms severe enough to restrict their daily activity.

Brain cells snap DNA strands in numerous locations to make memories

The urgency to remember a dangerous experience requires the brain to make a series of potentially dangerous moves: Neurons and other brain cells snap open their DNA in numerous locations--more than previously realized, according to a new study--to provide quick access to genetic instructions for the mechanisms of memory storage.

Serum testosterone status recovery an accurate predictor of survival in male COVID-19 patients

In a study available on the medRxiv* the preprint server, researchers from Spain showed that testosterone trajectories are very accurate individual predictors of survival in male patients with COVID-19. To better understand the relationship between testosterone levels and disease severity, they studied a group of male and female COVID-19 patients assessing their serum and blood biomarkers in association with outcome of disease.

Castration of male sheep slows DNA aging

Most of us are familiar with the fact that women live longer than men. But fellas, if we told you there was one thing that could be done to increase your lifespan, would you do it?

Exposure to air pollutants during pregnancy may affect thyroxine levels in newborns

Maternal exposure to air pollution during pregnancy has often been linked to adverse effects on the health of the newborn. However, there are very few studies on the subject.

Maternal and paternal behaviors in voles promoted by the exact same neural pathways

Like female voles, connections between oxytocin neurons in the hypothalamus and dopamine neurons in reward areas drive parental behaviors in male voles, according to new research published in JNeurosci.

World-first study uses artificial intelligence to map the risks of ovarian cancer in women

The University of South Australia will lead a world-first study, using artificial intelligence, to map the risks of the most fatal reproductive cancer in women worldwide so it can be detected and treated earlier.

Loss of PTHrP hormone can prevent metastases, improve survival in mice with pancreatic cancer

Lowering levels of a hormone called PTHrP can prevent metastases and improve survival in mice with pancreatic cancer and could lead to a new way to treat patients, according to a study from cancer researchers at Columbia University Vagelos College of Physicians and Surgeons and Herbert Irving Comprehensive Cancer Center and with collaborators at the University of Pennsylvania.

Multimodality therapy critical for treating more aggressive prostate cancers

Men with high-risk prostate cancer with at least one additional aggressive feature have the best outcomes when treated with multiple healthcare disciplines, known as multimodality care, according to a UCLA study led by Dr. Amar Kishan, assistant professor of radiation oncology at the David Geffen School of Medicine at UCLA and a researcher at the UCLA Jonsson Comprehensive Cancer Center.

Researchers discover genetic markers that drive the timing of first sex and birth

An Oxford-led team, working with Cambridge and international scholars, has discovered hundreds of genetic markers driving two of life's most momentous milestones - the age at which people first have sex and become parents.

Can age, sex, BMI or blood group influence the immunogenicity of the Pfizer/BioNTech COVID-19 vaccine?

A group of Belgium researchers recently discuss their findings in the journal Microorganisms, which describe the influence of several factors on vaccine-induced immunogenicity.

New microchip can measure stress hormones in real time from a drop of blood

A Rutgers-led team of researchers has developed a microchip that can measure stress hormones in real time from a drop of blood.

Communicating with female friends decreases stress hormone levels for women across the lifespan

Directing a meeting, dialing up an old acquaintance, dictating the perfect tuna salad sandwich across a drive-through window. For business and for pleasure, human beings are in constant communication.

Researchers identify specific biomarkers for coronary microvascular disease

Although cardiovascular disease is the main cause of illness among women in the U.S., certain conditions such as coronary microvascular disease (CMD) cannot be easily diagnosed. In a new study, researchers at the University of Illinois Urbana-Champaign have identified specific biomarkers for CMD, which might reduce future hospitalizations.

Study finds higher risk of pre-eclampsia, hypertension in pregnancies derived from frozen embryos

A large cohort study drawn from the national IVF registry of France, which included almost 70,000 pregnancies delivered after 22 weeks gestation between 2013 and 2018, has found a higher risk of pre-eclampsia and hypertension in pregnancies derived from frozen-thawed embryos.

Higher risk of preeclampsia and pregnancy-induced hypertension as a result of embryo freezing for IVF

Researchers have established a strong association between the risk of developing hypertension and the artificial cycle for frozen-thawed embryo transfer.

Songbird plumage and testosterone levels are altered by wildfire

Fire can put a tropical songbird's sex life on ice. Following habitat-destroying wildfires in Australia, researchers found that many male red-backed fairywrens failed to molt into their red-and-black ornamental plumage, making them less attractive to potential mates. They also had lowered circulating testosterone, which has been associated with their showy feathers.

Study finds minimal SARS-CoV-2 viral load in vaginal secretions

The virus has also been observed to be present in blood, urine, feces, and tears, though not in semen. Vaginal secretions have not been consistently shown to be positive for the virus in most studies. The authors of a new study in the Journal of Clinical Medicine affirm that the presence of the virus in the vagina is rare, irrespective of pregnancy.

Differences in human and mouse brain cells have implications for research into neurological disorders

A UCLA-led study comparing brain cells known as astrocytes in humans and mice found that mouse astrocytes are more resilient to oxidative stress, a damaging imbalance that is a mechanism behind many neurological disorders.
