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.

Smoking cannabis may increase sperm count

A new study has found that men who have smoked cannabis at some point in their lives have higher sperm counts than men who have never smoked the drug.

MUSC researchers examine the way estrogen affects drug addiction

Male rats have held steady as the focus of most addiction studies in the past. But as the field begins to take female rats into account, scientists see that drugs like methamphetamine affect the sexes differently, suggesting the basis for a change in addiction treatment.

New acute porphyria treatment shows promising results in clinical study

Acute porphyria is a group of uncommon diseases that can cause severe, potentially life-threatening attacks of abdominal pain, nausea, vomiting and paralysis. Liver transplantation is currently the only effective treatment available for the most seriously afflicted patients.

New study points to potential cure for addiction

The Akay Lab biomedical research team at the University of Houston is reporting in the journal Nature Scientific Reports that a possible cure for addiction may be found by following the pathways of significantly altered dopamine neurons in newborns who were chronically exposed to nicotine in utero.

Chloroplast retrograde signaling attenuates elongation response to shade in plants

Plants need sunlight to feed and grow. Without light, the photosynthesis, the reaction by which the plant chloroplasts convert atmospheric CO2 and water into sugars and oxygen, cannot take place.

Study: Maternal age, body mass index, race affect hormone concentrations in pregnancy

Hormone concentrations during early fetal development -- that may affect the child's development and increase the mother's risk for breast and ovarian cancer years later -- are significantly affected by maternal age, body mass index and race rather than lifestyle, according to a Rutgers study.

Women's brains age slower than men's

A new study has revealed that women have a more youthful brain compared to similar aged male counterparts when it comes to metabolism. The researchers found that with age the rates of metabolism of nutrients slow down in both men and women.

Early use of norepinephrine could benefit patients with sepsis and low blood pressure

Patients with septic shock who were treated with norepinephrine earlier than patients receiving standard care were more likely to have their blood pressure and shock stabilized within six hours of diagnosis, according to a randomized, double-blind, controlled trial published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.

Research opens up new therapeutic area to better manage chronic inflammatory diseases

Atherosclerosis is a disease defined by the accumulation of fatty deposits called plaques inside the arteries. It is a leading cause of heart attacks and strokes.

Researchers unravel path of metallodrug in a breast cancer cell

Some types of cancer cannot be treated with classical chemotherapy. Scientists from Inserm, CNRS, Sorbonne University, PSL university, University Grenoble Alpes and ESRF, the European Synchrotron, are working on a metallorganic molecule as an antitumor drug.

Warmer water and chemical exposure influence gene expression in North American fish

Warmer water temperatures, combined with low-level exposure to chemicals already known to be harmful to aquatic life, influence the expression of genes in the offspring of an abundant North American fish species - and threaten organisms whose sex determination is sensitive to water temperature.

Deciding post-exercise snack in advance may increase odds of eating healthy

You've just exercised for an hour, tracking the burned calories with a sense of satisfaction. Then comes a choice: munch on an apple or indulge in the chocolatey goodness of a brownie?

Researchers identify regulatory mechanism underlying obesity

Obesity − as research in the past decade has shown − is first and foremost a brain disease. Researchers at Helmholtz Zentrum München, partners in the German Center for Diabetes Research, have now discovered a molecular switch that controls the function of satiety neurons and therefore body weight. The findings were published in the journal 'Nature Metabolism'.

African-Americans have very high blood pressure 5 times higher than national average

Extremely high blood pressure that leads to strokes, heart attacks and acute kidney damage, classified as hypertensive emergency, is five times higher in inner-city African-American patients than the national average, according to a recent study co-lead by a Rutgers researcher.

Exercising regularly linked to better eating habits

In the latest evidence that it's worth sticking to your health-focused New Year's resolutions, researchers at the University of Texas at Austin have found that exercising regularly is linked to better eating habits.

Vegan diet helps promote beneficial gut hormones, study finds

A study published in the journal Nutrients finds that a vegan diet helps to promote beneficial gut hormones that are responsible for regulating blood sugar, satiety, and weight.

USC researchers use AI to identify blood-based markers of Alzheimer's disease

Nearly 50 million people worldwide have Alzheimer's disease or another form of dementia. While age is the greatest risk factor for developing the disease, researchers believe most Alzheimer's cases occur as a result of complex interactions among genes and other factors. But those factors and the role they play are not known--yet.

Augmentation of labor with higher doses of oxytocin does not reduce rate of cesarean sections

Delayed labor increases the risk of a cesarean section, even among women who receive oxytocin for augmentation of labor. The rate of cesarean section among first-time mothers is not reduced if the administered dose is doubled either, according to a dissertation from Sahlgrenska Academy at the University of Gothenburg, Sweden.

Community hospitals link arms with prestigious facilities to raise their profiles

After seven years of a vigorous fight, Jim Hart worried he was running out of options. Diagnosed with prostate cancer at age 60, Hart had undergone virtually every treatment — surgery, radiation and hormones — to eradicate it. But a blood test showed that his level of prostate-specific antigen, which should have been undetectable, kept rising ominously. And doctors couldn’t determine where the residual cancer was lurking.
