Trial demonstrates early AI-guided detection of heart disease in routine practice

Posted: 06 May 2021 11:21 AM PDT

Heart disease can take a number of forms, but some types of heart disease, such as asymptomatic low ejection fraction, can be hard to recognize, especially in the early stages when treatment would be most effective.

New evidence links gut bacteria and neurodegenerative conditions

Researchers speed identification of DNA regions that regulate gene expression

Posted: 06 May 2021 09:58 AM PDT

Scientists have developed a highly efficient method to address a major challenge in biology -- identifying the genetic 'switches' that regulate gene expression.

Independent evolutionary origins of vertebrate dentitions

Posted: 06 May 2021 09:58 AM PDT

The origins of a pretty smile have long been sought in the fearsome jaws of living sharks which have been considered living fossils reflecting the ancestral condition for vertebrate tooth development and inference of its evolution. However, this view ignores real fossils which more accurately reflect the nature of ancient ancestors.

Children likely to be pleading guilty when innocent

Posted: 06 May 2021 09:58 AM PDT

Young people need additional support and protection in the criminal justice system because they are more susceptible to pleading guilty when innocent, a new study argues.

The origin of reproductive organs

Posted: 06 May 2021 09:57 AM PDT

Early in fetal development, a mass of cells known as the bipotential gonad has the possibility of giving rise either to ovaries or testes, reproductive organs that contribute to many of the characteristics that define a person's sex. In a new study, researchers pinpoint the origins of that precursor gland.

Research breakthrough in the fight against cancer

Posted: 06 May 2021 09:57 AM PDT

Researchers have engineered a nanoparticle that has the potential to revolutionize disease treatment, including for cancer.

Study confirms racial differences in response to prostate cancer treatment

Posted: 06 May 2021 07:55 AM PDT

A study designed to enroll an equal number of Black and white men with advanced prostate cancer confirms key findings that have been evident in retrospective analyses and suggest potential new avenues for treating Black patients who disproportionately die of the disease.

New method identifies tau aggregates occurring in healthy body structures

Posted: 06 May 2021 07:54 AM PDT

Researchers used microscopy and machine learning to distinguish tau protein aggregates occurring as part of healthy functions from those occurring in disease.

Men with chest pain receive faster, more medical attention than women

Posted: 06 May 2021 07:54 AM PDT

Among younger adults visiting the emergency department for chest pain, women may be getting the short end of the stick. Compared with men of similar age, women were triaged less urgently, waited longer to be seen, and were less likely to undergo basic tests or be hospitalized or admitted for observation to diagnose a heart attack, according to new research.

Mental health may play big role in recovery after a heart attack

Posted: 06 May 2021 07:54 AM PDT

Young and middle-aged adults who reported severe psychological distress -- such as depression or anxiety -- after suffering a heart attack were more than twice as likely to suffer a second cardiac event within five years compared with those experiencing only mild distress, according to a new study.

Alcohol in moderation may help the heart by calming stress signals in the brain

Posted: 06 May 2021 07:54 AM PDT

Moderate alcohol intake -- defined as no more than one alcoholic drink for women and two for men per day -- has been associated with a lower risk of dying from cardiovascular disease when compared with individuals who abstain from drinking or partake in excessive drinking, according to a new study.

Have high blood pressure? You may want to check your meds

Posted: 06 May 2021 07:54 AM PDT

Nearly 1 in 5 adults with high blood pressure, a leading risk factor for heart disease and stroke, also take a medicine that could be elevating their blood pressure, according to new research. The results underscore the need for patients to routinely review all of the medications they take with their care team, including those available over the counter, to make sure none could be interfering with blood pressure lowering efforts.

Exercise aids the cognitive development of children born preterm

Posted: 06 May 2021 07:54 AM PDT

A premature start in life can cause problems even into teenage years. A study indicates that training motor skills in these children helps even when they are older.

Epilepsy research reveals why sleep increases risk of sudden death

Posted: 06 May 2021 07:54 AM PDT

To understand the effect of sleep seizures, researchers monitored the brain and heart activity of people with epilepsy as they slept.

Novel non-coding RNAs regulating blood vessel formation

Posted: 06 May 2021 07:54 AM PDT

Researchers have discovered previously unknown non-coding RNAs (ncRNAs) involved in regulating the gene expression of vascular endothelial growth factors (VEGF), the master regulators of angiogenesis.

Better way to determine safe drug doses for children

Posted: 06 May 2021 07:53 AM PDT

To make drugs and their development safer for children, researchers have developed a method that could help determine safe drug doses more quickly. In their study, the team created a model of how organs develop that is more data-driven and consequently less prone to bias.

Cell cytoskeleton as target for new active agents

Posted: 06 May 2021 07:53 AM PDT

Through a unique combination of computer simulations and laboratory experiments, researchers have discovered new binding sites for active agents - against cancer, for example - on a vital protein of the cell cytoskeleton. Eleven of the sites hadn't been known before.

Defective epithelial barriers linked to two billion chronic diseases

Posted: 06 May 2021 07:53 AM PDT

Humans are exposed to a variety of toxins and chemicals every day. According to the epithelial barrier hypothesis, exposure to many of these substances damages the epithelium, the thin layer of cells that covers the surface of our skin, lungs and intestine. Defective epithelial barriers have been linked to a rise in almost two billion allergic, autoimmune, neurodegenerative and psychiatric diseases.

Possible novel migraine therapy

Posted: 05 May 2021 02:49 PM PDT

By discovering a potential new cellular mechanism for migraines, researchers may have also found a new way to treat chronic migraine.

Cardiovascular disease could be diagnosed earlier with new glowing probe

Posted: 05 May 2021 10:05 AM PDT

Researchers have created a probe that glows when it detects an enzyme associated with issues that can lead to blood clots and strokes.

From yeast to hypha: How Candida albicans makes the switch

Posted: 05 May 2021 10:05 AM PDT

A protein called Sir2 may facilitate C. albicans' transition from ovoid yeast to thread-like hypha. C. albicans cells that were missing the Sir2 gene were less likely to form true hyphae in lab experiments than cells of the same species that had that gene.

Novel switch found in proteins with wide-ranging implications for medical treatments

Posted: 05 May 2021 10:05 AM PDT

Proteins perform a vast array of functions in the cell of every living organism with critical roles in biological processes. There are numerous chemical switches that control the structure and the function of proteins, which were thought to be well understood: so a team of researchers were surprised to discover a completely new on/off switch that seems to be a ubiquitous regulatory element in proteins in all domains of life.

New guidelines for schools recommend against food bans
