Discovery of molecular origins of a heart beat

Researchers have found that molecular origins of a heart beat. They have found the proteins that make up tiny sodium channels in the tissues of the heart that can help generate the heart beats. The results of the study titled, “Structure of the Cardiac Sodium Channel” was published yesterday 19th of December 2019 in the journal Cell.

UTHealth researchers receive $3.1 million NIH grant to address youth vaping epidemic

As e-cigarette use by young people reaches epidemic proportions, researchers at The University of Texas Health Science Center at Houston have received a $3.1 million grant from the National Institutes of Health to conduct the first-ever assessment on the long-term results of a nationwide nicotine vaping prevention program for youth called CATCH My Breath.

Using bacterial nano-syringes as drug transporters in medicine

Pathogens can use a range of toxins to damage their host organism. Bacteria, such as those responsible for causing the deadly Plague, use a special injection mechanism to deliver their poisonous contents into the host cell.

Skip the sweet treats to avoid holiday blues, study suggests

If you're prone to depression, this holiday season you might want to say "bah humbug" to offers of sugar plum pudding, caramel corn and chocolate babka.

Scientists use novel technology for opening blood-brain barrier with implantable ultrasound

One of most potent drugs for treatment of glioblastoma, the most deadly type of brain tumor, can't be used in patients because of two problems. First, it can't reach its target because it's blocked by the blood-brain barrier, a microscopic structure that protects the brain from toxins in the blood. And the conventional formulation for this drug is toxic to the brain.

Experimental immunotherapy can put patients with relapsed or refractory lymphoma into remission

A new, experimental immunotherapy can put patients with B-cell non-Hodgkin lymphoma (NHL) that is resistant to or has come back after multiple other therapies, including CAR T therapy, into remission.

Mechanical stress can interrupt bacteria’s ability to survive toxin exposure

A random conversation between two Cornell researchers at a child's birthday party led to a collaboration and new understanding of how bacteria resist toxins, which may lead to new tools in the fight against harmful infections.

FDA-approved drug repairs gut leakiness associated with ulcerative colitis

A research team led by biomedical scientists at the University of California, Riverside, has found that a drug approved by the FDA to treat rheumatoid arthritis and ulcerative colitis can repair permeability defects in the gut's epithelium.

Researchers move one step closer to understanding complex physiology of CKD patients

Researchers have further analyzed a known signaling pathway they believe brings them one step closer to understanding the complex physiology of patients with chronic kidney disease (CKD), which might provide a path to new treatment options.

Climate change and children’s health

UNICEF says that climate change is posing an immense challenge to the health of children worldwide. Though children commonly have the least to do with the actions and attitudes that lead to climate change, they are the ones who will have to bear the brunt of it.

Strong beers that contain gut-friendly bacteria may help fight obesity

Drinking a strong type of beer, particularly a Belgian one, can help combat obesity, promote a good night’s sleep, and may help you live longer, a new study found.

Changes in placenta could mean males born to older mothers more prone to heart problems

A new study in rats shows that older mother rats develop poorer placentas which are in turn related to later risk of heart problems in their male offspring. The study, published in the journal Scientific Reports, shows that both male and female offspring are smaller in size when the mother is older. However, the placental development in older mothers with male fetuses is especially impaired, leading to worse placental function. As a result, heart problems are more common in later life in these offspring, as is high blood pressure.

Placenta changes in older mothers linked to greater odds of heart problems in male offspring

Placenta changes could mean male offspring of older mums more likely to develop heart problems in later life, rat study finds.

Additives in vaping products produce higher aerosol toxins, study finds

The vaping industry is filled with unknowns. Those unknowns are leading to more questions as the number of users dealing with injuries, or in some cases, death, continues to rise.

Article reveals new mechanism of programmed aging

Nature has sentenced humans to an inevitable death from the time of birth; the natural instrument of execution is the aging process. According to modern scientific notions, only two root causes of aging can be: stochastic physiological damage or the implementation of a special genetic program in the body.

Researchers assess safety of conditionally immortalized cells for bioartificial kidney application

Here, the research team assessed the safety of conditionally immortalized proximal tubule epithelial cells for bioartificial kidney application, by using in vitro assays and athymic nude rats.

Researchers discover new pathway to 'reprogram' killer cells

Killer cells of the immune system detect and kill infected cells or cancer cells. Researchers at the Institute of Pathology at the University of Bern have now discovered that the mechanism by which certain immune cells kill their target cells can also be used to control the killer cells themselves.
