Loss of Y Chromosomes in Older Men Elevates Heart Disease Risk, Study Finds

A new study has found that older men losing the Y chromosome in their white blood cells as they age can heighten their risk of death from cardiovascular illnesses and cause severe heart problems. This genetic change, which is scientifically referred to as mosaic Loss of y or mLOY, impacts about 20% of men aged 60 and 40% of those aged 70 and above. The study was carried out by researchers at Sweden’s Uppsala University and the University of Virginia. It was led by Professor Kenneth Walsh of the School of Medicine at the University of Virginia and Associate Professor…

Study Reveals Proteins That Can Trigger Immune System Malfunction

At least 20 million Americans live with autoimmune disorders, but there’s still much we don’t know about these conditions. The disorders usually occur when, for some reason, the immune system goes haywire and begins to attack healthy tissue. In addition to not knowing exactly what causes autoimmune disorders, we still haven’t figured out a way to cure them. Recently, however, researchers studying immune disorders discovered a novel method of triggering the immune system via certain proteins. This discovery could provide scientists with the chance to know more about autoimmune conditions such as lupus and scleroderma. Investigators from Weill Cornell Medicine…

Study Highlights New Insights on Neurological Autoimmune Illnesses

UT Southwestern researchers recently reported that they had used cryoelectron microscopy to obtain the image of an auto-antibody that had bound itself to the surface receptor of a nerve cell. This discovery shows the mechanism behind neurological autoimmune illnesses and may be useful in the development of novel therapies for autoimmune diseases. Autoimmune illnesses are disorders that cause an individual’s immune system to mistakenly attack their body. These illnesses reduce the body’s ability to fight germs such as viruses and bacteria, which in turn, makes individuals susceptible to infections. Common autoimmune illnesses include systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis,…

Preclinical Study Uncovers Potential Key to Treating Deadly Brain Tumors

A new study has found an alternative approach that would make immunotherapy treatments more effective when treating brain tumors. Immunotherapy drugs are usually used to treat a range of cancers. However, glioblastoma multiforme, which is a fatal type of cancer, remains resistant to this revolutionary treatment because the immune system finds it hard to detect and target these tumors, allowing them to grow undisturbed. Researchers have been looking for ways to treat this deadly cancer whose tumors are usually hidden behind the blood-brain barrier. This location hinders drugs from crossing into the central nervous system’s fluid. For their research, the…

Scientists Identify Gene Behind Pediatric Bone Cancer

Scientists at the Lineberger Comprehensive Cancer Center, University of North Carolina have found that the OTUD7A gene impacts Ewing sarcoma development. Ewing sarcoma is a type of cancer that develops primarily in children and affects bones or tissues surrounding the bones. Figures show that roughly 250 young adults and children are diagnosed with this rare cancer annually in the United States. Of this number, about one-half eventually succumb to the illness, which points to the need for better treatments. The researchers, who collaborated with Atomwise Inc. on this study, published their findings in the “Advanced Science” journal. Pengda Liu, co-lead…

Study Maps How Brain Changes During Treatment for Depression

New research has mapped how an individual’s brain changes as they undergo treatment for depression. The study, which was carried out by scientists from the University of British Columbia, was focused on finding out what happened in the brain when a person underwent repetitive transcranial magnetic stimulation. This noninvasive treatment uses magnetic fields to stimulate nerve cells in an individual’s dorso-lateral prefrontal cortex. This region of the brain is involved in mood regulation. This particular treatment is usually administered when other treatment strategies, such as drugs, haven’t effectively helped a patient manage their depression. Various studies have found that antidepressants…

Online Companies Offering Mental Health Services Come Under Spotlight

The need for therapists in the United States is currently at an all-time high, with the latest data from the CDC showing about 40% of adults in the country are struggling to find help for their substance abuse or mental health issues because of a therapist shortage. With no physical providers of the services they seek nearby, most are turning to online sources to meet their needs. Numerous digital mental health companies, such as BetterHelp, which offers access to therapy sessions, have been launched these last few years. These companies often receive backing from venture capital firms and provide a…

Study Finds That Sex, Ethnicity May Impact Risk of Suicide After Concussion

Traumatic brain injuries are among the most difficult injuries to recover from. On top of causing issues such as speech difficulties and problems with logic, studies have found that individuals who sustain long-lasting symptoms from their injuries are more likely to develop mental health problems, including post-traumatic stress disorder (PTSD), depression and suicidal thoughts. Up to 30% of those who survive brain injuries go on to develop post-concussion syndrome, a condition that refers to long-term symptoms after a concussion. Common symptoms of post-concussive syndrome include headaches, brain fog, nausea, blurry vision and memory problems. An estimated 80% of concussion patients…

New Study Finds Some Viruses Can Make You Tastier to Mosquitoes

Mosquitoes aren’t just loud and annoying, they take hundreds of thousands of lives per year by spreading diseases such as malaria, dengue fever, yellow fever and Zika. Researchers have now discovered a kind of cyclical relationship between mosquitoes and mosquito-borne viruses, including dengue fever and the Zika virus. The researchers found that once these viruses have infected humans and mice, they alter their scent and make them more attractive to mosquitoes. Attracted by your altered scent, the deadly bugs gorge on your infected blood and transport the viruses to their next victim. Once the new victim is infected, the cycle…

Researchers Believe Seasonal Allergies Are Worsening

Have you noticed that your pollen allergies are getting worse by the season? You’re not alone. Scientists from Columbia University Irving Medical Center have revealed that outdoor allergies have been getting worse. Physicians across the country say the past few allergy seasons have been more severe as historically high numbers of people sought treatment for allergy symptoms, including itchy eyes, sneezing and running noses. David A Gudis, an ear, nose and throat doctor at Columbia is certain that seasonal allergies are becoming more prevalent. He states that pollen allergies such as hay fever can have serious ramifications for some people…
