Philadelphia, May 19, 2021 - A multidisciplinary team of researchers from Children's Hospital of Philadelphia (CHOP) and the Perelman School of Medicine at the University of Pennsylvania (Penn) showed how the "batteries" of cells are highly implicated in whether patients with the chromosome 22q11.2 deletion syndrome develop schizophrenia. The results of the study may eventually lead to targeted prevention and treatment strategies for patients with the condition. The findings were published today in JAMA Psychiatry. 22q11.2 deletion syndrome (22q) is ...

The common skin disease atopic eczema (AE) impacts heavily on the life quality and general health of sufferers. Researchers at Karolinska Institutet in Sweden have now evaluated its treatment with internet-delivered cognitive behavioural therapy (iCBT). The study suggests that patients feel better after iCBT compared with a control group who received only traditional treatment. The results, which are published in JAMA Dermatology, might eventually make important care available to a large patient group. "We've carried out a promising pilot study but were still surprised at how effective internet-delivered CBT ...

A pioneering new study led by UCL scientists has revealed, for the first time, a layer of genetic material involved in controlling the production of tau; a protein which plays a critical role in serious degenerative conditions, such as Parkinson's and Alzheimer's disease. The international research, conducted in mice and cells, also revealed this material is part of a larger family of non-coding genes* which control and regulate other similar brain proteins, such as beta-amyloid associated with Alzheimer's and alpha-synuclein implicated in Parkinson's disease and Lewy body dementia. Researchers say the breakthrough findings, ...

Base editing is a novel gene editing approach that can precisely change individual building blocks in a DNA sequence. By installing such a point mutation in a specific gene, an international research team led by the University of Zurich has succeeded in sustainably lowering high LDL cholesterol levels in the blood of mice and macaques. This opens up the possibility of curing patients with inherited metabolic liver diseases. Lipoproteins are complex particles that deliver fat molecules to all tissues of the body through the blood system, supplying energy to the cells. One such lipoprotein, the low-density lipoprotein (LDL), can transport thousands of fat molecules, such as cholesterol, per particle. High levels of LDL in the blood are clinically associated with an ...

Wednesday 19 May 2021 - New research published today sheds important light on how the production of a key protein in the brain is controlled, which could pave the way for new treatments for a wide range of neurological conditions. In a study part-funded by Parkinson's UK, researchers investigated a section of genetic material known as antisense long non-coding RNA (lncRNA), which helps fine-tune the production of the protein tau inside brain cells. This precision in tau regulation is crucial for smooth functioning of the nerve cells. Understanding the mechanism ...

Unbound nickel atoms and other heavy elements have been observed in very hot cosmic environments, including the atmospheres of ultra-hot exoplanets and evaporating comets that ventured too close to our Sun or other stars. A new study conducted by JU researchers reveals the presence of nickel atoms in the cold gasses surrounding the interstellar comet 2I/Borisov. The team's finding is being published in Nature on 19 May 2021. Interstellar comets and asteroids are precious to science because, unlike millions of minor bodies that formed in our Solar System, they originate from distant planetary systems. Until very recently, the existence of such cosmic vagabonds has merely ...

HOUSTON - (May 19, 2021) - A new study from researchers at Rice University has found that bodily inflammation after the death of a spouse can predict future depression. "Inflammation and future depressive symptoms among recently bereaved spouses" will appear in the June 2021 edition of the journal Psychoneuroendocrinology. Lead author Lydia Wu, a Rice psychology graduate student, and Christopher Fagundes, associate professor of psychology and principal investigator for the Biobehavioral Mechanisms Explaining Disparities (BMED) lab at Rice, led the study. The research team evaluated 99 people who lost their spouses within 2-3 months of the study on a number of factors, including physical ...

PITTSBURGH, May 19, 2021 - Specialized immune cells that accumulate in the brain in the days and weeks after a stroke promote neural functions in mice, pointing to a potential immunotherapy that may boost recovery after the acute injury is over, University of Pittsburgh School of Medicine neurologists found. The study, published today in the journal Immunity, demonstrated that a population of specialized immune cells, called regulatory T (Treg) cells, serve as tissue repair engineers to promote functional recovery after stroke. Boosting Treg cells using an antibody complex treatment, ...

The yeast Candida albicans can cause itchy, painful urinary tract and vaginal yeast infections. For women in low-resource settings who lack access to healthcare facilities, these infections create substantial social and economic burdens. Now, researchers reporting in ACS Omega have developed color-changing threads that turn bright pink in the presence of C. albicans. When embedded in tampons or sanitary napkins, they could allow women to quickly and discreetly self-diagnose vulvovaginal yeast infections, the researchers say. According to the Mayo Clinic, about 75% of women will experience a yeast infection, or vulvovaginal candidiasis, at least ...

Researchers have found the elusive genetic element controlling the elongated grains and glumes of a wheat variety identified by the renowned botanist Carl Linnaeus more than 250 years ago. The findings relating to Polish wheat, Triticum polonicum, could translate into genetic improvements and productivity in the field. Wheat, in bread, pasta, and other forms, is a vital energy and protein source for humans. Each individual grain is nestled within the glumes and other leaf-like organs called lemma and palea which affect the grain's final size, shape, and weight. Characterised by Linnaeus in 1762, Polish wheat has long grains, glumes, ...
