Medical Xpress / Tracing schizophrenia's origins: Study maps chromatin accessibility in postmortem brain tissue
Schizophrenia is a severe neuropsychiatric disorder characterized by hallucinations, false beliefs about oneself or the world (i.e., delusions), and other disruptions in thought, emotion and perception. Recent genetic studies ...
Medical Xpress / Do fatalistic attitudes affect clinical outcomes in type 2 diabetes?
University of Wisconsin-Milwaukee and University at Buffalo investigators report that diabetes fatalism is associated with lower mental health-related quality of life over 12 months in African American adults with poorly ...
Medical Xpress / Disrupting bacterial 'chatter' could tip the balance for better oral health
Like all living things, bacteria adapt to survive. Over time, bacteria have been developing resistance to common antibiotics and disinfectants, which poses a growing problem for health care and sanitation. However, many species ...
Medical Xpress / Gene 'switch' reverses Alzheimer's risk in experimental model
University of Kentucky researchers have developed a new experimental model that could point the way toward more effective Alzheimer's disease treatments by targeting one of the brain's most important genes for risk and resilience.
Medical Xpress / Reviving exhausted immune cells boosts tumor elimination
A new study has discovered a molecular signal that tumors exploit to exhaust the T cells meant to destroy them—and how silencing that signal could revive the body's immunity.
Medical Xpress / A unified model of memory and perception: How Hebbian learning explains our recall of past events
A collaboration between SISSA's Physics and Neuroscience groups has taken a step forward in understanding how memories are stored and retrieved in the brain. The study, recently published in Neuron, shows that distinct perceptual ...
Medical Xpress / Evidence builds for disrupted mitochondria as cause of Parkinson's
For decades, scientists have known that mitochondria, which produce energy inside our cells, malfunction in Parkinson's disease. But a critical question remained: do the failing mitochondria cause Parkinson's, or do they ...
Medical Xpress / Medications change our gut microbiome in predictable ways, research reveals
Our gut microbiome is made up of trillions of bacteria and other microbes living in our intestines. These help our bodies break down food, assist our immune system, send chemical signals to our brain, and potentially serve ...
Medical Xpress / Next-generation microbiome medicine may transform Parkinson's treatment
The age-old advice to "trust your gut" could soon take on new meaning for people diagnosed with Parkinson's disease, thanks to a creative feat of bioengineering by researchers in the University of Georgia's College of Veterinary ...
Medical Xpress / CRISPR breakthrough reverses chemotherapy resistance in lung cancer
In a major step forward for cancer care, researchers at ChristianaCare's Gene Editing Institute have shown that disabling the NRF2 gene with CRISPR technology can reverse chemotherapy resistance in lung cancer. The approach ...
Medical Xpress / Scientists identify two key targets of common cold virus
Scientists were pleased when they learned more about how the common cold gains a foothold in the body, identifying key cellular checkpoints that are important targets of the virus.
Medical Xpress / How the gut builds long-lasting immunity after viral infections
A new study led by University of Toronto researchers has shown that immune cells in the gut follow an atypical pathway to produce antibodies that provide long-term protection against viruses.
