Bipolar disorder and friendships: How to be there for someone
Bipolar disorder is a mental health condition that can result in extreme shifts in mood. As this may affect how a person thinks, feels, and behaves, it may present challenges that can make it difficult to maintain friendships. Bipolar disorder is a mood disorder that can severely disrupt a person’s life. There are different types of bipolar...
Lilly wins FDA approval of new kind of diabetes drug
Jonathan Gardner Senior Reporter Eli Lilly & Co. The Food and Drug Administration on Friday approved Eli Lilly’s diabetes drug Mounjaro, a first-of-its-kind treatment that can help control patients’ blood sugar and, potentially, help them lose weight as well. Mounjaro, also known as tirzepatide, expands Lilly’s diabetes business, which includes insulins as well as other...
Coronavirus ‘ghosts’ found lingering in the gut
Heidi Ledford Particles of SARS-CoV-2 (blue; artificially coloured) bud from a dying intestinal cell.Credit: Steve Gschmeissner/SPL In the chaos of the first months of the coronavirus pandemic, oncologist and geneticist Ami Bhatt was intrigued by widespread reports of vomiting and diarrhoea in people infected with SARS-CoV-2. “At that time, this was thought to be a...
Clues from Down syndrome hint at new Alzheimer’s finding
For a long time, common diseases (think Alzheimer’s, cancer and other ailments) were thought to arise mostly from molecular or genetic mishaps. But scientists are finding that there seems to be increased involvement of an unexpected culprit: stem cells. Nine years ago, Stanford oncologist Michael Clarke, MD, made a connection between stem cells and Down syndrome: He...
The Molecular Machinery That Delivers Metabolites to Mitochondria
When we eat and then digest a meal, the nutrients and other useful components in the food are broken down—or metabolized—and ultimately make their way to cells throughout the body. Each cell has its own power plant, called the mitochondria, which produces energy for the cell’s various processes as well as other tasks that help keep...
A single hormone directs body’s responses to low-protein diet
PENNINGTON BIOMEDICAL RESEARCH CENTER IMAGE: WHEN THE LIVER DETECTS LOW LEVELS OF PROTEIN, IT ACTIVATES CELLS THAT PRODUCE FGF21 AND RELEASE THE HORMONE INTO THE BLOODSTREAM. FGF21 IS THEN CARRIED TO TARGET CELLS (NEURONS) IN THE BRAIN. THOSE CELLS HIT THE ALARM BUTTON WHEN THEY SEE FGF21, SIGNALING THAT PROTEIN INTAKE IS TOO LOW.THE BRAIN...
Cardiac progenitor cells generate healthy tissue after a heart attack
by Technical University Munich Credit: Pixabay/CC0 Public Domain Following a heart attack, the human body is incapable of repairing lost tissue due to the heart’s inability to generate new muscle. However, treatment with heart progenitor cells could result in the formation of functional heart cells at injured sites. This new therapeutic approach is introduced by...
Researchers develop wireless implantable vascular monitoring system
by Georgia Institute of Technology Woon-Hong Yeo has developed a smarter stent. Credit: Georgia Tech Photo Vascular diseases are public enemy number one: the leading killers worldwide, accounting for nearly a third of all human deaths on the planet. Continuous monitoring of hemodynamics—blood flow through the vascular system—can improve treatments and patient outcomes. But deadly conditions like hypertension...
Feedback disruptors—a new class of therapeutics—throw drug resistance for a loop
by Sarah Stanley, Gladstone Institutes Scientists at Gladstone Institutes have developed a new class of therapeutics that have the potential of transforming treatments for viral diseases. Shown here is Sonali Chaturvedi, first author of the study.
