Medical Xpress / An antibody-based drug triggers rare inflammatory eye problems in macular degeneration patients
A drug approved in 2019 for macular degeneration apparently caused rare retinal side effects because of its interactions with the human immune system, two new studies have concluded.
Medical Xpress / Scientists shed new light on two proteins that exacerbate the progression of Parkinson's disease
Two proteins may be intimately linked to the progression of Parkinson's disease, a relentless and disabling neurodegenerative disorder that affects millions of people around the world.
Medical Xpress / Study: Experimental COVID shot made via egg-based technology elicits higher antibody proportion than mRNA vax
An experimental COVID-19 vaccine produced with technology based on a decades-old method, elicited virus-neutralizing antibodies in higher proportion than the amount induced by mRNA immunizations, a Phase 1 clinical trial ...
Medical Xpress / Human feces and urine contain a motherlode of health data: 'Smart toilets' detect daily fluctuations, serious disease
A disease-detecting toilet capable of a range of monitoring and surveillance activities could soon be reality, and while the device may test for everything from how fast your urine flows to reporting on your vital signs, ...
Phys.org / Scientists decipher how non-resistant forms of Staph aureus thwart antibiotics, almost like a superbug
Staphylococcus aureus (S. aureus) has a slew of surprises in its bag of dirty tricks and among the most puzzling has been the ability of non-resistant forms of the bacteria to emerge unscathed, even after exposure to high ...
Medical Xpress / A flurry of RSV vaccine research may result in a protective immunization in the not-too-distant future
A new analysis of how the immune system responds to both older and newer investigational vaccines for respiratory syncytial virus—RSV—will help inform the ultimate translation of an immunization from the laboratory to actual ...
Medical Xpress / Evolutionary history of SARS-CoV-2 leads to a universal vaccine already being tested in animal models
By taking inspiration from the evolutionary history of SARS-CoV-2 itself, scientists in China have crafted a new vaccine that, at least in animal models, provides protection against omicron and an array of its subvariants.
Medical Xpress / Experimental vaccine for deadly Marburg virus guards against infection with just a single dose
An experimental vaccine for Marburg virus—a deadly cousin of the infectious agent that causes Ebola—can protect large animals from severe infections for up to a year with a single shot, scientists have found in a new study.
Medical Xpress / How cancer cells die: Scientists explore new pathways of pyroptosis, killer kin of apoptosis
For anyone who has taken Biology 101, the concept of apoptosis—programmed cell death—is taught early in the course. You can't understand the life cycle of a cell without learning how they die.
Medical Xpress / An mRNA vaccine strategy under study to fight the flu—as a shot and intranasal spray
Messenger RNA vaccine technology, once an arcane area of research, became household terminology because of the COVID-19 pandemic, and now scientists are working on an mRNA flu vaccine strategy that, at least in this study, ...
Medical Xpress / High fat ketogenic diet envisioned as potential life-saving therapy to combat low platelets in cancer patients
A high-fat diet may combat low platelet counts in the blood caused by chemotherapy, according to preliminary research, which suggests that a ketogenic eating plan may be a nontoxic, low-cost and high-benefit addition to cancer ...
Medical Xpress / Pulmonary arterial hypertension is incurable but animal model study suggests an experimental drug may be effective
An experimental drug that is already in clinical trials for other diseases could disrupt a positive feedback loop that exacerbates pulmonary arterial hypertension, a dangerous and rapidly fatal condition for which there is ...
Medical Xpress / The secret lives of T cells: They derive energy from a master regulator that has been poorly understood, until now
T cells aren't the first immune forces on the scene, they arrive after being alerted by other immune system warriors that a microbe has invaded or a cancer has silently seeded.
Medical Xpress / Microbiome: Scientists highlight role of harmful gut bacteria in fever afflicting cancer patients
An altered gut microbiome is an unexpected cause of fever afflicting many patients undergoing chemotherapy, according to scientists who've also discovered that poor appetite during cancer treatment may trigger the biological ...
Medical Xpress / Breakaway breast cancer cells can travel to the brain: Scientists plot path in quest to block entry
One of the most puzzling—and devastating—aspects of cancer is its potentially lethal wanderlust, the spread of the disease from a primary tumor to a new and distant site.
