A recent study reveals a critical link between obesity and type 2 diabetes through the AMPK pathway and leptin hormone. Researchers found that AMPK activation, triggered by leptin, inhibits an enzyme involved in fat metabolism, increasing fat burning.
Researchers discover tumstatin protein inhibits angiogenesis by targeting a specific integrin molecule, preventing the growth of new blood vessels in tumors. The study provides new insights into the mechanism behind tumstatin's anti-angiogenic effects, paving the way for the development of more effective cancer drugs.
Researchers found that embryonic stem cells can survive in damaged heart muscle and improve cardiac function. The study demonstrated significant reduction of MI damage and improvement in left ventricular function, suggesting a potential future treatment option for congestive heart failure.
A clinical trial of 109 patients found that coronary magnetic resonance angiography (MRA) accurately diagnosed coronary artery disease with an accuracy rate of 72% and specificity of 87%. The non-invasive test eliminates radiation exposure, infection risk, and hospital stay time, making it a promising diagnostic tool.
Research suggests that a single enzyme, 11beta hydroxysteroid dehydrogenase type 1 (11 beta HSD-1), is involved in the accumulation of visceral fat and metabolic symptoms. Increasing this enzyme's activity in fat cells leads to obesity, diabetes, and other diseases.
A nationwide survey of over 800 adults found that patients who use both traditional and CAM therapies view their healthcare providers as part of a larger team. More than half of respondents believed CAM therapies were more helpful for certain conditions, but had equal trust in physicians as practitioners.
Researchers identified a region on Chromosome 4 containing genes that contribute to exceptional longevity. This discovery could lead to the development of drugs that mimic centenarians' genetic characteristics, promoting healthy aging.
A recent study found that diabetes markedly raises the long-term death rate of people with heart attacks, especially women. The study followed 1,935 men and women hospitalized for a heart attack for an average of 3.7 years after their initial hospitalization.
Researchers at Beth Israel Deaconess Medical Center found that fat cells can trigger insulin resistance in muscle and liver, leading to type 2 diabetes. The study, published in Nature, reveals a potential new target for diabetes treatment and prevention by disrupting the communication between fat cells and other tissues.
Researchers at Beth Israel Deaconess Medical Center found that the right hemisphere helps people recognize themselves in pictures. The study used morphed images blending a patient's face with famous faces and showed that patients' right brains could recognize their own faces even when anesthetized, but not when only the left brain was ...
Researchers at Beth Israel Deaconess Medical Center developed an AIDS vaccine that harnesses "killer" T cells to suppress the virus and prevent clinical disease in monkeys. The vaccine showed significant success in boosting CD8 cytotoxic T lymphocytes, which can attack and contain HIV-infected cells.
A study by Beth Israel Deaconess Medical Center found that people who continued to smoke after undergoing balloon angioplasty and other procedures had lower quality-of-life scores compared to non-smokers and quitters. The researchers analyzed data from 1,432 patients and found a significant impact on physical and mental health measures.
A study published in the Journal of the American Medical Association found that nearly 90% of high-risk patients received antibiotic instructions, while only 60% of moderate-risk patients did. The study also revealed that 25% of low-risk patients incorrectly received antibiotics and 13% chose not to take them.
William Cohn, a cardiothoracic surgeon at Beth Israel Deaconess Medical Center, has invented the Cohn Cardiac Stabilizer, allowing coronary artery bypass surgery to be performed on a beating heart. The device has advanced the state of the art and will speed patient recovery and save lives.
A large randomized clinical trial shows that self-hypnotic relaxation techniques can decrease pain medication use, reduce operating room time, and improve vital signs during surgery. The study's findings suggest that hypnosis can be a safe and effective method for reducing anxiety and pain in patients undergoing invasive procedures.
A study published in Annals of Neurology reveals that people with migraines experience extreme skin sensitivity, which may explain why current medications are ineffective. The researchers suggest treating migraines as soon as the pain starts and developing new treatments targeting spinal cord neurons.
A Boston study found that marijuana smoke increases the risk of a heart attack by nearly five-fold within the first hour, but the effect decreases rapidly over time. The study used a multicenter design and included 3,882 patients who survived heart attacks.
Researchers at Beth Israel Deaconess Medical Center have discovered a potent new substance, canstatin, that inhibits the growth of tumors by blocking the formation and growth of new blood vessels. The naturally occurring protein is effective in both prostate and renal cancer models.
Researchers have found that PR39 promotes angiogenesis by blocking the degradation of a key transcription factor, HIF-1alpha. The newly formed vessels were fully functional in mice studies, offering a promising tool for treating coronary artery disease and peripheral vascular disease.
A recent study published in Annals of Internal Medicine found that illness severity, rather than age, is a key predictor of death among seriously ill patients. The research analyzed data from over 9,000 hospitalized patients and found that those with the sickest conditions were at highest risk of dying within six months.
Researchers discovered HIV can replicate in resting T cells, previously thought to be uninfected. The virus spreads quickly through activated T cells as well, but these infected cells are harder to reach with current therapies.
Research found that positive words associated with aging, such as 'wise' and 'astute', increased walking speeds by 9% in older individuals. This study suggests that minimizing negative stereotypes about aging can lead to improved physical function and independence.
Researchers have discovered a reversible lipid imbalance that may be responsible for the common symptoms of cystic fibrosis. Administration of DHA corrected the imbalance and reversed signs of cystic fibrosis in mice with the genetic defect.
