Scientists reveal that the adiponectin hormone plays a key role in increasing lifespan by burning fatty acids instead of glucose, reducing free radical damage. Meanwhile, researchers identify a new protein in spider silk, which could revolutionize our understanding of its mechanical properties.
Researchers at the University of Pittsburgh School of Medicine have found that Botox injections can reduce prostate size and alleviate urinary tract symptoms in men with benign prostatic hyperplasia (BPH). Up to 73% of patients experienced improved quality of life and reduced symptoms for up to a year after treatment.
Researchers found significantly less salivary gland damage in a group treated with green tea extract, suggesting a reduction of Sjogren's Syndrome symptoms like dry mouth. Green tea's EGCG component may also suppress inflammation and turn on the body's defense system against TNF-alpha.
Researchers studied spider silk production, discovering how polymers align to create a strong fiber. They aim to develop artificial spider silk for various applications, including tendons and bulletproof vests.
Targeted overexpression of HSP25 protects salivary gland function by maintaining gland weight, salivary flow rate, and salivary fluid composition. HSP25 also preserves expression of aquaporin 5, crucial for water transport in salivary glands. These findings suggest a novel radioprotective strategy against radiation-induced salivary gla...
Researchers found Botox injections to improve urinary tract symptoms and quality of life in men with enlarged prostates. The treatment reduced prostate size through apoptosis, improving urine flow and decreasing residual urine.
Researchers found that cystic fibrosis airway glands have defective gland secretion due to a lack of fluid secretion from glands. The study suggests that loss of CFTR-mediated fluid secretion is the main cause of mucus buildup in cystic fibrosis.
Aplysia sea slugs use a system to mix and release chemicals, including L-lysine, L-arginine, and an enzyme protein called escapin, to defend against predators. The secretion stimulates feeding behaviors in some animals but deters it in others, and may also have antimicrobial properties.
University of Washington researchers found a gland in fruit flies that assesses the fly's size and sends hormonal signals to initiate metamorphosis. By genetically manipulating the prothoracic gland, scientists could alter the size at which the fly would reach adulthood, providing new insights into an organism's growth process.
Researchers have identified a rare genetic change on the X chromosome that causes XLHPT, a condition affecting male blood calcium levels and parathyroid hormone secretion. The study's findings may lead to new treatments for osteoporosis, a bone-weakening condition in the elderly.
Two studies found that manipulating ecdysone release timing and Ras activity regulates fruit fly development. The prothoracic gland acts as a size-sensing tissue, determining when metamorphosis should occur.
Researchers suggest that the parathyroid gland evolved from the gills of ancestral marine creatures to regulate calcium levels in land-living animals. The discovery supports the idea that humans and other tetrapods share a common evolutionary history with fish.
Researchers at Duke University have been studying ring-tailed lemurs' scent language to understand their complex chemical communications. The scientists found that lemurs use 'scentences', combinations of scents extending their chemical messages, and identified specific compounds in their scent profiles.
Researchers at SLU School of Medicine discovered a new drug, Cinacalcet, that successfully treated hyperparathyroidism, a common side effect of kidney disease. The treatment works by fooling the parathyroid glands into thinking calcium levels are higher than they actually are.
Researchers at USC have created a transgenic mouse with an overexpressed noggin gene, resulting in increased hair follicles, thicker fur, and additional whiskers. The study also reveals unusual changes to the mice's eyes, feet, and genitalia, challenging the distinction between normal and abnormal variations.
Researchers find that one species of Brazilian stingless bee uses an abbreviated scent trail to communicate food location, avoiding broadcasting information to competitors. The unique trail has a teardrop shape and scent concentration that allows bees to pinpoint specific food sources.
The EFT test uses two new biochemical markers, cyclin E and p27, to evaluate endometrial health and predict implantation success. A normal EFT result indicates a healthy endometrium receptive to embryo attachment, improving fertility diagnosis and treatment outcomes.
The study identified the gene responsible for producing ear wax as being located on chromosome 16, near another gene linked to paroxysmal kinesigenic choreoathetosis. This discovery may shed light on the development of apocrine glands and their secretory products.
A new minimally invasive radio-guided parathyroidectomy (MIRP) technique allows surgeons to remove parathyroid glands with fewer complications, reducing surgery time from several hours to just 30 minutes. This outpatient procedure also enables patients to go home within a few hours, compared to days of hospitalization.
A new technology developed by Dr. Lawrence Larsen at Sandia National Laboratories can treat benign prostatic hyperplasia (BPH) without surgery, reducing side effects and costs. The non-invasive procedure uses radio frequency energy to kill excess cells, shrinking the prostate gland and alleviating urinary obstruction and pain.
A new study by Johns Hopkins Medicine shows that minimally invasive surgery to remove parathyroid tumors is safe and effective, with a significantly shorter hospital stay and reduced hospital charges compared to traditional open surgery. The procedure also reduces the risk of complications, such as vocal nerve injury.
Scientists have pinpointed a protein called plethodontid receptivity factor (PRF) that directly influences female receptivity in salamanders, shortening the courtship time by 15%,. This discovery highlights the importance of pheromones in survival and provides insights into the evolution and mechanism of action of these complex chemicals.
Researchers found that the thymus gland remains functional in adults and can produce new T cells after HIV infection is suppressed. After receiving HAART, HIV-infected individuals showed a rapid increase in T-cell production.
Researchers found that mating is more harmful to females than egg laying, with costs imposed by males leading to female survival and reproductive value depression. In contrast, egg production has a minimal impact on female fitness under certain conditions.
