Scientists developed a modern intelligent drug that inhibits platelet activity at cool temperatures, preventing blood clots during therapeutic hypothermia. The new drug loses its function when the body is rewarmed, minimizing bleeding problems.
A new study reveals that developing countries are increasing their own health spending, but international aid is sometimes replacing this funding in low-income countries. Channelling aid through NGOs can actually increase government health spending, highlighting the need for better transparency and accountability.
Research from Kansas State University found that businesses can create different marketing approaches for various groups based on the type of relationship they seek with customers. Online retailers should focus on enhancing trustworthiness through measures like Better Business Bureau association and secure data protection.
The US Department of Homeland Security is developing portable water purification systems to address the global issue of dirty water, which claims over a million lives annually. Several companies are participating in the SECURE program, creating self-contained and self-powered systems that can be used in emergency situations.
A new study found that developing countries spend more on healthcare than they receive in foreign aid, with sub-Saharan Africa being an exception. The researchers recommend improving transparency and accountability in financial reporting to strengthen the effectiveness of health aid systems.
Researchers at the University of Texas M. D. Anderson Cancer Center have developed a new way to predict prognosis in pediatric leukemia patients using a common complete blood count test. The study found that combining the minimal residual disease indicator and absolute lymphocyte count provides better results than MRD alone, identifyin...
A recent international study on osteoporosis in women has found that most postmenopausal women are not aware of their actual risk of debilitating bone breaks. The study, which involved over 60,000 women aged 55 and older in 10 countries, highlights the need for public education about osteoporosis risk factors and treatment.
A study found that nearly one in ten primary care physicians experience conflicts with religious hospitals, with younger and less religious physicians more likely to face these issues. Most physicians feel they should refer patients to another institution if clinical judgment conflicts with hospital policy.
A study published in BMC Biology found that male fallow deer vocalizations contain accurate information about their competitive abilities, which change dynamically with age. The researchers also discovered that the deer's vocal identity changes substantially from one year to the next.
The discovery of Australopithecus sediba, a 1.9 million-year-old human ancestor, has shed new light on human evolution. The fossilized remains, found in South Africa, exhibit features of both earlier bipedal apes and more recent Homo species.
Researchers developed a new endoscopic technique, the over-the-scope-clip (OTSC), to close chronic gastrointestinal perforations. The study successfully closed two gastro-cutaneous fistulas and suggests OTSC as a least invasive method for closing small fistulas or leaks.
A new initiative called Cell-All aims to equip cell phones with sensors capable of detecting deadly chemicals. The technology uses a chip costing less than a dollar and can alert the user and authorities in under 60 seconds, reducing false positives and improving response time.
Research published in World Journal of Gastroenterology found that fermented milk with Streptococcus thermophilus CRL 1190 exhibited therapeutic effects on chronic gastritis, particularly by modulating the immune response and increasing the thickness of the gastric mucus gel layer. This natural alternative may offer a potential treatme...
A new study found that stress can aggravate the impact of prior streptococcal infection on symptoms of Tourette syndrome and obsessive-compulsive disorder. The researchers identified a link between psychosocial stress and worsening tic and obsessive-compulsive symptom severity in children with Tourette syndrome and OCD.
A team of researchers from the University of Arizona revisited evidence pointing to a cataclysmic event that wiped out North American megafauna, including mammoths and Dire wolves. The study found no conclusive link between an extraterrestrial impact and the extinction of these species.
A new Europe-wide strategy for preventing type 2 diabetes has been developed, recommending lifestyle changes such as weight loss and increased physical activity to prevent the disease. The guidelines aim to halve the incidence of type 2 diabetes by implementing evidence-based prevention programs across European countries.
A study published in World Journal of Gastroenterology reports successful endoscopic resection of a large ileal lipoma using the modified endoscopic submucosal dissection (ESD) technique. The procedure, combined with endoscopic unroofing, allowed for complete removal of the lesion without complications.
A study comparing preoperative and postoperative chemoradiotherapy to surgery alone in patients with resectable esophageal squamous cell carcinoma found significant differences in overall survival and progression-free survival. Perioperative chemoradiotherapy maximizes long-term survival, but increases toxicity.
Scientists argue that a 'Global Fund for Health' would improve transparency and efficiency in international health aid. The current system masks variances, making it difficult to accurately trace health funding.
DISH is a common but often unrecognized systemic disorder that can lead to mechanical esophageal dysphagia in older adults. A recent study concludes that DISH should be considered an important cause of dysphagia among older adults, although it should not be accepted as the sole cause without ruling out other possible causes.
Research found a significant association between high LRP16 expression and early disease progression or death in patients with colorectal cancer. The study suggests that LRP16 expression may serve as a molecular marker for predicting prognosis.
The 'crowding out' effect occurs when governments use health aid to partly replace domestic health budgets, rather than supplement them. Possible reasons include reallocating funding to different sectors, stalling increases in recurrent health expenditure, or spreading spending over several years.
The Southwest Oncology Group's operating grants have been renewed for six years, with a total expected to exceed $120 million over the period. The renewal supports comparative effectiveness research and will primarily fund member institutions nationwide.
Scientists have uncovered key rules governing ferritin's self-assembling nanostructure, enabling potential breakthroughs in drug development and nanotechnology. The study may lead to creating biological nanostructures with precise dimensions for various applications.
ARS scientists have developed a method to access and ferment almost all plant sugars in wheat straw, boosting ethanol output by 93 gallons per ton. However, they also found that certain bacteria can infect ethanol plants, causing yield decreases of up to 27%.
