A team of scientists has made a breakthrough discovery in understanding how the HIV virus attaches to immune system cells, revealing new targets for anti-HIV vaccines and drugs. The study found that the virus uses multiple defenses to evade attack, including shape-shifting projections and carbohydrate molecules.
A protein called osteogenic protein-1 (OP-1) may speed the recovery of stroke patients by rewiring damaged brain cells. The experiment used rats and showed that OP-1 helped them recover lost movement in their limbs quickly, outperforming those in a control group.
A new study found that daily pain among elderly nursing home residents with cancer is widespread and often untreated, especially among older and minority patients. The study highlights inadequate medical treatment and a need for improving pain management in these individuals.
A new study reveals a link between excess thiamine and tumor-cell growth, suggesting that too much of the vitamin can actually help tumors grow. The researchers propose rational use of dietary thiamine may slow tumor growth.
Researchers have discovered a possible atomic process behind sonoluminescence, which could aid in the emerging field of sonochemistry. The study proposes that stimulated atoms decaying in unison emit light, explaining the short pulses observed in sonoluminescence.
Researchers are exploring ways to control the rush of nitrogen and other chemicals into the Mississippi River watershed. Ecotechnology may hold the answer by restoring or building wetlands and riparian buffer zones along waterways.
The new guidelines provide a comprehensive framework for healthcare professionals to diagnose and treat overweight and obesity in adults. Key findings include the importance of assessing body mass index (BMI), waist circumference, and risk factors for diseases associated with obesity, as well as recommending calorie reduction, increase...
The crystal structure of gp120 in action provides valuable clues for vaccine design, revealing how the virus binds to T cells while maintaining changeability. Researchers can now use this information to create targeted compounds that interfere with the interaction between gp120 and CD4 receptors.
A new study found that stress can lengthen the time dental wounds take to heal by 40% and reduce interleukin-1 production, a crucial cytokine for wound healing. Researchers believe that early supportive therapies may counteract this slowing effect, which occurs in the first few days after injury.
Scientists have found that parts of the protein shell of the common cold virus flap open in a motion called "breathing", which can be stifled by compounds that stop viruses from infecting cells. This discovery could lead to rapid screening methods for antiviral drugs.
Researchers at Ohio State University warn golfers with knee injuries that playing too soon can cause further damage to an injured knee. The study found that a full golf swing places significant stress on knee joints, regardless of shoe type or skill level.
