A new study reveals that an investigational drug, R207910, is effective in killing latent tuberculosis bacteria. The drug targets a protein essential for energy production in active TB, suggesting a potential Achilles heel for dormant bacteria.
Scientists at the University of Granada have developed a new condensed TLM node to model meta-materials, allowing for the creation of structures that can hide objects in conditions difficultly reachable with commercial software. This breakthrough uses a combination of electromagnetic parameters and judicious frame design to improve hid...
Researchers have found that more than half of a proton's spin comes from the orbital motion of its quarks, rather than their spinning. This new theory resolves a long-standing puzzle in physics and agrees with recent experiments and supercomputer calculations.
A new back lift procedure has been introduced by the American Society of Plastic Surgeons, removing unsightly back fat rolls and bulges while hiding the scar under the bra line. The study found minimal complications and positive feedback from patients who underwent the procedure.
A new study published in the New England Journal of Medicine found that physical therapy combined with medical management is just as effective as arthroscopic knee surgery in relieving pain and stiffness. Physical therapists can design personalized exercise programs to improve motion, strength, and conditioning.
Researchers have identified a coral gene called STPCA that responds to light cycles and produces bicarbonate to buffer against acidity. This adaptation allows corals to survive in shallow waters with limited food resources.
Researchers found that reducing coal emissions can keep atmospheric carbon dioxide levels below harmful levels if phased out within the next few decades. The study suggests that oil and gas should be used sparingly as well, but coal must be the main target of reductions.
A team of researchers has developed a method to separate parasitic organisms from their host cells using fluorescent proteins, allowing for more detailed studies. The approach yielded the identification of 509 proteins in the parasites, providing valuable characteristics such as fatty acid degrading enzymes.
The Association of Specialty Professors (ASP) has announced the seventh class of T. Franklin Williams Scholars, who will research and develop career plans focused on integrating geriatrics into internal medicine specialties. The 12 new scholars will join the previous 52 recipients to achieve the program's goal.
Dialysis patients with depression are nearly twice as likely to be hospitalized or die within a year compared to those without depression. The study found that more than 80% of depressed patients died or were hospitalized, while only 43% of non-depressed patients experienced these outcomes.
A new type of drug targets CB2 receptors to alleviate pain in human sensory nerves without affecting the brain. This research offers a promising alternative to opioids, which can have serious side effects such as dependency and nausea.
A study by Henry Ford Health found that 90% of patients who underwent cardiac nuclear stress testing did so appropriately under updated guidelines. However, 21 patients received unnecessary tests, highlighting the potential for savings through adherence to test-appropriateness criteria.
Research suggests that eating broccoli may help patients with chronic lung disease by reducing oxidative stress and inflammation. The study found decreased levels of NRF2-dependent antioxidants and increased oxidative stress markers in lungs of smokers with COPD.
A new technique using flexible gastrointestinal endoscope with miniature ultrasound transducer can directly inject cancer fighting agents into tumors, avoiding normal tissue damage. This approach, combined with systemic chemotherapy, shows promise in treating certain cancers.
A study by Johns Hopkins researchers found that NRF2, a master gene regulating antioxidant and pollutant-detoxifying genes, is significantly decreased in smokers with advanced COPD compared to those without. This discovery could lead to new drug therapies targeting the condition.
Research suggests that sleep apnea can lead to erectile dysfunction due to chronic intermittent hypoxia. However, treatment with tadalafil can reverse the effects and improve sexual function in mice exposed to CIH for extended periods. Further studies are needed to explore alternative interventions.
Scientists have discovered a new mineral, xieite, with a post-spinel structure in the Suizhou meteorite. The mineral is a high-pressure polymorph of chromite-spinel with a density about 10% denser than chromite.
