Trial shows chemotherapy is helping kids live with pulmonary vein stenosis

A clinical trial conducted by Boston Children's Hospital has shown that adding chemotherapy to a treatment regimen including catheterization and surgery can deter abnormal cellular growth in children with pulmonary vein stenosis. The approach led to the stabilization of PVS progression and prevention of further lung damage in 31% of pa...

Opening a new door to immunity

Researchers uncover clue to disease process development by identifying novel way to control innate immune response, which may translate to treatments for conditions such as atherosclerosis, autoimmunity, and heart failure. Animal studies support finding, showing mice with mutated sNASP proteins are more susceptible to septic infection.

Is colonialism creating inappropriate regulation of traditional medicine practitioners?

Two commentaries in JACM question whether colonial models devalue traditional and complementary practices. Researchers Heather Boon and Nadine Ijaz argue that biomedical dominance subordinates indigenous knowledge systems, while Editor-in-Chief John Weeks emphasizes the need for re-examining harmful limits of biomedicine's approach.

Alignment of mother and offspring body clock could prevent diseases such as heart disease and obesity

A new study published in The Journal of Physiology found that proper maternal care can significantly reduce abnormalities in the offspring's body clock, leading to a lower likelihood of developing heart disease. This suggests that early life experiences may play a crucial role in shaping an individual's health later in adulthood.

Clouds like a semi-transparent parasol

Dr. Anna Possner will join the Goethe University in Frankfurt to investigate the impact of low-level clouds on Earth's surface temperature. Her research focuses on semi-transparent parasols that reflect sunlight but have a minimal effect on heat emission, and she aims to improve understanding of their influence.

Isotopic evidence for enhanced fossil fuel sources of aerosol ammonium in the urban atmosphere

A new chemical method is used to determine nitrogen stable isotope composition at natural abundance for ammonium, revealing source dependence of isotopic abundance in urban Beijing. Fossil fuel emissions are found to be a significant source of aerosol ammonium, accounting for 37-52% of initial ammonia concentrations.

Genetic analysis for certain childhood brain tumors soon a standard-of-care?

Researchers have developed criteria for routine genetic screening of patients with medulloblastoma, a rare and malignant tumor predominantly affecting children. This analysis of 1022 patients identified six genes frequently affected by genetic alterations, increasing cancer risk in up to 20% of the patient population.

Beyond killing tuberculosis

Researchers at McGill University Health Centre discovered that having excessive T cells can cause harm and imbalance disease tolerance, leading to tissue damage. The study found that a protein called cyclophilin D acts as a key checkpoint for T cell activation, controlling the body's ability to tolerate Mtb infection.

Tiny spiders, big color

A team of Harvard scientists discovered that tiny Phoroncidia rubroargentea spiders use a combination of structural colors, pigment, and fluorescent material to produce their distinctive red and silver hues. The colors are stabilized by a tough cuticle layer, with the silver color relying on a reflective material similar to fish scales.
