Major ‘third-hand smoke’ compound causes DNA damage and potentially cancer

Major ‘third-hand smoke’ compound causes DNA damage and potentially cancer

Leftover cigarette smoke that clings to walls and furniture is a smelly nuisance, but now research suggests that it could pose a far more serious threat, especially to young children who put toys and other smoke-affected items into their mouths. Scientists reported today that one compound from this “third-hand smoke,” which forms when second-hand smoke reacts with indoor air, damages DNA and sticks to it in a way that could potentially cause cancer Continue reading

Small-RNA pathway defends genome against enemy within

Small-RNA pathway defends genome against enemy within

Reproductive cells, such as an egg and sperm, join to form stem cells that can mature into any tissue type. But how do reproductive cells arise? We humans are born with all of the reproductive cells that we will ever produce Continue reading

Advance toward developing an oral pain reliever derived from debilitating snail venom

Advance toward developing an oral pain reliever derived from debilitating snail venom

Scientists have reported they have created at least five new experimental substances — based on a tiny protein found in cone snail venom — that could someday lead to the development of safe and effective oral medications for treatment of chronic nerve pain. They say the substances could potentially be stronger than morphine, with fewer side effects and lower risk of abuse. “This is an important incremental step that could serve as the blueprint for the development of a whole new class of drugs capable of relieving one of the most severe forms of chronic pain that is currently very difficult to treat,” said David Craik, Ph.D., who led the study Continue reading

New nanoparticle that only attacks cervical cancer cells

New nanoparticle that only attacks cervical cancer cells

One of the most promising technologies for the treatment of various cancers is nanotechnology, creating drugs that directly attack the cancer cells without damaging other tissues’ development. The Laboratory of Cellular Oncology at the Research Unit in Cell Differentiation and Cancer, of the Faculty of Higher Studies (FES) Zaragoza UNAM (National Autonomous University of Mexico) developed a therapy to attack cervical cancer tumors.

New approach to chronic lymphocytic leukemia treatment

New approach to chronic lymphocytic leukemia treatment

Dartmouth researchers have developed a novel and unique approach to treating Chronic Lymphocytic Leukemia (CLL), a form of blood cancer that often requires repeated chemotherapy treatments to which it grows resistant. The researchers, led by Alexey V Continue reading
