AI can predict the effectiveness of breast cancer chemotherapy

Engineers at the University of Waterloo have developed artificial intelligence (AI) technology to predict if women with breast cancer would benefit from chemotherapy prior to surgery. The new AI algorithm, part of the open-source Cancer-Net initiative led by Dr. Alexander Wong, could help unsuitable candidates avoid the serious side effects of chemotherapy and pave the …

New drug molecules could prevent skin aging caused by sun exposure

Two new molecules that generate minute amounts of the gas hydrogen sulfide have been found to prevent skin from ageing after being exposed to ultraviolet light found in sunlight. Sunburn is a major cause of premature ageing in skin, and a primary risk factor for skin cancer, and other skin problems associated with ageing. Now, …

Developing therapies for treatment-resistant prostate cancer

Investigators from Cedars-Sinai Cancer have identified an investigational therapeutic approach that could be effective against treatment-resistant prostate cancer. Results of their Phase II clinical trial, published in the peer-reviewed journal Molecular Therapy, have led to a larger, multicenter trial that will soon be underway. Cancer of the prostate, a small gland just below the bladder, …

Does lifetime exposure to estrogen affect risk of stroke?

People with a higher cumulative estrogen exposure throughout their life may have a lower risk of stroke, according to a new study published in the February 1, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The lower risk was found for both ischemic stroke and intracerebral hemorrhage. An ischemic …

Study shows FDA-approved TB regimen may not work against the deadliest form of TB due to multidrug-resistant strains

Findings from a Johns Hopkins Children’s Center study in animal models show that a U.S. Food and Drug Administration (FDA)-approved antibiotic regimen for multidrug-resistant (MDR) tuberculosis (TB) may not work for TB meningitis. Studies in a small number of people also provide evidence that a new combination of drugs is needed to develop effective treatments …

Can we go from scarface to scarless?

Although human skin heals from injuries and wounds, many of us have scars that are left behind. Scar formation happens in adult mammals because skin regeneration does not fully occur. This poses a challenge to physicians who wish to conduct surgeries without scars appearing afterwards. In a newly published article in Biomedicines, a team led …

Neuronal molecule makes prostate cancer more aggressive

Prostate cancer is the second most common cancer and the second leading cause of cancer death among American men. Now, researchers have discovered key molecular players that drive prostate cancer to progress into a highly aggressive form of the disease called neuroendocrine prostate cancer that currently has no effective treatment. The finding uncovers new avenues …

More steps, moderate physical activity cuts dementia, cognitive impairment risk

Senior women were less likely to develop mild cognitive impairment or dementia if they did more daily walking and moderate-to-vigorous physical activity, according to a new study led by the Herbert Wertheim School of Public Health and Human Longevity Science at University of California San Diego. In the Jan. 25, 2023 online edition of Alzheimer’s …

Machine learning model builds on imaging methods to better detect ovarian lesions

Although ovarian cancer is the deadliest type of cancer for women, only about 20% of cases are found at an early stage, as there are no real screening tests for them and few symptoms to prompt them. Additionally, ovarian lesions are difficult to diagnose accurately — so difficult, in fact that there is no sign …
