Boston – Four teams of Dana-Farber Cancer Institute investigators have found that people experience discrimination and bias in different ways and in more realms of cancer care than previously understood. The findings, in different studies, suggest that oncology professionals and the systems they work in have more work to do to adapt to the realities of increasing diversity and inclusion, not only in the patient population but also in the oncology workforce. The research teams will present their findings at the 2024 Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago. ASCO is the world’s largest clinical cancer ...

ROCHESTER, Minnesota — Early detection improves treatment outcomes for endometrial and ovarian cancers, yet far too often women are diagnosed in advanced stages of these diseases. Unlike many other cancers, there are no standard screenings for early detection of endometrial and ovarian cancers. The incidence rate for endometrial cancer is expected to rise, driven by environmental factors, obesity and diabetes. Marina Walther-Antonio, Ph.D., and colleagues at Mayo Clinic's Center for Individualized Medicine are on a mission to catch these cancers early. Their research dives deep into the microbiome, a community of ...

BIRMINGHAM, Ala. – RNA transcription is the genomic process in which a cell produces a duplicate of a gene’s DNA sequence. In a study published in Nucleic Acids Research, University of Alabama at Birmingham Department of Chemistry Professor Jun Zhang, Ph.D., and his team reveal how the protein SRSF1 possesses the novel function of binding and unfolding complex RNA Guanine-quadruplexes.

Osteoporosis, a condition characterized by porous and fragile bones, poses a significant threat to skeletal health. As the very framework of the human body, bones provide crucial structural support. When bone mass diminishes, it not only compromises this support but also impairs overall function, leading to a diminished quality of life. With the aging population experiencing a surge in osteoporosis cases, the strain on healthcare resources for long-term care is evident. Hence, there is a need to understand the mechanisms that contribute to osteoporosis and develop effective targeted therapies ...

Transgender individuals often face unique challenges in aligning their physical bodies with their true gender identity. Among the various methods employed, gender-affirming hormone therapy (GAHT) stands as a vital means for transgender men to achieve physical changes in consonance with their gender identity. Navigating the complexities that come with gender transition, transgender individuals seek medical interventions to alleviate gender dysphoria and align their bodies with their gender identity. For transgender men, testosterone therapy holds promise in inducing masculinizing effects such as increased muscle mass, cessation of ...

Recommendations designed to reframe the evaluation of in vitro diagnostic tests have been published today by the Royal Statistical Society in its Series A journal.   The report, which will be submitted to the UK Covid-19 Inquiry, is intended to help prevent future scenarios in which IVDs are marketed widely, but later attract serious concerns about the standards applied to their evaluation.   The research was prompted by concerns about the standards applied to the evaluation of diagnostic tests during the Covid-19 pandemic – particularly lateral flow tests – however the recommendations cover all new tests, especially those ...

The process of aging is accompanied by a decline in physiological functions, which can lead to cardiovascular, neurodegenerative, and metabolic diseases. Aging of cells, also known as ‘cellular senescence’— is a process in which a cell ages and permanently stops dividing but does not die. The accumulation of such ‘senescent’ cells in tissues is then known to contribute to age-associated diseases. Elimination of senescent cells or ‘senolysis’ can, therefore, serve as an effective therapeutic strategy for the improvement of physiological function and prevention ...

New findings on long COVID — long-term effects on health experienced by many who have had COVID-19 — present a good-news, bad-news situation, according to a study at Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care system. The bad news: COVID-19 patients who were hospitalized within the first 30 days after infection face a 29% higher risk of death in the third year compared with people who have not had the virus. However, the three-year death risk still marks a significant decline compared with such risk at the one- and two-year marks post-infection. The findings also show that even people with mild COVID-19 were still ...

Osaka, Japan – The compound of iron and aluminum with the chemical formula Fe3Al has some very useful mechanical properties.

STARKVILLE, Miss.— A Mississippi State faculty member’s work on symbiosis—a mutually beneficial relationship between living organisms—is pushing back against the newer theory of a “single-origin” of root nodule symbiosis (RNS)—that all symbiosis between plant root nodules and nitrogen-fixing bacteria stems from one point—instead suggesting a “multiple-origin” theory of symbiosis which opens a better understanding for genetically engineering crops. Ryan A. Folk, an assistant professor in the MSU Department of Biological Sciences and herbarium curator, is an author on a paper published this month in Nature ...

Shortly after artificial intelligence models including Midjourney and OpenAI’s Dall-E went public, AI-generated art started winning competitions: one in digital art, another in photography. Concern rumbled that AI could replace artists — and even, by some metrics, be more creative than humans. But simultaneously, people were exploring these tools as ways to augment their creative processes, not replace them. University of Washington researchers grew curious about how AI might affect creativity in children, specifically, so they worked with a group of 12 Seattle-area kids ages seven to 13 to explore how the kids’ creative processes interacted ...
