(Press-News.org) About The Study: In contrast to earlier studies, this meta-analysis found significantly higher treatment failure and major complication rates within a year with nonoperative management among children and adolescents. The meta-analysis provides pediatricians and pediatric surgeons with up-to-date data to inform shared decision-making with families and encourage individualized, patient-centered treatment.

Metabolically active visceral fat linked to aggressive endometrial cancer, new study reveals
2025-10-04
(Barcelona, Spain, Sunday 5 October 2025) High metabolic activity of visceral fat may be associated with more aggressive endometrial cancer, new research presented today at the 38th Annual Congress of the European Association of Nuclear Medicine (EANM'25) has shown.1
While obesity is a recognised risk factor for endometrial cancer,2-3 the findings indicate that disease aggressiveness may be driven not only by the amount of visceral fat but also by its metabolic activity. Visceral fat is the fat that surrounds the internal organs, and to a larger degree than subcutaneous ...
Scientists glimpse how enzymes “dance” while they work, and why that’s important
2025-10-04
Tokyo, Japan – Researchers from Tokyo Metropolitan University have developed a new structure determination method using Nuclear Magnetic Resonance (NMR) spectroscopy which shows how different parts of complex molecular machinery like enzymes move while they help catalyze reactions. Focusing on an enzyme in yeast, they demonstrated how contrasts in atomic scale motions impact their function. The method promises unprecedented access to the mechanisms by which biomolecules work, and how they relate to illnesses.
Enzymes are indispensable to the function of all biological organisms, ...
California partnership aided COVID-19 response and health equity, report finds
2025-10-03
RIVERSIDE, Calif. -- The COVID-19 pandemic did not affect everyone equally. Communities of color, especially Latino (including undocumented persons), Black, and Native American groups, as well as people with low incomes, experienced much higher rates of infection, hospitalization, and death.
Research has shown that several key factors worsened health inequalities during the COVID-19 pandemic. Crowded housing, dense neighborhoods, and location played a major role in how the virus spread. Systemic racism, discrimination, and unstable jobs made some communities even more at risk.
A new report, published in Health Expectations, highlights how ...
University of Oklahoma secures $19.9 million for revolutionary radar technology
2025-10-03
NORMAN, Okla. – Researchers at the University of Oklahoma’s Advanced Radar Research Center (ARRC) continue to lead the way in radar innovation. A $19.9 million award from the U.S. National Science Foundation’s Mid-scale Research Infrastructure-1 program will fund the development of two groundbreaking KaRVIR systems (Dual-Doppler 3D Mobile Ka-band Rapid-Scanning Volume Imaging Radars for Earth System Science). These state-of-the-art radars will provide unique capabilities to close critical observational gaps in the atmospheric ...
Study finds restoring order to dividing cancer cells may prevent metastasis
2025-10-03
Triple negative breast cancer (TNBC) is one of the most aggressive and hardest forms of breast cancer to treat, but a new study led by Weill Cornell Medicine suggests a surprising way to stop it from spreading. Researchers have discovered that an enzyme called EZH2 drives TNBC cells to divide abnormally, which enables them to relocate to distant organs. The preclinical study also found drugs that block EZH2 could restore order to dividing cells and thwart the spread of TNBC cells.
“Metastasis is the main reason patients with triple negative breast cancer face poor survival odds,” said senior author Dr. Vivek Mittal, Ford-Isom Research Professor of Cardiothoracic Surgery and ...
High-accuracy tumor detection with label-free microscopy and neural networks
2025-10-03
Pancreatic neuroendocrine neoplasms (PNENs) are a rare form of cancer that affects hormone-producing cells in the pancreas. Although uncommon, their incidence has been rising steadily over the past few decades. Treatment options include chemotherapy and targeted therapies, but surgery remains the only chance for a cure. However, surgical decisions often depend on pathology results that can take hours or even days, delaying treatment and increasing the risk of incomplete tumor removal.
Researchers at the University of Arizona have developed a new imaging method that could help surgeons identify cancerous tissue more quickly and accurately. The technique, called multiphoton microscopy ...
Wayne State research reveals fetuses exposed to Zika virus have long-term immune challenges
2025-10-03
DETROIT — A Wayne State University study published in the Oct. 3, 2025, issue of Nature Communications revealed that Zika virus exposure during pregnancy causes long-term, sex-specific changes to a baby’s immune system, particularly affecting the frontline immune cells that fight infection.
The study, “Prenatal exposure to Zika virus shapes offspring neutrophil function in a sex-specific manner,” was led by Dr. Jiahui Ding, assistant professor of obstetrics and gynecology in Wayne State’s School of Medicine.
“We discovered that when a pregnant mother is infected with Zika virus, the resulting inflammatory ...
Researchers deconstruct chikungunya outbreaks to improve prediction and vaccine development
2025-10-03
The symptoms come on quickly — acute fever, followed by debilitating joint pain that can last for months. Though rarely fatal, the chikungunya virus, a mosquito-borne illness, can be particularly severe for high-risk individuals, including newborns and older adults.
While the virus is common in tropical and subtropical regions, including Asia, Africa and South America, public health officials have been tracking reported infections in Europe and, in September, a confirmed case in Long Island, New York.
Outbreaks ...
Study finds one-year change on CT scans linked to future outcomes in fibrotic lung disease
2025-10-03
DENVER (Oct 1, 2025) Researchers at National Jewish Health have shown that subtle increases in lung scarring, detected by an artificial intelligence-based tool on CT scans taken one year apart, are associated with disease progression and survival in patients with fibrotic interstitial lung disease. The findings, recently published in the American Journal of Respiratory and Critical Care Medicine, suggest that computer-based image analysis may provide an earlier, more objective way to identify patients at highest risk for worsening disease.
“We ...
Discovery of a novel intracellular trafficking pathway in plant cells
2025-10-03
Just like in yeast and animal cells, vacuoles in plants are responsible for breaking down unwanted cellular components. At the same time, vacuoles in seeds also serve the opposite role -storing large amounts of proteins that provide energy during germination. These storage proteins, accumulated in the vacuoles of seeds such as beans and wheat, are not only vital for plant growth but also represent an important agricultural resource closely tied to our daily diet.
Until now, it was entirely unknown whether proteins could be transported from the vacuole to other organelles. In a study now published ...
