The benefits of physical activity for older adults

Physically active older adults experience reduced risks of early death, breast and prostate cancer, fractures, and dementia. Physical activity also promotes healthier ageing trajectories, better quality of life, and improved cognitive functioning.

Study provides new understanding of mitochondria genome with potential for new avenues of treatment for multiple cancers

Researchers at the University of Texas MD Anderson Cancer Center have made significant progress in understanding the mitochondrial genome and its role in cancer. The study found that hyper-mutated cases in kidney, colorectal, and thyroid cancers suggest oncogenic impact with signaling pathway activation.

Dementia may reduce likelihood of a 'good death' for patients with cancer

A recent study published in Geriatrics & Gerontology International found that cancer patients with dementia were less likely to achieve a good death compared to those without. The study's authors emphasize the importance of enhancing end-of-life care discussions and improving symptom management for these patients.

Parkinson's and the immune system

Researchers have identified a link between the nervous system and immune system in Parkinson's disease, finding that genes like Parkin and PACRG protect nerve cells from cell death. These proteins regulate a signalling pathway that also plays a role in innate immunity, which prevents bacterial infections.

CD19 CAR NK-cell therapy achieves 73% response rate in patients with leukemia and lymphoma

The CD19 CAR NK-cell therapy achieved a 73% response rate in patients with relapsed or refractory non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL), with no major toxicities reported. The treatment was administered in an outpatient setting, and responses were evident within one month following infusion.

The invisibility cloak of a fungus

A fungal pathogen, Cryptococcus neoformans, has been found to use an enzyme called chitosan deacetylase to alter its cell wall structure, making it invisible to the human immune system. Researchers have identified a new chitosan deacetylase that is crucial for the fungus's ability to evade detection.

Does tramadol increase hip fracture risk?

A UK patient database analysis found tramadol increases hip fracture risk by up to 1.5 new cases per 1000 person-years, compared to other pain medications. The study highlights the need for tramadol's fracture risk to be considered in clinical practice and treatment guidelines.

Tiny 'bridges' help particles stick together

A team of researchers at the University of Pennsylvania found that when particles are wet and dry, thin solid bridges formed between larger clumps increase aggregates' stability. The size of particles plays a crucial role in determining how strongly they stick together.

Building a better breast

Researchers at UT Southwestern Medical Center have developed a new method for mapping out blood vessels before surgery to minimize the risk of complications in single breast reconstruction. The team found that this approach reduced fat necrosis by 2.7% compared to traditional methods, resulting in improved outcomes and breast shapes.
