Photobiomodulation: shining a light on depression.

Depression is a prevalent public health issue, characterized by persistent low mood, impaired concentration, and diminished motivation. Photobiomodulation (PBM), which involves the application of red or near-infrared light, modulates physiological processes by enhancing cerebral blood flow, reducing inflammation, inhibiting apoptosis, and promoting neurogenesis. PBM can be administered transcranially or through systemic approaches, offering a potentially effective intervention for depression.

CT-Based Body Composition and Frailty as Predictors of Survival Among Older Adults With Gastrointestinal Malignancies.

Background: Older adults with cancer are at an increased risk of treatment related toxicities and early death. Routinely collected clinico-demographic characteristics inadequately explain this increased risk limiting accurate prognostication. Prior studies have suggested that altered body composition and frailty are independently associated with worse survival among older adults with cancer; however, their combined influence remains unclear.

Cellular senescence as a key contributor to secondary neurodegeneration in traumatic brain injury and stroke.

Traumatic brain injury (TBI) and stroke pose major health challenges, impacting millions of individuals globally. Once considered solely acute events, these neurological conditions are now recognized as enduring pathological processes with long-term consequences, including an increased susceptibility to neurodegeneration. However, effective strategies to counteract their devastating consequences are still lacking.

Neutralizing GDF-15 can overcome anti-PD-1 and anti-PD-L1 resistance in solid tumours.

Cancer immunotherapies with antibodies blocking immune checkpoint molecules are clinically active across multiple cancer entities and have markedly improved cancer treatment. Yet, response rates are still limited, and tumour progression commonly occurs. Soluble and cell-bound factors in the tumour microenvironment negatively affect cancer immunity.
