Radiologic Insights: Diagnosing Lumbosacral Transitional Vertebrae. Systematic Review of the Literature

Pain Practice, Volume 26, Issue 3, March 2026.
ABSTRACT Introduction The lumbosacral transitional vertebra (LSTV) has been studied since 1876, with Castellvi developing a classification in 1984 based on its anatomy and laterality. It often goes unnoticed, or its diagnosis is limited to a lumbar spine X‐ray for confirmation. This has led to LSTV being underdiagnosed or even ignored.

Constitutive nitric oxide synthases deficiency impairs cyclobutane pyrimidine dimer repair following solar UV exposure in cells and mice

Photochemistry and Photobiology, Volume 102, Issue 2, Page 315-327, March/April 2026.
Proposed model for the dual role of cNOS in DNA damage and repair upon UV radiation. Abstract Solar ultraviolet (sUV) radiation is a major environmental factor that induces DNA damage, promoting skin aging and carcinogenesis. The formation of cyclobutane pyrimidine dimers (CPDs) is one of the most prevalent forms of UV‐induced DNA lesions, playing a ...

The tasiR‐ARF pathway in plants: origin, functions, and interplay of miR‐390, tasiRNAs and ARF3

Plant Biology, Volume 28, Issue 2, Page 328-344, March 2026.
Trans‐acting small interfering RNAs that silence a subset of Auxin Response Factors are crucial for plant growth, developmental timing, proper organ patterning, and coping with stress. Abstract Trans‐acting small interfering RNA (tasiRNAs) are a special type of endogenous small RNAs (sRNAs) found only in plants.
