Background/objectives: Neurodegenerative ocular diseases, such as age-related macular degeneration (AMD) and glaucoma, represent growing public health concerns. Oxidative stress plays a key role in their development, damaging retinal cells and accelerating disease progression. Melatonin (Mel) is a potent antioxidant with neuroprotective properties; however, it faces limitations such as low solubility.

, a recently described endemic species from southern Peru, belongs to the Amaryllidaceae family and is known for its diversity of alkaloids. Amaryllidoideae have been studied for their diverse biological activities, particularly for their properties in treating neurodegenerative diseases. This work examines the alkaloidal profile using GC-MS and UPLC-MS/MS of alkaloid-enriched extracts obtained from the leaves and bulbs of and their inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes.

Herein, we report the presence of a plant paleocommunity, dominated by ferns of the family Osmundaceae, structurally preserved from the only known Mesozoic, fossiliferous geothermal deposits, from the La Matilde Formation (Middle-Upper Jurassic) in the Deseado Massif of Southern Patagonia, Argentina. A total of 13 siliceous chert blocks sampled in an area of approximately 250 m, preserving a monotypic assemblage dominated by Osmundaceae embedded within its original swampy substrate, are documented. Additional Osmundaceae and fewer ferns and conifers are present in the stratigraphically continuous, adjacent chert levels.

: For many years, advancements in hand joint replacement (JR) were relatively minor compared to those for large joints. However, the caution previously exercised due to high complication rates is gradually being replaced by the expanding use of JR therapies for small joints in the hand. Despite this progress, there is a lack of comprehensive data on the outcomes of hand JR and on the optimal infrastructure required to meet the growing demand for these therapies.

Background: Dupuytren's disease (DD) is a systemic connective tissue disorder of the palm, predominantly affecting men of Northern European or Caucasian origin over 55. In addition to conventional surgery, Dupuytren's contracture can be treated in a minimally invasive way by injecting bacterial collagenase into the cord. However, studies on the long-term success rate when compared to the gold standard, surgical limited fasciectomy, are limited.
