Published: July 2005

The structures of MornigaM and the MornigaM-mannose complex have been determined at 1.8 A and 2.0 A resolution, respectively. Both structures adopt the typical beta-prism motif found in other jacalin-related lectins and their tetrameric assembly closely resembles that of jacalin. The carbohydrate-binding cavity of MornigaM readily binds mannose. No major structural rearrangements can be observed in MornigaM upon binding of mannose. These results allow corroboration of the structure-function relationships within the small group of Moraceae lectins.

Accurate and rapid diagnosis of traumatic brain injury (TBI) is essential for high-quality medical services. Nonetheless, the current diagnostic platform still has challenges in rapidly and accurately analysing clinical samples. Here, we prepared a highly stable, repeatable and sensitive gold-plated silver core-shell nanowire (Ag@AuNWs) for surface-enhanced Raman spectroscopy (SERS) metabolic fingerprint diagnosis of TBI.

Sclerosis is a highly morbid manifestation of chronic GVHD (cGVHD), associated with distressing symptoms and significant long-term disability. A patient-reported outcome measure (PRO) for cGVHD-associated sclerosis is essential to advance therapeutic trials. We aimed to develop a PRO for adults with cGVHD-associated sclerosis and evaluate and refine its content validity.

Background: Artificial intelligence (AI) social chatbots represent a major advancement in merging technology with mental health, offering benefits through natural and emotional communication. Unlike task-oriented chatbots, social chatbots build relationships and provide social support, which can positively impact mental health outcomes like loneliness and social anxiety. However, the specific effects and mechanisms through which these chatbots influence mental health remain underexplored.

(-)-Cryptanoside A () was identified previously as a major cytotoxic component of the stems of collected in Laos, which mediates its activity by targeting Na/K-ATPase (NKA), with hydrogen bonds formed between its 11- and 4'-hydroxy groups and NKA being observed in its docking profile. In a continuing investigation, and its 17-epimer, (-)-17--cryptanoside A (), and the new (+)-2-hydroxyandrosta-4,6-diene-3-one-17-carboxylic acid () and the known (+)-2,21-dihydroxypregna-4,6-diene-3,20-dione or 2-hydroxy-6,7-didehydrocortexone () pregnane-type steroids were isolated from .

The relative reactivity and cis/trans selectivity of the intramolecular [3+2] cycloaddition (IM32CA) reactions of nitrile oxide (NO), azide (AZ), nitrile sulfide (NS) and nitrile ylide (NY), leading to functionalized heterocycles are studied within the Molecular Electron Density Theory. The kinetically controlled IM32CA reactions are predicted to be cis stereospecific, while the reaction feasibility follows the order NY > NS > NO > AZ with the respective activation Gibbs free energies of 13.7, 17.
