Unravelling the interplay between ER stress, UPR and the cGAS-STING pathway: Implications for osteoarthritis pathogenesis and treatment strategy.

Osteoarthritis (OA) is a debilitating chronic degenerative disease affecting the whole joint organ leading to pain and disability. Cellular stress and injuries trigger inflammation and the onset of pathophysiological changes ensue after irreparable damage and inability to resolve inflammation, impeding the completion of the healing process. Extracellular matrix (ECM) degradation leads to dysregulated joint tissue metabolism.

Lupus Erythematous Profundus: An Unusual Manifestation in the Otolaryngological Setting.

Lupus erythematous profoundus (LEP) is an uncommon manifestation of chronic lupus erythematous (CLE) involving inflammation of the subcutaneous fat and deep dermis. It is rarely seen in the otolaryngological practice. We describe a case of a 33-year-old female who presented with bilateral acute onset cheek swelling, which led to the unexpected diagnosis of LEP.

Itaconic Acid as a Comonomer in Betulin-Based Thermosets via Sequential and Bulk Preparation.

The inherent chemical functionalities of biobased monomers enable the production of renewably sourced polymers that further advance sustainable manufacturing. Itaconic acid (IA) is a nontoxic, commercially produced biobased monomer that can undergo both UV and thermal curing. Betulin is a biocompatible, structurally complex diol derived from birch tree bark that has been recently studied for materials with diverse applications.
