Trends in surgical procedures for shoulder instability among patients with Ehlers-Danlos syndrome or joint hypermobility syndrome.

Background: Joint hypermobility syndrome (JHS) and Ehlers-Danlos Syndrome (EDS) are connective tissue disorders characterized by increased joint laxity, affecting musculoskeletal health and quality of life. In this study, we explored recent trends in surgical treatment of shoulder instability among patients with these disorders.

Methods: We searched the PearlDiver Mariner database, which includes deidentified US all-payer claims data from 2010 to 2020.

DPP4, a potential tumor biomarker, and tumor therapeutic target: review.

Dipeptidyl peptidase 4 (DPP4) is a serine protease widely distributed in membrane-bound and soluble forms in various tissues and organs throughout the body. DPP4 plays a role in inflammation, immune regulation, cell growth, migration and differentiation. The role of DPP4 in tumors has garnered increasing attention.

Maternal ELL3 loss-of-function leads to oocyte aneuploidy and early miscarriage.

Up to an estimated 10% of women experience miscarriage in their lifetimes. Embryonic aneuploidy is a leading cause for miscarriage, infertility and congenital defects. Here we identify variants of ELL3, a gene encoding a transcription elongation factor, in couples who experienced consecutive early miscarriages due to embryonic aneuploidy.

Motion-Onset Visually Evoked Potentials (VEPs) are Amplified in The Deaf.

The loss of a sensory modality triggers a phenomenon known as cross-modal plasticity, where areas of the brain responsible for the lost sensory modality are reorganized and repurposed to the benefit of the remaining modalities. After perinatal or congenital deafness, superior visual motion detection abilities have been psychophysically identified in both humans and cats, and this advantage has been causally demonstrated to be mediated by reorganized auditory cortex. In our study, we investigated visually evoked potentials (VEPs) in response to motion-onset stimuli of varying speeds in both hearing and perinatally deafened cats under light anesthesia.

Palladium-Catalyzed Tandem Reactions via Allene Intermediates for the Rapid Synthesis of a Fused Indenone-Indole Scaffold.

A palladium-catalyzed tandem reaction of 1-(2-iodophenyl)-3-arylprop-2-yn-1-ones and 1-(2-azidophenyl)propargyl ethers is developed to provide the rapid construction of a fused polycyclic indenone-indole scaffold under mild conditions. The reaction proceeds via a highly ordered process involving Sonogashira coupling, propargyl-allenyl isomerization, allene-azide cycloaddition, denitrogenation, and diradical coupling. The proposed reaction mechanism is supported by experimental and computational studies.
