Control of striatal circuit development by the chromatin regulator .
Sci Adv

The pathophysiology of neurodevelopmental disorders involves vulnerable neural populations, including striatal circuitry, and convergent molecular nodes, including chromatin regulation and synapse function. Despite this, how epigenetic regulation regulates striatal development is understudied. Recurrent de novo mutations in are associated with intellectual disability and autism.

P2X receptors (P2XRs) are adenosine 5'-triphosphate (ATP)-gated ion channels comprising homomeric and heteromeric trimers of seven subtypes (P2X1-P2X7) that confer different rates of desensitization. The helical recoil model of P2XR desensitization proposes stability of the cytoplasmic cap sets the rate of desensitization, but timing of its formation is unclear for slow-desensitizing P2XRs. We report cryo-electron microscopy structures of full-length wild-type human P2X4 receptor in apo closed, antagonist-bound inhibited, and ATP-bound desensitized states.

Faculty of Dentistry, Department of Restorative Dentistry, Çanakkale Onsekiz Mart University, Çanakkale, 17100, Turkey.
Objectives: This study aimed to evaluate the effectiveness of home-use desensitizing agents over an 8-week period by comparing them using different measurement methods.
Methods: A randomized, controlled clinical trial was conducted with 180 individuals aged between 18 and 70 who clinically diagnosed dentin hypersensitivity (DH) in two or more non-adjacent teeth. Subjects who met the inclusion criteria (n = 164) were randomly allocated into five test groups-using Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), Arginine, Novamin, Propolis, and Potassium nitrate-and a control group using standard fluoride toothpaste.

Institute of Allergy, Immunology and Pediatric Pulmonology, Yitzhak Shamir Medical Center; Department of Pediatrics, Faculty of Medicine, Tel Aviv University.
Background: Data on oral immunotherapy (OIT) for hazelnut allergy is limited and its potential to cross-desensitize for other nuts is unknown.
Objective: To study the efficacy and safety of hazelnut OIT in desensitizing hazelnut and additional tree nuts.
Methods: A prospective observational study of 30 hazelnut allergic patients aged ≥4 years who underwent hazelnut OIT.
