Physiological Insights Into the Role of Pericytes in Spinal Cord Injury.

Vascular regeneration plays a vital role in tissue repair yet is drastically impaired in those with a spinal cord injury (SCI). Pericytes are of great significance as they are entwined with vessel-specific endothelial cells and actively contribute to maintaining the spinal cord's vascular network. Within the neurovascular unit (NVU), subtypes of pericytes characterized by various markers such as PDGFR-β, Desmin, CD146, and NG-2 are involved in vascular regeneration in SCI repair.

Lemierre Syndrome With Streptococcus constellatus Bacteremia.

Lemierre syndrome is characterized by thrombophlebitis of the internal jugular vein (IJV) secondary to bacterial pharyngitis or tonsillitis. Though antibiotic use has made this a rarer syndrome, it can nevertheless manifest in patients presenting with pharyngitis. Herein, we describe a 20-year-old male patient with no relevant medical history presenting with signs concerning for pneumonia and was ultimately diagnosed with Lemierre syndrome with bacteremia.

Distinct effects of AMPAR subunit depletion on spatial memory.

Pharmacological studies established a role for AMPARs in the mammalian forebrain in spatial memory performance. Here we generated global GluA1/3 double knockout mice () and conditional knockouts lacking GluA1 and GluA3 AMPAR subunits specifically from principal cells across the forebrain (). In both models, loss of GluA1 and GluA3 resulted in reduced hippocampal GluA2 and increased levels of the NMDAR subunit GluN2A.

The mediating role of caregiver hope in relations among caregivers' coping and emotional socialization beliefs in pediatric oncology.

The purpose of this study is to identify links between caregiver hope, caregiver coping behaviors, and caregivers' coaching versus dismissing emotion socialization (ES) beliefs in a pediatric cancer sample. Self-report measures. Caregivers ( = 183, 80.

Association between troponin level and medium-term mortality in 20 000 hospital patients.

Introduction: Cardiac troponin (cTn) concentrations above the manufacturer recommended upper limit of normal (ULN) are frequently seen in hospital patients without a clinical presentation consistent with type 1 myocardial infarction, and the significance of this is uncertain. The aim of this study was to assess the relationship between medium-term mortality and cTn concentration in a large consecutive hospital population, regardless of whether there was a clinical indication for performing the test.

Method: This prospective observational study included 20 000 consecutive in-hospital and outpatient patients who had a blood test for any reason at a large teaching hospital, and in whom a hs-cTnI assay was measured, regardless of the original clinical indication.
