Lack of TRIC-B dysregulates cytoskeleton assembly, trapping β-catenin at osteoblast adhesion sites.

The trimeric intracellular cation channel B (TRIC-B), encoded by TMEM38B, is a potassium (K) channel present in the endoplasmic reticulum membrane, where it counterbalances calcium (Ca) exit. Lack of TRIC-B activity causes a recessive form of the skeletal disease osteogenesis imperfecta (OI), namely OI type XIV, characterized by impaired intracellular Ca flux and defects in osteoblast (OB) differentiation and activity. Taking advantage of the OB-specific Tmem38b knockout mouse (Runx2Cre;Tmem38b; cKO), we investigated how the ion imbalance affects the osteogenetic process.

Valve-sparing versus bio-Bentall aortic root replacement in patients aged 60-75 years: Survival, Reintervention and Aortic Regurgitation.

Background: Valve-sparing root replacement(VSRR) with the David technique is an established therapy for aortic root pathology in young patients. The aim of this study was to evaluate short and long-term outcomes between VSRR and aortic root replacement(ARR) with a biological-valved conduit in sexagenarians.

Methods: A multicenter retrospective review from 2002-2022 identified 299-sexagenarians undergoing aortic root surgery, among whom 82(27.

Extracellular Vesicle miR-122-5p as a Prognostic Biomarker in Pediatric Classical Hodgkin Lymphoma.

Currently, risk stratification for pediatric Hodgkin lymphoma is based on clinical factors such as stage, bulk, and systemic symptoms. Novel minimally invasive biomarkers could enhance both prognosis and treatment strategies. Therefore, the plasma extracellular vesicles' microRNA profile was characterized by small RNA sequencing in 36 classical Hodgkin lymphoma cases and these findings were confirmed in an extended cohort of 86 patients by RT-qPCR.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Tree drought physiology: critical research questions and strategies for mitigating climate change effects on forests.

Droughts of increasing severity and frequency are a primary cause of forest mortality associated with climate change. Yet, fundamental knowledge gaps regarding the complex physiology of trees limit the development of more effective management strategies to mitigate drought effects on forests. Here, we highlight some of the basic research needed to better understand tree drought physiology and how new technologies and interdisciplinary approaches can be used to address them.
