A growing body of evidence suggest that the stem cell antigen-1 expressing (Sca-1) cells in the heart may be the cardiac endothelial stem/progenitor cells. Their endothelial cell (EC) functions, and their role in RV physiology and pathophysiology of right heart failure (RHF) remains poorly defined. This study investigated EC characteristics of rat cardiac Sca-1 cells, assessed spatial distribution and studied changes in Sca1 cells during RV remodelling in monocrotaline (MCT) model of pulmonary hypertension and RV remodeling.

- Transition metal dichalcogenides (TMDs) can exist in two phases: the stable 2H phase and the metastable 1T phase, and manipulating these phases is key for improving their use in optoelectronic devices.
- This study successfully synthesizes large-area monolayered 2H-MoS and mixed-phase 1T/2H-MoS using a catalyst-free chemical vapor deposition method by controlling the growth temperature.
- The mixed-phase devices demonstrate significantly improved performance, with a 55-fold increase in responsivity and a 10-fold increase in detectivity compared to pure 2H-MoS, due to self-doping effects from the metallic 1T phase boosting carrier
Article Synopsis
- The prevalence of opiate use is rising, affecting about 0.6% of the global population, leading to many infants being born with prenatal opioid exposure.
- Animal and human studies show that this exposure negatively impacts brain development and anatomy, but the effects of postnatal exposure on hospitalized infants are less understood.
- The review discusses the effects of both prenatal and postnatal opioid exposure on neurodevelopment and suggests resources and strategies to address and possibly reduce developmental setbacks in affected infants.
It is unclear if SARS CoV-2 infection during pregnancy is associated with adverse neurodevelopmental repercussions to infants. We assessed pediatric neurodevelopmental outcomes in children born to mothers with laboratory-confirmed SARS CoV-2 infection during pregnancy. Neurodevelopmental outcomes of in-utero exposed children were compared to that of pre-pandemic control children in Los Angeles (LA), CA, USA and Rio de Janeiro, Brazil.
