Article Synopsis
  • Bone homeostasis involves EphB2 and EphB3 receptors in mesenchymal stromal/stem cell differentiation into bone tissue.
  • In vitro studies show that EphB3-/- MSCs express more osteogenic factors while EphB2-/- MSCs lean towards fat cell differentiation.
  • In vivo experiments with mouse models indicate that EphB3 deficiency protects against bone loss by maintaining higher levels of osteoprogenitor and preosteoblast cells, highlighting its role as a negative regulator of bone differentiation.

Background: The purpose of this study is to compare the incidence of complications associated with tension band wiring (TBW) versus plate osteosynthesis (POS) in the treatment of olecranon fractures.

Methods: We performed a retrospective cohort study of operatively treated adult olecranon fractures from an integrated healthcare system by multiple surgeons from January 2008 to December 2011. Patients were divided into two cohorts: fractures fixed using the tension band technique and fractures fixed using plate osteosynthesis.

Article Synopsis
  • Chagas disease during its acute phase causes high levels of parasite infection in the host's bloodstream and tissues, particularly affecting the bone marrow.
  • Infected mice show a decrease in certain cell types in the bone marrow, despite an increase in hematopoietic stem and progenitor cells at 14 days post-infection, indicating complex interactions during infection.
  • The study highlights that while some progenitor populations decline, there is a notable increase in hematopoietic stem and progenitor cells in both bone marrow and spleen, suggesting a response to the infection that may involve emergency hematopoiesis.

Coal combustion can release large amounts of polycyclic aromatic hydrocarbons (PAHs), which persist in various environment matrices (e.g., road dust) and hence cause the carcinogenic risk to human health.

Coal-fired power plants are important sources of polycyclic aromatic hydrocarbon (PAH) emissions in the world. The effects of various air pollution control devices (APCDs) on PAH emissions were investigated by analyzing samples from inlets and outlets of APCDs in six coal-fired power plants (A-F) and two coal-fired industrial boilers (G and H). The APCDs were electrostatic precipitators (ESPs), wet flue gas desulfurization systems (WFGDs), and wet ESPs (WESPs).
