Investigation of size-segregated particulate matter and carbonaceous components in Phnom Penh, Cambodia.
Environ Sci Pollut Res Int

Article Synopsis
- - This study examined carbon-based components of particulate matter (PM) in three urban locations in Phnom Penh, Cambodia: a university, a governmental institution, and a residential area near a landfill, using specialized sampling techniques to analyze ultrafine particles (UFPs).
- - Results showed that while mass concentration of PM didn't significantly differ between weekdays and weekends, the profiles varied across locations; the university had high levels of elemental carbon (EC) suggesting vehicular emissions, whereas the landfill site showed higher organic carbon (OC) due to waste-related activities.
- - Additionally, the Ministry of Environment site had a balanced OC and EC profile, influenced by nearby natural factors, and overall, both local emissions and transboundary influences from agricultural burning
Background: The Government of Cambodia established the village health support groups (VHSGs) in 2003 to facilitate primary healthcare activities, including maternal and child health (MCH) services. However, VHSGs face several challenges that hinder them from performing optimally, including a lack of regular structured training and remuneration and limited and inconsistent support and supervision from the health centers (HCs). This implementation research aims to develop, implement, and evaluate a digital health intervention to improve the performance of VHSGs through better support and supervision and increase the MCH service coverage in rural Cambodia.

Remarkably though, the prevalence of multidrug-resistant TB (MDR-TB) remains low. We explored the genetic diversity of Mycobacterium tuberculosis (MTB) circulating in this unique setting using whole-genome sequencing (WGS).

Design: Qualitative cross-sectional study.
Setting: Urban, semiurban, and rural areas in Cambodia.
A new aporphine glycoside (1), named 'angkorwatine', and eight known alkaloids: oblongine (2), stepharine (3), asimilobine-β-d-glucopyranoside (4), isocorydine (5), tetrahydropalmatine (THP) (6), jatrorrhizine (7), palmatine (PAL) (8), and roemerine (ROE) (9) were simultaneously isolated from the tuber of Stephania cambodica. The development and validation of UHPLC-DAD method was carried out for the quantification of marker compounds (PAL, ROE, THP) of S. cambodica.
