Outdoor Pollution Comparison Between Bucharest and Its Outskirts Using Mobile Laboratory.
Int J Environ Res Public Health
November 2024
This study presents a modern mobile laboratory to monitor outdoor air quality in Bucharest, Romania, with a focus on pollutants associated with transportation. Particulate matter (PM., PM), carbon monoxide (CO), ozone (O), sulfur dioxide (SO), nitrogen oxides (NO, NO), and BTEX compounds (benzene, toluene, ethylbenzene, and xylenes) were among the significant pollutants that were examined in the lab.

We present our current analysis and tests on a series of different BHR-retrieved prostheses after premature failure. Relevant clinical data, such as X-ray investigations and intraoperative images for clinical case studies, were analyzed to better understand all factors involved in BHR prosthesis failure.

- Dysregulation of lipid metabolism can cause dyslipidemia and obesity, which contribute significantly to cardiovascular disease, prompting this study to explore six plant extracts (ACE-, RSE-, CHE-, CE-, AGE-, CGE-) as potential therapies for these conditions.
- The study found that RSE contained the highest levels of polyphenols and phenolcarboxylic acids, while CGE exhibited significant concentrations of flavones; both rosemary and hawthorn extracts showed notable antioxidant properties.
- Using computational methods, the research suggested that rosmarinic acid and chlorogenic acid could effectively interact with the active site of carbonic anhydrase 5A, indicating their potential as anti-obesity agents, warranting further experimental validation in vivo.
Preparation and Preliminary Analysis of Several Nanoformulations Based on Plant Extracts and Biodegradable Polymers as a Possible Application for Chronic Venous Disease Therapy.
Polymers (Basel)
May 2024
Nanotechnology is one of the newest directions for plant-based therapies. Chronic venous disease often predisposes to long-term and invasive treatment. This research focused on the inclusion of vegetal extracts from (SE), (CE), and (GE) in formulations with PHB and PLGA polymers and their physicochemical characterization as a preliminary stage for possible use in the development of a complex therapeutic product.

This study focuses on the release curves and extractable yields of francium, radium and actinium isotopes. The ion source temperature was varied in order to study the relative contributions of surface and laser ionization to the production of the actinium ion beams.
