Promising strategies employing nucleic acids as antimicrobial drugs

Antimicrobial resistance (AMR) is a growing concern because it causes microorganisms to develop resistance to drugs commonly used to treat infections. This results in increased difficulty in treating infections, leading to higher mortality rates and significant economic effects. Investing in new antimicrobial agents is, therefore, necessary to prevent and control AMR. Antimicrobial nucleic acids have arisen as ...

Assessment of indoor air exposure among newborns and their mothers: Levels and ...

Significant efforts have been directed towards addressing the adverse health effects of atmospheric particles, emphasizing the relevance of indoor exposure. Homes represent an indoor environment where human spend the majority of their time. Thus, the objective of this work was to concurrently assess different matrix of indoor particles considering both mass (PM10, PM2.5) and number (N20-1000) concentrations in ...

Assessment of indoor air exposure at residential homes: Inhalation dose and lun...

Accurate assessment of particulate matter (PM) dose and respiratory deposition is essential to better understand the risks of exposure to PM and, consequently, to develop the respective risk-control strategies. In homes, this is especially relevant in regards to ultrafine particles (UFP; <0.1 μm) which origin in these environments is mostly due to indoor sources. Thus, this study aimed to estimate inhalation do...

Wood smoke exposure of Portuguese wildland firefighters: DNA and oxidative dama...

Portugal is among the European Union countries most devastated by forest fires each year. In the last three decades, more than 3.8 million hectares of forest were burned. Wildland firefighters are exposed to a variety of hazards, including many toxic combustion products that may lead to deleterious health effects. Epidemiological studies showed a positive association between firefighting and several chronic dis...

Occupational exposure of firefighters to polycyclic aromatic hydrocarbons in non-...

This work aims to characterize personal exposure of firefighters to polycyclic aromatic hydrocarbons (PAHs) in non-fire work environments (fire stations), and assesses the respective risks. Eighteen PAHs (16 considered by USEPA as priority pollutants, dibenzo[a,l]pyrene and benzo[j]fluoranthene) were monitored in breathing zones of workers at five Portuguese fire stations during a normal shift. The obtained lev...

Estudo comparativo, aleatorizado, em dupla ocultação, de orlistat versus placeb...

INTRODUCTION: Obesity is a chronic disease and a serious health problem that leads to increased prevalence of diabetes, hypertension, dyslipidemia and gallbladder disease. OBJECTIVE: To evaluate the efficacy of orlistat for weight loss and improved lipid profile compared to placebo in obese patients with hypercholesterolemia, treated over a period of 6 months. METHODOLOGY: In a 6-month, multicenter (10 centers ...
