Trimethoprim (TMP) and sulfamethoxazole (SMX) are bacteriostatic agents, which are co-administered to patients during infection treatment due to their synergetic effects. Once consumed, TMP and SMX end up in wastewater and are directed to municipal wastewater treatment plants (WWTPs) which fail to remove these contaminants from municipal wastewater. The discharge of WWTP effluents containing antibiotics in the environment is a major concern for public health as it contributes to the spread of antimicrobial resistance.

Background: Mechanical ventilation (MV) is a life support method used to treat patients with respiratory failure. High tidal volumes during MV can cause ventilator-induced lung injury (VILI), but also affect other organs, such as the diaphragm (Dia) causing ventilator-induced diaphragmatic dysfunction (VIDD). VIDD is often associated with a complicated course on MV.

In the present study, we investigated whether curcumin administration would interfere with the main renal features of l-NAME-induced hypertension model. For this purpose, we conducted both in vitro and in vivo experiments to evaluate renal indicators of inflammation, oxidative stress, and metalloproteinases (MMPs) expression/activity. Hypertension was induced by l-NAME (70 mg/kg/day), and Wistar rats from both control and hypertensive groups were treated with curcumin (50 or 100 mg/kg/day; gavage) or vehicle for 14 days.

Ruthenium(II) complexes (-) with the general formula [Ru(O-O)(PPh)(bipy)]PF bearing two triphenylphosphine (PPh), bipyridine (bipy) and a series of natural and synthetic β-diketones (O,O) ligands were synthesized and characterized using various analytical techniques. The interaction between the complexes and DNA (CT-DNA) was investigated and demonstrated a weak interaction. The cytotoxicity of the complexes was investigated against breast cancer cells (MDA-MB-231 and MCF-7), lung cancer cells (A549), cisplatin-resistant ovarian cancer cells (A2780), as well as non-tumour lung (MRC-5) and non-tumour breast (MCF-10A) cell lines.

Department of Geophysics, Institute of Astronomy, Geophysics and Atmospheric Sciences, University of São Paulo (USP), São Paulo, SP, Brazil.

The Ediacaran-Cambrian transition documents a critical stage in the diversification of animals. The global fossil record documents the appearance of cloudinomorphs and other shelled tubular organisms followed by non-biomineralized small carbonaceous fossils and by the highly diversified small shelly fossils between ~ 550 and 530 Ma. Here, we report diverse microfossils in thin sections and hand samples from the Ediacaran Bocaina Formation, Brazil, separated into five descriptive categories: elongate solid structures (ES); elongate filled structures (EF); two types of equidimensional structures (EQ 1 and 2) and elongate hollow structures with coiled ends (CE).

Introduction: Vaccines are essential for the prevention and control of several diseases, indeed, monitoring the immune response generated by vaccines is crucial. The immune response generated by vaccination against SARS-CoV-2 in children and adolescents is not well defined regarding to the intensity and medium to long-term duration of a protective immune response, which may point out the need of booster doses and might support the decisions in public health.

Objective: The study aims to evaluate the immunogenicity and safety of inactivated SARS-CoV-2 vaccine (CoronaVac) in a two-dose primary protocol in children and adolescent aging from 3 to 17 years old in Brazil.

In this study, we hypothesized that long-term administration of hesperidin can modulate the inflammatory response and oxidative stress in animals submitted to mechanical ventilation (MV). Twenty-five C57BL/6 male mice were divided into 5 groups: control, MV, animals receiving hesperidin in three doses 10, 25 and 50 mg/kg. The animals received the doses of hesperidin for 30 days via orogastric gavage, and at the end of the period the animals were submitted to MV.

Approaches to safety culture assessment may have many limits if supported exclusively by quantitative methods. Based on this, a research team developed a quantitative-qualitative approach to assess the maturity of the safety culture on an oil platform. To that end, the team sought to develop and test a method consisting of an initial ethnographic phase followed by four other distinct phases: definition of homogeneous groups; production of customized questionnaires; quantitative evaluation; and qualitative assessment.

Article Synopsis
  • The study investigated how N-acetylcysteine (NAC) protects cells and mice from the harmful effects of formaldehyde exposure.
  • Results showed that formaldehyde decreased cell viability, increased reactive oxygen species (ROS), and led to inflammation and oxidative damage in both cell cultures and live mice.
  • NAC administration was found to reduce oxidative stress and inflammatory markers, suggesting it could help prevent airway injury caused by formaldehyde exposure.
