Gene transcription in the oyster Crassostrea gigas exposed to environmental concentrations of the UV filter Benzophenone-3.

Personal care products (PCPs), such as sunscreens, are usually found in various aquatic ecosystems at low concentrations (ng l to µg l). However, there is limited information regarding their effects on marine bivalves. Therefore, the aim of this study was to evaluate the sublethal effects of environmental concentrations (1 and 100 µg l) of benzophenone-3 (BP-3) in Crassostrea gigas oysters after 1 and 7 days of exposure.

Anterior component separation techniques: is it necessary to preserve the perforators? a systematic review and meta-analysis.

Background: Anterior component separation (ACS), or Ramirez component separation technique, is an established technique still used by surgeons to repair a ventral hernia. Compared with other ventral hernia repair techniques, recent studies about ACS show more postoperative complications like wound breakdown, wound infection, hematoma, skin necrosis, seroma, and recurrence. Our study aims to compare the ACS technique with the preservation perforator technique and verify if the perforator preservation technique can decrease postoperative complications.

Characterization of acetylcholinesterase and carboxylesterases in the mangrove oyster Crassostrea gasar as biomarkers of exposure to environmental pollutants.

Brazil is one of the world's leading consumers of agricultural pesticides, highlighting the urgent need to identify responsive biomarkers as diagnostic and prognostic tools for monitoring aquatic pollution. Acetylcholinesterase (AChE) and carboxylesterases (CbE) are B-esterases enzymes expressed in several organisms. AChE plays an essential role in neural transmission at cholinergic synapses, while CbE are directly involved in the detoxification of organic pollutants, including organophosphorus pesticides.

A sensitive electrochemical DNA biosensor for detecting the genome of a plant growth-promoting bacteria.

The challenge of increasing food production while maintaining environmental sustainability can be addressed by using biofertilizers such as Azospirillum, which can enhance plant growth and colonize more than 100 plant species. The success of this biotechnology depends on the amount of plant growth-promoting bacteria associated with the plant during crop development. However, monitoring bacterial population dynamics after inoculation requires time-consuming, laborious, and costly procedures.

[Healthcare-Associated Infections in Pediatric Patients: A Decade of Experience in an Intensive Care Unit].

Introduction: Healthcare-associated infections are an important cause of morbidity and mortality in the pediatric population and a growing problem in intensive care services. However, limited data are available on these infections in the Portuguese pediatric population. This study aimed to estimate its prevalence rate in a Portuguese pediatric intensive care unit, identifying the most frequent microorganisms and their antibiotic resistance profiles.
