Obesity is a global epidemic often associated with serious medical complications such as diabetes, hypertension and metabolic dysfunction-associated steatohepatitis. Considering the multifactorial nature of these diseases, medicinal plants could be a valuable therapeutic strategy as their phytoconstituents interact with multiple and relevant biological targets. In this context, Ilex paraguariensis emerges as a potential alternative to treat obesity and associated metabolic diseases since several studies have demonstrated its anti-inflammatory, anti-obesity and anti-diabetic effects.

With praziquantel being the sole available drug for schistosomiasis, identifying novel anthelmintic agents is imperative. A chemical investigation of the fruiting body of the bioluminescent mushroom Berk. resulted in the isolation of new conjugated long-chain fatty acids (8,10,12,13)-12,13-dihydroxy-7-oxo-octadeca-8,10-dienoic acid () and (7,8,9,11)-7,8-dihydroxy-13-oxo-octadeca-9,11-dienoic acid () and three previously described compounds, (7,8,9)-7,8-dihydroxyoctadec-9-enoic acid (), (2)-dec-2-ene-1,10-dioic acid (), and a ketolactone marasmeno-1,15-dione ().

Cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) is a receptor that inhibits the activity of T cells. The CTLA-4 gene consists of four different exons that enable four different isoforms of CTLA-4 to be generated through alternative splicing. Although sCTLA-4 might impede the therapeutic effect of anti-CTLA-4 treatments, the role of sCTLA-4 in the tumor microenvironment (TME) is not well understood.

Brazil's COVID-19 response has faced challenges due to the continuous emergence of variants of concern (VOCs), emphasizing the need for ongoing genomic surveillance and retrospective analyses of past epidemic waves to reassess and fine tune containment protocols. Rio Grande do Sul (RS), Brazil's southernmost state, has international borders and trades with Argentina and Uruguay, along with significant domestic connections within Brazil. The identification of source and sink transmission chains at national and international scales can identify main hubs and pathways to target future interventions.

Developing process intensification technologies to treat Petroleum Wastewater (PW) is crucial to maintaining the economic and environmental safety of the process. Therefore, a one-step combination of adsorption and flotation was tested in this study for the first time to remove organic compounds from PW using a biochar-derived composite. High salinity PW samples from Brazilian oil wells were used to test the efficiency of the new method.

Background: Infections by carbapenem-resistant Pseudomonas aeruginosa (CRPA) have been associated with high morbidity and mortality among solid organ recipients.

Objectives: To delineate the epidemiological and molecular characteristics of a recurrent outbreak of imipenem (IMP)-producing P. aeruginosa (CRPA) among kidney transplant (KT) recipient METHODS: We described a recurring CRPA outbreak in a KT ward, divided into two periods: before unit closure (Feb 2019-2020) and after reopening (Aug 2020-Dec 2023).

Article Synopsis
  • This study used a rabbit model to test a new dental implant design (Collo group) with a concave cervical section against a standard implant design (Control group), focusing on implant stability and bone integration.
  • The implants were evaluated by measuring initial stability (ISQ) immediately after insertion and at later time points, along with analyzing bone-implant contact (BIC%) and tissue area fraction occupancy (TAFO%) through histological sections at 3 and 4 weeks post-implantation.
  • Results indicated that the Collo group demonstrated significantly greater stability and better integration with surrounding bone over time compared to the Control group, suggesting potential advantages of the new implant design.

Background: Rebound pain is believed to involve both nociceptive pain due to insufficient analgesia and hyperalgesia induced by regional anesthesia. Adjuvant's addition could prevent rebound pain. This study aimed to determine if the addition of dexamethasone or clonidine to local anesthetic when performing interscalene block could prevent rebound pain.

In response to stresses on water demands, some regions augment conventional drinking water sources with alternative water supplies such as desalinated seawater and reclaimed wastewater. The advanced treatment of wastewater by reverse osmosis, microfiltration, and advanced oxidation processes can produce high quality water for potable uses. However, if not appropriately stabilized, the resulting water can be corrosive to metal-based distribution pipes and plumbing materials.

The resurgent navigation project known as the Hidrovia Paraguay-Paraná threatens the integrity of the Pantanal, the world's largest wetland, which is considered a biome of its own. Intensive barge navigation is intended to transport crops (soybean, sugar, corn) and cement, iron and manganese from areas of production in Brazil, Paraguay and Bolivia to the oceanic ports of the Plata River. This short communication assembles the information available on the potential impacts of the planned deepening of the natural channel of the Paraguay River in its ~700 km-long upper section.
