Introduction: The intracanal antibacterial effectiveness of a bioceramic medication was compared with calcium hydroxide pastes in different vehicles.

Methods: Extracted mandibular incisors with a single long oval canal were selected and distributed into 5 groups based on anatomically paired microcomputed tomographic analyses. The root canals were prepared up to an instrument size 35/04 and contaminated for 30 days with a mixed bacterial culture from subgingival biofilm added with Enterococcus faecalis.

Article Synopsis
  • - The article explores how PrEP and the concept of undetectable viral load creating a framework (UVL=U) have changed the dating and sexual experiences of young gay men living with HIV in Brazil.
  • - Interviews with nine young people (ages 18-29) reveal that those newly diagnosed are more worried about HIV transmission and stigma, while those who have lived with HIV longer feel more at ease with these new biomedical advances.
  • - The findings highlight the need for inclusive public health policies that go beyond just medical solutions, addressing stigma, enhancing knowledge about HIV prevention, and respecting individuals' choices in managing their sexual health.

Introduction: Septic shock, a life-threatening condition, can result in cerebral dysfunction and heightened mortality rates. In these patients, disturbances in cerebral hemodynamics, as reflected by impairment of myogenic cerebral autoregulation (CA), metabolic regulation, expressed by critical closing pressure (CrCP) and reductions in intracranial compliance (ICC), can adversely impact septic shock outcomes. The general recommendation is to maintain a target mean arterial pressure (MAP) of 65 mmHg but the effect of different MAP targets on cerebral hemodynamics in these patients is not clear and optimal targets might be dependent on the status of CA.

Desertification is a major threat to biodiversity in arid areas of the world, partly because many organisms in these regions already exist at or near the limits of their movement and physiology. Here, we used molecular data to investigate patterns of persistence and dispersal in an ecologically and economically important carpenter bee ( Lepeletier) found throughout the semiarid Caatinga region of Brazil. We used a genome-wide approach (double digest restriction-site associated DNA, ddRAD) to gather genetic data from bees sampled from eight sites within a semiarid region subject to desertification in Northeastern Brazil.
