Monoclinic BiVO(4) crystals with preferentially exposed (040) facets were hydrothermally synthesized by using a trace amount of TiCl(3) as the directing agent; this function was confirmed by X-ray diffraction patterns (XRD) and high-resolution transmission electron microscopy (HRTEM). The effects of the directing agent TiCl(3) and the pH values applied during synthesis have been studied, and the optimized BiVO(4) sample with highly exposed (040) facet could be obtained by using 1.2 at.% of TiCl(3) as the directing agent at a pH value of 2. Some complementary techniques were also applied to exclude the effects of the structural and physical property changes, such as surface area and hydrophilicity. The photocatalytic activity of oxygen evolution on BiVO(4) is found to be proportionally correlated with the exposed surfaces of the (040) facet. It is assumed that the active sites with a BiV(4) structure on the exposed (040) facet is assigned to be responsible for the high activity of O(2) evolution.

Decabromodiphenyl ethane (DBDPE), a key alternative to deca-BDE (BDE-209), has been ubiquitous in the receiving ecosystem. However, little is known about its uptake process and fate in plants. Here, the plant absorption, distribution, and metabolism of C-DBDPE under two distinct exposure pathways (i.

Background: The present study is a systematic review and meta-analysis aiming to investigate the effects of alcohol consumption on male sex hormones in humans.
Methods: We conducted searches on PubMed, Scopus, Science Direct, and Google Scholar from June 2020 to June 2022. We included observational studies (cohorts, case-controls, and cross-sectional studies) comparing FSH, LH, or testosterone levels in alcohol consumers versus non-consumers.
Discontinuation of anticoagulants and occurrence of bleeding and thromboembolic events in vitamin K antagonist users with a life-limiting disease.

Hematology, Erasmus University Medical Center, Rotterdam, Netherlands.
Background: Data on risks and benefits of long-term anticoagulants in patients with a life-limiting disease are limited. This cohort study aims to describe (dis)continuation of anticoagulants and incidences of bleeding and thromboembolic events in vitamin K antagonist (VKA) users with a life-limiting disease.
Methods: Data from five Dutch anticoagulation clinics were linked to data from Statistics Netherlands and the Netherlands Cancer registry.

Brazilian garimpeiros are a highly hard-to-reach and mobile population, with little access to basic hygiene and health services, and have been crossing the border to work irregularly in gold mines in French Guiana since the 1990s. This study aimed to characterize this population and identify their main health problems. A cross-sectional study was carried out in the municipality of Oiapoque-AP, with two surveys: before (2018) and after (2019) the implementation of Malakit.

Background: The mental health of children living in humanitarian crisis situations is a major issue. Post-traumatic stress disorder (PTSD) causes great psychological suffering and has negative consequences on children's development. The aim of the study was to analyze retrospective data collected in a mental health and psychosocial support program for children in the Central African Republic, and to compare results of two trauma-focused treatment interventions: the narrative protocol Action contre la Faim (ACF)/KONO; and the EMDR-based Group Trauma Episode Protocol (G-TEP).
