The Toxicity of Poly(acrylonitrile-styrene-butadiene) Microplastics toward Is Associated with Biofragmentation and Oxidative Stress.
Chem Res Toxicol
January 2025
Institute of Chemistry, University of São Paulo, Av. Prof. Lineu Prestes 748, 05508-900 São Paulo, SP, Brazil.
Acrylonitrile-butadiene-styrene (ABS) is a thermoplastic copolymer commonly used in the electronics, automotive, and construction industries. In the aquatic environment, the formation of microplastics from larger-sized plastic waste occurs naturally, induced by physical, chemical, and biological processes that promote the aging of these particles. Here, we investigated the interactions between the freshwater amphipod and ABS microplastics (10-20 μm) (pristine and after accelerated aging) over 7 days of exposure.

Department of Population and Public Health Sciences, Keck School of Medicine, University of Southern California, Los Angeles.
Background And Objectives: Multiple sclerosis (MS)-related disability in Hispanic people with MS is associated with inequities in social determinants of health (SDOH) as measured by composite indices of areal-level census data. Studies of individual-level measures of SDOH are lacking. This study examined the separate and joint effects of person-centered SDOH indicators and an area-level composite on MS disability measures.

Plast Reconstr Surg Glob Open
January 2025
From the Division of Plastic and Reconstructive Surgery, Department of Surgery, Massachusetts General Hospital, Harvard Medical School, Boston, MA.
Background: Most patients undergoing breast surgery with free nipple grafts lose nipple erection (NE) function. This study aimed to evaluate the effect of nerve preservation and reconstruction with targeted nipple-areola complex reinnervation (TNR) on NE following gender-affirming mastectomy with free nipple grafting.
Methods: Patients undergoing gender-affirming mastectomy with free nipple grafts were prospectively enrolled.
Perspectives of clinicians and screening candidates on shared decision-making in prostate cancer screening with the prostate-specific antigen (PSA) test: a qualitative study (PROSHADE study).
BMJ Evid Based Med
December 2024
Department of Public Health, History of Science, and Gynecology, Miguel Hernandez University of Elche Faculty of Medicine, Sant Joan D'Alacant, Comunidad Valenciana, Spain
Objective: The objective of this study is to analyse the perspectives of screening candidates and healthcare professionals on shared decision-making (SDM) in prostate cancer (PCa) screening using the prostate-specific antigen (PSA) test.
Design: Descriptive qualitative study (May-December 2022): six face-to-face focus groups and four semistructured interviews were conducted, transcribed verbatim and thematically analysed using ATLAS.ti software.
Presence of polyketide synthases and nonribosomal peptide synthetase in culturable bacteria associated with Aplysina fulva and Aplysina caissara (Porifera).

Graduate Program in Evolution and Diversity, Federal University of ABC, Av. dos Estados, Bairro Bangu, Santo André, São Paulo, 5001, CEP 09210-580, Brazil.
Culture-dependent and -independent studies have provided access to symbiont genes and the functions they play for host sponges. Thus, this work investigates the diversity, presence of genes of pharmacological interest, biological activities and metabolome of the bacteria isolated from the sponges Aplysina caissara and Aplysina fulva collected on the southwestern Atlantic Coast. The genes for Polyketide Synthases types I and II and Nonribosomal Peptide Synthetases were screened in more than 200 bacterial strains obtained, from which around 40% were putatively novel.
