Metformin reverses infertility in a mouse model of endometriosis: unveiling disease pathways and implications for future clinical approaches.

Research Question: Does metformin reverse endometriosis-associated infertility?

Design: Endometriosis was induced by transplanting uterus fragments from B6CBAF1 mice into recipients of the same strain. The mice were divided into groups: endometriosis (End, n = 24), sham-operated (Sham, n = 12), endometriosis with metformin (0.5mg/ml) orally administered for 3 months (EndMet, n = 21) and sham-operated metformin-treated (ShamMet, n = 16).

Predicted environmental concentration (PEC), environmental risk assessment (ERA) and prioritization of antiretroviral drugs (ARVs) in seawater from Guarujá (Brazilian coastal zone).

The antiretroviral therapy program's success in managing the human immunodeficiency virus (HIV) has inadvertently led to the release of antiretrovirals (ARVs) into worldwide aquatic ecosystems. However, few studies investigated the risks of ARV loadings that flow continuously to the marine waters of South America (such as Brazil). Against this backdrop, the aims of this study were: (i) to estimate the Predicted Environmental Concentration (PEC) of thirteen ARVs worldwide used in HIV treatment, and which are frequently disposed of in the marine aquatic ecosystems of Guarujá, São Paulo coastline, Brazil.

Complementary Strategies to Identify Differentially Expressed Genes in the Choroid Plexus of Patients with Progressive Multiple Sclerosis.

Multiple sclerosis (MS) is a neurological disease causing myelin and axon damage through inflammatory and autoimmune processes. Despite affecting millions worldwide, understanding its genetic pathways remains limited. The choroid plexus (ChP) has been studied in neurodegenerative processes and diseases like MS due to its dysregulation, yet its role in MS pathophysiology remains unclear.

Qualitative and quantitative analysis of reduced bed position acquisition time on FDG PET image quality.

The study aim was to evaluate whether reducing bed position acquisition time would result in significant detriment to image quality. Secondary aims were to compare effect of time of flight (TOF) and Q.Clear reconstructions and patient BMI on image quality.

The impact of community pharmacies on equity in access to professional rapid antigen testing for SARS-CoV-2 in Portugal.

Introduction: Amid the COVID-19 pandemic, various public health measures were adopted to reduce the transmission risk, including the full reimbursement of SARS-CoV-2 professional rapid antigen detection tests (Ag-RDT) conducted in clinical pathology laboratories, community pharmacies (CPs), and other authorized entities. This study aimed to assess the impact of integrating CPs into the Portuguese National Health Service (NHS) testing strategy on the capacity of professional Ag-RDT delivery, and to compare the equity in testing access with and without CPs participation.

Methods: This analytical cross-sectional study assessed the impact of adding CPs into the testing strategy based on two main outcomes by municipality: (i) average distance (in Kilometres) of the population to the nearest Ag-RDT site; and (ii) the average number of weekly hours available to testing per 1,000 inhabitants, as of January 31, 2022.
