Immune biomarkers in cases of recurrent pregnancy loss and recurrent implantation failure.

Reproductive failures, such as recurrent pregnancy loss (RPL) and recurrent implantation failures (RIF) are a major challenge for reproductive medicine. The current management of RPL and RIF cases identifies some causes for unsuccessful pregnancy in up to half of patients. Several studies have suggested that immune disorders are responsible for an important portion of unexplained cases of RPL and RIF.

Transforming the Health Research Workforce in Mozambique: Achievements of the Mozambique Institute for Health Education and Research (MIHER) over a 13‑Year Journey.

African research capacity is challenged by insufficient infrastructure to solicit and manage grants from local and international funding agencies. The manuscript provides an overview and discusses lessons learned about the pioneering role of the Mozambique Institute for Health Education and Research (MIHER) as the first research support center (RSC) in supporting the management of research grants in Mozambique, emphasizing its impact on research capacity development. Using mixed methods, data were comprehensively collected to identify MIHER's primary achievements from 2010 to 2023.

The blue palette of life: A comprehensive review of natural bluish colorants with potential commercial applications.

Considering the growing interest for safer, environmentally friendly and healthier products, the search for natural colorants to replace their synthetic has been raised. This is particularly challenging for the rare and usually unstable bluish coloring substances. This comprehensive review describes several bluish pigments which can be obtained from natural sources (plants and mostly microorganisms), covering less known molecules to well established compounds (although no focus is given for anthocyanins).

Mass Spectrometry-Based Metabolomics Reveals a Salivary Signature for Low-Severity COVID-19.

Omics approaches were extensively applied during the coronavirus disease 2019 (COVID-19) pandemic to understand the disease, identify biomarkers with diagnostic and prognostic value, and discover new molecular targets for medications. COVID-19 continues to challenge the healthcare system as the virus mutates, becoming more transmissible or adept at evading the immune system, causing resurgent epidemic waves over the last few years. In this study, we used saliva from volunteers who were negative and positive for COVID-19 when Omicron and its variants became dominant.

The Action of Colchicine in Patients with Metabolic Syndrome and Obesity: Perspectives and Challenges.

Colchicine is an alkaloid traditionally used to treat inflammatory conditions such as gout and familial Mediterranean fever. Currently, there are proposals for the use of this drug in several other situations, such as cardiovascular and liver diseases and diabetes. In this study, the current literature on the potential of colchicine in the treatment of obesity and metabolic syndrome (MS) was evaluated.

The presence of NSAIDs may affect the binding capacity of serum albumin to the natural products hymecromone and umbelliferone.

The natural products 7-hydroxycoumarin (7HC) and 7-hydroxy-4-methylcoumarin (7H4MC), known as umbelliferone and hymecromone, respectively, are one of the simplest structural examples from coumarin's family, showing several biological activities. Bovine serum albumin (BSA) is the main model protein used in laboratory experiments to characterize the biophysical capacity of potential drugs to be carried until the target in the bloodstream. Thus, the interaction BSA:7HC and BSA:7H4MC was biophysically characterized by circular dichroism (CD), steady-state, and time-resolved fluorescence techniques combined with molecular docking calculations via cross-docking approach to better correlate with the biological medium.

Blown spun fibers-based colorimetric sensor for detecting trace zinc in seminal fluid.

Rapid and accurate analysis of zinc in seminal fluid is an important tool for male infertility diagnosis and forensic investigation of sexual assault. Among the traditional techniques employed for this purpose, colorimetric solid-state sensors offer a simple and efficient alternative for screening this analyte. Herein, we evaluated the feasibility of using solution blow spinning as a fast, simple, and cost-effective method to develop porous membranes that can be manufactured as low-cost colorimetric solid-state sensing materials.

Mindfulness and trial-based cognitive therapy for the psychological well-being in the judiciary: A controlled and randomized study protocol.

Introduction: The judiciary sector faces high absenteeism due to mental health issues, yet applying effective therapies like mindfulness and trial-based cognitive therapy (TBCT) remains unexplored.

Objectives: Develop and apply Mindfulness-Integrated Trial-Based Cognitive Therapy (M-TBCT) in the judiciary to assess its acceptability, feasibility, and efficacy in enhancing psychological well-being and reducing depression, anxiety, and improving self-care.

Methods: Conduct a controlled, randomized study in two phases: Phase 1 involves a pilot study to structure the M-TBCT protocol and test its acceptability and feasibility in the judiciary ( = 30); Phase 2, an efficacy trial with 90 participants, comparing M-TBCT to a waitlist.

Satisfactory Levels of Functionality and Quality of Life in Caregivers of Patients with Bipolar Disorder: Is this Possible?

Objectives: To measure the levels of functionality and QoL of caregivers of patients with BD, investigating the association between them, as well as the relationship with clinical and sociodemographic data of these caregivers.

Method: A cross-sectional study was conducted between 2020 and 2022 with caregivers of patients with BD treated in an outpatient clinic of a university hospital. The following instruments were applied: Clinical and sociodemographic questionnaire, WHODAS 2.

Phase angle and body composition in long-term type 1 diabetes in adults: a comparative study in a Brazilian public reference outpatient clinic.

Introduction: Type 1 Diabetes Mellitus (DM1) affects a small percentage of the population. Nevertheless, its prevalence is currently growing with alarming data on uncontrolled cases. The importance of body composition and Phase Angle (PA), assessed by Bioelectrical Impedance (BIA), in long- term DM1 patients lies in the fact that alterations in cellular integrity and body compartments may affect risk profiles and metabolic control.

Lapachol, a natural food component, interacts with human serum albumin: Insights of its impact on the pharmacokinetics of clinically used drugs.

Lapachol (LAP), a natural 1,4-naphthoquinone used in popular medicine in South America, is an antioxidant and antimicrobial compound in teas and infusions and used as a food additive; however, its interactive profile with the main protein carrier of compounds in the human bloodstream (human serum albumin, HSA) was not still characterized. Additionally, the impact of LAP in binding clinically drugs to albumin is still unknown. Thus, the present work describes the interaction HSA:LAP using different biophysical techniques, i.

Cellulose processing using ionic liquids: An analysis of patents and technological trends.

The production of cellulose derivatives using ionic liquid (IL) as solvents and catalysts has become prominent over the last few years, since the process eliminates the use of toxic substances. This study aimed to map and understand the trends in cellulose processing using ILs by a patent analytic approach and technology life cycle modeling.

Use of long-term underwater camera surveillance to assess the effects of the largest Amazonian hydroelectric dam on fish communities.

The increase in the construction of mega dams in tropical basins is considered a threat to freshwater fish diversity. Although difficult to detect in conventional monitoring programs, rheophilic species and those reliant on shallow habitats comprise a large proportion of fish diversity in tropical basins and are among the most sensitive species to hydropower impacts. We used Baited Remote Underwater Video (BRUV), an innovative, non-invasive sampling technique, to record the impacts caused by Belo Monte, the third largest hydropower project in the world, on fishes inhabiting fast waters in the Xingu River.
