Smoking-attributable mortality in Portugal and its regions in 2019.

Introduction And Objectives: Timely regional-specific estimates of smoking-attributable mortality (SAM) are crucial for healthcare planning and tobacco control advocacy. Currently, this information is lacking in Portugal. The aim of this study was to estimate SAM by region in 2019 among the Portuguese population aged ≥35 years.

Synthesis of 1,10-Phenanthroline-2,9-bistriazoles: Evaluation as G-Quadruplex Binders and Anti-Tumor Activity.

Novel 1,10-phenanthroline-2,9-bistriazoles derivatives have been synthesized by copper-catalyzed azide/alkyne cycloaddition reactions and assessed for their ability to bind and stabilize G-quadruplex (G4) structures. Ten novel compounds were evaluated using Förster resonance energy transfer (FRET) melting, circular dichroism (CD), and fluorescence spectroscopy on several G4 sequences. Biophysical characterization led to the identification of compounds 4 a, 4 b, and 5 b as good G4 ligands of KRAS G4 sequences.

Biophysical characterization of microRNA mixtures based on Molecular Beacons.

Diverse studies have shown a relationship between dysregulated microRNAs (miRNAs), including miRNA-29b and miRNA-9, and several diseases. So, it is hypothesized that miRNAs can be studied as potential agents to be exploited in biomedical applications, due to their ability to take part in gene expression regulation at a post-transcriptional level. Considering the possibility of using miRNAs, it is important to characterize and validate this bioproduct, structurally and functionally.

TH1 Cell Frequency and Neutrophil-to-Lymphocyte Ratio in Hemodialysis: Potential Contributions to Patient Monitoring.

Patients undergoing hemodialysis (HD) often exhibit an impaired cellular immune response, which may contribute to an increased susceptibility to infections and other complications. Th1 cells, a subset of T-helper cells, play a crucial role in cellular immunity. However, the modulation of Th1 cells by HD treatment remains unclear.

Plant-Based Beverages: Consumption Habits, Perception and Knowledge on a Sample of Portuguese Citizens.

Plant-based beverages (PBB) consumption has increased significantly worldwide due to an interest in vegetarian/vegan diets, taste preferences, health and ethical and environmental issues. Therefore, this study intends to investigate consumption habits, consumer preferences and consumers' level of knowledge about PBB. In this study, a voluntary, anonymous questionnaire survey was applied to a sample of participants from Portugal.

Exploring flagellar contributions to motility and virulence in Arcobacter butzleri.

Flagella is a well-known bacterial structure crucial for motility, which also plays pivotal roles in pathogenesis. Arcobacter butzleri, an enteropathogen, possesses a distinctive polar flagellum whose functional aspects remain largely unexplored. Upon investigating the factors influencing A.

SGLT2i and GLP1RA effects in patients followed in a hospital diabetology consultation.

Background: We aimed to investigate the effects of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1RA) in patients with type 2 diabetes mellitus (T2DM) in clinical practice.

Research Design And Methods: A total of 340 patients were included. Data on age, gender, antidiabetic medications, and bioanalytical parameters were collected at baseline and one year later.

Renewable Photo-Cross-Linkable Polyester-Based Biomaterials: Synthesis, Characterization, and Cytocompatibility Assessment.

The present work consist of the synthesis of photo-cross-linkable materials, based on unsaturated polyesters (UPs), synthesized from biobased monomers from renewable sources such as itaconic acid and 1,4-butanediol. The UPs were characterized to assess the influence of polycondensation reaction temperature and cross-linking time on their final properties. For this purpose, different UV irradiation exposure periods were tested.

Characterizing the most demanding passages of kinematic and mechanical activity in elite football: a multifactorial approach.

This study investigated the 5-minute most demanding passages (MDP) of kinematic (distance covered) and mechanical (acceleration and deceleration) activities in elite male football according to multifactorial criterion performance variables. Global positioning systems data were collected from 39 players across 45 matches in the Swedish first division (n = 329 observations). The multifactorial kinematic variable (MDPk) was composed of the concurrent distances covered at moderate-speed running, high-speed running, and sprinting distances, and the multifactorial mechanical (MDPm) considered the concurrent occurrences of high-intensity acceleration and deceleration activities.

The impact of exercise intensity on depression in fibromyalgia: a randomized controlled trial.

Background: Fibromyalgia (FM) is characterized by widespread chronic pain. Although pain is the main symptom, approximately 90% of patients have depression. This study aimed to analyze the effects of Resistance Training (RT) with low and high intensity on depression in patients with FM.

Mentha aquatica (Water Mint) as a Source of Active Pharmaceutical and Cosmetic Ingredients: A Critical Review.

Mentha aquatica L., or water mint, is an important member of the Mentha genus, and has long been used in traditional medicine, mainly to treat respiratory diseases such as the common cold. Nevertheless, although over the years many studies have shown that it's potential grows beyond this use, a review that highlights M.

The green synthesis of carbon dots (CDs) from natural sources is a challenging goal. Herein CDs are produced from Agapanthus africanus (L.) Hoffmann leaves by carbonization at 200/300 °C for 2/3 h.

Improving Skin Cancer Treatment by Dual Drug Co-Encapsulation into Liposomal Systems-An Integrated Approach towards Anticancer Synergism and Targeted Delivery.

Skin cancer is a high-incidence complex disease, representing a significant challenge to public health, with conventional treatments often having limited efficacy and severe side effects. Nanocarrier-based systems provide a controlled, targeted, and efficacious methodology for the delivery of therapeutic molecules, leading to enhanced therapeutic efficacy, the protection of active molecules from degradation, and reduced adverse effects. These features are even more relevant in dual-loaded nanosystems, with the encapsulated drug molecules leading to synergistic antitumor effects.

High-Risk HPV Detection in Paraffin-Embedded Tissue from Cervical Lesions.

Background: Human papillomavirus (HPV), a leading cause of cervical cancer, is present in most cases of the disease and ranks as the fourth most common cancer in women globally. Among the HPV types, fourteen (HPV 16/18/31/33/35/39/45/51/52/56/58/59/66/68) are recognized as high-risk (hrHPV), each with varying levels of oncogenic potential. Detecting and genotyping these hrHPV types in cervical lesions is crucial, requiring the development of new diagnostic methods.

Religious Affiliation, Internalized Homonegativity and Depressive Symptoms: Unveiling Mental Health Inequalities among Brazilian Gay Men.

Introduction: Different religious narratives associate same-sex sexuality, in its various manifestations, with moral deviation or sin. Gay men who are socialized in more religious communities appear to experience and internalize greater levels of homonegativity, as well as to present greater indicators of depressive symptoms. The purpose of this study was to evaluate indicators of perceived homonegativity in the community and internalized, and signs/symptoms of depression reported by Brazilian gay men with a nominal religion and compare them to those reported by Atheists or Agnostics.

A new approach for extracellular RNA recovery from Rhodovulum sulfidophilum.

The development of RNA-based drugs is highly pursued due to the possibility of creating viable and effective therapies. However, their translation to clinical practice strongly depends on efficient technologies to produce substantial levels of these biomolecules, with high purity and high quality. RNAs are commonly produced by chemical or enzymatic methods, displaying these limitations.

Risks of oral anticoagulants: Analysis of adverse drug reactions reported to the Portuguese National Pharmacovigilance System.

Cardiovascular diseases are the leading cause of death globally, making the use of oral anticoagulants for prevention increasingly important. Historically, warfarin has played a significant role in this context. In recent years, introduction of new oral anticoagulants, such as rivaroxaban, apixaban, dabigatran, and edoxaban, has been seen.
