Oligostyrylbenzene Derivatives with Antiparasitic and Antibacterial Activity as Potent G-Quadruplex Ligands.

G-quadruplexes (G4s) are non-canonical secondary structures that play a crucial role in the regulation of genetic expression. This study explores the interaction between G4s and a small family of oligostyrylbenzene (OSB) derivatives, characterized by tris(styryl)benzene and tetrastyrylbenzene backbones, functionalized with either trimethylammonium or 1-methylpyridinium groups. Initially identified as DNA ligands, these OSB derivatives have now been recognized as potent G4 binders, surpassing in binding affinity commercially available ligands such as pyridostatin and displaying good selectivity for G4s over duplex DNA.

Mechanical Behaviour and Microstructural Analysis of Earthen Materials Reinforced with Intensive Agricultural By-Products and Binders.

Modern construction is largely dependent on steel and concrete, with natural materials such as earth being significantly underutilised. Despite its sustainability and accessibility, earth is not being used to its full potential in developed countries. This study explores innovative building materials using Alhambra Formation soil (Granada, Spain) reinforced with difficult-to-recycle agricultural waste: polypropylene fibres contaminated with organic matter and leachates.

Effects of High-Intensity Interval Training on Blood Pressure Levels in Hypertensive Patients: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

Objective: This systematic review and meta-analysis aimed to (I) evaluate the evidence on the effects of high-intensity interval training (HIIT) on systolic blood pressure (SBP) and diastolic blood pressure (DBP) in hypertensive patients; (II) determine whether HIIT impacts SBP and DBP differently; and (III) assess the clinical relevance of these effects.

Methods: A comprehensive search was conducted across multiple electronic databases, resulting in the inclusion of seven randomized clinical trials in the meta-analysis. The outcomes were analyzed using random-effects models to compute mean differences (MD) and standardized mean differences (SMD) for SBP and DBP.

Hydroxyproline in Urine Microvesicles as a Biomarker of Fibrosis in the Renal Transplant Patient.

The aim of this study was to assess hydroxyproline in urine microvesicles as a marker of fibrosis in the renal transplant patient.

Efficacy of the reGENER@r Program on Socio-Emotional Skills and Sexist Beliefs in Perpetrators of Gender-Based Violence: A Pilot Study in Spain.

Background: Gender-based violence (GBV) is one of the most pronounced expressions of the unequal power relations between women and men. As a tool for action against this phenomenon, psychological intervention programs for perpetrators of GVB are offered. This is how reGENER@r was born; it is a two-month program based on psychoeducational and cognitive-behavioral strategies that is part of the alternative measures to GBV-related prison sentences.

Loss of Heterozygosity (LOH) Affecting HLA Genes in Breast Cancer: Clinical Relevance and Therapeutic Opportunities.

Major histocompatibility complex (MHC) class-I molecules (or Human Leucocyte Antigen class-I) play a key role in adaptive immunity against cancer. They present specific tumor neoantigens to cytotoxic T cells and provoke an antitumor cytotoxic response. The total or partial loss of HLA molecules can inhibit the immune system's ability to detect and destroy cancer cells.

Associations between physical activity, brain health, cognitive function, and circulating GPLD1 in healthy older (65-85 years) individuals.

Declines in physical and cognitive function are common in older adults. The circulating enzyme glycosylphosphatidylinositol (GPI)-specific phospholipase D1 (GPLD1) is elevated after exercise and has been associated with improved cognitive function when administered to aged mice. The purpose of this study was to investigate the relationship between GPLD1 and both cognitive function and brain structure/function in older adults with either high or low levels of physical activity.

Higher physical activity levels are related to faecal microbiota diversity and composition in young adults.

Increasing physical activity (PA) is recognised as an efficacious approach for preventing and treating cardiometabolic diseases. Recently, the composition of microorganisms living within the gut has been proposed as an important appropriate target for treating these diseases. Whether PA is related to faecal microbiota diversity and composition in humans remains to be ascertained.

Effects of linear versus curvilinear sprint training on multidirectional speed in young soccer players: a randomized parallel-group trial.

The purpose of this study was to examine the effects of linear sprint training (LST) compared to curvilinear sprint training (CST) using an equivalent session training volume, on linear (LS) and curvilinear (CS) sprint performance, horizontal force-velocity profile, and change of direction (COD) ability in young soccer players. In a randomized pre-post parallel-group trial design, nineteen U16 male soccer players were randomly assigned to LST (n = 9) and CST (n = 10) groups. Both groups performed 11 sprint training sessions over 6 weeks.

RETRAGAM: Resistance training based on gamification during physical education. Rationale and study protocol.

Children's physical inactivity and increasing sedentary behaviour have become major public health concerns, with a concurrent decline in muscular fitness (MF) contributing to poor physical outcomes during childhood and adolescence, highlighting the importance of developing resistance training (RT) programs. Furthermore, several educational strategies such as gamification seem to increase students' motivation which can produce an increase in performance outcomes. This study describes the rationale and protocol of a school-based randomized controlled trial called "RETRAGAM" (REsistance TRAining based on GAMification).

Uterus didelphys: the first case report on molecular profiling of endometrial tissue from both uterine cavities.

Background: A didelphic uterus represents a unique and infrequent congenital condition in which a woman possesses two distinct uteri, each with its own cervix. This anomaly arises due to partial or incomplete merging of the Müllerian ducts during the developmental stages in the womb. Accounting for uterine malformations, a didelphic uterus is a relatively rare condition, affecting approximately 0.

Introduction: Dupilumab is an IL-4 / IL-13 inhibitor monoclonal antibody approved for the treatment of moderate-to-severe atopic dermatitis (AD) with remarkable safety and efficacy profiles. However, former studies have reported an increase in serum eosinophils during treatment, with undetermined clinical significance.

The Objective: of this study is to evaluate changes in blood eosinophils and other laboratory parameters while on dupilumab.

Multi-generational exposure of Daphnia magna to pharmaceuticals: Effects on colonization, reproduction, and habitat selection behavior.

The presence of pharmaceuticals in the aquatic environment is increasing due to their growing use for human health. Although most studies are based on short exposures to these contaminants, the present study has emerged from the need to study pharmaceuticals in aquatic organisms over a long-term exposure to understand any multi-generational chronic effects and alterations regarding habitat selection. Therefore, this study shows: (1) the ability of Daphnia magna to colonize environments contaminated with caffeine, ibuprofen and fluoxetine, and (2) the effect of these pharmaceuticals on reproduction and habitat selection (under two scenarios: with and without food) after a long-term exposure period of three generations.
