Resolving the mystery of Cyanerpes (Thraupidae) ‘black eggs’, with notes on the breeding and exaggerated displays of Hypocnemoides antbirds (Thamnophilidae)

Between the end of the nineteenth and the middle of the twentieth centuries intermittent reports of ‘black eggs’ belonging to one or more species of Passeriformes in South America were usually attributed to small-bodied tanagers of the genera Cyanerpes and Chlorophanes. Doubts co...

Crystallographic and Spectroscopic Evidence of High-Pressure Phase Transition of l -Histidine Methyl Ester Dihydrochloride

Abstract We investigate the dependence of the structural and vibrational properties of l-histidine methyl ester dihydrochloride (LHMED) on high-pressure conditions in the range of 0.0–8.2 GPa. Combining single-crystal X-ray diffraction (SCXRD) and Raman spectroscopy, we found a r...

Intensifying compound drought–heatwave events weaken ecosystem water-use efficiency in the Nile River Basin

Climate warming has intensified compound drought–heatwave (CDHW) events worldwide, posing growing threats to ecosystem carbon–water dynamics. However, the impacts of CDHWs on ecosystem water-use efficiency (WUE), particularly event sequencing, drought memory, and climatic heterog...

Successful Combined Therapy for Post-Orgasmic Illness Syndrome: A Case Report.

Post-Orgasmic Illness Syndrome (POIS) is a rare con-dition characterized by flu-like symptoms after ejacula-tion, lasting several days and impairing quality of life. A 62-year-old man developed POIS after percutaneous ep-ididymal sperm aspiration, with symptoms lasting seven days...

Resistant Candida spp. in Healthy Individuals: Mapping a Surveillance Blind Spot

The prevalence and characteristics of resistant, biofilm-forming Candida strains in healthy individuals remain poorly understood. In this work, Candida strains from 23 healthy volunteers and 11 candidiasis patients (n = 34) were isolated and characterized. Biofilm formation capac...

Sleep duration and compliance with sleep recommendations among Brazilian children and adolescents: an updated systematic review and meta-analysis

OBJECTIVE: To update the evidence on sleep duration among children and adolescents, provide pooled estimates of mean sleep duration and compliance with sleep recommendations, and examine whether differences in measurement methods, assessment instruments, and guideline criteria co...

Lean management in a low-digitalization context: implementing manual time and motion analysis in a public hospital emergency department

Purpose This study aims to describe the challenges and adaptive strategies involved in implementing a manual chronoanalysis instrument at the entrance of a medium-sized public emergency department in a nondigital context, from a Lean in Emergency Care perspective. Design/methodol...

Hydrogel-based strategies for the controlled delivery of analgesic and anti-inflammatory drugs

Abstract In clinical practice, drug encapsulation is an important strategy for enhancing therapeutic efficacy and reducing adverse effects. This review critically examines how polymer origin, crosslinking strategy, swelling behavior, degradation rate, and three-dimensional networ...

Testicular Echobiometry and Sperm Characterization in Oncilla ( Leopardus tigrinus ) From the Caatinga Biome

ABSTRACT Among neotropical small felids, the Leopardus tigrinus is classified as vulnerable by the International Union for Conservation of Nature, but studies on reproductive morphology and physiology are scarce for conservation strategies. This study aimed to describe testicular...

Molecular insights and ADMET profiling of iridoids as candidate leads for erectile dysfunction therapy

Abstract Context Erectile dysfunction (ED) significantly affects male psychosocial health and has an increasing incidence. Although phosphodiesterase 5 (PDEi-5) inhibitors are the first-line therapy, the occurrence of visual side effects resulting from cross-inhibition of the PDE...

Modified Citrus Pectin-Mediated Gal-3 Reduction Attenuates Metabolic Dysfunction-Associated Steatohepatitis in an Experimental Model

Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by hepatic steatosis, inflammation, fibrosis, and metabolic dysfunction, with limited therapeutic options currently available. This study investigated whether pharmacological inhibition of Galectin-3 (Gal-3)...

Multi-Target Analysis of Xanthone Derivatives as Potential Anti-Trypanosoma cruzi Agents: An Integrated Computational Screening

Chagas disease, caused by the parasite Trypanosoma cruzi , affects approximately 8 million people worldwide. The search for new therapeutic candidates is intensified by the limited efficacy and severe adverse effects of current treatments, such as benznidazole and nifurtimox. In...

A transformer-based framework for device-free human activity recognition using Wi-Fi CSI

Abstract Human activity recognition (HAR) plays a pivotal role in ambient assisted living, particularly for monitoring the elderly and patients with chronic conditions. However, traditional approaches relying on wearable sensors or video cameras face significant challenges regard...

Effect of Combined Pelvic Floor and Inspiratory Muscle Training in Women with Stress Urinary Incontinence Associated with Chronic Obstructive Pulmonary Disease: Study Protocol for a Randomized Controlled Trial

Abstract Chronic Obstructive Pulmonary Disease (COPD) is associated with respiratory muscle weakness and chronic cough, increasing intra-abdominal pressure and contributing to the development of stress urinary incontinence (SUI) in women. Although pelvic floor muscle training (PF...
