Purpose: Keratoconus presents certain peculiarities in pediatric patients when compared with adults. The greatest challenge in children is that the disease is more severe and faster in progression. In this retrospective study, we aimed to compare the accelerated and Dresden protocols for corneal crosslinking in patients aged <18 years who were followed-up for at least 12 months.

Modern agriculture faces the challenge of increasing production without expanding cultivated areas, promoting sustainable practices that ensure food security and environmental preservation. Integrated crop-livestock systems (ICLSs) stand out as an effective strategy, diversifying and intensifying agricultural production in a sustainable manner, ensuring adequate soil cover, and improving nutrient cycling efficiency. Thus, this study aimed to explore and compare integrated crop-livestock systems with Zuri guinea grass ( cv.

Article Synopsis
  • CeO samples were made using the polymeric precursor method with varying calcination temperatures, leading to changes in particle size and shape.
  • Advanced techniques like positron annihilation lifetime spectroscopy (PALS) and electron paramagnetic resonance (EPR) revealed the presence of different types of oxygen vacancies associated with various cerium ions.
  • Impedance spectroscopy showed that as the calcination temperature increased, there was a reduction in electrical conductance and the formation of polarons in the material.

Tree growth and longevity trade-offs fundamentally shape the terrestrial carbon balance. Yet, we lack a unified understanding of how such trade-offs vary across the world's forests. By mapping life history traits for a wide range of species across the Americas, we reveal considerable variation in life expectancies from 10 centimeters in diameter (ranging from 1.

We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover. Our analyses are based on 2023 forest inventory plots (1 ha) that provide abundance data for a total of 5188 tree species. Within-plot species composition reflected both local environmental conditions (especially soil nutrients and hydrology) and geographical regions.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are severe complications that can occur in infections caused by any species. Due to the high lethality rate and the lack of specific treatment for ALI/ARDS, studies aimed at understanding and searching for treatment strategies for such complications have been fundamental. Here, we investigated the protective role of dietary supplementation with DHA-rich fish oil against lung damage induced by ANKA in a murine model.

This study developed and evaluated chitosan-sodium alginate capsules containing the probiotic Lacticaseibacillus rhamnosus GG using extrusion and emulsification techniques. The encapsulated L. rhamnosus GG cells were also evaluated for technological and probiotic-related physiological functionalities, as well as when incorporated in UHT and powdered milk.

Purpose: To characterize the extracellular vesicle protein cargo in the aqueous humor and plasma of patients with ocular toxoplasmosis.

Methods: Aqueous humor and plasma were collected from six patients with active ocular toxoplasmosis and six patients with cataract. Extracellular vesicles were isolated, and western blotting and mass spectrometry were performed for protein analysis.

Ocular syphilis is a re-emerging inflammatory eye disease with a clear gender imbalance, disproportionately affecting men. We investigated the impact of gender on the presentation, management practices and clinical outcomes of this condition. Data generated from a study of patients consecutively diagnosed with ocular syphilis who attended a subspecialist uveitis service at one of four hospitals in Brazil over a 30-month period were disaggregated for analysis by gender.

Purpose: To demonstrate that the presence of active retinochoroiditis in eyes with previous hyperpigmented old retinochoroidal lesions is not exclusive of ocular toxoplasmosis.

Methods: A case series was constructed by reviewing medical records.

Results: Four Brazilian patients presenting active posterior uveitis in eyes with previous hyperpigmented old retinochoroidal lesions were identified.

Introduction: This paper explores the role of Brazilian research institutions in the global and national context of study of medicinal plants. Most of these plants have ethnopharmacological use and herbal medicines related to the Amazon. It highlights Brazil's position in scientific production and the importance of Amazonian resources in developing phytomedicines.

Hydroxychloroquine (HCQ) is a safe antimalarial drug but its overdosage or inappropriate use, such as during the pandemic, may cause adverse effects once this drug is considered a potent inhibitor of autophagy. Information about HCQ's effects on the reproductive field, including gametes and initial embryos, is limited. In this study, we evaluated the effect of HCQ (1, 6, 12, and 24 μM) on pre-implantation embryo development, autophagy, and apoptosis of bovine embryos produced in vitro.

Caffeine is present in a large number of beverages and is an additive used in dietary supplements. Therefore, the concern about its quality and safety for consumers has been increasing and hence requires faster and simpler analytical methods to determine the caffeine amount. The high-throughput analysis is an appropriate solution to pharmaceuticals, bioanalysis, forensic and food laboratory routines.

Article Synopsis
  • A 2019 outbreak of acute toxoplasmosis in São Paulo, Brazil, involved 83 individuals and was associated with rapid onset symptoms likely due to oocyst contamination from vegetables.
  • Serological testing revealed a significant spike (73%) in positive IgM toxoplasmosis cases in 2019 compared to the previous year, with at least 4.8% of patients developing serious eye conditions.
  • The study underscores the importance of improving food and water hygiene practices to prevent future outbreaks and highlights the need for better awareness and diagnosis efforts.

Trees structure the Earth's most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge.

Background: Trust in government is associated with health behaviours and is an important consideration in population health interventions. While there is a reported decline in public trust in government across OECD countries, the tools used to measure trust are limited in their use for informing action to (re)build trust, and have limitations related to reliability and validity. To address the limitations of existing measures available to track public trust, the aim of the present work was to develop a new measure of trust in government.
