Structural inequality linked to brain volume and network dynamics in aging and dementia across the Americas.

Structural inequality, the uneven distribution of resources and opportunities, influences health outcomes. However, the biological embedding of structural inequality in aging and dementia, especially among underrepresented populations, is unclear. We examined the association between structural inequality (country-level and state-level Gini indices) and brain volume and connectivity in 2,135 healthy controls, and individuals with Alzheimer's disease and frontotemporal lobe degeneration from Latin America and the United States.

Two new species and a new record of Hypoxylaceae (Xylariales, Ascomycota) from Mexico.

The family Hypoxylaceae has a cosmopolitan distribution with greater diversity in tropical regions, its growth habit is saprotrophic, endophytic and potentially phytopathogenic. From the revision of herbarium specimens and field collections from the Yucatan Peninsula, two new species were described: , characterized by having fusiform spores and which is distinguished by having stromata vinaceous and dark brown KOH-extractable pigments. The species are described based on morphological characters and Bayesian Inference analyses of four molecular markers (ITS, LSU, RPB2 and TUB2).

Application of Natural Zeolite as Catalyst in the Degradation of the Azo Dye DO39 by Plasma.

The discharge of industrial wastewater with dyes into natural tributaries has serious environmental consequences on aquatic ecosystems and the health of living beings. Atmospheric plasmas have proven to be very useful for the degradation of organic contaminants in water; in this context, corona type discharge, owing to its physical characteristics, is capable of degrading and even mineralizing dyes dissolved in water. In this work, zeolite was used as a catalyst in the degradation of the textile azo dye Direct Orange 39 (DO39) through interaction with plasma generated at atmospheric pressure.

Beyond the imaging evaluation of fractures of the lateral process of the talus: Let's not forget concomitant injuries.

Fractures of the lateral process of the talus (FLPT) are uncommon fractures that represent a clinical challenge. Traditional radiological classification systems rely predominantly on radiographic findings. However, due to the high rate of FLPT misdiagnosis and the limited accuracy in evaluating concomitant talar injuries through plain radiographs, novel imaging classification systems have been developed that aim to enhance the diagnosis of concomitant talar injuries, thereby optimizing patient management and reducing the incidence of long-term complications.

CONSTANS alters the circadian clock in Arabidopsis thaliana.

Plants are sessile organisms that have acquired highly plastic developmental strategies to adapt to the environment. Among these processes, the floral transition is essential to ensure reproductive success and is finely regulated by several internal and external genetic networks. The photoperiodic pathway, which controls plant response to day length, is one of the most important pathways controlling flowering.

Racial Bias in Pediatric Pain Perception.

Racial disparities in pediatric pain care are prevalent across a variety of health care settings, and likely contribute to broader disparities in health, morbidity, and mortality. The present research expands on prior work demonstrating potential perceptual contributions to pain care disparities in adults and tests whether racial bias in pain perception extends to child targets. We examined the perception and hypothetical treatment of pain in Black and White boys (experiment 1), Black and White boys and girls (experiment 2), Black and White boys and adult men (experiment 3), and Black, White, Asian, and Latinx boys (experiment 4).

The impact of elder abuse training on subacute health providers and older adults: study protocol for a randomized control trial.

Background: Elder abuse often goes unreported and undetected. Older people may be ashamed, fearful, or otherwise reticent to disclose abuse, and many health providers are not confident in asking about it. In the No More Shame study, we will evaluate a co-designed, multi-component intervention that aims to improve health providers' recognition, response, and referral of elder abuse.
