Central American and Caribbean consensus for the treatment of MS, NMOSD, and MOGAD.

Background: In recent years, significant progress has been made in immune demyelinating disorders, particularly regarding early diagnosis and disease-modifying drugs (DMDs). Despite advancements, socioeconomic factors in many Latin American countries present unique challenges that impede the proper identification and management of these disorders.

Objectives: The updated consensus from the Central American and Caribbean working group strives to enhance the management of Multiple Sclerosis (MS), Neuromyelitis Optica Spectrum Disorder (NMOSD), and Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD) by offering a framework for incorporating available treatment into clinical practice.

Lessons learned from syndemic HIV research in an immigrant, latinx sexual and gender minority community.

The HIV incidence rate in Miami-Dade County is among the highest in the United States, with Latinx sexual and gender minority (SGM) groups experiencing a disproportionate burden. Despite extensive efforts by both private and public sectors to curb transmission and improve pre-exposure prophylaxis (PrEP) uptake, Latinx SGM groups continue to have high rates of HIV and low PrEP uptake compared to SGM groups overall. Using data collected from a biobehavioral study of the socio-structural factors affecting HIV susceptibility and PrEP uptake among Latinx SGM subgroups in Miami-Dade County, this paper shares lessons learned and provides concrete recommendations for tailoring survey research and biospecimen collection among a largely immigrant, socioeconomically disadvantaged community that is especially vulnerable to HIV.

Stereotactic ablative radiotherapy (SABR) for pelvic nodal oligorecurrence in prostate cancer.

Background: This study evaluated the clinical outcomes of stereotactic ablative radiotherapy (SABR) in the treatment of oligometastatic pelvic node prostate cancer to delay androgen deprivation therapy (ADT).

Materials And Methods: Pelvic lymph node metastases were identified by C-choline positron emission tomography (PET)-computed tomography (CT), and patients were not receiving ADT. SABR was administered using linear accelerators with intensity-modulated and image-guided radiotherapy, at a prescribed dose of 35 Gy in 5 fractions over 2 weeks.

Frugivore Traits Predict Plant-Frugivore Interactions Using Generalized Joint Attribute Modeling.

Under an adaptive hypothesis, the reciprocal influence between mutualistic plants and frugivores is expected to result in suites of matching frugivore and plant traits that structure fruit consumption. Recent work has suggested fruit traits can represent adaptations to broad groups of functionally similar frugivores, but the role of frugivore traits and within-species variation in structuring fruit consumption is less understood. To address these knowledge gaps, we assess the presence of reciprocal trait matching for the mutualistic ecological network comprising of bats that feed on and disperse seeds.

Superstable lipid vacuoles endow cartilage with its shape and biomechanics.

Conventionally, the size, shape, and biomechanics of cartilages are determined by their voluminous extracellular matrix. By contrast, we found that multiple murine cartilages consist of lipid-filled cells called lipochondrocytes. Despite resembling adipocytes, lipochondrocytes were molecularly distinct and produced lipids exclusively through de novo lipogenesis.

Antiplasmodial and Insecticidal Activities of Third-Generation Ivermectin Hybrids.

Preclinical and/or clinical studies have demonstrated the potential of Ivermectin (IVM) for malaria control. In order to improve its antiplasmodial activity and build on previous knowledge, we have designed a third generation of hybrid molecules in which selected pharmacophores were appended to the IVM macrolide, while retaining one or both sugar moieties at the C-13 position. Moreover, we synthesized IVM hybrids that contain structural features of potent IVM metabolites.

Hypovitaminosis D in university workers in Southern Ecuador: interactions between gender and lifestyle.

Background: Hypovitaminosis D may be common in tropical countries and is linked to disorders of phospho-calcium metabolism, rickets, muscle pain, immune system deficiencies, and increased susceptibility to microbial infections.

Objective: To assess the prevalence of hypovitaminosis D in apparently healthy university workers in Loja, Ecuador.

Methods: A cross-sectional study was completed in a private Ecuadorian university from May 2023 to September 2023, involving 440 participants.

Objective: To evaluate the effectiveness of osteopathic manipulative treatment (OMT) associated with transcranial direct current stimulation (tDCS) in reducing pain, disability, and improving quality of life in participants with non-specific chronic low back pain.

Design: A randomised double-blind clinical trial.

Setting: Clinical outpatient unit.

The loss of riparian vegetation along streams causes morphological divergences in functional traits of semiaquatic insects (Heteropteran: Gerromorpha) in the eastern Amazon.

Understanding the effects of mining activities on Amazonian streams and their impact on aquatic communities is of paramount importance in the current context of resource overexploitation in society. In this study, we assessed the significance of the environment and interspecific interactions on the organization patterns of semiaquatic insect species in a mineral extraction region in the eastern Amazon. We utilized the morpho functional characteristics of 22 species from the suborder Gerromorpha (Heteropteran), considering both the abundance and sexual dimorphism of these species.

Two +ssRNA mycoviruses cohabiting the fungal cultivar of leafcutter ants.

Leafcutter ants are dominant herbivores in the Neotropics and rely on a fungus (Leucoagaricus gongylophorus) to transform freshly gathered leaves into a source of nourishment rather than consuming the vegetation directly. Here we report two virus-like particles that were isolated from L. gongylophorus and observed using transmission electron microscopy.

Cutting Edge: Low-dose Recombinant IL-2 Treatment Prevents Autoantibody Responses in Systemic Lupus Erythematosus via Regulatory T Cell-independent Depletion of T Follicular Helper Cells.

The expansion of T follicular helper (Tfh) cells correlates with disease progression in human and murine systemic lupus erythematosus (SLE). Unfortunately, there are no therapies to deplete Tfh cells. Importantly, low-dose rIL-2-based immunotherapy shows potent immunosuppressive effects in SLE patients and lupus-prone mice, primarily attributed to the expansion of regulatory T cells (Tregs).

Machine learning models for temporally precise lapse prediction in alcohol use disorder.

We developed three machine learning models that predict hour-by-hour probabilities of a future lapse back to alcohol use with increasing temporal precision (i.e., lapses in the next week, next day, and next hour).

Innovative Multistage ML-QSAR Models for Malaria: From Data to Discovery.

Malaria presents a significant challenge to global public health, with around 247 million cases estimated to occur annually worldwide. The growing resistance of parasites to existing therapies underscores the urgent need for new and innovative antimalarial drugs. This study leveraged artificial intelligence (AI) to tackle this complex challenge.

Functional microanatomy of the vomeronasal complex of bats.

Recently, Yohe and Krell (The Anatomical Record, vol. 306:2765-2780) lamented the incongruence between genetics and morphology in the vomeronasal system of bats. Here, we studied 105 bat species from 19 families using histology, iodine-enhanced computed tomography (CT), and/or micro-CT.

Effects of Habitat and Fruit Scent on the Interactions between Short-tailed Fruit Bats and Plants.

is a mega-diverse genus of pioneer plants that contributes to the maintenance and regeneration of tropical forests. In the Neotropics, bats use olfaction to forage for fruit and are a main disperser of seeds via consumption and subsequent defecation during flight. In return, fruits provide essential nutrients for year-round.

Gliding toward an understanding of the origin of flight in bats.

Bats are the only mammals capable of powered flight and have correspondingly specialized body plans, particularly in their limb morphology. The origin of bat flight is still not fully understood due to an uninformative fossil record but, from the perspective of a functional transition, it is widely hypothesized that bats evolved from gliding ancestors. Here, we test predictions of the gliding-to-flying hypothesis of the origin of bat flight by using phylogenetic comparative methods to model the evolution of forelimb and hindlimb traits on a dataset spanning four extinct bats and 231 extant mammals with diverse locomotor modes.

Repurposing antiplasmodial leads for cancer: Exploring the antiproliferative effects of N-cinnamoyl-aminoacridines.

Drug repurposing and rescuing have been widely explored as cost-effective approaches to expand the portfolio of chemotherapeutic agents. Based on the reported antitumor properties of both trans-cinnamic acids and quinacrine, an antimalarial aminoacridine, we explored the antiproliferative properties of two series of N-cinnamoyl-aminoacridines recently identified as multi-stage antiplasmodial leads. The compounds were evaluated in vitro against three cancer cell lines (MKN-28, Huh-7, and HepG2), and human primary dermal fibroblasts.

Structure-activity relationship of anticancer and antiplasmodial gold bis(dithiolene) complexes.

Monoanionic gold bis(dithiolene) complexes were recently shown to display activity against ovarian cancer cells, Gram-positive bacteria, strains and the rodent malaria parasite, . To date, only monoanionic gold(III) bis(dithiolene) complexes with a thiazoline backbone substituted with small alkyl chains have been evaluated for biomedical applications. We now analyzed the influence of the length and the hydrophobicity hydrophilicity of these complexes' alkyl chain on their anticancer and antiplasmodial properties.

In this work, we introduce the , a comprehensive and modular command-line interface designed for molecular simulation and microsolvation modeling. The suite interfaces with widely used scientific software, streamlining computational experiments for liquid systems through the automated creation of simulation boxes and topology with adjustable simulation parameters. Furthermore, it has features for graphical and statistical analysis of simulated properties and extraction of trajectory configurations with various filters.

Disclosure of cinnamic acid/4,9-diaminoacridine conjugates as multi-stage antiplasmodial hits.

4,9-diaminoacridines with reported antiplasmodial activity were coupled to different trans-cinnamic acids, delivering a new series of conjugates inspired by the covalent bitherapy concept. The new compounds were more potent than primaquine against hepatic stages of Plasmodium berghei, although this was accompanied by cytotoxic effects on Huh-7 hepatocytes. Relevantly, the conjugates displayed nanomolar activities against blood stage P.

The hierarchical radiation of phyllostomid bats as revealed by adaptive molar morphology.

Adaptive radiations are bursts in biodiversity that generate new evolutionary lineages and phenotypes. However, because they typically occur over millions of years, it is unclear how their macroevolutionary dynamics vary through time and among groups of organisms. Phyllostomid bats radiated extensively for diverse diets-from insects to vertebrates, fruit, nectar, and blood-and we use their molars as a model system to examine the dynamics of adaptive radiations.
