Drug use Risks in Portuguese Rural vs Urban Environments: Harm Reduction Challenges in a Progressive Drug Policy Setting.

Portugal is commonly recognized as one of the best drug policy examples in the world. Nonetheless, contrasts between drug use risks in rural vs urban settings in the country is an understudied topic, even if its specific challenges are commonly affirmed, both by professionals and people who use drugs (PWUD). The aim of this study was to compare rural and urban environments concerning socio-sanitary services availability; illegal drugs availability; risk behaviors related to drug use; stigma associated with illicit drug use; and social support.

Allostery and Evolution: A Molecular Journey Through the Structural and Dynamical Landscape of an Enzyme Super Family.

Allosteric regulation is a powerful mechanism for controlling the efficiency of enzymes. Deciphering the evolutionary mechanisms by which allosteric properties have been acquired in enzymes is of fundamental importance. We used the malate (MalDH) and lactate deydrogenases (LDHs) superfamily as model to elucidate this phenomenon.

Chitosan/γ-PGA nanoparticles and IFN-γ immunotherapy: A dual approach for triple-negative breast cancer treatment.

Interferon-γ (IFN-γ) is a key mediator in antitumor immunity and immunotherapy responses, yet its clinical application remains restricted to chronic granulomatous disease and malignant osteopetrosis. IFN-γ effectiveness as a standalone treatment has shown limited success in clinical trials and its potential for synergistic effects when combined with immunotherapies is under clinical exploration. A particularly compelling combination is that of IFN-γ with Toll-like receptor (TLR) agonists that holds significant promise for cancer treatment.

Mycodiversity in a micro-habitat: twelve species, including four new taxa, isolated from uredinia of coffee leaf rust, .

During surveys in the centres of origin of the coffee leaf rust (CLR), in Africa, as well as in its exotic range in Brazil, 23 isolates of the genus were obtained from uredinial pustules. Using a phylogenetic analysis of all isolates involving a combination of partial sequences of the internal transcribed spacer region of rDNA (ITS) and two gene regions: actin ( and translation elongation factor-1α (), 12 species were delimited; including four new species - , , and . GCPSR criteria were employed for species recognition, supported by morphological and cultural characters.

New species of Ellipsomyxa (Bivalvulida: Ceratomyxidae) parasitizing the gallbladder of Ageneiosus ucayalensis (Siluriformes: Auchenipteridae) in the Brazilian Amazon region.

The present study describes a new myxozoan species, Ellipsomyxa matosi n. sp. infecting the gallbladder of the catfish Ageneiosus ucayalensis, on Jutuba Island, municipality of Belém, state of Pará, Brazil.
