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.

Effects of dynamic resistance training on postexercise hypotension and its mechanisms in hypertensive men.

Background: A possible chronic effect of exercise training is the attenuation of the acute decrease in blood pressure (BP) observed after the execution of a session of exercise [i.e. called postexercise hypotension (PEH)].

Meristematic and meristematic-like fungi in .

Meristematic fungi are mainly defined as having aggregates of thick-walled, melanised cells enlarging and reproducing by isodiametric division. black meristematic and meristematic-like fungi have been allied to , which currently has two accepted families, and , with fungi mainly regarded as pathogens, parasites, saprobes and epiphytes of different plant species. This study aimed to verify the phylogenetic position using four nuclear markers (SSU, LSU, ITS and ) of the genera associated with , namely , , and , and the new genus, .

Effects of tropical fruit blends on fermentative and pigmentation aspects of probiotic native cultured goat milk.

Background: Fruits are sources of bioactive compounds such as phenolics that bring health benefits to consumers. The addition of fruit products and microorganisms with probiotic potential in fermented goat milk can facilitate the acquisition of these benefits through diet. In this sense, the objective of this study was to evaluate the effect of incorporating a mixture of ingredients from jaboticaba (), jambolana (), and mandacaru () fruits on fermentation parameters (pH, titratable acidity, viability of the native culture CNPC003 and the starter culture), associated with pigmentation (phenolic compound content and color) through experimental mixture design.

Electrostatically tuning radical addition and atom abstraction reactions with distonic radical ions.

Although electrostatic catalysis can enhance the kinetics and selectivity of reactions to produce greener synthetic processes, the highly directional nature of electrostatic interactions has limited widespread application. In this study, the influence of oriented electric fields (OEF) on radical addition and atom abstraction reactions are systematically explored with ion-trap mass spectrometry using structurally diverse distonic radical ions that maintain spatially separated charge and radical moieties. When installed on rigid molecular scaffolds, charged functional groups lock the magnitude and orientation of the internal electric field with respect to the radical site, creating an OEF which tunes the reactivity across the set of gas-phase carbon-centred radical reactions.
