13. O território e as implicações da violência urbana no processo de trabalho dos agentes comunitários de saúde em uma unidade básica
Resumo No contexto da atenção primária à saúde, a violência urbana é um desafio que tem impactado diretamente o setor por conta da localização geográfica dos equipamentos de saúde em áreas de vulnerabilidade e da maior interação dos trabalhadores com situações que colocam em perigo, implícita ou explicitamente, sua segurança. O artigo discu

14. Pharmacological characterization of cnidarian extracts from the Caribbean Sea: evaluation of anti-snake venom and antitumor properties
Abstract Background: Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities. This study aimed to evaluate toxicological activities and potential as antitumor and antiophidic agents contained in total extracts from fi

15. Pre-clinical interaction of ayahuasca, a brew used in spiritual movements, with morphine and propofol
ABSTRACT Ayahuasca is a beverage with psychoactive properties used in religious and ceremonial rituals by some religious groups. The main active components of ayahuasca are dimethyltryptamine and the harmala alkaloids with β-carboline structure acting as monoamine oxidase A inhibitors. This combination produces a pronounced activation of serotonergic pathwa

16. Design, Synthesis, Biological Evaluation and Molecular Modeling Studies of Novel Eugenol Esters as Leishmanicidal Agents
Leishmaniasis is a neglected pathology with a high incidence worldwide, and is a governmental health issue due to the increased morbidity and mortality associated with the disease and a scarce therapeutic arsenal. Cysteine proteases have been investigated as targets for new drugs because they are essential in the infectivity of the parasite during its intera

17. Omniscience and Semantic Information
ABSTRACT First, I consider a few motivations to idealize epistemic logics1 in such a degree that brings up the problem of logical omniscience [LOP]. I argue that the main motivation to hold omniscience is of a philosophical-scientific2 background (Stalnaker 1991), in the sense philosophers have a not so peculiar way of investigating underlying mechanisms, i.

18. Fractographic and rheological characterizations of CF/PP-PE-copolymer composites tested in tensile
Abstract This work shows the fractographic study of fractured surfaces resulted from tensile tests of thermoplastic composites based on poly(propylene-co-ethylene) (PP-PE) and modified PP-PE copolymers reinforced with continuous carbon fibers (CF). The PP-PE matrix was modified with two agents called AM1 (based on maleic anhydride) and AM2 (containing an ela

19. Evaluation of basil extract ( Ocimum basilicum L.) on oxidative, anti-genotoxic and anti-inflammatory effects in human leukocytes cell cultures exposed to challenging agents
ABSTRACT Ocimum is one of the most important genera of the Lamiaceae family. Several studies about basil and its popular use reveal many characteristics of the herb, including its use as antioxidant, anti-aging, anti-inflammatory, anti-carcinogenic, anti-microbial, and cardiovascular agents, among others. In this paper, we evaluated genotoxic, oxidative, and

20. Inhibition of cytochrome P450 3A enzyme by Millettia aboensis: its effect on the pharmacokinetic properties of efavirenz and nevirapine
ABSTRACT The chronic and comorbid nature of HIV infection necessitate the use of multiple drugs including herbs to relieve symptoms with a possible increase in herb–drug interaction cases. This study was designed to evaluate the effect of Millettia aboensis (Hook. f.) Baker, Fabaceae, on cytochrome P450 3A isoenzyme and the influence of this effect on the

21. Antifungal activities of tacrolimus in combination with antifungal agents against fluconazole-susceptible and fluconazole-resistant Trichosporon asahii isolates
ABSTRACT The antifungal activity of tacrolimus in combination with antifungal agents against different fungal species has been previously reported. Here we report the in vitro interactions between tacrolimus and amphotericin B, fluconazole, itraconazole, and caspofungin against 30 clinical isolates of both fluconazole-susceptible and fluconazole-resistant Tr

22. Distribution of Xanthene Dyes in DPPC Vesicles: Rationally Accounting for Drug Partitioning Using a Membrane Model
The correct selection of a dye that has effective action as a photosensitizer is a primary concern for successful therapeutic outcomes. The effectiveness of the photodynamic agent is related to both the targeting of cell membranes and the photochemical yield of the chosen dye. The distributions of xanthene derivatives Eosin Y, Erythrosin B, and Rose Bengal B

23. Influence of nucleating agent on the crystallization kinetics and morphology of polypropylene
Abstract The influence of three nucleating agents from different generations on the crystallization behavior of propylene homopolymer was studied by differential scanning calorimetry (DSC) and atomic force microscopy (AFM). The amount of nucleating agent used varied between 1000 and 2200 ppm. The new generation nucleating agent, Hyperform® HPN-68L, accelera

24. Effects of the encapsulation of usnic acid into liposomes and interactions with antituberculous agents against multidrug-resistant tuberculosis clinical isolates
Mycobacterium tuberculosis (Mtb) has acquired resistance and consequently the antibiotic therapeutic options available against this microorganism are limited. In this scenario, the use of usnic acid (UA), a natural compound, encapsulated into liposomes is proposed as a new approach in multidrug-resistant tuberculosis (MDR-TB) therapy. Thus the aim of this st
