4. Towards the micropropagation of Euphorbia cyathophora Murray: a wild plant species with medicinal and ornamental potential
RESUMO: Euphorbia cyathophora Murray é uma espécie vegetal com potencial medicinal e ornamental, mas cuja propagação in vitro é desconhecida. Dois experimentos foram realizados para conhecer 1) o efeito da luz (WL) a 25±2 °C e 20 μmol m-2 s-1 intensidade luminosa, ou escuridão a 20±2 °C, nos primeiros 20 dias e posterior colocação em luz (DKL)

5. Gender-specific risk factors for gout: a systematic review of cohort studies
Abstract Background: Though gout is more prevalent in men than women, it remains unclear whether gender influences risk factors for incident gout. We aimed to systematically review all cohort studies examining risk factors for the development of gout by gender. Methods: MEDLINE, EMBASE, CINAHL and the Cochrane Library were searched from inception to March

6. Characterisation of iunH gene knockout strain from Mycobacterium tuberculosis
BACKGROUND Tuberculosis (TB) is an infectious disease caused mainly by the bacillus Mycobacterium tuberculosis. The better understanding of important metabolic pathways from M. tuberculosis can contribute to the development of novel therapeutic and prophylactic strategies to combat TB. Nucleoside hydrolase (MtIAGU-NH), encoded by iunH gene (Rv3393), is an

7. Chronic tophaceous gout in patients with psoriasis
Abstract: Psoriasis is a chronic inflammatory disease of multifactorial etiology influenced by genetic, immunological, and environmental factors. We report the case of a patient with psoriasis for more than 25 years who developed hyperuricemia and chronic tophaceous gout with unusual appearance. In psoriasis, hyperuricemia may occur by increased epidermal ce

8. Effects of purine nucleotide administration on purine nucleotide metabolism in brains of heroin-dependent rats
ABSTRACT Heroin is known to enhance catabolism and inhibit anabolism of purine nucleotides, leading to purine nucleotide deficiencies in rat brains. Here, we determined the effect of exogenous purine nucleotide administration on purine nucleotide metabolism in the brains of heroin-dependent rats. Heroin was administrated in increasing doses for 9 consecutive

9. Assessment of Genetic Fidelity of in vitro Raised Plants in Swertia chirayita through ISSR, RAPD analysis and Peroxidase Profiling during Organogenesis
ABSTRACT An efficient in vitro regeneration protocol for medicinally important herb Swertia chirayita was developed and the genetic fidelity was assessed using RAPD and ISSR markers. The best shoot regeneration was observed on MS basal supplemented with 1.0 mg/L Benzyl amino purine (BAP) in combination with Indole-3-acetic acid (IAA) (0.5 mg/L) that resulted

10. Pyrimidine alkaloids from Eudistoma vannamei
Abstract Methanolic extracts of the Brazilian endemic ascidian Eudistoma vannamei have been extensively studied for their cytotoxic activity against several human cancer cell lines. Previous work reported the occurrence of purine derivatives and staurosporine alkaloids as the major nitrogen-containing compounds. In this study, we report the occurrence of thr

11. Adenosine: an endogenous mediator in the pathogenesis of psoriasis
Abstract: It is known that inflammatory and immune responses protect us from the invasion of micro-organisms and eliminate "wastes" from the injured sites, but they may also be responsible for significant tissue damage. Adenosine, as a purine nucleoside, which is produced in inflamed or injured sites, fulfills its role in limiting tissue damage. Although, it

12. Modulatory effect of iron chelators on adenosine deaminase activity and gene expression in Trichomonas vaginalis
Trichomonas vaginalis is a flagellate protozoan that parasitises the urogenital human tract and causes trichomoniasis. During the infection, the acquisition of nutrients, such as iron and purine and pyrimidine nucleosides, is essential for the survival of the parasite. The enzymes for purinergic signalling, including adenosine deaminase (ADA), which degrades
