This study investigated the impact of catalase (Cat) overexpression in renal proximal tubule cells (RPTCs) on nuclear factor erythroid 2-related factor 2 (Nrf2) stimulation of angiotensinogen (Agt) gene expression and the development of hypertension and renal injury in diabetic Akita transgenic mice. Additionally, adult male mice were treated with the Nrf2 activator oltipraz with or without the...

This is a corrigendum to the article 'Inhibition of Key Digestive Enzymes Related to Diabetes and Hyperlipidemia and Protection of Liver-Kidney Functions by Trigonelline in Diabetic Rats' [Sci Pharm. 2013; 81: 233–246]. Figure 6 is replaced.

A morphogenetically active compound has been isolated from tissue extract of Hydractinia echinata and identified to be N-methylpicolinic acid (homarine). When applied to whole animals, homarine prevents metamorphosis from larval to adult stage and alters the pattern of adult structures. The concentration of homarine in oocytes is about 25 mM. During embryogenesis, metamorphosis and early colony...

The objective of this work was to group different coffee species present in the genebank of the Instituto Agronômico by using some chemical variables. A total of thirty-nine plants belonging to seven species were analyzed for chemical seed components (soluble solids, lipids, trigonelline, chlorogenic acids and caffeine). The results evidenced that species could be grouped by lipids, chlorogenic...

Background: Fenugreek (Trigonella foenum-graecum L.) is an important medicinal plant that is a source of diosgenin, trigonelline and other valuable components. Fenugreek seeds is used for its pharmaceutical and nutraceutical properties. Objective: The aim of present study was to investigate the genetic diversity within and between different populations of Trigonella foenum-graecum using DNA ma...

We studied the metabolic fate of [carbonyl-14C]nicotinamide and [8-(14)C]adenine in segments taken from young and developing leaves, stem, hypocotyls, and roots of a shoot-root type emerging propagule of the mangrove plant Bruguiera gymnorrhiza. Thin-layer chromatography was used together with a bioimaging analyser system. During 4 h of incubation, incorporation of radioactivity from [carbonyl-...

Arabica and Robusta coffee beans were roasted at 220 ± 10°C for 7, 9 and 11 min to identify chemical descriptors in the beverages. The pH of the beverages showed the lowest value in the medium roasting level. In each degree of browning, the soluble solids content remained slightly higher in Arabica drinks. The contents of caffeine did not vary, but trigonelline decreased with burning up intensi...
