Abstract Endophytic fungi isolated from the red seaweed Bostrychia radicans were studied to identify their molecularly diverse and biologically active natural chemical products. According to 28S ribosomal DNA-based identification, the strain named C81 was 98% identical to Phomopsis longicolla . This strain was cultivated in solid rice medium and produced three major metabolites identified as 18-deoxycytochalasin H ( 1 ), mycophenolic acid ( 2 ), and dicerandrol C ( 3 ). The chemical structures of these compounds ...

Abstract Crude extracts of Rutales species were tested in vitro against the trypomastigote form of Trypanosoma cruzi at 4 mg/mL, and 20% of them showed significant activity (80%). Their inhibitory activity against the glycolytic enzyme GAPDH from T. cruzi has also been evaluated at the concentrations of 100 and 200 mg/mL. Additionally, the inhibitory activity of 13 purified coumarins were also assayed against T. cruzi-GAPDH. Chalepin was the most active substance with IC50 = 64 mM. The 3D structure ...

Two endemic lycophyte species Isoetes cangae and Isoetes serracarajensis have been recently described in the State of Pará in the Amazon forest located in northern Brazil. Isoetes L. has survived through three mass extinctions. Plants are considered small-sized, heterosporous, and can display a great diversity of physiological adaptations to different environments. Thus, the current study aimed to estimate the genetic variation of the populations of I. cangae and I. serracarajensis to generate information ...

An evaluation of the results of the Brazilian experience in colorectal laparoscopic procedures in a multicenter prospective protocol done by the Brazilian Society of Colo-Proctology is presented. From December 1991 to August 1998, 1,161 patients (583 men and 578 women; mean age, 49.8 years), were operated on laparoscopically. Most of the procedures (40.5%) were for cancer, and the most common procedure was anterior resection (22.5%). The mean operative time was 189 minutes (3.1 hours). There were 42 ( ...

The structure of the glycosomal glyceraldehyde‐3‐phosphate dehydrogenase (gGAPDH) from Trypanosoma cruzi complexed with chalepin, a natural product from Pilocarpus spicatus , has been determined by X‐ray crystallography to 1.95 Å resolution. The structure is in the apo form without cofactors in the subunits of the tetrameric gGAPDH in the asymmetric unit. Unequivocal density corresponding to the inhibitor was clearly identified in one monomer. The final refined model of the complex shows extensive ...

A cicatrização e remodelação do cólon resultam das modificações do colágeno na matriz extracelular. Algumas condições desequilibram sua renovação, enfraquecendo a resistência mecânica a cicatriz, como resultado da atividade elevada das metaloproteinases locais, e levando a um alto risco de deiscência. As metaloproteinases da matriz extracelular (matrix metalloproteinases, MMPs) constituem uma família de endopeptidases zinco-dependentes - metzincinas. São reconhecidos atualmente, em humanos, cerca de ...

Abstract BACKGROUND Sertraline ( SER ) is a widely used antidepressant persistent in sewage treatment plant ( STP ) effluents. Zero‐valent iron ( ZVI ) has been studied for degradation of organic contaminants. However, it usually results in poor mineralization efficiency. The effect of H 2 O 2 on ZVI mediated degradation of SER was studied and compared with sole ZVI and the homogeneous Fenton process. RESULTS The effect of ZVI dose on SER degradation was different with 20 and 200 mesh particle sizes. The degradation ...

The zero-valent iron (ZVI) mediated degradation of the antibiotic ciprofloxacin (CIP) was studied under oxic condition. Operational parameters such as ZVI concentration and initial pH value were evaluated. Increase of the ZVI concentration from 1 to 5gL(-1) resulted in a sharp increase of the observed pseudo-first order rate constant of CIP degradation, reaching a plateau at around 10 g L(-1). The contribution of adsorption to the overall removal of CIP and dissolved organic carbon (DOC) was evaluated ...
