Objetivo do presente trabalho foi descrever morfo-anatomicamente os frutos, sementes e o desenvolvimento pós-seminal de quiabo (Abelmoschus sculentus (L.) Moench. – cv. “Santa Cruz 47”). Os frutos as foram caracterizados quanto à forma, coloração, textura, tipo, consistência, deiscência dimensões. Para anatomia das sementes, utilizadas a microscopia óptica eletrônica varredura. De acordo com re...

The whole plant aqueous extract of E. littorale was tested for its hypoglycemic activity on normoglycemic, hyperglycemic and alloxan induced diabetic rats. Blood sugar lowering activity was not observed in normoglycemic and glucose loaded hyperglycemic rats in the short time experiment. But in case of diabetic rats, the fall of blood sugar after 30 days treatment with the aqueous extract was fo...

BIES: Dr Mayr, I’d like to begin with several questions about your history and the history of ideas in evolutionary biology, then focus on some questions about specific issues in evolutionary biology and, finally, conclude with a discussion of some matters in the philosophy of science and of biology in particular. Let’s begin with the matters of history. This year is the 60 anniversary of publi...

In the postgenomic era, a new strategy for chemical dereplication of polyketide anti-infective drugs requires novel genomics and chromatographic strategies. An endosymbiotic fungal strain CLB38 was isolated from the root tissue of Combretum latifolium Blume (Combretaceae) which was collected from the Western Ghats of India. The isolate CLB38 was then identified as Emericella variecolor by its c...

The common wild fig, Ficus thonningii, is extensively used in African ethnomedicine for treating a number of disease conditions which include diarrhoea, urinary tract infections, diabetes mellitus, gonorrhoea, respiratory infections, and mental illnesses. This review aims to present a logical analysis of the nutritional, phytochemical and pharmacological properties of F. thonningii in relation ...

The present investigation was undertaken to standardize and study the dose-dependent effect of three weeks treatment with hot and cold aqueous extract of E. littorale (0.5, 1 and 2 g/kg, po) on streptozotocin (STZ) induced type I diabetic (confirmed by histopathology) rats (45 mg/kg, iv single dose). Treatment of rats with STZ produced cardinal signs of diabetes-mellitus like a significant loss...

At present, all available diagnostic antibody detection tests for Trypanosoma brucei gambiense human African trypanosomiasis are based on predominant variant surface glycoproteins (VSGs), such as VSG LiTat 1.5. During investigations aiming at replacement of the native VSGs by recombinant proteins or synthetic peptides, the sequence of VSG LiTat 1.5 was derived from cDNA and direct N-termin...

Species-specific probes against cytoplasmic rRNA and nuclear rDNA of Heterosigma akashiwo were designed on the basis of LSU and ITS sequences. FISH protocols for whole cell and nuclear were established to detect this alga. The results showed that the rRNA-targeted probe hybridized with cytoplasmic rRNA, showing strong green fluorescence throughout the whole cell, while cells labeled by rDNA-tar...
