A new species of Leporinus Agassiz is described from the rio Curuá, a tributary of the rio Iriri, rio Xingu basin, Serra do Cachimbo, Pará State, Brazil. The new species is diagnosed by the color pattern, which consists of eight to ten midlateral round dark blotches plus 20 to 40 smaller ones scattered over the body, dental formula 3/4, subinferior to inferior mouth, 37 to 38 lateral line scale...

Cyclic terpenes and terpenoids are found throughout nature. They comprise an especially important class of compounds from plants that mediate plant- environment interactions, and they serve as pharmaceutical agents with antimicrobial and anti-tumor activities. Molecular comparisons of several terpene cyclases, the key enzymes responsible for the multistep cyclization of C10, C15, and C20 allyli...

T he events narrated by Shakespeare in his tragedy Hamlet 1 are the following: King Hamlet of Denmark dies suddenly and his brother Claudius a few weeks later marries the widow, his sister-in-law, Queen Gertrude; according to the official explanation, a snakebite was the cause of his death. The ghost of the king appears before his son, Prince Hamlet, and tells him that his own brother, now his ...

Background and Objective: Recent studies have shown that anticholinergic alkaloids compounds have strong analgesic effects. Due to presence of anticholinergic alkaloids in Hyoscyamus niger and its mentioned effects in Iranian traditional medicine, its analgesic effects were assessed. At first, acute and chronic pain thresholds in male NMRI rats with formalin test was evaluated, then oral and in...

A phytochemical study was conducted on the leaves of Phyllanthus reticulatus obtained from a riverside in Taman Negara Kuala Koh, Kelantan. The separations of the chemical components were carried out using different chromatographic techniques and structures of compounds were elucidated by spectroscopic methods including nuclear magnetic resonance as well as mass spectrometry. Three compounds we...

INTRODUCTION Despite the increased rates of infestations with I. ricinus (Ir) and D. reticulatus (Dr) ticks observed over the last decade, no effective control methods have been developed so far. The present study was focused on assessment of the action of pyrethroids on these both tick species. MATERIALS AND METHOD The different doses of four pyrethroids, i.e. deltamethrin - D (K-Othrine), p...

Estimates of the average distances by which marine larvae disperse are generally poorly described, despite the central role that larval dispersal plays in the demographic connectivity of populations across geographic space. Here, we describe the population genetic structure and average dispersal distance of the netted dog whelk Nassarius reticulatus (L.) (Mollusca, Gastropoda, Prosobranchia), a...

We investigated the effects of temperature and relative humidity on population growth and development of the psocid Lepinotus reticulatus Enderlein. Part of this study assessed the effects of marking psocids by using methylene blue, chalk powder, and fluorescent powder to differentiate nymphal stages during development. We found that marking psocids by using methylene blue increased mortality a...
