The distribution and abundance of mosquito larvae in a freshwater marsh were determined during a low water period in the late summer. Culex tarsalis larval abundance was significantly associated with the percent cover by Typha spp. root masses and Typha spp. stem density in 1-m2 quadrants. Larval mosquito abundance was not significantly related to bulrush (Scirpus californicus) stem density, po...

A new species of Heredius Marsh, 2002 is described from Brazil. H. flavus n. sp. differs from the other known Heredius species by its yellow mesosoma and metasoma, acinose-carinate face, acinose temple, malar space length about 0.56 times eye height, ocello-ocular distance about 4.0 times diameter of the lateral ocellus; acinose-rugose mesoscutal lobes, sternaulus finely scrobiculate and almost...

BACKGROUND Gentamicin (GM) is used as antibiotic for Gram-negative infections, but its administration is limited due to a side-effect of nephrotoxicity. It was attempted to investigate the effect of Althaea officinalis flower extract (AOFE) against nephrotoxicity induced by GM in male rats. METHODS 30-year-old male Wistar rats were divided into five groups. Group 1 as a negative control group...

Variable selection is an essential part of any statistical analysis and yet has been somewhat neglected in the context of longitudinal data analysis. In this article, we propose a generalized version of Mallows's C(p) (GC(p)) suitable for use with both parametric and nonparametric models. GC(p) provides an estimate of a measure of model's adequacy for prediction. We examine its performance with...

Althaea rosea (Linn.) is a medicinal plant from China and Korea that has been traditionally used to control inflammation, to stop bedwetting and as a mouthwash in cases of bleeding gums. Its flowers are employed medicinally for their emollient, demulcent and diuretic properties, which make them useful in chest complaints. Furthermore, a flower extract decoction is used to improve blood circulat...

The in vitro antibacterial activities of 29 traditional medicinal plants used in respiratory ailments were assessed on multidrug resistant Gram-positive and Gram-negative bacteria isolated from the sore throat patients and two reference strains. The methanolic, n-hexane, and aqueous extracts were screened by the agar well diffusion assay. Bioactive fractions of effective extracts were identifie...
