The ability of two species of tits to remember the location and/or features of an object was tested in a delayed-matching-to-sample procedure. Three values of retention interval between presentation of the sample stimulus and the choice--30 sec, 5 min, and 15 min--were used. Both species performed at above-chance level at all retention intervals, and there was no significant decline in accuracy...

OBJECTIVE There has been a growing interest in finding plants with biological active ingredients for medicinal application. MATERIALS AND METHODS Three colors of petals of Althaea officinalis (A. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. RESULTS The reddish pink flowers of A. officinalis have more antioxidan...

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...

OBJECTIVES Wound is defined simply as the disruption of the biochemical, cellular, and anatomic continuity of a tissue. Plants and their extracts known as phytomedicine have immense potential for the management and treatment of wounds. MATERIALS AND METHODS Due to the undesirable side effects, in the control and treatment of the wound infections, it is recommended to use natural materials suc...

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...

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...
