background: infection with trichomonas vaginalis is one of the most common sexually transmitted diseases (stds) in humans. the prevalence of infection in iran has been reported between 2 to 8%, depending on deferent socio-cultural conditions. this study aimed to determine the prevalence of t . vaginalis in women referred to gynecologic clinics in hamadan city, west of iran. methods: this descri...

background: trichomoniasis, caused by trichomonas vaginalis , is one of the most common sexually transmitted infections in the world. diagnosis of t. vaginalis is performed by different methods, including wet mount, culture, serological methods and pcr, which required laboratory equipments and expert laboratory personnel. the aim of this study was evaluation of immunochromatographic strip test ...

aggregate stability is an important soil property because it dictates how strongly a soil can resist water erosion. the objectives in this study were: (1) to compare the stability of six soil aggregate size fractions, primarily to determine if aggregate stability varies with aggregate size, and (2) to determine with which aggregate size fraction the stability of most soils would be different fr...

introduction: tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .this paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  materials and methods: sixty re...

Wet age-related macular degeneration (wet AMD), a leading cause of vision loss globally, is a late-onset, multifactorial retinal degenerative disease. The characteristic features of wet AMD are neovascularization originating from the choroidal vasculature and spreading to the subretinal pigment epithelium or subretinal space, and increased intraretinal (IRF) or subretinal fluid (SRF) [1-4]. The...

BACKGROUND AND AIMS Hard-seeded (physical) dormancy is common among plants, yet mechanisms for dormancy release are poorly understood, especially in the tropics. The following questions are asked: (a) whether dormancy release in seed banks of the tropical shrub Parkinsonia aculeata (Caesalpiniaceae) is determined by wet heat (incubation under wet, warm to hot, conditions); and (b) whether its e...

PURPOSE To assess the relative efficacy of three types of controls in reducing respirable silica exposure during artificial stone countertop cutting with a handheld circular saw. APPROACH A handheld worm drive circular saw equipped with a diamond segmented blade was fitted with water supply to wet the blade as is typical. The normal wetted-blade condition was compared to (i) wetted-blade plus...

BACKGROUND Trichomonas vaginalis is a parasitic protozoan which causes most common non viral sexually transmitted disease trichomoniasis. Direct microscopic examination of vaginal fluid remains the most widely used diagnostic test. Although, wet mount examination is the most cost-effective diagnostic test, but it has low sensitivity resulting in under diagnosis of the disease. Therefore, to ove...

A network model of porous media is used to assess the effects of pore structure and matrix wettability on the resistivity of partially saturated rocks. Our focus is the magnitude of the saturation exponent n from Archie’s law and the hysteresis in resistivity between drainage and imbibition cycles. Wettability is found to have the dominant effect on resistivity. The network model is used to inv...

This study analyzed the trends of extreme daily rainfall indices over the Indochina Peninsula from 1960 to 2007. The trends were obtained from high-resolution gridded daily rainfall data compiled by APHRODITE with coordinates of 4°N–25°N and 90E°–112°E. The indices were selected from the list of climate change indices recommended by ETCCDI, which is a joint group of WMO CCl, CLIVAR and JCOMM. T...
