Objective: Correlation of vaginal micro-ecology and human papilloma virus infection to cervical lesions. Methods: From May 2014 to May 2017, 40 patients with cervical lesion enrolled in our hospital were collected and set as the research group. Meanwhile, another 40 patients without the lesion were collected in the control group. Patients in both groups were given determinations of vaginal flor...
In a more and more regulated and socially pressured environment, the durable management of winery effluents must take into account their characteristics and their potential impact on their natural setting. The object of this exploratory study is to establish an inventory of the microbiological composition of winery effluents coming from different treatment systems. We have observed that winery ...
Based on the limited resources available to algal flora in Yazd province in the center of Iran, cultivation, purification and identification of soil algae from seven sites was performed in summer 2013. The soil samples were processed for analysis of Cd, Pb contents. The present paper attempts to analyze survey of soil blue-green algal identification in different types of stations, using morphol...
Ground flora is an important response variable to monitor after tree thinning and prescribed burning treatments de signed to restore Arizona ponderosa pine {Pinusponderosa P.& C. Lawson) forests. This paper reviews published liter ature on the effects of thinning and burning on ground flora in Arizona ponderosa pine forests in five main categories of research: ground flora biomass, species dive...
The first encounter of the neonate with Esch. coli consists of the normal intestinal colonization. Already at this stage the body is able to cope with these micro-organisms, accepting them as a part of the normal intestinal flora, but hindering them from invading the tissues. It is obvious, however, that from this early colonization onward the infant and then the child is carrying a reservoir o...
Lack of knowledge on soil geotechnical properties can cause many problems in the construction and maintenance of irrigation and drainage networks. In general, all of unconventional soils such as gypsiferous soils can cause some problems to irrigation canals. Some studies have been conducted on a variety of problematic soils, but still there is a need for more research activities and field studi...
Magnetic susceptibility (χ) measurements are widely used for the evaluation of soil profile development. Fourteen soil profiles were studied in a relatively wide range of climatic conditions in Fars Province. Citrate-bicarbonate-dithionite (CBD) extraction and micro CT-Scan images were used to evaluate the source of magnetic susceptibility. The results showed that soil samples lost 23 to 91 per...
