forest reserves are one of the most important approaches in ecosystem management in iran. in order to determine the effects of reserve management on plants diversity (woody plants and ground flora) in three zones (core zone, buffer zone, and transmission zone of chamhesar pear forest reserve), we mapped land form units. then 18 main sampling units (20×50=1000 m2) distributed randomly were chose...
in order to investigate antioxidant and antimicrobial effects of pomegranate peel powder (ppp), this research was conducted as completely randomized design arranged in a 2 × 2 factorial experiment using pomegranate peel powder (0 and 2 percent) and soybean oil (so, zero and six percent in growing period; zero and eight percent in finishing period). one hundred and sixty 11-day-old ross 308 broi...
jurassic deposits are well exposed in the bazehowz area, south west of mashhad city, east alborz, iran. it contains plant macrofossilsbelonging to eighteen species of eleven genera of various orders such as equisetales, filicales, bennettitales, cycadales,corystospermales, caytoniales, ginkgoales and pinales. two biozones were recognized in the type section of bazehowz formation.biozone i is an...
In October 2012, in a survey in order to study the flora of paddy fields and aquatic ecosystems of Gilan province (N Iran), we encountered an unknown species in “Aynak lagoon” in southeast of Rasht, covered surface of about 12 ha pond densely. Comparing the flora of pond with previous years or adjacent ponds showed that, the new weed was dominant in interference with natural flora of aquatic ec...
Microbial ecology and dysbiosis are topics worthy of study. This review article will be the first of a two-part series that will discuss normal flora and threats to its ecology resulting in dysbiosis. Microorganisms are generally required to attain critical population increases before they threaten the host. The research on the role of bacterial microorganisms which are considered to be part of...
In a recent publication, we reported the identification and characterization of two distinct phenotypes in SpragueDawley rats obtained from the Charles River Raleigh facility (Robosky et al., 2005). The phenotypes were designated as HIP (high hippuric acid level in urine) and CA (high chlorogenic acid metabolites level in urine). The endogenous urinary metabolic profile of each phenotype was di...
BACKGROUND Bacterial vaginosis (BV) - a syndrome characterised by a shift in vaginal flora - appears to be particularly common in sub-Saharan Africa, but little is known of the pattern of vaginal flora associated with BV in Africa. We conducted a study aimed at determining the prevalence of BV and patterns of BV-associated vaginal micro-flora among women with vaginal discharge syndrome (VDS) in...
We examined the distribution of ground-flora species (herbaceous and woody species <1 m tall) across riparian areas of northeastern Wisconsin in an effort to understand how hierarchical landscape properties, such as the physiographic system (ground moraine and outwash plain), valley system (constrained and unconstrained), and valley floor landforms influence distribution patterns of ground-flor...
BACKGROUND Identifying modifiable factors that increase women's vulnerability to HIV is a critical step in developing effective female-initiated prevention interventions. The primary objective of this study was to pool individual participant data from prospective longitudinal studies to investigate the association between intravaginal practices and acquisition of HIV infection among women in su...
Germfree rats were used in 3 experiments to study the effects of the microbial flora on survival time after acute uremia produced by a one-stage bilateral nephrectomy. Germfree rats, limited-flora rats, and conventionalized rats (all maintained continuously in isolators) were subjected to nephrectomy or to sham nephrectomy, deprived of food and water until they died, respectively, of uremia or ...
