Pretreatment knowledge of crestal and radicular dentoalveolar zones and their associated thicknesses can improve risk assessment to meet esthetic and functional goals, particularly when discrepancies in anterior maxillary and mandibular arches exist and when an anterior protected articulation is to be achieved. This paper discusses a new classification of dentoalveolar bone phenotypes that diff...

It is widely recognized that protected areas can strongly influence ecological systems and that hybridization is an important conservation issue. However, previous studies have not explicitly considered the influence of protected areas on hybridization dynamics. Eastern wolves are a species of special concern and their distribution is largely restricted to a protected population in Algonquin Pr...

in recent decades, necessity to protect environment has been a serious concern for all people and international communities. in appropriate development of human economic activities, subsistence dependence of the growing world population on nature decreases the natural diversity of ecosystems and habitats day by day and provides additional constraints for life and survival of wildlife. as a resu...

in this study, a medicinal plant, galla rhois (gr), was examined and screened for its anti-helicobacter pylori activity. galla rhois was extracted with 70% ethanol. inhibitory zone tests, as in vitro assays, and an in vivo study using a mongolian gerbil (meriones unguiculatus) model were performed. the safety of the gr extract was then evaluated in an animal study. the galla rhois extract demon...
