AIMS To determine if naltrexone affects smoking behaviors in smokers preparing to quit, and whether or not such pre-quit responses predict post-quit date outcomes. DESIGN Double-blind, placebo-controlled, randomized study. The current study focused on smoking-related outcomes in the pre-quit phase, which was 1 week prior to the quit date, and these findings were linked with reductions in the ...

Medicinal plants synthesize various secondary metabolites that can be used for therapeutic and antimicrobial purposes. In Brazil, the Unified Health System (SUS) offers several herbal medicines as an alternative in treatment of diseases. Considering importance these production chemicals expand options improve health SUS users, this review was carried out to quantitatively determine antifungal a...

development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. selection of such plant species are required to combat air pollution based on their tolerance level. present study was undertaken to evaluate the tolerance level of higher plants in east of esfahan city, iran, during 2011 in terms of assessing air pollution tolerance...

palatability includes plants physical and chemical property that encourages an animal selecta plant for grazing. this study is an attempt for intruducing an indicator for determining thepalatability of rangeland plants. to do this, the relationship between palatability and foragequality of rangeland plants in karsanak rangelands of the chaharmahal-va-bakhtiari provincewas studied. first, plant ...

today, environmental crisis and loss of natural resources are the principle causes of the creation of environmental management systems. the optimal management of natural resources requires the assessment and classification of ecological and environmental potentials. using this method, the abilities and restrictions of resources can be recognized, and their future trends can be predicted. nebka ...

Background & Aim: Chaharmahal va Bakhtiari province contains several major floristic plant associations of central Zagros Mountains. Kallar species were used for medicines nutrias in this area. However, these valuable species have been threatened and even become at risk of extinction due to habitat fragmentation and disturbance. Therefore, the first step in protecting theses species is identify...

Rangeland ploughing and cultivation using dry land farming crops may be amajor reason for the destruction of natural resources in the semiarid and sub-humid regionswhich may significantly change the composition and reduce the stability of the affectedcommunities. In present research, an abandoned ploughed site was compared with a nearbyreference site in the semiarid rangelands of Baharkish, Quc...

the mountainous area of fereizi is located in northwestern binalood range, khorassan, north east of iran. special climatic and geographical characteristics of the area make it a suitable habitat for various plant species. as a part of a research poject on the flora and vegetation of binalood mountain range, the floristic composition of this area, life forms and chorology of vascular plants have...

Several projects investigating genetic function and evolution through sequencing and comparison of multiple genomes are now underway. These projects consume many resources, and appropriate planning should be devoted to choosing which species to sequence, potentially involving cooperation among different sequencing centres. A widely discussed criterion for species choice is the maximisation of e...
