پراکنش جغرافیایی تیره باقلائیان (به جزء جنس گون) تجزیه و تحلیل گردیده تا با داشتن چشم اندازی از الگوی پراکنش این خانواده بتوانیم تصمیمات حفاظتی بهتری داشته باشیم. به این منظور از ١٠٤٩٨ گزارش ثبت شده ی ژئورفرنس شده از ایران استفاده گردید. با استفاده از نرم افزار diva-gis و arcview و خانه های 1° x 1° عرض/طول جغرافیایی، غنای گونه ای، گونه های انحصاری، weighted endemism، corrected weighted endemism...
We present an interdisciplinary approach that, by incorporating a range of experimental and computational techniques, allows the identification and characterization of functional/immunogenic domains. This approach has been applied to ArtJ, an arginine-binding protein whose orthologs in Chlamydiae trachomatis (CT ArtJ) and pneumoniae (CPn ArtJ) are shown to have different immunogenic properties ...
background and objectives: infection with vancomycin-resistant enterococci (vre) has caused a therapeutic problem. vana and vanb resistant types are the predominant phenotypes among vancomycin resistant enetrococci. transposon 1546 (tn1546) harboring the vana gene cluster, plays an important role in the horizontal transfer of vana gene. in this study, we examined the phenotypic and genotypic di...
abstract geopedology is a systematic approach of geomorphic analysis for soil mapping which focuses the field operation mainly on sample area. the purpose of this study is to determine the credibility of generalization of the results of geopedological approach for similar landforms in the borujen region, using diversity and similarity indices in a soil taxonomic hierarchical structure. after a ...
Long-range migrations and the resulting admixtures between populations have been important forces shaping human genetic diversity. Most existing methods for detecting and reconstructing historical admixture events are based on allele frequency divergences or patterns of ancestry segments in chromosomes of admixed individuals. An emerging new approach harnesses the exponential decay of admixture...
The vp7 genes of 194 strains of group A rotaviruses representing all known G types were analyzed with three restriction enzymes by direct digestion of amplified cDNA copies or by deduction of the restriction patterns from known sequences. Mammalian rotavirus strains were classified into 28 restriction patterns consisting of combinations of the 6 profiles (s1 to s6) obtained by digestion with Sa...
