Çalışmada halkın mutfak eşyası, sepet, nazarlık, süpürge, oyuncak vb. çeşitli yararlandığı belirlenerek bu bitkilerin kullanım şekilleri ortaya konmuştur. Çalışma; merkez ve merkeze bağlı 8 ilçe ile ilçelerdeki 30 yerleşim biriminde gerçekleştirilmiştir. A...
Abstract Background Pollen‐food allergy syndrome (PFAS) is caused by the cross‐reaction of specific IgE to pollen allergens with similar contained in fruits, vegetable, and nuts. The representative allergen responsible for this pathogenesis‐related protein (PR)‐10. Specific test using Gly m 4, soybean PR‐10, widely used diagnose soy allergy. We aimed investigate whether 4‐specific useful predic...
Plant allergies are a frequent cause of visits to the allergologist. In the Alergologica 2005 study carried out in Spain, fruits were the main cause of food allergies [1]. Plant allergies in a specific population are related to consumption habits and to the pollen pattern of the region under study. The objective of this retrospective study was to determine the proteins responsible for fruit all...
این پژوهش با هدف تعیین تأثیر جادههای جنگلی درجه سه بر فلور، شکل زیستی و پراکنش جغرافیایی پوشش گیاهی تیپ ممرز-راش در جنگل خیرود نوشهر انجام شد. 36 خطنمونه به طول 100 متر (در هر دامنه خاکریزی و خاکبرداری 18 خطنمونه) از حاشیة جاده تا درون جنگل انتخاب و در طول هر خطنمونه، هشت قطعهنمونه به ابعاد 2×1 متر در فواصل صفر متری (حاشیة جاده)، پنج، 10، 15، 20، 30، 45 و 100 متری برداشت شدند. فاصلة اث...
Betula pendula Roth. یکی از گونههای مهم خانواده Betulaceae در ایران به علت رویشگاه طبیعی محدود و عدم زادآوری در معرض خطر انقراض میباشد. استفاده از تکنیک کشت بافت گیاهی راه حلی مناسب برای تکثیر غیرجنسی این گونه و همچنین حفاظت و حمایت آن در شرایط کنترل شدهاست. در این پژوهش کالزایی B. pendula با استفاده از پنج ریزنمونه (برگ، ساقه، تکگره، دمبرگ و پوست) در دو محیط کشت WPM و NT با دو ترکیب هورمون...
Biological particles suspended in the atmosphere have a crucial role dynamics of biosphere underneath. Although much attention is paid for chemical and physical properties these particles, their biological taxonomic identity, which relevant ecological research, remains little studied. We took air samples at 300 meters above forest central Amazonia, seven periods 7 days, used high-throughput DNA...
CONTEXT Betula pendula Roth (Betulaceae) exhibits many pharmacological activities in humans including anticancer, antibacterial, and antiviral effects. However, the antioxidant activity of BP towards lipid degradation has not been fully determined. OBJECTIVE The BP ethanol and methanol extracts were evaluated to determine antioxidant activity by an in vitro method and lyophilized extract of B...
Sterile fungi isolated from surface-sterilized roots of the Ericaceae, and hypothesized to be conspecific based primarily on restriction fragment length polymorphisms, were provisionally named as Variable White Taxon (VWT). In preliminary resynthesis trials with Vaccinium myrtilloides or V. vitis-idaea, isolates did not form typical ericoid mycorrhizas. Additional isolates obtained from roots o...
