Unculturable and non sporulating fungi represent a great challenge in studying biotrophic ,endotrophic mycorrhizal fungal groups. In this study novel culture dependent technique complemented with PCR was used to detect identify of unculturable soil . To develop techniques for cultivation the purpose expanding studies on biodiversity , Soil Infusion Agar (SIA) developed By technique, from higher...
The facile preparation of conformal polydopamine (PDA) films on broad classes of materials has prompted extensive research into a wide variety of potential applications for PDA. The constituent molecular species in PDA exhibit diverse chemical moieties, and therefore highly variable properties of PDA-based devices may evolve with post-processing conditions. Here we report the use of redox-inact...
In this study, the polydopamine (PDA) film was coated on polished 316Lss and then thermally treated at 150 °C (labeled as PDA-Th150), and the stability of coatings was also investigated. Straining test indicated that PDA-Th150 coating performed better in affording sufficient adherence to 316 L SS substrate. Moreover, both PDA and PDA-Th150 coating suffered slight swelling during immersion in de...
We study the most important probabilistic computation modes for pushdown automata. First we show that deterministic pushdown automata (pda) are weaker than Las Vegas pda, which in turn are weaker than one-sided-error pda. Next one-sidederror pda are shown to be weaker than (nondeterministic) pda. Finally bounded error two-sided error pda and nondeterministic pda are incomparable. To show the li...
Patent ductus arteriosus (PDA) is the most common congenital heart disease in dogs and usually causes heart failure and death unless corrected at a young age. Previous histologic studies in a line of dogs derived from Miniature Poodles with hereditary PDA identified varying degrees of hypoplasia and asymmetry of ductus-specific smooth muscle and the presence of aortalike elastic tissue in the d...
BACKGROUND The optimal treatment regimen or protocol for managing a persistent patent ductus arteriosus (PDA) in extremely low birth weight (ELBW) infants has not been well established. This study was aimed at evaluating the failure rate of a cyclooxygenase (COX) inhibitor (COI) for PDA closure and to determine the incidence of a PDA requiring ligation in ELBW infants. We examined the clinical ...
The aggressiveness of pancreatic ductal adenocarcinoma (PDA) is characterized by its high metastatic potential and lack of effective therapies, which is the result of a lack of understanding of the mechanisms involved in promoting PDA metastases. We identified Annexin A2 (ANXA2), a member of the Annexin family of calcium-dependent phospholipid binding proteins, as a new molecule that promotes P...
Sénizergues has proved that language equivalence is decidable for disjoint ǫ-deterministic PDA. Stirling has showed that strong bisimilarity is decidable for PDA. On the negative side Srba demonstrated that the weak bisimilarity is undecidable for normed PDA. Later Jančar and Srba established the undecidability of the weak bisimilarity for disjoint ǫ-pushing PDA and disjoint ǫ-popping PDA. Thes...
در این پژوهش منشاء خزندگان را مورد بررسی قرار داده، خانواده های سوسماران را در ایران معرفی نموده و ویژگی های آنها را ذکر کرده ایم، خانواده lacertidae را از منظر فیلوژنی، رده بندی و همچنین جنس های آن را، مرور کرده ایم. جنس lacerta که هدف اصلی پژوهش حاضر است در ایران دارای دو گونه می باشد؛ یکی گونه ی lantz & cyrén, 1920 lacerta media که از این گونه، تنها زیرگونه ی lacerta media media lantz & cy...
زمینه و هدف: روشهای مختلفی جهت بستن مجرای شریانی باز (pda ) وجود دارد . در این مطالعه نتایج درمانی، عوارض و هزینه بستن pda به روش غیرجراحی (با استفاده از coil) با روش جراحی مقایسه شده است.روش کار: کلیه بیمارانی که در سال 1384 ، pda آنها به روش جراحی و غیر جراحی در مرکز آموزشی درمانی شهید مدنی بسته شده بود انتخاب شده و از پرونده بالینی آنها اطلاعات مورد نظر استخراج گردید. تمام بیماران تا 6 ماه پ...
