We conducted a snow depth 0 cm (non-snowpack), 10 cm, 20 cm, 30 cm and natural depth) gradient experiment under four quantities of nitrogen addition (control, no added N; low-N, 5 g N m(-2) yr(-1); medium-N, 10 g N m(-2) yr(-1); and high-N, 15 g N m(-2) yr(-1)) and took an-entire-year measurements of soil respiration (Rs) in Korean pine forests in northeastern China during 2013-2014. No evidenc...
BACKGROUNDS The effects of acute blood volume expansion (BVE) on the respiratory mechanics of normal animals have been not extensively studied. The subject is of both theoretical and practical interest since BVE is a frequent medical intervention, and the associated increase in cardiac output may occur in different physiopathological situations. OBJECTIVES To describe the changes in the param...
Human identification (ID) is a biometric task, comparing single input sample to many stored templates to identify an individual in a reference database. This paper aims to present the perspectives of personalized heartbeat pattern for reliable ECG-based identification. The investigations are using a database with 460 pairs of 12-lead resting electrocardiograms (ECG) with 10-s durations recorded...
A Bax-dependent increase of reactive oxygen species (ROS) and other reactive species (RS) occurs after withdrawing NGF from mouse sympathetic neurons in cell culture. Possible mechanisms underlying the increased ROS/RS are leakage of electrons from the mitochondrial electron transport chain secondary to caspase cleavage of respiratory complexes or leakage secondary to depletion of cytochrome c ...
The immunophenotype of Reed-Sternberg (RS) cells in Hodgkin's disease (HD) has not been clearly defined, partly owing to difficulties in studying RS cells in cell suspensions or identifying them with certainty in frozen sections. We studied the immunophenotype of RS cells with a recently developed plastic section immunohistochemical technique on acetone-fixed tissues that affords superior morph...
Richter syndrome (RS) represents the development of diffuse large B-cell lymphoma in the context of chronic lymphocytic leukemia. The scarcity of biologic information about RS has hampered the identification of molecular predictors of RS outcome. We addressed this issue by performing a comprehensive molecular characterization of 86 pathologically proven RS. TP53 disruption (47.1%) and c-MYC abn...
منطقه معدنی بزوشک به وسعت 30 کیلومترمربع در 63 کیلومتری جنوب غربی مشهد، در زون بینالود قرار دارد. زمین شناسی منطقه شامل اسلیت ( سری مایان) و سنگ آهک و دولومیت است. این منطقه اکتشافی به دو بخش بزوشک (1) در جنوب غرب روستای بزوشک، و بزوشک (2) در شمال شرق آن تقسیم می شود. کانی سازی در این منطقه به شکل رگه ای می باشد. در منطقه بزوشک (1) کانی سازی مس- طلا با امتداد تقریباً شمالی – جنوبی در راستای زون ...
چکیده افزایش فعالیت های کشاورزی توام با تولید آلاینده ها یکی از مشکلات جدی و در حال گسترش پیش روی انسان عصر حاضر است. در میان آلاینده های کشاورزی فلزات سنگین به دلیل غیر قابل تجزیه بودن و اثرات فیزیولوژیکی که بر موجودات زنده در غلظت های کم دارند، از اهمیت خاصی برخوردارند. این عناصر به دلیل تحرک کم به مرور در خاک انباشته می شوند. انباشت این عناصر در خاک در نهایت باعث ورود آنها به چرخه غذایی و ت...
Richter syndrome (RS) derives from the rare transformation of chronic lymphocytic leukemia (CLL) into an aggressive lymphoma, most commonly of the diffuse large B cell lymphoma (DLBCL) type. The molecular pathogenesis of RS is only partially understood. By combining whole-exome sequencing and copy-number analysis of 9 CLL-RS pairs and of an extended panel of 43 RS cases, we show that this aggre...
Multinucleated Reed-Sternberg (RS) cells are pathognomonic for classical Hodgkin lymphoma (HL), and their presence is essential for diagnosis. How these giant tumor cells develop is controversial, however. It has been postulated that RS cells arise from mononucleated Hodgkin cells via endomitosis. Conversely, continuous single-cell tracking of HL cell lines by long-term time-lapse microscopy ha...
