Increasing demand for the knowledge about protein-protein interactions (PPIs) is promoting the development of methods for predicting protein interaction network. Although high-throughput technologies have generated considerable PPIs data for various organisms, it has inevitable drawbacks such as high cost, time consumption, and inherently high false positive rate. For this reason, computational...
The hemodynamic response measured by Near Infrared Spectroscopy (NIRS) is temporally delayed from the onset of the underlying neural activity. As a consequence, NIRS based brain-computer-interfaces (BCIs) and neurofeedback learning systems, may have a latency of several seconds in responding to a change in participants' behavioral or mental states, severely limiting the practical use of such sy...
thallium 201 whole body scintigraphy was performed in a 30 year old patient with diffuse osseous metastatic disease secondary to glioblastoma multiforme. multiple sites of thallium uptake correlated with the findings on serial bone scans and radiographs. bone biopsy of a lower lumbar vertebra confirmed that the metastases were of glial origin.
glioblastoma is the most common and the most lethal primary brain cancer. this malignancy is highly locally invasive, rarely metastatic and resistant to current therapies. little is known about the distinct molecular biology of glioblastoma multiforme (gbm) in terms of initiation and progression. so far, several molecular mechanisms have been suggested to implicate in gbm development. homeodoma...
Glioblastoma multiforme is a devastating and intractable type of cancer. Current antineoplastic drugs do not improve the median survival of patients diagnosed with glioblastoma multiforme beyond 14 to 15 months, in part because the blood-brain barrier is generally impermeable to many therapeutic agents. Drugs that target microtubules (MT) have shown remarkable efficacy in a variety of cancers, ...
برهمکنش های بین حلال ها وامواج صوتی موضوعی است که در سالهای اخیر بسیار مورد تحقیق قرار گرفته است. در اولین بخش این مطالعه اثرمولکول های حلال روی سرعت صوت بررسی شد و سپس مدلی تولید شد که قادر به پیش بینی سرعت صوت در حلال خالص و مخلوط حلال ها بود. مدلها با استفاده ازروش ژنتیک الگوریتم و رگرسیون خطی چند متغیر least square support vector machine (ls-svm) وهمچنین (ga-mlr( بدست آمد. در دومین بخش...
برهم کنش های پروتئین-پروتئین در بسیاری از فرآیندهای سلولی نقش مهمی ایفا می کنند. بنابراین شناسایی، پیش بینی و تحلیل برهم کنش های پروتئین-پروتئین در حوزه زیست مولکولی مهم می باشد. روش های آزمایشگاهی که به این منظور طراحی گردیده اند بسیار پرهزینه، پر زحمت و وقت گیر می باشند. به همین دلیل نیاز به روش های محاسباتی برای بررسی برهم کنش های پروتئین-پروتئین روزانه افزایش می یابد. از این رو، هدف اصلی ا...
Glioblastoma multiforme of the cerebellum is rare and comprises a small fraction of all glioblastomas. Eight-five cases have been reported in the literature to date. A 75 year old man is reported with a left cerebellar glioblastoma multiforme. The pathogenesis, course, treatment and prognosis are reviewed.
Constitutive modeling of clay is an important research in geotechnical engineering. It is difficult to use precise mathematical expressions to approximate stress-strain relationship of clay. Artificial neural network (ANN) and support vector machine (SVM) have been successfully used in constitutive modeling of clay. However, generalization ability of ANN has some limitations, and application of...
according to recent developments of predicting methodsin financial markets, and since the stock price is one of the mostimportant factors for investment decision-making, and its predictioncan play an important role in this field, the aim of this study is toprovide a model to predict the stock price movement with highaccuracy. accordingly, a hybrid model for predicting the stock pricemovement us...
