retinoblastoma is the most common intraocular tumor in children resulting from genetic alterations and transformation of mature retinal cells. the objective of this study was to investigate the effects of sd-208, tgf-β-ri kinase inhibitor, on the expression of some mirnas including a mir-17/92 cluster in retinoblastoma cells. prior to initiate this work, the cell proliferation was studied by me...

Conventional data envelopment analysis (DEA) methods assume that input and output variables are continuous. However, in many real managerial cases, some inputs and/or outputs can only take integer values. Simply rounding the performance targets to the nearest integers can lead to misleading solutions and efficiency evaluation. Addressing this kind of integer-valued data, the current paper propo...

We present a new architecture of layered space-time codes as a combination of BLAST architecture and of special STTC codes which are variations about the codes first introduced by Jafarkhani et al. and named Super Orthogonal Space-Time Trellis Codes (SOSTTC). Using powerful set partitioning, these codes are able to combine the coding advantage of STTC’s together with the advantage diversity of ...

Abstract In a decision-making process, one finds that there are alternatives which can be categorized into several groups, based on his or her perspectives, and/or on expected outcome, such as whether his or her choice brings about gains or losses, or that such a choice is right or wrong. Besides, there are many cases with a dilemma where it is hard to select the best choice through transitive ...

AIM The growing enthusiasm to perform laparoscopic sleeve gastrectomy (LSG) in morbidly obese patients exposes also the complications associated with this type of surgery. LSG is not only performed in super-super-obese patients, but in addition has also its standing as a procedure in patients with multiple intraabdominal adhesions based on prior surgeries or after failed gastric banding. Howeve...

For the past twenty years, protein tertiary structure research has been given much attention, with solutions existing for both wet lab procedures (x-ray crystallography and NMR spectroscopy) and bioinformatics approaches (threading, homology-modeling, and de novo). Unfortunately, each approach has significant shortcomings, such as necessary time, capital, expertise (for wet lab procedures) or r...
