We were interested in the elucidation of the interaction between the heparan sulfate proteoglycan, perlecan, and PTEN in the regulation of vascular smooth muscle cell (SMC) growth. We verified serum-stimulated DNA synthesis, and Akt and FAK phosphorylation were significantly reduced in SMCs overexpressing wild-type PTEN. Our previous studies showed perlecan is a potent inhibitor of serum-stimul...
Smooth muscle cell (SMC) differentiation and dedifferentiation play a critical role in the pathogenesis of cardiovascular diseases. The lack of a good and simple in vitro SMC differentiation system has hampered the progress of SMC field for years. The generation of such an in vitro system would be invaluable for exploring molecular mechanisms of SMC differentiation and dedifferentiation. Recent...
Platelet-derived growth factor (PDGF)-BB is a well-known smooth muscle (SM) cell (SMC) phenotypic modulator that signals by binding to PDGF alphaalpha-, alphabeta-, and betabeta-membrane receptors. PDGF-DD is a recently identified PDGF family member, and its role in SMC phenotypic modulation is unknown. Here we demonstrate that PDGF-DD inhibited expression of multiple SMC genes, including SM al...
The structural maintenance of chromosome (Smc) protein is highly conserved and involved in chromosome compaction, cohesion, and other DNA-related processes. In Bacillus subtilis, smc null mutations cause defects in DNA supercoiling, chromosome compaction, and chromosome partitioning. We investigated the effects of smc mutations on global gene expression in B. subtilis using DNA microarrays. We ...
In the following paper, we provide a review and development of sequential Monte Carlo (SMC) methods ([17, 18, 24]) for option pricing. SMC are a class of Monte Carlo-based algorithms, that are designed to approximate expectations w.r.t a sequence of related probability measures. These approaches have been used, successfully, for a wide class of applications in engineering, statistics and physic...
Prevalence of subjective memory complaints (SMC) in elderly community dwellers (ECD) ranges from 25 to 50%. Some controversy exists over the association between SMC and cognitive status. Objective We investigated whether a correlation in cognitive performance existed between two different groups according to SMC. Methods The Mini Mental State Examination (MMSE) and Dementia Rating Scale-Mat...
مقدمه : در ایران، توسعه صنعت پرورش قارچ خوراکی مورد توجه قرار گرفته و میزان تولید آن به نود هزارتن در سال رسیده است. با تولید هرکیلوگرم قارچ خوراکی دکمه ای، حدود پنج کیلوگرم پسماند بر جای می ماند که با استفاده از تکنولوژی ورمی کمپوست می توان ضمن تصفیه این پسماندها آن را به کود آلی با ارزشی تبدیل نموده و میزان استفاده کودهای شیمیایی را کاهش داده و در جهت توسعه پایدار گام برداشت.هدف این مطالعه تب...
In this paper, a robust tracking control method for automatic take-off and trajectory tracking of a quadrotor helicopter is presented. The designed controller includes two parts: a position controller and an attitude controller. The attitude controller is designed by using the sliding mode control (SMC) method to track the desired pitch and roll angles, which are the output of position controll...
BACKGROUND It is recommended that children aged 3 months to five years of age living in areas of seasonal transmission in the sub-Sahel should receive Seasonal Malaria Chemoprevention (SMC) with sulfadoxine-pyrimethamine plus amodiaquine (SPAQ) during the malaria transmission season. The purpose of this study was to evaluate the safety of SMC with SPAQ in children when delivered by community he...
Integrin-associated protein (IAP/CD47) augments the function of alpha2beta1 integrin in smooth muscle cells (SMC), resulting in enhanced chemotaxis toward soluble collagen (Wang, X-Q., and W.A. Frazier. 1998. Mol. Biol. Cell. 9:865). IAP-deficient SMC derived from IAP(-/-) animals did not migrate in response to 4N1K (KRFYVVMWKK), a peptide agonist of IAP derived from the COOH-terminal domain of...
