introduction: diagnosis, prediction and control of oral lesions is usually done classically based on clinical signs and histopathologic features. due to lack of timely diagnosis in all conventional methods or differential diagnosis, biopsy of patient is needed. therefore, the patient might be irritated. so, an intelligent method for quick and accurate diagnosis would be crucial. intelligent sys...

Introduction: The cell cycle network is responsible of control, growth and proliferation of cells. The relationship between the cell cycle network and cancer emergence, and the complex reciprocal interactions between genes/proteins calls for computational models to analyze this regulatory network. Ample experimental data confirm the existence of random behaviors in the interactions between gene...

the microphase separation of hydrated perfluorinated sulfonic acid membrane nafion was investigated using dissipative particle dynamics (dpd). the nafion as a polymer was modelled by connecting coarse grained beads which corresponds to the hydrophobic backbone of polytetrafluoroethylene and perfluorinated side chains terminated by hydrophilic end particles of sulfonic acid groups [1, 2]. each f...

background: it is now well-demonstrated that histone demethylases play an important role in developmental controls, cell-fate decisions, and a variety of diseases such as cancer. lysine-specific demethylase 5d (kdm5d) is a male-specific histone demethylase that specifically demethylates di- and tri-methyl h3k4 at the start site of active genes. in this light, the aim of this study was to invest...

تحقیقات مختلف اثبات نموده اند که رشد و محتوای بیوشیمیایی روتیفرها می تواند تحت تاثیر نوع غذا و غلظت مواد غذایی تغییر نماید. ریز جلبک ها به عنوان یکی از منابع غذایی مهم برای کشت روتیفرها به ویژه از لحاظ شاخص های نظیر رشد، بقا، میزان پروتئین، چربی و اسیدهای چرب، ضروری می باشند. لذا تحقیق حاضر جهت مقایسه جلبک خشک (کلرلای پودری) و جلبک های تازه (ایزوکرایسیس گالبانا و نانوکلروپسیس آکولاتا) بر رشد، ت...

Embryogenesis, regeneration and cell differentiation in microbiological entities are influenced by mechanical forces. Therefore, development of mechanical properties of these materials is important. Neural network technique is a useful method which can be used to obtain cell deformation by the means of force-geometric deformation data or vice versa. Prior to insertion in the needle injection pr...

In this paper‎, ‎a bidirectional ring network with three cells and different time delays is presented‎. ‎To propose this model which is a good extension of three-unit neural networks‎, ‎coupled cell network theory and neural network theory are applied‎. ‎In this model‎, ‎every cell has self-connections without delay but different time delays are assumed in other connections‎. ‎A suitable Lyapun...
