this paper addresses a nonlinear observer based control scheme to synchronize chaotic systems subject to uncertainties and external disturbances. it is assumed that the dynamic of slave system is not completely known. in order to compensate for the system perturbation resulting from parameter variations and mismodeling phenomena, an adaptive neural network observer is employed to handle this pr...

Through observation of the ovaries, the luteal and follicular phases ofeach buffalo were specified. A total number of 36 oviducts at follicular phase and 36 oviducts at luteal phasewere collected and 3 tissue samples were taken from 3 regions of infundib...

Background: Fine needle aspiration (FNA) has led to a decrease in unnecessary surgeries for thyroid nodules. This study was designed to compare diagnostic value of FNA and frozen section methods in the follicular lesions. Methods: This is a cross-sectional study based on the medical records of 42 patients who were referred to surgery clinic of Rasool-e-Akram hospital in Tehran with complain...

Well-differentiated papillary and follicular thyroid carcinomas are the two most common types of thyroid cancer. Although cancerous cells in both types phenotypically resemble the epithelial follicular cell, the tumors display different histological characteristics and clinical outcomes. Molecular defects contributing to the separate development pathways remain largely unclear. We evaluated gen...

Mixed medullary-follicular carcinoma is an uncommon tumor of the thyroid. It is characterized by histological and immunohistochemical features of both follicular and parafollicular C cells. We report two female patients, aged 26 and 78 years, with mixed medullary-follicular carcinoma. Histologically, the tumors are composed of follicular carcinoma areas and solid nests of polygonal cells consis...

Background: To evaluate whether success of fertilization and embryo quality are more probable when follicular fluid Anti-mullerian hormone levels are higher . Materials and Methods: 62 women who underwent IVF cycle were divided into fertilized oocytes group (n=42) and non- fertilized oocytes group (n=20) . Follicular fluid Anti-mullerian hormone levels were measured in both groups. Results: Ant...

Abstract Background Follicular lymphoma (FL) is the second most common adnexal lymphoma of the eye that almost all of them are reported in elderly patients. Primary FL of the eye has been reported in only two children. Pediatric FL appears to be biologically distinct from typical adult FL. In cases without other organ involvement excision alone with close monitoring is a treatment of choic...

It rare and under-recognized manifestation that associated with typically aggressive clinical course. Cases feature predominantly follicular or perifollicular growth pattern exhibit strong consistent expression T-folli...
