introduction: perepubertal varicocele can result in hypotrophy of testes, sperm damage and decrease the function of leydig cells in future. pathophysiology of varicocele is unclear. increased reactive oxygen species (ros) is a major theory. there are many controversies in treatment of pediatric varicocele. flaxseed (fs) is the richest source of lignans with antioxidant properties. the aim of th...

Background: Fine needle aspiration (FNA) is the most important method in the diagnosis of thyroid nodules before surgery. Recently, the efficiency of FNA in thyroid nodule management has been debatable. On the other hand, intraoperative frozen section (FS) has been used to confirm the diagnosis of FNA and select the proper surgical approach. In this regard, the present study aimed to assess the...

this study deals with employing foundry sand (fs) as new low cost iron source in heterogeneousphoto-fenton process for the degradation of herbicide isoproturon (ipu) in aqueous solution. thecharacterization of the fs by eds confirmed presence of iron (23%) required for photo-fenton andsimultaneously confirmed absence of any heavy metals which may be susceptible to leaching. the photo-fenton eff...

Objective(s): Pioglitazone (PGZ), a peroxisome proliferator-activated receptor gamma (PPAR-γ) agonist, has significant neuroprotective effects and has been reported to regulate inflammatory processes.Materials and Methods: We evaluated the effects of PGZ on febrile seizure (FS) in rat pups. Three groups of male rat pups received intraperitoneal (IP) injections of PGZ (5, 10, and 20 mg/kg). Lipo...

In this paper, we introduce the notion of super finitely separating functions which gives a characterization of RB-domains. Then we prove that FS-domains and RB-domains are equivalent in some special cases by the following three claims: a dcpo is an RB-domain if and only if there exists an approximate identity for it consisting of super finitely separating functions; a consistent join-semilatti...

Nowadays, a lot of efforts have been applied to find an appropriate catalyst for generating hydrogen from NaBH4. Hence in the current study, various nanostructures of TiO2 were employed to obtain an insight into how the different support catalysts effect on the hydrolysis rate of NaBH4. For this aim, disordered filaments (DF-NTs) and ordered free-standing TiO2 nanotubes (FS-NTs) were fabricated...

This paper researches two key factors (angle and thickness) of a weak layer in relation to their influencing mechanism on slope stability. It puts forward the sliding surface angle and morphological model criteria for the control of rock slopes and realization of its failure mechanism. By comparing the Failure Modes and Safety Factors (Fs) obtained from numerical analysis, the influence pattern...

The Internet provides easy access to a kind of library resources. However, classification of documents from a large amount of data is still an issue and demands time and energy to find certain documents. Classification of similar documents in specific classes of data can reduce the time for searching the required data, particularly text documents. This is further facilitated by using Artificial...
