In recent years, the availability of automatically generated spatial information of various kinds has developed dramatically. Nowadays, virtually any kind of information is obtainable via the web. Route descriptions of diverse kinds can be obtained from many different sources and across different modalities. Views of maps and geographic information can be accessed in various ways, and local spa...

Background The piwi family genes are highly conserved during evolution and play a crucial role in stem cell self-renewal, gametogenesis, and RNA interference in diverse organisms ranging from Arabidopsis to humans. Piwil2, also known as Hili, is one of the four human homologues of piwi. Piwil2 was found in germ cells of adult testis, suggesting that this gene functions in spermatogonial stem ce...

Background: The SALL4/Sall4 is constitutively expressed in human and mice. SALL4 mRNA could be used as a marker for the diagnosis of different types of cancers. On the other hand, chrysin has diverse biological properties. Objectives: In the present study, the effect of the chrysin was investigated on the CT26 colon cancer in vitro and in vivo. Furthermore, the expression levels of the stem cel...

A sequential chemical fractionation was applied to a compost, with its dissolved organic matter (DOM) extracted in water and separated in hydrophilic (HiDOM) and hydrophobic (HoDOM) components and a water extract, following oxidation of compost suspension with an oxygen flux (TEA). The components sequentially isolated by mild extractions and hydrolyses as structurally unbound (SU), weakly bound...

objective: micrornas (mirnas) are noncoding rnas that function as key regulators of diverse biological activities such as cellular metabolism, cell proliferation and cell cycle regulation. recent studies have indicated the high potential of these small molecules to control stem cell differentiation into desired cells. the aim of present study is to investigate the possible effect of let-7f on e...

background: our preliminary data on the protein expression of sort1 in ovarian carcinoma tissues showed that sortilin was overexpressed in ovarian carcinoma patients and cell lines, while non-malignant ovaries expressed comparably lower amount of this protein. in spite of diverse ligands and also different putative functions of sortilin (ntr3), the function of overexpressed sortilin in ovarian ...

Introduction: Sialic acid plays pivotal roles in various critical physiological events at molecular and cellular levels and also pathological processes. Changes in sialic acid concentration are observed in many pathological processes; for example, there are some available data on the evaluated level of sialic acid and neurodegenerative prevalence. It can be proposed that sialic acid can play a ...

Background In vitro culturing and retransplantion of vitrified- warmed ovarian tissue are two ways to restore fertility after radiation or chemotherapy.This study aimed to evaluate the incidence of apoptosis in vitrified human ovarian tissue after warming, long term culturing and xenotransplantation by morphological analyses and apoptosis genes expression evaluation. MaterialsAndMethods We obta...
