Abstract Comparing reproductive tract morphology between closely-related species may reveal mechanisms and processes leading to isolation cladogenesis. Differences in external are often inconspicuous Neotropical species, tissue samples for DNA sequencing usually scarce fossorial organisms such as amphisbaenians. Therefore, comparing characters of the closely related amphisbaenians be a viable a...

Background: Celery (Apium graveolens) has many therapeutic effects.This plant has many phytoestrogens that can affect on the reproductive endocrine system and can reduce fertility .In this study, hydro alcoholic extracts of celery leaves on the pituitary-gonad axis in young male l mice of Balb/C was investigated. Materials and Methods: The samples were randomly divided into 5 groups (three trea...

The aim of the present study was to evaluate sex differences in tumorigenesis by assessing the number of Ki-67-positive cells [Ki-67(+)] in urethane-induced mice lung tumors and the effect of sodium valproate (NaVP) in BALB/c mice. Gonad-intact and gonadectomized female and male mice were divided into the following groups: i) Treated with urethane, ii) treated with urethane and NaVP and iii) go...

Sex determination of the gonad is an extraordinary process by which a single organ anlage is directed to form one of two different structures, a testis or an ovary. Morphogenesis of these two organs utilizes many common cellular events; differences in the timing and execution of these events must combine to generate sexually dimorphic structures. In this chapter, we review recent research on th...

Ubiquitin C-terminal hydrolases (UCHLs) are a subset of deubiquitinating enzymes, and are involved in numerous physiological processes. However, the role of UCHLs during gonad development has not been studied in crustaceans. In this study, we have first cloned and analyzed expression profiling of Sp-uchl3 and Sp-uchl5 genes from mud crab Scylla paramamosain. The full-length cDNA of Sp-uchl3 is ...
