Introduction to 46 XY DSD: 5 RD and AIS
45,90 € *
ggf. zzgl. Versand

Differentiation and development of internal and external male genitalia is under the influence of several genes and endocrine factors. The defect at any step in this pathway may result in abnormal sexual differentiation and development described as DSD. It is a group of uncommon congenital conditions in which the development and differentiation of chromosomal, gonadal and anatomical sex is discordant and covers a wide spectrum of phenotypes.Ambiguous genitalia results from either excess androgens in a genetic female or deficiency of androgen in a genetic male. There are a number of situations where this can happen. CAH is the most common form of 46,XX DSD. Androgenic exposure in utero causes virilization irrespective of the genetic sex. Also in absence of androgens an XY child will look like a female at birth. Therefore a child with ambiguous genitalia could be a virilized female or an under-masculinized male.

Reversible Phosphorylation and Oocyte Maturation
68,00 € *
ggf. zzgl. Versand

Revision with unchanged content. The delicate nature of reproduction is evidenced by the fact that the female gamete is notorious for having high rates of chromosomal abnormalities. It is estimated 10-25% of all human conceptions are chromosomally abnormal due to an error in chromosome segregation during meiosis. Furthermore, studies indicate greater than 95% of this human aneuploidy is attributable to defects within the meiotic machinery of the oocyte, rather than that of the sperm. This results in chromosomal non-disjunction leading to embryonic aneuploidy, miscarriage, infertility and congenital defects. Nevertheless, causative factors and intraoocyte biochemical signaling pathways causing these chromosomal perturbations are unknown. Therefore, elucidating regulatory mechanisms involved in oocyte meiosis is imperative to fully understand this complex process and establish potential therapies to circumvent oocyte derived embryonic aneuploidies. This book will review the origin, as well as development and growth of the oocyte. Furthermore, major mechanistic and cellular events occurring during oocyte meiosis critical to ensure proper development and cellular ploidy will be discussed, focusing on the role of reversible phosphorylation in control of these processes.

Genotoxic Effect of Citronella Oil in Mice Mus ...

Citronella oil is a volatile oil obtained from the plant Cymbopogon winteratus.The oil contains approximately 30% citronella and 40% geranial.The therapeutic properties of citronella oil are antiseptic,diaphoretic,insecticidal, paracidal,deodorant,stimulatant and tonic etc.It is also used in cosmetic industry.Hence,human beings are in direct contact contact with citronella oil.Therefore,the present work was an attempt to evaluate the cytogenetic toxicity of this oil on mitotic chromosome,meiotic chromosome,sperm counting and sperm head morphology of mice Mus musculus.The result suggested that all three doses i.e 50 ppm,100 ppm and 200 ppm significantly increased the chromosomal abnormalities both in bone marrow and primary spermatocytes. Notable increase in the frequency of abnormal sperms as well as significant reduction in epididymal sperm count were also ovserved in treated mice. On the basis of above accounts it is clear that the test chemical i.e citronella oil is not fully safe. It may cause cytogenetic toxicity, mutgenicity as weel as carcinogenicity.

miRNAs in the bovine ovary and placentas

MicroRNAs are the major class of gene regulating molecules playing pivotal roles at post-transcriptional level. Two subsequent studies on miRNA are presented here. The 1st study aims to identify and characterize miRNAs in bovine ovary through cloning, expression analysis and target prediction. The 2nd study aimed to elucidate the difference in expression profile of miRNAs in the placenta at day 50 derived from Somatic cell nuclear transfer, in vitro production and artificial insemination pregnancies by quantifying 377 miRNAs and other systematic procedures. The study reveals a massive deregulation of miRNAs which were poorly reprogrammed and affected as large chromosomal cluster as well as miRNA families in the NT and IVP placenta compared to that of AI. Identified deregulation of miRNAs might associate to the abnormal placentogenesis in NT or IVP pregnancies, which are the results of aberrant genetic and epigenetic modification. Altogether, this Book describes the discovery of miRNAs and their functional networks in the bovine ovary and elucidates the pattern of expression of miRNAs along with their regulatory mechanism in the placenta derived from pregnancies of various origins.

Chronic myelogenous (or myeloid) leukemia (CML) is a cancer of the white blood cells. In CML, stem cells of bone marrow forms the abnormal white blood cells that interrupts the normal function of RBCs and normal WBCs. CML occurs due to Philadelphia chromosome (i.e. the result of chromosomal translocation) that governs the synthesis of oncoproteins, which is responsible for uncontrolled growth of abnormal WBCs. In the field of molecular modeling, docking is a method which predicts the preferred orientation of one molecule to a second when bound to each other to form a stable complex. In such a way here we will use this Knowledge of the preferred orientation in reference to oncoprotein and trying to design a potential ligand that interact with cancer causing protein and make it incompatible for their further functioning.
