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.

Single Transverse Palmar Crease
34,00 € *
ggf. zzgl. Versand

High Quality Content by WIKIPEDIA articles! In humans, a single transverse palmar crease is a single crease that extends across the palm of the hand, formed by the fusion of the two palmar creases that people typically have. Because it resembles the usual condition of non-human simians, it is also known as a simian crease or simian line, although these terms have fallen out of favor due to its pejorative connotation.The presence of a single transverse palmar crease can be, but is not always, a symptom associated with abnormal medical conditions, such as Fetal alcohol syndrome, or with genetic chromosomal abnormalities, including Down syndrome (chromosome 21), cri du chat syndrome (chromosome 5), Noonan syndrome (chromosome 12), Patau syndrome (chromosome 13), Edward's syndrome (chromosome 18), and Aarskog-Scott syndrome (X-linked recessive). Bilateral or unilateral single palmar creases are also associated with aberrations on chromosome 9.

X-Linked Alpha Thalassemia Mental Retardation S...
39,00 € *
ggf. zzgl. Versand

High Quality Content by WIKIPEDIA articles! Caused by mutations in the ATRX gene. ATR X syndrome is characterised by severe learning difficulties, a characteristic facial appearance, abnormal genitalia and alpha thalassemia. The ATR protein affects the 3D structure of chromatin in the cell nucleus. Transcriptional regulator ATRX also known as ATP-dependent helicase ATRX, X-linked helicase II, or X-linked nuclear protein (XNP) is a protein that in humans is encoded by the ATRX gene. Transcriptional regulator ATRX contains an ATPase / helicase domain, and thus it belongs to the SWI/SNF family of chromatin remodeling proteins. This protein is found to undergo cell cycle-dependent phosphorylation, which regulates its nuclear matrix and chromatin association, and suggests its involvement in the gene regulation at interphase and chromosomal segregation in mitosis.

Down Syndrome
34,00 € *
ggf. zzgl. Versand

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Down syndrome is a chromosomal condition and a type of mental retardation caused by an abnormal number of chromosomes. According to statistics, Down syndrome affects 1 in 1,000 to 1 in 1,100 newborns worldwide, causing intellectual and physical disabilities. While in the early 1900's people affected by the disease had an average life expectancy of ten years, today 80% of patients reach the age of 50. Learn more about the causes and symptoms of the genetic abnormality as well as management of Down syndrome in this book.

miRNAs in the bovine ovary and placentas
68,00 € *
ggf. zzgl. Versand

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.

Genotoxic Effect of Citronella Oil in Mice Mus ...
49,90 € *
ggf. zzgl. Versand

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.

Penta X Syndrome

ggf. zzgl. Versand

Penta X syndrome is a very rare chromosomal disorder where the karotype of the patient is 49, XXXXX. This means that there are 2 X chromosomes making the patient phenotypically female but there are an additional 3 X chromosomes. The patient exhibits certain features which could be confused with Down syndrome. They have low-set, abnormal ears, slanting palpebral fissures and a flat nasal bridge. They may also have a low hairline, clinodactyly (curavture of the digits), poor tone and heart/kidney defects.
