Aneuploidy

Abstract: The pre- and post- treatments effects of Habak, one of Mentha longifolia subspecies, as one of the famous folk medicine was studied in mouse bone-marrow cells in contrary to the mutagenicity of cyclophosphamide (CP). Male Balb/C mice were pre- and post-treated orally with aqueous extract of Habak at variable concentrations (250, 500 and 1000 mg/kg b.wt) for 24h and 48h respectively. Mice were injected intraperitoneally with CP for 24h pre- and post-treatment with Habak. Assessment of cell

Type of lifestyle, diet, and mindset are some examples of choices a person can make to better his/her life. Race, height, and genetic disorders are some characteristics that we cannot control. However, for genetic disorders, there are options to lessen the likelihood of having a child born with a disability. Taking prenatal vitamins, attending routine checkups, not drinking alcohol and not smoking are just a few proactive options that can help prevent an abnormal pregnancy. Another option to ensure

Unit Title: Biochemistry of Nucleic Acids (A.C. 5.1 and 5.2) The human body is made up of trillions of cells and each cell has a nucleus, filled inside with chromosomes made of a long string of DNA (deoxyribonucleic acid) wrapped around a special protein called histone (American cancer society 2014). According to Cancer Research UK (2014) DNA by itself is made up of thousands of genes, which are a coded message that tell the cell how to behave and divide. As such if the signals are missing, cells

Taurodontism: Review and Case report Abstract Taurodontism can be defined by Keith as “a tendency for the body of the tooth to enlarge at the expense of the roots.” Characteristic features of taurodontism include an enlarged pulp chamber with apical displacement of the pulpal floor and no constriction at the level of the cementoenamel junction. While it is a common tooth anomaly found in permanent dentition mostly affecting the molars, in primary dentition, it is rarely seen. Taurodontism has a

the same condition and make decisions accordingly. When we consider today’s society and people choosing to have children later in life, I think PGD is also good for couples struggling to conceive due to advanced maternal age allowing them to have aneuploidy

For the human female, pregnancy is a period of time that is celebrated in most cultures. However, reaching the point where a pregnancy successfully results in the birth of one or more healthy offspring can take more than one attempt. Wilcox et al. (1988) provided the conservative estimate that thirty-one percent of all pregnancies were unintentionally lost, with twenty-two percent of pregnancies being lost before they were clinically detected using delicate detection of hCG hormone levels in a sample

Congenital heart disease’s incidence depends on how the population is studied. With better diagnosis through the introduction of echocardiography the incidence figures of congenital heart diseases has raised from the range of 5-8 per 1000 live births to 8-12 per 1000 live births (Hoffman JIE, 2013). All the countries have similar incidence of congenital heart disease. Some minor differences in types of congenital heart disease by country are there. China and Japan for example have a higher

Section One: Biological concepts/ideas/processes. A popular socio-scientific issue discussed in our society recently is the use of In-vitro Fertilisation (IVF) and pre-implantation Genetic Diagnosis (PGD).1 In-vitro Fertilisation (IVF) was established to treat infertility caused by blocked or damaged fallopian tubes.1 IVF is usually used to treat a variety of infertility problems but it can also screen for any genetic disorders.1 There are six stages in IVF, ovarian stimulation, egg collection,

The process of nondisjunction can occur in human development during phases in meiosis and mitosis. The irregularity results in an abnormal amount of chromosomes in the produced cells and causes alterations in those who are affected. Nondisjunctional consequences can be seen in these five examples of genetic inheritance conditions discussed in this paper: Down syndrome, Patau’s syndrome, Edward’s syndrome, Klinefelter syndrome, and Turner’s syndrome. The Mendelian principles of genetics developed
