Introduction Modes of liquid chromatography are generally divided in accordance with their aims, principles, and technology used for chromatography. Three methods are generally used in protein analysis as the most precise and reliable: affinity method, SDS-page method, and size-exclusion chromatography method. These methods are used for purifying protein solvents by...
Introduction The human body has evolved to harbor a variety of microorganisms. There are specific sites that promote the growth or colonization of the microbes which have led to the gradual development of enriched microbial flora. The important sites are skin, nasal epithelium, gastrointestinal tract, and vagina. Bacteria have dominated...
Introduction Traits that protect the crop yielding potentiality will always be vital. Advanced technologies are being used to design products for insect control such as dsRNA which generate new modes of action. Research efforts mainly focused on enhancing complex traits like biotic stress mitigation and intrinsic yield potential which are...
Introduction Billions of years ago, when the dense speck expanded, the matter and antimatter should have disappeared and left nothing but energy. Still, some amount of matter remained and filled the world with numerous particles (Sundermier, 2015). Those particles circulating through the dark matter across the universe might pass through...
Introduction This research was motivated by the observation of a faulty mutant MYBPC3 gene copy causing a lethal heart disease in people who have inherited it. Since the nature of the disorder is genetical, it was assumed gene modification with the use of the Cas9 enzyme would allow for a...
Geographic Description location in the south-eastern part of Florida (“Miami, Florida,” 2017) location of the city on the Atlantic coast the territory is dominated by flat terrain Gulf Stream flows nearly the coast height above sea averages 4.5 m Miami’s location on the ocean coast, elevation above sea level, and...
Introduction Folate is a naturally occurring vitamin that is part of the B complex group of vitamins. Folate, a water-soluble vitamin is converted to various active forms in the body. Folate is a general name used to refer to folic acid or folacin. Folate is a core vitamin that is...
Introduction Enterobius vermicularis (pinworm) is the most common among all helminths in the world with a prevalence rate of 20-40 million in the United States. Treatment of pinworm infection is fairly easy and medication can be provided at all public health facilities. This paper seeks to provide an analysis of...
Introduction Macquarie University scientists are researching on a new protein assigned the name Damini.The source of this protein is a marine organism. The researchers still do not know the full genetic make up of this organism. This has necessitated the cloning of the gene coding for this protein in Escherichia...
Introduction Chadha et al (1982) claims human Interferon alpha is protein derivative that is biosynthesized and secreted by lymphocytes under pathogenic stimulus. Allen and Diaz (1996, p.182-3) argues that the main stimulus that predispose secretion of human alpha are viruses, bacteria, parasites or tumor cells. Spiegel (1989, p.76-77) claims human...
Introduction Every expectant mother wants to be sure that her baby is healthy, well-developed, and complications do not threaten the pregnancy. Modern technologies allow detecting pathologies at an early stage of pregnancy, which makes it possible to make the necessary decisions promptly. Genetic screening (prenatal screening) is a maternally and...
Bacteria have simple digestive systems whereby food is ingested and wastes are eliminated from the body through the cell membrane by use of the contractile vacuole by the process of simple diffusion. On the other hand human beings have a more developed digestive system with various organs being used to...
Biochemistry and Molecular Biology is a course area, which has contributed hugely to life sciences. To affirm this, some molecules are often recognized as building blocks for cell formation, implying that they are fundamental to the physiology of humans. Biochemistry primarily involves the study of such molecules, and this underlines...
Introduction The preservation of wild life is the crucial issue for saving the bio diversity and the ecological balance on our planet. Originally, it should be stated that the allover efforts of governments, world organizations and separate personalities are rather highly-valuable, nevertheless, these efforts should be ten times higher and...
Iron regulation in the body Iron is a constituent of all living matter. Iron is a core factor in the electron transfer chain in the body; it is also a vital part of oxygen transport and iron storing molecules such as hemoglobin. It is also a component of host defense...
Introduction The National Zoo is situated along Connecticut Avenue in Washington, D.C. The National Zoo takes care of about four hundred species of animals. Additionally, it offers research and recreation services. Most of the animals in the park are in danger of extinction. I visited the National Zoo on 4th...
Modern genetics allow people to predict the appearance and possible abnormalities of future generations. The most prevalent human traits are brown eyes and dark hair, while the genes of blue eyes and fair hair are recessive (Lin et al., 2016). Moreover, such characteristics as freckles and dimples have the dominant...
Introduction One of the areas of polyoxometalate (POM) chemistry that has had very little research is the solution chemistry of polyoxotantalates. One of the main chemical components in this area comprises the hexatantalates. The chemical species [Ta6O19]8−, which is a positively charged ion, has immense stability in elevated pH. The...
Introduction Bacterial food toxicity refers to the extent to which bacteria can damage organs of persons who ingest food or fluids contaminated with different species of bacteria that are known to cause toxicity. The concept of bacterial toxicity in food is that the biological effects caused by the microorganisms are...
The dangers of tuberculosis (TB) still form a reality for a large segment of the global population, as it cannot be called a “disease of the past,” unlike bubonic plague, for instance. TB continues to represent a growing threat, as around 2 million people become its victims annually (Gengenbacher and...
We live in time when the nonsensical essence of religious worldview became obvious to just about anyone capable of utilizing its sense of rationale. However, it is namely the publishing of Charles Darwin’s “The Origin of Species” in 1859, which marks the beginning of a new historical era, associated with...
In vitro fertilization (IVF) is a form of fertilization that occurs outside the body in which egg cells are fertilized by sperm cells in a specially prepared fluid medium. Following the fertilization of the egg outside the body, the zygote is implanted into the womb of the mother. If both...
Introduction PCR is a biotechnological invention that is used to analyze genetic material and synthesize copies of the same. It analyses the very tiny fragments of genetic material including the damaged material to a level which can be easily studied. For the past hundred years, PCR has been the most...
Many scientists tried to understand what consciousness is and how it interacts with the world, and Anil Seth, in his speech, also talks about his findings on this topic. Seth (2017) says that people hallucinate all the time, and the images that they perceive as reality are formed by the...
When Charles Darwin visited the Galapagos Islands in the 1830s, thirteen species of finches inhabited the place. Finches show a variety of shapes and sizes of beaks, all of which are suitable for their different types of food and lifestyles. Darwin gave this phenomenon the following explanation: they are all...
Molecular biology, along with ‘GenBank’ plays an important role in genetic disorders. More than 200 single-gene disorders have been detected. It determines the molecular genetic defects in various diseases. These include amongst others cystic fibrosis, sickle cell anemia, and thalassaemia. Modes of inheritance are essential knowledge in genetic counseling and...
