Introduction Citrus fruit oil is a product obtained from Citrus fruit on both Lemon and Grape fruit, with strong solvent properties. It contains valuable and essential composition that is helpful to human body when applied on the skin. It affects the skin by energizing it. Chinese companies make many products...
Abstract Crystallization of L-alanine crystals can be achieved through the use of Meta-assisted and Microwave Accelerated Evaporative Crystallization (MA-MAEC) process. This is a common industrial technique that has the capacity to produce crystals with different polymorphs within a very short time, unlike other preparation methods. MA-MAEC crystallization technique poses myriads...
Transport Role Proteins transport biologically important compounds in the body. In some cases, the transported compound is sorbed by a protein molecule. This protects against destruction and ensures transport with the bloodstream (for example, albumin transport of some hormones, vitamins, medicinal compounds). This type of transport is called passive. In...
Abstract This paper sought to identify the fermenting properties of yeast cells. Yeast can be identified as a tiny plant-like microorganism (Cox 122). The main purpose of yeast is to “serve as a catalyst in the process of fermentation, which is essential in the making of bread” (Nieman 570, par....
The Anatomy of the Skeletal System The skeletal system is located in the whole body and may be divided into two parts: the appendicular skeleton and the axial skeleton. Researchers note that “the axial skeleton runs along the body’s midline axis and is made up of eighty bones,” including, for...
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 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 As the surface of the earth is covered with 70 % of water, it looks like a blue ball from far above. The well known fact is that water is the most valuable natural resource that exists and without which survival of life is impossible. About 97 % of...
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...

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 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...
Skull – consists of cranial and facial bones Cranial bones – these contribute to the cranium, which encloses & protects the brain; note they are separated by jagged boundaries called sutures; there are 8 cranial bones (note there is a right & left parietal and a right & left temporal;...
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 understanding of life in different societies is the primary task set by anthropologists, and its importance is defined by the necessity to address issues related to human existence as a whole. Such a complicated matter requires the use of specific approaches, and fieldwork is the most beneficial method...
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 development of natural science challenges the tenets of already existing theories. Today, with the help of new technologies and modern approaches, researchers are able to formulate more sophisticated ideas that affect previous discoveries. Darwin’s theory of evolution is one of the ideas that was influenced by the developing field...
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...
