Molecular basis of aging in relation to fertility

Aging is defined as “a progressive, time-dependent deterioration of an organism’s capacity to respond to environmental changes, which ultimately makes it susceptible to death” (Allen and Balin 4). It is a widely-accepted idea that aging is a natural process that occurs in all living organisms. Since the process of aging most likely would be affecting an organism’s overall body functions, it would also greatly affect its capacity to reproduce, eventually leading to a decrease or the loss of fertility of the said organism (Liu and Case 1169). At present, there are numerous links between chromosomal and DNA damage not just to the aging process of an organism but also on fertility. A female’s capacity to conceive and give birth, or a male’s capability to contribute in conceiving a child is called fertility (Masoro 161). In order to proliferate the species well into numerous and succeeding generations, organisms must be able to produce as much offspring as possible that are able to adapt to the current environment that they live on. For that to happen, the process called natural selection takes place (Torday and Rehan 12). Also, the energy that flows within the organism is appropriated in such a way that during the process of reproduction, most of the energy from the consumption of food is distributed to the body’s reproductive systems, mostly to the rapidly-dividing cells called the gametes. ...

Genes may be incorporated into bacteria, plants or animals. In this process recombinant DNA (rDNA) technology is used to incorporate gene of interest into organisms and that organism in which gene is inserted is said to be genetically engineered. Through this process off springs with unique characters are produced. Recombinant DNA is also referred to as Chimera. By the combination of two different strands of DNA a new strand of DNA is obtained. The first step in genetic engineering involved the production of hormone insulin which is important and helps the cells to properly absorb sugar. …

Water has been obtained as the primary constituent of all living organisms. Be it plants or animals, the water has its role in the process of metabolism. It is required in the process of photosynthesis where light energy is utilized splitting the water molecule such that the hydrogen gets separated and the oxygen is released in the air. Many substances in the body are hydrolyzed by water as well. For example, it is capable of breaking amino acids bonds in proteins and peptide linkages of monosaccharide in polysaccharides. Diffusion of several materials is also obtained through the component of…

Staining is one of the techniques used in the characterization of cancer cells. The most commonly used staining methods and Hematoxylin and Eosin staining. Generally the two methods have been used to differentiate between the nucleus and the cytoplasm of cells. Hematoxylin stains the nucleus purple while Eosin stains the cytoplasms pink. Cancer cells can also be stained particularly to differentiate them from other cells. However, it is imperative to note that there are preparation processes that should take place in order for tissue staining to be specific and relevant (Ahmed, 2007, p.490).…

People lacking the absorption ability of vitamin B12 remain with the disease for the rest of their lives. Parietal cells found in the gastric cells are responsible for production of hydrochloric acid which is important in digestion as it provides a favorable medium for enzyme reaction. The serum found from patients having this disease react with ? and ? sub units. The antibodies are used for diagnostic purposes. This experiment involves testing of serum of antibodies from various patients to determine if they react with the sodium pump which contains ? and ? sub units. This will help in…

This process is important because it is a requirement needed for the maturation of red blood cells, putting forward a relation with the disease2. Parietal cells are found in the gastric glands where there major function is to produce hydrochloric acid that is involved in the first stages of digestion. For gastric acid secretion, the gastric H positive or the proton pump enzyme that consists of ninety five kDa alpha subunit and a sixty to ninety kDa alpha subunit3. Auto anti bodies contained in serum from different patients having pernicious anaemia react with either or both of the alpha and…

Plant lipases are often considered to be involved in regulating certain plant growths and developments (Bos and Laxminarayan, 2011; 42). They are mainly found in seeds where triglycerides are stored in the form of intracellular structures or the oil bodies. Lipases usually hydrolyze triglycerides to fatty acids and glycerol that produces energy needed for seed germination. The plant lapses are usually classified into three main groups with the first group consisting of the triacylglycerol hydrolases that are mainly found in seeds. Their study is vital since they are responsible for seed…

In obtaining the right tissue for the examination, there are two distinct methods that can be employed. That is the physical examination technique and the liver biopsy technique. During physical examination, the medical history of the suspected patient is checked and more attention is paid to the patient’s abdomen. Presence of lumps in the liver can be felt as a patient lies flat with the liver being swollen. Other cases present an enlarged spleen and ability to hear a unique sound/noise when a stethoscope is used to listen to the blood vessels. The noise is usually caused by tumor pressure…
