Glioblastoma multiforme (GBM) is a type of malignant brain tumor typically found in the cerebral hemispheres, but can be found anywhere in the brain or spinal cord. These tumors are highly malignant meaning a large number of cells reproduce at any given time. There are two main types: primary, or de novo meaning the tumors make themselves known quickly and are extremely aggressive, and secondary meaning the tumors have a slower growth history but are equally aggressive . Secondary tumors are…

Water fluoridation is a process of adding fluoride to public water until a desired level of fluoride in the water is reached. It has been used as a public health measure to reduce tooth decay and it is important for oral health especially the teeth. Natural water contains a small amount of fluoride but it is limited and insufficient to provide a significant change in the improvement of oral health. Water fluoridation adds fluoride to public water and it is adjusted to between 0.7 - 1.0 parts per…

indole-3-acetic acid can be carried out (35). The yeast extract solution under visible light act as reducing and capping agents. The reduction of noble metal ions to nanoparticles catalyzed through oxidation of glucose to gluconic acid by providing electrons (36, 37). The formed nanoparticles can be also stabilized by the presence of Van der Waals forces between the negatively charged oxygen groups present in the molecular structure of the butane-2,3-diol or indole-3-acetic acid, and the…

Behe desires to show us that far more than just natural selection is in play in the evolutionary process, he does this through the view of the electron microscope. Darwin could have been forgiven for not seeing the microscopic differences in biological structures whilst he worked on his observations and studies. It is easy to see how Darwin could have imagined that legs or arms would have been closely…

Introduction The incidence of acne vulgaris throughout the world has previously been reported as 9.4%,1 while other estimates in the literature indicate an upper limit for the rates for adults as 50% and 80% for adolescents.2 Outbreaks can eventually lead to scarring or skin discoloration3 and severe forms include high levels of general inflammation as well as the presence of large nodules. However, the physical effects are of less general significance than secondary psychological reactions,…

was confirmed by X-ray diffraction studies. The crystallite size of SnS2 thin films was found to increase with the increase in precursor solution volume up to 20 ml and then it decreased at the precursor solution volume of 25 ml. The scanning electron microscope established the presence of platelet-like shaped grains. The composition elements of tin and sulfur were found to be present and found to be closely nearly to the stoichiometric ratio by EDAX analysis. The thickness of these films was…

In cell theory, it is known that all cells arise from pre-existing living cells, through cell division. In cell division, this involves the supplying of identical genetic material from the parent cell, DNA and protein, to two daughter cells. It results in the daughter cells having the same number of chromosomes as the parent cell. We need cell division as it is used in reproduction of new species, growth and repair of damaged cells and tissues, and to reduce the cell size. Larger cells are…

Friction is a crucial phenomenon in metal cutting which is very complex to model. It has a significant effect on the amount of power required for removing a given volume of metal, surface quality of the finished product, and the extent of tool wear. However, many studies assume no friction in the metal cutting process due to lack of experimental techniques to directly measure the coefficient of friction. Sticking and sliding regions are the two contact regions along the tool-chip interface. A…

Asthma and chronic obstructive pulmonary disease (COPD) are among the most common and prevalent diseases in the world (Raadhika and Shanthi, 2012; Rao and Kulkarni , 2012). Salbutamol sulphate (SS) is a short-acting β2-adrenergic receptor agonist used for the relief of bronchospasm (Sharma et al., 2015). Salbutamol sulphate is readily absorbed from the gastro intestinal tract following oral administration, and it undergoes the first pass metabolism in the liver. It requires multiple dosing a day…

The research work regarding the chemical processes within/relating to living organisms is said to be biochemistry, also known as biological chemistry. The complication of life can occur during biochemical process, if we control the information flow through biochemical signaling and through metabolism chemical energy flow. Various study fields like botany, medicines, genetics, Etc.which are areas of life science, are engrossed in research related to biochemical because biochemistry has made it…
