Introduction Animal experimentation has played a major role in medical research, with some reviewers linking it back to researchers such as Aristotle in 384 – 322 BC (Hajar, 2011). Worrying for some, it is estimated that over 100 million animals are used annually for experimental reasons (RSPCA, 2019), that can be spread across areas such … Read more
I. Introduction A journey to space is a journey expediting the unknown. A road that no one knows what to expect or what is about to happen. I was really fascinated by one of the most debated as well one of the least known phenomena called black hole. Black hole is place in space where … Read more
1.Review of J. Phys. Chem., 1986, 90, 2555-2560 This paper mainly focuses on the experimental and theoretical background of properties, which differ in nanoparticles from the bulk material. This change depends on the size in semi conductor crystallites of ~15Å to several hundred angstroms. The “crystallites” are named as clusters. Generally, the word ‘nanocluster’ is … Read more
Despite the ubiquitous presence of P. acnes on human tissues, concrete knowledge in relation to its pathogenic role amongst various disease states remains controversial (Portillo et al. 2013). Numerous studies have indicated the organisms’ ability to act as an opportunistic pathogen, with suggested etiological roles amongst a number of inflammatory diseases such as acne vulgaris … Read more
Abstract The Ngee Ann Polytechnic Internship Programme INT4 is a compulsory module and a prerequisite for a Diploma in Biomedical Sciences (BMS) 3-Year programme. The Internship Programme is also important in the development and growth of the student, as well to attest to the capabilities of any graduate in a professional background. Overall the Internship … Read more
Abstract: Among the possible methods for the determination of elements is flame photometry which is a type of atomic spectroscopy whereby a sample is introduced into a flame and undergoes various processes, this leads to the formation of excited atomic species that emit radiation. This method of analysis is suitable for both the qualitative and … Read more
Introduction Granulation is a process of forming or crystalizing powders into grains. It is a process in which primary powder particles are compressed to bind and form multi-particle entities that are known as granules. In the process of granulation, particles are collected together by compressing the particles and this causes them to form bonds between … Read more
Specific Aims The overall goal of this proposal is to investigate the mechanism of virus-mediated formation of double membrane vesicles within the endoplasmic reticulum (ER). The ER is considered the origin of induced intracellular structures for a number of viruses.1 It has been shown that the formation of double-membrane vesicles (DMVs) within the ER is … Read more
Genetics is the study of genes and heredity explaining how certain traits is passed on from parents to their offspring which is as a result of changes in the DNA sequence. A gene is a part of a DNA, it contains the instructions of building molecules and how they should work. Genome on the other … Read more
Whatever gives a favorable edge has always been a big deal to sustainability and to the technological changes embraced by chemical industries. On that ground, pressure is imposed to green chemistry’s advocates ensuring the environment’s health while plugging into lucrative innovations. That is why the said greener style’s potential remains at rest as long as … Read more
Modern ideal of Science attempts to specify a procedure an individual must follow to come up with a credible idea or theory. However, recently I’ve caught myself thinking that scientific method with its sequence of action wherein a hypothesis is followed by experimental verification can’t possibly describe all the advances in the history of science. … Read more
Abstract Estrous cycle is a physiological change in female individuals that associate with reproduction including rats. It has four stages categorized as proestrus, estrus, metestrus and diestrus. Rats are an ideal animal for investigation of changes occurring during the reproductive cycle due to its short cycle length. The estrous cycle in rats lasts averagely in … Read more
Stem cell research has been the biggest growth area of medical science in recent years. However, experiments are very limited as it is not possible to track stem cells in the adult human body. In this Complex world, we use models in designing and developing high functionality systems, which in turn contains numerous objects. Many … Read more
Abstract In this project I intend to explore to what extent ethical arguments about the research on Embryonic stem cells (ESC’s) and induced pluripotent stem cells (IPSC’s) have changed over the last 20 years and how factors such as, breakthroughs in research, socioeconomic and government involvement and widening access to media have contributed to these … Read more
Mohebbi et al. (2012) studied in his research, the effects of Aloe vera, gum tragacanth, and combination of both as edible coatings on the shelf life and postharvest losses of mushrooms. Physical characteristics were evaluated during storage. Mushrooms were stored at 4, 10, and 15 ”C for 13 days and physicochemical characteristics were analyzed after … Read more
