Literature Review: Green Fluorescent Protein and Histidine Tagged Proteins Histidine and green fluorescent protein (GFP) tagging are important in molecular biology because they allow for purification, tracking, and quantification of target proteins (Ferrari et al., 2004; Cho et al., 2011; Deponte, 2012). Histidine tagging provides a method for isolating and increasing the amount of target protein recovered from a biological organism or mixed sample of proteins (Masek et al., 2011; Singh and…

tooth disease such as Gingivitis and Periodontal disease. These diseases are hidden below the gum line and produce toxins rapidly, and with the help of microscopes, doctors and dentists are able to cure and examine these illnesses. In conclusion, Microscopy has a had a great impact on Medical Science and it’s creation has allowed scientists to observe small organisms and record their functions/purposes. It has also given researchers the opportunity to discover cures and prevent deadly…

and liquor ratio 1∶30. The result showed that the differences were very great in the whiteness, the grease content and the bacterial content of washed chicken feather fibers. Visual observation, infrared spectroscopy, optical microscopy and scanning electron microscopy were used to characterise the feathers and residues after extraction.The conclusion was that the effect of washed chicken feather fibers by biological method was superior to that of washed chicken feather fibers by chemical…

Triangulene, a chemical similar to graphene, has long been thought to be unable to be synthesized due to its instability. A team from IBM, however, has figured out a way to create this elusive molecule. Triangulene is a flat molecule made of six carbon rings structured in the shape of a triangle. The problem with synthesizing this molecule is that it contains unpaired electrons in two of its outer carbons. These free electrons cause the molecule to oxidize almost instantly as these electrons…

spindle pulling forces cause asynchronous chromatid separation3. Cohesion fatigue was determined experimentally by arresting a cell’s metaphase through the use of proteasome inhibitors (MG132) and visualizing the chromatids separation through video microscopy. 3. SKA3 (previously named C13orf3) is a protein which plays a large role in the attachment of kinetochore-microtubules and movement of chromosomes2. SKA3 localizes to the spindle and kinetochore–microtubule interface throughout mitosis,…

Sulfamethazine remediation potential of Arabidopsis thaliana root ABSTRACT The use of antibiotics in animals either as a growth promoting or as a disease treating agent has become a worldwide trend. Antibiotics being stable bioactive compounds are not fully absorbed into the animal system and are released into the environment through animal manure. This study aims to discern the effect of one such veterinary antibiotic, sulfamethazine, on Arabidopsis thaliana root and also the possible…

A CASE STUDY ON THE IMPORTNCE OF MICROSCOPY St. Valentine’s Day Massacre The Valentine’s Day Massacre remains the most notorious gangster killing of the prohibition era. The massacre made Al Capone a national celebrity as well as brought him the unwanted attention of the federal government. The date of this massacre was 14 February, 1929 at 10.30 a.m., the people who were the victims were Frank Gusenberg, John May, Albert Weinshank, James Clark, Adam Heyer. RIVAL GANGS Gangsters ruled may of…

Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

Electron Motion Control and Imaging M. Th. Hassan Electron motion in atomic systems, which happens on timescales of attoseconds (10-18s), is at the heart of all phenomena in nature. For instance, the motion of electrons in the chemical bonds determines the structure change in the molecules. Therefore, controlling this fast electron motion, in turn, allows to control the molecular structure change. Additionally, recording snapshots of the electron motion will provide real-time access to all…

When people envision their immune system, they picture an army inside their body fighting off harmful diseases to protect you. One does not imagine the immune system attacking your own body the thing it is meant to protect. Unfortunately, when this happens it causes your body to break down as your central nervous system (CNS) begins to degenerate over time. This ill-fated reality is the result of the chronic disease Multiple sclerosis (MS). Which is an autoimmune disease that causes irreversible…
