Sodium Azide There is perhaps not a lot known about this chemical and what it can do to/for people. One important aspect is to know what the chemical is made of, doing so will give someone a general look into its makeup. Secondly, “What is something we use this chemical for in everyday life”. Lastly, “How does this affect our cell breathing process?” From these topics, one can gather a general sense of what this substance does and whether or not it should be strayed away from. Of course it…

The laws of heredity discovered by G. Mendel are similar for all complex life creatures and he concluded that genes come in pairs one from each parent inherited as distinct units. Also, the mathematical patterns of inheritance as well as genes segregation and their appearance in the offspring as dominant or recessive traits were determined during his genetic experiments with pea plants and outlined three laws oh inheritance. First, the Law of Dominance is expressed where one allele dominates…

Ciminelli and Osseo-Asare, 1995; Lowson, 1982). Anderson (1951) reported 26 kJ/mol in the study of oxidation kinetics of galena (PbS) while Stenhouse and Armstrong (1952) reported an activation energy of 20 kJ/mol for the alkaline oxidation of pyrite. Koslides and Ciminelli (1992) suggested that during alkaline oxidation of sulphides, there is a change from chemical (activation energy > 40 kJ/mol) to diffusion (activation energy < 40 kJ/mol) control as the rate determining step when…

Sensitivity of Cancerous C.elegans with Mitochondria Dysfunction Mitophagy is a selective autophagic elimination of damaged or excessive mitochondria, especially when cells are under adverse stress. Mitophagy has been identified as the cause of various human diseases and even cancer. In recent years, researchers gradually regard mitophagy as the target for cancer treatment, although the role of mitophagy in the developmental and metabolic process of cancer is still not clear. In this…

INTRODUCTION: Over prescription and extensive use of antibiotics has caused antibiotic resistance at an shocking rate (Mezger et al.2014). The main aims of Antibiotic sensitivity testing is detecting possible drug resistance in common pathogens by in-vitro testing of bacterial cultures with antibiotics to determine susceptibility of bacteria to antibiotic therapy. The tests are frequently used when the etiologic agents are members of species capable of resistance to commonly prescribed drugs…

Intro With a significant importance to the world economy, the human body, and the environment, copper has been studied and manipulated to explore its uses and properties. In the experiment performed, the copper cycle was observed by placing copper through a series of chemical reactions to demonstrate the different reaction types. Materials and Methods To begin the experiment, a 50 mL beaker was placed on a hot plate with a ring stand along with a fume hood made out of a funnel, rubber tubing,…

Introduction/Purpose: Chemicals all perform different reactions when dissolving into different chemicals, and in the lab “Our First Lab” my group and I observed one of these chemical reactions. The purpose of the lab was to witness the chemistry behind these reactions in action, so we could put research and observations together on how it was possible for something to illuminate with only a forced bend to it. Observed how each light sticks glow depended on the temperature they were exposed to,…

Introduction: Enzymes play a major role in biological systems to catalyze and control different reactions. The study of enzymes’ behaviors toward substrates and products is significant to understand various enzyme catalyzed reactions in living organisms. One of the most important enzymatic group is cytochrome P450 (CYP450) which contribute to the metabolism of many endogenous as well as exogenous substances such as drugs. Although there are several subtypes of CYP450 family, CYP450 1A1 is going…

Mucor hiemalis showed high resistance to (Zn, Al) (Table, 37 & Fig. 46). The most interesting, high concentrations of zinc stimulated the growth better than low concentrations (Table 37), Aluminum could stimulate the growth of the fungus slightly in concentrations 100 ppm and 300 ppm respectively. Lower and higher concentrations slightly inhibited the growth but aluminum couldn’t stop the growth of the fungus (Table 37, Fig. 46). While (Mn , Cu and Pb) succeeded to stimulate the growth of Mucor…

Abstract In this study, a CO2-respensive GM-AD-HA hydrogel derived from electrostatics crosslinks and supramolecular bond will be produced and studied about its mechanical properties and physiological performance. It is expected to have application in restoring cartilage and controllable delivery of Epirubicin Background of research Hydrogels have crosslinked microstructure and can swell up in water without resolving. Their soft and rubbery nature minimizes inflammatory reactions of the…
