Structure of the Bacterial Cell Wall Bacterial cells differ from mammalian cells due to highly developed cell walls outside the cytoplasmic membranes that provide structural integrity and shape to the cell. Bacteria live in dilute aqueous environments, which causes an intracellular pressure equivalent of 10-25 atm. Without the structural support of the cell wall, the cell is susceptible to lysis and osmotic rupture due to osmotic rupture due to turgor pressure. Figure 1: Comparison between…

The growing problem of antibiotic resistance is becoming clear in India, where 58,000 babies have died from infections that could not be cured with antibiotics (Harris, 2014). Adults are susceptible to these antibiotic resistant illnesses as well, 45 year-old singer Uppalapu Shrinivas died after contracting an infection (Harris, 2014). However, babies are at a greater risk because their immune systems are not as strong as an adults (Harris, 2014). One of the infants that died due to a resistant…

stress are involved in the spiraling vicious inflammatory cycle. The presence of antioxidant and anti inflammatory properties of γ-Oryzanol from rice bran oil is due to its ability to inhibit eicosanoids production, reduce oxidative stress, matrix metallo proteinases and C-reactive protein in inside the environment of macrophages (Rukkumani et al, 2012). Rice bran could reduce the levels of nitric oxides, Il-1β, Il-6, TNF-α, COX-2 and 5-LOX expressions in mice (Choi et al, 2013). Recently, it…

containing water vapour. In this atmosphere, hydrolysis and condensation takes place. Finally the films are hardened by a high temperature cycle to form transparent metal oxides. Any hydrolysable compound including halides or nitrates but preferably metallo-organics are suitable for this process. The important control parameters are the viscosity of the solution, the pulling speed and the firing temperature. The rate of heating also needs to be controlled to avoid cracking of the films.…

Coordination complex A coordination compound is the result of the reaction of lewis acid and lewis base in which neutral molecules called ligands make coordinate covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate…

This allows for making very specific fullerenes that could be needed for other reactions.3 For example triazafullerene, C57H33N3, has successfully been created using this method.3 This is a step toward a potential route to hetero- and endohedral metallo-fullerenes; as well as adapting this synthesis in a way so they can encapsulate small molecules inside the fullerene.3 While scientists are still presently researching ways to adapt the surface catalyzed synthesis; Kurotobi and Murata…

Question 4 Answer: Smoking damages the whole body, but for this answer, I am going to focus on smoking and the changes to our respiratory tract, skin blood vessels and antioxidant levels. Respiratory tract: “(1) Nicotine constricts terminal bronchioles, which decreases airflow into and out of the lungs. (2) Carbon monoxide in smoke binds to hemoglobin and reduces its oxygen-carrying capability. (3) Irritants in smoke cause increased mucus secretion by the mucosa of the bronchial tree and…

Introduction Guatemala has become the leading place for conducting researches on religions in Latin America. The predominant religions in Guatemala are Catholicism, Christianity and Mayan spirituality. However, during the colonial era, Catholicism was the main religion. There has been a tremendous growth in the Protestants community. According to the The Pew Forum on Religion & Public Life, “Pentecostals represent the most rapidly growing sector of Latin American Protestantism”. The other…
