The primary inflammatory cytokines: Tumor necrosis factor (TNF) is a proinflammatory cytokine which is produced by macrophages, T cells, B cells, natural killer cells, fibroblasts, neutrophils, keratinocytes and tumor cells [13]. It is produced during early inflammatory response. It mediates the production of other cytokines, chemokines and adhesion molecules [14]. It also increases vascular permeability, which leads to migration of activated immune cells to the site of infection [15,16]. TNF…

Safety Data Sheets (SDS) is required by Hazard Communication Standards to be issued by any chemical producers to explain the threats and menaces the chemicals pose on the users. The chemical focused on today is Ethidium bromide. The purpose of this is to learn and familiarize oneself with safety data sheets in order to understand the hazards and protective precautions needed to be taken while handling a certain chemical (in this case: ethidium bromide). III. Data The 16 sections of the SDS…

order to kill any harmful microorganisms that might have been present in the canned meat. Since its accidental discovery, D. radiodurans has been intriguing scientists with is astonishing resistance to ionizing radiation, UV radiation, electrophilic mutagens, oxidizing agents, and desiccation.
