Eukaryotic cells have numerous mechanisms to protect themselves from pathogens. The innate immune response is the first line of defense against these pathogens. Pattern associated molecular factors (PAMPs) are viral factors including proteins‚ lipids‚ and viral nucleic acids that are recognized by pattern recognition receptors (PRRs) within the cell. During viral infection‚ PAMPs accumulate in different cellular components and once recognized by the PRRs activate the intracellular signaling pathways

The Use of Marijuana in the Treatment of Psychological Disorders The use of marijuana as a medicinal treatment has been met with much controversy. Public opinion of marijuana use‚ whether recreational or medical is sharply divided. Some dismiss medical marijuana simply as a hoax to make it legal. Others are adament about the unique medicinal properties that it has. Both sides have used science as the backbone of their case‚ supporting claims that the others have deemed false. In this report I

than the spectrophotometric analysis. Keywords: Pentaaminchloridocobalt‚ iodometric analysis‚ spectrophotometric analysis Introduction In chemistry‚ the study of transition metals allows the scientist to witness coordination complexes form with ligands‚ such as a non-metal atom (electron donor). Another way of looking at the electron donor is as a Lewis base that is a compound or ionic molecule that can donate an electron pair to an acceptor molecule. In this experiment‚ the pentaamminechloridocobalt(III)

Many metals and inorganic compounds are known to exhibit thermochromic behavior either as solids or in solution. It has been suggested that such thermochromic behavior arises from one of the following mechanisms (1) phase transition (2) change in ligand geometry (3) equilibrium between different molecular structure (4) change in the number of solvent molecules in the coordination sphere Inorganic thermochromic systems have not enjoyed widespread textile application as the observed change in color
