Larry 's ketoacidosis was resolved over the next few days and a further week on a medical floor, saw Larry stabilized on his previous insulin regime. Answer the following questions pertaining to the case: 1. Based on the pathophysiology a. Give reasons for Larry 's reported admission symptoms of muscle weakness, decreased skin turgor, tachycardia and hypotension. b. Describe how this situation can be corrected. A. Mr. Secord may be experiencing the following symptoms due to dehydration and…

3.1. Green photosynthesis of gold nanoparticles using aqueous extract of Baker’s yeast: One aim of the present study is the development of an improved method for derivatization of metabolites existed in aqueous extract of Baker’s yeast (Saccharomyces cerevisiae). This procedure facilitates identification of metabolites in Baker’s yeast extract and its utility for the synthesis of nanomaterials. The preparation of trimethylsilylenol ethers of metabolites was performed by treatment of the extract…

Duchenne muscular dystrophy (DMD) is a one type of muscular dystrophy. Muscular dystrophy is a group of genetic disorders, leading to progressive muscle degeneration. People suffering from most common muscular dystrophies ,Duchenne/Becker (DMD), Myotonic (MMD), and Limb-Girdle (LGMD), experience muscles degradation overtime, leading to overall muscle weakness and decreased mobility. Statistics show that the most prevalent forms of muscular dystrophy are rare. For example in 2007 in the…

Biochemical foundation for each of the four enzymatic assays performed on each cellular fraction. We performed various assays on each of the four log phase culture fractions, as well as the extracellular fraction from a stationary phase culture, to test the localization of the enzymes. For the protease assay, a specific soluble chromogenic substrate called azocasein was employed to determine presence of enzyme activity. The degradation of this substrate in trichloroacetic acid produces a colour…

throughout life, their aggregates gradually accumulate as we age. These aggregates form distinct and observable structures in the brain which generally known as amyloid deposits in the brain. Furthermore, some form of mutation increase the chance of misfolding in proteins which is the case in the genetic or familial case of NDs [22]. Though the mechanism is not clear, it has been proven that deposits of misfolded proteins are known to be neurotoxic and able to cause apoptosis in neuronal cells.…

INTRODUCTION Alzheimer’s disease is a progressive neurodegenerative disorder characterized by memory loss and dementia. The neurodegeneration is due to a formation of amyloid platelets in the brain that interrupt the normal function of it. It worsen with the pass of years and is mostly suffered by older people (Reece et al. 2014). The platelets composed by Amyloid; a harmful insoluble protein fibril which is produced by Amyloid precursor protein (APP). APP is processed in the membrane of neurons…

B cells have cell-surface immunoglobulin molecules as receptors for antigen and, upon activation, secrete the immunoglobulin as soluble antibody that provides defense against pathogens in the extracellular spaces of the body. T cells have receptors that recognize peptide fragments of intracellular pathogens transported to the cell surface by the glycoproteins of the major histocompatibility complex (MHC). Two classes of MHC molecule transport peptides…

A receptor is a molecule usually found on the surface of the cell and receiving signals (chemical or hormonal) from outside the cell. Receptors belong to class of proteins. Binding of some substance to the receptor brings about changes that direct the actions of cell containing receptor. Ligand is the molecule that binds to the receptor and it can be a peptide, a hormone, neurotransmitter, drug or a toxin etc. Each receptor possesses two functional domains: recognition domain that binds the…

manner, parts of their receptors lie extracellular (where hormone-receptor cooperations happen) and they couple with intracellular flag transducing particles by crossing the cell film. The dominant part of traditional protein and peptide hormone receptors are the G-protein connected receptors and these may either have a moderately short extracellular amino terminal area (e.g. epinephrine, GnRH) or an any longer extracellular area (e.g. TSH, LH, PTH). Extracellular hormone-receptor collaborations…

adhesion molecule have been extensively studied. ICAM5 is abundantly expressed in the dendritic filopodia and plays an important role in synapse formation with presynaptic axons, via the extracellular matrix molecule, vitronectin (63), and/or β1 integrins (32, 64). Once these connections are established, the extracellular domain of ICAM5 is cleaved, disrupting the cytoplasmic actin cytoskeleton through to α-actinin or ERM (ezrin/radixin/moesin) proteins promoting reorganization to induce spine…
