  • Amyloid Beta Protein Analysis

    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…

  • Caroy Case Study

    Is it worth it to use Carnoy’s solution as a complementary therapy of benign odontogenic tumors treatment? An in vivo study in Wistar rats Shot title: Carnoy’s solution effects in mandible of rats Summary In order to quantify osteonecrosis, blood clot and bone neoformation after Carnoy’s solution (CS) and saline application in mandibles of Wistar rats, a monocortical defect was created bilaterally on right/left buccal cortical of Wistar rat’s mandibles and received one application of 5…

  • Benefits Of Potassium Channels

    Potassium channels (KC) are selective transmembrane proteins that allow K+ ions flow down an electrochemical gradient across cell membrane, thus controlling plasma membrane potential in both excitable and non-excitable cells (Szabo, Zoratti&Gulbins, 2010). Evolutionarily conserved KC family is one of the larges and most diverse of ion channels (Table1). Its diversity comes not only from a large number of genes coding for main subunits (over 80 mammalian genes). Many other processes such as…

  • Essay On Neural Transmission

    Estimating the speed of neural transmission from hand-ankle (treatment A) and hand-hand (treatment B) Introduction A neuron is a specialised cell transmitting nerve impulses and its function is to transmit information within the nervous system which is a network of nerve cells and fibres which transmit nerve impulses between parts of the body. Neural transmission occurs when a neuron is activated (sends out an electrical impulse). Activation of a neuron takes place when the neuron is stimulated…

  • Maximum Contraction Lab Report

    Introduction: Temperature can affect the rate at which an action potential is generated to excite an action potential within a given skeletal muscle. Maximum contraction is the ability of the muscle to recruit and produce its greatest force during a contraction, and we can observe these effects by using a grip force transducer, which records the functional grip force of the hand. Therefore, the purpose of this lab was to discern how varying temperatures affect maximum contraction. I…

  • Green Fluorescent Protein (GFP)

    as the firing of action potentials in neuronal cells in the brain. The research presented in the paper “High-Fidelity optical reporting of neuronal electrical activity with an ultrafast fluorescent voltage sensor” shows just how far brain mapping has come and how far it still has to go before all pathways are truly understood. This paper presents the medical community the opportunity to harness the versatility of Green Fluorescent Protein (GFP) in order to show how action potentials are…

  • Nernst Equation Lab Report

    investigate the ionic basis of the neuron’s resting membrane potential (Vm). We examine how this potential is affected by potassium ion [K+] concentration and permeability using Orconectes rusticus crayfish abdominal muscles, and we ask whether or not the Nernst Equation solely based on [K+] can also predict the cell’s resting membrane potential. We predicted that [K+] concentration had a significant influence on the membrane potential and thus the Nernst Equation was an accurate predictor of…

  • Extracellular Potassium Experiment

    In order to determine the extent to which the reversal potential for potassium determines the resting membrane potential of a given cell, a mechanism is needed to determine the change in membrane voltage across the cell in different extracellular potassium solutions. The intracellular recording technique consists of puncturing a prepared cell with a conductive pipette. The difference in potential between the extracellular electrode and the wire in the pipette is recorded and displayed on the…

  • The Similarities Between Total Recall And We Can Remember It For You Wholesale

    Dreams, are they fantasy or a longing for something once forgotten? For Douglas Q, his dreams seemed all too real to be anything more than a past life. The action packed movie Total Recall and the short story “We can Remember it for you Wholesale” have many similarities and differences throughout one another. The greatest differences being in the characters, settings, and plot. The short story introduces us to Doug Quail, Kirsten, Dr. McClane, and Interplan. Doug Quail, the main character,…
