    progression of neurodegenerative diseases. Hence‚ we hypothesize that apln is a previously undiscovered anti-aging factor‚ and its adequate levels are necessary for organismal homeostasis. Though some in vitro studies report that apln protects against apoptosis‚ its effect on cellular senescence and mammalian aging have never been documented. Additionally‚ there is limited understanding of if and how apln levels vary with age and whether manipulating its level affects the onset and progression of

    Naphthalimide derivatives are classified under intercalators‚ having a flat aromatic or heteroaromatic moiety and basic side chains. Amonafide is one of the most widely studied naphthalimides‚ which binds DNA by intercalation and also as Topoisomerase II inhibitors. The napthalimides showed excellent activity in breast cancer trials but failed in phase III trials due to its side effects and bone marrow toxicity [54]. The justly Naphtalene diimide (NDI) scaffold achieved recently as intercalators

    Papa Kwame Pireku Problem set 1 2.2) Antimicrobial peptides are usually produced as inactive propeptides that require cleavage by a protease to complete their activation‚ often by generating a cationic peptide that takes on an amphipathic structure capable of disrupting the cell membrane of a microbe. Also in neutrophils the antimicrobial agents are activated by proteolytic cleavage when these granules fuse with phagosome and encounter neutrophil elastase that has been released from primary granules

    Neurodegenerative Disorders: Alzheimer’s Disease 1. Amyloid Precursor Protein (APP) Alzheimer’s disease (AD) remains a major cause of senile dementia‚ which is characterised by an impairment of neuronal and synaptic function in addition to the accumulation of β-amyloid plaque and formation of neurofibrillary tangles within distinct portions of the brain (De Strooper and Annaert‚ 2000). Progression of this distinct pathology of neurodegeneration does not typically vary from patient to patient

    Biochemical Pathways of Heavy Metals Poisoning BIO101 (Principles of Biology) 6 July 2012 Abstract The biochemical pathways of heavy metal poisoning are routes by which the metals pass in the body as they impair and destroy normal cellular and organ activity. The most common types of heavy metal poisoning are caused by lead‚ arsenic‚ cadmium and mercury. They are also the most extensively studied at the moment. Lead poisoning occurs mainly by the inhibitory effect that the metal imposes on enzymes

    GENETIC MUTATIONS THAT CAUSE SKIN CANCER 2 Cancer begins when one or more genes change from their normal form. This either creates an abnormal protein or no protein at all‚ both of which cause mutated cells to multiply uncontrollably. (Association‚ 2011) Melanoma can either be caused by inherited genes or defects that are caused from environmental factors‚ such as exposure to too much sun. However‚ according to the Centre for Genetics Education‚ all cancers can be considered genetic

    Explain. Every cell contains organelles‚ the structures that carry out their specific functions. Organelles are also known as cell compartments. Eukaryotic cells have membrane bound compartments in which specific metabolic activities takes place. The organelles of the prokaryotes are not membrane bound and are simpler structures. Just like organs‚ each organelle contributes in its own way to help the cell function well as a whole. The organelles are endoplasmic reticulum‚ golgi apparatus‚ mitochondrian
