1. Biot’s respiration named after Camille Biot is an abnormal ataxic breathing pattern, where rapid series of shallow respiration are followed by a period of apnea. In order to known how AMP kinase, knock down leads to Biot respiration in mice; it is necessary to known how AMP kinase affects respiratory rate. AMP kinase is a metabolic sensor and is activated in response to stretching of the lung alveolar cells and other stressors. During respiration, the lung goes through cycles of expansion and contraction (Budinger et al., 2008). When the alveolar cells stretch during expansion, the 5′ AMP-activated ...

Multiple Choice Questions

Increased erythropoietin production Increased heart rate Increased cardiac output Enhancement in oxygen extraction The answer for this question is b. increased heart rate. A reduction in tissue oxygenation as happens in anemia stimulates increased production of erythropoietin through a complex feedback mechanism. Increased production of erythropoietin enhances erythropoiesis in anemia. Increased extraction of oxygen in anemia is a compensatory mechanism that is mediated by an increase in 2, 3-diphosphoglycerate concentrations. Increased cardiac output is the main hemodynamic compensatory mechanism in anemia that aims to increase blood flow to the body organs. An increase in heart rate ...

Transcriptional regulation of gene expression

Gene expression in eukaryotic cells is regulated at transcriptional, post transcriptional and translational levels (Tomizawa,  Lekstrom-Himes, and Xanthopoulos 17). Transcriptional control is the primary means of regulating gene expression. Eukaryotic transcriptional control functions at three levels: modulation of the activities of activators and repressors; variations in chromatin structure; and effect of activators and repressors on assembly of initiation complexes (Lodish et al. 368). Regulation of transcription initiation is the most widespread form of gene control in eukaryotes. However, in some cases, transcription may be attenuated and regulated at subsequent steps, such as during or after the transcription process (Cooper ...

Stone Formation in the Kidney/ Role of Citrate in the Kidneys

Kidney stones are calcified or solidified molecules taking place in the upper urinary tract and the kidney. Kidney stones are usually composed of calcium as oxalate, phosphate, or carbonate. Stone formation in the kidney happens when the amount of mineral salts in the urine becomes saturated, during which the mineral will automatically crystallize (Rao et al., 2011). Stone formation is further facilitated by increasing amount of calcium in urine and dehydration. High levels of calcium in urine can indicate kidney disorder, prolonged incapacitation, hyperthyroidism or overactive thyroid, excessive intake of milk or aluminum and vitamin D. Stone formation in ...

Assignment 2

PART A - (Total 15 marks)

Cephalexin and Gentamicin The mechanism of action of amoxicillin is focused on the prevention of the synthesis of the bacteria’s cell wall through the binding and inhibiting of the cell wall transpeptidases (Katzung, Masters, and Trevor, 2012). Specifically, it attaches to the penicillin-binding protein 1A found in the cell wall of bacteria. Then, the agent disintegrates the lactam ring to allow the acylation of the penicillin-sensitive transpeptidase C-terminal domain. The formation of the cross-link of the linear peptidoglycan strands is prevented by the inactivation of transpeptidases. Since the third and last stage ...

Question 1

For succinate oxidation to fumarate there is yield of 2H+ and 2 electrons; however, the process of the reaction skips one step thereby leading to 2 ATP. The resulting FADH2 electrons skips the first stage of oxidative phosphorylation by moving into the electron transport chain located in CoQ. This can be illustrated as NADH -> CoQH2. Consequently, there is 2 ATP forming stages found in the electron chain from CoQ to O2 used in this course (Schwender et al, 50). Indifferent to the first scenario, oxidation of malate to produce oxaloacetate results to NADH, with production of 2H+ and ...

1. The molecule chosen for the analysis is Immunicillin -H. It is a transition state analogue for the enzyme purine nucleoside phosphorylase (PNP). Chemically Immunicillin -H is [(1S)-1-(9-deazahypozanthine-9yl)-1,4-dideoxy-1,4-imino-D-ribitol] (Kicska et al. 2001) 2. PNP is important for the degradation of nucleotides, especially deoxy guanosine. In the absence of this enzyme, deoxy guanosine accumulates and inhibits T cell function, causing T cell mediated immunosuppression. Inhibitors of PNP were found useful in treating T cell malignancies. Inhibiting PNP using transition state analogue, triggers apoptosis of T cells. Though Immunicillin-H inhibits stimulated malignant and nonmalignant T cells, ...

Immunogenic cell death: the role of SAGE

Introduction

Millions of cells are always being removed in the human body not only to regulate and coordinate the body’s biochemical pathways but also to keep the cells healthy. This particular systematic removal of cells occurs through a selective mechanism called cell death or apoptosis process. Apoptosis is not a new concept in the understanding of the biological workings of the body. This homeostatic death of body cells has been defined as a tolerogenic or a non-immunogenic event for many [1]. However, new discoveries have unearthed the existence of a different concept ...

Introduction:

Enzymes are protein molecules that act as catalysts to break down substances living thing need to sustain life. Most chemical reactions are too lengthy to do this on their own; even in the cases of relatively thermodynamically favored reactions like that of the oxidation of a sugar. An example of this is the oxidation of glucose to produce water, carbon dioxide and energy. Glucose on its own can remain exposed to air for years without any appreciable oxidation. Nevertheless, it is one of the substances most quickly broken down and absorbed in the human body due to the digestive system’ ...

Introduction

Prozac [fluoxetine hydrochloride] is commonly regarded as a first-line therapeutic medication for adolescents due to its supposedly better risk ratio than other antidepressants (Meeker, et al., 2015; Capitao, et al., 2015). It is also currently the most commonly used among selective serotonin reuptake inhibitor (SSRI) active ingredients, more than sertraline, escitalopram, venlafaxine (Wagner, 2015). However, its link to suicide cannot be ignored; or to birth defects and low libido (Naish, 2013). Despite the euphoria over it, a dampening cloud can be felt in the background. Is it worth risking adverse effects with Prozac? Is the risk for death or deteriorated ...

Connective tissue growth factor induces collagen I expression in human lung fibroblasts through the Rac1/MLK3/JNK/AP-1 pathway

Many lung inflammatory diseases present pulmonary fibrosis as one of the symptoms, which is characterized by shortness of breath, chronic coughing and discomfort in the chest. It causes modifications of the lung tissues due to overgrowth, hardening and scarring. This occurs mainly due to deposition of collagen, an extracellular matrix (ECM) protein, whose turnover is regulated by fibroblast. Fibroblast is an important cell regulator that is enlisted by a site of injury. This process is driven by release of transforming growth factor-β (TGF-β), platelet-derived growth factor, interleukin-6 (IL-6), and IL-8/CXCL8. Previously, fibroblast was thought to express no or very ...

Introduction

All cells carry out cellular respiration in order to meet their energy requirements and to form metabolic intermediates that can be used to form secondary products. Amongst those products formed as a consequence of cellular respiration, are ATP and CO2. The formation of ATP in the cells occurs through the use of organic molecules available in the form of food (Lehninger, Nelson, & Cox, 2008). When oxygen is not available, ATP formation goes through a fermentation process, usually, referred to as alcoholic fermentation. The process utilizes a number of different sugars as the starting material. These sugars include fructose, glucose, and sucrose. The ...

Researchers have embarked on finding solutions to the nagging issue of cancer among human beings, which are commonly based on the behavior of the mutant carcinogenic cells in the body. Understanding the environment that favor mutation and proliferation of mutate genes is a remarkable approach towards getting a long life solution. In this respect, it has been identified that targeting blood vessels development in a tumor tissue ...

Analysis of Culture Cell KU812F with Three Protocols

Abstract Protein analysis for cancer cell research has been found to be extremely reliable. The culture cell KU812F (chronicle myeloid leukemia cell line) was used for this laboratory. Globin gene switching was observed by evaluating the gene expression in the cells. Gene expression and protein folding were provoked. Gene expression is the process of transcribing DNA to cDNA and then used qPCR to study gene expression. cDNA was translated into mRNA which in turn is translated into a protein. mRNA concentration was analyzed. The three protocols were Reverse Transcription Polymerase Chain Reaction (RT-PCR), Enzyme-Linked immune sorbent assay (ELISA), and ...

It is normal for any living organism to want to live in a hospitable environment. For the fungi, which reproduce through the production of spores which are dispersed by a variety of mechanisms, there is a need for the spores to germinate only when the environmental conditions are favorable for germination. Goldstein (2011, p. 28) asserts that dormancy can be viewed as a survival mechanism for the fungi during which the fungi “remains in a state of suspended animation until the environment becomes hospitable”. Spore dormancy represents an important character influencing the competitiveness of difference species of fungi. There are two types of fungi ...

1. Which of the following is an antidote for benzodiazepine overdose or toxicity?a. Buspirone (BuSpar)b. Hydroxyzine (Visteril)c. Flumazenil (Romazicon)d. Naloxone (Narcan)There is one other drug overdose antidote in the above list. Name the drug and its mechanism of action. Flumazenil (Romazicon®) is another drug given to reverse the depressant effects of benzodiazepine and thus useful for overdose treatment. It acts as a competitive antagonist of benzodiazepines, having high affinity to GABAA receptors, which is the BZD binding site. This allows it to specifically target benzodiazepine and drugs with similar MOA such as zolpidem, but not other ...
