Music Essay Example | Topics and Well Written Essays - 500 words - 11

Music - Essay Example The first of these feelings that I have when listening to my favorite music is a complete and total immersion; similar to jumping into a pool. The music seems to float around me, engaging each of my senses to heights that would otherwise not be realized within the course of an average day without music. This heightened sensitivity allows my brain to focus in on the individual components of the music that derive the most empathy, joy, sadness, courage, or whatever other emotions the composer is trying to portray. However, beyond enlivening the senses, music for me serves as a tool. Naturally, depending upon the type of music that I listen to, it can ultimately be used in a way not dissimilar to a drug. For instance, when I am having difficulty sleeping, I can easily find a piece or a series of pieces of music that reflect a very calming and soothing tone; thereby helping me to get to sleep. When I need a level of focus or would like to bring out key attributes of determination or courage, I can turn to music as a way to instill such emotions. In short, music and the feelings it inspires can act as a type of stimulus to achieve the given mood that I am in search of or to induce feelings that would otherwise not come to me in a natural way. Finally, as a function of the other two ways in which music affects me, the third way is an ultimate end in and of itself. Music for me provides an escape, a type of imaginative portrait that can be painted in any number of ten thousand different ways. Even though I may have heard the song, track, or album before, the fact of the matter is that the imagery that it engages me with as a function of the aforementioned emotion and mood alteration is something that can only be described to a fellow music lover. Whereas one can read a book and have the same thought process, look at a piece of art and evoke the same images or memories, when I listen to music, there is

Coronary Artery Disease and Diabetes Mellitus

Coronary Artery Disease and Diabetes Mellitus Introduction The coronary artery supplies the blood to the heart muscles to enrich it with oxygen and other nutrients. It also carries deoxygenated blood away from the heart. The coronary artery consists of 2 main arteries; the right coronary artery which supplies blood to the right ventricles and right atrium and the left coronary artery which supplies blood to the left ventricles and left atrium. The two many arteries further divide into two; the left coronary artery divide into the circumflex artery which supplies blood to the back of the heart, the left anterior descending artery supplies blood to the front of the heart; the right coronary artery is divided into right posterior descending artery and large marginal arteries and supply blood to the sinoatrial nodes that control the heart  rhythmic rate. The coronary arteries have 3 layers of tissues; the tunica adventitia which covers the outside, the tunica media which is the middle layer and the tunica intima endothelium which is the inner layer. The diameters of the coronary arteries range from 0.6mm-4.4mm, any blockage to any of these arteries that stops blood flow to the affected area lead to coronary artery disease (CAD).       The normal blood glucose range is 4-6 mmol/L and 7.8mmol/L 2 hours after meal. This range is controlled by insulin which causes cells to absorb excess glucose in blood and glucagon which causes cells to release glucose from stores. Insulin is produced by the beta cells of the islets of Langerhans of the pancreas. When blood glucose level rises above its normal range insulin binds to the extracellular subunits of its receptors (IRS-1 and IRS-2) on the cell surface which sends signals into the cell causing the intracellular proteins to alter their activity which in turn initiates the movement of glucose transporters (GLU1-4, depending on the cell/tissues involved) to the cell membrane which then transports glucose into the cell where it may be further be converted glycogen, the storage form of glucose. Any impairment to the function of insulin, or its receptors lead to hyperglycemia and when excess of this glucose in bloodstream is passed in urine it results to diabetes mellitus. Diabe tes mellitus can be classified into two main types; Diabetes mellitus type 1 (DM 1) and diabetes mellitus type 2 (DM 2). High sugar levels in blood (hyperglycemia) maybe due to insulin resistance in cases of type 2 diabetes or destruction of beta cells of the pancreas in cases of type 1 diabetes, which downstream leads to CAD. Atherosclerosis which can occur in any part of the body result from endothelia damage which can be caused by high blood pressure, smoking, genetics, age, gender, high blood glucose, weight gain etc. when atherosclerosis occurs in any of the coronary arteries it leads to coronary artery disease. Events leading to atherosclerosis include; Endothelial damage which leads to inflammatory responses such as accumulation of white blood cells , low density lipoprotein (LDL)and high density lipoprotein (HDL), oxidation of LDL induced by free radicals (reactive oxygen species), platelet aggregation, chemotaxis of macrophages, formation of foam cells, proliferation of smooth muscle cells (atheroma occurs), fibrous tissue and calcium salts cause the atheroma to harden this results in less elasticity of the artery (atherosclerosis). All of these events narrow the coronary artery from the normal physiological range of 0.6-4.4mm (including small coronary arteries branching from the main arteries) to very smaller diameter depending on the level of narrowing and then eventual blockage preventing or limiting blood and nutrient supply to heart tissues leading to death of affected heart tissues, heart attack or even death of the patient. According to statistics, diabetes and coronary artery disease are closely related, this is because 50% of patients with diabetes are at risk of suffering CAD alongside. In the United States 77% cause of death is diabetic CAD. The prevalence of diabetes globally is increasing and its the major risk factor of other health conditions. The National Institute of Health reported that 65% of diabetic patients are more at risk of developing stroke, high blood pressure, obesity, kidney failure, and heart diseases such as cardiac arrest, myocardial infarction, and atherosclerosis in the heart (CAD) which when not optimally managed could lead to death. CAD and Diabetes Mellitus The cause of DM1 is unknown but studies say it could be genetic or viral infection which leads to an autoimmune condition where the body defense mechanism destroys its cells, in this case the pancreatic beta cells where insulin is produced. When the beta cells of the pancreas are destroyed, the pancreas will no longer be able to make insulin which downstream causes the bloodstream to be glucose logged due to inability of the body cells to move glucose out of the bloodstream, leading to impaired insulin secretion, decreased signalling in the hypothalamus, increased food intake, weight gain and hyperglycemia, which downstream leads to atherosclerosis. DM 2 is due to the body cells inability to respond to insulin stimulation. Insulin resistance is due to obesity, age and sedentary life style (irregular body activities), Age and sedentary lifestyle both lead up to increase in body weight (accumulation of adipose tissue). With or without hyperglycemia, insulin resistance can cause atherosclerosis, this results from increased lipolysis of adipocytes leading to increased nonesterified fatty acid secretion (NEFA), pro-inflammatory cytokines such as tumour P1521598x necrosis factor-a (TNF-a), interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1). NEFA can be deposited in and cause dysfunction of pancreatic beta cells, liver and skeletal muscles, all of which enhance insulin resistance and reduce production of insulin. Accumulation of NEFA in skeletal muscle leads to competition with glucose for substrate oxidation thereby increasing the intracellular content of fatty acid metabolites such as diacylglycerol (DAG), fatty acyl coenzyme A and ceremide which together activate serine/threonine kinase processes leading to insulin receptor substrate 1and 2 (IRS 1 IRS 2) phosphorylation, reducing their ability to undergo tyrosine phosphorylation and carry out their normal physiological function in insulin signalling. The final target of these receptors is the blockage of phosphatidylinositol 3-kinase (PI3) which is responsible for decreasing expression of adherent molecules, NF-kb activation, Ros formation and increasing eNOS production. PI3 blockade leads to hyperstimulation of mitogen-activated protein kinase (MAP-kinase) by increasing insulin production which contributes to vascular hypertrophy, hypertension, increased plasminogen activator inhibitor-1 (PAI-1) production and arrhythmias, all of these processes lead to endothelial lining damage which causes atherosclerosis. Diabetes and Atherosclerosis Hyperglycemia can also lead this atherosclerosis because increase in blood glucose levels leads to increase in reactive oxygen species (ROS) because of mitochondrial dysfunction which is the initial event observed in hyperglycemia. Glycolysis generates nicotinamide adenine dinucleotide (NADH) and pyruvate. Pyruvate in tricarboxylic cycle (TCA) generates molecules  of CO2, 4 NADH and 1 FADH NADH and FADH are electron carriers/donors in the electron transport chain which is made up of 4 complexes, I-IV). In mitochondria, NADH and FADH donate electron for generation of ATP. In hyperglycemia, there is increased glycolysis which leads to increased electron donation to the electron transfer chain (ETC) which increases electron flux raising voltage across the membrane and generates higher membrane potential eventually reaching a threshold where transport at complex III is blocked, increasing electron donation to O2 at complex III generating ROS, mostly superoxide (O-). Superoxide inactiva tes glycolytic enzymes glyceraldehyde 3-phosphate dehydrogenase which induces vascular injury via 4 main pathways; protein kinase C pathway, hexosamine pathway, advanced glycation endproducts and polyol pathway. ROS enhances atherosclerosis by blocking eNOS synthase which enhances production of other ROS especially in endothelial cells and vascular muscle cells. Superoxide reacts with nitric oxide to form peroxynitrite which selectively inhibits prostacyclin (PGI2) disrupting its synthases iron-thiolate centre. PGI2 inhibition causes build-up of its precursor prostaglandin endoperoxide (PGH2) which induces vasoconstriction and endothelial dysfunction. In addition, PGH2 promotes the conversion of PGI2 to thromboxane A2 by thromboxane synthase which leads to platelet aggregation. Diabetes and Response to injury Endothelial progenitor cells (EPC) and vascular endothelial growth factor (VEGF) are responsible for response to injury and hypoxia, both are lacking in diabetes, this makes repair of injury very slow enhancing atherosclerosis. Conclusion   Ã‚   With or without hyperglycemia, DM leads to atherosclerosis which if it happened in the coronary artery lead to narrowing and eventual blockage of the coronary artery leading to CAD. In DM 1 it goes through hyperglycemia/mitochondrial dysfunction pathway whereas in DM 2 it goes through insulin resistance/lipolysis pathway even in slim individuals if there is unequal distribution of fat across the body, it interferes with insulins ability to suppress lipolysis leading to higher NEFA production. Whichever way, DM is likely to lead up to CAD (when atherosclerosis occurs in the coronary artery) and other diseases such as obesity, high blood pressure, kidney disease and heart attack. One thing that can be seen in the events leading up to CAD are positive feedback events, for example, ROS blocks eNOS synthase which enhances the production of more ROS.

Public Enemies: Book Review Essay

The author arranged the book in such a way where he would be able to simultaneously show the progress of the gangs in the so-called â€Å"public enemies† era. He also wrote what happened in every specific time period. He organized his writing by dates; he divided actions and development among the gangs into certain time spans. He mainly focused on the years between 1933 and 1936, were Bonnie & Clyde, the Dillinger gang, and other more was mainstream. Furthermore, the author’s goal towards this book was to give the reader a complete and broad overview of the FBI on the War on Crime history. His goal was to portray the whole story, after the FBI released all files all the cases in the late 1980s. There were three things that made me interested in this book. First, I was amazed by how determined these criminals was. They put thought and planning in all their robberies, which they usually end up succeeding at. Moreover, these are crimes that were implemented about 77 years ago. I also admire their nature. I could never imagine how much courage and will these crooks had in order to carry out their brutal risky heists. I especially enjoyed reading the parts where the Dillinger gang would rob banks quickly and efficiently. Then they would aggressively open fire on the police officers as they perform their getaway. They made the police seem too simple to deal with. Secondly, I was astonished by the loyalty of women back in those days. They didn’t care that their men were actually robbers and in some cases killers. Except for Bonnie Parker where she was a robber herself. They would care for their men, cover for them, and comfort them as much as they can. I found that amazing since these women don’t actually exist anymore in our present time of â€Å"equal-rights. Finally, I was mind blown by how John Dillinger managed to escape from prison twice, and in addition to that, he also freed his fellows from prison as well. The public enemies indeed did have things in common. Nearly all of them are actually European immigrants or offspring of European immigrant parents. All of them seem to be aggressive, dangerous, and trouble making since their youth. Lots of them have even been sent to prison at a very early age. Hence, the majority of the public enemies have already obtained a criminal record before they went on their large scale heists. Furthermore, they all relied on a few common things when it came to undergo a robbery. They all had planned their robberies and getaways. They also used the same technique of preparing a generous amount of powerful gun power to be used in case of a police encounter. They all did not have long lives either. Most of them were killed in their 30s. They have been able to dodge the police for so long mainly for two reasons. First of all, they were well supplied with lots of powerful weapons. This has always helped them even out with the police in a shoot out. The public enemies were also extremely violent and aggressive. In any encounter with the police they would open fire and start shooting vigorously and brutally and the police without thinking or hesitation. Thinking and hesitation are two things the police did not lack, which always gave the crooks an edge. Secondly, they usually had planned their getaways through. Nearly all of them had even kidnapped innocent people, who were sometimes dragged along the shooting during the getaways to get a better chance of escape. Finally, they made sure they had good hiding spots, and they were also on the move continuously. Eventually, the FBI and all cooperating law enforcement agencies had reached their limits of hesitation. They have decided to shoot at the crooks the second they show absolutely any sigh of resistance. Obviously, there were lot of injuries and deaths. The FBI also decided to take the public enemies down once and for all by outnumbering them and engaging them at times were they are least prepared. For instance, they ambushed Bonnie and Clyde, and when the two lovers realized they were in danger they opened fire. But they were outnumbered and eventually killed by the police. Pretty Boy Floyd was killed in Ohio during a pursuit by local officers, and was shot dead by Melvin Purvis himself. The Dillinger Gang was hunted down one-by-one, and at the end killed John Dillinger after he got out of the movie theatre. Machine Gun Kelly was arrested in October 1933 and was poisoned for life. Baby Face Nelson was deeply wounded at the battle of the Barrington and died shortly after. Finally, Baker Karpis Gang was being hunted down and somehow split up. At the end Karpis was arrested in New Orleans and poisoned for life. And he was the last one on the public enemies list.

Introduced to a child Free Essays

When we first are Introduced to a child, we have to assess them to understand which bevel of language we are going to use with them, we would not say to a 6 month old baby, ‘Hello, how are you, what have you been doing today, what would you like for dinner et. We must use lots of facial expressions and soften our tone of voice and use shorter sentences, we tend to speak slower as well so we say ‘Hellos’ with a big smile on our face when speaking to a baby. If we are showing a baby something when we are speaking to them we should point also to help them understand what we are saying to them. We will write a custom essay sample on Introduced to a child or any similar topic only for you Order Now Rhetorical questions are not real questions as the person asking the question as such, also answer it, so we might say to a baby would you like your nap now, Oh yes you would, you look very tired’ or you would like your bottle of milk now, wouldn’t you’. It allows us to speak and communicate with a baby or toddler who will not answer our questions but it is a way of us using speech, language and communication on a daily basis, helping to be part of the day and feel involved. Using eye contact and smiling the response it usually positive and received back with a mile or babble. Closed questions should not be used all the time, only when a yes or no answer Is needed, we must ensure we still use all others areas through out the day, we can use a closed questions Like ‘have you finished your lunch’ ‘do you need help with your shoes’. Closed question should not be used on babies, but can be used on young even able to shake or nod their head. Sometimes if a child is upset or does not know you (their first settling in), closed questions can be used to help if the child is feeling anxious and does not want to hold a conversation with you, obviously this is something you do not want happening every day and the child should start to speak and say words to you. Open questions prompt a child to give a longer answer and are needed to develop their speech and language skills. So asking questions like ‘what shall we do today’ ‘what shall we have for lunch’. A child should not give a yes or no answer in open questions, but hopefully will speak up and answer the questions, sometimes you may et a ‘l don’t no’ answer, but that usually is due to others reasons. Babies will not be able to answer open questions and most of the time only children that feel comfortable with you, so the children that attend you setting for a while and are quite settled.
