What Is A Gene - 1446 Words

What is a gene? The word Gene derives from the Greek â€Å"genesis† (birth) or â€Å"genos† (origin) and was first coined by Wilhelm Johannsen in 1909. At that time, little or nothing was known about the existence of DNA, and the word gene was used to describe the Mendelian concept of a phenotypical trait that is transmitted through inheritance (Johansen, 1909). The gene as the fundamental unit of heredity is the original meaning of the word as first geneticists intended it. This essentially explains the reason why, during last century, a burst of research occurred in the genetic field: it was carried out in order to discover the genes responsible for the most various traits, from the ones causing diseases to the ones responsible for genetic variation across populations. In fact, the scientific community was convinced that genes retained all the crucial information necessary for organisms’ generation, growth, survival and reproduction (Sarkar, 1998). One of the fundamental discoveries of the 20th century was that DNA was the genetic code’s physical structure (Watson Crick, 1953) and, since then, many studies have disclosed the complicated pattern of regulation and expression of genes, which involve RNA synthesis and its subsequent translation into proteins. Nowadays, if we define genes from a physical/molecular point of view, we usually consider them as a specific sequence of DNA (and its control region), which is inheritable and codes for a product (Protein or RNA) that has aShow MoreRelatedWhat Are Genes And Genes?910 Words   |  4 Pages1.

The Pain In Osteoarthritis Health And Social Care Essay Free Essays

Osteoarthritis is a disease of the articulations, impacting 86 % of people over 65 ( Felson, Schaible 2009 ) . Patients with the status frequently complain of hurting within the joint, this hurting frequently worsens when weight bearing. Although, in advanced signifiers of the status there can be pain on remainder excessively. We will write a custom essay sample on The Pain In Osteoarthritis Health And Social Care Essay or any similar topic only for you Order Now Other ailments include progressive stiffness of the articulations and musculus failing ( Chu, Thornhill 2001 ) . Osteoarthritis is caused by loss of the articular gristle in articulations associated with hypertrophy of the bone and thickener of the capsule ( Enohumah, Imarengiaye 2008 ) . A articulation is where two castanetss, covered in articular gristle meet ; the articulation is lubricated with synovial fluid. Figure 1 shows the anatomy of a healthy articulation. Cartilage plays an of import function in leting smooth clash free motion of the joint. If the gristle becomes damaged motion is restricted and pain develops. Bone has an first-class capacity to mend itself nevertheless in degenerative arthritis the castanetss ability to mend itself consequences in chronic hurting. This is because as tissues try to mend, re-growth occurs abnormally doing some countries of bone to go dilutant and others thicker. This means that the two castanetss no-longer fit together every bit good, doi ng motion to go progressively hard and painful. If there was greater apprehension of the mechanisms behind the development of hurting, and why some patients with similar X raies appear to hold different sums of hurting more effectual interventions could be developed. This could pro-long the clip before the patient requires. This essay will look at how hurting is transmitted through the organic structure, the anatomy of articulations and how debasement of the joint can take to trouble in degenerative arthritis to let for the development of effectual interventions. This image shows the anatomy of a articulatio genus articulation and the accessary constituents of the joint that enable the joint to execute its map of clash free comfy motion. It is these constituents that can deteriorate in degenerative arthritis and cause hurting to develop. Although the image is of a articulatio genus articulation all articulations have a similar construction. ( Image taken from Enohumah and Imarengiaye. 2010 ) Figure 1: Diagram to Show the Anatomy of a Knee Joint. Pain is termed as an unpleasant sensory and emotional experience associated with tissue harm ( Merskey, Bogduk 1994 ) and a defense mechanism mechanism associating to weave harm ( Dray, Read 2007 ) . Pain can be described as transient ; this is the direct stimulation of nociceptive centripetal neurones and the ague hurting this causes. Pain of articulations can be chronic ; uninterrupted hurting which makes mundane undertakings progressively hard to set about. Chronic hurting is of small importance as does non mean tissue harm and may go on after the tissue has repaired ( Dray, Read 2007 ) . The hurting can besides be episodic ; this is when hurting intensifies when set abouting undertakings that require increased joint motion or strength, such as mounting stepss or bending over. This hurting can do psychological hurt to the patient and diminish their quality of life as the hurting forces them to go sedentary and stray. Figure 2: The Pain Pathway in Humans This tract illustrates how hurting is transmitted from the stimulation ( in degenerative arthritis this is a joint ) to the encephalon it besides lists some of the chemicals that can be released from damaged cells that affect hurting transmittal and esthesis ( Image taken from Srivastava, 2010 ) . Pain is transmitted form articulations to the encephalon via neurones with bare nervus terminations, see Figure 2. These constructions are known as nociceptors and the functional nociceptive unit is made up of capillaries, nociceptor and mast cell. Joints are innervated by both centripetal and sympathetic nervousnesss. Nociceptors are normally less than 5AÂ µm in diameter and either Type III myelinated with unmyelinated terminations or Type IV unmyelinated. They have a high threshold of activation which means that a larger depolarizing stimulus than normal is required to do activation. The high threshold enables neurones to go selective for noxious mechanical stimulation ( Enohumah, Imarengiaye 2008 ) . The stimulation can be interpreted as dynamic ( motion ) or inactive ( place feeling ) ( McDougall 2006 ) . Pain transmittal is as follows ; the nociceptors are stimulated and primary sensory nerve fibers which fire action potencies doing the release of substance P ( a peptide which increases hurting by leting the spinal nociceptors to be easy stimulated ) ( Enohumah, Imarengiaye 2008 ) . This activates cells in the dorsal horn of the spinal cord where they synapse with spinal neurones and transmit nervus urge to the mesencephalon and cerebral mantle. Chemical go-betweens such as prostaglandins and leukotrienes can be released from the site of tissue harm ensuing in peripheral nociceptor sensitisation ; this is the progressive elaboration of a response followed by perennial disposals of a stimulation. Pain felt in degenerative arthritis can be accounted for by the presence of ‘silent nociceptors ‘ which in a healthy person are non activated by a stimulation. These receptors can go activated following tissue harm or redness ( Felson, Schaible 2009 ) . This means that for person who is already sing an increased sum of hurting the activation of these receptors enhances the grade of hurting felt. Pain can besides be accounted for by peripheral sensitisation caused by a lessening in the activation threshold of nociceptors and afferent neurones, doing them to go hyper-responsive to both normal and noxious types of motion. If nociceptors are more sensitive to motion this besides contributes to both allodynia and hyperalgesia as motion becomes more painful. Two squads of research scientists Coggeshall ( 1983 ) and his colleagues and Schaible and Schmidt ( 1986 ) illustrated that the injection of china clay and carrageenin could do synovitis ; the redness of the synovial membrane, by take downing the activation threshold of type III and type IV nociceptors in articulatio genus articulations. By take downing the activation threshold they made it easier to excite the nociceptors, increasing the figure of action potencies produced per unit clip for noxious and innocuous stimulations, doing hurting. Decreasing the activation threshold and the activation of soundless receptors together increases the hurting felt by degenerative arthritis patients ( McDougall 2006 ) . This suggests that if it was possible to increase the threshold of nociceptors, hurting signalling would be decreased ; this is an thought for possible interventions in the hereafter. A farther proposal for the hurting felt in degenerative arthritis is an addition in intra-articular force per unit area ; the human articulatio genus contains synovial fluid within the joint. After hurt or on redness ( see Figure 3 ) the plasma membrane of blood vass becomes progressively leaky and allows plasma proteins to go forth the vasculature and come in the intra-articular infinite. This causes a alteration in the starling forces which allows fluid to flux into the joint causation localised hydrops, ‘excessive accretion of fluid in the organic structure tissues ‘ ( Oxford Concise Medical Dictionary 2007 ) . This Results in the puffiness of the joint increasing the intra-articular force per unit area, doing hurting within the joint, due to an addition in unstable energizing nociceptors. Figure 3: Illustration of How a Number of Chemicals and Neuropeptides Work Together to Cause Pain, Inflammation and Joint Degradation. The figure above shows how, Iinterleukin-1 ( IL-1 ) , interleukin-6 ( IL-6 ) , and tumour mortification factor ( TNF ) are illustrations of proinflammatory cytokines and direct the matrix metalloproteinase ( MMPs ) to degrade connective tissue. MMPs degrade the connective tissue that make up joint tissues. The loss of joint infinite that develops in degenerative arthritis is due to the activity of the MMPs. Growth factors ( VEGF ) can besides hold a infective function in Osteoarthritis. VEGF promotes the development of blood vass to let tissue growing. Research suggests that VEGF is involved in degenerative arthritis. Blood vas growing is accompanied by an increased nervus supply taking to increased hurting. The chondrocyte produces inordinate free groups that assist in the devastation of the environing joint tissue. Free groups are non pictured above ( Sharif et al. 2000 ) , ( Image taken from: Bonnet, Walsh redness. 2005 ) . To forestall tissue harm to articulations the organic structure has a protective mechanism to halt over extension or flexure of articulations, the joint senses the possible harm and releases hurting signals which prevent farther motion of the joint. In degenerative arthritis this protective mechanism is hyperactive and hurting is felt when the articulation is moved within the normal scope. Recent grounds suggests that osteoarthritic hurting is therefore ; joint motion creates emphasis on the axolemma of the ‘free ‘ nervus terminations, ensuing in the gap of mechanogated ion channels, the inflow of Na ions causes depolarization within the neurone and consequences in an action potency ( See Figure 2 ) . Mechanoreceptors are located in the Type III and IV sensory nerve nervus fibers, these channels have been discovered in articulatio genus articulation sensory nerves by electrophysiology measurings and supply an penetration into the physiological mechanisms which are respons ible for mechanotransduction in articulations ( McDougall 2006 ) . These receptors cause increased ionic conductance and cellular depolarisation, doing an action potency and the hurting esthesis ( Heppelmann, McDougall 2005 ) . To understand hurting in degenerative arthritis it is of import to set up where the hurting originates ( See Figure 4 ) . Cartilage is aneural and avascular so pain must arise from other constructions of the joint ( Felson 2001 ) . Possibly the subchondral bone, which is extremely innervated with postganglionic neurones, or the periosteum, synovial membrane, ligaments or the nervus capsule, All of which have nociceptors, maintain vascular tone, permeableness and bone homeostasis ( Dray, Read 2007 ) , any harm to these countries could do hurting. When articular gristle re-modelling occurs there is compaction of soft tissue and microfilaments in the subchondral bone. There is besides gush and cramp of musculuss environing the joint which could explicate the beginning of hurting in degenerative arthritis ( Enohumah, Imarengiaye 2008 ) . Figure 4: Diagram to Show Causes of Pain and Pain Transmission in Osteoarthritis. T This figure shows how a figure of factors influence hurting in degenerative arthritis some of these are mechanical factors ( MF ) others involve enzymes and biochemical tracts. The diagram besides shows how some factors could be used to increased gristle grows, a possible intervention for degenerative arthritis. ( Image taken from hypertext transfer protocol: //www.fortehealthcare.com/Cartrophen/technical % 20brochure.html ) As mentioned the articulation is made up of a figure of constructions of articulations ( See Figure 1 ) each of which can deteriorate and do hurting during degenerative arthritis ( See Figure 5 ) . First, the subchondrial bone this is a bed of bone below the gristle. During degenerative arthritis blood flow is increased to this country leting subchondrial cysts to develop. This build up of fluid in the bone causes a force per unit area addition, the addition in force per unit area pushes against the bone and activates noticepters which transmit hurting signals. Changes to the capsule and synovial membrane can besides do hurting ; redness occurs which consequences in an increased volume of fluid, increasing the sum of force per unit area on the joint which causes hurting. The sinews and Bursa can go inflamed and cause, tendonitis and bursitis which causes hurting and decreases the scope of motion of the joint. Muscle blowing and failing besides occur which restrict motion, the deficie ncy of willingness to exert can do musculus and ligament wasting which can do hurting ( Enohumah, Imarengiaye 2008 ) . As unexercised musculuss become weak and less able to set about strenuous undertakings this can go on to anyone but is more likely in a patient with degenerative arthritis and although this does non straight do hurting, musculus failing does increase hurting. This diagram illustrates that the joint border lessenings and the synovial fluid volume lessening in patients with degenerative arthritis. The Cartilage besides thins. The decrease in joint infinite, synovial fluid volume and cut gristle causes castanetss to rub against each other on motion doing hurting. ( Image adapted from hypertext transfer protocol: //www.mobilitychoices.co.uk/glossarypage.php? uid=46 A ; start=A ) Figure 5: Comparison of the Anatomical Features of a Joint with Osteoarthritis and a Joint of a Healthy Individual. The softening and cutting of gristle can be seen when imaging a joint with degenerative arthritis as there are cavities, it appears unsmooth, and has lesions in the gristle. This causes the gristle to go prone to splitting. This is a secondary cause of hurting in degenerative arthritis as it can take to interrupt castanetss, soft tissue harm and breaks which in bend all cause hurting signals to be transmitted to the encephalon. The organic structure attempts to mend this harm by originating bone re-growth the growing occurs unevenly and causes hurting. A lessening in the joint border and the decrease in volume of synovial fluid cause bone to rub against bone in an Osteoarthritis patient. In a healthy person this does non happen due to the presence of synovial fluid, leting clash free motion ( See Figure 5 ) . The stiffness of the new gristle makes the joint less able to absorb daze, doing motion painful. Osteoarthritis patients frequently complain of hurting non merely when traveling but besides when resting this can be explained by looking at the redness of articulations frequently associated with degenerative arthritis. When a articulation is inflamed a lessening in the hurting threshold consequences, this means that hurting signals that would usually travel unnoticed are transmitted via nociceptors to the encephalon. This is known as allodynia where hurting is felt for a usually innocuous stimulation ( McDougall 2006 ) such as sitting down or walking and hyperalgesia where increased hurting is experienced during an activity. An account for the disagreements between joint harm seen on X raies and joint hurting could be explained by looking at the two hurting transmittal tracts, the sidelong and medinal systems ( for hurting transmittal See Figure 2 ) . The thalamus and cerebral mantle are the countries of the encephalon that are involved in having and covering with hurting signals. The sidelong system, involves the stimulation of thalamic karyon in the ventral sidelong thalamus. The information is transmitted to the somatosensory cerebral mantle for analysis of location, continuance, strength and vicinity. The median system uses the midplane and intralaminar thalamic karyon to convey urges to different parts of the encephalon including the amygala to do affectional responses, attending and acquisition. The country of the encephalon urges are directed to change the hurting felt. If one system is stronger or more prevailing in some patients than others this could impact the sum and type of hurting felt and the class of intervention ( Hunter 2009 ) . Pain experiences are alone and effected by life experiences and genetic sciences. For illustration, a individual ‘s assurance in their ability to set about a undertaking or motion will specify their success in the undertaking. A patient ‘s inclination to catastrophize, or to do the best of a state of affairs will alter the hurting experience. The more hurting anticipated the more hurting felt ( Hunter 2009 ) . Social factors such as if a patient has a supportive environment, if they are stressed, low in liquors or traveling through an emotionally hard experience affect the sum of hurting felt ( Felson, Schaible 2009 ) . Factors that influence hurting but may non hold a scientific or physiological ground are besides of import indexs for the cause of hurting. Physical activity can increase or diminish pain esthesis. An addition in hurting can be felt when exerting particularly flexing and weight lifting, others feel soft exercising decreases hurting. The footwear a patient wears high heels increase hurting as there is increased emphasis on the articulatio genus articulation, whereas supportive flat places tend to do less hurting ( Hunter 2009 ) . If the patient has a past hurt or an hurt occurs and eventually environmental factors some patient ‘s complain of increased hurting during cold and wet conditions with high force per unit areas than on all right just yearss. No scientific grounds has shown these factors to act upon hurting but many patients do see alterations in hurting that can non be explained by imaging or disease provinces ( Enohumah, Imarengiaye 2008 ) . Pain in degenerative arthritis is n’t merely cognitive but there is affectional hurting excessively, this means that many degenerative arthritis patients suffer from depression and anxiousness ( McDougall 2006 ) . This could be due to the deficiency of mobility doing many patients to experience stray. It is hence imperative that the hurting tracts in degenerative arthritis are understood to let the development of effectual interventions to better the quality of life of a patient. Osteoarthritis is characterised by hurting in the articulations on activity which is relieved on remainder, this is episodic hurting. Advanced degenerative arthritis is when hurting can besides be felt at remainder and at dark and is known as chronic hurting. The hurting normally occurs as decreased map of the joint, stiffness or gelling of the joint which is short lived and relieved after inaction. Pain is variable and great differences can be seen in the sensed hurting in patients with similar scans. Pain is transmitted from the site of hurt to the encephalon down specialised neurones know as nociceptors. Nociceptors have a high threshold and hence merely transmit noxious stimulations. Although cartilage re-growth can trip hurting, gristle is avascular and aneurla and therefore research is concentrated on looking at the other construction of the joint that could do hurting. A possible mark for drug action is on the neuropeptides which can heighten the hurting felt by a patient when traveling the joint. Another cause of hurting is ; redness doing a lessening in the hurting threshold and the activation of soundless receptors. A ground for the disagreements between imaging of the joint and the hurting felt could be explained by looking at the two chief tracts of hurting transmittal the sidelong and medinal tracts. These tracts transmit signals to different countries of the encephalon and hence do a different experience of hurting, if these tracts were better understood they could be countries for drug intervention. Pain and redness are linked and hence interventions that relieve the symptoms of the disease may besides better the earnestness of the status. Finally, hurting can besides hold a cognitive cause this is where the patient uses past experiences and the environment to judge the hurting felt. If a patient was more comfy, less stressed, happier and in more agreeable conditions they may see a decrease in hurting despite no alteration in the disease province . This nevertheless is a complex physiological state of affairs and requires more research before it can be used in clinical scenes to cut down hurting. Another possible intervention could be to increase the hurting threshold this would do it harder to originate an action potency and the patient would be able to travel the joint more before hurting was felt. Before advanced and effectual interventions for degenerative arthritis are to be developed it is indispensable that more research on hurting transmittal and causes is undertaken.
