Olivopontocerebellar Atrophy Essay -- Biology Biological Essays

Olivopontocerebellar Atrophy Olivopontocerebellar atrophy (OPCA) was first described in 1900 by Dejerine and Thomas. OPCA is a group of dominant inheritance and sporadic neurological disorders characterized by a chronic, progressive, cerebellar ataxia that begins in middle age. The cerebellum and its connections are the primary sites of the disease in chronic progressive disorders that often occur in familial or hereditary patterns. Postmortem studies indicate an atrophy of the cerebellum, pons, and inferior olives. This neuropathological neuronal cell loss permits classification of OPCA as a non-Alzheimer’s neurodegenerative illness. Gross postmortem inspection of the brains of patients with OPCA shows marked shrinkage of the ventral half of the pons, and disappearance of the olivary eminence on the ventral surface of the medulla. These brains also exhibit an atrophy of the cerebellum with degeneration of the middle cerebellar peduncles, and to a lesser extent, of the inferior peduncles. Thus, the cerebellum suffers mainly through atrophy of its afferent fibers. The neocerebellum and the olive undergo the primary degeneration. The purkinje cells of the cerebellar cortex are affected secondarily. Histological examination shows severe degeneration of Purkinje cells, reduction in the number of cells in the molecular and granular layers of the cerebellar cortex, severe loss of the number of cells in the pontine nuclei and olives, and demyelination of the middle cerebellar peduncle. The cerebellar nuclei are well preserved. The tegmentum of the pons, the corticospinal tracts, and the restiform body are also usually unaffected.

U.S. Constitution Article I, Section 9 What It Means

Article 1, Section 9 of the U.S. Constitution places limits on the powers of Congress, the Legislative Branch. These restrictions include those on limiting the slave trade, suspending civil and legal protections of citizens, apportionment of direct taxes, and granting titles of nobility. It also prevents government employees and officials from accepting foreign gifts and titles, known as emoluments. Article I - The Legislative Branch - Section 9 Clause 1, Importation of Slaves Clause 1: The Migration or Importation of such Persons as any of the States now existing shall think proper to admit, shall not be prohibited by the Congress prior to the Year one thousand eight hundred and eight, but a Tax or duty may be imposed on such Importation, not exceeding ten dollars for each Person. Explanation: This clause relates to the slave trade. It prevented Congress from restricting the importation of slaves before 1808. It did allow Congress to levy a duty of up to 10 dollars for each slave. In 1807, the international slave trade was blocked and no more slaves were allowed to be imported legally into the United States. Slavery was still legal, however, within the United States until the end of the Civil War and the passage of the 13th Amendment in 1865. Clause 2, Habeas Corpus Clause 2: The Privilege of the Writ of Habeas Corpus shall not be suspended, unless when in Cases of Rebellion or Invasion the public Safety may require it. Explanation:  Habeas corpus is the right to be held in jail only if there are specific, legitimate charges filed against you in court. A person cant be detained indefinitely without legal process. This was suspended during the Civil War and for detainees in the War on Terror held at Guantanamo Bay. Clause 3, Bills of Attainder and Ex Post Facto Laws Clause 3: No Bill of Attainder or ex post facto Law shall be passed. Explanation: A bill of attainder is a way that a legislature acts as a judge and jury, declaring that a person or group of people are guilty of a crime and stating the punishment. An ex post facto law criminalizes acts retroactively, allowing people to be prosecuted for acts that werent illegal at the time they did them. Clause 4-7, Taxes and Congressional Spending Clause 4: No Capitation, or other direct, Tax shall be laid, unless in Proportion to the Census or Enumeration herein before directed to be taken. Clause 5: No Tax or Duty shall be laid on Articles exported from any State. Clause 6: No Preference shall be given by any Regulation of Commerce or Revenue to the Ports of one State over those of another: nor shall Vessels bound to, or from, one State, be obliged to enter, clear, or pay Duties in another. Clause 7: No Money shall be drawn from the Treasury, but in Consequence of Appropriations made by Law; and a regular Statement and Account of the Receipts and Expenditures of all public Money shall be published from time to time. Explanation:  These clauses set limits on how taxes can be levied. Originally, an income tax would not have been allowed, but this was authorized by the 16th Amendment in 1913. These clauses prevent taxes from being levied on trade between states. Congress must pass tax legislation to spend the public money and they must show how they have spent the money. Clause 8, Titles of Nobility and Emoluments Clause 8: No Title of Nobility shall be granted by the United States: And no Person holding any Office of Profit or Trust under them, shall, without the Consent of the Congress, accept of any present, Emolument, Office, or Title, of any kind whatever, from any King, Prince, or foreign State. Explanation:  Congress cant make you a Duke, Earl, or even a Marquis. If you are a civil servant or elected official, you cant accept anything from a foreign government or official, including an honorary title or an office. This clause prevents any government official from receiving foreign gifts without the permission of Congress. What are Emoluments? Clause 8, the so-called â€Å"Emoluments Clause,† specifies that no elected or appointed U.S. government official—including the president of the United States—may accept payments from foreign governments during their terms in office. The Merriam-Webster Dictionary defines emoluments as â€Å"returns arising from office or employment usually in the form of compensation or perquisites.† Constitutional scholars suggest the Emoluments Clause was added to prevent American ambassadors of the 1700s, living abroad from being influenced or corrupted by gifts from wealthy European powers. Past examples of violations of the Emoluments Clause by some of America’s Founding Fathers include Benjamin Franklin’s acceptance of diamond-covered snuffbox from the King of France and John Jay’s acceptance of a purebred stallion from the King of Spain.

How to Manage and ID Japanese Maple

Japanese maple is one of the most versatile trees for any yard, patio, or garden. Often grown for its unique 7-palmed green or red colored leaf, the maple also has an interesting growth habit, with a fine leaf texture and muscular-looking multiple trunks. Japanese maples have extraordinary fall colors that range from bright yellow through orange and red, and is often striking, even on trees grown in total shade. Specifics Scientific name: Acer palmatum Pronunciation: AY-ser pal-MAY-tum Family: Aceraceae USDA hardiness zones: USDA hardiness zones: 5B through 8 Origin: not native to North America Uses: Bonsai; container or above-ground planter; near a deck or patio; trainable as a standard; specimen Availability: generally available in many areas within its hardiness range Physical Description Height: 15 to 25 feet Spread: 15 to 25 feet Crown uniformity: symmetrical  canopy  with a regular (or smooth)  outline  and individuals have more or less identical crown forms Crown shape: round; vase shape Crown density: moderate Growth rate: slow Texture: medium Foliage Descriptions Leaf arrangement: opposite/subopposite Leaf type: simple Leaf margin: lobed; serrate Leaf shape: star-shaped Leaf venation: palmate Leaf type and persistence: deciduous Leaf blade length: 2 to 4 inches Leaf color: green Fall color: copper; orange; red; yellow Fall characteristic: showy Popular Maple Cultivars There are many cultivars of Japanese maple with a wide variety of leaf shapes and color, growth habits, and sizes. Here are some of the most popular: Atropurpureum - has reddish leaves with only five lobes  Bloodgood - new foliage is bright red, some leaves darkening to a dim green  Burgundy Lace - reddish foliage with cut leaf (sinus nearly down to the petiole)Dissectum - finely dissected leaves in green or red, growing 10 to 12 feet tall  Elegans - leaves with rose-colored margins when they first unfold  Ornatum - leaf is beautifully cut and reddish Trunk and Branch Descriptions Trunk/bark/branches: bark is thin and easily damaged from mechanical impact; droop as the tree grows, and will require pruning for vehicular or pedestrian clearance beneath the canopy; routinely grown with, or trainable to be grown with, multiple trunks; showy trunk; no thorns Pruning requirement: requires pruning to develop a strong structure Breakage: resistant Current year twig color: green; reddish Current year twig thickness: thin Pruning a Maple Most maples, if in good health and free to grow, need very little pruning. Only train for developing a leading (or multiple) shoot(s) which will eventually establish the trees framework. Maples should not be pruned in spring and could bleed profusely. Wait to prune until late summer to early autumn and only on a young tree. A habit should be encouraged in which the branches develop low and grow up at sharp angles. If suckering of green-leaved root stock occurs below the graft line on your red-leafed grafted variety, remove the green sprout immediately. Japanese Maple Culture Light requirements: tree grows best in part shade/part sun but can also handle the shade. Soil tolerances: clay; loam; sand; slightly alkaline; acidic; well-drained Drought tolerance: moderate Aerosol salt tolerance: none Soil salt tolerance: moderate Common Pests Aphids can infest Japanese maples and heavy populations can cause leaf drop or a dripping of honeydew. Scales can be a problem. Neither insect will cause the tree to die. If borers become active, it probably means you have an already sick tree. Keep the tree healthy. Leaf scorch  may become a problem during periods of high temperatures accompanied by wind. Planting Japanese maple in a bit of shade will help. Keep trees well-watered during dry periods. Symptoms of scorch and drought are tan dead areas on foliage. Bottom Line The growing habit of a Japanese maple varies widely depending on cultivar. From globose (round or spherical form) branching to the ground, to upright to vase-shaped, the maple is always a delight to look at. The globose selections look best when they are allowed to branch to the ground. Be sure to clear all turf away from beneath the branches of these low growing types so the lawn mower will not damage the tree. The more upright selections make a nice patio or small shade trees for residential lots. A large selection or compact cultivars make wonderful accents for any landscape. Japanese maple tends to leaf out early, so it may be injured by spring frosts. Protect them from drying winds and direct sun by providing exposure to partial or filtered shade and well-drained, acid soil with plenty of organic matter, particularly in the southern part of its range. Leaves often scorch in hot summer weather in USDA hardiness zones 7b and 8, unless they are in some shade or irrigated during dry weather. More direct sun can be tolerated in the northern part of the range. Be sure drainage is maintained and never allow water to stand around the roots. The tree grows fine on clay soils as long as the ground is sloped so water does not accumulate in the soil. It responds well to several inches of mulch placed beneath the canopy.

Chasing Zero Essay - 1065 Words

Chasing Zero is a documentary which was meant to both educate the viewer on the prevalence of medical harm as well as to enlighten both the public and health care providers on the preventability of these events (Discovery, 2010). The documentary expounded on the fact each year more people die each year from a preventable medical error than die due to breast cancer, motor vehicle accidents or AIDS (Institute of Medicine, 1999). Medical harm can result from adverse drug events, surgical injuries, wrong-site surgery, suicides, restraint-related injuries, falls, burns, pressure ulcers and mistaken patient identities (Institute of Medicine, 1999). Incidences of medical error have been reported in the media for many years. The most startling†¦show more content†¦One of the most critical factors which contribute to the number of preventable cases of healthcare harm is the culture of silence surrounding these cases. The fear of medical providers to report incidences is related to the possibility of punishment and liability due to a medical error (Discovery, 2010). The criminalization of some acts of medical error has resulted in job dismissal, criminal charges and jail time for some healthcare workers. This is despite the fact that the system they are working in helped to create the situation which led to the error in the first place. Human error, due to fatigue and system errors can result in deadly consequences, but by criminalizing the error it effectively shuts down the ability to correct the root problem. Healthcare workers, working at all levels within the medical system, can provide valuable input on how to improve the processes and prevent harm from occurring (Discovery, 2010). Healthcare workers are not the only ones fearful of exposing medical errors. The medical institutes themselves operate behind a wall of silence. The IOM first recommended a national medical error reporting system in 1999 and despite attempts by then President Clinton, the American Medical Association and the American Hospital Association successfully lobbied against it (Dyess, 2009). As of 2009, only 20 states have a mandatory medical error reporting system and only a fraction of estimatedShow MoreRelatedCrashing in a Back Door969 Words   |  4 Pagesextinguish those on fire as their flesh melted away regardless.

Advantages Disadvantages Of The Electric Car Written by Chris on 30 April 2010. Visited 107 times, 2 so far today In this article we take a look at the advantages and current (but improving) disadvantages of the Electric Car. With more and more car manufacturers making new Electric Cars, this is obviously the way forward for the future, but there is obviously a very long way to go. THE ADVANTAGES AND DISADVANTAGES OF THE ELECTRIC CAR Electric cars are not only cheaper and greener to run, but in the long term they will help with the problem the world is facing with running out of oil resources. THE DISADVANTAGES: * They are currently expensive to buy with some costing up to $50,000 * Short battery life (some have to recharge after only 100 miles) * The batteries take up a lot of space * lack of charging points in the community, although this is expected to improve in time * Recharging costs (although cheaper than liquid fuel) can put a sttain on your electricity bill * Recharging the battery can take anything from 1 hour and up to 8 hours * Some are considered to be too small Not an ideal family car, but again this is likely to improve over time * Some consider the designs to be â€Å"ugly† A NEW CONCEPT IDEA: A new concept to increase the cars travel compacity is to have two or more batteries installed, where you can switch to another battery when you start running out of charge. Then whilst you are running on a second battery, a dynamo can recharge your dead battery whilst you are driving. The problem with this is that the batteries would have to be made smaller to be able to fit nicely into the car. How to cite Andvantage and Disadvantage of Electrical Cars, Papers

Early Childhood Language Development-Free-Samples for Students

Question: Discuss about the Early Childhood Language Development. Answer: This essay talks about the strong links between childrens language development and cognitive reasons of their success in school achievements and how these are best facilitated within the social learning as stated by (Fielding-Barnsley Hay, 2012), it discuses about the external outside factors that manipulate them and the social sources which helps them achieve success in school and the outside world. It is very important to achieve the ability to talk for a child in their early childhood. Language is a tool that opens up many opportunities in the social world. Language development is very important in order to communicate and express their feelings and experience and needs.
