Medical Article Essays - Stem Cells, Cord Blood, Umbilical Cord

Medical Article December 21, 1999 The Hope, and Hype, of Cord Blood By DENISE GRADY Should parents pay a blood bank to store the blood from their newborn baby's umbilical cord and placenta, in case that child or another family member ever needs it to treat cancer or leukemia? Expectant parents are being urged to do so by companies that have sprung up during the past few years to sell cord-blood banking as a form of biological insurance against such dreaded diseases. The pitch is based on reports in medical journals, such as a major study published last week in the New England Journal of Medicine, showing that cord blood can sometimes be used in place of a bone marrow transplant. Like bone marrow, cord blood is rich in stem cells, which can churn out many different types of cells to rebuild a patient's blood supply and immune system after high doses of radiation and chemotherapy. And a patient's own cord blood, or that from a relative, is more likely than cord blood from an unrelated donor to be a good tissue match and to be accepted by the recipient's body. Some experts in bone-marrow transplantation and blood banking frown on the cord-blood business, arguing that people are being frightened into wasting money on a service they will probably never need. Moreover, private companies are growing in tandem with public banks, and some scientists worry that private banking will limit public access to cord blood. They are concerned because the cord blood in private banks remains the property of the donor family and is not available to patients seeking a compatible donor. But the companies say that however remote the possibility that the blood will be needed, people who choose to bank their own cord blood have a right to do so. In most cases their cord blood would be thrown away in the delivery room if they did not pay to bank it. There are only a few cord-blood banks in the United States, and most hospitals do not have specially trained staff members to collect the blood. Like bone marrow, cord blood must be matched to the recipient by tests for six inherited traits that determine an individual's tissue type. Cord blood does not have to be as precisely matched as bone marrow, but still, the closer the match, the better the odds of success. The weaker the match, the more likely it is that the recipient's body will reject the transplant, or the transplant will attack the recipient's tissues, in a life-threatening reaction called graft versus host disease. The companies that freeze cord blood and bank it point out that a person's own cord blood is a perfect match, and a sibling's cord blood a more likely match than a specimen from a stranger. And so, the argument goes, the best way to protect an entire family from the unthinkable is to save the newborns' cord blood. Promotional literature for one company, Cord Blood Registry, in San Bruno, Calif., emphasizes that people with cancer in the family may have a special interest in cord-blood banking, along with those who have the hardest time finding matches, which includes members of racial minorities, especially families in which the parents are of different races. According to a spokeswoman, Scoti Kaesshaefer, the company reaches parents-to-be by promoting itself to doctors, nurses and childbirth educators, and by leaving information at hospitals. Among the promotional materials the company provided to the New York Times were copies of articles from other newspapers suggesting that cancer among children is on the rise. The company also has a Web site and an 800 number with a recorded greeting that instructs callers to have their credit cards ready. The idea of saving one's own cord blood seems to be catching on. Cord Blood Registry, which describes itself as the largest private cord-blood banking firm in the United States, has stored 10,000 samples during the past three years: 1,500 in 1995, 3,000 in 1996 and 6,000 in 1997. The company charges an initial fee of $1,200 to collect a sample and freeze it, and then $95 a year to keep it stored in liquid nitrogen at the blood bank at the University of Arizona. Customers include people with perfectly healthy children, who just want extra peace of mind, as well as some families who have lost a child to leukemia or another disease and fear for the health of their other children. In its three

Top Tips for Doing College Homework

Top Tips for Doing College Homework In contrast to the academic requirements of high school, college courses present a much heavier, more consistent workload. And with everything else that college students have to manage jobs, personal life, relationships, physical health, cocurricular obligations it can sometimes seem like getting your homework done is an impossible feat. At the same time, however,  not  getting your work done is a recipe for disaster. So, what tips and tricks can you use to get your homework done in college? Tips for Successfully Doing College Homework Use these tips to create a process that works for you and your personal study style. Use a Time Management System Put all major assignments and their due dates in your time management system.  A key part of staying on top of your homework is knowing whats coming; no one, after all, wants to realize on Tuesday that they have a major midterm on Thursday. To avoid surprising yourself, make sure all of your major homework assignments and their due dates are documented in your calendar. That way, you wont inadvertently sabotage your own success simply because youve mismanaged your time. Schedule Homework Time Schedule times to do homework each week, and keep those appointments.  Without designated time for addressing your  to-dos, youre more likely to cram at the last minute, which adds to your anxiety levels. By putting homework on your calendar, youll have the time allocated in your already-too-busy schedule, youll reduce your stress by knowing when, exactly, your homework will be done, and youll be better able to enjoy whatever else you have planned since youll know your homework is already taken care of. Sneak in Your Homework Use small increments of time whenever possible.  You know that 20-minute bus ride you have to and from campus every day? Well, thats 40 minutes a day, 5 days a week which means that if you did some reading during the ride, youd get more than 3 hours of homework done during your commute. Those little increments can add up: 30 minutes between classes here, 10 minutes waiting for a friend there. Be smart about sneaking in small bits of homework so that you can conquer the bigger assignments piece by piece. You Cant Always Get It All Done Understand that you cant always get all your homework done.  One of the biggest skills to learn in college is how to gauge what you  cant  get done. Because sometimes, there really is only so many hours in a day, and the basic laws of physics mean you cant accomplish everything on your to-do list. If you just cant get all your homework done, make some smart decisions about how to choose what to do and what to leave behind. Are you doing great in one of your classes, and skipping the reading one week shouldnt hurt too much? Are you failing another and definitely need to focus your efforts there? Hit the Reset Button Dont get caught up in the get-caught-up trap.  If you fall behind on your homework, its easy to think and hope that youll be able to catch up. So youll set a plan to catch up, but the more you try to catch up, the more you fall behind. If youre falling behind on your reading and are feeling overwhelmed, give yourself permission to start anew. Figure out what you need to get done for your next assignment or class, and get it done. Its easier to cover the material you missed when youre studying for an exam in the future than it is to fall further and further behind right now. Use Your Resources Use class and other resources to help make doing your homework more productive and efficient.  You might, for example, think that you dont need to go to class because the professor only covers whats already been addressed in the reading. Not true. You should always go to class for a variety of reasons and doing so can make your homework load lighter. Youll better understand the material, be better able to absorb the work you do out of class, be better prepared for upcoming exams (thereby saving you studying time and improving your academic performance), and overall just have a better mastery of the material. Additionally, use your professors office hours or time in an academic support center to reinforce what youve learned through your homework assignments. Doing homework shouldnt just be a to-do item on your list; it should be an essential part of your college academic experience.

Seemingly, the hurricane itself and the collapse of the levees that protected the city were built below the sea level. These aspects made Katrina a more complex natural disaster to fight leading to industrial disaster, evacuation challenges, widespread of poisonous pollution, persistent flooding and unprecedented public concerns regarding human safety. The protection against the Katrina is reflected to start with the weather forecasting team early 2005. The meteorologists warned people surrounding the Gulf Coast region to evacuate the region. Additionally, the National Weather Service was concerned in that it warned people that after the storm the area will be uninhabitable hence it advised people for looking alternative places to reside until it was over. The protection efforts by the federal government were seen to be executed by the Federal Emergency Management Agency. People in the New Orleans were to evacuate and seek for new shelter. However, the government had allowed some of the population that could not leave the town immediately to occupy the Morial Complex. Jointly, FEMA officials and an emergency-preparedness contractor advised FEMA that the evacuation process was not effective as it lacked sufficient transportation for the large population. There are different techniques that FEMA and other relevant authorities adopted for the mitigation process for the Katrina Hurricane. For instance, the University of Mississippi adopted the radio-controlled warning systems that warned of the Tornado. FEMA addressed and initiated Diamondhead homes in the Coastal regions that could prevent the people from future floods and injuries. It included a reinforced and laminated beams along the ceilings enhanced the roofs’ capability to anchor themselves. After such an event, the constructions of the houses in the affected areas were subjected to the International Residential

Merger versus IPO or Acquisition Essay Example | Topics and Well Written Essays - 500 words

Merger versus IPO or Acquisition - Essay Example However, the company is bound by regulatory restrictions to seek prior permission to conduct this exercise; a permission that might be granted or otherwise rejected under strict terms of engagements. Another threat lies in the management of the many stocks. The company may get locked up in meeting the expectation of the public market both in the short term and into the unforeseeable future before embarking on a meaningful journey of expansion (Burton & Prasad, 1997). Kudler Fine Foods also has the option of expanding its operations through mergers or opting to acquire another firm within its line of operations. Noteworthy, these two options possess more or less similar opportunities and challenges. In fact, the special alchemy of a merger and/or an acquisition is that a combined effort is greater than the sum of individuals’ efforts (King, Slotegraaf & Kesner, 2008). Accordingly, it would be more valuable for Kudler Fine Foods to seek the services of another company than function as an individual entity. Merging with a company offering delivery services has the possibilities of giving Kudler Fine Foods a competitive advantage over other similar businesses in the market. Additionally, such a combined effort would set the company on a cost saving path related to the management of the delivery services of its food delicacies. Whichever option between a merger or an acquisition, the resultant company would give Kudler Company a synergetic com petitive strength to function efficiently and the capacity to acquire a greater market share with a re-doubled effect of generating more revenues. On the negative side, mergers and acquisition provide narrower market opportunities compared to an IPO. They are not only less efficient in market pricing, but they may also result into one or both parties losing vital control of key operational elements

Impact Event as a Cause for Mass Extinction

Impact Event as a Cause for Mass Extinction   By Tom Newell    Part A          Possible Triggers for Mass Extinction Origin of Trigger Explanation Impact Events Extra-terrestrial Impact events, proposed as causes of mass extinction, are when the planet is struck by a comet or meteor large enough to create a huge shockwave felt around the globe. Widespread dust and debris rain down as well as forming a dust cloud, disrupting the climate and causing extinction on a global, rather than a local, scale. Climate Change Atmospheric Earths climate is not constant. Over geological time, the Earths dominant climate has gone from ice age to tropical heat and from steamy jungles to searing deserts. When such climate change occurs abruptly either in the form of a global warming or cooling animals and plants have no time to adapt so mass extinctions can occur. Flood Basalt Eruptions Land Flood basalt eruptions are a type of large-scale volcanic activity, both in terms of extent and duration, that can occur on land or on the ocean floor. A flood basalt may continue to erupt for tens of thousands possibly millions of years and the lava can cover hundreds of thousands of kilometres. Catastrophic Methane Releases Atmospheric Methane clathrate is an ice-like substance formed from water and methane in the sea bed, arctic lakes and permafrost. A temperature rise causes the methane in the clathrate to be released as gas. Global warming results and causes further clathrate heating and methane release. The resultant soaring temperature causes such stress to plant and animal life that mass extinction follows. Humans Land Because of the industrial lives we live, we are constantly emitting pollutants into the atmosphere. The chemicals being emitted are changing the composition of the atmosphere. This intern changes how our atmosphere affects our lives, from controlling temperature to blocking cosmic radiation. Part B It is believed that an impact event has caused a mass extinction in the past. Whats to say it wont happen again? An impact event capable of causing a mass extinction is when the planet is struck by an asteroid or meteor large enough to create a huge shockwave felt around the globe. When an impact event happens, the gigantic amount of kinetic energy is partly transferred from the large asteroid or meteorite travelling at high speeds, into the Earth. The rest of the energy is converted into heat and sound, creating pressure waves travelling radially outwards from its centre, similar to that of an atomic bomb. (physics.org, n.d.) As well as the blast from the impact, enormous amounts of dust and debris can be kicked up into the atmosphere blocking out sunlight and preventing the process of photosynthesis in plants from occurring, massively affecting the balance of ecosystems. If humans on the other side of the world from where the asteroid hit, survived the initial impact, they would mo st likely be killed by fiery rocks raining down from the sky and the heavily polluted dust filled atmosphere. Because of the polluted air, humans will not be able to breath properly and the Earths temperature will increase immensely. The huge dust cloud formed would block out light from the sun. If the asteroid lands in the ocean a colossal tsunami will form wiping out everything in its path and potentially wrapping around the world. An extensive earthquake will also be felt all over the globe after the impact, which will send structures crashing down and habitats will be destroyed. Obviously this chain of events would destroy the systems that we depend on for survival, from economic and infrastructure to the biological and fundamental building blocks of life, therefore causing a mass extinction. Part C Our planet is currently in the midst of its 6th mass extinction and unlike past mass extinction, caused by events like asteroid strikes and volcanic eruptions, humans are to blame! (biologicaldiversity.org, n.d.) It is human activities such as the emission of carbon monoxide (CO) and the clearing of wildlife that are killing our planet. Considerable amounts of CO are being emitted into the atmosphere every day because of our industrial lifestyle, but most people dont realise the harm that is being done to the environment. CO can be released into the air via a multitude of ways, but most commonly through your cars exhaust and the burning of fossil fuels in factories. Once CO is in the atmosphere it takes an oxygen molecule from the ozone molecules contained in the ozone layer in the attempt to make itself carbon dioxide (CO2). In doing this the ozone layer is damaged, therefore affecting its ability to protect us from the suns rays. Therefore, global warming occurs and the Earth will eventually be heated to a temperature at which humans and hundreds of thousands of other lifeforms can no longer survive. Another way in which humans contribute to mass extinction is through habitat removal. Not only does the clearing of habitants destroy the homes of animals, leaving them without a suitable place to live, but it also increases the amount of CO2 in the air. Trees and plants play a critical role in the ecosystem. They absorb carbon dioxide in the atmosphere and convert it into oxygen for us to inhale and use in respiration. By clearing wildlife, we are reducing the amount of trees and plants therefore increasing the amount of CO2 in the atmosphere. Global warming is no myth and there is plenty of evidence to prove its existence. According to three reliable international agencies, 2016 was crowned the hottest year on record. (www.abc.net.au, 2017) This was no coincidence either, 2015 and 2014 have been the 2nd and 3rd hottest years to be recorded. This is clear evidence that we are impairing the ozone layer and putting our lives in danger and contributing to the next mass extinction. It is hard to deny that humans are causing the Earth to undergo its 6th mass extinction when there is so much evidence to suggest so. The real question isnt whether or not humans are currently causing the planets 6th mass extinction event, but whether or not we can do anything to stop it. Or is it already too late?
