Health Insurance

April 6, 2011 By admin

If you’re working to have your folks covered by a health insurance policy, you could be taking a look at a bunch of options for a method to best get everybody the cover they require. An individual healthcare insurance plan will do what you would expect, insure just one individual, by name. Often , there are 2 ways to go – individual health insurance policies or family health insurance policies. If you’ve got a huge family, what you want to have could be a no brainer – have family insurance that may cover you, your partner and all of the kids. Fifteen thousand on your family’s medical care insurance ( including your partner and kids ) and an extra Rs. Fifteen thousand for the hospital insurance of your mother and father.

Mediclaim insurance plans like Health Advantage And is one of its type, whereby you can present a policy to your mother and father and save tax. If you opt to present this policy, you’ll be entitled to a further tax saving quantity of Rs. Fifteen thousand. When you buy your global health insurance, take account of these other critical factors : Maximum lifetime coverage might be as high as $5,000,000 eighty / twenty co-insurance in the USA, and no co-insurance outside the United States PPO networks within the United States and approval of any doctor outside of the USA Deductibles that range all the way from $250 to $10,000 Medical Evacuation Coverage for prescription pharmaceuticals after the deductible is met Health plans that give you different furlough options The best information I can provide you with is to talk with an insurance broker about these different facets of your international health insurance. There could be real benefits that you may want but that will be excluded on your medical insurance coverage. Corporations always list the advantages in large print on their internet sites and leaflets.

There are 2 classes that cheap medicare plans fall in to. A good insurance broker will be in a position to help explain the schedule of benefits and exclusions. Essentially , and indemnity plan will be in a position to let you select the consultant. This is the indemnity plans and managed care plans or what you can describe as the HMOs or PPOs. This will also pay for your doctor’s bills in part, completely or up to a cited amount. World Student Travel Insurance can be considered speciality insurance and often not all insurance firms like Blue Cross and Aetna offer coverage. The monthly fee for World Student Travel healthcare insurance is reasonable – they typically go from $35 to $60 per month. The premium or the price of the plan is conditional upon the age of the insured, the policy maximum and the deductible option. Further coverage for sports activities can increase the premium. You can contact your varsity acknowledgments office to help identify the counseled plans.

Chromosome

Chromosome

A Chromosome (Greek – chromo – colour and soma – body) can be defined as a threadlike strand of DNA and protein located in individual cells. Put simply it is a mechanism for holding genes but contains a number of other elements, including regulatory and nucleotide sequences. These are all tightly packaged or coiled around proteins, which afford them structural support. Chromosomes exhibit considerable variation but all have an essential hereditary function to perform.   
                                                                                                                                                 
A single molecule of long chain DNA can consist of anything between 10,000 and 1,000,000 nucleotides. Those with a nuclei or Eukaryotic cells possess large linear chromosomes in a condensed structure called chromatin. Those without nuclei or Prokaryotic cells and viruses possess smaller circular genephores or linear chromosomes, sometimes accompanied by DNA molecules called plasmids. Numerous formats exist cells may even contain more than one type of chromosome.

Chromosomes constitute units fundamental to the success of cellular regeneration, and undergo replication and division for purposes of transmission. They are either duplicated (synthetically copied) and consist of two copies connected by a centromere or unduplicated, single linear strands. A Duplicated chromosome is compacted as part of the process of mitosis and meiosis giving rise to the familiar four arm shape.

Chromosomal recombination has an important function to fulfil in guaranteeing genetic diversity and the future survival of progeny. In every human cell, there are between 20,000 and 25,000 genes located on 46 chromosomes, which occur as 23 pairs, one from the mother and one from the father. If these structures fail due to instability and translocation, the cell may undergo mitotic disaster and die.

WHAT IS THE LONGEVITY GENE? DOES IT EXIST AND HOW DOES IT WORK?

March 16, 2011 By admin
Longevity Gene

Longevity Gene

The quest for eternal youth or an elixir of life has been the “holy grail” of modern medical science. This may now have been realised. Recent genetic research based on centenarians would tend to indicate that there is not a single longevity gene but a whole series of genes. These then work in tandem increasing an individual’s prospects of living into old age.

The correct combinations are clearly far from common since only one in every 10,000 people actually lives to 100. But among those who do it is likely that their DNA will contain a number of these genes. Carriers even if pursue a sedentary lifestyle a lack of exercise and a poor diet would appear to be protected against the worst ravages of time.

According to Eline Slagboom of Leiden University, they possess genes that stop diseases such as cancer or the aging process from being switched on. Their bodies seem to have a distinct means of metabolising fats and glucose and their skin remains supple. These factors are under genetic control hence longevity would appear to be hereditary.

The human genome contains some 28,000 genes, which are governed by a small number of “regulators.” ADIPOQ present in 10% of children but 30% of centenarians is one such a Methuselah or longevity gene. Others are thought to include CETP and ApoC3 present in 10% of children but in 20% of centenarians. Studies indicate that even small mutations can greatly increase a person’s lifespan.

Dr Nir Barzilai of Albert Einstein College of Medicine in New York is convinced that these discoveries will eventually lead to the development of drugs that delay the onset of age related illnesses.

WHAT IS MEDICAL GENETIC RESEARCH? WHY IS IT DONE AND HOW IS IT USED?

March 11, 2011 By admin

Medical genetics research involves the study of the nature and application of the role genes in hereditary and acquired illness. The benefits to be derived from such research are numerous and extensive. It can lead to the discovery and development of new diagnostic methods and therapies as well as contributing to the expansion of the knowledge base for affected families.

Medical genetics research encompasses a broad spectrum of subject matter and techniques whose importance is growing in relation to many familiar disorders. The focus has inevitably been on the big killers such as cancer, neurological degeneration and cardiovascular disease but much valuable work has also been done on lesser known conditions such as renal genetics.

We are witnessing a genetics revolution with the emergence of a host of new sub specialities: clinical, metabolic and biochemical, cytogenetics, molecular and mitochondrial. In practice medical genetic research involves conducting functional biological studies of the genes in healthy cells. This usually requires the generation and construction of complex computer models, conducting patient studies and collaborating with social scientists on impact assessments.         

DNA sequencing is just one technique in genetics available to analyse the genomic sequence of a given gene. Most of these tests are target specific, sensitive and can identify mutations. For instance Southern Blotting is quite a simple procedure used to diagnose medical disorders which are the result of trinucleotide repeats.     

The development of gene therapy as a method of treating disease constitutes an important spin off. It involves the alteration or modification of genes within human cells and tissues. They are commonly inserted into an “unspecified genomic location” with the objective of replacing those that are defective.

The initial concentration of effort was on illnesses linked to single -gene mutations, such as haemophilia and cystic fibrosis but met with mixed success. This has changed and the emphasis is now on carcinogenic diseases.

WHAT IS DNA? HOW CAN DNA BE USED? PATERNITY TESTING, TESTING FOR GENETIC ILLNESS

February 21, 2011 By admin

DNA or Deoxyribonucleic Acid is the genetic material that retains the detailed hereditary instructions essential to the growth and proper functioning of living organisms. It is generally not present as a single molecule but as a pair of molecules that are bound together, two long entwined strands or the iconic double helix. This code or blueprint is then interpreted and applied utilising several basic processes.

DNA is located in the overwhelming majority of cell nuclei and mitochondria and contains vital information (sequences called genes) for the creation of cell components as well as for structural and regulation purposes. Within cells it takes the form of chromosomes, long structures, which are duplicated or copied prior to cell division in a process known as DNA replication. When a cell needs a protein it does so through a process of transcription, the copying of stretches or sequences into the nucleic acid RNA.   

The nature and existence of DNA means that it can be readily put to practical use. There has been rapid expansion in recent years of DNA testing for paternity. The human contains an estimated 20,000-25,000 genes a person inherits two copies of every gene (except for sexual traits) one from each parent. Specific sequences are examined to see if they have been copied from either individual. A similar procedure is utilised in the acquisition of forensic evidence in criminal cases.

DNA testing for disease is looking for changes in chromosomes, genes or proteins. It focuses not only on missing and mutant forms of genes but also on biochemical substances. For example an individual with a mutation in BRCA1 has a 65% cumulative risk of breast cancer.      

Indeed there are several hundred such tests many of which can be conducted using a simple mouth swab.

Chromosomes: Functions and Importance

February 12, 2011 By admin

A chromosome is a coiled sequence of DNA and protein that is found inside cells. It contains necessary information like nucleotide sequences, regulatory elements and genes. Coming from the Greek words chroma (meaning colour) and soma (meaning body), the chromosome is an organised structure that is coloured by certain dyes.

Chromosomes differ according to the type of cells that house them. In cells with nuclei (or eukaryotic cells), chromosomes are usually large and linear. In cells without nuclei (or prokaryotic cells), the chromosomes are normally smaller. But, in spite of these differences, chromosomes are very important parts of cells that carry some really necessary functions that are vital to life.

The proper placement and functioning of chromosomes predispose people to a normal, healthy body. In the same way, when abnormalities are found, disorders and unpleasant health conditions manifest.

The Functions Of Chromosomes
Chromosomes are in charge of all the processes that occur inside cells. Referred to as the “packaging material” that binds DNA and protein together, chromosomes contain genes and other hereditary indicators that play very important roles in the development of an individual.

Chromosomes also control cell division, cell reproduction, cell creation and cell replication. Aside from that, chromosomes make sure, as well, that the correct sequencing of DNA and proteins are embedded in the cell.

The Importance Of Chromosomes
Chromosomes are necessary parts of the human body because they:

- Store necessary genetic information. The things that distinguish one individual from another are managed by chromosomes. DNA is contained inside chromosomes. And if DNA is the personal indicator of the uniqueness of every person, then chromosomes are the tools that make sure that identification is going to be always possible.

- Help with the vital life processes. Cells are the building blocks of life, and chromosomes are instrumental in confirming that our cells will continue to live. What’s even more amazing is that each time that a cell process takes place, it is done perfectly and properly. This is especially evident when a cell divides. When it does, the information that the cell contains get similarly transferred to the new cell.

- Manage protein. Protein is known to be a very important nutrient in the body. It is single-handedly responsible for so many functions that are related to the body’s development. Chromosomes store proteins. Meaning, chromosomes are responsible for housing one of the most important components that dictate proper human functioning.

The Longevity Gene: The Way To Immortality?

February 7, 2011 By admin

Every one of us knows that we are not going to live forever. Mortality is always an issue. That’s why most of us choose to make the most out of our lives so that when the end comes, we can tell ourselves that we have truly lived. But, there is something that is said to be embedded in our DNA that can promise us a longer life, and a longer existence: the longevity gene.

The longevity gene is the gene that, according to some scientists, can be found inside the human body. While it may not be the immortality elixir that some have been obsessed with, it nevertheless contributes to the possibility of living beyond a hundred years, and living well.

The longevity gene allegedly exists in the other organisms, too. Scientists have found, at least, 25 varieties of the gene in animals, and they say that some of those varieties are present in a human body. Some examples of the longevity gene include:

FOX03A – In a study conducted by the Kiel University in Germany, this gene was found in the bodies of people who have lived beyond 100. A separate research done by an American team corroborated what the Germans found. In that study, Americans (who had Japanese origins) did not die until they have lived for a hundred years or so. This gene has puzzled many scientists for a long time, and more of them are starting to think that this may have a hand at predicting how many years a person would live on the Earth.

SIR2 – Associated with improving physical and mental health and thus extending lifespans, the SIR2 gene is also considered as a longevity gene. People who have been discovered to have them in their DNAs have been said to bear better with environmental conditions like drought and heat. There are scientists who say that that translates to having a longer life. Better coping mechanisms have always been favoured on this planet, after all.

However, several debates have surrounded this particular “scientific” claim. Some schools of thought have dismissed the longevity gene theory as outright irrational. But, that does not sway the believers from thinking that living longer is possible, if you have the genetic mapping that would predispose you to it. And, in a world where death news are always evening news, the theory is more than enough to give people hope.

Medical Genetics Research: Importance And Benefits

February 1, 2011 By admin

Medical genetics research covers studies that aim to understand the machinations of hereditary diseases among human beings. Although this field of research science has been linked to human genetics science, there is a big difference between the two.Human genetics research stops at exploring the causes and reasons for hereditary illnesses. Medical genetics research applies whatever is learnt about the diseases to medical science. Diagnosis, treatment and therapy are all touched by medical genetics research.

Genetic screening is one of the most important areas that is managed by medical genetics research. This involves having pregnant people tested for possible genetic abnormalities that may manifest in her baby, and children or adults who think that they may have some form of genetic abnormality. The research finds out what those abnormalities are (if there are any) and from there, see what can be done to correct them.

Medical genetics, as a science, is considered as very important because it deals with not only knowing about the genetic diseases, but also knowing how those diseases can be prevented, stopped, or treated.

Importance Of Medical Genetics Research
Medical genetics research is necessary because it is not news that we all live in a world where illnesses that pass on from generation to generation exist. The research is geared towards finding the explanation for the cropping up of those diseases. And from there, medical genetics research goes on to chart the ways by which the illnesses may be treated.

Also, the counselling (that is sometimes necessary) is incorporated into medical genetics research. This is helpful because there is a countless number of people who desire of dealing with their conditions properly, and moving on from the unpleasant changes that their hereditary conditions have presented. Lifestyle and daily activities are also monitored.

Uses Of Medical Genetics Research
Medical genetics research is normally used to understand more about the following fields:

- Chromosome disorders such as Down syndrome (a disorder that brings about mental retardation), Turner’s syndrome (which is commonly linked to heart problems, short statures and infertility), and Klinefelter’s syndrome (a growth and development disorder)
- Mendelian disorders like Dominant disorders (diseases that are predisposed by the genes of one parent) and Recessive disorders
- Multi factorial disorders that point to neural tube defects (that are connected to high morbidity and long-term disabilities) and others (like cleft lips and cleft palates)
- Prenatal testings
- Cancers and Genetics with breast cancer genes and colonrectal cancers, as examples

DNA Testing: Paternity Issues And More

January 21, 2011 By admin

DNA or deoxyribonucleic acid is the primary holder of all necessary information that dictates how a person’s body is going to function. Vital human functions like cell formation and RNA sequencing are dictated by DNA. The way that a person looks and stands are also managed by a person’s DNA, too.

But, if there is anything that DNA does really well, it is to design the overall individuality of a person. No two persons have the same DNA coding and thus, we all can believe that each one of us are truly unique. This particular DNA characteristic makes it very ideal for conducting medical tests that can sometimes mean the difference between bad and good.

DNA tests (also called DNA profiling, genetic fingerprinting or DNA typing) are tests managed by forensic scientists to differentiate one person from another. They are needed when:

- crimes such as rapes have been committed, and finding the perpetrator would be important
- familial relationships need to be established (such as in the case of paternity exams)

DNA testing starts with collecting a DNA sample from a person. This is usually done by using a buccal swab. However, when doing that is out of the question, a person can submit a sample from his or her saliva, semen, and other body fluids. Stored DNA samples can also be used, like biopsy tissues and sperm from sperm banks.

When paternity is the issue that needs to be settled, upon taking the DNA sample, the DNA testing proceeds on to check if the sample contains inheritance patterns that match the supposed father’s DNA profile. A person’s DNA is half from his or her mother, and half from his or her father. A Paternity Index (or PI) is also used to check the biological compatibility of the two compared DNA samples. Paternity is declared when the matches between the two satisfy the proper amount of PI markers.

DNA testing is also done to not only check genetic illnesses, but prevent their eventual manifestations. Blood samples are taken and analysed to see if alterations in a person’s genes exist. From that, zeroing in on the specific disease would be easy. Corrective measures can then be employed so that the disease would not progress, and get ultimately healed. These DNA tests are actually very necessary, as they can help a person adjust to whatever unpleasant surprises that life may have in store for him or her, act upon them, and ensure the continuation of his or her genes living in his or her future child.
