Hair Cloning Research for Hair Transplant Procedures

The future of hair transplant procedures is in the laboratories at this very time. Scientists are working together to find a way to make the surgery work for more people. They also want to see it work better for the types of people who have hair transplants today. One area of research is hair cloning.

Hair cloning promises to be a revolutionary procedure that would give people with little hair a chance to have hair transplant surgeries. It would do this by multiplying the hair a patient already has rather than using up the good hair that still exists on the patient’s head.

Hair cloning is done by taking stem cells, or dermal papilla cell, and cloning them in a laboratory setting. They are then multiplied and combined. The end result is an increase in the number of hairs available for hair transplant.

Not only is hair cloning possible, it has been proven in many scientific studies. Recently one group of researchers did a culture whereby they multiplied the number of dermal papilla cells. With this being possible, hair cloning is a single step away.

Hair transplant procedures that use cloned hair are farther off, though. The research cannot be done as to whether these hairs can safely and effectively be transplanted onto a person’s scalp yet. First, they cloning process will have to be completely perfected. Only then can the hair transplant trials begin.

More research needs to be done to find out which hair cells can be used for hair cloning and then hair transplant procedures. Some of the available cells go through several stages before ending in cell death in a very short time. These cells would not be adequate for use with hair transplant surgery. There seem to be other cells which last longer and would work for this application.

A scientist named Dr. Gho has done some work and acquired a Dutch patent on his work with hair multiplication. It is unclear whether this is much like hair cloning or not. That is because Dr. Gho neglects to submit his findings to be published in medical journals. Without review by other doctors, Gho’s theories cannot be tried and evaluated.

Certain types of auto-immune diseases, such as alopecia areata can now be treated by means of hair transplant techniques by using the donor strip method. Yet, in the future, hair cloning will make hair transplant easier for these people who often have very little hair to use for grafts.

Some people believe that hair transplant grafts using cloned hair would be about the same cost as the usual hair transplants that are available today. Other experts believe that the price will be much higher – perhaps three or four times per graft higher – because of the specialized methods required to do the work.

Hair cloning is probably not as far away as one might think. It might be ready for use with hair transplant procedures as soon as five years from now, or even sooner. If you are considering getting a hair transplant but you want to wait awhile, hair cloning is something to think about.

How Can Genes Contribute to and Cure Congestive Heart Failure?

How Can Genes Contribute to and Cure Congestive Heart Failure?

It is common knowledge that heart failure follows another severe form of heart damage; however, until now scientists and doctors have had no way to identify those at risk. New research into genes and gene therapy have made them a potential weapon in the fight against heart failure.
Scientists have made several discoveries regarding the role of genes in the detection and treatment of heart failure. Several years ago it was discovered that a small percentage of patients who had suffered heart failure possessed a defect in the gene that allows the body to detect stress signals; in essence, the heart does not know that it is working to hard and is unable to adjust. This percentage may seem insignificant; however, the gene mutation was not present in any of the healthy patients examined. Researchers stress that this is a susceptibility factor, not a cause of congestive heart failure; however, it may be the breaking point when determining if a heart suffering from other disease will fail. Detection of this mutation may allow doctors to identify and treat patients at risk prior to their heart failing rather than after.

This defect is found in the ATP-sensitive potassium channels and is caused by a genetic mutation. The potassium channel regulates potassium and calcium levels in the body. While the heart must have calcium to function, an excess of calcium leads to damage. This is the reason calcium blockers are often given to patients with congestive heart failure. Fortunately, medications to open the potassium channel already exist.

In addition, a defect of the delta-sarcoglycan gene has been seen in hamsters with muscular dystrophy and cardiomyopathy. This gene is the cytoskeleton of muscle fibers, and successful transplant of a normal human delta-sarcoglycan gene has been shown to cause a tremendous improvement in these animals. This is noteworthy because current transplant attempts require open heart surgery. This type of gene transplant is carried on a virus, eliminating the need for surgery.

Scientists had been a bit concerned with using this method of gene therapy due to the need for a systemic effect. There was also some concern that the body’s natural immune system would eliminate the virus of its own accord prior to successful delivery of the gene; however, they believe they have found the best form of virus to successfully slip past the body’s defenses. When transplanting the delta-sarcoglycan gene researchers used a type eight adeno-associated virus, piggybacking the corrective gene onto it as it was inserted into the body. This allowed the gene to be carried to all areas of the body in animals with muscular dystrophy without being destroyed by the body’s own natural immunity.

Gene therapy is still highly experimental, and researchers are unsure yet of the role it will play in the conquest of heart failure; however, this represents a technology that was unavailable thirty years ago. Continuing advancements in technology and medicine’s knowledge of the body’s building blocks may one day unlock the mysteries to the cure of this deadly disease.

Manifestations of Arthritis

Manifestations of Arthritis
Amanda Baker

One of the most common conditions in the United States today is
a debilitating inflammatory disease that affects our joints. It
is estimated that there are over 100 different forms of this
disease and over 40 million people suffer from one form or
another.

Though typically thought to be an affliction of the aging,
arthritis can affect anyone at any time, and with all of the
different forms, each with their own symptoms, it could be hard
to determine just what type of arthritis an individual is
suffering from.

The signs and symptoms of arthritis are varied, though some of
the first symptoms are familiar and easy to recognize. Symptoms
such as general pain or swelling around the joints, an increased
stiffness in the joints in the morning, a cracking sound in the
knees when standing, and joints with a red appearance that feel
warm to the touch are all signs of arthritis.

However, before you rush to purchase an over-the-counter
arthritis treatment, you should talk to your doctor. Your doctor
is the only one who will be able to tell you what form of
arthritis you may have and how to treat it.

Rheumatoid arthritis is one of the most common forms of
arthritis that plagues sufferers. It affects the joints and is a
systemic disease that can affect other organs. Rheumatoid
arthritis symptoms tend to disappear after sometime, but the
problem is still there. The true cause of rheumatoid arthritis
is presently unknown, though many suggest that things such as
infections, fungi, or bacteria are the culprits. However, there
are also those that believe that rheumatoid arthritis is
hereditary. Painful and swollen joints are a common warning sign
of rheumatoid arthritis, followed by muscle pain, extreme
fatigue, redness and warmth at the joints, even a low grade
fever and appetite loss.

Next to rheumatoid arthritis, osteoarthritis is a common
affliction, caused by breaking down of joint cartilage.
Osteoarthritis commonly begins in one joint and typically only
affects the one joint. It does not move to internal organs.
Osteoarthritis commonly affects the knees, hips, hands, and
spine. By the time the pain starts setting in for an
osteoarthritis sufferer, the damage to the affected joint
cartilage could be considerable.

Relieving pain from a form of arthritis can be as simple as
over-the-counter or prescription medication. However, in the
most severe cases, surgery may be necessary. Being overweight
can also play a role in arthritis. Some physicians believe that
a change in diet can ease the pain of arthritis, though there is
a lot of debate on the topic. Regardless, you should speak to
your doctor who can tell you just what form of arthritis you may
have, and what treatment options may work best for you.

Appendicitis in Kids

Many children have their appendix removed even before turning the age of fourteen. And the risk starts to peak as they age. Majority of children who get an abdominal surgery is because of appendicitis. Appendicitis is actually appendix inflammation and as a result, a fingerlike tube grows on the lower right part of large intestine. Appendix is located at the closed end of the larger intestine, known as the cecum, and measures up to many inches. Although, doctors say that the appendix isnt of much help to the body, but appendixs inner wall releases antibodies, which are produced by the lymphatic tissues.

Appendicitis can be detected by the onset of pain in the middle portion of the abdomen, the portion above the belly button. After a few hours the area will swell and there will be intense pain when touching the abdomens right side. The patient will begin to vomit and will have nausea. There will low fever and there will be problems will gas and stool passage. Some people, after the onset of these symptoms, will take laxatives or enemas mistaking appendicitis for constipation. But this is extremely dangerous, as these medicines will in turn increase the risk of the appendix bursting. So it is recommended to consult the doctor before going for any kind of medication, even any pain relievers. Besides increasing the risk, they even mask the symptoms and makes diagnosis even more hard. If the childs symptoms are very much similar to that of the appendicitis symptoms, he should be immediately taken to the doctor for further diagnosis. The doctor will first study the childs digestive illnesses history. He should also be divulged information about the symptoms, timing, bowel movements and its frequency. The stool should also be checked for mucus or blood. Children, who can communicate, can be asked to point out the location of pain in the abdomen. Toddlers who havent started talking or who hesitate to do talk will raise their knees close to the chest, hips will be flexed and the abdomen becomes tender.

Although, the actual cause of this abnormal growth of the appendix is not known, but it can result because of some kind of obstruction or infection in the intestines. The obstruction can be created due to thick mucus build-up inside the appendix. Some part of the stool can also enter inside. There will be mucus formation and the stool will harden within resulting in the swelling up of the appendix. If it is an infection, it should be treated immediately, as it can burst and there is a danger of the infection spreading to other parts of the body via bloodstream. That is the reason why even blood test is done, so as to determine whether the infection has spread or not. The urine test is done to check for problems in the urinary tract. The problem is then confirmed with the help of computed tomography or an ultrasound. Sometimes children with pneumonia have the similar symptoms, so to make matters clear even X-ray of the chest is done. Medical attention must be sought within forty eight hours of the start of the abdominal pain. Sometimes, abdomen develops mild inflammation, many weeks before the diagnosis is done.

After the diagnosis is done and appendicitis is determined, appendectomy is performed on the patient. The doctor will immediately order the intake of antibiotics before the surgery is performed. In case of confined appendicitis, it can be treated solely by antibiotics and no surgery is required. This is because the inflammation is very mild and the body itself fights with the infection. But, still as a precautionary measure, such kinds of patients must be kept in observation until their condition becomes stabilized. If the appendix ruptured then appendicle perforation is done. In this procedure, a drain is inserted inside the skin, through the abscess with the help of CT scan or ultrasound which gives the exact location. Some people develop complications later such as wound infection and accumulation of puss inside the appendix.
