bubble has know a hollow organ in the lower abdomen to the pelvic area that stores urine from the kidney. Bladder cancer is the most common forms of cancer seen in the elderly. the men will be infected by this tumor more than women. Studies indicate that the ratio of men to infect 1:30 is sufficient, while for women the ratio 1: 90

bladder cancer can be benign or limited to the inner wall of the bladder, or it can be with malignant spread of the muscular portion of the bladder. Bladder cancer is said, has spread through the lymphatic and blood cells to other parts of the body, infected, and more. Transitional cell carcinoma, squamous cell carcinoma and adenocarcinoma: Bladder cancer can be divided into three different categories. Transitional cell carcinoma is the most common form of bladder cancer and almost 90% of people with bladder cancer have this type of cancer

causes. there are several factors that lead to this type of cancer. first, it is because of his age more than one person. secondly, people with excessive consumption of fried meat and animal fats in the diet, a greater risk for this form of less cancer. Smoking increases the risk of bladder cancer. then there are too many chemicals, cancer of the bladder.

people working in industries that are with aromatic amines sick of this common problem. in addition to persons in the leather industry, paint, textiles, rubber, hair dye and painting in danger. there are others who consume below the weight loss program, a Chinese herb called Aristolochia fangchi “which is allegedly the cause of bladder cancer.

There are other causes, as when a person has a urinary tract infection for a long period of suffering, then it is too susceptible to this tumor. Hereditary factors can not be ignored

symptoms. bladder cancer has no unusual symptoms . Infact, the symptoms are very similar to a urinary tract infection. the most important symptom is blood in the urine. then there is to see other things, urinating like a burning sensation when urinating, frequent urination, urgency, every half hour, but the amount of the urine to come is much lower.

Although these symptoms are not very typical for bladder cancer, nor should we go to a urologist with any type of cystitis. but in the Bladder cancer symptoms are not apparent until a later stage of infection. This is very risky because it is known that all tumors are difficult to heal at an advanced stage.

After the presence of the tumor was established, it is important to go for treatments such as chemotherapy, radiotherapy, surgery, immunotherapy or biological therapy as soon as possible. However, the duration of treatment depends on tumor type, age and health of the person . bladder cancer, it is known that it later reproduce. people who should suffer from frequent urinary tract infections or a history of bladder cancer are regular screening for early detection of cancer.

Commonly known as Cooley’s anemia, beta-thalassemia affects nearly 1,000 individuals in the United States; worldwide, approximately 300,000 children are born each year with thalassemias. The conditions cause excessive iron absorption in the body’s organs, with symptoms including fatigue, liver disease, heart failure, growth impairment, diabetes and osteoporosis. Standard treatment involves regular blood transfusions, which are often ineffective, or bone marrow transplants, which can help to replace and repair the broken blood production of the body.

Hepcidin, a hormone found naturally in the bloodstream and acting at the level of the digestive tract, has been known to be at low-levels in patients with beta-thalessemia. Now, the researchers have evidence that boosting levels of hepcidin may actually have a direct effect in relieving anemic patients of their body’s iron overload, potentially relieving the ravages of these conditions.

“The major consequence of iron-overload is that the lifespan of a red blood cell is half that of a normal red blood cell. These blood cells are not properly formed, are not as healthy as normal blood cells, and, therefore, cannot properly function,” explains Dr. Stefano Rivella, associate professor of genetic medicine in the Department of Pediatrics at Weill Cornell Medical College.

In the Journal of Clinical Investigation study published online on Nov. 22, Dr. Rivella and his colleagues report that breeding mice that overproduce hepcidin with other mice suffering from beta-thalassemia led to offspring that were almost as healthy as normal mice. However, when they crossed the hepcidin-expressing mice with normal mice, hepcidin levels were too high, leading to too much iron removal and an inability to produce healthy red blood cells.

“We see from this evidence that there is a balance in the body — not too much iron and not too little iron — that must be maintained to keep iron levels normal in order to produce normal blood cells,” says Dr. Rivella.

He explains that under normal conditions, hepcidin recognizes when there are not enough red blood cells. In turn, the body will then produce the correct amount of hepcidin, which regulates the amount of iron needed.

“In patients with beta-thalassemia, this mechanism isn’t working — it’s as if the raw materials — the iron — are being sent into a factory, but since no products — blood cells — are being made, more and more iron is being sent in and stored in the body’s organs,” explains Dr. Rivella.

Hepcidin’s Influence on Hemochromatosis and Iron Overload

A second study published in a recent issue of the journal Blood, and authored by Dr. Rivella and his lab, illustrates a potential new dietary treatment for patients with hemochromatosis. this anemic disease is caused by a mutation to the HFE gene, leading to lowered production of hepcidin. The disorder affects nearly 1.5 million individuals in the United States.

Hemochromatosis interferes with the body’s ability to break down iron, resulting in too much iron being absorbed from the gastrointestinal tract. Like in beta-thalassemia, patients often have iron buildup within the liver, which could lead to liver failure and sometimes liver cancer.

For treatment, patients often have blood taken out of their body, called phlebotomy. Doing so is believed to force the body to remove iron from the liver, reducing iron overload within the organ. Patients return regularly to the doctor’s office to have blood removed, in order to lower iron levels in the body, but the procedure is not so effective and could be improved, as Dr. Rivella and his colleagues describe in their study.

“We’ve learned that in hemochromatosis the body will always look to the diet in the gut for iron and not take it from the liver,” explains Dr. Rivella. “Therefore, a low-iron diet immediately following phlebotomy may force the body to look primarily to the liver for its iron supply.”

To test their hypothesis, Dr. Rivella tested three different groups of mice: normal mice on a normal diet (group 1), normal mice given a high-iron diet (group 2), and mice with hemochromatosis on a normal diet (group 3). Group 2 was given a high-iron diet in order to raise iron levels in the liver, similar to mice in group 3.

Each group had blood removed through phlebotomy and then had their hepcidin levels tested. a low level of hepcidin would indicate that the hepcidin is being utilized to absorb iron from the gut.

Results indicated that group 1 behaved as expected: Blood was removed and found to have low levels of hepcidin, meaning that the body was absorbing iron from the digestive tract.

Group 2 had higher levels of hepcidin because the body was able to recognize that there was a reservoir of iron within the liver, illustrating that hepcidin was needed to prevent the iron from being absorbed from the gut.

However, the levels of hepcidin in group 3 was low because the body was unable to recognize a high level of iron in the liver because a genetic mutation lowered the production of hepcidin, resulting in iron being taken from the gut instead of the liver.

“The implications of these findings are that if you take out the blood from patients with hemochromatosis, the body will still look to take readily available iron from the diet, instead of from the overloaded iron packed in the liver,” explains Dr. Rivella.

Recently, Dr. Rivella and collaborators at UCLA were awarded a $4 million grant from the National Institutes of Health to test a drug that mimics hepcidin in people with beta-thalassemia and hemochromatosis. they hope to show that boosting hepcidin in the body helps to better treat their iron overload and anemia.

According to researchers, the genetic markers will help pave the way to predict who will succumb to debilitating lung infection and use the information for vaccines, better diagnose and early treatment of the disease.

“Although people have been studying TB for more than a century, there is still a desperate need for better prognostic and diagnostic tests and more information about the body’s response to MTB infection, which may also help in the design of vaccines and treatments,” said Anne O’Garra, of the Medical Research Council, who led the study.

Genetic profiles compliedIn the new study, researchers drew blood from TB patients and from healthy people in UK, US and South Africa.

They then analyzed the gene activity in the blood cells and complied profiles of the genetic activity in the blood.

It was noted that people with active infections had 393 genes with activity different from that seen in healthy people.

The same gene expression was found in about 10 percent of patients with latent infections, indicating that they were vulnerable and may go on to develop the disease even if their infection is currently dormant.

The researchers will follow up the patients to see if they go on to develop the full blown symptoms of TB in future.

If the results are promising, the blood profiles could be the first means of predicting who is likely to get sick from TB.

Lead researcher Dr Anne O’Garra of the MRC’s National Institute for Medical Research in London, said, “If you could predict which so-called carriers of TB will progress to the full-blown disease, this would have major ramifications for stopping the global epidemic.

“We just have to prove it now, but it’s very promising.”

The study was published in the journal ‘Nature.’

A little about tuberculosisTuberculosis (TB) is a bacterial infection caused by a germ called Mycobacterium tuberculosis. It is an infectious disease which usually affects the lungs, but can also damage other parts of the body.

TB is transmitted through the air when an infected person coughs, sneezes or talks. Symptoms of TB include coughing up blood or mucus, chest pains, weakness, weight loss, fever and night sweats.

You are more likely to get TB if you have a weak immune system. in healthy people the infection generally causes no symptoms.

If exposed to the infection, there is an urgent need to go to the doctor for tests. TB if not treated properly can be deadly. The disease can be cured with a course of antibiotics.
