Penn State College of Medicine researchers, in collaboration with colleagues at the University of Southern California, have taken an important step in understanding the role of cell mother in the development of liver cancer. With a unique approach includes the study of individual cells, the team led by C.
Using a liver -specific PTEN (phosphatase and angiotensin homologue deleted on chromosome 10) mouse model allows Rountree and her colleagues to study the microenvironment of the liver, without affecting the rest of the mouse.
“The blow-out mouse PTEN is a model of chronic injury of the liver that eventually leads to liver cancer. During chronic injury, the cells proliferate and mother of the liver, sometimes healthy liver, the cells of the liver stem are very rare “Rountree said.”We were looking for a principle that is driving stem the proliferation of cells liver during chronic liver injury.
“We started the investigation of liver stem cells in many different models of liver injury with the idea that may be able to help people with liver disease, but we found that some isolated cells were malignant neoplasms,” Rountree said. “It was a surprise to us because there were no tumors in mice when the cells were isolated.”
The liver is the only body organ that is able to regenerate completely. Liver cells, including hepatocytes and cholangiocytes can divide and replenish themselves. With chronic liver injury, including a virus or alcoholism, hepatocytes lose their ability to do more for themselves. In this environment, the proliferation of liver stem cells can make either type of cells. However, patients with chronic injury also develop liver cancer, opening the possibility that stem cells involved in tumor formation.
“There has been a surge of interest in understanding the role of specific stem cells in the development of liver cancer,” said Rountree. “Not a cancer stem cell lurking out there that can be very bad. It has properties of stem cells and malignant, resistant to chemotherapy. These properties make it more difficult to treat these cancers.
“What I ended up doing was changing our understanding of liver stem cells and their role in cancer,” said Rountree. “All the work done previously was looking at patients, animal models or cell lines after the tumor developed. What we did was to identify malignant stem cells before there is evidence that the primary tumor. This gave us a new perspective not only the potential of stem cells for therapy is, but also in terms of what is driving the formation of cancer. Imagine a cancer treatment before it is a primary malignant tumor. ”
The researchers created ten cell lines to study a single cell isolation technique. The cells that produce a unique surface protein called CD133 were separated by placing them in a liquid medium and run through a flow cytometer. Once identified, a robot took single CD133 positive cells and placed in a drop in a well of a culture plate. Doing this hundreds of times, cell lines were established.
These individual cells, when increased to, had characteristics of stem cells with markers of hepatocytes and cholangiocytes. When these lines were injected into a mouse with a deficient immune system, tumors formed.
Rountree said there is interest in using these stem cells with malignant potential. “We can target these cells in patients with hepatitis B or C, either before or after forms of cancer?” Rountree said. “The biggest implication is very powerful. If you look at a patient with a chronic injury and find a way to specifically target cells with malignant potential, may be able to prevent liver cancer in the first place.”

11th September 2001 was the worst day in the memory of New York residents because on this date New York was badly affected from every aspect such as in physical, financial and mental terms.

A patient who has been diagnosed with cancer or any kind of chronic illness is usually required by the doctor to undergo a surgery. This is to prevent the possibility of causing any complications to the other vital organs of the body. Although it would be a toughed decision on the part of the patient but, for the sake of early recovery he should abide with the doctor’s advice. Unless, the patients possible recovery or survival is so small then it would be the patient options whether to undergo the surgery or not.
However, it is also a case to case basis. Cancer varies from one person to another. The case of one patient is entirely different from the other patient. Reason that, doctor’s advice or recommendation is very vital. For example like in the case of having cancer in the bladder. The patient’s urinary bladder is removed as a result thereof. With this, it is recommended that the patient should undergo an Indiana pouch surgery. This kind of surgery is proven to be effective, convenient and reduces the possibility of having kidney problem.
But before that, the patient is required to know the needed things to be done before undergoing an Indiana pouch surgery. As part of the post operation requirement, the patient is not allowed to eat solid food and even drink large amount of fluids at midnight before the surgery. This is to avoid excretion of stool during the surgery.
Indiana pouch is surgically made urinary diversion designed to store, eradicate or eliminate the urine of the patient after undergoing a surgery. This kind of pouch is used to hold the urine after the ureter is removed from the patient’s bladder. In this stage, the patient is required to be confined in the hospital for seven to ten days for abdominal surgery. There are three drainage tubes place in the abdomen of the patient after the surgery. First tube is placed through the stoma or the small opening in the abdominal wall. The second tube is brought out through another temporary opening in the abdominal wall. The third tube is called the SP tube where the abdominal fluid is drained. In addition, this will entail a lot of process from the time the first tube is taken out of the patient’s body and until such time that the patient is now capable of putting in place the catheter into the pouch on specified schedule as prescribed by the doctor. It is a very daunting task on the part of the patient to self-catheterize the pouch, emptying the pouch at night and cleaning the pouch to remove the mucus or bacteria. With this, he is in need of someone to assist him all the time particularly from any member of his family. After the patient is healed, he may perform his routine work as he pleases. Except those activity that is clearly prohibited like lifting of heavy things or doing an extraneous work. By following the doctor’s advice the patient will never be put into trouble.
Thus, Indiana pouch is more advantageous compared to other surgical process because of the convenience it brings to every patient. Provided that the patient either young or adult alike understand things needed to be done. Likewise, the patient should know how to catheterize the pouch and to follow the instructions on schedule.
Did you know that Radon (a colorless & odorless gas that sometimes accumulates in basements or other confined areas in the house) can cause lung cancer? In fact, United States Environmental Protection Agency states that after cigarettes, Radon gas is the most recurring cause of lung cancer in United States. This means, you can be exposed to the risk of developing lung cancer while living in a particular building, without even knowing it. The reason for all this information is not to scare people, but to highlight the importance of knowing (and doing something) about the probable environmental hazards in your residential or commercial properties. It also means that you must take environmental hazards into consideration when buying a property.
Environmental issues are becoming a much bigger concern with the passage of time, as new discoveries and researches continue to reveal, how a seemingly harmless element can cause serious damages. Even though, most of these hazards can be taken care of once they are identified, but it can be a costly procedure. Therefore, this information must be a part of your buying decision, especially when you are negotiating on price. In some states, laws are being introduced, asking property sellers to disclose such information at the time of sale, but even if such laws are not practiced, it is a buyer’s right to be sure of the nonexistence of such environmental vulnerabilities.
Asbestos:
Asbestos is a type of fiber which was used in a number of products in the past. People, who are exposed to high level of asbestos, can develop mesothelioma, lung cancer or asbestosis (due to the inhaling of asbestos particles). Although, Asbestos is not used in product manufacturing anymore, it is still found in older products and homes. Therefore, you should consider hiring some Asbestos professional, if you are going to buy an old home.
Radon Gas:
As stated above, Radon gas is an odorless gas that can cause serious breathing problems. There are test kits in the market to examine the air quality and radon level in the living areas. There are various ways to remove or reduce radon accumulation. For example, you can make use of ventilating fans. Note that radon is mostly a problem in confined areas like basements and high radon levels are not likely in good airy rooms, with windows and proper ventilation.
Lead:
Lead particles can be ingested that results in damage to the bones, blood or nervous system (especially in the children). It can dissolve into the drinking water, making it hazardous to consume. Use of lead in any form is prohibited especially in the homes or products that deal with children.
A woman has noted she will wait until after she returns from a climb up African mountain Kilimanjaro before trying out some new roller skates.Writing on WalesOnline, health editor Madeleine Brindley revealed she bought the items this summer.She is a member of the Brains SA Captains Climb team, which will head up the world famous landmark in September.
Along with 15 former Wales captains and current coach Warren Gatland, she is attempting to raise £1 million for the Velindre Cancer Centre’s Stepping Stones appeal.The initiative was launched in a bid to raise awareness of the appeal and to generate money to further its research programmes.
According to those behind it, lung cancer is the most common cause of cancer death in England and Wales and it is not only smokers who are affected.Commenting on her decision to get skates, Ms Brindley said: “I bought a pair of roller skates, partly on a whim and partly to satisfy a childish sense of injustice.”I never owned a ‘proper’ pair of skates – I had to make do with a pair of metal strap-on skates that fitted around my trainers.”
The pair that she purchased would be good for roller skating in discos she claimed.However, at the moment they are simply gathering dust, she admitted, as she is too concerned about injuring herself prior to her charity endeavour.She added: “It’s not that I’ve gone off skating, I just feel I can’t risk skating, injuring myself and jeopardising Kilimanjaro.”
Ms Brindley went on to say she is in “full-blown safety mode” at present and is being extra cautious in everything she does, meaning roller skating is temporarily off the cards.For example, when she takes a morning run, she concentrates on not twisting an ankle and she double-checks where she puts her feet while on her weekend hikes.
