Mesothelioma Victims

Reactions:  
Mesothelioma is not a disease that can be detected easily as it rarely gives out symptoms at its early stage in the body. Even with the symptoms, diagnosing the disease is difficult as these symptoms are very common with other diseases too.

Within this backdrop, patients' medical histories can help diagnose the disease. Therefore, physicians inquire about a patient's medical history if they suspect mesothelioma might be the case. Then the X-ray is performed and if necessary CT scan or MRI is also performed.

With these scans, the amount of fluid if it is present can be seen and this fluid is then aspirated with the help of a syringe. While a pleural tap is used to extract pleural fluid, the fluid in pericardial cavities is taken out by pericardiocentesis. Paracentesis is performed to take out fluid in abdomen.

If these fluids give out evidences of having mesothelioma, physicians do further tests on patients to prove the conditions clearly. At this stage, mostly a biopsy is done and tissues are sent to the pathologist for microscopic tests. Depending on the locations of the cancer, the methods used for biopsies can be different from each other. As an example, for cancer in the chest, thoracoscopy is performed to get tissues, in which, the physician make small incision on the chest wall and insert a thoracoscope between the ribs. In this way, the doctor can examine the inside of the chest cavities and extract tissue samples for microscopic testing.

On the other hand, to get tissue samples from a mesothelioma patient in the abdominal cavities, a laparoscopy is done. During this procedure a very small cut is made on the abdominal areas large enough to insert an instrument into the abdomen. Sometimes the procedure is not sufficient to take out enough tissues for the microscopic test and if this is the case, another major surgery has to be performed.

The risk if you smoke

Reactions:  
You will lose a lot money if you smoke, illustration if you smoke one pack of cigarettes a day at $2.00 per pack, you spend $730 per year. If your habit has continued for a period of 20 years you will have spent an incredible $14,600! If you smoke two packs for that same period of time, you will spend $29,200!

You will be twelve times more likely to die from lung cancer. ten times more likely to die from some form of lung disease. ten times more likely to die from cancer of the larynx. six times more likely to die of heart disease. twice as likely to die of a stroke.

Not only for your health, you also help your friends and human around you to die, yes you help them to die faster.
Pentachlorophenol is a phenolic compound that was chlorinated. Pentachlorophenol very toxic for our breath, cause dermatitis on skin and more toxic than inorganic solvent.

Pentachlorophenol waste almost dissolvable in water so degradation process is very hard. Some ways have been done to solve biological waste problem, but not efficient enough. For example, active carbon just involve pollutant absorption without decomposition process. Chemical oxidation process can’t decomposition all of organic compound be carbon dioxide and water, and have been used in high concentration waste.

Many century ago, scientist success to describe phenomenon photocatalytic in surface of metal-oxide semiconductor. Firstly, have been issued by Renz in 1921 until 1960, and not responding by scientist. Photocatalytic semiconductor popularity increase since publication Akira Fujishima in Nature magazine was issued in 1972. He was reported decomposition water be oxygen and hydrogen used single crystal TiO2 with input UV light in low energy.

First research, TiO2 have been used as photocatalytic suspension system. Nowadays, the uses TiO2 as photocatalytic is used in thin plate shape, which is immobilization TiO2 to many kinds of supported material like fiber, glass, silica, and titanium plat.
