Mesothelioma

Mesothelioma, more precisely malignant mesothelioma, is a rare form of cancer that develops from the protective lining that covers many of the body's internal organs, the mesothelium. It is usually caused by exposure to asbestos.^[1]

Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the heart,^[2] the pericardium (a sac that surrounds the heart) or tunica vaginalis.

Most people who develop mesothelioma have worked on jobs where they inhaled asbestos and glass particles, or they have been exposed to asbestos dust and fiber in other ways. It has also been suggested that washing the clothes of a family member who worked with asbestos or glass can put a person at risk for developing mesothelioma.^[3] Unlike lung cancer, there is no association between mesothelioma and smoking, but smoking greatly increases the risk of other asbestos-induced cancers.^[4] Those who have been exposed to asbestos often utilize attorneys to collect damages for asbestos-related disease, including mesothelioma. Compensation via asbestos funds or lawsuits is an important issue in mesothelioma (see asbestos and the law).

Asbestosis

Asbestosis is a chronic inflammatory and fibrotic medical condition affecting the parenchymal tissue of the lungs caused by the inhalation and retention of asbestos fibers. It usually occurs after high intensity and/or long-term exposure to asbestos (particularly in those individuals working on the production or end-use of products containing asbestos) and is therefore regarded as an occupational lung disease. People with extensive occupational exposure to the mining, manufacturing, handling or removal of asbestos are at risk of developing asbestosis.^[1] Sufferers may experience severe dyspnea (shortness of breath) and are at an increased risk for certain malignancies, including lung cancer but especially mesothelioma.^[2] Asbestosis specifically refers to interstitial (parenchymal) fibrosis from asbestos, and not pleural fibrosis or plaquing.

Ada ALIEN di Batu Meteor ?

Fosil bakteri di meteorit

Richard B Hoover adalah salah seorang Ilmuwan NASA yang telah menunjukan bukti adanya makhluk hidup dalam meteorit. Ia dan timnya mengklaim bahwa di dalam bongkahan batu meteor tersebut ada bukti makhluk hidup berupa fosil bakteri langka.

Minggu 6 Maret 2011, Hoover menuliskan bukti itu dalam jurnal "Journal of Cosmology" edisi maret 2011 seperti yang dilansir oleh CBSNews.com. Ia berpendapat bahwa hasil uji pada koleksi sembilan meteorit yang dinamakan CI1 Meteorit Carbonaceous, itu menunjukkan bahwa ada bakteri yang berasal dari daerah asal meteor.
