Brain Cancer
A brain tumor (sometimes referred to as brain cancer) occurs when a group of cells within the brain turn cancerous and grow out of control, creating a mass. There are two main types of tumors: malignant (cancerous) tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved. Where symptoms exist, they may include headaches, seizures, problems with vision, vomiting and mental changes. Other symptoms may include difficulty walking, speaking, with sensations, or unconsciousness. The cause of most brain tumors is unknown, though up to 4% of brain cancers may be caused by CT scan radiation. Uncommon risk factors include exposure to vinyl chloride, Epste ...

Mobile Phone
A mobile phone or cell phone is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones ( landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. These include text messaging, multimedia messaging, email, and internet access (via LTE, 5G NR or Wi-Fi), as well as short-range wireless technologies like Bluetooth, infrared, and ultra-wideband (UWB). Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Phone Radiation And Health
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation ( non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion). Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation associated with mobile phone antennas or cell phone towers is affecting human health. Mobile phone networks use various bands of RF radiation, some of which overlap with the microwave range. Other digital wireless systems, such as data communication networks, produce similar radiation. In response to public concern, the World Health Organization (WHO) established the ''International EMF (Electric and Magnetic Fields) Project'' in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 t ...

Devra Lee Davis (born June 7, 1946) is an American epidemiologist, toxicologist, and author of three books about environmental hazards. She was founding director of the Center for Environmental Oncology at the University of Pittsburgh Cancer Institute, and is a former professor of epidemiology at University of Pittsburgh Graduate School of Public Health. She has served on several governmental and non-governmental organizations, conducting research and advocacy into effects of pesticides, asbestos, and wireless radiation on human health, especially cancers. Davis is the founder and president of the Environmental Health Trust, a non-profit organization which argues that mobile devices, WiFi, 5G, and other radio-frequency systems pose a health risk to humans and the environment. She has been called a "crusader in the fight over cell phone safety" and believes that radio frequencies could cause cancer. Such claims have been challenged by critics as being bereft of credible argume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Heart Foundation Of Australia
The National Heart Foundation of Australia (known as the Heart Foundation) is a charity established in 1959. Its activities have been funding cardiovascular research, supporting health professionals in their practice, developing health promotion activities, informing and educating the public and assisting people with cardiovascular disease. It describes its mission as "to reduce heart disease and improve the heart health and quality of life of all Australians through our work in Risk Reduction, Support, Care and Research." History The organisation emerged after tuberculosis had been effectively removed as a health concern and after the successful establishment of the Heart and Stroke Foundation of Canada. A group of concerned Sydney professionals meet with the trustees of R.T Hall Trust and members of the New South Wales government health services in July 1958 and decided to form the National Heart Foundation of Australia. Programs Supporting and informing The foundation provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statin
Statins (or HMG-CoA reductase inhibitors) are a class of medications that lower cholesterol. They are prescribed typically to people who are at high risk of cardiovascular disease. Low-density lipoprotein (LDL) carriers of cholesterol play a key role in the development of atherosclerosis and coronary heart disease via the mechanisms described by the lipid hypothesis. As lipid-lowering medications, statins are effective in lowering LDL cholesterol; they are widely used for primary prevention in people at high risk of cardiovascular disease, as well as in secondary prevention for those who have developed cardiovascular disease. Side effects of statins include muscle pain, increased risk of diabetes, and abnormal blood levels of certain liver enzymes. Additionally, they have rare but severe adverse effects, particularly muscle damage, and very rarely rhabdomyolysis. They act by inhibiting the enzyme HMG-CoA reductase, which plays a central role in the production of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Disease
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina pectoris, angina, myocardial infarction, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, Thrombosis, thromboembolic disease, and venous thrombosis. The underlying mechanisms vary depending on the disease. It is estimated that dietary risk factors are associated with 53% of CVD deaths. Coronary artery disease, stroke, and peripheral artery disease involve atherosclerosis. This may be caused by hypertension, high blood pressure, tobacco smoking, smoking, diabetes mellitus, lack of physical exercise, exercise, obesity, hypercholesterolaemia, high blood cholesterol, poor diet, excessive alcoholic beverage, alcohol consumption, and poor sleep, amo ...

Cholesterol
Cholesterol is the principal sterol of all higher animals, distributed in body Tissue (biology), tissues, especially the brain and spinal cord, and in Animal fat, animal fats and oils. Cholesterol is biosynthesis, biosynthesized by all animal Cell (biology)#Eukaryotic cells, cells and is an essential structural and cholesterol signaling, signaling component of animal cell membranes. In vertebrates, hepatocyte, hepatic cells typically produce the greatest amounts. In the brain, astrocytes produce cholesterol and transport it to neurons. It is absent among prokaryotes (bacteria and archaea), although there are some exceptions, such as ''Mycoplasma'', which require cholesterol for growth. Cholesterol also serves as a Precursor (chemistry), precursor for the biosynthesis of steroid hormones, bile acid and vitamin D. Elevated levels of cholesterol in the blood, especially when bound to low-density lipoprotein (LDL, often referred to as "bad cholesterol"), may increase the risk of ...

Saturated Fat
A saturated fat is a type of fat in which the fatty acid chains have all single bonds between the carbon atoms. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone, and fatty acids that each contain a long linear or branched chain of carbon (C) atoms. Along the chain, some carbon atoms are linked by single bonds (-C-C-) and others are linked by double bonds (-C=C-). A double bond along the carbon chain can react with a pair of hydrogen atoms to change into a single -C-C- bond, with each H atom now bonded to one of the two C atoms. Glyceride fats without any carbon chain double bonds are called saturated because they are "saturated with" hydrogen atoms, having no double bonds available to react with more hydrogen. Saturated fats are generally solid. All fats, both saturated and unsaturated, contain 9kcal per gram making them more energy dense than both proteins and carbohydrates. Most animal fats are saturated. The fats of plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
