SELF MEASUREMENT OF BLOOD PRESSURE (SMBP):
SELF MEASUREMENT OF BLOOD PRESSURE (SMBP): ________ The figure above shows correct way to measure blood pressure at home. _______ Prologue: When the heart beats it generates a pressure in the arteries to pump blood around the body. In some people, the pressure generated is too high and this is called hypertension. Way back in 1981, Dr. R. C. Hansoti was head of cardiology department in Nair hospital, Mumbai and he was taking a clinic on hypertension for a group of medical students and I was one of the medical student attending his clinic. He asked a question to everybody: What are the symptoms of hypertension? Some said headache, some said giddiness and some said palpitation. When my turn came, I said hypertension has no symptoms. Dr. Hansoti was satisfied with my answer. He said that there is only one wise doctor among the crowd. I felt elated. Even today, I […]
ALCOHOL (beverage based on ethanol)
______ ALCOHOL (beverage based on ethanol): ______ President Obama loves Irish beer and celebrates the St.Patrick’s Day only with it! ________ Prologue: Abraham Lincoln said: “It has long been recognized that the problems with alcohol relate not to the use of a bad thing, but to the abuse of a good thing.” We find alcohol throughout our daily lives. Alcoholic beverages have been consumed by humans since prehistoric times for a variety of hygienic, dietary, medicinal, religious, and recreational reasons. We associate the consumption of alcohol with the most pleasurable aspects of our culture. Parties and sports, picnics and vacations, summer and winter are all influenced by the attraction of alcoholic beverages. World Cup 2014: festival of football or alcohol?

SCIENCE OF LANGUAGE
_ SCIENCE OF LANGUAGE: _ The figure above shows English to Gujarati mappings for consonants: _________ Prologue: Human life in its present form would be impossible and inconceivable without the use of language. To the question: “Who is speaking?” Mallarme, the French poet, answered, “Language is speaking.” The traditional conception of language is that it is, in Aristotle’s phrase, sound with meaning. Everybody uses language, but nobody knows quite how to define it. Language is arguably the defining characteristic of the human species, yet the biological basis of our ability to speak, listen and comprehend remains largely mysterious; about its evolution, we know even less. The origin of language is a widely-discussed topic. Whole doctorates have been based on it, thousands of books have been written on it, and scholars continue to argue about how and why it first emerged. Many animals can communicate effectively with one another but humans […]
MEDIA
_______ MEDIA: ______ ________ Prologue: When traditional American & Indian media started blocking my comments on internet, they thought nobody would know as they control power to disseminate information via newspapers and televisions. They underestimated my resolve to disseminate truth overriding lies propagated by them. They underestimated power of internet, the new media. Information is knowledge – and knowledge is power – and power in human hands can lead to very bad and (well used) very good results. Modern age is the age of information. Information plays an important role in each and every sphere of life. It is rightly said that Iraq War was not a war between America and Iraq, but it was a war between two parties, one equipped with information and the other deprived of all information. Hence, the result was a natural outcome. We are living in an age of information revolution. Newspapers, radio […]
CELL DEATH
______________ CELL DEATH: ____________ _ The image shows webbed hand due to apoptosis abnormalities. It is important that inter-digital cell death happens otherwise a webbed limb will develop rather than a five digit limb. _ The image shows paw of a mouse embryo that has been stained with a dye that specifically labels cells that have undergone apoptosis. The apoptotic cells appear as bright green dots between the developing digits. _ As a tadpole changes into a frog, the cells in the tadpole tail are induced to undergo apoptosis; as a consequence, the tail is lost. All the changes that occur during metamorphosis, including the induction of apoptosis in the tail, are stimulated by an increase in thyroid hormone in the blood of a frog. _ The figure shows light micrograph of normal and apoptotic human leukemia cell illustrating chromatin condensation and nuclear fragmentation. _________________________________ _________________________________ Prologue: A vast […]
