ATHEISM

ATHEISM: _____ Caveat: This article has no desire to insult anybody in any way at all. If anyone feels offended, it is a regrettable misunderstanding because the criticisms are aimed at the objectives of the belief, never at believers as individuals. I recognize and respect right of all individuals to believe in their faith and their God if that helps them to live better life in the brief period of human existence allotted to them. But religious beliefs and doctrines become dangerous if they threaten the liberty and the integrity of the individual or of the society. _____ _____ Prologue: According to Psalm 14 of the Bible, people who don’t believe in God are filthy, corrupt fools, entirely incapable of doing any good. Before the 18th century, the existence of God was so accepted in the western world that even the possibility of true atheism was questioned. This is called […]

NIPAH

Nipah: _____ Figure above shows burial of a victim of Nipah virus in Kozhikode, India. _____ Prologue: An outbreak of probable encephalitis hit Siliguri, India in 2001. All hell broke loose when a cardiologist by the name of Dr Ajit Maity and a nurse associated with Medinova Florence Nursing Home fell victim to this disease. It was reported that both had contracted it while treating a patient. A few other doctors, nurses and paramedics were taken severely ill in another hospital. Ten among those infected medics later died. Soon, Siliguri started resembling a ghost town. The roads were deserted, shops shut and schools were closed for a week. There was misinformation circulated based on rumour and gossip. But worst of all was that some doctors secretly fled. Some doctors were apprehended at Jalpaiguri Railway Station and Bagdogra Airports by citizens before they could slip away. Red-faced politicians had flown in […]

ORGAN DONATION & TRANSPLANTATION (ODT)

  Organ Donation & Transplantation (ODT): ____ Jemima Layzell died of a brain aneurysm in 2012 and her organ donations have helped eight people including five children. ____ Prologue: In 1894, the surgeon Otto Lanz (1865–1935) warned his colleagues not to scoff at a treatment “which aims at replacing the organ that has lost its function in the organism”. Today, no one would doubt the seriousness of a surgeon who treats a disease by replacing an organ. However, it was only around 1900 that the idea of organ replacement became self-evident. The introduction of antibiotics, massive vaccinations of the general population to prevent infectious diseases, and organ transplantation may be considered the miracles of twentieth century medicine. Organ transplantation is the best therapy for terminal and irreversible organ failure. Transplantation has given many a new lease on life and, to many more, an extension that would have otherwise been impossible. […]

Many scientists and students signed a petition calling upon him to withdraw his remarks. Three science academies […]

OXYGEN THERAPY

Oxygen (O2) Therapy: _____ While we inhale 21% of oxygen and 0.04% of carbon dioxide, we exhale 17% of oxygen and 4% of carbon dioxide. _____ Prologue: Oxygen (O2) is a vital element in human survival and plays a major role in a diverse range of biological and physiological processes. Oxygen therapy means using an oxygen cylinder or a machine to breathe in air that contains more oxygen than normal. Oxygen is widely available and commonly prescribed by medical and paramedical staff.  In medical practice, it is among the most universally used agents for the treatment of critical illness and part of the routine treatment in acute shock and emergency medicine. Proper application of oxygen therapy and airway management is lifesaving. In the absence of O2 (hypoxia), cellular respiration ceases and irreversible cellular injury and death occur within minutes. Administered correctly it may be lifesaving. However, renaissance physician Paracelsus noted: […]
