VULNERABLE PLAQUE

Vulnerable Plaque: ____ ____ Prologue: Worldwide more than 17 million people die every year from cardiovascular disease (CVD) with this number projected to increase to over 23 million by 2030. The vast majority of acute ischemic vascular events occur in relation to an underlying atherosclerotic plaque. Atherosclerotic plaque represents the hallmark lesion of atherosclerosis. Plaque rupture is the dominant initiating event, responsible for 60–70% of acute coronary syndromes (ACS), while plaque erosion is responsible for most of the remainder. Irrespective of the mechanism, the consequence is exposure of a thrombogenic substrate to circulating blood. This in turn triggers platelet aggregation and the coagulation cascade which compromises vascular blood flow resulting in downstream end-organ ischemia and infarction. These events occur abruptly and often without warning. Despite major advances in treatment of coronary artery disease patients, a large number of victims of the disease who are apparently healthy die suddenly without prior […]

ELECTRONIC VOTING

Electronic Voting: _____ _____ Prologue: Voting is the bridge between the governed and the government. The right to vote freely for the candidate of one’s choice is of the essence of a democratic society. Every voter’s vote is entitled to be counted once. It must be correctly counted and reported. The Voting System of a country consists of certain regulations which define how the preference of people is collected and how outcome of the polling process is indicating the will of people. A popular quote says that “It’s not the people who vote that count, it’s the people who count the votes.” Elections are a defining feature of democratic government, but all too frequently, we take the actual mechanics of the election for granted. We speak at length of such issues as who is allowed to vote, how campaigns are conducted, and how they are financed, but most people’s understanding […]

FACIAL RECOGNITION (TECHNOLOGY)

Facial Recognition (Technology): _____ _____ Prologue: Faces are special. Days after birth, an infant can distinguish his/her mother’s face from those of other women. Babies are more reliably engaged by a sketch of a face than they are by other images. Though human faces are quite similar in their basic composition, most of us can differentiate effortlessly among them. A face is a codex of social information: it can often tell us at a glance, someone’s age, gender, racial background and mood. The human brain is often less reliable than digital algorithms, but it remains superior at facial recognition. At the airport, when a scanner compares your face with your passport photo, the lighting is perfect and the angle is perfect. By contrast, an average human can recognize a family member from behind. No computer will ever be able to do that. Though we may take for granted our brain’s […]

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 […]

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. […]
