Antibiotic Resistance is a term that appears to be like some super terms used in some science fiction movies. But this term is something from which we should be afraid of because antibiotic resistance and spread of drug-resistant pathogens are one of the most serious and dangerous threats to public health in this 21st century. Continue reading What are the different Causes of Antibiotic Resistance?
From the beginning of time, people have tried to understand aging and processes associated with the biology of aging. Many scientists believe that aging results from the repetitive damage caused to our body cells. The everyday metabolic activities that usually sustain our life but also create “metabolic stress”, which over time, results in damage to our bodies. Some of these metabolic activities result in the production of radicals and which may cause harmful damage to our body cells. Continue reading Free Radicals: What is their role in making us old?
Several strategies can be used to prevent the emergence of Antibiotic Resistance.
- We can use antibiotics in reasonably high concentrations to destroy susceptible bacteria and most spontaneous mutants, which may arise during the treatment period. Continue reading How can we fight against Antibiotic Resistance?
Bacteria often become resistant through different kinds of mechanisms. One kind of mechanism is never confined to any specific class of antibiotics. Different resistance mechanisms are used in different bacteria to confront the same antibiotics.

Fifty years ago people believed that the war of humankind against the infectious diseases was virtually over and science had won over infectious diseases such as pneumonia, whooping cough, polio and small pox with the help of antibiotics, vaccines, and some aggressive public health campaigns.
Transplantation is a process of picking some cells, tissues or organs from one site and placing them at another site in same or different individuals.
