Cancer is one of the deadliest diseases killing a large number of people worldwide. Over the course of year, scientists have identified the molecular basis of cancer.Despite considerable efforts, cancer persists to be an aggressive killer worldwide. Hence a constant demand is required to develop new, efficacious and affordable methods to treat this disease. Chemotherapy, …
Botulism is severe infectious disease caused by neurotoxin botulinum. An infectious bacterial species Clostridium botulinum release this toxin. Botulisms food poisoning is one common illness which may lead to severe and fatal results. Moreover, botulism often leads to paralysis if remain untreated and undiagnosed. Botulinum is a neurotoxin, which disrupts brain cells and their functioning. …

Cancer being one of the deadliest diseases is the major public health concern worldwide. What basically cancer is? Cancer …
Parkinson’s disease is nervous disorder. It affects the nervous coordination which eventually affects the body and muscle movement. The initial signs are tremors in hand and later it leads to stiffness and slowing of muscle and body movements. This is a progressive neurodegenerative disorder in which the symptoms gradually get worse. According to reports by …
Serial analysis of gene expression (SAGE) is a technique used to provide a library of the mRNA sequences (transcripts) of the sample in the form of small tag sequences or the express sequence tags (EST), each of which correspond to a particular transcript. EST is short sequences of DNA. These are useful for identifying the …
Endotherms regulate and maintain their internal body temperature within a homeostatic range. This phenomenon is termed as thermoregulation. These mechanisms vary according to the requirements. For instance, these are either for heat production or heat loss to maintain the internal body temperature of the organisms. How endotherms behave and what basic strategies they adapt for …
In birds and mammals which are homeothermic endotherms, there body temperature is regulated closely by homeostatic mechanisms. These mechanisms regulate loss of heat and heat production. Thus, they maintain constant body temperature, independent that of temperature of environment. In endotherms, the core temperatures are reserved constant between 37°C-38°C in mammals and 40°C for birds. On …
Animals cope with fluctuations in temperature by different ways. One of the basic ways is by generating and trapping the heat internally in order to maintain constant body temperature despite of the different changes in the external environment. Organisms can be heterotherms, endotherms or ectotherms depending on from where they get heat and how they …
Heat stroke is a condition when the body temperature rises more than what it can endure. Overheating usually happens when you have prolonged exposure to sun or doing a strenuous physical activity. To be exact, body temperature more than 104 F which is 40 degree Celsius causes heatstroke. The hypothalamus in our brain can feel …
Enzyme linked immunosorbent assay ELISA is an assay technique of biotechnology for detection of various enzymes, proteins, antibodies and hormones. The detection is based on antigen-antibody interactions. Antigen molecules are immobilized on surface of 96 wells polystyrene plate. Adding antibody solution on plate results in antigen-antibody complexes. Assessing the activity of conjugate enzyme (attached with …
HIV/AIDS is a deadly contagious disease in humans. HIV refers to Human Immune Deficiency Virus. This HIV virus causes Acquired Immune Deficiency Syndrome AIDS in humans which is in fact the last stage of viral infection. The patients’ immune system gets weak and unable to fight the infections and pathogens. Consequently, the person dies due …
Every profession comes with certain degree of sincerity and responsibility. But the medical profession is something which demands even more care, responsibility and sincerity. Medical malpractice is becoming a global threat and menace. It happens due to negligence and irresponsible behavior of health care providers. Their negligence can bring someone a lifetime of misery and …
Zaire Ebolavirus or commonly known Ebola virus belongs to genus ebolavirus. It causes severe and fatal Ebola virus disease or Ebola hemorrhagic fever in humans. Primarily, animals spread this virus to humans and later human to human interaction spreads it to others. The average mortality rate is 50%. However, this percentage rose up to 90% …
