Medicinal plants for cancer treatment

Medicinal plants for cancer treatment

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

Novel approaches of biotechnology for cancer treatment

Novel approaches of biotechnology for cancer treatment

This is the era of research and scientific advancements. Biotechnology has a significant role in finding ways for cancer treatment. The novel approaches of plant biotechnology for cancer treatment focus on finding a workable therapeutic strategy. Cancer being one of the deadliest diseases is the

serial analysis for gene expression technique and applications

Serial analysis of gene expression

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

Thermoregulation in endotherms

Thermoregulation in endotherms

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.

Endotherms and energy production

Temperature relations of endotherms

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

Heterotherms and temperature maintenance

Temperature relations of heterotherms

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

ELISA technique a valuable research tool

ELISA technique

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

Ebola virus symptoms and treatment

Ebola virus

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

DNA sequencing technique and applications

DNA sequencing

What is DNA sequencing? ”DNA sequencing is a technique of biotechnology to determine the genome sequence with precise nucleotide order within it.” Determination of precise sequence and order of DNA bases: adenine, guanine, cytosine and thymine is performed. The purpose is to analyze and compare

Plantibodies for therapeutic purposes

Plantibodies

As the name suggests, plantibodies are class of antibodies, which are derived and generated in plants. Although mammalian cells are main source of engineered antibodies production, yet plants also can serve the same purpose as well. Plant biotechnologists aims to manipulate the natural abilities of
