Taxonomy

Taxonomy (arrangement by the rules) is the branch of biology that deals with identification (placement of new organism into a previously described group), nomenclature (the naming of organisms) and classification (ordering of organisms into groups- can be phenetic or phylogenetic) of organisms. Systematics is the process of organizing taxonomic information about organisms into a logical  classification that provides the framework for all comparative studies. It is the scientific  study of biological diversity and its evolutionary history. Systematics and taxonomy are collectively referred to as the systematic biology.

Levels of taxonomy

There are three levels of taxonomy:
Alpha taxonomy : It is concerned with finding, describing and naming of organisms. This is the first and most basic step in taxonomy.
Beta taxonomy : It includes identification of natural groups and biological classes.
Gamma taxonomy : It includes study of evolutionary processes and patterns.

Organisms were first classified more than 2,000 years ago by Greek philosopher Aristotle. He classified organisms as either plant or animal. Modern biological classification began with the eighteenth century Swedish naturalist C. Linnaeus. He established a simple system for classifying and naming organisms. He developed a hierarchy (a ranking system) for classifying organisms that is the basis for modern taxonomy.

Carbonic anhydrase inhibitors (Acetazolamide)

Carbonic anhydrase inhibitors Overview: Acetazolamide, the prototype Carbonic Anhydrase Inhibitors, inhibits carbonic anhydrase and in doing so reduces renal bicarbonate resorption in the proximal tubule. This leads to a direct increase in urinary bicarbonate excretion and secondarily to mild increases in sodium and potassium excretion. Because of its mild effects on electrolytes acetazolamide is a largely safe drug with few adverse side effects but in consequence is rarely used for its diuretic capacity. Mechanism of action: Effects on Bicarbonate:  The pharmacological effects of acetazolamide are due to its inhibitory effect on carbonic anhydrase in the proximal tubule. As discussed in R enal Bicarbonate Excretion , luminal and intracellular pools of carbonic anhydrase in the proximal tubule are critical for resorbing filtered bicarbonate and thus administration of acetazolamide results in significant increases in renal bicarbonate excretion. Because bicarbonate acts a

INTRODUCTION TO IMMUNOLOGY Hello, I am Gajendra Choudhary , welcome to my new blog, The Immune System, New Developments in Research. Do you know how your own body protects you from viruses and other pathogens? Would you be surprised to hear that cancer may also be controlled by your immunity? Every day immunology research aims to understand the mysteries of our bodies and seeks out the seeds for medical application. This course introduces wide ranging content in general immunology fields from basic knowledge to front line research. In particular, I hope that from this course you gain necessary understanding of the new world of immunology, the world opened up by the illustrious immunologists of the past, and the unexplored mysteries that are yet to be explained by experiencing a part of the front line research currently in progress. In this series, we will be learning how the immune system works, in particular how the components of the immune system interact with each other, and

GLYCOLYSIS

GLYCOLYSIS The official spokesperson of carbohydrate metabolism ,'glucose', speaks: "I burn myself to provide fuel to life! Generated through gluconeogenesis by my friends; Engaged in the synthesis of lipids, amini acids; Deranged in my duties due to diabetes melitus." INTRODUCTION Glycolysis is derived from the Greek words (g;lycose- sweet or sugar; lysis -dissolution). Universal pathway in the living cells. This pathway is often referred to as Embden Meyerhof pathway (E.M. pathway). Definition:  Glycolysis is defined as the sequence of reactions converting glucose(or glycogen) to pyruvate or lactate, with the production of ATP. what i am gonna do now is try to make it more interesting for you guys to understand this topic.. it will be a brief conversation between 2 people so lets see how it goes. Fun way to understand glycolysis The conversation between two people to make you guys understand glycolysis more efficiently.
