Basic Microbiology

Cell membrane (Plasma Membrane) structures and functions

Cell membrane (also called"the plasma membrane (PM) or the cytoplasmic membrane and has been traditionally known as"the plasmalemma) is a membrane in the body which separates the inner part and exterior of cells. It also separates them from their external environment (the extracellular spaces) and shields cells from the elements.

The Beer–Lambert law

The Beer-Lambert Law, also called Beer's law or the Lambert-Beer law or the law of Beer-Lambert-Bouguer, relates to the conduction of light with the characteristics of the material through which light passes.

Radiation Sterilization Types, Mechanism, Applications

Radiation is used to sterilize and decontaminate medical supplies (surgeon supplies, vaccines and drugs) as well as the food and beverage industries. There are two types of radiations available: ionizing or non-ionizing.

Filtration Sterilization Types, Mechanism, Uses

Filtration is the most popular method to sterilize heat sensitive liquid and gases, without exposure to denaturing temperatures. Instead of killing microorganisms that cause contamination the process simply eliminates them. It is the process of choice to sterilize chemical solutions for antibiotics radioisotopes, toxic chemicals or vaccines, as well as carbohydrates, all of which are sensitive to heat.

Centrifugation of blood – Blood Separation

The process of dividing whole blood into its components is known as blood separation. For research purposes, diagnostic and therapeutic reasons as well as research, whole blood may be separated. Scientists may employ several blood separation methods to achieve this.

Sucrose gradient centrifugation

Technique for the characterization and preparation of subcellular particles. A sucrose gradient is used to fill a centrifuge tube of the type swinging-bucket design. The bottom is the most dense, and the top the least dense. The solution is then layered with a suspension of the particles. Centrifugation separates particles in the gradient according their density. The centrifugation is over. After that, the bottom of the tube with sucrose particles of equal density drips into a series receiving tubes.

RCF Centrifugation and RPM Centrifugation

When working with centrifuges you'll encounter two different measurement units that are called the Relative Centrifugal Force (RCF) and the number of revolutions per Minute (RPM). It is essential to be aware of the fact that they are both different.

Scope of Epidemiology

The term epidemiology is derived from the Greek words epi, which means "on or upon;" demos, which means "the common people;" and logy, which means "study. Putting these pieces together yields the following definition of epidemiology: "the study of that which falls upon the common people."
