G protein-coupled receptors (GPCR)

Introduction: G protein-coupled receptors (GPCR) are a well-known broad group of membrane receptors which are among the most significant therapeutic targets. Activation of GPCRs by extracellular stimuli, initiates the signal transduction that eventually leads to the response. Crystal structure of GPCRs by crystallization protocol is...

Different types of white blood cells

The hydrogen ions then combine with hemoglobin and the bicarbonate ions go into the plasma. Seventy percent of the CO2 is removed in this way. Seven percent of the CO2 is dissolved in the plasma. The remaining 23 percent of the CO2 combines directly with...

The role of T cells in the Immune system

MHC class I molecules present peptides which bind to the T cell receptors of cytotoxic T lymphocytes. These are found on the cell surface of almost all nucleated cells in the body which enable the T cells to distinguish between “self” and foreign antigens. This...

4 major types of blood: A, B, AB, and O

There are 4 major types of blood A, B, AB, and O. What blood you have depends on what antigen is on red cells and what antibody in the plasma; more on that later. Blood type is hereditary and which one you have, depends on...

Mitosis: phases and functions

Mitosis is a key component of every cell’s life. All Eukaryotic cells are required to go through mitosis, except for sperm and egg cells. Mitosis creates two daughter cells from one cell. Additionally mitosis creates genetically identical offspring, this means that all of the cells...

Fiber analytical schemes

Besides food manufacturers, epidemiologists, scientists, and dietitians need data on the fiber content of foods (8). Yet attempts to define and standardize methods to measure dietary fiber remain contentious. Dietary fiber is essentially the undigested carbohydrates in the diet (9). These carbohydrates may be fermented...

Report On The Experiments On Light Incubation

In the first experiment, our results supported the hypothesis that T. zuluensis reacts differently on exposure of light. However, it did not grow best in the darkness. The growth of pathogen was significantly different under different volumes of light and dark incubation. The growth under...
