Epileptic Seizure Diagnosis

Seizures are a symptom of epilepsy. It is important to diagnose which type of epilepsy a person has in order to decide on the optimal treatment approach.

Epileptic Seizure Symptoms

Epileptic seizures or fits are caused by abnormal electrical activity in the brain. Electrical impulses act on several areas of the brain affecting muscular function, sensation and awareness.

What is a Seizure?

Seizures are caused by abnormal electrical activity in the brain. In the healthy brain, electrical and chemical signals are fired between nerves called neurons to drive the brain's ability to think, feel and send instructions to parts of the body, such as the muscles. Seizures occur when this electrical system in the brain malfunctions.

Collagen Types and Linked Disorders

There are 29 genetically distinct collagens present in animal tissues. Collagen types I, II, III, V and XI self-assemble into D-periodic cross-striated fibrils. Here the D is approximately 67 nm and there is characteristic axial periodicity of collagen. These form the most abundant collagens in vertebrates.

Collagen Fibrillar Structure

The collagen molecule or the tropocollagen contains subunits that assemble without assistance and has regular ends that form larger arrays in the extracellular spaces of tissues.

Collagen Molecular Structure

The collagen molecule, also known as the “tropocollagen”, is part of larger collagen aggregates such as fibrils. The whole molecule is approximately 300 nm long and 1.5 nm in diameter.

What is Collagen?

Collagen is a protein made up of amino-acids, which are in turn built of carbon, oxygen and hydrogen. Collagen contains specific amino acids – Glycine, Proline, Hydroxyproline and Arginine.

Metastasis Treatment

Metastasis denotes distant spread of cancer from the primary organ. Treatment of any form of cancer is dependent on whether or not it has spread to distant organs. If the cancer spreads to other tissues and organs, it may decrease a patient's likelihood of survival. Cancer of the testes and thyroid however when metastasized may still be curable.

What is Metastasis?

Metastasis is a complex process that involves the spread of a tumor or cancer to distant parts of the body from its original site. However, this is a difficult process. To successfully colonize a distant area in the body a cancer cell must complete a series of steps before it becomes a clinically detectable lesion.

Antibody History

The earliest reference to antibodies was from Emil von Behring along with Kitasato Shibasaburo in 1890 who found the presence of a neutralizing substance in the blood that could counter infections. They developed the serum against diphtheria. This they did by transferring serum produced from animals immunized against diphtheria to animals suffering from it. This serum could cure the infected animals. Behring was awarded the Nobel Prize for this work in 1901.

Antibody Structure

Antibodies are proteins with around 150 kDa molecular weight. They have a similar basic structure comprising of four polypeptide chains held together by disulfide bonds. These four polypeptide chains form a symmetrical molecular structure. There is a hinge in the center between heavy chains to allow flexibility to the protein. There are:
