What is Curcumin?

Curcumin is a component of the Indian spice turmeric (Curcumin longa), a type of ginger. Curcumin is one of three curcuminoids present in turmeric, the other two being desmethoxycurcumin and bis-desmethoxycurcumin. These curcuminoids give turmeric its yellow color and curcumin is used as a yellow food colorant and food additive.

Macular Degeneration Treatment

Although there is no cure for macular degeneration, also known as age-related macular degeneration (AMD), there are several management techniques that can aid individuals with the condition.

What Causes Macular Degeneration?

Macular cells are specialized photoreceptors, both cones and rods, though cones far outnumber rods at this focus. The condition called macular degeneration is caused by a mix of factors, both environmental and hereditary.

What is Macular Degeneration?

This is also called age-related macular degeneration (AMD), as the major risk factor for this is aging. It is an eye disorder characterized by a number of conditions negatively affecting the macula.

Surface Attachment of Biological Elements

A biosensor consists of a bioelement that interacts with an analyte and a transducer that converts the response into an electrical signal. The bioelement is usually an enzyme, antibody or microorganism and the transducer may be optical, acoustic, electrochemical or calorimetric.

Biosensors and Food Industry

Biosensors have extensive applications in the food and agriculture industries. The devices contain a transducer and a biological element, which may be an enzyme, antibody, microbe, or organelle. The biological element (bioelement) interacts with the analyte being tested and the biological response is converted into an electrical signal by the transducer.

Biosensor Applications

Biosensors are devices comprising a biological element and a physiochemical detector that are used to detect analytes. These instruments have a wide range of applications ranging from clinical through to environmental and agricultural. The devices are also used in the food industry.

Biosensor Principles

The term “biosensor” is short for “biological sensor” and is a device made up of a transducer and a biological element that may be an enzyme, an antibody, or a nucleic acid. The biological element or bioelement interacts with the analyte being tested and the biological response is converted into an electrical signal by the transducer. Every biosensor has a biological component that acts as the sensor and an electronic component that detects and transmits the signal.

What are Biosensors?

The term “biosensor” is short for “biological sensor.” The device is made up of a transducer and a biological element that may be an enzyme, an antibody or a nucleic acid. The bioelement interacts with the analyte being tested and the biological response is converted into an electrical signal by the transducer. Depending on their particular application, biosensors are also known as immunosensors, optrodes, resonant mirrors, chemical canaries, biochips, glucometers and biocomputers.

Hunter Syndrome Treatments

Hunter syndrome is an inherited disorder where glycosaminoglycans (GAGs) build up in cells of the body due to a deficiency of the enzyme iduronate-2-sulfatase.

Hunter Syndrome Biochemistry

Numerous biochemical reactions support key functions in the human body. These functions include energy production, communication within the body, growth, development and the fight against infection. Another important function is the breakdown of large biomolecules. A fault in the breakdown of these molecules is the pathological mechanism behind hunter syndrome and other storage diseases.

Hunter Syndrome Symptoms

The symptoms of Hunter syndrome vary from person to person. While one individual may have mild symptoms, another can develop severe complications. The symptoms of this condition are not present when a child is born, but start to develop after the first year of life. If symptoms start to manifest early (between 2 and 4 years of age), they are generally more severe.

Hunter Syndrome Diagnosis

A diagnosis of Hunter syndrome is usually suspected in young people who display signs and symptoms of the condition. Characteristic changes in the facial features provide the main initial warning that a child may have Hunter syndrome.

Hunter Syndrome Genetics

Hunter syndrome is a lysosomal storage disease that is inherited in an X-linked recessive manner and therefore mainly affects male offspring.

What is Hunter Syndrome?

Hunter’s syndrome is a lysosomal storage disorder caused by a deficiency in the enzyme iduronate-2-sulfatase (I2S). The disease was first described in 1917 by physician Charles A. Hunter (1873-1955), a Scottish national who had a medical practice in Winnipeg, Manitoba. The disease is inherited in an X-linked recessive manner and usually affects males.
