Article on Niosomes added.

Author: Akul Mehta
Abstract: Niosomes are a novel drug delivery system, in which the medication is encapsulated in a vesicle. The vesicle is composed of a bilayer of non-ionic surface active agents and hence the name niosomes. The niosomes are very small, and microscopic in size. Their size lies in the nanometric scale. Although structurally similar to liposomes, they offer several advantages over them. Niosomes have recently been shown to greatly increase transdermal drug delivery and also can be used in targeted drug delivery, and thus increased study in these structures can provide new methods for drug delivery.

Notes for liposomes added in the Pharmaceutics and Pharmaceutical technology section on Pharmaxchange.info.
Click here to view the notes in the section.
Author: Presented by Dr. Abha Doshi (Principal of MET- Institute of Pharmacy, Bandra), Assisted by Akul Mehta.
Description: A presentation on liposomes with slides covering everything you would want to know about this novel drug delivery system. It contains information on what are liposomes, advantages of liposomes as a drug delivery system, structural components of liposomes (phospholipids and cholesterol) and the types of ingredients which can be used to make liposomes. It also contains information on how liposomes are prepared and the various methods to prepare them, the classification of liposomes, and characterization and quality control tests that are performed on liposomes.
Number of Slides = 113 (in pdf format since 2 slides fit per page it comes to 113 pages)

New Animations added in biotechnology page.

http://pharmaxchange.info/animations_biotechnology.html

The following animations are added:
1) Recombinant DNA Technology
2) DNA Fingerprinting Techniques
3) Polymerase Chain Reaction (PCR)

Recombinant DNA Technology
Description - A 3D animation illustrating the process by which a protein is mass-produced using spliced DNA and bacterial replication using Plasmids. DNA recombinant technology is used to produce proteins using bacteria. The bacteria being easier to grow than actual animals, proteins can be mass produced using them. This animation shows how exactly using the DNA from which the protein can be made, a plasmid is generated which is a recombinant DNA plasmid, which when reintroduced into the bacteria promotes the bacteria to synthesize the protein.

DNA Fingerprinting Technique
Description - An animation showing how DNA Fingerprinting is done. DNA fingerprinting is used a lot in forensic studies to find criminals. As the DNA of a person is unique, DNA fingerprinting can be used to identify people. In these times of identity theft, terrorism, and the TV criminology craze, learn just how genetic fingerprinting occurs.

Polymerase Chain Reaction (PCR)
Description - This animation shows what PCR or Polymerase Chain Reaction is and how it is done. It is a very informative animation showing the technology and the concepts used to perfom PCR.

Asthma and COPD (Chronic Obstructive Pulmonary Disease)
Description: A detailed video showing what happens in asthma and other COPD (Chronic Obstructive Pulmonary Diseases). Mainly shows what goes in asthma in the lungs and at a cellular level the changes which takes place. Shows the different types of treatments available. Then goes on to cover a little bit of COPD as well.

Diuretic Action In The Kidney
Description - A very detailed animation showing the working of the kidney and the nephron and the mechanism of action of various diuretics. It is a long 8 minute 47 second animation showing the molecular mechanism of the working of the nephron and the drugs which act on the various different regions of the nephron. It shows the detailed mechanism of action of the diuretics such as the loop diuretics, the potassium sparing diuretics, and the thiazide diuretics.

Animation for Parkinson's Disease has been added in the Animations page under the New CNS Disorders section. An excellent animation showing what causes Parkinson's Disease and how parkinsonism is tackled now. It shows what goes wrong in the substantia nigra part of the brain and how acetylcholine (ACH) and Dopamine balance is lost to cause the disease. It talks of the symptoms of the disease, and treatments currently used for the treatment of the disease. View it at http://pharmaxchange.info/animations_cns.html

Classroom Presentation on Genetic Engineering:
Slides used by Prof. Vijaya Patil of MET Institute of Pharmacy to teach the topic of Genetic Engineering. It has everything needed to understand the basics of Genetic Engineering including its application, use of restriction enzymes and naming of restriction enzymes, steps in synthesizing a recombinant protein, DNA cloning, cleaving DNA and generating DNA fragments (using methods like mechanical shearing, shotgun method, restriction digest method, hybridization method, reverse transcriptase, and chemical synthesis methods), producing recombinant DNA/ insertion of target DNA into vectors, and Vectors such as plasmids, bacteriophages, cosmids, phage vectors, phasmid, yeast cloning vectors, bacterial and human artificial chromosomes, Shuttle vectors, and vectors used in plants - Ti plasmids. It also covers topics on screening techniques, and library screening.
