Anti-inflammatory and analgesic properties of Lavandula angustifolia
Method: There are different methods for the analysis of oils from the Lavandula spp. The standard method, however, is the gas chromatography with mass spectrometry (GC/MS), which has been adopted by the researchers in the article. Another method is the infrared spectroscopy (GC/IRFT). Both qualitative and quantitative analyses were carried out. The analyses clearly identified the chemical components of the essential oil and their percentage. The main constituents of Lavender oil are linalool

Role Of Notch Signaling In Oncogenesis
Interaction between the receptor and ligand induces a couple of proteolytic cleavages causing the release of the intracellular domain part of the receptor from the cell membrane. This interaction is mediated by consecutive enzymatic reactions. The intracellular domain then translocates to the nucleus part of the cell and forms a complex with a protein called RBPJ. This reaction leads to displacement of a histone deacetylase-co-compressor complex from the RBPJ protein molecule and then inclusion

Final project Draft
As human populations grew, so did the necessity to expand for shelter become more apparent. Towns would expand to become cities, and cities would become sprawling metropolis. The materials needed to pursue this task would require so many natural resources to get this done. Many trees would require being lumbered or cut down to construct buildings, houses and fixtures for shelter and commercial use. At the same time, many natural wilderness areas would have to be cleared out to provide land for

Human Nervous System
Perhaps the simplest example of what the Central Nervous system does is in the fact that as soon as someone’s hand touches a hot object, the body reacts within milli seconds and the bodies reflex is to draw back the hand immediately. Behind this simple activity are sensory tasks performed by the Central Nervous System whereby the hot sensation registered by the hand is transmitted to the brain, is decoded by the brain and the brain instructs the specific part to perform the action of drawing

Prokaryotes - Facilitation of Chemical Recycling
Prokaryotes form a basic element in the life of plants. Every chemical is a nutrient to cycle in the biosphere. The prokaryotes then decompose elements from the atmosphere into inorganic molecules. The decomposed substances are further broken down to release carbon and nitrogen into the environment allowing them to be absorbed back by the plants.

Chronic bronchitis
Chronic bronchitis patients are vulnerable to respiratory infections. This is due to the irritating substances they inhale and due to the fact that the substances are chronic, they lead to impaired mucociliary clearance. As nonciliated metaplastic cells replace ciliated epithelium and the mucous secreting goblet cells become proliferated, the result is impaired mucociliary clearance (Arcangelo & Peterson, 2006). Chronic bronchitis mostly affects adults and it is mostly found in men than in

How Biomedical Research Using Animals has Benefited a Pet, You, or Someone You Know
The development of these drugs has been possible through intensive research that has been done on animals (rats) (Animal Research Info). It is the identification of estrogen receptor (ER) in the laboratory that has made it possible to describe the target site specificity of estrogen action in breast cancer (Jensen and Jordan 1). In the 1970s, there was consideration of the use of ER as a target for therapeutics. At this time, tamoxifen was a pioneer medication to be created and thought safe for

The pathology of Parkinson's disease, and how to counteract it
The present research has identified that when a patient is affected by Parkinson’s disease, his or her circuitry balance is normally lost. Such loss comes about as a result of dopamine depletion. The parts that are affected in this case are the indirect and direct pathways whose nuclei are responsible for inhibiting the thalamus. When the activities of these nuclei found in the pathways increase, the inhibition process is consequently increased reducing the normal movement of a person.
