Your 20-year-old patient is going to start a clinical desensitization program for his allergy to pollen. 1. Describe the pathophysiologic changes to the immune system when exposed to allergens. Allergy is “a hypersensitivity response against an environmental antigen (allergen); the most common are type 1 hypersensitivities (pollen‚ molds‚ fungi‚ certain foods‚ animal dander‚ dust). Others include Type II and Type III (rare but include antibiotics and soluble antigens produced by infectious agents)

It also gives the possibility to save some trees and help the environment. The way genetic modified foods products are produced

Constructing Plant Phylogeny Based on Morphological Characteristics and Molecular Data Phylogeny is the study of evolutionary relationships among groups of living and extinct organisms on earth (Campbell et al.‚ 2011). To show evolutionary relationships‚ a phylogenetic tree (a visual representation of the lineages among organisms) is constructed. All phylogenetic trees are hypotheses that are to be tested‚ modified‚ and tested again. One type of tree‚ known as a

Modifying the World The world has come to a point where anything and everything can be customized; yet never could one have foreseen the customization of life forms. The term "genetically-modified organisms" (GMO’s)‚ is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman‚ 2000). GMO’s offer dramatic promise for some of the greatest challenges of the century‚ however‚ like all new technologies‚ they also possess

The great majority of angiosperms are classified either as monocots or eudicots.Monocot embryos have a single seed leaf (cotyledon)‚ and pollen grains with a single groove while eudicots (true dicots) have two cotyledons‚ and pollen grains with three groove. Monocotyledons have leaf lamina with parallel vein. Their sepal‚ petal arranged in a series of 3s with adventitious root system only. Their vascular bundles scattered in cortex
