Lichen Essays

Lichen planus (LP) can occur on the skin alone; h. However, it is also seen inside the oral cavity, on the scalp, nails and the genital mucosa. Symptoms of lichen planus may wax and wane. They may increase during periods of trauma, or during stress and anxiety. Cutaneous LP Lichen planus is a papulosquamous skin disease which produces intense itching (pruritus). It consists of lesions which are characterized by six P’s: • Pruritic • Purplish • Planar • Polygonal • Papules • Plaques The rash

Background: Lichen planus (LP) is an inflammatory dermatosis with an unknown etiology. Although usually lichen planopilaris (LPP) occurs within terminal hair follicles; there are some reports of concomitant involvement of vellus hairs that present with papular eruption of the face along with frontal fibrosing alopecia (FFA). Method: Here we report three patients presented with asymptomatic facial papules with histologic examination in consistence with lichen planopilaris. Result: Based on these cases

Frankenstein is a book filled with puzzling hidden connections that can relate to what majority of us go through in American society today. Quotes throughout the novel create a piece of inspiration that we can look up to when discovering similar times. The diction revels pros and cons on how Starting off the novel At the trial for Justine Moritz, Elisabeth states vindication by saying “It may therefore be judged indecent in me to come forward on this occasion, but when I see a fellow creature

and Fryday A. 2009. Lichens and bryophytes of the alpine and subalpine zones of Katahdin, Maine, I: Overview, ecology, climate and conservation aspects. The Bryologist 112(4): 651-672. Maine’s tallest peak, Katahdin, is covered by vast amount of the alpine and subalpine ecosystem and vegetation. The region contains a variety of bryophytes and lichen that have been around since the mid-1800s and for about 16 days from 2001 to 2004, researchers have been surveying the lichens and bryophytes of the

2-diphenyl-1-picryl-hydrazyl-hydrate) radical is used free radical method is an in antioxidant assay forwas used to evaluate measured the free radical scavenging activity of the lichen extract [8]. Two millilitreers of 0 .05 mg/mL methanol solution of DPPH radical in the concentration of (0 .05 mg/mL) and 1 mL of the lichen extract (1 mg/mL) were placed in cuvettes. The mixture is storewas stored stand at room temperature for 30 min. Then, the absorbance was measured at 517 nm in a spectrophotometer

Did you know the Musk Deer have fangs? Well they do and I will talk about that more later. I will write about the Musk Deer. I will talk about all of the weird and normal things about the Musk Deer. I will write about the appearance of the Musk Deer, the diet and habitat of the Musk Deer, and interesting facts about the Musk Deer. First, the appearance. The Musk Deer has a brownish fur coat. It has long legs and they have pouches, and they have fangs. Let 's talk about their legs, I went on Encyclopedia

book Wild Trees. I learned to distinguish technical writing elements from this assignment. For example, I chose to find examples of mechanism description for this assignment. I found the description of lichens as one of the example on page 24 of the book. I was able to show how the description of lichens is a mechanism description, described each part such as fungus, alga, and cyanobacterium and each of their function. Through this assignment, I understood how to distinguish technical writing elements

The Ordovician period was a time when different parts of the Earth changed and new life forms were discovered. This period occurred after the Cambrian period during what is called the Paleozoic era (540 to 248 mya). Some types of animals discovered during this period are said to be the first findings known to later transform during future time periods. Different varieties of plants were also discovered, mostly found growing in the water. First, many things contributed to the environment the Ordovician

Coast Mountains spend themselves as rain at lower elevations and as snow in the high country. Some parts of the forest receive more than 200 inches of rain each year. The forest that grew up on these islands is a mosaic of muskeg, alpine scrub and lichen-draped conifer rainforest. It is dominated by x Gustav Tjgaard western hemlock, interspersed with Sitka spruce and small amounts of western red cedar and prized Alaska yellow cedar. The forest floor is a nearly impenetrable jumble of toppled trees

that the cell was the simplest form of matter, but we understand today that the cell has parts of its own and is incredibly complex. Darwin also thought that every organism evolves, and is self-dependent, but today we know of an organism called a lichen that is dependent on an alga (a form of algae) for survival.

In Annie Dillard’s non-fiction narrative essay Total Eclipse, which was taken from the collection called Teaching a Stone to Talk, she gives a detailed description about her experience of witnessing a total eclipse phenomenon with her then-husband Gary and also some thoughts about humanity that she gained from the experience. Unlike many other non-fiction writers, Dillard likes to bring fictional elements to her writing which adds on to the unconventional themes and ideas that she incorporates in

In today’s society we face a substantial issue at hand, that being climate change. Due to the rapid increase in temperature in relation to the increase in greenhouse gases emitted a vast array of different issue arise. When we look to see the effects of these hazards it is good to start in the Polar Regions. In this paper, I will discuss the factors of both Antarctica and Central Texas and their correlation of climate change with its effect on biomass/biodiversity. Antarctica is drastically different

particular environment. In this assay I will focus on the biome called Tundra. Tundra is defined as a treeless area away from the timberline in high-latitude regions, having a permanently frozen subsoil and supporting low-growing vegetation such as lichens, mosses, and shrubs. Tundra is the coldest of all the biomes. Tundra is derived from the Finnish word “tunturia”, meaning treeless plain. It is well-known for its frost-made landscapes, extremely low temperatures, little precipitation, poor nutrients

Annotated Bibliography Alpine Fellfield Resource 1: Literature Review Dibble AC, Miller NG, Hinds JW and Fryday AM. 2009. Lichens and bryophytes of the alpine and subalpine zones of Katahdin, Maine, I: Overview, ecology, climate and conservation aspects. The Bryologist 112(4): 651-672. A vast region of Katahdin Peak, Maine has been explored to analyze the different lichens and bryophytes uniquely found in this ecosystem. This literature review reflects on the history of the botanical exploration

They also only stand around 3 feet not counting its neck. That’s right their necks add about 2 feet. Now on to its diet they only eat plants that means that they are herbivores. All the foods in their diet are right here. Grass, forbs, hay, lichens, tree foliage, shrubs, and shoots. Along with being in captivity they tend to eat grains and carrots. They also eat the leaves off of trees just like Now on to where they

Evolution is a very controversial topic among scientists and religious supporters who have very different perspectives about how the Earth has evolved from what it was then to what it is now. The theory that scientists find most factually correct is that current species were descents from the original species that date to prehistoric times. Over a long period of time they had acquired new characteristics and physical traits to help them adapt in their ever changing environments. To try and experience

Earth 2.0 Earth 2.0, that is crazy. I have seen a video about terraforming mars into the next earth. I didn’t know if it’s possible. Then I heard we are doing a research essay in English class. Mars is a red planet. It is right next to us. I don’t know much about mars, but I did some research about terraforming mars. It’s crazy we are thinking about terraforming mars. We have the technology to build the machines to create oxygens. We already have the greenhouse and science are quickly evolving for

DYEING Dyes are coloring materials used in dyeing textiles. Other hand it can be defined as a substance which may be natural or synthetic use to change or add color to the textile materials. They are incorporated into the fiber by chemical reaction, absorption, or dispersion. Dyes differ in their resistance to sunlight, perspiration, washing, gas, alkalizes, and other agents; their affinity for different fibers; their reaction to cleaning agents and methods; and their solubility and method of application

During the trip to Wekiva State Park we got to see some of the most dramatic habitat and hydrological changes yet. Starting out at the spring and watching the water being forced out from deep within the aquifer. The cavern where the spring is located is only approximately 20 feet deep and has been restricted to divers for many years due to the inherent hazard of cave diving. A constant 72 degrees year round, Wekiva Springs provides about 42 million gallons of some of the cleanest water you will

Epigenetics is the study of inheritable changes in gene expression (active versus inactive genes) that do not involve changes to the underlying DNA sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes. [1] The change in gene expression is inherited by the following generations but is reversible. A gene is a particular sequence of DNA that will code for a specific individual’s characteristics such as their hair colour or eye colour. Phenotype:
