Caster (maggot)
A maggot is the larva of a fly (order Diptera); it is applied in particular to the larvae of Brachycera flies, such as houseflies, cheese flies, and blowflies, rather than larvae of the Nematocera, such as mosquitoes and crane flies. Entomology "Maggot" is not a technical term and should not be taken as such; in many standard textbooks of entomology, it does not appear in the index at all. In many non-technical texts, the term is used for insect larvae in general. Other sources have coined their own definitions; for example: "The term applies to a grub when all trace of limbs has disappeared" and "Applied to the footless larvae of Diptera".Smith, John. BExplanation of terms used in entomology Brooklyn Entomological Society, 1906. Additionally, in ''Flies: The Natural History and Diversity of Diptera'', the author claims maggots "are larvae of higher Brachycera ( Cyclorrhapha)." Maggot-like fly larvae are of significance in ecology and medicine; among other roles, vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decomposing Possum
Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere. Bodies of living organisms begin to decompose shortly after death. Animals, such as worms, also help decompose the organic materials. Organisms that do this are known as decomposers or detritivores. Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition. The science which studies decomposition is generally referred to as ''taphonomy'' from the Greek word ''taphos'', meaning tomb. Decomposition can also be a gradual process for organisms that have extended periods of dormancy. One can differentiate abiotic decomposition from biotic decomposition (biodegradation). The former means "the degradation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tephritidae
The Tephritidae are one of two fly families referred to as fruit flies, the other family being the Drosophilidae. The family Tephritidae does not include the biological model organisms of the genus ''Drosophila'' (in the family Drosophilidae), which is often called the "common fruit fly". Nearly 5,000 described species of tephritid fruit fly are categorized in almost 500 genera of the Tephritidae. Description, recategorization, and genetic analyses are constantly changing the taxonomy of this family. To distinguish them from the Drosophilidae, the Tephritidae are sometimes called peacock flies, in reference to their elaborate and colorful markings. The name comes from the Greek τεφρος, ''tephros'', meaning "ash grey". They are found in all the biogeographic realms. Description For terms see Morphology of Diptera anTephritidae glossary Tephritids are small to medium-sized (2.5–10 mm) flies that are often colourful, and usually with pictured wings, the subcostal ve ...

Common Green Bottle Fly
The common green bottle fly (''Lucilia sericata'') is a blowfly found in most areas of the world and is the most well-known of the numerous green bottle fly species. Its body is in length – slightly larger than a house fly – and has brilliant, metallic, blue-green or golden coloration with black markings. It has short, sparse, black bristles (setae) and three cross-grooves on the thorax. The wings are clear with light brown veins, and the legs and antennae are black. The larvae of the fly may be used for maggot therapy, are commonly used in forensic entomology, and can be the cause of myiasis in livestock and pets. The common green bottle fly emerges in the spring for mating. Description The defining characteristic of ''L. sericata'' and the one most used when identifying the adult fly is the presence of three bristles on the dorsal mesothorax, located on the middle of the back of the fly. ''L. sericata'' is almost identical to its conspecific, '' L. cuprina,'' and ident ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disinfect
A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical or chemical process that kills all types of life. Disinfectants are generally distinguished from other antimicrobial agents such as antibiotics, which destroy microorganisms within the body, and antiseptics, which destroy microorganisms on living tissue. Disinfectants are also different from biocides—the latter are intended to destroy all forms of life, not just microorganisms. Disinfectants work by destroying the cell wall of microbes or interfering with their metabolism. It is also a form of decontamination, and can be defined as the process whereby physical or chemical methods are used to reduce the amount of pathogenic microorganisms on a surface. Disinfectants can also be used to destroy mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maggot Therapy
Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound, (debridement) and disinfection. There is evidence that maggot therapy may help with wound healing. Medical uses Maggot therapy improves healing in chronic ulcers. In diabetic foot ulcers there is tentative evidence of benefit. A Cochrane review of methods for the debridement of venous leg ulcers found maggot therapy to be broadly as effective as most other methods, but the study also noted that the quality of data was poor. In 2004, the United States Food and Drug Administration (FDA) cleared maggots from common green bottle fly for use as a "medical device" in the US for the purpose of treatment of: * Non-healing necrotic skin and soft tissue wounds * Pressure ulcers * Venous stasis ulcers * ...

Medical Practitioner
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pathology
Pathology is the study of the causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be " pathophysiologies"), and the affix ''pathy'' is sometimes used to indicate a state of disease in cases of both physical ailment (as in cardiomy ...

Debridement
Debridement is the medical removal of dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue. Removal may be surgical, mechanical, chemical, autolytic (self-digestion), and by maggot therapy. In podiatry, practitioners such as chiropodists, podiatrists and foot health practitioners remove conditions such as calluses and verrucas. Debridement is an important part of the healing process for burns and other serious wounds; it is also used for treating some kinds of snake and spider bites. Sometimes the boundaries of the problem tissue may not be clearly defined. For example, when excising a tumor, there may be micrometastases along the edges of the tumor that are too small to be detected, but if not removed, could cause a relapse. In such circumstances, a surgeon may opt to debride a portion of the surrounding healthy tissue to ensure that the tumor is completely removed. Types There is lack of high quality evidence to compare th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Fishing
Ice fishing is the practice of catching fish with lines and fish hooks or spears through an opening in the ice on a frozen body of water. Ice fishers may fish in the open or in heated enclosures, some with bunks and amenities. Shelters Longer fishing expeditions can be mounted with simple structures. Larger, heated structures can make multiple day fishing trips possible. A structure with various local names, but often called an ice shanty, ice shack, fish house, shack, icehouse, bobhouse, or ice hut, is sometimes used. These are dragged or towed onto the lake using a vehicle such as a snowmobile, ATV or truck. The two most commonly used types are portable and permanent. The portable houses are often made of a heavy material that is usually watertight. The two most common types of portable houses are those with a shelter that flips behind the user when not needed, or pop up shelters with a door as the only way out. The permanent shelters are made of wood or metal and usually ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Fishing Bait
Fishing bait is any substance used to attract and catch fish, e.g. on a fishing hook. Bait items are both selected from and placed within the environment to achieve enhanced prey capture success. Traditionally, fishing baits are natural fish food such as night-crawlers, insects, worms, and smaller bait fish that have been used for catching fish. Fishermen have also begun using processed food, plastic baits and more recently, bionic lures to attract fish. Despite the importance of fish's attraction to bait, the way fish react to different baits is quite poorly understood. The various techniques and bait that a fisher may choose is dictated mainly by the target species and by its habitat. Bait can be separated into two main categories: artificial baits and natural baits. The alternative of artificial and live baits frequently demonstrate similar efficiency. The overall bait type and size will affect the efficiency and results of catches when fishing. With these two common w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
