Piercing Migration
Piercing migration is a body piercing's movement from its initial location. Migration may be unnoticed, or painful with progression. It may be slight and brief, or continue until exiting the skin. Potential causes and effects of migration Migration varies widely. The most common case is heavy, small gauge earrings moving down until exiting the earlobe after most of a lifetime. It is dubbed the "cheese-cutter effect", because of its similarity to cutting cheese using a fine wire. Contemporary body and ear piercing jewelry mitigates the effect by increasing the weight to gauge ratio. However, migration remains possible, especially with heavy jewelry, even of large gauge. Another migration cause, though rare, is play or movement affecting the pierced or implanted area, either by causing a wound, or merely stretching the fistula in one direction, thus allowing tissue growth in the void behind. The latter can affect tongue piercings, for example, but neither normally induces exit fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nipple Ring Migration
The nipple is a raised region of tissue on the surface of the breast from which, in lactating females, milk from the mammary gland leaves the body through the lactiferous ducts to nurse an infant. The milk can flow through the nipple passively, or it can be ejected by smooth muscle contractions that occur along with the ductal system. The nipple is surrounded by the areola, which is often a darker colour than the surrounding skin. Male mammals also have nipples but without the same level of function or prominence. A nipple is often called a ''teat'' when referring to non-humans. "Nipple" or "teat" can also be used to describe the flexible mouthpiece of a baby bottle. In humans, the nipples of both males and females can be sexually stimulated as part of sexual arousal. In many cultures, female nipples are sexualized, or regarded as sex objects and evaluated in terms of their physical characteristics and sex appeal. Etymology The word "nipple" most likely originates as a diminut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navel Piercing
A navel piercing, also referred to as a belly button piercing, is a type of body piercing that penetrates the skin of the navel. It is most commonly located on the upper fold of skin but can also be placed underneath or around the edges of the navel. Healing usually takes around 6–12 months but can vary from person-to-person due to differences in physiology. History The history of navel piercing has been misrepresented as many of the myths promulgated by Doug Malloy in the pamphlet ''Body & Genital Piercing in Brief'' continue to be reprinted. For instance, according to Malloy's colleague Jim Ward, Malloy alleged that navel piercing was popular among ancient Egyptian aristocrats and was depicted in Egyptian statuary, an allegation that is widely repeated. However, other sources deny that the historical record supports the allegation."Navel piercing. Unlike the other body piercings, this one has not been recorded in history."

Earrings
Earrings are jewelry that can be worn on one's ears. Earrings are commonly worn in a piercing in the earlobe or another external part of the ear, or by some other means, such as stickers or clip-ons. Earrings have been worn across multiple civilizations and historic periods, often carrying a cultural significance. Locations for piercings other than the earlobe include the rook, tragus, and across the helix (see image in the infobox). The simple term "ear piercing" usually refers to an earlobe piercing, whereas piercings in the upper part of the external ear are often referred to as "cartilage piercings". Cartilage piercings are more complex to perform than earlobe piercings and take longer to heal. Earring components may be made of any number of materials, including metal, plastic, glass, precious stone, beads, wood, bone, and other materials. Designs range from small hoops and studs to large plates and dangling items. The size is ultimately limited by the physical capacity ...

Nape Piercing
A nape piercing is a piercing through the surface of the nape (back part) of the neck. Nape piercings are a type of surface piercing. They carry a high rate of rejection and migration, ''A Statistical Look at Surface Bars'' unless they are properly measured and placed. They may reject if they are not pierced properly, as they are in a part of the body that moves constantly and are easy to irritate, catching on clothing or other objects. Being surface piercings, nape piercings require special jewelry to minimize the risk of piercing migration and rejection. Both s and |
Christina Piercing
A Christina piercing, also known as a Venus piercing, is a female genital piercing. It is located where the outer labia meet, below the pubic mound. The Christina piercing is anatomy dependent; it has a high rejection rate, and is not possible for all women due to anatomical variation. If the flesh above the clitoris where the outer labia meet is fleshy enough to pinch, a Christina piercing may be successful. If the flesh in this area is too tight to pinch, a Christina piercing is contraindicated. The piercing does not facilitate sexual stimulation and can be found uncomfortable when pressure is applied. It is usually pierced with either a custom-made curved barbell or surface bar to reduce the risk of rejection. The Christina piercing is of contemporary origin. The first known Christina piercing was performed in the 1990s. As is common practice in the piercing industry, it was named after the first recipient of the piercing, a woman named Christina. It is also occasionally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infection
An infection is the invasion of tissue (biology), tissues by pathogens, their multiplication, and the reaction of host (biology), host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an Disease#Terminology, illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently pathogenic bacteria, bacteria and viruses. Hosts can fight infections using their immune systems. Mammalian hosts react to infections with an Innate immune system, innate response, often involving inflammation, followed by an Adaptive immune system, adaptive response. Treatment for infections depends on the type of pathogen involved. Common medications include: * Antibiotics for bacterial infections. * Antivirals for viral infections. * Antifungals for fungal infections. * Antiprotozoals for protozoan infections. * Antihelminthics for infections caused by parasi ...

Road Rash
Road rash is a colloquial term for skin injury caused by abrasion with road surfaces, often as a consequence of cycling and motorcycling accidents. It may also result from running, inline skating, roller skating, skateboarding, and longboarding accidents. The term may be applied to both a fresh injury and also to the scar tissue left by an old injury. Symptoms may include pain and heavy bleeding. Motorcyclists can reduce the risks of road rash by wearing appropriate motorcycle personal protective equipment such as a full face helmet, protective clothing, gloves, dusters and boots. Similarly, inline skaters can reduce their chance of such abrasion injuries by wearing protective knee and elbow pads. Road rash is often termed 'gravel rash' in the United Kingdom. That term is old, appearing (with hyphen) as 'gravel-rash' in Rudyard Kipling Joseph Rudyard Kipling ( ; 30 December 1865 – 18 January 1936)''The Times'', (London) 18 January 1936, p. 12. was an English jo ...

Splinter
A splinter (also known as a sliver) is a fragment of a larger object, or a foreign body that penetrates or is purposely injected into a body. The foreign body must be lodged inside tissue to be considered a splinter. Splinters may cause initial pain through ripping of flesh and muscle, or infection through bacteria on the foreign object. Splinters are primarily made of wood, but there are many other types, for example, other common types of splinters are, hair, glass, plastic, metal, and spines of animals. As with any wound that breaks the skin, splinters can lead to infection, which if left untreated could develop into more serious complications. If a splinter is in the body for more than 2–3 days, or if the wound shows signs of inflammation or tenderness (whether the splinter was removed or not), advice should be sought from a doctor. Getting a splinter Generally, a splinter causes an initial feeling of pain as the sharp object makes its initial penetration through th ...

Biological Tissue
In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. Tissues occupy a biological organizational level between cells and a complete organ. Accordingly, organs are formed by the functional grouping together of multiple tissues. The English word "tissue" derives from the French word "", the past participle of the verb tisser, "to weave". The study of tissues is known as histology or, in connection with disease, as histopathology. Xavier Bichat is considered as the "Father of Histology". Plant histology is studied in both plant anatomy and physiology. The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope. Developments in electron microscopy, immunofluorescence, and the use of frozen tissue-sections have enhanced the detail that can be observed in tissues. ...

Drainage
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley Civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Simple infrastructure such as open drains, pipes, and berms are still common. In modern times, more complex structures involving substantial earthworks and new technologies have been common as well. Geotextiles New storm water drainag ...
