Trephining
Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb ''trepan'' derives from Old French from -4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... from Medieval Latin from Ancient Greek">Greek , literally "borer, auger"), is a surgical intervention in which a hole is drilled or scraped into the human skull. The intentional perforation of the cranium exposes the ''dura mater'' to treat health problems related to intracranial diseases or release pressured blood buildup from an injury. It may also refer to any " burr" hole created through other body surfaces, including nail beds. A trephine is an instrument used for cutting out a round piece of skull bone to relieve pressure beneath a surface. Trepanning was sometimes performed on people who were behaving in a manner that was considered abnormal. In some ancient societies it was believed this released the evil sp ...

Subungual Hematoma
A subungual hematoma is a collection of blood ( hematoma) underneath a toenail or fingernail. It can be extremely painful for an injury of its size, although otherwise it is not a serious medical condition. Nature A laceration of the nail bed causes bleeding into the constricted area underneath the hard nail plate. The blood pools under the nail, giving a reddish, brownish, blueish, or grey/blackish discoloration. The blood puts pressure to the nailbed causing pain which can be throbbing in quality and disappears when the pressure on the nail bed is relieved. Subungual hematomas typically heal without incident, though infection may occur. The pressure of the blood blister may cause separation of nail plate from the nail bed ( onycholysis), but the nail should not be pulled off, as this can cause scarring of the nailbed and deformed nails. Nail discolouration may last some months. The nail plate may also become thicker and more brittle as a result of the injury ( onychoch ...

Stoma (medicine)
In anatomy, a stoma (: stomata or stomas) is any opening in the body. For example, a mouth, a nose, and an anus are natural stomata. Any hollow organ can be manipulated into an artificial stoma as necessary. This includes the esophagus, stomach, duodenum, ileum, colon, pleural cavity, ureters, urinary bladder, and renal pelvis. Such a stoma may be permanent or temporary. Surgical procedures that involve the creation of an artificial stoma have names that typically end with the suffix "-ostomy", and the same names are also often used to refer to the stoma thus created. For example, the word " colostomy" often refers either to an artificial anus or the procedure that creates one. Accordingly, it is not unusual for a stoma to be called an ostomy (plural ostomies), as is the norm in wound, ostomy, and continence nursing. Gastrointestinal stomata Stomata are created in particular in surgical procedures involving the gastrointestinal tract (GIT) or gastrointestinal system (GIS) ...

Pre-Columbian
In the history of the Americas, the pre-Columbian era, also known as the pre-contact era, or as the pre-Cabraline era specifically in Brazil, spans from the initial peopling of the Americas in the Upper Paleolithic to the onset of European colonization of the Americas, European colonization, which began with Christopher Columbus's voyage in 1492. This era encompasses the history of Indigenous peoples of the Americas, Indigenous cultures prior to significant European influence, which in some cases did not occur until decades or even centuries after Columbus's arrival. During the pre-Columbian era, many civilizations developed permanent settlements, cities, agricultural practices, civic and monumental architecture, major Earthworks (archaeology), earthworks, and Complex society, complex societal hierarchies. Some of these civilizations had declined by the time of the establishment of the first permanent European colonies, around the late 16th to early 17th centuries, and are know ...

Postclassical
In Human history, world history, post-classical history refers to the period from about 500 CE to 1500 CE, roughly corresponding to the European Middle Ages. The period is characterized by the expansion of civilizations geographically and the development of trade networks between civilizations.The Post‐Classical Era by Joel Hermansen This period is also called the medieval era, post-antiquity era, post-ancient era, pre-modernity era, or pre-modern era. In Asia, the spread of Islam created a series of caliphates and inaugurated the Islamic Golden Age, leading to advances in science in the medieval Islamic world and trade among the Asian, African, and European continents. East Asia experienced the full establishment of the power of History of China#Imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Testing
Animal testing, also known as animal experimentation, animal research, and ''in vivo'' testing, is the use of animals, as model organisms, in experiments that seek answers to scientific and medical questions. This approach can be contrasted with field studies in which animals are observed in their natural environments or habitats. Experimental research with animals is usually conducted in universities, medical schools, pharmaceutical companies, defense establishments, and commercial facilities that provide animal-testing services to the industry. The focus of animal testing varies on a continuum from Basic research, pure research, focusing on developing fundamental knowledge of an organism, to applied research, which may focus on answering some questions of great practical importance, such as finding a cure for a disease. Examples of applied research include testing disease treatments, breeding, defense research, and Toxicology testing, toxicology, including Testing cosmetics ...

Veterinary Surgery
Veterinary surgery is surgery performed on non-human animals by veterinarians, whereby the procedures fall into three broad categories: orthopaedics (bones, joints, muscles), soft tissue surgery (skin, body cavities, cardiovascular system, GI/urogenital/respiratory tracts), and neurosurgery. Advanced surgical procedures such as joint replacement (total hip, knee and elbow replacement), fracture repair, stabilization of cranial cruciate ligament deficiency, oncologic (cancer) surgery, herniated disc treatment, complicated gastrointestinal or urogenital procedures, kidney transplant, skin grafts, complicated wound management, and minimally invasive procedures ( arthroscopy, laparoscopy, thoracoscopy) are performed by veterinary surgeons (as registered in their jurisdiction). Most general practice veterinarians perform routine surgeries such as neuters and minor mass excisions; some also perform additional procedures. The goal of veterinary surgery may be quite different in pets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Americas
The Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America.'' Webster's New World College Dictionary'', 2010 by Wiley Publishing, Inc., Cleveland, Ohio. When viewed as a single continent, the Americas or America is the 2nd largest continent by area after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon, St. Lawrence River–Great Lakes, Mississippi, and La Plata basins. Since the Americas extend from north to south, the climate and ecology vary widely, from the arctic tundra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Archaeological
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. The discipline involves Survey (archaeology), surveying, Archaeological excavation, excavation, and eventually Post excavation, analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. A ...
