RhD Antigen
The Rh blood group system is a human blood group system. It contains proteins on the surface of red blood cells. After the ABO blood group system, it is most likely to be involved in transfusion reactions. The Rh blood group system consisted of 49 defined blood group antigens in 2005. there are over 50 antigens, of which the five antigens D, C, c, E, and e are among the most prominent. There is no d antigen. Rh(D) status of an individual is normally described with a ''positive'' (+) or ''negative'' (−) suffix after the ABO type (e.g., someone who is A+ has the A antigen and Rh(D) antigen, whereas someone who is A− has the A antigen but lacks the Rh(D) antigen). The terms ''Rh factor'', ''Rh positive'', and ''Rh negative'' refer to the Rh(D) antigen only. Antibodies to Rh antigens can be involved in hemolytic transfusion reactions and antibodies to the Rh(D) and Rh antigens confer significant risk of hemolytic disease of the newborn.

Rhesus Monkey
The rhesus macaque (''Macaca mulatta''), colloquially rhesus monkey, is a species of Old World monkey. There are between six and nine recognised subspecies split between two groups, the Chinese-derived and the Indian-derived. Generally brown or grey in colour, it is in length with a tail and weighs . It is native to South, Central, and Southeast Asia and has the widest geographic range of all non-human primates, occupying a great diversity of altitudes and habitats. The rhesus macaque is diurnal, arboreal, and terrestrial. It is mostly herbivorous, feeding mainly on fruit, but also eating seeds, roots, buds, bark, and cereals. Rhesus macaques living in cities also eat human food and trash. They are gregarious, with troops comprising 20–200 individuals. The social groups are matrilineal. Individuals communicate with a variety of facial expressions, vocalisations, body postures, and gestures. As a result of the rhesus macaque's relatively easy upkeep, wide availability, and ...

Judea
Judea or Judaea (; ; , ; ) is a mountainous region of the Levant. Traditionally dominated by the city of Jerusalem, it is now part of Palestine and Israel. The name's usage is historic, having been used in antiquity and still into the present day; it originates from Yehudah, a Hebrew name. Yehudah was a son of Jacob, who was later given the name "Israel" and whose sons collectively headed the Twelve Tribes of Israel. Yehudah's progeny among the Israelites formed the Tribe of Judah, with whom the Kingdom of Judah is associated. Related nomenclature continued to be used under the rule of the Babylonians (the Yehud province), the Persians (the Yehud province), the Greeks (the Hasmonean Kingdom), and the Romans (the Herodian Kingdom and the Judaea province). Under the Hasmoneans, the Herodians, and the Romans, the term was applied to an area larger than Judea of earlier periods. In the aftermath of the Bar Kokhba revolt (c. 132–136 CE), the Roman province of Judaea w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exsanguination
Exsanguination is the loss of blood from the circulatory system of a vertebrate, usually leading to death. The word comes from the Latin 'sanguis', meaning blood, and the prefix 'ex-', meaning 'out of'. Exsanguination has long been used as a method of animal slaughter. Humane slaughter must ensure the animal is rendered insensible to pain, whether through a captive bolt or other process, prior to the bloodletting. Depending upon the health of the individual, a person usually dies from losing half to two-thirds of their blood; a loss of roughly one-third of the blood volume is Critical condition, considered very serious. Even a single deep cut can warrant Surgical suture, suturing and Inpatient care, hospitalization, especially if Trauma (medicine), trauma, a vein or artery, or another comorbidity is involved. In the past, bloodletting was a common medical procedure or therapy, now rarely used in medicine. Slaughtering of animals Exsanguination is used as a Animal slaughter, s ...

Alloimmunization
Alloimmunity (sometimes called isoimmunity) is an immune response to nonself antigens from members of the same species, which are called alloantigens or isoantigens. Two major types of alloantigens are blood group antigens and histocompatibility antigens. In alloimmunity, the body creates antibodies (called alloantibodies) against the alloantigens, attacking transfused blood, allotransplanted tissue, and even the fetus in some cases. Alloimmune (isoimmune) response results in graft rejection, which is manifested as deterioration or complete loss of graft function. In contrast, autoimmunity is an immune response to the self's own antigens. (The ''allo-'' prefix means "other", whereas the ''auto-'' prefix means "self".) Alloimmunization (isoimmunization) is the process of becoming alloimmune, that is, developing the relevant antibodies for the first time. Alloimmunity is caused by the difference between products of highly polymorphic genes, primarily genes of the major histocompa ...

Immunoglobulin G
Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. IgG molecules are created and released by plasma B cells. Each IgG antibody has two paratopes. Function Antibodies are major components of humoral immunity. IgG is the main type of antibody found in blood and extracellular fluid, allowing it to control infection of body tissues. By binding many kinds of pathogens such as viruses, bacteria, and fungi, IgG protects the body from infection. It does this through several mechanisms: * IgG-mediated binding of pathogens causes their immobilization and binding together via agglutination; IgG coating of pathogen surfaces (known as opsonization) allows their recognition and ingestion by phagocytic immune cells leading to the elimination of the pathogen itself; * IgG activates the classical pathway of the complement system, a cascade of immune protein product ...

Levant
The Levant ( ) is the subregion that borders the Eastern Mediterranean, Eastern Mediterranean sea to the west, and forms the core of West Asia and the political term, Middle East, ''Middle East''. In its narrowest sense, which is in use today in archaeology and other cultural contexts, it is equivalent to Cyprus and a stretch of land bordering the Mediterranean Sea in Western AsiaGasiorowski, Mark (2016). ''The Government and Politics of the Middle East and North Africa''. p. 5: "... today the term ''Levantine'' can describe shared cultural products, such as Levantine cuisine or Levantine archaeology". .Steiner & Killebrew, p9: "The general limits ..., as defined here, begin at the Plain of 'Amuq in the north and extend south until the Wâdī al-Arish, along the northern coast of Sinai. ...

Palestinians
Palestinians () are an Arab ethnonational group native to the Levantine region of Palestine. *: "Palestine was part of the first wave of conquest following Muhammad's death in 632 CE; Jerusalem fell to the Caliph Umar in 638. The indigenous population, descended from Jews, other Semitic groups, and non-Semitic groups such as the Philistines, had been mostly Christianized. Over succeeding centuries it was Islamicized, and Arabic replaced Aramaic (a Semitic tongue closely related to Hebrew) as the dominant language" * : "Palestinians are the descendants of all the indigenous peoples who lived in Palestine over the centuries; since the seventh century, they have been predominantly Muslim in religion and almost completely Arab in language and culture." * : "Furthermore, Zionism itself was also defined by its opposition to the indigenous Palestinian inhabitants of the region.

North Africa
North Africa (sometimes Northern Africa) is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region. However, it is sometimes defined as stretching from the Atlantic shores of the Western Sahara in the west, to Egypt and Sudan's Red Sea coast in the east. The most common definition for the region's boundaries includes Algeria, Egypt, Libya, Morocco, Tunisia, and Western Sahara, the territory territorial dispute, disputed between Morocco and the list of states with limited recognition, partially recognized Sahrawi Arab Democratic Republic. The United Nations’ definition includes all these countries as well as Sudan. The African Union defines the region similarly, only differing from the UN in excluding the Sudan and including Mauritania. The Sahel, south of the Sahara, Sahara Desert, can be considered as the southern boundary of North Africa. North Africa includes the Spanish cities of Ceuta and Melilla, and the ...

Afroasiatic Languages
The Afroasiatic languages (also known as Afro-Asiatic, Afrasian, Hamito-Semitic, or Semito-Hamitic) are a language family (or "phylum") of about 400 languages spoken predominantly in West Asia, North Africa, the Horn of Africa, and parts of the Sahara and Sahel. Over 500 million people are native speakers of an Afroasiatic language, constituting the fourth-largest language family after Indo-European, Sino-Tibetan, and Niger–Congo. Most linguists divide the family into six branches: Berber (Amazigh), Chadic, Cushitic, Egyptian, Omotic, and Semitic. The vast majority of Afroasiatic languages are considered indigenous to the African continent, including all those not belonging to the Semitic branch (which originated in West Asia). The five most spoken languages are; Arabic (of all varieties) which is by far the most widely spoken within the family, with around 411 million native speakers concentrated primarily in West Asia and North Africa, the Chadic Hausa language w ...

Jews
Jews (, , ), or the Jewish people, are an ethnoreligious group and nation, originating from the Israelites of History of ancient Israel and Judah, ancient Israel and Judah. They also traditionally adhere to Judaism. Jewish ethnicity, religion, and community are highly interrelated, as Judaism is their ethnic religion, though it is not practiced by all ethnic Jews. Despite this, religious Jews regard Gerim, converts to Judaism as members of the Jewish nation, pursuant to the Conversion to Judaism, long-standing conversion process. The Israelites emerged from the pre-existing Canaanite peoples to establish Kingdom of Israel (Samaria), Israel and Kingdom of Judah, Judah in the Southern Levant during the Iron Age.John Day (Old Testament scholar), John Day (2005), ''In Search of Pre-Exilic Israel'', Bloomsbury Publishing, pp. 47.5 [48] 'In this sense, the emergence of ancient Israel is viewed not as the cause of the demise of Canaanite culture but as its upshot'.

Ashkenazi
Ashkenazi Jews ( ; also known as Ashkenazic Jews or Ashkenazim) form a distinct subgroup of the Jewish diaspora, that Ethnogenesis, emerged in the Holy Roman Empire around the end of the first millennium Common era, CE. They traditionally speak Yiddish, a language that originated in the 9th century, and largely migrated towards Northern Europe#UN geoscheme classification, northern and eastern Europe during the late Middle Ages due to Antisemitism in Europe, persecution. Hebrew was primarily used as a Literary language, literary and sacred language until its 20th-century Revival of the Hebrew language, revival as a common language in Israel. Ashkenazim adapted their traditions to Europe and underwent a transformation in their interpretation of Judaism. In the late 18th and 19th centuries, Jews who remained in or returned to historical German lands experienced a cultural reorientation.
