Blood Donation Restrictions On Men Who Have Sex With Men
Many countries have laws, regulations, or recommendations that effectively prohibit donations of blood or tissue for organ and corneal transplants from men who have sex with men (MSM), a classification of males who engage or have engaged in sex with other males, irrespective of their sexual activities with same-sex partners and of whether they identify themselves as bisexual or gay. Temporary restrictions are sometimes called "deferrals", since blood donors who are found ineligible may be found eligible at a later date. However, many deferrals are indefinite meaning that donation are not accepted at any point in the future, constituting a de facto ban. Even men who have monogamous relations with their same-sex partner are found ineligible. Restrictions vary from country to country, and in some countries practice of protected sex or periods of abstinence are not considered. The restrictions affect these men and, in some cases, any female sex partners. They do not otherwise affe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Men Who Have Sex With Men
Men who have sex with men (MSM) are male persons who engage in sexual activity with members of the same sex. The term was created in the 1990s by epidemiology, epidemiologists to study the spread of disease among all men who have sex with men, regardless of sexual identity, to include, for example, Male prostitution, male prostitutes. The term is often used in medical literature and social research to describe such men as a group for research studies. It does not describe any specific sexual activity, and which activities are covered by the term depends on context. As a constructed behavioral category The term ''men who have sex with men'' had been in use in public health discussions, especially in the context of HIV/AIDS, since 1990 or earlier, but the coining of the initialism by Michael Glick, Glick ''et al.'' in 1994 "signaled the crystallization of a new concept." This behavioral concept comes from two distinct academic perspectives. First, it was pursued by epidemiologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Donation
A blood donation occurs when a person voluntarily has blood drawn and used for blood transfusion, transfusions and/or made into biopharmaceutical medications by a process called Blood fractionation, fractionation (separation of whole blood components). Donation may be of whole blood, or of specific components directly (apheresis). Blood banks often participate in the collection process as well as the procedures that follow it. Today in the developed world, most blood donors are unpaid volunteers who donate blood for a community supply. In some countries, established supplies are limited and donors usually give blood when family or friends need a transfusion (directed donation). Many donors donate for several reasons, such as a form of charity, general awareness regarding the demand for blood, increased confidence in oneself, helping a personal friend or relative, and social pressure. Despite the many reasons that people donate, not enough potential donors actively donate. Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blood Plasma
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. It is the intravascular part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume), and contains important dissolved proteins (6–8%; e.g., serum albumins, globulins, and fibrinogen), glucose, clotting factors, electrolytes (, , , , , etc.), hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood-related disorders. Blood plasma is separated from the blood by spinning a vessel of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The blood plasma is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PrEP
PowerPC Reference Platform (PReP) was a standard system architecture for PowerPC-based computer systems (as well as a reference implementation) developed at the same time as the PowerPC processor architecture. Published by IBM in 1994, it allowed hardware vendors to build a machine that could run various operating systems, including Windows NT, OS/2, Solaris, Taligent and AIX. One of the stated goals of the PReP specification was to leverage standard PC hardware. Apple, wishing to seamlessly transition its Macintosh computers to PowerPC, found this to be particularly problematic. As it appeared no one was particularly happy with PReP, a new standard, the Common Hardware Reference Platform (CHRP), was developed and published in late 1995, incorporating the elements of both PReP and the Power Macintosh architecture. Key to CHRP was the requirement for Open Firmware (also required in PReP-compliant systems delivered after June 1, 1995), which gave vendors greatly improved support ...

Blood Transfusion
Blood transfusion is the process of transferring blood products into a person's circulation intravenously. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, white blood cells, plasma, clotting factors and platelets. Red blood cells (RBC) contain hemoglobin, and supply the cells of the body with oxygen. White blood cells are not commonly used during transfusion, but they are part of the immune system, and also fight infections. Plasma is the "yellowish" liquid part of blood, which acts as a buffer, and contains proteins and important substances needed for the body's overall health. Platelets are involved in blood clotting, preventing the body from bleeding. Before these components were known, doctors believed that blood was homogeneous. Because of this scientific misunderstanding, many patients died b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
