Enzyme Immobilization
An immobilized enzyme is an enzyme, with restricted mobility, attached to an inert, insoluble material—such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride). This can provide increased resistance to changes in conditions such as pH or temperature. It also lets enzymes be held in place throughout the reaction, following which they are easily separated from the products and may be used again - a far more efficient process and so is widely used in industry for enzyme catalysed Enzyme catalysis, reactions. An alternative to enzyme immobilization is whole cell immobilization. Immobilized enzymes are easily to be handled, simply separated from their products, and can be reused. Enzymes are bio-catalysts which play an essential role in the enhancement of chemical reactions in cells without being persistently modified, wasted, nor resulting in the loss of equilibrium of chemical reactions. Although the characteristi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immobilization (soil Science)
Immobilization in soil science is the conversion of inorganic compounds to organic compounds by microorganisms or plants by which the compounds become inaccessible to plants. Immobilization is the opposite of mineralization. In immobilization, inorganic nutrients are taken up by soil microbes and become unavailable for plant uptake. Immobilization is therefore a biological process controlled by bacteria that consume inorganic nitrogen and form amino acids and biological macromolecules (organic forms). Immobilization and mineralization are continuous processes that occur concurrently whereby nitrogen of the decomposing system is steadily transformed from an inorganic to an organic state by immobilization and from an organic to an inorganic state by decay and mineralization. C:N Ratio Whether nitrogen is mineralized or immobilized depends on the C/N ratio of the plant residues. For example, incorporating materials high in carbon to nitrogen ratio such as saw dust and straw will sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whole Cell Immobilization
The immobilized whole cell system is an alternative to enzyme immobilization. Unlike enzyme immobilization, where the enzyme is attached to a solid support (such as calcium alginate or activated PVA or activated PEI), in immobilized whole cell systems, the target cell is immobilized. Such methods may be implemented when the enzymes required are difficult or expensive to extract, an example being intracellular This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms. It is intended as introductory material for novices; for more specific and technical definitions ... enzymes. Also, if a series of enzymes are required in the reaction; whole cell immobilization may be used for convenience. This is only done on a commercial basis when the need for the product is more justified. Multiple enzymes may be introduced into the reaction, thus eliminating the need for immobilization of multiple enzymes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bed Rest
Bed rest, also referred to as the rest-cure, is a medical treatment in which a person lies in bed for most of the time to try to cure an illness. Bed rest refers to voluntarily lying in bed as a treatment and not being confined to bed because of a health impairment which physically prevents leaving bed. The practice is still used although a 1999 systematic review found no benefits for any of the 17 conditions studied and no proven benefit for any conditions at all, beyond that imposed by symptoms. In the United States, nearly 20% of pregnant women have some degree of restricted activity prescribed despite the growing data showing it to be dangerous, causing some experts to call its use "unethical". Medical uses Extended bed rest has been proven to be a potentially harmful treatment needing more careful evaluation. Pregnancy Women who are pregnant and are experiencing early labor, vaginal bleeding, and cervix complications have been prescribed bed rest. This practice in 2013 wa ...

Splint (medicine)
A splint is defined as "a rigid or flexible device that maintains in position a displaced or movable part; also used to keep in place and protect an injured part" or as "a rigid or flexible material used to protect, immobilize, or restrict motion in a part". Splints can be used for injuries that are not severe enough to immobilize the entire injured structure of the body. For instance, a splint can be used for certain fractures, soft tissue sprains, tendon injuries, or injuries awaiting orthopedic treatment. A splint may be static, not allowing motion, or dynamic, allowing controlled motion. Splints can also be used to relieve pain in damaged joints. Splints are quick and easy to apply and do not require a plastering technique. Splints are often made out of some kind of flexible material and a firm pole-like structure for stability. They often buckle or Velcro together. Uses * By the emergency medical services or by volunteer first responders, to temporarily immobilize a fractu ...

Orthopedic Cast
An orthopedic cast, commonly referred to simply as a cast, is a form of medical treatment used to immobilize and support bones and soft tissues during the healing process after fractures, surgeries, or severe injuries. By restricting movement, casts provide stability to the affected area, enabling proper alignment and healing of bones, ligaments, and tendons. They are commonly applied to the limbs but can also be used for the trunk, neck, or other parts of the body in specific cases. Orthopedic casts come in various types and designs, tailored to the nature and severity of the injury, as well as the patient's needs. Advances in medical techniques have made casts more comfortable, effective, and versatile, allowing for both weight-bearing and non-weight-bearing options. Upper extremity casts Upper extremity casts are frequently utilized to immobilize the arm, wrist, or hand for the treatment of fractures, soft tissue injuries, or during post-surgical recovery. They offer stabil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthotics
Orthotics () is a medical specialty that focuses on the design and application of orthoses, sometimes known as braces, calipers, or splints. An is "an externally applied device used to influence the structural and functional characteristics of the neuromuscular and skeletal systems." Orthotists are medical professionals who specialize in designing orthotic devices such as braces or foot orthoses. Classification Orthotic devices are classified into four areas of the body according to the international classification system (ICS): orthotics of the lower extremities, orthotics of the upper extremities, orthotics for the trunk, and orthotics for the head. Orthoses are also classified by function: paralysis orthoses and relief orthoses. Under the International Standard terminology, orthoses are classified by an acronym describing the anatomical joints they support. Some examples include KAFO, or knee-ankle-foot orthoses, which span the knee, ankle, and foot; TLSO, or thor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muscle Immobilization
Paralysis (: paralyses; also known as plegia) is a loss of motor function in one or more muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed with some form of permanent or transient paralysis. The word "paralysis" derives from the Greek παράλυσις, meaning "disabling of the nerves" from παρά (''para'') meaning "beside, by" and λύσις (''lysis'') meaning "making loose". A paralysis accompanied by involuntary tremors is usually called " palsy". Causes Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson's disease, ALS, botulism, spina bifida, multiple sclerosis and Guillain–Barré syndrome. Incidents that can cause such damage include slip and fall accidents, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trauma Immobilization
A spinal board, is a patient handling device used primarily in pre-hospital trauma care. It is designed to provide rigid support during movement of a person with suspected spinal or limb injuries. They are most commonly used by ambulance staff, as well as lifeguards and ski patrollers. Historically, backboards were also used in an attempt to "improve the posture" of young people, especially girls. Due to lack of evidence to support long-term use, the practice of keeping people on long boards for prolonged periods of time is decreasing. Extrication uses The spinal backboard was originally designed as a device to remove people from a vehicle. After a time people were simply kept on the spine board for transport without evidence supporting this need. Medical uses A spinal board is primarily indicated for judicious use to transport people who may have had a spinal injury, usually due to the mechanism of injury, and the attending team are not able to rule out a spinal injury.

Sedentary Lifestyle
Sedentary lifestyle is a Lifestyle (social sciences), lifestyle type, in which one is physically inactive and does little or no physical movement and/or exercise. A person living a sedentary lifestyle is often sitting or lying down while engaged in an activity like socializing, Social aspects of television, watching TV, Gameplay, playing video games, reading or Problematic smartphone use, using a mobile phone or computer for much of the day. A sedentary lifestyle contributes to poor health quality, diseases as well as many preventable causes of death. Sitting time is a common measure of a sedentary lifestyle. A global review representing 47% of the global adult population found that the average person sits down for 4.7 to 6.5 hours a day with the average going up every year. The Centers for Disease Control and Prevention, CDC found that 25.3% of all American adults are physically inactive. Screen time is a term for the amount of time a person spends looking at a screen such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automobile Immobilization
An immobiliser or immobilizer is an electronic security device fitted to a motor vehicle that prevents the engine from being started unless the correct key (transponder or smart key) is present. This prevents the vehicle from being " hot wired" after entry has been achieved and thus reduces motor vehicle theft. Research shows that the uniform application of immobilisers reduced the rate of car theft by 40%. Description The electric immobiliser/alarm system was invented by St. George Evans and Edward Birkenbeuel and patented in 1919. They developed a 3x3 grid of double-contact switches on a panel mounted inside the car so when the ignition switch was activated, current from the battery (or magneto) went to the spark plugs allowing the engine to start, or immobilizing the vehicle and sounding the horn. The system settings could be changed each time the car was driven. Modern immobiliser systems are automatic, meaning the owner does not have to remember to activate it. Ear ...
