  2. Montreal Cognitive Assessment - Wikipedia

    en.wikipedia.org/wiki/Montreal_Cognitive_Assessment

    The Montreal Cognitive Assessment (MoCA) is a widely used screening assessment for detecting cognitive impairment. [1] It was created in 1996 by Ziad Nasreddine in Montreal , Quebec . It was validated in the setting of mild cognitive impairment (MCI), and has subsequently been adopted in numerous other clinical settings.

    4,4′-Methylenebis(2-chloroaniline) (also known as MOCA, MBOCA, and bisamine) is a substance used as a curing agent in polyurethane production. [3] MOCA is an aromatic amine which is structurally similar to benzidine , a known human bladder carcinogen.

  4. Rotating biological contactor - Wikipedia

    en.wikipedia.org/wiki/Rotating_biological_contactor

    In the 1980s problems were encountered in the USA prompting the Environmental Agency to commission a number of reports. These reports identified a number of issues and criticized the RBC process. One author suggested that since manufacturers were aware of the problem, the problems would be resolved and suggested that design engineers should ...

  5. Valvular heart disease - Wikipedia

    en.wikipedia.org/wiki/Valvular_heart_disease

    Valve failure or dysfunction can result in diminished heart functionality, though the particular consequences are dependent on the type and severity of valvular disease. Treatment of damaged valves may involve medication alone, but often involves surgical valve repair or valve replacement. [citation needed]

  6. Decellularization of porcine heart valve - Wikipedia

    en.wikipedia.org/wiki/Decellularization_of...

    Conventional mechanical valves used for replacement require anti-coagulation therapy which decreases quality of life. [4] Xenogeneic biological values require glutaraldehyde treatment to decrease the immune response to the foreign valve. [12] Still these valves eventually calcify and durability of the valve is decreased.

  7. Mitral stenosis - Wikipedia

    Treatment is not necessary in asymptomatic patients. [3] The treatment options for mitral stenosis include mitral valve replacement by surgery, and percutaneous mitral valvuloplasty by balloon catheter. [15] The indication for invasive treatment with either a mitral valve replacement or valvuloplasty is NYHA functional class III or IV symptoms.

  8. List of valves - Wikipedia

    en.wikipedia.org/wiki/List_of_valves

    Valves can be categorized into the following types, based on their operating mechanism: Ball valve, for on–off control without pressure drop. Ideal for quick shut-off, since a 90° turn completely shuts off, compared to multiple 360° turns for other manual valves; Butterfly valve, for on–off flow control in large diameter pipes

    Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
