Contact lens case contamination severity depends on species, genera and strains of micro-organisms. Different microbes have different pathogenicity at which level microbes become significant contaminant. Willcox et al5 classified isolated micro-organisms from storage cases based on their pathogenicity and assessed the level at which the microbes became contaminant. The strength of bacterial adhesion to contact lens and cases vary between different genera & species of micro-organisms and cell surface appendages. For tight adhesion sometimes pili and flagella of micro-organisms can participate. But non-piliated P. aeruginosa also can adhere with the contact lens surfaces. The adhesion of P.aeruginosa is very fast and can take as little as one

...Harvard Business School 9-596-087 Rev. February 1, 1999 Vistakon: 1 Day Acuvue Disposable Contact Lenses “Well Gary, what do you think?,” asked Bernard Walsh former CEO of Vistakon and current Company group chairman of Vistakon’s parent company Johnson & Johnson (J&J). Bernie Walsh had been president of Vistakon from 1987 to 1993. During his tenure, Vistakon had grown from a specialty manufacturer with $20 million in annual sales to a market leader in the contact lens industry with over $250 million in annual sales. Gary Kunkle had succeeded Walsh in 1993 and the two were meeting in early 1995 to review the performance of 1 Day Acuvue contact lenses in the western regional rollout. The world’s first daily disposable contact lens, 1 Day Acuvue was designed to be worn for one day and then discarded. A national launch decision needed to be made, but based on the test market and the western regional results, there were lingering concerns regarding product positioning, pricing, promotion, advertising and trade support. Vistakon was an autonomous and highly entrepreneurial division in J&J’s renowned decentralized organization, and Gary Kunkle knew the decision was his to make. However, he also knew that J&J expected product excellence and market success. As Kunkle considered his options, he recalled a remark made by Walsh, We need to be careful that we don’t allow our past success to undermine our future growth. Big companies tend to be too cautious. Now that...

They all suffered the loss caused by pecking order and cannibalism, and now most of them adopt the method of debeaking to reduce the impact of peck order, however, debeaking has some defects itself, and no matter what choice farmers make, they would concern following aspects before making the decision: whether the product or service is cost effective; the trauma that would bring to chickens, since traditional depeaking method would...

...marketing plan for ODI’s new and only product—a contact lens for chickens.1 While contact lenses serve mainly to improve human eyesight, the lens developed by ODI was made to partially blind the chickens. Garrison explained: Like so many other great discoveries, our product concept was discovered quite by accident. In 1962 a chicken farmer in Arizona had a flock of chickens that developed a severe cataract problem. When he became aware of the problem, he separated the afflicted birds from the rest of the flock and subsequently observed that the afflicted birds seemed to eat less and were much easier to handle. So dramatic was the difference that a poultry medical detailman visiting the farm, rather than being asked for a cure, was asked if there was any way to similarly afflict the rest of the flock. It has not proved possible chemically or genetically to duplicate the reduced vision of the chickens, resulting from the cataracts, but a chicken wearing the ODI lenses has its vision reduced enough to obtain the good behavior the Arizona farmer observed. This behavior has important economic implications for the chicken farmer. By the end of 1974 the ODI lens had been tested on a number of farms in California and Oregon with satisfactory results, and Garrison was convinced that “the time has come to stop worrying about the product and get this show off the ground.” While his timetable was tentative, he hoped that the ODI lens could be introduced in at least one region during...

...protrudes outwards or indents inwards * crowded teeth Scoliosis Marfan syndrome can cause the spine to become abnormally curved to the sides. This is known as scoliosis. Curvature of the spine can cause long-term backache. In severe cases, it can also make breathing difficult or the spine may press against the heart and lungs. Spondylolisthesis Spondylolisthesis occurs when one vertebra (the small bones that make up your spine) slips forward over another vertebra. This usually occurs at the bottom end of the spine, and can cause back pain and stiffness. Anyone can develop spondylolisthesis, but it more commonly affects people with Marfan syndrome. Dural ectasia The dura is the membrane (thin layer of cells) that lines your brain and spinal cord. Dural ectasia is a condition that occurs when the dura becomes weakened and expands outwards. People with Marfan syndrome are at particular risk of developing dural ectasia. As the membrane expands it can press on the vertebrae in your lower back, which can cause: * backache * headache  * numbness or pain in your legs Eyes Many people with Marfan syndrome have some type of vision problem. Lens dislocation affects half of all people with the syndrome. This is where the eye's lens (the transparent structure in the middle of your eye) falls into an abnormal position. Other...

The anterior chamber was quiet with no cells or flares rules out inflammation in the anterior chamber, which eliminates the risks of posterior synechiae. The IOPs were asymmetric, slightly lower OS than OD but still within the normal limit. A significant lowered pressure in the injured eye may indicate a penetrated wound. Dilated examination showed only commotio retinae OS with no retinal breaks or tears. The patient was diagnosed with corneal abrasion and a prophylactic antibiotic was initiated to lower the chance of infections. No contact lens patching was necessary due to the size of the corneal defect and the absence of pain. The patient was monitored for the healing of the cornea and resolution of commotio...

Visual Perception Deficit: Cataract and Glaucoma

...Liceo de Cagayn university – graduate studies | Visual Perception Deficits | Cataract & Glaucoma | Submitted by: | Nadine Angelica C. Gadia – Casiño, RN | March 18, 2012Submitted to:Ms. Delia V. Realista, RN, MANProfessor | | I. Intoduction Cataract Cataracts are common and significant cause of visual defects all over the world. A cataract is an opacification or clouding of the lens of the eye. Cataracts develop because of the alteration of transport of nutrients and metabolism in the lens. This interferes with light transmission to the retina therefore affecting the ability to perceive images clearly. All cells of the lens formed in the lifetime is retained therefore prevalence of cataracts increase rapidly with aging. WHO estimates that cataracts account for 48% of reversible blindness worldwide, which translates to about 18 million people. Cataracts affect slightly more women than men. The Beaver Dam Eye Study in the US found that 23.5% of women and 14.3% of men had a visually significant cataract by the age of 65 years. Although cataracts can be surgically removed, in many countries surgical services are inadequate, and cataract remains the leading cause of blindness. Age is the greatest risk factor in the occurrence of cataracts. Cataract, though with unclear links, may be acquired through heredity and genetics (e.g., Wilson's disease, galactosaemia, myotonic dystrophy). Early formation of cataracts is associated with the following risk factors: ...

...1 1 Nature of the interface Biosensor, in essence, is a device that detects and measures electric impulses in biological elements such as skin, muscle or brains. Biosensors can also be used to detect certain biological analytes or in other words, components, from chemical substances. This could be the concentration of a distinct conductive element in the blood flow of a person for example or a toxin in a food product. The use of biosensors provides a multitude of different inputs for a user interface. Biosensors themselves are rather inadequate in order to be used as the sole way to control a user interface. Instead they can be used to enhance the user experience and widen the range of input methods used in an interface. For example the use of biosensors enables a system to respond to the user’s heartbeat rate and muscle tension or to identify the position and movement of body parts such as fingers. Currently, existing biosensors measure physiological activity, muscle electrical activity, brain electrical activity, and eye movement among other things. Extracting accurate physiological data from biosensors is often a complex task. In particular, extracting data from different typologies of biosensors will require architecture of great flexibility and the possibility to connect them to different external monitoring devices. Biosensors are key components in both physiological and psychophysiological computing. Psychophysiological computing can be considered to be the same as...

Laboratory Notes from Book

...General Botany I involves the study of minute structures which are invisible of poorly seen with the naked eye. This requires the use of the microscope, the primary purpose of which is to magnify or greatly enlarge the image of the objects or organisms so their detailed structures may be studied. For our purposes, the monocular compound microscope will be used. It is an optical instrument with two lens systems:  the objectives and the eyepiece or ocular. It can magnify an image up to several hundred times the actual size of an object. For effective use and proper care of the microscope, one must become familiar with its construction, parts and uses. There are three sets of parts: namely, the mechanical, illuminating, and magnifying parts.   A. Mechanical Parts   1.      Base- the U-shaped structure on which the microscope firmly rests in the place. 2.      Pillar- the post of vertical extension of the base and to which the arm is attached. 3.      Arm- the curve structure that connects the base and the body tube which serves as the handle of the microscope and at the same time supports the optical instrument. 4.      Inclination joint- a movable hinge that attaches the frame of the microscope to the base and is used for tilting the microscope whenever necessary. 5.      Stage- the platform upon which the slide containing the specimen to be studied is placed and is provided with a central opening allowing light to pass from below into the object of study. 6.      Substage- found...
