Long-term laboratory maintenance of bryozoans Bryozoan colonies were successfully maintained for periods in excess of six months using this methodology. It was found that a large number of macroinvertebrates colonised the Petri dishes, some of which including midge larvae (Diptera: Chironomidae) were observed to feed on bryozoan material. In addition, many oligochaetes including those belonging to the families Naididae Muller, 1773 and Tubificidae Muller, 1774 as identified by the key of Brinkhurst (1963) were seen to be associated with the bryozoans. Some of the other plates were seen to have dead bryozoan remnants attached to them. No characteristic signs of malacosporean infection were observed during the period of maintenance of the colonies. Ehrenberg, Monoraphidium contortum (Thuret) Komarkova-Legnerova, Actinastrum hantzschii Lagerheim, Scenedesmus dimorphus (Turpin) Kutzing and Selenastrum sp. Version 1 Three weeks after seeding the tank, it was found to be of turbid green appearance. Although successful in preventing the sedimentation of algae and protozoa, there was some difficulty with the current from the water pump leading to dislodging of some of the Petri dishes from their rack. One week following addition of the bryozoans, the tank was found to contain vast numbers of chironomid larvae. At this stage, no living bryozoan material was present and many chironomid larvae were intimately associated with the dead bryozoan remnants. Version 2 Following seeding, the 150 L tank became turbid as described above with some proliferation of macroinvertebrates noted, especially chironomid larvae. At this point the water pump was activated and bryozoan colonies placed within the smaller tank. As the return flow from the larger to smaller tank depended upon a siphon system, it was necessary to meticulously extricate any air bubbles from the tubing before activating the pump. Despite such efforts, it was found that the tubing invariably became air-locked within 2-3 days of flow. This would result in the media being unable to return from the larger to smaller the tank, leading to drainage of this tank and potential desiccation of the bryozoans. Version 3 As previously seen, the larger tank became turbid within two weeks following seeding with protozoa and algae. Few macroinvertebrates were observed within the system, with no population explosion of chironomid larvae witnessed. As this system incorporated an overflow mechanism to allow return of the fluid to the lower tank, there was no problem with air-locks in the tubing. Initially, bryozoans were Chapter 2 Page 79 successfully kept in the system, although limited growth was witnessed. The turbidity of the tank was seen to be reduced after about 30 days with subsequent demise of the bryozoan colonies being witnessed. When the system was active, the mesh under the spray bars became clogged with algae within one to two weeks.

Cohen An estimated 36 million Americans are contact lens wearers, comprising nearly 10% of the United States population. Current variations in types of contact lenses, disinfection methods, and patterns of use all add to the complexity of managing corneal infiltrates in the contact lens wearer. In addition, contact lens users are subject to problems unrelated to contact lens use, such as staphylococcal hypersensitivity marginal keratitis. History A detailed history is the first important step in managing the acutely symptomatic contact lens patient. The history should include the type of contact lens worn, the pattern of lens usage, the cleaning and disinfection regimen, as well as the type and brand of cleaning solution. Breaks in standard contact lens care, such as exposure of the lenses or case to water, should be specifically sought, as this information is rarely volunteered. Any one of these pieces of information alone will certainly not make the diagnosis, but together, along with careful clinical examination, the information will guide initial diagnosis and management. Increasing pain is consistent with active infection, whereas decreasing pain after contact lens removal favors self-limited inflammation. Type of contact lens and pattern of wear It is necessary to determine whether the patient wears disposable (single use), frequent replacement (discards after a few weeks), or conventional lenses, extended or daily-wear soft contact lenses, or rigid gas-permeable lenses. Daily disposable lenses eliminate standard contact lens hazards such as improper hygiene and storage, when used correctly. Hyper-oxygen transmissible silicone hydrogel lenses were designed to reduce corneal hypoxia, hypothesized to be a major risk factor for corneal infection. However, the relative risk of microbial keratitis with silicone hydrogels was not significantly different compared to planned replacement lenses in a studies by Dart et al. Both studies demonstrated that overnight use continues to be the main risk factor for corneal infection. Even occasional overnight wear (less than 1 day per week) was associated with increased risk. Lens usage (daily vs extended wear), not lens type, was the most important risk factor for corneal ulceration. Designed specifically for overnight wear with lens removal during waking hours, reverse geometry rigid gas-permeable contact lenses are used to alter corneal shape to temporarily reduce refractive error in orthokeratology. In a series of 123 cases, Pseudomonas accounted for 37% of all cases, and Acanthamoeba was implicated in 33% of all cases. In response, the Chinese government intervened to regulate the orthokeratology market. It has also been suggested that the refractive effect was associated with thinning of the central corneal epithelium in addition to the fitting relationship of orthokeratology lenses and that this may compromise the epithelial barrier, thereby increasing the risk of infectious keratitis. Contact lens solutions and hygeine Lens care history should include questions about solutions used and any recent changes in solutions. Delayed-type hypersensitivity and toxic reactions to thimerosal were a problem in the past. Multipurpose solutions and no-rub formulas were introduced in recent years to improve patient compliance. Further investigations did not reveal microbial contamination of either solution; however, both solutions were ultimately removed from commercial markets. A study by Chang suggests that exposure to Fusarium was likely from the sink area or shower water. Although suboptimal contact lens hygiene practices appear unlikely as the major explanation for the outbreak, one hygiene practice that was statistically significant on univariate analysis was storing lenses by reusing contact lens solution already in the lens case. Because inadequate lens care hygiene may increase the incidence of microbial keratitis, patients should be questioned about high-risk behaviors, which include topping off of old solutions in the case, infrequent replacement of the contact lens storage case, failure to wash hands before handling lenses, exposure of the lens or lens case to tap water, including swimming or showering while wearing lenses, and elimination of the digital rubbing step.

Chlorination and Washes Chlorination arteria adamkiewicz purchase 12.5 mg lopressor, as commonly used for fresh-cut salad sanitation, may not be desirable for all fresh-cut fruits. Postcutting washing and/or dipping may have negative conse quences regarding increased water activity and the washing away? of desirable? Numerous processors do not wash freshly cut fruits that have little or no browning. Calcium Salts and Antibrowning Application of aqueous solutions of calcium salts, ascorbate, citric acid, isoascorbic acid and sodium erythorbate (generally 0. Unfortunately, some treat ments that reduce enzymatic browning or improve texture can impart off-? After 10 days of storage in air at 0?C, 70% of consumers judged fresh-cut Bartlett? pear that were treated with 2% ascorbic acid, 1% calcium lactate and 0. Numerous new experimental compounds (ascorbic acid-2-phosphate and ascor bic acid-2-triphosphate, calcium propionate, cysteine, N-acetylcysteine and 4-hex ylresorcinol) are being tested for antibrowning capacities. Analyses of organic acids and the major sugars revealed that the slices treated with combined antibrowning compounds retained higher levels of malic acid and had no deterioration in sugar levels at 5 and 10?C, indicating that higher quality was maintained during storage. Antimicrobial, Edible Coating and Other Treatment Compounds Treatment of fruits and vegetables with acetaldehyde, ethanol or low O2 (which can result in production of acetaldehyde and ethanol) has resulted in? For example, in strawberry, an increase in acetaldehyde, ethanol, methyl acetate, ethyl acetate and ethyl butyrate was found after application of acetaldehyde (Pesis, 1996). Treatment of oranges with acetaldehyde resulted in induced synthesis of ethylbutyrate (Shaw et al. Treatment of tomatoes, blueberries and pears led to enhanced sensory quality, in part due to increased sugars (Paz et al. However, attempts to promote volatile and sensory attributes with vaporous acetaldehyde or alcohol in fresh-cut fruits may be quite challenging, because these compounds have a maturity and concentration-dependent effect on inhibiting or promoting ripening (Beaulieu and Saltveit, 1997; Beaulieu et al. Nevertheless, treatment of whole fruit with acetaldehyde, ethanol or low O2 may improve? Intact Fruits were Incubated in Saturated Ethanol Vapor at 23?C for 24 Hours before Slicing, or Cut Slices were Dipped in 70% Ethanol for 30 Seconds Day 0 Day 7? Whole apples were treated with ethanol vapor prior to slicing, and sliced apples received an ethanol dip. In both cases, after two weeks of storage, the ethanol-treated apples were higher in some volatiles, including several esters (Table 12. Hexanal is a natural aroma precursor in apples that is readily converted to aroma volatiles in vivo by fresh-cut apple slices (Song et al. Hexanal not only enhanced the aroma of fresh-cut apple slices, but it also reduced enzymatic browning at the cut surface as well as inhibited molds, yeasts and mesophilic and psychrotrophic bacteria in Ganny Smith? slices stored at 15?C (Lanciotti et al. Research is currently in the initial stages for the use of this compound on fresh-cut fruit products. Methyl jasmonate is a volatile, naturally occurring compound found in many plants and has been reported to have hormone-like activity at very low concentrations. Exogenously applied methyl jasmonate has been shown to be very effective in reducing mold growth on fresh-cut celery and peppers and may, in the future, have applications as a naturally derived fungicide (Buta and Moline, 1998).

Sensory shelf life was extended 7?29 days, in part due to reduced aerobic microbial plate counts. Peeled packaged citrus products have a shelf life of approximately 17?21 days, but? Edible wax microemulsion coatings (up to 12% solids) reduced leakage of dry-packed grapefruit segments by 80% after 2 weeks and 64% after 4 weeks of storage (Baker and Hagenmaier, 1997). Coatings with carnauba wax were found to be most effective, and coatings were not detected by informal taste panels before or after storage (Baker and Hagenmaier, 1997). Cut apples, treated with acidic coatings, exhibited lower microbial populations, without an overly acidic?
