Abstract:
Retrospective review comparing the modified Dieterle stain with standard acid-fast stains was performed on seven surgical pathology cases that contained culture-positive mycobacteria infections. Tissues examined comprised cervical and submandibular lymph nodes and soft tissues of the face and chest. Modified Dieterle staining was performed on paraffin-embedded tissue sections, and the results were compared with those of hematoxylineosin stains and auramine-rhodamines and carbol-fuchsin acid-fast stains. The acid-fast stain showed organisms in three of seven cases on initial review and five of seven cases on retrospective review; the auramine-rhodamine stain retrospectively revealed organisms in five cases. In contrast, the Dieterle stain showed organisms in all seven sections on retrospective examination. Dieterle stains revealed either beaded bacilli or nocardia-like filamentous organisms, sometimes with abundant granular debris possibly representing degenerative organisms. In three cases in which bacteria were readily apparent with the Dieterle stain, only rare organisms could be identified with the acid-fast stain. The modified Dieterle stain was more sensitive than the acid-fast stain in the identification of mycobacteria in pediatric specimens, and its use is recommended in cases with necrotizing granulomas. However, its specificity is limited by morphologic similarities of the organisms to those of nocardiosis and cat scratch disease.

Abstract:
Stain remover is used to remove or masks stain from textiles. Two types of textile stain removers were compared in this study; store bought and home prepared types. Due to the environmental and health issues associated with commercial household cleaners, as well as costly, there have been attempts by consumer especially housewives to prepare cleaning products by using materials which can be found in the kitchens. Hence, the main objective of this study is to compare the effectiveness of home prepared textile stain remover with commercial stain remover by assessing the stain properties on cotton and polyester fabrics. Two different brands of stain remover and easily found materials were applied on these two fabrics. The stains on the fabrics were then assessed according to AATCC Test Method 130 and by using chromameter for the intensity of the stain after cleaning. The results showed that, for the cotton fabric, the most effective stain remover is Commercial Brand 1. Commercial Brand 1 and vinegar with baking soda demonstrated an encouraging effect on polyester fabric. The commercial textile stain remover shows great cleaning effect on both cotton and polyester, while home prepared stain remover has limited ability to clean the stains on cotton. However, its cleaning effect on polyester is equivalent to commercial product.

Abstract:
A comparison was made between the acridine orange stain, gram stain and methylene blue stain for direct microscopic counts (DMC) of microorganisms in gravy mixes, spices, cocoa products and baby foods. Bacteria were detected in 96% (45/47) of the samples stained with acridine orange, 64% (30/47) for the gram stain and 66% (31/47) for the methylene blue stain. In most instances, acridine-orange smears showed higher numbers of bacteria than the traditional stains. The staining quality of the acridine orange was better than the conventional stains with bacteria, yeast cells, and mold hyphae fluorescing very differently from the background. The results indicate that direct staining with acridine orange is better than the traditional methods for estimating bacterial numbers in such foods.

Abstract:
Extrinsic stain resides in the dental pellicle and can be caused by introduction of chromogenic materials or therapeutic agents into the oral cavity. In contrast, intrinsic tooth stain is found within the tooth structure and can be caused by a variety of agents, including hematological and developmental abnormalities and drugs such as tetracycline. The mechanisms of extrinsic stain formation differ with respect to the causative agent. For example, stain induced by chlorhexidine (CH) can be explained by an increased rate in the non-enzymatic browning reactions occurring at the pellicle surface, while food stains are retained on the surface via ion exchange mechanisms. Although most extrinsic dental stain can be removed by abrasive and/or surface-active materials, removal of certain types of surface stain, e.g., staining due to cationic antimicrobial agents, requires specific agents such as aminoguanidine to reduce the stain. A broad-spectrum approach to reduce both intrinsic and extrinsic dental stains clinically requires oxygenating agents. To evaluate this approach and understand the mechanisms of stain removal, we developed a spectroscopic method for measuring stain in vivo. A series of clinical studies was performed to evaluate stain removal by the agents. The results showed that carbamide peroxide in combination with surfactants and anti-redeposition agents, e.g., sodium pyrophosphate, was more effective in bleaching dental stain compared with carbamide peroxide alone. A detailed examination of the tooth structure by microhardness measurements, x-ray photoelectron spectroscopy, and scanning electron microscopy showed that stain decolorization with this system did not have any adverse effects.

Abstract:
Two new silver stains have been developed in our laboratories to stain, and possibly identify without culture or immunocytochemical staining, Gram(-) bacteria. The first is the PATS reaction which positively stains Gram(-) bacteria (Figs. 1, 2) including those like spirochetes which are difficult to culture. Another stain for Gram(-), as well as Gram(+), bacteria is a variation of the Gram stain. Ordinarily to stain Gram(+) bacteria, and not Gram(-) bacteria, the crystal violet stain is removed from Gram(-) microbes by rinsing with alcohol/acetone. If this rinse step is omitted, the crystal violet iodide remains attached to both the (+) and (-) microbes. It can then be rendered insoluble, electron opaque and conductive by treatment with silver methenamine solution under microwave irradiation. This procedure has been found especially useful in certain cases to demonstrate spirochetes; it appears to be a more effective silver stain than the PATS reaction for Treponema pallidum, the microbe causing syphilis.

Abstract:
OBJECTIVE: To investigate whether the presence of mucin defines a combined hepatocellular-cholangiocarcinoma or merely a variant of usual hepatocellular carcinoma (HCC).METHODS: From 1979-92, 124 cases of usual HCC were studied at Niigata University Hospital, Niigata City, Japan, and several affiliated hospitals. Histological diagnoses were determined according to World Health Organization (WHO) criteria. Hematoxylin and eosin stain, periodic acid-Schiff (PAS) stain, PAS stain after diastase digestion (D-PAS) and silver stain tests were performed. Cases containing D-PAS-positive substances were also stained by Alcian blue (AB) stain, high iron diamine (HID) stain and concanavaline A paradox-3 type (ConA3) stain. The classification of mucin was determined by AB, HID and ConA3 stains.RESULTS: Mucin was recognized in the area of HCC by mucin stains in 25 of 124 cases. Two forms of mucin existence were classified: extracellular and intracellular. Mucins were classified by histochemical stains into three types: sulfomucin, sialomucin and neutral mucin.CONCLUSIONS: According to the WHO histological classification of primary carcinoma of the liver, mucin existence is characteristic of intrahepatic cholangiocarcinoma. But if mucin exists in morphologically usual HCC, it is better to diagnose it as a variant of HCC (with mucin) rather than as a combined hepatocellular-cholangiocarcinoma.

Abstract:
Near infrared (NIR) spectroscopy was used to analyse fabric stain samples used in a fabric stain prespotter test in which a colorimeter and human panels were used to evaluate the cleaning ability of the prespotters. The purpose of this was to see if the NIR results compared well with the other two techniques and could then be used instead for fabric stain analysis. NIR/visible instruments offer several advantages including determination of coloured and uncoloured components of the stains, ease of comparing the stain before and after cleaning, fast, accurate, reproducible and quantitative analysis, and computer data storage for later comparison. Although the samples were not specifically prepared for this determination, the NIR did give comparable results to the other two techniques for many of the stains analysed.

Abstract:
Abstract Flow cytometric approaches can resolve cell position in the cell cycle based on DNA content, and these analyses are widely used in the study of cell growth, cell cycle regulation, and oncology. These applications require dyes that bind to DNA in a stoichiometric manner and which, with the exception of some UV-excited dyes like Hoechst 33342, require fixation, permeabilization and RNAse treatment for reproducible results. The Vybrant® DyeCycle™ stains are DNA-selective, cell membrane-permeant dyes that show greatly-enhanced fluorescence when bound to DNA. DyeCycle violet stain can be excited by a 405 nm laser, DyeCycle green stain by a 488 nm laser, and DyeCycle orange stain by either 488 nm or 532 nm lasers. (Figure 1) No fixation, permeabilization or addition of RNAse is required for stoichiometric binding of the dye to DNA. These dyes show similar performance on live Jurkat cells to Hoechst 33342 and DRAQ5: G0/G1 peak CV generally less than 6% and G2/G1 ratio greater than 1.8. The DyeCycle stains have been tested on a variety of cells: Jurkat, CHO, NIH 3T3, HL60, HEK cells, and peripheral blood leukocytes. Staining was optimized by cell type using time, temperature, cell concentration and dye concentration. The dyes can be used on cells in the presence of media components, including serum and divalent cations. Cells with damaged membranes exhibit different DyeCycle stain uptake patterns from live cells and can be excluded from analysis with spectrally-resolved viability dyes, such as SYTOX® blue and SYTOX red dyes. The DyeCycle stains have been used with antibody staining against surface antigens to evaluate the cycle profile of subpopulations. Generally, antibody conjugates with red-emitting fluorophores, such as allophycocyanin and phycoerythrin tandem fluorophores, were used because the required concentrations of the DyeCycle stains produced significant emission across fluorescein and phycoerythrin detection channels. The DyeCycle stains have also been combined with viability and apoptotic markers in testing of cells induced to apoptosis with camptothecin. DyeCycle orange stain, in particular, was found to define a sub-G0 population in late apoptotic cells. Finally, the DyeCycle stains cause some retardation of cell division, but do not demonstrate the toxicity observed with DRAQ5. The adherent cell lines, HEK and NIH 3T3, were stained with DyeCycle violet stain and DyeCycle orange stain, respectively before being were sorted under sterile conditions based on G0/G1 and G2/M population fluorescence. Sorted populations demonstrated the appropriate fluorescence when verified by reanalysis, and all sorted populations attached normally and expanded over 1 to 3 days post-sort. DyeCycle stains allow resolution of cell cycle information in viable cells against the dynamic background of cell activity using common lasers, as well as the ability to sort cells based on position in the cell cycle.

Abstract:
A number of stains and stain combinations have been identified that, when used with the hydrophilic resin Lowicryl K11M, produce marked improvements over aqueous uranyl and lead salts (UA-Pb) in terms of low granularity, specificity, and range of components contrasted. Three test specimens, tobacco mosaic virus (TMV), starfish sperm, and cultured mouse fibroblasts, were used to evaluate stain characteristics. UA-Pb showed a preference for nuclei acids, which were stained specifically by osmium ammine-B at pH 1.5. A number of stain combinations in which UA was followed or preceded by salts containing barium, manganese, tungsten, molybdenum, and vanadium provided excellent staining of protein-containing components, each stain combination being unique in terms of the degree to which specific components were discriminated. These stains were particularly effective for visualizing internal components of the nucleus where a number of fibrillar and particulate structures not seen with UA-Pb were well contrasted.

Abstract:
The colonisation of freshly sawn Corsican pine lumber by sapstain and mould fungi was investigated at a sawmill in Hampshire, UK. Three repeat trials encompassing the different seasons of the year were carried out over two years. Results show that fungal colonisation of sawn lumber is dependent on the effect of time of year. Sawlogs were stored for different intervals up to 16 weeks before conversion to boards. Boards were then stored for up to 12 weeks after milling and sampled every 4 weeks to determine the effect of timber ageing on fungal colonisation up to 28 weeks after felling. The metabolic activity of wood cells over the period after felling of the original tree was also measured. It was evident that the defacement of boards reached maximum levels after 12 weeks exposure irrespective of seasonal influences. Initial levels of fungal growth on lumber were reduced if the boards were milled from logs stored for a period prior to conversion. Investigations into the metabolic activity of the wood cells revealed significant levels of respiration taking place up to 28 weeks after felling of the original tree including 12 weeks post-conversion into boards. Boards were used to make a nested stack arrangement allowing plastic tanks top be placed in the centre. The tanks contained a sub-sample of the full-size boards in order to investigate insect activity and effects of gammairradiation. A total of 115 insect species representing 16 of the 34 British orders were collected during the trials. Seventy-two percent of these insects were collected from within the stacks of lumber and investigations using sealed tanks containing boards showed that the insects could influence the fungal colonisation of sawn lumber. Despite the relatively short length of the trials, a succession of insect colonisation from fungivores through to predators and detritivores was recorded. Boards, which were sterilised by gamma-irradiation, were preferentially colonised by mould fungi and subsequent internal staining was confined to the outer surface. Trials with short-length billets allowed the wood-colonising ability of selected sapstain fungi to be investigated under controlled conditions following sterilisation by gamma-irradiation or autoclaving, and storage at 30°C and 20°C. Lesion formation in gamma-irradiated tissue was solely due to the fungus potentially conditioning the wood for colonisation. Colonisation studies also revealed that different fungi exhibit different strategies enabling them to infect timber. Pathogenic species demonstrated a relatively fast initial growth rate to establish themselves before triggering any host anti-fungal responses in the wood. The characteristic lesions created in the billets were investigated using light and electron microscopy to reveal hyphal invasion and or/ wood cell modifications. Respiratory activity of the lesions was elucidated using radioactively labelled glucose allowing the metabolic pathways to be ascertained and demonstrated that wood tissue in the apparently healthy regions adjacent to the lesions reacted as if infected. Future work considers the possibility of biocontrol, using insects in combination with gamma-irradiation of sawn lumber and also further investigations into the reaction zones produced by the fungus growing in the wood.

Abstract:
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2001.
Includes bibliographical references.
In this thesis, a novel stain free detection system for slab gel electrophoresis is examined. Currently, stained techniques are used to identify electrophoretic bands in gels. The stains utilized in these methods involve health risks since they are mutagenic. Also stains like EtBr are intercalating agents meaning they wedge themselves into the grooves of DNA and stay there. Since this includes a physical contact the stains remain in the DNA at the end of the experiment. This makes further use DNA very difficult. The stains need to be removed by chemical techniques which are timewise very costly. Also these operations are very inefficient, retrieve rates are very low which leads to waste of most of the analyte. The specific method we addressed aims to eliminate the use of any kind of stains and therefore inherently increase the end product efficiency. The method introduces the absorption method as the means of detection. The physical law governing the absorption technique is the Beer-Lambert Law. The Beer-Lambert Law defines the linear relation, which correlates absorption value to the analyte concentration, path length of the light and wavelength-dependent absorptivity coefficient. Although the proposed method is intended to apply to all kind of different analytes, to achieve primary goals and prove the feasibility of the method, as the first step detection of DNA molecules are targeted. Hence absorption pattern at a wavelength of 254 nm (which is characteristic absorption peak for DNA) is examined. After the method is proven to work robustly, it will be extended to all kind of different analytes. The unique approach used in the proposed detection system is the use of a scanning technique incorporated with absorption technique utilizing a high QE (Quantum efficiency) CCD camera as the detector. Experiments have been performed to determine the only unknown parameter -wavelength-dependent absorptivity coefficient a([gamma])- in the Beer-Lambert Law. The value of a([gamma]) is dependent on the wavelength and also on the transmission media. In our case wavelength of interest is 254 nm and the specific transmission media is agarose gel with 0.8% concentration. Each lane in the agarose gel is scanned under UV light and transmittance values at 254 nm are recorded as a function of position. The recorded data are processed to see the absorption pattern along the lane. The drop in the signal indicates the existence of a DNA band. Experiments have been performed on three different agarose gels, which are 4 mm thick, and with 0.8% concentration. The value of wavelength-dependent absorptivity coefficient a([gamma]) was determined within an error margin. The resolution of the method was found to be 4 ng/[mu]l.

Abstract:
In recent years, deconstruction theory has emerged as a key method for exploring public address, organizational culture, and literary discourse. Deconstruction theory encourages tearing apart hierarchy and established order to gain insights about the artifact being studied. Furthermore, the theory questions surface or superficial messages and encourages the reader to explore signals hidden below the surface. Deconstruction discounts context and places faith in experience. Using the early plays of Samuel Beckett, this research explores deconstruction as a method to create messages. This new perspective transports deconstruction from a set of theoretical concepts into basic assumptions that enhance communication. This study suggests that deconstructive inventors use processes previously associated with deconstructive criticism to reveal their own beliefs. Furthermore, this study correlates deconstructive invention with rhetorical tropes – metonomy, synecdoche, metaphor, and irony – to create depiction-based persuasion, which asks the rhetor to suspend logic and evoke emotional response.

Abstract:
Currently, laser treatments for Port Wine Stain (PWS) lesions are considered the choice therapy, but response is poor or treatments are ineffective for around half of patients. It is proposed in this thesis that improvements to the effectiveness of laser treatment can be achieved through the acquisition of estimated PWS vessel number density, depths and diameters for each individual lesion. Information regarding PWS vessel architecture is found to be contained within the colour of the lesion. Presented in this thesis is a method of extracting this information through colour measurements and the inverse application of a skin model. Colour measurements are performed on 14 participants using a Konica-Minolta CM2600d spectrophotometer employing a xenon flashlamp illumination source and an integrating sphere. Light transport is simulated through an 8 layer mathematical skin model inclusive of horizontal, pseudo-cylindrical PWS blood vessels using a new Monte Carlo programme. Within the programme, model parameters were adjusted in an iterative process and skin colour was reproduced with a mean discrepancy of 1.9% reflection for clinically normal skin (24 datasets) and 2.4% for PWS skin (25 datasets). The programme estimated anatomical properties of the measured regions of skin, yielding epidermal melanin volume fractions from 0.4% to 3.3% and mean melanosome diameters from 41 nm to 384 nm across the participant group. The response to laser treatment was assessed for 10 participants through colour measurements taken immediately before and at least 6 weeks after treatment and through expert analysis of photographs for 9 participants taken at these times. Treatment response was not found to correlate directly with the pre-treatment melanin parameters estimated by the programme. Mean depths, diameters and number densities of PWS vessels were also estimated by the programme before and after treatment. These parameters were compared to data obtained from Optical Coherence Tomography (OCT) images for 5 participants. Number densities and diameters predicted by the simulation varied by no more than 10% from the values determined by OCT for 4 and 5 out of 7 regions respectively. Mean depths predicted by the simulation did not correspond with those determined by OCT however. This may be a result of the limited contribution of deeper vessels to the colour of PWS skin. Predicted PWS parameters were compared to treatment response assessed by colour measurement for 10 participants and by photographic analysis for 9 of these. Predicted vessel number densities were not found to correspond with treatment response. Vessel diameters predicted by the simulation correlated with treatment response when compared with the pulse lengths selected for treatment. Optical coefficients derived from the skin model were used to estimate appropriate laser treatment radiant exposures at the predicted mean vessel depths and these radiant exposures corresponded strongly with the treatment response. Suggestions for improvements in the predictions of melanosome diameters through changes in the adjacent skin minimisation procedure within the programme are discussed. The apparent underestimation of PWS blood vessel number densities and mean depths (compared to biopsy studies) may be a result of the reduced influence of deeper PWS vessels upon skin colour. Further investigation, including modifications to the PWS vessel minimisation procedure within the programme, would be necessary to determine whether improvements in these predictions may be achievable. The results of the study show that the new Monte Carlo programme is capable of extracting, from measurements of skin colour, realistic estimates of PWS skin characteristics which can be used to predict treatment response and therefore inform treatment parameters on an individual PWS.

Abstract:
Addition of nanopacticles in a base solvent leads to suspensions with enhanced physiochemical properties, compared to base solvent. This new type of suspensions is called nanofluids, with applications ranging from biomedicine to automotives. As a consequence extensive research is being conducted in the field, in particular, on the evaporation of these fluids as it leads to well-defined and highly ordered coffee-rings. However, the exact physics governing this phenomenon remain elusive. The goal of this experimental investigation is to elucidate how various parameters affect the progression of nanofluid coffee-stain formation. Examination of the coffee-ring structuring, produced by the free evaporation of sessile droplets containing nanoparticles, revealed an unexpected, disordered region at the exterior edge of the ring. A self-assembly mechanism with two components, particle velocity and wedge constraints, was proposed to describe the deposition of particles at contact lines of evaporating drops. Environmental pressure was used as a method to control particle crystallinity in the coffee-rings. Essentially, evaporation rate and pressure were found to be inversely proportional. Macroscopically, lowering pressure led to a transition from “stick-slip” to constant pinning. Nanoscopically, lowering pressure promoted crystallinity. Findings supported the proposed, in this thesis, particle self-assembly mechanism. Particle aspect ratio and flexibility were subsequently examined. Pinning strength was found to be a function of particle aspect ratio and rigidity, leading to constant pinning. The proposed, in this thesis, particle self-assembly mechanism was found to be applicable to a variety of aspect ratios and flexibilities. Lastly, particulate crystals grew following different pathways depending on particle flexibility.

Abstract:
The forensic examination of wounds is one of the key elements of analysis performed by forensic anthropologists and forensic pathologists. Gross examination and histological analysis can be used to determine the timing of the wound and its cause. While forensic pathologists are trained to analyze hard and soft tissue wounds, forensic anthropologists, bioarchaeologists, and paleopathologists, focus on hard tissue. Forensic anthropologists have the added benefit of potentially working with residual soft tissue and would benefit from the incorporation of microscopy techniques that take advantage of the soft tissue to better understand perimortem events. Little research has been published that examines if any healing processes, the defining characteristic of an antemortem wound that do not progress beyond the time of death, are preserved within the tissues beyond death and how long they may be visible. The objectives of this study were to examine if the use of multiple stains will allow earlier visualization of healing processes in skeletal fractures than gross examination and to observe the length of time microscopic healing structures remain visible after death. A total of 224 slides from 19 specimens representing both fractured and un-fractured bones for control samples were taken from nine autopsied individuals at the Hillsborough County Medical Examiner's Office and analyzed using four stains: Hemotoxylin and eosin (H&E), trichrome, Prussian blue, and elastin stain. Slides were analyzed using a set of 14 scored variables and evaluated with nonparametric statistical tests and cluster analyses. H&E, trichrome, and elastin stains were useful in examining wound age and survival time categories were significantly different for presence of elastin and presence of hemorrhage. H&E and trichrome stains proved useful for observing residual healing structures after death and time cohorts after time of autopsy were significantly different for 11 variables. Results from this study support further testing with larger sample sizes, including samples with a wider range of survival time, to better predict survival times of fractures and time since death.
