The in vivo efficacy of a newly-developed dental application of a film-forming, chlorhexidine-containing system was examined in beagle dogs. A self-disintegrating film-forming solution was applied three times weekly to the dentitions of 7 out of 13 dogs, which were fed a soft-food diet. Plaque accumulation (Plaque Index) and gingival inflammation ...

beta-Amyloid protein (beta A4) deposition was characterised in the sulci and gyri of frontal cortex in 14 cases of Alzheimer's disease. A quantitative study was made of two distinct plaque sub-types (diffuse and classic) using immunocytochemistry and image analysis using a discriminant function design. As reported previously more beta A4 ...

An enzymatic method, SK-013, was developed for rapid detection of the peptidase activity in subgingival plaque samples. This method was found to have specificity for Porphyromonas gingivalis, Treponema denticola, Bacteroides forsythus, and some Capnocytophaga strains. The purpose of this study was to determine whether SK-013 could indicate the presence of ...

A vaginal obturator was fabricated to be used in combination with implanted catheters to provide microwave hyperthermia and brachytherapy to the vulva and vaginal wall. This site is difficult to heat or irradiate solely with interstitial techniques. The obturator was modified to provide grooves for the mounting of interstitial catheters ...

This article reviews published reports of conventional and radiation burns associated with the use of microwave ovens. Conventional food burns can result from the ingestion of microwave heated food because consumers may overlook the differential temperature gradients within foods and between the food and the container. There are reports of ...

A Taurolin solution has been shown previously to possess antibacterial activity, not only by a bactericidal effect but also by reducing bacterial surface adherence. Such mechanisms may contribute to reduction in dental plaque in the mouth, however this remains to be determined. The present study assessed whether a Taurolin rinse ...

An overview is given on the effects of food processing on the protein digestibility. Beneficial effects of food processing are primarily observed in a range of plant foods containing toxic substances and/or anti-nutrients (legumes, cereals, some seed food). Digestibilities improve by heating, soaking, germination and fermentation. These processing steps reduce ...

1. Resting metabolic rate was determined in Adelie penguins (Pygoscelis adeliae) that had been fed warm and cold ingesta. 2. Post-ingestion metabolic rate was found to be related to food temperature rather than to specific dynamic action. 3. Calorimetric calculations indicate that up to 13% of Adelie penguin daily energy ...

Trypsin inhibitor (TI) occurs naturally in many foods from plants, notably soybean protein products. Heat treatment inactivates TI and improves nutritional quality, but residual TI activity of 5 to 20% remains after typical commercial treatments. Chronic feeding of TI or products that contain TI can inhibit trypsin and chymotrypsin, stimulate ...

Soybean proteins are widely used in human foods in a variety of forms, including infant formulas, flour, protein concentrates, protein isolates, soy sauces, textured soy fibers, and tofu. The presence of inhibitors of digestive enzymes in soy proteins impairs the nutritional quality and possibly the safety of soybeans and other ...

Fixed orthodontic appliances increase the number of retention areas, resulting in increased possibilities for the accumulation of dental plaque. In addition, there is a risk of direct mechanical irritation. In spite of good toothcleaning most orthodontic patients develop generalized moderate gingivitis or an edematous type within one to two months ...

Cell-free hemolymph (serum) of the eastern oyster, Crassostrea virginica, agglutinated Vibrio cholerae, including all O1 serovars and biovars. Seventy-nine other strains of bacteria, including 14 genera and 26 species, were not agglutinated. The A, B, and C factors of O1 antigen were not involved in agglutination. Bacterial agglutinating (BA) activity ...

Neurofibrillary tangles and neuritic plaques are the neuropathological hallmarks of Alzheimer's disease. The latter consist of a core of A4 amyloid protein. We now report that some neurofibrillary tangles ('tombstone tangles') are also A4 immunoreactive. This observation is consistent with the hypothesis that A4 amyloid accumulation is a component of ...

The high market penetration of microwave ovens in the United States and the burst of new food products available for "heating and eating" raises questions about the nutritional impact of the relatively new technology. Based on the information available in the literature, nutrient content and retention of microwave-cooked or reheated ...

The problem of burns after spinal cord injury is described. Chart review was performed on thirty-five known cases. All burns occurred below the level of the lesion (p less than .001). Causes included bathing and showering, food and beverage, and therapeutic and environmental heating devices. We conclude that spinal cord ...

Some confusion exists in the literature whether correlations exist between gingivitis severity and plaque levels as measured by the corresponding indices. The results of a clinical trial and a re-analysis of literature data indicate that a strong statistical correlation exists between the Löe-Silness Gingival Index values and both the Löe ...

Enzyme-linked immunosorbent assays (ELISA) are described for the detection of poultry and pork in cooked and canned meat foods. These assays are based on species-specific, polyclonal antibodies raised against heat-resistant antigens. The heat-resistant antigens were isolated from raw skeletal muscle tissue of pork and chicken and were found to be ...

A low voltage isoelectric focusing (IEF) method for typing human red cell acid phosphatase (ACPl) polymorphism is reported. A clear differentiation of the ACPl*A, ACPl*B and ACPl*C allelic products is obtained by minimizing diffusion of the bands during electrophoresis and during enzyme visualization by using a hydrophilic cellophane film soaked ...

1. Temperature of the scrotum or a similarly sized area of skin on the back of young pigs was changed by means of a thermal pad and food intake was measured. 2. Warming the scrotum to 42 degrees C significantly increased food intake in pigs reared and fed at 25 ...
Kashket S - - 1988
Experiments showed that the intraoral iodide permeability (Ip) method can be used in a reproducible and sensitive manner with solid foods. Ingestion of 5-gram portions of cookies made with defined concentrations of sucrose or fat led to an increased Ip (due to demineralization) of Streptococcus mutans-covered bovine enamel blocks in ...
