    Notes: Background : Meal ingestion has been suggested to reduce susceptibility to the development of gastric tachyarrhythmia, the abnormal activity of the stomach that frequently accompanies nausea.Aim : To determine the types of meal that are most effective in preventing the development of gastric tachyarrhythmia, nausea and the symptoms of motion sickness provoked by a rotating optokinetic drum.Method : Participants received a carbohydrate beverage, a protein-predominant beverage or nothing immediately before exposure to the rotating drum. Subjective symptoms of motion sickness and electrogastrograms were collected during a 6-min baseline period and a subsequent 16-min drum rotation period.Results : Subjective symptoms of motion sickness scores were significantly more severe during the no-meal condition than during either the protein or carbohydrate condition. Central, peripheral and, to some extent, gastrointestinal symptoms were more severe during the carbohydrate condition than during the protein condition. Gastric tachyarrhythmia increased significantly less from baseline to drum rotation during both the protein and carbohydrate conditions than during the no-meal condition.Conclusions : Liquid protein-predominant meals were most effective in suppressing both the development of gastric tachyarrhythmia and the entire spectrum of motion sickness symptoms, including nausea.

    Antibody-based diagnostic for ‘refractory’ periodontitis (2002)

    Notes: Objective: About 10–15% of US adults are ‘refractory’ to therapy for chronic periodontitis. Recently, studies suggest that these patients have elevated lysine decarboxylase activity in the sulcular microbiota. The aim of this study was to determine whether an elevated IgG antibody response to lysine decarboxylase, alone or with antibody to other bacterial antigens and baseline clinical measurements, would predict ‘refractory’ patients with high accuracy.Methods: Chronic periodontitis patients were treated using scaling and root planing (SRP) followed by maintenance SRP and 3-monthly re-examinations. If there was a loss of mean full mouth attachment or more than three sites appeared with 〉 2.5 mm new loss within a year, the subjects were re-treated (modified Widman flap surgery and systemically administered tetracycline). If attachment loss as above recurred, the subjects were ‘refractory’. Baseline clinical measurements and specific antibody responses were used in a logistic regression model to predict ‘refractory’ subjects.Results: Antibody to a peptide portion of lysine decarboxylase (HKL-Ab) and baseline bleeding on probing (BOP) prevalence measurements predicted attachment loss 3 months after initial therapy [pIAL = loss (0) or gain (1)]. IgG antibody contents to a purified antigen from Actinomyces spp. (A-Ab) and streptococcal d-alanyl glycerol lipoteichoic acid (S-Ab) were related in ‘refractory’ patients (R2 = 0.37, p 〈 0.01). From the regression equation, the relationship between the antibodies was defined as linear (pLA/S-Ab = 0) or non-linear pLA/S-Ab = 1). Using pLA/S-Ab, pIAL and age, a logistic regression equation was derived from 48 of the patients. Of 59 subjects, 37 had 2–4 mm attachment loss and were assigned as ‘refractory’ or successfully treated with 86% accuracy.Conclusion: HKL-Ab facilitated an accurate prediction of therapeutic outcome in subjects with moderate periodontitis.

    Value of barium studies for predicting primary versus secondary non-Hodgkin's gastrointestinal lymphoma (2000)

    Notes: Abstract Background: To determine the predictive value of a single lesion versus multifocal disease for differentiating primary and secondary gastrointestinal (GI) lymphoma on barium studies. Methods: Our study group consisted of 90 cases of non-Hodgkin's GI lymphoma from the radiologic archives of the Armed Forces Institute of Pathology in which barium studies had been performed. Each of those studies was reviewed jointly by two of the authors to determine in a blinded fashion whether the patients had a single lesion or multifocal disease (defined as two or more discrete lesions). Medical and pathologic records were then reviewed to determine whether these patients had primary (defined as lymphoma arising in the GI tract) or secondary (defined as disseminated lymphoma with associated GI tract involvement) GI lymphoma. The final clinical diagnosis was then correlated with the radiographic findings to test the hypothesis that a single lesion is more likely to be associated with primary GI lymphoma and that multifocal disease is more likely to be associated with secondary GI lymphoma. Results: Sixty-eight patients had a single lesion in the GI tract on barium studies; 52 (76%) of these patients had primary GI lymphoma and 16 (24%) had secondary GI lymphoma. Another 22 patients had multifocal disease on barium studies; 20 (91%) of these patients had secondary GI lymphoma and two (9%) had primary GI lymphoma. Conclusion: The predictive value of a single lesion for primary GI lymphoma on barium studies was 76%, and the predictive value of multifocal disease for secondary GI lymphoma was 91%. Thus, our data suggest that it is often possible to differentiate these two forms of GI lymphoma on the basis of the radiographic findings.

    The effects of sodium salts on the additive in viscose regeneration process (1961)

    Notes: Various chemical additives are commonly used in viscose to reduce the swelling of the resultant fibers and films. It was found that inorganic sodium salts, introduced into the additive-containing viscose, alter the action of the additive. The following salts, listed in order of the values of gel swelling ratios obtained with them, interfere with the deswelling of the viscose during regeneration: citrate 〉 thiosulfate 〉 tartrate 〉 sulfate 〉 chloride = phosphate = thiocyanate 〉 acetate 〉 nitrate 〉 control. Sodium idodide did not affect the usual deswelling of the films, and sodium sulfide and sodium carbonate caused the films to deswell slightly more than the control sample. It was proposed that the effectiveness of the salts follows a Hofmeister or lyotropic series.

    Isomorphous replacement in a copolyamide system (1961)

    Notes: In a study of isomorphic behavior, it was found that the melting point - composition curve of the copolyamides prepared from caprolactam and p-aminomethylcyclohexylcarboxylic acid was sigmoidal, indicating that the methylcyclohexyl group was interchangeable in the crystal lattice with aliphatic carbon atoms of ω-aminocaproic acid. On the other hand, the benzyl group in the copolymers of caprolactam and p-aminomethylbenzoic acid did not interchange as well, and only partial isomorphism occurred. The analogous meta derivatives, m-aminomethylcyclohexylcarboxylic acid and m-aminomethylbenzoic acid, did not fulfill the spatial requirements of caprolactam. Although V-shaped melting point - composition curves resulted, the disturbance in the crystal network was more severe with the m-phenyl derivative than with the m-cyclohexyl derivative.
