Measurement of ultrasonographic parameters provides information concerning not only bone density but also bone architecture. We investigated the usefulness of ultrasonographic parameters and bone mineral density for evaluating the probability of vertebral fracture. 397 postmenopausal women (59.1 +/- 6.0 years) with (n = 178) or without (n = 219) atraumatic vertebral fractures were studied. In all women, bone mineral density (BMD) of the lumbar spine was evaluated by dual X-ray absorptiometry (DXA) and speed of sound (SOS); broadband ultrasound attenuation (BUA) and Stiffness in the calcaneus were evaluated by an Achilles unit (Lunar Corporation). Ultrasonographic parameters and BMD were compared by examining the magnitude of the odds ratios, to determine which produces the highest estimate of the probability of odds of fracture, and by examining widths of the respective confidence intervals (CI) to show which estimate of odd ratio is the most precise. The relative risk of vertebral fracture, after adjusting for potential confounders, was 3.5 (CI 2.6-4.8) for BUA; 4.5 (CI 3.2-6.2) for SOS; 5.8 (CI 4.0-8.4) for Stiffness and 7.5 (CI 4.8-11.5) for BMD. Ultrasound (US) parameters were still significant independent predictors of vertebral fracture, even after adjusting for BMD. The relative risk of fracture for a simultaneous decrease by 1 SD of BMD and by 1 SD of each ultrasound parameter was 17.3 (CI 9.4-39.6) for BMD and SOS; 18.3 (CI 8.4-30.6) for BMD and BUA and 22.1 (CI 8.9-52.7) for BMD and Stiffness. Our data suggest that US and BMD provide complementary information which can be combined to improve estimates of vertebral fracture risk. 相似文献

In order to determine the optimal dose of cefepime (CFPM) for respiratory tract infections, a dose finding study was conducted in patients with chronic respiratory tract infections, and the clinical properties of the drugs were compared with those of ceftazidime (CAZ). Each drug was administered by intravenous drip infusion at the dose of 2 g/day of CFPM, 4 g/day of CFPM or 2 g/day of CAZ for 14 days. 1. The overall efficacy rates evaluated by the committee were 82.6% (19/23) for the CFPM 2 g/day group, 85.0% (17/20) for the 4 g/day group and 79.3% (23/29) for the CAZ 2 g/day group, with no statistically significant difference among the three groups. 2. The overall efficacy rates evaluated by the attending physicians were 91.3% (21/23) for the CFPM 2 g/day group, 78.9% (15/19) for the CFPM 4 g/day group and 75.9% (22/29) for the CAZ 2 g/day group, with no significant difference among the three groups. 3. Bacteriological eradication rates were 88.2% (15/17) for the CFPM 2 g/day group, 68.8% (11/16) for the CFPM 4 g/day group and 63.2% (12/19) for the CAZ 2 g/day group, with no statistically significant difference among the three groups. 4. The incidences of adverse reactions were 3.8% (1/26) for the CFPM 2 g/day group, 9.1% (2/22) for the CFPM 4 g/day group and 3.4% (1/29) for the CAZ 2 g/day group, with no significant difference among the three groups. The incidences of abnormal laboratory findings were 37.5% (9/24) for the CFPM 2 g/day group, 15.0% (3/20) for the CFPM 4 g/day group and 3.4% (1/29) for the CAZ 2 g/day group. There was a significant difference among the three groups. 5. Utility rates assessed by the committee were 81.8% (18/22) for the CFPM 2 g/day group, 76.2% (16/21) for the CFPM 4 g/day group and 75.9% (22/29) for the CAZ 2 g/day group. Utility rates assessed by attending physicians were 90.9% (20/22), 78.9% (15/19) and 72.4% (21/29), respectively. There was no significant difference among the three groups. From the above results, it is concluded that the optimal dosage of CFPM is 2 g/day for chronic respiratory tract infections. 相似文献

A number of thrombin mutants have been constructed to investigate the role of Trp96 and the beta-insertion loop for the specificity of thrombin. Thrombin(60D) consists of the replacement of the beta-insertion loop (14 amino acid residues from 59 to 63, including a 9-residue insertion at position 60) with the corresponding four residues in trypsin, Tyr-Lys-Ser-Gly; thrombin(GGG) is a smaller loop mutation in which the residues Tyr(60A)Pro(60B)Pro(60C)Trp(60D) Asp(60E)Lys(60F) of the beta-insertion loop were replaced by Gly-Gly-Gly; thrombin(96S) consists of a point mutation Trp96 --> Ser; and thrombin(GGG/96S) is the double mutant incorporating both changes. Thrombin(96S) clots fibrinogen approximately 3 times more slowly than thrombin, with the two beta-insertion loop mutants, thrombin(GGG) and thrombin(GGG/96S), reacting approximately 3000- and 1300-fold more slowly, respectively. The specificity constant kcat/Km for the cleavage of fibrinopeptide A and fibrinopeptide B by thrombin(96S) was 2.6 and 0.35 microM(-1) s(-1), respectively, compared to 10 and 2.5 microM(-1) s(-1) for wild-type recombinant thrombin, respectively. Kinetic constants were determined for the hydrolysis of H-D-phenylalanyl-L-pipecolyl-L-arginine-p-nitroaniline. The Michaelis constant Km increased approximately 6-fold for thrombin(96S) and >200-fold for thrombin(GGG) and thrombin(GGG/96S) when compared to wild-type recombinant thrombin, while the catalytic constant kcat remained approximately the same. All mutants were more susceptible to inhibition by BPTI than wild-type recombinant thrombin. Clearly, the beta-insertion loop is important for thrombin activity. But the mutation of Trp96 --> Ser can compensate somewhat for the loss of binding at the beta-insertion loop. The deletion of the hydrophobic interaction between Trp96 and Pro(60B)Pro(60C) appears to decrease the stability of the beta-insertion loop, thereby causing a decrease in binding efficiency. 相似文献

Contrary results have been reported regarding prognosis by histologic cell type in surgical treatment for lung cancer. To evaluate whether histologic cell type has influence on prognosis, we separately analyzed the prognostic outcome of patients who had undergone pneumonectomy (n=119) and lesser resections (n=124) for non-small cell lung cancer (NSCLC) between January, 1985 and March, 1996. The pneumonectomy group included 87 (73%) squamous cell carcinoma (Sq), 25 (21%) adenocarcinoma (Ad) and 7 other types with 10 (8%) patients in postoperative stage I of the disease, 29 (24%) stage II, 74 (62%) stage III and 6 in stage IV. The lesser resection group included 45 (36%) Sq, 63 (51%) Ad and 16 other types with 71 (57%) patients in stage I, 9 (7%) stage II, 32 (26%) stage III and 12 stage IV. In patients with stages I-III, the 5-year survival rate was 42.8% for the Sq group and 41.1% for the Ad group in the case of lesser resections and 37.1% for the Sq group and 0% for the Ad group (p<0.05) in the case of pneumonectomy. The poorer prognosis for patients with Ad in the case of pneumonectomy was suspected to be due to the N factor; the percentage of patients with N0-1 was significantly lower in the Ad group than for the Sq group (28 vs 62%, p<0.005). Histologic cell type can be a prognostic factor for patients undergoing surgical treatments for NSCLC. One possible reason for the contrary results on prognosis by histologic cell type among investigators may be due to the mixed results of pneumonectomy and lesser resections. 相似文献

This study proposes a new methodology with harmony search (HS) algorithm and neural networks (NNs) for concrete mix proportioning. The basic procedure for the methodology consists of four steps: (1) constructing a database of mix designs; (2) establishing appropriate models for strength and workability; (3) optimizing mix proportion using the modified HS algorithm; and (4) refining the mixture using NNs. The proposed methodology could be a useful decision-making tool for concrete mix design. 相似文献

The Listeria monocytogenes-carrying rates were 100% for listeriosis patients and 1.3% for healthy humans. The L. monocytogenes contamination rates for retail sliced beef (34.2%) and pork (36.4%) were significantly higher (p < 0.05) than those for cattle (2.0%) and pigs (0.8%) and for cattle (4.9%) and swine (7.4%) carcasses. The percentages of serotypes 1/2a, 1/2b and 4b which are most dominant in human patients were high in isolates from fresh (90.0%) and processed (100%) fish and shellfish and imported natural cheese (96.7%). 相似文献

Plasma and urinary levels of ifosfamide (IF) enantiomers and their metabolites 2-dechloroethylifosfamide, 3-dechloroethylifosfamide, 4-hydroxyifosfamide, and isophosphoramide mustard were determined for control and phenobarbital-treated male Sprague-Dawley rats by using pseudoracemates and GC/MS and stable-isotope dilution analytical methods. For the control rats, the mean AUC for (S)-IF in plasma was greater than that for (R)-IF (R/S AUC ratio, 0.78) and the mean half-life of 41.8 min for (S)-IF was slightly longer than that of 34.3 min for (R)-IF. Phenobarbital pretreatment significantly decreased the AUC values for (R)-IF and (S)-IF, to 21 and 30% of the control values, respectively, and shortened plasma half-lives for both enantiomers [half-life for (R)-IF, 19.8 min; half-life for (S)-IF, 19.4 min]. The urinary excretion values for (R)-IF and (S)-IF were decreased to 41 and 30% of the control values, respectively. The overall amounts of the metabolites in urine were concomitantly increased. Additionally, there were significant reversals in both the R/S AUC ratio and the urinary excretion of 3-dechloroethylifosfamide. Moreover, the enantioselectivity for the generation of 4-hydroxyifosfamide and isophosphoramide mustard disappeared after phenobarbital treatment. These results strongly suggested that the 4-hydroxylation and dechloroethylation of IF enantiomers were mediated by different P450 isozymes or the same isozyme with different stereochemical selectivities. 相似文献

PURPOSE: To clarify the long-term outcomes of Stroke survivors registered for the first onset of Stroke in Yamagata Prefecture and to find out problems in community-based-rehabilitation (CBR). SUBJECTS AND METHODS: The present study was performed using stroke survivors as of September 1, 1991 as subjects from residents registered for the onset of Stroke in 1985 and 1989. The subjects were composed of 1,013 residents registered in 1989 (2 years after onset) and 626 registered in 1985 (6 years after onset). RESULTS: The percent of functionally-independent Stroke survivors at 2 and 6 years (indicated in parentheses) after onset is shown by ADL items as follows: 82% (81%) for urination, 78% (78%) for eating, 78% (78%) for walking, 76% (78%) for dressing, and 66% (64%) for bathing. The lowest percent was seen in Bathing. Percentage of cases maintaining the ability to have functionally-independent ADL for all items examined (expressed as persons independent for personal care) were 62% (60%). Of the the cases 91% (91%) resided at home (their own houses or relatives' houses). With regard to overall locomotion, an item used to evaluation the range of going out doors, 45% (44%) could go out alone to visit neighbors or use public transportation. Among persons independent for personal care, 99% (98%) were living at homo, 70% (69%) used public transportation, 23% (23%) went out alone to visit neighbors and 7% (8%) did not go out. CONCLUSION: The results of the present research indicate a great in CBR for that bothpsychological and social health approaches in cooperation with public health centers, medical centers, and welfare agencies not only for persons with decreased ADL, but also for those maintaining high activity potential. 相似文献

Reverse micelles were employed to test the accuracy of the widely accepted mechanism for alpha-chymotrypsin in a highly structured aqueous system similar to intracellular conditions. Results yielded from spectrophotometrical assays of the alpha-chymotrypsin catalyzed hydrolysis of both p-nitrophenyl acetate (p-NPA) and p-nitrophenyl trimethylacetate (p-NPTA) were kinetically analyzed to determine constants typical of the proposed mechanistic model. This was accomplished through the establishment of a control, i.e. the well studied buffer system, for comparison between the reverse micellular environment and a bulk aqueous solution. Control group results yielded kinetic constants in favor of the proposed mechanism (Km = 1.55 x 10(-5) +/- 1.40 x 10(-6) M for p-NPA and a Km = 4.97 x 10(-6) +/- 2.29 x 10(-7) M, Km(app) = 4.92 x 10(-6) +/- 2.33 x 10(-8) M, k2 = 4.34 x 10(-3) +/- 1.31 x 10(-3), k(cat) = 1.96 x 10(-3) +/- 2.47 x 10(-4), and Ks = 1.60 x 10(-5) +/- 4.61 x 10(-6) M for p-NPTA). In contrast, similar reactions of the enzyme in a reverse micellular system produced kinetic constants atypical to that representative of the textbook mechanism. (Km = 1.59 x 10(-4) +/- 2.70 x 10(-5) M, Ks = -8.67 x 10(-5) +/- 4.46 x 10(-5) M and Km(app) = -4.80 x 10(-5) +/- 7.05 x 10(-5) M for p-NPA and Km = 1.95 x 10(-4) +/- 9.28 x 10(-5) M, Km(app) = -1.79 x 10(-4) +/- 2.36 x 10(-5) M, and Ks = -3.95 x 10(-4) +/- 1.18 x 10(-4) M for p-NPTA). In addition to negative kinetic constants, alpha-chymotrypsin seemed to display characteristics indicative of super-activity and a hysteretic response. Overall, the widely accepted mechanism for alpha-chymotrypsin appeared to fail within the confines of reverse micelles, due to the direct influence of the system's highly structured form. 相似文献

The methods of measuring the affinity constants of anti-HIV-1 p17 monoclonal antibodies (MAbs) using the double antibody methods in the liquid phase and the biomolecular interaction analysis by BIAcore system (Pharmacia Biosensor AB, Uppsala, Sweden) were compared. MAbs, HyHIV1-6, recognizing residues 12-29 (P12-29) of p17 and the naive protein, p17, were used. The kinetic association constants (KAs) obtained using the double antibody method were 2.40 x 10(7) - 1.40 x 10(8)M(-1) for P12-29, and 4.80 x 106 - 1.80 x 10(7) M(-1) for p17. In the BIAcore system where P12-29 or p17 was used as immobilized antigens onto the sensorchip, the KAs were 1.57 x 10(9) - 4.81 x 10(9) M(-1) for P12-29, and 1.52 x 10(9) - 1.21 x 10(10) M(-1) for p17. On the other hand, when MAbs were immobilized onto the sensorchip and P12-29 or rp17 was used as analyte, the KAs for P12-29 and p17 were in the region 3 x10(8) - 3 x 10(9), 1 x 10(8) - 3 x 10(9) M(-1), respectively. These data show that the KAs were higher than those obtained using the double antibody method, however, no significant difference could be observed. Moreover, the KAs obtained for p17 using MAbs as ligand were similar for BIAcore and the double antibody method except for HyHIV2. Therefore, the BIAcore system can be used for the affinity measurement instead of the double antibody method. 相似文献

A power primer. 总被引:13,自引:0,他引:13
One possible reason for the continued neglect of statistical power analysis in research in the behavioral sciences is the inaccessibility of or difficulty with the standard material. A convenient, although not comprehensive, presentation of required sample sizes is provided. Effect-size indexes and conventional values for these are given for operationally defined small, medium, and large effects. The sample sizes necessary for .80 power to detect effects at these levels are tabled for 8 standard statistical tests: (1) the difference between independent means, (2) the significance of a product–moment correlation, (3) the difference between independent rs, (4) the sign test, (5) the difference between independent proportions, (6) chi-square tests for goodness of fit and contingency tables, (7) 1-way analysis of variance (ANOVA), and (8) the significance of a multiple or multiple partial correlation.

We have validated a semi-automatic procedure for the efficient isolation of plasma lipoproteins from 300 microl of whole plasma (actual injection volume 200 microl) by Fast Phase Liquid Chromatography (FPLC). Modified enzymatic assays were established to allow the determination of low concentrations (1-20 mg/dl) of triglycerides and cholesterol using the Beckman CX-5 Autoanalyzer. The sum of the cholesterol contents in the fractions corresponding to low density (LDL) and high density lipoprotein (HDL) can be demonstrated to be highly correlated to values obtained with dextran sulfate/MgCl2 precipitation for HDLc (slope = 0.98, r2 = 0.997) and ultracentrifugation (beta-quant) for LDLc (slope = 1.03, r2 = 0.988). Using pure lipoprotein fractions isolated by ultracentrifugation, linear ranges of detection for HDLc and HDL apoA-I were performed at 18-95 mg/dl and 59-262 mg/dl, respectively. The ranges for LDLc were 41-435 mg/dl and 21-280 mg/dl for LDL apoB. The mean (range) fractional standard deviations for quadruplicate runs for 15 individual plasma samples ranging widely in lipoprotein concentrations were 0.97 (0.29-2.86%) for LDLc (range: 101.5-258.5 mg/dl), 3.67 (0.62-14.11%) for HDLc (range: 27.1-85.1 mg/dl) and 2.19 (0.16-6.56%) for VLDL-TG (range: 6.1-515.0 mg/dl). 相似文献

Iodine-123-N-(3-iodopropene-2-yl)-2beta-carbomethoxy-3beta-( 4-chlorophenyl) tropane (123I-IPT) is a new dopamine transporter ligand that selectively binds the dopamine reuptake sites. Transporter concentrations have been known to decrease in Parkinson's disease patients. The purpose of this study was to evaluate the usefulness of IPT as an imaging agent for measuring changes in transporter concentrations in Parkinson's disease. METHODS: IPT labeled with 6.78 +/- 0.67 mCi 123I was injected intravenously as a bolus into eight normal controls (mean age 41 +/- 12 yr) and 17 Parkinson's disease patients (mean age 55 +/- 9 yr). Dynamic SPECT scans of the brain were then performed for 5 min each over 120 min on a triple-headed gamma camera equipped with medium-energy collimators. Regions of interest were drawn on the middle set of the image at the level of the basal ganglia (BG) for each subject. Time-activity curves were generated for the left BG, right BG and occipital cortex (OCC). The empirical ratios between BG-OCC and OCC, which represent specific-to-nonspecific binding ratios, were computed at various time points. The statistical parameter k3/k4 was estimated by two methods: a variation of the graphic method that derives the ratio of ligand distribution volumes (R[V]) and the area ratio method (R[A]), in which the ratio is calculated from the areas under the specific and nonspecific binding activity curves. RESULTS: The mean (BG-OCC)/OCC ratio for normal controls (3.07 +/- 0.73) was significantly higher than that for Parkinson's disease patients at 115 min (1.10 +/- 0.56) (p = 2.76 x 10[-5]). The mean R(V) and R(A) for normal controls were 2.06 +/- 0.27 and 1.50 +/- 0.15, respectively. The mean R(V) and R(A) for Parkinson's disease patients were 0.78 +/- 0.31 and 0.65 +/- 0.24, respectively. Both R(V) and R(A) for normal controls were significantly higher than those for Parkinson's disease patients (p values for R(V) and R(A) were 1.91 x 10(-8) and 3.46 x 10(-10), respectively). The R(V) has linear relationships with both R(A) and (BG-OCC)/OCC ratio at 115 min. The R(V) has a higher correlation (r = 0.99) with R(A) than it does with (BG-OCC)/OCC (r = 0.93). CONCLUSION: The R(V), R(A) and (BG-OCC)/OCC for Parkinson's disease patients were clearly separated from those of normal controls, and they may be useful outcome measures for clinical diagnosis. The simplest (BG-OCC)/OCC ratio, requiring a single late time point, could be useful in clinical situations, whereas R(V) or R(A) is preferred when the dynamic data are available. The findings suggest that 123I-IPT is a useful tracer for diagnosing Parkinson's disease and studying dopamine reuptake sites. 相似文献

This study aimed to find out the morbid status of Korean physicians living in Korea, as one part of a feasibility study on the Korean physician cohort. It was performed by mail survey using a self-administered questionnaire from Jan. 1, 1995 through Dec. 31, 1995. Study subjects were 21,552 including 17,877 (81.1%) males and 3,384 (15.5%) females. Person based prevalence rate of disease was 17.7% (18.3% for males and 13.8% for females) with the rate increasing with age. The disease group showing the highest prevalence rate was circulatory diseases (5.16%) for males, and respiratory disease (3.13%) for females. The individual disease showing the highest prevalence rates was hypertension (3.77%) for males and allergic rhinitis (2.25%) for females. The person based disease experience rate was 36.2% (36.9% for males, 32.7% for females) with the rate increasing with age. The disease group showing the highest disease experience rate was digestive disease for both sexes (10.05% for males, 7.42% for females). Individual disease showing the highest disease experience rate was hypertension (5.00%) for males and allergic rhinitis (4.08%) for females. There were different ranks of both prevalence and disease experience rate depending on age in both sexes. 相似文献
