Abstract: Evidence is presented for the baryonic $B$ meson decay $\bar{B}\rightarrow D^0 \Lambda \bar{\Lambda}$ based on a data sample of $471 \times 10^6$ $B\bar{B}$ pairs collected with the {\it BABAR} detector at the PEP2 asymmetric $e^+e^-$ collider located at the SLAC National Accelerator Laboratory. The branching fraction is determined to be $\mathcal{B}(\bar{B}\rightarrow D^0 \Lambda \bar{\Lambda}) = (9.8^{+2.9}_{-2.6} \pm 1.9)\times 10^{-6}$, corresponding to a significance of $3.4$ standard deviations including systematic uncertainties. A search for the related baryonic $B$ meson decay $\bar{B}\rightarrow D^0 \Sigma^0 \bar{\Lambda}$ with $\Sigma^0\rightarrow\Lambda\gamma$ is performed and an upper limit $\mathcal{B}(\bar{B}\rightarrow D^0 \Sigma^0 \bar{\Lambda} + \bar{B}\rightarrow D^0 \Lambda \bar{\Sigma}^0) < 3.1 \times 10^{-5}$ is determined at $90\%$ confidence level.

Abstract: The purpose of this study was to examine the longitudinal effects of body size over- and underestimation and other psychosocial factors on the risk for onset of overweight (OW) or obesity (OB) 1 year later among US adolescents. Participants with non-missing height and weight were drawn from the first two waves of the National Longitudinal Study of Adolescent to Adult Health (n=13 568). Multinomial logistic regressions were conducted to assess longitudinal risk factors for OW and OB onset, controlling for baseline weight status, age, race/ethnicity, parent education and family structure. Analyses were stratified by sex. Compared with accurate body size perception, body size overestimation increased the relative risk (RR) of OW onset among women and men (RR=3.34, confidence interval (CI)=2.39–4.68; RR=6.01, CI=4.09–8.83, respectively, P

Abstract: We describe searches for B meson decays to the charmless vector-vector final states ωω and ωϕ with 471 × 10^6B¯B pairs produced in e^+e^− annihilation at √s = 10.58 GeV using the BABAR detector at the PEP-II collider at the SLAC National Accelerator Laboratory. We measure the branching fraction β(B^0 → ωω) = (1.2 ± 0.3^(+0.3)_(-0.2) × 10^(−6), where the first uncertainty is statistical and the second is systematic, corresponding to a significance of 4.4 standard deviations. We also determine the upper limit β(B^0 → ωω) < 0.7 × 10^(−6) at 90% confidence level. These measurements provide the first evidence for the decay B^0 → ωω, and an improvement of the upper limit for the decay B^0 → ωϕ.

Abstract: There are two established methods for extending the crystal-field model for 4f N configurations. One is to add two-electron correlation crystal-field operators, the other is to extend the basis set to include more configurations. We consider the case of Pr 3+ ions in LiYF 4 and show, by projecting the configuration-interaction Hamiltonian into the 4f 2 configuration, that in this case the two approaches give very similar results.

Abstract: In order to explore the effect on bone marrow macrophages of liposome-encapsulated dichloromethylene diphosphonate (Cl2MDP), mice were injected intravenously with a preparation of such liposomes at a dose known to deplete spleen and liver macrophages. Two days later, the macrophages in the marrow of the femoral bones were quantified by flow cytometry using a macrophage-specific monoclonal antibody (F4/80), and their ultrastructure and phagocytic activity towards zymosan particles was assessed. To determine the effect on erythropoiesis of liposome-encapsulated Cl2MDP-induced changes in bone marrow macrophages, red blood cell parameters and the formation of erythroid burst-forming unit (BFU-E)-derived colonies in vitro were evaluated. In mice injected with liposome-encapsulated Cl2MDP, there was a 54% and 67% decrease in the total number of bone marrow macrophages as compared to uninjected controls and mice treated with empty liposomes, respectively. Moreover, residual macrophages showed an abnormal ultrastructure, with reduced numbers of crystalloid inclusions and increased numbers of large myelin figures. However, the phagocytic activity of these cells was unimpaired or slightly enhanced. In mice injected with liposome-encapsulated Cl2MDP there was an approximately 60% decrease in the percentage and total number of circulating reticulocytes and a 54% reduction in the BFU-E number, demonstrating deregulation of erythropoiesis under conditions of macrophage loss and impairment. The results suggest that mice treated with liposome-encapsulated Cl2MDP are a model for studying the role of macrophages in erythropoiesis.

Abstract: Background and Aims: Protein kinase C (PKC) plays a key role in the alteration of signal transduction in the liver, which may contribute to the development of liver cirrhosis. The aim of the present study was to examine the subcellular redistribution of PKC isozymes in rat liver cirrhosis, which is induced by two different cirrhotic chemical agents, carbon tetrachloride (CCl4) and thioacetamide (TAA). Methods and Results: Thioacetamide and CCl4 were administered to rats for 8 and 30 weeks, respectively before rats were killed and autopsies performed at 9, 20 and 30 weeks later. The TAA induced a fibrotic pattern in the liver that differed from that produced by CCl4, notably in the formation of fibrous connective tissue and the proliferation of bile ductule cells. Cholangiofibrosis and clear-cell foci were also observed in TAA-treated rats at 30 weeks. Histological examination revealed that severe cirrhotic changes were present 9 weeks after the commencement of CCl4 treatment and 30 weeks after TAA treatment. Discussion: When the subcellular redistribution of PKC isozymes (PKCα, -β1, -δ, and -ɛ) was examined, all the PKC isozymes in CCl4-treated rats were found to be translocated to the membrane fraction, which may mean PKC activation, and then downregulated by proteolytic degradation after 9 weeks of treatment, which coincided with peak cirrhotic changes. All rats treated with CCl4 recovered to the control level after 20 weeks of treatment. In the case of TAA-treated rats, PKC isozymes were translocated to the particulate fraction of the liver after 9 weeks of treatment and this persisted in most of the rats for the duration of the experiment. Conclusions: From these results, it would appear that PKC translocation preceded morphologic changes, and that an altered subcellular distribution of the PKC isozyme may be associated with the response to liver damage and carcinogenesis.

Abstract: The congenital forms of dyserythropoiesis comprise a group of hereditary disorders characterized by ineffective erythropoiesis as the predominant mechanism of anaemia and morphologically abnormal erythroblasts. Up to now three major forms and four variants have been described. Group VII is characterized by dyserythropoiesis with intraerythroblastic precipitation of a non-globin protein. Here we described a case of dyserythropoietic anaemia presenting neonatally and requiring regular blood transfusions. Optical and electronic microscopy studies confirmed that this case was very similar to those in two previously reported transfusion-dependent patients with an unusual type of congenital dyserythropoietic anaemia.

Abstract: Lipase B (GCB) produced by the fungus Geotrichum candidum CMICC 335426 is known for its high specificity towards cis-Δ9 unsaturated fatty acids. The wild-type lipase (not genetically modified) as well as the lipase obtained by heterologous expression of the corresponding gene in Pichia pastoris (genetically modified) were studied in a process aiming to produce an oil containing very little saturated fatty acids (SAFA). The approach described in this paper is based on the selective hydrolysis of sunflower oil (12% SAFA) using the G. candidum type B (GCB) lipases. Depending on the lipase input, up to 60% w/w degree of hydrolysis was obtained within 6–8 h. Because of the high specificity of the GCB lipases (specificity factor ∼30), the level of unsaturates in the free fatty acid fraction was >99% w/w. In contrast with literature data, no loss of specificity was observed, even at the highest degree of hydrolysis obtained. Though both GCB lipases are stable at 30°C, the rate of hydrolysis decreased considerably during the process. Product inhibition as well as time-dependent deactivation (half-life ≈2 h) were shown to be involved. After separation of the oil phase, the unsaturated free fatty acids were recovered from the mixture by evaporation and reconverted to triglycerides by enzymatic esterification with glycerol. Because the GCB lipases have a very low efficiency for esterification, this reaction was carried out with immobilized Rhizomucor miehei lipase. Under continuous removal of the water generated during the process, >95% triglycerides were obtained in less than 24 h. Standard deodorization resulted in an odorless, colorless, and tasteless oil with less than 1% SAFA.

Subjects: Biochemistry, QD415-436
Abstract: Normal and streptozotocin (STZ)-diabetic rats were studied in order to examine the effects of altering the type of dietary protein on cholesterol homeostasis. Rats were fed a non-purified or a purified diet containing either casein or soybean protein. The results obtained on the specific aspects of lipid metabolism were remarkably similar in control rats fed the non-purified (Purina Lab Chow) diet or the purified diet with the soybean protein. However, most of the findings obtained with the above two groups were different from those obtained with rats fed the purified diet containing casein. In the latter group, plasma cholesterol was elevated following a 15-day feeding period as compared to the other two dietary groups. The excess plasma cholesterol in the casein-fed group was found in two lipoprotein fractions with densities of 1.023-1.045 g/ml and 1.045-1.086 g/ml, respectively. The latter lipoprotein fraction was also enriched with apolipoprotein E. The casein-fed animals also showed a lower fractional rate of plasma cholesterol esterification and an abnormal accumulation of cholesterol in the body despite inhibition of cholesterol synthesis in the liver and in the intestines. Twelve to 15 days after the induction of diabetes, plasma cholesterol increased to a similar extent in the rats on all three diets. However, the distribution of cholesterol among the lipoprotein fractions was markedly different. The percentage of cholesterol in fractions of d less than 1.086 g/ml was increased while that carried in the fraction of d 1.086-1.161 g/ml decreased in the rats fed the nonpurified diet and the casein diet. In contrast, there was no change in the distribution of lipoprotein cholesterol between the diabetic and the control rats fed the soybean protein diet. The hepatic synthesis of cholesterol was unaltered in diabetic rats fed the nonpurified diet and the purified diet with soybean protein, but was increased 2.4-fold in diabetic rats fed casein. Intestinal cholesterol synthesis was increased in all three dietary groups. The increase was highest in the rats fed casein and lowest in rats fed soybean protein. The rate of sterol synthesis in the kidneys was not significantly affected by the diet or diabetes. In all three dietary groups diabetes led to an abnormal accumulation of cholesterol in the body. This accumulation was highest in the casein-fed rats and lowest in those fed the soybean protein diet. The cholesterol content of the kidneys was markedly increased by dietary casein.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract: Radial profiles of plasma density and electron temperature have been measured by a fast-scanning probe (FSP) system with various neutral pressures in the MAP-II and DIPS linear devices for the divertor simulation. The probe system is made of three probe tips, two of which is for a Mach probe consisting of two opposite-directional probes, and one is for an emissive probe installed on the pneumatically driven fast-scanning system with stroke of 30 cm. In MAP-II, density at the center has been varied from 1.5 × 10 13 cm -3 to 0.7 x 10 13 cm -3 with pressures of 5.5 to 112 mtorr, while that of DiPS varied from 3.5 × 10 12 cm -3 to 9 × 10 12 cm -3 with pressures of 0.8 to 50 mtorr. Relation of density profile with the working pressure/magnetic field is analyzed by using a simple fluid model. Electron temperature at the center is also measured by the Thomson scattering method and compared with those of FSP, which is varied from 0.6 to 6.5 eV.

Abstract: N-Nitroso-N-(3-keto-1,2-butanediol)-3'-nitrotyramine (NO-NTA) is a product of model browning system generated in the presence of sodium nitrite. The chemical structure of this compound has been confirmed by UV, mass and nuclear magnetic resonance, and infrared spectroscopy in our previous study. A two-stage transformation protocol was used to chemically transform the mouse embryo fibroblasts C3H10T1/2 cells. To initiate transformation, the cells were treated with benzo[a]pyrene (BaP) (0.1 mg/ml), and NO-NTA (0.01, 0.1 and 1 mg/ml) was employed subsequently to complete the transformation process. Malignant transformed foci were formed in BaP-initiated and NO-NTA promoted C3H10T1/2 cells after 8 wk. Cells treated with NO-NTA alone failed to induce transformation. However, cells initiated with BaP and promoted by cells initiated with BaP and promoted by NO-NTA demonstrated oncogenic properties. Cell lines transformed with NO-NTA-transformed colonies exhibited enhanced growth rate, anchorage independence and tumorigenicity in animals relative to parent cells. These results indicate that NO-NTA is a new tumour promoter and may induce tumour promotion by two-stage oncogenesis. Further studies on the mechanism of action of NO-NTA are now in progress.

219. Semiparametric econometric estimators for a truncated regression model: a review with an extension

Author: H. Kim and M.-J. Lee
Subjects: Statistics and Probability, Delta method, Truncated regression model, Covariate, Monte Carlo method, Statistics, Econometrics, Estimator, Asymptotic distribution, Semiparametric regression, Statistics, Probability and Uncertainty, Mathematics, Variable (mathematics)
Abstract: Econometric estimators for a truncated regression model are reviewed. For each estimator, the motivations, the key assumptions, the asymptotic distribution and estimates for the asymptotic variance matrix are presented; also a new estimator is suggested. We select five practical estimators among those, and compare them through a Monte Carlo study where the response variable is simulated but the covariates are drawn from a real data set. Some practical and computational issues are addressed as well.

Abstract: Ultrastructural immunocytochemical studies were performed on sections of bone marrow from three patients with beta-thalassaemia major and two patients with haemoglobin H (HbH) disease. Some sections were reacted with either a polyclonal or a monoclonal anti-human-ubiquitin antibody and the reaction visualized using a gold-labelled secondary antibody. The inclusions of precipitated globin chains found within the erythropoietic cells of all five patients reacted much more strongly than the surrounding inclusion-free cytoplasm with both of the anti-ubiquitin antibodies, indicating that the precipitated globin chains were ubiquitinated. A non-specific reaction between the anti-ubiquitin antibodies and the inclusions was excluded by demonstrating that various other antibodies, including a polyclonal anti-human cathepsin D antibody, did not react with the inclusions. The data suggest that the ubiquitin proteolytic pathway is involved in the degradation of precipitated globin chains in alpha- and beta-thalassaemia.

Abstract: Purpose : To investigate the correlation between established contrast-enhanced computed tomography (CECT) criteria of disease severity in acute pancreatitis and the APACHE (Acute Physiology and Chronic Health Evaluation) II score and to assess the utility of each as prognostic indicators in acute pancreatitis. Materials and Methods : Over a 1-year period, prospective, consensus interpretation of the CECTs of 35 consecutive inpatients was performed with determination of the CECT grade, degree of necrosis, and severity index. The APACHE II score was calculated within 24 h of CECT. Multiple clinical endpoints were recorded: local complications (pseudocyst, abscess, or acute fluid collections requiring urgent surgical or radiological intervention), systemic disease (intensive care unit admission), and duration of hospitalization. Statistical analysis was performed to determine correlations. Results : No statistically significant correlation existed between the APACHE II score and CECT grade, the degree of necrosis, or the CECT severity index. Only the CECT grade and severity index correlated significantly with the occurrence of local complications ( P = 0.0035 and 0.0048, respectively). The APACHE II score was superior to the CECT grade as a predictor of the need for ICU admission ( P = 0.022 vs P = 0.035), and no other CECT criteria was a significant predictor of ICU admission. Conclusion : The preferred clinical and imaging prognostic measures in acute pancreatitis, the APACHE II score and CECT criteria, do not correlate with one another in the commonly encountered, mixed primary and tertiary care population. The mathematical integration of CECT criteria and the APACHE II score fails to yield a predictor of outcome superior to the use of any one measure alone. CECT criteria best define local anatomic abnormality, and are superior to the APACHE II score as predictors of local complications. The APACHE II score is superior to all CECT criteria as an indicator of systemic disease severity (reflected in the need for ICU admission). The most effective initial triage would be immediate APACHE II calculation. Further use of imaging vs clinical assessment can then be individualized.

Abstract: Objective: This study was undertaken to evaluate the potential efficacy of fluorine-18 2-fluoro-2-deoxy- d -glucose positron emission tomography (FDG PET) to detect renal tumours and to characterize indeterminate renal cysts. Subjects and methods: Twenty-six PET scans were performed in 21 patients (14 PET scans in 10 patients with malignant renal tumours and 12 PET scans in 11 patients with Bosniak type 3 indeterminate renal cysts). Pathological proof was obtained in 18 of 21 patients (10 with solid neoplasms, eight with indeterminate cysts). Imaging was performed 1 h after injection of 5–10 mCi of FDG with IV administration of Lasix (10 mg) 20 mins after injection. Two consecutive 9.7-cm image segments were scanned to cover the entire renal areas. Results: PET accurately depicted solid neoplasms as areas of increased uptake in nine of 10 patients. Bilateral renal cell carcinomas were missed in one diabetic patient. All but one indeterminate renal cysts were correctly classified as benign (photopenic areas), but an indeterminate cyst with a 4-mm papillary neoplasm was wrongly classified as benign. There were no false positive PET interpretations. The mean tumour-to-kidney ratio was 3.0 for malignant lesions. Conclusion: We conclude that FDG PET scanning shows promise in the evaluation of indeterminate renal cysts. A positive PET scan in the appropriate clinical setting obviates the need for cyst aspiration. A negative PET scan in conjunction with a negative cyst aspiration offers confirmatory evidence of benignity. Our preliminary results are encouraging and further work is ongoing.

Abstract: A human macrophage line, designated K1m, has been established from peripheral blood. K1m expresses a number of lineage-specific markers as well as a broad array of intercellular adhesion molecules. In particular, K1m expresses high levels of human leucocyte antigen (HLA) class I and class II. In response to ligation of HLA class II (HLA-DR), but not in response to ligation of HLA class 1, K1m forms tighter homotypic aggregates and develops a striking 'stellate' culture phenotype. K1m also expresses Fc receptors for immunoglobulin G (IgG) (CD64, CD32, and CD16) and can be shown to phagocytose polystyrene latex beads, as well as neuroblastoma cells in the presence of tumour-specific monoclonal antibody (mAb). The K1m cell line should therefore prove useful for studying both signalling through macrophage HLA class II and immunophagocytosis.

Abstract: To assess the treatment of continuous data in a sample of obstetric and gynecologic literature.We reviewed articles in Obstetrics and Gynecology published in the first 4 months of 1985 and 1995. Data were tabulated on a data form created specifically for this purpose and reviewed for accuracy.The sample set included 170 variables in 102 original articles from Obstetrics and Gynecology published from January to April 1995, inclusive (group A, contemporary articles), and 117 variables in 89 articles published between January and April 1985, inclusive (group B, historic articles). Fifty-three variables (31% of total variables) in group A and 27 variables (23% of total variables) in group B (chi 2, P = .05) were continuous predictor variables. The historic-period articles (63%) were significantly more likely to represent continuous data only as categoric variables than were articles in the contemporary period (38%) (Fisher exact test, P = .037). Correlation coefficients, r values, were provided where possible in ten articles in the contemporary period (83%) and four articles in the historic period (31%) (Fisher exact test, P = .008). In articles in which continuous predictors were treated only as categoric variables, an emphasis was placed on the findings based only on categories in four of 12 (33%) of these articles in 1995 and nine of 13 (69%) in 1985 (Fisher exact test, P = .05).The treatment of continuous data has improved over the time period reviewed. However, clinicians should be aware that continuous data may be mischaracterized as categoric variables in some journal articles. We hope that in the future, editors will consider requesting r values for all continuous data relations. The quality-of-care implications of using discrete cutoffs of continuous data for patient care should be investigated.

Abstract: The e^+e^−→pp cross section and the proton magnetic form factor have been measured in the center-of-mass energy range from 3.0 to 6.5 GeV using the initial-state radiation technique with an undetected photon. This is the first measurement of the form factor at energies higher than 4.5 GeV. The analysis is based on 469 fb^(−1) of integrated luminosity collected with the BABAR detector at the PEP-II collider at e+e− center-of-mass energies near 10.6 GeV. The branching fractions for the decays J/ψ→pp and ψ(2S)→pp have also been measured.

229. Ordered macroporous platinum electrode and enhanced mass transfer in fuel cells using inverse opal structure

Abstract: Three-dimensional, ordered macroporous materials such as inverse opal structures are attractive materials for various applications in electrochemical devices because of the benefits derived from their periodic structures: relatively large surface areas, large voidage, low tortuosity and interconnected macropores. However, a direct application of an inverse opal structure in membrane electrode assemblies has been considered impractical because of the limitations in fabrication routes including an unsuitable substrate. Here we report the demonstration of a single cell that maintains an inverse opal structure entirely within a membrane electrode assembly. Compared with the conventional catalyst slurry, an ink-based assembly, this modified assembly has a robust and integrated configuration of catalyst layers; therefore, the loss of catalyst particles can be minimized. Furthermore, the inverse-opal-structure electrode maintains an effective porosity, an enhanced performance, as well as an improved mass transfer and more effective water management, owing to its morphological advantages.

Abstract: We measure the mass difference, Δm_0, between the D^*(2010)^+ and the D^0 and the natural linewidth, Γ, of the transition D^*(2010)^+ → D^0π^+. The data were recorded with the BABAR detector at center-of-mass energies at and near the Υ(4S) resonance, and correspond to an integrated luminosity of approximately 477 fb^(-1). The D^0 is reconstructed in the decay modes D^0 → K^-π^+ and D^0 → K^-π^+π^-π^+. For the decay mode D^0 → K^-π^+ we obtain Γ=(83.4±1.7±1.5) keV and Δm_0=(145425.6±0.6±1.8) keV, where the quoted errors are statistical and systematic, respectively. For the D^0 → K^-π^+π^-π^+ mode we obtain Γ=(83.2±1.5±2.6) keV and Δm_0 = (145426.6±0.5±2.0) keV. The combined measurements yield Γ=(83.3±1.2±1.4) keV and Δm^0 = (145425.9±0.4±1.7) keV; the width is a factor of approximately 12 times more precise than the previous value, while the mass difference is a factor of approximately 6 times more precise.

We select a sample of B^0→D^(*-)Xl^+ν decays with a partial reconstruction method and use kaon tagging to assess the flavor of the other B meson in the event. We determine the CP violating asymmetry A_(CP)≡[N(B^0B^0)-N(B^0B^0)]/[N(B^0B^0)+N(B^0B^0)]=(0.06±0.17_(-0.32)^(+0.38))%, corresponding to Δ_(CP) = 1- |q/p|=(0.29±0.84_(-1.61)^(+1.88))×10^(-3).

Abstract: A precise measurement of the cross section for the process e+e- --> K+K-(gamma) from threshold to an energy of 5 GeV is obtained with the initial-state radiation (ISR) method using 232 fb^{-1} of data collected with the BaBar detector at e+e- center-of-mass energies near 10.6 GeV. The measurement uses the effective ISR luminosity determined from the e+e- --> mu+mu-(gamma)gamma_ISR process with the same data set. The corresponding lowest-order contribution to the hadronic vacuum polarization term in the muon magnetic anomaly is found to be a_mu^{KK, LO}=(22.93 +- 0.18_{stat} +- 0.22_{syst}) * 10^{-10}. The charged kaon form factor is extracted and compared to previous results. Its magnitude at large energy significantly exceeds the asymptotic QCD prediction, while the measured slope is consistent with the prediction.

Abstract: We search for the decay Υ(1S)→γA^0, A^0→gg or ss , where A^0 is the pseudoscalar light Higgs boson predicted by the next-to-minimal supersymmetric Standard Model. We use a sample of (17.6±0.3)×10^6 Υ(1S) mesons produced in the BABAR experiment via e^+e^-→Υ(2S)→π^+π^-Υ(1S). We see no significant signal and set 90%-confidence-level upper limits on the product branching fraction B(Υ(1S)→γA^0)·B(A^0→gg or ss) ranging from 10^(-6) to 10^(-2) for A^0 masses in the range 0.5–9.0 GeV/c^2.

We fully reconstruct the hadronic decay of one of the B mesons in the Υ(4S)→BB decay, and search for the B→K^(*)νν decay in the rest of the event. We observe no significant excess of signal decays over background and report branching fraction upper limits of B(B^+→K^+νν)

Abstract: P-SURO II is a hybrid AUV which can be operated in both of ROV and AUV modes. The AUV mode is supposed to carry out some of underwater missions which are difficult to be accomplished by ROV mode due to its tether cable. To complete the underwater missions such as inspection and maintenance of complex structures in AUV mode, the vehicle is required to have high level of autonomy including obstacle avoidance, autonomous navigation, and so on. In this paper, we will discuss some of systematic and algorithmic issues in the development of such kind hybrid vehicles. Experimental studies on the development of underwater hybrid inertial navigation system and SLAM (simultaneous localization and mapping) method in a certain water tank environment are also discussed.

Abstract: Gonadal vein recruitment by collateral veins in patients with renal cell carcinoma is not routinely searched for during abdominal computed tomography. We performed a retrospective view to determine the incidence of gonadal vein recruitment for collateral venous drainage in patients with renal cell carcinoma and we discuss its potential importance.Abdominal CT examinations were available for 58 of 95 patients with renal cell carcinoma identified during a 3-year-period. The presence of collateral veins and recruitment of the ipsilateral gonadal vein was recorded and correlated with the estimated blood loss at surgery.Eighteen of 58 tumours were small (less than 5 cm). Multiple (greater than three) collateral renal capsular veins were noted in 26 of 58 patients and few (less than three) were noted in 11. Recruitment of the gonadal vein (range 4-18 mm, mean 8 mm) was seen in 18 of 58 patients (31%) who all had multiple collaterals. Gonadal vein recruitment was only seen in patients with tumours greater than 5 cm. Mean estimated blood loss at surgery was significantly different (P0.01) in 18 of 58 patients (mean, 1078 ml) with gonadal vein recruitment compared to 40 of 58 patients (mean 304 ml) without distinct visualization of the gonadal vein and compared to 22 of 40 patients with large tumours (mean 368 ml).Gonadal vein recruitment signifies well-developed arteriovenous shunting and high flow collateral venous drainage pathways and may be used as an index of tumour vascularity. This finding may have clinical potential in triaging patients toward pre-operative renal embolization.

Abstract: C ase History A 52-year-old woman presented to the emergency department with an acute onset of severe abdominal cramps, feculent vomiting. and a fever of 103#{176}F (39#{176}C). Her medical history was significant: an appendectomy, a cholecystectomy, and an oophorectomy. A clinical diagnosis of small-bowel obstruction was made. A radiograph of the abdomen revealed dilated, fluid-filled smallbowel loops that confirmed the diagnosis. A chest radiograph revealed lung consolidation and a moderate-sized right pleural effusion (Fig. 1A). The emergency department resident performed a diagnostic thoracentesis without image guidance. Cloudy fluid was obtained. Laboratory analysis of the pleural fluid identifled 3500 WBC/pJ with a differential of 73% polymorphonuclear leukocytes. a pH of 7.15, and a glucose level of 31 mg/dl. An immediate Gram’s stain revealed no organisms. The patient was begun on IV antibiotics empirically that included 400 mg of clindamycin every 8 hr, 240 mg of gentamicin every 24 hr. and 1 g of eiythromycin every 6 hr. Subsequent cultures revealed no bacterial growth. A clinical diagnosis of empyema was made. What criteria are used to make this diagnosis, and do these criteria assist in selecting the appropriate treatment? Dr. Mueller. We employ the widely used criteria defined by Light [ I ] in differentiating patients with simple parapneumonic effusions from those with empyemas. The diagnosis of empyema by Light’s criteria requires one of the following features to be present: gross pus. organisms on Gram’s stain, a pH below 7.0, or a glucose level below 40 mg/dl [2]. Light went on to describe three stages in the evolution of empyema. The first is the exudative stage, which occurs when a focus of infection con

Abstract: Isothermal vapor-liquid equilibrium (VLE) data were measured for the binary systems of nitrogen with 2-methyl-1-pentanol, 1-octanol, or 1-decanol at temperatures from 333.15 K to 453.15 K and pressures up to 100 bar. Henry's constants of nitrogen in these three alcohols were determined by using the Krichevsky-Ilinskaya (KI) equation. The experimental VLE data were also correlated by the Peng-Robinson and the Patel-Teja equations of state with various mixing rules.

Abstract: Ultrathin sections of bone marrow cells from two patients with homozygous beta-thalassaemia, two patients with haemoglobin H (HbH) disease, a patient with congenital dyserythropoietic anaemia (CDA) type III and two patients with severe congenital dyserythropoietic anaemia of an unusual type were reacted with mouse monoclonal antibodies against various globin chains and the reaction visualized using a gold-labelled goat antibody against mouse IgG. The multiple rounded intra-erythroblastic inclusions found in homozygous beta-thalassaemia reacted with the monoclonal antibody against alpha-globin chains but not beta-globin chains, thus confirming that they consisted of precipitated alpha-globin chains. The branching intra-erythroblastic inclusions found in HbH disease and CDA type III reacted with the monoclonal antibody against beta-globin chains but not alpha-globin chains, indicating that they consisted of precipitated beta-globin chains. The two patients with severe CDA had been transfusion-dependent since infancy, had a normal alpha:beta globin chain synthesis ratio or parents with normal red cell indices, displayed prominent dysplastic changes in their erythroblasts, and had intra-erythroblastic inclusions resembling those seen in homozygous beta-thalassaemia. However, unlike those in beta-thalassaemia, the inclusions in these two patients did not react with the monoclonal antibody against either alpha- or beta-globin chains. The inclusions reacted with antibody against zeta-globin chains, but detailed studies in one of the patients indicated that the antigen involved was not zeta-globin. These patients have features not reported in the condition known as dominantly inherited inclusion body beta-thalassaemia and appear to suffer from a novel type of CDA in which the intra-erythroblastic inclusions may consist of some non-globin protein or structurally-abnormal alpha-globin chains.

Abstract: The coprecipitated Mn-Ni-Fe oxalate was prepared from the mixed sulfate solution by optimum pH control. The chemical composition agreed well with that of the starting solution, and the thermal decomposition of the Mn-Ni-Fe oxalate in air below 600 °C led to the direct formation of cubic spinel phase with fine particle size. The sinterability of the calcined powder, the stability of cubic spinel phase and the influence of annealing temperature on electrical properties of the sintered bodies, were investigated.

Abstract: A 22-year-old man underwent an elective laparoscopic cholecystectomy at an outside hospital for recurrent right upper quadrant pain and gallstones. The day after surgery he had bile leakage from an external surgical drain and underwent open exploration. At surgery he was found to have a common duct laceration; a choledochojejunostomy with a T tube bridging the anastomosis was performed. Postoperatively, he continued to have a bile leak from a Jackson-Pratt surgical drain and was transferred to the Massachusetts General Hospital. A T-tube cholangiogram was performed that showed a small bile leak from the choledochojejunostomy site. He was managed conservatively, and no further leakage was identified on a repeat T-tube cholangiognam 7 days later. He was discharged, and the T tube was removed after 6 weeks. Seven months later he experienced the onset of sharp constant right upper quadrant pain, nausea, and vomiting. He was seen in the emergency room with a fever of 1 02#{176}F, mild jaundice, and liver function tests significant for a bilirubin of 5.2 mg/dl, an AST (aspartate aminotransferase) of 1 94 IU per liter, an ALT (alanine aminotransferase) of 323 lU per liter, and an alkaline phosphatase of 1 61 IU per liter. A WBC count was normal. He was admitted to the hospital and placed on IV fluids, ampicillin, gentamicin, and metronidazole. The next morning a night upper quadrant sonogram showed mildly dilated intrahepatic ducts. A tnanshepatic cholangiogram and biliany drainage were performed. Contrast injection outlined a stricture at the choledochojejunal anastomotic site and mild intrahepatic duct dilatation (Fig. 1). A percutaneous biliary drainage was attempted; the stricture could not be passed, despite multiple attempts with guidewires, and so temporary external drainage was provided with a 7-French pigtail catheter.

Abstract: The purpose of this study was to develop an algorithm using CT and chemical-shift MR imaging for the characterization of adrenal masses in patients with a primary cancer and no other evidence of metastatic disease.Thirty-three patients with 37 adrenal masses (19 metastases, 18 adenomas), all of whom had a known primary cancer, were studied with noncontrast CT and chemical-shift MR imaging (1.5 T). Lesion size and density in Hounsfield units (H) were determined by CT. Adrenal signal intensity normalized to that of spleen was used to calculate adrenal-spleen ratio (ASR), defined as the percentage of signal remaining in the opposed-phase image relative to the in-phase image. Lesions less than or equal to 0 H were classified as benign, lesions greater than 20 H were regarded as malignant, and lesions between 0 and 20 H were regarded as indeterminate. Diagnoses were confirmed by biopsy (for 19 lesions) or by follow-up imaging (for 18 lesions). An imaging algorithm was derived by determining the relative value of CT and MR imaging for diagnosing the lesions. The reimbursement rates for CT-guided biopsy and MR imaging of the abdomen were obtained from Medicare.All 13 lesions of 0 or less H were correctly classified as benign by CT. ASR was less than 70 in 10 of these 13. In another 13 lesions, H was greater than 20; all were malignant and all had an ASR greater than 80. Of 11 CT-indeterminate lesions, four of five adenomas had an ASR less than 70, and four of six metastases had an ASR greater than 80. Two malignant lesions had ASRs between 70 and 80 and were diagnosed by biopsy findings. One CT-indeterminate adenoma had an ASR of 84 and was diagnosed by biopsy findings. The reimbursement rate by Medicare is similar for CT-guided biopsy with pathologic interpretation and for MR imaging of the abdomen.An algorithm was developed for diagnosis of adrenal lesions that uses the density reading on noncontrast CT as the first step, with chemical-shift MR imaging for CT-indeterminate lesions. In this algorithm, lesions of 0 H or less may be regarded as benign and further work-up is not required. Lesions with a density greater than 20 H are likely malignant and should be biopsied when the result will influence management. For CT-indeterminate lesions, we recommend chemical-shift MR imaging. An ASR threshold of 70 indicates a benign lesion, and no further workup is required in these patients. Lesions with an ASR greater than 70 should have a biopsy performed, depending on the clinical situation. The above algorithm is cost-effective and reduces the number of biopsies required without reducing the sensitivity of detecting malignant lesions.

Abstract: Densities were measured for mixtures of m-cresol + m-xylene and m-cresol + tetralin (1,2,3,4-tetrahydronaphthalene) at temperatures of 298.15, 323.15, and 348.15 K and pressures up to 30 MPa over the entire composition range. The Tait model was capable of correlating the density data accurately. Isothermal compressibilities of the fluids and their mixtures were calculated. It was also found that the excess volumes of m-cresol + m-xylene are negative and those of m-cresol + tetralin are positive over the investigated conditions.

Abstract: The purpose of this study was to compare the safety and efficacy of transpleural and extrapleural approaches for draining left subphrenic abscesses in patients who have had splenectomy.Twenty-five patients who had percutaneous catheter drainage (28 drainages) of postsplenectomy fluid collections were studied. Twenty drainages were transpleural and eight were extrapleural. In eight of the 20 transpleural drainages, it was elected to place the catheter transpleurally. In the remaining 12 patients, catheter drainage was judged to be transpleural on review, despite efforts to use an extrapleural approach.Sixteen of 18 patients who had transpleural percutaneous drainage and six of seven patients who had true extrapleural (subcostal) percutaneous drainage were cured by catheter drainage requiring no further intervention. The mean number of days of drainage was not significantly different (p.05) for the group drained transpleurally (mean, 18 days; range, 1-90 days) versus the group drained extrapleurally (mean, 20 days; range, 6-43 days). Complications (pneumothorax) requiring treatment were seen in two patients in whom a transpleural approach was used and in none of the patients in whom an extrapleural approach was used. Complications that did not require treatment were seen in four further patients drained transpleurally. These were inadvertent placement of catheter into pleural space (two patients) and pneumothorax not requiring treatment (two patients). No patient had an empyema.Transpleural drainage of left subphrenic collections occurring after splenectomy is associated with a slightly increased complication rate but has a success rate similar to that of extrapleural drainage.

Abstract: A static apparatus was installed for measuring isothermal vapor-liquid equilibrium (VLE) data for the binary and ternary mixtures composed of ethanol, acetone, and diisopropyl ether in a temperature range of 343–363 K. Maximum pressure azeotropes appeared in the binary systems containing diisopropyl ether. All the binary data passed the point, area, and infinite dilution thermodynamic consistency tests. Furthermore, the Wilson, NRTL and UNIQUAC models correlated the binary data well. The UNIQUAC model yielded the best prediction for the ternary system.

Abstract: The purposes of this study were to evaluate the ability of chemical shift MR imaging to differentiate 1- to 5-cm adrenal adenomas from metastases and to compare subjective interpretation with several different quantitative measures.Forty-three patients with 46 proved adrenal lesions (28 adenomas and 18 metastases) had MR imaging with a gradient-echo breath-hold technique and echo time varied to obtain in-phase and out-of-phase images. Qualitative analysis of the MR images was done by three experienced observers, who reported their confidence in diagnosing the benignity versus the malignancy of the adrenal masses on the basis of signal loss on out-of-phase images. Quantitative analysis was performed by calculating the difference in signal intensity between in-phase and out-of-phase images by use of regions of interest (signal intensity index) and by use of adrenal-liver, adrenal-spleen, and adrenal-muscle signal intensity ratios. Results between quantitative and qualitative measures were compared by use of receiver operating characteristic (ROC) analysis.The mean signal intensity was significantly different between adenomas and metastases on out-of-phase images (64 versus 98) (p.0005) but not in-phase images (130 versus 122) (p = .47). The adrenal-spleen ratio discriminated between adenomas and metastases better than did the adrenal-liver ratio, the adrenal-muscle ratio, or the signal intensity index. No significant difference in interpretation among the three observers was evident (areas under the ROC curves, 0.93, 0.95, and 0.96). The performance of the observers was comparable to the results obtained with the adrenal-spleen ratio measurement (area under the ROC curve, 0.97).Experienced observers were able to differentiate adrenal adenomas from metastases just as well as quantitative measures. The adrenal-spleen ratio is the best quantitative means of distinguishing benign from malignant adrenal masses. Chemical shift MR imaging is a good but imperfect discriminator of adrenal adenomas.
