Nonalcoholic fatty pancreas disease.

BACKGROUND Obesity leads to fat infiltration of multiple organs including the heart, kidneys, and liver. Under conditions of oxidative stress, fat-derived cytokines are released locally and result in an inflammatory process and organ dysfunction. In the liver, fat infiltration has been termed nonalcoholic fatty liver disease, which may lead to nonalcoholic steatohepatitis. No data are available, however, on the influence of obesity on pancreatic fat and cytokines, and nonalcoholic fatty pancreas disease (NAFPD) has not been described. Therefore, we designed a study to determine whether obesity is associated with increased pancreatic fat and cytokines. MATERIALS AND METHODS Thirty C57BL/6J lean control and 30 leptin-deficient obese female mice were fed a 15% fat diet for 4 weeks. At 12 weeks of age all animals underwent total pancreatectomy. Pancreata from each strain were pooled for measurement of a) wet and dry weight, b) histologic presence of fat, c) triglycerides, free fatty acids (FFAs), cholesterol, phospholipids, and total fat, and d) interleukin (IL)-1beta and tumor necrosis factor-alpha (TNF-alpha). Data were analyzed by Student's t test and Fisher's exact test. RESULTS Pancreata from obese mice were heavier (p<0.05) and had more fat histologically (p<0.05). Pancreata from obese mice had more triglycerides, FFAs, cholesterol, and total fat (p<0.05). Triglycerides represented 11% of pancreatic fat in lean mice compared with 67% of pancreatic fat in obese mice (p<0.01). Cytokines IL-1beta and TNF-alpha also were elevated in the pancreata of obese mice (p<0.05). CONCLUSIONS These data suggest that obese mice have 1) heavier pancreata, 2) more pancreatic fat, especially triglycerides and FFAs, and 3) increased cytokines. We conclude that obesity leads to nonalcoholic fatty pancreatic disease.
The Influence of Gender in the Familial Association Between ADHD and Major Depression

This study estimated the impact of gender on the familial associations between attention-deficit/hyperactivity disorder (ADHD) and major depression (MD). The risk for ADHD and MD in first degree relatives was stratified by the presence of MD in boy and girl ADHD probands. In families ascertained via boy probands, the risk for MD was greater in the relatives of both the depressed ADHD and nondepressed ADHD probands. In families ascertained via girl probands, there was cosegregation and the risk of MD was greater only for those relatives of depressed ADHD probands. The results indicate that there may be two mechanisms underlying MD in ADHD families: 1) an etiologically distinct familial subtype of ADHD and MD that is more evident in females, and 2) a familial, gender-specific susceptibility to nonfamilial risk factors that mediate the onset of either ADHD or MD in males and females.
Positive association between plasma IGF1 and high-density lipoprotein cholesterol levels in adult nondiabetic subjects.

AIMS Low IGF1 levels have been associated with an increased cardiovascular risk. It is unknown however whether IGF1 mediates the atherosclerotic process by modulating high-density lipoprotein cholesterol (HDL-C) independently from confounders. To address this issue, we evaluated the association between IGF1 levels and HDL-C in nondiabetic subjects. METHODS A cross-sectional analysis was used in the context of the CAtanzaro MEtabolic RIsk factors Study. One thousand and four participants (aged 20-69 years), for whom HDL-C and IGF1 measurements were available, were eligible for the study. RESULTS After adjusting for gender and age, IGF1 levels were positively correlated with HDL-C, and negatively correlated with body mass index (BMI), waist circumference, blood pressure (BP), triglyceride, fasting insulin, and homeostasis model assessment (HOMA). In a logistic regression model adjusted for age and gender, IGF1 in the lowest tertile (<125 ng/ml) was associated with an increased risk of having low HDL-C (odds ratio (OR) 2.14, 95% confidence interval (CI) 1.4-3.0; P=4x10(-5)) compared with the highest tertile (>186 ng/ml). When BMI, waist circumference, total cholesterol, triglyceride, and HOMA index were added to the model, IGF1 remained significantly associated with increased risk of low HDL-C (OR 1.52, 95% CI 1.01-2.31; P=0.04). A stepwise multivariate regression analysis in a model including age, gender, BMI, total cholesterol, triglycerides, IGF1, HOMA, and BP showed that the variables significantly associated with HDL-C were gender (P<0.0001), triglycerides (P<0.0001), total cholesterol (P<0.0001), BMI (P<0.0001), IGF1 levels (P<0.0001), and HOMA (P=0.001), accounting for 32.6% of its variation. CONCLUSIONS These data provide evidence that IGF1 may be an independent modulator for HDL-C in nondiabetic individuals.
Body composition and physical fitness of female volleyball and basketball players of the Japan inter-high school championship teams.

This study evaluated the body composition (underwater weighing) and cardiorespiratory function (VO(2)max and O(2)debt max measured by the treadmill exercise test) in 12 members of the women's volleyball team (mean age 17.4 years) and 11 members of the women's basketball team (mean age 17.6 years) that won the championship in the Japan Inter-high School Meeting. We also examined differences in the physical abilities between the members of the top teams of different events. The following results were obtained. (1) The mean values of the height and body weight were 168.7+/-5.89 cm and 59.7+/-5.73 kg in the volleyball players and 166.5+/-7.87 cm and 58.8+/-6.85 kg in the basketball players. (2) The mean %Fat was 18.4+/-3.29% in the volleyball players and 15.7+/-5.05% in the basketball players, and was similar to the reported values in elite adult players. (3) The mean VO(2)max was 2.78+/-0.32 L x min(-1) (46.5+/-2.90 ml x kg(-1) x min(-1)) in the volleyball players and 3.32+/-0.31 L x min(-1) (56.7+/-4.17 ml x kg(-1) x min(-1)) in the basketball players, and was similar to the reported values in elite adult players. (4) The mean O(2)debt max was 6.18+/-1.15 L (103.2+/-12.40 ml x kg(-1)) in the volleyball players and 7.92+/-1.80 L (134.3+/-23.24 ml x kg(-1)) in the basketball players. These values were 2.6 times and 3.3 times as high as the average values in high school students in general. (5) No significant difference was observed in any measured item of the physique, skinfold thickness, or body composition between the volleyball players and basketball players. (6) The VO(2)max and O(2)debt max were 22% and 28% higher in the basketball players than in the volleyball players. From these results, the female volleyball players and basketball players evaluated in this study had the physical abilities needed to win the championship in the Japan Inter-high School Meets, i.e. a large FFM and excellent aerobic and anaerobic work capacities. Also, basketball appears to require higher aerobic and anaerobic work capacities than volleyball.
Subcutaneous panniculitic T‐cell lymphoma and cytophagic histiocytic panniculitis

A 43‐year‐old Maori man presented with a 1 month history of malaise, weight loss, anorexia, arthralgia, recurrent fever and tender erythematous subcutaneous skin lesions. Histological examination of an incisional biopsy of a lesion revealed a lobular panniculitis with an inflammatory infiltrate of atypical lymphocytes and evidence of cytophagocytosis consistent with a diagnosis of subcutaneous T‐cell lymphoma. The systemic symptoms and skin lesions resolved spontaneously within 3 weeks, only to recur 2 months later, requiring treatment with oral prednisolone. T‐cell gene rearrangement studies demonstrated a monoclonal T‐cell receptor (γ‐chain) gene rearrangement, further supporting the diagnosis of subcutaneous panniculitic T‐cell lymphoma. Treatment with chemotherapy (cyclophosphamide, doxorubicin, vincristine and prednisone) led to remission of symptoms. Four months after completing chemotherapy, the patient remained asymptomatic with a few indurated subcutaneous plaques on the chest. Biopsy of these areas revealed lobular panniculitis, lymphocytic infiltrate without cytological atypia, abundant lipophages and fibrosis and sclerosis consistent with a healing response. He remains well 24 months following chemotherapy.

Effectiveness of the Surgical Safety Checklist in a High Standard Care Environment

Background:Use of surgical safety checklists has been associated with significant reduction in postoperative surgical site infection (SSI), morbidity, and mortality. Objective:To evaluate the effectiveness of an intraoperative checklist in high-risk surgical patients in a high standard care environment with long-standing regular perioperative safety control programs. Research Design:Quasi-experiment pre-post checklist implementation. Subjects:Surgical patients above 16 years with an American Society of Anesthesiologists (ASA) score 3–5 operated upon at a large tertiary hospital. Measures:Unplanned return to operating room for any reason, reoperation for SSI, unplanned admission to intensive care unit, and in-hospital death within 30 days. Results:A total of 609 patients (53% elective, 85% ASA 3, mean age 70 y) were included before and 1818 after implementation (52% elective, 87% ASA 3, mean age 69 y), the latter with 552, 558, and 708 in period I, II, and III, respectively. Comparing preimplementation to postimplementation periods: unplanned return to operating room occurred in 45/609 (7.4%) versus 109/1818 (6.0%) interventions [adjusted risk ratios (RR) 0.82; 95% confidence interval (CI), 0.59–1.14]; reoperation for SSI in 18/609 (3.0%) versus 109/1818 (1.7%) interventions (adjusted RR 0.56; 95% CI, 0.32–1.00); unplanned admission to intensive care unit in 17 (2.8%) versus 48 (2.6%) interventions (adjusted RR 0.90; 95% CI, 0.52–1.55); and in-hospital death occurred in 26 (4.3%) versus 108 (5.9%) patients (adjusted RR 1.44; 95% CI, 0.97–2.14). Checklist use during 77 interventions prevented 1 reoperation for SSI. Conclusions:A trend toward reduced reoperation rates for SSI was observed after checklist implementation in this high standard care environment; no influence on other outcome measures was observed.
SURVEILLANCE COLONOSCOPY USING A TRANSPARENT HOOD AND IMAGE‐ENHANCED ENDOSCOPY

Colonoscopists can miss adenomas during colonoscopy screening. A transparent hood attached to the tip of the colonoscope helps detection of colorectal adenomas, but as far as we are aware, there has been no trial indicating its statistically significant effectiveness. Total colonic dye spray might improve the adenoma detection rate but it is complicated and time‐consuming for routine clinical usage. Moreover, the efficacy of narrow band imaging for detection of colorectal adenoma is controversial and is still under debate. Autofluorescence imaging (AFI) might be better able to detect flat lesions than white light imaging (WLI), but its ability is influenced easily by the area of the observation. Therefore, we have attached a transparent hood to the tip of an AFI colonoscope during colonoscopy screening in clinical usage. AFI can detect a flat lesion, which is difficult to detect using WLI. A transparent hood can help to detect lesions behind the folds by pushing the colonic fold. We expect that mounting a transparent hood would work complimentary to AFI. Further improvements, including a combination of AFI and a transparent hood, are needed and they would provide optimal surveillance intervals.
Anti-Insulin Antibodies in Insulin Immunometric Assays: A Still Possible Pitfall

Insulin was assayed directly using radioimmunoassay and immunometric assay in 31 sera containing anti-insulin antibodies. Anti-insulin antibodies were determined by radio-binding-assay. Insulin measurements were compared with those of free (unbound to antibodies, polyethylene glycol precipitated) insulin measurements. Compared with free insulin concentrations, radioimmunoassay and immunometric assay yielded falsely increased insulin results. The degree of overestimation by radioimmunoassay and by immunometric assay correlated with the anti-insulin antibody value. Anti-insulin antibodies still remain a possible pitfall in the insulin-specific immunometric assays which are now being widely used.
Evaluation of new rapid commercial enzyme immunoassay for detection of Cryptosporidium oocysts in untreated stool specimens

Sixty-six stool specimens were evaluated by the ProSpecTR Cryptosporidium rapid enzyme immunoassay (EIA) (Alexon, Sunnyvale, Calif.). Approximately 2 g of untreated stool suspended in buffer was filtered through membranes labelled with anti-Cryptosporidium-specific antigen antibody. Anti-Cryptosporidium-specific antigen antibody was labelled with biotin, horseradish peroxidase conjugated to streptavidin, and tetramethylbenzidine, and each labelled antibody was added in sequence to the membranes. Each membrane had a positive control and test area. EIA results were compared with those of the modified acid-fast procedure. Twenty-three specimens were positive by the initial acid-fast procedure and the EIA. Forty-two specimens were negative by the initial acid-fast test and the EIA. One specimen was negative by the initial acid-fast test and positive by the EIA (sensitivity, 100%; specificity, 98.5%). This technique is easy to use by comparison with the cumbersome, labor-intensive, and more subjective microscopic methods currently available, and its sensitivity equals that of current microscopic methods.
Functional characteristics of two human MATE transporters: kinetics of cimetidine transport and profiles of inhibition by various compounds.

PURPOSE Human multidrug and toxin extrusion protein 1 (hMATE1) and hMATE2-K are organic cation/H+ antiporters that have recently been identified and suggested to be involved in the renal brush border secretion of various organic cations. Information about functional characteristics of them has been accumulating, but still insufficient to fully understand their functions and respective roles. The present study was conducted to help clarify them. METHODS The cDNA of hMATE1 was isolated from human brain cDNA by RT-PCR and hMATE2-K cDNA was from human kidney cDNA. HEK293 cells were stably transfected with hMATE1 and hMATE2-K, and the cellular uptakes of [3H]cimetidine and [14C]tetraethylammonium (TEA) were evaluated. RESULTS It was first found that both hMATE1 and hMATE2-K can transport cimetidine with high affinities, indicated by small Michaelis constants of 8.00 mM and 18.18 mM, respectively. These were much smaller than those for TEA (366 mM and 375 mM, respectively, for hMATE1 and hMATE2-K). Subsequent investigation using cimetidine as a probe substrate into the profiles of inhibition of the two hMATEs by various compounds indicated that they are similar in principle but different to some extent in substrate recognition, reflecting the modest differences in amino acid sequences between them. In fact, cimetidine transport by hMATE1 was correlated to that by hMATE2-K, which is 65% similar to hMATE1, but not as good as to that by rat MATE1, which is 86% similar. CONCLUSIONS Cimetidine was demonstrated to be a high affinity substrate of both hMATEs. Subsequent evaluation of the inhibition of hMATEs by various compounds indicated no major difference in function or role between hMATE1 and hMATE2-K.
Drought Stress, Permeability to O2 Diffusion, and the Respiratory Kinetics of Soybean Root Nodules

In legume nodules, treatments such as detopping or nitrate fertilization inhibit nodule metabolism and N2 fixation by decreasing the nodule's permeability to O2 diffusion, thereby decreasing the infected cell O2 concentration (Oi) and increasing the degree to which nodule metabolism is limited by O2 availability. In the present study we used nodule oximetry to assess and compare the role of O2 limitation in soybean (Glycine max L. Merr) nodules inhibited by either drought or detopping. Compared to detopping, drought caused only minor decreases in Oi, and when the external O2 concentration was increased to raise Oi, the infected cell respiration rate in the drought-stressed plants was not stimulated as much as it was in the nodules of the detopped plants. Unlike those in detopped plants, nodules exposed to moderate drought stress displayed an O2-sufficient respiration rate that was significantly lower than that in control nodules. Despite possible side effects of oximetry in altering nodule metabolism, these results provided direct evidence that, compared to detopping, O2 limitation plays a minor role in the inhibition of nodule metabolism during drought stress and changes in nodule permeability are the effect, not the cause, of a drought-induced inhibition of nodule metabolism and the O2-suffiecient rate of respiration.
Varieties of localization: international norms and the commodification of knowledge in India and Brazil

ABSTRACT The legal implementation of internationally agreed norms on a domestic level gives momentum to a substantial reinterpretation. Based on this insight, this article develops an ideal-typology of possible ‘localization’ outcomes. Apart from a literal adoption of an international norm, we show that the domestic implementation may change its emphasis (accentuation), amend it by supplementary purposes (addition), or imply a deviation which nevertheless sticks to the letter of the international wording (subversion). We argue that the specific form of localization depends on the interaction between international pressure politics and its congruence with the prevailing domestic public and private preferences. International power constellations explain why an international norm is implemented, but the specific character of its localization is mainly determined by domestic actor constellations. To substantiate our claims, we analyze the implementation of two interconnected international agreements in India and Brazil. While both the Convention on Biodiversity and the Agreement on Trade Related Aspects of Intellectual Property Rights introduce the norm of property rights for intellectual knowledge in previously (at least internationally) unregulated fields, the particular characteristics of their respective implementation in both countries display the interaction between international pressure and domestic preferences in our four case studies.
A new method for estimating splenic erythrocyte and plasma volume combined with quantitation of splenic iron incorporation.

A method for in vivo determination of the splenic erythrocyte and plasma volume has been developed. Ultrasonic scanning of the splenic region permits not only determination of the shape and topography of the spleen, but also calculation of its volume with great accuracy, using simultaneous computer analysis. Splenic models of a volume as determined by ultrasonic scanning were made of water-filled balloons and shaped as accurate copies of the scanned spleens. After infusion of known quantities of 51Cr-labelled erythrocytes and 125I-labelled albumin, intravenously and into a model of the patient's spleen, it may be determined – by surface measurements over the spleen in situ and over the balloon model – how large a part of the total erythrocyte and plasma volume is localized in the spleen. By the use of 59Fe, the method also allows quantitative determination of the iron incorporation in a spleen with extramedullary erythropoiesis. The percentage which the erythrocyte pool in the spleen constitutes of the total erythrocyte volume increases with increasing spleen weight, apparently independently of the underlying haematological disease.
The antitumoral effect of endostatin and angiostatin is associated with a down‐regulation of vascular endothelial growth factor expression in tumor cells

Endostatin and angiostatin are known as tumor‐derived angiogenesis inhibitors, but their mechanisms of action are not yet completely defined. We report here that endostatin and angiostatin, delivered by adenoviral vectors, reduced in vitro the neovessel formation in the mouse aortic ring assay by 85 and 40%, respectively. We also demonstrated in vivo that both endostatin and angiostatin inhibited local invasion and tumor vascularization of transplanted murine malignant keratinocytes, and reduced by 50 and 90% the development of highly vascularized murine mammary tumors. This inhibition of tumor growth was associated with a reduction of tumor vascularization. Expression analysis of vascular endothelial growth factor (VEGF) carried out in the mouse aortic ring model revealed a 3‐ to 10‐fold down‐regulation of VEGF mRNA expression in endostatin‐treated rings. A similar down‐regulation of VEGF expression at both mRNA and protein levels was also observed in the two in vivo cancer models after treatment with each angiogenesis inhibitor. This suggests that endostatin and angiostatin effects may be mediated, at least in part, by their ability to down‐regulate VEGF expression within the tumor. This work provides evidence that endostatin and angiostatin act on tumor cells themselves.
Application of BI-RADS Descriptors in Contrast-Enhanced Dual-Energy Mammography: Comparison with MRI

Background: Contrast-enhanced (CE) magnetic resonance imaging (MRI) BI-RADS descriptors are used in the evaluation of contrast-enhanced dual-energy mammography (CEDEM) images of mass lesions and are assumed to be applicable. Patients and Methods: Patients with suspicious mass lesions on mammography (BI-RADS 4 or 5) were included. CEDEM examinations were performed using a modified prototype unit. CE-MRI was performed using a high temporal and high spatial resolution imaging protocol. 2 blinded breast radiologists evaluated all images using criteria related to contrast enhancement intensity and morphology according to the BI-RADS lexicon (5th edition) in 2 sessions. Histopathology was used as the standard of reference. Results: 11 patients with 5 benign and 6 malignant index lesions were included. Enhancement characteristics were similar in the malignant cases. Enhancement of the benign lesions was moderate on CEDEM and strong on MRI. Discrepancies in the BI-RADS descriptors did not influence the final BI-RADS score. Overall, the BI-RADS assessment was almost identical in all cases. 1 malignant lesion was rated BI-RADS 4 with CEDEM and BI-RADS 5 with MRI, and 1 benign was rated BI-RADS 2 and BI-RADS 1, respectively. Conclusion: MRI BI-RADS descriptors of contrast-enhancing lesions can be applied for the morphologic analysis of mass lesions on CEDEM.
