Neural Systems for Error Monitoring

Complex behavior requires a flexible system that maintains task performance in the context of specific goals, evaluating behavioral progress, adjusting behavior as needed, and adapting to changing contingencies. Generically referred to as performance monitoring, a key component concerns the identification and correction of differences between an intended and an executed response (i.e., an error). Brain mapping experiments have now identified the temporal and spatial components of a putative error-processing system in the large-scale networks of the human brain. Most of this work has focused on the medial frontal cortex and an associated electrophysiological component known as the error-related negativity (or error negativity). Although the precise role, or roles, of this region still remain unknown, investigations of error processing have identified a cluster of modules in the medial frontal cortex involved in monitoring/maintaining ongoing behavior and motivating task sets. Other regions include bilateral anterior insula/inferior operculum and lateral prefrontal cortex. Recent work has begun to uncover how individual differences might affect the modules recruited for a task, in addition to the identification of associations between pathological states and aberrant error signals, leading to insights about possible mechanisms of neuropsychiatric illness.

Open surgery, laparoscopic surgery, or transureteral lithotripsy--which method? Comparison of ureteral stone management outcomes.

BACKGROUND AND PURPOSE The optimal treatment option for ureteral calculi is a controversial issue. In this study, we present our experience of 60 patients, divided into three groups, who were treated using open surgery, laparoscopic surgery, or transureteral lithotripsy (TUL). PATIENTS AND METHODS We enrolled 60 patients who had upper ureteral calculi >l0 mm in diameter from June 2008 to August 2009 in our center. In a prospective study, preoperative and postoperative data were evaluated, and for statistical analyses, the chi-square test, one-way analysis of variance, and post hoc test were used. RESULTS The mean operative time was 70, 191, and 162.5 minutes in the TUL, laparoscopic, and open groups, respectively. The mean hospital stay was 1.65, 4.2, and 4.35 days in the three groups, respectively. The stone-free rate was 90%, 95%, and 100% in the three groups, respectively. Flank pain was reported as 15%, 5%, and 15%, in the three groups, respectively. Hemoglobin decrease necessitating blood transfusion was not reported in the TUL and laparoscopic groups, but blood transfusion was reported in 15% in the open group. The lowest dose of analgesic was used in the TUL group. There was no damage to the ureter and adjacent organs and wound infection in the three groups. CONCLUSION Our study showed that the complications after laparoscopic surgery were lower than in open surgery. We recommend laparoscopic surgery for upper ureteral stones >1 cm because of lower postoperative complications, shorter hospital stay, and shorter time to convalescence, and better cosmetic results.
Changes in lipoprotein kinetics associated with type 2 diabetes affect the distribution of lipopolysaccharides among lipoproteins.

CONTEXT Lipopolysaccharides (LPSs) are inflammatory components of the outer membrane of Gram-negative bacteria and, in plasma, are mostly associated with lipoproteins. This association is thought to promote their catabolism while reducing their proinflammatory effects. OBJECTIVES Our aim was to determine the impact of lipoprotein kinetics on plasma LPS distribution and how it may affect patients with type 2 diabetes mellitus (T2DM). DESIGN We performed a kinetic study in 30 individuals (16 T2DM patients, 14 controls) and analyzed the impact of changes in lipoprotein kinetics on LPS distribution among lipoproteins. RESULTS Plasma LPS levels in T2DM patients were not different from those in controls, but LPS distribution in the two groups was different. Patients with T2DM had higher LPS-very low-density lipoprotein (VLDL; 31% ± 7% vs 22% ± 11%, P = .002), LPS-high-density lipoprotein (HDL; 29% ± 9% vs 19% ± 10%, P = .015), free (nonlipoprotein bound) LPS (10% ± 4% vs 7% ± 4%, P = .043) and lower LPS-low-density lipoprotein (LDL; 30% ± 13% vs 52% ± 16%, P = .001). In multivariable analysis, VLDL-LPS was associated with HDL-LPS (P < .0001); LDL-LPS was associated with VLDL-LPS (P = .004), and VLDL apolipoprotein (apo) B100 catabolism (P = .002); HDL-LPS was associated with free LPS (P < .0001) and VLDL-LPS (P = .033); free LPS was associated with HDL-LPS (P < .0001). In a patient featuring a dramatic decrease in VLDL catabolism due to apoA-V mutation, LDL-LPS was severely decreased (0.044 EU/mL vs 0.788 EU/mL in controls). The difference between T2DM patients and controls for LDL-LPS fraction was no longer significant after controlling for VLDL apoB100 total fractional catabolic rate. CONCLUSIONS Our data suggest that in humans, free LPS transfers first to HDL and then to VLDL, whereas the LPS-bound LDL fraction is mainly derived from VLDL catabolism; the latter may hence represent a LPS catabolic pathway. T2DM patients show lower LDL-LPS secondary to reduced VLDL catabolism, which may represent an impaired catabolic pathway.
Ameliorative effects of curcumin against lead induced toxicity in human peripheral blood lymphocytes culture

Abstract Lead, a heavy metal and multifaceted toxicant, is well studied for its distribution and toxicity in ecosystem, yet there is no consensus on its amelioration by any synthetic or phytochemical compounds. Curcumin, a known antioxidant and dietary element, is a well-known herb, for its therapeutic uses and having a wide spectrum of its beneficial properties against several adverse effects. Hence, the current study was taken into consideration to evaluate the ameliorative effects of curcumin (3.87 μM, i.e. 1.43 μg/ml) against lead acetate (doses: 10−6 M, i.e. 0.379 μg/ml and 10−4 M, i.e. 37.9 μg/ml, durations: 24 h and 69 h) induced genotoxicity and oxidative stress in human peripheral blood lymphocyte cultures (PBLC). On one hand, antigenotoxic and antioxidative potentials of curcumin against lead were simultaneously evaluated by the array of genotoxicity and oxidative stress indices. The result postulated that lead acetate showed dose- and duration-dependent increase in both genotoxicity and oxidative stress whereas curcumin, when added along with lead acetate, showed the significant amelioration in all genotoxic and oxidative stress-related indices. The study indicated that, due to alteration in antioxidant defense system, there is an adverse genotoxic effect of lead. On the other hand, curcumin, a potent antidote, can protect chromatin material against lead -mediated genotoxicity by balancing the activity of antioxidant defense system.
Langmuir–Blodgett monolayers of colloidal lead chalcogenide quantum dots: morphology and photoluminescence

Monolayers of PbSe and PbS quantum dots and PbSe/CdSe core/shell quantum dots made by Langmuir–Blodgett deposition are compared, with a focus on the formation, the morphology and the photoluminescence properties of the films. It is shown that PbSe quantum dots suffer from oriented attachment and a complete quenching of their photoluminescence after Langmuir–Blodgett processing. While the oriented attachment can be resolved by growing a CdSe shell around the PbSe core QDs, the photoluminescence of PbSe/CdSe Langmuir–Blodgett monolayers remains largely quenched. In the case of PbS quantum dots, the formation of a close-packed monolayer is more difficult, yet the resulting films show no sign of oriented attachment and their photoluminescence is comparable to that of the original, suspended quantum dots. In spite of their slow oxidation in a matter of weeks, these results mark PbS quantum dots as the preferred material for light-emitting applications in the near IR based on Langmuir–Blodgett monolayers of lead chalcogenide quantum dots.
Relation between birthweight and blood pressure among 7-8 year old rural children in India.

BACKGROUND Fetal malnutrition has been proposed as a cause of higher blood pressure. However, some studies have shown no or little effect of birthweight on blood pressure. Confounding and selection bias have been a problem in some of the studies. The ideal approach for avoiding selection bias is to conduct a prospective cohort study with minimal loss during follow-up. Therefore, the relationship of birthweight with blood pressure was examined in a cohort born during 1992-1993. METHODS A cohort of 214 babies, born to usual residents in 10 villages of Haryana state in India on weekdays from September 1992 to November 1993 whose birthweight had been recorded by a trained field worker within 24 hours of delivery, were followed up during 2000-2001. During the 7-8 year period, 17 children had died and 12 had migrated. A trained public health nurse examined the remaining 185 children and measured their weight, height, and blood pressure. RESULTS Mean birthweight was 2.7 kg and 21.1% had low birthweight (<2500 g). Current weight, height, and body mass index (BMI) were associated with birthweight (P < 0.05). Systolic blood pressure (SBP) increased significantly with rise in current weight and height. Relationship of SBP with birthweight seems to be a U-shaped distribution. Compared with the middle birthweight tertile group, in the lowest and highest birthweight groups boys have higher SBP in the higher BMI category (>or=13.5 kg/m(2)) and girls have higher SBP in both lower and higher BMI categories. ANOVA analysis showed that SBP and diastolic blood pressure (DBP) were not significantly different in birthweight tertile groups among boys, but for SBP the difference was statistically significant among girls (P = 0.03). However, multivariate linear regression analysis that included socioeconomic status and current anthropometeric measures (weight, height, BMI) revealed that birthweight is not associated with SBP or DBP, and the interaction between birthweight and gender was also not significant for SBP and DBP (P = 0.09). CONCLUSION The findings of this population-representative cohort from rural India with 94% follow-up suggest that birthweight is not associated with blood pressure among 7-8 year old children.
Comparison of Bioactivity Between GSM 900 MHz and DCS 1800 MHz Mobile Telephony Radiation

An increasing number of studies find that pulsed Radio Frequency (RF), electromagnetic radiation of both systems of digital mobile telephony, established and commonly used in Europe during the last years, GSM 900 MHz (Global System for Mobile telecommunications) and DCS 1800 MHz (Digital Cellular System), exert intense biological action on different organisms and cells (Hardell et al., 19; Hyland, 23; Kundi, 26; Panagopoulos et al., 4445). The two types of cellular telephony radiation use different carrier frequencies and give different frequency spectra, but they usually also differ in intensity, as GSM 900 MHz antennas operate at about double the power output than the corresponding DCS 1800 MHz ones. In our present experiments, we used a model biological system, the reproductive capacity of Drosophila melanogaster, to compare the biological activity between the two systems of cellular mobile telephony radiation. Both types of radiation were found to decrease significantly and non thermally the insect's reproductive capacity, but GSM 900 MHz seems to be even more bioactive than DCS 1800 MHz. The difference seems to be dependent mostly on field intensity and less on carrier frequency.
Studies on Indigenous Ceremony Values in Strengthening the Character of the Nation

Globalization results in a shift in socio-cultural values that cause a crisis of a nation’s identity and impact on the degradation of the character of its citizens. The values of the nation’s identity can be obtained through local wisdom in the Traditional Ceremony which contains good values and is believed by the community so that it becomes a guide in behaving. Therefore, society can adapt to globalization without leaving tradition. The research method used is a case study method with a qualitative approach, to understand and explain various problems in depth. Data collection is done through documentation, observation, and interviews. The research site of this study was the scope of Mekarsari Village, Bandung Regency, West Java Province, Indonesia. Meanwhile, the subjects of research are a custodian (Juru Kunci), village officials, and local public figures. The results showed that the Traditional Ceremony process contained values in the preparation and implementation stages, especially religious and social values, then, in the stage of equipment used contained symbols that showed the character values of the nation. Maintaining this traditional ceremony is done by embracing the younger generation to know, to understand and to implement it. The aim is none other than the traditional ceremony as Sundanese local wisdom can be sustainable and its existence which also receives real support from the government makes the traditional ceremony a part of efforts to strengthen the character of the nation. Keywords—local wisdom; nation’s character; traditional ceremony
Adaptation and Validation of a Nutrition Environment Measures Survey for University Grab-and-Go Establishments.

PURPOSE To adapt and validate a survey instrument to assess the nutrition environment of grab-and-go establishments at a university campus. METHODS A version of the Nutrition Environment Measures Survey for grab-and-go establishments (NEMS-GG) was adapted from existing NEMS instruments and tested for reliability and validity through a cross-sectional assessment of the grab-and-go establishments at the University of Toronto. Product availability, price, and presence of nutrition information were evaluated. Cohen's kappa coefficient and intra-class correlation coefficients (ICC) were assessed for inter-rater reliability, and construct validity was assessed using the known-groups comparison method (via store scores). RESULTS Fifteen grab-and-go establishments were assessed. Inter-rater reliability was high with an almost perfect agreement for availability (mean κ = 0.995) and store scores (ICC = 0.999). The tool demonstrated good face and construct validity. About half of the venues carried fruit and vegetables (46.7% and 53.3%, respectively). Regular and healthier entrée items were generally the same price. Healthier grains were cheaper than regular options. Six establishments displayed nutrition information. Establishments operated by the university's Food Services consistently scored the highest across all food premise types for nutrition signage, availability, and cost of healthier options. CONCLUSIONS Health promotion strategies are needed to address availability and variety of healthier grab-and-go options in university settings.

[Reversal effect of mifepristone on adriamycin resistance in human breast cancer cell line MCF-7/ADM in vitro and in vivo].

OBJECTIVE To explore the reversal effect of mifepristone(MIF) on adriamycin(ADM) resistance in human breast cell line MCF-7/ADM in vitro and in vivo. METHODS The transplantable models of MCF-7 cells resisting against adriamycin were established in nude mice by subcutaneous implantation to observe the reversal effect of MIF in vivo. The mice were randomly divided into 4 groups: a control group(treated with saline water 0.2 mL intraperitoneally and edible oil 0.5 mL orally), an MIF group (treated with mifepristone 30 mg/kg orally and saline water 0.2 mL intraperitoneally), an ADM group (treated with adriamycin 5 mg/kg intraperitoneally and edible oil 0.5 mL orally) and an ADM+MIF group (treated with ADM 5mg/kg intraperitoneally and mifepristone 30 mg/kg orally every 3 days). Tumor changes were investigated after different drug treatments. The reversal effect of 5 micromol/L MIF in vitro on the ADM resistance cell line MCF-7/ADM and non ADM resistance cell line MCF-7 was determined by 4,5-dimethylthiazol-2-yl (MTT) assay. RESULTS (1) The inhibitory rate of 5 micromol/L of MIF for both cell lines MCF-7 and MCF-7/ADM was less than 5%, and it had no statistical difference compared with the group that was not treated with MIF(P > 0.05). (2) ADM could inhibit the growth of both MCF-7 and MCF-7/ADM,but the inhibition concentration 50 (IC(50)) of MCF-7 (0.42 mg/L) was obviously less than that of MCF-7/ADM(17.21 mg/L) (P < 0.05). (3) IC(50) of MCF-7/ADM of MIF+ADM group was 1.96 mg/L in vitro, which was significantly less than that in ADM alone group(17.21 mg/L) (P < 0.05), and 5 micromol/L of MIF reversed ADM resistance with fold-reversal of 8.78. (4) MIF had some effect on the inhibition of MCF-7/ADM cell growth in vivo, the xenograft volume in the MIF+ADM group [(232.5149 +/- 309.2377) mm(3)] was significantly smaller than that in the control group[(962.2309 +/- 261.1313) mm(3) ] after the 4 week treatment(P<0.05), and also smaller than that in the MIF group [(778.2846 +/- 42.6919) mm(3)] and in the ADM group [(508.9648 +/- 16.2609) mm(3)](P < 0.05). There was significant inhibition on xenograft weight after MIF combined with ADM treatment in vivo, and the inhibitory rate was 78.0%. CONCLUSION MIF can effectively reverse ADM resistance in human breast cancer cell line MCF-7/ADM both in vitro and in vivo.
A Novel Anti-Inflammatory Role of Simvastatin in a Murine Model of Allergic Asthma1

Statins, the 3-hydroxy-3-methylglutaryl-CoA reductase inhibitors, are effective serum cholesterol-lowering agents in clinical practice, and they may also have anti-inflammatory properties. Asthma is characterized by chronic eosinophilic inflammation in the airways, which is thought to be regulated by the activity of T lymphocytes. We therefore examined the anti-inflammatory activity of simvastatin in a murine model of allergic asthma. In mice previously sensitized to OVA, simvastatin treatment, either orally or i.p., reduced the total inflammatory cell infiltrate and eosinophilia in bronchoalveolar lavage fluid in response to inhaled OVA challenge. Simvastatin therapy i.p. was also associated with a reduction in IL-4 and IL-5 levels in bronchoalveolar lavage fluid and, at higher doses, a histological reduction in inflammatory infiltrates in the lungs. OVA-induced IL-4, IL-5, IL-6, and IFN-γ secretion was reduced in thoracic lymph node cultures from simvastatin-treated mice. Simvastatin treatment did not alter serum total IgE or OVA-specific IgG1 and IgG2a levels. These data demonstrate the therapeutic potential of statin-sensitive pathways in allergic airways disease.
Ceramide 1-Phosphate Mediates Endothelial Cell Invasion via the Annexin a2-p11 Heterotetrameric Protein Complex*

Background: Extracellular ceramide 1-phosphate is presumed to interact with extracellular proteins to mediate cellular invasion. These proteins are unidentified. Results: C-1-P interacts with both annexin a2 and p11 proteins. C-1-P-mediated vascular endothelial cell invasion requires expression of these proteins. Conclusion: Extracellular C-1-P mediates invasion via an interaction with the annexin a2-p11 heterotetramer. Significance: Gradients of C-1-P may guide vascular endothelial cell invasion during wound healing. The bioactive sphingolipid, ceramide 1-phosphate (C-1-P), has been implicated as an extracellular chemotactic agent directing cellular migration in hematopoietic stem/progenitor cells and macrophages. However, interacting proteins that could mediate these actions of C-1-P have, thus far, eluded identification. We have now identified and characterized interactions between ceramide 1-phosphate and the annexin a2-p11 heterotetramer constituents. This C-1-P-receptor complex is capable of facilitating cellular invasion. Herein, we demonstrate in both coronary artery macrovascular endothelial cells and retinal microvascular endothelial cells that C-1-P induces invasion through an extracellular matrix barrier. By employing surface plasmon resonance, lipid-binding ELISA, and mass spectrometry technologies, we have demonstrated that the heterotetramer constituents bind to C-1-P. Although the annexin a2-p11 heterotetramer constituents do not bind the lipid C-1-P exclusively, other structurally similar lipids, such as phosphatidylserine, sphingosine 1-phosphate, and phosphatidic acid, could not elicit the potent chemotactic stimulation observed with C-1-P. Further, we show that siRNA-mediated knockdown of either annexin a2 or p11 protein significantly inhibits C-1-P-directed invasion, indicating that the heterotetrameric complex is required for C-1-P-mediated chemotaxis. These results imply that extracellular C-1-P, acting through the extracellular annexin a2-p11 heterotetrameric protein, can mediate vascular endothelial cell invasion.
