Emotional responses associated with self-face processing in individuals with autism spectrum disorders: An fMRI study

Individuals with autism spectrum disorders (ASD) show impaired emotional responses to self-face processing, but the underlying neural bases are unclear. Using functional magnetic resonance imaging, we investigated brain activity when 15 individuals with high-functioning ASD and 15 controls rated the photogenicity of self-face images and photographs of others' faces. Controls showed a strong correlation between photogenicity ratings and extent of embarrassment evoked by self-face images; this correlation was weaker among ASD individuals, indicating a decoupling between the cognitive evaluation of self-face images and emotional responses. Individuals with ASD demonstrated relatively low self-related activity in the posterior cingulate cortex (PCC), which was related to specific autistic traits. There were significant group differences in the modulation of activity by embarrassment ratings in the right insular (IC) and lateral orbitofrontal cortices. Task-related activity in the right IC was lower in the ASD group. The reduced activity in the right IC for self-face images was associated with weak coupling between cognitive evaluation and emotional responses to self-face images. The PCC is responsible for self-referential processing, and the IC plays a role in emotional experience. Dysfunction in these areas could contribute to the lack of self-conscious behaviors in response to self-reflection in ASD individuals.
Early relationships as regulators of infant physiology and behavior

In recent years, animal research has revealed a network of simple behavioral and biological processes that underlie the psychological constructs we use to define early social relationships. Hidden within the observable interactions of parent and offspring are sensorimotor, thermal and nutrient‐based events which have unexpected and widespread regulatory effects on infant behavior and physiology. The complex pattern of responses resulting from early separation in infant rats can be traced to the abrupt withdrawal of a number of discrete, independent regulatory processes which had been acting on individual components of the infant's physiology and behavior. These regulatory processes also appear to mediate long‐term shaping effects exerted by early relationships, for example, on the vulnerability of the adult rat to hypertension and stress ulcer. In human development, early regulatory interactions may provide a bridge between biological and psychological processes in the development of our earliest mental representations.
Daytime Multilayered Cloud Detection Using Multispectral Imager Data

Abstract This study reports on recent progress toward the daytime detection of multilayered clouds in satellite multispectral data, specifically for the case of optically thin cirrus overlying lower-level water clouds. The technique is applied to 200 × 200 pixel arrays of data from the Moderate Resolution Imaging Spectroradiometer (MODIS) and is primarily based on the relationship between the near-infrared reflectance (at either 1.6 or 2.1 μm) and the 11-μm brightness temperature. Additional information used by the algorithm includes the operational MODIS cloud mask and cloud thermodynamic phase as inferred from the 8.5- and 11-μm brightness temperatures. The performance of the algorithm is evaluated for two MODIS case studies, and results are compared to coincident cloud physics lidar (CPL) data obtained from an aircraft platform. In both cases, the multilayered cloud detection algorithm results appear reasonable in comparison with the CPL data. The first case study, from 11 December 2002 during the Terr.
A Novel 4EHP-GIGYF2 Translational Repressor Complex Is Essential for Mammalian Development

ABSTRACT The binding of the eukaryotic initiation factor 4E (eIF4E) to the mRNA 5′ cap structure is a rate-limiting step in mRNA translation initiation. eIF4E promotes ribosome recruitment to the mRNA. In Drosophila, the eIF4E homologous protein (d4EHP) forms a complex with binding partners to suppress the translation of distinct mRNAs by competing with eIF4E for binding the 5′ cap structure. This repression mechanism is essential for the asymmetric distribution of proteins and normal embryonic development in Drosophila. In contrast, the physiological role of the mammalian 4EHP (m4EHP) was not known. In this study, we have identified the Grb10-interacting GYF protein 2 (GIGYF2) and the zinc finger protein 598 (ZNF598) as components of the m4EHP complex. GIGYF2 directly interacts with m4EHP, and this interaction is required for stabilization of both proteins. Disruption of the m4EHP-GIGYF2 complex leads to increased translation and perinatal lethality in mice. We propose a model by which the m4EHP-GIGYF2 complex represses translation of a subset of mRNAs during embryonic development, as was previously reported for d4EHP.
Donor Age and Cold Ischemia Interact to Produce Inferior 90-Day Liver Allograft Survival

Background. Expanded regional sharing of liver allografts may increase cold ischemia and allograft failure, particularly with livers from older donors. The aim of this study was to examine whether older donor age and cold ischemic time interact to produce inferior allograft survival. Methods. We undertook a retrospective cohort study of adult liver transplants in the United States performed between December 1, 1995 and December 31, 2005, using data from the Organ Procurement and Transplantation Network. The primary outcome was allograft failure within 90 days. Results. Forty-four thousand seven hundred fifty-six liver transplant recipients were analyzed. Older age was defined as 45 years or more, and prolonged cold ischemia was defined as 12 hours or more. Using data from the pre-Model for End Stage Liver Disease (MELD), post-MELD and combined eras, three separate analyses of the interaction between older donor age and prolonged cold ischemia were performed. In multivariable logistic regression, the interaction of age 45 years or more and cold ischemia more than or equal to 12 hr reached statistical significance in the combined (OR 1.24, CI 1.08–1.42, P<0.01) and pre-MELD (OR 1.26, CI 1.08–1.46, P<0.01) datasets, but not in the smaller post-MELD dataset (OR 1.18, CI 0.81–1.72, P=0.38). In the combined dataset, recipients of livers from donors aged 45 years or more and cold ischemia more than or equal to 12 hr showed an adjusted absolute risk of allograft failure at 90 days of 17.3% (odds ratio 1.84), compared with 11.1% for recipients of livers from donors older than 45 years and cold ischemia less than 12 hr. Conclusions. These findings suggest that older donor age and prolonged cold ischemia interact to increase liver allograft failure at 90 days. Proposals to expand regional sharing of older livers should be regarded with caution.
A theoretical and experimental comparison of continuous and pulsed arterial spin labeling techniques for quantitative perfusion imaging

Under ideal conditions, continuous arterial spin labeling (ASL) techniques are higher in SNR than pulsed ASL techniques by a factor of e. Presented here is a direct theoretical and experimental comparison of continuous ASL and pulsed ASL, using versions of both that are amenable to multislice imaging and insensitive to variations in transit times (continuous ASL with a delay before imaging, and QUIPSS II (Quantitative Imaging of Perfusion Using a Single Subtraction–second version)). Perfusion image quality for comparable imaging time was nearly identical for both single‐slice and multislice imaging. The measured raw signal was approximately 25% higher with continuous ASL, but the SNR per unit time was identical.
Ypt protein prenylation depends on the interplay among levels of Rab escort protein and geranylgeranyl diphosphate in yeast cells

Farnesyl diphosphate (FPP), an intermediate of the sterol biosynthetic pathway, is used by farnesyl transferase to farnesylate, among others, the Ras proteins, and by geranylgeranyl diphosphate synthase to produce geranylgeranyl diphosphate (GGPP). GGPP is then transferred by geranylgeranyl transferase II (GGTase II) to Rab/Ypt members of the Ras superfamily known to be required at all stages of vesicle transport in both mammals and yeast. Formation of a complex between a Rab/Ypt protein and an accessory protein named the Rab escort protein (REP) is a prerequisite for GGTase II substrate recognition. Little is known about the factors that regulate GGTase II activity in living cells but, based on available data, it seems possible that vesicle transport in higher eukaryotes is regulated by the levels of prenylated Rab/Ypt proteins in the cells. Here we show that the levels of REP play an important role in regulating GGTase II activity in yeast cells if sufficient substrates are present. Moreover, overexpression of REP causes, directly or indirectly, an increased level of Ypt substrates available for prenylation, which in turn leads to the depletion of the GGPP pool in the cell. Overall our data suggest that the levels of REP and the availability of GGPP play a role in regulating Ypt protein prenylation. Copyright © 2001 John Wiley & Sons, Ltd.
The Impact of Mental Representations on ICT-Related Overload in the Use of Mobile Phones

Abstract The use of information and communication technology (ICT) can be accompanied by the epiphenomenon of ICT-related overload, or the emotional and cognitive state that occurs when individuals are unable to efficiently retrieve and process information delivered by or associated with these technologies. While prior research tends to ascribe this phenomenon to the amount of information delivered, this study presents and provides significant empirical support for an expanded cognitive perspective of ICT-related overload, which views individuals’ information-processing capabilities as being reliant on differences in mental representations associated with cultural, demographic, and experiential factors. Specifically, based on a survey with 1,004 mobile phone users, we find that (1) polychronic individuals experience less ICT-related overload than monochronics; (2) memories of past emotional and cognitive overload increase ICT-related overload; and (3) age has inverse effects on different overload dimensions. Altogether, our findings challenge myths about information overload and multitasking, support a multidimensional conceptualization of ICT-related overload, and suggest ways that managers can reduce overload and leverage polychronicity.
Thoraco‐abdominal asymmetry and asynchrony in congenital diaphragmatic hernia

Congenital diaphragmatic hernia (CDH) consists of an incomplete formation of the diaphragm and the subsequent herniation of abdominal bowels. Diaphragmatic defect can be repaired by primary closure or placing a patch. Respiratory follow up usually focuses on spirometric and clinical evaluation. The aim of the study was to assess thoraco‐abdominal volumes in CDH patients and to verify whether the action of the diaphragm on the chest wall is altered leading to an asymmetric and asynchronous expansion of the different thoracoabdominal compartments.
Working with Children

Chances are that each of us was infl uenced by someone who cared about the environment and cared about children. Today, many adults want to “pay back” a debt of gratitude by introducing children to the wonderful world of trees, but they are not sure how best to proceed.

Cation Transport in Intact Erythrocytes of Hyperthyroid Patients: Role of the NaK-ATPase Pump

Studies of erythrocyte (RBC) cation fluxes and concentrations in hyperthyroid subjects have recently been reported with the suggestion that Na-K ATPase activity was decreased. We have studied tha kinetics of total and ouabain-sensitive K+ uptake utilizing 86Rb as a tracer in the intact erythrocytes of 7 hyperthyroid subjects and compared the results of those of a healthy control population. We find total K+ transport is depressed in the RBC of hyperthyroid subjects. The Vmax for K+ transport for hyperthyroid subjects is 1.8 +/- 0.17 x 10(-4) mM K+/10(9) RBC/hour versus a control of 2.3 +/- 0.14 x 10(-4) mM K+/10(9) RBC/hour. This depression in Vmax is evident in spite of no significant differences in the Km for the system when hyperthyroid subjects (2.7 +/- 0.19 mM) are compared to controls (2.38 +/- 0.21 mM). Further, the depressed K+ transport appears to be the result of depressed ouabain--insensitive K+ transport. Although the percent of the ouabain-sensitive K+ transport is greater in the hyperthyroid subject (82.5%) versus controls (72.5%), this simply reflects a relative change in a system where total transport is dropping but the ouabain-sensitive component is remaining unchanged. None of these findings can be directly or indirectly related to thyroid hormone and it is suggested that the ion transport changes reflect factors independent of thyroid hormone.
The effect of obesity on outcomes among injured patients.

INTRODUCTION The potential consequences of obesity in trauma patients are significant, yet incompletely defined by previous studies. OBJECTIVES To evaluate the effect of obesity on morbidity and mortality among injured patients. METHODS Medical records of all trauma patients evaluated at an American College of Surgeons verified Level I trauma center over a 1-year period were retrospectively reviewed. Morbidity and mortality were assessed after patients were stratified according to body mass index (BMI=kilograms/meters) and injury severity score. RESULTS The mortality of patients with a BMI > or =35 (obese patients) was 10.7% versus 4.1% for patients with a BMI<35 (lean patients, p = 0.003). Nearly 27% of obese patients versus 17.6% of lean patients experienced one or more complications while in the hospital (p = 0.02). CONCLUSIONS Obese patients are significantly more likely than lean patients to experience complications and death after a traumatic event. This effect is enhanced with higher levels of injury.
Systemic Increase of Oxidative Nucleic Acid Damage in Parkinson's Disease and Multiple System Atrophy

8-hydroxy-2'-deoxyguanosine (8-OHdG) or 8-hydroxyguanosine (8-OHG), a product of oxidized DNA or RNA, is a good marker of oxidative cellular damage. In this study, we measured the 8-OHdG/8-OHG levels in the serum and cerebrospinal fluid (CSF) of patients with Parkinson's disease (PD) and multiple system atrophy (MSA). Compared to age-matched controls, the mean levels of serum 8-OHdG/8-OHG were significantly higher in PD (P < 0.0001). Although no gender differences were observed in the controls, the mean values of serum 8-OHdG/8-OHG were significantly higher in female PD cases (P < 0.005) than in male patients. 8-OHdG/8-OHG levels in CSF were also increased significantly in patients with PD and MSA, however, their relative values were generally much lower than those in the serum. Together with previous studies showing increased peripheral 8-OHdG levels in Alzheimer's disease and amyotrophic lateral sclerosis, the data presented here suggest that systemic DNA/RNA oxidation is commonly observed in neurodegenerative diseases. Our results also imply that female patients with PD show higher levels of oxidative stress, which may explain the faster progression of this disease in females.
Characterization and pathogenicity of Yersinia pseudotuberculosis isolated from swine and other animals

Yersinia pseudotuberculosis serogroup III is most frequently detected in healthy pigs. Y. pseudotuberculosis strains were divided into two biogroups on the basis of their fermentation of melibiose. Melibiose-fermenting strains were distributed in all the hosts and serogroups examined. Melibiose-nonfermenting strains were limited to serogroup III isolated from healthy pigs. Autoagglutination and calcium dependency were not related to fermentation of melibiose. Melibiose-fermenting strains seem to be virulent for mice, but melibiose-nonfermenting strains showed no virulence for mice.
Analysis of mixed infection of sheep with bluetongue virus serotypes 10 and 17: evidence for genetic reassortment in the vertebrate host

Two seronegative sheep were infected intravenously with 10(9) PFU each of bluetongue virus (BTV) serotype 10 and BTV serotype 17. One animal experienced a mild bluetongue-like disease, and both experienced a short-duration viremia and developed neutralizing immune responses to both virus serotypes. Progeny virus was isolated from venous blood from each animal by using conditions in which reassortment could not have occurred during isolation. Electropherotypes were determined for the progeny viruses from the infected sheep, yielding strikingly similar results for the two animals. In both sheep, serotype 10 dominated among the progeny, accounting for 92% of the progeny. Serotype 17 was rarely isolated and accounted for 3% of the progeny analyzed. The remaining 5% of the progeny clones were reassortant and derived genome segments from both serotypes 10 and 17. Analysis of the parental origin of genome segments in the small number of reassortant progeny analyzed suggested that selection of specific genome segments may have occurred in the infected sheep. These data indicate that reassortment of genome segments occurs, at low frequency, in sheep mixedly infected with BTV.
Effect of continuous exenatide infusion on cardiac function and peri‐operative glucose control in patients undergoing cardiac surgery: A single‐blind, randomized controlled trial

We performed a randomized controlled trial with the glucagon‐like peptide‐1 (GLP‐1) receptor agonist exenatide as add‐on to standard peri‐operative insulin therapy in patients undergoing elective cardiac surgery. The aims of the study were to intensify peri‐operative glucose control while minimizing the risk of hypoglycaemia and to evaluate the suggested cardioprotective effects of GLP‐1‐based treatments. A total of 38 patients with decreased left ventricular systolic function (ejection fraction ≤50%) scheduled for elective coronary artery bypass grafting (CABG) were randomized to receive either exenatide or placebo in a continuous 72‐hour intravenous (i.v.) infusion on top of standard peri‐operative insulin therapy. While no significant difference in postoperative echocardiographic variables was found between the groups, participants receiving exenatide showed improved peri‐operative glucose control as compared with the placebo group (average glycaemia 6.4 ± 0.5 vs 7.3 ± 0.8 mmol/L; P < .001; percentage of time in target range of 4.5–6.5 mmol/L 54.8% ± 14.5% vs 38.6% ± 14.4%; P = .001; percentage of time above target range 39.7% ± 13.9% vs 52.8% ± 15.2%; P = .009) without an increased risk of hypoglycaemia (glycaemia <3.3 mmol/L: 0.10 ± 0.32 vs 0.21 ± 0.42 episodes per participant; P = .586). Continuous administration of i.v. exenatide in patients undergoing elective CABG could provide a safe option for intensifying the peri‐operative glucose management of such patients.
The Role of Deconditioning in the End-Stage Renal Disease Myopathy: Physical Exercise Improves Altered Resting Muscle Oxygen Consumption

Background: Skeletal muscle dysfunction and poor exercise tolerance are hallmarks of end-stage renal disease (ESRD). Noninvasively measured (near-infrared spectroscopy, NIRS) resting muscle oxygen consumption (rmVO2) is a biomarker of muscle dysfunction, which can be applied to study the severity and the reversibility of ESRD myopathy. We tested the hypothesis that deconditioning is a relevant factor in ESRD myopathy. Methods: The whole dialysis population (n = 59) of two of the eight centers participating into the EXCITE study (ClinicalTrials.gov NCT01255969), a randomized trial evaluating the effect of a home-based exercise program on the functional capacity of these patients was studied. Thirty-one patients were in the active arm (exercise group) and 28 in the control arm (no intervention). Normative data for rmVO2 were obtained from a group of 19 healthy subjects. Results: rmVO2 was twice higher (p < 0.001) in ESRDs patients (0.083 ± 0.034 ml/100 g/min) than in healthy subjects (0.041 ± 0.020 ml/100 g/min) indicating substantial skeletal muscle dysfunction in ESRD. rmVO2 correlated with resting heart rate (r = 0.34, p = 0.009) but was independent of age, dialysis vintage, biochemical, vascular and nutrition parameters. After the 6-month exercise program, rmVO2 reduced to 0.064 ± 0.024 ml/100 g/min (-23%, p < 0.001) in the exercise group indicating that skeletal muscle dysfunction is largely reversible but remained identical in the control group (0.082 ± 0.032 to 0.082 ± 0.031 ml/100 g/min). Conclusion: Deconditioning has a major role in ESRD myopathy. rmVO2 is a marker of physical deconditioning and has the potential for monitoring re-conditioning programs based on physical exercise in the ESRD population.
Creating Body Shapes From Verbal Descriptions by Linking Similarity Spaces

Brief verbal descriptions of people’s bodies (e.g., “curvy,” “long-legged”) can elicit vivid mental images. The ease with which these mental images are created belies the complexity of three-dimensional body shapes. We explored the relationship between body shapes and body descriptions and showed that a small number of words can be used to generate categorically accurate representations of three-dimensional bodies. The dimensions of body-shape variation that emerged in a language-based similarity space were related to major dimensions of variation computed directly from three-dimensional laser scans of 2,094 bodies. This relationship allowed us to generate three-dimensional models of people in the shape space using only their coordinates on analogous dimensions in the language-based description space. Human descriptions of photographed bodies and their corresponding models matched closely. The natural mapping between the spaces illustrates the role of language as a concise code for body shape that captures perceptually salient global and local body features.
