General holistic impairment in congenital prosopagnosia: Evidence from Garner's speeded-classification task

Congenital prosopagnosia (CP), a lifelong impairment in face processing in the absence of brain damage, is often ascribed to impairment in holistic processing. It is still debated whether such difficulties are restricted to faces or whether they can also be observed for nonfacial stimuli. Here, we investigate this issue by examining CP individuals and their controls on two variations of the Garner speeded classification task tailored to assess holistic processing of nonfacial stimuli. In Experiment 1, participants were asked to judge the width of visually presented rectangles while ignoring their irrelevant height, or to judge changes in width while height remained constant. Critically, while controls exhibited the expected Garner interference, no such interference was observed for the CPs, indicating impaired holistic processing of integral, nonfacial shape dimensions. Experiment 2, utilized the same Garner paradigm, but here participants were asked to judge integral dimensions that are unrelated to shape (colour). Importantly, both CPs and controls exhibited the same level of Garner interference, indicating intact integral processing of colour dimensions. This dissociation between the performance on the two Garner tasks indicates that CPs do not exhibit a general local processing bias or impaired integration of any perceptual dimensions, but rather a deficit that is restricted to tasks requiring holistic integral perception of shape dimensions. Taken together, these results provide evidence for the existence of a general impairment in holistic shape perception in CP, which may be related to the mechanisms underlying this disorder.
Association of CNR1 and FAAH endocannabinoid gene polymorphisms with anorexia nervosa and bulimia nervosa: evidence for synergistic effects

Endocannabinoids modulate eating behavior; hence, endocannabinoid genes may contribute to the biological vulnerability to eating disorders. The rs1049353 (1359 G/A) single nucleotide polymorphism (SNP) of the gene coding the endocannabinoid CB1 receptor (CNR1) and the rs324420 (cDNA 385C to A) SNP of the gene coding fatty acid amide hydrolase (FAAH), the major degrading enzyme of endocannabinoids, have been suggested to have functional effects on mature proteins. Therefore, we explored the possibility that those SNPs were associated to anorexia nervosa and/or bulimia nervosa. The distributions of the CNR1 1359 G/A SNP and of the FAAH cDNA 385C to A SNP were investigated in 134 patients with anorexia nervosa, 180 patients with bulimia nervosa and 148 normal weight healthy controls. Additive effects of the two SNPs in the genetic susceptibility to anorexia nervosa and bulimia nervosa were also tested. As compared to healthy controls, anorexic and bulimic patients showed significantly higher frequencies of the AG genotype and the A allele of the CNR1 1359 G/A SNP. Similarly, the AC genotype and the A allele of the FAAH cDNA 385C to A SNP were significantly more frequent in anorexic and bulimic individuals. A synergistic effect of the two SNPs was evident in anorexia nervosa but not in bulimia nervosa. Present findings show for the first time that the CNR1 1359 G/A SNP and the FAAH cDNA 385C to A SNP are significantly associated to anorexia nervosa and bulimia nervosa, and demonstrate a synergistic effect of the two SNPs in anorexia nervosa.
Phylogenetic analysis of multiple FISH markers in oral tongue squamous cell carcinoma suggests that a diverse distribution of copy number changes is associated with poor prognosis

Oral tongue squamous cell carcinoma (OTSCC) is associated with poor prognosis. To improve prognostication, we analyzed four gene probes (TERC, CCND1, EGFR and TP53) and the centromere probe CEP4 as a marker of chromosomal instability, using fluorescence in situ hybridization (FISH) in single cells from the tumors of sixty‐five OTSCC patients (Stage I, n = 15; Stage II, n = 30; Stage III, n = 7; Stage IV, n = 13). Unsupervised hierarchical clustering of the FISH data distinguished three clusters related to smoking status. Copy number increases of all five markers were found to be correlated to non‐smoking habits, while smokers in this cohort had low‐level copy number gains. Using the phylogenetic modeling software FISHtrees, we constructed models of tumor progression for each patient based on the four gene probes. Then, we derived test statistics on the models that are significant predictors of disease‐free and overall survival, independent of tumor stage and smoking status in multivariate analysis. The patients whose tumors were modeled as progressing by a more diverse distribution of copy number changes across the four genes have poorer prognosis. This is consistent with the view that multiple genetic pathways need to become deregulated in order for cancer to progress.
Brief report: effects of pediatric HIV infection on mental and psychomotor development.

OBJECTIVE To examine the effect of HIV status on infants' mental and psychomotor functioning, controlling for confounding factors such as prenatal drug exposure and birth conditions. METHODS Twenty HIV-infected and 25 seroreverted infants (ages 3-30 months old) were administered the Bayley Scales of Infant Development (BSID) and a neurological examination at two time points, 4 to 12 months apart. The majority were from ethnic minority, socioeconomically disadvantaged families; 67% of the infants were prenatally drug-exposed. RESULTS HIV-infected infants had significantly lower scores on the BSID at baseline (mental development) and follow-up (motor development) compared to seroreverters. When HIV and neurological deficits were considered together, HIV+ children with neurological deficits scored significantly lower than HIV+ children without neurological deficits and seroreverters, with and without neurological diagnoses. Prenatal drug exposure was not associated with performance on the BSID. CONCLUSIONS These data suggest that CNS involvement is a critical pathway by which HIV affects infants' neurodevelopment.
Employability of mentally ill persons in India: A self-report-based population study

Introduction: The employment status of mentally ill patients is a reflection of their productivity, control of illness besides providing therapeutic benefits and integration into mainstream society. Owing to the associated stigma, self-reporting of mental illness (SRMI) often is rare. Census exercise of India in 2011 provides an insight of SRMI and employment status of such people. This study was undertaken to consider the role of gender, age group, and place on the employment status of SRMI. Methodology: Frequency of SRMI, age group, gender, and employment status was gathered from Indian 2011 census sources. Descriptive statistics and logistic regression were employed. P≤ 0.05 was taken as significant. Results: Majority (68.6%) of the SRMI people resides in rural areas, in the economically productive age group of 15–59 years (75.88%) and often males (57.51%). Of the SRMI as reported in the data, 78.62% were not employed while 2.4% of them were currently employed. The employability frequency distributions of SMRIs were statistically different in terms of area, age group, and gender with significance. Discussion: Although the mental illness data of 2011 census was rejected by mental health professionals citing discrepancy and underestimating of the prevalence of mental illness, it provides a robust estimate of the employability, self-reporting tendency of mental illness. The association of the factors provides a unique insight into SRMIs in India. Conclusion: Understanding the interplay of factors may yield robust estimates and clues for policy framers to formulate employment-related policies for employment opportunities for mentally ill patients.
Transient Receptor Potential Channels and Regulation of Lung Endothelial Permeability

This review highlights our current knowledge regarding expression of transient receptor potential (TRP) cation channels in lung endothelium and evidence for their involvement in regulation of lung endothelial permeability. Six mammalian TRP families have been identified and organized on the basis of sequence homology: TRPC (canonical), TRPV (vanilloid), TRPM (melastatin), TRPML (mucolipin), TRPP (polycystin), and TRPA (ankyrin). To date, only TRPC1/4, TRPC6, TRPV4, and TRPM2 have been extensively studied in lung endothelium. Calcium influx through each of these channels has been documented to increase lung endothelial permeability, although their channel-gating mechanisms, downstream signaling mechanisms, and impact on endothelial structure and barrier integrity differ. While other members of the TRPC, TRPV, and TRPM families may be expressed in lung endothelium, we have little or no evidence linking these to regulation of lung endothelial permeability. Further, neither the expression nor functional role(s) of any TRPML, TRPP, and TRPA family members has been studied in lung endothelium. In addition to this assessment organized by TRP channel family, we also discuss TRP channels and lung endothelial permeability from the perspective of lung endothelial heterogeneity, using outcomes of studies focused on TRPC1/4 and TRPV4 channels. The diversity within the TRP channel family and the relative paucity of information regarding roles of a number of these channels in lung endothelium make this field ripe for continued investigation.
Narratives About Mental Illnesses in China: The Voices of Generation Y

This study explores the cultured understanding of mental health and mental illnesses among members of Generation Y in China through a narrative approach. Five prominent narratives are identified through the analysis of stories about mental illnesses collected through semistructured interviews with college students. These five narratives feature the tragic genius, the psychotic criminal, the fragile victim, the antisocial recluse, and the homosexual. These narratives are gendered, in that women are the primary protagonists in the narrative about the fragile victim, while men are featured prominently in the narratives about the tragic genius, the psychotic criminal, and the antisocial recluse. Our study demonstrates that these narratives are based on, and will further reinforce, highly cultural-specific stereotypes and biases about mental illnesses in China. Theoretical and practical implications of this study are discussed.
Ground-Based Optical Measurements at European Flux Sites: A Review of Methods, Instruments and Current Controversies

This paper reviews the currently available optical sensors, their limitations and opportunities for deployment at Eddy Covariance (EC) sites in Europe. This review is based on the results obtained from an online survey designed and disseminated by the Co-cooperation in Science and Technology (COST) Action ESO903—“Spectral Sampling Tools for Vegetation Biophysical Parameters and Flux Measurements in Europe” that provided a complete view on spectral sampling activities carried out within the different research teams in European countries. The results have highlighted that a wide variety of optical sensors are in use at flux sites across Europe, and responses further demonstrated that users were not always fully aware of the key issues underpinning repeatability and the reproducibility of their spectral measurements. The key findings of this survey point towards the need for greater awareness of the need for standardisation and development of a common protocol of optical sampling at the European EC sites.
Overexpression and Characterization of the Human Peroxisomal Acyl-CoA Oxidase in Insect Cells (*)

Human liver peroxisomes contain two acyl-CoA oxidases, namely, palmitoyl-CoA oxidase and a branched chain acyl-CoA oxidase. The palmitoyl-CoA oxidase (ACOX) oxidizes the CoA esters of straight chain fatty acids and prostaglandins and donates electrons directly to molecular oxygen, thereby producing H2O2. The inducibility of this H2O2-generating ACOX in rat and mouse liver by peroxisome proliferators and the postulated role of the resulting oxidative stress in hepatocarcinogenesis generated interest in characterizing the structure and function of human ACOX. We have constructed a full-length cDNA encoding a 660-amino acid residue human ACOX and produced a catalytically active human ACOX protein at high levels in Spodoptera frugiperda (Sf9) insect cells using the baculovirus vector. Immunoblot analysis demonstrated that the full-length 72-kDa polypeptide (component A) was partially processed into its constituent 51-kDa (component B) and 21-kDa (component C) products, respectively. Recombinant protein (∼20 mg/1 × 109 cells) was purified to homogeneity by a single-step procedure on a nickel-nitrilo-triacetic acid affinity column. Using the purified enzyme, Km and Vmax values for palmitoyl-CoA were found to be 10 μM and 1.4 units/mg of protein, respectively. The maximal activities for saturated fatty acids were observed with C12-18 substrates. The overexpressed human ACOX protein was identified in the cytoplasm of the insect cells by immunocytochemical staining. Individual expression of either the truncated ACOX 51-kDa (component B) or the 21-kDa (component C) revealed lack of enzyme activity, but co-infection of the insect cells with recombinant viruses expressing components B and C resulted in the formation of an enzymatically active heterodimeric B + C complex which could subsequently be inactivated by dissociating with detergent.
Metabolic syndrome, proteinuria, and the risk of progressive CKD in hypertensive African Americans.

BACKGROUND Chronic kidney disease (CKD) is more likely to progress to kidney failure (end-stage renal disease) in African Americans, although the reasons for this are unclear. Metabolic syndrome is a risk factor for the development of diabetes and cardiovascular disease and recently was linked to incident CKD. The purpose of this study is to examine whether metabolic syndrome is associated with kidney disease progression in hypertensive African Americans. DESIGN & PARTICIPANTS The current study design is a secondary analysis of the African-American Study of Hypertension and Kidney Disease, a randomized controlled trial of blood pressure goal and agents in hypertensive African Americans with CKD. PREDICTORS Metabolic syndrome was defined according to the modified National Cholesterol Education Program guidelines. OUTCOMES Decrease in glomerular filtration rate of 50% or 25 mL/min/1.73 m(2), end-stage renal disease (initiation of dialysis therapy or transplantation), death, or a composite outcome of all 3. RESULTS 842 subjects were included in this analysis, and 41.7% met criteria for metabolic syndrome. Subjects meeting criteria for metabolic syndrome had greater levels of proteinuria. Cox regression analyses adjusted for age, sex, glomerular filtration rate, and other significant covariates except for proteinuria indicated a 31% increased risk, with a 95% confidence interval of 1.03 to 1.7 (P = 0.03) for time to reach the composite outcome in those with metabolic syndrome. Adjusting for proteinuria, the effect was abated to 16% (95% confidence interval, 0.9 to 1.5), no longer remained significant (P = 0.2), and was unchanged by adjusting randomized treatment group (blood pressure goal or antihypertensive drug). LIMITATIONS Lack of waist circumference as a better surrogate of abdominal obesity. CONCLUSIONS In summary, metabolic syndrome is associated with proteinuria in hypertensive African Americans, but is not independently associated with CKD progression.
A Disaccharide-Based Inhibitor of Glycosylation Attenuates Metastatic Tumor Cell Dissemination

Purpose: The binding of hematogenously borne malignant cells that express the carbohydrate sialyl Lewis X (sLeX) to selectin adhesion receptors on leukocytes, platelets, and endothelial cells facilitates metastasis. The glycosylation inhibitor, per-O-acetylated GlcNAcβ1,3Galβ-O-naphthalenemethanol (AcGnG-NM), inhibits the biosynthesis of sLeX in tumor cells. To evaluate the efficacy of AcGnG-NM as an antimetastatic agent, we examined its effect on experimental metastasis and on spontaneous hematogenous dissemination of murine Lewis lung carcinoma and B16BL6 melanoma cells. Experimental Design: Tumor cells were treated in vitro with AcGnG-NM, and the degree of selectin ligand inhibition and experimental metastasis was analyzed in wild-type and P-selectin-deficient mice. Conditions were developed for systemic administration of AcGnG-NM, and the presence of tumor cells in the lungs was assessed using bromodeoxyuridine labeling in vivo. The effect of AcGnG-NM on inflammation was examined using an acute peritonitis model. Results:In vitro treatment of Lewis lung carcinoma cells with AcGnG-NM reduced expression of sLeX- and P-selectin-dependent cell adhesion to plates coated with P-selectin. Treatment also reduced formation of lung foci when cells were injected into syngeneic mice. Systemic administration of the disaccharide significantly inhibited spontaneous dissemination of the cells to the lungs from a primary s.c. tumor, whereas an acetylated disaccharide not related to sLeX in structure had no effect. AcGnG-NM did not alter the level of circulating leukocytes or platelets, the expression of P-selectin ligands on neutrophils, or sLeX-dependent inflammation. Conclusion: Taken together, these data show that AcGnG-NM provides a targeted glycoside-based therapy for the treatment of hematogenous dissemination of tumor cells.
Lipid peroxidation and antioxidant enzymes in male infertility.

BACKGROUND AND AIM Mammalian spermatozoa are rich in polyunsaturated fatty acids and are very susceptible to attack by reactive oxygen species (ROS) and membrane lipid peroxide ion. Normally a balance is maintained between the amount of ROS produced and that scavenged. Cellular damage arises when this equilibrium is disturbed. A shift in the levels of ROS towards pro-oxidants in semen and vaginal secretions can induce an oxidative stress on spermatozoa. The aim was to study lipid peroxidation and antioxidant enzymes such as catalase, glutathione peroxidase and superoxide dismutase (SOD) and to correlate the same, with the 'water test', in male infertility. SETTINGS Experimental study. SUBJECTS AND METHODS Ejaculates from a total of 83 infertile and fertile healthy individuals were obtained. Lipid peroxidation and antioxidant enzyme levels were studied and correlated with water test. RESULTS The results indicate that (i) the antioxidant enzyme catalase showed no significant changes in the various pathological samples, (ii) antioxidant enzymes SOD and glutathione peroxidase correlate positively with asthenozoospermic samples and (iii) the degree of lipid peroxidation also correlates positively with the poorly swollen sperm tails. The increase in SOD and glutathione peroxidase values, in the pathological cases represents an attempt made to overcome the reactive oxygen species. CONCLUSION Water test could be used as a preliminary marker test for sperm tail damage by reactive oxygen species, since it correlates very well with lipid peroxidation and antioxidant enzymes.
Impact of Polarity of Gate Bias and Hf Concentration on Breakdown of HfSiON/ $\hbox{SiO}_{2}$ Gate Dielectrics

We have investigated the impact of polarity of gate bias and Hf concentration on HfSiON/SiO2 gate dielectric breakdown (DB) with time-zero DB (TZDB) and time-dependent DB (TDDB). At TZDB, the gate leakage currents at breakdown (BD) under negative bias are much smaller than those with positive bias without regard to accumulation or inversion states. Since the electric fields at BD are not all the same, the BD mechanism cannot be explained with a simple thermochemical model for all types of stress for HfSiON gate dielectric. With TDDB, the electric-field acceleration constant is dependent on the Hf concentration. Calculated active dipole moments in HfSiON have been shown to be similar to theoretical values for nMOS but not pMOS. Thermochemic BD of HfSiON, itself (not interface SiO2), is adequate to describe nMOS in the inversion state. On the other hand, the BD of pMOS in the inversion state is affected by the carrier currents and not the electric fields as the TZDB. The BD mechanisms are strongly dependent on both the polarity of the gate bias and the Hf concentration.
Preprocedural evaluation: considerations outside of the operating room

Purpose of review There are an increasing number of procedures performed in locations outside of the operating room both for children and adults. From the perspective of the anesthesiologist, the preprocedural evaluation is essential in providing safe and high-quality care. This review focuses on the purpose, considerations and methods for providing information during the preprocedural evaluation process based on the most recent literature review. Recent findings Upon review of the literature, there is an agreement that a preprocedural evaluation is fundamental to the management of our patients. This evaluation is the process of clinical assessment that precedes the delivery of anesthesia for all procedures. Consideration must be given to information from many sources and consultation ordered only as necessary. A determination of the medical condition as indicated by the American Society of Anesthesiologists score must be applied. The evaluation process is relatively standard across institutions. It appears to be more clearly defined among adult patients particularly when presenting with multiple comorbidities, and will tend to be assessed days to weeks prior to the scheduled procedure. Differences may exist, however, among an institutions’ overall approach to the preprocedural evaluation of children. Ultimately, the results are efforts by the institutions to improve efficiency, reduce delays and cancellation rates. Summary It is important for the anesthesia provider to perform a thorough preprocedural evaluation. Tests that are ordered as part of the evaluation are done to understand the current medical state, verify a condition or formulate a plan. Informed consent must be obtained and the risks and benefits of the anesthesia plan in a manner understandable to the patient and parent or care giver. Many pediatric patients undergoing procedures outside of the operating room are in good health, and their evaluation will be relatively routine. Other children will present with complex medical conditions that require more time for the evaluation process. This may include the consultation of a pediatric specialist(s) as a necessary step toward completion of the preprocedural evaluation. Similarly, there are adult patients undergoing procedures outside of the operating room, which will have a straightforward preprocedural evaluation and others are more complex. Disease states that might require further testing include diabetes, leukemia, kidney and liver disease, central nervous system disease, malabsorption syndrome, coronary artery disease, coagulopathies and patients on diuretics.
