A Clinical Protocol to Increase Chewing and Assess Mastication in Children With Feeding Disorders

Children with feeding disorders often cannot or do not chew when presented with table food. Children with chewing deficits also often swallow the bite before masticating it appropriately, which we will refer to as early swallowing. In the current study, we evaluated a clinical protocol to increase chews per bite, assess mastication, and eliminate early swallowing with three children with feeding disorders. The current study adds to a small body of literature on chewing and mastication of children with feeding disorders. Suggestions for future research are also discussed.
Son Preference, Sex Ratios, and Marriage Patterns

Preference for sons over daughters is widespread in many Asian countries, for example, India, China, and South Korea. This paper models endogenous sex choice and shows that unbalanced sex ratios are but one of several possible consequences of a preference for sons. In particular, if parents want children who reproduce, nonrandom mating may cause women to be consistently born into low‐status families and thus relegated to a permanent underclass. The paper also discusses possible links between son preference and marriage patterns such as spousal age gaps, hypergamy (women marrying up), caste endogamy, and cousin marriages.
Salinomycin Suppresses LRP6 Expression and Inhibits Both Wnt/β‐catenin and mTORC1 Signaling in Breast and Prostate Cancer Cells

Emerging evidence indicates that activation of Wnt/β‐catenin signaling at the cell surface results in inhibition of glycogen synthase kinase 3β (GSK3β), leading to activation of mTORC1 signaling in cancer cells. The low density lipoprotein receptor‐related protein‐6 (LRP6) is an essential Wnt co‐receptor for Wnt/β‐catenin signaling. Salinomycin is a novel small molecule inhibitor of LRP6. In the present study, we found that LRP6 overexpression induced mTORC1 signaling activation in cancer cells, and that salinomycin was not only a potent Wnt/β‐catenin signaling inhibitor, but also a strong mTORC1 signaling antagonist in breast and prostate cancer cells. Mechanistically, salinomycin activated GSK3β in cancer cells. Moreover, salinomycin was able to suppress the expression of cyclin D1 and survivin, two targets of both Wnt/β‐catenin and mTORC1 signaling, in prostate and breast cancer cells, and displayed remarkable anticancer activity. Our results present novel mechanisms underlying salinomycin‐mediated cancer cell death. J. Cell. Biochem. 115: 1799–1807, 2014. © 2014 Wiley Periodicals, Inc.
Genetic and molecular exploration of UHMK1 in schizophrenic patients

In two recent papers, polymorphisms located in U2AF homology motif kinase 1 (UHMK1) gene have been associated to schizophrenia. This gene encodes the serine/threonine kinase, kinase interacting with Stathmin, and has been functionally related to RNA metabolism and neurite outgrowth. In this study, we explored the contribution of this gene in schizophrenia susceptibility, using a case–control association study, a mutation screening, a transcription level analysis, and by the investigation of the phosphorylation status of the splicing factor, SF1, in B-lymphoblastoid cell lines of patients and controls. No association was observed in our French cohort, and no amino acid substitution was predicted in the subsample studied for mutation screening. No difference was observed in expression level or in SF1 phosphorylation between patients and controls. Despite a slight difference persisting in the meta-analysis carried out using four European populations, these data suggest, altogether, that UHMK1 does not play a major role in susceptibility to schizophrenia.
Technical Aspects in Laboratory Testing for Antiphospholipid Antibodies: Is Standardization an Impossible Dream?

Anticardiolipin (aCL) and anti-beta2 glycoprotein I (anti-beta2GPI) assays are widely performed because they are part of the laboratory criteria for the antiphospholipid syndrome (APS). Despite several standardization workshops and the availability of a worldwide accepted calibrator material for aCL, a high variability in numerical assay results and in sample classification is still observed in comparative studies and external quality control surveys. For anti-beta2GPI assays, comparison of numerical values is impeded by the absence of a common calibrator material, and external quality surveys similarly show a large overlap in sample classification. Numerous variables impact assay results, among them the source and integrity of beta2GPI, the secondary calibration process, and the assessment and derivation of cutoff values. For both assays, the vast majority of laboratories use commercial kits whose number has risen considerably in the past years. However, many problems persist, and there is a need to improve the comparability in assay results. The use of monoclonal antibodies as reference calibrators has to be especially considered, with their suitability evaluated by future collaborative studies and external quality controls surveys. Manufacturers should provide more precise information on results obtained when testing control groups for establishing reference ranges and cutoff values. From the customers' perspective, it is important that each laboratory, even if using commercial kits, assesses its local cutoff value whenever possible. In the field of autoimmunity, assay standardization is a difficult but nevertheless important task. Much more effort is needed to reduce the high interlaboratory variability in assay results even if absolute standardization cannot be feasibly achieved.
Different conformations of double‐stranded nucleic acid in solution as revealed by circular dichroism

Conformation of two‐stranded DNA in H2O–methanol, H2O–ethanol, H2O–isopropanol, and H2O–dioxane solutions at different concentrations of alkaline ions has been studied with the aid of circular dichroism. The following conclusions are drawn:
Burning mouth syndrome: a retrospective study investigating spontaneous remission and response to treatments.

OBJECTIVE The aim of this investigation was to evaluate the spontaneous remission rate of burning mouth syndrome (BMS) in a group of subjects suffering from this syndrome. SUBJECTS AND METHODS The medical records of BMS patients attending the Unit of Oral Medicine (1995-2002) were reviewed. The patients with a follow-up period of at least 18 months were then contacted over phone and interviewed using a structured ad hoc questionnaire to record their current symptoms and data about their treatment responses to the therapies. RESULTS Forty-eight women and five men with a mean age of 67.7 years (range 33-82 years) were included in the study (mean duration of BMS 5.5 years, s.d. +/-1.9 years, mean follow-up period of 56 months). As a consequence of different treatments, 26 patients (49.0%) reported no change in oral symptoms, 15 (28.3%) moderate improvement and 10 (18.9%) a worsening of oral complaints. Only two patients (3.7%) reported a complete spontaneous remission of oral symptoms without any treatment. CONCLUSIONS In this study, a complete spontaneous remission was observed in 3% of the patients within 5 years after the onset of BMS. A moderate improvement was obtained in <30% of the subjects.
Next-generation psychiatric assessment: Using smartphone sensors to monitor behavior and mental health.

OBJECTIVE Optimal mental health care is dependent upon sensitive and early detection of mental health problems. We have introduced a state-of-the-art method for the current study for remote behavioral monitoring that transports assessment out of the clinic and into the environments in which individuals negotiate their daily lives. The objective of this study was to examine whether the information captured with multimodal smartphone sensors can serve as behavioral markers for one's mental health. We hypothesized that (a) unobtrusively collected smartphone sensor data would be associated with individuals' daily levels of stress, and (b) sensor data would be associated with changes in depression, stress, and subjective loneliness over time. METHOD A total of 47 young adults (age range: 19-30 years) were recruited for the study. Individuals were enrolled as a single cohort and participated in the study over a 10-week period. Participants were provided with smartphones embedded with a range of sensors and software that enabled continuous tracking of their geospatial activity (using the Global Positioning System and wireless fidelity), kinesthetic activity (using multiaxial accelerometers), sleep duration (modeled using device-usage data, accelerometer inferences, ambient sound features, and ambient light levels), and time spent proximal to human speech (i.e., speech duration using microphone and speech detection algorithms). Participants completed daily ratings of stress, as well as pre- and postmeasures of depression (Patient Health Questionnaire-9; Spitzer, Kroenke, & Williams, 1999), stress (Perceived Stress Scale; Cohen et al., 1983), and loneliness (Revised UCLA Loneliness Scale; Russell, Peplau, & Cutrona, 1980). RESULTS Mixed-effects linear modeling showed that sensor-derived geospatial activity (p < .05), sleep duration (p < .05), and variability in geospatial activity (p < .05), were associated with daily stress levels. Penalized functional regression showed associations between changes in depression and sensor-derived speech duration (p < .05), geospatial activity (p < .05), and sleep duration (p < .05). Changes in loneliness were associated with sensor-derived kinesthetic activity (p < .01). CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Smartphones can be harnessed as instruments for unobtrusive monitoring of several behavioral indicators of mental health. Creative leveraging of smartphone sensing could provide novel opportunities for close-to-invisible psychiatric assessment at a scale and efficiency that far exceeds what is currently feasible with existing assessment technologies.
Can peripheral leukocytes be used as Alzheimer’s disease biomarkers?

Alzheimer’s disease (AD) is the leading cause of dementia in elderly populations throughout the world and its incidence is on the rise. Current clinical diagnosis of AD requires intensive examination that includes neuropsychological testing and costly brain imaging techniques, and a definitive diagnosis can only be made upon postmortem neuropathological examination. Additionally, antemortem clinical AD diagnosis is typically administered following onset of cognitive and behavioral symptoms. As these symptoms emerge relatively late in disease progression, therapeutic intervention occurs after significant neurodegeneration, thereby limiting efficacy. The identification of noninvasive diagnostic biomarkers of AD is becoming increasingly important to make diagnosis more widely available to clinics with limited access to neuropsychological testing or state-of-the-art brain imaging, reduce the cost of clinical diagnosis, provide a biological measure to track the course of therapeutic intervention, and most importantly, allow for earlier diagnosis – possibly even during the prodromal phase – with hopes of therapeutic intervention prior to appreciable neurodegeneration. Circulating leukocytes are attractive candidate AD biomarkers as they can be obtained in a minimally invasive manner and are easily analyzed by widely available flow cytometry techniques. In this review, we critically analyze the potential utility of peripheral leukocytes as biological markers for AD.
Response to recombinant hepatitis B vaccine in children and adolescents with chronic renal failure.

BACKGROUND Diminished antibody responses to the dosage of hepatitis B (HB) vaccine indicated for healthy adults has led to a greater dosage recommendation (40 microg of HB surface antigen [HBsAg]) for adults with chronic renal failure (CRF), but an appropriate dosage for children with CRF has not been established. METHODS Seventy-eight children and adolescents with CRF (22 patients, predialysis; 42 patients, chronic dialysis therapy; 14 renal transplant recipients) aged 1 to 19 years (mean, 10.1 years) were enrolled onto a study to test a three 20-microg dose course of the HB vaccine Recombivax HB (Merck & Co, Inc, West Point, PA). RESULTS The vaccine was well tolerated; no patient had a serious adverse event attributable to vaccine, and no patient withdrew from the study because of an adverse event. Overall, 91% of 66 patients administered three doses had a protective titer of 10 mIU/mL or greater for antibody against HBsAg (anti-HBs) and a geometric mean titer (GMT) of 733 mIU/mL, with seroprotection rates and GMTs among predialysis, dialysis, and renal transplant patients of 100% (4,140 mIU/mL), 94% (419 mIU/mL), and 64% (152 mIU/mL), respectively. All (100%) predialysis patients had a 10-mIU/mL or greater anti-HBs titer after only two doses of vaccine compared with 64% of dialysis patients and 50% of transplant recipients. Eighty-eight percent of 57 fully vaccinated patients tested 12 months after the first dose retained a 10-mIU/mL or greater anti-HBs titer. CONCLUSION A regimen of three 20-microg doses of Recombivax HB is suitably immunogenic for children with CRF not administered immunosuppressive medication. When possible, at least two, and preferably all three, doses of vaccine should be administered before progression to end-stage renal disease.
Actomyosin Organization in Mitotic Dictyostelium Amoebae a

Immunofluorescence localization of actin and myosin during mitosis indicates the significant roles of these cytoskeletons for cytokinesis. High frequency mitosis was induced by synchronous culture using temperature shift (T. Kitanishi-Yumura and Y. Fukui, 1987), and high resolution fluorescence microscopy was performed by the agar-overlay method (S. Yumura and Y. Fukui, 1984). It was shown that actin and myosin are dissociated from the cortex in prophase and reassembled in anaphase to form unique cortical structures: the contractile ring and/or polar lamellipodial network. Conventional myosin (myosin-II) is only localized in the contractile ring, whereas a low-molecular weight isozyme (myosin-I) is localized in the polar leading edge (Y. Fukui, T. Lynch, H. Brzeska, and E. Korn, 1989). Actin is localized in both structures and also forms a unique array in the furrow oriented perpendicular to the plane of constriction (Y. Fukui and S. Inoué, manuscript in preparation). The study suggests that conventional myosin provides the major force of constriction, whereas myosin-I participates in projecting lamellipodia, and actin is involved in several different functions in different regions of the cytoplasm.
Exploring the Relationship Between Professional Commitment and Job Satisfaction Among Nurses

This cross-sectional study explored the relationship between professional commitment and job satisfaction among nurses. A total of 132 registered nurses were recruited from a hospital in northern Taiwan. A self-reported structured questionnaire was used to collect data. Findings revealed significant differences among nurses in willingness to make an effort and their marital status, appraisal in continuing their careers, job level, and goals and values related to working shifts. Significant differences were found between inner satisfaction and work sector and marital status. Nurses’ professional commitment was strongly related to job satisfaction; aspects of professional commitment explained 32% of the variance in job satisfaction. Study results may inform health care institutions about the importance of nurses’ job satisfaction and professional commitment so hospital administration can improve these aspects of organizational environment.
Personality and College Major Choice: Which Come First?

The present study attempts to solve the nature of the known individual differences in personality related to academic college major choice. The question whether these precede or follow the choice of an academic major is still open. To rule out environmental influences during academic study, group differences in personality were assessed in perspective college students, thus before the incoming in a specific academic major. The Big Five Questionnaire-60 (BFQ; Caprara, Schwartz, Capanna, Vecchione, & Barbaranelli, 2006) and a questionnaire assessing the behavioural intention to enrol in different university faculties were administered to a sample of 886 last-year students who enrolled in different senior high schools. Among the Big-Five Factors, Extraversion and Conscientiousness have been found the explanatory variables predicting high-school students’expressed choice for their perspective academic career. These findings give a preliminary empirical support to the hypothesis of the pre-existence of group differences in personality at the moment of their choice for a specific academic career. Limitations and implications for future research are discussed.
N-Glycan-dependent and -independent Quality Control of Human δ Opioid Receptor N-terminal Variants*

Background: δ-Opioid receptor (δOR) F27C polymorphism affects receptor cell surface targeting. Results: If lacking N-glycans, Cys27, but not Phe27, is extensively targeted to endoplasmic reticulum-associated degradation and can escape to the cell surface in nonnative conformation. Conclusion: δOR relies on N-glycan-dependent calnexin-mediated quality control (QC) for correct folding, whereas N-glycan-independent QC is a backup system. Significance: Alternative QC pathways monitor nascent GPCRs. Quality control (QC) in the endoplasmic reticulum (ER) scrutinizes newly synthesized proteins and directs them either to ER export or ER-associated degradation (ERAD). Here, we demonstrate that the human δ-opioid receptor (hδOR) is subjected to ERQC in both N-glycan-dependent and -independent manners. This was shown by investigating the biosynthesis and trafficking of wild-type and non-N-glycosylated F27C variants in metabolic pulse-chase assays coupled with flow cytometry and cell surface biotinylation. Both QC mechanisms distinguished the minute one-amino acid difference between the variants, targeting a large fraction of hδOR-Cys27 to ERAD. However, the N-glycan-independent QC was unable to compensate the N-glycan-dependent pathway, and some incompletely folded non-N-glycosylated hδOR-Cys27 reached the cell surface in conformation incompatible with ligand binding. The turnover of receptors associating with the molecular chaperone calnexin (CNX) was significantly slower for the hδOR-Cys27, pointing to an important role of CNX in the hδOR N-glycan-dependent QC. This was further supported by the fact that inhibiting the co-translational interaction of hδOR-Cys27 precursors with CNX led to their ERAD. Opioid receptor pharmacological chaperones released the CNX-bound receptors to ER export and, furthermore, were able to rescue the Cys27 variant from polyubiquitination and retrotranslocation to the cytosol whether carrying N-glycans or not. Taken together, the hδOR appears to rely primarily on the CNX-mediated N-glycan-dependent QC that has the capacity to assist in folding, whereas the N-glycan-independent mechanism constitutes an alternative, although less accurate, system for directing misfolded/incompletely folded receptors to ERAD, possibly in altered cellular conditions.
Increased serum concentration of angiogenic factors in malignant melanoma patients correlates with tumor progression and survival.

PURPOSE To determine the predictive value of the angiogenic serum factors angiogenin, vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and interleukin-8 (IL-8) for the prognosis of patients with malignant melanoma. PATIENTS AND METHODS Angiogenin, VEGF, bFGF, and IL-8 were measured in sera of 125 melanoma patients with different stages of disease and with or without current therapy including interferon alfa and different cytostatics in comparison with 30 healthy controls using enzyme-linked immunosorbent assay. RESULTS Serum levels of angiogenin, VEGF, bFGF, and IL-8 were significantly increased in melanoma patients compared with healthy controls. Elevated serum concentrations of VEGF, bFGF, and IL-8 were associated with advanced disease stages and tumor burden. Cytostatic therapy of patients was accompanied by increased serum levels of angiogenin, bFGF, and IL-8. As shown by univariate analysis, elevated serum levels of VEGF (P = .0001 and .0036), bFGF (P < .00005 and < .00005), and IL-8 (P < .00005 and < .00005) were strongly correlated with a poor overall and progression-free survival, respectively. Multivariate analysis revealed stage of disease (P = .0238), tumor burden (P = .0347), VEGF (P = .0036), bFGF (P = .0252), and IL-8 (P = .0447) as independent predictive factors of overall survival. Tumor burden (P = .0081), VEGF (P = .0245), and IL-8 (P = .0089) were found as independent predictive factors of progression-free survival. CONCLUSION Our data suggest that the angiogenic serum factors VEGF, bFGF, and IL-8 are useful predictive markers for overall and progression-free survival in melanoma patients.
Characterization of the Mechanism for the Chronic Activation of Diacylglycerol-Protein Kinase C Pathway in Diabetes and Hypergalactosemia

Similar vascular pathological conditions are observed in diabetic animals and those with diet-induced hypergalactosemia. Both diabetes and hypergalactosemia are believed to cause vascular dysfunction via a common biochemical mechanism. In this study, we have found that both diabetes and hypergalactosemia in the short term (2–4 months) can increase total diacylglycerol (DAG) levels by 52 ± 9 and 74 ± 13% in the retina and aorta, respectively, of diabetic dogs, and by 94 ± 9 and 78 ± 11% in the retina and aorta, respectively, in dogs with hypergalactosemia as compared with normal control animals (P < 0.01). The elevation of DAG levels was maintained for 5 years in the aortas of diabetic and hypergalactosemic dogs. To characterize the mechanism of the DAG increases, we have determined that total DAG levels were significantly increased in cultured macro- and microvascular cells exposed to elevated glucose (22 mM) and galactose (16.5 mM) levels. These increased levels were not prevented by sorbinil, an aldose reductase inhibitor. One of the sources of the increased DAG levels was probably derived from de novo synthesis from both hexoses as determined by radiolabeling studies. Intracellularly, the DAG elevation activated protein kinase C (PKC) activity with increases of 58 ± 12% (P < 0.05) and 66 ± 8% (P < 0.01) in the membrane fraction of cultured aortic smooth muscle cells exposed to elevated glucose and galactose levels, respectively. These findings have clearly demonstrated a possible common biochemical mechanism by which hyperglycemia and hypergalactosemia can chronically activate the DAG-PKC pathway in the vasculature and could be a possible explanation for the development of diabetic vascular complications.
Personal Contextual Characteristics and Cognitions

According to Social Information Processing theory, parents’ cognitive processes influence their decisions to engage in physical maltreatment, although cognitions occur in the context of other aspects of the parents’ life. The present study investigated whether cognitive processes (external locus of control, inappropriate developmental expectations) predicted child abuse potential and overreactive disciplinary style beyond personal contextual factors characteristic of the parent (hostility, stress, and coping). 363 parents were recruited online. Results highlight the relative importance of the contextual characteristics (particularly stress, avoidant coping, and irritability) relative to cognitive processes in predicting abuse potential and overreactive discipline strategies, although an external locus of control also significantly contributed. Findings do not support that parents’ developmental expectations uniquely predict elevated abuse risk. Results indicate stressed parents who utilize avoidance coping strategies are more likely to use overreactive discipline and report increased abuse potential. Findings are discussed with regard to implications for prevention/intervention efforts.
