Longitudinal association between child stress and lifestyle.

OBJECTIVE Psychosocial stress has been linked with an unhealthy lifestyle but the relation's direction remains unclear. Does stress induce sleeping problems, comfort food consumption, and lower physical activity, or do these unhealthy lifestyle factors enhance stress? This study examined the bidirectional stress-lifestyle relation in children. METHOD The relation between stress and lifestyle was examined over 2 years in 312 Belgian children 5-12 years old as part of the Children's Body Composition and Stress study. Stress-related aspects were measured by questionnaires concerning negative events, negative emotions, and behavioral problems. The following lifestyle factors were assessed: physical activity (by accelerometers), sleep duration, food consumption (sweet food, fatty food, snacks, fruits and vegetables), and eating behavior (emotional, external, restrained). Bidirectional relations were examined with cross-lagged analyses. RESULTS Certain stress aspects increased physical activity, sweet food consumption, emotional eating, restrained eating, and external eating (βs = .140-.319). All relations were moderated by sex and age: Dietary effects were mainly in the oldest children and girls; stress increased physical activity in the youngest, whereas it tended to decrease physical activity in the oldest. One reversed direction effect was found: Maladaptive eating behaviors increased anxiety feelings. CONCLUSIONS Relations were mainly unidirectional: Stress influenced children's lifestyle. Stress stimulated eating in the absence of hunger, which could facilitate overweight. Consequently, families should realize that stress may influence children's diet, and problem-solving coping skills should be acquired. In contrast to recent findings, stress might also stimulate physical activity in the youngest as positive stress coping style.
Evidence for the Criterion Validity and Clinical Utility of the Pathological Narcissism Inventory

In this study, the authors evaluated aspects of criterion validity and clinical utility of the grandiosity and vulnerability components of the Pathological Narcissism Inventory (PNI) using two undergraduate samples (N = 299 and 500). Criterion validity was assessed by evaluating the correlations of narcissistic grandiosity and narcissistic vulnerability with established indices of normal personality traits, psychopathology and clinical concerns, and pathological personality traits. Overall, the pattern of correlations supported the convergent and discriminant validity of grandiose and vulnerable conceptualizations of pathological narcissism as measured by the PNI. Clinical utility was assessed by evaluating the extent to which clinicians without specific training in pathological narcissism as well as clinicians with expertise in pathological narcissism could accurately predict the correlates of PNI grandiosity and vulnerability with normal and pathological personality traits and psychopathology. The rcontrast-cv coefficient provided a global index of accuracy in clinicians’ predictions that was more fully elaborated by examining systematic discrepancies across groups. Overall, novice and expert clinicians were generally able to predict criterion correlations, with some exceptions (e.g., counter to predictions, pathological narcissism was negatively associated with treatment resistance). These results provide further evidence regarding the validity and utility of the narcissistic grandiosity and narcissistic vulnerability constructs as measured by the PNI.
Increased cancer burden among pesticide applicators and others due to pesticide exposure

A growing number of well‐designed epidemiological and molecular studies provide substantial evidence that the pesticides used in agricultural, commercial, and home and garden applications are associated with excess cancer risk. This risk is associated both with those applying the pesticide and, under some conditions, those who are simply bystanders to the application. In this article, the epidemiological, molecular biology, and toxicological evidence emerging from recent literature assessing the link between specific pesticides and several cancers including prostate cancer, non‐Hodgkin lymphoma, leukemia, multiple myeloma, and breast cancer are integrated. Although the review is not exhaustive in its scope or depth, the literature does strongly suggest that the public health problem is real. If we are to avoid the introduction of harmful chemicals into the environment in the future, the integrated efforts of molecular biology, pesticide toxicology, and epidemiology are needed to help identify the human carcinogens and thereby improve our understanding of human carcinogenicity and reduce cancer risk.

Melanization stimulating factor (MSF) and melanization inhibiting factor (MIF) in the integument of fish

The present studies were directed to demonstrate that adult fish skin contains putative factors that affect chromatophore and/or chromatoblast function. This hypothesis is based upon the possibility that hypo and/or hyperpigmented areas of the skin are so pigmented because of the localized expression of intrinsic factors that are either stimulatory or inhibitory to the differentiation of specific pigment cell types. In all the morphological and biochemical experiments carried out, we used culture media conditioned by dorsal (DCM) or ventral (VCM) skin from different species of fish. Both DCM and VCM were capable of stimulating differentiation of melanophores in neural crest explants. While the stimulation of melanization is an activity present in both dorsal and ventral skin, an inhibitory activity is also present in ventral skin at such a concentration that it overrides the stimulatory activity afforded by DCM. With biochemical assays, we demonstrated that the three important sequential enzymatic steps in melanogenesis are all stimulated by the conditioned media in a dose‐dependent manner and this results in an increase in the amount of melanin present in cultured cells. The results of our investigations provide strong evidence that there are intrinsic pigment cell regulatory factors in the integument of fish, the inhibitory activity being stronger in the ventrum, and that those factors strongly influence, perhaps even determine, the pigment patterns of fish.

A Cytosolic Amphiphilic α-Helix Controls the Activity of the Bile Acid-sensitive Ion Channel (BASIC)*

The bile acid-sensitive ion channel (BASIC) is a member of the degenerin/epithelial Na+ channel (Deg/ENaC) family of ion channels. It is mainly found in bile duct epithelial cells, the intestinal tract, and the cerebellum and is activated by alterations of its membrane environment. Bile acids, one class of putative physiological activators, exert their effect by changing membrane properties, leading to an opening of the channel. The physiological function of BASIC, however, is unknown. Deg/ENaC channels are characterized by a trimeric subunit composition. Each subunit is composed of two transmembrane segments, which are linked by a large extracellular domain. The termini of the channels protrude into the cytosol. Many Deg/ENaC channels contain regulatory domains and sequence motifs within their cytosolic domains. In this study, we show that BASIC contains an amphiphilic α-helical structure within its N-terminal domain. This α-helix binds to the cytosolic face of the plasma membrane and stabilizes a closed state. Truncation of this domain renders the channel hyperactive. Collectively, we identify a cytoplasmic domain, unique to BASIC, that controls channel activity via membrane interaction.
A protein secreted by the respiratory pathogen Chlamydia pneumoniae impairs IL‐17 signalling via interaction with human Act1

Chlamydia pneumoniae is a common respiratory pathogen that has been associated with a variety of chronic diseases including asthma and atherosclerosis. Chlamydiae are obligate intracellular parasites that primarily infect epithelial cells where they develop within a membrane‐bound vacuole, termed an inclusion. Interactions between the microorganism and eukaryotic cell can be mediated by chlamydial proteins inserted into the inclusion membrane. We describe here a novel C. pneumoniae‐specific inclusion membrane protein (Inc) CP0236, which contains domains exposed to the host cytoplasm. We demonstrate that, in a yeast two‐hybrid screen, CP0236 interacts with the NFκB activator 1 (Act1) and this interaction was confirmed in HeLa 229 cells where ectopically expressed CP0236 was co‐immunoprecipitated with endogenous Act1. Furthermore, we demonstrate that Act1 displays an altered distribution in the cytoplasm of HeLa cells infected with C. pneumoniae where it associates with the chlamydial inclusion membrane. This sequestration of Act1 by chlamydiae inhibited recruitment of the protein to the interleukin‐17 (IL‐17) receptor upon stimulation of C. pneumoniae‐infected cells with IL‐17A. Such inhibition of the IL‐17 signalling pathway led to protection of Chlamydia‐infected cells from NFκB activation in IL‐17‐stimulated cells. We describe here a unique strategy employed by C. pneumoniae to achieve inhibition of NFκB activation via interaction of CP0236 with mammalian Act1.

Dosage patterns in methadone treatment: results from a national survey, 1988-2005.

OBJECTIVE To examine the extent to which U.S. methadone maintenance facilities meet established standards for minimum dosages, 1988-2005. DATA SOURCE Data were collected from a nationally representative sample of outpatient treatment facilities in 1988 (n=172), 1990 (n=140), 1995 (n=116), 2000 (n=150), and 2005 (n=146). STUDY DESIGN Random-effects multiple regression analysis was used to examine unit characteristics associated with below recommended doses. DATA COLLECTION Data regarding the proportion of patients who received maintenance dosages of <40, 60, and 80 mg/day were collected from unit directors and clinical supervisors. PRINCIPAL FINDINGS Forty-four percent of patients receive doses of at least 80 mg/day--the threshold identified as recommended practice in recent work. Thirty-four percent of patients receive doses below 60 mg/day, while 17 percent receive doses below 40 mg/day. Units that serve a high proportion of African American or Latino clients were more likely to report low-dose care. Units managed by individuals who strongly favor abstinence models (e.g., Narcotics Anonymous) were more likely to provide low-dose care. CONCLUSIONS One-third of methadone facilities provide doses below recommended levels. Managerial attitudes about abstinence and their relationship to low doses underscore the contested role of methadone in treatment of opiate disorders.
Product Variety in Religious Markets

This paper analyzes the relationship between religious market product variety and church membership. We find that denominational variety is negatively associated with the total level of church membership in U.S. counties. This result appears 10 contradict the standard religious product variety model. Our data are consistent with a more general view of markets that incorporates the cost to consumers of product variety. Where product variety has significant costs, an increase in variety may reduce total market penetration. The paper suggests market characteristics that might give rise to this situation, characteristics present in the religion market.
An organoid and multi-organ developmental cell atlas reveals multilineage fate specification in the human intestine

Human intestinal organoids (HIOs) generated from pluripotent stem cells provide extraordinary opportunities to explore development and disease. Here, we generate a single-cell transcriptome reference atlas from HIOs and from multiple developing human organs to quantify the specificity of HIO cell fate acquisition, and to explore alternative fates. We identify epithelium-mesenchyme interactions, transcriptional regulators involved in cell fate specification, and stem cell maturation features in the primary tissue that are recapitulated in HIOs. We use an HIO time course to reconstruct the molecular dynamics of intestinal stem cell emergence, as well as the specification of multiple mesenchyme subtypes. We find that the intestinal master regulator CDX2 correlates with distinct phases of epithelial and mesenchymal development, and CDX2 deletion perturbs the differentiation of both intestinal epithelium and mesenchyme. Collectively our data provides a comprehensive and quantitative assessment of HIO development, and illuminates the molecular machinery underlying endodermal and mesodermal cell fate specification.
In Vivo Effects of Meloxicam, Celecoxib, and Ibuprofen on Free Radical Metabolism in Human Erythrocytes

Abstract One of the major groups of chemical mediators involved in the inflammatory response is the prostaglandins, which are synthesized from arachidonic acid by the enzyme cyclooxygenase. The aim of this study is to compare the in vivo effects of celecoxib, meloxicam, and ibuprofen on the activities of catalase (CAT), glutathione peroxidase (GSHPx), superoxide dismutase (SOD) as well as malondialdehyde (MDA), and antioxidant potential levels (AOP) in human erythrocytes. Patients diagnosed as osteoarthritis were included in the study. Patients were treated with Celecoxib (200 mg/d) (n = 12), Meloxicam (15 mg/d) (n = 12), and Ibuprufen (1200 mg/d) (n = 9) for 21 days. SOD, CAT, GSHPx activities, MDA, and AOP levels were investigated in human erythrocyte haemolysates. SOD activity and AOP levels were significantly decreased in all NSAID groups when we compared the values before and after 21 days of celecoxib, meloxicam, ibuprofen treatment. There were no significant difference in CAT, GSHPx activities, and MDA levels before and after treatment in each group. Decreased SOD activities are thought to be related with the increased superoxide anion. Decreased AOP levels may indicate impairment in the total antioxidant defence system. These NSAIDs have similar effects on free radical metabolism on human erythrocytes; despite some difference in action mechanisms.
DNA damage in human B cells can induce apoptosis, proceeding from G1/S when p53 is transactivation competent and G2/M when it is transactivation defective.

Cisplatin treatment of Epstein‐Barr virus‐immortalized human B lymphoblastoid cell lines (LCLs) results in p53‐mediated apoptosis which occurs largely in a population of cells at the G1/S boundary of the cell cycle. Cell cycle progression appears to be required for this apoptosis because arresting cells earlier in G1 inhibited apoptosis despite the accumulation of p53. Overexpression of wild‐type p53 also induces apoptosis in an LCL. Therefore six mutant genes derived from Burkitt's lymphoma (BL) cells were assayed for their ability to induce apoptosis when similarly overexpressed. The same genes were analysed in transient transfection assays for their ability to transactivate appropriate reporter plasmids. A correlation between the ability of p53 to transactivate and induce apoptosis was revealed. The only mutant capable of transactivation also induced apoptosis. Further analysis of the BL lines in which p53 had been characterized showed that whereas some lines were essentially resistant to cisplatin, three were rapidly induced to undergo apoptosis. All three have a single p53 allele encoding a mutant which is incapable of transactivation or (for two tested) mediating apoptosis when expressed in an LCL. Cell cycle analysis revealed that this apparently p53‐independent apoptosis did not follow G1 arrest but in fact occurred largely in cells distributed in the G2/M phase of the cell cycle. These data suggest the existence of a second checkpoint in the G2 or M phase which, in the absence of a functional p53, is the primary point of entry into the apoptosis programme following DNA damage.
Mechanisms of paradigm leveling and the role of universal preferences in morphophonological change

Historical linguists have long been divided in their views about the mechanisms behind paradigm leveling, with many invoking a special mechanism related to a universal preference for paradigm uniformity while others attribute leveling to the same mechanism responsible for other types of analogical change. I argue that although ‘proportional’ analogical innovation plays a major role in paradigm leveling, it cannot account for all cases, and that something akin to the ‘interference’ mechanisms commonly associated with contamination and folk etymology account well for the non-proportional instances. I further show that all of the mechanisms involved in paradigm leveling are also implicated in other types of analogical change, and I argue against the need to posit any universal bias against (stem) allomorphy.
REM sleep behaviour disorder differentiates pure autonomic failure from multiple system atrophy with autonomic failure

Ten patients with primary autonomic failure, followed up in a prospective clinical and laboratory study, were finally diagnosed as pure autonomic failure or multiple system atrophy with autonomic failure. Polysomnographic studies were performed in all patients. Whereas all four patients with multiple system atrophy complained of sleep related episodes suggesting REM sleep behaviour disorder (RBD) confirmed by polysomnography, RBD remained absent in the remaining six patients with pure autonomic failure. The data indicate that RBD is an important clinical feature, often heralding multiple system atrophy, but which is absent throughout the course of pure autonomic failure; its recognition can thus be useful in the prognostic evaluation of early primary autonomic failure syndromes.
Frequency estimation variance with the Burg algorithm

The variance of the Burg frequency estimate is computed for the simplest case of a single noisy complex sinusoid through a Monte Carlo simulation over a useful range of data lengths, signal-to-noise ratios, and model orders. It is demonstrated that it is possible to provide a reasonable fit to this data by a relatively simple expression which provides considerable insight into the performance of the Burg algorithm, especially when used in conjunction with the expression for the Cramer-Rao lower bound, which is itself particularly simple in this case. >
Estimation of tumor size in breast cancer comparing clinical examination, mammography, ultrasound and MRI-correlation with the pathological analysis of the surgical specimen.

BACKGROUND To evaluate the best method in our center to measure preoperative tumor size in breast tumors, using as reference the tumor size in the postoperative surgical specimen. We compared physical examination vs. mammography vs. resonance vs. ultrasound. There are different studies in the literature with disparate results. METHODS This is a retrospective study. All the included patients have been studied by clinical examination performed by gynecologist or surgeon specialists in senology, and radiological tests (mammography, ultrasound and magnetic resonance imaging). The correlation of mammary examination, ultrasound, mammography and resonance with pathological anatomy was studied using the Pearson index. Subsequently, the results of such imaging tests were compared with the tumor size of the infiltrating component measured by anatomopathological study using a student's t test for related variables. The level of significance was set at 95%. Statistical package R. was used. RESULTS A total of 73 cases were collected from October 2015 to July 2016 with diagnosis of infiltrating breast carcinoma. Twelve cases of carcinoma in situ and seven cases of neoadjuvant carcinoma are excluded. Finally, a total of 56 cases were included in the analysis. The mean age of the patients is 57 years. The histology is of infiltrating ductal carcinoma in 46 patients (80.7%), lobular in 8 (14%) and other carcinomas in 3 cases (5.2%). We verified the relationship between preoperative tumor size by physical examination, mammography, ultrasound (US) and magnetic resonance imaging (MRI), and the final size of the surgical specimen by applying a Pearson correlation test. A strong correlation was found between the physical examination results 0.62 (0.43-0.76 at 95% CI), ultrasound 0.68 (0.51-0.8 at 95% CI), mammography 0.57 (0.36-0.72 at 95% CI) and RM 0.51 (0.29-0.68 at 95% CI) with respect to pathological anatomy. The mean tumor size of the surgical specimen was 16.1 mm. Mean of tumor size by physical examination was 12.1 mm (P<0.05), by 14 mm US (P<0.05), by mammography of 14.3 (P<0.05) and by MRI of 22.53 mm (P>0.05). CONCLUSIONS Ultrasonography is the best predictor of tumor size in breast cancer, compared with clinical examination, mammography, and resonance. Our work could help the decision-making process such as the type of conservative surgery, the possible need for oncoplastic surgery or the decision to start treatment with neoadjuvant therapy, in patients with unifocal tumors.
The Multinationalization of the Transport Sector

According to the World Investment Report 2004, the structure of FDI has shifted towards services. Further, the composition of services FDI is also changing from trade and finance to such industries as electricity, water, telecommunications, storage and transportation. In the latter sector the value of FDI stock rose 16-fold between 1990 and 2002. Incorporating a transport sector dominated by multinationals and economies of scale in a model of the new trade theory leads to different predictions regarding the volume of trade and income as compared to a model with iceberg transport costs. It also opens up a further possibility for specialization. JEL classification: F12; F23
