Social Ecology of Intelligence and Suicide in the United States

Two proxy variables for regional intelligence, state-level mean scores of 1994–2004 on the American College Test and of 1982, 1993, 1994, and 1998–2004 on the Scholastic Assessment Test, were consistently positively correlated with the averaged regional U.S. suicide rates of 1990–1994. The effects observed in these ecological (group-level) analyses were of small size, with correlation coefficients ranging from . 05 to . 25, thus mostly falling below the nominal statistical significance level. The present evidence nevertheless adds to several recent findings from international geographical studies by Lester and by Voracek of a positive association of intelligence and suicide mortality by indicating that this pattern may also exist on the within-nation level.
Gender and Cultural Differences in Teacher-Student Interpersonal Behavior.

The purpose of this study was to determine associations between science and mathematics students' perceptions of their classroom learning environments, the cultural backgrounds and gender of students, and their attitudinal and achievement outcomes. The subjects were 3,994 students from 182 secondary school science and mathematics classes in 35 coeducational schools in Western Australia and Tasmania. The students completed a survey including the Questionnaire on Teacher Interaction (QTI), an attitude to class scale, and questions relating to cultural background. Statistical analyses have confirmed the reliability and validity of the QTI for secondary school science and mathematics students. Generally, the dimensions of the QTI were found to be significantly associated with student attitude scores. In particular, students' attitude scores were higher in classrooms in which students perceived greater leadership, helping/friendly, and understanding behaviors in their teachers. Females perceived their teachers in a more positive way than did males, and students from an Asian background tended to perceive their teachers more positively than those from the other cultural groups used in the study.

Turning Towards or Turning Away: A Comparison of Mindfulness Meditation and Guided Imagery Relaxation in Patients with Acute Depression

Background: Disengaging from maladaptive thinking is an important imperative in the treatment of depression. Mindfulness training is aimed at helping patients acquire relevant skills for this purpose. It remains unclear, however, whether this practice is helpful when patients are acutely depressed. Aims: In order to investigate effects of mindfulness on symptoms and self-regulatory capacities in this group, the current study compared a brief training in mindfulness (n = 19) to guided imagery relaxation (n = 18). Method: Participants were introduced to the respective techniques in a single session, and practised daily over one week. Self-reported severity of symptoms, difficulties in emotion-regulation, attentional control, the ability to decentre, and mindfulness were assessed pre and postintervention, and at a one-week follow-up. Results: Symptoms of depression significantly decreased and self-regulatory functioning significantly increased in both groups, with changes being maintained during follow-up. When controlling for change in depressive symptoms, results showed significantly higher improvements in emotion regulation at follow-up in the mindfulness group. The ability to decentre predicted changes in symptoms from pre to postintervention, while mindfulness skills predicted changes in symptoms during the maintenance phase. Conclusions: The findings suggest that both practices can help to instigate reductions in symptoms and enhance self-regulatory functioning in depression. However, in order to improve emotion regulation above levels explained by reductions in symptoms more intentional mental training seems necessary. Furthermore, while the ability to disengage from negative patterns of thinking seems crucial for initial reduction of symptoms, maintenance of gains might require broader skills in mindfulness.
[Selection of genes related to multidrug resistance of pancreatic ductal adenocarcinoma by microarray analysis].

OBJECTIVE To investigate the genes concerning multidrug resistance (MDR) of pancreatic ductal adenocarcinoma with microarray analysis. METHODS Gene expression profile of pancreatic cancer cell line SW1990 and resistance subline SW1990/5-FU, SW1990/ADM, SW1990/GEM were screened in two independent replicates using oligonucleotide microarray (Affymetrix HG U133 2.0 plus) which contained 38,500 human genes. And advanced bioinformatics analysis was conducted. RESULTS Totally, 165 genes and expressed sequence tags (ESTs), which were seldom reported to be related with drug resistance before,were statistically difference and the fold change was up- or down-regulated at least 2 folds in all 3 resistant sub-lines when compared with SW1990. According gene ontology, the genes related to oxidoreductase activity, apoptosis, cell cycle, signal transduction and cell adhesion might be some epigenetic changes for MDR development. Hierarchical clustering analysis, showed several interesting clusters, namely, TNKS2, PRDX4 and CCDC4. CONCLUSIONS MDR of pancreatic cancer is a complicated and multifactorial process. In the present study, a widespread differential gene expression pattern was constructed in PDAC multidrug resistant cells. Advanced study will provide new targets for MDR research and cast insights into research of the molecular mechanism of MDR.
A novel preparation to study rat pancreatic spinal and vagal mechanosensitive afferents in vitro

Abstract The management of pancreatic pain is a significant clinical problem so understanding of how sensory signals are generated in pancreatic tissue is fundamental. We aimed to characterize mechanosensitive and chemosensitive properties of pancreatic spinal and vagal afferents in vitro. Spinal and vagal afferent preparations from Sprague–Dawley rats were established incorporating the left splanchnic nerve or vagus nerves respectively. The common bile duct was cannulated for distension of the pancreatic duct with fluid. Nerve discharge evoked by blunt probing, duct distension or electrical stimulation was obtained from teased nerve bundles using standard extra‐cellular recording. Discharge from 197 spinal afferent bundles was recorded, of which 57% displayed spontaneous activity. Blunt probing revealed 61 mechanosensitive receptive fields which were associated primarily with arteries/blood vessels (33/61) and the parenchyma (22/61). All mechanosensitive responses were slowly adapting, with 33% continuing to discharge after termination of the stimulus and 60% displaying a response threshold <10 g. Application of chemical mediators (bradykinin, histamine, 5‐hydroxytryptamine, cholecystokinin octapeptide) evoked a response from 31/57 units, with 33% excitatory and 23% inhibitory. Spontaneous discharge was recorded from 72% of 135 vagal bundles. Mechanosensitive receptive fields were not identified in the pancreas but were evident in adjacent organs. No spinal or vagal afferent response to duct distension was obtained. In conclusion, pancreatic mechanosensitive spinal afferents are common, in contrast to pancreatic mechanosensitive vagal afferents indicating that pancreatic sensory innervation is predominantly spinal. Chemosensitive spinal afferent nerve endings are present in the pancreas and respond to a variety of inflammatory and physiological mediators.
Novel P53 mutations detected by FAMA in colorectal cancers.

BACKGROUND The aim of the study was to identify p53 gene mutations by FAMA (fluorescence-assisted mismatch analysis) in colorectal cancers. PATIENTS AND METHODS Analytical scanning of the p53 gene (exons 5-9) was performed in colon cancer samples from 44 consecutive patients by FAMA. FAMA is a semiautomatic scanning approach based on the chemical cleavage of the mismatch in fluorescently labeled heteroduplex DNA, obtained from the combination of a normal and a mutated allele. FAMA has already shown optimal levels of diagnostic accuracy and sensitivity in detecting gene mutations (nucleotide substitutions, insertions/deletions) both at the germline and somatic level. The peculiar feature of FAMA is its ability to detect and localize mutations, by a redundant pattern of signals due to fluorescent DNA fragments generated by chemical cleavage. Moreover, previous data have demonstrated that normal contaminating DNA from stromal cells in the sample does not affect the sensitivity of the procedure, leading to the identification of the mutation even when the ratio mutant/normal allele is 10%. RESULTS Eighteen mutations (12 missense, one nonsense, two deletions, three nucleotide substitutions at the level of the splice-junctions) and two polymorphisms were detected by FAMA in 17 patients (39%) and then confirmed by automated sequence analysis. Six of 18 mutations (33%) were not previously reported for colon cancer samples and two of 18 lesions (11%) were identified as novel p53 mutations. CONCLUSIONS Analytical scanning of the p53 gene by FAMA in DNA from colon cancer samples provides a sensitive, accurate and specific diagnostic procedure for routine clinical application.
The disproportionate cost of smoking for African Americans in California.

OBJECTIVES We estimated the economic impact of smoking on African Americans in California in 2002, including smoking-attributable health care expenditures and productivity losses from smoking-caused mortality. METHODS We estimated econometric models of smoking-attributable ambulatory care, prescription drugs, inpatient care, and home health care using national and state survey data. We assessed smoking-attributable mortality using epidemiological models. RESULTS Adult smoking prevalence for African Americans was 19.3% compared with 15.4% for all Californians. The health care cost of smoking was $626 million for the African American community. A total of 3013 African American Californians died of smoking-attributable illness in 2002, representing a loss of over 49,000 years of life and $784 million in productivity. The total cost of smoking for this community amounted to $1.4 billion, or $1.8 billion expressed in 2008 dollars. CONCLUSIONS Although African Americans account for 6% of the California adult population, they account for over 8% of smoking-attributable expenditures and fully 13% of smoking-attributable mortality costs. Our findings confirm the need to tailor tobacco control programs to African Americans to mitigate the disproportionate burden of smoking for this community.
Buprenorphine differentially alters opioid receptor adaptation in rat brain regions.

Previous in vivo studies revealed that the mixed agonist-antagonist buprenorphine can down-regulate mu and up-regulate delta 2 and kappa 1 opioid receptors in rat brain. In this report brain regional differences in opioid receptor adaptation were addressed. Rats received i.p. injections with buprenorphine (0.5-2.5 mg/kg) and were killed 20 h later. Membranes from 7 brain regions were analyzed for mu (3H-[D-Ala2,N-mephe4,Gly-ol5] enkephalin), kappa 1 (3H-U-69593), delta 1 (3H-[D-Pen2, D-Pen5] enkephalin) and delta 2 (3H-deltorphin II) receptor binding parameters. Buprenorphine induced down-regulation of mu receptors in frontal cortex, occipital cortex, thalamus, hippocampus, striatum and brain stem. Kd values for 3H-[D-Ala2,N-mephe4,Gly-ol5] enkephalin were unchanged from controls. Up-regulation of kappa 1 receptors was observed in frontal, parietal, occipital cortexes and striatum. Binding to delta 2 sites was elevated in frontal and parietal cortexes. Buprenorphine did not alter delta 1 binding in any of the regions examined. Changes in opioid receptor adaptation induced by buprenorphine were further supported by data from cross-linking of 125I-beta-endorphin to cortical membrane preparations. A reduction in a 60- to 65-kDa band was detected in frontal and occipital cortices in which binding assays revealed down-regulation of mu receptors. In parietal cortex neither the 60- to 65-kDa product nor Bmax changes were observed. These results indicate that buprenorphine is a useful tool to study brain opioid receptor adaptation in vivo and the information accrued may be relevant to the mode of action of this drug in the treatment of heroin and cocaine abuse.
Combining ABCG2 Inhibitors with IMMU-132, an Anti–Trop-2 Antibody Conjugate of SN-38, Overcomes Resistance to SN-38 in Breast and Gastric Cancers

Sacituzumab govitecan (IMMU-132), an SN-38–conjugated antibody–drug conjugate, is showing promising therapeutic results in a phase I/II trial of patients with advanced Trop-2–expressing, metastatic, solid cancers. As members of the ATP-binding cassette (ABC) transporters confer chemotherapy resistance by active drug efflux, which is a frequent cause of treatment failure, we explored the use of known inhibitors of ABC transporters for improving the therapeutic efficacy of IMMU-132 by overcoming SN-38 resistance. Two human tumor cell lines made resistant to SN-38, MDA-MB-231-S120 (human breast cancer) and NCI-N87-S120 (human gastric cancer), were established by continuous exposure of the parental cells to stepwise increased concentrations of SN-38 and analyzed by flow cytometry for functional activities of ABCG2 and ABCB1, immunoblotting and qRT-PCR for the expression of ABCG2 at both protein and mRNA levels, and MTS assays for the potency of SN-38 alone or in combination with a modulator of ABC transporters. MDA-MB-231-S120 and NCI-N87-S120 displayed reduced sensitivity to SN-38 in vitro, with IC50 values approximately 50-fold higher than parental MDA-MB-231 and NCI-N87 cells. The increase in drug resistance of both S120 cell populations is associated with the expression of functional ABCG2, but not ABCB1. Importantly, treatment of both S120 sublines with known ABCG2 inhibitors (fumitremorgin C, Ko143, and YHO-13351) restored toxicity of SN-38, and the combination of YHO-13351 with IMMU-132 increased the median survival of mice bearing NCI-N87-S120 xenografts. These results provide a rationale for combination therapy of IMMU-132 and inhibitors of ABC transporters, such as YHO-13351. Mol Cancer Ther; 15(8); 1910–9. ©2016 AACR.
Towards Value-Based Professional Ethics in Public Administration

The postmodern administration redefines its role as ‘instance of mediation’ between the citizen and politics. Public administration has a double purpose; maintaining a political position of axiological neutrality, while showing the citizen transparency and encouragement to participate in all stages of the public decision, from adopting and implementing to its evaluation. In this paper, we will argue the importance of a public administration centred on ethical values. Public good, alongside justice, can be considered a constitutive ethical value of any type of public administration, and the values of equity transparency and responsibility, as ethical operational values of a contemporary public administration system. The constitutive values make necessary the emergence and functioning of a system of social institutions – in this case, those related to public administration. The ethical operational values are those values that manage the functioning of an institutional system and establish its limitations. We bring a series of arguments for replacing the distinction between intrinsic and extrinsic values with a distinction between constitutive and operational values, in the context of social-constructionist ethics development in public administration.
Effects of Fungicide Residues on the Survival, Fecundity, and Predation of the Mites Tetranychus urticae (Acari: Tetranychidae) and Galendromus occidentalis (Acari: Phytoseiidae)

Abstract Representative fungicides from three or four families used for management of powdery mildew and other diseases in tree fruits were evaluated for their effects on a common spider mite and predator mite species, respectively. A modified Munger cell technique was effective in measuring the response of phytophagous and predaceous mites to fungicide residues on detached leaves in the laboratory. Demethylation-inhibiting (DMI) (imidazole [triflumazole] and triazole [myclobutanil]) and strobilurin (trifloxystrobin) fungicides were not toxic to female Tetranychus urticae Koch and Galendromus occidentalis (Nesbitt), and no sublethal effects were found on fecundity and predation rate after 3–5-d exposure to residues. Benomyl, a benzimidazole fungicide, increased adult mortality and reduced fecundity for both mite species; however, it did not alter the predation rate of G. occidentalis females on T. urticae eggs and larvae. Female G. occidentalis that survived the lethal effects of benomyl and the comparison acaricide pyridaben were unimpaired in predation. Our results for benomyl substantiate those of earlier studies and provide evidence for nontoxic effects of DMI and strobilurin fungicides on mites. We propose that DMI and strobilurin fungicides are a good fit for integrated mite management programs due to conservation of phytoseiid predatory mites.
Enzootic Nasal Tumor Virus Envelope Requires a Very Acidic pH for Fusion Activation and Infection

ABSTRACT Enzootic nasal tumor virus (ENTV) is a close relative of jaagsiekte sheep retrovirus (JSRV), and the two viruses use the same receptor, hyaluronidase 2 (Hyal2), for cell entry. We report here that, unlike the JSRV envelope (Env) protein, the ENTV Env protein does not induce cell fusion at pHs of 5.0 and above but requires a much lower pH (4.0 to 4.5) for fusion to occur. The entry of ENTV Env pseudovirions was substantially inhibited by bafilomycin A1 (BafA1) but was surprisingly enhanced by lysosomotropic agents and lysosomal protease inhibitors following a 4- to 6-h treatment period; of note, prolonged treatment with BafA1 or ammonium chloride completely blocked ENTV entry. Unlike typical pH-dependent viruses, ENTV Env pseudovirions were virtually resistant to inactivation at a low pH (4.5 or 5.0). Using chimeras formed from ENTV and JSRV Env proteins, we demonstrated that the transmembrane (TM) subunit of ENTV Env is primarily responsible for its unusually low pH requirement for fusion but found that the surface (SU) subunit of ENTV Env also critically influences its relatively low and pH-dependent fusion activity. Furthermore, the poor infectivity of ENTV pseudovirions in human cells was significantly improved by either replacing the SU subunit of ENTV Env with that of JSRV Env or overexpressing the functional Hyal2 receptor in target cells, suggesting that ENTV SU-Hyal2 interaction is likely to be the limiting step for viral infectivity. Collectively, our data reveal that the fusogenicity of ENTV Env is intrinsically lower than that of JSRV Env and that ENTV requires a more acidic pH for fusion, which may occur in an intracellular compartment(s) distinct from that used by JSRV.
Errorless Compliance Training

Errorless compliance training is a noncoercive, success-focused approach to treatment of problem behavior in children. The intervention involves graduated exposure of a child to increasingly more challenging requests at a slow enough rate to ensure that noncompliance rarely occurs, providing parents with many opportunities to reinforce cooperative responses and rendering punishment unnecessary. The authors evaluated this approach with three boys with characteristics of Asperger syndrome. Mothers first delivered a range of requests to their children and recorded child responses. For each child, the authors calculated compliance probability for all requests and categorized them into four probability levels, from those yielding high compliance (Level 1) to those that commonly led to opposition (Level 4). Treatment began with delivery of Level 1 requests. Requests from Levels 2 through 4 were faded in sequentially over several weeks. All three children demonstrated substantial generalized improvement in compliance.
Thoracic muscle cross‐sectional area is associated with hospital length of stay post lung transplantation: a retrospective cohort study

Low muscle mass is common in lung transplant (LTx) candidates; however, the clinical implications have not been well described. The study aims were to compare skeletal muscle mass in LTx candidates with controls using thoracic muscle cross‐sectional area (CSA) from computed tomography and assess the association with pre‐ and post‐transplant clinical outcomes. This was a retrospective, single‐center cohort study of 527 LTx candidates [median age: 55 IQR (42–62) years; 54% male]. Thoracic muscle CSA was compared to an age‐ and sex‐matched control group. Associations between muscle CSA and pre‐transplant six‐minute walk distance (6MWD), health‐related quality of life (HRQL), delisting/mortality, and post‐transplant hospital outcomes and one‐year mortality were evaluated using multivariable regression analysis. Muscle CSA for LTx candidates was about 10% lower than controls (n = 38). Muscle CSA was associated with pre‐transplant 6MWD, but not HRQL, delisting or pre‐ or post‐transplant mortality. Muscle CSA (per 10 cm2 difference) was associated with shorter hospital stay [0.7 median days 95% CI (0.2–1.3)], independent of 6MWD. In conclusion, thoracic muscle CSA is a simple, readily available estimate of skeletal muscle mass predictive of hospital length of stay, but further study is needed to evaluate the relative contribution of muscle mass versus functional deficits in LTx candidates.
