Detecting the needs for happiness and meaning in life from google books

Research has shown that subjective well-being has two related but distinct dimensions, eudaimonic well-being and hedonic well-being. Hedonic well-being refers to one's overall positive affective experiences, while eudaimonic well-being is related to having a meaningful and noble purpose for life. While people are striving to have a happy and meaningful life, their motivations can be influenced by socio-economic conditions and contexts. In this study, we analyzed words frequencies in the Google Books corpus to measure the changing needs for eudaimonic and hedonic well-being and their relationships with economic growth. Results show that the frequencies of words related to hedonic well-being decrease while those related to eudaimonic well-being increase over the years. Furthermore, when people are poor, their motivation for hedonic well-being is relatively high. The hedonic motivational strength dramatically decreases and becomes stable when income reaches at a certain level. In contrast, people have relatively low motivation for eudaimonic well-being when they are poor. The eudaimonic motivational strength dramatically increases and becomes stable when income reaches at a certain level. Our study demonstrates an example of measuring subjective well-being through analysis of digital media.
Menadione‐induced caspase‐dependent programmed cell death in the green chlorophyte Chlamydomonas reinhardtii

Menadione, a quinone that undergoes redox cycles leading to the formation of superoxide radicals, induces programmed cell death (PCD) in animals and plants. In this study, we investigated whether the unicellular green alga Chlamydomonas reinhardtii P.A. Dangeard is capable of executing PCD upon exposure to menadione stress. We report here, the morphological, molecular, and biochemical changes after menadione exposure of C. reinhardtii cells. The effect of menadione on cell death has been shown to be dose‐dependent; 5–100 μM menadione causes 20%–46% cell death, respectively. It appears that growth is inhibited with the concomitant degradation of the photosynthetic pigments and by a decrease in the photosynthetic capacity. Being an oxidative stress, we found an H2O2 burst within 15 min of menadione exposure, followed by an increase in antioxidant enzyme (superoxide dismutase [SOD], catalase [CAT], and ascorbate peroxidase [APX]) activities. In parallel, RT‐PCR was performed for transcript analyses of Mn‐SOD, CAT, and APX. Our results clearly revealed that expression of these genes were up‐regulated upon menadione exposure. Furthermore, classical hallmarks of PCD such as alteration of mitochondrial membrane potential, significant increase in caspase‐3‐like DEVDase activity, cleavage of poly (ADP) ribose polymerase (PARP)‐1‐like enzyme, and DNA fragmentation as detected by terminal deoxynucleotidyl transferase‐mediated dUTP nick end‐labeling (TUNEL) assay and oligosomal DNA fragmentation were observed. Moreover, antibodies against a mammalian active caspase‐3 shared epitopes with a caspase‐3‐like protein of ~17 kDa; its pattern of expression and activity correlated with the onset of cell death. To the best of our knowledge, this is the first report on menadione‐induced PCD through a mitochondrian‐caspase protease pathway in an algal species.
Multiple identities of Jewish immigrant adolescents from the former Soviet Union: An exploration of salience and impact of ethnic identity

The current paper explores the salience and impact of ethnic and national identities for immigrants that are negotiating more than two cultures. Specifically, we were interested in the ways in which Jewish immigrant adolescents from the former Soviet Union integrate their Russian, Jewish, and American identities, and to what extent identification with these three cultures predicts adaptation to varied life domains. In order to examine whether being Jewish has an impact on salience and predictive value of Russian and American identities, a sample of Jewish adolescents (n = 100) was compared with a sample of non-Jewish (n = 113) adolescent immigrants from the former Soviet Union. The study suggests that Jewish and non-Jewish adolescent immigrants differ in levels of Russian and American identity. Further, using structural equation modeling a bicultural model for Jewish and non-Jewish adolescents was tested. The results suggest that these two groups do not differ with respect to how Russian and American identities impact on adjustment. However, adding Jewish identity to the model for the Jewish sample significantly improved model fit, and rendered some of the impact of Russian identity non-significant. Thus a multicultural model that included all three identities had better explanatory power for this sample than a bicultural one. Implications for the study of ethnic identity of immigrants, particularly those whose lives involve multiple cultural affiliations, are drawn.
Can physicians conceive of performing euthanasia in case of psychiatric disease, dementia or being tired of living?

Background Euthanasia and physician-assisted suicide (EAS) in patients with psychiatric disease, dementia or patients who are tired of living (without severe morbidity) is highly controversial. Although such cases can fall under the Dutch Euthanasia Act, Dutch physicians seem reluctant to perform EAS, and it is not clear whether or not physicians reject the possibility of EAS in these cases. Aim To determine whether physicians can conceive of granting requests for EAS in patients with cancer, another physical disease, psychiatric disease, dementia or patients who are tired of living, and to evaluate whether physician characteristics are associated with conceivability. A cross-sectional study (survey) was conducted among 2269 Dutch general practitioners, elderly care physicians and clinical specialists. Results The response rate was 64% (n=1456). Most physicians found it conceivable that they would grant a request for EAS in a patient with cancer or another physical disease (85% and 82%). Less than half of the physicians found this conceivable in patients with psychiatric disease (34%), early-stage dementia (40%), advanced dementia (29–33%) or tired of living (27%). General practitioners were most likely to find it conceivable that they would perform EAS. Conclusions This study shows that a minority of Dutch physicians find it conceivable that they would grant a request for EAS from a patient with psychiatric disease, dementia or a patient who is tired of living. For physicians who find EAS inconceivable in these cases, legal arguments and personal moral objections both probably play a role.
Phosphatidylinositol 3-Kinase Regulates the CD4/CD8 T Cell Differentiation Ratio1

The signaling pathways that control T cell differentiation have only begun to be elucidated. Using T cell lines, it has been shown that class IA phosphatidylinositol 3-kinase (PI3K), a heterodimer composed of a p85 regulatory and a p110 catalytic subunit, is activated after TCR stimulation. Nonetheless, the contribution of p85/p110 PI3K isoforms in T cell development has not been described. Mice deficient in the other family of class I PI3K, p110γ, which is regulated by G protein-coupled receptors, exhibit reduced thymus size. Here we examine T cell development in p110γ-deficient mice and in mice expressing an activating mutation of the p85 regulatory subunit, p65PI3K, in T cells. We show that p110γ-deficient mice have a partial defect in pre-TCR-dependent differentiation, which is restored after expression of the p65PI3K activating mutation. Genetic alteration of both PI3K isoforms also affects positive selection; p110γ deletion decreased and p65PI3K expression augmented the CD4+/CD8+ differentiation ratio. Finally, data are presented showing that both PI3K isoforms influenced mature thymocyte migration to the periphery. These observations underscore the contribution of PI3K in T cell development, as well as its implication in determining the CD4+/CD8+ T cell differentiation ratio in vivo.
Endogenous Arginine-Phenylalanine-Amide-related Peptides Alter Steady-state Desensitization of ASIC1a*

The acid-sensing ion channels (ASICs) are proton-gated, voltage-insensitive cation channels expressed throughout the nervous system. ASIC1a plays a role in learning, pain, and fear-related behaviors. In addition, activation of ASIC1a during prolonged acidosis following cerebral ischemia induces neuronal death. ASICs undergo steady-state desensitization, a characteristic that limits ASIC1a activity and may play a prominent role in the prevention of ASIC1a-evoked neuronal death. In this study, we found exogenous and endogenous arginine-phenylalanine-amide (RF-amide)-related peptides decreased the pH sensitivity of ASIC1a steady-state desensitization. During conditions that normally induced steady-state desensitization, these peptides profoundly enhanced ASIC1a activity. We also determined that human ASIC1a required more acidic pH to undergo steady-state desensitization compared with mouse ASIC1a. Surprisingly, steady-state desensitization of human ASIC1a was also affected by a greater number of peptides compared with mouse ASIC1a. Mutation of five amino acids in a region of the extracellular domain changed the characteristics of human ASIC1a to those of mouse ASIC1a, suggesting that this region plays a pivotal role in neuropeptide and pH sensitivity of steady-state desensitization. Overall, these experiments lend vital insight into steady-state desensitization of ASIC1a and expand our understanding of the structural determinants of RF-amide-related peptide modulation. Furthermore, our finding that endogenous peptides shift steady-state desensitization suggests that RF-amides could impact the role of ASIC1a in both pain and neuronal damage following stroke and ischemia.
Seismic attenuation and velocity dispersion in heterogeneous partially saturated porous rocks

SUMMARY Using a numerical approach, we explore wave-induced fluid flow effects in partially saturated porous rocks in which the gas–water saturation patterns are governed by mesoscopic heterogeneities associated with the dry frame properties. The link between the dry frame properties and the gas saturation is defined by the assumption of capillary pressure equilibrium, which in the presence of heterogeneity implies that neighbouring regions can exhibit different levels of saturation. To determine the equivalent attenuation and phase velocity of the synthetic rock samples considered in this study, we apply a numerical upscaling procedure, which permits to take into account mesoscopic heterogeneities associated with the dry frame properties as well as spatially continuous variations of the pore fluid properties. The multiscale nature of the fluid saturation is taken into account by locally computing the physical properties of an effective fluid, which are then used for the larger-scale simulations. We consider two sets of numerical experiments to analyse such effects in heterogeneous partially saturated porous media, where the saturation field is determined by variations in porosity and clay content, respectively. In both cases we also evaluate the seismic responses of corresponding binary, patchy-type saturation patterns. Our results indicate that significant attenuation and modest velocity dispersion effects take place in this kind of media for both binary patchy-type and spatially continuous gas saturation patterns and in particular in the presence of relatively small amounts of gas. The numerical experiments also show that the nature of the gas distribution patterns is a critical parameter controlling the seismic responses of these environments, since attenuation and velocity dispersion effects are much more significant and occur over a broader saturation range for binary patchy-type gas–water distributions. This analysis therefore suggests that the physical mechanisms governing partial saturation should be accounted for when analysing seismic data in a poroelastic framework. In this context, heterogeneities associated with the dry frame properties, which do not play important roles in wave-induced fluid flow processes per se, should be taken into account since they may determine the kind of gas distribution pattern taking place in the porous rock.
Relationship between serum adiponectin concentration, pulse wave velocity and nonalcoholic fatty liver disease.

OBJECTIVES We aimed to investigate the relationship between nonalcoholic fatty liver disease (NAFLD), serum adiponectin concentration and brachial-ankle pulse wave velocity (baPWV) as a risk marker for atherosclerosis. METHODS A total of 213 nonalcoholic subjects (67 males, 146 females) participated in this study. Division of subjects into the NAFLD group or the normal group was based on the existence of fatty liver detected by sonography. RESULTS Serum adiponectin levels in the NAFLD group were significantly lower than those in the normal group. After adjusting for age, body-mass index (BMI) and the homeostasis model of assessment (HOMA), there was a significant negative correlation between NAFLD and serum adiponectin level only in females (r = -0.22, P = 0.008). Multiple logistic regression analysis showed a tendency of inverse correlation between NAFLD and serum adiponectin level in females (P = 0.055). After adjustment for age, BMI and HOMA value, serum adiponectin levels were inversely correlated with serum alanine aminotransferase (ALT) and gamma-glutamyltranspeptidase (GGT) levels (r = -0.199 (P = 0.004) and r = -0.282 (P < 0.001)). On the other hand, baPWV in the NAFLD group was also significantly higher than that in the normal group in females (P = 0.005). Individual levels of serum ALT, aspatate aminotransferase (AST), alkaline phosphatase (ALP) and GGT were positively correlated with baPWV after adjusting for age, sex, BMI, HOMA and systolic blood pressure (P < 0.05). CONCLUSION Serum adiponectin level and baPWV were significantly associated with NAFLD and various liver enzymes, especially in females.
Diagnostic approach to urinary tract infections in male general practice patients: a national surveillance study.

BACKGROUND Diagnostic urinary tract infection (UTI) studies have primarily been performed among female patients. AIM To create a diagnostic algorithm for male general practice patients suspected of UTI. DESIGN AND SETTING Surveillance study in the Dutch Sentinel General Practice Network. METHOD Clinical information and dipstick results were collected from 603 patients. Algorithm-predicted care was compared with care as usual in terms of sensitivity (antibiotic recommended when UTI was confirmed) and specificity (no antibiotic recommended when no UTI was observed). RESULTS Complete information was available from 490/603 (81%) males, of whom 66% (321/490) had a UTI. A diagnostic algorithm recommending antimicrobial prescription in the case of a positive nitrite test or a positive leukocyte esterase test in males aged ≥60 years, had a positive predictive value (PPV) of 83% (95% confidence interval [CI] = 78 to 87) and a negative predictive value (NPV) of 60% (95% CI = 52 to 66), respectively (area under the ROC curve: 0.78, 95% CI = 0.74 to 0.82). When both dipstick results were positive in males aged ≥60 years, PPV increased to 90% (95% CI = 83 to 94), whereas NPV was highest in males <60 years with negative dipstick results (71%, 95% CI = 59 to 81). Sensitivity and specificity of predicted UTI care and usual care did not differ (75% versus 79%, P = 0.30, and 70% versus 63%, P = 0.17, respectively). CONCLUSION UTI care provided to Dutch male GP patients is as accurate as predicted care from a diagnostic algorithm. The studied clinical information and dipstick tests are useful for ruling in UTI in males, but have limited value in ruling out this diagnosis.
Tumors with Nonfunctional Retinoblastoma Protein Are Killed by Reduced γ-Tubulin Levels

Background: γ-Tubulin moderates the expression of E2F-regulated promoters by direct binding to DNA. Results: RB1 and γ-tubulin proteins moderate each other's expression by binding to their respective gene promoters. Conclusion: Reduction of γ-tubulin protein levels in tumors with nonfunctional RB1 leads to induction of apoptosis. Significance: The RB1/γ-tubulin signal network can be considered as a new target for cancer treatment. In various tumors inactivation of growth control is achieved by interfering with the RB1 signaling pathway. Here, we describe that RB1 and γ-tubulin proteins moderate each other's expression by binding to their respective gene promoters. Simultaneous reduction of RB1 and γ-tubulin protein levels results in an E2F1-dependent up-regulation of apoptotic genes such as caspase 3. We report that in various tumors types, there is an inverse correlation between the expression levels of γ-tubulin and RB1 and that in tumor cell lines with a nonfunctioning RB1, reduction of γ-tubulin protein levels leads to induction of apoptosis. Thus, the RB1/γ-tubulin signal network can be considered as a new target for cancer treatment.
Chemical properties of lipopolysaccharides from spotted fever group rickettsiae and their common antigenicity with lipopolysaccharides from Proteus species

The lipopolysaccharides (LPS) isolated from spotted fever group (SFG) rickettsia strains Thai tick typhus TT-118 and Katayama were characterized by chemical analyses, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, enzyme-linked immunosorbent assay (ELISA), and immunoblotting. These LPS did not contain heptose, but they contained 3-deoxy-D-manno-octulosonic acid (KDO), glucosamine, quinovosamine, phosphate, ribose, an unknown neutral sugar, and palmitic acid. Resolution of the apparent molecular masses of these LPS by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and staining with silver showed ladder-like bands. In an ELISA, convalescent-phase sera from 10 patients with Japanese spotted fever reacted with LPS from the Katayama strain, and 90% (9 of 10) of these sera also reacted with LPS isolated from Proteus vulgaris OX2. Immunoblotting revealed that the sera reacted with the high-molecular-mass bands of LPS from SFG rickettsiae, in addition to those of OX2 LPS. In an ELISA, immunoglobulin M antibodies from these sera reacted with the O-polysaccharide and lipid A portions of LPS from P. vulgaris OX2. The epitopes common to LPS of SFG rickettsiae and P. vulgaris OX2 may be in the O-polysaccharide and lipid A portions.
Phytase-Producing Bacteria from Extreme Regions in Indonesia

In this study, 154 isolates capable of producing extracellular phytate-degrading activity were isolated from four soil samples from volcanic areas in Central Java, Indonesia. Six strains with high phytate-degrading activity were selected for strain identification and characterization of the corresponding phytate-degrading enzyme. Blast analysis of 16S rRNA gene sequences revealed high similarities for all the six isolates to reference sequences belonging to the genusBacillus. Isolates MS5, MC6, D10 and D16 showed 99% sequence identity toB. cereus, while isolate MC8 exhibited 99% sequence identity toB. aryabhatti and D6 99% sequence identity toB. psychrotolerans. The crude extracellular phytase preparations from the isolates showed following optimal conditions for phytate dephosphorylation: pH 4.0 and 50°C (isolate D10), pH 5.0 and 60°C (isolate MC6, and isolate MS5), pH 6.0 and 50°C (isolate D16) and pH 6.0 and 60°C (isolate D6) and pH 6.0 and 40°C (isolate MC8). Zn2+ and Fe3+ strongly inhibited phytate dephosphorylation with all phytase preparations studied. In the presence of Ca2+, an increase in phytase activity of 10-15% was obtained.

Full Professor, Faculté des sciences infirmières, Université Laval, Québec, Canada. Objective: to evaluate the relationship between the behaviors of salt consumption and sociodemographic and clinical variables. Method: sodium consumption was evaluated using the methods: self-reporting (considering 3 different behaviors related to salt consumption), 24hr dietary recall, discretionary salt, food frequency questionnaire, estimation of total sodium intake and 24-hr urinary excretion of sodium (n=108). Results: elevated salt intake according to the different measurements of consumption of the nutrient was associated with the variables: male sex, low level of schooling and monthly income, being Caucasian, and being professionally inactive; and with the clinical variables: elevated Body Mass Index, tensional levels, ventricular hypertrophy and the number of medications used. Conclusion: the data obtained shows a heterogenous association between the different behaviors related to salt consumption and the socio-demographic and clinical variables. This data can be used to optimize the directing of educational activities with a view to reducing salt consumption among hypertensives.
Risk Factors Influencing Smoking Behavior: A Turkish Twin Study

Aim: In this study, we introduce the first twin study in Turkey, focusing on smoking behavior, and laying the foundation to register all twins born in Turkey for research purposes. Using Turkish twins will contribute to our understanding of health problems in the context of cultural differences. Materials and methods: We assessed 309 twin pairs (339 males and 279 females) aged between 15 and 45 years living in the Kırıkkale and Ankara regions of Turkey, and administered a health and lifestyle interview that included questions about smoking status and smoking history. We analyzed the data using descriptive statistics, t-tests, chi-square tests, and bivariate and multivariate clustered logistic regression. In addition, we fit bivariate Structural Equation Models (SEM) to determine contributions of latent genetic and environmental factors to smoking outcomes in this sample. Results: One hundred seventy-eight participants (28.8%) were identified as smokers, smoking every day for a month or longer, of whom 79.2% were males and 20.8% were females. Mean values for number of cigarettes per day and the Fagerstrom Test of Nicotine Dependence (FTND; Fagerstrom, 1978) score were higher in males than in females, and age of onset was earlier in males. There was a significant positive correlation between the FTND score and number of cigarettes smoked per day, and a significant negative correlation between both variables and age at onset of smoking. Our study showed that gender, presence of a smoking twin in the family, age, alcohol use, marital status, daily sports activities, and feeling moody all played a significant role in smoking behavior among twins. The twin analysis suggested that 79.5% of the liability to FTND was influenced by genetic factors and 20.5% by unique environment, while familial resemblance for smoking initiation was best explained by common environmental factors. Conclusions: Marked differences in the prevalence of smoking behavior in men versus women were observed for the Turkish population. Genetic analyses showed that common environmental factors primarily contributed to smoking initiation, while genetic factors explained a greater proportion of variance in liability to nicotine dependence. Our study shows higher heritability estimate of the FTND scores and higher shared environmental influence on smoking initiation for both males and females than reported in previous studies.
