    Issues of cultural interaction and culturally sensitive assessment and treatment of young children have become prominent in recent years for mental health professionals, for reasons having to do with changing demographics, public values, and professional vision. "Culture" refers to the sociocultural adaptation of design for living shared by people as members of a community. Mental health professionals who work with culturally diverse populations need to become culturally self-aware and find abstract and experiential ways to build a useful body of professional knowledge concerning childrearing and discipline practices, health and illness beliefs, communication styles, and expectations about family or professional relations or other group interactions. They also need to learn how to work effectively in intercultural teams, use families as partners and resources, train and work with interpreters, and select and use formal and nonformal assessment procedures in appropriate, culturally sensitive ways.

    Full Text Available Background: Although there is some evidence of the posttraumatic stress disorder (PTSD construct's cross cultural validity, trauma-related disorders may vary across cultures, and the same may be true for treatments that address such conditions. Experienced therapists tailor psychotherapy to each patient's particular situation, to the nature of the patient's psychopathology, to the stage of therapy, and so on. In addition, culture-sensitive psychotherapists try to understand how culture enhances the meaning of their patient's life history, the cultural components of their illness and help-seeking behaviors, as well as their expectations with regard to treatment. We cannot take for granted that all treatment-seeking trauma survivors speak our language or share our cultural values. Therefore, we need to increase our cultural competencies. Methods: The authors of this article are clinicians and/or researchers from across the globe, working with trauma survivors in various settings. Each author focused on one or more specific cultural aspects of working with trauma survivors and highlighted the following aspects. Results: As a result of culture-specific individual and collective meanings linked to trauma and trauma-related disorders survivors may be exposed to (self-stigma in the aftermath of trauma. Patients who are reluctant to talk about their traumatic experiences may instead be willing to write or use other ways of accessing the painful memories such as drawing. In other cultures, community and family cohesion are crucial elements of recovery. While awareness of culture-specific aspects is important, we also need to beware of premature cultural stereotyping. When disseminating empirically supported psychotherapies for PTSD across cultures, a number of additional challenges need to be taken into account: many low and middle income countries have very limited resources available and suffer from a poor health infrastructure.

    Table etiquette reflects the social-cultural meaning and values of a nation. With the development of China’s opening-up, and more western culture gets into our sights. The dining table is one of the most important places where good manners are displayed. Elegant manners at the table may bring friendship and even success. The different table manners between Chinese and British are the core of this thesis. By comparison of table manners between China and Britain, the thesis aims to make a research on the cultural differences in seating arrangement, using tableware, serving order, dining atmosphere and toasting. Furthermore, this paper displays some taboos of table manners in Chinese and British dinners, which helps a better understanding of the customs.Also,the author collected some business etiquette used in real commercial field and do a lot of investigations. With the comparative research into cultural contrast of table manners in China and Britain, I suggest that you should combine the theory and practice of table manners, understand each cultural background clearly and deeply. Therefore, we can take a better utilization of table manners in social communication and commercial affairs. I hope this paper can help people achieve a successful cross-cultural communication.

    The effects of alkaloid caffeine on insulin sensitivity have been investigated primarily in men, and with a single caffeine dose most commonly of 5-6 mg·kg(-1) of body weight (BW). It is unknown if the effects of caffeine on glucose homeostasis are sex-specific and (or) dose-dependent. This study examined whether caffeine ingestion would disrupt glucose homeostasis in a dose-dependent or threshold manner. It also examined whether sex-specific responses to caffeine exist. It was hypothesized that women would have an exaggerated response to caffeine, and that caffeine would only impair glucose metabolism once a threshold was reached. Twenty-four healthy volunteers (12 males, 12 females) participated in 4 trials, in a crossover, randomized, and double-blind fashion. They ingested caffeine (1, 3, or 5 mg·kg(-1) of BW) or placebo followed, 1 h later, by a 2-h oral glucose tolerance test. Glucose, insulin, C-peptide area under the curve (AUC), and insulin sensitivity index data were fitted to a segmented linear model to determine dose-responses. There were no differences between sexes for any endpoints. Regression slopes were significantly different from zero (p fashion beginning at very low doses (0-1 mg·kg(-1) BW) in both healthy men and women.

    Steroid insensitivity is commonly observed in patients with chronic obstructive pulmonary disease. Here, we report the effects and mechanisms of carbocysteine (S-CMC), a mucolytic agent, in cellular and animal models of oxidative stress-mediated steroid insensitivity. The following results were obtained: oxidative stress induced higher levels of interleukin-8 (IL-8) and tumor necrosis factor alpha (TNF-α), which are insensitive to dexamethasone (DEX). The failure of DEX was improved by the addition of S-CMC by increasing histone deacetylase 2 (HDAC2) expression/activity. S-CMC also counteracted the oxidative stress-induced increase in reactive oxygen species (ROS) levels and decreases in glutathione (GSH) levels and superoxide dismutase (SOD) activity. Moreover, oxidative stress-induced events were decreased by the thiol-reducing agent dithiothreitol (DTT), enhanced by the thiol-oxidizing agent diamide, and the ability of DEX was strengthened by DTT. In addition, the oxidative stress-induced decrease in HDAC2 activity was counteracted by S-CMC by increasing thiol/GSH levels, which exhibited a direct interaction with HDAC2. S-CMC treatment increased HDAC2 recruitment and suppressed H4 acetylation of the IL-8 promoter, and this effect was further ablated by addition of buthionine sulfoximine, a specific inhibitor of GSH synthesis. Our results indicate that S-CMC restored steroid sensitivity by increasing HDAC2 expression/activity in a thiol/GSH-dependent manner and suggest that S-CMC may be useful in a combination therapy with glucocorticoids for treatment of steroid-insensitive pulmonary diseases.

    2016-02-01

    Cross-cultural differences in pain sensitivity have been identified in pain-free subjects as well as in chronic pain patients. The aim was to assess the impact of culture on psychophysical measures using mechanical and electrical stimuli in patients with temporomandibular disorder (TMD) pain and pain-free matched controls in three cultures. This case-control study compared 122 female cases of chronic TMD pain (39 Saudis, 41 Swedes and 42 Italians) with equal numbers of age- and gender-matched TMD-free controls. Pressure pain threshold (PPT) and tolerance (PPTo) were measured over one hand and two masticatory muscles. Electrical perception threshold and electrical pain threshold (EPT) and tolerance (EPTo) were recorded between the thumb and index fingers. Italian females reported significantly lower PPT in the masseter muscle than other cultures (P cultures (P = 0.017). Italians reported significantly lower PPTo in all muscles than Swedes (P ≤ 0.006) and in the masseter muscle than Saudis (P cultures (P = 0.01). Temporomandibular disorder cases, compared to TMD-free controls, reported lower PPT and PPTo in all the three muscles (P cultural differences between groups in the PPT, PPTo and EPTo. Overall, Italian females reported the highest sensitivity to both mechanical and electrical stimulation, while Swedes reported the lowest sensitivity. Mechanical pain thresholds differed more across cultures than did electrical pain thresholds. Cultural factors may influence response to type of pain test.

    The effects of the bioactive polyacetylenes, falcarinol and falcarindiol, present in carrots, celery, celeriac and other umbelliferous vegetables, on the stress responses in primary myotube cultures, were studied. Biphasic responses on cellular stress responses in myotube cultures were investigated by exposing them to various concentrations of falcarinol and falcarindiol for 24 h before testing effects of 100 microM H(2)O(2) on the intracellular formation of reactive oxygen species (ROS), transcription of the antioxidative enzyme cytosolic glutathione peroxidase (cGPx), and the heat shock proteins (HSP) HSP70 and HO1. At low concentrations (1.6 to 25 microM) polyacetylenes caused a slightly accelerated intra-cellular ROS formation, increased cGPx transcription and decreased HSP70 and HO1 transcription. The increased cGPx transcription may be interpreted as an adaptive response to the increased ROS formation and may have caused a reduced demand for the protective functions of the HSPs. ROS formation, however, was substantially decreased after pre-incubation with both polyacetylenes at 50 and 100 microM, the cGPx transcription was reduced and the HSP70 and HO1 transcription increased, indicating a need for the protective and repairing functions of the HSPs. In conclusion, pre-incubation with low concentrations of both polyacetylenes prior to H(2)O(2) exposure induced a cytoprotective effect whereas higher concentrations had adverse effects.

    2017-01-01

    Objectives Inappropriate discipline such as harsh physical punishment is a social determinant of health. The objective was to determine if a brief parent training intervention that teaches discipline strategies is culturally sensitive. Methods English or Spanish-speaking parents of 1-5 year old children viewed a multimedia program that teaches appropriate discipline strategies. The intervention, Play Nicely, was viewed in the exam room before the physician's visit. Parents viewed 4 of 20 discipline strategies of their choosing; the average viewing time was 7 min. Results Of 204 parents eligible to participate, 197 (96 %) completed the study; 41 % were Black, 31 % were White, and 21 % were Hispanic. At least 80 % of parents from each racial/ethnic group reported that the program built their confidence to care for their child, addressed their family needs, explained things in a way they could understand, respected their family values, and was sensitive to their personal beliefs. Overall, 80 % of parents reported that the program answered individual questions. One parent (0.5 %) reported that the program did not respect her family values. Conclusions for Practice Discipline education can be integrated into the pediatric primary care clinic in a way that is family-centered and culturally sensitive for the majority of parents. The results have implications for the development and implementation of population-based parenting programs and the primary prevention of child abuse and violence.

    Baty, Bonnie Jeanne; Kinney, Anita Yeomans; Ellis, Sara Marie

    2003-04-15

    The goal of this project was to develop educational materials to communicate genetic health information in a culturally sensitive manner. These materials were designed to communicate information about cancer risk, genetic testing options, and health management options in an African American kindred with a known BRCA1 mutation. Educational materials were pilot-tested in four African American focus groups varying in socioeconomic status and gender. The audiotaped focus groups consisted of presentation of the educational materials, followed by a feedback session led by an African American facilitator. Qualitative analysis of the focus group transcripts identified important themes and the educational materials were revised in response to the participants' suggestions. The products included a booklet and a flip chart for use in educational sessions. Focus group participants recommended a substantial reduction in technical detail, and recommended that information be personalized and made relevant to the lives of the target population. Other critical themes included the importance of building trust in the medical system and avoiding words and images that have strong negative associations in the African American community. Strategies that were successful included nontechnical images to explain genetic concepts, clip art images to energize and personalize word slides, vibrant color, identifiably African American figures, and the development of themes relevant to many African Americans. The use of these materials in an ongoing study offering BRCA1 counseling and testing to a large, rural Louisiana-based kindred will provide additional feedback about the effectiveness of the culturally tailored genetic education and counseling materials.

    Chen, Shu-Heng; Liou, Wen-Ching; Chen, Ting-Yu

    The global financial crisis brought a serious collapse involving a "systemic" meltdown. Internet technology and globalization have increased the chances for interaction between countries and people. The global economy has become more complex than ever before. Mark Buchanan [12] indicated that agent-based computer models will prevent another financial crisis and has been particularly influential in contributing insights. There are two reasons why culture-sensitive agent on the financial market has become so important. Therefore, the aim of this article is to establish a culture-sensitive agent and forecast the process of change regarding herding behavior in the financial market. We based our study on the Kirman's Ant Model[4,5] and Hofstede's Natational Culture[11] to establish our culture-sensitive agent based model. Kirman's Ant Model is quite famous and describes financial market herding behavior from the expectations of the future of financial investors. Hofstede's cultural consequence used the staff of IBM in 72 different countries to understand the cultural difference. As a result, this paper focuses on one of the five dimensions of culture from Hofstede: individualism versus collectivism and creates a culture-sensitive agent and predicts the process of change regarding herding behavior in the financial market. To conclude, this study will be of importance in explaining the herding behavior with cultural factors, as well as in providing researchers with a clearer understanding of how herding beliefs of people about different cultures relate to their finance market strategies.

    2013-01-01

    Full Text Available Abstract Background Risk for obesity differs with ethnicity/race and is associated with insulin sensitivity (SI, insulin responsiveness, and dietary glycemic load (GL. The objective of this study was to test the hypotheses that, 1 obesity-prone, normal weight, African-American (AA women would be more insulin sensitive than BMI-matched, never overweight AA women; 2 increased adiposity over time would be associated with greater baseline SI and higher dietary GL in AA but not European-American (EA women; and 3 increased adiposity over time would be predicted by SI in women with high but not low acute insulin response to glucose (AIRg. Methods Two controlled weight loss interventions were conducted involving overweight (BMI 25.0-29.9 kg/m2 premenopausal AA and EA women. The first included matching with normal-weight (BMI 2 controls following weight loss, and then comparing SI. The second included a 1-year follow-up of weight-reduced participants to identify predictors of change in %body fat. Main outcome measure in the first study was insulin sensitivity (SI as assessed with intravenous glucose tolerance test (IVGTT, and in the second study was change in %fat, as assessed with DXA, over one year. AIRg was assessed during IVGTT, and free-living diet was determined by food record. Results In the first study, formerly overweight AA women were 43% more insulin sensitive than BMI-matched never overweight AA (P I was positively associated with change in %fat over 1 year only in AA women (P P P = 0.086 for diet x SI interaction. In both studies, AA women had higher AIRg (P  Conclusions Formerly overweight (obesity-prone AA women were more insulin sensitive than never overweight AA women, a quality that may predispose to adiposity, particularly when combined with a high GL diet. This ethnicity/race-specific effect may be due to high insulin responsiveness among AA.

    Isolation of Streptococcus pneumoniae is jeopardized by low sensitivity of blood culture, autolysis and contamination with fast-growing organism(s). We performed an immunochromatographic (ICT) test for S. pneumoniae on chocolatized blood culture bottles and also sub-cultured contaminated bottles on a selective medium, thus identifying an additional eight and three cases, respectively, and improving the detection of pneumococcus by 23% (48% vs. 59%). Prescreening of culture bottles in a blinded fashion could rationalize the use of ICT with ~99% accuracy. These two approaches can aid microbiology laboratories in resource-poor countries to substantially improve rates of detection of S. pneumoniae.

    1997-09-12

    The alpha7 nicotinic receptor agonist 3-[2,4-dimethoxybenzylidene]anabaseine (DMXB; GTS-21) was investigated for its ability to: (1) activate a variety of nicotinic receptor subtypes in Xenopus oocytes; (2) improve passive avoidance and spatial Morris water task performances in mecamylamine-sensitive manners in bilaterally nucleus basalis lesioned rats; and (3) elevate high-affinity [3H]acetylcholine (ACh) and high-affinity alpha-[125I]bungarotoxin binding in rat neocortex following 2 weeks of daily injections. DMXB (100 microM) activated alpha7 homo-oligomeric receptors, without significant activity at alpha2-, alpha3- and alpha4-containing subtypes. Mecamylamine blocked rat alpha7 receptors weakly if co-administered with agonist, but much more potently when pre-applied. Bilateral ibotenic acid lesions of the nucleus basalis interfered with passive avoidance and spatial memory-related behaviors. DMXB (0.5 mg/kg, i.p.) improved passive avoidance behavior in lesioned animals in a mecamylamine-sensitive manner. DMXB (0.5 mg/kg 15 min before each session) also improved performance in the training and probe components of the Morris water task. DMXB-induced improvement in the probe component but not the training phase was mecamylamine-sensitive. [3H]ACh binding was elevated after 14 days of daily i.p. injections with 0.2 mg/kg nicotine but not after 1 mg/kg DMXB. Neither drug elevated high-affinity alpha-[125I]bungarorotoxin binding over this interval.

    Full Text Available This intended to analyze differences in the level of perception –of general population participants- in regards to leaders with diverse socio-cultural characteristics (gender, sexual orientation, religious affiliation, nationality and also verify by means of structural equations, the influence of intergroup anxiety and the cultural sensitivity in terms of the level of effectiveness perception. Participants: 481 adults from Argentina (52.8% female, 47.2% male; age average = 35.45 years old. Instruments: Intergroup Anxiety scale, Cultural Sensitivity scale, and an ad hoc protocol designed to assess level of effectiveness perception in socio-culturally diverse leaders. Results: Differences in the level of perception of effectiveness according to sociocultural characteristics could not be confirmed. However, a direct effect of cultural sensitivity and an indirect effect of intergroup anxiety on the levels of effectiveness perception were confirmed. This work contributes to previous studies on prejudice and leadership.

    Full Text Available Person-centeredness is a goal in diabetes education, and cultural influences are important to consider in this regard. This report describes the use of a design-based research approach to develop culturally sensitive dialog tools to support person-centered dietary education targeting Pakistani immigrants in Denmark with type 2 diabetes. The approach appears to be a promising method to develop dialog tools for patient education that are culturally sensitive, thereby increasing their acceptability among ethnic minority groups. The process also emphasizes the importance of adequate training and competencies in the application of dialog tools and of alignment between researchers and health care professionals with regards to the educational philosophy underlying their use.

    The intentional damages to local Cultural Heritage sites carried out in recent months by the Islamic State (IS) have received wide coverage from the media worldwide. Earth Observation data is an important tool to assess these damages in such non-accessible areas: If a fast response is desired, automated image processing techniques would be needed to speed up the analysis. This paper shows the first results of applying fast and robust change detection techniques to sensitive areas. A map highlighting potentially damaged buildings is derived, which could help experts at timely assessing the damages to the Cultural Heritage sites in the observed images.

    2015-10-01

    This exploratory research examined adjustment challenges, resiliencies, attitudes, emotional health, economic stability, criminal involvement, victimization and service experiences, and some cultural propensities of Greek Immigrants (GIs) in Australia using a convenient multi-generational sample (n = 123; response rate = .5). Data were collected via surveys, telephone, and personal-interviews in four major Australian cities. Among other things, the study revealed that Greek identity and cultural customs are often significant to first generation GIs. Adjustment challenges upon entry include primarily language, housing, and transportation difficulties, nostalgia for relatives and the motherland, unfamiliarity with socio-cultural systems, unemployment, money challenges, and lack of friendships. Christian faith, the extended family, family values and traditions, cultural pride for ancient Greek achievements, and a hard 'work ethic' are notable resiliencies that support GIs in their struggles and solidify their pursuit for happiness and success. Financial concerns, aging, and nostalgia for relatives and the motherland were the primary causes of socio-emotional instability. Attitudinal differences in the respondents based on age, gender, and socio-economic status, cross-cultural comparisons, and recommendations for culturally-sensitive practice with GIs are analyzed and methodological limitations illuminated. Future research needs in the field are also highlighted.

    Personnel from diverse ethnic and demographic backgrounds come together in both civilian and military healthcare systems, facing diagnoses that at one level are equalizers: coronary disease is coronary disease, breast cancer is breast cancer. Yet the expression of disease in individuals from different backgrounds, individual patient experience of disease as a particular illness, and interactions between patients and providers occurring in any given disease scenario, all vary enormously depending on the fortuity of the equation of "which patient happens to arrive in whose exam room." Previously, providers' absorption of lessons-learned depended on learning as an apprentice would when exposed over time to multiple populations. As a result, and because providers are often thrown into situations where communications falter through inadequate direct patient experience, diversity in medicine remains a training challenge. The questions then become: Can simulation and virtual training environments (VTEs) be deployed to short-track and standardize this sort of random-walk problem? Can we overcome the unevenness of training caused by some providers obtaining the valuable exposure to diverse populations, whereas others are left to "sink or swim"? This paper summarizes developing a computer-based VTE called TEACH (Training to Enable/Achieve Culturally Sensitive Healthcare). TEACH was developed to enhance healthcare providers' skills in delivering culturally sensitive care to African-American women with breast cancer. With an authoring system under development to ensure extensibility, TEACH allows users to role-play in clinical oncology settings with virtual characters who interact on the basis of different combinations of African American sub-cultural beliefs regarding breast cancer. The paper reports on the roll-out and evaluation of the degree to which these interactions allow providers to acquire, practice, and refine culturally appropriate communication skills and to

    2010-06-01

    This study examined the effect of close and extended intercultural contact on attributions for behaviour of out-group members. Specifically, it was hypothesized that extended intercultural contact would enhance the ability to make external and culturally sensitive attributions for ambiguous behaviour of out-group members, while decreasing the common tendency to overestimate internal factors. A content analysis of open-ended attributions supported these hypotheses, revealing that majority group members in Germany who had hosted an exchange student from another continent used significantly less internal and more external as well as culturally sensitive attributions to explain the behaviour described in critical intercultural incidents, compared to future hosts. The effect remained significant when controlling for perspective taking and prior intercultural experience. Moreover, the hypothesis was supported for scenarios describing different cultural groups (regardless of the exchange students' country of origin), suggesting a generalized effect. Problems of selection bias are discussed, and the importance of studying a range of positive outcomes of intercultural contact is emphasized.

    It has been shown that exposure to radiation of LED sources of light with an emission band maximum at about 465 and 520 nm having substantially identical damaging effects on animal cells in culture, that are in a logarithmic growth phase and preincubated with pigment. Photobiological effect is caused by photodynamic processes involving singlet oxygen generated by triplet excited sensitizer. Mono-exponential type dependence of cell survival on the energy dose indicates that it is bilirubin that acts as a sensitizer but not its photoproducts. The inclusion of bilirubin in the cells, where it is primarily localized in the mitochondria cells, it is accompanied by multiple amplification photochemical stability compared to pigment molecules bound with albumin

  7. Nef alleles from all major HIV-1 clades activate Src-family kinases and enhance HIV-1 replication in an inhibitor-sensitive manner.

    Purushottam S Narute

    Full Text Available The HIV-1 accessory factor Nef is essential for high-titer viral replication and AIDS progression. Nef function requires interaction with many host cell proteins, including specific members of the Src kinase family. Here we explored whether Src-family kinase activation is a conserved property of Nef alleles from a wide range of primary HIV-1 isolates and their sensitivity to selective pharmacological inhibitors. Representative Nef proteins from the major HIV-1 subtypes A1, A2, B, C, F1, F2, G, H, J and K strongly activated Hck and Lyn as well as c-Src to a lesser extent, demonstrating for the first time that Src-family kinase activation is a highly conserved property of primary M-group HIV-1 Nef isolates. Recently, we identified 4-amino substituted diphenylfuropyrimidines (DFPs that selectively inhibit Nef-dependent activation of Src-family kinases as well as HIV replication. To determine whether DFP compounds exhibit broad-spectrum Nef-dependent antiretroviral activity against HIV-1, we first constructed chimeric forms of the HIV-1 strain NL4-3 expressing each of the primary Nef alleles. The infectivity and replication of these Nef chimeras was indistinguishable from that of wild-type virus in two distinct cell lines (U87MG astroglial cells and CEM-T4 lymphoblasts. Importantly, the 4-aminopropanol and 4-aminobutanol derivatives of DFP potently inhibited the replication of all chimeric forms of HIV-1 in both U87MG and CEM-T4 cells in a Nef-dependent manner. The antiretroviral effects of these compounds correlated with inhibition of Nef-dependent activation of endogenous Src-family kinases in the HIV-infected cells. Our results demonstrate that the activation of Hck, Lyn and c-Src by Nef is highly conserved among all major clades of HIV-1 and that selective targeting of this pathway uniformly inhibits HIV-1 replication.

  8. Culture-bound syndrome and a culturally sensitive approach: from a viewpoint of medical anthropology.

    Shimoji, A; Miyakawa, T

    2000-08-01

    Some aspects of the culture-bound syndrome are presented for discussion. From the psychiatric and medical anthropological viewpoints, kamidaari is described as an initiatory illness for seeing a shaman, and focus on clinical realities developing between different therapeutic subcultures in the same culture and the complementary practices of two epistemological ones, namely, the shamanistic and modern psychiatric system in the shamanistic climate. It is suggested that the culture-bound syndrome that reflects cultural influences on disease patterns and renders them difficult to place in a universal classificatory system should be seen as a vernacular bricolage or as tactics used by people within the web of their own local culture of origin. Therapists who treat patients in a cross-epistemological milieu should be aware of the subcultural-epistemological issues that may affect the clinical process. It should be recognized that, depending on the nature of a particular psychiatric crisis, the clinical encounter is straddling the boundaries of multiple clinical realities. At every stage in the clinical field, there is an intersection, consonance, or interruption of rejoinders in the open dialog by all those engaged in the clinical time. Aspects of climatic, culturally sensitive psychotherapy will be described, and the concept of the culture-bound syndrome will be reconsidered. Our approach could be seen as 'situation- and fudo-bound'.

    American Indians and Alaska Natives (AI/ANs) have a unique, traumatic, and alienating history of education in the U.S., which may be directly related to overall health and well-being. Community engagement is critical in well-being research with Native communities, especially when investigating culturally sensitive topics, such as early education experiences. This study investigates the value of a community-based participatory research approach in gaining valuable culturally sensitive information from Native people in a respectful manner. Assessment participation and feedback are analyzed and presented as indicators of Native participant engagement success in a potentially sensitive research project exploring early education experiences.

    Full Text Available This paper discusses the perceptions of Egyptian minority groups in relation to internet information technology with which they feel empowered to protect, affirm and communicate their oppressed existence, on local and global dimensions. The research employs qualitative methods and interpretive analysis, to focus on the use of Internet information technology tools by Egyptian minority groups, in particular, their online platforms and chat rooms, and the related issues associated with these practices and usages. The paper argues that cyberspace is used by specific minority groups in Egypt as a "gateway to freedom" in which it constitutes an ally to establish newly founded cyber identities that aide them to exercise their basic human rights of freedom of thought, speech and expression. The paper thus examines cyberspace a medium or tool for the carrying out of information exchange without the traditional fear of politics and power that is deeply engraved in the roots of the Egyptian culture. In this way, these minority groups are analysed as the newly conceived human information systems (HIS residing on Internet information technology and infrastructure. The paper proposes an adaptive and culturally sensitive model of human information systems as well as human information systems development life cycle (HISDLC to aid in establishing effective processes of information exchange and creation, hence assisting in the emancipation of conflicting parties residing in Egypt, elsewhere in the Middle East and globally.

    Several chemicals have been widely used to evaluate the involvement of free Ca(2+) in mechanisms underlying a variety of biological responses for decades. Here, we report high reactivity to zinc of well-known Ca(2+)-sensitive reagents in diverse cultured cells. In rat astrocytic C6 glioma cells loaded with the fluorescent Ca(2+) dye Fluo-3, the addition of ZnCl2 gradually increased the fluorescence intensity in a manner sensitive to the Ca(2+) chelator EGTA irrespective of added CaCl2. The addition of the Ca(2+) ionophore A23187 drastically increased Fluo-3 fluorescence in the absence of ZnCl2, while the addition of the Zn(2+) ionophore pyrithione rapidly and additionally increased the fluorescence in the presence of ZnCl2, but not in its absence. In cells loaded with the zinc dye FluoZin-3 along with Fluo-3, a similarly gradual increase was seen in the fluorescence of Fluo-3, but not of FluoZin-3, in the presence of both CaCl2 and ZnCl2. Further addition of pyrithione drastically increased the fluorescence intensity of both dyes, while the addition of the Zn(2+) chelator N,N,N',N'-tetrakis(2-pyridylmethyl)ethane-1,2-diamine (TPEN) rapidly and drastically decreased FluoZin-3 fluorescence. In cells loaded with FluoZin-3 alone, the addition of ZnCl2 induced a gradual increase in the fluorescence in a fashion independent of added CaCl2 but sensitive to EGTA. Significant inhibition was found in the vitality to reduce 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide in a manner sensitive to TPEN, EDTA and BAPTA in C6 glioma cells exposed to ZnCl2, with pyrithione accelerating the inhibition. Similar inhibition occurred in an EGTA-sensitive fashion after brief exposure to ZnCl2 in pluripotent P19 cells, neuronal Neuro2A cells and microglial BV2 cells, which all expressed mRNA for particular zinc transporters. Taken together, comprehensive analysis is absolutely required for the demonstration of a variety of physiological and pathological responses

    Scholes, J; Moore, D

    2000-03-01

    This paper reports on a clinical exchange programme that formed part of a pre-registration European nursing degree run by three collaborating institutions in England, Holland and Spain. The course included: common and shared learning including two summer schools; and the development of a second language before the students went on a three-month clinical placement in one of the other base institutions' clinical environments. The aim of the course was to enable students to become culturally sensitive carers. This was achieved by developing a programme based on transcultural nursing principles in theory and practice. Data were gathered by interview, focus groups, and questionnaires from 79 exchange students, fostering the strategies of illuminative evaluation. The paper examines: how the aims of the course were met; the factors that inhibited the attainment of certain goals; and how the acquisition of a second language influenced the students' learning about nursing. A model is presented to illustrate the process of transformative learning from the exchange experience.

    2016-11-01

    Midwifery educators and regulators in Canada have begun to address diversity, equity, and inclusion in admission processes and program curricula. Populations served by midwives value internationally educated midwives from their countries of origin. The International Midwifery Pre-Registration Program at Ryerson University in Toronto, Ontario, provides assessment, midwifery workplace orientation, and accelerated education for internationally educated midwives on behalf of the regulatory College of Midwives of Ontario. Between 2003 and 2015, midwives from 41 countries participated in the bridging program, and 214 (80%) successfully completed the program and qualified for licensure. Of these 214 graduates, 100% passed the Canadian Midwifery Registration Examination and 193 (90%) were employed full time as midwives within 4 months of graduation. The program curriculum enables the integration of these midwives into health care workplaces utilizing innovative approaches to assessment and competency enhancement. Critical to the bridging process are simulation-based practices to develop effective psychomotor learning, virtual and real primary care community placements, and coaching in empathetic, client-centered communication. Cultural sensitivity is embedded into the multiple assessment and learning modalities, and addresses relevant barriers faced by immigrant midwives in the workplace. Findings from the 13 years of the program may be applicable to increase diversity in other North American midwifery settings. This article describes the process, content, outcomes, and findings of the program. Midwifery educators and regulators may consider the utility of these approaches for their settings. © 2016 by the American College of Nurse-Midwives.

    Ruddock, Heidi C; Turner, de Sales

    2007-08-01

    This paper is a report of a study to explore whether having an international learning experience as part of a nursing education programme promoted cultural sensitivity in nursing students. background: Many countries are becoming culturally diverse, but healthcare systems and nursing education often remain mono-cultural and focused on the norms and needs of the majority culture. To meet the needs of all members of multicultural societies, nurses need to develop cultural sensitivity and incorporate this into caregiving. A Gadamerian hermeneutic phenomenological approach was adopted. Data were collected in 2004 by using in-depth conversational interviews and analysed using the Turner method. Developing cultural sensitivity involves a complex interplay between becoming comfortable with the experience of making a transition from one culture to another, making adjustments to cultural differences, and growing personally. Central to this process was the students' experience of studying in an unfamiliar environment, experiencing stress and varying degrees of culture shock, and making a decision to take on the ways of the host culture. These actions led to an understanding that being sensitive to another culture required being open to its dynamics, acknowledging social and political structures, and incorporating other people's beliefs about health and illness. The findings suggest that study abroad is a useful strategy for bridging the theory-practice divide. However, further research is needed with larger and more diverse students to test the generalizability of the findings. Longitudinal research is also needed to assess the impact of study abroad programmes on the deliver of culturally sensitive care.

    Wide variations exist among perinatal hospices, and barriers to perinatal palliative care exist at the healthcare level. Research in the area of culturally sensitive perinatal palliative care has been scarce, a gap which this study addresses. To evaluate the relationship between the nurse work environment and the delivery of culturally sensitive perinatal hospice care. This retrospective, correlational study used data from the National Home and Hospice Care Survey, which includes a nationally representative sample of hospice care providers. A multivariate logistic regression model was used to estimate the relationship between the delivery of culturally sensitive care and the nurse work environment. Accreditation, teaching status, and baccalaureate-prepared registered nurse staff had an impact on the provision of culturally sensitive perinatal care Conclusions: The hospice and nursing unit environments, specifically in regards to education and technology, may be important contributors to the delivery of culturally sensitive care.

    Full Text Available Administrator and staff perceptions (N = 72 of alcohol, tobacco, and other drugs (ATOD agency cultural sensitivity were explored in a predominantly Hispanic rural area with elevated levels of acculturation and high ATOD usage. While providers generally agreed that a relatively moderate need existed for training related to cultural issues, a more nuanced picture emerged in the purview of culturally- related barriers. Administrators viewed the lack of appropriate interpreters and language as a greater barrier than did the staff. Administrators also held higher perceptions of agencies’ cultural competency. The overall high assessment of cultural sensitivity may result from the substantial number of Latino providers.

    To determine the relationship between cultural sensitivity and perceived stress of nurses working at Kilis State Hospital. As foreigners live in and visit Turkey for various reasons, it is essential to provide culturally appropriate healthcare. Descriptive and cross-sectional design. This study was implemented at the State Hospital in Kilis on the southeast border of Turkey, between June-July 2014. The study sample consisted of 120 nurses. Data collection tools included a questionnaire about the socio-demographic and professional characteristics of participants, the Chen and Starosta's Intercultural Sensitivity Scale, and Perceived Stress Scale. The average score for nurse cultural sensitivity was 84·32 (SD, 11·40) and the average score for perceived stress was 27·97 (SD, 7·32), corresponding to a medium level. We identified negative correlation between cultural sensitivity and perceived stress. Nurses working at Kilis State Hospital have a medium level of cultural sensitivity and perceived stress, and cultural sensitivity tended to be affected by perceived stress. This study suggests that training programmes for cultural sensitivity and stress management should be available for nurses. Furthermore, patient care plans should be adapted to consider different cultural backgrounds of patients. These findings should be considered when designing nurses' education and continuing education programmes. © 2015 John Wiley & Sons Ltd.

    From germinating pollen of lily, two types of villins, P-115-ABP and P-135-ABP, have been identified biochemically. Ca(2+)-CaM-dependent actin-filament binding and bundling activities have been demonstrated for both villins previously. Here, we examined the effects of lily villins on the polymerization and depolymerization of actin. P-115-ABP and P-135-ABP present in a crude protein extract prepared from germinating pollen bound to a DNase I affinity column in a Ca(2+)-dependent manner. Purified P-135-ABP reduced the lag period that precedes actin filament polymerization from monomers in the presence of either Ca(2+) or Ca(2+)-CaM. These results indicated that P-135-ABP can form a complex with G-actin in the presence of Ca(2+) and this complex acts as a nucleus for polymerization of actin filaments. However, the nucleation activity of P-135-ABP is probably not relevant in vivo because the assembly of G-actin saturated with profilin, a situation that mimics conditions found in pollen, was not accelerated in the presence of P-135-ABP. P-135-ABP also enhanced the depolymerization of actin filaments during dilution-mediated disassembly. Growth from filament barbed ends in the presence of Ca(2+)-CaM was also prevented, consistent with filament capping activity. These results suggested that lily villin is involved not only in the arrangement of actin filaments into bundles in the basal and shank region of the pollen tube, but also in regulating and modulating actin dynamics through its capping and depolymerization (or fragmentation) activities in the apical region of the pollen tube, where there is a relatively high concentration of Ca(2+).

    The effect of cold temperature on arthritis symptoms is unclear. The aim of this study was to investigate how environmental cold affects pain and blood flow in mono-arthritic mice, and examine a role for transient receptor potential ankyrin 1 (TRPA1), a ligand-gated cation channel that can act as a cold sensor. Mono-arthritis was induced by unilateral intra-articular injection of complete Freund's adjuvant (CFA) in CD1 mice, and in mice either lacking TRPA1 (TRPA1 KO) or respective wildtypes (WT). Two weeks later, nociception and joint blood flow were measured following exposure to 10 °C (1 h) or room temperature (RT). Primary mechanical hyperalgesia in the knee was measured by pressure application apparatus; secondary mechanical hyperalgesia by automated von Frey system; thermal hyperalgesia by Hargreaves technique, and weight bearing by the incapacitance test. Joint blood flow was recorded by full-field laser perfusion imager (FLPI) and using clearance of (99m)Technetium. Blood flow was assessed after pretreatment with antagonists of either TRPA1 (HC-030031), substance P neurokinin 1 (NK1) receptors (SR140333) or calcitonin gene-related peptide (CGRP) (CGRP8-37). TRPA1, TAC-1 and CGRP mRNA levels were examined in dorsal root ganglia, synovial membrane and patellar cartilage samples. Cold exposure caused bilateral primary mechanical hyperalgesia 2 weeks after CFA injection, in a TRPA1-dependent manner. In animals maintained at RT, clearance techniques and FLPI showed that CFA-treated joints exhibited lower blood flow than saline-treated joints. In cold-exposed animals, this reduction in blood flow disappears, and increased blood flow in the CFA-treated joint is observed using FLPI. Cold-induced increased blood flow in CFA-treated joints was blocked by HC-030031 and not observed in TRPA1 KOs. Cold exposure increased TRPA1 mRNA levels in patellar cartilage, whilst reducing it in synovial membranes from CFA-treated joints. We provide evidence that environmental

    There is a need for rapid, efficient and cost-effective alternatives to traditional in vivo developmental neurotoxicity testing. In vitro cell culture models can recapitulate many of the key cellular processes of nervous system development, including neurite outgrowth, and may be used as screening tools to identify potential developmental neurotoxicants. The present study compared primary rat cortical cultures and human embryonic stem cell-derived neural cultures in terms of: 1) reproducibility of high content image analysis based neurite outgrowth measurements, 2) dynamic range of neurite outgrowth measurements and 3) sensitivity to chemicals which have been shown to inhibit neurite outgrowth. There was a large increase in neurite outgrowth between 2 and 24 h in both rat and human cultures. Image analysis data collected across multiple cultures demonstrated that neurite outgrowth measurements in rat cortical cultures were more reproducible and had higher dynamic range as compared to human neural cultures. Human neural cultures were more sensitive than rat cortical cultures to chemicals previously shown to inhibit neurite outgrowth. Parallel analysis of morphological (neurite count, neurite length) and cytotoxicity (neurons per field) measurements were used to detect selective effects on neurite outgrowth. All chemicals which inhibited neurite outgrowth in rat cortical cultures did so at concentrations which did not concurrently affect the number of neurons per field, indicating selective effects on neurite outgrowth. In contrast, more than half the chemicals which inhibited neurite outgrowth in human neural cultures did so at concentrations which concurrently decreased the number of neurons per field, indicating that effects on neurite outgrowth were secondary to cytotoxicity. Overall, these data demonstrate that the culture models performed differently in terms of reproducibility, dynamic range and sensitivity to neurite outgrowth inhibitors. While human neural

    OBJECTIVE To assess Spanish-speaking patients' satisfaction with their clinical pharmacists' communication skills and demonstration of cultural sensitivity, while controlling for patients' sociodemographic, clinical, and communication factors, as well as pharmacist factors, and to identify clinical pharmacists' cultural factors that are important to Spanish-speaking patients. DESIGN Cross-sectional study. SETTING Central Texas during August 2011 to May 2012. PARTICIPANTS Spanish-speaking patients of federally qualified health centers (FQHCs). MAIN OUTCOME MEASURE(S) A Spanish-translated survey assessed Spanish-speaking patients' satisfaction with their clinical pharmacists' communication skills and demonstration of cultural sensitivity. RESULTS Spanish-speaking patients (N = 101) reported overall satisfaction with their clinical pharmacists' communication skills and cultural sensitivity. Patients also indicated that pharmacists' cultural rapport (e.g., ability to speak Spanish, respectfulness) was generally important to Spanish speakers. Multiple linear regression analyses showed that cultural rapport was significantly related to satisfaction with pharmacists' communication skills and demonstration of cultural sensitivity. CONCLUSION Overall, patients were satisfied with pharmacists' communication skills and cultural sensitivity. Patient satisfaction initiatives that include cultural rapport should be developed for pharmacists who provide care to Spanish-speaking patients with limited English proficiency.

    The elucidation of the functional mechanisms of extracellular acidification stimulating intracellular signaling pathway is of great importance for developing new targets of treatment for solid tumors, and inflammatory disorders characterized by extracellular acidification. In the present study, we focus on the regulation of extracellular acidification on intracellular signaling pathways in mouse embryo fibroblasts (MEFs). We found extracellular acidification was at least partly involved in stimulating p38MAPK pathway through PTX-sensitive behavior to enhance cell migration in the presence or absence of platelet-derived growth factor (PDGF). Statistical analysis showed that the actions of extracellular acidic pH and PDGF on inducing enhancement of cell migration were not an additive effect. However, we also found extracellular acidic pH did inhibit the viability and proliferation of MEFs, suggesting that extracellular acidification stimulates cell migration probably through proton-sensing mechanisms within MEFs. Using OGR1-, GPR4-, and TDAG8-gene knock out technology, and real-time qPCR, we found known proton-sensing G protein-coupled receptors (GPCRs), transient receptor potential vanilloid subtype 1 (TRPV1), and acid-sensing ion channels (ASICs) were unlikely to be involved in the regulation of acidification on cell migration. In conclusion, our present study validates that extracellular acidification stimulates chemotactic migration of MEFs through activation of p38MAPK with a PTX-sensitive mechanism either by itself, or synergistically with PDGF, which was not regulated by the known proton-sensing GPCRs, TRPV1, or ASICs. Our results suggested that others proton-sensing GPCRs or ion channels might exist in MEFs, which mediates cell migration induced by extracellular acidification in the presence or absence of PDGF. - Highlights: • Acidic pH and PDGF synergize to stimulate MEFs migration via Gi/p38MAPK pathway. • Extracellular acidification inhibits the

    Full Text Available BACKGROUND: Culture remains the diagnostic gold standard for many bacterial infections, and the method against which other tests are often evaluated. Specificity of culture is 100% if the pathogenic organism is not found in healthy subjects, but the sensitivity of culture is more difficult to determine and may be low. Here, we apply Bayesian latent class models (LCMs to data from patients with a single Gram-negative bacterial infection and define the true sensitivity of culture together with the impact of misclassification by culture on the reported accuracy of alternative diagnostic tests. METHODS/PRINCIPAL FINDINGS: Data from published studies describing the application of five diagnostic tests (culture and four serological tests to a patient cohort with suspected melioidosis were re-analysed using several Bayesian LCMs. Sensitivities, specificities, and positive and negative predictive values (PPVs and NPVs were calculated. Of 320 patients with suspected melioidosis, 119 (37% had culture confirmed melioidosis. Using the final model (Bayesian LCM with conditional dependence between serological tests, the sensitivity of culture was estimated to be 60.2%. Prediction accuracy of the final model was assessed using a classification tool to grade patients according to the likelihood of melioidosis, which indicated that an estimated disease prevalence of 61.6% was credible. Estimates of sensitivities, specificities, PPVs and NPVs of four serological tests were significantly different from previously published values in which culture was used as the gold standard. CONCLUSIONS/SIGNIFICANCE: Culture has low sensitivity and low NPV for the diagnosis of melioidosis and is an imperfect gold standard against which to evaluate alternative tests. Models should be used to support the evaluation of diagnostic tests with an imperfect gold standard. It is likely that the poor sensitivity/specificity of culture is not specific for melioidosis, but rather a generic

    Cultural competence is a stated value of nursing and nursing education. However, some institutional and traditional practices in nursing education can unintentionally impede nurses from achieving cultural competence. Both the literature and interviews with nurse educators show that despite educators' intentions to treat all students the same, nontraditional students may feel singled out and may in fact be singled out for closer scrutiny because of their difference from the demographic norms of nursing students. To ensure that the nursing profession reflects the composition of the patient population it serves, nurse educators must first acknowledge the Eurocentric culture of nursing education and, then, work to change the environment in which students are recruited, learn, and take on the role of beginning practicing nurses.

    The human placental GH variant (GH-V) is secreted continuously from the syncytiotrophoblast layer of the placenta during pregnancy and is thought to play a key role in the maternal adaptation to pregnancy. Maternal GH-V concentrations are closely related to fetal growth in humans. GH-V has also been proposed as a potential candidate to mediate insulin resistance observed later in pregnancy. To determine the effect of maternal GH-V administration on maternal and fetal growth and metabolic outcomes during pregnancy, we examined the dose-response relationship for GH-V administration in a mouse model of normal pregnancy. Pregnant C57BL/6J mice were randomized to receive vehicle or GH-V (0.25, 1, 2, or 5 mg/kg · d) by osmotic pump from gestational days 12.5 to 18.5. Fetal linear growth was slightly reduced in the 5 mg/kg dose compared with vehicle and the 0.25 mg/kg groups, respectively, whereas placental weight was not affected. GH-V treatment did not affect maternal body weights or food intake. However, treatment with 5 mg/kg · d significantly increased maternal fasting plasma insulin concentrations with impaired insulin sensitivity observed at day 18.5 as assessed by homeostasis model assessment. At 5 mg/kg · d, there was also an increase in maternal hepatic GH receptor/binding protein (Ghr/Ghbp) and IGF binding protein 3 (Igfbp3) mRNA levels, but GH-V did not alter maternal plasma IGF-1 concentrations or hepatic Igf-1 mRNA expression. Our findings suggest that at higher doses, GH-V treatment can cause hyperinsulinemia and is a likely mediator of the insulin resistance associated with late pregnancy.

    Full Text Available Education is the means by which society provides for the transmission or advancement of its culture and it is formally done at schools that are the arena of human interaction aimed at producing learning. But some people in that interaction aimed at producing learning cannot achieve as much as the others due to some social or individual factors especially when the society is not homogeneous in terms of culture, language, etc.All cultures do not require the same kinds of knowledge and all may have distinct goals and expectations in education. This study aims at presenting the consensus and conflict in perspectives of students of different ethnic origins on general goals of education and expectations from schools in East and Southeast Turkey. The results will be used to generate a rationale to assume that the failure of students in East and Southeast Turkey where majority of population is ethnically diverse, may be because of the lack of divergent goals and expectations set for school curriculum or that the failure of students is dependent on some other factors except the unique school curriculum unresponsive to cultural or ethnic diversity. For this purpose, the goals of general education (1973, Law number 1739, Item number 2, and school expectations developed by House (1973 were prepared as questionnaire items, piloted, validated and administered to 9373 secondary school students in east and southeast Turkey. The findings of this study were that the students of different ethnic origins value the goals and expectations set for school curriculum in Turkey in significantly different ways.

    2016-01-01

    Previous research in cultural psychology shows that cultures vary in the social orientation of independence and interdependence. To date, however, little is known about how people may acquire such global patterns of cultural behavior or cultural norms. Nor is it clear what genetic mechanisms may underlie the acquisition of cultural norms. Here, we draw on recent evidence for certain genetic variability in the susceptibility to environmental influences and propose a norm sensitivity hypothesis, which holds that people acquire culture, and rules of cultural behaviors, through reinforcement-mediated social learning processes. One corollary of the hypothesis is that the degree of cultural acquisition should be influenced by polymorphic variants of genes involved in dopaminergic neural pathways, which have been widely implicated in reinforcement learning. We reviewed initial evidence for this prediction and discussed challenges and directions for future research. PMID:28491931

    Type 2 diabetes affects Chinese Americans at an alarming rate. To address this health disparity, research in the area of cultural sensitivity and health literacy provides useful guidelines for creating culturally appropriate health education. In this article, we use discourse analysis to examine a group of locally available, Chinese- and English-language diabetes print documents from a surface level and deep structure level of culture. First, we compared these documents to research findings about printed health information to determine whether and how these documents apply current best practices for health literacy and culturally appropriate health communication. Second, we examined how diabetes as a disease and diabetes management is being constructed. The printed materials addressed surface level culture through the use of Chinese language, pictures, foods, and exercises. From a deeper cultural level, the materials constructed diabetes management as a matter of measurement and control that contrasted with previous research suggesting an alternative construction of balance. A nuanced assessment of both surface and deeper levels of culture is essential for creating health education materials that are more culturally appropriate and can lead to increased health literacy and improved health outcomes.

    This study explored the methods that are used by public health nurses to provide culturally sensitive health counseling to elderly Japanese farmers in order to motivate them to adopt healthy behaviors. Fourteen elderly farmers (eight men and six women) from three rural communities underwent health counseling and then changed their habits to prevent lifestyle-related diseases. Qualitative and inductive analyses were conducted to determine the effects of the culturally sensitive counseling. Five methods for providing culturally sensitive counseling were identified: (i) showing an interest in, and respect for, the local culture; (ii) stimulating the participants' awareness of the health risks inherited in their local cultural practices through the use of familiar examples; (iii) accepting and understanding the participants' ambivalence about their local culture; (iv) connecting the reasons for the participants to change their lifestyle with their local culture; and (v) adjusting the health-promoting behaviors of the participants to fit their local culture. Public health nurses should consider the pride that elderly farmers have in their background and their resistance to change and use these factors to point out the discrepancies in their lifestyle and promote more quality-of-life-oriented and practical self-care behaviors.

    Stem and precursor cells play an important role in development and regeneration. The state of these cells is regulated by biochemical substances, mechanical stimuli and cellular interactions. To estimate gravity effects we used two types of cultured stem cells: human mesenchymal stromal cells (hMSCs) from bone marrow and mice embryonic stem (mESC) line R1. Gravity changes were simulated by long-term (4-7 days) slow clinorotation and leaded to decreased hMSC proliferation, changes of cell morphology and modified F-actin cytoskeleton. We did not find the shifts in cell phenotype except for decreased expression of HLA 1 and CD105 but excretion of IL-6 into medium increased significantly. Remodeling of cytoskeleton started after first 4 h and was similar to preapoptotic changes. This data suggested the modification in cell adhesion and possible commitment of hMSC. It was observed that expression of alkaline phosphatase by MSC in osteogenic medium was more intensive in control. On the contrary, clinorotation did not change formation of mESC colonies and increased proliferation activity in LIF+-medium. However, the number of embryonic bodies after clinorotation was less than in static control. It is suggested that ESCs kept the viability and proliferative potential but decreased the differentiation ability after changes in gravity stimulation.

    2010-01-01

    There has been a lot of talk in the media about the loss of courtesy in modern society. By many criteria, it seems that people in general have lost a degree of politeness. Reading some of the online comments after several recent articles in The Scientist would seem to indicate that biologists have also lost their manners. This lack of basic manners alarms me not only because of the obvious danger to our sense of community, but also because this type of behavior could damage society’s positive perception of scientists. Every time scientists (or anonymous bloggers posing as scientists) rant about the idiocy of someone who disagrees with them, our collective credibility erodes. Yes, there are a number of issues that we as scientists should be passionate about, but our objectives are best served by retaining an objective demeanor and respecting those to whom we happen to disagree.

    The study critically explored how culture and language sensitive curriculum materials in physics improve Pangasinan learners' attitude towards science. Their cultural dimensions, epistemological beliefs, and views on integration of culture and language in the teaching and learning process determined their cultural preference or profile. Design and development of culture and language sensitive curriculum materials in physics were heavily influenced by these learners' cultural preference or profile. Pilot-study using interviews and focus group discussions with natives of Pangasinan and document analysis were conducted to identify the culture, practices, and traditions integrated in the lesson development. Comparison of experimental participants' pretest and posttest results on science attitude measure showed significant statistical difference. Appraisal of science attitude enhancement favored the experimental group over the control group. Qualitative data deduced from post implementation interviews, focus group discussions, and journal log entries showed the same trend in favor of the experimental participants. The study revealed that culture and language integration in the teaching and learning process of physics concepts enabled students to develop positive attitude to science, their culture, and native language.

    Full Text Available Abstract Background We have established that activation of the tryptophan degrading enzyme indoleamine 2,3 dioxygenase (IDO mediates the switch from cytokine-induced sickness behavior to depressive-like behavior. Because human immunodeficiency virus type 1 (HIV-1 Tat protein causes depressive-like behavior in mice, we investigated its ability to activate IDO in organotypic hippocampal slice cultures (OHSCs derived from neonatal C57BL/6 mice. Methods Depressive-like behavior in C57BL/6J mice was assessed by the forced swim test. Expression of cytokines and IDO mRNA in OHSCs was measured by real-time RT-PCR and cytokine protein was measured by enzyme-linked immunosorbent assays (ELISAs. p38 MAPK phosphorylation was analyzed by western blot. Results Intracerebroventricular (i.c.v. administration of Tat (40 ng induced depressive-like behavior in the absence of sickness. Addition of Tat (40 ng/slice to the medium of OHSCs induced IDO steady-state mRNA that peaked at 6 h. This effect was potentiated by pretreatment with IFNγ. Tat also induced the synthesis and release of TNFα and IL-6 protein in the supernatant of the slices and increased expression of the inducible isoform of nitric oxide synthase (iNOS and the serotonin transporter (SERT. Tat had no effect on endogenous synthesis of IFNγ. To explore the mechanisms of Tat-induced IDO expression, slices were pretreated with the p38 mitogen-activated protein kinase (MAPK inhibitor SB 202190 for 30 min before Tat treatment. SB 202190 significantly decreased IDO expression induced by Tat, and this effect was accompanied by a reduction of Tat-induced expression of TNFα, IL-6, iNOS and SERT. Conclusion These data establish that Tat induces IDO expression via an IFNγ-independent mechanism that depends upon activation of p38 MAPK. Targeting IDO itself or the p38 MAPK signaling pathway could provide a novel therapy for comorbid depressive disorders in HIV-1-infected patients.

    As foreigners live in and visit Turkey for various reasons, it is essential to provide culturally appropriate health care. This study was conducted to determine the relationship between cultural sensitivity and assertiveness in university nursing students. This descriptive, cross-sectional study was conducted at two universities in the cities of Kilis and Elazığ, Turkey. The study sample consisted of 444 nursing students. Data collection tools included a questionnaire about participant sociodemographic characteristics, Chen and Starosta's Intercultural Sensitivity Scale, and the Rathus Assertiveness Scale. The mean age of participants was 21.09 years. Most students (71.6%) were female and 34.7% of the students stayed at the hostel. Of the students, 44.4%, 27.5%, and 28.2% attended were the second-, third-, and fourth-year students, respectively. Participants were asked about problems related to caring for patients who speak different languages. The mean score for the Intercultural Sensitivity Scale was 89.42 ± 13.55 and the total score for all students for the Assertiveness Scale was 112.64 ± 15.61. We identified a positive relationship between total scores for the Intercultural Sensitivity Scale and the Assertiveness Scale ( p < .001). There was relationship between cultural sensitivity and gender and want to work overseas; assertiveness and year of nursing education and want to work overseas. Nursing students at both schools had a moderate level of cultural sensitivity and assertiveness. It has been determined that as assertiveness level of the students increased, intercultural sensitivity of them also increased. Consequently, it is concluded that training as assertive and self-confident individuals during the nursing education of students has a contribution to making patient-specific and culture-sensitive care.

    Isolated neurons in long-term culture provide a unique opportunity to address important problems in neuronal development. In the present study we established conditions for cryopreservation and long-term primary culture of isolated embryonic hippocampal neurons. This culture system was then used for initial characterizations of the development of neuroarchitecture and neurotransmitter response systems. Cryoprotection with 8% dimethylsulfoxide, slow freezing, and rapid thawing provided high-yield cultures which appeared normal in terms of cell types, mitotic ability, axonal and dendritic outgrowth, and sensitivity to glutamate neurotoxicity. A reduced medium volume and moderate elevation in extracellular K+ to 20 mM promoted survival of isolated neurons through 3 weeks of culture. The outgrowth of axons and dendrites in pyramidal-like neurons was found to differ over a 3-week culture period such that axons continued to grow at a relatively constant rate while dendritic outgrowth slowed during the second week and ceased by the end of week 3. Developmental changes were also observed in the sensitivity of pyramidal neurons to glutamate neurotoxicity; functional kainate/quisqualate receptors were present during the first week of culture, while responses to N-methyl-D-aspartic acid (NMDA) did not appear until the second week. The technologies for cryopreservation and long-term culture of isolated hippocampal neurons reported here provide a useful system in which to address a variety of problems in development neuroscience.

    As schools are becoming increasingly diverse in their scope and clientele, any examination of the interaction of culturally sensitive factors of students' learning environments with learning science assumes critical importance. The purpose of this exploratory study was to develop an instrument to assess learning environment factors that are culturally sensitive, to provide initial validation information on the instrument and to examine associations between students' perceptions of their learning environments and their attitudes towards science and achievement of enquiry skills. A measure of these factors of science student's learning environment, namely the Cultural Learning Environment Questionnaire (CLEQ), was developed from past learning environment instruments and influenced by Hofstede's four dimensions of culture (Power Distance, Uncertainty Avoidance, Individualism, and Masculinity/Femininity). The reliability and discriminant validity for each scale were obtained and associations between learning environment, attitude to science and enquiry skills achievement were found.

    High levels of mental disorders, especially PTSD, are commonly known among groups of people forced to leave their homeland as a consequence of war-related experiences (e. g. armed conflict, torture or persecution). Depending on the cultural background the perceptions of illnesses vary, different symptom presentation and thereupon different coping strategies respectively expectations towards health care services exist. To minimize the danger of misdiagnosis by different experts working with refugees in the host countries, a culture-sensitive diagnostic approach is needed from the beginning. This article describes important aspects of culture-sensitive diagnostics by means of 2 commented case reports. Special focus is set on the aspect of linguistic and in a broader sense cultural comprehension between therapist, client and if necessary language mediator. © Georg Thieme Verlag KG Stuttgart · New York.

    Aim This study was part of a double-blind randomised controlled trial aimed to evaluate the effects of culture-sensitive patient information materials (PIM) compared with standard translated material. The study aimed to obtain the data for the development of culture sensitive PIM about unipolar depression for the 4 largest migrant groups in Germany (Turkish, Polish, Russian and Italian migration background). Method A qualitative study using 4 manual-based focus groups (FG), one for each migrant group, with 29 participants (9 with a Turkish (TüG), 8 with a Polish (PoG), 5 with a Russian (RuG) and 7 with an Italian (ItG) migration background) was conducted. The discussions were recorded, transcribed and analyzed using qualitative content analysis. Results 7 categories were identified. For the (1.) development of a good culture-sensitive PIM an easy language, a clear structure, an assessable extent of information and the avoidance of stereotypes were highlighted cross-culturally in all four FG. RuG and PoG had the largest (2.) lack of information about the German health care system. Concerning the (3.) illness perception RuG named problems with recognizing and understanding depression. PoG, RuG and TüG thematized (4.) feared consequences of the illness and of professional helpseeking. ItG, PoG, RuG had fears concerning (5.) psychotropic drugs as a result from insufficient knowledge about medication. For (6.) doctor-patient relationship cultural specifics were identified in RuG and TüG and for (7.) migration or culture specific reasons for depression in RuG, ItG and TüG. Conclusion Although the identified categories were relevant for all or for the majority of migrant groups, for most categories specific cultural aspects were discovered. These findings show the importance of a culture sensitive adaptation of PIM. © Georg Thieme Verlag KG Stuttgart · New York.

    Study abroad (SA) experiences for health professions students may be used to heighten cultural sensitivity to future patients and incorporate interprofessional education (IPE). Two groups of nursing and pharmacy students participated in an SA elective over a 2-year period, traveling to China and India. Both groups improved significantly in knowledge, awareness, and skills following the travel experiences. Student reflections indicate that the SA experience was transformative, changing their views of travel, other cultures, personal environment, collaboration with other health professionals, and themselves. Use of SA programs is a novel method to encourage IPE, with a focus on enhancing the acquisition of cultural competency skills. Copyright 2016, SLACK Incorporated.

    Mesenchymal stem cells (MSC) possess the distinctive feature of homing in on and engrafting into the tumor stroma making their therapeutic applications in cancer treatment very promising. Research into new effectors and external stimuli, which can selectively trigger the release of cytotoxic species from MSC toward the cancer cells, significantly raises their potential. Shock waves (SW) have recently gained recognition for their ability to induce specific biological effects, such as the local generation of cytotoxic reactive oxygen species (ROS) in a non-invasive and tunable manner. We thus investigate whether MSC are able to generate ROS and, in turn, affect cancer cell growth when in co-culture with human glioblastoma (U87) or osteosarcoma (U2OS) cells and exposed to SW. MSC were found to be the cell line that was most sensitive to SW treatment as shown by SW-induced ROS production and cytotoxicity. Notably, U87 and U2OS cancer cell growth was unaffected by SW exposure. However, significant decreases in cancer cell growth, 1.8 fold for U87 and 2.3 fold for U2OS, were observed 24h after the SW treatment of MSC co-cultures with cancer cells. The ROS production induced in MSC by SW exposure was then responsible for lipid peroxidation and cell death in U87 and U2OS cells co-cultured with MSC. This experiment highlights the unique ability of MSC to generate ROS upon SW treatment and induce the cell death of co-cultured cancer cells. SW might therefore be proposed as an innovative tool for MSC-mediated cancer treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

  11. Listening to the third voices of Pangasinan students: designing and enacting culturally sensitive curriculum

    Science.gov (United States)

    Wilder, Phillip

    2015-12-01

    This response builds upon Marie Paz Morales' "Influence of culture and language sensitive physics on science attitude achievement" by exploring how an expanded understanding of the ubiquitous nature of adolescent literacy practices and identities challenge traditional notions of "in school" and "out of school" cultural spaces. Listening to the "third voices" of adolescents can promote a deeper understanding of the complex literate lives of Pangasinan students and inform both the official and the enacted culturally sensitive curriculum. To hear the literate lives of adolescents is to push back against politically dehumanizing and "de-literacizing" neo-liberal educational policies and practices which privilege a singular, whitewashed view of literacy in order to standardize curriculum and instruction, preserve power in the hands of the powerful, and exacerbate socio-economic, racial, ethnic, and linguistic divisions.

    The authors applied cognitive-behavioral therapy (CBT) for depression using the Healthy Management of Reality treatment manual. This 16-week group treatment comprised four 4-week modules: thoughts (cognitive restructuring), activities (behavioral activation), people (interpersonal skills training), and health (addresses physical health and depression). They illustrated the use of the culture-sensitive treatment manuals by way of the member characteristics and clinical process of a Spanish-language CBT group for depression. They highlighted the challenges and satisfactions of working with a Spanish-speaking population in the public sector, and focused on how culture and socioeconomic status influence patients, and how to adapt treatment to these factors. Last, they demonstrated how technological advances integrate with culture-sensitive, evidence-based treatments to better serve this population and reduce disparities.

    The aim of this study is to explore the relations of workplace culture on nursing-sensitive organizational factors. The need for standardized and valid measures for nursing-sensitive organizational outcomes has already been recognized in the literature. A cross-sectional questionnaire survey of 21 inpatient acute care units in 9 organizations at the municipal primary healthcare level was conducted. Participants included licensed practical nurses, registered nurses, and nurse managers. Workplace culture, especially the overarching factor of stress, correlated with the use of supplemental nursing staff and patients' length of stay. It is essential to find and test workplace-sensitive indicators so that managers will have a wider range of methods to plan and evaluate nursing outcomes.

    Differences in the way human and mouse fibroblasts experience senescence in culture had long puzzled researchers. While senescence of human cells is mediated by telomere shortening, Parrinello et al. demonstrated that senescence of mouse cells is caused by extreme oxygen sensitivity. It was hypothesized that the striking difference in oxygen sensitivity between mouse and human cells explains their different rates of aging. To test if this hypothesis is broadly applicable, we cultured cells from 16 rodent species with diverse lifespans in 3% and 21% oxygen and compared their growth rates. Unexpectedly, fibroblasts derived from laboratory mouse strains were the only cells demonstrating extreme sensitivity to oxygen. Cells from hamster, muskrat, woodchuck, capybara, blind mole rat, paca, squirrel, beaver, naked mole rat and wild-caught mice were mildly sensitive to oxygen, while cells from rat, gerbil, deer mouse, chipmunk, guinea pig and chinchilla showed no difference in the growth rate between 3% and 21% oxygen. We conclude that, although the growth of primary fibroblasts is generally improved by maintaining cells in 3% oxygen, the extreme oxygen sensitivity is a peculiarity of laboratory mouse strains, possibly related to their very long telomeres, and fibroblast oxygen sensitivity does not directly correlate with species' lifespan.

    Full Text Available For decades, bacteriophages (phages have been used for Brucella species identification in the diagnosis and epidemiology of brucellosis. Traditional Brucella phage typing is a multi-day procedure including the isolation of a pure culture, a step that can take up to three weeks. In this study, we focused on the use of brucellaphages for sensitive detection of the pathogen in clinical and other complex samples, and developed an indirect method of Brucella detection using real-time quantitative PCR monitoring of brucellaphage DNA amplification via replication on live Brucella cells. This assay allowed the detection of single bacteria (down to 1 colony-forming unit per milliliter within 72 h without DNA extraction and purification steps. The technique was equally efficient with Brucella abortus pure culture and with mixed cultures of B. abortus and α-proteobacterial near neighbors that can be misidentified as Brucella spp., Ochrobactrum anthropi and Afipia felis. The addition of a simple short sample preparation step enabled the indirect phage-based detection of B. abortus in spiked blood, with the same high sensitivity. This indirect phage-based detection assay enables the rapid and sensitive detection of live B. abortus in mixed cultures and in blood samples, and can potentially be applied for detection in other clinical samples and other complex sample types.

    Endothelin-1 (ET-1) is recognized as being involved in the pathophysiology of cerebrovascular diseases. Using organ culture as a model for possible pathological changes we studied changes in ET(A) and ETB receptor function using a sensitive in vitro method. We observed an up-regulation of the ET......(B) receptor and an amazingly increased sensitivity to ET-1 by 3 log units in pEC50; pEC50(fresh) was 8.7 +/- 0.1, and pEC50(cultured) was 11.7 +/- 0.3. pA2 for FR139317 in the fresh vessel was 7.0 +/- 0.2 whereas it could not be obtained for the cultured vessel, indicating a possible cross-talk between the ET......(A) and ET(B) receptors. The increased sensitivity to ET-1 could also take place during cerebrovascular disease such as stroke or haemorrhage rendering the vessels considerably more sensitive to ET-1....

    In this study, the determination of Helicobacter pylori (H. pylori) by culture, histopathological and serological methods in cases of endoscopically diagnosed as duodenitis and duodenal ulcer (DU), a comparison of their relative advantages, and its antibiotic sensitivities were investigated. Helicobacter pylori was investigated using 3 methods (culture, histopathological and serological examination) in 50 patients (25 diagnosed with duodenitis and 25 with DU) at the Department of Gastroenterohepatology, Istanbul Haydarpasa Numune Hospital, Turkey between December 2000 and February 2001. An investigation into its antibiotic sensitivities to amoxicillin, clarithromycin, metronidazole and azithromycin by disc diffusion methods and to amoxicillin and clarithromycin by E-test were investigated. Helicobacter pylori bacteria were observed in Gram stained preparates prepared from biopsy material in 34 out of 50 patients (68%), and were able to be produced in active culture in all these cases. Histopathological examination revealed the presence of H. pylori in 80% cases of DU and 60% cases of duodenitis; anti-CagA(IgG) was positively determined in 88% DU cases and in 60% duodenitis cases. There was a significant difference between the 2 groups in terms of diagnosis by histopathological and serological methods. The difference between the 2 groups produced in active culture in 84% cases of DU cases and 52% of duodenitis was statistically significant (p=0.0322). Using the E-test and disc diffusion methods, 8.8% of the strains that reproduced in culture were resistant to and 91.2% were sensitive to clarithromycin. All strains were determined to be sensitive to amoxicillin: 17.6% of the strains were determined to be resistant to metronidazole, 11.7% to azithromycin. It was observed that Gram staining is a rapid and reliable method of pre-diagnosis for H. pylori; that histopathological examination methods are of considerable importance in diagnosis; and that the investigation of

    A bioimpedance platform is presented as a promising tool for non-invasive real-time monitoring of the entire process of three-dimensional (3D) cell culturing in a hydrogel scaffold. In this study, the dynamics involved in the whole process of 3D cell culturing, starting from polymerisation of a bare 3D gelatin scaffold, to human mesenchymal stem cell (MSC) encapsulation and proliferation, was monitored over time. The platform consists of a large rectangular culture chamber with four embedded vertical gold plate electrodes that were exploited in two- and three terminal (2T and 3T) measurement configurations. By switching between the different combinations of electrode couples, it was possible to generate a multiplexing-like approach, which allowed for collecting spatially distributed information within the 3D space. Computational finite element (FE) analysis and electrochemical impedance spectroscopic (EIS) characterisation were used to determine the configurations' sensitivity field localisation. The 2T setup gives insight into the interfacial phenomena at both electrode surfaces and covers the central part of the 3D cell culture volume, while the four 3T modes provide focus on the dynamics at the corners of the 3D culture chamber. By combining a number of electrode configurations, complementary spatially distributed information on a large 3D cell culture can be obtained with maximised sensitivity in the entire 3D space. The experimental results show that cell proliferation can be monitored within the tested biomimetic environment, paving the way to further developments in bioimpedance tracking of 3D cell cultures and tissue engineering.

    Full Text Available BACKGROUND Urinary tract infection is very common all over the world and in India more than 10 million cases are reported per year. It is one of the common infections diagnosed in the outpatients as well as the hospitalised patients. Empirical treatment of community acquired urinary tract infections are determined by the antibiotic sensitivity in a population. This study was conducted to determine the antimicrobial sensitivity amongst the uropathogens to help establish local guidelines on treatment of urinary tract infection. MATERIALS AND METHODS In this study, we collected 1306 samples from patients in whom we suspected to have urinary tract infection based on clinical signs and symptoms (e.g. with fever (greater than 38°C without another explanation or from a patient who had at least one urinary symptom (dysuria, urgency, frequency, or suprapubic pain or tenderness in our hospital during January 2016-June 2016. RESULTS Urine cultures were positive for 18% of the patients. Among these cultures, Klebsiella pneumonia (41%, Escherichia coli (35% and Pseudomonas aeruginosa (7% were the common organisms found. Highest antimicrobial sensitivity amongst these pathogens was found with cefoperazone/sulbactam and amikacin. CONCLUSION Cefoperazone/sulbactam and amikacin were the highly sensitive systemic antibiotics while ciprofloxacin and norfloxacin were the sensitive oral antibiotics in our locality.

    Full Text Available Background: Rapid diagnosis is essential to decrease the morbidity and mortality of Pott′s disease. The bacteriological methods are time-consuming or insensitive. Polymerase chain reaction (PCR provides a rapid diagnostic tool and hope for early diagnosis of this disease. The aim of this study was to compare and assess of a rapid and effective method among diagnostic battery (Ziehl-Neelsen (ZN microscopy, BACTEC culture and PCR of Pott′s disease. Materials and Methods: Sixty-five specimens from clinico-radiological suspected cases of Pott′s disease were included in this study. They were processed for ZN microscopy, BACTEC culture, and PCR IS6110. The tests tool′s efficiency, positive agreement Kc (Kappa coefficient, and significance level (P value were calculated for correlation between PCR and performed tests. Results: The PCR sensitivity reached to 96% and 46.3% among positive and negative specimens on ZN microscopy. Further, 94% and 36.4% sensitivity were found among positive and negative specimens by BACTEC culture. The total 38 (58.5% specimens were detected either ZN microscopy or by BACTEC culture. Thus, the overall sensitivity and specificity of PCR were 95% and 74.1%. The kappa coefficient and P value, calculated for PCR against BACTEC culture and combined results of performed bacteriological tests were (Kc=0.60, (P<0.001 and (Kc=0.70, (P<0.001, respectively. Above statistical relations showed a fair agreement with significant differences. Conclusion: The PCR IS6110 may be useful in rapid detection of clinico-radiological suspected cases of Pott′s disease and those that are negative with bacteriological methods.

    The article presents analysis of sensitivity to antibacterial preparations of typical and biofilm culture of museum strain of Corynebacterium diphtheriae gravis tox+ SV-665. The strain was obtained from the L.A. Tarasevitch state research institute of standardization and control of medical biological preparations. The second strain C. diphtheriaecirculates gravis tox+ circulates in population of the Rostov oblast and it was recovered from patient with diagnosis of "localized form of diphtheria" by bacteriologic laboratory "1002 CGSEN SKVO" of Rostov-on-Don. The week and month biofilm cultures of both strains of C. diphtheriae gravis tox+ were used. The sensitivity to antibacterial preparations of typical and biofilm cultures of museum and circulating in population strains of agent of diphtheria were detected using minimal suppressing concentration by technique of serial dilutions in fluid growth medium. It is demonstrated that the most effective in respect of C. diphtheriae are such preparations as cefotaxinum, gentamycinum, lincomycin, canamycin and cefasolin. The sensitivity of pathogen in composition of biofilm to these preparations has no changes.

    This review introduces the concept of culture-sensitive health communication. The basic premise is that congruency between the recipient's cultural characteristics and the respective message will increase the communication's effectiveness. Culture-sensitive health communication is therefore defined as the deliberate and evidence-informed adaptation of health communication to the recipients' cultural background in order to increase knowledge and improve preparation for medical decision making and to enhance the persuasiveness of messages in health promotion. To achieve effective health communication in varying cultural contexts, an empirically and theoretically based understanding of culture will be indispensable. We therefore define culture, discuss which evolutionary and structural factors contribute to the development of cultural diversity, and examine how differences are conceptualized as scientific constructs in current models of cultural differences. In addition, we will explicate the implications of cultural differences for psychological theorizing, because common constructs of health behavior theories and decision making, such as attitudes or risk perception, are subject to cultural variation. In terms of communication, we will review both communication strategies and channels that are used to disseminate health messages, and we will discuss the implications of cultural differences for their effectiveness. Finally, we propose an agenda both for science and for practice to advance and apply the evidence base for culture-sensitive health communication. This calls for more interdisciplinary research between science and practice but also between scientific disciplines and between basic and applied research. © The Author(s) 2015.

    This study focused on a possible temperament-by-culture interaction. Specifically, it explored whether a basic temperament/personality trait (sensory processing sensitivity; SPS), perhaps having a genetic component, might moderate a previously established cultural difference in neural responses when making context-dependent vs context-independent judgments of simple visual stimuli. SPS has been hypothesized to underlie what has been called inhibitedness or reactivity in infants, introversion in adults, and reactivity or responsivness in diverse animal species. Some biologists view the trait as one of two innate strategies-observing carefully before acting vs being first to act. Thus the central characteristic of SPS is hypothesized to be a deep processing of information. Here, 10 European-Americans and 10 East Asians underwent functional magnetic resonance imaging while performing simple visuospatial tasks emphasizing judgments that were either context independent (typically easier for Americans) or context dependent (typically easier for Asians). As reported elsewhere, each group exhibited greater activation for the culturally non-preferred task in frontal and parietal regions associated with greater effort in attention and working memory. However, further analyses, reported here for the first time, provided preliminary support for moderation by SPS. Consistent with the careful-processing theory, high-SPS individuals showed little cultural difference; low-SPS, strong culture differences.

    Full Text Available Background: Patient-centered culturally sensitive health care (PC-CSHC is a best practice approach for improving health-care delivery to culturally diverse populations and reducing health disparities. Despite patients’ report that cultural sensitivity by health-care office staff is an important aspect of PC-CSHC, the majority of available research on PC-CSHC focuses exclusively on health-care providers. This may be due in part to the paucity of instruments available to assess the cultural sensitivity of health-care office staff. The objective of the present study is to determine the psychometric properties of the Tucker-Culturally Sensitive Health Care Office Staff Inventory-Self-Assessment Form (T-CSHCOSI-SAF. This instrument is designed to enable health-care office staff to self-assess their level of agreement that they display behaviors and attitudes that culturally diverse patients have identified as office staff cultural sensitivity indicators. Methods: A sample of 510 health-care office staff were recruited at 67 health-care sites across the United States. These health-care office staff anonymously completed the T-CSHCOSI-SAF and a demographic data questionnaire. Results and Level of Evidence: Confirmatory factor analyses of the T-CSHCOSI-SAF revealed that this inventory has 2 factors with high internal consistency reliability (Cronbach’s αs= .916 and .912. Conclusion and Implications: The T-CSHCOSI-SAF is a useful inventory for health-care office staff to assess their own level of patient-centered cultural sensitivity. Such self-assessment data can be used in the development and implementation of trainings to promote patient-centered cultural sensitivity of health-care office staff and to help draw the attention of these staff to displaying patient-centered cultural sensitivity.

    Physicians and medical institutions in the United States are placing increasing emphasis on providing culturally sensitive care for patients, such as implementing a Confucian family-based model of medical decision making when caring for elderly Chinese patients. In this article, I articulate various reasons why deferring to the family is not a guarantee of culturally sensitive care, particularly when family members are first-generation Chinese-Americans. Nonetheless, I offer several suggestions to help physicians, medical institutions, and family members to provide more culturally sensitive care for elderly Chinese patients.

    To explore the influence of workplace culture on sickness absences, overtime work and occupational injuries in municipal primary health care. The need to improve nursing sensitive outcomes has been highlighted. Therefore, an adequate understanding of the influence of workplace culture on nursing-sensitive nurse outcomes is essential for nurse managers to meet the requirements of improving nursing outcomes. A cross-sectional survey design was used to incorporating the data from 21 inpatient acute care units of nine organisations at the Finnish municipal primary health care system from 2011 to 2012. Findings emphasise in particular the importance of the practice environment as being an interpretative factor for nurses' absences owing to sickness, overtime work and occupational injuries. To ensure favourable nursing sensitive outcomes it is essential that there is a shared interest in the unit to invest in the creation of a supportive practice environment. Outcome improvements require a special focus on issues related to nursing management, adequate staffing and resources and intention to leave. © 2014 John Wiley & Sons Ltd.

    The objective of the study was to develop a culturally sensitive psychiatric screening instrument valid for Ethiopians in Ethiopia and Israel. The study sample was composed of 356 Amharic-speaking Ethiopians from Ethiopia and Israel, aged 18-55, divided into three groups: i) general population; ii) people in non-psychiatric treatment; iii) people in psychiatric treatment. They were interviewed with the Self-Reporting Questionnaire (SRQ), modified to include 10 culturally specific items, and the Brief Psychiatric Research Scale (BPRS) as a criterion of psychopathology. Physicians also completed an encounter form about the presence of mental health symptoms in participants. To make the questions more culturespecific, the translation of 12 items on the SRQ was changed. The content, construct, and criterion validity of each question were also examined, leading to the deletion of five items. The validity of the revised instrument (SRQ-F) was superior to that of the original instrument (SRQ). This study demonstrates the need for psychiatric screening instruments to be adapted to different cultures by incorporating meaningful translations and adding culturally specific items.

    Mineral composition is controlled by a host of environmental factors during precipitation. To build accurate paleo-reconstructions we need to separate the impact of each parameter on proxy behavior and use these data to build a chemical-scale understanding of mineral growth. Biomineral culture and inorganic precipitation experiments, where growth parameters can be manipulated independently, are uniquely suited to calibrate proxies and probe mechanism. Culture and precipitation experiments often involve overgrowth of an initial material. For example, seed crystals are used to control mineralogy and avoid nucleation during inorganic precipitation, while culture experiments in marine organisms typically start with wild specimens. New growth corresponding to the experimental conditions must be resolved from the initial material. Separation is typically achieved using microanalysis, skeletal dissection, or estimates of the initial mass and composition. Each approach imposes limits on the accuracy, precision or types of materials that can be analyzed. Slow growth rates and complicated geometries can make these techniques especially challenging when applied to biominerals. We present a method of compositional analysis for use in biological culture and inorganic growth experiments that overcomes many of these challenges. This method relies on growth in a mixed element stable isotope spike, requires neither the initial mass nor the initial composition to be known, harnesses the precision and sensitivity of bulk analysis, and applies even when it is impossible to physically identify newly grown material. Error analysis suggests this method can significantly improve the precision of metal/calcium measurements in experimentally grown material compared to current methods. Furthermore, the method can isolate different events through time, separating, for example, the impact of day and night cycles on biomineral composition. We will present metal/calcium ratios measured using the

    In vitro grown shoots cultures (Prunus salicina × Prunus persica), elicited by methyl jasmonate (MJ), are reported here for the first time to prepare a natural dye for dye-sensitized solar cells (DSSC). Redox properties of the dye, its photostability, and light absorption properties suggested it as a candidate as natural photosensitizers for TiO2 photoelectrodes. Redox properties of the dye influence the DSSC production of photocurrent, thus three antioxidant assays were performed in order to characterize the antioxidant potential of this dye. The dye exhibited a high antioxidant activity in all the assays performed. Photostability assay revealed that the dye was quite stable to light. The power conversion efficiency that we obtained (0.53%) was comparable to the data by other authors with anthocyanins-based dyes from in vivo grown plants. Finally, we compared the dye with the partially purified one as photosensitizer in DSSC. The results indicated that the raw pigment from in vitro shoot cultures of P. salicina × P. persica elicited with MJ can be proposed without the needing of any other chemicals, thermal or purification process, or pH adjustments, as a dye for natural sensitized solar cells.

    Cross-cultural differences in Easterners and Westerners have been observed in different cognitive domains. Differential sensitivity to the relationship between objects and contexts might be an underlying cognitive mechanism for these differences. Twenty-one Chinese and 22 Germans participated in a three-stimulus event-related potential oddball task. They were instructed to monitor geometrical forms filled in black (targets) that were presented among a series of blank geometrical forms (standards). Novel stimuli were colored images of common objects. Robust novelty P3 and target P3 over the entire scalp were observed in both groups. As compared with the German group, Chinese participants showed larger amplitudes of novelty P3 and target P3 over frontal regions and earlier peak latency for target P3. This indicates a higher sensitivity to the relationship between contexts and objects in the Chinese as compared with the German group, which might be an underlying mechanism for cross-cultural differences reported in many cognitive domains.

  14. How commercial and ``violent'' video games can promote culturally sensitive science learning: some questions and challenges

    In their paper, Muñoz and El-Hani propose to bring video games into science classrooms to promote culturally sensitive ethics and citizenship education. Instead of bringing "educational" games, Muñoz and El-Hani take a more creative route and include games such as Fallout 3® precisely because they are popular and they reproduce ideological and violent representations of gender, race, class, nationality, science and technology. However, there are many questions that arise in bringing these commercial video games into science classrooms, including the questions of how students' capacities for critical reflection can be facilitated, whether traditional science teachers can take on the role of using such games in their classrooms, and which video games would be most appropriate to use. In this response, I raise these questions and consider some of the challenges in order to further the possibility of implementing Muñoz and El-Hani's creative proposal for generating culturally sensitive science classrooms.

  15. A rapid and sensitive method for measuring N-acetylglucosaminidase activity in cultured cells.

    Directory of Open Access Journals (Sweden)

    Victor Mauri

    Full Text Available A rapid and sensitive method to quantitatively assess N-acetylglucosaminidase (NAG activity in cultured cells is highly desirable for both basic research and clinical studies. NAG activity is deficient in cells from patients with Mucopolysaccharidosis type IIIB (MPS IIIB due to mutations in NAGLU, the gene that encodes NAG. Currently available techniques for measuring NAG activity in patient-derived cell lines include chromogenic and fluorogenic assays and provide a biochemical method for the diagnosis of MPS IIIB. However, standard protocols require large amounts of cells, cell disruption by sonication or freeze-thawing, and normalization to the cellular protein content, resulting in an error-prone procedure that is material- and time-consuming and that produces highly variable results. Here we report a new procedure for measuring NAG activity in cultured cells. This procedure is based on the use of the fluorogenic NAG substrate, 4-Methylumbelliferyl-2-acetamido-2-deoxy-alpha-D-glucopyranoside (MUG, in a one-step cell assay that does not require cell disruption or post-assay normalization and that employs a low number of cells in 96-well plate format. We show that the NAG one-step cell assay greatly discriminates between wild-type and MPS IIIB patient-derived fibroblasts, thus providing a rapid method for the detection of deficiencies in NAG activity. We also show that the assay is sensitive to changes in NAG activity due to increases in NAGLU expression achieved by either overexpressing the transcription factor EB (TFEB, a master regulator of lysosomal function, or by inducing TFEB activation chemically. Because of its small format, rapidity, sensitivity and reproducibility, the NAG one-step cell assay is suitable for multiple procedures, including the high-throughput screening of chemical libraries to identify modulators of NAG expression, folding and activity, and the investigation of candidate molecules and constructs for applications in

    Cultural diversity is becoming increasingly more important in the workplace. This is particularly true in health care organizations facing demographic shifts in the patients served and their families. This study serves to aid the development of intercultural communication training programs for health care providers by examining how cultural sensitivity and effective intercultural communication, besides helping patients, personally benefit health care providers by reducing their stress. Effective intercultural communication and cultural sensitivity were found to be related. Health care providers' levels of intercultural anxiety also were found to correlate with effective intercultural communication.

  17. Is there a genetic contribution to cultural differences? Collectivism, individualism and genetic markers of social sensitivity.

    Way, Baldwin M; Lieberman, Matthew D

    2010-06-01

    Genes and culture are often thought of as opposite ends of the nature-nurture spectrum, but here we examine possible interactions. Genetic association studies suggest that variation within the genes of central neurotransmitter systems, particularly the serotonin (5-HTTLPR, MAOA-uVNTR) and opioid (OPRM1 A118G), are associated with individual differences in social sensitivity, which reflects the degree of emotional responsivity to social events and experiences. Here, we review recent work that has demonstrated a robust cross-national correlation between the relative frequency of variants in these genes and the relative degree of individualism-collectivism in each population, suggesting that collectivism may have developed and persisted in populations with a high proportion of putative social sensitivity alleles because it was more compatible with such groups. Consistent with this notion, there was a correlation between the relative proportion of these alleles and lifetime prevalence of major depression across nations. The relationship between allele frequency and depression was partially mediated by individualism-collectivism, suggesting that reduced levels of depression in populations with a high proportion of social sensitivity alleles is due to greater collectivism. These results indicate that genetic variation may interact with ecological and social factors to influence psychocultural differences.

    In vitro testing methods for classifying sensitizers could be valuable alternatives to in vivo sensitization testing using animal models, such as the murine local lymph node assay (LLNA) and the guinea pig maximization test (GMT), but there remains a need for in vitro methods that are more accurate and simpler to distinguish skin sensitizers from non-sensitizers. Thus, the aim of our study was to establish an in vitro assay as a screening tool for detecting skin sensitizers using the human keratinocyte cell line, HaCaT. HaCaT cells were exposed to 16 relevant skin sensitizers and 6 skin non-sensitizers. The highest dose used was the dose causing 75% cell viability (CV75) that we determined by an MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay. The levels of extracellular production of interleukin-1α (IL-1α) and IL-6 were measured. The sensitivity of IL-1α was 63%, specificity was 83% and accuracy was 68%. In the case of IL-6, sensitivity: 69%, specificity: 83% and accuracy: 73%. Thus, this study suggests that measuring extracellular production of pro-inflammatory cytokines IL-1α and IL-6 by human HaCaT cells may potentially classify skin sensitizers from non-sensitizers.

    Objective To investigate the sensitivity of the human sperm motility assay for detecting endotoxin in culture medium Materials & Methods Motile sperm were separated and exposed to different concentrations of endotoxin (0.5 ng/mL, 1 ng/mL, 10 ng/mL, 1 000 ng/mL, 10 000 ng/mL, and 50 000 ng/mL), and sperm motility was determined after incubation. Effects of endotoxin on sperm motility in media without albumin were also examined. In addition, at the same concentrations of endotoxin (0.5 ng/mL, 1 ng/mL, and 10 ng/mL), the sensitivity of the human sperm motility assay was compared to those of 1-cell and 2-cell mouse embryo bioassays.Results At levels of 0.5 ng/mL~1 000 ng/mL endotoxin in media with 2 mg/mL albumin, sperm did not show significant change in motility during 24 h of incubation when compared with the control (P>0.05). However, the sperm motility was significantly inhibited at endotoxin dosages of 10 000 and 50 000 ng/mL. In the absence of albumin supplementation, at endotoxin levels of 50 000 ng/mL, and 1 000 ng/mL, there was a marked decrease in sperm motility compared with the control after 2 h or 8 h of incubation, respectively (P<0.01). In media containing 0.5 ng/mL and 1 ng/mL endotoxin, 1-cell and 2-cell mouse embryos had significantly reduced developmental rates in all developmental stages, and at the level of 10 ng/mL, the development of the embryos was arrested.Conclusion The human sperm motility assay could detect high levels of endotoxin in culture medium but its sensitivity to endotoxin would be inferior to that of the 1-cell or 2-cell mouse embryo bioassay. In the absence of albumin supplementation, the sensitivity of the sperm motility assay could be improved.

    Aim To develop a sensitive competitive ELISA for the determination of biotin in transformed yeast culture media.Methods The ELISA plate was firstly coated with Mycoplasma hyopneumoniae, and then successively incubated with rabbit ami-Mycoplasma hyopneumoniae serum and goat anti-rabbit IgG-biotin to form the solid biotin, which competed with the biotin in the solution (standard or sample) for the limited streptavidin-horse radish peroxidase conjugate. The standard calibration curve for biotin analysis was constructed in the range of 50-2000ng·L-1. Results The detection limit for biotin was found to be 83 ng·L-1 , which waa about 1000 times lower than the lowest determination concenlration in the reported ELISA for biotin analysis. The relative standard deviations for the spiked samples at biotin concerarations of 200 ng·L-1, 500 ng·L-1 , and 1000 ng·L-1 were 24.87%, 6.15%, and 7.86%, respectively, with the average recovery of 101.13%. The wild yeast and its sixty-three transformed yeast culture media were applied to the developed ELISA for the determination of biotin. It was found that the biotin concentrations in more than 85 % of the tested samples were enhanced with different increase factors after transformation. Conclusion Utilization of Mycoplasma hyopnetunoniae as the coating protein improves the precision and accmacy oftbe ELISA assay, which might be used for the biotin assay in other media.

    Full Text Available The study combined qualitative approaches with quantitative research design to come up with a survey instrument called Culture-Sensitive Physics Learning Environment Survey (CS-PLES.This survey instrument is intended to extract the learners’ beliefs and expectations on the integration of culture and language in the teaching and learning process of physics concepts. Significant contribution of the instrument can be traced to establishing and defining the constructs and categories on how curriculum localization and context-based science learning can be developed aligned with students’ expectations and beliefs. The development process employed non-conventional processes adopted from literature which included pilot study to identify pre-deterministic constructs and specific categories for the items to be included in the survey. Data analysis included descriptive statistics and factor analysis to establish the categories or constructs of the survey instruments. Reliability measures of the instrument and its respective constructs were established for standardization. These categories were intended to aid researchers for an in-depth analysis when the instrument is administered for its purpose. The raw statistical categories were qualitatively paralleled with the pre-deterministic constructs to establish congruence of the survey tool to Instructional Congruence Framework (ICF.

  2. NRSF causes cAMP-sensitive suppression of sodium current in cultured hippocampal neurons

    2002-01-01

    The neuron restrictive silencer factor (NRSF/REST) has been shown to bind to the promoters of many neuron-specific genes and is able to suppress transcription of Na(+) channels in PC12 cells, although its functional effect in terminally differentiated neurons is unknown. We constructed lentiviral vectors to express NRSF as a bicistronic message with green fluorescent protein (GFP) and followed infected hippocampal neurons in culture over a period of 1-2 wk. NRSF-expressing neurons showed a time-dependent suppression of Na(+) channel function as measured by whole cell electrophysiology. Suppression was reversed or prevented by the addition of membrane-permeable cAMP analogues and enhanced by cAMP antagonists but not affected by increasing protein expression with a viral enhancer. Secondary effects, including altered sensitivity to glutamate and GABA and reduced outward K(+) currents, were duplicated by culturing GFP-infected control neurons in TTX. The striking similarity of the phenotypes makes NRSF potentially useful as a genetic "silencer" and also suggests avenues of further exploration that may elucidate the transcription factor's in vivo role in neuronal plasticity.

    In Canada, the care provided by families occurs in an increasingly multiethnic context. Against this backdrop, the present qualitative study aims to explore the needs/expectations and solutions not only of (female) natural caregivers of an elderly relative hailing from Haiti (presented in terms of tracking cases) but also of remunerated home care providers - all with a view to developing a culturally sensitive service offering. As such, this study works from a conceptual framework centring on the negotiation of a common area of agreement between the stakeholders involved (i.e., natural caregivers and home care providers). To this end, focus groups and individual interviews were conducted among 15 caregivers and 37 home care providers. The three recurrent themes emerging from the data analysis concern, in context, the needs/expectations and solutions surrounding the experience of service use, barriers to use, and the relationships between natural caregivers and home care providers. The statements of both groups evidenced a consistency of views and have thus provided a basis for developing some recommendations acceptable to all stakeholders from the perspective of making culturally-based adjustments to the service offering.

    To investigate the spectrum of organisms causing endophthalmitis and their sensitivity to commonly used antimicrobial agents. Medical records of 80 consecutive patients treated at Beyoglu Eye Hospital for endophthalmitis from January 2001 to April 2006 were reviewed. Specimens were obtained from either the vitreous (93%, 81/87) or anterior chamber (7%, 6/87) during pars plana vitrectomy or vitreous tap, and were inoculated into blood culture bottles. A Kirby-Bauer disk diffusion test was performed to determine antibiotic susceptibility. The outcome measures included isolates identified and antibiotic sensitivity of the specimens. Fifty-six of 87 (64.4%) isolates were Gram-positive organisms, 29 (33.3%) were Gram-negative organisms, and 2 (2.3%) were fungi. The most common organism group identified was coagulase-negative staphylococci in 26.4% (23/87). While vancomycin was active against all Gram-positive isolates tested (100%), ceftazidime had the highest susceptibility rate (100%) for Gram-negative organisms isolated. Although coagulase-negative micrococci predominated in this series, a high isolation rate for Gram-negative organisms was obtained. High susceptibility rates for ofloxacin make it an alternative to ceftazidime and vancomycin in both Gram-negative- and Gram-positive-derived endophthalmitis, respectively. Studies with larger series and additional antibiotics are needed to confirm these findings. (c) 2008 S. Karger AG, Basel

    Mycobacterium avium ssp. paratuberculosis (MAP) can be shed in feces, milk, and colostrum. The goal of this study was to assess assays that detect MAP in these sample types, including effects of lactation stage or season. Understanding the performance of these assays could improve how they are used, limiting the risk of infection to calves. Forty-six previously confirmed MAP-positive cows from 7 Atlantic Canadian dairy farms were identified for colostrum sampling and monthly sampling of milk and feces over a 12-mo period. Samples were assayed for MAP using solid culture, broth culture, and direct real-time PCR (qPCR). Across assay types, test sensitivity when applied to milk samples averaged 25% of that when applied to fecal samples. For colostrum samples, sensitivity depended on assay type, with sensitivity of qPCR being approximately 46% of that in feces. Across sample types, sensitivity of qPCR was higher than that of the other assays. Sensitivity of qPCR, when applied to milk samples, was significantly higher in summer than in other seasons. Summer was also the season with highest agreement between milk and fecal samples collected within the same month. Our results suggest that qPCR would detect more cows shedding MAP in their milk and colostrum than solid or broth culture assays, particularly during the summer, thus providing better management information to limit exposure of calves to this infectious organism.

    Full Text Available Abstract Background Salmonella Typhi causes an estimated 21 million new cases of typhoid fever and 216,000 deaths every year. Blood culture is currently the gold standard for diagnosis of typhoid fever, but it is time-consuming and takes several days for isolation and identification of causative organisms. It is then too late to initiate proper antibiotic therapy. Serological tests have very low sensitivity and specificity, and no practical value in endemic areas. As early diagnosis of the disease and prompt treatment are essential for optimal management, especially in children, a rapid sensitive detection method for typhoid fever is urgently needed. Although PCR is sensitive and rapid, initial research indicated similar sensitivity to blood culture and lower specificity. We developed a fast and highly sensitive blood culture PCR method for detection of Salmonella Typhi, allowing same-day initiation of treatment after accurate diagnosis of typhoid. Methods An ox bile tryptone soy broth was optimized for blood culture, which allows the complete lysis of blood cells to release intracellular bacteria without inhibiting the growth of Salmonella Typhi. Using the optimised broth Salmonella Typhi bacteria in artificial blood samples were enriched in blood culture and then detected by a PCR targeting the fliC-d gene of Salmonella Typhi. Results Tests demonstrated that 2.4% ox bile in blood culture not only lyzes blood cells completely within 1.5 hours so that the intracellular bacteria could be released, but also has no inhibiting effect on the growth of Salmonella Typhi. Three hour enrichment of Salmonella Typhi in tryptone soya broth containing 2.4% ox bile could increase the bacterial number from 0.75 CFU per millilitre of blood which is similar to clinical typhoid samples to the level which regular PCR can detect. The whole blood culture PCR assay takes less than 8 hours to complete rather than several days for conventional blood culture

    NanoSIMS was used to identify and com¬positionally characterize the micron scale region of skeletal growth resulting from a short coral culture experiment. Using this technique we quantify the sensitivity of Sr/Ca, a proxy for temperature, to aragonite saturation (Ω), a parameter that varied in the past ocean and is predicted to change with continued ocean acidification. Five adult branches of the surface coral Stylophora sp. were all grown at 25 °C but at different and near constant carbonate ion concentrations, from 180 to 400 µM (pH of 7.9 to 8.5), yielding a two-fold range in calcification rate. Despite the range of Ωs and calcification rates, the average Sr/Ca of nanoSIMS spot measurements corresponding to each condition are within 1.2% (2σ std. dev. of the 5 means). Furthermore, the average Sr/Ca measured in this study agrees with two previous coral culture experiments conducted at the same temperature but where Ω was not controlled. These results suggest carbonate ion concentration is not a complicating factor to Sr/Ca paleothermometry over this range of Ω. Within the framework of a closed system (Rayleigh) model for biomineralization, similar Sr/Ca ratios suggest similar amounts of Rayleigh fractionation. Combined with existing data for low Ω conditions, the extent of Rayleigh fractionation is used to test alternative biomineralization models governing the acid-base chemistry of the calcifying fluid. Assuming that coral use alkalinity pumping to increase local calcifying fluid carbonate ion concentration, we try to understand what controls this pumping. Under most conditions, Sr/Ca ratios are consistent with a scenario where calcifying fluid alkalinity increases until reaching a target pH. However, under conditions of very low seawater Ω, coral cannot pump enough alkalinity to reach the target pH. Below this threshold value, between approximately 1<Ω<2.4, coral pump a maximal and finite amount of alkalinity. The interaction between these rules

    Cultural competency is an integral component in undergraduate nursing education to provide patient-centered care and addressing patients' cultural differences. Students need to consider the prevalence of alcohol and other drug use/misuse in patients from all cultures. This project combines cultural competency education, simulation, and educating students to use screening, brief intervention, and referral to treatment for alcohol and other drug use. Culturally diverse simulation scenarios were developed and used in the simulation lab with students to reduce stigma surrounding other cultures while learning an evidence-based practice to screen and intervene with patients who use/misuse substances. Results show students value simulation and 91% of the students felt that they were able to apply culturally competent knowledge after the simulation experience. Cultural competency principles can be embedded in teaching the broader evidence-based practice of screening, brief intervention, and referral to treatment with undergraduate students. This is a replicable teaching methodology that could be adapted in other schools of nursing.

  11. Different sensitivities of cultured mammalian cells towards aphidicolin-enhanced DNA effects in the comet assay.

    Speit, Günter; Schütz, Petra; Bausinger, Julia

    2016-06-01

    The comet assay in combination with the polymerase inhibitor aphidicolin (APC) has been used to measure DNA excision repair activity, DNA repair kinetics and individual DNA repair capacity. Since APC can enhance genotoxic effects of mutagens measured by the comet assay, this approach has been proposed for increasing the sensitivity of the comet assay in human biomonitoring. The APC-modified comet assay has mainly been performed with human blood and it was shown that it not only enhances the detection of DNA damage repaired by nucleotide excision repair (NER) but also damage typically repaired by base excision repair (BER). Recently, we reported that in contrast to blood leukocytes, A549 cells (a human lung adenocarcinoma cell line) seem to be insensitive towards the repair-inhibiting action of APC. To further elucidate the general usefulness of the APC-modified comet assay for studying repair in cultured mammalian cells, we comparatively investigated further cell lines (HeLa, TK6, V79). DNA damage was induced by BPDE (benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide) and MMS (methyl methanesulfonate) in the absence and presence of APC (3 or 15μM). APC was either added for 2h together with the mutagen or cells were pre-incubated for 30min with APC before the mutagen was added. The results indicate that the cell lines tested differ fundamentally with regard to their sensitivity and specificity towards the repair-inhibiting effect of APC. The actual cause for these differences is still unclear but potential molecular explanations are discussed. Irrespective of the underlying mechanism(s), our study revealed practical limitations of the use of the APC-modified comet assay.

    2014-06-01

    Appearance-based rejection sensitivity (appearance-RS) is the tendency to anxiously expect, readily perceive, and overreact to signs of rejection based on one's appearance, and is associated with a number of psychological and social problems (Park, 2007). This study of 380 adolescents (Mage = 13.84) examined a model linking the appearance culture between friends with appearance-RS in adolescent boys and girls, via internalisation of appearance ideals, social comparison, and body dissatisfaction. Gender differences were also tested. Consistent with expectations, appearance-focused characteristics of the friendship context were associated with heightened appearance-RS via internalization of appearance ideals, social comparison, and body dissatisfaction. The appearance-focused friend characteristics that were associated with appearance-RS included exposure to friends' appearance conversations, appearance teasing that caused distress, and perceived pressure to be attractive. Notably, associations rarely differed for boys and girls, with one exception: the association between BMI and body dissatisfaction was stronger in girls than in boys.

  13. Stability and Sensitivity Analysis of a Plant Disease Model with Continuous Cultural Control Strategy

    2014-01-01

    Full Text Available In this paper, a plant disease model with continuous cultural control strategy and time delay is formulated. Then, how the time delay affects the overall disease progression and, mathematically, how the delay affects the dynamics of the model are investigated. By analyzing the transendental characteristic equation, stability conditions related to the time delay are derived for the disease-free equilibrium. Specially, when R0=1, the Jacobi matrix of the model at the disease-free equilibrium always has a simple zero eigenvalue for all τ≥0. The center manifold reduction and the normal form theory are used to discuss the stability and the steady-state bifurcations of the model near the nonhyperbolic disease-free equilibrium. Then, the sensitivity analysis of the threshold parameter R0 and the positive equilibrium E* is carried out in order to determine the relative importance of different factors responsible for disease transmission. Finally, numerical simulations are employed to support the qualitative results.

  14. Simple and sensitive method for monitoring drug-induced cell injury in cultured cells

    1985-06-01

    A simple, sensitive method has been developed for evaluating cell injury noninvasively in monolayer cells in culture. The cell ATP pool was radiolabeled by incubating the cells with (/sup 14/C)adenine. The uptake and incorporation of (/sup 14/C)adenine was shown to proportional to the number of cells. As determined by HPLC, about 65-70% of the incorporated /sup 14/C label was in the ATP pool, 15-20% was in the ADP pool, and the rest was in the 5'-AMP pool. When prelabeled cells were exposed to toxic drugs (acetaminophen, calcium ionophore A-23187, or daunomycin) there was a marked decrease in cell ATP with a concomitant increase in leakage of labeled nucleotides, mainly 5'-AMP and 5'IMP. The authors have shown that leakage of /sup 14/C label into the medium from the prelabeled cells may be employed for quantitation of cell injury. This new measure of toxicity was shown to correlate very well with LDH leakage from the cells, which is a well accepted measure of cell injury. The leakage of 5'-(/sup 14/C)AMP also correlated very well with the reduction of cell ATP in cardiac myocytes. This method has been used for monitoring drug-induced toxicity in liver cells, cardiac myocytes, and LB cells.

    Biosurfactant rhamnolipids have been claimed to show biological activities of inhibiting the proliferation of cancer cells. In this study, the cytotoxicity of rhamnolipids was examined on four cancer cells (HepG2, Caco-2, Hela, MCF-7 cells) and two normal cells (HK-2 cell, primary hepatocyte). Interestingly, both cancer cells and normal cells exhibited similar sensitivities to the addition of rhamnolipids in culture medium, and the cytotoxicity was largely attenuated by the presence of fetal bovine serum (FBS) in culture medium. In correlation of the mono-/di-rhamnolipid cytotoxicity with the surface tension of culture medium, it was found that rhamnolipids triggered cytotoxicity whenever the surface tension of culture medium decreased below 41 mN/m irrespective of the FBS content in culture medium, cell line, or rhamnolipid congener. Similarly, each chemical surfactant (Tween-80, sodium dodecyl sulfate, and sodium dodecyl benzene sulfonate) could cause cytotoxicity on HepG2 cells whenever its addition made the surface tension under 41 mN/m in culture medium with or without the presence of FBS. It seems that rhamnolipids, like chemical surfactants, exhibited cytotoxicity by reducing the surface tension of culture medium rather than by changing its specific molecular structure, which had no selection on tumor cells. This study could offer helps to correct the misleading biological activity of rhamnolipids and to avoid the possible large wastes of time and expenses on developing the applications in antitumor drugs.

    Poliovirus is a recognized surrogate for norovirus, pathogen in water and food, due to the structural and genetic similarity. Although radiation sensitivity of poliovirus in water or media had been reported, there has been no research in food model such as shellfish. In this study, oyster (Crassostrea gigas) was incubated in artificial seawater contaminated with poliovirus, and thus radiation sensitivity of poliovirus was determined in inoculated oyster. The effects of ionizing radiation on the sensitivity of poliovirus were also evaluated under different conditions such as pH (4-7) and salt concentration (1-15%) in culture broth, and temperature during irradiation. The D{sub 10} value of poliovirus in PBS buffer, virus culture broth and oyster was determined to 0.46, 2.84 and 2.94 kGy, respectively. The initial plaque forming unit (PFU) of poliovirus in culture broth was slightly decreased as the decrease of pH and the increase of salt concentration, but radiation sensitivity was not affected by pH and salt contents. However, radiation resistance of poliovirus was increased at frozen state. These results provide the basic information for the inactivation of pathogenic virus in foods by using irradiation.

    Fosprenil suppressed the multiplication of cattle diarrhea virus in calf coronary vessel cell culture. Added to the culture of infected cells in a dose of 200 mg, the drug decreased the virus titer 30-fold in comparison with infected control cultures. Antiviral activity of fosprenil towards infective rhinotracheitis virus multiplication was still higher: in a dose of 100 mg it decreased the virus titer in fetal calf lung culture 100-fold in comparison with the control. Moreover, the cytopathogenic effects of the viruses in infected cultures were 24-48 h delayed under the effect of fosprenil in comparison with infected control cultures. These results recommend fosprenil for the treatment of cattle viral diseases.

    Arsenic trioxide (arsenite, As(III)) has shown a remarkable clinical efficacy, whereas its side effects are still a serious concern. Therefore, it is critical to understand the effects of As(III) on human-derived normal cells for revealing the mechanisms underlying these side effects. We examined the effects of As(III) on primary cultured chorion (C) and amnion (A) cells prepared from human fetal membranes. A significant dose-dependent As(III)-mediated cytotoxicity was observed in the C-cells accompanied with an increase of lactate dehydrogenase (LDH) release. Higher concentrations of As(III) were required for the A-cells to show cytotoxicity and LDH release, suggesting that the C-cells were more sensitive to As(III) than the A-cells. The expression levels of aquaporin 9 (AQP9) were approximately 2 times higher in the C-cells than those in the A-cells. Both intracellular arsenic accumulation and its cytotoxicity in the C-cells were significantly abrogated by sorbitol, a competitive AQP9 inhibitor, in a dose-dependent manner. The protein expression levels of multidrug resistance-associated protein (MRP) 2 were downregulated by As(III) in the C-cells, but not in the A-cells. No significant differences in the expression levels of MRP1 were observed between C- and A-cells. The protein expression of P-glycoprotein (P-gp) was hardly detected in both cells, although a detectable amount of its mRNA was observed. Cyclosporine A, a broad-spectrum inhibitor for ABC transporters, and MK571, a MRP inhibitor, but not PGP-4008, a P-gp specific inhibitor, potently sensitized both cells to As(III)-mediated cytotoxicity. These results suggest that AQP9 and MRP2 are involved in controlling arsenic accumulation in these normal cells, which then contribute to differential sensitivity to As(III) cytotoxicity between these cells.

    Diabetes self-management education can improve outcomes in adults with Type 2 diabetes mellitus (T2DM). However, Hispanics, a group that carries a large burden of disease, may not participate in diabetes education programs. Audience engagement with entertainment-education has been associated with improved health education outcomes and may engage and empower Hispanic users to active self-care. Successful use of entertainment-education relies on the use of characters and situations with whom the viewers can feel some sense of involvement and for Hispanic audiences is encouraged when storylines and characters are culturally sensitive. In this study, we used a mixed methods approach that included descriptive statistics of closed-ended and content analysis of open-ended questions to measure the cultural sensitivity of the telenovela portion of a novel technology-based application called Sugar, Heart, and Life (SHL). Specifically, we analyzed the responses of 123 male and female patients diagnosed with uncontrolled T2DM to determine viewer involvement with characters and situations in the telenovela, viewer perceived self-efficacy in following recommendations, as well as viewer satisfaction with the program. Our findings indicate that the SHL application achieved its goal of creating a user-friendly program that depicted realistic, culturally sensitive characters and storylines that resonated with Hispanic audiences and ultimately fostered perceived self-efficacy related to following recommendations given about healthy lifestyle changes for diabetes self-management. These findings suggest that the SHL application is a culturally sensitive health education intervention for use by Hispanic male and female individuals that may empower them in self-management of T2DM.

    Full Text Available Hemin is a breakdown product of hemoglobin. It has been reported that the injection of hemin improves lipid metabolism and insulin sensitivity in various genetic models. However, the effect of hemin supplementation in food on lipid metabolism and insulin sensitivity is still unclear, and whether hemin directly affects cellular insulin sensitivity is yet to be elucidated. Here we show that hemin enhances insulin-induced phosphorylation of insulin receptors, Akt, Gsk3β, FoxO1 and cytoplasmic translocation of FoxO1 in cultured primary hepatocytes under insulin-resistant conditions. Furthermore, hemin diminishes the accumulation of triglyceride and increases in free fatty acid content in primary hepatocytes induced by palmitate. Oral administration of hemin decreases body weight, energy intake, blood glucose and triglyceride levels, and improves insulin and glucose tolerance as well as hepatic insulin signaling and hepatic steatosis in male mice fed a high-fat diet. In addition, hemin treatment decreases the mRNA and protein levels of some hepatic genes involved in lipogenic regulation, fatty acid synthesis and storage, and increases the mRNA level and enzyme activity of CPT1 involved in fatty acid oxidation. These data demonstrate that hemin can improve lipid metabolism and insulin sensitivity in both cultured hepatocytes and mice fed a high-fat diet, and show the potential beneficial effects of hemin from food on lipid and glucose metabolism.

    Arsenic trioxide (arsenite, As{sup III}) has shown a remarkable clinical efficacy, whereas its side effects are still a serious concern. Therefore, it is critical to understand the effects of As{sup III} on human-derived normal cells for revealing the mechanisms underlying these side effects. We examined the effects of As{sup III} on primary cultured chorion (C) and amnion (A) cells prepared from human fetal membranes. A significant dose-dependent As{sup III}-mediated cytotoxicity was observed in the C-cells accompanied with an increase of lactate dehydrogenase (LDH) release. Higher concentrations of As{sup III} were required for the A-cells to show cytotoxicity and LDH release, suggesting that the C-cells were more sensitive to As{sup III} than the A-cells. The expression levels of aquaporin 9 (AQP9) were approximately 2 times higher in the C-cells than those in the A-cells. Both intracellular arsenic accumulation and its cytotoxicity in the C-cells were significantly abrogated by sorbitol, a competitive AQP9 inhibitor, in a dose-dependent manner. The protein expression levels of multidrug resistance-associated protein (MRP) 2 were downregulated by As{sup III} in the C-cells, but not in the A-cells. No significant differences in the expression levels of MRP1 were observed between C- and A-cells. The protein expression of P-glycoprotein (P-gp) was hardly detected in both cells, although a detectable amount of its mRNA was observed. Cyclosporine A, a broad-spectrum inhibitor for ABC transporters, and MK571, a MRP inhibitor, but not PGP-4008, a P-gp specific inhibitor, potently sensitized both cells to As{sup III}-mediated cytotoxicity. These results suggest that AQP9 and MRP2 are involved in controlling arsenic accumulation in these normal cells, which then contribute to differential sensitivity to As{sup III} cytotoxicity between these cells. -- Highlights: Black-Right-Pointing-Pointer Examination of effect of As{sup III} on primary cultured chorion (C) and amnion

    A communication guideline that is sensitive to the local culture is influential in the process of nursing care. The Gadjah Mada nurse-client communication guideline, the "Ready-Greet-Invite-Discuss," was meant (1) to strengthen the relationship between the nurse and the client despite of socio-culturally hierarchical gap between health providers and clients in Indonesian context, (2) to provide attention to the unspoken concerns especially in the context of indirect communication which mostly using non-verbal signs and politeness etiquettes, and (3) to initiate dialog in the society which hold a more community-oriented decision making. Our aim is to compare the communication skills of nursing students who had and had not received a training using a culture-sensitive Gadjah Mada nurse-client communication guideline. This was a quasi experimental randomized control study to the fifth semester students of a nursing school at Yogyakarta, Indonesia. The intervention group was trained by the Gadjah Mada nurse-client communication guideline. Both intervention and the control group had learned general nurse-client communication guidelines. The training was 4h with role-plays, supportive information and feedback sessions. An objective-structured clinical examination (OSCE) was conducted 1week after the training, in seven stations, with seven simulated clients. Observers judged the communication skills of the students using a checklist of 5-point Likert scale, whereas simulated clients judged their satisfaction using 4-point Likert scale represented in colorful ribbons. There were significant mean differences in each domain of communication guideline observed between the trained and the control groups as judged by the teachers (p≤0.05) and simulated clients. Training using a culture-sensitive communication skills guideline could improve the communication skills of the nursing students and may increase satisfaction of the clients.

    Atrazine is an herbicide frequently detected in watercourses that can affect the phytoplankton community, thus impacting the whole food chain. This study aims, firstly, to measure the sensitivity of monocultures of the green alga Scenedemus obliquus and toxic and non-toxic strains of the cyanobacteria Microcystis aeruginosa before, during and after a 30-day acclimation period to 0.1 µM of atrazine. Secondly, the sensitivity of S. obliquus and M. aeruginosa to atrazine in mixed cultures was evaluated. Finally, the ability of these strains to remove atrazine from the media was measured. We demonstrated that both strains of M. aeruginosa had higher growth rate-based EC50 values than S. obliquus when exposed to atrazine, even though their photosynthesis-based EC50 values were lower. After being exposed to 0.1 µM of atrazine for 1 month, only the photosynthesis-based EC50 of S. obliquus increased significantly. In mixed cultures, the growth rate of the non-toxic strain of M. aeruginosa was higher than S. obliquus at high concentrations of atrazine, resulting in a ratio of M. aeruginosa to total cell count of 0.6. This lower sensitivity might be related to the higher growth rate of cyanobacteria at low light intensity. Finally, a negligible fraction of atrazine was removed from the culture media by S. obliquus or M. aeruginosa over 6 days. These results bring new insights on the acclimation of some phytoplankton species to atrazine and its effect on the competition between S. obliquus and M. aeruginosa in mixed cultures.

    Full Text Available A good theory-based tool for measuring ethical sensitivity, which is usable in different contexts, is scarce. In this study, we examined the Ethical Sensitivity Scale Questionnaire (ESSQ in line with its seven-dimension structure. The scale was presented to a sample of 556 Iranian Kurdish teachers in primary, middle, and high schools. A confirmatory factor analysis was conducted to scrutinize the original factor structure of the ESSQ. The results confirmed that the ESSQ supports a reasonable model fit to study the seven dimensions of ethical sensitivity as it was developed in the original study. However, some modifications were conducted to free high error covariance between four pairs of items in the scale. This modification increased the fit indices and thus resulted in a good model fit. In addition to examining the satiability of the ESSQ, a further analysis showed that the level of ethical sensitivity in the targeted sample was high.

    Full Text Available Privacy is an important feature of the interview interaction mainly due to its potential effect on reporting information, especially sensitive information. Here we examine the effect of third-party presence on reporting both sensitive and relatively neutral outcomes. We investigate whether the effect of third-party presence on reporting sensitive information is moderated by the respondent’s need for social conformity and the respondent’s country of residence. Three types of outcomes are investigated: behavioral, attitudinal, and relatively neutral health events. Using data from 22,070 interviews and nine countries in the cross-national World Mental Health Survey Initiative, we fit multilevel logistic regression to study reporting effects on questions about suicidal behavior and marital ratings, and contrast these with questions about having high blood pressure, asthma, or arthritis. We find that there is an effect of third-party presence on reporting sensitive information and no effect on reporting of neutral information. Further, the effect of the interview privacy setting on reporting sensitive information is moderated by the need for social conformity and the cultural setting.

    Hawthorn (Crataegus spp.) plant extract is used as a herbal alternative medicine for the prevention and treatment of various cardiovascular diseases. Recently, it was shown that hawthorn extract preparations caused negative chronotropic effects in a cultured neonatal murine cardiomyocyte assay, independent of beta-adrenergic receptor blockade. The aim of this study was to further characterize the effect of hawthorn extract to decrease the contraction rate of cultured cardiomyocytes. To test the hypothesis that hawthorn is acting via muscarinic receptors, the effect of hawthorn extract on atrial versus ventricular cardiomyocytes in culture was evaluated. As would be expected for activation of muscarinic receptors, hawthorn extract had a greater effect in atrial cells. Atrial and/or ventricular cardiomyocytes were then treated with hawthorn extract in the presence of atropine or himbacine. Changes in the contraction rate of cultured cardiomyocytes revealed that both muscarinic antagonists significantly attenuated the negative chronotropic activity of hawthorn extract. Using quinuclidinyl benzilate, L-[benzylic-4,4'-(3)H] ([(3)H]-QNB) as a radioligand antagonist, the effect of a partially purified hawthorn extract fraction to inhibit muscarinic receptor binding was quantified. Hawthorn extract fraction 3 dose-dependently inhibited [(3)H]-QNB binding to mouse heart membranes. Taken together, these findings suggest that decreased contraction frequency by hawthorn extracts in neonatal murine cardiomyocytes may be mediated via muscarinic receptor activation.

  7. Self-starvation in context: towards a culturally sensitive understanding of anorexia nervosa.

    Science.gov (United States)

    Lee, S

    1995-07-01

    Extreme forms of self-starvation can be traced across time and place, and may be construed using a variety of explanatory models. Curiously, the prevailing biomedical definition of anorexia nervosa has assigned primacy to the exclusive use of 'fat phobia' by the affected subjects to justify their diminished food intake. This paper assembles evidence to show that this culturally constructed version of fat phobic anorexia nervosa has neglected the full metaphorical significance of self-starvation and, when applied in a cross-cultural context, may constitute a category fallacy. By delegitimizing other rationales for non-eating and thereby barring subjective expressions, this regnant interpretive strategy may obscure clinicians' understanding of patients' lived experience, and even jeopardize their treatment. Nonetheless, it is a relatively simple task to attune the extant diagnostic criteria to a polythetic approach which will avert cultural parochialism in psychiatric theory and practice. As a corollary of the archival and ethnocultural study of extreme self-starvation, there is, contrary to epistemological assumptions embedded in the biomedical culture of contemporary psychiatry, no 'core psychopathology' of anorexia nervosa.

    The objective of this study was to develop a test method for determining the cytotoxicity and biocompatibility of various biomaterials that are used in orthopaedic surgery. This method is based on the use of a human bone marrow cell culture and was developed as an alternative to animal experiments. Human bone marrow cell culture has certain advantages over other cell culture models, as its results show a greater conformity with animal experimental results and clinical studies. Primary cell adherence, cell number, cell proliferation, production of extracellular matrix, cell viability and cell differentiation were used as indicative parameters of biocompatibility. After 2 weeks in culture, differences could be observed between the biomaterials with respect to these parameters. Cell numbers were greatest on the hydroxyapatite ceramic specimens, but were decreased on the titanium alloy specimens. Extracellular matrix hydroxyapatite production was high for ceramics, but reduced for titanium specimens. The polymers allowed only a few cells to adhere, and there were no signs of extracellular matrix production. The influence of biomaterials on differentiation of large numbers of cells was analysed by using flow cytophotometry. There were similar populations of T cells and monocytes on all specimens. However, extended B cell and granulocyte populations were observed with titanium and polyethylene.

    It has been suggested that cognitive behaviour therapy (CBT) needs adaptation for it to be effective for patients from collectivistic cultures, as currently CBT is underpinned by individualistic values. In prior studies we have demonstrated that CBT could be adapted for Pakistani patients in Southampton, UK, and for local populations in Pakistan. Findings from these studies suggest that CBT can be adapted for patients from collectivistic cultures using a series of steps. In this paper we focus on these steps, and the process of adapting CBT for specific groups. The adaptation process should focus on three major areas of therapy, rather than simple translation of therapy manuals. These include (1) awareness of relevant cultural issues and preparation for therapy, (2) assessment and engagement, and (3) adjustments in therapy. We also discuss the best practice guidelines that evolved from this work to help therapists working with this population. We reiterate that CBT can be adapted effectively for patients from traditional cultures. This is, however, an emerging area in psychotherapy, and further work is required to refine the methodology and to test adapted CBT.

    Delivering pediatric rehabilitation services to immigrant parents of children with disabilities requires the practice of culturally sensitive care. Few studies have examined the specific nature of culturally sensitive care in pediatric rehabilitation, especially the notions of effective communication and client engagement. Interviews were held with 42 therapists (10 social workers, 16 occupational therapists and 16 speech language pathologists) from two locations in Canada (Toronto and Quebec City). Data were analyzed using an inductive content analysis approach. Study themes included the importance and nature of effective communication and client engagement in service delivery involving immigrant parents. Participants discussed using four main types of strategies to engage immigrant parents, including understanding the family situation, building a collaborative relationship, tailoring practice to the client's situation and ensuring parents' understanding of therapy procedures. The findings illuminate the importance of effective, two-way communication in providing the mutual understanding needed by therapists to engage parents in the intervention process. The findings also richly describe the engagement strategies used by therapists. Clinical implications include recommendations for strategies for therapists to employ to engage this group of parents. Furthermore, the findings are applicable to service provision in general, as engaging families in a collaborative relationship through attention to their specific situation is a general principle of good quality, family-centered care. Implications for Rehabilitation Effective communication permeates the delivery of culturally sensitive care and provides mutual understanding, which is fundamental to client engagement. The findings illuminate the nature of "partnership" by indicating the role of collaborative therapist strategies in facilitating engagement. Four main strategies facilitate effective communication and

    Full Text Available Backround: Clostridium difficile is the most common cause of nosocomial diarrhea. It is usually a consequence of antibi­otic treatment, but sporadic cases can occur. The purpose of this study was to investigate five tissue culture monolayers sen­sitivity in detection of C. difficile-toxin. Methods: A total of 402 stool samples from patients with nosocomial diarrhea hospitalized in three hospitals of Tehran Uni­versity of Medical Sciences (TUMS were collected. The samples were cultured on a selective cycloserine cefoxitin fructose agar (CCFA and incubated in anaerobic conditions, at 37 °C for 4 days. Isolates were characterized to species level by con­ventional biochemical tests. Bacterial cytotoxicity was assayed on five tissue culture monolayers. Results: Our findings show that of the total patients, 24 toxigenic C. difficile (6% were isolated. All 24 C. difficile toxins showed cytotoxic effect at ³ 1:10 dilution on Hela, Hep2, Vero, McCoy and Mdck cells after 16, 20, 24, 24 and 30 hours, re­spectively. C. difficile toxin showed cytotoxic effect at ³ 1:100 dilutions only on Hela cell monolayer after 48 hours. Conclusion: Hela cell monolayer may be a satisfactory substitute for the detection of C. difficile toxin in clinical specimens.

    Objective: To investigate the prevalence of mycoplasma infections and the sensitivity to antibiotics among patients with nongonococcal urethritis or cervicitis (NGU) in Chongqing. Methods: 387 NGU cases with mycoplasma-positive results upon culture were analysed retrospectively. RESULTS: The majority of patients with mycoplasma infections were in the 20-40 year old age group. No significant difference was found between males and females. Ureaplasma urealyticum is the main pathogen of these NGU cases and no clear relationship between its concentration and pathogenic ability was noted. Drug sensitivity was tested against nine antibiotics; the sensitivity rates to josamycin, minocycline and doxycycline were 94.06%, 88.89% and 86.82% respectively, while the resistance rates to lincomycin, ofloxacin, azithromycin and roxthromycin were 74.94%, 42.12%, 41.60% and 40.31% in turn. Conclusions: Josamycin, minocycline and doxycycline could be used as the first choice to treat NGU with mycoplasma infections in Chongqing. It is important to select antibiotics for NGU treatment with mycoplasma infections based on the results of drug sensitivity tests.

    Full Text Available Background. There are relatively few studies published examining the sensitivity and specificity of potassium hydroxide (KOH smear and fungal culture examination of tinea pedis. Objective. To evaluate the sensitivity and specificity of KOH smear and fungal culture for diagnosing tinea pedis. Methods. A pooled analysis of data from five similarly conducted bioequivalence trials for antifungal drugs was performed. Data from 460 patients enrolled in the vehicle arms of these studies with clinical diagnosis of tinea pedis supported by positive fungal culture were analyzed 6 weeks after initiation of the study to determine the sensitivity and specificity of KOH smear and fungal culture. Results. Using clinical assessment as the gold standard, the sensitivities for KOH smear and culture were 73.3% (95% CI: 66.3 to 79.5% and 41.7% (34.6 to 49.1%, respectively. The respective specificities for culture and KOH smear were 77.7% (72.2 to 82.5% and 42.5% (36.6 to 48.6%. Conclusion. KOH smear and fungal culture are complementary diagnostic tests for tinea pedis, with the former being the more sensitive test of the two, and the latter being more specific.

    Full Text Available Spanish speakers in the United States encounter numerous communication barriers during cancer treatment. Communication-focused interventions may help Spanish speakers communicate better with healthcare providers and manage symptoms and quality of life issues (SQOL. For this study, we developed a Spanish version of the electronic self-report assessment for cancer (ESRA-C, a web-based program that helps people with cancer report, track, and manage cancer-related SQOL. Four methods were used to evaluate the Spanish version. Focus groups and cognitive interviews were conducted with 51 Spanish-speaking individuals to elicit feedback. Readability was assessed using the Fry readability formula. The cultural sensitivity assessment tool was applied by three bilingual, bicultural reviewers. Revisions were made to personalize the introduction using a patient story and photos and to simplify language. Focus group participants endorsed changes to the program in a second round of focus groups. Cultural sensitivity of the program was scored unacceptable (x¯=3.0 for audiovisual material and acceptable (x¯=3.0 for written material. Fry reading levels ranged from 4th to 10th grade. Findings from this study provide several next steps to refine ESRA-C for Spanish speakers with cancer.

    To evaluate the usefulness of culture-sensitive patient information material compared with standard translated material. Multicentre, double-blind randomised controlled trial. 37 primary care practices. 435 adult primary care patients with a migration background with unipolar depressive disorder or non-specific chronic low back pain were randomised. Patients who were unable to read in the language of their respective migration background were excluded. Sufficient data were obtained from 203 women and 106 men. The largest group was of Russian origin (202 patients), followed by those of Turkish (52), Polish (30) and Italian (25) origin. Intervention group: provision of culture-sensitive adapted material. provision of standard translated material. Primary outcome: patient-rated usefulness (USE) assessed immediately after patients received the material. patient-rated usefulness after 8 weeks and 6 months, symptoms of depression (PHQ-9), back pain (Back Pain Core Set) and quality of life (WHO-5) assessed at all time points. Usefulness was found to be significantly higher (t=1.708, one-sided p=0.04) in the intervention group (USE-score=65.08, SE=1.43), compared with the control group (61.43, SE=1.63), immediately after patients received the material, in the intention-to-treat analysis, with a mean difference of 3.65 (one-sided 95% lower confidence limit=0.13). No significant differences were found for usefulness at follow-up (p=0.16, p=0.71). No significant effect was found for symptom severity in depression (p=0.95, p=0.66, p=0.58), back pain (p=0.40, p=0.45, p=0.32) or quality of life (p=0.76, p=0.86, p=0.21), either immediately after receiving the material, or at follow-up (8 weeks; 6 months). Patients with a lower level of dominant society immersion benefited substantially and significantly more from the intervention than patients with a high level of immersion (p=0.005).

  19. Kant, Xunzi and the Artificiality of Manners

    Full Text Available Both Chinese and Western philosophers have argued for the ethical importance of manners. Their approaches are sometimes criticized on the grounds that manners are artificial. I compare Xunzi’s and Kant’s responses to this claim, and discuss the relevance of both positions for the development of a theory of manners. I show that there is no single artificiality claim, but rather four different claims: the claim that polite behavior lacks spontaneity, the claim that it is insincere, the claim that it goes against human nature, and the claim that it is arbitrary. While Kant is mainly concerned with the insincerity claim, Xunzi focusses on the claim that manners are arbitrary rules. Because of their different understandings of the function of manners both authors only provide a partial answer to the artificiality claim. To arrive at a full account of manners both perspectives must be combined.

    We investigated the sensitivity of intrahepatic cholangiocarcinoma (IHCCA) subtypes to chemotherapeutics and molecular targeted agents. Primary cultures of mucin- and mixed-IHCCA were prepared from surgical specimens (N. 18 IHCCA patients) and evaluated for cell proliferation (MTS assay) and apoptosis (Caspase 3) after incubation (72 hours) with increasing concentrations of different drugs. In vivo, subcutaneous human tumor xenografts were evaluated. Primary cultures of mucin- and mixed-IHCCA were characterized by a different pattern of expression of cancer stem cell markers, and by a different drug sensitivity. Gemcitabine and the Gemcitabine-Cisplatin combination were more active in inhibiting cell proliferation in mixed-IHCCA while Cisplatin or Abraxane were more effective against mucin-IHCCA, where Abraxane also enhances apoptosis. 5-Fluoracil showed a slight inhibitory effect on cell proliferation that was more significant in mixed- than mucin-IHCCA primary cultures and, induced apoptosis only in mucin-IHCCA. Among Hg inhibitors, LY2940680 and Vismodegib showed slight effects on proliferation of both IHCCA subtypes. The tyrosine kinase inhibitors, Imatinib Mesylate and Sorafenib showed significant inhibitory effects on proliferation of both mucin- and mixed-IHCCA. The MEK 1/2 inhibitor, Selumetinib, inhibited proliferation of only mucin-IHCCA while the aminopeptidase-N inhibitor, Bestatin was more active against mixed-IHCCA. The c-erbB2 blocking antibody was more active against mixed-IHCCA while, the Wnt inhibitor, LGK974, similarly inhibited proliferation of mucin- and mixed-IHCCA. Either mucin- or mixed-IHCCA showed high sensitivity to nanomolar concentrations of the dual PI3-kinase/mTOR inhibitor, NVP-BEZ235. In vivo, in subcutaneous xenografts, either NVP-BEZ235 or Abraxane, blocked tumor growth. In conclusion, mucin- and mixed-IHCCA are characterized by a different drug sensitivity. Cisplatin, Abraxane and the MEK 1/2 inhibitor, Selumetinib were more

  3. Enhancing plant regeneration in tissue culture: a molecular approach through manipulation of cytokinin sensitivity.

    Micropropagation is used for commercial purposes worldwide, but the capacity to undergo somatic organogenesis and plant regeneration varies greatly among species. The plant hormones auxin and cytokinin are critical for plant regeneration in tissue culture, with cytokinin playing an instrumental role in shoot organogenesis. Type-B response regulators govern the transcriptional output in response to cytokinin and are required for plant regeneration. In our paper published in Plant Physiology, we explored the functional redundancy among the 11 type-B Arabidopsis response regulators (ARRs). Interestingly, we discovered that the enhanced expression of one family member, ARR10, induced hypersensitivity to cytokinin in multiple assays, including callus greening and shoot induction of explants. Here we 1) discuss the hormone dependence for in vitro plant regeneration, 2) how manipulation of the cytokinin response has been used to enhance plant regeneration, and 3) the potential of the ARR10 transgene as a tool to increase the regeneration capacity of agriculturally important crop plants. The efficacy of ARR10 for enhancing plant regeneration likely arises from its ability to transcriptionally regulate key cytokinin responsive genes combined with an enhanced protein stability of ARR10 compared with other type-B ARRs. By increasing the capacity of key tissues and cell types to respond to cytokinin, ARR10, or other type-B response regulators with similar properties, could be used as a tool to combat the recalcitrance of some crop species to tissue culture techniques.

    Methylamine (MA), a component of serum and a metabolite of nicotine and certain insecticides and herbicides, is metabolized by semicarbazide-sensitive amine oxidase (SSAO). MA is toxic to cultured human umbilical vein and calf pulmonary artery endothelial cells. Endothelial cells, which do not exhibit endogenous SSAO activity, are exposed to SSAO circulating in serum. In contrast, vascular smooth muscle cells (VSMC) do exhibit innate SSAO activity both in vivo and in vitro. This property, together with the critical localization of VSMC within the arterial wall, led us to investigate the potential toxicity of MA to VSMC. Cultured rat VSMC were treated with MA (10-5 to 1 M). In some cultures, SSAO was selectively inhibited with semicarbazide or MDL-72145 [(E)-2-(3,4-dimethoxyphenyl)-3-fluoroallylamine]. Cytotoxicity was measured via MTT, vital dye exclusion, and clonogenic assays. MA proved to be toxic to VSMC only at relatively high concentrations (LC(50) of 0.1 M). The inhibition of SSAO with semicarbazide or MDL-72145 did not increase MA toxicity, suggesting that the production of formaldehyde via tissue-bound, SSAO-mediated MA metabolism does not play a role in the minimal toxicity observed in isolated rat VSMC. The omission of fetal calf serum (FCS), which contains high SSAO activity, from media similarly showed little effect on cytotoxicity. We conclude that VSMC--in contrast to previous results in endothelial cells--are relatively resistant to MA toxicity, and SSAO does not play a role in VSMC injury by MA.

  5. Reduction in porphyrin excretion as a sensitive indicator of lead toxicity in primary cultures of adult rat hepatocytes.

    Alterations of specific metabolic pathways can be used as sensitive indicators of toxicity by chemicals and can give valuable information on the mechanism(s) involved. Short-term effects of lead on hepatic haem biosynthesis were studied in an in vitro system. Primary cultures of adult rat hepatocytes were exposed for 24-48 hr to lead (0.024-3.6 mm), and excreted and intracellular porphyrins were measured in untreated and lead-treated cultures. Cytotoxicity, as estimated by enzyme leakage, and morphological alterations were also evaluated. Control hepatocytes produced porphyrins at a rate of 387 pmol/mg cellular protein/day. Most of the released and intracellular porphyrins were protoporphyrins, although uro- and coproporphyrins were also detected in lower amounts. After 24 hr of exposure to 0.1-3.6 mm Pb(2+) , excreted porphyrins decreased by 24-92% and intracellular porphyrins by 36-60%, while 48 hr of exposure to 0.024-3.6 mm Pb(2+) caused a progressive reduction of 77-97% in porphyrin excretion and of 49-67% in intracellular porphyrins. Lead exposure also produced a differential decrease of proto-, copro- and uro-porphyrin excretion. These lead effects can be explained mainly by inhibition of the enzyme 5-aminolaevulinate dehydratase, resulting in a decreased monopyrrole supply for porphyrin biosynthesis, and probably by inhibition of the enzyme uroporphyrinogen decarboxylase. Morphological alterations and enzyme leakage were detected only after 24 hr of exposure to 2.4 mm and 48 hr of exposure to 3.6 mm Pb(2+), respectively. The results show that changes in porphyrin production, and particularly in their excretion, in cultured rat hepatocytes are useful indicators of lead toxicity, since they are more sensitive than enzyme leakage and can give preliminary information on the enzyme(s) that could be affected. They also suggest the potential benefits of the use of this method for the evaluation of compounds that alter haem biosynthesis.

    Size exclusion chromatography (SEC) is widely used in the characterization and quality control of therapeutic proteins to detect aggregates. Aggregation is a carefully monitored quality attribute from the earliest stages of clinical development owing to the possibility of eliciting an immunogenic response in the patient. During early stage molecule assessment for cell culture production, small-scale screening experiments are performed to permit rapid turn-around of results so as to not delay timelines. We report the development of a capillary SEC methodology for preliminary molecule assessment to support the evaluation of therapeutic candidates at an early stage of development. By making several key modifications to a commercially available liquid chromatography system, we demonstrate a platform process to perform capillary SEC with excellent precision, picogram sensitivity and good ruggedness. The limit of quantitation was determined to be approximately 15 pg; picogram sensitivity for SEC analysis of monoclonal antibodies had not been achieved prior to this work. In addition, we have developed a method to capture low levels of antibody (1 μg/mL) from harvested cell culture fluid (HCCF) for capillary SEC analysis. Up to 40% recovery efficiency was achieved using this micro-recovery method on 3 mL HCCF samples. Using early stage cell culture transient transfection samples, which typically have much lower titers than stable cell line samples, we demonstrate a consistent method for analyzing aggregates in low protein concentration HCCF samples for molecule assessment and early stage candidate screening.

    The advent of Web 3.0, claiming for personalization in interactive systems (Lassila & Hendler, 2007), and the need for systems capable of interacting in a more natural way in the future society flooded with computer systems and devices (Harper et al., 2008) show that great advances in HCI should be done. This chapter presents some contributions of LIA for the future of HCI, defending that using common sense knowledge is a possibility for improving HCI, especially because people assign meaning to their messages based on their common sense and, therefore, the use of this knowledge in developing user interfaces can make them more intuitive to the end-user. Moreover, as common sense knowledge varies from group to group of people, it can be used for developing applications capable of giving different feedback for different target groups, as the applications presented along this chapter illustrate, allowing, in this way, interface personalization taking into account cultural issues. For the purpose of using com...

    The paper describes the construction and initial evaluation of the new Tucker-Culturally Sensitive Health Care Inventory (T-CSHCI) Provider Form, which was developed to address the shortcomings of existing similar measures. Two hundred seventeen (217) 3rd and 4th year medical students completed the T-CSHCI-Provider Form. Factor analysis was used to identify non-overlapping items. The final solution produced five factors: patient-centeredness, interpersonal skills, disrespect/disempowerment, competence, and cultural knowledge/responsiveness. The five T-CSHCI-Provider Form factors/subscales proved to be reliable and were associated with related constructs as hypothesized. This study provides initial evidence that the T-CSHCI-Provider Form measures independent dimensions of patient-centered culturally sensitive health care as perceived by medical students. Recommendations for ways in which the T-CSHCI Provider Form can be used to guide culturally sensitive health care training are provided.

    The epistemological gap between the medical reality of mental health practitioners and the sacred reality of their Jewish ultra-orthodox patients poses a major challenge for therapy. Based on our work with psychiatric patients from the ultra-orthodox community of northern Jerusalem, we propose a set of guidelines to cope with this challenge. Basically, we seek to incorporate religiously congruent elements, composed of metaphoric images, narratives and actions, into the wide range of our "secular" treatment modalities in order to respond to the patient's suffering, often expressed through distinctively religious idioms of distress. This endeavor calls for "a temporary suspension of disbelief" on both sides. The guidelines presented include three sets of factors which appear pertinent to working with ultra-orthodox patients. The first set is contextual in nature, dealing with the image of the clinic and its physical setting; the second discusses the necessary role requisites of the therapists; and the third one, accorded a central importance, deals on various levels with the therapeutic interventions administered in terms of form and content. Several case vignettes are presented to illustrate three classes of religiously informed interventions: healing rituals, dream interpretation, and the use of culturally congruent metaphors and stories. In the concluding part we discuss ethical and instrumental issues that the proposed therapeutic guidelines may raise.

    European folk medicine has a long and vibrant history, enriched with the various documented uses of local and imported plants and plant products that are often unique to specific cultures or environments. In this paper, we consider the medicoethnobotanical field studies conducted in Europe over the past two decades. We contend that these studies represent an important foundation for understanding local small-scale uses of CAM natural products and allow us to assess the potential for expansion of these into the global market. Moreover, we discuss how field studies of this nature can provide useful information to the allopathic medical community as they seek to reconcile existing and emerging CAM therapies with conventional biomedicine. This is of great importance not only for phytopharmacovigilance and managing risk of herb-drug interactions in mainstream patients that use CAM, but also for educating the medical community about ethnomedical systems and practices so that they can better serve growing migrant populations. Across Europe, the general status of this traditional medical knowledge is at risk due to acculturation trends and the urgency to document and conserve this knowledge is evident in the majority of the studies reviewed.

    Most student work as research assistants occurs at the graduate level of nursing education, and little is known about the role of undergraduate students as research assistants (RAs) in major research projects. Based on our desire to study Mexican American (MA) cancer caregivers, we needed bilingual and bicultural RAs to serve as data collectors with women who spoke Spanish and possessed cultural beliefs that influenced their caregiving. Following successful recruitment, orientation, and mentoring based on Bandura's social learning theory [Bandura, A., 2001. Social learning theory: an agentic perspective. Annual Review of Psychology 52, 1-26] and accepted teaching-learning principles, RAs engaged in various behaviors that facilitated study outcomes. Faculty researchers, RAs, and study participants benefitted greatly from the undergraduate student involvement in this project. This article describes successful student inclusion approaches, ongoing faculty-RA interactions, and lessons learned from the research team experience. Guidelines discussed support the potential for making the undergraduate RA role a useful and unique learning experience.

    The productivity of mammalian cells can be enhanced by facilitating adequate oxygen transfer into the cultivation medium. However, current methods of controlling dissolved oxygen (DO) fail to account for alterations in medium composition during the course of the fermentation. These changes, which directly affect gas solubility and overall mass transfer coefficient, may be significant and deteriorate controller's performance in the long run. In this paper, the applications of Generalized Predictive Controllers (GPC) to DO control were investigated in a shear sensitive environment and compared to PID and Model Predictive Controllers (MPC). Input and output data for system identification were initially generated by varying the composition of oxygen fed into the bioreactor from 0 to 0.21 mol % while keeping the total inlet gas flow rate at 8.75 vvm. The process was identified using an AutoRegressive model with eXogeneous inputs (ARX) model and tested on different data sets. The model parameters were then correlated with the overall mass transfer coefficients. In simulation tests, the output of the PID controller switched from minimum to maximum values while more continuous control signals were obtained with the MPC and GPC controllers. When tested in a cell-free medium, all three controllers were able to track setpoint changes with some chattering observed in the control signals. The GPC outperformed the MPC and PID controllers when applied to the cultivation of hybridoma cells.

    Full Text Available In the progress of allergic and irritant contact dermatitis, chemicals that cause the generation of reactive oxygen species trigger a heat shock response in keratinocytes. In this study, an optical sensor cell line based on cultured human keratinocytes (HaCaT cells expressing green fluorescent protein (GFP under the control of the stress-inducible HSP70B’ promoter were constructed. Exposure of HaCaT sensor cells to 25 µM cadmium, a model substance for oxidative stress induction, provoked a 1.7-fold increase in total glutathione and a ~300-fold induction of transcript level of the gene coding for heat shock protein HSP70B’. An extract of Arnica montana flowers resulted in a strong induction of the HSP70B’ gene and a pronounced decrease of total glutathione in keratinocytes. The HSP70B’ promoter-based sensor cells conveniently detected cadmium-induced stress using GFP fluorescence as read-out with a limit of detection of 6 µM cadmium. In addition the sensor cells responded to exposure of cells to A. montana extract with induction of GFP fluorescence. Thus, the HaCaT sensor cells provide a means for the automated detection of the compromised redox status of keratinocytes as an early indicator of the development of human skin disorders and could be applied for the prediction of skin irritation in more complex in vitro 3D human skin models and in the development of micro-total analysis systems (µTAS that may be utilized in dermatology, toxicology, pharmacology and drug screenings.

    Patients with low literacy, low numeracy, and/or linguistic needs can experience challenges understanding diabetes information and applying concepts to their self-management. The authors designed a toolkit of education materials that are sensitive to patients' literacy and numeracy levels, language preferences, and cultural norms and that encourage shared goal setting to improve diabetes self-management and health outcomes. The Partnership to Improve Diabetes Education (PRIDE) toolkit was developed to facilitate diabetes self-management education and support. The PRIDE toolkit includes a comprehensive set of 30 interactive education modules in English and Spanish to support diabetes self-management activities. The toolkit builds upon the authors' previously validated Diabetes Literacy and Numeracy Education Toolkit (DLNET) by adding a focus on shared goal setting, addressing the needs of Spanish-speaking patients, and including a broader range of diabetes management topics. Each PRIDE module was evaluated using the Suitability Assessment of Materials (SAM) instrument to determine the material's cultural appropriateness and its sensitivity to the needs of patients with low literacy and low numeracy. Reading grade level was also assessed using the Automated Readability Index (ARI), Coleman-Liau, Flesch-Kincaid, Fry, and SMOG formulas. The average reading grade level of the materials was 5.3 (SD 1.0), with a mean SAM of 91.2 (SD 5.4). All of the 30 modules received a "superior" score (SAM >70%) when evaluated by 2 independent raters. The PRIDE toolkit modules can be used by all members of a multidisciplinary team to assist patients with low literacy and low numeracy in managing their diabetes. © 2015 The Author(s).

    The purpose of this study was to translate pain sensitivity questionnaires (PSQ) into the Korean language, perform a cross-cultural adaption of the PSQ, and validate the Korean version of PSQ in patients with degenerative spinal disease. The PSQ was translated forward and backward, cross-culturally adapted by 2 independent translators, and approved by an expert committee. The final Korean version of the PSQ was tested on 72 patients with degenerative spinal disease. Test-retest reliability was evaluated for 60 patients (83%) who completed the second assessment in an interval of 4 weeks. The mean PSQ-minor, PSQ-moderate, and PSQ-total (standard deviation [SD]) were 5.40 (2.02), 6.46 (1.98), and 5.93 (1.93), respectively. The PSQ-total, PSQ-minor, and PSQ-moderate of the Korean version showed very good internal consistencies determined by the Cronbach's α of 0.926, 0.869, and 0.877, respectively. For convergent validity, the PSQ scores of the Korean version showed significant correlations with pain catastrophizing scale (PCS) (r = 0.377, P = 0.002; r = 0.365, P = 0.003; r = 0.362, P = 0.003 for PSQ-total, PSQ-minor, and PSQ-moderate of the Korean version, respectively). For test-retest reliability, the intraclass correlation coefficients were 0.782 for PSQ-total, 0.752 for PSQ-minor, and 0.793 for PSQ-moderate. In conclusion, the validated Korean version of PSQ is a transculturally equivalent, reliable, and valid tool to assess individual pain sensitivity. © 2013 World Institute of Pain.

    David Metzgar

    Full Text Available Bloodstream infection (BSI and sepsis are rising in incidence throughout the developed world. The spread of multi-drug resistant organisms presents increasing challenges to treatment. Surviving BSI is dependent on rapid and accurate identification of causal organisms, and timely application of appropriate antibiotics. Current culture-based methods used to detect and identify agents of BSI are often too slow to impact early therapy and may fail to detect relevant organisms in many positive cases. Existing methods for direct molecular detection of microbial DNA in blood are limited in either sensitivity (likely the result of small sample volumes or in breadth of coverage, often because the PCR primers and probes used target only a few specific pathogens. There is a clear unmet need for a sensitive molecular assay capable of identifying the diverse bacteria and yeast associated with BSI directly from uncultured whole blood samples. We have developed a method of extracting DNA from larger volumes of whole blood (5 ml per sample, amplifying multiple widely conserved bacterial and fungal genes using a mismatch- and background-tolerant PCR chemistry, and identifying hundreds of diverse organisms from the amplified fragments on the basis of species-specific genetic signatures using electrospray ionization mass spectrometry (PCR/ESI-MS. We describe the analytical characteristics of the IRIDICA BAC BSI Assay and compare its pre-clinical performance to current standard-of-care methods in a collection of prospectively collected blood specimens from patients with symptoms of sepsis. The assay generated matching results in 80% of culture-positive cases (86% when common contaminants were excluded from the analysis, and twice the total number of positive detections. The described method is capable of providing organism identifications directly from uncultured blood in less than 8 hours.The IRIDICA BAC BSI Assay is not available in the United States.

    Studies of the primary cultures of granulocytes, mononuclear, and monocyte-macrophage cells derived from human blood were performed using variola virus (VARV) in the doses of 0.001-0.021 PFU/cell (plaques-forming units per cell). Positive dynamics of the virus accumulation was observed only in the monocyte-macrophages with maximum values of virus concentration (5.0-5.5 Ig PFU/ml) mainly within six days after the infection. The fact of VARV replication in the monocyte-macrophages was confirmed by the data of electron microscopy. At the same time, virus vaccines when tested in doses 3.3 and 4.2 Ig PFU/ml did not show the ability to reproduce in these human cells. The people sensitivity to VARV as assessed from the data obtained on human monocyte-macrophages corresponded to -1 PFU (taking into account the smooth interaction of the virus in the body to the cells of this type), which is consistent to previously found theoretical data on the virus sensitivity. The human susceptibility to VARV assessed experimentally can be used to predict the adequacy of developed smallpox models (in vivo) based on susceptible animals. This is necessary for reliable assessment of the efficiency of development of drugs for treatment and prophylaxis of the smallpox.

    A manner of death may be ruled undetermined by the forensic pathologist when there is insufficient information about the circumstances surrounding the death to make a ruling. The aim of our study was to retrospectively analyze a series of autopsy cases that were classified as undetermined manner of death after complete investigations. In all, 48 cases were examined. In 23 cases (48%), the cause of death was determined. The most frequent cause of death was toxic death (n = 11). More than one manner of death was deemed conceivable for most cases (n = 39). The most frequent and the most probable manner of death was accident (n = 37). Homicide was not excluded in about 23% of the cases. Our study showed that the manner of death may remain undetermined despite an established cause of death, and even when two or more conceivable causes of death are considered. Our study pointed out that undetermined manner of death covers a wide range of situations and that homicide may be underestimated. © 2015 American Academy of Forensic Sciences.

  3. Introduction of culturally sensitive HIV prevention in the context of female initiation rites: an applied anthropological approach in Mozambique.

    In Mozambique, initiation rites represent the most appropriate socio-cultural context for dealing with sexuality for a large part of the population. As the group most vulnerable to HIV exposure, HIV-prevention counselling could be ideally introduced to young women during initiation rites. This article demonstrates how interventions can take advantage of the positive aspects of this tradition. We discuss local notions of social 'contamination' versus biological 'contamination,' and we present a culturally sensitive communication strategy to bridge the divergent paradigms around AIDS-similar symptoms. Because of the emotional importance of the initiation rites, the suggested approach goes far beyond cognitive knowledge. After training, the godmothers in initiation rites became highly motivated to teach novice girls about HIV prevention and they trained other elderly women as well. Thus, the initiation rites turned into a process of empowerment for women in their own communities. A central agenda of the female initiation rites in Mozambique is to inculcate respect towards ancestors, elders, authorities and others; however, this respectful attitude between genders and between generations is disappearing due to factors like warfare and the cash economy. HIV-prevention counselling may be successfully introduced into initiation rites because of the unconscious, emotional impact of the process on the initiates' behaviour. Other studies have shown that cognitive knowledge is not enough to lead to behavioural changes. Without changing the traditional initiation rites for females, which in Mozambique includes no genital cutting, a complementary approach introduces HIV-prevention counselling during ritual counselling moments, thereby motivating godmothers and novice girls and young women to be more aware and take precautions to prevent HIV infection.

    The United States is ethnically diverse. This diversity presents challenges to nurses, who, without empirical evidence to design culturally congruent interventions, may contribute to mental health care disparities. Using Leininger's theory of culture care diversity and universality, this study documented communication and interaction patterns of ethnically diverse, urban, impoverished, and underserved women. Using a community-based participatory research framework, 61 Black, Hispanic, and White women participated in focus groups around their experiences with anxiety/depression. Researchers recorded verbal communication, nonverbal behavior, and patterns of interaction. The women's communication and interaction patterns gave evidence of three themes that were evident across all focus groups and five subthemes that emerged along ethnic lines. The results suggest cultural universalities and cultural uniquenesses relative to the communication and interaction patterns of urban, ethnically diverse, impoverished, and underserved women that may assist in the design of culturally sensitive mental health care. © The Author(s) 2014.

  5. Use of sensitive, broad-spectrum molecular assays and human airway epithelium cultures for detection of respiratory pathogens.

    Full Text Available Rapid and accurate detection and identification of viruses causing respiratory tract infections is important for patient care and disease control. Despite the fact that several assays are available, identification of an etiological agent is not possible in ~30% of patients suffering from respiratory tract diseases. Therefore, the aim of the current study was to develop a diagnostic set for the detection of respiratory viruses with sensitivity as low as 1-10 copies per reaction. Evaluation of the assay using a training clinical sample set showed that viral nucleic acids were identified in ~76% of cases. To improve assay performance and facilitate the identification of novel species or emerging strains, cultures of fully differentiated human airway epithelium were used to pre-amplify infectious viruses. This additional step resulted in the detection of pathogens in all samples tested. Based on these results it can be hypothesized that the lack of an etiological agent in some clinical samples, both reported previously and observed in the present study, may result not only from the presence of unknown viral species, but also from imperfections in the detection methods used.

    Full Text Available The burden of stroke is on the rise in Nigeria. A multi-faceted strategy is essential for reducing this growing burden and includes promoting medication adherence, optimizing traditional biomarker risk targets (blood pressure, cholesterol and encouraging beneficial lifestyle practices. Successful implementation of this strategy is challenged by inadequate patient health literacy, limited patient/medical system resources, and lack of a coordinated interdisciplinary treatment approach. Moreover, the few interventions developed to improve medical care in Nigeria have generally been aimed at physicians (primarily and nurses (secondarily with minimal input from other key health care providers, and limited contributions from patients, caregivers, and the community itself. The Tailored Hospital-based Risk Reduction to Impede Vascular Events after Stroke (THRIVES study is assessing the efficacy of a culturally sensitive multidimensional intervention for controlling blood pressure in recent stroke survivors. A key component of the intervention development process was the constitution of a project task force comprising various healthcare providers and administrators. This paper describes the unique experience in Sub-Saharan Africa of utilizing of an interdisciplinary Task force to facilitate the development of the multipronged behavioral intervention aimed at enhancing stroke outcomes in a low-middle income country.

    Full Text Available Purpose: The purpose of this study was to ascertain if the simple practice of Gram stain, acridine orange stain and direct sensitivity determination of positive blood culture bottles could be used to guide early and appropriate treatment in trauma patients with clinical suspicion of sepsis. The study also aimed to evaluate the error in interpreting antimicrobial sensitivity by direct method when compared to standard method and find out if specific antibiotic-organism combination had more discrepancies. Findings from consecutive episodes of blood stream infection at an Apex Trauma centre over a 12-month period are summarized. Materials and Methods: A total of 509 consecutive positive blood cultures were subjected to Gram staining. AO staining was done in BacT/ALERT-positive Gram-stain negative blood cultures. Direct sensitivity was performed from 369 blood culture broths, showing single type of growth in Gram and acridine orange staining. Results of direct sensitivity were compared to conventional sensitivity for errors. Results: No ′very major′ discrepancy was found in this study. About 5.2 and 1.8% minor error rates were noted in gram-positive and gram-negative bacteria, respectively, while comparing the two methods. Most of the discrepancies in gram-negative bacteria were noted in β lactam - β lactamase inhibitor combinations. Direct sensitivity testing was not reliable for reporting of methicillin and vancomycin resistance in Staphylococci. Conclusions: Gram stain result together with direct sensitivity testing is required for optimizing initial antimicrobial therapy in trauma patients with clinical suspicion of sepsis. Gram staining and AO staining proved particularly helpful in the early detection of candidaemia.

    The early stages of insulin-dependent diabetes mellitus are characterized by a selective inability to secrete insulin in response to glucose, coupled to a better response to nonnutrient secretagogues. The deficient glucose response may be a result of the autoimmune process directed toward the beta-cells. Interleukin-1 (IL-1) has been suggested to be one possible mediator of immunological damage of the beta-cells. In the present study we characterized the sensitivity of beta-cells to different secretagogues after human recombinant IL-1 beta (rIL-1 beta) exposure. Furthermore, experiments were performed to clarify the biochemical mechanisms behind the defective insulin response observed in these islets. Rat pancreatic islets were isolated and kept in tissue culture (medium RPMI-1640 plus 10% calf serum) for 5 days. The islets were subsequently exposed to 60 pM human recombinant IL-1 beta during 48 h in the same culture conditions as above and examined immediately after IL-1 exposure. The rIL-1 beta-treated islets showed a marked reduction of glucose-stimulated insulin release. Stimulation with arginine plus different glucose concentrations, and leucine plus glutamine partially counteracted the rIL-1 beta-induced reduction of insulin release. The activities of the glycolytic enzymes hexokinase, glucokinase, and glyceraldehyde 3-phosphate dehydrogenase, were similar in control and IL-1-exposed islets. Treatment with IL-1 also did not impair the activities of NADH+- and NADPH+-dependent glutamate dehydrogenase, glutamate-aspartate transaminase, glutamate-alanine transaminase, citrate synthase, and NAD+-linked isocitrate dehydrogenase. The oxidation of D-[6-14C]glucose and L-[U-14C]leucine were decreased by 50% in IL-1-treated islets. Furthermore, there was a significant decrease in the ratios of [2-14C]pyruvate oxidation/[1-14C]pyruvate decarboxylation and L-[U-14C]leucine oxidation/L-[1-14C]leucine decarboxylation, indicating that IL-1 decreases the proportion of

    Time-delay dynamical systems, which depend on both the current state of the system and the state at delayed times, have been an active area of research in many real-world applications. In this paper, we consider a nonlinear time-delay dynamical system of dha-regulonwith unknown time-delays in batch culture of glycerol bioconversion to 1,3-propanediol induced by Klebsiella pneumonia. Some important properties and strong positive invariance are discussed. Because of the difficulty in accurately measuring the concentrations of intracellular substances and the absence of equilibrium points for the time-delay system, a quantitative biological robustness for the concentrations of intracellular substances is defined by penalizing a weighted sum of the expectation and variance of the relative deviation between system outputs before and after the time-delays are perturbed. Our goal is to determine optimal values of the time-delays. To this end, we formulate an optimization problem in which the time delays are decision variables and the cost function is to minimize the biological robustness. This optimization problem is subject to the time-delay system, parameter constraints, continuous state inequality constraints for ensuring that the concentrations of extracellular and intracellular substances lie within specified limits, a quality constraint to reflect operational requirements and a cost sensitivity constraint for ensuring that an acceptable level of the system performance is achieved. It is approximated as a sequence of nonlinear programming sub-problems through the application of constraint transcription and local smoothing approximation techniques. Due to the highly complex nature of this optimization problem, the computational cost is high. Thus, a parallel algorithm is proposed to solve these nonlinear programming sub-problems based on the filled function method. Finally, it is observed that the obtained optimal estimates for the time-delays are highly satisfactory

    The dinoflagellate Karlodinium veneficum was grown in bubble column photobioreactors and a genetic algorithm-based stochastic search strategy used to find optimal values for the culture parameters gas flow rate, culture height, and nozzle sparger diameter. Cell production, concentration of reactive oxygen species (ROS), membrane fluidity and photosynthetic efficiency were studied throughout the culture period. Gas-flow rates below 0.26Lmin(-1), culture heights over 1.25m and a nozzle diameter of 1.5mm were found to provide the optimal conditions for cell growth, with an increase of 60% in cell production with respect to the control culture. Non-optimal conditions produced a sufficiently high shear stress to negatively affect cell growth and even produce cell death. Cell physiology was also severely affected in stressed cultures. The production of ROS increased by up to 200%, whereas cell membrane fluidity decreased by 60% relative to control cultures. Photosynthetic efficiency decreased concomitantly with membrane fluidity.

    Identification of new drugs and predicting drug response are major challenges in oncology, especially for brain tumors, because total surgical resection is difficult and radiation therapy or chemotherapy is often ineffective. With the aim of developing a culture system close to in vivo conditions for testing new drugs, we characterized an ex vivo three-dimensional culture system based on a hyaluronic acid-rich hydrogel and compared it with classical two-dimensional culture conditions. U87-MG glioblastoma cells and seven primary cell cultures of human glioblastomas were subjected to radiation therapy and chemotherapy drugs. It appears that 3D hydrogel preserves the original cancer growth behavior and enables assessment of the sensitivity of malignant gliomas to radiation and drugs with regard to inter-tumoral heterogeneity of therapeutic response. It could be used for preclinical assessment of new therapies. - Highlights: • We have compared primary glioblastoma cell culture in a 2D versus 3D-matrix system. • In 3D morphology, organization and markers better recapitulate the original tumor. • 3D-matrix culture might represent a relevant system for more accurate drug screening.

    Accumulating evidence suggests that several IgE clones can activate mast cells during the sensitization phase even in the absence of antigen. They were found to induce pro-inflammatory cytokine release, histamine synthesis, chemotaxis, adhesion, and accelerated maturation of mast cells, although it remains unknown whether antigen-induced responses can be affected by differences of IgE clones. We compared two IgE clones, which were different in the capacity to activate mast cells during sensitization, in terms of potentials to affect antigen-induced degranulation and cytokine releases using IL-3-dependent murine bone marrow-derived cultured mast cells (BMMCs). Antigen-induced degranulation and pro-inflammatory cytokine release were augmented, when BMMCs were sensitized with elevated concentrations of a clone IgE-3, which did not induce phosphorylation of JNK and cytokine release in the absence of antigen, whereas those were significantly rather decreased, when BMMCs were sensitized with elevated concentrations of a clone SPE-7, one of the most potent cytokinergic IgE clones, which intensively induced phosphorylation of JNK. This attenuated response with SPE-7 was accompanied by decreased tyrosine phosphorylation of the cellular proteins including Syk upon antigen stimulation. SP600125, which is known to inhibit JNK, restored the levels of antigen-induced degranulation and phosphorylation of Syk in BMMCs sensitized with higher concentrations of a clone SPE-7 when it was added before sensitization. Treatment with anisomycin, a potent activator of JNK, before IgE sensitization significantly suppressed antigen-induced degranulation. These findings suggest that differences of sensitizing IgE clones can affect antigen-induced responses and activation of JNK during sensitization might suppress antigen-induced activation of mast cells.

    2013-12-01

    Here we describe the first high-throughput amenable method of quantifying Saccharomyces cerevisiae culture viability. Current high-throughput methods of assessing yeast cell viability, such as flow cytometry and SGA analysis, do not measure the percentage viability of a culture but instead measure cell vitality or colony fitness, respectively. We developed a method, called tadpoling, to quantify the percentage viability of a yeast culture, with the ability to detect as few as one viable cell amongst ~10(8) dead cells. The most important feature of this assay is the exploitation of yeast colony formation in liquid medium. Utilizing a microtiter dish, we are able to observe a range of viability of 100% to 0.0001%. Comparison of tadpoling to the traditional plating method to measure yeast culture viability reveals that, for the majority of Saccharomyces species analyzed there is no significant difference between the two methods. In comparison to flow cytometry using propidium iodide, the high-throughput method of measuring yeast culture viability, tadpoling is much more accurate at culture viabilities viability.

    Full Text Available Abstract Background Pseudomonas aeruginosa is the major pathogen involved in the decline of lung function in cystic fibrosis (CF patients. Early aggressive antibiotic therapy has been shown to be effective in preventing chronic colonization. Therefore, early detection is important and sensitive detection methods are warranted. In this study, we used a dilution series of P. aeruginosa positive sputa, diluted in a pool of P. aeruginosa negative sputa, all from CF patients - to mimick as closely as possible the sputa sent to routine laboratories - to compare the sensitivity of three culture techniques versus that of two conventional PCR formats and four real-time PCR formats, each targeting the P. aeruginosa oprL gene. In addition, we compared five DNA-extraction protocols. Results In our hands, all three culture methods and the bioMérieux easyMAG Nuclisens protocol Generic 2.0.1, preceded by proteinase K pretreatment and followed by any of the 3 real-time PCR formats with probes were most sensitive and able to detect P. aeruginosa up to 50 cfu/ml, i.e. the theoretical minimum of one cell per PCR mixture, when taking into account the volumes used in this study of sample for DNA-extraction, of DNA-elution and of DNA-extract in the PCR mixture. Conclusion In this study, no difference in sensitivity could be found for the detection of P. aeruginosa from sputum between microbiological culture and optimized DNA-extraction and real-time PCR. The results also indicate the importance of the optimization of the DNA-extraction protocol and the PCR format.

    Full Text Available BACKGROUND: The two-step glutamate dehydrogenase antigencytotoxicity neutralization assay algorithm has been found to be reliable for the diagnosis of toxigenic Clostridium difficile. However, the high sensitivity of the screening method is compromised by the relative low sensitivity of the second step, the direct cytotoxin neutralization assay (DCNA using a fecal filtrate. The objective of the present study was to compare the DCNA with an indirect cytotoxin neutralization assay (ICNA.

    The impact of living with arthritis in a rural Mexican Mayan community along with the barriers encountered by people living with this chronic condition were investigated in this study. The community needs around this health issue were investigated by conducting an ethnographic study using data obtained during two time periods (August 2012-April 2013 and December 2013-December 2014). During the first period, fieldwork observations and interviews with 65 individuals, which included people with arthritis, health professionals, traditional health providers, and community leaders were undertaken. During the second period, 46 community meetings were conducted to identify the needs associated with arthritis in the municipality. Data were analyzed following a modified version of the Framework approach. The results show that arthritis reduces the health-related quality of life of the people in Chankom through a process of disablement, conditioning a need to access culturally sensitive healthcare. Availability, attainability, and acceptability barriers prevent access to this type of healthcare and result from power imbalance between indigenous and non-indigenous people. There is a need to develop culturally sensitive rehabilitation services for people living with arthritis in Chankom. Mayan people should be involved in the design and implementation of these services. Moreover, it is important to improve our understanding of the processes behind the healthcare access inequities identified in this study by attending to the historical generation of current social, economical, cultural, and political structures.

    Botulinum neurotoxin (BoNT) is the most lethal naturally produced neurotoxin. Due to the extreme toxicity, BoNTs are implicated in bioterrorism, while the specific mechanism of action and long-lasting effect was found to be medically applicable in treating various neurological disorders. Therefore, for both public and patient safety, a highly sensitive, physiologic, and specific assay is needed. In this paper, we show a method for achieving a highly sensitive cell-based assay for BoNT/A detection using the motor neuron-like continuous cell line NG108-15. To achieve high sensitivity, we performed a media optimization study evaluating three commercially available neural supplements in combination with retinoic acid, purmorphamine, transforming growth factor β1 (TGFβ1), and ganglioside GT1b. We found nonlinear combinatorial effects on BoNT/A detection sensitivity, achieving an EC50 of 7.4 U ± 1.5 SD (or ~7.9 pM). The achieved detection sensitivity is comparable to that of assays that used primary and stem cell-derived neurons as well as the mouse lethality assay.

  10. A voltage-sensitive dye-based assay for the identification of differentiated neurons derived from embryonic neural stem cell cultures.

    Richardson N Leão

    Full Text Available BACKGROUND: Pluripotent and multipotent stem cells hold great therapeutical promise for the replacement of degenerated tissue in neurological diseases. To fulfill that promise we have to understand the mechanisms underlying the differentiation of multipotent cells into specific types of neurons. Embryonic stem cell (ESC and embryonic neural stem cell (NSC cultures provide a valuable tool to study the processes of neural differentiation, which can be assessed using immunohistochemistry, gene expression, Ca(2+-imaging or electrophysiology. However, indirect methods such as protein and gene analysis cannot provide direct evidence of neuronal functionality. In contrast, direct methods such as electrophysiological techniques are well suited to produce direct evidence of neural functionality but are limited to the study of a few cells on a culture plate. METHODOLOGY/PRINCIPAL FINDINGS: In this study we describe a novel method for the detection of action potential-capable neurons differentiated from embryonic NSC cultures using fast voltage-sensitive dyes (VSD. We found that the use of extracellularly applied VSD resulted in a more detailed labeling of cellular processes compared to calcium indicators. In addition, VSD changes in fluorescence translated precisely to action potential kinetics as assessed by the injection of simulated slow and fast sodium currents using the dynamic clamp technique. We further demonstrate the use of a finite element model of the NSC culture cover slip for optimizing electrical stimulation parameters. CONCLUSIONS/SIGNIFICANCE: Our method allows for a repeatable fast and accurate stimulation of neurons derived from stem cell cultures to assess their differentiation state, which is capable of monitoring large amounts of cells without harming the overall culture.

    Health care workers serve diverse communities and face challenges in delivering culturally responsive EOL care, especially when caring for Latino elders. The objective of this study was to investigate the effect of a newly developed telenovela, or video soap opera, on health care professionals (HCPs)' awareness of caregivers' stress and patients' cultural approaches to end-of-life (EOL) care decisions. A multicenter cross-sectional study among three communities in New York, Miami, and Missouri. Participants from a convenience sample of multidisciplinary HCPs were randomly assigned to view power point presentation with either a control video or an intervention-telenovela about caregiving as part of a one-hour audiovisual seminar and completed a pre- and post-test questionnaire to evaluate reaction and learning. Participants (N = 142) were mostly female (80%) nurses (54%) with a mean age of 44.5 ± 12.4 years and from non-Hispanic white (41%) or Hispanics (37%) ethnicity. In both control and intervention groups, post-test responses demonstrated a high level (87%) of satisfaction with seminar and an increase in openness to discuss EOL issues with culturally diverse patients (P educate HCPs on cultural sensitivity to help ethnically diverse caregivers and their patients benefit from EOL care.

    Full Text Available The Revised Two-Factor Study Process Questionnaire (R-SPQ-2F is used to examine students' study approaches in higher education. The questionnaire assumes to measure two factors: a deep and a surface study approach. Analyses into the validity and reliability of the original English R-SPQ-2F yielded positive results. In this study, we examined the degree to which these positive results can also be found for the Dutch version that we developed. By comparing our results with the results of earlier studies in different cultures, we conclude cross-cultural sensitivity is an important point to be borne in mind when using the R-SPQ-2F. Our research supports the validity and reliability of our Dutch version of the R-SPQ-2F.

    High titers of Verotoxin (VT) were released from cell pellets of VT-producing Escherichia coli (VTEC; corresponding to E. coli strains producing "high" levels of Shiga-like toxin) after incubation in polymyxin B (0.1 mg/ml) for 30 min at 37 degrees C. Maximal titers of polymyxin-releasable VT occurred in cells obtained from 5-h Penassay broth cultures and were up to eightfold higher than the peak culture supernatant VT titers which occurred in 8-h cultures. Polymyxin-releasable cell extracts of 5-h broth cultures inoculated with mixtures of VT-positive (VT+) and VT-negative strains had easily detectable VT titers when the proportion of VT+ cells in the mixture was about 1.0%, but culture supernatants were negative for VT even when this proportion was 20%. The results were the same whether the initial inoculum consisted of broth culture mixtures of VT+ and VT-negative strains or colony sweeps (loopfuls of confluent bacterial growth) taken from solid plate media previously inoculated with the broth mixtures. In a clinical study, 80 stool cultures from patients with hemolytic uremic syndrome and family contacts with diarrhea were tested for free fecal VT, VT in polymyxin extracts of colony sweeps (VT/PECS), and VTEC (examination of 20 separate E. coli colonies from primary media for VT production). Of the 80 samples, 40 were positive for at least one of these three tests; all 40 were positive for free fecal VT, and 20 of these were positive for VT/PECS. VTEC (as few as 1 colony out of 20) were only isolated from 14 of the 20 cultures that were positive for VT/PECS. In six cases, the VT/PECS was positive even when none of 20 colonies tested were VT+, suggesting that the procedure was able to detect a proportion of VTEC that was less than one in 20(5%). We conclude that the VT/PECS method is highly sensitive for detecting low concentrations of VTEC in stools and provides a rapid method for screening out stools that are negative for VTEC. The technique should also be of

    By gating cell cycle progression to specific times of the day, the intracellular circadian clock is thought to reduce the exposure of replicating cells to potentially hazardous environmental and endogenous genotoxic compounds. Although core clock gene defects that eradicate circadian rhythmicity can cause an altered in vivo genotoxic stress response and aberrant proliferation rate, it remains to be determined to what extent these cell cycle related phenotypes are due to a cell-autonomous lack of circadian oscillations. We investigated the DNA damage sensitivity and proliferative capacity of cultured primary Cry1(-/- )|Cry2(-/-) fibroblasts. Contrasting previous in vivo studies, we show that the absence of CRY proteins does not affect the cell-autonomous DNA damage response upon exposure of primary cells in vitro to genotoxic agents, but causes cells to proliferate faster. By comparing primary wild-type, Cry1(-/-) |Cry2(-/-), Cry1(+/-)|Cry2(-/-) and Cry1(-/-)|Cry2(+/-) fibroblasts, we provide evidence that CRY proteins influence cell cycle progression in a cell-autonomous, but circadian clock-independent manner and that the accelerated cell cycle progression of Cry-deficient cells is caused by global dysregulation of Bmal1-dependent gene expression. These results suggest that the inconsistency between in vivo and in vitro observations might be attributed to systemic circadian control rather than a direct cell-autonomous control.

    The CLIL approach is a modern manner of teaching English, which has been adapted in Romanian schools and universities. An interesting aspect of learning a foreign language is the contact with its culture/s and the changes it produces in terms of identity. Therefore, a challenging question to be answered is whether a CLIL approach focusing on culture influences students' cultural identity.

    Full Text Available Women who inject drugs (WID are highly marginalized and stigmatized and experience ongoing discrimination in Georgia. Few opportunities exist for WID to receive publicly funded treatment for substance use disorders. The IMEDI (Investigating Methods for Enhancing Development in Individuals project was developed in response to the need for women-specific and women-centered treatment services. This paper described our approach to understanding the Georgian culture—and WID within that culture—so that we could integrate two interventions for substance use found effective in other Western and non-Western cultures and to outline how we refined and adapted our integrated intervention to yield a comprehensive women-centered intervention for substance use. Reinforcement Based Treatment (RBT and the Women’s CoOp (WC were adapted and refined based on in-depth interviews with WID (N=55 and providers of health services (N=34 to such women and focus groups [2 with WID (N=15 and 2 with health service providers (N=12]. The resulting comprehensive women-centered intervention, RBT+WC, was then pretested and further refined in a sample of 20 WID. Results indicated positive pre-post changes in urine screening results and perceived needs for both RBT+WC and a case management control condition. The approach to treatment adaptation and the revised elements of RBT+WC are presented and discussed.

    This study compared the three most commonly used assays for detecting Cryptosporidium sp. infections in cell culture: immunofluorescent antibody and microscopy assay (IFA), PCR targeting Cryptosporidium sp.-specific DNA, and reverse transcriptase PCR (RT-PCR) targeting Cryptosporidium sp.-specific mRNA. Monolayers of HCT-8 cells, grown in 8-well chamber slides or 96-well plates, were inoculated with a variety of viable and inactivated oocysts to assess assay performance. All assays detected infection with low doses of flow cytometry-enumerated Cryptosporidium parvum oocysts, including infection with one oocyst and three oocysts. All methods also detected infection with Cryptosporidium hominis. The RT-PCR assay, IFA, and PCR assay detected infection in 23%, 25%, and 51% of monolayers inoculated with three C. parvum oocysts and 10%, 9%, and 16% of monolayers inoculated with one oocyst, respectively. The PCR assay was the most sensitive, but it had the highest frequency of false positives with mock-infected cells and inactivated oocysts. IFA was the only infection detection assay that did not produce false positives with mock-infected monolayers. IFA was also the only assay that detected infections in all experiments with spiked oocysts recovered from Envirochek capsules following filtration of 1,000 liters of treated water. Consequently, cell culture with IFA detection is the most appropriate method for routine and sensitive detection of infectious Cryptosporidium parvum and Cryptosporidium hominis in drinking water.

    Orphans and other vulnerable children (OVC) who grow up in institutional care often show communication and language problems. The caregivers lack training, and there are few language didactics programmes aimed at supporting communication and language development in OVC in institutional care in Tanzania. The purpose of the study was to adapt the German concept of relational communication therapy (RCT) as a support to language development in a Tanzanian early childhood education context in a culturally sensitive way. Following the adaptation of the concept, a training programme for Tanzanian caregiver students was developed to compare their competencies in language didactics before and after training. A convergent mixed methods design was used to examine changes following training in 12 participating caregiver students in a Tanzanian orphanage. The competencies in relational language didactics were assessed by a self-developed test and video recordings before and after intervention. Based on the results, we drew conclusions regarding necessary modifications to the training modules and to the concept of RCT. The relational didactics competencies of the caregiver students improved significantly following their training. A detailed analysis of the four training modules showed that the improvement in relational didactics competencies varied depending on the topic and the teacher. The results provide essential hints for the professionalisation of caregivers and for using the concept of RCT for OVC in institutional care in Tanzania. Training programmes and concepts should not just be transferred across different cultures, disciplines and settings; they must be adapted to the specific cultural setting.

    In Sweden, migrants have poorer sexual and reproductive health compared to the general population. Health literacy, in the form of the cognitive and social skills enabling access to health promoting activities, is often poorer among migrants, partly due to language and cultural barriers. Culturally sensitive health education provides a strategy for enhancing health literacy. Since 2012, specially trained civic and health communicators have provided sexual and reproductive health and rights information to newly arrived refugees in Skåne, Sweden. The aim of this study was to explore how information on sexual and reproductive health and rights was perceived by female recipients and whether being exposed to such information contributed to enhanced sexual and reproductive health and rights literacy. Semi-structured in-depth interviews were conducted with nine women and analysed using qualitative content analysis. Two themes emerged: (1) opening the doors to new understandings of sexual and reproductive health and rights and (2) planting the seed for engagement in sexual and reproductive health and rights issues, illustrating how cultural norms influenced perceptions, but also how information opened up opportunities for challenging these norms. Gender-separate groups may facilitate information uptake, while discussion concerning sexual health norms may benefit from taking place in mixed groups.

    The three dimensional (3D) cell culture in polymer-based micro system has become a useful tool for in vitro drug discovery. Among those polymers, polysulfone hollow fiber membrane (PSf HFM) is commonly used to create a microenvironment for cells. However, the target drug may adsorb on the polymeric surface, and this elicits negative impacts on cell exposure due to the reduced effective drug concentration in culture medium. In order to reduce the drug adsorption, PSf membrane were modified with hydrophilic Pluronic (PEO-b-PPO-b-PEO) copolymers, L121, P123 and F127 (PEO contents increase from 10%, 30% to 70%), by physical adsorption. As a result, the hydrophilicity of HFMs increased at an order of PSfF127>P123>L121 HFMs. The three modified membrane all showed significant resistance to adsorption of acid/neutral drugs. More importantly, the adsorption of base drugs were largely reduced to an average value of 11% on the L121 HFM. The improved resistance to drug adsorption could be attributed to the synergy of hydrophobic/neutrally charged PPO and hydrophilic PEO. The L121 HFM was further assessed by evaluating the drug hepatotoxicity in 3D culture of hepatocytes. The base drugs, clozapine and doxorubicin, showed more sensitive hepatotoxicity on hepatocytes in L121 HFM than in PSf HFM, while the acid drug, salicylic acid, showed the similar hepatotoxicity to hepatocytes in both HFMs. Our finding suggests that PSf HFM modified by PEO-b-PPO-b-PEO copolymers can efficiently resist the drug adsorption onto polymer membrane, and consequently improve the accuracy and sensitivity of in vitro hepatotoxic drug screening.

    The high prevalence of urinary tract infections (UTIs) places a significant burden on healthcare systems. Clinicians may over-manage the issue, and there is great variability in practice, with economic- and resource- implications. Up to 40% of patients with a suspected UTI do not have an infection. Using PubMed (Medline) to shortlist relevant papers in English from the last 30 years, and further sub-selection to include only uncomplicated UTIs in adults in primary care, we reviewed the literature pertaining to uncomplicated UTIs, and how it should be managed efficiently in the primary care setting. In general practice, there is no advantage to routinely request microscopy and culture of urine samples in the presence of an appropriate history and urinalysis reagent-strip testing. If antibiotics are required, then a 3-day course shall suffice. Larger epidemiological studies focusing on more susceptible sub-populations may provide better guidance for discriminatory factors to produce an algorithm for treatment.

    Reductive dechlorination catalyzed by organohalide-respiring bacteria is often considered for remediation of non-aqueous phase liquid (NAPL) source zones due to cost savings, ease of implementation, regulatory acceptance, and sustainability. Despite knowledge of the key dechlorinators, an understanding of the processes and factors that control NAPL dissolution rates and detoxification (i.e., ethene formation) is lacking. A recent column study demonstrated a 5-fold cumulative enhancement in tetrachloroethene (PCE) dissolution and ethene formation (Amos et al., 2009). Spatial and temporal monitoring of key geochemical and microbial (i.e., Geobacter lovleyi and Dehalococcoides mccartyi strains) parameters in the column generated a data set used herein as the basis for refinement and testing of a multiphase, compositional transport model. The refined model is capable of simulating the reactive transport of multiple chemical constituents produced and consumed by organohalide-respiring bacteria and accounts for substrate limitations and competitive inhibition. Parameter estimation techniques were used to optimize the values of sensitive microbial kinetic parameters, including maximum utilization rates, biomass yield coefficients, and endogenous decay rates. Comparison and calibration of model simulations with the experimental data demonstrate that the model is able to accurately reproduce measured effluent concentrations, while delineating trends in dechlorinator growth and reductive dechlorination kinetics along the column. Sensitivity analyses performed on the optimized model parameters indicate that the rates of PCE and cis-1,2-dichloroethene (cis-DCE) transformation and Dehalococcoides growth govern bioenhanced dissolution, as long as electron donor (i.e., hydrogen flux) is not limiting. Dissolution enhancements were shown to be independent of cis-DCE accumulation; however, accumulation of cis-DCE, as well as column length and flow rate (i.e., column residence time

    Broiler chicken flocks are a significant source of Campylobacter jejuni and Campylobacter coli that result in the major public health problem of campylobacteriosis. Accurate estimates of the prevalence of both C. coli and C. jejuni in flocks would enhance epidemiological understanding, risk assessment and control options. This study combined results from a panel of 10 detection tests (direct culture, enrichment and PCR) on caecal samples from flocks at slaughter. A parallel interpretation approach was used to determine the presence of Campylobacter spp. and for C. jejuni and C. coli individually. The sample was considered positive if at least one method detected the target and this interpretation was taken to represent a 'proxy gold standard' for detection in the absence of a gold standard reference test. The sensitivity of each individual method to detect Campylobacter spp., C. jejuni and C. coli was then estimated relative to the proxy gold standard. Enrichment in adapted Exeter broth (deficient in polymyxin B) with a resuscitation step was 100% sensitive, whilst direct culture on modified charcoal cefoperazone deoxycholate agar (mCCDA) was highly sensitive (97.9%). Enrichment methods using Preston broth and Bolton broth were significantly less sensitive. Enrichment in Exeter broth promoted the recovery of C. jejuni, whilst enrichment in Bolton broth favoured C. coli. A RT-PCR detection test could identify 80% of flocks that were co-colonised with both species. This study found that 76.3% (n = 127) of flocks were colonised with Campylobacter spp. The majority (95.9%) of Campylobacter-positive flocks were colonised with C. jejuni; however, approximately one-third of positive flocks were simultaneously colonised with both C. jejuni and C. coli. The findings highlight the impact of different detection methodologies on the accuracy of the estimated incidence of both C. jejuni and C. coli entering the abattoir within broiler flocks and the associated

    Full Text Available The expression and metabolic profile of cytochrome P450s (CYPs is largely missing in human brain due to non-availability of brain tissue. We attempted to address the issue by using human brain neuronal (SH-SY5Y and glial (U373-MG cells. The expression and activity of CYP1A1, 2B6 and 2E1 were carried out in the cells exposed to CYP inducers viz., 3-methylcholanthrene (3-MC, cyclophosphamide (CPA, ethanol and known neurotoxicant- monocrotophos (MCP, a widely used organophosphorous pesticide. Both the cells show significant induction in the expression and CYP-specific activity against classical inducers and MCP. The induction level of CYPs was comparatively lower in MCP exposed cells than cells exposed to classical inducers. Pre-exposure (12 h of cells to classical inducers significantly added the MCP induced CYPs expression and activity. The findings were concurrent with protein ligand docking studies, which show a significant modulatory capacity of MCP by strong interaction with CYP regulators-CAR, PXR and AHR. Similarly, the known CYP inducers- 3-MC, CPA and ethanol have also shown significantly high docking scores with all the three studied CYP regulators. The expression of CYPs in neuronal and glial cells has suggested their possible association with the endogenous physiology of the brain. The findings also suggest the xenobiotic metabolizing capabilities of these cells against MCP, if received a pre-sensitization to trigger the xenobiotic metabolizing machinery. MCP induced CYP-specific activity in neuronal cells could help in explaining its effect on neurotransmission, as these CYPs are known to involve in the synthesis/transport of the neurotransmitters. The induction of CYPs in glial cells is also of significance as these cells are thought to be involved in protecting the neurons from environmental insults and safeguard them from toxicity. The data provide better understanding of the metabolizing capability of the human brain cells against

We attempted to address the issue by using human brain neuronal (SH-SY5Y) and glial (U373-MG) cells. The expression and activity of CYP1A1, 2B6 and 2E1 were carried out in the cells exposed to CYP inducers viz., 3-methylcholanthrene (3-MC), cyclophosphamide (CPA), ethanol and known neurotoxicant- monocrotophos (MCP), a widely used organophosphorous pesticide. Both the cells show significant induction in the expression and CYP-specific activity against classical inducers and MCP. The induction level of CYPs was comparatively lower in MCP exposed cells than cells exposed to classical inducers. Pre-exposure (12 h) of cells to classical inducers significantly added the MCP induced CYPs expression and activity. The findings were concurrent with protein ligand docking studies, which show a significant modulatory capacity of MCP by strong interaction with CYP regulators-CAR, PXR and AHR. Similarly, the known CYP inducers- 3-MC, CPA and ethanol have also shown significantly high docking scores with all the three studied CYP regulators. The expression of CYPs in neuronal and glial cells has suggested their possible association with the endogenous physiology of the brain. The findings also suggest the xenobiotic metabolizing capabilities of these cells against MCP, if received a pre-sensitization to trigger the xenobiotic metabolizing machinery. MCP induced CYP-specific activity in neuronal cells could help in explaining its effect on neurotransmission, as these CYPs are known to involve in the synthesis/transport of the neurotransmitters. The induction of CYPs in glial cells is also of significance as these cells are thought to be involved in protecting the neurons from environmental insults and safeguard them from toxicity. The data provide better understanding of the metabolizing capability of the human brain cells against xenobiotics.

    A sensitive and specific method that also demonstrates viability is of interest for detection of E. coli O157:H7 in drinking water. A combination of culture and qPCR was investigated. Two triplex qPCRs, one from a commercial source and another designed for this study were optimized from 5 different assays to be run on a single qPCR plate. The qPCR assays were specific for 33 E. coli O157:H7 strains tested and detected 500 cells spiked in a background of 10(8) nontarget bacterial cells. The qPCR detection was combined with an enrichment process using Presence Absence (P/A) broth to detect chlorine and starvation stressed cells. qPCR analysis performed post-enrichment allowed the detection of 3-4 cells/L as indicated by a sharp increase in fluorescence (lowering of Ct values) from pre-enrichment levels, demonstrating a 5-6 log increase in the number of cells. When six vulnerable untreated surface water samples were examined, only one was positive for viable E. coli O157:H7 cells. These results suggest that the culture-PCR procedure can be used for rapid detection of E. coli O157:H7 in drinking water.

    Water-based detergent systems offer several advantages, over organic solvents, for the cleaning of cultural heritage artifacts in terms of selectivity and gentle removal of grime materials or aged varnish, which are known to alter the readability of the painting. Unfortunately, easel paintings present specific characteristics that make the usage of water-based systems invasive. The interaction of water with wood or canvas support favors mechanical stresses between the substrate and the paint layers leading to the detachment of the pictorial layer. In order to avoid painting loss and to ensure a fine control (layer by layer) of grime removal, water-based cleaning systems have been confined into innovative chemical hydrogels, specifically designed for cleaning water-sensitive cultural heritage artifacts. The synthesized hydrogels are based on semi-interpenetrating chemical poly(2-hydroxyethyl methacrylate)/poly(vinylpyrrolidone) networks with suitable hydrophilicity, water retention properties, and required mechanical strength to avoid residues after the cleaning treatment. Three different compositions were selected. Water retention and release properties have been studied by quantifying the amount of free and bound water (from differential scanning calorimetry); mesoporosity was obtained from scanning electron microscopy; microstructure from small angle X-ray scattering. To demonstrate both the efficiency and versatility of the selected hydrogels in confining and modulating the properties of cleaning systems, a representative case study is presented.

    The effects of acute and chronic treatment with ethanol were studied on the number and activity of tetrodotoxin-sensitive Na-channels in cultured rat skeletal muscle. The number of channels was determined by measurements of specific binding of (3H) saxitoxin (STX) in whole cell preparations. Measurements were also made of the frequency and rate of rise of spontaneously occurring action potentials, which are the physiologic expression of Na-channel density. Acute ethanol (37.5-150 mM), while causing depolarization of membrane potential and blockade of electrical activity, was without effect on specific STX binding. Neither methanol, acetaldehyde nor ethylene glycol had significant effects on these properties when given acutely in the same concentrations as ethanol. Chronic ethanol caused dose-related increases in STX binding and action potential properties with maximal levels being attained after 3 days of treatment at a concentration of 150 mM. On removal of ethanol from the culture medium all properties returned to control levels after 48 hr. Both increased external K+ and tetrodotoxin, which up-regulate Na-channels by reducing cytosolic Ca++, potentiated the ethanol-induced increase in Na-channel density. The increase in STX binding was not associated with changes in affinity of the binding sites for the ligand but was completely prevented by treatment with cycloheximide and actinomycin D. The results demonstrate that ethanol interacts with the cell membrane to induce synthesis of STX-binding sites.

    Full Text Available Background: Orphans and other vulnerable children (OVC who grow up in institutional care often show communication and language problems. The caregivers lack training, and there are few language didactics programmes aimed at supporting communication and language development in OVC in institutional care in Tanzania.Objectives: The purpose of the study was to adapt the German concept of relational communication therapy (RCT as a support to language development in a Tanzanian early childhood education context in a culturally sensitive way. Following the adaptation of the concept, a training programme for Tanzanian caregiver students was developed to compare their competencies in language didactics before and after training.Methods: A convergent mixed methods design was used to examine changes following training in 12 participating caregiver students in a Tanzanian orphanage. The competencies in relational language didactics were assessed by a self-developed test and video recordings before and after intervention. Based on the results, we drew conclusions regarding necessary modifications to the training modules and to the concept of RCT.Results: The relational didactics competencies of the caregiver students improved significantly following their training. A detailed analysis of the four training modules showed that the improvement in relational didactics competencies varied depending on the topic and the teacher.Conclusion: The results provide essential hints for the professionalisation of caregivers and for using the concept of RCT for OVC in institutional care in Tanzania. Training programmes and concepts should not just be transferred across different cultures, disciplines and settings; they must be adapted to the specific cultural setting.

    Excitotoxic neuronal death has been linked to neurological and neurodegenerative diseases. Several studies have sought to clarify the involvement of Cl(-) channels in neuronal excitotoxicity using either N-methyl-D-aspartic acid (NMDA) or alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate/kainic acid agonists. In this work we induced excitotoxic death in primary cultures of cerebellar granule cells by means of endogenously released glutamate. Excitotoxicity was provoked by exposure to high extracellular K(+) concentrations ([K(+)](o)) for 5 min. Under these conditions, a Ca(2+)-dependent release of glutamate was evoked. When extracellular glutamate concentration rose to between 2 and 4 microM, cell viability was significantly reduced by 30-40%. The NMDA receptor antagonists (MK-801 and D-2-amino-5-phosphonopentanoic acid) prevented cell death. Exposure to high [K(+)](o) produced a (36)Cl(-) influx which was significantly reduced by picrotoxinin. In addition, the GABA(A) receptor antagonists (bicuculline, picrotoxinin and SR 95531) protected cells from high [K(+)](o)-triggered excitotoxicity and reduced extracellular glutamate concentration. The Cl(-) channel blockers niflumic acid and 5-nitro-2-(3-phenylpropylamino)benzoic acid also exerted a neuroprotective effect and reduced extracellular glutamate concentration, even though they did not reduce high [K(+)](o)-induced (36)Cl(-) influx. Primary cultures of cerebellar granule cells also contain a population of GABAergic neurons that released GABA in response to high [K(+)](o). Chronic treatment of primary cultures with kainic acid abolished GABA release and rendered granule cells insensitive to high [K(+)](o) exposure, even though NMDA receptors were functional. Altogether, these results demonstrate that, under conditions of membrane depolarization, low micromolar concentrations of extracellular glutamate might induce an excitotoxic process through both NMDA and GABA(A) receptors and niflumic acid-sensitive Cl

    Many of the approximately 15 million people with a migration background living in Germany (19% of the population) are inadequately reached by existing healthcare provision. In the literature, the necessity for cultural adaptation of information material for patients with a migration background is often cited as a measure for improving healthcare.In this study, culturally sensitive information material will be developed and evaluated for patients with a migration background and depression or chronic low back pain. In this respect, it will be examined whether culturally sensitive information material is judged as more useful by the patients than standard translated patient information without cultural adaptation. The implementation and evaluation of culturally sensitive patient information material will occur in the framework of a double-blind randomized controlled parallel-group study in four study centres in Germany. Primary care patients with a Turkish, Polish, Russian or Italian migration background with a diagnosis of depressive disorder or chronic low back pain will be included and randomly allocated to the intervention group or the control group. In the intervention group, culturally sensitive patient information will be handed to the patient at the end of the physician consultation, while in the control group, standard translated patient information material will be provided. The patients will be surveyed by means of questionnaires following the consultation as well as after 8 weeks and 6 months. In addition to the primary outcome (subjective usefulness), several patient- and physician-rated secondary outcomes will be considered. The study will provide an empirical answer to the question of whether persons with a migration background perceive culturally sensitive patient information material as more useful than translated information material without cultural adaptation.

    The present study aimed to investigate the effect of jueming prescription (JMP) and its ingredients, semen cassiae (SC) and Rhizoma Curcumae Longae (RCL), on lipolysis, and to examine their effect on the phosphorylation of hormone‑sensitive lipase (HSL) in cultured rat white adipose tissue (WAT). Retroperitoneal WAT was aseptically excised from adult male Sprague‑Dawley rats, minced into uniform sections and subjected to ex vivo culture for 24 h. The tissue sections were then distributed into a 24‑well culture plate and treated with normal saline (vehicle), isoproterenol (ISO), JMP, SC and RCL. Non‑esterified fatty acid (NEFA) and glycerol release from the intact WAT explants were determined as a measurement of lipolysis, which were measured using NEFA and glycerol assay kits. The phosphorylation of HSL at Ser563 (P‑HSL S563) and 660 residues (P‑HSL S660) were determined using western blot analysis. The size of the adipocytes was visualized using hematoxylin and eosin (H&E) staining. It was found that JMP‑, SC‑ and RCL‑stimulated lipolysis was responsible for increasing the release of NEFAs and glycerol from the intact WAT in vitro. In addition, JMP, SC and RCL increased the levels of P‑HSL Ser563: JMP water (JW) extract, 3.52‑fold; JMP ethanol (JE) extract, 3.38‑fold; SC water (SW) extract, 4.60‑fold; SC ethanol (SE) extract, 4.20‑fold; RCL water (RW) extract, 6.98‑fold; RCL ethanol (RE) extract, 6.60‑fold. JMP, SC and RCL also increased the levels of P‑HSL Ser660: JW extract, 3.16‑fold; JE extract, 2.92‑fold; SW extract, 4.57‑fold; SE extract, 4.13‑fold; RW extract, 5.41‑fold; RE 4.96‑fold) in the WAT. The RW extract had the most marked effect. The HE staining revealed that JMP, SC and RCL reduced the size of adipocytes in the WAT. In conclusion, JMP and its ingredients, SC and RC, stimulated lipolysis and reduced the size of adipocytes, possibly via the phosphorylation of HSL in cultured rat WAT.

    2012-03-01

    Full Text Available Abstract Background Compared to those in higher socioeconomic groups, diabetic patients in lower socioeconomic groups have less favourable metabolic control and experience more diabetes-related complications. They encounter specific barriers that hinder optimal diabetes self-management, including a lack of social support and other psychosocial mechanisms in their immediate social environments. Powerful Together with Diabetes is a culturally sensitive social network intervention specifically targeted to ethnic Dutch, Moroccan, Turkish, and Surinamese diabetic patients in lower socioeconomic groups. For ten months, patients will participate in peer support groups in which they will share experiences, support each other in maintaining healthy lifestyles, and learn skills to resist social pressure. At the same time, their significant others will also receive an intervention, aimed at maximizing support for and minimizing the negative social influences on diabetes self-management. This study aims to test the effectiveness of Powerful Together with Diabetes. Methods/Design We will use a quasi-experimental design with an intervention group (Group 1 and two comparison groups (Groups 2 and 3, N = 128 in each group. Group 1 will receive Powerful Together with Diabetes. Group 2 will receive Know your Sugar, a six-week group intervention that does not focus on the participants' social environments. Group 3 receives standard care only. Participants in Groups 1 and 2 will be interviewed and physically examined at baseline, 3, 10, and 16 months. We will compare their haemoglobin A1C levels with the haemoglobin A1C levels of Group 3. Main outcome measures are haemoglobin A1C, diabetes-related quality of life, diabetes self-management, health-related, and intermediate outcome measures. We will conduct a process evaluation and a qualitative study to gain more insights into the intervention fidelity, feasibility, and changes in the psychosocial mechanism in the

    The purpose of the study is to validate a culturally sensitive adaptation of the community-oriented program for the control of rheumatic diseases (COPCORD) methodology in several Latin American indigenous populations. The COPCORD Spanish questionnaire was translated and back-translated into seven indigenous languages: Warao, Kariña and Chaima (Venezuela), Mixteco, Maya-Yucateco and Raramuri (Mexico) and Qom (Argentina). The questionnaire was administered to almost 100 subjects in each community with the assistance of bilingual translators. Individuals with pain, stiffness or swelling in any part of the body in the previous 7 days and/or at any point in life were evaluated by physicians to confirm a diagnosis according to criteria for rheumatic diseases. Overall, individuals did not understand the use of a 0-10 visual analog scale for pain intensity and severity grading and preferred a Likert scale comprising four items for pain intensity (no pain, minimal pain, strong pain, and intense pain). They were unable to discriminate between pain intensity and pain severity, so only pain intensity was included. For validation, 702 subjects (286 male, 416 female, mean age 42.7 ± 18.3 years) were interviewed in their own language. In the last 7 days, 198 (28.2 %) subjects reported having musculoskeletal pain, and 90 (45.4 %) of these had intense pain. Compared with the physician-confirmed diagnosis, the COPCORD questionnaire had 73.8 % sensitivity, 72.9 % specificity, a positive likelihood ratio of 2.7 and area under the receiver operating characteristic curve of 0.73. The COPCORD questionnaire is a valid screening tool for rheumatic diseases in indigenous Latin American populations.

    Full Text Available Abstract Background This paper describes the process used to develop an integrated set of culturally sensitive, evidence-based counselling tools (job aids by using qualitative participatory research. The aim of the intervention was to contribute to improving infant feeding counselling services for HIV positive women in the Kilimanjaro Region of Tanzania. Methods Formative research using a combination of qualitative methods preceded the development of the intervention and mapped existing practices, perceptions and attitudes towards HIV and infant feeding (HIV/IF among mothers, counsellors and community members. Intervention Mapping (IM protocol guided the development of the overall intervention strategy. Theories of behaviour change, a review of the international HIV/IF guidelines and formative research findings contributed to the definition of performance and learning objectives. Key communication messages and colourful graphic illustrations related to infant feeding in the context of HIV were then developed and/or adapted from existing generic materials. Draft materials were field tested with intended audiences and subjected to stakeholder technical review. Results An integrated set of infant feeding counselling tools, referred to as 'job aids', was developed and included brochures on feeding methods that were found to be socially and culturally acceptable, a Question and Answer Guide for counsellors, a counselling card on the risk of transmission of HIV, and an infant feeding toolbox for demonstration. Each brochure describes the steps to ensure safer infant feeding using simple language and images based on local ideas and resources. The brochures are meant to serve as both a reference material during infant feeding counselling in the ongoing prevention of mother to child transmission (pMTCT of HIV programme and as take home material for the mother. Conclusion The study underscores the importance of formative research and a systematic theory

    A nested PCR method was developed and its performance evaluated by detection of Shigella flexneri in food. The nested PCR amplifies sequences within an invasion-associated locus (ial) on the invasion plasmid specific for Shigella and enteroinvasive Eschrichia coli (EIEC). The nested PCR detected Sh. flexneri in lettuce inoculated with 2, 20 and 200 cfu g-1 after 1, 7 and 18 d of storage, respectively. In comparison, a culture method (NMKL no. 151) detected 10(5) cfu g-1 after 1 but not after 7 d of storage. The presence of inhibitors in blue cheese and shrimps reduced the sensitivity of the PCR assay. To overcome this inhibition, a sample preparation step based on buoyant density centrifugation was developed. This treatment resulted in a successful recovery of Sh. flexneri in lettuce, milk, shrimp and blue cheese inoculated with 10 cfu g-1. The proposed method, which includes a combination of enrichment, buoyant density centrifugation and a nested PCR, can be completed in less than two working days.

    With the further integration of global economy, business competition becomes increasingly fierce;interactions among na⁃tions are more often than before. Business manners become quite necessary because manners convey a man of his or her qualities, self-confidence and spirits. A man’s behaviors in formal occasions are not only for himself but represent his unit, sometimes a na⁃tion’s reputation. Thus in orders to have a successful business negotiation, business behaviors and manners must be watched.This essay is aim at speech and gifting manners in foreign business:One is that we need attention on wordage, appellations and topics in talking. The other is that we shall mind pick, gifting and acceptance of presents.

    The quantitative detection of viable pathogen load is an important tool in determining the degree of infection in animals and contamination of foodstuffs. Current conventional culture methods are limited in their ability to determine these levels in Mycobacterium avium subspecies paratuberculosis (MAP) due to slow growth, clumping and low recoverability issues. The principle goal of this study was to evaluate a novel culturing process (TiKa) with unique ability to stimulate MAP growth from low sample loads and dilutions. We demonstrate it was able to stimulate a mean 29-fold increase in recoverability and an improved sensitivity of up to three logs when compared with conventional culture. Using TiKa culture, MAP clumping was minimal and produced visible colonies in half the time required by standard culture methods. Parallel quantitative evaluation of the TiKa culture approach and qPCR on MAP loads in tissue and gut mucosal samples from a MAP vaccine-challenge study, showed good correlations between colony counts (cfu) and qPCR derived genome equivalents (Geq) over a large range of loads with a 30% greater sensitivity for TiKa culture approach at low loads (two logs). Furthermore, the relative fold changes in Geq and cfu from the TiKa culture approach suggests that non-mucosal tissue loads from MAP infected animals contained a reduced proportion of non-viable MAP (mean 19-fold) which was reduced significantly further (mean 190-fold) in vaccinated "reactor" calves. This study shows TiKa culture equates well with qPCR and provides important evidence that accuracy in estimating viable MAP load using DNA tests alone may vary significantly between samples of mucosal and lymphatic origin.

  7. Mind your "smoking manners": the tobacco industry tactics to normalize smoking in Japan.

    2013-11-09

    The tobacco industry has adapted its promotional strategies as tobacco-control measures have increased. This paper describes the tobacco industry's strategies on smoking manners and illustrates how these interfere with tobacco-control policy in Japan where tobacco control remains weak. Information on the tobacco industry's promotional strategies in Japan was collected through direct observation, a review of tobacco industry documents and a literature review. The limitation of the study would be a lack of industry documents from Japan as we relied on a database of a U.S. institution to collect internal documents from the tobacco industry. Japan Tobacco began using the manners strategies in the early 1960s. Collaborating with wide range of actors -including local governments and companies- the tobacco industry has promoted smoking manners to wider audiences through its advertising and corporate social responsibility activities. The tobacco industry in Japan has taken advantage of the cultural value placed on manners in Japan to increase the social acceptability of smoking, eventually aiming to diminish public support for smoke-free policies that threatens the industry's business. A stronger enforcement of the WHO Framework Convention on Tobacco Control is critical to counteracting such strategies.

    An increase in Src activity is commonly observed in epithelial cancers. Aberrant activation of the kinase activity is associated with malignant progression. However, the mechanisms that underlie the Src-induced malignant progression of cancer are not completely understood. We show here that v-Src, an oncogene that was first identified from a Rous sarcoma virus and a mutant variant of c-Src, leads to an increase in the number of anaphase and telophase cells having chromosome bridges. v-Src increases the number of γH2AX foci, and this increase is inhibited by treatment with PP2, a Src kinase inhibitor. v-Src induces the phosphorylation of KAP1 at Ser824, Chk2 at Thr68, and Chk1 at Ser345, suggesting the activation of the ATM/ATR pathway. Caffeine decreases the number of cells having chromosome bridges at a concentration incapable of inhibiting Chk1 phosphorylation at Ser345. These results suggest that v-Src induces chromosome bridges via generation of DNA damage and the subsequent DNA damage response, possibly by homologous recombination. A chromosome bridge gives rise to the accumulation of DNA damage directly through chromosome breakage and indirectly through cytokinesis failure-induced multinucleation. We propose that v-Src-induced chromosome bridge formation is one of the causes of the v-Src-induced malignant progression of cancer cells.

    Full Text Available Background: Research shows that trauma-focused therapy and multimodal interventions are the two most often used strategies in treatment of refugees suffering from posttraumatic stress disorder (PTSD. While preliminary evidence suggests that trauma-focused approaches may have some efficacy, this could not be established for multimodal interventions. However, it may be that multimodal interventions have been studied in more treatment-resistant refugees with very high levels of psychopathology, disability, and chronicity. In the past decades, various models for understanding of the complex relationship between mental health problems and well-being have emerged. They aim at framing mental health problems in individualized, contextual, epigenetic, and culturally sensitive ways, and may be useful in tailoring content and timing of multimodal interventions. Objective: To draw clinicians’ attention to the possibility of using the Integrative Contextual Model for understanding and assessment of posttrauma mental health sequelae while tailoring multimodal interventions; to present a possible way of combining multimodal with evidence-based trauma-focused approaches; and to improve the understanding and treatment of PTSD and other mental health problems in refugee survivors of prolonged and repeated trauma. Method: Based on literature, clinical experience, and presentation of a fictional case, the use of the Integrative Contextual Model in tailoring the treatment of severe PTSD in a refugee patient is presented and discussed. Results: The Integrative Contextual Model for understanding and assessing factors, which may play a role in causing and maintaining of PTSD and comorbidity in refugees, may help tailoring of multimodal interventions. These interventions can be combined with evidence-based trauma-focused treatments. Conclusion: The field of refugee mental health intervention and clinical practice with traumatized refugees may be enriched with the use

    Since 2010, studies on the diagnostic accuracy of COBAS TaqMan MTB (CTM) have been frequently reported with an unignorable discrepancy. The key inclusion criterion for this systematic review was original studies that could provide sufficient data for calculating the sensitivity and the specificity of CTM for M tuberculosis (TB) or M tuberculosis complex. The reference test was Mycobacterium culture. We used bivariate model for meta-analyses. Of the 201 candidate articles, we finally identified 17 eligible articles.Concerning the respiratory specimens, 1900 culture positive specimens and 20983 culture negative specimens from 15 studies were assessed. This provided the summary estimate sensitivity of 0.808 (95% CI 0.758-0.850) and the summary estimate specificity of 0.990 (95% CI 0.981-0.994). The area under curve was 0.956. The diagnostic odds ratio was 459 (95% CI 261-805, I(2) 26%). For the smear positive respiratory specimens, the sensitivity was 0.952 (95% CI 0.926-0.969) and the specificity was 0.916 (95% CI 0.797-0.968). For the smear negative respiratory specimens, the sensitivity and the specificity were 0.600 (95% CI 0.459-0.726) and 0.989 (95% CI 0.981-0.993), respectively. The diagnostic accuracy was poorer for the non-respiratory specimens, than for the respiratory specimens, but was acceptable. We believe that the information obtained from this study will aid physicians' decision making.

    The nuclear accumulation of beta-catenin plays an important role in the Wingless/Wnt signaling pathway. This study describes an examination of the nuclear import of beta-catenin in living mammalian cells and in vitro semi-intact cells. When injected into the cell cytoplasm, beta-catenin rapidly migrated into the nucleus in a temperature-dependent and wheat germ agglutinin-sensitive manner. In the cell-free import assay, beta-catenin rapidly migrates into the nucleus without the exogenous addition of cytosol, Ran, or ATP/GTP. Cytoplasmic injection of mutant Ran defective in its GTP hydrolysis did not prevent beta-catenin import. Studies using tsBN2, a temperature-sensitive mutant cell line that possesses a point mutation in the RCC1 gene, showed that the import of beta-catenin is insensitive to nuclear Ran-GTP depletion. These results show that beta-catenin possesses the ability to constitutively translocate through the nuclear pores in a manner similar to importin beta in a Ran-unassisted manner. We further showed that beta-catenin also rapidly exits the nucleus in homokaryons, suggesting that the regulation of nuclear levels of beta-catenin involves both nuclear import and export of this molecule.

    As the carrier of culture,language is considered as the main expressional form of culture which develops with nation,country and society’s development.Language is a part of a nation’s culture.The different nations own their unique cultures,his-tory,manners and customs and so on.However,various cultural characteristics can be displayed in the form of language.This ar-ticle,by analyzing the influence and the difference of historical culture,regional culture and custom culture,mainly reveals the relationship between language and culture which is interdependent and interactive.What’s more,a better comprehension of this relationship prevents us from misunderstanding in cross-culture communication.

  13. Sensitive innovation

    DEFF Research Database (Denmark)

    Søndergaard, Katia Dupret

    Present paper discusses sources of innovation as heterogenic and at times intangible processes. Arguing for heterogeneity and intangibility as sources of innovation originates from a theoretical reading in STS and ANT studies (e.g. Callon 1986, Latour 1996, Mol 2002, Pols 2005) and from field work...... in the area of mental health (Dupret Søndergaard 2009, 2010). The concept of sensitive innovation is developed to capture and conceptualise exactly those heterogenic and intangible processes. Sensitive innovation is therefore primarily a way to understand innovative sources that can be......, but are not necessarily, recognized and acknowledged as such in the outer organisational culture or by management. The added value that qualifies these processes to be defined as “innovative” are thus argued for along different lines than in more traditional innovation studies (e.g. studies that build on the classic...

    Real-time PCR analysis of milk samples is a fast method to identify intramammary infections (IMI) in dairy cows, and has the potential to be used for routine analysis of test milking composite milk samples. However, the results of the PCR analysis can be difficult to interpret. The objective of this study was to compare the sensitivity (Se) and specificity (Sp) of PCR analysis of composite milk samples, and conventional bacteriological culturing (BC) of quarter milk samples, when used to identify cows with IMI. The comparisons were performed for IMI with four common udder pathogens; Staphylococcus aureus (S aureus), Streptococcus dysgalactiae (Str dysgalactiae), Str uberis and coagulase negative staphylococci (CoNS). The Se and Sp of real-time PCR (SePCR; SpPCR) and BC (SeBC; SpBC) was simultaneously estimated using latent class analysis (LCA), studying one pathogen at the time. Milk samples from 970 dairy cows from 25 herds were included. Aseptically collected quarter milk samples taken at the day before test milking (TM), at the day of TM, and at the day after TM, were analyzed using BC. Non-aseptically collected composite milk samples taken at the day of TM were analyzed using PCR. Moreover, the composite milk somatic cell count (SCC) was recorded and summarized by diagnostic test and bacterial finding. LCA was first performed using only test results from samples taken at the day of TM, but in a second analysis BC results from the three consecutive samplings, interpreted in parallel, were included. The SePCR was significantly higher than the SeBC for S aureus, Str dysgalactiae and CoNS in the first analysis, but only for CoNS in the second analysis. The SpPCR was significantly lower than the SpBC for Str dysgalactiae and CoNS. In conclusion, using PCR analysis of composite milk samples, as a diagnostic tool for identifying cows with IMI increased the Se for all the pathogens investigated (although not always significantly), while Sp in general remained on a

    Full Text Available Abstract Background Live kidney transplantation (LKT is underutilized, particularly among ethnic/racial minorities. The effectiveness of culturally sensitive educational and behavioral interventions to encourage patients' early, shared (with family and health care providers and informed consideration of LKT and ameliorate disparities in consideration of LKT is unknown. Methods/Design We report the protocol of the Talking About Live Kidney Donation (TALK Study, a two-phase study utilizing qualitative and quantitative research methods to design and test culturally sensitive interventions to improve patients' shared and informed consideration of LKT. Study Phase 1 involved the evidence-based development of culturally sensitive written and audiovisual educational materials as well as a social worker intervention to encourage patients' engagement in shared and informed consideration of LKT. In Study Phase 2, we are currently conducting a randomized controlled trial in which participants with progressing chronic kidney disease receive: 1 usual care by their nephrologists, 2 usual care plus the educational materials, or 3 usual care plus the educational materials and the social worker intervention. The primary outcome of the randomized controlled trial will include patients' self-reported rates of consideration of LKT (including family discussions of LKT, patient-physician discussions of LKT, and identification of an LKT donor. We will also assess differences in rates of consideration of LKT among African Americans and non-African Americans. Discussion The TALK Study rigorously developed and is currently testing the effectiveness of culturally sensitive interventions to improve patients' and families' consideration of LKT. Results from TALK will provide needed evidence on ways to enhance consideration of this optimal treatment for patients with end stage renal disease.

    Full Text Available Constantin-Dan Bordeianu1, Cristina-Eugenia Ticu21Department of Ophthalmology, Emergency Hospital, Ploiesti, Romania; 2Provisional Candidate for PhD, Edmonton, AB, CanadaPurpose: To evaluate to what extent contemporary glaucoma abstracts offer complete information and to suggest a new manner of pressure results reporting.Materials, methods, and results: Most of the 36 relevant surgical glaucoma abstracts found in one issue of International Glaucoma Review contain insufficient data-supported statements. Such abstracts cannot offer a clear picture of the study essence if economic, linguistic, or political barriers prevent access to the full text. In order to enrich abstract content and to avoid typographic space waste, a formula is suggested to provide, in one single line of symbols and figures, all the necessary data for statistical interpretation at two evolution moments: the first significative control (6 months and the final one.Conclusion: The current manner of results reporting in surgical glaucoma abstracts is subject to too little standardization, allowing insufficiently data-supported statements. Abstracts, especially those printed in small-circulation language journals, should be conceived and standardized in such a manner that any abstract review reader is capable of grasping the essence of the study at first glance. The suggested manner of reporting results would bring satisfaction to all areas of the process. Publishers would save typographic space, readers would find all the necessary data for statistical analysis and comparison with other studies, and authors would be convinced that the essence of their work would penetrate in spite of any economic, linguistic, or political barriers.Keywords: glaucoma, reporting results, IOP, abstract construction, standardization formula

  4. Hantavirus infection suppresses thrombospondin-1 expression in cultured endothelial cells in a strain-specific manner

    Directory of Open Access Journals (Sweden)

    Svetlana F Khaiboullina

    2016-07-01

    Full Text Available Hantavirus infection is associated with two frequently fatal diseases in humans: hemorrhagic fever with renal syndrome (HFRS and hantavirus pulmonary syndrome (HPS. The pathogenesis of hantavirus infection is complex and not fully understood; however, it is believed to involve virus-induced hyperinflammatory immune responses. Thrombospondin-1 (THBS1 is a large homotrimeric protein that plays a putative role in regulating blood homeostasis. Hyperresponsiveness to inflammatory stimuli has also been associated with defects in the THBS1 gene. Our data suggest that hantavirus infection of human umbilical cord vein endothelial cells (HUVEC suppress the accumulation of THBS1 in the extracellular matrix. Additionally, this suppression is dependent on virus replication, implying a direct mechanism of action. Our data also imply that the pathogenic Andes and Hantaan strains inhibit THBS1 expression while the non-pathogenic Prospect Hill strain showed little inhibition. These observations suggest that a dysregulation of THBS1 may contribute to the pathogenesis of hantavirus infection.

    Previous work suggested that Rothia dentocariosa is associated with periodontal inflammatory disease. However, little is known about the pathogenicity of this bacterium. To characterize host response to this bacterium, we measured (via ELISA) the amount of TNF-α in the culture supernatant following the stimulation of THP-1 cells (a human acute monocytic leukemia cell line) with R. dentocariosa cells (ATCC14189 and ATCC14190). Exposure to bacterial cells induced the production of TNF-α in a dose-dependent manner. The bacterial induction of TNF-α in THP-1 cells was mediated by the Toll-like receptor 2 (TLR2), as demonstrated by gene-specific knockdown via siRNA, which successfully suppressed TLR2 expression and significantly inhibited the production of TNF-α in the culture supernatant. To confirm the role of TLR2, we examined TLR2-dependent NF-κB activation by R. dentocariosa cells in a distinct cell line. Specifically, HEK293 cells were transiently cotransfected with the human TLR2 gene and an NF-κB-dependent luciferase-encoding reporter gene. The bacterial cells induced NF-κB activation in the transfected HEK293 cells in a dose-dependent manner. In contrast, bacterial cells failed to induce NF-κB activation in cells transfected with pEF6 control vector. Taken together, these results suggest that R. dentocariosa induces host TNF-α production by a TLR2-dependent mechanism.

    Glioblastomas (GBL) are the most common and aggressive brain tumors. They are distinguished by high resistance to radiation and chemotherapy. To find novel approaches for GBL classification, we obtained 16 primary GBL cell cultures and tested them with real-time PCR for mRNA expression of several genes (YB-1, MGMT, MELK, MVP, MDR1, BCRP) involved in controlling cell proliferation and drug resistance. The primary GBL cultures differed in terms of proliferation rate, wherein a group of GBL cell cultures with low proliferation rate demonstrated higher resistance to temozolomide. We found that GBL primary cell cultures characterized by high proliferation rate and lower resistance to temozolomide expressed higher mRNA level of the YB-1 and MDR1 genes, whereas upregulated expression of MVP/LRP mRNA was a marker in the group of GBL with low proliferation rate and high resistance. A moderate correlation between expression of YB-1 and MELK as well as YB-1 and MDR1 was found. In the case of YB-1 and MGMT expression, no correlation was found. A significant negative correlation was revealed between mRNA expression of MVP/LRP and MELK, MDR1, and BCRP. No correlation in expression of YB-1 and MVP/LRP genes was observed. It seems that mRNA expression of YB-1 and MVP/LRP may serve as a marker for GBL cell cultures belonging to distinct groups, each of which is characterized by a unique pattern of gene activity.

    2015-09-01

    Chironomids from the genus Chironomus are widely used in laboratory ecotoxicology, but are prone to inbreeding depression, which can compromise test results. The standard Chironomus test species (C. riparius, C. dilutus and C. yoshimatsui) are also not cosmopolitan, making it difficult to compare results between geographic regions. In contrast, the chironomid Paratanytarsus grimmii is cosmopolitan, and not susceptible to inbreeding depression because it reproduces asexually by apomictic parthenogenesis. However, there is no standardised culturing methodology for P. grimmii, and a lack of acute toxicity data for common pollutants (metals and pesticides). In this study, we developed a reliable culturing methodology for P. grimmii. We also determined 24-h first instar LC50s for the metals Cu, Pb, Zn, Cd and the insecticide imidacloprid. By developing this culturing methodology and generating the first acute metal and imidacloprid LC50s for P. grimmii, we provide a basis for using P. grimmii in routine ecotoxicological testing.

    This pilot study purports to address the need for culturally validated, evidence-based assessments and to serve as a springboard for future culturally sensitive research. This study was conducted in the Dominican Republic. It entailed counterbalanced administration of a standard Spanish translation of the Culture-Fair Assessment of Neurocognitive Abilities (S-S CANA) and the standard Spanish translation of the Mini-Mental State Examination (Examen Cognoscitivo Mini-Mental; ECM-M). The sample was composed of 30 Spanish-speaking Dominican adults who met the inclusion criteria for the normative and clinical groups. In an effort to initiate the validation process for the S-S CANA, as well as norm it to the given population, the efficacy of the S-S CANA in determining neuropathology was then compared to that of the ECM-M. Analyses of variance and covariance and t-tests were conducted, and a receiver-operating characteristic curve was computed. Results indicated significantly greater sensitivity and specificity of the S-S CANA relative to the ECM-M.

    2012-07-01

    Full Text Available Through a textual scrutiny of Mary Sheil’s Glimpses of Life and Manners in Persia, this paper aims to examine the ways she represents the Persian women in her travel narrative.  Nineteenth century, as the high noon of British imperialism, saw the emergence of a huge corpus of colonial travel literature on Persia purported to be eye-witness accounts of the journeys made by their writers. Likewise, Mary Sheil claims that her narrative is an innocent transcription of the life and manners in Persia. However, a close analysis of her text reveals that the representations of women are informed by circulating discourses of the time in keeping with British imperialist ideologies. Further, it exposes the power structure embedded in Sheil’s scripting of Persian women. Far from being a monolithic picture, the text presents an ambivalent tableau of Persian women as objects of both derision and admiration. For its analytical framework, this study follows three successive readings focusing on the representation of the Persian women. The interpretation of the passages is guided by theories from Edward Said and Homi K. Bhabha among others.

  12. EFFECTS OF ENTRAINED AIR MANNER ON CAVITATION DAMAGE*

    2011-01-01

    Early in 1953 the experiments by Peterka proved that air entrainment has effects on decreasing cavitation damage. This technology has been widely used in the release works of high dams since the inception of air entrainment in the Grand Goulee Dam in 1960. Behavior, mechanism and application of air entrainment for cavitation damage control have been investigated for over half century. However, severe cavitation damage happened due to complex mechanism of air entrainment. The effects of air entrainment are related to many factors, including geometric parameters, hydraulic parameters and entrained air manners. In the present work an experimental set-up for air entrainment was specially designed, the behavior of reducing cavitation damage was experimentally investigated in the three aspects of entrained air pressure, air tube aera and air tube number. The results show that magnitude of reduction of cavitation damage is closely related to the entrained air tube number as well as entrained air pressure, air tube aera, and that the effect through three air tubes is larger than that through single air tube although the entrained air tubes have the same sum of tube aera, that is, 1 + 1 + 1 > 3. Therefore, it is important to design an effective manner of air entrainment.

    Objective To determine the incidence of pulmonary tuberculosis (TB) in inmates, factors associated with TB, and the time to sputum smear and culture conversion during TB treatment. Methods Prospective cohort study. All prisoners with respiratory symptoms (RS) of any duration were evaluated. After participants signed consent forms, we collected three spontaneous sputum samples on consecutive days. We performed auramine-rhodamine staining, culturing with the thin-layer agar method, Löwestein-Jensen medium and MGIT, susceptibility testing for first-line drugs; and HIV testing. TB cases were followed, and the times to smear and culture conversion to negative were evaluated. Results Of 9,507 prisoners held in four prisons between April/30/2010 and April/30/2012, among them 4,463 were screened, 1,305 were evaluated for TB because of the lower RS of any duration, and 72 were diagnosed with TB. The annual incidence was 505 cases/100,000 prisoners. Among TB cases, the median age was 30 years, 25% had <15 days of cough, 12.5% had a history of prior TB, and 40.3% had prior contact with a TB case. TB-HIV coinfection was diagnosed in three cases. History of prior TB, contact with a TB case, and being underweight were risk factors associated with TB. Overweight was a protective factor. Almost a quarter of TB cases were detected only by culture; three cases were isoniazid resistant, and two resistant to streptomycin. The median times to culture conversion was 59 days, and smear conversion was 33. Conclusions The TB incidence in prisons is 20 times higher than in the general Colombian population. TB should be considered in inmates with lower RS of any duration. Our data demonstrate that patients receiving adequate anti-TB treatment remain infectious for prolonged periods. These findings suggest that current recommendations regarding isolation of prisoners with TB should be reconsidered, and suggest the need for mycobacterial cultures during follow-up. PMID:24278293

    Child and adolescent mental health services in Europe are confronted with children with increasingly diverse socio-cultural backgrounds. Clinicians encounter cultural environments of hyperdiversity in terms of languages and countries of origin, growing diversity within groups, and accelerated change with regards to social and administrational situations (Hannah, in: DelVecchio Good et al. (eds) Shattering culture: American medicine responds to cultural diversity, Russel Sage Foundation, New York, 2011). Children and families who live in these complex constellations face multiple vulnerabilizing factors related to overlapping or intersecting social identities (Crenshaw in Univ Chic Leg Forum 140:139-167, 1989). Mobilizing existing resources in terms of social and family support, and encouraging creative strategies of interculturation in therapeutic work (Denoux, in: Blomart and Krewer (eds) Perspectives de l'interculturel, L'Harmattan, Paris, 1994) may be helpful in order to enhance resilience. Drawing from experiences in the context of French transcultural and intercultural psychiatry, and inspired by the Mc Gill Cultural Consultation in Child Psychiatry, we developed an innovative model, the Intercultural Consultation Service (ICS). This consultation proposes short term interventions to children and families with complex migration experiences. It has been implemented into a local public health care structure in Toulouse, the Medical and Psychological Centre la Grave. The innovation includes the creation of a specific setting for short term therapeutic interventions and team training via shared case discussions. Our objectives are (a) to improve outcomes of mental health care for the children through a better understanding of the child's family context (exploration of family dynamics and their relatedness to complex migration histories), (b) to enhance intercultural competencies in professionals via shared case discussions, and, (c) to improve the therapeutic

    Two studies tested the conditions under which an environment (e.g., library, restaurant) raises the relevance of environment-specific social norms (e.g., being quiet, using table manners). As hypothesized, the relevance of such norms is raised when environments are goal relevant ("I am going there later") and when they are humanized with people or the remnants of their presence (e.g., a glass of wine on a table). Two studies show that goal-relevant environments and humanized environments raise the perceived importance of norms (Study 1) and the intention to conform to norms (Study 2). Interestingly, in both studies, these effects reach beyond norms related to the environments used in the studies.

    Full Text Available Abstract Background Calcium (Ca2+ has recently been shown to selectively increase the activity of monoamine oxidase-A (MAO-A, a mitochondria-bound enzyme that generates peroxyradicals as a natural by-product of the deamination of neurotransmitters such as serotonin. It has also been suggested that increased intracellular free Ca2+ levels as well as MAO-A may be contributing to the oxidative stress associated with Alzheimer disease (AD. Results Incubation with Ca2+ selectively increases MAO-A enzymatic activity in protein extracts from mouse hippocampal HT-22 cell cultures. Treatment of HT-22 cultures with the Ca2+ ionophore A23187 also increases MAO-A activity, whereas overexpression of calbindin-D28K (CB-28K, a Ca2+-binding protein in brain that is greatly reduced in AD, decreases MAO-A activity. The effects of A23187 and CB-28K are both independent of any change in MAO-A protein or gene expression. The toxicity (via production of peroxyradicals and/or chromatin condensation associated with either A23187 or the AD-related β-amyloid peptide, which also increases free intracellular Ca2+, is attenuated by MAO-A inhibition in HT-22 cells as well as in primary hippocampal cultures. Conclusion These data suggest that increases in intracellular Ca2+ availability could contribute to a MAO-A-mediated mechanism with a role in AD-related oxidative stress.

    Full Text Available The aim of the study was to determine the influence of different concentrations of phytoestrogens biochanin A (BIO A; 20, 40, 50μg ml-1 and daidzein (DAI; 10, 20, 40, 50μg ml-1 on the course of meiotic maturation of pig oocytes. After a 24-hour cultivation, a stage of nuclear maturation was achieved and the areas of cumulus-oocyte complexes (COCs, as an indicator of cumulus expansion, were evaluated. The effects of both contaminants on oocytes were mani - fested from the lowest concentration used. Nuclear maturation was inhibited in a dose-dependent manner in the case of BIO A. Effects of DAI reached a plateau at a concentration of 20μg ml-1.Possible relationship to limited solubility of DAI was excluded because limits of DAI solubility in culture medium were confirmed at 50 μg ml-1.The cumulus expansion was also influenced in a different manner - reduction of the COC’s area by BIO A was dose-dependent, whereas DAI had the strongest effect on CCs in the lowest and highest concentrations used. Both phytoestrogens negatively influence the meiotic maturation of porcine oocytes but there are significant differences in their concrete effects which could relate to the diverse mechanisms of their acting on target cells.

    Full Text Available GABA is the major inhibitory neurotransmitter in the adult brain and mechanisms of GABAergic inhibition have been intensely investigated in the past decades. Recent studies provided evidence for an important role of astrocytes in shaping GABAergic currents. One of the most obvious, but yet poorly understood, mechanisms of the cross-talk between GABAergic currents and astrocytes is metabolism including neurotransmitter homeostasis. In particular, how modulation of GABAergic currents by astrocytes depends on key enzymes involved in cellular metabolism remains largely unknown. To address this issue, we have considered two simple models of neuronal cultures: nominally astrocyte-free neuronal culture (NC and neuronal-astrocytic co-cultures (ANCC and miniature Inhibitory Postsynaptic Currents (mIPSCs were recorded in control conditions and in the presence of respective enzyme blockers. We report that enrichment of neuronal culture with astrocytes results in a marked increase in mIPSC frequency. This enhancement of GABAergic activity was accompanied by increased number of GAD65 and vGAT puncta, indicating that at least a part of the frequency enhancement was due to increased number of synaptic contacts. Inhibition of glutamine synthetase (with MSO strongly reduced mIPSC frequency in ANCC but had no effect in NC. Moreover, treatment of ANCC with inhibitor of glycogen phosphorylase (BAYU6751 or with selective inhibitor of astrocytic Krebs cycle,fluoroacetate, resulted in a marked reduction of mIPSC frequency in ANCC having no effect in NC. We conclude that GABAergic synaptic transmission strongly depends on neuron-astrocyte interaction in a manner dependent on key metabolic enzymes as well as on the Krebs cycle.

    Fixation of mutations in human immunodeficiency virus type 1 (HIV-1), such as those conferring drug resistance and immune escape, can result in a change in replication fitness. To assess these changes, a real-time TaqMan PCR detection assay and statistical methods for data analysis were developed to estimate sensitively relative viral fitness in competitive viral replication experiments in cell culture. Chimeric viruses with the gene of interest in an HIV-1NL4-3 backbone were constructed in two forms, vifA (native vif gene in NL4-3) and vifB (vif gene with six synonymous nucleotide differences from vifA). Subsequently, mutations of interest were introduced into the chimeric viruses in NL4-3VifA backbones, and the mutants were competed against the chimera with the isogenic viral sequence in the NL4-3VifB backbone in cell culture. In order to assess subtle fitness differences, culture supernatants were sampled longitudinally, and the viruses differentially quantified using vifA- and vifB-specific primers in real-time PCR assays. Based on an exponential net growth model, the growth rate of each virus was determined and the fitness cost of the mutation(s) distinguishing the two viruses represented as the net growth rate difference between the mutant and the native variants. Using this assay, the fitness impact of eight amino acid substitutions was quantitated at highly conserved sites in HIV-1 Gag and Env.

    The effects of 2,4,6-trinitrotoluene (TNT) on indigenous soil populations and pure bacterial cultures were examined. The number of colony-forming units (CFU) appearing when TNT-contaminated soil was spread on 0.3% molasses plates decreased by 50% when the agar was amended with 67 {mu}g TNT mL{sup -1}, whereas a 99% reduction was observed when uncontaminated soil was plated. Furthermore, TNT-contaminated soil harbored a greater number of organisms able to grow on plates amended with greater than 10 {mu}g TNT mL{sup -1}. The percentage of gram-positive isolates was markedly less in TNT-contaminated soil (7%; 2 of 30) than in uncontaminated soil (61%; 20 of 33). Pseudomonas aeruginosa, Pseudomonas corrugate, Pseudomonasfluorescens and Alcaligenes xylosoxidans made up the majority of the gram-negative isolates from TNT-contaminated soil. Gram-positive isolates from both soils demonstrated marked growth inhibition when greater than 8-16 {mu}g TNT mL{sup -1} was present in the culture media. Most pure cultures of known aerobic gram-negative organisms readily degraded TNT and evidenced net consumption of reduced metabolites. However, pure cultures of aerobic gram-positive bacteria were sensitive to relatively low concentrations of TNT as indicated by the 50% reduction in growth and TNT transformation which was observed at approximately 10 {mu}g TNT mL{sup -1}. Most non-sporeforming gram-positive organisms incubated in molasses media amended with 80 {mu}g TNT mL{sup -1} or greater became unculturable, whereas all strains tested remained culturable when incubated in mineral media amended with 98 {mu}g TNT mL{sup -1}, indicating that TNT sensitivity is likely linked to cell growth. These results indicate that gram-negative organisms are most likely responsible for any TNT transformation in contaminated soil, due to their relative insensitivity to high TNT concentrations and their ability to transform TNT.

    Full Text Available Relational memory theory holds that the hippocampus supports, and amnesia following hippocampal damage impairs, memory for all manner of relations. Unfortunately, many studies of hippocampal-dependent memory have either examined only a single type of relational memory or conflated multiple kinds of relations. The experiments reported here employed a procedure in which each of several kinds of relational memory (spatial, associative, and sequential could be tested separately using the same materials. In Experiment 1, performance of amnesic patients with medial temporal lobe damage was assessed on memory for the three types of relations as well as for items. Compared to the performance of matched comparison participants, amnesic patients were impaired on all three relational tasks. But for those patients whose MTL damage was limited to the hippocampus, performance was relatively preserved on item memory as compared to relational memory, although still lower than that of comparison participants. In Experiment 2, study exposure was reduced for comparison participants, matching their item memory to the amnesic patients in Experiment 1. Relational memory performance of comparison subjects was well above amnesic patient levels, showing the disproportionate dependence of all three relational memory performances on the integrity of the hippocampus. Correlational analyses of the various task performances of comparison participants and of college-age participants showed that our measures of item memory were not influenced significantly by memory for associations among the items.

    An experiment for determining the laser-TIG hybrid welding characteristics was carried out in three kinds of hybrid methods: CO2 laser-TIG coaxial hybrid, CO2 laser-TIG paraxial hybrid and Nd: YAG laser-TIG paraxial hybrid. The experimental results indicate that hybrid welding has two welding mechanisms in CO2 laser-TIG hybrid welding: deep penetration welding and heat conduction welding. As the effect of the laser-induced keyhole, the arc root is condensed, the current density and penetration depth increase significantly, the welding characteristic is apt to deep penetration welding. When current increases to some degree, the keyhole induced by laser disappears, which produces a shallow penetration and wide bead. The weld exhibits heat conduction welding characteristics. Furthermore, the arc images and weld bead cross-sections of three kinds of hybrid manners were also compared and analyzed at different welding currents, which established the foundation for understanding the welding characteristics of laser-TIG hybrid welding comprehensively.

    Past studies using transgenic models of early-staged amyloid pathology, have suggested that the amyloid pathology progresses in a neurotransmitter-specific manner where cholinergic terminals appear most vulnerable, followed by glutamatergic terminals and finally by somewhat more resistant GABAergic terminals. To determine whether this neurotransmitter-specific progression persists at later pathological stages, presynaptic bouton densities, and the areas of occupation and localization of plaque adjacent dystrophic neurites were quantified in 18-month-old APP(K670N, M671L)+PS1(M146L) doubly transgenic mice. Quantification revealed that transgenic animals had significantly lower cholinergic, glutamatergic and GABAergic presynaptic bouton densities. Cholinergic and glutamatergic dystrophic neurites appear to be heavily influenced by fibrillar Abeta as both types displayed a decreasing area of occupation with respect to increasing plaque size. Furthermore, cholinergic dystrophic neurites reside in closer proximity to plaques than glutamatergic dystrophic neurites, while GABAergic dystrophic neurites were minimal regardless of plaque size. To investigate whether similarities exist in the human AD pathology, a monoclonal antibody (McKA1) against the human vesicular glutamate transporter 1 (VGluT1) was developed. Subsequent staining in AD brain tissue revealed the novel presence of glutamatergic dystrophic neurites, to our knowledge the first evidence of a structural glutamatergic deficit in the AD pathology.

    Full Text Available The increase of life expectancy has led to the increase of age-related diseases such as osteoporosis. Osteoporosis is characterized by bone weakening promoting the occurrence of fractures with defective bone regeneration. Men aged over 50 have a prevalence for osteoporosis of 20% which is related to a decline in sex hormones occurring during andropause or surgical orchidectomy. As we previously demonstrated in a mouse model for menopause in women that treatment with the neurohypophyseal peptide hormone oxytocin (OT normalizes body weight and prevents the development of osteoporosis, herein we addressed the effects of OT in male osteoporosis.Thus, we treated orchidectomized mice, an animal model suitable for the study of male osteoporosis, for 8 weeks with OT and then analyzed trabecular and cortical bone parameters as well as fat mass using micro-computed tomography. Orchidectomized mice displayed severe bone loss, muscle atrophy accompanied by fat mass gain as expected in andropause. Interestingly, OT treatment in male mice normalized fat mass as it did in female mice. However, although OT treatment led to a normalization of bone parameters in ovariectomized mice, this did not happen in orchidectomized mice. Moreover, loss of muscle mass was not reversed in orchidectomized mice upon OT treatment. All of these observations indicate that OT acts on fat physiology in both sexes, but in a sex specific manner with regard to bone physiology.

    Full Text Available INTRODUCTION : Percutaneous nephrolithotomy (PCNL is the most frequently performed surgery for stone disease at our institution. Nearly 100 PCNL procedures are being performed in a year at our institution. Septicemia following PCNL can be catastrophic despite sterile preoperative urine and prophylactic antibiotics. Infected stones, obstructed kidneys , and comorbidit y have been held responsible. In this study we analyzed various culture specimens, namely Mid - stream urine (MSU, renal pelvic urine and crushed stones. MATERIALS AND METHODS : We performed a prospective clinical study in all our patients undergoing PCNL b etween January 2013 and December 2014. MSU was sent for culture and sensitivity testing (C&S one day prior to surgery. Percutaneous access into the ipsilateral pelvicaliceal system is achieved under image intensification using a fine, 14 gauge Kellet need le. Urine from the pelvicaliceal system is first aspirated and sent as pelvic urine C&S. Stone fragments are collected to be proces0sed for C&S. The data collected were divided into 3 main groups, that is MSU C&S, pelvic urine C&S and stone C&S. RESULTS : A total of 83 patients were included in the study, of this MSU C&S was positive in 9/83 (10.8% patients, Pelvic C&S in 10 /73 (13.7% patients and Stone C&S in 25/83 (30.1% patients. Out of 25 cases of stone culture positive patients 17 patients develope d Systemic Inflammatory Response Syndrome (SIRS but only 2 patients developed SIRS in MSU C & S positive patients. CONCLUSIONS: The results of our study suggest that positive stone C&S is the better predictor of potential urosepsis than MSU. Stone cultur e is available only after surgery but appears to be the best guide for antibiotic therapy in case of sepsis. So the routine collection of stone for C&S will be beneficial

    Culture plays a crucial role in our lives. Depending on our cultural background, we judge on and react to everything that we encounter. Subtle differences in behavior can lead to misunderstandings or even culture shock. In a similar manner, virtual characters can be declined by certain user groups when showing culturally inappropriate behavior. But how can social aspects such as culture be integrated into the behavioral models of virtual characters Birgit Endrass addresses this question by carrying out a hybrid approach that is based on theoretical background from the social sciences as well a

    Full Text Available The accumulation of aggregated forms of the α-synuclein (αSN is associated with the pathogenesis of Parkinson’s disease (PD and Dementia with Lewy Bodies. The loss of synapses is an important event in the pathogenesis of these diseases. Here we show that aggregated recombinant human αSN, but not βSN, triggered synapse damage in cultured neurons as measured by the loss of synaptic proteins. Pre-treatment with the selective cytoplasmic phospholipase A2 (cPLA2 inhibitors AACOCF3 and MAFP protected neurons against αSN-induced synapse damage. Synapse damage was associated with the αSN-induced activation of synaptic cPLA2 and the production of prostaglandin E2. The activation of cPLA2 is the first step in the generation of platelet-activating factor (PAF and PAF receptor antagonists (ginkgolide B or Hexa-PAF also protect neurons against αSN-induced synapse damage. αSN-induced synapse damage was also reduced in neurons pre-treated with the cholesterol synthesis inhibitor (squalestatin. These results are consistent with the hypothesis that αSN triggered synapse damage via hyperactivation of cPLA2. They also indicate that αSN-induced activation of cPLA2 is influenced by the cholesterol content of membranes. Inhibitors of this pathway that can cross the blood brain barrier may protect against the synapse damage seen during PD.

    Telling the truth is one of the most respected virtues in medical history and one of the most emphasized in the code of medical ethics. Health care providers are frequently confronted with the dilemma as to whether or not to tell the truth. This dilemma deepens when both choices are critically vicious: The choice is no longer between "right and right" or "right and wrong," it is between "wrong and wrong." In the case presented and discussed in this paper, a research team in Saudi Arabia unintentionally uncovered information regarding misattributed paternity. In such a situation and in the context of a tribal cultural system, what should the team do with this information? This case analysis demonstrates the joint application of ethical resources originating from within and outside the Saudi Arabian context. The article analyses the case based on the moral problems involved, relevant medical application, and the impact of such information in the Saudi tribal and Islamic domains. The most pertinent relevant values and secular debates on similar matters are discussed. Finally, the article aims to provide an Islamic dimension of family, fatherhood, and adultery.

    Full Text Available On a large sample of 2288 Han Chinese undergraduates, we investigated how religion and DRD4 are related to human altruistic giving behavior as measured with the Andreoni-Miller Dictator Game. This game enables us to clearly specify (non-selfishness, efficiency, and fairness motives for sharing. Participants were further classified into religious categories (Christian, Buddhist-Tao, and No Religion based on self-reports, and genotyped for the dopamine D4 receptor (DRD4 gene exon III VNTR. Our analysis revealed a significant interaction between religion and DRD4 correlated with giving behavior solely among males: Whereas no significant association between religion and sharing decisions was observed in the majority 4R/4R genotype group, a significant difference in giving behavior between Christian and non-Christian males was seen in the non-4R/4R group, with Christian men being overall more altruistic (less selfish and fairer than non-Christian men. These results support the vantage sensitivity hypothesis regarding DRD4 that the non-4R/4R ‘susceptibility’ genotype is more responsive to a positive environment provided by some religions.

    Full Text Available Background: Clinical results of regenerative treatments for osteoarthritis are becoming increasingly significant. However, several questions remain unanswered concerning mesenchymal stem cell (MSC adhesion and incorporation into cartilage. Methods: To this end, peripheral blood (PB MSCs were chondrogenically induced and/or stimulated with pulsed electromagnetic fields (PEMFs for a brief period of time just sufficient to prime differentiation. In an organ culture study, PKH26 labelled MSCs were added at two different cell densities (0.5 x106 vs 1.0 x106. In total, 180 explants of six horses (30 per horse were divided into five groups: no lesion (i, lesion alone (ii, lesion with naïve MSCs (iii, lesion with chondrogenically-induced MSCs (iv and lesion with chondrogenically-induced and PEMF-stimulated MSCs (v. Half of the explants were mechanically loaded and compared with the unloaded equivalents. Within each circumstance, six explants were histologically evaluated at different time points (day 1, 5 and 14. Results: COMP expression was selectively increased by chondrogenic induction (p = 0.0488. PEMF stimulation (1mT for 10 minutes further augmented COL II expression over induced values (p = 0.0405. On the other hand, MSC markers remained constant over time after induction, indicating a largely predifferentiated state. In the unloaded group, MSCs adhered to the surface in 92.6% of the explants and penetrated into 40.7% of the lesions. On the other hand, physiological loading significantly reduced surface adherence (1.9% and lesion filling (3.7% in all the different conditions (p Conclusion: The present study demonstrates that primed chondrogenic induction of MSCs at a lower cell density without loading results in significantly enhanced and homogenous MSC adhesion and incorporation into equine cartilage.

    2012-01-01

    The incidence of cardiac hypertrophy, an established risk factor for heart failure, is generally lower in women compared with men, but this advantage is lost after menopause. Although it is widely believed that estrogens are cardioprotective, there are contradictory reports, including increased cardiac events in postmenopausal women receiving estrogens and enhanced cardiac protection from ischemic injury in female mice without estrogens. We exposed aromatase knockout (ArKO) mice, which produce no estrogens, to both pathologic and physiologic stimuli. This model allows an investigation into the effects of a complete, chronic lack of estrogens in male and female hearts. At baseline, female ArKO mice had normal-sized hearts but decreased cardiac function and paradoxically increased phosphorylation of many progrowth kinases. When challenged with the pathological stimulus, isoproterenol, ArKO females developed 2-fold more hypertrophy than wild-type females. In contrast, exercise-induced physiological hypertrophy was unaffected by the absence of estrogens in either sex, although running performance was blunted in ArKO females. Thus, loss of estrogen signaling in females, but not males, impairs cardiac function and sensitizes the heart to pathological insults through up-regulation of multiple hypertrophic pathways. These findings provide insight into the apparent loss of cardioprotection after menopause and suggest that caution is warranted in the long-term use of aromatase inhibitors in the setting of breast cancer prevention.

    Full Text Available The title of this study directly refers to the importance of the images, meaning material objects, personal memories or literal images – photographs one elects from the past in order to build up the individual identity and present it to others. Long ago, during the antique age, techniques of the remembrance by using pictorial memory and sequencing images from the past had been created, and those just developed during centuries. The goal of this paper is to stress that, basic concepts of the self representation did not change, but just used different media through time. In the first part of the paper, the difference between terms memory and remembrance, their relation to the culture and reasons why one remembers something will be discussed. As it is tended to be shown, the remembrance is always “pictorial”, one always puts elected images of the past in the exact order and creates its own identity. Therefore, in the second part of this study, the idea of individual identity, creation of it and the representation of the self identity to the others will be examined and explained in the context of the pictorial memory and heritage on the one hand, and social determination on the other. Inspired by the wholes one leaves in its personal life story when presenting it to others, the need of forgetting as constituent part of memory will also be stressed. Finally, the last part of this study points out that we still use the same concepts of remembering, electing and presenting images from the past in the creation of the image of ourselves, using the most popular media today - virtual space.

    Aspirin has provided clear benefits to human health. But salicylic acid (SAL) -the main aspirin biometabolite- exerts several effects on eukaryote and prokaryote cells. SAL can affect, for instance, the expression of Staphylococcus aureus virulence factors. SAL can also form complexes with iron cations and it has been shown that different iron chelating molecules diminished the formation of S. aureus biofilm. The aim of this study was to elucidate whether the iron content limitation caused by SAL can modify the S. aureus metabolism and/or metabolic regulators thus changing the expression of the main polysaccharides involved in biofilm formation. The exposure of biofilm to 2 mM SAL induced a 27% reduction in the intracellular free Fe2+ concentration compared with the controls. In addition, SAL depleted 23% of the available free Fe2+ cation in culture media. These moderate iron-limited conditions promoted an intensification of biofilms formed by strain Newman and by S. aureus clinical isolates related to the USA300 and USA100 clones. The slight decrease in iron bioavailability generated by SAL was enough to induce the increase of PIA expression in biofilms formed by methicillin-resistant as well as methicillin-sensitive S. aureus strains. S. aureus did not produce capsular polysaccharide (CP) when it was forming biofilms under any of the experimental conditions tested. Furthermore, SAL diminished aconitase activity and stimulated the lactic fermentation pathway in bacteria forming biofilms. The polysaccharide composition of S. aureus biofilms was examined and FTIR spectroscopic analysis revealed a clear impact of SAL in a codY-dependent manner. Moreover, SAL negatively affected codY transcription in mature biofilms thus relieving the CodY repression of the ica operon. Treatment of mice with SAL induced a significant increase of S aureus colonization. It is suggested that the elevated PIA expression induced by SAL might be responsible for the high nasal colonization

    We have previously described the application of an automated microculture tetrazolium assay (MTA) involving dimethyl sulfoxide solubilization of cellular-generated 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)-formazan to the in vitro assessment of drug effects on cell growth (M.C. Alley et al., Proc. Am. Assoc. Cancer Res., 27:389, 1986; M.C. Alley et al., Cancer Res. 48:589-601, 1988). There are several inherent disadvantages of this assay, including the safety hazard of personnel exposure to large quantities of dimethyl sulfoxide, the deleterious effects of this solvent on laboratory equipment, and the inefficient metabolism of MTT by some human cell lines. Recognition of these limitations prompted development of possible alternative MTAs utilizing a different tetrazolium reagent, 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl] -2H- tetrazolium hydroxide (XTT), which is metabolically reduced in viable cells to a water-soluble formazan product. This reagent allows direct absorbance readings, therefore eliminating a solubilization step and shortening the microculture growth assay procedure. Most human tumor cell lines examined metabolized XTT less efficiently than MTT; however, the addition of phenazine methosulfate (PMS) markedly enhanced cellular reduction of XTT. In the presence of PMS, the XTT reagent yielded usable absorbance values for growth and drug sensitivity evaluations with a variety of cell lines. Depending on the metabolic reductive capacity of a given cell line, the optimal conditions for a 4-h XTT incubation assay were 50 micrograms of XTT and 0.15 to 0.4 microgram of PMS per well. Drug profiles obtained with representative human tumor cell lines for several standard compounds utilizing the XTT-PMS methodology were similar to the profiles obtained with MTT. Addition of PMS appeared to have little effect on the metabolism of MTT. The new XTT reagent thus provides for a simplified, in vitro cell growth assay

    Full Text Available Turkish steppe culture constituted a typical structure with regard to its creation and development. It emerged from steppe geography. The geography affected social, politic, economical, military and religious structure of the society substantially. The Turkish culture was shaped up under these influences. The agents of the culture appeared as a shepherd generally. Shepherding provided a basic to the animal husbandry. The shepherds headed to search the fertile grass. Shepherding obliged people to became seminomadic. Thus the life continued in a manner of searching new pastures and shuttling between plateau and winter quarters . The horse that is one of the important ingredient of the culture provided mobility and speed to the culture. In social, politic, and military life of society the horse came into prominence. The nomadic houses or the cars contributed to Turks’ life very much. These nomad houses were shelter at the nights and cold days for them. Going from the plateau to winter quarters and from pasture to another pasture was made easy thanks to these. The finding which took out from graves reflects to all features of the culture.The ruins of nomad houses and horses were arised from the graves . These support the informations which was given in the written sources. Among the findings, there were also The animal struggle scenes which reflect art concept of theseminomadism between tomb finds. This art concept named as turkish animal style. It’s tried to determine The scope of the Turkish culture by emphasizing steppe, shepherding, semi-nomadism, horse, nomad house, tomb. It is also emphasized that aforementioned notions can be used for Turkish culture. Thus, cultural dysphemisms in the turkish culture based on that idea.

  10. The glucocorticoid receptor 1A3 promoter correlates with high sensitivity to glucocorticoid-induced apoptosis in human lymphocytes.

    Glucocorticoids (GCs) are powerful inhibitors of inflammation and immunity. Although glucocorticoid-induced cell death (GICD) is an important part of GCs actions, the cell types and molecular mechanisms involved are not well understood. Untranslated exon 1A3 of the human glucocorticoid receptor (GR) gene is a major determinant of GICD in GICD-sensitive human cancer cell lines, operating to dynamically upregulate GR levels in response to GCs. We measured the GICD sensitivity of freshly isolated peripheral blood mononuclear cells and thymocytes to dexamethasone in vitro, relating this to GR exon 1A3 expression. A clear GICD sensitivity hierarchy was detected: B cells>thymocytes/natural killer (NK) cells>peripheral T cells. Within thymocyte populations, GICD sensitivity decreased with maturation. Interestingly, NK cell subsets were differentially sensitive to GICD, with CD16(+)CD56(int) (cytotoxic) NK cells being highly resistant to GICD, whereas CD16(-)CD56(hi) (cytokine producing) NK cells were highly sensitive (similar to B cells). B-cell GICD was rescued by co-culture with interleukin-4. Strikingly, although no significant increases in GR protein were observed during 48 h of culture of GICD-sensitive and -resistant cells alike, GR 1A3 expression was increased over pre-culture levels in a manner directly proportional to the GICD sensitivity of each cell type. Accordingly, this is the first evidence that the GR exon 1A3 promoter is differentially regulated during thymic development and maturation of human T cells. Furthermore, human peripheral blood B cells are exquisitely GICD-sensitive in vitro, giving new insight into how GCs may downregulate immunity. Collectively, these data show that GR 1A3 expression is tied with GICD sensitivity in human lymphocytes, underscoring the potential for GR 1A3 expression to be used as a biomarker for sensitivity to GICD.

    The metalloid arsenic is a worldwide environmental toxicant, exposure to which is associated with many adverse outcomes. Arsenic is also an effective therapeutic agent in certain disease settings. Arsenic was recently shown to regulate the activity of the Hedgehog (HH) signal transduction pathway, and this regulation of HH signaling was proposed to be responsible for a subset of arsenic's biologic effects. Surprisingly, these separate reports proposed contradictory activities for arsenic, as either an agonist or antagonist of HH signaling. Here we provide in vitro and in vivo evidence that arsenic acts as a modulator of the activity of the HH effector protein glioma-associated oncogene family zinc finger (GLI), activating or inhibiting GLI activity in a context-dependent manner. This arsenic-induced modulation of HH signaling is observed in cultured cells, patients with colorectal cancer who have received arsenic-based therapy, and a mouse colorectal cancer xenograft model. Our results show that arsenic activates GLI signaling when the intrinsic GLI activity is low but inhibits signaling in the presence of high-level GLI activity. Furthermore, we show that this modulation occurs downstream of primary cilia, evidenced by experiments in suppressor of fused homolog (SUFU) deficient cells. Combining our findings with previous reports, we present an inclusive model in which arsenic plays dual roles in GLI signaling modulation: when GLIs are primarily in their repressor form, arsenic antagonizes their repression capacity, leading to low-level GLI activation, but when GLIs are primarily in their activator form, arsenic attenuates their activity.

    Background The extracellular matrix (ECM) produced by dermal fibroblasts supports skin structure, and degradation and/or reduced production of ECM are the main causes of wrinkle formation. Objective The aim of this study was to identify the active ingredient that enhances ECM production in dermal fibroblasts. Methods Polarity-based fractionation was used to isolate the active ingredient from natural extracts, and the effects of cedrol (isolated from Pterocarpus indicusirginia) on ECM production in cultured human dermal fibroblasts was investigated by reverse transcription-polymerase chain reaction, enzyme linked immunosorbent assay, and Western blot analysis. Results Cedrol accelerated fibroblast growth in a dose-dependent manner and increased the production of type 1 collagen and elastin. Phosphorylation of p42/44 extracellular signal-regulated kinase, p38 mitogen-activated protein kinase, and Akt was markedly increased by cedrol, indicating that enhanced ECM production is linked to activation of intracellular signaling cascades. Conclusion These results indicate that cedrol stimulates ECM production, with possible applications to the maintenance of skin texture. PMID:22363150

  14. HAb18G/CD147 cell-cell contacts confer resistance of a HEK293 subpopulation to anoikis in an E-cadherin-dependent manner

    Full Text Available Abstract Background Acquisition of resistance to "anoikis" facilitates the survival of cells under independent matrix-deficient conditions, such as cells in tumor progression and the production of suspension culture cells for biomedical engineering. There is evidence suggesting that CD147, an adhesion molecule associated with survival of cells in tumor metastasis and cell-cell contacts, plays an important role in resistance to anoikis. However, information regarding the functions of CD147 in mediating cell-cell contacts and anoikis-resistance remains limited and even self-contradictory. Results An anoikis-resistant clone (HEK293ar, derived from anoikis-sensitive parental Human Embryonic Kidney 293 cells, survived anoikis by the formation of cell-cell contacts. The expression of HAb18G/CD147 (a member of the CD147 family was upregulated and the protein was located at cell-cell junctions. Upregulation of HAb18G/CD147 in suspended HEK293ar cells suppressed anoikis by mediating the formation of cell-cell adhesions. Anoikis resistance in HEK293ar cells also required E-cadherin-mediated cell-cell contacts. Knock-down of HAb18G/CD147 and E-cadherin inhibited cell-cell contacts formation and increased anoikis sensitivity respectively. When HAb18G/CD147 was downregulated, E-cadherin expression in HEK293ar cells was significantly suppressed; however, knockdown of E-cadherin by E-cadherin siRNA or blocking of E-cadherin binding activity with a specific antibody and EDTA had no significant effect on HAb18G/CD147 expression. Finally, pretreatment with LY294002, a phosphoinositide 3-kinase (PI3K/AKT inhibitor, disrupted cell-cell contacts and decreased cell number, but this was not the case in cells treated with the extracellular signal-regulated kinase (ERK inhibitor PD98059. Conclusions Our results provide new evidence that HAb18G/CD147-mediated cell-cell contact confers anoikis resistance in an E-cadherin-dependent manner; and cell-cell contact mediated

    Androgen receptor (AR) plays an important regulatory role in prostate cancer. AR's transcriptional activity is regulated by androgenic ligands, but also by post-translational modifications, such as SUMOylation. To study the role of AR SUMOylation in genuine chromatin environment, we compared androgen-regulated gene expression and AR chromatin occupancy in PC-3 prostate cancer cell lines stably expressing wild-type (wt) or doubly SUMOylation site-mutated AR (AR-K386R,K520R). Our genome-wide gene expression analyses reveal that the SUMOylation modulates the AR function in a target gene and pathway selective manner. The transcripts that are differentially regulated by androgen and SUMOylation are linked to cellular movement, cell death, cellular proliferation, cellular development and cell cycle. Fittingly, SUMOylation mutant AR cells proliferate faster and are more sensitive to apoptosis. Moreover, ChIP-seq analyses show that the SUMOylation can modulate the chromatin occupancy of AR on many loci in a fashion that parallels their differential androgen-regulated expression. De novo motif analyses reveal that FOXA1, C/EBP and AP-1 motifs are differentially enriched at the wtAR- and the AR-K386R,K520R-preferred genomic binding positions. Taken together, our data indicate that SUMOylation does not simply repress the AR activity, but it regulates AR's interaction with the chromatin and the receptor's target gene selection.

    Objectives To identify species and antibiotic sensitivity of the microorganisms in air samples from a cell cul ture laboratory and to determine changes in their number before and after laboratory work by technicians as well as after disinfection with ultraviolet radiation or fumigation with methanal. Methods Microorganisms in the air samples from the laboratory were collected by the natural sedimentation method before and after laboratory work by technicians as well as after disinfection with ultraviolet radiation or fumigation with methanal. They were then cultured, identified, and tested against antibiotics. The number of microbe colonies cultured in medium was counted at different times. Results There were 54,205 microbe colonies in the culture medium before and after laboratory work by technicians and 42 after disinfection. There were 22 species of bacteria that included microbes from 12 genera and 2 species of fungi. Among these bacteria species, there were 13 species of Gram-positive bacilli from 6 genera and 9 species of Gram-negative bacilli from 6 genera. The predominant microbes were M. luteus, S. saccharolyticus, Cedecea species 3, and S. epidermidis. The antibiotics sensitivity test showed these four bacteria species, i. e. M. luteus, S, saccharolyticus, Cedecea species 3, and S. capitis, were not drug-resistant. Four of the isolated microbes were resistant to 1 antibiotic, 4 were resistant to 2 antibiotics , and 8 were resistant to 4 antibiotics. Conclusion The number of microorganisms in the air samples from the cell culture laboratory varied greatly with work by technicians. The most common microbes are still sensitive to common antimicrobials. The number of microorganisms in the air of a cell culture laboratory can easily be decreased by ultraviolet radiation or fumigation with methanal.%目的 研究细胞培养室内空气中微生物种类及药物敏感性,人员操作前、后和采用紫外线照射或甲醛熏蒸消毒后数量变化情况.

    The supernumerary chromosome 21 in Down syndrome differentially affects the methylation statuses at CpG dinucleotide sites and creates genome-wide transcriptional dysregulation of parental alleles, ultimately causing diverse pathologies. At present, it is unknown whether those effects are dependent or independent of the parental origin of the nondisjoined chromosome 21. Linkage analysis is a standard method for the determination of the parental origin of this aneuploidy, although it is inadequate in cases with deficiency of samples from the progenitors. Here, we assessed the reliability of the epigenetic 5mCpG imprints resulting in the maternally (oocyte)-derived allele methylation at a differentially methylated region (DMR) of the candidate imprinted WRB gene for asserting the parental origin of chromosome 21. We developed a methylation-sensitive restriction enzyme-specific PCR assay, based on the WRB DMR, across single nucleotide polymorphisms (SNPs) to examine the methylation statuses in the parental alleles. In genomic DNA from blood cells of either disomic or trisomic subjects, the maternal alleles were consistently methylated, while the paternal alleles were unmethylated. However, the supernumerary chromosome 21 did alter the methylation patterns at the RUNX1 (chromosome 21) and TMEM131 (chromosome 2) CpG sites in a parent-of-origin-independent manner. To evaluate the 5mCpG imprints, we conducted a computational comparative epigenomic analysis of transcriptome RNA sequencing (RNA-Seq) and histone modification expression patterns. We found allele fractions consistent with the transcriptional biallelic expression of WRB and ten neighboring genes, despite the similarities in the confluence of both a 17-histone modification activation backbone module and a 5-histone modification repressive module between the WRB DMR and the DMRs of six imprinted genes. We concluded that the maternally inherited 5mCpG imprints at the WRB DMR are uncoupled from the parental allele

In 2007-2008, trained moderators conducted eight focus groups with nonsmokers (n = 47) of Korean descent in San Diego. Participants discussed their personal experiences and views concerning SHS. Most participants detected SHS quickly and disliked the smell. Their reactions differed by gender, age, and how well they knew the smoker. Reactions ranged from passive (e.g., tolerating SHS or staring) to assertive (moving or asking the smoker to stop smoking). Younger participants were more tolerant than older participants. Participants appeared caught between two cultures. Despite high awareness, they struggled with how to avoid SHS in a manner befitting of their social status and Korean values. Culturally sensitive programs are needed for immigrants such as Koreans in the United States.

    Staphylococcus aureus is a major human pathogen and a common cause of nosocomial infections. This facultative pathogen produces a large arsenal of virulence factors, including the haemolysins, which allow the bacterium to lyse erythrocytes and thereby release large amounts of the haem-containing haemoglobin. The released haem is thought to be the main iron source of this organism during the course of infection, and is considered to be crucial for bacterial proliferation in vivo. High concentrations of haem and its degradation products, on the other hand, are known to be toxic for S. aureus, making it essential for the pathogen to tightly control haem release from red blood cells. Here we show that S. aureus responds to haemin by downregulating the expression of haemolysins. Subinhibitory concentrations of haemin were found to significantly reduce transcription of the haemolysin genes hlb (encoding β-haemolysin) and hlgA (encoding the S-class component of γ-haemolysin), while hla (encoding α-haemolysin) and RNAIII (encoding δ-haemolysin) transcription did not appear to be affected. The presence of haemin also reduced the haemolytic potential of the supernatants of S. aureus LS1 cultures. Inactivation of the sae locus in LS1 abolished the haemin effect on the transcription of haemolysin genes, indicating that the two-component regulatory system is required for this regulatory effect. Iron limitation, on the other hand, was found to induce the expression of haemolysins, and this effect was again abolished in the sae mutant, indicating that S. aureus modulates its haemolysin production in response to iron and haem availability in an Sae-dependent manner.

    2011-11-09

    Warming observed thus far is entirely consistent with low climate sensitivity. However, the result is ambiguous because the sources of climate change are numerous and poorly specified. Model predictions of substantial warming aredependent on positive feedbacks associated with upper level water vapor and clouds, but models are notably inadequate in dealing with clouds and the impacts of clouds and water vapor are intimately intertwined. Various approaches to measuring sensitivity based on the physics of the feedbacks will be described. The results thus far point to negative feedbacks. Problems with these approaches as well as problems with the concept of climate sensitivity will be described.

    Diabetes mellitus (DM) is a disease of increasing incidence and prevalence. Arterial baroreceptors are stretch-sensitive receptors, which in a reflex manner are involved in the homeostatic control of arterial blood pressure. Diabetic subjects have depressed baroreflex sensitivity (BRS), although the exact pathomechanisms are unclear. In this review, we discuss the features, clinicaland prognostic implications of reduced BRS for diabetic patients and the potential involvement of cardiovascular autonomic neuropathy and atherosclerosis. Finally, we demonstrate evidence on interventions (e.g. pioglitazone, alpha-lipoic acid, leptin, fluvastatin, physicaltraining etc.) which could improve BRS and ameliorate cardiovascular autonomic dysfunction in diabetic patients.

  16. Zinc Modulates Nanosilver-Induced Toxicity in Primary Neuronal Cultures.

    Ziemińska, Elżbieta; Strużyńska, Lidia

    2016-02-01

    Silver nanoparticles (NAg) have recently become one of the most commonly used nanomaterials. Since the ability of nanosilver to enter the brain has been confirmed, there has been a need to investigate mechanisms of its neurotoxicity. We previously showed that primary neuronal cultures treated with nanosilver undergo destabilization of calcium homeostasis via a mechanism involving glutamatergic NMDA receptors. Considering the fact that zinc interacts with these receptors, the aim of the present study was to examine the role of zinc in mechanisms of neuronal cell death in primary cultures. In cells treated with nanosilver, we noted an imbalance between extracellular and intracellular zinc levels. Thus, the influence of zinc deficiency and supplementation on nanosilver-evoked cytotoxicity was investigated by treatment with TPEN (a chelator of zinc ions), or ZnCl(2), respectively. Elimination of zinc leads to complete death of nanosilver-treated CGCs. In contrast, supplementation with ZnCl(2) increases viability of CGCs in a dose-dependent manner. Addition of zinc provided protection against the extra/intracellular calcium imbalance in a manner similar to MK-801, an antagonist of NMDA receptors. Zinc chelation by TPEN decreases the mitochondrial potential and dramatically increases the rate of production of reactive oxygen species. Our results indicate that zinc supplementation positively influences nanosilver-evoked changes in CGCs. This is presumed to be due to an inhibitory effect on NMDA-sensitive calcium channels.

  17. Culture-independent analysis of probiotic products by denaturing gradient gel electrophoresis.

    2003-01-01

    In order to obtain functional and safe probiotic products for human consumption, fast and reliable quality control of these products is crucial. Currently, analysis of most probiotics is still based on culture-dependent methods involving the use of specific isolation media and identification of a limited number of isolates, which makes this approach relatively insensitive, laborious, and time-consuming. In this study, a collection of 10 probiotic products, including four dairy products, one fruit drink, and five freeze-dried products, were subjected to microbial analysis by using a culture-independent approach, and the results were compared with the results of a conventional culture-dependent analysis. The culture-independent approach involved extraction of total bacterial DNA directly from the product, PCR amplification of the V3 region of the 16S ribosomal DNA, and separation of the amplicons on a denaturing gradient gel. Digital capturing and processing of denaturing gradient gel electrophoresis (DGGE) band patterns allowed direct identification of the amplicons at the species level. This whole culture-independent approach can be performed in less than 30 h. Compared with culture-dependent analysis, the DGGE approach was found to have a much higher sensitivity for detection of microbial strains in probiotic products in a fast, reliable, and reproducible manner. Unfortunately, as reported in previous studies in which the culture-dependent approach was used, a rather high percentage of probiotic products suffered from incorrect labeling and yielded low bacterial counts, which may decrease their probiotic potential.

  18. Transdifferentiated rat pancreatic progenitor cells (AR42J-B13/H) respond to phenobarbital in a rat hepatocyte-specific manner.

    2016-07-01

    Phenobarbital (PB) is known to produce species-specific effects in the rat and mouse, being carcinogenic in certain mouse strains, but only in rats if treated after a DNA damaging event. PB treatment in the rat and mouse also produces disparate effects on cell signalling and miRNA expression profiles. These responses are induced by short term and prolonged PB exposure, respectively, with the latter treatments being difficult to examine mechanistically in primary hepatocytes due to rapid loss of the original hepatic phenotype and limited sustainability in culture. Here we explore the rat hepatocyte-like B13/H cell line as a model for hepatic response to PB exposure in both short-term and longer duration treatments. We demonstrate that PB with Egf treatment in the B13/H cells resulted in a significant increase in Erk activation, as determined by the ratio of phospho-Erk to total Erk, compared to Egf alone. We also show that an extended treatment with PB in the B13/H cells produces a miRNA response similar to that seen in the rat in vivo, via the time-dependent induction of miR-182/96. Additionally, we confirm that B13/H cells respond to Car activators in a typical rat-specific manner. These data suggest that the B13/H cells produce temporal responses to PB that are comparable to those reported in short-term primary rat hepatocyte cultures and in the longer term are similar to those in the rat in vivo. Finally, we also show that Car-associated miR-122 expression is decreased by PB treatment in B13/H cells, a PB-induced response that is common to the rat, mouse and human. We conclude that the B13/H cell system produces a qualitative response comparable to the rat, which is different to the response in the mouse, and that this model could be a useful tool for exploring the functional consequences of PB-sensitive miRNA changes and resistance to PB-mediated tumours in the rat.

    Full Text Available Abstract: Root cultures of Withania coagulans (Solanaceae were obtained from in vitro germinated sterile plantlets. The roots grew axenically in MS medium containing 0.25 mgL-1 indole-3-butyric acid and 30 gL-1 sucrose. A RP-HPLC method for the determination of withanolides in plant tissues was developed using a binary gradient solvent system comprising acetonitrile and water containing 0.1% (v/v acetic acid. The method was validated according to ICH guidelines. The linearity was found to be in the range of 1.2-720 µLmL-1. The method described is simple, sensitive, accurate and reproducible. The developed method was applied for quantification of withanolides level in cultured roots of W. coagulans. The root cultures synthesized withanolides of which withaferin A was the major compound. The productivity of withaferin A in the three-week-old cultured roots was 11.65 µgg-1. Withaferin A production showed consistent increase with root growth during the three weeks of culture period.   Industrial relevance: Plant tissue culture can be a potential source for important secondary metabolites such as pharmaceuticals and food additives. This technology depends on using plant cultures in a similar manner to microbial fermentation for factory-type production of target metabolites. The technology bears many advantages over conventional agricultural methods: production is independent of variation in crop quality or failure, yield of target compounds would be constant and geared to demand, there is no difficulty in applying good manufacturing practice to the early stages of production, production would be possible anywhere under strictly controlled conditions, independency of political problems, free from risk of contamination with pesticides, herbicides, agrochemicals or fertilizers and new methods of production can be patented.

    The concepts of nuclear safety and security culture are well established; however, a common understanding of safeguards culture is not internationally recognized. Supported by the National Nuclear Security Administration, the authors prepared this report, an analysis of the concept of safeguards culture, and gauged its value to the safeguards community. The authors explored distinctions between safeguards culture, safeguards compliance, and safeguards performance, and evaluated synergies and differences between safeguards culture and safety/security culture. The report concludes with suggested next steps.

    For different delay models,the concept of sensitization can be very different.Traditonal concepts of sensitization cannot precisely describe circuit behavior when the input vectors change very fast.Using Boolean process aporoach,this paper presents a new definition of sensitization for arbitrary input waveforms.By this new concept it is found that if the inputs of a combinational circuit can change at any time,and each gate's delay varies within an interval (bounded gate delay model),then every path,which is not necessarily a single topological path,is sensitizable.From the experimental results it can be seen that,all nonsensitizable paths for traditional concepts actually can propagate transitions along them for some input waveforms.However,specified time between input transitions(STBIT) and minimum permissible pulse width(ε)are two major factors to make some paths non-sensitizable.

  2. Navigating the ethics of cross-cultural health promotion research.

    Haintz, Greer Lamaro; Graham, Melissa; McKenzie, Hayley

    2015-12-01

    Health promotion researchers must consider the ethics of their research, and are usually required to abide by a set of ethical requirements stipulated by governing bodies (such as the Australian National Health and Medical Research Council) and human research ethics committees (HRECs). These requirements address both deontological (rule-based) and consequence-based issues. However, at times there can be a disconnect between the requirements of deontological issues and the cultural sensitivity required when research is set in cultural contexts and settings etic to the HREC. This poses a challenge for health promotion researchers who must negotiate between meeting both the requirements of the HREC and the needs of the community with whom the research is being conducted. Drawing on two case studies, this paper discusses examples from cross-cultural health promotion research in Australian and international settings where disconnect arose and negotiation was required to appropriately meet the needs of all parties. The examples relate to issues of participant recruitment and informed consent, participants under the Australian legal age of consent, participant withdrawal when this seemingly occurs in an ad hoc rather than a formal manner and reciprocity. Although these approaches are context specific, they highlight issues for consideration to advance more culturally appropriate practice in research ethics and suggest ways a stronger anthropological lens can be applied to research ethics to overcome these challenges.

    Full Text Available Cultural orientations of an organization can be its greatest strength, providing the basis for problem solving, cooperation, and communication. Culture, however, can also inhibit needed changes. Cultural changes typically happen slowly – but without cultural change, many other organizational changes are doomed to fail. The dominant culture of an organization is a major contributor to its success. But, of course, no organizational culture is purely one type or another. And the existence of secondary cultures can provide the basis for change. Therefore, organizations need to understand the cultural environments and values.

    herds had SCC levels below 400,000 ml-1. S. aureus and S. agalactiae were isolated from five of the nine herds with high SCC, S. agalactiae from one and S. aureus from three. Six herds had SSC below 200,000 ml-1. S. aureus and S. agalactiae were isolated from one, S. aureus from three, while the other two were negative for both pathogens. The results of herds A, B, C and D sampled at the farms showed that S. aureus was isolated from 1.8%, 19.2%, 17.0% and 8.4% of the animals and 0.9%, 5.9%, 5.4% and 2.2% of the mammary quarters, respectively. S. agalactiae was isolated from herds A, C and D. Within these herds the percentages of isolation were, respectively, 1.8%, 10.6% and 8.4% for the cows and 0.46%, 3.8% and 3.7% for the mammary quarters. S. aureus was recovered from all three bulk tank cultures from herds A, B and D. Only the third sample from herd C was positive for S. aureus. S. agalactiae was recovered from all samples collected from herd D, two samples from herd C and one sample from herd A. Coliforms were isolated from all tank samples from herds A, B, C and D and from all but one sample collected in the processing plant. Yeasts were recovered from 16 herds sampled at the processing plant and from all tank samples from herds A, B, C, and D. Neither coliforms or yeasts were isolated from the individual animals of herds A, B, C and D. These findings indicate that the milk was contaminated during or after milking, probably due to deficient hygiene and cleaning procedures. The analysis of the bulk tank milk cultures showed that the test was sensitive enough to detect contagious mastitis pathogens. The sensitivity of the test increased when more than two consecutive samples were examined.

  5. Influence of melatonin on the development of functional nicotinic acetylcholine receptors in cultured chick retinal cells

    Directory of Open Access Journals (Sweden)

    L.F.S. Sampaio

    2005-04-01

    Full Text Available The influence of melatonin on the developmental pattern of functional nicotinic acetylcholine receptors was investigated in embryonic 8-day-old chick retinal cells in culture. The functional response to acetylcholine was measured in cultured retina cells by microphysiometry. The maximal functional response to acetylcholine increased 2.7 times between the 4th and 5th day in vitro (DIV4, DIV5, while the Bmax value for [125I]-alpha-bungarotoxin was reduced. Despite the presence of alpha8-like immunoreactivity at DIV4, functional responses mediated by alpha-bungarotoxin-sensitive nicotinic acetylcholine receptors were observed only at DIV5. Mecamylamine (100 µM was essentially without effect at DIV4 and DIV5, while dihydro-ß-erythroidine (10-100 µM blocked the response to acetylcholine (3.0 nM-2.0 µM only at DIV4, with no effect at DIV5. Inhibition of melatonin receptors with the antagonist luzindole, or melatonin synthesis by stimulation of D4 dopamine receptors blocked the appearance of the alpha-bungarotoxin-sensitive response at DIV5. Therefore, alpha-bungarotoxin-sensitive receptors were expressed in retinal cells as early as at DIV4, but they reacted to acetylcholine only after DIV5. The development of an alpha-bungarotoxin-sensitive response is dependent on the production of melatonin by the retinal culture. Melatonin, which is produced in a tonic manner by this culture, and is a key hormone in the temporal organization of vertebrates, also potentiates responses mediated by alpha-bungarotoxin-sensitive receptors in rat vas deferens and cerebellum. This common pattern of action on different cell models that express alpha-bungarotoxin-sensitive receptors probably reflects a more general mechanism of regulation of these receptors.

    Humans are a cultural species, constantly navigating a complex web of culturally bound practices, norms, and worldviews. This article provides a brief overview of the relatively young field of cultural psychology, which investigates the many ways psychology and culture interweave with one another. Highlighting the cultural nature of the human species, it draws upon research on cultural evolution, enculturation, and developmental processes. This review further summarizes a number of cultural differences in how people perceive the self, and the behavioral consequences that follow from these differences, in the domains of internal and external attribution styles, motivations for self-enhancement, approach/avoidance, primary and secondary control, as well as motivations for distinctiveness and conformity. Additionally, the review discusses research on the intersection of culture and emotion, as well as cultural differences in cognition, perception, and reasoning.

    Background We live in an age when education is being internationalized. This can confront students with ‘cultural hegemony’ that can result from the unequal distribution of power and privilege in global society. The name that is given to awareness of social inequality is ‘critical consciousness’. Cross-cultural dialogue provides an opportunity for learners to develop critical consciousness to counter cultural hegemony. The purpose of this research was to understand how learners engage with cross-cultural dialogue, so we can help them do so more effectively in the future. Method The setting for this research was an online discussion in an international health professions educator fellowship program. We introduced scenarios with cultural references to study the reaction of participants to cultural conversation cues. We used an inductive thematic analysis to explore power and hegemony issues. Results Participants reflected that personally they were more likely to take part in cross-cultural discussions if they recognized the context discussed or had prior exposure to educational settings with cultural diversity. They identified barriers as lack of skills in facilitating cross-cultural discussions and fear of offending others. They suggested deliberately introducing cultural issues throughout the curriculum. Conclusion Our results indicate that developing critical consciousness and cross-cultural competency will require instructional design to identify longitudinal opportunities to bring up cross-cultural issues, and training facilitators to foster cross-cultural discussions by asking clarifying questions and navigating crucial/sensitive conversations.

    2011-01-01

    International business negotiation is playing a more and more important role in modem society.We can see clearly that there are great differences in international business negotiation.Specially,culture can influence negotiating styles in different ways,because negotiators from another nation are different in language,beliefs,behaviors manners,and way of thinking,value and attitudes and so on.Different cultures express different ways of doing business.Even though negotiators are well prepared,it is not so easy to reach a satisfactory agreement between negotiators across cultures.Negotiations can be easily broken down due to a lack of mutual understanding of the cultures.Culture affects negotiation even before negotiators meet face to face.Therefore,learning the opponent’s culture and having a good understanding of how cultural differences affect negotiation will be critically important if one wants to succeed in cross-cultural negotiations.

    The contention of this paper is that the context of social and therapeutic problems is critical to their resolution, and that many of them stem from historical and structural injustice. It focuses on the contextual issues of cultural, gender, and socioeconomic equity as providing important insights into authentic notions of social inclusion and well-being, and encourages therapists, service providers, researchers, and policy makers to take responsibility to ensure that these injustices are addressed, and become part of the public discourse about the sources and solutions of endemic social problems. Critique and deconstruction of institutional power in our public, private, and voluntary services is encouraged in a manner that honors diversity and enables sensitive therapy, other forms of service delivery and policy making that genuinely reflect the range of cultural, gender, and socioeconomic experiences of citizens.

    Mesenchymal cells from the prefusion human embryonic palate have been established in culture and can be grown in either a serum-free hormone-supplemented medium or a serum-containing medium. The growth of these cells is quite rapid in culture and inhibited in a dose-dependent manner by most teratogens thus far tested, such as dexamethasone. These cells are highly sensitive to a variety of DNA synthetic and mitotic inhibitors. The responses of these cells are complementary to the ovarian tumor cell attachment assay of Braun et al (1, and in this volume). When used in conjunction with the tumor cells, the overall reliability is greater than 90% with only one false-negative, allopurinol.

    In order for artificial intelligent systems to interact naturally with human users, they need to be able to learn from human instructions when actions should be imitated. Human tutoring will typically consist of action demonstrations accompanied by speech. In the following, the characteristics of human tutoring during action demonstration will be examined. A special focus will be put on the distinction between two kinds of motion events: path-oriented actions and manner-oriented actions. Such a distinction is inspired by the literature pertaining to cognitive linguistics, which indicates that the human conceptual system can distinguish these two distinct types of motion. These two kinds of actions are described in language by more path-oriented or more manner-oriented utterances. In path-oriented utterances, the source, trajectory, or goal is emphasized, whereas in manner-oriented utterances the medium, velocity, or means of motion are highlighted. We examined a video corpus of adult-child interactions comprised of three age groups of children-pre-lexical, early lexical, and lexical-and two different tasks, one emphasizing manner more strongly and one emphasizing path more strongly. We analyzed the language and motion of the caregiver and the gazing behavior of the child to highlight the differences between the tutoring and the acquisition of the manner and path concepts. The results suggest that age is an important factor in the development of these action categories. The analysis of this corpus has also been exploited to develop an intelligent robotic behavior-the tutoring spotter system-able to emulate children's behaviors in a tutoring situation, with the aim of evoking in human subjects a natural and effective behavior in teaching to a robot. The findings related to the development of manner and path concepts have been used to implement new effective feedback strategies in the tutoring spotter system, which should provide improvements in human

    Prior to this study, the sensitivity in nEXO was calculated using an approximate method that does not provide 90% coverage. I find it useful to understand the confidence level of a limit by focusing on the confidence level as a property of the method used to find the limit.A particular method (algorithm,formula) is applied to an experiment to produce a limit. That experiment was conducted in a particular universe with certain values of the physical parameters. We’d like a method than produces a correct limit for 90% of the experiments that could run. We also want that to be true for every universe—that is, regardless of the physical parameter value, the method should still produce a correct limit 90% of the time.

    Death resulting from burns is an important social problem and a frequent accident. However, because approximately 10% of cases are estimated to result from a fire that was deliberately started, all fire-related deaths should be treated as suspicious, and the cause of a fire should be investigated. For the bodies recovered from the scene of a fire, the manner of death could also be suicide or homicide. The objective of this study was to contribute to the clarification of controversial data present in the literature on the manner of death determination of fire-related deaths, through evaluation of autopsy findings of bodies recovered from fires. We reviewed 20,135 autopsies performed in a 5-year period, in Istanbul, as the whole autopsy data of the city and found 133 fire-related deaths. The death scene investigation reports and other judicial documents, autopsy findings, and toxicological analysis results were evaluated to determine the parameters of age, sex, level of the burn, vital signs [red flare; soot in the lower respiratory tract, esophagus, and/or stomach; and screening of carboxyhemoglobin (COHb) levels in the blood], toxicological substances, presence of accelerants, cause of death, and manner of death. The manner of death was determined to be an accident in 98 (73.7%) and homicide in 12 (9%) cases, whereas there was no suicide. In addition, it could not be determined in 23 (17.2%) cases. In accidental deaths, the most frequent cause of death was COHb poisoning with statistically significant blood COHb levels greater than 10%. Further, the presence of soot in the lower respiratory tract, esophagus, and/or stomach and the existence of at least 1 or 2 vital signs together were found to be valid deterministic criteria with statistical significance in terms of identifying the manner of death.

  12. Gluten Sensitivity.

    Non-celiac gluten sensitivity (NCGS) is a syndrome characterized by intestinal and extraintestinal symptoms related to the ingestion of gluten-containing food in subjects who are not affected by either celiac disease (CD) or wheat allergy (WA). The prevalence of NCGS is not clearly defined yet. Indirect evidence suggests that NCGS is slightly more common than CD, the latter affecting around 1% of the general population. NCGS has been mostly described in adults, particularly in females in the age group of 30-50 years; however, pediatric case series have also been reported. Since NCGS may be transient, gluten tolerance needs to be reassessed over time in patients with NCGS. NCGS is characterized by symptoms that usually occur soon after gluten ingestion, disappear with gluten withdrawal, and relapse following gluten challenge within hours/days. The 'classical' presentation of NCGS is a combination of irritable bowel syndrome-like symptoms, including abdominal pain, bloating, bowel habit abnormalities (either diarrhea or constipation), and systemic manifestations such as 'foggy mind', headache, fatigue, joint and muscle pain, leg or arm numbness, dermatitis (eczema or skin rash), depression, and anemia. In recent years, several studies explored the relationship between the ingestion of gluten-containing food and the appearance of neurological and psychiatric disorders/symptoms like ataxia, peripheral neuropathy, schizophrenia, autism, depression, anxiety, and hallucinations (so-called gluten psychosis). The diagnosis of NCGS should be considered in patients with persistent intestinal and/or extraintestinal complaints showing a normal result of the CD and WA serological markers on a gluten-containing diet, usually reporting worsening of symptoms after eating gluten-rich food. NCGS should not be an exclusion diagnosis only. Unfortunately, no biomarker is sensitive and specific enough for diagnostic purposes; therefore, the diagnosis of NCGS is currently based on

  15. Habituation, sensitization and Pavlovian conditioning

    Full Text Available In this brief review, I argue that the impact of a stimulus on behavioral control increase as the distance of the stimulus to the body decreases. Habituation, i.e., decrement in response intensity repetition of the triggering stimulus, is the default state for sensory processing, and the likelihood of habituation is higher for distal stimuli. Sensitization, i.e., increment in response intensity upon stimulus repetition, occurs in a state dependent manner for proximal stimuli that make direct contact with the body. In Pavlovian conditioning paradigms, the US is always a more proximal stimulus than the CS. The mechanisms of associative and non-associative learning are not independent. CS-US pairings lead to formation of associations if sensitizing modulation from a proximal US prevents the habituation for a distal anticipatory CS.

    Culture pervades human lives and has allowed our species to create niches all around the world and its oceans, in ways quite unlike any other primate. Indeed, our cultural nature appears so distinctive that it is often thought to separate humanity from the rest of nature and the Darwinian forces that shape it. A contrary view arises through the recent discoveries of a diverse range of disciplines, here brought together to illustrate the scope of a burgeoning field of cultural evolution and to facilitate cross-disciplinary fertilization. Each approach emphasizes important linkages between culture and evolutionary biology rather than quarantining one from the other. Recent studies reveal that processes important in cultural transmission are more widespread and significant across the animal kingdom than earlier recognized, with important implications for evolutionary theory. Recent archaeological discoveries have pushed back the origins of human culture to much more ancient times than traditionally thought. These developments suggest previously unidentified continuities between animal and human culture. A third new array of discoveries concerns the later diversification of human cultures, where the operations of Darwinian-like processes are identified, in part, through scientific methods borrowed from biology. Finally, surprising discoveries have been made about the imprint of cultural evolution in the predispositions of human minds for cultural transmission.

    The p35 subunit of IL-12 and the Epstein-Barr virus-induced gene 3 (EBI3) have been shown to form a heterodimeric cytokine, named interleukin-35 (IL-35). Recently, mRNA expression of both IL-12p35 and EBI3 was clearly shown in stimulated human T effector cells. Here, we investigated the production of IL-35 protein in human anti-CD3/CD28-stimulated pan T cells as well as T cell subpopulations using a specific human IL-35 ELISA system. We measured high concentrations of IL-35 (up to 3 ng/ml) in cell culture supernatants of stimulated pan T cells as well as CD4(+), CD8(+) and CD4(+)CD25(-) T cell subpopulations at 72 h after stimulation. Very low amounts of IL-35, in the range of 100pg/ml, were detectable in supernatants of resting T cells. These observations could be confirmed using a dot-blot assay for IL-12p35 and EBI3. High concentrations of IL-35 could be also measured in cell culture supernatants of both, resting and stimulated CD4(+)CD25(+) T cells. In order to learn more about the regulation of IL-35 production, we studied the effect of dexamethasone, cyclosporine A and rapamycin on IL-35 production of anti-CD3/CD28-stimulated human pan T cells as well as CD4(+) and CD8(+) T cell subpopulations. All three drugs significantly suppressed IL-35 production of these cells in a proliferation-dependent manner. In summary, we could show that stimulated human peripheral blood T cells of healthy donors produce high amounts of IL-35 protein. However, the biological function of this cytokine remains to be elucidated.

  1. Discoordinate regulation of different K channels in cultured rat skeletal muscle by nerve growth factor.

    We investigated the effects of nerve growth factor (NGF) on expression of K+ channels in cultured skeletal muscle. The channels studied were (1) charybdotoxin (ChTx)-sensitive channels by using a polyclonal antibody raised in rabbits against ChTx, (2) Kv1.5 voltage-sensitive channels, and (3) apamin-sensitive (afterhyperpolarization) channels. Crude homogenates were prepared from cultures made from limb muscles of 1-2-day-old rat pups for identification of ChTx-sensitive and Kv1.5 channels by Western blotting techniques. Apamin-sensitive K+ channels were studied by measurement of specific [125I]-apamin binding by whole cell preparations. ChTx-sensitive channels display a fusion-related increase in expression, and NGF downregulates these channels in both myoblasts and myotubes. Voltage-dependent Kv1.5 channel expression is low in myoblasts and increases dramatically with fusion; NGF induces early expression of these channels and causes expression after fusion to increase even further. NGF downregulates apamin-sensitive channels. NGF increases the rate of fall of the action potential recorded intracellularly from single myotubes with intracellular microelectrodes. The results confirm and extend those of previous studies in showing a functional role for NGF in the regulation of membrane properties of skeletal muscle. Moreover, the findings demonstrate that the different K+ channels in this preparation are regulated in a discoordinate manner. The divergent effects of NGF on expression of different K+ channels, however, do not appear sufficient to explain the NGF-induced increase in the rate of fall of the action potential. The changes during the falling phase may rather be due to increases in channel properties or may result from an increased driving force on the membrane potential secondary to the NGF-induced hyperpolarization.

    Bone mass is determined by the balance between bone formation, carried out by mesenchymal stem cell-derived osteoblasts, and bone resorption, carried out by monocyte-derived osteoclasts. Here we investigated the potential roles of p38 MAPKs, which are activated by growth factors and cytokines including RANKL and BMPs, in osteoclastogenesis and bone resorption by ablating p38α MAPK in LysM+monocytes. p38α deficiency promoted monocyte proliferation but regulated monocyte osteoclastic differentiation in a cell-density dependent manner, with proliferating p38α−/− cultures showing increased differentiation. While young mutant mice showed minor increase in bone mass, 6-month-old mutant mice developed osteoporosis, associated with an increase in osteoclastogenesis and bone resorption and an increase in the pool of monocytes. Moreover, monocyte-specific p38α ablation resulted in a decrease in bone formation and the number of bone marrow mesenchymal stem/stromal cells, likely due to decreased expression of PDGF-AA and BMP2. The expression of PDGF-AA and BMP2 was positively regulated by the p38 MAPK-Creb axis in osteoclasts, with the promoters of PDGF-AA and BMP2 having Creb binding sites. These findings uncovered the molecular mechanisms by which p38α MAPK regulates osteoclastogenesis and coordinates osteoclastogenesis and osteoblastogenesis. PMID:28382965

    The role of tumor-associated macrophages (TAMs) in the development of colon carcinoma is still controversial. Therefore, the present study aimed to investigate the TAM‑driven processes that may affect colon cancer cell proliferation. To achieve this purpose, murine macrophages were co-cultured with C26 murine colon carcinoma cells at a cell density ratio that approximates physiological conditions for colon carcinoma development in vivo. In this respect, the effects of TAM-mediated angiogenesis, inflammation and oxidative stress on the proliferative capacity of C26 murine colon carcinoma cells were studied. To gain insight into the TAM-driven oxidative stress, NADPH oxidase, the main pro-oxidant enzyme in macrophages, was inhibited. Our data revealed that the stimulatory effects of TAMs on C26 cell proliferation may be related mainly to their pro-oxidant actions exerted by NADPH oxidase activity, which maintains the redox status and the angiogenic capacity of the tumor microenvironment. Additionally, the anti-inflammatory and pro-angiogenic effects of TAMs on tumor cells were found to create a favorable microenvironment for C26 colon carcinoma development and progression. In conclusion, our data confirmed the protumor role of TAMs in the development of colon carcinoma in an oxidative stress-dependent manner that potentiates the angiogenic capacity of the tumor microenvironment. These data may offer valuable information for future tumor-targeted therapies based on TAM 're-education' strategies.

  7. The specific surface area of methane hydrate formed in different conditions and manners

    2009-01-01

    The specific surface area of methane hydrates, formed both in the presence and absence of sodium dodecyl sulfate (SDS) and processed in different manners (stirring, compacting, holding the hydrates at the formation conditions for different periods of time, cooling the hydrates for different periods of time before depressurizing them), was measured under atmospheric pressure and temperatures below ice point. It was found that the specific surface area of hydrate increased with the decreasing temperature. The methane hydrate in the presence of SDS was shown to be of bigger specific surface areas than pure methane hydrates. The experimental results further demonstrated that the manners of forming and processing hydrates affected the specific surface area of hydrate samples. Stirring or compacting made the hydrate become finer and led to a bigger specific surface area.

    We have developed a low-cost liver cell culture device that creates fluidic flow over a 3D primary liver cell culture that consists of multiple liver cell types, including hepatocytes and non-parenchymal cells (fibroblasts, stellate cells, and Kupffer cells). We tested the performance of the cell culture under fluidic flow for 14 days, finding that hepatocytes produced albumin and urea at elevated levels compared to static cultures. Hepatocytes also responded with induction of P450 (CYP1A1 and CYP3A4) enzyme activity when challenged with P450 inducers, although we did not find significant differences between static and fluidic cultures. Non-parenchymal cells were similarly responsive, producing interleukin 8 (IL-8) when challenged with 10 μM bacterial lipoprotein (LPS). To create the fluidic flow in an inexpensive manner, we used a rocking platform that tilts the cell culture devices at angles between ±12°, resulting in a periodically changing hydrostatic pressure drop between reservoirs and the accompanying periodically changing fluidic flow (average flow rate of 650 μL min(-1), and a maximum shear stress of 0.64 dyne cm(-2)). The increase in metabolic activity is consistent with the hypothesis that, similar to unidirectional fluidic flow, primary liver cell cultures increase their metabolic activity in response to fluidic flow periodically changes direction. Since fluidic flow that changes direction periodically drastically changes the behavior of other cells types that are shear sensitive, our findings support the theory that the increase in hepatic metabolic activity associated with fluidic flow is either activated by mechanisms other than shear sensing (for example increased opportunities for gas and metabolite exchange), or that it follows a shear sensing mechanism that does not depend on the direction of shear. Our mode of device operation allows us to evaluate drugs under fluidic cell culture conditions and at low device manufacturing and operation

    2009-09-01

    ABSTRACTTwo experiments compared how French vs. English adults and children (three to seven years) described motion events. Given typological properties (Talmy, 2000) and previous results (Choi & Bowerman, 1991; Hickmann, 2003; Slobin, 2003), the main prediction was that Manner should be more salient and therefore more frequently combined with Path (MP) in English than in French, particularly with four types of 'target' events, as compared to manner-oriented 'controls': motion up/down (Experiment I, N=200) and across (Experiment II, N=120), arrivals and departures (both experiments). Results showed that MP-responses (a) varied with events and increased with age in both languages, but (b) were more frequent in English at all ages with all events, and (c) were age- and event-specific among French speakers, who also frequently expressed Path or Manner alone. The discussion highlights several factors accounting for responses, with particular attention to the interplay between cognitive factors that drive language acquisition and typological properties that constrain this process from early on.

    HDM2, a human homologue of MDM2, is a major negative regulator of p53 function, and increased expression of HDM2 by its promoter polymorphism SNP309 resulted in p53 inactivation and an increased risk of several tumours, including neuroblastoma (NB). Herein, we show that increased expression of HDM2 is related to a worse prognosis in MYCN-amplified NB patients. HDM2 plays an important role in the expression of Noxa, a pro-apoptotic molecule of the Bcl-2 family, which induces NB cell apoptotic death after doxorubcin (Doxo) treatment. Knockdown of HDM2 by siRNA resulted in the upregulation of Noxa at mRNA/protein levels and improved the sensitivity of Doxo-resistant NB cells, although these were not observed in p53-mutant NB cells. Noxa-knockdown abolished the recovered Doxo-induced cell death by HDM2 reduction. Intriguingly, resistance to Doxo was up-regulated by over-expression of HDM2 in Doxo-sensitive NB cells. By HDM2 expression, p53 was inactivated but its degradation was not accelerated, suggesting that p53 was degraded in a proteasome-independent manner in NB cells; downstream effectors of p53, p21(Cip1/Waf1) and Noxa were suppressed by HDM2. Noxa transcription was considerably regulated by both p53 and p73 in NB cells. Furthermore, in vivo binding of p53 and p73 to Noxa promoter was suppressed and Noxa promoter activation was inhibited by HDM2. Taken together, our results may indicate that the HDM2-related resistance to chemotherapeutic drugs of NB is regulated by p53/p73-dependent Noxa expression in NB.

    Metformin is a widely used insulin-sensitizing drug, though its mechanisms are not fully understood. Metformin has been shown to activate AMPK in skeletal muscle; however, its effects on the inhibitor of κB kinaseβ (IKKβ) in this same tissue are unknown. The aim of this study was to (1) determine the ability of metformin to attenuate IKKβ action, (2) determine whether changes in AMPK activity are associated with changes in IKKβ action in skeletal muscle, and (3) examine whether changes in AMPK and IKKβ function are consistent with improved insulin signaling. Lean and obese male Zuckers received either vehicle or metformin by oral gavage daily for four weeks (four groups of eight). Proteins were measured in white gastrocnemius (WG), red gastrocnemius (RG), and soleus. AMPK phosphorylation increased (P < .05) in WG in both lean (57%) and obese (106%), and this was supported by an increase in phospho-ACC in WG. Further, metformin increased IκBα levels in both WG (150%) and RG (67%) of obese rats, indicative of reduced IKKβ activity (P < .05), and was associated with reduced IRS1-pSer307 (30%) in the WG of obese rats (P < .02). From these data we conclude that metformin treatment appears to exert an inhibitory influence on skeletal muscle IKKβ activity, as evidenced by elevated IκBα levels and reduced IRS1-Ser307 phosphorylation in a fiber-type specific manner.

Through immunoprecipitation/two-dimensional gel electrophoresis (IP-2DE), MALDI-TOF mass spectrometry, and a pull down assay, we found glutamine synthetase (GS; EC 6.3.1.2) as a candidate interacting protein with Gpx3. GS is a key enzyme in nitrogen metabolism and ammonium assimilation. It has been known that GS is non-enzymatically cleaved by ROS generated by MFO (thiol/ Fe(3+)/O(2) mixed-function oxidase) system. In this study, it is demonstrated that GS interacts with Gpx3 through its catalytic domain both in vivo and in vitro regardless of redox state. In addition, Gpx3 helps to protect GS from inactivation and degradation via oxidative stress in an activity-independent manner. Based on the results, it is suggested that Gpx3 protects GS from non-enzymatic proteolysis, thereby contributing to cell homeostasis when cell is exposed to oxidative stress.

    The concept of organizational culture is here applied to the practice of human resource management. Reasons for the current emphasis on culture as an organizational metaphor are suggested. Cultural indicators which have diagnostic value for human resource professionals include organizational usage of symbols, rituals, ideologies, language, stores, myths, relationships, and humor. Examples of these indicators of culture are drawn from a variety of HRM practices and functions to explore the implications of each indicator. Alternative strategies are presented for improving the management of organizational change through sensitivity to cultural impact and better utilization of existing cultural realities.

    Cultural competence in oncology requires the acquisition of specific knowledge, clinical skills, and attitudes that facilitate effective cross-cultural negotiation in the clinical setting, thus, leading to improved therapeutic outcomes and decreased disparities in cancer care. Cultural competence in oncology entails a basic knowledge of different cultural attitudes and practices of communication of the truth and of decision-making styles throughout the world. Cultural competence always presupposes oncology professionals' awareness of their own cultural beliefs and values. To be able to communicate with cancer patients in culturally sensitive ways, oncologists should have knowledge of the concept of culture in its complexity and of the risks of racism, classism, sexism, ageism, and stereotyping that must be avoided in clinical practice. Oncologists should develop a sense of appreciation for differences in health care values, based on the recognition that no culture can claim hegemony over others and that cultures are evolving under their reciprocal influence on each other. Medical schools and oncology training can teach communication skills and cultural competence, while fostering in all students and young doctors those attitudes of humility, empathy, curiosity, respect, sensitivity, and awareness that are needed to deliver effective and culturally sensitive cancer care.

    Full Text Available Whether managers are concerned with financial issues, marketing, or human resource management (HRM, cultural values and practices do matter. The purpose of this article is to understand Norwegian managers’ cultural values within the cross-cultural landscape of her neighbors in the “Scandinavian cluster.” Clearly, subtle but disturbing differences may surface even when representatives from similar cultures work together. As a follow on from the GLOBE project, data based on the GLOBE instrument were collected on culture and communication values in Norway from 710 Norwegian middle managers for this present study. Although the Scandinavian cultures appear ostensibly similar, the results illustrate that research can reveal subtle but important cultural differences in nations that are similar yet dissimilar. All three Scandinavian societies appear intrinsically egalitarian; they appear to value low Power Distance, directness, and consensus in decision making and to promote Gender Egalitarianism. Nevertheless, there are significant differences in the degrees of commitment to these values by each individual Scandinavian partner. These differences need to be understood and appreciated to avoid misunderstandings.

    Aurora-A is frequently altered in epithelial malignancies. Overexpressing Aurora-A induces centrosome amplification and G2/M cell cycle progression. We have previously shown elevated level of Aurora-A in ovarian cancer and activation of telomerase by Aurora-A in human mammary and ovarian epithelia. Here we report that Aurora-A protects ovarian cancer cells from apoptosis induced by chemotherapeutic agent and activates Akt pathway in a p53-dependent manner. Ectopic expression of Aurora-A renders cells resistant to cisplatin (CDDP), etoposide and paclitaxel-induced apoptosis and stimulates Akt1 and Akt2 activity in wild-type p53 but not p53-null ovarian cancer cells. Aurora-A inhibits cytochrome C release and Bax conformational change induced by CDDP. Knockdown of Aurora-A by RNAi sensitizes cells to CDDP-induced apoptosis and decreases phospho-Akt level in wild-type p53 cells. Reintroduction of p53 decreases Akt1 and Akt2 activation and restores CDDP sensitivity in p53-null but not p53-null-Aurora-A cells. Inhibition of Akt by small molecule inhibitor, API-2, overcomes the effects of Aurora-A-on cell survival and Bax mitochondrial translocation. Taken collectively, these data indicate that Aurora-A activates Akt and induces chemoresistance in a p53-dependent manner and that inhibition of Akt may be an effective means of overcoming Aurora-A-associated chemoresistance in ovarian cancer cells expressing wild-type p53.

    Nonspecific histone deacetylase (HDAC) inhibition has been shown to facilitate the extinction of drug-seeking behavior in a manner resistant to reinstatement. A key open question is which specific HDAC is involved in the extinction of drug-seeking behavior. Using the selective HDAC3 inhibitor RGFP966, we investigated the role of HDAC3 in extinction and found that systemic treatment with RGFP966 facilitates extinction in mice in a manner resistant to reinstatement. We also investigated whether the facilitated extinction is related to the enhancement of extinction consolidation during extinction learning or to negative effects on performance or reconsolidation. These are key distinctions with regard to any compound being used to modulate extinction, because a more rapid decrease in a defined behavior is interpreted as facilitated extinction. Using an innovative combination of behavioral paradigms, we found that a single treatment of RGFP966 enhances extinction of a previously established cocaine-conditioned place preference, while simultaneously enhancing long-term object-location memory within subjects. During extinction consolidation, HDAC3 inhibition promotes a distinct pattern of histone acetylation linked to gene expression within the infralimbic cortex, hippocampus, and nucleus accumbens. Thus, the facilitated extinction of drug-seeking cannot be explained by adverse effects on performance. These results demonstrate that HDAC3 inhibition enhances the memory processes involved in extinction of drug-seeking behavior.

    The tumor suppressor, cylindromatosis (CYLD), is a negative regulator of NF-κB signaling by removing lysine 63-linked ubiquitin chains from multiple NF-κB signaling components, including TRAF2, TRAF6, and NEMO. How CYLD itself is regulated, however, remains yet to be characterized. In this study, we present the first evidence that UV irradiation is able to induce CYLD translocation from the cytoplasm to microtubules and that the cytoskeleton-associated CYLD is subject to posttranslational modification and degradation in a proteasome-independent manner. By immunostaining, we found that CYLD displayed microtubule-like filament localization under ultraviolet (UV) irradiation. Further studies revealed that the cytoskeleton-associated CYLD underwent posttranslational modification, which in turn contributed to CYLD degradation in an unknown manner, distinct from proteasome-mediated degradation under normal conditions. Collectively, our data suggest that UV-induced CYLD degradation might serve as an underlying mechanism for UV-induced NF-κB pathway activation.

    In this study we examine how consonant manner of articulation interacts with intonation type in shaping the F0 contours in English. Native speakers of American English read aloud words differing in vowel length, consonant manner of articulation and consonant position in word. They produced each word in either a statement or question carrier. F0 contours of their speech were extracted by measuring every complete vocal period. Preliminary results based on graphic analysis of three speakers' data suggest that there are three distinct consonantal effects: F0 interruption due to devoicing, a large but brief (10-40 ms) F0 raising at the onset of voicing, and a smaller but longer-lasting F0 raising throughout a large proportion of the preceding and following vowels. These effects appear to be imposed on a continuously changing F0 curve that is either rising-falling or falling-rising, depending on whether the carrier sentence is a statement or a question. Further analysis will test the hypothesis that these continuous curves result from local pitch targets that are assigned to individual syllables and implemented with them in synchrony regardless of their segmental composition.

    Niobium suboxide powder was pressed and sintered in vacuum into NbO electrolytic capacitor sintered anode..High voltage and constant current formation experiment was performed on NbO electrolytic capacitor anode,during which electrolyte was 0.01 % Ha PO4 solution, temperature was 90 C and current was 50 mA per gram sample. Through the relationship between anode voltage and time and scanning electron microscopy(SEM) images of invalidated anode and normal forming anode, invalidation manner and mechanism of NbO electrolytic capacitor anode were discussed. The results show that, the main invalidation manner of NbO electrolytic capacitor anode is not short circuit but open circuit, which is different to that of traditional Ta electrolytic capacitor anode. The reason of invalidation is that anode oxide film whose thickness increases gradually penetrates the "connection neck" among anode powder particles, which leads to the open circuit invalidation of anode. Compared with Ta electrolytic capacitor,NbO electrolytic capacitor has better security.

This study in respect of purpose is applied and in terms of collecting data is a descriptive survey research. The research statistic population consists of all managers and experts of the agricultural organizations of Kerman province that based on Cochran formula 300 people were randomly selected for the infinite population. A questionnaire was used for the data collection. Data analysis via method of path analysis was performed with SPSS version 19. Results of the path analysis showed that in the administrations under investigation the attention to the motivation and hygienic issues has been faded in the work environment; while in the above administrations to the task-orientedness has been paid more attention by managers than to relationship-orientedness. Therefore it is appropriate that through correct and timely dissemination of information and training managers and organizational staff to use the appropriate leadership styles according to the requirement of organizational and administrative conditions their productivity is increased.

    Transcription activator-like effectors (TALEs) are a class of transcription factors that are readily programmable to regulate gene expression. Despite their growing popularity, little is known about binding site parameters that influence TALE-mediated gene activation in mammalian cells. We demonstrate that TALE activators modulate gene expression in mammalian cells in a position- and strand-dependent manner. To study the effects of binding site location, we engineered TALEs customized to recognize specific DNA sequences located in either the promoter or the transcribed region of reporter genes. We found that TALE activators robustly activated reporter genes when their binding sites were located within the promoter region. In contrast, TALE activators inhibited the expression of reporter genes when their binding sites were located on the sense strand of the transcribed region. Notably, this repression was independent of the effector domain utilized, suggesting a simple blockage mechanism. We conclude that TALE activators in mammalian cells regulate genes in a position- and strand-dependent manner that is substantially different from gene activation by native TALEs in plants. These findings have implications for optimizing the design of custom TALEs for genetic manipulation in mammalian cells.

    Mitochondrial dysfunction may be a long-term consequence of a poor nutritional environment during early life. Our aim was to investigate whether a maternal low-protein (LP) diet may program mitochondrial dysfunction in islets of adult progeny before glucose intolerance ensues. To address this, pregnant Wistar rats were fed isocaloric diets containing either 20% protein (control) or 8% protein (LP diet) throughout gestation. From birth, offspring received the control diet. The mitochondrial function was analyzed in islets of 3-mo-old offspring. Related to their basal insulin release, cultured islets from both male and female LP offspring presented a lower response to glucose challenge and a blunted ATP production compared with control offspring. The expression of malate dehydrogenase as well as the subunit 6 of the ATP synthase encoded by mitochondrial genome (mtDNA) was lower in these islets, reducing the capacity of ATP production through the Krebs cycle and oxidative phosphorylation. However, mtDNA content was unchanged in LP islets compared with control. Several consequences of protein restriction during fetal life were more marked in male offspring. Only LP males showed an increased reactive oxygen species production associated with a higher expression of mitochondrial subunits of the electron transport chain NADH-ubiquinone oxireductase subunit 4L, an overexpression of peroxisome proliferator-activated receptor-gamma and uncoupling protein-2, and a strongly reduced beta-cell mass. In conclusion, mitochondrial function is clearly altered in islets from LP adult offspring in a sex-specific manner. That may provide a cellular explanation for the earlier development of glucose intolerance in male than in female offspring of dams fed an LP diet.

    Is there a relationship between decidualization and apoptosis of decidual stromal cells (DSC)? Decidualization triggers the secretion of soluble factors that induce apoptosis in DSC. The differentiation and apoptosis of DSC during decidualization of the receptive decidua are crucial processes for the controlled invasion of trophoblasts in normal pregnancy. Most DSC regress in a time-dependent manner, and their removal is important to provide space for the embryo to grow. However, the mechanism that controls DSC death is poorly understood. The apoptotic response of DSC was analyzed after exposure to different exogenous agents and during decidualization. The apoptotic potential of decidualized DSC supernatants and prolactin (PRL) was also evaluated. DSC lines were established from samples of decidua from first trimester pregnancies. Apoptosis was assayed by flow cytometry. PRL production, as a marker of decidualization, was determined by enzyme-linked immunosorbent assay. DSCs were resistant to a variety of apoptosis-inducing substances. Nevertheless, DSC underwent apoptosis during decidualization in culture, with cAMP being essential for both apoptosis and differentiation. In addition, culture supernatants from decidualized DSC induced apoptosis in undifferentiated DSC, although paradoxically these supernatants decreased the spontaneous apoptosis of decidual lymphocytes. Exogenously added PRL did not induce apoptosis in DSC and an antibody that neutralized the PRL receptor did not decrease the apoptosis induced by supernatants. Further studies are needed to examine the involvement of other soluble factors secreted by decidualized DSC in the induction of apoptosis. The present results indicate that apoptosis of DSC occurs in parallel to differentiation, in response to decidualization signals, with soluble factors secreted by decidualized DSC being responsible for triggering cell death. These studies are relevant in the understanding of how the regression of decidua

    This paper explores the relationship between the structure and culture of an organization. The starting assumption is that organizational structure and organizational culture impact each other, and that there is a causal relationship due to which the agreement of the two components of organization leads to better performance. First, the mechanism through which organizational culture impacts the design of organizational structures and the manner in which org...

    Full Text Available Abstract Background 25-hydroxycholesterol (25-OHC is a product of oxidation of dietary cholesterol present in human plasma. 25-OHC and other oxidized forms of cholesterol are implicated in modulating inflammatory responses involved in development of atherosclerosis and colon carcinogenesis. Methods Primary lymphatic, venous and arterial endothelial cells isolated from bovine mesentery (bmLEC, bmVEC, bmAEC were treated with 25-OHC and tested for several different cellular parameters. Results We found 25-OHC to be a potent inducer of cyclooxygenase-2 (Cox-2, prostaglandin G-H synthase-2 expression in bovine mesenteric lymphatic, venous, and arterial endothelial cells. The induction of Cox-2 expression in endothelial cells by 25-OHC led to an initial increase in cellular proliferation that was inhibited by the Cox-2 selective inhibitor celecoxib (Celebrex. Prolonged exposure to 25-OHC was cytotoxic. Furthermore, endothelial cells induced to express Cox-2 by 25-OHC were more sensitive to the effects of the Cox-2 selective inhibitor celecoxib (Celebrex. These results suggest that some effects of 25-OHC on cells may be dependent on Cox-2 enzymatic activity. Conclusions Cox-2 dependent elevating effects of 25-OHC on endothelial cell proliferation was transient. Prolonged exposure to 25-OHC caused cell death and enhanced celecoxib-induced cell death in a cell-type dependent manner. The lack of uniform response by the three endothelial cell types examined suggests that our model system of primary cultures of bmLECs, bmVECs, and bmAECs may aid the evaluation of celecoxib in inhibiting proliferation of different types of tumour-associated endothelial cells.

  14. Human Rights and Cultural Identity

    Full Text Available Universal human rights and particular cultural identities, which are relativistic by nature, seem to stand in conflict with each other. It is commonly suggested that the relativistic natures of cultural identities undermine universal human rights and that human rights might compromise particular cultural identities in a globalised world. This article examines this supposed clash and suggests that it is possible to frame a human rights approach in such a way that it becomes the starting point and constraining framework for all non-deficient cultural identities. In other words, it is possible to depict human rights in a culturally sensitive way so that universal human rights can meet the demands of a moderate version of meta-ethical relativism which acknowledges a small universal core of objectively true or false moral statements and avers that, beyond that small core, all other moral statements are neither objectively true nor false.

    Aim: To examine the insulin sensitizing effects of a novel α-methyl-α-phenoxylpropionate derivative YY20 in insulin-sensitive cell lines. Methods: The peroxisome proliferator-activated receptorγ(PPARγ) agonist bioactivities of YY20 were detected by a preadipocyte differentiation assay. RT-PCR and Western blotting analysis were used to detect the expression of the target gene or protein.The effects of YY20 on insulin-mediated glucose consumption were determined in the HepG2 human hepatocellular carcinoma line. Results: YY20 could enhance the differentiation of preadipocytes to adipocytes and upregulate the gene ex-pression of PPAR),2, as well as the protein expression of insulin receptor sub-strate-1 (IRS-1), glucose transporter-4 (GLUT4), and adiponectin (ACRP30). The effects on GLUT4 and ACRP30 could be reversed by the PPARγinhibitor SR-202.Furthermore, YY20 efficiently reduced glucose consumptions in HepG2 cells after 24 h culture, and the effects were related to insulin and YY20 concentrations.Conclusion: YY20, a potential insulin-sensitizing agent like rosiglitazone, could enhance glucose consumption in HepG2 cells in a concentration- and insulin-dependent manner. It may improve the insulin resistance associated with type 2 diabetes.

  17. Cultural tourism and tourism cultures

    Ooi, Can-Seng

    Presenting a comprehensive and dynamic understanding of cultural tourism, this volume examines cultural mediators and how they help tourists appreciate foreign cultures. It also shows how tourism experiences are strategically crafted by mediators, the complexity of the mediation process, and how...... various products are mediated differently. A number of different products are investigated, including destination brand identities, "living" cultures and everyday life, art and history. The author illustrates his arguments by comparing the tourism strategies of Copenhagen and Singapore, and demonstrates...... how tourism is an agent for social change. The author also offers an original and refreshing way of understanding tourist behaviour through the concept of the "versatile tourist". The book's empirical cases and dialogic framework provide new and deep insights into tourism activities. In his...

    Chinese cuisine is the main reflection of our country’s cuisine culture. It contains profound historical and cultural background. Besides, it permeates folk-custom taste and local manners. Since the name of a cuisine is the first impression given to a dining person, undoubtedly, its translation is very important in cultural dissemination and communication. But actually, there are many problems exist in Chinese cuisine translation at present. This paper is based on a massive collection of Chinese cuisine ’s translation, classification, analysis. Besides, it has found out cultural connotation, current situation and the causes from the cultural angle;discussed the basic requirements of translating Chinese cuisine.

    Suchomel, TJ, Sato, K, DeWeese, BH, Ebben, WP, and Stone, MH. Potentiation effects of half-squats performed in a ballistic or nonballistic manner. J Strength Cond Res 30(6): 1652-1660, 2016-This study examined and compared the acute effects of ballistic and nonballistic concentric-only half-squats (COHSs) on squat jump performance. Fifteen resistance-trained men performed a squat jump 2 minutes after a control protocol or 2 COHSs at 90% of their 1 repetition maximum (1RM) COHS performed in a ballistic or nonballistic manner. Jump height (JH), peak power (PP), and allometrically scaled peak power (PPa) were compared using three 3 × 2 repeated-measures analyses of variance. Statistically significant condition × time interaction effects existed for JH (p = 0.037), PP (p = 0.041), and PPa (p = 0.031). Post hoc analysis revealed that the ballistic condition produced statistically greater JH (p = 0.017 and p = 0.036), PP (p = 0.031 and p = 0.026), and PPa (p = 0.024 and p = 0.023) than the control and nonballistic conditions, respectively. Small effect sizes for JH, PP, and PPa existed during the ballistic condition (d = 0.28-0.44), whereas trivial effect sizes existed during the control (d = 0.0-0.18) and nonballistic (d = 0.0-0.17) conditions. Large statistically significant relationships existed between the JH potentiation response and the subject's relative back squat 1RM (r = 0.520; p = 0.047) and relative COHS 1RM (r = 0.569; p = 0.027) during the ballistic condition. In addition, large statistically significant relationship existed between JH potentiation response and the subject's relative back squat strength (r = 0.633; p = 0.011), whereas the moderate relationship with the subject's relative COHS strength trended toward significance (r = 0.483; p = 0.068). Ballistic COHS produced superior potentiation effects compared with COHS performed in a nonballistic manner. Relative strength may contribute to the elicited potentiation response after ballistic and
