Green Tea Attenuates Benzene-Induced Oxidative Stress in Pump Workers

Workers exposed to benzene frequently suffer from toxicities of the bone marrow as well as the central nervous, immune, and reproductive systems. This toxicity most likely is a result of the oxidative metabolism of benzene to reactive products. As green tea possesses antioxidant effects, the objective of this study was to examine any amelioration of benzene-induced oxidative stress in pump workers drinking 6 cups (150 ml/cup) of freshly prepared tea daily. Sixty male non-smoking subjects, divided into four groups: no benzene exposure/no green tea; no exposure/tea; exposure/no tea; and, exposure/tea, were monitored after a 6 mo period. On the final day of the study, urine samples were collected for analyses of benzene, trans-trans muconic acid, and phenol. Blood was also collected at this time; plasma was assayed for total antioxidant activity, malondialdehyde (MDA), and glutathione (GSH) while erythrocytes were analyzed for activity of antioxidant enzymes glutathione peroxidase (GSHPX), superoxide dismutase (SOD), and catalase. The results demonstrated that urinary levels of benzene, trans-trans muconic acid, and phenol were elevated in all pump workers, and that this elevation was mitigated by consumption of green tea. The benzene exposures also led to significant reductions in plasma GSH levels and erythrocyte antioxidant enzyme activities; these effects were abrogated (to near-control levels) by the tea. Interestingly, among control subjects, tea ingestion itself caused significant increases in both GSHPX and catalase activities. Unlike with the other plasma parameters, while the benzene exposures also significantly increased plasma MDA levels and decreased total antioxidant activity, tea ingestion did not cause a near-total reversion to control values; the effects on these two endpoints were more like those noted with the urine parameters (mitigation, not abrogation). These studies demonstrate that drinking green tea during benzene exposure can reduce several parameters indicative of oxidative stress. As such, as a dietary supplement, green tea could represent a potential therapeutic agent in reducing certain aspects of benzene-induced toxicity.
Apple peels as a value-added food ingredient.

There is some evidence that chronic diseases, such as cancer and cardiovascular disease, may occur as a result of oxidative stress. Apple peels have high concentrations of phenolic compounds and may assist in the prevention of chronic diseases. Millions of pounds of waste apple peels are generated in the production of applesauce and canned apples in New York State each year. We proposed that a valuable food ingredient could be made using the peels of these apples if they could be dried and ground to a powder without large losses of phytochemicals. Rome Beauty apple peels were treated with citric acid dips, ascorbic acid dips, and blanches before being oven-dried at 60 degrees C. Only blanching treatments greatly preserved the phenolic compounds, and peels blanched for 10 s had the highest total phenolic content. Rome Beauty apple peels were then blanched for 10 s and dried under various conditions (oven-dried at 40, 60, or 80 degrees C, air-dried, or freeze-dried). The air-dried and freeze-dried apple peels had the highest total phenolic, flavonoid, and anthocyanin contents. On a fresh weight basis, the total phenolic and flavonoid contents of these samples were similar to those of the fresh apple peels. Freeze-dried peels had a lower water activity than air-dried peels on a fresh weight basis. The optimal processing conditions for the ingredient were blanching for 10s and freeze-drying. The process was scaled up, and the apple peel powder ingredient was characterized. The total phenolic content was 3342 +/- 12 mg gallic acid equivalents/100 g dried peels, the flavonoid content was 2299 +/- 52 mg catechin equivalents/100 g dried peels, and the anthocyanin content was 169.7 +/- 1.6 mg cyanidin 3-glucoside equivalents/100 g dried peels. These phytochemical contents were a significantly higher than those of the fresh apple peels if calculated on a fresh weight basis (p < 0.05). The apple peel powder had a total antioxidant activity of 1251 +/- 56 micromol vitamin C equivalents/g, similar to fresh Rome Beauty peels on a fresh weight basis (p > 0.05). One gram of powder had an antioxidant activity equivalent to 220 mg of vitamin C. The freeze-dried apple peels also had a strong antiproliferative effect on HepG(2) liver cancer cells with a median effective dose (EC(50)) of 1.88 +/- 0.01 mg/mL. This was lower than the EC(50) exhibited by the fresh apple peels (p < 0.05). Apple peel powder may be used in a various food products to add phytochemicals and promote good health.
Avionic technology testing by using a cognitive neurometric index: A study with professional helicopter pilots

In this study, we investigated the possibility to evaluate the impact of different avionic technologies on the mental workload of helicopter's pilots by measuring their brain activity with the EEG during a series of simulated missions carried out at AgustaWestland facilities in Yeovil (UK). The tested avionic technologies were: i) Head-Up Display (HUD); ii) Head-Mounted Display (HMD); iii) Full Conformal symbology (FC); iv) Flight Guidance (FG) symbology; v) Synthetic Vision System (SVS); and vi) Radar Obstacles (RO) detection system. It has been already demonstrated that in cognitive tasks, when the cerebral workload increases the EEG power spectral density (PSD) in theta band over frontal areas increases, and the EEG PSD in alpha band decreases over parietal areas. A mental workload index (MWL) has been here defined as the ratio between the frontal theta and parietal alpha EEG PSD values. Such index has been used for testing and comparing the different avionic technologies. Results suggested that the HUD provided a significant (p<;.05) workload reduction across all the flight scenarios with respect to the other technologies. In addition, the simultaneous use of FC and FG technologies (FC+FG) produced a significant decrement of the workload (p<;.01) with respect to the use of only the FC. Moreover, the use of the SVS technology provided on Head Down Display (HDD) with the simultaneous use of FC+FG and the RO seemed to produce a lower cerebral workload when compared with the use of only the FC. Interestingly, the workload estimation by means of subjective measures, provided by pilots through a NASA-TLX questionnaire, did not provide any significant differences among the different flight scenarios. These results suggested that the proposed MWL cognitive neurometrics could be used as a reliable measure of the user's mental workload, being a valid indicator for the comparison and the test of different avionic technologies.
[Phlebotomus from Madagascar (Diptera: Psychodidae). II--Description of the female Phlebotomus (Anaphlebotomus) fertei Depaquit, Léger & Robert, 2002; description of the male and new data for the female Phlebotomus (Anaphlebotomus) berentiensis (Léger & Rodhain, 1978) comb. nov].

The female of Phlebotomus (Anaphlebotomus) fertei Depaquit, Leger & Robert, 2002 is described from Madagascar. The spermathecae have separated ducts, a body with an enlarged-sclerified dilatation and a deriviated large bladder with thin walls and long head. P. fertei female has the following characters: long antennal segments, pharyngeal armature with small teeth and cibarium with 15 to 30 denticles, and very long legs. Its remarkable spermatheca is closely related to that of P. berentiensis. The status of P. (Anaphlebotomus) berentiensis (Leger & Rodhain, 1978) is revised into this paper. The female is redescribed and the male is described for the first time. The latter has an unusual antennal formula (2/III-XII), a cibarium with four teeth and about 30 denticles, no tuft of setae on the coxite, four spines on the style, including a very long proximal one. Males and females were linked to each other based on morphological and molecular characteristics (second internal transcribed spacer of the ribosomal DNA and ND4 gene of the mitochondrial DNA). The inclusion of these taxa into the subgenus Anaphlebotomus Theodor, 1948 is exclusively based on male characters as listed by Theodor (style with four spines, no basal lobe on the coxite, paramere with two or three branches). The very heterogeneous characters of the females do not allow their use for the definition of this subgenus, which is probably not homogeneous.
How economic crises affect political representation: declining party‒voter congruence in times of constrained government

Abstract How do economic crises affect political representation in times of constrained government? Our paper shows that among voters salience of economic issues increases during economically harsh times. However, parties respond only to a limited degree to economic shocks, with the result that congruence between parties and voters decreases. We theorise the incentives and disincentives different political parties have in choosing a saliency strategy and we provide evidence on the extent to which congruence depends on the severity of economic shocks and the government/opposition status of the party. We draw on cross-national data to measure issue salience for parties (CMP) and voters (CSES). While our findings clearly indicate a decline of congruence in times of economic crisis, we also find that it remains best for government and office-seeking opposition parties. We substantiate this finding by unpacking the ways in which incumbent and office-seeking opposition parties address the economy in their manifestos.
Three-dimensional holographic photostimulation of the dendritic arbor

Digital holography is an emerging technology that can generate complex light patterns for controlling the excitability of neurons and neural circuits. The strengths of this technique include a high efficiency with which available light can be effectively utilized and the ability to deliver highly focused light to multiple locations simultaneously. Here we demonstrate another strength of digital holography: the ability to generate instantaneous three-dimensional light patterns. This capability is demonstrated with the photolysis of caged glutamate on the dendritic arbor of hippocampal neurons, to study the nature of the integration of inputs arriving on multiple dendritic branches.
Susceptibility Patterns and Molecular Identification of Trichosporon Species

ABSTRACT The physiological patterns, the sequence polymorphisms of the internal transcriber spacer (ITS), and intergenic spacer regions (IGS) of the rRNA genes and the antifungal susceptibility profile were evaluated for their ability to identify Trichosporon spp. and their specificity for the identification of 49 clinical isolates of Trichosporon spp. Morphological and biochemical methodologies were unable to differentiate among the Trichosporon species. ITS sequencing was also unable to differentiate several species. However, IGS1 sequencing unambiguously identified all Trichosporon isolates. Following the results of DNA-based identification, Trichosporon asahii was the species most frequently isolated from deep sites (15 of 25 strains; 60%). In the main, other Trichosporon species were recovered from cutaneous samples. The majority of T. asahii, T. faecale, and T. coremiiforme clinical isolates exhibited resistance in vitro to amphotericin B, with geometric mean (GM) MICs >4 μg/ml. The other species of Trichosporon did not show high MICs of amphotericin B, and GM MICs were <1 μg/ml. Azole agents were active in vitro against the majority of clinical strains. The most potent compound in vitro was voriconazole, with a GM MIC ≤0.14 μg/ml. The sequencing of IGS correctly identified Trichosporon isolates; however, this technique is not available in many clinical laboratories, and strains should be dispatched to reference centers where these complex methods are available. Therefore, it seems to be more practical to perform antifungal susceptibility testing of all isolates belonging to Trichosporon spp. , since correct identification could take several weeks, delaying the indication of an antifungal agent which exhibits activity against the infectious strain.
The Role of Adherence in Virological Suppression in Patients Receiving Anti-HBV Analogues

Background Although adherence is of major importance in long-term treatments, few studies have been published regarding the use of anti-HBV analogues in clinical practice. The aim of this study was to evaluate adherence to anti-HBV analogues and associated virological suppression. Methods A cross-sectional study was performed between 1 January 2009 and 15 July 2009 in Cochin Hospital, Paris, France. It included all patients being treated with anti-HBV analogues for at least three months, who were without coinfection (HIV, HCV or HDV) and who had not received organ transplants. At the time of enrolment, HBV viral load, analogue regimen and self-reported adherence were collected prospectively. Patients were classified as non-adherent, or moderately or totally adherent using a score based on analysis of self-reports. Other data were obtained retrospectively. Results Among the 190 patients meeting the inclusion criteria, 33% were initially hepatitis B e antigen-positive and 50% had extensive fibrosis or cirrhosis. Pretreatment viral load was 6.0 log IU/ml (median). The median duration of treatment was 52 months. At enrolment, 61%, 32% and 7% of patients were classified as totally adherent, moderately adherent and non-adherent, respectively. Complete virological suppression (HBV DNA<12 IU/ml) was observed in 83% of patients at enrolment. In the multivariate analysis, lack of virological suppression was associated with an increased pretreatment viral load, with no change in analogue regimen and is classified as non-adherent. Conclusions Adherence seems to be an independent factor associated with virological suppression during anti-HBV analogue treatment. Therapeutic education and a systematic evaluation of adherence using self-reports should be promoted to assure long-term anti-HBV analogue efficacy in clinical practice.
Altered Tumor Biology and Tumorigenesis in Irradiated and Chemical Carcinogen-Treated Single and Combined Connexin32/p27Kip1-Deficient Mice

Connexin32 knockout mice (Cx32-KO) exhibit increased chemical and radiation-induced liver and lung tumorigenesis. This increased tumor incidence is associated with altered tumor biology including enhanced tumor progression and an increased percent of MAPK-active tumors. Likewise, mice lacking the tumor suppressor/cell cycle regulator p27Kip1 exhibit increased tumorigenesis in a variety of tissues following chemical and radiation induction. Interestingly, in a double-deficient mouse model (DKO), additional loss of p27Kip1 in a Cx32-KO background results in attenuation of liver and lung tumorigenesis as well as MAPK activation profiles, suggesting pathway interaction. While these mouse strains exhibit altered liver and lung tumor susceptibility following both chemical (DEN) and radiation (X-ray) induction protocols, comparisons of the resulting tumor incidence, multiplicity, tumor progression, and MAPK activation in response to these two distinct carcinogens underscores the separate influence of each individual gene on both tumor formation and activation of specific oncogenic pathways. Furthermore, these studies demonstrate that different carcinogens interact disparately with Cx32/p27Kip1 genotypic backgrounds in situ resulting in varied tumorigenic response.
Low suspicion lesions on multiparametric magnetic resonance imaging predict for the absence of high‐risk prostate cancer

Study Type – Diagnostic (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Over‐treatment of indolent prostate cancer lesions is a problem which can result in increased human and medical costs. Lesions with a low suspician level at mpMRI of the prostate have low risk of including high risk prostate cancer.
Preparing Teachers To Partner With Families

Decades of research have demonstrated that family involvement significantly contributes to improved student outcomes relating to learning and overall school success. Teachers must be prepared to promote effective family involvement in the education of all children including those students with disabilities. Many factors can be attributed to successful outcomes for a student with a disability both in the school and the broader community. Families of children with disabilities can be one of these significant factors, yet teachers and those who prepare teachers are often ill prepared and lack essential skills and basic knowledge about the process of partnering with families of children with disabilities. The present study attempted to build on what we already know about family involvement and teacher preparation. The research was situated within an urban metropolitan university college of education. This study sought to determine the effectiveness of a content related module on the knowledge and disposition of pre-service teachers. The module contained content centered on the areas of family involvement, partnerships, and assumptions about families. The study included two dependant variables: level of knowledge and disposition. The independent variable was the experimental treatment, an online instructional module. The module was conceptualized as an instructional tool to expose participants, students preparing to be teachers, to the
Cyanidin-3-O-β-glucoside improves obesity and triglyceride metabolism in KK-Ay mice by regulating lipoprotein lipase activity.

BACKGROUND Cyanidin-3-O-β-glucoside (Cy-3-g)-rich foods have been reported to inhibit the onset of obesity, but whether the pure anthocyanin supplementation affects obesity remains uncertain. RESULTS Cy-3-g supplementation significantly reduced obesity, accumulation of fat in visceral adipose and liver tissues, and plasma triglyceride levels. Furthermore, adenosine monophosphate (AMP)-activated protein kinase phosphorylation (pAMPK) in the skeletal muscle and visceral adipose were significantly increased by Cy-3-g consumption. This was followed by the activation of lipoprotein lipase (LPL) in plasma and skeletal muscle but the suppression of this enzyme in visceral adipose. LPL activation in skeletal muscle cells and its suppression in adipocytes by Cy-3-g were blocked by inhibition of pAMPK. CONCLUSION Our present data thus demonstrate that Cy-3-g improves obesity and triglyceride metabolism in KK-Ay mice. The underlying mechanism is found to be partly related to the activation of LPL in plasma and skeletal muscle, and inhibition of LPL in adipose tissue following the activation of pAMPK.
Dualized trust: risk, social trust and the welfare state

This article examines how labour market vulnerability and social policy interact to shape generalized trust. Drawing insights from the literature on dualization, I suggest that: (1) labour market outsiders will have lower levels of generalized trust due to their increased risk exposure; and (2) active labour market policies, by conditioning labour market vulnerability, can reduce the impact of outsiderness on trust. Leveraging within-country cleavages between insiders and outsiders therefore allows us to assess one possible mechanism behind the welfare state’s generation of trust, while at the same time holding cultural context and broader trust levels constant. Analysis of data from the 2008–2014 waves of the European Social Survey then provides evidence of the impact of outsiderness on trust and the ability of social policy to moderate that effect. The investigation thus sheds light on both an additional consequence of dualization and a mechanism linking the welfare state to generalized trust.
Trehalose 6-Phosphate Is Required for the Onset of Leaf Senescence Associated with High Carbon Availability1[W][OA]

Trehalose 6-phosphate (T6P) is an important regulator of plant metabolism and development. T6P content increases when carbon availability is high, and in young growing tissue, T6P inhibits the activity of Snf1-related protein kinase (SnRK1). Here, strong accumulation of T6P was found in senescing leaves of Arabidopsis (Arabidopsis thaliana), in parallel with a rise in sugar contents. To determine the role of T6P in senescence, T6P content was altered by expressing the bacterial T6P synthase gene, otsA (to increase T6P), or the T6P phosphatase gene, otsB (to decrease T6P). In otsB-expressing plants, T6P accumulated less strongly during senescence than in wild-type plants, while otsA-expressing plants contained more T6P throughout. Mature otsB-expressing plants showed a similar phenotype as described for plants overexpressing the SnRK1 gene, KIN10, including reduced anthocyanin accumulation and delayed senescence. This was confirmed by quantitative reverse transcription-polymerase chain reaction analysis of senescence-associated genes and genes involved in anthocyanin synthesis. To analyze if the senescence phenotype was due to decreased sugar sensitivity, the response to sugars was determined. In combination with low nitrogen supply, metabolizable sugars (glucose, fructose, or sucrose) induced senescence in wild-type and otsA-expressing plants but to a smaller extent in otsB-expressing plants. The sugar analog 3-O-methyl glucose, on the other hand, did not induce senescence in any of the lines. Transfer of plants to and from glucose-containing medium suggested that glucose determines senescence during late development but that the effects of T6P on senescence are established by the sugar response of young plants.
REFLECTING WITH TEACHERS WHO WERE HIGHLY SUPPORTED IN THEIR FIRST YEARS OF TEACHING: WHAT STRATEGIES HELPED THEM REMAIN IN THE PROFESSION

Success and satisfaction in the teaching profession are goals; teacher turnover and burnout being constant problems. This study explored factors of support to determine why teachers remain in teaching. Sixty teachers took part in a federal grant, the AIMS (autism, inclusion, math, science) Scholar Program, designed to provide transitional support for newly hired teachers. The participants were queried in order to ascertain sufficient data to identify the salient triggers of pre-attrition related casual agents. The grant was tailored for teachers completing university teaching programs. Enrolled students were from all areas of California, with most being in the southern part of the state. One hundred percent of the participants were still teaching at the time of the research. This dissertation was designed to discern how support early in their careers enabled these teachers to thrive. Open-ended survey questions and in-depth interviews provided insight into why these teachers stayed in the profession and have plans to continue to teach for many years to come. Classroom observations yielded data to support their effectiveness in the classroom. This study was primarily based on teacher perceptions of teacher professional competence and their own performance in the classroom. There is a need to determine the relationship between teacher professional competence as measured by student achievement, student self-esteem, and parent perceptions of teacher competence as they relate to attrition. Six themes were determined as support strategies that helped this group of teachers remain in teaching. It is suggested that these 6 themes be integrated into all support programs to ensure
