Alteration in estrous cycle, lipid peroxidation and antioxidant status in female rat after exposure to lambda cyhalothrin and its attenuation by taurine

Lambda cyhalothrin, a broad spectrum pyrethroid, is being extensively used against a wide range of pests in agricultural practices. The present study was highlighted to investigate the effects of the lambda cyhalothrin on estrous cycle and oxidative stress in rat ovary, also to find out the protective role of taurine against lambda cyhalothrin induced ovarian toxicity. Mature 36 female Wistar rats were divided in six groups and they were received oral administration of lambda cyhalothrin at two dose levels (8.33 and 16.66 mg/kg body wt) for consecutive14 days. Taurine (50mg/kg body wt) was treated before lambda cyhalothrin administration in the combined taurine-lambda cyhalothrin treated groups. Lambda cyhalothrin caused significant alterations in estrous cycle with an increase in diestrous index compared to control rats. Lambda cyhalothrin treatment also produced oxidative stress in ovary by significant increase in malondialdehyde level, accompanied by a reduction in reduced glutathione and antioxidant enzymes (superoxide dismutase, catalase, glutathione-s-transferase, glutathione peroxidase, glutathione reductase). The present study revealed that the pretreatment of taurine was able to ameliorate lambda cyhalothrin induced ovarian oxidative stress.
Ovicidal Activity and Biological Effects of Radiant and Hexaflumuron Against Eggs of Pink Bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae)

Under the laboratory conditions, toxicological evaluation of two compounds, Radiant SC 12% and Hexaflumuron (IGR) EC 10% against eggs of Pectinophora gossypiella (Saund.) and biological effect of these compounds on larvae, pupae and adult emergence resulted from treated eggs was also studied. The results revealed that LC 50s were 3.15, 0.811and 0.522 ppm. , when one, two and prehatching days old eggs, respectively were treated with Radiant, while LC50s were 3.754, 2.863 and 2.004 ppm, respectively for Hexaflumuron. The obtained results show a prolongation in larval and pupal developments resulted from treated eggs by Radiant, estimated by 20.8, 18.5 and 8.2 days, respectively for larvae and 8.9, 8.8 and 7.9 days for pupae. In case of Hexaflumuron, duration were 22.3, 20.6 and 20.4 days, respectively for larvae after egg treated and 10.8,10.0 and 11.3 days, respectively for pupae. In contrast, in adult stage, the results indicated high reduction in total eggs laid, percentage of hatchability and longevity.
TRANSPORT OF THE FIRST ROCKS OF THE SOLAR SYSTEM BY X-WINDS

It has been suggested that chondrules and calcium–aluminum-rich inclusions (CAIs) were formed at the inner edge of the protoplanetary disk and then entrained in magnetocentrifugal X-winds. We study trajectories of such solid bodies with the consideration of the central star gravity, the protoplanetary disk gravity, and the gas drag of the wind. The efficiency of the gas drag depends on a parameter η, which is the product of the solid body size and density. We find that the gravity of the protoplanetary disk has a non-negligible effect on the trajectories. If a solid body re-enters the flared disk, the re-entering radius depends on the stellar magnetic dipole moment, the disk's gravity, the parameter η, and the initial launching angle. The disk's gravity can make the re-entering radius lower by up to 30%. We find a threshold η, denoted as ηt, for any particular configuration of the X-wind, below which the solid bodies will be expelled from the planetary system. ηt sensitively depends on the initial launching angle, and also depends on the mass of the disk. Only the solid bodies with an η larger than but very close to ηt can be launched to a re-entering radius larger than 1 AU. This size-sorting effect may explain why chondrules come with a narrow range of sizes within each chondritic class. In general, the size distributions of CAIs and chondrules in chondrites can be determined from the initial size distribution as well as the distribution over the initial launching angle.
Determinants of Vacation Leave and Relations to Work Hours and Wages in Canadian Establishments

Using a nationally representative sample of employees and workplaces from Statistics Canadas Workplace Employee Survey (WES) 1999-2005, we provide new evidence on the determinants of vacation leave and its relationship to hours worked and hourly wages. Although paid vacation leave is an important factor in explaining variations in the gross domestic product (GDP) per capita as it has an impact on the number of annual hours worked, the literature has rarely focused on it. Previous studies have revealed that annual hours of work fall by 45 hours for each additional week of vacation used, i.e. by more than one week of full-time work. Correcting for bias due to the fact that workers revealed di¤erent preferences in the use of vacation and that workplaces may have di¤erent leave policies, we nd that annual hours of work fall by only 29 hours. Our results imply that reporting an extra week of vacation used translates less than one for one into a reduction in weeks worked. That is, failure to correct for unobserved e¤ects leads to an overestimate by approximately 55% of the impact of paid vacation on hours worked. Our ndings support the hypothesis that pressure at work may lead many employees to use vacation days more, but also causes them to work longer hours.

Are Brazilian Economists Different

The paper took its inspiration from a bargaining experiment recently conducted by Carter and lrons in the USA. It envolves an uItima­ tum game, where subject is asked to divide R$ 10 between himself and another anonymous individual. The Brazilian sample consisted of two groups of university students, the first one majoring in eco­ nomics and the other one majoring in social sciences. Empirical results show a c1ear deviation from the selfish rationality model, and suggest that a strong reason for this could be the im­ portance that moral norms such as fairness and equity have in the shaping of human behavior. However, as subjects are further trained in economic theory, they get c10ser to the selfish rationality mode! o artigo inspirou-se em experimento recentemente conduzido por Carter e Irons nos Estados Unidos. Envolve um jogo de ultimato, no qual o sujeito deve dividir R$ 10 entre ele e um outro individuo anonimo. A amostra brasileira consistiu de dois grupos de estudantes universitarios, sendo o primeiro deles do curso de economia e o se­ gundo do curso de ciencias sociais. Os resultados empiricos mostram um claro afastamento do modelo de racionalidade egoista, e sugerem que uma forte razao para tal pode ser a importância que normas morais como justica e equidade tem na moldagem do comportamento humano. Entretanto, a medida que os individuos recebem treinamento adicional em teoria economica, seu comportamento chega mais perto do modelo de racionalidade egoista.
Specific detection of Aspergillus fumigatus in sputum sample of pulmonary tuberculosis patients by two-step PCR

The incidence of life-threatening systemic fungal infections has been increasing in recent years, and the increasing incidence has been correlated with increasing numbers of immunocompromised patients. We developed a two-step PCR assay that specifically amplifies a region of the 18S rRNA gene that is highly conserved in Aspergillus fumigatus. This assay allows direct and rapid detection of down to 10 fg of Aspergillus fumigatus DNA corresponding to 1 to 5 colony forming unit (CFU) per ml of sputum sample of pulmonary tuberculosis patients. The two primer pairs that produced PCR products with the highest sensitivity and species specificity were the Aspergillus fumigatus primers AFU7S and AFU7AS, which amplified a fragment of 405 bp, followed by AFU5S and AFU5AS, which produced an internal fragment of 236 bp. PCR has been shown to be a highly sensitive diagnostic tool for the detection of infectious fungi specimens. Our point to the considerable potential clinical value of this simple, specific, rapid, and inexpensive PCR assay is for improving the means of early diagnosis of systemic aspergillosis tuberculosis patients.
SEE-SEP: From a separate to a holistic view on socio-scientific issues

The trend of socioscientific issues (SSIs) has been emergent in the science- and technology-dominated society of today. Accordingly, during the past 20 years, students’ skills of argumentation and informal reasoning about SSIs have achieved greater emphasis and profile in school education. Based upon the importance of SSIs, more and more researchers have investigated how students reason and make arguments about SSIs, and also explored the dimensions influencing students’ arguments and also involved in the various SSIs. This article has a threefold purpose. Firstly, we want to address the different roles of SSIs in science education nowadays, and secondly, after reviewing the divergent dimensions involved in SSIs from previous literature, we want to provide a holistic view to represent the essence of SSIs via the SEE-SEP model (connecting six subject areas of Sociology/culture, Environment, Economy, Science, Ethics/morality and Policy with three aspects of value, personal experience and knowledge) developed here. Thirdly, to support the SEE-SEP model, examples extracted from former studies are presented. The implications for research and for school science education are discussed.
Surfzone Wave Characteristics During Flood Tide on the Central West Coast of India

Surfzone wave characteristics, measured using a wave and tide gauge (WTG) during a flood tide, were studied at three different beaches having different nearshore slopes. The spectral wave characteristics viz., wave-height and mean wave period were estimated considering different sample sizes. Inter-comparisons of wave climate between each of three beaches for a similar tide level are presented. The wave-height and mean wave period values obtained from the wave analysis for each of the record using waves by wave method show that surfeone wave-height increased with time during a flood tide and the mean wave period decreased with time up to mid tide and then increased during the rest of the measurement period at Keri and Miramar beaches. At Candolim, the reversing trend of mean wave period increase is observed to occur much before reaching the mid tide level. The surfzone waves during a flood tide indicated that the wave-heights increased with time while the mean wave period showed a decreasing trend in general. The variation of breaker index showed a decreasing trend from low tide to high tide ranging between 0.45 and 0.23. The surf similarity parameter estimated corroborates with the visual observations.
Stock market integration between the CEE-4 and the G7 markets: Asymmetric DCC and smooth transition approach

We study the transition process of emerging CEE-4 stock markets from segmented to integrated markets and hypothesize that this process has been gradual over time. As a proxy for integration, co-movements with developed G7 markets are estimated using the asymmetric DCC-GARCH model. A smooth transition logistic trend model is then fitted to the dynamic correlations to examine the integration process. Evidence of strengthening relationships among the markets under study is provided. In the case of Czech stock market, the results suggest that the transition began between the end of 2005 and first half of 2006. The transition midpoints for the Hungarian and Polish markets seem to overlap with the recent financial crisis. Correlations between CEE-4 and G7 markets have been approximately 0.6 in the last few years. The only exception is the Slovak stock market, which still appears to be more segmented and isolated from others in the CEE region and from the developed markets of the G7.
Bone Subtraction 3-Dimension CT Angiography Using 64-Slice Multidetector CT for the Evaluation of Steno-Occlusive Intra- and Extracranial Vascular Diseases: Comparison with Digital Subtraction Angiography

CT angiography (CTA) is a noninvasive imaging method to detect arterial stenosis, cerebral aneurysm, and other vascular abnormalities. With the development of multidetector CT (MDCT) technology, the scan range and diagnostic accuracy of CTA has increased. But there are some limitations for the evaluation of intraand extracranial vascular diseases with conventional CTA technique. Separating vessels from the bone or perivascular calcifications can be difficult, particularly in areas such as the skull base (1). This limitation can be a barrier to its use in clinical practice. A further difficulty is that three dimenOriginal Article
Biochemical, Physiological and Horticultural Perspectives of Fruit Colour Pigmentation: A Review.

Plant pigments are essential for the attractiveness of fruits, accumulating most often in the skin during ripening process. The most important pigments of fruit include carotenoids and anthocyanins. Beside their role in pigmentation, they are important for human health as a source of vitamin A and antioxidant compounds. Carotenoids comprise carotenes, derived from terpenoids are synthesized in fruit at a high rate during the transition from chloroplast to chromoplast. Anthocyanins, a class of flavonoids derived ultimately from phenylalanine, are water-soluble, synthesized in the cytosol, and localized in vacuoles. They provide a wide range of colors ranging from orange/red to violet/blue. They are widely distributed in the plant kingdom. Betalains, nitrogen-containing water-soluble compounds derived from tyrosine, also conferring yellow-to-red colors, found only in a limited number of plant lineages. All three classes of pigments act as visible signals to attract insects, birds and animals for pollination and seed dispersal. They also protect plants from damage caused by UV and visible light. A number of factors and signals influence the accumulation of pigments includes light, temperature, hormones etc. With regard to that of horticultural perspectives, several orchard management practices found to influence better coloration in fruits.
Traditional poultry production: The role of women in Kaura-Namoda local government area, Zamfara State, Nigeria

Poultry production has a high priority because poultry meat has better energy and protein conversion ratio than many other animals. Traditional poultry is a well-known livestock enterprise in northern Nigeria and women contribute immensely to agricultural production but still their contribution to the country’s development remains largely not documented. This study therefore, aimed at assessing the role of rural women, their contribution and constraints to traditional poultry production in Kaura-Namoda local government area, Zamfara State-Nigeria. Sixty (60) women poultry keepers were randomly selected from twelve villages of four districts selected at random and administered with questionnaires to collect relevant data on socio-economic characteristics, management system adopted, output and constraints of poultry production. Data collected were analyzed using descriptive statistics. The result revealed that majority of the respondent were young (26-35 years) and married with no formal schooling whose kept between 11 to 20 bird with ratio of 1:2 of cock to hen. Extensive management system is practicing by the majority of respondent also; recorded more than 40 eggs laid by their hens with farm returns of N2000.00 to N5000.00 ($12.5 to $31.25) per week and sales their produce at market. Majority of the respondents provide local oral leaf and bark extract of mahogany and solanaceous plant for disease control while some uses local trap in controlling rodents, debeaked their birds to avoid cannivalism. Transportation, pest and diseases, weather changes, poor extension services and low capital are some of the constraints of poultry production in the study area. Key words: Traditional poultry, women, Kaura-Namoda.
Environmental Impacts of Tartaric Stabilisation Processes for Wines using Electrodialysis and Cold Treatment

The environmental impacts of the two tartaric stabilisation methods used for wines, electrodialysis and cold treatment, were studied by determining water consumption (for the process and cleaning), waste produced (organic load and the composition of wastewater and residues) and energy consumption, at the pilot stage and in wineries. Thanks to an online treatment of electrodialysis brines by reverse osmosis (industrial facility that treats 30 hL wine/h), the recycling of permeates led to a 65% reduction in water consumption, the volume of which represented only 3.9% of the wine treated. When washing and cleaning water from the ED-RO system was taken into account, overall water consumption was 5.5 L/hL wine. The presence of ethanol, due to an osmotic phenomenon with no loss of wine volume, and tartaric acid in the brines contributes to the organic load of the brine, with a COD of close to 8.4 g O2/L. Overall electrical energy consumption for stabilisation by electrodialysis (0.21 kWh/hL) turned out to be eight times lower than that of cold stabilisation. An evaluation of cold stabilisation effluents revealed that 66.6% of the COD discharged came from the diatomaceous earth (DE), 21.8% from the washing of the filter and 11.4% from the washing of the cold treatment tank. The production of used DE was 2.64 g (wet weight)/L of wine, and the ethanol present in the DE waste represented a loss in wine volume of 0.14 L/hL.

An offenderâ€™s perspective of what motivates and deters white-collar criminals in the South African workplace

The aim of this study was to investigate the motives of white-collar criminals so as to gain a better understanding of white-collar crime and develop measures that can help to reduce it. The study involved face-to-face interviews with white-collar offenders imprisoned at a correctional centre in South Africa. The data collected provided evidence to support the existing theory relating to the motives for white-collar crime; however, a previously unreported theme of race emerged as a key motivator among the respondents. Race was further identified as a key justification for committing the crime. Suggestions from the respondents to employment relations practitioners on how best to mitigate the risks were also collected and reported. The deterrents that were identified as most effective by the respondents revolved around four themes, namely reports and signing authority, working environment, education and matching roles and responsibilities.
Lecturers of Fine-Arts’ Digital Technology Utilization in Tertiary Institutions of North-Central Geo-Political Zone, Nigeria

Investigation on utilization of Digital Technology by lecturers of Fine-Arts in North-Central tertiary institutions in Nigeria was studied. Descriptive survey research type was used with researchers’ designed questionnaire; the population were Fine-Arts lecturers in Colleges of Education and Universities in North-Central, Nigeria. Purposive as well as simple random sampling techniques were used to select 100 lecturers of 50 male and 50 female. Three research questions were raised and two hypotheses formulated for the study. Simple percentage and means were used to answer the research questions, while hypotheses were tested with t-test and ANOVA at level 0.05 of significance. The findings revealed that the lecturers utilized some digital tools for their instructional delivery. Therefore, it is recommended that tertiary institutions in general and North-Central Nigeria in particular, should procure digital technology devices for lecturers’ utilization in instruction and that they should make use of them accordingly.

Variability, polarimetry, and timing properties of single pulses from PSR J1713+0747 using the Large European Array for Pulsars

Single pulses preserve information about the pulsar radio emission and propagation in the pulsar magnetosphere, and understanding the behaviour of their variability is essential for estimating the fundamental limit on the achievable pulsar timing precision. Here we report the findings of our analysis of single pulses from PSR J1713+0747 with data collected by the Large European Array for Pulsars (LEAP). We present statistical studies of the pulse properties that include distributions of their energy, phase and width. Two modes of systematic sub-pulse drifting have been detected, with a periodicity of seven and three pulse periods. The two modes appear at different ranges of pulse longitude but overlap under the main peak of the integrated profile. No evidence for pulse micro-structure is seen with a time resolution down to 140 ns. In addition, we show that the fractional polarization of single pulses increases with their pulse peak flux density. By mapping the probability density of linear polarization position angle with pulse longitude, we reveal the existence of two orthogonal polarization modes. Finally, we find that the resulting phase jitter of integrated profiles caused by single pulse variability can be described by a Gaussian probability distribution only when at least 100 pulses are used for integration. Pulses of different flux densities and widths contribute approximately equally to the phase jitter, and no improvement on timing precision is achieved by using a subset of pulses with a specific range of flux density or width.
THE ASSESSMENT OF NK CYTOTOXICITY AND CD56+/CD16+ PHENOTYPE BY FLOWCYTOMETRYIN PBL ISOLATED FROM WOMEN WITH RECURRENT SPONTANEOUS ABORTION

Background: Human peripheral blood NK cells constitutively express CD56 and CD16 antigens. Peripheral blood NK cells seem to be strongly related with decidual NK cells, and may reflect the decidual NK cell functional status. There are varied reports concerning the relationship between NK cell cytotoxicity in women with recurrent spontaneous abortion. Objective: To study NK activity in women with history of RSA by using a non-radioactive cytotoxicity assay. Methods: Peripheral blood lymphocytes from RSA and healthy multiparous women were obtained. Lymphocytes were isolated and mixed with K562 NK-sensitive cell line. A non-radioactiv e method for NK cell cytotoxicity assessment was utilized. Dead K562 cell populations were detected by FACS Calibur flow cytometry, and the data obtained was analysed on cell-Quest software. The proportion of CD16 + /CD56 + cells was then calculated. Results: The proportion of NK cells were 9.21% ± 3.06 and 13.48% ± 4.09 in healthy women and RSA, respectively. The percentage of cytotoxicity was determined to be 19.3% ± 3.9 in healthy group and 27.1% ± 6.5 in RSA group with an effector:target ratio of 50:1. The data shows an increase in PBLs potential for in vitro cytotoxicity assay in RSA individuals. The analyses indicate that there is a weak positive correlation between NK cytotoxicity potential and the percentage of NK cells in PBL population. Conclusion: The present study demonstrates that the percentage of CD56 + /CD16 + cells increases in individuals with recurrent spontaneous abortion. We conclude that NK cytotoxicity as well as NK number is partially involved in RSA.
