    A fundamental advantage for performing material processing and fluid physics experiments in an orbital environment is the reduction in gravity driven phenomena. However, experience with manned spacecraft such as the Space Transportation System (STS) has demonstrated a dynamic acceleration environment far from being characterized as a 'microgravity' platform. Vibrations and transient disturbances from crew motions, thruster firings, rotating machinery etc. can have detrimental effects on many proposed microgravity science experiments. These same disturbances are also to be expected on the future space station. The Microgravity Science and Applications Division (MSAD) of the Office of Life and Microgravity Sciences and Applications (OLMSA), NASA Headquarters recognized the need for addressing this fundamental issue. As a result an Advanced Technology Development (ATD) project was initiated in the area of Vibration Isolation Technology (VIT) to develop methodologies for meeting future microgravity science needs. The objective of the Vibration Isolation Technology ATD project was to provide technology for the isolation of microgravity science experiments by developing methods to maintain a predictable, well defined, well characterized, and reproducible low-gravity environment, consistent with the needs of the microgravity science community. Included implicitly in this objective was the goal of advising the science community and hardware developers of the fundamental need to address the importance of maintaining, and how to maintain, a microgravity environment. This document will summarize the accomplishments of the VIT ATD which is now completed. There were three specific thrusts involved in the ATD effort. An analytical effort was performed at the Marshall Space Flight Center to define the sensitivity of selected experiments to residual and dynamic accelerations. This effort was redirected about half way through the ATD focusing specifically on the sensitivity of

    A new wireless sensor network (WSN), called CrossVit, and based on MEMSIC products, has been tested for two growing seasons in two vineyards in Italy. The aims are to evaluate the monitoring performances of the new WSN directly in the vineyard and collect air temperature, air humidity and solar radiation data to support vineyard management practices. The WSN consists of various levels: the Master/Gateway level coordinates the WSN and performs data aggregation; the Farm/Server level takes care of storing data on a server, data processing and graphic rendering; Nodes level is based on a network of peripheral nodes consisting of a MDA300 sensor board and Iris module and equipped with thermistors for air temperature, photodiodes for global and diffuse solar radiation, and an HTM2500LF sensor for relative humidity. The communication levels are: WSN links between gateways and sensor nodes by ZigBee, and long-range GSM/GPRS links between gateways and the server farm level. The system was able to monitor the agrometeorological parameters in the vineyard: solar radiation, air temperature and air humidity, detecting the differences between the canopy treatments applied. The performance of CrossVit, in terms of monitoring and reliability of the system, have been evaluated considering: its handiness, cost-effective, non-invasive dimensions and low power consumption.

    The present study addresses carbon storage and sequestration by trees grown in VIT University campus, Vellore. Approximately twenty trees were selected from Woodstockarea. The above ground biomass and below ground biomass were calculated. The above ground biomass includes non-destructive anddestructive sampling. The Non-destructive method includes the measurement of height of thetree and diameter of the tree. The height of the tree is calculated using Total Station instrument and diameter is calculated using measuring tape. In the destructive method the weight of samples (leaves) and sub-samples (fruits, flowers) of the tree were considered. To calculate the belowground biomass soil samples are taken and analyzed. The results obtained were used to predict the carbon storage. It was found that out of twenty tree samples Millingtonia hortensis which is commonly known as Cork tree possess maximum carbon storage (14.342kg/tree) and carbon sequestration (52.583kg/tree) respectively.

    Full Text Available Connaître la longévité d’un pollen est une donnée particulièrement intéressante dans le cadre des études de risques de dissémination du pollen. En effet, cela permet de savoir combien de temps une parcelle dont la floraison est terminée reste une source de pollen fécondant. Par ailleurs, une étude de la longévité du pollen pourrait permettre de mieux comprendre les résultats en apparence contradictoires obtenus au cours de diverses expérimentations menées sur la dissémination du pollen de colza. Ainsi, alors que des travaux montrent que ce pollen est peu anémophile [1] et qu’au niveau de la parcelle sa dispersion se fait sur de courtes distances [2-4], des cas de contaminations sur de grandes distances ont été signalés [5] et les relevés palynologiques effectués sur des filtres (placés à 10 m de hauteur, voire plus confirment que ce pollen peut se disperser sur de grandes distances [6]. Toutefois, on ignore si le pollen ainsi collecté est viable ou non. Si l’on fait l’hypothèse que cette dernière dispersion se fait par le biais de la mise en suspension du pollen dans l’air dans les couches de l’atmosphère et que son transport dure un certain temps, il devient également nécessaire de connaître la durée de vie du pollen pour mieux évaluer les risques de ce type de dissémination. Au plan méthodologique, mesurer la longévité du pollen peut a priori paraître simple. Cependant les critères retenus peuvent être nombreux et divers : mesure de la viabilité, mesure du pouvoir germinatif in vitro ou in vivo, mesure du pouvoir fécondant réel. Dans chacun des cas, les techniques appliquées sont différentes et chacune comporte des biais parfois importants tels que des faux-positifs dans les tests colorimétriques de viabilité, l’incidence du milieu de culture dans les tests de germination in vitro, sans parler des tests présentant des risques carcinogènes pour l’expérimentateur [7].

    It is well recognized that dilution is an important mechanism governing the near-road air pollutant concentrations. In this paper, we aim to advance our understanding of turbulent mixing mechanisms on and near roadways using computation fluid dynamics. Turbulent mixing mechanisms can be classified into three categories according to their origins: vehicle-induced turbulence (VIT), road-induced turbulence (RIT), and atmospheric boundary layer turbulence. RIT includes the turbulence generated by road embankment, road surface thermal effects, and roadside structures. Both VIT and RIT are affected by the roadway designs. We incorporate the detailed treatment of VIT and RIT into the CFD (namely CFD-VIT-RIT) and apply the model in simulating the spatial gradients of carbon monoxide near two major highways with different traffic mix and roadway configurations. The modeling results are compared to the field measurements and those from CALINE4 and CFD without considering VIT and RIT. We demonstrate that the incorporation of VIT and RIT considerably improves the modeling predictions, especially on vertical gradients and seasonal variations of carbon monoxide. Our study implies that roadway design can significantly influence the near-road air pollution. Thus we recommend that mitigating near-road air pollution through roadway designs be considered in the air quality and transportation management In addition, thanks to the rigorous representation of turbulent mixing mechanisms, CFD-VIT-RIT can become valuable tools in the roadway designs process.

    In the oil sands industry, steam assisted gravity drainage (SAGD) is a thermal recovery method. During the preheating of an SAGD well pair, high quality steam is injected down hole through the long string while return fluids are returned to the surface through the short string; this situation leads to unwanted heat exchanges between the two. The aim of the study is to determine the possible benefits of using acuum insulated tubing (VIT), a technology which manages downhole temperature successfully, in the SAGD process. A theoretical analysis and a field test were conducted on 2 injection wells in an in-situ oil sands project in Surmont in the Athabasca area. Results showed that the use of VIT improves heat transfer efficiency, leading to lower steam injection requirements and a reduction of concerns relating to thermal expansion and well integrity. This paper demonstrated that the application of VIT to the SAGD process is beneficial.

    The Cao Vit gibbon (Nomascus nasutus) has only one population with about 110 individuals living in a degraded karst forest along the China-Vietnam border. Investigation of food choice in relation to chemical nutrition will offer important insights into its conservation. We studied the food choice of two groups of Cao Vit gibbons using instantaneous scan sampling in Bangliang National Nature Reserve, Guangxi, China, over 4 years, and analyzed the chemical components (total nitrogen, TN; water-soluble sugar, WSS; crude fat, CF; neutral detergent fiber, NDF; acid detergent fiber, ADF; acid detergent lignin, ADL; condensed tannin, CT; and ash) of 48 food plant parts and 22 non-food plant parts. Fruits and figs that are rich in sugar are important food resources for gibbons. For other food types, flowers are a good source of total nitrogen and carbohydrates, and leaves and buds provide sources of protein and minerals. Cao Vit gibbons selected fruits that contain less total nitrogen, less acid detergent fiber and more water-soluble sugar than non-food fruits. Several food species that were heavily consumed by Cao Vit gibbons are suggested as potential tree species for ongoing habitat restoration.

    This study showed that both microemulsions provided good solubility of Vit B12 with a wide range of internal structure. Low water solubilization capacity is a common property of microemulsions that can affect drug release and permeability through the skin. Based on Vit B12 properties, specially, intermediate oil and water solubility, better drug partitioning into the skin may be obtained by traditional formulations with wide range of structure and high amount of free and bounded water.

    Terceira island (Azores) have experienced several strong earthquakes, especially on the eastern and south-eastern part of the island with maximum MM intensity of VIII in 1800, 1801 and 1912 and IX in 1614 and 1841. Seismicity of the eastern part of the island is largely dominated by the tectonic of the NW-SE Lajes graben where are located Praia da Vitória and other setlements. Praia da Vitória is settled partially over pyroclastic material(pumice and ignimbrite) deposited around 20'000 years ago and forming part of the UpperTerceira Group. Its thickness is 15m on the north but in Praia da Vitoria has less than one meter.. It is sited on by basaltic flow of the upper Basaltic Terceira Group (2,000y BP) and a thick andesitic lava flow. A narrow band with sand dunes and beach crossed this deposits along Praia da Vitória and behind it appear a flat area with 7-10m of round cobbles that is interpreted as an old boulders'beach. Thickness of these different deposits are tricky to estimate in urban areas since very few outcrops are present. In order to assess site amplification of seismic waves due to the soil conditions, we perform horizontal-to-vertical spectral ratio (HVSR) method from broad band ambient noise measurements in 51 different sites within Praia da Vitoria. The first results show that the frequencies of the study area are variable, lying between 0.6-12 Hz.

    Vacuolar iron transporters (VITs) are a poorly understood family of integral membrane proteins that can function in iron homeostasis via sequestration of labile Fe2+ into vacuolar compartments. Here we report on the heterologous overexpression and purification of PfVIT, a vacuolar iron transporter homologue from the human malaria-causing parasite Plasmodium falciparum. Use of synthetic, codon-optimised DNA enabled overexpression of functional PfVIT in the inner membrane of Escherichia coli which, in turn, conferred iron tolerance to the bacterial cells. Cells that expressed PfVIT had decreased levels of total cellular iron compared with cells that did not express the protein. Qualitative transport assays performed on inverted vesicles enriched with PfVIT revealed that the transporter catalysed Fe2+/H+ exchange driven by the proton electrochemical gradient. Furthermore, the PfVIT transport function in this system did not require the presence of any Plasmodium-specific factor such as post-translational phosphorylation. PfVIT purified as a monomer and, as measured by intrinsic protein fluorescence quenching, bound Fe2+ in detergent solution with low micromolar affinity. This study of PfVIT provides material for future detailed biochemical, biophysical and structural studies to advance understanding of the vacuolar iron transporter family of membrane proteins from important human pathogens.

    Full Text Available No planejamento experimental, a parcela experimental é um fator determinante para o sucesso da pesquisa. Portanto, é necessário que o pesquisador defina adequadamente a constituição da parcela ou unidade experimental, no intuito de aumentar a eficiência do experimento e diminuir o erro experimental. Em decorrência da grande variabilidade no tamanho da parcela encontrada nos experimentos com abacaxizeiro, realizou-se uma pesquisa objetivando estimar o tamanho ótimo para parcelas experimentais, considerando diferentes características. Os dados utilizados para este trabalho foram coletados em 100 plantas de abacaxizeiro 'Vitória'. Foram coletados 100 frutos e 100 folhas "D" de plantas cultivadas na mesma área experimental e submetidas às mesmas práticas de cultivo. Foram avaliados nos frutos: o comprimento, o diâmetro e a massa. Na folha "D", foram avaliados o comprimento e a massa, além dos teores de N, P e K. As estimativas do tamanho da parcela foram baseadas nos métodos do modelo linear de resposta a platô e da curvatura máxima. O tamanho ótimo da parcela para a avaliação do abacaxizeiro 'Vitória' é de 15 a 20 unidades experimentais por parcela, para as características dos frutos e das folhas, pelo método do modelo linear de resposta a platô. Para a avaliação dos teores de N, P e K, 10 folhas representam o tamanho ótimo da parcela pelo método do modelo linear de resposta a platô. Por outro lado, o tamanho ótimo da parcela para avaliação dos frutos e das folhas do abacaxi 'Vitória' é de 1,7 a 2,8 unidades experimentais pelo método da curvatura máxima. Enquanto, para os teores de N, P e K, 3 a 5 unidades experimentais representam o tamanho ótimo da parcela pelo método da curvatura máxima.

    Full Text Available The nutritional state of the pineapple plant has a large effect on plant growth, on fruit production, and fruit quality. The aim of this study was to assess the uptake, accumulation, and export of nutrients by the irrigated 'Vitória' pineapple plant during and at the end of its development. A randomized block statistical design with four replications was used. The treatments were defined by different times of plant collection: at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP. The collected plants were separated into the following components: leaves, stem, roots, fruit, and slips for determination of fresh and dry matter weight at 65 ºC. After drying, the plant components were ground for characterization of the composition and content of nutrients taken up and exported by the pineapple plant. The results were subjected to analysis of variance, and non-linear regression models were fitted for the significant differences identified by the F test (p N > S > Ca > Mg > P, which corresponded to 898, 452, 134, 129, 126, and 107 kg ha-1, respectively, of total accumulation. The export of macronutrients by the pineapple fruit was in the following decreasing order: K > N > S > Ca > P > Mg, which was equivalent to 18, 17, 11, 8, 8, and 5 %, respectively, of the total accumulated by the pineapple. The 'Vitória' pineapple plant exported 78 kg ha-1 of N, 8 kg ha-1 of P, 164 kg ha-1 of K, 14 kg ha-1 of S, 10 kg ha-1 of Ca, and 6 kg ha-1 of Mg by the fruit. The nutrient content exported by the fruits represent important components of nutrient extraction from the soil, which need to be restored, while the nutrients contained in the leaves, stems and roots can be incorporated in the soil within a program of recycling of crop residues.

    Full Text Available This study aimed to evaluate the growth characteristics of irrigated Vitória pineapple plants grown in semi-arid conditions and determine its developmental stages based on those characteristics. It was used a randomized block design with four replicates. The experimental treatments were: plant harvest at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP. The following variables were determined: plant height, stem diameter, D-leaf length, D-leaf fresh and dry mass, biomass production of plants and plant parts (organs, and vegetative biomass. Five phenological stages are proposed based on vegetative biomass production: 80% (V5. The maximum growth rate for plant height, D-leaf length, and stem diameter was observed at the end of the phenological stage V1 (390-411 DAP, and at the end of stage V5 these plant traits had average values of 106, 82, and 7 cm, respectively. The maximum biomass accumulation rates were observed at stages V4 and V5, resulting in a final fruit yield and total fresh biomass of 72 t ha-1 and 326 t ha-1, respectively. Finally, we estimated that 80% of the accumulated biomass may remain in the field after fruit and slip harvest, and could be incorporated as plant residue into the soil.

    Studies about sexual risk behaviors can provide information to support design strategies to control the spread of HIV infection. To assess sexual risk behaviors among women attending a sexually transmitted diseases clinic in Vitória, Brazil. A cross-sectional study was performed among women attending an STD/AIDS reference center. Enrolled participants were interviewed and provided a blood sample to determine HIV status. A total of 276 women participated. among 284 selected; 109 (39.5%) were HIV-positive and 167 (60.5%) HIV-negative. Median age was 31 years (interquartile range (IQR)24-36) and 69% of women were between 18 and 34 years of age. Women reported high access to information about STD (87%) and AIDS (90%) but information about sexuality was less common (55%). HIV-positive women asked their partners to use condoms more often than HIV-negatives (31% vs. 5%, p=0.02), and were more likely to have used a condom at last intercourse (65% vs. 33%, psexual intercourse (99.6%) and needle sharing (99.2%) were most frequently answered correctly, while questions regarding risk of HIV transmission through blood donation (57%) were least. Though this population reports easy access to information and services for HIV/sexually transmitted diseases, most report little understanding of unsafe sexual behaviors, particularly HIV-negative women.

    Motor vehicles generate vehicle-induced turbulence (VIT) while in motion, which affects the mixing and transport of emitted trace gases, heat and momentum. During July, 2016 a 40Hz sonic anemometer (ATI) and a co-located 20Hz open path CO2/H2O gas analyzer (LICOR) were assembled and driven on highways in the Greater Toronto Area. An ultra-high sensitivity aerosol spectrometer was employed to measure the total number concentration of particles between 60 and 1000nm at the position of the gas analyzer and sonic anemometer. A video camera with GPS capabilities was also utilized to assess the surrounding features while chasing a specific vehicle type. The following distance of each chased vehicle is calculated as a function of pixel location, with the back edge of each followed vehicle being identified as the initial contrast between the vehicle's shadow and the roadway. Combining the sonic anemometer data with the GPS data allows turbulence statistics to be developed and correlations with vehicle type and following distance to be examined. Vehicle-induced turbulence is assessed using turbulent kinetic energy (TKE), a measure of turbulent mixing, which maximizes near the followed vehicle and decreases with increasing following distance. Vehicle exhaust plumes are identified using the measured CO2 concentration. The CO2 concentration data in conjunction with TKE and turbulent fluxes are used to explore the potential impacts of vehicle-induced turbulence on atmospheric mixing within the surface layer.

  12. Individuality and stability in male songs of cao vit gibbons (Nomascus nasutus with potential to monitor population dynamics.

    Directory of Open Access Journals (Sweden)

    Jun-Juan Feng

    Full Text Available Vocal individuality and stability has been used to conduct population surveys, monitor population dynamics, and detect dispersal patterns in avian studies. To our knowledge, it has never been used in these kinds of studies among primates. The cao vit gibbon is a critically endangered species with only one small population living in a karst forest along China-Vietnam border. Due to the difficult karst terrain, an international border, long life history, and similarity in male morphology, detailed monitoring of population dynamics and dispersal patterns are not possible using traditional observation methods. In this paper, we test individuality and stability in male songs of cao vit gibbons. We then discuss the possibility of using vocal individuality for population surveys and monitoring population dynamics and dispersal patterns. Significant individuality of vocalization was detected in all 9 males, and the correct rate of individual identification yielded by discriminant function analysis using a subset of variables was satisfactory (>90%. Vocal stability over 2-6 years was also documented in 4 males. Several characters of cao vit gibbons allowed long-term population monitoring using vocal recordings in both China and Vietnam: 1 regular loud calls, 2 strong individuality and stability in male songs, 3 stable territories, and 4 long male tenure. During the course of this research, we also observed one male replacement (confirmed by vocal analysis. This time- and labor-saving method might be the most effective way to detect dispersal patterns in this transboundary population.

    Blue color in flowers is due mainly to anthocyanins, and a considerable part of blue coloration can be attributed to metal-complexed anthocyanins. However, the mechanism of metal ion transport into vacuoles and subsequent flower color development has yet to be fully explored. Previously, we studied the mechanism of blue color development specifically at the bottom of the inner perianth in purple tulip petals of Tulipa gesneriana cv. Murasakizuisho. We found that differences in iron content were associated with the development of blue- and purple-colored cells. Here, we identify a vacuolar iron transporter in T. gesneriana (TgVit1), and characterize the localization and function of this transporter protein in tulip petals. The amino acid sequence of TgVit1 is 85% similar that of the Arabidopsis thaliana vacuolar iron transporter AtVIT1, and also showed similarity to the AtVIT1 homolog in yeast, Ca(2+)-sensitive cross-complementer 1 (CCC1). The gene TgVit1 was expressed exclusively in blue-colored epidermal cells, and protein levels increased with increasing mRNA expression and blue coloration. Transient expression experiments revealed that TgVit1 localizes to the vacuolar membrane, and is responsible for the development of the blue color in purple cells. Expression of TgVit1 in yeast rescued the growth defect of ccc1 mutant cells in the presence of high concentrations of FeSO(4). Our results indicate that TgVit1 plays an essential role in blue coloration as a vacuolar iron transporter in tulip petals. These results suggest a new role for involvement of a vacuolar iron transporter in blue flower color development.

    Full Text Available Muscular tissue from wild-caught mullet (Mugil spp. and snook (Centropomus spp. was analyzed by atomic absorption spectrometry to determine muscle contamination levels for cadmium, chromium, copper, lead and zinc and evaluate risks to human health associated with seafood consumption. Fishes were captured by subsistence fishermen in Vitória Bay, a Brazilian tropical estuary with numerous outfalls of untreated industrial and residential sewage. Based on the premisses that subsistence fisherman and local consumer show weak (culinary or other preferences within the taxa studied, analyses were conducted and results are reported for genera. Snook cadmium, chromium, copper and zinc concentrations were positively correlated with size or weight. Mullet chromium concentration decreased with size. Cadmium and lead were higher and zinc lower in mullet than in snook. Summer cadmium and lead concentrations were higher than in winter. Chromium presented concentrations consistently over the legal Brazilian limit for seafood. However, the greatest health concern was probably related to lead concentration, especially in respect to consumption by young children.Tecidos musculares de tainhas (Mugil sp. e robalos (Centropomus sp. foram analisados por espectrometria de absorção atômica para determinar as concentrações dos metais cádmio, cromo, cobre, chumbo e zinco no músculo e avaliar os riscos a saúde humana resultante do consumo do pescado.

    Streptokinase purified from Streptococcus equinus VIT_VB2 isolated from bovine milk sample was immobilized in various solid supports namely entrapment in agarose gel, calcium alginate beads and gelatin gel by cross-linking with formaldehyde. Immobilization of streptokinase in calcium alginate beads showed maximum efficiency (81.8 ± 1.06%) when compared with entrapment with agarose gel (55.6 ± 2.17%) and cross-linked gelatin formaldehyde gel (71.0 ± 1.54%). The purified SK activity was expressed maximum in calcium alginate (1%) and gelatin gel (0.25%) with 1292.68 ± 1.33 and 1121.9 ± 1.2 U mL -1 , respectively. Similarly, SK entrapped in gelatin gel and calcium alginate showed maximum in vitro blood clot lysis activity with 77.67 ± 2.64% and 76.16 ± 2.72%, respectively. The immobilized SK in gelatin gel showed complete clot lysis within 15 min; hence, this application of the study could be used in the treatment of superficial thrombophlebitis, phlebitis, and venous thrombosis. These beads were used for three repeated cycles to check the conversion of substrates into their products, and we concluded that SK can be immobilized in the suitable matrices. Therefore, this helps in the drug-delivery strategies in highly efficient way, moreover, economically competent process in the pharmaceutics.

  17. Internal Tide Generation at the Vitória-Trindade Ridge - South Atlantic

    The generation, propagation and surface manifestation of internal tides at the Vitória-Trindade Ridge, a 950 km long east-west submarine seamount chain located around 20°S in the southwestern South Atlantic, were investigated using 20 years of sea surface height anomaly data from different satellite altimeters, and numerical results from a high resolution regional HYCOM simulation. We found a dominant phase-locked semidiurnal internal tide generated at the ridge, with surface amplitude of 2.5 cm and wavelength of 120 km for the M2 component. Smaller amplitudes, between 1.0 and 2.0 cm were associated to the S2 component. The M2 internal tide radiate both poleward and equatorward for more than 1000 km, before decaying below noise level. Numerical results indicate maximum isopicnal displacements on the order of 100 m at thermocline levels, and a coherent mode-1 M2 internal tide energy flux around 100 W/m. Although smaller than fluxes reported in highly energetic regions such as the Hawaiian Islands, this value is significant when compared to fluxes generated nearby at the Brazilian slope. The results also indicate that the ridge geometry acts as a lens for the poleward propagating internal tide, with a focal region located about 300 km to the south. Chlorophyll-a maps of the South Atlantic show that the Vitoria-Trindade Ridge seamounts are hot-spots of high phytoplankton biomass, surrounded by oligotrophic oceanic waters. It is hypothesized that the locally generated internal tides may play an important role in sustaining the observed complex marine food webs, by bringing nutrient-rich subsurface waters to the euphotic zone.

    The scientific literature on teachers' health is scarce, recent, and focuses predominantly on stress and burnout. This study describes the labor conditions of private school teachers in Vitória da Conquista, Bahia State, Brazil. Information on 250 teachers from the ten largest schools in the municipality was collected through a self-applied questionnaire. The most relevant characteristics of teachers' work, evaluated by the Job Content Questionnaire were: speed of work, creativity at work, and relations with colleagues. The most frequent complaints related to posture, mental strain, and voice problems. Prevalence of minor psychological disorders according to the Self Reporting Questionnaire-20 was 41.5%, strongly associated with long periods of intense concentration on the same job and excessive work. Results suggest an association between the prevalence of minor psychological disorders and certain characteristics of teaching work, emphasizing teachers' exposure to stress.

    Full Text Available This paper addresses topics on Health Education and risk behavior. Research was carried out to investigate how users deal with information received from a Health Education program, in Vitória (Espírito Santo, Brazil, focused on intervention in overweight and obese individuals. The methodological tools used were participant observation, semi-structured interviews and experimentation with the technique of Body-Map Storytelling. We conclude that the individuals showed evidence of conformity by absorbing and conveying the behavior recommended by experts to their daily lives. We believe that this finding is linked to the fact that, in contemporary society, the model of living well corresponds to healthy lifestyle, in which the “naturalization” of these ideals ultimately contributes to the acceptance of these norms due to the belief that this would be the only right way of living.

Most humpback whale groups (N = 7; 78% were observed in the Vitória-Trindade seamounts, especially the mounts close to the Abrolhos Bank. Only one lone humpback whale was observed near Trindade Island after a search effort encompassing more than 520 km. From a total of 28 acoustic stations, humpback whale songs were only detected near the seamounts close to the Abrolhos Bank, where most groups of this species were visually detected (including a competitive group and groups with calves. The presence of humpback whales at the Trindade Island and surroundings is most likely occasional, with few sightings and low density. Finally, we observed a significant number of humpback whales along the seamounts close to the Abrolhos Bank, which may function as a breeding habitat for this species. We also added important records regarding the occurrence of cetaceans in these mounts and in the Western South Atlantic, including the endangered fin whale.

    Several flowers of Tulipa gesneriana exhibit a blue color in the bottom segments of the inner perianth. We have previously reported the inner-bottom tissue-specific iron accumulation and expression of the vacuolar iron transporter, TgVit1, in tulip cv. Murasakizuisho. To clarify whether the TgVit1-dependent iron accumulation and blue-color development in tulip petals are universal, we analyzed anthocyanin, its co-pigment components, iron contents and the expression of TgVit1 mRNA in 13 cultivars which show a blue color in the bottom segments of the inner perianth accompanying yellow- and white-colored inner-bottom petals. All of the blue bottom segments contained the same anthocyanin component, delphinidin 3-rutinoside. The flavonol composition varied with cultivar and tissue part. The major flavonol in the bottom segments of the inner perianth was rutin. The iron content in the upper part was less than that in the bottom segments of the inner perianth. The iron content in the yellow and white petals was higher in the bottom segment of the inner perianth than in the upper tissues. TgVit1 mRNA expression was apparent in all of the bottom tissues of the inner perianth. The result of a reproduction experiment by mixing the constituents suggests that the blue coloration in tulip petals is generally caused by iron complexation to delphinidin 3-rutinoside and that the iron complex is solubilized and stabilized by flavonol glycosides. TgVit1-dependent iron accumulation in the bottom segments of the inner perianth might be controlled by an unknown system that differentiated the upper parts and bottom segments of the inner perianth.

Nesse sentido, o objetivo deste trabalho foi comparar os frutos, a partir de parâmetros químicos e físicos, e também observar os dados produtivos das plantas de três populações de butiazeiros do município de Santa Vitória do Palmar-RS. Os dados foram obtidos em experimentos conduzidos na safra de 2005/2006 e na safra de 2006/2007, em três propriedades localizadas em Santa Vitória do Palmar. Os resultados permitiram verificar que as propriedades e ou variações genéticas entre as populações de Butia capitata avaliadas propiciaram variabilidade para duração do ciclo, coloração da epiderme dos frutos, volume de suco produzido, relação entre sólidos solúveis totais e acidez titulável, características biométricas de fruto e produtividade anual. Uma das populações, denominada Celina, apresentou maior produtividade e rendimento industrial. As populações Celina e São José apresentaram as melhores características biométricas de fruto. A população Aguiar apresentou a melhor relação entre sólidos solúveis totais e acidez titulável.The genus Butia belongs to the Arecaceae family and shows five species occurring in Rio Grande de Sul. The specie Butia capitata requires special attention, not just for its use as fresh consumption but also as processed product. However, even having its use recorded since

    Many chronic heart failure (CHF) patients have low vitamin D (VitD) and high plasma renin activity (PRA), which are both associated with poor prognosis. Vitamin D may inhibit renin transcription and lower PRA. We investigated whether vitamin D3 (VitD3) supplementation lowers PRA in CHF patients. We conducted a single-center, open-label, blinded end point trial in 101 stable CHF patients with reduced left ventricular ejection fraction. Patients were randomized to 6 weeks of 2,000 IU oral VitD3 daily or control. At baseline, mean age was 64 ± 10 years, 93% male, left ventricular ejection fraction 35% ± 8%, and 56% had VitD deficiency. The geometric mean (95% CI) of 25-hydroxyvitamin D3 increased from 48 nmol/L (43-54) at baseline to 80 nmol/L (75-87) after 6 weeks in the VitD3 treatment group and decreased from 47 nmol/L (42-53) to 44 nmol/L (39-49) in the control group (P CHF patients had VitD deficiency and high PRA levels. Six weeks of supplementation with 2,000 IU VitD3 increased 25-hydroxyvitamin D3 levels and decreased PRA and plasma renin concentration. Copyright © 2013 Mosby, Inc. All rights reserved.

O Aedes aegypti, responsável por epidemias de dengue em cidades brasileiras, representa sério risco também para a febre amarela. Com o insucesso da campanha de erradicação do inseto, justifica-se a busca de criadouros fora do alcance das medidas de controle atualmente adotadas. Na Cidade de Vitória, ES, investigou-se a ocorrência de criadouros de Aedes aegypti na água coletada em bromélias nativas, sobre as rochas. Paralelamente, avaliou-se a infestação predial nas áreas urbanas contíguas. Em quatro das cinco áreas investigadas foram encontradas larvas de culicídeos nas bromélias, sendo que em duas foi identificado Aedes aegypti. A presença dos criadouros em bromélias não guardou relação com a infestação predial nas áreas próximas. Torna-se necessário definir se os criadouros em bromélias constituem focos primários do Aedes aegypti, ou se representam uma conseqüência da elevada infestação urbana.Some insects that are vectors of human diseases have accompanied man in his migrations throughout the world and breed exclusively in the proximity of human dwellings. The mosquito Aedes aegypti has been responsible for epidemics of dengue in Brazil and its presence also constitutes a serious risk for future outbreaks of urban yellow fever. The failure of campaigns to eradicate this species justifies the search for alternative breeding sites, which may be beyond the reach of present control measures. In this study the occurrence of Aedes aegypti breeding sites in native bromeliads on rocky slopes was investigated in five areas of Vitória, capital of the Brazilian State of Espírito Santo, ES. Water contained in the bromeliads was collected with the aid of a suction apparatus to search for culicid larvae.

    A cross-sectional study with all the teachers in the municipal school system in Vitória da Conquista, Bahia State, Brazil, investigated the association between work content (psychological demand and control over work) and the occurrence of minor psychiatric disorders (MPD) among teachers. The Karasek demand-control model was used to evaluate control over work. The Self-Report Questionnaire-20 was used to evaluate minor psychiatric disorders. MPD prevalence was 55.9% among the 808 teachers studied. Crude prevalence of MPD showed a positive and significant association with psychological demand and a negative and significant association with control over work. MPD prevalence was higher in teachers with highly demanding work, characterized by heavy demand and low control (PR = 1.74; 95%CI: 1.44-2.10), and in those with active work, with heavy demand and low control (PR = 1.35; 95%CI: 1.13-1.61), as compared to teachers with low-demand work (light demand and high control), after adjusting for confounders in a multiple logistic regression model. As a conclusion, teachers' mental health is strongly associated with their work content.

    Pineapple is the fruit of Ananas comosus var. comosus plant, being cultivated in tropical areas and has high energy content and nutritional value. Herein, 30 samples of pineapple cv. Vitória were analyzed as a function of the maturation stage (0-5) and their physico-chemical parameters monitored. In addition, negative-ion mode electrospray ionization mass spectrometry [ESI(-)FT-ICR MS] was used to identify and semi-quantify primary and secondary metabolites present in the crude and phenolic extracts of pineapple, respectively. Physico-chemical tests show an increase in the total soluble solids (TSS) values and in the TSS/total titratable acidity ratio as a function of the maturity stage, where a maximum value was observed in stage 3 (¾ of the fruit is yellow, which corresponds to the color of the fruit peel). ESI(-)FT-ICR MS analysis for crude extracts showed the presence mainly of sugars as primary metabolites present in deprotonated molecule form ([M - H]- and [2 M - H]- ions) whereas, for phenolic fractions, 11 compounds were detected, being the most abundant in the third stage of maturation. This behavior was confirmed by quantitative analysis of total polyphenols. ESI-FT-ICR MS was efficient in identifying primary (carbohydrates and organic acids) and secondary metabolites (13 phenolic compounds) presents in the crude and phenolic extract of the samples, respectively. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Full Text Available The events involved in the structural interaction between the diazotrophic endophytic bacterium Herbaspirillum seropedicae, strain RAM10, labeled with green fluorescent protein, and pineapple plantlets 'Vitória' were evaluated by means of bright-field and fluorescence microscopy, combined with scanning electron microscopy for 28 days after inoculation. After 6 hours of inoculation, H. seropedicae was already adhered to the roots, colonizing mainly root hair surface and bases, followed by epidermal cell wall junctions. Bacteria adherence in the initial periods occurred mainly in the form of solitary cells and small aggregates with pleomorphic cells. Bacteria infection of root tissue occurred through the cavities caused by the disruption of epidermal cells during the emergence of lateral roots and the endophytic establishment by the colonization of intercellular spaces of the cortical parenchyma. Moreover, within 1 day after inoculation the bacteria were colonizing the shoots. In this region, the preferred sites of epiphytic colonization were epidermal cell wall junctions, peltate scutiform trichomes and non-glandular trichomes. Subsequently, the bacteria occupied the outer periclinal walls of epidermal cells and stomata. The penetration into the shoot occurred passively through stoma aperture followed by the endophytic establishment on the substomatal chambers and spread to the intercellular spaces of spongy chlorenchyma. After 21 days of inoculation, bacterial biofilm were seen at the root hair base and on epidermal cell wall surface of root and leaf, also confirming the epiphytic nature of H. seropedicae.

    To evaluate a hybrid technique involving GreenLight 120W HPS vapor incision tissue removal in prostate glands > 80 cc. Vapor incision technique (VIT) was performed in 25 consecutive men with a prostate > 80 cc by a single surgeon from May 2010 until September 2010. VIT involved adenoma incisions at 5 and 7-o'clock positions followed by 3, 9 and 12 o'clock down to the surgical capsule. Side-fire vaporization along the capsule excised transurethral resection of the prostate (TURP) like tissue strips for later retrieval. Functional evaluations were performed at 1 and 3 months. Outcomes and complications were compared retrospectively to baseline and a size matched- cohort of 25 men who previously underwent standard vaporization-only photoselective vaporization prostatectomy (PVP). The VIT and control subgroups were comparable. Mean laser time, operative time and energy usage were reduced in the VIT group compared to controls (35 min versus 48 min; 63 min versus 80 min; and 227 k versus 325 kJ respectively; all p 80 cc. VIT appears to be more time-efficient, consumes less energy and obtains tissue for pathological evaluation. Further follow up is required to assess the durability of GreenLight HPS-VIT to PVP vaporization-only for large prostate glands.

    The present experimental work describes the use of a novel protein encapsulation method to achieve protection of the biological factor during the microencapsulation procedure. With this aim, the protein is included in poly(lactic-co-glycolic acid) (PLGA) microspheres without any preliminary manipulation, in contrast to the traditional S/O/W (solid-in-oil-in-water) method where the bioactive substance is first dissolved and then freeze-dried in the presence of lyoprotectors. Furthermore, the presented technique involves the use of an oily additive, vitamin E (Vit E), useful from a technological point of view, by promoting additional protein protection and also from a pharmacological point of view, because of its antioxidant and antiproliferative properties. Application of this microencapsulation technique has been performed for GDNF (glial cell line-derived neurotrophic factor) designed for the treatment of optic nerve degenerative diseases, such as glaucoma, the second leading cause of blindness in the western world. The protein was released in vitro in its bioactive form for more than three months, demonstrated by the survival of their potential target cells (photoreceptors and retinal ganglion cells (RGC)). Moreover, the intravitreal injection of GDNF/Vit E PLGA microspheres in an experimental animal model of glaucoma significantly increased RGC survival compared with GDNF, Vit E or blank microspheres (p<0.01). This effect was present for at least eleven weeks, which suggests that the formulation prepared may be clinically useful as a neuroprotective tool in the treatment of glaucomatous optic neuropathy.

    Full Text Available The prevalence and age distribution of Epstein-Barr virus infection varies in different populations and there is little information about the epidemiology of this infection in Brazil. We studied the prevalence of EBV antibodies in a sample of 283 children and adolescents between 1 and 21 years old. The sample was taken from two neighborhoods in Vitória (capital city of Espirito Santo, Brazil. The São Pedro (SP neighborhood represented an area with lower socioeconomic status and the Praias (P neighborhood represented an area with higher SES. Anti-VCA (Virus Capsid Antigen antibodies were detected by ELISA and anti-EBNA (Epstein-Barr Nuclear Antigen antibodies were detected by an anti-complement immunofluorescence method, both using commercial kits. The results showed an overall prevalence rates of anti-VCA and anti-EBNA of 71% and 54% respectively. The prevalence for both anti-EBV antibodies was higher and probably the infection occurred earlier in the SP neighborhood. Among the various socioeconomic factors studied only low family income and maternal education level were significantly correlated with a higher frequency of positive serology for anti-VCA. These results demonstrate that there is a high prevalence of EBV antibodies in children and adolescents living in Vitória, that occurs more frequently at a younger age in children from families with low socioeconomic status. In addition, the results demonstrate an intermediate age distribution pattern between those reported in developed and underdeveloped countries.

    The community health agent (CHA) has a singular role as a "link" between the community and the health service. The main purpose of this descriptive/qualitative study is to evaluate the production of the CHA work processes in the Family Health Strategy in the county of Vitória (ES, Brazil). The research was developed in the health region of Maruípe, a district in the county of Vitória. The researchers invited 14 CHAs to use a half structured interview based on a guide script containing 24 questions. The process of work in health was considered as "a prevention and promotion of health", and the domiciliary visits were considered as being an everyday basic activity. The CHAs withhold several interpretations concerning to the work process and associated to the concept of unit the team has. It is also possible to notice a kind of idealism of the competences concerning to the CHA work, thus, causing a feeling of impotence and limitation when facing the challenges imposed by it. It is possible to conclude that the CHA needs tools and abilities that overcome their technical knowledge in order to act in a social scope and also to deal with the health needs of each user.

    Full Text Available El vitíligo es un desorden de la pigmentación que tiene una incidencia entre el 0,5 y 3 % en la población mundial. Se caracteriza por una despigmentación de la piel provocada por la presencia de melanocitos afuncionales en la epidermis. Cuando ocurren eventos desencadenantes del estrés oxidativo, las concentraciones de peróxido de hidrógeno se incrementan ostensiblemente en melanocitos y queratinocitos. Los queratinocitos actúan como fuente de especies reactivas de oxígeno y transfieren a los melanocitos grandes cantidades de peróxido de hidrógeno. Evidencias experimentales han demostrado que como consecuencias de las altas concentraciones de peróxido de hidrógeno en la epidermis de pacientes con vitíligo, se afectan las concentraciones de butirilcolinesterasa y acetilcolineterasa, la actividad enzimática en el ciclo de las 6HB4, los péptidos derivados de proopiomelanocortinas y las proteínas del estrés entre otros muchos eventos. Todos estos eventos, tras una situación precipitante sobre un individuo genéticamente predispuesto, podrían promover cambios en la pigmentación de la piel que lo conducen, en última instancia, al vitíligo.Vitiligo is a pigmentation disorder with an incidence between the 0.5 and the 3 % at worldwide. It is characterized by a skin depigmentation provoked by presence of dysfunctional melanocytes in epidermis.

    This study aimed to analyze the prevalence of negative self-rated health and associated factors in the quilombola community (descendants of escaped slaves) in Vitória da Conquista, Bahia State, Brazil. A household survey was conducted with 797 adults in 2011. Data on self-rated health, socioeconomic and demographic characteristics, lifestyle, social support, health status, and access to health services were obtained through questionnaires. Multivariate logistic regression analysis was performed, adjusted for sex and age. Prevalence of negative self-rated health was 12.5%. After statistical modeling, the following variables remained associated with self-rated health: skin color, schooling, adequate consumption of fruits and vegetables, chronic illness, physical limitations, and at least one medical visit in the previous 12 months. Self-rated health was associated with socioeconomic/demographic dimensions, lifestyle, social support, and health status.

    Full Text Available This study aimed to determine the benthic invertebrates found in the rocky substrate in seasonal periods in Rio Palmital, União da Vitória, Parana, Brazil, characterizing the trophic functional groups (collectors, collectors-gatherers, collectors-filterers, shredders, predators and scrapers. Sampling was carried out during the dry (June/July-2011 and rainy (November/December-2011 seasons. The data indicate that the functional group of collectors was the most frequent. The results suggest that there are influences of the disturbances caused by precipitation on the invertebrate fauna during the rainy season, and certain trophic species found may be related to the presence of organic matter as a food source in the diet of invertebrates present there.

    Full Text Available Entre os fatores que interferem na composição e na qualidade do vinho, destaca-se a safra vitícola, com suas variações climáticas. Com este objetivo, avaliou-se o efeito das safras de 1999, 2000 e 2001 na composição da uva, do mosto e do vinho Isabel da Serra Gaúcha. Nesse sentido, foram selecionados vinte e dois produtores de uva Isabel de onze municípios dessa região. Por ocasião da maturação, para as avaliações da uva e do mosto e a elaboração das microvinificações, foram colhidos 60kg de uva de cada viticultor. A safra vitícola interferiu significativamente no peso do cacho e da baga, mas não alterou a relação peso da ráquis/peso do cacho. No mosto, observaram-se diferenças em todas as variáveis, exceto para a relação degreesBrix/acidez total. No vinho, teve efeito na maior parte das variáveis avaliadas, com exceção aos cátions K, Mn, Cu e Rb. Em geral, a safra de 1999 foi a melhor, pois apresentou parâmetros mais adequados de acidez total, extrato seco, extrato seco reduzido, alcalinidade das cinzas, taninos, antocianinas e glicerol, variáveis essas que determinam a estrutura e a cor dos vinhos, importantes fatores para sua qualidade.

    The VI-Ts diagram determined by the scatter points of the vegetation index (VI) and surface temperature (Ts) has been widely applied in land surface studies. In the VI-Ts diagram, dry point is defined as a pixel with maximum Ts and minimum VI, while wet point is defined as a pixel with minimum Ts and maximum VI. If both dry and wet points can be obtained simultaneously, a triangular VI-Ts diagram can be readily defined. However, traditional methods cannot define an ideal VI-Ts diagram if there are no full ranges of land surface moisture and VI, such as during rainy season or in a period with a narrow VI range. In this study, a new method was proposed to define the VI-Ts diagram based on the subpixel vegetation and soil information, which was independent of the full ranges of land surface moisture and VI. In this method, a simple approach was firstly proposed to decompose Ts of a given pixel into two components, the surface temperatures of soil (T soil ) and vegetation (T veg ), by means of Ts and VI information of neighboring pixels. The minimum T veg and maximum T soil were then used to determine the wet and dry points respectively within a given sampling window. This method was tested over a 30 km × 30 km semiarid agricultural area in the North China Plain through 2003 using Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) and MODerate-resolution Imaging Spectroradiometer (MODIS) data. The wet and dry points obtained from our proposed method and from a traditional method were compared with those obtained from ground data within the sampling window with the 30 km × 30 km size. Results show that T soil and T veg can be obtained with acceptable accuracies, and that our proposed method can define reasonable VI-Ts diagrams over a semiarid agricultural region throughout the whole year, even for both cases of rainy season and narrow range of VI.

    Full Text Available This research aims to investigate how information is transmited in family farms, and how the use of information can help to improve agricultural productivity, specially with technical improvements in cassava production in rural areas, such as Vitória de Santo Antão / PE, in order to identify the constraints in the transmission of information reported by rural workers, as much as present rural workers¿ profile and evaluate the competitive advantage of the use of information for productivity of cassava based on productivity indicators. The analyses covered a sample of 15 producers in a universe of 24 farmers participating in the project coordinated by SNE. Questionnaires were addressed to workers and technicals, as well as the technique of systematic observation in order to know the methodology used in technical areas. The results revealed that the limiting process of transmitting information to farmers are due mainly to the poor education of farmers, the lack of appropriate technology due to limited resources, the resistance to changings and lack of human and financial assistance for the training of producers.

    Full Text Available Seamounts are considered important sources of biodiversity and minerals. However, their biodiversity and health status are not well understood; therefore, potential conservation problems are unknown. The mesophotic reefs of the Vitória-Trindade Seamount Chain (VTC were investigated via benthic community and fish surveys, metagenomic and water chemistry analyses, and water microbial abundance estimations. The VTC is a mosaic of reef systems and includes fleshy algae dominated rhodolith beds, crustose coralline algae (CCA reefs, and turf algae dominated rocky reefs of varying health levels. Macro-carnivores and larger fish presented higher biomass at the CCA reefs (4.4 kg per frame than in the rhodolith beds and rocky reefs (0.0 to 0.1 kg per frame. A larger number of metagenomic sequences identified as primary producers (e.g., Chlorophyta and Streptophyta were found at the CCA reefs. However, the rocky reefs contained more diseased corals (>90% than the CCA reefs (~40% and rhodolith beds (~10%. Metagenomic analyses indicated a heterotrophic and fast-growing microbiome in rocky reef corals that may possibly lead to unhealthy conditions possibly enhanced by environmental features (e.g. light stress and high loads of labile dissolved organic carbon. VTC mounts represent important hotspots of biodiversity that deserve further conservation actions.

    Full Text Available The rapid environmental modifications resulting from the uncontrolled advance of different human activities constitute a constant threat to biodiversity and may be related to the level of understanding and perception of society in face of the environmental problem. Thus, the present study aimed to identify perceptions of the terms “environment” and “environmental education” by teachers of the Federal School of Agrotechology in Vitória, Santo Antão, as well as knowledge about their environmental practices in the classroom. The results indicated that the teacher’s perception of the terms “environment” and “environmental education” favored basically the traditional trend and a naturalistic viewpoint, relating the terms only to natural aspects. Based on this survey, it was possible to identify the necessity of intense work with the teachers in order to sensitize them to pertinent environmental questions. From this, a list of points was raised for the constitution of a possible Program of Environmental Education at the school, directed not only towards the acquisition of knowledge on environmental subjects, but also towards the provision of an essential strategical tool so that the teachers could become multiplying agents while in the classroom.

Entrevistas realizadas com quatro grupos de dez moradores no município de Vitória (ES alertam para esse risco. Para a análise dos depoimentos, foi aplicada metodologia qualitativa, empregando-se a estratégia do Discurso do Sujeito Coletivo. Os discursos apontam para a falta de conhecimento dos usuários acerca da manutenção correta do reservatório e filtro domiciliares de água, para a desconfiança da qualidade da água recebida do sistema público e a falta de um canal de comunicação efetivo entre a população, o serviço de saneamento e as instituições de saúde pública locais. A pesquisa mostra a necessidade de se reverem as formas de comunicação com a população atualmente adotadas por essas instituições.Wrong domiciliary habits with regard to the management of water consumption may affect the health of its users. Interviews conducted with four groups of ten residents in Vitória (ES, Brazil, point out the risk. For the analysis of testimonials, the qualitative methodology was applied, as employing the strategy of Collective Subject Discourse. The discourses showed the lack of knowledge of the users about the proper maintenance of the reservoir and filter household water, the mistrust on the quality of water received from the public system and the lack of an effective communication channel between the population, the water supply services and the local institutions of public health. This research shows the need to review the types of information provided to the population currently adopted by these institutions.

    Full Text Available O texto trata da fragmentação sócio-espacial na cidade a partir da teoria dos dois circuitos urbanos de Milton Santos e de reflexões diversas sobre a segregação e a fragmentação. Busca compreender o acesso às redes elétricas como reveladoras desse processo nos bairros da Penha e da Fonte Grande no município de Vitória – ES. A infra-estrutura da rede elétrica nesses lugares é precária, bem como o consumo médio das residências relativamente elevado em função das instalações ruins e dos inúmeros eletrodomésticos possuídos pelas famílias. As tarifas em relação à renda média dos habitantes são relativamente elevadas: os valores pagos por kWh para as residências são iguais para todas as classes sociais e bem superiores àqueles da grande indústria. O meio encontrado para se suprir em eletricidade, por uma parte mais pobre dos habitantes, é o seu uso ilícito. Há uma criminalização de parcelas das populações incitadas ao consumo, mas sem meios para arcar com os custos e que acabam lançando mão de expedientes ilegais para se suprir em eletricidade. Isso reforça os processos de fragmentação territorial e de desfiliação das populações que ali vivem.

    Full Text Available OBJECTIVE: To determine the prevalence of metabolic syndrome and related factors in bank employees in the city of Vitória/ES, Brazil. METHODS: This was a cross-sectional study that included 521 working men and women >20 years of age. Sociodemographic, lifestyle, anthropometric, biochemical, and hemodynamic characteristics were collected. Metabolic syndrome was diagnosed using the criteria of the National Cholesterol Education Program-ATPIII and the International Diabetes Federation. A logistic regression model was used to calculate the crude and adjusted OR of the variables, and the statistical level of significance was set at 5.0%. RESULTS: We identified 86 (17.2% and 113 (22.6% subjects with metabolic syndrome according to the criteria of the National Cholesterol Education Program-ATPIII and the International Diabetes Federation, respectively. The risk of developing metabolic syndrome was higher in individuals with a high school education (OR 2.6 [CI95%, 1.1-6.1]. In overweight and obese subjects, the risks were also higher (OR 12.6 [CI95%, 4.8-33.2, p = 0.000] and OR 43.7% [CI95%, 16.1-118.9, p = 0.000], respectively. CONCLUSION: A large number of bank employees have metabolic syndrome, which can be associated with an increased risk of developing cardiovascular disease. Individuals who had college degrees had a higher prevalence of metabolic syndrome; this finding can be explained by the high rates of overweight and obesity found in subjects with college and graduate school educations.

    Full Text Available A aclimatação de mudas de abacaxizeiro propagadas por cultura in vitro é um processo lento. A promoção do crescimento radicular pelo uso de ácidos húmicos pode ser útil durante esse processo. O objetivo deste trabalho foi avaliar o desempenho do abacaxizeiro 'Vitória' propagado por cultura de tecidos em resposta à aplicação de diferentes doses de ácidos húmicos isolados de vermicomposto e de torta de filtro durante o período de aclimatação em casa de vegetação. Foram avaliadas as características anatômicas da lâmina foliar, o teor de pigmentos fotossintéticos, o crescimento da parte aérea e do sistema radicular, e o conteúdo de nutrientes foliares. Os resultados mostraram incrementos no crescimento e desenvolvimento da parte aérea e do sistema radicular com a aplicação de ácidos húmicos, bem como acúmulo significativo de N, P, K, Ca e Mg e aumento na relação clorofila a/clorofila b. A promoção do crescimento das mudas durante o período de aclimatação, em resposta à aplicação de ácidos húmicos, pode melhorar a adaptação do abacaxizeiro ao ambiente ex vitro.The acclimatization of pineapple plantlets propagated by plant tissue culture is slow. The intensification of root growth by the use of humic acids may be useful during this process. The aim of this study was to evaluate the greenhouse acclimatization of 'Vitória' pineapple propagated by plant tissue culture in response to different doses of humic acids isolated from vermicompost and filter cake. Leaf anatomy, photosynthetic pigment content, shoot and root growth, and leaf nutrients were evaluated.

    Full Text Available OBJETIVO: Descrever a prevalência de infecção por HIV em gestantes e a taxa de transmissão vertical, segundo o perfil socioeconômico dos bairros de residência das mães. MÉTODOS: Estudo ecológico exploratório utilizando a base de dados do Sistema de Informação de Agravos de Notificação de gestantes HIV-positivas e aids em crianças notificadas entre 2000 e 2006 em Vitória, ES. Para análise das informações socioeconômicas foi utilizado o Índice de Qualidade Urbana. A prevalência de HIV em gestantes e a taxa de transmissão vertical foram calculadas. A distribuição espacial dos casos foi realizada no programa Terraview 3.2.0. Para verificar a associação entre a qualidade urbana e a prevalência de HIV em gestantes utilizou-se o modelo de regressão de Poisson. RESULTADOS: Um total de 137 gestantes e 14 crianças infectadas por transmissão vertical foi notificado no período. Sete crianças correspondiam a mães HIV-positivas sem notificação de caso no período analisado. A prevalência de infecção em gestantes no período foi de 0,44% e a taxa de transmissão vertical foi de 9,7%. CONCLUSÕES: A prevalência de infecção por HIV em gestantes e a transmissão vertical associam-se à qualidade urbana do bairro de residência, indicando que os bairros com menor qualidade urbana devem ser priorizados quanto às ações para redução da transmissão vertical.

    Full Text Available O objetivo deste artigo é analisar o resultado primário fiscal dos municípios brasileiros entre 1999 e 2007, aplicando a metodologia de viés de seleção para dados em painel proposto por Wooldridge (1995. Mais especificamente, assume-se que a ocorrência de superávits e déficits fiscais não deve ser tomada como um evento puramente aleatório e, alternativamente, assume-se a existência de um primeiro estágio que determina a ocorrência de um superávit ou de um déficit fiscal. Os resultados corrigidos para a presença do viés amostral indicam que saldos fiscais positivos e negativos são parcialmente influenciados pelas características fiscais dos municípios, bem como pela estrutura demográfica da população. Contudo, suas características políticas pouco influenciam o resultado fiscal.

The Aquavit-2 campaign provided an excellent opportunity to evaluate both axes of the HWV instrument under a controlled laboratory setting, and to compare with other state-of-the-art hygrometers within the international community, many of which have contributed substantially to UT/LS water vapor measurements for several decades. Laboratory efforts, however, are limited by their ability to replicate the unique sampling conditions, e.g., temperature, pressure, flow, chemistry, of the flight environment. Differences in instrument implementation between the laboratory and flight environment must also be considered. The SEAC4RS mission provides an excellent opportunity to further evaluate the performance of the dual-axis instrument in situ. Sampling with the Ly-α and HHH instruments on the ER-2 in the proximity of Microwave Limb Sounder (MLS) overpasses and coordinated launches of the Cryogenic Frostpoint Hygrometer (CFH) promises a statistically significant and rich dataset for comparison.

    Full Text Available RESUMOA obtenção de correlações adequadas entre características fitotécnicas, como massa de folha 'D' e diâmetro do talo com produção do abacaxizeiro podem predizer com exatidão o período adequado para indução floral e obtenção de máxima produtividade. Tais informações ainda são consideradas escassas para a cultivar 'Vitória'. Neste sentido, objetivou-se com este estudo correlacionar e relacionar características fitotécnicas e nutricionais com a produção do abacaxizeiro 'Vitória' irrigado na região Norte do Estado de Minas Gerais. Para tanto, foram coletadas, aleatoriamente, 75 plantas durante o período de indução floral de lavoura irrigada com pivô central. Após a coleta, as partes das plantas foram compartimentalizadas em folhas D, folhas totais, talo, fruto e raízes para estimativa da massa da matéria fresca e seca. Além destes, foram estimados o diâmetro do talo, comprimento da folha D, teor de macronutrientes e micronutrientes na folha D e índice de colheita. Por meio da análise de variância observou-se correlação significativa entre a maioria das características e a produção de frutos, destacando-se as maiores correlações positivas entre a massa da matéria fresca e seca da folha D (fresca r = 0,82; seca r = 0,84, diâmetro do talo (r = 0,82 e diâmetro do fruto (r = 0,93 com a massa dos frutos. Para obtenção da massa do fruto igual ou superior a 1,2 kg planta-1 sugeriu-se a indução floral de plantas de abacaxizeiro 'Vitória' com massa mínima de 70 g de matéria fresca de folha D ou de plantas com diâmetro do talo mínimo de 8,5 cm.

    Full Text Available This paper aims to carry out a comparative evaluation of the populations of Loxosceles spp. (brown spiders found in the municipal district of União da Vitória, Paraná. Natural and anthropic substrata were inspected in the intra- and peridomicile in urban and rural areas. Loxosceles intermedia Mello-Leitão, 1934 was present in 57% of the residences. It was not randomly distributed among the neighborhoods or the substrata and was less frequent than other species of spiders found in the same habitats. The few records of loxoscelism may be due to the small population of brown spiders in domestic habitats. Notwithstanding the seemingly adequate climatic and substratic conditions, the population growth of L. intermedia might be limited by the presence of other species inside and around houses.

    Full Text Available In vitro propagation of pineapple produces uniform and disease-free plantlets, but requires a long period of acclimatization before transplanting to the field. Quicker adaptation to the ex vitro environment and growth acceleration of pineapple plantlets are prerequisites for the production of a greater amount of vigorous, well-rooted planting material. The combination of humic acids and endophytic bacteria could be a useful technological approach to reduce the critical period of acclimatization. The aim of this study was to evaluate the initial performance of tissue-cultured pineapple variety Vitória in response to application of humic acids isolated from vermicompost and plant growth-promoting bacteria (Burkholderia spp. during greenhouse acclimatization. The basal leaf axils were treated with humic acids while roots were immersed in bacterial medium. Humic acids and bacteria application improved shoot growth (14 and 102 %, respectively, compared with the control; the effect of the combined treatment was most pronounced (147 %. Likewise, humic acids increased root growth by 50 %, bacteria by 81 % and the combined treatment by 105 %. Inoculation was found to significantly increase the accumulation of N (115 %, P (112 % and K (69 % in pineapple leaves. Pineapple growth was influenced by inoculation with Burkholderia spp., and further improved in combination with humic acids, resulting in higher shoot and root biomass as well as nutrient contents (N 132 %, P 131 %, K 80 % than in uninoculated plantlets. The stability and increased consistency of the host plant response to bacterization in the presence of humic substances indicate a promising biotechnological tool to improve growth and adaptation of pineapple plantlets to the ex vitro environment.A propagação in vitro de abacaxizeiro produz mudas uniformes e sadias, mas exige longo período de aclimatização antes da transferência para o campo.

    The scope of the study was to assess moderate and excessive alcohol consumption and associated factors among residents of Quilombola Communities in Vitória da Conquista in the State of Bahia. It involved a cross-sectional study among 750 individuals aged ≥ 18 years interviewed in 2011 using an adapted version of the National Survey of Health Questionnaire. Alcohol consumption was classified into abstemious, moderate and heavy drinking categories and was analyzed using the multinomial regression model. Consumption was observed among 41.5% of participants (95% CI [37.8, 44.98]); 10.7% being identified in the excessive consumption category and 30.8% in the moderate consumption category. Moderate consumption was inversely associated with age and is more common among whites and mulattoes, the better educated, the gainfully employed and among smokers. Heavy consumption increased with level of education, being more prevalent among those who had at least 8 years of schooling, smokers and the gainfully employed. The study shows that in these communities there are differences in the sociodemographic characteristics among the profiles of alcohol drinkers and these differences should be taken into account when drawing up proposals for the promotion of healthy habits.

    The scope of this paper was to investigate the relationship between the nutritional status and the motor skills of the elderly registered in the Family Health Program in the urban area of Vitória de Santo Antão in the State of Pernambuco, by means of a transversal epistemological descriptive-analytical field study. The participants of this survey were 235 elders, both male and female of 60-years-old and over registered in the family health program in the urban area of the city. The nutritional status was evaluated by the body mass index and the circumference of the calf. Four motor tests were used to evaluate motor performance: Time Up&Go, Tinetti's Index, Functional Reach and Unipodal Support. The associations were checked using Spearman's correlation. The association of the nutritional status with the motor tests was statistically significant among males* or females**: (Time Up&Go rho = 0.290* / 350**; Functional Reach rho = 0.232* / 352**; Tinetti's Index rho = 243* / 363** and Unipodal Support rho = 221* / 475**. The evaluation of the results revealed an association between nutritional status and functional capacity of the elders no matter what gender; with obesity being a limiting nutritional condition to adequate performance in the tests.

    Family Health is a re-orientation strategy of the assistance model. One of its guiding principles is the establishment of a link between the health teams and the SUS users. The purpose of this research is to evaluate user access to the Family Health Unit (FHU) and the local problems faced. It is an exploratory, qualitative research, developed at the FHU Resistencia of São Pedro, located in the Greater Vitória, Espírito Santo State, with data collected individually through a semi-structured survey. It was found that the main needs of the population are incorporated in the services provided by the FHU, and the users face many difficulties with access. The main criticism is related to access to the specialized services. The majority of the participants of the survey showed satisfaction with the access to the services, and were not intimidated to express the difficulties faced. The work developed by the Family Heath Strategy (FHS) at FHU Resistência has been contributing to the improvement of the quality of the services offered by FHS to the users served, although many problems have been identified, which demonstrates the great challenge in redefining the assistance model, as proposed by this public policy.

    Dengue presents a wide clinical spectrum of signs and symptoms, with characteristics of the host potentially influencing the disease evolution. Therefore, the purpose of this study was to evaluate the influence of gender and age on dengue clinical outcomes in a recent outbreak situation in Brazil, applying a cross-sectional design and including 6703 dengue cases with laboratory confirmation, occurring in Vitória, Espírito Santo State, Brazil, between 2007 and 2013. Data were obtained from the Information System for Notifiable Diseases. Overall, 11·3% of the sample presented with severe dengue, which affected 13·0% of males, 10·0% of females, 8·8% of children, 12·5% of adolescents, 10·5% of adults and 15·5% of the elderly. Age was higher in the severe dengue group (P = 0·03). Severe dengue was associated with males and the elderly (P dengue cases, taking into consideration host factors like age. These findings also suggest the elderly and children as priority groups for immunization in a future implementation of a vaccine.

    The Caenorhabditis elegans vitellogenin genes are transcribed in the intestine of adult hermaphrodites but not of males. A 44-bp region from the vit-2 gene promoter is able largely to reconstitute this tissue-, stage- and sex-specific-expression. This "enhancer" contains a binding site for the DM-domain factor MAB-3, the male-specific repressor of vitellogenesis, as well as an activator site that we show is the direct target of the intestinal GATA factor ELT-2. We further show that the enhancer is directly activated by the winged-helix/forkhead-factor FKH-9, (whose gene has been shown by others to be a direct target of DAF-16), by an unknown activator binding to the MAB-3 site, and by the full C. elegans TGF-β/Sma/Mab pathway acting within the intestine. The vit-2 gene has been shown by others to be repressed by the daf-2/daf-16 insulin signaling pathway, which so strongly influences aging and longevity in C. elegans. We show that the activity of the 44 bp vit-2 enhancer is abolished by loss of daf-2 but is restored by simultaneous loss of daf-16. DAF-2 acts from outside of the intestine but DAF-16 acts both from outside of the intestine and from within the intestine where it binds directly to the same non-canonical target site that interacts with FKH-9. Activity of the 44 bp vit-2 enhancer is also inhibited by loss of the germline, in a manner that is only weakly influenced by DAF-16 but that is strongly influenced by KRI-1, a key downstream effector in the pathway by which germline loss increases C. elegans lifespan. The complex behavior of this enhancer presumably allows vitellogenin gene transcription to adjust to demands of body size, germline proliferation and nutritional state but we suggest that the apparent involvement of this enhancer in aging and longevity "pathways" could be incidental.

    Full Text Available Sexually transmitted infections during pregnancy pose a major risk to the fetus due to vertical transmission. The study's objective was to determine the prevalence of HIV, syphilis, hepatitis B and C, and HTLV-I/II infection among low-income postpartum and pregnant women treated in Greater Metropolitan Vitória, Espírito Santo State, Brazil, and the risk factors associated with these infections. A cross-sectional study was conducted from February to October 1999 assessing postpartum and pregnant women from the maternity ward of the Vitória Mercy Hospital and the Carapina Outpatient Referral Unit in the Municipality of Serra, respectively. Patients were systematically interviewed and had blood samples drawn for serological tests (HIV 1&2, VDRL, HbsAg, anti-HCV, and HTLV-I/II. A total of 534 patients (332 postpartum and 202 pregnant women were assessed. Seroprevalence rates for the target infections in postpartum and pregnant women and the overall sample were as follows, respectively: HIV 0.9%, 0%, and 0.6%; syphilis 2.1%, 3.6%, and 2.7%; HBV 1.2%, 1%, and 1.1%; HCV 1.8%, 0.6%, and 1.4%; and HTLV-I/II 1.7%, 0.6%, and 1.3%. Factors associated with the various infections are presented and analyzed in light of other research findings from the literature.A ocorrência de doenças sexualmente transmissíveis durante a gravidez representa risco aumentado de morbidade e mortalidade para o feto e neonato em virtude da transmissão vertical.

    Full Text Available Introdução: A poluição do ar é um importante fator ambiental relacionado a doenças crônicas não transmissíveis, como doenças cardiovasculares e respiratórias. Essa relação torna-se importante em cidades com alta atividade industrial, como Vitória/ES. Esta pesquisa utilizou três revisões sistemáticas (RSs distintas para avaliar a epidemiologia das doenças cardiovasculares (RS1, a epidemiologia das doenças respiratórias (RS2 e a associação entre poluição do ar e doenças cardiorrespiratórias (RS3 na cidade de Vitória. Métodos: A busca bibliográfica considerou três bases de dados (PubMed, Scopus e LILACS. Foi estabelecida uma quantidade mínima de três estudos para a condução de metanálises. A heterogeneidade de cada análise foi calculada pelo índice I2 . Resultados: A busca bibliográfica resultou em 1.205 registros, dos quais 27 foram incluídos – 17 na RS1, cinco na RS2 e cinco na RS3. Apenas dois desfechos puderam ser avaliados por meio de metanálises: prevalência de hipertensão e prevalência de asma em crianças. Estima-se uma prevalência de 34% (IC95%: 24-45 de hipertensão e de 12% (IC95%: 1-32 de asma em crianças. Os poluentes mais avaliados foram MP10 e SO2 , para os quais não se pôde realizar metanálises. Todas as análises apresentaram baixo número de registros incluídos e alta heterogeneidade. Conclusão: Há poucos dados disponíveis sobre a associação de doenças cardiorrespiratórias e poluição ambiental em Vitória. A heterogeneidade, a diversidade de desfechos e a baixa quantidade de estudos impediram a condução de análises mais profundas e limitaram o poder de síntese e conclusão dessas revisões, impossibilitando uma avaliação adequada dos objetivos propostos. São necessários mais estudos epidemiológicos com amostras de grande porte e representativas para que se tenha resultados conclusivos sobre a relação entre poluição ambiental e doenças cardiorrespirat

    Full Text Available This work evaluated the physicochemical composition of 171 red Brazilian wines from the 2006 vintage, which were represented by 21 varietals. These wines were produced by 58 Brazilian wineries in different regions of the country, with latitudes varying from 9º to 31º South. Physicochemical wine analysis was performed in the same year and discrimination in the viticultural regions, varietal wines, and wineries was performed by means of the principal component analysis (PCA. The main results show that wines from São Joaquim had higher values of A420, A520, A620, color intensity, total phenolic compounds, anthocyanins, and dry extracts, while those from Toledo had lower values of these variables; those from Vale do São Francisco had higher values of potassium, pH, density, and volatile acidity; from Serra do Nordeste A, they had higher titratable acidity; and from Planalto Superior B, higher hue. Regarding the varietal wines, PCA mainly discriminated the wines produced from the varieties Ancellotta, Teroldego, Egiodola, Refosco, Marselan, Cabernet Sauvignon, Pinotage, Pinot Noir, Malbec, Arinarnoa, Barbera, and Alfrocheiro. In relation to wineries, twenty two of them were discriminated by their higher values of some variables, i.e., three were characterized by color intensity; three by hue; eight by alcohol content; six by potassium, dry extract, density, and pH; and two by titratablel acidity.O trabalho avaliou a composição físico-química de 171 vinhos tintos brasileiros elaborados na safra de 2006, representados por 21 varietais.

    Los residuos sólidos generados por las diversas actividades urbanas se presentan como una de las principales preocupaciones de la sociedad, a la vista de las consecuencias perjudiciales que pueden causar al medio ambiente cuando no se manejan correctamente. Hoy en día, es muy común ver a los grandes volúmenes de residuos sólidos en terrenos baldíos, los cursos de agua e incluso lugares públicos como aceras y plazas. El artículo tiene como objetivo realizar un diagnóstico sobre la eliminación incorrecta de los residuos sólidos en el barrio de Redenção, municipio de Vitória de Santo Antão-PE, ya partir de ese diagnóstico hacen propuestas para la educación ambiental y un sistema de recogida selectiva que hacen posible la correcta gestión de los residuos sólidos allí. Para ello, se realizaron visitas a la zona de la Redenção, hicieron registros fotográficos y descriptivos para destacar los puntos críticos de los residuos, el momento de la recogida convencional, los principales generadores de residuos y la disposición inadecuada de los residuos en esa comunidad. Los principales problemas observados fueron: construcción deposición de residuos en las carreteras locales, eliminación de residuos domésticos en los canales de agua de lluvia, los animales vagan cerca de acumulación de puntos críticos, la eliminación de desechos peligrosos terrenos baldíos. Frente a este diagnóstico se propusieron acciones de educación ambiental que implican comerciantes, escuelas y guarderías, líderes comunitarios y otros residentes. Teniendo en cuenta lo anterior, se puede concluir que existe una urgencia en extensión a la comunidad y el gobierno local, de modo que proporciona una mejor calidad de vida de la población y hacer cumplir las que determinan las políticas federales y estatales de los residuos sólidos.

    The scope of this article was to present the methodology, preliminary descriptive results and the reliability of the instruments used in the COMQUISTA Project. It involved a cross-sectional study with adults (>18 years) and children (up to 5 years old) of Quilombola communities in Vitória da Conquista, Bahia. Data collection consisted of individual and household interviews, anthropometric and blood pressure measurements. A semi-structured questionnaire adapted from the Brazilian National Health Survey (PNS) was used and the interviews were conducted using handheld computers. 397 housing units were visited and 797 adults and 130 children were interviewed. The demographic profile of the Quilombolas was similar to the Brazilian population with respect to sex and age, however, they had precarious access to basic sanitation and a low socioeconomic status. The analysis of reliability revealed the adequacy of strategies adopted for quality assurance and control in the study. The methodology used was considered adequate to achieve the objectives and can be used in other populations. The results indicate the need for implementing strategies to improve the quality of life and reduce the degree of vulnerability of the Quilombolas.

No total, a nossa amostra foi constituída por 95 jogos de rugby pertencentes ao Torneio Super12. As variáveis a serem analisadas foram subdivididas em variáveis de ações do jogo (e.g., passes realizados, penalidades concedidas, recuperações de bola, etc. e variáveis de resultado (e.g., "trys", conversões, chutes de penalidade. Os procedimentos estatísticos utilizados: a análise exploratória inicial; b análise de "clusters"; e c análise discriminante, permitiram associar jogos entre si, tendo sido definido por nós como critério de agrupamento a diferença na pontuação final dos jogos. Os resultados permitiram concluir que o maior contributo para o resultado final dos jogos equilibrados resultou da marcação de "trys" (2,9 ± 1,4.

    The study aimed to estimate the prevalence of hypertension in members of quilombos (slavedescendant African-Brazilian communities) and to evaluate possible associated factors. A population-based survey included 797 individuals 18 years or older. Hypertension was defined as systolic blood pressure ≥ 140mmHg or diastolic blood pressure ≥ 90mmHg or reported use of antihypertensive medication. We used Poisson regression with robust variance and hierarchical entry of variables. Prevalence of hypertension was 45.4% (95%CI: 41.89-48.85). Factors associated with hypertension were: neighborhood security (distal), age, economic class, education, and physical inactivity (intermediate), and body mass index (proximal). Health promotion is needed in the quilombo communities through action at the individual and population levels. The high prevalence of hypertension highlights the need for broad access to health services for prevention, early diagnosis, and guidelines for adequate management.

    As monitoring of renal function, it is used the estimation of glomerular filtration rate (GFR). This study aimed to estimate the GFR by means of the Cockcroft-Gault equation in hypertensive patients in the Municipality of Vitoria-ES. It is a transversal study of secondary data with 754 hypertensive patients attended in health facilities in 2009. For statistical analysis, there has been used the chi-square test. The female sex, overweight and uncontrolled blood pressure predominated. The average age was 58.18 years (± 13.52) and the serum creatinine (SCr) 0.81 mg / dl (± 0.28). The prevalence of reduced GFR was 19% when from 30 to 59 ml/min and 1.6% when from 29 to 15 ml/min. The prevalence of reduced GFR was 15 times higher in the elderly, 4.93 times higher in those with elevated SCr, 2.19 times in low-weight hypertensives and 1.6 times more prevalent in men. The study showed the importance of monitoring renal function with a view to early intervention and postponement of kidney function loss in hypertensive patients.

After the training, the patient was allowed to choose either a family member or a health care worker as a supervisor. Absolute and relative frequencies were used in descriptive data analysis. RESULTS: A family member supervisor was chosen by 94 patients (96%. The cure rate was 99%. The partner was chosen by 49% of the patients, and other family members were chosen by 28%. The heath care team needed to take over DOT in 3% of the cases. Regular attendance at follow-up appointments was 67%. It was observed that 24% of the problems in this DOT model referred to the family supervisor forgetting to administer the medication or to the patient forgetting to take it; 39% of the patients forgot to take the medication for one day, and 31% forgot to take it for two days. There was change of supervisor in 9% of the sample, medication was lost by the patient sometime during treatment in 9%, and patient drug intolerance occurred in 8%. CONCLUSIONS: DOT supervised by a family member has proven an effective and low-cost technique. However, compliance is not due to one single factor but to the combination of strategies adopted: bus passes; educational measures and especially the individualized approach.

    Full Text Available Literature on childhood friendship is quite diversified, focusing on various aspects (social, emotional and cognitive, etc. revealing the complex nature of the subject. This study aimed at investigating different aspects of friendship in children in order to contribute to the formulation of a theoretical model for understanding friendship as a complex system of relations. Forty children aged seven to ten years, participants of the “Projeto Caminhando Juntos” (Cajun, in the city of Vitoria, were interviewed. This project offers several courses for children and adolescents from six to seventeen years old enrolled in schools in the city of Vitoria and aims to integrate children socially, avoiding them to stay on the streets, promoting physical education, moral and social children from disadvantaged communities. The results refer to friends network (including the best friend, space and time, activities and communication with friends, psychosocial processes (social support, competition, aggression and reconciliation, cognitive and affective processes (perception of friends and relationship and friendship and emotions and the development of friendship. These aspects were discussed in light of their possible integration into a theoretical model of childhood friendship. We conclude that wide theoretical models of friendship and interpersonal relationships are necessary to guide research in the area.

    Full Text Available O objetivo deste trabalho é analisar como a organização do fazer obstétrico motiva uma comunidade de práticas a optar pelo parto humanizado, contribuindo para a mudança dessa prática. A pesquisa foi conduzida por meio da observação, empregando a epistemologia da prática segundo Theodore Schatzki e a análise temática dos dados. Os resultados apontam que diferentes entendimentos acerca do corpo levam à reprodução das práticas obstétricas ou ao esforço em prol da sua mudança. Quando o corpo da mulher é tido enquanto um objeto, a gravidez é um problema a ser resolvido. Por outro lado, quando esse passa a ser um “corpo-pessoa”, não é possível desassociá-lo da mulher. Consequentemente, a gravidez deixa de ser um problema, tornando-se um processo natural e fisiológico que deve ser respeitado, e não solucionado o mais rápido possível. Este trabalho contribui com o campo ao analisar como a mobilização das práticas se altera ao longo do tempo. Além disso, o estudo da obstetrícia revela a centralidade do corpo na performance dessa prática social. Afinal, é o corpo da mulher que entra em trabalho de parto, que dá à luz e que, infelizmente, ainda sofre violência obstétrica. Enfim, é esse o “veículo” que transporta as práticas.

La importancia del follaje en las plantas aumenta cada vez más, pasando de ser una práctica utilizada inicialmente en el control del crecimiento, obtención de rendimientos sostenibles y prevención de plagas y enfermedades; para convertirse en un método integral esencial en busca del mejoramiento de la calidad de los productos cosechados. La industria vinícola de clima frío tropical debe esforzarse por aumentar la calidad de la uva y por ende de sus vinos, a través del manejo de los viñedos frente a las condiciones climáticas de las zonas aptas para el cultivo; pues bajo estas circunstancias, la luz es probablemente el factor ambiental más complejo y variable que actúa sobre las plantas, desempeñando un papel crucial al proporcionar energía para la fotosíntesis y servir como estímulo para el crecimiento y la adquisición de información de calidad.

    Currently, hospital infection is a serious public health problem, and several factors may influence the occurrence of these infections, including the presence of insects, which are carriers of multidrug-resistant bacterial species. The aim of this study was to isolate staphylococci carried by insects in two public hospitals of Vitoria da Conquista, Bahia and to identify the resistance profile, pathogenicity and efficacy of disinfection of the premises. A total of 91 insects were collected in 21 strategic points of these hospitals, and 32 isolated strains of Staphylococcus aureus were isolated. Based on antibiogram and Minimum Inhibitory Concentration results, 95% of these strains were susceptible to oxacillin. These strains were also evaluated for the presence of resistance genes encoding resistance to oxacillin/methicillin by polymerase chain reaction, but the sample was negative for this gene. Pathogenicity tests were performed in vitro biofilm formation induced by glucose, where it was found that eight (27.58%) strains were classified as biofilm producers and 21 (72.4%) as stronger producers. In addition, we performed PCR for their virulence genes: Sea (enterotoxin A), SEB (B), Sec (C), PVL (Panton-Valentine Leukocidin), ClfA (clumping factor A) and Spa (protein A). Of these, Sea, Spa PVL were positive in 7 (21.8%), 2 (6.3%) and 1 (3.1%) samples, respectively. The analysis of cytokine induction in the inflammatory response of J774 macrophages by isolates from the two hospitals did not show statistical difference at the levels of IL-6, TNF-α, IL-1 and IL-10 production. In addition, we verified the antimicrobial activity of disinfecting agents on these strains, quaternary ammonium, 0.5% sodium hypochlorite, 1% sodium hypochlorite, 2% sodium hypochlorite, 2% glutaraldehyde, Lysoform(®), 70% alcohol solution of chlorhexidine digluconate, 2% peracetic acid, and 100% vinegar. Resistance was seen in only for the following two disinfectants: 70% alcohol in 31 (96.8%) samples tested and vinegar in 30 (93.8%) samples. The study demonstrated the presence of resistant and pathogenic organisms conveyed by insects, thus suggesting improvement in efforts to control these vectors. Copyright © 2013 Elsevier Editora Ltda.

    Osteoporotic fractures are important causes of morbidity, mortality, and increased health care costs. However, the risk of osteoporotic fractures can be decreased, with clinical studies supporting the use of calcium and vitamin D supplements to promote bone health. Vitamin D insufficiency is widespread, particularly among postmenopausal women with osteoporosis, and this indicates that dietary intake is suboptimal, even though vitamin D supplements are widely available. We conducted an observational study, using telephone surveys, to estimate vitamin D and calcium intake and the use of prescription osteoporosis medications in Spanish women aged ≥ 50 years with osteoporosis. Among the study participants, mean dietary calcium intake was 1239 mg/day and generally appeared sufficient in terms of the recommended daily intake guidance documents. Participants aged ≥ 75 years had a significantly lower mean dietary calcium intake (988 mg/day), thus one-half were below the level advised by the World Health Organization. Daily calcium intake was also lower in participants who were not taking prescription medications for bone health. Dietary vitamin D intake was 167 IU/day, which is well below both the established target dose (400 IU/day) and the more recent, higher guideline recommended for postmenopausal women (800-1300 IU/day). Dietary vitamin D intake was even lower for participants aged ≥ 75 years (120 IU/day) and was not related to the use of bone health prescription medications. These results support the need for greater promotion of the benefits of higher vitamin D intake in Spanish women with osteoporosis.

    Full Text Available O drama de Josef K., personagem de O processo, de Franz Kafka, põe em movimento uma desenfreada narrativa cuja gênese se origina dos sentimentos de paradoxo e ambiguidade. O absurdo como princípio de escrita consolida-se com a determinação de conceitos como a dessubstancialização da lei e a brutalização moral. A vergonha, imposta pela opressão do meio social, aparece como uma força subjetiva dominante, alçando-se como neutralizadora de possíveis promessas de emancipação que a história pode encontrar nos sistemas políticos respaldados por direitos legais arraigados por um Estado legitimado como suposto bastião da justiça. Este estudo pretende abordar essas questões e delinear os expedientes narrativos pelos quais Kafka desenvolve em sua estética formas de revolta, resignação e derrota.

    Childhood undernutrition may have prenatal origins, and the impact of prenatal interventions on postnatal growth is not well known. We assessed the effects of prenatal multiple micronutrient (MM) supplementation on child growth and cognitive development. In a cluster-randomized controlled trial in rural Bangladesh, prenatal MM supplementation compared with iron-folic acid (IFA) supplementation was examined for its impact on growth assessed longitudinally from birth up to 24 mo of age (n = 8529) and, in a subsample (n = 734), on cognitive function at 24 mo of age by use of the Bayley scales of infant and toddler development-third edition test. Prevalence of stunting at birth [length for age z score (LAZ): cognition, language, and motor performance at 24 mo of age. In this Bangladeshi trial, maternal pre- and postnatal MM supplementation resulted in improvements in LAZ and reduction in stunting through 3 mo of age, but not thereafter and had no impact on cognitive and motor function at 2 y.

    Full Text Available This prospective study evaluated the incidence of Mycobacterium tuberculosis infection among nursing students at the Federal University of Espírito Santo, using the purified protein derivative test. In parallel, we evaluated whether knowledge on tuberculosis transmission mechanisms had any impact on nursing students' attitudes in relation to the risk of tuberculosis infection. The incidence of tuberculin conversion was 10.5% per year (p=0.035, 95% CI = 3.63-17.43, whereas the expected conversion rate in the overall population in Brazil is 0.5% per year. These results indicate nursing students as a group at risk for TB infection. Among the risk factors studied only the use of NIOSH95 masks was associated with protection against infection (RR=0.2. Furthermore there was no statistical difference among students that PPD converted and those who remained negative regarding disease knowledge and the existence of adequate facilities for patient hospitalization.

Paralelamente, avaliamos se o conhecimento sobre mecanismos de transmissão da tuberculose teve algum impacto nas atitudes dos estudantes em relação ao risco de infecção por tuberculose. A incidência da conversão tuberculínica foi de 10,5% ao ano (p=0,035, 95% CI = 3,63 - 17,43, quando a taxa de conversão para a população geral no Brasil é de 0,5% ao ano. Estes resultados indicam que os estudantes de enfermagem são um grupo de risco para infecção por tuberculose. Dentre os fatores de risco estudados somente o uso da máscara NIOSH95 estava associado à proteção contra a infecção (RR=0,2. Não houve diferença estatisticamente significativa entre os estudantes que converteram o PPD e aqueles que permaneceram negativos em relação ao conhecimento sobre tuberculose e existência de condições específicas para hospitalização dos pacientes com tuberculose. Nossos dados reforçam a necessidade de implementação programas de biosegurança especiais visando este grupo de profissionais.

    Full Text Available This study examined the spatial and temporal variations of 13 physico-chemical parameters in water and sediment samples collected along the rural and urban section of Verruga Stream. The metal concentrations were determined by FAAS. The conductivity and the concentration of Na+, Cl-, and Ca2+ showed the largest variations in the urban area demonstrating that these parameters are appropriate indicators of urban contamination. The application of cluster and principal component analysis showed that the Cd2+ and Mn2+ are associated with the use of fertilizers in the rural area.

    2014-01-01

    Full Text Available Introduction. Macrophage reprogramming is vital for resolution of acute inflammation. Parenteral vitamin C (VitC attenuates proinflammatory states in murine and human sepsis. However information about the mechanism by which VitC regulates resolution of inflammation is limited. Methods. To examine whether physiological levels of VitC modulate resolution of inflammation, we used transgenic mice lacking L-gulono-γ-lactone oxidase. VitC sufficient/deficient mice were subjected to a thioglycollate-elicited peritonitis model of sterile inflammation. Some VitC deficient mice received daily parenteral VitC (200 mg/kg for 3 or 5 days following thioglycollate infusion. Peritoneal macrophages harvested on day 3 or day 5 were examined for intracellular VitC levels, pro- and anti-inflammatory protein and lipid mediators, mitochondrial function, and response to lipopolysaccharide (LPS. The THP-1 cell line was used to determine the modulatory activities of VitC in activated human macrophages. Results. VitC deficiency significantly delayed resolution of inflammation and generated an exaggerated proinflammatory response to in vitro LPS stimulation. VitC sufficiency and in vivo VitC supplementation restored macrophage phenotype and function in VitC deficient mice. VitC loading of THP-1 macrophages attenuated LPS-induced proinflammatory responses. Conclusion. VitC sufficiency favorably modulates macrophage function. In vivo or in vitro VitC supplementation restores macrophage phenotype and function leading to timely resolution of inflammation.

    Maternal micronutrient deficiencies may adversely affect fetal and infant health, yet there is insufficient evidence of effects on these outcomes to guide antenatal micronutrient supplementation in South Asia. To assess effects of antenatal multiple micronutrient vs iron-folic acid supplementation on 6-month infant mortality and adverse birth outcomes. Cluster randomized, double-masked trial in Bangladesh, with pregnancy surveillance starting December 4, 2007, and recruitment on January 11, 2008. Six-month infant follow-up ended August 30, 2012. Surveillance included 127,282 women; 44,567 became pregnant and were included in the analysis and delivered 28,516 live-born infants. Median gestation at enrollment was 9 weeks (interquartile range, 7-12). Women were provided supplements containing 15 micronutrients or iron-folic acid alone, taken daily from early pregnancy to 12 weeks postpartum. The primary outcome was all-cause infant mortality through 6 months (180 days). Prespecified secondary outcomes in this analysis included stillbirth, preterm birth (birth weight (births) in the iron-folic acid group and 741 deaths (51.6 per 1000 live births) in the multiple micronutrient group (relative risk [RR], 0.95; 95% CI, 0.86-1.06). Multiple micronutrient supplementation resulted in a non-statistically significant reduction in stillbirths (43.1 vs 48.2 per 1000 births; RR, 0.89; 95% CI, 0.81-0.99; P = .02) and significant reductions in preterm births (18.6 vs 21.8 per 100 live births; RR, 0.85; 95% CI, 0.80-0.91; P birth weight (40.2 vs 45.7 per 100 live births; RR, 0.88; 95% CI, 0.85-0.91; P supplementation did not reduce all-cause infant mortality to age 6 months but resulted in a non-statistically significant reduction in stillbirths and significant reductions in preterm births and low birth weight. clinicaltrials.gov Identifier: NCT00860470.

    The high prevalence of iron deficiency in the population is widely acknowledged, but there are not yet sufficient studies that explain the reasons for this problem at local and national level. Thus, the scope of this study was to evaluate the prevalence of anemia and its relation with socio-demographic and anthropometric aspects of children living in Vitoria, Espírito Santo. This is a cross-sectional study conducted among 12- to 72-month-old children. Data were collected in Primary Healthcare Units and involved the hemoglobin dosage, height and weight measurement, in addition to the application of a semi-structured questionnaire to gather socio-demographic information. The evaluation included 980 children, 51.1% of which were female with a median age of 46.00 (95%CI: 45.52 - 48.09) months. Anemia was found in 37%, with a hemoglobin median of 11.4 (95%CI: 11.15 - 11.36) g/dL. The children's' height/age ratio (p = 0.049) and the number of people in the family (p < 0.001) were found to be determinants of anemia, and age was a factor of protection for this deficiency (p = 0.010). The high prevalence of anemia and its strong relation with demographic and anthropometric data suggest the need for more effective public policies than just food fortification and supplementation.

  2. Role of vitamin D in children with respiratory tract infection.

    Esposito, S; Baggi, E; Bianchini, S; Marchisio, P; Principi, N

    2013-01-01

    It has recently been shown that vitamin D (VitD) plays an important role in host defences, inflammation and immunity. We reviewed PubMed and selected all of the studies published over the last 15 years concerning VitD deficiency and VitD supplementation in children with respiratory tract infections. Our analysis showed that VitD seems to be very important because of its part in the complexity of the immune system. However, there are few pediatric studies and most have various limitations. First of all, the literature mainly refers to studies concerning the prevalence of VitD insufficiency and deficiency in specific pathologies. Secondly, it is extremely difficult to identify a common specific range of normal, insufficient and deficient VitD levels. Thirdly, the available studies of VitD supplementation often combined VitD with the use of other micronutrients, thus obscuring the role of VitD itself. Finally, different doses have been used for VitD supplementation. These observations clearly highlight the fact that further studies are needed to evaluate the impact of VitD deficiency and insufficiency in terms of the epidemiology and outcomes of pediatric respiratory tract infection, and whether VitD supplementation favours a positive outcome.

    Vitamin D (VitD) is a prohormone most noted for the regulation of calcium and phosphate levels in circulation, and thus of bone metabolism. Inflammatory and immune cells not only convert inactive VitD metabolites into calcitriol, the active form of VitD, but also express the nuclear receptor of VitD that modulates differentiation, activation and proliferation of these cells. In vitro, calcitriol upregulates different anti-inflammatory pathways and downregulates molecules that activate immune and inflammatory cells. Administration of VitD has beneficial effects in a number of experimental models of autoimmune disease. Epidemiologic studies have indicated that VitD insufficiency is frequently associated with immune disorders and infectious diseases, exacerbated by increasing evidence of suboptimal VitD status in populations worldwide. To date, however, most interventional studies in human inflammatory and immune diseases with VitD supplementation have proven to be inconclusive. One of the reasons could be that the main VitD metabolite measured in these studies was the 25-hydroxyVitD (25OHD) rather than its active form calcitriol. Although our knowledge of calcitriol as modulator of immune and inflammatory reactions has dramatically increased in the past decades, further in vivo and clinical studies are needed to confirm the potential benefits of VitD in the control of immune and inflammatory conditions.

    Laparoscopic sleeve gastrectomy (LSG) reduces obesity-related co-morbidities, such as diabetes, hypertension, and hyperlipidemia. Endocrinological abnormalities may occur as undesired side effects. Most centers routinely prescribe folic acid, cyanocobalamin (vitB12), and protein replacement in the postoperative period, but 25-OH-vitamin-D3 (vitD) and intact parathyroid hormone (iPTH) levels are not routinely followed up. The aim of this study was to identify the effects of LSG on iPTH, vitD, calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), and albumin levels. Data of morbidly obese patients who underwent LSG between January and December 2014 were studied in this prospectively designed study. Serum levels of iPTH, vitD, Ca, P, folic acid, vitB12, ALP, and albumin were measured preoperatively and postoperatively at the 3rd, 6th, and 12th months. In total, 119 patients were analyzed. All patients had normal iPTH, vitD, Ca, P, folic acid, vitB12, ALP, and albumin values preoperatively, and 31.6% had received vitD supplementation during their nutritionist observation time before surgery. At the 3rd, 6th, and 12th postoperative months, 21 (17.6%), 17 (17.3%), and 1 (0.8%) patients, respectively, had increased iPTH and ALP and decreased vitD levels. A total of 39 (32.7%) patients needed high-dose vitD treatment during a 1 year follow-up. Approximately 37.5% of the patients who received vitD supplementation preoperatively needed vitD supplementation postoperatively. Hospital records of 101 of 119 patients who underwent LSG could be screened to determine their vitD supplementation requirements previously ordered by their nutritionist for a 1-year period before LSG. Thirty-two (31.6%) of the 101 patients had received vitD supplementation during the 1-year period preoperatively. Although serum levels of iPTH, vitD, Ca, P, vitB12, ALP, and albumin may be normal preoperatively, severe vitD insufficiency requiring high-dose vitD replacement may develop in morbidly

    Full Text Available Stored red blood cells (RBCs undergo oxidative stress that induces deleterious metabolic, structural, biochemical, and molecular changes collectively referred to as “storage lesions”. We hypothesized that vitamin C (VitC, reduced or oxidized would reduce red cell storage lesions, thus prolonging their storage duration. Whole-blood-derived, leuko-reduced, SAGM (saline-adenine-glucose-mannitol-preserved RBC concentrates were equally divided into four pediatric storage bags and the following additions made: (1 saline (saline; (2 0.3 mmol/L reduced VitC (Lo VitC; (3 3 mmol/L reduced VitC (Hi VitC; or (4 0.3 mmol/L oxidized VitC (dehydroascorbic acid, DHA as final concentrations. Biochemical and rheological parameters were serially assessed at baseline (prior to supplementation and Days 7, 21, 42, and 56 for RBC VitC concentration, pH, osmotic fragility by mechanical fragility index, and percent hemolysis, LDH release, glutathione depletion, RBC membrane integrity by scanning electron microscopy, and Western blot for β-spectrin. VitC exposure (reduced and oxidized significantly increased RBC antioxidant status with varying dynamics and produced trends in reduction in osmotic fragility and increases in membrane integrity. Conclusion: VitC partially protects RBC from oxidative changes during storage. Combining VitC with other antioxidants has the potential to improve long-term storage of RBC.

    In this study, pulsed electric fields (PEF) treatments and their effects on the structure of vitamin C (VIT-C) were estimated by fluorescence and Fourier transform infrared (FT-IR) spectroscopy, the relative content of VIT-C was measured by HPLC and the antioxidant properties of treated VIT-C by DPPH radical scavenging as well as reducing power tests. The fluorescence intensity of treated VIT-C increased slightly compared to the untreated VIT-C. Moreover, the effect of PEF on the structure of VIT-C was observed using the FT-IR spectra. These phenomena indicated that the PEF affected the conformation of VIT-C, which promoted the VIT-C isomer transformed enol-form into keto-form. In addition, the PEF treatments did not suffer the damage to VIT-C and could slow down the oxidation process in involving of experimental conditions by HPLC. The antioxidant properties of the treated VIT-C were enhanced, which was proved by radical scavenging and also the reducing power tests. PMID:26473846

    Dietary intake of vitamin D includes vitamin D3 (vitD3), 25-hydroxyvitamin D3 (25OH-D3), and vitamin D2 (vitD2). However, the bioactivity of the different species has not been scientifically established. The hypothesis in this study was that vitD3, 25OH-D3, and vitD2 have an equal effect on 25......-hydroxyvitamin D in serum (vitamin D status). To test our hypothesis, we performed a randomized, crossover study. Twelve young males consumed 10 µg/day vitD3 during a four-week run-in period, followed by 3 × 6 weeks of 10 µg/day vitD3, 10 µg/day 25OH-D3, and 10 µg/day vitD2. The content of vitD3, vitD2, 25OH-D3......, and 25-hydroxyvitamin D2 (25OH-D2) in serum was quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The hypothesis that the three sources of vitamin D affect vitamin D status equally was rejected. Based on the assumption that 1 µg vitD3/day will show an increase in vitamin D status...

    The extremely low-frequency electromagnetic field (ELF-EMF), mainly emitted by electric transmission lines and household electronic appliances, is becoming a worldwide health risk. It is imperative to investigate the biological impacts of ELF-EMF and to identify products that are resistant to the radiation from 50 Hz ELF-EMF. In this study, we investigated the biological impacts of apoptosis caused by 50 Hz Power line ELF-EMF and the protective effects of Vit C and Vit E. We conducted this study in Beijing, China in 2013. B95-8 and Balb/c-3T3 cells were divided into a sham group, an expo group and 3 expo groups in which the cells were preincubated with various concentrations of Vit C and Vit E. Then, all of the cells were exposed to 50 Hz Power line ELF-EMF and examined for apoptosis. The cells were collected for apoptosis detection after exposure. The percent of cells that undergoing apoptosis and preincubated with various concentrations of Vit C and Vit E were significantly lower than in the Expo group. Vit C and Vit E exert significant protective effects from 50 Hz ELF-EMF radiation. The optimal protective concentrations of Vit C and Vit E are 10 μmol/L and 25 μmol/L, respectively. The protective effect of vitamins was more apparent for Balb/c-3T3 cells than B95-8 cells.

    Venom immunotherapy (VIT) with aqueous extracts is considered a life-saving treatment in insect allergy, but systemic side effects are quite common, especially in patients sensitized to Apis mellifera venom. Only a few studies are available regarding depot VIT administered according to the standard weekly schedule, while no data are available for cluster VIT with depot preparations. This study was designed to compare the tolerance of aqueous cluster or rush VIT versus cluster depot VIT in patients sensitized to Apis mellifera. Fifty-five patients with a history of systemic reaction (grade II to IV according to Müller) after an Apis mellifera sting were divided at random into 3 groups. Forty patients were treated with aqueous VIT (20 according to a cluster schedule and 20 according to a rush schedule) and 15 with Depot VIT according to a cluster schedule. All local and systemic side effects were recorded. Four patients belonging to the aqueous-cluster, 4 belonging to the aqueous-rush, and 1 belonging to the depot-cluster schedule had large local reactions after VIT (p < 0.009). Systemic side effects were recorded in 1, 7 and 0 patients (p < 0.003) respectively. No statistically significant difference was found between the two cluster regimens in the frequency of side effects. Depot VIT administered according to a cluster schedule was well tolerated, and its tolerance is better than aqueous-rush VIT for Apis mellifera.

    To examine the effect of high doses of vitamin C (VitC) on ex vivo human platelets (PLTs). Platelet concentrates collected for therapeutic or prophylactic transfusions were exposed to: (1) normal saline (control); (2) 0.3 mmol/L VitC (Lo VitC); or (3) 3 mmol/L VitC (Hi VitC, final concentrations) and stored appropriately. The VitC additive was preservative-free buffered ascorbic acid in water, pH 5.5 to 7.0, adjusted with sodium bicarbonate and sodium hydroxide. The doses of VitC used here correspond to plasma VitC levels reported in recently completed clinical trials. Prior to supplementation, a baseline sample was collected for analysis. PLTs were sampled again on days 2, 5 and 8 and assayed for changes in PLT function by: Thromboelastography (TEG), for changes in viscoelastic properties; aggregometry, for PLT aggregation and adenosine triphosphate (ATP) secretion in response to collagen or adenosine diphosphate (ADP); and flow cytometry, for changes in expression of CD-31, CD41a, CD62p and CD63. In addition, PLT intracellular VitC content was measured using a fluorimetric assay for ascorbic acid and PLT poor plasma was used for plasma coagulation tests [prothrombin time (PT), partial thrombplastin time (PTT), functional fibrinogen] and Lipidomics analysis (UPLC ESI-MS/MS). VitC supplementation significantly increased PLTs intracellular ascorbic acid levels from 1.2 mmol/L at baseline to 3.2 mmol/L (Lo VitC) and 15.7 mmol/L (Hi VitC, P 0.05). PLT function assayed by TEG, aggregometry and flow cytometry was not significantly altered by Lo or Hi VitC for up to 5 d. However, PLTs exposed to 3 mmol/L VitC for 8 d demonstrated significantly increased R and K times by TEG and a decrease in the α-angle (P 0.05). Collagen and ADP-induced ATP secretion was also not different between the three groups (P > 0.05). Finally, VitC at the higher dose (3 mmol/L) also induced the release of several eicosanoids including thromboxane B2 and prostaglandin E2, as well as products of

    While having the highest vitamin C (VitC) concentrations in the body, specific functions of VitC in the brain have only recently been acknowledged. We have shown that postnatal VitC deficiency in guinea pigs causes impairment of hippocampal memory function and leads to 30% less neurons. This study...... investigates how prenatal VitC deficiency affects postnatal hippocampal development and if any such effect can be reversed by postnatal VitC repletion. Eighty pregnant Dunkin Hartley guinea pig dams were randomized into weight stratified groups receiving High (900 mg) or Low (100 mg) VitC per kg diet. Newborn...... pups (n = 157) were randomized into a total of four postnatal feeding regimens: High/High (Control); High/Low (Depleted), Low/Low (Deficient); and Low/High (Repleted). Proliferation and migration of newborn cells in the dentate gyrus was assessed by BrdU labeling and hippocampal volumes were determined...

    Full Text Available Vit. D is a steroid prohormone. It is synthesized in the skin under ultra –violet light exposure. Traditionally, Vit.D3, cholecalciferol and calcitriol were known to have a role only in calcium and bone mineral metabolism. This article takes an account of the current view on the impact of Vit D deficiency on human health. Research has now shown the indisputable role of Vit D in prevention/treatment of some cancers, osteoporosis, rheumatoid arthritis, multiple sclerosis, tuberculosis, hypertension, and diabetes mellitus. In addition lower maternal Vit. D levels are associated with Pregnancy Induced Hypertension (PIH, suggesting that Vit. D deficiency may be a modifiable risk factor for PIH. Greater awareness of the problem of a high prevalence of vitamin D inadequacy is required among researchers, clinicians, and patients. Special efforts on the medical and social fronts are nec­essary to combat this preventable epidemic of vitamin D deficiency.

    Full Text Available As estratégias de desenvolvimento rural, associadas ao debate sobre agricultura familiar, têm destacado formas alternativas de produção agrícola para os territórios agrários do Rio Grande do Sul. Na Região Serrana, é significativa a produção de uva com base ecológica, bem como convencional. Embora os sistemas coexistam, eles apresentam características peculiares ao modus operandi. Destarte, a pesquisa visa identificar qual dos sistemas de produção apresenta o melhor resultado econômico, uma vez que ele pode influenciar na tomada de decisão entre adotar um ou outro sistema. Para tanto, ela possui abordagem quantitativa com objetivos exploratórios e procedimentos de levantamento de informações, por intermédio de entrevista semiestruturada. Operacionalmente, a classificação dos custos evidenciou um comportamento semelhante na distribuição das despesas entre os sistemas produtivos, sendo que as maiores despesas concentram-se nos custos fixos. No sistema convencional, a renda bruta, total e operacional, é mais elevada. Devido às particularidades da produção agropecuária, o processo de tomada de decisão sobre quanto, o que e como produzir é condicionado pela disponibilidade de recursos, pelos objetivos econômico-financeiros e pelas implicações deste no bem-estar da família. Portanto, identificar a condição mais próxima da ideal que condicione o agricultor a adotar um sistema produtivo baseado nos princípios da agroecologia ou por meio de práticas convencionais pode ser um dos desafios.

    Recent evidence about the various effects of vitamin D (vit D) on innate and adaptive immunity has led to a search for the role of vit D in asthma. It is postulated that a decrease in cathelicidin, a multifunctional host defense molecule, production due to low vit D status may predispose to infectious complications in children with asthma. The aim of this study was to determine the association of vit D, vit D-binding protein (VDBP) and cathelicidin with acute asthma attacks among children with allergic asthma. This prospective study included 35 patients with acute asthma attack and 32 children with controlled asthma, and all were matched by sampling season, sensitization to mites, and previous severity of asthma. A comprehensive questionnaire about risk factors, blood sampling for 25-hydroxyvitamin D vit D, VDBP, and cathelicidin levels; spirometric indices were used. Factors that influence serum vit D and cathelicidin levels and the development of asthma attacks were evaluated with multivariate analysis. The mean serum vit D levels of the attack group was significantly lower than that of the controlled asthma group (p asthma group than with the controlled subjects with asthma (p = 0.002). There was no difference between the acute and controlled asthma groups in terms of markers of allergy and serum VDBP levels. Risk factors that may influence vit D levels revealed that body mass index (BMI) (p = 0.038), duration of sun exposure (p , and amount of dietary vit D (p asthma showed that low serum levels of vit D were significantly related to the risk of asthma attacks (p , adjusted odds ratio 16.11). Cathelicidin levels showed a significant positive association with asthma attacks and BMI. Vit D deficiency showed a significant relationship to the development of asthma attacks independent of cathelicidin deficiency and other factors associated with the severity of chronic asthma.

    Here, we studied the beneficial effects of aerobic exercise on metabolic syndrome components, cognitive performance, brain derived neurotrophic factor (BDNF) and irisin in ovariectomized rats with different serum vitamin D (Vit D) status. Eighty female wistar rats were divided into 2 groups of sham operated (sham, n = 8), and ovariectomized (OVX, n = 72). Then OVX were divided into 9 groups of receiving combination of exercise protocol with low dose of Vit D (OVX + EXE + LD), high dose of Vit D (OVX + EXE + HD), Vit D deficiency (OVX + EXE - D), and (OVX + EXE + Veh). Also non exercised groups of OVX receiving high dose of Vit D (OVX + HD), low dose of Vit D (OVX + LD), Vit D deficiency (OVX - D), and Veh (OVX + Veh) were included. After 2 months of related interventions, spatial memory was assessed using Morris water maze (MWM), and then metabolic syndrome components were measured. High dose of Vit D supplementation showed significant reduction in weight (p = 0.001), lipid profiles (p = 0.001), visceral fat (p = 0.001) and waist circumference (p = 0.001) regardless of exercising or not, with no change in cognitiive function. Serum BDNF level was significantly higher in Vit D deficient group (p = 0.001), and was decreased in the OVX + HD. In contrary, irisin did not show any significant relationship with serum concentration of Vit D, while it was significantly elevated in the exercised groups compared with non-exercised counterparts. Vit D insufficiency deteriorates metabolic syndrome components, and elevates serum BDNF as a compensatory metabotropic factor, and further supplementation significantly attenuates these components parallel with reduction in BDNF. In addition, aerobic exercise successfully induces various metabolic benefits, provided optimum serum level of Vit D.

    Full Text Available Background: Thalassemic patients undergoing Hematopoietic Stem Cell Transplantation (HSCT are faced with cumulative high level of oxidative stress and depletion of critical antioxidants. Administration of antioxidants, is promising towards minimizing oxidative damage in both thalassemic and HSCT patients.Method: This was a prospective cross-sectional observational study. Patients as a part of institutional protocol were received Vitamin C (Vit C (all the patients received oral Vit C; 200 mg and 400 mg Vit C, if they were less or more than 20 kg respectively plus 10 mg/kg/day intravenous infusion of Vit C.We measured plasma Vit C and total antioxidant (TAs levels at four different time points; baseline, transplantation day (0, day +7 and day +14. We calculated mean and standard error for plasma levels of Vit C and TAs.Results: Fifthy patients enrolled in this study (mean age 7.97± 3.53. In all four time points, means of Vit C and TAs serum levels were under their reference values and their highest means were belong to baseline. Serum TAs and Vit C both depleted significantly from baseline to day 0 (P: 0.00 for both variables, then increased up to day +7 and it keeps rising till day +14 (P: 0.00 from day0 to day +7 and +14 for both variables. These changes were significant through the measurement time. There is also a significant correlation between baseline Vit C and baseline TAs (P: 0.11. This means the higher level of Vit C is correlated with higher level of TAs and vice versa.Conclusion: We did not observe any beneficial effects of administering Vit C in thalassemic patients undergoing HSCT in order to increase or prevent depletion of Vit C and TAs serum levels. This could be resolved by further investigations carrying out higher doses or longer duration and having a control group.

    Vitamin D (Vit D) deficiency is a common disorder in diabetic patients and may be a risk factor for ischemic heart disease and exacerbation of diabetic nephropathy(DN). The aim of this study was to evaluate the effect of Vit D3 therapy on protein uriain type 2 diabetic patients with deficient or insufficient serum Vit D. In a double blind clinical trial, 60 type 2 diabetic patients with proteinuria greater than 150 mg/day who had Vit D deficiency or insufficiency were randomly enrolled in two equal groups. Pearl of Vit D as 50 000 IU/week and placebo (1 tablet per week) were prescribed in patients of case and control groups respectively for 8 weeks. At the beginning and 2 months later, 24 hours urine protein was checked in all patients. There is no difference between serums Vit D level in case and control group at the beginning of the study, however at the end of the study serum Vit D level was significantly higher in the case group. There is no difference in proteinuria between case and control group at the beginning and the end of the study, while a significant difference between the changes of proteinuria before and after the study was seen in two groups ( P = 0.028). Vit D deficiency may exacerbate protein uric and DN, hence correction of Vit D deficiency may decrease proteinuria in diabetic patients with nephropathy.

    The role of vitamin D (VitD) in calcium and bone homeostasis is well described. In the last years, it has been recognized that in addition to this classical function, VitD modulates a variety of processes and regulatory systems including host defense, inflammation, immunity, and repair. VitD deficiency appears to be frequent in industrialized countries. Especially patients with lung diseases have often low VitD serum levels. Epidemiological data indicate that low levels of serum VitD is associated with impaired pulmonary function, increased incidence of inflammatory, infectious or neoplastic diseases. Several lung diseases, all inflammatory in nature, may be related to activities of VitD including asthma, COPD and cancer. The exact mechanisms underlying these data are unknown, however, VitD appears to impact on the function of inflammatory and structural cells, including dendritic cells, lymphocytes, monocytes, and epithelial cells. This review summarizes the knowledge on the classical and newly discovered functions of VitD, the molecular and cellular mechanism of action and the available data on the relationship between lung disease and VitD status.

    Full Text Available Abstract Background: Phenylhydrazine (PHZ as a strong oxidant agent causes variety of toxic effects including alterations in the biochemical and cardiac tissue. The aim of the present study was to investigate the effects of royal jelly (RJ and vitamin C (vit C against PHZ-induced cardiotoxicity in mice. Materials and Methods: Adult male mice were randomly assigned to eight groups of eight mice each. PHZ was administered to four groups of mice at a dose of 60 mg/kg per 48 hours intraperitoneally for 35 days. Three of these groups received vit C (250 mg/kg per day intraperitoneally, RJ (100 mg/kg per day orally and vit C+RJ with same doses four hours before PHZ administration, respectively. A vehicle-treated control group and vit C, RJ and vit C+RJ control groups were also included. Results: RJ and vit C significantly decreased (p< 0.05 the serum level of malondialdehyde and creatine kinase (CK-BM that had been increased by PHZ. Also, RJ and vit C increased the total antioxidant capacity and supraxoid dismutase serum that had been decreased by induced PHZ. Moreover, RJ and vit C could improve the tissue damages induced by PHZ such as diffused edema, hemorrhage, congestion, hyaline exudates, necrosis and also fibrosis tissue in heart tissue. Conclusion: It seems that Vit C and RJ can minimize PHZ-induced cardiotoxicity in mouse through oxidative reactions inhibition.

    Rush venom immunotherapy (VIT) is highly effective in vespid venom allergy, but comparable data regarding bee venom (BV) allergy are sparse. We evaluated its safety, efficacy and cost in BV-allergic patients. Conventional or rush VIT were offered to all patients with systemic reaction to insect sting. Rush VIT was also given to hyperreactive patients who failed to reach the maintenance dose with conventional VIT due to multiple systemic reactions. In BV-allergic patients, honeybee sting challenge was performed within 1 week after reaching the maintenance dose. 179 patients, some of them allergic to more than one venom, received 246 rush VIT courses. Bee VIT was administered to 132 patients (73.7%); 173 patients (96.6%) reached the maintenance dose. The incidence of systemic reactions was 29.6%. They were more common in VIT with BV than with vespid venoms (31.1 and 16.3%, respectively, p = 0.01). After excluding the hyperreactive subgroup (n = 20), this difference was not significant (23.7 and 16%, respectively, p = 0.19). Despite the high incidence of systemic reactions (15 of 20, 75%) among hyperreactive patients, 17 patients (85%) achieved the maintenance dose. Sting challenges resulted in systemic reaction in 4 of 8 (50%) hyperreactive patients and in 2 of 47 (4.3%) ordinary patients. The cost of rush VIT was 41% of that of conventional VIT. Rush VIT with BV is safe, instantaneously effective, less expensive and enables most patients with previous failures of conventional VIT to reach the maintenance dose. Copyright © 2011 S.

    Full Text Available A total of 216 laying hens was kept at high ambient temperature (32±4°C, 60% relative humidity from week 24 to 32 of age. Birds were divided in 8 treatments with 9 replicates of 3 hens each. The groups were fed the same basal diet and submitted to these dietary treatments: control, un-supplemented; green tea (GT, fed GT at 1 g/kg diet; brown marine algae (BMA, fed BMA at 1 g/kg diet; vitamin E (vit. E, fed vit. E at 300 mg/kg diet; GT+BMA, fed GT and BMA at 1 g/kg of each; GT+vit. E, fed GT and vit. E at 1 g and 300 mg/kg, respectively; BMA+vit. E, fed BMA and vit. E at 1 g and 300 mg/kg, respectively. Feeding BMA at 0.1% increased laying rate by 1.2% and improved feed conversion ratio by 5.2% compared to the control. Vitamin E significantly increased shell thickness by 6.6% and Haugh unit by 4.6% compared to the control. In addition, BMA+vit. E or GT+vit. E increased yolk colour by 9.1 and 10.7%, and Haugh unit of stored eggs by 10.9 and 11.1%. Cholesterol of fresh eggs and plasma were significantly decreased by 16.0 and 9.4% due to supplementation with BMA, and by 19.2 and 8.1% with vit. E addition. Plasma phosphorus increased by 19.1% after vit. E+BMA supplementation. In conclusion, use of BMA or vit. E or GT in laying hens diets which grow under heat stress is recommended as it improves production performance and egg quality.

    Full Text Available The aims of this study were to evaluate the effect of vitamin E (vit E and black tea extract (BTE as antioxidant sources in high poly-unsaturated fatty acid (PUFA rations on blood malondialdehyde (MDA concentrations and the performance of reproduction and lactation of Garut ewes. Twelve ewes on late pregnancy periods were divided into completely randomized design (CRD with 3 treatments and 4 replicates. The treatments were control: basal diet without antioxidant, vit E: basal diet supplemented with vit E, and BTE: basal diet supplemented with BTE. The results showed that vit E and BTE supplementation did not affect blood MDA concentration of ewes on late pregnancy, lactation periods, and weaning periods. Antioxidant sources supplementation had no effect on ewe’s nutrient intake, pre-lambing live weight change (LWC, and post-lambing average daily gain (ADG. Vit E supplementation had decreased the milk production, but both of antioxidant sources give positive effect on the milk composition. Nevertheless, the supplementation of vit E and BTE increased the twin type of birth. The vit E supplementation resulted higher lambing rate than BTE, although it had the highest mortality rate of twin lamb. BTE also had better lamb weaning weight than vit E. BTE and vit E gave similar results in ewes productivity on lactation period. In conclusion, this study confirmed that BTE was more effective used as antioxidant source than vit E to prevent the oxidative reaction of PUFA. Vit E supplementation on high PUFA ration reduced ewes milk production but it had similar reproduction performance with BTE.

    Rush venom immunotherapy (VIT) is highly effective in Hymenoptera venom allergy. Still, specific data regarding its safety and efficiency in children are rather sparse. The objective of this study was to better evaluate the safety and efficiency of rush VIT in this specific age group. Children younger than 16 years with systemic reaction to insect sting involving, at least, one body system other than skin and children aged 16-18 years with any kind of systemic reaction were offered conventional or rush VIT with a build-up phase that lasted 3 days. Eighty-four of 127 children together with their caregivers chose to receive rush VIT. Seventy of them were allergic to bee venom only. There was no difference between the children receiving rush or conventional VIT in the incidence of systemic reactions during the build-up phase (19% and 23.2%, respectively), nor was there any difference in regard to the severity of these reactions. Efficiency was improved with rush VIT, as reflected by a higher number of patients achieving the 100 mcg maintenance dose with the primary protocol (83 of 84 patients, 98.8%, and 39 of 43, 90.7%, for rush and conventional, respectively, P = .04). Rush VIT in children is as safe as and more efficient than conventional VIT. Copyright © 2016 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc. All rights reserved.

    Full Text Available New Zealand has one of the highest rates of Crohn’s Disease (CD in the world, and there is much speculation as to why this might be. A high risk of CD has been associated with deficient or insufficient levels of Vitamin D (Vit D, lifestyle as well as various genetic polymorphisms. In this study we sought to analyse the relevance of serum Vit D levels, lifestyle and genotype to CD status. Serum samples were analysed for 25-OH-Vitamin D levels. DNA was isolated from blood and cheek-swabs, and Sequenom and ImmunoChip techniques were used for genotyping. Serum Vit D levels were significantly lower in CD patients (mean = 49.5 mg/L than those found in controls (mean = 58.9 mg/L, p = 4.74 × 10−6. A total of seven single nucleotide polymorphisms were examined for effects on serum Vit D levels, with adjustment for confounding variables. Two variants: rs731236[A] (VDR and rs732594[A] (SCUBE3 showed a significant association with serum Vit D levels in CD patients. Four variants: rs7975232[A] (VDR, rs732594[A] (SCUBE3, and rs2980[T] and rs2981[A] (PHF-11 showed a significant association with serum Vit D levels in the control group. This study demonstrates a significant interaction between Vit D levels and CD susceptibility, as well as a significant association between Vit D levels and genotype.

    Experiments in vitro, using bacteria Escherichia coli (AB 1157) as a biological model, showed that the cytostatic efficiency of sanazole (AK-2123, a nitrotriazole-type radiosensitizer) in radiation treatment can be strongly influenced by the presence of various vitamins. In airfree media the sanazole action is increased by a factor of 2.5 in the presence of vitamin (vit.) B1, vit. C E-acetate and β-carotene, whereas vit. B1 used individually possesses a 2.7-times higher cytostatic activity than sanazole itself. In media containing air the highest increase of sanazole action is observed in the presence of vit. B1 and C, whereas the individual use of vit. B1 shows a radiation protection effect. In media saturated with N 2O the addition of the vit. B1 and C causes a 1.8-times larger sanazole activity, but the application of vit. B1 alone brings about a very high radiation protection. From studies of vit. B1-radiolysis it can be concluded that OH radicals are the major primary transients leading to substrate degradation. The results are of interest for the radiation therapy of cancer.

  9. Sun protection and Vitamin D: three dimensions of obfuscation.

    Gilchrest, Barbara A

    2007-03-01

    Ultraviolet (UV) radiation is a proven carcinogen, responsible for more than half of all human malignancies. It also compromises skin appearance and function. Since the UV action spectra for DNA damage, skin cancer and Vitamin D(3) (vit D) photosynthesis are identical and vit D is readily available from oral supplements, why has sun protection become controversial, now that some data suggest conventionally "sufficient" levels of vit D may be less than optimal for at least some population groups? First, the media and apparently some researchers are hungry for a new message. Nevertheless, after 50 years, UV exposure is still a major avoidable health hazard. Second, the controversy is fueled by a powerful special interest group: the indoor tanning industry. They target not the frail elderly or inner-city ethnic minorities, groups for whom evidence of vit D insufficiency is strongest, but rather fair-skinned teenagers and young adults, those at highest risk of UV photodamage. Third, evolution does not keep pace with civilization. When nature gave man the appealing capacity for vit D photosynthesis, the expected lifespan was far less than 40 years. Long-term photodamage was not a concern, and vit D was not available at the corner store. The medical community should avoid sensationalism and instead rigorously explore possible cause-and-effect relationships between vit D status and specific diseases while advocating the safest possible means of assuring vit D sufficiency.

    In many European centers insect venom allergic patients with a reaction confined to the skin are only offered an epinephrine auto-injector and not venom immunotherapy (VIT). Previously we showed that VIT improves health-related quality of life (HRQL) of yellow jacket allergic patients with more than dermal reactions. To examine whether HRQL of dermal reactors is impaired and to examine the influence of VIT on HRQL in comparison with the EpiPen. Patients with solely dermal reactions were asked if they were willing to be randomized either to VIT or EpiPen, after receiving patient information. Before and 1 year after enrollment, patients completed the Vespid allergy Quality of Life Questionnaire (VQLQ), Burden of Treatment and Expectation of Outcome. Of 55 patients eligible for the study, 29 consented to randomization: 15 to VIT, 14 to EpiPen. The remaining 26 patients preferred to choose their treatment: 11 VIT and 15 EpiPen. The VQLQ score of patients randomized to VIT improved (mean change 0.83 (SD 0.87), in contrast to patients randomized to the EpiPen whose scores deteriorated (mean change -0.42 (SD 0.64), P EpiPen. VIT results in a clinically significant improvement of HRQL in most patients with reactions limited to the skin following yellow jacket stings. Prescription of an EpiPen in patients not choosing this treatment is associated with deterioration in HRQL and should therefore be avoided as definitive treatment in these patients.

    The effects of different polymer types on inhibiting the crystallization of ascorbic acid (VitC) from amorphous solid dispersions at various temperatures and relative humidities (RHs) were studied. Polymer properties (ability to form hydrogen bonds with VitC, hygroscopicity, and glass transition temperature (Tg)) were correlated to their crystallization inhibitor performance. Solid dispersions of VitC with different pectins, polyvinylpyrrolidone (PVP), and polyacrylic acid (PAA) were formed from lyophilized solutions. Crystallinity, VitC-polymer interactions, hygroscopicity, and Tg were determined using X-ray powder diffraction (XRPD), Fourier transform infrared spectroscopy (FTIR), moisture sorption isotherm, and differential scanning calorimetry (DSC) methods, respectively. XRPD amorphous VitC could not be formed by lyophilization in the absence of a polymer, nor in PAA dispersions, but could be formed in pectin and PVP dispersions. The VitC-pectin and PVP dispersions remained amorphous when stored at low RHs, but some crystallization occurred within one week at high RHs. Evidence of hydrogen bonding between VitC and both pectins and PVP, but not PAA, was found in FTIR spectra, and correlated better with physical stability than the Tg. The hygroscopicity of the polymer also influenced the stability of the amorphous VitC solid dispersions. A ranking of the polymer crystallization inhibitor properties was: PVP>pectin with lower degree of esterification (DE)>pectin with higher DE >PAA. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Patients with diabetes (DM) and chronic kidney disease (CKD) are at increased risk for suboptimal bone health. The study objective was to investigate the relationships between vitamin D (vitD), vitamin K1 (vitK1), and calcium intake with bone mineral density (BMD) and vitamin D status in an ambulatory population with DM and CKD. Adults (age 18-80 years; n = 62) with DM and CKD (stages 1-4) were recruited from the Northern Alberta Renal Program. Primary outcome variables included vitD, vitK1, and calcium intake; serum 25(OH)D, 1,25(OH)2D; and BMD as measured by dual X-ray absorptiometry. Statistical significance was determined at P 1000 IU/D). BMD was positively influenced by serum 25(OH)D. However, serum 25(OH) ≥100 nmol/L was associated with lower BMD (absolute and T-scores) for whole-body and spine (P ≤ 0.05). VitK1 intake (≥200 μg/day) was associated with higher whole-body and femoral-neck BMDs (absoluteand T-scores; P ≤ 0.05). VitD status and BMD in adults with DM and CKD was influenced by vitD supplementation and vitK1 intake.

    Full Text Available Introduction & Objective: Evidences have indicated that the Ventral Tegmental Area (VTA is the major source of dopamine (DA neurons projecting to cortical and limbic regions involved in cognitive and motivational aspects of addiction. Also, studies have indicated that the Ascorbic acid (vitamin C can reduce the dependency symptoms of opioids such as morphine via effect of activity on dopaminergic neuron in VTA. For this reason, the aim of this study was to assess the effects of ascorbic acid on the amplitude of Ventral Tegmental Area field action potential in morphine-exposed rats. Materials & Methods: Forty male Wistar’s rats were used in this experimental study conducted at Yasuj University of Medical Sciences in 2010. Animals were randomly divided into four groups after electrode implantation and recovery period: 1. No- Vit C and No-Addicted group (nVitC.nA 2. Vit C and No-Addicted group (VitC.nA 3. No- Vit C and Addicted group (nVitCA 4.Vit C and Addicted (VitC.A, The Vit C groups received 500 mg/kg of Vit C during 20 days. For addicted groups morphine was administrated once daily for 20 days. In the 20th day, the field potential recording was accomplished. Two-way ANOVA was used for data analysis followed by the Tukey test for post hoc analysis. Results were considered significant at P < 0.05. Results: This study shows the exposure to morphine declined the power of Delta and Beta bands (p<0.05 and Vit C solely enhance power of Theta and Beta (p<0.05, p<0.001 in VTA nuclei. Furthermore, Vit C could alter power of some bands which were affected by morphine. Therefore it seems that Vit C has an increasing effects on them (p<0.05. Conclusion: Although the effect of Vit C on power of the VTA bands is not well known, but it is supposed that this phenomenon can be related to alteration in activity of dopaminergic neuron in the brain.

    Full Text Available Vitamin D (VitD, although originally described as an essential hormone for bone and mineral homeostasis, appears to have an active role in regulating specific facets of human immunity. Indeed, VitD has been shown to have significant effects on cytokine production and lymphocyte proliferation. Evidence that VitD affects clearance of selected pathogens is supported by epidemiological and clinical data, while its coadministration with influenza vaccine in mice enhanced both mucosal and systemic antibody responses. This paper aims to examine how VitD may contribute to limiting the burden of influenza infection in the aging and aged adults, a population in which this burden remains considerable. Furthermore, we discuss how VitD status may play a role in host resistance to influenza virus and influence the immunogenicity of the influenza vaccines currently licensed for adults aged 65 years or over by its effects on innate and adaptive immunities.

    Monitoring of adverse drug reactions of a drug is a continuous process and runs through-out the life of a drug. Many rare adverse effects of a drug are documented after years of use; when a single case (signal generation) is reported leading subsequently to reporting of more cases. Deficiency of Vitamin B12 (vit B(12)) is a known sequel of prolonged metformin therapy. It was recommended to have annual measurement of serum vit B(12) levels in patients on long term metformin therapy way back in 1970 itself. After more than 50 years of use of metformin, we have come to know that metformin induced vit B(12) deficiency can cause neuropathy; forcing to change the recommendation from annual screening of vit B(12) levels to annual supplementation of vit B(12).

    The effects of vitamin E (Vit E) on brain derived neurotrophic factor (BDNF) and brain tissues oxidative damage as well as on learning and memory impairments in juvenile hypothyroid rats were examined. The rats were grouped as: (1) Control; (2) Propylthiouracil (PTU); (3) PTU-Vit E and (4) Vit E. PTU was added to their drinking water (0.05%) during 6 weeks. Vit E (20 mg/kg) was daily injected (IP). Morris water maze (MWM) and passive avoidance (PA) were carried out. The animals were deeply anesthetized and the brain tissues were removed for biochemical measurements. PTU increased the escape latency and traveled path in MWM (P E (P E improved BDNF, thiol, SOD and CAT while diminished MDA. The results of the present study showed that Vit E improved BDNF and prevented from brain tissues oxidative damage as well as learning and memory impairments in juvenile hypothyroid rats.

    Patients with mastocytosis and wasp venom allergy (WA) may benefit from venom immunotherapy (VIT). However, fatal insect sting reactions have been described in mastocytosis patients despite previous immunotherapy. We investigated the safety and efficacy of (rush) VIT in patients with mastocytosis and WA. To investigate the safety and efficacy of (rush) VIT in patients with mastocytosis and WA. We describe nine patients with cutaneous mastocytosis and WA who received VIT. Cutaneous mastocytosis was confirmed by histopathology and systemic mastocytosis was diagnosed according to World Health Organization criteria. VIT was given according to a rush protocol. Given the difference in safety and efficacy of VIT in patients with WA and honeybee venom allergy, we reviewed the literature for VIT with the focus on WA patients with mastocytosis and addressed the difference between patients with cutaneous versus systemic mastocytosis. Nine patients had WA and mastocytosis, of whom six had cutaneous mastocytosis, two combined cutaneous and systemic mastocytosis and one systemic mastocytosis. All patients received rush IT with wasp venom. Most patients had only mild local side effects, with no systemic side effects during the course of VIT. One patient had a systemic reaction upon injection on one occasion, during the updosing phase, with dyspnoea and hypotension, but responded well to treatment. Immunotherapy was continued after temporary dose adjustment without problems. Two patients with a previous anaphylactic reaction were re-stung, without any systemic effects. VIT is safe in cutaneous mastocytosis patients with WA, while caution has to be made in case of systemic mastocytosis. VIT was effective in the patients who were re-stung.

    Full Text Available The study was designed to investigate the effects of dietary Selenium-enriched radish sprouts (Se-RS, Vitamin E (Vit E, and Rhodobacter capsulatus (RC on immunity, cholesterol concentration, and fatty acid composition in broiler meat. A total of 100 two-week-old male broiler chicks were randomly assigned into five dietary groups: I Control; II Se-RS (5 μg/kg Se-RS; III Se-RS+RC (5 μg/kg Se-RS + 0.2 g/kg RC; IV Se-RS+Vit E (5 μg/kg Se-RS + 50 mg/kg Vit E and V Se-RS+RC+Vit E (5 μg/kg Se-RS + 0.2 g/kg RC + 50 mg/kg Vit E. Diets and clean drinking water were offered ad libitum. After the end of 3-wk of feeding period, serum cholesterol and triglycerides concentrations were lower (P < 0.05 in broilers fed Se-RS + RC + Vit E supplemented diet compared to the control diet. At the end of the 6-wk feeding period, birds fed the Se-RS+RC+Vit E diet significantly (P < 0.05 reduced cholesterol and triglycerides concentrations and improved the ratio of unsaturated fatty acids to saturated fatty acids in broiler meat. The highest (P < 0.05 number of leukocytes was observed in broilers fed Se-RS+RC+Vit E supplemented diet. Foot web index and weights of spleen, bursa, and thymus were significantly (P < 0.05 higher in birds fed Se-RS+RC+Vit E compared to the control diet. Our findings suggest that there are dual benefits of supplementing broiler diets with Se-RS+RC+Vit E because of improvements in the bird’s immunity and meat quality that is important for health conscious consumers.

    Vitamin C (vitC) is essential for normal pregnancy and fetal development and poor vitC status has been related to complications of pregnancy. We have previously shown lower vitC status in diabetic women throughout pregnancy compared to that of non-diabetic controls. Here, we evaluate the relationship between vitC status late in diabetic pregnancy in relation to fetal outcome, complications of pregnancy, diabetic characteristics, and glycemic control based on data of 47 women from the same cohort. We found a significant relationship between the maternal vitC level > or ≤ the 50% percentile of 26.6 μmol/L, respectively, and the umbilical cord blood vitC level (mean (SD)): 101.0 μmol/L (16.6) versus 78.5 μmol/L (27.8), p = 0.02; n = 12/16), while no relation to birth weight or Apgar score was observed. Diabetic women with complications of pregnancy had significantly lower vitC levels compared to the women without complications (mean (SD): 24.2 μmol/L (10.6) vs. 34.6 μmol/L (14.4), p = 0.01; n = 19 and 28, respectively) and the subgroup of women (about 28%) characterized by hypovitaminosis C (complications of pregnancy that was 2.4 fold higher than the one found in the group of women with a vitC status above this level (p = 0.02, 95% confidence interval 1.2-4.4). No correlation between diabetic characteristics of the pregnant women and vitC status was observed, while a negative association of maternal vitC with HbA1c at delivery was found at regression analysis (r = -0.39, p complications of pregnancy.

    Full Text Available Introduction: Vitamin D (VitD classically recognized for its role in the musculoskeletal system, has been implicated in myriad of conditions such as diabetes, immune dysfunction, cancers, heart disease, metabolic syndrome, etc. We studied the role of VitD in acute care setting and its correlation with mortality. Materials and Methods: A total of 85 consecutive consenting patients admitted in medical intensive care unit of tertiary care hospital who fulfilled the inclusion criteria were included. All patients were evaluated clinically, and blood samples were collected for hemogram, biochemical investigations including serum calcium, phosphorus, alkaline phosphatase, magnesium, along with 25(OH VitD, 1,25(OH VitD and intact parathormone levels. Simplified acute physiology score (SAPS II was calculated for all patients. Results: VitD was deficient (<30 ng/ml in 27 patients (32%. The overall mortality was more in VitD deficient group as compared to VitD sufficient group (74 vs. 41%; P < 0.05. The actual mortality in VitD deficient group was higher than the mortality predicted by SAPS II score (50 vs. 74%; P < 0.0507. VitD deficiency was also associated with more mortality among those requiring ventilator support (95% vs. 40%; P < 0.05 as well as with higher blood glucose (124.5 ± 29.7 vs. 94.8 ± 19.8: P < 0.01 levels. Conclusion: VitD deficiency was associated with increased mortality, poor ventilator outcomes, and increased blood glucose in critically ill patients.

    Vitamin D (vit D) has anti-inflammatory properties and modulates lung growth, but whether vit D can prevent lung injury after exposure to antenatal inflammation is unknown. We hypothesized that early and sustained vit D treatment could improve survival and preserve lung growth in an experimental model of bronchopulmonary dysplasia induced by antenatal exposure to endotoxin (ETX). Fetal rats (E20) were exposed to ETX (10 μg), ETX + Vit D (1 ng/ml), or saline (control) via intra-amniotic (IA) injections and delivered 2 days later. Newborn pups exposed to IA ETX received daily intraperitoneal injections of vit D (1 ng/g) or saline for 14 days. Vit D treatment improved oxygen saturations (78 vs. 87%; P < 0.001) and postnatal survival (84% vs. 57%; P < 0.001) after exposure to IA ETX compared with IA ETX alone. Postnatal vit D treatment improved alveolar and vascular growth at 14 days by 45% and 25%, respectively (P < 0.05). Vit D increased fetal sheep pulmonary artery endothelial cell (PAEC) growth and tube formation by 64% and 44%, respectively (P < 0.001), and prevented ETX-induced reductions of PAEC growth and tube formation. Vit D directly increased fetal alveolar type II cell (ATIIC) growth by 26% (P < 0.001) and enhanced ATIIC growth in the presence of ETX-induced growth suppression by 73% (P < 0.001). We conclude that antenatal vit D therapy improved oxygenation and survival in newborn rat pups and enhanced late lung structure after exposure to IA ETX in vivo, which may partly be due to direct effects on vascular and alveolar growth.

    Venom immunotherapy (VIT) is a treatment with established efficacy for the prevention of repeated anaphylactic reactions in patients with Hymenoptera allergy, which also allows patients to discontinue carrying an EpiPen. Despite their merits, both treatments can have negative aspects potentially important to patients. We examined possible negative aspects of the EpiPen in comparison with VIT as perceived by patients. Positive and negative aspects of both treatments were measured by using a burden of treatment questionnaire together with statements about the EpiPen. One hundred ninety-three patients were included, of whom 94 consented to randomization: 47 received VIT, and 47 received the EpiPen. Of the remaining 99, 75 chose VIT, and 26 chose the EpiPen. Of the patients receiving VIT, 91.5% were (extremely) positive about their treatment, and 85% would choose VIT again. Of the patients receiving the EpiPen, only 48% were positive about their treatment, and even of these patients, 68% preferred to be treated with VIT after 1 year of carrying the EpiPen. Although most patients indicated that it is reassuring to carry an EpiPen and makes them feel safe, many patients also indicated that it is inconvenient and troublesome. Especially patients who were negative about the EpiPen indicated that they would not dare use the EpiPen if necessary and were afraid at possible side effects. In contrast to VIT, the EpiPen is perceived as burdensome by most patients with venom allergy. For most patients, an EpiPen is an unsuitable definitive treatment. As VIT enables patients with venom allergy to get rid of the EpiPen, patients should be offered VIT.

    Venom immunotherapy (VIT) is effective in preventing anaphylactic reactions after insect stings. The effect of VIT on health-related quality of life (HRQL) was studied to evaluate whether this treatment is of importance to patients. We compared HRQL outcomes measured with a disease-specific instrument (Vespid Allergy Quality-of-Life Questionnaire [VQLQ]) in patients allergic to yellow jacket venom treated with VIT or with an adrenalin self-administration device (EpiPen) in an open-label, randomized, controlled trial. Consenting patients were block randomized to either VIT or EpiPen. Patients received uniform, standardized information, which specified the risk of their condition and the risks and benefits of both treatment options. HRQL measures took place before and after 1 year of treatment with VIT or EpiPen. Seventy-four patients agreed to be randomized, of whom 36 received VIT and 38 an EpiPen. The mean change in VQLQ score in the group randomized to VIT was 1.07 (95% CI, 0.68-1.46), and this improvement was statistically significant (P EpiPen, in which this change was -0.43 (95% CI, -0.71 to -0.16). These differences were seen in both men and women, persons with more or less general anxiety, and those stung recently and those stung more than a year before their outpatient department visit. The overall proportion of patients receiving benefit from VIT is 0.72, generating a number needed to treat of 1.4. VIT results in a clinically important improvement in HRQL in patients allergic to yellow jacket venom in all subgroups studied. Of every 3 patients treated with VIT, 2 patients experience an important improvement in their quality of life.

    Full Text Available With the increasing recognition of the importance of the non-skeletal effects of vitamin D (VitD, more and more attention has been drawn to VitD status in early life. However, the VitD status of newborns and factors that influence VitD levels in Shanghai, China, remain unclear. A total of 1030 pregnant women were selected from two hospitals in Shanghai, one of the largest cities in China located at 31 degrees north latitude. Umbilical cord serum concentrations of 25-hydroxy vitamin D [25(OHD] were measured by LC-MS-MS, and questionnaires were used to collect information. The median cord serum 25(OHD concentration was 22.4 ng/mL; the concentration lower than 20 ng/mL accounted for 36.3% of the participants, and the concentration lower than 30 ng/mL for 84.1%. A multivariable logistic regression model showed that the determinants of low 25(OHD status were being born during autumn or winter months and a lack of VitD-related multivitamin supplementation. The relative risk was 1.7 for both autumn (95% CI, 1.1–2.6 and winter (95% CI, 1.1–2.5 births (p < 0.05. VitD-related multivitamin supplementation more than once a day during pregnancy reduced the risk of VitD deficiency [adjusted OR (aOR = 0.6, 95% CI (0.45–1.0 for VitD supplementation] (p < 0.05. VitD deficiency and insufficiency are common in newborns in Shanghai, China, and are independently associated with season and VitD supplementation. Our findings may assist future efforts to correct low levels of 25(OHD in Shanghai mothers and their newborn children.

Oxidative stress parameters such as total antioxidant capacity, glutathione, malondialdehyde, protein hydroperoxide, multivitamins such as L-ascorbic acid (Vit C, retinoic acid (Vit A, and tocopherol (Vit E, and the lipid profile parameters such as cholesterol, triglyceride, high-density lipoprotein-cholesterol (HDL-C and low-density lipoprotein-cholesterol (LDL-C were analyzed. Moreover, Vit C, Vit A, and Vit E levels were evaluated in the star fruit extracts during the 4-week period.Results: In the 2-week control period, all parameters showed no statistically significant difference; after 4 weeks of consumption, significant improvement in the antioxidant status was observed with increased total antioxidant capacity and reduced malondialdehyde and protein hydroperoxide levels, as well as significantly increased levels of Vit C and Vit A, when compared to the two-time evaluation during the baseline periods. However, glutathione and Vit E showed no statistical difference. In addition

    Obesity is a major public health problem and great risk for not only cardiovascular diseases but also cancer, musculoskeletal, and gynecological diseases. This study was aimed to investigate the association between serum Vitamin B12 (vitB12), body mass index (BMI), and nutritional status among obese women. This cross-sectional study enrolled consecutive female subjects. The consumptions of red meat, fish, bovine liver, egg, and mushroom were recorded. According to the Dietary Reference Intakes, the patients were categorized as insufficiency and sufficiency. Three cutoff points were defined for vitB12 status: (1) Deficiency if vitB12 is <200 pg/mL; (2) insufficiency if vitB12 is 250-350 pg/mL, and (3) sufficient if vitB12 is ≥350 pg/mL. According to BMI, the patients were assigned to nonobese and obese groups. BMI, serum vitB12 level, consumptions of red meat, fish, bovine liver, egg, and mushroom were evaluated and compared between two groups. Mean level of vitB12 was 247.8 ± 10.4 pg/mL and significantly associated with consumption of egg (P = 0.031), bovine liver (P = 0.004), mushroom (P = 0.040), and red meat (P = 0.003). VitB12 was significantly higher in nonobese than obese group (282.5 ± 106.8 vs. 242.5 ± 107.5 pg/mL, P = 0.001). The ratio of vitB12 deficiency was significantly higher in obese than nonobese group (37.6% vs. 24.7%; P = 0.019). VitB12 level was negatively correlated with BMI (r = -0.155; P< 0.001), but not insulin resistance (r = -0.172; P = 0.062). Obesity was associated with low level of vitB12 in obese women, and more likely to be vitB12 deficient. Consumption of certain types of food contributes to increase vitB12 level.

    Asthma is a common disease in the world and vitamin D (Vit-D) has been associated with the presence and severity of this disease. To establish the association between levels of Vit-D and IgE response in schoolchildren with asthma living in four cities in Colombia. Case-control study in 1340 schoolchildren (687 asthmatic and 653 controls) from communities in extreme poverty in Barranquilla, Cartagena, Santa Marta, and Montería. Serum concentrations of Vit-D, total IgE, and anti-Dermatophagoides farinae, Periplaneta americana, and Ascaris lumbricoides (AL) specific IgE were measured. Controls reported higher concentrations of Vit-D [61.9 ± 28.4 ng/mL] than cases [53 ± 23.3 ng / mL] (p < 0.05). Total IgE was higher in cases (p < 0.05). Only anti-AL IgE showed a clear difference: in controls, optical density was 0.27 ± 0.25; in cases, 0.22 ± 0.24 (p < 0.05). Vit-D showed differences between cases and controls in each population. An association could not be demonstrated between Vit-D deficiency and asthma, as total IgE was elevated in patients and controls. The results suggest that Vit-D influences the specif IgE response in poor asthmatic children in areas endemic for helminthiasis.

    Administration of the neurosteroid progesterone (PROG) has been shown to be beneficial in a number of brain injury models and in two recent clinical trials. Given widespread vitamin D deficiency and increasing traumatic brain injuries (TBIs) in the elderly, we investigated the interaction of vitamin D deficiency and PROG with cortical contusion injury in aged rats. Vitamin D deficient (VitD-deficient) animals showed elevated inflammatory proteins (TNFα, IL-1β, IL-6, NFκB p65) in the brain even without injury. VitD-deficient rats with TBI, whether given PROG or vehicle, showed increased inflammation and greater open-field behavioral deficits compared to VitD-normal animals. Although PROG was beneficial in injured VitD-normal animals, in VitD-deficient subjects neurosteroid treatment conferred no improvement over vehicle. A supplemental dose of 1,25-dihydroxyvitamin D(3) (VDH) given with the first PROG treatment dramatically improved results in VitD-deficient rats, but treatment with VDH alone did not. Our results suggest that VitD-deficiency can increase baseline brain inflammation, exacerbate the effects of TBI, and attenuate the benefits of PROG treatment; these effects may be reversed if the deficiency is corrected.

    An alkyl polyglycoside (APG) surfactant was used in ultrasonic-assisted extraction to effectively extract vitexin-2″-O-rhamnoside (VOR) and vitexin (VIT) from Crataegus pinnatifida leaves. APG0810 was selected as the surfactant. The extraction process was optimized for ultrasonic power, the APG concentration, ultrasonic time, soaking time, and liquid-solid ratio. The proposed approach showed good recovery (99.80-102.50% for VOR and 98.83-103.19% for VIT) and reproducibility (relative standard deviation, n=5; 3.7% for VOR and 4.2% for VIT) for both components. The proposed sample preparation method is both simple and effective. The use of APG for extraction of key herbal ingredients shows great potential. Ten widely used commercial macroporous resins were evaluated in a screening study to identify a suitable resin for the separation and purification of VOR and VIT. After comparing static and dynamic adsorption and desorption processes, HPD100B was selected as the most suitable resin. After column adsorption and desorption on this resin, the target compounds VOR and VIT can be effectively separated from the APG0810 extraction solution. Recoveries of VOR and VIT were 89.27%±0.42% and 85.29%±0.36%, respectively. The purity of VOR increased from 35.0% to 58.3% and the purity of VIT increased from 12.5% to 19.9%.

    Organophosphorus insecticides may induce oxidative stress leading to the generation of free radicals and alteration in the antioxidant system. The aim of this study was to examine the potency of Dimethoate (Dim) to induce oxidative stress response in human erythrocyte in vitro and the role of Vitamins C (Vit C) and E (Vit E) in alleviating the cytotoxic effects. Erythrocytes were divided into three groups. The first group, erythrocytes were incubated for 4 h at 37 °C with different concentrations (0, 20, 40, 60, 80, and 100 mM) of Dim. The second and third groups were preincubated with Vit C or Vit E, respectively, for 30 min and followed by Dim incubation for 4 h at 37 °C. Following in vitro exposure, Dim caused a significant increase in malondialdehyde (MDA) levels, superoxide dismutase (SOD), and catalase (CAT) in erythrocytes at different concentrations. Vit E or Vit C pretreated erythrocytes showed a significant protection against the cytotoxic effects inducted by Dim on the studied parameters. In conclusion, antioxidant Vit E and C could protect against Dim-induced oxidative stress by decreasing lipid peroxidation and hyperactivity of SOD and CAT in human erythrocytes.

    Full Text Available Low vitamin D is involved in allergic asthma and rhinitis. IL-31 and IL-33 correlate with Th2-associated cytokines in allergic disease. We investigated whether low vitamin D is linked with circulating IL-31 and IL-33 in children with allergic disease of the airways. 25-Hydroxyvitamin D [25(OH Vit D], IL-31, and IL-33 plasma levels were measured in 28 controls (HC, 11 allergic rhinitis (AR patients, and 35 allergic asthma with rhinitis (AAR patients. We found significant lower levels of 25(OH Vit D in AR and in AAR than in HC. IL-31 and IL-33 plasma levels significantly increased in AAR than HC. IL-31 and IL-33 positively correlated in AR and AAR. 25(OH Vit D deficient AAR had higher levels of blood eosinophils, exacerbations, disease duration, and total IgE than patients with insufficient or sufficient 25(OH Vit D. In AAR 25(OH Vit D levels inversely correlated with total allergen sIgE score and total atopy index. IL-31 and IL-33 did not correlate with 25(OH Vit D in AR and AAR. In conclusion, low levels of 25(OH Vit D might represent a risk factor for the development of concomitant asthma and rhinitis in children with allergic disease of the airways independently of IL-31/IL-33 Th2 activity.

    Full Text Available Objectives. To assess zinc (Zn and vitamin D (Vit. D status in chronic Hepatitis C virus- (HCV infected patients and their relationship to interleukin- (IL- 17 and disease severity and then investigate whether Zn and Vit. D3 modulate IL-17 expression in chronic HCV patients. Methods. Seventy patients and fifty healthy subjects were investigated. Serum levels of Zn, Vit. D, and IL-17 were assessed in the patients group and subgroups. Patients lymphocytes were activated in vitro in the presence or absence of Zn or Vit. D3 and then intracellular IL-17 production was assessed using flow cytometry. Results. Zn and Vit. D were significantly decreased in HCV patients. Increasing disease severity leads to more reduction in Zn level opposed by increasing IL-17 level. Zn potently reduced IL-17 production in a dose-related fashion; however it did not exert any toxic effects. Although Vit. D apparently increases IL17 expression, it is unclear whether it is due to its toxic effect on cell count or lack of definite association between Vit. D and both IL-17 and disease severity. Conclusions. This study demonstrates that Zn modulates IL-17 expression and provides a rationale for evaluating this compound as a supplementary agent in the treatment of chronic HCV.

    Hymenoptera venom anaphylaxis is a frightening event that affects physical and psychical functioning. Retrospective survey of 182 Hymenoptera venom allergic patients living in a rural area using a questionnaire targeting on patients' satisfaction during therapy, fear of anaphylactic recurrences and changes in lifestyle before and after venom immunotherapy (VIT). Additionally, patients' self-assessment of quality of life, daily outdoor time and re-sting rate were recorded. 146 patients returned the questionnaire (58.9% male, 41.1% female, 25.3% honey bee allergic, 67.8% wasp allergic, 41.1% re-sting rate, mean follow-up time 6.5 years). Measurement of the parameters fear, satisfaction and changes in lifestyle revealed a significant improvement after VIT. This correlated with the patients'self-assessment of quality of life,when 89.7% declared an improvement after VIT. Although the improvement was higher in patients with re-stings, also patients without re-stings clearly benefited from VIT. Interestingly, females were significantly more affected by Hymenoptera venom allergy than males,whereas both genders showed a similar improvement after VIT. Patients with Hymenoptera venom sting allergy significantly benefit from VIT in regard to both biological and psychological outcome. VIT should still be provided to all Hymenoptera venom allergic patients as standard of care.

    Full Text Available Background: Diazinon (DZN is an organophosphate insecticide widely utilized in agriculture all over the world and causes many negative effects on plants and animal species, especially on human. The aim of present study was to evaluate the effects of DZN on apoptosis of ovarian follicles in adult rats and to assess the protective role of vit E. Methods: Thirty adult female Wistar rats were divided into five groups: control group (without any intervention, sham group (received only pure olive oil, as solvent, experimental group 1 (DZN+olive oil, 60 mg/kg, experimental group 2 (vit E, 200 mg/kg, and experimental group 3 (DZN+vit E, the same dosage. All drugs were injected intraperitoneally, except vit E administrated by gavage. The animals were scarified after two weeks and left ovary was used to measure apoptosis of ovarian follicles. Results: The number apoptotic cells experimental group 1 increased significantly in contrast control group in secondary and graffian follicles (P< 0.001. Administration vit E plus DZN, significantly reduced apoptotic cells compared to DZN group (P< 0.001. Conclusion: DZN-induced apoptosis in secondary and graffian follicles and vit E inhibited apoptosis induced by DZN. Vit E might have a protective effect on DZN-induced ovarian toxicity.

    Poor vitamin D (vitD) status is linked to increased risk of infectious diseases, thus there is need for vitD-rich foods. UVB-exposed mushrooms synthesize vitD₂ but knowledge of bioavailability and function in immune response is lacking. One hundred rats were fed one of five diets--control, 20 IU vitD₃/day; no vitD₃/day; 5% unexposed mushroom, 2.4 IU vitD₂/day; 2.5% UVB mushroom, 300 IU vitD₂/day; and 5% UVB mushroom, 600 IU vitD₂/day--for 10 wk and challenged with either saline or the endotoxin LPS. Blood and tissues were collected at 3 h postchallenge. Plasma 25-hydroxyvitamin D (25OHD) levels from UVB-exposed mushroom fed rats were significantly elevated and associated with higher natural killer cell activity and reduced plasma inflammatory response to LPS compared to control diet fed rats. Microarray evaluation of rat spleens for changes in inflammatory gene expression showed significant upregulation of proinflammatory genes after LPS compared to saline controls in all groups. However, compared to control rats, upregulation of the proinflammatory genes was markedly reduced in the groups fed vitD₂-enriched mushrooms. Rats fed UVB-exposed mushrooms had significantly higher plasma total 25OHD levels that were associated with increased innate immune response and anti-inflammatory effects.

    Venom immunotherapy (VIT) induces immune tolerance to Hymenoptera venom but the underlying mechanisms are not clarified. Regulatory T cells are thought to play an important role in tolerance induction during specific immunotherapy. Our objective was to determine the effects of rush VIT on the percentage of regulatory T cells and immunosuppressive cytokines interleukin (IL)-10 and transforming growth factor beta (TGF-beta) in children. Blood samples were collected from 18 children with a previous systemic allergic reaction to a Hymenoptera sting, with a positive skin test and positive specific IgE, before rush VIT, after 6 weeks and 6 months of rush VIT. Ten children with no history of venom allergy were studied as controls. Isolated peripheral blood mononuclear cells were stained with specific markers for regulatory T cells and analyzed by flow cytometry. The percentage of regulatory T cells did not change during rush VIT in children. No change was noticed in the percentage of IL-10 and TGF-beta secreting cells after 6 weeks or 6 months of VIT. No difference in expression of cytotoxic T-lymphocyte antigen 4 on CD4(+)CD25(+high) was found. Rush VIT is a safe and effective treatment for patients allergic to Hymenoptera venom. Although regulatory T cells are considered to be responsible for this effect; no significant changes in the percentage of these cells or immunosuppressive cytokines were noticed during rush VIT in children. Additional investigations are needed to clarify the role of regulatory T cells in the induction of tolerance during rush VIT in children.

    This study aims to observe whether the combined treatment with vitamin E (vit E) and omega-3 polyunsaturated fatty acids (Ω-3 FA) could prevent the fine particulate matter (PM2.5)-induced cardiovascular injury through alleviating inflammation and oxidative stress. At the same time, the appropriate combination dosage of vit E and Ω-3 FA was explored to find an optimized protective dose to protect the injury induced by PM2.5. The SD rats were pretreated with different concentration of vit E and Ω-3 FA separately or jointly. Then the rats were exposed to ambient PM2.5 by intratracheal instillation for three times. The expression of tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) in serum and supernatant of cardiac tissue were detected by ELISA kits. The levels of malondialdehyde (MDA), superoxide Dismutase (SOD) and glutathione-peroxidase (GSH-Px) in myocardium and the level of MDA in serum were measured. Meanwhile, the cardiac injury was evaluated by histopathological examination. Compared with the severe injury of rats in PM2.5 exposure group, the rats in vit E or Ω-3 FA-pretreated groups had a slighter injury in heart. Meanwhile, pretreatment with vit E or Ω-3 FA induced a significantly alleviation of the inflammatory cytokines (TNF-α, IL-1β, IL-6) and the elevation of the anti-oxidative activity especially in the rats pretreated with combined vit E and Ω-3 FA. In addition, the combined protecting effects of vit E and Ω-3 FA showed a dose-dependent manner. Supplementation with vit E and Ω-3 FA could protect the PM2.5-induced injury, and the combination of vit E and Ω-3 FA might produce more effective effects than the separate nutrient did.

    In this study the effects of Vitamin C (Vit C) on hypothyroidism-associated learning and memory impairment in juvenile rats was investigated. The pregnant rats were kept in separate cages. After delivery, they were randomly divided into six groups and treated: (1) Control; (2) Propylthiouracil (PTU) which 0.005% PTU in their drinking; (3-5) Propylthiouracil- Vit C groups; besides PTU, dams in these groups received 10, 100 and 500 mg/kg Vit C respectively, (6) one group as a positive control; the intact rats received an effective dose, 100 mg/kg Vit. C. After delivery, the pups were continued to receive the experimental treatments in their drinking water up to 56th day of their life. Ten male offspring of each group were randomly selected and tested in the Morris water maze (MWM) and passive avoidance (PA) which were started at 63th day (one week after stopping of the treatments). Brains were then removed for biochemical measurements. PTU increased time latency and traveled distance during 5 days in MWM while, reduced the spent time in target quadrant in MWM and step-trough latency (STL) in PA. PTU decreased thiol content, superoxide dismutase (SOD) and catalase (CAT) activities in the brain while, increased molondialdehyde (MDA). In MWM test, 10, 100 and 500 mg/kg Vit C reduced time latency and traveled distance without affecting the traveling speed during 5 days. All doses of Vit C increased the spent time in target quadrant in probe trail of MWM and also increased STL in PA test. Vit C increased thiol, SOD and CAT in the brain tissues while, reduced MDA. Results of present study confirmed the beneficial effects of Vit C on learning and memory. It also demonstrated that Vit C has protective effects on hypothyroidism-associated learning and memory impairment in juvenile rats which might be elucidated by the antioxidative effects.

    Full Text Available Background: In recent publications, several mechanisms have been implicated in gentamicin (GM nephrotoxicity. Reactive oxygen species have been proposed as one of the causative factors of the drug renal side effects. This study was designed to evaluate the protective effects of the antioxidant vitamins against GM-mediated nephropathy in insitu isolated rat kidneys. Methods: Male Sprague-Dawley rats were randomly assigned to one of the following groups of seven rats: Group 1 (control was tyrode perfused kidneys. Group 2 (GM, 200µg/ml gentamicin was added to the perfusate. Group 3 (GM + Vit C, the same as group 2 but vitamin C (200 mg/L was added to the drinking water for 3 days and 100 mg/L to the perfusate. Group 4 (GM + Vit E, the same as group 2 but vitamin E (100 mg/100 g BW, ip was injected 12 h before experiments. Group 5 (GM + Vit C + Vit E the same as group 2 but Vit E and C were co-administered (same as Group 3 & 4. Urinary N-acetyle-B-D-glucosaminidas (NAG and renal cortex superoxide dismutase (SOD levels were measured and tissue histological evaluations were performed. Results: Gentamicin caused a significant nephrotoxicity demonstrated by increase in urinary NAG. Decline in SOD contents were observed comparing to controls. Vit C or Vit E inhibited the gentamicin-induced increased releases of NAG into urine but did not show a significant effect on the SOD levels. Conclusion: Co-administration of VitC&E significantly prevented the GM nephrotoxicity demonstrating by preservation of SOD levels and prevention of increase in urinary enzyme activities. Histological studies of renal tissues provided additional evidences for protective effects of antioxidant vitamins. We concluded that moderate doses of Vit C & E have protective effects in gentamicin nephrotoxicity and co-administration of these vitamins have additional beneficial effects.

    Full Text Available While having the highest vitamin C (VitC concentrations in the body, specific functions of VitC in the brain have only recently been acknowledged. We have shown that postnatal VitC deficiency in guinea pigs causes impairment of hippocampal memory function and leads to 30% less neurons. This study investigates how prenatal VitC deficiency affects postnatal hippocampal development and if any such effect can be reversed by postnatal VitC repletion. Eighty pregnant Dunkin Hartley guinea pig dams were randomized into weight stratified groups receiving High (900 mg or Low (100 mg VitC per kg diet. Newborn pups (n = 157 were randomized into a total of four postnatal feeding regimens: High/High (Control; High/Low (Depleted, Low/Low (Deficient; and Low/High (Repleted. Proliferation and migration of newborn cells in the dentate gyrus was assessed by BrdU labeling and hippocampal volumes were determined by stereology. Prenatal VitC deficiency resulted in a significant reduction in postnatal hippocampal volume (P<0.001 which was not reversed by postnatal repletion. There was no difference in postnatal cellular proliferation and survival rates in the hippocampus between dietary groups, however, migration of newborn cells into the granular layer of the hippocampus dentate gyrus was significantly reduced in prenatally deficient animals (P<0.01. We conclude that a prenatal VitC deficiency in guinea pigs leads to persistent impairment of postnatal hippocampal development which is not alleviated by postnatal repletion. Our findings place attention on a yet unrecognized consequence of marginal VitC deficiency during pregnancy.

    Full Text Available BACKGROUND: Treatment failure during venom immunotherapy (VIT may be associated with a variety of risk factors. OBJECTIVE: Our aim was to evaluate the association of baseline serum tryptase concentration (BTC and of other parameters with the frequency of VIT failure during the maintenance phase. METHODS: In this observational prospective multicenter study, we followed 357 patients with established honey bee or vespid venom allergy after the maintenance dose of VIT had been reached. In all patients, VIT effectiveness was either verified by sting challenge (n = 154 or patient self-reporting of the outcome of a field sting (n = 203. Data were collected on BTC, age, gender, preventive use of anti-allergic drugs (oral antihistamines and/or corticosteroids right after a field sting, venom dose, antihypertensive medication, type of venom, side effects during VIT, severity of index sting reaction preceding VIT, and duration of VIT. Relative rates were calculated with generalized additive models. RESULTS: 22 patients (6.2% developed generalized symptoms during sting challenge or after a field sting. A strong association between the frequency of VIT failure and BTC could be excluded. Due to wide confidence bands, however, weaker effects (odds ratios <3 of BTC were still possible, and were also suggested by a selective analysis of patients who had a sting challenge. The most important factor associated with VIT failure was a honey bee venom allergy. Preventive use of anti-allergic drugs may be associated with a higher protection rate. INTERPRETATION: It is unlikely that an elevated BTC has a strong negative effect on the rate of treatment failures. The magnitude of the latter, however, may depend on the method of effectiveness assessment. Failure rate is higher in patients suffering from bee venom allergy.

  5. Pharmacological preconditioning with vitamin C attenuates intestinal injury via the induction of heme oxygenase-1 after hemorrhagic shock in rats.

    Directory of Open Access Journals (Sweden)

    Bing Zhao

    Full Text Available Pre-induction of heme oxygenase (HO-1, which is regarded as an effective method of "organ preconditioning", exerts beneficial effects during hemorrhagic shock (HS. However, the available HO-1 inducers exhibit disadvantages such as toxicity or complex technical requirements. Therefore, a safe and convenient HO-1 inducer would be promising and could be exploited in the treatment of foreseeable hemorrhaging, such as prior to major surgery. Here we investigated the effect of vitamin C (VitC, a common antioxidant, on intestinal HO-1 expression and examined whether VitC pretreatment prevented HS related intestinal tissue injuries after HO-1 induction. First, we conducted an in vitro study and found that HO-1 expression in rat intestinal epithelial cells (IEC-6 was induced by non-toxic VitC in a time and concentration dependent manner, and the mechanism was related to the activation of extracellular signal-regulated kinase 1/2 (ERK1/2. Next, we conducted an in vivo study and found that VitC induced intestinal HO-1 protein expression (mainly observed in the intestinal epithelial cells and HO-1 activity in normal SD rats, and that these HO-1 levels were further enhanced by VitC in a rat model of HS. The HS related intestinal injuries, including histological damage, pro-inflammatory cytokine levels (tumor necrosis factor and interleukin-6, neutrophil infiltration and apoptosis decreased after VitC pretreatment, and this alleviating of organ injuries was abrogated after the inhibition of HO-1 activity by zinc protoporphyrin-IX. It was of note that VitC did little histological damage to the intestine of the sham rats. These data suggested that VitC might be applied as a safe inducer of intestinal HO-1 and that VitC pretreatment attenuated HS related intestinal injuries via the induction of HO-1.

    Methamphetamine (METH) is a drug of abuse which causes neurotoxicity and increased risk of developing neurodegenerative diseases. We previously found that METH induces heme oxygenase (HO)-1 expression in neurons and glial cells, and this offers partial protection against METH toxicity. In this study, we investigated the effects of L-ascorbate (vitamin C, Vit. C) on METH toxicity and HO-1 expression in neuronal/glial cocultures. Cell viability and damage were evaluated by 3-(4,5-dimethylthianol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) reduction and lactate dehydrogenase (LDH) release, respectively. Neuronal and glial localization of HO-1 were identified by double immunofluorescence staining. Reactive oxygen species (ROS) production was measured using the fluorochrome 2′,7′-dichlorofluorescin diacetate. HO-1 mRNA and protein expression were examined by RT-qPCR and Western blotting, respectively. Results show that Vit. C induced HO-1 mRNA and protein expressions in time- and concentration-dependent manners. Inhibition of p38 mitogen-activated protein kinase (MAPK) but not extracellular signal-regulated kinase (ERK) significantly blocked induction of HO-1 by Vit. C. HO-1 mRNA and protein expressions were significantly elevated by a combination of Vit. C and METH, compared to either Vit. C or METH alone. Pretreatment with Vit. C enhanced METH-induced HO-1 expression and attenuated METH-induced ROS production and neurotoxicity. Pharmacological inhibition of HO activity abolished suppressive effects of Vit. C on METH-induced ROS production and attenuated neurotoxicity. We conclude that induction of HO-1 expression contributes to the attenuation of METH-induced ROS production and neurotoxicity by Vit. C. We suggest that HO-1 induction by Vit. C may serve as a strategy to alleviate METH neurotoxicity. -- Highlights: ► Besides the anti-oxidant effect, Vit. C also induces HO-1 expression in brain cells. ► Vit. C reduces METH neurotoxicity and ROS production by

    Full Text Available Abstract Purpose Here, we studied the beneficial effects of aerobic exercise on metabolic syndrome components, cognitive performance, brain derived neurotrophic factor (BDNF and irisin in ovariectomized rats with different serum vitamin D (Vit D status. Methods Eighty female wistar rats were divided into 2 groups of sham operated (sham, n = 8, and ovariectomized (OVX, n = 72. Then OVX were divided into 9 groups of receiving combination of exercise protocol with low dose of Vit D (OVX + EXE + LD, high dose of Vit D (OVX + EXE + HD, Vit D deficiency (OVX + EXE − D, and (OVX + EXE + Veh. Also non exercised groups of OVX receiving high dose of Vit D (OVX + HD, low dose of Vit D (OVX + LD, Vit D deficiency (OVX − D, and Veh (OVX + Veh were included. After 2 months of related interventions, spatial memory was assessed using Morris water maze (MWM, and then metabolic syndrome components were measured. Results High dose of Vit D supplementation showed significant reduction in weight (p = 0.001, lipid profiles (p = 0.001, visceral fat (p = 0.001 and waist circumference (p = 0.001 regardless of exercising or not, with no change in cognitiive function. Serum BDNF level was significantly higher in Vit D deficient group (p = 0.001, and was decreased in the OVX + HD. In contrary, irisin did not show any significant relationship with serum concentration of Vit D, while it was significantly elevated in the exercised groups compared with non-exercised counterparts. Conclusion Vit D insufficiency deteriorates metabolic syndrome components, and elevates serum BDNF as a compensatory metabotropic factor, and further supplementation significantly attenuates these components parallel with reduction in BDNF. In addition, aerobic exercise successfully induces various metabolic benefits, provided optimum serum level of Vit D.

The hypothesis was that, like dairy cows, goats and sheep are able to compensate for the missing nutritional supply of vitD through endogenous production in the skin, with the consequence of a high vitD status and a balanced Ca homeostasis. Sixteen lambs and 14 goat kids aged 3 and a half months were housed in an UVB free environment and fed hay and a vitD-free concentrate over a period of 13 wk. One group of each species was exposed to UVB lamps daily during individual feeding; the other groups served as controls. Serum, urine, and feces samples were taken at the start and at a monthly interval. Serum was analyzed for vitD metabolites, bone markers, growth hormone, insulin-like growth factor I, Ca, and P. Apparent digestibility and urinary excretion of Ca and P were determined. The left metatarsus was analyzed by peripheral quantitative computer tomography for bone mineral density before starting and at the end of the trial. In wk 13, all animals were slaughtered and samples of skin, rumen, duodenum, kidney, and bone (metatarsus) were collected. Content of sterols of vitD synthesis in the skin, Ca flux rates in rumen and duodenum, expression of vitD receptor in duodenum and kidney, renal and intestinal gene expression of Ca transport proteins, and renal enzymes related to vitD metabolism were determined. The UVB exposure led to lower 7-dehydrocholesterol content in the skin and a better vitD status (higher serum 25-hydroxyvitamin D), but no signs of vitD deficiency were seen in the control groups and no effect of irradiation was detected in the analyzed parameters of Ca homeostasis. Differences between the 2 species were detected: lambs had a higher increase of bone mineral density, lower values of bone markers, growth hormone, and insulin-like growth factor I in

    Few data exist regarding the use of venom immunotherapy (VIT) in specific high-risk chronic medical conditions and pregnancy, and in young children. A Web-based survey was sent to American Academy of Asthma Allergy & Immunology members to explore their VIT experience in potential high-risk medical conditions and pregnancy, and in young children. Major problems were defined as "activation of underlying disease and/or VIT not well tolerated (systemic adverse events) and/or VIT discontinued for medical reasons." Results were expressed descriptively. A total of 697 of 5123 surveys (14%) were completed: 87% of the respondents were based in the United States, and 28% worked in an academic setting. Most respondents (71%) believed that pregnancy was a contraindication for starting VIT. Most were comfortable continuing VIT (51%) if the woman became pregnant after starting therapy. Of the allergists who treated children, many would give VIT down to age 5 years (42%) or younger, ages 1-4 years (35%). The following list is of the specific medical condition, the number of allergists who used VIT in patients with this condition, and the percentage who reported major problems: severe asthma, 212 (4.2%); hypertension, 287 (1.1%); coronary artery disease, 222 (3.6%); arrhythmias, 136 (3.4%); cerebrovascular disease, 104 (5.1%); cancer in remission, 166 (0%); cancer stable but still under treatment, 44 (7.2%); a history of bone marrow transplantation, 15 (4.9%); a history of solid organ transplantation, 29 (3.6%); human immunodeficiency virus, 53 (1.4%); acquired immunodeficiency syndrome, 24 (6.2%); stable autoimmune disease, 164 (2.8%); mastocytosis, 66 (18.4%); elevated serum tryptase, 101 (10.8%); immunodeficiency 59 (2.5%). Many allergists were comfortable using VIT in young children and continuing but not starting pregnant women on VIT. VIT was commonly used in patients with hypertension, coronary artery disease, arrhythmias, cancer in remission, and stable autoimmune disease

    The aim of the present study was to evaluate the effect of rosemary ( Rosmarinus officinalis L.) powder and vitamin E, as feed additives combined at different levels, on oxidative stability of broiler meat up to 14th day after chilling. A total of 270 1-day-old male chicks of Ross 308 strain were randomly assigned to nine dietary groups with three replicates having 10 birds each. Diets were supplemented with 0, 0.5, or 1.0% of rosemary (R) powder and 0, 100, or 200 mg/kg of vitamin E (alpha-tocopherol acetate; VitE) according to the following treatments: T1 - control basal diet (0R + 0VitE); T2 - 0R + 100VitE; T3 - 0R + 200VitE; T4 - 0.5R + 0VitE; T5 - 0.5R + 100VitE; T6 - 0.5R + 200VitE; T7 - 1.0R + 0VitE; T8 - 1.0R + 100VitE; and T9 - 1.0R + 200VitE.

    The establishment of staff canteens is expected to improve the nutritional situation of Cambodian garment workers. The objective of this study is to assess the nutritive value of low-price model lunch sets provided at a garment factory in Phnom Penh, Cambodia. Exemplary lunch sets were served to female workers through a temporary canteen at a garment factory in Phnom Penh. Dish samples were collected repeatedly to examine mean serving sizes of individual ingredients. Food composition tables and NutriSurvey software were used to assess mean amounts and contributions to recommended dietary allowances (RDAs) or adequate intake of energy, macronutrients, dietary fiber, vitamin C (VitC), iron, vitamin A (VitA), folate and vitamin B12 (VitB12). On average, lunch sets provided roughly one third of RDA or adequate intake of energy, carbohydrates, fat and dietary fiber. Contribution to RDA of protein was high (46% RDA). The sets contained a high mean share of VitC (159% RDA), VitA (66% RDA), and folate (44% RDA), but were low in VitB12 (29% RDA) and iron (20% RDA). Overall, lunches satisfied recommendations of caloric content and macronutrient composition. Sets on average contained a beneficial amount of VitC, VitA and folate. Adjustments are needed for a higher iron content. Alternative iron-rich foods are expected to be better suited, compared to increasing portions of costly meat/fish components. Lunch provision at Cambodian garment factories holds the potential to improve food security of workers, approximately at costs of <1 USD/person/day at large scale. Data on quantitative total dietary intake as well as physical activity among workers are needed to further optimize the concept of staff canteens.

    Venom immunotherapy (VIT) is considered to be the gold standard treatment for patients with hymenoptera venom allergy. This treatment induces systemic reactions (SR) in a significant number of patients. To evaluate the outcome of VIT in patients with known risk factors for VIT-induced SR and to compare rush VIT (RVIT) and conventional VIT (CVIT). All of the patients who received VIT and had at least one of the following risk factors were included: current cardiovascular disease, uncontrolled asthma, high basal serum tryptase, current treatment with β-blockers or angiotensin-converting enzyme inhibitors, and age >70 or <5 years. Sixty-four patients were included, and most of them (52; 81.5%) were allergic exclusively to bee venom. Thirty-five (54.7%) patients underwent RVIT and 29 CVIT. The incidence of patients who developed SR during the build-up phase was similar for RVIT and CVIT (25.7 and 27.5%, respectively; p = 1). However, the incidence of SR per injection was significantly higher in CVIT than in RVIT (5.6 and 2.75%, respectively; p = 0.01). Most reactions (79.1%) were mild, limited to the skin. Most of the patients (92.1%) reached the full maintenance dose of 100 μg. This dose was reached by a significantly larger number of patients receiving RVIT compared to CVIT (100 and 82.7%, respectively; p = 0.01). None of the patients experienced exacerbation of their concurrent chronic disease during VIT. VIT can be performed safely and efficiently in patients with risk factors for immunotherapy. In these patients RVIT appears to be safer and more efficient than CVIT. © 2017 S. Karger AG, Basel.

    The objective of this study was to evaluate the effects of different maturation systems on oocyte resistance after vitrification and on the phospholipid profile of the oocyte plasma membrane (PM). Four different maturation systems were tested: 1) in vitro maturation using immature oocytes aspirated from slaughterhouse ovaries (CONT; n = 136); 2) in vitro maturation using immature oocytes obtained by ovum pick-up (OPU) from unstimulated heifers (IMA; n = 433); 3) in vitro maturation using immature oocytes obtained by OPU from stimulated heifers (FSH; n = 444); and 4) in vivo maturation using oocytes obtained from heifers stimulated 24 hours prior by an injection of GnRH (MII; n = 658). A sample of matured oocytes from each fresh group was analyzed by matrix associated laser desorption-ionization (MALDI-TOF) to determine their PM composition. Then, half of the matured oocytes from each group were vitrified/warmed (CONT VIT, IMA VIT, FSH VIT and MII VIT), while the other half were used as fresh controls. Afterwards, the eight groups underwent IVF and IVC, and blastocyst development was assessed at D2, D7 and D8. A chi-square test was used to compare embryo development between the groups. Corresponding phospholipid ion intensity was expressed in arbitrary units, and following principal components analyses (PCA) the data were distributed on a 3D graph. Oocytes obtained from superstimulated animals showed a greater rate of developmental (Pvitrification because the blastocyst rate at D7 was similar (P>0.05) for all groups (CONT VIT = 2.8±3.5%, IMA VIT = 2.9±4.0%, FSH VIT = 4.3±7.2% and MII VIT = 3.6±7.2%). MALDI-TOF revealed that oocytes from all maturation groups had similar phospholipid contents, except for 760.6 ([PC (34:1) + H]+), which was more highly expressed in MII compared to FSH (Pbovine oocytes to vitrification.

    Vascular endothelial growth factor (VEGF) has been suggested to play a role in the pathophysiology of polycystic ovary syndrome (PCOS) and may contribute to increased risk of ovarian hyperstimulation syndrome (OHSS) in affected individuals. Vitamin D (VitD) supplementation improves multiple clinical parameters in VitD-deficient women with PCOS and decreases VEGF levels in several other pathologic conditions. Unveiling the basic mechanisms underlying the beneficial effects of vitamin D on PCOS may enhance our understanding of the pathophysiology of this syndrome. It may also suggest a new treatment for PCOS that can improve it through the same mechanism as vitamin D and can be given regardless of vitamin D levels. Therefore, we aimed to explore the effect of VitD supplementation on serum VEGF levels and assess whether changes in VEGF correlate with an improvement in characteristic clinical abnormalities of PCOS. This is a randomized placebo-controlled trial conducted between October 2013 and March 2015. Sixty-eight VitD-deficient women with PCOS were recruited. Women received either 50,000 IU of oral VitD3 or placebo once weekly for 8 weeks. There was a significant decrease in serum VEGF levels (1106.4 ± 36.5 to 965.3 ± 42.7 pg·mL -1 ; p PCOS. This is a novel molecular explanation for the beneficial effects of VitD treatment. It also suggests the need to investigate a potential role of VitD treatment in reducing the incidence or severity of OHSS in VitD-deficient women with PCOS.

    Venom immunotherapy (VIT) is able to protect insect venom-allergic patients against life-threatening sting reactions. Standardized sting challenges can be used as a diagnostic tool to check whether VIT is required. No data are available on the long-term predictive value of sting challenge tests. The purpose of this study was to investigate the long-term predictive value of sequential bee-sting challenges with respect to the ability to predict future sting reactions in bee-venom (BV) allergic children. Between 1988 and 1992, 92 BV-allergic children had been challenged with sequential bee stings at intervals of 2-6 weeks to determine the necessity of VIT. In 1996, all 92 families were followed-up using standardized telephone interviews. Until the follow-up, 61 children (66.3%) had experienced at least one natural bee sting. Based on the results of the initial challenge tests, 13 of the 61 patients had been started on VIT. Two of these 13 (15.4%) developed systemic reactions 1 year after VIT of 5 years, of which one was mild and one was severe. Among the 48 re-stung patients who were not treated with VIT, three children (6.3%) experienced mild systemic reactions, whereas 45 children reported no more than a local reaction. The long-term predictive value of sequential bee-sting challenge tests for systemic reactions in children not treated with VIT remained at a level of 93.8% (95% confidence interval: 82.8-98.7%) even over a period of more than 6 years. Based on this data, we conclude that sequential bee-sting challenges are a powerful tool to determine the necessity for VIT in BV-allergic children.

    Antioxidant defences are comparatively low during foetal development making the brain particularly susceptible to oxidative stress during antioxidant deficiencies. The brain is one of the organs containing the highest concentration of vitamin C (VitC) and VitC deficiency during foetal development may place the brain at risk of redox status imbalance. In the present study, we investigated the developmental pattern and effect of VitC deficiency on antioxidants, vitamin E and superoxide dismutase (SOD), assessed oxidative damage by measuring malondialdehyde (MDA), hydroxynonenal (HNE) and nitrotyrosine (NT) and analysed gene and protein expression of apoptosis marker caspase-3 in the guinea pig foetal brain at two gestational (GD) time points, GD 45/pre-term and GD 56/near term following either a VitC sufficient (CTRL) or deficient (DEF) maternal dietary regime. We show that except for SOD, antioxidants and oxidative damage markers are differentially expressed between the two GDs, with high VitC (p<0.0001), NT modified proteins (p<0.0001) and active caspase-3 levels (p<0.05) at pre-term and high vitamin E levels (p<0.0001), HNE (p<0.0001) and MDA (p<0.0001) at near term. VitC deficiency significantly increased SOD activity (p<0.0001) compared to CTRLs at both GDs indicating a compensatory response, however, low levels of VitC significantly elevated MDA levels (p<0.05) in DEF at near term. Our results show a differential regulation of the investigated markers during late gestation and suggest that immature brains are susceptible to oxidative stress due to prenatal vitC deficiency in spite of an induction of protective adaptation mechanisms.

    Treatment failure during venom immunotherapy (VIT) may be associated with a variety of risk factors. Our aim was to evaluate the association of baseline serum tryptase concentration (BTC) and of other parameters with the frequency of VIT failure during the maintenance phase. In this observational prospective multicenter study, we followed 357 patients with established honey bee or vespid venom allergy after the maintenance dose of VIT had been reached. In all patients, VIT effectiveness was either verified by sting challenge (n = 154) or patient self-reporting of the outcome of a field sting (n = 203). Data were collected on BTC, age, gender, preventive use of anti-allergic drugs (oral antihistamines and/or corticosteroids) right after a field sting, venom dose, antihypertensive medication, type of venom, side effects during VIT, severity of index sting reaction preceding VIT, and duration of VIT. Relative rates were calculated with generalized additive models. 22 patients (6.2%) developed generalized symptoms during sting challenge or after a field sting. A strong association between the frequency of VIT failure and BTC could be excluded. Due to wide confidence bands, however, weaker effects (odds ratios honey bee venom allergy. Preventive use of anti-allergic drugs may be associated with a higher protection rate. It is unlikely that an elevated BTC has a strong negative effect on the rate of treatment failures. The magnitude of the latter, however, may depend on the method of effectiveness assessment. Failure rate is higher in patients suffering from bee venom allergy.

    This paper reports a method for the rapid, sensitive and simultaneous analysis of vitamin D (Vit D) and 25-hydroxyvitamin D (25OH-Vit D) in meats. Samples were saponified and underwent solid phase extraction with analysis by normal phase liquid chromatography (LC) with ion trap mass spectroscopy (IT-MS), using positive polarity atmospheric pressure chemical ionisation (APCI). Limits of detection (LOD) and quantification (LOQ) for Vit D and 25OH-Vit D were 0.03 and 0.05 μg/100g respectively. Deuterium labelled Vit D and 25OH-Vit D internal standards were added as surrogates prior to saponification, correcting for extraction inefficiencies and potential MS matrix enhancement or suppression effects. Recoveries using internal/surrogate standard correction ranged from 80% to 100% for all vitamers. Measurement uncertainty ranged from 6% to 15% for all vitamers in this method. This process required only 7.5 g of sample per extraction and a batch of 28 extractions could be completed in six hours. Crown Copyright © 2012. Published by Elsevier Ltd. All rights reserved.

    Each year in the UK, there are between two and nine deaths from anaphylaxis caused by bee and wasp venom. Anaphylactic reactions can occur rapidly following a sting and can progress to a life-threatening condition within minutes. To avoid further reactions in people with a history of anaphylaxis to bee and wasp venom, the use of desensitisation, through a process known as venom immunotherapy (VIT), has been investigated and is in use in the UK. VIT consists of subcutaneous injections of increasing amounts of purified bee and/or wasp venom extract. Pharmalgen® products (ALK Abelló) have had UK marketing authorisation for VIT (as well as diagnosis) of allergy to bee venom (using Pharmalgen Bee Venom) and wasp venom (using Pharmalgen Wasp Venom) since March 1995. This review assessed the clinical effectiveness and cost-effectiveness of Pharmalgen in providing immunotherapy to individuals with a history of type 1 [immunoglobulin E (IgE)-mediated] systemic allergic reaction to bee and wasp venom. A comprehensive search strategy using a combination of index terms (e.g. Pharmalgen) and free-text words (e.g. allerg$) was developed and used to interrogate the following electronic databases: EMBASE, MEDLINE, The Cochrane Library. Papers were included if they studied venom immunotherapy using Pharmalgen (PhVIT) in patients who had previously experienced a systemic reaction to a bee and/or a wasp sting. Comparators were any alternative treatment options available in the NHS without VIT. Included outcomes were systemic reactions, local reactions, mortality, anxiety related to the possibility of future allergic reactions, health-related quality of life (QoL) and adverse reactions (ARs) to treatment. Cost-effectiveness outcomes included cost per quality-adjusted life-years (QALYs) gained. Because of the small number of published randomised controlled trials (RCTs), no meta-analyses were conducted. A de novo economic model was developed to assess the cost-effectiveness of PhVIT

    Full Text Available Vitamin D (VitD, which is well known for its classic role in the maintenance of bone mineral density, has now become increasingly studied for its extra-skeletal roles. It has an important influence on the body’s immune system and modulates both innate and adaptive immunity and regulates the inflammatory cascade. In this review our aim was to describe how VitD might influence immune responsiveness and its potential modulating role in vaccine immunogenicity. In the first instance, we consider the literature that may provide molecular and genetic support to the idea that VitD status may be related to innate and/or adaptive immune response with a particular focus on vaccine immunogenicity and then discuss observational studies and controlled trials of VitD supplementation conducted in humans. Finally, we conclude with some knowledge gaps surrounding VitD and vaccine response, and that it is still premature to recommend “booster” of VitD at vaccination time to enhance vaccine response.

    To find out toxico-pathological effects of arsenic (As) and ameliorating effect of ascorbic acid (Vit C), broilers birds were administered 50 and 250 mg/kg arsenic and Vit C, respectively alone/in combination. As-treated birds exhibited severe signs of toxicity such as dullness, depression, increased thirst, open mouth breathing and watery diarrhea. All these signs were partially ameliorated with the treatment of Vit C. As-treated birds showed a significant decrease in serum total proteins while serum enzymes, urea and creatinine were significantly increased. Alkaline phosphatase and lactate dehydrogenase completely whereas proteins, aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea and creatinine were partial ameliorated in birds treated with As+Vit C as compared to As-treated and control birds. Pale and hemorrhagic liver and swollen kidneys were observed in As-treated birds. Histopathologically, liver exhibited congestion and cytoplasmic vacuolation while in kidneys, condensation of tubular epithelium nuclei, epithelial necrosis, increased urinary spaces, sloughing of tubules from basement membrane and cast deposition were observed in As-treated birds. Pathological lesions were partially ameliorated with the treatment of Vit C. It can be concluded that arsenic induces biochemical and histopathological alterations in broiler birds; however, these toxic effects can be partially attenuated by Vit C.

    The objective of this trial was to investigate the influences of conjugated linoleic acid (CLA) and vitamin E (Vit. E) and their interactions on fatty acid composition and vitamins in milk (α-tocopherol, retinol and β-carotene) as well as on α-tocopherol in blood of pluriparous cows from week 6 ante partum until week 10 post-partum (p.p.). We assigned 59 pluriparous German Holstein cows to four treatment groups with the treatment factors CLA and Vit. E at two levels in a 2 × 2 factorial design. Milk fatty acid composition and milk vitamins were analysed on lactation days 7 and 28. α-tocopherol in blood serum was analysed on days -42, -7, 1, 7, 14, 28 and 70 relative to parturition. Milk concentration of α-tocopherol was influenced by Vit. E (p E (p E did not have an impact on milk fatty acid composition, it might be possible to increase the antioxidative capacity of the dairy cow without affecting milk properties. Consequently, combined treatment with CLA and Vit. E might elicit synergistic effects on the cow and milk quality by increasing the proportion of CLA in milk fat as well as the excretion of Vit. E and the Vit. E levels in serum. © 2017 Blackwell Verlag GmbH.

    Vitamin D (vitD) is involved in the phosphor-calcium metabolism and bone pathology, but also in inflammatory and infectious processes such as tuberculosis. The present study evaluates the clinical and epidemiological aspects of active tuberculosis cases and latently infected contacts in whom plasma concentrations of vitD were obtained to determine whether the deficiency of vitD is a risk factor to develop active tuberculosis, especially the more severe forms. Observational, retrospective study that included 86 tuberculosis patients and 80 contacts with latent infection in a 2-year period. When comparing active tuberculosis cases with latent infection contacts, deficiency of vitD (vitD levels <10 ng/mL, odds ratio [OR]: 2.02, 95% confidence interval [CI]: 1.04 to 3.93), male sex (OR: 1.9, 95% CI: 0.96 to 3.71) and non-white race (OR: 0.7, 95% CI: 0.34 to 1.42) were factors independently associated with the diagnosis of tuberculosis. Despite the limited number of subjects studied, there was a association between severe deficit of vitD and the presentation of tuberculosis. Copyright © 2013 Elsevier España, S.L.U.

    Populations of East Asian countries have been known to have low calcium intakes and low serum 25(OH)D concentrations, suggesting that Ca and vitamin D (VitD)-deficiencies are commonly observed. These nutritional imbalances may lead to low peak bone mass (PBM). The low PBM seen in Ca/VitD-deficient individuals may lead to osteoporosis, as well as an increased risk of fracture. A survey was conducted in young Japanese women (n = 296, 21.2 ± 2.3 years old) on their Ca/VitD intakes and serum 25(OH)D levels, which demonstrated a significant positive correlation between VitD intake and serum 25(OH)D levels (R (2) = 0.020, P = 0.016), and the proportion with serum 25(OH)D over 20 ng/mL was significantly increased with VitD intake (P = 0.013). Serum 25(OH)D was negatively correlated to serum intact parathyroid hormone (R (2) = 0.053, P D levels at 20 ng/mL or higher was 11.6 μg/day or greater. It was suggested that the recommended VitD intake allowance, defined in the Adequate Intakes as 5.5 μg/day, may not be sufficient to maintain serum 25(OH)D levels for bone health.

  20. Multifaceted remodeling by vitamin C boosts sensitivity of Mycobacterium tuberculosis subpopulations to combination treatment by anti-tubercular drugs

    Full Text Available Bacterial dormancy is a major impediment to the eradication of tuberculosis (TB, because currently used drugs primarily target actively replicating bacteria. Therefore, decoding of the critical survival pathways in dormant tubercle bacilli is a research priority to formulate new approaches for killing these bacteria. Employing a network-based gene expression analysis approach, we demonstrate that redox active vitamin C (vit C triggers a multifaceted and robust adaptation response in Mycobacterium tuberculosis (Mtb involving ~ 67% of the genome. Vit C-adapted bacteria display well-described features of dormancy, including growth stasis and progression to a viable but non-culturable (VBNC state, loss of acid-fastness and reduction in length, dissipation of reductive stress through triglyceride (TAG accumulation, protective response to oxidative stress, and tolerance to first line TB drugs. VBNC bacteria are reactivatable upon removal of vit C and they recover drug susceptibility properties. Vit C synergizes with pyrazinamide, a unique TB drug with sterilizing activity, to kill dormant and replicating bacteria, negating any tolerance to rifampicin and isoniazid in combination treatment in both in-vitro and intracellular infection models. Finally, the vit C multi-stress redox models described here also offer a unique opportunity for concurrent screening of compounds/combinations active against heterogeneous subpopulations of Mtb. These findings suggest a novel strategy of vit C adjunctive therapy by modulating bacterial physiology for enhanced efficacy of combination chemotherapy with existing drugs, and also possible synergies to guide new therapeutic combinations towards accelerating TB treatment.

  1. 1,25-dihydroxyvitamin D3 conditioned CD11c+ dendritic cells are effective initiators of CNS autoimmune disease

    Full Text Available Dendritic cells (DC play a crucial role in regulating T cell activation. Due to their capacity to shape the immune response, tolerogenic DC have been used to treat autoimmune diseases. In this study we examined whether 1,25 dihydroxyvitamin D3 conditioned bone marrow derived DC (VitD-BMDC were able to limit the development of autoimmune pathology in experimental autoimmune encephalomyelitis (EAE. We found that VitD-BMDC had lower expression of MHC class II and co-stimulatory molecules and were less effective at priming autoreactive T cells in-vitro. Using our recently described BMDC driven model of EAE, we demonstrated that VitD-BMDC had a significantly reduced ability to initiate EAE. We found that the impaired ability of VitD-BMDC to initiate EAE was not due to T cell tolerisation. Instead, we discovered that the addition of 1,25(OH2D3 to BMDC cultures resulted in a significant reduction in the proportion of CD11c+ cells. Purified CD11c+VitD-BMDC were significantly less effective at priming T cells in-vitro yet were similarly capable of initiating EAE as vehicle treated CD11c+BMDC. This study demonstrates that in-vitro assays of DC function can be a poor predictor of in-vivo behaviour and that CD11c+VitD-BMDC are highly effective initiators of an autopathogenic T cell response.

    This study was conducted to verify whether vitamin (Vit) E or natural clay as feed additives has the potential to modulate the deleterious effects resulting from exposure to cadmium (Cd) in growing Japanese quail. 648 Japanese quail chicks (1 week old) were used to evaluate the effects of dietary Cd (0, 40, 80 and 120 mg/kg diet) and two levels of Vit E (0, 250 mg/kg diet) or two levels of natural clay (0 and 100 mg/kg diet) to study the influences of Cd, Vit E, clay or their different combinations on growth performance, carcass traits, some blood biochemical components and Cd residues in muscles and liver. Live BW and weight gain of quails were linearly decreased with increasing dietary Cd levels. Moreover, feed conversion was significantly worsened with increasing Cd level. Mortality percentage was linearly increased as dietary Cd level increased up to 120 mg/kg diet. Carcass percentage was linearly decreased as dietary Cd level increased. While, giblets percentage were linearly and quadratically differed as dietary Cd level increased. Cd caused significant changes in total plasma protein, albumin, globulin, A/G ratio, creatinine, urea-N and uric acid concentrations as well as ALT, AST and ALP activities. Increasing dietary Cd level was associated with its increase in the muscles and liver. Dietary supplementation with 250 mg of Vit E/kg diet or 100 mg clay/kg improved live BW, BW gain and feed conversion when compared with the un-supplemented diet. Quails fed diet contained 250 mg Vit E/kg and those fed 100 mg clay/kg had the highest percentages of carcass and dressing than those fed the un-supplemented diet. Blood plasma biochemical components studied were better when birds received 250 mg of Vit E/kg diet and those received 100 mg clay/kg. Cd residues in the muscles and liver were significantly less in the birds had 250 mg of Vit E/kg or those received 100 mg clay/kg diet than those un-supplemented with Vit E.

    Omega-3 (omega-3) fatty acid rich-fish oil (FO) and vitamin E (vit-E) may delay the progress of certain autoimmune diseases. The present study examined the mechanism of action of omega-3 and omega-6 lipids and vit-E on the serum cytokines and lipid mediators in autoimmune-prone MRL/lpr mice (a model for rheumatoid arthritis, RA). The lpr (lymphoproliferative) gene is overexpressed in these mice causing extensive lymphoproliferation, lupus-like symptoms and accelerated aging. Weanling female MRL/lpr and congenic control MRL/++ mice were fed 10% corn oil (CO, omega6) or FO-based semipurified diets containing two levels of vitamin E (vit-E-75, I.U. and vit-E-500 I.U./Kg diet) for four months. At the end of the experiment, serum anti-DNA antibodies, cytokines and lipid mediators levels were determined. The appearance of enlarged lymph nodes was delayed in the mice fed FO, and the FO-500 IU vit-E diet offered further protection against enlargement of lymph nodes. The MRL/lpr mice exhibited significantly higher levels of serum anti-dsDNA antibodies. The FO-fed mice had significantly lower serum IL-6, IL-10, IL-12, TNF-alpha, PGE2, TXB2 and LTB4 levels compared with CO-fed mice. In mice fed 500 IU vit-E diets, the serum IL-6, IL-10, IL-12 and TNF-alpha levels were significantly lower and serum IL-1beta was significantly higher compared to 75 IU-vit-E-fed mice in CO/FO or both. The levels of anti-DNA antibodies, IL-4, IL-6, TNF-alpha, IL-10 and IL-12 were higher in the sera of MRL/lpr mice. The FO diet lowered the levels of these cytokines (except IL-4) and lipid mediators. Adding 500 IU of vit-E to the FO diet further lowered the levels of IL-6, IL-10, IL-12, and TNF-alpha. It is clear from our observations that the beneficial effects of FO can be enhanced by the addition of 500 IU of vit-E in the diet. The FO diet containing 500 IU of vit-E may specifically modulate the levels of IL-6, IL-10, IL-12 and TNF-alpha and thereby may delay the onset of autoimmunity in the MRL

    Honey bee (Apis mellifera) gene expression related to immunity for hymenoptaecin (AmHym) and defensin-1 (AmDef-1), longevity for vitellogenin (AmVit2) and stem cell proliferation for poly U binding factor 68 kDa (AmPuf68) was compared following Varroa destructor parasitism, buffer injection and injection of V. destructor compounds in its homogenate. In adults, V. destructor parasitism decreased expression of all four genes, while buffer injection decreased expression of AmHym, AmPuf68 and AmVit2, and homogenate injection decreased expression of AmPuf68 and AmVit2 but increased expression of AmDef-1 relative to their respective controls. The effect of V. destructor parasitism in adults relative to the controls was not significantly different from buffer injection for AmHym and AmVit2 expression, and it was not significantly different from homogenate injection for AmPuf68 and AmVit2. In brood, V. destructor parasitism, buffer injection and homogenate injection decreased AmVit2 expression, whereas AmHym expression was decreased by V. destructor parasitism but increased by buffer and homogenate injection relative to the controls. The effect of varroa parasitism in brood was not significantly different from buffer or homogenate injection for AmPuf68 and AmVit2. Expression levels of the four genes did not correlate with detectable viral levels in either brood or adults. The results of this study indicate that the relative effects of V. destructor parasitism on honey bee gene expression are also shared with other types of stresses. Therefore, some of the effects of V. destructor on honey bees may be mostly due to wounding and injection of foreign compounds into the hemolymph of the bee during parasitism. Although both brood and adults are naturally parasitized by V. destructor, their gene expression responded differently, probably the result of different mechanisms of host responses during development.

    Full Text Available Background: Recurrent aphthous stomatitis (RAS is a chronic inflammatory disease of the oral cavity. Although many factors have been suggested as possible causes of RAS, its precise etiology is controversial. Vitamin B12 (vit B12 and iron deficiencies may cause RAS. Aims: We investigated the level of serum hemoglobin (Hb and vit B12 in patients with RAS and to compare them with healthy controls. Materials and Methods: This was a prospective, cross-sectional study. Patients who had had at least one episode of oral ulcerations per month since childhood were diagnosed as having RAS. Blood samples were drawn from the RAS group and control group for measuring blood Hb and vit B12 concentrations. Results: Exactly 195 patients (62 men and 133 women with RAS and 217 healthy controls (62 men and 155 women were enrolled in the study. The RAS group had significantly lower mean Hb levels than the control group (P < 0.001. No significant difference in the mean vit B12 level was demonstrated between the study group and controls. Around 58 (29.7% patients were diagnosed as Hb deficient in the RAS group and 21 (9.7% patients in controls. Vit B12 deficiency was diagnosed in 63 (32.3% individuals in the RAS group and 32 (14.7% individuals among controls. Conclusions: In our study, vit B12 and Hb deficiency were found higher in patients with RAS compared to the control group. Therefore, we suggested the investigation of the level of vit B12 and Hb in patients with RAS.

    Oxidative stress and a disrupted antioxidant system are involved in a variety of pregnancy complications. In the present study, the role of vitamin E (Vit E) and folate as radical scavengers on the GSH homeostasis in stress oxidative induced in rat endometrial cells was investigated. Primary endometrial stromal cell cultures treated with 50 and 200 µM of H2O2 and evaluated the cytoprotective effects of Vit E (5 µM) and folate (0.01 µM) in H2O2-treated cells for 24 h. Following the exposure of endometrial cells to H2O2 alone and in the presence of Vit E and/or folate, cell survival, glutathione peroxidase (GPx) and glutathione reductase activities and the level of reduced glutathione (GSH) were measured. Cell adhesions comprise of cell attachment and spreading on collagen were determined. Flow cytometric analysis using annexin V was used to measure apoptosis. H2O2 treatment showed a marked decrease in cell viability, GPx and GR activities and the level of GSH. Although Vit E or folate had some protective effect, combination therapy with Vit E and folate attenuated all the changes due to H2O2 toxicity. An increasing number of alive cells was showed in the cells exposed to H2O2 (50 µM) accompanied by co-treatment with Vit E and folic acid. The present findings indicate that co-administration of Vit E and folate before and during pregnancy may maintain a viable pregnancy and contribute to its clinical efficacy for the treatment of some idiopathic infertility.

    To determine the knowledge and management of vitamin D (Vit D) in primary care (PC). Observational study. A total of 69 primary care centres, with 57 in Barcelona and 12 in Huesca. All medical and nursing graduates of these centres. A specifically designed questionnaire was used to collect knowledge on the actions of Vit D (on bone metabolism, cardiovascular and immune systems), its deficiency and prevention measures. Of the total of 2100 professionals, 785 completed the survey (37.78%), of whom 79.9% were women. Their mean age was 47 years (SD: 9.7). Only 4.8% knew the overall actions of Vitamin D, although the majority (66%) knew only its effects on bone metabolism. Almost two-thirds (62.4%) were unaware that its deficiency was a common problem, and 54.9% believed that photoprotection was contraindicated. Almost three-quarters of those surveyed (73.6%) never or almost never determined Vit D levels in their patients. A minority (23%) offered advice to maintain an adequate level of Vit D, with the most frequent being sun exposure (16.8%). Pediatricians were more knowledgeable (p<.001) and offered more advice for maintaining adequate levels of Vit D in blood (p<.001). Most of the professionals were unaware of the overall actions of Vit D, or that its deficiency was common, or the factors contributing to this. The advice that was more often offered to avoid its deficiency was not the safest. Paediatricians are more aware of how to prevent Vit D deficiency.

    To determine the relationship between a measure of fatigue and 2 indices of physical fitness, lower limb extensor power (LLEP) and walking economy. This was a cross-sectional study of patients with stroke. Fatigue was assessed by vitality (VIT) score of the Medical Outcomes Study 36-Item Short-Form Health Survey version 2 (SF-36v2). LLEP of the unaffected limb was measured using a lower leg extensor power rig. Walking economy was calculated by measuring oxygen consumption (mL·kg(-1)·m(-1)) during walking at a comfortable speed. Bivariate analyses were performed relating VIT to indices of fitness. Multiple regression analyses were also performed and included age, sex, and either SF-36v2 emotional role function or SF-36v2 mental health, as predictors of VIT. Community setting. Participants (N=66; 36 men; mean age ± SD, 71.0±9.9y) were all community dwelling, had survived a stroke, were able to walk independently, and had completed their stroke rehabilitation. Not applicable The main outcome measure is SF-36v2 (VIT), with walking economy and LLEP of the limb unaffected by the stroke being independent variables. Walking economy was not significantly related to VIT (R=-.024, P=.86, n=60). LLEP was positively related to VIT in bivariate analysis (R=.38, P=.003, n=58). After controlling for age, sex, and SF-36 emotional role function (or SF-36v2 mental health if the extreme outlier was excluded), LLEP remained a significant predictor of VIT. We found an association between fatigue and reduced LLEP. If a larger study confirms these findings, it would support the need to develop and test interventions to increase LLEP as a treatment for fatigue after stroke.

    In this study, we investigated the protection effect of Vitamin E (Vit E) on formaldehyde (FA) exposure during pregnancy induced apoptosis of cardiomyocytes, and used an HL-1 cell line to confirmed the findings in vivo.Pregnant mice received different doses of FA (0.5 mg/kg, 1.0 mg/kg, 1.5 mg/kg, 0.1 μg Vit E, or 1.5 mg/kg + 0.1 μg Vit E). TUNEL staining was used to reveal the apoptosis in cardiomyocytes, and SOD, MDA, GSH, Livin, and Caspase-3 in cardiomyocytes were detected by ELISA, RT-PCR, and Western blot. For in vitro study, HL-1 cells were treated with vehicle, 5 μmol/L FA, 25 μmol/L FA, 50 μmol/L FA, 10 mg/L Vit. E, and 50 μmol/L FA+ 10 mg/L Vit E, respectively. CCK-8 assay and flow cytometry were used to evaluate cell vitality and apoptosis. A high dose of FA exposure led to cytotoxicity in both pregnant mice and offspring, as TUNEL staining revealed a significant apoptosis of cardiomyocytes, and the alternation in SOD, GSH, MDA, Livin, and Caspase-3 was found in cardiomyocytes. 0.1 μg Vit. E could reverse high doses of FA exposure induced apoptosis of cardiomyocytes in both pregnant mice and offspring. The in vitro study revealed that FA exposure induced a decrease of cell viability and increased cell apoptosis, as well as oxidative stress in HL-1 cells with alternation in SOD, GSH, MDA, Livin, and Caspase-3.This study revealed a high dose of FA induced oxidative stress and apoptosis of cardiomyocytes in both pregnant mice and offspring, and Vit E supplement during pregnancy reversed the systemic and myocardial toxicity of FA.

    The association of dietary vitamin C (vit C) on periodontitis requires more valid evidence from large representative samples to enable sufficient adjustments. This study aimed to evaluate the association between dietary vit C intake and periodontitis after controlling for various confounders in the representative Korean adult population. A total of 10,930 Korean adults (≥19 years) from the fourth Korean National Health and Nutrition Examination Survey data set were included in this cross-sectional study. Periodontitis was defined as community periodontal index score of 3 or 4. Dietary vit C intake was estimated from a 24-hour dietary record, and categorized into adequate and inadequate according to the Korean Estimated Average Requirement value. Potential confounders included age, sex, income, frequency of tooth brushing, use of floss, dental visit, drinking, smoking, diabetes, hypercholesterolemia, hypertension, and obesity. A multivariable logistic regression analysis and stratified analysis were applied. Those with inadequate dietary vit C intake were more likely by 1.16 times to have periodontitis than those with adequate dietary vit C intake (adjusted odds ratio [aOR] = 1.16, 95% confidence interval = 1.04-1.29). Lowest and middle-low quartile of dietary vit C intake, compared to highest quartile of dietary vit C intake, showed significant association (aOR = 1.28 and 1.22 respectively), which was in a biological-gradient relationship (trend-p periodontitis among Korean adults. Hence, adequate intake of dietary vitamin C could be substantially important on the promotion of periodontal health among Korean adults.

    Valproic acid (VPA, 2-propyl pentanoic acid) is a broad-spectrum antiepileptic drug (AED) and is commonly used in the treatment of bipolar disorders and epilepsy. AEDs are known to result in vascular disturbances. Vitamin B6 (Vit B6) is water soluble vitamin essential for normal growth, development, and metabolism. In this study, we aimed to investigate the protective effects of Vit B6 against VPA-induced lens damage in experimental animals. In this study, male 4-month-old, Sprague-Dawley rats were used. The animals were divided into four groups. Group I was intact control animals. Group II rats were administered with Vit B6 (50 mg/kg/day) for 7 days. Group III rats were administered with only VPA (500 mg/kg/day) for 7 days. Group IV was given VPA + Vit B6 (in a same dose and time). Vit B6 was given to rats by gavage and VPA was given by intraperitoneally. On the 8th day of experiment, all of the animals were fasted overnight and then killed under ether anesthesia. Lens tissues were taken from animals, homogenized in 0.9% saline to make up a 10% homogenate. The homogenates was used for glutathione (GSH), lipid peroxidation (LPO), protein levels, and enzyme analysis. In VPA groups, levels of lens GSH and LPO and activities of glutathione-S-transferase, glutathione peroxidase, glutathione reductase, and aldose reductase were increased, while superoxide dismutase activity was decreased. Treatment with Vit B6 reversed these effects. These results demonstrated that administration of Vit B6 is potentially beneficial agent to reduce the lens damage in VPA toxicity, probably by decreasing oxidative stress. © The Author(s) 2014.

  17. Does Vitamin C Deficiency Promote Fatty Liver Disease Development?

    2014-12-01

    Full Text Available Obesity and the subsequent reprogramming of the white adipose tissue are linked to human disease-complexes including metabolic syndrome and concurrent non-alcoholic fatty liver disease (NAFLD and non-alcoholic steatohepatitis (NASH. The dietary imposed dyslipidemia promotes redox imbalance by the generation of excess levels of reactive oxygen species and induces adipocyte dysfunction and reprogramming, leading to a low grade systemic inflammation and ectopic lipid deposition, e.g., in the liver, hereby promoting a vicious circle in which dietary factors initiate a metabolic change that further exacerbates the negative consequences of an adverse life-style. Large epidemiological studies and findings from controlled in vivo animal studies have provided evidence supporting an association between poor vitamin C (VitC status and propagation of life-style associated diseases. In addition, overweight per se has been shown to result in reduced plasma VitC, and the distribution of body fat in obesity has been shown to have an inverse relationship with VitC plasma levels. Recently, a number of epidemiological studies have indicated a VitC intake below the recommended daily allowance (RDA in NAFLD-patients, suggesting an association between dietary habits, disease and VitC deficiency. In the general population, VitC deficiency (defined as a plasma concentration below 23 μM affects around 10% of adults, however, this prevalence is increased by an adverse life-style, deficiency potentially playing a broader role in disease progression in specific subgroups. This review discusses the currently available data from human surveys and experimental models in search of a putative role of VitC deficiency in the development of NAFLD and NASH.

    This study aimed to investigate the effects of dietary emodin, high-dose vitamin E and their combination on the growth of Megalobrama amblycephala and its resistance to acute crowding stress. The fish were randomly divided into four groups: a control group fed with basal diet, and three treatment groups fed with basal diet supplemented with 60 mg/kg emodin (the emodin group), 500 mg/kg vitamin E (the vit E group), and 60 mg/kg emodin together with 500 mg/kg vitamin E (the combination group). After 60 days, the fish were exposed to acute crowding stress for 24 h. The results showed that the weight gain of the vit E group, specific growth rate of the vit E group, total serum protein concentration (TP) of the vit E group, serum lysozyme activity of the emodin group, serum superoxide dismutase (SOD) activity of the emodin group, hepatic heat shock protein 70 (HSP70) levels of the vit E group and the emodin group, and serum alanine aminotransferase (ALT) activity of the combination group significantly increased while the weight gain and specific growth rate of the combination group significantly decreased compared with the control group before stress. After crowding stress, the vit E group had improved serum TP 12 h post-stress, hepatic SOD activity 24 h post-stress, and hepatic HSP70 mRNA levels 12 and 24 h post-stress while the emodin group had enhanced serum SOD activity 12 and 24 h post-stress and hepatic HSP70 mRNA levels 12 and 24 h post-stress, as compared with the control. However, the serum cortisol content of the three treatment groups 12 and 24 h post-stress, ALT activity in the vit E group and emodin group 24 h post-stress, and serum alkaline phosphatase and liver catalase activity in the combination group 24 h post-stress were lower than those in the control group. The cumulative mortality was lower in the emodin, vit E, and combination group after Aeromonas hydrophila infection compared with the control group. Therefore, dietary supplementation with 60 mg

    The aim of this study was to evaluate the effect of dietary supplementation of vitamin K (vit K) and Ca in the diets of laying hens on bone and blood parameters and performance during the growing phase and the effects on the laying phase up to 32 weeks. The study utilized 120 Hy-Line W-36 pullets in the growing phase (13-18 weeks), 80 laying hens in the production phase (20-32 weeks), distributed in a completely randomized design in a 2 × 5 factorial arrangement, two levels of Ca (0.8 and 1.4%) and five levels of vit K supplementation (0, 2, 8, 16 and 32 mg/kg) with four experimental units. An experimental diet was fed during the growing phase, and the commercial diet was fed during the production phase and were analysed for biochemistry and bone variables at 18 and 32 weeks. In pullets, a significant interaction of levels of vit K and Ca was observed for total serum calcium (mg/dl), Seedor index, Ca in the bones (%) and medullary bone (%). Pullets at 18 weeks of age, receiving diets with 1.4% Ca, displayed a quadratic effect of vit K with better results for these variables with 17.86, 14.59, 14.48 and 16.80 mg/kg of vit K, respectively. For level 0.8% Ca no effect of vit K was observed. The treatments during the growing phase had no effect on egg production, performance and biochemistry serum until 32 weeks. Medullary bone (%), there was a significant interaction for 1.4% Ca and a quadratic effect for vit K, with greater medullary bone areas observed with 6.09 mg/kg vit K in the diet. Supplementation with vit K in a diet with 1.4% Ca during the growing phase allowed for an increase in the area of medullary bone at 18 weeks, which was maintained until 32 weeks.

    Increase in oxidative/nitrosative stress is one of the mechanisms associated with the development of cardiotoxicity due to doxorubicin (Dox), a potent chemotherapy drug. Previously, we reported mitigation of Dox-induced oxidative/nitrosative stress and apoptosis by vitamin C (Vit C) in isolated cardiomyocytes. In the present in vivo study in rats, we investigated the effect of prophylactic treatment with Vit C on Dox-induced apoptosis, inflammation, oxidative/nitrosative stress, cardiac dysfunction, and Vit C transporter proteins. Dox (cumulative dose: 15 mg/kg) in rats reduced systolic and diastolic cardiac function and caused structural damage. These changes were associated with a myocardial increase in reactive oxygen species, reduction in antioxidant enzyme activities, increased expression of apoptotic proteins, and inflammation. Dox also caused an increase in the expression of proapoptotic proteins Bax, Bnip-3, Bak, and caspase-3. An increase in oxidative/nitrosative stress attributable to Dox was indicated by an increase in superoxide, protein carbonyl formation, lipid peroxidation, nitric oxide (NO), NO synthase (NOS) activity, protein nitrosylation, and inducible NOS protein expression. Dox increased the levels of cardiac proinflammatory cytokines TNF-α, IL-1β, and IL-6, whereas the expression of Vit C transporter proteins (sodium-ascorbate cotransporter 2 and glucose transporter 4) was reduced. Prophylactic and concurrent treatment with Vit C prevented all these changes and improved survival in the Vit C + Dox group. Vit C also improved Dox-mediated systolic and diastolic dysfunctions and structural damage. These results suggest a cardioprotective role of Vit C in Dox-induced cardiomyopathy by reducing oxidative/nitrosative stress, inflammation, and apoptosis, as well as improving Vit C transporter proteins.NEW & NOTEWORTHY This in vivo study provides novel data that vitamin C improves cardiac structure and function in doxorubicin-induced cardiomyopathy

    Full Text Available Background Serum vitamin D (VitD status is associated with active tuberculosis (TB and TB infection conversion (TBIC. Objectives The objective of the present study was to quantify the risks of TB (latent, conversion, disease in accordance with VitD status and other variables among the contacts of pulmonary TB patients. Methods From 2009 to 2012, a cohort of the contacts of pulmonary TB patients was studied to rule out and prevent TB in Castellon (Spain. The exams performed included a tuberculin skin test (TST, a QuantiFERON Gold in-tube test® (QFTGIT, blood and radiographic tests, and an initial measurement of serum VitD status. Contacts who were initially without active TB were followed up through 2015. Multinomial logistic regression (MLR analyses were carried out. Results From a total of 572 contacts of pulmonary TB patients with VitD status measurement, 523 completed the follow-up (participation rate 91.4%. Among them, five groups could be established: 3 new cases of pulmonary TB (0.6%, 27 cases of TBIC (5.2%, 116 cases of latent TB infection (LTBI (22.2%, 125 uninfected TB contacts with only one TST or QFTGIT measurement (23.9%, and 252 uninfected TB contacts with two TST or QFTGIT measurements (48.2%. The comparison of these five groups revealed several significant differences, including age, whether they were foreign-born, place of residence, social class, high exposure to an index case with sputum acid-fast bacilli (AFB, and VitD status. The MLR analysis for all groups, with the group of uninfected TB contacts with two TST or QFTGIT measurements as a reference, estimated that only two of these factors were significantly associated with TB in three or more groups; these factors were VitD status and high exposure and a sputum AFB-positive index case. VitD status was a protector against pulmonary TB with a relative risk (RR of 0.86 (95% confidence interval [CI] 0.74 - 0.99 and against TBIC (R = 0.95; 95% CI 0.91 - 0.99, while it was not

    Full Text Available Development of new tuberculosis (TB drugs and alternative treatment strategies are urgently required to control the global spread of TB. Previous results have shown that vitamin D3 (vitD3 and 4-phenyl butyrate (PBA are potent inducers of the host defense peptide LL-37 that possess anti-mycobacterial effects.To examine if oral adjunctive therapy with 5,000IU vitD3 or 2x500 mg PBA or PBA+vitD3 to standard chemotherapy would lead to enhanced recovery in sputum smear-positive pulmonary TB patients.Adult TB patients (n = 288 were enrolled in a randomized, double-blind, placebo-controlled trial conducted in Bangladesh. Primary endpoints included proportions of patients with a negative sputum culture at week 4 and reduction in clinical symptoms at week 8. Clinical assessments and sputum smear microscopy were performed weekly up to week 4, fortnightly up to week 12 and at week 24; TB culture was performed at week 0, 4 and 8; concentrations of LL-37 in cells, 25-hydroxyvitamin D3 (25(OHD3 in plasma and ex vivo bactericidal function of monocyte-derived macrophages (MDM were determined at week 0, 4, 8, 12 and additionally at week 24 for plasma 25(OHD3.At week 4, 71% (46/65 of the patients in the PBA+vitD3-group (p = 0.001 and 61.3% (38/62 in the vitD3-group (p = 0.032 were culture negative compared to 42.2% (27/64 in the placebo-group. The odds of sputum culture being negative at week 4 was 3.42 times higher in the PBA+vitD3-group (p = 0.001 and 2.2 times higher in vitD3-group (p = 0.032 compared to placebo. The concentration of LL-37 in MDM was significantly higher in the PBA-group compared to placebo at week 12 (p = 0.034. Decline in intracellular Mtb growth in MDM was earlier in the PBA-group compared to placebo (log rank 11.38, p = 0.01.Adjunct therapy with PBA+vitD3 or vitD3 or PBA to standard short-course therapy demonstrated beneficial effects towards clinical recovery and holds potential for host-directed-therapy in the treatment of TB

    The aim of the study was to evaluate vitamin A (Vit A) plasma levels in children with newly diagnosed neoplasia (NDN) admitted to the Department of Hematology-Oncology of G. Gaslini Institute. Vit A levels, retinol-binding protein (RBP), and nutritional status were evaluated in 54 children with NDN (22 solid tumors other than neuroblastoma, 16 neuroblastomas, 9 lymphomas, 7 acute lymphoblastic leukemia). Biochemical test results were also compared with those of 47 healthy controls (HC) comparable for sex and age. In children with NDN, mean Vit A plasma level results were 350 micrograms/L (95% CI 288-412); in HC they were 517 micrograms/L (95% CI 471-563), P < 0.001. Mean RBP value results were 3.2 mg/dL (95% CI 2.6-3.9) in NDN and 4.9 mg/dL in HC (95% CI 4.5-5.3), P < 0.001. Fifteen (28%) out of 54 children with NDN were classified as well-nourished, 27/54 (50%) were considered at risk of malnutrition, and 12 (22%) were malnourished. Children with NDN presented reduced Vit A and RBP mean values compared with those of HC. Further studies are needed to better evaluate Vit A metabolism in children with cancer at onset.

    Vitamin C (Vit C) is considered to be a vital antioxidant molecule in the brain. Intracellular Vit C helps maintain integrity and function of several processes in the central nervous system (CNS), including neuronal maturation and differentiation, myelin formation, synthesis of catecholamine, modulation of neurotransmission and antioxidant protection. The importance of Vit C for CNS function has been proven by the fact that targeted deletion of the sodium-vitamin C co-transporter in mice results in widespread cerebral hemorrhage and death on post-natal day one. Since neurological diseases are characterized by increased free radical generation and the highest concentrations of Vit C in the body are found in the brain and neuroendocrine tissues, it is suggested that Vit C may change the course of neurological diseases and display potential therapeutic roles. The aim of this review is to update the current state of knowledge of the role of vitamin C on neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis and amyotrophic sclerosis, as well as psychiatric disorders including depression, anxiety and schizophrenia. The particular attention is attributed to understanding of the mechanisms underlying possible therapeutic properties of ascorbic acid in the presented disorders.

    Specific allergen immunotherapy to Hymenoptera venom (VIT) is a basic treatment for patients allergic to Hymenoptera venom. The aim of the study was to evaluate the safety of an ultra-rush regimen compared with the rush and conventional protocols. In 31 patients with an allergy to bee venom and 82 with an allergy to wasp venom, the allergic adverse reactions during VIT were monitored. Patients were selected based on the criteria established by EAACI (European Academy of Allergy and Clinical Immunology) recommendations. Adverse reactions during the ultra-rush immunotherapy were measured, documented and classified according to the criteria of Mueller. Ultra-rush, rush or conventional protocols of the initial phase VIT using the Venomenhal vaccine (Hal Allergy, Leiden, Netherlands) were conducted. Six (13.7%) patients on the ultra-rush regimen, 5 (14.3%) patients on the rush regimen and 9 (26.5%) on conventional VIT experienced an allergic reaction. There were no associations between the adverse allergic reactions and the following factors: gender, total IgE and allergen-specific IgE to wasp or bee venom before the VIT and cardiological drugs that were used. We found that the ultra-rush protocol (similar to the rush protocol) using the Venomenhal vaccine is safer than the conventional protocol.

    Vitamin D (vitD) levels are positively associated with bone health and seasonality affects serum vit D. The aim of the study was to investigate the degree of seasonal variation on 25-hydroxyvitamin D (25(OH)D) serum levels in a population-based cohort of post-menopausal women with osteoporosis. Serum levels of 25(OH)D were assessed in 596 patients (mean age=65.3 years; standard deviation (SD)=9.4) in different time points over a period of 2.5 years. The minimum 25(OH)D serum levels were observed in March (13.4±9.5 ng/ml) and the maximum levels in August, September and October (29.1±16.1, 28.9±12 and 28.4±8.9 ng/ml, respectively). The prevalence of vitD deficiency, insufficiency and sufficiency in March was 76.5, 15.7 and 7.8%, respectively. On the contrary, the highest prevalence of vitD sufficiency was observed in August, September and October (38.1%, 45.3% and 46.5%, respectively). Seasonal variations should be considered when measuring for 25(OH)D serum levels and treating vitD deficiency. Copyright © 2015 International Institute of Anticancer Research (Dr. John G.

    Long-term administration of valproic acid (VPA) is known to promote reproductive impairment mediated by increase in testicular oxidative stress. Vitamin E (VitE) is a lipophilic antioxidant known to be essential for mammalian spermatogenesis. However, the capacity of this vitamin to abrogate the VPA-mediated oxidative stress has not yet been assessed. In the current study, we evaluated the protective effect of VitE on functional abnormalities related to VPA-induced oxidative stress in the male reproductive system. VPA (400 mg kg(-1)) was administered by gavage and VitE (50 mg kg(-1)) intraperitoneally to male Wistar rats for 28 days. Analysis of spermatozoa from the cauda epididymides was performed. The testes and epididymides were collected for measurement of oxidative stress biomarkers. Treatment with VPA induced a decrease in sperm motility accompanied by an increase in oxidative damage to lipids and proteins, depletion of reduced glutathione and a decrease in total reactive antioxidant potential on testes and epididymides. Co-administration of VitE restored the antioxidant potential and prevented oxidative damage on testes and epididymides, restoring sperm motility. Thus, VitE protects the reproductive system from the VPA-induced damage, suggesting that it may be a useful compound to minimize the reproductive impairment in patients requiring long-term treatment with VPA.

    Full Text Available Vitamin D is important for normal development and maintenance of the skeleton. Hypovitaminosis D adversely affects calcium metabolism, osteoblastic activity, matrix ossification, bone remodeling and bone density. It is well known that Vit. D deficiency in the developing skeleton is related to rickets, while in adults is related to osteomalacia. The causes of rickets include conditions that lead to hypocalcemia and/or hypophosphatemia, either isolated or secondary to vitamin D deficiency. In osteomalacia, Vit. D deficiency leads to impairment of the mineralisation phase of bone remodeling and thus an increasing amount of the skeleton being replaced by unmineralized osteoid. The relationship between Vit. D and bone mineral density and osteoporosis are still controversial while new evidence suggests that Vit. D may play a role in other bone conditions such as osteoarthritis and stress fractures. In order to maintain a “good bone health” guidelines concerning the recommended dietary intakes should be followed and screening for Vit. D deficiency in individuals at risk for deficiency is required, followed by the appropriate action.

    Full Text Available Thirty-two adult riverine buffaloes (Buhalis bubalus in their last trimester of pregnancy were selected and randomly divided into four groups. The buffaloes of group I served as control. Animals in group II, III and IV were treated twice (7 days apart with levamisole hydrochloride (0.5mg/kg b. w. orally, Etosol (Vit E+Se, 10ml, I/m and Bacilli Calmette Guerine (BCG (0.5 ml/animal, s/c, respectively. Blood samples were collected at weekly intervals starting day 0 untill parturition. Total erythrocytic count and packed cell volume values were higher (P<0.05 in levamisole and vit E+Se treated group of buffaloes. Haemoglobin concentration was higher (P<0.05 inVit E+Se treated group. MCV, MCH and MCHC remained unchanged among all the experimental groups. Total leukocyte count was higher (P<0.05 in levamisole treated group of buffaloes. Differential leukocyte counts (relative revealed moderate lymphocytosis in all immunomodulated groups with significantly higher counts in Vit E+Se treated buffaloes. It was inferred that levamisole and vit E-se altered some haematological values, whereas BCG did not affect the haematological parameters.

    2006-12-01

    Full Text Available Plasma α-tocopherol (vit E and blood selenium (Se concentrations in February were determined in samples from 314 dairy cows in Norway, selected to provide a representative subset of the Norwegian dairy cow population. Each sample was followed by a questionnaire with information about feeding of the cow at the time of sampling. The results were correlated to herd data and to calving and health data for each cow from the Norwegian Dairy Herd Recording System and the Norwegian Cattle Health Recording System. The mean concentrations were 6.9 μg vit E per ml plasma and 0.16 μg Se per g blood. Both levels were highest in mid lactation. Plasma vit E varied with the amount of silage fed to the cow, while blood Se varied with the amount of concentrates and mineral supplements, and with geographical region. No differences in vit E or Se levels were found between cows with recorded treatments for mastitis, parturient paresis or reproductive disorders in the lactation during or immediately prior to sampling, and those without such treatments. For ketosis, a small difference in blood Se was found between the groups with or without recorded treatments. It is concluded that winter-fed lactating cows in Norway had an adequate plasma level of vit E and a marginal-to-adequate level of Se.

    Full Text Available This study was conducted to observe the arsenic (As toxicity lesions in birds and to know either Vit C ameliorates these toxic effects or not. One-day-old broilers chicks (n=72 procured from a local hatchery were randomly divided into four equal groups. First group was kept as control and second group was given As (50 mg/kg BW via crop tubing. Third group received in addition to As, Vit C (250 mg/kg BW whereas fourth group received only Vit C. Killing by neck dislocation of randomly selected six birds from each group was carried out on experimental days 0, 16 and 32 for collection of blood and tissues specimens. Arsenic treated birds showed clinical signs of toxicity throughout the experiment than all other groups. These clinical signs included decreased body weight and feed intake, dullness, open mouth breathing, increased thirst, ruffled feathers, pale comb, skin irritation and watery diarrhea which were not significant in any other group. As treated group showed a significant (P<0.05 decrease in hematological parameters. Severe gross and histopathological changes were observed in intestines, spleen and lungs of birds fed with As than all other groups. Decreased height of villi of middle portion of small intestines was also observed in As treated birds. Villi height in Vit C treated group increased as compared to control group. It was concluded that As induces severe toxic effects in broiler birds; however, these toxic effects can be partially ameliorated by Vit C.

    Full Text Available Background: Hyperbilirubinemia is a common and benign problem in neonates worldwide. It is observed during the 1st week of life in approximately 60% of term neonates and 80% of preterm neonates. Phototherapy is most widely used as therapy for unconjugated hyperbilirubinemia. Phototherapy is related to oxidative stress and lipid peroxidation. The present study is undertaken to establish the relation between anti-oxidant status and the marker of lipid peroxidation in neonatal hyperbilirubinemia before and after phototherapy. Objectives: To estimate the levels of MDA (malondialdehyde and vit-E levels in neonatal hyperbilirubinemia before and after phototherapy. Material and Methods: A total of 30 patients were eligible for the study who met the inclusion and exclusion criteria. Blood sample was collected from neonates of preterm/full term age 1 to 10 days with hyperbilirubinemia undergoing phototherapy. Total Bilirubin, Direct Bilirubin, MDA and vit-E levels were estimated in serum by thiobarbituric acid (TBA method and Backer and Frank’s Method respectively. Results: The present study showed increase in Total bilirubin, Direct bilirubin, MDA and decrease in vit-E levels before phototherapy when compared to control group and same subjects after phototherapy showed decrease in Total bilirubin and Direct bilirubin, MDA and a further decrease in vit-E levels. Conclusion: From these results it is concluded though phototherapy had a beneficial effect in treatment of neonatal hyperbilirubinemia, supplementation of vit-E is necessary in addition to phototherapy.

    Effects produced by different doses of Vit C (2, 3 and 4 gr/day) on lipoprotein and hepatic lipase activities were studied between a group of 35 ambulatory patients, men and women, affected by diabetes mellitus type II with macroangiopathy at lower limbs and/or food. The medium age of patients was 62 years, ranging from 44 to 82 years. Patients were aleatory divided into four groups. One from those four groups was treated with placebo, the other three received Vit C. In the group treated with 3 gr./day of Vit C we found a significant reduction and increase (p less than 0.05) of lipoprotein and hepatic lipase activities, respectively, when we compared outcomes before and after eight weeks of treatment with Vit C. By other hand, when we compared the different groups, we found a significant increase in the hepatic lipase activity in the same group, particularly between the patients whose plasmatic Vit C levels before treatment were reduced. We didn't found any significant change in the rest of parameters.

    To determine whether treatment with combined pentoxifylline (PTX) and tocopherol (Vit.E) can improve uterine parameters in hormonal replacement therapy (HRT)-resistant women with premature ovarian failure (POF), for whom the outcome of assisted reproductive technology is usually negative. We previously reported that uterine radiation-induced fibrosis is reversible by combined PTX-Vit.E treatment. Case report. Volunteer participants in an oocyte donation (OD) program in a French public hospital. Three women with POF (ages 36 +/- 2 years) using HRT exhibited uterine hormonoresistance, although they had high E(2) plasma levels. Their mean endometrial thickness was 4.9 mm, and they had an echogenic endometrium and thin uterine crosses. Between May 1998 and April 1999, treatment consisted of 800 mg of PTX combined with 1,000 IU of Vit.E daily for at least 9 months. Endometrial thickness, echogenicity, and pulsatility index of the uterine arteries, assessed by ultrasound and Doppler before and after treatment, and embryo implantation by IVF-OD. PTX-Vit.E treatment was well tolerated and induced improvements, as mean edematous endometrial thickness increased to 7.4 mm, with nice uterine crosses. Three frozen-thawed ETs resulted in two viable pregnancies. In women with POF and uterine resistance to HRT, combined PTX-Vit.E reduces fibroatrophic uterine lesions and improves the uterine response to HRT, thus allowing embryo implantation and ongoing pregnancy.

    The aim of this study was to measure the level of Vitamin K2 (Vit K2) in osteoporotic patients and individuals with normal bone density as controls. This case-control study was done in Outpatient Department of Rheumatology at Qazvin Boo-ali Sina Hospital in 2013. Participants were 50 patients with osteoporotic densitometry measured by DEXA (T score? -2.5) who were matched with 48 persons in control group with normal bone density (T score> -1). The level of Vit K2 in samples was measured using enzyme linked immunosorbent assay (ELISA). Data were analyzed by Mann-Whitney U test and Chi-square test. The level of Vit K2 in patients with osteoporosis was not significantly different from the control group (Median: 75.95 vs. 71.35 nmol/L, respectively; P-value: 0.709). The authors determined cut-offs 75 percentile of vitamin K2 in all participants that was 85 nmol/L and percentages of persons in two groups were similar. Although Vit K2 level in patients with osteoporosis was not significantly different from the control group, further studies are necessary to confirm the association of osteoporosis and Vit K2.

    2017-09-01

    The binding affinity between vitamin B12 (VitB12) and bovine serum albumin (BSA) has been investigated in aqueous solution at pH = 7.4, employing UV-vis absorption and steady-state, synchronous and three-dimensional fluorescence spectra techniques. Representative effects noted for BSA intrinsic fluorescence resulting from the interactions with VitB12 confirm the formation of π-π stacked non-covalent and non-fluorescent complexes in the system VitB12-BSA. All the determined parameters, the binding, fluorescence quenching and bimolecular quenching rate constants (of the order of 104 L mol- 1, 103 L mol- 1 and 1011 L mol- 1 s- 1, respectively), as well as Förster resonance energy transfer parameters validate the mechanism of static quenching. The interaction with VitB12 induces folding of the polypeptide chains around Trp residues of BSA, resulting in a more hydrophobic surrounding. Presented outcomes suggest that the addition of VitB12 can lead to the more organized BSA conformation and its more folded tertiary structure, what could influence the physiological functions of bovine serum albumin, notably in case of its overuse or abnormal metabolism.

    Full Text Available Abstract Background The status of α-tocopherol (vit E and selenium (Se has been shown to influence disease resistance in pigs, and may be important for the health of weanling pigs. Methods Plasma levels of both vit E and Se were followed in weanling pigs under field conditions in six Norwegian pig herds. Plasma vit E and Se were measured in 3 sows from each herd and 4 piglets in the litter of each sow at the day before weaning (day -1; and in the same piglets at days 4, 8 and 18 after weaning. Results Mean plasma vit E was 4.0 μg/ml in the sows and 2.6 μg/ml in the piglets at day -1, fell to 1.6 μg/ml in the weanling pigs at day 4, and remained low. Mean plasma Se was 0.22 μg/g in the sows and 0.08 μg/g in the piglets at day -1, rose to 0.10 μg/g in the weanlings at day 4, and continued rising. Conclusion The results suggest that vit E and Se supplementation to piglets and weanling pigs in Norway may still be suboptimal, but that levels of the two nutrients partially compensate for each other in the weaning period.

    Full Text Available This study was aimed to assess the protective effects of Cornus mas fruit extract (CMFE and vitamin E (Vit E on sperm quality parameters in the methotrexate (MTX-treated mice. Forty-eight young adult male mice (8-12 weeks were randomly divided into six groups including control and test groups. The control group received normal saline orally , and the test groups were treated MTX (20 mg kg-1, ip, once weekly, MTX + CMFE (250 mg kg-1, MTX + CMFE (500 mg kg-1, MTX + CMFE (1000 mg kg-1, and MTX + Vit E (100 IU kg-1, po for 35 consecutive days. On day 35, after euthanasia the epididymal sperms were isolated. Then the total mean sperm count, sperm viability and motility were determined. The total antioxidant capacity (TAOC of all experimental groups were also evaluated. The MTX-treated animals showed a significant changes in all parameters of sperm quality assessment compared to the control group. Both Vit E and CMFE were able to protect from MTX-induced effects on sperm maturity and DNA damage. Co-administration of MTX and CMFE and/or Vit E resulted in protection from MTX-reduced TAOC. In conclusion, these data suggested that MTX administration could adversely affect the sperm quality. Moreover, the protective effect of Vit E and CMFE on MTX-induced sperm toxicity was also documented.

    Little is known about the Hymenoptera venom allergy impact on work ability and the effect of venom immunotherapy (VIT) on work. The objective of this study was to evaluate the prevalence and predictors of work disability in patients treated with VIT and the effects of VIT on occupational functioning. 181 patients, aged 18-71 years, treated with VIT while working, were investigated by questionnaire. Participants were classified into employed and self-employed and, based on work exposure to Hymenoptera, into three risk categories: high risk, occasionally high risk and low risk. Work disability was defined as having to have changed jobs/tasks and/or suffered economic loss because of Hymenoptera venom allergy. Predictors of work disability were assessed in logistic regression models. 31 (17%) patients reported work disability. Being self-employed and having the severe reaction at work were associated with work disability (pallergy could determine work disability. Patients with Hymenoptera venom allergy having a high-risk job for exposure to Hymenoptera seem to have higher risk of work disability and refer more frequently a positive effect of VIT on work.

    As the endothelium ages it may become more susceptible to damage by atherogenic plasma components such as toxic lipid oxidation products. Vitamin E (vit E) might prove to be anti-atherogenic by reducing oxidative injury. This study investigated the effects of age and chronic exposure to fatty acid hydroperoxides (OFA) and/or vit E on endothelial barrier function (EBF) and cell growth characteristics. Chronic exposure to 5 microM OFA for 40 passages resulted in an age-related decrease in EBF, while supplementation of OFA-treated cultures with 25 microM vit E protected against the OFA-mediated decrease in EBF, independent of cell age. Vit E treatment alone had no significant effect on EBF relative to control cultures. No changes in growth characteristics, i.e., total DNA or protein per culture, were noted, regardless of treatment, although total DNA per culture decreased with increasing culture passage. These results suggest that chronic oxidative stress decreases EBF, predisposing the artery to infiltration by blood components and subsequent atherogenesis and that vit E delays cumulative changes in EBF related to chronic OFA exposure.

    In order to increase the rate of successful functional MR studies in children it is helpful to shorten the time spent in the scanner. To this effect, assessing two cognitive functions with one task seems to be a promising approach. The hypothesis of this study was that the control condition of an established language task (vowel identification task, VIT) requires visuospatial processing and that the control condition (VIT(CC)) therefore may also be applicable to localize visuospatial functions. As a reference task, a visual search task (VST, previously established for use in children) was employed. To test this hypothesis, 43 children (19 f, 24 m; 12.0±2.6, range 7.9 to 17.8 years) were recruited and scanned using both tasks. Second-level random effects group analyses showed activation of left inferior-frontal cortex in the active condition of the VIT, as in previous studies. Additionally, analysis of the VIT(CC) demonstrated activation in right-dominant superior parietal and high-frontal brain regions, classically associated with visuospatial functions; activation seen in the VST was similar with a substantial overlap. However, lateralization in the parietal lobe was significantly more bilateral in the VST than in the VIT(CC). This suggests that the VIT can not only be applied to assess language functions (using the active>control contrast), but also that the control>active condition is useful for assessing visuospatial functions. Future task design may benefit from such a "dual use" approach to performing fMRI not only, but also particularly in children. Copyright © 2011 Elsevier Inc. All rights reserved.

    Full Text Available Sian W Ludman,1 Robert J Boyle2 1Paediatric Allergy Department, St Mary's Hospital, Imperial Healthcare NHS Trust, London, UK; 2Department of Paediatrics, Imperial College London, London, UKAbstract: Systemic allergic reactions to insect stings affect up to 5% of the population during their lifetime, and up to 32% of beekeepers. Such reactions can be fatal, albeit very rarely, and fear of a further systemic reaction (SR can lead to significant anxiety and quality of life impairment. A recent Cochrane systematic review confirmed that venom immunotherapy (VIT is an effective treatment for people who have had a systemic allergic reaction to an insect sting. VIT reduces risk of a further SR (relative risk 0.10, 95% confidence interval 0.03–0.28, but VIT also reduces risk of a future large local reaction, and significantly improves disease-specific quality of life. However, health economic analysis showed that VIT is generally not cost effective for preventing future SRs; most people are stung infrequently, most SRs resolve without long-term consequences, and a fatal outcome is extremely rare. VIT only becomes cost effective if one is stung frequently (eg, beekeepers or if quality of life improvement is considered. Thus, for most people with insect sting allergy, anxiety and quality of life impairment should be the overriding consideration when making treatment decisions, highlighting the importance of a patient-centered approach. Areas which need to be explored in future research include efforts to improve the safety and convenience of VIT such as the use of sublingual immunotherapy; quality of life effects of venom allergy in children and adolescents as well as their parents; and the optimal duration of treatment.Keywords: anaphylaxis, quality of life

  9. Correlation between follicular fluid levels of sRAGE and vitamin D in women with PCOS.

    The pro-inflammatory advanced glycation end products (AGEs) and their anti-inflammatory soluble receptors, sRAGE, play a role in the pathogenesis of PCOS. There is a correlation between vitamin D (vit D) and sRAGE in the serum, whereby vit D replacement increases serum sRAGE levels in women with PCOS, thus incurring a protective anti-inflammatory role. This study aims to compare levels of sRAGE, N-carboxymethyl-lysine (CML; one of the AGEs), and 25-hydroxy-vit D in the follicular fluid (FF) of women with or without PCOS, and to evaluate the correlation between sRAGE and 25-hydroxy-vit D in the FF. Women with (n = 12) or without (n = 13) PCOS who underwent IVF were prospectively enrolled. Women with PCOS had significantly higher anti-Mullerian hormone levels, higher number of total retrieved and mature oocytes, and higher number of day 3 and day 5 embryos formed. Compared to women without PCOS, women with PCOS had significantly lower FF sRAGE levels. In women with PCOS, in women without PCOS, and in all participants together, there was a significant positive correlation between sRAGE and 25-hydroxy-vit D. sRAGE positively correlated with CML in women without PCOS but not in women with PCOS. In women with PCOS, the low ovarian levels of the anti-inflammatory sRAGE suggest that sRAGE could represent a biomarker and a potential therapeutic target for ovarian dysfunction in PCOS. Whether there is a direct causal relationship between sRAGE and vit D in the ovaries remains to be determined.

    We have used on-line microdialysis sampling coupled with high-performance liquid chromatography and UV-vis detection to simultaneously determine the contents of ascorbyl glucoside (AA-2G), kojic acid (KA), and niacinamide (VitB(3)) in commercial bleaching cosmetics. Our results indicate that AA-2G, KA, and VitB(3) separated well within 4.5 min on a reverse-phase Hypersil Fluophase PFP column when eluting with 0.020 M phosphate buffer solution in 40% (v/v) methanol at pH 5.5. The calibration curves were linear over the ranges 0.068-304, 0.071-284, and 0.024-488 microg mL(-1) for AA-2G, KA, and VitB(3), respectively, with correlation coefficients for the linear regression analyses falling within the range 0.9982-0.9999. The detection limits for AA-2G, KA, and VitB(3) were 0.01, 0.01, and 0.007 microg mL(-1), respectively. The detection wavelength was robust when the levels of the analytes in the samples were high (0.1-2%). The analytes were all detected using ultraviolet light (254 nm). The compounds diffuse through the membrane more readily when KA and VitB(3) are in their molecular forms and AA-2G is ionized. The recoveries were in the range 92-106% with good reproducibility (R.S.D.=3.9-8.7%). We used this procedure to assay six commercially available bleaching cosmetics; our results confirmed not only the precision of the method but also the claims made on the labels of the cosmetics. This approach provides a very simple means to determine the contents of AA-2G, KA, and VitB(3) in various dosages in bleaching cosmetics.

    Using conventional MRI methods, the differentiation of primary cerebral lymphomas (PCNSL) and other primary brain tumors, such as glioblastomas, is difficult due to overlapping imaging characteristics. This study was designed to discriminate tumor entities using normalized vascular intratumoral signal intensity values (nVITS) obtained from pulsed arterial spin labeling (PASL), combined with intratumoral susceptibility signals (ITSS) from susceptibility-weighted imaging (SWI). Thirty consecutive patients with glioblastoma (n = 22) and PCNSL (n = 8), histologically classified according to the WHO brain tumor classification, were included. MRIs were acquired on a 3 T scanner, and included PASL and SWI sequences. nVITS was defined by the signal intensity ratio between the tumor and the contralateral normal brain tissue, as obtained by PASL images. ITSS was determined as intratumoral low signal intensity structures detected on SWI sequences and were divided into four different grades. Potential differences in the nVITS and ITSS between glioblastomas and PCNSLs were revealed using statistical testing. To determine sensitivity, specificity, and diagnostic accuracy, as well as an optimum cut-off value for the differentiation of PCNSL and glioblastoma, a receiver operating characteristic analysis was used. We found that nVITS (p = 0.011) and ITSS (p = 0.001) values were significantly higher in glioblastoma than in PCNSL. The optimal cut-off value for nVITS was 1.41 and 1.5 for ITSS, with a sensitivity, specificity, and accuracy of more than 95%. These findings indicate that nVITS values have a comparable diagnostic accuracy to ITSS values in differentiating glioblastoma and PCNSL, offering a completely non-invasive and fast assessment of tumoral vascularity in a clinical setting.

    Adverse systemic reactions (SRs) are more common in honeybee venom immunotherapy (VIT) than in wasp VIT. Factors that might be associated with SRs during the honeybee VIT are poorly understood. Our aim was to evaluate risk factors for SRs during the build-up phase of honeybee venom immunotherapy. We included 93 patients who underwent ultra-rush honeybee VIT. The adverse SRs and their severity was compared to various immunological (sIgE, tIgE, basophil CD63 response, baseline tryptase, and skin tests), patient-specific (age, sex, cardiovascular conditions and medications, and other allergic diseases), and sting-specific factors (anaphylaxis severity, time interval to onset of symptoms, and absence of cutaneous symptoms). Twenty-three patients (24.7%) experienced mild SRs and 13 patients (14%) severe SRs. In five patients with severe SRs, the build-up was stopped. High basophil allergen sensitivity, evaluated as dose-response curve metrics of EC15, EC50, CD-sens, AUC, or the response to submaximal 0.01 μg/mL of venom concentration, was the most significant risk factor and only independent predictor of severe SRs and/or build-up stop. Time interval of build-up phase of honeybee VIT. Possibly role was also showed for short latency to filed sting reaction and low sIgE to rApi m1. Before honeybee VIT, measurement of basophil allergen sensitivity should be used to identify patients with a high risk for severe side-effects. © 2015 John Wiley & Sons Ltd.

    Background: This study was aimed to assess the effects of angiotensin II (Ang II) supplementation to the In Vitro Maturation (IVM) and In Vitro Culture (IVC) media of vitrified-warmed ovine oocytes on their developmental competence and expression of Na+/K+/ATPase in resulting embryos. Methods: The slaughterhouse-derived immature oocytes (n=1069) were randomly distributed into four experimental groups: groups I and II) IVM/IVF and IVC of fresh and vitrified oocytes without angiotensin supplementation (Control-Fresh and Control-Vit groups, respectively); group III) IVM of vitrified oocytes in the presence of Ang II followed by IVF/IVC (Vit-IVM group); and group IV) IVM/IVF of vitrified oocytes followed by IVC wherein the embryos were exposed to Ang II on day 4 of IVC (Vit-D4 group). The embryos were immunostained with primary antibodies against Na+/K+/ATPase α1 and β1 subunits. Results: In Vit-IVM and Vit-D4 groups, the rates of expanded and total blastocysts on day 7 as well as the proportion of blastocysts on day 8 were increased. The expression of Na+/K+/ATPase α1 and β1 subunits were positively influenced by the addition of Ang II on day 4 (Vit-D4 group). Conclusion: The addition of Ang II to the IVM and IVC media could improve blastocysts formation in vitrified sheep oocytes. This improvement might be related to the greater expression of Na+/K+/ATPase α1 and β1 subunits when Ang II was added during IVC. PMID:27563427

The present study was carried out to evaluate the potential protective role of vitamin E (vit E or selenium against MSG induced oxidative stress and histopathological changes in testis tissues of rats. Mature male Wistar rats weighing 150–200 g BW were allocated to evenly twelve groups each group of ten animals, the first group was maintained as control group, the 2nd, 3rd and 4th groups were administered MSG in three different dose levels (low, medium and high (6, 17.5 and 60 mg/kg BW, the 5th and 6th groups were given vit E in two doses (low and high (150 and 200 mg/kg, the 7th and 8th groups were administered selenium in two doses (low and high (0.25 and 1 mg/kg daily via gavage for a period of 30 days. Meanwhile the 9th and 10th groups were given combinations of MSG (high dose and vit E while, the 11th and 12th groups were given MSG (high dose plus selenium in two recommended doses for each one. Monosodium glutamate caused an elevation in lipid peroxidation level parallel with significant decline in SOD, CAT as well as GPx activities in testis tissues. Administration of vit E or selenium to MSG-treated groups declined lipid peroxidation, increased SOD, CAT, GPx activities. Selenium or vit E significantly reduced MSG induced histopathological changes by the entire restoration of the histological structures and the testicular antioxidant status to great extent in treated rats. In conclusion, supplementation of selenium or vit E could ameliorate the MSG induced testicular toxicity to great extent and reduce the oxidative stress on testis tissues.

    Sodium azide (SA) is used as an active ingredient to control a broad spectrum of soil borne pathogens including insects, weeds, nematodes, fungi, and bacteria. The purpose of this study was to evaluate the ameliorator property of vitamin E (Vit E) or/and selenium (Se) against SA-induced injury in male mice at the biochemical, immunological and histological levels. The mice were divided into nine groups (10/group). The first three groups were served as control, Vit E and Se while, the second three groups were treated with three different doses of SA. The last three groups were treated with high dose of SA with Vit E or Se or Vit E and Se and all animals were treated for a period of 30 days. Exposure to SA at the three doses to mice led to an alternation of liver and kidney functions, decrease the testosterone concentration, decreased IgG and IgM levels as well as the increasing the TNF-α. The effects of SA on the biochemical parameters of mice were dose-dependent. Administration of Se or/and Vit E to SA-treated mice attenuates the toxicity of this compound, objectified by biochemical and histological improvement of liver, kidney and testis. But, the alleviation is more pronounced with the both antioxidants. Thus, the synergistic effect of Se and Vit E is most powerful in reducing the toxicity induced by SA and improving the humoral immune response of mice. Copyright © 2014 Elsevier GmbH.

    To describe (i) the clinical characteristics of workers, exposed to hymenoptera stings, with an ascertained diagnosis of Hymenoptera Venom Allergy (HVA), (ii) the specific role of occupational exposure, (iii) the effect of Venom Immunotherapy (VIT) in reducing the severity of allergic episodes in workers exposed to repeated stings of hymenoptera, and (iv) the management of the occupational consequences caused by allergic reactions due to hymenoptera stings. Between 2000 and 2013 an observational study, including patients referred to the regional reference hospital of Liguria, Italy, with an ascertained diagnosis of HVA and treated with VIT, was performed. A structured questionnaire was administered to all patients to investigate the occupational features of allergic reactions. These were graded according to standard systems in patients at the first episode, and after re-stings, during VIT. One-hundred and 8four out of the 202 patients referred had a complete data set. In 32 (17.4%) patients, the allergic reaction occurred during work activities performed outdoor. Of these, 31.2% previously stung by hymenoptera at work, and receiving VIT, were re-stung during occupational activity. The grades of reaction developed under VIT treatment resulted clinically less severe than of those occurred at the first sting (p-value = 0.031). Our findings confirmed the clinical relevance of HVA, and described its occupational features in outdoor workers with sensitization, stressing the importance of an early identification and proper management of the professional categories recognized at high risk of hymenoptera stings. The Occupational Physician should be supported by other specialists to recommend appropriate diagnostic procedures and the prescription of VIT, which resulted an effective treatment for the prevention of episodes of severe reactions in workers with a proven HVA.

    Low lamb recruitment is a major challenge facing managers attempting to mitigate the decline of bighorn sheep (Ovis canadensis), and investigations into the underlying mechanisms are limited because of the inability to readily capture and monitor bighorn sheep lambs. We evaluated 4 capture techniques for bighorn sheep lambs: 1) hand-capture of lambs from radiocollared adult females fitted with vaginal implant transmitters (VITs), 2) hand-capture of lambs of intensively monitored radiocollared adult females, 3) helicopter net-gunning, and 4) hand-capture of lambs from helicopters. During 2010–2012, we successfully captured 90% of lambs from females that retained VITs to ≤1 day of parturition, although we noted differences in capture rates between an area of high road density in the Black Hills (92–100%) of South Dakota, USA, and less accessible areas of New Mexico (71%), USA. Retention of VITs was 78% with pre-partum expulsion the main cause of failure. We were less likely to capture lambs from females that expelled VITs ≥1 day of parturition (range = 80–83%) or females that were collared without VITs (range = 60–78%). We used helicopter net-gunning at several sites in 1999, 2001–2002, and 2011, and it proved a useful technique; however, at one site, attempts to capture lambs led to lamb predation by golden eagles (Aquila chrysaetos). We attempted helicopter hand-captures at one site in 1999, and they also were successful in certain circumstances and avoided risk of physical trauma from net-gunning; however, application was limited. In areas of low accessibility or if personnel lack the ability to monitor females and/or VITs for extended periods, helicopter capture may provide a viable option for lamb capture.

    Full Text Available The objective of this study was to evaluate the effects of different maturation systems on oocyte resistance after vitrification and on the phospholipid profile of the oocyte plasma membrane (PM. Four different maturation systems were tested: 1 in vitro maturation using immature oocytes aspirated from slaughterhouse ovaries (CONT; n = 136; 2 in vitro maturation using immature oocytes obtained by ovum pick-up (OPU from unstimulated heifers (IMA; n = 433; 3 in vitro maturation using immature oocytes obtained by OPU from stimulated heifers (FSH; n = 444; and 4 in vivo maturation using oocytes obtained from heifers stimulated 24 hours prior by an injection of GnRH (MII; n = 658. A sample of matured oocytes from each fresh group was analyzed by matrix associated laser desorption-ionization (MALDI-TOF to determine their PM composition. Then, half of the matured oocytes from each group were vitrified/warmed (CONT VIT, IMA VIT, FSH VIT and MII VIT, while the other half were used as fresh controls. Afterwards, the eight groups underwent IVF and IVC, and blastocyst development was assessed at D2, D7 and D8. A chi-square test was used to compare embryo development between the groups. Corresponding phospholipid ion intensity was expressed in arbitrary units, and following principal components analyses (PCA the data were distributed on a 3D graph. Oocytes obtained from superstimulated animals showed a greater rate of developmental (P0.05 for all groups (CONT VIT = 2.8±3.5%, IMA VIT = 2.9±4.0%, FSH VIT = 4.3±7.2% and MII VIT = 3.6±7.2%. MALDI-TOF revealed that oocytes from all maturation groups had similar phospholipid contents, except for 760.6 ([PC (34:1 + H]+, which was more highly expressed in MII compared to FSH (P<0.05. The results suggest that although maturation systems improve embryonic development, they do not change the PM composition nor the resistance of bovine oocytes to vitrification.

    In anorexia nervosa (AN), osteoporosis and osteopenia are common, which have been associated with low circulating levels of vitamin D (VitD) in other settings. We aimed to meta-analyze cross-sectional studies reporting on VitD parameters in patients with AN and healthy controls (HCs). Electronic PubMed search from database inception until December 31, 2013 and meta-analysis of cross-sectional studies comparing serum levels of 25-hydroxyvitamin D (25OH-D), 1,25-dihydroxyvitamin D (1,25OH-D) and dietary VitD between patients with AN and HCs, before or after VitD supplementation. We calculated random effects standardized mean differences (SMDs) ±95% confidence intervals (CIs) as effect size measures. Out of 1,739 initial hits, 15 studies with a total of 927 participants (AN = 408 and HCs = 519) were meta-analyzed. In the unsupplemented state, both serum 25OH-D (studies = 4; n = 168; SMD = -0.43; 95%CI: -0.83 to -0.03; p = .03) and 1,25OH-D levels (studies = 4; n = 113; SMD = -1.06; 95%CI: -1.47 to -0.66; p supplementation, serum 25OH-D levels were significantly higher than in HCs (studies = 5; n = 449; SMD = 0.66; 95%CI: 0.01-1.31; p = .05). Paradoxically, despite lower 25OH-D and 1,25OH-D levels, AN patients reported similar intake of VitD compared to HCs (studies = 6; n = 314; SMD = 0.33; 95%CI: -0.16, 0.81; p = .19). Although AN patients reported similar dietary VitD intake compared to HCs, AN patients had significantly lower 25OH-D and 1,25OH-D levels without supplementation. Conversely, supplementation with cholecalciferol fully normalized VitD serum levels. Future studies are needed to clarify the role of VitD supplementation in AN for improving bone health. © 2014 Wiley Periodicals, Inc.

    Vitamin D (vitD) deficiency is linked to many disease states including rickets and cancer, and vitD supplementation to improve response to cancer therapy has been explored. Supplementation may be most appropriate for dogs with suboptimal vitD concentrations. In dogs, the primary source of vitD is diet (predominantly via commercial dog food). Our goal was to determine how food source and supplements affect 25(OH)D concentrations, the storage form of vitD. Serum was collected from clinically healthy dogs, and pet owners were surveyed about food source and supplements. Serum 25(OH)D concentration was measured using a quantitative chemiluminescent assay (LIASON, DiaSorin, Stillwater, MN). Dogs (n = 320) were tested for serum 25(OH)D concentrations (range 9.5-249.2 ng/mL). Dogs were fed commercial diets from forty different manufactures (n = 292); additionally some dogs were fed homemade diets (n = 18) or a combination of commercial and homemade diets (n = 10). Median serum 25(OH)D concentrations in dogs fed commercial foods ranged from 47.4 to 100.1 ng/mL with an overall median of 67.9 ng/ml (CV 29%). Analysis for differences among manufacturers was significant (P = 0.0006). Serum 25(OH)D concentrations amongst dogs fed homemade diets had the largest range (9.5-129 ng/mL) and the lowest value (9.5 ng/mL). Dogs receiving salmon oil as a supplement (n = 22) had significantly higher serum 25(OH)D (on average a 19.6 ng/mL increase) than those not receiving a supplement (P = 0.007). Serum 25(OH)D concentrations in dogs vary widely which likely reflects varying dietary vitD content. Notable differences exist among manufacturers and brands and may reflect differences in proprietary formulations. Given the variability of measured serum 25(OH)D concentrations in dogs and the importance vitD appears to have on health status, dietary vitD content should be optimized.

    2010-10-01

    To perform a systematic review and meta-analysis of the effectiveness of combined vitamin C and E (vitCE) supplementation for the prevention of preeclampsia. PubMED, Web of Science, and Cochrane Central Register of Controlled Trials from inception through June 2010, and bibliographies of review articles and eligible studies. Fifteen eligible studies that evaluated vitCE supplementation for the prevention of preeclampsia were identified. On the basis of prespecified inclusion and exclusion criteria, 9 were included in the meta-analysis. All were randomized controlled trials. The reporting and methodologic quality of the included studies was assessed with the CONSORT checklist and the Jadad scale. The 9 included studies had moderate-to-high CONSORT and Jadad scores. The incidence of preeclampsia was 9.7% (949 of 9833) in the vitCE group and 9.5% (946 of 9842) in the placebo group. A random effects model was used for pooling and no difference was found in the relative risk (RR) of preeclampsia between the vitCE and placebo groups (RR: 0.98; 95% confidence interval [CI]: 0.87-1.10). The incidence of gestational hypertension was 22.6% (1915 of 8491) in the vitCE group and 20.3% (1728 of 8500) in the placebo group (RR: 1.11, 95% CI: 1.05-1.17). The incidence of placental abruption was 0.58% (43 of 7379) in the vitCE group and 0.87% (64 of 7361) in the placebo group (RR: 0.67, 95% CI: 0.46-0.98). No significant differences were observed for other maternal and neonatal outcomes. Combined VitCE supplementation does not decrease the risk of preeclampsia and should not be offered to gravidas for the prevention of preeclampsia or other pregnancy induced hypertensive disorders. Furthermore, combined supplementation with vitCE increased the risk of GH but decreased the risk of placental abruption. However, these latter associations may not be causal, especially since they were the product of multiple statistical comparisons, and the 95% CI around the point estimates almost

    The present study investigates the potential of layer by layer coated calcium phosphate nanoparticles - for oral delivery of insulin where Vitamin B12 grafted chitosan and sodium alginate have been used as cationic and anionic polyelectrolyte respectively. The major emphasis has been given on the role Vitamin B12 conjugated chitosan as cationic polyelectrolyte (VitB12-Chi) in the delivery system. VitB12-Chi conjugate was prepared by carbodiimide reaction. The formulated VirB12-Chi-CPNPs were tested for in vitro and in vivo efficacy studies carried out in Caco-2 monolayers and diabetic rats. VitB12-Chi-CPNPs with particle size insulin release at simulated gastric fluid and simulated intestinal fluid. Fluorescence microscopy and flow cytometry studies revealed higher uptake of VitB12-Chi-CPNPs in Caco-2 monolayer in comparison to Chi-CPNPs. Further reduction in TEER supported paracellular transport of insulin because of opening of tight epithelial junctions. In vivo intestinal uptake of FITC tagged Vit-B12-Chi-CPNPs from different intestinal segments supported paracellular and receptor mediated uptake of VitB12-Chi-CPNPs. Plasma insulin and blood glucose levels were measured in diabetic rats and showed about four fold increases in insulin bioavailability and sustained hypoglycemic effects up to 12h of administration with VitB12-Chi-CPNPs in comparison to Chi-CPNPs. Results of the study revealed the potential of layer by layer nanoparticles for oral insulin delivery. The study also specifically highlighted the role of VitB12 as a pH sensitive and targeting ligand which significantly participated in enhancing insulin oral bioavailability. Oral delivery of insulin is always the most desirable approach for diabetic patients however it's also the most challenging in respect to formulation development due to harsh gastrointestinal conditions. Several groups have been working from decades for oral delivery of insulin. However the beauty of this prototype formulation is that

    Vitamin D deficiency is thought to impair insulin action and glucose metabolism; however, previous studies have not examined ethnic differences. We investigated a cohort of predominantly white Greek Caucasian and Bangladeshi immigrant patients with diabetes mellitus in order assess the association between diabetes mellitus and 25-hydroxyvitamin D [25(OH)VitD]. A total of 165 patients from Bangladesh and 118 patients from Greece with diabetes were assessed for diabetes and 25(OH)VitD status. The 25(OH)VitD levels of Bangladeshi patients were significantly lower compared to Greek patients (12.42±5.86 ng/ml vs. 23.06±12.36 ng/ml, p<0.001). Only 1.2% of Bangladeshi patients vs. 24.57% of Greek patients had sufficient levels of 25(OH)VitD (≥30 ng/ml) The prevalence of vitamin D deficiency is very high amongst patients with diabetes but immigrants are at greater risk. Vitamin D supplementation could be valuable in the prevention or treatment of diabetes. Copyright © 2015 International Institute of Anticancer Research (Dr. John G.

Four levels of vitamin-mineral supplementation were used (T1-control diet (60/30 IU of vit E for starter and growing diet, respectively, zero vit. C, 80 ppm of inorganic Zn, 0.3 ppm of inorganic Se; T2-control diet + 100 UI vit E and 300 ppm vit C/kg; T3-control diet + 40 ppm Zn and 0,3 ppm Se/kg; T4-control diet + T2 and T3 levels and two environments - thermoneutral and cyclic heat stress (TN and HS from 14 to 35 days of age. In the period when part of the birds was submitted to HS, from 14 to 35 days, it was observed lower feed intake (FI and better feed conversion (FC for HS birds receiving supplementation compared to the group without supplementation. Evaluating the total period, all the types of supplementation provided lower FI and better FC than the control treatment, but not affected weight gain (WG. The supplementation of vitamins C and E and/or organic minerals Zn and Se improved the performance of birds due to a lower FI resulting in better FC, independently on the environment.

    The prognostic improvement attributed to genetic markers over current prognostic system has not been well studied for melanoma. The goal of this study is to evaluate the added prognostic value of Vitamin D Pathway (VitD) SNPs to currently known clinical and demographic factors such as age, sex, Breslow thickness, mitosis and ulceration (CDF). We utilized two large independent well-characterized melanoma studies: the Genes, Environment, and Melanoma (GEM) and MD Anderson studies, and performed variable selection of VitD pathway SNPs and CDF using Random Survival Forest (RSF) method in addition to Cox proportional hazards models. The Harrell's C-index was used to compare the performance of model predictability. The population-based GEM study enrolled 3,578 incident cases of cutaneous melanoma (CM), and the hospital-based MD Anderson study consisted of 1,804 CM patients. Including both VitD SNPs and CDF yielded C-index of 0.85, which provided slight but not significant improvement by CDF alone (C-index = 0.83) in the GEM study. Similar results were observed in the independent MD Anderson study (C-index = 0.84 and 0.83, respectively). The Cox model identified no significant associations after adjusting for multiplicity. Our results do not support clinically significant prognostic improvements attributable to VitD pathway SNPs over current prognostic system for melanoma survival.

    The object of this study was to determine the effect of prepartum supplementation of vitamin E with or without injective vitamin E and selenium (Se) on productive and reproductive performances and immune function in dairy cows. Sixty multiparous Holstein dairy cows were divided randomly into three groups at the end of gestation. Cows in each group received one of three treatments: (1) a single intramuscular (im) injection of vit. E + selenium 3 weeks prepartum; (2) daily supplementation of oral vit. E given from 3 weeks prepartum to parturition; (3) injective vit. E + Se with daily supplementation of oral vit. E. Blood samples were collected from cows at calving and from calves at 0 and 7 days of age. Concentration of IgG in serum of cows and calves as well as in colostrum was determined. No significant differences among treatments occurred in the concentrations of IgG, animal, and calf production and reproduction performance. Due to the lack of significant difference between injection and oral supplementation, it is recommended to replace the injection with oral supplementation.

    Vascular disease accounts for the majority of the clinical complications in diabetes mellitus. As an exaggerated oxidative stress degree has been postulated as the link between diabetes mellitus and endothelial function, a possible positive effect of plasma vitamin E (Vit.E) administration on brachial reactivity could be postulated. Our study aims at investigating the possible effect of chronic Vit.E administration on brachial reactivity, oxidative stress indexes, and intracellular magnesium and calcium content in type II diabetic patients free of diabetic complications. Forty adult, type II diabetic patients were enrolled in the study, which was deigned as a double blind, randomized vs. placebo trial. At baseline all patients underwent the following tests: 1) anthropometric and metabolic examinations, 2) evaluation of oxidative stress indexes, 3) intracellular magnesium and calcium measurements, and 4) determination of arterial compliance and distensibility. Then, all patients were randomly assigned to Vit.E treatment at a dose of 600 mg/day (Evion Forte; n = 20) or placebo (n = 20) over 8 weeks. At the end of this treatment period, a complete reevaluation of the patients was made. Vit.E treatment was associated with a significant improvement in the percent change in brachial artery diameter (Pmagnesium and calcium). After adjustment for age, sex, body mass index, and wait/hip ratio, all of these correlations remained significant (Preactivity in patients with type II diabetes mellitus. Such an effect seems mediated by a reduction in oxidative stress and a regulation of intracellular calcium and magnesium contents.

    Although psychomotor slowing is frequent in Alzheimer's disease (AD) and Lewy body dementia (LBD), its mechanism and diagnostic value have not been examined. To (i) assess psychomotor speed in patients with mild cognitive impairment (MCI), AD and LBD, (ii) determine the underlying mechanisms, and (iii) examine whether psychomotor slowing constitutes a useful diagnostic marker. Psychomotor speed was assessed in MCI (n = 11) and mild dementia due to AD (n = 23) or LBD (n = 18) and controls (n = 52) with visual inspection time (VIT), digital tapping, simple reaction time (SRT) and choice reaction time (CRT) tests. MCI did not differ from controls. Both dementia groups showed different patterns. In AD, VIT (p = 0.0001), tapping (p = 0.021), SRT (p = 0.0001) and decision time (p = 0.0001) were impaired as compared to controls. In LBD, VIT (p = 0.0001) was very impaired and correlated with visual hallucinations (p = 0.001); SRT lengthening (p = 0.0001) was related to attentional disorders (p = 0.0001). Psychomotor slowing of AD is due to slower perceptuomotor and decision processes. In LBD, psychomotor slowing is due to visual and attention disorders, and subtle visual disorders contribute to hallucinations. VIT and CRT are useful diagnostic markers.

    To investigate the therapeutic effects of vitamine B(6) (Vit B(6)) and Xuefu Zhuyu Decoction (XFZY, for activating blood circulation to remove stasis) in patients with localized scleroderma(LSD). Thirty-three patients were treated with XFZY and Vit B(6), with 15 cases taking orally prednisone acetate and 20 healthy volunteers as the control. Their level of soluble interleukin-2 receptor (sIL-2R) and tumor necrosis factor-alpha (TNF-alpha) in the patients with LSD before and after treatment were observed. The level of sIL-2R and TNF-alpha in the serum from the patients with LSD were higher than those of healthy volunteers (P < 0.01). After treatment with Vit B(6) and XFZY, the level of sIL-2R and TNF-alpha from the patients with LSD decreased significantly (P < 0.01), but there were no difference between the group taking Vit B(6) plus XFZY and the group given prednisone. The activating blood circulation to remove stasis approach in treating LSD with integrative Chinese and Western drugs got better results, and metabolic disorder of tryptophan might be correlated with the etiology of LSD.

    Oxidative stress occurs in many allergic and immunologic disorders as a result of the imbalance between the endogenous production of free reactive oxygen species (ROS) and/or the reduction of antioxidant defense mechanisms. Advanced glycation end products (AGEs), advanced oxidation protein products (AOPPs), and nitrosylated proteins (NPs) can be used as markers of oxidative stress and inflammation. Our objective was to examine the serum levels of AGEs, AOPPs, and NPs in patients with allergic reactions to hymenoptera venom before and after ultrarush venom immunotherapy (VIT). The study included two groups of patients: 30 patients allergic to yellow jacket or honey bee venom and treated by aqueous preparation of Vespula spp (26 patients) or Apis mellifera (four patients) VIT, and 30 healthy donors as controls. Blood samples were collected to measure serum levels of AGEs, AOPPs, and NPs at baseline (T1), at the end of the incremental phase of the VIT protocol (T2), and after 15 days (T3). Serum AOPP levels at T1 were significantly higher in comparison with controls (p = 0.001), whereas serum levels of NPs at T1 were significantly lower than those in controls (p venom allergy (HVA) is characterized by isolated episodes of reactions to stinging insect venom and is not included among chronic inflammatory diseases, an oxidative stress status occurs in patients suffering from this kind of allergy. Furthermore, VIT does not modify serum levels of these oxidative stress biomarkers.

    Anti-infective properties of biomedical materials are often achieved by loading or coating them with powerful bactericides. Undesirably, these bioactive molecules can damage the host cells at the biomaterial-tissues interface and, sometimes, even determine systemic toxic effects. The search for biomaterials able to actively resist infection while displaying a safe cytocompatibility profile toward eukaryotic cells is being progressively developed. Poly-(D,L)lactic acid (PLA) is a broadly used resorbable material with established biocompatibility properties. The dissolving surfaces of a biodegradable material tend to be per se elusive for bacteria. Here, films of pristine PLA, of PLA blended with vitamin E (VitE) and PLA blended with vitamin E acetate (VitE ac) were challenged in vitro with the biofilm-producers Staphylococcus epidermidis RP62A and Staphylococcus aureus ATCC25923. The bacterial adhesion properties of the different materials were investigated on small film disc specimens by a method based on microtiter plates. Adherent bacteria were quantified by both CFU plating and bioluminescence. Significant decrease in bacterial adhesion and biofilm accumulation was found on the surface of both the enriched polymers. These findings, together with the favorable intrinsic properties of PLA and the desirable bioactivities conferred by VitE, point up the VitE-blended PLA polymers as gentle anti-infective biomaterials. © 2014 Wiley Periodicals, Inc.

    Presence of vitrification method in sperm freezing and the introduction of solid surface vitrification beside rapid freezing in vapour, opens an easy and safe way to help infertility centres. While the effects of cryopreservation on motility, morphology and viability of sperm are documented, the question of the probable alteration of sperm DNA, chromatin and acrosome integrity after freezing and thawing procedures in different methods is still controversial. Normal sample were collected according to WHO strict criteria. Sperm suspensions were mixed 1:1 with 0.5 M sucrose and divided into four equal aliquots for freezing: fresh, nitrogen direct immersion vitrification (Vit), solid surface vitrification (SSV) and in vapour (Vapour). Sperm suspensions were transferred into a 0.25 ml sterile plastic. Then straw was inserted inside the 0.5 ml straw. For thawing, the straws were immersed in a 42 °C water bath. Beside the sperm parameters, we assessed the acrosome reaction by double staining, chromatin integrity by toluidine blue (Tb) and chromomycin A3 (CMA3) and DNA integrity by terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) respectively. In progressive motility, the highest rate occurred in Vit (39.9 ± 13.3). Moreover, the lowest rate of immotile sperm was in Vit (32.7 ± 16.3). In normal morphology, the group Vit was similar to the fresh, while SSV and Vapour were significantly different from the fresh. The percentage of acrosome-reacted sperms was more in Vit (81.3 ± 10.2) than the fresh group. TUNEL+ results showed that DNA fragmentation was significantly increased in Vit (p-value = 0.025). While in SSV and Vapour results were comparable to fresh. There was a significant correlation between TUNEL+ and normal morphology, TB, CMA3 and presence of intact acrosome. Sperm in Vapour was healthier in terms of DNA, chromatin and acrosome integrity. In contrast of higher motility and normal morphology; DNA, chromatin and acrosome

    Full Text Available Honey bee (Apis mellifera gene expression related to immunity for hymenoptaecin (AmHym and defensin-1 (AmDef-1, longevity for vitellogenin (AmVit2 and stem cell proliferation for poly U binding factor 68 kDa (AmPuf68 was compared following Varroa destructor parasitism, buffer injection and injection of V. destructor compounds in its homogenate. In adults, V. destructor parasitism decreased expression of all four genes, while buffer injection decreased expression of AmHym, AmPuf68 and AmVit2, and homogenate injection decreased expression of AmPuf68 and AmVit2 but increased expression of AmDef-1 relative to their respective controls. The effect of V. destructor parasitism in adults relative to the controls was not significantly different from buffer injection for AmHym and AmVit2 expression, and it was not significantly different from homogenate injection for AmPuf68 and AmVit2. In brood, V. destructor parasitism, buffer injection and homogenate injection decreased AmVit2 expression, whereas AmHym expression was decreased by V. destructor parasitism but increased by buffer and homogenate injection relative to the controls. The effect of varroa parasitism in brood was not significantly different from buffer or homogenate injection for AmPuf68 and AmVit2. Expression levels of the four genes did not correlate with detectable viral levels in either brood or adults. The results of this study indicate that the relative effects of V. destructor parasitism on honey bee gene expression are also shared with other types of stresses. Therefore, some of the effects of V. destructor on honey bees may be mostly due to wounding and injection of foreign compounds into the hemolymph of the bee during parasitism. Although both brood and adults are naturally parasitized by V. destructor, their gene expression responded differently, probably the result of different mechanisms of host responses during development.

    Full Text Available Objective To investigate the anti-fatigue effect and possible mechanisms of micronutrient compound. Methods One hundred and twenty-five male Kunming mice (SPF were fed following different feeding stuffs: sufficient feed, i.e. AIN-93M feed (corn starch 46.6%, casein 14%, dextrinized corn starch 15.5%, sucrose 10%, soybean oil 4%, fiber 5%, mineral mix 3.5%, vitamin mix 1%, L-cystine 0.18%, choline chloride 0.138% and tert-butylhydroquinone 8 ppm; insufficient feed (composed the same ingredients as the AIN-93M diet, replacing 30%, 50% or 70% of the content of mineral and vitamin mix with corn starch; compound micronutrient-added feed (CMAF, replacing 30% of the content of mineral and vitamin mix of AIN-93M diet with micronutrient compound composed of (g/kg Vit A 0.25, Vit B1 0.3, Vit B2 0.3, Vit B6 0.35, nicotinic acid 1.5, Vit D 0.05, Vit C 50, Vit E 10, calcium carbonate 180, ferrous glycine 1, zinc lactate 1 and corn starch 755.25. The mice were fed for 14 or 28 d, and then subjected to forced swim test with a load on their tails to exhaustion. The maximal swimming time was recorded. In another experiment, the Kunming mice were fed with corresponding feed for 28 d, and then subjected to forced swim test for 60 min, thereafter the samples of blood and liver were collected immediately. The serum contents of glucose, lactate, nonprotein nitrogen, nonesterified fatty acids and hepatic glycogen were measured. Results The dietary intake of 30% nutritional insufficient group (30% group was significantly decreased compared with normal control group (fed with AIN-93M diet, (P 0.05. The serum glucose and hepatic glycogen decreased and serum lactate, nonprotein nitrogen and nonesterified fatty acids increased in the control group, which were aggravated in nutrient insufficient group and reversed in micronutrient supplementation group. Conclusions Insufficient intake of micronutrients has significant influence on swimming endurance in mice and compound

    Low 25-hydroxy-vitamin D [25(OH)VitD] levels may represent a novel cardiovascular disease risk factor. Several statins may increase 25(OH)VitD concentration. The effect of other lipid-lowering drugs is unknown. To investigate whether switching to high-dose rosuvastatin, add-on-statin nicotinic acid or add-on-statin fenofibrate would alter 25(OH)VitD levels in patients with mixed dyslipidemia who are already on a conventional statin dose. This is a prespecified analysis of a previously published study. Forty-four patients with mixed dyslipidemia not at treatment goal despite treatment with simvastatin 10-40 mg or atorvastatin 10-20 mg or rosuvastatin 5-10 mg were randomly allocated to switch to rosuvastatin 40 mg (n=17), add-on-statin extended release nicotinic acid (ER-NA)/laropiprant (LRPT) (1000/20 mg first four weeks and 2000/40 mg thereafter) (n=14), or add-on-statin micronized fenofibrate (200 mg) for three months. The endpoint for this analysis was between-group difference in changes in 25(OH)VitD levels. Serum 25(OH)VitD levels did not significantly change in any group. In the switch to the highest dose of rosuvastatin group and the add-on-statin ER-NA/LRPT group there was an insignificant decrease in 25(OH)VitD levels {-4.7% [from 16.8 (3.2-37) to 16.0 (7.9-51.6)] and -14.8% [from 12.8 (2.0-54.8) to 10.9 (2.4-34)], respectively]}, while in the add-on-statin fenofibrate group there was an insignificant increase [+13% (from 14.5 (1.0-42) to 16.4 (4.4-30.4) ng/mL)]. No significant difference between groups was found. In patients already on a conventional statin dose, neither switching to high-dose rosuvastatin (40 mg) nor add-on-statin ER-NA/LRPT or fenofibrate were associated with significant changes in 25(OH)VitD serum levels.

    Venom immunotherapy (VIT) is highly effective in preventing allergic reactions to insect stings, but the appropriate venom must be used to achieve clinical protection. In patients with multiple positive results to venoms, molecular allergy diagnostics or CAP-inhibition may identify the causative venom. Concerning allergy to venom from Polistes spp. it has been proposed that only the European species P. dominulus should be used for VIT. However, this recommendation is not present in any international guideline. Using both laboratory and clinical data, we aimed to evaluate the reliability of this proposal. We performed an in vitro study using CAP-inhibition to determine sensitization of 19 patients allergic to Polistes venom. The clinical study included 191 patients with positive tests to Polistes treated with VIT, 102 were treated with P. dominulus and 89 were treated with a mix of American Polistes (mAP). The difference in % of inhibition was significant concerning inhibition of P. dominulus sIgE by P. dominulus venom (79.8%) compared with inhibition by mAP venom (64.2%) and not significant concerning the inhibition of mAP sIgE by P. dominulus venom (80.1%) and by mAP venom (73.6%). Instead, the clinical protection from stings was not statistically different between the two kinds of venom. The data from CAP inhibition would suggest that the choice of either P. dominulus venom or mAP venom for VIT is appropriate in patients with CAP inhibition higher than 70%, but the clinical data show the same odds of protection from stings using for VIT P. dominulus or mAP venom.

    A total of 240 female broilers (42 days old) were randomly assigned to four groups with six replicates and fed either a basal diet (two control groups) or a basal diet supplemented with either 1,200 μg Cr+3 from chromium (Cr) methionine/kg (Cr group) or 1,200 μg Cr+3 from Cr methionine plus 800 mg vitamin C (Vit C)/kg of diet (Cr + Vit C group). After 7 days on the dietary treatment, all groups except one of the controls were transported for 3 h under the summer conditions. Performance parameters were not influenced by dietary treatments. The plasma concentrations of insulin, triiodothyronine, triglyceride, and the ratio of triiodothyronine/thyroxin were decreased and the ratio of glucose/insulin was increased due to transport process. Road transportation also increased the plasma concentrations of protein, cholesterol, aspartate aminotransferase, and creatine kinase and decreased the concentration of low-density lipoprotein cholesterol in the Cr + Vit C group. The pretransport concentrations of insulin and triiodothyronine were highest in the Cr + Vit C group. The concentration of phosphorous was lower in the Cr group than that in the other groups after transport. No significant effects of dietary treatments were observed on the other biochemical parameters. Transport increased malondialdehyde concentration in the control group and did not change plasma total antioxidant capacity and erythrocyte glutathione peroxidase activity. Either in combination or alone, Cr increased plasma total antioxidant capacity (before transport P ≤ 0.05, after transport P = 0.07) but did not affect the concentration of malondialdehyde and activity of glutathione peroxidase. The duration of tonic immobility (TI) was similar between nontransported control chicks and transported chicks without any supplements. Pretreatment with Cr + Vit C significantly reduced the duration of TI.

    Full Text Available Objective: To study the vitamin E levels in preeclampsia placenta tissue and its correlation with oxidative stress injury and apoptosis. Methods: A total of 60 pregnant women with preeclampsia who received treatment and gave birth in our hospital between July 2012 and January 2016 were collected and divided into mild preeclampsia group (n=41 and severe preeclampsia group (n=19 according to the disease severity; 38 normal pregnant women who received pregnancy test and gave birth in our hospital during the same period were selected as healthy control group. The placental tissue samples of three groups of research subjects were retained, high performance liquid chromatograph-mass spectrometry was used to detect VitE levels in tissue grinding fluid, automatic biochemical analyzer was used to detect the levels of oxidative stress injury indexes, and fluorescence quantitative PCR method was used to detect the mRNA expression of apoptosis molecules. Results: VitE, SOD and CAT levels in grinding fluid of severe preeclampsia group were lower than those of mild preeclampsia group and healthy control group while ROS and AOPP levels were higher than those of mild preeclampsia group and healthy control group; Fas, caspase and Apaf-1 mRNA expression were higher than those of mild preeclampsia group and healthy control group while anti-apoptotic molecules Bcl-2, Bcl-xl, Mcl-2 and p57kip2 mRNA expression were lower than those of mild preeclampsia group and healthy control group. Spearman correlation analysis showed that VitE level in the preeclampsia placenta tissue was directly correlated with oxidative stress injury and cell apoptosis. Conclusion: VitE deficiency is the direct factor that results in oxidative stress and cell apoptosis in patients with preeclampsia, and the VitE supplementation in time is expected to become the auxiliary treatment means for patients with preeclampsia.

    Flowers of tulip cv. 'Murasakizuisho' have a purple perianth except for the bottom region, which is blue in color even though it has the same anthocyanin, delphinidin 3-O-rutinoside, as the entire perianth. The development of the blue coloration in the perianth bottom is due to complexation by anthocyanin, flavonol and iron (Fe), as well as a vacuolar iron transporter, TgVit1. Although transient expression of TgVit1 in the purple cells led to a color change to light blue, the coloration of the transformed cells did not coincide with the dark blue color of the cells of the perianth bottom. We thought that another factor is required for the blue coloration of the cells of perianth bottom. To examine the effect of ferritin (FER), an Fe storage protein, on blue color development, we cloned an FER gene (TgFER1) and performed expression analyses. TgFER1 transcripts were found in the cells located in the upper region of the petals along with purple color development by anthocyanin and were not found in the blue cells of the perianth bottom. This gene expression is in contrast to that of TgVit1, expressed only in the cells of the perianth bottom. Co-expression of TgVIT1 and TgFER-RNAi, constructed for suppressing endogenous TgFER1 by RNA interference (RNAi), changed the purple petal cells to a dark blue color similar to that of the natural perianth bottom. These results strongly suggest that TgVit1 expression and TgFER1 suppression are critical for the development of blue color in the perianth bottom.

    To compare perioperative parameters, safety, and short-term functional outcomes between GreenLight 180 W-XPS photoselective vaporization of the prostate (PVP) and vapor incision technique (VIT). A total of 956 men were treated at five high-volume centers in Canada and the United States between 2000 and 2014 for benign prostatic hyperplasia. Perioperative parameters, complications, and early functional outcomes were retrospectively compared. One-to-one propensity score matching was performed to adjust for baseline differences between treatment groups. Subgroup stratified comparative analysis was performed according to preoperative prostate volume 80 cc or less vs greater than 80 cc on transrectal ultrasound (259 and 185 patients, respectively). VIT allowed greater energy delivery and energy density, but operative time and laser time were longer with greater use of MoXy fibers when compared with PVP (all p < 0.05). Improvements in outcomes at 6 months, including International Prostate Symptom Score, quality of life score, and uroflowmetry parameters, were significantly greater after VIT when compared with baseline. VIT was associated with significantly greater 6-month prostate-specific antigen (PSA) reduction (63% vs 50%, p = 0.01). No differences in intraoperative complications were observed between treatment groups. VIT is safe and efficacious, providing greater improvements in functional outcomes and PSA reduction at 6 months in comparison with PVP. These results reflect the larger amount of adenoma removed. Yet, it is associated with longer operative time and greater use of MoXy fibers. Long-term follow-up is needed to accurately assess functional outcomes and retreatment rates.

    Data on the long-term outcome of children after specific venom immunotherapy (VIT) are limited. Therefore, we assessed sting recurrence and anaphylaxis relapse rates as well as adherence to anaphylaxis guidelines with regard to the availability of emergency equipment and education status. For this long-term survey, data of 311 children with a history of anaphylactic reactions to hymenoptera stings were collected by chart review. We included patients who were treated with a 3-year VIT between 1993 and 2009 and had completed a questionnaire. Forty of the 311 patients were included. Mean VIT duration was 3.1 years. Of the 40 patients included, 29 children (72.5%) received VIT with vespid venom, 9 with bee venom, and 2 patients with both venoms. During a mean follow-up period of 13 years, 20/40 patients (50%) suffered re-stings. Six of the 20 (30%) patients developed again anaphylactic symptoms (grade 1 n = 5, grade 3 n = 1); 2 were allergic to vespid and 4 to bee venom. Of the entire cohort, only 5/40 (12.5%) had appropriate emergency kits according to the guidelines of the European Academy of Allergy and Clinical Immunology. Among the patients who had emergency kits available, one third (5/15) felt uncertain about the correct application of the medication. Less than two thirds of our population (25/40) affirmed that they have been educated in emergency management. The vast majority (95%; 38/40) of our patients did not have allergy follow-ups after VIT completion. Anaphylactic relapses are not uncommon, and there are considerable deficits in the emergency management of patients. Hence, comprehensive standardized anaphylaxis education programs as well as regular follow-ups of the allergy status are crucial. © 2017 S. Karger AG, Basel.

    Hypertension is one of the primary modifiable risk factors for cardiovascular disease. Adequate vitamin D (vit D) levels have been shown to reduce vascular smooth muscle contraction and to increase arterial compliance, which may be beneficial in hypertension. Further, coenzyme Q10 (COQ10) through its action to lower oxidative stress has been reported to have beneficial effects on hypertension and heart failure. This study examined the possible cardiac and renal protective effects of vit D and COQ10 both separately and in combination with an angiotensin II receptor blocker, valsartan (vals) in l-NAME hypertensive rats. Hypertension was induced in rats by l-NAME administration. Following induction of hypertension, the rats were assigned into the following 6 subgroups: an l-NAME alone group and treated groups receiving the following drugs intraperitoneally for 6 weeks; vals, vit D, COQ10 and combination of vals with either vit D or COQ10. A group of normotensive rats were used as negative controls. At the end of the treatment period, blood pressure, serum creatinine, blood urea nitrogen, lipids and serum, cardiac and renal parameters of oxidative stress were measured. Compared to the l-NAME only group, all treatments lowered systolic, diastolic, mean arterial pressure, total cholesterol, low-density lipoprotein cholesterol, and creatinine levels as well as TNF-α and malondialdehyde. Further, the agents increased serum, cardiac and renal total antioxidant capacity. Interestingly, the combination of agents had further effects on all the parameters compared to treatment with each single agent. The study suggests that the additive protective effects of vit D and COQ10 when used alone or concurrent with vals treatment in hypertensive rats may be due to their effects as antioxidants, anticytokines and blood pressure conservers.

    The European Academy of Allergy and Clinical Immunology (EAACI) is in the process of developing the EAACI Guidelines on Allergen Immunotherapy (AIT) for the management of insect venom allergy. To inform this process, we sought to assess the effectiveness, cost-effectiveness and safety of AIT in the management of insect venom allergy. We undertook a systematic review, which involved searching 15 international biomedical databases for published and unpublished evidence. Studies were independently screened and critically appraised using established instruments. Data were descriptively summarized and, where possible, meta-analysed. Our searches identified a total of 16 950 potentially eligible studies; of which, 17 satisfied our inclusion criteria. The available evidence was limited both in volume and in quality, but suggested that venom immunotherapy (VIT) could substantially reduce the risk of subsequent severe systemic sting reactions (OR = 0.08, 95% CI 0.03-0.26); meta-analysis showed that it also improved disease-specific quality of life (risk difference = 1.41, 95% CI 1.04-1.79). Adverse effects were experienced in both the build-up and maintenance phases, but most were mild with no fatalities being reported. The very limited evidence found on modelling cost-effectiveness suggested that VIT was likely to be cost-effective in those at high risk of repeated systemic sting reactions and/or impaired quality of life. The limited available evidence suggested that VIT is effective in reducing severe subsequent systemic sting reactions and in improving disease-specific quality of life. VIT proved to be safe and no fatalities were recorded in the studies included in this review. The cost-effectiveness of VIT needs to be established. © 2016 The Authors.

    To determine the degree of conversion (DC) and Knoop microhardness (KHN) of resin-based composites (RBCs) containing trimethylbenzoyl-diphenylphosphine oxide (TPO) cured by polywave or monowave LED light-curing units (LCUs). Three groups (each n = 5) of Tetric EvoCeram (Ivoclar Vivadent), Vit-l-escence (Ultradent) and Herculite XRV Ultra (Kerr) were prepared in Teflon moulds (5mm in diameter and 2mm thick) and cured with polywave Bluephase(®) G2 (Ivoclar Vivadent), polywave Valo (Ultradent) or monowave Bluephase(®) (Ivoclar Vivadent; control) resulting in 9 groups. DC and KHN were determined using micro-Raman spectroscopy and Knoop microhardness, respectively. High-performance liquid chromatography and nuclear magnetic resonance spectroscopy were used to confirm the presence or absence of TPO in the three uncured materials. Data were statistically analysed using two-way and one-way ANOVA and DC and KHN were correlated using Pearson's correlation (α = 0.05). TPO was confirmed in Tetric EvoCeram and Vit-l-escence but not in Herculite XRV Ultra. All three LCUs produced comparable KHN for Tetric EvoCeram and Herculite XRV Ultra (p > 0.05). Both polywave LCUs resulted in significantly higher KHN for Vit-l-escence and higher DC in Tetric EvoCeram and Vit-l-escence than the monowave Bluephase(®) (p TPO-containing RBCs, but not in Herculite XRV Ultra. DC and KHN were linearly correlated in all three RBCs. Vit-l-escence showed the highest DC and KHN of the three materials tested. The use of polywave LEDs significantly improves both the DC and KHN of materials which contain TPO. This should be taken into account when curing bleached shades of RBCs even if the manufacturers do not indicate the presence of TPO in their materials. Copyright © 2012 Elsevier Ltd.

    The concept that the consumption of a diet rich in flavonoids can be associated with a reduced risk for cardiovascular disease is becoming increasingly accepted. In the present study we investigated the effects of the following four diets on blood pressure and cholesterol ester levels in hypercholesterolemic Golden Syrian hamsters: a high-fat, high-cholesterol diet (HFHC); a HFHC with 2% cranberry concentrate powder (HFHC+CE); a HFHC with 0.1% rutin (HFHC+Rutin); and a HFHC with 30 mg/kg vitamin E (HFHC+Vit.E). Diets were fed for either 12 or 20 weeks. Over the experimental period, heart rate and blood pressure measurements increased in the animals fed HFHC and HFHC+Vit.E; in contrast, these measurements were not increased in the animals fed HFHC+CE and HFHC+Rutin. Mesenteric and total abdominal fat were significantly lower in the animals fed HFHC+Rutin than in animals fed the other three diets. Ratios of plasma high-density lipoprotein cholesterol (HDL-C) to very-low-density lipoprotein cholesterol and of plasma HDL-C to low-density lipoprotein cholesterol were significantly higher in animals consuming HFHC+Vit.E than in animals fed the other three diets. Aortic cholesteryl ester levels were significantly lower in animals fed HFHC+CE, HFHC+Rutin, and HFHC+Vit.E at 20 weeks than in the animals fed HFHC. Fasting blood glucose concentrations were significantly lower in animals fed HFHC+Rutin and HFHC+Vit.E, and glucose clearance rates improved in animals fed HFHC+Rutin compared to animals fed the other three diets. Results obtained from this study support the concept that the chronic consumption of a flavonoid-rich diet can be beneficial with respect to cardiovascular health.

    In patients with a history of anaphylactic sting reactions, in-vitro tests are performed in order to demonstrate venom sensitization to the causative venom. Measurement of specific IgE-antibodies (sIgE) to the natural composite venom represents the standard in-vitro method to demonstrate venom sensitization. If sensitization to the composite venom cannot be demonstrated, one may determine sIgE to recombinant allergen compounds, in order to demonstrate sensitization to molecular venom allergens. Moreover, several cellular tests are available to confirm venom sensitization. Herein basophils, which carry cell-bound sIgE, can be used to produce a confirmatory response upon incubation with venom allergens. Reactions to both honey bee and vespid venom may either indicate true double sensitization or cross sensitization. The identification of antibodies cross-reacting to venoms and to other allergen sources does not exclude clinical relevance. Elevated baseline serum tryptase is a risk factor for severe systemic reactions after a field sting and during venom immunotherapy (VIT), the latter in particular for VIT with vespid venom. Serum tryptase measurement should, therefore, be included into routine diagnostics of venom allergy. The measurement of IgG-antibodies specific to venom is not recommended for routine work-up. None of the mentioned in-vitro tests, which may be used before, during or after VIT, allow, however, a precise prognosis with respect to future sting reactions, or to side effects and to the efficacy of VIT, respectively. To validate the reason for a VIT, one should also consider patient history and results of other tests.

    Venom immunotherapy (VIT) is the only effective treatment for hymenoptera hypersensitivity, but conventional protocols require a few weeks. We present the safety of a 3-day "rush" protocol that requires only 7 injections and 255 mgr cumulative dose before the 100 microg maintenance dose. Forty-nine patients (33 males, 16 females) of mean age 43.57+/-12.9 yrs received "rush" VIT. Only 7 injections were required until the maintenance dose of 100 mgr was reached on Day 5. On Day 1, four injections were administered with initial dose of 5 mgr and total dose of 75 microg. On Day 3 a cumulative dose of 180 mgr was administered in three injections (40 mgr, 60 mgr and 80 mgr). A dose of 100 mgr was administered on Day 5. Twenty-nine individuals were treated with Honey-Bee venom; 18 with Common wasp; 5 with Paper Wasp; while 13 patients received Mixed Vespid preparation. Inclusion criteria were documented IgE-mediated allergy with intradermal sensitivity to venom concentration and concomitant detection of specific venom IgE > or =0.35 kU/l. All patients reached the maintenance dose. Forty-nine patients received 65 immunotherapy courses, resulting in 1520 injections. Thirty-three systemic reactions: 7 during building phase (1.5%); and 26 in the maintenance dose (2.4%) were observed in 9 patients. The percentage of reactions/total injection number was 2.2%; all reactions were mild-to-moderate. Fourteen patients reported documented field stings at least two months after VIT onset with only one reported mild systemic reaction. We propose a simple "rush" VIT protocol in an outpatient setting as an easy-to-perform alternative option for VIT induction phase. Copyright 2009 SEICAP. Published by Elsevier Espana.

    Full Text Available This study was aimed to examine the protective effects of supplementation with calcium + zinc (Ca + Zn or vitamin E (Vit-E on Cd-induced renal oxidative damage. Young albino Wistar rats (180 ± 10 g (n = 6 control rats, Cd, Cd + Ca + Zn, and Cd + Vit-E experimental groups and the experimental period was 30 days. Rats were exposed to Cd (20 mg/kg body weight alone treated as Cd treated group and the absence or presence of Ca + Zn (2 mg/kg each or Vit-E (20 mg/kg body weight supplementation treated as two separate groups. The activities of the stress marker enzymes superoxide dismutase (SOD, catalase (CAT, glutathione reductase (GR, glutathione peroxidase (GPx, glutathione-S-transferase (GST and lipid peroxidase (LPx were determined in renal mitochondrial fractions of experimental rats. We observed quantitative changes in SOD isoenzymatic patterns by non-denaturing PAGE analysis, and quantified band densities. These results showed that Cd exposure leads to decreases in SOD, CAT, GR, and GPx activities and a concomitant increase in LPx and GST activities. Ca + Zn and Vit-E administration with Cd significantly reversed Cd-induced perturbations in oxidative stress marker enzymes. However, Vit-E showed more inhibitory activity against Cd than did Ca + Zn, and it protected against Cd-induced nephrotoxicity.

    Full Text Available Considering that the involvement of reactive oxygen species (ROS has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight on mice (25–30 mg treated with diazinon (32.5 or 16.25 mg/kg body weight organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT, aspartate aminotaransferase (AST, alkaline phosphatise (ALP, and some parameters of kidney function (urea and creatinine in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examined for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb, red blood cell (RBC and hematocrit (Hct in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN-treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function [Current Zoology 55(3:219–226, 2009].

    Given its elevated content of carotenoids, alfalfa protein concentrates (APC) have the potential to prevent oxidation of milk enriched in polyunsaturated fatty acids. The effects of feeding APC or supplemental vitamin E on production, composition, and oxidative stability of milk enriched in polyunsaturated fatty acids were evaluated using 6 lactating Holstein cows (224±18d in milk) in a replicated 3×3 Latin square (21-d periods, 14d for adaptation). Treatment diets contained (dry matter basis) (1) 9% soybean meal (control, CTL); (2) 9% soybean meal + 300 IU of vitamin E/kg (VitE treatment); or (3) 9% APC (APC treatment). Cows received a continuous abomasal infusion of 450g/d of linseed oil. As a result, milk fat content of cis-9,cis-12 18:2 increased from 1.08±0.13 to 3.9±0.40% (mean ± SD), whereas cis-9,cis-12,cis-15 18:3 increased from 0.40±0.04 to 14.27±1.81% during the experimental period compared with the pretrial period. Milk yield tended to be higher for APC (14.7kg/d) compared with CTL (13.4kg/d), and was greater than that for VitE (13.0kg/d). Protein yield was higher in cows fed APC (518g/d) compared with VitE (445g/d) but was not different from that in cows fed CTL (483g/d). These effects resulted in improved milk N efficiency in cows fed APC (26.1% of N intake secreted in milk) compared with CTL (23.0%) and VitE (22.9%). Feeding APC increased milk fat content of lutein (252μg/g) compared with CTL (204μg/g) and VitE (190μg/g). Milk fat content of vitamin E was higher for APC (34.5μg/g) compared with CTL (19.0μg/g) and tended to be lower than that with VitE (44.9μg/g). Redox potential of fresh milk from cows fed APC (152mV) was similar to that of VitE (144mV), but lower than that of CTL (189mV). Treatments had no effect on fresh milk contents of dissolved oxygen (8.1±1.5mg/L), and conjugated diene hydroperoxides (2.7±0.5mmol/L). The concentrations of volatile lipid oxidation products (propanal, hexanal, hept-cis-4-enal, 1-octen-3-one) tended

    The leading cause of vocal fold lesions such as nodules and polyps is phonotrauma, which causes microhematoma formation in the vocal fold cover that can initiate an inflammatory process. Vitamin A (Vit A) is essential for immunity, cellular differentiation and maintenance of respiratory epithelium. The aim of this study is to investigate the effect of Vit A (retinyl palmitate) on healing of vocal fold lesions, including vocal polyps and nodules. Eighteen patients with vocal fold lesions were included in the study. Of the patients, 13 had vocal polyps and 5 had vocal nodules. Patients received 90,000 IU oral Vit A in palmitate form daily for 2 months. In addition to Vit A treatment, only vocal hygiene recommendations were given to the patients, without any other medication or specific voice therapy. Pre- and post-treatment acoustic analysis [jitter % (jitt %), shimmer % (shim %), normalized noise energy (NNE), maximum phonation time (MPT), etc.] were performed. Lesion dimensions and stroboscopic findings were evaluated. Voice handicap index (VHI) was applied. Statistical analysis was performed between pre- and post-treatment measurements. Of the 18 patients, 8 had immature lesions (6 polyp-like lesions and 2 immature nodules) and 10 had mature lesion (7 polyps and 3 nodules). None of the patients showed complete healing. Partial response was seen in four patients with immature lesions. There were minimal changes in lesion dimensions, but this difference did not reach statistical significance. MPT of patients with immature lesions were close to significance level but overall MPT revealed no significant improvement (p = 0.051). Jitt %, shim % and NNE did not change significantly. In this study, the only statistically significant finding was VHI of the patients with immature lesions. Three of the patients complained of weight gain. Our data showed that Vit A at a given level of dose and duration seems to be ineffective in the treatment of benign vocal fold lesions. On

    Aseptic loosening, the most common indication for revision surgery in total hip arthroplasty, can result from osteolysis caused by polyethylene (PE) wear particles. PE wear is increased by age-related oxidation of PE and free radicals emerging during irradiation cross-linking. Diffusion of vitamin E into PE stabilizes free radicals to maintain the biomechanical properties of PE. The purpose of this study was to determine whether vitamin E-infused highly cross-linked PE cups could reduce wear rates. We performed a prospective randomized controlled trial, in which 62 patients were allocated to 2 groups: a study group that received a vitamin E-infused highly cross-linked PE (HXLPE/VitE) cup and a control group that received an ultra-high molecular weight PE (UHMWPE) cup. Using radiostereometric analysis, we measured the penetration of the femoral head into the cup 7 days after surgery (baseline) and then again at 6 months and at 1, 2, and 3 years later. Baseline variables did not differ significantly between the groups. At 1, 2, and 3 years after surgery, the HXLPE/VitE cup showed significantly less cumulative penetration (creep and wear) than the UHMWPE cup (p = 0.004, p < 0.0001, and p < 0.0001, respectively). The cumulative penetration after 3 years was 0.200 mm for the HXLPE/VitE cup versus 0.317 mm for the UHMWPE cup (p < 0.0001). From 1 to 3 years after surgery, after creep had stabilized and further penetration was mainly due to wear, the mean penetration increased only 0.04 mm in the HXLPE/VitE cup and 0.116 mm in the UHMWPE cup. Our results confirm that wear rates over the first 3 years following surgery were lower in HXLPE/VitE cups than in UHMWPE cups. This suggests that HXLPE/VitE cups may prevent osteolysis, implant loosening, and eventually revision surgery. Long-term follow-up data continue to be collected to confirm these findings.

    Hypothyroidism has a variety of adverse effects on cognitive function. The treatment of levothyroxine alone cannot restore cognitive defects of hypothyroid patients. Antioxidant vitamin E supplementation could be useful in disturbances which are associated with oxidative stress and could effectively slow the progression of Alzheimer disease. Thus, the purpose of this study was to evaluate oxidative stress status of the serum and hippocampus in hypothyroidism and to examine the effects of levothyroxine replacement therapy with vitamin E supplementation on cognitive deficit. Sprague-Dawley rats were randomly divided into five groups: control group, PTU group, PTU + Vit E group, PTU + L-T4 group, and PTU + L-T4 + Vit E group. Serum and hippocampus malondialdehyde (MDA) levels were determined using the thiobarbituric-acid reactive substances method. Serum and hippocampus superoxide dismutase (SOD) levels were determined by measuring its ability to inhibit the photoreduction of nitroblue tetrazolium. Learning and memory was assessed by Morris water maze test. In the present study, we found that the rats of PTU + Vit E group spent less time to find the platform on days 2, 3, 4, and 5 than the PTU group. Moreover, the rats of PTU + L-T4 + Vit E group spent less time to find the platform on days 4 and 5 than the PTU + L-T4 group. The time spent in the target quadrants was measured in the probe test and no difference was observed in all groups. Oxidative damage has been observed in the serum and hippocampus of hypothyroidism rat. SOD levels of serum and hippocampus tissue were significantly increased and MDA levels were significantly decreased in the PTU + Vit E and PTU + L-T4 + Vit E groups than the PTU and PTU + L-T4 groups. Therefore, these findings indicate that levothyroxine replacement therapy with vitamin E supplementation may ameliorate cognitive deficit in PTU-induced hypothyroidism through the decrease of oxidative stress status.

    Full Text Available Abstract Background In oviparous vertebrates, including fish, vitellogenesis consists of highly regulated pathways involving 17β-estradiol (E2. Previous studies focused on a relatively small number of hepatic expressed genes during vitellogenesis. This study aims to identify hepatic genes involved in vitellogenesis and regulated by E2, by using zebrafish microarray gene expression profiling, and to provide information on functional distinctive genes expressed in the liver of a vitellogenic female, using zebrafish as a model fish. Results Genes associated with vitellogenesis were revealed by the following paired t-tests (SAM comparisons: a two-month old vitellogenic (Vit2 females were compared with non-vitellogenic (NV females, showing 825 differentially expressed transcripts during early stages of vitellogenesis, b four-month old vitellogenic (Vit4 females were compared with NV females, showing 1,046 differentially expressed transcripts during vitellogenesis and c E2-treated males were compared with control males, showing 1,828 differentially expressed transcripts regulated by E2. A Venn diagram revealed 822 common transcripts in the three groups, indicating that these transcripts were involved in vitellogenesis and putatively regulated by E2. In addition, 431 transcripts were differentially expressed in Vit2 and Vit4 females but not in E2-treated males, indicating that they were putatively not up-regulated by E2. Correspondence analysis showed high similarity in expression profiles of Vit2 with Vit4 and of NV females with control males. The E2-treated males differed from the other groups. The repertoire of genes putatively regulated by E2 in vitellogenic females included genes associated with protein synthesis and reproduction. Genes associated with the immune system processes and biological adhesion, were among the genes that were putatively not regulated by E2. E2-treated males expressed a large array of transcripts that were not associated

    The present study was carried out to obtain an experimental model of vitamin D (vit D) insufficiency and established osteopenia (experiment 1) to then investigate whether vit D status, i.e. normal or insufficient, interferes with bone mass recovery resulting from bisphosphonate therapy (experiment 2). Rats (n = 40) underwent OVX (n = 32) or a sham operation (n = 8). The first 15 days post-surgery, all groups were kept under fluorescent tube lighting and fed a diet containing 200 IU% vit D (+D). They were then assigned during an additional 45 days to receive either +D or a diet lacking vit D (-D) and kept under 12 h light/dark cycles using fluorescent or red lighting. Serum 25HOD was significantly lower in -D rats (P < 0.0001). The type of lighting did not induce differences in 25OHD, calcium (sCa), phosphorus (sP), bone alkaline phosphatase (b-AL), CTX, bone density or histology. No osteoid was observed in undecalcified bone sections. Experiment 2 (105 days): rats were fed either +D or -D according to experiment 1 and were treated with either placebo or 16 mug olpadronate (OPD)/100 g rat/week during the last 45 days. Whereas 25HOD was significantly lower (P < 0.0001) in -D/OPD than in +D/OPD rats, no significant differences in sCa, sP, b-AL or CTX were observed. OPD prevented the loss of lumbar spine (LS) and proximal tibia (PT) BMD and the decrease in bone volume (BV/TV) (P < 0.05) and in the number of trabeculae observed in untreated rats. However, +D/OPD animals presented significantly higher values of LS BMD, PT BMD and BV/TV than -D/OPD rats (P < 0.05). No osteoid was observed in undecalcified sections of bone. In summary, this is the first experimental study to provide evidence that differences in vit D status may affect the anticatabolic response to bisphosphonate treatment. However, the molecular mechanism through which vit D insufficiency reduces the effect of the aminobisphosphonate remains to be defined.

    Full Text Available Abstract Background The biological mechanisms in the association between the metabolic syndrome (MS and various biomarkers, such as 25-hydroxyvitamin D (vit D and magnesium, are not fully understood. Several of the proposed predictors of MS are also possible predictors of parathyroid hormone (PTH. We aimed to explore whether PTH is a possible mediator between MS and various possible explanatory variables in morbidly obese patients. Methods Fasting serum levels of PTH, vit D and magnesium were assessed in a cross-sectional study of 1,017 consecutive morbidly obese patients (68% women. Dependencies between MS and a total of seven possible explanatory variables as suggested in the literature, including PTH, vit D and magnesium, were specified in a path diagram, including both direct and indirect effects. Possible gender differences were also included. Effects were estimated using Bayesian path analysis, a multivariable regression technique, and expressed using standardized regression coefficients. Results Sixty-eight percent of the patients had MS. In addition to type 2 diabetes and age, both PTH and serum phosphate had significant direct effects on MS; 0.36 (95% Credibility Interval (CrI [0.15, 0.57] and 0.28 (95% CrI [0.10,0.47], respectively. However, due to significant gender differences, an increase in either PTH or phosphate corresponded to an increased OR for MS in women only. All proposed predictors of MS had significant direct effects on PTH, with vit D and phosphate the strongest; -0.27 (95% CrI [-0.33,-0.21] and -0.26 (95% CrI [-0.32,-0.20], respectively. Though neither vit D nor magnesium had significant direct effects on MS, for women they both affected MS indirectly, due to the strong direct effect of PTH on MS. For phosphate, the indirect effect on MS, mediated through serum calcium and PTH, had opposite sign than the direct effect, resulting in the total effect on MS being somewhat attenuated compared to the direct effect only

    Vitamin D (VitD) is an anti-inflammatory hormone; however, some evidence shows that VitD may induce the expression of activation markers, such as CD38 and HLA-DR. We explored its effect on the expression of these markers on CD4+ and CD8+ T-cells in vitro, and their potential correlations in vivo. CD38 and HLA-DR expression was measured by flow cytometry in PHA/IL-2-activated mononuclear cells cultured under VitD precursors: three cholecalciferol (10-11M, 10-9M, 10-7M; n=11) and two calcidiol (40 ng/mL, 80 ng/mL; n=9) concentrations. The correlation between the expression of these markers in freshly isolated blood cells and serum levels of calcidiol was also explored (n=10). Cholecalciferol at 10-7M increased the proportion of CD4+ CD38+ and CD8+ CD38+ cells, and decreased CD8+HLA-DR+ cells. As co-expression, it increased the CD38+HLA-DR- and decreased CD38-HLA-DR+ subpopulations in both CD4+ and CD8+ T-cells, and decreased CD4+CD38-HLA-DR- and CD8+ CD38+HLA-DR+; whereas both calcidiol concentrations decreased the proliferation of CD38-HLA-DR- and CD38-HLA-DR+ subpopulations. Both forms of VitD increased the number of CD38 molecules per cell. In contrast, there was a positive but non-significant correlation between serum calcidiol levels and the expression of CD38 and HLA-DR in CD4+ and CD8+ T-cells. Although no significant correlations were observed in vivo in healthy subjects, VitD treatment in vitro modulated immune activation by increasing the expression of CD38 and decreasing the proliferation of HLA-DR+ and resting cells, which may correlate with improved effector and decreased proliferative capabilities. These results highlight the potential use of VitD as therapeutic strategy in immune disorders.

    Successful venom immunotherapy (VIT) in Hymenoptera allergy is usually associated with a strong increase in venom-specific serum IgG antibodies (sIgG). We evaluated a new commercial test for the assay of sIgG (Pharmacia CAP Systemtrade mark IgG RAST(R) FEIA; FEIA), in comparison with a conventional ELISA technique. Sera from 40 bee- and 40 Vespula-allergic patients were analyzed by FEIA and ELISA before and 3 months after starting VIT. The correlation between sIgG obtained with the two methods was significant: r = 0.862, pRAST FEIA is a reproducible and sensitive method for the assay of venom-specific sIgG.

    Hypertension is considered as the most common risk factor for cardiovascular diseases, also is regarded as a leading cause of the mortality and morbidity worldwide. The mechanisms underlying the pathological process of hypertension are not completely explained. However, there is growing evidence that increased oxidative stress plays an important role in the pathophysiology of hypertension. Several preclinical studies and clinical trials have indicated that antioxidant therapy is important for management of hypertension, using antioxidants compounds such as alpha tocopherol (Vit E) and ascorbic acid (Vit C), polyphenols with others and some antihypertensive drugs that are now in clinical use (e.g. ACEIs, ARBs, novel B-blockers, dihydropyridine CCBs) which have antioxidative pleiotropic effects.
