Temporal variations of dietary habits in a high-risk area for upper gastrointestinal cancers: A population-based study from Northern Iran

Background: Nutrition transition is a global health problem, especially in developing countries. It is known as an important factor for development of different types of health conditions including cancers. Objectives: We aimed to assess the pattern of nutrition transition in a high-risk area for upper gastrointestinal cancers in Northern Iran during the last decade. Materials and Methods: This cross-sectional study was conducted on households of Golestan province, Iran. Data on household food consumption between 2001 and 2010 were obtained from the Statistical Center of Iran. The proportions of households with medium/high consumption of main foods were calculated for each year. Joint point software was used for assessing trends. Annual percent changes (APCs) and 95CIs were calculated. Results: In total, 12,060 households were recruited. The APCs (95CI) of the proportion of households medium/high consumption of cereals, vegetables, legumes, fish, dairy products and meats were -3.1 (-4.1 to -2.2), -2.9 (-3.8 to -2.1), -2.3 (-3.2 to -1.4), -2.8 (-3.3 to -2.4), -1.9 (-3.0 to -0.9) and 2.7 (1.2 to 4.3), respectively. Conclusions: We found significant increase in meat consumption among our population between 2001 and 2010. Our results also suggested significant decreasing trend in consumption of so-called healthy foods including, plant foods, fish, and dairy products. Regarding its correlation with health conditions including cancers, nutrition transition should be considered as a priority in health policy making in our region as well as other high-risk populations. It is recommended to conduct community level interventions to increase consumption of plant foods, fish, and dairy products

Acceptance and commitment therapy as an adjunct to the MOVE! programme: a randomized controlled trial.

ObjectiveThe current study tested the efficacy of an acceptance and commitment therapy (ACT) group intervention for disinhibited eating behaviour as an adjunct to the Veterans Affairs MOVE!© weight management programme.MethodsVeterans (N = 88) with overweight or obesity who completed the MOVE! weight management programme and self-identified as having problems with 'stress-related eating' were randomized to four 2-h weekly ACT sessions or a continued behavioural weight-loss (BWL) intervention. Assessments were completed at baseline, post-treatment and 3- and 6-month follow-up on outcomes of interest including measures of disinhibited eating patterns, obesity-related quality of life, weight-related experiential avoidance and weight.ResultsThe BWL group exhibited significantly greater reductions in binge eating behaviour at post-treatment compared with the ACT group. Significant improvements in other outcomes were found with minimal differences between groups. In both groups, decreases in weight-related experiential avoidance were related to improvements in binge eating behaviour.ConclusionsTaken together, the continued BWL intervention resulted in larger improvements in binge eating behaviour than the ACT intervention. The two groups showed similar improvements in other disinhibited eating outcomes. Future studies are encouraged to determine if more integrated or longer duration of ACT treatment may maximize eating outcomes in MOVE.Trial Registration Number: This trial was registered with ClinicalTrials.gov database (NCT01757847)

Aflatoxin contamination of wheat flour and the risk of esophageal cancer in a high risk area in Iran

Background: Golestan province in northeastern Iran has been known as a high-risk area for esophageal cancer (EC). This study was conducted to assess aflatoxin (AF) contamination of wheat flour (WF) samples in high and low EC-risk areas of Golestan province. Methods: Four WF samples were collected randomly from each of 25 active silos throughout the province in 2009. The levels of AFs were measured using the High-performance liquid chromatography method. Using the data of EC rates obtained from Golestan population-based cancer registry, the province was divided into high and low risk areas for EC. Student t-test and multivariate regression analysis were used to compare the levels of aflatoxins as well as the condition of silos between the two areas. Results: One hundred WF samples were collected. The mean levels of total aflatoxin and aflatoxin B1 was 1.99 and 0.53ngg-1, respectively. The levels of total AF (p=0.03), AFG2 (p=0.02) and AFB1 (p=0.003) were significantly higher in samples obtained from high risk area. Multivariate regression analysis showed that humidity of silo was the most important source of difference between silos of the two areas (p=0.04). Conclusion: We found a positive relationship between AF level of WF samples and the risk of EC. So, AF contamination may be a possible risk factor for EC in our region. We also found that humidity of silos was the most important determinant of AF contamination of WF. Intensive control of silos conditions including humidity and temperature are needed especially in high EC-risk areas. © 2013 Elsevier Ltd

Development of some New Micronutrient Rich Blends of Edible Vegeteble Oils

Fats and oils in the form of edible vegetable oils are integral to our diets, and comprises of an important source of calorie density in human diet. Besides, the edible vegetable oils have nutritional value and health benefits due to the presence of essential fatty acids and many micronutrients as unsaponifiable matter. The unsaponifiable matter of vegetable oils includes micronutrients such as tocopherols, tocotrienols, b-carotene, oryzanol, squalene etc, which have been reported for health benefits

Vegetable Oil Blends after Frying and Sample Stored in Different Storage Packs

The work done in the reporting quarter concerns the micronutrient analysis of the blend in fresh oil samples and in samples stored under different storage conditions in various types of containers and as well as before and after frying. Conjugated dienes, p-anisidine value, specific gravity, copper and iron content of the oil samples under different conditions were also estimated, and the oxidative stability of the oils was determined. In particular the retention pattern of micronutrients, conjugated dienes and p-anisidine values in the blend under various storage conditions in different packs was studied

Fabrication of Pd NPs on pectin-modified Fe3O4 NPs: A magnetically retrievable nanocatalyst for efficient C-C and C-N cross coupling reactions and an investigation of its cardiovascular protective effects

The present report represents the synthesis of a novel Pd NPs immobilized over a natural polysaccharide (pectin) coated Fe3O4 magnetic nanocomposite material (Fe3O4@pectin/Pd) for investigating the cardiovascular protective effects. The biomolecular functionalization not only stabilizes the ferrite nanoparticles from agglomeration but also provides an environment for the biogenic reduction of Pd2+ ions. This protocol is a promising breakthrough for the synthesis of a quasi-heterogeneous catalyst, a bridge between heterogeneous and homogeneous medium. The structure, morphology and physicochemical properties of the material were characterized utilizing various analytical techniques like FT-IR FE-SEM, TEM, VSM, EDX-elemental mapping, ICP, EDX and XPS. The catalyst showed excellent reactivity in C-C and C-N cross coupling reactions via Suzuki and Buchwald-Hartwig reactions respectively. An array of different biphenyls and aryl amines were then procured by reactions of various aryl halides with phenyl boronic acid or secondary amines over the catalyst affording good to excellent yields. The catalyst was easily recoverable using an external magnet and thereafter recycled for several trials with insignificant palladium leaching or loss in catalytic performance. To investigate the cardiovascular protective activities of catalyst, the MTT assay was done on Human Aortic Endothelial Cells (HAEC), Human Coronary Artery Endothelial Cells (HCAEC), and Human Pulmonary Artery Endothelial Cells (HPAEC) cell lines. Nanocatalyst-treated cell cutlers significantly (p <= 0.01) decreased the caspase-3 activity, and DNA fragmentation. It raised the cell viability and mitochondrial membrane potential in the high concentration of Mitoxantrone-treated HAEC, HCAEC, and HPAEC cells. According to the above findings, nanocatalyst can be administrated as a cardiovascular protective drug for the treatment of cardiovascular diseases after approving in the clinical trial studies in humans.

Static and vibration analysis of functionally graded beams using refined shear deformation theory

Static and vibration analysis of functionally graded beams using refined shear deformation theory is presented. The developed theory, which does not require shear correction factor, accounts for shear deformation effect and coupling coming from the material anisotropy. Governing equations of motion are derived from the Hamilton's principle. The resulting coupling is referred to as triply coupled axial-flexural response. A two-noded Hermite-cubic element with five degree-of-freedom per node is developed to solve the problem. Numerical results are obtained for functionally graded beams with simply-supported, cantilever-free and clamped-clamped boundary conditions to investigate effects of the power-law exponent and modulus ratio on the displacements, natural frequencies and corresponding mode shapes

Design against distortion for aerospace-grade additively manufactured parts - PADICTON

Collections: Brunel Composite CentreAdditive manufacturing (AM) is a computer-controlled 3D printing process with increasing demand in the aerospace sector. This manufacturing process offers the production of lighter components, design flexibility, reduced labour effort and material cost, as well as decreased waste generation compared with subtractive manufacturing. Additionally, AM can provide parts availability at the point of use, significantly improving the supply chain. However, producing advanced high-temperature AM thermoplastic components remains a challenging task as these require a high-temperature build chamber environment that is prone to producing parts with thermal stresses and warpage. PADICTON project aims to develop a tool capable of accurately and rapidly predicting and correcting such distortions, offering improved quality of the produced parts and minimising rejection rates. Creating this tool requires conducting a comprehensive mechanical and thermal characterisation campaign to optimise the print parameters and part geometry. In this study, the concept of the project and the findings of the initial mechanical and optical characterisation tests for two AM processes, namely fused deposition modelling and selective laser sintering, are presented and discussed.The authors would like to acknowledge the PADICTON partners, namely FDM Digital Solutions, e Xstream Engineering, part of Hexagon Manufacturing Intelligence, AMendate, as well as the Topic Manager of the project, Airbus, for their assistance and encouragement towards the realisation of the activities. In addition, the consortium would like to express its gratitude to EOS for their technical support. Furthermore, the activities of PADICTON project have received funding from the Clean Sky 2 Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement number 86481

Alterations in early auditory evoked potentials and brainstem transmission time associated with tinnitus residual inhibition induced by auditory electrical stimulation

Introduction: Residual inhibition (RI) is the temporary inhibition of tinnitus by use of masking stimuli when the device is turned off. Objective: The main aim of this study was to evaluate the effects of RI induced by auditory electrical stimulation (AES) in the primary auditory pathways using early auditory-evoked potentials (AEPs) in subjective idiopathic tinnitus (SIT) subjects. Materials and Methods: A randomized placebo-controlled study was conducted on forty-four tinnitus subjects. All enrolled subjects based on the responses to AES, were divided into two groups of RI and Non-RI (NRI). The results of the electrocochleography (ECochG), auditory brain stem response (ABR) and brain stem transmission time (BTT) were determined and compared pre- and post-AES in the studied groups. Results: The mean differences in the compound action potential (CAP) amplitudes and III/V and I/V amplitude ratios were significantly different between the RI, NRI and PES controls. BTT was significantly decreased associated with RI. Conclusion: The observed changes in AEP associated with RI suggested some peripheral and central auditory alterations. Synchronized discharges of the auditory nerve fibers and inhibition of the abnormal activity of the cochlear nerve by AES may play important roles associated with RI. Further comprehensive studies are required to determine the mechanisms of RI more precisely
