A new Equation of State (EOS) for Lithium 6 Deuteride (⁶LiD) was created, sesame 7363. This EOS was released to the user community under “eos-developmental” as sesame 97363. The construction of this new EOS is a modification of a previously released EOS, sesame 7360¹. Sesame 7360 is too stiff (5-10% excess pressure) at high compressions and high temperatures (ρ = 4-110g/cm³, T = 30-10,000 eV) compared to orbital-free density-functional theory. Sesame 7363 is softer and gives a better representation of the physics over this range without compromising the agreement with the experimental and simulation data that sesame 7360 was based on.

Introduction of sesame germplasm from Myanmar and Mexico was not satisfactory for successful development of the Australian sesame industry. Therefore, a national breeding programme was undertaken by CSIRO and the Northern Territory Department of Primary Industry and Fisheries (NTDPIF). The main traits considered for selection were latitudinal adaptation, temperature response, growth habit, determinacy, palatability, capsules per leaf axil, seed shattering and seed dormancy. The CSIRO breeding efforts started in 1989 with a hybridization programme using germplasm from Japan, Mexico, Myanmar, Rep. of Korea and Venezuela. This programme resulted in selection in the F 6 generation of branched types released under the names 'Beech's choice' and 'Aussie Gold'. The NTDPIF sesame breeding programme started in 1993 with hybridization of introductions. The Mexican cultivar 'Yori 77' was selected for release, and after several years of intraline selection the uniculm cultivar 'Edith' was released in 1996. Further breeding continues to improve seed retention and resistance to charcoal rot. (author)

Two field experiments were conducted at the Experimental Farm of Faculty of Agriculture, Suez Canal University at Ismailia during 2008 and 2009 seasons to study the effect of nitrogen fertilization and planting density on growth , yield, its attributes as well as seed quality of new sesame variety (Taka 2 cv.). On newly reclaimed sandy soils of Ismailia Governorate, Egypt, experimental design in split plots form with four replications was used. Four levels of nitrogen fertilization 55, 105, 155 and 205 Kg/ha were arranged randomly in the main plots and three planting distances between hills (10, 15 and 20 cm, respectively) were distributed at random in the sub plots. Increasing N fertilizer level up to 205 Kg/ha significantly increased plant height, fruiting zone length, height of the first fruiting branch, number of branches and capsules/plant, 1000-seed weight, seed weight/plant, seed oil content (%) and seed and oil yields /ha. Decreasing planting distance from 20 to 15 and 10 cm consistently and significantly increased plant height, height of the first fruiting branch and seed and oil yields /ha. The reverse was true regarding the yield components. These results were expected, since experiment soil was newly reclaimed sandy soil and very poor in the nutrients and organic matter. (author)

Epiphytotic conditions and non-availability of resistant germplasm prompted the use of mutation induction technique to develop a variety resistant to phytophthora blight caused by Phytophthora nicotianae var. parasitica in sesame (Sesamum indicum L.). Dry seeds of three varieties were irradiated with six doses of Co-60 gamma rays in the range 100-700 Gy. The mutant line 182/3 of variety MI 3 selected from 200 Gy dose treatment in the M2 showed tolerance to the disease at Angunakolapelessa in the disease nursery. The mutant line was tested in the advanced yield trial, National Co-ordinated Varietal Trials and in the National Coordinated Varietal Adaptability Trials. It was superior to MI 3 in yield and plant survival during the seasons favouring development of the disease and was similar to MI 3 and other recommended varieties during the other seasons. the variety has cream coloured seeds, branched stem, The mutant was released as ANK S2 in 1993 and may be used to increase the declining sesame area due to low yield of existing varieties and their susceptibility to disease. It should also serve as valuable parent material in cross-breeding programmes
Induced mutations in sesame breeding

Ashri, A.

2001-01-01

The scope of induced mutations in sesame (Sesamum indicum L.) breeding is reviewed. So far in Egypt, India, Iraq, Rep. of Korea, and Sri Lanka, 14 officially released varieties have been developed through induced mutations: 12 directly and 2 through cross breeding (one using the 'dt45' induced mutant from Israel). For another variety released in China there are no details. The induced mutations approach was adopted primarily in order to obtain genetic variability that was not available in the germplasm collection. The mutagens commonly applied have been gamma rays, EMS and sodium azide. Sesame seeds can withstand high mutagen doses, and there are genotypic differences in sensitivity between varieties. The mutants induced in the above named countries and others include better yield, improved seed retention, determinate habit, modified plant architecture and size, more uniform and shorter maturation period, earliness, resistance to diseases, genic male sterility, seed coat color, higher oil content and modified fatty acids composition. Some of the induced mutants have already given rise to improved varieties, the breeding value of other mutants is now being assessed and still others can serve as useful markers in genetic studies and breeding programmes.

Sesame (Sesamum indicum L.) is an ancient oil crop considered to be still at an early stage in breeding. The fact that sesame is a crop of mainly developing countries with limited available research funds for long term breeding programmes, resulted in very few breeding efforts in research stations. Furthermore, sesame is not a mandate crop of any of the international agriculture research centers. Until recently most of the released sesame varieties in countries such as China, India and the Republic of Korea were the product of selection and pedigree breeding. A major constraint in this approach was the lack of sufficient genetic variation within the existing germplasm collections, especially for traits such as resistance to various diseases and seed retention. This is where mutation techniques could offer a possible solution. The United Nations Food and Agriculture Organization (FAO) organized some expert consultations on sesame breeding between 1981 and 1987, which all recommended the use of mutation induction for the enhancement of genetic variability with a focus on the following traits: modified plant architecture, seed retention, and resistance to diseases and pests. As a result, most of these recommendations have been included in this five year co-ordinated research project (CRP) that started in 1993, organized by the Plant Breeding and Genetics Section of the Joint FAO/IAEA Division. This CRP focused on the induction of the above mentioned characters in different sesame improvement programmes, and on the enhancement of co-operation between sesame breeders in developed and developing countries. Each participant covered a number of traits important for their specific breeding needs. During regular meetings under this project the participants had the opportunity to jointly appraise and evaluate sesame mutants and varieties in demonstration fields, thus strengthening the mutual effort for the genetic improvement of sesame through mutation techniques.

Epiphytotic conditions and lack of resistant germplasm in sesame (Sesamum indicum L.) prompted the use of mutation induction techniques to develop a variety resistant to Phytophthora blight caused by Phytophthora nicotianae var. parasitica. Dry seeds of three varieties were irradiated with six doses of 60 Co gamma rays in the range 100-700 Gy. The mutant line 182/3 of variety MI-3 selected from 200 Gy dose treatment in M 2 showed tolerance to the disease in subsequent testing at Angunakolapelessa in the disease nursery. The mutant line was tested in the major yield trial, National Co-ordinated Variety Trials and in the National Co-ordinated Variety Adaptability Trials. It was superior to MI-3 in yield and plant survival during the seasons favouring development of the disease and was similar to MI-3 and other recommended varieties in other seasons. The mutant has cream colour seeds, branched stem, and recorded 1890 kg/ha at Girandurukotte, 1593 kg ha -1 at Maha Illuppallama and 1151 kg/ha at Angunakolapelessa under rainfed conditions. The mutant was released as ANK-S2 in 1993 and may be used to increase the declining sesame area due to low yield of existing varieties and their susceptibility to disease. It should serve as a valuable parent material in cross-breeding programmes too. (author)
Cross-Linking Mast Cell Specific Gangliosides Stimulates the Release of Newly Formed Lipid Mediators and Newly Synthesized Cytokines

Full Text Available Mast cells are immunoregulatory cells that participate in inflammatory processes. Cross-linking mast cell specific GD1b derived gangliosides by mAbAA4 results in partial activation of mast cells without the release of preformed mediators. The present study examines the release of newly formed and newly synthesized mediators following ganglioside cross-linking. Cross-linking the gangliosides with mAbAA4 released the newly formed lipid mediators, prostaglandins D2 and E2, without release of leukotrienes B4 and C4. The effect of cross-linking these gangliosides on the activation of enzymes in the arachidonate cascade was then investigated. Ganglioside cross-linking resulted in phosphorylation of cytosolic phospholipase A2 and increased expression of cyclooxygenase-2. Translocation of 5-lipoxygenase from the cytosol to the nucleus was not induced by ganglioside cross-linking. Cross-linking of GD1b derived gangliosides also resulted in the release of the newly synthesized mediators, interleukin-4, interleukin-6, and TNF-α. The effect of cross-linking the gangliosides on the MAP kinase pathway was then investigated. Cross-linking the gangliosides induced the phosphorylation of ERK1/2, JNK1/2, and p38 as well as activating both NFκB and NFAT in a Syk-dependent manner. Therefore, cross-linking the mast cell specific GD1b derived gangliosides results in the activation of signaling pathways that culminate with the release of newly formed and newly synthesized mediators.

The contents of sesamol and related lignans in sesame, tahina and halva as determined by a newly developed polarographic and stripping voltammetric analysis

Energy Technology Data Exchange (ETDEWEB)

Tokusoglu, O.; Kocak, S.; Aycan, S.

2009-07-01

The contents of antioxidant lignans (Sesamol) in sesame, commercial formulations of tahina and halva, which are processed tahina foods, were determined by Differential Pulse Polarography (DPP) with a capillary hanging mercury drop electrode (HMDE). A platinum wire was used as the counter electrode and Ag/AgCl was the reference electrode. Samples have been analyzed by standard addition procedures and found to be quantitative (p<0.01). Due to the fact that sesamol is an oil-soluble phenolic compound , it was found in the oil levels of sesame, tahina and halvas. Sesame samples contained 51.05-56.46 % in oil whereas tahina samples contained 52.12-53.79 % in oil. The oil percentage of plain halva was found to be 28.79 - 30.13 % (p<0.01). Phenolic lignans sesamol in sesame was 0.26-0.32 mg/100g oil, whereas the sesamol in tahina was 10.98-12.33 mg/100g oil. The sesamol in commercial plain halva samples and the open marketed plain halva samples contained 8.24-9.12 mg/100g oil and 4.97 mg sesamol /100g oil, respectively (R{sup 2}=0.9999) (p<0.01). The proposed Differential Pulse Polarographic (DPP) method is a rapid, reproducible procedure for the simultaneous determination of phenolic lignans in sesame and food products with sesame. It provides an adequate, sensitive, quantitative detection of these nutraceuticals in the commercial food industry. (Author) 26 refs.

2007-10-01

Full Text Available Background: Plant-origin foods are among the most important sources of food allergic reactions. An increase in the incidence of sesame seed allergy among children and adults has been reported in recent years. The aim of this preliminary study was to investigate the prevalence, importance and clinical manifestations of sesame allergy among Iranian patients.Methods: In a cross-sectional survey, 250 patients with suspected IgE-mediated food allergies completed a questionnaire and underwent skin prick tests with sesame extract as well as cross-reacting foods (walnut, soya and peanut. Total IgE and sesame-specific IgE levels were measured. Patients with positive skin test reactions and/or IgE specific for sesame without clinical symptoms were considered sensitive to sesame. The patients who also had clinical symptoms with sesame consumption were diagnosed as allergic to sesame.Results: Of the 250 patients enrolled in this study, 129 were male and 121 female, with a mean age of 11.7 years. The most common food allergens were cow's milk, egg, curry, tomato and sesame. Sesame sensitivity was found in 35 patients (14.1%. Only five patients (2% had sesame allergy. Sesame-sensitive patients had a significantly higher frequency of positive prick test to cross-reacting foods when compared to non-sensitized patients (p=0.00. The type of symptom was independent of gender and age of the patients, but urticaria and dermatitis-eczema were significantly more frequent in sensitized patients (p=0.008.Conclusions: This is the first study addressing the prevalence of sesame seed allergy in Iranian population. We found sesame to be a common and important cause of food allergy. The panel of foods recommended for use in diagnostic allergy tests should be adjusted.

It is a major cause of anaphylaxis in the Middle East and is the third most common food allergen in Israel. We conducted a systematic review of original articles published in the last 10 years regarding the diagnosis and management of sesame allergy. Skin prick testing appears to be a useful predictor of sesame allergy in infants, although data are less consistent in older children and adults. The diagnostic capacity of serum-specific immunoglobulin E is poor, especially in studies that used oral food challenges to confirm the diagnosis. Double-blind, placebo-controlled food challenge thus remains the diagnostic gold standard for sesame allergy. The cornerstone of sesame allergy management is allergen avoidance, though accidental exposures are common and patients must be prepared to treat the consequent reactions with epinephrine. Novel diagnostic and treatment options such as component-resolved diagnostics, basophil activation testing, and oral immunotherapy are under development but are not ready for mainstream clinical application.

UNESCO became the umbrella organization for SESAME at its Executive Board 164th session, May 2002. The following comments about SESAME were made by this board: ``a quintessential UNESCO project combining capacity building with vital peace-building through science'' and ``a model project for other regions.'' Now that SESAME is well underway, other regions (e.g.; Africa and Central Asia) should be made aware of this progress, and they should be welcomed to join SESAME as a first step in developing similar projects in their region. Students and scientists from other regions should be encouraged to attend SESAME Users' meeting, schools, workshops, etc. where they can learn about synchrotron radiation sources, beamlines, and science. They should be invited to join SESAME scientists in designing and commissioning accelerators and beamlines, gaining relevant experience for their own projects and helping SESAME in the process.

Antioxidant effect of flaxseed and sesame oil against radiotoxicity

International Nuclear Information System (INIS)

Manju Lata; Srivastav, P.; Patni, S.

2014-01-01

The use of radiation has become an integral part of modern life necessitates a safe and cost effective radioprotector. Common nutritional plants such as flaxseed and sesame are rich of lignin and may prove efficient antioxidants. The lignin like secoisolericiresinonal and pinoresinol found in flaxseed oil and sesame are reported to have strong antioxidant property. Cyclophosphamide induced in decline in the level of GSH, GSH-Px and alkaline phosphate was also significantly averted by flaxseed and sesame oil in mice blood. The high antioxidative properties of sesame appear to be related ligans, such as sesamol, sesamolinol. The mice have been administered with flaxseed oil and sesame oil for fifteen days, before an acute dose of radiation (5 Gy at a dose rate of 1.07 Gy/min). Both the herbs have been found to check the level of lipid peroxidation and protein degradation induces by radiation in mice brain. The survivability in terms of life span showed much better picture in sesame oil pretreated irradiated mice in comparison to linseed oil pretreated irradiated mice. Statistically analyzed survival data produced a dose reduction factor (DRF) equals to 1.41 for flaxseed oil and 1.45 for sesame oil. The result indicates that sesame oil provide a better protection in comparison to linseed oil. Since flaxseed and sesame oil have demonstrated excellent antioxidative effect against radiation, it would further pave way to the formulation of medicine against radiation and several radiomimetic drug induce toxicity.

Full Text Available Sesame is an important oilseed crop, which has been used as a traditional health food to ameliorate the prevention of various diseases. We evaluated the changes in the anti-allergic activities of sesame by bioconversion. SDS-PAGE of non-fermented sesame proteins showed major allergen bands, while that of fermented sesame showed only a few protein bands. Additionally, we investigated the effectiveness of fermented sesame by bioconversion in tumor necrosis factor-α (TNF-α- and interferon-γ (IFN-γ-induced HaCaT cells. In HaCaT cells, fermented sesame inhibited the mRNA expression of interleukin-6 (IL-6 and interleukin-1β (IL-1β, thymus and macrophage-derived chemokine (MDC/CCL22, activation-regulated chemokine (TARC/CCL17, and intercellular adhesion molecule-1 (ICAM-1. Moreover, fermented sesame inhibited the activation of nuclear factor-κB (NF-κB and signal transducer and activator of transcription 1 (STAT1. Fermented sesame exerts anti-allergic effects by suppressing the expression of chemokines and cytokines via blockade of NF-κB and STAT1 activation.

Although the importance of microsatellites markers or simple sequence repeats (SSR in crop genotyping, genetics, and breeding applications is well established, only a little information exist concerning SSRs at the whole genome level in sesame. In addition, SSRs represent a suitable marker type for sesame molecular breeding in developing countries where it is mainly grown. In this study, we identified 138,194 genome-wide SSRs of which 76.5% were physically mapped onto the 13 pseudo-chromosomes. Among these SSRs, up to three primers pairs were supplied for 101,930 SSRs and used to in silico amplify the reference genome together with two newly sequenced sesame accessions. A total of 79,957 SSRs (78% were polymorphic between the three genomes thereby suggesting their promising use in different genomics-assisted breeding applications. From these polymorphic SSRs, 23 were selected and validated to have high polymorphic potential in 48 sesame accessions from different growing areas of Africa. Furthermore, we have developed an online user-friendly database, SisatBase (http://www.sesame-bioinfo.org/SisatBase/, which provides free access to SSRs data as well as an integrated platform for functional analyses. Altogether, the reference SSR and SisatBase would serve as useful resources for genetic assessment, genomic studies, and breeding advancement in sesame, especially in developing countries.

Full Text Available Sesame oil is widely consumed as nutritious food, cooking oil, and in pharmaceuticals and food. In this study, the antinociceptive and anti-inflammatory properties of the sesame oil and sesamin were investigated. The sesame oil and sesamin reduced the number of abdominal contortions at the doses 100, 200, or 400 mg/kg. The first and second phases of the time paw licking were inhibited by sesame oil and sesamin (100, 200, or 400 mg/kg. After 90 min of treatment, sesame oil and sesamin increased the reaction time on a hot plate (200 or 400 mg/kg. Considering the tail-immersion assay, the sesame oil and sesamin produced significant effect after 60 min at the doses of 100, 200, or 400 mg/kg. After 4 h of application of the carrageenan, the sesame oil and sesamin were effective against the paw edema. The exudate volume and leucocyte migration were also reduced by sesame oil and sesamin. These results suggest that sesamin is one of the active compounds found in sesame oil and justify the antinociceptive and anti-inflammatory properties of this product.

The use of radiation has become an integral part of modern life. Interest has been generated to develop potential drug of plant origin for the modification of radiation toxicity. Common nutritional plants such as flaxseed and sesame are rich of lignan and may prove efficient antioxidants. The lignan like secoisolericiresinol and pinoresinol found in flaxseed and sesame are reported to have strong antioxidant nature. Cyclophosphamide induced decline in the level of GSH, GSH-Px and alkaline phosphatase was also significantly averted by flaxseed oil in mice blood. The high antioxidative properties of sesame appear to be related to lignans, such as sesamol, sesamolinol, pinoresinol, p1 and sesaminol. The mice have been administered with flaxseed oil and sesame oil for fifteen days, before an acute dose of radiation (5 Gy at a dose rate of 1.07 Gy/min). Both the herbs have been found to check the level of lipid peroxidation and protein degradation induced by radiation in mice brain. The survivability in terms of life span showed much better picture in sesame oil pretreated irradiated mice in comparison to linseed oil pretreated irradiated mice. Statistically analyzed survival data produced a dose reduction factor (DRF) = 1.41 for flaxseed oil and 1.45 for sesame oil. The results indicate that sesame oil provide a better protection in comparison to linseed oil. Since flaxseed and sesame oil have demonstrated excellent antioxidative effect against radiation, it would further pave way to the formulation of medicine against radiation and several radiomimetic drug induced toxicity

Recently, we found sesame to be a major cause of severe IgE-mediated food allergic reactions among infants and young children in Israel. The purpose of this study was to describe the different patterns of sesame sensitivity. We have identified three subgroups among our patients (n = 32). Group I (n = 23, M/F; 14/9) consisted of cases with IgE-mediated sesame allergy. The mean age of the first allergic reaction was 11.7 months. Although the main clinical manifestation was urticaria/angiedema (n = 14, 60%), anaphylaxis was the presenting symptom in seven (30%) patients; all of them were younger than 1 year. Sixteen (70%) were found to be allergic to other foods, and other atopic diseases were identified in 18 (78%) patients. Three patients 'outgrew' their allergy within 1-2 years. Group II (n = 2) included cases in whom sesame allergy was ruled out based on a negative skin prick test (SPT) together with a negative open oral challenge. Group III (n = 7) consisted of patients that were found to be SPT positive for sesame as part of a screening for other food allergies. Although sesame products have become fashionable in westernized countries, early exposure may cause sesame to share eventually the same 'noteriety and fate' as peanut - a major cause of severe food allergic reactions.

Full Text Available To investigate the effects of different fertilizer applications and sesame/cowpea intercropping systems on soil fertility, a split plot experiment based on randomized complete block design was conducted in Fasa, Fars province, during 2014. The main plots were five fertilizer levels consisted of: using chemical fertilizers nitrogen+phosphorous (F1, organic fertilizers (F2, biofertilizers (F3, 50% chemical fertilizer + 50% organic fertilizer (F4 and 50% chemical fertilizer + 50% biofertilizer (F5, and sub plots consisted of: sole cropping of sesame (M1, sole cropping of cowpea (M2, 50:50 sesame-cowpea intercropping (M3, 75:25 sesame-cowpea intercropping (M4 and 25:75 sesame-cowpea intercropping (M5. The results showed that soil fertility and cropping systems affected the yield and yield components of sesame and cowpea significantly. The highest yield of sesame (1292.6 kg.ha-1, and cowpea (3772.4 kg.ha-1 were obtained from their sole croppings. Among the applications of fertilizer, the highest yield of sesame (950.49 kg.ha-1 and cowpea (2582.50 kg.ha-1 belonged to bioorganic and biofertilizer treatments, respectively. In spite of these results, the highest land equivalent ratio (LER belonged to F4 (1.24 and M3 (1.03 treatments.

The mechanism of dehiscence in sesame - features that might be useful in a breeding programme

International Nuclear Information System (INIS)

Day, J.

2001-01-01

By understanding the mechanism of seed retention in sesame, the most appropriate parents for a breeding programme can be identified, and superior lines can be selected more effectively. An initial assessment of some capsule traits thought to be related to seed retention identified varieties with enhanced seed retention under glasshouse conditions. Examination of capsule anatomy and capsule break-strength distinguished two Japanese sesame varieties with particularly good capsule characteristics. These two varieties appeared superior to other lines with a mutation of the id gene, suggesting that traits other than indehiscence might significantly contribute to seed retention. Varieties released commercially by the CSIRO fared poorly in the analyses, providing hope that better varieties can be developed by the CSIRO in the future. (author)

Rheology of Sesame Pastes with Different Amounts of Water Added

Li-Xia Hou

2017-01-01

Full Text Available Sesame paste, usually served as a dressing in some local dishes and the desserts in Southeast Asia and the Middle East, requires mixing with water before consumption to form a thin emulsion of the oil-in-water type. Usually water addition is performed empirically and it is difficult to keep the quality of water-mixed sesame paste consistent. In this study, the rheological behavior of sesame paste with different ratios of sesame paste to added water was investigated. The sesame paste tested contains 59.71% of crude fat and 17% of protein. The ratios of sesame paste to added water (w/v were 1 : 0.75 (T1, 1 : 1 (T2, 1 : 1.25 (T3, and 1 : 1.5 (T4, respectively. All the samples showed the properties of the viscoelastic solids. The samples T1 and T2 behaved as a pseudoplastic material, whereas the apparent viscosity of T3 and T4 remained almost unchanged with the shear rate increasing. T2 had the moderate area of thixotropy loop (57.32 Pa/s among the tested samples and scored the highest in the sensory evaluation. Therefore, our study suggested that ratio of sesame paste to added water of 1 : 1 (w/v is suitable for preparing dressings for different dishes.

Neutron spin echo scattering angle measurement (SESAME)

International Nuclear Information System (INIS)

Pynn, R.; Fitzsimmons, M.R.; Fritzsche, H.; Gierlings, M.; Major, J.; Jason, A.

2005-01-01

We describe experiments in which the neutron spin echo technique is used to measure neutron scattering angles. We have implemented the technique, dubbed spin echo scattering angle measurement (SESAME), using thin films of Permalloy electrodeposited on silicon wafers as sources of the magnetic fields within which neutron spins precess. With 30-μm-thick films we resolve neutron scattering angles to about 0.02 deg. with neutrons of 4.66 A wavelength. This allows us to probe correlation lengths up to 200 nm in an application to small angle neutron scattering. We also demonstrate that SESAME can be used to separate specular and diffuse neutron reflection from surfaces at grazing incidence. In both of these cases, SESAME can make measurements at higher neutron intensity than is available with conventional methods because the angular resolution achieved is independent of the divergence of the neutron beam. Finally, we discuss the conditions under which SESAME might be used to probe in-plane structure in thin films and show that the method has advantages for incident neutron angles close to the critical angle because multiple scattering is automatically accounted for

The effect of using gamma radiation 60 Co on the microbial load , presence of some pathogens, viscosity, oil, fatty acids and amino acids properties of sesame seeds were investigated.The condition storage at ambient temperature (20-28 deg c) was held for one year. Pre-packaged sesame seeds were found to be heavily contaminated with bacteria and fungi. The total bacterial counts were 1,9x10 4 cfu/g,whereas total fungal counts were 3.4x10 4 cfu/g.Samples showed low number of the pathogenic bacterial in control . It was found that the microbiological population greatly reduced with a dose of 10 kGy without affecting their quality attributes , irradiation doses used linearly reduced the viscosity of sesame seeds samples. These irradiation doses caused a decrease in the content of some fatty acids and amino acids and increase in others. At the end of storage period, it is clear that , irradiation dose of 10 kGy greatly reduced the counts of total bacterial count, total fungal count and spore former bacterial to less than 10 cfu/ g. The average counts of faecal coliforms , staphylococcus aureus and enterococcus faecalis did not detected in samples receiving 5 and 10 kGy . the flow index (n) and consistency index (k) were decreased after 12 month of storage in irradiated sesame with 10 kGy. Also, there was a slight increase in acid and peroxide value of oil extracted from sesame seeds treatment with 10 kGy. Meanwhile, there was a decrease in iodine, saponification value and very little decrease in the refractive index. It was found that slightly decreased in total unsaturated fatty acid (0.12%) and total amino acid (0.63%)in sesame irradiated at 10 kGy . so, it can be concluded that 10 kGy of γ-radiation suffice the purpose of this work

Nakagawa, K; Hara, H

2015-01-01

We investigated the location of radical in various sesame seeds using continuous-wave (CW) electron paramagnetic resonance (EPR) and 9-GHz EPR imaging. CW EPR detected persistent radicals (single line) for various sesame seeds. The EPR linewidth of black sesame seeds was narrower than that of the irradiated white sesame seeds. A very small signal was detected for the white sesame seeds. Two-dimensional (2D) imaging using a 9-GHz EPR imager showed that radical locations vary for various sesame seeds. The paramagnetic species in black sesame seeds were located on the seed coat (skin) and in the hilum region. The signal with the highest intensity was obtained from the hilum part. A very low-intensity image was observed for the white sesame seeds. In addition, the 2D imaging of the irradiated white sesame seeds showed that free radicals were located throughout the entire seed. For the first time, CW EPR and 9-GHz EPR imaging showed the exact location of radical species in various sesame seeds.

The experimental treatments were all combination of crop-weed competition (shoot competition, root competition and root-shoot competition and sesame plant densitys (1, 2 and 4 plant per pot. Plants were sown in plastic pots (24 cm diameter and 28 cm height in year 2010, at feild of Ferdowsi University of Mashhad. For study the shoot competition of sesame-pigweed, the roots were separated by plastic when the pots were filled with soil before sowing the seeds. Three weeks after emerging, shoots of plants were separated vertical barrier (30 x 70 cm for studing root competition. Results showed that competition treatments had a significant effect on seed weight per plant and yield components except 1000 seed weight. Among competition produced higher yield and yield components compared to othere treatments. However, sesame and pigweed biological weight in root-shoot competition was 2.6 and 13.7 respectively, that was higher than other competition treatments and was significant. Capsule number in main and sub branches, capsule number in plant, seed number in capsule and seed number in plant in complete competition treatment was 15, 2.58, 17.5, 43.7 and 693.89 respectively, that was higher than other treatments and differences among them was significant. Sesame density also had a significant effect on seed weight per plant and yield components. When low density were used (one plant, yield and yield components was more, therefore in one plant per pot density biological weight of sesame was 3.82 gr, and in higher densities the mentioned traits decreased significantly.

2008-01-01

The performance of mungbean intercropped in sesame under different geometric arrangements was determined o sandy-clay loam soil at the university of Agriculture, Faisalabad for two consecutive years (2001-02). The planting patterns consisted of 40 cm spaced single rows, 60 cm spaced 3-row strips and 100 cm spaced 4-row strip while mungbean was intercropped in all the three planting patterns and also grown as a sole crop. The result evinced that planting sesame in 100 cm spaced 4-row strips explored the intercropping in sesame. It not only permitted convenient intercropping but also facilitated the harvesting and handling of intercrop without doing any damage to the base crop. Intercropping sesame with mungbean in the pattern of 100 cm spaced 4-row strips appeared to be more convenient, productive and profitable than the monocropped sesame. (author)

This newly released EU-EIA-directive 2014/52/EU (hereinafter RL 2014/52) is published within the EU-official journal EU L 124 p. 1 from 25.04.2014, came into force on 15. May 2014 and has to be adopted into international law until 16.05.2017. The modifications made are also valid, apart from certain exceptions, for licensing procedures (including decommissioning of nuclear power plants) in the field of nuclear energy, as far as they might have possible, significant environmental effects. The European EIA directive's 30th ''anniversary'' on 27.06.2015 raises the question, which substantial changes will come soon along with the newly released EU-EIA law. All in all it seems like if authorities and industry might get along with the newly released EU-EIA regulations. The responsible Federal Ministry for the Environment is already working on a first preliminary draft. It is under consideration if the EIA-regulation should be submitted additionally, beyond required amendments by EU-law, to a general revision. EIA-law remains exciting.
Briquetting of Charcoal from Sesame Stalk

Full Text Available Due to the easy availability of wood in Ethiopia, wood charcoal has been the main source fuel for cooking. This study has been started on sesame stalk biomass briquetting which can potentially solve the health problems and shortage of energy, which consequently can solve deforestation. The result of the data collection shows that, using 30% conversion efficiency of carbonizer, it was found that more than 150,000 tonnes of charcoal can be produced from the available sesame stalk in Humera, a place in north Ethiopia. The clay binders that are mixed with carbonized sesame stalk were found to have 69 liquid limits; thus, the optimum amount of clay that should be added as a binder is 15%, which results in better burning and heat holding capacity and better heating time. The developed briquetting machine has a capacity of producing 60 Kg/hr but the carbonization kiln can only carbonize 3.1 Kg in 2 : 40 hours; hence, it is a bottle neck for the briquette production. The hydrocarbon laboratory analysis showed that the calorific value of the charcoal produced with 15% clay content is 4647.75 Cal/gm and decreases as clay ratio increases and is found to be sufficient energy content for cooking.

The field experiment was conducted in a randomized blocks with four treatments and four replicates. The treatments were the sesame and the cowpea bean in intercropping with the cowpea bean planted at the same time, 7, 14 and 21days after than the sesame. A greater part of the production components of both the sesame as well the cowpea bean was affected by the intercropping and significant differences were noted among the treatments in a larger part of the parameters. As the planting of the cowpea bean became more distant from that of the sesame, the yield of the Pedaliaceae increased and the yield of the Fabaceae decreased. The results for LER findings on the other hand suggest that in the sesame/cowpea bean intercropping, when the Fabaceae is planted seven days after the sesame, there is better use of the land and a largest possibility to the producer earning a profit.

Full Text Available The objective of this work was to determine the inheritance mode of seed coat color in sesame. Two crosses and their reciprocals were performed: UCLA37 x UCV3 and UCLA90 x UCV3, of which UCLA37 and UCLA90 are white seed, and UCV3 is brown seed. Results of reciprocal crosses within each cross were identical: F1 seeds had the same phenotype as the maternal parent, and F2 resulted in the phenotype brown color. These results are consistent only with the model in which the maternal effect is the responsible for this trait. This model was validated by recording the seed coat color of 100 F2 plants (F3 seeds from each cross with its reciprocal, in which the 3:1 expected ratio for plants producing brown and white seeds was tested with the chi-square test. Sesame seed color is determined by the maternal genotype. Proposed names for the alleles participating in sesame seed coat color are: Sc1, for brown color; and Sc2, for white color; Sc1 is dominant over Sc2.

Full Text Available In order to evaluation sesame cultivars based on morphological characteristics under water deficit stress condition using factor analysis, an experiment was conducted as a split plot based on randomized complete block design with three replications during 2009 in Research Center of Agriculture and Natural Resources in Parsabad. In this experiment, irrigation as the main factor at three levels (50, 75 and 100 percent of crop water requirement and ten sesame cultivars as the sub-factor were studied. The water requirement of sesame was calculated using CROPWAT software (Penman-Monteith method according to FAO-56. Results showed significant differences between the cultivars and the irrigation levels for all studied traits. Interaction between cultivars and irrigation levels was significant for some of traits. Comparisons of means showed that in water deficit condition, yield and all of traits reduced. In all traits the greatest amounts observed in complete irrigation treatment. In 50 percent of water requirement treatment, amount of leaf chlorophyll, root length, root branches and root length/plant height ratio were greater than other treatments. The Karaj1, Ultan, Naze and IS cultivars were better than other cultivars in stress and non stress condition. In factor analysis 5 and 4 first factors in non stress and stress condition explained 91.36 and 89.52 percent of trait variance, respectively. Grouping of sesame cultivars based on first and second factors in non stress conditions showed that Karaj1, Ultan and Naze cultivars were better than other cultivars. Also, in stress conditions Karaj1 and Ultan cultivars grouped as water deficit stress and better cultivars.

Localizing Play-Based Pedagogy: Nigerian Educators’ Appropriation of Sesame Classroom Materials

Directory of Open Access Journals (Sweden)

Naomi A. Moland

2017-09-01

Full Text Available This article examines how international organizations promote play-based pedagogical approaches in early childhood settings around the world, and how local educators respond. As a case study, I investigated Sesame Workshop’s efforts to introduce play-based approaches in Nigerian classrooms. In addition to producing a Nigerian version of Sesame Street (called Sesame Square, Sesame Workshop trains educators in play-based approaches and has distributed alphabet flashcards, puppet kits, and storytelling games to more than 2,700 early childhood classrooms across Nigeria. These materials were intended to support Sesame Square’s messages, and to foster interactive, child-centered learning experiences. However, teachers often used the materials in ways that reflected more rote-based, teacher centered approaches. Data was gathered through observations and interviews in 27 educational sites across Nigeria that use Sesame materials. Findings reveal that teachers’ resistance to play-based approaches was sometimes for structural reasons (e.g., large class sizes, and sometimes related to their knowledge and training (e.g., they were accustomed to drilling the alphabet. I argue that ideals about constructivist, play-based learning are being disseminated by international organizations—alongside contrasting formalistic pedagogical approaches—and that all approaches will shift as they are localized. I question if approaches that are considered universally developmentally appropriate are relevant in all settings, and explore how early childhood educators adapt global pedagogical trends to make sense in their classrooms. I call for international organizations to explore context-appropriate play-based approaches that develop educators’ capacities to help all children thrive, while also incorporating local cultural beliefs about childhood and teaching.

Full Text Available Sesame seeds were fermented using the traditional method for four days and samples taken for analysis each day till the last day of fermentation to monitor the compositional changes in the seeds as fermentation progressed. The viable count obtained ranged from 8.0×103 after 24 h to 2.93×106 cfu/g on the 4th day. The crude protein and fat content increased as fermentation progressed reaching 27.84% and 51.58% respectively. Fermentation yielded positive effect on the phytic acid, phytin phosphorus and oxalate content of the flour samples when compared with the control. Phytic acid content ranged from 31.59 mg/g for raw seed to 18.13 mg/g for fermented seed flour. Sesame seed are high in minerals such as calcium, magnesium, potassium, sodium and slight increases in values were obtained at the end of processing. Sesame seeds are rich in both essential and non-essential amino acids with leucine, methionine, phenylalanine, threonine and valine values higher than the recommended daily allowance. Processing significantly increased the amino acid values. Sesame flour demonstrated ability to scavenge free radicals. Fermentation of sesame seeds resulted in reduction in the antinutrients in the seed and the seed can serve as soup condiment and seasoning with improved nutritional composition with respect to protein and amino acid.

Chronic kidney disease causes a progressive and irreversible loss of renal function. We investigated the curative effect of sesame oil, a natural, nutrient-rich, potent antioxidant, in a rat model of chronic kidney disease. Chronic kidney disease was induced by subcutaneously injecting uni-nephrectomized rats with deoxycorticosterone acetate (DOCA) and 1% NaCl [DOCA/salt] in drinking water. Four weeks later, the rats were gavaged with sesame oil (0.5 or 1 mL/kg per day) for 7 days. Renal injury, histopathological changes, hydroxyl radical, peroxynitrite, lipid peroxidation, Nrf2, osteopontin expression, and collagen were assessed 24 h after the last dose of sesame oil. Blood urea nitrogen, creatinine, urine volume, and albuminuria were significantly higher in the DOCA/salt treated rats than in control rats. Sesame oil significantly decreased these four tested parameters in DOCA/salt treated rats. In addition, creatinine clearance rate and nuclear Nrf2 expression were significantly decreased in the DOCA/salt treated rats compared to control rats. Sesame oil significantly decreased hydroxyl radical, peroxynitrite level, lipid peroxidation, osteopontin, and renal collagen deposition, but increased creatinine clearance rate and nuclear Nrf2 expression in DOCA/salt treated rats. We conclude that supplementation of sesame oil mitigates DOCA/salt induced chronic kidney disease in rats by activating Nrf2 and attenuating osteopontin expression and inhibiting renal fibrosis in rats. © 2015 Asian Pacific Society of Nephrology.

This study was aimed at investigating the effect of gamma irradiation at various doses (0.5, 1.0, 1.5 and 2.0 kGy) on protein characteristics and functional properties of sesame seeds. Gamma radiation at high doses (>1.0 kGy) significantly (P ≤ 0.05) increased globulin and albumin fractions of sesame protein. Concomitant (P ≤ 0.05) increase of in-vitro protein digestibility was noticed in irradiated sesame flour compared to non-radiated sample. Maximum protein solubility was observed in sesame flour irradiated at 1.0 kGy. SDS-PAGE electrophoretic patterns of total sesame protein were not affected by irradiation process. Significant enhancement (P ≤ 0.05) in emulsification capacity (EC) and emulsion stability (ES) was recorded after irradiation at a dose level of 1.0 and 1.5-2.0 kGy, respectively. Foaming capacity reached a significantly maximum value in sesame flour irradiated at 1.0 kGy while foaming stability was not significantly affected by gamma irradiation. It can be concluded that gamma radiation enhances the protein and functional properties of sesame flour and thus can be employed as an effective method of preserving sesame flour and its products.

Elderly individuals are at increased risk of oral thrush (oral candidiasis) due to decreased saliva secretion. Due to their antimicrobial properties, edible oils can be effective natural agents for oral care. The objective of the present study was to compare the effects of sesame oil, which is widely used for cooking in Asian countries, and two other edible oils on the growth of both mycelial and yeast forms of five clinical isolates of Candida albicans, a causative microorganism of oral thrush. We assessed the effect of each oil in concentrations of 0.078%, 0.156%, and 0.313% on growth of the mycelial forms of the clinical isolates over 24 hr using the crystal violet method. We also evaluated the effect of each oil on growth of the yeast forms by counting the number of viable yeast cells after culturing in the oils for 24 hr. Sesame oil inhibited the growth of both mycelial and yeast forms. Safflower and olive oil also inhibited the growth of both forms of C. albicans but to a lesser extent than sesame oil. The ability to inhibit the growth of the mycelial form correlated with sesame oil concentration. Roasting influenced growth inhibition ability and high-roasted sesame oil most effectively inhibited the yeast form. The growth inhibitory effect differed among the five isolates. We hypothesize that the sesamin and fatty acid components of sesame oil are involved in its antifungal activity. © The Author(s) 2013.

The sesame 2S albumin (2Salb) promoter was evaluated for its capacity to express the reporter gusA gene encoding β-glucuronidase in transgenic tobacco seeds relative to the soybean fad3C gene promoter element. Results revealed increased expression of gusA gene in tobacco seed tissue when driven by sesame 2S albumin promoter. Prediction based deletion analysis of both the promoter elements confirmed the necessary cis-acting regulatory elements as well as the minimal promoter element for optimal expression in each case. The results also revealed that cis-regulatory elements might have been responsible for high level expression as well as spatio-temporal regulation of the sesame 2S albumin promoter. Transgenic over-expression of a fatty acid desaturase (fad3C) gene of soybean driven by 2S albumin promoter resulted in seed-specific enhanced level of α-linolenic acid in sesame. The present study, for the first time helped to identify that the sesame 2S albumin promoter is a promising endogenous genetic element in genetic engineering approaches requiring spatio-temporal regulation of gene(s) of interest in sesame and can also be useful as a heterologous genetic element in other important oil seed crop plants in general for which seed oil is the harvested product. The study also established the feasibility of fatty acid metabolic engineering strategy undertaken to improve quality of edible seed oil in sesame using the 2S albumin promoter as regulatory element.

Full Text Available This study evaluated the nutritional value of sesame and flaxseed oils and their effects on the lipid and glucose profile of rats fed diets containing different fat combinations. Fatty acid composition, refractive index, and iodine and saponification values were analyzed to characterize the oils. In the biological assay, Wistar rats were fed different diets, whose fat composition consisted of varying combinations of flaxseed oil, sesame oil, and animal fat. The primary constituents of the sesame oil were oleic (28.6%, linoleic (28.4%, and lauric acid (14.6%; for the flaxseed oil they were alpha-linolenic (39.90%, oleic (17.97% and linoleic acid (12.25%. The iodine and saponification values of the oils were within the reference range. Rats fed flaxseed oil-based diets had the lowest serum cholesterol values, whereas rats fed diets with flaxseed oil + sesame oil + animal fat had the highest glucose levels. HDL levels decreased significantly with flaxseed oil. Sesame and flaxseed oils are sources of polyunsaturated fatty acids (PUFA, and the flaxseed oil-based diet had a hypocholesterolemic effect, whereas sesame oil showed oxidative stability since it contains high levels of monounsaturated and saturated fatty acids.

An Analysis of “Natural” Food Litigation to Build a Sesame Allergy Consumer Class Action.

Science.gov (United States)

Shaker, Dana

In a world where food allergy is still an incurable disease, law and regulation stand as necessary mechanisms to provide food-allergic consumers with the information they need to protect their health. The Food Allergen Labeling and Consumer Protection Act of 2004 provided specific labeling requirements for the “Top Eight” allergens in the U.S.: milk, soy, gluten, egg, tree nut, peanut, fish, and Crustacean shellfish. Since then, sesame has become more prevalent as an allergen and remains just as dangerous, inducing anaphylactic shock in some sesame-allergic individuals. Yet sesame remains unregulated, despite advocates and congressional members arguing for its inclusion. This note entertains one solution to this problem by exploring the most strategic way to bring a sesame allergy class action against a private food company under California’s consumer protection statutes. Because this kind of class action does not have much, if any, precedent, this note analyzes the basic, preliminary issues that any litigant would have to navigate around to certify a class, including preemption, standing, and the claim itself, by focusing on how courts have examined these issues in the recent “natural” class action litigation. It also analyzes the legal, moral, and practical aspects of choosing a type of relief, as well as whom to include in the class. Finally, this note briefly considers how FDA itself can ensure sesame is regulated on the labels of food products, given that some of the legal issues may well be insurmountable for this particular class action. This note explores the potential solutions to difficult legal hurdles in constructing a sesame allergy class action, arguing that litigating a sesame allergy class action—even if it is not ultimately successful—could start a productive conversation that might lead Congress or FDA to provide greater public health and consumer protection for those with sesame allergy.

In this study sesame liposomes were used to encapsulate both vitamin C and beta-carotene simultaneously. Liposomes were prepared with addition of cholesterol. The encapsulation efficiency (EE) of sesame liposomes for vitamin C in the present of beta-carotene was 77%. The addition of cholesterol increased the encapsulation efficiency. The highest encapsulation efficiency was 89% obtained in liposomes with 10% and 20% cholesterol. Contrary to that, the highest beta-carotene encapsulation efficiency of 78%, was found in the sesame liposomes prepared without the added cholesterol. Results showed that sesame liposomes can be used to encapsulate beta-carotene and vitamin C simultaneously. When beta-carotene and vitamin C were encapsulated concurrently, cholesterol intensified the efficiency of vitamin C encapsulation on the contrary it diminished the efficiency of beta-carotene encapsulation.

Full Text Available Salinity is one of the most restrictions in plant growth in dry and semi dry land which effects production of many crops such as sesame. In order to study the phenology and morphology characteristics of 43 ecotypes and line of sesame (Sesamum indicum L. under salinity of irrigation water (5.2 dS.m-1 a field experiment was conducted at research farm of center of excellence for special crops, Ferdowsi University of Mashhad, Iran, during growing season of 2009-2010 based on a randomized complete block design with three replications. Results showed that four sesame ecotypes could not emerge, 14 sesame ecotypes had appropriate emergence but died before reproductive stage and only 58 % of sesame ecotypes could alive until maturity. There was significant difference between sesame ecotypes for phenological stages and were varied from 64 to 81 days for vegetative and 60 to 65 days for reproductive stages. Plant height, number and length of branches also were different between sesame ecotypes. The highest and the lowest plant height were observed in MSC43 and MSC12 ecotypes, respectively. Number of branches per plant was from 1 to 8 and length of branches in 32 percent of ecotypes was more than 100 cm. There was a considerable correlation between seed weight in plant with reproductive growth (r=0.38** and plant height (r=0.25. In addition different response of sesame ecotypes to saline water and also better morphological indices in some sesame ecotypes may be show the tolerance of these accessions to salinity. More studies may be useful for selection of sesame salt tolerance resources.

Sesame (Sesamum indicum L.) is one of the most important oil crops; however, a lack of useful molecular markers hinders current genetic research. We performed transcriptome sequencing of samples from different sesame growth and developmental stages, and mining of genic-SSR markers to identify valuable markers for sesame molecular genetics research. In this study, 75 bp and 100 bp paired-end RNA-seq was used to sequence 24 cDNA libraries, and 42,566 uni-transcripts were assembled from more than 260 million filtered reads. The total length of uni-transcript sequences was 47.99 Mb, and 7,324 SSRs (SSRs ≥15 bp) and 4,440 SSRs (SSRs ≥18 bp) were identified. On average, there was one genic-SSR per 6.55 kb (SSRs ≥15 bp) or 10.81 kb (SSRs ≥18 bp). Among perfect SSRs (≥18 bp), di-nucleotide motifs (48.01%) were the most abundant, followed by tri- (20.96%), hexa- (25.37%), penta- (2.97%), tetra- (2.12%), and mono-nucleotides (0.57%). The top four motif repeats were (AG/CT)n [1,268 (34.51%)], (CA/TG)n [281 (7.65%)], (AT/AT)n [215 (5.85%)], and (GAA/TTC)n [131 (3.57%)]. A total of 2,164 SSR primer pairs were identified in the 4,440 SSR-containing sequences (≥18 bp), and 300 SSR primer pairs were randomly chosen for validation. These SSR markers were amplified and validated in 25 sesame accessions (24 cultivated accessions, one wild species). 276 (92.0%) primer pairs yielded PCR amplification products in 24 cultivars. Thirty two primer pairs (11.59%) exhibited polymorphisms. Moreover, 203 primer pairs (67.67%) yielded PCR amplicons in the wild accession and 167 (60.51%) were polymorphic between species. A UPGMA dendrogram based on genetic similarity coefficients showed that the correlation between genotype and geographical source was low and that the genetic basis of sesame in China is narrow, as previously reported. The 32 polymorphic primer pairs were validated using an F2 mapping population; 18 primer pairs exhibited polymorphisms between the parents, and 14

Full Text Available The objective of this research work was to determine the characteristic features of the oil content and composition of nutrients of sesame seeds grown in Morocco. Characteristic features of the seed oil revealed a high degree of unsaturation and as determined by gas chromatography reported herein, the major unsaturated fatty acids were linoleic acid (46.9% followed by oleic acid (37.4%, while the main saturated fatty acid was palmitic acid (9.1%. Sesame seed oil was also found to be rich in tocopherols with a predominance of γ-tocopherol (90.5%. The phytosterol marker β-sitosterol accounted for 59.9% of total sterols contained in sesame seed oil. This oil, therefore, has a potential for its use in human nutrition or industrial applications. Compositional analysis revealed that the sesame seeds contained considerable amounts of protein (22% and high amounts of lipids (52%. Nutrient information reported herein illustrates the benefits to public health for consumers of these plant seeds. In terms of oil, sesame seed oil may be considered as a valuable source for new multi-purpose products as industrial, cosmetic, and pharmaceutical uses.

It was recently demonstrated that EOSPAC 6 continued to incorrectly create and interpolate pre-inverted SESAME data tables after the release of version 6.3.2beta.2. Significant interpolation pathologies were discovered to occur when EOSPAC 6's host software enabled pre-inversion with the EOS_INVERT_AT_SETUP option. This document describes a solution that uses data transformations found in EOSPAC 5 and its predecessors. The numerical results and performance characteristics of both the default and pre-inverted interpolation modes in both EOSPAC 6.3.2beta.2 and the fixed logic of EOSPAC 6.4.0beta.1 are presented herein, and the latter software release is shown to produce significantly-improved numerical results for the pre-inverted interpolation mode.

This study was performed to develop a hierarchical approach for detection and quantification of adulteration of sesame oil with vegetable oils using gas chromatography (GC). At first, a model was constructed to discriminate the difference between authentic sesame oils and adulterated sesame oils using support vector machine (SVM) algorithm. Then, another SVM-based model is developed to identify the type of adulterant in the mixed oil. At last, prediction models for sesame oil were built for each kind of oil using partial least square method. To validate this approach, 746 samples were prepared by mixing authentic sesame oils with five types of vegetable oil. The prediction results show that the detection limit for authentication is as low as 5% in mixing ratio and the root-mean-square errors for prediction range from 1.19% to 4.29%, meaning that this approach is a valuable tool to detect and quantify the adulteration of sesame oil.

Full Text Available Oil content and fatty acid composition are very important parameters for the human consumption of oilseed crops. Twenty-four sesame accessions including seven collected from various geographical regions of Turkey and 11 from different countries were investigated under field conditions for two consecutive years (2015 and 2016. The sesame accessions varied widely in their oil content and fatty acid compositions. The oil content varied between 44.6 and 53.1% with an average value of 48.15%. The content of oleic acids, linoleic acid, linolenic acid, palmitic acid,and stearic acid varied between 36.13–43.63%, 39.13–46.38%, 0.28–0.4%, 8.19–10.26%, and 4.63–6.35%, respectively. When total oil content and fatty acid composition were compared, Turkish sesame showed wide variation in oil and fatty acid compositions compared to those from other countries. However, the accessions from other countries were fewer compared to those from Turkey. It is essential to compare oil and fatty acid composition using a large number of germ plasm from different origins. In sesame oil, the average contents of oleic acid and linoleic acid were 39.02% and 43.64%, respectively, and their combined average content was 82.66%, representing the major fatty acid components in the oil from the sesame accessions used in the present study. The results obtained in this study provide useful information for the identification of better parents with high linoleic and oleic acid contents for developing elite sesame varieties with traits which are beneficial to consumer health.

Sesame improvement by induced mutations: Results of the co-ordinated research project and recommendation for future studies

International Nuclear Information System (INIS)

Zanten, L. van

2001-01-01

The FAO/IAEA Co-ordinated Research Project has brought together sesame breeders from 11 countries. They, together with pathologists, agronomists and physiologists, have made considerable effort to advance the genetic improvement in sesame. The results and conclusions from this project cover the mutation techniques used for the genetic improvement of various aspects of sesame. These recommendations do not only deal with the application of mutation induction, but also with the wider plant breeding related objectives and methods to be considered for this semi-domesticated crop. It is clear that more advanced techniques can and should be incorporated in the process which would enhance the genetic improvement. Although five years is a relatively limited time in a plant breeding programme, the participants have been able to produce and make available a considerable pool of agronomically interesting mutant sesame germplasm. The participants in the CRP considered that, together with other specialists, plant breeders can gain fuller benefit from the mutations induced by radiation or chemicals. Work on these mutants must continue in co-operation/consultation with plant physiologists and pathologists, and with biotechnologists who may in the future be able to provide in the future methods for introducing beneficial traits from other crops into sesame. The sesame programme should include scientists from the Member States where sesame grows and scientists from developed countries who may have greater access to physiological and molecular research facilities.

Nonalcoholic fatty liver disease, the most common chronic liver disorder worldwide, comprises conditions from steatosis to nonalcoholic steatohepatitis (NASH) and cirrhosis. NASH is associated with an increased risk of hepatocellular carcinoma. Sesame oil, a healthful food, increases resistance to oxidative stress, inflammation and protects against multiple organ injury in various animal models. We investigated the protective effect of sesame oil against nutritional steatohepatitis in mice. C57BL/6 J mice were fed with methionine-choline deficient (MCD) diet for 28 days to induce NASH. Sesame oil (1 and 2 ml/kg) was treated from 22nd to 28th day. Body weight, steatosis, triglycerides, aspartate transaminase, alanine transaminase, nitric oxide, malondialdehyde, tumor necrosis factor-α, interlukin-6, interleukin-1β, leptin, and transforming growth factor-β1 (TGF-β1) were assessed after 28 days. All tested parameters were higher in MCD-fed mice than in normal control mice. Mice fed with MCD diet for 4 weeks showed severe liver injury with steatosis, oxidative stress, and necrotic inflammation. In sesame-oil-treated mice, all tested parameters were significantly attenuated compared with MCD-alone mice. Sesame oil inhibited oxidative stress, inflammatory cytokines, leptin, and TGF-β1 in MCD-fed mice. In addition, histological analysis showed that sesame oil provided significant protection against fibrotic collagen. We conclude that sesame oil protects against steatohepatitic fibrosis by decreasing oxidative stress, inflammatory cytokines, leptin and TGF-β1. Copyright © 2014 Elsevier Inc. All rights reserved.

Full Text Available Sesame is one of the most important oilseed crops in the world. Irrigation is of great importance to sesame production due to its positive effect on growth parameters. Although sesame has good drought tolerance compared with many other crops, it is particularly susceptible to drought damage during the seedling, flowering and seed filling stages and this can lead to yield loss. The aim of this study was to determine the response of sesame landraces to different irrigation applications during the 2015 growing season. The experiment was set up as a split plot design with three replicates, four main plots (irrigation treatments, designated as 100%, 75% 50% and 0 of the daily crop evapotranspiration and two sub-plots (sesame landraces, Limnos and Evros. Different characteristics such as plant height, number of seeds per capsule, and number of capsules per plant, seed yield, 1000-seed weight and % capsules without seeds, were recorded. The results indicated that all traits except 1000-seed weight were significantly affected by irrigation regimes. Plant height, shattering losses and number of capsules per plant decreased with increasing water shortage. Seed yield and number of seeds per capsule were less affected by irrigation level and showed higher values in the 50% of the daily crop evapotranspiration treatment. Limnos produced higher seed yield and number of seeds per capsule under all irrigation regimes. Evros showed higher plant height and shattering losses than Limnos. The results of this study suggest that sesame landraces can use water efficiently, are locally adapted and associated with traditional farming systems.

Full Text Available Response surface models predict crop yield based on crop density and this is an important tool for evaluation competition at different density and hence selection of optimum density based on yield. In order to study intra and inter specific competition in intercropping bean (Phaseolus vulgaris and sesame (Sesamum indicum, an experiment was conducted at the Agricultural Research Station, Ferdowsi University of Mashhad during the growing season of 2010. For this purpose a complete randomized block design with 3 replications and 16 treatments based on different densities of sesame and bean intercropping was used. The model predicted the maximum yield of an isolated plant of bean and sesame approximately 33 and 17g per plant respectively. The area associated with the maximum yield per plant in bean and sesame were 0.6 and 0.1 m2, respectively. Bean was the dominant competitor with respect to both grain and biomass, and competition coefficient was 0.35 and 0.3 for bean grain yield and bean biomass respectively. Intra-specific competition was more important than inter-specific competition for bean. Competition coefficient was 2.6 and 2.9 for sesame grain yield and biomass respectively. Intra-specific competition was much less important than Interspecific competition in sesame. The highest grain yield in bean (300 g m-2 was obtained of sole crop with density of 20 plants, and the highest sesame grain yield (195 g m-2 was obtained of sole crop with density of 40 plants, the highest land equivalent ratio (1.14 was obtained in intercropping of 20 plants of bean and 10 plants of sesame.
SESAME: Exploring small businesses’ behaviour to enhance resilience to flooding

Full Text Available In the United Kingdom, small and medium sized enterprises (SMEs account for approximately 99.9% of businesses, 60% of the working population and 47% annual turnover. However, despite the important contribution that SMEs make to the economy, this size of business remains under-researched with a significant gap in understanding how the disruption caused by flooding impacts on SMEs from the time at which a flood event occurs through to the ‘return’ to normal operations. Business continuity management is a recognised approach for enhancing organisational resilience to major disruptions (ISO 22301, 2012. However, this strategic approach to building such resilience in SMEs is under-explored in the literature with a limited range of empirical data to draw on. This paper presents an overview of an inter-disciplinary research project funded by the UK’s Engineering and Physical Science Research Council, called SESAME, which examines SMEs’ operational response and preparedness to flooding. Furthermore, SESAME consists of four stands of research which bring together a number of disciplines including agent based modelling and simulation, flood modelling, business continuity management, economic modelling and behavioural science. This paper provides an overview of the different research stands within the SESAME project aimed at enhancing SMEs’ resilience to flooding.

Phyllody, a destructive and economically important disease worldwide caused by phytoplasma infections, is characterized by the abnormal development of floral structures into stunted leafy parts and contributes to serious losses in crop plants, including sesame (Sesamum indicum L.). Accurate identification, differentiation, and quantification of phyllody-causing phytoplasmas are essential for effective management of this plant disease and for selection of resistant sesame varieties. In this study, a diagnostic multiplex qPCR assay was developed using TaqMan® chemistry based on detection of the 16S ribosomal RNA gene of phytoplasmas and the 18S ribosomal gene of sesame. Phytoplasma and sesame specific primers and probes labeled with different fluorescent dyes were used for simultaneous amplification of 16SrII and 16SrIX phytoplasmas in a single tube. The multiplex real-time qPCR assay allowed accurate detection, differentiation, and quantification of 16SrII and 16SrIX groups in 109 sesame plant and 92 insect vector samples tested. The assay was found to have a detection sensitivity of 1.8 x 102 and 1.6 x 102 DNA copies for absolute quantification of 16SrII and 16SrIX group phytoplasmas, respectively. Relative quantification was effective and reliable for determination of phyllody phytoplasma DNA amounts normalized to sesame DNA in infected plant tissues. The development of this qPCR assay provides a method for the rapid measurement of infection loads to identify resistance levels of sesame genotypes against phyllody phytoplasma disease.

Full Text Available Drought is one of the most important abiotic stresses that impair sesame (Sesamum indicum L. productivity mainly when it occurs at flowering stage. However up to now, very few studies have attempted to investigate the molecular responses of sesame to drought stress. In this experiment, two genotypes having contrasting responses to drought (tolerant and sensitive were submitted to progressive drought followed by recovering stage at flowering stage. RNAs were isolated from roots of plants before drought stress, at 3-time points during progressive drought, after rewatering, and sequenced using Illumina HiSeq 4000 platform. These RNA-Seq resources (BioSample IDs: SAMN06130606 and SAMN06130607 provided an opportunity to elucidate the molecular responses of sesame to drought and find out some candidate genes for drought tolerance improvement.
Relationship between metabolic and genomic diversity in sesame (Sesamum indicum L.

Full Text Available Abstract Background Diversity estimates in cultivated plants provide a rationale for conservation strategies and support the selection of starting material for breeding programs. Diversity measures applied to crops usually have been limited to the assessment of genome polymorphism at the DNA level. Occasionally, selected morphological features are recorded and the content of key chemical constituents determined, but unbiased and comprehensive chemical phenotypes have not been included systematically in diversity surveys. Our objective in this study was to assess metabolic diversity in sesame by nontargeted metabolic profiling and elucidate the relationship between metabolic and genome diversity in this crop. Results Ten sesame accessions were selected that represent most of the genome diversity of sesame grown in India, Western Asia, Sudan and Venezuela based on previous AFLP studies. Ethanolic seed extracts were separated by HPLC, metabolites were ionized by positive and negative electrospray and ions were detected with an ion trap mass spectrometer in full-scan mode for m/z from 50 to 1000. Genome diversity was determined by Amplified Fragment Length Polymorphism (AFLP using eight primer pair combinations. The relationship between biodiversity at the genome and at the metabolome levels was assessed by correlation analysis and multivariate statistics. Conclusion Patterns of diversity at the genomic and metabolic levels differed, indicating that selection played a significant role in the evolution of metabolic diversity in sesame. This result implies that when used for the selection of genotypes in breeding and conservation, diversity assessment based on neutral DNA markers should be complemented with metabolic profiles. We hypothesize that this applies to all crops with a long history of domestication that possess commercially relevant traits affected by chemical phenotypes.

Sesame (Sesamum indicum L.) is one of the world's most important oil crops. However, it is susceptible to abiotic stresses in general, and to waterlogging and drought stresses in particular. The molecular mechanisms of abiotic stress tolerance in sesame have not yet been elucidated. The WRKY domain transcription factors play significant roles in plant growth, development, and responses to stresses. However, little is known about the number, location, structure, molecular phylogenetics, and expression of the WRKY genes in sesame. We performed a comprehensive study of the WRKY gene family in sesame and identified 71 SiWRKYs. In total, 65 of these genes were mapped to 15 linkage groups within the sesame genome. A phylogenetic analysis was performed using a related species (Arabidopsis thaliana) to investigate the evolution of the sesame WRKY genes. Tissue expression profiles of the WRKY genes demonstrated that six SiWRKY genes were highly expressed in all organs, suggesting that these genes may be important for plant growth and organ development in sesame. Analysis of the SiWRKY gene expression patterns revealed that 33 and 26 SiWRKYs respond strongly to waterlogging and drought stresses, respectively. Changes in the expression of 12 SiWRKY genes were observed at different times after the waterlogging and drought treatments had begun, demonstrating that sesame gene expression patterns vary in response to abiotic stresses. In this study, we analyzed the WRKY family of transcription factors encoded by the sesame genome. Insight was gained into the classification, evolution, and function of the SiWRKY genes, revealing their putative roles in a variety of tissues. Responses to abiotic stresses in different sesame cultivars were also investigated. The results of our study provide a better understanding of the structures and functions of sesame WRKY genes and suggest that manipulating these WRKYs could enhance resistance to waterlogging and drought.

In 1994, the study of sesame improvement for reduction of seed loss by mutation was conducted at Ubonratchathani Field Crops Research Center (UBFCRC). There were two experiments carried out to improve sesame capsule for non-shattering characteristics using gamma rays and fast neutrons. The first experiment was performed to study the effect of irradiation doses on sesame when applied at doses varying from 200 to 750 Gy. Results of the experiments showed that all sesame lines had LD 50 levels between 300-750 Gy when irradiated with gamma rays, and 20-80 Gy with fast neutron. The second experiment was done to investigate the effect of irradiation on shattering types of sesame capsules. Three local varieties, Red Pitsanulok, Black Burirum and white Granuan were irradiated with 500 Gy of gamma rays. In the dry season 1997-98, 24 plants of M 7 generation (black- and red- seeded lines) and 8 plants of M 5 generation (white-seeded lines) were selected for yield evaluation with three local varieties. The results show 3 shatter resistant lines, PMUB 1, PMUB 19 (both with shatter resistance scale 537) and GMUB 7 (with scale 637) in 1997-98 (772 in 1997) gave 27% higher seed yield than the original variety; 2 black seeded mutant lines BMUB 21 and BMUB 23 of which seed colour slowly fades and 2 mutant lines (GMUB 1, GMUB 3) with a high degree of tolerance to powdery mildew.

The aim of intercropping is optimizing the use of space, time and physical resources in both the top and under of the soil surface through maximizing positive relationship and minimizing negative relationship between the components of agricultural ecosystems. In intercropping due to better use of available resources such as land, labor, time, light, water and nutrients, as well as reducing damages caused by pests and diseases and socio-economic advantages, increase in production per unit area can be expected. In this study, yield and yield components of sesame and bean in additive and replacement intercropping with mixed and row planting type was evaluated and the possible advantages of intercropping to monoculture as well as the types of intercropping were compared. Materials and Methods This experiment was conducted in Agricultural Research Station of Ferdowsi University of Mashhad, located in 10 kilometers south-east of the city of Mashhad, Iran (latitude 36° 17′ N, longitude 59° 35′ E and 985 m elevation in 2013 and 2014. Climate of the area is cold and dry. A Split-Plot experiment based on randomized complete block design with three replications was used with the factor of cropping system (as main plot and intercropping proportions (as sub plot. The cropping system was included; mixed and row cropping and intercropping proportions were included; monoculture of bean (100b, 25% sesame- 75% bean (25s75b, 50% sesame- 50% bean (50s50b, 75% sesame- 25% bean (75s25b, monoculture of sesame (100s, 10% bean- 100% sesame (10b100s, 20% bean- 100% sesame (20b100s, 30% bean- 100% sesame (30b100s, 100% bean- 10% sesame (100b10s, 100% bean- 20% sesame (100b20s, and 100% bean- 30% sesame (100b30s.

Full Text Available Phyllody, a destructive and economically important disease worldwide caused by phytoplasma infections, is characterized by the abnormal development of floral structures into stunted leafy parts and contributes to serious losses in crop plants, including sesame (Sesamum indicum L.. Accurate identification, differentiation, and quantification of phyllody-causing phytoplasmas are essential for effective management of this plant disease and for selection of resistant sesame varieties. In this study, a diagnostic multiplex qPCR assay was developed using TaqMan® chemistry based on detection of the 16S ribosomal RNA gene of phytoplasmas and the 18S ribosomal gene of sesame. Phytoplasma and sesame specific primers and probes labeled with different fluorescent dyes were used for simultaneous amplification of 16SrII and 16SrIX phytoplasmas in a single tube. The multiplex real-time qPCR assay allowed accurate detection, differentiation, and quantification of 16SrII and 16SrIX groups in 109 sesame plant and 92 insect vector samples tested. The assay was found to have a detection sensitivity of 1.8 x 102 and 1.6 x 102 DNA copies for absolute quantification of 16SrII and 16SrIX group phytoplasmas, respectively. Relative quantification was effective and reliable for determination of phyllody phytoplasma DNA amounts normalized to sesame DNA in infected plant tissues. The development of this qPCR assay provides a method for the rapid measurement of infection loads to identify resistance levels of sesame genotypes against phyllody phytoplasma disease.

Gamma rays of average energy of 1.25 MeV from radionuclide 60 Co was used in this study and the effects of varying doses 3, 6, 9, 12, 15 kGy on fungal load of and mycotoxin content on sesame seeds were investigated. Sesame seed samples were collected from Abaji, Gwagwalada, Kubwa and Karu markets in Abuja, Federal Capital Territory, Nigeria. A serial dilution technique was employed and the fungi so diluted from the sesame seed samples were identified based on micro and macro morphological characteristics. The Aflatoxin Total and Ochratoxin A Contents in the samples were analysed using AgraQaunt direct combative enzyme-linked immunosorbent assay (ELISA). In all, 157 fungal isolates to four genera: Aspergillus, Curvularia, Penicillium, and Fusarium spp. in decreasing order of predominance were identified. Aspergillus spp. were observed from all the nonirradiated samples. Doses of 6-15kGy eliminated the entire fungal load. Also doses of 9-15kGy generally reduced Ochratoxin A content in all the samples, the rate of mycotoxin reduction was inconsistent with absorbed dose. However, sesame seed samples from the four markets exposed to irradiation dose of 15kGy had the comparatively least Aflatoxin Total content.

Screening for aroma-active compounds in an aroma distillate obtained from freshly pan-roasted sesame seeds by aroma extract dilution analysis revealed 32 odorants in the FD factor range of 2-2048, 29 of which could be identified. The highest FD factors were found for the coffee-like smelling 2-furfurylthiol, the caramel-like smelling 4-hydroxy-2,5-dimethyl-3(2H)-furanone, the coffee-like smelling 2-thenylthiol (thiophen-2-yl-methylthiol), and the clove-like smelling 2-methoxy-4-vinylphenol. In addition, 9 odor-active thiols with sulfurous, meaty, and/or catty, black-currant-like odors were identified for the first time in roasted sesame seeds. Among them, 2-methyl-1-propene-1-thiol, (Z)-3-methyl-1-butene-1-thiol, (E)-3-methyl-1-butene-1-thiol, (Z)-2-methyl-1-butene-1-thiol, (E)-2-methyl-1-butene-1-thiol, and 4-mercapto-3-hexanone were previously unknown as food constituents. Their structures were confirmed by comparing their mass spectra and retention indices as well as their sensory properties with those of synthesized reference compounds. The relatively unstable 1-alkene-1-thiols represent a new class of food odorants and are suggested as the key contributors to the characteristic, but quickly vanishing, aroma of freshly ground roasted sesame seeds.

Full Text Available A laboratory experiment was conducted to determine the effect of ultrasound (US exposure time on germination behavior of sesame seeds. All tests were carried out at 20 kHz in a water bath ultrasonic device varying two factors, treatment duration (10, 20 and 30 min and germination temperature (15, 20 and 25 ºC. Parallel tests were run in which seeds were soaked in water without sonication in order to eliminate the effect of water from US test results. US treatments enhanced seeds water uptake. At mild exposure time it improved sesame seed germination performance and seedling growth at suboptimal temperatures as indicated by higher germination percentage and germination rate. US applying for 20 min had relatively high superoxide dismutase activity; however, had not significant differences with control and US duration for 10 min. The catalase activity was strongly increased by applying the US for a 10 and 20 min. Among the treatments, application of US vibration for 10 and 20 min reduced both of malondialdehyde and H2O2 contents, however high US duration (30 min increased both of the traits. In general, ultrasonic priming technique can be useful for early planting the sesame seeds, and lead to higher yields.

''Suwon 144'', derived from the cross between ''Danbaeckkae'' and mutant MY-74-2 and in spite of its higher yield and quality compared to the check variety, did not pass the nomination to the Committee of Main Crops New Varieties under the Ministry of Agriculture and Forestry, due to the decision of the committee to limit the number of new varieties in sesame as a minor crop in Korea. ''Suwon 144'' will be released again for a fifth year to RYT in 1998. 5,282 cross combinations and 4,341 lines including 1,388 crossings of F 1 were crossed and released to the experimental field of NCES in 1997. Mutants and their cross combinations were released and constituted more than half among them. Seeds of ''Suwon 152'' were treated with NaN 3 and tested for germinability. The other seeds were released and harvested in the experimental field and 419 mutant lines were selected among all the mutant lines. Mutants or materials from cross breeding with mutants occupied 71% (675) among a total of 952 promising lines in yield trials of OYT, PYT, AYT and RYT. For variability of NaN 3 induced genetic male sterile (GMS) mutants and development of restorer/s of GMS, GMS lines were planted, and male sterility (MS) expression evaluated on each line. The selected 4 MS lines with 50% MS were crossed in 22 combinations with 7 recommended varieties. For development of genic-cytoplasmic MS (GCMS) using NaN 3 induced GMS mutants, 40 recommended local Korean and introduced cultivars were crossed in 57 combinations with 4 selected GMS lines expressing 50% male sterility. Various and many sources of unique characteristics have been continuously created through induced mutations, such as determinate; dwarf, lodging,- Phytophthora blight- and shatter- resistant; indehiscent, seamless, taller, stronger thick stems, dense capsule bearing type, semi-dwarf, better maturity, male sterility, smaller seeds, pure white seed coat color and high yields.

Full Text Available Carbon dioxide is the most important resource for crop growth. In order to investigate the effect of elevated CO2 concentration on morphological and physiological characteristics of sesame (Sesamum indicum L. and amaranthus (Amaranthus retroflexus L. an experiment was conducted in greenhouse conditions. The experiment was factorial based on randomized complete block design with six treatments and three replications. Different CO2 concentrations (including 360, 520 and 750 ppm on monoculture and mixture of two species were investigated. The results indicated that plant height, node number, internode and stem dry weight had significant differences in the CO2 concentrations. Elevated CO2 concentration caused increasing plant height, node number, internode and stem dry weight in sesame and monoculture was better than mixtures, but in the amaranthus, elevated CO2 concentration resulted is decreasing plant height, node number, and internode and stem dry weight. Number and length of branches and their dry weight had significant different in CO2 concentrations. So, effect of elevated CO2 concentration was positive for sesame and negative for amaranthus. In amaranthus, monoculture was more successful than mixture. In the sesame, yield was included number and weight capsule and in the amaranthus was included total seed weight, that both had significant affected. Elevated CO2 concentration had positive effect on yield of sesame and negative effect on yield of amaranthus. In the sesame, monoculture was more successful. The effect of elevated CO2 concentration was significant on transpiration and photosynthesis rates. In the sesame, elevated CO2 concentration increased transpiration and photosynthesis rates and decreased them in the amaranthus. In the sesame, shoot total length and root dry weight was significantly different in CO2 concentrations and increased by elevated CO2 concentration, but in the amaranthus, decreased by elevated CO2 concentration�

Full Text Available Sesame is an important oil crop widely cultivated in Africa and Asia. Understanding the genetic diversity of accessions from these continents is critical to designing breeding methods and for additional collection of sesame germplasm. To determine the genetic diversity in relation to geographical regions, 96 sesame accessions collected from 22 countries distributed over six geographic regions in Africa and Asia were genotyped using 33 polymorphic SSR markers. Large genetic variability was found within the germplasm collection. The total number of alleles was 137, averaging 4.15 alleles per locus. The accessions from Asia displayed more diversity than those from Africa. Accessions from Southern Asia (SAs, Eastern Asia (EAs, and Western Africa (WAf were highly diversified, while those from Western Asia (WAs, Northern Africa (NAf, and Southeastern Africa (SAf had the lowest diversity. The analysis of molecular variance revealed that more than 44% of the genetic variance was due to diversity among geographic regions. Five subpopulations, including three in Asia and two in Africa, were cross-identified through phylogenetic, PCA, and STRUCTURE analyses. Most accessions clustered in the same population based on their geographical origins. Our results provide technical guidance for efficient management of sesame genetic resources in breeding programs and further collection of sesame germplasm from these different regions.

Full Text Available Sesame oil produced by the traditional aqueous extraction process (TAEP has been recognized by its pleasant flavor and high nutrition value. This paper developed a rapid and nondestructive method to predict the sesame oil yield by TAEP using near-infrared (NIR spectroscopy. A collection of 145 sesame seed samples was measured by NIR spectroscopy and the relationship between the TAEP oil yield and the spectra was modeled by least-squares support vector machine (LS-SVM. Smoothing, taking second derivatives (D2, and standard normal variate (SNV transformation were performed to remove the unwanted variations in the raw spectra. The results indicated that D2-LS-SVM (4000–9000 cm−1 obtained the most accurate calibration model with root mean square error of prediction (RMSEP of 1.15 (%, w/w. Moreover, the RMSEP was not significantly influenced by different initial values of LS-SVM parameters. The calibration model could be helpful to search for sesame seeds with higher TAEP oil yields.

Genetic diversity among 20 sesame (Sesamum indicum L.) accessions was examined at DNA level by means of random amplified polymorphic DNA (RAPD) analysis. Ten primers used produced a total of 93 RAPD fragments, of which 70 (75%) were polymorphic. Each primer generated 5 to 17 amplified fragments with an average of 9.3 bands per primer. Based on pair-wise comparisons of RAPD amplification products, Nei and Li's similarity coefficients were computed to assess the associations among the accessions. Pair-wise similarity indices varied from 0.65 to 0.91. A UPGMA cluster analysis based on these genetic similarities located most of the accessions far apart from one another, showing a high level of polymorphism. Genetically, all the genotypes were classified into two major groups and six subgroups or clusters. A single accession (22243) was relatively distinct from rest of the accessions and created independent cluster. In conclusion, even with the use of a limited set of primers, RAPD technique revealed a high level of genetic variation among sesame accessions collected from diverse ecologies of Pakistan. This high level of genetic diversity among the genotypes suggested that RAPD technique is valuable for sesame systematic, and can be helpful for the upholding of germplasm banks and the competent choice of parents in breeding programs.

This experiment was conducted as factorial based on randomized complete block design with three replications. The first and the second factors were biofertilizers (Nitragin, Nitroxin, bio-phosphorus and control and water volume per irrigation (100, 200 and 300 ml, respectively. The results showed that the simple effects of biofertilizer and irrigation volume were significant (p≥0.05 on plant height, the first internode length, number and dry weight of leaves, dry weight of stem, chlorophyll content and relative water content (RWC of sesame. Also, interaction between biofertilizer and water volume per irrigation was significant (p≥0.05 plant height and RWC. The maximum and the minimum sesame seed yield were observed in Nitragin and control with 204.4 and 100.0 kg.m-2, respectively. The highest seed yield was observed in 100 ml (202.1 kg.m-2 and the lowest was achieved with 300 ml (170.1 kg.m-2 per irrigation water. Application of biofertilizers enhanced root development and hence availability of moisture and nutrients, particularly nitrogen and phosphorus. On the other hand, since these fertilizers are promote of growth regulator and hence in basement of growth and photosynthesis of sesame. With increasing irrigation volume from 100 to 300 ml, growth of sesame was decreased. Therefore, sesame application of biofertilizers could improve its vegetative characteristics in dry and semi-dry regions.

Fusarium-infected sesame plants have significantly higher contents of amino acids (Asp, Thr, Ser, Asn, Glu, Gly, Ala, Val, Met, Ile, Leu, Tyr, Phe, Lys, His, Try, Arg, and Pro), compared with their respective levels in the healthy control. These higher levels of amino acids induced by Fusarium infection were decreased when Penicillium was co-inoculated with Fusarium. Compared with the control, Fusarium-infected plants showed higher contents of palmitic (8%), stearic (8%), oleic (7%), and linolenic acids (4%), and lower contents of oil (4%) and linoleic acid (11%). Co-inoculation with Penicillium mitigated the Fusarium-induced changes in fatty acids. The total chlorophyll content was lower in Fusarium- and Penicillium-infected plants than in the healthy control. The accumulation of carotenoids and γ-amino butyric acid in Fusarium-infected plants was slightly decreased by co-inoculation with Penicillium. Sesamin and sesamolin contents were higher in Penicillium- and Fusarium- infected plants than in the control. To clarify the mechanism of the biocontrol effect of Penicillium against Fusarium by evaluating changes in primary and secondary metabolite contents in sesame plants.

Full Text Available Fertilization and harvest time may influence the formation and maturation processes, as well as the physiological quality of seeds. This study aimed at evaluating the effect of fertilization on the physiological maturation of sesame seeds. The following variables were evaluated: fruit color, dry mass and water content of fruits and seeds, germination, first germination count, germination speed, emergence and emergence speed. No significant fertilization effect was observed on fruit maturation for water content or dry mass. However, there was significance for these variables in the seeds. The harvest time had a significant effect on water content and dry mass of fruits and seeds. For the variables that evaluated the seed viability and vigor, both the fertilization and harvest time influenced the physiological maturation. The physiological maturity of the sesame seeds, whose plants were grown with and without fertilization, was reached between 52 and 54 days after anthesis, when the fruits were classified as yellow-greenish 7.5 Y 8/6 and yellow to yellow-red 10.R 4/6.

Many studies were carried out to improve sophisticated dressings to accelerate healing processes and reduce the microbial burden in burn wounds. This study evaluated the healing effect of herbal ointment containing extract of sesame oil, camphor and honey on second degree burn wounds in rats in comparison with daily dressing oil vaseline. Forty rats were randomly assigned to two equal groups. A deep second degree burn was formed on the back of each rat with using a standard burning technique. The burns were dressed daily with herbal ointment containing extract of sesame oil, camphor and honey in group 1, dressing oil vaseline in group 2. The response to treatment was evaluated by digital photography during the treatment on 0, 7, 14, 21, 28 days. Histological scoring was undertaken for scar tissue samples on 0, 7, 14, 21, 28 days. Considerable epithelization in the herbal ointment group vs. the control group over the study period was noted. Neovascularization was significantly higher in herbal ointment treated rats as well. In terms of difference of wound surface area, maximal healing was noticed in herbal ointment extract of sesame oil, camphor and honey group and the minimal repair in the control group. The greatest rate of healing was in the herbal ointment group containing sesame oil, camphor and honey, so the herbal ointment as a suitable substitute for dressing and healing of burn wound injuries is recommended.

Full Text Available Seed germination is a crucial stage in the plant life cycle and salt tolerance during germination stage is vital for the establishment of plants in saline soils. In order to evaluation of sesame (Sesamum indicum landraces germination to salinity stress at different temperature, an experiment was conducted at Ferdowsi University of Mashhad, Collage of Agriculture during 2009. Experimental type was complete randomized design in factorial arrangement with 4 replications. Factors included salinity at 7 levels (0, -2, -3, -4, -6, -8, -10 and -12 bar, temperature at 3 levels (15°c, 20°c, 25°c and 3 sesame landraces (Sabzevar, Kalat and Oltan. Results showed that germination parameters (germination percentage, germination rate, root length, shoot length, dry weight of roots and dry weight of shoots in all landraces were significantly (p≤0.01 affected by salinity and temperature. Increasing salinity reduced all above parameters in sesame cultivars, so that highest tolerated dose of salt was obtained in 25°c and increasing of temperature reduced effects of salinity. The highest germination percent was observed in salinity between 0 to -4 bar at 25°c. Sabzevar and Oltan landraces exhibited the highest and the lowest indicators at different temperatures respectively. According to these results, it seems that in saline condition and temperature variation, Sabzevar is the appropriate sesame landraces for optimal seedling establishment.

A semiconductor saturable absorber mirror (SESAM) passively mode-locked fiber laser with a long cavity length over 700 m is demonstrated. A band pass filter is inserted into the laser cavity to stabilize the lasing wavelength. Some interesting phenomena are observed and discussed. The central wavelength, repetition rate, average power and single pulse energy of the laser are 1064 nm, 281.5 kHz, 11 mW and 39 nJ, respectively. The laser operates stably without Q-switching instabilities, which greatly reduces the damage opportunities of the SESAM

The plant (Sesamum indicum) is a lovely annual shrub with white bell-shaped flowers tinged with a hint of blue, red or yellow. The rich, almost odourless oil expressed from the tiny seeds is very stable and contains an antioxidant system comprising sesamol and sesamolinol formed from sesamolin, which substantially reduces its oxidation rate. The objective of this study was designed to evaluate the efficacy of sesame oil to reduce the altered biochemical indices in brain of irradiated rats exposed to argon laser at wavelength 488 nm. Methods: Animals were divided into 4 groups. Group 1: Control group where 6 rats are dissected as control for other irradiated rats. Group 2: Irradiated with argon laser at wavelength 488 nm receiving energy (1.0 J x 3 times) on head of rats day by day. Group 3: Animals administered with sesame oil 500 mg/kg body wt/day for 20 successive days. Group 4: Irradiated with argon laser at wavelength 488 nm receiving an energy (1.0 J x 3 times) animals administered with sesame oil 500 mg/kg body wt/day through the radiation. Each group was dissected after 1, 9 and 14 days after exposure to laser radiation (presented in NCRRT). Results: The use of naturally occurring agents as antioxidant agents as sesame oil can slow the degenerative process in several neuro degenerative diseases. These data are addition to the antioxidant properties of the sesame oil against argon laser at wavelength 488 nm to indicate a possible role for the use in treatment of diseases involving free radicals and oxidative damage

Full Text Available Sesame (Sesamum indicum is one of the most important cash crops grown extensively for its seeds in Ethiopia. Production of sesame in the country is very crucial in many aspects, but the invasion of the cotton mealybug, Phenacoccus solenopsis Tinsley, is becoming a big deal in its production. A survey for mealybug infestation was conducted during 2016 production season in 15 localities of “Kafta Humera” district so as to assess the incidence and severity of the pest. In each locality 2 sesame farms have been selected and 6 samples per farm (2 samples from the road sides, 2 from camp surrounding, and 2 from the central part of the farms have been checked. During the survey, “Bowal” and “Sherif Hamad” have scored the higher incidence and severity of mealybugs. Road sides and camp surrounding of the farms were shown to have severe infestation. Stony and oxen plowed farms were also intensively invaded with cotton mealybugs. The pest has different natural means to infest new areas; thus its control measure has to be developing timely.

Full Text Available Background: Phlebitis is the most common complication associated with peripheral intravenous infusion of amiodarone. The purpose of this study is to determine the effects of sesame oil on the prevention of amiodarone-induced phlebitis. Materials and Methods: This is a double-blind randomized controlled trial. Thirty-six patients hospitalized in a coronary care unit were randomly allocated into two groups using a convenience sampling method. Following peripheral intravenous cannulation, five drops of pure sesame oil were applied to the skin within a 10 cm radius of the infusion site prior to the administration of amiodarone in the intervention group. Sesame oil was rubbed on the skin at the infusion site every 6 h in the 24-h period of amiodarone infusion. In the control group, liquid paraffin, used as a placebo, was rubbed on the skin at the infusion site of amiodarone. Both groups were monitored for the development of phlebitis and its degree within the 24-h period of amiodarone infusion as well as 6 h after its administration. The incidence of phlebitis was confirmed and recorded by an assessor who was blind to the two groups. Data were analyzed using Statistical Package for Social Science (SPSS version 18, and descriptive and inferential statistics such as Chi-square test, Kaplan-Meier, Hazard ratio, independent t-test, and Fisher′s exact test. Results: There was a statistically significant difference between the two groups in their catheter survival after 30 h and 10 min ( P < 0.001. Over 60% of the patients (61.1% in the intervention group did not show any sign of phlebitis, while 16.7% and 22.2% of the patients manifested signs of grade 2 and 3 phlebitis, respectively. In the control group, 22.2% of the patients showed no signs of phlebitis, while 5.6%, 27.8%, and 44.4% of the patients exhibited signs of grade 2, 3, and 4 phlebitis, respectively. The statistical analysis showed significant differences in the degree of phlebitis ( P = 0

The SESAME plan has been implemented at the Thies Regional Hospital Center (TRHC) for one year. The purpose of this study was to analyze the financial implications of the plan on the hospital budget for the sustainability of care for persons aged 60 and over. This descriptive study included analysis of budget data from October 2006 to September 2007 plus information obtained by interviewing the accountant and head of SESAME plan. The number of patients managed, sources of CHRT funding, grants from various SESAME plan partners, and expenditures for each partner were determined. The weight of the SESAME plan in the CHRT operating budget was determined by calculating the ratio of the overall cost of care for elderly persons in relation to the hospital's revenues and SESAME grants. During the study period, the CHRT received a total of 17375 elderly persons including 89% with no pension or social security. The institute pension scheme (IPRES) covered 21% of the plan as compared to 79% for the state. Utilization plan grants in relation to funding source was 41% for IPRES and 124% for the State. The total cost of services provided to beneficiaries of the SESAME plan exceeded the aggregate amount by 26 083 847 CFA francs. The weight of the SESAME plan in the operating cost of the CHRT was 17%. Prefinancing a plan to cover elderly care in hospitals should be sufficient to prevent deficits from impacting negatively on the operating budget of the hospital.

Full Text Available Abstract Background Sesame is an important oil crop in tropical and subtropical areas. Despite its nutritional value and historic and cultural importance, the research on sesame has been scarce, particularly as far as its genetic diversity is concerned. The aims of the present study were to clarify genetic relationships among 32 sesame accessions from the Venezuelan Germplasm Collection, which represents genotypes from five diversity centres (India, Africa, China-Korea-Japan, Central Asia and Western Asia, and to determine the association between geographical origin and genetic diversity using amplified fragment length polymorphism (AFLP. Results Large genetic variability was found within the germplasm collection. A total of 457 AFLP markers were recorded, 93 % of them being polymorphic. The Jaccard similarity coefficient ranged from 0.38 to 0.85 between pairs of accessions. The UPGMA dendrogram grouped 25 of 32 accessions in two robust clusters, but it has not revealed any association between genotype and geographical origin. Indian, African and Chinese-Korean-Japanese accessions were distributed throughout the dendrogram. A similar pattern was obtained using principal coordinates analysis. Genetic diversity studies considering five groups of accessions according to the geographic origin detected that only 20 % of the total diversity was due to diversity among groups using Nei's coefficient of population differentiation. Similarly, only 5% of the total diversity was attributed to differences among groups by the analysis of molecular variance (AMOVA. This small but significant difference was explained by the fact that the Central Asia group had a lower genetic variation than the other diversity centres studied. Conclusion We found that our sesame collection was genetically very variable and did not show an association between geographical origin and AFLP patterns. This result suggests that there was considerable gene flow among diversity centres

This research is designed to determine the efficacy of DBD plasma to reduce the microbial contamination of pepper and sesame powder. The AC high voltage power supply was used with voltages of up to 20 kV and the frequency of 5.5 kHz was applied to the DBD. The gap of DBD electrodes was set at 5 mm. In raw initial samples, the total aerobic count of pepper (Piper nigrum) was found at quite a high level at 5.40 × 105 CFU/g. Coliform bacteria was also found in both the sesame (Sesamum indicum Linn.) powder and pepper (Piper nigrum) powder. Both kinds of samples were treated with plasma for 2, 4, 6 and 10 minutes. Results indicated that plasma treatment at 2-10 minutes reduced the total aerobic count of pepper allowed to achieve the acceptable microbial level for spices. The plasma treatment times in this experiment were also effective in reducing faecal coliform bacteria in both pepper and sesame powders (MPN/g <3) as indicated in the standard. Plasma from dielectric barrier charge can reduce Staphylococcus epidermidis in sesame powder which was artificially contaminated with 3.50 × 102 CFU/g resulting in 0.15-0.5 log cycle reductions of microbial load.

The high viscosity of vegetable oils leads to problem in pumping and spray characteristics. The inefficient mixing of vegetable oils with air contributes to incomplete combustion. The best way to use vegetable oils as fuel in compression ignition (CI) engines is to convert it into biodiesel. Biodiesel is a methyl or ethyl ester of fatty acids made from vegetable oils (both edible and non-edible) and animal fat. The main resources for biodiesel production can be non-edible oils obtained from plant species such as Pongamia pinnata (Honge oil), Jatropha curcas (Ratanjyot), Hevea brasiliensis (Rubber) and Calophyllum inophyllum (Nagchampa). Biodiesel can be used in its pure form or can be blended with diesel to form different blends. It can be used in CI engines with very little or no engine modifications. This is because it has properties similar to mineral diesel. This paper presents the results of investigations carried out on a single-cylinder, four-stroke, direct-injection, CI engine operated with methyl esters of Honge oil, Jatropha oil and sesame oil. Comparative measures of brake thermal efficiency, smoke opacity, HC, CO, NO{sub X}, ignition delay, combustion duration and heat release rates have been presented and discussed. Engine performance in terms of higher brake thermal efficiency and lower emissions (HC, CO, NO{sub X}) with sesame oil methyl ester operation was observed compared to methyl esters of Honge and Jatropha oil operation.

The sesame (Sesamum indicum L.) germplasm, comprising of 105 accessions was characterized for total seed storage proteins using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The germplasm was collected from diverse agro-ecological regions of Pakistan. To our information, no studies have yet been carried out in Pakistan on the genetic evaluation of sesame genotypes based on total seed protein. Total seed proteins were electrophoretically separated on 12% polyacrylamide gels by standard protocols. A total of 20 polypeptide bands were observed, of which 14 (70%) were polymorphic and 6 (30%) were monomorphic, with molecular weight ranging from 13.5 to 100 kDa. Six bands i.e., 7, 11, 12, 15, 16 and 18 were common in all genotypes. Similarity coefficients varied fro m 0.50 to 1.00. The dendrogram based on dissimilarity matrix using unweighted pair group method with arithmetic averages (UPGMA) separated all sesame accessions into three main groups i.e., A, B, C, comprising 89, 14 and 2 genotypes, respectively. Overall a low to medium level of genetic variability was observed for SDS-PAGE (single dimension). As SDS-PAGE alone did not reveal high level of genetic variability, hence 2-D gel electrophoresis along with other advanced type DNA markers and more number of sesame accessions from all over the country are recommended for the future genetic evaluation. Our investigation will significantly support the classification, development, genetic evaluation and conservation of sesame germplasm in Pakistan. (author)

Full Text Available Abstract The consumption of white sesame has become a healthy option for those who are concerned about health and wish to reduce oxidative stress. The germination has been used an effective method to increase the nutrients availability and thus provide a better nutritional quality of these seeds. Due to the lack of researches about sesame germination the objective of this study was to evaluate the different times of germination on the chemical composition (moisture, fat, protein and ashes, the antioxidant capacity and the phenolic compounds of white sesame. The germination occurred inside a greenhouse with controlled temperature at 30 °C and the variables were analyzed in the times 0, 24, 36 and 48 hours of germination. The process increased the levels of moisture and reduced the levels of fat, protein and ashes. On the other hand, it also increased the antioxidant capacity by two methods and raised the quantity of total phenolic compounds. Based in the present study and in others similar works, it is possible to affirm that the germination process increase the white sesames’ antioxidant capacity, however further studies are needed to evaluate a better environmental condition of germination and others factors that may affect the composition.

Erbium-Doped Fiber Laser, EDF L, passively mode-locked via only Nonlinear Polarization Rotation, NPR, and via NPR with Semiconductor Saturable Absorber Mirror, SESAM, is studied. Self start single pulse train with pulse width of 114 fs and repetition rate (PRR) of 80 MHz has been obtained when 55 cm EDFL, passively mode-locked via NPR only. Inserting SESAM in EDFL cavity leads to shorten the pulse width up to 88 fs, increases the amplitude stability up to 96% and lower the phase noise jittering to around 26 fsec. Stable second harmonic self starting passively mode-locked EDFL with pulse width of 284 fs has also been observed only when SESAM was used in the cavity. Multi-pulsed system passively mode-locked via NPR for EDFL length of 80 cm with time difference between the successive multi-pulses ranged from few picoseconds to nanoseconds, has been observed. The time difference can be controlled by the polarizer controller and the half wave plate. Further controlling of the cavity polarization leads to developing the multiple mode locking pulses train to second harmonic mode-locking pulse train with PRR of 160MHz and pulse width of 156 fs. Three harmonic superposed trains of mode locked pulse have been achieved only when SESAM added to the cavity. (author)

Shatter resistance in sesame

International Nuclear Information System (INIS)

Langham, D.R.

2001-01-01

The majority of the world's sesame (probably over 99%) is shattering, and most of the harvest is manual. In a non-mechanized environment the last thing that farmers want is seed retention (''hold''). They want the seed to fall out as easily as possible. The amount of shattering desired is dependent on the method of harvest. By 1944 the first stage of mechanization was initiated. The indehiscent mutant found in 1943 showed in succeeding generations that it was controlled monogenically, and the homozygous recessive (id/id) gave indehiscence. Unfortunately, the id allele had pleiotropic effects including cupped leaves, twisted stems, short seed pods, semi-sterility, and low yield. Improvements in shatter resistance are relative within a specific program. For example, Sesaco has improved its shatter resistance each year, and still for the USA methods of harvest, further improvements are necessary to allow for better retention in adverse weather. This paper presents a methodology for quantifying shatter resistance so researchers can compare levels of shatter resistance between programs. (author)

Application of rhizospheric fungi is an effective and environmentally friendly method of improving plant growth and controlling many plant diseases. The current study was aimed to identify phytohormone-producing fungi from soil, to understand their roles in sesame plant growth, and to control Fusarium disease. Three predominant fungi (PNF1, PNF2, and PNF3) isolated from the rhizospheric soil of peanut plants were screened for their growth-promoting efficiency on sesame seedlings. Among these isolates, PNF2 significantly increased the shoot length and fresh weight of seedlings compared with controls. Analysis of the fungal culture filtrate showed a higher concentration of indole acetic acid in PNF2 than in the other isolates. PNF2 was identified as Penicillium sp. on the basis of phylogenetic analysis of ITS sequence similarity. The in vitro biocontrol activity of Penicillium sp. against Fusarium sp. was exhibited by a 49% inhibition of mycelial growth in a dual culture bioassay and by hyphal injuries as observed by scanning electron microscopy. In addition, greenhouse experiments revealed that Fusarium inhibited growth in sesame plants by damaging lipid membranes and reducing protein content. Co-cultivation with Penicillium sp. mitigated Fusarium-induced oxidative stress in sesame plants by limiting membrane lipid peroxidation, and by increasing the protein concentration, levels of antioxidants such as total polyphenols, and peroxidase and polyphenoloxidase activities. Thus, our findings suggest that Penicillium sp. is a potent plant growthpromoting fungus that has the ability to ameliorate damage caused by Fusarium infection in sesame cultivation.

Full Text Available Caffeine is a methylxanthine typically found in the Coffee Arabica L plant. Generally, caffeine is well-known as a orally administered mild stimulant of the central nervous system. However, for cosmetic purpose, caffeine is an active compound ingredient, at 7% concentration, in several anticellulite products. The efficiency of this mode of delivery is not fully understood. Hence, the aim of the study was to ascertain the effectiveness of particular carriers to release this ingredient. In so doing, we prepared six creams based upon different oils (Sesame oil, Rice oil, Walnut oil, Coconut oil, Sweet almond oil and Jojoba oil, containing 5% of caffeine, and compared the release of the substance from the obtained preparations. Initially, all of the creams were subjected to a variety of physical tests, among these being for slippage and spreadability. Furthermore, their rheological properties were evaluated. Subsequently, the creams were tested for caffeine release. In the slippage and spreadability tests, the coconut oil-based cream was revealed as having the best parameters. However, the rheological tests showed that all of the preparations had the pseudoplastic character of flowing according to the Ostwald de Waele power law model. The power low index (n for all the preparations was from 0.2467-0.3179 at 20°C and 0.2821-0.3754 at 32°C. At 20°C, the Sesame oil-, Walnut oil-, Sweet almond oil- and Jojoba oil-based creams were thixotropic, but at 32°C, thixotropy appeared only in the Walnut oil-based creams.

Full Text Available This article carried out the extraction of sesame oil by using three extraction techniques: supercritical fluid extraction (SFE, Soxhlet and sequential extraction. The SFE was performed using supercritical carbon dioxide (SC-CO2 as solvent and ethanol as cosolvent. Tests were performed at 20 MPa, 35ºC and a flow rate of 2.5 g CO2/min with a total extraction time of 210 minutes. The Soxhlet extraction was performed for 8 hours, using petroleum ether and ethanol as solvents, until the exhaustion of the oil contained in the seeds. The sequential extraction used ethyl ether, ethanol and water as solvents. The Soxhlet extraction was the most effective (58.93%, while the SFE technique obtained 26.47% as the best result. The antioxidant activity (AA was determined by the β-carotene/linoleic acid system, with good oxidation inhibition percentages (29.32-83.49% for all the extracts. The main fatty acids (FA in sesame oil were oleic and linoleic acids.

Full Text Available To study the nature and magnitude of gene effects for yield and its components in sesame (Sesamum indicum L. we carried out generation mean analysis using the following four crosses of different sesame cultivars: VS 9510 x Co1; NIC 7907 x TMV 3; Cianno 13/10x VRI 1; and Si 1115/1 x TMV 3. The P1, P2, F1, F2, BC1 and BC2 of these generations were studied for seven quantitative traits. The analysis showed the presence of additive, dominance and epistatic gene interactions. The additive dominance model was adequate for plant height in the NIC 7907 x TMV3 and Si 1115/1x TMV 3 crosses and for capsule length in the VS 9510 x Co1, NIC 7907 x TMV 3 and Si 1115/1 x TMV 3 crosses. An epistatic digenic model was assumed for the remaining crosses. Duplicate-type epistasis played a greater role than complementary epistasis. The study revealed the importance of both additive and non-additive types of gene action for all the traits studied.

The 2014 High School Teacher Programme (HST) is well under way, and this year it has a distinct Middle Eastern flavour, with eight teachers from the region among the 54 taking part. Established in the late 1990s, HST is a three-week residential programme in English designed to give teachers a taste of frontier research and promote the teaching of modern physics in high schools. Along with the more than 30 other teacher schools given in the native language of the participants, HST aims to help teachers bring modern physics to the classroom and motivate their students to study science at upper secondary school and university. As part of the HST programme, teachers form working groups to develop lessons based on CERN science. This year, however, with eight teachers coming from Israel, Palestine, Iran and Jordan, all of which are members of SESAME, the international laboratory for Synchrotron-Light for Experimental Science Applications in the Middle East, one group is working on a dif...

In response to increased concerns about spice safety, the United States Food and Drug Administration (FDA) initiated research to characterize the prevalence and levels of Salmonella in imported spices. 299 imported dried capsicum shipments and 233 imported sesame seed shipments offered for entry to the United States were sampled. Observed Salmonella shipment prevalence was 3.3% (1500 g examined; 95% CI 1.6-6.1%) for capsicum and 9.9% (1500 g; 95% Confidence Interval (CI) 6.3-14%) for sesame seed. Within shipment contamination was not inconsistent with a Poisson distribution. Shipment mean Salmonella level estimates among contaminated shipments ranged from 6 × 10(-4) to 0.09 (capsicum) or 6 × 10(-4) to 0.04 (sesame seed) MPN/g. A gamma-Poisson model provided the best fit to observed data for both imported shipments of capsicum and imported shipments of sesame seed sampled in this study among the six parametric models considered. Shipment mean levels of Salmonella vary widely between shipments; many contaminated shipments contain low levels of contamination. Examination of sampling plan efficacy for identifying contaminated spice shipments from these distributions indicates that sample size of spice examined is critical. Sampling protocols examining 25 g samples are predicted to be able to identify a small fraction of contaminated shipments of imported capsicum or sesame seeds. Published by Elsevier Ltd.

Phlebitis is the most common complication associated with peripheral intravenous infusion of amiodarone. The purpose of this study is to determine the effects of sesame oil on the prevention of amiodarone-induced phlebitis. This is a double-blind randomized controlled trial. Thirty-six patients hospitalized in a coronary care unit were randomly allocated into two groups using a convenience sampling method. Following peripheral intravenous cannulation, five drops of pure sesame oil were applied to the skin within a 10 cm radius of the infusion site prior to the administration of amiodarone in the intervention group. Sesame oil was rubbed on the skin at the infusion site every 6 h in the 24-h period of amiodarone infusion. In the control group, liquid paraffin, used as a placebo, was rubbed on the skin at the infusion site of amiodarone. Both groups were monitored for the development of phlebitis and its degree within the 24-h period of amiodarone infusion as well as 6 h after its administration. The incidence of phlebitis was confirmed and recorded by an assessor who was blind to the two groups. Data were analyzed using Statistical Package for Social Science (SPSS) version 18, and descriptive and inferential statistics such as Chi-square test, Kaplan-Meier, Hazard ratio, independent t-test, and Fisher's exact test. There was a statistically significant difference between the two groups in their catheter survival after 30 h and 10 min (P phlebitis, while 16.7% and 22.2% of the patients manifested signs of grade 2 and 3 phlebitis, respectively. In the control group, 22.2% of the patients showed no signs of phlebitis, while 5.6%, 27.8%, and 44.4% of the patients exhibited signs of grade 2, 3, and 4 phlebitis, respectively. The statistical analysis showed significant differences in the degree of phlebitis (P = 0.006) and the onset of phlebitis development (P phlebitis.

Full Text Available ABSTRACT The sesame crop has stood out due to the high nutritional content of its seeds, in addition to being able to be cultivated in the tropical and subtropical regions such as Northeast Brazil. Thus, it is necessary to identify the physiological, biochemical and productive changes related to the tolerance to stress. Objective of this study was to evaluate the physiological, biochemical and productive aspects of sesame genotypes as a function of different rates of water replenishment. The experiment was carried out at the Embrapa Cotton Experimental Unit, located in the municipality of Barbalha-CE, Brazil, under field conditions. The experiment was carried out in a randomized complete block design, with treatments in a factorial scheme (4 × 6, corresponding to four irrigation depths (40, 70, 100 and 130% ETo and six sesame genotypes (G1 = T3-EGSGO3; G2 = T7-EGSGO7; G3 = T5-EGSGO5; G4 = T2-EGSGO2; G5 = T6-EGSGO6; G6 = T4-EGSG04, with three replicates. Data corresponding to the following variables were collected: leaf area, photosynthetic pigments, relative water content in leaf, electrolyte leakage, catalase, peroxidase, yield and oil content. The genotypes did not differ statistically and there were differences in the variables between the water replacement rates. Increments in growth and, consequently, in production, enzymatic activity, oil content and maximum production potential were observed with water depths between 75 and 90% ETo. Contents of chlorophyll a and b, total chlorophyll and carotenoids, were increased with the application of 80% ETo.

Full Text Available Ascertaining the authenticity of the unrefined sesame oil presents an ongoing challenge. Here, the determination of 2-propenal was performed by headspace solid-phase microextraction (HS-SPME under mild temperature coupled to gas chromatography with time-of-flight mass spectrometry, enabling the detection of adulteration of unrefined sesame oil with refined corn or soybean oil. Employing this coupled technique, 2-propenal was detected in all tested refined corn and soybean oils but not in any of the tested unrefined sesame oil samples. Using response surface methodology, the optimum extraction temperature, equilibrium time, and extraction time for the HS-SPME analysis of 2-propenal using carboxen/polydimethylsiloxane fiber were determined to be 55°C, 15 min, and 15 min, respectively, for refined corn oil and 55°C, 25 min, and 15 min, respectively, for refined soybean oil. Under these optimized conditions, the adulteration of unrefined sesame oil with refined corn or soybean oils (1–5% was successfully detected. The detection and quantification limits of 2-propenal were found to be in the range of 0.008–0.010 and 0.023–0.031 µg mL−1, respectively. The overall results demonstrate the potential of this novel method for the authentication of unrefined sesame oil.

Seeds of five sesame cultivars: T-85, Serra, EM-14, Anyana and S were irradiated with 0, 200, 300, 400, 600 and 800 Gy doses of gamma rays. Irradiated seeds together with their controls were planted in 1995 to produce M 1 plants. Records were taken on germination percentage after four days and three weeks, and vigour also after three weeks of germination. Much decline in growth was recorded from the doses of 600 and 800 Gy. Five capsules/plant from each variety per dose were harvested to grow M 2 progenies. 276 single plants were selected out of 2,636 plants from all the treated varieties. Out of 276 plants selected and planted, 30 progeny rows of those single plants were further selected to be tested in a preliminary yield trial. From five varieties about 7,000 seeds per dose per variety have again been irradiated with 300, 400, 500, and 600 Gy gamma rays. (author)

SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) is a UNESCO-sponsored project that is constructing an international research laboratory, closely modeled on CERN, in Jordan (www.sesame.org.jo). Ten Members of the governing Council (Bahrain, Cyprus, Egypt, Iran, Iraq, Israel, Jordan, Pakistan, Palestinian Authority, and Turkey) have responsibility for the project, led by Herwig Schopper, Council President since 1999. In late 2008 Chris Llewellyn-Smith will become Council President. SESAME was initiated by a gift from Germany of the decommissioned BESSY I facility. The BESSY I 0.8 GeV injector is now being installed in the recently completed building, funded by Jordan, as components are procured for a new 133 m circumference, 2.5 GeV third-generation storage ring with 12 locations for insertion devices. Beam line equipment has been provided by laboratories in France, UK, and US. Support also comes from EU, IAEA, ICTP, Japan Society for the Promotion of Science, the US Department of Energy and State Department, and laboratories around the world. The broad scientific program includes biomedical, environmental, and archaeological programs particularly relevant to the Middle East. Five scientific workshops and six annual Users' meetings have brought together several hundred scientists from the region, along with researchers from around the world. Training programs have enabled about 100 scientists from the region to work at synchrotron radiation laboratories. These activities have already had significant impact on science and society in the Middle East, for example leading to collaborations between scientists from countries that are not particularly friendly with each other, and to national planning emphasizing synchrotron radiation research. When research starts in 2011 this impact will grow as graduate students are trained in the region in many scientific disciplines, and scientists working abroad are attracted to return.
Establishment probability in newly founded populations

Gusset Markus

2012-06-01

Full Text Available Abstract Background Establishment success in newly founded populations relies on reaching the established phase, which is defined by characteristic fluctuations of the population’s state variables. Stochastic population models can be used to quantify the establishment probability of newly founded populations; however, so far no simple but robust method for doing so existed. To determine a critical initial number of individuals that need to be released to reach the established phase, we used a novel application of the “Wissel plot”, where –ln(1 – P0(t is plotted against time t. This plot is based on the equation P0t=1–c1e–ω1t, which relates the probability of extinction by time t, P0(t, to two constants: c1 describes the probability of a newly founded population to reach the established phase, whereas ω1 describes the population’s probability of extinction per short time interval once established. Results For illustration, we applied the method to a previously developed stochastic population model of the endangered African wild dog (Lycaon pictus. A newly founded population reaches the established phase if the intercept of the (extrapolated linear parts of the “Wissel plot” with the y-axis, which is –ln(c1, is negative. For wild dogs in our model, this is the case if a critical initial number of four packs, consisting of eight individuals each, are released. Conclusions The method we present to quantify the establishment probability of newly founded populations is generic and inferences thus are transferable to other systems across the field of conservation biology. In contrast to other methods, our approach disaggregates the components of a population’s viability by distinguishing establishment from persistence.

Full Text Available BACKGROUND AND OBJECTIVE: Sleep disorders in nurses due to rotational shiftwork and diversity of the working time are highly prevalent, which can be improved by aromatherapy. In this study, we aimed to evaluate the effect of aromatherapy with lavender essential oil on sleep quality of nurses covered by social security. METHODS: This clinical trial study was conducted in 78 nurses randomly divided into two groups of lavender and sesame oil (placebo. The participants used lavender essential oil and sesame oil for two hours in early hours of their shift for four weeks. Pittsburgh Sleep Quality Index (PSQI was employed to evaluate sleep quality of both groups pre-intervention and at the end of the second and fourth weeks of the intervention (IRCT: 201407176342N4. FINDINGS: According to the results, mean ages of the lavender and placebo groups were 34.87±4.85 and 36.49±5.38 years, respectively. Moreover, there was no significant difference between the two groups regarding anthropometric variables (i.e., the mean height, weight, and overtime working hours. In addition, the groups were homogenous in terms of gender, marital status, work shift, department, and educational level. The results indicated no significant difference between the lavender and sesame groups regarding the mean scores of sleep quality (7.79±3.78 vs. 7.44±4.24; this mean was not significantly different between the groups at the end of the second and fourth weeks, as well. CONCLUSION: In this study, lavender essential oil had no significant impact on sleep quality of the nurses

Full Text Available In order to control seed-borne diseases, we obtained extracts from commercial fermented food products of Kimchi, Gochujang, Doenjang, Ganjang and Makgeolli and their suppressive effects against seed-borne diseases were studied. In addition, the suppressive effects of bacterial strains isolated from the fermented foods were screened in vitro and in vivo. Among fifty food extracts, twenty food-extracts suppressed more than 92% incidence of seedling rots in vitro and seven food extracts increased 58.3-66.8% of healthy seedling in the greenhouse. Among 218 isolates from the fermented foods, 29 isolates showing high antifungal activity against seven seed-borne fungal pathogens were selected. Among 29 isolates, 13 isolates significantly reduced seedling rot and increased healthy seedlings. Sixteen isolates with high antifungal activity and suppressive effect against sesame seedling rots were identified by 16S rRNA sequencing. Fourteen of sixteen isolates were identified as Bacillus spp. and the other two isolates from Makgeolli were identified as Saccharomyces cerevisiae. It was confirmed that B. amyloliquifaciens was majority in the effective bacterial population of Korean fermented foods. In addition, when the bioformulations of the two selected effective microorganisms, B. amyloliquifacien Gcj2-1 and B. amyloliquifacien Gcj3-1, were prepared in powder forms using bentonite, kaolin, talc and zeolite, talc- and kaolin-bioformulation showed high control efficacy against sesame seed-borne disease, followed by zeolite-bioformulation. Meanwhile control efficacy of each bentonite-bioformulation of B. amyloliquifacien Gcj2-1 and B. amyloliquifacien Gcj3-1 was lower than that of bacterial suspension of them. It was found that the selected effective microorganisms from Korean fermented foods were effective for controlling seed-borne diseases of sesame in vitro and in the greenhouse. We think that Korean fermented food extracts and useful microorganisms

Eleven odor-active thiols, namely, 2-methyl-1-propene-1-thiol, (Z)-3-methyl-1-butene-1-thiol, (E)-3-methyl-1-butene-1-thiol, (Z)-2-methyl-1-butene-1-thiol, (E)-2-methyl-1-butene-1-thiol, 2-methyl-3-furanthiol, 3-mercapto-2-pentanone, 2-mercapto-3-pentanone, 4-mercapto-3-hexanone, 3-mercapto-3-methylbutyl formate, and 2-methyl-3-thiophenethiol, recently identified in an extract prepared from white sesame seeds, were quantitated in sesame using stable isotope dilution analyses. For that purpose, the following deuterium-labeled compounds were synthesized and used as internal standards in the quantitation assays: [2H6]-2-methyl-1-propene-1-thiol, [2H3]-(E)- and [2H3]-(Z)-2-methyl-1-butene-1-thiol, [2H3]-2-methyl-3-furanthiol, [2H2]-3-mercapto-2-pentanone, [2H3]-4-mercapto-3-hexanone, [2H6]-3-mercapto-3-methylbutyl formate, and [2H3]-2-methyl-3-thiophenethiol. On the basis of the results obtained, odor activity values (OAVs) were calculated as ratio of the concentration and odor threshold of the individual compounds in cooking oil. According to their high OAVs, particularly the 3-methyl-1-butene-1-thiols (OAV: 2400) and the 2-methyl-1-butene-1-thiols (OAV: 960) were identified as the most odor-active compounds in pan-roasted white sesame seeds. These compounds were therefore suggested to be mainly responsible for the characteristic but rather unstable sulfury aroma of freshly pan-roasted white sesame seeds.

In this context, this study aimed to evaluate the emergence, growth and production of sesame, cultivar CNPA G3, irrigated with saline water and fertilized with N of different carrier proportions by the ratio of nitrate and ammonium ( NO 3 - - N and NH 4 + - N in an experiment conducted in lysimeters arranged in a greenhouse in the municipality of Campina Grande - PB, Brazil. The treatments were distributed into randomized blocks using a 5 × 5 factorial scheme relative to levels of irrigation water salinity (ECw; 0.6, 1.2, 1.8, 2.4 and 3.0 dS m - 1 and five proportions of NO 3 - - N/NH 4 + - N (200/0; 150/50; 100/100; 50/150 and 0/200 mg of N kg - 1 , with three replicates. The increase in ECw compromised the emergence, growth and production of sesame, cultivar CNPA G3, and the production components were the most sensitive variables. The highest growth in diameter was obtained with the proportion of 200/0 mg kg - 1 of NO 3 - - N /NH 4 + - N . An ECw level of 3.0 dS m - 1 and fertilization with 0/200 mg kg - 1 of NO 3 - - N /NH 4 + - N promoted deleterious effects on the total mass of sesame fruits and mass of seeds. The interaction between water salinity levels and NO 3 - /NH 4 + proportions significantly affected the number of leaves (at 50 and 70 days after sowing, the total mass of fruits and the mass of seeds.

Full Text Available Insufficient genetic variability is one of the major problems of plant breeding programmes, especially in sesame. Gamma radiation has been reported to be very effective in creating genetic variability in plants. Three varieties of Nigerian sesame were assessed for spectrum and frequency of mutation induced by Gamma radiations in M1 and M2 generations. The varieties (NCRIBEN-04E, NCRIBEN-01M and NCRIBEN-03L were treated with four different doses of gamma rays (250, 350, 450 and 550 Gy. The treated and untreated seeds (control were sown in planting bags (under field condition to raise M1 plants. Four treatments: V1D5, V2D3, V3D2 and V3D4 (from M1 plants were selected and bulked to obtain M2 populations. The results of M1 revealed four mutant fruit traits: multicarpellate capsule, multiple capsule per leaf axil, indehiscent capsule and terminal capsules. The highest frequencies of the traits in M1 generation were 2.50×10-2, 9.17×10-2, 1.67×10-2and3.33×10-2 respectively. The highest branching (7 was from NCRIBEN-01M, while the least (2 was from NCRIBEN-04E. The M2 plants were grouped into eight M2 lines. The dose range (250-550 Gy was proved to be effective in inducing viable mutations in sesame.

Full Text Available ABSTRACT The study aimed to evaluate the effects of irrigation with saline water and fertilization with nitrate (NO3--N and ammonium (NH4+-N ratios on growth, flowering, water consumption and water use efficiency of the sesame cv. CNPA G3. The treatments were distributed in randomized blocks in a 5 x 5 factorial with three replicates, referring to five levels of electrical conductivity of the irrigation water - ECw (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1 and nitrate (NO3--N and ammonium (NH4+-N (200/0, 150/50, 100/100, 50/150, 0/200 mg kg-1 ratios. Irrigation with saline water above 0.6 dS m-1 inhibited the growth, delayed flowering and promoted early maturation of capsules of sesame, cv. CNPA G3. The proportion of 0/200 mg kg-1 of NO3--N/NH4+-N promoted the greatest increase relative to stem diameter and height of sesame plants. Water consumption decreases with increasing ECw and was significantly lower in plants fertilized with the proportion of 0/200 of NO3--N/NH4+-N. The interaction between ECw levels and ammonium/nitrate proportions significantly affect water use efficiency, and the highest value was obtained with ECw of 0.6 dS m-1 and fertilization with 150:50 mg kg-1 of NO3--N and NH4+-N.

Nutritional intervention with antioxidants rich foods has been considered a strategy to minimize the effects of overtraining in athletes. This experimental, randomized, and placebo-controlled study evaluated the effects of consumption of sesame ( Sesamum indicum L.) on muscle damage markers, oxidative stress, systemic inflammation, and aerobic performance in male semi-professional soccer players. Twenty athletes were randomly assigned to groups that received 40 g (two tablespoons) per day of sesame or a placebo during 28 days of regular training (exposed to routine training that includes loads of heavy training in the final half of the season). Before and after intervention, creatine kinase (CK), lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD), C-reactive protein (hs-CRP), and aerobic capacity were evaluated. Before intervention, a physiologic imbalance was noted in both groups related to CK and LDH levels. Sesame intake caused a reduction of CK (19%, p < 0.05), LDH (37%, p < 0.05), MDA (55%, p < 0.05) and hs-CRP (53%, p < 0.05) and increased SOD (14%, p < 0.05), vitamin A (25%, p < 0.05), and vitamin E (65%, p < 0.05) in the experimental group. These phenomena were accompanied by increased aerobic capacity (17%, p < 0.05). The placebo group showed an increase in CK (5%, p < 0.05) and no significant change in LDH, SOD or vitamin A. MDA levels decreased (21%, p < 0.05) and vitamin E increased (14%, p < 0.05) in the placebo group, but to a much lesser extent than in the experimental group. These results show that sesame consumption may reduce muscle damage and oxidative stress while improving the aerobic capacity in soccer players.

The thermoluminescence (Tl) emission of minerals isolated from Mexican and Indian sesame seeds appear as a good tool to discern between irradiated and non-irradiated samples. According to the X-ray diffraction and environmental scanning microscope, the adhered dust in both samples is mainly composed by different amounts of quartz and feldspars. These mineral phases exhibit (i) enough sensitivity to ionizing radiation inducing good Tl intensity, (ii) high stability of the Tl signal during the storage of the material (i.e. low fading) and (iii) are thermally and chemically stable. Blind tests performed under laboratory conditions, but simulating industrial preservation processes (similar temperature and moisture, and presence of white light), allows to distinguish between 1 KGy gamma-irradiated and non-irradiated samples even 11000 hours (15 months) after the irradiation proceeding.

Sesame varieties/genotypes showed a good response to radiation with gamma rays and treatments with EMS. In M 1 both gamma rays and EMS influenced germination, seedling height, survival of plants and pollen fertility/sterility, producing deleterious effects on these characters. Compared to black seeded genotypes, white seeded ones are more susceptible to radiation. Both gamma rays and EMS produced various types of morphological variations in M 2 generation. These were dwarf plant mutants, mottled and fleshy leaved mutants (sterile), fasciated stem, flower colour, altered phyllotaxy, early, uniculm, capsule size variations, multiple capsule/leaf axil, seed coat colour variations, indehiscent and semi-indehiscent type mutants. Moreover, studies on quantitative characters including seed yield revealed the induction of mutants in both positive and negative directions for such traits which made a good scope of selection of desirable mutants in M 2 generation. Mutants selected in M 2 were raised in M 3 in plant to progeny rows and further selection was made. Compared to the M 2 generation, the range of family means became narrower in M 3 which indicated the effectiveness of selection in the M 2 . True breeding lines isolated in M 3 generation have given potentially higher seed and oil yield in a preliminary yield trial in M 4 compared to source. Six promising mutant lines were evaluated in M 4 , M 5 , M 6 , M 7 and M 8 generations for seed yield and other agronomic parameters at various locations of Bangladesh under variable environments. Mutants SM5, SM7 have produced significantly higher seed yields at all locations with 50-52% oil content compared to 40-44% oil content in the source varieties. Some mutants were tolerant to stem rot and sesame mosaic in most of the locations. The increased yield was due to higher number of capsules/leaf axil, longer capsules with continuous bearing and increased number of seeds/capsule. It was also observed that white seeded mutants

Full Text Available Introduction Sesame (Sesamum indicum plays an important role in human health because of its high oil capacity (47 - 52%.. Arbuscular mycorrhizal symbiosis protects host plants against the detrimental effects of drought stress through mechanisms of drought avoidance. Strategies of drought avoidance in mycorrhizal plants rely on the ability to maintain an adequate hydration status on the level of whole plants as characterized by relative water content. So the aim of current study was to evaluate the symbiosis effect of two different species of mycorrhizae fungi on yield and physiological characteristics of sesame landraces under different drought stress levels in Urmia. Materials and Methods This experiment was conducted in 2014-2015 by using factorial split plot based on randomized complete block design with three replications in the research field of Urmia agricultural high school with 12 Km distance from Urmia. The main plot factor was consisted of different irrigation levels: normal irrigation (irrigation after 70 mm evaporation of crop (ETC, moderate drought stress (irrigation after 90 mm evaporation of crop (ETC and severe drought stress (irrigation after 110 mm evaporation of crop (ETC.

Formerly incarcerated persons (FIPs) face a disproportionate risk of death and serious illness in the immediate post-release period. Therefore, it is a critical time to initiate community-based care for chronic illnesses and behavioural disorders. Little is known about the unique transitional health and social support needs of FIPs in Louisiana, which has the highest incarceration rate in the world. As the average age of prisoners in the United States rises, the release of older prisoners with chronic conditions will become increasingly common. The aim of this study was to explore the healthcare experiences of FIPs in Louisiana in order to inform delivery of services tailored to this population. This research was done in partnership with a community organisation that advocates for restoration of voting rights to FIPs and helps newly released individuals transition back into society. This organisation identified FIPs in the Greater New Orleans area, and from January to May 2015, we conducted 24 semi-structured, in-person, audio-recorded interviews at the community organisation's transitional living facility. The interviews assessed FIPs' experiences with and barriers to receiving healthcare during and after incarceration. These discussions also explored FIPs' desires for services and attitudes towards health and healthcare. Interviews were transcribed and independently coded by two researchers. Interviewees reported negative experiences with healthcare during incarceration, and limited health guidance during the pre-release process. Post-release concerns included lack of insurance, difficulty accessing care and medication, and interest in learning about healthy lifestyles. Results suggest a need for a formalised system of transitional healthcare for FIPs. Findings are being used to inform a pilot transitional care clinic in New Orleans, Louisiana. © 2017 John Wiley & Sons Ltd.

Full Text Available This study presents a drug delivery system of poly (Ɛ-caprolactone (PCL ribbons to optimize the pharmaceutical action of tramadol for the first time according to our knowledge. PCL ribbons were fabricated and loaded with tramadol HCl. Ribbons were prepared by slip casting technique and coated with dipping technique with β-cyclodextrin. The chemical integrity and surface morphology of the ribbons were confirmed using FTIR and SEM coupled with EDX. In addition, thermodynamic behavior of the fabricated ribbons was investigated using DSC/TGA. Tramadol loading into PCL ribbons, biodegradation of ribbons and tramadol release kinetics were studied in PBS.The results revealed that the formulated composition did not affect the chemical integrity of the drug. Furthermore, SEM/EDX confirmed the inclusion of tramadol into the PCL matrix in homogenous distribution pattern without any observation of porous structure. The particle size of loaded tramadol was found to be in the range of (2–4 nm. The formulated composition did not affect the chemical integrity of the drug and should be further investigated for bioavailability. Tramadol exhibited controlled release behavior from PCL ribbons up to 45 days governed mainly by diffusion mechanism. The fabricated ribbons have a great potentiality to be implemented in the long term subcutaneous delivery of tramadol.

This document summarizes the shock and release response of Epon 828 measured in the dynamic impact experiment 2s-905. Experimentally, a thin Kel-F impactor backed by a low impedance foam impacted an Epon 828 target with embedded electromagnetic gauges. Computationally, a one dimensional simulation of the impact event was performed, and tracer particles were located at the corresponding electromagnetic gauge locations. The experimental configuration was such that the Epon 828 target was initially shocked, and then allowed to release from the high-pressure state. Comparisons of the experimental gauge and computational tracer data were made to assess the performance of equation of state (EOS) 7603, a SESAME EOS for Epon 828, on and off the principal shock Hugoniot. Results indicate that while EOS 7603 can capture the Hugoniot response to better that 1%, while the sound speeds at pressure are under-predicted by 6 - 7%.

Wongyai, W.; Saengkaewsook, W.; Veerawudh, J.

2001-01-01

Improvement of non-shattering capsule by using gamma rays and EMS in the Kasetsart University Sesame Breeding Project has been carried out since November 1994. Seed treatments with gamma rays (500 Gy) and EMS (0.5 and 1.0%, 4 hrs) were used. Growth characteristics, delayed shattering and shatter resistance of capsule were investigated in M 2 through M 8 lines. The seed yield of thirty promising M 7 lines was evaluated in April 1997 at Suwan Farm, Pakchong, Nakorn Ratchasima. Most of the tested lines gave higher seed yields than the check variety, MK 60. M 6026 gave the highest seed yield (1,477 kg/ha). All the tested mutant lines had a longer period of growth during flowering (GF). However, three promising lines had a shorter flowering period (FP) and a degree of stem termination (DST) when they were planted both in April and August 1997. Based on the criteria of determinate growth studied, these mutant lines would be classified as having a determinate growth habit. Delayed shattering and shatter resistant capsule were obtained. It is noted that the promising mutant lines were obtained from EMS treatment. Thus, the study of these mutant lines revealed that the improvement of sesame by mutation breeding for reduced seed losses before or during the harvest can be successful. (author)

gergelim como o mercado internacional. Atualmente, mais de 60% do consumo de gergelim no Brasil é importado. = - The sesame (Sesamum indicum L. is one of the ﬁ rst species domesticated by humans, being nowadays one of the top ten oil plant in the world. Planted in an area around eight million hectares, the main product is the sesame seed. High nutritional value for food, and medicinal properties of sesame seeds are sources of vitamins (B vitamins, rich in minerals (calcium, phosphorus, magnesium, sodium, zinc and selenium, oil (50% composed of unsaturated fatty acids (oleic (40% and linoleic (41% and antioxidants such as sesamin, the sesamoline the tocopherol that print resistance to rancidity. Sesame presscake has important amino acids such as methionine, cystine, arginine and leucine becoming an excellent source of protein (39%. The sesame is easy to grow and has fast cycle cultivars, between 90-130 days. Information contained in this technical note can contribute to agribusiness and the small scale production, exploring the potential of sesame in a big picture of economic activity, especially for the semiarid Northeast, or as a “culture of off season in terms of the Brazilian Cerrado. Aimed to highlight the following technologies adapted to the cultivation of sesame: different planters, the importance of synchronized sampling, different ways to track and drying. It is shown that the mere introduction of the mower-knotters yield (2 ha men-1to perform the cutting of plants at harvest time can signiﬁ cantly increase the area planted to sesame in Brazil, even with the dehiscent sesame cultivars planted. The vertical integration of production of sesame is the dependence of changes in dietary and social habits of the population, because the domestic market is limited and for this reason can not appreciate both the quality of sesame as the international market. Currently, over 60% of consumption of sesame seeds in Brazil is imported.

Full Text Available Sesame is an important crop in West and Central Africa playing a role of an alternative cash crop for smallholders. However, sesame productivity is highly impaired by drought. This study aimed at identifying some drought-resistant genotypes and efficient screening traits in large sesame germplasm. Ten genotypes were examined based on 21 biochemical, physiological, agromorphological and seed quality traits under three weeks of water stress. A high variability for drought resistance was observed among the genotypes. The genotypes WC17, WC18 and WC14 were drought resistant, WC12, WC13, WC06 and WC03 were moderately drought resistant while, WC02, WC10 and WC08 were drought sensitive, based on principal component analysis. The resistant genotypes exhibited both avoidance and tolerance features including increase of the root system, reduced water loss, highest activity of antioxidative enzymes and accumulation of proline. They produced higher biomass and had higher ability to maintain seed quality under drought stress compared with the sensitive genotypes. Strong accumulation (~200% ratio stress/control of biochemical markers including superoxide dismutase, ascorbate peroxidase, catalase and proline could be regarded as an important indicator for selecting drought resistant genotypes. This study represents a reference for future research towards developing new varieties with improved drought resistance in West and Central Africa.

Full Text Available In many crops, incorrect management of nitrogen and water is one of the most important factors in the resources productivity such as water and nitrogen. In order to evaluate the effects of different nitrogen levels (zero, 50, 100 and 150 kg ha-1 and irrigation application rates (100, 75 and 50% of water requirement per species on corn, sesame and sugar beet, three separate experiments was conducted in Agricultural Research Station of Ferdowsi University of Mashhad, Iran, in 2009-2010 growing season. Three separate experiments were arranged by strip plots in randomized complete block design, with three replications. The results showed that effect of irrigation application rates on biological yield and grain number per ear and interaction effects of water × nitrogen on plant height, 100 grain weight and grain yield of corn was significant. With decreasing irrigation over 25 % water requirements, the highest grain yield (4.93 ton ha-1 in corn observed by applying nitrogen equal to 50 kg.ha-1. In addition, the highest maize yield (9.41 ton.ha-1 in mentioned was obtained by supplying 100 % water requirements. Effects of Irrigation levels on plant height and the interaction effects of water × nitrogen on 1000 grain weight in sesame was significant. Under no water stress, the highest grain yield (1.22 ton ha-1 in sesame was obtained with applying 50kg nitrogen per ha. With supplying 75% water requirements plus 50 kg nitrogen per hactar, maximum yield of sesame (820 kg ha-1 was obtained. Results of this study indicated that interaction between studied factors had insignificant effect on economic and biological yield in sugar beet. With supplying 25% water requirements plus 50 kg nitrogen per ha, maximum yield of sugar beet (58.37 ton ha-1 was achieved. It seems that suitable nitrogen management can be considered as approach in optimize the water consuming.

We report self-starting femtosecond operation of a 127-MHz SESAM mode locked Cr:ZnSe laser around 2420 nm. A thulium doped double clad fiber laser at 1908 nm was used as the pumping source. In the normal dispersion regime, stable pulse pairs with constant phase differences in the multipulse regime were observed. The maximum output power was 342 mW with respect to incident pump power of 4.8 W and the corresponding slope efficiency was 10.4%. By inserting a piece of sapphire plate, dispersion compensation was achieved and the intra-cavity dispersion was moved to the anomalous regime. A maximum output power of 403 mW was obtained and the corresponding slope efficiency was 12.2%. Pulse width was measured to be 408 fs by a collinear autocorrelator using two-photon absorption in an InGaAs photodiode. The laser spectrum in multipulse operation showed a clear periodic modulation.

Station yield trial: Three high yielding mutants (8, 48, and EFM92) with better and stable performance were developed in our breeding programme and submitted for registration to the Agricultural Research Center (ARC), Egyptian Ministry of Agriculture and Land Reclamation. Multi-location yield trials indicated that mutant line EFM92 ranked first in all locations; significant yield increases recorded for it ranged from 14.7 to 74.0% over the check variety. Moreover, it was 15-20 days earlier than the check and/or other mutants. Mutant lines 8 and 48 produced higher seed yields than the check at two different locations. These mutants can probably be grown and produce more yield than the check variety at the low yielding environments. Seed quality assay: During 1996 and 1997, 15 promising lines of sesame including mutants and hybrid populations as well as the local variety were evaluated for seed protein, oil content and fatty acid composition. The protein content varied from 20.6 to 26.7%; hybrid population EXM90 gave the highest value. About 85% of the total fatty acids in the oil are unsaturated (oleic and linoleic) and 15% saturated, mainly palmitic and stearic. Linoleic acid ranged from 41.8 to 47.9%. Mutant lines 6, 9, and EFM92, which gave high oil content (54-55.5%) together with high linoleic acid values (45.2-47.8%), are recommended for breeding for seed oil quality. Heterosis, combining ability and type of gene action in sesame: A half diallel set of crosses involving seven parents was used to study heterosis and combining ability in the F 1 generation as well as the nature of gene action controlling seed yield and its contributing traits in both F 1 and F 2 in order to identify the most efficient breeding methods leading to rapid genetic improvement. The expressions of heterosis varied with the crosses and characters investigated. The maximal significant positive useful heterosis was observed for branches/plant (52.9%) followed by seed yield/plant (38

Full Text Available A colheita é uma das etapas mais importantes no rendimento final do sistema produtivo do gergelim, pois perdas de sementes de 50% ou mais podem ocorrer após a maturação completa, devido à deiscência das cápsulas. Dessa forma, objetivou-se no presente trabalho apresentar, por meio de uma revisão bibliográfica, as tecnologias recomendadas para a colheita do gergelim: corte das plantas, preparação e organização dos feixes, secagem, batedura, peneiração e ventilação dos grãos. Ressalta-se, ainda, que a comercialização do gergelim no Nordeste é bastante pulverizada e de difícil organização, principalmente por ser proveniente de pequenos agricultores, onde se concentra a maior parte da produção. Nessa situação, o ideal é que os agricultores se organizem via cooperativas e associações para fomentar o cultivo em comunidade visando um planejamento a priori para maior eficiência e rentabilidade da exploração do gergelim, principalmente pelo fato do consumo nacional apresentar-se superior a oferta do produto. Este trabalho também relata a verticalização da produção de gergelim e as suas qualidades na saúde e alimentação humana. = The harvest is one of the most important stages in the final yield of the production system of sesame, because seed losses of 50% or more might occur following maturation, due to dehiscence of the capsules. Thus, the aim of this study show was to review the literature relative to the recommended technologies for the harvesting of sesame: cutting plant, preparation and organization of the beams, drying, mixing, sifting and ventilation of the grain. It is also important to note that the marketing of sesame in the Northeast is highly dispersed and difficult to organized, primarily because it is obtained from small farmers, where most of the production is done. In this a situation, the ideal would be for farmers be organized through cooperatives and associations to promote community growth in

The complexes have been synthesized from Cu (II) soaps of groundnut (Arachis hypogaea) and sesame (Sesamum indicum) oils, with ligand containing nitrogen and sulfur atoms like 2-amino-6-methyl benzothiazole. The complexes were greenish brown in color. In order to study TGA, first characterized them by elemental analysis, and spectroscopic technique such as IR, NMR and ESR. From the analytical data, the stoichiometry's of the complexes have been observed to be 1:1 (metal:ligand). These complexes have been thermally analyzed using TGA techniques to determine their energy of activation. These complexes show three step thermal degradation corresponding to fatty acid components of the edible oils and each complex has three decomposition steps in the range of 439-738 K. Various equations like Coats-Redfern (CR), Horowitz-Metzger (HM) and Broido equations (BE) were applied to evaluate the energy of activation. The values of energy of activation are observed to be in the following order for both copper groundnut benzothiazole (CGB) and copper sesame benzothiazole (CSeB) complexes: CGB > CSeB. CGB is observed to be more stable than CSeB due to its higher activation energy. The above studies would provide significant information regarding the applications of synthesized agrochemicals and their safe removal through parameters obtained in degradation curves and its relation with energy.

In an effort to improve the yield of Kenyan sesame cultivars the seeds of three cultivars, SPS SIK6, SIK 096 and SPS SIK 50/1 were subjected to 300Gy, 400Gy and 600Gy of gamma rays. A first batch of seeds were subjected to these treatments in March 1994 (Experiment I) while the second batch was treated in March 1995 (Experiment II). The M 1 , M 2 , M 3 and M 4 generations of experiment I and M 1 generation of Experiment II were raised at the University of Nairobi Dryland Research Field Station, Kibwezi from 1994 to 1996. The M 6 and M 7 generations of Experiment I and M 2 of Experiment II were raised at Siaya Farmer's Training Centre in 1997. The effects of radiation in M 1 generation were expressed in reduced and delayed seedling emergence, reduced plant height, sectorial deformed plants, delayed flowering and extremely low yield. There was increased variation in M 2 for most evaluated traits. Plants in M 2 and subsequent generations were scored for a number of yield related morphological traits and days to flowering. Selection was done in the early generations for increased capsule number and earliness. As a result of selection, a total of 88 lines from M 4 generation were used to derive M 5 generation. Further selection in M 6 generation lead to 35 lines being retained for preliminary yield trials in M 7 generations. (author)

By using a semiconductor saturable-absorber mirror (SESAM) optimised for operation in the spectral range from 1100 to 1200 nm, passive mode locking is obtained in a cw bismuth-doped fibre laser. Pumping was performed by a cw ytterbium-doped fibre laser at a wavelength of 1075 nm. The operation of the laser is studied by using either a fibre Bragg grating or a loop fibre Sagnac mirror as the output resonator mirror. Stable laser pulses of duration from 50 ps to 3.5 ns, depending on the output mirror type, were generated. The pulse repetition rate was 11 MHz at a wavelength of ∼1160 nm and the maximum spectral width of 2.1 nm. The maximum average output power was 7.8 mW upon pumping by 1140 mW.

Purpose: This work reports the results of the physics evaluation of a newly released InCise™2 Multileaf Collimator (MLC) installed in our institution. Methods: Beam property data was measured with unshielded diode and EBT2 films. The measurements included MLC leaf transmission, beam profiles, output factors and tissue-phantom ratios. MLC performance was evaluated for one month after commissioning. Weekly Garden Fence tests were performed for leaf / bank positioning in standard (A/P) and clinically relevant non-standard positions, before and after MLC driving exercises of 10+ minutes. Daily Picket Fence test and AQA test, End-to-End tests and dosimetric quality assurance were performed to evaluate the overall system performance. Results: All measurements including beam energy, flatness and symmetry, were within manufacture specifications. Leaf transmission was 0.4% <0.5% specification. The values of output factors ranged from 0.825 (7.6 mm × 7.5 mm) to 1.026 (115.0 mm × 100.1 mm). Average beam penumbra at 10 cm depth ranged from 2.7mm/2.7mm(7.6 mm × 7.5 mm) to 6.0 mm/6.2mm(84.6 mm × 84.7 mm). Slight penumbra difference (<10% from average penumbra for fields >20 mm) was observed in the direction perpendicular to leaf motion due to the tilting of the leaf housing. Mean leaf position offsets was −0.08±0.07mm and −0.13 ± 0.08 for X1 and X2 leaf banks in 13 Garden Fence tests. No significant difference on average leaf positioning offsets was observed between different leaf orientations and before/after MLC driving exercises. Six End-to-End tests showed 0.43±0.23mm overall targeting accuracy. Picket-Fence and AQA showed stable performance of MLC during the test period. Dosimetric point dose measurements for test cases agreed with calculation within 3%. All film measurements on relative dose had Gamma (2%, 2mm) passing rate of >95%. Conclusion: The Incise™2 MLC for CyberKnife M6™ was proven to be accurate and reliable, and it is currently in clinical use

Isolates of Xanthomonas campestris (Pammel) Dawson pv. sesami (Xcs) were collected from various locations in Pakistan and were characterized using several biochemical tests including; (KOH) string test, gram staining, H/sub 2/S production, catalase activity, oxidation/fermentation of glucose, oxidase activity and nitrate reduction. The isolates were positive in tests for KOH string assay, H/sub 2/S, catalase and showed negative reactions in gram staining, oxidase test and nitrate reduction while oxidative utilization of glucose was observed. To develop biological control for the pathogen we isolated numerous bacteria from the rhizosphere of sesame plants and screened them for antagonism against the pathogen using the zone inhibition method. Out of 87 isolates, 9 isolates were inhibitory to the pathogen in vitro. Pseudomonas fluorescens ID-3 exhibited the highest zone of inhibition i.e. 7.97mm. All antagonistic isolates were tested for disease control under greenhouse conditions. Four sesame lines that were found to be moderately resistant in previous studies (i.e. 95001, 96007, 96019, and 20003) were selected for evaluating biocontrol efficacy. The isolates were found to control the disease and reduced severity to 3% compared to untreated plants. The isolate P. fluorescens ID-3 was considered to provide the best disease control with each cultivar. Average biocontrol efficiency (BE) of ID-3 was 78.25% while the best BE was obtained in line 96019, i.e. 81%. (author)

Nitragin, Nitroxin + Bio Phosphate, Nitroxin + Phosphate suloblizing bacteria, Bio Phosphate, Phosphate suloblizing bacteria, Nitroxin treatments increased dry weight of capsules per plant of 62, 53, 51, 36 and 30 percent compared to control, respectively. Although, the effect of PGPR was not significant on sesame seed oil content but Bio Phosphate and Nitragin treatments increased seed oil content by 1 and 1.5 percent, respectively. In general, results showed utilization of PGPR can improve seed yield and seed oil content, which can decrease dependence of sesame seed production to chemical fertilizer, decrease negative environmental impacts and as an ecofriendly inputs can help to produce crops and sustainable agriculture guidlines.

Three iridoids (lamalbid (I1), sesamoside (I2) and shanzhiside methyl ester (I3)) and seven polyphenols (cistanoside F (P1), chlorogenic acid (P2), pedalitin-6-O-laminaribioside (P3), pedaliin (P4), isoacteoside (P6), pedalitin (P7) and martynoside (P8)) were identified in young sesame leaves (Sesamum indicum L.) other than the acteoside (P5) reported previously. P3 was a new compound, and I1, I3, P2 and P8 were found in a species of Sesamum for the first time. HPLC analyses revealed that the compounds I1 (0.29–1.75% of dry leaves), I2 (0.38–0.87%), I3 (0.04–1.07%), P4 (0.01–2.05%) and P5 (0.13–4.86%) were present primarily in young sesame leaves and were found in plants cultivated on different farms (plant height, 30–70 cm). Of the identified compounds, P5 and P6 showed high 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, oxygen radical absorbance capacity (ORAC), and in vitro antiglycation activities. Given its content, P5 makes a major contribution to the biological activities of young sesame leaves. The compounds were examined at six different growth stages of plants cultured in a greenhouse to determine the optimum harvest stage and for end-use assessment. P5 accumulated in the leaves during growth, and the content reached a maximum of 12.9% of dry leaves in the 4th stage (plant height, 74.5±9.7 cm), which is one of the highest percentages reported in plants from nature.

The European Sustainable Nuclear Industry Initiative (ESNII) aims at industrial application of fast reactor technology for a sustainable nuclear energy production. Currently four demonstration projects have a promising outlook in Europe, i.e. the ASTRID project in France, the MYRRHA project in Belgium, the ALFRED pan-European project to be realized in Romania, and SEALER in Sweden. Sodium and lead(-alloys) are envisaged as coolants for these reactors. Obviously, in the development of these reactors, thermal-hydraulics is recognized as a key challenge with emphasis on safety issues. This paper discusses the state-of-the-art knowledge with respect to experiments and simulation techniques as pursued in the Horizon 2020 SESAME (thermal hydraulics Simulations and Experiments for the Safety Assessment of MEtal cooled reactors) project.

Upgrading of sesame from 800 MeV to 2.5 GeV (Summary of the Technical Design)

A Synchrotron-light for Experimental Science and Applications in the Middle East (SESAME), was decided to be built in Jordan as a gift by Germany, based on BESSY 800 MeV synchrotron in Berlin after upgrading to serve as a seed for a new research center in 1998. The initial proposal for SESAME issued in 1999 to move BESSY to the Middle East in a modified form to high performance machine that would cover a broad spectral range, including hard X-rays. For chat BESSY-1, is changed to six-fold symmetry by changing the circumference from 64 to 100 meters and modification of bending magnets, thus the energy was increased to 1 GeV. To reach hard X-ray the intention was to introduce two 13 - pole superconducting wigglers with magnetic field 7.5 tesla, these wigglers provide a critical energy of 5 KeV and useful flux up to 20 KeV. However these wigglers have some disadvantages :1) they are costly, 2) need a special knowledge for running and 3) have an influence on beam behavior. In 2000 - 2001 appeared a scientific need of more beam lines in this spectral range (most users require hard X-ray). The simplest way of doing this is by getting hard X-ray from bending magnets. This is possible by increasing the energy to 2 GeV. Since Jordan will provide the building as a copy of the ANKA (60 m x 60 m) Synchrotron Light Source with 2.5 GeV storage ring. The design of SESAME project has been worked with maximum circumference 124 m. It is a 8- fold symmetry machine with energy 2 GeV. By using gradient bending magnets it is possible to have 12 for the installation of insertion devices and furthermore a reduction of natural emittance down to 18 nm rad. This is really the art of synchrotron light source. This was done in July 2002. To enhance the hard X-ray capability to be more in line, it was suggested to increase the energy up to 2.5 GeV. The option of 2.5 GeV machine is to explore its use with 2 in vacuum undulators, and of running the 2.5 machine at 2 GeV if that is needed for ultra

We have conducted a series of ride-along experiments on the Z facility to ascertain the Hugoniot of silica centered in the stishovite phase over a range 0.4 - 1.0 TPa, together with partial release states produced at the interface between the sample and a fused silica window. The stishovite samples were synthesized in a large-volume multi-anvil press at 15 GPa and 1773 K, with an initial density of 4.29 gm/cc. The new Z experiments on stishovite fill in a gap between gas gun experiments and NIF experiments. The states are compared with the Hugoniots of quartz and fused silica for inferences as to EOS. They are generally consistent with Sesame 7360 predictions. Sound speed constraints from these data are discussed. The new Hugoniot data cross over the melting curve of stishovite; together with the partial-release data and predictions from density-functional theory modeling, they provide insights into the properties of solid and liquid under extreme conditions. These data are fundamentally important for understanding the interior of silicate-based super-Earths.

Full Text Available Solvent extraction as a method of extracting protein from oilseed meals offers the advantage of higher efficiency. Unfortunately, the published literature points to the gap in the work concerned with the necessary equilibrium diagram to design due process equipment for such extracts. Initiated by this lack of basic knowledge, the present study has been undertaken to provide the equilibrium data for three different ternary systems, namely: sesame protein / sodium hydroxide solution system, soybean protein / sodium hydroxide solution system and lupine protein / sodium hydroxide solution system. These oilseed meals were selected because of their high protein content (53.4 %, 46.2 % and 42.3 % protein, respectively. The study also concentrated on the evaluation of the major parameters affecting the extraction process, i.e. the normality of the sodium hydroxide solution used as extracting solvent and the initial oilseed solvent to meal feeding ratio. The results obtained indicate that the best normality of sodium hydroxide solution used for extracting soybean and lupine protein is 0.02N, while 0.04N solution is required for extracting sesame protein. Also, operating at a liquid to solid feed ratio of 30:1 and 50:1 for soybean, sesame and lupine, respectively, is enough to reach a high protein extract. Correlations were presented for each locus of under flow compositions, graphically acquired, and the data are compared with those calculated by analytical solutions.La extracción con disolventes es un método de extracción de proteínas de las harinas de semillas oleaginosas que ofrece la ventaja de su elevada eficacia.

Nishimuta, James F; Levenston, Marc E

Altered synovial levels of various adipokines (factors secreted by fat as well as other tissues) have been associated with osteoarthritis (OA) onset and progression. However, the metabolic effects of adipokines on joint tissues, in particular the fibrocartilaginous menisci, are not well understood. This study investigated effects of several adipokines on release of recently synthesized extracellular matrix in bovine cartilage and meniscus tissue explants. After labeling newly synthesized proteins and sulfated glycosaminoglycans (sGAGs) with 3 H-proline and 35 S-sulfate, respectively; bovine cartilage and meniscus tissue explants were cultured for 6 days in basal medium (control) or media supplemented with adipokines (1 µg/ml of leptin, visfatin, adiponectin, or resistin) or 20 ng/ml interleukin-1 (IL-1). Release of radiolabel and sGAG to the media during culture and the final explant water, DNA, sGAG, and retained radiolabel were measured. Matrix metalloproteinase (MMP-2) and MMP-3 activities were assessed using gelatin and casein zymography, respectively. Water and DNA contents were not significantly altered by any treatment. Visfatin, adiponectin, resistin, and IL-1 stimulated sGAG release from meniscus, whereas only IL-1 stimulated sGAG release from cartilage. Release of 3 H and 35 S was stimulated not only by resistin and IL-1 in meniscus but also by IL-1 in cartilage. Retained 3 H was unaltered by any treatment, while retained 35 S was reduced by visfatin, resistin, and IL-1 in meniscus and by only IL-1 in cartilage. Resistin and IL-1 elevated active MMP-2 and total MMP-3 in meniscus, whereas cartilage MMP-3 activity was elevated by only IL-1. Resistin stimulated rapid and extensive catabolism of meniscus tissue, similar to IL-1, whereas adipokines minimally affected cartilage. Release of newly synthesized matrix was similar to overall release in both tissues. These observations provide further indications that meniscal tissue is more sensitive to pro

2014-01-01

Selection of a starter culture with excellent viability and metabolic activity is important for inoculated fermentation of traditional food. To obtain a suitable starter culture for making Chinese sesame-flavored liquor, the yeast and bacterium community structures were investigated during spontaneous and solid-state fermentations of this type of liquor. Five dominant species in spontaneous fermentation were identified: Saccharomyces cerevisiae, Pichia membranaefaciens, Issatchenkia orientalis, Bacillus licheniformis, and Bacillus amyloliquefaciens. The metabolic activity of each species in mixed and inoculated fermentations of liquor was investigated in 14 different cocultures that used different combinations of these species. The relationships between the microbial species and volatile metabolites were analyzed by partial least-squares (PLS) regression analysis. We found that S. cerevisiae was positively correlated to nonanal, and B. licheniformis was positively associated with 2,3-butanediol, isobutyric acid, guaiacol, and 4-vinyl guaiacol, while I. orientalis was positively correlated to butyric acid, isovaleric acid, hexanoic acid, and 2,3-butanediol. These three species are excellent flavor producers for Chinese liquor. Although P. membranaefaciens and B. amyloliquefaciens were not efficient flavor producers, the addition of them alleviated competition among the other three species and altered their growth rates and flavor production. As a result, the coculture of all five dominant species produced the largest amount of flavor compounds. The result indicates that flavor producers and microbial interaction regulators are important for inoculated fermentation of Chinese sesame-flavored liquor. PMID:24814798

For this purpose a greenhouse experiment was carried out in factorial arrangement based on a completely randomized design with three replications during 2011 year. First factor included: three sesame ecotype (MSC3, MSC6, MSC7 and second factor was 6 fertilizer treatments that included: Incorporation manure and chemical fertilizer (216 g manure and 1 gram chemical fertilizer NPK, Chemical fertilizer (2 g NPK, Vermicompost (192 g, Manure ( 228 g, Compost Sulfur granules (192 g per vase and Control (without any manure or fertilizer. Results indicated that different manure treatments had significant effect on morphological and yield components traits, as the most number and length branch per plant was obtained from incorporation manure and chemical fertilizer treatment. Appling incorporation manure and chemical fertilizer treatment had the most biomass in MSC3 ecotype that in comparison of control treatment was increased almost 73 percent. Consuming incorporation manure and chemical fertilizer treatment in MSC3 ecotype was also obtained the most capsule per plant (21.2, number seed per capsule (54.4, 100-seed weight (0.257 g and seed per plant with (1.95 g. The least seed weight per plant with 0.450 g was observed in MSC7 ecotype from application of control treatment. Response of three sesame ecotype (MSC3, MSC6, MSC7 to applied vermin-compost manure was similar; as the amount of seed weight per plant was increased more than 1 g per plant in all these ecotypes and in others fertilizer treatments was not observed this trend. There was significant positive correlation between seed weight per plant and number of capsule per plant (r=0.83**, height (r=0.68** and biomass (r=0.51**. The results showed that incorporation manure and chemical fertilizer was improved on growth and yield characteristics of sesame plant.

Objective of this research was to evaluate adsorption of heavy metals in mono and multimetal forms onto sesame straw biochar (SSB). Competitive sorption of metals by SSB has never been reported previously. The maximum adsorption capacities (mgg(-1)) of metals by SSB were in the order of Pb (102)≫Cd (86)≫Cr (65)>Cu (55)≫Zn (34) in the monometal adsorption isotherm and Pb (88)≫Cu (40)≫Cr (21)>Zn (7)⩾Cd (5) in the multimetal adsorption isotherm. Based on data obtained from the distribution coefficients, Freundlich and Langmuir adsorption models, and three-dimensional simulation, multimetal adsorption behaviors differed from monometal adsorption due to competition. Especially, during multimetal adsorption, Cd was easily exchanged and substituted by other metals. Further competitive adsorption studies are necessary in order to accurately estimate the heavy metal adsorption capacity of biochar in natural environments. Copyright © 2015 Elsevier Ltd.

Induced mutants for the improvement of sesame and hybrid seed production

International Nuclear Information System (INIS)

Murty, G.S.S.

2001-01-01

With an overall objective to develop hybrids in sesame, induced mutants were used in cross breeding and five initial yield trials were conducted. For obtaining the mutant hybrids, recessive morphological mutants were used as female, and check varieties as male parents. In each trial, seed yields of mutant hybrids were compared with: i) the original parent in which the mutants were induced, ii) best check variety and iii) best cultivar hybrid. Among 138 mutant hybrids evaluated between 1994 and 1997, 18 showed superiority. In the development of hybrids, it is also desirable to have male sterile lines. By irradiating seeds with 400 Gy gamma rays, four genetic male sterile mutants were isolated. One of them, TMST-11 appears to be promising for breeding programme showing 100% male sterility and characterised by dark green foliage. To study the percent outcrossing, a monogenic chlorina mutant which can be identified from the seedling stage, was used in experiments conducted for two years. Among open pollinated plants, 92-98% plants were found outcrossed. Based on plant to row progenies, percent outcrossing ranged between 0.0 to 13.8%. (author)

The NASA/GEWEX Surface Radiation Budget (SRB) project produces shortwave and longwave surface and top of atmosphere radiative fluxes for the 1983-near present time period. Spatial resolution is 1 degree. The new Release 4 uses the newly processed ISCCP HXS product as its primary input for cloud and radiance data. The ninefold increase in pixel number compared to the previous ISCCP DX allows finer gradations in cloud fraction in each grid box. It will also allow higher spatial resolutions (0.5 degree) in future releases. In addition to the input data improvements, several important algorithm improvements have been made since Release 3. These include recalculated atmospheric transmissivities and reflectivities yielding a less transmissive atmosphere. The calculations also include variable aerosol composition, allowing for the use of a detailed aerosol history from the Max Planck Institut Aerosol Climatology (MAC). Ocean albedo and snow/ice albedo are also improved from Release 3. Total solar irradiance is now variable, averaging 1361 Wm-2. Water vapor is taken from ISCCP's nnHIRS product. Results from GSW Release 4 are presented and analyzed. Early comparison to surface measurements show improved agreement.

The layout and the optical performance of the SGM branch of the D09 bending-magnet beamline, under construction at SESAME, are presented. The beamline is based on the Dragon-type design and delivers photons over the spectral range 15-250 eV. One fixed entrance slit and a movable exit slit are used. The performance of the beamline has been characterized by calculating the mirror reflectivities and the grating efficiencies. The flux and resolution were calculated by ray-tracing using SHADOW. The grating diffraction efficiencies were calculated using the GRADIF code. The results and the overall shapes of the predicted curves are in reasonable agreement with those obtained using an analytical formula.

Full Text Available Introduction Plant association with mycorrhiza has been considered as one of the options to improve input efficiency particularly for water and nutrient - (Allen and Musik, 1993; Bolan, 1991. This has been due to kncreasing the absorbing area of the root and therefore better contact with water and nutrients. Inoculation with mycorrhiza enhances nutrient uptake with low immobility such as phosphorus and solphur-, improve association and could be an option to drought and other environmental abnormalities such as salinity (Rice et al., 2002. Moreover, higher water use efficiency (WUE for crops -has been reported in the literatures (Sekhara and Reddy, 1993.The sustainable use of scarce water resources in Iran is a priority for agricultural development. The pressure of using water in agriculture sector is increasing, so creating ways to improve water-use efficiency and taking a full advantage of available water are crucial. Water stress reduce crop yield by impairing the growth of crop canopy and biomass. Scheduling water application is very crucial for efficient use of drip irrigation system, as excessive irrigation reduces yield, while inadequate irrigation causes water stress and reduces production. The aim of present study was to evaluate the symbiotic effect of mycorrhiza on yield, yield components and water use efficiency of sesame under different irrigation regimes in Mashhad. Material and Methods In order to investigate the impact of inoculation with two species of Arbuscular mycorrhiza fungi on yield, yield components and water use efficiency (WUE of sesame (Sesamum indicum L. under different irrigation regimes, an experiment was conducted as split plot based on a randomized complete block design with three replications during two growing seasons 2009-2010 and 2010-2011 at the Agricultural Research Station, College of Agriculture, Ferdowsi University of Mashhad..

The disposition of newly synthesized ACh subsequent to depletion of vesicular endogenous ACh by stimulation was studied in the electromotor nerve terminals of Torpedo marmorata using (/sup 3/H) acetate as a precursor of ACh. Little vesicular (/sup 3/H) ACh could be isolated from tissue immediately after stimulation at 1 Hz. After 3 h post-stimulation recovery the newly-synthesized (/sup 3/H) ACh is found predominantly in a subpopulation of vesicles distinct from the vesicles containing most of the endogenous poorly labelled ACh. Restimulation of the tissue causes release of highly labelled ACh with a specific radioactivity (SRA) comparable to that of the newly synthesized (/sup 3/H) ACh in the highly labelled subpopulation of vesicles and significantly greater than the SRA of ACh in the main vesicular pool of the total tissue.

Exenatide extended release (ER) is a glucagon-like peptide-1 analogue that increases insulin secretion, inhibits glucagon secretion and induces satiation in humans with type 2 diabetes mellitus. The use of exenatide ER is safe and stimulates insulin secretion in healthy cats. The objective of this study is to assess the safety of exenatide ER and its effect on body weight, remission and metabolic control in newly diagnosed diabetic cats receiving insulin and a low-carbohydrate diet. Thirty client-owned cats. Prospective placebo-controlled clinical trial. Cats were treated with exenatide ER or 0.9% saline, administered SC, once weekly. Both groups received insulin glargine and a low-carbohydrate diet. Exenatide ER was administered for 16 weeks, or in cats that achieved remission it was given for 4 weeks after discontinuing insulin treatment. Nonparametric tests were used for statistical analysis. Cats in the exenatide ER and placebo groups had transient adverse signs including decreased appetite (60% vs. 20%, respectively, P = .06) and vomiting (53% vs. 40%, respectively, P = .715). Body weight increased significantly in the placebo group (P = .002), but not in cats receiving exenatide ER. Cats on exenatide ER achieved remission or good metabolic control in 40% or 89%, respectively, whereas in control cats percentages were 20% or 58% (P = .427 and P = .178, respectively). Exenatide ER is safe in diabetic cats and does not result in weight gain. Our pilot study suggests that, should there be an additional clinically relevant beneficial effect of exenatide ER in insulin-treated cats on rate of remission and good metabolic control, it would likely approximate 20% and 30%, respectively.

New experimental designs for the extraction of polyphenols from different seeds including Basil seed, Red seed, Sesame seeds and Ajwan seeds were investigated. Four variables the concentration and volume of methanol and NaOH solutions as well as the temperature and time of extraction were varied to see their effect on total phenol extraction. The temperature was varied in the range from 25°C to 200°C while the time in the range from 30 to 200minutes. Response surface methodology was used to optimize the extraction parameters. The estimation of polyphenols was measured through phenols reduction UV-Vis spectroscopic method of phosphotungstic-phosphomolybdic acids (Folin-Ciocalteu's reagent). Calibration curve was made by using tannic acid as a polyphenols standard in the concentration range from 0.1 to 10ppm. The regression line obtained shows the value of correlation coefficient i.e. R=0.930 and Root mean square error of cross validation (RMSEC) value of 0.0654. The Basil seeds were found containing the highest amount of total phenols i.e. 785.76mg/100g. While the Sesame seeds having the least amount i.e. 33.08mg/100g. The Ajwan seeds and the Red seeds are containing the medium amounts i.e. 379mg/100g and 220.54mg/100g respectively. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Pramipexole, the most commonly prescribed dopamine agonist worldwide, meanwhile serves as a reference substance for evaluation of new drugs. Based on numerous clinical data and vast experiences, efficacy and safety profiles of this non-ergoline dopamine agonist are well characterized. Since October 2009, an extended-release formulation of pramipexole has been available for symptomatic treatment of Parkinson's disease. Pramipexole administration can be cut down from three times to once a day due to the newly developed extended-release formulation. This is considerable progress in regard to minimizing pill burden and enhancing compliance. Moreover, the 24 h continuous drug release of the once-daily extended-release formulation results in fewer fluctuations in plasma concentrations over time compared to immediate-release pramipexole, given three times daily. The present study summarizes pharmacokinetics and all essential pharmacological and clinical characteristics of the extended-release formulation. In addition, it provides all study data, available so far, with regard to transition and de-novo administration of extended-release formulation for patients with Parkinson's disease. It further compares efficacy and safety data of immediate-release pramipexole with the extended-release formulation of pramipexole.

2016-02-01

Full Text Available Introduction: Phosphorus (P is considered to be one of the most essential macro elements required for growth and development of plants, but, due to low solubility and fixation in soils, only a small fraction of phosphorus in soil (1 ppm or 0.1% is readily available to plants. chemical fertilizers are widely used in meeting the phosphorous need of crops. However, as the fertilizer production is dependent upon fossil energy sources, continuous use of chemical fertilizers has become a matter of great concern, not only because of the diminishing availability of costly inputs but environmental concerns also. Under this background, it has obviously brought the subject of mineral phosphate solubilization in the forefront. A group of soil microorganisms is recognized to be involved in microbial phosphate solubilization mechanisms through which insoluble forms of inorganic and organic phosphates convert into soluble forms (HPO4-2 or H2PO4-. Acidification of the medium, chelating, exchange reactions and production of various acids has been discussed as the key processes attributed to the conversion. Phosphate solubilizing bacteria (PSB are a group of plant growth promoting rhizobacteria (PGPR that convert unavailable forms of phosphorus to available forms and it helps to the growth and yield of plant. The use of plant growth promoting rhizobacteria (PGPR is considered one of the most important factors increasing sesame yields. Therefore, the aim of the present study was to investigate the interactive effects of PGPR and phosphorus fertilizer on some growth parameters and components of yield and also phosphorus and Zinc uptake in sesame. Materials and Methods: In order to investigation of the effect of combined application of phosphate solubilizing bacteria and phosphorus fertilizer on growth and yield of Sesame, a greenhouse experiment was conducted as factorial based on completely randomized design with three replications including five levels of

Full Text Available The objective of this study was to evaluate the aerosol-release time in the development of a new automatic adapter for metered dose inhaler. With this device, regular manually operated metered dose inhalers become automatic. During the study, an inhalation simulator was designed and tested with the newly developed mechatronic system. By adjusting the volume and the pressure of the vacuum tank, most human inhalation waveforms were able to simulate. As an example, regular quick-deep and slow-deep waveforms were matched within reasonable accuracy. Finally, with the help of dynamic image processing, the aerosol-release time (Tr was carefully measured and fully discussed, including the switch-on time (Ts, the mechatronics-hysteresis (Tm and the intentional-delay (Ti. Under slow-deep inhalation condition which is suitable for metered dose inhaler medicine delivery, the switch-on flow-rate could reach as low as 10 L/min, and the corresponding switch-on time was approximately 0.20 s. While the mechatronics-hysteresis depended on the brand of metered dose inhaler, assuming there was no intentional-delay, the aerosol-release time could be as low as 0.40 and 0.60 s, respectively, for two commercially available metered dose inhalers studied in this article. Therefore, this newly developed mechatronic adapter system could ensure aerosol-release time (Tr within satisfactory range for metered dose inhalers.

This document is very similar to KSCI-19092-003, Planet Reliability Metrics: Astrophysical Positional Probabilities, which describes the previous release of the astrophysical positional probabilities for Data Release 24. The important changes for Data Release 25 are:1. The computation of the astrophysical positional probabilities uses the Data Release 25 processed pixel data for all Kepler Objects of Interest.2. Computed probabilities now have associated uncertainties, whose computation is described in x4.1.3.3. The scene modeling described in x4.1.2 uses background stars detected via ground-based high-resolution imaging, described in x5.1, that are not in the Kepler Input Catalog or UKIRT catalog. These newly detected stars are presented in Appendix B. Otherwise the text describing the algorithms and examples is largely unchanged from KSCI-19092-003.

In the approximately 70 year-old history of induced mutations, there are many examples on the development of new and valuable alteration in plant characters significantly contributing to increased yield potential of specific crops. However, knowledge on the success of induced mutations in crop improvement among geneticists and breeders is usually limited to species of their interest. The present paper contains a comprehensive list of officially released mutant varieties, based on information from plant breeders. The number of mutant varieties officially released and recorded in the FAO/IAEA Mutant Varieties Database before the end of 2000 is 2,252. Almost half of these varieties have been released during the last 15 years. Considering a significant delay in the dissemination of information on newly released varieties and difficulties in the collection of such data, there has been a renaissance in the use of mutation techniques in crop improvement. At the demand of geneticists, plant breeders, and more recently molecular geneticists, for information on released mutant varieties of specific crops, the MVD was transferred to the web site of the FAO/IAEA Joint Division. The MVD will be available on our web pages early in 2001. (author)

2003-01-01

The release of Streptomyces albus propagules from contaminated agar an ceiling tile surfaces was studied under controlled environmental condition in a newly developed aerosolization chamber. The experiments revealed tha both spores and cell fragments can be simultaneously released from the colonized surface by relatively gentle air currents of 0.3 m s -1 . A 100x increase of the air velocity can result in a 50-fold increase in the number of released propagules. The aerosolization rate depends strongly on the typ and roughness of the contaminated surface. Up to 90% of available actinomycete propagules can become airborne during the first 10 min of th release process. Application of vibration to the surface did not reveal an influence on the aerosolization process of S. albus propagules under th tested conditions. This study has shown that propagules in the fine particle size range can be released in large amounts from contaminated surfaces Measurement of the number of S. albus fragments in the vicinity of contaminated area, as an alternative to conventional air or surface sampling appears to be a promising approach for quantitative exposure assessment

Full Text Available Introduction Sesame (Sesamum indicum L. belongs to pedaliaceae family and is one of the most important oilseed crops that will grow in relatively dry region. Each leaf node will have one capsule but in some sesame ecotypes the number of capsule per leaf node can increase (Langham and Wiemers, 2002. Factors such as agricultural operations, growing substrates and variety affect yield and harvest index. Iron is one of the main micronutrient that can affect growth and development (Miller et al., 1982. This research was conducted to study the effects of leaf nutrition on the number of capsules per leaf node of sesame. Materials and Methods In order to study the effects of leaf nutrition on the number of capsules per leaf node in sesame plant (sesamum indicum L., an experimental was conducted at Khorasan Razavi Agricultural Education Center, Iran, 1n 2014. This study was done as a factorial arrangement with two factors, kind of seed and the concentrations of ferrous sulphate on the basis completely randomized block design with three replications. The first factor was two seed types (one type has been taken from leaf node with three capsules and the other seeds were taken from leaf node with one capsule in sesame plant. The second factor was three concentration of ferrous sulphate (0, 50 and 100 ppm that applied in %50 vegetation, flowering and capsule phase. Morphological and yield components traits were measured. Data were analyzed with MSTAT-C software and means comparison were done with Duncan multiple range test in 5 percent probability. Results and Discussion The first factor (type of seed showed significant difference on height, length of branch, fresh and dry shoot weight, dry weight of capsule, number capsules per plant, 1000 seed weight and seed weight per plant. Plants growing from the seeds with three capsules in leaf node (Cap2 had the maximum height with 88.2 cm that was 20% more than plants that growth from seeds with one capsule in leaf

Seeds of four sesame cultivars, Muganli-57, Oezberk-82, Camdibi and Goelmarmara were irradiated in the range of 150-750 Gy doses of gamma rays in three different experiments. Irradiated seeds with their controls were sown in 1994, 1995 and 1997 to grow M 1 . Three different harvesting procedures were applied to the M 1 populations, i.e., plant harvesting, branch harvesting and bulk harvesting. M 2 generations, therefore, were both grown as progeny rows and bulk populations. Potential mutants fitting the breeding objectives were selected after careful screening during the growing period; there were mutations for closed capsule, determinate growth habit, wilting tolerance, chlorophyll deficiency, hairy capsule and multicarpelate, sterility as well as in quantitative traits such as flowering time, capsule size, plant height. In M 3 , the selected mutants with their normal looking sibs from the same progeny were grown again to confirm mutant traits in progeny rows of 2 meters length and 40 cm apart. After emergence, the plants within a row were thinned to 5 cm apart. Normal agronomic practices were applied to the nurseries. It was finally concluded that recovering unique induced mutants, such as closed capsules, is not a matter of ''luck'' but the result of growing large M 2 populations, preferably in plant progeny rows, and careful screening.

Full Text Available An experiment was conducted to evaluate the effect of using graded levels of roasted sesame hulls (RSH on growth performance and meat quality characteristics in broiler chickens. A total of 360 day-old Lohmann chicks were randomly allocated into 24 floor pens and raised over 42 days. One of four dietary treatments was assigned to each group of six pens in a completely randomized fashion. The chicks in the control group were fed a corn-soybean based diet (RSH-0, while the chicks in treatments two, three, and four were fed graded levels of RSH at 4% (RSH-4, 8% (RSH-8, and 12% (RSH-12, respectively. Diets were formulated to meet broiler chicks’ requirements according to the National Research Council for both starter and finisher rations. The results showed that RSH inclusion increased (P<0.05 feed intake and final body weight without adversely affecting the feed conversion ratio. Broiler chicks fed RSH-12 had heavier (P<0.05 breast and leg cuts compared to the control-fed group with no change to their chemical composition. Water holding capacity (WHC, cooking loss (CL, and shear force (SF reported similar results in all dietary groups. The chemical composition of both thigh and breast cuts was not affected by the RSH. After one day of thawing, colour coordinates of breast cuts behaved similarly in all dietary groups. The results of this study suggest that the addition of RSH to broiler diets up to 12% improves their growth performance; nevertheless, carcass characteristics and meat quality showed no alterations compared to the control-fed group.

Controlled-release fertilizer offers a number of advantages in relation to crop production in newly reclaimed soils. Butadiene styrene latex emulsion is one of the promising polymer for different purposes. In this work, laboratory evaluation of butadiene styrene latex emulsion 24/76 polymer loaded with a mixed fertilizer was carried out. Macro nutrients (N, P and K) and micro-nutrients(Zn, Fe, and Cu) were extracted by basic extract from the polymer fertilizer mixtures. Micro-sampling technique was investigated and applied to measure Zn, Fe, and Cu using flame atomic absorption spectrometry in order to overcome the nebulization difficulties due to high salt content samples. The cumulative releases of macro and micro-nutrients have been assessed. From the obtained results, it is clear that the release depends on both nutrients and polymer concentration in the mixture. Macro-nutrients are released more efficient than micro-nutrients of total added. Therefore it can be used for minimizing micro-nutrients hazard in soils

An accident occurred at the Fukushima Dai-ichi Nuclear Power Plant in March 2011 at which time large amounts of radionuclides were released into the atmosphere and the sea. In early May 2011, it was found that newly emerged tea (Camellia sinensis) leaves contained radiocesium, both 134 Cs and 137 Cs in some areas more than 300 km away from the Fukushima plant. To understand the mechanisms of radiocesium transfer to newly emerged tissues (shoots, leaves and fruits) of other plants in the future, radiocesium concentrations in newly emerged leaves of 14 plant species collected from the sampling areas in and near National Institute of Radiological Sciences in Chiba, Japan. The studied plant types were: (1) herbaceous plants, (2) woody plants with no old leaves at the time of the March accident, and (3) woody plants with old leaves out before the accident. About 40–50 d after the start of the accident, newly emerged leaves from woody plant with old leaves tended to show higher values than other woody or herbaceous plants. Concentrations of radiocesium in newly emerged tissues of trees decreased with time, but they did not decrease to the level of herbaceous plants. The type of the plant and presence of old leaves at the time of the heavy deposition period affected the radiocesium concentrations in newly emerged tissues.

Full Text Available A newly dead cadaver simulation is practiced on the physical remains of the dead before the onset of rigor mortis. This technique has potential benefits for providing real-life in-situ experience for novice providers in health care practices. Evolving ethical views in health care brings into question some of the ethical aspects associated with newly dead cadaver simulation in terms of justification for practice, autonomy, consent, and the need of disclosure. A clear statement of policies and procedures on newly dead cadaver simulation has yet to be implemented. Although there are benefits and disadvantages to an in-situ cadaver simulation, such practices should not be carried out in secrecy as there is no compelling evidence that suggests such training as imperative. Secrecy in these practices is a violation of honor code of nursing ethics. As health care providers, practitioners are obliged to be ethically honest and trustworthy to their patients. The author explores the ethical aspects of using newly dead cadaver simulation in training novice nursing providers to gain competency in various lifesaving skills, which otherwise cannot be practiced on a living individual. The author explores multiple views on cadaver simulation in relation to ethical theories and practices such as consent and disclosure to family.
Low-timing-jitter, stretched-pulse passively mode-locked fiber laser with tunable repetition rate and high operation stability

We design a low-timing-jitter, repetition-rate-tunable, stretched-pulse passively mode-locked fiber laser by using a nonlinear amplifying loop mirror (NALM), a semiconductor saturable absorber mirror (SESAM), and a tunable optical delay line in the laser configuration. Low-timing-jitter optical pulses are stably produced when a SESAM and a 0.16 m dispersion compensation fiber are employed in the laser cavity. By inserting a tunable optical delay line between NALM and SESAM, the variable repetition-rate operation of a self-starting, passively mode-locked fiber laser is successfully demonstrated over a range from 49.65 to 50.47 MHz. The experimental results show that the newly designed fiber laser can maintain the mode locking at the pumping power of 160 mW to stably generate periodic optical pulses with width less than 170 fs and timing jitter lower than 75 fs in the 1.55 µm wavelength region, when the fundamental repetition rate of the laser is continuously tuned between 49.65 and 50.47 MHz. Moreover, this fiber laser has a feature of turn-key operation with high repeatability of its fundamental repetition rate in practice

Full Text Available Introduction Salinity stress is regarded as one of the most important abiotic factors limiting plant growth and agricultural products, particularly in arid and semi-arid regions. Sesame (Sesamum indicum L. is an important oilseed crop rated moderately salt tolerant and capable of producing profitable crops in saline conditions. Germination and seedling establishment are critical stages in the life cycle of plants especially under stress conditions. Different methodologies have been adopted by plant physiologists in different crops to alleviate salt stress. Seed priming has proven beneficial in this regard in many important agricultural crops. Salicylic acid is one of the physiological processes regulators that it increases resistant of plants to environmental stresses such as salinity stress. Materials and Methods To evaluate the effect of different levels of salinity and seed pretreatment with salicylic acid (SA, on some growth indices and nutrient uptake of sesame (Sesamum indicum L. seedling, a factorial experiment with completely randomized design and four replicates was conducted in Department of Agronomy, Rafsanjan University of Vali-e- Asr. Factors were seed pretreatment with three levels including, distilled water, 1 mM salicylic acid and 2.5 Mm salicylic acid and salinity at three levels: control (Hoagland standard solution, 2.5 dS.m-1, 6 and 9 dS.m-1. A dry seed treatment (no pretreatment was also added and considered as control. Results and Discussion Results showed that at 9 dS/m-1both SA concentrations caused significant increase in emergence percentage compared to dry seed and distilled water. Plant leaf area and SPAD values decreased along with salinity in dry seed and distilled water, nevertheless, at 2.5 mM SA, values were not significantly different between 6 and 9 dS.m-1. On the other hand, SA seed pretreatment decreased shoot Na and increased K content, although shoot Mg and P contents were the highest at 1 and 2.5 mM SA

Full Text Available This paper applies Response Surface Design (RSD to model the experimental data obtained from the extraction of sesame seeds oil using n-hexane, chloroform and acetone as solvents under different operating conditions. The results obtained revealed that n-hexane outperformed the extraction obtained using chloroform and acetone. The developed model predicted that n-hexane with a rotational speed of 547 rpm and a contact time between the solvent and seeds of 19.46 hours with solvent: seeds ratio of 4.93, yields the optimum oil extracted of 37.03 %, outperforming chloroform and acetone models that gave prediction for 4.75 and 4.21 respectively. While the maximum predictions yield for chloroform is 6.73 %, under the operating conditions of 602 rpm, and 24 hours contact time, with a ratio of solvent: seeds of 1.74. On the other hand the acetone maximum prediction is only 4.37 %, with operational conditions of 467 rpm, and 6.00 hours contact time, with a ratio of solvent: seeds of 1. It is has been found that the maximum oil extraction yield obtained from the chloroform (6.73 % and Acetone (4.37 % is much lower than that predicted by n-hexane 37.03 %.

Ganesan, J.

2001-01-01

In Tamil Nadu, sesame growing on available residual soil moisture after the rice harvest is expanding. In order to achieve higher and more reliable yields under these conditions, a more suitable plant type is needed: with shorter stature and growing period, moderate basal branching and higher productivity. Seeds of 6 varieties were treated with gamma rays, diethyl sulphate (DES) and ethyl methane sulphonate (EMS). The M 1 -M 4 generations were studied and several promising mutants were selected. Among them were also male sterile mutants; it is thought that such mutants will assist in producing hybrid varieties which will give the desired yield breakthrough. (author)

Simultaneous initiation of degranulation and inhibition of leukotriene release by soman in human basophils

Energy Technology Data Exchange (ETDEWEB)

Meier, H.L.; Warner, J.; MacGlashan, D.W.

1995-12-31

Previous studies noted that the serine esterase inhibitor, soman, could induce histamine release from human basophils. To investigate the mechanisms by which soman causes histamine release (a preformed mediator), we also examined its ability to induce leukotriene release (a newly synthesized mediator) from basophils. We found that no leukotriene release followed activation with soman, while histamine release was usually greater than 70%. In addition, soman and diisopropyl-fluorophosphate were found actively to suppress low level spontaneous leukotriene release as well as ongoing leukotriene release induced by anti-IgE antibody. Soman (0.3 mM) was able to stop leukotriene release as rapidly as the calcium chelator, EDTA. In a series of control experiments, it was noted that soman did not influence the metabolism of LTC4 to LTD4 or LTE4 (for which little metabolism occurred), eliminating the possibility that reduced LTC4 release could have resulted from its enhanced metabolism. Therefore, using one compound (soman), basophils could be simultaneously activated to degranulate while having the pathway leading to leukotriene release actively suppressed. These results provide further evidence that histamine and leukotriene release are independent pathways resulting from the activation of basophils.

2016-09-01

Full Text Available In this study, the adsorption of active carbon derived from waste sesame seeds coated with polyvinyl alcohol (AC/PVA was investigated for removing red 198 and blue 19 reactive dyes from textile effluents. The batch process was carried out to identify such parameters as pH, adsorbent dose, contact time, and initial dye concentration involved in the dye removal adsorption capacity of AC/PVA. Also, batch kinetic and isotherm experiments were conducted. Results indicated that the maximum dye removal was obtained in an acidic pH over 90 min of contact time and that adsorption rates followed the pseudo-second-order kinetics. Blue and red dye concentrations were determined using the spectrophotometric method at 590 and 517 nm, respectively. It may be concluded that AC/PVA is capable of removing blue and red reactive dyes and can be used as an efficient, cheap, and accessible adsorbent for treating textile effluents.

2013-01-01

We have developed a newly designed non-explosive release actuator that can replace currently used release devices. The release mechanism is based on a separation mechanism, which relies on segmented nuts and a shape memory alloy (SMA) wire trigger. A quite fast and simple trigger operation is made possible through the use of SMA wire. This actuator is designed to allow a high preload with low levels of shock for the solar arrays of medium-size satellites. After actuation, the proposed device can be easily and instantly reset. Neither replacement, nor refurbishment of any components is necessary. According to the results of a performance test, the release time, preload capacity, and maximum shock level are 50 ms, 15 kN, and 350 G, respectively. In order to increase the reliability of the actuator, more than ten sets of performance tests are conducted. In addition, the proposed release actuator is tested under thermal vacuum and extreme vibration environments. No degradation or damage was observed during the two environment tests, and the release actuator was able to operate successfully. Considering the test results as a whole, we conclude that the proposed non-explosive release actuator can be applied reliably to intermediate-size satellites to replace existing release systems.

Whitefly, Bemisia tabaci (Genn.) is a polyphagous pest and is reported on more than 600 host plants worldwide. Different methods are being used for its control. The present experiment was conducted to determine the effect of some plant extracts of mint (Mentha spp.) and gera-nium (Pelargonium graveolens) and soybean oil (Glycine max), mustard oil (Brassica spp.) and taramera oil (Eruca sativa) against whitefly, Bemisia tabaci on sesame crop. The data were recorded 24h before and 24h, 48h, 72h and 168h after application of each spray material. The results showed that whitefly population was significantly suppressed by both the botanical oils and extracts as compared to the control treatment but in general botanical oils showed significant results as compared to plant extracts. Soybean oil was quite effective in reducing whitefly population per leaf, while after second spray soybean oil and extract of Mentha spp. was more effective in the reducing whitefly population per leaf. The results indicated that plant derived oils and extracts have the potential to be used in plant protection strategies but still more research has to be incorporated in the pest management programmes.

Recent efforts to restore remnant or extirpated populations of freshwater mussels have focused on artificial propagation as an effective and practical conservation strategy. Although artificially cultured juveniles have been produced and released to the wild at various times of the year, no study has investigated the best time of year to release these juveniles. Newly metamorphosed juveniles of the wavyrayed lampmussel (Lampsilis fasciola) were released into a stream-fed fish hatchery raceway during March, June, and September. Growth and survival rates were measured 32, 52, 72, and 92 days post-metamorphosis. Juveniles released in June experienced the greatest growth and survival rates. Juveniles released in September and March experienced high mortality within the first month of release and exhibited poor growth in the cool water conditions typical of those seasons. Overwinter survival exhibited a size-dependent relationship.

Full Text Available Leather tanning industries release effluents into the river through various canals. These effluents contain chromium (VI contaminating the river and the ground water as well. To fix a solution for this issue a simple and selective solvent extraction method has been applied by using a newly synthesized quaternary ammonium salt viz 2-benzoylethylheptyldimethylammonium bromide. By varying the parameters such as quaternary ammonium salts, sulfuric acid, pH, solvents, equilibration time and aqueous organic ratio the extraction efficiency has been determined.

Children's media have the capacity to prepare young learners to develop the knowledge, attitudes, and skills they need to contribute to a more peaceful world. Research suggests international coproductions of Sesame Street and other children's media efforts are linked to positive impact on how viewers perceive themselves and their own cultures, as well as how they perceive others. Creating such media, however, relies on a commitment to a complex development process where the educational needs of children are considered alongside intra- and intergroup dynamics and political realities. This paper presents a practitioners' perspective on the essential components of children's media programs for peacebuilding and, in so doing, recommends a way forward for producing children's media in this domain. © 2018 Wiley Periodicals, Inc.

Furnish, Michael; Shulenburger, Luke; Desjarlais, Michael; Fei, Yingwei

2017-06-01

We have conducted a series of ride-along experiments on the Z facility to ascertain the Hugoniot of silica centered in the stishovite phase over a range 0.4 - 1.0 TPa, together with partial release states produced at the interface between the sample and a fused silica window. The stishovite samples were synthesized in a large-volume multi-anvil press at 15 GPa and 1773 K, with an initial density of 4.29 gm/cc. The new Z experiments on stishovite fill in a gap between gas gun experiments and NIF experiments. The states are compared with the Hugoniots of quartz and fused silica for inferences as to EOS. They are generally consistent with Sesame 7360 predictions. Sound speed constraints from these data are discussed. The new Hugoniot data cross over the melting curve of stishovite, providing insight into the properties of solid and liquid under extreme conditions in conjunction with predictions from density-functional theory modeling. These data are fundamentally important for understanding the interior of silicate-based super-Earths.

Direct comparisons between radiolabelled and endogenous dopamine (DA) release from superfused rat brain slices have been made. Striatal slices were prelabelled with [ 3 H]dopamine ([ 3 H]DA), then superfused at 0.5 ml/min and the released catecholamines analyzed by HPLC with electrochemical detection and radioactivity present in superfusate fractions also counted. The studies indicate that labelled and endogenous amine release do not always occur in parallel, and that major causes of discrepancy between them may include the presence of a large newly-synthesized component in endogenous release and the uneven distribution of labelled amine within endogenous releasable pools. The results also suggest that the prelabelling process itself may alter the pools contributing to subsequent endogenous release. (Auth.)
Retention and release of tritium in aluminum clad, Al-Li alloys

International Nuclear Information System (INIS)

Louthan, M.R. Jr.

1991-01-01

Tritium retention in and release from aluminum clad, aluminum-lithium alloys is modeled from experimental and operational data developed during the thirty plus years of tritium production at the Savannah River Site. The model assumes that tritium atoms, formed by the 6 Li(n,α) 3 He reaction, are produced in solid solution in the Al-Li alloy. Because of the low solubility of hydrogen isotopes in aluminum alloys, the irradiated Al-Li rapidly becomes supersaturated in tritium. Newly produced tritium atoms are trapped by lithium atoms to form a lithium tritide. The effective tritium pressure required for trap or tritide stability is the equilibrium decomposition pressure of tritium over a lithium tritide-aluminum mixture. The temperature dependence of tritium release is determined by the permeability of the cladding to tritium and the local equilibrium at the trap sites. This model is used to calculate tritium release from aluminum clad, aluminum-lithium alloys. 9 refs., 3 figs

Electronic questionnaires can ease data collection in randomized controlled trials (RCTs) in clinical practice. We found no existing software that could automate the sending of emails to participants enrolled into an RCT at different study participant inclusion time points. Our aim was to develop suitable software to facilitate data collection in an ongoing multicenter RCT of low back pain (the Acuback study). For the Acuback study, we determined that we would need to send a total of 5130 emails to 270 patients recruited at different centers and at 19 different time points. The first version of the software was tested in a pilot study in November 2013 but was unable to deliver multiuser or Web-based access. We resolved these shortcomings in the next version, which we tested on the Web in February 2014. Our new version was able to schedule and send the required emails in the full-scale Acuback trial that started in March 2014. The system architecture evolved through an iterative, inductive process between the project study leader and the software programmer. The program was tested and updated when errors occurred. To evaluate the development of the software, we used a logbook, a research assistant dialogue, and Acuback trial participant queries. We have developed a Web-based app, Survey Email Scheduling and Monitoring in eRCTs (SESAMe), that monitors responses in electronic surveys and sends reminders by emails or text messages (short message service, SMS) to participants. The overall response rate for the 19 surveys in the Acuback study increased from 76.4% (655/857) before we introduced reminders to 93.11% (1149/1234) after the new function (P<.001). Further development will aim at securing encryption and data storage. The SESAMe software facilitates consecutive patient data collection in RCTs and can be used to increase response rates and quality of research, both in general practice and in other clinical trial settings. ©Trygve Skonnord, Finn Steen, Holgeir

Estimating the dose distribution in a victim's body is a relevant indicator in assessing biological damage from exposure in the event of a radiological accident caused by an external source. When the dose distribution is evaluated with a numerical anthropomorphic model, the posture and morphology of the victim have to be reproduced as realistically as possible. Several years ago, IRSN developed a specific software application, called the simulation of external source accident with medical images (SESAME), for the dosimetric reconstruction of radiological accidents by numerical simulation. This tool combines voxel geometry and the MCNP(X) Monte Carlo computer code for radiation-material interaction. This note presents a new functionality in this software that enables the modelling of a victim's posture and morphology based on non-uniform rational B-spline (NURBS) surfaces. The procedure for constructing the modified voxel phantoms is described, along with a numerical validation of this new functionality using a voxel phantom of the RANDO tissue-equivalent physical model.

To explore clinical characteristics and beta cell function in Chinese patients with newly diagnosed drug naive type 2 diabetes mellitus (T2DM) with different levels of serum triglyceride (TG). Patients with newly diagnosed T2DM (n = 624) were enrolled and divided into different groups according to levels of serum TG. All patients underwent oral glucose tolerance tests and insulin releasing tests. Demographic data, lipid profiles, glucose levels, and insulin profiles were compared between different groups. Basic insulin secretion function index (homeostasis model assessment for beta cell function index, HOMA-β), modified beta cell function index (MBCI), glucose disposition indices (DI), and early insulin secretion function index (insulinogenic index, IGI) were used to evaluate the beta cell function. Patients of newly diagnosed T2DM with hypertriglyceridemia were younger, fatter and had worse lipid profiles, glucose profiles, and high insulin levels than those with normal TG. There is no difference in early phase insulin secretion among groups of newly diagnosed T2DM patients with different TG levels. The basal beta cell function (HOMA-β and MBCI) initially increased along rising TG levels and then decreased as the TG levels rose further. The insulin sensitivity was relatively high in patients with a low level of TG and low with a high level of TG. Hypertriglyceridemia influences clinical characteristics and β cell function of Chinese patients with newly diagnosed T2DM. A better management of dyslipidemia may, to some extent, reduce the effect of lipotoxicity, thereby improving glucose homeostasis in patients with newly diagnosed T2DM.

Responses of 2369 newly licensed registered nurses from 3 generational cohorts-Baby Boomers, Generation X, and Generation Y-were studied to identify differences in their characteristics, work-related experiences, and attitudes. These responses revealed significant differences among generations in: job satisfaction, organizational commitment, work motivation, work-to-family conflict, family-to-work conflict, distributive justice, promotional opportunities, supervisory support, mentor support, procedural justice, and perceptions of local job opportunities. Health organizations and their leaders need to anticipate intergenerational differences among newly licensed nurses and should provide for supportive working environments that recognize those differences. Orientation and residency programs for newly licensed nurses should be tailored to the varying needs of different generations. Future research should focus on evaluating the effectiveness of orientation and residency programs with regard to different generations so that these programs can be tailored to meet the varying needs of newly licensed nurses at the start of their careers.

2006-01-01

Newly installed in the Laboratory for Detection of Irradiated Food at the beginning of 2005 Pulsed PhotoStimulated Luminescence method (PPSL) is described. Methodology of the PPSL examination of food is simple: the analysed sample is dispensed into a Petri dish in a thin layer and placed into a sample chamber. the sample is exposed to pulsed laser infra-red light emitted by an array of diodes (IR LEDs). The PPSL signal produced in the system by luminescence released from photostimulated mineral debris of the sample is stored by a photomultiplier and the created numerical signal transmitted to the PC. it has been found, that screening by means of the PPSL apparatus is easy, effective and inexpensive. The method provides the fastest way to gain results whether food product is irradiated

Program for the evaluation of a high-level waste repository which is conceptually modeled. During the last few years, programs developed with the aid of AMBER and GoldSim by which nuclide transports in the near- and far-field of a repository as well as transport through the biosphere under various normal and disruptive release scenarios could be modeled and evaluated, have been continuously demonstrated. To show its usability, as similarly done for the natural groundwater flow scheme, influence of a possible disruptive event on a nuclide release behavior from an HLW repository system caused naturally due to an earthquake has been investigated and illustrated with the newly developed GoldSim program

Huntington’s disease (HD) is a fatal, genetic, neurodegenerative disorder characterized by deficits in motor and cognitive function. Here, we have quantitatively characterized motor deficiencies and dopamine release dynamics in transgenic HD model rats. Behavioral analyses were conducted using a newly-developed force-sensing runway and a previously-developed force-plate actometer. Gait disturbances were readily observed in transgenic HD rats at 12 to 15 months of age. Additionally, dopamine system challenge by ip injection of amphetamine also revealed that these rats were resistant to the expression of focused stereotypy compared to wild-type controls. Moreover, dopamine release, evoked by the application of single and multiple electrical stimulus pulses applied at different frequencies, and measured using fast-scan cyclic voltammetry at carbon-fiber microelectrodes, was diminished in transgenic HD rats compared to age-matched wild-type control rats. Collectively, these results underscore the potential contribution of dopamine release alterations to the expression of motor impairments in transgenic HD rats. PMID:22418060

Environmentally sensitive hydrogels as one of the most potential drug delivery systems have gained considerable interest in recent years. In the present study, we synthesized a newly temperature-responsive composite hydrogel based on attapulgite (ATP) and poly (N-isopropylacrylamide) (PNIPAM) as the localized drug carriers for drug delivery. The as-prepared ATP/PNIPAM hydrogel has large aperture which significantly improved the quantity of adsorption of drugs, exhibiting the excellent properties of drug release. The scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and X-ray diffraction (XRD) were used to characterize the ATP/PNIPAM. The swelling/deswelling behaviors and the release of ciprofloxacin lactate were studied. When the temperature was below the low critical solution temperature (LCST), the swelling property of hydrogels was excellent and the swelling rate was large. And, the drug release rate increased with the increase of the content of attapulgite in the composite hydrogel when it was put in the buffer solution (pH 7.38) at 37.0 °C. Therefore, the composite hydrogels might be very useful for its application in biomedical fields. - Highlights: • Attapulgite/N-isopropylacrylamide hydrogels were synthesized and characterized. • The swelling property of hydrogels was excellent when temperature was below 34.0 °C. • The composite hydrogels were used for the release of ciprofloxacin lactate. • The drug release rate increased with the increase of the content of attapulgite.

Intravenous chemotherapy is an important mean for the treatment of cancers. Infusion phlebitis (Ph) is a common and acute complication of chemotherapy. The frequency of Ph is about 70% in patients undergoing chemotherapeutic management. It can induce the pain, increase the risk of thrombophlebitis, lead to incomplete follow-up, and thereby, affect the patient’s health status. Respecting the great importance of these issues, it is essential to prevent Ph. This study conducted to determine the effect of external use of Sesame Oil (SO) in the prevention of Ph. Sixty patients with colon or rectum cancer, who admitted for chemotherapeutic management, enrolled in clinical trial and were randomly divided into two equal groups: Control and Intervention. Ten drops of SO was applied twice a day for 14 days externally in intervention group, whereas the control group received nothing. Incidence and grade of Ph was measured in both groups. Data was analyzed through independent t-test, Χ2, Fisher’s exact test, Mann-Whitney, and Lagrange survival using SPSS 16. The incidence of Ph was 10% and 80% in intervention group and control group, respectively.There was a significant difference between two groups (p < 0.05). Ph was 8 times more frequent in control group (R R = 8; AR R = 70%). In addition, there was statistically significant difference between the grade and incidence of Ph with SO and control group (p < 0.05). According to these results, it seems that external use of SO is effective, safe and well-tolerated for prophylaxis from Ph. Therefore, it can be suggested as a selected prevention method for reducing the complication. PMID:24250538

Genetic improvement of sesame (Sesamum indicum, L). using gamma ray Induced mutations in cross breeding has been in progress. From prior studies a cross between two induced mutants mut 1 and Mut 2 and the exotic line N.A.121, two true breeding lines designated as Inshas 11 and Inshas 12 were established in F6 generation with morphological changes and desired characters i.e. three capsules / leaf axll, long capsule seed size increased and non-branched and branched types. In the present study evaluation of the two ne lines for agronomic characters including seed yield and oil content, field experiments were conducted at Nucl. Res, Center, Inshas during three successive seasons (1994,1995 and 1996). In each season, the experiment included two new lines and the best local variety Giza 32 using randomized complete block design with three replicates. The obtained results over the three seasons indicated that flowering date was earlier 13 and 6 days for inshas 11 and inshas 12, respectively, as compared to Giza 32. First capsule height was 34 cm and 17 cm lower than Giza 32 for inshas 11 and inshas 12, respectively. Marked reduction for plant height was only obtained for inshas 12. However, a considerable increase for fruiting zone length was only found for inshas 11

DPCs preferentially involve proteins of the nuclear matrix, the site of replication and transcription. To elucidate the relationship with replication, the formation and repair of DPCs has been studied in newly replicated DNA. Log-phase V79 cells were pulsed with /sup 3/H-TdR (10-20 μCi/ml) for 30-90 sec at 22 0 followed by up to a 60 min chase at 37 0 . Irradiation (0-100 Gy) immediately after the pulse increases the labeled DNA in DPCs with a dose-dependence that is unaffected by the initial level of labeled DPC or by chase time. When cells are irradiated before the pulse, DNA synthesis is inhibited; however, release of pulse-labeled DPCs appears normal. The data suggest that during replication, DNA is cross-linked to (matrix) protein, contributing to background DPCs

Full Text Available This study was carried out to evaluate the genetic diversity of the breeding lines isolated from the sesame landraces. Seventy genotypes were evaluated in randomized complete block design with two replications in 2008. The results showed that there were significant differences among the genotypes for all of the studied traits such as days to maturity, plant height and seed yield. There was no difference between the phenotypic and genetic coefficients of variations for most of the traits, thus it was concluded that the majority of their observed variations was due to the genetic factors. The grain yield of the genotypes ranged from 1089 to 4650 kg/ha. One of the breeding line isolated from Birjand landrace had the highest mean of days to maturity (170 days and Yekta genotype had the lowest mean for this trait (118 days. The range of plant height among genotypes was 123 to 179 cm and the mean of capsule per plant was ranged from 46 to 181. Branches per plant had the highest broad-sense heritability (81.1 % and the estimated broad-sense heritability for grain yield was 75.5%. Cluster analysis classified the genotypes in three distinct groups and there were significant differences among these groups for all of the traits, except days to maturity. Genotypes classified in the second group had the most capsule per plant and grain yield and they can be used for genetic improvement of this trait. Meanwhile genotypes of the first group can be used for genetic improvement of plant height and branches per plant.

Full Text Available Abstract Background The immune defects occurring in chronic lymphocytic leukemia are responsible for the frequent occurrence of infections and autoimmune phenomena, and may be involved in the initiation and maintenance of the malignant clone. Here, we evaluated the quantitative defects of newly produced B and T lymphocytes. Methods The output of B and T lymphocytes from the production and maturation sites was analyzed in chronic lymphocytic leukemia patients and healthy controls by quantifying kappa-deleting recombination excision circles (KRECs and T-cell receptor excision circles (TRECs by a Real-Time PCR assay that simultaneously detects both targets. T-lymphocyte subsets were analyzed by six-color flow cytometric analysis. Data comparison was performed by two-sided Mann-Whitney test. Results KRECs level was reduced in untreated chronic lymphocytic leukemia patients studied at the very early stage of the disease, whereas the release of TRECs+ cells was preserved. Furthermore, the observed increase of CD4+ lymphocytes could be ascribed to the accumulation of CD4+ cells with effector memory phenotype. Conclusions The decreased number of newly produced B lymphocytes in these patients is likely related to a homeostatic mechanism by which the immune system balances the abnormal B-cell expansion. This feature may precede the profound defect of humoral immunity characterizing the later stages of the disease.

A program for the safety assessment and performance evaluation of a low- and intermediate-level radioactive waste (LILW) repository system has been developed. Utilizing GoldSim (GoldSim, 2006), the program evaluates nuclide release and transport into the geosphere and biosphere under various disruptive natural and manmade events and scenarios that can occur after a waste package failure. We envisaged and illustrated these events and scenarios as occurring after the closure of a hypothetical LILW repository, and they included the degradation of various manmade barriers, pumping well drilling, and natural disruptions such as the sudden formation of a preferential flow pathway in the far-field area of the repository. Possible enhancement of nuclide transport facilitated by colloids or chelating agents is also dealt with. We used the newly-developed GoldSim template program, which is capable of various nuclide release scenarios and is greatly suited for simulating a potential repository given the geological circumstances in Korea, to create the detailed source term and near-field release scheme, various nuclide transport modes in the far-field geosphere area, and the biosphere transfer. Even though all parameter values applied to the hypothetical repository were assumed, the illustrative results, particularly the probabilistic calculations and sensitivity studies, may be informative under various scenarios

quantitative and qualitative characteristics of sesame (Sesamum indicum L. in a low input cropping system was investigated. Materials and methods In order to evaluate the effects of simultaneous application of mycorrhiza and organic fertilizers on some quantitative and qualitative characteristics of sesame (Sesamum indicum L., an experiment was conducted based on randomized complete block design with three replications at Agricultural Research Farm, Ferdowsi University of Mashhad, Iran during growing season 2009-2010 growing season. Treatments were mycorrhiza (Glomus mosseae, mycorrhiza+compost, mycorrhiza+vermicompost, mycorrhiza+organic sulfural geranole, compost, vermicompost, Organic sulfural geranole and control (no fertilizer. Finally, data analysis was done using SAS 9.1 and means were compared by duncan’s multiple range test at 5% level of probability. Results and discussion The results showed that the effect of different organic and biological fertilizers were significant on seed yield. Seed yield significantly increased by using mycorrhiza in both condition of single and mixed with organic sulfural geranole and vermicompost compared to control treatment. Biological yield, in simultaneous application of vermicompost and organic sulfural geranole with mycorrhiza increased significantly compared to separate use of these fertilizers. All study organic fertilizers with mycorrhiza had significant effect on increasing oil content of sesame. Seed oil increased in simultaneous application of mycorrhiza and each of compost, vermicompost and organic sulfural geranole compared to separate application of mycorrhiza 12, 13 and 10 percentages, respectively. It seems that mycorrhiza and organic fertilizers improved quantitative and qualitative characteristics of sesame due to provide better conditions to absorption and transportation of nutrient to the plant (Hawkes et al., 2008. Conclusion In general, the results showed that the simultaneous use of ecological inputs can improve

Apparent ileal digestibility (AID) of diets containing sesame expeller (SE) and soya bean meal (SBM) was determined using 15 piglets (Genetiporc(®)), weaned at 17 ± 0.4 days with average body weight of 6.4 ± 0.7 kg (Fertilis 20 × G Performance, Genetiporc(®), PIC México, Querétaro, México). Piglets were randomly assigned to three treatments: (i) a reference diet with casein as the sole protein source; (ii) a mixed diet of casein-SE; and (iii) a mixed diet of casein-SBM. The chemical composition of SE and SBM was determined, and AID and standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AAs) were determined for each protein source. SE contained greater quantities of ether extract, neutral detergent fibre, phytic acid, methionine and arginine than SBM. Lysine and proline contents and trypsin inhibitor activity were higher in SBM than in SE. The AID and SID of CP and AA (except for lysine and proline) were similar in SE and SBM. The AID of lysine and proline was higher in SBM than in SE (p < 0.05), and the SID of proline was higher in SE than in SBM (p < 0.05). These findings indicate that SE is an appropriate alternative protein source for early weaned pigs. Journal of Animal Physiology and Animal Nutrition © 2014 Blackwell Verlag GmbH.

Full Text Available Climate information is recognized as a powerful tool to reduce the effect of climate risk and uncertainty on crop production and increase the resilience and the adaptive capacity of farmers in semi-arid zones. This paper estimates farmers’ willingness to pay (WTP for climate information within cowpea and sesame value chains in Northern Burkina Faso. The study used the contingent valuation method for a monetary valuation of farmers’ preferences for climate information. Data were collected using a structured questionnaire from 170 farmers. The study found that 63% of respondents were willing to pay for climate information services (CIS such as seasonal climate forecast (SCF, decadal climate information (10-DCI, daily climate information (1-DCI and agro-advisories. The predicted value for the WTP was XOF 3496 for SCF, XOF 1066 for 10-DCI, XOF 1985 for 1-DCI and XOF 1628 for agro-advisories. The study also showed that several socioeconomic and motivation factors have greater influence on farmers’ WTP for CIS. These included the gender, age, education of the farm head and the awareness of farm head to climate information. The outcomes of this paper should support policy makers to better design an efficient mechanism for the dissemination of climate information to improve the adaptive capacity of farmers to climate risks in Burkina Faso.

This report identifies and evaluates three options for treating newly generated liquid waste at the Idaho Nuclear Technology and Engineering Center of the Idaho National Engineering and Environmental Laboratory. The three options are: (a) treat the waste using processing facilities designed for treating sodium-bearing waste, (b) treat the waste using subcontractor-supplied mobile systems, or (c) treat the waste using a special facility designed and constructed for that purpose. In studying these options, engineers concluded that the best approach is to store the newly generated liquid waste until a sodium-bearing waste treatment facility is available and then to co-process the stored inventory of the newly generated waste with the sodium-bearing waste. After the sodium-bearing waste facility completes its mission, two paths are available. The newly generated liquid waste could be treated using the subcontractor-supplied system or the sodium-bearing waste facility or a portion of it. The final decision depends on the design of the sodium-bearing waste treatment facility, which will be completed in coming years.

Raloxifene hydrochloride (RLX) is a selective estrogen receptor modulator which is orally used for treatment of osteoporosis and prevention of breast cancer. The drug has low aqueous solubility and bioavailability. The aim of the present study is to formulate and characterize oil-in-water microemulsion systems for oral delivery of RLX. To enhance the drug aqueous solubility, microemulsion based on sesame oil was prepared. Sesame oil and Tween 80 were selected as the drug solvent oil and surfactant, respectively. In the first and second formulations, Edible glycerin and Span 80 were applied as co-surfactant, respectively. Pseudo-ternary phase diagrams showed that the best surfactant/co-surfactant ratios in the first and second formulations were 4:1 and 9:1, respectively. The particle size of all free drug-loaded and drug loaded samples were in the range of 31.25 ± 0.3 nm and 60.9 ± 0.1 nm, respectively. Electrical conductivity coefficient and refractive index of all microemulsion samples confirmed the formation of oil-in-water type of microemulsion. In vitro drug release profile showed that after 24 hours, 46% and 63% of the drug released through the first formulation in 0.1% (w/v) Tween 80 in distilled water as a release medium and phosphate buffer solution (PBS) at pH = 5.5, respectively. These values were changed to 57% and 98% for the second formulation. Results confirmed that the proposed microemulsion system containing RLX could improve and control the drug release profile in comparison to conventional dosage form.

One hundred and sixty-three cultivars of annual oilseed crops, developed using induced mutations, have been officially approved and released for cultivation in 26 countries. The maximum number of cultivars have been released in soybean (58), followed by groundnut (44), sesame (16), linseed (15), rapeseed (14), Indian mustard (8), castorbean (4), white mustard (3) and sunflower (1). The majority (118 of 163) of the cultivars have been developed as direct mutants and 45 of 163 by using the induced mutants in a crossing programme. While in soybean 53 out of 58 cultivars were selected as direct mutants, in groundnut 22 from 44 were developed after hybridization. Eighty-three cultivars were developed directly by exposing seeds to gamma or X-rays. Attempts have been made to infer the successful dose range, defined as the range which led to the development, registration and release of the maximum number of mutant cultivars for gamma and X-rays. The successful dose ranges in Gy for the main oilseed crops are: soybean 100-200, groundnut 150-250, rapeseed 600-800, Indian mustard 700 and sesame 100-200. The main characteristics of the new cultivars, besides higher yield, are altered plant type, early flowering and maturity and oil content. Mutants altering fatty acid composition have been isolated in soybean, rapeseed, sunflower, linseed and minor oil crops. New cultivars having altered fatty acid composition have been released in rapeseed, sunflower and linseed. The latter, previously grown for non-edible oil, has been converted to a new edible oil crop. (author)

There have been many studies reporting that newly formed bone around implants is spongy bone. However, although the morphology is reported as being like spongy bone, it is difficult to discriminate whether the bone quality of newly formed bone appears similar to osteoid or cortical bone; therefore, evaluation of bone quality is required. The aims of this study were to measure the bone mineral density (BMD) values of newly formed bone around implants after 4, 8, 16, 24 and 48 weeks, to represent these values on three-dimensional color mapping (3Dmap), and to evaluate the change in bone quality associated with newly formed bone around implants. The animal experimental protocol of this study was approved by the Ethics Committee for Animal Experiments of our University. This experiment used 20 surface treatment implants (Ti-6Al-4V alloy: 3.1 mm in diameter and 30.0 mm in length) by grit-blasting. They were embedded into surgically created flaws in femurs of 20 New Zealand white rabbits (16 weeks old, male). The rabbits were sacrificed with an ear intravenous overdose of pentobarbital sodium under general anesthesia each period, and the femurs were resected. We measured BMD of newly formed bone around implants and cortical bone using Micro-CT, and the BMD distribution map of 3Dmap (TRI/3D Bon BMD, Ratoc System Engineering). The BMD of cortical bone was 1,026.3±44.3 mg/cm 3 at 4 weeks, 1,023.8±40.9 mg/cm 3 at 8 weeks, 1,048.2±45.6 mg/cm 3 at 16 weeks, 1,067.2±60.2 mg/cm 3 at 24 weeks, and 1,069.3±50.7 mg/cm 3 at 48 weeks after implantation, showing a non-significant increase each period. The BMD of newly formed bone around implants was 296.8±25.6 mg/cm 3 at 4 weeks, 525.0±72.4 mg/cm 3 at 8 weeks, 691.2±26.0 mg/cm 3 at 16 weeks, 776.9±27.7 mg/cm 3 at 24 weeks, and 845.2±23.1 mg/cm 3 at 48 weeks after implantation, showing a significant increase after each period. It was revealed that the color scale of newly formed bone was Low level at 4 weeks, and then it

This paper reports the findings from a study of newly qualified nurses and which subjects the nurses regarded as the most important in order to be able to live up to the requirements of clinical practice, and how they experience their potential for developing practical and moral skills, after the decrease in practical training. A qualitative approach guided the research process and the analysis of the data. The data was collected by participant observation and qualitative interviews with four nurses as informants. The conclusions made in this study are based on the statements and the observations of the newly qualified nurses. Our findings are discussed in relation to the Aristotelian concept and other relevant literature. The main message is that the newly qualified nurses did not feel equipped when they finished their training. This could be interpreted as a direct consequence of the decrease in practical training. Our study also underlines that the way nursing theory is perceived and taught is problematic. The interviews revealed that the nurses think that nursing theories should be applied directly in practice. This misunderstanding is probably also applicable to the teachers of the theories.

To advance evidence on newly graduated nurses' use of knowledge sources. Clinical decisions need to be evidence-based and understanding the knowledge sources that newly graduated nurses use will inform both education and practice. Qualitative studies on newly graduated nurses' use of knowledge sources are increasing though generated from scattered healthcare contexts. Therefore, a metasynthesis of qualitative research on what knowledge sources new graduates use in decision-making was conducted. Meta-ethnography. Nineteen reports, representing 17 studies, published from 2000-2014 were identified from iterative searches in relevant databases from May 2013-May 2014. Included reports were appraised for quality and Noblit and Hare's meta-ethnography guided the interpretation and synthesis of data. Newly graduated nurses' use of knowledge sources during their first 2-year postgraduation were interpreted in the main theme 'self and others as knowledge sources,' with two subthemes 'doing and following' and 'knowing and doing,' each with several elucidating categories. The metasynthesis revealed a line of argument among the report findings underscoring progression in knowledge use and perception of competence and confidence among newly graduated nurses. The transition phase, feeling of confidence and ability to use critical thinking and reflection, has a great impact on knowledge sources incorporated in clinical decisions. The synthesis accentuates that for use of newly graduated nurses' qualifications and skills in evidence-based practice, clinical practice needs to provide a supportive environment which nurtures critical thinking and questions and articulates use of multiple knowledge sources. © 2016 John Wiley & Sons Ltd.

Full Text Available The development and characterization of novel macromolecular conjugates of ampicillin using branched biodegradable polymers has been described in this study. The conjugates have been prepared coupling the β-lactam antibiotic with branched polymer matrices based on the natural oligopeptide core. The cyto- and genotoxicity of the synthesized polymers were evaluated with a bacterial luminescence test, two protozoan assays and Salmonella typhimurium TA1535. The presence of a newly formed covalent bond between the drug and the polymer matrices was confirmed by 1H-NMR and FTIR studies. A drug content (15.6 and 10.2 mole % in the macromolecular conjugates has been determined. The obtained macromolecular products have been subjected to further in vitro release studies. The total percentage of ampicillin released after 21 days of incubation was nearly 60% and 14% and this resulted from the different physicochemical properties of the polymeric matrices. This is the first report on the application of branched biodegradable polymeric matrices for the covalent conjugation of ampicillin. The obtained results showed that the synthesized macromolecular drug-conjugates might slowly release the active drug molecule and improve the pharmacokinetics of ampicillin.

Mast cells play an important role in the pathological development of many inflammatory and allergic diseases and inhibition of mast cell activation is a potential target for therapeutic intervention. Therefore, the effect of the novel ascomycin macrolactam derivative SDZ ASM 981 on Fc epsilonRI-mediated activation of rat basophilic leukemia (RBL) cells, as a model for mast cell activation, was investigated. First, the ability to inhibit different mast cell immunophilins in vitro was tested. Using recombinant macrophilin-12 (FKBP-12), inhibition of rotamase activity with an IC50 of approximately 6 nM was observed. The rotamase activity of cyclophilin A (18 kDa) was not affected. Secondly, the effect of SDZ ASM 981 on Fc epsilonRI-mediated mast cell activation was investigated in the RBL cell model. SDZ ASM 981 inhibited exocytosis of preformed mediators (e.g. serotonin) with an IC50 of approximately 30 nM. Transcription and release of newly synthesized mediators (e.g. TNF-alpha) was inhibited with an IC50 of approximately 100 nM. The inhibitory effect of SDZ ASM 981 was antagonized by rapamycin. We conclude that SDZ ASM 981 is a potent inhibitor of Fc epsilonRI-mediated activation of mast cells in vitro. The mechanism of action involves formation of (calcineurin) inhibitory complexes with macrophilins. We suggest that this inhibitory action on mast cells might contribute to the antiinflammatory effect of SDZ ASM 981 observed in vivo (e.g. in aptopic dermatitis and psoriasis).

In this work, lignite, a low-grade coal, was modified using the solid-phase activation method with the aid of a Pd/CeO 2 nanoparticle catalyst to improve its pore structure and nutrient absorption. Results indicate that the adsorption ability of the activated lignite to NO 3 - , NH 4 + , H 2 PO 4 - , and K + was significantly higher than that of raw lignite. The activated lignite was successfully combined with the polymeric slow-release fertilizer, which exhibits typical slow-release behavior, to prepare the super large granular activated lignite slow-release fertilizer (SAF). In addition to the slow-release ability, the SAF showed excellent water-retention capabilities. Soil column leaching experiments further confirmed the slow-release characteristics of the SAF with fertilizer nutrient loss greatly reduced in comparison to traditional and slow-release fertilizers. Furthermore, field tests of the SAF in an orchard showed that the novel SAF was better than other tested fertilizers in improve the growth of young apple trees. Findings from this study suggest that the newly developed SAF has great potential to be used in apple cultivation and production systems in the future.

This paper presents a study that explores how newly qualified registered nurses experience their leadership role in the ward-based nursing care team. A nurse's clinical leadership affects the quality of care provided. Newly qualified nurses experience difficulties during the transition period from student to qualified professional and find it challenging to lead nursing care. Twelve nurses were interviewed and the transcribed texts analysed using qualitative content analysis to assess both manifest and latent content. Five themes were identified: feeling stranded; forming well-functioning teams; learning to lead; having the courage, strength, and desire to lead; and ensuring appropriate care. The findings indicate that many factors limit nurses' leadership but some circumstances are supportive. The leadership prerequisites for newly registered nurses need to improve, emphasizing different ways to create a supportive atmosphere that promotes professional development and job satisfaction. To increase nurse retention and promote quality of care, nurse managers need to clarify expectations and guide and support newly qualified nurses in a planned way. © 2013 John Wiley & Sons Ltd.
People newly in love are more responsive to positive feedback.

Brown, Cassandra L; Beninger, Richard J

2012-06-01

Passionate love is associated with increased activity in dopamine-rich regions of the brain. Increased dopamine in these regions is associated with a greater tendency to learn from reward in trial-and-error learning tasks. This study examined the prediction that individuals who were newly in love would be better at responding to reward (positive feedback). In test trials, people who were newly in love selected positive outcomes significantly more often than their single (not in love) counterparts but were no better at the task overall. This suggests that people who are newly in love show a bias toward responding to positive feedback, which may reflect a general bias towards reward-seeking.

Background Studying the dispersal range of Anopheles sinensis is of major importance for understanding the transition from malaria control to elimination. However, no data are available regarding the dispersal range of An. sinensis in China. The aim of the present study was to study the dispersal range of An. sinensis and provide the scientific basis for the development of effective control measures for malaria elimination in China. Methodology/Principal Findings Mark-Release-Recapture (MRR) experiments were conducted with 3000 adult wild An. sinensis in 2010 and 3000 newly emerged wild An. sinensis in 2011 in two villages of Yongcheng City in Henan Province. Marked An. sinensis were recaptured daily for ten successive days using light traps. The overall recapture rates were 0.83% (95% CI, 0.50%∼1.16%) in 2010 and 1.33% (95% CI, 0.92%∼1.74%) in 2011. There was no significant difference in the recapture rates of wild An. sinensis and newly emerged An. sinensis. The majority of An. sinensis were captured due east at study site I compared with most in the west at study site II. Eighty percent and 90% of the marked An. sinensis were recaptured within a radius of 100 m from the release point in study site I and II, respectively, with a maximum dispersal range of 400 m within the period of this study. Conclusions/Significance Our results indicate that local An. sinensis may have limited dispersal ranges. Therefore, control efforts should target breeding and resting sites in proximity of the villages. PMID:23226489

In the United States, latent tuberculosis infection (LTBI) detection in correctional settings is a public health priority. Interferon gamma release assay (IGRA)-based LTBI screening was introduced in New York City jails in 2011 to 2012, replacing historically used tuberculin skin testing (TST), which was associated with substantial incomplete screening rates. This retrospective, cross-sectional study evaluated LTBI screening outcomes and correlates of positivity in 40,986 persons newly incarcerated in 2011 to 2013. Of 35,090 eligible patients tested (96.4%), final results were 6.3% positive, 93.4% negative, and 0.2% indeterminate. In multivariable regression modeling, sex, age, race/ethnicity, nativity, marital status, prior jail incarceration, and HIV status were correlated with positivity. IGRA-based screening yielded high screening and low indeterminate test rates and may be recommended in correctional and other settings where TST is currently used.

Sklet, Snorre; Vinnem, Jan Erik; Aven, Terje

2006-01-01

This paper presents results from a case study carried out on an offshore oil and gas production platform with the purpose to apply and test BORA-Release, a method for barrier and operational risk analysis of hydrocarbon releases. A description of the BORA-Release method is given in Part I of the paper. BORA-Release is applied to express the platform specific hydrocarbon release frequencies for three release scenarios for selected systems and activities on the platform. The case study demonstrated that the BORA-Release method is a useful tool for analysing the effect on the release frequency of safety barriers introduced to prevent hydrocarbon releases, and to study the effect on the barrier performance of platform specific conditions of technical, human, operational, and organisational risk influencing factors (RIFs). BORA-Release may also be used to analyse the effect on the release frequency of risk reducing measures

To evaluate exercise recommendations in patients newly diagnosed with fibromyalgia. A retrospective chart review. A public university rheumatology clinic. Patients newly diagnosed with fibromyalgia (N = 122). Frequency and type of exercise recommendations. The mean (standard deviation) age of these patients with fibromyalgia was 45 ± 12 years; 91% were women. Exercise was recommended as part of the documented treatment plan in 47% of these patients (57/122); only 3 patients had a documented contraindication for exercise. Aquatic exercise was most frequently recommended (56% [32/57]), followed by combined aquatic-aerobic exercise (26% [15/57]), and, infrequently, aerobic exercise only (5% [3/57]); only 7% of these patients (4/57) were referred for physical therapy. The primary method of communication was verbal discussion (94% [54/57]). Although there is well-documented evidence that exercise is beneficial for patients with fibromyalgia, we found that less than half of patients with newly diagnosed fibromyalgia in our study were provided recommendations to initiate an exercise program as part of their treatment plan. Further investigation of these findings are warranted, including evaluation of other university and community rheumatology practices as well as that of other physicians caring for patients with fibromyalgia. However, our findings indicate that there appears to be an opportunity to provide more specific and practical education regarding the implementation of an exercise regimen for patients with newly diagnosed fibromyalgia. Physiatrists may be particularly well suited to manage the exercise component of patients with fibromyalgia because of their specialized training in exercise prescription.

Full Text Available In order to understand the effect of plant density and different fertilizers on sesame (Sesamum indicum L. production, an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications. The experimental treatments were fertilizers in four levels (cow manure (30 t.ha-1, municipal compost (30 t.ha-1, chemical fertilizer (250 kg ammonium phosphate + 100 kg urea and control (no-fertilizer and plant density in four levels (20, 30, 40 and 50 plant.m-2. The results showed that all treatments increased the plant height, number of capsule per plant, plant biomass, seed yield, seed weight and number of seed per plant compared to control, significantly. The highest amount of the traits was obtained in manure treatment. The seed yield was increased by increasing plant density, but decreased the plant height, number of capsule per plant, plant biomass, seed yield and weight and number of seed per plant, significantly. 1000-seed weight, harvest index and weight of seed per capsule had no affected by treatments. Our result indicated that the density of 40 plant.m-2 among using manure was the most appropriate of cropping pattern in our experiment.

This study was conducted to investigate the preventive effects of different kanjangs (Korean soy sauces), including acid-hydrolyzed soy sauce (AHSS), fermented soy sauce (FSS), and fermented sesame sauce (FSeS), on 2% dextran sulfate sodium (DSS)-induced ulcerative colitis in C57BL/6J mice. The fermented sauces, particularly FSeS, significantly suppressed DSS-induced body weight loss, increased colon length, and decreased colon weight/length ratios. Histological observations suggested that the fermented sauces prevented edema, mucosal damage, and the loss of crypts induced by DSS compared to the control mice and animals fed AHSS. FSeS and FSS decreased the serum levels of tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin (IL)-6, and IL-17α. mRNA expression of these cytokines as well as that of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in colon mucosa was also inhibited by the two sauces. Our results suggest that fermented sauces, especially FSeS, exert an anticolitic effect partially by reducing the serum levels of proinflammatory cytokines and inhibiting the mRNA expression of these factors in the colon tissue of mice treated with DSS. However, AHSS did not protect against DSS-induced colitis. In addition, low-dose treatment (4 mL/kg) with the fermented sauces resulted in greater anticolitic effects than consumption of a high quantity (8 mL/kg) of the sauces.
Mitochondrial nucleoid clusters protect newly synthesized mtDNA during Doxorubicin- and Ethidium Bromide-induced mitochondrial stress

Energy Technology Data Exchange (ETDEWEB)

Mitochondrial DNA (mtDNA) is compacted in ribonucleoprotein complexes called nucleoids, which can divide or move within the mitochondrial network. Mitochondrial nucleoids are able to aggregate into clusters upon reaction with intercalators such as the mtDNA depletion agent Ethidium Bromide (EB) or anticancer drug Doxorobicin (DXR). However, the exact mechanism of nucleoid clusters formation remains unknown. Resolving these processes may help to elucidate the mechanisms of DXR-induced cardiotoxicity. Therefore, we addressed the role of two key nucleoid proteins; mitochondrial transcription factor A (TFAM) and mitochondrial single-stranded binding protein (mtSSB); in the formation of mitochondrial nucleoid clusters during the action of intercalators. We found that both intercalators cause numerous aberrations due to perturbing their native status. By blocking mtDNA replication, both agents also prevented mtDNA association with TFAM, consequently causing nucleoid aggregation into large nucleoid clusters enriched with TFAM, co-existing with the normal nucleoid population. In the later stages of intercalation (> 48 h), TFAM levels were reduced to 25%. In contrast, mtSSB was released from mtDNA and freely distributed within the mitochondrial network. Nucleoid clusters mostly contained nucleoids with newly replicated mtDNA, however the nucleoid population which was not in replication mode remained outside the clusters. Moreover, the nucleoid clusters were enriched with p53, an anti-oncogenic gatekeeper. We suggest that mitochondrial nucleoid clustering is a mechanism for protecting nucleoids with newly replicated DNA against intercalators mediating genotoxic stress. These results provide new insight into the common mitochondrial response to mtDNA stress and can be implied also on DXR-induced mitochondrial cytotoxicity. - Highlights: • The mechanism for mitochondrial nucleoid clustering is proposed. • DNA intercalators (Doxorubicin or Ethidium Bromide) prevent TFAM

High biocompatibility, outstanding electrochemical responsiveness, inertness, and transparency make diamond-based multiarrays (DBMs) first-rate biosensors for in vitro detection of electrochemical and electrical signals from excitable cells together, with potential for in vivo applications as neural interfaces and prostheses. Here, we will review the electrochemical and physical properties of various DBMs and how these devices have been employed for recording released neurotransmitter molecules and all-or-none action potentials from living cells. Specifically, we will overview how DBMs can resolve localized exocytotic events from subcellular compartments using high-density microelectrode arrays (MEAs), or monitoring oxidizable neurotransmitter release from populations of cells in culture and tissue slices using low-density MEAs. Interfacing DBMs with excitable cells is currently leading to the promising opportunity of recording electrical signals as well as creating neuronal interfaces through the same device. Given the recent increasingly growing development of newly available DBMs of various geometries to monitor electrical activity and neurotransmitter release in a variety of excitable and neuronal tissues, the discussion will be limited to planar DBMs.
Characteristics of a newly designed electrolyser to enrich tritium in environmental water

A newly designed electrolytic device to enrich tritium in environmental water is proposed. This device is composed of a solid polymer electrolytic film (SPE film) and porous, dimensionally stable electrodes (DSE). In our design a platinum mesh was inserted between the SPE film and the anode DSE so that the device can be easily disassembled and the used SPE film can be replaced with a new one after each use. A thin gold plate with a number of minute holes in it is used as current collector in both electrodes allowing the electrolytic gas to be released progressively. An electrolytic current of 6A was passed through the device to obtain a volume reducing factor of five by keeping a temperature of water both at 2degC or lower. After that, our device achieved a tritium recovery factor of 0.836±0.021 (n=4). Such a value is greater than the value obtained using a commercially available apparatus operated under the same experimental conditions. It is thought that this greater efficiency depends on the difference between electrolytic temperature produced in our device and the temperature in the commercially available one. (author)
Possible origin of Saturn's newly discovered outer ring

International Nuclear Information System (INIS)

Moehlmann, D.

1986-01-01

Within a planetogonic model the self-gravitationally caused formation of pre-planetary and pre-satellite rings from an earlier thin disk is reported. The theoretically derived orbital radii of these rings are compared with the orbital levels in the planetary system and the satellite systems of Jupiter, Saturn and Uranus. From this comparison it is concluded that at the radial position of Saturn's newly discovered outer ring an early pre-satellite ring of more or less evolved satellites could have existed. These satellites should have been disturbed in their evolution by the gravitation of the neighbouring massive satellite Titan. The comparison also may indicate similarities between the asteroidal belt and the newly discovered outer ring of Saturn

The present study assessed the level of dentists' knowledge regarding oral cancer in the city of São Paulo, Brazil. A questionnaire was used to compare the level of knowledge among newly graduated and senior clinicians. A total of 20,154 e-mails were correctly delivered to the dentists registered in the database of the Regional Dentistry Council of São Paulo, and 477 (2.36%) responses were received. This sample consisted of 84 newly graduated clinicians and 105 senior clinicians. For the statistical analysis, the chi-square test and the logistic regression analysis were performed with α = 0.05, and the results were described herein. According to their knowledge level, the results were statistically different between the groups, since 19% of the newly graduated clinicians were evaluated with knowledge grade A (excellent) in comparison to 6.7% of the senior clinicians. In spite of the results indicated that newly graduated clinicians' knowledge regarding oral cancer was 2.1 times higher, 34.5% of the professionals in this group had regular or poor knowledge on the subject, and several questions relating to clinical characteristics and risk factors indicated that there still exist some knowledge gaps, demonstrating that there is a need for further studies and information activities addressing oral cancer.

We analysed the effect of dantrolene (Dan) and five newly synthesized derivatives (GIFs) on Ca2+ release from the sarcoplasmic reticulum (SR) of mouse skeletal muscle.In intact muscles, GIF-0185 reduced the size of twitch contraction induced by electrical stimulation to the same extent as Dan. GIF-0082, an azido-functionalized Dan derivative, also inhibited twitch contraction, although the extent of inhibition was less than that of Dan and of GIF-0185.In skinned fibres, Dan inhibited Ca2+-induced Ca2+ release (CICR) under Mg2+-free conditions at room temperature. In contrast, GIF-0082 and GIF-0185 showed no inhibitory effect on CICR under the same conditions.Dan-induced inhibition of CICR was not affected by the presence of GIF-0082, whereas it was diminished in the presence of GIF-0185.GIF-0082 and GIF-0185 significantly inhibited clofibric acid (Clof)-induced Ca2+ release, as did Dan.Several Dan derivatives other than GIF-0082 and GIF-0185 showed an inhibitory effect on twitch tension but not on the CICR mechanism. All of these derivatives inhibited Clof-induced Ca2+ release.The magnitudes of inhibition of Clof-induced Ca2+ release by all Dan derivatives were well correlated with those of twitch inhibition. This supports the notion that the mode of Clof-induced opening of the RyR-Ca2+ release channel may be similar to that of physiological Ca2+ release (PCR).These results indicate that the difference in opening modes of the RyR-Ca2+ release channel is recognized by certain Dan derivatives.

Full Text Available The South African education and training system, through its policy of outcomesbased education and training, has made competency a national priority. In compliance to this national requirement of producing competent learners, the South African Nursing Council ( 1999 B require that the beginner professional nurse practitioners and midwives have the necessary knowledge, skills, attitudes and values which will enable them to render efficient professional service. The health care system also demands competent nurse practitioners to ensure quality in health care. In the light of competency being a national priority and a statutory demand, the research question that emerges is, how competent are the newly qualified registered nurses from a specific nursing college in clinical nursing education? A quantitative, non-experimental contextual design was used to evaluate the competence of newly qualified registered nurses from a specific nursing college. The study was conducted in two phases. The first phase dealt with the development of an instrument together with its manual through the conceptualisation process. The second phase focused on the evaluation of the competency of newly qualified nurses using the instrument based on the steps of the nursing process. A pilot study was conducted to test the feasibility of the items of the instrument. During the evaluation phase, a sample of twenty-six newly qualified nurses was selected by simple random sampling from a target population of thirty-six newly qualified registered nurses. However, six participants withdrew from the study. Data was collected in two general hospitals where the newly qualified registered nurses were working. Observation and questioning were used as data collection techniques in accordance with the developed instrument. Measures were taken to ensure internal validity and reliability of the results. To protect the rights of the participants, the researcher adhered to DENOSA’S (1998

This article is an anthropological archeology of Sicilian confectionery, from the prehistoric-like assemblage of sesame seeds and honey (giurgiulena) to the extravagant gelato di campagna and the baroque-rustic cassata. Sweets are analyzed as architectural constructions that rely on newly discovered ingredients and techniques to create edible edifices that amazed the eye as much as the palate. They emerge from their historical and social context and affirm themselves as moments of innovation in the culinary art. On a deeper level, the art of pasticceri bears the marks of an existential quest that constantly redefines man's symbolic relation to the forces and contrasts of life.

For 20 years, the Ministry of Health, Labour and Welfare (MHLW, formerly Ministry of Health and Welfare (MHW)) has been trying to increase transparency of the review process for approving reports in order to promote the rational use of newly approved drugs and medical devices. The first Summary Basis of Approval (SBA) was published by MHW in 1994. In 1999, evaluation reports were prepared by MHW and the Pharmaceuticals and Medical Devices Evaluation Center to make them available to the public. In 2005, a notice from the Chief Executive of the Pharmaceuticals and Medical Devices Agency (PMDA) made procedures for public release of information on reviewing applications for new drugs. In 2006, 90 review reports of newly approved drugs and eight medical devices were revealed on PMDA websites. The dissemination of information by the United States Food and Drug Administration (FDA) and that of the European Medicines Agency (EMA) were studied and compared with that of the MHLW and PMDA. While common technical documents (CTD) for new drugs and summary technical documents (STED) for new medical devices have been released by PMDA, such documents are not released by the FDA and EMA. The European Public Assessment Report (EAPR) summary for the public is an interesting questionnaire approach that uses the "What," "How" and "Why" format. Finally, future proposals for the next decade are also outlined.

Emotional cues can guide selective attention processes. However, emotional stimuli can both activate long-term memory representations reflecting general world knowledge and engage newly formed memory representations representing specific knowledge from the immediate past. Here, the self-completion feature of associative memory was utilized to assess the regulation of attention processes by newly-formed emotional memory. First, new memory representations were formed by presenting pictures depicting a person either in an erotic pose or as a portrait. Afterwards, to activate newly-built memory traces, edited pictures were presented showing only the head region of the person. ERP recordings revealed the emotional regulation of attention by newly-formed memories. Specifically, edited pictures from the erotic compared to the portrait category elicited an early posterior negativity and late positive potential, similar to the findings observed for the original pictures. A control condition showed that the effect was dependent on newly-formed memory traces. Given the large number of new memories formed each day, they presumably make an important contribution to the regulation of attention in everyday life.

BACKGROUND/OBJECTIVES This study was performed to investigate the in vitro antioxidant and cytoprotective effects of fermented sesame sauce (FSeS) against hydrogen peroxide (H2O2)-induced oxidative damage in renal proximal tubule LLC-PK1 cells. MATERIALS/METHODS 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl radical (•OH), and H2O2 scavenging assay was used to evaluate the in vitro antioxidant activity of FSeS. To investigate the cytoprotective effect of FSeS against H2O2-induced oxidative damage in LLC-PK1 cells, the cellular levels of reactive oxygen species (ROS), lipid peroxidation, and endogenous antioxidant enzymes including catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-px) were measured. RESULTS The ability of FSeS to scavenge DPPH, •OH and H2O2 was greater than that of FSS and AHSS. FSeS also significantly inhibited H2O2-induced (500 µM) oxidative damage in the LLC-PK1 cells compared to FSS and AHSS (P sauces, FSeS also significantly increased cellular CAT, SOD, and GSH-px activities and mRNA expression (P < 0.05). CONCULUSIONS These results from the present study suggest that FSeS is an effective radical scavenger and protects against H2O2-induced oxidative damage in LLC-PK1 cells by reducing ROS levels, inhibiting lipid peroxidation, and stimulating antioxidant enzyme activity.

Arsenic-contaminated groundwater is a world-wide environmental problem and threatens more than 100 million people living in delta areas of South, SE and East Asia. It is typically associated with reducing aquifers with organic-rich alluvial sediments, little thermal gradients, low sulfate concentrations, and slow flushing rates. Such conditions are typical for low-lying countries in Asian deltas; however, compared to Bangladesh, Cambodia has received far less attention. Upon reductive dissolution of Fe-(oxyhydr)oxides that adsorbed As, Fe and As are released into solution as dissolved Fe2+ and arsenate, respectively. Following the oxidation of dissolved Fe2+, newly-formed Fe-(oxyhydr)oxides adsorb As again. Thus, in anoxic waters, concentrations of As correlate with those of dissolved Fe2+. Fluctuating redox conditions in the aquifer are control As release, although inhibition of adsorption of arsenate and arsenite onto the Fe-(oxyhydr)oxides occurs when the concentrations of phosphate, bicarbonate, silicate, and/or organic matter become sufficiently high. Biogeochemical redox reactions of Fe result in significant isotope fractionation (e.g., Johnson et al., 2008). We hypothesized that magnitude of isotope fractionation of Fe in the aquifer sediments, reflecting repeated (incomplete) redox reactions of Fe, may be proportional to the amount of total As release. We aim to calibrate the As release from aquifer sediment by Fe isotope analysis. As a preliminary study, series of sediment samples were collected from the Mekong Delta, Cambodia, in September 2016. Based on measurements by XRF, ICP-AES and ICP-MS, concentrations of As varied significantly covering the range from 4.5 to 15.5 µg/g with a median value of 11 µg/g (higher than the average crustal value of 5 µg/g), and those of Fe is from 2.6 to 9.7 wt.% with a median value of 7.1 wt.%. Concentrations of As and Fe show positive correlation (R2 = 0.72), indicating an effective redox cycling of Fe and As as

Offiah, Gozie; Doherty, Eva

2018-03-01

The transition from medical student to doctor is an important milestone. The discovery that their time is no longer their own and that the demands of their job are greater than the time they have available is extremely challenging. At a recent surgical boot camp training programme, 60 first-year surgical trainees who had just completed their internship were invited to reflect on the lessons learnt regarding effective time management and to recommend tips for their newly qualified colleagues. They were asked to identify clinical duties that were considered urgent and important using the time management matrix and the common time traps encountered by newly qualified doctors. The surgical trainees identified several practical tips that ranged from writing a priority list to working on relationships within the team. These tips are generic and so applicable to all newly qualified medial doctors. We hope that awareness of these tips from the outset as against learning them through experience will greatly assist newly qualified doctors. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Size and frequency of gaps in newly synthesized DNA of xeroderma pigmentosum human cells irradiated with ultraviolet light

International Nuclear Information System (INIS)

Meneghini, R.; Cordeiro-Stone, M.; Schumacher, R.I.

1981-01-01

Native newly synthesized DNA from human cells (xeroderma pigmentosum type) irradiated with ultraviolet light releases short pieces of DNA (L-DNA) when incubated with the single-strand specific S 1 nuclease. This is not observed in the case of unirradiated cells. Previous experiments had shown that the L-DNA resulted from the action of S 1 nuclease upon gaps, i.e., single-stranded DNA discontinuities in larger pieces of double-stranded DNA. We verified that the duplex L-DNA, that arises from the inter-gap regions upon S 1 nuclease treatment, has a size which approximates the distance between two pyrimidine dimers on the same strand. A method was devised to measure the size of the gaps. These parameters have been considered in the proposition of a model for DNA synthesis on a template containing pyrimidine dimers

Although both nurse empowerment and competence are fundamental concepts of describing newly graduated nurses' professional development and job satisfaction, only few studies exist on the relationship between these concepts. Therefore, the purpose of this study was to determine how newly graduated nurses assess their empowerment and to clarify professional competence compared to other work-related factors. A descriptive, cross-sectional and correlational design was applied. The sample comprised newly graduated nurses (n = 318) in Finland. Empowerment was measured using the 19-item Qualities of an Empowered Nurse scale and the Nurse Competence Scale measured nurses' self-assessed generic competence. In addition to demographic data, the background data included employment sector (public/private), job satisfaction, intent to change/leave job, work schedule (shifts/business hours) and assessments of the quality of care in the workplace. The data were analysed statistically by using Spearman's correlation coefficient as well as the One-Way and Multivariate Analysis of Variance. Cronbach's alpha coefficient was used to estimate the internal consistency. Newly graduated nurses perceived their level of empowerment and competence fairly high. The association between nurse empowerment and professional competence was statistically significant. Other variables correlating positively to empowerment included employment sector, age, job satisfaction, intent to change job, work schedule, and satisfaction with the quality of care in the work unit. The study indicates competence had the strongest effect on newly graduated nurses' empowerment. New graduates need support and career opportunities. In the future, nurses' further education and nurse managers' resources for supporting and empowering nurses should respond to the newly graduated nurses' requisites for attractive and meaningful work.

Zhao, Kun; Lee, Calvin; Anda, Jaime; Wong, Gerard

2015-03-01

For monotrichous bacteria, Pseudomonas aeruginosa, after cell division, one daughter cell inherits the old flagellum from its mother cell, and the other grows a new flagellum during or after cell division. It had been shown that the new flagellum grows at the distal pole of the dividing cell when the two daughter cells haven't completely separated. However, for those daughter cells who grow new flagella after division, it still remains unknown at which pole the new flagellum will grow. Here, by combining our newly developed bacteria family tree tracking techniques with genetic manipulation method, we showed that for the daughter cell who did not inherit the old flagellum, a new flagellum has about 90% chances to grow at the newly formed pole. We proposed a model for flagellation of P. aeruginosa.

Full Text Available The clinical competence of newly registered nurses relating to the care of individual Clients, depends on their ability to correlate theoretical knowledge learned in the classroom with practice and the development of clinical skills. Its foundation lies in the ability to identify and solve problems that emanate from critical thinking, analytical reasoning and reflective practice. It is clear that the quality of clinical exposure plays a leading role in the development of nursing professionals. Nursing skills alone cannot ensure quality care of clients without the application of theory. Facilitation of this theory to practice therefore remains an essential component of nursing education. This study was aimed at identifying areas of incompetence of newly registered nurses (1998- 2001 in the clinical area by determining the newly registered nurses1 and professional nurses1 perceptions of the competence of the newly registered nurses. A quantitative, non-experimental, descriptive survey was used to collect the data regarding the clinical competence of newly registered nurses (1998-2001.

Progesterone (P) is an important hormone for the establishment of pregnancy, and its administration is useful for luteal insufficiency. Considering the problems of commercially available oral and injection drugs, hospital-formulated vaginal suppositories are clinically used. However, since the half-life of P suppositories is short, it is difficult to maintain its constant blood concentration. To sustain drug efficacy and prevent side-effects, we are attempting to develop sustained-release suppositories by examining the degree of sustained-release of active ingredients. In this study, we examined the combinations of granulation methods and release systems for the preparation of sustained-release granules of P, and produced 13 types of sustained-release granules. We also examined the diameter, content, and dissolution of each type of granules, and confirmed that the sustained-release of all types of granules was satisfactory. Among the sustained-release granules, we selected granules with a content and a degree of sustained-release suitable for sustained-release suppositories.
'Practising under your own Pin'- a description of the transition experiences of newly qualified midwives.

Transition experiences of newly qualified midwives were examined in depth during the third phase of a UK evaluation study of midwifery education. The fitness to practise and the retention of newly qualified nursing and midwifery graduates are pressing concerns for health care managers. The advantages of preceptorship are reported in the literature but the content and timing of schemes remain unclear. A semi-structured diary was kept for up to 6 months by 35 newly qualified midwives in 18 work sites covering all countries in the UK. The preceptor and supervisor of midwives for each newly qualified midwife completed short questionnaires about their preceptee's performance, and a further sub-sample of newly qualified midwives and preceptors participated in a semi-structured interview. Data were analysed to elicit aspects of newly qualified midwives transition experiences. Findings confirm that structured preceptorship schemes are not widely available. Newly qualified midwives primarily obtained transition support from members of the midwifery team. Although perceived as competent, there is no demarcation point in becoming confident to practise as a registered practitioner. Implications for managers include the importance of a supportive culture within clinical teams for successful transition and the introduction of structured preceptorship schemes facilitated by appropriate rotation patterns. © 2012 John Wiley & Sons Ltd.

Based on the potential beneficial effects of growth hormone releasing peptide (GHRP)-6 on muscle functions, a newly synthesized GHRP-6-biotin conjugate was tested on cultured myoblast cells. Increased expression of myogenic marker proteins was observed in GHRP-6-biotin conjugate-treated cells. Additionally, increased expression levels of insulin-like growth factor-1 and collagen type I were observed. Furthermore, GHRP-6-biotin conjugate-treated cells showed increased metabolic activity, as indicated by increased concentrations of energy metabolites, such as ATP and lactate, and increased enzymatic activity of lactate dehydrogenase and creatine kinase. Finally, binding protein analysis suggested few candidate proteins, including desmin, actin, and zinc finger protein 691 as potential targets for GHRP6-biotin conjugate action. These results suggest that the newly synthesized GHRP-6-biotin conjugate has myogenic stimulating activity through, at least in part, by stimulating collagen type I synthesis and several key proteins. Practical applications of the GHRP-6-biotin conjugate could include improving muscle condition.
Insights from the complete chloroplast genome into the evolution of Sesamum indicum L.

Full Text Available Sesame (Sesamum indicum L. is one of the oldest oilseed crops. In order to investigate the evolutionary characters according to the Sesame Genome Project, apart from sequencing its nuclear genome, we sequenced the complete chloroplast genome of S. indicum cv. Yuzhi 11 (white seeded using Illumina and 454 sequencing. Comparisons of chloroplast genomes between S. indicum and the 18 other higher plants were then analyzed. The chloroplast genome of cv. Yuzhi 11 contains 153,338 bp and a total of 114 unique genes (KC569603. The number of chloroplast genes in sesame is the same as that in Nicotiana tabacum, Vitis vinifera and Platanus occidentalis. The variation in the length of the large single-copy (LSC regions and inverted repeats (IR in sesame compared to 18 other higher plant species was the main contributor to size variation in the cp genome in these species. The 77 functional chloroplast genes, except for ycf1 and ycf2, were highly conserved. The deletion of the cp ycf1 gene sequence in cp genomes may be due either to its transfer to the nuclear genome, as has occurred in sesame, or direct deletion, as has occurred in Panax ginseng and Cucumis sativus. The sesame ycf2 gene is only 5,721 bp in length and has lost about 1,179 bp. Nucleotides 1-585 of ycf2 when queried in BLAST had hits in the sesame draft genome. Five repeats (R10, R12, R13, R14 and R17 were unique to the sesame chloroplast genome. We also found that IR contraction/expansion in the cp genome alters its rate of evolution. Chloroplast genes and repeats display the signature of convergent evolution in sesame and other species. These findings provide a foundation for further investigation of cp genome evolution in Sesamum and other higher plants.

Serum concentrations of total cholesterol, LDL-C, HDL-C, triglycerides, apoA and apoB, SGOT, SGPT, glucose and insulin were measured at the end of supplementation period in all studied groups. Hypercholesterolemic feeding resulted in a significant elevation of TC, TG, LDL-C, HDL-C, SGOT and SGPT as compared to the normocholesterolemic diet group (P0.05. In contrast, rabbits supplemented with sesame oil were found to have lower circulating concentrations of TC, LDL-C, HDL-C, SGOT and SGPT (P0.05. Supplementation with sesame oil, but not sesame seed, can ameliorate serum levels of lipids and hepatic enzymes in rabbits under a high-fat diet.

This week, I’d like to focus on respect, whether at home, at work or on the international scene. Last week, I had the opportunity to visit the SESAME laboratory in Jordan along with the new European Commissioner for Research, Carlos Moedas. Since taking up his post, Mr Moedas has attached great importance to the role science can play in diplomacy, and the visit was on his initiative. Through the EU-funded CESSAMag project, CERN is coordinating the provision of magnets and power supplies for the SESAME main ring. The first are currently being tested at CERN by a team involving accelerator scientists from the SESAME members, and all are due to be delivered to SESAME in time for commissioning in the second half of 2016. SESAME, and CERN’s contribution to the project, are well documented in the pages of the Bulletin, but what really impresses when you visit the lab is the diversity of people working there and the degree of mutual respect they show to each other.

Mentorship is an increasingly popular innovation from business and industry that is being applied in health-care contexts. This paper explores the concept of mentorship for newly appointed physicians in their first substantive senior post, and specifically its utilization to enhance patient safety. Semi-structured face to face and telephone interviews with Medical Directors (n = 5), Deputy Medical Directors (n = 4), and Clinical Directors (n = 6) from 9 acute NHS Trusts in the Yorkshire and Humber region in the north of England. A focused thematic analysis was used. A number of beneficial outcomes were associated with mentorship for newly appointed physicians including greater personal and professional support, organizational commitment, and general well-being. Providing newly appointed senior physicians with support through mentorship was considered to enhance the safety of patient care. Mentorship may prevent or reduce active failures, be used to identify threats in the local working environment, and in the longer term, address latent threats to safety within the organization by encouraging a healthier safety culture. Offering mentorship to all newly appointed physicians in their first substantive post in health care may be a useful strategy to support the development of their clinical, professional, and personal skills in this transitional period that may also enhance the safety of patient care.

Full Text Available Abstract Background The incidence of primary osteoporosis is higher in Japan than in USA and European countries. Recently, the importance of preventive medicine has been gradually recognized in the field of orthopaedic surgery with a concept that peak bone mass should be increased in childhood as much as possible for the prevention of osteoporosis. Under such background, we have developed a new bean snack with an aim to improve bone volume loss. In this study, we examined the effects of a newly developed snack on bone volume and density in osteoporosis model mice. Methods Orchiectomy (ORX and ovariectomy (OVX were performed for C57BL/6J mice of twelve-week-old (Jackson Laboratory, Bar Harbar, ME, USA were used in this experiment. We prepared and given three types of powder diet e.g.: normal calcium diet (NCD, Ca: 0.9%, Clea Japan Co., Tokyo, Japan, low calcium diet (LCD, Ca: 0.63%, Clea Japan Co., and special diet (SCD, Ca: 0.9%. Eighteen weeks after surgery, all the animals were sacrified and prepared for histomorphometric analysis to quantify bone density and bone mineral content. Results As a result of histomorphometric examination, SCD was revealed to enhance bone volume irrespective of age and sex. The bone density was increased significantly in osteoporosis model mice fed the newly developmental snack as compared with the control mice. The bone mineral content was also enhanced significantly. These phenomena were revealed in both sexes. Conclusion It is shown that the newly developed bean snack is highly effective for the improvement of bone volume loss irrespective of sex. We demonstrated that newly developmental snack supplements may be a useful preventive measure for Japanese whose bone mineral density values are less than the ideal condition.

wangensteen s., johansson i.s., björkström m.e. & nordström g. (2010) Critical thinking dispositions among newly graduated nurses. Journal of Advanced Nursing66(10), 2170–2181. Aim The aim of the study was to describe critical thinking dispositions among newly graduated nurses in Norway, and to study whether background data had any impact on critical thinking dispositions. Background Competence in critical thinking is one of the expectations of nursing education. Critical thinkers are described as well-informed, inquisitive, open-minded and orderly in complex matters. Critical thinking competence has thus been designated as an outcome for judging the quality of nursing education programmes and for the development of clinical judgement. The ability to think critically is also described as reducing the research–practice gap and fostering evidence-based nursing. Methods A cross-sectional descriptive study was performed. The data were collected between October 2006 and April 2007 using the California Critical Thinking Disposition Inventory. The response rate was 33% (n= 618). Pearson’s chi-square tests were used to analyse the data. Results Nearly 80% of the respondents reported a positive disposition towards critical thinking. The highest mean score was on the Inquisitiveness subscale and the lowest on the Truth-seeking subscale. A statistically significant higher proportion of nurses with high critical thinking scores were found among those older than 30 years, those with university education prior to nursing education, and those working in community health care. Conclusion Nurse leaders and nurse teachers should encourage and nurture critical thinking among newly graduated nurses and nursing students. The low Truth-seeking scores found may be a result of traditional teaching strategies in nursing education and might indicate a need for more student-active learning models. PMID:20384637
One- and two-dimensional search of an equation of state using a newly released 2DRoptimize package

Jamal, M.; Reshak, A. H.

2018-05-01

A new package called 2DRoptimize has been released for performing two-dimensional searches of the equation of state (EOS) for rhombohedral, tetragonal, and hexagonal compounds. The package is compatible and available with the WIEN2k package. The 2DRoptimize package performs a convenient volume and c/a structure optimization. First, the package finds the best value for c/a and the associated energy for each volume. In the second step, it calculates the EoS. The package then finds the equation of the c/a ratio vs. volume to calculate the c/a ratio at the optimized volume. In the last stage, by using the optimized volume and c/a ratio, the 2DRoptimize package calculates a and c lattice constants for tetragonal and hexagonal compounds, as well as the a lattice constant with the α angle for rhombohedral compounds. We tested our new package based on several hexagonal, tetragonal, and rhombohedral structures, and the 2D search results for the EOS showed that this method is more accurate than 1D search. Our results agreed very well with the experimental data and they were better than previous theoretical calculations.

The number of migrants and refugees in Europe in the past few years has increased dramatically due to war, violence or prosecutions in their homeland. Migration may affect physical, mental and social health. The objective of this article is to assess migrants and refugees' health problems, and to recommend appropriate interventions. A PubMed search of published articles on health problems of newly arrived migrants and refugees was conducted from 2003 through 2016, focusing on the current refugee crisis in Europe. In addition to communicable diseases, such as respiratory, gastrointestinal and dermatologic infections, non-communicable diseases, including chronic conditions, mental and social problems, account for a significant morbidity burden in newly arrived migrants and refugees. Vaccine-preventable diseases are also of outmost importance. The appropriate management of newly arrived refugees and migrants' health problems is affected by barriers to access to health care including legal, communication, cultural and bureaucratic difficulties. There is diversity and lack of integration regarding health care provision across Europe due to policy differences between health care systems and social services. There is a notable burden of communicable and non-communicable diseases among newly arrived migrants and refugees. Provision of health care at reception and temporary centres should be integrated and provided by a multidisciplinary team Appropriate health care of migrants and refugees could greatly enhance their health and social status which will benefit also the host countries at large. © International Society of Travel Medicine, 2017.

This study was conducted to investigate the effects of HPMC (K4M and K100M) as well as tragacanth on the drug release rate of diltiazem (DLTZ) from matrix tablets prepared by direct compression method.Mechanism of drug transport through the matrices was studied by fitting the release data to the 10 kinetic models. 3 model independent parameters; i. e., mean dissolution time (MDT), mean release rate (MRR) and release rate efficacy (RE) as well as 5 time point approaches were established to compare the dissolution profiles. To find correlation between fraction of drug released and polymer's molecular weight, dissolution data were fitted into two proposed equations.All polymers could sustain drug release up to 10 h. The release data were fitted best to Peppas and Higuchi square root kinetic models considering squared correlation coefficient and mean percent error (MPE). RE and MRR were decreased when polymer to drug ratio was increased. Conversely, t60% was increased with raising polymer /drug ratio. The fractions of drug released from the formulations prepared with tragacanth were more than those formulated using the same amount of HPMC K4M and HPMC K100M.Preparation of DLTZ matrices applying HPMCK4M, HPMC K100M and tragacanth could effectively extend the drug release. © Georg Thieme Verlag KG Stuttgart · New York.
Accelerated in-vitro release testing methods for extended-release parenteral dosage forms.

2012-07-01

This review highlights current methods and strategies for accelerated in-vitro drug release testing of extended-release parenteral dosage forms such as polymeric microparticulate systems, lipid microparticulate systems, in-situ depot-forming systems and implants. Extended-release parenteral dosage forms are typically designed to maintain the effective drug concentration over periods of weeks, months or even years. Consequently, 'real-time' in-vitro release tests for these dosage forms are often run over a long time period. Accelerated in-vitro release methods can provide rapid evaluation and therefore are desirable for quality control purposes. To this end, different accelerated in-vitro release methods using United States Pharmacopeia (USP) apparatus have been developed. Different mechanisms of accelerating drug release from extended-release parenteral dosage forms, along with the accelerated in-vitro release testing methods currently employed are discussed. Accelerated in-vitro release testing methods with good discriminatory ability are critical for quality control of extended-release parenteral products. Methods that can be used in the development of in-vitro-in-vivo correlation (IVIVC) are desirable; however, for complex parenteral products this may not always be achievable. © 2012 The Authors.

Conclusions Accelerated in vitro release testing methods with good discriminatory ability are critical for quality control of extended release parenteral products. Methods that can be used in the development of in vitro-in vivo correlation (IVIVC) are desirable, however for complex parenteral products this may not always be achievable. PMID:22686344
Ultra Structural Characterisation of Tetherin - a Protein Capable of Preventing Viral Release from the Plasma Membrane

Full Text Available Tetherin is an antiviral restriction factor made by mammalian cells to protect them from viral infection. It prevents newly formed virus particles from leaving infected cells. Its antiviral mechanism appears to be remarkably uncomplicated. In 2 studies published in PLoS Pathogens electron microscopy is used to support the hypothesis that the tethers that link HIV-1 virions to tetherin expressing cells contain tetherin and are likely to contain tetherin alone. They also show that the HIV-1 encoded tetherin antagonist that is known to cause tetherin degradation, Vpu, serves to reduce the amount of tetherin in the particles thereby allowing their release.

The effect of sesame oil (SSO) and sunflower oil (SFO) (the excipients) on the plasma disposition of ivermectin (IVM) following intravenous (i.v.) and subcutaneous (s.c.) administration at a dosage of 200 microg/kg was investigated in goats. Ten clinically healthy crossbred goats were used in the study. The animals were allocated by weight and sex into two groups of five animals each. Group 1 (n = 5) received the drug and excipient by the i.v. route only and group 2 received drug and excipient by the s.c. route only. The study was designed according to a two-phase crossover design protocol. In the first phase three animals in group 1 were i.v. administered IVM (0.2 mg/kg) + SSO (1 mL) and the other two animals received IVM (0.2 mg/kg) + SFO (1 mL). In the second phase animals were crossed over and received the alternate excipient with IVM at the same dosages. In group 2 during the first phase, three animals were s.c. administered IVM (0.2 mg/kg) + SSO (1 mL) and the other two animals were received IVM (0.2 mg/kg) + SFO (1 mL). In the second phase animals were crossed over and received the alternate excipient with IVM at the same dosages. A 4-week washout period was allowed between the two phases. In group 2 significantly increased dermal thickness was observed at the s.c. injection site of the all animals which received IVM during phase I regardless of the excipient. There was almost no change observed at the injection site of any animal during the second phase of the study following s.c. administration. In group 2 the plasma concentrations of IVM in the second phase for both excipient combinations were much higher than the plasma concentrations following first administration and appeared to be related with the dermal changes. The mean plasma disposition of IVM in combination with SSO or SFO was similar following i.v. administration. Longer terminal elimination half-lives and resultant longer mean resident time were observed after s.c. administration of the both

Ten patients with newly diagnosed, advanced prostatic cancer were treated with radiotherapy and hormone therapy to improve tumor control and survival. Eight patients with hormonally relapsed prostatic cancer were treated with radiotherapy to improve their quality of life. Local control of the tumor was achieved in 9 of 10 patients with newly diagnosed, advanced prostatic cancer. Five of eight patients with hormonally relapsed prostatic cancer obtained improved quality of life. Combined radiotherapy and hormone therapy were effective in the treatment of newly diagnosed, advanced prostatic cancer, and radiotherapy was useful for improving the quality of life of patients with hormonally relapsed prostatic cancer.

Competitive release and facilitation of drug-resistant parasites after therapeutic chemotherapy in a rodent malaria model

Malaria infections frequently consist of mixtures of drug-resistant and drug-sensitive parasites. If crowding occurs, where clonal population densities are suppressed by the presence of coinfecting clones, removal of susceptible clones by drug treatment could allow resistant clones to expand into the newly vacated niche space within a host. Theoretical models show that, if such competitive release occurs, it can be a potent contributor to the strength of selection, greatly accelerating the rate at which resistance spreads in a population. A variety of correlational field data suggest that competitive release could occur in human malaria populations, but direct evidence cannot be ethically obtained from human infections. Here we show competitive release after pyrimethamine curative chemotherapy of acute infections of the rodent malaria Plasmodium chabaudi in laboratory mice. The expansion of resistant parasite numbers after treatment resulted in enhanced transmission-stage densities. After the elimination or near-elimination of sensitive parasites, the number of resistant parasites increased beyond that achieved when a competitor had never been present. Thus, a substantial competitive release occurred, markedly elevating the fitness advantages of drug resistance above those arising from survival alone. This finding may explain the rapid spread of drug resistance and the subsequently brief useful lifespans of some antimalarial drugs. In a second experiment, where subcurative chemotherapy was administered, the resistant clone was only partly released from competitive suppression and experienced a restriction in the size of its expansion after treatment. This finding raises the prospect of harnessing in-host ecology to slow the spread of drug resistance. ?? 2007 by The National Academy of Sciences of the USA.

The Emerging Oilseed Crop Sesamum indicum Enters the “Omics” Era

Full Text Available Sesame (Sesamum indicum L. is one of the oldest oilseed crops widely grown in Africa and Asia for its high-quality nutritional seeds. It is well adapted to harsh environments and constitutes an alternative cash crop for smallholders in developing countries. Despite its economic and nutritional importance, sesame is considered as an orphan crop because it has received very little attention from science. As a consequence, it lags behind the other major oil crops as far as genetic improvement is concerned. In recent years, the scenario has considerably changed with the decoding of the sesame nuclear genome leading to the development of various genomic resources including molecular markers, comprehensive genetic maps, high-quality transcriptome assemblies, web-based functional databases and diverse daft genome sequences. The availability of these tools in association with the discovery of candidate genes and quantitative trait locis for key agronomic traits including high oil content and quality, waterlogging and drought tolerance, disease resistance, cytoplasmic male sterility, high yield, pave the way to the development of some new strategies for sesame genetic improvement. As a result, sesame has graduated from an “orphan crop” to a “genomic resource-rich crop.” With the limited research teams working on sesame worldwide, more synergic efforts are needed to integrate these resources in sesame breeding for productivity upsurge, ensuring food security and improved livelihood in developing countries. This review retraces the evolution of sesame research by highlighting the recent advances in the “Omics” area and also critically discusses the future prospects for a further genetic improvement and a better expansion of this crop.

Full Text Available Introduction Crop density enhancement is a method to increase yield per unit area. The spatial distribution of plants is related to radiation absorption. Therefore, it could play an effective role in photosynthesis and yield, since Crop Growth Rate (CGR is a function of used radiation energy in photosynthesis. Totally, increasing radiation absorption efficiency and yield need sufficient leaf area and suitable distribution of leaves in canopy. Ahmad et al., (2002 planted sesame with different inter row- spacing (30, 45 and 60 cm, they reported that the maximum plant height and economic yield were obtained from inter row- spacing of 45 cm. Rahnama and Bakhshandeh (2006 planted sesame with different inter row- spacing (37.5, 50 and 60 cm and the results showed that the number of capsules per plant, seed weight as well as seed oil per plant, increased with increasing inter row- spacing. Karasan et al., (2007 reported that decreasing inter row- spacing resulted in seed yield enhancement and reduction in number of capsules per plant. Material and Methods An experiment using split-plot based on randomized complete blocks design was performed. The experiment was carried with three replications in two years (2012 and 2013 at the agricultural research station of Ferdowsi University of Mashhad. For this purpose, the main plot was the density per square meter with three levels (30, 40 and 50 plants per square meter and the sub main plot was planting pattern (rectangle, square and rhombic. The size of each plot was 2×3 meters. The distance between plots and blocks were 0.5 and 1 meter, respectively. Intra row- spacing for rectangle planting pattern for densities of 30, 40 and 50 plants per square meter was 6, 5 and 4 cm, respectively. In square and rhombic planting patterns, 2 lines was planted in each row and inter row- spacing for densities of 30, 40 and 50 plants per square meter were 18, 16 and 14 cm. economic yield measured at the end of growth season

Cytochrome P450 cam (a camphor hydroxylase) from the soil bacterium Pseudomonas putida shows potential importance in environmental applications such as the degradation of chlorinated organic pollutants. Seven P450 cam mutants generated from Sequence Saturation Mutagenesis (SeSaM) and isolated by selection on minimal media with either 3-chloroindole or the insecticide endosulfan were studied for their ability to oxidize of 3-chloroindole to isatin. The wild-type enzyme did not accept 3-chloroindole as a substrate. Mutant (E156G/V247F/V253G/F256S) had the highest maximal velocity in the conversion of 3-chloroindole to isatin, whereas mutants (T56A/N116H/D297N) and (G60S/Y75H) had highest k cat /K M values. Six of the mutants had more than one mutation, and within this set, mutation of residues 297 and 179 was observed twice. Docking simulations were performed on models of the mutant enzymes; the wild-type did not accommodate 3-chloroindole in the active site, whereas all the mutants did. We propose two potential reaction pathways for dechlorination of 3-chloroindole.

The purpose of this review is to evaluate the final forms that have been proposed for radioactive-containing solid wastes and to determine their application to the solid wastes that will result from the treatment of newly generated liquid low-level waste (NGLLLW) and Melton Valley Storage Tank (MVST) supernate at the Oak Ridge National Laboratory (ORNL). Since cesium and strontium are the predominant radionuclides in NGLLLW and MVST supernate, this review is focused on the stabilization and solidification of solid wastes containing these radionuclides in cement, glass, and polymeric materials-the principal waste forms that have been tested with these types of wastes. Several studies have shown that both cesium and strontium are leached by distilled water from solidified cement, although the leachabilities of cesium are generally higher than those of strontium under similar conditions. The situation is exacerbated by the presence of sulfates in the solution, as manifested by cracking of the grout. Additives such as bentonite, blast-furnace slag, fly ash, montmorillonite, pottery clay, silica, and zeolites generally decrease the cesium and strontium release rates. Longer cement curing times (>28 d) and high ionic strengths of the leachates, such as those that occur in seawater, also decrease the leach rates of these radionuclides. Lower cesium leach rates are observed from vitrified wastes than from grout waste forms. However, significant quantities of cesium are volatilized due to the elevated temperatures required to vitrify the waste. Hence, vitrification will generally require the use of cleanup systems for the off-gases to prevent their release into the atmosphere

Ozone causes vagally mediated airway hyperreactivity and recruits inflammatory cells, including eosinophils, to lungs, where they mediate ozone-induced hyperreactivity 1 day after exposure but are paradoxically protective 3 days later. We aimed to test the role of newly divided eosinophils in ozone-induced airway hyperreactivity in sensitized and nonsensitized guinea pigs. Nonsensitized and sensitized guinea pigs were treated with 5-bromo-2-deoxyuridine (BrdU) to label newly divided cells and were exposed to air or ozone for 4 h. Later (1 or 3 days later), vagally induced bronchoconstriction was measured, and inflammatory cells were harvested from bone marrow, blood, and bronchoalveolar lavage. Ozone induced eosinophil hematopoiesis. One day after ozone, mature eosinophils dominate the inflammatory response and potentiate vagally induced bronchoconstriction. However, by 3 days, newly divided eosinophils have reached the lungs, where they inhibit ozone-induced airway hyperreactivity because depleting them with antibody to IL-5 or a TNF-α antagonist worsened vagally induced bronchoconstriction. In sensitized guinea pigs, both ozone-induced eosinophil hematopoiesis and subsequent recruitment of newly divided eosinophils to lungs 3 days later failed to occur. Thus mature eosinophils dominated the ozone-induced inflammatory response in sensitized guinea pigs. Depleting these mature eosinophils prevented ozone-induced airway hyperreactivity in sensitized animals. Ozone induces eosinophil hematopoiesis and recruitment to lungs, where 3 days later, newly divided eosinophils attenuate vagally mediated hyperreactivity. Ozone-induced hematopoiesis of beneficial eosinophils is blocked by a TNF-α antagonist or by prior sensitization. In these animals, mature eosinophils are associated with hyperreactivity. Thus interventions targeting eosinophils, although beneficial in atopic individuals, may delay resolution of airway hyperreactivity in nonatopic individuals. Copyright �

Many people with epilepsy report experiencing psychological difficulties such as anxiety, depression and neuropsychological deficits including memory problems. Research has shown that these difficulties are often present not only for people with chronic epilepsy but also for people with newly diagnosed epilepsy. Despite this, there are very few published interventions that detail means to help people with newly diagnosed epilepsy manage these problems. To identify and assess possible psychological and neuropsychological interventions for adults with newly diagnosed epilepsy. We searched the following databases on 30 June 2015: the Cochrane Epilepsy Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), SCOPUS, PsycINFO, CINAHL, ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). This review includes all randomised controlled trials, quasi-randomised controlled trials, prospective cohort controlled studies, and prospective before and after studies which include psychological or neuropsychological interventions for people with newly diagnosed epilepsy. We excluded studies that included people with epilepsy and any other psychological disorder or neurological condition. We excluded studies carried out which recruited only children. We used the standard methodological procedure expected by The Cochrane Collaboration. Two authors independently completed data extraction and risk of bias analysis. The results of this were cross-checked and third author resolved any discrepancies. In the event of missing data, we contacted the study authors. Meta-analysis was not completed due to differences in the intervention and outcomes reported in the two studies. We included two randomised controlled trials assessing psychological interventions for people with newly diagnosed epilepsy. One study assessed a cognitive behavioural intervention (CBI) in an adolescent

Patients newly diagnosed with cancer are often confronted with feelings of uncertainty and life threat. A significant proportion may report impairments in psychosocial well-being. Previous studies examining protective psychological factors such as hope and emotion regulation (ER) have yet to investigate these processes concurrently within a common self-regulation framework and/or focus on newly diagnosed patients. The present study aimed to examine how hope and ER may relate to psychosocial outcomes of patients newly diagnosed with cancer. The present study used a cross-sectional design with self-report questionnaires. Participants were newly diagnosed patients (N = 101) recruited from three cancer therapy clinics in a hospital. Patients completed measures of hope, ER (cognitive reappraisal and expressive suppression), and psychosocial well-being (life satisfaction and negative affectivity). Findings showed that (1) hope and reappraisal, but not suppression, were associated with well-being and (2) the interaction between hope and reappraisal was associated with well-being; reappraisal was not associated with well-being in high hope patients, while high reappraisal was associated with better well-being in low hope patients. Individual differences in hope and reappraisal appeared to be associated with psychosocial outcomes in newly diagnosed cancer patients. Hopeful thinking appeared to benefit patients' psychosocial well-being. In addition, an interaction effect between hope and reappraisal suggested that reappraisal as an ER strategy may be particularly adaptive for patients with low hope.

Extracellular high potassium inhibits renin release in vitro by increasing calcium concentrations in the juxtaglomerular cells. The authors found that the decreased response of renin release from rat kidney cortical slices in high potassium solution changed to a strikingly increased one in the presence of nifedipine at doses over 10{sup {minus}6} M. They then examined the stimulatory effect of extracellular high potassium in the presence of nifedipine on renin release. The enhancement of release was significantly suppressed either by propranolol or by metoprolol but not by prazosin. High potassium plus nifedipine-induced increase in renin release was markedly attenuated by renal denervation. The enhancing effect was not observed when the slices were incubated in calcium-free medium. Divalent cations such as Cd{sup 2+}, Co{sup 2+}, and Mn{sup 2+} blocked this enhancement in a concentration-dependent manner. High potassium elicited an increase in {sup 3}H efflux from the slices preloaded with ({sup 3}H)-norepinephrine. The increasing effect was not influenced by nifedipine but was abolished by the removal of extracellular calcium or by the addition of divalent cations. These observations suggest to us that the high potassium plus nifedipine-induced increase in renin release from the slices is mediated by norepinephrine derived from renal sympathetic nerves and that this neuronally released norepinephrine stimulates renin release via activation of {beta}-adrenoceptors.

The laser-induced release of a well-known hepatoprotective drug (silibinin, SLB) from a temperature-sensitive polymeric composite loaded with silver nanoparticles (Ag NPs) was investigated. The surface chemistry tuning and the specific design of Ag NPs are fundamental in view of the engineering of specific stimuli-responsive systems, able to control drug release in response to external stimuli. The release profiles of SLB from the newly synthesized PEG–PLA@Ag composite show strong dependences on laser wavelength and Ag NPs’ Surface Plasmon Resonance (SPR). The resonant laser light excites the SPR of the NPs and the absorbed energy is converted into heat due to electron–photon collisions. The heat generated from the nanometer-sized metal particles embedded within the polymer is efficient and strongly localized. The nanovector, irradiated by a relatively low-intensity laser but tuned specifically to the metal NPs’ SPR, releases the encapsulated drug with a higher efficiency than that not irradiated or irradiated with a laser wavelength far from the metal SPR. A combination of analytical techniques including UV–Vis, NMR, and FT-IR spectroscopy and scanning/transmission electron microscopy has been used to study the structural and morphological properties of the composite. The controllable specificity of this approach and the possibility of the SPR-mediated localized photothermal effect to be usefully applied in aqueous environments are the relevant advances of the proposed system for photothermal therapies that make use of visible optical radiation or for the drug delivery in proximity of the tumor cells.

Midwifery has developed its own philosophy to formalise its unique identity as a profession. Newly-graduated midwives are taught, and ideally embrace, this philosophy during their education. However, embarking in their career within a predominantly institutionalised and the medically focused health-care model may challenge this application. The research question guiding this study was as follows: 'How do newly graduated midwives deal with applying the philosophy of midwifery in their first six months of practice?' The aim was to generate a grounded theory around this social process. This Western Australian grounded theory study is conceptualised within the social theory of symbolic interactionism. Data were collected by means of in-depth, semi-structured interviews with 11 recent midwifery graduates. Participant and interviewer's journals provided supplementary data. The 'constant comparison' approach was used for data analysis. The substantive theory of transcending barriers was generated. Three stages in transcending barriers were identified: Addressing personal attributes, Understanding the 'bigger picture', and finally, 'Evaluating, planning and acting' to provide woman-centred care. An overview of these three stages provides the focus of this article. The theory of transcending barriers provides a new perspective on how newly-graduated midwives deal with applying the philosophy of midwifery in their first six months of practice. A number of implications for pre and post registration midwifery education and policy development are suggested, as well as recommendations for future research. Copyright © 2013 Elsevier Ltd.

Full Text Available Introduction Sesame (Sesamun indicum L. is an important oil seed crop. Its seed has excellent nutritional value with a high and unique protein composition, making it a perfect food. Salinity is a serious problem in many regions of the world including Iran. Salinity stress is one of the widespread environmental constraints affecting crop productivity. Salinity generally induces osmotic stress and causes direct ion injury by disrupting ion homeostasis and the ion balance within plant cells (25. Seed priming is one of the ways to reduce negative effects of salt which is used for increasing germination percentage and seed resistance in salty zones. Seed priming is a pre-germination treatment that provides a moisture level sufficient to start pre-germination metabolic processes. It entails the partial germination of seeds by soaking them in water (or in a solution of salts for specified period of time, and then re-dry them just before radicle emerges (24. Priming stimulates many of the metabolic processes involved with the early phases of germination. Given that part of the germination processes have been initiated, seedlings from primed seed grow faster, grow more vigorously, and perform better in adverse conditions (24. The objective of this study was to investigate the effects of salinity stress caused by alkali salts on growth and some physiologic characteristics of sesame. Materials and Methods This study was conducted in a greenhouse in Vali-e-Asr University of Rafsanjan as factorial arrangement in randomized complete block design with three replications. Experimental factors included priming (control (unprimed, hydropriming, halopriming with NaCl and NaHCO3 and level of salinity with sodium bicarbonate salt (Zero, 15, 30 and 45 mM. Seeds were planted in pots filled with perlite and cocopite (1:1. The pots were irrigated with a nutrient solution (with half strength Hoagland's solution. After the fourth true leaves appeared, salinty stress in

Full Text Available In order to study the effects of different irrigation intervals and plant density on morphological characteristics, grain and oil yields of sesame, an experiment was conducted at experimental station, college of agriculture, Ferdowsi University of Mashhad. Four different irrigation intervals (one, two, three and four weeks with four plant densities (20, 30, 40 and 50 plants/m2 were compared in a spilt plot arrangement based on randomized complete block design with four replications. Irrigation intervals and plant densities allocated in main plots and subplots, respectively. Different characteristics such as plant height, distance of first capsule from soil surface, number of branches per plant, number of grains per capsule, number of capsules per plant, grain yield, 1000-seed weight, harvest index and oil yield were recorded. The results showed that there were no significant difference between different irrigation intervals in terms of distance of first capsule from soil surface, number of grains per capsule, 1000-seed weight and harvest index. Different irrigation intervals had significant effects on plant height, number of branches per plant, number of capsules per plant, grain yield and oil yield. There were significant differences between different plant densities in terms of distance of first capsule from soil surface, number of branches per plant, number of graines per capsule, number of capsules per plant, grain yield, harvest index and oil yield. The highest grain yield (798/7 kg/ha and oil yield (412/8 kg/ha were obtained at one week and four weeks irrigation intervals, respectively. Between all treatments, 50 plants/m2 and one week irrigation interval produced the highest grain yield (914/7 kg/ha and oil yield (478/6 kg/ha. Because of shortage of water in Mashhad condition, the results recommended that, 50 plants/m2 and two weeks irrigation interval produced rather acceptable grain yield, with less water consumption.

To map current selection and recruitment processes for newly qualified nurses and to explore the advantages and limitations of current selection and recruitment processes. The need to improve current selection and recruitment practices for newly qualified nurses is highlighted in health policy internationally. A cross-sectional, sequential-explanatory mixed-method design with 4 components: (1) Literature review of selection and recruitment of newly qualified nurses; and (2) Literature review of a public sector professions' selection and recruitment processes; (3) Survey mapping existing selection and recruitment processes for newly qualified nurses; and (4) Qualitative study about recruiters' selection and recruitment processes. Literature searches on the selection and recruitment of newly qualified candidates in teaching and nursing (2005-2013) were conducted. Cross-sectional, mixed-method data were collected from thirty-one (n = 31) individuals in health providers in London who had responsibility for the selection and recruitment of newly qualified nurses using a survey instrument. Of these providers who took part, six (n = 6) purposively selected to be interviewed qualitatively. Issues of supply and demand in the workforce, rather than selection and recruitment tools, predominated in the literature reviews. Examples of tools to measure values, attitudes and skills were found in the nursing literature. The mapping exercise found that providers used many selection and recruitment tools, some providers combined tools to streamline process and assure quality of candidates. Most providers had processes which addressed the issue of quality in the selection and recruitment of newly qualified nurses. The 'assessment centre model', which providers were adopting, allowed for multiple levels of assessment and streamlined recruitment. There is a need to validate the efficacy of the selection tools. © 2014 John Wiley & Sons Ltd.

To explore newly graduated nurses' occupational commitment and its associations with their self-assessed professional competence and other work-related factors. As a factor affecting nurse turnover, newly graduated nurses' occupational commitment and its associations with work-related factors needs exploring to retain adequate workforce. Nurses' commitment has mainly been studied as organisational commitment, but newly graduated nurses' occupational commitment and its association with work-related factors needs further studying. This study used descriptive, cross-sectional, correlation design. A convenience sample of 318 newly graduated nurses in Finland participated responding to an electronic questionnaire. Statistical software, NCSS version 9, was used in data analysis. Frequencies, percentages, ranges, means and standard deviations summarised the data. Multivariate Analyses of Variance estimated associations between occupational commitment and work-related variables. IBM SPSS Amos version 22 estimated the model fit of Occupational Commitment Scale and Nurse Competence Scale. Newly graduated nurses' occupational commitment was good, affective commitment reaching the highest mean score. There was a significant difference between the nurse groups in favour of nurses at higher competence levels in all subscales except in limited alternatives occupational commitment. Multivariate analyses revealed significant associations between subscales of commitment and competence, turnover intentions, job satisfaction, earlier professional education and work sector, competence counting only through affective dimension. The association between occupational commitment and low turnover intentions and satisfaction with nursing occupation was strong. Higher general competence indicated higher overall occupational commitment. Managers' recognition of the influence of all dimensions of occupational commitment in newly graduated nurses' professional development is important. Follow

Emotional cues can guide selective attention processes. However, emotional stimuli can both activate long-term memory representations reflecting general world knowledge and engage newly formed memory representations representing specific knowledge from the immediate past. Here, the self-completion feature of associative memory was utilized to assess the regulation of attention processes by newly-formed emotional memory. First, new memory representations were formed by presenting pictures depi...
PWR-GALE, Radioactive Gaseous Release and Liquid Release from PWR

1 - Description of program or function: The PWR-GALE (Boiling Water Reactor Gaseous and Liquid Effluents) Code is a computerized mathematical model for calculating the release of radioactive material in gaseous and liquid effluents from pressurized water reactors (PWRs). The calculations are based on data generated from operating reactors, field tests, laboratory tests, and plant-specific design considerations incorporated to reduce the quantity of radioactive materials that may be released to the environment. 2 - Method of solution: GALE calculates expected releases based on 1) standardized coolant activities derived from ANS Standards 18.1 Working Group recommendations, 2) release and transport mechanisms that result in the appearance of radioactive material in liquid and gaseous waste streams, 3) plant-specific design features used to reduce the quantities of radioactive materials ultimately released to the environs, and 4) information received on the operation of nuclear power plants. 3 - Restrictions on the complexity of the problem: The liquid release portion of GALE uses subroutines taken from the ORIGEN (CCC-217) to calculate radionuclide buildup and decay during collection, processing, and storage of liquid radwaste. Memory requirements for this part of the program are determined by the large nuclear data base accessed by these subroutines
Changes in pheromone production, release, mating behaviour and reproductive ability of the gamma-irradiated cockroach Nauphoeta cinerea (Olivier)

Mature males of Nauphoeta cinerea produce a sex pheromone 'seducin' which has short-range effects in attracting mature females of the same species. Exposure of newly-emerged adult males to 3.5, 7, 14 or 21 krad of gamma-radiation decreased their life expectancy and affected their mating behaviour. Bioassay of dichloromethane extracts of males showed that radiation doses (14 krad) sufficient to induce sterility did not affect the ability to produce pheromone but significantly reduced the release of pheromone by inhibiting wing-raising. The sterile-male technique using males sterilized by ionizing radiation in air may not be the method of choice for control of Nauphoeta cinerea. (author)

Malnutrition is common among patients with cancer, but little attention is given to its risks and consequences. The aim of this study is to assess the nutritional status and identify the factors associated with malnutrition among newly diagnosed patients with cancer. Patients admitted with newly diagnosed cancer at a teaching hospital in Malaysia were recruited from January to April 2015. Nutritional status was assessed before treatment initiation, and patients were classified into three categories. A total of 132 pretreatment patients were recruited into the study. About half were severely malnourished. Patients with stage III cancer had the highest prevalence of severe malnourishment. Clinical parameters and disease characteristics were significantly associated with nutritional status. Demographic variables were also statistically significantly associated with severe nutritional status.

Werkenthin, Moritz; Kluge, Björn; Wessolek, Gerd

2016-12-01

Newly constructed embankments should provide both a specific bearing capacity to enable trafficability in emergency cases and a sufficient pollutant retention capacity to protect the groundwater. A number of lysimeters were installed along the A115 highway to determine total and dissolved metal concentrations in road runoff and in the soil solution of newly constructed embankments. Dissolved concentrations in soil solution of the embankments did not exceed the trigger values of the German legislation. Depending on the metal, total concentrations in soil solution were more than twice as high as dissolved concentrations. The high infiltration rates lead to increased groundwater recharge beneath the embankments (up to 4100 mm a -1 ). Although metal concentrations were not problematic from the legislators' point of view, the elevated infiltration rates beside the road facilitated the transfer of high metal loads into deeper soil layers and potentially into the groundwater as well.

The resulting nanocomposite was composed of the organic moiety, levodopa, sandwiched between Zn/Al-LDH inorganic interlayers. The basal spacing of the resulting nanocomposite was 10.9 Å. The estimated loading of levodopa in the nanocomposite was approximately 16% (w/w. A Fourier transform infrared study showed that the absorption bands of the nanocomposite were characteristic of both levodopa and Zn/Al-LDH, which further confirmed intercalation, and that the intercalated organic moiety in the nanocomposite was more thermally stable than free levodopa. The resulting nanocomposite showed sustained-release properties, so can be used in a controlled-release formulation. Cytotoxicity analysis using an MTT assay also showed increased cell viability of 3T3 cells exposed to the newly synthesized nanocomposite compared with those exposed to pure levodopa after 72 hours of exposure.Keywords: levodopa, layered double hydroxides, coprecipitation, sustained release

An analysis methodology for the hot leg break mass and energy release is developed. For the blowdown period a modified CEFLASH-4A analysis is suggested. For the post-blowdown period a new computer model named COMET is developed. Differently from previous post-blowdown analysis model FLOOD3, COMET is capable of analyzing both cold leg and hot leg break cases. The cold leg break model is essentially same as that of FLOOD3 with some improvements. The analysis results by the newly proposed hot leg break model in the COMET is in the same trend as those observed in scaled-down integral experiment. And the analyses results for the UCN 3 and 4 by COMET are qualitatively and quantitatively in good agreement with those predicted by best-estimate analysis by using RELAP5/MOD3. Therefore, the COMET code is validated and can be used for the licensing analysis. 6 tabs., 82 figs., 9 refs. (Author)

This paper describes the comparison results of sizing performance for two systems. The KHNP developed a new eddy current testing system for the inspection of steam generator tubing in domestic nuclear power plants. The equivalency assessment of the newly developed system with the EPRI-qualified system was already carried out. In this paper, the comparisons of depth-sizing performance for the artificial flaws between two systems were performed. The results show that the newly developed system is in good agreement with the qualified system. Therefore, it is expected that the newly developed eddy current system can be used for the inspection of steam generator tubing in nuclear power plants. There are some non-destructive examination (NDE) methods for the inspection of components in nuclear power plants, such as ultrasonic, radiographic, eddy current testing, etc. The eddy current testing is widely used for the inspection of steam generator (SG) tubing because it offers a relatively low cost approach for high speed, large scale testing of metallic materials in high pressure and temperature engineering systems. The Korea Hydro and Nuclear Power Co., Ltd. (KHNP) developed an eddy current testing system for the inspection of steam generator tubing in nuclear power plants. This system includes not only hardware but software such as the frequency generator and data acquisition-analysis program. The foreign eddy current system developed by ZETEC is currently used for the inspection of steam generator tubing in domestic nuclear power plants. The equivalency assessment between two systems was already carried out in accordance with the EPRI steam generator examination guidelines.

The purpose of this study was to examine the prevalence of workplace violence toward newly licensed nurses and the relationship between workplace violence and job outcomes. An online survey was conducted of newly licensed registered nurses who had obtained their license in 2012 or 2013 in South Korea and had been working for 5-12 months after first being employed. The sample consisted of 312 nurses working in hospitals or clinics. The Copenhagen Psychosocial Questionnaire II was used to measure violence and nurse job outcomes. Multiple linear and logistic regression analyses were conducted to examine the relationship between violence and job outcomes. Verbal abuse was most prevalent (59.6%), followed by threats of violence (36.9%), physical violence (27.6%), bullying (25.6%), and sexual harassment (22.4%). Approximately three quarters of the nurses had experienced at least one type of violence. The main perpetrators were patients and nurse colleagues, although the distribution of perpetrators varied depending on the type of violence. Bullying had a significant relationship with all four job outcomes (job satisfaction, burnout, commitment to the workplace, and intent to leave), while verbal abuse was associated with all job outcomes except for intent to leave. Violence perpetrated by nurse colleagues had a significant relationship with all four job outcomes, while violence by physicians had a significant inverse relationship with job satisfaction. Workplace violence is experienced by a high percentage of newly licensed nurses, and is associated with their job outcomes. Copyright © 2016. Published by Elsevier B.V.

To determine the timing and magnitude of revenues generated by newly recruited faculty, to facilitate configuration of recruitment packages appropriately matched to expected financial returns. The aggregate of all positive cash flows to central college of medicine administration -- from research, clinical care, tuition, philanthropy, and royalties and patents, from all faculty newly recruited to the University of Arizona College of Medicine between 1998 and 2004 -- was quantified using the net present value (npv) methodology, which incorporates the time value of money. Tenure-track faculty and, in particular, those with laboratory research programs, generated the highest positive central cash flows. The npv for positive cash flows (npv[+]) during 6 and 10 years for newly recruited assistant professors with laboratory research programs were $118,600 and $255,400, respectively, and, for professors with laboratory research programs, $172,600 and $298,000, respectively (associate professors were not analyzed because of limited numbers). Faculty whose appointments at the University of Arizona College of Medicine exceeded 15 years in duration were the most productive in central revenue generation, far in excess of their numbers proportionate to the total. The results emphasize the critical importance of faculty retention, because even those newly recruited faculty who are most successful in central revenue generation (tenure track with laboratory research programs) must be retained for periods well in excess of 10 years to recoup the initial central investment required for their recruitment.

Fu Weijie; Wei Haiqing; Liu Yuxin

2008-01-01

The gravity-mode (g-mode) eigenfrequencies of newly born strange quark stars (SQSs) and neutron stars (NSs) are studied. It is found that the eigenfrequencies in SQSs are much lower than those in NSs by almost 1 order of magnitude, since the components of a SQS are all extremely relativistic particles while nucleons in a NS are nonrelativistic. We therefore propose that newly born SQSs can be distinguished from the NSs by detecting the eigenfrequencies of the g-mode pulsations of supernovae cores through gravitational radiation by LIGO-class detectors

Full Text Available Abstract Background Bacterial lipases received much attention for their substrate specificity and their ability to function in extreme environments (pH, temperature.... Many staphylococci produced lipases which were released into the culture medium. Reports of thermostable lipases from Staphylococcus sp. and active in alkaline conditions are not previously described. Results A newly soil-isolated Staphylococcus sp. strain ESW secretes an induced lipase in the culture medium. The effects of temperature, pH and various components in a detergent on the activity and stability of Staphylococcus sp. lipase (SL1 were studied in a preliminary evaluation for use in detergent formulation solutions. The enzyme was highly active over a wide range of pH from 9.0 to 13.0, with an optimum at pH 12.0. The relative activity at pH 13.0 was about 60% of that obtained at pH 12.0. It exhibited maximal activity at 60°C. This novel lipase, showed extreme stability towards non-ionic and anionic surfactants after pre-incubation for 1 h at 40°C, and relative stability towards oxidizing agents. Additionally, the crude enzyme showed excellent stability and compatibility with various commercial solid and liquid detergents. Conclusions These properties added to the high activity in high alkaline pH make this novel lipase an ideal choice for application in detergent formulations.

Fully microscopic many-body calculations are used to study the influence of strong sub-picosecond pulses on the carrier distributions and corresponding optical response in saturable absorbers used for mode-locking—semiconductor (quantum well) saturable absorber mirrors (SESAMs) and single layer graphene based saturable absorber mirrors (GSAMs). Unlike in GSAMs, the saturation fluence and recovery time in SESAMs show a strong spectral dependence. While the saturation fluence in the SESAM is minimal at the excitonic bandgap, the optimal recovery time and least pulse distortion due to group delay dispersion are found for excitation higher in the first subband. For excitation near the SESAM bandgap, the saturation fluence is about one tenth of that in the GSAM. At energies above the bandgap, the fluences in both systems become similar. A strong dependence of the saturation fluence on the pulse width in both systems is caused by carrier relaxation during the pulse. The recovery time in graphene is found to be about two to four times faster than that in the SESAMs. The occurrence of negative differential transmission in graphene is shown to be caused by dopant related carriers. In SESAMs, a negative differential transmission is found when exciting below the excitonic resonance where excitation induced dephasing leads to an enhancement of the absorption. Comparisons of the simulation data to the experiment show a very good quantitative agreement.

Profiles of alpha-melanocyte-stimulating hormone (alpha-MSH) in the Japanese flounder were examined by a newly developed time-resolved fluoroimmunoassay (TR-FIA) and immunohistochemistry. A TR-FIA for alpha-MSH was newly developed, and its levels in the pituitary gland and plasma of Japanese flounder reared in a white or black tank for 5 months were compared. A competitive assay using two antibodies was performed among secondary antibodies in the solid phase, alpha-MSH antibodies, samples, and europium-labeled Des-Ac-alpha-MSH. The sensitivity of the assay, defined as twice the standard deviation at a zero dose, was 0.98 ng/ml (49 pg/well). The intra- and interassay coefficients of variation of the assay were 8.8% (n=8) and 17.3% (n=5), respectively, at about 50% binding. Cross-reactivities of Des-Ac-alpha-MSH and Di-Ac-alpha-MSH were about 100%. Cross-reactivities of adrenocorticotropic hormone, salmon gonadotropin-releasing hormone (sGnRH), and chicken GnRH-II were less than 0.2%, and that of melanin-concentrating hormone was less than 2.0% at 50% binding. Displacement curves of serially twofold-diluted hypothalamus extract, pituitary gland extract, and plasma extract of Japanese flounder with the assay buffer were parallel to the alpha-MSH standard curve. Moreover, displacement curves of serially twofold-diluted hypothalamus and/or pituitary gland extract of masu salmon, goldfish, red seabream, Japanese eel, tiger puffer, and barfin flounder with the assay buffer were also parallel to the alpha-MSH standard. In Japanese flounder, total immunoreactive (ir)-alpha-MSH levels in the pituitary gland were lower in the black tank, whereas those in the plasma tended to be higher in the black tank, suggesting that the synthesis and release of alpha-MSH are higher in the black tank. alpha-MSH-ir cells were detected in the pars intermedia and a small part of the pars distalis of the pituitary gland. alpha-MSH-ir cell bodies were located in the basal hypothalamus and alpha

In this study we applied a smart biomaterial formed from a self-assembling, multi-functional synthetic peptide amphiphile (PA) to coat substrates with various surface chemistries. The combination of PA coating and alignment-inducing functionalised substrates provided a template to instruct human corneal stromal fibroblasts to adhere, become aligned and then bio-fabricate a highly-ordered, multi-layered, three-dimensional tissue by depositing an aligned, native-like extracellular matrix. The newly-formed corneal tissue equivalent was subsequently able to eliminate the adhesive properties of the template and govern its own complete release via the action of endogenous proteases. Tissues recovered through this method were structurally stable, easily handled, and carrier-free. Furthermore, topographical and mechanical analysis by atomic force microscopy showed that tissue equivalents formed on the alignment-inducing PA template had highly-ordered, compact collagen deposition, with a two-fold higher elastic modulus compared to the less compact tissues produced on the non-alignment template, the PA-coated glass. We suggest that this technology represents a new paradigm in tissue engineering and regenerative medicine, whereby all processes for the bio-fabrication and subsequent self-release of natural, bio-prosthetic human tissues depend solely on simple template-tissue feedback interactions.

The unique properties of engineered nanomaterials led to their increased production and potential release into the environment. Currently available environmental fate models developed for traditional contaminants are limited in their ability to simulate nanomaterials' environmental behavior. This is due to an incomplete understanding and representation of the processes governing nanomaterial distribution in the environment and by scarce empirical data quantifying the interaction of nanomaterials with environmental surfaces. The well-known Water Quality Analysis Simulation Program (WASP) was updated to incorporate nanomaterial-specific processes, specifically hetero-aggregation with particulate matter. In parallel with this effort, laboratory studies were used to quantify parameter values parameters necessary for governing processes in surface waters. This presentation will discuss the recent developments in the new architecture for WASP8 and the newly constructed Advanced Toxicant Module. The module includes advanced algorithms for increased numbers of state variables: chemicals, solids, dissolved organic matter, pathogens, temperature, and salinity. This presentation will focus specifically on the incorporation of nanomaterials, with the applications of the fate and transport of hypothetical releases of Multi-Walled Carbon Nanotubes (MWCNT) and Graphene Oxide (GO) into the headwaters of a southeastern US coastal plains river. While this presentation focuses on nanomaterials, the advanced toxicant module can also simulate metals and organic contaminants.

Purpose: For small field dosimetry, such as measurements of output factors for cones or MLC-shaped irregular small fields, ion chambers often Result in an underestimation of the dose, due to both the volume averaging effect and the lack of lateral charged particle equilibrium. This work presents a mathematical model for correction matrix for a PTW PinPoint ionization chamber for dosimetric measurements made in the newly released Incise™ Multileaf collimator fields of the CyberKnife M6™ machine. Methods: A correction matrix for a PTW 0.015cc PinPoint ionization chamber was developed by modeling its 3D dose response in twelve cone-shaped circular fields created using the 5mm, 7.5mm, 10mm, 12.5mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 50mm, 60mm cones in a CyberKnife M6™ machine. For each field size, hundreds of readings were recorded for every 2mm chamber shift in the horizontal plane. The contribution of each dose pixel to a measurement point depended on the radial distance and the angle to the chamber axis. These readings were then compared with the theoretical dose as obtained with Monte Carlo calculation. A penalized least-square optimization algorithm was developed to generate the correction matrix. After the parameter fitting, the mathematical model was validated for MLC-shaped irregular fields. Results: The optimization algorithm used for parameter fitting was stable and the resulted response factors were smooth in spatial domain. After correction with the mathematical model, the chamber reading matched with the calculation for all the tested fields to within 2%. Conclusion: A novel mathematical model has been developed for PinPoint chamber for dosimetric measurements in small MLC-shaped irregular fields. The correction matrix is dependent on detector, treatment unit and the geometry of setup. The model can be applied to non-standard composite fields and provides an access to IMRT point dose validation.

Full Text Available Background/Aim. Retention of fissure sealants and good adaptation to enamel are essential for their success. Fluoride releasing resin-based materials are widely accepted for pit and fissure sealing, but newly designed glass ionomers can serve as a good alternative. The aim of this study was to evaluate microleakage and sealing ability in vitro, and to clinically assess two fluoride releasing fissure sealants. Methods. The sample for experimental study consisted of 20 freshly extracted intact human third molars, divided in two experimental groups according to the sealing material: fluoride releasing resin-based (Heliosel F and glass ionomer (Fuji Triage material. Digital images and scanning electron microscope were used to assess microleakage and adaptation ability. Sample for clinical study consisted of 60 children, aged 6-8 years, with high caries risk, divided in two groups according to the sealant material. Fissure sealant was applied to all erupted, caries-free first permanent molars. Sealants were evaluated after 3, 6 and 12 months using modified Ryge criteria for retention, marginal adaptation, colour match, surface smoothness and caries. Results. Microleakage was detected in more than half of the specimen, without significant differences between the two groups (p > 0.05. Both materials exhibited acceptable sealing ability. Complete retention at the end of the observation period was 81.8% for resin-based, and 21.1% for glass-ionomer fissure sealant (p < 0.001. The presence of caries in sealed molars has been detected in one patient in both groups. During the 12-month observation period, Helioseal F demonstrated better retention, marginal adaptation and surface smoothness (p < 0.001. There were no differences between the two materials regarding caries and color match (p > 0.05. Conclusion. Both tested materials demonstrate satisfactory clinical and caries prophylactic characteristics that justify their use in contemporary preventive
Distinct presynaptic regulation of dopamine release through NMDA receptors in striosome- and matrix-enriched areas of the rat striatum

Striosome- and matrix-enriched striatal zones were defined in coronal and sagittal brain sections of the rat, on the basis of {sup 3}H-naloxone binding to mu-opiate receptors (a striosome-specific marker). Then, using a new in vitro microsuperfusion device, the NMDA (50 microM)-evoked release of newly synthesized {sup 3}H-dopamine ({sup 3}H-DA) was examined in these four striatal areas under Mg(2+)-free conditions. The amplitudes of the responses were different in striosomal (171 +/- 6% and 161 +/- 5% of the spontaneous release) than in matrix areas (223 +/- 6% and 248 +/- 12%), even when glycine (1 or 100 microM) was coapplied (in the presence of 1 microM strychnine). In the four areas, the NMDA-evoked release of {sup 3}H-DA was blocked completely by Mg{sup 2}{sup +} (1 mM) or (+)-5-methyl-10,11-dihydro-5H-dibenzo(a,d)cyclohepten-5,10-imine maleate (MK-801; 1 microM) and almost totally abolished by kynurenate (100 microM). Because the tetrodotoxin (TTX)-resistant NMDA-evoked release of {sup 3}H-DA was similar in striosome- (148 +/- 5% and 152 +/- 6%) or matrix-enriched (161 +/- 5% and 156 +/- 7%) areas, the indirect (TTX-sensitive) component of NMDA-evoked responses, which involves striatal neurons and/or afferent fibers, seems more important in the matrix- than in the striosome-enriched areas. The modulation of DA release by cortical glutamate and/or aspartate-containing inputs through NMDA receptors in the matrix appears thus to be partly distinct from that observed in the striosomes, providing some functional basis for the histochemical striatal heterogeneity.

Microencapsulated controlled-release preparations of nimesulide were formulated. Microparticles were prepared by modified phase separation (non-solvent addition) technique using different ratios of ethylcellulose. The microparticles (M/sub 1/, M/sub 2/, and M/sub 3/) were yellow, free flowing and spherical in shape with the particle size varying from 93.62 +- 14.15 to 104.19 +- 18.15 mu m. The t/sub 60%/of nimesulide release from microparticles was found to be 3 +- 0.6, 5 +- 0.6 and 8 +- 0.8 h for formulations M/sub 1/, M/sub 2/, and M/sub 3/, respectively. FT-IR, XRD, and thermal analysis were done which showed that there is no interaction between the polymer and drug. The mechanism of drug release from nimesulide microparticles was studied by using Higuchi and Korsmeyer-Peppas models. The value of coefficient of determination (R/sup 2/) for M/sub 1/, M/sub 2/, and M/sub 3/ indicates anomalous and case-II transport release mechanism. The dissolution data of designed system verified its ability to maintain plasma concentration without the need of frequent dosing. The Nimesulide microparticles prolonged drug release for 12 hours or longer. Based on the results of release studies, M/sub 3/ was opted as a suitable microparticulate formulation allowing the controlled release of nimesulide over a prolonged period of time. Moreover, its encapsulation efficiency was also comparable to the other two formulations (M/sub 1/ and M/sub 2/). In conclusion, the influence of polymer concentration should be considered during formulation development. (author)

To study the psycho-social risk factors of sexual failure among newly married young males in the Uyghur population. We conducted a paired case control study of 186 newly married Uyghur young males (aged 17－30 ［23.4±2.9］ yr) with sexual failure and another 186 (aged 18－34 ［24.0±3.1］ yr) with no such problem as controls. We performed a logistic regression analysis on the possible psycho-social risk factors of this condition. Logistic regression analysis showed that the risk factors of sexual failure among the newly married men included personality (OR=0.271, 95% CI 0.176－0.420), income (OR=0.391, 95% CI 0.264－0.580), history of masturbation (OR=0.824, 95% CI 0.710－0.956), premarital sex (OR=0.757, 95% CI 0.677－0.847), sense of obligation (OR=1.756, 95% CI 1.157－2.693), equality of the social status (OR=0.574, 95% CI 0.435－0.756), degree of mutual care (OR=1.605, 95% CI 1.268－2.032), female's psychological obstacle (OR=2.832, 95% CI 1.221－6.569), and religion (OR=0.643, 95% CI 0.472－0.967). There was a statistical significance in the correlation between these factors and sexual failure in the newly married males (all Ppsycho-social factors, which necessitates sexual education among young males and particularly pre-marriage sexual education and psychological guide among both males and females.

2017-12-01

This study aimed to analyze the impact of increasing the supply of newly licensed nurses on improving the hospital nurse staffing grades for the period of 2009~2014. Using public administrative data, we analyzed the effect of newly licensed nurses on staffing in 1,594 hospitals using Generalized Estimating Equation (GEE) ordered logistic regression, and of supply variation on improving staffing grades in 1,042 hospitals using GEE logistic regression. An increase of one newly licensed nurse per 100 beds in general units had significantly lower odds of improving staffing grades (grades 6~0 vs. 7) (odds ratio=0.95, p=.005). The supply of newly licensed nurses increased by 32% from 2009 to 2014, and proportion of hospitals whose staffing grade had improved, not changed, and worsened was 19.1%, 70.1%, and 10.8% respectively. Compared to 2009, the supply variation of newly licensed nurses in 2014 was not significantly related to the increased odds of improving staffing grades in the region (OR=1.02, p=.870). To achieve a balance in the regional supply and demand for hospital nurses, compliance with nurse staffing legislation and revisions in the nursing fee differentiation policy are needed. Rather than relying on increasing nurse supply, retention policies for new graduate nurses are required to build and sustain competent nurse workforce in the future. © 2017 Korean Society of Nursing Science

Hope is important to cancer patients as it helps them deal with their diagnosis. Little is known about hope in newly diagnosed cancer patients. Based on the Transcending Possibilities conceptual model of hope, the purpose of this study was to examine the relationship of hope with pain, energy, and psychological and demographic characteristics in newly diagnosed adult oncology outpatients. Data from 310 New Patient Assessment Forms from cancer outpatients' health records were collected. Health records from the first six months of 2009 were reviewed and data were collected on hope, energy, pain, depression, anxiety, feeling overwhelmed, and demographic variables. A generalized linear modeling approach was used to study the relationship of hope scores with these variables. Hypothesized variables and variables that were significant at the P = 0.01 level from the univariate analysis were entered into the multivariate model, with hope scores as the dependent variable. Hope scores were significantly negatively related to age (P = 0.02). More specifically, oncology patients who were 65 years of age or older had significantly less hope than those under the age of 65 years (P = 0.01). Gender (P = 0.009) also was a significant factor, with men having higher hope scores than women. No other variables were significant. Older adults comprise the majority of persons in Canada with cancer. The lower hope scores found in this age group compared with their younger counterparts underscore the importance of further research. This study provides a foundation for future research in this important area for oncology patients. Copyright © 2013 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc. All rights reserved.

The objective of the study was to formulate and evaluate controlled release polymeric tablets of Diclofenac Potassium for the release rate, release patterns and the mechanism involved in the release process of the drug. Formulations with different types and grades of Ethyl Cellulose Ether derivatives in several drug-to-polymer ratios (D:P) were compressed into tablets using the direct compression method. In vitro drug release studies were performed in phosphate buffer (pH 7.4) as dissolution medium by using USP Method-1 (Rotating Basket Method). Similarity factor f2 and dissimilarity factor f1 were applied for checking the similarities and dissimilarities of the release profiles of different formulations. For the determination of the release mechanism and drug release kinetics various mathematical/kinetic models were employed. It was found that all of the Ethocel polymers could significantly slow down the drug release rate with Ethocel FP polymers being the most efficient, especially at D:P ratios of 10:03 which lead towards the achievement of zero or near zero order release kinetics.

Although chitosan (CS) has been recognized as a good material for colon-specific drug delivery systems, an overcoating with an enteric coating polymer on the surface of CS is absolutely necessary because CS is soluble in acidic conditions before reaching the colon. In the present study, to improve its stability in the presence of acid, a newly developed CS-laurate (CS-LA) material was evaluated as a coating dispersion for the development of colon-specific drug delivery systems. Two types of CS with different molecular weights, CS250 and CS600, were used to prepare CS-LA films by the casting method. The CS250-LA films had smooth surfaces, whereas the surfaces of the CS600-LA films were rough, indicating that the CS250-LA dispersion could form a denser film than CS600-LA. Both of these CS-LA films maintained a constant shape over 22 h in a pH 1.2 HCl/NaCl buffer, where the corresponding CS films rapidly disintegrated. In addition, the CS250-LA film showed specific colon degradability in a pH 6.0 phosphate buffered solution containing 1.0% (w/v) β-glucosidase. As a result of tensile strength and elongation at the break, both CS-LA films were found to have flexible film properties. Finally, the release of acetaminophen from disks coated with CS250-LA dispersions was significantly suppressed in fluids at pH 1.2 and 6.8, whereas disks coated with CS solution rapidly released the drug in pH 1.2 fluids. Taken together, this study shows that LA modification could be a useful approach in preparing CS films with acid stability and colonic degradability properties without requiring overcoating.

Stimuli-responsive capsules are of interest in drug delivery, fragrance release, food preservation, and self-healing materials. Many methods are used to trigger the release of encapsulated contents. Here we highlight mechanisms for the controlled release of encapsulated cargo that utilize chemical reactions occurring in solid polymeric shell walls. Triggering mechanisms responsible for covalent bond cleavage that result in the release of capsule contents include chemical, biological, light, thermal, magnetic, and electrical stimuli. We present methods for encapsulation and release, triggering methods, and mechanisms and conclude with our opinions on interesting obstacles for chemically induced activation with relevance for controlled release.

Experimental releases of mosquitoes are performed to understand characteristics of populations related to the biology, ability to transmit pathogens, and ultimately their control. In this article, we discuss considerations related to the safety of experimental releases of living mosquitoes, applying principles of good practice in vector biology that protect human health and comfort. We describe specific factors of experimental releases of mosquitoes that we believe are critical to inform institutional biosafety committees and similar review boards to which proposals to conduct mosquito release experiments have been submitted. In this study, "experimental releases" means those that do not significantly increase vector capacity or nuisance biting relative to the unperturbed natural baseline. This document specifically does not address releases of mosquitoes for ongoing control programs or trials of new control methods for which broader assessments of risk are required. It also does not address releases of transgenic or exotic (non-native) mosquito species, both of which require particular regulatory approval. Experimental releases may include females and males and evaluation must consider their effects based on the number released, their genotype and phenotype, the environment into which they are released, and postrelease collection activities. We consider whether increases of disease transmission and nuisance biting might result from proposed experimental releases against the backdrop of natural population size variation. We recommend that experimental releases be conducted in a manner that can be reasonably argued to have insignificant negative effects. Reviewers of proposals for experimental releases should expect applicants to provide such an argument based on evidence from similar studies and their planned activities. This document provides guidance for creating and evaluating such proposals.

Cell adhesion molecules are key regulators of atherosclerotic plaque development, but circulating levels of soluble fragments, such as intercellular adhesion molecule (sICAM-1) and vascular cell adhesion molecule (sVCAM-1), have yielded conflicting associations with atherosclerotic cardiovascular disease (ASCVD). Endothelial cell-selective adhesion molecule (ESAM) is expressed exclusively in platelets and endothelial cells, and soluble ESAM (sESAM) levels have been associated with prevalent subclinical atherosclerosis. We therefore hypothesized that sESAM would be associated with incident ASCVD. sESAM, sICAM-1, and sVCAM-1 were measured in 2,442 participants without CVD in the Dallas Heart Study, a probability-based population sample aged 30-65 years enrolled between 2000 and 2002. ASCVD was defined as first myocardial infarction, stroke, coronary revascularization, or CV death. A total of 162 ASCVD events were analyzed over 10.4 years. Increasing sESAM was associated with ASCVD, independent of risk factors (HR Q4 vs Q1: 2.7, 95% CI 1.6-4.6). Serial adjustment for renal function, sICAM-1, VCAM-1, and prevalent coronary calcium did not attenuate these associations. Continuous ESAM demonstrated similar findings (HR 1.31, 95% CI 1.2-1.4). Addition of sESAM to traditional risk factors improved discrimination and reclassification (delta c-index: P = .009; integrated-discrimination-improvement index P = .001; net reclassification index = 0.42, 95% CI 0.15-0.68). Neither sICAM-1 nor sVCAM-1 was independently associated with ASCVD. sESAM but not sICAM-1 or sVCAM-1 levels are associated with incident ASCVD. Further studies are warranted to investigate the role of sESAM in ASCVD. Copyright © 2017 Elsevier Inc. All rights reserved.

Secondary school. Qualitative study. A total of 31 newly credentialed ATs (6 men, 25 women; mean age = 24 ± 3 years) participated. Of these, 17 ATs (4 men, 13 women; mean age = 25 ± 4 years) were employed full time in the secondary school setting, and 14 ATs (2 men, 12 women; mean age = 23.0 ± 2.0 years) were graduate assistant students in the secondary school setting. All participants completed semistructured interviews, which focused on their experiences in the secondary school setting and transitioning into the role and setting. Transcripts were analyzed using the phenomenologic approach. Creditability was established by peer review, member checks, and researcher triangulation. Four main findings related to the professional commitment of newly credentialed ATs in the secondary school setting were identified. Work-life balance, professional relationships formed with the student-athletes, enjoyment gained from working in the secondary school setting, and professional responsibility emerged as factors facilitating commitment. Affective commitment is a primary facilitator of professional commitment. Newly credentialed ATs who enjoy their jobs and have time to engage in nonwork roles are able to maintain a positive professional commitment. Our findings align with the previous literature and help strengthen our understanding that rejuvenation and passion are important to professional commitment.

This paper presents an overview of the activities being planned and implemented to certify newly generated contact handled transuranic (TRU) waste produced by Los Alamos National Laboratory's (LANL's) Plutonium Facility. Certifying waste at the point of generation is the most important cost and labor saving step in the WIPP certification process. The pedigree of a waste item is best known by the originator of the waste and frees a site from expensive characterization activities such as those associated with legacy waste. Through a cooperative agreement with LANLs Waste Management Facility and under the umbrella of LANLs WIPP-related certification and quality assurance documents, the Plutonium Facility will be certifying its own newly generated waste. Some of the challenges faced by the Plutonium Facility in preparing to certify TRU waste include the modification and addition of procedures to meet WIPP requirements, standardizing packaging for TRU waste, collecting processing documentation from operations which produce TRU waste, and developing ways to modify waste streams which are not certifiable in their present form

Sulawesi microplate Island is located at famous triple junction area of the Eurasian, India-Australian, and Philippine Sea plates. Under the influence of the northward moving Australian plate and the westward motion of the Philippine plate, the island at Eastern part of Indonesia is collide and with the Eurasian plate and Sunda Block. Those recent microplate tectonic motions can be quantitatively determine by GNSS-GPS measurement. We use combine GNSS-GPS observation types (campaign type and continuous type) from 1997 to 2015 to derive newly velocity field of the area. Several strategies are applied and tested to get the optimum result, and finally we choose regional strategy to reduce error propagation contribution from global multi baseline processing using GAMIT/GLOBK 10.5. Velocity field are analyzed in global reference frame ITRF 2008 and local reference frame by fixing with respect alternatively to Eurasian plate - Sunda block, India-Australian plate and Philippine Sea plates. Newly results show dense distribution of velocity field. This information is useful for tectonic deformation studying in geospatial era.

To demonstrate the biodegradation of dibenzofuran (DF) and its structural analogs by a newly isolated Agrobacterium sp. PH-08. To assess the biodegradation potential of newly isolated Agrobacterium sp. PH-08, various substrates were evaluated as sole carbon sources in growth and biotransformation experiments. ESI LC-MS/MS analysis revealed the presence of angular degrading by-products as well as lateral dioxygenation metabolites in the upper pathway. The metabolites in the lower pathway also were detected. In addition, the cometabolically degraded daughter compounds of DF-related compounds such as BP and dibenzothiophene (DBT) in dual substrate degradation were observed. Strain PH-08 exhibited the evidence of meta-cleavage pathway as confirmed by the activity and gene expression of catechol-2,3-dioxygenase. Newly isolated bacterial strain, Agrobacterium sp. PH-08, grew well with and degraded DF via both angular and lateral dioxygenation as demonstrated by metabolites identified through ESI LC-MS/MS and GC-MS analyses. The other heterocyclic pollutants were also cometabolically degraded. Few reports have described the complete degradation of DF by a cometabolic lateral pathway. Our study demonstrates the novel results that the newly isolated strain utilized the DF as a sole carbon source and mineralized it via multiple dioxygenation. © 2013 The Society for Applied Microbiology.

Full Text Available The nutritional values of three vegetable oils were evaluated on the basis of the growth response, the food efficiency ratio and the effect on mental activity. Avocado, sesame and coconut oil were the only sources of fat in the experimental diets fed to three groups of albino mice. Mice fed with avocado and sesame yielded higher body weight gains and food efficiency ratios than mice fed with coconut oil. This agrees with the reports made on the study of these oils by the biological assay. The values for the mental activity of mice fed with avocado and sesame diets were also higher. However, mice fed with avocado diet showed relatively higher values than those fed with sesame. It is possible that the content of essential fatty acids among others could be directly related to intellectual performance.

Characterization of newly isolated lytic bacteriophages active against Acinetobacter baumannii.

Directory of Open Access Journals (Sweden)

Maia Merabishvili

Full Text Available Based on genotyping and host range, two newly isolated lytic bacteriophages, myovirus vB_AbaM_Acibel004 and podovirus vB_AbaP_Acibel007, active against Acinetobacter baumannii clinical strains, were selected from a new phage library for further characterization. The complete genomes of the two phages were analyzed. Both phages are characterized by broad host range and essential features of potential therapeutic phages, such as short latent period (27 and 21 min, respectively, high burst size (125 and 145, respectively, stability of activity in liquid culture and low frequency of occurrence of phage-resistant mutant bacterial cells. Genomic analysis showed that while Acibel004 represents a novel bacteriophage with resemblance to some unclassified Pseudomonas aeruginosa phages, Acibel007 belongs to the well-characterized genus of the Phikmvlikevirus. The newly isolated phages can serve as potential candidates for phage cocktails to control A. baumannii infections.

2010-01-01

The purpose of this article is to carry out, a discussion on the subject of bioethics and cadavers based upon a critic review of literature. A review of literature, was made with a survey of articles between 1977 and 2007 in the sites 'Biblioteca Virtual de Saúde', PubMed and SciElo, utilizing the keywords: newly deceased patients, newly dead patients, simulators,. This was complemented by a critical evaluation of books published in the area of ethics and bioethics. The possibility to develop learning without orientation by a supervisor is doubtful.. The utilization of newly dead for learning invasive procedures is very frequent and seldom admitted. These procedures, are usually, carried out secretly, without the knowledge and consent of the family. The ethical aspects of these practices are not discussed in the practical medical education. It essential that the ethics of use of recent deceased become a necessary content of graduate education. Performance of these procedures by students should always be authorized by family members. The simulators meet the requirements of training. Discussions about the ethical and bioethical aspects cannot be separated from practical considerations during the students learning time.

Aedes albopictus male survival in laboratory cages is no more than 4-5 days when kept without any access to sugar indicating their need to feed on a sugar source soon after emergence. We therefore developed a device to administer energetic substances to newly emerged males when released as pupae as part of a sterile insect technique (SIT) programme, made with a polyurethane sponge 4 cm thick and perforated with holes 2 cm in diameter. The sponge was imbibed with the required sugar solution and due to its high retention capacity the sugar solution was available for males to feed for at least 48 h. When evaluated in lab cages, comparing adults emerged from the device with sugar solution vs the device with water only (as negative control), about half of the males tested positive for fructose using the Van Handel anthrone test, compared to none of males in the control cage. We then tested the tool in semi-field and in field conditions with different sugar concentrations (10%, 15%, and 20%) and compared results to the controls fed with water only. Males were recaptured by a battery operated manual aspirator at 24 and 48 h after pupae release. Rather high share 10-25% of captured males tested positive for fructose in recollections in the vicinity of the control stations, while in the vicinity of the sugar stations around 40-55% of males were positive, though variability between replicates was large. The sugar positive males in the control test may have been released males that had access to natural sugar sources found close to the release station and/or wild males present in the environment. Only a slight increase in the proportion of positive males was obtained by increasing the sugar concentration in the feeding device from 10% to 20%. Surprisingly, modification of the device to add a black plastic inverted funnel above the container reduced rather than increased the proportion of fructose positive males collected around the station. No evidence of difference in the

This is the second installment for the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) Quasar Survey, which includes quasars observed from 2013 September to 2015 June. There are 9024 confirmed quasars in DR2 and 10911 in DR3. After cross-match with the Sloan Digital Sky Survey (SDSS) quasar catalogs and NED, 12126 quasars are discovered independently. Among them, 2225 quasars were released by SDSS DR12 QSO catalog in 2014 after we finalized the survey candidates. 1801 sources were identified by SDSS DR14 as QSOs. The remaining 8100 quasars are considered as newly founded, and among them, 6887 quasars can be given reliable emission line measurements and the estimated black hole masses. Quasars found in LAMOST are mostly located at low-to-moderate redshifts, with a mean value of 1.5. The highest redshift observed in DR2 and DR3 is 5. We applied emission line measurements to Hα, Hβ, Mg II, and C IV. We deduced the monochromatic continuum luminosities using photometry data, and estimated the virial black hole masses for the newly discovered quasars. Results are compiled into a quasar catalog, which will be available online.

ATP Release Channels

Full Text Available Adenosine triphosphate (ATP has been well established as an important extracellular ligand of autocrine signaling, intercellular communication, and neurotransmission with numerous physiological and pathophysiological roles. In addition to the classical exocytosis, non-vesicular mechanisms of cellular ATP release have been demonstrated in many cell types. Although large and negatively charged ATP molecules cannot diffuse across the lipid bilayer of the plasma membrane, conductive ATP release from the cytosol into the extracellular space is possible through ATP-permeable channels. Such channels must possess two minimum qualifications for ATP permeation: anion permeability and a large ion-conducting pore. Currently, five groups of channels are acknowledged as ATP-release channels: connexin hemichannels, pannexin 1, calcium homeostasis modulator 1 (CALHM1, volume-regulated anion channels (VRACs, also known as volume-sensitive outwardly rectifying (VSOR anion channels, and maxi-anion channels (MACs. Recently, major breakthroughs have been made in the field by molecular identification of CALHM1 as the action potential-dependent ATP-release channel in taste bud cells, LRRC8s as components of VRACs, and SLCO2A1 as a core subunit of MACs. Here, the function and physiological roles of these five groups of ATP-release channels are summarized, along with a discussion on the future implications of understanding these channels.

2016-03-01

The first year turnover rate for newly licensed registered nurses is roughly 30% and increases to about 57% in the second year (Twibell et al., 2012). An effective preceptorship has been shown to better facilitate the first year transition (Hodges et al., 2008) and increase retention rates (Pine and Tart, 2007). The purpose of this study was to examine the relationships between newly licensed registered nurses' perceived preceptor role effectiveness, psychological empowerment and professional autonomy. A prospective, cross-sectional, descriptive research design was used. Sixty-nine newly licensed registered nurses were recruited and surveyed. Newly licensed registered nurses were found to have moderately high levels of perceived preceptor role effectiveness, psychological empowerment, and professional autonomy. Preceptor role effectiveness had significant, moderately, positive relationships with professional autonomy and psychological empowerment. There was also a significant relationship found between professional autonomy and psychological empowerment. Results show that preceptor role effectiveness is linked to increased professional autonomy and psychological empowerment. Therefore, effective preceptorships are necessary in easing the newly licensed registered nurse's transition to practice. Strategies to ensure effective preceptorships and enhance the NRLN's transition to practice are proposed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Chen, Xi; Lee, Dong Sun; Zhu, Xuntao; Yam, Kit L

This paper investigated the feasibility of manipulating packaging polymers with various degrees of hydrophobicity to release two antioxidants, tocopherol and quercetin, at rates suitable for long-term inhibition of lipid oxidation in food. For example, one antioxidant can be released at a fast rate to provide short-term/intermediate protection, whereas the other antioxidant can be released at a slower rate to provide intermediate/long-term protection of lipid oxidation. Controlled-release packaging films containing tocopherol and quercetin were produced using ethylene vinyl alcohol (EVOH), ethylene vinyl acetate (EVA), low-density polyethylene (LDPE), and polypropylene (PP) polymers; the release of these antioxidants to 95% ethanol (a fatty food simulant) was measured using UV-vis spectrophotometry, and Fickian diffusion models with appropriate initial and boundary conditions were used to fit the data. For films containing only quercetin, the results show that the release of quercetin was much faster but lasted for a much shorter time for hydrophilic polymers (EVOH and EVA) than for hydrophobic polymers (LDPE and PP). For binary antioxidant films containing tocopherol and quercetin, the results show that tocopherol released more rapidly but for a shorter period of time than quercetin in LDPE and EVOH films, and the difference is more pronounced for LDPE films than EVOH films. The results also show the presence of tocopherol can accelerate the release of quercetin. Although none of the films produced is acceptable for long-term lipid oxidation inhibition, the study provides encouraging results suggesting that acceptable films may be produced in the future using polymer blend films.

The Stockholm Convention on Persistent Organic Pollutants (POPs) entered into force on 17 May 2004 with 50 Parties. In May 2004, 59 countries had ratified or acceded the Convention. The objective of the Convention is ''to protect human health and the environment from persistent organic pollutants''. For intentionally produced POPs, e.g., pesticides and industrial chemicals such as hexachlorobenzene and polychlorinated biphenyls, this will be achieved by stop of production and use. For unintentionally generated POPs, such as polychlorinated dibenzo-pdioxins (PCDD) and polychlorinated dibenzofurans (PCDF), measures have to be taken to ''reduce the total releases derived from anthropogenic sources''; the final goal is ultimate elimination, where feasible. Under the Convention, Parties have to establish and maintain release inventories to prove the continuous release reduction. Since many countries do not have the technical and financial capacity to measure all releases from all potential PCDD/PCDF sources, UNEP Chemicals has developed the ''Standardized Toolkit for the Identification of Quantification of Dioxin and Furan Releases'' (''Toolkit'' for short), a methodology to estimate annual releases from a number of sources. With this methodology, annual releases can be estimated by multiplying process-specific default emission factors provided in the Toolkit with national activity data. At the seventh session of the Intergovernmental Negotiating Committee, the Toolkit was recommended to be used by countries when reporting national release data to the Conference of the Parties. The Toolkit is especially used by developing countries and countries with economies in transition where no measured data are available. Results from Uruguay, Thailand, Jordan, Philippines, and Brunei Darussalam have been published.

To investigate the influence of parental sociodemographic, communication, and psychological factors on sperm collection attempts among at-risk adolescent males newly diagnosed with cancer. Prospective, single group, observational study design. Pediatric oncology centers. Parents (N = 144) of 122 newly diagnosed adolescent males at increased risk for infertility secondary to cancer therapy. Survey-based assessment of parent factors associated with adolescent collection attempts. Attempt of manual collection of sperm. Parental recommendation to bank sperm (odds ratio [OR] 3.72; 95% confidence interval [CI] 1.18-11.76) and perceived self-efficacy to facilitate banking (OR 1.20; 95% CI 1.02-1.41) were associated with an increased likelihood of making a collection attempt. Parental recommendation to bank is a critical influence for sperm banking among adolescent males newly diagnosed with cancer. These findings highlight the importance of effective communication between parents, patients, and health-care teams when discussing preservation options. Parent perceptions of their ability to facilitate sperm banking at the time of diagnosis should also be targeted in future interventions. NCT01152268. Copyright © 2017. Published by Elsevier Inc.

Guar (GG) and Karaya gums (KG) alone and in combination with hydroxy-propylmethylcellulose (HPMC) were evaluated as release retarding materials to formulate a controlled-release tablet dosage form of isoniazid (1). In vitro release of 1 from tablets followed non-Fickian release profile with rapid initial release. Urinary excretion studies in normal subjects showed steady-state levels of 1 for 13 h. In vitro and in vivo data correlated (r = 0.9794). The studies suggested the potentiality of GG and KG as release retarding materials in formulating controlled-release tablet dosage forms of 1.

Impaired immune responses in skin play a pivotal role in the development and progression of chemical-associated inflammatory skin disorders. In this study, we synthesized new flavonoid derivatives from macakurzin C, and identified in vitro and in vivo efficacy of a potent anti-inflammatory flavonoid, Compound 14 (CPD 14), with its underlying mechanisms. In lipopolysaccharide (LPS)-stimulated murine macrophages and IFN-γ/TNF-α-stimulated human keratinocytes, CPD 14 significantly inhibited the release of inflammatory mediators including nitric oxide (NO), prostaglandins, and cytokines (IC{sub 50} for NO inhibition in macrophages: 4.61 μM). Attenuated NF-κB signaling and activated Nrf2/HO-1 pathway were responsible for the anti-inflammatory effects of CPD 14. The in vivo relevance was examined in phorbol 12-myristate 13-acetate (TPA)-induced acute skin inflammation and oxazolone-induced atopic dermatitis models. Topically applied CPD 14 significantly protected both irritation- and sensitization-associated skin inflammation by suppressing the expression of inflammatory mediators. In summary, we demonstrated that a newly synthesized flavonoid, CPD 14, has potent inhibitory effects on skin inflammation, suggesting it is a potential therapeutic candidate to treat skin disorders associated with excessive inflammation. - Highlights: • An anti-inflammatory flavonoid CPD 14 was newly synthesized from macakurzin C. • CPD 14 potently inhibited inflammatory reaction in keratinocytes and macrophages. • Dermal toxicity by irritation or sensitization in rats was protected by CPD 14. • Attenuated NF-κB and activated Nrf2/HO-1 were main mechanisms of CPD 14 action.

The purpose of this design analysis is to specify and document the total and respirable fractions for radioactive materials that are released from an accident event at the Monitored Geologic Repository (MGR) involving commercial spent nuclear fuel (CSNF) in a dry environment. The total and respirable release fractions will be used to support the preclosure licensing basis for the MGR. The total release fraction is defined as the fraction of total CSNF assembly inventory, typically expressed as an activity inventory (e.g., curies), of a given radionuclide that is released to the environment from a waste form. The radionuclides are released from the inside of breached fuel rods (or pins) and from the detachment of radioactive material (crud) from the outside surfaces of fuel rods and other components of fuel assemblies. The total release fraction accounts for several mechanisms that tend to retain, retard, or diminish the amount of radionuclides that are available for transport to dose receptors or otherwise can be shown to reduce exposure of receptors to radiological releases. The total release fraction includes a fraction of airborne material that is respirable and could result in inhalation doses. This subset of the total release fraction is referred to as the respirable release fraction. Potential accidents may involve waste forms that are characterized as either bare (unconfined) fuel assemblies or confined fuel assemblies. The confined CSNF assemblies at the MGR are contained in shipping casks, canisters, or disposal containers (waste packages). In contrast to the bare fuel assemblies, the container that confines the fuel assemblies has the potential of providing an additional barrier for diminishing the total release fraction should the fuel rod cladding breach during an accident. However, this analysis will not take credit for this additional bamer and will establish only the total release fractions for bare unconfined CSNF assemblies, which may however be
