    2010-02-01

    Anatomical variations of the great saphenous vein, femoral artery and femoral vein at the inguinal level are rare. Modifications in the anatomical relationships among theses vessel can cause technical difficulties. There are two reports in the literature of the complete transposition of the femoral artery and vein. Both patients had large varicose veins only in the limb that presented the variation, which suggested an extrinsic compression. In the present paper, we report a case study of a patient with an incomplete transposition of the femoral artery and vein. Specifically, the common femoral vein and the saphenofemoral junction were completely overlapped by the common femoral artery. Although this anatomical variation did not present any clinical signs, it required a more complex surgical procedure. PMID:20224538

  2. Creation of an Arterio-Venous Fistula Between the Brachial Artery and Basilic Vein with a Saphenous Vein Graft Interposition

    Full Text Available Arteriovenous fistulas for hemodialysis are usually open in the upper extremity. For patients with thrombosed arteriovenous fistulas in this area, alternative fistula access routes are needed. AVF creation with a saphenous vein graft is an alternative hemodialysis access method in the patient who has lost the chance of fistula creation with his native vessels.The aim of this case report is to discuss AV fistula management with a saphenous vein graft between the brachial artery and basilic vein in a hemodialysisdependent patient. In this patient previous fistulas were thrombosed and the native vessels in the upper extremity vessels were not suitable for a new AV fistula creation.

    In microvascular reconstructive surgery the patency of the recipient vessels is the key to successful outcome. In head and neck surgery there is often a lack of adequate recipient vessels as a result of chemoradiation therapy and ablative surgery. To overcome this it is crucial to identify vessels of adequate length and diameter outside the field of injury. We report our experience with cephalic vein transposition for drainage of seven free flaps--six intestinal and one osteocutaneous--for head and neck reconstruction. In five cases the cephalic vein was used during the free flap transfer and in two cases in salvage re-exploration surgery. All flaps survived completely. The anatomical course and location of the cephalic vein allow good patency and straightforward harvesting. Its vascular properties are predictive of reduced incidence of complications such as flap congestion and failure. We suggest that the cephalic vein offers a high venous flow drainage system for large free flaps and advocate its use in free intestinal transfer in the vessel-depleted neck as well as in re-exploration surgery.

  4. Transposition of cephalic vein to rescue hemodialysis access arteriovenous fistula and treat symptomatic central venous obstruction

    2014-03-01

    Full Text Available It is known that stenosis or central venous obstruction affects 20 to 50% of patients who undergo placement of catheters in central veins. For patients who are given hemodialysis via upper limbs, this problem causes debilitating symptoms and increases the risk of loss of hemodialysis access. We report an atypical case of treatment of a dialysis patient with multiple comorbidities, severe swelling and pain in the right upper limb (RUL, few alternative sites for hemodialysis vascular access, a functioning brachiobasilic fistula in the RUL and severe venous hypertension in the same limb, secondary to central vein occlusion of the internal jugular vein and right brachiocephalic trunk. The alternative surgical treatment chosen was to transpose the RUL cephalic vein, forming a venous necklace at the anterior cervical region, bypassing the site of venous occlusion. In order to achieve this, we dissected the cephalic vein in the right arm to its junction with the axillary vein, devalved the cephalic vein and anastomosed it to the contralateral external jugular vein, providing venous drainage to the RUL, alleviating symptoms of venous hypertension and preserving function of the brachiobasilic fistula.

    2008-01-01

    Many properties of partial transposition are unclear as yet.Here we carefully consider the number of the negative eigenvalues of ρT(ρ's partial transposition)when ρ is a two-partite state.There is strong evidence to show that the number of negative eigenvalues of ρT is N(N-1)/2 at most when ρ is a state in Hilbert space CM(×)CN.For the special case,the 2×2 system,we use this result to give a partial proof of the conjecture |ρT|T≥0.We find that this conjecture is strongly connected with the entanglement of the state corresponding to the negative eigenvalue of ρT or the negative entropy of ρ.

  10. Revealing Maximal Diameter of Upper Limb Superficial Vein with an Elevated Environmental Temperature.

    2016-01-01

    Ultrasonography is the primary tool for preoperative analysis of vein morphology for fistula creation in patients with end-stage renal disease. This study examines the effect of environmental temperature on the superficial vein size. Superficial veins of thirteen healthy volunteers were marked at three sites: cephalic vein in left lateral arm near cubital fossa, cephalic vein in left forearm at wrist, and basilic vein in left medial arm near cubital fossa. Mean diameters were recorded using ultrasound probe at 26°C and 43°C. Body temperature was increased using a Bair Hugger blanket. Mean values from the two temperatures were analyzed using paired sample t-test. All three superficial vein sites displayed statistically significant increase in diameter when the temperature was increased from 26°C to 43°C. Paired t-test showed p values of 0.001 for cephalic vein at wrist, 0.01 for cephalic vein near cubital fossa, and 0.01 for basilic vein near cubital fossa. This study proved that environmental temperature exerts a statistically significant effect on vein size measured by ultrasound during preoperative assessment for vascular access. Not to the extent of 43°C, the authors would recommend setting the room temperature higher during ultrasound vascular assessment to avoid underestimating the superficial vein size. PMID:27597987

    Yeşiloğlu, Yeşim; Şit, Latifşah

    2012-09-01

    Water, ethanol and acetone extracts from leaves and flowers of purple basil, one of the most popular spices consumed in the Thrace region of Turkey, were tested in vitro for their ability to inhibit peroxidation of lipids, to scavenge DPPH, hydrogen peroxide, superoxide anion, to reduce Fe(III) to Fe(II) and to chelate Fe(II) ions. The results showed that purple basil contained naturally occurring antioxidant components and possessed antioxidant activity which may be attributed to its lipid peroxidation inhibitory, radical scavenging and metal chelating activities. It was concluded that purple basil might be a potential source of antioxidants.

  16. Transposition of the great arteries

    Castela Eduardo

    2008-10-01

    Full Text Available Abstract Transposition of the great arteries (TGA, also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA discordance. The incidence is estimated at 1 in 3,500–5,000 live births, with a male-to-female ratio 1.5 to 3.2:1. In 50% of cases, the VA discordance is an isolated finding. In 10% of cases, TGA is associated with noncardiac malformations. The association with other cardiac malformations such as ventricular septal defect (VSD and left ventricular outflow tract obstruction is frequent and dictates timing and clinical presentation, which consists of cyanosis with or without congestive heart failure. The onset and severity depend on anatomical and functional variants that influence the degree of mixing between the two circulations. If no obstructive lesions are present and there is a large VSD, cyanosis may go undetected and only be perceived during episodes of crying or agitation. In these cases, signs of congestive heart failure prevail. The exact aetiology remains unknown. Some associated risk factors (gestational diabetes mellitus, maternal exposure to rodenticides and herbicides, maternal use of antiepileptic drugs have been postulated. Mutations in growth differentiation factor-1 gene, the thyroid hormone receptor-associated protein-2 gene and the gene encoding the cryptic protein have been shown implicated in discordant VA connections, but they explain only a small minority of TGA cases. The diagnosis is confirmed by echocardiography, which also provides the morphological details required for future surgical management. Prenatal diagnosis by foetal echocardiography is possible and desirable, as it may improve the early neonatal management and reduce morbidity and mortality. Differential diagnosis includes other causes of central neonatal cyanosis. Palliative treatment with prostaglandin E1 and balloon atrial septostomy are usually

    Objective To study the optimal position and method for ovarian transposition and its benefits and indications.Methods We performed ovarian transposition in 34 patients from August 1989 to December 2000. Twelve patients were diagnosed with stage Ⅰb to Ⅱa cervical cancer, 4 had stage Ⅰa endometrial carcinoma, 12 had stage Ⅲ to Ⅳ endometriosis, 4 had myoma of uterus, 1 had dysfunctional uterine bleeding, and 1 had an ovarian granulosa cell tumor. Surgery went as follows: the ovary was dissociated by clamp, the skin was incised and a tunnel was made, then the ovary was translocated to the subcutaneous site. In the cases of benign lesions, the ovarian vessel pedicel went in through the abdominal cavity, but in malignant tumors, it went out through the peritoneum. Results In both cases (benign lesions or malignant tumors), the short-term and long-term endocrine function of the translocated ovary remained normal. Furthermore, patients could supervise their translocated ovary themselves.Conclusions Subcutaneous ovary transposition might prevent not only implantation of gastrointestinal cancer but also the extension of pelvic carcinoma to the ovary. Because of the shallow transposition and the incision scar, it is easy for patients to supervise themselves. Moreover, the site of the ovary is easy to locate for ultrasound examinations. Thus, it can obtain the goal of early prevention for cancer. Subcutaneous ovarian transposition with skin incision is the optimal selection and suitable for all patients with various gynecologic diseases in which ovary removal is not necessary.

  19. Transposition of teeth: A forensic perspective

    Supriya Nambiar

    2014-01-01

    Full Text Available Dental identification plays a key role in mass casualties and is usually based on disturbances of tooth eruption, malocclusions and/or previous dental treatments, changes brought about by age, pathological conditions and developmental disturbances. Tooth transposition is a disturbance of tooth eruption and is defined as change in the position of two adjacent teeth within the same quadrant. This review aims to discuss the prevalence and the etiology of transposition through a literature survey and to discuss its importance and implications as pertaining to the field of forensics. In summary, transposition is a rare and severe positional anomaly that represents a challenge for a dentist. It requires a keen eye on the part of the forensic pathologist to identify the condition.

    This document discusses, among other things, a stator with transposition between the windings or coils. The coils are free from transposition to increase the fill factor of the stator slots. The transposition at the end connections between an inner coil and an outer coil provide transposition to reduce circulating current loss. The increased fill factor reduces further current losses. Such a stator is used in a dual rotor, permanent magnet machine, for example, in a compressor pump, wind turbine gearbox, wind turbine rotor.

    2015-06-01

    Downy mildew, caused by the oomycete Peronospora belbahrii, is a devastating disease of sweet basil. In this study, 113 accessions of Ocimum species (83 Plant Introduction entries and 30 commercial entries) were tested for resistance against downy mildew at the seedling stage in growth chambers, and during three seasons, in the field. Most entries belonging to O. basilicum were highly susceptible whereas most entries belonging to O. americanum, O. kilimanadascharicum, O. gratissimum, O. campechianum, or O. tenuiflorum were highly resistant at both the seedling stage and the field. Twenty-seven highly resistant individual plants were each crossed with the susceptible sweet basil 'Peri', and the F1 progeny plants were examined for disease resistance. The F1 plants of two crosses were highly resistant, F1 plants of 24 crosses were moderately resistant, and F1 plants of one cross were susceptible, suggesting full, partial, or no dominance of the resistance gene(s), respectively. These data confirm the feasibility of producing downy mildew-resistant cultivars of sweet basil by crossing with wild Ocimum species. PMID:25844828

  7. Surgical transposition of the ovary: Radiologic appearance

    Therapeutic irradiation of the pelvis of a young female patient will result in loss of ovarian function. In a surgical technique termed ovarian transposition, the ovary is repositioned to the iliac fossa or paracolic gutter outside the radiation field. The computed tomographic (CT) scans and sonograms of five patients with cervical carcinoma who underwent this procedure were reviewed. The normal transposed ovary was of soft-tissue attenuation, often with one or more small cysts. Large cysts developed in the ovaries of three patients. One cyst was functional, another was due to a mesothelial inclusion cyst, and the third was most probably related to the transposition itself. Since the transposed ovary is difficult to palpate, CT or sonography can be used to demonstrate and follow up a cystic mass. Recognition of the appearance and location of the transposed ovary is important to avoid misinterpretation of a solid or cystic mass in patients who are at risk for tumor recurrence

  12. Effects of biocides on chlorophyll contents of detached basil leaves

    Titima Arunrangsi

    2013-06-01

    Full Text Available Herbicides and insecticides have been widely and intensively used in agricultural areas worldwide to enhance crop yield. However, many biocides cause serious environmental problems. In addition, the biocides may also have some effects on the treated agricultural crops. To study effects of biocides on chlorophyll content in detached basil leaves, 2,4-D dimethylamine salt (2,4 D-Amine, paraquat, carbosulfan, and azadirachtin, were chosen as representatives of biocide. After applying the chemicals to detached basil leaves overnight in darkness, chlorophyll contents were determined. Only treatment with 2,4 D-Amine resulted in reduction of chlorophyll contents significantly compared to treatment with deionized (DI water. In the case of paraquat and carbosulfan, chlorophyll contents were not significantly changed, while slightly higher chlorophyll contents, compared to DI water, after the treatment with azadirachtin, were observed. The results indicated that 2,4 D-Amine shows an ability to accelerate chlorophyll degradation, but azadirachtin helps to retard chlorophyll degradation, when each biocide is used at the concentration recommended by the manufacturer.

  13. Riboregulation of bacterial and archaeal transposition.

    Ellis, Michael J; Haniford, David B

    2016-05-01

    The coexistence of transposons with their hosts depends largely on transposition levels being tightly regulated to limit the mutagenic burden associated with frequent transposition. For 'DNA-based' (class II) bacterial transposons there is growing evidence that regulation through small noncoding RNAs and/or the RNA-binding protein Hfq are prominent mechanisms of defense against transposition. Recent transcriptomics analyses have identified many new cases of antisense RNAs (asRNA) that potentially could regulate the expression of transposon-encoded genes giving the impression that asRNA regulation of DNA-based transposons is much more frequent than previously thought. Hfq is a highly conserved bacterial protein that plays a central role in posttranscriptional gene regulation and stress response pathways in many bacteria. Three different mechanisms for Hfq-directed control of bacterial transposons have been identified to date highlighting the versatility of this protein as a regulator of bacterial transposons. There is also evidence emerging that some DNA-based transposons encode RNAs that could regulate expression of host genes. In the case of IS200, which appears to have lost its ability to transpose, contributing a regulatory RNA to its host could account for the persistence of this mobile element in a wide range of bacterial species. It remains to be seen how prevalent these transposon-encoded RNA regulators are, but given the relatively large amount of intragenic transcription in bacterial genomes, it would not be surprising if new examples are forthcoming.

    Wyenandt, Christian A; Simon, James E; Pyne, Robert M; Homa, Kathryn; McGrath, Margaret T; Zhang, Shouan; Raid, Richard N; Ma, Li-Jun; Wick, Robert; Guo, Li; Madeiras, Angela

    2015-07-01

    Basil (Ocimum spp.) is one of the most economically important and widely grown herbs in the world. Basil downy mildew, caused by Peronospora belbahrii, has become an important disease in sweet basil (O. basilicum) production worldwide in the past decade. Global sweet basil production is at significant risk to basil downy mildew because of the lack of genetic resistance and the ability of the pathogen to be distributed on infested seed. Controlling the disease is challenging and consequently many crops have been lost. In the past few years, plant breeding efforts have been made to identify germplasm that can be used to introduce downy mildew resistance genes into commercial sweet basils while ensuring that resistant plants have the correct phenotype, aroma, and tastes needed for market acceptability. Fungicide efficacy studies have been conducted to evaluate current and newly developed conventional and organic fungicides for its management with limited success. This review explores the current efforts and progress being made in understanding basil downy mildew and its control. PMID:25894318

  18. Nocturnal Fanning Suppresses Downy Mildew Epidemics in Sweet Basil

    Cohen, Yigal; Ben-Naim, Yariv

    2016-01-01

    Downy mildew is currently the most serious disease of sweet basil around the world. The oomycete causal agent Peronospora belbahrii requires ≥ 4h free leaf moisture for infection and ≥7.5h of water-saturated atmosphere (relative humidity RH≥95%) at night for sporulation. We show here that continued nocturnal fanning (wind speed of 0.4–1.5 m/s) from 8pm to 8am dramatically suppressed downy mildew development. In three experiments conducted during 2015, percent infected leaves in regular (non-fanned) net-houses reached a mean of 89.9, 94.3 and 96.0% compared to1.2, 1.7 and 0.5% in adjacent fanned net-houses, respectively. Nocturnal fanning reduced the number of hours per night with RH≥95% thus shortened the dew periods below the threshold required for infection or sporulation. In experiments A, B and C, the number of nights with ≥4h of RH≥95% was 28, 10 and 17 in the non-fanned net-houses compared to 5, 0 and 5 in the fanned net-houses, respectively. In the third experiment leaf wetness sensors were installed. Dew formation was strongly suppressed in the fanned net-house as compared to the non-fanned net-house. Healthy potted plants became infected and sporulated a week later if placed one night in the non-fanned house whereas healthy plants placed during that night in the fanned house remained healthy. Infected potted basil plants sporulated heavily after one night of incubation in the non-fanned house whereas almost no sporulation occurred in similar plants incubated that night in the fanned house. The data suggest that nocturnal fanning is highly effective in suppressing downy mildew epidemics in sweet basil. Fanning prevented the within-canopy RH from reaching saturation, reduced dew deposition on the leaves, and hence prevented both infection and sporulation of P. belbahrii. PMID:27171554

    2013-03-01

    Full Text Available ABSTRACT: The aerial parts essential oils of Ocimum basilicum (Lamiaceae from Togo were steam-distilled and investigated for their percentage composition (GC and GC/MS and in vitro antimicrobial activities. Five oil chemotypes were identified and classified as follows in line with their principal components: estragole type; linalool/estragole type; methyleugenol type; methyleugenol/t-anethole type; tanethole type. The in vitro microbiological experiments revealed that only the methyleugenol and methyleugenol/t-anethole chemotypes were active against tested fungi and bacteria. Their minimum inhibitory concentrations (MIC ranged from 80-150 μL/L and from 200-500 μL/L respectively. Likewise, on tested bacteria the MIC varied from 200-400 μL/L and from 250-500 μL/L respectively. These findings are supportive of the potential of both basil oil chemotypes for use as active ingredients in natural antibiotic drugs.

    2013-07-01

    Full Text Available Premise of the study: Demand for fresh-market sweet basil continues to increase, but in 2009 a new pathogen emerged, threatening commercial field/greenhouse production and leading to high crop losses. This study describes a simple and effective staining method for rapid microscopic detection of basil downy mildew (Peronospora belbahrii from leaves of basil (Ocimum basilicum. Methods and Results: Fresh leaf sections infected with P. belbahrii were placed on a microscope slide, cleared with Visikol™, and stained with iodine solution followed by one drop of 70% sulfuric acid. Cell walls of the pathogen were stained with a distinct coloration, providing a high-contrast image between the pathogen and plant. Conclusions: This new staining method can be used successfully to identify downy mildew in basil, which then can significantly reduce its spread if identified early, coupled with mitigation strategies. This technique can facilitate the control of the disease, without expensive and specialized equipment.

    2012-12-01

    Full Text Available Investigations carried out in 2005-2006 related to the growth, flowering, and yielding of selected basil (Ocimum basilicum L. varieties. The most important biometric traits, number of days from sowing till flowering, size of fresh and air-dried herb weight, and essential oil content in dried material, were determined. Great morphological and developmental as well as chemical composition differentiation was found for studied basil varieties. Plants of 'Sweet' cv. were characterized by the largest height (53.4 cm and side shoot number (16, 'Lemon' - by the largest plant diameter (42.3 cm. The number of days till flowering depended on weather conditions and the variety, and it amounted from 44 to 126. Basil flowers were white, pink, and violet. Herb yield depended on the variety and growth conditions. Differences in the amount and yield of essential oil from basil were also recorded. The largest amounts of oil (1.55% were accumulated by 'Bush' cv.

    Antitumor, antimicrobial and antioxidant activities of basil were studied, along with its characterization in phenolic compounds, organic acids and soluble sugars. The results placed basil as a valuable candidate for functionalization and conservation of food products, maintaining their nutritional properties, while increasing their shelf life and potential health effects. The basil leaves were then incorporated in "Serra da Estrela Cheese", either in its dehydrated form or as a decoction. The cheeses were then subject to a nutritional evaluation, being characterized for their fatty acids, minerals and CIE color parameters. To assess the combined effects of plant incorporation and storage time, a 2-way ANOVA was used to process the results, further analysed through a linear discriminant analysis. Overall, basil leaves provided antioxidant activity to the cheeses, reduced the moisture, and preserved the unsaturated fatty acids and proteins. Comparing both incorporation types, the decoctions had a higher functionalizing and conservative effect. PMID:27080879

  6. Keeler's theorem and products of distinct transpositions

    Evans, Ron; Nguyen, Tuan

    2012-01-01

    An episode of Futurama features a two-body mind-switching machine which will not work more than once on the same pair of bodies. After the Futurama community indulges in a mind-switching spree, the question is asked, "Can the switching be undone so as to restore all minds to their original bodies?" Ken Keeler found an algorithm that undoes any mind-scrambling permutation with the aid of two "outsiders". We refine Keeler's result by providing a more efficient algorithm that uses the smallest possible number of switches. We also present best possible algorithms for undoing two natural sequences of switches, each sequence effecting a cyclic mind-scrambling permutation in the symmetric group S_n. Finally, we give necessary and sufficient conditions on m and n for the identity permutation to be expressible as a product of m distinct transpositions in S_n.

  7. Lateralization Technique and Inferior Alveolar Nerve Transposition

    Sanches, Marco Antonio; Ramalho, Gabriel Cardoso; Manzi, Marcello Roberto

    2016-01-01

    Bone resorption of the posterior mandible can result in diminished bone edge and, therefore, the installation of implants in these regions becomes a challenge, especially in the presence of the mandibular canal and its contents, the inferior alveolar nerve. Several treatment alternatives are suggested: the use of short implants, guided bone regeneration, appositional bone grafting, distraction osteogenesis, inclined implants tangential to the mandibular canal, and the lateralization of the inferior alveolar nerve. The aim was to elucidate the success rate of implants in the lateralization technique and in inferior alveolar nerve transposition and to determine the most effective sensory test. We conclude that the success rate is linked to the possibility of installing implants with long bicortical anchor which favors primary stability and biomechanics. PMID:27433360

    2009-12-01

    Full Text Available Abstract Background hAT elements and V(DJ recombination may have evolved from a common ancestral transposable element system. Extrachromosomal, circular forms of transposable elements (referred to here as episomal forms have been reported yet their biological significance remains unknown. V(DJ signal joints, which resemble episomal transposable elements, have been considered non-recombinogenic products of V(DJ recombination and a safe way to dispose of excised chromosomal sequences. V(DJ signal joints can, however, participate in recombination reactions and the purpose of this study was to determine if hobo and Hermes episomal elements are also recombinogenic. Results Up to 50% of hobo/Hermes episomes contained two intact, inverted-terminal repeats and 86% of these contained from 1-1000 bp of intercalary DNA. Episomal hobo/Hermes elements were recovered from Musca domestica (a natural host of Hermes, Drosophila melanogaster (a natural host of hobo and transgenic Drosophila melanogaster and Aedes aegypti (with autonomous Hermes elements. Episomal Hermes elements were recovered from unfertilized eggs of M. domestica and D. melanogaster demonstrating their potential for extrachromosomal, maternal transmission. Reintegration of episomal Hermes elements was observed in vitro and in vivo and the presence of Hermes episomes resulted in lower rates of canonical Hermes transposition in vivo. Conclusion Episomal hobo/Hermes elements are common products of element excision and can be maternally transmitted. Episomal forms of Hermes are capable of integration and also of influencing the transposition of canonical elements suggesting biological roles for these extrachromosomal elements in element transmission and regulation.

  10. Portal Vein Thrombosis

    Ronny Cohen

    2015-01-01

    Full Text Available Portal vein thrombosis (PVT is the blockage or narrowing of the portal vein by a thrombus. It is relatively rare and has been linked with the presence of an underlying liver disease or prothrombotic disorders. We present a case of a young male who presented with vague abdominal symptoms for approximately one week. Imaging revealed the presence of multiple nonocclusive thrombi involving the right portal vein, the splenic vein, and the left renal vein, as well as complete occlusion of the left portal vein and the superior mesenteric vein. We discuss pathogenesis, clinical presentation, and management of both acute and chronic thrombosis. The presence of PVT should be considered as a clue for prothrombotic disorders, liver disease, and other local and general factors that must be carefully investigated. It is hoped that this case report will help increase awareness of the complexity associated with portal vein thrombosis among the medical community.

  12. The response of sweet basil (Ocimum basilicum L. to the application of growth stimulators and forecrops

    Cezary A. Kwiatkowski

    2012-12-01

    Full Text Available A field experiment in growing sweet basil was carried out in the period 2008-2010 in Fajsławice (Lublin region, on podzolic soil. The study evaluated the biometric traits of the plants, yield, the qualitative parameters of herbal raw material and weed infestation of the crop in dependence on growth simulators (Asahi SL, Bio-algeen, Titanit and the forecrop (winter wheat or spring barley + white mustard cover crop. Plots without foliar application of the growth stimulators were the control treatment. Tillage, mineral NPK fertilization as well as mechanical and chemical weed control were typical for this plant species and consistent with the recommendations for herbal plant protection. A hypothesis was made that the application of growth stimulators would have a positive effect on basil productivity, raw material quality and weed infestation of the basil crop. It was also assumed that the phytosanitary and fertilizing effects of the cover crop would result in higher and qualitatively better yield compared to the cereal forecrop alone (winter wheat. The best quantitative parameters of sweet basil raw material and the highest reduction in air-dry weight of weeds in the crop were observed after the application of the growth stimulators. The forecrop - spring barley + a white mustard cover crop that is ploughed in - also had a beneficial effect on yield and weed infestation of the plant in question. The traditional crop protection method used in the basil crop, without the application of the growth stimulators, resulted in a lower plant height and a smaller number of shoots per plant. This caused higher weed infestation of the crop and a decrease in yield. The positive side of the non-application of growth stimulators was a better chemical composition of basil raw material. Asahi SL and Tytanit yielded the best growth and productivity of the basil plants.

  13. Evaluation of holy basil mouthwash as an adjunctive plaque control agent in a four day plaque regrowth model

    Acharya, Anirudh B.; Vij, Chhavi; Trivedi, Dhiraj; Setty, Swati B.; Thakur, Srinath L.

    2014-01-01

    Objectives: Various antibacterial and antiplaque agents are used in chemical plaque control but none are without their shortcomings. Chlorhexidine considered a gold standard, also has an array of side effects. To overcome these, numerous herbal extracts have been tried and tested and one among them is holy basil. The present study evaluated the antibacterial efficacy of holy basil in vitro against some periodontopathogens and its antiplaque effect in vivo. Study Design: Thirty periodontally healthy volunteers were randomly divided into three groups and refrained from all mechanical oral hygiene measures for 4 days and used one of the randomly assigned mouthwash (1- chlorhexidine; 2- holy basil; and 3- sterile water [placebo]) twice daily. The Plaque Index (PI) was assessed at days 0 and 5. Aqueous extract of holy basil was tested against Prevotella intermedia (P. intermedia) and Fusobacterium nucleatum (F.nucleatum). Results: Holy basil extract showed inhibition of both the tested periodontopathogens (P.intermedia and F.nucleatum) at various concentrations. In all groups, the PI increased from baseline to day 5. There was a statistically significant difference (p < .05) between the chlorhexidine and placebo rinse and the holy basil and placebo rinse, but no statistically significant difference was found between the chlorhexidine and holy basil rinse with respect to PI. Conclusions: These results indicate that the holy basil mouthwash has an antiplaque effect and is efficacious against P. intermedia and F. nucleatum strains in vitro. Hence holy basil mouthwash may have potential as an antiplaque mouthwash with prophylactic benefits. Key words:Antibacterial agent, basil, Fusobacterium nucleatum, mouthwashes, Prevotella intermedia.

  14. Chemical composition of the essential oil of basil (Ocimum basilicum L. Lamiaceae

    Jelačić Slavica Ć.

    2011-01-01

    Full Text Available In Serbia basil has been grown traditionally as a decorative, medicinal, seasoning and ritual herb, and there is a variety of different populations of basil. Basil is considered to have been brought to Serbia in the 12th century by monks returning from their pilgrimages. Essential oils isolated from herb of ten basil populations traditionally grown on the territory of the Republic of Serbia have been analyzed. The selected populations have been designated under codes from T-1 to T-10 and deposited in the Plant Genes Bank at Serbia and at the Institute for Crop Sciences of the Faculty of Agriculture in Belgrade. Essential oils of all tested basil populations were light yellow and had a specific aromatic scent. The composition of essential oil in the dry herb of the tested populations ranged from 0.87 to 1.84%. The results of gas chromatographic analysis of essential oils in tested basil populations pointed to their complex chemical composition and to the fact that they belong to the most appreciated European chemotype. In total thirty three components have been identified in the essential oils. The most common fraction of components in all tested oils was terpenoides. The predominant component in all essential oils is monoterpen linalol, ranging from 51.52 to 74.73%. Phenylpropranoid methylchavicol ranged from 2.49 to 18.97%. Essential oils of populations T-6, T-7, T-8 and T-10 were characterized by elevated 1.8-cineol (4.44, 3.70, 4.01 and 3.43%, respectively. Populations T-3 and T-4 in essential oil contained higher percent of geraniol (4.27 and 3.31%, respectively. In all ten essential oils sesquiterpen fraction consisted of greater number of components, with germacrene having special significance as it was found in high percentage in all populations. The highest content of germacrene was registered in population T-9 (4.30%, T-10 (4.18%, while in others it ranged from 2.17 to 3.69%. Basil populations traditionally grown in Serbia have

  15. Surgery for transposition of great arteries: A historical perspective

    Supreet P Marathe

    2015-01-01

    Full Text Available The history of surgery for transposition of great arteries (TGA has paralleled the history of cardiac surgery. In fact, it began before the birth of open heart surgery when the palliative Blalock-Hanlon septectomy was first performed in 1948. The atrial switch, which was an attempt to correct the physiology of transposition, had significant shortcomings. The arterial switch sought to address them. This has emerged as an anatomically as well as physiologically appropriate solution. Today we continue to pursue technical refinements as well as try to expand the indications of the arterial switch. This review traces the various milestones in this perpetual journey.

  19. Structure and reaction mechanism of basil eugenol synthase.

    Gordon V Louie

    Full Text Available Phenylpropenes, a large group of plant volatile compounds that serve in multiple roles in defense and pollinator attraction, contain a propenyl side chain. Eugenol synthase (EGS catalyzes the reductive displacement of acetate from the propenyl side chain of the substrate coniferyl acetate to produce the allyl-phenylpropene eugenol. We report here the structure determination of EGS from basil (Ocimum basilicum by protein x-ray crystallography. EGS is structurally related to the short-chain dehydrogenase/reductases (SDRs, and in particular, enzymes in the isoflavone-reductase-like subfamily. The structure of a ternary complex of EGS bound to the cofactor NADP(H and a mixed competitive inhibitor EMDF ((7S,8S-ethyl (7,8-methylene-dihydroferulate provides a detailed view of the binding interactions within the EGS active site and a starting point for mutagenic examination of the unusual reductive mechanism of EGS. The key interactions between EMDF and the EGS-holoenzyme include stacking of the phenyl ring of EMDF against the cofactor's nicotinamide ring and a water-mediated hydrogen-bonding interaction between the EMDF 4-hydroxy group and the side-chain amino moiety of a conserved lysine residue, Lys132. The C4 carbon of nicotinamide resides immediately adjacent to the site of hydride addition, the C7 carbon of cinnamyl acetate substrates. The inhibitor-bound EGS structure suggests a two-step reaction mechanism involving the formation of a quinone-methide prior to reduction. The formation of this intermediate is promoted by a hydrogen-bonding network that favors deprotonation of the substrate's 4-hydroxyl group and disfavors binding of the acetate moiety, akin to a push-pull catalytic mechanism. Notably, the catalytic involvement in EGS of the conserved Lys132 in preparing the phenolic substrate for quinone methide formation through the proton-relay network appears to be an adaptation of the analogous role in hydrogen bonding played by the equivalent

  20. Daytime Solar Heating Controls Downy Mildew Peronospora belbahrii in Sweet Basil.

    Cohen, Yigal; Rubin, Avia E

    2015-01-01

    The biotrophic oomycete Peronospora belbahrii causes a devastating downy mildew disease in sweet basil. Due to the lack of resistant cultivars current control measures rely heavily on fungicides. However, resistance to fungicides and strict regulation on their deployment greatly restrict their use. Here we report on a 'green' method to control this disease. Growth chamber studies showed that P. belbahrii could hardly withstand exposure to high temperatures; exposure of spores, infected leaves, or infected plants to 35-45 °C for 6-9 hours suppressed its survival. Therefore, daytime solar heating was employed in the field to control the downy mildew disease it causes in basil. Covering growth houses of sweet basil already infected with downy mildew with transparent infra-red-impermeable, transparent polyethylene sheets raised the daily maximal temperature during sunny hours by 11-22 °C reaching 40-58 °C (greenhouse effect). Such coverage, applied for a few hours during 1-3 consecutive days, had a detrimental effect on the survival of P. belbahrii: killing the pathogen and/or suppressing disease progress while enhancing growth of the host basil plants.

Areal parts, especially leaves of sweet basil are widely used to enhance the flavour of foods such as salads, pasta, tomato products, vegetables, pizza, meat, soups, marine foods, confectioneries and other products. Essential oil yield and chemical components of two Iranian landraces of sweet basil including “Purple” and “Green” grown south-central of Iran (Isfahan province were investigated. The hydro-distillated oils were analyzed by GC-MS. The oil yields were obtained from the aerial of Purple with 0.56 ml/100 g dry matter and the aerial of Green with 0.48 ml/100 g dry matter. Results indicated significant differences (p < 0.01 among the aerial for the main constituents in the essential oil from two Iranian landraces of sweet basil. The major constituents of the essential oil from the aerial of Purple landrace were methyl chavicol or estragol (63.32% and linalool (7.96%. The main compositions of the essential oil from the aerial of Green landrace were methyl chavicol (31.82%, geranial (24.60% and neral (22.65%. Genarlly, a comparison of our results with the previous reports suggests differences in the essential oil compositions and oil yield of the plant material could be attributed to genetic diversity in two Iranian landraces of sweet basil.

  5. Pulmonary blood flow distribution in transposition of the great arteries

    Pulmonary blood flow distribution was studied by scintillation scanning of the lungs after the infusion of iodine-131-labeled macroaggregates of human albumin before and after the Mustard operation in 53 patients with transposition of the great arteries. The patients were classified as follows: Group 1 (24 infants with uncomplicated transposition of the great arteries); Group II (18 patients with transposition and ventricular septal defect); and Group III (11 patients with transposition, ventricular septal defect and pulmonary obstruction). Before operation, 21 patients had a normal distribution of pulmonary blood flow, 10 had preferential flow to the right lung and 2 had preferential flow to the left lung. After operation, 19 had a normal pattern of pulmonary blood flow, 21 had preferential flow to the right lung and 3 had preferential flow to the left lung. The scanning studies have proved helpful in follow-up of patients to rule out recurrence of the shunt, pulmonary or systemic venous obstruction, development of pulmonary hypertension and occlusion of a palliative systemic-pulmonary shunt

    Full Text Available The objectives of this survey were to determine the effect of temperature on germination and seedling growth of Hyssop (Hyssopus officinalis L., Sweet basil (Ocimum basilicum L. and Oregano (Origanum vulgare L. (Lamiaceae family as well as comparing species regarding germination behavior and growth characteristics. Seeds were germinated on a temperature-gradient bar varying between 5 and 40 °C (with 5 °C intervals. Results indicated that the highest germination percentage of hyssop (92-98%, sweet basil (86-90% and oregano (74-77% occurred at 20-30 °C, 25-30 °C and 20-30 °C, respectively; therefore, moderate and warm temperatures are proper for germination of all species. In all species the maximum germination rate obtained at 30 °C. Among all species, Day 10 % of Sweet basil Germination had the lowest value, which indicates faster germination. The cardinal temperatures (base, optimum and ceiling or maximum were estimated by the segmented model. Base temperature (Tb was calculated for hyssop, sweet basil and oregano as 3.42, 5.70 and 5.46 °C, respectively. Optimal temperature (To calculated for all species was approximately 30°C, So warmer temperatures are much more proper for them. The species showed different maximum temperatures (Tm from 42.91 (Oregano to 48.05 °C (Hyssop. In Hyssop and Sweet basil optimum growth of seedlings were observed at 30°C while Oregano reached its best growth at 25°C. The difference between maximum and minimum temperatures of germination knowing as temperature range (TR index could show adaptation capability to broad sites for planting and domestication. Regarding this index Hyssop stood in the first place.

  8. Microbiological Status and Food Safety Compliance of Commercial Basil Production Systems.

    2016-01-01

    Basil has been implicated in a number of microbe-associated foodborne illnesses across the world, and the source of contamination has often been traced back to the production and/or processing stages of the supply chain. The aim of this study was to evaluate the microbiological quality of fresh basil from the point of production to the retail outlet in the Gauteng and Northwest Provinces of South Africa. A total of 463 samples were collected over a 3-month period from two large-scale commercial herb producing and processing companies and three retail outlets. The microbiological quality of the samples was assessed based on the presence or absence of Escherichia coli O157:H7 and Salmonella Typhimurium and the levels of the indicator bacteria E. coli and total coliforms. Salmonella Typhimurium was detected on four basil samples (0.9%) arriving at the processing facility and at dispatch, but no E. coli O157:H7 was detected throughout the study. Total coliform counts were 0.4 to 4.1 CFU/g for basil, 1.9 to 3.4 log CFU/ml for water, and 0.2 to 1.7 log CFU/cm(2) for contact surfaces, whereas E. coli was detected in the water samples and only once on basil. The Colilert-18 and membrane filter methods were used to analyze water samples, and a comparison of results revealed that the Colilert-18 method was more sensitive. Strong evidence suggests that high numbers of coliforms do not necessarily indicate the presence of Salmonella Typhimurium. The study results highlight the importance of effective implementation of food safety management systems in the fresh produce industry. PMID:26735028

For the last two decades radiofrequency catheter ablation (RFCA in pediatric patients has been dramatically advanced. Due to this progress the complication rate has been decreased and success rate has been improved. In cases, when arrhythmia can’t be controlled with drugs and becomes life-threatening (takes incessant character, sings of heart failure develop RFCA is considered to be the method of choice. The most common cause of tachyarrhythmias in children is an accessory pathway (AP. Elimination of AP at an early age can be technically challenging due to small body surface area, limitation of invasion and proved high rate of complications if a patient weighs less than 15 kgs. There are no published data on the long-term effects of RFCA on coronary arteries and myocardial function. Although animal studies showed RF lesion can expand with time and may affect coronary perfusion. A combination of congenital heart disease and incessant tachyarrhythmia is even more difficult to treat. In this article we present a case report of successful RFCA of AP in 4-months-old patient with corrected transposition of great arteries, Ebstein's like modification of tricuspid «arterial» valve, heart failure NYHA II and intraoperatively revealed thrombosis of femoral veins.

    1979-08-01

    Seven infants weighing from 6.4 to 10.3 kg underwent correction of transposition of the great arteries by the venous transposition operation as described by Shumacker. In this operation, a new atrial septum is constructed using a bipedicled right atrial flap, and the lateral atrial wall is constructed using a viable pericardial flap. Three of the patients had an associated ventricular septal defect. Six of the seven patients survived and have had an excellent clinical result. Although atrial arrhythmias were common in the early postoperative period, all patients are now in sinus rhythm. Two patients have had postoperative cardiac catheterization and cineangiography, which showed excellent hemodynamic results. The modified Shumacker operation preserves two of the three internodal pathways, provides a compliant, viable atrial septum, and permits fabrication of a generous-size physiological left atrium. This appears to offer advantages not present in the Mustard procedure. PMID:445766

    2015-03-01

    Full Text Available High prevalence and insufficient efficacy of medical treatment in type 2 diabetes mellitus (T2DM poses a major challenge for medical care. Generally, only 30% of patients reach therapeutic goals, while remission occurs only in the minority of patients. In the obese (BMI>35 kg/m2, bariatric surgery provides an alternative to pharmacological treatment of T2DM, boosting remission/compensation rate up to 76.8%. A few recent clinical studies explored the anti-diabetic effect of ileal transposition (IT. This type of surgery targets restoration of incretin balance by proximal transposition of ileal segment. In this review, we discuss the salutary mechanisms of IT in T2DM based on the analysis of the pioneering clinical trials.

    2007-01-01

    Single nucleotide polymorphisms (SNPs) represent a valuable resource for the mapping of human disease genes and induced mutations in model organisms. SNPs may become the markers of choice also for population ecology and evolutionary studies, but their isolation for non-model organisms with unsequenced genomes is often difficult. Here, we describe a rapid and cost-effective strategy to isolate SNPs that exploits the property of the bacteriophage Mu transposition machinery to target mismatched DNA sites and thereby to effectively detect polymorphic loci. To demonstrate the methodology, we isolated 164 SNPs from the unsequenced genome of the Glanville fritillary butterfly (Melitaea cinxia), a much-studied species in population biology, and we validated 24 of them. The strategy involves standard molecular biology techniques as well as undemanding MuA transposase-catalyzed in vitro transposition reactions, and it is applicable to any organism. PMID:17311815

    Transposition of great arteries (TGA) is one of the most common and severe congenital heart diseases (CHD). It is also one of the most mysterious CHD because it has no precedent in phylogenetic and ontogenetic development, it does not represent an alternative physiological model of blood circulation and its etiology and morphogenesis are still largely unknown. However, recent epidemiologic, experimental, and genetic data suggest new insights into the pathogenesis. TGA is very rarely associate...

  18. Pelvic Vein Embolisation in the Management of Varicose Veins

    Pelvic vein incompetence is common in patients with atypical varicose veins, contributing to their recurrence after surgery. Therefore, refluxing pelvic veins should be identified and treated. We present our experience with pelvic vein embolisation in patients presenting with varicose veins. Patients presenting with varicose veins with a duplex-proven contribution from perivulval veins undergo transvaginal duplex sonography (TVUS) to identify refluxing pelvic veins. Those with positive scans undergo embolisation before surgical treatment of their lower limb varicose veins. A total of 218 women (mean age of 46.3 years) were treated. Parity was documented in the first 60 patients, of whom 47 (78.3%) were multiparous, 11 (18.3%) had had one previous pregnancy, and 2 (3.3%) were nulliparous. The left ovarian vein was embolised in 78%, the right internal iliac in 64.7%, the left internal iliac in 56.4%, and the right ovarian vein in 42.2% of patients. At follow-up TVUS, mild reflux only was seen in 16, marked persistent reflux in 6, and new reflux in 3 patients. These 9 women underwent successful repeat embolisation. Two patients experienced pulmonary embolisation of the coils, of whom 1 was asymptomatic and 1 was successfully retrieved; 1 patient had a misplaced coil protruding into the common femoral vein; and 1 patient had perineal thrombophlebitis. The results of our study showed that pelvic venous embolisation by way of a transjugular approach is a safe and effective technique in the treatment of pelvic vein reflux.

  20. Daytime Solar Heating Controls Downy Mildew Peronospora belbahrii in Sweet Basil

    Cohen, Yigal; Rubin, Avia E.

    2015-01-01

    The biotrophic oomycete Peronospora belbahrii causes a devastating downy mildew disease in sweet basil. Due to the lack of resistant cultivars current control measures rely heavily on fungicides. However, resistance to fungicides and strict regulation on their deployment greatly restrict their use. Here we report on a ‘green’ method to control this disease. Growth chamber studies showed that P. belbahrii could hardly withstand exposure to high temperatures; exposure of spores, infected leaves...

  1. Efficacy of wash solutions in recovering Cyclospora cayetanensis, Cryptosporidium parvum, and Toxoplasma gondii from basil.

    Chandra, Venessa; Torres, Maria; Ortega, Ynés R

    2014-08-01

    Parasitic diseases can be acquired by ingestion of contaminated raw or minimally processed fresh produce (herbs and fruits). The sensitivity of methods used to detect parasites on fresh produce depends in part on the efficacy of wash solutions in removing them from suspect samples. In this study, six wash solutions (sterile E-Pure water, 3% levulinic acid-3% sodium dodecyl sulfate, 1 M glycine, 0.1 M phosphate-buffered saline, 0.1% Alconox, and 1% HCl-pepsin) were evaluated for their effectiveness in removing Cyclospora cayetanensis, Cryptosporidium parvum, and Toxoplasma gondii from basil. One hundred or 1,000 oocysts of these parasites were inoculated onto the adaxial surfaces of 25 g of basil leaves, placed in stomacher bags, and stored for 1 h at 21°C or 24 h at 4°C. Leaves were hand washed in each wash solution for 1 min. DNA was extracted from the wash solutions and amplified using PCR for the detection of all parasites. Oocysts inoculated at a concentration of 1,000 oocysts per 25 g of basil were detected in all wash solutions. At an inoculum concentration of 100 oocysts per 25 g, oocysts were detected in 18.5 to 92.6% of the wash solutions. The lowest variability in recovering oocysts from basil inoculated with 100 oocysts was observed in 1% HCl-pepsin wash solution. Oocyst recovery rates were higher at 1 h than at 24 h postinoculation. Unlike most bacteria, parasites cannot be enriched; therefore, an optimal recovery process for oocysts from suspected foods is critical. The observations in this study provide guidance concerning the selection of wash solutions giving the highest retrieval of parasite oocysts. PMID:25198596

  5. Performance Analysis of Transposition Models Simulating Solar Radiation on Inclined Surfaces

    Xie, Yu; Sengupta, Manajit

    2016-06-02

    Transposition models have been widely used in the solar energy industry to simulate solar radiation on inclined photovoltaic panels. Following numerous studies comparing the performance of transposition models, this work aims to understand the quantitative uncertainty in state-of-the-art transposition models and the sources leading to the uncertainty. Our results show significant differences between two highly used isotropic transposition models, with one substantially underestimating the diffuse plane-of-array irradiances when diffuse radiation is perfectly isotropic. In the empirical transposition models, the selection of the empirical coefficients and land surface albedo can both result in uncertainty in the output. This study can be used as a guide for the future development of physics-based transposition models and evaluations of system performance.

    The volatile profile of three sweet basil cultivars, "Italico a foglia larga", "Cammeo" and "Italiano classico", packaged in air at 4 or 12°C until 9days, was monitored by solid phase microextraction with GC-MS. Chilling injury (CI) score and electrolyte leakage were also assessed. In total, 71 volatile organic compounds (VOCs) were identified in the headspace of basil samples. A preliminary principal component analysis highlighted the dominant effect of the cultivar on VOCs profiles. Data analysis by post-transformation of projection to latent structures regression (ptPLS2) clarified the role played by time and temperature of storage. Temperature influenced the emission of volatiles during storage, with much lower total volatile emissions at 4°C compared to 12°C. Finally, a ptPLS2 regression model performed on VOCs and the two CI parameters allowed selection of 10 metabolites inversely correlated to both CI parameters, which can be considered potential markers of CI in basil leaves.

  7. Different species of basil need different ammonium to nitrate ratio in hydroponics' system

    M. SAADATIAN

    2015-12-01

    Full Text Available Basil is a very important medicinal plant and culinary spice, and is marketed fresh, dried or frozen. In crop nutrition, nitrogen is essential for plant growth and as a macro-element, is part of the proteins’ structure and participates in the metabolic processes involved in the synthesis and energy transfer. It has been shown that a balance between ammonium and nitrate favors plant growth and that the degree of benefit varies among crops. This study was conducted to evaluate the growth of two varieties of basil in function of four nutrient solutions containing different NH4+/NO3- ratios. Results showed that different variety response differently to nutrient solution. Although the highest yield in both varieties (sweet and purple was obtained when fed by nutrient solution without ammonium but their response on quality indices were different due to nitrate ammonium ratio in nutrient solutions. The highest total phenol content of sweet and purple basil was 92 and 100 mg gallic acid equivalent per gram of dry weight respectively, while the highest antioxidant capacity was obtained in purple variety grown in nutrient solution 2 (NH4+:1/NO3:4 and the lowest value were related to sweet variety with the same nutrient solution. Moderate content of total nitrogen can be suitable for sweet variety while for purple variety nutrient solution with low amount of ammonium can be more suitable.

  8. Higher Potassium Concentration in Shoots Reduces Gray Mold in Sweet Basil.

    2015-08-01

    Nutritional elements can affect plant susceptibility to plant pathogens, including Botrytis cinerea. We tested the effect of potassium (K) fertilization on gray mold in sweet basil grown in pots, containers, and soil. Increased K in the irrigation water and in the sweet basil tissue resulted in an exponential decrease in gray mold severity. Potassium supplied to plants by foliar application resulted in a significant decrease in gray mold in plants grown with a low rate of K fertigation. Lower K fertigation resulted in a significant increase in B. cinerea infection under semi-commercial conditions. Gray mold severity in harvested shoots was significantly negatively correlated with K concentration in the irrigation solution, revealing resistance to B. cinerea infection as a result of high K concentration in sweet basil tissue. Gray mold was reduced following K foliar application of the plants. In general, there was no synergy between the fertigation and foliar spray treatments. Proper K fertilization can replace some of the required chemical fungicide treatments and it may be integrated into gray mold management for improved disease suppression. PMID:25760521

  11. Neuroanatomical correlates of musical transposition in adolescents: A longitudinal approach

    Mary Elizabeth Sutherland

    2013-12-01

    Full Text Available Musicians are trained in melodic transposition, the skill of extracting the pitch interval structure and moving it into different keys. This ability to recognize whether a melody is the same or altered when it is played back in a different key is correlated with both greater neural activation and cortical thickness in bilateral intraparietal sulcus (IPS. Musical training only explains part of this finding, suggesting that the ability to transpose a melody may have innate predispositions. The current study was designed to address this question: Are the anatomical correlates of musical transposition already present in non-musician children at age 14.5? If so, is there any evidence that those traits were already in place at earlier ages? To answer this question, we recruited 47 adolescents (age 14.5 years from a longitudinal study and tested them on a melodic transposition task. These adolescents had already undergone anatomical MRI imaging at the ages of 10, 11.5, 13, and 14.5 years. They were tested on the transposition task at age 14.5. During this visit, we found a relationship between cortical thickness in left IPS and performance on the transposed melody task in the girls and not the boys; no such relationship was observed at any of the earlier ages. Girls reach more advanced staged of pubertal maturation earlier than boys, it is possible that the relationship between cortical thickness in IPS and skill at melodic transposition only emerges once the brain has reached a certain degree of maturity. This claim is supported by a lack of similar sex differences in the adults: the degree of correlation between cortical thickness and performance on the same transposed melody task did not differ between men and women in a previous study. Thus, our results suggest that the relationship between cortical thickness and the ability to transpose a melody is not fixed, and that the effects observed in adults are neither due exclusively to training nor to

  12. Fumigant Toxicity of Essential Oils from Basil and Spearmint Against Two Major Pyralid Pests of Stored Products.

    2015-04-01

    The fumigant activity of essential oil vapors distilled from sweet basil Ocimum basilicum L. and spearmint Mentha spicata L. (Lamiaceae) were tested against two major stored products pests Ephestia kuehniella (Zeller) and Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae). Various oil doses (0.5, 2.5, 5, 50, 250, 500, 1,000, and 1,500 µl/liter air), for an exposure period of 24 h, were tested. The essential oils were subjected to gas chromatography-mass spectrometry analysis and revealed that the major compounds were for spearmint oil carvone (67.1%) and limonene (+1,8 cineole; 14.3%) and for basil oil linalool (45.9%), 1,8 cineole (16.7%) and eugenol (10.3%). Apart from a few exceptions, no significant differences in insecticidal action were observed between basil and spearmint oil. Both oils were highly effective against adult moths, given that notable mortality (>80%) was recorded after exposure to low doses such as 2.5 µl/liter. Noteworthy, egg mortality was also recorded, reaching 73-79% for basil and 56-60% for spearmint. Toxicity data indicated that larvae and pupae were the most tolerant stages in all cases. Larval mortality never exceeded 21 and 18%, for basil and spearmint, respectively, irrespective of moth species. Basil and spearmint oils displayed mortalities as high as 38 and 28% in pupae. Lethal doses (LD50 and LD99) values were estimated via probit analysis. Developmental stage proved to be a significant factor, whereas the effect of oil species on insect mortality was insignificant. With the exception of adult individuals, basil and spearmint oils did not show satisfactory overall insecticidal activity against E. kuehniella and P. interpunctella. PMID:26470193

  20. Performance Analysis of Transposition Models Simulating Solar Radiation on Inclined Surfaces: Preprint

    Xie, Yu; Sengupta, Manajit

    2016-06-01

    Transposition models are widely used in the solar energy industry to simulate solar radiation on inclined photovoltaic (PV) panels. These transposition models have been developed using various assumptions about the distribution of the diffuse radiation, and most of the parameterizations in these models have been developed using hourly ground data sets. Numerous studies have compared the performance of transposition models, but this paper aims to understand the quantitative uncertainty in the state-of-the-art transposition models and the sources leading to the uncertainty using high-resolution ground measurements in the plane of array. Our results suggest that the amount of aerosol optical depth can affect the accuracy of isotropic models. The choice of empirical coefficients and the use of decomposition models can both result in uncertainty in the output from the transposition models. It is expected that the results of this study will ultimately lead to improvements of the parameterizations as well as the development of improved physical models.

  1. Epidermal coumaroyl anthocyanins protect sweet basil against excess light stress: multiple consequences of light attenuation.

    Tattini, Massimiliano; Landi, Marco; Brunetti, Cecilia; Giordano, Cristiana; Remorini, Damiano; Gould, Kevin S; Guidi, Lucia

    2014-11-01

    The putative photoprotective role of foliar anthocyanins continues to attract heated debate. Strikingly different experimental set-ups coupled with a poor knowledge of anthocyanin identity have likely contributed to such disparate opinions. Here, the photosynthetic responses to 30 or 100% solar irradiance were compared in two cultivars of basil, the green-leafed Tigullio (TG) and the purple-leafed Red Rubin (RR). Coumaroyl anthocyanins in RR leaf epidermis significantly mitigated the effects of high light stress. In full sunlight, RR leaves displayed several shade-plant traits; they transferred less energy than did TG to photosystem II (PSII), and non-photochemical quenching was lower. The higher xanthophyll cycle activity in TG was insufficient to prevent inactivation of PSII in full sunlight. However, TG was the more efficient in the shade; RR was far less able to accommodate a large change in irradiance. Investment of carbon to phenylpropanoid biosynthesis was more in RR than in TG in the shade, and was either greatly enhanced in TG or varied little in RR because of high sunlight. The metabolic cost of photoprotection was lower whereas light-induced increase in biomass production was higher in RR than in TG, thus making purple basil the more light tolerant. Purple basil appears indeed to display the conservative resource-use strategy usually observed in highly stress tolerant species. We conclude that the presence of epidermal coumaroyl anthocyanins confers protective benefits under high light, but it is associated with a reduced plasticity to accommodate changing light fluxes as compared with green leaves.

    Full Text Available Aim:The objective of this study is to investigate the hypoglycemic, hypolipidemic, and hepatoprotective effects of the aqueous extract of parsley, basil, and chicory whole plant in normal and dexamethasone (Dex rats. Materials and Methods: 50 female albino rats were used in this study and divided into 5 groups (for each 10. Group (1 fed basal diet and maintained as negative control group. Group (2 received Dex in a dose of (0.1 mg/kg b. wt.. Groups 3, 4, and 5 were treated with Dex along with three different plant extracts of parsley, basil, and chicory (2 g/kg b. wt., (400 mg/kg b. wt., and (100 mg/kg b. wt., respectively. Results: All these groups were treated given three times per week for 8 consecutive weeks. Dex-induced alterations in the levels of serum glucose, triglyceride, cholesterol, low-density lipoprotein-cholesterol levels and cardiovascular indices and serum alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities, liver thiobarbituric acid (TBARS levels increased, while high-density lipoprotein-cholesterol, total protein, albumin, and liver glutathione (GSH levels decreased. On the other hand, plant extracts succeeded to modulate these observed abnormalities resulting from Dex as indicated by the reduction of glucose, cholesterol, TBARS, and the pronounced improvement of the investigated biochemical and antioxidant parameters. Conclusions: It was concluded that probably, due to its antioxidant property, parsley, basil, and chicory extracts have hepatoprotective effects in Dex-induced in rats.

    Sweet basil (Ocimum basilicum), one of the most popular cultivated herbs worldwide, displays a number of varieties differing in several characteristics, such as the color of the leaves. The development of a reference transcriptome for sweet basil, and the analysis of differentially expressed genes in acyanic and cyanic cultivars exposed to natural sunlight irradiance, has interest from horticultural and biological point of views. There is still great uncertainty about the significance of anthocyanins in photoprotection, and how green and red morphs may perform when exposed to photo-inhibitory light, a condition plants face on daily and seasonal basis. We sequenced the leaf transcriptome of the green-leaved Tigullio (TIG) and the purple-leaved Red Rubin (RR) exposed to full sunlight over a four-week experimental period. We assembled and annotated 111,007 transcripts. A total of 5,468 and 5,969 potential SSRs were identified in TIG and RR, respectively, out of which 66 were polymorphic in silico. Comparative analysis of the two transcriptomes showed 2,372 differentially expressed genes (DEGs) clustered in 222 enriched Gene ontology terms. Green and red basil mostly differed for transcripts abundance of genes involved in secondary metabolism. While the biosynthesis of waxes was up-regulated in red basil, the biosynthesis of flavonols and carotenoids was up-regulated in green basil. Data from our study provides a comprehensive transcriptome survey, gene sequence resources and microsatellites that can be used for further investigations in sweet basil. The analysis of DEGs and their functional classification also offers new insights on the functional role of anthocyanins in photoprotection. PMID:27483170

    Full Text Available Problem statement: Certain basil essential oils were claimed to have a larvicidal activity towards mosquito's larvae. To test this claim the essential oils of four accessions of basil grown in Sudan were selected and tested for Anopheles larvae. Malaria is the major health problem in the Sudan and the whole country is now considered endemic, with varying degrees, about 35,000 deaths every year due to malaria. Anopheles mosquito is the major vector of malaria disease in Sudan. Search for larvicidal active compound(s is one of several attempts to fine effective and affordable ways to control this mosquito. To determine the toxic effects of basil essential oils extracted by steam distillation against Anopheles larvae. Approach: For the larvicidal bioassay, three concentrations (100, 300, 500 ppm of essential oil solutions of four basil accessions were prepared; 1 mL of ethanol was used to solubilize the oil in water (999 mL. In each concentration of oil solution were inserted 20 larvae (third instars. A set of controls using 0.1% ethanol and untreated sets of larvae in (tap water, were also run for comparison. Data were evaluated through regression analysis, from the regression line; the LC50 values were read. The active ingredients were separated and/ or identified by TLC, IR and GC-MS. Results: Larvicidal activity of the essential oils is varied, lasted for about 9 h and thereafter decreased, LC50 values ranging from 190-300 ppm. Linalool, geraniol and eugenol are active components of basil essential oil against Anopheles larvae. Two accessions were caused 100% mortality at a concentration range 300-500 ppm for 3 h. Conclusion: These results indicated that basil essential oils have larvicidal activity towards Anopheles larvae. Therefore, could be affordable way to control this mosquito.

    Dushyant Jaiswal

    2015-01-01

    Full Text Available Introduction: Tracheoesophageal voice prosthesis is highly effective in providing speech after total laryngectomy. Although it is a safe method, in certain cases dilatation or leakage occurs around the prosthesis that needs closure of tracheoesophageal fistula. Both non-surgical and surgical methods for closure have been described. Surgical methods are used when non-surgical methods fail. We present the use of the sternocleidomastoid musculocutaneous (SCMMC transposition flap for the closure of tracheoesophageal fistula. Materials and Methods: An incision is made at the mucocutaneous junction circumferentially around the tracheostoma. Tracheoesophageal space is dissected down to and beyond the fistula. The tracheoesophageal tract is divided. The oesophageal mucosa is closed with simple sutures. Then SCMMC transposition flap is raised and transposed to cover sutured oesophagus and the defect between the oesophagus and the trachea. Results: This study was done prospectively over a period of 1 year from June 2012 to May 2013. This technique was used in patients with pliable neck skin. In nine patients, this procedure was done (inferior based flap in nine cases and it was successful in eight patients. In one case, there was dehiscence at the leading edge of flap with oesophageal dehiscence, which required a second procedure. In two cases, there was marginal necrosis of flap, which healed without any intervention. Nine patients in this series were post-radiation. Conclusion: This method of closure is simple and effective for patients with pliable neck skin, who require permanent closure of the tracheoesophageal fistula.

    2010-06-01

    Full Text Available Sweet basil (Ocimum basilicum is a popular culinary herbal crop grown for fresh or dry leaf, essential oil and seed markets. Recently, basil was shown to rank highest among species and herbal crops for phenolic compounds, essential oils which are associated with decreasing risks of cancer and aging diseases. The current study aimed to evaluate the potential activity of phenolic, flavonoids and essential oil of basil as antioxidant and anticancer activities by application organic and bio-organic fertilization. A pot experiment was conducted. Basil seeds were grown, with three levels of organic fertilizers (compost in presence or absence of biofertilizer. Growth parameters, pigments content, total phenolics, total flavonoids and antioxidant activity of methanolic plant extract were examined. Application of 50% compost and 50% sand in the presence of biofertilizer resulted in enhancement fresh and dry weights, total phenolics, total flavonoids and pigment content as compared with compost alone. The constituents of essential oils extracted by hydrodistilation of basil leaves were identified by GLC. Eleven components of essential oils were identified. The highest value of antioxidant and anticancer activities were obtained in basil plants grown in 50% and 75% compost treatments in the presence of biofertilizer. These results emphasized the important of bioorganic fertilizers for enhancement the antioxidant activity of phenolics, flavonoids, and essential oils of basil plant extract.

    2015-08-01

    Full Text Available Effects of the probiotic ‘Protexin', basil essential oil and the antibiotic growth promoter ‘Avilamycin' were studied on the ileum microbial flora of broilers when these substances are used as broiler feed additives. A total of six hundred Arian broilers were divided into 6 treatment groups, with 4 replicates of 25 birds. Treatments have been performed with a plant essential oil at 3 levels (200, 400 and 600 ppm, the probiotic ‘Protexin' (150 ppm, the antibiotic ‘Avilamycin' (150 ppm and a control group with no additives. Birds in different treatments received the same diets during the experimental period. The results showed that the probiotic treatment significantly decreased the total bacteria counts (P0.05. The lowest and highest lactic acid bacteria in ileum were obtained in the control group and in birds receiving 400 ppm basil essential oil, respectively. Moreover, addition of 600 ppm of basil essential oil into diet decreased the number of E. coli colonies as compared to other treatments (P< 0.05. It could be speculated that the basil essential oil and ‘Protexin' could replace the antibiotics, which have been banned to use as growth promoter in animal feeds.

    Full Text Available The relations between the churches of Elder and New Rome during the reign of Basil II and the enthronement of Alexios StοuditesThis study investigates the relations between the churches of Elder and New Rome during the reign of Basil II and concludes that the attempts to impose Boniface VII in 984/985 and John XVI in 997/998 as popes of Rome and the long controversy between the two sides (1011-1024 was against the policy of the Macedonian dynasty and also threatened Byzantine rule in Southern Italy. Near the time of his death, Basil II assigned the continuation of the reconciliation policy with the Roman Church (accomplished in 1024/1025 to the patriarch Alexios and to the long lasting tradition of the monastery of Stoudios. The warm welcome given by Alexios to abbot Richard of Saint-Vanne, advocate of the rising power and role of the pope of Rome, reveals a deeper reason which dictated to Basil II the choice of a Stoudite for the patriarchal see of Constantinople.

  13. Transposition of the gas directive in French law

    On September 25, 2002, the French government adopted the project of law relative to the energy markets. This project of law takes up the essential part of the measures proposed by the directive no 98/30/CE of the European Union from June 22, 1998, about the 'common rules of the internal natural gas market'. This paper makes a brief comment of the version of this project adopted by the senate. It presents also the position of the French gas association (AFG) about this transposition, its action during the first phase of the parliamentary debate, and what will be AFG's role after the enforcement of this law. Finally, a testimony of the Swiss society of gas and waters industry (SSIGE) about the opening of the natural gas market is given in conclusion. (J.S.)

  14. Inactivation of a transgene due to transposition of insertion sequence (IS136) of Agrobacterium tumefaciens

    Preeti Rawat; Sanjeev Kumar; Deepak Pental; Pradeep Kumar Burma

    2009-06-01

    Agrobacterium strains harbour insertion sequences, which are known to transpose into genomes as well as into Ti plasmids. In this study we report the inactivation of a transgene due to transposition of the A. tumefaciens insertion sequence IS136. The transposition was discovered following transformation of plant tissues, although the fidelity of the binary vector was confirmed following transformation into Agrobacterium. Such transpositions are rare but can occur and it is thus important to check the fidelity of the binary vector at different times of Agrobacterium growth in order to avoid failure in achieving transgene expression.

  15. TRANSPOSITION OF GREAT ARTERIES: NEW INSIGHTS INTO THE PATHOGENESIS

    Marta eUnolt

    2013-06-01

    Full Text Available Transposition of great arteries (TGA is one of the most common and severe congenital heart diseases (CHD. It is also one of the most mysterious CHD because it has no precedent in phylogenetic and ontogenetic development, it does not represent an alternative physiological model of blood circulation and its etiology and morphogenesis are still largely unknown. However, recent epidemiologic, experimental and genetic data suggest new insights into the pathogenesis. TGA is very rarely associated with the most frequent genetic syndromes, such as Turner, Noonan, Williams or Marfan syndromes, and in Down syndrome, it is virtually absent. The only genetic syndrome with a strong relation with TGA is Heterotaxy. Moreover, TGA is rather frequent in cases of isolated dextrocardia with situs solitus, showing link with defect of visceral situs. In lateralization defects TGA is frequently associated with asplenia syndrome. Nowadays, the most reliable method to induce TGA consists in treating pregnant mice with retinoic acid or with retinoic acid inhibitors. Following such treatment not only cases of TGA with d-ventricular loop have been registered, but also some cases of congenitally corrected transposition of great arteries (CCTGA. In another experiment, the embryos of mice treated with retinoic acid in day 6.5 presented Heterotaxy, suggesting a relationship among these morphologically different CHD. In some families, beside TGA cases, there were first-degree relatives with CCTGA. This data suggest that monogenic inheritance with a variable phenotypic expression could explain the familial aggregation of TGA and CCTGA. In some of these families we previously found multiple mutations in laterality genes including Nodal and ZIC3, confirming a pathogenetic relation between TGA and Heterotaxy. These overall data suggest to include TGA in the pathogenetic group of laterality defects instead of conotruncal abnormalities due to ectomesenchymal tissue migration.

  16. Increased Ac excision (iae): Arabidopsis thaliana mutations affecting Ac transposition

    The maize transposable element Ac is highly active in the heterologous hosts tobacco and tomato, but shows very much reduced levels of activity in Arabidopsis. A mutagenesis experiment was undertaken with the aim of identifying Arabidopsis host factors responsible for the observed low levels of Ac activity. Seed from a line carrying a single copy of the Ac element inserted into the streptomycin phosphotransferase (SPT) reporter fusion, and which displayed typically low levels of Ac activity, were mutagenized using gamma rays. Nineteen mutants displaying high levels of somatic Ac activity, as judged by their highly variegated phenotypes, were isolated after screening the M2 generation on streptomycin-containing medium. The mutations fall into two complementation groups, iae1 and iae2, are unlinked to the SPT::Ac locus and segregate in a Mendelian fashion. The iae1 mutation is recessive and the iae2 mutation is semi-dominant. The iae1 and iae2 mutants show 550- and 70-fold increases, respectively, in the average number of Ac excision sectors per cotyledon. The IAE1 locus maps to chromosome 2, whereas the SPT::Ac reporter maps to chromosome 3. A molecular study of Ac activity in the iae1 mutant confirmed the very high levels of Ac excision predicted using the phenotypic assay, but revealed only low levels of Ac re-insertion. Analyses of germinal transposition in the iae1 mutant demonstrated an average germinal excision frequency of 3% and a frequency of independent Ac re-insertions following germinal excision of 22%. The iae mutants represents a possible means of improving the efficiency of Ac/Ds transposon tagging systems in Arabidopsis, and will enable the dissection of host involvement in Ac transposition and the mechanisms employed for controlling transposable element activity

  18. Vein type uranium deposits

    Veins are tabular- or sheet-like masses of minerals occupying or following a fracture or a set of fractures in the enclosing rock. They have been formed later than the country rock and fractures, either by filling of the open spaces or by partial or complete replacement of the adjoining rock or most commonly by both of these processes combined. This volume begins with the occurrences and deposits known from old shield areas and the sedimentary belts surrounding them. They are followed by papers describing the European deposits mostly of Variscan age, and by similar deposits known from China being of Jurassic age. The volume is completed by two papers which do not fit exactly in the given scheme. A separate abstract was prepared for each of the 25 papers in this report

  19. Maxillary canine-first premolar transposition in the permanent dentition: treatment considerations and a case report.

    Synodinos, Philippos N

    2010-12-01

    Transposition is defined as the interchange of position between two adjacent teeth within the same quadrant of the dental arch. Permanent maxillary canine-premolar transposition is the most commonly observed transposition in the human dentition. Its prevalence is relatively low and its aetiology remains unclear, although it has been associated with genetic factors. It may also be related to a combination of localised factors such as malformation of adjacent teeth, tooth agenesis, retention of the deciduous canine and a history of local trauma. Treatment is selected on an individual case basis after thoroughly considering the overall facial and dental characteristics, duration of treatment, cost, patient preference and the orthodontist\\'s experience. This article provides a case report of maxillary canine transposition in the permanent dentition, successfully managed with orthodontic treatment.

  20. Modified Shumacker operation for correction of transposition of the great arteries.

    Alvarado, A

    1977-10-01

    Correction of the transposition of the great arteries can be accomplished with a modified Shumacker operation. This procedure has been demonstrated in cadavers to have many advantages over the techniques used by Mustard and by Angelini and Sandiford. At present these two operations provide the best clinical results in correction of transposition of the great arteries. The details of the modified Shumacker technique are described and the different advantages of this technique are discussed. PMID:904361

  1. IS231A from Bacillus thuringiensis is functional in Escherichia coli: transposition and insertion specificity.

    Hallet, Bernard; Rezsohazy, René; Delcour, Jean

    1991-01-01

    A kanamycin resistance gene was introduced within the insertion sequence IS231A from Bacillus thuringiensis, and transposition of the element was demonstrated in Escherichia coli. DNA sequencing at the target sites showed that IS231A transposition results in direct repeats of variable lengths (10, 11, and 12 bp). These target sequences resemble the terminal inverted repeats of the transposon Tn4430, which are the preferred natural insertion sites of IS231 in B. thuringiensis.

    1992-12-01

    Ovarian transposition in adults has been shown to protect ovarian function in about 60% of cases by reducing ovarian exposure to less than 4 to 7 Gy. We therefore evaluated the effect of ovarian transposition during childhood or adolescence. Eighteen girls had ovarian transposition performed at a mean (+/- SEM) age of 9.4 +/- 1.2 years (range, 1.2 to 16 years). Twelve were prepubertal and six had menstruated at the time of ovarian transposition. The initial abnormalities were Hodgkin disease (5 cases), iliac Ewing sarcoma (3), medulloblastoma (2), ovarian seminoma (1), and vaginal or uterine tumor (7). The irradiation was external in 11 cases and local by vaginal curietherapy in 7 cases. Fifteen girls received chemotherapy. The ovarian transposition was bilateral in 15 patients and unilateral in 3 cases; in the latter the other ovary had been destroyed by the tumor or by abdominal irradiation. Ovaries were placed just below the iliac crest (15 cases) or posterolateral to the uterus (3); thus, the calculated ovarian radiation dose was up to 9.5 Gy. At the time of evaluation (8.6 +/- 0.9 years after ovarian transposition), 16 girls had menstruated and 2 remained amenorrheic because of major lesions of the vagina and uterus caused by the vaginal curietherapy. Basal plasma gonadotropin values were normal. Ovulation was documented in seven cases. Two pregnancies occurred. Complications of ovarian transposition were present in four patients: intestinal occlusion, dyspareunia, functional ovarian cysts, and pelvic adhesions with tubal obstruction. We conclude that ovarian transposition, performed before abdominopelvic irradiation during childhood, can preserve ovarian function. Longer follow-up is required to assess the risk of ovarian dystrophy because of vascular lesions or chemotherapy. PMID:1447649

    1987-01-01

    We have analyzed donor and target sites of the mobile element Activator (Ac) that are altered as a result of somatic transposition from the P locus in maize. Previous genetic analysis has indicated that the two mitotic daughter lineages which result from Ac transposition from P differ in their Ac constitution at the P locus. Both lineages, however, usually contain transposed Ac elements which map to the same genetic position. Using methylation-sensitive restriction enzymes and genomic blot a...

    2008-01-01

    DNA synthesis is considered a defining feature in the movement of transposable elements. In determining the mechanism of piggyBac transposition, an insect transposon that is being increasingly used for genome manipulation in a variety of systems including mammalian cells, we have found that DNA synthesis can be avoided during piggyBac transposition, both at the donor site following transposon excision and at the insertion site following transposon integration. We demonstrate that piggyBac tra...

  5. The time-dependent effect of conflict on delays in the transposition of EU directives

    Zhelyazkova, A.; Torenvlied, R.

    2009-01-01

    This article analyses the effect of conflict in the Council of the European Union (EU) on delays in the transposition of EU directives. Based on enforcement and management theories, we predict that conflict in the Council speeds up the transposition process. In addition, we control for the instigation of infringement procedures by the Commission and expect a weaker effect of conflict in cases where the Commission disagrees with a directive and if directives grant more discretion to member sta...

  6. Canine transposition in prehistoric Pakistan: Bronze Age and Iron Age case reports.

    Lukacs, J R

    1998-10-01

    This report documents two prehistoric cases of canine-first premolar transposition (Mx.C.P1) from the Indo-Pakistan subcontinent. Recent discussion of the etiology of canine transposition and reports of high prevalence for the condition in modern India accentuate the significance of the ancient cases reported there. Case 1 is from the Iron Age site of Sarai Khola in northern Pakistan (1000 BC). The specimen, an adult female, 25 to 30 years of age at death, exhibits unilateral Mx.C.P1 transposition on the left side. The condition is associated with a barrel-shaped maxillary left third molar in an otherwise normal and healthy maxillary dental arch. Case 2 is from the Bronze Age urban site of Harappa (2500 BC), an important center of the Indus Valley Civilization. In this specimen, an adult female, transposition is bilateral, resulting in displacement of premolars and large diastemata between the maxillary lateral incisors and first premolars. Bilateral agenesis of maxillary third molars and rotation of maxillary and mandibular teeth occur with transposition in this specimen. In neither case are the lateral incisors reduced in size, peg-shaped, or congenitally absent. This report of Mx.C.P1 transposition in prehistoric times is significant because it provides historical documentation for the female predilection of the trait and establishes its co-occurrence with specific dental variants, such as agenesis, reduction, and rotation of teeth.

  7. Effect of jasmonic acid elicitation on the yield, chemical composition, and antioxidant and anti-inflammatory properties of essential oil of lettuce leaf basil (Ocimum basilicum L.).

    Złotek, Urszula; Michalak-Majewska, Monika; Szymanowska, Urszula

    2016-12-15

    The effect of elicitation with jasmonic acid (JA) on the plant yield, the production and composition of essential oils of lettuce leaf basil was evaluated. JA-elicitation slightly affected the yield of plants and significantly increased the amount of essential oils produced by basil - the highest oil yield (0.78±0.005mL/100gdw) was achieved in plants elicited with 100μM JA. The application of the tested elicitor also influenced the chemical composition of basil essential oils - 100μM JA increased the linalool, eugenol, and limonene levels, while 1μM JA caused the highest increase in the methyl eugenol content. Essential oils from JA-elicited basil (especially 1μM and 100μM) exhibited more effective antioxidant and anti-inflammatory potential; therefore, this inducer may be a very useful biochemical tool for improving production and composition of herbal essential oils.

  8. Thrombosis of right ovarian vein

    Ovarian vein thrombosis is a rare postpartum complication (0.1%). It can be fatal, since it can lead to sepsis, pulmonary thromboembolisms and inferior vena cava or renal vein thrombosis. Computed tomography and magnetic resonance imaging are the techniques of choice for its diagnosis, while the value of ultrasound is limited due to its low sensitivity and specificity. We report the case of a woman who, during puerperium, developed thrombosis of right ovarian vein that presented clinical, ultrasonographic and computed tomographic features of appendicitis. We describe the radiological sings and stress the fact that this diagnosis should be suspected in puerperal women. (Author) 9 refs

  9. Surgical transposition of the ovaries: Imaging findings in 14 patients

    Pelvic radiation therapy for cervical or vaginal cancer often leads to ovarian failure. To remove the ovaries from the radiation portal and preserve their function, they can be transposed to the lateral abdomen. Serial imaging studies in 14 patients who had undergone ovarian transposition (five bilateral, nine unilateral) were reviewed. Images obtained included 32 CT scans, 20 sonograms, and one MR image. Most transposed ovaries were located along the paracolic gutters near the iliac crests, creating an extrinsic mass effect on adjacent bowel. Detection of surgical clips on the ovary on CT scans allowed confident recognition of all 19 transposed ovaries. Cysts in the transposed ovaries, noted on most imaging studies, did not correlate with complications of pain or hormonal dysfunction. In one case, a large physiologic cyst in a transposed ovary distorted the cecum and was mistaken for a mucocele of the appendix. In another case, a large ovarian cyst was thought to be tumor recurrence or a lymphocele. These findings indicate that although the transposed ovaries can be recognized on CT scans by the surgical clips attached to the ovaries, the appearance of the ovary does not predict reliably the development of complications

  10. Transposition of the EU cogeneration directive: A vision for Portugal

    The potential for new, small-scale and micro-cogeneration installations in Portugal is very considerable due to the number of potential host buildings. In this work, we discuss the legal framework of the Portuguese energy market, and some modifications to accommodate the Directive, 2004/8/EC are stressed. A practical case of cogeneration is also presented, showing the application of the Annex III (b) and (c) of the Cogeneration Directive. The practical case presented shows that micro CHP can be considered highly efficient, with parameters calculated with the Directive rules. Two main improvements in Portugal's energy policy are important: improvement on the permission to access grid system and improvement on support mechanisms indexing it to PES. The Cogeneration Directive transposition is an excellent opportunity to induce a less restrictive framework for the installation of new cogeneration systems, reducing the technological barriers, namely allowing medium-voltage connection with the grid, and improving the revenues provided from these small cogeneration systems. These modifications can improve significantly the number of potential hosts for small-scale cogeneration systems

  12. Analysis of a digital technique for frequency transposition of speech

    Digirolamo, V.

    1985-09-01

    Frequency transposition is the process of raising or lowering the frequency content (pitch) of an audio signal. The hearing impaired community has the greatest interest in the applications of frequency transposing. Though several analog and digital frequency transposing hearing aid systems have been built and tested, this thesis investigates a possible digital processing alternative. Pole shifting, in the z-domain, of an autoregressive (all pole) model of speech was proven to be a viable theory for changing frequency content. Since linear predictive coding (LPC) techniques are used to code, analyze and synthesize speech, with the resulting LPC coefficients related to the coefficients of an equivalent autoregressive model, a linear relationship between LPC coefficients and frequency tranposition is explored. This theoretical relationship is first established using a pure sine wave and then is extended into processing speech. The resulting speech synthesis experiments failed to substantiate the conjectures of this thesis. However, future research avenues are suggested that may lead toward a viable approach to transpose speech.

    Corrosion inhibition efficiencies of holy basil on Al in HCl solution were studied by weight loss and thermometric methods in presence and in absence of stem extract of three different varieties of holy basil viz. ocimum basilicum (E{sub B}), ocimum canum (E{sub C}) and ocimum sanctum (E{sub S}). Inhibition efficiency increases with the increasing concentration of stem extract and decreases with increases in acid strength. Results show that all varieties under study are good corrosion inhibitors, among which, E{sub B} is most effective. Maximum inhibition efficiency was found 97.09% in 0.5N HCl solution with 0.6% stem extract. The Langmuir adsorption isotherm indicates that surface coverage also increases with increasing in the concentration of extract of stem in HCl solution.

    Palm vein authentication is one of the modern biometric techniques, which employs the vein pattern in the human palm to verify the person. The merits of palm vein on classical biometric (e.g. fingerprint, iris, face) are a low risk of falsification, difficulty of duplicated and stability. In this research, a new method is proposed for personal verification based on palm vein features. In the propose method, the palm vein images are firstly enhanced and then the features are extracted by using...

In the internal part of the Italian type salami the commercial antioxidant (control and the formulation containing 0.75 mg.g-1 of basil essential oil presented antioxidant activity in relation to the lipids, but not to the proteins - during processing and storage.

  18. Base flipping in tn10 transposition: an active flip and capture mechanism.

    Julien Bischerour

    Full Text Available The bacterial Tn5 and Tn10 transposases have a single active site that cuts both strands of DNA at their respective transposon ends. This is achieved using a hairpin intermediate that requires the DNA to change conformation during the reaction. In Tn5 these changes are controlled in part by a flipped nucleoside that is stacked on a tryptophan residue in a hydrophobic pocket of the transposase. Here we have investigated the base flipping mechanism in Tn10 transposition. As in Tn5 transposition, we find that base flipping takes place after the first nick and is required for efficient hairpin formation and resolution. Experiments with an abasic substrate show that the role of base flipping in hairpin formation is to remove the base from the DNA helix. Specific interactions between the flipped base and the stacking tryptophan residue are required for hairpin resolution later in the reaction. We show that base flipping in Tn10 transposition is not a passive reaction in which a spontaneously flipped base is captured and retained by the protein. Rather, it is driven in part by a methionine probe residue that helps to force the flipped base from the base stack. Overall, it appears that base flipping in Tn10 transposition is similar to that in Tn5 transposition.

  19. Transposition bursts during analysis of secondary mutations in the unstable lines of Drosophila melanogaster

    The article deals with realization of transposition memory discovered earlier at cut locus and in MDG4. The unstable line cmMR17 ctMRpN17, a derivative of ctMR2 line, was used. It has high frequency of double cm+ct+ revertants and secondary cmMRctMRpN mutants. Such mutant transitions were observed in the line five times. Mutation ctMRpN17 was caused by the insertion at cut locus of MDG4 with another mobile element, jockey. In situ hybridization showed that the transitions from mutational condition to normal are strongly correlated with the excision of MDG4 and jockey from 7B3-4 region of cut locus and their repeated insertion into it. The analysis of distribution of MDG1, MDG2, MDG3, and jockey in the X chromosomes of the revertant larvae and secondary mutants showed that not only transpositions of MDG4 and jockey but also simultaneous multiple migration of all the tested mobile elements take place with their complete stability in the absence of mutational transitions. Therefore, the transposition memory in this system of genetic instability is realized in the process of transposition bursts, but does not lead to isolated repeated transpositions of MDG4

    2001-12-01

    Distribution of two structural functional variants of the MDG4 (gypsy) mobile genetic element was examined in 44 strains of Drosophila melanogaster. The results obtained suggest that less transpositionally active MDG4 variant is more ancient component of the Drosophila genome. Using Southern blotting, five strains characterized by increased copy number of MDG4 with significant prevalence of the active variant over the less active one were selected for further analysis. Genetic analysis of these strains led to the suggestion that some of them carry factors that mobilize MDG4 independently from the cellular flamenco gene known to be responsible for transposition of this element. Other strains probably contained a suppressor of the flam- mutant allele causing active transpositions of the MDG4. Thus, the material for studying poorly examined relationships between the retrovirus and the host cell genome was obtained. PMID:11785284

    2005-06-01

    Full Text Available Anterior transposition of the ulnar nerve is widely implemented for treatment of cubital tunnel ‎syndrome. However, preservation of the extrinsic blood supply of the ‎ulnar nerve may result in better clinical outcomes. Fourteen patients with cubital tunnel ‎syndrome, 11 ‎men and 3 women, were treated by anterior subcutaneous transposition of the ulnar nerve. The extrinsic blood supply of the ulnar nerve was ‎preserved. The average age at the time of operation was 33 years. The average follow-up period was 44 months. Post-operative outcome assessment by an independent examiner was based on the modified Bishop rating system. Nine patients had excellent or good outcomes. Five patients had a fair outcome. There ‎were no complications or recurrence of symptoms. Anterior subcutaneous ‎transposition of the vascularized ulnar nerve is an effective method of surgical ‎treatment for patients with cubital tunnel syndrome.

  3. cis and trans factors affecting Mos1 mariner evolution and transposition in vitro, and its potential for functional genomics.

    Tosi, L R; Beverley, S M

    2000-02-01

    Mos1 and other mariner / Tc1 transposons move horizon-tally during evolution, and when transplanted into heterologous species can transpose in organisms ranging from prokaryotes to protozoans and vertebrates. To further develop the Drosophila Mos1 mariner system as a genetic tool and to probe mechanisms affecting the regulation of transposition activity, we developed an in vitro system for Mos1 transposition using purified transposase and selectable Mos1 derivatives. Transposition frequencies of nearly 10(-3)/target DNA molecule were obtained, and insertions occurred at TA dinucleotides with little other sequence specificity. Mos1 elements containing only the 28 bp terminal inverted repeats were inactive in vitro, while elements containing a few additional internal bases were fully active, establishing the minimal cis -acting requirements for transposition. With increasing transposase the transposition frequency increased to a plateau value, in contrast to the predictions of the protein over-expression inhibition model and to that found recently with a reconstructed Himar1 transposase. This difference between the 'natural' Mos1 and 'reconstructed' Himar1 transposases suggests an evolutionary path for down-regulation of mariner transposition following its introduction into a naïve population. The establishment of the cis and trans requirements for optimal mariner transposition in vitro provides key data for the creation of vectors for in vitro mutagenesis, and will facilitate the development of in vivo systems for mariner transposition.

  4. Chloroplast DNA phylogeography of holy basil (Ocimum tenuiflorum) in Indian subcontinent.

    Bast, Felix; Rani, Pooja; Meena, Devendra

    2014-01-01

    Ocimum tenuiflorum L., holy basil "Tulsi", is an important medicinal plant that is being grown and traditionally revered throughout Indian Subcontinent for thousands of years; however, DNA sequence-based genetic diversity of this aromatic herb is not yet known. In this report, we present our studies on the phylogeography of this species using trnL-trnF intergenic spacer of plastid genome as the DNA barcode for isolates from Indian subcontinent. Our pairwise distance analyses indicated that genetic heterogeneity of isolates remained quite low, with overall mean nucleotide p-distance of 5 × 10(-4). However, our sensitive phylogenetic analysis using maximum likelihood framework was able to reveal subtle intraspecific molecular evolution of this species within the subcontinent. All isolates except that from North-Central India formed a distinct phylogenetic clade, notwithstanding low bootstrap support and collapse of the clade in Bayesian Inference. North-Central isolates occupied more basal position compared to other isolates, which is suggestive of its evolutionarily primitive status. Indian isolates formed a monophyletic and well-supported clade within O. tenuiflorum clade, which indicates a distinct haplotype. Given the vast geographical area of more than 3 million km(2) encompassing many exclusive biogeographical and ecological zones, relatively low rate of evolution of this herb at this locus in India is particularly interesting.

    The use of compounds which can selectively protect normal tissues against radiation injury is of immense use because in addition to it protecting the normal tissue, will also permits use of higher doses of radiation to obtain better cancer control and possible cure. However, most of the radio protective compounds investigated possess inadequate clinical application principally due to their inherent systemic toxicity at their optimal protective concentrations. Plants commonly used as medicinal and dietary agents have recently been the focus of attention and studies have shown that Ocimum sanctum Linn. commonly known as the Holy Basil and its water soluble flavonoids, orientin and vicenin protects experimental animals against the radiation-induced sickness and mortality at nontoxic concentrations. Studies with tumor bearing mice have also shown that both Tulsi extract and its flavonoids selectively protect the normal tissues against the tumoricidal effects of radiation. Preclinical studies have also shown that the aqueous extract of the Tulsi leaves; its flavanoids orientin and vicenin, and eugenol, the principal nonpolar constituent present in Tulsi prevent radiation-induced clastogenesis. Mechanistic studies have indicated that free radical scavenging, antioxidant, metal chelating and anti-inflammatory effects may contribute toward the observed protection. In addition, clinical studies with a small number of patients have shown that Tulsi was effective as a radio protective agent. This review summarizes the results related to the radio protective properties of Tulsi and its phytochemicals and also emphasizes the aspects that warrant future research to establish its use as a radio protective agent.

    Poststernotomy mediastinitis continues to be an infrequent but serious complication after cardiac surgery. We present a case of a 59-year-old man who developed a deep sternal wound infection after an emergency cardiac surgery. Omental transposition flap was used to cover the sternal defect. Several days later, the patient developed a transverse colon herniation into the anterior mediastinum that required emergency exploration and colon resection. The patient survived after a difficult hospital course. Indications, technical points, and possible complications of using omental flap transposition are discussed. PMID:17439030

    Full Text Available Leiomyosarcoma of the adrenal gland is extremely rare in the literature. We present a patient with an adrenal leiomyosarcoma originating from the adrenal vein, the pathologic findings and management. A 66-year-old man who was a hepatitis B virus carrier was found to have a huge left suprarenal mass on sonography and computed axial tomography. A huge tumor in the left suprarenal area with a markedly engorged adrenal vein was found during an adrenalectomy. The tumor thrombus extended into the renal vein, close to the inferior vena cava. The left adrenal gland with the whole tumor thrombus was removed completely. Microscopically, the adrenal gland was compressed but not invaded by the spindle cell tumor, which was composed of interlacing fascicles of neoplastic smooth muscle cells. The tumor was localized within the adrenal vein and arose from the venous wall. The patient had no local recurrence for 18 months after en bloc excision of the tumor. We suggest that en bloc excision with a clear and adequate surgical margin is the most important cure procedure for adrenal leiomyosarcoma.

  2. Transposition of the acetabulum after iliac ischial osteotomy in the treatment of hip dysplasia in infants

    Владимир Евгеньевич Басков

    2016-06-01

    Full Text Available Background. Transposition of the acetabulum after pelvic osteotomy is the most effective surgical method to treat dysplastic hip joint disorders in patients of different ages. According to Salter, iliac osteotomy of the pelvis is the main surgical method used to correct dysplastic acetabulum in 7- and 8-year-old children. In older patients, the pubic symphysis and pelvic ligaments become more rigid, which significantly limits the degree of rotation of the acetabulum. In these cases, a triple pelvic osteotomy is performed to enhance the mobility of the acetabular fragment. This pubic bone osteotomy is performed near the femoral neurovascular bundle, which may be damaged during the procedure.Aim. To describe a technique for transposition of the acetabulum after iliac and ischial osteotomy of the pelvis, which was developed to reduce trauma, prevent vascular complications, and increase postoperative stability of the pelvic ring.Materials and methods. A method developed by the authors for transposition of the acetabulum after iliac and sciatic pelvic osteotomy is described in detail. The surgical method was performed 99 times on 89 children with dysplastic hip joint disorders, and the results are presented.Conclusion. Transposition of the acetabulum after iliac and ischial pelvic osteotomy is an effective treatment for dysplastic instability of the acetabulum in children aged 9–16 years. The procedure is indicated when it is necessary to rotate the acetabular fragment by more than 25°, and there is no need for hip medialization.

    2015-04-01

    Full Text Available Em seu prefácio à coletânea Fábulas italianas, Calvino toma os contos dos irmãos Grimm (1812 como modelo, mas critica seu caráter violento e “sanguinário”. Ele imita rigorosamente a coletânea dos autores alemães, selecionando o mesmo número de fábulas (200 e também decide traduzir todos os textos, escritos originalmente em dialeto, para a língua italiana, adaptando arbitrariamente enredos e nomes. Em relação a Giambattista Basile [BASILE: 1999 e 2000], autor de Lu cunto de li cunti (ou Pentamerone, uma coletânea de 50 contos, redigidos em napolitano em 1646, um autor celebrado, imitado e traduzido pelos irmãos Grimm, Calvino foi francamente omisso. Trata-se de um autor proto-expressionista, que apresenta em sua obra as versões mais antigas de muitos contos conhecidos (Cinderela, Branca de Neve, O Gato de botas, A bela adormecida entre outros foi traduzido para o italiano pelo filósofo Benedetto Croce somente em 1925. O assim-chamado Pentamerone (por associação ao Decameron de Boccaccio, teve uma surpreendente tradução para o alemão, publicada em 1846, graças ao estímulo dos irmãos Grimm, que veneravam o autor italiano como grande mestre do conto maravilhoso. O triângulo virtual que se forma entre Calvino, os irmãos Grimm e Basile, tem num de seus ângulos a denegação calviniana do autor napolitano e no outro, a obra maior deste autor, a qual reforça a importância, vivacidade e consistência dos dialetos na tradição literária italiana. Entre Calvino e Basile, os irmãos Grimm parecem representar uma mediação singular e típica entre a cultura alemã e a italiana.

  12. Mechanical buckling of veins under internal pressure.

    Martinez, Ricky; Fierro, Cesar A; Shireman, Paula K; Han, Hai-Chao

    2010-04-01

    Venous tortuosity is associated with multiple disease states and is often thought to be a consequence of venous hypertension and chronic venous disease. However, the underlying mechanisms of vein tortuosity are unclear. We hypothesized that increased pressure causes vein buckling that leads to a tortuous appearance. The specific aim of this study was to determine the critical buckling pressure of veins. We determined the buckling pressure of porcine jugular veins and measured the mechanical properties of these veins. Our results showed that the veins buckle when the transmural pressure exceeds a critical pressure that is strongly related to the axial stretch ratio in the veins. The critical pressures of the eight veins tested were 14.2 +/- 5.4 and 26.4 +/- 9.0 mmHg at axial stretch ratio 1.5 and 1.7, respectively. In conclusion, veins buckle into a tortuous shape at high lumen pressures or reduced axial stretch ratios. Our results are useful in understanding the development of venous tortuosity associated with varicose veins, venous valvular insufficiency, diabetic retinopathy, and vein grafts. PMID:20094913

    Imao, Tetsuya; Amano, Toshiyasu; Takemae, Katsurou

    2011-02-01

    A 43-year-old woman was referred to our clinic for evaluation of a left retroperitoneal mass. She presented to our internal medicine department complaining of back pain. Computed tomography (CT) scan revealed a left retroperitoneal mass 55 mm in size in the hilum of the left kidney. Enhanced CT scan and magnetic resonance imaging (MRI) disclosed a poorly staining mass. Metaiodobenzylguanidine scintigraphy demonstrated no accumulation in the mass; moreover, endocrinologic examination was normal. Laparoscopic resection of the left retroperitoneal tumor was attempted; however, strong adhesion between the tumor and the left renal vein was encountered. Thus, left nephrectomy after open conversion was performed. Histological findings indicated leiomyosarcoma originating from the left renal vein. The postoperative course has been uneventful; neither recurrence nor metastasis is evident 2 years postsurgery. PMID:20694494

    2015-10-01

    Full Text Available As the Person‟s/Organization‟s Private information‟s are becoming very easy to access, the demand for a Simple, Convenient, Efficient, and a highly Securable Authentication System has been increased. In considering these requirements for data Protection, Biometrics, which uses human physiological or behavioral system for personal Identification has been found as a solution for these difficulties. However most of the biometric systems have high complexity in both time and space. So we are going to use a Real time Finger-Vein recognition System for authentication purposes. In this paper we had implemented the Finger Vein Recognition concept using MATLAB R2013a. The features used are Lacunarity Distance, Blanket Dimension distance. This has more accuracy when compared to conventional methods.

    Toxoplasma gondii, Cryptosporidium spp. and Giardia intestinalis are emerging pathogen parasites in the food domain. However, without standardized methods for their detection in food matrices, parasitic foodborne outbreaks remain neglected. In this study, a new immunomagnetic separation assay (IMS Toxo) targeting the oocyst's wall of T. gondii was developed using a specific purified monoclonal antibody. Performance of this IMS Toxo coupled to microscopic and qPCR analyses was evaluated in terms of limit of detection (LOD) and recovery rate (RR) on: i) simple matrix (LOD = 5 oocysts; RR between 5 and 56%); ii) raspberries and basil (LOD = 33 oocysts/g; RR between 0.2 and 35%). Finally, to simultaneously extract the three protozoa from these food matrices, T. gondii oocysts were directly concentrated (without IMS Toxo) from the supernatant of the IMS of Cryptosporidium and Giardia (oo)cysts. This strategy associated to qPCR detection led to LOD <1 to 3 (oo)cysts/g and RR between 2 and 35%. This procedure was coupled to RT-qPCR analyses and showed that the three protozoa persisted on the leaves of basil and remained viable following storage at 4 °C for 8 days. These data strengthen the need to consider these protozoa in food safety. PMID:27052700

  16. Vein harvesting and techniques for infrainguinal bypass.

    Albäck, Anders; Saarinen, Eva; Venermo, Maarit

    2016-04-01

    In order to achieve good long term results after bypass surgery, alongside with good inflow and outflow arteries, the bypass graft material also has an important role. The best patency and limb salvage rates are achieved with autologous vein. If great saphenous vein is not available, acceptable long-term results can be achieved with arm veins and lesser saphenous vein. The quality and size of the vein are important. A small-caliber vein, increased wall thickness, postphlebitic changes and varicosities are associated with a risk of early failure. Preoperative vein mapping with ultrasound reduces readmissions and postoperative surgical site infections. During the mapping, the vein to be used and its main tributaries are marked with a permanent marker pen. To reduce wound complication rates we recommend bridged incisions in vein harvesting. Endoscopic vein harvesting seems to have no benefit compared to open techniques in lower limb bypasses, and has been associated with higher risk of primary patency loss at one year. With deep tunneling of the graft the problems caused by wound infection can be avoided. PMID:26837257

    2012-11-01

    Transpositions of the gypsy retrotransposon in the Drosophila melanogaster genome are controlled by the flamenco locus, which is represented as an accumulation of defective copies of transposable elements. In the present work, genetic control by the flamenco locus of the transcriptional and transpositional activities of the Tirant retrotransposon from the gypsy group was studied. Tissue-specific expression of Tirant was detected in the tissues of ovaries in a strain mutant for the flamenco locus. Tirant was found to be transpositionally active in isogenic D. melanogaster strains mutant for the flamenco locus. The sites of two new insertions have been localized by the method of subtractive hybridization. It has been concluded from the results obtained that the flamenco locus is involved in the genetic control of Tirant transpositions. PMID:23297482

    2008-01-01

    Knowledge of variations in the origin, course and termination of external jugular vein may be important for surgeons, radiologists, and plastic surgeons. In this report, we present a variation in the origin of the external jugular vein and its abnormal communication with the cephalic vein. The external jugular vein was formed by the union of facial and retromandibular veins. Its course and termination were normal but it communicated with the cephalic vein through a large communicating vein, w...

  19. Preduodenal portal vein: its surgical significance.

    Makey, D A; Bowen, J C

    1978-11-01

    Preduodenal portal vein is a rare anatomical variant which may be one of many anomalies in the neonate with duodenal "atresia." Preduodenal portal vein also may be an occasional finding in an adult undergoing biliary, gastric, or pancreatic surgery. Awareness and recognition of the anomaly are essential for the avoidance of injury during such operations. We report here a symptomless patient whose preduodenal portal vein was discovered at cholecystectomy. PMID:715684

  20. Percutaneous embolization of a giant collateral vessel originating from the azygos vein via the inferior vena cava.

    Witzke, Christian; Bhatt, Ami; Inglessis, Ignacio

    2013-11-15

    We present the case of a 45-year-old man with univentricular heart, small outlet chamber, and L-transposition of the great vessels. As an infant, the patient underwent multiple palliative surgical interventions. He presented with worsening dyspnea and fatigue and was found to have systemic oxygen saturation of 85% on 2 L of oxygen by nasal cannula, whereas he had chronically remained between 90 and 95% throughout most of adulthood. There was no evidence of significant valvular regurgitation or stenosis, nor was there an overt intracardiac shunt by echocardiography. Cardiac CT and cardiac MRI revealed a large serpiginous systemic to pulmonary venovenous collateral located behind the left atrium. The collateral drained into the lower right pulmonary vein as it entered the left atrium. The tributary veins to the "giant" collateral were determined by these images modalities. The patient underwent a percutaneous embolization of this giant venovenous collateral via a remnant supracardinal vein originating from the infrarenal inferior vena cava using two Amplatzer Vascular Plug II. Immediately after the procedure the patient's oxygen saturation increased to 90% on room air at rest. At 2 months follow-up the patient had a marked clinical improvement with oxygen saturation as high as 95% on room air while walking. Our case illustrates a successful embolization of a giant collateral via an embryological venous remnant connecting the IVC to the azygos system. PMID:22936600

  1. Analysis of the Superconducting Cable Transposition in Low Resistance CICC Joint

    Zhu, You-hua

    2000-08-01

    In an integrated structure low resistance CICC joint, current is conducted by outer cable strands coming into touch with the conductive Cu sole. So it is an important condition for satisfying joint performance that each strand of the cable inside the joint is able to come to the outermost by transposition. This paper presents analysis, calculation and figures for the strand transposition. According to the twist procedures of the superconducting cable, the author computed the actual pitch of each stage cable, consecutively computed the projection of each stage cable on the axis of the cable (z axis) and the corresponding twist angle as the z coordinate changes, which is then drawn by AutoCAD. From the results shown in the figures, the minimal cable length, which enables each strand to transpose almost equally to the outermost of the cable in such a length, can be determined as the optimal joint length.

  2. RAG1 and RAG2 in V(D)J recombination and transposition.

    Fugmann, S D

    2001-01-01

    RAG1 and RAG2 are the key components of the V(D)J recombinase machinery that catalyses the somatic gene rearrangements of antigen receptor genes during lymphocyte development. In the first step of V(D)J recombination--DNA cleavage--the RAG proteins act together as an endonuclease to excise the DNA between two individual gene segments. They are also thought to be involved in the subsequent DNA joining step. In vitro, the RAG proteins catalyze the integration of the excised DNA element into target DNA completing a process similar to bacterial transposition. In vivo, this reaction is suppressed by an unknown mechanism. The individual roles of RAG1 and RAG2 in V(D)J recombination and transposition reactions are discussed based on mutation analyses and structure predictions. PMID:11417858

  3. The IS200/IS605 Family and "Peel and Paste" Single-strand Transposition Mechanism.

    He, S; Corneloup, A; Guynet, C; Lavatine, L; Caumont-Sarcos, A; Siguier, P; Marty, B; Dyda, F; Chandler, M; Ton Hoang, B

    2015-08-01

    This chapter presents an analysis of the organization and distribution of the IS200/IS605 family of insertion sequences (IS). Members of this family are widespread in both bacteria and archaea. They are unusual because they use obligatory single-strand DNA intermediates, which distinguishes them from classical IS. We summarize studies of the experimental model systems IS608 (from Helicobacter pylori) and ISDra2 (from Deinococcus radiodurans) and present biochemical, genetic, and structural data that describe their transposition pathway and the way in which their transposase (an HuH rather than a DDE enzyme) catalyzes this process. The transposition of IS200/IS605 family members can be described as a "Peel-and-Paste" mechanism. We also address the probable domestication of IS200/IS605 family transposases as enzymes involved in multiplication of repeated extragenic palindromes and as potential homing endonucleases in intron-IS chimeras.

  4. Endovenous laser therapy for varicose vein

    Erwin Mulia

    2013-05-01

    Full Text Available Laser has become a useful technology in treating venous incompetence especially superficial venous disease. Introduction of endovenous thermal ablation through endovenous laser therapy helped by duplex ultrasound guidance has provided an alternative for traditional saphenous vein stripping. High success rate, minor complications, and minimally invasive technique provide the advantages over traditional treatment. In this case illustrated, the endovenous laser therapy used for great saphenous varicose vein. Yet, future development in endovenous laser therapy is still needed and only long term follow-up and uniform reporting standards will provide the answers.

  6. Tn5-mediated transposition of plasmid DNA after transduction to Myxococcus xanthus.

    Downard, J S

    1988-01-01

    After coliphage P1-mediated transfer of Tn5-containing plasmid DNA from Escherichia coli to Myxococcus xanthus, transductants were identified which contained plasmid sequences integrated at many sites on the bacterial chromosome. The unaltered plasmid DNA sequences in these transductants were apparently flanked by intact Tn5 or IS50 sequences. These results suggest that Tn5-mediated transposition has occurred and provide a method for integrating plasmid DNA into the M. xanthus chromosome with...

  7. Controlling DNA degradation from a distance: a new role for the Mu transposition enhancer

    Choi, Wonyoung; Saha, Rudra P; Jang, Sooin; Harshey, Rasika M.

    2014-01-01

    Phage Mu is unique among transposable elements in employing a transposition enhancer. The enhancer DNA segment is the site where the transposase MuA binds and makes bridging interactions with the two Mu ends, interwrapping the ends with the enhancer in a complex topology essential for assembling a catalytically active transpososome. The enhancer is also the site at which regulatory proteins control divergent transcription of genes that determine the phage lysis-lysogeny decision. Here we repo...

  8. Improving the accuracy of flood forecasting with transpositions of ensemble NWP rainfall fields considering orographic effects

    Yu, Wansik; Nakakita, Eiichi; Kim, Sunmin; Yamaguchi, Kosei

    2016-08-01

    The use of meteorological ensembles to produce sets of hydrological predictions increased the capability to issue flood warnings. However, space scale of the hydrological domain is still much finer than meteorological model, and NWP models have challenges with displacement. The main objective of this study to enhance the transposition method proposed in Yu et al. (2014) and to suggest the post-processing ensemble flood forecasting method for the real-time updating and the accuracy improvement of flood forecasts that considers the separation of the orographic rainfall and the correction of misplaced rain distributions using additional ensemble information through the transposition of rain distributions. In the first step of the proposed method, ensemble forecast rainfalls from a numerical weather prediction (NWP) model are separated into orographic and non-orographic rainfall fields using atmospheric variables and the extraction of topographic effect. Then the non-orographic rainfall fields are examined by the transposition scheme to produce additional ensemble information and new ensemble NWP rainfall fields are calculated by recombining the transposition results of non-orographic rain fields with separated orographic rainfall fields for a generation of place-corrected ensemble information. Then, the additional ensemble information is applied into a hydrologic model for post-flood forecasting with a 6-h interval. The newly proposed method has a clear advantage to improve the accuracy of mean value of ensemble flood forecasting. Our study is carried out and verified using the largest flood event by typhoon 'Talas' of 2011 over the two catchments, which are Futatsuno (356.1 km2) and Nanairo (182.1 km2) dam catchments of Shingu river basin (2360 km2), which is located in the Kii peninsula, Japan.

    Over the last three years of hearing aid dispensing, it was observed that among 74 subjects fitted with a linear octave frequency transposition (LOFT) hearing aid, 60 reported partial or complete tinnitus suppression during day and night, an effect still lasting after several months or years of daily use. We report in more details on 38 subjects from whom we obtained quantified measures of tinnitus suppression through visual analog scaling and several additional psychoacoustic and audiometric...

  10. Regiochemical Control in the Metal-Catalyzed Transposition of Allylic Silyl Ethers

    Hansen, Eric C.; Lee, Daesung

    2006-01-01

    A novel mode of regiochemical control over the allylic [1,3]-transposition of silyloxy groups catalyzed by Re2O7 has been developed. This strategy relies on a cis-oriented vinyl boronate, generated from the Alder ene reaction of homoallylic silyl ethers and alkynyl boronates, to trap out the allylic hydroxyl group. The resulting cyclic boronic acids are excellent partners for cross coupling reactions. High chirality transfer is observed for the rearrangement of enantioenriched allylic silyl e...

  12. Optical transposition transform interconnects using a free-space and fiber hybrid module

    Popelek, Jan; Li, Yao

    1999-04-01

    Cross-connect switch is a popular switching architecture for telecom and datacom applications. Using various switching components and a k-shuffle interconnect, a cross-connect switch can be configured for general-purpose, blocking as well as non-blocking networking applications. We show that a 1D k-shuffle interconnect pattern is topologically equivalent to a 2D transposition transform pattern. Based on this observation and using space-invariant optical components, the transposition transform interconnect is experimentally implemented. To achieve a sensible packing, we propose to incorporate fiber arrays into the implementation so that the interconnect offers connectorized plug-and-play capability with its switching arrays. Experimental results of implementing a 256 X 256 connectorized free-space and fiber hybrid transposition transform interconnect for cross-connect switching are presented. Key parameters, such as insertion loss, cross- talk, and bit-error-rate of the hybrid interconnect module are measured. Video data are used to demonstrate interconnect quality of various link channels. Scalability to larger interconnects are speculated.

  13. Effect of brushwood transposition on the leaf litter arthropod fauna in a cerrado area

    Paula Cristina Benetton Vergílio

    2013-10-01

    Full Text Available The results of ecological restoration techniques can be monitored through biological indicators of soil quality such as the leaf litter arthropod fauna. This study aimed to determine the immediate effect of brushwood transposition transferred from an area of native vegetation to a disturbed area, on the leaf litter arthropod fauna in a degraded cerrado area. The arthropod fauna of four areas was compared: a degraded area with signal grass, two experimental brushwood transposition areas, with and without castor oil plants, and an area of native cerrado. In total, 7,660 individuals belonging to 23 taxa were sampled. Acari and Collembola were the most abundant taxa in all studied areas, followed by Coleoptera, Diptera, Hemiptera, Hymenoptera, and Symphyla. The brushwood transposition area without castor oil plants had the lowest abundance and dominance and the highest diversity of all areas, providing evidence of changes in the soil community. Conversely, the results showed that the presence of castor oil plants hampered early succession, negatively affecting ecological restoration in this area.

  14. Transposon display supports transpositional activity of elements in species of the saltans group of Drosophila

    Nathalia De Setta; Ana Paula Pimentel Costa; Fabrício Ramon Lopes; Marie-Anne Van Sluys; Cláudia Márcia Aparecida Carareto

    2007-01-01

    Mobilization of two element subfamilies (canonical and O-type) from Drosophila sturtevanti and D. saltans was evaluated for copy number and transposition activity using the transposon display (TD) technique. Pairwise distances between strains regarding the insertion polymorphism profile were estimated. Amplification of the element based on copy number estimates was highly variable among the strains (D. sturtevanti, canonical 20.11, O-type 9.00; D. saltans, canonical 16.4, O-type 12.60 insertions, on average). The larger values obtained by TD compared to our previous data by Southern blotting support the higher sensitivity of TD over Southern analysis for estimating transposable element copy numbers. The higher numbers of the canonical element and the greater divergence in its distribution within the genome of D. sturtevanti (24.8%) compared to the O-type (16.7%), as well as the greater divergence in the distribution of the canonical P element, between the D. sturtevanti (24.8%) and the D. saltans (18.3%) strains, suggest that the canonical element occupies more sites within the D. sturtevanti genome, most probably due to recent transposition activity. These data corroborate the hypothesis that the O-type is the oldest subfamily of elements in the saltans group and suggest that the canonical element is or has been transpositionally active until more recently in D. sturtevanti.

  15. Anterior subcutaneous transposition of the ulnar nerve improves neurological function in patients with cubital tunnel syndrome

    Wei Huang

    2015-01-01

    Full Text Available Although several surgical procedures exist for treating cubital tunnel syndrome, the best surgical option remains controversial. To evaluate the efficacy of anterior subcutaneous transposition of the ulnar nerve in patients with moderate to severe cubital tunnel syndrome and to analyze prognostic factors, we retrospectively reviewed 62 patients (65 elbows diagnosed with cubital tunnel syndrome who underwent anterior subcutaneous transposition. Preoperatively, the initial severity of the disease was evaluated using the McGowan scale as modified by Goldberg: 18 patients (28% had grade IIA neuropathy, 20 (31% had grade IIB, and 27 (42% had grade III. Postoperatively, according to the Wilson & Krout criteria, treatment outcomes were excellent in 38 patients (58%, good in 16 (25%, fair in 7 (11%, and poor in 4 (6%, with an excellent and good rate of 83%. A negative correlation was found between the preoperative McGowan grade and the postoperative Wilson & Krout score. The patients having fair and poor treatment outcomes had more advanced age, lower nerve conduction velocity, and lower action potential amplitude compared with those having excellent and good treatment outcomes. These results suggest that anterior subcutaneous transposition of the ulnar nerve is effective and safe for the treatment of moderate to severe cubital tunnel syndrome, and initial severity, advancing age, and electrophysiological parameters can affect treatment outcome.

    Full Text Available Aims. To report the results of lateral rectus muscle recession, medial rectus muscle resection, and superior oblique muscle transposition in the restoration and maintenance of ocular alignment in primary position for patients with total third-nerve palsy. Methods. The medical records of patients who underwent surgery between March 2007 and September 2011 for total third-nerve palsy were reviewed. All patients underwent a preoperative assessment, including a detailed ophthalmologic examination. Results. A total of 6 patients (age range, 14–45 years were included. The median preoperative horizontal deviation was 67.5 Prism Diopter (PD (interquartile range [IQR] 57.5–70 and vertical deviation was 13.5 PD (IQR 10–20. The median postoperative horizontal residual exodeviation was 8.0 PD (IQR 1–16, and the vertical deviation was 0 PD (IQR 0–4. The median correction of hypotropia following superior oblique transposition was 13.5 ± 2.9 PD (range, 10–16. All cases were vertically aligned within 5 PD. Four of the six cases were aligned within 10 PD of the horizontal deviation. Adduction and head posture were improved in all patients. All patients gained new area of binocular single vision in the primary position after the operation. Conclusion. Lateral rectus recession, medial rectus resection, and superior oblique transposition may be used to achieve satisfactory cosmetic and functional results in total third-nerve palsy.

  17. Reactions of carbon radicals generated by 1,5-transposition of reactive centers

    ZIVORAD CEKOVIC

    2005-03-01

    Full Text Available Radical intermediates can undergo specific reactions, such as intramolecular rearrangements, i.e., the transpositions of radical centers, which are not known in classical ionic organic reactions. 1,5-Transposition of a radical center to a non-activated carbon atom are of great synthetic importance. It can be successfully applied for the introduction of different functional groups (oxygen, nitrogen, sulfur, halogens onto a carbon atom remote from the present functional group. In addition to functionalization of a remote non-activated carbon atom, the formation of new C-C bonds on the d-carbon atom have also been achieved. 1,5-Transposition of the radical centers takes place from alkoxyl, aminyl and carbon radicals to a remote carbon atom. Relocation of the radical centers preferentially involves 1,5-transfer of a hydrogen atom, although migrations of some other groups are known. The reactions of the carbon radical generated by 1,5-relocation of the radical center are presented and their synthetic applications are reviewed.

    This study describes the effect of water stress and storage time on the content of anthocyanins and other phenolics in different genotypes of fresh sweet basil (Ocimum basilicum L.). Purple and green Iranian cultivars and a Genovese variety were exposed to a control (100% of the field capacity, FC) and to water stress of mild and severe deficit irrigation treatments (25 and 50 DI corresponding to 75 and 50% FC, respectively). The individual characterization by HPLC-DAD-ESI/MS(n) and the MS fragmentation pathway of anthocyanins are described. A 50% increase in the anthocyanin content was observed in 50 DI after storage. Water stress markedly enhanced the content of phenolic acids after storage in the three genotypes. Water stress can be an efficient way to help the sustainability of water resources, enriching the content of phenolic compounds that may be beneficial to human health. PMID:26473474

  1. Antimicrobial activity of sweet basil and thyme against salmonella enterica serotype Enteritidis in egg-based pasta

    2015-01-01

    Full Text Available Salmonella enterica serotype Enteritidis is known as one of the most common pathogenic bacteria causing salmonellosis in humans. Raw materials of animal origin (eggs, chicken meat are frequent vectors that transmit this bacterium. Since eggs are used for the production of pasta, due to insufficient thermal treatment during pasta drying, they can be a potential risk to consumer health. Different essential oils of herbs can be used to reduce present pathogenic microorganisms. This paper compares a decrease in the number of Salmonella enterica serotype Enteritidis (D ATCC 13076 and Salmonella enterica serotype Enteritidis isolated from outbreaks of salmonellosis in egg-based pasta under the influence of thyme and sweet basil essential oils. The results indicate that the utilized oils were more effective against the epidemic strain than the ATCC strain. In addition, thyme oil caused a more significant inhibition of Salmonella enterica serotype Enteritidis during the production process.

  4. Ultrasound-guided subclavian vein catheterization

    To assess the usefulness of the ultrasound-guided subclavian vein catheterization in difficult patients. We tried subclavian vein catheterization in 18 patients in which conventional blind technique failed(N=9): or was complicated by hemothorax or pneumothorax(N=3): or was prohibited by respirator care(N=4) and severe thoracic deformity(N=2). Initially, the patency of subclavian vein was evaluated with ultrasonography, and then, the puncture of the subclavian vein was performed under the guidance of ultrasonography. Under the fluoroscopy, the patency of the proximal subclavian vein and the superior vena cava was evaluated after contrast-media injection and a catheter was inserted into the subclavian vein and accurately positioned at the superior vena cava. Successful catheterization was performed in 17 patients. In the remaining one patient, we did not perform catheterization because of bilateral subclavian vein thrombosis detected during the procedure. There were no procedure-related complications. Ultrasound-guided subclavian vein catheterization is an easy and safe method even in difficult cases

  7. The Effect of Static Magnetic Forces on Water Contents and Photosynthetic Pigments in Sweet Basil Ocimum basilicum L. (Lamiaceae)

    Three different magnetic regimes; aerial, surface and buried; each with three different forces, have been used to investigate their effects on the water contents and photosynthetic pigments of sweet basil plants (Ocimum basilicum L.). Two groups of sweet basil seeds, Ocimum basilicum L. have been cultivated, one under normal conditions and the second has been subdivided into three portion (aerial, surface and buried) to examine the effect of different magnetic forces coming from the three directions on the resulted plants. At all directions of magnets, water contents have been significantly affected by the magnetic forces. Chlorophyll A and carotene contents have been affected, as well, according to the three magnetic forces coming from soil surface regime only. Chlorophyll B did not significantly affected by differences magnetic forces in the three regimes, but it is affected by magnetism wherever its direction or force. But all the photosynthetic pigments contents (Chlorophyll A, B and Carotenes) decreased significantly than the control in the three magnetic regimes., but without any effect according to differences in the magnetic force in the aerial and burried regimes of magnetism. It was concluded that magnetism affects both water absorption and retention , the most influenced regime was the aerial magnets followed by the surface and buried ones. This result can be interpreted by the ionization of water which makes water ions respond to magnetic forces. Photosynthetic pigments have been decreased significantly by the exposure to magnetic fields, irrespective to its direction or force and this may be due to the effect of magnetic fields on the reduction in plastids inside the cells.

    2013-10-01

    Full Text Available Mass production of medicinal and aromatic plants under hydroponic systems and especially in areas with saline soils is very important. An experiment was conducted to evaluate the interaction of salinity stress and foliar application of zinc (Zn on hydroponically-grown basil (Ocimum basilicum L.. The factorial experiment was arranged as randomized complete blocks design, with two salinity levels (0 and 50 mM NaCl and three Zn levels (0, 100 and 200 mg/L as ZnSO4,7H2O and three replications. Some growth characteristics such as height, leaf surface area, fresh and dry weight of leaves, stem and whole plant, chlorophyll index, harvest index and yield of dry leaves per m2 were measured. After extraction of essential oil, the oil yield was calculated based on oil content in the plant. The results showed that salinity stress adversely affected all growth characteristics as well as essential oil content and yield. Despite the generally accepted hypothesis, Zn application not only had no impact on reducing the negative effects of salinity, but also showed no significant difference between the control plants (no salinity. The highest essential oil content and yield were recorded for control plants. Therefore, it is concluded that under the hydroponics system, basil is sensitive to 50 mM salinity, and Zn foliar application up to 200 mg/L had no positive impact on the reduction of negative effects of salinity. Thus, control nutrient solution has appropriate amount of Zn for salinity stress conditions.

    2013-12-01

    Serpentinization of ultramafic rocks has wide ranging implications for the petrology, rheology, and petrophysical properties of the oceanic lithosphere. During hydration of the peridotite, fluid-rock ratios and temperature control mineral formation in the veins. We studied a partly serpentinized peridotite from the Santa Elena ophiolite complex in Costa Rica and tracked element mobility during water-rock interaction. Serpentinization of the studied harzburgite is around 30 to 40%, with serpentinization of olivine being more advanced than serpentinization of orthopyroxene. Element mapping and point analyses show that the veins preserve characteristic element distributions within orthopyroxene and olivine, and with distance to orthopyroxene-hosted serpentine veins. With increasing distance from the orthopyroxene the following vein assemblages were observed in olivine: pure serpentine veins, serpentine + brucite veins, serpentine + brucite + magnetite veins. Veins are enriched in SiO2 in the proximity of orthopyroxene suggesting that a net transfer of SiO2 takes place from serpentinizing orthopyroxene to olivine. The magnetite-bearing serpentine veins mostly consist of Mg-rich serpentine (Mg# = 90 - 95) and Fe-rich brucite (Mg# = 70 - 75) finely intergrown. In contrast, the center of these veins contains a thin zone of high-Mg serpentine (Mg# 97), and high-Mg brucite (Mg# 92 - 94) next to magnetite. We infer from thermodynamic calculations that these mineral assemblages are controlled by H2O activity and low SiO2 activities. Within orthopyroxene, serpentine (Mg# = 84 - 89) with an elevated Al2O3 content ( 100 μm and > 200 μm, respectively, from the orthopyroxene. We infer that brucite is not stable in close proximity to orthopyroxene due to elevated SiO2 derived from orthopyroxene breakdown. Orthopyroxene serpentinization results in net transfer of Al2O3 into serpentine, but only in the immediate vicinity of the orthopyroxene. Overall, our study indicates that the

    Retinal vein occlusion (RVO) is a pathology noted for more than 150 years. Although a lot has been written on the matter, it is still a frequent condition with multifactorial etiopathogenesis with many unclear aspects. The RVO pathogenesis has varied systemic and local implications that make it difficult to elaborate treatment guidelines. The management of the patient with RVO is very complex and a multidisciplinary approach is required in order to identify and correct the associated risk factors. Laser therapy remains the gold standard in RVO, but only modest functional improvement has been shown in branch retinal occlusion forms. Multicenter studies of intravitreal drugs present them as an option to combine with laser. Anti-vascular endothelial growth factor, corticosteroids and sustained-release implants are the future weapons to stop disease progression and get a better visual outcome. Consequently, it is useful to clarify some aspects of the pathology that allow a better patient management. PMID:20938213

    Full Text Available Rajiv K Chander,1 Thomas S Monahan1,2 1Section of Vascular Surgery, Department of Surgery, University of Maryland School of Medicine, 2Department of Surgery, Baltimore Veterans Affairs Medical Center, Baltimore, MD, USA Abstract: Duplex ultrasonography is the ideal modality to assess great saphenous vein insufficiency. Duplex ultrasonography incorporates both gray scale images to delineate anatomy and color-Doppler imaging that visualizes the flow of blood in a structure. Assessment of great saphenous vein requires definition of the anatomy, augmentation of flow, evaluation for both superficial and deep vein thrombosis, and determining the presence of reflux. Currently, evolution in the treatment of reflux also relies on ultrasound for the treatment of the disease. Understanding the utilization of the ultrasound for the diagnosis and treatment of greater saphenous vein reflux is important for practitioners treating reflux disease.

    Khatami, Mohammad Reza; Abbasi, Rozita; Sadigh, Gelareh

    2010-10-01

    Central vein catheterization is a routine and relatively safe procedure in critically ill patients. Complications with this procedure depend to the site of catheterization and the skill of the operator. In addition to the common complications with femoral vein catheterization there are some rare usually preventable side effects related to guide wire and catheter. In our patient who underwent femoral catheterization for acute hemodialysis, we report migration of guide wire through the systemic circulation from the femoral vein to the jugular vein. This is a very rare complication that is a human error and is totally preventable by doing the procedure by a skilled doctor and considering the standards described for central vein catheter insertion.

  13. Hand vein recognition based on orientation of LBP

    Bu, Wei; Wu, Xiangqian; Gao, Enying

    2012-06-01

    Vein recognition is becoming an effective method for personal recognition. Vein patterns lie under the skin surface of human body, and hence provide higher reliability than other biometric traits and hard to be damaged or faked. This paper proposes a novel vein feature representation method call orientation of local binary pattern (OLBP) which is an extension of local binary pattern (LBP). OLBP can represent the orientation information of the vein pixel which is an important characteristic of vein patterns. Moreover, the OLBP can also indicate on which side of the vein centerline the pixel locates. The OLBP feature maps are encoded by 4-bit binary values and an orientation distance is developed for efficient feature matching. Based on OLBP feature representation, we construct a hand vein recognition system employing multiple hand vein patterns include palm vein, dorsal vein, and three finger veins (index, middle, and ring finger). The experimental results on a large database demonstrate the effectiveness of the proposed approach.

  15. The effect of essential oil of basil (Ocimum basilicum L.) on UV-induced mutagenesis in Escherichia coli and Saccharomyces cerevisiae

    The antimutagenic potential of essential oil (EO) of basil (Ocimum basilicum L.) and its major constituent linalool were studied with the E. coli K12 and S. cerevisiae D7 assays. In the E. coli assay, EO and linalool inhibited UV-induced mutagenesis in a repair-proficient strain, but had no effect on spontaneous mutagenesis in repair-proficient, nucleotide excision repair-deficient, and mismatch-deficient strains. By testing participation of different mechanisms involved in antimutagenesis, it was concluded that the antimutagenic effect against UV-induced mutagenesis involved decrease of protein synthesis and cell proliferation which led to increased efficiency of nucleotide excision repair. An antimutagenic effect of basil derivatives in S. cerevisiae was not detected. (author)

  17. Superior rectus transposition combined with medial rectus recession for Duane syndrome and sixth nerve palsy

    Mehendale, Reshma A.; Dagi, Linda R.; Wu, Carolyn; Ledoux, Danielle; Johnston, Suzanne; Hunter, David G.

    2013-01-01

    Objective Vertical rectus transposition (VRT) is used to treat abduction limitation, but new vertical deviations and anterior segment ischemia are concerns. Johnston and Crouch described superior rectus transposition (SRT), a procedure in which only the superior rectus muscle is transposed temporally. We describe our results using augmented temporal SRT with adjustable medial rectus muscle recession (MRc) for treatment of Duane syndrome I (DS) and sixth nerve palsy. Methods Retrospective surgical case review of patients undergoing the SRT procedure. Pre- and post-operative orthoptic measurements were recorded. Minimum follow-up was 6 weeks. Main outcome measures included angle of esotropia in primary position and the angle of head turn. Secondary outcomes included duction limitation, stereopsis, and new vertical deviations. Results The review identified seventeen patients (10 with DS and 7 with sixth nerve palsy). SRT+MRc improved esotropia [from 44 PD to 10.1 PD (p< 0.0001)], reduced abduction limitation [from −4.3 to −2.7 (p<0.0001)] and improved compensatory head posture [from 28°to 4° (p<0.0001)]. Stereopsis was recovered in eight patients (p=0.03). Three patients required a reoperation; one for overcorrection and 2 for undercorrection. A new primary position vertical deviation was observed in 2/7 patients with complex sixth nerve palsy and 0/10 DS patients. No patient described torsional diplopia. Conclusions SRT allows for the option of simultaneous medial rectus recession in patients with severe abduction imitation who require transposition surgery. SRT+MRc improved esotropia, head position, abduction limitation, and stereopsis without inducing torsional diplopia. PMID:22332212

  18. Character Decomposition and Transposition Processes in Chinese Compound Words Modulates Attentional Blink.

    Cao, Hongwen; Gao, Min; Yan, Hongmei

    2016-01-01

    The attentional blink (AB) is the phenomenon in which the identification of the second of two targets (T2) is attenuated if it is presented less than 500 ms after the first target (T1). Although the AB is eliminated in canonical word conditions, it remains unclear whether the character order in compound words affects the magnitude of the AB. Morpheme decomposition and transposition of Chinese two-character compound words can provide an effective means to examine AB priming and to assess combinations of the component representations inherent to visual word identification. In the present study, we examined the processing of consecutive targets in a rapid serial visual presentation (RSVP) paradigm using Chinese two-character compound words in which the two characters were transposed to form meaningful words or meaningless combinations (reversible, transposed, or canonical words). We found that when two Chinese characters that form a compound word, regardless of their order, are presented in an RSVP sequence, the likelihood of an AB for the second character is greatly reduced or eliminated compared to when the two characters constitute separate words rather than a compound word. Moreover, the order of the report for the two characters is more likely to be reversed when the normal order of the two characters in a compound word is reversed, especially when the interval between the presentation of the two characters is extremely short. These findings are more consistent with the cognitive strategy hypothesis than the resource-limited hypothesis during character decomposition and transposition of Chinese two-character compound words. These results suggest that compound characters are perceived as a unit, rather than two separate words. The data further suggest that readers could easily understand the text with character transpositions in compound words during Chinese reading. PMID:27379003

  19. Demonstration of IS711 transposition in Brucella ovis and Brucella pinnipedialis

    García-Lobo Juan M

    2008-01-01

    Full Text Available Abstract Background The Brucella genome contains an insertion sequence (IS element called IS711 or IS6501, which is specific to the genus. The copy number of IS711 varies in the genome of the different Brucella species, ranging from 7 in B. abortus, B. melitensis and B. suis to more than 30 in B. ovis and in Brucella strains isolated from marine mammals. At present, there is no experimental evidence of transposition of IS711, but the occurrence of this element with a high copy number in some species, and the isolation of Brucella strains with "ectopic" copies of IS711 suggested that this IS could still transpose. Results In this study we obtained evidence of transposition of IS711 from the B. ovis and B. pinnipedialis chromosomes by using the "transposon trap" plasmid pGBG1. This plasmid expresses resistance to tetracycline only if the repressor gene that it contains is inactivated. The strains B. melitensis 16 M, B. abortus RB51, B. ovis BOC22 (field strain and B. pinnipedialis B2/94, all containing the plasmid pGBG1, were grown in culture media with tetracycline until the appearance of tetracycline resistant mutants (TcR. TcR mutants due to IS711 transposition were only detected in B. ovis and B. pinnipedialis strains. Conclusion Four different copies of IS711 were found to transpose to the same target sequence in the plasmid pGBG1. This demonstrated that IS711 are active in vivo, specially in Brucella species with a high number of IS711 copies as B. ovis and B. pinnipedialis.

    2011-12-01

    Full Text Available Background and the purpose of study: Skin aging is a complex process induced by constant exposure to ultraviolet (UV irradiation and damages human skin. UV generates reactive oxygen species leading to collagen deficiency and eventually skin wrinkling. Basil contains a number of phenolics and favonoids which possess antioxidant properties. The aim of this study was to formulate and investigate the antiaging potential of a cream containing Basil extract. Methods: A single blinded study was conducted using non-invasive methods. Formulation containing 3% of the concentrated extract of Basil was developed by entrapping in the inner aqueous phase of w/o emulsion and base contained no extract. Both creams were stored at different storage conditions of 8°C, 25°C, 40°C and 40°C+ 75% relative humidity to predict their stabilities. The formulation and base were evaluated for their effects on various skin parameters i.e., moisture and trans epidermal water loss (TEWL, volume, energy and surface evaluation of the living skin (SELS. Results: Significant effects (p≤0.05 were observed for both creams in the case of TEWL. The base showed insignificant (p≤0.05 while formulation showed significant effects on skin moisture. Volume, SELS SEr (skin roughness, SEsc (skin scaliness, SEsm (skin smoothness, SEw (skin wrinkles parameter showed significant decline while texture parameter of ‘Energy' showed significant increase. Conclusion: The results statistically indicated that the active formulation containg extract of Basil exert antiaging effects when applied topically.

  7. An Improved Doppler Rate Estimation Approach for Sliding Spotlight SAR Data Based on the Transposition Domain

    She Xiao-qiang

    2014-08-01

    Full Text Available In image processing of high-resolution sliding spotlight SAR, it is important to know the Doppler rate with accuracy; however, traditional Doppler rate estimation algorithms are not very helpful because of the azimuth spectrum folding phenomenon. In this study, an algorithm that works on the transposition domain is proposed to solve this problem. Furthermore, the algorithm is also helpful in obtaining excellent focused images by embedding it in the two-step technique. Finally, the proposed algorithm is verified using computer simulations.

  8. Complete transposition of the large vessels: study with a dynamic spiral scanner and magnetic resonance

    The case is presented of a 19-year-old woman with complete transposition of the large vessels who was admitted to the hospital with chest pain. As a child, she had undergone palliative heart surgery (Mustard's procedure). A study of the chest performed with a dynamic spiral scanner and magnetic resonance revealed an abnormal relationship between ventricles and large vessels, right ventricular hypertrophy and relative obstruction of the superior vena cava as a results of Mustard's procedure, with dilatation of the azygos-hemiazygos system. Both techniques are very useful for the morphological and functional study of the cardiopathy. (Author)

    twofold in the distally resected group. Tissue GLP-2 levels were unchanged in resected rats. The data indicate that transposition of a distal part of the small intestine, and thereby exposure of L cells to a more nutrient-rich chyme, leads to intestinal growth. The adaptive intestinal growth is associated......Glucagon-like peptide 2 (GLP-2), produced by enteroendocrine L-cells, regulates intestinal growth. This study investigates circulating and intestinal GLP-2 levels in conditions with altered L-cell exposure to nutrients. Rats were allocated to the following experimental groups: ileal......-jejunal transposition, resection of the proximal or distal half of the small intestine, and appropriate sham-operated controls. After two weeks, ileal-jejunal transposition led to pronounced growth of the transposed segment and also of the remaining intestinal segments. Plasma GLP-2 levels increased twofold, whereas...

    Transposition of mitochondrial DNA into the nucleus, which gives rise to nuclear mitochondrial DNAs (NUMTs), has been well documented in eukaryotes. However, very few studies have assessed the frequency of these transpositions during the evolutionary history of a specific taxonomic group. Here we used the horseshoe bats (Rhinolophus) as a case study to determine the frequency and relative timing of nuclear transfers of mitochondrial control region sequences. For this, phylogenetic and coalescent analyzes were performed on NUMTs and authentic mtDNA sequences generated from eight horseshoe bat species. Our results suggest at least three independent transpositions, including two ancient and one more recent, during the evolutionary history of Rhinolophus. The two ancient transpositions are represented by the NUMT-1 and -2 clades, with each clade consisting of NUMTs from almost all studied species but originating from different portions of the mtDNA genome. Furthermore, estimates of the most recent common ancestor for each clade corresponded to the time of the initial diversification of this genus. The recent transposition is represented by NUMT-3, which was discovered only in a specific subgroup of Rhinolophus and exhibited a close relationship to its mitochondrial counterpart. Our similarity searches of mtDNA in the R. ferrumequinum genome confirmed the presence of NUMT-1 and NUMT-2 clade sequences and, for the first time, assessed the extent of NUMTs in a bat genome. To our knowledge, this is the first study to report on the frequency of transpositions of mtDNA occurring before the common ancestry of a genus. PMID:26809101

    2012-01-01

    To the best of our knowledge, a portal vein aneurysm presenting with obstructive jaundice has not been reported in the literature. The preferred treatment for these aneurysms is surgical and a shunting procedure should be considered in cases with portal hypertension to preserve portal vein flow when portal hypertension is present or is secondary to the aneurysm itself. In our case, due to patient′s advanced age and co-morbidities, an endoscopic biliary stent was placed which led to successful...

  16. Branch Retinal Vein Occlusion and Its Management

    Desmond; Archer

    1992-01-01

    The natural course of Branch Retinal Vein Occlusion is determined by the site and completeness of the occlusion, the integrity of arterial perfusion to the affected sector and the efficiency of the developing collateral circulation. Most patients with tributary vein occlusion have some capillary fall out and microvascular incompetence in the distribution of the affected retina and vision is significantly compromised in over 50% of patients who have either chronic macular oedema or ischemia involving the...

    2007-01-01

    Primary venous leiomyosarcoma is rare. We report the case of a primary leiomyosarcoma of the left innominate vein, with neoplastic thrombus extending into the left jugular and subclavian veins. The tumor was curatively resected en bloc with anterior mediastinal and laterocervical lymphatics, through a median sternotomy prolonged into left cervicotomy. Primary venous sarcomas may be associated with prolonged survival in individual cases, with curative resection recommended as the standard treatment, in the absence of distant spread. PMID:17349340

    The saphenous vein has been the principal conduit for coronary bypass grafting from the beginning, circa 1970. This report briefly traces this history and concomitantly presents one surgeons experience and personal views on use of the vein graft. As such it is not exhaustive but meant to be practical with a modest number of references. The focus is that of providing guidance and perspective which may be at variance with that of others and recognizing that there may be many ways to accomplish ...

    Vein cava filter placement has already become one of the most effective measures for preventing pulmonary embolism which is usually secondary to deep vein thrombosis. With the development of research, non-permanent vein cava filter has been widely used. This paper aims to describe the recent progress in the research of non-permanent vein cava filters. (authors)

  2. Veins improve fracture toughness of insect wings.

    Jan-Henning Dirks

    Full Text Available During the lifetime of a flying insect, its wings are subjected to mechanical forces and deformations for millions of cycles. Defects in the micrometre thin membranes or veins may reduce the insect's flight performance. How do insects prevent crack related material failure in their wings and what role does the characteristic vein pattern play? Fracture toughness is a parameter, which characterises a material's resistance to crack propagation. Our results show that, compared to other body parts, the hind wing membrane of the migratory locust S. gregaria itself is not exceptionally tough (1.04±0.25 MPa√m. However, the cross veins increase the wing's toughness by 50% by acting as barriers to crack propagation. Using fracture mechanics, we show that the morphological spacing of most wing veins matches the critical crack length of the material (1132 µm. This finding directly demonstrates how the biomechanical properties and the morphology of locust wings are functionally correlated in locusts, providing a mechanically 'optimal' solution with high toughness and low weight. The vein pattern found in insect wings thus might inspire the design of more durable and lightweight artificial 'venous' wings for micro-air-vehicles. Using the vein spacing as indicator, our approach might also provide a basis to estimate the wing properties of endangered or extinct insect species.

  3. Subclavian vein thrombosis: A continuing challenge

    Subclavian vein thrombosis is a relatively uncommon but potentially morbid disease entity. To determine the frequency, cause, and best mode of treatment of this problem, we performed a chart review of all patients with a diagnosis of subclavian vein thrombosis at two major metropolitan hospitals during a 6-year period. A total of 40 patients were identified with subclavian vein thrombosis, which represented 3.5% of all venous thromboses detected during the 6-year period. No side or sex predilection was noted and the majority of patients were outpatients. The cause was fairly evenly divided among intravenous catheters (32%), anatomic abnormalities (45%), and carcinoma with postoperative radiation (22.5%). Despite the increasing use of the subclavian veins for pacemaker leads, hyperalimentation, and permanent intravenous access for chemotherapy, there has not been an increase in diagnosed subclavian vein thrombosis. Anatomic abnormalities with compression of the vein respond well to either heparinization or lytic therapy but require surgery if the venous abnormality persists. Treatment consisted of lytic therapy in 20%, heparinization in 55%, and elevation with removal of the central line in 25% of patients. All patients responded well to treatment, with a decrease in swelling and symptoms; no patient progressed to venous gangrene and only one (2.5%) had a documented pulmonary embolus. Medical treatment provides excellent long-term benefit in most cases unless complicated by an anatomic abnormality

  4. Transvenous liver biopsy via the femoral vein

    AIM: To study the safety, effectiveness and diagnostic value of transvenous forceps biopsy of the liver in 54 patients with coagulopathy, gross ascites or morbid obesity and suspected liver disease in whom percutaneous liver biopsy was contraindicated. MATERIAL AND METHODS: Forceps biopsy of the liver via the femoral vein was attempted in 54 adult patients with advanced liver disease of unknown aetiology who had coagulation disorders (41 cases), gross ascites (11 cases) or morbid obesity (two cases). In each patient two to six biopsies (average four) were taken using a radial jaw forceps inserted via the right or left femoral vein. RESULTS: The procedure was successful in 53 cases. Hepatic vein catheterization failed in one patient. Adequate liver tissue for diagnosis was obtained in 84% of cases. One patient developed delayed haemorrhage at 12 h from a capsular leak that was undetected during the biopsy procedure. This patient required blood transfusions and laparotomy to control bleeding. There were no deaths in the 53 patients studied. Transient minor chest and shoulder pain was encountered during sheath insertion into a hepatic vein in 23 patients. Three patients developed a femoral vein haematoma, which resolved with conservative treatment. CONCLUSION: Transvenous liver biopsy via the femoral vein is another safe, effective, simple alternative technique of biopsy when the percutaneous route is contraindicated

  6. Modified Shumacker repair of transposition of the great arteries. Surgical and angiocardiographic considerations.

    Tonkin, I L; Allen, R G; Casini, M; Marin-Garcia, J; Anthony, C L; Bell, E D; Paul, R N; Chase, N A

    1983-02-01

    Sixteen patients with transposition of the great arteries, 8 days to 2 1/2 years of age, underwent intra-atrial transposition of venous return by the modified Shumacker technique. A bipedicle flap of right atrial wall was used to direct vena caval return to the mitral valve, and a hinged viable flap of pericardium was used to form the lateral wall of the pulmonary venous pathway. Thirteen patients survived operation and are well to date. Two of the three nonsurvivors were less than 1 month of age at operation, and the third had an associated inlet ventricular septal defect and a straddling tricuspid valve. Early postoperative chest radiographs were compared with preoperative films in each patient. Postoperative findings included minor right pleural effusion in four, minor pneumothorax in two, and paralyzed right hemidiaphragm in one. Two patients required a permanent pacemaker because of the development of sick sinus syndrome 2 and 4 years postoperatively. Each preoperative angiocardiogram was reviewed and compared with postoperative studies in nine patients. The latter demonstrated absence of caval gradients in each, trivial baffle leaks in four, a moderate baffle leak in one, small residual ventricular septal defects in two, and mild tricuspid regurgitation in two patients.

  7. Cutoff for the Transposition Walk on Permutations with One-Sided Restrictions

    Blumberg, Olena

    2012-01-01

    This paper explores the mixing time of the random transposition walk on permutations with one-sided interval restrictions. In particular, we're interested in the notion of cutoff, a phenomenon which occurs when mixing occurs in a window of order smaller than the mixing time. One of the main tools of the paper is the diagonalization obtained by Hanlon; the use of the spectral information is inspired by the famous paper of Diaconis and Shahshahani on the mixing time of the random transposition walk on the entire symmetric group. The diagonalization allows us to prove chi-squared cutoff for a broad class of one-sided restriction matrices. Furthermore, under an extra condition, the walk also undergoes total variation cutoff. Finally, a large collection of examples which undergo chi-squared cutoff but in which total variation mixing occurs substantially earlier and without cutoff is produced. These results resolve a conjecture of Diaconis and Hanlon from Section 5 of Hanlon's paper.

  8. Zinc-Induced Transposition of Insertion Sequence Elements Contributes to Increased Adaptability of Cupriavidus metallidurans

    Bacteria can respond to adverse environments by increasing their genomic variability and subsequently facilitating adaptive evolution. To demonstrate this, the contribution of Insertion Sequence (IS) elements to the genetic adaptation of Cupriavidus metallidurans AE126 to toxic zinc concentrations was determined. This derivative of type strain CH34, devoid of its main zinc resistance determinant, is still able to increase its zinc resistance level. Specifically, upon plating on medium supplemented with a toxic zinc concentration, resistant variants arose in which a compromised cnrYX regulatory locus caused derepression of CnrH sigma factor activity and concomitant induction of the corresponding RND-driven cnrCBA efflux system. Late-occurring zinc resistant variants likely arose in response to the selective conditions, as they were enriched in cnrYX disruptions caused by specific IS elements whose transposase expression was found to be zinc-responsive. Interestingly, deletion of cnrH, and consequently the CnrH-dependent adaptation potential, still enabled adaptation by transposition of IS elements (ISRme5 and IS1086) that provided outward-directed promoters driving cnrCBAT transcription. Finally, adaptation to zinc by IS reshuffling can also enhance the adaptation to subsequent environmental challenges. Thus, transposition of IS elements can be induced by stress conditions and play a multifaceted, pivotal role in the adaptation to these and subsequent stress conditions. PMID:27047473

  9. Transposition anti-involution in Clifford algebras and invariance groups of scalar products on spinor spaces

    Ablamowicz, Rafal

    2011-01-01

    We introduce on the abstract level in real Clifford algebras \\cl_{p,q} of a non-degenerate quadratic space (V,Q), where Q has signature \\epsilon=(p,q), a transposition anti-involution \\tp. In a spinor representation, the anti-involution \\tp gives transposition, complex Hermitian conjugation or quaternionic Hermitian conjugation when the spinor space \\check{S} is viewed as a \\cl_{p,q}-left and \\check{K}-right module with \\check{K} isomorphic to R or R^2, C, or, H or H^2. \\tp is a lifting to \\cl_{p,q} of an orthogonal involution \\tve: V \\rightarrow V which depends on the signature of Q. The involution is a symmetric correlatio \\tve: V \\rightarrow V^{*} \\cong V and it allows one to define a reciprocal basis for the dual space (V^{*},Q). The anti-involution \\tp acts as reversion on \\cl_{p,0} and as conjugation on \\cl_{0,q}. Using the concept of a transpose of a linear mapping one can show that if [L_u] is a matrix in the left regular representation of the operator L_u: \\cl_{p,q} \\rightarrow \\cl_{p,q} relative to ...

    2015-01-01

    The diagnosis of primary pulmonary vein stenosis is often overlooked because its symptoms overlap lung diseases and pulmonary arterial hypertension. Its diagnosis may be difficult because the condition is progressive and associated with other defects. We present a case of pulmonary vein stenosis in a newborn with stenosis of the left-sided common pulmonary vein, diffuse hypoplasia of the superior right pulmonary vein, and atresia of the inferior right pulmonary vein.
