Comparison of one- and two-stage basilic vein transposition for arterio-venous fistula formation in haemodialysis patients: preliminary results  

Science.gov (United States)

Summary Objective This study aimed to compare the results of one-and two-stage basilic vein transposition (BVT) in haemodialysis patients. Methods This was a non-randomised, retrospective study between January 2007 and January 2012 on 96 patients who were diagnosed with end-stage renal failure (ESRF) (54 males, 42 females; mean age 43.6 ± 14 years) and underwent one- or two-stage BVT in our clinic. All patients who were not eligible for a native radio-cephalic or brachio-cephalic arterio-venous fistula (AVF) were scheduled for one- or two-stage BVT after arterial (brachial, radial and ulnar) and venous (basilic and cephalic) Doppler ultrasonography. Patients were retrospectively divided into two groups: group 1, basilic vein diameter > 3 mm and patients who underwent one-stage BVT; and group 2, basilic vein diameter < 3 mm and patients who underwent two-stage BVT. In group 1, the basilic vein with a single incision was anastomosed to the brachial artery, followed by superficialisation. In group 2, the basilic vein was anastomosed to the brachial artery and they underwent the superficialisation procedure one month postoperatively. Fistula maturation and postoperative complications were assessed. Results The mean diameter of the basilic vein was statistically significantly higher in group 1 (3.46 ± 0.2 mm) than in group 2 (2.79 ± 0.1 mm) (p < 0.05). In terms of postoperative complications, thrombosis, haemorrhage and haematoma were significantly higher in group 1 (34, 36 and 17%, respectively) than in group 2 (23, 14 and 6%, respectively) (p < 0.05). The rate of fistula maturation was significantly lower in group 1 (66%), compared to group 2 (77%) (p < 0.05). Time to fistula maturation was significantly shorter in group 1 (mean 41 ± 14 days), compared to group 2 (mean 64 ± 28 days) (p < 0.05). Conclusion Two-stage BVT was superior to one-stage BVT due to its lower rate of postoperative complications and higher fistula maturation, despite its disadvantage of late fistula use. Although the diameter of the basilic vein was larger in patients who underwent one-stage BVT, we observed that one-stage BVT was disadvantageous in terms of postoperative complications and fistula maturation.

Strategies for the creation and maintenance of reconstructed arteriovenous fistulas using the forearm basilic vein.  

Science.gov (United States)

Reconstruction of an arteriovenous fistula (AVF) after an initial failure to provide long-term patency has been desired in the era when hemodialysis patients' prognosis is improving. The forearm basilic vein AVF should be considered, before an artificial graft shunt or an AVF in the cubital region. The present study was designed to establish a strategy for the creation and maintenance of AVFs using the forearm basilic vein. This study reviewed 76 cases of reconstructed AVF including 18 cases using the basilic vein (23.7% of total cases). The following four points were considered: arm positioning of the cubital flexion position combined with the forearm supinated position; several small skin incisions with a subcutaneous tunnel; sufficient venous dilatation using Fogarty balloon catheter; and early percutaneous angioplasty introduction for immature AVF. The primary and secondary patency rates were examined. A radiobasilic AVF was created through a subcutaneous tunnel in two cases. The primary and secondary patency rates of AVF with the basilic vein were 54.7% and 76.7% respectively, whereas those of AVF with the cephalic vein were 49.3% and 71.3%. The basilic was not inferior to the cephalic vein (P-value of the log-rank test for primary and secondary patency rates were 0.927 and 0.811, respectively). Early stage percutaneous angioplasty was effective in five cases with immature AVF. The forearm basilic vein was useful in AVF reconstruction and equivalent to radiocephalic reconstruction. Careful observation and percutaneous angioplasty during the early period after the surgery were essential for long-term patency. PMID:24107279

A New Formula to Estimate the Length of Right Upper Extremity Vein from Elbow Crease to Carina Calculated by Peripherally Inserted Central Catheter Insertion through Right Basilic Vein Puncture  

International Nuclear Information System (INIS)

To measure the length of the upper extremity vein between the elbow crease and the carina (elbow crease to carina length, ECL), to facilitate the appropriate positioning of the tip of the peripherally inserted central catheter (PICC). A total of 124 patients (64 men and 60 women; mean age 65.2 ± 15.4 years; range, 21-90 years) inserted with PICC through the right basilic vein under fluoroscopy were included in this retrospective study. The ECL was determined as follows: ECL = (distance from elbow crease to puncture site) + (the catheter length of PICC) - (distance from carina to catheter tip on post-procedural chest radiograph). We analyzed the relationship between ECL and patient height. The mean ECL through right basilic vein was 42.07 ±4.03 cm (27.5 to 52.2 cm). ECL was found to be significantly correlated with patient height: ECL (cm) = 0.24 X patient height (cm) + 3.75. The formula developed in our study would be helpful for predicting the optimal catheter length during a blind bedside procedure of PICC via the right basilic vein.

The authors present the technique and initial results of two alternatives to portal vein reconstruction in these cases. METHODS: Three patients who suffered end stage liver disease underwent orthotopic liver transplantation. As the portal vein was inadequate in each case, the left gastric vein (two cases or the inferior mesenteric vein was isolated, tied distally, transposed and anastomosed to the donor portal vein. RESULTS: In all three cases the reperfusion was apparently satisfactory and the postoperative course was uneventful. Doppler ultrasonography and liver function tests confirmed the sufficiency of the portal flow. CONCLUSION: The left gastric vein or the inferior mesenteric vein may be a good alternative to portal reconstruction in liver transplant.

Full Text Available SciELO Chile | Language: English Abstract in spanish El recorrido del nervio cutáneo antebraquial medial (NCAM) proporciona la inervación sensorial medial del antebrazo. Su anatomía se ha descrito en parte, porque los datos relativos a su patrón de ramificación y distancias a puntos de referencia adyacentes son insuficientes. El propósito de este estu [...] dio fue proporcionar datos morfométricos sobre la anatomía del NCAM, comparando entre lados y sexos. Se disecaron 96 miembros superiores de 26 hombres y 22 mujeres. Se encontró que 5 ramos del NCAM traspasaron la fascia profunda y llegaron 4 hasta la línea interepicondilar (LIE). Presencia de 2 y 3 ramos se encontró en la mayoría de los casos (>80%). Las distancias de estos ramos a los puntos anatómicos variaron considerablemente. En caso de ausencia de ramos, la distancia medial al epicóndilo medial (EM) y arteria braquial (AB) fueron de aproximadamente 1,5 cm, mientras que a la vena basílica (VB) fueron 0,7 cm en ambos sexos. Independientemente del patrón de ramificación, el NCAM podría pasar sobre o cerca (a menos de 0,5 cm ) del EM, VB y AB. Asimetría en el patrón de ramificación se encontró en 50% de las muestras. Diferencias en algunos de los parámetros de medición se observaron según sexo, pero no por lado. Estos datos son relevantes para localizar el NCAM durante el bloqueo del nervio y la toma de injertos, sino también para evitar la lesión del nervio durante los procedimientos quirúrgicos. Abstract in english Medial antebrachial cutaneous nerve (MACN) courses in the medial arm to provide sensory innervation to the medial forearm. Its anatomy has been partly described since data regarding its branching pattern and distances to adjacent landmarks are still lacking. The purpose of this study was to provide [...] morphometric anatomy of the MACN with comparisons between sides and sexes. Ninety-six upper extremities from 26 males and 22 females were dissected. We found that up to 5 branches of MACN pierced the deep fascia with the maximum of 4 reaching the interepicondylar line (IEL). Presence of 2 and 3 branches was found in the majority of cases (> 80%). The distances from these branches to the landmarks varied considerably. In case of no branch, the mean distances to the medial epicondyle (ME) and brachial artery (BA) were approximately 1.5 cm while those to the basilic vein (BV) were 0.7 cm in both sexes. Regardless of the branching pattern, the MACN could pass over or close (within 0.5 cm) to the ME, BV and BA. Asymmetry in the branching pattern was found in 50% of specimens. Sex but not side differences were observed in some measurement parameters. These data are crucial for not only localizing the MACN during nerve block and graft harvest but also avoiding the nerve injury during surgical procedures.

Cavo-portal transposition in rat: a new simple model  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Liver transplantation in presence of diffuse portal vein thrombosis is possible by using caval blood as portal inflow, through cavo-portal transposition. However, clinical results are heterogeneous and experimental studies are needed, but similar hemodynamic conditions are difficult to obtain, especially in small animals. Herein we describe a new simple model of cavo-portal transposition in rat. Methods Spontaneous porto-systemic shunts are induced by subcutaneous transposition of the spleen. The presence of porto-caval shunts through the spleen permits the interruption of the main portal vein without splanchnic hemodynamic consequences. Cavo-portal transposition is achieved by anastomosing the inferior vena cava and the main portal vein after division of the pancreatic-duodenal vein. Results Selective angiography revealed total splanchnic blood diversion to the systemic venous circulation through the neoformed collaterals; macroscopical examination showed the absence of any signs of acute portal hypertension with normal liver and gut appearance. Conclusion This model of cavoportal transposition is simple, effective and it simulates the clinical hemodynamic condition since the porto-systemic shunts induced by splenic subcutaneous transposition correspond to the physiological inframesocolic collaterals during chronic portal thrombosis in man.

Basil (Ocimum basilicum Genetic Variability and Viral Disease Assessment in Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available The study aims at assessing Basil’s genetic phenotypic variability and viral disease incidence in Nigeria for sustainable pathological interventions. Basil (Ocimum basilicum is important for it’s medicinal and nutritive value. It is highly adaptable as a potential crop in the tropics and could therefore enhance the food security of sub Saharan Africa nations. Germplasm seed evaluation and characterization was therefore carried out from the nationwide National Horticultural Research Institute (NIHORT seed collection survey to expand NIHORT basil genetic base. The field layout was completely randomized design with five replications. The treatments were: O. basilicum, O. gratissimum and the local basil. Treatments were randomly allocated per replication. There were significant phenotypic differences in the O. basilicum variety. These differences were observed in the plant coloration ranging from deep to light purple coloration of stem, leaf, leaf vein and petiole. Our observations also revealed for the first time significant tolerance to Venial Mottle Mosaic Virus (VMMV in the purple colored compared to the green O. basilicum in the early stages of growth till 50% anthesis. This is the first report of this observation in the African continent. Tolerance to VMMV symptoms increased significantly (LSD 5% with purplish coloration. We concluded that inducement of purplish coloration in Basil through breeding might improve tolerance to VMMV and thereby increase market value of Basil with sustainable pathological interventions.

In comparative genomics, a transposition is an operation that exchanges two consecutive sequences of genes in a genome. The transposition distance between two genomes, that is, the minimum number of transpositions needed to transform a genome into another, is, according to numerous studies, a relevant evolutionary distance. The problem of computing this distance when genomes are represented by permutations is called the Sorting by Transpositions problem (SBT), and has been introduced by Bafna...

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.

Congenitally corrected transposition  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Congenitally corrected transposition is a rare cardiac malformation characterized by the combination of discordant atrioventricular and ventriculo-arterial connections, usually accompanied by other cardiovascular malformations. Incidence has been reported to be around 1/33,000 live births, accounting for approximately 0.05% of congenital heart malformations. Associated malformations may include interventricular communications, obstructions of the outlet from the morphologically left ventricle, and anomalies of the tricuspid valve. The clinical picture and age of onset depend on the associated malformations, with bradycardia, a single loud second heart sound and a heart murmur being the most common manifestations. In the rare cases where there are no associated malformations, congenitally corrected transposition can lead to progressive atrioventricular valvar regurgitation and failure of the systemic ventricle. The diagnosis can also be made late in life when the patient presents with complete heart block or cardiac failure. The etiology of congenitally corrected transposition is currently unknown, and with an increase in incidence among families with previous cases of congenitally corrected transposition reported. Diagnosis can be made by fetal echocardiography, but is more commonly made postnatally with a combination of clinical signs and echocardiography. The anatomical delineation can be further assessed by magnetic resonance imaging and catheterization. The differential diagnosis is centred on the assessing if the patient is presenting with isolated malformations, or as part of a spectrum. Surgical management consists of repair of the associated malformations, or redirection of the systemic and pulmonary venous return associated with an arterial switch procedure, the so-called double switch approach. Prognosis is defined by the associated malformations, and on the timing and approach to palliative surgical care.

Sorting by Transpositions is Difficult  

CERN Document Server

In comparative genomics, a transposition is an operation that exchanges two consecutive sequences of genes in a genome. The transposition distance, that is, the minimum number of transpositions needed to transform a genome into another, is, according to numerous studies, a relevant evolutionary distance. The problem of computing this distance when genomes are represented by permutations, called the Sorting by Transpositions problem, has been introduced by Bafna and Pevzner in 1995. It has naturally been the focus of a number of studies, but the computational complexity of this problem has remained undetermined for 15 years. In this paper, we answer this long-standing open question by proving that the Sorting by Transpositions problem is NP-hard. As a corollary of our result, we also prove that the following problem is NP-hard: given a permutation pi, is it possible to sort pi using db(pi)/3 permutations, where db(pi) is the number of breakpoints of pi?

Prevalence of tooth transposition in Greek population.  

Directory of Open Access Journals (Sweden)

Full Text Available AIM: To investigate the prevalence of tooth transposition in a sample of Greek dental patients. STUDY DESIGN: Epidemiological study. TIME AND PLACE OF ACTION: Prefecture of Drama, time period 2001-2006. MATERIALS AND METHODS: The first author examined in her private practice 2034 consecutive patients seeking dental treatment. Patients with nationality other than Greek, individuals below 13 years of age with primary or mixed dentitions, patients without panoramic radiographs, patients with syndromes, as well as those who had more than one permanent tooth missing were excluded from the initial sample. In total, 1113 patients were assessed (288 men, 825 women with a mean age of 36.1 years (range: 13.1-73.0 years. MAIN MEASUREMENTS: Tooth transposition was investigated my means of clinical examination through observation and palpation, as well as with radiographic examination using panoramic radiographs. Results were analyzed with descriptive statistics. RESULTS: In total, only one case was found with tooth transposition presenting complete bilateral transposition between canine - lateral incisor in the maxilla. The percentage of patients with tooth transposition in the total dental population examined was 0.09%. The prevalence of this phenomenon in females was 0.12%, whereas in males it was 0%. Men / women ratio was found 0:1. CONCLUSIONS: Tooth transposition in Greek population is rather rare, it is most often encountered in females and concerns mostly maxillary canines and lateral incisors.

Permanent magnet machine with windings having strand transposition  

Science.gov (United States)

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.

A mariner-Based Transposition System for Listeria monocytogenes?  

Digital Repository Infrastructure Vision for European Research (DRIVER)

In this study, we developed a new mariner-based transposition system for Listeria monocytogenes. The mariner-based system has a high rate of transposition and a low rate of plasmid retention, and transposition is very random, making it an ideal tool for high-throughput transposon mutagenesis in L. monocytogenes.

Mutagen activated transposition of AhMITE1 in peanut  

International Nuclear Information System (INIS)

Mutations have played a significant role in peanut evolution and breeding. Miniature inverted repeat transposable elements (MITEs) with preferential transposition to low copy genes have been implicated in genome evolution leading to domestication in several crops. Genomic stresses are known to activate MITE transposition. Using PCR, we checked the transposition of a peanut MITE (AhMITE1) among several mutants derived through EMS mutagenesis and ?-irradiation. AhMITE1 was found to be activated by both these mutagens and the transposition was associated with the significant morphological changes even leading to altered botanical type. Transposition of AhMITE1 was also evident among spontaneous mutants. (author)

Heuristics for the transposition distance problem.  

Science.gov (United States)

Transpositions are large-scale mutational events that occur when a block of genes moves from a region of a chromosome to another region within the same chromosome. The transposition distance problem is the minimum number of transpositions required to transform one genome into another. Recently, Bulteau et al. [Bulteau L, Fertin G, Rusu U, Automata, Languages and Programming, Vol. 6755 of Lecture Notes in Computer Science, pp. 654-665, Springer Berlin, Heidelberg, 2011] proved that finding the transposition distance is a NP-Hard problem. Some approximation algorithm for this problem have been presented to date [Bafna V, Pevzner PA, SIAM J Discr Math11(2):224-240, 1998; Elias I, Hartman T, IEEE/ACM Trans Comput Biol Bioinform3(4):369-379, 2006; Mira CVG, Dias Z, Santos HP, Pinto GA, Walter ME, Proc 3rd Brazilian Symp Bioinformatics (BSB'2008), pp. 115-126, Santo André, Brazil, 2008; Walter MEMT, Dias Z, Meidanis J, Proc String Processing and Information Retrieval (SPIRE'2000), pp. 199-208, Coruña, Spain, 2000]. Here we focus on developing heuristics to provide an improved approximated solution. Our approach outperforms other algorithms on small sized permutations. We also show that our algorithm keeps the good performance on longer permutations. PMID:24131057

Surgical transposition of the ovary: Radiologic appearance  

International Nuclear Information System (INIS)

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

Association Rule Mining by Block Scattered Transposition  

Directory of Open Access Journals (Sweden)

Full Text Available Association Rule Mining technique is used to discover the interesting association or correlation among a large set of data items. It plays an important role in generating frequent itemsets from large databases. The Association Rule Mining algorithms such as Apriori, FP-Growth requires repeated scans over the entire database. All the input/output overheads that are being generated during repeated scanning the entire database decrease the performance of CPU, memory and I/O overheads. In this paper, we have proposed An Effectual Generalized Mesh Transposition Algorithm (EGMTA for frequent itemsets generation. Our algorithm considers transactional dataset as Matrix and Block Scattered Matrix Transposition is applied on generalized transactional dataset. The CPU and I/O overhead can be reduced in our proposed algorithm and it is much faster than other Association Rule Mining algorithms.

Echocardiography of transposition of the great arteries.  

Science.gov (United States)

The successful diagnosis, surgical planning, and long-term care of children with transposition of the great arteries require high-quality cardiac imaging with echocardiography. Echocardiography must identify the relevant anatomic variants of transposition of the great arteries, such as of ventricular septal defects and aortic arch anomalies. Methodical and detailed imaging of the coronary arteries is particularly important, as translocation of the coronary arteries is a critical component of the arterial switch procedure. Familiarity with the potential coronary artery variants and the ideal imaging planes is essential for an echocardiographer. Knowledge of both the early and late complications following the arterial switch procedure is essential to optimise post-operative echocardiography. These complications can include residual lesions leading to haemodynamic compromise or progressive late phenomena, such as aortic root dilatation and aortic insufficiency. Echocardiography will continue to be the cornerstone to the lifelong management of transposition of the great arteries, and improvements in technology and increased familiarity with modalities such as stress echocardiography will enhance the role of advanced imaging even further.

Corrected transposition of the great arteries  

Energy Technology Data Exchange (ETDEWEB)

The corrected transposition of the great arteries is an usual congenital cardiac malformation, which consists of transposition of great arteries and ventricular inversion, and which is caused by abnormal development of conotruncus and ventricular looping. High frequency of associated cardiac malformations makes it difficult to get accurate morphologic diagnosis. A total of 18 cases of corrected transposition of the great arteries is presented, in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul National University Hospital between September 1976 and June 1981. The clinical, radiographic, and operative findings with the emphasis on the angiocardiographic findings were analyzed. The results are as follows: 1. Among 18 cases, 13 cases have normal cardiac position, 2 cases have dextrocardia with situs solitus, 2 cases have dextrocardia with situs inversus and 1 case has levocardia with situs inversus. 2. Segmental sets are (S, L, L) in 15 cases, and (I, D,D) in 3 cases and there is no exception to loop rule. 3. Side by side interrelationships of both ventricles and both semilunar valves are noticed in 10 and 12 cases respectively. 4. Subaortic type conus is noted in all 18 cases. 5. Associated cardic malformations are VSD in 14 cases, PS in 11, PDA in 3, PFO in 3, ASD in 2, right aortic arch in 2, tricuspid insufficiency, mitral prolapse, persistent left SVC and persistent right SVC in 1 case respectively. 6. For accurate diagnosis of corrected TGA, selective biventriculography using biplane cineradiography is an essential procedure.

Coping with EU environmental legislation : transposition principles and practices  

DEFF Research Database (Denmark)

A ‘burden reducing’ agenda has spurred an increased interest in how EU environmental legislation is transposed into national legislation—most prominently reflected in the principle of ‘no gold-plating’. Yet, an important question is to what extent transposition principles and practices may ensure a coherent and accessible body of environmental legislation, while at the same time ensuring adequate transposition of EU environmental legislation. This article analyses the existence, or emergence, of transposition principles and practices in three Member States—the United Kingdom, the Netherlands and Denmark. It also examines how EU initiatives may influence these principles and practices. The article concludes that the steering of transposition processes by general transposition principles and objectives alone, and in particular those dominated by a ‘burden reducing’ agenda, has a limited focus on coherence and accessibility with respect to environmental legislation and that such issues deserve more attention in the transposition process.

Reconstruction of permutations distorted by single transposition errors  

CERN Document Server

The reconstruction problem for permutations on $n$ elements from their erroneous patterns which are distorted by transpositions is presented in this paper. It is shown that for any $n \\geq 3$ an unknown permutation is uniquely reconstructible from 4 distinct permutations at transposition distance at most one from the unknown permutation. The {\\it transposition distance} between two permutations is defined as the least number of transpositions needed to transform one into the other. The proposed approach is based on the investigation of structural properties of a corresponding Cayley graph. In the case of at most two transposition errors it is shown that $\\frac32(n-2)(n+1)$ erroneous patterns are required in order to reconstruct an unknown permutation. Similar results are obtained for two particular cases when permutations are distorted by given transpositions. These results confirm some bounds for regular graphs which are also presented in this paper.

A research on statistical estimation of storm transposition  

Science.gov (United States)

This paper presents a systematic analysis of various methods of the statistical estimation of storm transposition and compares the results calculated using these methods with those obtained from the national isoline maps of rainfall parameters and Probable Maximum Precipitation (PMP). The paper shows that the mean value ratio method is suitable for PMP transposition but unsuitable for design storm transposition with a return period concept. On the other hand, statistical methods of storm transposition correlated with Cv, ? or Km are comparatively suitable for design storm transposition but unsuitable for PMP transposition. Special attention should be paid in choosing any of these methods. A suggested graphical method using the modulus coefficient Kp for transposing design storms is found applicable and simple.

Porto-hepatic bypass by organohepatopexy in rats with prehepatic portal hypertension. Formation of new venous porto-hepatic collaterals following omento-, jejuno-, and splenohepatopexy, and their effect on portal vein pressure.  

Science.gov (United States)

Transposition to the liver of the greater omentum; the jejunum, and the spleen in 3 groups of rats with prehepatic portal hypertension due to a calibrated portal vein stenosis with a diameter of 1.2 mm resulted in the formation of new venous collaterals from the transposed organs into the liver parenchyma. The collaterals were visualized macro- and microscopically, as well as angiographically, and were found to drain into intrahepatic branches of the portal vein, sinusoids, and hepatic veins. The portal vein pressure 8 weeks after stenosis and transposition was found to be significantly lower in rats with transposed organs than in controls. The collaterals were sufficiently well developed to significantly reduce the increase in portal vein pressure that follows acute occlusion of the portal vein and the natural splenorenal collaterals.

Effects of biocides on chlorophyll contents of detached basil leaves  

Directory of Open Access Journals (Sweden)

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.

Evaluation of in vitro antimicrobial activity of Thai basil oils and their micro-emulsion formulas against Propionibacterium acnes.  

Science.gov (United States)

The aim of this study was to evaluate the efficacy of Thai basil oils and their micro-emulsions, on in vitro activity against Propionibacterium acnes. An agar disc diffusion method was employed for screening antimicrobial activity of the essential oils of Ocimum basilicum L. (sweet basil), Ocimum sanctum L. (holy basil) and Ocimum americanum L. (hoary basil) against P. acnes. Minimum inhibitory concentration (MIC) values of the basil oils were determined using an agar dilution assay. The obtained results indicated that the MIC values of sweet basil and holy basil oils were 2.0% and 3.0% v/v, respectively, whereas hoary basil oil did not show activity against P. acnes at the highest concentration tested (5.0% v/v). Gas chromatography-mass spectrometry analysis revealed that methyl chavicol (93.0%) was the major compound in sweet basil oil, and eugenol (41.5%), gamma-caryophyllene (23.7%) and methyl eugenol (11.8%) were major compounds in holy basil oil. Hoary basil oil contained high amounts of geraniol (32.0%) and neral (27.2%) and small amounts of methyl chavicol (0.8%). The Oil-in-water (o/w) micro-emulsions of individual basil oils with concentrations corresponding to their MIC values were formulated. The stable o/w micro-emulsion system for basil oil consisted of 55.0% v/v water phase, 10.0% v/v oil phase (2.0 or 3.0% v/v sweet basil or 3.0% v/v holy basil oil plus 7.0% v/v isopropyl myristate), 29.2% v/v polysorbate 80 and 5.8% v/v 1,2-propylene glycol. Hydroxyethylcellulose at a concentration of 0.5% w/v was used as thickening agent. According to the disc diffusion assay, the formulations containing sweet basil oil exhibited higher activity against P. acnes than those containing holy basil oil, and the thickened formulations tended to give a lower activity against P. acnes than the non-thickened formulations. The prepared micro-emulsions were stable after being tested by a heat-cool cycling method for five cycles. These findings indicate the possibility to use Thai sweet and holy basil oil in suitable formulations for acne skin care. PMID:18492147

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.

Essential oil composition from twelve varieties of basil (Ocimum spp grown in Colombia  

Directory of Open Access Journals (Sweden)

Full Text Available Essential oil compositions of aerial parts from twelve basil cultivars (Ocimum spp were analysed by gas chromatography-mass spectrometry (GC-MS. Ten of them were characterized by the presence of a high percentage of methyl cinnamate (35-80%, which defined the chemotype for these varieties. Only one presented the caryophyllene chemotype and another, the linalool chemotype. Three of the basils, "purple ruffles", "little virgin" and "purple virgin" exhibited the methyl cinnamate > linalool subtype. "White compact" and "white ruffles" showed the methyl cinnamate > linalool > 1,8-cineole subtype. Methyl cinnamate > methyl eugenol was the subtype for "purple castle". The variety "large green leaves" exhibited the linalool > methyl cinnamate subtype. Caryophyllene > methyl eugenol subtype was determined for "clove basil". The rest of the basils "cinnamon", "purple lovingly", "sweet castle" and "purple long-legged", belonged to the methyl cinnamate chemotype in which methyl cinnamate constituted more than 62% of the total essential oil content.

Transposition of Domain Knowledge into Educational Games  

DEFF Research Database (Denmark)

Starting from Rogoff’s (1990) theory of apprenticeship in thinking and Apter’s (1987) reversal theory, this paper discusses the formulation of PlayDT (Playful Domain Transposition), a new approach to support the transposition of complex concepts, from different knowledge domains, into playful interactions, through the design of interactive media. PlayDT aims at facilitating the creation of a creative and easy understandable mapping between knowledge and interaction within the game. Multiple representations are encouraged, so to allow learners to express their own preferences, regarding their play experience. This study is based on reflections on three design-oriented research projects. The first one is MicroCulture (?C), a mixed-reality game, aimed at supporting learning of historical processes during guided tours in museums; it is targeted to primary school children. ?C was developed through a participatory design process, involving task-supported interviews and co-design workshops with children between 9 and 12. Among the findings, a strategy to map knowledge into interactions emerged, together with rich insights about children’s different approaches to play. In an attempt to evaluate the knowledge mapping, we designed PrimeSlaughter, a computer game aimed at supporting learning of prime numbers and factorization, for later primary and early secondary school pupils; the same domain concepts were mapped into two play styles in the game. In this study, we intend to go further in our formulation of the PlayDT approach, through another design study, aimed at creating a game to support learning of the Fourier Transform. In order to generalize further the mapping approach, a participatory workshop was conducted with university students, who provided inspirations to map the Fourier Transform into different games and various play styles. Reflections on these studies provide a solid grounding to define the PlayDT approach, its different stages, and implications for learning practice.

Transpositionally active episomal hAT elements  

Directory of Open Access Journals (Sweden)

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.

Letter transpositions within morphemes and across morpheme boundaries.  

Science.gov (United States)

Recent evidence has revealed conflicting results regarding the influence of letter transpositions during the recognition of morphologically complex words. While some studies suggest that the disruption of the morpheme boundary through across-boundary transpositions (e.g., darnkess) leads to the absence of masked transposed-letter (TL) priming, other studies have found that TL priming occurs independently of whether or not letters have been transposed across the boundary. We conducted three experiments to test whether the difference between TL- within and TL-across priming is modulated by (a) the transposition of internal versus external letters of the stem (Experiment 1), (b) the overall proportion of affixed trials (Experiment 2), or (c) the relative frequency between prime and target (Experiment 3). The results revealed equal TL-within and TL-across boundary priming across all three experiments, which adds to previous findings suggesting that across-boundary transpositions do not interfere with the recognition of morphologically complex words.

Universal platform for quantitative analysis of DNA transposition  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Completed genome projects have revealed an astonishing diversity of transposable genetic elements, implying the existence of novel element families yet to be discovered from diverse life forms. Concurrently, several better understood transposon systems have been exploited as efficient tools in molecular biology and genomics applications. Characterization of new mobile elements and improvement of the existing transposition technology platforms warrant easy-to-use assays for the quantitative analysis of DNA transposition. Results Here we developed a universal in vivo platform for the analysis of transposition frequency with class II mobile elements, i.e., DNA transposons. For each particular transposon system, cloning of the transposon ends and the cognate transposase gene, in three consecutive steps, generates a multifunctional plasmid, which drives inducible expression of the transposase gene and includes a mobilisable lacZ-containing reporter transposon. The assay scores transposition events as blue microcolonies, papillae, growing within otherwise whitish Escherichia coli colonies on indicator plates. We developed the assay using phage Mu transposition as a test model and validated the platform using various MuA transposase mutants. For further validation and to illustrate universality, we introduced IS903 transposition system components into the assay. The developed assay is adjustable to a desired level of initial transposition via the control of a plasmid-borne E. coli arabinose promoter. In practice, the transposition frequency is modulated by varying the concentration of arabinose or glucose in the growth medium. We show that variable levels of transpositional activity can be analysed, thus enabling straightforward screens for hyper- or hypoactive transposase mutants, regardless of the original wild-type activity level. Conclusions The established universal papillation assay platform should be widely applicable to a variety of mobile elements. It can be used for mechanistic studies to dissect transposition and provides a means to screen or scrutinise transposase mutants and genes encoding host factors. In succession, improved versions of transposition systems should yield better tools for molecular biology and offer versatile genome modification vehicles for many types of studies, including gene therapy and stem cell research.

Minimally invasive vein surgery.  

Science.gov (United States)

Advances in minimally invasive vein surgery (MIVS) techniques made during the last decade have decreased operative morbidity, the number and size of incisions, operative time and recovery time. The following MIVS techniques will be discussed: 1. Transilluminated Powered Phlebectomy (TIPP) TriVex. 2. Radiofrequency Ablation Greater Saphenous Vein (RFGSV) Closure. 3.Laser Ablation Greater Saphenous Vein (EVLT). 4. Subfascial Endoscopic Perforator Surgery (SEPS). 5. Percutaneous Vein Valve Bioprosthesis (PVVB) The techniques used in MIVS allow surgeons to manage venous pathophysiology associated with all three venous systems of the lower extremities. The results are comparable to those obtained with open procedures. PMID:14770249

The failed ulnar nerve transposition. Etiology and treatment.  

Science.gov (United States)

Various procedures have been recommended for the treatment of cubital tunnel syndrome. Simple decompression in situ, medial epicondylectomy, subcutaneous transposition, intramuscular transposition, and submuscular transposition all have their advocates. The results of the surgical treatment for cubital tunnel syndrome are related to the severity of the compressive neuropathy at the time of diagnosis and to the adequate decompression of the nerve at all sites of potential compression at the time of surgical treatment. Fourteen patients who had previously undergone surgical treatment for cubital tunnel syndrome were evaluated because of persistent pain, paresthesia, numbness, and motor weakness. All patients had documented persistent compression of the ulnar nerve on clinical and electromyographic evaluation. The indication for repeat surgical exploration in all patients was unremitting pain despite nonoperative treatment. All patients had been treated by neurolysis and submuscular transposition of the ulnar nerve as described by Learmonth. The causes of continued pain after initial surgery included retention of the medial intermuscular septum, dense perineural fibrosis of the nerve after intramuscular and subcutaneous transposition, adhesions of the nerve to the medial epicondylectomy site, and recurrent subluxation of the nerve over the medial epicondyle after subcutaneous transposition. Revision surgery was found to be highly successful for relief of pain and paresthesias; however, the recovery of motor function and return of sensibility were variable and unpredictable.

Vein graft failure.  

Science.gov (United States)

After the creation of an autogenous lower extremity bypass graft, the vein must undergo a series of dynamic structural changes to stabilize the arterial hemodynamic forces. These changes, which are commonly referred to as remodeling, include an inflammatory response, the development of a neointima, matrix turnover, and cellular proliferation and apoptosis. The sum total of these processes results in dramatic alterations in the physical and biomechanical attributes of the arterialized vein. The most clinically obvious and easily measured of these is lumen remodeling of the graft. However, although somewhat less precise, wall thickness, matrix composition, and endothelial changes can be measured in vivo within the healing vein graft. Recent translational work has demonstrated the clinical relevance of remodeling as it relates to vein graft patency and the systemic factors influencing it. By correlating histologic and molecular changes in the vein, insights into potential therapeutic strategies to prevent bypass failure and areas for future investigation are explored. PMID:24095042

Driving DNA transposition by lentiviral protein transduction.  

Science.gov (United States)

Gene vectors derived from DNA transposable elements have become powerful molecular tools in biomedical research and are slowly moving into the clinic as carriers of therapeutic genes. Conventional uses of DNA transposon-based gene vehicles rely on the intracellular production of the transposase protein from transfected nucleic acids. The transposase mediates mobilization of the DNA transposon, which is typically provided in the context of plasmid DNA. In recent work, we established lentiviral protein transduction from Gag precursors as a new strategy for direct delivery of the transposase protein. Inspired by the natural properties of infecting viruses to carry their own enzymes, we loaded lentivirus-derived particles not only with vector genomes carrying the DNA transposon vector but also with hundreds of transposase subunits. Such particles were found to drive efficient transposition of the piggyBac transposable element in a range of different cell types, including primary cells, and offer a new transposase delivery approach that guarantees short-term activity and limits potential cytotoxicity. DNA transposon vectors, originally developed and launched as a non-viral alternative to viral integrating vectors, have truly become viral. Here, we briefly review our findings and speculate on the perspectives and potential advantages of transposase delivery by lentiviral protein transduction. PMID:25057443

Basil Bunting’s Aesthetic Function: Art vs. Intellect  

Directory of Open Access Journals (Sweden)

Full Text Available

Basil Bunting is most commonly thought of as 1930s and 1940s poet grouped with some other poets such as Louis Zukofsky and Lorine Niedecker under the label “Objectivist ”. The present researchers seek to achieve two goals in this paper. The fi rst goal is to argue that Bunting pushes the aesthetic function to the very brink of sense but holds it there, oscillating on the cusp of referential meaning, thus creating a contested, liminal space where sound and sense content for the constructive axis of meaning-construction. The second goal is to construct an oppositional relationship between art and intellect and conclude that if the best poetry aspires to a state of pure music, that aspiration moves it even further away from the intellect1. Reference will also be made to opponents who put sight and visuality over and above everything else in man’s effort to acquire knowledge of this world in general.

Sweet basil (Ocimum basilicum L. flowering affected by foliar nitrogen application  

Directory of Open Access Journals (Sweden)

Full Text Available The aromatic and curative properties of basil are connected with the presence of essential oil, mainly in the leaves and flowers. Herb yield and the quality of basil oil are related to the effect of genetic, ontogenetic and environmental factors. In the studies conducted in the years 2008-2009, the effect of basil cultivar and foliar feeding upon selected flowering features was examined. In an unheated plastic tunnel, plants of Kasia, Wala, Genua Star and Opal cultivars were grown. Foliar feeding was done by the application of 0.5% urea solution or by spraying the plants with water. During harvest the characteristic features of flowering were determined, i.e. the number and length of inflorescences, as well as the number of verticils and flowers per inflorescence. A vast differentiation was demonstrated in flowering of sweet basil plants of the examined cultivars. The most inflorescences were formed by the plants of the Polish cultivar Kasia, compared to the remaining ones. The longest inflorescences with the highest number of flowers in the main inflorescence were found in 'Genua Star'. Foliar feeding of the plants with nitrogen caused a significant increase of inflorescence number, but it did not significantly affect the remaining features of basil flowering.

Different Points of View Concerning the Didactic Transposition  

Directory of Open Access Journals (Sweden)

Full Text Available The present article treats the concept of Didactic Transposition, taking as reference the work of Yves Chevallard, La transposición didáctica: del saber sabio al saber enseñado (2005. We compared the adduction of the concept in several works, such as thesis, dissertations and articles, and discussed the multiple impressions concerning the process of didactic transposition. These papers show that the conceptualizations are not well defined, entailing dubiousness and discussions. Some differences accrue from different areas of science, distinct of mathematics, others are inherent on the original ideas in Chevallard (2005, paper that served as bibliographical reference for the majority of the studied works.

Sorting of Permutations by Cost-Constrained Transpositions  

CERN Document Server

We address the problem of finding the minimum decomposition of a permutation in terms of transpositions with non-uniform cost. For arbitrary non-negative cost functions, we describe polynomial-time, constant-approximation decomposition algorithms. For metric-path costs, we describe exact polynomial-time decomposition algorithms. Our algorithms represent a combination of Viterbi-type algorithms and graph-search techniques for minimizing the cost of individual transpositions, and dynamic programing algorithms for finding minimum cost cycle decompositions. The presented algorithms have applications in information theory, bioinformatics, and algebra.

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.

Portal vein thrombosis (PVT) is a rare event in the general medical setting that commonly complicates cirrhosis with portal hypertension, and can also occur with liver tumors. The diagnosis is often incidental when a thrombus is found in the portal vein on imaging tests. However, PVT may also present with clinical symptoms and can progress to life-threatening complications of ischemic hepatitis, liver failure, and/or small intestinal infarction. This article reviews the pathophysiology of this disorder, with a major focus on PVT in patients with cirrhosis, and presents detailed guidelines on optimal diagnostic and therapeutic strategies.

Protective effect of basil (Ocimum basilicum L.) against oxidative DNA damage and mutagenesis.  

Science.gov (United States)

Mutagenic and antimutagenic properties of essential oil (EO) of basil and its major constituent Linalool, reported to possess antioxidative properties, were examined in microbial tests. In Salmonella/microsome and Escherichia. coli WP2 reversion assays both derivatives (0.25-2.0 microl/plate) showed no mutagenic effect. Salmonella. typhimurium TA98, TA100 and TA102 strains displayed similar sensitivity to both basil derivatives as non-permeable E. coli WP2 strains IC185 and IC202 oxyR. Moreover, the toxicity of basil derivatives to WP2 strains did not depend on OxyR function. The reduction of t-BOOH-induced mutagenesis by EO and Linalool (30-60%) was obtained in repair proficient strains of the E. coli K12 assay (Nikoli?, B., Stanojevi?, J., Miti?, D., Vukovi?-Gaci?, B., Knezevi?-Vukcevi?, J., Simi?, D., 2004. Comparative study of the antimutagenic potential of vitamin E in different E. coli strains. Mutat. Res. 564, 31-38), as well as in E. coli WP2 IC202 strain. EO and Linalool reduced spontaneous mutagenesis in mismatch repair deficient E. coli K12 strains (27-44%). In all tests, antimutagenic effect of basil derivatives was comparable with that obtained with model antioxidant vitamin E. Linalool and vitamin E induced DNA strand breaks in Comet assay on S. cerevisiae 3A cells, but at non-genotoxic concentrations (0.075 and 0.025 microg/ml, respectively) they reduced the number of H(2)O(2)-induced comets (45-70% Linalool and 80-93% vitamin E). Obtained results indicate that antigenotoxic potential of basil derivatives could be attributed to their antioxidative properties. PMID:17980946

Seed Germination and Early Growth Responses of Hyssop, Sweet Basil and Oregano to Temperature Levels  

Directory of Open Access Journals (Sweden)

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.

Comparison of microbial diversity of edible flowers and basil grown with organic versus conventional methods.  

Science.gov (United States)

The consumption and use of edible flowers as food is growing; however, no study has been conducted to evaluate their role in the cause of food-borne illness or in food safety. Recent food-borne outbreaks traced to fresh herbs have raised concern about their processing and handling. Basil, one of the most commonly used fresh herbs, has been identified as a source of food-borne illness. Baseline assessments of microflora were performed, and the microbial diversity between growing methods (organic vs. conventional) was compared. DNA sequencing was used to identify the microbial flora present on fresh edible flower and basil samples. The most predominant species identified were Enterobacter hormaechei (10%), Acinetobacter calcoaceticus (10%), Enterobacter ludwigii (10%), Enterobacter asburiae (6%), and Enterobacter cowanii (6%). Pseudomonas aeruginosa (6%), Salmonella enterica (6%), and Bacillus amyloliquefaciens (2%) were also isolated. Phylogenetic analysis showed that most species of isolated bacteria belonged to the phyla Gammaproteobacteria (81.2%) and Firmicutes (18.8%). Statistical analysis, diversity index for species richness, and lineage-per-time plots showed that for basil, organically grown samples had a higher microbial diversity than conventionally grown samples. Edible flowers and basil are often grown using organic methods and are commonly consumed raw without any washing or cooking, to preserve aesthetic value, but these practices may pose a potential risk for food-borne illness. The baseline assessment, together with phylogenetic and statistical analyses, indicated possible microbial contamination in edible flowers and basil. The use of statistical estimation of molecular diversity based on the 16S rRNA sequences and lineage-per-time plots with phylogenetic analysis well served as a means for comparing microbial diversity in food samples between the growing methods (organic vs. conventional).

Obstruction of superior vena cava following the Mustard operation of transposition of great arteries  

International Nuclear Information System (INIS)

The obstruction of the superior vena cava is a frequent late complication of the Mustard operation of the transposition of great arteries. Although it is asymptomatic, it threatens the patient as intracranial hypertension develops. Radionuclide angiocardiography can visualize the collateral blood flow from the obturated vena cava superior by the system of the azygos and hemiazygos veins into inferior vena cava. The benefit of this noninvasive method for screening obstruction was tested in a group of 94 patients. The obstruction of the vena cava superior was apparent in 11 patients (11.7%). In all cases, the diagnosis was confirmed by catheterization and angiocardiography. Pulsed Doppler echocardiography proved an abnormal flow in the vena cava superior in 9 patients. In other five patients with abnormal flow, obstruction was not revealed by radionuclide angiocardiography. Radionuclide angiocardiography supplements echocardiography also as regards other late complications and can be thus recommended for routine examinations of patients after the Mustard operation.

Beware the Anomalous Portal Vein  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Portal vein thrombosis is an unusual potential complication of liver resection. In our case it was due to ligation of the right branch of the portal vein during right hepatectomy in a patient without portal vein bifurcation. Hepatic angiography can delineate this abnormality and influence the choice of surgical management.

Collateral veins in left renal vein stenosis demonstrated via CT  

International Nuclear Information System (INIS)

Twelve patients with left renal vein stenosis from tumor compression were studied with CT. All had distended collateral veins in the perirenal space which either formed a radiating or a cobweb pattern or appeared as marked longitudinal veins. Inferior phrenic vein branches were seen in seven patients and were considerably enlarged in two. Other major veins possibly taking part in collateral circulation could not be recognized due to obliteration of fat planes. The renal fascia was thickened in eleven patients, probably due to edema. A close study of the perirenal space with CT may give valuable information about collateral development. (orig.)

Repellent Activities of the Essential Oils of Four Sudanese Accessions of Basil (Ocimum basilicum L. Against Anopheles Mosquito  

Directory of Open Access Journals (Sweden)

Full Text Available Basil (Ocimum basilicum L. of the Labiatae is an important culinary herb and essential oil source widely recognized worldwide, though much less in Sudan. The essential oil of 4 basil accessions were assessed for mosquito repellency were suggested. Basil seed accessions were collected as seeds and grown at the University of Gezira farm, Wad Medani, Sudan. All four essential oil conferred complete mosquito repellency (assayed by the human-bait technique lasting for 1.5 to 2.5 h per one application of 0.1 mL to a volunteer’s arm. Repellency generally decreased with bioassay time. The experimental results obtained from this study suggest that essential oil of basil are promising as repellents at 0.1% concentration against Anopheles mosquito and could be useful in the search for new natural repellent compounds.

Surgical Preparation of a Permanent Carotid Transposition in Sheep  

Directory of Open Access Journals (Sweden)

Full Text Available In large animal research, when frequent sampling of arterial blood is needed, the carotid artery transposition is the most used technique. The objective of this paper is to describe a new technique for carotid artery transposition in sheep and evaluate its effectiveness using the echo-Doppler ultrasound. The animals enrolled in this study had their carotid surgically elevated to the subcutaneous level, by suturing underneath muscles sternocephalic and brachiocephalic. None of the animals that underwent the procedure in this study had trans- or postoperative complications. Six months after the suture removal, all animals presented patent ca-rotids by echo-Doppler ultrasound. This is an easy and safe procedure for carrying out experiments that re-quire the collection of arterial blood.

New bounds and tractable instances for the transposition distance  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The problem of sorting by transpositions asks for a sequence of adjacent interval exchanges that sorts a permutation and is of the shortest possible length. The distance of the permutation is defined as the length of such a sequence. Despite the apparently intuitive nature of this problem, introduced in 1995 by Bafna and Pevzner, the complexity of both finding an optimal sequence and computing the distance remains open today. In this paper, we establish connections between two different graph...

Revisiting letter transpositions within and across morphemic boundaries.  

Science.gov (United States)

Early morphological decomposition of complex words has been supported by evidence showing that the magnitude of masked transposed-letter (TL) priming effects is greater for within-morpheme transpositions than for between-morpheme transpositions. However, these findings have lately been called into question, and a recent article by Sánchez-Gutiérrez and Rastle (Psychonomic Bulletin & Review, 20, 988-996, 2013) suggested that the above-mentioned interaction could have been the consequence of a false positive (i.e., a Type I error). Considering recent evidence showing that morpho-orthographic interactions are highly sensitive to individual differences in reading skills, we explored whether participants' averaged reading speeds were responsible for modulating the size of within- versus between-morpheme TL priming effects. A large-scale lexical decision experiment with a set of 420 suffixed Spanish words (N = 80 participants) was run using the masked-priming technique. The results revealed that individual differences modulated the magnitude of the masked TL priming effect between morphemes: Faster readers (but not slower readers) yielded greater TL priming for within- than for between-morpheme transpositions. The present data help reconcile previous divergent data by showing that faster readers revealed a morpho-orthographic interaction, whereas slower readers may rely more on a morphological-processing strategy that is not sensitive to morpho-orthographic interactions.

Cerebral vein thrombosis.  

Science.gov (United States)

The estimated annual incidence of cerebral vein thrombosis (CVT) is 3 to 4 cases per million in adults and 7 cases per million in neonates. Among the commonest risk factors there are oral contraceptive use, pregnancy and puerperium that make CVT more frequent in women than in men. Cerebral tumors, infections and traumas are less encountered local risk factors. In 15-20% of patients CVT remains unprovoked. Coagulation abnormalities causing thrombophilia, as well as hyperhomocysteinemia, are worthy to be investigated in patients with CVT. Rarely CVT can be the first clinical manifestation of a myeloproliferative neoplasm. The recurrence rate of CVT is low, but venous thromboembolism in the common sites (lower-limb deep vein thrombosis or pulmonary embolism) can recur, particularly in patients with a first idiopathic CVT. Early diagnosis and anticoagulant treatment reduce morbidity of CVT and improve survival, although the optimal duration of anticoagulant treatment is not well established. PMID:23452743

Portal vein thrombosis  

Directory of Open Access Journals (Sweden)

Full Text Available Acute portal vein thrombosis (PVT is un uncommon disease that can be seen in the Emergency Department. In the emergency department setting the diagnosis is difficult because of the variety of clinical presentation but in some clinical presentation patterns the diagnosis should be suspected. Regard to the appropriate radiological abdominal images, color flow Doppler ultrasonography can diagnose the fresh thrombus and spiral CT may be complementary in the diagnosis. The diagnosis differentiation between acute and chronic portal vein thrombosis is important for therapeutic management and prognosis. In stable patient the most common therapy is heparin and warfarin but in some cases thrombolysis can be the treatment of choice. In the patients with intestinal infarction the surgical therapy is strongly indicated. Two cases , one of acute and the other of chronic PVT, are presented and discussed.

Pelvic Vein Embolisation in the Management of Varicose Veins  

International Nuclear Information System (INIS)

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 sjugular approach is a safe and effective technique in the treatment of pelvic vein reflux.

Formation of veins  

International Nuclear Information System (INIS)

Formation of a vein requires a tension fracture to collect and pass a solution, and also precipitation therein of a solid. Uranium veins favour hydraulic openings, and deposits are in competent formations or even competent members of an incompetent series. Provenance of uranium to the solution may be by juvenile or magmatic agencies but uranium is provided to many of the large deposits by local sources. Most often initial mobilization of the uranium from the source is under magmatic influence, but this is enriched later and recurrently by deep groundwater. Precipitation of quadrivalent uranium is under conditions of increasing eH, decreasing pH, and lowered alkali content; this occurs in most vein deposits by reduction of elements in the wall-rock, and absorption of alkali into alteration minerals: Enrichment is attained often through oxidation of the hypogene solution by lateral infiltration of supergene solutions. The pathological study of developed deposits, both large and insignificant, is used to evolve suggestions pertinent to selection of search areas, generate rational expectation of either constancy or orderly change in a deposit, and to warn against distracting occurrences.

Neuroanatomical correlates of musical transposition in adolescents: A longitudinal approach  

Directory of Open Access Journals (Sweden)

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 predisposition.

Chemical Analysis of Flaxseed, Sweet Basil, Dragon Head and Quince Seed Mucilages  

Directory of Open Access Journals (Sweden)

Full Text Available Mucilage, a complex carbohydrate with a great capacity to absorb water, should be considered a potential source of industrial hydrocolloid.To examine moisture, dry weight, yield, ash and protein content, mucilaginous material were extracted from seeds by mixing the seeds with distilled water (1:20 w/v, stirring the seed-water mixtures for 3 h at 75�C, separating the mucilage extract from the seeds by filtration through a muslin and were precipitated with 3 times its volumes of 96% ethanol. The precipitates were separated by centrifugation (6500 rpm, 15 min. The data were analyzed by one-way ANOVA and Tukey test and compared in one significant levels of p< 0.05. The linseed mucilage had 4.57% moisture, 95.43% dry weight, 8.6% yield, 5.8% ash and 12.3% protein. The basil mucilage had 4.86% moisture, 95.14% dry weight, 2.07% yield, 0.84% ash and 10.9% protein. The dragon head mucilage had 4.93% moisture, 95.06% dry weight, 1.88% yield, 0.28% ash and 45.7% protein. The quince mucilage had 4.38% moisture, 95.62% dry weight, 10.9% yield, 8.24% ash and 20.9% protein. Results showed significant differences in yield mucilage content between flaxseed and quince with together and with basil and dragon head. Significant differences in ash content were observed between flaxseed and quince with basil and dragon head. The dragon head had significant difference in protein content with flaxseed, basil and quince.

Robustness of entangled states that are positive under partial transposition  

CERN Document Server

We study robustness of bipartite entangled states that are positive under partial transposition (PPT). It is shown that almost all PPT entangled states are unconditionally robust, in the sense, both inseparability and positivity are preserved under sufficiently small perturbations in its immediate neighborhood. Such unconditionally robust PPT entangled states lie inside an open PPT entangled ball. We construct examples of such balls whose radii are shown to be finite and can be explicitly calculated. This provides a lower bound on the volume of all PPT entangled states. Multipartite generalization of our constructions are also outlined.

Retalho venoso unipediculado transposto comparado ao não transposto: estudo experimental em coelhos Evaluation of unipediculated venous flap with and without transposition  

Directory of Open Access Journals (Sweden)

Full Text Available Retalhos venosos são aqueles que apresentam em seu pedículo apenas uma veia, diferente dos retalhos convencionais que são caracterizados por entrada de sangue arterial e saída de sangue venoso. O objetivo deste trabalho foi determinar se a transposição do retalho venoso unipediculado modifica a sua área de sobrevida e vascularização. As orelhas de oito coelhos foram submetidas à realização de retalhos venosos. Dissecou-se um retalho de pele de dois por dois centímetros baseado no pedículo distal da veia marginal anterior. Os retalhos foram divididos em dois grupos: no grupo I(n=8, os retalhos venosos foram levantados e suturados na mesma posição; no grupo II (n=8, os retalhos foram levantados e transpostos 90 graus. Estes dois grupos foram comparados entre si e ao grupo III(n=8, no qual foi realizado enxerto de pele com subcutâneo sobre um leito bem vascularizado. A área média de necrose no grupo I (6,5% foi significativamente menor que no grupo II (43,75%, e as áreas de necrose dos grupos I e II foram significativamente menor do que no grupo III (88,75%.

Deployment of municipal solid wastes as a substitute growing medium component in marigold and basil seedlings production.  

Science.gov (United States)

The possible use of municipal solid waste compost (MSWC) in the production of marigold and basil seedlings examined. Six medium prepared from commercial peat (CP) and MSWC (0, 15, 30, 45, 60, and 100% v/v). There was not any plant growth when MSWC used alone (100%). The addition of MSWC in low content (15% and 30%) improved seed emergence for marigold and basil respectively, while greater content revealed opposed impacts. Mean emergence time delayed as MSWC content increased into substrates. Addition of MSWC (especially in content greater than 30%) into CP reduced (from 34 to 64%) plant height, leaf number and stem diameter as a consequence reduced plant fresh weight (plant biomass) for both species. The number of lateral stems decreased (up to 81%) in basil when MSWC added into substrate mixtures. Chlorophyll b content decreased (up to 58%) in substrates with MSWC content greater than 15% or 30% while similar reduction observed in content of Chlorophyll a and total carotenoids for basil with MSWC > 60%. However, Chlorophyll a and total carotenoids content increased as MSWC content increased for marigold. K and Na leaf content increased but P equivalent decreased as MSWC content increased. Nursery-produced basil and marigold seedlings grown in 15% MSWC; displayed quality indices similar to those recorded for conventional mixtures of peat and may act as component substitute.

A phase transition in the random transposition random walk  

CERN Document Server

Our work is motivated by Bourque and Pevzner's (2002) simulation study of the effectiveness of the parsimony method in studying genome rearrangement, and leads to a surprising result about the random transposition walk on the group of permutations on $n$ elements. Consider this walk in continuous time starting at the identity and let $D_t$ be the minimum number of transpositions needed to go back to the identity from the location at time $t$. $D_t$ undergoes a phase transition: the distance $D_{cn/2} \\sim u(c)n$, where $u$ is an explicit function satisfying $u(c)=c/2$ for $c \\le 1$ and $u(c)1$. In other words, the distance to the identity is roughly linear during the subcritical phase, and after critical time $n/2$ it becomes sublinear. In addition, we describe the fluctuations of $D_{cn/2}$ about its mean in each of the three regimes (subcritical, critical and supercritical). The techniques used involve viewing the cycles in the random permutation as a coagulation-fragmentation process and relating the behav...

Qualitative radionuclide angiocardiography in the diagnosis of corrected transposition.  

Science.gov (United States)

Seven patients with corrected transposition were studied by qualitative radionuclide angiocardiography. In four patients with situs solitus with apex on the left, the pulmonary artery was in a medial and posterior position, to the right of the aorta, with its root attached to the morphological left ventricle positioned on the right. The aorta arose from the ventricle placed on the left and had an anterior position. The ventricle located on the right has a triangular shape. In the case of situs solitus with dextroversion, the pulmonary artery was to the right of the aorta and had a right-to-left direction. The ventricle placed on the right was ovoid. In one single case of situs inversus with levoversion, the pulmonary artery was on the left, emerging from the morphological left ventricle placed on the left, and was ovoid in shape, while the aorta was on the right arising from the morphological right ventricle. In one case of situs inversus with dextrocardia, atrioventricular relationships were the same as in levoversion but the apex was on the right and the morphological left ventricle was triangular. Qualitative radionuclide angiocardiography is a simple and non-invasive method for obtaining morphological data for the precise diagnosis of corrected transposition. PMID:760444

The conduction system in corrected transposition with situs inversus.  

Science.gov (United States)

The location and course of the conduction system were investigated by serial section in two hearts with corrected transposition of the great arteries in situs inversus. In the first case, characterized by dextrocardia, the interventricular septum was intact, while in the second case with levocardia, a high ventricular septal defect was associated with pulmonary atresia. In both hearts, a regular posterior connecting AV node was present, left-sided in one case and right-sided in the other. The bundle branches were distributed in the morphologically appropriate ventricles. Extensive hemorrhage and coagulation necrosis of the common bundle and bundle branches were observed in the first case, being consequent upon surgical replacement of the right-sided tricuspid valve. The common bundle ran below the membranous septum in this case. In the heart with ventricular septal defect it was related to the postero-inferior rim of the defect. In both cases, an accessory AV node was located anteriorly in the interatrial septum but did not connect with the ventricular musculature. The different position of the atrioventricular conducting tissue in corrected transposition, between cases in situs solitus and situs inversus, is emphasized. PMID:923624

Anomalous intrapulmonal vein drainage and pulmonary vein connection in DSA  

Energy Technology Data Exchange (ETDEWEB)

Anomalous pulmonary venous drainage can be detected and evaluated by angiographic studies. Now that intravenous DSA is available, this method can be used to demonstrate pulmonary venous return. This study presents the results of DSA examination in three patients having anomalous pulmonary vein connection with the left innominate vein and the superior vena cava respectively. In a fourth patient, intra-pulmonary atypical venous return could be demonstrated by DSA without anomalous connection. This minimal invasive procedure is diagnostically useful in anomalies of pulmonary veins when recommended post-processing techniques are evaluated, particularly in patients with additional cardiac septal defects.

A Study of the Essential Oils of Four Sudanese Accessions of Basil (Ocimum basilicum L. Against Anopheles Mosquito Larvae  

Directory of Open Access Journals (Sweden)

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.

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

Science.gov (United States)

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.

Vein matching using artificial neural network in vein authentication systems  

Science.gov (United States)

Personal identification technology as security systems is developing rapidly. Traditional authentication modes like key; password; card are not safe enough because they could be stolen or easily forgotten. Biometric as developed technology has been applied to a wide range of systems. According to different researchers, vein biometric is a good candidate among other biometric traits such as fingerprint, hand geometry, voice, DNA and etc for authentication systems. Vein authentication systems can be designed by different methodologies. All the methodologies consist of matching stage which is too important for final verification of the system. Neural Network is an effective methodology for matching and recognizing individuals in authentication systems. Therefore, this paper explains and implements the Neural Network methodology for finger vein authentication system. Neural Network is trained in Matlab to match the vein features of authentication system. The Network simulation shows the quality of matching as 95% which is a good performance for authentication system matching.

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

An epistemological perspective on the didactical transposition of Gaia theory  

Directory of Open Access Journals (Sweden)

Full Text Available This paper is part of larger scope project in which the scientificity of the Gaia theory is analysed, intending to contribute towards a critical appraisal or the role that such a theory might have in biology teaching and in approaching the "environment" transversal theme. The Gaia theory proposes that the biosphere acts as na adaptative control system, keeping the earth in homeostasis. Some authors have proposed that this theory should be incorporated in the school curriculum. In Brazil, it already appears in some biology textbooks. The scientificity of this theory is questioned in this paper, given that its didactical transposition should be suported by a previous demonstration of its scientific nature.

Transposase concentration controls transposition activity: myth or reality?  

Science.gov (United States)

Deciphering the mechanisms underlying the regulation of DNA transposons might be central to understanding their function and dynamics in genomes. From results obtained under artificial experimental conditions, it has been proposed that some DNA transposons self-regulate their activity via overproduction inhibition (OPI), a mechanism by which transposition activity is down-regulated when the transposase is overconcentrated in cells. However, numerous studies have given contradictory results depending on the experimental conditions. Moreover, we do not know in which cellular compartment this phenomenon takes place, or whether transposases assemble to form dense foci when they are highly expressed in cells. In the present review, we focus on investigating the data available about eukaryotic transposons to explain the mechanisms underlying OPI. Data in the literature indicate that members of the IS630-Tc1-mariner, Hobo-Ac-Tam, and piggyBac superfamilies are able to use OPI to self-regulate their transposition activity in vivo in most eukaryotic cells, and that some of them are able to assemble so as to form higher order soluble oligomers. We also investigated the localization and behavior of GFP-fused transposases belonging to the mariner, Tc1-like, and piggyBac families, investigating their ability to aggregate in cells when they are overexpressed. Transposases are able to form dense foci when they are highly expressed. Moreover, the cellular compartments in which these foci are concentrated depend on the transposase, and on its expression. The data presented here suggest that sequestration in cytoplasmic or nucleoplasmic foci, or within the nucleoli, might protect the genome against the potentially genotoxic effects of the non-specific nuclease activities of eukaryotic transposases.

Transposition of great arteries: new insights into the pathogenesis.  

Science.gov (United States)

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. In lateralization defects TGA is frequently associated with asplenia syndrome. Moreover, TGA is rather frequent in cases of isolated dextrocardia with situs solitus, showing link with defect of visceral situs. 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 humans, some families, beside TGA cases, present 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. PMID:24400257

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.

ANALYSIS OF THE ESSENTIAL OILS OF TWO DIFFERENT CULTIVATED BASIL ( OCIMUM BASILICUM L. FROM INDIA  

Directory of Open Access Journals (Sweden)

Full Text Available ABSTRACT: The chemical compositions of the essential oils of Ocimum basilicum L. cv. purple and Ocimum basilicum L. cv. green cultivated in India were investigated by GC-MS. Twenty constituents (98.5% of the total oil were identified in the volatile oil of O. basilicum L. cv. Purple. The main constituents found in the oil were methyl chavicol (52.4%, linalool (20.1%, epi-?-cadinol (5.9% and trans-?-bergamotene (5.2%. In the volatile oil of O. basilicum L. cv. green, twelve components were characterized representing 99.4% of the total oil. Methyl chavicol (40.5%, geranial (27.6%, neral (18.5% and caryophyllene oxide (5.4% were the major components. Methyl chavicol is the dominant constituent in each of the two oils. Although the oil of green basil was characterized by a high content (46.1% of citral (neral and geranial, citral was not detected in the oil of purple basil oil.

The potential of use basil and rosemary essential oils as effective antibacterial agents.  

Science.gov (United States)

The considerable therapeutical problems of persistent infections caused by multidrug-resistant bacterial strains constitute a continuing need to find effective antimicrobial agents. The aim of this study was to demonstrate the activities of basil (Ocimum basilicum L.) and rosemary (Rosmarinus officinalis L.) essential oils against multidrug- resistant clinical strains of Escherichia coli. A detailed analysis was performed of the resistance of the drug to the strains and their sensitivity to the tested oils. The antibacterial activity of the oils was tested against standard strain Escherichia coli ATCC 25922 as well as 60 other clinical strains of Escherichia coli. The clinical strains were obtained from patients with infections of the respiratory tract, abdominal cavity, urinary tract, skin and from hospital equipment. The inhibition of microbial growth by both essential oils, presented as MIC values, were determined by agar dilution. Susceptibility testing to antibiotics was carried out using disc diffusion. The results showed that both tested essential oils are active against all of the clinical strains from Escherichia coli including extended-spectrum ?-lactamase positive bacteria, but basil oil possesses a higher ability to inhibit growth. These studies may hasten the application of essential oils in the treatment and prevention of emergent resistant strains in nosocomial infections. PMID:23921795

Palm Vein Verification Using Gabor Filter  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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...

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

LENUS (Irish Health Repository)

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.

Unexpectedly rapid IS1 transposition into an Arabidopsis chromatin remodeling gene.  

Science.gov (United States)

Common cloning is often associated with instability of certain classes of DNA. Here we report on IS1 transposition as possible source of such instability. During the cloning of Arabidopsis thaliana gene into commercially available vector maintained in widely used Escherichia coli host the insertion of complete IS1 element into the intron of cloned gene was found. The transposition of the IS1 element was remarkably rapid and is likely to be sequence-specific. The use of E. coli strains that lower the copy number of vector or avoiding the presence of the problematic sequence is a solution to the inadvertent transposition of IS1. The transposition of IS1 is rare but it can occur and might confound functional studies of a plant gene. PMID:23430589

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...

Absence of retromandibular vein associated with atypical formation of external jugular vein in the parotid region.  

Science.gov (United States)

Veins of the head and neck exhibiting anatomical variations or malformations are clinically significant. Anatomical variation in the external jugular vein is very common. However, anatomical variation in the retromandibular vein is rare. In this paper, we report a rare case of complete absence of the retromandibular vein. In the absence of the retromandibular vein, the maxillary vein divided into anterior and posterior divisions. The posterior division joined the superficial temporal vein to form an atypical external jugular vein, and the anterior division joined the facial vein to form an anonymous vein. In clinical practice, radiologists and surgeons use the retromandibular vein as a guide to expose the branches of the facial nerve during superficial parotidectomy. Therefore, absence of the retromandibular vein is a hurdle during this procedure and may affect the venous drainage pattern from the head and neck. PMID:24987551

Authentication of organically and conventionally grown basils by gas chromatography/mass spectrometry chemical profiles.  

Science.gov (United States)

Basil plants cultivated by organic and conventional farming practices were accurately classified by pattern recognition of gas chromatography/mass spectrometry (GC/MS) data. A novel extraction procedure was devised to extract characteristic compounds from ground basil powders. Two in-house fuzzy classifiers, i.e., the fuzzy rule-building expert system (FuRES) and the fuzzy optimal associative memory (FOAM) for the first time, were used to build classification models. Two crisp classifiers, i.e., soft independent modeling by class analogy (SIMCA) and the partial least-squares discriminant analysis (PLS-DA), were used as control methods. Prior to data processing, baseline correction and retention time alignment were performed. Classifiers were built with the two-way data sets, the total ion chromatogram representation of data sets, and the total mass spectrum representation of data sets, separately. Bootstrapped Latin partition (BLP) was used as an unbiased evaluation of the classifiers. By using two-way data sets, average classification rates with FuRES, FOAM, SIMCA, and PLS-DA were 100 ± 0%, 94.4 ± 0.4%, 93.3 ± 0.4%, and 100 ± 0%, respectively, for 100 independent evaluations. The established classifiers were used to classify a new validation set collected 2.5 months later with no parametric changes except that the training set and validation set were individually mean-centered. For the new two-way validation set, classification rates with FuRES, FOAM, SIMCA, and PLS-DA were 100%, 93%, 97%, and 100%, respectively. Thereby, the GC/MS analysis was demonstrated as a viable approach for organic basil authentication. It is the first time that a FOAM has been applied to classification. A novel baseline correction method was used also for the first time. The FuRES and the FOAM are demonstrated as powerful tools for modeling and classifying GC/MS data of complex samples, and the data pretreatments are demonstrated to be useful to improve the performance of classifiers.

Anatomical variations of the saphenous vein arc.  

Directory of Open Access Journals (Sweden)

Full Text Available There are many anatomical variations presented by the tributaries of the saphenous vein at the saphenous – femoral junction .In anatomical texts, they are plotted as usual tributaries to the femoral vein, presentations that are not found during routine surgical practice. Knowledge of the sapheno- femoral vein junction is imperative for the surgeon when operating the venous system of lower limbs, in order to avoid accidents and prevent intraoperative varicose recurrences. The aim of the present paper is to demonstrate which of the anatomical variations of the arc of the great saphenous vein is shown more often, contributing to the description of the anatomy of the region and its name in the anatomical terminology. The present work is based on experience of one hundred dissections (n = 100 of the femoral inguinal region in human cadavers fixed with formol aqueous solution of 5% v / v, twenty (n = 20 of which were filled with latex via endovascular before its fixation. The basic scheme of the arc of the great saphenous vein receives the following tributaries: the superficial circumflex iliac vein, superficial epigastric vein [subcutaneous abdominal vein], external pudendal veins, accessory vein of the thigh [dorsal thigh], inter saphenous vein [Giacomini vein]. Inter saphenous vein was observed [Giacomini vein] in a large percentage of the sample (66%. On 77% of the cases, a single saphenous trunk was found, 22% of duplication and triplication 1%. Exceptionally small caliber veins reach the common femoral vein on its inner side, draining the pudendal region, may correspond to the third vein pudendal described by Vilanova, or a tributary of the arc that ends in isolation while the rest of the arc remains on the basic disposition. Successful surgery of the saphenous vein arc is based on an optimal anatomical knowledge of the sapheno - femoral junction, its anatomical variations and relationships.

Small veins: A big future  

International Nuclear Information System (INIS)

Using the data base developed during Phase I of IUREP (International Uranium Resources Evaluation Project, 1978, NEA/IAEA), the authors have estimated that between 0.5 million and 1.3 million tonnes of the world's speculative resources (excluding countries with centrally planned economies) could occur in vein deposits and have identified those countries in which these deposits are likely to occur. The contribution of 'small veins' to the total speculative resources is probably less than that made by other major deposit types and is significantly less than that made by deposits of the Proterozoic unconformity-related type. However, several factors favour the exploration for, and exploitation of, these deposits compared with the larger deposits, and it is concluded that small veins will play an appreciable role in meeting future uranium demands.

Optimisation of microencapsulation of holy basil essential oil in gelatin by response surface methodology.  

Science.gov (United States)

To protect holy basil essential oil (HBEO) from volatilisation and oxidation, microencapsulation by simple coacervation of gelatin was developed. An optimal encapsulating condition obtained from response surface methodology (RSM) was a gelatin concentration of 11.75% (w/v) and an HBEO amount of 31ml, which provided the greatest yield, oil content, and encapsulation efficiency of 98.80%, 66.50%, and 95.41%, respectively. Scanning electron microscope (SEM) revealed that the internal surface of the microcapsule was honeycomb-like networks containing nonhomogeneous distributions of HBEO. Fourier transform infrared spectroscopy (FTIR) indicated that there was no significant interaction between the HBEO and gelatin. Under storage conditions at 60°C for 49days equivalent to 25°C for 18months, small decreases in the HBEO retention rate and the antioxidant activity were observed. Thus, the microencapsulated formulation has potential to be applied to other volatile compounds. PMID:24360456

Chemical composition and antimicrobial properties of different basil essential oils chemotypes from Togo  

Directory of Open Access Journals (Sweden)

Full Text Available 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; t-anethole 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 to 150 µl.l-1 and from 200 to 500 µl.l-1 respectively. Likewise, on tested bacteria the MIC varied from 200 µl.l-1 to 400 µl.l-1 and from 250 to 500 µl.l-1 respectively. These findings are supportive of the potential of both basil oil chemotypes for use as active ingredients in natural antibiotic drugs.

Gain-of-Function Mutations in Tnsc, an Atp-Dependent Transposition Protein That Activates the Bacterial Transposon Tn7  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The bacterial transposon Tn7 encodes five genes whose protein products are used in different combinations to direct transposition to different types of target sites. TnsABC+D directs transposition to a specific site in the Escherichia coli chromosome called attTn7, whereas TnsABC+E directs transposition to non-attTn7 sites. These transposition reactions can also recognize and avoid ``immune'' targets that already contain a copy of Tn7. TnsD and TnsE are required to activate TnsABC as well as ...

Diameter of Cayley graphs generated by transposition trees  

CERN Document Server

A problem of much theoretical and practical interest is to determine or estimate the diameter of various families of Cayley graphs. Let $\\Gamma$ be a Cayley graph on $n!$ vertices generated by a transposition tree on vertex set ${1,2,...,n}$. In an oft-cited paper \\cite{Akers:Krishnamurthy:1989} (cf. also \\cite[p. 188]{Hahn:Sabidussi:1997}), it is shown that the diameter of $\\Gamma$ is bounded as $$\\diam(\\Gamma) \\le \\max_{\\pi \\in S_n}{c(\\pi)-n+\\sum_{i=1}^n \\dist_T(i,\\pi(i))},$$ where the maximum is over all permutations in $S_n$, $c(\\pi)$ denotes the number of cycles in the disjoint cycle representation of $\\pi$, and $\\dist_T$ is the distance function on pairs of vertices of the tree. Observe that evaluating this upper bound requires $\\Omega(n! n^2)$ computations since the quantity in braces above needs to be evaluated for each permutation in $S_n$. In this work, we describe an algorithm to estimate the diameter of the Cayley graph which requires far fewer computations, and furthermore, we show that the value...

Surgical transposition of the ovaries: Imaging findings in 14 patients  

International Nuclear Information System (INIS)

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

Transposition of the EU cogeneration directive: A vision for Portugal  

International Nuclear Information System (INIS)

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. (author)

Congenitally corrected transposition in the adult: detection by radionuclide angiocardiography  

International Nuclear Information System (INIS)

Congenitally corrected transposition (CCT) of the great vessels is an uncommon anomaly usually detected in children because of associated severe cardiac malformations. When these are absent, patients may be hemodynamically normal, but associated cardiac abnormalities are usually present in CCT, leading to symptoms in adulthood. When CCT is suggested in an adult, diagnosis by means of ultrasound may be difficult. Radionuclide angiocardiography (RA) is a simple, noninvasive method by which to diagnose CCT. The authors found consistent morphologic scintigraphic results in 13 patients with proved CCT, leading to establishment of reliable diagnostic criteria. In all instances of situs solitus the aorta ascends and descends on the left with vertical orientation. In the case of situs inversus, the aorta ascends and descends on the right with vertical orientation. The authors criteria are independent of the situs and cardiac position, unlike earlier reports by others. They believe images obtained in the anterior projection are sufficient for the study. The practical application of RA study in patient diagnosis is demonstrated, giving special attention to patients referred because of situs solitus and dextrocardia, in which CCT is known to be present in 50% of cases

Sweet basil, a plant that is extensively cultivated in some countries, is used to enhance the flavour of salads, sauces, pasta and confectioneries as both a fresh and dried herb. To determine the effect of drying methods on qualitative and quantitative characteristics of the plant and essential oil of basil, two landraces, Purple and Green, were dried in sunlight, shade, mechanical ovens at 40 °C and 60 °C, a microwave oven at 500 W and by freeze-drying. For comparison, the essential oils of all samples were extracted by hydrodistillation and analyzed using GC and GC-MS. The highest essential oil yields (v/w on dry weight basis) were obtained from shade-dried tissue in both landraces followed by the freeze-dried sample of the purple landrace and the fresh sample of green landrace. Increasing the drying temperature significantly decreased the essential oil content of all samples. Significant changes in the chemical profile of the essential oils from each of the landrace were associated with the drying method, including the loss of most monoterpene hydrocarbons, as compared with fresh samples. No significant differences occurred among several constituents in the extracted essential oils, including methyl chavicol (estragole), the major compound in the oil of both landraces, whether the plants were dried in the shade or sun, oven at 40 °C or freeze-dried, as compared with a fresh sample. The percentage methyl chavicol in the oil, however, decreased significantly when the plant material was dried in the oven at 60 °C or microwaved. In addition, linalool, the second major compound in the purple landrace, and geranial and neral, major compounds in the green landrace, decreased significantly when the plant tissue was dried in the oven at 60 °C or microwaved.

CT findings of portal vein aneurysm  

Energy Technology Data Exchange (ETDEWEB)

To describe the CT findings of portal vein aneurysm in eight patients. All patients included in this study (two men and six women) underwent CT examinations between October 1996 and June1998. Of these eight, three were suffering from hepatic disease and portal hypertension. We determined the location, shape, size, and characteristics of the lesions, and the presence or absence of portal vein anomaly. Seven patients had intrahepatic portal vein aneurysm (at the umbilical portion of the left portal vein in five patients, between the transverse and umbilical portion of the left portal vein in one, and at the bifurcation of the anterior and posterior branch of the right portal vein in one), while extrahepatic portal vein aneurysm, at the confluence of the superior mesenteric and splenic vein was found in only one. Lesions were cyst-shaped in seven cases and saccular in one, and showed well-circumscribed, markedly enhanced mass, which communicated with the portal vein and/or gives off major branches. Portal vein anomaly, in which the right anterior segmental portal vein originated from the umbilical portion of the left portal vein, was seen in three patients. In all three, intrahepatic portal vein aneurysm was present at the umbilical portion of the left portal vein, and in one, the umbilical protion of the left portal vein was located to the right of the Cantlic line. CT examination can help reveal portal vein aneurysm by detecting a well-circumscribed, markedly enhanced mass which communicates with the portal vein and/or gives off major branches.

Congestive index of portal vein  

International Nuclear Information System (INIS)

In patients with portal hypertension, the blood flow volume is maintained despite decreased blood flow velocity due to enlargement of the vascular cross sectional area. Thus, the 'congestion index' of the portal vein, which is the ratio between the cross sectional area (cm2) and the blood flow velocity (cm/sec) determined by a Doppler ultrasonography, may be a sensitive index by which to assess portal hypertension. We performed Doppler ultrasonography on 24 normal subjects, 14 patients with biopsy proved chronic active hepatitis and 55 patients with liver cirrhosis in order to assess the diagnostic value of the congestion index. The cross sectional area of the portal vein was significantly enlarged and the mean blood flow velocity was significantly reduced in patients with liver cirrhosis compared with controls. However, the blood flow volume was no difference. The congestion index of the portal vein was significantly increased in patients with liver cirrhosis (0.113+0.035) compared with patients with chronic active hepatitis(0.078+0.029) (p<0.001) and controls (0.053+0.016) (p<0.001). The sensitivity, specificity and predictability of the congestion index for detection of patients with the cirrhosis of the liver were 76.4%, 100% and 100% respectively, when the normal range was set at mean+2SD. The results suggest that the congestion index of the portal vein may pla a significant role in diagnosis of portal hypertensive patientsts

The "sliding door" technique for closure of abdominal wall defects after rectus abdominis musculocutaneous flap transposition.  

Science.gov (United States)

Radical surgery is often necessary in patients with local recurrence of rectal cancer or in those with carcinoma associated with an anal fistula. The surgery may include extended excision of the perineal area and can create a large dead space in the pelvis and a large skin defect, often necessitating reconstruction of the pelvic floor using rectus abdominis musculocutaneous (RAM) flap transposition. Wound dehiscence and incisional hernia are common complications of RAM flap transposition. We report herein our encounter with 3 patients in whom we used a "sliding door" technique for reconstruction of the abdominal wall after the creation of a RAM flap. One patient underwent abdominoperineal resection with sacrectomy and RAM flap transposition; he experienced a postoperative surgical site infection and wound dehiscence, which we urgently repaired by reconstructing the abdominal wall using the sliding door technique. Two other patients underwent posterior pelvic exenteration with sacrectomy and RAM flap transposition. These patients underwent simultaneous abdominal wall reconstruction using the sliding door technique. No patient experienced postoperative pelvic sepsis, wound dehiscence, or incisional hernia. The sliding door technique might be useful for preventing wound dehiscence and incisional hernia in patients undergoing RAM flap transposition. PMID:24394135

Laparoscopic ovarian transposition before pelvic radiation in rectal cancer patient: safety and feasibility  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Infertility due to pelvic radiation for advanced rectal cancer treatment is a major concern particularly in young patients. Pre-radiation laparoscopic ovarian transposition may offer preservation of ovarian function during the treatment however its use is limited. Aim The study investigates the safety, feasibility and effectiveness of pre-radiation laparoscopic ovarian transposition and its effect on ovarian function in the treatment o locally advanced rectal cancer. Methods Charts review of all young female patients diagnosed with locally advanced rectal cancer, underwent laparoscopic ovarian transposition, then received preoperative radiotherapy at king Faisal Specialist Hospital and Research Centre between 2003–2007. Results During the period studied three single patients age between 21–27?years underwent pre-radiation laparoscopic ovarian transposition for advanced rectal cancer. All required pretreatment laparoscopic diversion stoma due to rectal stricture secondary to tumor that was performed at the same time. One patient died of metastatic disease during treatment. The ovarian hormonal levels (FSH and LH were normal in two patients. One has had normal menstrual period and other had amenorrhoea after 4?months follow-up however her ovarian hormonal level were within normal limits. Conclusions Laparoscopic ovarian transposition before pelvic radiation in advanced rectal cancer treatment is an effective and feasible way of preservation of ovarian function in young patients at risk of radiotherapy induced ovarian failure. However, this procedure is still under used and it is advisable to discuss and propose it to suitable patients.

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

International Nuclear Information System (INIS)

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

Coronary artery anatomy in complete transposition with situs solitus and dextrocardia.  

Science.gov (United States)

The coronary artery anatomy of complete transposition with situs solitus/levocardia (CTSSL) has been well elucidated in the current era of arterial switch operation. However, coronary artery for complete transposition with situs solitus/dextrocardia (CTSSD) has never been documented. Coronary anatomy of transposition and aortopulmonary rotation were identified by angiography or surgical intervention from 1988 to 2007 at our hospital. The degree of aortopulmonary rotation was defined by the aortic sinus pattern on lateral angiogram. Apicocaval ipsilaterality was defined as situs solitus/dextrocardia or situs inversus/levocardia. The coronary artery anatomy in 3 cases of CTSSD was analyzed and correlated with those patients having transposition with the same coronary pattern but without apicocaval ipsilaterality, i.e., 276 cases with CTSSL and 8 cases with complete transposition with situs inversus/dextrocardia (CTSID). Fisher's exact test was used to determine statistical significance. All three cases with CTSSD (with apicocaval ipsilaterality) had a single coronary artery piercing into the left-hand sinus with a right coronary artery in the posterior atrioventricular groove, whereas all 284 cases without apicocaval ipsilaterality (CTSSL or CTSID) had the left circumflex artery in the posterior atrioventricular groove. The aorta was significantly less left laterally rotated in CTSSD than the other 2 cases of CTSSL and 3 cases of CTSSD with a similar coronary pattern (p < 0.05). One may anticipate coronary artery anatomy in the posterior atrioventricular groove based on apicocaval ipsilaterality, which in turn decreases aortopulmonary rotation to predict the central coronary pattern.

Individual draining vein of intralobar pulmonary sequestration  

International Nuclear Information System (INIS)

We analyzed the routes of draining veins in 7 cases of intralobar pulmonary sequestration (ILS) and 6 cases of bronchial atresia (BA) by multidetector CT and on 3D reconstructed images. In 2 cases of ILS with systemic venous drainage and 4 of 5 cases with pulmonary venous drainage, the primary veins penetrated the abnormal lungs. In another case, the main vein bypassed the border of the lung, but a small number of branches joined from the normal lung. In all cases of BA, draining veins distributed outside the abnormal lung. The finding that ILS has its own draining veins supports the theory of its congenital origin from an accessory lung bud. (author)

Dental transposition of canine and lateral incisor and impacted central incisor treatment: A case report  

Science.gov (United States)

Introduction Dental transposition and impaction are disorders related to ectopic eruption or failure in tooth eruption, which can affect child physical, mental and social development and may be difficult to be clinically solved. Methods We describe a case of transposition between the upper left canine and lateral incisor associated with impaction of the central incisor on the same side, in a 12-year-old patient. Conservative treatment involving surgical-orthodontic correction of transposed teeth and traction of the central incisor was conducted. Conclusion The option of correcting transposition and orthodontic traction by means of the segmented arch technique with devices such as cantilever and TMA rectangular wire loops, although a complex alternative, was proved to be esthetically and functionally effective.

Interdisciplinary approach for bilateral maxillary canine: First premolar transposition with complex problems in an adult patient.  

Science.gov (United States)

Adult patients seeking orthodontic care were increased nowadays not only on esthetic need but also on functional demand. But problems with adult patients were not only malocclusions but also dental caries, pulpal pathology, missing teeth, muco-gingival problems and loss of supporting structures. We report here a case of 35-year-old female with complete transposition referred as a positional interchange of two permanent teeth within the same quadrant of the dental arch along with gingival recession of the lower anteriors and missing molars. Gingival health was improved by free gingival graft in lower anteriors followed by fixed orthodontic procedure to correct transposition. Based on transposition crown recontouring and restoration was done along with replacement of missing molars with fixed prosthesis. Thus, proper treatment planning with interdisciplinary management improves not only the esthetics and occlusal relationship but also with stable results. PMID:23956606

Radiological evaluation of congenital pulmonary vein obstruction  

International Nuclear Information System (INIS)

Congenital obstruction of pulmonary vein is presented as chronic cough, hemoptysis, and recurrent pneumonias, which are caused by long-standing pulmonary congestion. Congenital obstruction of pulmonary vein without anomalous drainage can cause long-standing pulmonary congestion and pulmonary arterial hypertension, and it may include stenosis of individual pulmonary veins or total pulmonary vein atresia. We reviewed seven cases of pulmonary vein obstruction, five of which accompanied other cardiac anomalies. Right pulmonary veins were involved in all seven cases including one bilateral case. Pulmonary veins were occluded totally in five and partially in three lungs. Pulmonary catheterization and angiography were done for diagnosis. Chest radiographs of total occlusion cases showed decreased lung volume, features of pulmonary edema, interstitial lesions, and pleural thickening, which were quite specific, whereas pulmonary venous dilatation was dominant findings in partial obstruction cases. Pulmonary perfusion scans (n=3) showed total perfusion defects in the cases of total occlusion of veins. MR imaging (n=2) demonstrated total occlusion of pulmonary veins in the veno atrial junction in two, and membranous focal obstruction in one lung. Two patients had pneumonectomy and histological confirmation. Although catheterization and angiography are essential for the diagnosis, MR imaging is thought to be useful for the diagnosis of pulmonary vein obstructionlmonary vein obstruction

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

Science.gov (United States)

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.

Compression syndrome of the left renal vein  

Energy Technology Data Exchange (ETDEWEB)

Severe compression of the left renal vein produces a pressure gradient between it and the inferior vena cava and results in changes in haemodynamics. The cause of the narrowing is usually the aorta, less commonly the superior mesenteric artery. Compression of the left renal vein may be responsible for a number of abnormalities such as primary varicoceles, primary varices of the ovarian, renal, pelvic and ureteric veins on the left, the more frequent occurrence of unilateral renal vein thrombosis on the left and the development of renovascular hypertension. One hundred and twenty-three selective phlebograms of the left renal vein and CT examinations of this structure in a further 87 patients acting as a control group were carried out. The significance of compression of the left renal vein as an aetiological factor in the development of the above mentioned abnormalities is discussed.

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 bank of Gabor filters. Then Fisher Discriminated Analysis (FDA is used to reduce the dimension of the features vectors. For vein pattern verification, this work uses Nearest Neighbors method. The EER of the proposed method is 0.2335%.

Comparison of the Complications of Central Vein Catheters and Arterio-Venous Fistulae in Children on Chronic Hemodialysis  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Complications related to vascular access are among the most important causes of morbidity in children chronically on hemodialysis. This study was designed to determine the prevalence of the central vein catheters (CVC and arterio-venous fistulae (AVF in children on chronic hemodialysis. Methods: This study includes 68 children who have been treated with hemodialysis in Dr. Sheikh Hospital, Mashhad, Iran, during 2000-2005. Physical examination, clinical and paraclinical findings were recorded in special charts. Findings: Out of 68 patients treated with hemodialysis 29 (42.6% were female and 39 (57.3% male. The average duration time of hemodialysis was 15.8 months. Before performing AVF, the central venous catheters were placed in subclavian vein in 28 patients (41.1% and internal jugular vein in 26 patients (38.2%. The fistula placed was radio-cephalic in 29 (42.6% and brachio-basilic in 33 children (48.5%. 48 patients (77.4% underwent only one surgery for AVF. The most frequent complications of central venous catheters were: catheter infection (48.1%, inadvertent extraction of the catheters (7.4%, cardiac arrhythmia (1.8% and hemothorax (1.8%. The most common complications of AVF in decreasing order of frequency were: non-functional fistula due to thrombosis or hematoma (20.9%, infection (12.9%, aneurysms (11.2% and ischemia of the hand presenting as paresthesia, dysesthesia and pain (11.2%. Overall, 10 (18.5% patients were hospitalized due to the complications of CVC and 20 (29.4% for the complications of AVF. Conclusion: The most frequently observed complications of CVC and AVF were catheter infection and non-functional fistula. The risk factors for AVF dysfunction were young age, hypotension and hemodialysis without administration of heparin.

On dynamics of uranium vein mineralization  

International Nuclear Information System (INIS)

The formation of urnaium vein deposits and the essence of consanguinity of the mineralization and wall metasomatites are considered. The formation of uranium mineralization is analysed from the positions of Korzhinsky D. S. : the formation of metasomatite aureole and associated vein ores take place as a result of the development of one solution flow while the formation of mineral vein associations occurs on the background of contineous filtration of the solution during metasomato is due to a repeated (pulse) half-opening of fractures and their filling with a part of filtrating solution. The analysis of the available information on the example of two different uranium manifestations permits to reveal certain relations both in the character of wall rock alterations and between the metasomatosis and the formation of ore minerals in veins. The conclusion is made that spatial-time correlations of vein formations with wall metasomatites attest that the pulse formation of ores in veinlets occurs on the background and in interrelation with a consecutive precipitation of components in the aureole volume. The analysis of element migration dynamics in wall aureole carried out from the positions of the Korzhinsky hypothesis of the advance wave of acid components that takes into account the interaction of continuous and pulse mechanisms of solution movement permits to avoid contradictions when interpreting the processes of wall rock alterations and vein ore-forming, and permits totions and vein ore-forming, and permits to make a common scheme of vein ore-genesis

Guide Wire Migration During Femoral Vein Catheterization  

Directory of Open Access Journals (Sweden)

Full Text Available 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.

Dedifferentiation-mediated changes in transposition behavior make the Activator transposon an ideal tool for functional genomics in rice  

Digital Repository Infrastructure Vision for European Research (DRIVER)

There is an inverse relationship between the level of cytosine methylation in genomic DNA and the activity of plant transposable elements. Increased transpositional activity is seen during early plant development when genomic methylation patterns are first erased and then reset. Prolonging the period of hypomethylation might therefore result in an increased transposition frequency, which would be useful for rapid genome saturation in transposon-tagged plant lines. We tested this hypothesis us...

Transposition of the great arteries and cor triatriatum: a rare combination.  

Science.gov (United States)

In this case report, we present a 5-month-old girl diagnosed with a unique combination of transposition of the great arteries and cor triatriatum sinistra. A 1-day-old female patient presented to our hospital with cyanosis since the early neonatal period. We confirmed transposition of the great arteries by echocardiography. The patient underwent arterial switch operation on day 8 and was discharged on day 35. After 5 months of the operation, the patient had a lower respiratory tract infection and was unable to gain weight. Echocardiography revealed mild neopulmonary regurgitation, minimal neoaortic regurgitation, and pulmonary arterial hypertension. In addition, a fibrous membrane was also seen dividing the left atrium. The patient was diagnosed with cor triatriatum and underwent successful resection of the membrane. PMID:24018011

Pig transgenesis by piggyBac transposition in combination with somatic cell nuclear transfer.  

Science.gov (United States)

The production of animals by somatic cell nuclear transfer (SCNT) is inefficient, with approximately 2% of micromanipulated oocytes going to term and resulting in live births. However, it is the most commonly used method for the generation of cloned transgenic livestock as it facilitates the attainment of transgenic animals once the nuclear donor cells are stably transfected and more importantly as alternatives methods of transgenesis in farm animals have proven even less efficient. Here we describe piggyBac-mediated transposition of a transgene into porcine primary cells and use of these genetically modified cells as nuclear donors for the generation of transgenic pigs by SCNT. Gene transfer by piggyBac transposition serves to provide an alternative approach for the transfection of nuclear donor cells used in SCNT. PMID:23857557

Formulation and in Vivo Evaluation for Anti-Aging Effects of an Emulsion Containing Basil Extract Using non- Invasive Biophysical Techniques  

Directory of Open Access Journals (Sweden)

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.

Endovenous ablation of the saphenous vein.  

Science.gov (United States)

The introduction of the minimally invasive, endovenous thermal techniques of superficial reflux ablation have revolutionized the treatment of varicose veins in the last 8 years. The ease of performance even in an office setting, reduced discomfort, and quicker return to normal activity have resulted in universally superior patient acceptance and have made these endovenous procedures the mainstay of present treatment of varicose veins. With encouraging early and mid-term results, future developments in this field must mandate standardization of technical aspects, follow-up imaging, and reporting. The significance of reflux in the great saphenous vein stump, of reflux-free recanalization of a segment of the vein, and their potential for causing recurrent varicose veins remains unknown. The incidence of groin neovascularization and its significance needs to be determined. Ultrasound-guided foam sclerotherapy is also emerging as a competitor to other endovenous techniques and is particularly useful in superficial and tortuous veins not ideally suited for endovenous thermal ablation, as well as recanalized segments of ablated veins.

Portal vein gas in emergency surgery  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Portal vein gas is an ominous radiological sign, which indicates a serious gastrointestinal problem in the majority of patients. Many causes have been identified and the most important was bowel ischemia and mesenteric vascular accident. The presentation of patients is varied and the diagnosis of the underlying problem depends mainly on the radiological findings and clinical signs. The aim of this article is to show the clinical importance of portal vein gas and its management in emergency surgery. Methods A computerised search was made of the Medline for publications discussing portal vein gas through March 2008. Sixty articles were identified and selected for this review because of their relevance. These articles cover a period from 1975–2008. Results Two hundreds and seventy-five patients with gas in the portal venous system were reported. The commonest cause for portal vein gas was bowel ischemia and mesenteric vascular pathology (61.44%. This was followed by inflammation of the gastrointestinal tract (16.26%, obstruction and dilatation (9.03%, sepsis (6.6%, iatrogenic injury and trauma (3.01% and cancer (1.8%. Idiopathic portal vein gas was also reported (1.8%. Conclusion Portal vein gas is a diagnostic sign, which indicates a serious intra-abdominal pathology requiring emergency surgery in the majority of patients. Portal vein gas due to simple and benign cause can be treated conservatively. Correlation between clinical and diagnostic findings is important to set the management plan.

Correction of incomplete penoscrotal transposition by a modified Glenn-Anderson technique  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose: Penoscrotal transposition may be partial or complete, resulting in variable degrees of positional exchanges between the penis and the scrotum. Repairs of penoscrotal transposition rely on the creation of rotational flaps to mobilise the scrotum downwards or transpose the penis to a neo hole created in the skin of the mons-pubis. All known techniques result in complete circular incision around the root of the penis, resulting in severe and massive oedema of the penile skin, which delays correction of the associated hypospadias and increases the incidence of complications, as the skin vascularity and lymphatics are impaired by the designed incision. A new design to prevent this post-operative oedema, allowing early correction of the associated hypospadias and lowering the incidence of possible complications, had been used, whose results were compared with other methods of correction. Materials and Methods: Ten patients with incomplete penoscrotal transposition had been corrected by designing rotational flaps that push the scrotum back while the penile skin remains attached by small strip to the skin of the mons-pubis. Results : All patients showed an excellent cosmetic outcome. There was minimal post-operative oedema and no vascular compromise to the penile or scrotal skin. Correction of associated hypospadias can be performed in the same sitting or in another sitting, without or with minimal complications. Conclusion: This modification, which maintains the penile skin connected to the skin of the lower abdomen by a small strip of skin during correction of penoscrotal transposition, prevents post-operative oedema and improves healing with excellent cosmetic appearance, allows one-stage repair with minimal complications and reduce post-operative complications such as urinary fistula and flap necrosis.

Transposable elements have influenced the genetic and physical composition of all modern organisms. Defining how different transposons select target sites is critical for understanding the biochemical mechanism of this type of recombination and the impact of mobile genes on chromosome structure and function. Phage Mu replicates in Gram-negative bacteria using an extremely efficient transposition reaction. Replicated copies are excised from the chromosome and packaged into virus particles. Eac...

DNA transposition by protein transduction of the piggyBac transposase from lentiviral Gag precursors  

Digital Repository Infrastructure Vision for European Research (DRIVER)

DNA transposon-based vectors have emerged as gene vehicles with a wide biomedical and therapeutic potential. So far, genomic insertion of such vectors has relied on the co-delivery of genetic material encoding the gene-inserting transposase protein, raising concerns related to persistent expression, insertional mutagenesis and cytotoxicity. This report describes potent DNA transposition achieved by direct delivery of transposase protein. By adapting integrase-deficient lentiviral particles (L...

ISEcp1-Mediated Transposition of qnrB-Like Gene in Escherichia coli?  

Digital Repository Infrastructure Vision for European Research (DRIVER)

A novel QnrB-like plasmid-mediated resistance determinant, QnrB19, was identified from an Escherichia coli clinical isolate from Colombia. Its gene was associated with an ISEcp1-like insertion element that did not act as a promoter for its expression. Using an in vitro model of transposition, we showed that the ISEcp1-like element was able to mobilize the qnrB19 gene.

Characterization of Lactococcus lactis UV-sensitive mutants obtained by ISS1 transposition.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Studies of cellular responses to DNA-damaging agents, mostly in Escherichia coli, have revealed numerous genes and pathways involved in DNA repair. However, other species, particularly those which exist under different environmental conditions than does E. coli, may have rather different responses. Here, we identify and characterize genes involved in DNA repair in a gram-positive plant and dairy bacterium, Lactococcus lactis. Lactococcal strain MG1363 was mutagenized with transposition vector...

Letter-transposition effects are not universal: The impact of transposing letters in Hebrew  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We examined the effects of letter transposition in Hebrew in three masked-priming experiments. Hebrew, like English has an alphabetic orthography where sequential and contiguous letter strings represent phonemes. However, being a Semitic language it has a non-concatenated morphology that is based on root derivations. Experiment 1 showed that transposed-letter (TL) root primes inhibited responses to targets derived from the non-transposed root letters, and that this inhibition was unrelated to...

On tests of entanglement: States of rank 2, partial transposition and generalized concurrences  

CERN Document Server

We consider the positive partial transposition test (PPT) and the generalized concurrence test for the entanglement of bipartite quantum systems in the simplest case not previously studied in the literature. This is the case of 2 X 4 states of rank 2. We prove that the PPT test gives a necessary and sufficient condition of separability and identify a set of entangled states not detected using generalized concurrences.

Despite balloon atrial septostomy within the first days of life, some patients with complete transposition of the great arteries die before reaching elective definitive surgery in the second six months of life. To discover why, we analysed the fate of 144 patients who had balloon atrial septostomy after 1966, using a modified logrank survival test with multivariate capability. Patients were withdrawn "alive" on reaching definitive surgery. The following largely independent factors were associ...

Transposon systems are widely used for generating mutations in various model organisms. PiggyBac (PB) has recently been shown to transpose efficiently in the mouse germ line and other mammalian cell lines. To facilitate PB's application in mammalian genetics, we characterized the properties of the PB transposon in mouse embryonic stem (ES) cells. We first measured the transposition efficiencies of PB transposon in mouse embryonic stem cells. We next constructed a PB/SB hybrid transposon to co...

Two-stage posterior cross-labial transposition flap: a novel technique for labium minus reconstruction.  

Science.gov (United States)

Distinctive asymmetry of the labia minora is an underestimated complication that can be congenital, post-traumatic, or occur after oncological intervention or aesthetic labioplasty. Affected women can be restricted functionally and in their sense of self-worth, aesthetic appearance and sexual life. In presenting this case of post-oncological labia minora asymmetry, we demonstrate our method of the two-stage posterior cross-labial transposition flap as a reliable technique for unilateral labium minus reconstruction.

Valsalva and gravitational variability of the internal jugular vein and common femoral vein: Ultrasound assessment  

International Nuclear Information System (INIS)

Purpose: Central venous cannulation via the common femoral vein is an important starting point for many interventions. The purpose of this study was to determine the optimum conditions for cannulation of the femoral vein and to compare these with the relative changes in the internal jugular vein. Methods: High-resolution 2D ultrasound was utilised to determine variability of the calibre of the femoral and internal jugular veins in 10 healthy subjects. Venous diameter was assessed during the Valsalva manoeuvre and in different degrees of the Trendelenburg position. Results: The Valsalva manoeuvre significantly increased the size of the femoral and internal jugular veins. There was a relatively greater increase in femoral vein diameter when compared with the internal jugular vein of 40 and 29%, respectively. Changes in body inclination (Trendelenburg position) did not significantly alter the luminal diameter of the femoral vein. However, it significantly increased internal jugular vein diameter. Conclusions: Femoral vein cannulation is augmented by the Valsalva manoeuvre but not significantly altered by the gravitational position of the subject

A reappraisal of saphenous vein grafting  

Directory of Open Access Journals (Sweden)

Full Text Available Autologous saphenous vein grafting has been broadly used as a bypass conduit, interposition graft, and patch graft in a variety of operations in cardiac, thoracic, neurovascular, general vascular, vascular access, and urology surgeries, since they are superior to prosthetic veins. Modified saphenous vein grafts (SVG, including spiral and cylindrical grafts, and vein cuffs or patches, are employed in vascular revascularization to satisfy the large size of the receipt vessels or to obtain a better patency. A loop SVG helps flap survival in a muscle flap transfer in plastic and reconstructive surgery. For dialysis or transfusion purposes, a straight or loop arteriovenous fistula created in the forearm or the thigh with an SVG has acceptable patency. The saphenous vein has even been used as a stent cover to minimize the potential complications of standard angioplasty technique. However, the use of saphenous vein grafting is now largely diminished in treating cerebrovascular disorders, superior vena cava syndrome, and visceral revascularization due to the introduction of angioplasty and stenting techniques. The SVG remains the preferable biomaterial in coronary artery bypass, coronary ostioplasty, free flap transfer, and surgical treatment of Peyronie disease. Implications associated with saphenous vein grafting in vascular access surgery for the purpose of dialysis and chemotherapy are considerable. Vascular cuffs and patches have been developed as an important and effective means of enhancing the patency rates of the grafts by linking the synthetic material to the receipt vessel. In addition, saphenous veins can be a cell source for tissue engineering. We review the versatile roles that saphenous vein grafting has played as well as its current status in therapy.

DNA transposition by protein transduction of the piggyBac transposase from lentiviral Gag precursors  

DEFF Research Database (Denmark)

DNA transposon-based vectors have emerged as gene vehicles with a wide biomedical and therapeutic potential. So far, genomic insertion of such vectors has relied on the co-delivery of genetic material encoding the gene-inserting transposase protein, raising concerns related to persistent expression, insertional mutagenesis and cytotoxicity. This report describes potent DNA transposition achieved by direct delivery of transposase protein. By adapting integrase-deficient lentiviral particles (LPs) as carriers of the hyperactive piggyBac transposase protein (hyPBase), we demonstrate rates of DNA transposition that are comparable with the efficiency of a conventional plasmid-based strategy. Embedded in the Gag polypeptide, hyPBase is robustly incorporated into LPs and liberated from the viral proteins by the viral protease during particle maturation. We demonstrate lentiviral co-delivery of the transposase protein and vector RNA carrying the transposon sequence, allowing robust DNA transposition in a variety of cell types. Importantly, this novel delivery method facilitates a balanced cellular uptake of hyPBase, as shown by confocal microscopy, and allows high-efficiency production of clones harboring a single transposon insertion. Our findings establish engineered LPs as a new tool for transposase delivery. We believe that protein transduction methods will increase applicability and safety of DNA transposon-based vector technologies.

A fast algorithm for the multiple genome rearrangement problem with weighted reversals and transpositions  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Due to recent progress in genome sequencing, more and more data for phylogenetic reconstruction based on rearrangement distances between genomes become available. However, this phylogenetic reconstruction is a very challenging task. For the most simple distance measures (the breakpoint distance and the reversal distance, the problem is NP-hard even if one considers only three genomes. Results In this paper, we present a new heuristic algorithm that directly constructs a phylogenetic tree w.r.t. the weighted reversal and transposition distance. Experimental results on previously published datasets show that constructing phylogenetic trees in this way results in better trees than constructing the trees w.r.t. the reversal distance, and recalculating the weight of the trees with the weighted reversal and transposition distance. An implementation of the algorithm can be obtained from the authors. Conclusion The possibility of creating phylogenetic trees directly w.r.t. the weighted reversal and transposition distance results in biologically more realistic scenarios. Our algorithm can solve today's most challenging biological datasets in a reasonable amount of time.

Transposition of the Zorro2 retrotransposon is activated by miconazole in Candida albicans.  

Science.gov (United States)

Zorro2 is a member of a non-long terminal repeat (LTR) retrotransposon family in Candida albicans, but as yet no clear evidence has been provided to establish either transcription or transposition activity for Zorro2. In this study, the relative expression changes of two open reading frames in Zorro2, ORF19.7274 and ORF19.7275, were examined in response to miconazole (MCZ), and were found to be increased by this treatment. As well, the copy number and the transcripts of Zorro2 in MCZ-induced resistant daughter strains were increased compared to the parental strain, indicating that transposition of Zorro2 occurred during long-term MCZ treatment. Intriguingly, the transcription activity of Zorro2 retrotransposons was significantly inhibited when the cells were treated with MCZ together with antioxidant N-acetyl-L-cysteine (NAC). As both the level of intracellular reactive oxygen species (ROS) and the expression of genes involving DNA repair activated by MCZ were reduced when combined with the treatment of NAC, we propose that the damage caused by accumulation of ROS under MCZ stress is a major reason for the transcription and transposition activation of the Zorro2 retrotransposon.

How Is the Serial Order of a Spatial Sequence Represented? Insights From Transposition Latencies.  

Science.gov (United States)

How is the serial order of a spatial sequence represented in short-term memory (STM)? Previous research by Farrell and Lewandowsky (Farrell & Lewandowsky, 2004; Lewandowsky & Farrell, 2008) has shown that 5 alternative mechanisms for the representation of serial order can be distinguished on the basis of their predictions concerning the response times accompanying transposition errors. We report 3 experiments involving the output-timed serial recall of sequences of seen spatial locations that tested these predictions. The results of all 3 experiments revealed that transposition latencies are a negative function of transposition displacement, but with a reduction in the slope of the function for postponement, compared with anticipation errors. This empirical pattern is consistent with that observed in serial recall of verbal sequences reported by Farrell and Lewandowsky (2004), and with the predictions of a competitive queuing mechanism, within which serial order is represented via a primacy gradient of activations over items combined with associations between items and positional markers, and with suppression of items following recall. The results provide the first clear evidence that spatial and verbal STM rely on some common mechanisms and principles for the representation of serial order.

Abernethy malformation with portal vein aneurysm.  

Science.gov (United States)

We present the case of a 24-year-old man who was incidentally diagnosed with congenital extrahepatic portosystemic shunt with portal vein aneurysm during an investigation for non-specific abdominal pain. These are rare anomalies, and to the best of our knowledge, this is the first case reported with both anomalies associated together. Ultrasound, including color Doppler, computed tomography, and magnetic resonance imaging were performed which revealed a side-to-side shunt between the extrahepatic portal vein and the inferior vena cava, with aneurysmal fusiform dilatation of the proximal intrahepatic portal vein which ended abruptly. Etiology, clinical significance, and management strategies with regard to these abnormalities are discussed. PMID:18814137

Plantar vein thrombosis is an unusual and under-diagnosed condition that affects the plantar deep venous system. Current ultrasound investigation protocols for deep venous thrombosis neglect this entity. To our knowledge, there are only seven reports in the literature of 20 patients with plantar vein thrombosis detected with sonography without an associated pulmonary embolism. We present a case report of a patient with a plantar vein thrombosis associated with pulmonary embolism. Patients who present with pain and/or swelling of the foot should undergo ultrasound examination and careful evaluation for respiratory symptoms. PMID:24429378

Portal Vein Thrombosis after Splenectomy  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Aim of the work: Splenectomy is a common operation but it carries the danger of many postoperative complications. One of the most important complications is the portal vein thrombosis (PVT, which may be fatal due to development of bowel ischemia and severe portal hypertension. Due to the effect of hypobaric hypoxia and higher liability for thrombosis encountered in high altitude areas, PVT may represent an actual problem in Taif province. The aim of this retrospective study is to detect the incidence, pattern of presentation, laboratory, radiological and results of treatment of cases of PVT following splenectomy.Methods: In this study, we reviewed all cases of splenectomy performed in King Abdul Aziz Specialist Hospital, Taif, Saudi Arabia from January 2007 to January 2012. Cases of PVT following splenectomy were analyzed for incidence, pattern of presentation, laboratory, radiological and results of treatment. Results: This study involved 50 patients (40 males and 10 females admitted in the surgical department of King Abdul Aziz Specialist Hospital, Taif, Saudi Arabia from January 2007 to January 2012. Eight cases of Portal vein thrombosis (16% out of 50 splenectomies were identified. These 8 patients included: 4/10 of the patients (40% suffering from myeloproliferative (MP, 3 of them (75% had spleen weight greater than 3,000 g, 3/12 (25% of the hemolytic anemia patients, and 1/10 of the patients (10% operated upon for Hypersplenism. All patients had splenomegaly with mean weight of 1540 Gms (range 460 to 3850 g. Presenting symptoms included; anorexia in 7/8 cases (87.5%, abdominal pain in 6 (75%, and in all cases there was elevation in D-Dimer level, leukocyte and platelet counts. All diagnoses were made by contrast-enhanced computed tomography scan, and anticoagulation was initiated immediately. One/8 patients (12.5% died from progressive liver cell failure; the others are alive with no clinical sequalae at a mean follow up of 27 months.CONCLUSIONS: PVT is a relatively common complication of splenectomy in patients with Splenomegaly, especially in Taif and related districts in which there is already a higher incidence of thrombotic disorders. The surgeon has to be with high index of suspicion, for early diagnosis by contrast-enhanced computed tomography, and prompt anticoagulation for successful outcome.

Insecticidal activity of basil oil, trans-anethole, estragole, and linalool to adult fruit flies of Ceratitis capitata, Bactrocera dorsalis, and Bactrocera cucurbitae.  

Science.gov (United States)

Basil oil and its three major active constituents (trans-anethole, estragole, and linalool) obtained from basil (Oscimum basilicum L.) were tested on three tephritid fruit fly species [Ceratitis capitata (Wiedemann), Bactrocera dorsalis (Hendel), and Bactrocera cucurbitae (Coquillett)] for insecticidal activity. All test chemicals acted fast and showed a steep dose-response relationship. The lethal times for 90% mortality/knockdown (LT90) of the three fly species to 10% of the test chemicals were between 8 and 38 min. The toxic action of basil oil in C. capitata occurred significantly faster than in B. cucurbitae but slightly faster than in B. dorsalis. Estragole acted faster in B. dorsalis than in C. capitata and B. cucurbitae. Linalool action was faster in B. dorsalis and C. capitata than in B. cucurbitae. trans-Anethole action was similar to all three species. Methyl eugenol acted faster in C. capitata and B. cucurbitae than in B. dorsalis. When linalool was mixed with cuelure (attractant to B. cucurbitae male), its potency to the three fly species decreased as the concentration of cuelure increased. This was due to linalool hydrolysis catalyzed by acetic acid from cuelure degradation, which was confirmed by chemical analysis. When methyl eugenol (B. dorsalis male attractant) was mixed with basil oil, trans-anethole, estragole, or linalool, it did not affect the toxicity of basil oil and linalool to B. dorsalis, but it did significantly decrease the toxicity of trans-anethole and estragole. Structural similarity between methyl eugenol and trans-anethole and estragole suggests that methyl eugenol might act at a site similar to that of trans-anethole and estragole and serve as an antagonist if an action site exists. Methyl eugenol also may play a physiological role on the toxicity reduction. PMID:19253638

Detailed anatomy of the internal spermatic vein and the ovarian vein. Human cadaver study and operative spermatic venography: clinical aspects.  

Science.gov (United States)

The exact anatomical course of the spermatic vein and the ovarian vein (gonadal) has not been described in detail previously. To determine the precise anatomy of the gonadal veins an autopsy study of 70 fresh human cadavers (40 men, 10 women, 10 male stillborns and 10 female stillborns) was performed by making a resin cast of both gonadal veins which then was carefully dissected. The study showed absence of valves in the spermatic vein, cross-communications between the right and left spermatic veins, and communication between the spermatic and renal capsular veins, spermatic and ipsilateral ureteral veins, and spermatic ipsilateral colonic veins. For clarification of the presence of valves intraoperative antegrade spermatic venography was done in 6 men with and 5 without varicocele. In both groups valves were not detected. These observations regarding the anatomy of the spermatic vein and the ovarian vein may help to explain related clinical conditions. PMID:2005700

Perioperative management of a levoatrial cardinal vein in the absence of the brachiocephalic vein.  

Science.gov (United States)

Levoatrial cardinal vein is a rare congenital anomaly of the systemic veins. It is commonly associated with left-sided obstructive conditions such as aortic atresia, mitral atresia, and cor triatriatum. We report the case of a 14-year-old boy who was undergoing surgery for correction of a secundum atrial septal defect. Intraoperatively, we discovered that he had a levoatrial cardinal vein and no brachiocephalic vein. However, collateral vessels provided adequate flow to the right atrium, and the patient's left-sided venous pressure was not excessive, so we ligated the levoatrial cardinal vein and directly repaired the septal defect. Postoperatively, the left venous drainage was satisfactory and the patient was asymptomatic. In addition to our patient's case, we discuss the embryology, diagnosis, and treatment of levoatrial cardinal vein. PMID:23678224

Complications of umbilical vein catherisation. Case Report  

International Nuclear Information System (INIS)

Umbilical vein catheterization is a relatively easy procedure performed routinely on the neonate intensive care units. It provides a fast central vein access, but some complications have been described in the literature. Case Reports: We presented a case report of a premature infant (34 hbd) with extravasation of the parenteral nutrition and drugs to the liver after umbilical vein catheterization. Fever and increasing biochemical markers of infection were observed. USG revealed a heterogenic, well-limited space of 4 cm in diameter, located in the right lobe of the liver. CT excluded liver abscess. Considering neoplastic process or incorrect location of the catheter of the central vein, we performed liver biopsy. Results: Cytological and biochemical analysis of the aspirated fluid revealed extravasation of parenteral nutrition to the liver.Our case confirms the necessity of controlling a proper location of the central catheter right after its insertion and during hospitalization.

Ovarian vein thrombosis following total laparoscopic hysterectomy.  

Science.gov (United States)

Ovarian vein thrombosis usually occurs in pregnant patients, especially during the postpartum period. However, it is a rare complication following laparoscopic surgery in gynecology. The risk of a thromboembolic event is not well defined, and evidence-based guidelines regarding deep vein thrombosis prophylaxis in gynecological laparoscopic surgery are still lacking. Herein we report a rare case of ovarian vein thrombosis following total laparoscopic hysterectomy in a 35-year-old woman who developed a fever of unknown origin on postoperative day 3. A complete fever work-up was done. Her urine, vaginal stump and blood culture were all negative, and her white blood cell count was normal. CT revealed left ovarian vein thrombosis. The patient responded well to anticoagulation in conjunction with antibiotic therapy. PMID:23095296

Ovarian vein thrombosis in Behçet disease.  

Science.gov (United States)

We describe a 35-year-old Chinese woman with Behçet disease complicated by recurrent gastrointestinal flares. During admission for acute lower abdominal pain, a computed tomographic scan of the abdomen showed thrombosis of the left ovarian vein. She was treated with increased immunosuppressant and oral anticoagulant. Although she was not compliant to oral anticoagulant with her international normalized ratio frequently subtherapeutic, her symptoms abated and the thrombosis resolved. There has been only 1 reported case of a patient with Behçet disease presenting with postpartum ovarian vein thrombosis and pulmonary embolism and no reported case of Behçet disease with ovarian vein thrombosis occurring outside pregnancy and the puerperium. Ovarian vein thrombosis is a rare cause of abdominal pain that should be considered in patients with Behçet disease. PMID:22334267

Internal vein texture and vein evolution of the epithermal Shila-Paula district, southern Peru.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The epithermal Shila-Paula Au–Ag district is characterized by numerous veins hosted in Tertiary volcanic rocks of the Western Cordillera (southern Peru). Field studies of the ore bodies reveal a systematic association of a main E–W vein with secondary N55–60°W veins—two directions that are also reflected by the orientation of fluid-inclusion planes in quartz crystals of the host rock. In areas where this pattern is not recognized, such as the Apacheta sector, vein emplacement seems t...

[Thrombosis of the jugular vein during pregnancy].  

Science.gov (United States)

Thrombosis of the jugular vein is a rare complication during pregnancy. In most cases the thrombogenic factor was ovarian hyperstimulation syndrome occurred during the process of assisted reproductive technology or inherited or acquired thrombophilia. Authors report a case of jugular vein thrombosis occurred after in vitro fertilization. On the basis of the literature thromboprophylaxis should be indicated for patients who develop ovarian hyperstimulation syndrome, and also be considered for women with inherited or acquired thrombophilia, while undergoing assisted reproductive techniques.

The investigation of adrenal vein sampling technique  

International Nuclear Information System (INIS)

Objective: To investigate the technical points of adrenal vein sampling (AVS). Methods: AVS examinations were performed in 112 patients with suspicious primary aldosteronism. The angiographic manifestations of both adrenal veins were recorded. The clinical data and imaging findings were retrospectively analyzed. The success rate of superselective catheterization and the occurrence of complications were calculated. Results: The most common angiographic of left adrenal vein was gland-like type, while the right adrenal vein presented most commonly as triangular pattern. In patients who had the ratio of adrenal blood cortisol to peripheral blood cortisol ? 3, the superselective catheterization of left and right adrenal vein was succeeded in 106 cases (94.6%) and in 103 cases (92.0%), respectively, although no statistically significant difference existed between two groups (P=0.42). The occurrence of complications in left and right group was 2.7% (2/106) and 6.3% (7/103), respectively. Conclusion: Sufficient knowledge of the angiographic manifestations of adrenal veins is the essential prerequisite to a successful AVS performance. With higher success rate of catheterization and fewer complications, AVS is a reliable and effective examination method for the typing and side-localizing of primary aldosteronism. (authors)

Scattering Removal for Finger-Vein Image Restoration  

Directory of Open Access Journals (Sweden)

Full Text Available Finger-vein recognition has received increased attention recently. However, the finger-vein images are always captured in poor quality. This certainly makes finger-vein feature representation unreliable, and further impairs the accuracy of finger-vein recognition. In this paper, we first give an analysis of the intrinsic factors causing finger-vein image degradation, and then propose a simple but effective image restoration method based on scattering removal. To give a proper description of finger-vein image degradation, a biological optical model (BOM specific to finger-vein imaging is proposed according to the principle of light propagation in biological tissues. Based on BOM, the light scattering component is sensibly estimated and properly removed for finger-vein image restoration. Finally, experimental results demonstrate that the proposed method is powerful in enhancing the finger-vein image contrast and in improving the finger-vein image matching accuracy.

High Rosmarinic Acid Content in Induced Mutants and in in vitro Elicited Sweet Basil (Ocimum basilicum L. Callus  

Directory of Open Access Journals (Sweden)

Full Text Available Seeds of Sweet basil (Ocimum basilicum were exposed to different doses of gamma radiation and several mutants were selected upon morphological aberration. The spectrophotometric measurements showed that some mutants have 1.5 fold increase in the rosmarinic acid content comparing to the wild type. The in vitro shoot culture of mutants was established with fastest callus growth on MS media supplemented with 1 mg L-1 of 2,4-D and 0.25 mg L-1 of KIN. Addition of 5 g L-1 of yeast extract to the culture media led to increase the rosmarinic acid content with 3.4 fold further. The soluble and insoluble leaf protein fraction of mutants were screened on SDS PAGE. The protein patterns demonstrate that the soluble proteins have a more stable pattern than the insoluble proteins.

Role of Ovarian Transposition Based on the Dosimetric Effects of Craniospinal Irradiation on the Ovaries: A Case Report  

International Nuclear Information System (INIS)

In this study, we present a case of laparoscopic ovarian transposition to preserve ovarian function in an adult female patient treated with craniospinal irradiation for standard risk medulloblastoma. The prescribed dose to the craniospinal axis was 2340 cGy at 180 cGy per fraction and was delivered with 6-MV photons. Before ovarian transposition, magnetic resonance imaging (MRI) of the pelvis was obtained for localization of the ovaries and was registered with the planning computed tomography (CT) scan. Surgical clips allowed for CT localization of the ovaries after transposition. As a result of ovarian transposition, mean and maximum radiation doses decreased from 983 to 68 cGy and 1624 to 84 cGy for the left ovary and from 166 to 87 cGy and 723 to 103 cGy for the right ovary, respectively. Review of the literature indicates that such radiation doses are below the threshold that causes ovarian dysfunction and infertility. We conclude that ovarian localization with an MRI of the pelvis can be offered to females undergoing craniospinal irradiation. Transposition of the ovaries provides an option to preserve ovarian function in cases where the ovaries would otherwise be included within the radiation field

Penile vein ligation for venogenic impotence.  

Science.gov (United States)

We have performed penile vein ligation on 35 patients with venogenic impotence from July 1989 to December 1991. The criteria for surgery were (1) age less than 60 years; (2) negative vasoactive agent intracavernous injection but normal penile arterial function, and (3) abnormal venous leakage documented by dynamic infusion cavernosometry and cavernosography. The procedure in venous ligation is excision of the deep dorsal vein from coronary sulcus to pubic arch, and ligation of cavernous veins after identification. The average follow-up was 27.5 months (range 12-37 months) for 30 patients. The 2 patients who revealed no erection at all immediately after operation had dense adhesion of penile hilar region caused in one case by severe pelvic trauma and in the other by pubic bone fracture. Twenty-eight (93.3%) patients were found to sustain excellent erection within 3 months postoperatively. However, only 12 (40.0%) patients sustained spontaneous erection at long-term follow-up, while another 7 (23.3%) responded to intracavernous injection. It is worth mentioning that tortuous and marked dilation of the deep dorsal vein and/or cavernous veins were found intraoperatively in 6 patients who were observed to have excellent erections postoperatively. Inadequate elimination of the leakage veins, especially crural veins, is the most likely factor in those who had a recurrence of erectile dysfunction. However, the corpus cavernosum, particularly a myopathic condition or inadequate neurotransmitters, also plays an important role. Complications included shortness of penis (3 patients), penile deviation (3), numbness of glans penis (4) and wound infection (1).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7925529

A New Multimodal Biometric System Based on Finger Vein and Hand Vein Recognition  

Directory of Open Access Journals (Sweden)

Full Text Available As a reliable and robust biological characteristic, the vein pattern increases more and more the progress in biometric researches. Generally, it was shown that single biometric modality recognition is not able to meet high performances. In this paper, we propose a new multimodal biometric system based on fusion of both hand vein and finger vein modalities. For finger vein recognition, we employ the Monogenic Local Binary Pattern (MLBP, and for hand vein recognitionan Improved Gaussian Matched Filter (IGMF. Experimental results confirm that the proposed multimodal biometric process achieves excellent recognition performance compared to unimodal biometric system. The Area Under Curve (AUC of the proposed approach is very close to unity (0.98.

Transpositional reactivation of two LTR retrotransposons in rice-Zizania recombinant inbred lines (RILs).  

Science.gov (United States)

Hybridization is prevalent in plants, which plays important roles in genome evolution. Apart from direct transfer and recombinatory generation of genetic variations by hybridization, de novo genetic instabilities can be induced by the process per se. One mechanism by which such de novo genetic variability can be generated by interspecific hybridization is transpositional reactivation of quiescent parental transposable elements (TEs) in the nascent hybrids. We have reported previously that introgressive hybridization between rice (Oryza sativa L.) and Zizania latifolia Griseb had induced rampant mobilization of three TEs, a copia-like LTR retrotransposon Tos17, a MITE mPing and a class II TE belonging to the hAT superfamily, Dart/nDart. In this study, we further found that two additional LTR retrotransposons, a gypsy-like (named RIRE2) and a copia-like (named Copia076), were also transpositionally reactivated in three recombinant inbred lines (RILs) derived from introgressive hybridization between rice and Z. latifolia. Novel bands of these two retroelements appeared in the RILs relative to their rice parental line (cv. Matsumae) in Southern blot, suggestive of retrotransposition, which was substantiated by transposon display (TD) and locus-specific PCR amplification for insertion sites. Both elements were found to be transcribed but at variable levels in the leaf tissue of the parental line and the RILs, suggesting that transcriptional control was probably not a mechanism for their transpositional activity in the RILs. Expression analysis of four genes adjacent to de novo insertions by Copia076 revealed marked difference in the transcript abundance for each of the genes between the RILs and their rice parental line, but the alterations in expression appeared unrelated with the retroelement insertions.

Ligation of superior mesenteric vein and portal to splenic vein anastomosis after superior mesenteric-portal vein confluence resection during pancreaticoduodenectomy – Case report  

Science.gov (United States)

62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral circulation was diminished. Pancreaticoduodenectomy (PD) and superior mesenteric portal vein (SMPV) confluence resection were performed; A saphenous vein interposition graft thrombosed immediately. The splenic vein remnant was distended and adjacent to the stump of the portal vein. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. As a result, we chose to perform a direct anastomosis of the portal and splenic vein in a desperate situation. The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. The patient had an uneventful postoperative course, except transient ascites. She redeveloped ascites more than one year later. At that time a PET scan showed bilateral lung and right femur metastatic disease. She expired 15 months after PD. Conclusion The lessons we learned are (1) Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2) Synthetic graft is an alternative for internal jugular vein graft. (3) Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4) It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival.

The effects of strand transposition on the stiffness matrix of superconductor core elements  

International Nuclear Information System (INIS)

The axial and torsional components of the stiffness matrix of superconductor core elements are derived taking into account the effects of the wrapping of superconductor strands around the internal insulating strip. It is shown that the inclination of the strands referred to the longitudinal axis of the superconductor produces a reduction of the axial stiffness and a considerable increase in torsional stiffness. Examples relating to superconductors proposed for the NET Toroidal Field Coil are shown. In that instance the strand transposition is carried out by roebling

Bifocal stimulation in patient with congenitally corrected transposition of great vessels.  

Science.gov (United States)

Congenitally corrected transposition of the great vessels (CCTGV) is a rare congenital heart defect associated with multiple cardiac morphological abnormalities and conduction defects. Complete atrioventricular (AV) block occurs in 30% of patients and it may be present at birth or develop later with a rate of 2% per year; moreover, a systemic right ventricle is frequently characterized by heart failure in adult life. We used a bifocal cardiac stimulation for a young woman affected by CCTGV and atrioventricular Mobitz 2 and 2:1 block, considering structural, anatomic condition, and the high rate of pacing she underwent.

Composition of transpositions and equality of ribbon Schur Q-functions  

CERN Document Server

We introduce a new operation on skew diagrams called composition of transpositions, and use it to derive equalities on skew Schur Q-functions whose indexing shifted skew diagram is an ordinary skew diagram. When this skew diagram is a ribbon, we conjecture necessary and sufficient conditions for equality of ribbon Schur Q-functions. In addition, we determine all relations between ribbon Schur Q-functions and show that the non-commutative analogue of ribbon Schur Q-functions is the flag h-vector of Eulerian posets.

Recent developments of direct rhenium-catalyzed [1,3]-transpositions of allylic alcohols and their silyl ethers.  

Science.gov (United States)

The direct metal-catalyzed [1,3]-transposition of allylic alcohols and allylic silyl ethers is a synthetically useful isomerization process that occurs via [3,3]-sigmatropic rearrangement induced by high oxidation state oxometal complexes. The isomerization requires only a catalytic amount of promoter, and high chirality transfer can be achieved. Thus, it bears a significant potential to become a powerful tool in multistep synthesis. Although [1,3]-transposition of allylic alcohols has been known since the late 1960s, the development of synthetically useful protocols that allow for a high level of regio- and stereoselectivity control and their synthetic applications have emerged only recently. This tutorial review summarizes recently developed regioselective [1,3]-transpositions of allylic alcohols and silyl ethers and their applications to natural product synthesis. PMID:24759893

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

Directory of Open Access Journals (Sweden)

Full Text Available 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.

Technical aspects of adrenal vein sampling.  

Science.gov (United States)

The most common cause of secondary hypertension is primary aldosteronism, with a prevalence of approximately 30% when screened by specialized hypertension clinics. Adrenal venous sampling is considered the standard for reliably distinguishing between unilateral and bilateral hormone secretion, with unilateral secretion being surgically curable. Success of adrenal vein sampling relies on appropriate patient selection, patient preparation, and recognition and catheterization of both adrenal veins. However, this procedure may prove technically challenging, particularly for inexperienced operators. This video (see Fig; available online at www.jvir.org) is designed to provide the viewer with details on the technical aspects of adrenal vein sampling by using the sequential technique in an immersive format with real-time table-top teaching. Indications, patient preparation, equipment selection, technique, and quality assurance are reviewed in detail, with the goal of providing practitioners an opportunity to successfully incorporate this procedure into their practice.

CT angiography of the cerebral veins  

International Nuclear Information System (INIS)

Purpose: We report on our first experience in imaging the cerebral veins and sinuses with CT angiography (CTA). Material and methods: CTA was performed in 10 patients after bolus injection of contrast medium to rule out sinovenous thrombosis. Results: In 8 of 10 patients thrombosis of cerebral venous sinuses was ruled out by CTA. Sinovenous thrombosis was diagnosed and confirmed in two patients. In 5 cases, diagnosis of CTA was confirmed by MRI and/or DSA, in 5 other cases by the clinical course. CTA results in detailed information about flow and anatomy of cerebral veins due to high intravascular contrast. Conclusions: CTA is a suitable noninvasive method to study cerebral veins as it is superior to conventional CT because of high resolution and intravascular contrast. To assess the sensitivity of CTA for diagnosis of venous sinus thrombosis a prospective study is needed. (orig.)

The effects of kale (Brassica oleracea ssp. acephala), basil (Ocimum basilicum) and thyme (Thymus vulgaris) as forage material in organic egg production on egg quality.  

Science.gov (United States)

1. In organic egg production, forage material as part of the diet for laying hens is mandatory. The purpose of the present study was to examine the effect of feeding with forage materials including maize silage, herbs or kale on egg production and various egg quality parameters of the shell, yolk colour, egg albumen, sensory properties, fatty acid and carotenoid composition of the egg yolk. 2. A total of 5 dietary treatments were tested for 5 weeks, consisting of a basal organic feed plus 120?g/hen.d of the following forage materials: 1) maize silage (control), 2) maize silage incl. 15?g/kg basil, 3) maize silage incl. 30?g/kg basil, 4) maize silage incl. 15?g/kg thyme, or 5) fresh kale leaves. Each was supplied to three replicates of 20 hens. A total of 300 hens was used. 3. Feed intake, forage intake and laying rate did not differ with treatment, but egg weight and egg mass produced increased significantly with the kale treatment. 4. The egg shell strength tended to be higher with the kale treatment, and egg yolk colour was significantly more red with the kale treatment and more yellow with basil and kale treatments. The albumen DM content and albumen gel strength were lowest with the thyme treatment. By sensory evaluation, the kale treatment resulted in eggs with less sulphur aroma, higher yolk colour score, and more sweet and less watery albumen taste. Furthermore, the eggs of the kale treatment had significantly higher lutein and ?-carotene content. Also, violaxanthin, an orange xanthophyll, tended to be higher in kale and eggs from hens receiving kale. 5. In conclusion, forage material, especially basil and kale, resulted in increased egg production and eggs of high and differentiable quality. PMID:22646790

Optimal imaging technique for puerperal ovarian vein  

International Nuclear Information System (INIS)

The authors have compared the MR images of 14 patients with clinical suspicion of puerperal ovarian vein thrombosis (POVT) with the CT scans (six patients) and US studies (six patients). Of the four patients who had POVT, it was confirmed by other imaging modalities. US missed the diagnosis of POVT in one patient. CT was 100% sensitive, but falsely suggested POVT in one patient with pyelonephritis. The remaining 10 patients were discharged without anticoagulation; none of these patients developed subsequent ovarian vein thrombosis. The authors have concluded that MR imaging could separate the patients who require anticoagulation from those who do not and could evaluate disorders whose symptoms mimic POVT

Imaging of postpartum ovarian vein thrombosis.  

Science.gov (United States)

Postpartum ovarian vein thrombosis (OVT) is a rare but serious complication. Clinical findings of OVT are nonspecific. Postpartum OVT, which is a clinically difficultly diagnosed entity, must be thought of in differential diagnosis in cases of postpartum acute abdomen. OVT can be accurately diagnosed by appropriate noninvasive radiologic modalities to start early therapy with anticoagulants and intravenous antibiotics. In this paper, we review the imaging findings of a case with postpartum ovarian vein thrombosis that had been followed up for 6 months by ultrasonography (US), color Doppler US, computed tomography (CT), and magnetic resonance imaging (MRI).

It commonly affects the deep leg veins (such as the calf veins, femoral vein, or popliteal vein or the deep veins of the pelvis. It is a potentially dangerous condition that can lead to preventable morbidity and mortality.Aim: To present an update on the causes and management of DVT.Methods: A review of publications obtained from Medline search, medical libraries, and Google.Results: DVT affects 0.1% of persons per year. It is predominantly a disease of the elderly and has a slight male preponderance. The approach to making a diagnosis currently involves an algorithm combining pretest probability, D-dimer testing, and compression ultrasonography. This will guide further investigations if necessary. Prophylaxis is both mechanical and pharmacological. The goals of treatment are to prevent extension of thrombi, pulmonary embolism, recurrence of thrombi, and the development of complications such as pulmonary hypertension and post-thrombotic syndrome.Conclusion: DVT is a potentially dangerous condition with a myriad of risk factors. Prophylaxis is very important and can be mechanical and pharmacological. The mainstay of treatment is anticoagulant therapy. Low-molecular-weight heparin, unfractionated heparin, and vitamin K antagonists have been the treatment of choice. Currently anticoagulants specifically targeting components of the common pathway have been recommended for prophylaxis. These include fondaparinux, a selective indirect factor Xa inhibitor and the new oral selective direct thrombin inhibitors (dabigatran and selective factor Xa inhibitors (rivaroxaban and apixaban. Others are currently undergoing trials. Thrombolytics and vena caval filters are very rarely indicated in special circumstances.Keywords: deep vein thrombosis, pulmonary embolism, venous thromboembolism, prophylaxis, treatment

Changes in the content of total nitrogen and mineral nitrogen in the basil herb depending on the cultivar and nitrogen nutrition  

Directory of Open Access Journals (Sweden)

Full Text Available Among fundamental nutrients, nitrogen fertilization is considered one of the most effective factors affecting both the yield and the quality of plant material. Nitrogen form used for fertilizing is also of great importance. The aim of this study was to investigate the impact of nitrogen nutrition (calcium nitrate, ammonium nitrate, and urea as well as (green, purple, and‘Fino Verde’ on the chemical composition and yielding of basil (Ocimum basilicumL.. After drying the plant material at a temperature of 60°C and milling, total nitrogen was determined by means of Kjeldahl method, while mineral nitrogen content (N-NH 4, N-NO 3 was analyzed in 2% acetic acid extract. Yield of fresh basil matter depended significantly on the variety grown. The highest yields were obtained from a cultivar of ‘Fino Verde’ fertilized with ammonium nitrate. The purple variety plants fertilized with urea were characterized by a largest amount of total nitrogen. The‘Fino Verde’cultivar fertilized with urea accumulated the least quantities of nitrates in the basil herb.

Long-term follow-up of gracilis muscle transposition in children.  

Science.gov (United States)

Sixteen children of uncontrollable fecal incontinence have been treated with Pickrell's gracilis muscle transposition since 1983: 12 had an imperforate anuses with multiple corrective operative procedures and 4 had traumatic destructions of anal sphincters. We report a series of 11 cases whom we followed-up over a period of 0.8 to 10.5 years (mean; 5.6 years). Seven patients were evaluated by anorectal manometry. All patients except one who had left hemipelvectomy and permanent colostomy showed nearly normal continence during the follow-up period. There was no evidence of fibrosis in the transposed muscles and the tensions of the transposed muscles were well maintained. The voluntary contractions of the transposed muscles were well maintained and efficient in all cases. The general manometric parameters did not correlate well with the functional results; however, there was a strong correlation in the S/R ratio (maximum squeeze pressure/resting pressure) with the functional results. We believe that the good functional outcome of this procedure need not only the meticulous surgical technique but also the personal motivation and the compliance with physiotherapy. In conclusion, although the gracilis muscle transposition never results in normal continence, acceptable continence can be achieved in the selected patients. PMID:7483681

[Physiopathologic findings and surgical treatment in transposition of great vessels: our experience].  

Science.gov (United States)

Transposition of great vessels (TGV) is the most frequent neonatal cyanotic malformative cardiopathy. The Authors report their experience in surgical anatomical correction of transposition of the great arteries in 55 patients, 44 male and 11 female. Minimum age was 2 days, maximum 6 months. TGV was simple in 38 cases and associated with ventricular defect in 12 cases, with double outlet right ventricle in 3 cases, and with complex cardiopathy in 2 cases. There have been 11 deaths. The cause of death was: cardiac failure in 3 patients, myocardial infarct in 4 patients, respiratory insufficiency in 2 patients, and sepsis in 2 patients. There was one death by myocardial infarction and 1 asymptomatic ostial left coronary stenosis during follow-up (from 1 to 104 months). There were neither anastomotic pulmonary stenosis nor aortic valve incompetence. The authors review the literature on functional and anatomic correction of TGV and underline the importance of precocious anatomic together with early diagnosis, percutaneous atrioseptostomy and pharmacologic (PGE1) therapy in determining further reduction of mortality and to improve late outcome.

Construction of transposition insertion libraries and specific gene inactivation in the pathogen Lactococcus garvieae.  

Science.gov (United States)

This paper reports the development of genetic tools in Lactococcus garvieae, an important Gram-positive bacterial pathogen affecting both fish and mammals. The vector pGKV210, a broad host range vector, was introduced by electroporation into L. garvieae UNIUD074. The maximal frequency obtained was 3.2 x 10(5) transformants/mug of DNA. Moreover, this effect is highly reproducible and appears to be constant, since all L. garvieae strains tested were transformed. Once the optimal transformation procedure was established, it was used to generate isogenic and transposition mutants. Insertional mutagenesis of the L. garvieae SA9H10L gene, similar to a Streptococcus pyogenes gene encoding the M protein (emm64), was carried out using the conditional replication plasmid pORI19. Transposition mutagenesis using the streptococcal temperature-sensitive suicide vector pTV408 to deliver Tn917 into the chromosome of L. garvieae was also achieved at a frequency of ca. 10(-4). Transposon flanking DNA sequences were obtained by plasmid rescue in Escherichia coli and their sequencing analysis demonstrated that the transposon was inserted at different chromosomal loci. Tn917 also made it possible to select a mutant in the operon involved in mannitol fermentation in this microorganism. The results obtained in the present study lay the foundation for future research on the virulence mechanisms of L. garvieae. PMID:16797929

Letter transpositions within and across morphemic boundaries: is there a cross-language difference?  

Science.gov (United States)

Research on the impact of letter transpositions that arise across morpheme boundaries has yielded conflicting results. These results have led to the suggestion that a cross-linguistic difference may exist in the recognition of Spanish and English words. In two masked-priming experiments run on separate groups of Spanish and English speakers, we tested this hypothesis by comparing the impacts of primes with letter transpositions that arose within morphemes or across morpheme boundaries on the recognition of identical or near-identical Spanish-English cognate targets. The results showed transposed-letter benefits in both Spanish and English that were not modulated by the position of the transposed letter in the prime stimulus. Our findings therefore add to the growing body of literature suggesting that the transposed-letter benefit is not affected by the position of the transposed letters relative to the morpheme boundary, and they dispel previous suggestions that there might be a genuine difference in orthographic coding across the Spanish and English writing systems.

Ribosomal DNA locus evolution in Nemesia: transposition rather than structural rearrangement as the key mechanism?  

Science.gov (United States)

We investigated chromosome evolution in Nemesia using fluorescent in-situ hybridization (FISH) to identify the locations of 5S and 45S (18-26S) ribosomal genes. Although there was conservation between Nemesia species in chromosome number, size and centromere position, there was large variation in both number and position of ribosomal genes in different Nemesia species (21 different arrangements of 45S and 5S rRNA genes were observed in the 29 Nemesia taxa studied). Nemesia species contained between one and three pairs of 5S arrays and between two and four pairs of 45S arrays. These were either sub-terminally or interstitially located and 45S and 5S arrays were often located on the same chromosome pair. Comparison of the positions of rDNA arrays with meiotic chromosome behaviour in interspecific hybrids of Nemesia suggests that some of the changes in the positions of rDNA have not affected the surrounding chromosome regions, indicating that rDNA has changed position by transposition. Chromosome evolution is frequently thought to occur via structural rearrangements such as inversions and translocations. We suggest that, in Nemesia, transposition of rDNA genes may be equally if not more important in chromosome evolution. PMID:17195054

A veia braquial comum apr [...] esenta-se como uma alternativa plausível e pouco conhecida. OBJETIVO: Descrever a anatomia da veia braquial comum como via de drenagem colateral no membro superior. MÉTODOS: Utilizamos 30 cadáveres do sexo masculino, cujos membros superiores estavam articulados ao tronco, não importando a raça, formolizados e mantidos em conservação com solução de formol a 10%. Utilizamos como critérios de exclusão cadáveres com um dos membros desarticulado ou alterações deformantes em topografia das estruturas estudadas. RESULTADOS: A veia braquial comum esteve presente em 73% (22/30) dos cadáveres estudados, sendo que em 18% (04/22) dos casos drenou para a veia basílica no seguimento proximal do braço e em 82% (18/22), para a veia axilar. CONCLUSÃO: A veia braquial comum está frequentemente presente e, na maior parte das vezes, desemboca na veia axilar. Abstract in english BACKGROUND: Trauma and thrombosis that can result in changes in the venous drainage of the upper limb, depending on the vascular territory interrupted, may have as a compensatory mechanism a collateral drainage channel that prevents damage to the venous return of that limb. The common brachial vein [...] is a plausible and little known collateral channel for this purpose. OBJECTIVE: To describe the anatomy of the common brachial vein as a collateral drainage channel of the upper limb. METHODS: We have dissected 30 cadavers of people of different races, whose upper limbs were articulated to the trunk and preserved in a 10% formaldehyde solution. The exclusion criteria were disarticulated limbs or deformities in the topography of the studied structures. RESULTS: The common brachial vein was present in 73% (22/30) of the cadavers dissected. The common brachial vein drained into the axillary vein in 82% (18/22) and into the basilic vein in the proximal segment of the upper limb in 18% of the cadavers (04/22). CONCLUSION: The common brachial vein is frequently present, and, in most cases, it drains into the axillary vein.

Varicose veins: role of mechanotransduction of venous hypertension.  

Science.gov (United States)

Varicose veins affect approximately one-third of the adult population and result in significant psychological, physical, and financial burden. Nevertheless, the molecular pathogenesis of varicose vein formation remains unidentified. Venous hypertension exerted on veins of the lower extremity is considered the principal factor in varicose vein formation. The role of mechanotransduction of the high venous pressure in the pathogenesis of varicose vein formation has not been adequately investigated despite a good progress in understanding the mechanomolecular mechanisms involved in transduction of high blood pressure in the arterial wall. Understanding the nature of the mechanical forces, the mechanosensors and mechanotransducers in the vein wall, and the downstream signaling pathways will provide new molecular targets for the prevention and treatment of varicose veins. This paper summarized the current understanding of mechano-molecular pathways involved in transduction of hemodynamic forces induced by blood pressure and tries to relate this information to setting of venous hypertension in varicose veins.

Semi-field cage studies on the evaluation of basil oil as an attractant for male Mediterranean fruit fly, Ceratitis capitata (Wied.)  

International Nuclear Information System (INIS)

The Sterile Insect Technique (SIT) is an environmentally benign approach for suppressing or eradicating insect pests and is widely used in integrated programmes against tephritid fruit fly pests, particularly the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) Ecological studies of fruit flies have long depended on the methods developed for trapping the fly in the field. The improvement of attractant lures for fruit flies has become a great tool for population suppression before starting a programme integrating the SIT and as a monitor tool during the programme. Moreover, the attractant can be used to induce artificial aggregation of sterile and wild males and mating can be observed at these sites. In 1998, laboratory tests conducted in Egypt, demonstrated that basil oil can be used as attractant for male medfly. The present study deals with the evaluation of basil oil as an attractant for fertile wild type males (EGII Strain), as well as irradiated and non-irradiated mass-reared males from a genetic sexing strain based on a temperature sensitive lethal (tsl) mutation (Vienna-7 mix). The males were tested in field cages located at the FAO/ IAEA Agriculture and Biotechnology Laboratory (Seibersdorf, Austria). Baited Jackson traps were used for attraction of males. The results of the first experiment showed that, for 24 hours, the basil oil attracted 67% of the non- irradiated V-7 mix males, while only 54% of the irradiated (100 Gy) of V-7 mix males were attractted (100 Gy) of V-7 mix males were attracted. A different field cage was used for each of the irradiated and non-irradiated males. The second experiment showed that, 65% of the fertile wild medfly males (EGII) were attracted, while only 32% of the irradiated V-7 mix males were attracted. Both types of males were contained in one cage. The data obtained has shown that basil oil can be used as medfly attractant instead of the very expensive trimedlure, normally used for this purpose. Open field test should be conduced to complete the evaluation of basil oil as a medfly attractant

Evaluation of left renal vein entrapment using multidetector computed tomography  

International Nuclear Information System (INIS)

Background: Nutcracker syndrome, also called left renal vein entrapment syndrome, is a cause of non-glomerular hematuria with difficulties in diagnosis. Multidetector computed tomography (MDCT) is a powerful tool to prevent unnecessary diagnostic procedures. Purpose: To retrospectively determine the prevalence of nutcracker phenomenon and nutcracker syndrome seen in MDCT in consecutive patients. Material and Methods: The institutional review board approved the study and waived the requirement for informed consent. Abdominal contrast-enhanced MDCT scans were reviewed from 1000 consecutive patients. MDCT scan assessment included renal vein diameter measurements and evaluation for the presence of anterior or posterior left renal vein entrapment. Electronic medical records and urine analysis reports of patients with left renal vein entrapment were reviewed. Student's t test was used to assess differences in renal vein diameter in patients with left renal vein entrapment. Results: Left renal vein entrapment was observed in 10.9% (109), retroaortic left renal vein in 6.5% (65), entrapment of left renal vein between superior mesenteric artery and aorta in 4.1% (41), and circumaortic left renal vein in 0.3% (3) of patients. Mean diameters of right (8.8 ± 1.9 mm) and unentrapped left (8.9 ± 1.8 mm) renal veins were not significantly different (P = 0.1). The mean diameter of anterior entrapped left renal veins (10.3 ± 2 mm) was significantly greater (P = 0.04) than contralatantly greater (P = 0.04) than contralateral renal veins (8.6 ± 2.1 mm) in their widest portion. In 8.8% of patients with the left renal vein entrapment, urine analysis showed isomorphic hematuria or proteinuria with no other known cause. Varicocele and pelvic congestion were seen in 5.5% of patients with the left renal vein entrapment. Conclusion: Left renal vein entrapment is not a rare entity and renal nutcracker phenomenon might be underdiagnosed

Venous thrombosis may be fatal, for example by a pulmonary embolism and right or left atrial thrombosis. Alternatively, deep vein thrombosis may follow a benign pattern such as femoral and popliteal vein thrombosis. Internal Jugular vein (IJV) thrombosis is a rare entity. Internal jugular vein thrombosis is a serious event with potentially fatal outcome, where the clinical symptoms may be vague or absent. It is usually secondary to various etiologies such as catheter, malignancy, trauma, infe...

Comparison between mechanical properties of human saphenous vein and umbilical vein  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background As a main cause of mortality in developed countries, Coronary Artery Disease (CAD is known as silent killer with a considerable cost to be dedicated for its treatment. Coronary Artery Bypass Graft (CABG is a common remedy for CAD for which different blood vessels are used as a detour. There is a lack of knowledge about mechanical properties of human blood vessels used for CABG, and while these properties have a great impact on long-term patency of a CABG. Thus, studying these properties, especially those of human umbilical veins which have not been considered yet, looks utterly necessary. Methods Umbilical vein, as well as human Saphenous vein, are respectively obtained after cesarean and CABG. First, histological tests were performed to investigate different fiber contents of the samples. Having prepared samples carefully, force-displacement results of samples were rendered to real stress–strain measurements and then a fourth-order polynomial was used to prove the non-linear behavior of these two vessels. Results Results were analyzed in two directions, i.e. circumferentially and longitudinally, which then were compared with each other. The comparison between stiffness and elasticity of these veins showed that Saphenous vein’s stiffness is much higher than that of umbilical vein and also, it is less stretchable. Furthermore, for both vessels, longitudinal stiffness was higher than that of circumferential and in stark contrast, stretch ratio in circumferential direction came much higher than longitudinal orientation. Conclusion Blood pressure is very high in the region of aorta, so there should be a stiff blood vessel in this area and previous investigations showed that stiffer vessels would have a better influence on the flow of bypass. To this end, the current study has made an attempt to compare these two blood vessels’ stiffness, finding that Saphenous vein is stiffer than umbilical vein which is somehow as stiff as rat aortic vessels. As blood vessel’s stiffness is directly related to elastin and mainly collagen content, results showed the lower amount of these two contents in umbilical vein regarding Saphenous vein.

Outpatient consent practice for varicose vein surgery  

Directory of Open Access Journals (Sweden)

Full Text Available Azzam Al-Amin, Muhammad Faiz Taib, Yousif Aawsaj, Asad RahiEast Lancashire Healthcare Trust, Department of Vascular Surgery, Royal Blackburn Hospital, Blackburn, United KingdomBackground: The aims of this study were to assess the accuracy and completeness of current consent practice in an outpatient clinic for open and minimally invasive varicose vein surgery, and to ascertain the type of complications suffered by patients and their correlation with consent practice.Methods: This was a retrospective analysis of outpatient consent practice from January to December 2010. All patients undergoing varicose vein surgery by open or endovenous laser therapy under a single consultant were identified. Case notes were examined by looking at clinic letters and consent forms, which were assessed against current standards.Results: Over 12 months, 103 consecutive patients were analyzed, and comprised 69 undergoing open surgery and 34 undergoing endovenous laser therapy. In total, 91% of patients were consented by a consultant, 6% by a senior house officer, and 3% by a registrar. For open surgery, all patients were consented for bruising, infection, numbness, nerve damage, and deep vein thrombosis. Only 43% were consented for pain; 2.76% were suffering pain and 6% were consented for thrombophlebitis without suffering. All patients who underwent endovenous laser therapy were consented for pain, numbness, skin discoloration, thrombophlebitis, nerve damage, and deep vein thrombosis. Only 8.8% were consented for infection and 2.9% suffered. No patients were consented for skin burns.Conclusion: Different strategies should be considered to improve the consent process and avoid the withholding of apparently trivial but crucial information during consenting.Keywords: consent, litigation, outpatient, varicose veins

MR venography of the inferior mesentery vein  

International Nuclear Information System (INIS)

Objective: To evaluate on three-dimensional (3D) dynamic contrast-enhanced (DCE) MR venography (MRV), the visibility of the inferior mesenteric vein (IMV), its insertion pattern into the portal system, and the difference of IMV diameters between healthy subjects and patients with cirrhosis. Materials and methods: Two hundred and seventeen consecutive patients who had abdominal 3D DCE MRI was included in this study. The original image data of 3D DCE MRI was used to generate multiple planar volume reconstruction (MPVR) images, which were evaluated for visualization of the IMV and its pattern of insertion into the portal system. The diameter of IMV was measured and compared in 24 patients with cirrhosis (Cirrhosis Group) and in 30 patients without hepatic lesions or liver disease (Healthy Group). Results: In the 217 patients, the frequencies of visualization of IMV, grade 1 order branches and grade 2 order branches were, respectively, 88%, 24% and 9%. The IMV inserted into the splenic vein (SV), the portal confluence and the superior mesenteric vein (SMV) in 45%, 18% and 37%, respectively. Among patients with cirrhosis, 12.5% had IMV diameter larger than 5.1 mm, although there was no significant difference between cirrhosis and healthy groups (P > 0.05). However, the diameters of the main portal vein (MPV), SV and SMV were significantly larger in the Cirrhosis Group (P < 0.05). Conclusion: The IMV and its branches can be depicted well by 3D DCE MRV. The most common inser well by 3D DCE MRV. The most common insertion of the IMV is into the splenic vein. A minority of patients with cirrhosis had dilatation of the IMV

Vein thromboembolism prevention in stroke patients  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction Having in mind the rate of occurrence and clinical importance, venous thromboembolism implies venous thrombosis and pulmonary embolism as a result of embolisation of the thrombotic particles from deep veins or pelvic veins. Venous thrombosis of the deep veins may result in chronic vein insufficiency, but the primary medical problem is the possibility of development of pulmonary embolism which may cause permanent respiratory function damage or even fatal outcome. Venous thromboembolism prevention in stroke The high incidence of deep vein thrombosis (30% clinically and up to 50% subclinically in acute stroke hemiparetic and bed ridden patients within two weeks from the onset and 1-2% pulmonary embolism with the fatal outcome in the first month clinically and 17% of all fatal outcomes in postmortem investigations present a necessity for the early venous thromboembolism prevention. On the other hand, the most powerful prevention strategy - anticoagulation has important limitations in acute stroke patients: almost impossible to be used in cerebral haemorrhage and a great risk for the development of hemorrhagic transformation in cerebral infarction. The fact that other prevention strategies have limited value requires an estimation of efectivity-risk ratio in venous thromboembolism prevention in stroke. Conclusion Venous thromboembolism prevention in stroke patients is necessary because of a greater risk for venous thromboembolism in these patients according to the nature of illness and functional disability, but also a problem because of limited possibility to recommend the proper medicament according to the risk of serious complications. The necessity of preventing venous thromboembolism and estimation of efficiency-risk ratio in stroke patients, beside plenty of studies and consensus conferences, remain individual and often very difficult.

Total anomalous pulmonary venous connection with descending vertical vein: Unusual drainage to azygos vein  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Most patients with total anomalous pulmonary venous connection have a set pattern of pulmonary venous drainage and predictable sites of obstruction. However, uncommon variations do exist and delineating the entire course is more important than just knowing the site of drainage. Azygos vein involvement in the circuit is nearly always associated with a complicated course, as was seen in our patient. This report reviews the drainage patterns when azygos vein forms a part of the circuit.

Absence of the right iliac vein and an unusual connection between both common femoral veins.  

Science.gov (United States)

The aim of the study is to report a case of a rare congenital anomaly of the venous system and to emphasize its clinical importance. We describe a case of aplasia of the right common and external iliac veins in a healthy seven-year-old boy who was referred for Doppler ultrasound examination for further evaluation of an abnormal varicosity in the suprapubic region. Colour Doppler ultrasound revealed a dilated, arch-shaped vein. Contrast-enhanced magnetic resonance angiography showed the absence of the right common iliac vein and external iliac vein. It also clearly demonstrated the aberrant venous structure, originating from the right common femoral vein and draining to the left common femoral vein. In conclusion, in our case, the patient’s life was threatened because the aberrant venous connection crossing within subcutaneous fatty tissue was not protected from external trauma and possible abdominal surgical interventions. Additional attention should be given to avoid such injuries, which can cause significant haemorrhage. PMID:22431769

Internal vein texture and vein evolution of the epithermal Shila-Paula district, southern Peru  

Science.gov (United States)

The epithermal Shila-Paula Au-Ag district is characterized by numerous veins hosted in Tertiary volcanic rocks of the Western Cordillera (southern Peru). Field studies of the ore bodies reveal a systematic association of a main E-W vein with secondary N55-60°W veins—two directions that are also reflected by the orientation of fluid-inclusion planes in quartz crystals of the host rock. In areas where this pattern is not recognized, such as the Apacheta sector, vein emplacement seems to have been guided by regional N40°E and N40°W fractures. Two main vein-filling stages are identified. stage 1 is a quartz-adularia-pyrite-galena-sphalerite-chalcopyrite-electrum-Mn silicate-carbonate assemblage that fills the main E-W veins. stage 2, which contains most of the precious-metal mineralization, is divided into pre-bonanza and bonanza substages. The pre-bonanza substage consists of a quartz-adularia-carbonate assemblage that is observed within the secondary N45-60°W veins, in veinlets that cut the stage 1 assemblage, and in final open-space fillings. The two latter structures are finally filled by the bonanza substage characterized by a Fe-poor sphalerite-chalcopyrite-pyrite-galena-tennantite-tetrahedrite-polybasite-pearceite-electrum assemblage. The ore in the main veins is systematically brecciated, whereas the ore in the secondary veins and geodes is characteristic of open-space crystallization. Microthermometric measurements on sphalerite from both stages and on quartz and calcite from stage 2 indicate a salinity range of 0 to 15.5 wt% NaCl equivalent and homogenization temperatures bracketed between 200 and 330°C. Secondary CO2-, N2- and H2S-bearing fluid inclusions are also identified. The age of vein emplacement, based on 40Ar/39Ar ages obtained on adularia of different veins, is estimated at around 11 Ma, with some overlap between adularia of stage 1 (11.4±0.4 Ma) and of stage 2 (10.8±0.3 Ma). A three-phase tectonic model has been constructed to explain the vein formation. Phase 1 corresponds to the assumed development of E-W sinistral shear zones and associated N60°W cleavages under the effects of a NE-SW shortening direction that is recognized at Andean scale. These structures contain the stage 1 ore assemblage that was brecciated during ongoing deformation. Phase 2 is a reactivation of earlier structures under a NW-SE shortening direction that allowed the reopening of the preexisting schistosity and the formation of scarce N50°E-striking S2-cleavage planes filled by the stage 2 pre-bonanza minerals. Phase 3 coincides with the bonanza ore emplacement in the secondary N45-60°W veins and also in open-space in the core of the main E-W veins. Our combined tectonic, textural, mineralogical, fluid-inclusion, and geochronological study presents a complete model of vein formation in which the reactivation of previously formed tectonic structures plays a significant role in ore formation.

Comparative studies on the activity of basil--an essential oil from Ocimum basilicum L.--against multidrug resistant clinical isolates of the genera Staphylococcus, Enterococcus and Pseudomonas by using different test methods.  

Science.gov (United States)

The essential oil basil is obtained from the aerial parts of Ocimum basilicum L. After gas chromatographic separation, the following components were identified: linalol (54.95%), methylchavikol (11.98%), methylcinnamat (7.24%) and linolen (0.14%). The activity of basil against multidrug resistant clinical isolates from the genera Staphylococcus, Enterococcus and Pseudomonas has been studied. For this purpose, standard and modified broth macrodilution methods were used and time kill kinetic of basil was studied. The minimum inhibitory concentrations (MICs) were reported between 0.0030% and 0.0007% (v/v). These concentrations were compared with the inhibitory concentrations (ICs) and the logs of the bacterial counts reduction both obtained by basil diluted in 1% Tween (Tw) 80, saline test solution (STS) and spiritus vini (Sv) 95 degrees instead in a broth. The data, obtained after application of different methods of investigation and validated with membrane filtration, showed a strong inhibitory effect of basil on the test bacteria. The chosen bacteria are widespread and pose serious therapeutic difficulties because of their high level of resistance. For this reason, the results obtained were considered encouraging.

Ocimum sanctum L (Holy Basil or Tulsi) and its phytochemicals in the prevention and treatment of cancer.  

Science.gov (United States)

Ocimum sanctum L. or Ocimum tenuiflorum L, commonly known as the Holy Basil in English or Tulsi in the various Indian languages, is a important medicinal plant in the various traditional and folk systems of medicine in Southeast Asia. Scientific studies have shown it to possess antiinflammatory, analgesic, antipyretic, antidiabetic, hepatoprotective, hypolipidemic, antistress, and immunomodulatory activities. Preclinical studies have also shown that Tulsi and some of its phytochemicals eugenol, rosmarinic acid, apigenin, myretenal, luteolin, ?-sitosterol, and carnosic acid prevented chemical-induced skin, liver, oral, and lung cancers and to mediate these effects by increasing the antioxidant activity, altering the gene expressions, inducing apoptosis, and inhibiting angiogenesis and metastasis. The aqueous extract of Tulsi and its flavanoids, orintin, and vicenin are shown to protect mice against ?-radiation-induced sickness and mortality and to selectively protect the normal tissues against the tumoricidal effects of radiation. The other important phytochemicals like eugenol, rosmarinic acid, apigenin, and carnosic acid are also shown to prevent radiation-induced DNA damage. This review summarizes the results related to the chemopreventive and radioprotective properties of Tulsi and also emphasizes aspects that warrant future research to establish its activity and utility in cancer prevention and treatment.

Complexation of estragole as pure compound and as main component of basil and tarragon essential oils with cyclodextrins.  

Science.gov (United States)

Inclusion complexes of estragole (ES) as pure compound and as main component of basil and tarragon essential oils (EOs) with ?-cyclodextrin (?-CD), ?-cyclodextrin (?-CD), hydroxypropyl-?-cyclodextrin (HP-?-CD), randomly methylated-?-cyclodextrin (RAMEB), a low methylated-?-cyclodextrin (CRYSMEB) and ?-cyclodextrin (?-CD) were characterized. Formation constants (Kf) of the complexes were determined in aqueous solution by nonlinear regression analysis using static headspace gas chromatography (SH-GC) and UV-visible spectroscopy. Solid inclusion complexes were prepared by the freeze-drying method for different CD:ES molar ratios and were characterized by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR). Inclusion complexes formation allowed the controlled release of ES. Moreover, increased DPPH radical scavenging activity and photostability of ES and ES containing EOs (ESEOs) were observed in the presence of CDs. These findings suggest that encapsulation with CDs could be an efficient tool to improve the use of ES and ESEOs in aromatherapy, cosmetic and food fields. PMID:25542121

Undergraduate Sustainable Learning: Effects of Sustainable Soilless Media on Production and Sensory Evaluation of Cucumbers, Basil, Parsley, and Lettuce  

Directory of Open Access Journals (Sweden)

Full Text Available Modern greenhouse production has been ~100% reliant on fossil fuels for all inputs (glazing, heating, fertilization, lighting, post-harvest. Recent innovations may reduce fossil fuel dependence but their effectiveness may not be thoroughly tested. To promote education in sustainable production, undergraduate students in Greenhouse Management class (Hort 3002W; University of Minnesota tested the effectiveness of two organic or ‘sustainable’ soilless media (Sunshine Natural and Organic Growing Mix, Sungro Metro-Mix Special Blend with a control (Sunshine LC8 Professional for crop production (height, leaf/flower number, yield and sensory evaluations (appearance, texture, taste, purchase of cucumbers (‘Big Burpless Hybrid’, ‘Sweet Burpless Hybrid’, basil (‘Opal Purple’, ‘Redleaf’, parsley (‘Green River’, ‘Extra Curled Dwarf’, ‘Hamburg’, and lettuce (Flying Saucer ‘Green’, ‘Red’. Significant differences between sustainable vs. control soils occurred for plant growth, depending on vegetative or reproductive traits, crops, and cultivars. These differences occasionally disappeared for sensory evaluation of edible components. In most crops, however, cultivars were highly significant factors. Undergraduate research can be used to provide directionality for future vegetable and herb plant breeding to focus on creating cultivars with increased yield and high consumer acceptance when grown in sustainable greenhouse soilless mixes.

Transposition and national level resources – Introducing the Cross Border Health Care Directive in Eastern Europe  

DEFF Research Database (Denmark)

Several recent papers have summarised the status of EU implementation studies. In this paper we suggest that the issue of sector specific resources has received too little attention in previous studies. Sector specific resources include “health sector resources” and “state administrative resources”. Our theoretical contribution is thus to add an explicit and more detailed concern for "sector specific resources" in national transposition. This can refine the understanding of resources, for example in the multi-variable models that are emerging as the state of the art in the field of EU implementation studies. To illustrate these points we have chosen an empirical design focusing on a directive with a potentially high impact on system resources and several ambiguous components (the Cross Border Health Care Directive). We have further chosen to focus on two Eastern European countries (Bulgaria and Poland), where limited resources within their health care systems are an important concern.

Grasping the experience of the other from an interview: : Self-transposition in use  

DEFF Research Database (Denmark)

This article describes a part of the interview process that is never usually reported. Listening to what people say is the key to increasing our knowledge of human existences. Procuring knowledge about human experience is much more challenging. Although good sources on how to prepare and conduct an interview exist, the process of the interviewer’s perception of the interviewee’s message and meaning is less examined. Beyond the role of eliciting the data, the researcher endeavours to reproduce the interviewee’s narration and not the voice of the researcher. By illustrating the process during the interview, further transparency and thereby validity may be achieved. To exemplify this, the perception of the interviewer is explored, and here Heidegger’s work on self-transposition has proved to be helpful.

Emergence of giant cycles and slowdown transition in random transpositions and $k$-cycles  

CERN Document Server

Consider the random walk on the permutation group obtained when the step distribution is uniform on a given conjugacy class. It is shown that there is a critical time at which two phase transitions occur simultaneously. On the one hand, the random walk slows down abruptly (i.e., the acceleration drops from 0 to -\\infty at this time as n tends to \\infty). On the other hand, the largest cycle size changes from microscopic to giant. The proof of this last result is both considerably simpler and more general than in a previous result of Oded Schramm (2005) for random transpositions. It turns out that in the case of random k-cycles, this critical time is proportional to 1/[k(k-1)], whereas the mixing time is known to be proportional to 1/k.

Klippel-Feil syndrome and levo-looped transposition of the great arteries.  

Science.gov (United States)

Klippel-Feil syndrome is a skeletal disorder characterised by low hairline and a short neck due to abnormal fusion of two or more cervical vertebrae. Although congenital heart and lung defects are infrequent, some abnormalities such as cor triatriatum, coarctation of the aorta, total anomalous pulmonary venous connection, or lung agenesis have been reported. The challenge of recognising Klippel-Feil syndrome lies in the fact that there is an association of this syndrome with other significant conditions such as skeletal, genitourinary, neurological, ear, and some cardiac defects. We report a Klippel-Feil syndrome type III 14-year-old patient with a levo-looped transposition of the great arteries. In addition, the patient had agenesis of the left upper-lung lobe.

Partial transposition of random states and non-centered semicircular distributions  

CERN Document Server

Let W be a Wishart random matrix of size d^2 times d^2, considered as a block matrix with d times d blocks. Let Y be the matrix obtained by transposing each block of W. We prove that the empirical eigenvalue distribution of Y approaches a non-centered semicircular distribution when d tends to indinity. The proofs are based on the moments method. This matrix model is relevant to Quantum Information Theory and corresponds to the partial transposition of a random induced state. We show for example that a mixed state on C^d tensor C^d, obtained after tracing out a random pure state over some ancilla, is typically PPT (hence undistillable) for large d, whenever the dimension of the ancilla exceeds Cd^2 for some constant C (conjecturally, C=4).

Museographic transposition : The development of a museum exhibit on animal adaptations to darkness  

DEFF Research Database (Denmark)

Science museums define the objectives of their exhibitions in terms of visitor learning outcomes, yet exhibition engineering staff lack theoretical and empirical research findings on which to base the creation of these educational environments. Here, a first step towards providing such research is reported. Museographic transposition was used as an analytical framework to investigate the development of an existing museum exhibit on animal adaptations to darkness. The analysis yielded a descriptive model of exhibition engineering as a three-stage process in which simultaneous processes of epistemological development and museum-pedagogical development result in the curatorial brief which forms the basis of the subsequent museographic development of the physical exhibit. Examples are discussed which illustrate the use of the model in identifying exhibition inconsistencies, but also in generating new ideas for exhibition engineering. The potential for further developing the model is discussed.

[Jugular vein thrombosis, subclavian vein thrombosis and right brachiocephalic vein thrombosis after in vitro fertilization and embryo transfer: a case report].  

Science.gov (United States)

To discuss the diagnosis and treatment of jugular vein thrombosis, subclavian vein thrombosis and the right brachiocephalic vein thrombosis after in vitro fertilization and embryo transfer (IVF-ET)cycles in clinical practice. The clinical data regarding a case of jugular vein thrombosis, subclavian vein and the right brachiocephalic vein thrombosis in IVF-ET were reviewed. Clinical characteristics, prevention and treatment of jugular vein thrombosis, subclavian vein and the right brachiocephalic vein thrombosis in IVF-ET were discussed. A woman with secondary infertility underwent an IVF cycle with prolonged protocol controlled ovarian hyperstimulation. The oestradial concentration was 2 495 pg/mL on the day of human chorionic goeadotrophin (hCG). Fifteen occytes were retrieved and 2 embryos were transferred. Nine days after the embryos were transferred, the patient had ascites,hydrothorax and fluid of pelvic cavity accumulating, and was hospitalized. The patient underwent volume expansion and paracentesis, and left the hospital 30 days after the embryo transfer. Her right neck had pain 43 days after the embryo transfer. B ultrasound showed jugular vein thrombosis, subclavian vein and the right brachiocephalic vein thrombosis. The patient underwent low molecular weight heparin anticoagulation and low molecular weight dextran expansion, and left hospital with symptoms improved. She had Caesarean section and had a healthy baby girl. The thrombosis in the IVF-ET was a rare and serious complication. Prevention of ovarian hyperstimulation syndrome (OHSS) may reduce the incidence. The patients had local pain, swelling, skin temperature increased, headache, neck pain, and had to be checked to determine whether there were blood clots. The main treatment was low molecular weight heparin anticoagulation and low molecular weight dextran expansion. Timely Cesarean section is recommended to ensure the safety of perinatal mother and child. PMID:21685703

Development of HIFU Therapy System for Lower Extremity Varicose Veins  

International Nuclear Information System (INIS)

High-intensity focused ultrasound (HIFU) treatment utilizing microbubbles was investigated in the present study. It is known that microbubbles have the potential to enhance the heating effects of an ultrasound field. In this study, the heat accompanying microbubble oscillation was used to occlude varicose veins. Alteration of veins was observed after ultrasound irradiation. Veins were resected by stripping. In this study, two vein conditions were adopted during HIFU irradiation; non-compressed and compressed. Compressing the vein was expected to improve occlusion by rubbing the altered intima under compressed conditions. The frequency of the ultrasound was 1.7 MHz, the intensity at the focus was 2800 W/cm2, and the irradiation time was 20 s. In this study, the contrast agent Levovist registered was chosen as a microbubble source, and the void fraction (ratio of total gas volume to liquid) in the vein was fixed at 10-5. Under non-compressed conditions, changes were observed only at the adventitia of the vein anterior wall. In contrast, under compressed conditions, changes were observed from the intima to the adventitia of both the anterior and posterior walls, and they were partly stuck together. In addition, more experiments with hematoxylin-eosin staining suggested that the changes in the vein were more substantial under the latter conditions. From these results, it was confirmed that the vein was occluded more easily with vein compression.ed more easily with vein compression.

Finger vein recognition with personalized feature selection.  

Science.gov (United States)

Finger veins are a promising biometric pattern for personalized identification in terms of their advantages over existing biometrics. Based on the spatial pyramid representation and the combination of more effective information such as gray, texture and shape, this paper proposes a simple but powerful feature, called Pyramid Histograms of Gray, Texture and Orientation Gradients (PHGTOG). For a finger vein image, PHGTOG can reflect the global spatial layout and local details of gray, texture and shape. To further improve the recognition performance and reduce the computational complexity, we select a personalized subset of features from PHGTOG for each subject by using the sparse weight vector, which is trained by using LASSO and called PFS-PHGTOG. We conduct extensive experiments to demonstrate the promise of the PHGTOG and PFS-PHGTOG, experimental results on our databases show that PHGTOG outperforms the other existing features. Moreover, PFS-PHGTOG can further boost the performance in comparison with PHGTOG. PMID:23974154

Lower extremity dep vein thrombosis in children  

International Nuclear Information System (INIS)

Of 113 leg venograms performed in patients of all ages between 1969 and 1982, 68 were in children 16 years old or less. The patients were all studied on a tilt table (method of Rabinov and Paulin) in a head-up, 40-500 incline without tourniquets, supporting their weight on the unaffected leg. Among the 68 venograms, 12 (18%) were positive for deep vein thrombosis. The clinical settings for thrombosis in children were post-catheterization (two patients), post surgery (two), tumor/tumor therapy (three), drug abuse (one), and idiopathic (three). There were no long-term clinical sequelae in five patients. Pulmonary infarction occurred in three, and three patients required either long-term anticoagulation or IVC clipping. Clinical diagnosis is no more accurate for the diagnosis of deep vein thrombosis in children than it is in adults. Venography is the best method for making an accurate diagnosis and directing subsequent therapy.(orig.)

Inadvertent port: catheter placement in azygos vein.  

Science.gov (United States)

Totally implantable ports are safe and effective means of venous access for administration of chemotherapy. One of the usual vessels accessed, through which the port is placed, is the subclavian. Herein, we report a case where the central access was obtained through the left subclavian vein. But the catheter when it was placed was found to be in the azygos vein. This was confirmed with dye study. This is the first report of such an occurrence with subclavian access. The catheter was later withdrawn and repositioned in the superior vena cava. We recommend that the entire procedure of catheter placement must be done under fluoroscopy guidance to ensure safe and error-free positioning. PMID:23730139

Dilated vein of Galen in Kabuki syndrome.  

Science.gov (United States)

Kabuki syndrome (KS) comprises multiple congenital abnormalities and is characterized by a peculiar facial appearance, dermatoglyphic anomalies, mental retardation, skeletal abnormalities and postnatal growth retardation. We describe the case of a 23-month-old boy with the typical features of KS who had several malformations in the veins of the brain, which had not previously been described in patients with this syndrome. The MRI phlebogram of this patient showed that the vein of Galen was dilated and that it drained anomalously. The sinus rectus was abnormal and the longitudinal inferior venous sinus was absent. In view of this finding, together with the fact that structural brain abnormalities in KS are more frequent than in other congenital syndromes with multiple malformations, we propose that MRI be used in the diagnostic work-up of all patients with KS.

Computational haemodynamics in stenotic internal jugular veins.  

Science.gov (United States)

An association of stenotic internal jugular veins (IJVs) to anomalous cerebral venous hemodynamics and Multiple Sclerosis has been recently hypothesized. In this work, we set up a computational framework to assess the relevance of IJV stenoses through numerical simulation, combining medical imaging, patient-specific data and a mathematical model for venous occlusions. Coupling a three-dimensional description of blood flow in IJVs with a reduced one-dimensional model for major intracranial veins, we are able to model different anatomical configurations, an aspect of importance to understand the impact of IJV stenosis in intracranial venous haemodynamics. We investigate several stenotic configurations in a physiologic patient-specific regime, quantifying the effect of the stenosis in terms of venous pressure increase and wall shear stress patterns. Simulation results are in qualitative agreement with reported pressure anomalies in pathological cases. Moreover, they demonstrate the potential of the proposed multiscale framework for individual-based studies and computer-aided diagnosis. PMID:24671429

Computed tomographic evaluation of the portal vein in the hepatomas  

International Nuclear Information System (INIS)

Computed tomography and pornographic findings of 63 patients with hepatoma, undergone hepatic angiography and superior mesenteric pornography for evaluation of tumor and thrombosis of portal vein and determination of indication of transcatheter arterial embolization for palliative treatment of hepatoma from April, 85 to June, 86 in Hanyang university hospital, were reviewed. The results were as follows: 1. In 36 cases, portal vein thrombosis was detected during photography. Nineteen of 37 cases which revealed localized hepatoma in the right lobe of the liver showed portal vein thrombosis; 9 of 11 cases of the left lobe; 8 of 14 cases which were involved in entire liver revealed thrombosis. One case localized in the caudate lobe showed no evidence of invasion to portal vein. 2. Twenty-four of 34 cases with diffuse infiltrative hepatoma revealed portal vein thrombosis and the incidence of portal vein thrombosis in this type were higher than in the cases of the nodular type. 3. The portal vein thrombosis appeared as filling defects of low density in the lumen of the portal veins in CT and they did not reveal contrast enhancement. 4. CT revealed well the evidence of obstructions in the cases of portal vein thrombosis and the findings were well-corresponded to the findings of the superior mesenteric photography. 5. Five of the cases of the portal vein thrombosis were missed in the CT and the causes were considered as due to partial volume effect of enhanced portal vein wit volume effect of enhanced portal vein with partial occlusion or arterioportal shunts. 6. Six of 13 cases with occlusion of main portal vein showed cavernous transformation and they were noted as multiple small enhanced vascularities around the porta hepatis in the CT. According to the results, we conclude that CT is a useful modality to detect the changes of the portal veins in the patients of the hepatoma.

Portal vein aneurysm: a rare occurrence.  

Science.gov (United States)

Portal vein aneurysms (PVA) are a rare vascular anomaly of the portal system, representing fewer than 3% of all venous aneurysms, with only 150 known cases since first reported in l956 by Barzilai and Kleckner. PVA can be divided into 2 categories: extrahepatic and intrahepatic with acquired and congenital etiologies. Bimodal treatment includes medical and surgical approaches. With increased use of noninvasive radiological imaging, PVA will be increasingly recognized in the practice of vascular surgery. PMID:22062791

Transcutaneous laser treatment of leg veins.  

Science.gov (United States)

Leg telangiectasias and reticular veins are a common complaint affecting more than 80% of the population to some extent. To date, the gold standard remains sclerotherapy for most patients. However, there may be some specific situations, where sclerotherapy is contraindicated such as needle phobia, allergy to certain sclerosing agents, and the presence of vessels smaller than the diameter of a 30-gauge needle (including telangiectatic matting). In these cases, transcutaneous laser therapy is a valuable alternative. Currently, different laser modalities have been proposed for the management of leg veins. The aim of this article is to present an overview of the basic principles of transcutaneous laser therapy of leg veins and to review the existing literature on this subject, including the most recent developments. The 532-nm potassium titanyl phosphate (KTP) laser, the 585-600-nm pulsed dye laser, the 755-nm alexandrite laser, various 800-983-nm diode lasers, and the 1,064-nm neodymium yttrium-aluminum-garnet (Nd:YAG) laser and various intense pulsed light sources have been investigated for this indication. The KTP and pulsed dye laser are an effective treatment option for small vessels (pulse sequence or a dual-wavelength modality, inducing methemoglobin formation and enhancing the optical absorption properties of the target structure, (2) pulse stacking and multiple pass laser treatment, (3) combination of laser therapy with sclerotherapy or radiofrequency, and (4) indocyanin green enhanced laser therapy. Future studies will have to confirm the role of these developments in the treatment of leg veins. The literature still lacks double-blind controlled clinical trials comparing the different laser modalities with each other and with sclerotherapy. Such trials should be the focus of future research.

Angiographic investigation of the male gonadal vein  

International Nuclear Information System (INIS)

Retrograde angiography of the gonadal vein was carried out in 110 cases. Because of valve-insufficience the left vena spermatica interna filled spontaneously from the vena renalis in the majority (88%) of the cases. In the cases of well functioning valves superselective angiography was carried out. The examination is advised in cases of the following syndromes: varicokele, abdominal tumours, determination of the place of non-palpable testes, Klinefelter syndrome. (L.E.)

A complicated case of deep vein thrombosis  

Directory of Open Access Journals (Sweden)

Full Text Available We report a case of a patient with deep vein thrombosis (DVT and pulmonary thromboembolism (PTE associated to portal vein thrombosis (PVT, complicated by hospital-acquired pneumonia (HAP. The pathogenesis of DVT is multifactorial; among risk factors we can list: transitory situations (surgical interventions, infectious diseases with fever, traumas, acquired conditions (neoplasms, antiphospholipid syndrome or genetically determined situations (thrombophilia. PVT of the sovrahepatic veins is responsible for 5-10% of portal hypertension cases in adults and can be associated to local or systemic infections. PVT is present in 10% of patients with cirrhosis and often associated to cancers. It can also complicate a surgery abdominal intervention. HAP is defined as pneumonia that appears for the first time within 48 h of hospital admission. In Internal Medicine Departments the incidence is 7-10 cases/1.000 of hospital admissions, with an important impact in terms of both mortality and morbility. An early diagnosis, together with a correct identification of microbiologic agents in cause, allows a suitable antibiotic therapy with consequent improvement of clinical prognosis and a meaningful reduction of mortality. Main risk factors are: age, hospital and department. An important variable to be considered is the onset of pneumonia. The later is the onset of HAP (5 or more days from the admission to hospital, the more often is associated to multidrug resistant (MRD microorganisms, poorly responsive to antibiotic.

Retrohepatic vein injuries: experience with 20 cases.  

Science.gov (United States)

The mortality for injury of the retrohepatic veins is reported to vary from 50 to 100%. The use of hepatic bypass techniques, introduced in the 1960's, has not significantly decreased this mortality. We reviewed our experience with liver injuries over a 5-year period from 1982 to 1987 to determine our results with these particular injuries. Twenty patients had retrohepatic vein injuries. There were 11 patients with penetrating trauma and nine with blunt trauma. A total of 15 patients died, for a mortality rate of 75%. Fourteen patients died intraoperatively from exsanguination and one postoperatively from sepsis. A shunt was used in an attempt to bypass the injury in ten patients, with nine deaths. In the ten remaining patients who were not shunted, there were six deaths. Thus, in ten shunted patients the mortality was 90% and in ten non-shunted patients, 60%. Our review supports other studies reporting a lower mortality by direct exposure and repair of retrohepatic vein injuries. Although total vascular occlusion of the liver may not be well tolerated in hypotensive patients, rapid application of the above approach resulted in better patient survival than the use of shunts.

Finger Vein Recognition and Authentication System  

Directory of Open Access Journals (Sweden)

Full Text Available The protection for private information has steadily increased with the demand that the authentication has to be done in a highly secured method it is also simple and convenient. With this consideration and requirements for the emerging devices has to been done by the human physiological and biometric structures and behavior. One such biometrical identity is used in this paper is the finger vein. This is used as a biometric identity and authenticated also is experimented. The paper reveals about the high security system in our society to protect the personal information that is being theft. The main objective of this work is to implement a low cost budget system for protection purposes. This system is very simple and convenient not so complex like other biometric identification systems Finger print, palm size, hand shape, face recognition, iris identification and so on. Based on the application the component requirements can be increased or decreased which will constantly reflect on the cost of implementation of this project. Here the finger vein recognition system is implemented using MATLAB which is highly helpful in image processing applications. In this the real time finger is captured on and the image is processed using this software before the image is used. A novel finger vein algorithm is equipped in this system.

Quantitative modeling of quartz vein sealing  

Science.gov (United States)

Mineral precipitation significantly effects many aspects of fluid-rock interaction across all length scales, as the dynamical change of permeability, of mechanical interaction and redistribution of dissolved material. The hydrothermal growth of quartz establishes one of the most important mineralization processes in fractures. Tectonically caused fracturing, deformation and fluid transport leaves clear detectable traces in the microstructure of the mineralized veins. As these patterns give hints on the deformation history and the fluid pathways through former fracture networks, accurate spatio-temporal modeling of vein mineralization is of special interest, and the objective of this study. Due to the intricate polycrystalline geometries involved, the underlying physical processes like diffusion, advection and crystal growth have to be captured at the grain scale. To this end, we adapt a thermodynamically consistent phase-field model (PFM), which combines a kinetic growth law and mass transport equations with irreversible thermodynamics of interfaces and bulk phases. Each grain in the simulation domain is captured by a phase field with individual orientation given by three Euler angles. The model evolves in discrete time steps using a finite difference algorithm on a regular grid, optimized for large grain assemblies. The underlying processes are highly nonlinear, and for geological samples, boundary conditions as well as many of the physical parameters are not precisely known. One motivation in this study is to validate the adequately parameterized model vs. hydrothermal experiments under defined (p,T,c) conditions. Different from former approaches in vein growth simulation, the PFM is configured using thermodynamic data from established geochemical models. Previously conducted batch flow experiments of hydrothermal quartz growth were analyzed with electron backscatter diffraction (EBSD) and used to calibrate the unknown kinetic anisotropy parameters. In the simulations, we study the sealing of syntaxial veins of 300 microns aperture by epitaxial overgrowth of preexisting grains from the rock surface. Results from 3D simulations conducted in the limit of low Damköhler numbers explain the observed transition regime in competitive crystal growth for blocky-elongate veins. The initial formation of quartz crystal bridges, especially pronounced in the regime of low supersaturation, is observed. The morphological evolution of micro-ensembles of grain neighbourhoods from the rock sample compares well to that of the simulations. To juxtapose larger polycrystal domains, the variation of grain number, texture and porosity as function of scaled distance from the initial wall is calculated. Velocity profiles from solutions of the isothermal incompressible Navier-Stokes equation are used to record permeability evolution and to evaluate deviations from the cubic law. Both, the geometry of the microstructure and the permeability of the flow pathway, are used as upscaling parameters for larger scale (fracture scale) simulations.

Multiplex real-time PCR and culture methods for detection of Shiga toxin-producing Escherichia coli and Salmonella Thompson in strawberries, a lettuce mix and basil.  

Science.gov (United States)

An appropriate approach of high throughput multi-screening was verified for Shiga toxin-producing Escherichia coli (STEC) and Salmonella spp. in strawberries, lettuce and basil. Sample replicates were inoculated with STEC O157 or O26 and Salmonella Thompson (ca. 10-70, 100-700 and 1000-7000cfu/25g) and analysed after 1 and 5days of storage (strawberries and lettuce at 7°C and basil at 10°C). After 18-24h of enrichment at 37°C in buffered peptone water, detection was performed using the GeneDisc multiplex PCR (stx1, stx2, eae and iroB genes) and selective culture media for isolation of STEC (with immunomagnetic separation (IMS)) and Salmonella spp. in parallel. After 1day, the pathogenic strains were recovered from all samples for all inoculum levels, whereas reduced detection rates of STEC O157 and S. Thompson were observed after 5days of storage in case of strawberries, in particular for the lowest inoculums level, suggesting superior survival potential for STEC O26. Overall, this study indicates the ability of PCR based screening methods for reproducible multi-detection of low numbers (10-70cfu/25g) of STEC and Salmonella in this type of foods. However, for the basil samples, PCR needed twofold dilution of the DNA extract to overcome inhibition. It was noted that on several occasions growth of competitive microbiota obstructed finding presumptive colonies on the selective agar media, whereas the use of an additional agar medium such as CHROMagar STEC (without IMS) improved recovery rate of STEC.

Carcinoma of the breast presenting as deep vein thrombosis of the axillary vein  

Science.gov (United States)

Background: Breast cancer is the most common type of malignancy in the female population, rarely is reported by thromboembolic events during the course of the disease. In this case, we present a rare case of breast cancer presenting as deep vein thrombosis of the axillary vein. Case Presentation: A 40-year- old female was admitted due to pain and swelling of her right arm and forearm of two months’ duration. The right arm was grossly edematous with pitting edema. Breast examination showed non-tender fixed nodules in the right outer quadrant of the right breast. Doppler ultrasonography showed right axillary vein thrombosis. The pathologic examination of the nodules confirmed infiltrating ductal adenocarcinoma. Conclusion: This case highlights the procoagulant state of malignancies and it is important to remember that though rare, breast malignancies can present as deep venous thrombosis. This case also highlights the early and aggressive evaluation of any breast discharge to rule out carcinoma of the breast. PMID:24294476

Abdominal thromboses of splanchnic, renal and ovarian veins.  

Science.gov (United States)

Thromboses of abdominal veins outside the iliac-caval axis are rare but clinically relevant. Early deaths after splanchnic vein thrombosis occur in 5-30% of cases. Sequelae can be liver failure or bowel infarction after splanchnic vein thrombosis, renal insufficiency after renal vein thrombosis, ovarian infarction after ovarian vein thrombosis. Local cancer or infections are rare in Budd-Chiari syndrome, and common for other sites. Inherited thrombophilia is detected in 30-50% of patients. Myeloproliferative neoplasms are the main cause of splanchnic vein thrombosis: 20-50% of patients have an overt myeloproliferative neoplasm and/or carry the molecular marker JAK2 V617F. Renal vein thrombosis is closely related to nephrotic syndrome; finally, ovarian vein thrombosis can complicate puerperium. Heparin is used for acute treatment, sometimes in conjunction with systemic or local thrombolysis. Vitamin K-antagonists are recommended for 3-6 months, and long-term in patients with Budd-Chiari syndrome, unprovoked splanchnic vein thrombosis, or renal vein thrombosis with a permanent prothrombotic state such as nephrotic syndrome.

A vein display system based on three-dimensional reconstruction  

Science.gov (United States)

Venipuncture is the most common way of all invasive medical procedures. A vein display system can make vein access easier by capturing the vein information and projecting a visible vein image onto the skin, which is correctly aligned with the subject's vein. The existing systems achieve correct alignment by the design of coaxial structure. Such a structure causes complex optical and mechanical design and big physical dimensions inevitably. In this paper, we design a stereovision- based vein display system, which consists of a pair of cameras, a DLP projector and a near-infrared light source. We recover the three-dimensional venous structure from image pair acquired from two near-infrared cameras. Then the vein image from the viewpoint of projector is generated from the three-dimensional venous structure and projected exactly onto skin by the DLP projector. Since the stereo cameras get the depth information of vessels, the system can make sure the alignment of projected veins and the real veins without a coaxial structure. The experiment results prove that we propose a feasible solution for a portable and low-cost vein display device.

The clinical spectrum of renal vein thrombosis: acute and chronic.  

Science.gov (United States)

The present study is a prospective evaluation of 151 patients with the nephrotic syndrome in regard to the incidence of renal vein thrombosis, modes of clinical presentation, pathogenetic course and response to anticoagulant therapy. Of the 151 nephrotic patients studied, 33 had renal vein thrombosis and membranous nephropathy was present in 20. There were two modes of clinical presentation: (1) a sudden renal vein thrombosis was observed in the young patient with acute flank pain, marked costovertebral angle tenderness and macroscopic hematuria; a characteristic intravenous pyelogram, renal histologic changes and anticoagulant therapy were followed by marked improvement in renal function; (2) long-term renal vein thrombosis was observed in the older patients; they were asymptomatic and intravenous pyelograms disclosed no abnormalities; there were no suggestive renal histologic findings; the incidence of thromboembolic phenomena other than renal vein thrombosis was high, and there was mild progressive deterioration of renal function which was not altered by anticoagulant drugs; treated nephrotic patients with chronic renal vein thrombosis did not experience a new episode of thromboembolism whereas untreated nephrotic patients without renal vein thrombosis did. Finally, the sequence of nephrotic syndrome leading to renal vein thrombosis was clearly established showing the pathogenetic role of the nephrotic syndrome in renal vein thrombosis. Possible mechanisms in the pathogenesis of renal vein thrombosis are also discussed. PMID:7446547

Computed tomographic evaluation of the portal vein in the hepatomas  

Energy Technology Data Exchange (ETDEWEB)

Computed tomography and pornographic findings of 63 patients with hepatoma, undergone hepatic angiography and superior mesenteric pornography for evaluation of tumor and thrombosis of portal vein and determination of indication of transcatheter arterial embolization for palliative treatment of hepatoma from April, 85 to June, 86 in Hanyang university hospital, were reviewed. The results were as follows: 1. In 36 cases, portal vein thrombosis was detected during photography. Nineteen of 37 cases which revealed localized hepatoma in the right lobe of the liver showed portal vein thrombosis; 9 of 11 cases of the left lobe; 8 of 14 cases which were involved in entire liver revealed thrombosis. One case localized in the caudate lobe showed no evidence of invasion to portal vein. 2. Twenty-four of 34 cases with diffuse infiltrative hepatoma revealed portal vein thrombosis and the incidence of portal vein thrombosis in this type were higher than in the cases of the nodular type. 3. The portal vein thrombosis appeared as filling defects of low density in the lumen of the portal veins in CT and they did not reveal contrast enhancement. 4. CT revealed well the evidence of obstructions in the cases of portal vein thrombosis and the findings were well-corresponded to the findings of the superior mesenteric photography. 5. Five of the cases of the portal vein thrombosis were missed in the CT and the causes were considered as due to partial volume effect of enhanced portal vein with partial occlusion or arterioportal shunts. 6. Six of 13 cases with occlusion of main portal vein showed cavernous transformation and they were noted as multiple small enhanced vascularities around the porta hepatis in the CT. According to the results, we conclude that CT is a useful modality to detect the changes of the portal veins in the patients of the hepatoma.

Functional dissection of the cis-acting sequences of the Arabidopsis transposable element Tag1 reveals dissimilar subterminal sequence and minimal spacing requirements for transposition.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The Arabidopsis transposon Tag1 has an unusual subterminal structure containing four sets of dissimilar repeats: one set near the 5' end and three near the 3' end. To determine sequence requirements for efficient and regulated transposition, deletion derivatives of Tag1 were tested in Arabidopsis plants. These tests showed that a 98-bp 5' fragment containing the 22-bp inverted repeat and four copies of the AAACCX (X = C, A, G) 5' subterminal repeat is sufficient for transposition while a 52-b...

Phase equilibrium in systems with ionic liquids: An example for the downstream process of the Biphasic Acid Scavenging utilizing Ionic Liquids (BASIL) process. Part I: Experimental data  

International Nuclear Information System (INIS)

Highlights: ? Phase equilibrium for a downstream process in sustainable chemical technology. ? Biphasic Acid Scavenging Utilizing Ionic Liquids (BASIL) Process. ? SLE, LLE, and SLLE of (NaCl + water + 1-propanol + 1-MIM) and its ternary subsystems. ? Experimental phase equilibrium data at temperatures between 298 K and 333 K. - Abstract: Experimental results are presented for the (liquid + liquid), (solid + liquid) and (solid + liquid + liquid) equilibria occurring in the downstream process of a typical example for the Biphasic Acid Scavenging Utilizing Ionic Liquids (BASIL)-processes. In a BASIL process an organic base is used to catalyze a chemical reaction and, at the same time, to scavenge an acid that is an undesired side product of that reaction. The particular example of a BASIL process treated here is the reaction of 1-butanol and acetylchloride to butylacetate and hydrochloric acid, where the acid is scavenged by the organic base 1-methyl imidazole (1-MIM) resulting in the ionic liquid 1-methyl imidazolium chloride. The reaction results in a two-phase system as butylacetate and the ionic liquid reveal a large liquid–liquid miscibility gap. The organic base has to be recovered. This is commonly achieved by treating the ionic liquid–rich liquid phase with an aqueous solution of sodium hydroxide (i.e., converting the ionic liquid to the organic base) and extracting the organic base by an appropriate organic solvent (e.g., 1-propanol). The work presen, 1-propanol). The work presented here deals in experimental work with the (liquid + liquid), (solid + liquid) and (solid + liquid + liquid) phase equilibria that are encountered in such extraction processes. Experimental results are reported for temperatures between about 298 K and 333 K: for the solubility of NaCl in several solvents (1-propanol, 1-MIM), (water + 1-MIM), (1-propanol + 1-MIM), (water + 1-propanol), and (water + 1-propanol + 1-MIM) and for the (liquid + liquid) equilibrium as well as for the (solid + liquid + liquid) equilibrium of the ternary system (NaCl + water + 1-propanol) and of the quaternary system (NaCl + water + 1-propanol + 1-MIM).

Corrected transposition of the great arteries with several associated anomalies in a 68-year-old patient  

Directory of Open Access Journals (Sweden)

Full Text Available Few patients with corrected transposition of the great arteries survive past 50 years of age because of the association with congenital defects, development of total atrioventricular block, and right ventricular dysfunction. We report the case of a male patient with dextrocardia in situs solitus and corrected transposition of the great arteries associated with a wide atrial septal defect and severe pulmonary valvar and subvalvar stenoses. The patient also developed a large aneurysm on the pulmonary artery, total atrioventricular block diagnosed 8 years earlier, symptoms of dysfunction of the systemic ventricle in the previous 2 years, insufficiency of the left atrioventricular valve, and aortic regurgitation. Despite all these associated anomalies, the patient developed class III cardiac decompensation only at the age of 68 years, which makes this case a rarity. The patient was clinically treated, and was discharged from the hospital in good condition.

We report the case of a male patient with dextrocardia in situs solitus and [...] corrected transposition of the great arteries associated with a wide atrial septal defect and severe pulmonary valvar and subvalvar stenoses. The patient also developed a large aneurysm on the pulmonary artery, total atrioventricular block diagnosed 8 years earlier, symptoms of dysfunction of the systemic ventricle in the previous 2 years, insufficiency of the left atrioventricular valve, and aortic regurgitation. Despite all these associated anomalies, the patient developed class III cardiac decompensation only at the age of 68 years, which makes this case a rarity. The patient was clinically treated, and was discharged from the hospital in good condition.

The compression syndrome of the left renal vein  

International Nuclear Information System (INIS)

Severe compression of the left renal vein produces a pressure gradient between it and the inferior vena cava and results in changes in haemodynamics. The cause of the narrowing is usually the aorta, less commonly the superior mesenteric artery. Compression of the left renal vein may be responsible for a number of abnormalities such as primary varicoceles, primary varices of the ovarian, renal, pelvic and ureteric veins on the left, the more frequent occurrence of unilateral renal vein thrombosis on the left and the development of renovascular hypertension. One hundred and twenty-three selective phlebograms of the left renal vein and CT examinations of this structure in a further 87 patients acting as a control group were carried out. The significance of compression of the left renal vein as an aetiological factor in the development of the above mentioned abnormalities is discussed. (orig.)

Portal vein arterialization technique for liver transplantation patients  

Science.gov (United States)

Liver transplantations were performed on two patients with hepatic failure caused by liver cirrhosis. Hard obsolete thrombi and portal venous sclerosis were observed in the major portal veins of both patients. The arteria colica media of one recipient and the portal vein of the donor were anastomosed end-to-end. The hepatic artery of the first donor was anastomosed end-to end with the gastroduodenal artery of the first recipient; meanwhile, the portal vein of the second donor was simultaneously anastomosed end- to-end with the common hepatic artery of the second recipient. The blood flow of the portal vein, the perfusion of the donor liver and liver function were satisfactory after surgery. Portal vein arterialization might be an effective treatment for patients whose portal vein reconstruction was difficult. PMID:25232274

Anticardiolipin antibodies in children with portal vein thrombosis  

Directory of Open Access Journals (Sweden)

Full Text Available Aim: The aim of this study was to evaluate the frequency of anticardiolipin antibodies in children with portal vein thrombosis and whether anticardiolipin antibodies have effect on thrombosis in the portal vein.Material and Method: IgG and IgM anticardiolipin levels were measured in 20 patients with portal vein thrombosis and in 20 healthy controls using an ELISA method. Results: IgG anticardiolipin levels (GPL unit were found as 13.9±4.8 in the portal vein thrombosis patients and 4.4±1.9 in the control group (p0.05. In seven (35% portal vein thrombosis patients and in one (5% in the control group anticardiolipin IgG (p0.05 levels were high (>10 GPL and MPL unit. Conclusions: IgG anticardiolipin antibodies are significantly associated with portal vein thrombosis in children. (Turk Arch Ped 2009; 44: 124-6
