Saphenous Vein or Basilic Vein Transposition in Hemodialysis Patients?  

Directory of Open Access Journals (Sweden)

Full Text Available OBJECTIVE: Secondary arteriovenous fistula (AVF management with saphenous vein (SV graft and basilic vein transposition (BVT in HD-dependent patients are good alternatives. A concurrent series of patients was reviewed to evaluate the patency and complication rates after AVF formation. MATERIAL and METHODS: From January 2006 to January 2010, 40 secondary HD access procedures were performed in 40 consecutive patients. All access procedures were planned on the basis of preoperative duplex ultrasonography (USG scans of arm and forearm veins. Functional patency was defined as the ability to cannulate the patient for HD successfully. Primary and secondary cumulative functional patency of SV grafts and BVT's were determined with the Kaplan Meier test, differences were analyzed with Log Rank test, and differences in revision rates including thrombolysis thrombectomies and operative revisions were analyzed with the Z test and the Fisher exact T test. RESULTS: Mean follow up was 48 months (range 43-54 months. Risk factors were similar between the two groups. SV group and BVT group had similar patency ratings. The HD access complication rates were higher in the SV group. CONCLUSION: Our data strongly support the notion that the BVT must always be considered before an SV graft as long as the patient is a candidate for an upper arm secondary AVF creation based on anatomical criteria

Transposição da Veia Basílica: um contributo para a melhoria da técnica cirúrgica / Basilic Vein Transposition: improvement of the surgical technique  

Scientific Electronic Library Online (English)

Full Text Available Introdução: O aumento crescente da população em hemodiálise tem implicado o recurso a acessos vasculares de maior complexidade técnica. A introdução de modificações na técnica cirúrgica da transposição da veia basílica (TVB) pretende agilizar o procedimento e diminuir a sua morbilidade. Métodos: Aná [...] lise prospectiva das TVB efectuadas no CHP-HSA entre Setembro de 2005 e Setembro de 2009. Resultados: Efectuaram-se 74 TVB em 74 doentes, os quais tinham, em média, 2 acessos autólogos prévios. A TVB foi o primeiro acesso em 20,3% dos doentes. O intervalo médio de seguimento foi de 14,5 meses. Ocorreram 2 falências nos primeiros 30 dias. A taxa de patência secundária aos 3, 12 e 24 meses foi de 95,7%, 85,1% e 62,2%, respectivamente. A Diabetes associou-se a pior taxa de patência (p=0,018). A taxa de complicações perioperatórias foi de 28,4%, sendo a infecção a mais frequente (n=6, 8,1% do total de TVB). A trombose foi a principal causa de falência, tendo ocorrido em 24,3% de todas as TVB. Conclusões: Reconhece-se a superioridade do acesso autólogo, como a melhor opção de acesso vascular para hemodiálise. A TVB é subutilizada, devido às exigências técnicas e necessidades logísticas. Melhoramos a técnica cirúrgica e de tunelização, ao reduzir o tamanho das incisões e o tempo cirúrgico. Os nossos resultados revelaram uma boa patência a longo prazo, pelo que consideramos que deve ser mais utilizada. Abstract in english Introduction: The expanding haemodialysis population has lead to increased requirement for more complex vascular accesses. Modifications introduced in basilic vein transposition technique are intended to streamline the procedure and reduce its morbidity. Methods: All patients who underwent BVT from [...] September 2005 to September 2009 in CHP-HSA were prospectively reviewed. Results: Seventy-four BVT were performed in 74 patients. Patients had a mean of 2.0 previous access attempts. BVT was the first access in 20.3% of the patients. Median follow-up was 14.5 months. There were two primary failures. Secondary patency rates were 95.7%, 85.1% and 62.2% at 3, 12 and 24 months, respectively. Diabetes was associated with poor patency. Perioperative complication rate was 28.4%, with infection being the most frequent (n=6, 8.1% of all TVB). Thrombosis was the main cause of failure, occurring in 24.3% of all TVB. Conclusion: Autologous access superiority is well established. BVT is an underused technique due to its surgical expertise needs and logistic demands. We improved the surgical technique and the tunneling technique, reducing the size of the incisions and the time of operation. Our results showed a good secondary patency rate and, in the authors view, this technique should be more widely used.

Distal revascularization and interval ligation procedure for radial-basilic forearm transposition arteriovenous fistula.  

Science.gov (United States)

The distal revascularization and interval ligation procedure is commonly performed for steal syndrome in upper arm arteriovenous accesses and is rarely performed in the forearm. We present a case of distal revascularization and interval ligation procedure performed for a 60-year-old male who presented with a 3-month history of a nonhealing ulcer of his left middle finger as a result of ischemic steal syndrome 4 years after having a left radial-basilic forearm transposition arteriovenous fistula.

Left renal vein transposition is effective for posterior nutcracker syndrome.  

Science.gov (United States)

An 8-year-old girl was enrolled in hospital with intermittent gross hematuria in a period of 3 years. Bloody efflux from the left ureteral orifice was diagnosed in this patient with urethrocystoscopy. A retroaortic left renal vein appeared to be compressed by the aorta as detected by computerized tomography. The left renal vein was compressed between the aorta and the spine. A groove in the anterior surface of the left renal vein was detected. A transposition surgery of the left renal vein to a site in front of the aorta was performed for the patient. The patient was discharged after recovery and the hematuria symptom was not found during the 15-month follow-up investigation. PMID:25664135

Two-stage brachial-basilic transposition fistula provides superior patency rates for dialysis access in a safety-net population  

Science.gov (United States)

Background Guidelines of the National Kidney Foundation recommending aggressive pursuit of autogenous fistulae for dialysis access in lieu of prosthetic arteriovenous grafts have stimulated a renewed interest in transposed brachial-basilic fistulae as an alternative technique for upper arm access in patients who may not be candidates for a lower arm radial-cephalic or forearm brachial-cephalic fistula. We hypothesized that in our safety-net population, where radial-cephalic and brachial-cephalic often are not possible, brachial-basilic would provide patency rates superior to arteriovenous grafts and equivalent to radial-cephalic and brachial-cephalic fistulae. Methods We analyzed retrospectively our most recent 2.5-year experience with dialysis access procedures at our metropolitan safety-net hospital. Procedures were grouped as follows: radial-cephalic, brachial-cephalic, brachial-basilic, and arteriovenous grafts. The access outcomes measured were primary failure, time to use, need for intervention, and primary as well as secondary patency. Differences in age, sex, race, renal function (Modification of Diet in Renal Disease), baseline diagnoses (diabetes mellitus, hypertension, coronary artery disease, and peripheral vascular disease), as well as the number of previous accesses, were adjusted in the analysis. Logistic regression was used to identify independent predictors of primary failure, and Kaplan-Meier plots assessed differences in primary patency rates. A log of the time variables was used to approximate normal distribution. Results In all, 193 patients were included in this study as follows: radial-cephalic, 75 (39%) patients; brachial-cephalic, 35 (18%) patients; brachial-basilic, 33 (17%) patients; and arteriovenous grafts, 50 (26%) patients. Primary patency means differed marginally between groups (P = .08), and when grafts were excluded from the analysis, no difference was found between primary patency in all autogenous fistula techniques (P = .88). Kaplan-Meier plots showed that when analyzing the first 35 weeks, a significantly lower primary patency among graft recipients early after the procedure was noted, and a higher performance of BB after 20 weeks was noted (log-rank P = .05,Wilcoxon P = .004). Furthermore, secondary patency did not vary significantly between groups (P = .62). Radial-cephalic were more likely to fail primarily when compared with the other access groups (P = .03), and in a univariate analysis, underlying hypertension was associated with a lower risk of primary failure (P = .01) compared with other diagnoses. A logistic regression stepwise selection showed that the underlying diagnoses of peripheral vascular disease, diabetes mellitus, or coronary artery disease were associated with a greater risk of primary failure compared with those with HTN (P = .001; odds ratio, 4.05; 95%confidence interval, 1.71–9.59), as well as the presence of a previously failed access (P = .04; odds ratio, 2.39; 95% confidence interval, 1.08–5.67). Conclusion In a safety-net population, our results suggest that 2-stage brachial-basilic transposition fistulae provide patency rates equivalent to brachial-cephalic and radial-cephalic fistulae and superior to grafts. Although 2 procedures are required, brachial-basilic fistulae provide a reliable access and should be considered the next choice when radial-cephalic and/or brachial-cephalic are not possible.

Balloon atrial septostomy through internal jugular vein in a 45-day-old child with transposition of great arteries  

Directory of Open Access Journals (Sweden)

Full Text Available Balloon atrial septostomy is a common palliative procedure in D-transposition of great arteries. It is technically easy before 2-3 weeks of age when the septum primum is thin. Femoral vein or umbilical vein, when available, is the common access used for this procedure. In situations when these accesses are not available or in case of inferior vena cava interruption, trans-hepatic access is used. Internal jugular vein (IJV access is not used as it is difficult to enter the left atrium through this route. We describe a case of successful Balloon atrial septostomy done through IJV in a 45-day-old child with emphasis on the technique, hardware and precautions necessary during the procedure.

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.

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.

Transposition of the great arteries  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Transposition of the great arteries (TGA, also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA discordance. The incidence is estimated at 1 in 3,500–5,000 live births, with a male-to-female ratio 1.5 to 3.2:1. In 50% of cases, the VA discordance is an isolated finding. In 10% of cases, TGA is associated with noncardiac malformations. The association with other cardiac malformations such as ventricular septal defect (VSD and left ventricular outflow tract obstruction is frequent and dictates timing and clinical presentation, which consists of cyanosis with or without congestive heart failure. The onset and severity depend on anatomical and functional variants that influence the degree of mixing between the two circulations. If no obstructive lesions are present and there is a large VSD, cyanosis may go undetected and only be perceived during episodes of crying or agitation. In these cases, signs of congestive heart failure prevail. The exact aetiology remains unknown. Some associated risk factors (gestational diabetes mellitus, maternal exposure to rodenticides and herbicides, maternal use of antiepileptic drugs have been postulated. Mutations in growth differentiation factor-1 gene, the thyroid hormone receptor-associated protein-2 gene and the gene encoding the cryptic protein have been shown implicated in discordant VA connections, but they explain only a small minority of TGA cases. The diagnosis is confirmed by echocardiography, which also provides the morphological details required for future surgical management. Prenatal diagnosis by foetal echocardiography is possible and desirable, as it may improve the early neonatal management and reduce morbidity and mortality. Differential diagnosis includes other causes of central neonatal cyanosis. Palliative treatment with prostaglandin E1 and balloon atrial septostomy are usually required soon after birth. Surgical correction is performed at a later stage. Usually, the Jatene arterial switch operation is the procedure of choice. Whenever this operation is not feasible, adequate alternative surgical approach should be implemented. With the advent of newer and improved surgical techniques and post operative intensive care, the long-term survival is approximately 90% at 15 years of age. However, the exercise performance, cognitive function and quality of life may be impaired.

Gastric Transposition for Esophageal Replacement in Children  

Science.gov (United States)

Objective To evaluate the authors’ experience with gastric transposition as a method of esophageal replacement in children with congenital or acquired abnormalities of the esophagus. Summary Background Data Esophageal replacement in children is almost always done for benign disease and thus requires a conduit that will last more than 70 years. The organ most commonly used in the past has been colon; however, most series have been fraught with major complications and conduit loss. For these reasons, in 1985 the authors switched from using colon interpositions to gastric transpositions for esophageal replacement in infants and children. Methods The authors retrospectively reviewed the records of 41 patients with the diagnoses of esophageal atresia (n = 26), corrosive injury (n = 8), leiomyomatosis (n = 5), and refractory gastroesophageal reflux (n = 2) who underwent gastric transposition for esophageal replacement. Results Mean ± SE age at the time of gastric transposition was 3.3 ± 0.6 years. All but two transpositions were performed through the posterior mediastinum without mortality or loss of the gastric conduit despite previous surgery on the gastric fundus in 8 (20%), previous esophageal operations in 15 (37%), and previous esophageal perforations in 6 (15%) patients. Complications included esophagogastric anastomotic leak (n = 15, 36%), which uniformly resolved without intervention; stricture formation (n = 20, 49%), all of which no longer require dilation; and feeding intolerance necessitating jejunal feeding (n = 8, 20%) due to delayed gastric emptying (n = 3), feeding aversion related to the underlying anomaly (n = 1), or severe neurological impairment (n = 4). No redo anastomoses were required. Conclusions Gastric transposition reestablishes effective gastrointestinal continuity with few complications. Oral feeding and appropriate weight gain are achieved in most children. Therefore, gastric transposition is an appropriate alternative for esophageal replacement in infants and children.

Preventive orthodontic management of tooth transposition.  

Science.gov (United States)

The contemporary orthodontics should highlight the periodical control of growth and dental development in order to intercept possible disorders in facial growth and tooth eruption. This may allow avoidance or simplification of corrective orthodontic treatment, making it faster and less aggressive. Tooth transposition, a genetically determined eruptive disturbance, presents a relatively low prevalence in the world population and primarily affects maxillary canines and premolars. This paper presents an option for interceptive treatment of bilateral transposition of maxillary canine and premolar diagnosed early in a young individual. Longitudinal follow-up of RME performed in adequate timing to redirect the eruption pathway of permanent maxillary canines is presented. PMID:25745710

Utilization of Basil Extract as a Radioprotector in Male Rats  

International Nuclear Information System (INIS)

Man is exposed to natural radiations from cosmic or terrestrial origins. Furthermore, it is well known that the gamma irradiation-induced biochemical alteration depends mostly on oxidative stress. Basil or sweet basil (Ocimum basilicum) is known to have numerous pharmacological activities. Therefore, the present study was carried out to investigate the radioprotective activity of basil in albino rats. The effect of basil aqueous extract (BAE) was evaluated on hepatic marker enzymes, sex hormones, lipid profile and antioxidant status. The results showed that - rays caused a significant increase in serum level of alanine and aspartate aminotransferase, alkaline phosphatase, gamma glutamyl transpeptidase (ALT, AST, ALP and GT), cholesterol (TC), triglyceride (TG), low and very low density lipoprotein cholesterol (LDL-C and VLDL-C) and thiobarbituric acid reactive substances (TBARS). A significant decrease in high density lipoprotein cholesterol (HDL-C), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) in serum was observed, compared with control group. Moreover, - rays induced a significant drop in the serum sex hormones levels testosterone (T), follicle stimulating hormone (FSH) and luteinizing hormone (LH). The BAE administered orally to rats has significantly modulated all the radiation-induced biochemical alterations. These findings showed that basil would exert a radioprotective properties.

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)

Upper limb vein anatomy before hemodialysis fistula creation: cross-sectional anatomy using MR venography  

International Nuclear Information System (INIS)

Preoperative imaging is indicated to discriminate patent, adequate superficial veins of the upper limbs undetectable by clinical inspection that could be anastomosed for the creation of a durable and functional hemodialysis fistula. The aim of this pictorial review is to provide a venous anatomic map of the upper limbs using MR venography (MRV) which could help surgeons before creation of hemodialysis access fistulas (AVF). At the level of the forearm, the antebrachial cephalic vein is the most commonly identified as patent. At the level of the elbow and distal arm, the cephalic vein is patent in 80% of normal subjects, and less often patent (23-26%) than basilic vein (33-38%) in patients. Overall, reading transaxial MR views can help for assessing upper limb vein anatomy before creation of a hemodialysis access fistula. (orig.)

Application of high Cu compost to Swiss chard and basil.  

Science.gov (United States)

A greenhouse container experiment was conducted to evaluate the effect of high Cu compost on basil and Swiss chard productivity, and the accumulation of As, Ca, Fe, Hg, K, Mg, Na, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, S and Se in growth medium and plant tissue. The Cu content of the compost was over 1200 mg/kg, much higher than Canadian standards for type B compost quality. The treatments consisted of control soil (0% compost), and 20, 40 and 60% (by volume) of high Cu compost added to soil. All compost application treatments (20, 40 and 60%) resulted in increased dry matter yields in Swiss chard and basil. Addition of high Cu compost influenced basil plant development. Plants from the 20 and 40% treatments had higher numbers of buds and flowers. There were no differences between the control and 60% compost treatments with respect to flower initiation. Addition of 20, 40 and 60% compost to the soil resulted in increased EXCH fractions of Cu, but not of Mn and Zn. Compost additions resulted in increase in the HNO(3) extractable, CARB, FeMnOX, and in OM fractions of Cu, Mn and Zn in soils. Compost application increased soil pH and EC, soil HNO(3) extractable Ca, K, Mg, P, Na, B and Pb, but did not alter soil HNO(3) extractable Cd, Co, Cr, Mo, Ni, Se. Increased rates of compost application decreased tissue Ca in basil, tissue Na in both plants, increased tissue K, Mg in both plants, but, did not alter tissue P, Co, Cr, Mo, Ni of either plants, and B in basil. Tissue As, Hg, Pb, and Se from all treatments were under the detection limits of VGA-AAS (for As, Hg, Se) and ICP (for Pb). Compost additions altered basil oil chemical composition. Copper in the essential oil of basil was below 0.25 mg/l. In conclusion, the addition of high rates of relatively immature high Cu compost may not always increase Cu concentration in plants and in plant oils. PMID:12526895

The transposition distance for phylogenetic trees  

CERN Document Server

The search for similarity and dissimilarity measures on phylogenetic trees has been motivated by the computation of consensus trees, the search by similarity in phylogenetic databases, and the assessment of clustering results in bioinformatics. The transposition distance for fully resolved phylogenetic trees is a recent addition to the extensive collection of available metrics for comparing phylogenetic trees. In this paper, we generalize the transposition distance from fully resolved to arbitrary phylogenetic trees, through a construction that involves an embedding of the set of phylogenetic trees with a fixed number of labeled leaves into a symmetric group and a generalization of Reidys-Stadler's involution metric for RNA contact structures. We also present simple linear-time algorithms for computing it.

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.

Resistance to essential oils affects survival of Salmonella enterica serovars in growing and harvested basil.  

Science.gov (United States)

The number of outbreaks of food-borne illness associated with consumption of fresh products has increased. A recent and noteworthy outbreak occurred in 2007. Basil contaminated with Salmonella enterica serovar Senftenberg was the source of this outbreak. Since basil produces high levels of antibacterial compounds the aim of this study was to investigate if the emerging outbreak reflects ecological changes that occurred as a result of development of resistance to ingredients of the basil oil. We irrigated basil plants with contaminated water containing two Salmonella serovars, Typhimurium and Senftenberg, and showed that Salmonella can survive on the basil plants for at least 100 days. S. Senftenberg counts in the phyllosphere were significantly higher than S. Typhimurium, moreover, S. Senftenberg was able to grow on stored harvested basil leaves. Susceptibility experiments demonstrated that S. Senftenberg is more resistant to basil oil and to its antimicrobial constituents: linalool, estragole and eugenol. This may indicate that S. Senftenberg had adapted to the basil environment by developing resistance to the basil oil. The emergence of resistant pathogens has a significant potential to change the ecology, and opens the way for pathogens to survive in new niches in the environment such as basil and other plants.

Survival of Salmonella on basil plants and in pesto.  

Science.gov (United States)

Leafy greens, including fresh herbs, have repeatedly been involved in outbreaks of foodborne disease. Although much effort has been put into studying leafy greens and products such as head lettuce and baby leaves, less is known about fresh leafy herbs, such as basil. The goal of this study was to investigate the survival of Salmonella on basil plants and in pesto. A mix of three Salmonella strains (Reading, Newport, and Typhimurium) was inoculated onto basil leaves and pesto and survived during the experimental period. Whereas the mix of Salmonella survived in pesto stored at 4°C for 4 days, Salmonella was recovered from inoculated leaves for up to 18 days at 20 to 22°C. Although the steady decline of Salmonella on leaves and in pesto suggests a lack of growth, it appears that pesto is a hostile environment for Salmonella because the rate of decline in pesto was faster (0.29 log CFU/g/day) than on leaves (0.11 log CFU/g/day). These findings suggest that the dilution of contaminated ingredients and the bactericidal effect of the pesto environment helped to further reduce the level of enteric organisms during storage, which may have applications for food safety.

Variations of the cubital superficial vein investigated by using the intravenous illuminator  

Science.gov (United States)

The purpose of this study was to report variations of the cubital superficial vein patterns in the Korean subjects, which was investigated by using venous illuminator, AccuVein. The 200 Korean subjects were randomly chosen from the patients and staff of the Keimyung University Dongsan Medical Center in Daegu, Korea. After excluding the inappropriate cases for detecting venous pattern, we collected 174 cases of right upper limbs and 179 cases of left upper limbs. The superficial veins of the cubital fossa were detected and classified into four types according to the presence of the median cubital vein (MCV) or median antebrachial vein. The type II, presenting the both cephalic and basilic vein connected by the MCV, was most common (177 upper limbs, 50.1%). Although the most common type in male and female was different as type I (108 upper limbs, 49.3%) and type II (75 upper limbs, 56.0%), respectively, statistical significance was not detected (P=0.241). The frequency of the each types between right and left upper limbs was also not different (P=0.973). Among 154 subjects who were observed the venous pattern in the both upper limbs, 76 subjects (49.3%) had the same venous pattern. Using AccuVein to investigate the venous pattern has an advantage of lager scale examination compared to the cadaver study. Our results might be helpful for medical practitioner to be aware of the variation of the superficial cubital superficial vein. PMID:25806123

Variations of the cubital superficial vein investigated by using the intravenous illuminator.  

Science.gov (United States)

The purpose of this study was to report variations of the cubital superficial vein patterns in the Korean subjects, which was investigated by using venous illuminator, AccuVein. The 200 Korean subjects were randomly chosen from the patients and staff of the Keimyung University Dongsan Medical Center in Daegu, Korea. After excluding the inappropriate cases for detecting venous pattern, we collected 174 cases of right upper limbs and 179 cases of left upper limbs. The superficial veins of the cubital fossa were detected and classified into four types according to the presence of the median cubital vein (MCV) or median antebrachial vein. The type II, presenting the both cephalic and basilic vein connected by the MCV, was most common (177 upper limbs, 50.1%).

Portal vein thrombosis.  

Science.gov (United States)

Portal vein thrombosis (PVT) is the blockage or narrowing of the portal vein by a thrombus. It is relatively rare and has been linked with the presence of an underlying liver disease or prothrombotic disorders. We present a case of a young male who presented with vague abdominal symptoms for approximately one week. Imaging revealed the presence of multiple nonocclusive thrombi involving the right portal vein, the splenic vein, and the left renal vein, as well as complete occlusion of the left portal vein and the superior mesenteric vein. We discuss pathogenesis, clinical presentation, and management of both acute and chronic thrombosis. The presence of PVT should be considered as a clue for prothrombotic disorders, liver disease, and other local and general factors that must be carefully investigated. It is hoped that this case report will help increase awareness of the complexity associated with portal vein thrombosis among the medical community. PMID:25802795

Pig transgenesis by Sleeping Beauty DNA transposition  

DEFF Research Database (Denmark)

Modelling of human disease in genetically engineered pigs provides unique possibilities in biomedical research and in studies of disease intervention. Establishment of methodologies that allow efficient gene insertion by non-viral gene carriers is an important step towards development of new disease models. In this report, we present transgenic pigs created by Sleeping Beauty DNA transposition in primary porcine fibroblasts in combination with somatic cell nuclear transfer by handmade cloning. Göttingen minipigs expressing green fluorescent protein are produced by transgenesis with DNA transposon vectors carrying the transgene driven by the human ubiquitin C promoter. These animals carry multiple copies (from 8 to 13) of the transgene and show systemic transgene expression. Transgene-expressing pigs carry both transposase-catalyzed insertions and at least one copy of randomly inserted plasmid DNA. Our findings illustrate critical issues related to DNA transposon-directed transgenesis, including coincidental plasmid insertion and relatively low Sleeping Beauty transposition activity in porcine fibroblasts, but also provide a platform for future development of porcine disease models using the Sleeping Beauty gene insertion technology.

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.

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.

Anatomical study of distribution of valves of the cutaneous veins of adult's limbs.  

Science.gov (United States)

Since the cutaneous veins of the four limbs have been used as autogenous grafts in the treatment of cardiovascular disorders, knowledge of distribution of the valves is increasingly required depending upon the use. In the gross anatomical study of distribution of valves of the trunci venae, there has been argument about locational relationships between the venous roots and the valves in the vicinity of the roots and the inter-valvular distance. However, there have been only few reports discussing detailed information about valves of the cutaneous veins of the four limbs. The authors observed patterns of distribution of the cutaneous venous valves of the four limbs of cadavers prepared for practice in anatomy. The following parts were excised from each cadaver: the cephalic, basilic, and the great saphenous veins, which originate from the acral venous network and flow into the proximal deep veins, and the venous roots communicating with these veins. An incision was made on each excised vein in the direction of the long axis under observation with a stereoscopic microscope, and the inter-valvular distance and the distance between the valve and the orifice of venous root in the vicinity of the valve were measured. The inter-valvular distance varied with type of the truncus venae, and it varied according to area even in the same truncus venae. PMID:12597133

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.

Rapid Staining Method to Detect and Identify Downy Mildew (Peronospora belbahrii in Basil  

Directory of Open Access Journals (Sweden)

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

CHEMICAL COMPOSITION AND ANTIMICROBIAL PROPERTIES OF DIFFERENT BASIL OILS  

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Efficient sleeping beauty DNA transposition from DNA minicircles  

DEFF Research Database (Denmark)

DNA transposon-based vectors have emerged as new potential delivery tools in therapeutic gene transfer. Such vectors are now showing promise in hematopoietic stem cells and primary human T cells, and clinical trials with transposon-engineered cells are on the way. However, the use of plasmid DNA as a carrier of the vector raises safety concerns due to the undesirable administration of bacterial sequences. To optimize vectors based on the Sleeping Beauty (SB) DNA transposon for clinical use, we examine here SB transposition from DNA minicircles (MCs) devoid of the bacterial plasmid backbone. Potent DNA transposition, directed by the hyperactive SB100X transposase, is demonstrated from MC donors, and the stable transfection rate is significantly enhanced by expressing the SB100X transposase from MCs. The stable transfection rate is inversely related to the size of circular donor, suggesting that a MC-based SB transposition system benefits primarily from an increased cellular uptake and/or enhanced expression which can be observed with DNA MCs. DNA transposon and transposase MCs are easily produced, are favorable in size, do not carry irrelevant DNA, and are robust substrates for DNA transposition. In accordance, DNA MCs should become a standard source of DNA transposons not only in therapeutic settings but also in the daily use of the SB system.Molecular Therapy - Nucleic Acids (2013) 2, e74; doi:10.1038/mtna.2013.1; published online 26 February 2013.

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.

Adrenal vein catheterization  

International Nuclear Information System (INIS)

Twenty post-mortem specimens and 93 phlebographies (56 right side, 37 left side) from 44 patients were investigated with respect to the adrenal venous anatomy. At autopsy, the venous orifices displayed in the area of adrenal drainage were injected bilaterally to identify the adrenal vein(s), the surrounding channels and the presence of interconnections. The findings were correlated with those at clinical phlebography, and the different sources of error were elicited. These were mainly found on the right side. Some guidelines are suggested in the hope that these will contribute to eliminate misconceptions. (Auth.)

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.

In vitro Anti-Bacterial Activity of Sweet Basil Fractions Against Helicobacter pylori  

Directory of Open Access Journals (Sweden)

Full Text Available In tihis study, the effect of sweet basil fractions on growth of H. pylori was studied by filter paper Disc Diffusion Method (DDM on egg yolk emulsion agar. Aqueous fraction had no activity against nine tested clinical isolates. Methanol, n-hexane and butanol fractions showed in vitro anti Helicobacter pylori effects. There are no differences (p>0.05 among anti Helicobacter pylori activity of methanol, n-hexane and butanol fractions at concentration of 1 mg, but in lower concentrations, methanol and n-hexane fractions had more antibacterial activity than butanol fraction based on Duncan test. Minimum Inhibitory Concentrations (MICs of methanol, n-hexane and butanol fractions from leaves of sweet basil were 39.1, 41 and 117.2 ?g disc-1, respectively. This study demonstrated that methanol, n-hexane and butanol fractions of sweet basil inhibited the growth of H. pylori strains in vitro.

Outbreak of cyclosporiasis in British Columbia associated with imported Thai basil.  

Science.gov (United States)

Sporadic outbreaks of cyclosporiasis, a common cause of protracted diarrhoea in underdeveloped countries, are often undetected and undiagnosed in industrial countries. In May 2001, an outbreak of Cyclospora cayetanensis gastroenteritis was identified in British Columbia, Canada, with 17 reported cases. We conducted a case-control study involving 12 out of the 17 reported and confirmed case patients. Eleven (92%) of the patients had consumed Thai basil, an essential ingredient in Vietnamese cuisine, compared to 3 out of 16 (19%) of the control patients (P = 0.003). Trace-back investigations implicated Thai basil imported via the United States as the vehicle for this outbreak. This is the first documented sporadic outbreak of cyclosporiasis linked to Thai basil in Canada, and the first outbreak of cyclosporiasis identified in an ethnic immigrant population. This outbreak provides the opportunity to increase our understanding of this emerging pathogen and improve on our prevention and control for future outbreaks. PMID:15724706

Aroma characterisation and UV elicitation of purple basil from different plant tissue cultures.  

Science.gov (United States)

Exposure to stressful environmental conditions can induce severe metabolic variations in basil (Ocimum basilicum) aroma. The aromatic profiles of Dark Opal and Red Rubim varieties (in vivo plants, in vitro shoots, callus, and suspension cultures) were investigated for the first time. The established calli represented the most interesting miniaturised aromatic plant systems, as they were able to emit many typical basil volatiles with very low amounts of phenylpropanoids (1-2%). The hydrocarbon monoterpenes and oxygenated volatiles emitted from calli of both varieties were greatly and conversely affected by UV-C and UV-B, in comparison with the non-irradiated samples. As calli of both varieties still maintained very low levels of phenylpropanoids even after UV elicitation, they might be regarded not only as efficient in vitro plant models to study volatile compounds under UV stress conditions, but also as safe aromatic biomass in comparison with in vivo basil plants.

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

Science.gov (United States)

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

Uranium veins in Portugal  

International Nuclear Information System (INIS)

Vein-type uranium deposits in Portugal demonstrate a broad temporal and physical spectrum from intragranitic hydrothermal jasper-type veins formed at moderately high temperatures, through lower temperature quartz veins and peribatholithic disseminated mineralization of 'Iberian-type', to undoubted supergene enrichments in surface-related planar traps such as weathered basic dikes. All appear to be in close spatial relationship to 'fertile' Hercynian granites in which uraninite of low thorium content is the main contributor to the enriched uranium levels. The availability of this large source of labile uranium, a pervasive fracture network and a series of tectonic and intrusive events which could generate hydrothermal circulation, allow several alternative genetic models for the mineralization. It now appears that the classic hydrothermal pitchblende veins within the granite are most likely of late-Hercynian age. Many of the mineralogical and depositional characteristics of the lower temperature 'Iberian-type' deposits suggest a temporal continuity to this mineralization but, as yet, no supporting age data are available. It is conceded, therefore, that a considerable time-gap could occur between the two episodes, with the peribatholithic mineralization resulting from later rejuvenation of the hydrothermal convective system.

Treatment of varicose veins.  

Science.gov (United States)

Varicose veins (VVs) are the most common manifestation of chronic venous insufficiency, affecting 25% of women and 15% of men. Reticular veins and telangiectasias (spider veins) are found in more than 80% of the general population. VVs produce symptoms of pain, swelling, heaviness, fatigue, and pruritus and predispose patients to complications including bleeding, superficial thrombophlebitis, and ulcerations that interfere with activities of daily living and result in lost time from work. Current treatments for VVs include conservative measures, and when these are unsuccessful, more invasive surgical and endovenous interventions primarily aimed at reducing venous hypertension and preventing progression to chronic inflammation and ulcerations. Surgical procedures including saphenous vein stripping, ligation of the saphenofemoral junction, and ambulatory phlebectomy are effective in the treatment of VVs but are associated with a high complication rate and recovery time. Emerging endovenous therapies, including endovenous laser therapy, radiofrequency ablation, and endovenous foam sclerotherapy, have shown similar efficacy in the treatment of VVs compared with more invasive surgical procedures, with lower complication rates and less time lost from work.

Postpartum Ovarian Vein Thrombosis  

Science.gov (United States)

Background: Ovarian vein thrombosis (OVT) is a rare but potentially serious postpartum complication, which occurs in 0.05% to 0.18% of pregnancies and is diagnosed on the right side in 80% to 90% of the cases. Case Report: A 32-year-old woman presented at 15 days postpartum to our emergency department with severe abdominal pain, fever, and abdominal distension. Abdominal examination revealed right lower quadrant pain with rebound tenderness. The plain abdominal radiography evidenced a diffuse fecal stasis; abdominal ultrasound showed the presence of free fluid in the Douglas’ pouch and between small bowel loops. Diagnosis of acute appendicitis was made. The patient immediately underwent explorative laparoscopy; at surgery, a woody tumoration consistent with right ovarian vein thrombosis was found. Laparoscopic ultrasound confirmed the diagnosis. Anticoagulation therapy and antibiotics were instituted. CT-scan confirmed the presence of thrombosis up to the vena cava. The patient was discharged on postoperative day 4. At 1-month follow-up, she remained stable and symptom free. Discussion: Even though postpartum ovarian vein thrombosis is rare, recognition and treatment is needed to institute adequate therapy and avoid potential serious sequelae. The diagnosis can be established by ultrasound, CT scan, and MRI examinations, although, as in the case described, the limitation of ultrasound includes obscuration of the gonadic vein by overlying bowel gas. Conclusion: OVT should be considered in any woman in the postpartum period with lower abdominal pain, fever, and leucocytosis. PMID:21902992

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

Directory of Open Access Journals (Sweden)

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

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.)

SNP discovery by mismatch-targeting of Mu transposition  

Science.gov (United States)

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

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.

Varicosity of the pulmonary veins  

International Nuclear Information System (INIS)

Varicosity of the pulmonary veins is a rare anomaly of the pulmonary vascular system. The varices do not usually change in size over years, do not cause symptoms and need no therapy. However, raised left atrial pressure can cause increase in the diameter of pulmonary vein varices. A case of lung vein varicosity in the right middle and upper lobe associated with coarctation of the aorta and an anomalous upper-middle lobe vein was observed over a period of 10 years. Increase in left atrial pressure (aortic and relative mitral regurgitation) led to enlargement of the pulmonary veins. (orig.)

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.

Sorting by Prefix Reversals and Prefix Transpositions with Forward March  

CERN Document Server

Sorting permutations by reversals and/or transpositions is an important genome rearrangement problem in computational molecular biology. From theoretical point of view, finding efficient algorithms for this problem and its variations are quite challenging. In this paper we consider the problem of sorting unsigned permutations by prefix reversals and prefix transpositions, where a prefix reversal or a prefix transposition is applied always at the unsorted suffix of the given permutation. For this problem we first present a 3-approximation algorithm, which performs close to 2 in practice. We further analyze the problem in more practical way and consider the variation where a certain number of prefix reversals are forced to happen in the sorting process. Here we achieve an improved approximation ratio of $(3-\\frac{3r}{b(\\pi)+r})$, where $r$ is the number of prefix reversals that must happen in the sorting, when possible, and $b(\\pi)\\geq 2r$ is the number of breakpoints in the given permutation. Again, in this va...

Bounded Rationality in Transposition Processes : The Case of the European Patient Rights Directive  

DEFF Research Database (Denmark)

Studies explaining the timeliness and correctness of the transposition of EU directives into national legislation have provided rather inconclusive findings. They do not offer a clear-cut prediction concerning the transposition of the patients’ rights directive, which is one of the first that concerns the organisation and financing of national healthcare systems. This article applies the perspective of bounded rationality to explain (irregularities in) the timely and correct transposition of EU directives. The cognitive and organisational constraints long posited by the bounded rationality perspective may affect the commonly employed explanatory factors of administrative capacities, misfit and the heterogeneity of preferences among veto players. To prevent retrospective rationalisation of the transposition process, this paper traces this process as it unfolded in Denmark and the Netherlands. As bounded rationality is apparent in the transposition processes in these relatively well-organised countries, future transposition studies should devote greater consideration to the bounded rationality perspective.

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.

Eight experimental trials were carried out during 2007 and 2008 to evaluate the efficacy of different fungicides against downy mildew of lettuce (Bremia lactucae) and basil (Peronospora belbahrii) under greenhouse conditions, at temperatures ranging from 19 to 24 degrees C. The mixture fluopicolide (fungicide belonging to the + propamocarb hydrochloride (fungicide belonging to the new chemical class of acyl-picolides) was compared with metalaxyl m + copper, zoxamide + mancozeb, iprovalicarb + Cu, fenamidone + fosetyl-Al and azoxystrobin. Two treatments were carried out at 8-12 day interval on lettuce and basil. The artificial inoculation of B. lactucae on lettuce (cv Cobham Green) and P. belbahrii. on basil (cv Genovese gigante) was carried out by using 1 x 10(5) CFU/ml 24 h after the first treatment. In the presence of a medium-high disease severity, all fungicides tested in these trials were effective against downy mildew on lettuce and basil as the other fungicides already available. The importance of the availability of a number of different chemicals to control downy mildews is discussed. PMID:20222581

Diversity in chemical composition and yield of essential oil from two Iranian landraces of sweet basil  

Directory of Open Access Journals (Sweden)

Full Text Available Ocimum basilicum L. belongs to the family Lamiaceae is an herb that is extensively cultivated in some countries. 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.

Venous variations in neck region: cephalic vein  

Directory of Open Access Journals (Sweden)

Full Text Available The cephalic vein lies in the deltopectoral groove, and passes throught the infraclavicular fossa, and drains into the axillary vein. It may communicate with the external jugular vein via a branch positioned anterior to the clavicle before emptying into the axillary vein. In this case multiple variations were found in the veins of the neck region: cephalic vein, jugular vein, and facial vein.The cephalic vein in the left side passed between the clavicular and sternal heads of the pectoralis major muscle. The cephalic and the external jugular veins were joined and made a common trunk at the anterior border of clavicle. Then opened into the junction of the subclavian and internal jugular veins below the clavicle. The facial and retromandibular veins were built up the external jugular vein. The anterior jugular vein was absent.

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.

Splenic transposition is superior to caudal shunt as a model of murine total hepatic ischemia.  

Science.gov (United States)

Murine total hepatic ischemia (THI) followed by reperfusion without shunting of the portal vein induces significant lethality in rodents due to intestinal congestion. Two methods have been promulgated to study THI and reperfusion in mice without intestinal congestion: subcutaneous splenic transposition which creates a portosystemic shunt via epigastric vessels, and a caudal shunt with 30% hepatectomy, which creates a portosystemic shunt via the small remnant of remaining caudal lobe. We compared outcome, inflammatory response and hepatic injury due to THI and reperfusion in these two models. Female C57BL/6 mice underwent ST, caudal shunt or no surgery prior to having 30 min of total hepatic ischemia followed by 60 min of reperfusion. Survival, surgical complications, serum AST/ALT and IL-6 were determined. Apoptotic and necrotic hepatocytes were identified by morphological criteria. Complication rates for the ST and caudal shunt procedures were 6.7 and 20%, respectively. Subsequent mortality rates following THI and 60 min reperfusion were 5.9 and 50% in mice with ST and caudal shunt, respectively. Both groups had elevated serum AST/ALT concentrations. However, in mice undergoing caudal shunt, AST/ALT levels were also significantly increased even without THI. The number of apoptotic hepatocytes after THI and reperfusion in mice following caudal shunt was significantly higher compared with those of ST (P<0.001). Both ST and caudal shunt can be used in models of THI and reperfusion to prevent significant lethality due to intestinal congestion. However, ST is a simple, safe and suitable model, whereas caudal shunt requires manipulation of the liver, and is associated with significant hepatic injury and morbidity. PMID:15558060

Characterisation of organic and conventional sweet basil leaves using chromatographic and flow-injection mass spectrometric (FIMS) fingerprints combined with principal component analysis.  

Science.gov (United States)

Sweet basil, Ocimum basilicum, is one of the most important and wildly used spices and has been shown to have antioxidant, antibacterial, and anti-diarrheal activities. In this study, high performance liquid chromatographic (HPLC) and flow-injection mass spectrometric (FIMS) fingerprinting techniques were used to differentiate organic and conventional sweet basil leaf samples. Principal component analysis (PCA) of the fingerprints indicated that both HPLC and FIMS fingerprints could effectively detect the chemical differences in the organic and conventional sweet basil leaf samples. This study suggested that the organic basil sample contained greater concentrations of almost all the major compounds than its conventional counterpart on a per same botanical weight basis. The FIMS method was able to rapidly differentiate the organic and conventional sweet basil leaf samples (1min analysis time), whereas the HPLC fingerprints provided more information about the chemical composition of the basil samples with a longer analytical time.

The management of cosmetic vein problems requires a very different approach than that for the majority of most other vascular disorders that occur in a vascular surgery practice. This article focuses on the business aspects of a cosmetic vein practice, with particular attention to the uniqueness of these issues. Managing patient expectations is critical to the success of a cosmetic vein practice. Maneuvering within the insurance can be difficult and frustrating for both the patient and the practice. Practices should use cost accounting principles to evaluate the success of their vein work. Vein surgery--especially if performed within the office--can undergo an accurate break-even analysis to determine its profitability. PMID:17911565

Methyl jasmonate-elicited transcriptional responses and pentacyclic triterpene biosynthesis in sweet basil.  

Science.gov (United States)

Sweet basil (Ocimum basilicum) is well known for its diverse pharmacological properties and has been widely used in traditional medicine for the treatment of various ailments. Although a variety of secondary metabolites with potent biological activities are identified, our understanding of the biosynthetic pathways that produce them has remained largely incomplete. We studied transcriptional changes in sweet basil after methyl jasmonate (MeJA) treatment, which is considered an elicitor of secondary metabolites, and identified 388 candidate MeJA-responsive unique transcripts. Transcript analysis suggests that in addition to controlling its own biosynthesis and stress responses, MeJA up-regulates transcripts of the various secondary metabolic pathways, including terpenoids and phenylpropanoids/flavonoids. Furthermore, combined transcript and metabolite analysis revealed MeJA-induced biosynthesis of the medicinally important ursane-type and oleanane-type pentacyclic triterpenes. Two MeJA-responsive oxidosqualene cyclases (ObAS1 and ObAS2) that encode for 761- and 765-amino acid proteins, respectively, were identified and characterized. Functional expressions of ObAS1 and ObAS2 in Saccharomyces cerevisiae led to the production of ?-amyrin and ?-amyrin, the direct precursors of oleanane-type and ursane-type pentacyclic triterpenes, respectively. ObAS1 was identified as a ?-amyrin synthase, whereas ObAS2 was a mixed amyrin synthase that produced both ?-amyrin and ?-amyrin but had a product preference for ?-amyrin. Moreover, transcript and metabolite analysis shed light on the spatiotemporal regulation of pentacyclic triterpene biosynthesis in sweet basil. Taken together, these results will be helpful in elucidating the secondary metabolic pathways of sweet basil and developing metabolic engineering strategies for enhanced production of pentacyclic triterpenes.

The relationship between growth stages and aroma composition of lemon basil Ocimum citriodorum Vis.  

Science.gov (United States)

Volatiles from infusions of lemon basil Ocimum citriodorum Vis were evaluated by SPME-GC/MS. Citral, linalool and estragole were the major constituents. Citral, the major contributor to the lemony flavour, was significantly higher in post-flowering (79%) and full-flowering (65%), it was reduced to 42% at pre-flowering. Linalool was consistent throughout the growth cycle (2-3%). Estragole was higher in pre-flowering representing 15% of the total volatiles present. Linalool levels dropped sharply during the full-flowering and post-flowering stages to 2% and 0.4%, respectively. Volatiles from different parts of lemon basil were evaluated to determine the parts that influence the flavour. The percentage composition of citral for leaves and flowers was 64.5% and 58% for the branches. Linalool was much higher in flowers (13%), followed by 11% in branches and 3% in leaves. The flavour attributes of lemon basil infusions can be improved by incorporating aerial branches and flowers in the tea. PMID:24444959

Phenylpropanoid biosynthesis in leaves and glandular trichomes of basil (Ocimum basilicum L.).  

Science.gov (United States)

Basil (Ocimum basilicum L.) essential oil phenylpropenes are synthesized and accumulate in peltate glandular trichomes and their content and composition depend on plant developmental stage. Studies on gene expression and enzymatic activity indicate that the phenylpropene biosynthetic genes are developmentally regulated. In this study, the methylchavicol accumulation in basil leaves and the enzyme activities and gene expression of both chavicol O-methyltransferase (CVOMT) and eugenol O-methyltransferase (EOMT) were investigated in all leaves at four plant developmental stages. Methylchavicol accumulation decreased over time as leaves matured. There was a significant correlation between methylchavicol accumulation and CVOMT (r(2) = 0.88) enzyme activity, suggesting that the levels of biosynthetic enzymes control the essential oil content. CVOMT and EOMT transcript expression levels, which decreased with leaf age, followed the same pattern in both whole leaves and isolated glandular trichomes, providing evidence that CVOMT transcript levels are developmentally regulated in basil glandular trichomes themselves and that differences in CVOMT expression observed in whole leaves are not solely the result of differences in glandular trichome density.

Photoprotection by foliar anthocyanins mitigates effects of boron toxicity in sweet basil (Ocimum basilicum).  

Science.gov (United States)

Boron (B) toxicity is an important agricultural problem in arid environments. Excess edaphic B compromises photosynthetic efficiency, limits growth and reduces crop yield. However, some purple-leafed cultivars of sweet basil (Ocimum basilicum) exhibit greater tolerance to high B concentrations than do green-leafed cultivars. We hypothesised that foliar anthocyanins protect basil leaf mesophyll from photo-oxidative stress when chloroplast function is compromised by B toxicity. Purple-leafed 'Red Rubin' and green-leafed 'Tigullio' cultivars, grown with high or negligible edaphic B, were given a photoinhibitory light treatment. Possible effects of photoabatement by anthocyanins were simulated by superimposing a purple polycarbonate filter on the green leaves. An ameliorative effect of light filtering on photosynthetic quantum yield and on photo-oxidative load was observed in B-stressed plants. In addition, when green protoplasts from both cultivars were treated with B and illuminated through a screen of anthocyanic protoplasts or a polycarbonate film which approximated cyanidin-3-O-glucoside optical properties, the degree of photoinhibition, hydrogen peroxide production, and malondialdehyde content were reduced. The data provide evidence that anthocyanins exert a photoprotective role in purple-leafed basil mesophyll cells, thereby contributing to improved tolerance to high B concentrations. PMID:24903358

Learning from the pulmonary veins.  

Science.gov (United States)

The purpose of this article is to review the basic embryology and anatomy of the pulmonary veins and the various imaging techniques used to evaluate the pulmonary veins, as well as the radiologic findings in diseases affecting these structures. Specific cases highlight the clinical importance of the imaging features, particularly the findings obtained with multidetector computed tomography (CT). Pulmonary vein disease can be broadly classified into congenital or acquired conditions. Congenital disease, which often goes unnoticed until patients are adults, mainly includes (a) anomalies in the number or diameter of the vessels and (b) abnormal drainage or connection with the pulmonary arterial tree. Acquired disease can be grouped into (a) stenosis and obstruction, (b) hypertension, (c) thrombosis, (d) calcifications, and (e) collateral circulation. Pulmonary vein stenosis or obstruction, which often has important clinical repercussions, is frequently a result of radiofrequency ablation complications, neoplastic infiltration, or fibrosing mediastinitis. The most common cause of pulmonary venous hypertension is chronic left ventricular failure. This condition is difficult to differentiate from veno-occlusive pulmonary disease, which requires a completely different treatment. Pulmonary vein thrombosis is a rare, potentially severe condition that can have a local or distant cause. Calcifications have been described in rheumatic mitral valve disease and chronic renal failure. Finally, the pulmonary veins can act as conduits for collateral circulation in cases of obstruction of the superior vena cava. Multidetector CT is an excellent modality for imaging evaluation of the pulmonary veins, even when the examination is not specifically tailored for their assessment. PMID:23842969

Induction of transpositions of MGE Dm412 by ?-radiation in an isogenic line of Drosophila melanogaster  

International Nuclear Information System (INIS)

In an isogenic line of Drosophila, transpositions of mobile genetic elements (MGE) Dm412 were induced by ?-radiation at doses of 300, 800, and 1300 R. The rates of induced transpositions were (for each dose, respectively) 3.9 x 10-3, 1.0 x 10-2, and 1.87 x 10-2 events per occupied site per haploid genome of the isogenic line per generation. Thus, the transposition rate increased linearly with the radiation dose. The specific rate of ?-radiation-induced transpositions was (1.3 ± 0.6) x 10-5 per occupied site per haploid genome of the isogenic line per Roentgen per generation. ?-Radiation-induced hot transposition sites and haplotypes, very similar to those induced by heat shock, were found. It was suggested that the mechanism of induction by ?-radiation involves the heat shock system. Thus, it is more similar to the mechanism of temperature induction than to the direct mutational effect of ?-radiation. Estimates of induced transposition rates per genome for each dose were calculated as 1.1, 3.0, and 5.6 events, respectively, per genome per generation. This level probably corresponds to the subthreshold level of genomes near the open-quotes catastrophic border of transpositional losses.close quotes 21 refs., 1 fig., 4 tabs

Toxicity of basil oil constituents and related compounds and the efficacy of spray formulations to Dermatophagoides farinae (Acari: Pyroglyphidae).  

Science.gov (United States)

Pyroglyphid house dust mites are the most common cause of allergic symptoms in humans. An assessment was made of the toxicity of basil, Ocimum basilicum L, essential oil, 11 basil oil constituents, seven structurally related compounds, and another 22 previously known basil oil constituents to adult American house dust mites, Dermatophagoides farinae Hughes. The efficacy of four experimental spray formulations containing basil oil (1, 2, 3, and 4% sprays) was also assessed. Results were compared with those of two conventional acaricides benzyl benzoate and N,N-diethyl-3-methylbenzamide. The active principles of basil oil were determined to be citral, alpha-terpineol, and linalool. Citral (24 h LC50, 1.13 microg/cm2) and menthol (1.69 microg/cm2) were the most toxic compounds, followed by methyl eugenol (5.78 microg/cm2). These compounds exhibited toxicity greater than benzyl benzoate (LC50, 8.41 microg/cm2) and N,N-diethyl-3-methylbenzamide (37.67 microg/cm2). Potent toxicity was also observed with eugenol, menthone, spathulenol, alpha-terpineol, nerolidol, zerumbone, and nerol (LC50, 12.52-21.44 microg/cm2). Interestingly, the sesquiterpenoid alpha-humulene, lacking only the carbonyl group present in zerumbone, was significantly less effective than zerumbone, indicating that the alpha,beta-unsaturated carbonyl group of zerumbone is a prerequisite component for toxicity. These compounds were consistently more toxic in closed versus open containers, indicating that their mode of delivery was largely a result of vapor action. Basil oil applied as 3 and 4% sprays provided 97 and 100% mortality against the mites, respectively, whereas permethrin (cis:trans, 25:75) 2.5 g/liter spray treatment resulted in 17% mortality. Our results indicate that practical dust mite control in indoor environments can be achieved by basil oil spray formulations (3 and 4% sprays) as potential contact-action fumigants. PMID:24897858

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.

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.

The transposition of musical knowledge in intellectual education  

Directory of Open Access Journals (Sweden)

Full Text Available The construction of European citizenship in the era of complexity requires that the transmission of knowledge be directed towards an intellectual formation, that is, the ‘shaping’ of a critical mind, one that is able to problematize, and hence to discern. This can be achieved by educating towards comprehension. In facing this issue, musicologists ask themselves ‘what to teach’ and ‘how to teach’ it, in order to prepare students to the comprehension of music – these questions form the basis of music didactics as the science of ‘transposing’ savoir savant (learned knowledge into savoir enseigné (didactic knowledge. The paper proposes a model appraoch to music comprehension, through the didactic transposition of a piece by Claude Debussy, La cathédrale engloutie. The example is based on a strategy developed by musicological and methodological-didactic research, and focuses on the continuity among listening, music performance, and music history.

A Vein Map Biometric System  

Directory of Open Access Journals (Sweden)

Full Text Available There is increasing demand world-wide, from government agencies and the private sector for cutting-edge biometric security technology that is difficult to breach but userfriendly at the same time. Some of the older tools, such as fingerprint, retina and iris scanning, and facial recognition software have all been found to have flaws and often viewed negatively because of many cultural and hygienic issues associated with them. Comparatively, mapping veins as a human barcode, a new technology, has many advantages over older technologies. Specifically, reproducing a three-dimensional model of a human vein system is impossible to replicate. Vein map technology is distinctive because of its state-of-the-art sensors are only able to recognize vein patterns if hemoglobin is actively flowing through the person

Matrix-derived combination effect and risk assessment for estragole from basil-containing plant food supplements (PFS).  

Science.gov (United States)

Basil-containing plant food supplements (PFS) can contain estragole which can be metabolised into a genotoxic and carcinogenic 1'-sulfoxymetabolite. This study describes the inhibition of sulfotransferase (SULT)-mediated bioactivation of estragole by compounds present in basil-containing PFS. Results reveal that PFS consisting of powdered basil material contain other compounds with considerable in vitro SULT-inhibiting activity, whereas the presence of such compounds in PFS consisting of basil essential oil was limited. The inhibitor in powdered basil PFS was identified as nevadensin. Physiologically based kinetic (PBK) modeling was performed to elucidate if the observed inhibitory effects can occur in vivo. Subsequently, risk assessment was performed using the Margin of Exposure (MOE) approach. Results suggest that the consequences of the in vivo matrix-derived combination effect are significant when estragole would be tested in rodent bioassays with nevadensin at ratios detected in PFS, thereby increasing MOE values. However, matrix-derived combination effects may be limited at lower dose levels, indicating that the importance of matrix-derived combination effects for risk assessment of individual compounds should be done on a case-by-case basis considering dose-dependent effects. Furthermore, this study illustrates how PBK modeling can be used in risk assessment of PFS, contributing to further reduction in the use of experimental animals. PMID:23959103

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.

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.

Weighted genomic distance can hardly impose a bound on the proportion of transpositions  

CERN Document Server

Genomic distance between two genomes, i.e., the smallest number of genome rearrangements required to transform one genome into the other, is often used as a measure of evolutionary closeness of the genomes in comparative genomics studies. However, in models that include rearrangements of significantly different "power" such as reversals (that are "weak" and most frequent rearrangements) and transpositions (that are more "powerful" but rare), the genomic distance typically corresponds to a transformation with a large proportion of transpositions, which is not biologically adequate. Weighted genomic distance is a traditional approach to bounding the proportion of transpositions by assigning them a relative weight {\\alpha} > 1. A number of previous studies addressed the problem of computing weighted genomic distance with {\\alpha} \\leq 2. Employing the model of multi-break rearrangements on circular genomes, that captures both reversals (modelled as 2-breaks) and transpositions (modelled as 3-breaks), we prove th...

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

Antifungal activity of the basil (Ocimmum basilicum L. extract on Penicillium aurantiogriseum, P. glabrum, P. chrysogenum, and P. brevicompactum  

Directory of Open Access Journals (Sweden)

Full Text Available This study was aimed at investigating the antifungal potential of basil (Ocimmum basilicum L. extract against toxin-producing Penicillium spp. (P. aurantiogriseum, P. glabrum, P. chrysogenum, and P. brevicompactum isolated from food. The basil extract composition was determined by the GC-MS method. The major component identified in the extract was estragole (86.72%. The determination of the antifungal activity of basil extract on Penicillium spp. was performed using the agar plate method. Basil extract reduced the growth of Penicillium spp. at all applied concentration levels (0.16, 0.35, 0.70, and 1.50 mL/100mL with the colony growth inhibition from 3.6 (for P. glabrum to 100% (for P. chrysogenum. The highest sensitivity showed P. chrysogenum, where the growth was completely inhibited at the basil extract concentration of 1.50 mL/100mL. The growth of other Penicillium spp. was partially inhibited with the colony growth inhibition of 63.4 % (P. brevicompactum, 67.5% (P. aurantiogriseum, and 71.7% (P. glabrum. Higher concentrations (0.70 and 1.50 mL/100mL reduced the growth of the aerial mycelium of all tested Penicillium species. In addition, at the same extract concentrations, the examination of microscopic preparation showed the deformation of hyphae with the frequent occurrence of fragmentations and thickenings, occurrence of irregular vesicle, frequently without metulae and phialides, enlarged metulae. The results obtained in this investigation point to the possibility of using basil extract for the antifungal food protection. [Projekat Ministarstva nauke Republike Srbije, br. TR-31017

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.

Portal vein thrombosis in cirrhosis.  

Science.gov (United States)

Portal vein thrombosis (PVT) is being increasingly recognized in patients with advanced cirrhosis and in those undergoing liver transplantation. Reduced flow in the portal vein is probably responsible for clotting in the spleno-porto-mesenteric venous system. There is also increasing evidence that hypercoagulability occurs in advanced liver disease and contributes to the risk of PVT. Ultrasound based studies have reported a prevalence of PVT in 10-25% of cirrhotic patients without hepatocellular carcinoma. Partial thrombosis of the portal vein is more common and may not have pathophysiological consequences. However, there is high risk of progression of partial PVT to complete PVT that may cause exacerbation of portal hypertension and progression of liver insufficiency. It is thus, essential to accurately diagnose and stage PVT in patients waiting for transplantation and consider anticoagulation therapy. Therapy with low molecular weight heparin and vitamin K antagonists has been shown to achieve complete and partial recanalization in 33-45% and 15-35% of cases respectively. There are however, no guidelines to help determine the dose and therapeutic efficacy of anticoagulation in patients with cirrhosis. Anticoagulation therapy related bleeding is the most feared complication but it appears that the risk of variceal bleeding is more likely to be dependent on portal pressure rather than solely related to coagulation status. TIPS has also been reported to restore patency of the portal vein. Patients with complete PVT currently do not form an absolute contraindication for liver transplantation. Thrombectomy or thromboendovenectomy is possible in more than 75% of patients followed by anatomical end-to-end portal anastomosis. When patency of the portal vein and/or superior mesenteric vein is not achieved, only non-anatomical techniques (reno-portal anastomosis or cavo-portal hemitransposition) can be performed. These techniques, which do not fully reverse portal hypertension, are associated with higher morbidity and mortality risks in the short term. PMID:25755579

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

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...

Interrupting connection of superficial and deep veins of the upper extremity at the elbow for creation of hemodialysis arteriovenous fistulas  

Directory of Open Access Journals (Sweden)

Full Text Available We hypothesized that interrupting the connection between superficial and deep veins of the upper extremity at the elbow for creation of hemodialysis arteriovenous fistulas (AVFs, in addition to adequate dilation of the elbow veins, will reduce the risk of steal syndrome and venous hypertension. In this prospective study over a period of one year, patients who were candidates for creation of elbow AVFs based on Doppler ultrasound findings and physical exa-mination, were enrolled into the study. For creation of AVFs, based on the anatomy of the vessels, side-to-side or end-to-side anastomosis between the brachial artery and either cephalic or median antecubital or basilic veins was performed. In some cases, Gracz AVF was created. For inter-rupting the connection between superficial and deep veins, the perforating vein was either ligated or used for anastomosis. The patients were then followed-up regarding patency rate of the AVF and complications. AVFs were created in 50 patients and the duration of follow-up varied from one to eight months. About 56% (n = 28 of the patients had history of failed AVF or arterio-venous graft and 48% (n = 24 of them had history of insertion of a dual-lumen catheter for hemo-dialysis. Neuromuscular problem (n=1 and infection (n=1 were the observed complications. None of the patients developed steal syndrome or venous hypertension. At the end of the study, 47 AVFs (94% were patent and adequate. Our study suggests that interrupting the connection between the superficial and deep venous systems of the upper extremity can reduce the risk of development of steal syndrome and venous hypertension despite side-to-side anastomosis. These techniques provided acceptable patency rate for elbow AVFs.

Differential Production of meta Hydroxylated Phenylpropanoids in Sweet Basil Peltate Glandular Trichomes and Leaves Is Controlled by the Activities of Specific Acyltransferases and Hydroxylases1  

Science.gov (United States)

Sweet basil (Ocimum basilicum) peltate glandular trichomes produce a variety of small molecular weight phenylpropanoids, such as eugenol, caffeic acid, and rosmarinic acid, that result from meta hydroxylation reactions. Some basil lines do not synthesize eugenol but instead synthesize chavicol, a phenylpropanoid that does not contain a meta hydroxyl group. Two distinct acyltransferases, p-coumaroyl-coenzyme A:shikimic acid p-coumaroyl transferase and p-coumaroyl-coenzyme A:4-hydroxyphenyllactic acid p-coumaroyl transferase, responsible for the production of p-coumaroyl shikimate and of p-coumaroyl 4-hydroxyphenyllactate, respectively, were partially purified and shown to be specific for their substrates. p-Coumaroyl-coenzyme A:shikimic acid p-coumaroyl transferase is expressed in basil peltate glands that are actively producing eugenol and is not active in glands of noneugenol-producing basil plants, suggesting that the levels of this activity determine the levels of synthesis of some meta-hydroxylated phenylpropanoids in these glands such as eugenol. Two basil cDNAs encoding isozymes of cytochrome P450 CYP98A13, which meta hydroxylates p-coumaroyl shikimate, were isolated and found to be highly similar (90% identity) to the Arabidopsis homolog, CYP98A3. Like the Arabidopsis enzyme, the basil enzymes were found to be very specific for p-coumaroyl shikimate. Finally, additional hydroxylase activities were identified in basil peltate glands that convert p-coumaroyl 4-hydroxyphenyllactic acid to its caffeoyl derivative and p-coumaric acid to caffeic acid.

Potential Activity of Basil Plants as a Source of Antioxidants and Anticancer Agents as Affected by Organic and Bio-organic Fertilization  

Directory of Open Access Journals (Sweden)

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.

Effect of silica Nanoparticles on Basil (Ocimum basilicum Under Salinity Stress  

Directory of Open Access Journals (Sweden)

Full Text Available Application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. Uncontrolled application of chemical fertilizer and pesticides has caused many problems to human health and domestic animals. Nanofertilizers application could be a suitable way to reduce these problems. Accordingly, in order to assess the silicon nanoparticles effect on some vegetative features of basil under salinity stress, a factorial experiment based on a completely randomized design with three replications was conducted in greenhouse condition. Treatments included different levels of silicon fertilizer (without silicon, normal silicon fertilizer and silicon nanoparticles and salinity stress (1, 3 and 6 ds/m. Physiological traits (chlorophyll and proline content of leaves and morphological traits (shoot fresh weight and dry weight were investigated in this study. Results showed a significant reduction in growth and development indices due to the salinity stress.  Leaf dry and fresh weight reduced by increment in NaCl concentration while significantly (P?0.01 increased with silicon nanoparticles application. The chlorophyll content reduced in salinity stress, but increased by silicon nanoparticles treatment. Proline content increased under salinity stress which was a response to stress. Moreover, proline increased by silicon nanoparticles which was due to tolerance induction in plant. Silicon nanoparticles application reduced the pollution effects originated from salinity in Basil.

The effects of plant growth regulators and L-phenylalanine on phenolic compounds of sweet basil.  

Science.gov (United States)

The effects of methyl jasmonate (MeJA), spermine (Spm), epibrassinolide (EBL) and l-phenylalanine on sweet basil (Ocimum basilicum L.) were studied to determine the amount of phenolic compounds and enzymatic activity of phenylalanine ammonia-lyase (PAL). Total phenolic and total flavonoid contents of sweet basils were determined by a spectrophotometer, and individual phenolic compounds and activity of PAL were analysed by HPLC/UV. The highest total phenolic (6.72 mg GAE/g) and total flavonoid contents (0.92 mg QE/g) obtained from 1.0 mM Spm+MeJA application. Rosmarinic acid (RA) and caffeic acid contents significantly enhanced after the applications but no such differences observed in chicoric acid content or PAL activity. RA was the main phenolic acid in all samples and its concentration varied from 1.04 to 2.70 mg/gFW. As a result the combinations of Spm+MeJA and EBL+MeJA can induce secondary metabolites effectively and those interactions play important role in the production of phytochemicals in plants.

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

Leiomyosarcoma of the Adrenal Vein  

Directory of Open Access Journals (Sweden)

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

Survival of Salmonella and Escherichia coli O157:H7 on Strawberries, Basil, and Other Leafy Greens during Storage.  

Science.gov (United States)

The survival of Salmonella and Escherichia coli O157:H7 on strawberries, basil leaves, and other leafy greens (spinach leaves, lamb and butterhead lettuce leaves, baby leaves, and fresh-cut iceberg lettuce) was assessed at cold (survival experiment stopped before day 7, as die-off of both pathogens below the lower limit of detection was achieved or spoilage occurred. At 22°C, strawberries were moldy after 2 or 4 days. At that time, a 1- to 2-log reduction of both pathogens had occurred. A restricted die-off (on average 1.0 log) and increase (on average , 0.5 log) of both pathogens on basil leaves occurred after 7 days of storage at 7 and 22°C, respectively. On leafy greens, a comparable decrease as on basil was observed after 3 days at 7°C. At 22°C, both pathogens increased to higher numbers on fresh-cut iceberg and butterhead lettuce leaves (on average 1.0 log), probably due to the presence of exudates. However, by using spot inoculation, the increase was rather limited, probably due to minimized contact between the inoculum and cell exudates. Avoiding contamination, in particular, at cultivation (and harvest or postharvest) is important, as both pathogens survive during storage, and strawberries, basil, and other leafy green leaves are consumed without inactivation treatment.

Renal arcuate veins: new microangiogrphic observations

Standard references state that arcuate veins at the corticomedullary junction form continuous arcades. Because some preliminary anatomic observations seemed to disagree with this traditional teaching, the arcuate veins were systematically studied in normal human kidneys. Microangiographic studies indicate that, unlike the occasional anastomoses that exist between proximal interlobar and segmental veins, arcuate venous communications in human are extremely rare. Arcuate veins, like the corresponding arteries, should be considered end vessels

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.

Diverse Geological Applications For Basil: A 2d Finite-deformation Computational Algorithm  

Science.gov (United States)

Geological processes are often characterised by large finite-deformation continuum strains, on the order of 100% or greater. Microstructural processes cause deformation that may be represented by a viscous constitutive mechanism, with viscosity that may depend on temperature, pressure, or strain-rate. We have developed an effective com- putational algorithm for the evaluation of 2D deformation fields produced by Newto- nian or non-Newtonian viscous flow. With the implementation of this algorithm as a computer program, Basil, we have applied it to a range of diverse applications in Earth Sciences. Viscous flow fields in 2D may be defined for the thin-sheet case or, using a velocity-pressure formulation, for the plane-strain case. Flow fields are represented using 2D triangular elements with quadratic interpolation for velocity components and linear for pressure. The main matrix equation is solved by an efficient and compact conjugate gradient algorithm with iteration for non-Newtonian viscosity. Regular grids may be used, or grids based on a random distribution of points. Definition of the prob- lem requires that velocities, tractions, or some combination of the two, are specified on all external boundary nodes. Compliant boundaries may also be defined, based on the idea that traction is opposed to and proportional to boundary displacement rate. In- ternal boundary segments, allowing fault-like displacements within a viscous medium have also been developed, and we find that the computed displacement field around the fault tip is accurately represented for Newtonian and non-Newtonian viscosities, in spite of the stress singularity at the fault tip. Basil has been applied by us and colleagues to problems that include: thin sheet calculations of continental collision, Rayleigh-Taylor instability of the continental mantle lithosphere, deformation fields around fault terminations at the outcrop scale, stress and deformation fields in and around porphyroblasts, and deformation of the subducted oceanic slab. Application of Basil to a diverse range of topics is facilitated by the use of command syntax input files that allow most aspects of the calculation to be controlled easily, together with a post-processing package, Sybil, for display and interpretation of the results. Sybil uses a menu-driven graphical interface to access a powerful combination of commands, to- gether with log files that allow repetitive tasks to be more automated

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

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

Effects of drying methods on qualitative and quantitative properties of essential oil of two basil landraces.  

Science.gov (United States)

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.

Quantitatively increased somatic transposition of transposable elements in Drosophila strains compromised for RNAi.  

Science.gov (United States)

In Drosophila melanogaster, small RNAs homologous to transposable elements (TEs) are of two types: piRNA (piwi-interacting RNA) with size 23-29nt and siRNA (small interfering RNA) with size 19-22nt. The siRNA pathway is suggested to silence TE activities in somatic tissues based on TE expression profiles, but direct evidence of transposition is lacking. Here we developed an efficient FISH (fluorescence in Situ hybridization) based method for polytene chromosomes from larval salivary glands to reveal new TE insertions. Analysis of the LTR-retrotransposon 297 and the non-LTR retroposon DOC shows that in the argonaut 2 (Ago2) and Dicer 2 (Dcr2) mutant strains, new transposition events are much more frequent than in heterozygous strains or wild type strains. The data demonstrate that the siRNA pathway represses TE transposition in somatic cells. Nevertheless, we found that loss of one functional copy of Ago2 or Dcr2 increases somatic transpositions of the elements at a lower level depending on the genetic background, suggesting a quantitative role for RNAi core components on mutation frequency.

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.

Endovenous laser treatment for primary varicose veins.  

Science.gov (United States)

Venous insufficiency of the lower extremities is a highly prevalent condition. Successful treatment of superficial venous insufficiency will most often necessitate treatment of the saphenofemoral junction incompetence with correction of saphenous vein reflux. In the majority of patients it concerns a reflux of the greater saphenous vein. The standard procedure consists of ligation and stripping of the greater saphenous vein combined with with additional phlebectomies or ligation of insufficient perforant veins if necessary. Although the standard procedure is widely known and accepted, the postoperative morbidity and postoperative limitations of activity are high. In this context minimally invasive percutaneous endovenous techniques were developed to improve the patients comfort and faster resumption of work. Among these, endovenous laser ablation of the greater saphenous vein is a relatively new procedure. Percutaneous introduction of a laser fiber into the incompetent vein and ablation with pulsed laser energy is far less invasive than stripping. PMID:16612909

The natural basil flavonoid nevadensin protects against a methyleugenol-induced marker of hepatocarcinogenicity in male F344 rat.  

Science.gov (United States)

The alkenylbenzene methyleugenol occurs naturally in a variety of spices and herbs, including basil, and their essential oils. At high dose levels methyleugenol induces hepatocarcinogenicity in rodents following bioactivation to 1'-sulfooxymethyleugenol which forms DNA adducts. This study investigated whether the inhibitory effect of the basil flavonoid nevadensin on sulfotransferase (SULT)-mediated bioactivation of methyleugenol observed in vitro would also be reflected in a reduction of DNA adduct formation and a reduction in an early marker for liver carcinogenesis in an 8-week rat study. Co-exposure to methyleugenol and nevadensin orally resulted in a significant inhibition of liver methyleugenol DNA adduct formation and in inhibition of hepatocellular altered foci induction, representing indicators for initiation of neoplasia. These results suggest that tumor formation could be lower in rodent bioassays when methyleugenol would be dosed in a matrix containing SULT inhibitors such as nevadensin compared to experiments using the pure methyleugenol.

The roles of a flavone-6-hydroxylase and 7-O-demethylation in the flavone biosynthetic network of sweet basil.  

Science.gov (United States)

Lipophilic flavonoids found in the Lamiaceae exhibit unusual 6- and 8-hydroxylations whose enzymatic basis is unknown. We show that crude protein extracts from peltate trichomes of sweet basil (Ocimum basilicum L.) cultivars readily hydroxylate position 6 of 7-O-methylated apigenin but not apigenin itself. The responsible protein was identified as a P450 monooxygenase from the CYP82 family, a family not previously reported to be involved in flavonoid metabolism. This enzyme prefers flavones but also accepts flavanones in vitro and requires a 5-hydroxyl in addition to a 7-methoxyl residue on the substrate. A peppermint (Mentha × piperita L.) homolog displayed identical substrate requirements, suggesting that early 7-O-methylation of flavones might be common in the Lamiaceae. This hypothesis is further substantiated by the pioneering discovery of 2-oxoglutarate-dependent flavone demethylase activity in basil, which explains the accumulation of 7-O-demethylated flavone nevadensin.

Anti-inflammatory and antioxidative activity of anthocyanins from purple basil leaves induced by selected abiotic elicitors.  

Science.gov (United States)

This paper investigates changes in the anti-inflammatory and antioxidative activity of anthocyanins from purple basil (Ocimum basilicum L.) leaves induced by arachidonic acid (AA), jasmonic acid (JA) and ?-aminobutyric acid (BABA). The anthocyanins content was significantly increased by all elicitors used in this study; however, no increase was observed in the antioxidant activity of the analyzed extracts. Additionally, a significant decrease by about 50% in the ability to chelate Fe(II) was noted. Further, an increase in the potential anti-inflammatory activity of basil anthocyanins was observed after treatment with each the abiotic elicitor. The IC50 value for lipoxygenase inhibition was almost twice as low after elicitation as that of the control. Also, cyclooxygenase inhibition by anthocyanins was stimulated by abiotic elicitors, except for JA-sample. Additionally, HPLC-analysis indicated that elicitation with AA, JA and BABA caused increases in content most of all anthocyanin compounds. PMID:25442525

Development of the coronary arteries in a murine model of transposition of great arteries.  

Science.gov (United States)

Transposition of great arteries in humans is associated with a wide spectrum of coronary artery patterns. However, no information is available about how this pattern diversity develops. We have studied the development of the coronary arteries in mouse embryos with a targeted mutation of perlecan, a mutation that leads to ventriculo-arterial discordance and complete transposition in about 70% of the embryos. The perlecan-deficient embryos bearing complete transposition showed a coronary artery pattern consisting of right and left coronary arteries arising from the morphologically dorsal and ventral sinuses of Valsalva, respectively. The left coronary artery gives rise to a large septal artery and runs along the ventral margin of the pulmonary root. In the earliest embryos where transposition could be confirmed (12.5 d post coitum), a dense subepicardial vascular plexus is located in this ventral margin. In wild-type mice, however, capillaries are very scarce on the ventral surface of the pulmonary root and the left coronary artery runs dorsally to this root. We suggest that the establishment of the diverse coronary artery patterns is determined by the anatomical arrangement and the capillary density of the peritruncal vascular plexus, a plexus that spreads from the atrio-ventricular groove and grows around the aortic or pulmonary roots depending on the degree of the short-axis aortopulmonary rotation. This simple model, based on very few assumptions, might explain all the observed variation of the coronary artery patterns in humans with transposition, as well as our observations on the perlecan-deficient and the normal mice.

Ultrasound of the fetal veins part 2: Veins at the cardiac level.  

Science.gov (United States)

In recent years the advent of high-resolution and color Doppler ultrasound has enabled a more comprehensive examination of the veins at the cardiac level. These veins include both the superior and inferior vena cava, the pulmonary veins, the azygos vein, the coronary sinus, and the brachiocephalic (or innominate) vein. This article gives a review of the normal and abnormal conditions of the cardiac venous system. Normal anatomy and abnormal findings of these veins are demonstrated by grayscale and color Doppler. Three groups of anomalies are presented: 1) the interrupted inferior vena cava with azygos continuity, 2) the left persisting superior vena cava and 3) the total and partial anomalous pulmonary venous connections. Many of these abnormal findings can be detected by a dedicated examination of the veins during fetal echocardiography, but some anomalies are detectable by focusing on indirect signs such as the compensatory dilation of other veins.

The synergistic preservative effects of the essential oils of sweet basil (Ocimum basilicum L.) against acid-tolerant food microflora.  

Science.gov (United States)

Essential oils extracted by hydrodistillation from five different varieties of Ocimum basilicum L. plants (Anise, Bush, Cinnamon, Dark Opal and a commercial sample of dried basil) were examined for antimicrobial activity against a wide range of foodborne Gram-positive and -negative bacteria, yeasts and moulds by an agar well diffusion method. All five essential oils of basil showed antimicrobial activity against most of the organisms tested with the exception of Flavimonas oryzihabitans and Pseudomonas species. The inhibitory effect of Anise oil, in comparison with mixtures of the predominant components of pure linalool and methyl chavicol, against the acid-tolerant organisms, Lactobacillus curvatus and Saccharomyces cerevisiae, was examined in broth by an indirect impedance method. Synergistic effects between Anise oil, low pH (pH 4.2) and salt (5% NaCl) were determined. The antimicrobial effect of Anise oil was also assessed in a tomato juice medium by direct viable count, showing that the growth of Lact. curvatus and S. cerevisiae was completely inhibited by 0.1% and 1% Anise oil, respectively. The results of the current study indicate the need for further investigations to understand the antimicrobial effects of basil oils in the presence of other food ingredients and preservation parameters.

Full Text Available Microtension test of Costa and Radius veins of damselfly wing was conducted to measure tensile strength and modulus. The specimens were classified into fresh and dry depending on when the samples were prepared and tested. Fresh samples tested immediately after extracting from the fly while the dry samples were tested one year after extraction and stored in a desiccator. Measured load-displacement response and fracture load were used to calculate modulus and strength. Field Emission Scanning Electron Microscope was used to measure the fracture morphology and cross-section of the vein. The results showed that the veins are brittle and fracture surface is flat. The average strength (232 - 285 MPa and modulus (14 - 17 GPa of the Costa and Radius veins were nearly same for both fresh and dry samples. The tensile modulus of the veins was 8% - 10% higher than the indentation (compressive modulus and was nearly the same as that of human bones.

Abbreviated method of determining vein volume in balloon-controlled vein ablation.  

Science.gov (United States)

Traditional surgical ligation and stripping for the treatment of saphenous vein incompetence has been replaced by minimally invasive alternative treatments during the last five years. Endovenous ablation with radiofrequency (RP) and laser (EVL) have proven to be safe, durable, and widely accepted by patients. Catheter-delivered sclerotherapy (CDS) with foam and liquid for ablation of the great saphenous vein is also under investigation. In this technique, vein volume must be measured accurately by ultrasound just prior to the procedure and can require up to 11 diameter measurements. The purpose of this study was to identify an abbreviated method of determining vein volume to expedite associated endovenous procedures. Seventy-five veins were treated in 55 subjects with catheter-directed sclerotherapy in a three-center clinical study using a standardized protocol. Vein volume was carefully calculated by determining vein diameter over the Treatment Length in 4 cm intervals. These measurements were compared to vein volume calculations where only three measurements were taken. Our results suggest that the abbreviated method is capable of significantly reducing the number of diameter measurements without sacrificing accuracy. We found the method produced a vein volume that fell within 1 mL or 15% of the actual vein volume in 80% of cases. The abbreviated method cannot be used with accuracy in veins that are Erratic.

A systems biology investigation of the MEP/terpenoid and shikimate/phenylpropanoid pathways points to multiple levels of metabolic control in sweet basil glandular trichomes.  

Science.gov (United States)

The glandular trichome is an excellent model system for investigating plant metabolic processes and their regulation within a single cell type. We utilized a proteomics-based approach with isolated trichomes of four different sweet basil (Ocimum basilicum L.) lines possessing very different metabolite profiles to clarify the regulation of metabolism in this single cell type. Significant differences in the distribution and accumulation of the 881 highly abundant and non-redundant protein entries demonstrated that although the proteomes of the glandular trichomes of the four basil lines shared many similarities they were also each quite distinct. Correspondence between proteomic, expressed sequence tag, and metabolic profiling data demonstrated that differential gene expression at major metabolic branch points appears to be responsible for controlling the overall production of phenylpropanoid versus terpenoid constituents in the glandular trichomes of the different basil lines. In contrast, post-transcriptional and post-translational regulation of some enzymes appears to contribute significantly to the chemical diversity observed within compound classes for the different basil lines. Differential phosphorylation of enzymes in the 2-C-methyl-d-erythritol 4-phosphate (MEP)/terpenoid and shikimate/phenylpropanoid pathways appears to play an important role in regulating metabolism in this single cell type. Additionally, precursors for different classes of terpenoids, including mono- and sesquiterpenoids, appear to be almost exclusively supplied by the MEP pathway, and not the mevalonate pathway, in basil glandular trichomes.

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.

Characterization of new biodegradable edible film made from basil seed (Ocimum basilicum L.) gum.  

Science.gov (United States)

It is well known that the market for edible films is experiencing remarkable growth and expected to continue. This study investigated the using of basil seed gum (BSG) as a new film-forming material under the influence of addition of glycerol (GLY) as plasticizer. Edible films based on BSG and three different concentrations of GLY (25%, 35%, and 50% w/w BSG) were developed, and their water vapor permeability (WVP), as well as physical, thermal and mechanical properties were measured. The addition of glycerol significantly increased water vapor permeability and solubility of the film (p<0.05). As expected, the increase in GLY concentration from 25% to 50% (w/w) increased the extensibility, but decreased tensile strength. This suggests weaker mechanical strength and higher mobility of polymer chains by plasticizing effect of GLY. The color measurement values showed that increasing the glycerol concentration in polymer matrix caused the b and L values increased while ?E value decreased. The electron scanning micrograph showed plasticized films as smooth, and uniform which lacked pores or cracks compared with those were not plasticized. This study revealed that the BSG had a good potential to be used in producing edible films for various food applications. PMID:24507273

A LINE-type retrotransposon active in meristem stem cells causes heritable transpositions in the sweet potato genome.  

Science.gov (United States)

We isolated a LINE-type retrotransposon, LIb, which showed high transposition activity in sweet potato callus. A copy transposed in the callus was 6303 bp in length and showed key features of a LINE element. Apparently full-length copies sharing the 5' UTR sequence with the 6303-bp copy increased dramatically in the callus as several original copies in the sweet potato genome. These apparently full-length copies had almost identical sequences to other transposed copies, many of which were truncated at the 5' end upon transposition. These results indicate that active LIb is confined to a single LINE family, and that members containing a long functional 5' UTR are present in limited numbers in the sweet potato genome. This is despite their copy numbers being estimated at over 100. The transcription of LIb was not completely suppressed, even in wild-type plants. Spontaneous transpositions were found among local variant lines of the cultivar Koukei14, from which the callus with high LIb activity was derived. Meristem culture of this cultivar appeared to facilitate transpositions of LIb in a mericlone plant. This is the first experimental demonstration of retrotransposition in a plant species without the imposition of cell differentiation. LIb transpositions appear to occur in single founder cells in the meristem because the LIb insertion was found throughout mericlone plant tissues. Transpositional activities in meristem cells might be essential characteristics of plant retrotransposons that cause heritable changes in host plant genomes and genetic systems. PMID:16786293

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

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.

Personal authentication through dorsal hand vein patterns  

Science.gov (United States)

Biometric identification is an emerging technology that can solve security problems in our networked society. A reliable and robust personal verification approach using dorsal hand vein patterns is proposed in this paper. The characteristic of the approach needs less computational and memory requirements and has a higher recognition accuracy. In our work, the near-infrared charge-coupled device (CCD) camera is adopted as an input device for capturing dorsal hand vein images, it has the advantages of the low-cost and noncontact imaging. In the proposed approach, two finger-peaks are automatically selected as the datum points to define the region of interest (ROI) in the dorsal hand vein images. The modified two-directional two-dimensional principal component analysis, which performs an alternate two-dimensional PCA (2DPCA) in the column direction of images in the 2DPCA subspace, is proposed to exploit the correlation of vein features inside the ROI between images. The major advantage of the proposed method is that it requires fewer coefficients for efficient dorsal hand vein image representation and recognition. The experimental results on our large dorsal hand vein database show that the presented schema achieves promising performance (false reject rate: 0.97% and false acceptance rate: 0.05%) and is feasible for dorsal hand vein recognition.

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

Directory of Open Access Journals (Sweden)

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

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 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.

Mesenteric vein thrombosis following laparoscopic appendectomy  

Directory of Open Access Journals (Sweden)

Full Text Available Mesenteric vein thrombosis is an uncommon complication following laparoscopic surgery. A review of the literature has shown that there is a higher incidence of thrombosis following laparoscopic bariatric procedures, including the gastric sleeve procedure and roux-en-y gastric bypass surgery. Additionally, pylephlebitis, thrombosis of portal or mesenteric veins, has been described following perforated appendicitis. However no report has described mesenteric vein thrombosis following laparoscopy for nonperforated appendicitis in the pediatric population. The cause of this thrombosis is hypothesized to be secondary to venous stasis secondary to insufflation during laparoscopy.

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.

Tumor thrombus in the portal vein is refractory to therapy and a serious negative prognostic factor in hepatocellular carcinoma.

An expandable metallic stent was implanted in a patient with severe main portal vein stenosis caused by tumor thrombus protruding from the left portal vein branch. Immediately after stent placement, the stenotic lesion was effectively dilated, the portal blood flow restored, and portal hypertension relieved. Angiography, computed tomography, and doppler ultrasonography done 2 months after the stent placement revealed continued patency of the portal vein. Thus, intraportal placement of an expandable metallic stent appears to be an effective treatment for major portal vein tumor PMID:11252736

Effect of climate change on Alternaria leaf spot of rocket salad and black spot of basil under controlled environment.  

Science.gov (United States)

Plant responses to elevated CO2 and temperature have been much studied in recent years, but effects of climate change on pathological responses are still largely unknown. The pathosystems rocket (Eruca vesicaria subsp. sativa)--Alternaria leaf spot (Alternaria japonica) and basil (Ocimum basilicum)--black spot (Colletotrichum gloeosporioides) were chosen as models to assess the potential impact of increased CO2 and temperature on disease incidence and severity under controlled environment. Potted plants were grown in phytotrons under 4 different simulated climatic conditions: (1) standard temperature (ranging from 18 degrees to 22 degrees C) and standard CO2 concentration (400 ppm); (2) standard temperature and elevated CO2 concentration (800 ppm); (3) elevated temperature (ranging from 22 degrees to 26 degrees C, 4 degrees C higher than standard) and standard CO2 concentration; (4) elevated temperature and CO2 concentration. Each plant was inoculated with a spore suspension containing 1 x 10(5) cfu/ml of the pathogen. Disease incidence and severity were assessed 14 days after inoculation. Increasing CO2 to 800 ppm showed a clear increment in the percentage of Alternaria leaf spot on rocket leaves compared to standard conditions. Basil plants grown at 800 ppm of CO2 showed increased black spot symptoms compared to 400 ppm. Disease incidence and severity were always influenced by the combination of rising CO2 and increased temperature, compared to standard conditions (400 ppm of CO2 - 22 degrees C). Considering the rising concentrations of CO2 and global temperature, we can assume that this could increase the severity of Alternaria japonica on rocket and Colletotrichum gloeosporioides on basil.

The Quantity and Course Of Paraumbilical Veins in Adults, and Their Topographic Relation with the Umbilical Vein (Ligamentum Teres Hepatis  

Directory of Open Access Journals (Sweden)

Full Text Available  Aim : The paraumbilical veins surrounding umbilical vein and running within falciform ligament is of the following three types: Burows veins, Sappeys superior and inferior group veins. Sappey’s veins are referred to as accessory portal veins. They form the connection between portal vein and systemic veins. Burows veins terminate in the middle third of umbilical veins and do not enter the intrahepatic portal system directly. Material and Methods In this study, the falciform ligament specimens from 20 adult cadavers were used to determine the number and course of paraumbilical veins and to expose its topographic relationship with umbilical vein. The falciform ligament separated into four quadrants and examined. Results: Mean numbers of paraumbilical veins were found 6.65 ± 2.1 in microscopical examination. Conclusion: In the relevant literature, there is a lack in studies about the quantity of paraumbilical veins and their topographic relation with the umbilical vein. Detailed information on quantitative parameters of paraumbilical veins may prove helpful in determining pathologies of paraumbilical veins and portalsystemic circulation.

Scientific Electronic Library Online (English)

Full Text Available INTRODUCTION: The main objective of this article is to describe ureterolysis and ovarian vein resection laparoscopic technique. SURGICAL TECHNIQUE: With the patient in a 45o flank position, 3 trocars are used, 1 of 12 mm in the umbilicus for the optic passage, and 2 of 5 and 10 mm inserted in right [...] hypochondrium and iliac fossa, respectively, for the forceps and stapler passage. The ureter and ovarian vein are identified after the mobilization of the colon. Both structures are dissected, with one ovarian vein segment is resected between metallic clips. COMMENTS: the ureteral approach by transperitoneal laparoscopy and colon mobilization facilitates its dissection, identify its relation to other structures, as well as making possible the concomitant treatment of gynecological diseases. For the ovarian syndrome treatment, ureterolysis and ovarian vein resection are performed, using only 3 trocars. Owing to its simplicity, low morbidity, and good results obtained, this procedure represents a good option for the surgical management of this syndrome.

Deep vein thrombosis of the leg  

Energy Technology Data Exchange (ETDEWEB)

Ascending contrast venography is the definitive standard method for the diagnosis of deep vein thrombosis (DVT) of the lower extremities. Authors analysed 22 cases of DVT clinically and radiographically. 1.The patients ranged in age from 15 to 70 yrs and the most prevalent age group was 7th decade (31%). There was an equal distribution of males and females. 2.In 11 cases of 22 cases, variable etiologic factors were recognized, such as abdominal surgery, chronic bedridden state, local trauma on the leg, pregnancy, postpartum, Behcet's syndrome, iliac artery aneurysm, and chronic medication of estrogen. 3.Nineteen cases out of 22 cases showed primary venographic signs of DVT, such as well-defined filling defect in opacified veins and narrowed, irregularly filled venous lumen. In only 3 cases, the diagnosis of DVT was base upon the segmental nonvisualization of deep veins with good opacification of proximal and distal veins and presence of collaterals. 4.Extent of thrombosis: 3 cases were confined to calf vein, 4 cases extended to femoral vein, and 15 cases had involvement above iliac vein. 5.In 17 cases involving relatively long segment of deep veins, propagation pattern of thrombus was evaluated by its radiologic morphology according to the age of thrombus: 9 cases suggested central or antegrade propagation pattern and 8 cases, peripheral or retrograde pattern. 6.None of 22 cases showed clinical evidence of pulmonary embolism. The cause of the rarity of pulmonary embolism in Korean in presumed to be related to the difference in major involving site and propagation pattern of DVT in the leg.

Transvenous liver biopsy via the femoral vein  

International Nuclear Information System (INIS)

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

Subclavian vein thrombosis: A continuing challenge  

International Nuclear Information System (INIS)

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

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)

Cardiac veins: a review of the literature.  

Science.gov (United States)

Cardiac veins have long stood in the shadow of their more extensively studied counterparts, the coronary arteries. The clinical importance of the coronary venous system, nonetheless, should not be underestimated. Intricate and beneficial therapeutic options are increasingly being developed that depend on knowledge of the structure of this venous network. Such interventions have been shown greatly to promote cardiac health, and to enhance the efficacy of cardiac pacing. A comprehensive appreciation of the architecture of the coronary venous system, therefore, is crucial to optimal cardiac care. It is possible to provide an overview of the arrangement of the cardiac veins, with the larger veins draining to the coronary sinus, and thence to the right atrium, but with smaller and minimal veins draining directly to the cavities of the atrial chambers. The venous pathways, nonetheless, are highly variable, making exceptions the commonly accepted rule. As such, unique solutions for imaging, and simple attentiveness to possible venous variations, can greatly enhance clinical outcomes. For example, identifying the diameter, course, and valves of the cardiac veins allows for anticipation of impediments during interventional procedures, and allows for informed clinical decision-making. Also of significance is awareness of alternate arrangements that may be encountered in terms of venous drainage, and the importance of intramural venous collecting spaces in these patterns. The objective of our review, therefore, is to explore and describe the anatomical distribution of the coronary veins. PMID:19097063

Consórcio de manjericão (Ocimum basilicum L.) e alface sob dois arranjos de plantas / Intercrop of basil (Ocimum basilicum L.) and lettuce under two plant arrangements  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Ocimum basilicum L. (Lamiaceae) é comercialmente utilizada como aromatizante ou condimento preparado com suas folhas verdes e aromáticas, que podem ser usadas frescas ou secas. O objetivo deste trabalho foi avaliar a produção de biomassa de manjericão sob duas ou três fileiras no canteiro, consorcia [...] do ou não com alface. O manjericão e a alface foram alocados no campo em experimento conjunto, sendo constituídos cinco tratamentos da seguinte forma: duas fileiras solteiras de manjericão (M2) espaçadas de 0,50 m; três fileiras solteiras de manjericão espaçadas de 0,33 m (M3); quatro fileiras solteiras de alface espaçadas de 0,25 m (A4); duas fileiras solteiras de manjericão consorciadas com quatro fileiras de alface (M2A4) e três fileiras de manjericão consorciada com quatro fileiras de alface (M3A4). O delineamento utilizado foi em blocos casualizados, com oito repetições. As plantas de alface foram colhidas aos 48 dias após o transplantio e as de manjericão, em duas épocas, aos 96 e 113 dias após o transplantio (DAT). O consórcio não influenciou as áreas foliares nem as produções de folhas ou inflorescências do manjericão nem de cabeças comerciais ou não-comerciais da alface. No entanto, quanto ao arranjo de plantas, na segunda época de colheita, as plantas de manjericão cultivadas sob duas fileiras tiveram maior área foliar (2.076,99 cm² planta-1) e maior massa fresca de folhas (5.012,53 kg ha-1). Considerando-se que os valores da Razão de Área Equivalente - RAE na primeira e segunda colheita do manjericão foram maiores que 1,0, conclui-se que o consórcio manjericão com alface é viável. Recomenda-se o arranjo de três fileiras de manjericão alternadas com quatro fileiras de alface, e colheita aos 96 DAT, por ter tido RAE de 2,01. Abstract in english Ocimum basilicum L. (Lamiaceae) is used commercially as flavoring or seasoning that was prepared with its green and aromatic leaves, which can be used fresh or dried. The aim of this work was to evaluate yield of biomass of basil under two or three rows per plot, intercropped or not with lettuce. Ba [...] sil and lettuce were planted at field in joined experiment, which established five treatments: two rows of basil in monocrop system (M2) spaced 0.50 m; three rows of basil in monocrop system spaced 0.33 m (M3); four rows of lettuce in monocrop system spaced 0.25 m (A4); two rows of basil in monocrop system and intercropped with four rows of lettuce (M2A4) and three rows of basil intercropped with four rows of lettuce (M3A4). Used design was randomized blocks with eight replications. Lettuce plants were harvested on 48 days after transplanting and basil plants were harvested in two dates, on 96 and on 113 days after transplanting (DAT). Intercrop did not influence on foliar area neither on yields of leaves of inflorescences of basil neither on commercial or non-commercial lettuce heads. Although, regarding plant arrangement, on second harvest date, basil plants that were cultivated under two rows had the greatest foliar area (2,076.99 cm² plant-1) and the greatest fresh masses of leaves (5,012.53 kg ha-1). Considering that the values of Equivalent Area Ration in the first and the second harvest of basil were higher than 1.0. It was concluded that to intercrop basil with lettuce is viable. It is recommended the arrangement of three rows of basil alternated with four rows of lettuce, with harvested at 96 DAT, because it had EAR of 2.01.

Abnormal formation and communication of external jugular vein  

Directory of Open Access Journals (Sweden)

Full Text Available Knowledge of variations in the origin, course and termination of external jugular vein may be important for surgeons, radiologists, and plastic surgeons. In this report, we present a variation in the origin of the external jugular vein and its abnormal communication with the cephalic vein. The external jugular vein was formed by the union of facial and retromandibular veins. Its course and termination were normal but it communicated with the cephalic vein through a large communicating vein, which crossed superficial to clavicle. The retromandibular vein did not divide into two divisions and the posterior auricular vein was absent. The terminal part of cephalic vein was sandwiched between the clavicle and subclavius muscle.

The structure and function of giraffe jugular vein valves  

OpenAIRE

When a giraffe (Giraffa camelopardalis) lowers its head to drink, blood could enter the jugular vein from the inferior vena cava or regurgitate from the jugular veins into the cranial veins. We investigated the anatomy of jugular valves in giraffes to establish if they could prevent either of these regurgitations. Jugular vein length and intervalve distances of 396 valves (192 left, 204 right) were measured in 60 veins from 25 adult (11 males and 14 females) and five foetal giraffes. The aver...

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

Type II (13.3%), the CVA originates at the median cubital vein (MCuV), which anastomoses to the BVF. Type III (20%), there is no communication between BVF and CVF at the cubital fossa. Type IV (8.3%), CVF drains into the BVF. Type V (11.7%) - Other disposition, which include the "M" classical, resulting from the division of the median antebrachial vein. Using the MCV or CVF, is recommended, since there are risks of puncture of other important anatomical structures such as the anterior branch of the medial antebrachial cutaneous nerve.

Bilateral parotid-duct diversion using autologous vein grafts for the management of chronic drooling in cerebral palsy.  

Science.gov (United States)

Chronic drooling is a major problem in patients with cerebral palsy and other neurological dysfunctions. Various treatments, ranging from speech therapy to radical surgery, have been used to overcome this distressing problem, with surgery the most consistently successful. In this study, we used a new surgical technique to manage severe drooling. This involved the dissection of both parotid-duct orifices, and their relocation, via a submucosal tunnel, into the tonsillar pillar using autologous vein grafts. Four patients were treated using this technique together with bilateral submandibular duct rerouting. The results were analysed by subjective judgements of drooling and retrograde sialography at 90 days postoperatively. In all cases, salivary flow was reduced and drooling was significantly improved. Retrograde sialography revealed no signs of obstruction or stricture formation in any of the cases. No postoperative complications occurred. These preliminary results suggest that the bilateral surgical transposition of Stensen's ducts into the tonsillar pillar using autologous vein grafts together with bilateral submandibular duct rerouting can provide effective control of chronic drooling.

Effect of cultivar on phenolic levels, anthocyanin composition, and antioxidant properties in purple basil (Ocimum basilicum L.).  

Science.gov (United States)

In this study, we determined the effect of cultivar on total and individual anthocyanin concentrations and phenolic acid levels in eight purple basil varieties and examined the relationship between anthocyanin content, phenolic acid composition, and antioxidant properties. Cultivar had a significant influence on total anthocyanin concentrations as well as individual anthocyanin composition. The four major basil anthocyanins (labelled A-D) were quantified and cultivar had a statistically significant effect on anthocyanins B (p<0.01), C (p<0.01), and D (p<0.01), but not on anthocyanin A (p=0.94). Cultivar did not have a significant effect on total phenolic levels, although it did influence the concentration of some individual phenolic acids, including caftaric (p=0.03) and chicoric (p=0.04) acids. Although total phenolic and anthocyanin levels correlated with measured FRAP antioxidant capacities, for some cultivars the individual phenolic acid and anthocyanin composition was also an important factor affecting the antioxidant properties.

Cubital tunnel syndrome: Simple decompression versus decompression and anterior subcutaneous transposition  

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english BACKGROUND: The procedure of choice in the surgical treatment of cubital tunnel syndrome remains controversial. The aim of this study is to report the results of simple decompression and decompression with anterior subcutaneous transposition. METHODS: A retrospective review (July 2002-January 2007) [...] using the Bishop Score to assess outcome. A total of 102 procedures (91 patients, 11 bilateral) were performed with a minimum of 9 months' post-operative follow-up. The procedure was selected intra-operatively. All cases were operated by the senior author (MC). RESULTS: In the simple decompression group (n=47, average age 45.9 years), the average Bishop Score was 11.3 (5-13) with an average time to recovery of 3.7 months (1-6). Good to excellent results were obtained in 94% and fair results in 6%. In the anterior transposition group (n=55, average age 43.3 years) the average Bishop Score was 10.6 (5-13) with average time to recovery of 4.2 months (1-6). Good to excellent results were obtained in 93% and fair results in 7%. Complications included subluxation of the ulnar nerve in two cases, one wound dehiscence and one post-operative haematoma. CONCLUSIONS: The outcome in both groups was the same. Recovery is often prolonged. It took 3-6 months for 69% of patients to recover. Younger patients recovered sooner and the transposition and elderly groups took longer to recover. Simple decompression is adequate unless the nerve is unstable or the bed unsuitable.

Demonstration of IS711 transposition in Brucella ovis and Brucella pinnipedialis  

Directory of Open Access Journals (Sweden)

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

Characterization of two candidate flavone 8-O-methyltransferases suggests the existence of two potential routes to nevadensin in sweet basil.  

Science.gov (United States)

Regioselective 6-,7-,8-,3'-, and 4'-O-methylations underlie the structural diversity of lipophilic flavones produced in the trichomes of sweet basil (Ocimum basilicum L.). The positions 6, 7, and 4' are methylated by a recently described set of cation-independent enzymes. The roles of cation-dependent O-methyltransferases still require elucidation. Here, the basil trichome EST database was used to identify a Mg(2+)-dependent O-methyltransferase that was likely to accept flavonoids as substrates. The recombinant protein was found to be active with a wide range of o-diphenols, and methylated the 8-OH moiety of the flavone backbone with higher catalytic efficiency than the 3'-OH group of candidate substrates. To further investigate flavone 8-O-methylation, the activity of a putative cation-independent flavonoid 8-O-methyltransferase from the same EST collection was assessed with available substrate analogs. Notably, it was strongly inhibited by gardenin B, one of its expected products. The catalytic capacities of the two studied proteins suggest that two alternative routes to nevadensin, a major flavone in some basil cultivars, might exist. Correlating the expression of the underlying genes with the accumulation of 8-substituted flavones in four basil lines did not clarify which is the major operating pathway in vivo, yet the combined data suggested that the biochemical properties of flavone 7-O-demethylase could play a key role in determining the reaction order.

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.

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.

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

International Nuclear Information System (INIS)

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

M-Ary Substitution/Deletion/Insertion/Adjacent-Symbol-Transposition Error Correcting Codes for Data Entry Systems  

Science.gov (United States)

Nonbinary M-ary data processed by data entry systems, such as keyboard devices and character recognition systems, often have various types of error, such as symbol-substitution errors, deletion errors, insertion errors, and adjacent-symbol-transposition errors. This paper proposes nonsystematic M-ary codes capable of correcting these errors. The code is defined as a set of codewords that satisfy three conditions required to correct substitution, deletion/insertion, and adjacent-symbol-transposition errors. Since symbol-substitution errors in data entry systems are usually asymmetric, this paper also presents asymmetric-symbol-substitution error correcting codes capable of correcting deletion, insertion, and adjacent-symbol-transposition errors. For asymmetric-symbol-substitution error correction, we employ a mapping derived from the vertex coloring in an error directionality graph. The evaluation shows that the asymmetric codes have three to five times larger number of codewords than the symmetric codes.

Finger Vein Recognition Using Haar Wavelet Transform?  

Directory of Open Access Journals (Sweden)

Full Text Available Finger vein is an important biometric technique for personal identification and authentication. The finger vein is a blood vassal network under the finger skin. The network pattern is distinct for each individual, unaffected by aging and it is internal. i.e. inside human skin which can always guarantee more security authentication. finger?vein recognition systems capture images by using near infrared (NIR illumination in conjunction with a camera. However, such systems can face operational difficulties, since the scattering of light from the skin can make capturing a clear image difficult, which represent the major challenge in our proposed system, which is how to localize the vein grid, and the following challenges are choosing the suitable feature vector to identify the vein pattern. The attracting features of the Haar Wavelet Transform, including fast for implementation and able to analyse the local feature makes it the suitable choice in our system. The system was tested over a database collected from 106 volunteers, where 6 images are collected for each person. The attained identification result is encouraging where equal error rate for one level decomposed wavelet was (98.7%, and when increasing the levels of decomposed wavelet was (99.8%.

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

Identification of a unique 2-oxoglutarate-dependent flavone 7-O-demethylase completes the elucidation of the lipophilic flavone network in basil.  

Science.gov (United States)

Small molecule demethylation is considered unusual in plants. Of the studied instances, the N-demethylation of nicotine is catalyzed by a Cyt P450 monooxygenase, while the O-dealkylation of alkaloids in Papaver somniferum is mediated by 2-oxoglutarate-dependent dioxygenases (2-ODDs). This report describes a 2-ODD regiospecifically catalyzing the 7-O-demethylation of methoxylated flavones in peltate trichomes of sweet basil (Ocimum basilicum L.). Three candidate 2-ODDs were identified in the basil trichome transcriptome database. Only the candidate designated ObF7ODM1 was found to be active with and highly specific for the proposed natural substrates, gardenin B and 8-hydroxysalvigenin. Of the characterized 2-ODDs, ObF7ODM1 is most closely related to O-demethylases from Papaver. The demethylase activity in trichomes from four basil chemotypes matches well with the abundance of ObF7ODM1 peptides and transcripts in the same trichome preparations. Treatment of basil plants with a 2-ODD inhibitor prohexadione-calcium significantly reduced the accumulation of 7-O-demethylated flavone nevadensin, confirming the involvement of a 2-ODD in its formation. Notably, the full-length open reading frame of ObF7ODM1 contains a second in-frame AUG codon 57 nucleotides downstream of the first translation initiation codon. Both AUG codons are recognized by bacterial translation machinery during heterologous gene expression. The N-truncated ObF7ODM1 is nearly inactive. The N-terminus essential for activity is unique to ObF7ODM1 and does not align with the sequences of other 2-ODDs. Further studies will reveal whether alternative translation initiation plays a role in regulating the O-demethylase activity in planta. Molecular identification of the flavone 7-O-demethylase completes the biochemical elucidation of the lipophilic flavone network in basil. PMID:25378691

d-Transposition of the great arteries in a 12-year-old child: is arterial switch still an option?  

Science.gov (United States)

Arterial switch surgery for d-transposition of great arteries is usually performed in the first 2 weeks of life before the left ventricle regresses. The arterial switch surgery that helps achieve anatomic and physiologic correction of this condition has better long-term outcomes than other surgical approaches. The procedure may still be attempted at an older age where the left ventricle has not regressed. We report a rare case of a 12-year-old child with d-transposition of great arteries, a remote muscular ventricular septal defect and isolated valvar pulmonic stenosis, which was corrected by an arterial switch surgery.

Management of proximal deep vein thrombosis.  

Science.gov (United States)

Iliofemoral DVT constitutes approximately 20-25% of lower limb DVT and represents a specific subgroup of patients at highest risk for post-thrombotic syndrome (PTS). Anticoagulation alone has no significant thrombolytic activity and has not impact on PTS prevention. Early thrombus removal has reduced PTS in uncontrolled reports and reviews but major trials are awaited. The optimal timing for treatment appear to be thrombus IVC filter deployment to reduce periprocedural PE, is supported by little evidence unless an indication for its use already exists. However, balloon venoplasty and vein stents undoubtedly vein patency after treatment. Early thrombus removal comes with additional upfront costs derived from devices, imaging and critical care bed usage. However, significant potential savings from reduction in PTS and rethrombosis rates may reduce overall societal costs. This review focuses on iliofemoral thrombosis, however, the less commonly encountered but clinically important subclavian vein thrombosis is also discussed. PMID:22457306

Phasic contractions of the dorsal foot veins were detected in 7 male subjects, aged 23 to 49 years, by means of a linear variable differential transformer (LVDT) after congesting the veins by a pressure of 6.7 kPa (50 torr). This phasic activity (PA) had a frequency of 3 to 7 contractions per minute and led to a periodic diminution of the diameter of the distended veins by 12 to 44%. Using a double LVDT, the PA was shown to represent peristaltic waves travelling along the vessel wall concomitantly with the venous return. Determined in 3 out of the 7 subjects, the velocity of the waves amounted to 3.6 to 6.1 mm per second. A rheological significance of the peristaltic waves is assumed. PMID:3178793

Finger Vein Recognition System Using Image Processing  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract- With increase in globalization and standard of living, there has been a steady increase in the use and development of consumer electronics. This calls for the need of convenient, simple, high security authentication systems to protect personal information stored in mobile devices. With increasing emphasis on security and high complexity of existing biometric systems in time or space or both, automated personal identification using finger-vein biometric is becoming a very active topic in both research and practical applications. In this paper, we have described and implemented an algorithm for finger-vein recognition system using image processing.

Deep vein thrombosis: a clinical review  

Directory of Open Access Journals (Sweden)

Full Text Available Emeka Kesieme1, Chinenye Kesieme2, Nze Jebbin3, Eshiobo Irekpita1, Andrew Dongo11Department of Surgery, Irrua Specialist Teaching Hospital, Irrua, Nigeria; 2Department of Paediatrics, Irrua Specialist Teaching Hospital, Irrua, Nigeria; 3Department of Surgery, University of Port Harcourt Teaching Hospital, Port-Harcourt, NigeriaBackground: Deep vein thrombosis (DVT is the formation of blood clots (thrombi in the deep veins. 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

Bombyx mori Nucleopolyhedrovirus Bacmid Enabling Rapid Generation of Recombinant Virus by In Vitro Transposition.  

Science.gov (United States)

A novel recombinant bacmid, bEasyBm, that enables the easy and fast generation of pure recombinant baculovirus without any purification step was constructed. In bEasyBm, attR recombination sites were introduced to facilitate the generation of a recombinant viral genome by in vitro transposition. Moreover, the extracellular RNase gene from Bacillus amyloliquefaciens, barnase, was expressed under the control of the Cotesia plutellae bracovirus early promoter to negatively select against the nonrecombinant background. The bEasyBm bacmid could only replicate in host insect cells when the barnase gene was replaced with the gene of interest by in vitro transposition. When bEasyBm was transposed with pDualBac-EGFP, the resulting recombinant virus, EasyBm-EGFP, showed high levels of EGFP expression efficiency compared with that of non-purified recombinant virus BmGOZA-EGFP, which was constructed using the bBmGOZA system. In addition, nonrecombinant backgrounds were not detected in unpurified EasyBm-EGFP stocks. Based on these results, a high-throughput system for the generation of multiple recombinant viruses at a time was established. PMID:25341472

A comparative study of Tam3 and Ac transposition in transgenic tobacco and petunia plants.  

Science.gov (United States)

Transposition of the Anthirrinum majus Tam3 element and the Zea mays Ac element has been monitored in petunia and tobacco plants. Plant vectors were constructed with the transposable elements cloned into the leader sequence of a marker gene. Agrobacterium tumefaciens-mediated leaf disc transformation was used to introduce the transposable element constructs into plant cells. In transgenic plants, excision of the transposable element restores gene expression and results in a clearly distinguishable phenotype. Based on restored expression of the hygromycin phosphotransferase II (HPTII) gene, we established that Tam3 excises in 30% of the transformed petunia plants and in 60% of the transformed tobacco plants. Ac excises from the HPTII gene with comparable frequencies (30%) in both plant species. When the beta-glucuronidase (GUS) gene was used to detect transposition of Tam3, a significantly lower excision frequency (13%) was found in both plant species. It could be shown that deletion of parts of the transposable elements Tam3 and Ac, removing either one of the terminal inverted repeats (TIR) or part of the presumptive transposase coding region, abolished the excision from the marker genes. This demonstrates that excision of the transposable element Tam3 in heterologous plant species, as documented for the autonomous element Ac, also depends on both properties. Southern blot hybridization shows the expected excision pattern and the reintegration of Tam3 and Ac elements into the genome of tobacco plants. PMID:2562396

Oversized vein grafts develop advanced atherosclerosis in hypercholesterolemic minipigs  

DEFF Research Database (Denmark)

ABSTRACT: BACKGROUND: Accelerated atherosclerosis is the main cause of late aortocoronary vein graft failure. We aimed to develop a large animal model for the study of pathogenesis and treatment of vein graft atherosclerosis. METHODS: An autologous reversed jugular vein graft was inserted end-to-end into the transected common carotid artery of ten hypercholesteroemic minipigs. The vein grafts were investigated 12-14 weeks later with ultrasound and angiograpy in vivo and microscopy post mortem. RESULTS: One minipig died during follow up (patent vein graft at autopsy), and one vein graft thrombosed early. In the remaining eight patent vein grafts, the mean (standard deviation) intima-media thickness was 712 mum (276 mum) versus 204 mum (74 mum) in the contralateral control internal jugular veins (P diameter of artery). No plaques were found in four non-oversized vein grafts (P <.05). CONCLUSIONS: Our model of jugular vein graft in the common carotid artery of hypercholesterolemic minipigs displayed the components of human vein graft disease, i.e. thrombosis, intimal hyperplasia, and atherosclerosis. Advanced atherosclerosis, the main cause of late failure of human aortocoronary vein grafts was only seen in oversized grafts. This finding suggests that oversized vein grafts may have detrimental effects on patient outcome.

Crossectomy and great saphenous vein stripping.  

Science.gov (United States)

Crossectomy and stripping have been the standard of care for primary great saphenous varicose veins since the high failure rates of sclerotherapy became apparent in the 1970s. As the specialty of venous surgery has evolved, a number of clinical trials have established the optimal methods of surgical treatment, and the clinical benefit of routine stripping. Long-term trials, however, have uncovered a high recurrence rate after varicose vein surgery that approaches 70% after 10 years. There is much debate about whether this is the result of the dilatation of existing tributaries in the groin or the growth of new veins as a result of angiogenesis that follows surgical treatment and healing (neovascularisation). The addition of barrier technology to current crossectomy has the potential to improve the results of surgery in the future. In the meanwhile, new techniques are evolving to obliterate the great saphenous vein, including endovenous laser, radiofrequency ablation and foam sclerotherapy. Randomised clinical trials are urgently required to compare these new treatments against standard surgery, and they will need to focus on whether the short-term gains in reduced convalescence and morbidity are balanced by durable long-term results.

Complete transposition of the aorta and pulmonary artery in a Belgian Blue crossbreed calf: A case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Complete transposition of the great arteries is a congenital cardiac malformation occasionally encountered in cattle and other species. The objective of the present report was to provide a detailed clinical, echocardiographic and post mortem description of a calf presenting with this condition. Case presentation A 6-week old male Belgian Blue cross-breed calf was examined for respiratory distress and exercise intolerance. The patient was bright, alert and responsive without any neurologic abnormalities but was exercise intolerant, had marked cyanosis, tachycardia, tachypnea, a pansystolic heart murmur as well as a bilaterally palpable thrill over the heart. Arterial blood gas analysis revealed marked hypoxemia (PaO2 = 23 mmHg, O2sat = 41.1%, mild hypercapnia and compensated respiratory acidosis. Echocardiographic examination revealed a complete transposition of the great arteries in combination with a ventricular septal defect through which blood shunted bidirectionally. Cardiac catheterization confirmed that arterialization of blood of the systemic circulation solely occurred in the right ventricle through blood shunting from the left into the right ventricle. Results of post mortem examination are presented. Conclusion Complete transposition of the great arteries is a cyanotic congenital anomaly repeatedly reported in calves that should be considered as differential diagnosis in patients presenting with hypoxemia more severe than commonly encountered with other congenital cyanotic heart conditions. We give a comprehensive summary of the clinical presentation, diagnostic work-up and post mortem examination of a Belgian Blue cross-breed calf with complete transposition of the great arteries

Inferior Alveolar Nerve Lateralization and Transposition for Dental Implant Placement. Part I: a Systematic Review of Surgical Techniques  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: The purpose of this first part of a two-part series was to review the literature concerning the indications, contraindications, advantages, disadvantages and surgical techniques of the lateralization and transposition of the inferior alveolar nerve, followed by the placement of an implant in an edentulous atrophic posterior mandible. Material and Methods: A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed and PMC database, academic sites and books. The articles were searched from January 1997 to July 2014 and comprised English-language articles that included adult patients between 18 and 80 years old with minimal residual bone above the mandibular canal who had undergone inferior alveolar nerve (IAN repositioning with a minimum 6 months of follow-up. Results: A total of 16 studies were included in this review. Nine were related to IAN transposition, 4 to IAN lateralization and 3 to both transposition and lateralization. Implant treatment results and complications were presented. Conclusions: Inferior alveolar nerve lateralization and transposition in combination with the installation of dental implants is sometimes the only possible procedure to help patients to obtain a fixed prosthesis, in edentulous atrophic posterior mandibles. With careful pre-operative surgical and prosthetic planning, imaging, and extremely precise surgical technique, this procedure can be successfully used for implant placement in edentulous posterior mandibular segments.

Influence of Zn foliar application on growth characteristics and essential oil yield of basil (Ocimum basilicum L. under salinity stress  

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

Evaluation of left renal vein entrapment using multidetector computed tomography  

Energy Technology Data Exchange (ETDEWEB)

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 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.

Endoscopic saphenous vein harvesting: minimally invasive video-assisted saphenectomy.  

Science.gov (United States)

A technique of greater saphenous vein harvesting for coronary artery revascularization using an endoscopic approach is herein detailed. The saphenous vein is directly identified at the knee through a single incision. An endoscopic dissector is advanced proximally and distally along the course of the vein, ligating side-branches with clips. The vein is divided at the ends of dissection, dependent on patient anatomy, by either a counterincision, endoscopic clips, or ligation with an Endo-loop. PMID:9354558

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.

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

MR venography of the inferior mesentery vein  

Energy Technology Data Exchange (ETDEWEB)

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 insertion of the IMV is into the splenic vein. A minority of patients with cirrhosis had dilatation of the IMV.

Isolated thrombosis of the external jugular vein.  

Science.gov (United States)

Thrombosis of the external jugular vein (EJV) is an infrequent clinical condition that has been associated with central venous catheterization, head and neck infections, intravenous drug abuse, and compression at the affected site. The authors report a case of thrombotic obstruction of the EJV in the late postoperative period after laparoscopic anterior lumbar interbody fusion. A 40-year-old morbidly obese woman with a depressive syndrome was diagnosed with L5-S1 discopathy and was submitted to laparoscopic anterior isthmic fusion. The operation lasted approximately 6 hours, during which the patient remained in a supine decubitus and Trendelenburg position. The left radial artery, peripheral veins, and right internal jugular vein were canalized. The internal jugular vein catheter was electively withdrawn 24 hours after the intervention. The postoperative period was satisfactory, and the patient was started on prophylaxis with low-molecular-weight heparin. She sat up and began walking at 24 hours and was discharged to her home 4 days after the procedure. Eight days after discharge she returned, experiencing right cervical pain. Palpation revealed a painful induration and erythematous area under the anterior edge of the sternocleidomastoid muscle. Results of otoscopy and laryngoscopy were normal. Cervical echo-Doppler disclosed an image consistent with EJV thrombosis. The most frequent causes of jugular vein thrombosis are mentioned above. A higher incidence has been described after upper abdomen and pelvic surgery; other contributing factors are age, obesity, and associated illness. There are few references in the literature to position-induced EJV thrombosis in the late postoperative period. The authors' patient presented signs and symptoms of EJV thrombosis (probably because of various factors), which was confirmed by echo-Doppler study and treated with 10 days of calcic heparin.

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

These findings agree with previous papers describing a prevalence of 60% of posterior gastric vein in patients submitted to surgery in portal hypertension, and in all cases, this vein was tributary of the splenic vein. The identification of this vein may influence the treatment, because if left untied during cases of portal-azigos disconnection, they may predispose to postoperative bleeding, but in cases of splenorenal anastomosis may preserve its patency in cases of anastomosis occlusion, or can lead again to postoperative bleeding feeding the esophageal varices. To ligate or not this vein will depends on the surgeon 's experience and common sense. Regarding to previous papers and to this data presented here, the authors believe that the prevalence of this vein is between 50 and 60% in the population.

Inferior vena cava hypoplasia with right hepatic vein and accessory inferior hepatic vein shunt.  

Science.gov (United States)

Inferior vena cava (IVC) hypoplasia is a rare condition. Venous blood flow is usually provided through collaterals in the azygos or hemiazygos venous systems. However, portosystemic shunts with intrahepatic venous collateral are extremely rare. The case is presented here of a large shunt between the right hepatic vein, accessory inferior hepatic vein, and inferior vena cava in a 37-year-old female patient with IVC hypoplasia. PMID:24590531

Science.gov (United States)

The performance of funicular lymphography and spermatic vein phlebography during orchiectomy in patients with testicular tumors demonstrates the close proximity of the spermatic vein to the lymph nodes draining the testicles. In the case of metastatic lymph node involvement the spermatic vein phlebography may add supplementary diagnostic information. The examination was proved successful in eight patients with malignant testicular tumors. PMID:904745

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese CONTEXTO: Traumatismos ou tromboses que possam evoluir com alterações da drenagem venosa do membro superior, dependendo do território interrompido, podem ter como mecanismo compensatório uma via colateral de drenagem sem que haja prejuízo para o retorno venoso desse membro. 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.

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.

Primary varicose veins: Frequency, clinical significance and surgical treatment  

Directory of Open Access Journals (Sweden)

Full Text Available INTRODUCTION According to the definition of the World Health Organization, varicose veins represent abnormally enlarged superficial veins having baggy or cylindrical shape. The most frequent cause of primary varicose veins is the insufficiency of long saphenous vein (LSV, but especially the basin of its connection with femoral vein and perforating veins. OBJECTIVE The objectives of these investigations were: the determination of insufficiency incidence of SSV in cases of LSV insufficiency; the establishment of association of insufficiency of perforating veins of the basin of LSV and SSV; the study of the results of surgical treatment of insufficiency and varicosity of both short and long saphenous veins. METHODS In this study, 100 patients (66 women and 34 men, average age 52.1 years, with clinical symptoms showing the insufficiency and varicosity of long saphenous vein with no change of deep vein system were examined. Ultrasonographic examinations were made using Color Doppler probes - 7.5 and 3.75 MHz (Toshiba Corevison SSA 350 A; the development of incompetence of long saphenous vein (LSV and short saphenous vein (SSV at the level of the junction as well as other incompetent valves were examined. The reflux was defined as a retrograde flow of the duration longer than 0.5 seconds. RESULTS The insufficiency of short saphenous vein was determined by ultrasonographic examination in 34%, while the insufficiency of perforating veins in 80% of patients. 40% of patients were operated (33.3% of females, and 52.9% of males. The most frequent indications for surgical treatment of superficial veins insufficiency were: strong varicosities, clear symptoms and signs, superficial thrombophlebitis and conditions after superficial thrombophlebitis. Surgical treatment was applied in 16% of patients due to recurrence in the basin of long saphenous vein, and in 6% of cases because of the recurrence in the basin of short saphenous vein. Data analysis failed to discover any statistically significant difference between the age of patients and varicosities in the basin of long saphenous vein as well as in the basin of short saphenous vein (51.98±9.97 years; 54.50±31.82 years; t=0.36; p>0.05, or any significant difference of BMI value, with regard to the obesity of patients and varicosities in the basin of long saphenous vein as well as in the basin of short saphenous vein (28.02±4.61 kg/m2; 24.50±6.36 kg/m2; t=0.50; p>0.05. No statistically significant correlation was found between Color Duplex findings of insufficiency of both long saphenous vein and short saphenous vein (p=-0.21 ; p>0.05, nor any significant correlation of Color Duplex findings of perforating veins insufficiency in the basin of long saphenous vein and short saphenous vein (p=-0.115; p>0.05. CONCLUSION The incidence of insufficiency is significant: approximately every third patient has short saphenous vein insufficiency, while three third of patients have perforating veins insufficiency. Color Duplex limb's veins ultrasonography is highly reliable method for the examination and study of superficial veins diseases, which is very important for preoperative decision-making and selection of surgical technique as well as for postoperative follow-up.

MDCT Venography Evaluation of a Rare Collateral Vein Draining from the Left Subclavian Vein to the Great Cardiac Vein  

Science.gov (United States)

Congenital vascular anomalies of the venous drainage in the chest affect both cardiac and non-cardiac structures. Collateral venous drainage from the left subclavian vein to the great cardiac vein is a rare venous drainage pattern. These anomalies present a diagnostic challenge. Multi-detector computed tomography (MDCT) is useful in the diagnosis and treatment planning of these clinically complex disorders. We present a case report of an 18-year-old Caucasian male who came to our institute for evaluation of venous drainage patterns to the heart. We describe the contrast technique of bilateral dual injection MDCT venography and the imaging features of the venous drainage patterns to the heart. PMID:25379351

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.

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.

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.

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.

Biometric Authentication Using Infrared Imaging of Hand Vein Patterns  

Science.gov (United States)

Hand vein patterns are unique and universal. Vein pattern is used as biometric feature in recent years. But, it is not very much popular biometric system as compared to other systems like fingerprint, iris etc, because of the higher cost. For conventional algorithm, it is necessary to use high quality images, which demand high-priced collection devices. There are two approaches for vein authentication, these are hand dorsa and hand ventral. Currently we are working on hand dorsa vein patterns. Here we are putting forward the new approach for low cost hand dorsa vein pattern acquisition using low cost device and proposing a algorithm to extract features from these low quality images.

Transposable elements reveal the impact of introgression, rather than transposition, in Pisum diversity, evolution, and domestication.  

Science.gov (United States)

The genetic structure and evolutionary history of the genus Pisum were studied exploiting our germplasm collection to compare the contribution of different mechanisms to the generation of diversity. We used sequence-specific amplification polymorphism (SSAP) markers to assess insertion site polymorphism generated by a representative of each of the two major groups of LTR-containing retrotransposons, PDR1 (Ty1/copia-like) and Cyclops (Ty3/gypsy-like), together with Pis1, a member of the En/Spm transposon superfamily. The analysis of extended sets of the four main Pisum species, P. fulvum, P. elatius, P. abyssinicum, and P. sativum, together with the reference set, revealed a distinct pattern of the NJ (Neighbor-Joining) tree for each basic lineage, which reflects the different evolutionary history of each species. The SSAP markers showed that Pisum is exceptionally polymorphic for an inbreeding species. The patterns of phylogenetic relationships deduced from different transposable elements were in general agreement. The retrotransposon-derived markers gave a clearer separation of the main lineages than the Pis1 markers and were able to distinguish the truly wild form of P. elatius from the antecedents of P. sativum. There were more species-specific and unique PDR1 markers than Pis1 markers in P. fulvum and P. elatius, pointing to PDR1 activity during speciation and diversification, but the proportion of these markers is low. The overall genetic diversity of Pisum and the extreme polymorphism in all species, except P. abyssinicum, indicate a high contribution of recombination between multiple ancestral lineages compared to transposition within lineages. The two independently domesticated pea species, P. abyssinicum and P. sativum, arose in contrasting ways from the common processes of hybridization, introgression, and selection without associated transpositional activity.

Atypical penile Mondor's disease - involvement of the circumflex vein.  

Science.gov (United States)

Mondor's disease is a rare condition characterised by superficial thrombophlebitis of subcutaneous veins, most commonly over the anterior chest wall. Penile Mondor's disease is rarer, arising out of thrombophlebitis of the penile veins. It typically involves the dorsal vein of the penis and presents with a cord-like indurated lesion with a beaded feel, palpable along the length of the involved vein. Though penile Mondor's disease involving the dorsal vein of the penis has been reported by many authors, we report a peculiar case of penile Mondor's disease in a 26-year-old sexually active man with thrombophlebitis of the circumflex vein of the penis with sparing of the dorsal vein. Diagnosis was confirmed on Doppler ultrasonography of the penile venous system. Despite exhaustive history taking, no cause could be elicited. The lesion completely subsided within three days with daily local hot fomentation. We propose the term 'atypical penile Mondor's disease' for such a case. PMID:24867818

A Shigella sonnei outbreak traced to imported basil--the importance of good typing tools and produce traceability systems, Norway, 2011.  

Science.gov (United States)

On 9 October 2011, the University Hospital of North Norway alerted the Norwegian Institute of Public Health (NIPH) about an increase in Shigella sonnei infections in Tromsø. The isolates had an identical ‘multilocus variable-number tandem repeat analysis’ (MLVA) profile. Most cases had consumed food provided by delicatessen X. On 14 October, new S. sonnei cases with the same MLVA-profile were reported from Sarpsborg, south-eastern Norway. An outbreak investigation was started to identify the source and prevent further cases. All laboratory-confirmed cases from both clusters were attempted to be interviewed. In addition, a cohort study was performed among the attendees of a banquet in Tromsø where food from delicatessen X had been served and where some people had reported being ill. A trace-back investigation was initiated. In total, 46 cases were confirmed (Tromsø= 42; Sarpsborg= 4). Having eaten basil pesto sauce or fish soup at the banquet in Tromsø were independent risk factors for disease. Basil pesto was the only common food item that had been consumed by confirmed cases occurring in Tromsø and Sarpsborg. The basil had been imported and delivered to both municipalities by the same supplier. No basil from the specific batch was left on the Norwegian market when it was identified as the likely source. As a result of the multidisciplinary investigation, which helped to identify the source, the Norwegian Food Safety Authority, together with NIPH, planned to develop recommendations for food providers on how to handle fresh plant produce prior to consumption.

Lepromatous phlebitis of the external jugular vein.  

Science.gov (United States)

Mycobacterium leprae (M leprae), the causative agent of Hansen's disease, is endemic in many areas of Asia, sub-Saharan Africa, South and Central America, the Pacific Islands, and the Philippines. The spectrum of clinical disease is dependent on the patient's cell-mediated immunity and might range from localized anesthetic patches or plaques to disseminated disease. If undiagnosed, progression with damage to the involved sensory and motor nerves might occur. Lepromatous vasculitis occurs most commonly in patients with severe disseminated disease. Vascular disease, as the initial presenting sign of tuberculoid leprosy, is, however, rare. We present one patient in whom the development of Hansen's disease was associated with involvement of the external jugular vein and was initially seen as external jugular vein fibrosis.

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 diagnosis of portal vein thrombosis  

Energy Technology Data Exchange (ETDEWEB)

Contrast-enhanced and non-enhanced computed tomographic (CT) features were reviewed of 168 patients with an established diagnosis of portal vein thrombosis. CT values of both neoplastic thrombi (NT) and organized, non-neoplastic thrombi (non-NT) were similar to those of blood on non-enhanced CT. The values for NT increased from 15 H.U. on non-enhanced CT to 41 H.U. on enhanced CT, enabling the discrimination between NT and non-NT. Non-enhanced CT depicted high density areas indicative of recent blood clots at the tip of NT in 5 patients with advanced hepatocellular carcinoma. It also showed portal vein thrombus or wall calcifications in each of two non-NT patients. Unlike in one patient with associated fatty liver showing intrahepatic segmental or lober hyperdensity on non-enhanced CT, it was hypodense in 29 patients with hepatocellular or metastatic carcinoma. When NT extended into the portal trunk, tumor-bearing region was also shown as hypodensity. Enhanced CT features of segmental or lober hypodensity in the 29 patients were classified as greater than the parenchyma (n = 10) and equal to it (n = 19). This discrepancy seems to have resulted from increased arterial blood flow, as well as from increased interstitial space due to fibrosis. Among 18 patients with NT of the peripheral portal vein that was missed on enhanced CT, six had segmental hypodensity on non-enhanced CT. This suggests the potential of non-enhanced CT in the diagnosis of peripheral portal vein obstruction. (Namekawa, K.).

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.

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.

Metabolic effects of portal vein sensing.  

Science.gov (United States)

The extrinsic gastrointestinal nerves are crucial in the sensing of nutrients and hormones and its translation in terms of control of food intake. Major macronutrients like glucose and protein are sensed by the extrinsic nerves located in the portal vein walls, which signal to the brain and account for the satiety phenomenon they promote. Glucose is sensed in the portal vein by neurons expressing the glucose receptor SGLT3, which activate the main regions of the brain involved in the control of food intake. Proteins indirectly act on food intake by inducing intestinal gluconeogenesis and its sensing by the portal glucose sensor. The mechanism involves a prior antagonism by peptides of the ?-opioid receptors present in the portal vein nervous system and a reflex arc with the brain inducing intestinal gluconeogenesis. In a comparable manner, short-chain fatty acids produced from soluble fibre act via intestinal gluconeogenesis to exert anti-obesity and anti-diabetic effects. In the case of propionate, the mechanism involves a prior activation of the free fatty acid receptor FFAR3 present in the portal nerves and a reflex arc initiating intestinal gluconeogenesis.

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.

The upper group of hepatic veins consists of three veins which extend to the posterior face of the liver to join the inferior cava. The left renal vein passes anterior to the aorta just below the origin of the superior mesenteric artery. We detected a variation in the hepatic and renal veins in a multislice CT angiogram of a nine-year-old male patient in the Radiology Department of Afyon Kocatepe University Medical School. The upper group hepatic veins normally drains into the inferior vena cava as three separate trunks, namely the right, left and middle. In our case, we found that only the right and left hepatic veins existed and the middle hepatic vein was absent. Furthermore, the left renal vein, which normally passes anterior to the abdominal aorta, was retro-aortic. Left renal vein variations are of great importance in planning retroperitoneal surgery and vascular interventions. Knowledge of a patient’s hepatic vein and renovascular anatomy and determining their variations and anomalies are of critical importance to abdominal operations, transplantations and preoperative evaluation of endovascular interventions.

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.

What actually happens to EU directives in the member states?: A cross-country cross-sector view on national transposition instruments  

OpenAIRE

This study empirically investigates the transposition patterns of EU directives in all 15 member states and in six major sectors of the economy with a view on analysing the political-economic reasons behind sector and national differences in the legal transposition instruments used. In particular, we model the influence of both national sector importance and governmental constellations on the ratio of primary to totally transposed EU directives. We find that government strength and net EU rec...

IS1397 Is Active for Transposition into the Chromosome of Escherichia coli K-12 and Inserts Specifically into Palindromic Units of Bacterial Interspersed Mosaic Elements  

OpenAIRE

We demonstrate that IS1397, a putative mobile genetic element discovered in natural isolates of Escherichia coli, is active for transposition into the chromosome of E. coli K-12 and inserts specifically into palindromic units, also called repetitive extragenic palindromes, the basic element of bacterial interspersed mosaic elements (BIMEs), which are found in intergenic regions of enterobacteria closely related to E. coli and Salmonella. We could not detect transposition onto a plasmid carryi...

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.

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.

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

[Participation of mobile element hobo in transposition events in the long-term instability system of Drosophila melanogaster].  

Science.gov (United States)

The lines with an active hobo elements as well as those without any hobo fragments were hybridized with the y2sc1waG line. This resulted in the appearance of a number of mutations at the white, miniature, and some other loci. The authors analysed, in which way the hobo transposable elements take part in mutagenesis in these crosses. Most of the white mutants obtained were analysed and transpositions of hobo and Stalker elements were demonstrated. Both independent and simultaneous transpositions were found. It was shown by means of the Southern blot analysis that additional hobo or Stalker insertion into or close to the parental unknown waG insertion resulted in mutant white phenotype's shift toward both extreme and partial reversion. Possible participation in mutagenesis of other mobile elements is also under debate. PMID:1338197

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.)

Diagnosis of uterine vein thrombosis on transvaginal ultrasound.  

Science.gov (United States)

Deep venous thrombosis (DVT) is a potentially serious medical disorder, which may result in pulmonary embolism and death. Compression ultrasound is the investigation modality of choice for the diagnosis of DVT of the lower limb. Diagnosis of proximal thrombosis involving the pelvic veins is difficult and is usually made only after the thrombus extends into the veins of the lower limb. We present six cases of incidental uterine vein thrombosis diagnosed by transvaginal ultrasound. Our aim is to describe the technique of the examination of pelvic veins and criteria that could be used to diagnose uterine vein thrombosis. We also highlight difficulties in the management of women diagnosed with asymptomatic uterine vein thrombi as there is little evidence to guide clinicians in choosing between different treatment options.

Acupuncture Points of the Horse’s Distal Thoracic Limb: A Neuroanatomic Approach to the Transposition of Traditional Points  

Directory of Open Access Journals (Sweden)

Full Text Available Veterinary acupuncture charts were developed based on the concept of transpositional points whereby human acupuncture maps were adapted to animal anatomy. Transpositional acupuncture points have traditionally been placed in specific locations around the horse’s coronet and distal limb believed to be the closest approximation to the human distal limb points. Because the horse has a single digit and lacks several structures analogous to the human hand and foot, precisely transposing all of the human digital points is not anatomically possible. To date there is no published research on the effect of acupuncture treatment of the equine distal limb points. This paper presents a modified approach to equine distal limb point selection based on what is known from research on other species about the neuroanatomic method of acupuncture. A rationale is presented for modification of traditional equine ting points as well as additional points around the hoof and distal limb that do not appear in the standard textbooks of equine acupuncture. The anatomy and physiology of the equine foot likely to be affected by acupuncture are briefly reviewed. Modified neuroanatomic points are proposed that may be more accurate as transpositional points. As an example of clinical application, a neuroanatomic approach to acupuncture treatment of equine laminitis is presented.

Preservation of systemic tricuspid valve function by pulmonary conduit banding in a patient with corrected transposition of the great arteries  

Science.gov (United States)

Systemic tricuspid valve regurgitation increases mortality and morbidity in patients with a corrected transposition of the great arteries. A 17-year old male with a physiologically corrected transposition after the closure of a ventricular septal defect and conduit placement between a morphological left ventricle and pulmonary artery presented with exertional dyspnoea. The transthoracic echocardiography showed a severe conduit stenosis, and cardiac catheterization revealed a pressure gradient of 114 mmHg. The patient underwent conduit re-replacement using a pulmonary heterograft. Intraoperative transoesophageal echocardiography revealed an acute severe tricuspid regurgitation after a conduit re-replacement. Pulmonary conduit banding was performed under transoesophageal echocardiography guidance, during which the left ventricular to right ventricular pressure ratio increased from 0.33 to 0.60 and the degree of tricuspid regurgitation decreased mildly. The patient was discharged uneventfully at postoperative day 16. Conduit banding might be a useful technique to preserve the systemic tricuspid valve function during conduit re-replacement in patients with a corrected transposition. PMID:22572412

Functional reorganization of human motor cortex after unaffected side C7 nerve root transposition  

International Nuclear Information System (INIS)

Objective: To assess the characteristics of neuronal activity in human motor cortex after the seventh cervical nerve root transposition of the unaffected side by using functional MRI (fMRI). Methods: Thirteen patients who accepted the seventh cervical nerve root transposition of the unaffected side, due to total brachial plexus traction injury diagnosed by manifestation and operation, were examined retrospectively by using fMRI. 10 patients were injured on the left side and 3 on the right side. According to functional recovery of the affected hand, all subjects can be divided into 2 groups. The patients of the first group could not move the affected hand voluntarily. The patients of the second group could move the affected hand self-determined. 12 healthy volunteer's were also involved in this study as control. The fMRI examinations were performed by using echo-planer BOLD sequence. Then the SPM 99 software was used for post-processing. Results: The neuronal activation induced by the movement of both unaffected and affected upper' limb was seen in the contralateral PMC in all patients; Neuronal activation in the ipsilateral PMC evoked by movement of the unaffected extremity was seen in 10 cases, and induced by movement of the affected limb was seen in 7 cases. In the first group, the sharp of clusters in the contralateral PMC resulted by movement of the unaffected extremity showed normal in 9 eases, the average size of clusters resulted by the unaffected hand was 3159s resulted by the unaffected hand was 3159 (voxel), and resulted by the unaffected shoulder was 1746(voxel). The sharp of clusters in the contralateral PMC resulted by the affected shoulder or hand were revealed enlargement in 6 cases of each. In the second group, 1 case showed neuronal activation induced by movement of the affected limb in the PMC in both sides of motor cortex, and 2 cases showed neuronal activation in the contralateral PMC. Conclusions: Peripheral nerve injury was able to cause changes of motor cortex in human brain. Cortical area devoted to the affected extremity seems to persist for a long time with response to mental representation of movement. The functional reorganization of central nerve system may be present in several levels of the central nerve system and may be affected by multiple factors. (authors)

TE-Tracker: systematic identification of transposition events through whole-genome resequencing.  

Science.gov (United States)

BackgroundTransposable elements (TEs) are DNA sequences that are able to move from their location in the genome by cutting or copying themselves to another locus. As such, they are increasingly recognized as impacting all aspects of genome function. With the dramatic reduction in cost of DNA sequencing, it is now possible to resequence whole genomes in order to systematically characterize novel TE mobilization in a particular individual. However, this task is made difficult by the inherently repetitive nature of TE sequences, which in some eukaryotes compose over half of the genome sequence. Currently, only a few software tools dedicated to the detection of TE mobilization using next-generation-sequencing are described in the literature. They often target specific TEs for which annotation is available, and are only able to identify families of closely related TEs, rather than individual elements.ResultsWe present TE-Tracker, a general and accurate computational method for the de-novo detection of germ line TE mobilization from re-sequenced genomes, as well as the identification of both their source and destination sequences. We compare our method with the two classes of existing software: specialized TE-detection tools and generic structural variant (SV) detection tools. We show that TE-Tracker, while working independently of any prior annotation, bridges the gap between these two approaches in terms of detection power. Indeed, its positive predictive value (PPV) is comparable to that of dedicated TE software while its sensitivity is typical of a generic SV detection tool. TE-Tracker demonstrates the benefit of adopting an annotation-independent, de novo approach for the detection of TE mobilization events. We use TE-Tracker to provide a comprehensive view of transposition events induced by loss of DNA methylation in Arabidopsis. TE-Tracker is freely available at http://www.genoscope.cns.fr/TE-Tracker.ConclusionsWe show that TE-Tracker accurately detects both the source and destination of novel transposition events in re-sequenced genomes. Moreover, TE-Tracker is able to detect all potential donor sequences for a given insertion, and can identify the correct one among them. Furthermore, TE-Tracker produces significantly fewer false positives than common SV detection programs, thus greatly facilitating the detection and analysis of TE mobilization events. PMID:25408240

Fracturing of rocks due to tectonic stresses or local high fluid pressures and the formation of fluid pathways is important for a whole range of industrially relevant processes in the Earth's upper crust reaching from groundwater transport, hydrocarbon migration to geothermal systems. Fracturing and the opening of fluid pathways become especially important in tight rocks where fluid migration through the rock matrix is restricted. In addition observations show that fractures are often partly or completely sealed and occur as veins in geological systems. How can we interpret the permeability of these vein systems? The internal structure of veins often indicates that they are formed by several cracking and sealing events. In addition some geological systems contain partly sealed veins that have a preserved porosity and may add to the overall permeability of the system. We are comparing field areas that contain different vein patterns with hydrodynamic numerical models where fractures develop as a function of gravity, extension and fluid pressure gradients. In addition fractures seal where the developing veins can have variable properties in terms of elasticity, breaking strength and porosity. Results indicate that permeability in such systems is not a constant but may vary strongly over time. In an active system the amount of veins and number of open fractures depends not only on the timing of sealing but also on the breaking strength of the veins. Strong veins can clog the system whereas weak veins tend to lead to possible connected fracture networks. In addition one cannot link veins directly to fluid flow, intense veining does not mean that the system has or had a high permeability. We will present a first attempt to classify different fracturing and sealing systems based on field observations and numerical models.

Intimal proliferation in an organ culture of human saphenous vein.  

OpenAIRE

This study investigated whether intimal proliferation, the characteristic feature of the response of human saphenous vein to arterial implantation, also occurs in organ culture. Vein segments were maintained for 14 days in medium supplemented with 30% fetal bovine serum. Tissue viability (measured by adenosine triphosphate [ATP] concentration) decreased only 20% from 280 +/- 20 to 220 +/- 20 nmol/g wet weight. In veins prepared for culturing, endothelial loss (approximately 20%) was confined ...

Percutaneous intrahepatic portosystemic shunt created via a femoral vein approach.  

Science.gov (United States)

Creation of a percutaneous intrahepatic portosystemic shunt was attempted in a patient with portal hypertension and acute variceal hemorrhage. Abnormal hepatic venous anatomy precluded formation of the shunt with the standard transjugular method. An alternate technique was devised in which a femoral vein approach was used to construct an intrahepatic channel between the inferior right hepatic vein and the right portal vein. The patient stopped bleeding after the procedure and has not rebled during an 8-month follow-up period. PMID:1947081

Palm-Vein Classification Based on Principal Orientation Features  

OpenAIRE

Personal recognition using palm–vein patterns has emerged as a promising alternative for human recognition because of its uniqueness, stability, live body identification, flexibility, and difficulty to cheat. With the expanding application of palm–vein pattern recognition, the corresponding growth of the database has resulted in a long response time. To shorten the response time of identification, this paper proposes a simple and useful classification for palm–vein identification based ...

Finger Vein Recognition Based on Personalized Weight Maps  

OpenAIRE

Finger vein recognition is a promising biometric recognition technology, which verifies identities via the vein patterns in the fingers. Binary pattern based methods were thoroughly studied in order to cope with the difficulties of extracting the blood vessel network. However, current binary pattern based finger vein matching methods treat every bit of feature codes derived from different image of various individuals as equally important and assign the same weight value to them. In this paper...

Clinical pharmacology, physiology and pathophysiology of superficial veins--1.  

OpenAIRE

1. Venous resistance contributes very little to total peripheral resistance; more than half of the total blood volume, however, is contained in the extrathoracic veins. Owing to marked differences between venous and arterial anatomy and physiology, studies on veins and arteries usually require different methodological approaches. Whereas for arteries the most relevant parameters are resistance, pressure and flow, for veins volume and compliance are most important. For studies of general aspec...

Partial anomalous connection of both superior pulmonary veins.  

Science.gov (United States)

Several patterns of anomalous pulmonary venous drainage have been described in the literature, and bilateral partial pulmonary anomalous vein connection (PAPVC) has been described as a rare congenital cardiac anomaly. We report an unusual type of bilateral PAPVC, involving both the superior right and left pulmonary veins draining into the left brachiocephalic vein in a young adult who was symptomatic with dyspnea and a dry cough.

Medical treatment of retinal vein occlusions.  

Science.gov (United States)

The medical treatment of retinal vein occlusion (RVO) is comprised of three main stages: identification and therapy of the detectable risk factors, specific treatment aimed at the occlusive form and treatment of RVO complications. Even though the possible medical management of RVO includes several treatments, the most interesting approaches have been: anticoagulant/antiaggregating agents, troxerutin, corticosteroid, fibrinolytic/thrombolytic agents, and hemodilution. Overall, the medical approach to RVO is still awkward and unsatisfactory. Randomized clinical trials are needed to assess the degree of efficacy of the medical treatment of the specific forms of RVO.

Unilateral pulmonary vein atresia: A case report  

Energy Technology Data Exchange (ETDEWEB)

Unilateral pulmonary vein atresia is a rare congenital anomaly. Its symptoms begin to manifest in childhood and a broad spectrum of clinical severity has been described, ranging from asymptomatic, recurrent pulmonary infection, severe hemoptysis, to death. Only a few adult cases with this condition, with no or mild symptoms, have been reported. Pulmonary angiography has been typically used for definite diagnosis. However, pulmonary angiography may be replaced with the current developing multidetector CT. This report presents an adult case with mild symptoms, diagnosed by multidetector CT.
