Primary patency time of basilic vein transposition versus prosthetic brachioaxillary access grafts in hemodialysis patients.  

UK PubMed Central (United Kingdom)

PURPOSE: The aim of this study was to compare the primary patency time of basilic vein transposition and prosthetic brachioaxillary access grafts in hemodialysis patients. METHODS: In this randomized clinical trial, 60 hemodialysis patients who met the inclusion/exclusion criteria were recruited and randomly assigned to two intervention groups; Basilic vein transpositions (BVT) or Arteriovenous access grafts (AVG). Clinical follow-up for patency of the created accesses in at least one year, was performed at two weeks, one, two, three months and then every three months after surgery. Finally, patency rates and access-related complications were compared in the two groups studied. RESULTS: Thirty BVTs and thirty AVG were performed in each group studied. The groups were well matched for age, sex and comorbidity. After at least one year of follow-up, the access failure rate in the BVT and AVG groups was 23.3% and 30%, respectively. In addition, the mean primary patency time in the BVT and AVG groups was 244.13 ± 103.65 and 264.97 ± 149.28, respectively and there was no statistically significant difference between the two groups studied (P=.533). The common cause of access failure were thrombosis and infection but there were no statistically significant differences between the two groups (P>.05). CONCLUSION: Our results show that AVG offer similar patency and complication rates to BVT. Thus, authors consider them as the preferred hemodialysis access when there are no suitable forearm veins to create arteriovenous fistulas.

Outcomes of brachial artery-basilic vein fistula.  

Science.gov (United States)

Increasing the creation of arteriovenous fistulas in the maintenance of hemodialysis patients is of great importance to the nephrology community. The creation of the brachial artery-basilic vein fistula is an important option in patients with unsuccessful or failing forearm accesses for hemodialysis. The aim of this study is to review reported outcomes of brachial artery-basilic vein fistulas regarding patency and primary failure rates in comparison with other types of fistulas and grafts in the published literature. We have also described the variations in the surgical technique during creation and the potential influence on outcomes. Based on our review of the literature, the rate of primary failure is approximately 15-20% with a range of 0-40%. The mean 1-year primary patency rate is approximately 72% with a range of 23-90%, and the 2-year primary patency rate is approximately 62% with a range from 11% to 86%. The number of required interventions to maintain patency is lower with brachial artery-basilic vein fistula compared to arteriovenous grafts. PMID:21480998

Primary brachial vein transposition for hemodialysis access: report of a case and review of the literature.  

UK PubMed Central (United Kingdom)

The superiority of autogenous fistulae in patients with end-stage renal disease, performing hemodialysis, is well established and largely accepted. However, in case that superficial veins in the upper arm are not available for fistula construction, brachial vein transposition may be a viable alternative prior to graft placement. This transposition could be done as a primary or staged procedure, depending on the vein size. We present the case of a 63-year-old male patient with a thrombosed arteriovenous graft in the forearm and a large brachial vein in the ipsilateral upper arm. A one-stage (primary) brachial vein transposition was performed. The fistula, 10 months after its construction, is still patent. No complications have occurred.

[Homolateral transposition of the internal jugular vein for axillo-subclavian venous thrombosis (of effort)].  

UK PubMed Central (United Kingdom)

UNLABELLED: Indications for treating subclavian vein obstruction are still being developed, especially for endovascular procedures with or without first rib resection. This article explores our experience with chronic and acute subclavian vein thrombosis persisting after medical treatment. In our department of vascular surgery, we have observed 2 cases of subclavian vein obstruction in 2 patients with Paget-Schroetler syndrome who developed major pain and edema in the dominant upper limb. Initially, we managed these patients medically with thrombolysis and anticoagulation. Then, as the significant symptoms persisted and venous thrombolysis developed, we decided on surgical treatment. Because of hypertrophic venous impairment, we used an aggressive procedure with venous bypass using jugular vein transposition and temporary arteriovenous fistula. We observed significant symptom relief and also perfect permeability of the venous bypass at 30 months. CONCLUSION: On the basis of our anecdotal experience and reports by other groups, aggressive treatment with decompression (first rib resection and scalenectomy) and jugular vein transposition could be recommended for persistent subclavian vein thrombosis. Because of the presence of a thoraco-brachial outlet syndrome the endovascular procedures should be completed by first rib resection.

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

International Nuclear Information System (INIS)

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

Scientific Electronic Library Online (English)

Full Text Available Abstract in portuguese OBJETIVO: Determinar parâmetros anátomo-cirúrgicos para o acesso rápido, seguro e preciso da veia basílica no terço distal do braço e avaliar os aspectos anatômicos relacionados à presença, número e sintopia neural na região. MÉTODO: Foram utilizados 30 membros superiores de cadáveres adultos, brasileiros, do sexo masculino (27 a 58 anos), fixados em solução de formalina a 10%. Foi criado um método trigonométrico utilizando-se parâmetros anatômicos, de (more) terminando-se um triângulo cujo ápice foi o ponto de referência para a localização da veia basílica no terço distal do braço. A região foi dissecada e a veia exposta. O método foi também utilizado na dissecação venosa de 15 pacientes. RESULTADOS: A veia basílica foi encontrada na face medial do terço distal do braço de todos os cadáveres, localizando-se no ápice do trígono em 70% dos casos e em situação medial em relação ao mesmo em 30%. Em 83,33% havia ramos dos nervos cutâneos mediais do braço e antebraço junto à adventícia da veia basílica. Foram encontrados dois ramos dos nervos cutâneos mediais do braço e antebraço relacionados a cada veia basílica em 90% dos membros superiores e apenas um ramo no restante. Em 30% dos casos existiam ramos posteriores à veia basílica, o que deve ser considerado ao se realizar a dissecação da mesma. CONCLUSÕES: O método proposto para a localização da veia basílica mostrou-se eficaz, rápido, seguro e preciso, indicando ser uma boa opção de acesso venoso no paciente em estado crítico que necessite de tal procedimento. Abstract in english BACKGROUND: To determine anatomo-surgical parameters to fast, safe and precise approach to the basilic vein in the arm distal third and to assess anatomic features related to the presence, and nerve sintopy in the region. MATERIAL AND METHODS: The study was made in 15 human corpses, from male adults aged 27 up to 58 years old, summing up 30 upper limbs, fixed in 10% formalin. It was created a trigonometric method using anatomic parameters to determine a triangle which ape (more) x was the reference point to locate the basilic vein in the arm distal third. The region was dissected, the vein exposed, its diameter assessed with a caliper. The method was utilized to perform the basilic vein dissection in 15 patients that required the venous approach. RESULTS AND CONCLUSION: The basilic vein was found in the medial surface of arm distal third in all studied cadavers. The vein was located on the triagle apex in 70% of the cases (87% of the right and 53% of the left upper limbs). In 30% of the specimens the vein was placed medially to the triangle apex, the distance did not exceeded 5mm. In 83,33% of the specimens there were branches of the medial cutaneous nerves of arm and forearm against the vein adventitia. It was found two branches of the medial cutaneous nerves of arm and forearm related to each basilic vein in the majority of the upper limbs (90% - 27 limbs) and only one branch in the remaining (10 % - 3 limbs). In 30% of the cases there were branches located behind the basilic vein, this fact must be considered when the basilic vein dissection is made. The proposed method to the basilic vein location showed to be fast, safe and precise, indicating that the method is a good option to the vascular approach in patients in critical conditions that demand this procedure.

Ipsilateral jugular to distal subclavian vein transposition to relieve central venous hypertension in rescue vascular access surgery: a surgical report of 3 cases.  

UK PubMed Central (United Kingdom)

Central venous thrombosis may often arise following central venous cannulation for temporary haemodialysis access. Venous thrombosis may be clinically asymptomatic due to the presence of collateral circulation. However, if an arteriovenous (AV) fistula is prepared below the obstructed venous segment, then symptoms may occur. Central venous hypertension interferes with dialysis, compromises limb function and threatens its safety. Percutaneous treatment is mostly used. However, in some cases endovascular treatment may not be as easy and long term patency uncertain.We report our experience on 3 patients on chronic hemodialysis treatment presenting with a patent AV fistula and ipsilateral subclavian vein chronic fibrotic obstruction. They were treated by ipsilateral internal jugular to distal subclavian vein transposition. Two separate surgical incisions were performed to expose the subclavian vein distally to the occlusion and the jugular vein that was distally ligated and transposed. There was no mortality nor significant postoperative complications. Resolution of hypertensive symptoms was achieved within 3-4 weeks in all patients. The AV fistula was used for dialysis treatment starting from the first postoperative day. At follow-up (mean 13 months), there was no recurrence of upper limb venous hypertension.In patients with subclavian occlusion and ipsilateral low flow, patent AV fistula, jugular to distal subclavian vein transposition may prove useful in cases when percutaneous angioplasty is technically not feasible or long term patency is not expected.

Transposition game  

CERN Document Server

We introduce a two-player game, in which each player extends a given sequence by picking a free element in a domain D of the real line. The aim of the players is to control the parity of the number of transpositions necessary to put the final sequence in order. We will see that the winner can be the last player, the second last player, the first player, the second player, the person who wants the parity to end up even or the person who wants the parity to end up odd. A special case of the game can be reduced to a game with nontrivial winning strategy, but describable in so simple a way that children can understand it and enjoy playing it.

As the portal vein was inadequate in each case, the left gastric vein (two cases) or the inferior mesenteric vein was isolated, tied distally, transposed and anastomosed to the donor portal vein. RESULTS: In all three cases the reperfusion was apparently satisfactory and the postoperative course was uneventful. Doppler ultrasonography and liver function tests confirmed the sufficiency of the portal flow. CONCLUSION: The left gastric vein or the inferior mesenteric vein may be a good alternative to portal reconstruction in liver transplant.

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

Directory of Open Access Journals (Sweden)

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

Regulation of RAG transposition.  

Science.gov (United States)

V(D)J recombination is initiated by the lymphoid specific proteins RAG1 and RAG2, which together constitute the V(D)J recombinase. However, the RAG 1/2 complex can also act as a transposase, inserting the broken DNA molecules generated during V(D)J recombination into an unrelated piece of DNA. This process, termed RAG transposition, can potentially cause insertional mutagenesis, chromosomal translocations and genomic instability. This review focuses on the mechanism and regulation of RAG transposition. We first provide a brief overview of the biochemistry of V(D)J recombination. We then discuss the discovery of RAG transposition and present an overview of the RAG transposition pathway. Using this pathway as a framework, we discuss the factors and forces that regulate RAG transposition. PMID:19731798

Preservation of arm veins for arterial reconstruction.  

Science.gov (United States)

The results of surgery for lower extremity salvage have improved steadily over the past decade. One of the principles accounting for this advance is the preferential use of autogenous veins for peripheral bypass surgery. Nonautogenous and prosthetic grafts to the infrageniculate (below knee) level have patency rates significantly lower than autogenous bypasses. Currently, the technical limits of bypass surgery often depend upon the availability of adequate venous conduits. The saphenous vein has been the conduit of choice for distal arterial bypasses. However, some patients lack saphenous veins as a result of previous vein harvesting for coronary or other arterial surgery, phlebitis, variations in venous anatomy, previous vein stripping, or other conditions. In these patients, arm veins (cephalic and basilic) have been used successfully for limb salvage. There are several requirements for the successful use of arm veins. These include a detailed knowledge of the anatomy of the cephalic and basilic veins, education of patients and health care professionals, nursing protocols to preserve arm veins, and the training of surgical nurses in the demanding technical maneuvers for arm vein implantation. This paper will address these subjects. PMID:1599859

Congenitally corrected transposition  

Directory of Open Access Journals (Sweden)

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

Inferior alveolar nerve lateral transposition.  

UK PubMed Central (United Kingdom)

PURPOSE: We determined the outcomes of 18 inferior alveolar nerve lateral transposition procedures in 15 consecutive patients. The advantages and disadvantages of this technique are discussed. RESULTS: The surgical protocol for inferior alveolar nerve transposition, followed by implant placement, presented excellent results, with complete recovery of the sensitivity within 6 months after the surgical procedure. DISCUSSION: Inferior alveolar nerve transposition is an option for prosthetic rehabilitation in cases of moderate or even severe bone reabsorption for patients that do not tolerate removable dentures. CONCLUSIONS: It is concluded that inferior alveolar nerve transposition can be safely and predictably performed with low risk to the mental nerve sensibility. Each patient should be advised of the chance of permanent nerve deficit throughout the distribution of the mental nerve. Alternative restorative solutions should also be considered.

Antioxidant properties of various solvent extracts from purple basil.  

UK PubMed Central (United Kingdom)

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

Preoperative noninvasive assessment of arm veins to be used as bypass grafts in the lower extremities.  

UK PubMed Central (United Kingdom)

Preoperative noninvasive imaging of the veins of the upper extremities has been included in the protocol to select an autogenous vein for a distal bypass in the lower extremity. Arm veins are sought as bypass grafts when the saphenous vein is absent or not usable. Duplex ultrasound provided images of the cephalic and basilic veins in 10 patients in whom visual inspection failed to reveal usable grafts. All arm veins implanted were at least 2 mm (range 2 to 6 mm) in internal diameter determined by ultrasound and were, on the average, 2 mm larger when unroofed. This noninvasive technique has decreased the number of fruitless surgical explorations to obtain a suitable arm vein and has increased the use of arm veins by revealing veins previously not anticipated by physical examination, which virtually eliminated the use of nonautogenous conduits in our practice.

The BASIL survival prediction model in patients with peripheral arterial disease undergoing revascularization in a university hospital setting and comparison with the FINNVASC and modified PREVENT scores.  

UK PubMed Central (United Kingdom)

BACKGROUND: Critical limb ischemia carries a significant risk of morbidity and mortality. The development of scores to predict risk can aid clinical decision making. The Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL) trial investigators developed a model to predict death, which has not been previously validated. METHODS: Data were collected in a prospectively maintained database on all patients who underwent angioplasty or arterial bypass for peripheral artery disease in a university hospital between January 2008 and June 2010. The main outcome measures were all-cause mortality and amputation-free survival at 3, 6, 12, and 24 months after the index intervention. The BASIL survival predictor, Finland National Vascular (FINNVASC) registry, and Edifoligide for the Prevention of Infrainguinal Vein Graft Failure (PREVENT) models were applied and receiver-operating characteristic (ROC) curve analysis was used to evaluate their predictive power. RESULTS: Data on 342 patients were collected. Patients with isolated iliac disease or claudication were excluded. The 6-, 12-, and 24-month all-cause mortality rates were 11.6%, 17.9%, and 26.8%, respectively. The area under the ROC curve (95% confidence interval) using the BASIL score to predict mortality at 6, 12, and 24 months was 0.700 (0.60-0.80; P<.001), 0.651 (0.56-0.74; P<.003), and 0.681 (0.59-0.74; P<.001), respectively. ROC curve analysis indicated that the performance of the BASIL score in this cohort was comparable to other validated predictive scores. CONCLUSIONS: The BASIL survival prediction model can moderately predict short-term and medium-term mortality in patients with limb ischemia and may be a useful adjunct to decision making in everyday clinical practice.

In vitro Anti-Helicobacter pylori Effects of Sweet Basil (Ocimum basilicum L.) and Purple Basil (Ocimum basilicum var. purpurascens)  

Directory of Open Access Journals (Sweden)

Full Text Available Anti-Helicobacter pylori effects of leaves of Ocimum basilicum L. (sweet basil, Lamiaceae) and Ocimum basilicum var. purpurascens (purple basil, Lamiaceae) were evaluated. Macerated aqueous and methanol extracts were tested against 45 clinical isolates of Helicobacter pylori using paper Disc Diffusion Method (DDM) on modified egg yolk emulsion agar (EYE agar). Although there were small differences in sensitivity among the isolates tested, but all isolates were susceptible to methanol and aqueous extracts. The Minimum Inhibitory Concentrations (MIC) of the extracts from leaves of sweet basil and purple basil were 677 and 729 ?g mL-1, respectively using agar dilution method. Antibacterial constituents of sweet basil extract were stable after one month of storage at 4°C but lost 31% its activity after 4 weeks at room temperature. The extract preserved its activity when heated to 80°C for 30 min and autoclaved at 121°C for 20 min. It was stable at pH 5-8.

Essential oil from Ocimum basilicum (Omani Basil): a desert crop.  

UK PubMed Central (United Kingdom)

The focus of the present study was on the influence of season on yield, chemical composition, antioxidant and antifungal activities of Omani basil (Ocimum basilicum) oil. The present study involved only one of the eight Omani basil varieties. The hydro-distilled essential oil yields were computed to be 0.1%, 0.3% and 0.1% in the winter, spring and summer seasons, respectively. The major components identified were L- linalool (26.5-56.3%), geraniol (12.1-16.5%), 1,8-cineole (2.5-15.1%), p-allylanisole (0.2-13.8%) and DL-limonene (0.2-10.4%). A noteworthy extra component was beta- farnesene, which was exclusively detected in the oil extracted during winter and spring at 6.3% and 5.8%, respectively. The essential oil composition over the different seasons was quite idiosyncratic, in which the principal components of one season were either trivial or totally absent in another. The essential oil extracted in spring exhibited the highest antioxidant activity (except DPPH scavenging ability) in comparison with the oils from other seasons. The basil oil was tested against pathogenic fungi viz. Aspergillus niger, A. fumigatus, Penicillium italicum and Rhizopus stolonifer using a disc diffusion method, and by determination of minimum inhibitory concentration. Surprisingly high antifungal values were found highlighting the potential of Omani basil as a preservative in the food and medical industries.

Application of high Cu compost to Swiss chard and basil.  

UK PubMed Central (United Kingdom)

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.

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

UK PubMed Central (United Kingdom)

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.

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.

Gracilis muscle transposition for iatrogenic rectourethral fistula.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To assess the utility of gracilis muscle transposition in the treatment of iatrogenic rectourethral fistula. SUMMARY BACKGROUND DATA: Iatrogenic rectourethral fistula poses a rare but challenging complication of treatment for prostate cancer. A variety of procedures have been described to treat this condition, none of which has gained acceptance as the procedure of choice. The aim of this study was to review the authors' experience with gracilis muscle transposition in the treatment of iatrogenic rectourethral fistula. METHODS: A retrospective chart review of all patients who underwent gracilis muscle transposition for iatrogenic rectourethral fistula was performed, and follow-up was established by telephone interview. Successful repair was defined as absence of a fistula after reversal of fecal and urinary diversions. RESULTS: Eleven men, mean age of 62 years, underwent 12 gracilis muscle transpositions for rectourethral fistula between 1996 and 2001. Six patients had a history of pelvic radiotherapy, and five patients had previous failed attempts to repair the fistula. In nine patients, the fistula healed following gracilis muscle transposition. One patient developed a rectocutaneous fistula that healed with fibrin glue injection, and one developed perineal sepsis requiring debridement of the transposed gracilis. This patient underwent a second gracilis transposition, which uneventfully healed. Overall, all of the patients had closure of their diverting stomas and maintained healed rectourethral fistulas. There were no intraoperative complications, and the only long-term complication of this procedure was mild medial thigh numbness in two patients. CONCLUSIONS: Gracilis muscle transposition is an effective surgical treatment for iatrogenic rectourethral fistula. It is associated with low morbidity and a high success rate.

Antioxidant capacity and phenolic content of holy basil  

Directory of Open Access Journals (Sweden)

Full Text Available The antioxidant capacity of white and red holy basil leaves (Ocimum sanctum Linn., white and red varieties) from fresh markets in Chiang Mai was estimated by three different methods; ferric reducing antioxidant power (FRAP) assay, improved ABTS radical cation decolorization assay, and DPPH free radical scavenging activity; together with their total phenolic contents. Water and 95% ethanol ratios of extraction solvents were also studied, and it was found that 57 and 76% ethanol solvents were more suitable in this study. All three antioxidant capacity assays showed that red holy basil was higher in antioxidant capacity than white holy basil (p<0.05). ABTS values were higher than FRAP and DPPH values, respectively, because of their different mechanisms, but their significant correlation (p<0.01) expressed their similar trends. In addition, correlation between results of all antioxidant capacity and total phenolic content was found (p<0.01). ABTS values were highly correlated into the results of total phenolic content than were FRAP and DPPH values.

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

Energy Technology Data Exchange (ETDEWEB)

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.)

Permanent magnet machine with windings having strand transposition  

Science.gov (United States)

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

Mutagen activated transposition of AhMITE1 in peanut  

International Nuclear Information System (INIS)

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

Heuristics for the transposition distance problem.  

UK PubMed Central (United Kingdom)

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

Antibacterial Activity of the Essential Oils of Sudanese Accessions of Basil (Ocimum basilicum L.)  

Directory of Open Access Journals (Sweden)

Full Text Available This study is concerned with the evaluation of antibacterial activity of the essential oils of the most commonly grown ornamental-type basils (five types) as well as that of wild-type basil which spontaneously grows in large pure stands during the rainy season. The essential oils of all six basil types showed strong antibacterial activity against E. coli, Staphylococcus aureus and Salmonella typhimurium. This activity was dose-dependent. Calculated LD50 values varied between 40 and 325 ?L of crude essential oil/well, for the three bacteria, using the agar well diffusion method. The crude essential oil of wild Sudanese basil, assayed by the disc diffusion method, had three TLC-separated compounds which were active against Salmonella typhimurium. One of these was identified as geraniol, a major constituent of the essential oil. Thus basil essential oil has potential clinical or food applications as an antibacterial agent.

Antibacterial activity of lemon, caraway and basil extracts on Listeria spp.  

Directory of Open Access Journals (Sweden)

Full Text Available Commercial extracts of three spices (lemon, caraway and basil) against Listeria monocytogenes, L. innocua and L. welshimeri were investigated using disc diffusion method. Lemon and basil extracts inhibited all the organisms at the level of ? 5 ?l (lemon) and 20 ?l (basil). These extracts produced inhibitory zones of 9-19 mm (lemon) and 8-11.5 mm (basil). The extract of caraway showed activity only against L. innocua at the highest level (20 ?l), producing an inhibitory zone of 14.7 mm. Generally, the lemon extract was the most effective. This extract exhibited greater inhibitory activity against L. monocytogenes, while the basil extract had the strongest effect on L. welshimeri. [Projekat Ministarstva nauke Republike Srbije, br.

Anterior intramuscular transposition of the ulnar nerve.  

UK PubMed Central (United Kingdom)

The surgical management of cubital tunnel syndrome is well documented in the literature. Anterior intramuscular transposition of the ulnar nerve is indicated for chronic cubital tunnel syndrome with symptoms refractory to conservative therapy. Prompt diagnosis is essential to yield excellent results. Extreme care must be exercised in the performance of anterior intramuscular transposition. The surgeon must know the details of medial epicondylar anatomy and pathophysiology, as well as all possible sites of potential nerve compression. The placement of the transposed nerve in an intramuscular bed requires that all fibrous septae are resected from the shallow trough created for the nerve to avoid scar formation. Postoperatively, the arm is immobilized for 3 weeks, after which range-of-motion exercises are begun. By the eighth postoperative week, most patients are able to resume their regular activities, including manual labor. Recurrence or persistence of symptoms postoperatively typically is traced to an inadequate decompression of the nerve. Common sites of persistent ulnar nerve compression include (1) the medial intermuscular septum, (2) the arcade of Struthers, (3) fibrous bands immediately proximal or distal to the cubital tunnel, (4) persistence or kinking at the arcuate ligament of Osborne, (5) Spinner's ligament or other fascial slings, and (6) incomplete anterior transposition. Anterior intramuscular transposition of the ulnar nerve is attractive for its relative ease of dissection, simplicity, reliability, and low morbidity. Transposition of the nerve into a shallow muscular trough deep only to the flexor-pronator fascia is a logical, effective, and consistently reliable method of treating cubital tunnel syndrome refractory to conservative management.

Survival of Pathogenic Escherichia Coli on Basil, Lettuce, and Spinach.  

UK PubMed Central (United Kingdom)

The contamination of lettuce, spinach and basil with pathogenic E. coli has caused numerous illnesses over the past decade. E. coli O157:H7, E. coli O104:H4 and avian pathogenic E. coli (APECstx- and APECstx+) were inoculated on basil plants and in promix substrate using drip and overhead irrigation. When overhead inoculated with 7 log CFU/ml of each strain, E. coli populations were significantly (P = 0.03) higher on overhead-irrigated plants than on drip-irrigated plants. APECstx-, E. coli O104:H4 and APECstx+ populations were recovered on plants at 3.6, 2.3 and 3.1 log CFU/g at 10 dpi (days post-inoculation), respectively. E. coli O157:H7 was not detected on basil after 4 dpi. The persistence of E. coli O157:H7 and APECstx- were similar when co-inoculated on lettuce and spinach plants. On spinach and lettuce, E. coli O157:H7 and APEC populations declined from 5.7 to 6.1 log CFU/g and 4.5 log CFU/g, to undetectable at 3 dpi and 0.6-1.6 log CFU/g at 7 dpi, respectively. The detection of low populations of APEC and E. coli O104:H4 strains 10 dpi indicates these strains may be more adapted to environmental conditions than E. coli O157:H7. This is the first reported study of E. coli O104:H4 on a produce commodity.

Effects of biocides on chlorophyll contents of detached basil leaves  

Directory of Open Access Journals (Sweden)

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

Spatial transposition gradients in visual working memory.  

UK PubMed Central (United Kingdom)

In list memory, access to individual items reflects limits of temporal distinctiveness. This is reflected in the finding that neighbouring list items tend to be confused most often. This article investigates the analogous effect of spatial proximity in a visual working-memory task. Items were presented in different locations varying in spatial distance. A retro-cue indicated the location of the item relevant for the subsequent memory test. In two recognition experiments, probes matching spatially close neighbours of the relevant item led to more false alarms than probes matching distant neighbours or non-neighbouring memory items. In two probed-recall experiments, one with simultaneous, the other with sequential memory item presentation, items closer to the cued location were more frequently chosen for recall than more distant items. These results reflect a spatial transposition gradient analogous to the temporal transposition gradient in serial recall and challenge fixed-capacity models of visual working memory (WM).

Corrected transposition of the great arteries  

Energy Technology Data Exchange (ETDEWEB)

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

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.

Comparing the growth and flowering of selected basil (Ocimum basilicum L.) varieties  

Directory of Open Access Journals (Sweden)

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

The effect of basil (Ocimum basilicum L.) on soil organic matter biodegradation and other soil chemical properties  

UK PubMed Central (United Kingdom)

The effects of basil (Ocimum basilicum L.) on soil organic matter biodegradation, nutritional mineral elements and bacterial colonies were studied in the laboratory. The air-dried basil plant tissues incorporated at five different rates (0, 1, 2, 3, and 4 g per 50 g of soil) resulted in increases in organic carbon mineralization, mineral nitrogen forms in organic phosphorus and available potassium. The level of available forms of manganese and zinc was increased at all the rates of added basil whereas copper was increased at the two upper rates. Also, the addition of basil resulted in a decrease in soil bacterial colonies. The results of this study indicated that the basil could be used as a cover crop for suppressing weed or pathogens in organic soils, with a positive effect on soil productivity. In addition, the incorporation of basil in soil could reduce the number of bacterial colonies. Copyright © 2007 Society of Chemical Industry

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.

Basil Bunting’s Aesthetic Function: Art vs. Intellect

Full Text Available Basil Bunting is most commonly thought of as 1930s and 1940s poet grouped with some other poets such as Louis Zukofsky and Lorine Niedecker under the label “Objectivist ”. The present researchers seek to achieve two goals in this paper. The fi rst goal is to argue that Bunting pushes the aesthetic function to the very brink of sense but holds it there, oscillating on the cusp of referential meaning, thus creating a contested, liminal space where sound and sense content for the constructive axis of meaning-construction. The second goal is to construct an oppositional relationship between art and intellect and conclude that if the best poetry aspires to a state of pure music, that aspiration moves it even further away from the intellect1. Reference will also be made to opponents who put sight and visuality over and above everything else in man’s effort to acquire knowledge of this world in general.Key words: Bunting; Aesthetics; Form; Art; Intellect; MusicRésumé Basil Bunting est le plus souvent considérés comme des années 1930 et 1940 de regroupés les poètes avec quelques autres poètes tels que Louis Zukofsky et Lorine Niedecker sous le label «objectiviste».

First Report of Black Leg of Hydroponic Basil in the United States Caused by Plectosporium tabacinum  

UK PubMed Central (United Kingdom)

During August 2007 and again in January 2008, compact sweet basil (Ocimum basilicum ‘Genovese’) plants grown hydroponically in Indiana displayed dark, irregular, stem lesions extending 2 to 3 cm above the interface of the nutrient solution. These necrotic stem lesions (black leg), observed on 20 to 30% of the basil plants caused very weak, brittle stems so that they could not be marketed fresh. Although no wilting was noted, reduced plant height was observed. Similar symptoms of blackleg and poor growth have been reported from Italy on greenhouse-grown basil infected with Microdochium tabacinum (1,2). Diseased plant samples were sent to diagnostic clinics at Purdue University and the University of Massachusetts. Stem samples were surface sterilized and plated on potato dextrose agar (PDA) acidified with 1 ml of 85% lactic acid per liter as well as onto one-quarter-strength PDA. A fungus morphologically consistent with Plectosporium tabacinum (van Beyma) M.E. Palm, W. Gams, & H.I. Nirenberg (synonyms M. tabacinum (von Arx, 1984) and Fusarium tabacinum (Gams & Gerlagh, 1968) (3) was cultured from the basil stems and identified as P. tabacinum by R. Wick. Cultures sent to J. McKemy and J. Bischof (USDA/APHIS/PPQ) and W. Elmer (Connecticut Agricultural Experiment Station) also were identified as P. tabacinum. Amplification of the 323-bp internal transcribed spacer (ITS) region (ITS1, 5.8S rRNA gene, ITS2) and subsequent BLAST alignments of the resulting sequence indicated a 98% match for Plectosphaerella cucumerina (anamorph P. tabacinum) (GenBank Accession No. U17399; MIDI Inc., Newark, DE). Inoculations were performed on basil plants grown in peat-based soilless medium in a greenhouse for 6 weeks. Immediately before inoculation, the roots were washed with tap water to remove the peat-based medium. A single basil plant was placed in each of eight, 125-ml Erlenmeyer flasks. Four flasks were filled with 100 ml of deionized water as negative controls and four were filled with a 1 × 10? CFU/ml water suspension of P. tabacinum so that the liquid reached the crown of the basil plant. Basil plants in the Erlenmeyer flasks were incubated on a laboratory bench at 23°C. After 24 h, the solutions in all flasks were discarded and each flask and root system was rinsed three times with deionized water. The plants were then incubated in deionized water on the laboratory bench for four to five additional days. Within 4 days, dark brown-to-black stem lesions similar to those observed originally on basil plants in the hydroponic production greenhouse developed on the plants at the water interface and extended up the stem. Lesions extended a mean of 22 mm above the water level on inoculated plants. Control plants remained symptomless. P. tabacinum was recovered from symptomatic tissue of inoculated plants to complete Koch's postulates. The experiment was repeated several times with similar results. Further evidence of pathogenicity was obtained by stem inoculation of basil plants growing in a soilless medium. These data indicate that P. tabacinum was the causal agent of the symptoms observed on the hydroponic basil. To our knowledge, this is the first report of P. tabacinum causing ‘black leg’ and reduced growth on basil in the United States and the first report in the world of P. tabacinum on hydroponic basil.

Volatile composition of sweet basil essential oil (Ocimum basilicum L.) as affected by drying method  

UK PubMed Central (United Kingdom)

The influence of drying method on aroma compounds of sweet basil (Ocimum basilicum L.) was evaluated. The drying methods tested were convective (CD) and vacuum-microwave (VMD), as well as a combination of convective pre-drying and VM finish-drying (CPD–VMFD). Sweet basil's drying kinetics for CD was described by a two term exponential model, while VMD kinetics consisted of two periods: linear until a critical point and exponential beyond that point. Volatile compounds of basil samples were extracted by hydrodistillation and analyzed by GC/FID and GC/MS. Forty compounds were tentatively identified, with methyleugenol, eugenol, eucalyptol, and linalool being the major components. The total quantity of volatiles of fresh sweet basil, 32.1gkg?1, decreased considerably during both CD and VMD, 14.4gkg?1. The CPD-VMFD (40°C and 360W) was the best option for drying sweet basil, the time required was relatively short (?250min), and aroma quality was good according to instrumental data (total concentration of volatiles 16.7gkg?1) and sensory data (high intensities of fresh and floral notes).

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.

Antimicrobial activity of basil (Ocimum basilicum) oil against Salmonella enteritidis in vitro and in food.  

UK PubMed Central (United Kingdom)

Nine essential oils were examined for antimicrobial activity against reference and clinical strains of Salmonella Enteritidis. Based on the size of the inhibition zone and the minimal inhibitory concentration, basil oil had the strongest antimicrobial activity against all the tested bacteria, and S. Enteritidis SE3 was the most sensitive strain to all the tested oils. Gas chromatography/mass spectrometry analysis revealed that the major constituents of the oil were linalool (64.35%), 1,8-cineole (12.28%), eugenol (3.21%), germacrene D (2.07%), alpha-terpineol (1.64%), and rho-cymene (1.03%). When applied in nham, a fermented pork sausage, experimentally inoculated with S. Enteritidis SE3 and stored at 4 degrees C, basil oil inhibited the bacterium in a dose-dependent fashion. Basil oil at a concentration of 50 ppm reduced the number of bacteria in the food from 5 to 2log cfu/g after storage for 3 d. An unmeasurable level of the bacterium in the food was observed at days 2 and 3 of storage when 100 and 150 ppm of basil oil was used, respectively. Sensory evaluation suggested that the addition of 100 but not of 150 ppm to nham would be acceptable to consumers. The results from this study confirm the potential use of basil oil as an antimicrobial agent to control S. Enteritidis in food.

Recto-vaginal/urethral fistula: Repair with gracilis muscle transposition  

Directory of Open Access Journals (Sweden)

Full Text Available This study was designed to assess the efficacy of gracilis muscle transposition in repairing rectovaginal and rectourethral fistula. All patients had fecal diversion as a preliminary or concurrent step to fistula repair. Success was defined as healed fistula after stoma closure. Results: Six females and four males underwent gracilis muscle transposition from 1999 to 2006. Gracilis muscle transposition is a viable option for repairing fistulas between the urethra, vagina and the rectum, especially after failed perineal or trans-anal repair. It is associated with low morbidity and good success rate. Underlying Crohn’s disease and previous radiation are associated with poor prognosis.

Omental transposition for Alzheimer 's disease.  

UK PubMed Central (United Kingdom)

A patient with Alzheimer's disease of long standing was treated with omental transposition to his brain. The rational for the procedure was to use the omentum to increase cerebral blood flow and to augment cholinergic neurotransmission activity. The patient improved for a year following surgery but after that time slowly began to decline neurologically and cognitively. However, according to Alzheimer's specialists who have followed the patient pre and postoperatively, he still maintains, 2.5 years after surgery, a higher level of performance than expected. There is theoretical and now a clinical suggestion that the omentum might play some role in the treatment of Alzheimer's disease. In view of the devastating nature of the disease, it seems reasonable to suggest that a limited controlled study be carried out to support or negate the benefit of the operation.

Transpositional transgenesis with piggyBac  

Science.gov (United States)

Transposons are mobile genetic elements that are capable of self-directed excision and subsequent reintegration within the host genome. Transposase such as piggyBac, Sleeping Beauty and Tol2 catalyze these reactions and have shown potential as tools for the stable integration of transgenes when used in the binary plasmid mode. Recent modifications to the transposase and/or the terminal repeats of the transposon have increased their integration efficiency and/or specificity. We recently described the development of a piggyBac transposase system, the helper independent, single construct self-inactivating plasmid called GENIE. Here we describe the structure, safety and function of these transpositional vectors and their use in animal transgenesis and cell transfection.

Transpositionally active episomal hAT elements  

Directory of Open Access Journals (Sweden)

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

Levels of antioxidants and nutraceuticals in basil grown in hydroponics and soil  

UK PubMed Central (United Kingdom)

Owing to the traditional phytotherapeutic use of basil and its importance as a basic component of the Mediterranean diet, this research aimed to study the nutraceutical properties of basil (Ocimum basilicum cv. Genova) grown in hydroponics in comparison with that grown in soil. The antioxidant activities of aqueous and lipid extracts of basil leaves were evaluated both by spectrophotometric detection with the 2,2?-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) radical cation (ABTS? ) and by electron paramagnetic resonance (EPR) detection with the stable radicals peroxylamine disulphonate (Fremy's salt, hydrophilic) and 1,1-diphenyl-2-picrylhydrazyl (DPPH , lipophilic). From EPR decay kinetics analysis, it was possible to distinguish (in the lipid extract) a fast rate constant and a slow rate constant, likely attributable to two different kinds of lipophilic antioxidants. Hydroponic cultivation improved antioxidant activity of both aqueous and lipid extracts, increasing the contents of vitamin C, vitamin E, lipoic acid, total phenols and rosmarinic acid.

Changes in nitrate and nitrite concentrations over 24h for sweet basil and scallions.  

Science.gov (United States)

Nitrate and nitrite concentrations were determined for sweet basil and scallions over 24h to determine if time of sampling or harvest impacts concentrations in raw vegetables. Also, nitrate and nitrite concentrations were determined separately for various edible parts of these plants. Basil had significant changes in nitrate and nitrite concentrations over a 24h period. Nitrate was correlated to changes in light intensity with a 3h lag time. The highest nitrate concentrations in basil (2777 ppm) occurred around 3h after the light intensity peaked and had low values (165-574 ppm) during the dark period. The scallion nitrate and nitrite concentrations were always low but nitrate showed a peak a few hours before sunrise. Nitrate and nitrite concentrations in some raw vegetables may be reduced by harvesting at the best time of day for each type of plant. Nitrate concentrations were different in the edible plant parts tested. PMID:23122149

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

UK PubMed Central (United Kingdom)

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.

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.

The power of norms in the transposition of EU directives  

Directory of Open Access Journals (Sweden)

Full Text Available Transposition research provides an excellent opportunity to bring new data to bear on two of the most dominant theoretical approaches to European Union studies: rational choice institutionalism and sociological institutionalism. Yet the goal of comparable testing is hampered by the underspecified nature of the sociological perspective. This paper takes some steps towards identifying and operationalising a sociological explanation of the transposition of EU directives. Examining an array of alternatives, we single out an approach that focuses on the transmission of norms as a way to explain transposition delay and content changes, and on persuasion to help explain norm change over time. To probe the validity of our explanation, we apply it to a case study of the transposition of two anti-discrimination directives from 2000 in Slovakia. In short, our paper aims to move forward the search for a testable sociological framework in EU studies, while offering an operational approach to studying the process of transposing EU directives.

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.

Temperature effects on the rate of ty transposition.  

UK PubMed Central (United Kingdom)

An assay has been developed to measure the rate of transposition of the transposable element Ty in Saccharomyces cerevisiae. The assay is based on the altered expression of the glucose-repressible alcohol dehydrogenase gene of yeast upon insertion of a Ty in front of this gene. By this assay the transposition rate of Ty elements was found to increase approximately 100-fold at temperatures lower than 30 degrees C, the optimum growth temperature for Saccharomyces cerevisiae.

Regulation of mariner transposition: the peculiar case of Mos1.  

UK PubMed Central (United Kingdom)

BACKGROUND: Mariner elements represent the most successful family of autonomous DNA transposons, being present in various plant and animal genomes, including humans. The introduction and co-evolution of mariners within host genomes imply a strict regulation of the transposon activity. Biochemical data accumulated during the past decade have led to a convergent picture of the transposition cycle of mariner elements, suggesting that mariner transposition does not rely on host-specific factors. This model does not account for differences of transposition efficiency in human cells between mariners. We thus wondered whether apparent similarities in transposition cycle could hide differences in the intrinsic parameters that control mariner transposition. PRINCIPAL FINDINGS: We find that Mos1 transposase concentrations in excess to the Mos1 ends prevent the paired-end complex assembly. However, we observe that Mos1 transposition is not impaired by transposase high concentration, dismissing the idea that transposase over production plays an obligatory role in the down-regulation of mariner transposition. Our main finding is that the paired-end complex is formed in a cooperative way, regardless of the transposase concentration. We also show that an element framed by two identical ITRs (Inverted Terminal Repeats) is more efficient in driving transposition than an element framed by two different ITRs (i.e. the natural Mos1 copy), the latter being more sensitive to transposase concentration variations. Finally, we show that the current Mos1 ITRs correspond to the ancestral ones. CONCLUSIONS: We provide new insights on intrinsic properties supporting the self-regulation of the Mos1 element. These properties (transposase specific activity, aggregation, ITR sequences, transposase concentration/transposon copy number ratio...) could have played a role in the dynamics of host-genomes invasion by Mos1, accounting (at least in part) for the current low copy number of Mos1 within host genomes.

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.

Systematic ileal transposition in Zucker rats shows advantage for long segment distal transposition.  

UK PubMed Central (United Kingdom)

INTRODUCTION: The possibility of achieving diabetes remission through bariatric surgery has dramatically changed treatment options for this disease. Ileal transposition (IT), specifically designed to provoke diabetes remission, has so far shown great success in rodent studies. However, it remains uncertain which combination of ileal length and origin produces best results. METHODS: Forty male Zucker rats underwent transposition of 25% distal, 50% distal, and 50% proximal ileum or sham surgery. Glucose control, insulin, and glucagon-like peptide (GLP)-1 serum levels were analyzed after 1, 3, and 6 months. Body weight was recorded weekly. RESULTS: In relation to sham-operated animals, the 50% distal IT presented with improved glucose tolerance after 1, 3, and 6 months (2-way analysis of variance [ANOVA]: P < .05, < .0001, and < .0001, respectively). The 25% distal and 50% proximal IT only showed improved glucose control after 3 months, suggesting a fading effect in long-term observation (2-way ANOVA: P < .0001 for both). Glucose-stimulated GLP-1 levels were steadily elevated only in the 2 distal IT groups (Mann-Whitney sham versus 50% distal, P < .01, < .01, and < .05; sham versus 25% distal, P < .01, = .001, < .05 for 1, 3, and 6 months, respectively). IT had no impact on serum insulin levels. CONCLUSION: The current study restates the findings of improved glucose tolerance and GLP-1 stimulation after IT, but is the first to demonstrate a fading glycemic effect in long-term observation. Systematic comparison of length and ileal origin revealed that long and distal transposition delivers best results.

Intrathoracic muscular transposition in chronic tuberculous empyema.  

UK PubMed Central (United Kingdom)

BACKGROUND: The effective management of chronic tuberculous empyema requires an evacuation of pus and a re-expansion of the lung or an obliteration of the empyema space such as closed thoracostomy, decortication, or open window thoracostomy (OWT) followed by intrathoracic muscular transposition (IMT). However, the most effective management of chronic tuberculous empyema is still debatable. METHODS: From June 1999 to July 2010, 18 patients with chronic tuberculous empyema who underwent OWT and/or IMT were enrolled in this study. The causes of empyema, and methods and outcomes of treatment were retrospectively reviewed. The success rate of IMT was investigated to evaluate the efficacy. RESULTS: Mean patient age was 54.3 ± 14.9 years and 16 patients were male. Depending on operative methods, three groups were divided: OWT only (n = 4); two-stage operation as OWT followed by IMT (n = 7); and one-stage operation as OWT with IMT simultaneously (n = 7). Of 14 patients who underwent IMT, 13 patients successfully recovered from empyema and bronchopleural fistula (BPF) (success rate, 92.86%), but one patient developed a secondary bacterial infection. There was no operative mortality. CONCLUSION: This study suggests that IMT may be an effective option to control infection or BPF in chronic tuberculous empyema.

?-Linalool-a marker compound of forged/synthetic sweet basil (Ocimum basilicum L.) essential oils.  

Science.gov (United States)

BACKGROUND: Ocimum basilicum L. (sweet basil) is known to occur as several chemotypes or cultivars that differ in their essential oil composition. The surprising discovery of 3,7-dimethylocta-1,7-dien-3-ol, the rare ? isomer of the well-known monoterpene alcohol ?-linalool (3,7-dimethylocta-1,6-dien-3-ol), in samples of Serbian basil oil provoked an investigation of the origin of ?-linalool in these samples. Three scenarios were considered, namely (a) the existence of a new natural chemotype, (b) an artefactual formation during the isolation procedure and (c) the case of a synthetic/forged oil. RESULTS: Noteworthy amounts (15.1-16.9%) of pure ?-linalool were isolated from a commercial sample of basil oil, and detailed spectral analyses (MS, IR, (1) H and (13) C NMR) unequivocally confirmed its identity. The analysis by GC and GC/MS of an additional 20 samples of different O. basilicum oils commercially available on the Serbian market or isolated from plant material cultivated in Serbia resulted in the identification of 149 compounds. The obtained compositional data were compared using multivariate statistical analysis to reveal the possible existence of a new basil chemotype. CONCLUSION: The results of the chemical and statistical analyses give more pro arguments for the synthetic/forged oil hypothesis and suggest that ?-linalool could be used as a marker compound of such O. basilicum oils. © 2013 Society of Chemical Industry.

Sartorius transposition during inguinal lymphadenectomy for melanoma.  

UK PubMed Central (United Kingdom)

BACKGROUND: Inguinal lymph node dissection (ILND) for melanoma has been associated with high rates of wound complication (WC). Sartorius transposition (ST) is a technique that has been proposed to minimize morbidity. We report the frequency of utilization of ST and associated clinical outcomes in a national sample. MATERIALS AND METHODS: Patients undergoing ILND for melanoma were identified in the American College of Surgeons National Surgical Quality Improvement Program Participant Use File (2005-2011). ST status was determined. Univariate logistic regression analyses were performed. Propensity score matching was used to control for operative time. Conditional logistic regression was used to determine the likelihood of a WC following ST in the matched cohort. RESULTS: Of the 381 patients identified, 13% had a WC. By univariate analysis, increasing body mass index (P = 0.006), diabetes (P = 0.02), and longer operative time (P = 0.005) were associated with WC. Sixty-three patients received a prophylactic ST (16.5%). ST use was significantly associated with deep nodal dissection (P = 0.03) and increased operative time (P < 0.0001) but not with any preoperative risk factors. WC rates were similar between ST and non-ST patients (10% versus 14%, P = 0.39). In the multivariate analysis of patients matched for operative time, ST was the only factor significantly associated with lower WC rate. The WC rate was 23% in non-ST compared with 8% in ST patients (P = 0.05). CONCLUSIONS: Nationally, ST is used infrequently at the time of ILND. Moreover, patients undergoing ST do not appear to be selected based on the patient factors associated with increased risk of WC. Risk factors for wound complication should be considered in the selective use of ST.

Anal transposition without colostomy: functional results and complications.  

UK PubMed Central (United Kingdom)

Rectovestibular fistula (RVF) is the most common form of anorectal anomaly in female infants. In the surgical repair of these malformations, most pediatric surgeons use cutback, fistula transposition with or without colostomy, and lately, posterior anorectoplasty with colostomy. This is a retrospective evaluation of the functional results and complications in 47 patients who underwent fistula transposition without colostomy for the treatment of a RVF. We prefer to perform the operation when the rectovaginal septum is amenable to dissection (width >2 mm). All patients had voluntary bowel movements; 28 (60%) had completely normal bowel habits, 45 (96%) good and only 2 (4%) fair. We did not encounter serious surgical complications such as infection dehiscence, and fistula recurrence. We thus prefer anal transposition without colostomy to other modes of surgical therapy for RVF.

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.

Congenital preduodenal portal vein  

Energy Technology Data Exchange (ETDEWEB)

Congenital preduodenal portal vein, first reported by Knight in 1921, is an extremely rare congenital anomaly in which the portal vein passes anteriorly to the duodenum rather than posteriorly in its normal location. It is of surgical significance because it may cause difficulties in operations involving the gall bladder, biliary duct, or duodenum. Recently, we experienced 2 cases of preduodenal portal vein. One was found during surgical exploration for the diagnosis and correction of malrotation of the bowels and the other in a 3 day-old male newborn associated with dextrocardia, situs inversus, and duodenal obstruction by diaphragm. We report these 2 cases with a review of the literature.

A Coupling Argument for the Random Transposition Walk  

CERN Document Server

This paper explores the mixing time of the random transposition walk on the symmetric group. While it has long been known that this walk mixes in order n*log(n) time, this result has not previously been attained using coupling. A coupling argument showing the correct order mixing time is presented. This is accomplished by first projecting to conjugacy classes, and then using the Bubley-Dyer path coupling construction. In order to obtain appropriate bounds on the time it takes the path coupling to meet, ideas from Schramm's paper "Compositions of Random Transpositions" are used.

Different Points of View Concerning the Didactic Transposition  

Directory of Open Access Journals (Sweden)

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

Enrichment, development, and assessment of Indian basil oil based antiseptic cream formulation utilizing hydrophilic-lipophilic balance approach.  

UK PubMed Central (United Kingdom)

The present work was aimed to develop an antiseptic cream formulation of Indian basil oil utilizing hydrophilic-lipophilic balance approach. In order to determine the required-hydrophilic lipophilic balance (rHLB) of basil oil, emulsions of basil oil were prepared by phase inversion temperature technique using water, Tween 80, and Span 80. Formulated emulsions were assessed for creaming (BE9; 9.8, BE10; 10.2), droplet size (BE18; 3.22?±?0.09? ? m), and turbidity (BE18; 86.12?±?2.1%). To ensure correctness of the applied methodology, rHLB of light liquid paraffin was also determined. After rHLB determination, basil oil creams were prepared with two different combinations of surfactants, namely, GMS?:?Tween 80 (1?:?3.45) and SLS?:?GMS (1?:?3.68), and evaluated for in vitro antimicrobial activity, skin irritation test, viscosity and consistency. The rHLB of basil oil and light liquid paraffin were found to be 13.36?±?0.36 and 11.5?±?0.35, respectively. Viscosity, and consistency parameters of cream was found to be consistent over 90 days. Cream formulations showed net zone of growth inhibition in the range of 5.0-11.3?mm against bacteria and 4.3-7.6?mm against fungi. Primary irritation index was found to be between 0.38 and1.05. Conclusively stable, consistent, non-irritant, enriched antiseptic basil oil cream formulations were developed utilizing HLB approach.

Acute portal vein thrombosis.  

Science.gov (United States)

The findings in acute portal vein thrombosis in a patient with chronic calcific pancreatitis and two episodes of pancreatic surgery are described. The diagnosis was made by ultrasound, which showed a dilated portal vein filled with low-level echoes, surrounding hepatic oedema, hypertrophy of the hepatic artery, splenomegaly, collateral vessels and ascites. This was confirmed by computed tomography. The ultrasonic differences in appearance between acute and chronic portal vein thrombosis are discussed, in the context of portal hypertension. The diagnosis of acute portal vein thrombosis should be considered in patients in the appropriate situation who suffer a sudden clinical deterioration with right upper quadrant or abdominal pain. Ultrasound is recommended as the imaging modality of first choice because of the flexibility of its scanning plane and its real time and Doppler capabilities. Computed tomography is valuable in patients with an ileus or heavy pancreatic calcification and for its ability to demonstrate patent vessels on intravenous injection of contrast medium.

Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL) trial: Analysis of amputation free and overall survival by treatment received.  

UK PubMed Central (United Kingdom)

BACKGROUND: An intention-to-treat analysis of randomized Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL) trial data showed that initial randomization to a bypass surgery (BSX)-first strategy was associated with improvements in subsequent overall survival (OS) and amputation-free survival (AFS) of about 7 and 6 months, respectively. We describe the nature and timing of first, crossover, and reinterventions and examine AFS and OS by first treatment received. We also compare vein with prosthetic BSX and transluminal with subintimal balloon angioplasty (BAP) and examine outcomes from BSX after failed BAP. METHODS: We randomly assigned 452 patients with SLI due to infrainguinal disease in 27 United Kingdom hospitals to a BSX first (n = 228) or a BAP first (n = 224) revascularization strategy. All patients have been monitored for 3 years and more than half for >5 years. We prospectively collected data on every procedure, major amputation, and death. RESULTS: Patients randomized to BAP were more likely to have their assigned treatment first (94% vs 85%, P = .01, chi(2)test). BAP had a higher immediate technical failure rate of 20% vs 2.6% (P = .01, chi(2)test). By 12 weeks after randomization 9 BAP (4%) vs 23 BSX (10%) patients had not undergone revascularization; 3 BAP (1.3%) vs 13 BSX (5.8%) had undergone the opposite treatment first; and 35 BAP (15.6%) and 2 (0.9%) BSX had received the assigned treatment and then undergone the opposite treatment. BSX distal anastomoses were divided approximately equally between the above and below knee popliteal and crural arteries; most originated from the common femoral artery. About 25% of the grafts were prosthetic and >90% of vein BSX used ipsilateral great saphenous vein. Most (80%) BAP patients underwent treatment of the SFA alone (38%) or combined with the popliteal artery (42%) and crural arteries (20%). Outcome of vein BSX was better for AFS (P = 0.003) but not OS (P = 0.38, log-rank tests) than prosthetic BSX. There were no differences in outcome between approximately equal numbers of transluminal and subintimal BAP. AFS (P = 0.006) but not OS (P = 0.06, log rank test) survival was significantly worse after BSX after failed BAP than after BSX as a first revascularization attempt. CONCLUSIONS: BAP was associated with a significantly higher early failure rate than BSX. Most BAP patients ultimately required surgery. BSX outcomes after failed BAP are significantly worse than for BSX performed as a first revascularization attempt. BSX with vein offers the best long term AFS and OS and, overall, BAP appears superior to prosthetic BSX.

Root internalization, transport and in-planta survival of Salmonella enterica serovar Newport in sweet basil.  

Science.gov (United States)

It is now acknowledged that food-borne pathogens present in the irrigation water or soil can become associated with crop plants in the field, penetrate internal plant tissues via the root, translocate and survive inside plants. Only little information is available concerning interaction between enteric pathogens and plants. The present study evaluated the potential for contamination of the aromatic plant, sweet basil during cultivation, by Salmonella enterica serovar Newport. Root internalization was plant-age-dependent, with the highest susceptibility occurring at the beginning of the rapid growth phase of the root. Higher incidence of internalization was detected in vegetative than reproductive plant organs, pointing at bacterial transport in the transpiration stream. Internalized Salmonella survived only basil. PMID:23757144

Effect of Water Stress on Some Morphological and Biochemical Characteristics of Purple Basil (Ocimum basilicum)  

Directory of Open Access Journals (Sweden)

Full Text Available Basil (Ocimum basilicum) is an annual herb plant belonging to the Lamiaceae family that is used as a drug, spice and fresh vegetable. In order to study the effects of different levels of water stress on some morphological and biochemical characteristics of purple basil, a pot experiment was conducted in randomized complete block design with six treatments and three replications in growth chamber. The different levels of water stress were 100 (control or non-stress), 90, 80, 70, 60 and 50% of field capacity. The results of statistical analysis showed that water stress has significant effects on morphological and biochemical characteristics. As the soil water content decreased, the plant height, stem diameter, number and area of leaves, Leaf Area Index (LAI), herb yield and leaf chlorophyll contents (a,b and total chlorophyll) decreased but the amounts of anthocyanin and proline increased.

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.

Effect of the addition of basil essential oil on the degradation of palm olein during repeated deep frying of French fries.  

UK PubMed Central (United Kingdom)

The potential antioxidant power of basil essential oil under frying conditions was explored. Two concentrations (200 or 500 ppm) were added to palm olein (PO) to evaluate their effect on fat oxidation/degradation during repeated frying of French fries at 180 °C. A higher oxidative stability index was detected for PO with basil essential oil at 200 ppm. Both concentrations showed lower p-anisidine values than PO without basil essential oil after 5 d of frying. Addition at 500 ppm resulted in the lowest total polar compounds and free fatty acids contents. Thus, the addition of basil essential oil improved the performance of PO during repeated frying of French fries.

The symbolical investiture of the archbishop Basil of Bulgaria at Melnik  

Directory of Open Access Journals (Sweden)

Full Text Available The heretofore variously explained fresco in the apse of the church at Melnik showing the apostle Peter, a bishop and Christ is now interpreted as the symbolical investiture of archbishop Basil. The interpretation is based on iconography analysis taking into account the other frescoes in the apse as well as on the sources relating to the short-lived union of the Bulgarian (Tirnovo) Archbishopric with Rome. The fresco has been dated between 1204 and 1207. .

Ovarian transposition before pelvic irradiation: Indications and functional outcome.  

UK PubMed Central (United Kingdom)

AIM: To investigate the indications and effectiveness of ovarian transposition before pelvic irradiation. METHODS: This was a retrospective analysis of patients with malignancies who underwent ovarian transposition before pelvic irradiation. The collected data included age of patient, type and stage of cancer, details of irradiation treatment, and clinical and biochemical parameters of ovarian function during the period of follow-up. RESULTS: Fourteen adult and four pediatric patients with different types of cancers underwent ovarian transposition during the study period. The common tumor types for the adult patients were cervical cancer (n?=?4), rectal cancer (n?=?4) and medulloblastoma (n?=?3), and for pediatric patients was medulloblastoma (n?=?2). The mean age for adult patients was 31 years (range, 21-40) and for pediatric patients was 7 years (range, 4-10). Of the adult patients, 10 had adjuvant chemotherapy and four had neoadjuvant chemotherapy added to their radiotherapy program. All pediatric patients received adjuvant chemotherapy. Thirteen of 14 (92.85%) adult patients had normal serum level of follicle-stimulating hormone (FSH; ?12?IU/L) and E2 (>50?pg/mL). Only one patient had premature menopause. All pediatric patients demonstrated a normal serum level of FSH (<12) and E2 for their age at 3 and 6 months after completion of their treatment. The mean follow-up was 42 months (range, 34-50). CONCLUSION: Ovarian transposition is an effective procedure for the preservation of ovarian function. Young patients with non-hormone-dependent pelvic tumors should be offered a laparoscopic ovarian transposition before the start of pelvic radiotherapy.

Inferior alveolar nerve transposition in conjunction with implant placement.  

UK PubMed Central (United Kingdom)

PURPOSE: The aim of this prospective study was to determine the incidence of neurosensory disturbance and the cumulative survival and success rates of ITI solid-screw implants placed in conjunction with an inferior alveolar nerve (IAN) transposition technique. MATERIALS AND METHODS: 46 ITI implants were placed in 15 patients following transposition of the IAN. In 4 patients nerve transpositioning was performed bilaterally, so a total of 19 IAN mobilization surgeries were performed. Neurosensory dysfunction was objectively evaluated by using light touch (LT), pain (PT), and 2-point discrimination (2-DT) tests. In addition, patients were asked to answer a short questionnaire to investigate individual feelings of discomfort and advantages related to this surgical technique. The mean follow-up period was 49.1 months (range, 12 to 78 months). RESULTS: The cumulative implant survival and success rates were 95.7% and 90.5%, respectively. Only 2 implants were lost. Neurosensory disturbance (ie, disturbance registered by the LT, PT, and 2-DT tests) was experienced in 4 of 19 cases. However, at the time of data analysis (12 to 78 months after surgery), all patients indicated that they would go through the surgery again. DISCUSSION: The IAN transposition technique, when used in the severely atrophied posterior mandible, allowed placement of implants with adequate length and good initial stabilization. All patients felt that they had received significant benefits from their new prostheses. CONCLUSION: Based on the results of the present study, it can be concluded that lateral nerve transposition can be used as a surgical procedure to enable ITI implant placement in the severely resorbed posterior mandible.

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

UK PubMed Central (United Kingdom)

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.

Fusarium wilt and crown rot of sweet basil: involvement of soilborne and airborne inoculum.  

UK PubMed Central (United Kingdom)

Fusarium oxysporum f. sp. basilici causes wilt and crown and root rot in sweet basil (Ocimum basilicum) in all basil-growing regions of Israel. Wilting and death of basil plants were recorded, and isolates of F. oxysporum were obtained at high frequency from roots and all above ground parts of diseased plants. Inoculation tests with representative isolates verified that the causal agent is F. oxysporum f. sp. basilici. F. oxysporum f. sp. basilici causes both wilt and crown and root rot. The following symptoms were observed: wilt of plants al all stages of growth, brown and black discoloration of roots and lower stems, continuous and discontinuous black lesions on stems, blackening and drying of vegetative apices, growth retardation, and xylem discoloration. The stems were frequently covered with a pink-orange layer consisting mainly of macroconidia, which could become airborne, as revealed by propagule trapping. Therefore, the pathogen has characteristics of both soilborne and airborne pathogens. F. oxysporum f. sp. basilici was readily recovered from structures inside the greenhouse, including concrete stumps, strings, pipes, and walls. Seeds collected from diseased plants were infested with the pathogen and produced diseased plants bearing infested seeds. Because the pathogen is easily disseminated, a holistic approach is necessary to control it. Because of the variety of symptoms associated with this disease, we suggest renaming it "Fusarium wilt and crown rot."

Bilateral parotid duct transposition for keratoconjunctivitis sicca in a Connemara stallion.  

UK PubMed Central (United Kingdom)

A 7-year-old Connemara stallion was presented with a 4 month history of blepharospasm, recurrent corneal ulcerations, mucopurulent ocular discharge, and keratoconjunctivitis sicca (KCS) in both eyes unresponsive to medical therapy. Ophthalmic examination revealed lackluster corneas, axial corneal scarring and pigmentation with associated neovascularization, and absolute KCS in both eyes. Computed tomography scan and endoscopic evaluation of the upper airway and guttural pouches revealed no structural abnormalities to indicate neurogenic KCS. The stallion was diagnosed with immune-mediated dacryoadenitis as all other causes of KCS were excluded. Parotid duct transposition (PDT) was performed in the right eye followed by PDT in the left eye 4 weeks later. The right PDT was functional 2 years post-operatively with significant improvement in ocular comfort and reduced corneal fibrosis and neovascularization. The left PDT developed a salivary-cutaneous fistula over the left masseter muscle post-operatively due to avascular necrosis of the distal parotid duct (PD). Surgical reconstruction of the PDT using an expanded-polytetrafluoroethylene (e-PTFE) tube graft, an e-PTFE tube graft to autogenous caudal auricular vein graft, and an autogenous saphenous vein graft were all unsuccessful. Tear production in the left eye improved at 1 year post-surgery as a result of long term lacrostimulant therapy, and a permanent PD-cutaneous fistula was performed on the left PD at the level of the ventral mandible. Bilateral PDT in the horse is effective in resolving clinical signs associated with KCS; however, morbidity associated with avascular necrosis of the transposed PD may be significant and can result in surgical failure.

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.

Varicose vein surgery.  

UK PubMed Central (United Kingdom)

Venous diseases are common in the general population. After a comprehensive diagnostic evaluation, an individual therapeutic approach should be selected on the basis of the findings, with the aim of treating the diseased vein segments and improving quality of life. Numerous therapeutic options are available for the treatment of varicose veins. In addition to conservative methods such as compression therapy, exercise or drugs, surgical procedures such as traditional surgery, thermal ablation techniques or sclerotherapy can be performed. Recent developments include the use of endoluminal water vapor or mechano-chemical endovenous ablation.

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

UK PubMed Central (United Kingdom)

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.

Matrix-derived combination effect and risk assessment of estragole from basil-containing Plant Food Supplements (PFS).  

UK PubMed Central (United Kingdom)

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.

Preoperative assessment of alternative veins.  

UK PubMed Central (United Kingdom)

Duplex ultrasonography, with or without color flow, has replaced phlebography as the technique of choice to select veins for autogenous bypass grafts. Although anatomic location and length are well-defined by ultrasound, evaluation of the venous wall itself is still imperfect. In situ diameters are less than those of arterialized veins. Ultrasonic search is most valuable in the examination of patients with good veins obscured by a layer of fat. Preoperative knowledge of variant anatomy and location of major veins and their branches facilitates bypass surgery. The preoperative vein mapping should be available in the operating room to guide the placement of incisions for unroofing and exploration directly over veins and vein segments that have a high likelihood of being usable. The finding of a useful vein when none is apparent on physical examination may enable the construction of an autogenous bypass in lieu of a less desirable prosthetic graft or leg amputation.

Postpartum ovarian vein thrombosis.  

UK PubMed Central (United Kingdom)

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.

[From the mechanisms of genetic transposition to the functional genomics  

UK PubMed Central (United Kingdom)

Pioneer works on studying molecular mechanisms of mutagenesis were published in the journal Genetika in the 1960s. In the laboratory of S.I. Alikhanian, studies on molecular mechanisms of genetic transposition were initiated in the late 1960s on the model of bacteriophage transposon Mu (Mutator). Parallel to these studies conducted in the laboratory of plant molecular genetics (Institute of Molecular Genetics, Academy of Sciences of the USSR), which was later named the Laboratory of Functional Genomics (Vavilov Institute of General Genetics, Russian Academy of Sciences), studies on transposition of Ti-plasmid T-DNA of Agrobacterium tumefaciens and works on construction of transgenic plants began in this laboratory. Transgenic plants with the expressed bacterial genes provided a model for the functional genomics. This topic is considered here in detail.

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.

Congenital mitral valve anomalies in transposition of the great arteries.  

UK PubMed Central (United Kingdom)

In 165 hearts in transposition of the great arteries, including 16 with a ventricular septal defect and overriding pulmonary trunk and 5 with a so-called posterior transposition, the left ventricle was studied with emphasis on the morphology of the mitral valve. Distinct mitral valve anomalies were found in 36 cases (22 percent), and four categories of anomalies could be identified. Group A included 16 specimens with a cleft anterior mitral valve leaflet. The cleft was complete or partial. Partial clefts continued as a fibrous cord within the leaflet. In eight cases the cleft was situated posterior or lateral to the pulmonary ostium; in these cases the left ventricular outflow tract was not narrowed. Severe outflow tract stenosis was present in another eight cases in which the cleft was located anterior to the pulmonary ostium, usually in combination with a ventricular septal defect, and in four of these specimens there was straddling of the mitral valve. Group B included eight hearts with an abnormal size or position of the mitral valve, or both, the valve being hypoplastic or rotated clockwise, or both. Group C comprised seven hearts showing redundant left ventricular structures involving the mitral valve, among which were anomalous tissue strands, subpulmonary rings and redundant valve tissue. Group D included five specimens with deficient papillary muscles. It is concluded that an abnormal mitral valve is not unusual in hearts with transposition of the great arteries. The findings are notably important for those patients for whom anatomic surgical correction of the transposition is considered. In comparison with the venous baffle procedure, this operation makes greater demands on the structure of the mitral valve because the pressure in the left ventricle remains at systemic level. Thorough investigation of mitral valve anatomy and function is necessary before anatomic correction is considered.

Collateral veins in left renal vein stenosis demonstrated via CT  

Energy Technology Data Exchange (ETDEWEB)

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.

Ordered DNA release and target capture in RAG transposition.  

Science.gov (United States)

Following V(D)J cleavage, the newly liberated DNA signal ends can be either fused together into a signal joint or used as donor DNA in RAG-mediated transposition. We find that both V(D)J cleavage and release of flanking coding DNA occur before the target capture step of transposition can proceed; no coding DNA is ever detected in the target capture complex. Separately from its role in V(D)J cleavage, the DDE motif of the RAG1/2 active site is specifically required for target DNA capture. The requirement for cleavage and release of coding DNA prior to either physical target binding or functional target commitment suggests that the RAG1/2 transposase contains a single binding site for non-RSS DNA that can accommodate either target DNA or coding DNA, but not both together. Perhaps the presence of coding DNA may aid in preventing transpositional resolution of V(D)J recombination intermediates. PMID:14988730

Lateral thyrotomy with strap muscle transposition for Teflon granuloma.  

UK PubMed Central (United Kingdom)

Lateral thyrotomy and strap muscle transposition have been used independently before. However, the published literature does not record the coordinated use of both procedures in the treatment of Teflon granuloma. In this paper, we present a case of vocal fold paralysis that had been treated successfully by Teflon injection in 1999. Two years later, however, the patient developed a host of symptoms that included a husky voice, shortness of breath and suffocation, which indicated Teflon granuloma. He underwent surgery to excise the Teflon granuloma via a lateral thyrotomy. The affected paraglottic space was then reconstructed using strap muscle transposition. One year postoperatively, the glottis had closed completely on phonation, and the voice retained a moderate roughness due to a scarring change from the earlier Teflon reaction. The patient had no problems with aspiration or shortness of breath during speaking. Our experience indicates that a physician can remove the entire granuloma and create a smooth, straight vibratory surface with complete glottic closure during phonation by using a combination of lateral thyrotomy and strap muscle transposition.

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.

Enrichment, development, and assessment of Indian basil oil based antiseptic cream formulation utilizing hydrophilic-lipophilic balance approach.  

Science.gov (United States)

The present work was aimed to develop an antiseptic cream formulation of Indian basil oil utilizing hydrophilic-lipophilic balance approach. In order to determine the required-hydrophilic lipophilic balance (rHLB) of basil oil, emulsions of basil oil were prepared by phase inversion temperature technique using water, Tween 80, and Span 80. Formulated emulsions were assessed for creaming (BE9; 9.8, BE10; 10.2), droplet size (BE18; 3.22?±?0.09? ? m), and turbidity (BE18; 86.12?±?2.1%). To ensure correctness of the applied methodology, rHLB of light liquid paraffin was also determined. After rHLB determination, basil oil creams were prepared with two different combinations of surfactants, namely, GMS?:?Tween 80 (1?:?3.45) and SLS?:?GMS (1?:?3.68), and evaluated for in vitro antimicrobial activity, skin irritation test, viscosity and consistency. The rHLB of basil oil and light liquid paraffin were found to be 13.36?±?0.36 and 11.5?±?0.35, respectively. Viscosity, and consistency parameters of cream was found to be consistent over 90 days. Cream formulations showed net zone of growth inhibition in the range of 5.0-11.3?mm against bacteria and 4.3-7.6?mm against fungi. Primary irritation index was found to be between 0.38 and1.05. Conclusively stable, consistent, non-irritant, enriched antiseptic basil oil cream formulations were developed utilizing HLB approach. PMID:23984361

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

Varicosity of the pulmonary veins  

Energy Technology Data Exchange (ETDEWEB)

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.

Occurrence of stem rot of basil, caused by Sclerotinia sclerotiorum, in coastal California.  

UK PubMed Central (United Kingdom)

In January and February 1999, extensive dieback was observed on commercial basil (Ocimum basilicum) being grown in shadecloth greenhouses in coastal California's Salinas Valley. Symptoms were associated with stems that were high in the plant canopy and had cut ends resulting from multiple harvests of the foliage. Stems had brown discoloration extending from the cut ends toward the crown of the plant. Attached petioles and leaves turned brown and wilted. Profuse white mycelia were generally present externally on symptomatic stems, and occasionally large (>5 mm long) black sclerotia were found inside affected stems. In some shade houses approximately 20 to 25% of the plants were diseased. Isolations from mycelia, sclerotia, and symptomatic stems produced colonies of Sclerotinia sclerotiorum. Inocula for pathogenicity tests were produced by growing isolates on potato-dextrose agar, removing the resulting sclerotia, air drying them for 12 h, and placing them onto sterilized sand saturated with sterile distilled water. Sand cultures were incubated at 24 to 26°C in the light. After 4 to 6 weeks, apothecia containing asci with eight uniform ascospores developed from the sclerotia. Apothecial cultures were placed at the base of potted basil plants that had been trimmed to simulate harvest and placed in a humidity chamber. After 4 weeks, stem dieback was observed on test plants and S. sclerotiorum was recovered from symptomatic tissue. This pathogenicity test was repeated and the results were similar. Though this disease has occurred in the state prior to 1999, this is the first report of S. sclerotiorum on basil in California. This disease has been reported in North America from Canada and Louisiana (2,3). In contrast with reports from Europe (1), basal infections were not observed in the California greenhouses.

Basil Bunting’s Objectivist Perspective in Poetry and Musical Association  

Directory of Open Access Journals (Sweden)

Full Text Available Basil Bunting, British poet, is one of the rare great modernists who have not been given their due or properly studied. An understanding of his work will help us understand modernism more appropriately. Reference will also be made to opponents who put sight and visuality over and above everything else in man’s effort to acquire knowledge of this world in general. The researchers in this article seek to achieve two goals in this paper. The first or the main goal is to consider the Modern English poet Basil Bunting’s Objectivist roots according to Mitchell’s paper in 2008. The second goal, which naturally emerges from the first one is to present sound play from Bunting’s own view and define them, regarding to Schott’s contributions in 2003, in a part of his long poem, Briggflatts, which lead to the kind of Aural and visual dancing. Then we will conclude , as Bunting mentions more and more, poetry is only its sound. Key words: Bunting; Objectivism; Poetry; Sound; Visuality; Aurality Résumé: Basil Bunting, poète britannique, est l'un des rares grands modernistes qui n'ont pas reçu leur dû ou n'ont pas été bien étudiés. Une bonne compréhension de son travail nous aidera à comprendre le modernisme de façon plus appropriée. Des références seront également faits pour des opposants qui ont mis la vue et la visualité au-delà de tout le reste de l'effort de l'homme d'acquérir des connaissances de ce monde en général. Les chercheurs de cet article visent à atteindre deux objectifs dans le présent document. Le premier ou le principal but est d'examiner les racines objectivistes du poète moderne anglais Basil Bunting selon le document de Mitchell en 2008. Le deuxième objectif, qui découle naturellement du première objectif est de présenter diffuser un show sonore du point de vue personnel de Bunting et les définir, en se référençant aux contributions de Schott en 2003, dans une partie de son poème long, Briggflatts, qui conduit à une sorte de bande sonore et de danse visuelle. Ensuite, nous allons conclure que, comme Bunting mentionne de plus en plus, la poésie est seulement le son. Mots-clés: Bunting; Objectivisme; PoÉSie; Son; VisualitÉ; Auriculaire

Portal vein thrombosis  

Directory of Open Access Journals (Sweden)

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

Cerebral vein thrombosis.  

Science.gov (United States)

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

Pulmonary vein stenosis and the pathophysiology of "upstream" pulmonary veins.  

UK PubMed Central (United Kingdom)

BACKGROUND: Surgical and catheter-based interventions on pulmonary veins are associated with pulmonary vein stenosis (PVS), which can progress diffusely through the "upstream" pulmonary veins. The mechanism has been rarely studied. We used a porcine model of PVS to assess disease progression with emphasis on the potential role of endothelial-mesenchymal transition (EndMT). METHODS: Neonatal piglets underwent bilateral pulmonary vein banding (banded, n = 6) or sham operations (sham, n = 6). Additional piglets underwent identical banding and stent implantation in a single-banded pulmonary vein 3 weeks postbanding (stented, n = 6). At 7 weeks postbanding, hemodynamics and upstream PV pathology were assessed. RESULTS: Banded piglets developed pulmonary hypertension. The upstream pulmonary veins exhibited intimal thickening associated with features of EndMT, including increased transforming growth factor (TGF)-?1 and Smad expression, loss of endothelial and gain of mesenchymal marker expression, and coexpression of endothelial and mesenchymal markers in banded pulmonary vein intimal cells. These immunopathologic changes and a prominent myofibroblast phenotype in the remodeled pulmonary veins were consistently identified in specimens from patients with PVS, in vitro TGF-?1-stimulated cells isolated from piglet and human pulmonary veins, and human umbilical vein endothelial cells. After stent implantation, decompression of a pulmonary vein was associated with reappearance of endothelial marker expression, suggesting the potential for plasticity in the observed pathologic changes, followed by rapid in-stent restenosis. CONCLUSIONS: Neonatal pulmonary vein banding in piglets recapitulates critical aspects of clinical PVS and highlights a pathologic profile consistent with EndMT, supporting the rationale for evaluating therapeutic strategies designed to exploit reversibility of upstream pulmonary vein pathology.

Formation of veins  

International Nuclear Information System (INIS)

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

Pathogenesis of primary varicose veins.  

UK PubMed Central (United Kingdom)

BACKGROUND: Valvular incompetence and reflux are common features of primary varicose veins, and have long been thought to be their cause. Recent evidence, however, suggests that changes in the vein wall may precede valvular dysfunction. METHODS: A literature search was performed using PubMed and Ovid using the keywords 'varicose vein wall changes', 'pathogenesis', 'aetiology' and 'valvular dysfunction'. Articles discussing the pathophysiology of complications of varicose veins, such as ulceration, recurrence, thrombophlebitis and lipodermatosclerosis, were excluded. RESULTS AND CONCLUSION: Positive family history, age, sex and pregnancy are important risk factors for varicose vein formation. Areas of intimal hyperplasia and smooth muscle cell proliferation are often noted in varicose veins, although regions of atrophy are also present. The total elastin content in varicose as opposed to non-varicose veins is reduced; changes in overall collagen content are uncertain. Matrix metalloproteinases (MMPs), including MMP-1, MMP-2, MMP-3, MMP-7 and MMP-9, and tissue inhibitor of metalloproteinase (TIMP) 1 and TIMP-3 are upregulated in varicose veins. Activation of the endothelium stimulates the recruitment of leucocytes and the release of growth factors, leading to smooth muscle cell proliferation and migration. Dysregulated apoptosis has also been demonstrated in varicose veins. An understanding of the pathophysiology of varicose veins is important in the identification of potential therapeutic targets and treatment strategies.

Contribution of major lipophilic antioxidants to the antioxidant activity of basil extracts: an EPR study.  

UK PubMed Central (United Kingdom)

BACKGROUND: The present research analyses the contribution of some lipid antioxidants to the antioxidant activity of lipophilic extracts from basil by an electron paramagnetic resonance (EPR) study using the stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). DPPH assay is considered an easy and accurate method with regard to measuring the antioxidant activity of plant extracts and EPR has already been employed to determine antioxidant activities of lipophilic plant extracts. RESULTS: Lipid extracts were obtained from basil grown hydroponically for 20 or 35 days from sowing and in soil for 35 days from sowing. Fast and slow rate constants were distinguishable in the decay kinetics of DPPH mixture added with lipid extract. Antioxidants with kinetics characterized by a fast decay rate were tocopherols and chlorophylls, whereas those characterized by a slow decay rate were carotenoids, among which were ?-carotene, lutein, ?-apo-8'-carotenal and zeaxanthin. The 20-day hydroponically grown sample, which showed higher contents of tocopherol, chlorophyll and carotenoid molecules, was the sample endowed with the higher content of fast lipophilic antioxidants (FLA) and slow lipophilic antioxidants (SLA). CONCLUSION: The three samples showed different compositions of FLA and SLA, giving rise to different decay kinetics. Despite the differences, in all samples tocopherol contributed about 0.3% to the bulk of FLA, whereas the figure for chlorophyll was about 40%, evidencing the relevant but little-studied role of chlorophyll as an antioxidant.

Root internalization, transport and in-planta survival of Salmonella enterica serovar Newport in sweet basil.  

UK PubMed Central (United Kingdom)

It is now acknowledged that food-borne pathogens present in the irrigation water or soil can become associated with crop plants in the field, penetrate internal plant tissues via the root, translocate and survive inside plants. Only little information is available concerning interaction between enteric pathogens and plants. The present study evaluated the potential for contamination of the aromatic plant, sweet basil during cultivation, by Salmonella enterica serovar Newport. Root internalization was plant-age-dependent, with the highest susceptibility occurring at the beginning of the rapid growth phase of the root. Higher incidence of internalization was detected in vegetative than reproductive plant organs, pointing at bacterial transport in the transpiration stream. Internalized Salmonella survived only basil.

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

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 Using Fenugreek, Parsley and Sweet Basil Seeds as Feed Additives on the Performance of Broiler Chickens  

Directory of Open Access Journals (Sweden)

Full Text Available A research study was conducted to find the effect of Fenugreek (Trigonella Foenum-Graecum L.), parsley (Petroselium sativam L.) and Sweet Basil (Ocimum basilicum L.) seeds as natural feed additives on broiler performance. A total of 120 day-old chicks were reared for 42 days. Feed and water were provided ad libitum. Chicks were divided into four treatments (30 birds each). Each treatment contained three replicates of 10 birds. Each treatment was fed on one of the following experimental diets:1) Control diets (without supplementation). 2) Control diets supplied with Fenugreek at 3 g/kg of the diet. 3) Control diets supplied with parsley at 3 g/kg of the diet. 4) Control diets supplied with Basil at 3 g/kg of the diet. Chicks fed basil diets had significantly (p<0.05) heaviest body weight than those fed the control and fenugreek diets. Carcass characteristics had no significant differences. Significant reduction occurred in serum cholesterol as compared to control diets. It would suggested that the supplementation of broiler chicks diets with (3 g/kg) basil or parsley seeds improved productive performance.

Induction of single transpositions of mobile genetic elements in Drosophila melanogaster using mitomycin C  

International Nuclear Information System (INIS)

Injection of mitomycin C intra-abdominally into males of stable laboratory lines of Drosophila melanogaster causes the appearance of various mutational events at a number of loci of the X-chromosome in offspring. It is shown that they are the result of transpositions of mobile genetic elements. These events are single and are not the result of transposition bursts.

Midterm results after arterial switch operation for transposition of the great arteries: a single centre experience  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The arterial switch operation (ASO) has become the surgical approach of choice for d-transposition of the great arteries (d-TGA). There is, however an increased incidence of midterm and longterm adverse sequelae in some survivors. In order to evaluate operative risk and midterm outcome in this population, we reviewed patients who underwent ASO for TGA at our centre. Methods In this retrospective study 52 consecutive patients with TGA who underwent ASO between 04/1991 and 12/1999 were included. To analyze the predictors for mortality and adverse events (coronary stenoses, distortion of the pulmonary arteries, dilatation of the neoaortic root, and aortic regurgitation), a multivariate analysis was performed. The follow-up time was ranged from 1–10?years (mean 5?years, cumulative 260 patient-years). Results All over mortality rate was 15.4% and was only observed in the early postoperative period till 1994. The predictors for poor operative survival were low APGAR-score, older age at surgery, and necessity of associated surgical procedures. Late re-operations were necessary in 6 patients (13.6%) and included a pulmonary artery patch enlargement due to supravalvular stenosis (n?=?3), coronary revascularisation due to coronary stenosis in a coronary anatomy type E, aortic valve replacement due to neoaortic valve regurgitation (n?=?2), and patch-plasty of a pulmonary vein due to obstruction (n?=?1). The dilatation of neoaortic root was not observed in the follow up. Conclusions ASO remains the procedure of choice for TGA with acceptable early and late outcome in terms of overall survival and freedom of reoperation. Although ASO is often complex and may be associated with morbidity, most patients survived without major complications even in a small centre.

Central vein stenosis.  

UK PubMed Central (United Kingdom)

Central vein stenosis (CVS) is commonly seen in patients receiving hemodialysis through an arteriovenous access, threatening the usability of arteriovenous access for dialysis. Subclavian and internal jugular catheters are prime reasons for the development of CVS, especially in the setting of long-term use of multiple catheters. CVS related to cardiac rhythm devices also is seen frequently. Idiopathic CVS can be encountered, although it is less common. Clinical features ultimately become sufficiently prominent to prompt angiographic evaluation. CVS should be evaluated carefully because management must be individualized. The primary method for treatment of CVS is endovascular intervention, including angioplasty and stent placement, whereas surgical options should be pursued in only refractory cases due to the invasiveness of the intervention. Early referral of patients for chronic kidney disease care; timely discussion of kidney replacement modality choices, including nonhemodialysis options such as peritoneal dialysis and kidney transplantation; placement of arteriovenous access prior to the onset of dialysis; and avoidance of catheters and other central vein instrumentation will prevent the development of CVS in most patients with kidney disease.

Full Text Available Genótipos de manjericão (Ocimum basilicum L.) apresentam diferentes teores, rendimentos e composições químicas de óleos essenciais. Fatores influenciam na produção do óleo essencial de manjericão, como a cultivar plantada e o método de cultivo. O estudo dos parâmetros genéticos tem sido ferramenta útil na identificação de genótipos superiores. Este trabalho teve o objetivo de estimar alguns parâmetros genéticos associados ao comportamento produtivo de seis populações de manjericão nos anos agrícola 2004/05 e 2005/06. As características massa seca de folha + inflorescência e rendimento de óleo essencial apresentaram grande variabilidade por forte influência dos anos estudados. Já o teor de linalol manteve sua produtividade estável ao longo dos dois anos. Teor e rendimento de óleo essencial e teor de linalol no óleo essencial apresentaram herdabilidades altas na análise conjunta, indicando controle genético e grande possibilidade de serem transmitidas para as gerações futuras. Na análise conjunta as populações PI 197442-S3-bulk 3, PI 197442-S3-bulk 5 e PI 197442-S3-bulk 8 apresentaram os maiores teores e rendimentos de óleo essencial. Quanto ao constituinte químico majoritário do óleo essencial, o linalol, todas as populações apresentaram teores semelhantes, diferindo apenas na presença de alguns constituintes químicos minoritários.Basil (Ocimum basilicum L.) genotypes present different contents, yields and chemical constituents in its essential oils. Factors influence the essential oil production of basil, such as cultivar and cultivation method. The study of genetic parameters is a useful tool to identify superior genotypes. In this work we estimated some genetic parameters associated to the production behavior of six basil populations cultivated in 2004/05 and 2005/06. The variables dry weight of leaves + inflorescences and essential oil yield presented high variability because of strong influence of the studied years. Linalool content presented constant values during the two years. Essential oil content and yield and linalool content in the essential oil presented high herdability in the combined analyses, indicating genetic control and great possibilities to transmit them to the following generations. The combined analyses showed highest essential oil content and yield for the populations PI 197442-S3-bulk 3, PI 197442-S3-bulk 5 and PI 197442-S3-bulk 8. For the major chemical constituent of the essential oil, linalool, all the populations presented similar content. Only the minor chemical constituents were different.

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

Science.gov (United States)

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

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

Effect of the addition of basil essential oil on the degradation of palm olein during repeated deep frying of French fries.  

Science.gov (United States)

The potential antioxidant power of basil essential oil under frying conditions was explored. Two concentrations (200 or 500 ppm) were added to palm olein (PO) to evaluate their effect on fat oxidation/degradation during repeated frying of French fries at 180 °C. A higher oxidative stability index was detected for PO with basil essential oil at 200 ppm. Both concentrations showed lower p-anisidine values than PO without basil essential oil after 5 d of frying. Addition at 500 ppm resulted in the lowest total polar compounds and free fatty acids contents. Thus, the addition of basil essential oil improved the performance of PO during repeated frying of French fries. PMID:23772857

Endovenous removal of dislodged left renal vein stent in a patient with nutcracker syndrome.  

UK PubMed Central (United Kingdom)

Stent migration and dislodgment is a potential complication after endovenous stenting of the left renal vein (LRV) for nutcracker syndrome. Our purpose is to describe the technique for endovenous removal of such a dislodged stent that was used in a 36-year-old woman with nutcracker syndrome initially treated with renal vein transposition. Recurrent renal vein compression and symptoms developed and a 14 × 20-mm self-expanding stent was placed in the LRV and was noted to be dislodged into the inferior vena cava on the first post-procedure day. Through right internal jugular access, the stent was stabilized by cannulating a cell of the stent using a guide wire and an angled angiographic catheter. A 20Fr sheath was then placed via right femoral vein access into the inferior vena cava. The stent lumen was cannulated from femoral approach and the stent straightened with a stiff wire. An 18-mm angioplasty balloon was then used to capture the stent. The stent was then compressed with two 25-mm loop snares while simultaneously deflating the balloon as it was pulled into the 20Fr sheath and removed. The LRV was restented with an 18 × 40-mm self-expanding stent. Stenting of LRV for nutcracker syndrome can result in stent migration. Endovenous removal of such a dislodged self-expanding stent is feasible. Our technique emphasizes stent stabilization with cell cannulation and capture over a larger diameter balloon.

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

Directory of Open Access Journals (Sweden)

Full Text Available The aerial parts essential oils of Ocimum basilicum (Lamiaceae) from Togo were steam-distilled and investigated for their percentage composition (GC and GC/MS) and in vitro antimicrobial activities. Five oil chemotypes were identified and classified as follows in line with their principal components: estragole type; linalool/estragole type; methyleugenol type; methyleugenol/t-anethole type; t-anethole type. The in vitro microbiological experiments revealed that only the methyleugenol and methyleugenol/t-anethole chemotypes were active against tested fungi and bacteria. Their minimum inhibitory concentrations (MIC) ranged from 80 to 150 µl.l-1 and from 200 to 500 µl.l-1 respectively. Likewise, on tested bacteria the MIC varied from 200 µl.l-1 to 400 µl.l-1 and from 250 to 500 µl.l-1 respectively. These findings are supportive of the potential of both basil oil chemotypes for use as active ingredients in natural antibiotic drugs.

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

UK PubMed Central (United Kingdom)

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.

A truncated form of the bacteriophage Mu B protein promotes conservative integration, but not replicative transposition, of Mu DNA.  

UK PubMed Central (United Kingdom)

The phage-encoded proteins required for conservative integration of infecting bacteriophage Mu DNA were investigated. Our findings show that functional gpA, an essential component of the phage transposition system, is required for integration. The Mu B protein, which greatly enhances replicative transposition of Mu DNA, is also required. Furthermore, a truncated form of gpB lacking 18 amino acids from the carboxy terminus is blocked in replicative transposition, but not conservative integration. Our results point to a more prominent role for gpB than simply a replication enhancer in Mu DNA transposition. The ability of a truncated form of B to function in conservative integration, but not replicative transposition, also suggests a key role for the carboxy-terminal domain of the protein in the replicative reaction. The existence of a shortened form of gpB, which uncouples conservative integration from replicative transposition, should be invaluable for future dissection of Mu DNA transposition.

BACKGROUND: An intention-to-treat analysis of the Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL) trial showed that in patients with severe lower limb ischemia (SLI) due to infrainguinal disease who survived for 2 years after intervention, initial randomization to a bypass surgery (BSX)-first vs balloon angioplasty (BAP)-first revascularization strategy was associated with improvements in subsequent overall survival (OS) and amputation-free survival (AFS) of about 7 and 6 months, respectively. This study explored the value of baseline factors to estimate the likelihood of survival to 2 years for the trial cohort (Cox model) and for individual BASIL trial patients (Weibull model) as an aid to clinical decision making. METHODS: Of 452 patients presenting to 27 United Kingdom hospitals, 228 were randomly assigned to a BSX-first and 224 to a BAP-first revascularization strategy. Patients were monitored for at least 3 years. Baseline factors affecting the survival of the entire cohort were examined with a multivariate Cox model. The chances of survival at 1 and 2 years for patients with given baseline characteristics were estimated with a Weibull parametric model. RESULTS: At the end of follow-up, 172 patients (38%) were alive without major limb amputation of the trial leg, and 202 (45%) were alive. Baseline factors that were significant in the Cox model were BASIL randomization stratification group, below knee Bollinger angiogram score, body mass index, age, diabetes, creatinine level, and smoking status. Using these factors to define five equally sized groups, we identified patients with 2-year survival rates of 50% to 90%. The factors that contributed to the Weibull predictive model were age, presence of tissue loss, serum creatinine, number of ankle pressure measurements detectable, maximum ankle pressure measured, a history of myocardial infarction or angina, a history of stroke or transient ischemia attack, below knee Bollinger angiogram score, body mass index, and smoking status. CONCLUSIONS: Patients in the BASIL trial were at high risk of amputation and death regardless of revascularization strategy. However, baseline factors can be used to stratify those risks. Furthermore, within a parametric Weibull model, certain of these factors can be used to help predict outcomes for individuals. It may thus be possible to define the clinical and anatomic (angiographic) characteristics of SLI patients who are likely-and not likely-to live for >2 years after intervention. Used appropriately in the context of the BASIL trial outcomes, this may aid clinical decision making regarding a BSX- or BAP-first revascularization strategy in SLI patients like those randomized in BASIL.

[One-stage operation for treatment of transposition of penis and scrotum complicated by hypospadia  

UK PubMed Central (United Kingdom)

Transposition of penis and scrotum is often complicated by hypospadia and used to be corrected by staged operation. Since 1984 a new procedure has been developed in which the transposition of penis and scrotum and clubbed penis were corrected, and urethroplasty was performed at same time. Six children received this operation uneventfully. Postoperative follow-up revealed that normal penis position, erection and urination were achieved in these patients. This operation is applicable to patients with transposition of penis and scrotum complicated by various hypospadia. The operative method and key to ensure success are described in this article.

PlayDT : 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.

Transposase concentration controls transposition activity: Myth or reality?  

Science.gov (United States)

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

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.

Stomatal density and metabolic determinants mediate salt stress adaptation and water use efficiency in basil (Ocimum basilicum L.).  

UK PubMed Central (United Kingdom)

Increasing salinity tolerance and water-use efficiency in crop plants are two major challenges that agriculture must face in the next decades. Many physiological mechanisms and molecular components mediating crop response to environmental stresses have been identified. However, the functional inter-links between stress adaptation responses have not been completely understood. Using two basil cultivars (Napoletano and Genovese) with contrasting ability to respond to salt stress, here we demonstrate that reduced stomatal density, high ascorbate level and polyphenol oxidase (PPO) activity coordinately contribute to improve basil adaptation and water use efficiency (WUE) in saline environment. The constitutively reduced stomatal density was associated with a "delayed" accumulation of stress molecules (and growth inhibiting signals) such as abscisic acid (ABA) and proline, in the more tolerant Genovese. Leaf volatile profiling also revealed cultivar-specific patterns, which may suggest a role for the volatile phenylpropanoid eugenol and monoterpenes in conferring stress tolerance via antioxidant and signalling functions.

Effect of Storage on Physico-Chemical, Microbiological and Sensory Quality of Bottlegourd-Basil Leaves Juice  

Directory of Open Access Journals (Sweden)

Full Text Available Bottlegourd (Lagenaria siceraria) and Basil (Ocimum sanctum) leaves blended juice was formulated with the help of Response surface methodology. The central composite design with 15 experimental combinations was used to optimize the product. The surface plots are used to represent the effects of variations in the ingredient levels. The physico-chemical, microbiological safety and sensory characteristics of the bottlegourd-basil blended juice in glass bottle were evaluated during 6 months at room temperature (28+2°C). There were no remarkable changes in pH, total soluble solids, total acidity (as citric acid) and sensory scores of the juice during storage. Loss of vitamin C and ?-carotene were 74 and 57%, respectively after 6 months of storage. The result revealed that the blended juice was acceptable for 6 months and was microbiologically safe.

Unexpectedly rapid IS1 transposition into an Arabidopsis chromatin remodeling gene.  

UK PubMed Central (United Kingdom)

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

Ultrastructure of popliteal vein aneurysm.  

UK PubMed Central (United Kingdom)

The term aneurysm is used to indicate a permanent and irreversible localized vascular dilatation that involves all three layers of the blood vessel wall. It may develop in any part of the circulatory system, including veins, and its history, presentation, and management differ depending on the location. A venous aneurysm is defined as a solitary area of fusiform or saccular dilatation occurring in the course of a major vein or connected by a single channel to a major venous structure. The lower extremities are the most frequently affected, with the popliteal vein being the most common site. Although different theories have been advanced, the etiology of the disease remains uncertain. Mechanical stress and/or degenerative changes within the vein wall are believed to represent the most likely causes of venous aneurysm. To date, there are only a few publications dealing with the histological appearance of popliteal vein aneurysm, and no studies that specifically describe its ultrastructural details have been published to our knowledge. In an attempt to fill this gap and to provide better insights into the pathophysiological mechanisms possibly involved in aneurysmal venous disease, we describe the fine structure of popliteal vein wall and valve in health and disease using both scanning and transmission electron microscopy.

First Report of Leaf Spot Caused by Corynespora cassiicola on Basil (Ocimum basilicum) in Italy  

UK PubMed Central (United Kingdom)

Sweet basil (Ocimum basilicum) is an economically important herb in several Mediterranean countries. Approximately 80 ha are grown annually in Italy for fresh consumption and processing. In 2006, a damaging foliar disease of sweet basil cv. Genovese gigante was observed in several greenhouses located in the Liguria Region of northern Italy. A disease incidence of more than 50% was observed. Leaves of infected plants initially showed dark brown-to-black, 1 to 3 × 1.5 to 5.3 mm in diameter, circular spots surrounded by a chlorotic halo. Within 2 to 3 days, the spots coalesced, leading to extensive leaf necrosis with occasional shot holes. Stem lesions were brown, elongated, and irregularly dispersed. Although the distribution of the disease generally became uniform, it usually appeared originally in a patchy pattern at the central areas of the greenhouses, where temperatures and relative humidity were highest. Basal leaves were most severely affected by the disease when air circulation was apparently poor. Microscopic observations revealed light brown conidiophores, ending in sterigmata with conidia borne singly or in chains. Conidia were 31.9 to 212.2 ?m (average 68.1 ?m) long and 4.3 to 11.6 ?m (average 7.8 ?m) wide, with longitudinal cross walls. Such morphology is typical of Corynespora cassiicola (3). The fungus was consistently isolated from symptomatic leaves onto potato dextrose agar. The ITS region (internal transcribed spacer) of rDNA was amplified using primers ITS4/ITS6 and sequenced. BLASTn analysis (1) of the 215 bp obtained showed an E-value of 0.0 with C. cassiicola and the nucleotide sequence has been assigned GenBank Accession No. EF 545008. Pathogenicity tests were performed by spraying leaves of 10 healthy 30-day-old potted O. basilicum plants cv. Genovese gigante with a 105 conidia per ml aqueous suspension. Plants in 10 pots sprayed with water only served as controls. Plants were covered with plastic bags for 24 h after inoculation and maintained at 20 to 25°C. The first foliar lesions developed on leaves 3 to 4 days after inoculation, whereas control plants remained healthy. C. cassiicola was consistently reisolated from these lesions. The pathogenicity test was completed twice. To our knowledge, this is the first report of C. cassiicola on O. basilicum in Italy. Other previous records of this disease were from India (2) and Brunei (4).

[Open window thoracostomy and muscle flap transposition for thoracic empyema  

UK PubMed Central (United Kingdom)

Open window thoracostomy for thoracic empyema: Open window thoracostomy is a simple, certain and final drainage procedure for thoracic empyema. It is most useful to drain purulent effusion from empyema space, especially for cases with broncho-pleural fistulas, and to clean up purulent necrotic debris on surface of empyema sac. For changing of packing gauzes in empyema space through a window once or twice every day after this procedure, thoracostomy will have to be made on the suitable position to empyema space. Usually skin incision will be layed along the costal bone just at the most expanded position of empyema. Following muscle splitting to thoracic wall, a costal bone just under the incision will be removed as 8-10 cm as long, and opened the empyema space through a costal bed. After the extension of empyema space will be preliminarily examined through a primary window by a finger or a long forceps, it will be decided costal bones must be removed how many (usually 2 or 3 totally) and how long (6-8 cm) to make a window up to 5 cm in diameter. Thickened empyema wall will be cut out just according to a window size, and finally skin edge and empyema wall will be sutured roughly along circular edge. Muscle flap transposition for empyema space: Pediclued muscle flap transposition is one of space-reducing operations for (chronic) empyema Usually this will be co-performed with other several procedures as curettages on empyema surface, closure of bronchopleural fistula and thoracoplasty. This is radically curable for primarily non fistulous empyema or secondarily empyema after open window thoracostomy done for fistula. Furthermore this is less invasive than other radical operations as like pleuro-pneumonectomy, decortication or air-plombage for empyema. There are 2 important points to do this technique. One is a volume of muscle flap and another is good blood flow in flap. The former suitable muscle volume is need to impact empyema space or to close fistula, and the latter over-elongation and bending of pedicles should be avoided. Actually, after removing several costal bones on the empyema space, empyema wall will be incised for about 2/3 of total empyema length along costal beds. Then muscle flap will be introduced into cleaned up space and sutured on empyema surface at several points. It is better to lay small vacuum drain tubes along flap within empyema space.

A diallel study of yield components and essential oil constituents in basil (Ocimum basilicum L.)  

UK PubMed Central (United Kingdom)

This study aimed to estimate the general and specific combining abilities of basil by analyzing its essential oil content and main chemical compounds. The study was conducted at the “Campus Rural da UFS” Research Station, located in São Cristóvão, Sergipe. Four cultivars with different chemical compositions were selected and diallel crosses were performed. The F1 seeds and the parents were planted in a randomized block design in triplicate. Data were evaluated using Griffing's diallel analysis, model 2, and the means were grouped by the Skott–Knott test (p?0.05). Plant height, crown diameter, leaf length, leaf width, leaf dry weight, essential oil content and yield, and chemical constituent content were recorded and examined. Analysis of variance for combining ability indicated that the effects of the General Combining Ability (GCA) showed significant differences and the effects of the Specific Combining Ability (SCA) in crosses were significant, except for the length and width of leaves. For almost all the features tested, both additive and nonadditive effects influenced the hybrids’ performance.

Transposition of the EU cogeneration directive: A vision for Portugal  

International Nuclear Information System (INIS)

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

Transporting newborns with transposition of the great arteries.  

UK PubMed Central (United Kingdom)

AIMS: The aim of the study was to examine the prevalence and management of outborn babies with a post-natally confirmed diagnosis of transposition of the great arteries (TGA) requiring transport by the Newborn and Paediatric Emergency Transport Service (NETS), New South Wales during the epoch 1991-2010. METHOD: A retrospective audit of NETS database and case notes. The physiological status, interventions and any complications encountered from the point of referral to NETS (pre-transport), stabilisation (transport) and subsequent admission to the receiving hospital (post-transport) were evaluated. RESULTS: One hundred fifty-seven infants with TGA were transported, with an average of eight per year (1:11,598 births). Seven (4%) had an antenatal diagnosis, and 72 (46%) had a post-natal diagnosis prior to referral. Physiological and clinical parameters demonstrated overall clinical stability; however, 47% of the babies had a PaO(2) <30 mmHg, and approximately one-fifth had oxygen saturations <70%. Rates of mechanical ventilation and prostaglandin E(1) administration were approximately 50%. A quarter of transported babies encountered a transport-related event, including one death and two babies for which a decision was reached to forego life-sustaining treatment at the referring hospital. CONCLUSIONS: Most newborns with TGA remain stable or improve during transport. There is a rate of adverse events; however, this reinforces the need to facilitate delivery where there is ready access to interventional paediatric cardiology services.

Efficient transposition of IS204-derived plasmids in Streptomyces coelicolor.  

UK PubMed Central (United Kingdom)

In order to study functional gene expression in Streptomyces coelicolor, a mini-transposon encoding the apramycin resistance gene aac(3)IV within its inverted repeat (IR) boundaries was constructed based on IS204, which was previously identified in the genome of Nocardia asteroides YP21. The mini-transposon and IS204 transposase gene were then put on a kanamycin-resistant conjugative plasmid pDZY101 that can only replicate in Escherichia coli. After mating with S. coelicolor A3(2) M145, resistant colonies arose efficiently on both apramycin and kanamycin plates. Plasmid rescue indicated that entire plasmids were inserted into the M145 genome with cleavage at an inverted repeat junction formed by the right inverted repeat (IRR) and the last 18bp of the transposase gene, while the left inverted repeat (IRL) was untouched. Southern blot analysis of the mutants using an aac(3)IV gene probe showed that transposition of plasmid pDZY101 was genetically stable, with a single-copy insertion within the S. coelicolor M145 genome. Several mutagenesis libraries of S. coelicolor M145 were constructed using plasmid pDZY101 derivatives and the transposon insertion site was determined. The correlation between novel mutant phenotypes and previously uncharacterized genes was established and these transposon locations were widely scattered around the genome.

Congenitally corrected transposition in the adult: detection by radionuclide angiocardiography  

Energy Technology Data Exchange (ETDEWEB)

Congenitally corrected transposition (CCT) of the great vessels is an uncommon anomaly usually detected in children because of associated severe cardiac malformations. When these are absent, patients may be hemodynamically normal, but associated cardiac abnormalities are usually present in CCT, leading to symptoms in adulthood.

Subfascial endoscopic perforator vein surgery.  

Science.gov (United States)

Chronic venous insufficiency is a tremendous health care problem in western societies. Venous disease can affect any combination of the superficial, deep, and perforator venous systems of the lower extremities. Generally the superficial venous deficits are addressed through sclerotherapy, enovenous ablation, stab phlebectomy, and or stripping. Patients with advanced clinical sequelae (lipodermatosclerosis or ulceration) of CVI should also be evaluated for the presence of incompetent perforating veins. Open surgical approached to the calf perforating veins (ie. Linton procedure) were complicated by significant wound complications and have largely been replaced by the less invasive Subfascial Endoscopic Perforator Surgery (SEPS). The use of SEPS in patients with ulceration has been shown to be safe and to reduce the time that patients will have ulcers during follow-up. This chapter will review the pathophysiology, diagnosis, and treatment of incompetent perforating veins of the legs with particular attention to surgical issues. PMID:16387265

Adrenal vein catheterization. Anatomic considerations  

Energy Technology Data Exchange (ETDEWEB)

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.

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  

Directory of Open Access Journals (Sweden)

Full Text Available 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, consorciado 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.Ocimum basilicum L.

[Canine tooth transposition study on a group of patients orthodontically treated].  

UK PubMed Central (United Kingdom)

The dental transposition is an eruption anomaly, which occurs in this process towards the final stage and that represents the switching of 2 teeth that are next to each other. The tooth that most often is involved in transposition is the canine tooth, most frequently the upper one, which switches places either with the first premolar either with the lateral incisor. Under a clinical aspect, the transposition can be total (complete) or partial (incomplete), the latter reported both for crowns and roots. The clinical manifestation of the anomaly imposes the characteristic signs and the individualized therapeutical attitude. The dental transposition must be differentiated within the eruption anomalies from the transmigration, which defines the displacement of a tooth inside the bone beyond the median line, this tooth usually being the lower canine. Our study, which was conducted on a small group of 34 patients, shows the results of the analysis of the anomaly versus the gender, the type of the transposition, the affected maxillary etc.

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.

Congestive index of portal vein  

Energy Technology Data Exchange (ETDEWEB)

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

[Complications in varicose vein operations  

UK PubMed Central (United Kingdom)

Although operations on varicous veins are regarded as easy and low-risk, severe complications with the involvement of arteries, veins and nerves can occur during the course of such operations and, in reconstruction, demand the whole spectrum of vascular surgery. Therefore, surgeons operating on varicous veins and on out-patients should possess sufficient experience in vascular surgery and be able to admit their patients to a centre of vascular surgery in the case of severe complications without unnecessary loss of time. Beside a perfectly done operation sufficient preoperative diagnostic examinations and postoperative care of the patient have to be claimed. The treatment of varicous veins in a hospital must be possible also in the future. The extent of the procedure is usually greater during stationary treatment and bilateral operations are feasible. Therefore, from the economic point of view, a stationary assignment for a few days does not seem more expensive than several single operations with subsequent outpatient treatment and repeated diagnostic examinations in ambulatory settings.

Gene transposition causing natural variation for growth in Arabidopsis thaliana.  

UK PubMed Central (United Kingdom)

A major challenge in biology is to identify molecular polymorphisms responsible for variation in complex traits of evolutionary and agricultural interest. Using the advantages of Arabidopsis thaliana as a model species, we sought to identify new genes and genetic mechanisms underlying natural variation for shoot growth using quantitative genetic strategies. More quantitative trait loci (QTL) still need be resolved to draw a general picture as to how and where in the pathways adaptation is shaping natural variation and the type of molecular variation involved. Phenotypic variation for shoot growth in the Bur-0 x Col-0 recombinant inbred line set was decomposed into several QTLs. Nearly-isogenic lines generated from the residual heterozygosity segregating among lines revealed an even more complex picture, with major variation controlled by opposite linked loci and masked by the segregation bias due to the defective phenotype of SG3 (Shoot Growth-3), as well as epistasis with SG3i (SG3-interactor). Using principally a fine-mapping strategy, we have identified the underlying gene causing phenotypic variation at SG3: At4g30720 codes for a new chloroplast-located protein essential to ensure a correct electron flow through the photosynthetic chain and, hence, photosynthesis efficiency and normal growth. The SG3/SG3i interaction is the result of a structural polymorphism originating from the duplication of the gene followed by divergent paralogue's loss between parental accessions. Species-wide, our results illustrate the very dynamic rate of duplication/transposition, even over short periods of time, resulting in several divergent--but still functional-combinations of alleles fixed in different backgrounds. In predominantly selfing species like Arabidopsis, this variation remains hidden in wild populations but is potentially revealed when divergent individuals outcross. This work highlights the need for improved tools and algorithms to resolve structural variation polymorphisms using high-throughput sequencing, because it remains challenging to distinguish allelic from paralogous variation at this scale.

Antibacterial properties of essential oils and methanol extracts of sweet basil Ocimum basilicum occurring in Bangladesh.  

UK PubMed Central (United Kingdom)

The antibacterial potential of essential oils and methanol extracts of sweet basil Ocimum basilicum L. (Lamiaceae) was evaluated for controlling the growth range of food-borne pathogenic bacteria. Essential oils extracted by hydrodistillation from the leaves and stems were analyzed by GC-MS. Fifty-seven compounds representing 94.9 and 96.1% of the total leaf and stem oils, respectively, were identified, of which methyl chavicol (36.7 and 29.9%), gitoxigenin (9.3 and 10.2%), trimethoquinol (10.3 and 8.4%), beta-guaiene (3.7 and 4.1%), aciphyllene (3.4 and 3.0%), alizarin (3.2 and 4.4%), naphthaline (2.2 and 3.8%), (-)-caryophyllene (2.0 and 1.9%), and mequinol (1.6 and 1.8%) were the major compounds. The essential oils (10 microL/disc of 1:5, v/v dilution with methanol) and methanol extracts (300 microg/disc) of O. basilicum displayed a great potential of antibacterial activity against Bacillius cereus, B. subtilis, B. megaterium, Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, Shigella boydii, S. dysenteriae, Vibrio parahaemolyticus, V. mimicus, and Salmonella typhi with their respective zones of inhibition of 11.2-21.1 mm and MIC values of 62.5-500 microg/mL. The results of this study suggest that the natural products derived from O. basilicum may have potential use in the food and/or pharmaceutical industries as antimicrobial agents.

Rheology and microstructure of basil seed gum and ?-lactoglobulin mixed gels  

UK PubMed Central (United Kingdom)

Gelling profiles and interaction between basil seed gum (BSG) and ?-lactoglobulin (BLG) were characterized using dynamic rheology and scanning electron microscopy. Sequence of experimental sweeps of time–temperature, frequency, and strain were applied for BSG, BLG and BLG–BSG mixtures in the ratio of 10:1, 5:1, 2:1 & 1:2. Rheological behavior of BLG was found to be different from that of BSG and gelling point was raised during the heating period. By increasing BSG concentration, storage and loss moduli were increased and gel point was determined at about 80 °C, which was dependent of concentration and occurred during cooling period. Upon heating–cooling period (temperature sweep) of BLG–BSG mixture from 20 °C to 90 °C and coming back to original temperature, mixed gels presented a biphasic profile: the first phase, characterized by a sharp increase in the storage modulus in which gelation of BLG happened and the second phase exhibiting an increase in the storage modulus, corresponded to the build-up of a BSG network. Strain sweep results obtained for mixed gels at the end of the temperature sweep tests supported the biphasic hypothesis. The SEM results showed that BLG has a globular structure in comparison with BSG which has fibril and globular structure and the mean diameter of its globular structure was higher than that of BLG. Increasing the ratio of BSG to BLG resulted in a finer microstructure, which could retain higher water to form gel. In addition, microstructural study showed that BLG–BSG mixed is a bicontinuous network in which BSG dispersed in BLG continuous phase.

Defective retroviruses can disperse in the human genome by intracellular transposition.  

UK PubMed Central (United Kingdom)

Using an assay for retrotransposition detection (T. Heidmann, O. Heidmann, and J. F. Nicolas, Proc. Natl. Acad. Sci. USA 85:2219-2223, 1988), we demonstrated that a defective retrovirus deleted for the gag, pol, and env open reading frames can disperse in the genome of human HeLa cells by intracellular transposition, at a frequency close to 10(-6) events per cell per generation. Transposition requires cooperation in trans for the gag and pol gene products and may be associated with the release of low amounts of noninfectious retroviruslike particles which are the hallmarks but not the intermediates of this transposition process. Similar events could account for the dispersion at high copy number of some of the human endogenous sequences related to retroviruses and for the occurrence of noninfectious retroviruslike particles in human placenta and several tumor cell lines (reviewed by E. Larsson, N. Kato, and M. Cohen, Curr. Top. Microbiol, Immunol, 148:115-132, 1989).

Congenitally corrected transposition of great arteries with ischemic symptoms in middle age  

International Nuclear Information System (INIS)

[en] Congenitally corrected transposition of great arteries (CCTGA) is a rare congenital disease first described by Von Rokitansky in 1875. Transposition of the great arteries comprises 2.6-7.8% of all cases of congenital heart disease, and if uncorrected, is commonly fatal in first year of life. Patients with corrected transposition of the great arteries without associated defects may remain undiagnosed until adult life. Symptoms occur rarely before the fourth and fifth decades, when rhythm disturbance, left atrioventricular valve regurgitation and moderately impaired systemic ventricular function cause congestive cardiac failure. We report here a case of drug overdose with ischemic symptoms and CCTGA without associated anomalies in a 40-year-old male. (author)

Early treatment of an ectopic premolar to prevent molar-premolar transposition.  

UK PubMed Central (United Kingdom)

Orthodontic treatment is planned on an individual, case-by-case basis after thoroughly considering the patient's overall facial and dental characteristics, the expected duration of treatment, costs, patient preferences, and the orthodontist's experience. This article reports the treatment of a patient with a maxillary premolar-molar transposition in the permanent dentition that was successfully managed with orthodontic treatment. A girl, aged 10 years 2 months, came for treatment with an ectopic maxillary left premolar. Radiographic analysis indicated a developing complete transposition of the maxillary left premolar. The patient was treated with extraction of the deciduous molar and surgical exposure and ligation of the premolar. Eruption was properly guided, and the correct order of the 2 teeth was restored in the arch. This challenging treatment approach is described in detail, including the mechanics used to align the ectopic premolar. Early treatment can, in many cases, prevent a molar-premolar transposition.

Early treatment of an ectopic premolar to prevent molar-premolar transposition.  

Science.gov (United States)

Orthodontic treatment is planned on an individual, case-by-case basis after thoroughly considering the patient's overall facial and dental characteristics, the expected duration of treatment, costs, patient preferences, and the orthodontist's experience. This article reports the treatment of a patient with a maxillary premolar-molar transposition in the permanent dentition that was successfully managed with orthodontic treatment. A girl, aged 10 years 2 months, came for treatment with an ectopic maxillary left premolar. Radiographic analysis indicated a developing complete transposition of the maxillary left premolar. The patient was treated with extraction of the deciduous molar and surgical exposure and ligation of the premolar. Eruption was properly guided, and the correct order of the 2 teeth was restored in the arch. This challenging treatment approach is described in detail, including the mechanics used to align the ectopic premolar. Early treatment can, in many cases, prevent a molar-premolar transposition.

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

Science.gov (United States)

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

CUBITAL TUNNEL SYNDROME: REVIEW OF 14 ANTERIOR SUBCUTANEOUS TRANSPOSITIONS OF THE VASCULARIZED ULNAR NERVE  

Directory of Open Access Journals (Sweden)

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

Stent dilation of superior vena cava and innominate vein obstructions permits transvenous pacing lead implantation.  

UK PubMed Central (United Kingdom)

The purpose of this study was to assess the feasibility of stent dilation of venous obstructions/occlusions to permit transvenous pacing lead implantation. Innominate vein or superior vena cava (SVG) obstruction may preclude the implantation of transvenous pacing leads. Patients with d-transposition of the great arteries, after a Mustard or Senning procedure, and children with previously placed transvenous pacing leads are at higher risk for this vascular complication. From May 1993 to January 1996, eight pediatric patients who underwent transvenous pacing lead implantation or replacement were found to have significant innominate vein or SVC obstruction or occlusion. Utilizing intravascular stents, a combined interventional and electrophysiological approach was used to relieve the venous obstruction and to permit implantation of a new transvenous pacing lead. Two patients had complete SVC occlusion requiring puncture through the obstruction with a transseptal needle. Vessel recanalization was achieved with balloon dilation and stent implantation. The remaining six patients had severe venous obstruction with a mean minimum diameter of 3.1 +/- 3.3 mm. The mean pressure gradient across the obstructed veins was 8.6 +/- 7.3 mmHg. Following implantation of 15 Palmaz P308 stents in eight vessels, the mean diameter increased to 14.2 +/- 1.9 mm and the mean pressure gradient across the stented vessels decreased to 1.0 +/- 2.0 mmHg. A transvenous pacing lead was implanted successfully through the stent(s) immediately or 6-8 weeks later. Innominate vein and SVC obstruction can be safely and effectively relieved with intravascular stents and permit immediate or subsequent transvenous pacing lead implantation.

Pulmonary Vein Varix: A Case Report  

Energy Technology Data Exchange (ETDEWEB)

Pulmonary vein varix is a rare vascular abnormality defined as localized pulmonary vein dilatation and is rarely reported in the literature. We report a case of pulmonary vein varix in a 20-year-old man who underwent a screening study for military service. The lesion was shown on CT as a focal dilatation of the pulmonary vein located before draining into the right inferior pulmonary vein and with no connection to the pulmonary artery. This lesion should be included in the differential diagnosis of pulmonary nodules.

Identification and Quantification of the Major Fungitoxic Components of the Brazilian Basil (Ocimum basilicum L.) Essential Oil  

Directory of Open Access Journals (Sweden)

Full Text Available Hydrodistillation of Brazilian basil (Ocimum basilicum L.) yielded 0.4% of essential oil (EO), with activity against eight important postharvest deteriorating fungi. The crude EO completely inhibited the radial growth of the fungi at a concentration of 0.1%. Thirty-two components were identified in crude EO by Kováts retention index, mass spectrometry and standards. Preparative TLC-bioautography of the crude EO presented only one band with an antifungal activity greater than that of crude EO with the following chemical composition (%): 1,8-cineole (6.2), linalool (36.3), camphor (9.7), Alpha-terpineol (3.8), methyl chavicol (9.1) and eugenol (34.9). Based on these results, these compounds were considered to be the major fungitoxic components. This is the first study in the literature that presents data obtained simultaneously on the activity of crude basil EO against eight important post-harvest deteriorating fungi, its unequivocal chemical identification and quantification (area %).

Congestive index of portal vein  

International Nuclear Information System (INIS)

In patients with portal hypertension, the blood flow volume is maintained despite decreased blood flow velocity due to enlargement of the vascular cross sectional area. Thus, the 'congestion index' of the portal vein, which is the ratio between the cross sectional area (cm2) and the blood flow velocity (cm/sec) determined by a Doppler ultrasonography, may be a sensitive index by which to assess portal hypertension. We performed Doppler ultrasonography on 24 normal subjects, 14 patients with biopsy proved chronic active hepatitis and 55 patients with liver cirrhosis in order to assess the diagnostic value of the congestion index. The cross sectional area of the portal vein was significantly enlarged and the mean blood flow velocity was significantly reduced in patients with liver cirrhosis compared with controls. However, the blood flow volume was no difference. The congestion index of the portal vein was significantly increased in patients with liver cirrhosis (0.113+0.035) compared with patients with chronic active hepatitis(0.078+0.029) (p

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.  

UK PubMed Central (United Kingdom)

UNLABELLED: 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.

Quantitatively Increased Somatic Transposition of Transposable Elements in Drosophila Strains Compromised for RNAi.  

UK PubMed Central (United Kingdom)

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.

Radiological evaluation of congenital pulmonary vein obstruction  

Energy Technology Data Exchange (ETDEWEB)

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 obstruction.

PATIENTS AND METHODS: We reviewed data from 70 patients who were undergoing laparoscopic pyeloplasty at our institution from March 2000 to December 2004 for ureteropelvic junction (UPJ) obstruction. An anterior crossing vessel was identified intraoperatively in 31 (44%) patients. The decision to transpose was made by the surgeon's intraoperative perception of the obstructive nature of the mobilized vessel after UPJ dismemberment. Outcomes between the groups who were undergoing transposition of the vessel (n = 8) were retrospectively compared with the group not undergoing transposition (n = 23). Success was defined by symptom resolution and evidence of improved drainage on diuretic renographic or urographic imaging. RESULTS: All 31 patients had resolution of obstruction. Both groups were similar as regards preoperative and postoperative differential function and t(1/2) on diuretic renography. The laparoscopic approach, however, was significantly different between the two groups. The majority of patients (87.5%) in whom the vessel was transposed underwent transperitoneal laparoscopic pyeloplasty. In contrast, the majority of patients (74%) in whom the vessel was not transposed underwent retroperitoneoscopic pyeloplasty (P = 0.004). As such, only 1 of 18 (6%) patients who were treated retroperitoneally received a vessel transposition compared with 7 of 13 (54%) of patients in whom the surgery was transperitoneally. CONCLUSIONS: During laparoscopic pyeloplasty, routine transposition of an anterior crossing vessel may be unnecessary. The decision to transpose appears to be governed by the surgeon's subjective intraoperative assessment and the choice of laparoscopic approach to facilitate technical ease of reconstruction.

Shifts in leaf vein density through accelerated vein formation in C4 Flaveria (Asteraceae).  

UK PubMed Central (United Kingdom)

BACKGROUND AND AIMS: Leaf venation in many C(4) species is characterized by high vein density, essential in facilitating rapid intercellular diffusion of C(4) photosynthetic metabolites between different tissues (mesophyll, bundle sheath). Greater vein density has been hypothesized to be an early step in C(4) photosynthesis evolution. Development of C(4) vein patterning is thought to occur from either accelerated or prolonged procambium formation, relative to ground tissue development. METHODS: Cleared and sectioned tissues of phylogenetically basal C(3) Flaveria robusta and more derived C(4) Flaveria bidentis were compared for vein pattern in mature leaves and vein pattern formation in developing leaves. KEY RESULTS: In mature leaves, major vein density did not differ between C(3) and C(4) Flaveria species, whereas minor veins were denser in C(4) species than in C(3) species. The developmental study showed that both major and minor vein patterning in leaves of C(3) and C(4) species were initiated at comparable stages (based on leaf length). An additional vein order in the C(4) species was observed during initiation of the higher order minor veins compared with the C(3) species. In the two species, expansion of bundle sheath and mesophyll cells occurred after vein pattern was complete and xylem differentiation was continuous in minor veins. In addition, mesophyll cells ceased dividing sooner and enlarged less in C(4) species than in C(3) species. CONCLUSIONS: Leaf vein pattern characteristic to C(4) Flaveria was achieved primarily through accelerated and earlier offset of higher order vein formation, rather than other modifications in the timing of vein pattern formation, as compared with C(3) species. Earlier cessation of mesophyll cell division and reduced expansion also contributed to greater vein density in the C(4) species. The relatively late expansion of bundle sheath and mesophyll cells shows that vein patterning precedes ground tissue development in C(4) species.

“Minority Report”: an analysis of the transposition of Philip K. Dick´s short story to cinema  

Directory of Open Access Journals (Sweden)

Full Text Available This article aims to make a comparative analysis of Philip K. Dick´s short story “Minority Report” with the homonymous film transposition made by director Steven Spielberg. The goal of the analysis is to understand how film transpositions are influenced by the ideological and economical aspects of the movie industry, which includes the movie audience demands, the use of the movie star image, the ideology related to this image, and how all these elements are reflected in the movie Minority Report. Therefore, we will analyze how all these aspects of the movie industry affected the film transposition of Philip K. Dick´s short story.

Efficiency of n-octyl-acetate, 2-heptanone and citronellal in repelling bees from basil (Ocimum sellowii - Labiatae)  

Directory of Open Access Journals (Sweden)

Full Text Available The objective of this study was to test repellent substances for honey bees, Apis mellifera, for basil, Ocimum sellowii, and to study the most frequent insects in this crop as well as its behaviors. The frequency of honey bees did not decrease with the application of n.octyl.acetate, citronellal and 2.heptanone, used as repellents, in the concentrations 2.5, 5.0, 7.5 and 10.0% diluted in water. However, when the products (20%) were diluted in water (75%) and glycerine (5%) were effective in repelling those bees of the basil flowers for a period of 20 minutes. The flower lasted, on average, 30 h from the bud phase until the flower withered. The flowers number opened by inflorescence was, on average, 5.65 flowers, and the inflorescence presented, on average, 160 flowers-buds. The basil was visited mainly for the honey bee (98.0%), followed by Augochloropsis electra bee - Halictidae (2.0%) and visits sporadics of Diptera and Lepidoptera, collected only nectar. The honey bee frequency increased during the day to 14:00, decreasing soon after, accompanying the curve of the temperature sets registered in the experiment days.O objetivo do experimento foi estudar a polinização em manjericão (Ocimum sellowii), a fim de verificar sua atratividade para as abelhas Apis mellifera, os insetos mais freqüentes, bem como seus comportamentos e testar substâncias repelentes para as abelhas A. mellifera. A flor durou, em média, 30 horas, desde sua abertura até o murchamento. O número de flores abertas por inflorescência foi, em média, 5,65 flores, sendo que a inflorescência possuía, em média, 160 botões florais. O manjericão foi visitado quase que exclusivamente pela abelha A. mellifera africanizada (98,0%), seguida pela abelha Augochloropsis electra-Halictidae (2,0%) e visitas esporádicas de dípteros e lepidópteros, sendo que todos coletavam apenas néctar. A freqüência da abelha africanizada aumentou no decorrer do dia até às 14 horas, diminuindo em seguida, acompanhando a curva da temperatura ambiente registrada nos dias do experimento. As abelhas africanizadas demoraram de 1 a 3 segundos em cada flor. A freqüência das abelhas africanizadas não diminuiu com a aplicação dos produtos n.octyl.acetato, citronellal e 2.heptanona, usados como repelentes, nas concentrações 2,5, 5,0, 7,5 e 10,0%, diluídos apenas em água. Entretanto, quando os produtos (20%) foram diluídos em água (75%) e glicerina (5%), foram efetivos em repelir essas abelhas das flores de manjericão, por um período de 20 minutos.

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

Directory of Open Access Journals (Sweden)

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

Small hepatic veins Budd-Chiari syndrome.  

UK PubMed Central (United Kingdom)

Budd-Chiari syndrome is a rare disorder characterized by hepatic venous outflow obstruction at any level from the small hepatic veins to the atrio-caval junction, in the absence of heart failure or constrictive pericarditis. Various imaging modalities are available for investigating the gross hepatic vascular anatomy but there are rare forms of this disease where the obstruction is limited to the small intrahepatic veins, with normal appearance of the large hepatic veins at imaging. In this cases only a liver biopsy can demonstrate the presence of a small vessels outflow block. We report two cases of small hepatic veins Budd-Chiari syndrome.

The importance of Mount Athos and the Ohrid Archbishopric for the policy of Basil II in the Balkans  

Directory of Open Access Journals (Sweden)

Full Text Available The essay ascertains that the monastic center located on Mount Athos and the Ohrid Archbishopric played a very important role in the policies pursued by Basil II. It was during his rule that the first foreign monasteries, which later Greek sources refer to as monastic communities ??????? ??????? (Iveron and Amalfi), were established. The third monastery displaying this characteristic was the Serbian monastery Hilandar. Since Hilandar had been established after the Bulgarian and Russian monasteries, the question arose why sources dating from the late 12th century do not mention Zographou and St. Panteleimon’s monastery among the ??????? ??????? monasteries. The answeris to be found in the circumstances surrounding the establishment of Slavic monasteries on Mount Athos. The essay also assesses the importance of Mount Athos and the Ohrid Archbishopric for the process of deeper integration of Slavs into the Byzantine religious and political-ideological system.

The Effect of Nitrogen Fertilization and Different Plant Densities on Some Agronomic and Technologic Characteristic of Ocimum basilicum L. (Basil)  

Directory of Open Access Journals (Sweden)

Full Text Available The effect of nitrogen fertilizer and non nitrogen fertilizer grown conditions with various densities of plants (20x20, 40x20, 60x20 cm) on yield and quality traits of Ocimum basilicum L. (Basil) were investigated under ecological conditions of Aydin during consecutive three years. As a result of this research, it was determined that the highest amount of green herb yield (4197.5 kg ha-1), drug herb yield (1078.6 kg ha-1), drug leaves yield (671.1 kg ha-1), essential oil ratio (0.826 %) and essential oil yield (5.164 L ha-1) were determined in 20x20 cm plant density with nitrogen fertilizer conditions, from 2000 to 2002 years. However, the highest essential oil ratio was obtained under non-nitrogen fertilizer condition with 20x20 cm plant density.

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

Directory of Open Access Journals (Sweden)

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

Screening of antifungal properties of essential oils extracted from sweet basil, fennel, summer savory and thyme against postharvest phytopathogenic fungi  

UK PubMed Central (United Kingdom)

The antifungal activity of essential oils of sweet basil (Ocimum basilicum L.), fennel (Foeniculum vulgare Mill.), summer savory (Satureja hortensis L.) and thyme (Thymus vulgaris L.) against two well-known postharvest fungi, Penicillium digitatum and Rhizopus stolonifer, by poison food medium (0, 200, 400, 600, 800 and 1,000 µL/L) and vapor phase (0, 5, 10, 15, 20, 25 and 40 µL) methods were assayed. The results showed that in poison food medium thyme oil had greatest antifungal activity against P. digitatum and R. stolonifer at 1,000 and ?600 µL/L, respectively. In vapor phase, thyme oil at ?5 µL completely inhibited the mycelial growth of pathogens. Summer savory oil at ?600 µL/L had a significant inhibitory effect on mycelial growth of R. stolonifer. Fennel oil showed the lowest antifungal activity against the pathogens. All the essential oil treatments completely inhibited the growth of R. stolonifer in vapor phase method. Also R. stolonifer were more sensitive against the essential oils. Gas chromatography-mass spectrometry analysis showed that main compounds identified in sweet basil, fennel, summer savory and thyme oils were linalool (65.25%), trans-anethole (64.42%), carvacrol (54.14%) and ?-ocimene (12.62%), respectively. Therefore, thyme and summer savory oils have a promising potential to use antifungal agent against fruit and vegetable fungi. The results of this work show that thyme, summer savory and fennel oils have a high potential to be used as an antifungal agents for control of postharvest phytopatogenic fungi especially in vapor phase method. Therefore, essential oils as safe aromatic compounds that do have not negative effects on human health and environment may be used as a novel and practical tool for preservation of postharvest quality of horticultural crops and are suitable alternative for synthetic fungicides.

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)

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

Arteries and veins of the zebra fish  

Science.gov (United States)

Arteries and veins are blood vessels and are part of the circulatory system. Arteries take oxygenated blood away from the heart and veins bring blood back to the heart after it has circulated through the body. The circulatory system distributes oxygen to the body and also moves around nutrients.

[Therapeutic transfemoral testicular vein occlusion of varicocele  

UK PubMed Central (United Kingdom)

It is reported on the percutaneous transfemoral obliteration of the testicular vein with ethoxysclerol. This method was used in 75 patients for the treatment of the varicocele. 81.3% could successfully be treated by this means. The applicability of the method is restricted by anatomical particularities in the course of the testicular vein. Advantages and disadvantages of the method are discussed.

Popliteal vein compression under general anaesthesia.  

UK PubMed Central (United Kingdom)

OBJECTIVES: To determine the incidence of popliteal vein compression in supine patients, who are under general anaesthesia and using heel elevators. DESIGN: A prospective cohort study. METHODS: The popliteal veins of 50 patients, lying supine under general anaesthesia, were insonated using duplex ultrasonography to determine the incidence of popliteal vein compression when the knees were flexed and extended. RESULT: There was a statistically significant reduction in popliteal vein diameter in extension compared with the diameter in flexion (median diameter: flexed 7.6mm, extended 2.1mm, p<0.001, Wilcoxon test). In extension, 43% of veins occluded, and a further 21% was compressed by >or=50%. There was a significant relationship to body mass index (BMI) but not to height, gender or age; all patients with BMI >or=30 displayed narrowing at least one vein by >or=50%. The relative risk of vein narrowing >or=50% or occlusion was 1.55 for BMI >or=25 versus <25, and 1.67 for BMI >or=30 versus <25. CONCLUSION: Knee hyperextension in supine patients during general anaesthesia leads to popliteal vein compression or occlusion. The likelihood of compression increases with higher BMIs.

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

Hydroxyapatite augmentation of the anterior portion of the maxilla with a modified transpositional flap technique.  

UK PubMed Central (United Kingdom)

Tunneling as a technique for augmentation of an atrophic maxilla has been described in the literature. The use of this technique has presented several prosthodontic problems, such as diffusion of material into adjacent tissues, incorrect positioning of the material on the ridge, and inadequate ridge height. Use of the transpositional flap technique described by Lew and modified by Williams has been used to overcome these problems. Twenty-five patients were treated with this method during a 30-month period. The patients had worn a maxillary complete denture for at least 5 years and had opposing natural mandibular anterior teeth with unsupported posterior occlusion. Use of the transpositional flap technique was shown to overcome the common prosthodontic problems seen with the tunneling procedure for anterior maxilla augmentation with hydroxyapatite.

UK PubMed Central (United Kingdom)

Internal jugular phlebectasia (IJP) is a rare disease in which there is a fusiform dilatation of internal jugular vein, usually presenting as a neck mass in children. Accurate diagnosis from careful history, physical examination, and radiological study can be made. We report a 12-year-old boy with history of swelling appearing on the right side of the neck only on straining, coughing, or during a Valsalva maneuver. Diagnosis of right IJP was made. Exploration and wrapping the dilated segment in an 8-mm-diameter polytetrafluoroethylene tube graft was done. Because of its rarity, this entity is frequently ignored or misdiagnosed. This case report intends to stress the importance of keeping IJP as differential diagnosis while dealing with such a swelling to avoid invasive investigations and inappropriate treatment.

Vein of galen malformations: Review  

Directory of Open Access Journals (Sweden)

Full Text Available Vein of Galen malformations are unique congenital malformations of the cerebral vasculature that result in persistence and 'aneurysmal' dilatation of the venous structures. The varied clinical presentations and their distinctive and complex angioarchitecture make it important for the caring physician to understand their embryological and pathophysiological aspects. Management of these lesions - both in the neonatal period and at the time of definitive intervention, is challenging. Considering the rarity of these lesions, there are very few studies that have been able to compare the results of different techniques in the management. Continuing developments in the diagnostic as well as interventional aspects during the last two decades have radically changed the management of these lesions. Antenatal diagnosis and referral to a center with facilities for advanced neonatal cardiac care as well as for interventional neuroradiological therapy can go a long way in improving the prognosis in these children.

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.

Double root switch: a complete anatomical correction for transposition of the great arteries.  

UK PubMed Central (United Kingdom)

We report the cases of two neonates with transposition of the great arteries, whose surgical correction consisted of translocation of the aortic root with the aortic valve and coronary arteries to the left ventricle and translocation of the pulmonary root with the pulmonary valve to the right ventricle. We believe that the aortic translocation may reduce the likelihood of dilatation of the neoaorta, aortic regurgitation, and changes in the endothelium of coronary arteries which have occasionally been seen following arterial switch operations.

UK PubMed Central (United Kingdom)

The hypothesis that female sex hormones in the first trimester of pregnancy are causally related to transposition of the great vessels (TGV) was tested by a retrospective study of 135 cases of TGV ascertained through the British Columbia Health Surveillance Registry. During 1962-1972 there was no increase in the annual incidence rates of TGV. Analysis of questionnaires completed on 58 cases revealed no definite association between inadvertent use of oral contraceptives or other sex hormones during early pregnancy and TGV.

Science.gov (United States)

A case of female false hermaphroditism is reported in a 30-year-old woman with urogenital sinus. This woman has undergone vaginoplasty and urethral transposition. The latter is not usually made in women with urogenital sinus. This leads to the position of the external urethral ostium in the depth of the newly formed vagina and, finally, to ectopia of the external urethral ostium or hypospadia. The result is that such woman suffers all life from urethritis, cystitis and vulvovaginitis. PMID:15114760

With congenitally corrected transposition of the great arteries, the right ventricle (RV) supports the systemic circulation. These patients have an increased risk of developing heart failure. Implantation of a ventricular assist device may be the only therapeutic option for patients who are not transplantation candidates. The technical aspects of implanting a mechanical device into the RV have not been well described, however. We describe our experience with one such case and describe our operative strategy in obtaining optimal placement of the inflow cannula.

UK PubMed Central (United Kingdom)

Vein wall fibrinolytic activity has been shown to be greater in the arms than the legs and it has been suggested that this difference is related to the greater hydrostatic venous pressure in the leg. Vein wall fibrinolytic activity and foot vein pressure has been measured in 40 legs from 30 patients, 25 with uncomplicated varicose veins and 15 with lipodermatosclerosis. No statistically significant correlation could be demonstrated between vein wall fibrinolytic activity and measured foot vein pressure.

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

Directory of Open Access Journals (Sweden)

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

Changes in yogurt fermentation characteristics, and antioxidant potential and in vitro inhibition of angiotensin-1 converting enzyme upon the inclusion of peppermint, dill and basil  

UK PubMed Central (United Kingdom)

The present study investigated the effects of peppermint (Mentha piperita), dill (Anethum graveolens) and basil (Ocimum basilicum) on yogurt formation, proteolysis and inhibition of angiotensin-1 converting enzyme (ACE). Herbal-yogurts had faster rates of pH reduction than plain-yogurt. All herbal-yogurts had higher (p < 0.05) antioxidant activities than plain-yogurt, both at the end of fermentation and throughout the storage period. The o-phthalaldehyde (OPA) peptides in herbal-yogurts increased by 28–36% after 7 days of storage. All herbal-yogurts showed higher anti-ACE activity than plain-yogurt at corresponding storage periods. M. piperita yogurt had highest inhibitory effect on ACE activity throughout the storage period. Peppermint, dill and basil may be used to modify microbial fermentation of milk with the intention of producing dairy products with higher antioxidant and enhanced anti-ACE activities.

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

Directory of Open Access Journals (Sweden)

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

Full Tendon Transposition Augmented with Posterior Intermuscular Suture and Recession - Resection Surgery  

Science.gov (United States)

Purpose To report an effect of the full tendon transposition augmented with posterior intermuscular suture and recession-resection surgery, for the patient with monocular elevation deficiency (MED) and large exotropia. Methods Interventional case report. Full tendon transposition augmented with posterior intermuscular suture and recession-resection surgery was performed for a 26-year-old male patient had monocular elevation deficiency (MED) and large exotropia. Results Preoperative angle of deviation was 56 prism diopters (PD) hypotropia and 45 PD right exotropia, compared with 18 PD left hypertropia and 10 PD right esotropia postoperatively. Essotropia persisted after 2.5 years, however, and so the right medial rectus was recessed after removal of the previous posterior intermuscular suture. At a three-year follow-up after the second surgery, alignment was straight in the primary position at near and far distances. Conclusions Full tendon transposition augmented with posterior intermuscular suture and recession-resection surgery was effective for a patient with MED associated with significant horizontal deviation, and a second operation was easily performed when overcorrection occurred.

Inferior alveolar nerve transposition with involvement of the mental foramen for implant placement.  

Science.gov (United States)

Inferior Alveolar Nerve (IAN) transposition is an option for prosthetic rehabilitation in cases of moderate or even severe bone reabsorption for patients that do not tolerate removable dentures. The aim of the present report is to describe an inferior alveolar nerve transposition with involvement of the mental foramen for implant placement. The surgical procedure was performed under local anesthesia, by the inferior alveolar, lingual and buccal nerve blocking technique. Centripetal osteotomy was performed, and bone tissue was removed, leaving the nerve tissue free in the foramen area. After that, transsection of the incisor nerve was performed, and lateral osteotomy was started from the buccal direction, toward the trajectory of the IAN. The procedure was concluded, by making use of a delicate resin spatula to manipulate the vascular-nervous bundle. The drilling sequence for placing the dental implants was performed, and autogenous bone was harvested using a bone collector attached to the surgical suction appliance. After the implants were placed, the bone tissue previously collected during the osteotomies and drilling processes was placed in order to protect the IAN from contact with the implants. The surgical protocol for inferior alveolar nerve transposition, followed by implant placement presented excellent results, with complete recovery of the sensitivity, seven months after the surgical procedure.

Mental nerve function after inferior alveolar nerve transposition for placement of dental implants.  

UK PubMed Central (United Kingdom)

BACKGROUND: One option for successful placement of dental implants in an atrophic posterior mandible without injury to the inferior alveolar nerve (IAN) is to transpose or lateralize the nerve. This procedure carries the risk of numbness along the distribution of the nerve, the complication that the procedure is undertaken to avoid in the first place. The purpose of the present study was to assess mental nerve function after transposition of the IAN. METHOD: We determined the outcomes of 20 IAN transposition procedures in 12 consecutive patients at the Queen Elizabeth II Health Sciences Centre in Halifax, Nova Scotia. The study included objective testing of sensory nerve function as well as subjective assessment by the participants. RESULTS: All subjects reported initial transient sensory disturbance. Objective testing after a minimum of 6 months revealed that, for each patient, affected sites had the same level of sensation as unoperated areas. Eighty percent of the patients said that the lower lip and chin felt normal. The others said that these structures did not feel exactly normal but that the difference was of no consequence. CLINICAL SIGNIFICANCE: It is concluded that IAN transposition can be safely and predictably performed with low risk to the mental nerve sensibility.

Results of treatment of chronic osteomyelitis by "gutter procedure and muscle flap transposition operation"  

Science.gov (United States)

INTRODUCTION: The aim of this study was to evaluate the outcomes of creation of a gutter and muscle flap transposition method for the treatment of long-bone chronic osteomyelitis. PATIENTS AND METHODS: A total of thirty chronic osteomyelitis patients (thirty-one extremities), who had undergone the gutter creation and muscle flap transposition procedure between 2005 and 2009, were included in the study (19 male, 11 female; mean age 24.4 years; age range 2-75 years). Osteomyelitis of the long bones involved the femur in 13 patients, the tibia in 13, the humerus in 2, the fibula in 2 and the ulna in 1 patients, respectively. All the patients received post-operative antibiotic therapy of at least 6 weeks. The mean follow-up period was 28.7 months (6-53 months). At the end of this follow-up period, the patients were evaluated using clinical, laboratory and screening methods. RESULTS: Complete pain relief, disappearance of toxic symptoms, improvement in radiological findings, fistula closure and return of the blood parameters to normal ranges were accepted as successful treatment when all the afore-mentioned had been fulfilled. According to these criteria, 29 of the 30 patients had been cured. DISCUSSION: The gutter creation and muscle flap transposition method in the treatment of long-bone chronic osteomyelitis may be a successful mode of therapy when performed correctly and supported by long-term antibiotherapy.

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

DEFF Research Database (Denmark)

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

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

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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

Pathogenesis and etiology of recurrent varicose veins.  

UK PubMed Central (United Kingdom)

BACKGROUND: Recurrent varicose veins (RVV) occur in 13% to 65% of patients following treatment, and remain a debilitating and costly problem. RVV were initially thought largely to be due to inadequate intervention, however, more recently neovascularization and other factors have been implicated. This review aims to provide an overview of the current understanding of the etiology and pathogenesis of RVV. METHODS: A systematic search of the PubMed database was performed using the search terms including "recurrent," "varicose veins," and "neovascularization." RESULTS: Three types of RVV have been reported, namely residual veins, true RVV, and new varicose veins, although the definitions varied between studies. RVV are attributable to causes including inadequate treatment, disease progression, and neovascularization. Using duplex ultrasonography, neovascularization has been observed in 25% to 94% of RVV. These new vessels appear in various size, number, and tortuosity, and they reconnect previously treated diseased veins to the lower limb venous circulation. Histologically, these vessels appear primitive with incomplete vein wall formation, decreased elastic component, and lack of valves and accompanying nerves. Although the rate of RVV following open surgery and endovenous treatment appears similar, neovascularization seems less common following endothermal ablation. Other causes of RVV following endovenous treatment include recanalization and opening of collaterals. CONCLUSIONS: Recurrence remains poorly understood following treatment of varicose veins. Neovascularization is an established and common cause of RVV, although other factors may contribute.

[Development of large vein surgery in Europe  

UK PubMed Central (United Kingdom)

Surgery of the great veins inevitably began with the surgical treatment of injuries, often involving the femoral vein. Because of the famous case presented by Roux in 1813, the prevailing opinion until almost the end of the nineteenth century was that ligation of the vein made death inevitable, but that the only way to control severe hemorrhaging from a vein was to ligate the femoral artery. Zaufal's principle (1880) consisted in the ligation and resection of great veins of the body and limbs in order to prevent sepsis in suppurative processes. This surgical method was still being used in the first half of the twentieth century in patients with perforated appendicitis or puerperal fever. In the limb, the congestion induced in the vein had a positive effect on the healing process. The surgical treatment of leg and pelvic deep vein thrombosis was initially (1931) aimed at achieving decompression in compartment syndromes. The first thrombectomy was performed in 1937, but several operations with a successful outcome were reported at the 61st annual meeting of the German Society of Surgery in the following year.

Portal vein gas in emergency surgery.  

UK PubMed Central (United Kingdom)

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

A reappraisal of saphenous vein grafting.  

UK PubMed Central (United Kingdom)

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 osteoplasty, 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.

Useful techniques for ultrasonography-guided free-hand puncture of a deep peripheral vein and catheter placement to obtain CT angiography.  

UK PubMed Central (United Kingdom)

PURPOSE: To show useful techniques for ultrasonography-guided free-hand puncture of a deep peripheral vein and catheter placement (UGFHCP). MATERIALS AND METHODS: The techniques were: favorable position of the patient's arm for puncturing the deep basilic vein, stable suspension of the transducer, and catheter lowering for advancement after successful venous puncture. During the study period, UGFHCP was performed for 75 of 263 patients who underwent coronary CTA. The patients were divided into two groups; those in the period before the development of the catheter lowering technique (n = 22, group A) and those after it (n = 53, group B). A catheter-based success rate was compared between groups A and B using Fisher's exact test. RESULTS: Neither cancellation of coronary CTA examination due to venous access trouble, nor subcutaneous leakage of contrast medium was seen in any of the 263 patients. There were 20 catheter-based successes and 18 catheter-based failures in group A, and 49 catheter-based successes and 9 catheter-based failures in group B. The catheter-based success rate was higher in group B, with a statistically significant difference (p = 0.001). CONCLUSION: UGFHCP achieved no cancellation of coronary CTA examination due to venous access trouble. The catheter lowering technique reduced the incidence of vessel perforation during catheter advancement, and increased the catheter-based success rate in UGFHCP.

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.

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)

[en] 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 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

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

UK PubMed Central (United Kingdom)

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

Radionuclide angiographic evaluation of right and left ventricular function during exercise after repair of transposition of the great arteries. Comparison with normal subjects and patients with congenitally corrected transposition  

International Nuclear Information System (INIS)

[en] We assessed the incidence, clinical significance and etiology of ventricular dysfunction after intraatrial repair of d-transposition of the great arteries in 11 patients, mean age 9 +/- 3 years, who had had Mustard operations. We compared the results to 15 patients who were considered to have normal ventricular function, two patients who had Rastelli operations and five patients with congenitally corrected transposition. Gated equilibrium radionuclide angiography with supine exercise stress testing was used to assess these children. We found no significant difference between our patient groups in exercise capacity, heart rate, or blood pressure response to exercise. However, we found a high incidence of right ventricular dysfunction in the patient groups, manifested by an abnormal right ventricular ejection fraction response to dysfunction in the patient groups, manifested by an abnormal right ventricular ejection fraction response to exercise in six of 11 patients with a Mustard repair, both patients with a Rastelli repair and all five with congenitally corrected transposition. In addition, the left ventricular response to exercise was abnormal in 10 of 11 patients who had undergone a Mustard repair, both patients with a Rastelli repair, and two of five patients with congenitally corrected transposition. We conclude that biventricular dysfunction is frequently present after intraatrial repair of d-transposition of the great arteries. Despite this dysfunction, no significant decrease in exercise tolerance is found in childhood

[Cavernous transformation of portal vein].  

UK PubMed Central (United Kingdom)

INTRODUCTION: In Cavernous transformation of portal vein (CTPV), therapeutic options are limited; however the restoration of circulation by mesenteric-portal bypass (MPB) is an option in selected cases. CASE REPORT 1: 13-year-old female with polymalformative syndrome. Admission at 4 months of age to Intensive Care Unit due to severe pneumonia with hemodynamic instability. Follow up due to thrombocytopenia and splenomegalia she was diagnosed CTPV at7-years old. At 13y-old she was submitted to MPB. CASE REPORT 2: 9-years-old male; severe neonatal Rh isoimmunization treated with exsanguinations. Followed-up since 6-months ofage due to thrombocytopenia and splenomegalia, and at 3 years of age he was diagnosed CTPV. Due to disease progression he was proposed as candidate to MBP which was contraindicated due to vascular thrombosis of the Rex recess. COMMENTS: MBP presents as one of the few therapeutic options to CTPV in children; due to its specificity and rigid requirements it is vital the close follow up and early diagnosis.

Translation and validation of the Dutch VEINES-QOL/Sym in varicose vein patients.  

UK PubMed Central (United Kingdom)

OBJECTIVES: To translate from English to Dutch and evaluate the psychometric properties of the VEnous INsufficiency Epidemiological and Economic Studies (VEINES) questionnaire, divided in symptom (VEINES-Sym) and quality of life (VEINES-QOL) subscales. METHODS: Standard forward-backward translation method was used to translate the 26 items of the VEINES-QOL/Sym. Eligible patients had to complete a standardized questionnaire. Demographic, venous disease characteristics, clinical venous signs, CEAP (clinical, aetiological, anatomical and pathological elements) classification and ultrasound findings were also noted. If item's scores were in an extreme category in more than 70% of patients a floor or ceiling effect was present. Feasibility of the individual items was considered poor if 5% or more of the responses were missing. The validity was tested by comparing the VEINES-QOL/Sym scores to the Short Form 36 (SF-36) scores and across the different 'CEAP' categories. Confirmatory factor analysis was used to assess the underlying structure of the VEINES-QOL/Sym. RESULTS: Sixty-six patients were included (response rate of 72%). None of the 26 items missed <10% of responses, but two showed ceiling effect. Both the VEINES-QOL and VEINES-Sym showed an excellent internal consistency (Cronbach's alpha of 0.88 and 0.81, respectively). The VEINES-QOL demonstrated a good construct validity for the physical component of the SF-36, but not for the mental component (rho = 0.62 and 0.22, respectively), as expected. The VEINES-Sym correlated poorly to both SF-36's components. According to the confirmatory principle axis factoring, only three out of 25 items did not load sufficiently on the factor. CONCLUSIONS: The Dutch VEINES-QOL/Sym can be used for health-related quality of life research in varicose veins patients and the evaluation of therapies.

Complications of umbilical vein catherisation. Case Report  

International Nuclear Information System (INIS)

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

Ovarian vein thrombosis in Behcet disease.  

UK PubMed Central (United Kingdom)

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

The plasma fibrinogen concentration, plasma fibrinolytic activity and the vein wall fibrinolytic activity of hand, groin, knee, ankle and perforating veins have been studied in 10 patients with skin changes in the lower leg secondary to venous disease (lipodermatosclerosis), in 10 patients with uncomplicated varicose veins and in 17 normal volunteers undergoing surgery. There was significantly more vein wall fibrinolytic activity in normal volunteers than in the patients with lipodermatosclerosis, not only in the ankle (P less than 0.001) but also in the hand (P less than 0.05). It is suggested that the reduced tissue fibrinolytic activity is a causative factor in the skin changes and ulceration of the post-phlebitic leg, and that since the reduced activity is not confined to the leg, it may be a primary systemic defect rather than a state secondary to venous congestion.

[Pulmonary vein stenosis after radio frequency ablation].  

UK PubMed Central (United Kingdom)

Physicians should be alert to the occurrence of respiratory symptoms after radio frequency ablation for the treatment of atrial fibrillation. Pulmonary veins stenosis could appear with an incidence of between 1 and 3% during the two years following the procedure. We present the case of a 41 year-old-male patient admitted with a three weeks old hemoptysis and thoracodinia and a prior history of a radiofrequency ablation procedure performed six months earlier. The angiotomography was not compatible with the diagnosis of pulmonary embolism and the angio-MRI detected hypoperfusion of the left upper pulmonary lobe. Consequently pulmonary veins angiotomography was requested, showing upper pulmonary lobe vein stenosis. An hemodynamic study with vein expansion and stent placement was successfully performed.

[Hemoptysis because of pulmonary vein stenosis and occlusion after pulmonary vein isolation for atrial fibrillation].  

UK PubMed Central (United Kingdom)

HISTORY AND ADMISSION FINDINGS: A 49-year-old woman was admitted because of hemoptysis for four months. Several bronchoscopies and thoracic computed tomographies at other hospitals had not revealed the cause of the sustained hemoptysis. Eight months before admission she had undergone pulmonary vein ablation (PVA) for paroxysmal atrial fibrillation. After the PVA she had initially received oral anticoagulation, but this had been stopped because of the hemoptysis. Physical examination at admission to our hospital was unremarkable except for moderate obesity and arterial hypertension INVESTIGATIONS: Ventilation/perfusion scintigraphy demonstrated combined ventilation and perfusion deficits in the left lower lobe. Transesophageal echocardiography strongly suggested stenoses of the left pulmonary veins. 3-D reconstruction of previously recorded computed tomographic images showed absence of the left inferior pulmonary vein (LIPV) and marked stenosis of the left superior pulmonary vein (LSPV). DIAGNOSIS: It was confirmed that the hemoptysis was caused by stenosis of the left pulmonary veins, resulting from the previous PVA. TREATMENT AND COURSE: Percutaneous transseptal balloon dilatation of the upper and lower pulmonary veins was successfully performed. The patient was put on oral anticoagulation and discharged home free of symptoms. CONCLUSION: Pulmonary vein stenosis must be considered as the most likely cause of hemoptysis and respiratory symptoms after pulmonary vein ablation for atrial fibrillation. Because of ever more frequent interventions to treat atrial fibrillation and other atrial arrhythmias, great clinical vigilance and an interdisciplinary approach is mandatory to assure optimal assessment of patients with acquired pulmonary vein stenosis.

Congenital narrowing of a pulmonary vein: slit-like pulmonary vein ostium.  

UK PubMed Central (United Kingdom)

We report the case of a 60-year-old female with a history of refractory paroxysmal atrial fibrillation. Preablation contrast enhanced pulmonary vein computed tomography (CT) scan demonstrated a slit-like narrowing of the left inferior pulmonary vein ostium. The narrowing measured approximately 3 mm, with poststenotic dilation. The patient had no prior history of ablation. The patient subsequently underwent segmental antral isolation of all four pulmonary veins and cavo-tricuspid isthmus ablation with bidirectional block. The diagnosis of preexisting congenital pulmonary vein stenosis had an impact on the type of ablation procedure performed (antral rather than ostial) and will affect the interpretation of postablation CT scans.

Primary leiomyosarcoma of the innominate vein.  

Science.gov (United States)

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

Right popliteal vein aneurysm: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Venous aneurysms are rare. Popliteal venous aneurysm can lead to severe complications such as deep vein thrombosis, pulmonary emboli and death if they remain undiagnosed or untreated. The authors report a case of popliteal vein aneurysm in the right popliteal fossa of a 60-year-old male cadaver. Most venous aneurysms have a congenital origin. An early diagnosis of popliteal venous aneurysm with ultrasound examination is essential prior to the occurrence of any thromboembolic or other major complications.

[Portal vein embolization prior to liver surgery].  

UK PubMed Central (United Kingdom)

Portal vein embolization is performed with the intention to occlude the portal veins to liver segments with malignancies and direct the portal flow to the healthy part (usually the left lobe) of the liver. Thus, hyperperfusion through the non-embolized part of the liver will create hyperplasia and hyperfunction, which allow extensive liverresection at a later stage in patients where it otherwise would have been contradictory to operate because of too small volume of the residual liver.

CT in thrombosed dilated posterior epidural vein  

International Nuclear Information System (INIS)

The authors report a case of thrombosis of the distal end of an enlarged right posterior epidural vein. The patient had a markedly narrow lumbar canal due to L5 spondylolisthesis. The dilated vein and the thrombosis were displayed by computed tomography but remained unrecognized until surgery. Pathogenesis of this condition is discussed. A review of the English, French and German literature revealed no prior radiological reports of a similar condition. (orig.).

The management of central retinal vein occlusion.  

UK PubMed Central (United Kingdom)

Central retinal vein occlusion is the result of outflow obstruction and is associated with a variety of medical conditions, mainly affecting the vascular system. Treatment of the coexistent medical conditions has no beneficial effect on visual outcome. Outflow obstruction has been treated by fibrinolytic agents and anticoagulants, hemodilution, and photocoagulation. None of these treatments were of value in improving or maintaining vision. Photocoagulation prevents neovascular complications in ischemic central retinal vein occlusion.

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.

Individual Pulmonary Vein Atresia in Adults: Report of Two Cases  

Energy Technology Data Exchange (ETDEWEB)

We present two cases of individual pulmonary vein atresia without vestige of an involved pulmonary vein. On CT, we noted the absence or interruption of normal pulmonary venous structures, and the presence of abnormal vascular structures that represented collaterals for the involved lung parenchyma. On angiography, the artertic pulmonary vein was found to drain into the other ipsilateral pulmonary veins through the collaterals.

Tn502 and Tn512 are res site hunters that provide evidence of resolvase-independent transposition to random sites.  

UK PubMed Central (United Kingdom)

In this study, we report on the transposition behavior of the mercury(II) resistance transposons Tn502 and Tn512, which are members of the Tn5053 family. These transposons exhibit targeted and oriented insertion in the par region of plasmid RP1, since par-encoded components, namely, the ParA resolvase and its cognate res region, are essential for such transposition. Tn502 and, under some circumstances, Tn512 can transpose when par is absent, providing evidence for an alternative, par-independent pathway of transposition. We show that the alternative pathway proceeds by a two-step replicative process involving random target selection and orientation of insertion, leading to the formation of cointegrates as the predominant product of the first stage of transposition. Cointegrates remain unresolved because the transposon-encoded (TniR) recombination system is relatively inefficient, as is the host-encoded (RecA) system. In the presence of the res-ParA recombination system, TniR-mediated (and RecA-mediated) cointegrate resolution is highly efficient, enabling resolution both of cointegrates involving functional transposons (Tn502 and Tn512) and of defective elements (In0 and In2). These findings implicate the target-encoded accessory functions in the second stage of transposition as well as in the first. We also show that the par-independent pathway enables the formation of deletions in the target molecule.
