Ecologically acceptable usage of derivatives of essential oil of sweet basil, Ocimum basilicum, as antifeedants against larvae of the gypsy moth, Lymantria dispar

Ethanol solutions of five fractions obtained from essential oil of sweet basil Ocimum basilicum L. (Lamiales: Lamiaceae) (F1-F5) were tested for their antifeedant properties against 2nd instar gypsy moth larvae, Lymantria dispar L. (Lepidoptera: Lymantriidae), in laboratory non-choice and feeding-choice experiments. Prior to bioassays, the chemical composition of each fraction was determined by gas chromatography analyses. Significant larval deterrence from feeding was achieved by application of tested solutions to fresh leaves of the host plant. The most effective were F1 (0.5%), F4 (0.05, 0.1, and 0.5%), and F5 (0.1 and 0.5%), which provided an antifeedant index > 80% after five days. A low rate of larval mortality was observed in no-choice bioassay. In situ screening of chlorophyll fluorescence as an indicator of plant stress level (assessed by the induced fluorometry) confirmed that the tested compounds did not cause alternations in the photosynthetic efficiency of treated leaves

Iako se u literaturi naglašavaju nedostaci merenja citiranosti kao pokazatelja kvaliteta, ona je i dalje jedno od merila vrendovanja učinka istraživača i institucija kojoj pripadaju. Većina autora traga za najuspešnijim tehnikama za povećanje citiranosti svojih radova. U radu je dat predlog za povećanje citiranosti korišćenjem specifičnih metoda, koje su autori podelili u tri oblasti: putem kvaliteta i strukture naučnog rada, izbora naučnog časopisa i promocije rezultata istraživanja

Capacity and Level of Service on the Zagreb Bypass

As the capital of the Republic of Croatia, Zagreb is certainly the biggest motorway interchange, as well as the origin and destination of a large number of trips. Apart from obvious advantages, road traffic with its sudden development has caused certain undesired consequences as well, out of which the focus is on the traffic network congestion, including reduction of safety level, mainly because of the greater number of traffic accidents most pronounced in the summer months. The morning and afternoon hours see the highest traffic peaks at junctions, first of all at Buzin where long queues of vehicles are formed. In order to solve the problem the capacity and level of service need to be analysed and the attention should be drawn to the possible requirement of implementing measures in order to increase the capacity and the level of service in the corridor of the Zagreb Bypass

Development of Road Traffic Assignment and Assessment Sub-Model Applied in the Traffic Study ...

The described sub-model is just one small segment of theTraffic Study of the City of Zagreb, in the development of whichnumerous foreign and national experts and institutions tookpart. After comprehensive collection and processing of inputdata, the traffic experts, using the software package "MVATRIPS" for the analysis and search for optimal solutions to theproblem of traffic system, provided the models of public urbantransit for the future.This paper describes the analysis and assessment of sub-models in road traffic assignment for the morning peak, afternoonpeak and average off-peak hours. The principles of assignmentprocedure have been described as well as the convergencetests. The following has been specified: the users categories,the public transit pre-load, and the passenger car unit(PC U). The key guideline in selecting the route is a generalisedformulation of costs presented in the paper. The procedures ofcalibration and the assessment of the finite model have alsobeen defined according to the screenline flows, link flows, andtravelling times. In the end, the summary is given of the basiccharacteristics of the finite travelling matrices

Surgical approach and results of treating two subcategories pT2 glottic carcinoma of the larynx

Background: T2 glottic carcinoma is a nonhomogenous localization of laryngeal carcinoma with two subcategories. The aim of the study was to retrospectively analyze the results of surgically treated pT2 glottic carcinomas and to determine the importance of subcategories of glottic carcinomas in diagnostics, surgical treatment, and patients’ survival. Methods: During the period 1990-2000, 71/701 (10%) patients were diagnosed. with pT2 glottic carcinoma. All patients were treated with different surgical techniques. Results: Total laryngectomy was performed in 14/71 patients. Involvement of anterior commisure in local spreading of the cancer was found in 24/71 patients; total laryngectomy was performed in 13/24 and reconstructive surgery in 11/24. Selective resection of neck was done in 49 patients and metastases were found in 2 of these patients. Out of fifty-seven patients who had reconstructive laryngeal surgery local disease recurrence appeared in 8 patients. These 8 patients were treated with total laryngectomy. Overall 5-year survival was 90.1% with a slight difference between subcategories (89.1% subcategory I; 93.7% subcategory II) which was not statistically significant (p>0.05). Disease free 5-year survival was 83.6% with a difference between subcategories (81.1% subcategory I; 93.3% subcategory II) which was not statistically significant (p>0.05). Conclusion: Spreading of glottic carcinoma toward supraglottic and subglottic structures complicates exact preoperative evaluation of tumor size regardless to preoperative diagnostic procedures. Just owing to that, larger surgical resections performed bring more radicalness with less percentage of local recurrence and better effects on overall survival and disease free survival rate

Endoscopic repair of cerebrospinal fluid rhinorrhea

Abstract Introduction: Nasal liquorrhea indicates a cerebrospinal fluid fistula, an open communication between the intracranial cerebrospinal fluid and the nasal cavity. It can be traumatic and spontaneous. Objective: The aim of this study was to assess the outcome of endoscopic repair of cerebrospinal fluid fistula using fluorescein. Methods: This retrospective study included 30 patients of both sexes, with a mean age of 48.7 years, treated in the period from 2007 to 2015. All patients underwent lumbar administration of 5% sodium fluorescein solution preoperatively. Fistula was closed using three-layer graft and fibrin glue. Results: Cerebrospinal fluid fistulas were commonly located in the ethmoid (37%) and sphenoid sinus (33%). Most patients presented with traumatic cerebrospinal fluid fistulas (2/3 of patients). The reported success rate for the first repair attempt was 97%. Complications occurred in three patients: one patient presented with acute hydrocephalus, one with reversible encephalopathy syndrome on the fifth postoperative day with bilateral loss of vision, and one patient was diagnosed with hydrocephalus two years after the repair of cerebrospinal fluid fistula. Conclusion: Endoscopic diagnosis and repair of cerebrospinal fluid fistulas using fluorescein intrathecally has high success rate and low complication rate

Frequency and intensity of symptoms in patients with chronic rhinosinusitis

Introduction/Objective. Chronic rhinosinusitis is one of the most frequent chronic disorders which significantly influences the patients‘ quality of life. The objectivе of this paper was to examine which are the most frequent and intensive symptoms in patients with chronic rhinosinusitis, and also to determine whether there is a correlation between a subjective assessment of the disease as a whole and individual symptoms. Methods. The study encircled 90 patients with clinical diagnosis of chronic rhinosinusitis that was endoscopically proven and computer tomography of the nose and paranasal sinuses. Every possible symptom was recorded in every patient (nasal congestion, nasal discharge, facial pain/pressure, reduction or loss of smell, headache, fatigue, cough, halitosis and ear pain/fullness), the intensity of every possible symptom as well as the disorder as a whole. The patients assessed the intensity of their symptoms on the visual analogue scale. Results. Nose congestion is the most frequent symptom. It occured in 82 patients (91.1%), followed by nasal discharge in 81 patients (90%) and there was no difference in frequency of these two symptoms. Nasal discharge has been recorded as the most intensive symptom (x– = 5.4) and it is significantly more intensive in comparison to nasal congestion which was the second on the intesity list (x– = 4.1, p = 0.002). All other symptoms were significantly less frequently and less intensive. The average intensity value of the disease as a whole is the same as the average intensity value of the nasal discharge (x– = 5.4) while the average intensity values of all other symptoms are statistically significantly lower than the average intensity value of the disease as a whole; in all comparisons p < 0.001. Conclusion. Nasal congestion and nasal discharge are the most common symptoms in the patients with chronic rhinosinusitis. Nasal discharge is the most intensive symptom in patients with chronic rhinosinusitis while its intensity determines the sensation of the intesity of the disorder as a whole
