Abstract

This study aimed at investigating significant differences in the level of intercultural competence of students before attending an internship of international mobility by the intermediary of the Erasmus Plus program, depending on their field of study. The three areas of study that imply the students attending the research are: military, exact science and humanities. The research was processed by a questionnaire measuring the level of intercultural competence, the items being structured on the three dimensions of intercultural competence: knowledge, attitudes and abilities. The results indicate that significant differences exist only at the level of the attitude’s component, the highest average being registered for the field of exact sciences.

Abstract

This study aims to evaluate intercultural competence for military students before they go on an international mobility stage and after its completion, in order to see if intercultural competence is formed in real intercultural contexts. In the study, we addressed both theoretical and practical aspects of intercultural competence. As an instrument for data collection, an intercultural competency assessment questionnaire was used and, following its application, it was found that the high level of the “knowledge” component of intercultural competence determines a higher level of the other two elements - “attitudes” and “skills”.

Abstract

The present research aims to identify the training needs of military students and their perceptions about the importance and necessity of training the intercultural competence, before participating in an international mobility stage. Their mobility takes place within the international Erasmus Plus program. The questionnaire that was the basis of this research had two dimensions. Following the processing of the results, it was found that the students need to be well trained before interacting with a new culture.

Abstract

Among bioactive constituents occurring in mushrooms, phenolic compounds focus attention due to their antioxidant activity. Also, a special attention is given to mushrooms secreting extra cellular enzymes such as lignin peroxidases (LiP), manganese peroxidase (MnP) and laccase (Lac), enzymes which can be used in biodegradation processes. The aim of the present study was to investigate ten mushroom species for total phenolic compounds, lignocellulolytic enzymes and for their synthetic dyes decolourisation potential. For this purpose, 70% ethanol extracts of ten dried mushrooms were analysed using spectrophotometric methods. The results revealed that total phenolic compounds in the extracts were the highest in A. campestris, P. ostreatus var. Florida and T. versicolor. Laccase activity showed high values in extracts from P. ostreatus var. Florida, A. campestris, L. edodes, and G. applanatum. Lignin peroxidases (LiP) activity showed high values in extracts from A. campestris, F. velutipes, P. ostreatus var. Florida and T. versicolor, whereas manganese peroxidase (MnP) activity was highest in extracts from P. ostreatus var. Florida, A. campestris and G. applanatum. It was found that some of the fungal extracts showed high activities in decolorizing of synthetic dyes.

Abstract

Polyphenolic compounds were determined from a pharmaceutical (tincture) and a cosmetic preparation (rose water), both obtained from the Rosae damascenae flores. Separation of the phenolic compounds was done by a HPLC method, using a Zorbax XDB or equivalent column C18, 250 mm x 4,6 mm; 5 μm. A gradient elution was performed with phosphoric acid and acetonitrile eluted under gradient conditions. The flow rate was 1.5 mL/min and the injection volume was 20 μL. HPLC method for determination of caftaric acid presented in this paper, has been validated. The results were statistically analyzed with SPSS 10 software.

Abstract

A rapid high performance liquid chromatography method, using a monolithic column, was developed for quantitative determinations of benzodiazepines (diazepam, clonazepam, lorazepam, midazolam) in whole blood. A liquid-liquid extraction step with n-chlorobutane isolates the drugs from alkalinized blood. The separation was carried out in reversed phase conditions using a Chromolith Performance (RP-18 100x4.6 mm) column. For the mobile phase, a mixture of a phosphate buffer (pH= 2.5)/acetonitrile (65/35 v/v), in isocratic mode at 2 mL/min. An ultraviolet spectrophotometer was used as the detector at the wavelength of 220 nm. The total run time of the analytical method is less than 4-6 minutes. The calibration curves showed linearity and the correlation coefficient of each individual curve was greater than 0.995. The method was linear over a concentration range of 0.03-0.6 μg/mL for clonazepam, lorazepam and midazolam. For diazepam of linearity was over the range 0.04-5.0μg/mL. Quantification limits ranged from 0.03-0.04μg/mL and the accuracy were from 80% to 105% for the recovery test.

The results indicate that this analytical method is simple, specific, accuracy, sensitive, demonstrating from the validation data and a higher robustness. The proposed method is applied routinely in forensic toxicological analysis involving blood.

Abstract

Mucoceles are benign, expansive, cystic tumors, affecting especially the adult, with development in the paranasal sinuses. Clinical symptoms are not specific. These are rare conditions that originate within the sinusal mucosa, favoured by the obstruction of the sinus ostium. Due to the inflammation and the expansive character of the tumor, with the erosion of the bony walls, combined forms can develop, with the involvement of two or more sinuses, most frequently with fronto-ethmoidal localization.

The authors carry out a clinical retrospective study on 25 cases of mucoceles of the paranasal sinuses, diagnosed and treated in the ENT Clinic of the “Sfantul Spiridon” Emergency Clinical Hospital Iasi, during 2015-2019. The authors insist on aspects related to clinical and radiological diagnosis (CT scanner), as well as surgical treatment by external approach.

The postoperative evolution is generally simple, with full recovery, without complications or recurrences.

The diagnosis of the mucoceles of the paranasal sinuses consists in radiologic techniques by preoperative CT scan examination, intraoperative macroscopic aspect and histopathological result.

Surgical approach with complete excision of the tumor and creating a new sinusal drainage path prevents the occurrence of recurrences.
