Evaluation of quality of life of students
© 2016, International Journal for Quality Research. Quality of life is a theme that is becoming more and more prominent. Every man can express his opinion about the quality of their life, which allows a realistic assessment of the quality of life of a particular population on the basis of subjective feelings of its members. Therefore, in this study through surveys and questionnaires with more than 80 questions from 11 subject areas is attempted to form a picture of the quality of life of the student population of the University of Montenegro (UM). The survey covered 14 units and 60 university students and the results of this survey have provided answers to some key questions by which the guidelines for raising the quality of life of students were obtained
Comparative analysis of chemical profiles, antioxidant, antibacterial, and anticancer effects of essential oils of two Thymus species from Montenegro
The essential oils of Thymus vulgaris (TVEO) and Thymus serpyllum (TSEO) show different biological activities. The aim of the study was to evaluate the biological activities of TVEO and TSEO from Montenegro. The main components of TVEO were p-cymene (29.52%), thymol (22.8%) and linalool (4.73%) while the main components of TSEO were p-cymene (19.04%), geraniol (11,09%), linalool (9.16%), geranyl acetate (6.49%) and borneol (5.24%). Antioxidant activity determined via DPPH for TVEO was 4.49 and FRAP 1130.27, while for TSEO it was estimated that DPPH was 4.88 μL/mL and FRAP was 701.25 μmol FRAP/L. Both essential oils were active against all tested bacteria, with the highest level of sensitivity of E. coli with MIC of 1.5625 μL/mL. Essential oils showed strong cytotoxic effects on human cancer cell lines, with IC50 values ranging from 0.20 to 0.24 μL/mL for TVEO and from 0.32 to 0.49 μL/mL for TSEO. TVEO caused apoptosis in cervical adenocarcinoma HeLa cells through activation of caspase-3 and caspase-8, while TSEO caused apoptosis through caspase-3. EOs decreased levels of oxidative stress in normal MRC-5 cells. HeLa cells treated with TVEO had reduced MMP2 expression levels, while cells treated with TSEO had lowered MMP2 and MMP9 levels. The treatment of HeLa cells with TVEO increased the levels of miR-16 and miR-34a, indicating potential tumor-suppressive properties. Our findings suggest that Thymus essential oils may be considered as good candidates for further investigation as cancer-chemopreventive and cancer-therapeutic agents
Homogeneity of the Hb Lepore gene in FR Yugoslavia
Screening analysis of Yugoslav patients with suspected thalassemia syndromes in last 4 years revealed six patients who were Hb Lepore carriers. Three were compound heterozygotes for Hb Lepore and β-thalassemia, and they were affected with a thalassemia major syndrome. Family studies revealed 12 heterozygous relatives. All heterozygous carriers of Hb Lepore had a clinical phenotype of thalassemia trait. The detection of Hb Lepore was carried out by electrophoresis on cellulose acetate and confirmed by gap-polymerase chain reaction analysis of patients' DNA. Sequence analysis of all the Hb Lepore genes showed the same DNA sequence, indicating that the mutation was of the Hb Lepore-Boston-Washington type. Moreover, a single base substitution within the second intervening sequence [IVS-II-74 (G→T)] was detected in all analyzed hybrid genes. The molecular characteristics of this homogeneity represent additional data for the probable Balkan origin of this mutation
Altered organization of collagen fibers in the uninvolved human colon mucosa 10 cm and 20 cm away from the malignant tumor
Remodelling of collagen fibers has been described during every phase of cancer genesis and progression. Changes in morphology and organization of collagen fibers contribute to the formation of microenvironment that favors cancer progression and development of metastasis. However, there are only few data about remodelling of collagen fibers in healthy looking mucosa distant from the cancer. Using SHG imaging, electron microscopy and specialized softwares (CT-FIRE, CurveAlign and FiberFit), we objectively visualized and quantified changes in morphology and organization of collagen fibers and investigated possible causes of collagen remodelling (change in syntheses, degradation and collagen cross-linking) in the colon mucosa 10 cm and 20 cm away from the cancer in comparison with healthy mucosa. We showed that in the lamina propria this far from the colon cancer, there were changes in collagen architecture (width, straightness, alignment of collagen fibers and collagen molecules inside fibers), increased representation of myofibroblasts and increase expression of collagen-remodelling enzymes (LOX and MMP2). Thus, the changes in organization of collagen fibers, which were already described in the cancer microenvironment, also exist in the mucosa far from the cancer, but smaller in magnitude
Anthropogenic Pressures on Watercourses of the Danube River Basin in Montenegro
The surface area of Montenegro’s portion of the Black Sea drainage basin is 7075 km2, or 0.9% of the entire basin, and is made up of the rivers Tara, Piva, Lim, Ćehotina and Ibar, and Lake Plav. The major polluters of watercourses are wastewaters and solid waste from inhabited settlements. According to water categorization regulations, the rivers of the Danube Basin in Montenegro are, based on the status quo, classified into four quality classes. Thus, the mid- and lower courses of the larger rivers fall within quality classes II and III. The water quality of the Lim, downstream of Berane, worsens at its exit from Montenegro and falls into quality class III. The Ibar profile downstream of Bać is largely out of a prescribed class. The Ćehotina downstream of Pljevlja is in water quality class III, and occasionally out of a prescribed class. The Tara belongs to the Durmitor National Park, but its water quality is class I only at its most upstream profile; its profiles downstream of Kolašin are from class II to class III. These findings are confirmed by analyses of their aquatic macroinvertebrate communities, i.e. Oligochaeta, as bioindicators of water quality. The ichthyofauna of the Danube Basin rivers in Montenegro comprises 20 fish species. Hydromorphological alterations of watercourses, such as dam construction, have a significant effect on fish populations. Thus, the dam on the Piva river has a negative effect on the fish population, presenting a barrier to migration routes, as is the case with huchen or Danube salmon (Hucho hucho)
An international assessment of the adoption of enhanced recovery after surgery (ERAS®) principles across colorectal units in 2019–2020
AimThe Enhanced Recovery After Surgery (ERAS®) Society guidelines aim to standardize perioperative care in colorectal surgery via 25 principles. We aimed to assess the variation in uptake of these principles across an international network of colorectal units.MethodAn online survey was circulated amongst European Society of Coloproctology members in 2019–2020. For each ERAS principle, respondents were asked to score how frequently the principle was implemented in their hospital, from 1 (‘rarely’) to 4 (‘always’). Respondents were also asked to recall whether practice had changed since 2017. Subgroup analyses based on hospital characteristics were conducted.ResultsOf hospitals approached, 58% responded to the survey (195/335), with 296 individual responses (multiple responses were received from some hospitals). The majority were European (163/195, 83.6%). Overall, respondents indicated they ‘most often’ or ‘always’ adhered to most individual ERAS principles (18/25, 72%). Variability in the uptake of principles was reported, with universal uptake of some principles (e.g., prophylactic antibiotics; early mobilization) and inconsistency from ‘rarely’ to ‘always’ in others (e.g., no nasogastric intubation; no preoperative fasting and carbohydrate drinks). In alignment with 2018 ERAS guideline updates, adherence to principles for prehabilitation, managing anaemia and postoperative nutrition appears to have increased since 2017.ConclusionsUptake of ERAS principles varied across hospitals, and not all 25 principles were equally adhered to. Whilst some principles exhibited a high level of acceptance, others had a wide variability in uptake indicative of controversy or barriers to uptake. Further research into specific principles is required to improve ERAS implementation.AimThe Enhanced Recovery After Surgery (ERAS®) Society guidelines aim to standardize perioperative care in colorectal surgery via 25 principles.
