Authors: Wagner Jan , Jiangzuo Qigao , Lenardić Jadranka Mauch , Liu Jinyi
Published: February 2019

Šandalja I palaeocave (“fossil” cave), situated in the southern part of the Istrian peninsula (Croatia), is a well-known locality due to the abundant fossil remains extracted from the bone breccia. It is broadly accepted that the fauna is Middle Villafranchian in age. Since the beginning, the taxonomic status of bear remains has caused controversy and, as a consequence, different authors listed between one to three bear species from this site. Detailed revision of dental material confirmed the presence of two bear species – Ursus thibetanus and U. deningeri. On the other hand, the previously reported presence of U. etruscus was refuted. Subsequently, based on the presence of these two bear taxa, the age of the whole faunal assemblage was re-evaluated and determined as Middle Pleistocene (Toringian).
Internal Return Migration in Rural of Vietnam: Reasons and Consequences
Authors: Thanh Ngo Trung , Lebailly Philippe , Dien Nguyen Thi
Published: February 2019

Many researchers have tried to explain the motivation behind out and return migration. However, few bodies of literature focus on selection of destinations of out migration, motives to return according to marriage status of migrants before the return and gender perspective of employments on the return. By surveying 68 returnees and applying participatory rural appraisal, this study shows that the personal and household characteristics of returnees before the migration create an effect on destination selections On the return, both single and married migrants are motivated by filial obligations to their parents. Single migrants’ motive associates to the potential failures that can be a burden on their livings after getting married. Married migrants’ motive to return results from living away from their children. This study also demonstrates that women play an important role in the development of agriculture. Additionaly, agriculture acts as a buffer to the negative impacts of return migration.

Published: February 2019

The purpose of the conducted study was to analyse new materials intended for contact with the human body in view of their physical, chemical and biological properties. The authors have put to test six commercially available materials, four out of which were composite polyamide 12-based materials, while two were polyurethanes. The examined materials were assessed in terms of the surface. Subsequently, their hardness and biocompatibility were tested. The authors devoted major attention to the tests of absorption and emissivity of water, the pH = 7.4 PBS buffer solution and pH = 4.3 artificial sweat in temperatures of 21°C and 37°C. The results of the tests have confirmed the non-toxicity of all the tested materials and allowed to provide their characteristics in terms of their surface, hardness, as well as absorption and emissivity of various body fluids. Both polyamide 12 and the tested polyurethanes are classified as thermoplastics that may be used in additive technology.

Published: February 2019

The development of this true scourge in the whole world demands a more accurate knowledge and documentation on the emergence, development, operation, motivation that underlies terrorist actions, as well as a knowledge of the funding of these terrorist groups. Considering the fact that this scourge has existed since antiquity and the Middle Ages, so it has a true “history”, developed gradually in the 1700s, it has experienced a real “explosion” since 1968, reaching the peak in 2001, it is necessary that those entitled to know in depth this “phenomenon” and if they can not eradicate it, at least to unite their efforts at an international level and limit it as much as possible. At global level, there are sufficient determinants, but also reasons for this phenomenon to have a continuous development, and we are taking in consideration the continuous development of the armaments industry and the misguided policies of some governments.

Published: February 2019

Quality of sleep developed to be a much disputed subject in everyday life performance of men. Our study focuses on comparing two samples one of non-sportive (formed by 42 students’ age 19 ± 1.22 years) and one of professional athletes (formed by 45 sportive age between 18 ± 2.01 years). The main method used for analyzing the quality of sleep between the two samples of the research was the Athlete Sleep Screening Questionnaire (ASSQ) that is a tool that analyses sleep behaviors, identify disorder in sleeping routine and determine the frequency of difficulties with sleep before and after events, competitions or intense training programs.

The results of the study showed a statistically significant differences between the two samples in the number of hours slept at night (the experiment sample having 8 to 9 hours of sleep compared with the control sample that have 6 to 7 hours); also we found differences between the time needed to fall asleep (less than 15 min at the experiment group compared with 31-60 min at the control group); less problems at sleeping in the experiment group compared with the control group and that the athletes from the experiment group are waking earlier and are a morning kind of persons compared with the control group that are more active at evening; also found differences at the caffeine doses consumed and usage of electronic devices before sleep time (the experiment have less cases compared with the control group). So the general conclusion of the study was that the level of satisfaction regarding the quality of sleep is higher at the experiment sample compared with the control sample.

Authors: Cerne Katarina , Hadzialjevic Benjamin , Skof Erik , Verdenik Ivan , Kobal Borut
Published: February 2019

Background

Osteopontin (sOPN) is a promising blood tumour marker for detecting epithelial ovarian cancer (EOC). However, other clinical uses of sOPN as a tumour marker in EOC are still lacking. Since sOPN concentrations in serum are not associated with those in ascites, we compared clinical value of sOPN concentrations in the two body fluids.

Patients and methods

The study included 31 women with advanced EOC and 34 women with benign gynaecological pathology. In the EOC group, serum for sOPN analysis was obtained preoperatively, after primary debulking surgery and after chemotherapy. In the control group, serum was obtained before and after surgery. Ascites and peritoneal fluid were obtained during surgery. sOPN concentrations were determined by flow cytometry bead-based assay.

Results

The sensitivity and specificity of sOPN in detecting EOC was 91.2% and 90.3% (cut-off = 47.4 ng/ml) in serum, and 96.8% and 100% (cut-off = 529.5 ng/ml) in ascites. Kaplan-Meier analysis showed a significant association between higher serum sOPN concentration and overall survival (p = 0.018) or progression free survival (p = 0.008). Higher ascites sOPN concentrations were associated with suboptimally debulked tumour and unresectable disease. Higher serum sOPN concentrations were associated with refractory disease or incomplete response to platinum-based chemotherapy.

Conclusions

The study showed that ascites sOPN level mirrors present disease and is superior to serum level for diagnostic purposes and surgical planning, although the end result of treatment is the response of the whole body in fighting the disease. The preoperative sOPN concentration in serum thus better reflects disease outcome.

Background
. Shared decision making (SDM) is becoming more and more important for the patient-physician interaction. There has not been a study in Romania evaluating patients’ point of view in the SDM process yet. Therefore, the present study aims to evaluate the psychometric parameters of the translated Romanian version of SDM-Q-9.

Material and methods
. A multicentric cross-sectional study was performed comprising eight recruitment centers. The sample consisted of in- and outpatients who referred to Hospital Units for treatment for atrial fibrillation or collagen diseases. Furthermore, patients who were members of Autoimmune Disease Patient Society were able to participate via an online survey. All participants completed the Romanian translated SDM-Q-9.

Results
. Altogether, 665 questionnaires were filled in within the hospital setting (n = 324; 48.7%) and online (n = 341; 51.3%). The Romanian version had good internal consistency (Cronbach α coefficient of 0.96.) Corrected item correlations were good ranging from 0.64 to 0.89 with low corrected item correlations for item 1 and item 7. PCA found a one-factorial solution (similar with previous reports) but the first item had the lowest loading.

Conclusion
. SDM-Q-9 is a useful tool for evaluation and improvement in health care that was validated in Romania and can be used in clinical setting in this country.

Published: February 2019

Quality of life studies in patients with knee osteoarthritis (OA) attest to the significant impact of the disease on day-to-day activities and social interactions. The aim of this study was to assess the efficacy of a physical exercise program on functional status and quality of life in patients with work-related knee osteoarthritis. The present study included 144 participants with knee osteoarthritis, 72% women, mean age (SD) 47.2 (11.1) years. The patients were randomly assigned in two lots based on the type of kinetic treatment: lot A-with knee OA and medication (72 patients) and lot B- with knee OA, medication and exercise program (72 patients). They followed for 12 days ambulatory exercise programs based on increasing knee flexion, muscular strength and endurance, improving balance, coordination, and respiratory exercises. The patients in the control group continued their daily living activities. The evaluation was made at the beginning of the study (T0), after 2 weeks (T1) and 8 weeks after the 12 days of exercise program (T2) and was based on the following parameters: knee mobility (knee flexion), muscular strength, pain assessment on a Visual Analogue Scale (VAS), functional status (Western Ontario &McMaster Universities Osteoarthritis Index - WOMAC) and quality of life evaluation using SF-36 Questionnaire (36-Item Short Form Survey). Out of 144 participants who completed the initial evaluation, 138 also completed the 2 weeks and the 8 weeks follow-up assessments: 70 patients from the control lot and 68 patients from the exercise lot. The benefits of the kinetic programs were shown by a significant improvement in knee mobility and muscular strength for knee extensors (quadriceps muscle) and knee flexor muscles. Testing the linear correlations between the SF-36 score and the VAS (r=0.71, p<0.05) and WOMAC (r=0.83, p<0.05) indicators demonstrates a highly positive relationship between the quality of life expression, the pain assessment score and the functional status score in patients with knee OA. The physical exercise program improves both functional status and quality of life in patients with work-related knee osteoarthritis by increasing the range of motion and muscular strength and by reducing pain.

These quasi-experiment research aims to identify any effect of music activities as media to reduce stress hassle on the subject which attend in the choir group. The musical repertoire which was used was the pop genre which technically did not have much complexities and the lyric straightforward to understand. Hassle stress is a stressor that involves minor everyday events such as traffic jam, activities of queuing, forgetfulness in putting the things, or turmoil. Manipulation or treatment treated to the subject as a member of the choir is totally N=10. The treatment was the singing rehearsal. The tools for collecting data were a questioner of self-report which contained questions and QRMA (Quantum Resonance Magnetic Analyzer) measurement which also focused on group discussion. The result shows that there is an effect of musical activities as media for reducing the stress hassle and promoting the previous research results. Some analysis shows that there should be an experiment with a different musical repertoire because a difference genre needs a different skill and there should be a necessity to measure a physical condition more accurately by QRMA to all participants.

Hyperpigmentation is caused by enhancement of melanin production that causes skin darkening. Purple sweet potato is one of the plants that is potentially developed as skin depigmentation agent because it contains anthocyanin. The most common types of anthocyanins in purple sweet potato are cyanidin and peonidin which are in vitro proven to be used as skin lightening. The objective of this study is to determine the potential of cyanidin and peonidin as skin depigmentation agent against target protein D-Dopachrome taumerase  through in silico molecular docking method. The research steps include the preparation of target protein using Chimera 1.10.1 program, optimization of cyanidine and peonidin 3D structures using Hyperchem 8 program, validation of molecular docking method, and docking of cyanidine and peonidine on target protein using Autodock 4.2 program. The bond energy between cyanidin and peonidin with the target protein D-Dopachrome taumerase are -7.75 kcal / mol and -8.38 kcal / mol. The cyanidin and peonidin bond values ??are smaller than the native ligand, suggesting that the bond between the test compound (cyanidin and peonidin) with the target protein are stronger and more stable than the native ligand, so that the affinity of the test compound was greater than the native ligand. This suggests that the cyanidin and peonidin compounds in purple sweet potato have potential as a depigmentation agent by inhibiting D-Dopachrome taumerase protein.

The aim of this research is to get activated carbon from sugarcane bagasse with high adsorption capacity to Naphthol Yellow S and to know factors influencing the adsorption capacity. Activated carbon is prepared by incomplete combustion of sugracane bagasse. The resulting carbon is activated with H2SO4 with concentration variation of 0.5; 1.0; 1.5 and 2.0 M and is continued by calcination at 400 °C. The measurement of the surface area of ??activated carbon by the methylene blue method indicates that the activation process successfully extends the surface area of carbon from 31.87 m2/g before activation to 66-72 m2/g after activation. Activated carbon with concentration of 2.0 M H2SO4 showed the highest surface area of ??71.85 m2/g, however, the best adsorption was shown by activated carbon with a concentration of 0.5 M H2SO4 with the adsorption capacity of 83.93%. The adsorption test showed that the best amount of adsorbent was 0.2 g with contact time for 30 minutes. Prolonged contact time can decrease the amount of Naphthol Yellow S adsorbed. The best adsorption test result was shown by sample with activator concentration of 0,5 M, mass of 0,2 g and contact time of 30 min with adsorption capacity 95,81% or amount of dye adsorbed equal to 143,72 mg/g. The adsorption study also showed that the entire Naphthol Yellow S adsorption process followed the Langmuir isothemal adsorption model. Qualitative testing of real batik waste indicates that activated carbon can reduce the dyes waste containing Naphthol Yellow Sexhibited by the color of batik waste which is more faded.
