Mind Term Effects of a Single Injecton versus three Injecton of Hyaluronic Acid in Patients with Rhizarthrosis

Background. To compare the effects of a single intra-articular injection of low molecular weight hyaluronic acid (LMWHA) versus 3 injections of the same LMWHA in patients affected by rhizarthrosis. Methods. 40 patients received ultrasound (US) guided injections of LMW HA: Group A (20 patients) injections with 1 ml HA; Group B (20 patients) once a week for 3 times injections of 1 ml HA. Both groups were examined at baseline, at 1, 3 and 6 months follow-up using VAS (Visual Analogue Scale), Kapandji Thumb Opposition Test, DASH Score (func-tional assessment questionnaire) and DASH Work. Results. Patients treated with a single HA injection had a statistically significant improvement (p<0.05) of the VAS at 1- and 3-months follow-up compared to baseline, and of Kapandji thumb opposition test only at 6 months compared to baseline. Patients received 3 HA injections shown a statistically significant improvement (p< 0.05) of the VAS, DASH score, DASH-work and Kapandji thumb opposition test at 1, 3- and 6-months follow-up compared to baseline. The intergroup analysis did not underline any significant differences between the two groups at all follow-up. Conclusions. The intra-articular HA injections allowed good effects in patients suffering from rhizarthrosis. To have a low term pain relief a single injection can be used. The 3 injections protocol is more indicated if we want to obtain also a functional improvement.
Alternative Proposals to Measure Consumer Ethnocentric Behavior: A Narrative Literature Review

CETSCALE (Consumer Ethnocentrism Tendencies Scale), the scale developed by Shimp and Sharma in 1987 to study consumer ethnocentric behavior, has received preferential use in the literature, with numerous replications carried out in countries on all continents. Although it was proposed as a 17-item scale along with a smaller version of only ten items, studies that use only a part of these have been become increasingly common. To some extent, this practice responds to the multidimensional behavior of CETSCALE, as can be widely confirmed. It is for this reason that a growing consensus is in favor of reviewing the scale as a tool to measure ethnocentrism, made evident by the appearance of new alternative scales. CEESCALE and CES are two of the most recent proposals, which were developed with a similar number of items but grouped into a number of clearly defined dimensions, providing more robust results.
Effect of length and insertion angle on stability of miniscrews used for retraction of anterior teeth-an in vitro study

Aim: To assess the effect of length and insertion angle on stability of mini screw in synthetic bone replica used for retraction of anterior teeth. Materials and Methods: A total of 120 titanium miniscrews (SK Surgicals) were equally divided into two groups based on their insertion in synthetic replica of bone (ORTHOBONES, 3B scientific, Germany) i.e. maxillary (Group I) or mandibular (Group II) bone. Both the groups were further divided into 8 subgroups based on length and angulation i.e. Ia60 (8mm, 60), Ia90 (8mm, 90), Ib60(11mm, 60), Ib90(11mm, 90), IIa60(6mm 60), IIa90(6mm 90), IIb60(8mm 60) and IIb90(8mm 90). Two customized angulation guiding jigs, at 60 and 90 angle were fabricated. Miniscrew was driven into the bone using the screwdriver. A Universal testing machine was used to conduct Shear Compressive Strength test on all the Miniscrews. Data was collected and ANOVA and Post Hoc Test were applied to get the results. Result: For maxillary bone analogue (Group I), 11 mm miniscrew inserted at 90 angulation had maximum values and 8 mm screws at 60had minimum values of SCS. The trend for SCS of miniscrews in Group I was Ib90>Ib60>Ia90>Ia60. In mandibular bone analogue, 8 mm miniscrews inserted at 90 angulation showed maximum stability and 6mm at 60showed minimum SCS. The trend for SCS in Group II was IIb90>IIa90>IIb60>IIa60. Intergroup comparison revealed that statistical difference for IIb60>Ia60, IIb90>Ia90, IIb90>Ia60 and IIb60>Ia90 which suggest that MS inserted in mandibular analogue had better SCS than in maxilla irrespective of angulation. Conclusion: Longer miniscrews inserted perpendicular to the bone gives maximum stability. It is also found that stability increases with increase in cortical bone thickness.
Impact of quercetin supplementation on testicular functions in summer heat-stressed rabbits

The current study was designed to determine the effects of dietary quercetin on epididymal sperm and testicular changes in male rabbits during summer heat stress (HS). Twelve adult male New Zealand white rabbits were submitted to summer heat conditions (temperature-humidity index 29.9±1.2). One group was fed a basal ration (BR; n = 6), whereas the other group was fed the same basal diet supplemented with quercetin (30 mg/kg d; Que-BR; n = 6) for 60 d, and both groups were sacrificed at the end of the experiment. Epididymis and testicles isolation was done for sperm, histopathology and apoptosis assessments. The results showed that quercetin improved epididymis weight, but did not affect other testicular dimensions except testicular length. A significant improvement was observed in epididymal sperm motility, concentration, kinematic parameters, viability, mitochondrial potential and acrosome integrity in Que-BR compared to the BR group. Lowered serum malondialdehyde level was observed in quercetin supplemented rabbits. Moreover, the quercetin supplementation maintained the interstitial stroma, seminiferous tubules architecture, germinal and Sertoli cells under HS, decreasing the apoptotic germ cell rate in seminiferous tubules. In conclusion, HS condition affects the sperm and testes configurations in rabbits and dietary quercetin minimises oxidative stress, which in turn protects the testes and sperm against HS induced damage.
Verdet constant determination of dielectric media using a new versatile, portable and low-cost magneto-optical rotator

The full details of a newly developed versatile, portable and low-cost magneto-optical device for the accurate determination of Verdet constant over the wavelength range of 400–480 nm in undergraduate physics and chemistry labs are presented. The elevated sensitivity of the device is achieved by using a semiconducting photodiode detector coupled with an electronic circuit board, which is configured to autonomously record the finest rotation angle in the polarization direction of the transmitted light relative to a reference polarizer. Two different mechanisms to generate a strong coaxial magnetic field of ∼1.34 T are presented, using either a ring neodymium permanent magnet or a solenoid fed by a lithium-ion battery cell. Due to its versatility, portability and low-cost, the presented device is expected to replace most currently existing bulky and expensive setups.
RT-qPCR study of COX-1 and -2 genes in oral surgical model comparing single-dose preemptive ibuprofen and etoricoxib: A randomized clinical trialy

Background This study aimed to evaluate the gene expression of cyclooxygenases (COXs) in an oral model of preemptive analgesia. Material and Methods Gingival tissue was collected during extraction of lower third molars from a randomized, triple-blind, split-mouth and placebo-controlled study. The eligible patients were randomly sorted to receive a single dose either of ibuprofen 400mg, or etoricoxib 120 mg or a placebo, one hour prior to surgery. The temporal course of RNAm was evaluated for COX-1 and -2 by means of a quantitative polymerase chain reaction in real time (RT-qPCR) at time zero and 30 minutes after the surgical procedure began, and it was correlated with clinical parameters (pain and maximum mouth opening). Results There was a significant increase in COX-1 expression between T0 and T30 in ibuprofen (p=0.004) and etoricoxib (p=0.010) groups. As regards COX-2, there were increases from T0 to T30 in all groups (placebo, p=0.012; ibuprofen, p<0.001; etoricoxib, p<0.001). All groups showed a significant decrease in COX-2:COX-1 ratio from T0 to T30 (placebo, p=0.013; ibuprofen, p<0.001; etoricoxib, p=0.047). Experimental groups showed a significant correlation between COX-1 and COX-2 levels and clinical pain parameters. Conclusions The present preemptive analgesia study concludes that COX-2 RNAm induction was directly linked to third molar-related tissue inflammation and that the relation between COX-1 and COX-2 levels were inversely proportional to the preemptively administered nonsteroidal anti-inflammatory drugs COX-2 selectivity. Key words:Preemptive analgesia, dental extraction, cyclooxygenases, real-time polymerase chain reaction.
Pyridine Polyaminocarboxylate Ligands for Use as Actinide-selective Holdback Reagents in Simplified TALSPEAK-like Extraction Systems

ABSTRACT Three pyridine-based aqueous complexants have been synthesized and evaluated for their utility in an unbuffered TALSPEAK (Trivalent Actinide Lanthanide Separation by Phosphorus-reagent Extraction from Aqueous Komplexes) separation system as trivalent actinide-selective holdback reagents. The selectivity was established based on distribution studies using radiotracer 152/154Eu, 241Am, stable Ln, Y, and Th. In this system, these ligands selectively sequester Am from the lanthanides without the need for a secondary pH buffer. Am-lanthanide single-stage separation factors for Eu were found to be >70 for all three ligands and >15 for Nd. The results demonstrate that aqueous pyridine-based ligands represent viable alternatives to conventional aminopolycarboxylate complexants as actinide-selective holdback reagents in TALSPEAK-based actinide-lanthanide separation systems.
Ovarian cystadenofibromas: a three cases report

Cystadenofibroma of the ovary is a rare benign tumor, which begins in the ovarian epithelium; it arises from germ lines and from the ovarian stroma. This tumor can be solid, cystic or semi-solid, depending on the fraction of epithelium and stroma it contains and the secretory activity of the epithelium that composes it. It can be taken for a malignant tumor of the ovary, hence the importance of the per-operative exploration and eventually the extemporaneous examination.
Investigating the change in career decision making self-efficacy levels of university students

The aim of this study is to examine the change in career decision making self-efficacy levels of university students. 29 students from different faculties of a public university in Ankara who chose the “Career Planning in Transition to Business Life” course as a non-departmental selective course constitute the sample of the study. Activities included in the career decision making training program developed by Isik (2010) were used during practice of the course. Career Decision Making Self-Efficacy Scale developed by Ulas & Yildirim (2016) was used as the data collection tool in the pre-test and the post-test, which was performed at the end of the ten week-practice. The data obtained were evaluated in SPSS 18.0 (Statistics Package for Socials Sciences) program, and descriptive statistics, independent groups t-test, dependent groups t test, and bivariate correlation analysis were performed in the analyses of the data. According to the results of the analyses, career decision making self-efficacy scores of students differed significantly in pre-test and post-test measurements, the difference between scores did not vary by gender, and there is no significant correlation between the students’ course grades and pre-test scores, post-test scores or the difference between them.
Temperature and soil nutrients drive the spatial distributions of soil macroinvertebrates on the eastern Tibetan Plateau

Improved knowledge of biological diversity patterns associated with elevation and their driving factors is indispensable for developing ecological theories. However, the results for the elevational distribution patterns of soil fauna are not consistent due to differing climates and vegetation. Here, we present a comprehensive analysis of soil macroinvertebrate composition and structure among different forests at three elevations on the eastern Tibetan Plateau, China. A total of 16,559 individuals belonging to 24 orders and 100 families were collected, and the macroinvertebrate individual abundance, family richness, and diversity apparently increased with increasing elevation. Moreover, remarkable seasonal dynamics were observed for both the composition and functional structure of soil macroinvertebrates among forest types and were inconsistently affected by different environmental factors. The structural equation model suggested that elevation indirectly affected soil macroinvertebrate abundance by modulating climate (e.g., temperature) and soil quality (e.g., soil organic carbon and total nitrogen). Additionally, although vegetation had minor direct effects on soil macroinvertebrate abundance, it might indirectly in ﬂ uence soil macroinvertebrate abundance by regulating plant litter input. Our results indicate that temperature and soil nutrients are critical factors of soil macroinvertebrate elevational distributions and highlight the importance of plant litter input in determining the composition and structure of soil macroinvertebrates at different elevations.
The Occurrence and Some Effects of Raspberry Bushy Dwarf Virus in Red Raspberry1

Raspberry bushy dwarf virus (RBDV) was found in 25 of 75 cultivars maintained in the British Columbia red raspberry (Rubus idaeus L.) breeding program. Crumbly-appearing fruit and leaf abnormalities were associated with infection in some of the cultivars. No RBDV was found in commercial fields of the Willamette cultivar. Comparisons of RBDV-infected and virus-free plants of BC 64-6-68, a selection from the breeding program, showed that the virus reduced yield and fruit size, and increased drupelet abortion resulting in crumbly fruit. RBDV infection did not affect vegetative growth. Field spread of the virus in BC 64-6-68 was through pollen.

Messung und Simulation der Erwärmung von ermüdungsbeanspruchten Betonprobekörpern

Im vorliegenden Beitrag werden Messungen und Berechnungen vorgestellt, die die Temperaturentwicklung in Betonzylindern aufgrund zyklischer Beanspruchung genau beschreiben. Die Messungen wurden in einem Versuchsstand, die Berechnungen im FEM‐Programm ANSYS durchgeführt. Mithilfe der Temperaturmessungen konnten die Simulationen für die Temperaturentwicklung der Betonzylinder mit der verwendeten Betonrezeptur validiert werden. Die Untersuchungen lassen den Schluss zu, dass bei zyklischer Probekörperbelastung und der einhergehenden Probekörperdehnung Energie dissipiert wird und diese maßgeblich für die Erwärmung der Probe verantwortlich ist.
Micronutrient content in the diet of patients in psycho-neurological hospitals in Latvia

Mental health is influenced by a variety of factors, nutrition being one of the most important. Patients in psychiatric hospitals are provided with 24-hour care, including meals, and it is known that nutrition affects the well-being of patients. The intake of micronutrients has been associated with a reduction in depression. The aim of the study was to evaluate patients' diets in Latvian psycho-neurological hospitals according to the micronutrient recommendations provided by the Ministry of Health for the nutritional intake of the Latvian population. All data from the 21 menus provided by three Latvian psycho-neurological hospitals were processed using the Fineli program. Vitamin (B1, B2, B6, B12 and D) and mineral (calcium, iron, iodine, potassium, selenium, and zinc) content was determined for all menus, providing data on the total daily intake of micronutrients. The amount of potassium, selenium and zinc statistically significantly exceeded the recommended intake of trace elements for the population of Latvia. The amount of iron in the menus was found to be higher than that suggested by the national guidelines for men, whereas it was not statistically significantly different than the amount recommended for women. The amount of iodine in the menus was statistically significantly below the recommended level for both men and women. Iodine deficiency was observed in all hospital menus. No significant differences were found in the content of vitamins B2 and B12 for both men and women, whereas vitamins B1 and B6 exceeded Latvian recommendations for women. All hospital menus contained inadequate vitamin D levels in comparison to the established recommendations.
Variation of Coefficient of Friction and Friction Head Losses Along a Pipe with Multiple Outlets

The flow in a pipe having multiple outlets is considered as an advanced problem in hydraulic engineering; many discrepancies were found in the literature, in addition to the lack of experimental and field studies. The main goal of this study is to simulate the flow in a pipe with multiple outlets in order to examine the existing methodologies for estimation of the friction head losses, and to propose a methodology that is based on experimental data. The main physical model in this study consisted of a water supply tank, a pipe with multiple outlets having a piezometer at each outlet. Different pipe diameters were used in this study, the pipe diameters were 25.4 mm (1 in), 38.1 mm (1.5 in), 50.8 (2 in) and 76.2 mm (3 in). The inlet heads used were 1.7 m and 2.2 m. The data collected from different flow conditions were used to assess the variation in the coefficient of friction and friction head losses along the pipe length. It can be concluded that the spacing between any two successive outlets (S) and area ratio (AR = Area of outlet/Area of the main pipe) are the main factors affecting the friction head losses along the pipe. The ratio of total friction head losses along a pipe with outlets having the same properties (length (L), discharge (Q), diameter (d) and material) to a pipe without outlets and having the same properties is called the G factor. The G factor calculated using selected formulae was overestimated in comparison to the calculated G factor obtained from experimental data. For large values of S/d (spacing between outlets/diameter of main pipe), the difference between coefficient of friction in first segment (f1) and last segment (fn) of the multiple outlet pipe was noted to be minimal.

The Prospect of Early Bilingual Education in China

This study will review and analyze literatures of the field to indicate the prospect of the early bilingual education in China. As scientific findings about early bilingualism have few opportunities to be disseminated in China, my investigation aims to introduce some mainstream concepts of bilingual education in the state of art works, and provide more information and implications on the early bilingual field to Chinese parents, educators, and educational policymakers. The essay argues that advanced effectiveness of early bilingual education in improving children’s language proficiency and cognitive competence contribute to a promising prospect in Chinese context. Finally, the findings of this essay are expected to encourage more relevant stakeholders to engage in early bilingual field.
The Formation of Me(AOT)n Micelles as Nanoreactors, Crystallizers, and Charging Agents: Cation-Exchange Solvent Extraction versus Direct Injection Solubilization

ABSTRACT The composition and hydrodynamic diameter of reverse micelles Me(AOT)n (n = 1–3) were determined during injection solubilization of nitrate salts of Li+, Na+, K+, Cs+, NH4 +, Ag+, Ni2+, Co2+, Zn2+, Cu2+, Cd2+, Ca2+, Al3+, Fe3+ , and La3+ cations and upon solvent extraction from their concentrated (1‒2 mol/L) solutions. It was found that solvent extraction by NaAOT reverse micelles can increase the concentration of cations in microemulsion by a factor of 10‒20 as compared to injection solubilization. Therewith, the fraction of super equivalent extraction of cations as nitrate salts into the aqueous cores of reverse micelles can reach 150%. According to the study, the higher is the hydration energy of cation, the greater is the number of successive extraction steps (up to 4) required for a virtually complete (more than 99%) replacement of Na+ in AOT micelles. The hydrodynamic diameter of Мe(AOT)n micelles was in the range from 3.2 to 13.9 nm, and the content of aqueous pseudophase, from 1.2 to 10.4 vol.%. It was demonstrated that the obtained extracts could be used for enhancing the productivity of micellar synthesis of nanoparticles (Ag and CdS) and isothermal micellar crystallization of salts (LiNO3, KNO3, CsNO3 ), and also as the charging agents (Cu(AOT)2, Ni(AOT)2 , and Fe(АОТ)3 ) of SiO2 nanoparticles in the n-hexadecane-chloroform mixture.
