Published: March 2018

SUMMARY

Objectives:
The aim of this prospective randomized multicenter clinical trial was to evaluate the survival rate of glass fiber–reinforced posts cemented with self-adhesive or regular resin cements.

Methods:
The sample was comprised of 152 teeth randomized within two centers and in accordance with the adhesive strategies for RelyX U100/U200 (3M ESPE) or Single Bond and RelyX ARC (3M ESPE). The cementation procedures were standardized and performed by previously trained operators. The primary outcome evaluated was post debonding. A trained evaluator, one for each center, assessed all subjects at intervals of 12 months for up to 6 years. Statistical analysis was performed using the Kaplan-Meier method.

Results:
There was no statistically significant difference in survival rates between the two strategies assessed (p=0.991), with a 92.7% survival rate for the self-adhesive cement and 93.8% for the regular cement.

Conclusion:
Both the self-adhesive and the regular resin cements are good alternatives for glass fiber post cementation.

The purpose of this research is to determine the most effective of nutmeg meat products to inhibit the specific spoilage bacteria based on inhibitory zone and determine the power of antibacterial compounds in nutmeg meat to inhibit and kill specific spoilage bacteria based on the number of growth of spoilage bacteria. This research consists of two stages: The purpose of first stage is to determine the most effective of nutmeg meat products as an antimicrobial agent to inhibit gram-positive and gram-negative bacteria with inhibition test response. The second stage of the main research continued from preliminary research that consists of three steps. The purpose of first step is to determine the best long immersion antimicrobial substances against bacteria growth in fresh meat for 0 minute, 5 minutes, 10 minutes, 15 minutes and 20 minutes. The purpose of second step is to determine the correlation between the concentration of antimicrobial agent 5%, 10%, 15%, 20% and 25% of the microbial growth number in fresh meat stored within 5 days. The analysis was performed using total plate count method. The purpose of third step is to determine the level of concentration that is acceptable to consumers. Based on the results of research was obtained that the nutmeg meat essential oil can inhibit the growth of gram positive and negative bacteria. If concentration of antimicrobial substances are higher, so that the power of inhibit to against spoilage bacteria in fresh meat is higher. The selected concentration by organoleptic test that acceptable by consumers is 10%.

La presencia y distribución de los hablantes de la lengua maya yucateka en la Península de Yucatán del clásico temprano hasta el momento de contacto con los españoles son estudiadas mediante un análisis de las inscripciones jeroglíficas bajo los planteamientos de la teoría de la semiótica integracional. Siendo la lengua escrita un producto cultural que sirve como medio de comunicación alterno a la lengua hablada, una hipótesis que plantea que una lengua hablada en cierta área geográfica tiende a dejar sus rasgos particulares en el código de las inscripciones debe de considerar, aparte de los aspectos lingüísticos de la lengua bajo estudio, los factores biomecánicos, macrosociales y circunstanciales que interfieren en su manifestación gráfica-visual. Complementando los avances de la lingüística histórica y epigrafía o gramatología en el campo de los jeroglíficos mayas con la información lingüística, geográfica, histórico-cultural y social documentada en las fuentes coloniales, se elabora una propuesta integral para el proceso de la expansión de los hablantes del maya yucateko en la época prehispánica.

Abstract
Central sleep apnea (CSA) is a disease characterized by repetitive episodes of the socalled central apneas during sleep. The disease has a very complex etiology. In clinical practice, the most important causes of CSA are disorders of the central nervous system, congestive heart failure or certain pathological changes of the respiratory muscles. We present a case of a 43-year-old male with severe CSA, who was successfully treated with BiPAP ST equipment.

Authors: Koszuta Agnieszka , Szymanska Jolanta 
Published: March 2018

Abstract
Social, economic and technological progress results in an increasing range of treatment and rehabilitation methods for patients with partial or complete edentulism. The role of the dentist is to inform the patient about the full range of available missing teeth treatment options leading to complete rehabilitation of the masticatory organ in agreement with the patient’s aesthetic and functional expectations. The aim of the paper was to identify the type of prostheses used by patients before opting for implantsupported teeth replacements, according to the patients’ age, sex, marital status, place of residence and education. The study covered 464 patients, women and men, aged 20-74, treated with dental implants. The patients answered questions in an anonymous questionnaire. The influence of the prosthetic replacement type according to age and marital status was highly statistically significant, whereas it was statistically significant according to sex, place of residence and education. The female respondents who previously used tissue-borne complete or partial dentures opted for implant treatment more frequently. The respondents younger than 40 and between 40-60 years of age who did not previously used any prosthetic replacements opted for implant treatment more frequently. The respondents who did not use any prosthetic replacements decided to undergo implant treatment most frequently, regardless of their marital status, education and place of residence. The patients opted for implant treatment to improve their quality of life, despite the high cost of such therapy.

Abstract
Considering the nutritional values, breadstuff plays a big part in covering human nourishment needs and constitutes a base of all day diet. Moreover, bread is an excellent source of numerous vitamins and minerals the abundance of which depends on the degree of grinding. Thus, it seems to be very important to know the composition and level of bio-elements. That is why the main target of this study was to evaluate the concentration of selected trace elements: chromium (Cr), nickel (Ni), iron (Fe) and manganese (Mn) in wheat grain, wheat bran, different wheat and rye flour types and variety of breadstuff also with addition of grains and seeds from different bakeries and mills. Another task was to analyze if the technological process has an influence on secondary despoil of bread goods with heavy metal elements. The analyzed trace elements were measured with a precise and accurate atomic absorption spectrophotometric method (AAS) and the results were expressed in mg/kg of selected sample. Obtained results show that bread and grain products are a good source of trace elements like chromium, nickel, iron and manganese. However, the higher levels of chromium and nickel in bread goods could rather be an effect of impurity caused by a technological process in mill and bakeries.
Zero crossing and ratio spectra derivative spectrophotometry for the dissolution tests of amlodipine and perindopril in their fixed dose formulations
Authors: Maczka Paulina , Gumieniczek Anna , Galeza Justyna , Pietras Rafal 
Published: March 2018

Abstract
Dissolution tests of amlodipine and perindopril from their fixed dose formulations were performed in 900 mL of phosphate buffer of pH 5.5 at 37°C using the paddle apparatus. Then, two simple and rapid derivative spectrophotometric methods were used for the quantitative measurements of amlodipine and perindopril. The first method was zero crossing first derivative spectrophotometry in which measuring of amplitudes at 253 nm for amlodipine and 229 nm for perindopril were used. The second method was ratio derivative spectrophotometry in which spectra of amlodipine over the linearity range were divided by one selected standard spectrum of perindopril and then amplitudes at 242 nm were measured. Similarly, spectra of perindopril were divided by one selected standard spectrum of amlodipine and then amplitudes at 298 nm were measured. Both of the methods were validated to meet official requirements and were demonstrated to be selective, precise and accurate. Since there is no official monograph for these drugs in binary formulations, the dissolution tests and quantification procedure presented here can be used as a quality control test for amlodipine and perindopril in respective dosage forms.

Published: March 2018

Abstract
Due to high amount of collagen fibres in the structure of bone, the enzymes capable of collagen digestion play a key role in bone remodelling. Matrix metalloproteinases (MMPs), prevailing extracellular endopeptideses, can digest extracellularly located proteins, e.g. collagen, proteoglycans, elastin or fibronectin. Among MMPs, collagenases (MMP-1, MMP-8 and MMP-13) and gelatinases (MMP-2 and MMP-9) can cleave collagen particles to forms that are able to undergo further steps of catabolism intracellularly. In addition, activity of the gelatinases (as an activation of proinflammatory cytokines) facilitates spreading inflammation that is necessary during the first stage of bone healing. Further studies related to the role of various MMPs in mandibular fractures should precisely explain their function in the bone healing and evaluate the influence of MMPs inhibitors on that process. This review provides the basic information about two groups among MMPs family, collagenases and gelatinases, and their role in repairing processes after mandibular fractures.

Authors: Paradowska Katarzyna , Lutek Joanna , Ginalska Grazyna 
Published: March 2018

Abstract
The quest for new techniques for screening inhibitors of phosphoglucose isomerase is crucially important owing to therapeutic control of chronic bacterial infections associated with the biosynthesis of bacterial biofilm. According to the new method, yellowish zones against the purple background could be visually observed where phosphoglucose isomerase activity was inhibited. The new protocol with NADPH/NBT/PMS staining for TLC-autographic method was able to detect PGI inhibition by pure reference substance as mercury(II) chloride.

Local Economic Governance and the Development of the Business Sector in Vietnam
Authors: Thuy Dao Thi Bich 
Published: March 2018

Abstract:Local economic governance plays an important role in the development of the business sector. To assess its impact on business sector growth in Vietnam, this empirical study is conducted at the local level with all 63 provinces nationwide in the period from 2006 to 2014. The Provincial Competitiveness Index (PCI) is used as a measurement for local economic governance. The finding reveals that overall the PCI has a positive effect on growth in the number of enterprises and output generated in the business sector. At the sub-index level, 5 indicators show positive effects with labor training having the largest impact, followed by time costs of regulatory compliance, informal charges, transparency and finally business support service. Land access and security of tenure and proactivity of the provincial leadership unexpectedly show negative effects while the other 2 indicators, including entry cost for new firms and legal institutions, have no significant impact on business sector growth.

Authors: Ivanov Michael , Usenko Natalia , Kotova Natalia 
Published: March 2018

AbstractThe enthalpies of mixing in liquid alloys of the binary Mn–In and ternary Mn–In–Gd systems were determined over a wide range of compositions by means of isoperibolic calorimetry in the temperature range 1 500 – 1 650 K. The enthalpies of mixing in the Mn–In system demonstrate endothermic effects (ΔHmax = 4.66 ± 0.38 kJ · mol−1 at xIn = 0.40). The enthalpies of mixing in the liquid ternary Mn–In–Gd alloys were determined along six sections (xMn/xIn = 0.22/0.78; 0.44/0.56; 0.65/0.35 and 0.83/0.17 for xGd changed from 0 up to 0.5 and xMn/xGd = 0.30/0.70; 0.60/0.40 for xIn changed from 0 up to 0.3). Enthalpies of mixing in the ternary system were found to be predominantly exothermic and steadily increasing in absolute values towards the Gd–In boundary binary system, reaching the maximum value in the vicinity of the phase GdIn.

OBJECTIVEThe authors present long-term follow-up data on patients treated with Gamma Knife radiosurgery (GKRS) for acoustic neuroma.METHODSSix hundred eighteen patients were radiosurgically treated for acoustic neuroma between 1992 and 2016 at the Department of Neurosurgery, Medical University Vienna. Patients with neurofibromatosis and patients treated too recently to attain 1 year of follow-up were excluded from this retrospective study. Thus, data on 557 patients with spontaneous acoustic neuroma of any Koos grade are presented, as are long-term follow-up data on 426 patients with a minimum follow-up of 2 years. Patients were assessed according to the Gardner-Robertson (GR) hearing scale and the House-Brackmann facial nerve function scale, both prior to GKRS and at the times of follow-up.RESULTSFour hundred fifty-two patients (81%) were treated with radiosurgery alone and 105 patients (19%) with combined microsurgery-radiosurgery. While the combined treatment was especially favored before 2002, the percentage of cases treated with radiosurgery alone has significantly increased since then. The overall complication rate after GKRS was low and has declined significantly in the last decade. The risk of developing hydrocephalus after GKRS increased with tumor size. One case (0.2%) of malignant transformation after GKRS was diagnosed. Radiological tumor control rates of 92%, 91%, and 91% at 5, 10, and 15 years after GKRS, regardless of the Koos grade or pretreatment, were observed. The overall tumor control rate without the need for additional treatment was even higher at 98%. At the last follow-up, functional hearing was preserved in 55% of patients who had been classified with GR hearing class I or II prior to GKRS. Hearing preservation rates of 53%, 34%, and 34% at 5, 10, and 15 years after GKRS were observed. The multivariate regression model revealed that the GR hearing class prior to GKRS and the median dose to the cochlea were independent predictors of the GR class at follow-up.CONCLUSIONSIn small to medium-sized spontaneous acoustic neuromas, radiosurgery should be recognized as the primary treatment at an early stage. Although minimizing the cochlear dose seems beneficial for hearing preservation, the authors, like others before, do not recommend undertreating intracanalicular tumors in favor of low cochlear doses. For larger acoustic neuromas, radiosurgery remains a reliable management option with tumor control rates similar to those for smaller acoustic neuromas; however, careful patient selection and counseling are recommended given the higher risk of side effects. Microsurgery must be considered in acoustic neuromas with significant brainstem compression or hydrocephalus.
