Published: March 2019

Background.Eptifibatide achieves high local concentration via direct intracoronary (I/V) injection as it promotes clot disaggregation, but it remains unclear if it is of superior benefit than the routine intravenous (I/V) administration. Aim. The current study aimed to examine the safety and efficacy of I/C vs I/V bolus regimen dose of eptifibatide during primary percutaneous coronary intervention (PPCI).Material and methods. Prospective, controlled, randomized study enrolled 100 patients with acute anterior ST-segment elevation myocardial infarction (STEMI) eligible for PPCI equally divided into 2 groups (group A received bolus I/C eptifibatide and group B received it I/V) followed by 12-hour continuous I/V infusion. Features related to of myocardial salvage in the form of TIMI flow grade 3, myocardial blush grade 3, ST segment resolution and left ventricular systolic function were evaluated with short-term follow up for 1 month.Results. Mean age of the study population was 50.95±8.45years, there was statistically insignificant difference between both groups regarding baseline characteristics in age (p=0.062), gender (p=0.488), coronary artery disease risk factors (p>0.05), time from onset of pain to admission (p=0.86) or door to balloon (p=0.12). Group A achieved statistically significant better myocardial blush grade 3 (42% vs 10%, p=0.005), ejection faction 30 days after PPCI (46.11±7.81% vs 40.88±6.26%, p=0.005) but statistically insignificant TIMI flow grade 3 (p=0.29) and ST resolution (p=0.34). Incidence of complications in the hospital and 30 days after discharge was statistically insignificant (p>0.05).Conclusion. Both regimens were safe and effective in STEMI patients undergoing PPCI and regimen of I/C bolus eptifibatide achieved better myocardial blush grade and systolic function.

Authors: Shalnova S. A. , Drapkina O. M. 
Published: March 2019

Aim. To compare trends from CVD and cancer mortality in the Russian Federation from 2000 to 2016. depending on age and gender.Material and methods. The official statistics on mortality of Federal state statistics Service and the data obtained in the Russian database of fertility and mortality of the Center for Demographic Studies of the Russian Economic School, Moscow (Russia) were used. Mortality from CVD, including coronary heart disease (CHD), cerebrovascular disease (CerVD), other CVD, and cancer, including prostate cancer in men and breast cancer in women, stomach cancer, trachea, bronchus and lung cancer were analyzed from 2000 to 2016.Results. From 2000 to 2016 CVD mortality leads in comparison with deaths from cancer both in absolute number of deaths and in standardized deaths rates (SDR). There was a decrease in SDR from CVD and cancer between 2003 and 2016, however, rate of decline in the mortality rate from cancer was much less pronounced compared to CVD. At the same time, there is a trend towards a convergence in mortality from both causes in all age groups, with the exception of 75 years and older. For women in the age group of 35–64 years in 2016, the SDR from CVD was slightly lower than from cancer. The decrease in mortality from CVD was accompanied by a decrease in mortality from CHD and the CerVD, the latter was more pronounced in women. The overall mortality rate from cancer was characterized by a decrease in gastric cancer in people of both sexes, trachea, bronchus and lung cancer in men and breast cancer in women and an increase in prostate cancer in men.Conclusion. The ratio of mortality of CVD to cancer and their age characteristics are important for health care. Keeping in mind a present high rate of CVD deaths and cancer deaths rate decline is still not enough, there are now already two big problems for the health care and prevention is a key, especially with common risk factors. These changing trends in mortality may support evidence for changes in the policy of resource allocation in the country.

Published: March 2019

AbstractThis study evaluates the application of Cr(VI) adsorption from the prepared synthetic solution by black sesame (Sesamum indicum L.) seed pulp (BSSP) and chitosan (Cts)-coated black sesame seed pulp beads (Cts-BSSP). BSSP and Cts-BSSP were used as an adsorbent without any chemical or physical treatment to remove Cr(VI) from an aqueous medium. The results indicated that the Cr(VI) removal was pH-dependent and reached an optimum at pH 2.0. It has been observed that the percentage of adsorption increased from 62% to 95% when the amount of Cts-BSSP increased from 0.0125 g to 0.0250 g. The required adsorbent amount for the maximum removal was 0.05 g and 0.1 g for Cst-BSSP and BSSP, respectively. The contact time for the adsorption was 120 min and 90 min for BSSP and Cst-BSSP, respectively. Scanning electron microscopy and Fourier transform infrared spectroscopy were used to explore the possible adsorption mechanism for Cr(VI). The equilibrium data for the BSSP and Cts-BSSP were used with the Langmuir and Freundlich adsorption isotherm models to assess the adsorption capacity and relevant mechanism. The adsorption capacity of the Cts-BSSP for Cr(VI) is relatively high compared to BSSP. The monolayer maximum adsorption capacities for Cr(VI) ions were 31.44 and 18.32 mg/g for Cts-BSSP and BSSP, respectively.

Introduction:
Fenugreek- the seeds of Trigonella foenum-graecum- are known for their medicinal
value since the very early-recorded human history. This study is conducted to explore the effect
of environmental conditions on the trigonelline content of the plant seeds.

Methods:
Trigonelline contents in different samples of fenugreek were estimated by HPTLC. The established
method was proved to be accurate, precise and robust according to ICH guidelines. The used
mobile phase was a mixture of ethyl acetate: methanol: water: formic acid 7.5: 2.5: 3: 1 (%, v/v/v/v) on
20 × 10 cm glass coated silica gel 60 F254 plates. The plates were scanned and quantified densitometrically
at λ = 267 nm after development.

Results:
A valid linear relationship correlating peak area and amount of trigonelline in the range of 100-
700 ng/spot was obtained. The amount of trigonelline varied according to the country of origin.

Conclusion:
The Indian sample has the highest amount of trigonelline followed by the Moroccan sample.
The two locations represent areas with moderate temperature, low altitude and rainy winter.

biological and pharmacological applications in the past few years. These compounds
possess antibacterial, antifungal, anti-inflammatory, analgesic and wound healing activities.
In this study, we report the synthesis of ten hydroxytriazenes in two series derived
from disubstituted aniline and studied for antimicrobial and anti-inflammatory activities.

Methods:
For this purpose, 2-methyl-5-chloroaniline and 2-trifluoromethyl-5-chloroaniline
were used to synthesize compounds A1-5 and B1-5 series, respectively. All compounds
were synthesized by the reported method which involves three steps of the method (i) Reduction,
(ii) Diazotization, (iii) Coupling. All synthesized compounds were characterized
by various techniques CHN elemental analysis, FTIR, 1H NMR, and MASS spectral analysis.
The antibacterial activities of the compounds were screened against S. aureus, S.
pyogenes, E. coli, P. aeruginosa, and antifungal activities were against C. albicans, A.
clavatus by the zone of inhibition method. In addition, anti-inflammatory activity was also
evaluated by carrageenan-induced paw edema method and results were reported as % inhibition.

Results:
All the synthesized compounds were obtained in pure form and their spectral data
are in good agreement with their structure. The synthesized compounds have shown good
antimicrobial activity and zone of inhibition was ranging 21 to 24 mm. Further antiinflammatory
effect of the compounds was 96.58 to 98.71 % inhibition.

Conclusion:
The results of the present study indicate that chloro and trifluoromethyl substitution
at hydroxytriazenes skeleton could improve anti-inflammatory and antimicrobial
activities.

Published: March 2019

Background:
To predict the future health situation of a nation or a state, the Time Series
Predictive Modelling is a valuable tool in the health system. In order to attain the Millennium Development
Goals (MDGs) for MMR in India, the purpose of this research work is to identify the
trends in the essential components, which are responsible for maternal death prevention.

Methods:
To achieve the above-mentioned objective we have evaluated the performance of three
different approaches in our process model for Time Series Predictive Modelling on public maternal
health data. The first approach is Exponential Smoothing method i.e. is a statistics based method,
the second one is Multi Layer Perceptron method i.e. a machine learning based method and the
third one is Long Short Term Memory network i.e. a deep learning method. For the data analysis,
the five years’ monthly time series data (2012 to 2017) of Uttar Pradesh state of India is collected
from NRHM portal of Indian Government. It is partitioned into training data for modeling and testing
data for validation of the model.

Results:
The major components from the original data are selected by using an attribute selection
method i.e. greedy approach based Best-First Wrapper method. The MAPE statistical parameter is
used to define the accuracy level of the predictive values for the selected dimensions of the given
data. A performance-based comparison of all applied approaches is presented at last which illustrates
that exponential smoothing method has performed better than the other two methods.

Conclusion:
The presented trend analysis and future values generated by using the presented process
model will feed input in the decision making for planning better healthcare services.

Authors: Muzykiewicz Anna , Zielonka-Brzezicka Joanna , Klimowicz Adam 
Published: March 2019

Summary

Introduction: Quince (Cydonia oblonga Mill.) is a plant of which both the fruits and the leaves are sources of compounds with antioxidant potential. Such activity could be helpful to prevent the development of so-called oxidative stress.

Objective: The aim of the study was to evaluate the antioxidant properties of ethanolic, methanolic and acetonic extracts of mature and immature quince fruits, as well as leaves.

Methods: The extracts were prepared using ultrasound-assisted extraction, for 15, 30 and 60 minutes. The antioxidant activity was assessed by DPPH, FRAP, ABTS and Folin-Ciocalteu (F-C) methods.

Results: Antioxidant activity of all of the evaluated extracts were observed. The highest potential determined with each method was found for leaf extracts. Moreover, higher activity of unripe fruit extracts compared to ripe fruit was observed. Taking into account the applied extractants, the highest antioxidant capacity was found for methanolic extracts, extracted for 60 and 30 minutes. By contrast, the lowest potential was observed mainly for ethanolic extracts (extraction time 15 minutes).

Conclusion: Quince extracts, particularly alcoholic extracts of leaves, seem to be a valuable source of anti-oxidants. Factors as extraction time, the type of solvent and degree of fruit maturity may influence the antioxidant activity of extracts.

Published: March 2019

Abstract
Nanocomposite silica thin films made using the sol-gel method were studied. The nano-silica films were prepared using a mixture of tetraethyl orthosilicate (TEOS), deionized water, ethanol, and ammonia solution. To control the growth of the particles inside the film, the nanocomposite silica film was prepared using a mixture of the nano-silica sol and the silica sol. The change in the particle size with the heat treatment temperature ranging from 450 °C to 1100 °C was investigated. X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), NKD (refractive index-N, extinction coefficient-K, and thickness-D) and ultraviolet-visible (UV-Vis) spectrophotometry were used for characterization purposes. The XRD studies showed that the nano-silica thin films were amorphous at all annealing temperatures except for 1100 °C. The_-cristobalite crystal structure formed at the annealing temperature of 1100 °C. Optical parameters, such as refractive indices and extinction coefficients, were obtained using the NKD analyzer with respect to the annealing temperature of the films. The activation energy and enthalpy of the nanocomposite silica film were evaluated as 22.3 kJ/mol and 14.7 kJ/mol, respectively. The cut-off wavelength values were calculated by means of extrapolation of the absorbance spectra estimated using the UV-Vis spectroscopy measurements. A red shift in the absorption threshold of the nanocomposite silica films indicated that the size of the silica nanoparticles increased with an increase of the annealing temperatures from 450 °C to 900 °C, and this confirms the quantum confinement effect in the nanoparticles.
Research on energy absorption properties of open-cell copper foam for current collector of Li-ions
Authors: Chen Jian , Li Xiongfei , Li Wei , Li Cong , Xie Baoshan , Dai Shuowei , He Jian-Jun , Ren Yanjie 
Published: March 2019

Abstract
Quasi-static uniaxial compressive tests of open-cell copper (Cu) foams (OCCF) were carried out on an in-situ bi-direction tension/compress testing machine (IBTC 2000). The effects of strain rate, porosity and pore size on the energy absorption of open-cell copper foams were investigated to reveal the energy absorption mechanism. The results show that three performance parameters of open-cell copper foams (OCCF), involving compressive strength, Young modulus and yield stress, increase simultaneously with an increase of strain rate and reduce with increasing porosity and pore size. Furthermore, the energy absorption capacity of OCCF increases with an increase of porosity and pore size. However, energy absorption efficiency increases with increasing porosity and decreasing pore size. The finite element simulation results show that the two-dimensional stochastic model can predict the energy absorption performance of the foam during the compressive process. The large permanent plastic deformation at the weak edge hole is the main factor that affects the energy absorption.

Published: March 2019

Abstract
The use of crumb rubber in the modification of asphalt has occurred because of the problems related to disposal of scrap tires. However, the use of scrap tires in asphalt pavements, known as asphalt rubber pavements, can minimize environmental impacts and maximize conservation of natural resources. The textile fibers from recycled tires are typically disposed of in landfills or used in energetic valorization, but similar to other fibers, they can be used as a valuable resource in the reinforcement of engineering materials such as asphalt mixtures. Thus, this work aims at studying the use of textile fibers recycled from ground tires in the reinforcement of conventional asphalt mixtures. The application of textile fibers from ground tires was evaluated through laboratory tests on specimens extracted from slabs produced in the laboratory. Indirect tensile tests were performed on a series of nine asphalt mixtures with different fiber and asphalt contents and compared with a conventional mixture. The results obtained from a 50/70 pen asphalt were used to define three asphalt mixture configurations to be used with 35/50 pen asphalt. The results indicate that the textile fibers recycled from used tires can be a valuable resource in the reinforcement of asphalt mixtures.
