Tüketim kavramı, tüketmek fiilinden
türediği için olumsuz çağrışım yapar. Fakat tüketim, tarihin her döneminde
medeniyetleri maddi olarak beslemiştir de. İnsanoğlu nasıl makineleri icat edip
mekanik işleyişini kurguladıysa, günümüz toplum yapısı da sanayi devriminden bu
yana mekanik bir şekilde kendini biçimlendirmiştir. Bugün var olan tüketim
toplumu bizatihi o gün tohumları atılan üretim biçimlerinin neticesidir.
Kitlesel üretim beraberinde kitlesel tüketme zorunluluğunu getirmiş, buna bağlı
olarak tüketim topluma dayatılmıştır. Tüketim kültüründe sürekli üretmek
durumunda kalan sanatçı ise, seri haldeki birbirine benzer sanat çalışmalarıyla
piyasanın hızına ayak uydurmaya çalışmaktadır. Aslında tüm bunlar sanat
nesnesinin tüketim nesnesine nasıl dönüştüğü hakkında fikir verir. Peki, sanat

gelmiştir?

Sanatsal üretimin tüketim nesnesine evrilmesi sürecini kapsayan bu
makale, konusu gereği belirli sanatçıları, yapıtları işaret etmektedir. Bu
sınırlılık içinde, sanat eserinin tüketim nesnesi olarak sunumu, sanatın

Cardioprotective Potential of Iron Chelators and Prochelators
Authors: Jansová Hana , Šimůnek Tomáś
Published: March 2019

Heart is a particularly sensitive organ to iron overload and cardiomyopathy due to the excessive cardiac iron deposition causes most deaths in disorders such as beta-thalassemia major. Free or loosely bound iron ions readily cycle between ferrous and ferric states and catalyze Haber-Weiss reaction that yields highly reactive and toxic hydroxyl radicals. Treatment with iron chelators (desferrioxamine, deferiprone, and deferasirox) substantially improved cardiovascular morbidity and mortality in iron overloaded patients. Furthermore, iron chelators have been studied in various cardiovascular disorders with known or presumed oxidative stress roles (e.g., ischemia/reperfusion injury) also in patients with normal body iron contents. The pharmacodynamic and pharmacokinetic properties of these chelators are critical for effective therapy. For example, the widely clinically used but hydrophilic chelator desferrioxamine suffers from poor plasma membrane permeability, which means that high and clinically unachievable concentrations/doses must be employed to obtain cardioprotection. Therefore, small-molecular and lipophilic chelators with oral availability are more suitable for this purpose, particularly in states without systemic iron overload. Apart from agents that are already used in clinical practice, aroylhydrazone iron chelators, namely salicylaldehyde isonicotinoyl hydrazone (SIH), have provided promising results. However, the use of classical iron-chelating agents is associated with a risk of toxicity due to indiscriminate iron depletion. Recent studies have therefore focused on "masked" prochelators that have little or no affinity for iron until site-specific activation by reactive oxygen species.
The Role of Genetic Polymorphism in the Formation of Arterial Hypertension, Type 2 Diabetes and their Comorbidity
Authors: Shalimova Anna , Fadieienko Galyna , Kolesnikova Olena , Isayeva Anna , Zlatkina Vira , Nemtsova Valeriya , Prosolenko Kostyantyn , Psarova Valentyna , Kyrychenko Natalia , Kochuieva Maryna
Published: March 2019

Background:

Hereditary component plays a significant role in the formation of insulin resistance (IR)
- one of the pathogenetic links of arterial hypertension (AH) and type 2 diabetes mellitus (DM2). However, the
genetic predisposition to IR can not be realized and does not manifest itself clinically in the absence of appropriate
factors of the environment (excessive nutrition, low physical activity, etc.).

Objective:

The review summarizes the results of studies which describe the contribution of genetic polymorphism
to the formation and progression of AH, DM2 and their comorbidity in various populations.

Results:

In many studies, it has been established that genetic polymorphism of candidate genes is influenced by
the formation, course and complication of AH and DM2. According to research data, the modulating effect of
polymorphism of some genetic markers of AH and DM2 on metabolism and hemodynamics has been established.
The results of numerous studies have shown a higher frequency of occurrence of AH and DM2, as well as their
more severe course with adverse genetic polymorphisms. At the same time, the role of genetic polymorphism in
the formation of AH and DM2 differs in different populations.

Conclusion:

Contradictory data on the influence of gene polymorphisms on the formation of AH and DM2 in
different populations, as well as a small number of studies on the combined effects of several polymorphisms on
the formation of comorbidity, determine the continuation of research in this direction.
Molecular Dynamics Simulations of Glycyrrhizic Acid Aggregates as Drug-Carriers for Paclitaxel
Authors: Hussain Mumtaz
Published: March 2019

Background:

Glycyrrhizic acid (GA) is a glycoside that has shown considerable promise as a
penetration enhancer and drug carrier to improve the absorption of poorly water-soluble drugs. The
aggregation behavior of GA and its ability to form large micelles at higher solution concentrations are
thought to contribute to these bioavailability enhancing properties. The oral absorption of Paclitaxel
(PTX) for example, an anti-cancer agent which exhibits poor oral bioavailability, has been found to
significantly increase in the presence of GA.

Methods:

In an attempt to visualize the aggregation behavior of GA and its subsequent association with
PTX, 100 ns molecular dynamics simulation of a 5 mM aqueous solution of GA with 10 molecules of
PTX was conducted using GROMACS and an all-atom forcefield.

Results:

Aggregation of GA molecules was found to occur quickly at this level of saturation leading to
two stable aggregates of 13 and 17 GA molecules with an effective radius of 10.17 nm to 10.92 nm.
These aggregates form not in isolation, but together with PTX molecule embedded within the structures,
which reduces the number of interactions and hydrogen-bonding with water.

Conclusion:

GA aggregation occurs around PTX molecules in solution, forming co-joined GA-PTX
cluster units at a ratio of 3:1. These clusters remain stable for the remainder of the 100ns simulation and
serve to isolate and protect PTX from the aqueous environment.

Authors: Genç Hasan , Taşdemir Volkan , Tozlu İsrafil , Ögün Erdal
Published: March 2019

Synthesis of pyrazole-3-carboxylic acid was progressed via two different protocols, one of
which is solid state. Pyrazole-3-carboxylic acid was converted into different derivatives such as ester,
urea, amide and nitrile. The amide compound was converted to nitrile using SOCl2 and DMF. Solid
state heating of carboxylic acid gave decarboxylated product. Cyclization of tetra-substituted pyrazole
with hydrazines resulted in pyrazolopyridazinones. The antimicrobial activities of the synthesized pyrazole
derivatives against Bacillus cereus, Escherichia coli, Micrococcus luteus, Staphylococcus aureus,
and Saccharomyces cerevisiae were evaluated. One of the pyrazole derivatives which possess nitro group
showed antimicrobial activity in only B. cereus, a Gram-positive bacteria, with an MIC of 128 μg/mL.

Authors: Moghadam Ebrahim S. , Tehrani Maryam H. , Csuk René , Fischer Lucie , Faramarzi Mohammad Ali , Rashidi Arezoo , Javadi Iraj , Amini Mohsen
Published: March 2019

Background:

During last recent years number of anti-tubulin agents were introduced for treatment of
diverse kind of cancer. Despite of their potential in treatment of cancer, drug resistance and adverse toxicity
such as peripheral neuropathy are some of the negative criteria of anti-tubulin agents.

Methods:

Twenty seven quinazoline derivatives were synthesized using a multicomponent reaction. The cytotoxicity
of compounds 1-27 was tested in SRB assays employing five different human tumor cell lines. Effect of
two of active compounds on tubulin polymerization was also checked using a commercially available assay kit.
Molecular modelling studies were also performed using autodock tools software.

Results:

SRB assays showed that compounds 2, 9, 16 and 26, being highly cytotoxic with IC50 values ranging
between 2.1 and 14.3µM. The possible mode of action of compounds, 2, 9, 16 and 26, and the taxol binding site
of the protein tubulin, an important goal for antimitotic drugs, was also studied by molecular docking, which
showed reasonable interactions with tubulin active site, followed by investigation of the effects of compounds 9
and 16 on the polymerization of tubulin. The results showed the tested compounds to be highly active as inducers
of tubulin polymerization.

Conclusion:

Altogether, with respect to obtained results, it is attractive and beneficial to further investigation on
quinazoline scaffold as antimitotic agents.
Following Carbon Dioxide Concentration and Consequences of its Zero Emission on the Environmental Ecosystem
Authors: El-Meligi Amin A.
Published: March 2019

Background:

This research aims to follow the concentration of carbon dioxide (CO2)
in the atmosphere and the effect of zero-emission on the ecosystem. CO2 is the most important of
the green house gases. Nowadays, the earth is suffering from global warming due to greenhouse
gases. The call all over the world is to reduce the emission of the greenhouse gases, mainly CO2.

Methods:

The research methodology depends on the data of international research laboratories,
which follow the concentration of CO2, such as National Oceanic and Atmospheric
Administration (NOAA), the USA, and Mauna Loa Observatory in Hawaii. The concern towards
CO2 concentration in the atmosphere started in the last century.

Results:

The industrial revolution did not consider the impact of pollution on the environment.
The impact on the environment was noticed only after a clear disturbance in the ecosystem. The
emission of greenhouse gases, especially, CO2 is monitored; daily, monthly and yearly. There are
different sources of CO2 emissions, such as transportation, factories, burning of forests etc. In
fact, CO2 is a harmful as well as a useful gas. It is harmful because of global warming, and useful
because of its important role in the photosynthesis process. This process is very crucial for all
living things. The research to reduce the emission of CO2. has provided some solutions. Layered
materials, MPS3, where M stands for the transition metal, have been used to store hydrogen gas.
The hydrogen molecule size is 2.89 Å, and the molecular size of CO2 is 3.3 Å, this means that the
CO2 can be captured by the layered materials. The capturing of CO2 is achieved by simulation.

Conclusion:

We need to reduce the emission of CO2 but not to reach zero emission, because
then, there will be no photosynthesis process, which means there will be no life on the earth.
Carbon capture and storage is a technology that can capture up to 90% of the CO2, but the biggest
obstacle to this approach lies in the inherent thermodynamic stability and kinetic inertness of
CO2.

Pengaruh Penambahan Laurat dan Glisin terhadap Nilai Warna dan Kadar Sitrinin Angkak
Authors: Ristiarini Susana , Cahyanto Muhammad Nur , Widada Jaka , Rahayu Endang Sutriswati
Published: March 2019

Angkak, commonly used for food colorant and flavor enhancers in oriental cuisine, is the result of fermentation by Monascus purpureus on steamed rice. In addition to producing pigments Monascus purpureus, Angkak also produces mycotoxins, citrinin, which is hepato-nephrotoxic. Biosynthesis of pigment and citrinin is following a polyketide synthase pathway and then subdivides to form pigment or citrinin. Fatty acids and amino acids are known to be the precursors of red pigment formers in their biosynthetic pathways. The purpose of this research was to know the effect of addition of lauric fatty acid and amino acid glycine on steamed rice substrate to the color characteristic and citrinin level by M. purpureus JK9A. The amount of fatty acid and glycine was respectively 0.5% and 1% (w/w). Fermentation was carried out for 14 days and every two days the solids content of fermented products, pH, number of cells, colors, pigments dissolved in water were measured. The level of citrinin was tested at the end of the fermentation period (14th day). There was no significant difference between treatments for the solids content of about 23  ̶  29% and the number of cells 6.32  ̶  6.56 logCFU/g. While the pH value, color and water-soluble pigments were significantly different between treatment and control. The ˚hue values of glycine and combination of lauric-glycine were 16.11 and 15.33, respectively, lower than controls (22.76). The highest A500nm/A400nm ratio was in the combination treatment of lauric-glycine and the lowest levels of citrinin also in the treatment of lauric-glycine combination. This study noticed that the addition of lauric or glycine and its combination in rice media for Monascus purpureus JK9A fermentation proved to increase the biosynthesis of red pigment (46.34%) and decrease citrinin level up to 49.97%.

Regional and local toponyms in Serbian, Croatian, Bulgarian and Czech phraseology
Authors: Krejcí Pavel
Published: March 2019

The comparative method allows us to make remarkable conclusions. In the
examples, it is obvious that there is often an universal model of
phraseology used in several national societies and which shows differences
exclusively in the toponymic component (Serb./Croat. mirna XTOP,
Serb./Croat./Bulg. proci kao XANTHROP na YTOP?). On the other hand, we can
reveal a model that is associated only with a certain national community,
with its language, and for which there is no analogy in another, although
neighboring language (Bulg. XANTHROP ot YTOP in the sense of ?I do not know
who?). The toponymic component (or what it represents) can be in a direct
motivational connection with the meaning of the phraseme (Kosovo, Chlumec),
where without some cultural-historical education or knowledge, certain
phrasemes cannot be correctly interpreted (decoded). There are, however,
cases where the toponymic component may have no connection with the meaning
of the phraseme in which it is a part - an example of this is the Czech
collocation vrabci z Cech or the Bulgarian kum Dusan ot Nis.
Mechanical characterization of copper coatings electrodeposited onto different substrates with and without ultrasound assistance

Published: March 2019

The mechanical properties of systems consisting of copper coatings electrodeposited on both brass sheet (BS) and thick electrodeposited nickel coating (ED Ni) substrates have been investigated. The electrodeposition of copper coatings was performed with and without the ultrasound assistance. The ultrasound application decreases root mean square (RMS) roughness of deposited Cu coating on both applied substrates, as obtained from non-contact AFM measurement. The coating roughness is highly dependent on the substrate roughness, being the smallest for the Cu coatings deposited on ED Ni substrate with the ultrasound mixing. The hardness and adhesion properties were characterized using the Vickers microindentation test. Model of Korsunsky was applied to the experimental data for determination the film hardness and the model of Chen-Gao was used for the adhesion evaluation. The introduction of ultrasonic agitation caused the changes in the film microstructure, and consequently in the mechanical properties. The copper coatings on both substrates, have higher hardness when deposited from electrolyte with ultrasound agitation. Although the type of the substrate has the major influence on the adhesion strength, it can be said that Cu electrodeposition with ultrasonic mixing contributes to an increase in adhesion.
