Authors: Levdanskiy Vladimir Aleksandrovich , Levdanskiy Aleksandr Vladimirovich , Kuznetsov Boris Nikolayevich
Published: December 2022

The yields of proanthocyanidins isolated from the initial and deresinated (extracted with hexane) bark of the Siberian cedar (Pínus sibírica) by water, 15% water-ethanol solution and ethyl acetate in a Soxhlet apparatus were compared. It was shown, that the preliminary removal of resinous substances from the cedar bark does not affect the yields of proanthocyanidins extracted with water and 15% water-ethanol solution (for the initial bark is 0.44% (wt.) and 0.57% (wt.) and for the deresinated bark is 0.43% (wt.) and 0.57% (wt.), respectively). It was established that the extraction of deresinated bark with ethyl acetate makes it possible to increase the yield of proanthocyanidins about 2 times to 1.04% (wt.). The composition of the proanthocyanidins isolated from the cedar bark was characterized by UV, FTIR, and 13C NMR spectroscopy methods. The flavonoids cyanidin and delphinidin were identified using the conversion proanthocyanidins to anthocyanidins. The proanthocyanidins isolated from cedar bark mainly consist of procyanidin and prodelphinidin, regardless of the method of their isolation – extraction by water, 15% aqueous ethanol solution or ethyl acetate. It was established that the proanthocyanidins isolated from the bark of cedar, in contrast to those isolated from the bark of pine (Pinus maritima) and (Pinus radiata), contain gallic acid residues.

Published: December 2022

The work is devoted to the study of the phytochemical composition of subcritical extracts of the underground part of high aconite (Aconitum septentrionale L.). The samples of roots and rhizomes of Aconitum septentrionale grown in the Republic of Altai were studied. The quality characteristics of plant biomass were determined: moisture content, ash content, quantitative content of biologically active substances extracted by methods of sequential extraction and sequential processing of plant materials under subcritical conditions. The group composition of biologically active substances of Aconitum septentrionale has been established. The quantitative content of biologically active substances of alkaloid nature isolated from the roots and rhizomes of Aconitum septentrionale by different methods was determined. It is shown that the content of alkaloids extracted under subcritical conditions for 2 hours is higher than those extracted by maceration for 16 hours. A recipe has been developed for creating a cream-gel based on extracts of Aconitum septentrionale extracted in various ways. The physico-chemical parameters were analyzed and the effectiveness of cream-gels developed using extracts obtained by various methods from the roots and rhizomes of high aconite was revealed. The data presented in the article are of interest for the creation of biopreparations based on extracts of Aconitum septentrionale, promising for use in the pharmaceutical industry.

Published: December 2022

INTRODUCTION:

We aimed to evaluate the real-world effectiveness and safety of tofacitinib for the treatment of ulcerative colitis (UC).

METHODS:

REMIT-UC is a Canadian multicenter cohort study. Standardized data collection was performed on 334 consecutive adult outpatients with UC treated with tofacitinib. The primary outcomes were achievement of clinical and endoscopic remission. Safety outcomes were reported using incidence rates (events/100 patient-years of exposure). A multivariable Cox proportional hazards model was used to evaluate predictors of loss of response after tofacitinib dose de-escalation to 5 mg twice daily (BID).

RESULTS:

Clinical remission was achieved by 35.3% (106/300), 36.0% (104/289), and 35.2% (93/264) of patients at weeks 12, 24, and 52, respectively. Endoscopic remission was achieved by 18.5% (15/81), 23.0% (28/122), and 25.7% (35/136) of patients at weeks 12, 24, and 52, respectively. Incidence of serious infections, herpes zoster, and venous thromboembolism were 2.1 [0.9–4.2], 0.5 [0.1–1.9], and 1.1 [0.3–2.7], respectively. Among responders, 44.5% (109/245) lost response during follow-up, which was recaptured in 54.9% (39/71) of patients who re-escalated to 10 mg BID. Patients with a baseline Mayo endoscopic score of 3 (adjusted hazard ratio 3.60 [95% confidence interval: 1.70–7.62]) and prior biologic failure (adjusted hazard ratio 3.89 [95% confidence interval: 1.28–11.86]) were at a higher risk for losing response after dose reduction.

DISCUSSION:

One-third of patients with UC treated with tofacitinib achieved clinical remission with few serious adverse events. However, half of patients lost response with de-escalation, which was only partially recaptured with increasing the maintenance dose. Those with negative prognostic factors should be counselled about the risks and benefits of continuing high doses of tofacitinib.

SSürdürülebilir bir rekabet için dış müşteriler kadar iç müşteri olarak nitelendirilebilecek çalışanların istek, ihtiyaç ve düşüncelerinin dikkate alınması da önemli bir gereklilik olarak karşımıza çıkmaktadır. Bu istek ve ihtiyaçların tatmin edilmesi tıpkı dış müşteri tatminin sağlanması gibi çalışanların da iş tatminini sağlayabilir. Bu düşünceden hareketle mevcut araştırmada iş tatmini üzerinde etkili olabileceği değerlendirilen örgütün etik değerleri ve söz konusu etkide marka imajı algısı aracı değişken olarak incelenmektedir. Bu kapsamda uluslararası düzeyde üretim ve hizmet sağlayan bir mühendislik firmasının 195 çalışanı araştırmanın evrenini oluşturmaktadır. Çevrimiçi anket formları kullanılarak gerçekleştirilen anket çalışmasına 147 çalışan katılmıştır. Elde edilen bulgular örgüt tarafından benimsenen etik değerlerin, çalışanların iş tatmini düzeyleri üzerinde etkili olduğunu ve bu etkide çalışanların marka imajı konusundaki algılarının aracı etkiye sahip olduğunu göstermektedir. Örgütün etik ilkeler ve değerler çerçevesinde hareket etmesi, çalışanların işlerine ve örgütlerine karşı hissettikleri aidiyeti artırmakta ve bununla birlikte çalışmaktan zevk almaları sonucunu doğurabilmektedir. Ayrıca örgütlerin etik ilke ve değerler konusundaki hassasiyetleri arttıkça, marka imajının çalışanların zihninde güç kazandığını ve böylece işlerinden duydukları hazzın arttığını göstermektedir. Örgütlerin, çalışanları etik değerler konusunda zaman zaman bilgilendirmeleri ve gelecek araştırmalarda marka imajının farklı örgütsel değişkenler aracılığıyla çalışanlar üzerindeki etkilerinin gözlenmesi önerilmektedir.
TRACING PEACEFUL SETTLEMENT INITIATIVES IN TURKISH FOREIGN POLICY: COULD THE SIX-WAY PLATFORM BECOME A NEW ASTANA PROCESS?
Authors: ALAGÖZ Bilgehan
Published: December 2022

This article compares and contrasts the Astana Process, which Türkiye, Russia, and Iran devised for Syria, with the Six-Way Platform Initiative, which Türkiye has offered as a solution mechanism to promote peaceful conditions and foster cooperation in the South Caucasus. In this vein, the process tracing method is applied to assess the Six-Way Platform initiative's chances of success. Over the past twenty years, peace proposals for the South Caucasus have been placed on the agenda under various titles but solutions have never been realized. This article makes a case that the regional-global context and the inclusion of relevant actors has a direct impact on the likelihood of success. Given that Türkiye, İran and Russia have demonstrated their ability to cooperate in the Astana process designed for Syria, there is a greater chance that the Six-Way Platform will be feasible in this case. On the contrary, this fact also increases the likelihood that the Six-Way Platform collaboration endeavor could fail. The opposing interests that Türkiye, Russia, and Iran attempt to advance in Syria have at times stalled the Astana Process, which is still ongoing. This dynamic could have negative repercussions for the Six-Way Platform, as this article argues that, what transpires in Syria will have a significant impact on the South Caucasus' politics, which are already on very fragile ground.

Introduction: Aedes aegypti is the main dengue vector in Indonesia. One of the dengue controls is through insecticides use. The plant-based insecticide is one alternative that can be used to minimize the impact of chemical insecticides. Ocimum basilicum is one of the plants that have the potency to be used as insecticides. The aims of this study were to analyze the insecticide activity of Ocimum basilicum essential oil against Aedes aegypti as well as its Lethal Concentration (LC50 and LC90) and Knockdown Time ( KT50 and KT90).Methods: Treatment groups were given Ocimum basilicum essential oil of 100 ppm, 50 ppm, and 25 ppm. The tests were performed four times with 10 mosquitoes per test.Results: The mortality rate of the mosquito on the extract with a concentration of 100 ppm was 100%, 50 ppm was 10% and 25 ppm was 0% and the value of LC50 = 62.9 ppm and LC90 = 78.7 ppm. KT50 of this study was 19.4 minutes and KT90 was 8.07 minutes.Conclusion: Ocimum basilicum essential oil has a mosquitocidal effect on Aedes aegypti. Further studies to investigate the substances of Ocimum basilicum against Aedes aegypti are needed.

Published: December 2022

Introduction: According to the 2018 Basic Health Research (Riskesdas), the highest prevalence of stroke occurs among the elderly group. On the other hand, the proportion of disability among the elderly with stroke was highest compared to the elderly with another disease. Disabled elderly resulted in a high burden of care. This study aimed to analyze the risk factors associated with disability among the elderly with stroke in Indonesia.Methods: This cross-sectional study uses secondary data from Riskesdas 2018. The sample was all elderly aged ≥60 years in Indonesia that participated in the Riskesdas 2018 who diagnosed with stroke by a doctor and met the inclusion criteria (2439 samples). This study employed chi-square and logistic regression.Results: The risk factors associated with disability among the elderly with stroke were older age, having a low education level, living in a rural area, not being obese, having a mental emotional disorder, having no smoking history, and less physical activity. Multivariate analysis showed that less physical activity (PR=18.097; 95%CI=7.306-44.825), low level of education (PR=3.555; 95%CI=1.616-7.823), mental emotional disorders (PR=1.942; 95%CI=1.262-2.988) were the risk factors of disability among elderly with stroke. Being obese (PR= 0.578; 95%CI=0.345-0.970), having a joint disease (PR=0.546; 95%CI=0.311-0.958), and having a smoking history (PR=0.461; 95%CI=0.280-0.759) were the protective factors of disability among elderly with stroke.Conclusion: Physical rehabilitation and mental-emotional disorder treatment have important roles in preventing disability among the elderly with stroke
Panowie i niewolnicy – gospodarka okresu halsztackiego
Authors: Gralak Tomasz
Published: December 2022

During the Hallstatt period in Central Europe, profound cultural, economic, and social changes occurred. This is due to the emergence of new technologies ‒ primarily iron metallurgy. Another element is the vicinity of the dominant economic system, i.e., the broadly understood Mediterranean civi-lization, especially the Etruscan cities in Italy. These asymmetrical relationships forced social changes in the areas north of the Alps. An important factor was probably the slave trade, which forced violence and armed struggle. This resulted in a progressive militarization, which is visible through the construction of defensive settlements and the strengthening of farms. The consequence was extreme social stratification and the domination of aristocratic elites. Thus, the stability of such a system depended on the relationship with the dominant partner. In a situation of disruption of relationships, a crisis must have arisen, resulting in the collapse of this culture model.
Archeological and anthropological approaches to the ontology of the Dewil Valley landscapes (Palawan, Philippines)
Authors: Kowalczyk Zuzanna
Published: December 2022

This paper is a discussion of the theoretical conceptualization of past landscapes and the limitations of archaeology in providing objectivistic interpretations. Analyzing a case study of the Dewil Valley landscape I will argue that the sciences about the past emerged based on the “Western” research paradigm. Therefore, local ontologies are often overlooked in archaeological narratives. In this article, I will present the ontologies of the indigenous Tagbanua people, contemporary beliefs related to the landscape, and theoretical approaches presented by researchers. I will argue that ontology can be complex and ambivalent, and that archaeological sources do not always indicate these dynamics.
Open structure magnetic particle imaging by nonlinear back projection tomography reconstruction
Authors: Zu Wanni , Ke Li , Du Qiang
Published: December 2022

Objectives

In open structure MPI systems, the nonlinear variation of the field free lines in the large region of interest scanning process distorts the x-space image reconstruction. In this study, we propose a nonlinear field free line projection reconstruction algorithm to solve the edge distortion problem of open structure MPI imaging.

Methods

First, we calculate the curvature change law of the field free line in the scanning process. Then, we design a nonlinear back projection reconstruction algorithm according to the nonlinear characteristics of the field free line in the scanning process. Finally, the nonlinear back projection reconstruction algorithm is used to complete the tomography of blood vessels.

Results

The numerical calculation and simulation results show that the open structure MPI combined with a nonlinear back projection reconstruction algorithm can accomplish vascular fault reconstruction. The reconstruction algorithm proposed in this paper suppresses the edge distortion of the image and improves the positioning accuracy of the image. The size of the region of interest where distortions are low is increased 16 times by allowing 10.9% degradation in the gradient.

Conclusions

We provide a non-linear inverse projection reconstruction algorithm to reduce the structural artefacts caused by FFL distortion. It provides a reconstruction scheme for a large region of interest fine imaging of open structure FFL-MPI.
Opposition in ecological discourse: An ecostylistic scrutiny of speakGreen ecological posts
Authors: Virdis Daniela Francesca
Published: December 2022

This article explores the posts with ecological concerns published by the community organization speakGreen on its website and Facebook page. The analysis falls within the aims and scope of ecostylistics, and is undertaken by applying Lesley Jeffries’ stylistic model of opposition. The main research purpose of this article is to identify the stylistic strategies promoting beneficial stories and those controverting destructive stories, in Arran Stibbe’s terminology. A broader research purpose is to assess whether the stylistic model of opposition can fruitfully be utilized to examine ecologically-oriented short texts and the non-literary text type of the speakGreen post. This ecostylistic study firstly demonstrates that unconventional opposites are more effective than conventional opposites in conveying beneficial stories, since their unexpected contrasts surprise the speakGreen website and Facebook users. Secondly, the study proves that two structural triggers of opposition, namely negation and especially parallel structure, are the most frequent in the sample of posts under investigation, due to the stylistic and discursive characteristics of the speakGreen post text type. The sample was also found to feature: (1) The visual trigger of green and red color-coding, which indicates contrast between beneficial stories and destructive stories; (2) Such stylistic devices as foregrounded end-focus and phonological parallelism. All these stylistic traits contribute to making the posts articulate texts relaying refined ecological messages in very few words.

Published: December 2022

Climate change has important implications on human health, affecting almost every system in the body. Multiple studies have raised the possibility of climate change impacting eye health. In this review, we aimed to summarize current literature on the impact of air pollution and climate change on eye health. We performed a search in four different databases, including Medline, Scopus, Cochrane, and Web of Sciences databases. The search strategy combined terms regarding eye health and environmental/climate changes. The outcome of interest included all eye conditions. The search yielded 2,051 unique articles. After applying inclusion and exclusion criteria, 61 articles were included in this systematic review with data covering 2,620,030 participants. Most studies originated from China, India, South Korea, and USA. Climate change adversely affected different eye conditions, with ocular surface diseases (e.g., conjunctivitis and dry eye) being most affected. Moreover, higher particulate matter (PM) was the most widely assessed pollutant and was adversely associated with the majority of eye conditions, increasing the burden on patients and healthcare providers. We found a low frequency of publications related to the delivery of eye care and its impact on climate change in countries with high air pollution and climate change burden.
An assemblage of the 17th to 18th century coins found during archaeological investigation of the Kupiškis central square
Authors: Remecas Eduardas , Simniškytė Andra
Published: December 2022

In 2018, during reconstruction works at the central square of the town of Kupiškis and the subsequent archaeological investigation, 153 coins dating to the 17th to 20th centuries were found. Usually only coins of the lowest denomination and value are found during such investigations, but most of the coins found at the central square in Kupiškis were attributable to the medium denomination coin type. It has been established that the majority of the 17th-century coins (125 pieces) belonged to a coin assemblage or hoard which was scattered before the reconstruction of the square. Based on the historical and numismatic data, it has been assumed that this set of coins was hidden around 1709 to 1710, when the country was devastated by the plague, and that it would likely have belonged to a keeper of a shop that used to stand at the market square. The composition of the said collection of coins was typical of the monetary circulation of that period, with some unique features as well. Compared to other finds, the assemblage contained a larger number of lower medium denomination coins and considerably fewer higher denomination coins. This suggests that the owner of the money was engaged in retail trade. The assemblage is also characterised by a larger number and diversity of Swedish coins. This unique feature can be explained by the fact that in the 17th and 18th centuries the region of Kupiškis was famous for flax cultivation and trade.
Paskutinio Lietuvos Didžiosios Kunigaikštystės didžiojo maršalo Liudviko Skumino Tiškevičiaus sveikata, mityba ir mirtis | The Health, Nutrition and Death of Ludwik Skumin Tyszkiewicz, the Last Grand Marshal of the Grand Duchy of Lithuania

Published: December 2022

Many changes took place in the upper echelons of Lithuanian society at the turn of the 18th and 19th centuries: a divide began to emerge between the conservative aristocracy and the supporters of Enlightenment ideas. The latter sought reforms, the independence of the state and progress in society. The former did not support the changes, and sought to preserve the former structure of society, often seeking the support of politicians in the Russian Empire. It is important to study not only the actions of the elite of that period in the field of politics, but also their households and lifestyles. The paper explains what can be learnt about factors that may have influenced the health of Ludwik Skumin Tyszkiewicz (1751–1808), one of the most prominent Lithuanian political figures at the turn of the 18th and 19th centuries. The main character in the article is regarded in historiography as a noble with conservative views, who focused on the accumulation of material goods. The paper investigates what is known about the health problems of the count. It also explains what products were used in his kitchen, and what the stresses were in his life that could have affected his health. The circumstances of his death and funeral are also mentioned.

From the earliest descriptions and studies, the Prussian Lithuanians, or Lietuvininkai, and their sung folklore have usually been treated as one unit. However, the ethnographic region of Lithuania Minor is a vast territory stretching over 200 kilometres from north to south. Two distinct areas of ethnic Lietuvininkai music can be identified within it. This article aims to investigate the musical features of the folklore that existed in the Klaipėda district, and to reveal its uniqueness in the context of Lietuvininkai sung folklore.

Background. Whey, a waste product from cheese production, is an underutilized raw material with high nutritional value. This waste product may be used in the production of fermented beverages. The aim of this study was to develop an innovative fermented beverage based on whey and fruit vinegar and to determine the survivability of two probiotic strains of lactic acid bacteria. The study included the preparation of individual components, the selection of their appropriate proportions and the verification of the influence of storage conditions and time on the survivability of the strains. The biological material consisted of Saccharomyces cerevisiae wine yeast strain, Acetobacter pasterianus O4 and Acetobacter pasterianus MW3 acetic bacteria strains and lactic acid bacteria strains: Lacticaseibacillus rhamnosus GG ATCC 53103 and Lactiplantibacillus plantarum LMG P-21021. The survivabilityl of lactic acid bacteria was tested under anaerobic conditions. The beverage was made of whey mixed with 10 % to 50 % apple cider vinegar. The above beverage was kept at a temperature of 21 ± 2 °C and 3 ± 2 °C for 21 days. Results and conclusion. The beverage was analyzed once a week, and the number of lactic acid bacteria after 21 days of storage was at a high level, exceeding the WHO recommended number of bacteria in probiotic beverages – 106 ÷ 107 CFU/cm3 . The beverage based on whey and the addition of 10 % vinegar was a good medium, and the number of lactic acid bacteria in each variant of the beverage was on average 8.4 ± 0.29 log CFU/cm3 .

Optical spectra of the doped Bi2Te3 show that absorption lies in visible and near UV region of the radiation. Thus, it seems to have potential applications in optoelectronics. Thermoelectric properties favor the semiconducting nature with high Seebeck coefficient and dominant character of p-type charge carriers.

The influence of γ-quanta on the current flow in TlInSe2 single crystals and the process of filling and emptying localized levels in crystals has been experimentally studied. Investigations show that the current -voltage characteristics (CVC) of TlInSe2 single crystals obey Lampert theory and are determined by currents limited by the space charge. It is shown that the defects occurring from γ-quanta in TlInSe2 single crystals result from radiation processes

Titanium butoxide (Ti(OBu)4) precursor was used to prepare titanium dioxide (TiO2) nanorods as a photoanode by hydrothermal method directly on FTO glass with different hydrochloric acid (HCl) – water (H2O) ratio (12.5-7.5, 10-10, 7.5-12.5 and 5-15) ml and etching times (24, 48, and 72)h. The (XRD) results show good crystallinity of TiO2 with rutile phase and preferred orientations (101) and (002) for all samples. The grain size of the TiO2 nanorods increases with decrease the HCl concentration. The (FESEM) images show that an increase in HCl concentration leads to an increase in the rod diameter of the TiO2 NRs and a decrease in their length. The optimum efficiency (η) of DSSC based on TiO2 NRs was 3.255% at sample ET, where the preparation condition (7.5 ml HCl + 12.5 H2O) with a 48 h etching time.

The present investigation depicts the removal of Safranine-Bdye from aqueous solution using senegalia Catechu activated carbon incorporated Ba-alginate composite beads. The alginate beads were synthesized by metal encapsulation technique using BaSO4 as an encapsulating agent. The Safranine-B dye removal efficiency was determinedby the modeling equations like Langmuir and Freundlich. The nature of physical, chemical force of attractionbetween the adsorbate vs. adsorbent and feasibility was determined using pseudo order equations of first andsecond. The progressiveness of the interaction process was predicted by intraparticle diffusion, enthalpy, entropy and Gibbs free energy model equations. Experimentally obtainedoutcomes were implied that the adsorption of Safranine-Bwas feasible for all the parameters used in this study. Furthermore, the predicted diffusion valueswere revealedthat the contact between Safranine-B versus composite beads was well diffused. The surface morphology of virgin and Safranine-B loaded images confirms that the Safranine-B was strappinglybind on outerlayer of the composite. The results of the FTIR spectrum indicatethe Safranine-Bwas intensively attached on thecomposite surface. The TGA result revealsthat the Ba composite bead has predominant temperature bearing nature.

γ-PGA-PAE nanomaterials were prepared by spontaneous assembly of γ-PGA through condensation reaction, and preparation process of nanomaterials was optimized. HCPT/PGA-PAE nanospheres were prepared by using 10-hydroxycamptothecin as embedding drug, and the nanospheres prepared under the optimal conditions were characterized. The results showed that γ-PGA-PAE nanomaterials were successfully prepared with spherical shape and uniform distribution. HCPT/PGA-PAE nanospheres had high encapsulation rate and drug loading. The optimization of the processing conditions of nanomaterials by response surface method (RSM) is a feasible method to improve the utilization rate of γ-PGA, which provides a theoretical basis for the synthesis of nanomaterials in the future

Ferroelectric BaZr1-xTixO3 (0 ≤ x ≤ 8) ceramic composition was synthesized by using solid state reaction method. The material was calcined at 1250 °C in air. In this work we have examined that the ferroelectric, energy storage and microwave dielectric properties of BaZr1-xTixO3 at room temperature. The XRD patterns showed that BaZr1-xTixO3 composition is of perovskite structure with a space group of Pm-3m. SEM morphology shows that increase in number of grain boundaries result in increase of polarisation. The energy storage properties were calculated from (P-E) loops by varying the electric field (range) and composition of the ceramic material. It has observed that the relative permittivity increases along with temperature. The storage energy density (Wrec) has been reported 0.043 J/cm3 , whereas efficiency (ɳ) was 57% at room temperature and 40 kv/cm at contents (x=0.06).The Barium zirconium titanate (BZT) will be an excellent candidate material for storage energy devices.

In this paper we prepared glasses with composition (75-x)TeO2–5Nb2O5–20ZnO–xNa2O mol%, (x = 7, 10, 15, and 18) were synthesized by using the conventional quench-melting method. The Faraday effect has been investigated as well as the structure of these glasses was analyzed by Raman spectroscopy. It can observe that when the Na2O concentration increased from 7 to 18 mol%, the value of the Verdet constant decreased from 0.113 to 0.071 min/G.cm. This result can be interpreted as the following: when adding Na2O into the glass matrix, leads to the attendance of non-bridging oxygens (NBO). The peak (d) in the range of 717–721 cm−1 is related to the stretching vibrations of Te˗O˗ and Te=O bonds containing nonbridging oxygen in TeO3 (tp) phase.
