Authors: Volkova Аnastasiia D. , Ivanova Natalia L. , Patosha Оlga I.
Published: February 2022

Background. With the growing role of economic environment in the socialization of a modern person, there is an increasing interest in understanding the socio-psychological mechanisms of human behavior when choosing goods. Economic realms are refl ected in the self-identifi cation of the individual in relation to other people and social structures. Th e study of the relationship between social identity and the features of consumer behavior when choosing goods is relevant. At the same time, various aspects of social identity in connection with the peculiarities of consumer preferences remain poorly studied in social psychology. Objective. Th e study is aimed at identifying the relationship between the components of social identity and the characteristics of consumer preferences (using the example of locally produced food). Design. Th e study was conducted online by presenting respondents with a questionnaire that included questions about consumer preferences and components of social identity. Th e sample was targeted by experts: consumers of food products of local production, citizens of the Russian Federation, aged 25 to 67 years (N = 200). Results. Th e interrelation of cognitive and value components of social identity with the peculiarities of consumer preferences concerning general attitude to products, their characteristics and selection criteria is revealed. More significant connections were found between value components and all manifestations of consumer preferences. Th e interrelation between local and world identity and preference for food products of domestic production, as well as the features of the criteria for choosing food products among consumers with diff erent severity of the cognitive component of social identity, has been revealed. Conclusion. New data on the relationship between cognitive and value components of social identity and the characteristics of consumer preferences were obtained. Th ey can serve as a basis for a deeper analysis of the identity structure, understanding the role of identity in consumer behavior. Th e main limitations of the study relate to the sample and the methods used.

Published: February 2022

Abstract. Fly-in-fl y-out personnel in the Far North are exposed to extreme climatic, geographic, and production factors, and also remain in conditions of group isolation, which makes demands on fl y-in-fl y-out worker’ body that oft en exceed its reserves. Th e full adaptation impossibility is associated with unfavorable functional states of workers, which lead to a decrease in the level of mental health, productivity and work effi ciency. Job tasks of workers in various industries diff er in physical and physiological stress and in the degree of harmful production factors expression. Th e purpose of this study is to identify and describe the psychological adaptation features in fl y-in-fl y-out personnel in industrial enterprises of the Far North. Th e study involved 145 fl y-in-fl y-out workers of oil, gas, and diamond mining industries in the Far North, 82 fl y-in-fl y-out builders in the south of the Russian Federation, who were a comparison group to identify the psychological adaptation features of fl y-in-fl y-out personnel in the Far North. Research methods are psychophysiological and psychological testing aimed at diagnosing conscious self-regulation of voluntary human activity and subjective control as key characteristics of psychological adaptation of workers. Th e results obtained allow us to conclude about the similarity of psychological characteristics that contribute to the successful adaptation of fl yin-fl y-out personnel, regardless of the region where the industrial facility is located. Th ese include internality in the areas of achievement, failure, family relationships, health and illness, as well as modeling, performance evaluation, and autonomy as regulatory processes. At the same time, their expression is specifi c, depending on the region of the object location and the industry.
The Dynamics of the Interrelationships between Conscious Self-regulation, Psychological Well-being and School-related Subjective Well-being in Adolescents: A Three-year Cross-lagged Panel Study
Authors: Morosanova Varvara I. , Fomina Tatiana G. , Bondarenko Irina N.
Published: February 2022

Background. Recently, research on psychological well-being and its dynamics and predictors in adolescence, has gained special attention, due to the importance of well-being for mental and physical health, as well as for success in different activities. Self-regulation (SR) is considered a significant resource for maintaining psychological and school-related subjective well-being. Objective. The purpose of our study was to identify the role of conscious SR in maintaining pupils’ satisfaction with school life, and to assess the contribution of conscious SR to the development of psychological well-being in adolescence. Design. Two three-year longitudinal studies were carried out on samples of young adolescents in Russian schools (N=148; N=132; 10–13 years). The studies utilized methods for assessing conscious SR, psychological well-being (PWB), and school-related subjective well-being (SWB), the latter being the cognitive component of life satisfaction. Results. Our research revealed differences in the dynamics of PWB and SWB levels in adolescents during their transition from primary to basic secondary school. It also identified the specifics of longitudinal relationships between conscious SR, PWB, and SWB in adolescence. We showed that there was a reciprocal relationship between them. However, the most significant cross-longitudinal effects were established between SR and school-related SWB. These effects changed over time: at the beginning, well-being acted as a significant factor of self-regulation, while later self-regulation acted as a significant resource for maintaining adolescent well-being in the subsequent years. Conclusion. School-related SWB is characterized by the most pronounced trajectory of change, while PWB is characterized by greater stability and insignificant growth. Our three-year longitudinal study demonstrated that the link between selfregulation and well-being is consistently reproduced. Conscious self-regulation is a significant resource for both the psychological and school subjective well-being of adolescents.

Background. The study of aspects related to positive mental health and well-being in the general population with a gender approach is a necessity in the current context imposed by COVID-19. Objective. To explore gender as a predictor of subjective well-being during COVID-19 in a sample of the Cuban population. Design. A cross-sectional web-based survey design was adopted. The sample consisted of 129 Cuban participants. The Subjective Well-being-Reduced Scale (SW-RS) was used to explore subjective well-being in the sample. Descriptive statistics were used to explore the participants’ characteristics. A multinomial logistic regression analysis was conducted to identify variables independently associated with the participants’ subjective well-being. Results. The gender of participants significantly predicted subjective well-being levels. The probability of males having middle or high levels of subjective well-being, rather than low levels, was 4.16 times greater than in females. The probability of males having a high self-image instead of a low one was 4.35 times greater than in females. According to the self-satisfaction dimension, the odds of males having high rather than low self-satisfaction were five times more than in females. In this sample, gender did not predict whether participants had middle or high levels of the hedonic dimension.
Measuring TechnoWellness and Its Relationship to Subjective Well-Being: the Mediating Role of Optimism
Authors: Candel Octav S.
Published: February 2022

Background. The relationship between technology use and subjective well-being is controversial, with recent research suggesting both positive and negative links. Thus, it is important to determine whether using technology actually leads to flourishing and well-being. To do so, the construct of TechnoWellness, which includes both adaptive and maladaptive modes of using technology, could be particularly useful. Moreover, the mechanisms that account for these relationships have been insufficiently explored. Objective: With this study, we had two objectives. First, we aimed to test the relationships between TechnoWellness and the three components of subjective well-being (positive affect, negative affect, and satisfaction with life). Secondly, we aimed to investigate whether optimism mediates those relationships. Design: A total of 366 participants (122 men and 244 women, mean age=22.34 years old) took part in this study. In this cross-sectional investigation, we measured TechnoWellness, optimism, positive and negative affect, satisfaction with life, and some demographic variables, using an online form. To verify our aims we used structural equation modeling (SEM) with mediation. Results: Among the positive factors of TechnoWellness, only using technology for physical activity was directly associated with satisfaction with life. Among the negative factors, the stress caused by technology use was directly associated with negative affect. Optimism mediated the relationships between these two factors (using technology for physical activity and stress caused by technology use) and all the components of subjective well-being. Conclusion: Using technology to foster wellness is related to actual subjective well-being. However, the purpose, frequency, and type of its use are important elements to be considered when studying its effects.
Subjective Appraisal and Orientations in Difficult Life Situations as Predictors of Coping Strategies
Authors: Bityutskaya Ekaterina V. , Korneev Aleksey A.
Published: February 2022

Background. Many studies have shown that problem-focused coping and a positive reappraisal of one’s situation are the most conducive to achieving life goals and psychological well-being, whereas avoidance coping and self-blame have a negative impact on well-being. But there is not enough data on what the predictors of these coping strategies are in the situational context. Objective. To assess the combined influence of subjective appraisal (uncontrollability, unclearness, negative emotions) and orientations in difficult situations (by drive and rejection) on planful problem solving, positive reappraisal, wishful thinking (fantasizing), and self-blame. Design. The research has a survey design. The sample consisted of 637 adult participants who analyzed difficult situations in their lives associated with achieving significant life goals of various types (N=637; 60% female; Mage=24.2; SD=6.25). Two alternative structural models were assessed, which include subjective appraisals of the situation (uncontrollability, unclearness, intensity of negative emotions), orientations in difficult situations (drive and rejection), and ways of coping (planful problem-solving, positive reappraisal, wishful thinking, and self-blame). Results. The first model, in which all cognitive appraisals and orientations in difficult situations directly influence coping strategies, has relatively low fit indices. The second model, in which the influence of cognitive appraisal was partially mediated by orientations in difficult situations, has better fit indices. In life situations involving solution of a difficult task, the strongest predictor of problem-focused coping and positive reappraisal is the “drive” orientation of being attracted to difficulties, which mediates the influence of subjective control and emotions on these ways of coping. An orientation away from difficulties, “rejection,” mediates the influence of unclearness and negative emotions on fantasizing and self-blame. A low level of subjective control directly affects self-blame and the avoidance of problem-solving. Negative emotions are a weak predictor of self-blame. Conclusion. Interaction between the subject and the situation involves appraisal of difficulty, which influences orientation in difficult situations. In turn, orientations are predictors of coping strategies. The characteristics of the psychological situation determine coping, which may be oriented toward approach to or avoidance of the goal.
Athena’s Vote: Imperial Proceedings and the Hegemonic Origins of International Criminal Law in Aeschylus’ Eumenides
Authors: Buis Emiliano J.
Published: February 2022

In this paper, the author gives an account of the final trial scene in Aeschylus’ Eumenides, which in his opinion could be described as a subtle literary representation of the imperial justification of the exercise of criminal legal power over foreigners in classical Athens. Based on a philosophical exploration of the importance of criminal pollution and the need to create a new tribunal—the Areopagus—to institutionally overcome its dreadful consequences, it is contended that Aeschylean drama provides us with an aesthetic justification in antiquity for the creation (and imposition) of courts concerned with international offences which were considered to be extremely serious and dangerous for Athenian interests.

Published: February 2022

On the basis of expansive molecular phylogenetic analyses of the genus Miliusa (Annonaceae) utilising up to seven plastid DNA regions, four major clades are identified: clades A, B, C and D. Members of clade C possess axillary inflorescences and crescent-shaped to semicircular glandular structures at the base or (slightly) higher inside the inner petals. In this clade, accessions of M. mollis are recovered as a monophyletic group, divided into two major clades. One of them is recognised as a new species, M. microphylla, which differs from the other (M. mollis) in the following characters: pedicel length, as well as glandular structures and indumentum on the inner petals. The new species is endemic to southeastern Thailand, whereas M. mollis has a much wider distribution (central, eastern, northeastern, northern and peninsular Thailand plus Cambodia and Vietnam). In addition, M. glandulifera, a new record for Thailand, is retrieved as the sister group of a clade composed of M. microphylla and M. mollis. The name M. glandulifera is lectotypified and the description of M. glandulifera is emended, with the information on mature monocarps added. The conservation status of M. microphylla and M. glandulifera is provisionally assessed. A revised key to the species in clade C in Thailand is provided. The phylogenetic position of M. nakhonsiana and M. sessilis in clade C, as well as of M. chantaburiana and M. eupoda in clade B is confirmed for the first time.

Authors: Han Duksun , Kim Yonghyun , Kim Young-Woo , Park Jong-Bae , Kim Dae Chul , Kim Jongsik
Published: February 2022

Aluminum-doped zinc oxide (AZO) thin films were prepared on a glass substrate by employing a toroidal magnetron sputtering system to enhance both resistivity and transparency. The glass substrate temperature was sustained below 50 °C during the deposition of 200 nm thick AZO without
an additional heating system for the substrate, and no pre- or postannealing process was carried out. This scenario is quite desirable to reduce damage to the thermally sensitive substrate during the conventional AZO thin film process; nonetheless, significant crystallinity was observed in
the XRD analysis due to energy transfer by sputtered ions. The electrical resistivity was approximately 8.3×10−4 Ωcm, and the average transmittance was 90.43%, which were achieved under optimized conditions, with the ratio between the O2 and Ar gas flow
rates varied under a specific applied DC power.

Published: February 2022

BIPV modules have many advantages, but they are expensive to install, so it is important to increase the persistence of BIPV modules. To increase the durability of the BIPV module, one of the key components, the encapsulant, was changed to extend the life of the BIPV module and measure
the efficiency. Because the core elements of the BIPV module and the PV module are the same, the output before and after deterioration of the PV module made of each encapsulant was compared.

Authors: Yang Han , Wu Xia , Lei Jing , Li Huan
Published: February 2022

Differential expression of miR-223 is related to the progression of tuberculosis. This study mainly explored the effect of albumin nanoparticles carrying miR-223 on macrophage autophagy in tuberculosis and related mechanisms. Sixty SD rats were selected and randomly divided into (n
= 10 for each, 12 mg/mL) sham group, model group, miR-223 group, isoniazid group, STAT3 pathway inhibitor group, and STAT3 pathway agonist group. The rat body weight and number of Mycobacterium tuberculosis were measured and expressions of miR-223, p-STAT3, STAT3, Beclin1, and LC3-II/LC3-I
were determined. Moreover, the targeting relationship between miR-223 and STAT3 was analyzed. The difference in the rat weight between four groups was not significance in the 1st day (P > 0.05), while the weight of the model group was lowest on the 15th day, and weights of the other
three groups increased significantly (P < 0.05). The number of Mycobacterium tuberculosis in the model group reached (8.58±0.22) lg10, while the number of Mycobacterium tuberculosis in the isoniazid group and miR-223 group were lower than the model group (P
< 0.05). The expression of miR-223 in the model group was lower than in the other groups (P < 0.05). The expressions of p-STAT3 and STAT3 were highest but the expressions of Beclin1 and LC3-II/LC3-I were lowest in the model group (P < 0.05). The expressions of p-STAT3
and STAT3 were highest in the model and STAT3 pathway agonist groups, while expressions of Beclin1 and LC3-II/LC3-I, and the number of Mycobacterium tuberculosis were lowest, while the sham and STAT3 pathway inhibitor groups showed opposite trends (P < 0.05). Moreover, significant
difference was found in comparisons between model group and STAT3 pathway agonist group (P < 0.05), but no such significance existed between the sham and STAT3 pathway inhibitor groups (P > 0.05). In conclusion, albumin nanoparticles-encapsulated miR-223 slowed release
of miR-223 to the body, which directly inhibited the activity of STAT3 pathway and downregulated the expression of STAT3 and p-STAT3, but up-regulated the expression of Beclin1 and LC3-II/LC3-I expression, ultimately promoting macrophage autophagy in tuberculosis. The main mechanism for miR-223
was related to inhibition of the STAT3 pathway.

Prostate cancer (PC) is the most frequently diagnosed cancer in men and it is difficult to achieve the desired therapeutic effect through traditional chemotherapy. Thus, it is necessary to develop advanced strategies to treat PC. Functionalized nanoparticles have been developed as a
unique tumor-targeted delivery platform for PC therapy. In this study, tumor-targeted RGD-silver nanoparticles (RGD-Ag NPs) were prepared, in which RGD could specially bind with its receptor αvβ3 integrin over-expressed on LNCaP cells. RGD-Ag NPs were adopted to load
adriamycin (Am) to prepare functionalized silver nanoparticles (RGD-Ag@Am). The average particle size of RGD-Ag@Am was about 65 nm and kept under 90 nm during the 8-day trial period. LNCaP cells showed greater uptake in RGD-Ag@Am group compared to Ag@Am group, indicating active targeting of
carrier RGD-Ag NPs could effectively enhance the uptake of Am in LNCaP cells. RGD-Ag@Am entered LNCaP cells in a clathrin-mediated energy-dependent manner and demonstrated an excellent pH-response release of Am under the acidic condition, which was conducive to enhancing the distribution of
Am in the tumor microenvironment. RGD-Ag@Am inhibited the proliferation and invasion of LNCaP cells and induced LNCaP cell apoptosis which probably promotes the production of reactive oxygen species (ROS). It was noteworthy that RGD-Ag@Am exhibited greater anti-cancer activity in comparison
with free Am and Ag@Am in the LNCaP cell model, indicating that RGD-Ag NPs had the ability to enhance the anti-cancer efficacy of Am. These findings showed that RGD-Ag@Am has promising potential for use in PC therapy.

Authors: Guo Kai , Tong Zhou , Pan Wen-Hao , Liu Lin
Published: February 2022

Rapid carbonation test of recycled concrete specimens with graphene oxide (GO) contents of 0, 0.03, 0.06, and 0.09% are carried out. The hydration products, micropore distribution, and micromorphology of recycled concrete specimens are characterized by performing thermogravimetric analysis,
X-Ray Diffraction (XRD), a mercury intrusion test, and scanning electron microscopy (SEM). The results show that the carbonization resistance of recycled concrete specimens mixed with GO has been improved to varying degrees compared with that of ordinary recycled concrete specimens. When the
GO content was 0.06%, the improvement effect was the best. This improvement is attributed to the improvement of the microstructure and pore characteristics of recycled concrete owing to the presence of GO. In the microstructure of recycled concrete specimens with GO, the shape of hydrated
crystals is more regular and the section is more compact. In microscopic pores, the ratio of harmful pores and multiple harmful pores is effectively controlled. In this work, the multiscale characterization of the test specimens from the micro to mesolevel is realized by combining various
technical approaches. The influences of different GO contents on the carbonization resistance of recycled concrete are proven, and the mechanism responsible for improving the carbonization resistance of recycled concrete is explored.

Published: February 2022

Aluminium foam has been popular in engineering, and aluminium foam research has become a research hotspot. The strain–stress relationship of aluminium foam presents three distinct stages. In this paper, the mechanical behaviours of aluminium foam materials under dynamic and quasi-static
compression are studied. The effects of density, strain rate and temperature on the dynamic mechanical behavior of aluminum foam were analyzed. Combined with the dynamic and static stress–strain curves of aluminium foam, the specific characteristics and the phenomena in every stage of
the compression process were studied by high-speed photography and CT. The experimental results show that aluminium foam undergoes obvious collapse layerby-layer in the process of compression. The stress–strain curves include a considerable stress drop after the elastic stage. Moreover,
the structural defects of the material will cause the plastic failure in advance, and the possibility of the existence of structural defects will be affected by the density. Under dynamic compression, with increasing density the strain rate sensitivity of aluminium foam increase, but with
the temperature increasing, the strain rate sensitivity was decrease.

This study was to analyze the application of liquid Perfluorohexane (PFH) nanoparticles (NPs) combined with ultrasound image in the diagnosis of the location of the fetal medullary cone (MC). The rotary evaporationultrasound (REUS) method was adopted to prepare the targeted phase-shift
liquid PFH NPs carrying 10-Hydroxy camptothecin (HCPT) (TPS-HCPT-PFH-NPs), which were applied in ultrasound detection to locate the MC of 126 fetuses. The results showed that under 4 °C, TPS-HCPT-PFH-NPs showed a slow upward trend with time, but the increase was not significant; the particle
size of TPS-HCPT-PFH-NPs showed an obvious increasing trend at the 0th–40th hour, and the growth rate was slow after the 40th hour. Its final drug release rate (DRR) reached 78.22%. Fetal MC distributed in vertebral body L2–L3 in the most cases (51 cases), followed by vertebral
body L2 (32 cases), L3 (23 cases), and L1–L2 (17 cases). The number of caudal vertebral bodies in fetuses >35 weeks was obviously more than that of fetuses at 20–25 weeks and 25–35 weeks (P < 0.05). The MC position of fetuses at >35 weeks was observable greater
than that of fetuses at 20–25 weeks and 25– 35 weeks (P < 0.05). The contrast-enhanced ultrasound based on TPS-HCPT-PFH-NPs showed visibly higher diagnostic accuracy and shorter running time in contrast to the routine ultrasound (P < 0.05). In short, the TPSHCPT-PFH-NPs
showed good stability, thermal phase-shift, and DRR. Thus, it could effectively improve the diagnostic effect of ultrasound, and could be promoted in clinic. The location of fetal MC was mainly distributed in vertebra L2–L3, which showed a reliable linear correlation with gestational
age.

This work aimed to study the experiment of Mycobacterium tuberculosis (MTB) detection via magnetic nanoparticle (MNP) capture combined with polymerase chain reaction (PCR) technology. Thirty sputum samples were collected, MTB was isolated and cultured, and DNA templates were prepared.
Fe3O4-polyethylene imide (PEI) MNPs were prepared, and PCR was adopted to test the 30 samples. Within the range of 0–600 °C, as the temperature rose, the quality of Fe3O4-PEI MNPs was gradually reduced. MNPs were positively charged when the pH value was 2–8.
The highest capture rate of MTB with OD500 = 0.4 was 71%. The highest capture rate of MTB with OD500 = 0.6 was 58%. The highest capture rate of MTB with OD500 = 0.8 was 26%. When the temperature was heated to 900 ˚C, the thermal weight loss of MTB was
about 85% if MNP wasn’t added. The thermal weight loss of MNP-captured MTB was about 45%, while that of uncaptured MTB was about 71%. In summary, polyethyleneimine could enhance the adsorption of MNP to MTB, and the capture rate gradually increased over time. The lipid of the cell wall
of MTB was involved in the interaction between MTB and MNP.

This study was intended to explore the effects of Chlorhexidine di(acetate)-Na-Monotmorillonite (CA-MMT) nanoparticles on implantable venous access port (PORT) nursing of hematopathy patients, which was expected to provide a more effective alternative for PORT nursing and alleviate
the suffering of hematopathy patients. CA-MMT nanoparticles were prepared and characterized by X-ray and infrared spectroscopy. Specifically, CA and Na-MMT were dissolved in double distilled water, and then added to a round-bottomed flask and mixed uniformly. After the mixture was condensed
and refluxed, the product in the flask was filtered, and then washed with double distilled water for several times, followed by suction filtration. The obtained off-white block solid was dried at high temperature, and then ground and sieved to obtain CA-MMT nanoparticles. 64 hematopathy patients
were selected as research subjects and were randomly divided into control group and nano group. After the PORT surgery, the nano group had CA-MMT nursing, with the control group having iodophor nursing. The routine blood indexes and the phlebitis incidence were compared between the two groups
for analysis. The results showed that the CA was successfully intercalated between layers of MMT, which had a relatively good dispersion property with a regular shape. Before the puncture, the two groups showed no notable differences (P > 0.05), while after the needle was removed,
a notable difference was noted (P < 0.05). The phlebitis probability in the control and the nano group was 37.5% and 15.6%, respectively, indicating a notable difference (P < 0.05). In conclusion, the CA is successfully intercalated between MMT layers. The CA-MMT nanoparticle
is instrumental in reducing the incidence of infections and phlebitis, demonstrating good effects on PORT nursing of hematopathy patients.

Authors: Gonzalez Kirsten A. , Pulice-Farrow Lex , Abreu Roberto L.
Published: February 2022

The present study explored strategies that LGBTQ people used to cope during the U.S. presidential administration of Donald Trump. Coping strategies can buffer the impact of identity-related stigma and decreased psychological well-being, however, little is known about the ongoing coping strategies used by LGBTQ people during Trump’s presidential administration. This research addresses this gap in the literature. Participants included 335 LGBTQ individuals who were negatively impacted by the discriminatory policies of the Trump administration. Participants completed an online survey where they discussed the coping strategies they used during the Trump administration. Thematic analysis revealed five coping-related themes, including: (a) Coping Through Connecting With People, (b) Coping Through Self-Care and Self-Preservation Activities, (c) Coping Through Relational Disengagement, (d) Coping Through Activism, and (e) Coping Through Outness Decisions. Our discussion explores how counseling psychologists can work with LGBTQ clients to maximize coping strategies for managing distress during anti-LGBTQ presidential administrations.

Published: February 2022

In acute stroke, neuroinflammation can nowadays be analyzed by local cerebral aspiration of pial-ischemic blood during mechanical thrombectomy. Recently, Shaw et al. reported on differences in leukocyte subpopulations within the occluded cerebrovascular compartment. In their study, a main proportion of granulocytes was lost during isolation. By immediate analysis, we found a reproducible increase in absolute local granulocytes without variations in absolute lymphocyte and monocyte numbers. Flow-cytometric phenotyping confirmed a high proportion of granulocytes and a local shift towards CD4+ T cells. Thus, immediate analysis appears to be critical to observe distinct local responses of leukocytes to acute ischemic stroke.

The combination of desirable polymer properties and methods for synthesis, utilizing materials with various architectures, could be adopted for diverse clinical applications such as wound healing as well as stem cell differentiation. Natural polymers, particularly polysaccharides, are biocompatible and are reported to have structural similarities with extracellular matrix components. In this scenario, the present study fabricated a porous scaffold using a polysaccharide, galactoxyloglucan, isolated from Tamarind seed kernel, and studied its applications in stem cell attachment and wound healing. In-growth of human mesenchymal stem cells (hMSCs) presented a rounded morphology with increased proliferation. Scaffolds were surface-functionalized with silver nanoparticles to increase the antibacterial activity and the wound healing potential evaluated in preclinical mouse models.

Neuroprosthetics, with a range of applications such as cognitive, auditory, pain relief, recording, motor, and visual prosthetics have emerged as a promising field in recent years. However, poor electrical conductivity, a high disparity between tissue and interfaces and the onset of reactive gliosis post-implantation remains major challenges in the development of neuroprostheses. The choice of biomaterials in designing the neural interfaces’ in neuroprosthetic applications is of high importance, as the overall sustained performance of neuroprosthetic devices is based on the features of materials used for the neural interfaces. Numerous biomaterials, such as metals and carbon-based materials, have been used in neuroprosthetics thus far. Nonetheless, neuroprosthetics made from polymeric biomaterials are in high demand due to their high biocompatibility, conductivity, and biostability. Furthermore, polymeric biomaterials can be used as a hybrid design to overcome the limitations of other co-biomaterials. This article makes an attempt to review the polymeric biomaterials involved in this cutting-edge technology utilized for different purposes such as substrates, coatings, and miniaturization of electrodes, that might help in enriching our understanding on neuroprosthetics.

Published: February 2022

Objective

The Victorian Voluntary Assisted Dying Act 2017 (the Act) exposed a spectrum of opinions regarding euthanasia and physician-assisted suicide amongst Victorian palliative care physicians leading to sometimes acrimonious debate. The profession was unable to articulate a unified role in respect of VAD.

Method

A collaboration between psychiatry and palliative care led to a series of group discussions in order to prepare for the Act and to re-establish professional cohesion.

Results

Although the meetings revealed a plurality of views regarding VAD amongst palliative care physicians, the majority were firmly against the Act. Early meetings revealed strong feelings of shock and an inability to proceed. Previous debates resurfaced between those in support and those not in support of VAD. Over time, there was increased acceptance of the need to adapt to the presence of the Act in order to limit its impact on the robust relationship with the patient central to the practice of palliative care.

Conclusions

The implementation of VAD legislation requires an active process to address the challenges it represents for palliative care physicians. Collaborative facilitated meetings can help re-establish group cohesion through affirming the core principles of palliative care which remain independent of VAD
Successful Treatment of a 92-Year-Old Classic Kaposi's Sarcoma Man With Ultra-Low Dose Oral Etoposide
Authors: Tas Faruk , Sakar Burak
Published: February 2022

Introduction

Because classic Kaposi's sarcoma (CKS) is currently regarded as a low-grade vascular malignancy, it has been usually known as indolent clinical course. The slow-growing neoplasms are usually asymptomatic and rarely systematically progressive. Although CKS is a chronic disease which is rarely life-threatening, systemic therapy may be necessary in some patients with symptomatic skin or visceral involvement.

Case report

In this report, we presented a 92-year-old CKS man with widespread and symptomatic skin lesions.

Management and outcome

Patient was treated successfully with ultra-low dose oral etoposide; 50 mg/day for 7 days. Cycles were repeated in every 21 days. There was a dramatic regression in all lesions at the end of treatment; only skin colorations were persisted instead of palpable nodular lesions. Moreover, no serious hematological and non-hematological adverse events were observed.

Discussion

Fragile advanced CKS patients with advanced age and/or comorbitidies need to be considered to optimize outcomes. Treatment with single-agent oral chemotherapy, oral ultra-low dose etoposide, may be one of the effective treatment styles.

Taeniasis is an intestinal helminth infection due to adult tapeworms belonging to the genus Taenia. Taeniasis remains a major burden in low-income countries in Asia. We present a case of intestinal perforation caused by adult tapeworm of Taenia in a 50-year-old Nepali male. The patients presented to the hospital with severe abdominal pain and intermittent vomiting. Following clinical presentations and imaging features, gastrointestinal perforation was suspected. Surgical removal of adult tapeworm of Taenia, suspected to be T. saginata or T. asiatica, was carried out during exploratory laparotomy, which was followed by an uneventful postoperative period. In addition to case presentation, we systematically review published case reports on taeniasis-related intestinal perforation. A learning point from this case is clinician should maintain a clinical suspicion of taeniasis as a possible cause of intestinal perforation in endemic areas.
We’ve always been antagonistic: algorithmic resistances and dissidences beyond the Global North
Authors: Pereira Gabriel , Moreschi Bruno , Mintz André , Beiguelman Giselle
Published: February 2022

In this article we suggest that otherwise unacknowledged histories of technological antagonism can help us (artists, activists, and researchers) to more deeply appreciate the foundations on which we develop activist resistances to contemporary computing. Departing from the case of Brazil, our goal is to bridge historical and contemporary perspectives by: (1) discussing the everyday practises of technological dissidence in the country, and how appropriation has been used to resist unequal power structures; (2) presenting how particular tactical ruptures in the history of art and media activism have sought to contaminate and re-envision networked technologies; (3) exploring the particular notions of algorithmic antagonism that two contemporary projects (PretaLab/Olabi and Silo/Caipiratech) advance, and how they relate to their historical counterparts. In sum, these different threads remind us that we’ve always been antagonistic, and that recognizing a longer genealogy of technological dissidences and ruptures can strengthen current practises against algorithmic oppressions.
Do UN peace operations lead to more terrorism? Repertoires of rebel violence and third-party interventions
Authors: Di Salvatore Jessica , Polo Sara M. T. , Ruggeri Andrea
Published: February 2022

Recent research suggests that UN peacekeeping operations (PKOs) reduce conventional violence. However, rebel groups have been increasingly using a combination of conventional and non-conventional violence, for example, terrorism. Little is known about whether and under which conditions PKOs shape rebels’ incentives to resort to more terrorism. At the same time, existing research on the use of terrorism in civil wars primarily focuses on domestic factors, thus overlooking the impact of external shocks such as the deployment of PKOs. We argue that PKOs can have critical unintended consequences inducing tactical adaptation in rebel violence as they alter the government-rebels balance of power. Particularly, rebel groups that are militarily strong prior to the UN arrival are incentivized to escalate terrorist violence to overcome the physical barrier imposed by PKO forces and improve their bargaining position vis-à-vis the government. Weaker groups, which in the absence of PKOs are more likely to use terrorism, have not only limited capacity but also fewer incentives to escalate terrorism when PKOs deploy. Leveraging new disaggregated data on rebel terrorist attacks during civil wars, we provide the first global actor-level analysis of the relationship between PKO deployments and changes in rebels’ tactical preferences for terrorist violence. We find that, conditional on initial government-rebels power relations, PKOs can make terrorism the weapon of the strong. Our study sheds light on the unintended effects of peacekeeping, the causes of terrorism, and offers important policy implications for several current PKOs deployed in the midst of violence.
A transition of power in opioid substitution treatment: Clinic managers' views on the consequences of a patient choice reform
Authors: Andersson Lisa
Published: February 2022

Objectives: Opioid substitution treatment (OST) is often described as a strict and highly regulated treatment method, in which patients have limited influence over their treatment. In 2014, a reform was introduced by the regional council of Skåne in southern Sweden, which allowed OST patients to choose their treatment provider, thus transferring power from care providers to patients. The aim of this study was to examine what this increase in patient influence has meant for the clinics that provide OST in Skåne, and how these clinics have dealt with the new competitive situation that has arisen following the introduction of the reform. Methods: The study is based on two waves of semi-structured interviews with clinic managers at all OST clinics in Skåne. Results: The clinic managers described the increase in patient influence as a positive change, which had led to the patients being treated with more respect. The competition among clinics was expressed, among other things, in the form of differing views on the prescription of benzodiazepines, which initially gave rise to dissatisfaction among clinics with a more restrictive approach to such prescriptions. The reform did not lead to any clear diversity between clinics, apart from different approaches to the prescription of benzodiazepines. The incentive for competition-based diversity is, however, limited by the strict national regulatory system and by the reimbursement system, which restricts the ways in which clinics can conduct treatment activities. Conclusion: OST-clinic managers were largely positive about the increased patient empowerment and the shift in power balance associated with the patient choice reform. The introduction of the reform did not lead to any clear diversity between treatment providers, apart from differing views on the prescription of benzodiazepines, which by some managers was regarded as unfair competition.
