Summary
Reaction wood formation (tension wood) in trees such as poplar is a response to stress and environmental factors. Tension wood is a rich source of cellulose that can be used for products including paper or biofuels and is thus a target product in forestry. This study aimed to evaluate the formation of tension wood in two-year-old saplings of Populus alba by using alternate bending, nitrogen fertilization, and gibberellin hormone. Saplings were bent alternately in one or another direction every month during the growing season, fertilized twice at the beginning and in the middle of the growing season, and treated with gibberellin early in the growing season. The physical and anatomical characteristics of the wood were studied after the end of the growing season. Evaluation of transverse sections of specimens stained with safranin/Astra-blue showed that, compared with straight saplings, alternate bending saplings had a wider tension wood area in the growth ring and clear formation of a gelatinous layer. The wood of alternate bending saplings with nitrogen fertilization and gibberellin hormone had a higher wood density, greater longitudinal shrinkage, and less radial and tangential shrinkage than saplings with other treatments. Moreover, the alternate bending saplings treated with nitrogen fertilization and gibberellin hormone had tension wood with the largest vessels, the lowest vessel density, and the smallest total vessel lumen area than saplings with other treatments. Wood fibers of treated saplings also had the thickest wall with the smallest fiber and lumen diameters. Overall, the bending treatment with the addition of nitrogen fertilization and gibberellin hormone was the most effective for the stimulation of tension wood formation in terms of volume and intensity.
The Will to Fight: Combat, Morale, and the Experience of National Army Soldiers during the Greek Civil War, 1946–1949
Authors: Tsoutsoumpis Spyros 
Published: April 2022

Abstract
Why do soldiers fight? How do they deal with the exigencies of warfare? What methods are used by military establishments to control their rank and file and motivate them? This article addresses these questions by analysing the experience of national army soldiers during the Greek Civil War (1946–1949). The research on the Greek National Army has been dominated by top-down studies that focus on issues such as tactics, logistics and the role of senior military leaders. Accordingly, the perspective and experiences of ordinary soldiers have been largely overlooked. As a result we know very little about the factors that led soldiers to take an active part in combat, their understanding of the war and how they tried to cope with the exigencies of warfare. The article fills this gap by shifting the focus to the rank and file of the Greek National Army. It explores their everyday lives, discusses the methods used by the army to shore up morale and motivate the rank and file and analyse the soldiers’ responses to these efforts. In doing so, it contributes new insights into the experiences of soldiers and the conduct of the Civil War.
The Peoples of Anatolia
Authors: LaBuff Jeremy 
Published: April 2022

Abstract
Studies of the peoples of Anatolia take for granted the existence and importance of regional ethnic communities on the peninsula when investigating issues of identity, ethnic origins, and cultural assimilation (especially Hellenization). In reviewing the scholarship, this work argues that such assumptions lead to problematic conclusions that ignore or poorly apply recent theoretical work on ethnicity and current critiques of the assimilation model. A critical consideration of this work leads to an appreciation for the somewhat limited, and at times non-existent, role of regional ethnicity in the experiences of the inhabitants and communities of Anatolia, who mainly promoted more local forms of belonging in the face of the attempted orderings of ethnographic and imperial discourses.
The Kiss of a Philosopher
Authors: Ellerman Carl P. 
Published: April 2022

AbstractMotivated by Socrates’ warning to avoid the kisses of beautiful people, given the risk of losing rational self-government if seduced by a beautiful face, this account of Heidegger’s seemingly apolitical, Socratic defense of philosophy is a warning about the corruption of reason that may issue from commerce with the deceptively beautiful arguments, or cognitive kisses, of philosophers. Particularly philosophers who have a political agenda, this having been true of Heidegger, whose philosophy was infected with a militant fascism antithetic to truth-seeking Socratic philosophers. The test of ideas developed by America’s pragmatic philosophers, Pierce, James, and Dewey, is presented as an antidote to the malignant arguments of Nietzsche and Heidegger, whose deceptively beautiful arguments were destructive to humankind. Concluding remarks identify current threats to rational self-government writ large, by focusing on our postmodern information age in which almost anyone can become a spellbinding producer of deceptively beautiful, virulent information in cyberspace.

Published: April 2022

Background Resuscitative endovascular balloon occlusion of the aorta (REBOA) provides hemodynamic support to patients with non-compressible truncal hemorrhage. As cardiac output increases due to aortic occlusion (AO), aortic diameter will increase as a function of compliance, potentially causing unintended flow around the balloon. Materials and Methods Swine (N = 10) were instrumented to collect proximal mean arterial blood pressure (pMAP), distal MAP (dMAP), balloon pressure (bP), balloon volume (bV), and distal aortic flow (Qaorta). A 7-Fr automated REBOA catheter was positioned in Zone 1. At T0, animals underwent 30% total blood volume hemorrhage over 30 min followed by balloon inflation to complete AO. Automated balloon inflation occurred from T30-T60 when Qaorta was detected. Period of interest was T55-T60, while the balloon actively worked to maintain AO during transfusion of shed blood. Results Median weight of the cohort was 73.75 [IQR:71.58-74.45] kg. During T40-T55 and T55-T60, median pMAP was 88.95 [IQR:76.80-109.92] and 108.13 [IQR:99.13-119.51] mmHg, P = 0.07. Median Qaorta during T40-T55, and T55-T60 was 0.81 [IQR:0.41-0.96], and 1.53 [IQR:1.07-1.96] mL/kg/min, P = 0.06. Median number of balloon inflations during T40-T55 was 0.00 [IQR:0.00-0.75] and increased during active transfusion to 10.00 [IQR:5.25-14.00], P = 0.001. Discussion In clinical practice, following initial establishment of AO, progressive balloon inflations are required to maintain AO in response to intrinsic and transfusion-mediated increases in cardiac output, blood pressure, and aortic diameter.
Decreasing public interest in social psychiatry: An infodemiological study of worldwide Google search volumes from 2004 to 2021
Authors: Alibudbud Rowalt 
Published: April 2022

Background: While mental disorder is an ‘intrinsically social phenomenon’, social psychiatry has been reportedly declining. Addressing public interests in social psychiatry was among the suggestions to address this decline. In recent years, public interest in social psychiatry can be explored using Google Trends, an increasingly important infodemiological tool. Objective: This study determined changes in global online public interest in social psychiatry from January 2004 to December 2021 using Google search volumes. Methods: Search query using this keyword, ‘Social Psychiatry (Topic)’, was made using the Explore feature of Google Trends. The Region and Time Filters were set to ‘Worldwide’ and January 2004 to December 2021, respectively. Afterward, the search volumes, country ranking, queries, and topics returned by the Google Trends system was described and compared. Results: There was a generally decreasing trend in search volumes for social psychiatry where it decreased almost 10 times between 2004 and 2021. Only 11 countries were listed in Google Trends’ ranking with the top countries including Austria, Germany, and Switzerland. Search-related topics and queries were about social psychiatry related concepts, related academic discipline, human resources, social interventions, and education activities Conclusions: The findings suggest that there is a decreasing public interest in social psychiatry. To improve this, social psychiatry can address public expectation through improving its connection with allied social sciences, increasing its educational activities, and expanding its social intervention services.
The associated effects of parent, peer and teacher attachment and self-regulation on prosocial behaviors: A person-and variable-centered investigation
Authors: Yang Pei-Jung , McGinley Meredith 
Published: April 2022

Adolescence is a critical juncture in the development of prosocial behaviors, which contribute to the overall well-being of youth. Thus, it is important to understand how multiple socialization agents and self-regulation simultaneously foster prosocial behaviors. Using both variable-centered and latent person-centered approaches, the current study examined the relative, concurrent contribution of multiple socialization agents (parent, peer, and teacher attachment) and self-regulation on Taiwanese adolescents’ global prosocial behaviors. This study included 1473 Taiwanese high school students (50.4% junior high schoolers, 57.9% females, Mage = 14.87 years) who completed measures of parent, peer, and teacher attachment, self-control, and prosocial behaviors. Four profiles emerged from the person-centered approach. The profile with highest scores on self-control and all measures of attachment reported the highest prosocial behaviors. The other three profiles differed in their attachment patterns but demonstrated roughly similar levels of self-control. Among the three profiles, the groups with the lowest scores on prosocial behaviors appeared to have low to moderate attachment quality, whereas the group with high peer attachment scored significantly higher in prosocial behaviors than the other two groups. Results from the variable-centered approach found no direct effects of parent attachment on prosocial behaviors, though effects of self-control and peer and teacher attachments were evident. Our findings suggest that the quality of attachment and self-regulation commonly promote prosocial behaviors in youth. Furthermore, peer and school-based relationships may serve as unique and salient socialization contexts for prosocial behaviors during adolescence. Limitations and recommendations for future research were discussed.

Published: April 2022

Background: Catechol-O-methyltransferase (COMT) regulates cortical dopaminergic transmission and prefrontal-dependent cognitive function. However, its role in other cognitive processes, including emotional processing, is relatively unexplored. We therefore investigated the separate and interactive influences of COMT inhibition and Val158Met (rs4680) genotype on performance on an emotional test battery. Methods: We recruited 74 healthy men homozygous for the functional COMT Val158Met polymorphism. Volunteers were administered either a single 200 mg dose of the brain-penetrant COMT inhibitor tolcapone or placebo in a double-blind, randomised manner. Emotional processing was assessed using the emotional test battery, and mood was rated using visual analogue scales and the Profile of Mood States (POMS) questionnaire across the test day. Results: There were no main or interactive effects of Val158Met genotype or tolcapone on any of the emotional processing measures or mood ratings. Conclusions: Our findings suggest that, at least in healthy adult men, COMT has little or no effect on emotional processing or mood. These findings contrast with several neuroimaging studies that suggest that COMT modulates neural activity during emotional processing. Thus, further studies are required to understand how COMT impacts on the relationship between behavioural output and neural activity during emotional processing. Nevertheless, our data suggest that novel COMT inhibitors under development for treating cognitive dysfunction are unlikely to have acute off target effects on emotional behaviours.
COVID-19 effect on perioperative findings of flexible/semi-rigid ureterorenoscopic lithotripsy: A match-pair analysis
Authors: Demirci Aykut , Hızlı Fatih , Başar Halil 
Published: April 2022

Purpose: If not treated on time with proper management options, urolithiasis cause serious morphologic and functional alterations in the involved renal units. Like many other pathologies, the diagnosis, treatment, and follow-up principles of patients with urinary stones have been negatively affected by the unestimated changes in the healthcare systems dealing intensively with COVID-19 patients. In this present study, we aimed to evaluate and present the possible effects of COVID-19 infection on the ureterorenoscopic stone treatment. Materials and methods: Clinical and procedural characteristics of 96 patients undergoing flexible and/or rigid ureterorenoscopy because of urolithiasis between March 2020 and January 2021 were evaluated in a retrospective manner. Obtained data were evaluated after match-pair analysis in a comparative manner between cases with a positive medical history of COVID-19 infection (Group 1, n: 48) and those without any COVID-19 infection (Group 2, n: 48). Results: There was no statistically significant difference between the two groups of cases with respect to age, gender, associated comorbidities, and stone characteristics (p > 0.05). The mean serum creatinine level was determined to be higher in Group 1 than in Group 2 (1.15 ± 0.59 mg/dl, 0.83 ± 0.21 mg/dl, p = 0.007, respectively). Evaluation of the operative parameters revealed longer mean time from diagnosis to surgery (33.5 ± 14.27 vs 12.12 ± 6.33 days, p = 0.001), operating time, median length of stay in hospital along with higher additional intervention rates, and Clavien-Dindo complication scores again in Group 1 (p < 0.05). Conclusion: Our results indicate that the presence of COVID-19 infection anamnesis may affect the clinical and operative parameters of ureteroscopic stone management in cases with urolithiasis due to the possible effects of renal units damage and longer waiting time. Urologists may be aware of these unestimated problems during and after the intervention to take necessary measures for a safe and successful ureteroscopic stone removal.

Published: April 2022

In the present research, a coupled Eulerian–Lagrangian model is developed to predict the forces and defects produced from AA6063 friction stir welding process. Furthermore, the obtained results from the developed model were validated experimentally by performing the welding process at different rotational and welding speed values. The results revealed an appearance of tunnel defect at all welded joints with surface flash. The current model successfully predicted both defects’ evolution. Additionally, it also generated force measurements comparable to those obtained experimentally. In addition, the developed Coupled Eulerian–Lagrangian model successfully predicted the generated force and the defects during friction stir welding process with maximum error of 14% and 18%. However, it failed in predicting the tunnel positions. In terms of the tensile strength, the largest tensile strength value was at 1250rpm and 50 mm/min, whereas the lowest one was at 1000 rpm and 25 mm/min. Moreover, the fracture locations were at the advancing side of all the welded joints.

Published: April 2022

Background: Quality management in healthcare is critical for hospitals and everyone in the loop —from physicians to support staff—needs to be aware of and involved in this process. Objectives: To assess the perception of employees about the quality management system (QMS) implemented at a tertiary care eye hospital in north India and to use it to identify scope for further improvement. Methods: This cross-sectional mixed-method study involved both questionnaire-based survey and an in-depth interview by a third party. The questionnaire had 12 questions to assess the changes in culture, infrastructure, environment, system, operation theatre and outpatient department. Employees shared their opinion about improvements brought by the QMS in eight years. Respondents were divided into five groups based on their job description: (i) doctors, (ii) technical staff (nursing/operation theatre/laboratory), (iii) optometrists/opticians/audiologists, (iv) patient care executives and (v) human resources/administration/others. Results: Of the 73 employees interviewed, 94.5% perceived an improved treatment and care process and 91.8% perceived improved treatment results. According to 83.6% of the employees, they were encouraged to report patient safety concerns and 71.2% saw improved incidence and adverse event management. The QMS has increased patient satisfaction according to 83%, while 91.8% felt it improved the profile of the hospital. The employees stated no negative effects of the QMS except a long waiting time of the patients and the duplication of paperwork. Conclusion: QMS has brought many positive changes across the hospital. Still, there is scope to reduce the patient waiting time and paperwork duplication.

Published: April 2022

Objective: To explore the feasibility and safety of Guidewire-Balloon Entrapment Technique (GBET) for the recanalization of thoracic central vein occlusions (TCVOs) in hemodialysis patients. Methods: A retrospective observational study was conducted using data from 28 patients who required the establishment or maintenance of hemodialysis access and were treated with GBET for the recanalization of right-sided TCVOs from January 2017 to April 2021. Of the patients, 27 required tunneled cuffed catheter (TCC) placement or exchange, and 1 had an outflow tract occlusion of the Brescia-Cimino radio cephalic arteriovenous fistula (AVF). Results: A total of 26 patients successfully underwent TCC exchange and placement using GBET; 1 patient underwent successful recanalization of an occlusion of the outflow tract of the right Brescia-Cimino AVF; and 1 patient underwent successful TCC placement in the left internal jugular vein (LIJV) after the failure of TCC placement in the right internal jugular vein (RIJV). The success rate for GBET was 27/28 (96.43%), and there were no major complications. Conclusion: GBET is a safe and effective method for the recanalization of right-sided TCVOs, especially for TCC exchange and placement, and can be used as a safe and easy approach for TCVO recanalization.

Published: April 2022

Background: Autogenous arteriovenous fistula (AVF) is the best vascular hemodialysis access for terminal chronic renal failure patients but is prone to thrombosis. Pathogenic mechanisms of AVF thrombus are thus largely explored. As exosomes carry genetic content from cell of origin. We hypothesized that miRNAs in serum exosomes are promising regulators of AVF thrombosis. Methods: Serum exosomes were isolated from maintenance hemodialysis (MHD) patient, miRNAs profile of the exosomes was obtained by high throughput sequencing, six miRNAs (miR-144-5p, miR-18a-5p, miR-200a-3p, miR-200b-3p, miR-141-3p, and miR-429) were determined as candidates examined by RT-PCR, cells transfected with miR-200b-3p mimics demonstrated significantly increased mRNA levels of VEGF and Ang-II, the relationship between miR-200b-3p and VEGF or Ang-II was performed by adual luciferase reporter assay. Results: There are 43 miRNA down-regulation and 15 miRNA up-regulation between MHD group and MHD+Thrombus group, the expression levels of miR-200b-3p and miR-429 in MHD with thrombus were significantly increased ( p < 0.001, p < 0.05). Inhibited miR-200b-3p expression level can increase VEGF mRNA and protein expression levels and decrease Ang-II mRNA and protein expression levels. Furthermore, we also identified that miR-200b-3p targets VEGF and Ang-II. Conclusion: Our study indicates that serum exosome-derived miR-200b-3p regulate VEGF and Ang-II to increase intimal hyperplasia to induce AVF thrombosis. Besides miR-200b-3p, miR-200 family may also play a regulatory role in AVF thrombosis.
The Relationship of Circulating Proprotein Convertase Subtilisin/Kexin Type 9 With TSH and Lipid Profile in Newly Diagnosed Patients With Subclinical and Overt Hypothyroidism
Authors: Sadik Noha Adly , Rashed Laila Ahmed , El-Sawy Shereen Sadik 
Published: April 2022

Introduction: Overt and subclinical hypothyroidism are mostly associated with dyslipidemia, an essential cardiovascular risk factor. Recently, thyroid stimulating hormone (TSH) was identified to have a direct role on lipid metabolism via increased expression of hepatic proprotein convertase subtilisin/kexin type 9 (PCSK9). PCSK9 plays a crucial role in lipid metabolism via regulating LDL-C levels. Thus, we aimed to evaluate circulating PCSK9 levels and to assess its relationship with serum TSH and lipids in newly diagnosed patients had overt and subclinical hypothyroidism. Methods: In our study, we enrolled 60 newly diagnosed untreated patients with overt and subclinical hypothyroidism and 30 euthyroid subjects served as the control group. Serum TSH, FT4, FT3, lipid profile and circulating PCSK9 levels using ELISA kits were measured in all subjects. Our data were summarized using mean ± SD or median and interquartile range. Correlations between PCSK9 expression levels and different variables were done using Spearman correlation coefficient. Results: Circulating PCSK9 median levels were significantly increased in patients had overt and subclinical hypothyroidism (12.45 ng/ml, 7.50 ng/ml respectively) compared to the control group (3.30 ng/ml) ( P < .001). Circulating PCSK9 levels significantly correlated positively with TSH, total cholesterol, triglycerides, and BMI, and negatively correlated with FT4 and FT3 among all studied subjects. Using multivariate regression analysis TSH was the only significant independent predictor of circulating PCSK9 ( P < .001). Conclusion: Our results supports the new implication of TSH in lipid metabolism via the significant association with PCSK9. Whether this relationship between TSH and PCSK9 is a cause or just an association needs further evaluation.
