Ordem social baseada no apoio mútuo: razão anarco-magonista e povos indígenas em Oaxaca, México
Authors: Maldonado Alvarado Benjamin
Published: December 2022

O movimento anarquista mexicano denominado Magonismo encontrou no modo de vida indígena a experiência histórica coletiva que levaria à organização da sociedade libertária e autogestionária após o triunfo da revolução contra o Estado, apesar de considerarem esse modo de vida recentemente derrotado pelo capitalismo. Mas a comunalidade ou modo de vida comunal das comunidades indígenas mesoamericanas ainda está amplamente viva em lugares como Oaxaca, razão pela qual continua sendo a base para a organização de um mundo livre e seus jovens são cada vez mais treinados para recuperá-la em seus sentidos de resistência, rumo à libertação.

Published: December 2022

: This study was aimed at assessing adaptation and bonding of discontinuous (short) glass fiber-reinforced composite to intraradicular dentin EverX Flow (GC Corporation, Tokyo, Japan), when used as intracanal composite filling and anchorage instead of traditional fiber posts. (2) Methods: Seventy intact extracted human teeth were endodontically treated and randomly divided into 6 groups (n=10), depending on the materials used in the post space. In Group 1, a 2-bottle universal adhesive G2 Bond Universal + EverX Flow were tested. In group 2, a single-component universal adhesive G-Premio Bond + EverX Flow were used. In groups 3 and 4 the same materials are tested, but after cleaning of the canal walls with 17% EDTA and final irrigation with 5.25% NaOCl Ultrasound Activated. In the last three Groups (5-7) traditional prefabricated GC Fiber Posts 1.6 mm silanized with G-Multi Primer for 1 minute are cemented with a dual-cured composite resin cement (GradiaCore), after ultrasonic irrigation in the groups 6 and 7. In each group, 1 mm-thick slices from each sample (n=10) were cut for light microscope and SEM inspection for study materials adaption to the dentin and for measuring push-out strength of post / cemement material to the dentin / prefabricated post. These results were statistically analyzed: as the data distribution was not normal, the Kruskal-Wallis Analysis of Variance by Ranks had to be applied. The level of significance was set at p<0.05. Results: Push-out forces varied between 6.66-8.37 MPa. No statistically significant differences were recorded among the groups. Microscopic examination showed that ultrasonic irri-gation increased adaptation of the materials to the dentin surface. There was a trend of higher bond strength among the tested groups when EverX Flow was used. Also, the type of failure was more often cohesive when ultrasonic irrigation and two-step adhesive system were used. Conclusions: Within the limitations of this in vitro study, it may be concluded that when EverX Flow was used for intracanal anchorage in the post-endodontic recon-struction, similar push-out retentive forces and strength to those of traditional fiber posts cemented with particulate filler resin composite cements were achieved. Although further studies are necessary, EverX Flow represents an effective alternative to traditional fiber post adhesion in particular when used in combination with the two-step adhesive system and ultrasonic activation.

Published: December 2022

The goal of our study was to examine the effect of regional characteristics of living environment on individual a priori and a posteriori dietary patterns of the Russian population. For the analysis, we used cross-sectional data from the Epidemiology of Cardiovascular Diseases in the Regions of the Russian Federation study of 2013-2014. The sample included 18,054 men and women 25-64 years of age from 12 regions. Based on the frequency of consumption of basic foods, four a posteriori empirical dietary patterns (EDPs), along with an a priori cardioprotective dietary pattern (CPDP) were identified. To describe the regional living environment, 5 regional indices were used. The adherence to the meat-based EDP was directly associated with deterioration of social living conditions and the more northerly location of the region of residence. The probability of CPDP increased with deterioration of social living conditions, an aggravation of demographic crisis, higher industrial development of the region, as well as with a decline in the economic development of the region, income and economic inequality of the population. We detected some gender-dependent differences in associations. The revealed patterns reflect the national dietary preferences of Russians, and regional indices characterize the effect of living environment.

Published: December 2022

Pregnancy is a dynamic state with multiple metabolic changes occurring including insulin resistance. Gestational diabetes mellitus (GDM), a form of diabetes that appears during pregnancy, develops if metabolic aberrations occur, in particular, in normal pregnancy-induced insulin resistance. Multi-omics is a powerful approach for uncovering the mechanisms driving metabolic change in different physiologic and pathologic states. A recent study demonstrated that the gestational gut microbiome mediates pregnancy metabolic adaptations through effects on gut indoleamine-2,3 dioxygenase 1 activity and the production of kynurenine. Using the dataset generated from this highly controlled study, we performed a comprehensive analysis of the pregnancy-specific physiological and metabolic profiles, 16S rRNA microbiome, and plasma untargeted LC-MS metabolome data. To facilitate the utilization of these analysis results by other researchers, we developed MOMMI-MP, a database that provides an easy-to-use platform to browse and search differential abundant microbial taxa and metabolites, and to examine metabolic pathways. The datasets consist of data collected from 3 genetically diverse strains of mice (C57BL/6J, CD1, and NIH-Swiss) over 6 time points during the gestational (days 0, 10, 15, and 19 during gestation) and postpartum (days 3 and 20 after delivery) states, totaling 180 samples for each strain. The computational results are presented in various tables and plots, and organized in MOMMI-MP to empower exploratory analyses by other researchers. In conclusion, MOMMI-MP is a resource to facilitate the investigation of novel mechanisms governing metabolic changes during pregnancy.

Environmental physical and chemical factors controlling the abundance and biodiversity of zooplankton in permafrost-affected lakes are poorly known yet they determine the response of the ecosystems to on-going climate change and water warming. Here we assessed the current status of zooplankton communities of lake ecosystems in the North-West of the Bolshezemelskaya tundra (Nenets Autonomous district), and provide new information about the composition and structure of zooplankton. Results demonstrate that the structure of zooplankton communities is influenced by morphometric features of lakes and the degree of their overgrowth by macrophytes. According to the level of zooplankton development, most tundra lakes were of the oligotrophic type with an average biomass of up to 1 g/m3. The largest number of species was observed in zooplankton communities of small lakes with an area of up to 0.02 km2 and overgrown with macrophytes. The analysis of factors that influence the formation of the lakes zoocenosis demonstrated that the species composition and quantitative characteristics of zooplankton are chiefly controlled by pH and water mineralization. A comparison of the results obtained with the literature data on the lakes of this region collected 60 years ago confirms that the ecosystems of the studied lakes are in a stable state. Overall, these new insights will improve our knowledge of factors controlling the zooplankton spatial dynamics in unique but quite abundant thermokarst lakes of NE European Tundra, subjected to on-going climate warming.

Published: December 2022

This study evaluated the anti-inflammatory effects, protection of gut barrier integrity, and stimulation of phagocytosis in peripheral cells of a nutritional supplement based on a synergistic combination of yeast-based ingredients with a unique 1,3/1,6-glucan complex and a consortium of postbiotic Saccharomyces cerevisiae rich in selenium and zinc. The anti-inflammatory effect in Caco-2 cells in the presence and absence of a pro-inflammatory challenge (tumour necrosis factor alpha [TNF-α]/interferon gamma [IFN-ɣ]) showed statistically significant reductions of IFN-ɣ induced protein-10 (IP-10), and monocyte chemoattractant protein-1 (MCP-1) levels vs. controls (p < 0.001). Disruption of the gut integrity in the presence or absence of Escherichia coli (ETEC H10407) showed transepithelial electrical resistance (TEER) values higher in the ABB C1® group after 6 hours of testing. Spontaneous build-up of the gut epithelium monolayer over 22 days was also greater in the ABB C1® condition vs. a negative control. ABB C1® showed a significantly higher capacity to stimulate phagocytosis as compared with controls of algae β-1,3-glucan and yeast β-1,3/1,6 glucan (p < 0.001). This study supports the mechanism of action by which ABB C1® may improve the immune response and be useful to prevent infection and allergy in clinical practice.
Genetic and Chemical Controls of Sperm Fate and Spermatocyte Dedifferentiation in Caenorhabditis elegans
Authors: Park Youngyong , Gaddy Matthew , Hyun Moonjung , Jones Mariah E , Aslam Hafiz M , Lee Myon Hee
Published: December 2022

Using the nematode C. elegans germline as a model system, we previously reported that PUF-8 (a PUF RNA-binding protein) and LIP-1 (a dual-specificity phosphatase) repress sperm fate at 20°C and the dedifferentiation of spermatocytes into mitotic cells (termed "spermatocyte dedifferentiation") at 25°C. Thus, double mutants lacking both PUF-8 and LIP-1 produce excess sperm at 20°C, and their spermatocytes return to mitotically dividing cells via dedifferentiation at 25°C, resulting in germline tumors. To gain insight into the molecular competence for spermatocyte dedifferentiation, we compared the germline phenotypes of three mutant strains – fem-3(q20gf), puf-8(q725; fem-3(q20gf), and puf-8(q725); lip-1(zh15). Both fem-3(q20gf) and puf-8(q725); fem-3(q20gf) mutants produced excess sperm like puf-8(q725); lip-1(zh15) double mutants. Our results show that spermatocyte dedifferentiation was not observed in fem-3(q20gf) mutants, but it was more aggressive in puf-8(q725); lip-1(zh15) than in puf-8(q725); fem-3(q20gf) mutants. These results suggest that MPK-1 (the C. elegans ERK1/2 MAPK ortholog) activation by removing the function of LIP-1 in the absence of PUF-8 promotes spermatocyte dedifferentiation. This idea was confirmed using Resveratrol (RSV), a potential activator of MPK-1 and ERK1/2 in C. elegans and human cells. Notably, spermatocyte dedifferentiation was significantly enhanced by RSV treatment, and its effect was blocked by mpk-1 RNAi. We, therefore, conclude that PUF-8 and MPK-1 are normally required to inhibit spermatocyte dedifferentiation and tumorigenesis. Since these regulators are broadly conserved, we suggest that similar regulatory circuitry may control cellular dedifferentiation and tumorigenesis in other organisms, including humans.

Published: December 2022

Philanthropy has been very beneficial for social welfare. However, the regulation of philanthropy that governs philanthropy management institutions has not been successful in enhancing the welfare of the poor, particularly in post-COVID-19 tourism areas. This research explains the issue from a doctrinal normative perspective. The results indicate that the characteristics of philanthropy norms work as economic capital assistance, the regulation also should be able to identify the objectives and goals to be achieved for human welfare. Moreover, state and private institutions manage philanthropy independently, freely, and responsibly performing economic empowerment is developed with the existence of institutions that manage resources derived from philanthropic activities. These activities are based on the recommendations which are contained in scriptures and hierarchical juridical legitimacy containing transcendent norms.

Published: December 2022

The purpose of this research is to examine the reflections of the strategic behaviors preferred by managers on motivation at workplace in a chaotic environment. In this context, first of all, the strategic behavior characteristics of the managers were determined by considering the characteristics of the chaotic environment and then they were associated with the motivational situations. Quantitative method was used in the research and the data were obtained through face to face survey method. According to the results of the research, managers prefer more strategic behaviors related to creating alliances in a chaotic environment. Strategic behaviors that have the highest impact on motivation in the workplace are the using power sources and creating alliance. However, if a more holistic assessment is to be made, it seems that in chaotic environments, managers prefer to create alliances as a strategic behavior to reduce the impact of negative external conditions on internal dynamics or increase resistance. And this behavior not only prevents the negative effects of the chaotic environment, but also important contributes to the continuity of motivational conditions in the workplace.

Published: December 2022

This paper aimed to develop a valid and reliable measurement scale for green organizational climate. Both qualitative and quantitative research methodologies were applied. In the research, the three-stage scale development process proposed by Schwab (1980) was be used. The conceptual framework were first clarified and a proposal pool were created by compiling the expressions in scale through a qualitative exploration study, which includes literature review, in-depth interviews and focus group studies using deductive and inductive methods. Expert opinions were sought for the examination of face validity and content validity. After the pilot application, draft scale was applied to 750 managers of businesses operating in different sectors in various provinces of Turkey. According to the results of the exploratory factor analysis, 21 items and 4 dimensions were extracted, namely green economic climate, green social climate, green digital climate, and green bureaucratic climate. The results of confirmatory factor analysis indicated that the measurement items developed were had an acceptable level of compatibility. The cronbach alpha coefficients had sufficient reliability in all dimensions. As a result, it was seen that the green organizational climate scale is a valid and reliable measurement tool.
Transformation of the Institutional Political Economy of Japan: From Rice Field Property Reform to the Zaibatsu
Authors: DOĞRUL Mürsel , KORKUT Cem
Published: December 2022

This article examines the evolution of the institutional political economy of Japan from feudal to modern times and conceptualizes the origins of the Zaibatsu (financial clique of Japan) heritage, which has been around for centuries. The historical events were considered based on their impact on economic transformation while the methodology is based on the theoretical framework of institutional economics. In this way, the Japanese economy has been examined from a variety of angles within the contexts of the Edo Period, Meiji Reforms, and World Wars. We assert that there is a historical continuity between the rice field property reforms of the Edo Period and the success of the zaibatsu. The linkages between the state, business, and labor illuminate the economic evolution of Japan, which is clearly stated throughout the research with regard to the material and nonmaterial components. As a result, while distinguishing itself from the enormous and present literature on the Japanese economy, this study stresses rice field reforms and their continued repercussions on the main institutions of Japan’s economic miracle.

Published: December 2022

Fast development in the technology and the intense competition have driven banks to spend considerable money on transforming from traditional banking business to digital banking business to sustain competitive advantage. Since the changing habits, customers are demanding new approaches to access financial services through both secured and unsecured digital channels. This study develops and tests a modified theoretical model based on the Unified Theory of Acceptance and Use of Technology (UTAUT) to analyse how customers respond to digital banking products or services in New Zealand from behaviour intention perspective. This study finds that the individuals’ behaviour intention towards digital banking products or services can be predicted from performance expectancy, effort expectancy, and service quality conditions. Besides, this study discovers that customer gender, age and experience are having moderating influence when determining the intention of using digital banking products or services. Study contributes to knowledge in the field of individual technology acceptance research. It demonstrates that customer satisfaction also plays a major role in the digital banking context.

Authors: Park Hyoungjin Park
Published: December 2022

The aim of this study was to compare the postural control of women with knee OA and healthy women peers and to determine the effect of knee OA on postural control. Thirty-two individuals, sixteen women with knee osteoarthritis(52.12±10.69)and sixteen healthy women(51.00±10.00)who were same age (±3yr), were evaluated on postural control as measured by a NeuroCom EquiTest. Outcomes included equilibrium scores, sensory analysis ratios, sway energy score, and latenciesfrom sensory organisationtest, motor control test, and adaptation testandwere examined using the independent t-test.Equilibrium scores (in condition 1: p=0.030, condition 3: p=0.019, condition 4: p=0.045, condition 5: p=0.010, condition 6: p=0.041, and Composite value: p=0.011), strategy score (Strategy 5: p= 0.015), sensory analysis ratios (vestibularratio: p=0.013 and managementratio: p=0.023), and latencies (largeforward: p=0.020 and comprehensivelatency: p=0.016) were significantly better in the healthy women group. The presence of knee OA had an impact on the sensory system's effectiveness and its utilization in postural control. Lower values of equilibrium scores, strategy scores, sensory analysis ratios for women knee OA group were evidence of larger displacements of the center of gravity in the forward–backward direction suggesting that women knee OA group was unable to maintain balance compared to healthy knee controls. Also, women with knee OA displayed a longer neuromuscular response latency to balance perturbations, indicating a reduced ability to begin in recover balance quickly following an unexpected disturbance. This observation should be taken into account in the fall prevention, especially, individuals should place in dynamic situations with conflicted sensory environment, as these are found in daily life.

Published: December 2022

This study aimed to systematically review the current scientific literature on game-related statistics (GRS) that better discriminate between basketball winning and losing teams, and to identify the magnitude of the difference of the most frequently cited GRS between winning and losing teams via meta-analysis. A systematic search of the databases Web of Science, Scopus, SPORTDiscus, PubMed, Science Direct, Latindex, Scholar Google, and Scielo was performed. Keywords addressed discriminant analysis, game-related statistics, discriminant factors, determinant factors, game outcome, match analysis, winning and losing,and basketball. Data from 20 out of 533articles were eligible to be extracted. Structural Coefficients (SC)values were considered relevant for analysis when ≥0.32. Results indicated that defensive rebounds and assists were classified as good (SC ≥ 0.46) or very good (SC ≥ 0.56) discriminant factors. Both were the most frequently GRS cited as discriminant factors, regardless of location, phase of the competition, or opponent’s level. Based on these indicators, eight studies were included for meta-analysis.Meta-analyses showed that winning teams have at least six more defensive rebounds (95% CI = 4.22 -7.99; p < 0.0001) and around four more assists than losing teams (95% CI = 3.14 -4.50; p < 0.0001). Coaches should emphasize defensive rebounding and assisting drills intheir practice planning to improve the likelihood of winning games.

Published: December 2022

Seja 𝑛 um número inteiro não negativo. Neste trabalho consideramos a usual sequência de Pell, a qual denotamos por P𝑛 e o elemento de posição 𝑛 ≥ 0 desta sequência por 𝑃𝑛. Bicknell (1975) afirma que a sequência de Pell possui propriedades aritméticas semelhantes as propriedades da sequência de Fibonacci ou Lucas (que não serão tratadas aqui), no entanto é pouco conhecida ou difundida, sendo restrita a pesquisadores, estudiosos ou diletantes em Teoria dos Números. Com a curiosidade atiçada pela afirmação de Bicknell, estudamos (revisão bibliográfica) algumas propriedades desta sequência numérica. Por exemplo, Santana e Díaz-Barrero (2006) apresentam um estudo sobre algumas somas parciais de termos 𝑃𝑛, isso nos instigou a fazermos algumas observações e conjecturar alguns resultados, e assim obtemos alguns resultados. Em especial Santana e Díaz-Barrero (2006) mostram que, a soma dos primeiros 4𝑛 + 1 elementos de P𝑛 é um quadrado perfeito. Nossa principal contribuição é uma caracterização do divisor ímpar de 𝑃𝑛, sendo 𝑛 ímpar e 𝑃𝑛 composto.

Novel Method for Characterizing the Mechanical Properties of the Cement Sheath Based on Hollow-Cylinder Specimen and Multiaxial Load Tests
Authors: Su Donghua , Li Jin , Huang Sheng , Li Zaoyuan , Wu Xuning
Published: December 2022

Mechanical properties such as Young's modulus, Poisson's ratio, and strength are important parameters for evaluating the cement sheath integrity. However, the current triaxial testing methods for the mechanical properties of intact-cylinder cement specimens ignore the “ring” shape of the wellbore cement sheath and its nonuniform 3D stress distribution, which may lead to deviations from the actual mechanical properties of the wellbore cement sheath that can affect the theoretical analysis results. In this study, we designed a hollow-cylinder cement specimen to address the aforementioned conditions and conducted uni, tri, and multiaxial compression tests to analyze the differences in the deformation, damage, and mechanical failure of the hollow- and intact-cylinder cement specimens. It was found that under the same confining pressure, the Young’s modulus of the hollow-cylinder cement specimen with hole pressure was approximately 1.2 times that of the intact-cylinder cement specimen; however, the difference in Poisson’s ratio was not significant. The uniformity of the radial and circumferential stress distributions in the hollow-cylinder cement specimens was the main factor affecting the volumetric strain curves and the damage threshold. Under tri and multiaxial compression conditions, the deviatoric stress of the hollow-cylinder cement specimens was higher than that of the intact-cylinder cement specimens. Compared with the Mohr-Coulomb criterion, the twin-shear unified strength theory can more accurately reflect the relationships between the radial, circumferential, and axial stresses and the strength of the hollow-cylinder cement specimens. Through a failure test of the cement sheath based on a self-developed wellbore simulation device, it was verified that the mechanical properties of the hollow-cylinder cement specimens can better reflect the failure law of the wellbore cement sheath compared with intact-cylinder cement specimens. The findings of this study can contribute to the understanding of the mechanical behavior of wellbore cement sheaths.
Real-Time Outdoor Localization Improvement for IoT Anchor Nodes

Published: December 2022

Real-time localization improvement is needed in most Internet of Things (IoT) applications that require accurate knowledge of the physical location of IoT devices, especially in the areas that having a weak GPS signals or in moving objects like smart bike-sharing, robots, and off- roads vehicles. Recently, most outdoor localizations use a hybrid mechanism integrating some IoT devices occupying with GPS (Anchor Nodes) and others IoT devices with wireless sensors nodes like LoRaWAN (without GPS-Unknown node). This hybrid method employed to achieve low power consumption and low cost solution. Our proposed work focuses on determining the Anchor node locations with high accuracy to enhance the overall accuracy of all IoT nodes. To achieve this goal, the installation of low power consummations and low-cost localization sensors modules will be used in the proposed Anchor IoT node. These modules as inertial measuring unit (IMU) will integrate with a low cost Global Positioning System (GPS) module to enhance the locations accuracy of these IoT devices. Then, the proposed method will be implemented on AVR microcontroller (ATMega 128) to develop an IoT enhanced localization unit. The general structure of the proposed method from a mathematical point of view is presented with recursive algorithm update equations. Moreover, this paper will show how the IoT device’s state can be known accurately and at a high update rate (100Hz, 10 milliseconds).
Landslide deformation mechanism in buoyant and slide-prone strata in the Three Gorges Reservoir area, China
Authors: Xu Xiao-chuan , Xu Guang-li , Feng Fei , Xu Wei-dong , Mabi Awei
Published: December 2022

This paper describes the Baibao landslide that occurred in October 2017 within a Jurassic formation in Guojiaba town, Zigui County, Yichang city, China. The factors leading to this landslide include complex geological conditions, slide-prone strata, and fluctuating water level of the Three Gorges Reservoir. Borehole and field investigations indicate that the landslide can be divided into two parts: a medium to deep rock landslide and a partial soil sliding landslide. A comprehensive analysis of the monitoring data, including GPS, precipitation, inclinometer, and water reservoir level measurements, indicates that the Baibao landslide was caused mostly by buoyancy, as well as seepage. Rising reservoir water levels and concentrated pore water pressure at the leading edge of the slope softened the sliding mass. The reduced anti-sliding force allowed the landslide to occur and ultimately drag the rear slope. This study illustrates the landslide deformation mechanism and provides a useful reference for engineering projects in similar regions.

Published: December 2022

Background: To address the challenges of limited national data on the prevalence and nature of violence experienced by children, Rwanda conducted, in 2015-2016, the first National Survey on Violence among female and male children and youth aged 13-24 years. To further contribute to these efforts to fill existing data gaps, we used the Rwanda survey data to assess the prevalence and predictors of physical violence (PV) in children aged 13-17.
Methods: A nationally representative sample of 618 male and 492 female children were analysed. Nationally representative weighted descriptive statistics were used to analyse the prevalence of PV self-reported by children, and logistic regression models were applied to investigate its predictors.
Results: Sixty percent of all children, including 36.53% of male and 23.38% of female children, reported having experienced any form of PV in their lifetime. Additionally, 21.81% of male children and 12.73% of children reported experiences of PV within twelve months before the survey date. Older children (OR: 0.53 [0.40-0.72]), female children (OR: 0.43 [0.31-0.58]), and children not attending school (OR: 0.48 [0.31-0.73]) were less likely to be physically abused. However, sexually active children (OR: 1.66 [1.05-2.63]), children in households from the middle wealth quintile (OR: 1.63 [1.08-2.47]), children living in a larger family (OR: 1.55 [1.07-2.26]), and children who reported not feel close to both biological parents (OR: 2.14 [1.31-3.49]) had increased odds of reporting physical violence.
Conclusions: Higher rates of PV in children attending school werethe key finding. There is an urgent need to design and implement particular national interventions to prevent and reduce the incidence of PV in schools in Rwanda. PV was also associated with poor parent-child relations. Parents and other adult caregivers should be sensitisedto the consequences of PV on children and be urged to adopt positive parenting practices.
Fabry Disease: Screening and Analysis of the Associated Clinical Manifestations in Patients Attending Dialysis and Nephrology Clinics in Durban, South Africa
Authors: Singh Jillian , Benjamin Sherilene , Assounga Alain
Published: December 2022

Background Fabry disease is inherited in an X-linked manner in which the mutated gene inhibits the functioning of the alpha-Galactosidase-A enzyme causing a deficiency or absence of the enzyme, characterising it as a progressive, lysosomal storage disorder. Subsequently, the accumulation of globotriaosylceramide (Gb3) in the lysosomes causes damage to tissues and major organs. Fabry nephropathy is one of the major organ complications caused by Fabry disease resulting in end-stage kidney disease. To our knowledge, no research has been conducted to determine the association between Fabry disease, its clinical manifestations, and chronic kidney disease in Durban. Methods This study was a prospective, quantitative study. A cohort of 200 male patients with chronic kidney disease (CKD stage 2-5D) was enrolled. A control group of 14 healthy males was also enrolled for this study. The ELISA technique was employed to determine the alpha Gal-A enzyme concentration levels in plasma. A questionnaire using the MSSI scoring system was presented to the participants to identify clinical manifestations. The SPSS Version 27 (IBM, New York, USA) was used to analyse the data. Results A cut-off value for the alpha Gal-A enzyme concentration levels of < 500pg/ml was calculated. A total of 17 participants from the patient group (n = 11) and the control group (n = 6) displayed alpha-Gal-A enzyme levels < 500pg/ml. The univariate regression analysis revealed, statistically significant association between alpha-Gal levels < 500pg/ml and age (p = 0.007), heat or cold intolerance (p = 0.049), hypertension (p < 0.001) and eGFR (p < 0.001). MSSI scores displayed a negative association (p = 0.001). The multivariate regression analysis showed that age and MSSI scores retained their significance when eGFR was excluded as a variable, however, with the inclusion of eGFR as a variable, none of the variables retained their significance. Conclusion Fabry disease is suspected in 17 participants with alpha-Gal levels of < 500pg/ml. The cause of CKD nephropathy raises interest as conditions such as FSGS have been associated with FD. The low levels of the alpha-Gal enzyme and the presentation of the clinical manifestations can be utilised as preliminary findings. Confirmatory tests such as DNA analysis or Gb3 and GL3 analysis should be performed to confirm the diagnosis.

Authors: Zhuang Bisang , Su Cui , Li Chunwei , Wan Rick , Leung Angela Yee Man , Deng Renli
Published: December 2022

Background: Caregivers of people with dementia experience high stress levels. Network intervention can effectively improve the mental health of caregivers, which is a very feasible way for dementia caregivers who need help.
Objective: The aim was to explore the feasibility and effects of Wechat official account network interventionon family caregivers of people with dementia.
Methods: In a prospective, not-blinded, parallel-group, randomized controlled trial, 116 caregivers of people with dementia were randomized to either the intervention group, receiving Wechat official account network intervention for 3 months; or the control group, receiving the home visits by traditional community workers, telephone follow-up by hospital nurses. Various psychological outcomes of caregivers were assessed and compared at baseline, immediately post-intervention, and at the 3-month follow-up.
Results: There was no significant difference in the level of positive feelings, competence, and care satisfaction between the two groups before intervention (P > 0.05). The intervention group experienced a statistically significant increase in positive feelings levels (T=-3.21, P = 0.001), competence(T=-2.71, P = 0.007) and care satisfaction (T=-3.79, P <0.001) at the post-test. At the 3-month follow-up, the intervention group had a increase in positive feelings levels (T=-4.21, P = 0.000), competence (T=-3.52, P <0.001) and care satisfaction (T=-4.22, P <0.001) compared to the controls.
Conclusion: The findings support the feasibility and effects of Wechat official account network interventionon improving caregivers' positive feelings, competence, and the level of care satisfaction. A future study with a larger and more diverse sample should be developed to evaluate the longer-term effects and generalizability of the Wechat official account network intervention and the impacts on people with dementia.
Residual penile curvature correction by modeling during penile prosthesis implantation in Peyronie’s disease patients
Authors: Hellstrom Wayne , Conlon William , Herzog Bryan
Published: December 2022

With the advent of new surgical techniques to treat Peyronie’s disease with concomitant erectile dysfunction, there remains a question of whether manual modeling, an older technique, still has a place in the treatment algorithm within penile prosthesis surgery. While the implantation of a penile prosthetic often corrects moderate to severe curvature, penile curvature, in some cases, remains greater than 30°. In these cases, manual modeling should be the first line of treatment for persisting intraoperative penile curvature after the placement of a penile prosthetic due to its long-term efficacy, noninvasive approach, and lack of adverse effects.
The Chain Mediating Effects of External Locus of Control and Psychological Entitlement between Parental Over-Protection and Academic Entitlement among Nursing Students: A cross-sectional Study
Authors: Peng Biao , Pang Bing , Lv Mingzhi , Li Hong , Wang Xiuhong , Hu Ningning
Published: December 2022

Background
Academic entitlement in nursing students has been shown to cause problems such as superficial learning, lack of theoretical knowledge, and weak practical abilities, all of which affect the overall quality of nursing talents in the future, thereby affecting the quality of nursing services and patient safet. However, few studies have focused on the academic entitlement of Chinese nursing students and its influencing mechanisms.
Purpose
To explore the influence of parental over-protection on academic entitlement of nursing students, and to examine the mediating roles of external locus of control and psychological entitlement.
Methods
This study employed a cross-sectional, descriptive correlational design. The study sampled two medical universities in Guizhou and Yunnan provinces, China. Participants were nursing students in grades one to four (N = 1,003; mean age = 19.51 years; 81.95% female). Using a structural equation model, we examined the mediating effect of external locus of control and psychological entitlement on parental over-protection and academic entitlement.
Results
Chinese nurses have been shown to have a higher level of academic entitlement than American students. There was a significant correlation between all variables, and external locus of control and psychological entitlement played a chain mediating role between parental over-protection and academic entitlement.
Conclusion
The academic entitlement of nursing students in China demands urgent attention. An over-protective parenting style, an externally controlled attribution style, and psychological entitlement are key factors which lead to nursing students’ academic entitlement. Our findings suggest that academic entitlement of nursing students can be reduced by adjusting parental rearing behaviors, reducing students’ psychological entitlement, and teaching them how to form a healthier attribution style.

Published: December 2022

Background: Cellular senescence refers to cells entering a relatively stable state of cell cycle arrest, which is a barrier that tumor cells must cross to achieve immortalization and plays an extremely important role in preventing the occurrence and development of tumors. In recent years, numerous studies have shown that inducing tumor cells to enter a senescent state has become a feasible tumor control strategy. At present, cellular senescence has become a research hotspot in tumor prevention and treatment, as well as in cell biology. However, the expression and prognostic values of cellular senescence genes in head and neck squamous cell carcinoma (HNSC) remain unclear.
Material/Methods: We analyzed the expression patterns and prognostic values of cellular senescence genes in HNSC from TCGA and GEO. The TCGA-HNSC data wereused as the training group and were divided into high- and low-risk groups, and the GEO database was used as the test group. Analyses included survival analysis, ROC curve analysis, risk curve analysis, independent prognostic analysis and model validation for clinical grouping. We used the HPA database for protein-level validation of the genes.
Results: We identified 5 cellular senescence genes associated with HNSC, namely,BTG3, EHF, EZH2, TACC3 and TXN. These cellular senescence genes were analyzed in the training and test groups and were found to be significantly associated with the prognosis of HNSC patients.
Conclusions: The tumor immune microenvironment of HNSC is closely related to cellular senescence-related features. Cellular senescence genes (BTG3, EHF, EZH2, TACC3, and TXN) have the potential to be diagnostic and prognostic biomarkers for HNSC.
Asset Dependence Prediction Utilizing Spatiotemporal Patterns

Published: December 2022

Financial assets exhibit dependence structures and knowing the dependencies of the assets can help investors to create a diversified portfolio that can reduce portfolio risk due to the high volatility of the financial market. Since asset dependency changes with time in complex patterns, asset dependency forecasting is an important problem in finance. In this paper, we organize pairwise asset dependencies in an Asset DependencyMatrix (ADM ) and formulate the problem of asset dependency fore-cast as the prediction of future ADM s given a sequence of past ADM s.To exploit the spatiotemporal dependencies between the assets, we propose a novel idea that views ADM sequence as an image sequence, where an ADM corresponds to an image and an entry in the ADM to a pixel. This enables us to apply video prediction methods to capture the spatiotemporal dependencies among the assets. In this paper, we propose a novel Asset Dependency Neural Network (ADNN) to tackle the ADM prediction problem. It adopts ConvLSTM, a highly successful method for video prediction, and the novelty of ADNN is the introduction of a transformation function between ADM and ConvLSTM and an end-to-end approach to learn the transformation function. We conducted extensive experiments to evaluate the performance of ADNN and show that our proposed framework consistently outperforms the baselines on future ADM prediction and portfolio risk reduction tasks.
