Authors: Zhang Bin , Xu Zipeng , Gu Weifang , Zhou Junjing , Tang Neng , Zhang Shuo , Chen Chaobo , Zhang Zhongjun
Published: September 2022

Background
Although laparoscopic pancreaticoduodenectomy (LPD) has been accepted worldwide for the treatment of pancreatic ductal adenocarcinoma (PDA), it remains a very technical and challenging procedure. Also, whether LPD is superior to open pancreaticoduodenectomy (OPD) remains unclear. This study summarized the experience and efficacy of LPD to PDA in our medical center from October 2019 and January 2021.
Methods
This retrospective cohort study included patients with PDA admitted at the Affiliated Hospital of Jiangnan University. Patients received either LPD or OPD. Clinical outcomes (operation time, duration of anesthesia, intraoperative hemorrhage), postoperative complications, and short-term outcomes were compared. Cox proportional hazard model and Kaplan-Meier method were used to analyze overall survival (OS) and progression-free survival (PFS).
Results
Among the PDA patients, 97 patients underwent surgical treatment, and 7 of them received conservative treatment. Forty-six patients were cured with LPD, and 1 of them died shortly after the operation. Moreover, 44 patients received OPD, and there were 2 postoperative deaths. There were significant differences in the location of the operation time, duration of anesthesia, postoperative hemorrhage, abdominal infections, and postoperative pneumonia between the two groups (all P < 0.05). Multivariate analysis showed that LPD was an independent factor negatively correlated with the incidence of pneumonia (relative risk (RR) = 0.072, 95%CI: 0.016–0.326, p = 0.001) and abdominal infection (RR = 0.182, 95%CI: 0.047–0.709, p = 0.014). Also, there were no differences in OS (hazard ratio (HR) = 1.46, 95%CI:0.60–3.53, p = 0.40) and PFS (HR = 1.46, 95%CI:0.64–3.32, p = 0.37) at 12 months between the two groups.
Conclusions
LPD is a safe and feasible strategy for managing selected PDA patients. Also, LPD has a better effect on reducing postoperative pneumonia and abdominal infection compared to OPD.
A Metrics-Based Maintainability Estimation Framework for Object Oriented Software in Design Phase
Authors: Macharia Elijah Migwi , Mwangi Waweru , Kimwele Michael
Published: September 2022

Measurement of maintainability early in the software development life cycle, especially during the design phase, may aid designers in incorporating necessary improvements and adjustments to enhance the maintainability of the completed product. In order to demonstrate the importance and necessity of software maintainability during the design phase, this paper expands the (MEMOOD) metrics model, which estimates the maintainability of class diagrams in terms of their understandability and modifiability, to create a multivariate linear model called "Maintainability Estimation Framework and Metrics for Object Oriented Software (MEFOOS)" during the design phase. Thus, class diagrams' maintainability is estimated in terms of theirunderstandability, modifiability, and analyzabilityin the developed model. This study attempts, as a first effort, to create a relationship between object-oriented design features and maintainability elements analyzability, understandability, and modifiability. In spite of this, the study also created three further multivariate models to measure the class diagram's analyzability, understandability, and modifiability. Finally, the presented models have been empirically validated through the use of relevant statistical tests and reasoning from the context
Net Neutrality and Universal Service Obligations
Authors: Gautier Axel , Poudou Jean-Christophe , Roland Michel
Published: September 2022

This paper analyzes whether repealing net neutrality (NN) improves ordecreases the capacity of a regulator to make internet service providers(ISPs) extend broadband coverage through universal service obligations(USOs). We model a two-sided market where a monopolistic ISP links contentproviders (CPs) to end users with a broadband network of a given bandwidth.A regulator determines whether to submit the ISP to NN or to allow it tosupply paid priority (P) services to CPs. She can also impose a broadbandUSO to the ISP, i.e. she can mandate the broadband market coverage. We show that the greater is the network bandwidth, the more likely the repeal of netneutrality increases ISP profits and social welfare. Regulation can still benecessary, however, as there are bandwidth ranges for which the ISP wouldbenefit from a repeal of NN while such a repeal is detrimental to society.

Published: September 2022

Background
Gastrointestinal stromal tumors (GISTs) frequently show KIT mutations, accompanied by overexpression and aberrant localization of mutant KIT (MT-KIT). However, it remains unclear how MT-KIT contributes to GIST pathogenesis.
Methods
To evaluate the expression, localization and stability of wild type KIT (WT-KIT) and MT-KIT, we performed western blotting, biotinylation assays and confocal microscopic analysis using GIST and colon cancer cells. Colocalization of MT-KIT with GRB2, P85, or BLZF1 was examined using immunoprecipitation and confocal microscopy. We screened various WT- and MT-KIT expressing cancer cell lines to identify a regulator of unfolded protein response (UPR) in GISTs. The effect of ATF6 inhibitors were examined in a tetrazolium-based MTT assay and GIST xenograft models. Immunohistochemistry analysis of ATF6 was performed using GIST tissues.
Results
We discovered that MT-KIT initiates downstream signaling in the Golgi complex. BLZF1 was identified as a novel MT-KIT-binding partner that tethers MT-KIT to the Golgi complex. Sustained activation of ATF6, which belongs to the UPR family, alleviates endoplasmic reticulum (ER) stress by upregulating chaperone expression, including HSP90, which assists in MT-KIT folding. BLZF1 knockdown and ATF6 inhibition suppressed both imatinib-sensitive and -resistant GIST in vitro. ATF6 inhibitors further showed potent antitumor effects in GIST xenografts, and the effect was enhanced with ER stress-inducing drugs. ATF6 activation was frequently observed in 67% of patients with GIST (n = 42), and was significantly associated with poorer relapse-free survival (P = .033).
Conclusions
Our findings show that GIST bypasses ER quality control (QC) and ER stress-mediated cell death via UPR activation and uses the QC-free Golgi to initiate signaling.

Published: September 2022

Background

While undescended testes are relatively common, the nonpalpable testis remains a challenging problem. The gold standard treatment remains the laparoscopic orchiopexy. However, today robot-assisted surgery has challenged traditional laparoscopy in many areas of urology. Yet the value of this new approach remains controversial, given concerns with operative time and cost. We reviewed our contemporary results of both robot-assisted orchiopexy (RALO) and traditional laparoscopic orchiopexy (TLO). Our primary aim was to retrospectively compare operative time and cost. We also assessed complications and success rate.

Methods

In this study, all patients treated with laparoscopic and robot-assisted laparoscopic orchiopexy from April 2017 to January 2022 were reviewed using CPT code 54692. Exclusion criteria included bilateral concomitant orchiopexy or concomitant “major surgery.” Also excluded were 1st stage orchiopexies. Patient demographics, surgical operative notes and documentation were all reviewed.

Results

After exclusion criteria was applied, 24 and 22 remained in the laparoscopic and robot-assisted cohorts, respectively. The median operative time in the TLO group was 71 minutes, compared to 102 minutes in the RALO group (Fig. 1) (p > 0.0001). When comparing hospital charges, the TLO group was lower at $38,829, compared to $46,197 in the RALO group (Fig. 2) (p = 0.0069). There was one postoperative complication in the TLO group (localized wound infection), compared to zero in the RALO group.

Conclusions

The robot-assisted orchiopexy is safe and effective. However, at this time it remains more costly in terms of time and resources.

Authors: Furtado Cleofina , Jadun Changrez , Srivast Sachin , Nayak Sanjeev , Hashim Zafar
Published: September 2022

Acute disseminated encephalomyelitis (ADEM) is a central nervous system demyelinating condition caused by viral or bacterial infections or immunizations. The postulated aetiology is an autoimmune reaction against myelin components; however, the mechanistic details are yet unknown. We present the imaging findings of a patient who passed away due to the manifestations of acute disseminated encephalomyelitis. The patient initially underwent surgical repair for type B aortic dissection. 2 weeks after he had poor GCS and no motor response following multiple attempts at sedation hold in the intensive care unit. On magnetic resonance imaging, haemorrhagic white matter abnormalities were noted throughout the cerebral hemisphere indicative of an inflammatory demyelinating process. Our case emphasizes the challenges involved in evaluating emerging neurological problems following a period of intubation /sedation amongst these patients. In addition, unlike children, 50% of adult patients do not have illness or immunisation as a trigger event for this condition.

Published: September 2022

Introduction: Associations of luteinizing hormone (LH) with androgens during the menopausal transition and associations between follicle-stimulating hormone (FSH) levels and various diseases related to reproductive hormones in postmenopause have received much attention. LH and FSH are also known to be associated with activities of enzymes related to reproductive hormones. We examined the associations of LH and FSH with androgens and estrogens in each stage according to a classification from menopausal transition to postmenopause.
Methods: We divided the 173 subjects into 6 groups according to menstrual regularity and follicle-stimulating hormone level: mid reproductive stage (Group A), late reproductive stage (Group B), early menopausal transition (Group C), late menopausal transition (Group D), very early postmenopause (Group E) and early postmenopause (Group F). Levels of LH, FSH, dehydroepiandrosterone sulfate (DHEAS), estradiol, estrone, testosterone (T), free T, androstenedione and androstenediol were measured.
Results: In Group A, LH showed significant positive correlations with androstenedione and estrone. In Group D, LH was positively associated with T and free T and was negatively associated with estradiol. In Groups B, C, D and F, LH showed significant positive correlations with FSH, and there was a tendency for an association between LH and FSH in Group E. FSH was associated with estradiol but not with estrone in Groups C and D.
Conclusion: The associations of LH and FSH with reproductive hormones were different according to the stage of the menopausal transition. The associations between gonadotrophine levels and androgen levels may be important for metabolism from menopausal transition to postmenopause.
Development of Low-Cost Nitrogen and Boron Doped Carbon Black Cathode Catalysts for the Improvement of Hydrogen Bromine Flow Battery Cathode Kinetics
Authors: Duman Büşranur , Fıçıcılar Berker
Published: September 2022

In this study, carbon blacks, containing nitrogen and boron, are used as cathode catalysts first time in a hydrogen-bromine redox flow cell. Nitrogen and boron doping has been applied to carbon blacks to improve the limited properties of the Vulcan XC72 (VXC). Here, we have examined the effect of nitrogen/boron-doped Vulcan XC72 carbon black on hydrogen-bromine flow cell performance. Nitrogen gas and boric acid are used as nitrogen and boron sources in the post-doping process, respectively. XRD, SEM, XPS, Raman spectroscopy, and N2 adsorption analyses are used to characterize the structures of cathode catalysts. The electrochemical characterization of the catalysts has been carried out with the cyclic voltammetry technique using the conventional three-electrode system connected to a potentiostat. We have addressed the effect of nitrogen and boron doping into the carbon black onto the flow battery performance by comparing their polarization and power curves. The maximum power densities with the VXC, N-VXC, and B-VXC cathode catalysts have been measured at 0.75V as 360, 390, and 430 mW/cm2, respectively.

Published: September 2022

Background: The purpose of this study was to compare the Tuition-Free and Paid Medical and Dental Students in terms of assessment based on multiple-choice test statistics.
Methods: This descriptive-analytical study was conducted at Golestan University of Medical Sciences in Iran in 2020. The study population included students of medicine and dentistry. A total of 56 exams were selected in two student groups of free and tuition-paying admission in the physiology course. The results of quantitative evaluation of tests were used as the data of this study. The variables included difficulty index, discrimination index, the degree of difficulty, score variance, and Kuder-Richardson correlation coefficient.
Results: There were 32 medical and 24 dentistry exams. The cumulative total number of questions in these exams was 437 and 330 multiple choice questions, respectively. The number of medical students participating in the free-tuition and paying-tuition admissions was 1336 and 1076, and for dental students, these numbers were 395 and 235, respectively. There were no significant differences in normalized adjusted exams scores between two admission groups in both medical and dentistry tests. The mean of discrimination index in the free-tuition group was higher than in the paying-tuition group. The interaction between the type of admission and the field of study was significant for the discrimination index. This difference was more in tuition-free dental students than tuition-free medical students and tuition-paying dental students.
Conclusion: The type of student admission has no significant effect on student assessments in multiple-choice exams in matched educational conditions.

Relationship between Maslow’s hierarchy of needs and mumpreneurial intentions
Authors: Abdelsalam Rasha , Al-Haddad Shafig , Ahmad Sharabati Abdel-Aziz
Published: September 2022

Nascent mumpreneur is a mother with one or more children coming up with a new venture to support herself and her family. The debate about the motivation for mumpreneurs to start their new business is going on and underresearched. Therefore, this study aims to define the major motivational factors that influence mumpreneurial intentions in Jordan, specifically amongst nascent mumpreneurs. Maslow’s hierarchy of needs was employed to discover these factors. This quantitative cross-sectional study uses convenience sampling to collect data from 81 nascent mumpreneurs through an online survey that included nascent Jordanian mumpreneurs. After confirming the validity and reliability of the tool, the multiple regressions test was used to test the hypotheses. The results indicate a strong relationship between Maslow’s needs and mumpreneurial intentions, where r equals 0.74, and Maslow’s needs can explain 54% of changes in mumpreneurial intentions, where R2 is 0.54. The results also show that the need for esteem influences mumpreneurs’ intentions (β = 0.43), and the need for self-actualization influences mumpreneurs’ intentions (β = 0.80). At the same time, the physiological needs, the security needs, and the need for belonging do not influence mumpreneurial intentions, where significance is 0.74, 0.09, and 0.09, respectively. Moreover, the results show that the marital status and level of education do not moderate the influence of Maslow’s theory of needs on mumpreneurs’ intentions, where the significance for both is more than 0.05. Finally, the study recommends developing mumpreneurial incubators and providing workshops and training for potential mumpreneurs.
Social and personal control, legitimacy of authorities, and social cohesion as protective factors of anti-sociality in adolescents
Authors: Frías Armenta Martha , Corral Frías Nadia Sarai , Serrano Arias Martha Esther
Published: September 2022

Law can shape individual and social behavior in different ways including through perceived control and legitimacy of authorities. The primary aim of this study was to investigate whether legitimacy of authorities, social and personal control, and social cohesion influence antisocial behaviors in juvenile offenders. The study, included a sample of two hundred juvenile offenders in Mexico, used structural equation modeling to test the relationship between the perception of just treatment by police and judges (i.e., legitimacy) and social and personal control and outcomes of antisocial behaviors and tendencies (self-report and probability of antisocial behavior as well as reports of peer antisocial behavior). Results indicate legitimacy of authorities and personal control had a negative effect while social control showed a positive effect on these behaviors. Social cohesion had a positive effect on social control. Our results suggest that legitimacy of authorities and personal control act as protective factors against antisocial behaviors whereas, contrary to the expected results, social control may be a risk factor. This research highlights the importance of preventative protective efforts in juvenile offenders such as just treatment and development of personal control rather than the use of punitive processes. In this sense, it is important to consider alternatives for judicial involvement and punishment such as community programs as well as cognitive and emotional prevention and intervention efforts to reduce antisocial behaviors. Programs such as the Reasoning and Rehabilitation Program, other cognitive skill interventions as well as developmental prevention programs have shown efficacy.
Recent Advances in the Development of Oxytocin Receptor Antagonists
Authors: Williams P. D. , Pettibone D. J.
Published: September 2022

During the last decade there has been significant progress in the design and discovery of new structural classes of oxytocin antagonists. Continued study of oxytocin analogs has led to the design of antagonists. The similar topography of important functionalities in peptide and non-peptide oxytocin antagonists suggest the possibility of a common pharmacophore. New modifications to the classical antagonist analogs of oxytocin have provided analogs with significant improvements in potency, dura-
tion of action, oxytocin receptor selectivity, and bioavailability by non-parenteral routes of administration. In addition, optimization within two structural classes of non-peptides has provided potent and selective analogs which offer the potential for obtaining a clinically useful, orally bioavailable oxytocin antagonist. Human clinical studies with the peptidic oxytocin antagonist, atosiban, have implicated oxytocin as a potential contributor to the pathophysiology of preterm labor and suggests that oxytocin receptor blockade may offer a useful new method for preventing premature birth.
Targeting Transcription through Nuclear Receptors
Authors: Jones Barbara B. , Petkovich Martin
Published: September 2022

It has long been known that the structural modification of steroid hormones can alter their biological activity. Some of these changes in activity are attributable to altered uptake and metabolism. With the cDNA cloning and characterization of nuclear receptors for steroids and related compounds, it has become possible to ascribe changes in ligand activity to specific alterations in receptor function. In this review we will discuss the steroid/thyroid hormone receptor superfamily, and how knowledge of receptor structures and mechanism of action may be exploited therapeutically to alter their effects
on gene expression in human disease states. We will discuss the basic structure of nuclear receptors and possible mechanisms by which their activities can be altered by ligands, both natural and synthetic. Later, we will focus on specific investigations related to the mechanism of action of some of the more widely studied antagonists. Finally we will examine the use of synthetic ligands and look at how determination of detailed receptor structures may help us to design more highly specific and effective ligands.
La institucionalización del sistema de partidos en el Perú, durante los años 2016-2021
Authors: Ángeles D. , Cabrera M. , Risco N.
Published: September 2022

Within a democratic State, the party system and its degree of institutionalization influence the governability and stability of a country. In the Peruvian case, there is a constant crisis of representativeness towards the current political parties, directly affecting the institutional level. Therefore, this reality is problematized through the following question: What factors influenced the process of institutionalization of the Peruvian party system during the years 2016 - 2021? This article seeks to respond to this based on the analysis of two political phenomena: "electoral volatility" and "political identity", describing these variables from the institutional and social levels, in order to argue the low institutionalization of the Peruvian party system.

¡A limpiar agua con óxidos! Química de materiales al servicio del medio ambiente
Authors: Martínez García Ana Luisa , Montiel González Zeuz , Ramírez Esquivel Obed Yamín , Mazón Montijo Dalia Alejandra
Published: September 2022

En este artículo se aborda un tema de interés global: la descontaminación del agua a través de la acción de fotocatalizadores. Actualmente, existen contaminantes persistentes en casi todos los recursos hídricos del mundo que no pueden limpiarse con tratamientos convencionales, principalmente debido a su alta estabilidad química. Por ello, se recurre a procesos avanzados tales como la fotocatálisis, donde un material conocido como fotocatalizador es el actor principal. Sin embargo, los procesos fotocatalíticos aún están lejos de alcanzar su máxima eficiencia, por lo que la búsqueda de métodos alternativos para el mejoramiento del desempeño es una preocupación vigente, sobre todo considerando el aprovechamiento de la luz del Sol y en la forma en que se ponen en contacto el fotocatalizador y el agua contaminada. Con la ayuda de la química de materiales, te contamos cómo es que capas delgadas de unos óxidos tan comunes el óxido de hierro y óxido de zinc podrían funcionar como un fotocatalizador con alto potencial para descontaminar el agua de una manera más eficiente y con el menor impacto al ambiente.

The Improvement of Balance, Coordination & Proprioception Following an MPI Cervico-Thoracic Junction Seated Adjustment: A Case Report
Authors: Williams Dr. Brogan , Woodbury Dr. Michael
Published: September 2022

Abstract: Further enquiries into how spinal manipulation directly impacts proprioception, balance and coordination are required to support the current body of evidence. The leading question of this study was “Does a Motion Palpation Institute cervico-thoracic junction high velocity, low amplitude adjustment impact proprioception, balance and coordination?”. A 32- year-old female with no prior gymnastic experience was recruited for this case-study. The participant was blind folded and given two attempts to maintain a static tandem Romberg stance on a 46cm high, 20cm wide gymnastic balancing beam for as long as possible. During the first attempt the participant lost her balance immediately. The participant then received a seated Motion Palpation Institute cervico-thoracic junction adjustment. Following the adjustment, an immediate improvement in balance, proprioception and coordination was observed. During attempt two, the participant could maintain her balance exponentially. The findings of this study suggest that spinal manipulation may have a potential benefit on proprioception, balance and coordination in a healthy patient. This further illustrates the importance of spinal manipulation as a non-invasive, low cost and low risk treatment. Further research to expand the findings of this study are needed to reach a stronger conclusion.
Tight constraints on probabilistic convertibility of quantum states
Authors: Regula Bartosz
Published: September 2022

We develop two general approaches to characterising the manipulation of quantum states by means of probabilistic protocols constrained by the limitations of some quantum resource theory. First, we give a general necessary condition for the existence of a physical transformation between quantum states, obtained using a recently introduced resource monotone based on the Hilbert projective metric. In all affine quantum resource theories (e.g. coherence, asymmetry, imaginarity) as well as in entanglement distillation, we show that the monotone provides a necessary and sufficient condition for one-shot resource convertibility under resource-non-generating operations, and hence no better restrictions on all probabilistic protocols are possible. We use the monotone to establish improved bounds on the performance of both one-shot and many-copy probabilistic resource distillation protocols. Complementing this approach, we introduce a general method for bounding achievable probabilities in resource transformations under resource-non-generating maps through a family of convex optimisation problems. We show it to tightly characterise single-shot probabilistic distillation in broad types of resource theories, allowing an exact analysis of the trade-offs between the probabilities and errors in distilling maximally resourceful states. We demonstrate the usefulness of both of our approaches in the study of quantum entanglement distillation.
Emancipações comunicativas, políticas e estéticas na articulação de corporeidades negras em torno do movimento secundarista
Authors: Altheman Francine , Marques Ângela
Published: September 2022

Este artigo é uma reflexão sobre as potencialidades estéticas dos arranjos disposicionais que constituem as cenas de insurgência do movimento secundarista, que ocupou as ruas e as escolas de São Paulo em 2015. A proposta envolve pensar sobre a fabulação estética do movimento a partir das transformações de si das corporeidades negras, por meio de suas narrativas e de suas produções artísticas. Essas reflexões partem do diálogo entre Foucault, Rancière e Deleuze sobre a formação do sujeito político nas resistências. O texto aposta em uma potencialidade da experiência estética para a emancipação política do sujeito, bem como a potência de corporeidades negras em processos comunicacionais de questionamento de imagens de controle. Ele aponta ainda para a construção da cena insurgente por meio dos arranjos disposicionais que ela provoca, atentando também para asvulnerabilidades e interseccionalidades dos sujeitos envolvidos.

Angola no Atlântico Sul
Authors: Xavier Schütz Nathaly Silva
Published: September 2022

Angola, depois do encerramento da Guerra Civil em 2002, ascende como um importante polo de poder no Continente Africano. Nesse contexto, o Atlântico Sul apresenta-se como um importante ambiente de interação regional e global. Da mesma forma, a Comunidade dos Países de Língua Portuguesa (CPLP) é um fórum de cooperação regional que tem no mar um dos seus fatores de aglutinação. Apesar disso, Angola não atua com protagonismo na Comunidade. A questão que norteia essa pesquisa é como a participação de Angola na CPLP pode ser um instrumento de sua projeção regional. Parte-se do pressuposto que as dificuldades de Angola de estruturar uma política marítima impactam negativamente no seu papel dentro da Comunidade. O objetivo geral do artigo é analisar a política externa de Angola pós-Guerra Civil, em especial nas questões do Atlântico Sul e da participação na CPLP, no tocante a sua projeção regional. A pesquisa é qualitativa, com método hipotético-dedutivo, com abordagem histórica e comparativa; para tanto, será empregada pesquisa bibliográfica e documental. Conclui-se que as falhas na política angolana e as dificuldades institucionais da CPLP dificultam a participação de Angola na Comunidade.
What are the conditions to become smart?
Authors: Csukás Máté , Zs. Szabó Roland
Published: September 2022

Smart cities (SCs) became a key mission in the European Union’s biggest research programme (Horizon Europe). The urban transition to smartness, making smart decisions and strengthening capabilities for resilience are appreciating today, with such external shocks as the COVID-19 pandemic. Finding the way to become smart is more important than ever. Since literature is mostly engaged with excellent cases, in this paper we analyse the SC strategy of a less-well-performing city: Budapest in Hungary, Central Eastern Europe, using a case-study methodology. We reveal that in the case of Budapest the SC strategy uses a top-down approach that overweighs the deployment of technological solutions to manage urban sustainability issues rather than using a bottom-up and holistic approach. The framework conditions for implementing the SC strategy are rather neglected. In the case of the model for cooperation, Budapest adopts a double-helix model rather than a triple- or quadruple-helix model.
