Published: November 2023

Bonding between metal components and denture base resin plays an important role in the success of removable partial denture. Removable partial denture prostheses often present a mechanical failure. The bonding between metal framework and acrylic resin is usually a mechanical interlock, since they do no t chemical bond spontaneously. The aim of this study was to evaluate the effect of different surface treatments (diazonium salt and aluminum oxide) on the shear bond strength of PMMA at the Co/Cr and titanium alloys interface. Sixty-disc shape specimens were prepared and divided into 2 main groups according to the type of material, 30 specimens for C o/Cr alloy and 30 specimens for titanium alloy, then subdivided into 3 groups each one consist of 10 specimens, accordi ng to type of surface treatments. Each group had control group, aluminum oxide group (110 μm), and diazonium salt g roup. The specimens were thermocycled (3000 cycles) after applications of PMMA. Shear bond strength test conduc ted with crosshead speed 0.5mm/min. Data analyzed via One-way ANOVA and GHD test. Co/Cr alloy revealed that diazonium salt surface treatment had highest mean value of shear bond strength followed by aluminum oxide surface treatment at p<0.01. For titanium alloy, the results showed the diazonium salt surface treatment had highest mean value of shear bond strength followed by aluminum oxide surface treatment group at p<0.01. Aluminum oxide treatment slightly increased shear bond strength for both C o/Cr and titanium, while diazonium salt treatment statistically increased shear bond strength for Co/Cr and titanium alloy.

Published: November 2023

The Kentucky Re-entry Universal Payload System (KRUPS) is a small spacecraft developed to provide flight data during atmospheric reentry. The KRUPS capsules made a historic reentry into the Earth’s atmosphere in 2021, and this work details the reconstruction of the flight trajectories by inverse estimation based on the flight data. A trajectory modeling program is used with a one-dimensional material response solver to generate a prediction of the stagnation wall temperature of the KRUPS capsule during of the KRUPS capsule during reentry. These temperature results are compared to the temperature data obtained during the mission, and the initial parameters of the trajectory simulation are optimized to find the best estimated trajectories. The inverse estimation is performed in three ways: by assuming radiative equilibrium at the wall, by estimating the wall temperature after the trajectory simulations are first performed, and by coupling the trajectory and one-dimensional material response solver. Finally, the best estimated trajectories are compared against simulations performed using a three-dimensional material response solver, the Kentucky Aerodynamics and Thermal-response System Fluid Material Response module. It is observed that all approaches converge to a possible ejection of the KRUPS capsule into the Earth’s atmosphere at 35 km.

Empowering Educators: Addressing Drug Abuse Among Students in Technical and Vocational Education and Training (TVET) Colleges
Authors: Ezomo Olawunmi D , Prinsloo Carine
Published: November 2023

The issue of drug abuse has emerged as a significant public health concern, not only globally but particularly in South Africa. This study focuses on the context of Technical and Vocational Education and Training (TVET) colleges, which have unique challenges related to drug abuse among students. The study seeks to explore the essential training required for educators who play a crucial role in managing students struggling with drug abuse. The article delves into the specific knowledge and skills necessary to empower educators in addressing the complex issue of student drug abuse.

The purpose of this study was to explore the training requirements for educators in effectively managing drug-abusing students in TVET colleges. The study employed a non-experimental quantitative exploratory descriptive design. The target population consisted of educators from specific TVET colleges in South Africa’s Limpopo Province. A census sampling approach was used to survey the entire population of 337 educators. Data were collected using a structured, self-administered web-based questionnaire, and the response rate was 55.1%.

The study found that educators strongly associated specific behaviours with suspected drug abuse among students, allowing for early identification. However, there was considerable variability in educators’ responses on how to manage students suspected of drug abuse. A substantial portion of educators had not received training on managing students abusing drugs. The study revealed varying perspectives among educators regarding the importance of educator-student relationships. This study sheds light on the need for comprehensive training for educators in addressing student drug abuse issues in TVET colleges. It emphasises the role of educators in early identification and effective management. The findings provide a foundation for future research and interventions in this critical area, not only in South Africa but also in similar educational settings globally.
Open Access Scholarly Book Publishers in South Africa: The Search for a Generic Business Model—or Two
Authors: Pieterse Hetta C
Published: November 2023

This article is based on a master’s dissertation proposing a generic business model following a study of seven open access (OA) scholarly book publishers in South Africa. A qualitative research methodology was used, with pre-populated questionnaires and semi-structured interviews. The author discusses business models in use at seven local publishers. After comparing customer segments, relationships, partnerships, key activities, resources, channels, value propositions, and revenue streams, two possible scenarios for ideal business models emerge. The first scenario is that of a non-profit dedicated OA publisher doing community service and with dedicated OA funds. The second scenario is that of an OA book publisher with cross-subsidising business streams
DIGITAL EVIDENCE IN INTERNATIONAL CRIMINAL PROCEEDINGS AND HUMAN RIGHTS CHALLENGES
Authors: Ragni Chiara
Published: November 2023

Digital technologies offer great opportunities in every field of life, including in criminal proceedings, where gathering evidence using digital or computer devices is an important contribution to the investigation of crimes, especially at the international level. Digital evidence is particularly important in the prosecution of international crimes due both to their complexity and to its ability to overcome hurdles that international judges must overcome when factfinding relates to conduct that occurred far from the seat of the court. While the of digital evidence is increasing, however, questions have arisen concerning both its admissibility and of its reliability, as the jurisprudence of the International Criminal Court (ICC) and other international criminal tribunals makes clear. The use of digital evidence may also raise concerns for the respect of due process standards and the right to private life. In the absence of specific international legal rules that deal with the matter, the purpose of this contribution is to identify the most pressing issues through an examination of the case law of international tribunals and to infer potential solutions and best practices to consider in developing international human rights based procedural standards.
MANAGING CROSS-BORDER “DIGITAL SUCCESSION” IN THE DIGITAL ERA : PRELIMINARY REMARKS ON THE NEW CHALLENGES FOR THE CURRENT LEGAL FRAMEWORK
Authors: Viarengo Ilaria , Re Jacopo
Published: November 2023

This paper aims to answer to a rather common question: what happen to our digital estate when we die? To do so, after analysing the composition of a digital estate, the paper will determine, firstly, the legal framework applicable to a cross-border succession to a digital estate. It will then investigate: (i) which assets are transferable upon death and to what extent; (ii) under what conditions heirs have access to the deceased’s accounts; and (iii) which interests on the digital content created by the deceased are protected and how. The analysis will be conducted through the lens of the current private international law framework in force in EU Member States, in order to formulate some preliminary remarks on its adequacy to manage this new succession phenomenon and the issues it raises.
DATA PROTECTION AND CYBERSECURITY : CASE-LAW OF TWO EUROPEAN COURTS
Authors: Duić Dunja , Petrašević Tunjica
Published: November 2023

Cybersecurity is not easily defined. The 2019 EU Cybersecurity Act defines it as the activities necessary to protect network and information systems, the users of such systems, and other persons affected by cyber threats. Enduringly, cybersecurity was associated with national security, without consideration of what ‘secure’ Internet means for individual users. In reality, cybersecurity policy focused by and large on systems rather than users, i.e., people. However, as a policy area concerned with online behavior regulation, its definition and implementation inevitably has profound implications for human rights, especially in regard to data protection and freedom of expression. Unsurprisingly, cybersecurity has become a new human rights battleground. The EU Cybersecurity Act and subsequent legislation represent a normative shift in our conception of data ownership, putting ownership and control of personal information in the hands of the user rather than the service provider. Luckily, there have been positive legislative shifts regarding data protection in the context of the EU cybersecurity policy at EU level. But are they (or will they be) adopted by European courts? To answer, this paper peers into the relevant case-law of the Court of Justice of the EU as well as of the European Court of Human Rights.
TOUCH SCREEN JUSTICE AND CONSUMER VULNERABILITY – A MIXED BLESSING?
Authors: Poretti Paula
Published: November 2023

Digitalization is the future and the future is now. New commercial possibilities in the digital market are constantly being explored and exploited. Phenomena such as ecommerce automation and the impact of big data use on transformation of retailer-consumer relationship are increasingly present and more familiar by the day. With them, new perspectives to render consumers vulnerable arise. The digital vulnerability, unlike other types of consumer vulnerability is a state typical of every consumer in the digital market. This notion challenges the existing consumer law and policy’s ability to address the issues that arise in relation to such vulnerability with the traditional perspective. It also questions whether the redesign in the architecture of digital marketplaces is making the traditional architecture of dispute resolution obsolete. With these issues as a starting point, the paper assesses the current trend of streamlining consumer dispute resolution to AI tools and touch screen justice. We argue that under the current set up, instead of providing access to justice that is more available to consumers, this trend has a potential to generate a systemic vulnerability in itself.
CONTEMPORARY FORMS OF WORK WITH A DIGITAL FEATURE IN PRIVATE INTERNATIONAL LAW
Authors: Golub Jura
Published: November 2023

Digitalization has enabled the rapid development of the gig economy and changed the entire paradigm in such a way that through digitalization people are increasingly achieving their primary employment. As a result, there is a frequent occurrence of the phenomenon of digital nomads and platform workers. Although initially conceived as freelance jobs, in certain cases, the legal relationships of digital nomads or platform workers take on the characteristics of an employment relationship. To circumvent fiscal and labour obligations, digital nomads or platform workers are often defined in contracts as self-employed individuals or independent contractors, resulting in a deprivation of labour rights. Consequently, a challenge arises for European private international law in terms of the correct characterization regarding the legal relationship and, subsequently, the application of the appropriate conflict of law rule to determine the applicable law.

Authors: Kučina Softić Sandra , Čičko Tea , Kvočić Petra , Radobolja Tona
Published: November 2023

Modernising law and legal education are inevitable in today’s society. Possible arguments for not taking such steps disappeared with the pandemic which fostered processes which were postponed or were found as not applicable. Onwards, the COVID-19 pandemic has further accelerated the existing trend toward online and hybrid learning. It uncovered new and innovative ways for students and educators to organise their teaching and learning activities and to interact in a more personal and flexible manner online. Several papers and policies on the European level, among them Digital Education Action Plan highlight the importance of developing a high-performing digital education ecosystem and higher levels of digital capacity of education and training systems and institutions. Still, the process of modernisation and digitalisation of law and legal education is complex and requires significant efforts and resources from all stakeholders involved. The important aspect in this process is teachers’ preparedness and ability to implement digital technologies in teaching and learning, the support they need in this process as well as their training in digital skills to be able to properly use and implement digital technologies using new teaching methods and digital pedagogies. This paper discusses how to support teachers in the digitalisation of law and legal education and teachers’ training in acquiring necessary digital competences. This is part of the Erasmus+ project Digital in Law Education (DIGinLaw) where one of the results is the development of 12 MOOCs on the topic of law and legal education in higher education. The aim of this paper is to reveal the significance of organizational support for teachers and the importance of developing teachers’ digital skills and competences for successfully meeting the challenges of the digitalization of legal education. The paper describes the process taken to support teachers in the development of MOOCs including their training in digital skills. The results of the research – the proposed model of supporting and training teachers in MOOC design - can be applied to similar requirements for higher education teachers’ support in implementing digital technologies in teaching and learning. Using the survey as a quantitative research method and in-depth semi-structured interviews as a qualitative method, the paper gives insight into teachers’ readiness to use digital technologies and what kind of support and training they need to sufficiently implement digital technologies in the educational process.

Published: November 2023

The nasoalveolar molding (NAM) appliance has been the appliance of choice for pre-surgical orthopedics to improve nasal and lip morphology, and optimally align the alveolar segments before cheiloplasty. However, the appliance has some limitations, including its complexity and long clinical chair time for appliance adjustments. In this case report, we present a patient treated for a right complete cleft lip and palate using three types of Korat modification for NAM with a 5-year follow-up. This study demonstrated that the Korat-NAM improved the aforementioned issues and was suitable for patients at different stages before and after lip and palate repair.

Published: November 2023

Background:

Despite the proven benefits of lumboperitoneal shunt (LPS) for idiopathic normal-pressure hydrocephalus, complications such as catheter migration remain a problem. Inguinal complications of the distal catheter are rare in adults, and their management is uncertain. Herein, we present two cases of distal catheter migration into the inguinal hernia sac after LPS in adults and recommend their management.

Case Description:

An 86-year-old man presented with inguinal swelling. In another 82-year-old man who did not show any improvement after LPS, shunt angiography revealed LPS dysfunction due to lumbar catheter occlusion and distal LPS catheter in the right inguinal hernia sac, and lumbar catheter reconstruction was performed. Both patients did not have any symptoms, except inguinal swelling, and were followed up. After 2 weeks and 4 days, the distal catheter moved into the peritoneal cavity.

Conclusion:

Inguinal complications due to the migration of the distal catheter into the inguinal hernia sac are rare in LPS because frequent movements of the distal catheter due to trunk rotation dislodge it from the inguinal hernia sac for a short period. Urgent surgery was not recommended because the catheter was moved in a short period and the patients did not wish to undergo hernia repair.

Authors: Colamaria Antonio , Leone Augusto , Fochi Nicola Pio , Di Napoli Veronica , Giordano Guido , Landriscina Matteo , Patel Kashyap , Carbone Francesco
Published: November 2023

Background:

This review focuses on the recently published evidence on tumor treating fields (TTFields) administered alone or in combination with locoregional and systemic options for treating glioblastoma (GBM) in the past ten years. The aim is to critically summarize the novelty and results obtained with this innovative tool, which is becoming part of the armamentarium of neurosurgeons and neuro-oncologists.

Methods:

A comprehensive search and analysis were conducted on pivotal studies published in the past ten years. Furthermore, all completed clinical trials, whose results were published on clinicaltrials.gov, were examined and included in the present review, encompassing both recurrent (r) and newly diagnosed (n) GBM. Finally, an additional examination of the ongoing clinical trials was also conducted.

Results:

Recent trials have shown promising results both in patients with nGBM and rGBM/progressive (rGBM), leading to Food and Drug Administration approval in selected patients and the Congress of Neurological Surgeons to include TTFields into current guidelines on the management of GBM (P100034/S001-029). Recently, different randomized trials have demonstrated promising results of TTFields in combination with standard treatment of n- and rGBM, especially when considering progression-free and overall survival, maintaining a low rate of mild to moderate adverse events.

Conclusion:

Optimal outcomes were obtained in nGBM and progressive disease. A possible future refinement of TTFields could significantly impact the treatment of rGBM and the actual standard of care for GBM, given the better safety profile and survival effects.

Published: November 2023

Background:

Craniovertebral junction (CVJ) pathologies include atlantoaxial instability/deformities resulting in myelopathy, respiratory failure, and even death. Here, we describe the indications, preoperative planning, and intra-operative/postoperative complications following surgical management of CVJ anomalies.

Methods:

A prospective analysis of 34 patients with CVJ pathology was evaluated between 2015 and 2022. Their various etiologies included atlantoaxial instability, trauma, tuberculosis, Down’s syndrome, Morquio syndrome, os odontoideum, and atlantoaxial abnormalities. Clinical outcomes were assessed using the American spinal injury association (ASIA) impairment scale score and Benzel’s modified Japanese Orthopedic Association (mJOA) score. Surgical assessments included length of hospital stay, operative time, blood loss, and intraoperative postoperative complications. Radiological parameters included fusion (i.e., implant loosening/implant failure), preoperative/ postoperative atlanto-dens interval (ADI), clivus canal angle (CCA), and space available for cord (SAC).

Results:

Five patients were managed conservatively, while 29 patients had surgery. Operations included occipitocervical fusion (14 patients), C1–2 fusion (10 patients), C1–2 transarticular screw fixation (four patients), and one patient underwent anterior corpectomy decompression/fusion. Seven patients had vertebral artery anomalies, and 13 patients had atlantoaxial abnormalities. At the final follow-up, atlantoaxial instability (i.e., mean preoperative ADI of 6.6 ± 2.3 mm) was restored to 4.2 ± 0.6 mm, significant cord compression (i.e., with mean SAC of 8.3 ± 2.9 mm) was relieved to 17.2 ± 1.6 mm, and the mean preoperative CCA (i.e., 130.2 ± 15.3) was improved to 143.3 ± 8.3°. There was also a statistically significant improvement in the ASIA scale and mJOA score.

Conclusion:

Surgical management of CVJ abnormalities requires expertise and meticulous planning to avoid devastating complications such as wound dehiscence and catastrophic vertebral artery injury.
Evaluation of dyeing properties of Eclipta Alba L. on protein yarn and their chemical analysis
Authors: Gogoi Minti , Baruah Bulbul , Buragohain Pori
Published: November 2023

Dyes are colored substances used to color fibers, leather, paper or foodstuffs etc. Due to the benign nature of dye extracted from natural sources, more importance is given on this area. Natural dyes also protect us from harmful UV rays of the sun and also provide superior quality sensory feelings in contrast to the carcinogenic effect of synthetic dyes. In this study, natural dyes present in the Eclipta alba L(Hassk) were extracted using conventional techniques under different operating conditions. Potential of the chemicals obtained from the extracts of Eclipta alba. L. was evaluated by coloring pure yarn of silk and wool. Various metal salts were used as mordants to set extracted dye on the fabrics and yarns. The result showed a variation of attractive and earthly green hue on silk and wool. The phyto chemical analysis of the extract reveals that three chemical compounds wedelolactone, apigenin and luteolin are mainly responsible for different shades of bluish green colour extract of the Eclipta alba plant. Spectrochemical analysis was done to identify the compounds present in the dye extract.

Authors: Tamil Elakkiya G. , Chandrasekhar R. , Sundararajan G.
Published: November 2023

Watermelon rind aqueous extract mediated synthesis of CdS nanoparticles was investigated for its efficiency towards removal of lead and cadmium ions from aqueous solutions. Batch adsorption investigations were performed to optimise the experimental conditions. The optimised conditions were found to be pH 6, 1 g L-1, 30 min and 303 K respectively for the removal of lead and cadmium ions. The equilibrium data obtained was analysed with isotherm models and it was found that Langmuir and Freundlich isothersm explain better and the loading capacities were found to be 332.2 and 318.7 mg L-1 respectively for Pb2+ ad Cd2+ ions. Kinetic investigations suggest that pseudo second order kinetic model fits well to the experimental data suggesting that chemical reactions govern the rate limiting step. The spontaneous and exothermic nature of the present process was successfully demonstrated by the thermodynamic investigations. Desorption and regeneration studies suggest that the CdS nanoparticles can be successfully regenerated 5 times and reused in the adsorption process.

In order to achieve the purpose of this study, data was obtained from restaurant consumers who had experienced influencers' advertisements on social media by adopting a judgment sampling technique. Both online- and paper-based surveys were conducted simultaneously, and the online-based questionnaire was developed using Google Docs. Among 236 participants, 224 valid copies were used for the hypotheses test. The findings of this study are as follows. First, social, functional, and hedonic values positively and significantly affect influencer trust, while social and functional values positively and significantly affect purchase intention. Second, influencer and product trust have positive and significant effects on purchase intention. Third, social, hedonic, and functional values positively and significantly affect purchase intention. These findings are essential for restaurant companies to understand the consumption value of restaurant consumers who use social media and provide implications for developing effective marketing strategies that can increase trust and purchase intention by utilizing the influence of social media influencers.
A study on the influence of brand image on purchase intention and word-of-mouth intention of return gift from hometown donation system: focused on Jeollabuk-do province
Authors:   The Table and Food Coordinate Society of Korea, Cho Won-Young , Kang Gee-Il
Published: November 2023

This study examines the relationship between the brand image, purchase intention, and Word-of-Mouth intention of the return gift of the Hometown donation system in Jeollabuk-do, the most active place in the agricultural economy. As a result, among the brand images in the return of the Hometown donation system, the image of the donation area, the quality of the return gift, and the image of the product had a statistically significant and positive effect on the purchase intention and Word-of-Mouth intention. However, the effect of brand recognition was not significant. Thus, even if community donations are meaningful, it can be concluded that the quality of the product is the most crucial factor in increasing the purchase intention of the return gift, and the image of the donation area is the most critical factor in increasing the word-of-mouth intention. The implication for this is that, first, the quality of return gifts for the Hometown donation system is the most stimulating factor, so companies that manufacture return gifts should consider improving product quality. Second, the image of the donation area affects the donor's Word-of-Mouth intention. In addition, special legal restrictions are needed to prevent overheated competition among local governments for return gifts, and a method of setting the limit on it as a certain percentage of the donation amount can be used. Finally, both tangible and intangible products such as local tourism facilities or festivals and various cultural experience products can also return gifts.

The new threaded species were characterized by 1D and 2D NMR spectroscopy as well as by X-ray crystallography for one of them. The BODIPYs exhibited interesting fluorescence features with quantum yields up to 91% and enhanced photostability compared to their non-threaded homologues.
Prediction of phase composition and process resilience in plasma-assisted hetero-aggregate synthesis using a machine-learning model with multivariate output
Authors: Lu Yuanqing , Fazletdinov Timur , Pan Zhiwen , Wondraczek Katrin , Wondraczek Lothar
Published: November 2023

The synthesis of nanoscale particles and particle aggregates from liquid or gaseous precursors is affected by a variety of trade-off relations, for example, in terms of product composition, yield, or energy efficiency. Machine-supported process evaluation and learning (ML) of these relations enables optimization strategies for advanced material processing. We demonstrate such a workflow on the example of plasma-assisted aerosol deposition (PAAD) of alumina powders. Depending on processing conditions, these powders comprise of hetero-aggregate mixtures of crystalline and amorphous polymorphs. Process optimization towards a specific target composition calls for ML approaches. For this, a sufficiently large and consistent dataset of PAAD input (processing) and output (product) parameters was initially generated by real-world processing, and subsequently extrapolated into a cloud of ~ 106 input-output parameter matrices using Gaussian process regression with multivariate output and input-output feature analysis. We subsequently demonstrate how not only the phase composition of obtained alumina powders, but also product resilience to variations in specific processing parameters, or - as a perspective - the energy efficiency of material processing can be predicted.

Published: November 2023

The development of p-n tandem dye-sensitized solar cells (t-DSCs) offer the potential for substantial open-circuit voltages, holding great promise for a wide range of applications, particularly in the fields of photovoltaics and photoelectrochemical devices. Most reported t-DSCs are liquid-based, which suffer from unsatisfied stability due to the leakage of liquid electrolytes and photovoltage that is limited to the energy difference of the two utilized semiconductors. In this study, we present the first realization of a solid-state p-n tandem dye-sensitized solar cell that incorporates both p-type and n-type solid-state dye-sensitized solar cells (ssDSCs) in a series configuration, introducing a transparent back contact indium-doped tin oxide (ITO) for both sides. Notably, this tandem system shows a remarkable open-circuit voltage of 1.4V, surpassing the constraints of liquid-based counterparts. Although performance variations between p-ssDSCs and n-ssDSCs hint at challenges related to charge recombination and the efficiency of p-ssDSCs, this study underscores the significant potential inherent in solid-state tandem configurations.
Design, synthesis, and biological characterization of proteolysis targeting chimera (PROTACs) for the Ataxia telangiectasia and RAD3-related (ATR) kinase
Authors: Alfayomy Abdallah M. , Ashry Ramy , Kansy Anita , Erdmann Frank , Schmidt Matthias , Krämer Oliver H. , Sippl Wolfgang
Published: November 2023

The Ataxia telangiectasia and RAD3-related (ATR) kinase is a key regulator of the DNA replication stress responses and DNA-damage activated checkpoints. Several potent and selective ATR inhibitors are reported and four of them are currently in clinical trials in combination with radio- or chemotherapy. Based on the idea of degrading target proteins rather than inhibiting them, we designed, synthesized and biologically characterized a library of ATR-targeted proteolysis targeting chimera (PROTACs). Among the synthesized compounds, the lenalidomide-based PROTAC 42i (Abd110) was the most promising when tested in pancreatic cancer cells (MIA PaCa-2). It reduced ATR to 40 % of the levels in untreated cells. 42i (Abd110) selectively degraded ATR through the proteasome without affecting the associated kinases ATM and DNA-PKcs. 42i (Abd110) may be a promising candidate for further optimization and biological characterization in various cancer cells.

Quantum chemical methods have been intensively applied to study the pyrolytic conversion of glucose into hydroxymethylfurfural (HMF) and furfural (FF). Herein, we collect the most relevant mechanistic proposals from the recent literature and organize them into a single reaction network. The transition structures (TSs) and intermediates are characterized using high level ab initio methods that predict relative energies within chemical accuracy. The reaction pathways are assessed in terms of the Gibbs free energy differences of the TSs and intermediates with respect to β-glucopyranose, selecting a 2D ideal-gas standard state at 773K to represent the usual pyrolysis conditions. After having scored all the possible pathways throughout the network assuming reversible reaction steps, several pathways, which present various changes with respect to the former proposals, can lead to the formation of both HMF and FF passing through rate-determining TSs that have ∆G‡ values of ~ 49-50 kcal/mol. Interestingly, the catalysis by auxiliary water molecules and the non-specific environmental effects as modelled by solvent continuum methods, have only a minor impact on the Gibbs free energy profiles of the most favoured routes. Since the HMF fragmentation (HMF→FF+CH2O) is predicted to have a small ∆rxnG value and an accessible ∆G‡ barrier, the HMF/FF molecular ratio may be partly determined by equilibrium conditions. In addition, the benchmark energies and structures are employed to study the performance of density functional methodologies. Finally, we show that the computational results are in consonance with the kinetic parameters derived from lumped models, the results of isotopic labelling experiments and the reported HMF/FF molecular ratios. Eventually, they could be useful in future computational studies focused on the kinetic modelling of the pyrolysis mechanisms including non-equilibrium kinetic effects, which could render much more detailed information about product yields and the importance of the various pathways.

Objective: This paper aims to analyze the effectiveness and safety of transurethral plasma enucleation in clinical treatment of benign prostatic hyperplasia. Methods: A total of 100 patients with benign prostatic hyperplasia who received surgical treatment in our hospital from January 2022 to January 2023 were randomly divided into groups by envelope method. 50 patients who received transurethral plasma resection of the prostate were selected as the control group and 50 patients who received transurethral plasma enucleation of the prostate were the study group. The effective rate of treatment, incidence of complications, postvoid residual (PVR) volume, maximum urinary flow rate (Qmax), and international prostate symptom score (I-PSS) were compared between the two groups. Results: By comparison, the effective rate of treatment in the study group was higher (P < 0.05). By comparison, the incidence of complications in the study group was lower (P < 0.05). Before treatment, there was no significant difference in PVR, Qmax, and I-PSS scores between the two groups (P > 0.05). After treatment, the PVR and I-PSS scores of the study group were lower, and Qmax was higher (P < 0.05). Conclusion: In the treatment of benign prostatic hyperplasia, the application of transurethral plasma enucleation can improve the clinical efficacy and clinical symptoms, with high safety and application value.

Objective: This paper aims to compare the effects of gemcitabine and pirarubicin in treating bladder cancer after electroresection. Methods: Bladder cancer patients who underwent bladder cancer resection in our hospital from January 2018 to January 2022 were selected as research subjects. According to the computer grouping method, 60 patients were divided into Group A (pirarubicin) and Group B (gemcitabine), and the therapeutic effects of the two groups of patients were compared. Results: The statistical significance of the tumor markers and related factor levels of patients in Group A and Group B before treatment was not established (P > 0.05). The levels of tumor markers and related factors of patients in Group B after treatment were lower than those of Group A (P < 0.05). There was no difference in the quality of life scores of patients in Group A and Group B before treatment (P > 0.05). After treatment, the quality of life scores of patients in Group B was higher than those in Group A (P < 0.05). The incidence rates of dysuria, hematuria, cystitis, and rash in Group B patients were less than those in group A (P < 0.05). The recurrence rate of patients in Group B was higher than in group A (P < 0.05). Conclusion: Both gemcitabine and pirarubicin are commonly used chemotherapy drugs after electroresection for bladder cancer. Compared with pirarubicin, gemcitabine is more effective and can improve the quality of life of bladder cancer patients.
