Abstract
Heating crystal samples of 9,10-diphenylanthracene endoperoxide (1) and its deuterated derivative (1-d10) to 200 °C led to singlet-oxygen chemiluminescence (CL) from the mixtures of the crystalline and molten states. To understand the events in the heated samples, the reactions of 1 and 1-d10 in crystals were investigated by powder X-ray diffraction measurements and thermal analyses. The used crystals of 1 and 1-d10 obtained from a mixture of ethyl acetate (EA) and n-hexane contained EA. Other crystals of 1 obtained by slow recrystallization with the same solvents had a solvent-free structure (form II) different from the reported one (form I). The results confirmed that the EA-containing crystals of 1 and 1-d10 were transformed to form II in two steps at 40–50 and 60–75 °C under heating at elevated temperature. Thus, the crystal samples had the form-II structure soon after heating to 200 °C. The behavior of the heated samples indicates that the crystal lattice inhibits the thermal reactivity of 1. Thus, the temperature for initiating the thermolytic reaction of 1 becomes higher than the melting point. An exploration of the potential energy surface (PES) obtained by density functional theory (DFT) calculations also supports that the deoxygenation of 1 is prevented by retaining the anthracene framework in the crystalline state. This study indicates that the method to use a CL-active compound is a powerful tool to analyze the reaction behavior in the crystalline state.

Published: July 2023

In this paper, a terahertz (THz) polarization device that achieves four polarization conversion modes with high relative bandwidth and high performance by varying the phase transition properties of vanadium dioxide (VO2) is investigated. In particular, when the device behaves as an orthogonal linear polarization converter, it has a polarization conversion ratio greater than 0.9, an operating bandwidth of 2.14 THz, and a relative bandwidth of 99.5%. In addition, the relationship between different polarization conversion modes of this polarization converter can be analyzed by the Jones matrix. The proposed VO2-based switchable THz polarization converter has important potential for applications in fields such as THz communication encryption and bio-detection.

Background
The result of published studies on the clinical outcome of peritoneal dialysis (PD) after kidney allograft failure is conflicting. There are also few published data on the outcome of patients who had PD before kidney transplant and then return to PD after allograft failure.

Methods
We reviewed 100 patients who were started on PD after kidney allograft failure between 2001 and 2020 (failed transplant group); 50 of them received PD before transplant. We compared the clinical outcome to 200 new PD patients matched for age, sex, and diabetic status (control group).

Results
The patients were followed for 45.8 ± 40.5 months. the 2-year patient survival rate was 83.3% and 87.8% for the failed transplant and control groups, respectively (log rank test, p = 0.2). The corresponding 2-year technique survival rate 66.5% and 71.7% (p = 0.5). The failed transplant and control groups also had similar hospitalization rate and peritonitis rate. In the failed transplant group, there was also no difference in patient survival, technique survival, hospitalization, or peritonitis rate between those with and without PD before transplant. In the failed transplant group, patients who had PD before transplant and then returned to PD after allograft failure had substantial increase in D/P4 (0.585 ± 0.130 to 0.659 ± 0.111, paired t-test, p = 0.032) and MTAC creatinine (7.74 ± 3.68 to 9.73 ± 3.00 ml/min/1.73m2, p = 0.047) from the time before the transplant to the time after PD was resumed after failed allograft.

Conclusions
The clinical outcome of PD patients with a failed kidney allograft is similar to other PD patients. However, patients who have a history of PD before kidney transplant and then return to PD after allograft failure have increased peritoneal transport parameters.

Volunteers are the backbone of civil society and voluntary organizations. However, there is a considerable lack of scientific studies conducted on investigating why Malaysian university students involve themselves in volunteering activities. This study aims to determine the differences in the level of students’ commitment toward volunteerism across the demographic backgrounds of respondents who participate in volunteering activities. It also tries to examine the effect of altruism on the level of students volunteering activities by using a sample taken from one of the public universities in Malaysia. A cross-sectional study among students at the University of Malaya was employed. The analysis of data based on 375 collected and usable questionnaires. The results indicated that only the gender of respondents found to be significantly different in terms of their volunteering commitment. However, it discovered that no differences in terms of ethnicity and education level of the students affect the level of dedication towards volunteerism. Lastly, the present results also revealed that the influence of altruism found to be significant on the level of students’ volunteerism. To pave the way for a successful implementation of volunteering work, the university itself must set up efforts to integrate its students into the communities that surround them. One example is the growth in community service and service-learning programmes. It envisaged that the government must see that student volunteering is a core part of developing an engaged and civil society. Thus, it is safe to say that volunteering plays a vital role in the development and wellbeing of a community.
Estudios de caso de la política exterior española hacia el Mundo Árabe y Musulmán: Países del Golfo
Authors: Saldaña Martín Marta , Montero Ramos Silvia 
Published: July 2023

A diferencia de lo que ocurre con otros países árabes, como Marruecos o Argelia, con los que además de cercanía geográfica existen fuertes vínculos históricos y culturales, las relaciones entre España y los países del Golfo han girado mayoritariamente en torno a cuestiones económicas y comerciales. En este sentido, el sector de los hidrocarburos ha sido clave, dada la alta dependencia energética de nuestro país. Por ello, parece lógico pensar que la intensificación de las relaciones por parte de España haya estado motivada por su necesidad de garantizarse un suministro energético que obligatoriamente ha de importar. No obstante, en los últimos años se han identificado nuevas oportunidades de cooperación recíprocas que han permitido a España reforzar su presencia a través de la implantación de empresas españolas en la región y de la puesta en marcha de proyectos en sectores tan diversos como las infraestructuras, las energías renovables o la cooperación cultural. De hecho, el análisis de los datos recogidos en la BDPEX refleja un incremento de las relaciones y de los intercambios comerciales y, por tanto, una voluntad por parte de España de afianzar su presencia en estos países. AbstractUnlike the relations with other countries that share with Spain stronger geographical, historical and cultural ties, such as Morocco or Algeria, relations between Spain and the GCC states have mainly evolved around economic and commercial issues. In this sense, the energy sector has been key given Spain’s dependence on gas and oil imports. Therefore, we could assume that guaranteeing this supply has been a powerful reason to reinforce the relations with these countries. Nevertheless, new fields of opportunity, mainly in the sectors of infrastructures, renewable energy and culture, have been identified during the past years, thus allowing for mutual cooperation and, even more important, for the arrival of Spanish companies to the region. The analysis of the data gathered by BDPEX reflects, indeed, an increase in the flux of relations and commercial exchanges between Spain and the GCC states, which illustrates Spain’s will of consolidating its presence in the region.

Aim: to reveal morphological features of paraurethral tissue in postmenopausal women with stress urinary incontinence (SUI).Materials and Methods. A prospective cross-sectional trial was conducted, which included 30 women with SUI combined with POP-Q (Pelvic Organ Prolapse Quantification) stage I–II cystocele, aged 55 to 75 years. All patients underwent surgical treatment such as anterior colporrhaphy, cystocele plasty with own tissues, urethropexy with synthetic loop followed by morphological study of histological samples.Results. Profound alterations in architectonics of the connective tissue were revealed. Structural changes occurring in the paraurethral tissue are characterized by fragmentation of collagen and elastin fibers as well as their critically lowered thickness and volume, and destruction of strong inter-fiber bonds. This indicates about disintegration of the collagen-elastin skeleton being a part of the ligamentous apparatus involved in urinary retention.Conclusion. The study of the morphological aspects related to stress incontinence including use of immunohistochemical research methods will provide deeper insights into pathogenetic mechanisms behind such pathological condition. Thus, it will be possible to implement a personalized approach to the tactics of management and the choice of therapeutic method for patients with SUI aimed to increase in its effectiveness.
Isolation, identification and frequency of isolated uropathogens with their antibiotic susceptibility pattern causing urinary tract infections in patients of Ujjain M.P. (India)
Authors: Bhonsle Kaina , Vyas Alka , Vyas Harish 
Published: July 2023

At present, resistance of uropathogenic bacteria towards different antibiotics is increasing worldwide due to improper, nonspecific and uncontrolled use of antibiotics; hence the treatment of UTI becomes difficult. These resistant uropathogens are major cause of increased rate of morbidity and mortality. This study was conducted to investigate frequency of causal bacterial agents of UTI and their antibiotics susceptibility pattern.The present study was conducted on total 770 urine samples from suspected patients of urinary tract infections, these samples were collected over the period of one year November 2018- October 2019 from different hospitals of Ujjain. Uropathogens were isolated and identified from collected urine sample by biochemical tests and their susceptibility pattern was studied against different antibiotics by Kirby Bauer Disc Diffusion method.A total of 770 urine samples were collected among which 486 (63.1%) samples were tested positive for urinary tract infection in their analysis and prevalence was found higher in female patients (71.6%) as compare to male patients (28.4%). The most common isolated uropathogens were (45.6%), (27.1%), (15.6%), (7.4%) and (4.1%).These isolated uropathogens were highly susceptible to Doripenem, Meropenem, Imepenem, Gentamicin, Piperacillin/Tazobactam, Vancomycin, Linezolid and Rifampin.Due to high prevalence of uropathogens and increased rate of resistance among uropathogens, continued surveillance on uropathogens and their resistance is needed for its proper treatment. So the choice of drug for the treatment of urinary tract infections becomes narrow and its treatment is based on local antimicrobial sensitivity of uropathogens to prevent treatment failure and misuse of antibiotics.
Intelligent Syringe for Porous Tissue Characterization Using Advanced Darcy Flow Pressure Transient Analysis
Authors: Chin Wilson C. , Chin Jamie A. , Zhuang Xiaoying 
Published: July 2023

Abstract
An instrumented “intelligent syringe” for tissue properties prediction is described. The syringe records pressure transients created while injecting or withdrawing fluid from tissue at given flow rates. Dynamic data is interpreted using computer-based porous media math models to predict permeability, anisotropy, compressibility, background pressure and porosity. The new method provides direct measurements of flow properties important to drug delivery, clinical diagnosis, disease control, synthetic organ design and research endeavors. The approach conveniently, rapidly and inexpensively supplements conventional methods like X-ray, Catscan, MRI and ultrasound, which offer qualitative results through gray scale images requiring physician dependent and subjective analysis. The “iSyringe” supports portable target monitoring on daily or weekly bases; it provides local quantitative information useful in understanding global qualitative results obtained from traditional methods. The theoretical foundations of the method are derived, validated mathematically, and applied to published human and animal data, highlighting potential clinical and research applications.

Abstract

The use of carbon fibre (CF) based composites is of growing global importance due to their applications in high end sectors such aerospace, automotive, construction, sports and leisure amongst others. It is forecast that composites will reach a global market value of $131.6 bn by 2024. However, their current high production cost, high carbon footprint and reduced production capability, limits their use to high performance and luxury applications. Approximately 50 % of the total cost of CF production is due to the thermal conversion of PAN precursor fibre (PF) to CF as it involves the use of high energy consumption and low heating efficiency large furnaces. Looking at this scenario we propose in the present study to use microwave (MW) heating to convert PF to CF. This is scientifically and technologically challenging since PF does not absorb microwave energy. Here, for the first time we show how carbonisation temperatures of >1000 ºC can be reached in a matter of seconds through the use of a novel microwave (MW) susceptor nanocoating methodology developed via a Layer-by-layer assembly of multiwall carbon nanotubes (MWCNTs) on the PF surface. Remarkably, these CFs can be produced in an inexpensive domestic microwave and exhibit mechanical performance equivalent to CF produced using conventional heating. Additionally, we provide a life cycle and environmental impact analysis which shows that MW heating reduces the energy demand and environmental impact of lignin-based CF production by up to 66.8% and 69.5%, respectively.
Pure large cell neuroendocrine carcinoma of the ovary with a somatic BRCA1 mutation: the first reported case and the review of the literature
Authors: Wang Musen , Gao Fei , Wang Xiao , Guo Yebing , Zhang Hongkai 
Published: July 2023

Abstract
Pure large cell neuroendocrine carcinomas (pLCNEC) of the ovary are extremely rare, so there is a lack of molecular information on this type of cancer. Herein, we presented a pure primary LCNEC of the ovary with a pathogenic somatic mutation at the c.5332 + 1g > a splice site of the BRCA1 gene. To the best of our knowledge, this is the first report of a BRCA1 somatic mutation found in the ovary LCNEC. Testing BRCA1/2 mutations in patients with ovarian LCNEC might be worth considering, as these patients may benefit from the targeted treatment. We present a unique case that expands our understanding of this rare entity.

Abstract
Background

Diagnosis of tuberculous meningitis (TBM) is hampered by the lack of a gold standard. Current microbiological tests lack sensitivity and clinical diagnostic approaches are subjective. We therefore built a diagnostic model that can be used before microbiological test results are known.

Methods

We included 659 individuals aged at least 16 years with suspected brain infection from a prospective observational study conducted in Vietnam. We fitted a logistic regression diagnostic model for TBM status, with unknown values estimated via a latent class model on three mycobacterial tests: Ziehl-Neelsen smear, Mycobacterial culture, and GeneXpert. We additionally re-evaluated mycobacterial test performance, estimated individual mycobacillary burden, and quantified the reduction in TBM risk after confirmatory tests were negative. We also fitted a simplified model and developed a scoring table for early screening. All models were compared and validated internally.

Results

Participants with HIV, miliary TB, long symptom duration, and high cerebrospinal fluid (CSF) lymphocyte count were more likely to have TBM. HIV and higher CSF protein were associated with higher mycobacillary burden. In the simplified model, HIV infection, clinical symptoms with long duration, and clinical or radiological evidence of extra-neural TB were associated with TBM At the cutpoints based on Youden’s Index, the sensitivity and specificity in diagnosing TBM for our full and simplified models were 86.0% and 79.0%, and 88.0% and 75.0% respectively.

Conclusion

Our diagnostic model shows reliable performance and can be developed as a decision assistant for clinicians to detect patients at high risk of TBM.
A Unified Kinetic Picture of Heterogeneous and Homogeneous Crystallization from Transition Rate
Authors: Xu Lei , Chen Zhen 
Published: July 2023

Abstract
Heterogeneous and homogeneous crystallization exhibit distinct phase transition kinetics. However, due to the difficulty of realizing both heterogeneous and homogeneous crystallization under one identical thermodynamic condition, an independent comparison of the two remains lacking. Inside a colloidal system, we experimentally realize a systematic switching from heterogeneous to homogeneous crystallization under one identical thermodynamic condition, capture the entire crystallization process of each colloidal particle with confocal microscopy, and discover a universal kinetic picture of the two situations. In the heterogeneous crystallization, we reveal an unexpected variation of critical nucleus size with boundary disorderness instead of contact angle, which violates the classical nucleation theory but enables the systematic switching. Moreover, analogous to the reaction rate in chemical reactions, we theoretically propose and experimentally measure the crystallization transition rate, which quantifies the transition probability between any two crystallization intermediate structures identified by the bond order parameters. To our surprise, regardless of heterogeneous or homogeneous crystallization, all 22 kinetic transition rates fall onto universal master curves throughout both nucleation and growth stages, which unifies the two distinct crystallization situations into a universal kinetic picture, i.e., all transition probabilities only depend on the local order parameter but not the heterogeneous or homogeneous mode.
