Integrated agronomic, physiological, microstructure, and whole-transcriptome analyses reveal the role of biomass accumulation and quality formation during Se biofortification in alfalfa
Authors: Wang Qingdong , Hu Jinke , Lou Tongbo , Li Yan , Shi Yuhua , Hu Huafeng
Published: July 2023

Se-biofortified agricultural products receive considerable interest due to the worldwide severity of selenium (Se) deficiency. Alfalfa (Medicago sativa L.), the king of forage, has a large biomass, a high protein content, and a high level of adaptability, making it a good resource for Se biofortification. Analyses of agronomic, quality, physiological, and microstructure results indicated the mechanism of biomass increase and quality development in alfalfa during Se treatment. Se treatment effectively increased Se content, biomass accumulation, and protein levels in alfalfa. The enhancement of antioxidant capacity contributes to the maintenance of low levels of reactive oxygen species (ROS), which, in turn, serves to increase alfalfa’s stress resistance and the stability of its intracellular environment. An increase in the rate of photosynthesis contributes to the accumulation of biomass in alfalfa. To conduct a more comprehensive investigation of the regulatory networks induced by Se treatment, the transcriptome sequencing of non-coding RNA (ncRNA) was employed to compare 100 mg/kg Se treatment and control groups. The analysis identified 1,414, 62, and 5 genes as DE-long non-coding RNAs (DE-lncRNA), DE-microRNAs (DE-miRNA), and DE-circular RNA (DE-circRNA), respectively. The function of miRNA-related regulatory networks during Se biofortification in alfalfa was investigated. Subsequent enrichment analysis revealed significant involvement of transcription factors, DNA replication and repair mechanisms, photosynthesis, carbohydrate metabolism, and protein processing. The antioxidant capacity and protein accumulation of alfalfa were regulated by the modulation of signal transduction, the glyoxalase pathway, proteostasis, and circRNA/lncRNA-related regulatory networks. The findings offer new perspectives on the regulatory mechanisms of Se in plant growth, biomass accumulation, and stress responses, and propose potential strategies for enhancing its utilization in the agricultural sector.
Examining the effects of teacher self-compassion, emotion regulation, and emotional labor strategies as predictors of teacher resilience in EFL context
Authors: Hu Yan
Published: July 2023

Introduction

This study investigates the effects of teacher self-compassion, emotion regulation, and emotional labor strategies on teacher resilience in the English as a foreign language (EFL) context. The study aims to understand the relationships between these variables and their potential implications for promoting teacher resilience.

Methods

A sample of 711 Chinese EFL teachers participated in the study. Confirmatory factor analysis (CFA) was conducted to assess the psychometric properties of the instruments used to measure teacher self-compassion, emotion regulation, emotional labor strategies, and teacher resilience. Structural equation modeling (SEM) was employed to examine the relationships between these variables.

Results

The results of the study revealed that teacher self-compassion and emotional labor strategies had direct positive effects on teacher resilience. Specifically, higher levels of self-compassion and effective use of emotional labor strategies were associated with greater teacher resilience. Furthermore, teacher emotion regulation was found to indirectly predict teacher resilience through the mediation of emotional labor strategies. This suggests that the ability to regulate emotions influences the adoption of effective emotional labor strategies, which in turn contributes to higher levels of teacher resilience.

Discussion

The findings of this study highlight the importance of teacher self-compassion, emotion regulation, and emotional labor strategies in promoting teacher resilience in the EFL context. Interventions aimed at enhancing teacher emotional regulation skills and fostering self-compassion may have significant implications for supporting teachers in managing the demands and challenges of their profession, ultimately enhancing their resilience. These findings contribute to the understanding of factors that can promote teacher resilience and inform the development of targeted interventions in the EFL context.

Published: July 2023

Oil-in-water emulsions provide an essential contribution to enhanced oil recovery by acting as oil displacement and conformance control systems. However, the dominant factors affecting their emulsification and kinetics are unclear. The emulsification rate is usually defined in terms of changes in the torque, conductivity, or particle size over time, which results in inaccurately calculated emulsified oil amounts. Therefore, the effects of temperature, pH, and NaCl concentration on the emulsified mass and droplet sizes of aqueous emulsions of Jin8-7 and Chen373 oil with octadecyl amine ethoxylate ether as an emulsifier were investigated. The results showed that the formation of oil-in-water emulsions of Jin8-7 and Chen373 under different conditions occurred via a two-stage mechanism: rapid emulsification and emulsion maturation. The emulsified oil mass rapidly increased during the rapid emulsification period and plateaued during the emulsion maturation period. This indicates that the emulsified oil mass largely depended on the short rapid emulsification period. It was also found that increasing the temperature and pH were more conducive to the emulsification of Chen373 oil with a high viscosity and high asphaltene content. The optimal NaCl concentration was determined to be 2% and 4% for Chen373 and Jin8-7 oil, respectively, based on the emulsification mass during the rapid emulsification period. The droplet size decreased first and then increased during the emulsification process under most experimental conditions. A second-order kinetics model for emulsification was proposed, in which the evolution of emulsified oil mass calculated with time agreed with the experimentally measured values. This study can provide theoretical guidance for the implementation of chemical cold production of heavy oil in oilfields.
Strong Enough to Fight: Harriet Tubman vs. The Myth of the Lost Cause
Authors: Dubek Laura
Published: July 2023

Black creators who tell Harriet Tubman’s story engage in an ongoing rhetorical battle over historical memory with regard to slavery and the Civil War. This essay examines the challenges Tubman’s story poses to a Lost Cause narrative that took root in the nineteenth-century and manifests in the work of celebrated children’s author Robert Lawson. Reading Ann Petry’s YA biography Harriet Tubman: Conductor on the Underground Railroad (1955), Jacob Lawrence’s picture book Harriet and the Promised Land (1968), and Kasi Lemmons’ film Harriet (2019) together, and within the context of Lawson’s award-winning They Were Strong and Good (1940) and his historical primer Watchwords of Liberty: A Pageantry of American Quotations (1943) offers an opportunity to assess the rhetorical firepower of creative work about a historical figure who continues to fascinate people of all ages. Such reading also underscores the extent to which the apartheid in and of children’s literature limits the imaginations of critics, thereby hindering efforts to promote social justice.
Review on the Chemistry of [M(NH3)n](XO4)m (M = Transition Metal, X = Mn, Tc or Re, n = 1–6, m = 1–3) Ammine Complexes
Authors: Mehrotra Raj Narain
Published: July 2023

The preparation of ammine complexes of transition metals having oxidizing anions such as permanganate and perrhenate ions is a great challenge due to possible reactions between ammonia and oxidizing anions during the synthesis of these materials. However, it has an important role in both the development of new oxidants in organic chemistry and especially in the preparation of mixed-metal oxide catalyst precursors and metal alloys for their controlled temperature decomposition reactions. Therefore, in this paper, synthetic procedures to prepare ammonia complexes of transition metal permanganate, pertechnetate, and perrhenate (the VIIB group tetraoxometallates) salts have been comprehensively reviewed. The available data about these compounds’ structures and spectroscopic properties, including the presence of hydrogen bonds that act as redox reaction centers during thermal decomposition, are given and evaluated in detail. The nature of the thermal decomposition products has also been summarized. The available information about the role of the ammine complexes of transition metal permanganate salts in organic oxidation reactions, such as the oxidation of benzyl alcohols and regeneration of oxo-compounds from oximes and phenylhydrazones, including the kinetics of these processes, has also been collected. Their physical and chemical properties, including the thermal decomposition characteristics of known diammine (Ag(I), Cd, Zn, Cu(II), Ni(II)), triammine (Ag(I)), and simple or mixed ligand tetraammine (Cu(II), Zn, Cd, Ni(II), Co(II), Pt(II), Pd(II), Co(III)), Ru(III), pentaammine (Co(III), Cr(III), Rh(III) and Ir(III)), and hexaammine (Ni(II), Co(III), Cr(III)) complexes of transition metals with tetraoxometallate(VII) anions (M = Mn, Tc and Re), have been summarized. The preparation and properties of some special mixed ligand/anion/cation-containing complexes, such as [Ru(NH3)4(NO)(H2O)](ReO4)2, [Co(NH3)5(H2O)](ReO4)2, [Co(NH3)5X](MnO4)2 (X = Cl, Br), [Co(NH3)6]Cl2(MnO4), [Co(NH3)5ReO4]X2 (X = Cl, NO3, ClO4, ReO4), and K[Co(NH3)6]Cl2(MnO4)2, are also included.
Space Charge Characteristics at the Interface of Laminated Epoxy Resin

Published: July 2023

In the design and manufacturing of epoxy resin insulation components, complex structures can be achieved through multiple pours, thereby forming the structure of interface of laminated epoxy resin. This type of interface structure is often considered a weak link in performance which can easily accumulate charges and cause electric field distortion. However, research on the interlayer interface of epoxy resin has received little attention. In this study, epoxy samples with and without interlayer interfaces were prepared, and the space charge accumulation characteristics and trap characteristics of the samples were analyzed via pulsed electro-acoustic (PEA) and thermally stimulated depolarization current (TSDC) methods. The experimental results indicate that the Maxwell–Wagner interface polarization model cannot fully explain the charge accumulation at the interface. Due to the influence of the secondary curing, the functional groups in the post-curing epoxy resin can move and react with the partially reacted functional groups in the prefabricated epoxy resin layer, resulting in a weak cross-linking network at the interface. With the increase in temperature, the molecular chain segments in the weak cross-linked region of the interface become more active and introduce deep traps at the interface, thereby exacerbating the accumulation of interface charges. In addition, due to the influence of interface polarization and weak cross-linking, the ability of the interface charges to cause field strength distortions decreases with the increase in applied field strength. This research study can provide a theoretical reference for the interfacial space charge transport characteristics of epoxy-cured cross-linked layers and provide ideas for regulating interfacial cross-linking to suppress interfacial charge accumulation.

Published: July 2023

Chlorogenic and isochlorogenic acids are naturally occurring antioxidant dietary polyphenolic compounds found in high concentrations in plants, fruits, vegetables, coffee, and coffee by-products. The objective of this review was to assess the potential health risks associated with the oral consumption of coffee by-products containing chlorogenic and isochlorogenic acids, considering both acute and chronic exposure. An electronic literature search was conducted, revealing that 5-caffeoylquinic acid (5-CQA) and 3,5-dicaffeoylquinic acid (3,5-DCQA) are the major chlorogenic acids found in coffee by-products. Toxicological, pharmacokinetic, and clinical data from animal and human studies were available for the assessment, which indicated no significant evidence of toxic or adverse effects following acute oral exposure. The current state of knowledge suggests that long-term exposure to chlorogenic and isochlorogenic acids by daily consumption does not appear to pose a risk to human health when observed at doses within the normal range of dietary exposure. As a result, the intake of CQAs from coffee by-products can be considered reasonably safe.

Colon cancer is one of the most common types of cancer worldwide, and its incidence is increasing. Despite advances in medical science, the treatment of colon cancer still poses a significant challenge. This study aimed to investigate the potential protective effects of Adiantum pedatum (AP) extract and/or piceatannol on colon cancer induced via phenylhydrazine (PHZ) in terms of the antioxidant and apoptotic pathways and histopathologic changes in the colons of male albino rats. The rats were randomly divided into eight groups: control, AP extract, piceatannol (P), PHZ, PHZ and AP treatments, PHZ and P treatments, PHZ and both AP and P, and PHZ and prophylaxis with both AP and P. The results demonstrated that PHZ induced oxidative damage, apoptosis, and histopathological changes compared to the control group. However, the administration of AP or P or AP + P as therapy or prophylaxis significantly ameliorated these changes and upregulated the colonic mir-145 and mRNA expression of P53 and PDCD-4 while downregulating the colonic mRNA expression of PI3K, AKT, c-Myc, CK-20, SOX-2, OCT-4, and NanoG compared to the PHZ group. These findings suggest that the candidate drugs may exert their anti-cancer effects through multiple mechanisms, including antioxidant and apoptotic activities.
Shape-Persistent Dendrimers
Authors: Lu Yao-Chih , Anedda Roberto , Lai Long-Li
Published: July 2023

Dendrimers have a diverse and versatile morphology, frequently consisting of core, linking, and peripheral moieties. Dendrimers with flexible linkers, such as PAMAM, cannot retain the persistent shape of molecules, and this has been widely explored and reviewed previously; nevertheless, dendrimers with stiff linkers can preserve the persistent shape of the dendrimers, which has been reported considerably less. This review thus focuses on addressing shape-persistent dendrimers with rigid linking moieties discovered in recent years, i.e., from 2012 to 2023. Shape-persistent dendrimers with an interstitial gap between the dendritic frames in the solid state may or may not let the intramolecular void space be accessible for guest molecules, which largely depends on whether their peripheral groups are flexible or non-flexible. In this paper, eight articles on shape-persistent dendrimers with a flexible alkyl periphery, which may exhibit mesogenic phases upon thermal treatment, and eight articles on shape-persistent dendrimers with a non-flexible periphery, which may allow external ions, gases, or volatile organic compounds to access the interstitial gaps between dendritic frames, are reviewed.
Chemical Analysis of Gunpowder and Gunshot Residues
Authors: Serol Miguel , Ahmad Samir Marcos , Quintas Alexandre , Família Carlos
Published: July 2023

The identification of firearms is of paramount importance for investigating crimes involving firearms, as it establishes the link between a particular firearm and firearm-related elements found at a crime scene, such as projectiles and cartridge cases. This identification relies on the visual comparison of such elements against reference samples from suspect firearms or those existing in databases. Whenever this approach is not possible, the chemical analysis of the gunpowder and gunshot residue can provide additional information that may assist in establishing a link between samples retrieved at a crime scene and those from a suspect or in the identification of the corresponding model and manufacturer of the ammunition used. The most commonly used method for the chemical analysis of gunshot residue is scanning electron microscopy with energy dispersive X-ray, which focuses on the inorganic elements present in ammunition formulation, particularly heavy metals. However, a change in the legal paradigm is pushing changes in these formulations to remove heavy metals due to their potential for environmental contamination and the health hazards they represent. For this reason, the importance of the analysis of organic compounds is leading to the adoption of a different set of analytical methodologies, mostly based on spectroscopy and chromatography. This manuscript reviews the constitution of primer and gunpowder formulations and the analytical methods currently used for detecting, characterising, and identifying their compounds. In addition, this contribution also explores how the information provided by these methodologies can be used in ammunition identification and how it is driving the development of novel applications within forensic ballistics.

Electrochemical oxidation of 1-R-substituted silatranes 1 (R = Me, vinyl, (CH2)2CN, CH2Ph, CH2(C10H7), Ph, C6H4Me, p-Cl-C6H4, Cl)—classical representatives of pentacoordinated silicon compounds—and the formation of their short living cation radicals upon reversible or quasi-reversible one-electron withdrawal were studied by means of cyclic and square-wave voltammetry, faradaic impedance spectroscopy and real-time temperature-dependent EPR spectroelectrochemistry supported by DFT B3PW91/6-311++G(d,p) (C-PCM, acetonitrile) calculations. The main reaction responsible for the decay of 1+• is shown to be their deprotonation, and ways of increasing the stability of these species are proposed.

Published: July 2023

Objective:
We aim to develop a polymer library consisting of phenylalanine-based poly(ester amide)s (Phe-PEAs) for cancer therapy and investigate the structure–property relationship of these polymers to understand their impact on the drug delivery efficiency of corresponding nanoparticles (NPs).
Impact Statement:
Our study provides insights into the structure–property relationship of polymers in NP-based drug delivery applications and offers a potential polymer library and NP platform for enhancing cancer therapy.
Introduction:
Polymer NP-based drug delivery systems have demonstrated substantial potential in cancer therapy by improving drug efficacy and minimizing systemic toxicity. However, successful design and optimization of these systems require a comprehensive understanding of the relationship between polymer structure and physicochemical properties, which directly influence the drug delivery efficiency of the corresponding NPs.
Methods:
A series of Phe-PEAs with tunable structures was synthesized by varying the length of the methylene group in the diol part of the polymers. Subsequently, Phe-PEAs were formulated into NPs for doxorubicin (DOX) delivery in prostate cancer therapy.
Results:
Small adjustments in polymer structure induced the changes in the hydrophobicity and thermal properties of the PEAs, consequently NP size, drug loading capacity, cellular uptake efficacy, and cytotoxicity. Additionally, DOX-loaded Phe-PEA NPs demonstrated enhanced tumor suppression and reduced side effects in prostate tumor-bearing mice.
Conclusion:
Phe-PEAs, with their finely tunable structures, show great promise as effective and customizable nanocarriers for cancer therapy.

Formação universitária e responsabilidade social: Notas reflexivas para o debate em Angola
Authors: da Silva Abel José , Moisés Irene Jamba Inakulo
Published: July 2023

Nesta reflexão, que se fundamenta na revisão bibliográfica, coloca-se em debate a relação entre formação universitária e responsabilidade social em Angola. Reitera-se o entendimento de que não pode haver desenvolvimento sem formação, assunto que ganha relevância quando relacionado com o Ensino Superior. A responsabilidade social dessa formação decorre da possibilidade do acesso ao saber para fazer da vida social um espaço de realização mais harmonioso, que expressa um novo modo de ser. Formação universitária e responsabilidade social são compreendidas como duas dimensões fundamentais para perceber a tarefa da Universidade e funcionam como indicadores essenciais para determinar o desenvolvimento sustentável de povos e nações no século XXI, porque, com alterações profundas da vida humana, este contexto exige capacidade de lidar com elas de forma menos traumática nas dimensões políticas, económicas, sociais, culturais, ecológicas, humanitárias. Esta capacitação para enfrentar mudanças globais de forma menos traumática e mais criativa constitui o maior desafio de quem se forma em Instituições do Ensino Superior. Como resultado desta reflexão, compreende-se que a magnitude e qualidade de oportunidades de formação universitária podem estar em estreita proporção com as oportunidades de participar dos processos de desenvolvimento dos países e de usufruir dos seus benefícios. Esta lógica não pode ser uma excepção em Angola que, por exemplo, tem, entre outros países da Comunidade para o Desenvolvimento da África Austral (SADC), mais necessidade de valorizar os recursos humanos como o activo mais decisivo para projectar o país na linha do desenvolvimento social e humano.

El abasto por medio de la distribución comercial permite a las personas tener a su alcance y adquirir tanto productos como servicios para satisfacer sus necesidades, en el último siglo estos establecimientos se han diversificado en mayoristas y minoristas, siendo estos subclasificados en modernos y tradicionales que comparten mercados similares. A partir de lo cual la literatura ha identificado tendencias y debates que parecen contraponer uno sobre otro por sus diferencias principalmente en grandes ciudades. Este trabajo se planteó como objetivo describir las principales características socioeconómicas del comercio al por menor en particular lo referente a tiendas de abarrotes y tiendas de conveniencia en Zapopan, Jalisco, México. Entre los resultados resalta que las tiendas de abarrotes han disminuido porcentualmente mientras las tiendas de conveniencia han incrementado su cantidad, así como el personal remunerado en el municipio de estudio por lo cual se identificó que han decrecido, pero no desaparecido como lo plantea la literatura. Se concluye que en el comercio minorista tradicional existen elementos de índole social sobre los cuales se sustentan aspectos económicos que les han permitido mantenerse en el mercado, de tal manera que se invita a continuar con abordajes de estos establecimientos desde perspectivas multidisciplinares en distintos intervalos de tiempo.

MSMEs can seek assistance from various sources, such as governments, business organizations, and financial institutions, to access the resources and information needed to adopt new technologies and develop technological innovations that can help them gain a competitive advantage. Furthermore, to overcome the problem of market orientation in MSMEs, efforts are needed to increase understanding of market needs, utilize market research, focus on market needs and wants, have a clear marketing strategy, and increase available resources
Structure of the W3A Low-density Foreground Region
Authors: Goldsmith Paul. F. , Langer William D. , Seo Youngmin , Pineda Jorge , Stutzki Jürgen , Guevara Christian , Aladro Rebeca , Justen Matthias
Published: July 2023

We present analysis of [O i] 63 μm and CO J = 5 − 4 and 8 − 7 multiposition data in the W3A region and use it to develop a model for the extended low-density foreground gas that produces absorption features in the [O i] and J = 5 − 4 CO lines. We employ the extinction to the exciting stars of the background H ii region to constrain the total column density of the foreground gas. We have used the Meudon photodissociation region code to model the physical conditions and chemistry in the region employing a two-component model with a high-density layer near the H ii region responsible for the fine-structure line emission and an extended low-density foreground layer. The best-fitting total proton density, constrained largely by the CO lines, is n(H) = 250 cm−3 in the foreground gas and 5 × 105 cm−3 in the material near the H ii region. The absorption is distributed over the region mapped in W3A and is not restricted to the foreground of either the embedded exciting stars of the H ii region or the protostar W3 IRS5. The low-density material associated with regions of massive-star formation, based on an earlier study by Goldsmith et al., is quite common, and we now see that it is extended over a significant portion of W3A. It thus should be included in modeling of fine-structure line emission, including interpreting low-velocity-resolution observations made with incoherent spectrometer systems, in order to use these lines as accurate tracers of massive-star formation.
Radiative Acceleration of Dense Circumstellar Material in Interacting Supernovae
Authors: Tsuna Daichi , Murase Kohta , Moriya Takashi J.
Published: July 2023

Early-time light curves/spectra of some hydrogen-rich supernovae (SNe) provide solid evidence of the existence of confined, dense circumstellar matter (CSM) surrounding dying massive stars. We numerically and analytically study the radiative acceleration of CSM in such systems, where the radiation is mainly powered by the interaction between the SN ejecta and the CSM. We find that the acceleration of the unshocked dense CSM ahead of the shock is larger for massive and compact CSM, with velocities reaching up to ∼103 km s−1 for a CSM of order 0.1 M
⊙ confined within ∼1015 cm. We show that the dependence of the acceleration on the CSM density helps us explain the diversity of the CSM velocity inferred from the early spectra of some Type II SNe. For explosions in even denser CSM, radiative acceleration can affect the dissipation of strong collisionless shocks formed after the shock breakout, which would affect early nonthermal emission expected from particle acceleration.
Retour aux sources ? Le New Age au sud dans une perspective globale, ou le néopaganisme en question

L’étude systématique de ces points et des convergences parfois insoupçonnées entre les discours et les pratiques néopaïens rencontrés au sud du Sahara, ailleurs dans le Sud global et dans les contextes post-communistes asiatiques ou européens contribue à la fois à la meilleure compréhension du New Age et du lien entre religion et nationalisme en général.
Ridum : un concept de tradition dans une « société traditionnelle »
Authors: Schlemmer Grégoire
Published: July 2023

Ridum est un terme kulung rai (une population du Népal oriental) que l’on peut facilement rapprocher de notre notion de tradition. Je propose d’explorer le champ sémantique de ce terme polysémique. Ce faisant, il s’agit de penser une société par ses propres termes, d’enrichir notre notion de tradition en participant à la construction d’un appareil conceptuel moins ethnocentré, mais aussi d’esquisser un questionnement méthodologique sur la manière d’approcher des notions abstraites sans référent évident, ainsi qu’une réflexion sur l’épistémologie de ce que l’on pourrait nommer le savoir traditionnel.
The spectacular ordinariness of the Arabian Gulf in Kerala: Exploring the thing of migration
Authors: Karinkurayil Mohamed Shafeeq
Published: July 2023

The migration from the Indian state of Kerala to the Arabian Gulf is credited with giving rise to consumerist culture. The households of Gulf migrants in Kerala are found to have better access to technology and improved conditions of living. The cultural matrix in which these technologies and foreign goods made their meanings and mobilize affects is under-researched. Taking the case of a canned powdered milk, Nido, as a spectral presence of the Gulf in Kerala, this paper, veered towards a singular reading drawing on mainstream films, and a variety of Keralan Gulf migrant archives, examines the ways in which the canned milk powder entered existing cultural values and produced discourses around itself, while also being an excess to discourse. The paper illustrates the enmeshed nature of migration, in which materials cross borders and purposes, is imputed with essences, or pass on from the spectacular to the quotidian. The paper argues that the contradictions of the Gulf migration — the limits of migration induced mobility in Kerala on the one hand, and the denial of citizenship in the Gulf on the other — is resolved through spectrality that the Gulf migration is projected and experienced as.
Political entanglements between Pakistan and Kuwait: the transnational figuration of migration, development and charity
Authors: Bouzas Antía Mato
Published: July 2023

This article examines interactions between Pakistan and the Gulf region with a focus on a case study of mobilities between the southern part of Gilgit-Baltistan (Baltistan), in north-eastern Pakistan, and the state of Kuwait. Moving away from state approaches, this study examines a transnational figuration formed by migrants and religious leaders from Baltistan and members of the Kuwaiti merchant class as a way to ground an understanding of this transnational engagement and its transformative character, mainly for Baltistan but also for Kuwait. Gilgit-Baltistan is a disputed territory and state presence is marginal. The relative absence of the state creates a situation in which people feel the need to fend for themselves. In this context, foreign development and charity work can become a source of empowerment. The Gulf, and concretely, Kuwait exercises an influence in Baltistan via migration, development and charity work.The study of this transnational figuration unfolds how social norms (in terms of a political culture), status, power and social capital help to shape politics in this region of north-eastern Pakistan. Indirectly, this figuration reveals the relatively influential role exercised by the Gulf and, in this case Kuwait, in other regions through a soft diplomacy of development and charity work, but one that has results in political empowerment of this border area of Pakistan. It also shows that this ‘foreign’ activity of Kuwaiti actors responds to forms of seeking political empowerment at home.
Merchants without Borders: Quṣmân Traders in the Arabian Gulf and the Indian Ocean, c. 1850-1950
Authors: al-Sharida Mansur
Published: July 2023

In order to map the network of al-Qaṣîm’s external trade and demonstrate the impact of their trade on both al-Qasim specifically and the whole region generally, this article follows the Qusmân traders’ economic activities in the Arabian Gulf and Indian Ocean during the second half of the 19th century and the first half of the 20th century. The paper finds that Quṣmân who migrated to the commercial centers of the Arabian Gulf and the Indian Ocean traded in anything available and profitable, such as slaves, horses, pearls, gold, currency, weapons, textile, carpets, dates, spice, rice, sugar, tea, coffee, and perfume. It concludes that since the Quṣmân could find foreign markets for al-Qaṣîm’s local products and brought in goods and foreign currency to their region, making al-Qaṣîm an entrepôt in Najd, their business demonstrated that Najd was incorporated into the global economy by the 19th century, if not even earlier.
Indian Ocean networks of Daʿwa, Tijāra, and Khizāna: The Bohras as Manuscript Agents in Yemen
Authors: Akkerman Olly
Published: July 2023

This article focuses on the question of the circulation of manuscripts and khizānāt al-kutub (book treasuries) between the Arabian Peninsula and the Indian Subcontinent in the early modern period. More specifically, it explores how a mercantile Shiʿi Ismaʿili community, known as the Ṭayyibī Bohras, operated between Gujarat and Yemen as merchant tycoons, students, pilgrims, administrators, benefactors, and scholars. Drawing on the content as well as the materiality of sources from the Bohra khizāna, I argue that the Indian Bohras were key actors among the Ismaʿilis in Yemen, politically, economically, and socially, rather than passive students and disciples. Via their communal Indian Ocean networks of daʿwa (community) and tijāra (trade), they played a vital role in facilitating the network of mobility and learning of Indian students to Yemen, as well as financing the daʿwa, and securing its survival in India by sending, copying, and requesting manuscripts overseas, a process which continued well into the nineteenth century.
L’ambiguïté d’une relation amicale : Nietzsche et Strindberg
Authors: Attali Patrick
Published: July 2023

Cet article porte sur la correspondance entre Friedrich Nietzsche et August Strindberg. Il précise en premier lieu les circonstances dans lesquelles les deux hommes se sont « rencontrés » : de fait, un intermédiaire avisé a joué, à l’arrière-plan, un rôle capital. Mais, en tentant de comprendre plus avant leurs motivations, l’équivoque « sulfureuse » de leurs desseins « misogynes » se fait jour. Deux manières de traiter la difficulté sont envisagées. D’une part, il s’agit d’examiner si les ténèbres de telles considérations ne pourraient pas être adoucies par un exercice d’interprétation qui consiste à croiser la lecture de textes du philosophe avec l’analyse d’une grande œuvre dramatique du Suédois. Nous avançons, d’autre part, l’idée que l’ambiguïté, qu’il serait vain de prétendre éliminer, peut être vue, à contre-courant de nos habitudes, comme un facteur de stimulation intellectuelle. Sous le signe de cette énigmatique incertitude, d’ailleurs, l’amitié entre ces auteurs nous apparaîtra plus riche de sens philosophique.
Symptom Assessment and Management in Patients with Lung Cancer Undergoing Conventional or Traditional Chinese Medicine Care

Patients with lung cancer may experience various symptoms as the disease progresses, which may reduce the benefits of cancer treatment, reduce treatment compliance, delay cancer treatment, reduce the quality of life (QoL), and impact survival. This review discusses comprehensive symptom assessment and management, which are crucial for high-quality lung cancer treatment. Traditional Chinese medicine (TCM) is important in relieving cancer-related symptoms in patients with lung cancer. Including patient-reported outcomes (PROs) in clinical trials and practice can provide a better assessment of symptom burden and the effectiveness of symptom management. Patient-centered care with TCM in lung cancer patients may include six steps: Symptom screening, etiology investigation, comprehensive assessment, integrative management, reassessment, and regular symptom follow-up monitoring. PRO measures can be used to evaluate symptom intensity, the degree to which symptoms interfere with activities of daily living, and the QoL. Clearly defined and reliable PRO measures can enhance patient satisfaction and improve symptom control. Quantitative PRO measures developed from the TCM perspective should be considered one of the important outcome measurements in TCM care. A multidisciplinary collaborative symptom management model, including TCM and conventional therapy, will be the future goal for treating patients with lung cancer.

This study aimed to investigate the incidence of patent processus vaginalis (PPV) in pediatric patients with a unilateral nonpalpable testis and explore the associated factors. From May 2014 to April 2017, 152 boys who were diagnosed with a unilateral nonpalpable testis and underwent laparoscopy in Shanghai Children’s Hospital (Shanghai, China) were included in this study. The data were collected and reviewed, and the results were analyzed regarding the age at operation, side, development, and position of the nonpalpable testis. The mean age of the patients was 2.6 (standard deviation: 2.3) years. The testis was absent in 14 cases, nonviable in 81 cases, and viable in 57 cases. The incidence of PPV was 37.5% (57 of 152) on the ipsilateral side and 16.4% (25 of 152) on the contralateral side. The ipsilateral PPV was more prevalent when the nonpalpable testis occurred on the right side (P < 0.01). Besides, patients with a viable testis had a greater incidence of ipsilateral PPV than those with a nonviable or absent testis (P < 0.01). Moreover, this rate was the highest when the testis was in the abdominal cavity and the lowest when the testis was in the scrotum (both P < 0.01). However, the incidence of contralateral PPV was independent of all the factors. In conclusion, in children with a nonpalpable testis, the incidence of an ipsilateral PPV was significantly related to the side, development, and position of the testis, while it was independent of these factors on the contralateral side.
