Objectives:

The objective of the study is to evaluate plasma homocysteine level and its relation with serum estrogen in pre and postmenopausal women as a risk factor in coronary artery disease (CAD).

Materials and Methods:

A cross-sectional study was conducted among premenopausal (n = 50) and postmenopausal women (n = 50) with an estimation of plasma homocysteine (Hcy) and serum estradiol (E2). Postmenopausal women based on their angiographic status were sub-grouped into A (with normal coronaries) and B (with CAD).

Results:

The levels of Hcy, 21.98 (20.89–24.05) μmol/L, increased significantly (P < 0.0001) and that of E2, 3.05 (2.32–3.6) pg/mL, decreased significantly (P = 0.0001) in the postmenopausal group when compared to Hcy, 6.11 (4.94–8.27) μmol/L and E2, 26.37 (25.3–29) pg/mL in premenopausal group. The levels of Hcy were elevated (24.7 ± 3.92 μmol/L) in postmenopausal Group B in comparison with postmenopausal Group A (21.37 ± 3.31 μmol/L), P = 0.002. Logistic regression analysis showed Hcy and body mass index to be independent predictors of CAD. Plasma Hcy showed an area under curve (AUC) of 1.00 with sensitivity and specificity of 100% at cutoff >12.6 μmol/L between pre and postmenopausal groups and AUC of 0.722 with 60% sensitivity and 84% specificity at cutoff >23.7 μmol/L between postmenopausal Groups A and B.

Conclusion:

We observed low E2 and high Hcy levels in postmenopausal women in comparison with premenopausal women. Among postmenopausal women, those with CAD had higher Hcy levels. Assessing Hcy levels routinely in postmenopausal women will help in better risk prediction of CAD and may also help in conjunction with other risk factors to decide the initiation of hormone replacement therapy.

Authors: Tanaka Masahiro , Kuge Atsushi , Saito Ryozo , Sasaki Kosuke , Yamaki Tetsu , Kondo Rei , Sonoda Yukihiko
Published: May 2024

Background:

Arteriovenous fistulas (AVFs) of the craniocervical junction (CCJ) and intradural AVFs are often associated with aneurysms and varics, and it is sometimes difficult to identify the ruptured point on radiological images. We report a case in which vessel wall magnetic resonance image (VW-MRI) was useful for identifying the ruptured point at the CCJ AVF.

Case Description:

A 70-year-old man presented with a sudden onset of headache. He had Glasgow Coma Scale E4V5M6, world federation of neurosurgical societies (WFNS) Grade I. Fisher group 3 subarachnoid hemorrhage and hydrocephalus were found on head computed tomography. Cerebral angiography showed a spinal AVF at the C1 level of the cervical spine. Magnetic resonance image-enhanced motion sensitized driven equilibrium (MSDE-method showed an enhancing effect in part of the AVF draining vein, but the vascular architecture of this lesion was indeterminate. We performed continuous ventricular drainage for acute hydrocephalus and antihypertensive treatment. Cerebral angiography was performed 30days after the onset of the disease, and was revealed an aneurysmal structure in a portion of the AVF draining vein, which VW-MRI initially enhanced. On the 38thday after onset, he underwent direct surgery to occlude the AV fistula and dissect the aneurysmal structure. Histopathology showed that the aneurysmal structure was varices with lymphocytic infiltration, and hemosiderin deposition was observed near the varices.

Conclusion:

Recently, VW-MRI has been reported to show an association between the enhancement of varices in dural AVF and rupture cases. VW-MRI, especially the enhanced MSDE method, may be useful in estimating the ruptured point in arteriovenous shunt disease.
Intramedullary spinal cord abscess as postoperative complication: A case report
Authors: Valeri Amber Lynn , Alayli Adam , Gordon Jonah , Lockard Gavin , Tran Nam D.
Published: May 2024

Background:

Intramedullary spinal cord abscesses (ISCA) can result in high morbidity and mortality if not treated in a timely manner. The incidence and outcomes of postsurgical ISCA are unknown. We present a case of a 52-year-old male patient with neurofibromatosis type 1 who developed an intramedullary spinal cord abscess after a previous resection of a cervical intradural, extramedullary neurofibroma.

Case Description:

A 52-year-old male with a history of neurofibromatosis type 1 had previously undergone multiple resections of cervical intradural, extramedullary neurofibromas with internal stabilization. Sixteen months after his initial surgery, he developed acute-onset interscapular pain with bilateral lower extremity pain and left hemi-body weakness. Magnetic resonance imaging (MRI) of the cervical spine demonstrated an enlarging contrast-enhancing intramedullary lesion. Surgical exploration and evacuation of the lesion were completed. Intramedullary cultures confirmed a Serratia marcescens abscess. After abscess evacuation and intravenous antibiotics, the patient’s symptoms resolved.

Conclusion:

Given the potential for permanent neurologic damage and loss of independence with intramedullary spinal cord abscess, we advocate that clinicians maintain a high index of suspicion in the postsurgical patient. Diagnostic imaging through contrasted MRI or computed tomography myelogram should be obtained, and prompt intervention, including evacuation and/or antibiotics, should be implemented for the best chance of a favorable outcome.

Chemically Accurate Singlet-Triplet Gaps of Arylcarbenes from Local Hybrid Density Functionals
Authors: Grotjahn Robin , Purnomo Justin , Jin Dayun , Lutfi Nicolas , Furche Filipp
Published: May 2024

Singlet-triplet (ST) gaps are key descriptors of carbenes, because their properties and reactivity are strongly spin-dependent. However, the theoretical prediction of ST gaps is challenging and generally thought to require elaborate correlated wavefunction methods or double-hybrid density functionals. By evaluating two recent test sets of arylcarbenes (AC12 and AC18), we show that local hybrid functionals based on the "common t" local mixing function (LMF) model achieve mean absolute errors below 1 kcal/mol at a computational cost only slightly higher than that of global hybrid functionals. An analysis of correlation contributions to the ST gaps suggests that the accuracy of the common t-LMF model is mainly due to an improved description of nondynamical correlation which, unlike exchange, is not additive in each spin-channel. Although spin-nonadditivity can be achieved using the local spin polarization alone, the using the "common", i.e., spin-unresolved, iso-orbital indicator t for constructing the LMF is found to be critical for consistent accuracy in ST gaps of arylcarbenes. The results support the view of LHs as vehicles to improve the description of nondynamical correlation rather than sophisticated exchange mixing approaches.
Selective and efficient detoxification of sulfur mustard gas analogues with H2O2 using bioinspired Mo and W dithiolene catalysts
Authors: Tanriover Beria , Subasinghe S. M. Supundrika , Mankad Neal
Published: May 2024

Efficient and selective decomposition of chemical warfare agents (CWAs) is immensely important to cope with threats from accidental or intentional releases from stockpiles. One of the most stockpiled CWAs is sulfur mustard (SM) gas. The most effective way to detoxify stockpiled SM is to oxidize the thioether functionality to its benign sulfoxide (SMO) state. However, overoxidation to the corresponding sulfone (SMO2), itself a potent toxin, should be avoided. Thus, cat-alysts for SM detoxification must be precisely tuned to promote the sluggish oxidation of SM while avoiding overoxi-dation of SMO to SMO2. In this study, Mo and W dithiolene catalysts, [MO2(dithiolene)2]2- (M = Mo or W), inspired by the active site structures of oxotransferase enzymes such as DMSO reductase were used as catalysts for oxidation of the SM research analogue, 2-chloroethyl ethyl sulfide (CEES), with aqueous H2O2 as a green oxidant. Under optimized conditions, [WO2(mnt)2]2- and [MoO2(bdt)2]2- (mnt = maleonitriledithiolate, bdt = 1,2-benzenedithiolate) were found to promote selective CEES oxidation to sulfoxide CEESO without overoxidation to sulfone CEESO2 in as little as 5-15 min with catalyst loadings as low as 0.015 mol%. The W catalyst was also found to be reusable without measurable loss of activity. Experimental and computational studies indicate the involvement of 𝜂2-peroxo species, [M(O)(𝜂2-O2)(dithiolene)2]2-, as the active oxidants formed in situ. Overall, the bioinspired catalysts in this study are shown to be promising candidates for developing convenient, inexpensive, efficient, and selective mustard gas detoxification technologies.
Communication: Efficient Approximate Screening Techniques for Integrals over London Atomic Orbitals
Authors: Blaschke Simon , Stopkowicz Stella , Pausch Ansgar
Published: May 2024

Efficient integral screening techniques are essential for the investigation of extended molecular structures. This work presents a critical assessment of well-established approximate screening techniques and extends them for integrals over London atomic orbitals, which are required in the presence of strong, external magnetic fields. Through the examination of helium clusters in such extreme environments, we demonstrate that seemingly straightforward extensions of field-free screening techniques as proposed in recent literature can lead to significant errors. To rectify this, we propose an enhanced screening technique that leads to the desired speedups while still displaying a well-contained error control.

Avoiding lithium dendrites at the lithium/ceramic electrolyte interface and as a result avoiding cell short-circuit when plating at practical current densities remains a significant challenge for all-solid-state batteries. Typically, values are limited to around 1 mA cm-2, even, for example, for garnets with a relative density of >99%. It is not obvious that simply densifying ceramic electrolytes will deliver high plating currents. Here we show that plating currents of 9 mA cm-2 can be achieved without dendrite formation, by densifying Argyrodite, Li6PS5Cl, to 99%. Changes in the microstructure of Li6PS5Cl on densification from 83 to 99% were determined by FIB-SEM tomography and used to calculate their effect on the critical current density (CCD). Not all changes in microstructure with densification act to increase CCD. While smaller pores and shorter cracks increase CCD, lower pore population and narrower cracks act to decrease CCD. Calculations show that the former changes dominate over the latter, predicating an overall increase in CCD, as observed experimentally.
Intermetallic particles distribution in 7XXX series aluminium alloy substrate impacts cathodic stability of silicate sealed anodized oxide
Authors: Raffin Florian , Magnan Maxime , Seyeux Antoine , Zanna Sandrine , Echouard Jaques , Światowska Jolanta , Volovitch Polina
Published: May 2024

A silicate sealing on two tartaric sulphuric acid anodized 7XXX-series aluminium alloys was studied. SEM-EDS, XPS, ToF-SIMS, GDOES, and Raman spectroscopy demonstrated similar morphology and chemical composition of all the sealed layers. Electrochemistry coupled with time-lapse microscopy evidenced that the layers, although stable under anodic polarization, demonstrated localized pitting of the oxide under cathodic polarization in Cl-containing electrolyte. No chemical or morphological surface modification was detected outside of the pits. The number and size of the pits depended on the IMPs distribution in the alloy, buried under 6 µm thick oxide. A degradation mechanism explaining these observations was proposed.
An atomistic picture on build-up and degradation reactions in area-selective atomic layer deposition with a small molecule inhibitor
Authors: Wellmann Paul Philipp , Pieck Fabian , Tonner-Zech Ralf
Published: May 2024

We investigate the blocking layer formation of the trimethoxypropylsilane small molecule inhibi-tor (SMI), its blocking mechanisms, and all relevant blocking layer disintegration reactions on SiO2 in the area-selective atomic layer deposition of Al2O3 with density functional theory-based methods. The choice of amorphous silica (a-SiO2) surface models proves essential to obtain the correct SMI chemistry. We demonstrate that complete blocking of reactive sites is possible here and deduce an upper SMI density limit of the resulting blocking layer which is limited by Pauli repulsion. The SMI adsorption process can nevertheless leave unreacted silanol groups, which could be remedied by using a second monodentate SMI. The SMI layer is neither inert against common aluminum precursors nor the co-reactant water as our comprehensive analysis of the var-ious blocking layer disintegration reactions for different SMI layer densities shows. We report a new blocking mechanism of the SMI layer and propose to differentiate what is discussed as the ‘steric blocking’ effect into the known ‘adsorption prevention’ and the newly found ‘reactivity reduction’ effects. For trimethylaluminum (TMA) an additional favorable SMI layer decomposi-tion mechanism is found compared to the bulkier triethylaluminum (TEA) which could explain the lower selectivity of TMA found experimentally. Our computational work offers some princi-ples and ideas for future experiments to improve selectivity in AS-ALD processes.
Total Synthesis Facilitates in vitro Reconstitution of SgvP, the C–S Bond Forming P450 in Griseoviridin Biosynthesis
Authors: Stout Carter , Renata Hans
Published: May 2024

Griseoviridin is a group A streptogramin natural product from Streptomyces with broad-spectrum antibacterial activity. A hybrid polyketide-non-ribosomal peptide, it comprises a 23-membered macrocycle, an embedded oxazole motif, and a macro-lactone with a unique ene-thiol linkage Recent analysis of the griseoviridin biosynthetic gene cluster implicated SgvP, a cytochrome P450 monooxygenase, in late-stage installation of the critical C–S bond. While genetic and crystallographic experiments provided indirect evidence to support this hypothesis, the exact function of SgvP has never been confirmed bio-chemically. Herein, we report a convergent total synthesis of pre-griseoviridin, the putative substrate of P450 SgvP and precursor to griseoviridin. Our strategy features concise and rapid assembly of two fragments joined via sequential peptide coupling and Stille macrocyclization. Access to pre-griseoviridin then enabled in vitro validation of SgvP as the C–S bond forming P450 during griseoviridin biosynthesis, culminating in a 9-step chemoenzymatic synthesis of griseoviridin.

We disclose a new platform for C(sp3)-directed C–H annulations to generate valuable heterocycles from readily available starting materials. A commercially available one carbon linchpin is leveraged to access alkyl boron species from simple anilines. Rhodium-catalyzed C(sp3) transmetallation from this key intermediate provides a C–Rh bond appropriately positioned for ortho-C–H activation, enabling formation of C,C-rhodacycles. With the addition of a variety of alkyne coupling partners, diverse dihydroquinolines are synthesized.
Distinguishing Potential Organic Biosignatures on Ocean Worlds from Abiotic Geochemical Products using Thermodynamic Calculations
Authors: Robare Jordyn , Shock Everett
Published: May 2024

The search for life in our solar system often involves efforts to detect organic molecules, which have been found on many extraterrestrial bodies, including planets, moons, meteorites, comets, and asteroids. These chemical signatures are not typically thought of as biosignatures because we know that organic synthesis can occur through abiotic processes. Therefore, development of methods for distinguishing biotic and abiotic biosignatures would enable interpretation of data collected from habitability and life-detection missions. Life on Earth harnesses energy-releasing reactions to power biosynthesis reactions, which often require energy. Using thermodynamic data, we can quantify the energy required for organic synthesis. If an organic molecule is detected in an abundance that is thermodynamically unstable, then it is possible that life coupled its synthesis to other energy-releasing reactions. On the other hand, if an organic molecule is detected in an abundance that is thermodynamically stable, then abiotic synthesis was plausible. This sorting framework can be applied to the search for life wherever we have geochemical data. One such example is Saturn’s moon Enceladus. Small compounds involving the elements that comprise the majority of biomass were detected by the Cassini spacecraft in the plume gas erupting from the subsurface ocean. Using Enceladus as an example, we demonstrate the utility of thermodynamic calculations for distinguishing biosignatures and show that organic synthesis is often favorable using the carbon sources available on Enceladus. While these results may lead us to conclude that hypothetical organic signatures on Enceladus are abiotic, this framework can be applied to other environments in the search for genuine biosignatures.
Exploring essential soft skills for maximizing employability of english graduates in Bangladesh
Authors: Robiul Islam , Happy Kumar Das
Published: May 2024

Soft skills, absolute knowledge, various skills, positive attitudes, values, beliefs, and habit are vital for graduates' professional, social, and personal success. Many graduate and postgraduate students struggle to adapt their learning to their daily lives and work. Thus, Bangladeshi graduates face substantial unemployment. Knowing and practicing soft skills during school helps them meet workplace needs. Therefore, soft skills training must be included in the curriculum to help students use soft skills gleaned from English literature in real life. This study assesses the soft skills needed for employment by English graduates of tertiary colleges affiliated with Bangladesh's National University (NU). The study reviewed national and international government documents, published and unpublished studies, online resources, and researchers' experiences and observations. The outcomes were categorized thematically to determine the most essential soft skills for English graduates' employability. Finally, drawing from lessons learned from national and international perspectives, some policy gaps have been explored in Bangladesh, and some policy suggestions have been made to implement soft skills training in the curriculum of English language and literature courses at NU-affiliated colleges. The findings suggest studying instructional methodologies, classroom management, question sets, teacher preparation, assessment systems, soft skills instruction, mentorship, and counseling. After reviewing the literature, the researcher finds that English graduates need 49 sub-skills in twelve soft skills: Communications, interpersonal, self-management, people management, collaboration, emotional intelligence, time management, problem-solving, decision-making, critical thinking, leadership, and creativity. Upon evaluating the literature, the study found that while soft skills can be improved in the English curriculum, the instruction for implementation is unclear.
Influence of Online Gaming on Behavior of Gamers in Pakistan
Authors: Bano Syeda Ammarah , Zaheer Lubna , Hameed Nasir , Hussain Jam Sajjad
Published: May 2024

This study reveals that online video games have emerged as a novel platform for social interaction, wherein numerous gaming options facilitate player’s competition and collective interaction within the virtual realm. Gamers have increasingly begun to form distinct virtual social communities due to the inherent capacity of these games to facilitate social networking in a multiplayer online setting. This phenomenon has given rise to a unique social dynamic among video game enthusiasts. The present study delves into an exploration of the social gaming behaviour exhibited by participants engaged in multiplayer online games. Additionally, it seeks to establish a correlation between virtual and real-world behaviours by examining the relationship between destructive and constructive social behaviours and the dominance and affiliation dimensions of social interaction. 
Purpose: Online gaming has become a unique phenomenon among the young players with a significant influence on them. The basic objective of this study was to determine the social interaction caused by online gaming among young game players. This study conducted in Pakistani perspective has achieved the objections set to analyze the influence of online gaming and increased level of social interaction. 
Design/Methodology/Approach: To conduct this investigation, an online survey was administered to individuals who regularly engage in multiplayer gaming activities and dedicate a substantial portion of their daily time to gaming. The study sample consisted of 200 gamers spanning an age range of 16 to 30 years.
Findings: The results of this inquiry shed light on the prevalence of pro-social behaviour and anti-social behaviour, characterized by constructive and destructive actions among gamers, respectively. Furthermore, the study reveals that destructive behaviour negatively predicts affiliation, while constructive behaviour has a positive predictive influence on affiliation. Moreover, certain demographic variables, such as age and gender, exert a significant impact on the prediction of dominance within the gaming community. The findings of this study provide substantial support for the notion that virtual social interactions have a notable influence on real-world behaviours, underscoring the interconnectedness between the online gaming environment and broader social dynamics.
Implications/Originality/Value: Online gaming has become a common practice not only among young adults but also among the minors. Thus, this phenomenon has reduced physical activities among the youth and even among the school going children. This study may provide an insight into the matter and possible appropriate recommendations as well.
STRUCTURAL DIVERSITY OF OCTA- AND HEXADECAFLUORINATED TIN (II) AND TIN (IV) PHTHALOCYANINES
Authors: Klyamer D. D. , Sukhikh A. S. , Bonegardt D. V. , Asanov I. P. , Basova T. V.
Published: May 2024

In this work crystal structures of octa- and hexadecafluoro-substituted tin(II) and tin(IV) phthalocyanines are shown. Complexes were obtained by fusing of fluorinated phthalonitriles with SnCl2 (Method 1) and refluxing the initial reagents in 1-chloronaphthalene (Method 2). In the case of octafluorosubstituted tin complexes it has been shown that during synthesis by the Method 1, Sn(II)PcF8 complexes are formed. At the same time, during the synthesis by the Method 2, Sn(IV)Cl2PcF8 complexes are obtained. It was demonstrated that not only the synthesis method but also the number of fluorine substituents affects the composition and structure of the obtained complexes. Unlike octasubstituted derivatives, only tin(IV) complexes are formed during the synthesis of hexadecafluorosubstituted phthalocyanines using both methods. Thus, when fusing tetrafluorophthalonitrile with SnCl2, halogen atoms are exchanged and a mixture of monomeric SnF2(PcF15Cl) and dimeric Sn2F3(PcF15Cl)2 complexes is formed. The synthesis in solution leads to the formation of SnCl2PcF16, which crystallizes together with 1-chloronapthalene solvate molecules. The effect of heating and vacuum sublimation on the transformation of Sn(IV) phthalocyanines is also studied.

Creation and Promotion of Ukraine’s Nation Brandingas a PR Tool of Public Administration
Authors: Morozova Olena
Published: May 2024

The article considers the main theoretical aspects of the creation of Ukraine’s nation branding. The construction and development of a nation branding as a PR tool used in public administration is analysed. It is noted that the promotion of Ukrainian national interests is a strategic investment in the future. The success of economic growth and the dynamic development of relations with other states largely depend on how the brand of the state is formed and promoted in the Ukrainian and world markets.
It is emphasised that the transformation and popularisation of the Ukraine’s nation brand should meet the challenges of the time, be coordinated and purposeful. In particular, it is necessary to establish cooperation between the public and private sectors, including representatives of the business community, culture, education, and mass media since
the nation branding is also intrusted with the task of countermeasures against Russian disinformation for Ukrainian and foreign audiences in the situation of military aggression by Russia. The greater there is trust in the brand of Ukraine as the state, the higher there is trust in the information that is produced by both governmental and non-governmental organisations in Ukraine.
The article points out that today Ukraine has much more opportunities for direct and effective communication with Western audiences. Meaningful and emotional speeches of the President of Ukraine at parliamentary platforms in different countries of the world give representatives of the elite and the general public a fairly objective picture of what is happening in Ukraine. Perhaps for the first time in the history of Ukrainian independence, the way Ukraine is perceived by Western consumers, is determined by objective reality, not by Russian narratives.

The scientific understanding of the narratives of media enlightenment of the modern theory of liberal culture and the factor of functioning of its carriers in the conditions of historical and contemporary aspects of the communication transformation of society is a relevant and undeniable fact of the modern science of social communications. The description of the theory of liberal information culture from the point of view of typology and the principles of identifying the primary and fundamental nature of the fact and the possibility of its free interpretation in the realization of the interpretive resources of the carriers of information culture, which forms a specific feature of liberalism in their totality — free personal social evaluation. Despite several centuries of actual spread within the global information environment, liberalism (both as a philosophical trend, theoretical current, and informational practice) stands in a certain way aside from serious research in social communications. Modern mass communication, increasingly clearly and unequivocally drawing the border between the demonstration characteristics of a communication product based on the principle of online or offline, leaves both severe topics and problems, as well as the seriousness of approaches to their coverage, out of the context of the audience’s attention. The study aims to reveal the key factors of the modern and historical aspects of the carriers of Ukrainian liberal information culture. Following the purpose of the research, we defined the following tasks: to find out the content and audience characteristics of social communications as the basic concepts of the functioning of liberal information culture. The methodological basis of the research is a combination of general scientific methods and particular methods and approaches to the study of regularities and features of information processes and phenomena. As for the comprehensive system of scientists in the theoretical component of the research on Ukrainian information culture of the second half of the 19th — beginning of the 20th century, this approach leaves out of the research field two popular opposite paradigms of information culture: the so-called Modern project and the Postmodern project. Accordingly, the research results are specific general ontological grounds for the universal unity of things, people, events, and reports about them, hence — universal criteria for evaluation and interpretation of everything. In this understanding, the informational and cultural world is a universe of all possible meanings, contents, and guidelines of human existence, transmitted to a person at any time and space.
American Humorous Discourse. Manipulation Strategy
Authors: Kharchenko Oleg
Published: May 2024

The conducted research shows that the communicative strategy of manipulation is widespread in the American humorous discourse. The communicative strategy of manipulation can be implemented through the tactic of ambiguity, the tactic of faulty logic, the tactic of comic lies, and the tactic of restraint.This can be implemented through ambiguity tactics and different types of ambiguous communicative acts that use the following variants of double meaning: «Feghoot», «hurricane of puns», «Stealth», «double entendre», «innocent innuendo», «accidental innuendo», «double meaning with clarification», «Lampshaded double entendre» etc. At least in part, they are based on such a cognitive pattern as «Von Restorff» or «Extraordinarity». Modernity is characterized by the process of nomination and standardization of American terminology, which is used for American literature, literary journalism, and cinema, while it actively penetrates into multimedia content around the world.

Son zamanlarda Zeydiyye’ye dair gerek şahıs ve eser, gerekse tarih, yorum ve literatür eksenli çalışmaların dini ilimlerin hemen her bir sahasında kendisini göstermeye başladığı görülmektedir. Türk akademyasının söz konusu geleneği çeşitli yönleriyle ele alması memnuniyet verici bir gelişme olarak görülebilirse de bu doğrultudaki araştırmaların bir yekûn olarak sonraki çalışmalara fikrî kaynaklık teşkil edecek olması, söz konusu çalışmaları daha da önemli hale getirmektedir. Kadir Demirci’nin Zeydiyye’nin hadis anlayışına hasrettiği eseri, bu bakımdan oldukça önemli bir konuma
sahiptir. Yazarın Zeydiyye ve Hadis başlıklı çalışmasını çeşitli yönlerden ele alan bu tanıtım yazısı, eserin zati kıymetini ilgililerle ve özellikle de hadis akademyası ile paylaşmayı hedeflemektedir. Şiî
geleneğin bir kolu olan Zeydiyye, Zeyd b. Ali’nin (ö. 122/740) isyanı sonrası ona mensubiyetin siyasî bir tezahürü olarak ortaya çıkmış, Kâsım er-Ressî (ö. 246/860) ile fikrî ve itikadî yapıya kavuşmaya başlamış, Yahyâ b. Hüseyin (ö. 298/911) ile kurumsal kimlik kazanarak müstakil bir oluşum haline gelmiştir. Zeydiyye İslam kültür ve düşünce geleneği içerisinde zaman zaman inkıtalara rağmen günümüze kadar varlığını sürdürmüş bir mezheptir. Benimsediği görüşler, ortaya koyduğu siyasî tavır ve ürettiği müktesebat ile zengin İslam birikimine birçok sahada kayda değer katkılarda bulunmuştur. Dolayısıyla Müslüman topluluklar açısından diğer farklı/özgün oluşumların da çeşitli yönleriyle incelenerek bizzat kendi kaynaklarından hareketle görüş ve kabullerinin ortaya konulması
önem arz etmektedir. Bu doğrultuda söz konusu mezhebin hadis ve sünnete dair klasik ve modern döneme yansıyan anlayış ve yaklaşımlarını tarihi bir seyir ve bilimsel bir bakış açısıyla ele alan
Zeydiyye ve Hadis adlı eser; ilgi alanı, kapsamı, metodu ve zengin muhtevasıyla dikkati çekmekte ve tanıtımı hak etmektedir.
