Authors: Mays Y. Khamas  , Inas Al-Rawi  , Aseel A. Saleh
Published: April 2021

Objective: This study was based on the evaluation the degree of total occlusal convergence of teeth preparedfor all-ceramic crowns which is the main factor that retention and resistance form of indirect restorationsdepended on. Teeth preparation done by 3rd year dental students at Al-Esraa university collage, Iraq in 2019.Materials and method: Eighty typodont teeth, maxillary central incisor(n=40) and first premolar teeth(n=40) were prepared for all-ceramic crowns by preclinical dental students under examination condition.The prepared teeth were scanned and digitized using the laser scanner 3Shape D710 (SculptCAD, Texas,USA). The datasets were evaluated using inspection software (shaper 3D zrt. Hungary, 2020) that used forthe assessment of the total occlusal convergence. Each tooth was virtually sectioned by four vertical planes:buccopalatal, mesiodistal, mesiobuccal–distopalatal and distobuccal– mesiopalatal and for each plane thetotal occlusal convergence angle (degree) was measured by drawing lines along the two opposing axialwalls from the finish line extended coronally. The data were analyzed with appropriate statistical tests usinganalysis of variance (ANOVA) and unpaired t-tests. Differences between groups were tested for significanceat 95% confidence interval.Results: The results revealed that the students prepared the central incisor teeth with average TOC valuesof 11.46° ± 6.81°, 9.91° ± 4.92°, 10.54° ± 7.05° and 12.06° ± 6.71° respectively, from the buccopalatal,mesiodistal, mesiobuccal–distopalatal and distobuccal– mesiopalatal planes. Concerning first premolarteeth, students prepared them with average TOC values of 12.03° ± 6.63°,11.57° ± 6.34°, 14.3° ± 6.94° and12.55° ± 6.6° respectively.The findings revealed that the approximated average TOC values for all the measured planes weregreater than the optimal TOC range 4 to 6 ° but stayed within the TOC acceptable range 4 to 14 °.Ordinary one-way ANOVA test showed no significant (P >0.05) differences in the average TOC betweenthe different four planes within each tested group of teeth. The average value of overall total occlusalconvergence (TOCs) in the first premolar teeth= 12.61°± 6.63°was higher than for the central incisor teeth=10.99°±6.4°. Unpaired t-test for the two tested groups revealed significant (p < 0.05) differences.Conclusions: The presented study found that about 85%, 65.83% respectively of upper central incisorand first premolar teeth prepared for all-ceramic crowns by pre-clinical dental students with acceptablerecommended convergence angle range 4-14°.

Published: April 2021

Hypertension is a degenerative disease that is often found in conjunction with other degenerative diseases.The study was aimed at analyzing ecologically the factors related to the prevalence of hypertension inIndonesia. The study was conducted using secondary data from the 2018 Indonesia Basic Health Survey.All provinces were taken as samples. Apart from the prevalence of hypertension, 4 other variables analyzedas independent variables were the prevalence of obesity, the percentage of the population with less physicalactivity, the percentage of daily smokers, and the percentage of the population with salty food consumptionhabits ? 1 per day. Data were analyzed using a scatter plot. The results of the study found that the higherthe prevalence of obesity in a province, the higher the prevalence of hypertension in that province. Thehigher the percentage of the population with less physical activity in a province, the higher the prevalenceof hypertension in that province. The higher the percentage of daily smokers in a province, the higher theprevalence of hypertension in that province. The higher the percentage of the population with salty foodconsumption habits ? 1 per day, the higher the prevalence of hypertension in that province. It was concludedthat the four independent variables analyzed ecologically were positively related to the prevalence ofhypertension in Indonesia.

1853-1856 Kırım Harbi’nde Osmanlı - Avusturya İlişkileri
Authors: Bi̇rbudak Togay Seçkin
Published: April 2021

1853-1856 yılları arasında yaşanan Kırım Harbi, başlangıçta Osmanlı Devleti ile Rusya arasında başlayan ancak ilerleyen yıllarda İngiltere, Fransa ve Piyomente'nin de Osmanlı lehine dâhil olduğu bir savaş haline bürünmüştür. Bu süreçte Avrupa'nın diğer önemli güçleri olan Avusturya ve Prusya'nın Osmanlı Devleti ile birlikte savaşa girmemekle birlikte siyaseten Osmanlı Devleti'ne yakın durduklarını söylemek mümkündür. Bilhassa Avusturya, savaş müddetince Rusya'nın barış masasına oturtulması ve makul mütareke şartlarının sağlanabilmesi için girişimlerde bulunmuş, bununla da yetinmeyerek Osmanlı Devleti'nin hâkimiyet alanı içerisinde yer alan ancak savaşın başından itibaren Rus işgali altında bulunan Eflak-Boğdan topraklarının işgalden kurtarılması adına Osmanlı Devleti ile bir ittifak anlaşması imzalayarak Tuna'nın kuzeyindeki mücadeleye dâhil olmuştur. Savaş yıllarında Osmanlı Devleti ile Avusturya arasında kurulan bu yakın siyasi ilişki sayesinde Rusya'nın savaşı devam ettirmek için Avrupa'da müttefik bulma imkânı ortadan kalkmış ve Rusya neredeyse tüm Avrupa ile ya savaş meydanında ya da diplomasi masasında mücadele etmek zorunda kalmıştır. Ayrıca iki ülke arasında imzalanan 14 Haziran 1854 tarihli antlaşma ile savaşın ilk gününden itibaren Rus işgali altına giren Osmanlı Devleti'ne bağlı özerk Eflak ve Boğdan prenslikleri, Rus askerlerinin çekilmesinin ardından Avusturya birlikleri tarafından savaşın sonuna kadar denetim altına alınmıştır. İlaveten Viyana, Kırım Harbi müddetince taraflar arasında yapılan müzakerelerde diplomasi masasının merkezi olmuş, gerek 1853 yılı Temmuz ayında gerekse 1855 yılı Mart ayında mütareke görüşmeleri düzenlenmiştir. Nitekim çatışmalara son verilen 1 Şubat 1856 tarihli protokol de Viyana'da imza edilmiştir. Tüm bu gelişmeler Kırım Harbi süresince Osmanlı Devleti ile Avusturya arasındaki açıktan veya dolaylı siyasi birlikteliğin ana hatları olarak karşımıza çıkmaktadır. Söz konusu çalışma Kırım Harbi yıllarında Osmanlı Devleti ile Avusturya arasındaki ilişkileri ele almaktadır. Bu kapsamda Avusturya yönetiminin Osmanlı-Rus Savaşı'nın başlaması karşısında takınmış olduğu tutum, savaşın sona erdirilmesi adına yapılan girişimler ve Viyana'daki diplomatik temaslar, Tuna'nın kuzeyinde Rus işgaline uğrayan Rumen prensliklerinin kurtarılması adına imzalanan 13 Haziran 1854 tarihli Osmanlı-Avusturya Antlaşması ve bu antlaşmaya bağlı olarak yaşanan gelişmelere değinilmektedir.

Kimisi onu Asya'nın tek kurtarıcısı, yıllar sonra Doğunun Batıya karşı üstünlüğü olarak görürken; kimi de bütün dünyada kan döken bir vahşi şeklinde tanıtıyor. Dolayısıyla bu konularda bugüne kadar binlerce araştırma yapılmakla beraber, biz burada bazı Çingiz-nâmelerin ışığında, Çingiz'in ortaya çıkışıyla, nasıl bir devlet kurduğunu işlemeye çalışacağız. Destansı bir biçimde yazıya geçirilen Çingiz-nâmeleri temel alarak, Çingiz Kagan'ın çocukluk, gençlik ve han olmasına dair bir takım tarihi hadise ve motifleri Türkçe belgelerle de karşılaştırarak, aradaki benzerlikleri ortaya koymaya gayret edeceğiz.
Kıbrıs Hala Sultan Tekkesi Şeyhleri Üzerine Bir Araştırma (1570-1878)
Authors: Demi̇ryürek Mehmet
Published: April 2021

Hz. Peygamberin sütannesinin kardeşi Ümmül Harâm bint-i Milhan el-Ensâriyye'nin türbesi Kıbrıs'ın Larnaka kentindedir. Genellikle kabul edildiğine göre Müslümanların Kıbrıs'a yaptığı ilk sefere katılmış ve Kıbrıs'ı fethetmek için M. 649 yılı ilkbaharında kocası Ubada ibn-as-Samit ile birlikte Suriye'den ayrılmıştır. Ordu Kıbrıs'a çıktığı zaman bindiği katırdan düşerek gömülü olduğu yerde vefat etmiştir. Osmanlıların Kıbrıs'ı fethinin ardından, mezarının bulunduğu yere ayrı bir önem verilmiş, bazı mülkler onun türbesi için vakfedilmiş ve türbenin muhafazası için türbedarlar tayin edilmiştir. Söz konusu türbenin Osmanlı öncesi dönemde inşa edilip edilmediği kesin olarak bilinmese de türbenin ve türbedarların Osmanlı döneminde ve 17. yüzyılın ilk yıllarından itibaren var olduğu anlaşılmaktadır. Kıbrıs Türklerinin "Hala Sultan Tekkesi" olarak andığı türbe bugün de varlığını ve kutsallığını sürdürmektedir. Bununla birlikte Osmanlı döneminde Hala Sultan Tekkesinin şeyhleri hakkında yapılmış kapsamlı bir araştırma bulunmamaktadır. Bu nedenle çalışmanın amacı, adanın Osmanlı yönetiminde bulunduğu dönemde (1570-1878) türbede/tekkede görev yapan şeyhleri tespit etmek ve tekkenin/türbenin tarihinin aydınlatılmasına katkıda bulunmaktır. Vakıflar Genel Müdürlüğü Arşivi ile Başbakanlık Osmanlı Arşivi belgeleri ve Kıbrıs Şer'iye Sicilleri bu çalışmanın temel kaynakları olacaktır.
The Evaluation of Some Claims of Western Travelers and Researchers about the Crypto-Christions in Trabzon (Trebizond) and its Vicinity in the XIX. Century
Authors: Kuş Ayşegül
Published: April 2021

XXIX. century is the period through which the Ottoman State radically went some military, admnistrative, social, cultural and economic changes. Especially, when the Tanzimat was declared in 1839, non-muslims were granted some rights such as the guarantee of life, honor and property of the subjects, the equal status between the Muslims and the non-muslims and the equality before the law. Thus, in the course of time following the Tanzimat and the Islahat Edicts, some changes took place in the social, political, economic lives of both Muslims and non-muslims. Even though some had the Muslim identity, they practiced deception and retained their old faiths and rites. Paralel to the emergence of some political, social and edonomic changes peculiar to the XIX. century, when they were granted some rights, they felt more secure under the wings of the Western powers. Subsequently, some of them declared that they are not Muslims and this time they wanted to benefi t from the advantages of being a Chrtistian. As in the case of Kurumlis living in the north of Gümüşhan in the Trabzon (Trebizon) Povince, some goups offi cially registered as Muslims openly started to declare that they are not Muslims and demanded to convert to their own faith especially following the Islahat Edict (1856) . The purpose of this study is to use the accounts of some Western travelers and researchers who came to Trabzon in the XIX. century and analyze, question and evaluate their opinions about the existence of the Crypto-Christians living in Trabzon and in its vicinity.

Osmanlı Devleti’nde Nüzul Vergisinin Teşkili ve Gelişimi: XVI-XVII. Yüzyıllarda Osmanlı Ekonomisini Nüzul Vergisi Üzerinden Değerlendirmek
Authors: Polat Süleyman
Published: April 2021

Osmanlı Devleti'nde sefer ihtiyaçlarını karşılamak için zaman içerisinde çeşitli vergiler uygulamaya konulmuştur. Bunların en bilineli ve en eskisi avarız vergisidir. Literatürdeki bilgilere göre, Osmanlı Devleti'nde avarız vergisinin sefer ihtiyaçlarının karşılanmasında yetersiz kalmasının ardından, nüzul vergisi alınmaya başlanmıştır. Bu kapsamda nüzul vergisi avarız türü vergilerin ilk örneklerinden olması dolayısıyla önemlidir. Ancak bu verginin hangi koşullarda, hangi zaman diliminde Osmanlı Devleti tarafından uygulanmaya başlandığı konusunda verilen bilgiler ya güncel değildir ya da tutarsızlıklar içermektedir. Bu çerçevede yapılan çalışmada -arşiv belgeleri kullanılarak- nüzul vergisinin Osmanlı vergi sistemi içerisinde gelişiminin tespiti aranacak, verginin hangi tarihte nasıl tarh ve tahsil edildiği belirlenmeye çalışılacaktır. Ayrıca bu tespitler ortaya konulduktan sonra verginin gelişimi Osmanlı askerî-malî ve ekonomi tarihi içerisinde değerlendirilecektir.
Leading through COVID-19: understanding and supporting grief and loss
Authors: Kutanzi Ethan , Fraser Kathleen , Wirtzfeld Debrah
Published: April 2021

The COVID-19 pandemic has created an environment in which grief and loss are being experienced collectively. This grief can lead to increased burnout, decreased productivity, and increased likelihood of job turnover. With health care workers already facing increased risks because of their frontline pandemic responsibilities, it is important to provide leaders with knowledge and tools to support their grieving team members. Understanding the Kübler-Ross grief model, as well as grief-related concepts such as anticipatory grief, disenfranchised grief, moral injury, and complicated grief, will help leaders provide normalizing support. This approach may include building and fostering trusting relationships, engaging in self-reflection, participating in supportive conversations, and, when appropriate, sharing information around grief-support resources. There is no universal timeline for the resolution of grief; mental health impacts can last for many months and can continue to resurface for years. During the COVID-19 pandemic, we educated health care workers around the issues of grief and loss by focusing on the relationship side of the Wheel of Change, interviewing people with expertise in the area, holding town hall meetings, and hosting online “coffee and chat” sessions for physicians. We recommend relying less on policy development and, instead, focus on strengthening workplace relationships and creating opportunities for connection and discussions.

Quand Emmanuel Macron veut réparer le lien entre l’Eglise et l’Etat. La question de l’autorité dans les commentaires YouTube
Authors: Gern Laetitia
Published: April 2021

La déclaration controversée du Président de la République Emmanuel Macron au sujet de la réparation du lien entre l’Église et l’État nous offre un cas d’analyse spécifique dans lequel le rapport à l’autorité est débattu. L’article montre que la question de la déconstruction de l’autorité dans l’espace des commentaires sur YouTube passe par la mobilisation de l’argument par l’absurde et par des attaques personnelles telles que l’insulte ou la dérision. Ainsi, les internautes opposés aux dires d’Emmanuel Macron décrédibilisent son autorité et vont jusqu’à mettre en cause sa légitimité à exercer le pouvoir. De leur côté, les internautes favorables à la restauration du lien reconfigurent le discours controversé en s’appuyant sur la loi de 1905 et font appel à l’ensemble de la communauté YouTube. En utilisant les fonctionnalités technodiscursives de la plateforme, les internautes participent au débat et se confèrent une autorité de commentateurs politiques.
Entre déjà-dit et jamais-dit. Cancers rares et quêtes d’autorité numérique
Authors: Charbonneaux Juliette , Berthelot-Guiet Karine
Published: April 2021

Cet article propose d’interroger la notion de « parent expert » autour de l’analyse de discours numériques portant sur un cancer bien particulier : le glioblastome. Il s’agit d’un cancer rare et peu connu qui, au moment du diagnostic, est souvent très avancé avec un pronostic sombre et des atteintes neurologiques déjà handicapantes. De ce fait, il s’avère que ce sont avant tout des proches qui s’expriment à son sujet au sein des « forums de patients ». Ainsi, cette contribution propose-t-elle de traiter les questions suivantes : comment les discours numériques relatifs au glioblastome font-ils apparaître la construction, par ces parents proches, de figures et positions d’autorité ? Dans quelle mesure leur quête d’autorité en ligne s’articule-t-elle à une prétention à s’affranchir du « déjà-dit » de l’institution médicale, notamment, en revendiquant du « jamais dit » ? À partir de l’analyse sémio-discursive des récits et discours tissés dans l’espace numérique d’un corpus de forums francophones dédiés, l’article montre comment les participants se positionnent par rapport aux acteurs évoqués et en viennent à produire eux-mêmes des formulations d’autorité qui s’articulent à l’expertise.
La polémique autour des « délits de la pensée » dans le contexte de l’autoritarisme vietnamien : un processus de démocratisation ?
Authors: Nguyen-Pochan Thi Thanh Phuong
Published: April 2021

Par le biais d’une analyse de la polémique autour des accusations d’« auto-transformation » et d’« auto-évolution », formulées par le Parti communiste vietnamien (PCV) à l’encontre de Chu Hảo - un intellectuel-membre du PCV, cet article cherche à vérifier l’hypothèse selon laquelle la polémique rendrait possible une coexistence dans le dissensus et démocratiserait ainsi l’espace public en régime autoritaire. Notre analyse s’appuiera sur un corpus constitué des occurrences d’information couvrant cette affaire pendant les trois derniers mois de 2018 et qui sont issues de deux sources : onze occurrences issues des médias officiels de l’État et du PCV et 23 occurrences issus des médias et réseaux sociaux sur Internet. Nous éclaircirons les procédures de polarisation et le processus dialogique qui organisent la coprésence des discours antagonistes dans l’espace public, mais aussi la fracture issue du camp des intellectuels contestataires.
La polémique autour de bonjour/hi sur le web : vers la déconstruction du discours d’autorité
Authors: Molinari Chiara , Barbeau Geneviève Bernard
Published: April 2021

En novembre 2019, Simon Jolin-Barrette, ministre québécois responsable de la langue française, revient sur une polémique qui avait eu lieu deux ans auparavant et qui portait sur la formule de salutation bilingue bonjour/hi, employée dans les commerces montréalais et considérée par certains comme signe du déclin du français au Québec. Le ministre déclare avoir l’intention d’interdire cette formule au profit du rituel français de salutation bonjour. Or, dans un contexte sociolinguistique comme celui du Québec, une telle affirmation ne peut passer inaperçue et une nouvelle polémique éclate. Notre objectif est de montrer comment les réactions suscitées – dans l’arène politique et les médias, mais surtout au sein de la population s’exprimant en ligne – ont contribué à la déconstruction du discours du ministre et à son incapacité à s’imposer comme discours d’autorité. Notre attention porte principalement sur les modalités (techno)discursives au moyen desquelles les participants aux échanges affaiblissent, voire nient, l’autorité du ministre.
Comparative Studies on Medium Carbon Low Alloy Steels and Maraging Steels
Authors: Kumar Nikhil , Ramesha C.M. , Anilkumar T. , Rajendra P. , Chandan B.R.
Published: April 2021

The maraging steel are considered ultra-high strength due to its yield strength greater than 1400Mpa and are part of a set of advanced materials of interest for technological development, mainly for aeronautics and aerospace industry. For this purpose they should exhibit good toughness, fatigue resistance and acceptable weldability. Since the maraging steels are of higher cost we are intended to make the Medium Carbon Low Alloy Steel (MCLA) for the purpose of aeronautical and aerospace industry instead of Maraging steel as the cost of MCLA is comparatively less. An attempt is made to study on the basic properties of MCLA steels and Maraging steels by process modifications and comparing the results with that of the standard properties of the Maraging steel.
Effect of Oxygen Flow Rate on Surface Morphology and Optical Properties of Reactive DC Magnetron Sputtered TiO2 Thin Films
Authors: Lavanya Mekala , Ratnam Srirangam Sunita , Borra Rajesh Kumar , Thota Subba Rao
Published: April 2021

In the present work, reactive DC magnetron sputtering method is used to deposit TiO2 thin films on glass substrates. The structural, surface morphology and optical studies of TiO2 thin films were discussed by varying the oxygen flow rates from 1 to 4 sccm. X-ray diffraction patterns of TiO2 thin films show amorphous nature. The surface morphological and elemental composition of TiO2 thin films were examined by field emission scanning electron microscopy and energy dispersive X-ray spectroscopy. From the optical absorption spectra, the shifting of absorption edge towards the longer wavelength leads to the decrement of optical bandgap from 3.48 to 3.19 eV with an increase of oxygen flow rate from 1 to 4 sccm.
Relationship between the Different Amount of LMZBS Glass and Dielectric Properties of Li2(Mg0.96Ni0.04)SiO4 Ceramics
Authors: Peng Rui , Li Yuan Xun , Su Hua , Lu Yong Cheng , Wang Xue Ying , Gan Gong Wen , Wang Gang
Published: April 2021

The effect of different amount of LMZBS glass on the sintering behavior, microstructure and microwave dielectric properties of the Li2(Mg0.96Ni0.04)SiO4 ceramics was investigated. The synthesis of materials was based on the solid-state reaction method. The micromorphology of the composite ceramics was confirmed using scanning electron microscopy. The microwave dielectric parameters were measured by the network analyzer. The mechanism of heat transfer coming from LMZBS glass lower the densification temperature of matrix ceramic from 1150°C down to 900°C. Excellent microwave dielectric properties were obtained with 1.2 wt% LMZBS glass sintered at 900°C for 4h (εr=5.77 and Q×f=29,558 GHz at 16 GHz, τf=-14.5 ppm/°C). There was a compatibility between the composite ceramic and Ag. Therefore, the aimed ceramic has great potential value of application in the field of low temperature co-fired ceramics of millimeter-wave devices.
Study on Fabrication of Grinding Wheel in Selective Laser Melting
Authors: Li Shuai , Zhang Bi , Zhou Cong
Published: April 2021

Selective laser melting (SLM) is a promising technique to build grinding wheels with complex structures. In this paper, Ni-based self-fluxing alloys are chosen as bond materials to investigate single track formation on a steel substrate under different processing parameters. Results show that irregular and balling tracks are obtained with a low linear energy density (LED). The width of a melt pool increases linearly with LED. For LED values larger than around 0.9 J/mm, keyhole occurs in the melt pool, which is not desirable in the SLM process. Energy dispersive spectroscopy (EDS) mapping is performed to investigate the formation of the melt pool. Through an analysis on chemical distributions, it is found that the melt pool has a mixture of the partly melted substrate and powders. However, in the keyhole region, only the alloying elements of the substrate are detected due to the repulsion of the melted powder materials caused by the recoil pressure. This work can offer guidance on parameter optimization for the fabrication of SLMed grinding wheels.
Mechanical Study of Carbon Fiber Reinforced Plastic and Thin-walled Metal Liner in Bi-Material COPV Based on Grid Theory Optimization
Authors: Yu Bin , Zhang Jian Jun , Zhao Ji Peng , Ma Tian Ju
Published: April 2021

Composite over-wrapped pressure vessel (COPV) with ultra-thin metal liner and high strength carbon fiber reinforced plastic (CFRP) structure was widely used in space system. Meanwhile, there are some difficulties in the calculation of COPV stress-strain state related to the elastic-plastic liner and elastic composite. In this paper a novel design theory was proposed for calculating stress distribution in the bi-material COPV and determining the optimal thickness parameters of COPV based on traditional grid theory optimization. This new theory named Parameters Correspondence Relationship Structure Design Method (PCRSDM) can increase the design precision and structure performance factor of COPV compared to traditional grid theory. The correct models of mechanical characteristic between liner and CFRP are established from the view of optimized grid theory, the present theory is useful to develop a theoretical framework to calculate and design the COPV double shells. The COPV stress-strain behavior is also systemically studied by the ANSYS finite element analysis (FEA), the results show good agreement between FEA simulation and PCRSDM calculation. Both FEA and PCRSDM can meet the design requirements of COPV. A complete design, development and qualification testing of a specialized COPV used to satellite propulsion system was successfully conducted to verify the COPV design in terms of PCRSDM and FEA, the result show that PCRSDM is suitable for the design of COPV.

Influence of Load Interaction between Creep and TMF on the Life of Single Crystal Nickel-based Superalloy
Authors: Song Zi Yuan
Published: April 2021

Experimental investigation on the influence of load interaction on the life of Single Crystal Nickel-based Superalloy is conducted. Three kinds of load spectrums considering single and coupled failure mode are designed. Life tests are carried out under creep, thermo-mechanical fatigue (TMF), and creep-TMF interaction loading. The test results show that test lives, under the creep-TMF interaction loading, are lower than the life predictions given by the linear damage accumulation (LDA) rule, indicating that the load coupling can accelerate the damage evolution process. The microstructure of fractured specimens shows that under the creep-TMF interaction loading, rafting cause more dislocations to accumulate in the at γ/γ′ phase boundary, which could be the evidence of life decrease.

Published: April 2021

Background

The typical sign or main symptom in acute coronary syndrome (ACS) patients is chest pain, which is an initial benchmark or early sign for diagnosis. Certain factors, such as gender differences, the presence of diabetes mellitus or other clinical conditions, may make the patient not realize they have ACS. Therefore, this study aims to identify the characteristics of chest pain symptoms in male and female patients with ACS.

Design and methods

This is a non-experimental quantitative study, namely analytical observation using a cross-sectional approach within 4 months (January-April 2019). Furthermore, the samples were 53 ACS patients (28 male and 25 female).

Results

The chest pain characteristics that have a significant relationship with gender differences in ACS patients are shown based on the aspects of location, pain duration and quality. Male patients are more likely to feel pain at the left or middle chest, the duration is between <20 to >20 min with moderate pain quality, which tends to become severe, while females are more likely to feel pain at the chest which radiates to the neck and chin, the duration is usually >20 min, with mild to moderate pain quality.

Conclusions

The result showed a significant difference in chest pain characteristics in male and female patients with ACS. Regarding location, duration and quality of chest pain, male ACS patients mostly have more typical symptoms, while females’ symptoms are atypical.

Published: April 2021

This study aimed at providing pharmacological rationale for the ethnomedicinal use of Parquetina nigrescens root in the treatment of diarrhoea. The antidiarrhoeal activity of methanol root extract of P. nigrescens(MPN) was determined using castor oil-induced diarrhoea (COD), castor oil-induced enteropooling (COE) and gastrointestinal motility (GIT) tests. In COD, MPN at all doses significantly (p≤0.01) delayed the onset of diarrhoea and significantly (p≤0.05) decreased the number of wet faeces (with percentage inhibition of 52.2; 53.33 and 71.13 at 25, 50 and 100 mg/kg) respectively. The frequency of defecation was significantly (p≤0.01) decreased at 50 and 100 mg/kg. In COE, MPN at all doses significantly (p≤0.01) reduced the volume of intestinal content with percentage inhibition of intestinal fluid accumulation of 79.36; 47.62; 68.25 at doses of 25, 50 and 100 mg/kg respectively against control. In the GIT test, MPN significantly (p≤0.01) decreased the distance travelled by charcoal with a percentage reduction of peristalsis index of 41.19; 47.26; 43.46 at doses of 25, 50 and 100 mg/kg respectively against control. The percentage inhibition of GIT at all doses of MPN was 50.48, 39.00 and 45.62 respectively. MPN possesses antidiarrhoeal activity thus, the credence for its ethnomedicinal use in the treatment of diarrhoea.

Published: April 2021

The extensive supply of poor quality and/or counterfeit drug products in many developing countries has made it vital to frequently carry out suitable tests to assess bioequivalence (BE) in a cost-effective manner. This study was intended to assess the pharmaceutical equivalence and dissolution profile of amlodipine 5mg tablets marketed in Jos and Kaduna metropolis. Ten brands of Amlodipine 5mg tablets were obtained from different community pharmacies and evaluated for different quality control parameters such as percent drug content, friability, hardness, thickness, weight uniformity, disintegration time, and dissolution. The results showed that brands F and I failed the test for percent drug content while the rest of the brands passed it. In addition, all the brands passed the disintegrationand friability test while Brands C, F and I did not pass the hardness test. The dissolution profiles of all the brands were similar to the innovator brand at pH 6.8, whereas at pH 1.2, only four brands (B, E, H and I) had similar dissolution profile to the innovator. This study serves to justify for the assessment of in vitro parameters of commercially available amlodipine generics which may aid the prescribers’ decision making.

Published: April 2021

This study investigated toxicological effects of 5 and/or 10 mg/kg artemether (ART5 or ART10) and nevirapine (NVP) co-administration on serum biochemistry and some organs of Wistar rats. Drugs were administered intraperitoneally to 6 groups (n=6) for 21 days. On day 22, rats were sacrificed, sera obtained to determine electrolyte and antioxidant levels. Liver, kidney, lung and spleen were harvested and weighed for histological studies. Data analysed using oneway ANOVA, Dunnett’s post-hoc test and were considered significant at p≤0.05. There was no difference in superoxide, catalase, Na+ , K+ , Ca2+ and HCO3- levels in the treated groups. Cl- decreased (p≤0.05) in NVP + T80 and NVP + ART10 administered groups. MDA increased (p≤0.05) in NVP + ART10 group while GPx decreased. No pathological changes were observed in the liver of all treated groups but relative weight increased (p≤0.05) in NVPART10 treated group. The kidney of NVP-ART5 and NVP-ART10 treated groups did not differ in relative weight but showed some renal necrosis. The spleen and lung of ART10 treated group showed some pathological changes. The changes in relative liver weight, kidney tissue, Cl-, MDA and GPx levels of ART-NVP administered rats suggest the need for precautionary measures during drug treatment combination.

Introduction: MDR-TB poses a significant challenge to global management of TB. Laboratories in many countries among which include Nigeria are unable to evaluate drug resistance, and clinical predictors of MDR-TB might help target suspected patients.Method: The study was a cross sectional study design. Multistage sampling technique was employed in the selection of 403 tuberculosis patients. Data were analyzed using SPSS version 25. Level of significance was set at P<0.05.Results: Fifty three 53 (13.2%) of the total respondent had MDR-TB compare to national prevalence of 8% which is steeper among males 36(67.9%) (p>0.05). Education and Occupation shows a significant association with MDR-TB, (÷2=24.640, p = 0.007) and (÷2=14.416, p=0.006) respectively, smoking (r=0.074, p<0.05) and alcohol consumption (r=0.083, p>0.05) show no significant association with occurrence MDR-TB.Conclusion: Previous TB treatment and Adherence with treatment regimen were found to be the major risk factor for MDR-TB. Targeted educational intervention for patients and their contacts may minimize the non-adherence with prescribed TB treatment and lessen MDR-TB magnitude.
