Influence of different cytokinins used in in vitro culture on the stoma morphology of pistachio (Pistacia vera L. cv. Siirt)

Three different cytokinins (BA, kinetin and TDZ at 1 mg/l) were tested in order to study their effects on pistachio stoma morphology. Additional BA concentrations of 0.25, 0.625 and 2 mg/l were also tested.The stoma morphology of pistachio leaves in vitro was affected by cytokinins. Stomas obtained from 1 mg/l BA medium were similar to those developed in vivo. TDZ, kinetin and other BA concentrations resulted in abnormal stoma development

Consumers Increasing Confidence towards Social Commerce: The Role of Social Media Marketing, Trust and Social Media Engagement

Recent research shows peoples are spending more time on digital online platforms like Facebook, and others. Of which business organization sees as an opportunity for expanding businesses.

The impact of Covid-19 on E-business practices and consumer buying behavior in a developing country

Online trade has shown a sharp increase since the outbreak of pandemic Coronavirus. The COVID-19 has affected almost all financial and business activities around the world, even in Pakistan. It has changed the way consumers used to shop before the pandemic outbreak. Many companies until recently have developed and created their online stores and making up the most of their sales using internet channel. Consumer have no other choice but shop from home. In this research study, we discuss the impact of COVID-19 on e-business practices and consumer behavior in Pakistan. The theory of acceptance model has been applied where consumer behavior, e-business, and COVID-19, and posted as a key construct of the proposed research model. Structural Equation Modelling approach has been used to examine the interrelationship of variables of research. We applied two-step recommended Structural Equation Modelling approach, first, validate the constructs by using Confirmatory Factor Analysis, and then conducted Structural Equation Modelling path analysis and report the results, which indicated that in the present scenario COVID-19 has significantly impacted both e-businesses and consumer buying behavior in the context of Pakistan. This research briefly highlights the e-commerce trends and discusses the rapidly growing scope for online businesses and makes several future research suggestions, especially in the context of cultural and other barriers such as digital payment adoption in developing economies. This study limitation is the study sample and context-specific to Pakistan

Course Contents of English Language Textbooks and their Relevance to Learners’ Culture in an Islamic Context

The study is an attempt at analyzing the cultural authenticity of the course contents of English as a foreign language at International Islamic University Islamabad. This study assumes that these course contents increase cultural barriers for the learners who belong to a different set of cultural values and religious and educational background. It traces the limitation of foreign textbooks writers because of their unawareness of the local culture and the social, educational and religious environment. The study on the one hand questions the suitability of such textbooks for the learners (mostly from religious institutions) and on the other hand gives proposals for the development of English textbooks based on indigenous or Islamic culture. Usually, the evaluation of course contents is descriptive in nature and is done to describe or find out a problem rather than to address it. To bring an improvement in course contents is the basic goal of course evaluation. Although, it would be irrelevant to manipulate a problem statement for this type of research yet ignoring the student factor in writing English text books and selecting these books without doing a prior research into the needs analysis of the learners can be cited as the main problem which inspired the study. This study adopts both a descriptive as well as a prescriptive approach. It analyses the contents to see what is there in the contents and what is required for the learners from a cultural perspective. On the basis of its two fold description the study has given suggestions as to what should be an ideal situation for the selection, adaptation and development of English language textbooks for the learners. The main hypothesis of the study was that there was no cultural relevance between the objectives of the learners for learning English, their social and educational background and the contents of the course book. The inappropriateness of the theories that advocate the inclusion of target language culture in language courses as an essential factor for teaching and learning English in every situation and for all learners is the secondary hypothesis of the study. The study has narrowed down its focus to the cultural relevance of the course contents being taught at the IIUI, the communication gap between the authors and the target learners, and to give suggestions regarding the possibility to include the learners’ culture in English language courses.   The study adopts a first glance evaluation in the light of guidelines provided by pedagogical theorists and deliberately avoids learners’ response method (in which learners responses are measured) because of the   researcher’s own interest in the impressionistic evaluation. The main purpose of the study was to bring the learners in the lime light of focus to make teaching of English more learners’ centered, to create awareness among the teachers, policy makers and course designers to consider learners needs in the process of textbooks selection and development. The study proves that the themes, setting, characters and worldview, presented in the contents of the book represent a foreign and unfamiliar world for the learners. The study suggests that the learners would be more motivated to learn English if language were presented in the context with which the learners could identify themselves.

MEFV mutations in systemic JIA

Background: Systemic form of juvenile idiopathic arthritis (JIA) is regarded as an autoinflammatory disease. Certain genetic polymorphisms in genes coding inflammatory proteins have been associated with the disease. On the other hand mutations of the MEFV gene cause a monogenic autoinflammatory disease, Familial Mediterranean Fever (FMF). In a previous study in adult rheumatoid arthritis 3 out of the 25 British patients who developed secondary amyloidosis had a mutation/polymorphism in the MEFV gene. Aim: To analyse whether mutaions in the MEFV gene had an association with systemic JIA. Patients and methods: MEFV mutations were screened in a total of 32 systemic JIA patients. All had been classified as systemic JIA according to the Durban JIA criteria. None had disease characteristics that met the Tel Hashomer criteria for the diagnosis of FMF. Results: 2 carrier for M694V and two patients who were homozygote for MEFV mutations. Both of these patients were among the most severe patients in the group. One had an excellent response to etanercept whereas the other was resistant to anti-TNF and other conventional treatments and had only a partial response to thalidomide. Although the number of severe mutations were increased in this small group of patients with systemic JIA the difference with the Turkish population did not reach statistical significance, but the disease causing mutation (M694V) was significantly high in the patients with systemic JIA(p = 0.02). Conclusion: However, the severe disease course in the aforementioned patients suggest that MEFV mutations may be a modifying genetic factor in systemic JIA.PubMe
