These products can be used in the microencapsulation of bioactive compounds, stabilization of enzymes and smart packaging. In the electrospinning method, a high voltage is used to create a nanofibers-particles. When the electric field overcomes the surface tension of the droplet, a jet exits the polymeric solution and is formed along the collector surface as it stretches toward the collector panel of the nanofiber. Parameters including molecular weight and polymer microstructure characteristics such as electrical conductivity, viscosity, surface tension, and the electrical potential applied by the device, solution flow rate, distance between the tip of the needle and the collector plate and sometimes the material of the collector plate are effective in the formation of electrospun fibers and particles. In this review, we discussed and evaluated the production stages, the strengths and weaknesses of the fibers produced from proteins and polysaccharides, and their functional properties and potentials, especially in food and drug sciences.","PeriodicalId":14723,"journal":{"name":"Jorjani Biomedicine Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74942615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, evaluation of the effective therapeutic models alleviating the patients’ negative emotions is of paramount importance. This study aimed to examine the effect of mindfulness-based stress reduction (MBSR) on anger and stress in patients with coronary heart disease after coronary artery bypass graft (CABG). Methods: This research had an A-B single-subject design. The research population encompassed all patients with coronary heart disease referring to Shahid Madani Hospital of Tabriz, Iran during the second half of 2016 for rehabilitation measures. Four patients were selected using convenience sampling. Before the interventions, the participants completed state-trait anger expression inventory (STAXI-2, Spielberger) and depression anxiety stress scale (DASS) throughout two consecutive weeks, which led to establishing two baselines. Afterwards, they received mindfulness-based stress reduction training during seven consecutive weeks and completed the questionnaires after each intervention. Percentage of recovery, percentage of non-overlapping data (PND), standard mean difference (SMD), and effect size were used to analyze the data, and eye diagram analysis was adopted to interpret the data. Results: The findings indicated that the mean recovery rate for all participants was 0.84 and its effect size index was 2.7. Moreover, the mean percentage of recovery and the effect size index of mindfulness intervention on the patients’ anger were 0.18 and 1.38, respectively.

N. Azari, N. Jabari","doi":"10.29252/JORJANIBIOMEDJ.6.2.77","DOIUrl":"https://doi.org/10.29252/JORJANIBIOMEDJ.6.2.77","url":null,"abstract":"Kiomars Niaz Azari, Department of Management, Sari Branch, Islamic Azad University, Sari, Iran k.niazazari@ gmail.com Abstract Background and objectives: Knowledge-based economy is one of the major parts of the resistance economy and is recognized as the essentials of the information technology age. The managers and faculty members play an important role in this regard. This study aimed to explain the dimensions of the resistance economy based on the knowledgebased economy in universities of medical sciences. Methods: This qualitative research had a purposeful sampling method. Data were collected via library and field research. In the library method, the relevant specialized scientific texts and resources were exploited, whereas in the fieldwork, the researcher interviewed 24 faculty members. After that, the interviews were analyzed. In the field method, the texts and books were evaluated and information searched in scientific and specialized websites. In the field research and after coordination with faculty members and main elites with a history of article or innovation production or a management background, the opinions of the interviewees were asked about some questions in a semistructured manner. In addition, three-stage coding, open coding, axial coding, and selective coding were applied in the research. To perform open coding, the main sentences were recorded as codes, followed by classifying the similar codes. In axial coding, the classes were related to their subclasses by comparing the primary classes of open coding and revolving the ones that resembled around the common axis. In selective coding, the integration and refining process of the categories was performed to form and present the model, and the dimensions were extracted and explained. Results: From the perspective of the faculty members and key experts, resistance economy based on knowledge-based economy in universities of medical sciences could be explained in dimensions of information and communications technology, innovation and entrepreneurship in medical sciences, human resources and knowledge-based team, administrative and structural system, resources of equipment and abilities, policy and socio-environmental impacts. Each of these dimensions also included sub-groups and special themes. Conclusion: Moving towards the knowledge-based economy is one of the requirements of the country on the path to economic development, which involves dimensions such as information and communications technology, innovation and entrepreneurship, strategic planning and policy-making, formulating and ensuring the legal framework and legal system, supplying and developing electronic infrastructures, and paying attention to capabilities and resources of facilities.","PeriodicalId":14723,"journal":{"name":"Jorjani Biomedicine Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86362213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Birth spacing is defined as the interval between two live births and determines the fertility rate. In addition, it provides the opportunity for assessing attitudes related to the size of the household, fertility differences and child mortality rate. Today, the mean birth spacing of a woman in any country is an indicator for assessing the socioeconomic development and life quality in that region (1). Many studies in developing countries have shown that women with large and small families have a smaller and larger birth spacing, respectively. Therefore, there is a reverse relationship between birth spacing and total or cumulative fertility of a woman.
