In 1994 a squared two -dimensional barcode was invented by Toyota Company which changed and speed up the concept of tracking and identification. They chose its name QR which stands for Quick Response code. Quick Response codes can convey data such as show a geographical location, make a phone call, link to a simple text, link to a website or temp late email, access to a portable document format (PDF), display an image, link and download a specific application on a mobile device or Wi- Fi login. Academic journal leaders should notice that QR code as a unique shaped matrix code is increasingly being u sed by prestigious publishers and scientific journals. But has been ignored by eastern scientific journals and academic institutes for many years. As the author checked all English Iranian journals, no Iranian academic publication or publisher has and uses QR code or even barcode on their websites or on their journal covers till 16 Dec 2019. In this review, the author aimed to explore the use of QR codes specifically for academic publications, identify perceptions towards their use and any information that has been encountered during implementation .

Objective: Stem cells that have unlimited proliferation potential as well as differentiation potency are considered to be a promising future treatment method for incurable diseases. The aim of the present study is to evaluate the future trend of stem cell researches from researchers’ viewpoints. Materials and Methods: This was a cross-sectional descriptive study on researchers involved in stem cell research at Royan Institute. We designed a questionnaire using a qualitative study based on expert opinion and a literature review. Content validity was performed using three rounds of the Delphi method with experts. Face validity was undertaken by a Persian literature expert and a graphics designer. The questionnaire was distributed among 150 researchers involved in stem cell studies in Royan Institute biology laboratories. Results: We collected 138 completed questionnaires. The mean age of participants was 31.13 ± 5.8 years; most (60.9%) were females. Participants (76.1%) considered the budget to be the most important issue in stem cell research, 79.7% needed financial support from the government, and 77.5% felt that charities could contribute substantially to stem cell research. A total of 90.6% of participants stated that stem cells should lead to commercial usage which could support future researches (86.2%). The aim of stem cell research was stipulated as increasing health status of the society according to 92.8% of the participants. At present, among cell types, importance was attached to cord blood and adult stem cells. Researchers emphasized the importance of mesenchymal stem cells (MSCs) rather than hematopoietic stem cells (HSCs, 57.73%). The prime priorities were given to cancer so that stem cell research could be directed to sphere stem cell research whereas the least preference was given to skin research. Conclusion: Regenerative medicine is considered the future of stem cell research with emphasis on application of these cells, especially in cancer treatment.

Publishing in an ISI or high impact factor journal is a concern for researchers to increase their citation record and their prestige in the world of Science. The study shows that search engine optimization (SEO) not only increases visibility of scientific articles but also helps to receive more views, downloads, and citations. This paper is the first study looking SEO in a new approach.

Purpose Isolating spermatogonia cells with high purity and viability and achieving better survival rate following cryopreservation Methods Isolating the cells by Magnetic Activating Cell Sorting (MACS) method using anti CD49f (α6 integrin) antibody and Dynabeads and freezing in DMSO-based freezing mediums containing three different FBS concentrations of 50%, 60% and 70%. Results The mean (±SD) purity of the isolated cells was 92.52±3.57 (range 92.43–98.25). The cells were frozen in group I, II and III had mean 39.60±1.48 (range 37.98–41.62), 89.05±3.83 (range 80.83–90.33) and 90.52±1.71 (range 89.07–92.52) viability, respectively. Conclusion Higher viable cell counts and purity can be attained by the use of α6 integrin and magnetic beads. After the thawing of spermatogonial cells, optimum viability was achieved in freezing media containing 60% FBS.

One of the most important challenges in medical libraries is to link their clients to resources such as full-text journal articles. There are many databases that can provide access to all electronic resources such as Institute of Electrical and Electronics Engineers Xplore for engineers. To achieve, researchers and librarians must log in to their university websites or have a username and a password for each publisher or database. Kopernio is a browser extension as a plugin and is designed to fix this issue. In this review, we aim to describe what Kopernio is and how it can be adjusted and explore some of its advantages. A brief discussion of similar products is also included.
