Rationale, aims, and objectives: Cell‐based therapeutics are among the latest advances in health care technologies. The rapid evolution of stem cell science in Iran has necessitated the application of scientific achievements in clinical settings. However, various issues hindered their translation, in particular, impediments in the interactions of basic stem cell scientists and clinicians. We highlighted the impediments in the interactions of stem cell scientists and physicians involved in the opinion of professionals from both groups. Method: This qualitative research was conducted with thematic analysis, performed by purposive sampling. Thirty‐two distinguished stem cell scientists and clinicians were interviewed to identify their perspectives on this matter. MAXQDA 2018 was used to classify the axial codes based on factors related to communications inefficiencies. The analysis of coded data recognized 18 subthemes and six major themes. Results: Central themes include different registers of the two parties, counterproductive clusters hampered networking, external communication barriers, the competition to access resources, leadership conflicts, and the dissatisfaction of stakeholders with their share. Conclusions: Most of the impediments were seemingly global, for example, the incoherent medical and basic science educational systems, the vulnerable career path of physician‐scientists, and an increasing tendency towards overspecialization. However, some local specific issues were also described, for example, limited funding opportunities and the negative impacts of the division of medical education from the ministry of science, research, and technology in Iran. Proposed interventions include the reinforcement of physician‐scientist programs, designing a distributed leadership model, and bringing back the scientific integrity to higher education in Iran.

Objective: The aim of the present study was to investigate whether there is an association between serum concentrations of calcium, phosphate, alkaline phosphatase, parathyroid hormone (PTH), and vitamin D and temporomandibular disorders (TMDs).Methods: In this case-control study, 51 patients with TMDs (28 patients with TMJ clicking, 5 patients with muscular disorders, and 18 osteoarthritis patients) and 29 healthy subjects within the age range of 20-50 years as the control group, were referred to the laboratory for calcium, phosphate, alkaline phosphatase, PTH, and vitamin D (25 OHD) analysis tests. The TMJ status of all participants was examined according to RDC-TMD criteria by a prosthodontist who is an expert in TMDs. The results were analyzed with Fisher's precise test.Results: No statistically significant difference was observed between TMD patients and healthy subjects.Conclusion: Serum concentrations of calcium, phosphate, alkaline phosphatase, PTH, and vitamin D are not associated with TMDs.

Background: Visceral leishmaniasis (VL), so-called Kala-azar is a life threating parasitic infectious disease caused by Leishmania spp. L. infantum is the main causative agent for Mediterranean form of Kala-azar which is endemic in northeastern Iran. This study attempted to investigate existence of canine visceral leishmaniasis (CVL) in Khorasan Razavi., Methods: Between 2014 and 2016, tissue samples collected from spleen and liver of 192 stray dogs were examined to investigate existence of L. infantum . Kinetoplast DNA (k-DNA) PCR was performed to identify the species of parasites. The positive PCR products were sequenced in both directions to confirm the kDNA PCR results., Results: Among samples obtained from 192 dogs, kinetoplast DNA of L. infantum was detected in two female dogs. L. infantum was confirmed by sequence analysis of PCR products., Conclusion: Our data confirm stray dogs play as potential reservoirs for VL in this province. Further investigation will be necessary to clear role of stray dogs in the transmission of L. infantum to human and domestic dogs., Competing Interests: Conflict of interest The authors declare that there is no conflict of interests.

Mucosal leishmaniasis is a major problem in Latin America but has been rarely noticed in our region. Although there have been a few reports of mucosal involvement especially in the oral cavity from Southwest Iran, yet none have been presented from the Northeast where Leishmania tropica is the major concern. We report a patient with endonasal leishmaniasis due to L. tropica, an extremely rare entity in immunocompetent patients in our region. He presented with a mass in the left nasal vestibule causing a sense of obstruction on the same side, accompanied by occasional rhinorrhea and mild epistaxis. This case exemplifies the need for considering leishmaniasis as a differential diagnosis for nasal obstruction in this endemic area.
