Expression of Neuronal Markers, NFP and GFAP, in Malignant Astrocytoma
Hashemi, Forough,Naderian, Majid,Kadivar, Maryam,Nilipour, Yalda,Gheytanchi, Elmira Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15
Background: Immunohistochemical markers are considered as important factors in diagnosis of malignant astrocytomas. The aim of the current study was to investigate the frequency of the immunohistochemical markers neurofilament protein (NFP) and glial fibrillary acidic protein (GFAP) in malignant astrocytoma tumors in Firoozgar and Rasool-Akram hospitals from 2005 to 2010. Materials and Methods: In this cross-sectional study, immunohistochemical analysis of NFP and GFAP was performed on 79 tissue samples of patients with the diagnosis of anaplastic and glioblastoma multiform (GBM) astrocytomas. Results: The obtained results demonstrated that all patients were positive for GFAP and only 3.8% were positive for NFP. There was no significant association between these markers and clinical, demographic, and prognostic features of patients (p>0.05). Conclusions: NFP was expressed only in GBMs and not in anaplastic astrocytomas. It would be crucial to confirm the present findings in a larger number of tumors, especially in high grade gliomas.

The learning approaches can help anatomy teachers design a suitable curriculum in harmony with their students’ learning styles. The research objective is to evaluate gross anatomy learning styles and strategies preferences of Iranian medical students at Kashan University of Medical Sciences (KAUMS). This cross-sectional questionnaire-based study was carried out on 237 Iranian medical students. The students answered questions on approaches to learning anatomy and expressed opinions about learning anatomy in medical curriculum. The data were analyzed to disclose statistically significant differences between male and female students. Iranian male and female students were interested in learning anatomy using notes, plastic models, pictures and diagrams, clinical context, dissection and prosection of cadavers; however, they rarely used cross-sectional images and web-based resources. Both groups of medical students used region and system in learning anatomy. However, there existed some striking differences, particularly in having difficulty in studying anatomy using cadaveric specimens, using books alone, and learning it in small groups. Male students were less interested in learning with cadavers than female counterparts. However, female students were more interested in learning anatomy in small groups. This study suggests that instructors should design gross anatomy curriculum based on limitations of using dissection of cadaver in Iranian universities, emphasis on the applied anatomy, and learning of gross anatomy in small groups.
