BACKGROUND Surgical removal of jugular foramen (JF) neurinomas remains controversial because of their radicality in relation to periosteal sheath structures. OBJECTIVE To clarify the particular meningeal structures of the JF with the aim of helping to eliminate surgical complications of the lower cranial nerves (LCNs). METHODS We sectioned 6 JFs and examined histological sections using Mass...
مقدمه:با توجـه به قابلیت ایجاد تغییـرات نئوپلاستیک و قدرت تکثیر بیشتر و عود بالاتر بعد از برداشت کیست دنتی ژروس نسبت به فولیکول دندانی هدف از این مطالعه، بررسی ایمونوهیستوشیمیایی بیان mib-1در فولیـکول دنـدانی و کیـست دنتـی ژروس بود. مواد و روش ها: در این مطالعه توصیفی-تحلیلی برش های تهیه شده از بلوک های پارافینه 12 مورد کیست دنتی ژروس و 12 مورد فولیکولدندانی با استفاده از روش ایمونوهیستوشیمی ...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
abstract the aim of the present study is to explore the impact of the cognitive reading strategy instruction on learners reading self-efficacy and their reading achievement. in order to fulfill this purpose, from 120 participants, 90 intermediate efl learners as an experimental group were chosen from three different educational settings namely, yazd university, yazd science and art un...
abstract this study aimed at investigating the effect of bilingual teaching of cognate words (persian-english) on iranian upper intermediate efl learners’ knowledge of lexical development. for this purpose,100 subjects participated in this study out of which 40 learners were selected for this study and they were assigned into two groups, control and experimental. cross-language cognates (wor...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
Extended stabilization of gaze leads to disappearance of dim visual targets presented peripherally. This phenomenon, known as Troxler fading, is thought to result from neuronal adaptation. Intense targets also disappear intermittently when surrounded by a moving pattern (the "mask"), a phenomenon known as motion-induced blindness (MIB). The similar phenomenology and dynamics of these disappeara...
BACKGROUND Argyrophilic nucleolar organizer regions (AgNORs) and MIB-1 as proliferating activities have been applied separately to assess the malignant potential of cancer cells. We conducted staining of AgNORs and MIB-1 in 42 surgically-resected invasive breast carcinomas. MATERIALS AND METHODS Paraffin-embedded sections were used for double staining and the mean AgNOR counts in 100 MIB-1-po...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
