The Relationship between Faculty Members’ Perception of Organizational Culture Types and their Preferences for Instruction and Counselling in Iranian College of Education and Psychology

AbstractThe purpose of this research was to study the relationship between faculty members’ perception of organizational culture types and their preferences for instruction and counselling responsibilities in Shiraz, Tehran and Ahvaz both public and private Universities, Colleges of education and psychology. Statistical population of this study comprised of all Shiraz, Tehran and Ahvaz colleges of Education and Psychology faculty members. Using classified random sampling, 4 colleges were selected. In order to collect data two instruments were used in this study i.e. Counsellor Educator Task importance Instrument (CETII) (Orr, 2005) and Organizational Culture Assessment Instrument (OCAI) (Cameron & Quinn, 1999). Results indicated a significant effect of organizational culture types for scholarship and service responsibilities. Additionally, there was a significant organizational culture type×university type interaction effect for scholarship and teaching responsibilities. And a significant organizational culture types×Academic Rank interaction effect for teaching and service responsibilities as well. However, the results showed neither significant organizational culture type×university type interaction effect nor significant organizational culture type×years of service interaction effect for teachers’ counselling and instruction responsibilities

Zwitterionic (4-benzyl­piperidinium-1-yl­meth­yl)phospho­nate

The title compound, C13H20NO3P, exists as a zwitterion: the phospho­nic acid group has transferred its H atom to the amino group. The piperidine ring adopts a chair conformation. Mol­ecules are linked via hydrogen bonding to form a linear chain

{2-[(4-Bromo­phen­yl)imino­meth­yl]pyridine-κ2 N,N′}diiodidozinc(II)

In the title compound, [ZnI2(C12H9BrN2)], the metal centre displays a moderately distorted tetra­hedral coordination geometry defined by two iodide anions and two N atoms of the organic ligand. The dihedral angle between the pyridine and benzene rings is 15.15 (13)°

Bis{2-[(4-bromo­phen­yl)imino­meth­yl]pyridine-κ2 N,N′}copper(I) tetra­phenyl­borate

In the crystal structure of the title compound, [Cu(C12H9BrN2)2](C24H20B), the copper(I) cation is coordinated by four N atoms of two crystallographically independent 2-[(4-bromo­phen­yl)imino­meth­yl]pyridine ligands within a distorted tetra­hedron

Comparing the viability and in vitro maturation of cumulus germinal vesicle break down (GVBD) oocyte complexes using two vitrification techniques in mice

Background: Vitrification is assumed to be a promising method to cryopreserve human oocytes but still needs optimizing. Objective: The aim of this study was to improve the single step and step-wise vitrification effects on maturing mouse GVBD oocytes by ethylene glycol (EG) in conventional straws. Materials and Methods: Oocytes with compact cumulus cells were cultured for 3hr in TCM199 supplemented with 10% fetal bovine serum (FBS) in 5% CO2 in air. GVBD oocytes were randomly allocated into three groups. (1) Control (non-vitrified group), (2) exposed to single-step vitrification (contained of EG 20%+0.5M sucrose), (3) exposed to step-wise vitrification (2%, 5%, 10%, 20%EG +0.5M sucrose). In vitrification groups,oocytes were thawed and underwent additional 21 hr maturation. Viability of oocytes and maturation to MII stage were analyzed using inverted microscope and additionally by staining of propidium iodide and Hoechst 33342. Results: All non-vitrified oocytes were viable after 24 hr; however, viability of vitrified samples in single-step group was significantly lower than that of the step-wise and control Groups. Also, the maturation rate in the step-wise group was significantly higher (p < 0.05) compared to single-step. Conclusion: These results suggest that step-wise vitrification of GVBD oocytes as compared to single step vitrification was better in the rate of survival and in vitro maturation of oocytes

The comparison of self-renewal gene expression pattern in cancer cell lines, tumor tissue and normal tissue of the bladder tumor

زمینه و هدف: یکی از دلایل ایجاد سرطان، بیان نا به جای ژن های کنترل کننده مسیر خود بازآفرینی در سلول سرطانی است، لذا در این مطالعه بیان ژن های اصلی کنترل کننده مسیر خود بازآفرینی شامل OCT4، NANOG، KLF4، SOX2 و Nucleostemin در دو رده سلولی 5637 و HT1376، بافت سرطانی و بافت سالم نمونه های بیوپسی بافت سرطانی مثانه، مورد بررسی قرار گرفت. روش بررسی: در این مطالعه آزمایشگاهی، رده های سلولی در فلاسک های کشت و محیط کشت کامل RPMI1640 کشت و نگه داری شدند و نمونه های بیوپسی بافت سرطان از میان نمونه های سرطانی ارسالی به آزمایشگاه پاتولوژی و به صورت بافت تازه، با توجه به علائم بالینی و یافته های آزمایشگاهی، انتخاب و مورد بررسی قرار گرفتند. حاشیه های نمونه های بیوپسی به عنوان بافت سالم انتخاب گردید. بیان ژن های مورد نظر در سطح بیان mRNA در دستگاه Real-Time PCR تعیین و با فرمول ct∆∆ مورد آنالیز قرار گرفته بصورت میزان تغییر بیان ژن (Fold change) ارائه گردید. یافته ها: ارزیابی نتایج Real-Time PCR نشان داد ژن های مورد مطالعه در رده های سلول سرطانی و نیز بافت سرطانی توده های بیوپسی سرطانی مورد مطالعه بیان می شوند در حالیکه در بافت سالم توده های بیوپسی مورد اشاره، بیان این ژنها مشاهده نمی شود. نتیجه گیری: بیان ژن های OCT4، NANOG، KLF4، SOX2 و Nucleostemin لازمه القاء توان خود بازآفرینی است. نتایج این تحقیق نشان می دهد این ژن ها در بافت سرطانی و رده های سلول سرطانی در مقایسه با بافت سالم بیان بالاتری از خود نشان می دهند. لذا به نظر میرسد مطالعه علت فعال شدن مجدد این ژنها میتواند در شناسایی ماهیت سرطان کمک کننده باشد

Dichlorido{2-[(4-iodo­phen­yl)imino­meth­yl]pyridine-κ2 N,N′}copper(II)

The CuII atom in the title complex, [CuCl2(C12H9IN2)], has a square-planar coordination being N,N′-chelated by the Schiff base ligand, and by two Cl atoms. The geometry is distorted towards square pyramidal owing to a long Cu⋯Cl inter­action of 2.941 (1) Å. This results in the formation of a zigzag chain structure propagating in the c-axis direction
