An improved method for handling tissues for immunofluorescence.

Improved method for trypsin digestion of Paraplast sections before immunofluorescence staining.

Formalin-fixed, Paraplast-embedded tissue sections mounted on subbed slides were digested with crude trypsin in modified Sorensen phosphate buffer containing sodium fluoride before immunofluorescence staining. This method prevented detachment of sections from slides during processing, thereby permitting immunofluorescence and histological examinations of adjacent serial sections.

a paradigm shift away from method-wise teaching to strategy-wise teaching: an investigation of reconstructive strategy versus communicative strategy

چکیده: هدف اصلی این مطالعه ی توصیفی تحقیقی در حقیقت تلاشی پساروش-گرا به منظور رسیدن به نتیجه ای منطقی در انتخاب مناسبترین راهکار آموزشی بر گرفته از چارچوب راهبردی مطرح شده توسط والدمر مارتن بوده که به بهترین شکل سازگار و مناسب با سامانه ی آموزشی ایران باشد. از این رو، دو راهکار آموزشی، راهکار ارتباطی و راهکار بازساختی، برای تحقیق و بررسی انتخاب شدند. صریحاً اینکه، در راستای هدف اصلی این پژوهش، ر...

An improved method for staining kinetochores of human chromosomes.

An improved method, which exhibited simultaneously clearly kinetochores and the nucleolar organizer regions of human chromosomes by pretreating of human metaphase chromosomes with HCl and NaOH, followed by staining with silver nitrate and visualizing using ammoniacal silver, is described in the present communication. It has important role for analysis of kinetochore variation, mechanism of chro...
