This paper presents an alternative approach to the study of gross anatomy which may be pursued in Medical Schools using plastination techniques. Specimens fixed with formalin and alcohol-based techniques were utilized as the source of specimens to be plastinated; the reason for this choice was a result of the decreased organ availability in Italy due to religion and restrictive laws. The proced...

Integrated ultrasonic backscatter has been related to collagen deposition in fibrotic myocardium. The purpose of our study was to measure the integrated ultrasonic backscatter in the right and left ventricles of 10 normal freshly excised canine hearts and five normal formalin-fixed human hearts. A 2.25 MHz, 50% fractional bandwidth transducer was positioned at the transducer focal distance from...

BACKGROUND Identifying the influence formalin fixation has on RNA integrity and recovery from clinical tissue specimens is integral to determining the utility of using archival tissue blocks in future molecular studies. For clinical material, the current gold standard is unfixed tissue that has been snap frozen. Fixed and frozen tissue however, both require laser capture microdissection to sele...

We used formalin-fixed human spinal cord and dorsal root ganglia as immunogens to generate monoclonal antibodies (mAb) which immunohistochemically react with neurons in formalin-fixed human tissue sections. Three of the mAb recognized all neuronal populations studied, including those in spinal cord, dorsal root ganglia, cerebellum, and cerebrum. A fourth mAb recognized neurons within spinal cor...

Formalin-stored HEp-2 cells were used to assay Escherichia coli for adherence. Cells refrigerated in formalin for up to 28 days and used in a wet assay format demonstrated an assay sensitivity ranging from 94 to 98% to detect enteroaggregative E. coli (EAEC). HEp-2 cells first fixed and stored with formalin and then stored dry in ambient conditions for 6 weeks demonstrated an assay sensitivity ...

– The present paper reports the extraction of DNA from formalin-fixed Pontoporia blainvillei tissues. Following the Vachot and Monerot (1996) protocol, fragmented DNA (300-700bp) was extracted from more than 95% of liver and muscle samples. DNA yield in liver samples was significantly higher than in muscle samples (4.574 ± 1.169μg DNA/mg versus 0.808 ± 0.297μg DNA/mg). Similar results were obta...
