BACKGROUND Inevitable loss of diagnostic material should be minimized during cell block preparation. We introduce a modified agarose cell block technique that enables the synthesis of compact cell blocks by using the entirety of a cell pellet without the loss of diagnostic material during cell block preparations. The feasibility of this technique is illustrated by high-throughput immunocytochem...
background &objective: breast cancer is the most common female malignancy. detection of dna of human papillomaviruses (hpvs) in breast carcinomas suggests that the virus may play a role in the pathogenesis of this disease. the aim of this study was to evaluate the frequency of hpvs genotypes 6, 11, 16, 18 and 31 in paraffin-embedded tissue samples of invasive breast carcinomas. methods: thr...
Aim: In this study, we investigated the immune activity of Sox-9 and Cited-1 in women with placenta accreta. Material Methods: 20 healthy accreta were processed for routine histological tissue processing. Placentals samples dissected fixed 10% formaldehyde solution. Samples embedded paraffin blocks. Clinical biochemical parameters recorded. Placental sections cut from blocks stained immunostain...
OBJECTIVE To describe and discuss the design, building and usefulness of tissue microarray (TMA) blocks for the study of salivary gland tumors (SGTs). STUDY DESIGN Two hundred thirty-eight formalin-fixed, paraffin-embedded SGTs were arranged in blocks of TMA using a manual tissue arrayer. Three representative cores of 1.0, 2.0 or 3.0mm were taken from each original block and their characteris...
Biopsies or tissue samples from cancer patients are routinely stored in formalin-fixed, paraffin-embedded (FFPE) tissue blocks. Sequencing these samples has proved challenging, because the process partially degrades and limits the amount of genomic material. Advanced approaches, such as nextgeneration sequencing (NGS), generate high-quality genomic data and are suitable for analyzing these valu...
Breast cancer is the most prevalent malignancy in women throughout the world. Similar to other cancers, a strong relationship between breast cancer and environmental factors such as infectious agents has been reported. Toxoplasma gondii is a protozoan parasite which may play a role in cancer induction. The present study aimed to investigate a possible association between a history of T. gondii ...
PURPOSE The Cooperative Prostate Cancer Tissue Resource (CPCTR) is a National Cancer Institute-supported tissue bank that provides large numbers of clinically annotated prostate cancer specimens to investigators. This communication describes the CPCTR to investigators interested in obtaining prostate cancer tissue samples. EXPERIMENTAL DESIGN The CPCTR, through its four participating institut...
