A glandular-like kallikrein enzyme, a member of a well-characterized family of specific arginyl endopeptidases that may be involved in prohormone processing, has previously been shown to be present in the anterior and neurointermediate lobes of the rat pituitary. We isolated glandular-like kallikrein cDNAs from cDNA libraries prepared from these two tissues. By nucleotide sequence, restriction ...

The monoclonal antibody Myc 1-6E10 was used in an immunocytochemical technique to examine the expression of the c-myc oncogene in normal endocervices and those with glandular intraepithelial neoplasia and invasive malignancy. Eleven of 14 normal endocervical biopsy specimens did not express the gene, while three showed nuclear, or light basal cytoplasmic localisation of the gene product, or bot...

The impact of digitalization on the average glandular doses in 49 mammographic units participating in the Flemish Breast Cancer Screening Program was studied. Screen-film was changed to direct digital radiography and computed radiography in 24 and 25 departments respectively. Average glandular doses were calculated before and after digitalization for different PMMAphantom thicknesses and for gr...

BACKGROUND Benign ectopia of prostatic glandular tissue in the seminal vesicles is rare with only three prior cases reported in the literature. Prostate cancer, arising within prostatic ectopia in the seminal vesicles, has never been described and therefore presents a challenge in both diagnosis and management. CASE PRESENTATION Herein, we report a rare case of prostatic adenocarcinoma in ect...

The genus Amphictene is reported for the first time from Mexico. Previous records for America are restricted to Brazil (Amphictene catharinensis) (Grube, 1870), and Guatemala (Amphictene guatemalensis) (Nilsson, 1928). In this paper we describe a new species, Amphictene helenae sp. n., characterized by the presence of three pairs of tentacular cirri, while other species have only two pairs. The...
