Intracellular Ca2+ is released from intracellular stores in the endoplasmic reticulum (ER) in response to the second messenger inositol (1,4,5) trisphosphate (InsP3) [1,2]. Then, a poorly understood cellular mechanism, termed capacitative Ca2+ entry, is activated [3,4]; this permits Ca2+ to enter cells through Ca(2+)-selective Ca(2+)-release-activated ion(More)
Serous borderline ovarian tumors have a favorable prognosis, and recurrences are uncommon. The factors influencing recurrence are not fully understood. Epithelial inclusions are identified in serous borderline ovarian tumors and are traditionally referred to as epithelial implants, which often show epithelial proliferation. We investigated whether the(More)
The diagnosis of atypical glandular cells of undetermined significance (AGUS) in liquid-based cervical cytology specimens shows significant underlying pathology in only 30% of cases, while the remaining cases are found to be benign (reactive, reparative/metaplastic). Previous studies have reported positive ProExC and IMP3 staining in neoplastic glandular(More)
OBJECTIVES K-ras gene product in the mitogen-activated protein kinase/extracellular signal-regulated kinase pathway is critical in the development of certain types of malignancies. K-ras mutation-associated pancreatic and ovarian carcinomas often display mucinous differentiation. Previous studies have shown that k-ras mutation is found in 10% to 30% of(More)
The well-established molecular pathogenesis of chronic myelogenous leukemia (CML) and its consequences for laboratory testing and clinical management illustrate a classic paradigm for the importance of molecular diagnostics in targeted drug therapy. The success of the tyrosine kinase inhibitor (TKI), imatinib, as the currently recommended first-line(More)
Liesagang-like rings (LR) are periodic structures with equally spaced radial striations formed by a process that involves diffusion, nucleation, flocculation or precipitation, and supersaturation. Being more common in vitro, on rare occasions also reported in vivo in association with inflammatory or cystic lesions and confused with parasites or(More)
High-risk human papillomavirus infection usually is seen at one anatomic site in an individual. Rarely, infection at multiple anatomic sites of the female lower genital tract in the same individual is encountered either simultaneously and/or at a later date. The current study identifies the various subtypes of high-risk human papillomavirus infection in(More)
A 73-year-old woman was found to have a 1.7 cm axillary mass, for which a core needle biopsy was performed. The specimen revealed fragmented squamous epithelium surrounded by lymphoid tissue consistent with a squamous inclusion cyst in a lymph node, but a metastatic squamous cell carcinoma could not be excluded. Within one month, the lesion enlarged to 5 cm(More)
