Aberrant activation of nuclear factor of activated T cell 2 in lamina propria mononuclear cells in ulcerative colitis.

Aim: To investigate the role of nuclear factor of activated T cell 2 (NFAT2), the major NFAT protein in peripheral T cells, in sustained T cell activation and intractable inflammation in human ulcerative colitis (UC).

Methods: We used two-dimensional gel-electrophoresis, immunohistochemistry, double immunohistochemical staining, and confocal microscopy to inspect the expression of NFAT2 in 107, 15, 48 and 5 cases of UC, Crohn's disease (CD), non-specific colitis, and 5 healthy individuals, respectively.

Results: Up-regulation with profound nucleo-translocation/activation of NFAT2 of lamina propria mononuclear cells (LPMC) of colonic mucosa was found specifically in the affected colonic mucosa from patients with UC, as compared to CD or NC (P < 0.

Identification of collapsin response mediator protein-2 as a potential marker of colorectal carcinoma by comparative analysis of cancer cell secretomes.

The cancer cell secretome may contain many potentially useful biomarkers. We therefore sought to identify proteins in the conditioned media of colorectal carcinoma (CRC) cell lines but not in those from other cancer cell lines. The secretomes of 21 cancer cell lines derived from 12 cancer types were analyzed by SDS-PAGE combined with MALDI-TOF MS.

Cellular neurothekeoma with melanocytosis.

Cellular neurothekeoma (CNT) is a benign dermal tumor mainly affecting the head and neck and the upper extremities. It is characterized histologically by interconnecting fascicles of plump spindle or epithelioid cells with ample cytoplasm infiltrating in the reticular dermis. The histogenesis of CNT has been controversial, although it is generally regarded as an immature counterpart of classic/myxoid neurothekeoma, a tumor with nerve sheath differentiation.

Immunohistochemical expression of OCT4 in primary central nervous system germ cell tumours.

OCT4 is a POU-domain transcription factor that is expressed in embryonic stem cells and germ cells. OCT4 has been detected in specific types of testicular germ cell tumour (GCT), including seminoma and embryonal carcinoma. The aim of this study was to evaluate the role of OCT4 expression in the diagnosis of primary central nervous system (CNS) pure and mixed GCT.

Long-term changes in trace elements in patients undergoing chronic hemodialysis.

Although the connection between aluminum intoxication and dialysis dementia was identified in the 1980s, understanding of trace element imbalances in hemodialysis patients is as yet incomplete. Recent application of newer inductively coupled plasma-mass spectrometry (ICP/MS) techniques has resulted in renewed study of this population. We used ICP/MS to evaluate serum concentrations of Cu, Se, Zn, Mn, and Ni in a relatively large population of hemodialysis patients compared with healthy age-matched controls.

Diagnosis of nodal Langerhans cell histiocytosis by fine needle aspiration cytology.

Langerhans cell histiocytosis (LCH) is a rare disease and disease confined to the lymph nodes is even more uncommon. Fine needle aspiration (FNA) cytology of LCH of the lymph nodes has rarely been described. A case study of LCH of the lymph nodes in a 23-year-old man is presented.

Medial canthal tophus associated with gout.

Purpose: To report a case with a gouty tophus at the medial canthus.

Design: Observational case report.

Methods: Review of the clinical, laboratory, photographic, and pathologic records of a patient with a gouty tophus at the medial canthus.

Macrocystic serous cystadenoma of the pancreas in a young patient resembling a pseudocyst: case report and literature review.

Macrocystic serous cystadenoma is an unusual and essentially benign pancreatic tumor. Ages of reported cases are usually 60 years and over, with a mean age of 54 years. Herein, we report on a 26-year-old man who presented with upper abdominal pain.

Pathological analysis of congenital cervical cysts in children: 20 years of experience at Chang Gung Memorial Hospital.

Background: Congenital cervical cysts are frequently encountered in pediatric populations, and constitute one of the most intriguing areas of pediatric pathology. This report analyzes cervical cysts in Taiwanese children diagnosed at Chang Gung Memorial Hospital (CGMH) over the past 20 years. The pathologic and clinical findings are reviewed.
