Effectively α-Terpineol Suppresses Glioblastoma Aggressive Behavior and Downregulates KDELC2 Expression.

Background: Glioblastoma (GBM) is notorious for the aggressive behaviors and easily results in chemo-resistance. Studies have shown that the use of herbal medicines as treatments for GBM as limited by the blood-brain barrier (BBB) and glioma stem cells.

Purpose: The aim of this study was to investigate the relationship between GBM suppression and α-terpineol, the monoterpenoid alcohol derived from Eucalyptus glubulus and Pinus merkusii.

Differentiation between dysplastic nodule and early-stage hepatocellular carcinoma: the utility of conventional MR imaging.

Aim: To elucidate the variety of ways early-stage hepatocellular carcinoma (HCC) can appear on magnetic resonance (MR) imaging by analyzing T1-weighted, T2-weighted, and gadolinium-enhanced dynamic studies.

Methods: Seventy-three patients with well-differentiated HCC (wHCC) or dysplastic nodules were retrospectively identified from medical records, and new histological sections were prepared and reviewed. The tumor nodules were categorized into three groups: dysplastic nodule (DN), wHCC compatible with Edmondson-Steiner grade I HCC (w1-HCC), and wHCC compatible with Edmondson-Steiner grade II HCC (w2-HCC).

The clinicopathological analysis of 303 cases with malignant lymphoma classified according to the World Health Organization classification system in a single institute of Taiwan.

Several reports have shown a different distribution of malignant lymphoma (ML) in Asian and Western populations. The purpose of our survey was to elucidate whether there are substantial differences in the frequencies of subtypes of ML between different geographical areas. All entities diagnosed as ML between June 1995 and December 2007 were selected according to the 2008 World Health Organization (WHO) classification and searched for clinical outcomes.

Serum prohepcidin levels correlate with hepatic iron stores in chronic hepatitis C patients.

Background/aims: Increased serum iron indices and hepatic iron stores are frequent in patients with chronic hepatitis C (CHC). The antimicrobial peptide hepdicin produced in the liver plays a pivotal role in iron homeostasis.

Methodology: To determine the expression of hepcidin, the serum levels of prohepcidin were measured in 58 CHC patients and 144 healthy controls.

MR imaging of primary spinal germinoma: a case report and review of the literature.

Germinomas in the central nervous system (CNS) are uncommon tumors and occur usually in the pineal or suprasellar regions. Primary spinal germinoma is extremely rare. Here we reported a rare case of an extramedullary germinoma in a young adult who presented with progressive paraparesis and retention of stool and urine.

RARRES1 expression is significantly related to tumour differentiation and staging in colorectal adenocarcinoma.

Retinoic acid receptor responder 1 (RARRES1) is a retinoid regulated gene. Its expression is frequently down-regulated through DNA hypermethylation in several types of malignant tissues. This study investigated the clinical significance of RARRES1 protein and its association with RARRES3 protein expression in 161 (26 adenoma, 13 distal normal mucosa and 122 primary colorectal adenocarcinoma) paraffin-embedded colorectal tissues by immunohistochemistry.

Malignant phyllodes tumor of the prostate.

We report the case of a 47-year-old male patient who suffered from a malignant phyllodes tumor of the prostate with invasion to the rectum and urinary bladder. The local recurrence at the left scrotum was identified 6 years after radical cystoprostatectomy. Another 2 years after radical orchiectomy showed no evidence of secondary local recurrence or distant metastasis.

Expression and regulation of retinoid-inducible gene 1 (RIG1) in breast cancer.

Background: Retinoid-inducible gene I (RIG1) is a growth regulator protein that exhibits activities to suppress cellular growth and induce cellular differentiation and apoptosis. This study analyzed the expression and regulation of RIG1 in breast cancer cells in vitro and in vivo.

Materials And Methods: Expression of RIG1 RNA in breast cancer tissues was analyzed using RNA in situ hybridization.

Decreased expression of type II tumor suppressor gene RARRES3 in tissues of hepatocellular carcinoma and cholangiocarcinoma.

Aim: To analyze the expression of retinoic acid receptor responder 3 (RARRES3) protein in paraffin-embedded tissues of hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC), and the correlation of RARRES3 production with tumor differentiation.

Methods: Expression of RARRES3 in tissues from 21 CC (10 well-, 7 moderately- and 4 poorly-differentiated) and 32 HCC was determined by immunohistochemistry.

Results: Among 21 CC tissues, RARRES3 was detected in 8 (80%) of 10 well-differentiated tumors.

Histologic and immunohistochemical study of bone marrow monocytic nodules in 21 cases with myelodysplasia.

Previously, 4 cases of myelodysplastic syndrome were reported that had unusual, distinct monocytic nodules in bone marrow. The monocytic nodules, predominantly composed of monocytes with CD68+ immunostaining, had no or low expression of Ki-67 and topoisomerase II alpha. The purpose of the present study was to further define the associated clinical diseases, histologic features, and immunohistochemical characteristics of 21 such cases.

Unusual epithelium in a subpubic sinus.

A 5-year-old male presented with the history of whitish discharge from a midline sinus opening just above the pubis for 2 months. Attempted radiography of the sinus revealed a blind fistula and voiding cystourethrography was normal. The fistula was excised deep to the subpubic space without any evidence of connection to the lower urinary tract.
