Hard clam extracts induce atypical apoptosis in human gastric cancer cells.

Hard clams (HCs) are a nutritionally high-quality and popular seafood, and are established to be a potent antitumor food. The aim of the present study was to determine whether HC extracts induce apoptosis in the human gastric cancer cell line, AGS. In contrast with previously reported methods of extraction, crude extracts of HC were obtained by freezing and thawing and by a method free of hot water or organic solvents.

Evaluation of cellular retinoic acid binding protein 2 gene expression through the retinoic acid pathway by co-incubation of Blastocystis ST-1 with HT29 cells in vitro.

Blastocystis is a parasitic protist with a worldwide distribution that is commonly found in patients with colon and gastrointestinal pathological symptoms. Blastocystis infection has also commonly been reported in colorectal cancer and HIV/AIDS patients with gastrointestinal symptoms. To understand the pathway networks of gene regulation and the probable mechanisms influencing functions of HT-29 host cells in response to parasite infection, we examined the expression of 163 human oncogenes and kinases in human colon adenocarcinoma HT-29 cells co-incubated with Blastocystis by in-house cDNA microarray and PCR analysis.

Changes of immunogenic profiles between a single dose and one booster influenza vaccination in hemodialysis patients - an 18-week, open-label trial.

Annual influenza vaccination is recommended, but its efficacy in dialysis population is still controversial. Here we aimed to compare the dynamic changes of immune response between various influenza vaccination protocols in hemodialysis patients. A 18-week open label, non-randomized, controlled trial was conducted during 2011-2012.

The role of echocardiographic study in patients with chronic kidney disease.

Despite the recent enormous advances in medicine, high mortality and morbidity rates among the chronic kidney disease (CKD) patients remain an important but unresolved issue. Cardiovascular disease is a major cause of mortality and morbidity in patients with CKD. Abnormal left ventricular geometry and functions are common in this patient group and have been proven to be correlated with a high cardiovascular mortality/morbidity and all-cause mortality.

Distinct DNA methylation epigenotypes in bladder cancer from different Chinese sub-populations and its implication in cancer detection using voided urine.

Background: Bladder cancer is the sixth most common cancer in the world and the incidence is particularly high in southwestern Taiwan. Previous studies have identified several tumor-related genes that are hypermethylated in bladder cancer; however the DNA methylation profile of bladder cancer in Taiwan is not fully understood.

Methods: In this study, we compared the DNA methylation profile of multiple tumor suppressor genes (APC, DAPK, E-cadherin, hMLH1, IRF8, p14, p15, RASSF1A, SFRP1 and SOCS-1) in bladder cancer patients from different Chinese sub-populations including Taiwan (104 cases), Hong Kong (82 cases) and China (24 cases) by MSP.
