LAB-STEM CELLS

INTRODUCTION: Recent evidence suggests that glioblastoma is driven by a subset of tumor initiating (TI) cells characterized by their capacity to form tumors in xenograft models and self-renew in vitro. These TI cells share many properties of neural stem/progenitor cells, including the expression of certain cell surface markers. With serial passage, many cells lose their capacity to ...

Mycotic Aneurysm Due to Non-typhi Salmonella: Report of 16 Cases

From 1990 through 1994, we collected information on all cases of mycotic aneurysms due to non-typhi Salmonella that occurred at the Veterans General Hospital in Kaohsiung, Taiwan. All cases of salmonella bacteremia were reviewed to find any additional cases. A total of 16 cases of salmonella mycotic aneurysms occurred. The mortality rate was 100% among the three patients treated ...

Skin and Soft-Tissue Manifestations of Shewanella putrefaciens Infection

Shewanella putrefaciens, a saprophytic gram-negative rod, is infrequently recovered from clinical specimens. Although a number of clinical syndromes have been attributed to S. putrefaciens, the pathogenic role of this agent remains largely undefined. We report 16 cases of S. putrefaciens infection that occurred at the Veterans General Hospital—Kaohsiung in Taiwan between 1990 and ...

The Effect of Tenidap on Cytokines, Acute-Phase Proteins, and Virus Load in Human Immunodeficiency Virus (HIV)-Infected Patients: Correlation between Plasma HIV-1 RNA and Proinflammatory Cytokine Levels

Proinflammatory cytokines may be important in the pathogenesis of human immunodeficiency virus type 1 (HIV-1) disease. Tenidap decreases interleukin (IL)-6, IL-1, and tumor necrosis factor (TNF) production by peripheral blood mononuclear cells and decreases IL-6 plasma levels in rheumatoid arthritis patients. In this randomized double-blind study, 43 HIV-1-infected patients ...

Role of Benzathine Penicillin G in Prophylaxis for Recurrent Streptococcal Cellulitis of the Lower Legs

Cellulitis of the lower leg is an infection caused by streptococci or, less commonly, Staphylococcus aureus and other gram-negative rods. Recurrence of cellulitis is a common problem. In the present study, we evaluated the use of monthly intramuscular injections of benzathine penicillin G to prevent recurrences of cellulitis. A total of 115 patients with definite or presumptive ...

CKD-MBD - A

Introduction and Aims:In patients with chronic renal failure, secondary hyperparathyroidism (sHPT) sometimes requires parathyroidectomy. Prospectively, we compared total parathyroidectomy without autotransplantation and without thymectomy (tPTX) with subtotal parathyreoidectomy with thymectomy (sPTX) for renal hyperparathyroidism. Methods:From 11/2004 to 11/2008, 43 consecutive ...

Significance of platelet activation in vascular access survival of haemodialysis patients

Background. Vascular access failure is the most common cause of morbidity and hospitalization in haemodialysis (HD) patients. Although there are reports that anti‐platelet agents can prevent vascular access thrombosis, the relationship between platelet activation and vascular access failure is not clear. The aim of this study was to investigate the role of platelet activation in ...

Extracellular zinc and ATP-gated P2X receptor calcium entry channels: New zinc receptors as physiological sensors and therapeutic targets

In this review, we focus on two attributes of P2X receptor channel function, one essential and one novel. First, we propose that P2X receptors are extracellular sensors as well as receptors and ion channels. In particular, the large extracellular domain (that comprises 70% of the molecular mass of the receptor channel protein) lends itself to be a cellular sensor. Moreover, its ...

An unusual function of RON receptor tyrosine kinase as a transcriptional regulator in cooperation with EGFR in human cancer cells

Homodimerization of RON (MST1R), a receptor tyrosine kinase, usually occurs in cells stimulated by a ligand and leads to the downstream activation of signaling pathways. Here we report that bladder cancer cells, in response to physiological stress, use an alternative mechanism for signaling activation. Time-course studies indicated that RON migrated directly from the membrane to ...

Anesthetic Propofol Reduces Endotoxic Inflammation by Inhibiting Reactive Oxygen Species-regulated Akt/IKKβ/NF-κB Signaling

Background Anesthetic propofol has immunomodulatory effects, particularly in the area of anti-inflammation. Bacterial endotoxin lipopolysaccharide (LPS) induces inflammation through toll-like receptor (TLR) 4 signaling. We investigated the molecular actions of propofol against LPS/TLR4-induced inflammatory activation in murine RAW264.7 macrophages. Methodology/Principal Findings ...

Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy Improves Survival of Patients with Peritoneal Carcinomatosis from Gastric Cancer: Final Results of a Phase III Randomized Clinical Trial

Background This randomized phase III study was to evaluate the efficacy and safety of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of peritoneal carcinomatosis (PC) from gastric cancer. Methods Sixty-eight gastric PC patients were randomized into CRS alone (n = 34) or CRS + HIPEC (n = 34) receiving cisplatin 120 mg and ...

Genomes of the rice pest brown planthopper and its endosymbionts reveal complex complementary contributions for host adaptation

Background The brown planthopper, Nilaparvata lugens, the most destructive pest of rice, is a typical monophagous herbivore that feeds exclusively on rice sap, which migrates over long distances. Outbreaks of it have re-occurred approximately every three years in Asia. It has also been used as a model system for ecological studies and for developing effective pest management. To ...

Low Serum Creatine Kinase Levels in Breast Cancer Patients: A Case-Control Study

Background Previous studies provide an ambiguous picture of creatine kinase (CK) expression and activities in malignancy. The aim of this study was to investigate the role of serum CK level in breast cancer patients. Patients and Methods 823 female patients diagnosed with breast cancer were consecutively recruited as cases, and 823 age-match patients with benign breast disease were ...

Cancer stem cells in glioblastoma—molecular signaling and therapeutic targeting

Glioblastomas (GBMs) are highly lethal primary brain tumors. Despite current therapeutic advances in other solid cancers, the treatment of these malignant gliomas remains essentially palliative. GBMs are extremely resistant to conventional radiation and chemotherapies. We and others have demonstrated that a highly tumorigenic subpopulation of cancer cells called GBM stem cells ...

GPR48, a poor prognostic factor, promotes tumor metastasis and activates β-catenin/TCF signaling in colorectal cancer

G-protein-coupled receptor 48 (GPR48) is an orphan receptor belonging to the G-protein-coupled receptors family, which plays an important role in the development of various organs and cancer development and progression such as gastric cancer and colorectal cancer (CRC). However, the prognostic value of GPR48 expression in patients with CRC has not been reported. In this study, we ...
