Gut microbiota microbial metabolites in diabetic nephropathy patients: far to go.

Diabetic nephropathy (DN) is one of the main complications of diabetes and a major cause of end-stage renal disease, which has a severe impact on the quality of life of patients. Strict control of blood sugar and blood pressure, including the use of renin-angiotensin-aldosterone system inhibitors, can delay the progression of diabetic nephropathy but cannot prevent it from eventually developing into end-stage renal disease. In recent years, many studies have shown a close relationship between gut microbiota imbalance and the occurrence and development of DN.

Roles of cancer stem cells in gastrointestinal cancers.

Cancer stem cells (CSCs) are the main cause of tumor growth, invasion, metastasis and recurrence. Recently, CSCs have been extensively studied to identify CSC-specific surface markers as well as signaling pathways that play key roles in CSCs self-renewal. The involvement of CSCs in the pathogenesis of gastrointestinal (GI) cancers also highlights these cells as a priority target for therapy.

Detection of clarithromycin-resistant Helicobacter pylori in clinical specimens by molecular methods: A review.

Various molecular methods have been developed to rapidly detect clarithromycin (CLR) resistance in Helicobacter pylori isolates in clinical specimens. All of these assays for detecting CLR resistance in H. pylori are based on detection of mutations in the 23S rRNA gene.

Overexpression of integrin αv in the human nasopharyngeal carcinoma associated with metastasis and progression.

Background: Integrins are cell-surface adhesion molecules, regulate normal cellular interactions, and which are consisting of α and β subunits and facilitate signal transduction in a bidirectional manner. Tumor cells have been found to express a wide variety of integrins, overexpression of integrin αv has been detected in a growing number of human malignancy types, However, the reports obout expression of integrin αv in nasopharyngeal carcinoma (NPC) are very rare.

Objective: This study aims to detect the expression of integrin αv in NPC, and to evaluate the correlation between integrin αv expression and clinicopathological factors.

Enzymic colorimetry-based DNA chip: a rapid and accurate assay for detecting mutations for clarithromycin resistance in the 23S rRNA gene of Helicobacter pylori.

Macrolide drugs, such as clarithromycin (CAM), are a key component of many combination therapies used to eradicate Helicobacter pylori. However, resistance to CAM is increasing in H. pylori and is becoming a serious problem in H.
