Bacteriophage TP-13, a converting phage for sporulation and crystal formation in Bacillus thuringiensis, was isolated from soil. The phage converted anoligosporogenic (sporulation frequency, 10(-8), acrystalliferous mutant to spore positive, crystal positive at a high frequency. Each plaque formed by TP-13 in a lawn of sensitive cells contained spores and crystals. These spores were heat stable...

BACKGROUND Protein tyrosine phosphorylation (TP) of human sperm is related to sperm capacitation and zona pellucida (ZP) binding. The aim of this study was to determine whether the TP of capacitated sperm is a useful marker for the ability of sperm to bind to the ZP and undergo the ZP-induced acrosome reaction (AR). METHODS Semen samples were obtained from 115 subfertile men with sperm count ...

BACKGROUND 5-Fluorouracil (5-FU) is the cornerstone of chemotherapeutic treatment for patients with colorectal cancer. The enzyme thymidine phosphorylase (TP) catalyzes the conversion of 5-FU to its active metabolite, 5-fluoro-2'-deoxyuridine. TP is expressed in tumour epithelial cells and stromal cells, particularly in tumour-associated macrophages. These macrophages may affect sensitivity to ...

Background: To the best of our knowledge, there are studies related to QT and QTc interval in patients with hypocalcemia, but no evaluating T wave peak end (Tp-e interval), Tp-e/QT Tp-e/QTc ratios used evaluate cardiac arrhythmia risk ventricular repolarization changes rates. Objectives: Therefore, we aimed investigate whether is a change Tp-e interval, hypocalcemia. Methods: Retrospectively, 2...

BACKGROUND High mobility group box 1 (HMGB1) plays important roles in a large variety of diseases; glycyrrhizin (GL) is recognized as an HMGB1 inhibitor. However, few studies have focused on whether glycyrrhizin can potentially improve the outcome of traumatic pancreatitis (TP) by inhibiting HMGB1. METHODS A total of 60 male Wistar rats were randomly divided into three groups (n = 20 in each)...
