The 6-minute walk test (T6) is used to assess cardiopulmonary diseases due to its prognosis capacity, easy performance and reproducibility. Pulmonary hypertension (PH) is defined and classified as a hemodynamic consequence leading to increased pulmonary arterial pressure and may result in right ventricular failure and consequent death. This case reports the prescription of T6 by the cardiology ...

Phage T6 was used as a label to follow the growth of the outer membrane in a strain of Escherichia coli temperature sensitive for the production of the T6 receptor. Extension of the surface takes place at the cell poles. Small cells extend at only one pole, whereas larger cells grow from both poles. The change from unipolar to bipolar growth appears to depend on the attainment of a particular c...

Cell walls of E. coli strains B and Cullen contain specific receptors for colicin K and for the T2, T6, and C16 phages. The receptors for the bacteriocin and the T6 virus are located in the outer layers of the cell wall of these microorganisms and are absent in their cytoplasmic membrane. The receptors for colicin K, phage T2, and the T6 and C16 viruses differ in their stability toward enzymes ...

In this research work, an experimental evaluation was conducted to explore the fretting fatigue life of multilayer Cr–CrN-coated AL7075-T6 alloy specimens with higher adhesion strength to substrate as the coating adhesion strength is one of the most critical issues in magnetron sputtering technique. Physical vapor deposition (PVD) magnetron sputtering technique was used for coating purpose, and...

AIM To evaluate the efficacy of intravitreal dexamethasone injections in diabetic macular edema (DME). METHODS A 700 μg slow-release intravitreal dexamethasone implant (Ozurdex®) was placed in the vitreal cavity of 17 patients (19 eyes) affected with persistent DME. Best corrected visual acuity (BCVA) was assessed through Early Treatment Diabetic Retinopathy Study (ETDRS). Central macular thi...

The deoxyribonucleic acid of the T-even coliphages contains glucosylated and nonglucosylated 5-hydroxymethylcytosine in place of cytosine (l-6). In the case of deoxyribonucleic acid from phage T6, 72y0 of the 5-hydroxymethylcytosine residues are diglucosylated. In T2 deoxyribonucleic acid, 70% of the 5-hydroxymethylcytosine residues are monoglucosylated, but 5% bear diglucosyl units. A recent i...

The Charpy impact energy of A356 alloys has been measured. Instrumented Charpy impact tests have been conducted at 25, 100, 150, and 200 ~ The Charpy specimens were machined from plate castings or tapered cylindrical castings. The plates were produced in sand molds, and tapered cylinders were produced in water-cooled copper molds. Both unmodified and strontium-modified castings were tested. The...

Hepatic fibrogenesis involves the activation of hepatic stellate cells (HSCs), which synthesize excess extracellular matrix and contribute to the development of liver fibrosis. In a prior study we tested the effect of combined treatment with taurine, epigallocatechin gallate and genistein on the development of alcohol-induced liver fibrosis in vitro. In this study, the biological activity of th...

This study aims to investigate the flow and fracture behavior of aluminum alloy 6082-T6 (AA6082-T6) at different strain rates and triaxialities. Two groups of Charpy impact tests were carried out to further investigate its dynamic impact fracture property. A series of tensile tests and numerical simulations based on finite element analysis (FEA) were performed. Experimental data on smooth speci...

Diabetes mellitus leads to increased Advanced Glycation End Products (AGE) production, which has been associated with secondary diabetic complications. Type 1 diabetic patients undergoing pancreas-kidney transplantation (SPKT) can restore normoglycemia and renal function, eventually decreasing AGE accumulation. We aimed to prospectively study AGE evolution after SPKT. Circulating AGE were asses...
