A heat-stable enterotoxin produced by Vibrio mimicus (VM-ST) was studied. VM-ST was purified from a culture supernatant of V. mimicus strain AQ-0915 by ammonium sulfate fractionation, hydroxyapatite treatment, ethanol extraction, column chromatography on both SP-Sephadex C-50 and DEAE-Sephadex A-25, and HPLC, and the recovery rate was about 15%. Purified VM-ST was heat-stable. VM-ST activity wa...

Pulse wave velocity (PWV) was recorded in different arterial segments in 25 male normal healthy individuals, before, during and after Valsalva maneuver (VM). Heart rate (HR) and blood pressure (BP) showed significantly significant (P < 0.001) variation in phase II and IV of VM compared to baseline. PWV in aorta to femoral (AO-Fem) arterial segment revealed progressive increase from baseline to ...

BACKGROUND When performing the Valsalva maneuver (VM), adults and preadolescents produce the same expiratory resistance values. OBJECTIVE To analyze heart rate (HR) in preadolescents performing VM, and propose a new method for selecting expiratory resistance. METHOD The maximal expiratory pressure (MEP) was measured in 45 sedentary children aged 9-12 years who subsequently performed VM for ...

We used two experimental techniques to study the effect of lidocaine hydrochloride on the early inward transient (sodium) current as it is reflected by the maximum rate of change of action potential phase 0 (Vmax). We assessed the effect of lidocaine on Vmax as Purkinje fibers were slowly depolarized by increasing the extracellular potassium concentration from 4.0 to 16.0 mM; these voltage-depe...

In order to evaluate the performance of biofilter for H2S removal from contaminated air, a 120×14 cm column biofilter was constructed using clear polyacrylic material in conjunction with H2S production and control systems. The column was divided into four stages using perforated plates. The column was packed with a mixture of mushroom compost and snail shell (4:1).&#10 The performance of biofil...

Public cloud providers lease virtual machines(VM) on a server to customers. This model makes it easier for cloud providers to manage their infrastructure. However, on the other hand, it presents the customers with difficulty in terms of manually selecting the VM instance type. The inherent performance heterogeneity observed in public clouds further leads to the uncertainty of VM performance obs...

Vasculogenic mimicry (VM) has increasingly been recognized as a form of angiogenesis. In VM, epithelial cells are integrated into the malignant tumor vasculature. An association has been observed between VM and poor clinical prognosis in some malignant tumors. However, whether VM is present and clinically significant in hepatocellular carcinoma (HCC) is unknown. In this study, we determined whe...
