Detection of Tumor Cell-Specific mRNA in the Peripheral Blood of Patients with Breast Cancer-Evaluation of Several Markers with Real-Time Reverse Transcription-PCR [PDF]

open access: yes, 2013
It is widely known that cells from epithelial tumors, e. g., breast cancer, detach from their primary tissue and enter blood circulation. We show that the presence of circulating tumor cells (CTCs) in samples of patients with primary and metastatic ...

Experimental and numerical investigations on effect of reverse flow on transient from forced circulation to natural circulation

open access: yesNuclear Engineering and Technology, 2020
In a sudden shutdown of primary pump or coolant loss accident in a marine nuclear power plant, the primary flow decreases rapidly in a transition process from forced circulation (FC) to natural circulation (NC), and the lower flow enters the steam ...

High Coronary Collateral Circulation Increases Left Ventricular Reverse Remodeling Event in Patients with Chronic Ischaemic Heart Disease Underwent Coronary Artery Bypass Surgery

open access: yesMajalah Kardiologi Indonesia, 2021
Background: Coronary collateral circulation (CCC) is linked to myocardial remodeling severity in patients with chronic ischaemic heart disease (IHD). However its effect on left ventricular reverse remodeling (LVRR) in patients with chronic IHD underwent ...

Reversal of Hepatic Venous Circulation in Dogs

open access: yesAnnals of Surgery, 1958
Conclusions1. Dogs survive for prolonged periods, at least 57 days, following reversal of their hepatic venous circulation. 2. Crimped teflon vascular prostheses remain patent in these low pressure venous systems and function satisfactorily enough to achieve objectives of this experiment. 3. This experimental preparation is presented as one potentially

Design and numerical analysis of a large‐diameter air reverse circulation drill bit for reverse circulation down‐the‐hole air hammer drilling

open access: yesEnergy Science & Engineering, 2019
Reverse circulation down‐the‐hole (RC‐DTH) air hammer drilling is a fast and cost‐effective method for hard rock drilling. As the air RC drill bit is the heart for RC‐DTH air hammer drilling system to form the reverse circulation, a large‐diameter RC ...

Modeling Turbulent Flow in Stirred Tanks with CFD: The Influence of the Modeling Approach, Turbulence Model and Numerical Scheme [PDF]

open access: yes, 2004
Single phase turbulent flow in a tank stirred by a down- and an up-pumping pitched blade turbine has been simulated using CFD. The effect of the modeling approach, discretization scheme and turbulence model on mean velocities, turbulent kinetic energy ...
