Impact of calcification on Murray law-based quantitative flow ratio for physiological assessment of intermediate coronary stenoses

Cardiology Journal
BACKGROUND: To investigate the influence of coronary calcification on the diagnostic performance of Murray law-based quantitative flow ratio (μQFR) in identifying hemodynamically significant coronary lesions referenced to fractional flow reserve (FFR ...

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Factor Analysis of Net Cash Flow Margin Ratio

, 2019
The study object is net cash flow or profit margin ratios within a company. Sometimes it is very difficult to reveal and identify the factors that affect the net cash flow margin. Cash flow ratio within a company is analyzed.

Flow boiling characteristics in high aspect ratio microchannel: pure liquid and binary mixtures with the effect of flow orientation

Although the implementation of flow boiling in mini/microscale thermal management systems offers great advantages, several fundamental challenges need to be resolved, such as the impact of operating conditions on the characteristics.

Delivery of DNA‐encoded vaccines and proteins in mice using cutaneous suction‐mediated transfection

FEBS Open Bio, EarlyView.
Cutaneous suction‐mediated transfection in mice for delivery of DNA‐encoded vaccines and proteins. A critical limitation of DNA vaccines and other therapeutics is transfection in vivo to produce the encoded antigens or therapeutic proteins. Cutaneous suction‐based methods have demonstrated effectiveness in many animal models and have been successfully ...

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Ultrasonic flow ratio measured immediately after successful rotational atherectomy with stent implantation predicts major adverse cardiovascular events

Frontiers in Cardiovascular Medicine
IntroductionThe potential role of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) and ultrasonic flow ratio (UFR) in predicting adverse outcomes in patients with successful rotational atherectomy (RA) and stent placement ...

Heterotropic regulation and negative homotropic cooperativity

FEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Predictive value of the inconsistency between the residual and post-PCI QFR for prognosis in PCI patients

Frontiers in Cardiovascular Medicine
IntroductionTo investigate the prognostic value of the consistency between the residual quantitative flow ratio (QFR) and postpercutaneous coronary intervention (PCI) QFR in patients undergoing revascularization.MethodsThis was a single-center ...
