Inventive Methods Used to Study and Control Thermal Necrosis: A Review [PDF]

Journal of Clinical and Diagnostic Research, 2020
Orthopedic surgeries use screw and plate fixations. Bone drilling is performed for smooth and minimum damage to bone surface during screw insertion. Bone drilling creates a hole with circular cross-section.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Development of a New Forced Cooling Technology Using a High-Pressure Coolant for Machining Difficult-To-Machine Materials

Journal of Manufacturing and Materials Processing, 2018
In recent years, titanium and nickel alloys have become relevant in the production of aeronautic and astronautic parts. Since both nickel and titanium alloys have a very small thermal conductivity, the used tool will suffer huge damage from the heat ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Influence of cutting fluid on tool edge temperature in end milling titanium alloy

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015
This study investigates the influence of cutting fluid on the cutting temperature in end milling of a titanium alloy. As the cutting temperature, the tool edge temperature was measured using a two-color pyrometer with an optical fiber.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
