Using Shockwave Lithotripsy to Treat Severe Calcified Mitral Stenosis in a Pregnant Woman

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Rheumatic mitral stenosis (MS) with significant calcification presents challenges for both surgical and transcatheter interventions. Percutaneous balloon mitral valvuloplasty (PBMV) is often limited in these cases due to valve rigidity, increasing the risk of mitral regurgitation (MR).

Dataset of human skin and fingernails images for non-invasive haemoglobin level assessment

Scientific Data
Anaemia, a decrease in total concentration of haemoglobin (Hb) in blood, affects substantial percentage of the population worldwide. Currently, the gold standard for determining the Hb level is the invasive analysis of venous blood.

Evolutionary Conditions in the Dissipative MHD System Revisited

, 2007
The evolutionary conditions for the dissipative continuous magnetohydrodynamic (MHD) shocks are studied. We modify Hada's approach in the stability analysis of the MHD shock waves.

Unstable magnetohydrodynamical continuous spectrum of accretion disks. A new route to magnetohydrodynamical turbulence in accretion disks [PDF]

, 2007
We present a detailed study of localised magnetohydrodynamical (MHD) instabilities occuring in two--dimensional magnetized accretion disks. We model axisymmetric MHD disk tori, and solve the equations governing a two--dimensional magnetized accretion ...

Influence of Magnetic Helicity in MHD [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractObservations have shown that the Sun's magnetic field has helical structures. The helicity content in magnetic field configurations is a crucial constraint on the dynamical evolution of the system. Since helicity is connected with the number of links we investigate configurations with interlocked magnetic flux rings and one with unlinked rings.

Influence of Low Magnetic Fields on Hydrogen Evolution Reaction Performance of NiCoP Electrocatalysts

ChemPhysChem, EarlyView.
Herein, electrocatalytic activity enhancement is reported of NiCoP nanorods by applying an external magnetic field. The NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm−2 without magnetic field. However, under low magnetic field of 2000 G, the overpotential reduces to 62 mV at 10 mA cm−2 in 0.5 M H2SO4, demonstrating that external magnetic

Identification and Investigation of the Intrinsic Receptor Activation Potential and Metabolization of the New Oxo‐Pyridyl Synthetic Cannabinoid Receptor Agonist CH‐FUBBMPDORA

Drug Testing and Analysis, EarlyView.
Another Chinese generic ban‐evading SCRA, CH‐FUBBMPDORA, has emerged. This study reports its first identification in Europe, its analytical characterization (NMR, Raman, FTIR, GC–MS, and HRMS), its cannabinoid activation potential in a βarr2 recruitment assay, and its metabolization profile.

Compressible MHD in Spherical Geometry [PDF]

International Astronomical Union Colloquium, 1991
AbstractThe generation of magnetic field by a conducting, compressible fluid inside a spherical shell is studied by direct numerical simulations. A pseudo-spectral method is used in order to resolve accurately all the scales present in the problem. The range of parameters considered is the following: a unit Prandtl number, Rayleigh numbers up to 100 ...
