The toroidal plasma rotation generated by the external momentum input and by the plasma itself (intrinsic rotation) has been separated through a novel momentum transport analysis in the JT-60U tokamak device. The toroidal rotation, which is not determined by the momentum transport coefficients and the external momentum input, has been observed. It is found that this intrinsic rotation is locally determined by the local pressure gradient and increases with increasing pressure gradient. This trend is almost the same for various plasmas: low and high confinement mode, co and counterrotating plasmas.

Factors Associated with Prolonged Mechanical Ventilation in Late Repair of Tetralogy of Fallot.
Pediatr Cardiol
January 2025
Pediatric Intensive Care Department, Wolfson Medical Center, Holon, Israel.
Research establishing factors associated with duration of mechanical ventilation after Tetralogy of Fallot repair, is mainly based on population presenting at early infancy. There are fewer reports regarding repair after infancy, during childhood and preadolescence. To compare two groups of late TOF repair based on post-operative invasive mechanical ventilation duration and explore associations with pre-operative clinical markers of severity of right ventricular outflow tract obstruction.

Background: Persistent and mobile organic compounds (PMOC) are of great concern for water quality and human health. The recent improvement and availability of high-resolution mass spectrometry in combination with liquid chromatography have widely expanded the potential of analytical workflows for their detection and quantitation in water. Given their high polarity, the detection of some PMOC requires alternative techniques to reversed-phase chromatography, such as hydrophilic interaction liquid chromatography (HILIC) and supercritical fluid chromatography (SFC).

Bioprosthetic valve fracture for transcatheter aortic valve-in-valve replacement: A systematic literature review.
Ann Thorac Surg
January 2025
Department of Cardiovascular Surgery, Mayo Clinic, Rochester, MN.
Transcatheter aortic valve-in-valve replacement presents a viable, minimally invasive approach to replacing degraded bioprosthetic surgical valves. The major drawback of this technique is poor hemodynamics in the form of patient-prosthesis mismatch and high transvalvular gradients. This is commonly attributable to the reduced valvular diameter from the transcatheter heart valve fixed inside the degraded bioprosthesis.

Comput Biol Med
January 2025
Department of Mathematics and Statistics, The University of Lahore, Lahore Campus, Pakistan. Electronic address:
Glaucoma is an irreversible, progressive, degenerative eye disorder arising because of increased intraocular pressure, resulting in eventual vision loss if untreated. The QSPR relates, mathematically, by employing various algorithms, a specified property of a molecule that arises either from physical, chemical, or biological phenomena using various aspects of its structure. Here in, a similar application based on topological indices and inferences derived from the structure for the calculation of different drug properties like molar refractivity, refractive index, enthalpy, boiling points, molecular weight, and polarizability is presented.
