Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.

The Impact and Reliability of Tissue Segmentation on In Vivo Magnetic Resonance Spectroscopy Metabolite Quantification

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Quantification of metabolite concentrations using MRS requires tissue‐dependent signal corrections. Accurate estimation of voxel tissue composition is therefore essential. Commonly used brain tissue segmentation tools differ in their algorithms and implementation, potentially introducing variability in MRS‐derived concentration ...

GABA+‐Edited Magnetic Resonance Spectroscopy Deep Learning Quality Assessment Framework

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Motivated by the need to improve GABA+‐edited magnetic resonance spectroscopy (MRS) quality, we developed a three‐module framework to improve transient averaging based on quality. We hypothesized that training a deep learning (DL) model to differentiate spectrum quality could improve transient averaging compared to traditional ...

Influence of dietary intake and eating patterns on reactive hypoglycemic events in patients postesophagectomy: A prospective observational study using continuous glucose monitoring

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Esophagectomy causes anatomical changes that can lead to rapid food transit and reactive hypoglycemia (RH). Patients are advised on eating patterns postesophagectomy to prevent RH, but its true incidence and the impact of dietary recommendations remain under‐researched.

Safety Evaluation of an Aqueous Root and Leaf Extract of Ashwagandha (Withania somnifera)

open access: yesPhytotherapy Research, EarlyView.
Sensoril, an aqueous root and leaf extract of ashwagandha showed no evidence of mutagenicity in the in vitro Ames assay, was negative in the in vitro micronucleus, in vivo mammalian bone marrow chromosome aberration assays, and was well tolerated in the rat at up to 4000 mg/kg BW/day when administered orally for a period of 90 days. The data from these

Creep Performance of Stainless Steel 316 Brackets: Insights From Conventional and Advanced Modeling Approaches

open access: yessteel research international, EarlyView.
Creep behavior of SS 316 brackets is examined through experiments, conventional creep laws, and advanced constitutive modeling. Long‐term deformation, stress redistribution, and life prediction are compared under service‐relevant loads. The study highlights the limits of classical models and demonstrates improved accuracy using advanced approaches for ...
