Calibration-Free Estimation of Cerebrovascular Reactivity From Resting-State BOLD fMRI Using Reconstructed Respiratory Fluctuations. [PDF]

Magn Reson Med
ABSTRACT Purpose Cerebrovascular reactivity (CVR) provides an important index of vascular health and is conventionally quantified using a hypercapnic gas or breath‐hold challenge in conjunction with blood‐oxygen‐level‐dependent functional magnetic resonance imaging (BOLD‐fMRI).

Supraphysiological ascorbic acid infusion attenuates cerebrovascular dysfunction in middle-aged and older adults. [PDF]

Physiol Rep
Young (Y) and middle‐aged and older (MA/O) community‐dwelling adults were recruited and randomized to acute ascorbic acid (AA) or saline (SAL) infusions, on separate days. Cerebrovascular reactivity (CVR) to transient hypercapnia (30 s) in the internal carotid artery (ICA), or sustained hypercapnia (3 min) in the middle cerebral artery (MCA), was ...

Craniofacial Morphology and Dental Age Assessment in Pediatric Craniosynostosis: A Comparative Cross-Sectional Study. [PDF]

Clin Exp Dent Res
ABSTRACT Objectives To delineate the craniofacial morphometric characteristics of Thai children with syndromic (SC) and non‐syndromic craniosynostosis (NSC) and to assess dental maturation relative to Chronological Age (CA). Methods This comparative cross‐sectional study evaluated 19 patients (SC: n = 13; NSC: n = 6; mean age 9.32 ± 2.67 years ...

An Iterative Bidirectional Gradient Boosting Algorithm for CVR Baseline Estimation

2023 IEEE Power & Energy Society General Meeting (PESGM), 2023
This paper presents a novel Iterative Bidirectional Gradient Boosting Model (IBi-GBM) for estimating the baseline of Conservation Voltage Reduction (CVR) programs. In contrast to many existing methods, we treat CVR baseline estimation as a missing data retrieval problem. The approach involves dividing the load and its corresponding temperature profiles
