Bilateral Absence of the Superior Vena Cava

open access: yesCase Reports in Cardiology, 2012
Bilateral absence of the superior vena cava (SVC) is a very rarely detected, mainly asymptomatic congenital vascular anomaly. Though usually innocent, this anomaly may complicate cardiothoracic surgery and certain procedures like central venous catheter ...

Duplication of the Superior Vena Cava in an Elderly Patient on Hemodialysis

open access: yesInternational Journal of Gerontology, 2017
Summary: The prevalence of elderly patients who are dependent on hemodialysis (HD) has increased worldwide. We report the case of an 81-year-old man with end-stage renal disease who displayed a duplication of the superior vena cava (SVC) with bilateral ...

High Sensitivity Cardiac Troponin I Detection via MP‐Locked Aptamer and Multimeric DNAzyme‐Coupled Hyperbranched Hybridization Chain Reaction

open access: yesSmall, EarlyView.
We report a magnetic particle anchored locked aptamer platform integrated with hyperbranched HCR and DNAzyme amplification for enzyme‐free, ultrasensitive detection of cardiac troponin I. The assay achieves a 0.25 ng/L detection limit within 25 minutes and enables cross‐species MI detection, with machine learning classification reaching 90% accuracy ...

Ultrasensitive MicroRNA Detection Combining Reduced Graphene Oxide Electrolyte‐Gated Transistors and Machine Learning

open access: yesSmall, EarlyView.
We developed an ultrasensitive and highly selective biosensor by integrating bio‐functionalized reduced graphene oxide (rGO) electrolyte‐gated transistors (EGTs) and machine learning (ML) to detect miRNAs (miR‐34a, miR‐34b, and miR‐34c) associated with cancer and neurological disorders.

Temporal Characteristics and Management of Prolonged Sinus Pause Following Atrial Fibrillation Termination After Catheter Ablation-A Preliminary Study. [PDF]

open access: yesAnn Noninvasive Electrocardiol
Twelve of the 1330 patients who underwent AF catheter ablation showed PSP ≥ 3 s after AF termination post ablation. The temporal characteristics of PSP were described. Nine of the 12 patients had no need for permanent pacing. We concluded that a ‘watch‐and‐wait’ strategy could be adopted in these patients.

A Bird's Eye View of English Grammar: Connecting the Dots in Two Dimensions

open access: yesTESOL Quarterly, EarlyView.
Abstract Over the past few decades, discussions on grammar instruction have primarily focused on teaching methodologies, such as whether grammar should be taught explicitly or implicitly, and whether the focus should be on form or forms. This paper, however, shifts the focus to grammar itself, aiming to provide a “shape” for pedagogical grammar.

Venture Capital Practices in Saudi Arabia: The Views of Investors

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT This study examines how venture capital (VC) investors in Saudi Arabia evaluate, negotiate, and support entrepreneurial ventures in a rapidly developing yet institutionally young setting. Drawing on 21 semi‐structured interviews with 24 investors, it offers rare insight into VC practices in the Middle East.

Superior vena cava syndrome in hemodialysis patient

open access: yesSaudi Journal of Kidney Diseases and Transplantation, 2011
Obstruction of blood flow in the superior vena cava (SVC) results in symptoms and signs of SVC syndrome. SVC obstruction can be caused either by invasion or external compression of the SVC by contagious pathologic processes involving the right lung ...

Permutation Models and SVC

open access: yesNotre Dame Journal of Formal Logic, 2007
Let M be a model of ZFAC (ZFC modified to allow a set of atoms), and let N be an inner model with the same set of atoms and the same pure sets (sets with no atoms in their transitive closure) as M. We show that N is a permutation submodel of M if and only if N satisfies the principle SVC (Small Violations of Choice), a weak form of the axiom of choice ...

Improving drug identification in overdose death surveillance by using clinical natural language processing models

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract The rising rate of drug‐related deaths in the United States, largely driven by fentanyl, requires timely and accurate surveillance. However, critical overdose data are often buried in free‐text coroner reports, leading to delays and information loss when coded into ICD (International Classification of Disease)‐10 classifications.
