Neural Dysfunction Underlying Working Memory Processing at Different Stages of the Illness Course in Schizophrenia:A Comparative Meta-analysis [PDF]

arXiv, 2023
Schizophrenia (SCZ), as a chronic and persistent disorder, exhibits working memory deficits across various stages of the disorder, yet the neural mechanisms underlying these deficits remain elusive with inconsistent neuroimaging findings. We aimed to compare the brain functional changes of working memory in patients at different stages: clinical high ...

Superior vena caval syndrome caused by the tumor of the left hilum in a patient with unilateral persistent left superior vena cava diagnosed with multislice spiral computed tomography : a case report [PDF]

, 2007
Background: Unilateral persistent left superior vena cava (PLSVC) is an infrequent finding with incidence of 18-20% among the individuals with PLSVC. The persistence of the left-sided superior vena cava is an effect of disturbances in development of the ...

Persistent left superior vena cava in cardiac congenital surgery. [PDF]

, 2014
Persistent left superior vena cava (LSVC) is a relatively frequent finding in congenital cardiac malformation. The scope of the study was to analyze the timing of diagnosis of persistent LSVC, the timing of diagnosis of associated anomalies of the ...

Assessment of Double Outlet Left Ventricle in Pediatrics Using Transthoracic Echocardiography and Computed Tomographic Angiography

Pediatric Discovery, EarlyView.
The clinical manifestation of DOLV was atypical. TTE has a relatively high diagnostic accuracy for DOLV in pediatric, which is very valuable for its early detection. ABSTRACT Double outlet left ventricle (DOLV) is a rare congenital cardiac anomaly in which both great arteries originate entirely or predominantly from the morphologic left ventricle.

Conductor extrusion in a persistent left superior vena cava [PDF]

Europace, 2011
A 55-year-old man with a persistent left and an absent right superior vena cava (SVC) underwent an atraumatic left-sided implantation via a large left cephalic vein of a dual-chamber implantable-cardioverter defibrillator (ICD) with a 7.8F Biotronik 75/18 (Linox SD) active fixation ICD lead in 2008. In 2011, during coronary angiography prior to planned

Manipulation of Wnt/β‐Catenin Signaling by Synthetic Frizzled Agonist and LRP Antagonist in Organoid Cultures and In Vivo

Small Methods, EarlyView.
Harnessing synthetic key receptor modulators, this study presents a breakthrough in Wnt/β‐catenin regulation. The FZD agonist RRP‐pbFn bypasses LRP5/6 to drive organoid expansion and tissue regeneration, while the LRP antagonist RRP‐Dkk1c eradicates tumors. These tools enable precise pathway control, advancing regenerative and cancer therapies.

A multilayer interstitial fluid flow along vascular adventitia [PDF]

arXiv, 2020
Objective: Interstitial fluid flow through vascular adventitia has been disclosed recently. However, its kinetic pattern was unclear. Methods and Results: We used histological and topographical identifications to observe ISF flow along venous vessels in rabbits.

Persistent Left Cranial Vena Cava in a Dog [PDF]

, 2011
Background: Persistent left cranial vena cava with absent right cranial vena cava is a rare anomaly. Congenitally persistent left cranial vena cava is the most common variant of the systemic venous return to the heart, embryologically resulting from ...

$μ$SR study of spin freezing and persistent spin dynamics in NaCaNi$_2$F$_7$ [PDF]

, 2018
A new pyrochlore compound, NaCaNi$_2$F$_7$, was recently synthesized and has a single magnetic site with spin-1 Ni$^{2+}$. We present zero field (ZF) and longitudinal field (LF) muon spin rotation ($\mu$SR) measurements on this pyrochlore. Density functional theory (DFT) calculations show that the most likely muon site is located between two fluorine ...
