Anomalies on Orbifolds [PDF]

open access: yes, 2001
We discuss the form of the chiral anomaly on an S1/Z2 orbifold with chiral boundary conditions. We find that the 4-divergence of the higher-dimensional current evaluated at a given point in the extra dimension is proportional to the probability of ...

Ebstein's Anomaly [PDF]

open access: yesCirculation, 1957
Four cases of Ebstein's anomaly are described, revealing that the clinical features permit diagnosis in the majority of instances and that cardiac catheterization affords precise confirmation of the diagnosis. The occurrence of this anomaly in acyanotic adults is pointed out, and the similarity to acquired valvular rheumatic heart disease is stressed.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Double appendix and anorectal malformation: A case report

open access: yesJournal of Pediatric Surgery Case Reports
Background: Double appendix, also known as vermiform appendix duplex, is a rare congenital anomaly. It is estimated to occur in 1 in 25,000 people with fewer than hundred cases reported worldwide.

Conformal Anomalies in Noncommutative Gauge Theories

open access: yes, 2002
We calculate conformal anomalies in noncommutative gauge theories by using the path integral method (Fujikawa's method). Along with the axial anomalies and chiral gauge anomalies, conformal anomalies take the form of the straightforward Moyal deformation

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Swenson-like pull-through for treatment of the rare association between Hirschsprung’s disease and anorectal malformation

open access: yesBMC Pediatrics
Background Anorectal malformations and Hirschsprung’s disease are congenital conditions impacting the digestive system, with a particularly uncommon co-occurrence, estimated at 2–3% of all ARM cases.

Comparison of oocyte vitrification using a semi-automated or a manual closed system in human siblings: survival and transcriptomic analyses

open access: yesJournal of Ovarian Research, 2022
Background Indications of oocyte vitrification increased substantially over the last decades for clinical and ethical reasons. A semi-automated vitrification system was recently developed making each act of vitrification reproducible.

Spectral Action from Anomalies [PDF]

open access: yes, 2010
Starting from a theory of fermions moving in a fixed gauge and gravitational background we implement the scale invariance of the theory. Upon quantization the theory is anomalous but the anomaly can be cancelled by the addition of another term to the ...

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)
