Primary presacral neuroendocrine tumor associated with imperforate anus

open access: yesWorld Journal of Surgical Oncology, 2007
Background Presacral masses are unusual growths that have a limited differential diagnosis, typically not including neuroendocrine tumors (NETs). Classically, NETs are well-differentiated gastroenteropancreatic tumors of probable benign behavior.

Application of additional three-dimensional materials for education in pediatric anatomy

open access: yesScientific Reports, 2023
We conducted this study to investigate the effects of additional education using 3D visualization (3DV) and 3D printing (3DP) after applying 2D images for anatomical education in normal pediatric structures and congenital anomalies. For the production of

Short‐ and Long‐Term Outcomes of Prenatally Identified Congenital Aqueductal Stenosis by Fetal MRI

open access: yesPrenatal Diagnosis, Volume 44, Issue 13, Page 1574-1584, December 2024.
ABSTRACT Objective Providing accurate prenatal prognostication for expectant parents is challenging due to limited literature on factors impacting outcomes in children with congenital aqueductal stenosis (CAS). This study stratified CAS patients into isolated or complex categories (presence of additional intra‐ or extra‐cranial anomalies or genetic ...

Converting the ANU 2.3 telescope to fully automated operation [PDF]

open access: yesPublications of the Astronomical Society of Australia, Volume 41, article id. e057 (September 2024)
The operation of the ANU 2.3m telescope transitioned from classically scheduled remote observing to fully autonomous queue scheduled observing in March 2023. The instrument currently supported is WiFeS, a visible-light low-resolution image-slicing integral field spectrograph with a 25''x 38'' field of view (offering precision spectrophotometry free ...

Genetics of anomalies of the kidney and urinary tract with congenital heart disease: A review

open access: yesClinical Genetics, Volume 106, Issue 6, Page 667-678, December 2024.
Anomalies of the kidney and heart are the most commonly recognized congenital defects and constitute a major cause of morbidity in children. For example, STRING protein‐protein interaction network for the hepatocyte nuclear factor 1‐beta (HNF1B) gene with first‐tier functional interactions involving detection of glucose and exocrine pancreas ...

Prenatal diagnosis of a 15q24.1 microdeletion in a fetus with cerebral and urogenital abnormalities

open access: yesClinical Genetics, Volume 106, Issue 5, Page 537-544, November 2024.
15q24.1 microdeletion syndrome is a rare condition, rarely diagnosed before birth. We give new insights into prenatal malformations and candidate genes involved in embryogenesis. Such malformations on ultrasound scan, may lead to prenatal genetic testing. Abstract 15q24.1 microdeletion syndrome is a recently described condition often resulting from non‐

Congenital Anomalies of the Gastrointestinal Tract in Conjunction of Congenital Heart Diseases in Infants With Trisomy 21

open access: yesBirth Defects Research, Volume 116, Issue 10, October 2024.
ABSTRACT Background Infants with Trisomy 21 are known to have increased incidence congenital anomalies including congenital heart diseases (CHD) and congenital gastrointestinal anomalies. It is not known if there are patterns of coexistence. Objectives To examine the coexistence of CHD with various gastrointestinal anomalies in infants with Trisomy 21.

Decoherence and the Quantum Zeno Effect [PDF]

open access: yesarXiv, 1995
The measurements in the optical test of quantum Zeno effect [Itano et al. Phys. Rev. A\underbar{41} (1990) 2295) are analyzed using the environment-induced decoherence theory, where the spontaneous emission lifetime of the relevant level emerges as the 'decoherence time'. The implication of this finite decoherence time in setting a fundamental limit on
