Multiple Idiopathic Cervical Root Resorption: A Challenge for a Transdisciplinary Medical-Dental Team [PDF]

arXiv, 2021
While tooth root resorption is a normal physiological process required for resorption and exfoliation of primary teeth, root resorption of adult teeth is largely pathological. This perspective focuses on multiple idiopathic cervical root resorption (MICRR), an aggressive form of external root resorption that occurs near the cemento-enamel junction (CEJ)

A Thrombocytopenic Thrombotic Purpura in a Patient With a Metastatic HER2+ Breast Cancer: Description of a Case Report

Clinical Case Reports, Volume 13, Issue 4, April 2025.
ABSTRACT Paraneoplastic (p) TTP is a rare syndrome characterized by an immune‐induced, generalized microangiopathy associated with solid or hematological tumors. This case, reporting a patient with a metastatic HER2+ breast cancer and a pTTP, highlights the rarity of this entity, its difficult and challenging diagnosis, and the complexity of its ...

Prevalence and Risk Factors Associated With Cesarean Section in Syria: A Cross‐Sectional Study of the Two Largest Health Centers

Health Science Reports, Volume 8, Issue 4, April 2025.
ABSTRACT Background and Aims A cesarean section (CS) is a surgical procedure used during pregnancy and childbirth to ensure maternal and fetal well‐being. Global CS rates are increasing, with different studies demonstrating this trend. The purpose of this study, is to look into the prevalence of CS and its contributing factors in Syrian hospitals ...

A comment on "A fast L_p spike alignment metric" by A. J. Dubbs, B. A. Seiler and M. O. Magnasco [arXiv:0907.3137] [PDF]

arXiv, 2009
Measuring the transmitted information in metric-based clustering has become something of a standard test for the performance of a spike train metric. In this comment, the recently proposed L_p Victor-Purpura metric is used to cluster spiking responses to zebra finch songs, recorded from field L of anesthetized zebra finch.

Development of Machine learning algorithms to identify the Cobb angle in adolescents with idiopathic scoliosis based on lumbosacral joint efforts during gait (Case study) [PDF]

arXiv, 2023
Objectives: To quantify the magnitude of spinal deformity in adolescent idiopathic scoliosis (AIS), the Cobb angle is measured on X-ray images of the spine. Continuous exposure to X-ray radiation to follow-up the progression of scoliosis may lead to negative side effects on patients. Furthermore, manual measurement of the Cobb angle could lead to up to

Origins of T‐cell‐mediated autoimmunity in acquired aplastic anaemia

British Journal of Haematology, Volume 206, Issue 4, Page 1035-1053, April 2025.
Acquired aplastic anaemia (AA) is an autoimmune bone marrow failure disease caused by a cytotoxic T‐cell–mediated attack on haematopoietic stem and progenitor cells (HSPCs). Despite significant progress in understanding T‐cell repertoire alterations in AA, the identification of specific pathogenic T cells remains elusive.

Localizing the Origin of Idiopathic Ventricular Arrhythmia from ECG Using an Attention-Based Recurrent Convolutional Neural Network [PDF]

arXiv, 2023
Idiopathic ventricular arrhythmia (IVAs) is extra abnormal heartbeats disturbing the regular heart rhythm that can become fatal if left untreated. Cardiac catheter ablation is the standard approach to treat IVAs, however, a crucial prerequisite for the ablation is the localization of IVAs' origin.

A New Diagnostic Approach for Myelodysplastic Neoplasms Using a Combination of Scores Based on Flow Cytometry and Automated Hematology Sysmex XN Analyzers

International Journal of Laboratory Hematology, Volume 47, Issue 2, Page 236-245, April 2025.
ABSTRACT Introduction The first‐step in diagnosis of myelodysplastic neoplasms (MDS) is essentially based on bone marrow cytomorphology. However, cytomorphology of MDS is often a difficult exercise, subject to inter‐operator variability. Our study aims to evaluate whether the combination of two dysplasia scores, the extended Ogata score and the MDS‐CBC

Statistically adaptive learning for a general class of cost functions (SA L-BFGS) [PDF]

arXiv, 2012
We present a system that enables rapid model experimentation for tera-scale machine learning with trillions of non-zero features, billions of training examples, and millions of parameters. Our contribution to the literature is a new method (SA L-BFGS) for changing batch L-BFGS to perform in near real-time by using statistical tools to balance the ...
