Background: Correct identification of the epidural space requires extensive training for technical proficiency. This study explores a novel bimanual haptic simulator designed for the precise insertion of an epidural needle based on loss-of-resistance (LOR) detection, providing realistic dual-hand force feedback.

Methods: The simulator, equipped with two haptic devices connected to a Tuohy needle and an LOR syringe, was designed to simulate the tissues' resistive forces felt by the user during the procedure, offer anatomical variability and record detailed performance metrics for personalized feedback.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Mitochondrial DNA (mtDNA) is highly polymorphic, and host mtDNA variation has been associated with altered cancer severity. To determine the basis of this mtDNA-cancer association, we analyzed conplastic mice with the C57BL/6J (B6) nucleus but two naturally occurring mtDNA lineages, and , where mitochondria generate more oxidative phosphorylation (OXPHOS)-derived reactive oxygen species (mROS). In a cardiac transplant model, Foxp3+ T regulatory (Treg) cells supported long-term allograft survival, whereas Treg cells failed to suppress host T effector (Teff) cells, leading to acute rejection.

Introduction: AIM: The aim of the study is to determine the optimal timing for surgery in patients with small bowel duplications.

Methods: A retrospective cohort study, including all patients younger than 18 years who were diagnosed with small bowel duplications from 2013 until 2024 in a single tertiary medical center, was performed. Patients' demographics, duplication size and location, pathological results, and clinical outcomes were collected.

Background: The prevalence of mental health disorders among children and adolescents presents a significant public health challenge. Children exposed to armed conflicts are at a particularly high risk of developing mental health problems, necessitating prompt and robust intervention. The acute need for early intervention in these situations is well recognized, as timely support can mitigate long-term negative outcomes.

Purpose: After primary systemic therapy (PST), agreement on the extent of locoregional therapy is lacking in breast cancer patients who convert from a node-positive to a node-negative status. The aim of this survey was to investigate radiation therapy approaches after PST according to different axillary surgical strategies and disease responses.

Materials And Methods: The European Breast Cancer Research Association of Surgical Trialists developed a web-based survey containing 39 questions on locoregional management based on clinical scenarios in initially node positive breast cancer patients undergoing PST.

Propagation of membrane tension mediates mechanical signal transduction along surfaces of live cells and sets the time scale of mechanical equilibration of cell membranes. Recent studies in several cell types and under different conditions revealed a strikingly wide variation range of the tension propagation speeds including extremely low ones. The latter suggests a possibility of long-living inhomogeneities of membrane tension crucially affecting mechano-sensitive membrane processes.

Prediction and observation of topological modes in fractal nonlinear optics.

Light Sci Appl

January 2025

Department of Physical Electronics, School of Electrical Engineering, Faculty of Engineering, and Center for Light-Matter Interaction, Tel Aviv University, Tel Aviv, Israel.

This item from the News and Views (N&V) category aims to provide a summary of theoretical and experimental results recently published in ref. , which demonstrates the creation of corner modes in nonlinear optical waveguides of the higher-order topological insulator (HOTI) type. Actually, these are second-order HOTIs, in which the transverse dimension of the topologically protected edge modes is smaller than the bulk dimension (it is 2, in the case of optical waveguide) by 2, implying zero dimension of the protected modes, which are actually realized as corner or defect ones.

In soil polluted with benzene, toluene, ethylbenzene, and xylenes (BTEX), oxygen is rapidly depleted by aerobic respiration, creating a redox gradient across the plume. Under anaerobic conditions, BTEX biodegradation is then coupled with fermentation and methanogenesis. This study aimed to characterize this multi-step process, focusing on the interactions and functional roles of key microbial groups involved.

Approach to the Patient with Thyroid Cancer: Selection and Management of Candidates for Lobectomy.

J Clin Endocrinol Metab

January 2025

Department of Otolaryngology-Head and Neck Surgery, Beilinson Hospital, Rabin Medical Center.

Thyroid lobectomy has gained increasing popularity over the past decade as a treatment for differentiated thyroid cancer (DTC), largely due to a rise in the diagnosis of low-risk cancers and evidence showing no benefit from radioiodine in low-risk disease. Multiple studies have confirmed lobectomy as an effective and safe option. Its advantages over total thyroidectomy include lower complication rates and a reduced need for lifelong levothyroxine (LT4) therapy.

Background: Labour epidural analgesia reportedly fails in up to 10 to 25% of cases. A joint taskforce of European Society of Anaesthesiology and Intensive Care (ESAIC) experts was created to develop this focused guideline on the management of failing epidural analgesia in a previously well functioning epidural catheter.

Design: Six clinical questions were defined using a PICO (Population/Intervention/Comparison/Outcome) strategy to conduct a systematic literature search.

Myths and fitness interdependence: Beyond coalitional longevity.

Behav Brain Sci

January 2025

The Buchmann Faculty of Law, Tel Aviv University, Ramat Aviv,

This comment seeks to extend the authors' argument by considering how perceived fitness interdependence is generated in different settings. Based primarily on research from political science, it argues that strategic agents may seek to design myths that emphasize not only the longevity of their coalitions, but also internal features such as material and status equality and institutional impartiality.

Article Synopsis
  • T-lineage acute lymphoblastic leukemia (ALL) presents as an aggressive cancer with diverse subtypes, making traditional classification difficult.
  • A multiomics analysis of bone marrow samples revealed a specific subset of T-lineage ALL with active inflammatory and stem gene programs, showing unique biological and treatment response characteristics.
  • A computational inflammatory gene signature scoring system was developed to better classify patients, identifying a high-risk subtype that could guide targeted therapies for more effective treatment approaches.

Coronary artery disease (CAD) affects over 200 million individuals globally, accounting for approximately 9 million deaths annually. Patients living with diabetes mellitus exhibit an up to fourfold increased risk of developing CAD compared to individuals without diabetes. Furthermore, CAD is responsible for 40 to 80 percent of the observed mortality rates among patients with type 2 diabetes.
