The Constrained Disorder Principle Overcomes the Challenges of Methods for Assessing Uncertainty in Biological Systems.

J Pers Med

December 2024

Department of Medicine, Hadassah Medical Center, Faculty of Medicine, Hebrew University, Jerusalem 9112102, Israel.

Different disciplines are developing various methods for determining and dealing with uncertainties in complex systems. The constrained disorder principle (CDP) accounts for the randomness, variability, and uncertainty that characterize biological systems and are essential for their proper function. Per the CDP, intrinsic unpredictability is mandatory for the dynamicity of biological systems under continuously changing internal and external perturbations.

Buccal cortical bone dimensions are crucial in dental radiology, as they impact orthodontic treatment outcomes. Changes in alveolar bone dimensions can result in malocclusion and require interdisciplinary approaches for correction. The accurate quantification of buccal bone dimensions is crucial for appropriate treatment planning and avoiding medico-legal issues.

Diagnostic clues in herpes encephalitis following radiation therapy.

J Neurol Sci

January 2025

The Gaffin Center for Neuro-Oncology, Sharett Institute of Oncology, Hadassah Medical Center, and Faculty of Medicine, The Hebrew University of Jerusalem, Israel. Electronic address:

Introduction: Herpes encephalitis is known to affect patients undergoing brain radiotherapy, but early diagnosis and treatment, the foremost determinants of disease outcome, remain challenging in this patient population. This can be due to attribution of symptoms to the brain tumor and radiation side effects, as well as patients' atypical clinical presentation. Here we sought to highlight pearls and pitfalls in the clinical course and diagnostic workup which may facilitate timely diagnosis and improve disease outcome.

Alternative splicing (AS) is a mechanism that generates translational diversity within a genome. Equally important is the dynamic adaptability of the splicing machinery, which can give preference to one isoform over others encoded by a single gene. These isoform preferences change in response to the cell's state and function.

Introduction: Cardiac computerized tomographic angiography (CCTA) is perceived as a non-invasive tool for assessment of coronary vessel anatomy. Feature tracking echocardiography has recently emerged as a tool for assessment of regional and global left ventricular function. We aimed to explore the applicability of echocardiographic strain on CCTA cine clips and assess whether global and regional strain parameters are associated with the extent of coronary stenosis.

Sleeve gastrectomy reveals the plasticity of the human gastric epithelium.

Nat Commun

January 2025

Department of Developmental Biology and Cancer Research, The Institute for Medical Research Israel Canada, The Faculty of Medicine, The Hebrew University of Jerusalem, Jerusalem, Israel.

Gastrin is secreted following a rise in gastric pH, leading to gastric acid secretion. Sleeve gastrectomy (SG), a bariatric surgery where 80% of the gastric corpus is excised, presents a challenge for gastric pH homeostasis. Using histology, and single-cell RNA sequencing of the gastric epithelium in 12 women, we observed that SG is associated with an increase in a sub-population of acid-secreting parietal cells that overexpress respiratory enzymes and an increase in histamine-secreting enterochromaffin-like cells (ECLs).

The skin, our first line of defense against external threats, combines a physical barrier and a rich microbial community. Disruptions of this community, for example, due to infectious injury, have been linked to a decrease in bacteria diversity and to mild to severe pathological conditions. Although some progress has been made in the field, possibilities/procedures for restoring the skin microbiome are still far from ideal.

Background: Although most inflammatory bowel disease (IBD) medications are considered safe during pregnancy, their impact on microRNAs (miRNAs) in breast milk is largely unknown. MiRNAs in milk, carried by milk-derived extracellular vesicles (MDEs), are transmitted to the newborn's gut to regulate genes. Aberrant miRNA expression profiles have been found in IBD within tissue, blood, and feces, but data on mother's milk are scarce.

Spec Care Dentist

January 2025

Department of Periodontology, Faculty of Dental Medicine, Hadassah Medical Center, Hebrew University of Jerusalem, Jerusalem, Israel.

Aims: To assess and compare the effectiveness of pharmacological and cognitive-behavioral modalities-behavioral methods (BM), nitrous oxide inhalation sedation (NOIS), and premedication with Diazepam-for alleviating anxiety during dental treatment, using completed treatment sessions and adverse outcomes as indicators.

Methods And Results: For 239 patients (515 dental records), 18-53 y/o, who underwent dental treatments under anxiety reduction measures, sessions under NOIS were categorized as "nitrous group" (456 sessions) versus premedication with Diazepam or behavioral strategies (control, 59 sessions).
