Progress report on multiple endocrine neoplasia type 1.

Fam Cancer

January 2025

Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

Large Language Models (LLMs) have shown success in predicting neural signals associated with narrative processing, but their approach to integrating context over large timescales differs fundamentally from that of the human brain. In this study, we show how the brain, unlike LLMs that process large text windows in parallel, integrates short-term and long-term contextual information through an incremental mechanism. Using fMRI data from 219 participants listening to spoken narratives, we first demonstrate that LLMs predict brain activity effectively only when using short contextual windows of up to a few dozen words.

International Symposium on Ruminant Physiology: The involvement of the endocannabinoid system in metabolic and inflammatory responses in dairy cows during negative energy balance.

J Dairy Sci

January 2025

Department of Ruminant Science, Institute of Animal Sciences, ARO Volcani Institute, Israel; Department of Animal Science, The Robert H. Smith Faculty of Agriculture, Food and Environment, The Hebrew University of Jerusalem, Rehovot, Israel.

The endocannabinoid system (ECS) is involved in the regulation of energy metabolism, immune function and reproduction in mammals. The ECS is consisted of the endocannabinoid (eCB) ligands, enzymes, and cannabinoid receptors. In mammals, the cannabinoid-1 receptor (CB1/CNR1) is expressed in the central nervous system and in peripheral tissues; and its activation increases anabolic processes.

Omega-3 fatty acids supplementation from late pregnancy to early lactation attenuates the endocannabinoid system and immune proteome in preovulatory follicles and endometrium of Holstein dairy cows.

J Dairy Sci

January 2025

Department of Ruminant Science, Institute of Animal Sciences, Agricultural Research Organization, Volcani Institute, Rishon LeZion, Israel. Electronic address:

Activation of the endocannabinoid system (ECS) elicits negative effects on the reproductive system in mammals. Omega-3 (n-3) fatty acid (FA) supplementation lowers ECS activation and has anti-inflammatory effects. Thus, we hypothesized that supplementing cows with n-3 FA will downregulate components of the ECS and immune system in preovulatory follicles and in the endometrium.

Neural Rewiring of Resilience: The Effects of Combat Deployment on Functional Network Architecture.

Biol Psychiatry Cogn Neurosci Neuroimaging

January 2025

School of Psychological Sciences, Sagol School of Neuroscience, Tel-Aviv University.

Background: Although combat-deployed soldiers are at a high risk for developing trauma-related psychopathology, most will remain resilient for the duration and aftermath of their deployment tour. The neural basis of this type of resilience is largely unknown, and few longitudinal studies exist on neural adaptation to combat in resilient individuals for whom a pre-exposure measurement was collected. Here, we delineate changes in the architecture of functional brain networks from pre- to post-combat in psychopathology-free, resilient participants.

Pediatric intensive care patients are particularly susceptible to severe bacterial infections because of ineffective neutrophil responses. The reasons why neutrophils of newborns are less responsive than those of adults are not clear. Because adenosine triphosphate (ATP) and adenosine (ADO) tightly regulate neutrophils, we studied whether the ATP and ADO levels in the blood of newborn mice could impair the function of their neutrophils.
