Identification of global transcriptional variations in human peripheral blood mononuclear cells two months postheat injury helps categorization heat-tolerant or heat-intolerant phenotypes.

Thermal intolerance may limit activity in hostile environments. After heat illness, two physiologically distinct phenotypes evolve: heat tolerant (HT) and heat intolerant (HI). The recognition that heat illness alters gene expression justified revisiting the established physiological concept of HI.

Simple Continuous Glucose Monitoring in Freely Moving Mice.

Mice are a common model organism used to study metabolic diseases such as diabetes mellitus. Glucose levels are typically measured by tail-bleeding, which requires handling the mice, causes stress, and does not provide data on freely behaving mice during the dark cycle. State-of-the-art continuous glucose measurement in mice requires inserting a probe into the aortic arch of the mouse, as well as a specialized telemetry system.

The impact of minor trauma during pregnancy on maternal and neonatal outcomes: A tertiary centre experience.

Introduction: The aim of this study was to evaluate the impact of minor trauma during pregnancy on maternal and fetal outcomes in patients managed in a tertiary setting.

Materials And Methods: A retrospective single centre case-controlled study was performed between 2005 and 2017 in a university affiliated tertiary obstetric and trauma centre. All pregnant women of 13-36 weeks gestation that presented to the department of emergency medicine with an Injury Severity Score of <9 were identified.

Occurrence of Herpes Viruses in Morphologically Normal Corneas.

Purpose: The purpose of this study was to detect the occurrence of herpes simplex virus (HSV) types 1 and 2 and varicella zoster virus (VZV) DNA in transplanted corneas using polymerase chain reaction (PCR) and to determine the relationship between latent HSV and VZV and herpetic eye disease in recipients.

Methods: This was a retrospective, interventional case series. Samples from 88 donor corneoscleral buttons (CSBs) were collected from the conjunctiva, iris, and endothelium and tested for HSV-1, HSV-2, and VZV DNA using PCR.

Epidural Analgesia for Labour: Comparing the Effects of Continuous Epidural Infusion (CEI) and Programmed Intermittent Epidural Bolus (PIEB) on Obstetric Outcomes.

Objective: In the last few years there is a trend of transiting from the continuous epidural infusion (CEI) method for epidural analgesia to a new method - programmed intermittent epidural analgesia (PIEB). This change improves the quality of epidural analgesia, thanks to an increased spread of the anaesthetic in the epidural space and higher maternal satisfaction. Nevertheless, we must make sure that such change of method does not lead to worse obstetric and neonatal outcomes.

Rules for body fat interventions based on an operating point mechanism.

Interventions to reduce fat are important for human health. However, they can have opposing effects such as exercise that decreases fat but increases food intake, or coherent effects such as leptin resistance which raises both. Furthermore, some interventions show an overshoot in food intake, such as recovery from a diet, whereas others do not.

Topical phage therapy in a mouse model of Cutibacterium acnes-induced acne-like lesions.

Acne vulgaris is a common neutrophil-driven inflammatory skin disorder in which Cutibacterium acnes (C. acnes) is known to play a key role. For decades, antibiotics have been widely employed to treat acne vulgaris, inevitably resulting in increased bacterial antibiotic resistance.

Intramuscular mRNA BNT162b2 vaccine against SARS-CoV-2 induces neutralizing salivary IgA.

Intramuscularly administered vaccines stimulate robust serum neutralizing antibodies, yet they are often less competent in eliciting sustainable "sterilizing immunity" at the mucosal level. Our study uncovers a strong temporary neutralizing mucosal component of immunity, emanating from intramuscular administration of an mRNA vaccine. We show that saliva of BNT162b2 vaccinees contains temporary IgA targeting the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus-2 spike protein and demonstrate that these IgAs mediate neutralization.

The Impact of Dominant Ventricular Morphology on the Early Postoperative Course After the Glenn Procedure.

The dominant ventricular morphology affects both the early and late outcomes of the Fontan procedure, but its impact on the patients' status immediately following the Glenn procedure is unknown. This study aims to evaluate the effect of the infants' dominant ventricular morphology on the immediate course after undergoing the Glenn procedure. This single-center, retrospective study included all patients who underwent the Glenn procedure between October 2003 and May 2016.

HIV co-opts a cellular antiviral mechanism, activation of stress kinase PKR by its RNA, to enable splicing of rev/tat mRNA.

Background: Activation of RNA-dependent stress kinase PKR, especially by viral double-stranded RNA, induces eukaryotic initiation factor 2 α-chain (eIF2α) phosphorylation, attenuating thereby translation. We report that this RNA-mediated negative control mechanism, considered a cornerstone of the cell's antiviral response, positively regulates splicing of a viral mRNA.

Results: Excision of the large human immunodeficiency virus (HIV) rev/tat intron depends strictly on activation of PKR by the viral RNA and on eIF2α phosphorylation.

Comparison of biometry measurements and intraocular lens power prediction between 2 SS-OCT-based biometers.

Purpose: To evaluate the agreement in biometry measurements and intraocular lens (IOL) power prediction between the Eyestar 900 and the IOLMaster 700.

Setting: Institutional.

Design: Retrospective comparative study.

Changes and trends in medication-assisted treatment in Israel.

Background: As opioid prescription in Israel is increasing, there is a growing need for monitoring opioid use disorder and providing opioid agonist therapy. Our goal is to describe, sub-analyze, and identify obstacles in the treatment of opioid misuse in the Israeli medication assisted treatment centers.

Methods: Data on methadone, buprenorphine, and buprenorphine combined with naloxone for the indication of opioid addiction treatment for the period 2013-2020 were obtained from pharmaceutical companies that distribute them in Israel.

Targeting splicing factors for cancer therapy.

Alternative splicing (AS) of mRNAs is an essential regulatory mechanism in eukaryotic gene expression. AS misregulation, caused by either dysregulation or mutation of splicing factors, has been shown to be involved in cancer development and progression, making splicing factors suitable targets for cancer therapy. In recent years, various types of pharmacological modulators, such as small molecules and oligonucleotides, targeting distinct components of the splicing machinery, have been under development to treat multiple disorders.

The Genetic Etiology of Parkinson's Disease Does Not Robustly Affect Subthalamic Physiology.

Background: It is unknown whether Parkinson's disease (PD) genetic heterogeneity, leading to phenotypic and pathological variability, is also associated with variability in the unique PD electrophysiological signature. Such variability might have practical implications for adaptive deep brain stimulation (DBS).

Objective: The aim of our work was to study the electrophysiological activity in the subthalamic nucleus (STN) of patients with PD with pathogenic variants in different disease-causing genes.

Human RNase P: overview of a ribonuclease of interrelated molecular networks and gene-targeting systems.

The seminal discovery of ribonuclease P (RNase P) and its catalytic RNA by Sidney Altman has not only revolutionized our understanding of life, but also opened new fields for scientific exploration and investigation. This review focuses on human RNase P and its use as a gene-targeting tool, two topics initiated in Altman's laboratory. We outline early works on human RNase P as a tRNA processing enzyme and comment on its expanding nonconventional functions in molecular networks of transcription, chromatin remodeling, homology-directed repair, and innate immunity.

Anti-PEG antibodies before and after a first dose of Comirnaty® (mRNA-LNP-based SARS-CoV-2 vaccine).

The early and massive vaccination campaign in Israel with the mRNA-LNP Comirnaty® (Pfizer-BioNTech) vaccine against the SARS-CoV-2 virus made available large amounts of data regarding the efficacy and safety of this vaccine. Adverse reactions to mRNA-based SARS-CoV-2 vaccines are rare events, but due to large mediatic coverage they became feared and acted as a potential source of delay for the vaccination of the Israeli population. The experience with the reactogenicity of the polyethylene glycol (PEG) moiety of PEGylated liposomes, PEGylated proteins and other PEGylated drugs raised the fear that similar adverse effects can be associated with the PEG lipid which is an essential component of currently used mRNA-LNP vaccines against COVID-19.

Comparison between School-Age Children with and without Obesity in Nutritional and Inflammation Biomarkers.

Childhood obesity is a major health problem. We examined differences between children with obesity and normal weight in nutritional and inflammation biomarkers. A cross-sectional study was conducted among healthy children aged 10-12 years from Arab villages in Israel.

A universal cell-free DNA approach for response prediction to preoperative chemoradiation in rectal cancer.

The standard treatment approach for stage II/III rectal cancer is neoadjuvant chemoradiation therapy (nCRT) followed by surgery. In recent years, new treatment approaches have led to higher rates of complete tumor eradication combined with organ-preservation strategies. However, better tools are still needed to personalize therapy for the individual patient.

Glycemic control releases regenerative potential of pancreatic beta cells blocked by severe hyperglycemia.

Diabetogenic ablation of beta cells in mice triggers a regenerative response whereby surviving beta cells proliferate and euglycemia is regained. Here, we identify and characterize heterogeneity in response to beta cell ablation. Efficient beta cell elimination leading to severe hyperglycemia (>28 mmol/L), causes permanent diabetes with failed regeneration despite cell cycle engagement of surviving beta cells.

Hepatic targeting of the centrally active cannabinoid 1 receptor (CBR) blocker rimonabant via PLGA nanoparticles for treating fatty liver disease and diabetes.

Over-activation of the endocannabinoid/CBR system is a hallmark feature of obesity and its related comorbidities, most notably type 2 diabetes (T2D), and non-alcoholic fatty liver disease (NAFLD). Although the use of drugs that widely block the CBR was found to be highly effective in treating all metabolic abnormalities associated with obesity, they are no longer considered a valid therapeutic option due to their adverse neuropsychiatric side effects. Here, we describe a novel nanotechnology-based drug delivery system for repurposing the abandoned first-in-class global CBR antagonist, rimonabant, by encapsulating it in polymeric nanoparticles (NPs) for effective hepatic targeting of CBRs, enabling effective treatment of NAFLD and T2D.
