RNA editing of the 5-HT2C receptor in the central nucleus of the amygdala is involved in resilience behavior.

Post-traumatic-stress-disorder (PTSD) is a stress-related condition that may develop after exposure to a severe trauma-event. One of the core brain areas that is considered to be a key regulatory region of PTSD is the amygdala. Specifically, the central amygdala (CeA) is involved in emotion processing and associative fear learning memory, two main circuits involved in PTSD.

Purifying selection of long dsRNA is the first line of defense against false activation of innate immunity.

Background: Mobile elements comprise a large fraction of metazoan genomes. Accumulation of mobile elements is bound to produce multiple putative double-stranded RNA (dsRNA) structures within the transcriptome. These endogenous dsRNA structures resemble viral RNA and may trigger false activation of the innate immune response, leading to severe damage to the host cell.

Differential lung ventilation for increased oxygenation during one lung ventilation for video assisted lung surgery.

Background: One lung ventilation (OLV) is the technique used during lung resection surgery in order to facilitate optimal surgical conditions. OLV may result in hypoxemia due to the shunt created. Several techniques are used to overcome the hypoxemia, one of which is continuous positive airway pressure (CPAP) to the non-dependent lung.

Pre-reproductive stress and fluoxetine treatment in rats affect offspring A-to-I RNA editing, gene expression and social behavior.

Adenosine to inosine RNA editing is an epigenetic process that entails site-specific modifications in double-stranded RNA molecules, catalyzed by adenosine deaminases acting on RNA (ADARs). Using the multiplex microfluidic PCR and deep sequencing technique, we recently showed that exposing adolescent female rats to chronic unpredictable stress before reproduction affects editing in the prefrontal cortex and amygdala of their newborn offspring, particularly at the serotonin receptor 5-HT2c (encoded by . Here, we used the same technique to determine whether post-stress, pre-reproductive maternal treatment with fluoxetine (5 mg/kg, 7 days) reverses the effects of stress on editing.

A-to-I RNA editing in the rat brain is age-dependent, region-specific and sensitive to environmental stress across generations.

Background: Adenosine-to-inosine (A-to-I) RNA editing is an epigenetic modification catalyzed by adenosine deaminases acting on RNA (ADARs), and is especially prevalent in the brain. We used the highly accurate microfluidics-based multiplex PCR sequencing (mmPCR-seq) technique to assess the effects of development and environmental stress on A-to-I editing at 146 pre-selected, conserved sites in the rat prefrontal cortex and amygdala. Furthermore, we asked whether changes in editing can be observed in offspring of stress-exposed rats.

The effect of 'Out of hours surgery Service' in Israel on hip fracture fixation outcomes: a retrospective analysis.

Background: 'Out of Hours Surgery Service' (OHSS) was implemented in Israel, amongst other reasons, in order to reduce the time interval between hospital admission and surgery and consequently improve outcomes. The OHSS is currently operated in the public hospitals in Israel. In this study we compared the data of patients before and after OHSS implementation to determine its efficacy in improving patient care.

Abnormalities in A-to-I RNA editing patterns in CNS injuries correlate with dynamic changes in cell type composition.

Adenosine to Inosine (A-to-I) RNA editing is a co- or post-transcriptional mechanism that modifies genomically encoded nucleotides at the RNA level. A-to-I RNA editing is abundant in the brain, and altered editing levels have been reported in various neurological pathologies and following spinal cord injury (SCI). The prevailing concept is that the RNA editing process itself is dysregulated by brain pathologies.

Indications for Elective Tracheostomy in Reconstructive Surgery in Patients With Oral Cancer.

Background: Oral cancer surgery carries a high risk of upper airway obstruction; yet optimal airway management approach remains controversial.

Aim Of Study: The purpose of the present study was to evaluate the use of tracheostomy in oncological patients undergoing oral cancer surgery with intra oral flap reconstruction.

Methods: The study cohort included 75 patients with oral cancer, who underwent major intraoral resections and reconstruction with vascularized flaps.

Expanding preconception carrier screening for the Jewish population using high throughput microfluidics technology and next generation sequencing.

Background: Genetic screening to identify carriers of autosomal recessive diseases has become an integral part of routine prenatal care. In spite of the rapid growth of known mutations, most current screening programs include only a small subset of these mutations, and are performed using diverse molecular techniques, which are generally labor-intensive and time consuming. We examine the implementation of the combined high-throughput technologies of specific target amplification and next generation sequencing (NGS), for expanding the carrier screening program in the Israeli Jewish population as a test case.

Activation-Induced Cytidine Deaminase Links Ovulation-Induced Inflammation and Serous Carcinogenesis.

In recent years, the notion that ovarian carcinoma results from ovulation-induced inflammation of the fallopian tube epithelial cells (FTECs) has gained evidence. However, the mechanistic pathway for this process has not been revealed yet. In the current study, we propose the mutator protein activation-induced cytidine deaminase (AID) as a link between ovulation-induced inflammation in FTECs and genotoxic damage leading to ovarian carcinogenesis.

The Role of Fine Needle Aspiration in the Diagnosis of Parotid Gland Tumors: Correlation With Preoperative Computerized Tomography Tumor Size.

The role of fine needle aspiration cytology (FNAC) in the diagnosis of parotid gland masses is still controversial, regarding its sensitivity and specificity that vary between 41% and 100% and between 86% and 100% respectively.The aim of this study was to identify the specificity and sensitivity of FNAC of parotid gland tumors in relation to the tumor size as characterized preoperatively by computer tomography. The medical files of 79 patients whom were referred to the MaxilloFacila Surgery Department, Rambam medical center, over a 10.

Reduced levels of protein recoding by A-to-I RNA editing in Alzheimer's disease.

Adenosine to inosine (A-to-I) RNA editing, catalyzed by the ADAR enzyme family, acts on dsRNA structures within pre-mRNA molecules. Editing of the coding part of the mRNA may lead to recoding, amino acid substitution in the resulting protein, possibly modifying its biochemical and biophysical properties. Altered RNA editing patterns have been observed in various neurological pathologies.

Fmrp Interacts with Adar and Regulates RNA Editing, Synaptic Density and Locomotor Activity in Zebrafish.

Fragile X syndrome (FXS) is the most frequent inherited form of mental retardation. The cause for this X-linked disorder is the silencing of the fragile X mental retardation 1 (fmr1) gene and the absence of the fragile X mental retardation protein (Fmrp). The RNA-binding protein Fmrp represses protein translation, particularly in synapses.

Airway Management of the Patient with Maxillofacial Trauma: Review of the Literature and Suggested Clinical Approach.

According to the Advanced Trauma Life Support recommendations for managing patients with life-threatening injuries, securing the airway is the first task of a primary caregiver. Airway management of patients with maxillofacial trauma is complex and crucial because it can dictate a patient's survival. Securing the airway of patients with maxillofacial trauma is often extremely difficult because the trauma involves the patient's airway and their breathing is compromised.

Hypotensive anesthesia versus normotensive anesthesia during major maxillofacial surgery: a review of the literature.

Steady blood pressure within normal limits during surgery is one of the markers of the ideal and skillful anesthesia. Yet, reduced blood pressure is advantageous in some settings because it can contribute to a reduction in overall blood loss and improve the surgical field conditions. Controlled hypotension during anesthesia or hypotensive anesthesia is often used in major maxillofacial operations.

Subcutaneous Emphysema following Emergent Surgical Conventional Tracheostomy.

In maxillofacial surgery, tracheostomy is indicated in congenital, inflammatory, oncologic, or traumatic respiratory obstruction. In traumatic cases, however, it is sometimes hard to implement. We describe subcutaneous emphysema following emergent surgical conventional tracheostomy performed after stab injury to the floor of the mouth.

The use of VivaSight™ single lumen endotracheal tube in morbidly obese patients undergoing laparoscopic sleeve gastrectomy.

Background: The population of obese patients is progressively growing and bariatric operations are becoming increasingly common. Morbidly obese patients require special anesthetic care and are often considered to be difficult to ventilate and intubate. The VivaSight™ Single Lumen tube is an endotracheal tube with a camera embedded in its tip.

A-to-I RNA editing occurs at over a hundred million genomic sites, located in a majority of human genes.

RNA molecules transmit the information encoded in the genome and generally reflect its content. Adenosine-to-inosine (A-to-I) RNA editing by ADAR proteins converts a genomically encoded adenosine into inosine. It is known that most RNA editing in human takes place in the primate-specific Alu sequences, but the extent of this phenomenon and its effect on transcriptome diversity are not yet clear.

Automated analysis of immunoglobulin genes from high-throughput sequencing: life without a template.

Background: Immunoglobulin (that is, antibody) and T cell receptor genes are created through somatic gene rearrangement from gene segment libraries. Immunoglobulin genes are further diversified by somatic hypermutation and selection during the immune response. Studying the repertoires of these genes yields valuable insights into immune system function in infections, aging, autoimmune diseases and cancers.

Factors associated with adverse outcome following urologic surgery in patients aged 80 years and older.

Background And Aims: This study was designed to find predictors for adverse post-operative outcomes in elderly patients aged 80 years and older, who underwent urologic surgery.

Methods: In this prospective observational study, we analysed data, including age, gender, American Society of Anesthesiologists (ASA) class, co-morbidities, number of regular medications, type and extent of surgery, type of anesthesia, duration of surgery and hospitalization, post-operative morbidity and mortality. We studied the correlations between each pre- and intra-operative parameter to the consequence, to find predictors for adverse outcome.

Core decompression and alendronate treatment of the osteonecrotic rat femoral head: computer-assisted analysis.

Femoral head avascular necrosis is a process leading to femoral head deformity and osteoarthritic changes in the hip joint. Alendronate slows down bone resorption and remodelling in rats, while core decompression hastens the healing processes. We evaluated the influence of daily alendronate treatment on the rat femoral head shape after surgical osteonecrosis with core decompression, compared with controls.

Pulmonary Complications following Percutaneous Nephrolithotomy: A Prospective Study.

Introduction: Pulmonary complications may occur in the post-operative period and are a significant cause of morbidity and mortality in patients undergoing anesthesia and surgery. Complication rates vary according to different procedures and different types of anesthesia and may be affected by the patient condition. The purpose of this study was to examine pulmonary complications following percutaneous nephrolithotomy (PCNL) and to search for associations between the pre- and intra-operative factors and the risk of post-operative pulmonary complications (PPC).

[Anesthesia and peri-operative care of the elderly patient].

With raised life expectancy, there is a constant elevation in the percentage of elderly people in the general population. Consequently, the age of the surgical patient increases. This progressive process results in operating on patients who were considered 'too old for surgery' a decade ago.
