BACKGROUND: Anhedonia, the decreased interest and pleasure, is often described as 'flat' or 'blunted' positive affect (PA). Yet, little is known about PA functioning in anhedonic individuals' daily lives. The current study investigates PA reactivity to pleasurable experiences in anhedonia together with its relevant temporal dynamics (i.e., variability, instability, and inertia), and expands current knowledge by exploring the role of arousal therein. METHODS: Using the Experience Sampling Method (ESM), we collected 90 assessments of real-life PA experiences across 30 days in 18-24 year old individuals with anhedonia (N=69) and without anhedonia (N=69)...

Adverse effects (AEs) are an important factor in antidepressant treatment decision-making, though common AE profiles from clinical trial research highlight physical AEs to the neglect of emotional and behavioral AEs. First-hand accounts of antidepressant users on the Internet can supplement AE profiles with information gained from real-world treatment experiences. We examined online user reviews of two older (escitalopram; duloxetine) and two newer (vilazodone; vortioxetine) antidepressants for differences in their AE profiles and determined which categories of AEs were associated with users' satisfaction...

Arpin, a negative regulator of the actin-related protein-2/3 (Arp2/3) complex, is downregulated and predicts poor prognosis in breast cancer patients. However, its biological relevance in breast cancer is still unclear. This study was conducted to investigate the roles of Arpin in breast cancer growth and invasion. We overexpressed Arpin expression in MCF-7 and MDA-MB-231 breast cancer cells and examined the effects of restoration of Arpin on cell proliferation, colony formation, cell cycle distribution, invasion in vitro and tumorigenesis in vivo...

Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disorder known to cause progressive joint destruction. Over time, untreated RA can lead to pain and increasing disability, making orthopedic intervention necessary. The treatment of RA revolves around a variety of medications that blunt the overall immune response. However, this may increase the risk of infection and impair wound healing. Given the nature of this disease, orthopedists frequently encounter patients with RA in the operative setting. To optimize surgical outcomes, orthopedists must carefully manage and pay special attention to the adverse side effects of the complicated medication regimens of these patients perioperatively...

INTRODUCTION: Illegal immigration from Africa to Israel expanded in recent years, bringing illegal immigrants, mostly from Eritrea and Sudan. No data regarding the ophthalmic conditions of this population was previously published. AIMS: To delineate reasons for ophthalmologic emergency room visits and hospitalizations in the ophthalmology department at a tertiary center in Tel Aviv, Israel. METHODS: In this retrospective study we reviewed the records of patients of Eritrean and Sudanese origin arriving at the ophthalmic emergency room at the Tel Aviv Sourasky Medical Center between June 2012 and August 2012 and hospitalized in the ophthalmology ward between August 2011 and August 2012...

Geriatric trauma constitutes an increasingly recognized problem. Aging results in a progressive decline in cellular function which leads to a loose of their capacity to respond to injury. Some medications commonly used in this population can mask or blunt the response to injury. Falls constitute the most common cause of trauma and the leading cause of trauma-related deaths in this population. Falls are complicated by the widespread use of antiplatelets and anticoagulants, especially in patients with brain injury...

Innate immune responses play a major role in the control of herpes simplex virus (HSV) infections, and a multiplicity of mechanisms have emerged as a result of human evolution to sense and respond to HSV infections. HSV in turn has evolved a number of ways to evade immune detection and to blunt human innate immune responses. In this review, we summarize the major host innate immune mechanisms and the HSV evasion mechanisms that have evolved. We further discuss how disease can result if this equilibrium between virus and host response is disrupted...

Vascular calcification is established to be a critical factor in diabetes mellitus, which causes cardiovascular and amputation complication of diabetic patients. OPG/RANKL/RANK axis serves as a regulatory role in vascular calcification. Ghrelin, an endogenous ligand of growth hormone secretagogue receptor (GHSR), has been reported to exhibit potent cardiovascular protective effects. However, the role of ghrelin in the regulation of diabetic vascular calcification is still elusive. Here, we reported the role of ghrelin and its relationship with OPG/RANKL/RANK system in patients with diabetic foot amputation...

If oil sands process-affected water (OSPW) is to be returned to the environment, a desire is that it not adversely affect aquatic life. We investigated whether a relevant model fish (rainbow trout; Oncorhynchus mykiss) could detect OSPW using its olfactory sense (smell), and whether exposure to it would result in behavioural changes. We also investigated whether ozonation of OSPW, which lowers the concentration of organic compounds attributed with toxicity (naphthenic acids), would ameliorate any observed adverse effects...

OBJECTIVE: To determine if beta-(β)-blockers improve outcomes after acute traumatic brain injury (TBI). BACKGROUND: There have been no new inpatient pharmacologic therapies to improve TBI outcomes in a half-century. Treatment of TBI patients with β-blockers offers a potentially beneficial approach. METHODS: Using MEDLINE, EMBASE, and CENTRAL databases, eligible articles for our systematic review and meta-analysis (PROSPERO CRD42016048547) included adult (age ≥ 16 years) blunt trauma patients admitted with TBI...

Autoamputated ovary with mature cystic teratoma (MCT) is a rarely reported gynecologic entity with an unknown prevalence. A 34-year-old woman referred to our clinic for presumed left ovarian tumor. Pelvic examination, ultrasonography and computed tomography scan revealed a 5-cm, cystic ovarian mass with calcification and fat component, and tumor markers were as follows, cancer antigen (CA) 125; 10.4 U/mL, CA19-9; 2 U/mL. Laparoscopy was performed. The mass was identified in the left adnexal region without any ligamentous or direct connection with the pelvic organs...

Craniomaxillofacial injuries can be complex, requiring a multidisciplinary approach. The primary survey is always the first step in trauma management prior to proceeding with further evaluation and treatment. A 26-year-old man presented with a penetrating nail gun injury through the oral and nasal cavities. He did not present in extremis but required elective endotracheal intubation for intraoperative assessment and treatment. Airway management was enhanced by the use of lingual nerve and inferior alveolar nerve blocks via the Vazirani-Akinosi technique to maintain spontaneous respiration while the tongue was distracted from the palate...

The regulatory control of cardiac endoplasmic reticulum (ER) stress is incompletely characterized. As ER stress signaling upregulates the E3-ubiquitin ligase Parkin, we investigated the role of Parkin in cardiac ER stress. Parkin knockout mice exposed to aortic constriction-induced cardiac pressure-overload or in response to systemic tunicamycin (TM) developed adverse ventricular remodeling with excessive levels of the ER regulatory C/EBP homologous protein CHOP. CHOP was identified as a Parkin substrate and its turnover was Parkin-dose and proteasome-dependent...

Metformin is used clinically to reduce fasting glucose with minimal effects on postprandial glucose. Postmeal exercise reduces postprandial glucose and may offer additional glucose-lowering benefit beyond that of metformin alone, yet controversy exists surrounding exercise and metformin interactions. It is currently unknown how postmeal exercise and metformin monotherapy in combination will affect postprandial glucose. Thus, we examined the independent and combined effects of postmeal exercise and metformin monotherapy on postprandial glucose...

Rational therapeutic approaches based on synthetic lethality may improve cancer management. Based on a high-throughput drug screen, we provide preclinical proof of concept that targeting the mitochondrial Hsp90 chaperone network (mtHsp90) and inhibition of Bcl-2, Bcl-xL and Mcl-1 is sufficient to elicit synthetic lethality in tumors recalcitrant to therapy. Our analyses focused on BH3 mimetics that are broad acting (ABT263 and Obatoclax) or selective (ABT199, WEHI-539 and A1210477), along with the established mitochondrial matrix chaperone inhibitor Gamitrinib-TPP...

Airway remodeling in asthma driven by inflammation involves proliferation of epithelial cells and airway smooth muscle (ASM), as well as enhanced extracellular matrix (ECM) generation and deposition, i.e. fibrosis. Accordingly, understanding pro-fibrotic mechanisms is important for developing novel therapeutic strategies in asthma. Recent studies, including our own, have suggested a role for locally-produced growth factors such as brain-derived neurotrophic factor (BDNF) in mediating and modulating inflammation effects...
