OBJECTIVE To evaluate the efficacy and safety of 5% imiquimod cream compared with vehicle in the treatment of actinic keratosis (AK). DESIGN Two phase 3 randomized, double-blind, parallel-group, vehicle-controlled studies. SETTING Twenty-six ambulatory care offices, including dermatologists in private practice or research centers. PATIENTS Four hundred ninety-two patients, 18 years and ol...

IMPORTANCE The immunopathogenic mechanisms of dry eye disease (DED), one of the most common ophthalmic conditions, is incompletely understood. Data from this prospective, double-masked, randomized trial demonstrate that targeting interleukin 1 (IL-1) by topical application of an IL-1 antagonist is efficacious in significantly reducing DED-related patient symptoms and corneal epitheliopathy. O...

This study tests the hypothesis that adenosine A2 receptor activation reduces reperfusion injury by inhibiting neutrophils in a canine model of ischemia and reperfusion. In 16 anesthetized, open-chest dogs, the left anterior descending coronary artery was ligated for 60 min and reperfused for 3 hr. An intracoronary infusion of either the selective adenosine A2 agonist CGS-21680 at 0.2 microgram...

The present study sought to examine whether repeated administration of the CB(1) receptor agonist WIN55,212-2 affected intracranial self-stimulation (ICSS) behavior and induced phenomena of tolerance or sensitization, similar to typical addictive drugs. Rats received intraperitoneal injections of vehicle for 5 days, vehicle or WIN55,212-2 (0.1, 0.3 or 1mg/kg) for 20 subsequent days, and vehicle...

We tested the effect of the antianginal agent ranolazine on ventricular arrhythmias in an ischemic model using two protocols. In protocol 1, anesthetized rats received either vehicle or ranolazine (10 mg/kg, iv bolus) and were subjected to 5 min of left coronary artery (LCA) occlusion and 5 min of reperfusion with electrocardiogram and blood pressure monitoring. In protocol 2, rats received eit...

There are controversial reports about the effect of granulocyte colony-stimulating factor (G-CSF) in peripheral nerve protection. Therefore, the present study aimed to investigate the effect of G-CSF on peripheral nerves in streptozotocin (STZ) induced diabetic rats. After STZ or vehicle injection, rats were divided into five groups (n=6) as follows: normal+vehicle, normal+G-CSF (50 µg/kg for 5...

this lecture introduces testing methods for the protection of children in vehicles. in order to reduce the fatalities and injuries of children in transportation state of the art child protection is mandatory. global laws and regulations such as ece or fmvss are introduced and compared with new car assessment programs (ncap). engineering tools and equipment to test according to global child prot...

background: motor vehicle crashes (mvc) are considered to be the most common safety challenge, causing more than a million deaths worldwide annually. objectives: the current study was aimed at identifying the etiological role of human and vehicle safety factors in road crashes, and their effects on the severity of injury and fatality in the sistan and baluchistan province, south east iran. pati...

background: evaluation of intra-city roads in terms of environmental factors of motor vehicle injuries can help us to better identify these factors and the share of each of the factors in injuries. therefore, this study was conducted to determine the high injury areas and the risk factors of motor vehicle crashes resulting in injury and death in tehran, the capital city of iran, from november 2...

objective(s): brain edema is one of the most serious causes of death within the first few days after trauma brain injury (tbi). in this study we have investigated the role of shilajit on brain edema, blood-brain barrier (bbb) permeability, intracranial pressure (icp) and neurologic outcomes following brain trauma.   materials and methods: diffuse traumatic brain trauma was induced in rats by dr...
