Since phosphorylations of the β2-adrenoceptors are probably important in inducing desensitization, we sought to investigate the importance of phosphorylation events by targeting protein phosphatases (PPs) in mast cells. To this end, the effects of the inhibitor of on the functional desensitization of β-adrenoceptor-mediated responses in mast cells were investigated. In this study the effects of PP inhibitors on the inhibition of histamine release from HLMC, on β-agonists in mast cells and on desensitization were investigated. Long-term exposure of mast cells to both isoprenaline and salbutamol substantially reduced the extent to which isoprenaline inhibited histamine release. Pretreatments of up to 24 h with inhibitors alone had no effect on immunoglobulin E-mediated histamine release. Shorter (≤4 h) pretreatments had little effect on the activity of isoprenal...

In this article, we systematically reviewed the studies that indicate calcium/calmodulin kinase II (CaMKII) is a ubiquitous molecule among different enzymes involved in human long-term memory and the main downstream signaling pathway of long-term memory. All of the observational, case-control and review studies were considered and evaluated by the search engines PubMed, Cochrane Central Register of Controlled Trials and ScienceDirect Scopus between 1990 and February 2015. We did not carry out meta-analysis. At the first search, it was fined 1015 articles which included "synaptic plasticity" OR "neuronal plasticity" OR "synaptic density" AND memory AND "molecular mechanism" AND "calcium/calmodulin-dependent protein kinase II" OR CaMKII as the keywords. A total of 335 articles were dupli...

Methods: We conducted a cross sectional study, in which information of every patient with tramadol toxicity admitted in Noor hospital ward of toxicology (Isfahan, Iran) were gathered and analyzed. Finding: From 184 cases, 141 (76.6%) were men. The mean age of the patients was 24 ± 7 years. Forty percent of patient had positive history of substance abuse. Eighty four cases (45.6%) were with coingestion. Thirty four percent of patients had chronic ingestion of tramadol. The most common chief complaint was central nervous system (CNS) depression (57%) followed by seizure (25%), bradypnea (18%), tachycardia (25%), and hypertension (7%). Active charcol...

We performed a study on the treatment outcome of acute methamphetamine intoxication in a referral tertiary care University hospital in Iran. In this hospital-based, retrospective study which was carried out from 2012 to 2013, medical records of all patients aged 18 to 65 years who were admitted with a reliable history and clinical diagnosis of acute methamphetamine intoxication were abstracted and analyzed. Patients' data included gender, age, type and route of poisoning, clinical manifestations, duration of hospitalization, and the treatment outcome. ANOVA, Chi-square, and binary logistic regression statistical tests were used for data analysis. A total of 129 patients with a mean age of 30.70 ± 0.93 (mean ± standard error), including 111 (86%) males, had been fully evaluated. Most of the patients had intentional poisoning (93.7%). In 42.6% of patients, inhalation was the main route of exposure. Most of the patients had complete improvement without any complication (89.1%). Age (odds ratio [OR], 1.05; 95% confidence interval [95% CI] 1.006-1.099), suicide history (OR, 30.33; 95% CI 3.11-295.24), route of poisoning ([ingestion: OR, 0.21; 95% CI 0.05-0.87], [inhalation: OR, 0.19; 95% CI 0.04-0.78]), and pulmonary system manifestations (OR 1.84; 95% CI 1.15-2.93) were predictive in patients outcome (P < 0.05). Methamphetamine poisoning was more common in males with intentional poisoning. Age, past history of suicide, route of poisoning, and pulmonary manifestations on admission could be considered as important predictive factors in patients' outcome.

This is an important mechanism in the regulation of intracellular signal transduction pathways in many cells. Phosphatases play a key role in regulating signal transduction. It is known that phosphatases are specific for cleavage of either serine-threonine or tyrosine phosphate groups. To date, numerous compounds have been identified. This paper reviews the classification, roles and pharmacological of protein serine/threonine phosphates.

Because of high accessibility of people to different medications in our society, one of the easiest ways for suicide is intentional self-poisoning with medications. Therefore, the aim of this study was to determine the rate of suicide with respect to influencing social factors on patients with intentional self-poisoning. This was an analytic-descriptive prospective study. All study data were collected through a checklist in patients with intentional self-poisoning who had been referred to referral hospital within 2011-2012. A total of 400 patients (60% female) were evaluated. Age average ± standard deviation of participants was 22.57 ± 9.20 years. About 78.2% had high school degree or less. Nearly 27.8% of all happened suicides take place as a result of family disputes, marital problems (21%) and poverty (11.5%). Love issues with a rate of 10.3% were set in the...

Pharmacists, as the most available member of medical team have a unique role in patient education for appropriate use of contraceptive methods. In this study, we assessed the pharmacists' knowledge about emergency contraception. A researcher made questionnaire was developed and used according to national guide line and electronic databanks. A group of experts and pharmacists validated the questionnaire. Reliability was measured by Half-Split Test. The questionnaires were filled by pharmacists. Average knowledge score were 8.12 ± 0.28 for women and 7.83 ± 0.31 for men (from a maximum of 15) which showed no significant difference between men and women (P = 0.492). There was no significant difference between pharmacists who had precipitated in continuing education programs and that of those who had not (P = 0.286). Scores of pharmacists who graduated 13 years ago o...

The current drug interventions are not efficient or need critical care as well. This study compares the clinical role of midazolam and diazepam for the management of agitation due to inappropriate use of naltrexone. In this double-blind randomized controlled clinical trial, 44 agitated addicts, who did not use any type of benzodiazepine, not on systematic central nervous system depressant drugs, without any known hypersensitivity to diazepam, midazolam, or any other component of their formulation and had no evidence for the need of critical care, were enrolled. An i.v. stat dose of 0.1 mg/kg diazepam and 0.1 mg/kg stat dose of midazolam and a 0.1 mg/kg/h infusion of these drugs were administered for different groups of patients, respectively. Agitation scores were recorded at 30, 60, 120 min after the start of drug administration using Richmond Agitatio...

Because of high accessibility of people to different drugs in our society, one of the easiest ways of suicide is intentional self-poisoning. In this study, demographic factors and health status of the patients with intentional self-poisoning were evaluated. A cross-sectional study was conducted in the poisoning referral center on 384 patients aged 15-40 years who committed intentional self-poisoning. Information was gathered using two questionnaires about demographic characteristics and the general health status of the patients. 70.5% of the patients had easy accessibility to drugs. Most of the patients were women (62.5%) and single (51%). History of psychological disease was demonstrated in 82.5% of patients. In terms of general health status, the most common problems were social dysfunction (97.57%) and depression (88.9%). Easy accessibility to drugs and psychological problems may increas...
