Acute poisoning with OPs may lead to a range of neurological effects, which cannot be explained by AChE inhibition alone. Several OPs interact directly with cholinergic receptors in mammals, but such data does not exist for invertebrates. The aim of current study was to investigate the direct and indirect effects of diazinon on the contractions of rat ileum and to compare those effects on the nervemuscle preparation of the Ascaris suum. In the presence of increasing concentrations of diazinon (3, 10 and 30nM), EFS-induced ileal contractions were increased significantly...

Background: Greece has been in the grip of a severe economic crisis since 2008. It is well known that suicide attempts and actual suicides increase during periods of recession and austerity. The main aim of this study was to examine the economic crisis in relation to recorded suicide attempts in Chania, Greece, from 2008 to 2015, also taking unemployment rates into consideration. Methods: During the research period from January 1, 2008, to December 31, 2015, 436 suicide attempts (females: n = 305 and males: n = 131) were recorded in the archives of the General Hospital of Chania...

INTRODUCTION: Exposure to carbon monoxide (CO) is among the most common causes of acute and chronic poisonings worldwide. The crucial point of treatment of such acute poisonings is to eliminate CO from the body as fast as possible. There are currently two approaches to the management of the CO intoxication: hyperbaric oxygen therapy (HOT) and normobaric oxygen therapy (NOT). HOT is highly effective and capable of achieving the CO elimination half-time (T½) as low as 15 minutes. Unfortunately this method is expensive and not always readily available...

Sulfur mustard (SM) is a strong blistering, highly reactive, lipophilic chemical war agent that causes injury in different organs including the skin, eyes and respiratory tract. The Eyes are especially susceptible to the consequences of SM poisoning because of the aqueous and mucosal nature of conjunctiva and cornea. DNA alkylation and depletion of glutathione, are the most important mechanisms of SM action in the eye injuries. Acute clinical symptoms are including decrease in visual acuity, dryness, photophobia, blepharospasm, conjunctivitis and complaints of foreign body sensation and soreness that gradually progress to severe ocular pain...

A methodology by coupling a microfluidic-batch process with in situ carbon-black mixing, successive annealing and de-alloying post-treatment was developed for engineering surface and interface microstructures of FePt/C nanocomposites. Ultra-small angular FePt nanocrystals rich in vertexes/terraces/steps and with Pt contents gradually increasing from the inner to the outer part can be synthesized at certain Fe/Pt atomic ratios (2/1 or 1.1/1), which can directly grow on carbon-black for enhanced nanocrystal-carbon interface interaction by introducing the in situ carbon-black mixing process...

INTRODUCTION: Bongkrekic acid (BA) has a unique mechanism of toxicity among the mitochondrial toxins: it inhibits adenine nucleotide translocase (ANT) rather than the electron transport chain. Bongkrekic acid is produced by the bacterium Burkholderia gladioli pathovar cocovenenans (B. cocovenenans) which has been implicated in outbreaks of food-borne illness involving coconut- and corn-based products in Indonesia and China. Our objective was to summarize what is known about the epidemiology, exposure sources, toxicokinetics, pathophysiology, clinical presentation, and diagnosis and treatment of human BA poisoning...

OBJECTIVES: To describe trends in suicides with opioid poisoning noted as a contributing cause of death. METHODS: Using National Vital Statistics data (1999-2014), we calculated age-adjusted rates of suicide with opioid poisoning (International Classification of Diseases, Tenth Revision codes T40.0-T40.4) per 100 000 population per year and annual percentage change (APC) in rates. We used Joinpoint regression to examine trends in suicide rates and proportion of suicides involving opioids...

Cancer patients receiving anthracycline-based chemotherapy are at risk to develop life-threatening chronic cardiotoxicity with the pathophysiological mechanism of action not fully understood. Besides the most common hypothesis that anthracycline-induced congestive heart failure (CHF) is mainly caused by generation of reactive oxygen species, recent data point to a critical role of topoisomerase II beta (TOP2B), which is a primary target of anthracycline poisoning, in the pathophysiology of CHF. As the use of the only clinically approved cardioprotectant dexrazoxane has been limited by the FDA in 2011, there is an urgent need for alternative cardioprotective measures...

Poisoning through pediatric skin leading to acute systemic symptoms is a relatively uncommonly reported phenomenon. Systemic toxicity through the skin typically occurs by direct contact between therapeutic or non-therapeutic topical agents and the skin. Though uncommon, poisoning through pediatric skin can have significant consequences and must be recognized so the offending agent may be discontinued and appropriate treatment initiated. We performed a literature search for all article types between 1950 and April 2016 to provide a single source of detectable cases of acute toxicity in pediatric patients due to percutaneous exposure...

The SrrAB two-component regulatory system (TCRS) positively influences the transcription of genes involved in aerobic respiration in response to changes in respiratory flux. Hydrogen peroxide (H2O2) can arise as a byproduct of spontaneous interactions between dioxygen and components of respiratory pathways. H2O2 damages cellular factors including protein associated iron-sulfur cluster prosthetic groups. We found that a Staphylococcus aureus strain lacking the SrrAB two-component regulatory system (TCRS) is sensitive to H2O2 intoxication...

Carbon monoxide is known as the "silent murderer" because it is a colorless and odorless gas. According to these characteristics, toxicity goes unnoticed which makes the diagnosis difficult. In most cases, the cold periods and group poisoning make suspect its presence because inappropriate heat both in home or public environments. Our goal is to inform about a mass carbon monoxide poisoning in a children's parties room using a combustion source installed, not for the purpose of heating, but as a supply of light (generator), emphasizing that it can occur in any time of the year...
