The metabolism of aromatic hydrocarbons by the organism forms products that cause cell death depending on the type of exposure. Benzene exposure has been linked to oxidative stress, hepatic damage, aplastic anemia and hematopoietic cancer as lymphoid and myeloid leukemia. However, there are not fast methods to evaluate chronically benzene exposure in human blood. The objective of this work was the evaluation of the correlation between oxidative damage with benzene exposure and the level of Cellular Plasma Membrane Stability (CPMS) in erythrocytes to use it as a future indicator to determine the grade of benzene intoxications...

Background: Intoxication by nerve agents could be prevented by using small acetylcholinesterase inhibitors (eg, pyridostigmine) for potentially exposed personnel. However, the serious side effects of currently used drugs led to research of novel potent molecules for prophylaxis of organophosphorus intoxication. Methods: The molecular design, molecular docking, chemical synthesis, in vitro methods (enzyme inhibition, cytotoxicity, and nicotinic receptors modulation), and in vivo methods (acute toxicity and prophylactic effect) were used to study bispyridinium, bisquinolinium, bisisoquinolinium, and pyridinium-quinolinium/isoquinolinium molecules presented in this study...

Photosynthetic organisms suffering from light stress have to cope with an increased formation of reactive short-chain aldehydes. Singlet oxygen generated from highly-charged reaction centres can peroxidise the poly-unsaturated fatty acid (PUFA)-rich thylakoid membranes they are embedded in. Lipid peroxides decay to release α,β-unsaturated aldehydes that are reactive electrophile species (RES). Acrolein is one of the most abundant and reactive RES produced in chloroplasts. Here, in the model chlorophyte alga Chlamydomonas reinhardtii, a clear concentration-dependent "distress" induced by acrolein intoxication was observed in conjunction with depletion of the glutathione pool...

Colibactins are hybrid polyketide-nonribosomal peptides produced by Escherichia coli , Klebsiella pneumoniae , and other Enterobacteriaceae harboring the pks genomic island. These genotoxic metabolites are produced by pks -encoded peptide-polyketide synthases as inactive prodrugs called precolibactins, which are then converted to colibactins by deacylation for DNA-damaging effects. Colibactins are bona fide virulence factors and are suspected of promoting colorectal carcinogenesis when produced by intestinal E...

INTRODUCTION: Alpha lipoic acid (ALA) is a potent antioxidant used to treat a variety of disorders. Although ALA is considered a very safe supplement and intoxication is very rare, acute high-dose ingestions can cause mortality. In this report, we discuss a very rare case of ALA intoxication to increase awareness of this issue. CASE REPORT: A 22-year-old female was referred to our emergency department with ALA intoxication after ingesting a total of 18g of ALA with a suicidal intention...

Pancreatitis consists in acute inflammation of the pancreas that is clinically characterized by abdominal pain. To make the diagnosis it is necessary the elevation of biochemical markers like pancreatic amylase or lipase. It is the most frequent pancreatic disease in both children and adults. Its presentation in the pediatric population is increasing and has several etiologies such as: infections, trauma, intoxication and metabolic diseases. Trauma mechanisms have been described: child maltreatment, falls, trauma with the bicycle handle and traffic accidents...

"Krokodil" is a home-made opioid drug obtained by synthesizing desomorphine from codeine and combining it with other low-cost additives. Initially introduced in the former Soviet countries, it was then imported to Western Europe as a heroin substitute. To our knowledge, this is the first report of an Italian case of lethal krokodil abuse, that occurred in a 39-year-old man, who died suddenly after transportation to the Emergency Department (ED) for hyperthermia associated with sweating, dyspnoea and tachycardia...

BACKGROUND: Altered mental status is a commonly evaluated problem in the ED. Ethanol intoxication is common, and prehospital history may bias emergency physicians to suspect this as the cause of altered mental status. Quantitative ethanol measurement can rapidly confirm the diagnosis, or if negative, prompt further evaluation. Our objective was to identify the etiologies of altered mental status in ED patients initially presumed to be intoxicated with ethanol but found to have negative quantitative ethanol levels...

The number of emerging novel stimulants modified based on beta-keto variations of amphetamine-like substances continues to rise. Dibutylone reports described in the medical and toxicological literature are limited, therefore little information is available in terms of quantitative confirmation or metabolism. During this study, authentic human specimens, including blood, urine, vitreous humor, oral fluid and liver were quantitatively and qualitatively analyzed for the presence of dibutylone and butylone, with paired case history and demographic information...

The use of commercial pesticides combinations increases the risk of intoxication in non-target aquatic organisms. Here, we investigate the potential of a commercial pesticide formulation containing (CYP) plus chlopyrifos (CPF) to induce oxidative damage on two fish species (common carp and zebrafish). Carp and zebrafish were exposed for 96 h under laboratory conditions. Fish were divided in three different groups: CTL, 0.3 μg L-1 or 0.6 μg L-1 of CYP and 0.5 or 1 μg L-1 of CPF in commercial formulation...

Previous studies have shown that cyclodextrin group medicines bind to various drugs. The hypothesis of our study is to determine whether sugammadex could bind to digoxin and delay the cardiovascular toxicity of that drug. Twenty-eight sedated Wistar rats were infused with digoxin at 3 mg/h (0.25 mg/ml). Five minutes after the start of infusion, animals were treated with a bolus of either 16 mg/kg (Sgdx16), 100 mg/kg (Sgdx100), or 1000 mg/kg (Sgdx1000) sugammadex. The control group infusion did not contain sugammadex...

Results of recent work from our labs and those of others have broadened perspectives on addiction beyond a human-specific, cognitive phenomenon. Addictive plant alkaloids are defensive compounds which have arisen to counter herbivory. With insects the true targets of the coevolutionary arms race, humans may be little more than collateral damage when impacted by 'human' drugs of abuse. The present paper summarizes recent contributions, with a primary focus on our own research in crayfish, where we characterize the behavioral and neural consequences resulting from chronic and acute exposure to psychostimulant and addictive drugs...

Chelation therapy is the mainstream treatment for heavy metal poisoning. Apart from this, therapy using antioxidant/herbal extracts are the other strategies now commonly being tried for the treatment. We have previously reported individual beneficial efficacy of nanoparticle mediated administration of an antioxidant like 'curcumin' and an arsenic chelator 'monoisoamyl 2,3-dimercaptosuccinic acid (MiADMSA)' for the treatment of arsenic toxicity compared to bulk drugs. The present paper investigates our hypothesis that a combination drug delivery therapy employing two nanosystems, a chelator and a strong antioxidant, may produce more pronounced therapeutic effects compared to individual effects in the treatment of arsenic toxicity...
