Serotonin toxicity is a potentially life-threatening condition associated with increased serotonergic activity in the central nervous system. It is seen with therapeutic medication use, intentional self-poisoning and inadvertent interactions (SSRI-isoniazid). Although this pathology is increasingly common, it is not well recognized by physicians and manifestations may be wrongly attributed to another cause. The aim of this paper is to describe the clinical picture of a patient, to collaborate on diagnosis and to improve medical care of these patients...

Paul M Palevsky
Acute renal replacement therapy is one of the most common interventions provided by nephrologists, however, data on the quality of training provided to nephrology fellows is limited. Extensive curricula for acute renal replacement therapy and the management of poisonings and intoxications have been published, but personal experience suggests that there are significant opportunities to improve training. Particular areas to be considered include the use of novel technologies for assessment of volume status, greater emphasis on the dosing of medications during acute renal replacement therapy, greater training in assessing and tailoring treatment to the goals of care of the individual patient, incorporation of continuous quality improvement tools into the management of acute renal replacement therapy programs and development of robust simulation training to augment training...

INTRODUCTION: Carbamate and organophosphate pesticides inhibit acetylcholinesterase, and poisoning leads to respiratory depression. Thus, involvement in sleep apnea is plausible, but no data exist at lower levels of exposure. Other pesticides could impact sleep apnea by different mechanisms but have not been studied. Our study examines the associations between pesticide exposure and sleep apnea among pesticide applicators from a US farming population. PARTICIPANTS AND METHODS: We analyzed data from 1569 male pesticide applicators, mostly farmers, from an asthma case-control study nested within the prospective Agricultural Health Study...

BACKGROUND: In the last decade, the concept of uncharged reactivators potentially able to penetrate the CNS has been introduced as an alternative to the classic charged oxime reactivators. However, this concept brings with it several associated drawbacks such as higher lipophilicity, difficulty in administration, lower affinity to cholinesterases, and higher toxicity risk. OBJECTIVE: In this study we compare data obtained for a set of five classic charged reactivators and a set of three recently published uncharged oximes supplemented by two novel ones...

Toxicology is a science of poisonings by xenobiotics and endogenous physiological changes. Its empiric roots may be traced back to the emerging of the human race because the most important pledge of our predecessors' survival was the differentiation between eatable and poisonous plants and animals. In the course of social evolution, there were three main fields of using poisons: 1) hunting and warfare, 2) to settle social tensions by avoiding military conflicts through hiding strategy of eliminating enemies by toxic substances, 3) medicines applied first as anti-poisons and later by introducing strong substances to defeat diseases, but paradoxically active euthanasia is also a part of the whole story...

Attempted murder by repeated poisoning is quite rare. The authors describe the case of a 62-year-old man who was admitted to an intensive care unit (ICU) for neurological disturbances complicated by inhalation pneumopathy. He presented a loss of consciousness while his wife was visiting him at the ICU (H0). Forty-eight hours later (H48), police officers apprehended the patient's wife pouring a liquid into his fruit salad at the hospital. Toxicological analyses of a blood sample and the infusion equipment (H0), as well as the fruit salad and its container (H48), confirmed the attempted poisoning with cyamemazine (H0) and hydrochloric acid (H48)...

The reactivity of various Pd ensembles on the Au-Pd(100) alloy catalyst toward CO oxidation was investigated by using density functional theory (DFT). This study was prompted by the search for efficient catalysts operating at low temperature for the CO oxidation reaction that is of primary environmental importance. To this aim, we considered Pd modified Au(100) surfaces including Pd monomers, Pd dimers, second neighboring Pd atoms, and Pd chains in a comparative study of the minimum energy reaction pathways...

Retinoic acid (RA) is a vital morphogen for early patterning and organogenesis in the developing embryo. RA is a diffusible, lipophilic molecule that signals via nuclear RA receptor heterodimeric units that regulate gene expression by interacting with RA response elements in promoters of a significant number of genes. For precise RA signaling, a robust gradient of the morphogen is required. The developing embryo contains regions that produce RA, and specific intracellular concentrations of RA are created through local degradation mediated by Cyp26 enzymes...

As an excellent hydrogen storage medium, methanol has many advantages, such as high hydrogen content (12.6 wt%), low-cost and availability from biomass or photocatalysis. However, conventional methanol-water reforming usually proceeds at high temperature. In this research, we successfully designed a new effective strategy to generate hydrogen from methanol at near-room temperature. The strategy involves two main procedures, which are CH3OH→HCOOH→H2 and NADH→HCOOH→H2. The first procedure (CH3OH→HCOOH→H2) is performed by alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH) and the Ir-catalyst...

Acetaminophen poisoning increases cytochrome P450 2E1 expression and reactive oxygen species production, which may lead to maladaptive myocardial remodeling and congestive heart failure (CHF). We conducted a nationwide cohort study to investigate the incidence and risk of CHF in patients with acetaminophen poisoning. We identified a cohort of adult patients with newly diagnosed acetaminophen poisoning in the inpatient claims of the Taiwan National Health Insurance Research Database for the 1998-2011 period...

Consumption of Cassia occidentalis (CO) seeds has been associated with the hepatomyoencephalopathy (HME) in children. Recently, we have characterized the toxic anthraquinones (AQs) such as Emodin, Rhein, Aloe-emodin, Chrysophanol and Physcion in CO seeds and detected these moieties in the bio fluids of CO poisoning cases. As AQs were detected in the serum of HME patients, their interaction with key biomolecules including protein, DNA and glutathione (GSH) is imperative. In this regard, we have previously reported the interaction of these AQs with serum albumin protein and their subsequent biological effects...

REVIEW
James H Diaz
Amatoxins are produced primarily by 3 species of mushrooms: Amanita, Lepiota, and Galerina. Because amatoxin poisonings are increasing, the objective of this review was to identify all amatoxin-containing mushroom species, present a toxidromic approach to earlier diagnoses, and compare the efficacies and outcomes of therapies. To meet these objectives, Internet search engines were queried with keywords to select peer-reviewed scientific articles on amatoxin-containing mushroom poisoning and management. Descriptive epidemiological analyses have documented that most mushroom poisonings are caused by unknown mushrooms, and most fatal mushroom poisonings are caused by amatoxin-containing mushrooms...

Micromorphology and atomic arrangement on ligament surface of nanoporous metals play a vital role in maintaining the structural stability, adjusting the reaction interface and endowing the functionality. Here we offer an instructive scientific understanding for temperature-induced surface reconstruction and interface structure evolution on ligament of nanoporous copper (NPC) based on systematically experimental observations and theoretical calculations. The results show that with dealloying temperature increasing, ligament surface micromorphology of NPC evolves from smooth to irregularity and to uniformly compressed semisphere, and finally to dispersed single-crystal nanoparticles accompanying with significant changes of interface structure from coherence to semi-coherence and to noncoherence...
