Saxitoxin (STX), a principal phycotoxin contributing to paralytic shellfish poisoning, is largely produced by marine microalgae of the genus Alexandrium. This toxin affects a wide range of species, inducing massive deaths in fish and other marine species. However, marine bivalves can resist and accumulate paralytic shellfish poisons. Despite numerous studies on the impact of STX in marine bivalves, knowledge regarding STX recognition at molecular level by benthic species remains scarce. Therefore, the aim of this study was to identify novel genes that interact with STX in the Chilean mussel Mytilus chilensis...

While we are approaching the global eradication of circulating wild-type polioviruses(PV), vaccination with oral poliovirus vaccine (OPV) has led to emergence of circulating vaccine-derived poliovirus (cVDPV) and vaccine-associated paralytic poliomyelitis (VAPP). Complete cessation of all poliovirus infections may require stopping use of OPV and formulating improved vaccines and new antiviral drugs. Currently, no licensed drugs are available to treat chronically infected poliovirus excretors. Here, we created a modified PV expressing Gaussia Luciferase (PV-GLuc) and developed a cell-based high-throughput screening (HTS) antiviral assay...

Rabies is a zoonotic disease that is usually transmitted to humans by animal bites. Dogs are the most important vector worldwide. There are encephalitic and paralytic forms of the disease. There are differences in the clinical features of the disease acquired from dogs and bats. Neuroimaging is non-specific. Confirmatory diagnostic laboratory tests for rabies include detection of neutralizing anti-rabies virus antibodies in serum or cerebrospinal fluid and rabies virus antigen or RNA in tissues or fluids. Rabies is preventable after recognized exposures with wound cleansing and administration of rabies vaccine and rabies immune globulin...

Inshore and offshore waters of the Gulf of Maine (USA) have spring/summer harmful algal blooms (HABs) of the toxic dinoflagellate Alexandrium fundyense, which is responsible for paralytic shellfish poisoning (PSP) in humans. The calanoid copepod Calanus finmarchicus co-occurs with A. fundyense during the seasonal blooms. At that time, C. finmarchicus population abundances are high, dominated by immature copepods preparing for diapause, and by actively-reproducing adults. High survival has been reported for copepods exposed to toxic A...

BACKGROUND: Drug overdose is the leading cause of injury-related fatality in the United States, and respiratory failure remains a major source of morbidity and mortality. OBJECTIVES: We aimed to identify the incidence and risk factors for endotracheal intubation after acute drug overdose. METHODS: This secondary data analysis was performed on a 5-year prospective cohort at two urban tertiary-care hospitals. The present study analyzed adult patients with suspected acute drug overdose to derive independent clinical predictors of endotracheal intubation...

Saxitoxin (STX) and its analogs, the paralytic shellfish toxins (PSTs), are a group of potent neurotoxins well known for their role in acute paralytic poisoning by preventing the generation of action potentials in neuronal cells. They are found in both marine and freshwater environments globally and although acute exposure from the former has previously received more attention, low dose extended exposure from both sources is possible and to date has not been investigated. Given the known role of cellular electrical activity in neurodevelopment this pattern of exposure may be a significant public health concern...

BACKGROUND: Acute esophageal necrosis or Gurvits syndrome is a rare clinical condition characterized by necrotic esophageal mucosa with an abrupt end at the gastroesophageal junction. Its etiology is multifactorial, but mainly related to low-flow states. We describe a case in which a patient accidentally took the wrong medication, with clozapine and olanzapine most probably being the cause of his subsequent acute esophageal necrosis. This situation is, to the best of our knowledge, unprecedented in the medical literature...

The term Guillain-Barré syndrome (GBS), the most frequent cause of acute paralytic neuropathy, covers a number of recognisably distinct variants. The exact cause of GBS is unknown, but 50-70% of cases appear 1-2weeks after a respiratory or gastrointestinal infection, or another immune stimulus that induces an aberrant autoimmune response targeting peripheral nerves and their spinal roots. The interplay between the microbial and host factors that dictate whether and how the immune response shifts towards autoreactivity is still unclear, and nothing is known about the genetic and environmental factors that affect an individual's susceptibility to the disease...

Harmful Algal Bloom species are ubiquitous and their blooms occur in the Arabian Gulf. In this study, two cruises were performed in 2012 and 2013 to collect phytoplankton samples from 4 sites in the Arabian Gulf. Toxin analyses of phytoplankton samples for 32 algal toxins from 5 different toxin groups were conducted on the samples using both enzyme linked immunosorbent assay (ELISA) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Results demonstrated, for the first time, the presence of paralytic shellfish toxins (PSTs), diarrhetic shellfish toxin (DST), amnesic shellfish toxin (AST), cyclic imines (CIs) and polyether-lactone toxins in freeze-dried phytoplankton samples...
