Chinese patent medicine containing aconitine is the key in clinical rational drug use. These drugs contain Chuanwu, Caowu or Fuzi, and Aconitum brachypodum with functions of expelling wind-dampness or tonifying Yang, all of which shall be used by strictly following the indications and dosage. However, there are many kinds of such drugs. Not only the unfamiliar knowledge of some Chinese and Western physicians about the characteristics of them, but also the combination of multiple drugs from different clinical departments, would increase the risk of aconitine poisoning...

Symbionts (e.g., endoparasites and commensals) play an integral role in their host's ecology, yet in many cases their diversity is likely underestimated. Although endoparasites are traditionally characterized using morphology, sequences of conserved genes, and shotgun metagenomics, host transcriptomes constitute an underused resource to identify these organisms' diversity. By isolating non-host transcripts from host transcriptomes, individual host tissues can now simultaneously reveal their endoparasite species richness (i...

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...

We report a 24year old female who presented with sudden and severe headaches after recent carbon monoxide poisoning. Imaging revealed an acute cerebral venous thrombosis. Prior studies have suggested that carbon monoxide is a risk factor for an acute hypercoagulable state (i.e. DVT). However, little data is available regarding the correlation between carbon monoxide poisoning and cerebral venous thrombosis. This case demonstrates that such a correlation should be considered in acute intracerebral thrombotic events...

Emergencies due to snakebites, although unusual in Spain, are potentially serious. Of the 13 species native to the Iberian peninsula, only 5 are poisonous: 2 belong to the Colubridae family and 3 to the Viperidae family. Bites from these venemous snakes can be life-threatening, but the venomous species can be easily identified by attending to certain physical traits. Signs denoting poisoning from vipers, and the appropriate treatment to follow, have changed in recent years.

Consumption of fast food and street food is increasingly common among Vietnamese, particularly in large cities. The high daily demand for these convenient food services, together with a poor management system, has raised concerns about food hygiene and safety (FHS). This study aimed to examine the FHS knowledge and practices of food processors and sellers in food facilities in Hanoi, Vietnam, and to identify their associated factors. A cross-sectional study was conducted with 1,760 food processors and sellers in restaurants, fast food stores, food stalls, and street vendors in Hanoi in 2015...

Staphylococcus aureus is a potential pathogen contaminating raw milk and dairy products, where it is able to produce thermostable enterotoxins that can cause staphylococcal food poisoning. This study was undertaken to investigate the inhibitory activity of a Lactococcus lactis strain (isolated from milk) on S. aureus growth and staphylococcal enterotoxin A (SEA) production. In the presence of L. lactis , the number of the pathogen decreased significantly (p<0.05) after 6 h of incubation in a laboratory medium and milk (3 log CFU/mL reduction compared to pure cultures)...

Imidazopyrazinones (IPYs) are a new class of compounds that target bacterial topoisomerases as a basis for their antibacterial activity. We have characterized the mechanism of these compounds through structural/mechanistic studies showing they bind and stabilize a cleavage complex between DNA gyrase and DNA ('poisoning') in an analogous fashion to fluoroquinolones, but without the requirement for the water-metal-ion bridge. Biochemical experiments and structural studies of cleavage complexes of IPYs compared with an uncleaved gyrase-DNA complex, reveal conformational transitions coupled to DNA cleavage at the DNA gate...

It is conservatively estimated that 5,000 deaths per year and 20,000 injuries in the USA are due to poisonings caused by chemical exposures (e.g., carbon monoxide, cyanide, hydrogen sulfide, phosphides) that are cellular inhibitors. These chemical agents result in mitochondrial inhibition resulting in cardiac arrest and/or shock. These cellular inhibitors have multi-organ effects, but cardiovascular collapse is the primary cause of death marked by hypotension, lactic acidosis, and cardiac arrest. The mitochondria play a central role in cellular metabolism where oxygen consumption through the electron transport system is tightly coupled to ATP production and regulated by metabolic demands...

Spatial heterogeneity in the strength or agents of selection can lead to geographic variation in ecologically important phenotypes. Many dendrobatid frogs sequester alkaloid toxins from their diets and often exhibit fixed mutations at NaV1.4, a voltage-gated sodium ion channel associated with alkaloid toxin resistance. Yet previous studies have noted an absence of resistance mutations in individuals from several species known to sequester alkaloid toxins, suggesting possible intraspecific variation for alkaloid resistance in these species...

Lead toxicity is an important environmental disease and its effects on the human body can be devastating. Unique exposures to Special Operations Forces personnel may include use of firing ranges, use of automotive fuels, production of ammunition, and bodily retention of bullets. Toxicity may degrade physical and psychological fitness, and cause long-term negative health outcomes. Specific effects on fine motor movements, reaction times, and global function could negatively affect shooting skills and decision-making...

Treatments of patient with amlodipine (a calcium channel blocker, CCB) overdose/poisoning remain challenging and death is certain if not intervened timely. Furthermore, for a society, the availability and common use of this drug make more vulnerable, especially by children, towards an accidental/suicidal poisoning. Here we describe an adolescent school girl who took 150 mg of amlodipine and was admitted in our hospital approximately 4 hours after ingestion with suicidal intention. She developed circulatory failure and tachypnea...
