Contemporary neurosciences have grown beyond the limits of a natural science. To its most vocal advocates, the study of the human brain can provide nothing short of the basis for a new science of man-the link between the "natural" and "human" sciences-as a simple consequence of the growing mass of facts relating to this most marvelous organ, accumulated in the last four decades. This straightforward picture of the growing import of the neurosciences simplifies and obscures the myriad different interpretations and images of "the brain" that have inspired the development of the neurosciences...

Ontogenetic changes in venom composition have important ecological implications due the relevance of venom in prey acquisition and defense. Additionally, intraspecific venom variation has direct medical consequences for the treatment of snakebite. However, ontogenetic changes are not well documented in most species. The Mexican Black-tailed Rattlesnake ( Crotalus molossus nigrescens ) is large-bodied and broadly distributed in Mexico. To document venom variation and test for ontogenetic changes in venom composition, we obtained venom samples from twenty-seven C...

Powerful tools for functional studies in emerging model systems are beginning to yield fresh insights into the inner workings of cells because of newly available tools for functional studies. Recent work leveraging a hydrozoan jellyfish to study light-mediated gamete maturation has uncovered a multifunctional cell type and the associated regulatory machinery, with implications for understanding the evolution of reproduction.

OBJECTIVE: To compare the incidence of hypersensitivity reactions following copperhead envenomation treated with Fab antivenom (FabAV) or placebo. METHODS: Patients with copperhead snakebites received treatment and follow-up in a prospective, randomized, double-blind, placebo-controlled trial of FabAV or placebo. The treatment allocation ratio was 2:1 (FabAV:placebo). All of the included patients received at least one dose of study treatment. We reviewed all treatment-emergent adverse events (AEs) using a previously published scale to classify likely hypersensitivity reactions as mild, moderate, or severe...

We present the genome of the moon jellyfish Aurelia, a genome from a cnidarian with a medusa life stage. Our analyses suggest that gene gain and loss in Aurelia is comparable to what has been found in its morphologically simpler relatives-the anthozoan corals and sea anemones. RNA sequencing analysis does not support the hypothesis that taxonomically restricted (orphan) genes play an oversized role in the development of the medusa stage. Instead, genes broadly conserved across animals and eukaryotes play comparable roles throughout the life cycle...

Envenomation of cockroach cerebral ganglia by the parasitoid Jewel wasp, Ampulex compressa, induces specific, long-lasting behavioural changes. We hypothesized that this prolonged action results from venom-induced changes in brain neurochemistry. Here, we address this issue by first identifying molecular targets of the venom, i.e., proteins to which venom components bind and interact with to mediate altered behaviour. Our results show that venom components bind to synaptic proteins and likely interfere with both pre- and postsynaptic processes...

Taiwan is an island located in the south Pacific, a subtropical region that is home to 61 species of snakes. Of these snakes, four species-Trimeresurus stejnegeri, Protobothrops mucrosquamatus, Bungarus multicinctus and Naja atra-account for more than 90% of clinical envenomation cases. Currently, there are two types of bivalent antivenom: hemorrhagic antivenom against the venom of T. stejnegeri and P. mucrosquamatus, and neurotoxic antivenom for treatment of envenomation by B. multicinctus and N. atra. However, no suitable detection kits are available to precisely guide physicians in the use of antivenoms...

Echis carinatus envenomation leads to severe tissue necrosis at the bitten site by releasing DNA from immune cells that blocks the blood flow. An earlier report has shown that exogenous DNase 1 offers protection against such severe local tissue necrosis. Tricosanthus tricuspidata is a medicinal plant and the paste prepared from its leaves has been used extensively for the treatment of snakebite-induced tissue necrosis. Most studies including reports from our laboratory focused on plant secondary metabolite as therapeutic molecules against snakebite envenomation...

BACKGROUND: Priapism has been linked to many commonly prescribed medications, as well as recreational drugs and toxins. Although the incidence of priapism as a result of medication is small, the increasing use of antidepressants, antipsychotics, and recreational drugs may lead to more cases of pharmacologically-induced priapism in the future. AIM: To provide a comprehensive, up-to-date review of the most common causes of pharmacologically induced priapism and discuss incidence, pathophysiology, and basic management strategies...

Due to their potent coagulotoxicity, Australian elapid venoms are unique relative to non-Australian members of the Elapidae snake family. The majority of Australian elapids possess potent procoagulant venom, while only a few species have been identified as possessing anticoagulant venoms. The majority of research to-date has concentrated on large species with range distributions overlapping major city centres, such as brown snakes (Pseudonaja spp.) and taipans (Oxyuranus spp.). We investigated the venom from the poorly studied genus Denisonia and documented anticoagulant activities that were differentially potent on amphibian, avian, and human plasmas...

The Magnaporthe oryzae avirulence gene AvrPib is required for the resistance mediated by its cognate resistance (R) gene Pib which has been intensively used in indica rice breeding programs in many Asian countries. However, the sequence diversity of AvrPib among geographically distinct M. oryzae populations was recently shown to be increasing. Here we selected a field population consisting of 248 rice blast isolates collected from a disease hotspot in Philippine for the analysis of AvrPib haplotypes and their pathogenicity against Pib...

Background: Lachesis muta rhombeata (Lmr) is the largest venomous snake in Latin America and its venom contains mainly enzymatic components, such as serine and metalloproteases, L-amino acid oxidase and phospholipases A2 . Metalloproteases comprise a large group of zinc-dependent proteases that cleave basement membrane components such as fibronectin, laminin and collagen type IV. These enzymes are responsible for local and systemic changes, including haemorrhage, myonecrosis and inflammation...

Lionfish ( Pterois volitans ) are an invasive species originally from the Indian and Pacific oceans and the Red Sea that now are found all along the southeastern coast of the United States. Prompt and comprehensive treatment provides benefit to the patient. As lionfish numbers continue to increase, physicians across multiple specialties and regions may see an increase in envenomation injuries. It is important that physicians are aware of how to recognize and treat lionfish stings.

INTRODUCTION: Arizona has the highest incidence of scorpion envenomation reported to US poison control centers (PCCs). Most cases reported are from a residence, but specific details are limited. METHODS: Specialists at Arizona's two PCCs prospectively completed the Factors of Envenomation in Arizona Residences Survey (FEARS) for residential scorpion exposures reported during 4-week periods in the summer and winter. Based on these results, a second questionnaire, FEARS-2, targeting indoor residential exposures was then administered...

Molecular chaperones promote the correct folding of proteins in aggregation-prone cellular environments by stabilizing nascent polypeptide chains and providing appropriate folding conditions. Prefoldins (PFDs) are molecular chaperones found in archaea and eukaryotes, generally characterized by a unique jellyfish-like hexameric structure consisting of a rigid beta-barrel backbone with protruding flexible coiled-coils. Unlike eukaryotic PFDs that mainly interact with cytoskeletal components, archaeal PFDs can stabilize a wide range of substrates; such versatility reflects PFD's role as a key element in archaeal chaperone systems, which often lack general nascent-chain binding chaperone components such as Hsp70...

Animal studies demonstrate that hyperactive neurons facilitate early accumulation and spread of tau and amyloid-β proteins in the pathological cascade of Alzheimer's disease (AD). Human neuroimaging studies have linked hippocampal hyperactivity to amyloid-β accumulation, apolipoprotein ε4 (APOE4) and clinical progression from prodromal AD to clinical dementia. The relationship between hippocampal hyperactivity and early AD molecular pathology (amyloid-β and tau accumulation) prior to clinical symptoms remains to be elucidated...

The scyphozoan jellyfish Cyanea capillata and Nemopilema nomurai are common blooming species in China. They possess heterogeneous nematocysts and produce various types of venom that can elicit diverse sting symptoms in humans. However, the differences in venom composition between the two species remain unclear. In this study, a combined transcriptomic and proteomic approach was used to identify and compare putative toxins in penetrant nematocysts isolated from C. capillata and N. nomurai. A total of 53 and 69 putative toxins were identified in C...
