We have investigated the co-involvement of endogenous NGF and impulses in collateral sprouting cutaneous sensory nerves adult rats, specifically A delta-axons involved mechanonociception C-fibers that mediate heat nociception. Their was measured by progressive expansion, respectively, behaviorally defined "pinch" "heat" fields into surrounding denervated skin (the light-touch alpha-fibers do not sprout mammals). The expansions such "isolated" were totally prevented animals injected daily...
A key role has not yet been identified for beta nerve growth factor (NGF) in the responses that continue to be expressed sensory neurons of adult animals. We have now examined effects daily administration rats (and a few experiments, mice) antiserum NGF on (i) collateral sprouting undamaged nociceptive nerves occurs into denervated adjacent skin and (ii) regeneration cutaneous axons after they are damaged. The results were unexpected. All was prevented already progress halted; resumed when...
Ciguatera is a type of food poisoning that results from eating certain tropical fish which have become toxic. It common in Australia: 175 outbreaks, involved 527 people, were reported Queensland between 1965 and 1984. seems restricted to areas around the Australian coastline. Most reports narrow-barred Spanish mackerel, Scomberomorus commersoni, most caught southern waters. Up 2100 cases may occurred north 1984, not recorded by writers. The symptoms ciguatera Australia are similar those...
ABSTRACT Manzamine A, a β-carboline alkaloid present in several marine sponge species, inhibits the growth of rodent malaria parasite Plasmodium berghei vivo. More than 90% asexual erythrocytic stages P. were inhibited after single intraperitoneal injection manzamine A into infected mice. remarkable aspect treatment is its ability to prolong survival highly parasitemic mice, with 40% recovery 60 days injection. Oral administration an oil suspension also produced significant reductions...

DOI: 10.2216/07-15.1Gambierdiscus species produce toxins that cause ciguatera fish poisoning (CFP), the most common nonbacterial illness associated with consumption worldwide. Understanding role individual play in causing CFP...
Abstract Eusociality has convergently evolved multiple times, but the genomic basis of caste-based division labor and degree to which independent origins eusociality have utilized common genes remain largely unknown. Here we characterize caste-specific transcriptomic profiles across development adult body segments from pharaoh ants ( Monomorium pharaonis ) honey bees Apis mellifera ), representing two eusociality. We identify a substantial shared core upregulated in abdomens queen that also...
Ciguatera fish poisoning (CFP) is a serious health problem in tropical regions and caused by the bioaccumulation of lipophilic toxins produced dinoflagellates genus Gambierdiscus. Gambierdiscus species are morphologically similar difficult to distinguish from one another even when using scanning electron microscopy. Improved identification detection methods that sensitive rapid needed identify toxic investigate potential distribution abundance patterns relation incidences CFP. This study...
A new, toxin‐producing, benthic dinoflagellate named Gambierdiscus yasumotoi sp. nov. was isolated from macroalgae the fringing coral reef surrounding Singapore island of Pulau Hantu. The plate formula G. is P o , 3′, 7", 6c, 6s, 5"′, and 2"". has a globular shape not anterior‐posteriorly compressed as are two other known species in this genus, toxicus Adachi et Fukuyo 1979 belizeanus Faust 1995. girdle descends one to widths without overhang contrast ascending girdles belizeanus. dimensions...
Abstract Several competition indices are evaluated to determine their relationship with annual diameter growth in mixed species northern hardwood stands upper Michigan. Indices on four different shade tolerance. A new index which incorporates factors representing both root and crown is formulated tested. Simple size ratio perform as well or better correlation than growing space, area overlap, root/crown indices. Hegyi's several forms of the show most consistent performance across study...
Abstract Three strains of cultured Gambierdiscus toxicus yielded distinct maitotoxins (maitotoxin‐1, ‐2, and ‐3) which were purified to homogeneity by high pressure liquid chromatography. Maitotoxins‐1 ‐2 are large toxins (molecular weights for the sodium salts = 3,422 3,298, respectively), whereas maito‐toxin‐3 is relatively small weight 1,060 salt). The contractile actions on isolated guinea‐pig left atria, vas deferens ilea maitotoxins‐1 compared with those maitotoxin, maitotoxin‐3....
Abstract Coolia monotis is a benthic dinoflagellate previously thought to be non‐toxic. We describe new toxin, named cooliatoxin, purified from cultures of strain C. isolated Australia. Cooliatoxin likely mono‐sulphated, polyether toxin (Mr = 1,062; i.p. LD 50 1 mg/kg in mice) that induces hypothermia and respiratory failure mice after pronounced delay period during which there are no obvious signs intoxication. These similar those reported for the shellfish yessotoxin molecular weight...
Abstract There have been many individual phytoplankton datasets collected across Australia since the mid 1900s, but most are unavailable to research community. We searched archives, contacted researchers, and scanned primary grey literature collate 3,621,847 records of marine species from Australian waters 1844 present. Many these small for local questions, combined they provide over 170 years data on communities in waters. Units taxonomy standardised, obviously erroneous removed, all...
