Problems of toxicants in marine food products
Bagnis, Berglund, Elias, van Esch, Halstead, Kojima
Bull World Health Organ 1970;42(1):69-88. Abstract
The expansion of marine fisheries into tropical waters, which is now occurring, will increase the risks of widespread poisonings because of the abundance of biotoxins in warm-water organisms. However, toxic marine organisms are not only a health hazard but also a possible source of new pharmaceutical products. [Pubmed: 4908418] | | 2. |

Distribution and ecology of Bulinus truncatus in Khuzestan, Iran*
Chu, Massoud, Arfaa
Bull World Health Organ 1968;39(4):607-637. Abstract
The results of a 5-year study on the distribution and ecology of Bulinus truncatus in Khuzestan, south-western Iran, are described. Live snails were found in 4 foci, namely, the main focus, the upper Karun River, the lower Karkheh River, and the Bala Rud watershed; in addition, dead snails were found in 3 other foci. The patchy distribution of snails was related to the presence of surface waters and to their chemical composition. [Pubmed: 5304436] | | 3. |

Evaluating mercury biomagnification in fish from a tropical marine environment using stable isotopes (delta13C and delta15N).
Al-Reasi HA, Ababneh FA, Lean DR
Environ. Toxicol. Chem. 2007 Aug;26(8):1572-81. Abstract
Concentrations of total mercury (T-Hg) and methylmercury (MeHg) were measured in zooplankton and 13 fish species from a coastal food web of the Gulf of Oman, an arm of the Arabian Sea between Oman and Iran. Stable isotope ratios (delta13C and delta15N) also were determined to track mercury biomagnification. The average concentration of T-Hg in zooplankton was 21 +/- 8.0 ng g(-1) with MeHg accounting 10% of T-Hg. Total mercury levels in fish species ranged from 3.0 ng g(-1) (Sardinella longiceps) to 760 ng g(-1) (Rhizoprionodon acutus) with relatively lower fraction of MeHg (72%) than that found in other studies. The average trophic difference (Deltadelta13C) between zooplankton and planktivorous fish (Selar crumenopthalmus, Rastrelliger kanagurta, and S. longiceps) was higher (3.4 per thousandth) than expected, suggesting that zooplankton may not be the main diet or direct carbon source for these fish species. However, further sampling would be required to compensate for temporal changes in zooplankton and the influence of their lipid content. Trophic position inferred by delta15N and and slopes of the regression equations (log10[T-Hg] = 0.13[delta15N] - 3.57 and log10[MeHg] = 0.14[delta15N] - 3.90) as estimates of biomagnification indicate that biomagnification of T-Hg and MeHg was lower in this tropical ocean compared to what has been observed in arctic and temperate ecosystems and tropical African lakes. The calculated daily intake of methylmercury in the diet of local people through fish consumption was well below the established World Health Organization (WHO) tolerable daily intake threshold for most of the fish species except Euthynnus affinis, Epinephelus epistictus, R. acutus, and Thunnus tonggol, illustrating safe consumption of the commonly consumed fish species.

When two equals three: developmental osteology and homology of the caudal skeleton in carangid fishes (Perciformes: Carangidae).
Hilton EJ, Johnson GD
Evol. Dev.;9(2):178-89. Abstract
Ontogeny often provides the most compelling evidence for primary homology in evolutionary developmental studies and is critical to interpreting complex structures in a phylogenetic context. As an example of this, we document the ontogenetic development of the caudal skeleton of Caranx crysos by examining a series of cleared and stained larval and postlarval specimens. By studying ontogeny, we are able to more accurately identify some elements of the adult caudal skeleton than is possible when studying the adult stage alone. The presence of two epurals has been used as a synapomorphy of Caranginae (homoplastically present in the scomberoidine genera Scomberoides and Oligoplites). Here we find that three epurals (ep) are present in larvae and small postlarval juveniles (i.e.,<25 mm standard length [SL]) of C. crysos and other carangines, but ep2 never ossifies and does not develop beyond its initial presence. Ep2 was last observed in a 33.6 mm SL specimen as a small nodule of very lightly stained cartilage cells and eventually disappears completely. Therefore, the two epurals present in the adult are ep1 and ep3. In other carangines examined (e.g., Selene, Selar), the rudimentary ep2 ossifies and appears to fuse to the proximal tip of ep1. In these taxa, therefore, the two epurals of the adult appear to be ep1+2 and ep3. We found no indication of three epurals at any stage in the development of Oligoplites (developmental material of Scomberoides was unavailable). We discuss the osteology of the caudal skeleton of carangoid fishes generally and emphasize the power and importance of ontogeny in the identification of primary homology. [Pubmed: 17371400] | | 5. |

A new species of Henneguya (Myxozoa) in the big-eyed scad (Selar crumenophthalmus) from Hawaii.
Work TM, Takata G, Whipps CM, Kent ML
J. Parasitol. 2008 Apr;94(2):524-9. Abstract
We describe a new myxozoan, Henneguya akule n. sp., infecting the carangid fish Selar crumenophthalmus in Hawaii. Spores were found only in the aortic bulb, characterized by elliptical capsule with 2 tails, and pyriform polar capsules that angled toward the anterior end of the spore. Polar filaments had 3-4 coils. Parasites were present in apparently healthy fishes and caused no evident gross pathology. On microscopy, parasites evinced a mild inflammatory response in the host characterized by accumulations of eosinophilic fibrillar material around spores and a mononuclear infiltrate in the adventitia of the bulbus arteriosus. Overall prevalence was 20%, and prevalence between 2001 and 2006 ranged from 12 to 27%, but did not differ significantly between years. In contrast, prevalence of infection was highest in south-central Oahu. There was no relationship between infection status and body condition or gender of fish, and infection was absent in the smallest and largest fishes. Phylogenetically, H. akule n. sp. is most closely related to other Henneguya species infecting the heart of marine fishes based on ribosomal DNA analysis. This is the first documentation of a myxozoan parasite in marine fishes from Hawaii. [Pubmed: 18564755] | | 6. |

A new monorchiid trematode, Paramonorcheides selaris n. sp., from the carangid fish Selar crumenophthalmus in the Bay of Bengal off the Visakhapatnam coast of India.
Triveni Lakshmi T, Madhavi R
Syst. Parasitol. 2009 Jun;73(2):135-9. Epub 2009 May 08. Abstract
Paramonorcheides selaris n. sp. is described from the intestine of the carangid fish Selar crumenophthalmus (Bloch) off the Visakhapatnam coast, Bay of Bengal. It is closest to the Australian species P. pseudocaranxi Dove & Cribb, 1998, but differs in its shorter cirrus-sac extending only to the level of the ovary rather than to the level of the testes, in lacking eye-spot pigment and in details of the armature of the terminal genitalia. P. pseudocaranxi of Machida (2005) is regarded as identical to the new species. The validity of Allobacciger Hafeezullah & Siddiqi, 1970, as distinct from Monorcheides Odhner, 1905, is discussed. A key to the six species of Paramonorcheides Yamaguti, 1938 is presented. [Pubmed: 19424791] | | 9. |

A multiarray electrode mapping method for percutaneous thermocoagulation as treatment of trigeminal neuralgia. Technical note on a series of 178 consecutive procedures.
Karol EA, Karol MN
Surg Neurol. 2009 Jan;71(1):11-7; discussion 17-8. Epub 2008 Mar 06. Abstract
BACKGROUND: We describe our method and mapping technique of the trigeminal nerve using a quadripolar electrode to minimize morbidity of percutaneous thermocoagulation as treatment of trigeminal neuralgia. METHOD: Of 381 patients selected for postgasserian thermocoagulation, 178 consecutive procedures were carried out using, in most cases, our painless and ambulatory method and technique. All patients were preoperatively subjected to 3-dimensional constructive interference in steady-state magnetic resonance and magnetic resonance angiography. Transgasserian introduction of our quadripolar multiarray electrode under constant fluoroscopic monitoring is used with systematic recording of radiologic angles at, in front of, and behind the clivus profile, always below the selar floor. The individual's somatotopic map based on the verbal responses of 34 facial subsegments in lieu of the usual 3 is carefully established. Lesions are aimed at the trigger of pain and restricted to fibers with the lowest thresholds. Maximal lesions are one third the size used in conventional thermocoagulation. Lesions attempt to avoid damage to the first division, uninvolved fibers, and the motor division. RESULTS: Pre- and postoperatory thresholds demonstrate that trigger-aimed small lesions do not extend to unwanted subsegments. The described technique can minimize unnecessary complications from percutaneous thermocoagulation. [Pubmed: 18328544] | | 10. |

Williams, Carpenter, Van Tassell, Hoetjes, Toller, Etnoyer, Smith
PLoS One 2010 May 21;5(5). published online before print Abstract
Biodiversity surveys were conducted on Saba Bank, Netherlands Antilles, to assess ichthyofaunal richness and to compare with published surveys of other Caribbean localities. The primary objective was to estimate the total species richness of the Saba Bank ichthyofauna. A variety of sampling techniques was utilized to survey the fish species of both the visually accessible megafauna and the camouflaged and small-sized species comprising the cryptic ichthyofauna.

Imada, Hoki, Suehiro, Okuyama, Kurabayashi, Shimada, Naruse, Takeda, Kubo, Takeuchi
PLoS One 2010 Jun 22;5(6). published online before print Abstract
In animal groups such as herds, schools, and flocks, a certain distance is maintained between adjacent individuals, allowing them to move as a cohesive unit. Proximate causations of the cohesive and coordinated movement under dynamic conditions, however, have been poorly understood. [Pubmed: 20582314] | | 12. |

Molecular phylogeny of the acanthocephala (class palaeacanthocephala) with a paraphyletic assemblage of the orders polymorphida and echinorhynchida.
Verweyen L, Klimpel S, Palm HW
PLoS ONE. 2011;6(12):e28285. Epub 2011 Dec 05. Abstract
Acanthocephalans are attractive candidates as model organisms for studying the ecology and co-evolutionary history of parasitic life cycles in the marine ecosystem. Adding to earlier molecular analyses of this taxon, a total of 36 acanthocephalans belonging to the classes Archiacanthocephala (3 species), Eoacanthocephala (3 species), Palaeacanthocephala (29 species), Polyacanthocephala (1 species) and Rotifera as outgroup (3 species) were analyzed by using Bayesian Inference and Maximum Likelihood analyses of nuclear 18S rDNA sequence. This data set included three re-collected and six newly collected taxa, Bolbosoma vasculosum from Lepturacanthus savala, Filisoma rizalinum from Scatophagus argus, Rhadinorhynchus pristis from Gempylus serpens, R. lintoni from Selar crumenophthalmus, Serrasentis sagittifer from Johnius coitor, and Southwellina hispida from Epinephelus coioides, representing 5 new host and 3 new locality records. The resulting trees suggest a paraphyletic arrangement of the Echinorhynchida and Polymorphida inside the Palaeacanthocephala. This questions the placement of the genera Serrasentis and Gorgorhynchoides within the Echinorhynchida and not the Polymorphida, necessitating further insights into the systematic position of these taxa based on morphology.

Bitemporal compression injury to the head
Lateef
J Emerg Trauma Shock 2011;4(3):411-412. Abstract
Most cranio-cerebral injuries seen in the emergency department are caused by acceleration-deceleration or a direct impact mechanism. Compression or crush injury to the head is less commonly seen. A crush injury occurs when a body part is subjected a degree of force or pressure, usually after being trapped between two heavy objects or hard surfaces. We describe here a case of accidental bitemporal and facial compression injury in a young lady. [Pubmed: 21887036] | | 16. |

Quantifying the Interplay between Environmental and Social Effects on Aggregated-Fish Dynamics
Capello, Soria, Cotel, Deneubourg, Dagorn
PLoS One 2011 Dec 12;6(12). published online before print Abstract
Demonstrating and quantifying the respective roles of social interactions and external stimuli governing fish dynamics is key to understanding fish spatial distribution. If seminal studies have contributed to our understanding of fish spatial organization in schools, little experimental information is available on fish in their natural environment, where aggregations often occur in the presence of spatial heterogeneities. Here, we applied novel modeling approaches coupled to accurate acoustic tracking for studying the dynamics of a group of gregarious fish in a heterogeneous environment. To this purpose, we acoustically tracked with submeter resolution the positions of twelve small pelagic fish (Selar crumenophthalmus) in the presence of an anchored floating object, constituting a point of attraction for several fish species. We constructed a field-based model for aggregated-fish dynamics, deriving effective interactions for both social and external stimuli from experiments. We tuned the model parameters that best fit the experimental data and quantified the importance of social interactions in the aggregation, providing an explanation for the spatial structure of fish aggregations found around floating objects. Our results can be generalized to other gregarious species and contexts as long as it is possible to observe the fine-scale movements of a subset of individuals. [Pubmed: 22174770] | | 17. |

[Optic nerve gliomas: a study of 11 cases].
Torres LF, Medeiros BC, Noronha L, Pedroso A, Ramina R
Arq Neuropsiquiatr. 1996 Jun;54(2):280-3. Abstract
Optic nerve gliomas may occur alone or as components of neurofibromatosis. They are rare tumors accounting for 2 to 5% of all intracranial tumors and 6% of the intra-orbitary neoplasms. The authors present 11 cases of optic nerve-glioma diagnosed in Curitiba in the last 25 years. Out of these 11 patients there were 10 women and only 1 man. The ages ranged from 3 to 25 years old, and 6 patients were under 15 years. In this series, 27.3% (n = 3) of the cases were associated with neurofibromatosis. Five patients had their tumors restricted to the optic nerve while the others had either extension to the optic chiasm, supra-selar region, frontal or temporal lobe. All the patients had pilocytic astrocytomas. [Pubmed: 8984986] | | 18. |

Overexpression Beadex mutations and loss-of-function heldup-a mutations in Drosophila affect the 3' regulatory and coding components, respectively, of the Dlmo gene.
Shoresh, Orgad, Shmueli, Werczberger, Gelbaum, Abiri, Segal
Genetics 1998 Sep;150(1):283-299. Abstract
LIM domains function as bridging modules between different members of multiprotein complexes. We report the cloning of a LIM-containing gene from Drosophila, termed Dlmo, which is highly homologous to the vertebrate LIM-only (LMO) genes. The 3' untranslated (UTR) of Dlmo contains multiple motifs implicated in negative post-transcriptional regulation, including AT-rich elements and Brd-like boxes. Dlmo resides in polytene band 17C1-2, where Beadex (Bx) and heldup-a (hdp-a) mutations map. We demonstrate that Bx mutations disrupt the 3'UTR of Dlmo, and thereby abrogate the putative negative control elements. This results in overexpression of Dlmo, which causes the wing scalloping that is typical of Bx mutants. We show that the erect wing phenotype of hdp-a results from disruption of the coding region of Dlmo. This provides molecular grounds for the suppression of the Bx phenotype by hdp-a mutations. Finally, we demonstrate phenotypic interaction between the LMO gene Dlmo, the LIM homeodomain gene apterous, and the Chip gene, which encodes a homolog of the vertebrate LIM-interacting protein NLI/Ldb1. We propose that in analogy to their vertebrate counterparts, these proteins form a DNA-binding complex that regulates wing development. [Pubmed: 9725847] |
