cell-free synthesis of fish preproinsulin, and processing by heterologous mammalian microsomal membranes.poly(a)-containing mrna isolated from the islets of langerhans obtained from two species of fish, angler fish (lophius americanus) and sea raven (hemitripterus americanus), stimulated protein synthesis 16-fold in a wheat germ cell-free system. characterization of the translation products by polyacrylamide gel electrophoresis in sodium dodecyl sulfate showed a major polypeptide weighing 11,500 daltons that was specifically precipitated by an antibody against angler fish insulin. partial sequence ...1977325565
[proteolytic events in the maturation of pro-neuropeptides. the somatostatin model].the post-translational processing (maturation) of the precursors was studied on the model of the prosomatostatin. we have shown the presence of a single and common precursor to both somatostatin -28 and -14 in mouse hypothalamus, in contrast with the situation in the teleostean fish, lophius piscatorius. the search for a maturation activity was carried out using a synthetic undecapeptide substrate including in its sequence the cleavage site for somatostatin-14 release. using this peptide, we cha ...19862876674
the ultrastructure of spores (protozoa: microsporida) from lophius americanus, the angler fish.spinal and cranial ganglia of american angler fish, lophius americanus, are often infected with microsporidia. this protozoon elicits the formation of large, spore-filled, hypertrophied host cells, cysts. previous reports of microsporidia in european lophiids identify the parasite as spraguea lophii, a genus which has recently been shown to be dimorphic. the spores from l. americanus are monomorphic (2.8 x 1.5 micron) and uninucleate. each spore contains a polar tube that forms six to nine coils ...19863795144
[inhalation allergy to fly larva. a clinical case].the authors describe a clinical case of rhinitis and asthma in an angler after exposure to antigenic material released from larvae of fly, commonly used by anglers as bait. the common names of these larvae are "blue bottle", "green bottle" and "grey bottle". the patient was usually in good health, free from allergic diseases and free from asthmatic attacks when far from exposure to the baits. spirometric evaluation revealed a fall of 21% in vems after challenge with antigen. skin test (prick) wi ...19873449104
autonomic innervation and photosensitivity of the sphincter pupillae muscle of two teleosts: lophius piscatorius and opsanus tau.the irises of both lophius piscatorius (goosefish) and opsanus tau (toadfish), like those of many other vertebrates, have a photosensitive sphincter pupillae that responds autonomously to light. the iris also constricts when exposed to either cholinergic or adrenergic agonists. our data suggest that the adrenergic response is nonspecific and that the irises of both species receive primarily cholinergic innervation. however, both cholinergic and adrenergic agonists are capable of modifying the au ...19817341067
morphological analysis of the fish heart ventricle: myocardial and connective tissue architecture in teleost species.light and scanning electron microscopy were used to study the structure of the heart ventricle in three species of marine teleost fishes: the hake (merluccius merluccius), the angler fish (lophius piscatorius) and the sea bream (pagellus centrodontus). our findings show the ventricle to be shaped differently in each species: tubular in the hake, saccular in the angler fish and pyramidal in the sea bream. from a structural viewpoint, interest was centered on two aspects: organization of the myoca ...19957541184
in vitro biosynthesis of fish islet preprosomatostatin: evidence of processing and segregation of a high molecular weight precursor.evidence is presented for a precursor to somatostatin that is 10-12 times larger than the authentic secreted hormone. mrna from angler fish (lophius americanus) islets of langerhans was translated in the wheat germ cell-free system and the products were identified by immunoprecipitation with specific antibodies to somatostatin followed by sodium dodecyl sulfate gel electrophoresis. one 18,000-dalton polypeptide was specifically immunoprecipitable. competition experiments showed that authentic so ...19806107904

the importance of weight-normalized exposure data when issuing fish advisories for protection of public health.public health protection from environmental contaminants requires an understanding of the extent of contamination and of the extent of exposure to the contamination. my argument here is that weight-normalized, species-specific, individual-consumption pattern data are vital for determining exposure levels used to ascertain health protection measures and impacts from consuming contaminated fish. this study demonstrates the importance of adequate consumption pattern data for determining exposure di ...200212117644
the impact of angler groundbait on benthic invertebrates and sediment respiration in a shallow eutrophic reservoir.in an experiment to determine the impact of angler baits, cereal or maggots were added to areas of sediment in a eutrophic reservoir at realistic rates, over a 12-week period. the densities of benthic invertebrate taxa were estimated before treatment, immediately after treatment, and, finally, after a 4-month recovery period. all taxa except the tubificid limnodrilus hoffmeisteri were reduced in density by cereal baiting, the most sensitive being naidid worms and cladocerans. recovery of the ben ...198715092737
proposed methods and endpoints for defining and assessing adverse environmental impact (aei) on fish communities/populations in tennessee river reservoirs.two multimetric indices have been developed to help address fish community (reservoir fish assemblage index [rfai]) and individual population quality (sport fishing index [sfi]) in tennessee river reservoirs. the rfai, with characteristics similar to the index of biotic integrity (ibi) used in stream fish community determinations, was developed to monitor the existing condition of resident fish communities. the index, which incorporates standardized electrofishing of littoral areas and experimen ...200212805895
[persistent skin reaction and raynaud phenomenon after a sting by echiichthys draco (great weever fish)].a 54-year-old recreational angler was stung in his right forefinger by echiichthys draco. within a few seconds he developed severe swelling with extreme pain sensation at the sting site, accompanied by dizziness and chill. even under morphine therapy the pain symptoms were only slightly reduced. during the subsequent weeks, an erythema with marginate medium-sized scaling developed at the sting site and the patient experienced a approximately 50% reduced bending capacity of the forefinger and per ...200312835865
maternal fish consumption and infant birth size and gestation: new york state angler cohort study.the scientific literature poses a perplexing dilemma for pregnant women with respect to the consumption of fish from natural bodies of water. on one hand, fish is a good source of protein, low in fat and a rich source of other nutrients all of which have presumably beneficial effects on developing embryos and fetuses. on the other hand, consumption of fish contaminated with environmental toxicants such as polychlorinated biphenyls (pcbs) has been associated with decrements in gestation and birth ...200312826023
isolation of mycobacteria from frozen fish destined for human consumption.mycobacteria were isolated from defrost water and tissue of sole (solea solea), hake (merluccius merluccius), cod (gadus morhua), ling (genypterus blacodes), and monkfish (lophius piscatorius) on löwenstein-jensen medium after incubation at different temperatures. samples of frozen fish were obtained under sterile conditions inside a refrigeration chamber (-18 to -22 degrees c) in a wholesale market from which these products are distributed to shops for retail sale and human consumption.200010919833
birth defects risk associated with maternal sport fish consumption: potential effect modification by sex of offspring.contaminated sport fish consumption may result in exposure to various reproductive and developmental toxicants, including pesticides and other suspected endocrine disruptors. we investigated the relation between maternal sport fish meals and risk of major birth defects among infants born to members of the new york state (nys) angler cohort between 1986 and 1991 (n=2237 births). birth defects (n=125 cases) were ascertained from both newborn medical records and the nys congenital malformations reg ...200515533329

a critical analysis of illinois' fish mercury monitoring program, 1974-1998.mercury contamination in fish is a serious public health concern that contrasts with other health benefits of eating fish. like most us states, illinois has monitored fish mercury contamination for decades to warn the public of mercury exposure risks by consuming fish. has this monitoring program been effective in detecting public mercury exposure risks? i analyzed fish mercury contamination data from illinois inland lakes (1974-1998; > 2,300 samples, 18 fish species, 149 lakes) and found that: ...200717171274
do catch-and-release guidelines from state and provincial fisheries agencies in north america conform to scientifically based best practices?many recreational anglers practice catch-and-release angling, where fish are returned to the water with the presumption that they will survive. however, not all fish survive, and those that do often experience sublethal consequences including injury and stress. there is compelling scientific evidence that angler behavior and gear choice can affect the success of catch-and-release as a management and conservation strategy. because anglers often look to government natural resource agencies for gui ...200717387544
release method and anatomical hook location: effects on short-term mortality of angler-caught acanthopagrus australis and argyrosomus japonicus.one field and 3 aquaria experiments were done to quantify the short-term mortality of yellowfin bream acanthopagrus australis and mulloway argyrosomus japonicus after being angled and subjected to 3 general handling treatments. anglers were supplied with identical j-type hooks and asked to handle hooked fish by either (1) physically removing the hook or (2) cutting the line (5 cm from the mouth of the fish) and leaving the hook in. some hooked a. japonicus were subjected to a third handling trea ...200717425260
ingestion and ejection of hooks: effects on long-term health and mortality of angler-caught yellowfin bream acanthopagrus australis.ninety juvenile yellowfin bream acanthopagrus australis were angled from holding tanks, allowed to ingest nickel-plated, carbon-steel j-hooks and released (with their lines cut) into individual experimental tanks during 2 experiments in order to assess their (1) long-term (up to 105 d) health, mortality and rate of hook ejection and (2) short- and medium-term (< 42 d) temporal changes in health during hook ingestion. equal numbers of control fish were scooped from holding tanks and similarly mon ...200717425261
a deliberate approach for the syntheses of heterometallic supramolecules containing dimolybdenum mo(2)4+ species coordinated to other metal units.two compounds with quadruply bonded mo2(4+) species having isonicotinate ligands bound through the carboxylate group have been designed to act as anglers by luring metal-containing lewis acids to bind to the n-pyridyl group. the corner pieces are mo2(danif)3(o2cc5h4n) and cis-mo2(danif)2(o2cc5h4n)2, danif=n,n'-di(p-anisyl)formamidinate. the heterometallic molecular rods -ni(acac)2-and-rh2(o2cch3)4- were made by reaction of with ni(acac)2 and the metal-metal bonded species rh2(o2cch3)4, respectiv ...200717534494
