| some aspects of studies of thermal transitions in proteins by means of their intrinsic fluorescence. | the changes in intrinsic fluorescence parameters induced by thermal transitions in proteins are developed on the background of the common thermal fluorescence quenching due to an activation of collisions between the excited chromophores and neighbouring quenching groups. two methods of separation of the thermal quenching and conformational change contributions to the temperature dependence of the fluorescence parameters are presented. one is based on the use of the linearity of the plots of the ... | 1984 | 6722276 |
| intraoperative cardioplegic contrast echocardiography for assessing myocardial perfusion during open heart surgery. | aortic root hypothermic, hyperkalemic cardioplegic perfusion has been shown to preserve ventricular function during open heart surgery. however, significant coronary artery stenoses may prevent adequate perfusion of myocardial regions distal to the lesions, leading to intraoperative ischemia and damage. the purpose of this study was to evaluate for the first time in human patients the use of intraoperative contrast cardioplegic echocardiography for identifying potentially jeopardized myocardial ... | 1984 | 6333444 |
| pharmacological properties of immuno-isolated neuronal nicotinic receptors. | recently we immunoaffinity-purified an ach receptor from chicken brain using a monoclonal antibody raised against receptors from fish electric organ (whiting and lindstrom, 1986). this neuronal receptor could be affinity-labeled with 3h-bromoacetylcholine, and antisera to it specifically blocked ach-induced depolarization of chicken ciliary ganglion cells. here we show that this neuronal ach receptor binds 3h-nicotine with high affinity (kd = 6.61 +/- 0.13 nm). 3h-nicotine binding was blocked by ... | 1986 | 3531428 |
| structurally different neuronal nicotinic acetylcholine receptor subtypes purified and characterized using monoclonal antibodies. | acetylcholine receptors that bind nicotine with high affinity but do not bind alpha-bungarotoxin have recently been immunoaffinity purified from brains of chickens and rats (whiting and lindstrom, 1986a, b; whiting and lindstrom, 1987a). antisera to these receptors bind to the nicotinic receptors that regulate cation channel opening on chick ciliary ganglion neurons (stollberg et al., 1986) and rat pc12 cells (whiting et al., 1987c). here we report the preparation and characterization of monoclo ... | 1987 | 3694260 |
| antibodies in sera from patients with myasthenia gravis do not bind to nicotinic acetylcholine receptors from human brain. | nicotinic acetylcholine receptors (achrs) from brains of chickens and rats have recently been purified and characterized (whiting and lindstrom, biochemistry, 25 (1986) 2082-2093; j. neurosci., 6 (1986) 3061-3069; proc. natl. acad. sci. u.s.a., 84 (1987) 595-599). using both antisera and monoclonal antibodies prepared to achrs from rat brain, we have demonstrated the existence of a homologous achr in human brain. here we report that antibodies to muscle achrs in the sera of patients with myasthe ... | 1987 | 3624454 |
| red-edge-excitation fluorescence spectroscopy of single-tryptophan proteins. | with the aim of finding non-equilibrium dipole-relaxational electronic excited states of tryptophan residues in proteins the dependence of the fluorescence emission maximum on excitation wavelength was studied for several proteins containing a single tryptophan residue per molecule. spectral shifts upon red-edge excitation are not observed for short wavelength-emitting proteins (azurin, two-calcium form of whiting parvalbumin, ribonucleases c2 and t1). this may be because of the non-polar enviro ... | 1988 | 3208709 |
| [anisakids and human anisakiasis. 2. investigation of the anisakids of commercial fish in the district of paris]. | 1,173 fish belonging to 13 species were examined during 1986-1987, during a survey conducted among commercial marine fish in the paris area (france). anisakis simplex l3 were found in 10 different species, and most frequently in herring (clupea harengus) 82.55% of 682 fish, red fish (sebastes marinus) 86.11% of 36 fish, and hake (merluccius merluccius) 88.57% of 35 fish, and in high number (average 8.8, 18.4 and 31 l3 per fish). pseudoterranova decipiens l3 were recovered from 7 different specie ... | 1988 | 3190121 |
| characterization of bovine and human neuronal nicotinic acetylcholine receptors using monoclonal antibodies. | neuronal acetylcholine receptors (achrs), which bind nicotine with high affinity but do not bind alpha-bungarotoxin (alpha bgt), have recently been immunoaffinity-purified from chicken (whiting and lindstrom, 1986a) and rat (whiting and lindstrom, 1987a) brain using monoclonal antibodies (mabs). here we report the characterization of nicotinic achrs of bovine and human brain using as probes mabs prepared to achrs from rat brain. both the human and bovine brain achrs exhibit high affinity for l-n ... | 1988 | 3171681 |

| the effects of ciguatoxin on the nerves of the teleost fish, sillago ciliata. | the absolute refractory period, relative refractory period, and the duration and magnitude of the supernormal period were measured after incubation of fish nerves with ciguatoxin and other channel modifying compounds, tetrodotoxin, veratridine, verapamil, and lignocaine. in vitro electrophysiological studies were carried out on the lateral line nerve of the whiting, sillago ciliata cuvier. electrophysiological changes in fish nerves after exposure to ciguatoxin (0.3 mu.ml-1) and veratridine (1 x ... | 1992 | 1344907 |
| differential localization of two alternatively spliced gabaa receptor gamma2-subunit mrnas in the chick brain. | two variants of the gabaa receptor gamma2 subunit are known to exist, which differ by the presence (gamma2l) or absence (gamma2s) of eight amino acids in the presumed intracellular loop between the third and fourth membrane-spanning domains. these variants have been shown to be generated by alternative splicing of the gamma2-subunit primary gene transcript in mouse (kofuji et al., j. neurochem., 56, 713 - 715, 1991), and in bovine and human (whiting et al., proc. natl. acad. sci. usa, 87, 9966 - ... | 1992 | 12106372 |
| influence of dietary fish proteins on plasma and liver cholesterol concentrations in rats. | the effects of amount and type of dietary fish proteins on plasma and liver cholesterol concentrations were evaluated in female rats. the isonitrogenous diets used contained 10 g cholesterol/kg and were carefully balanced for residual fat, cholesterol, ca, mg and p in the protein preparations. cod meal, soya-bean protein or casein was incorporated into the diets as the only source of dietary protein at three levels: either 24, 48 or 72 g n/kg diet. extra protein was added to the diet at the expe ... | 1993 | 8329352 |
| immunoglobulin-type domains of titin: same fold, different stability? | titin is a 3-mda protein thought to form a fibrous intracellular system in vertebrate striated muscle and to play an important role in sarcomere alignment during muscle contraction. it has also been implicated as a "molecular ruler", regulating the assembly and the precise length of the thick filaments [whiting, a. j., wardale, j., & trinick, j. (1989) j. mol. biol. 205, 163-169]. partial sequencing of titin-encoding cdnas suggests that the protein is organized in a modular fashion, containing t ... | 1994 | 8161531 |
| [anisakiasis in the nantes area. from fishmongers' stalls to medical offices]. | 1,103 fish-fillets belonging to 4 species were examined during one year, during a survey conducted among commercial marine fish-fillets in the nantes area (west coast) in france. anisakis simplex l3 were found in 3 different species and most of them are frequently present in coal fish (pollachius virens) and whiting (merlangius merlangus). we report 6 cases of human anisakiasis (3 certain cases and 3 probably cases). diagnosis was established in 3 cases by microscopic analysis of intestin bowel ... | 1995 | 8745739 |

| nmda receptor subunit gene expression in the rat brain: a quantitative analysis of endogenous mrna levels of nr1com, nr2a, nr2b, nr2c, nr2d and nr3a. | electrophysiological recordings have shown nmda receptors to be heterogenous structures capable of responding to selected antagonists and agonists in multiple ways. this diversity in functional response has led investigators to conclude that these channels are comprised of unique combinations of receptor subunits which determine a cell's functional nmda-signature [h. meguro, h. mori, k. araki, e. kushiya, t. kutsuwada, m. yamazaki, t. kumanishi, m. arakawa, k. sakimura, m. mishina, functional ch ... | 1999 | 10366738 |
| anisakidae larval infection in fish fillets sold in belgium. | fish fillets (n = 1760) sold on the belgium market were examined for anisakidae larval infection. seven sea fish species were examined by means of the candling technique over a period of 4 months, from november 1996 to february 1997. third-stage larvae of anisakis simplex and pseudoterranova decipiens were identified. a. simplex was the most abundant species with a prevalence of 84.5%, and was found in 192 of the examined fillets (10.9%). pollock (pollachius pollachius) was the most heavily infe ... | 1999 | 10321017 |
| a mathematical model for bacterial inactivation. | the first order kinetic model, the buchanan model and cerf's model, can model a linear survival curve, a survival curve with a shoulder and a survival curve with a tailing, respectively. however, they are not suitable for fitting a sigmoidal survival curve. the three models were integrated into a new model that was capable of fitting the four most commonly observed survival curves: linear curves, curves with a shoulder, curves with a tailing (biphasic curves) and sigmoidal curves. the new model ... | 1999 | 10050684 |
| structural model requirements to describe microbial inactivation during a mild heat treatment. | the classical concept of d and z values, established for sterilisation processes, is unable to deal with the typical non-loglinear behaviour of survivor curves occurring during the mild heat treatment of sous vide or cook-chill food products. structural model requirements are formulated, eliminating immediately some candidate model types. promising modelling approaches are thoroughly analysed and, if applicable, adapted to the specific needs: two models developed by casolari (1988), the inactiva ... | 2000 | 11020040 |
| ultrastructure and small-subunit ribosomal dna sequence of henneguya lesteri n. sp. (myxosporea), a parasite of sand whiting sillago analis (sillaginidae) from the coast of queensland, australia. | henneguya lesteri n. sp. (myxosporea) is described from sand whiting, sillago analis, from the southern queensland coast of australia. h. lesteri displays a preference for the pseudobranchs and is typically positioned along the afferent blood vessels, displacing the adjoining lamellae and disrupting their normal array. the plasmodia appeared as whitish-hyaline, elliptical cysts (mean dimensions 230 x 410 microm) attached to the oral mucosa lining of the hyoid arch on the inner surface of the ope ... | 2001 | 11710554 |
| distribution of viral haemorrhagic septicaemia virus in wild fish species of the north sea, north east atlantic ocean and irish sea. | a surveillance programme was initiated on the occurrence and distribution of viral haemorrhagic septicaemia virus (vhsv) in wild marine fish. six research cruises were undertaken in an 18 mo period during 1997 and 1998, covering the north sea, the atlantic waters off the north and west coasts of scotland and the irish sea. a total of 19,293 fish were sampled from 23 different species including cod, haddock, norway pout, herring and sprat. individual fish lengths were recorded and the fish were c ... | 2001 | 11775798 |
| overexpression of the gaba(a) receptor epsilon subunit results in insensitivity to anaesthetics. | the epsilon -subunit of the gaba(a) receptor was independently cloned and functionally characterised in recombinant expression systems by two groups (davies, p.a. et al., nature 385 (1997) 820; whiting, p.j. et al., journal of neuroscience 17 (1997) 5027). both groups showed that co-expression of alphabeta epsilon -subunits produced functional receptors, however the sensitivity of these receptors to the potentiating effects of general anaesthetic agents differed. co-expression of the two epsilon ... | 2002 | 12367611 |
| levels of polybrominated diphenyl ether (pbde) flame retardants in animals representing different trophic levels of the north sea food web. | the levels of individual pbde congeners were investigated in the invertebrate species whelk (buccinum undatum), seastar (asterias rubens), and hermit crab (pagurus bernhardus), the gadoid fish species whiting (merlangius merlangus) and cod (gadus morhua), and the marine mammal species harbor seal (phoca vitulina) and harbor porpoise (phocoena phocoena). these species are all important representatives of different trophic levels of the north sea food web. all six major pbde congeners detected (bd ... | 2002 | 12380070 |
| acute co2 tolerance during the early developmental stages of four marine teleosts. | ocean sequestration of co2 is proposed as a possible measure to mitigate climate changes caused by increasing atmospheric concentrations of the gas, but its impact on the marine ecosystem is unknown. we investigated the acute lethal effect of co2 during the early developmental stages of four marine teleosts: red sea bream (pagrus major), japanese whiting (sillago japonica), japanese flounder (paralichthys olivaceus), and eastern little tuna (euthynnus affinis). the percentages of larvae that hat ... | 2003 | 14608607 |
| spatial analysis of stable isotope data to determine primary sources of nutrition for fish. | carbon and nitrogen stable isotopes were used to determine the ultimate autotrophic sources supporting production of three commercially important fish species over unvegetated mudflats in a subtropical estuary. mean isotope values over the whole estuary for fish and autotroph sources were modeled to indicate feasible combinations of sources. variability in isotope values among nine locations (separated by 3-10 km) was then used as a further test of the likelihood that sources were involved in fi ... | 2003 | 12774226 |
| the distribution of octachlorostyrene (ocs) in environmental samples from europe. | although octachlorostyrene (ocs) was never used as a commercial product, it may be produced during incineration and combustion processes involving chlorinated compounds. its environmental spreading was evaluated through the analysis of several representative samples. ocs could not be measured in soil samples collected from urban and rural areas or sediments, but was present (up to 5.41 ng/g dry weight) in industrial soil collected near chemically polluted areas. for aquatic biota samples, the oc ... | 2003 | 12948238 |
| extracellular production of a functional soy cystatin by bacillus subtilis. | a recombinant bacillus subtilis producing soy cystatin was developed by subcloning with a soy cystatin gene cloned in escherichia coli. an active form of cystatin against the cysteine protease from pacific whiting fillets contaminated with myxosporidia parasite was constitutively expressed and secreted extracelluarly into the medium. two gene fragments of signal peptides from kera and sacb were introduced and compared for secretion efficiency of cystatin. the secretion level of active cystatin i ... | 2004 | 15291474 |
| a united residue force-field for calcium-protein interactions. | united-residue potentials are derived for interactions of the calcium cation with polypeptide chains in energy-based prediction of protein structure with a united-residue (unres) force-field. specific potentials were derived for the interaction of the calcium cation with the asp, glu, asn, and gln side chains and the peptide group. the analytical expressions for the interaction energies for each of these amino acids were obtained by averaging the electrostatic interaction energy, expressed by a ... | 2004 | 15388862 |
| modelling the effect of a temperature shift on the lag phase duration of listeria monocytogenes. | the aim of this work is to study and model the effect of a temperature shift on h(0), the product of the growth rate by the lag phase duration (mulambda). our work is based on the data of whiting and bagi [int. j. food microbiol. 73 (2002) 291], who studied the influence of both the pre-incubation temperature (t(prior)) and the growth temperature (t(growth)) on lambda values of listeria monocytogenes. we introduce a new model to describe the evolution of the parameter h(0) as a function of t(pri ... | 2004 | 15854694 |
| changes in fisheries discard rates and seabird communities. | it is clear that discards from commercial fisheries are a key food resource for many seabird species around the world. but predicting the response of seabird communities to changes in discard rates is problematic and requires historical data to elucidate the confounding effects of other, more 'natural' ecological processes. in the north sea, declining stocks, changes in technical measures, changes in population structure and the establishment of a recovery programme for cod (gadus morhua) will a ... | 2004 | 14973483 |
| taqman dna technology confirms likely overestimation of cod (gadus morhua l.) egg abundance in the irish sea: implications for the assessment of the cod stock and mapping of spawning areas using egg-based methods. | recent substantial declines in northeastern atlantic cod stocks necessitate improved biological knowledge and the development of techniques to complement standard stock assessment methods (which largely depend on accurate commercial catch data). in 2003, an ichthyoplankton survey was undertaken in the irish sea and subsamples of 'cod-like' eggs were analysed using a taqman multiplex, pcr (polymerase chain reaction) assay (with specific probes for cod, haddock and whiting). the taqman method was ... | 2005 | 15723679 |
| seasonal dynamics of trichodina spp. on whiting (merlangius merlangus)in relation to organic pollution on the eastern black sea coast of turkey. | it was determined that there is a relationship between prevalence and mean densities of trichodina spp. on merlangius merlangus and organic pollution, measured as levels of nitrite, nitrate and phosphate in the surrounding environment. monthly, two left anterior gill arcs of 60 m. merlangus (unless otherwise stated) captured with hook and line were fixed in 10% formalin. the number of trichodina spp. was determined by counting all of the cells with a grid slide. the two right anterior gill arcs ... | 2005 | 15856300 |
| growth of listeria monocytogenes on iceberg lettuce and solid media. | the growth of pathogenic bacterium listeria monocytogenes on fresh-cut iceberg lettuce under constant temperatures was modelled in order to investigate microbial safety during distribution of this vegetable. we examined the effects of several incubation temperatures, ranging from 5 to 25 degrees c, on bacterial growth. these data were fitted to the baranyi model and the curves showed a high correlation coefficient at all temperature (r2 > 0.95). in addition, the native bacterial flora of the let ... | 2005 | 15862883 |
