Alternate Ways of obtaining Probes. With the vast numbers of FISH papers written, you can always ask other researchers for probes (6,14). There are probe databanks on the WorldWideWeb and some are given in the list of Web sites shown in Note 10. You can also develop them yourself (13), or with the aid of a commercial company like Genome Systems Inc. (22,23). This can be expensive, but are very efficient.

Since the individual cells of a spin-dependent liquid-electrolyte reserve battery are generally annular in shape and are filled by centrifugal force, the periphery of the cell must be sealed to keep electrolyte from leaking out. This sealing is typically accomplished by a plastic barrier formed around the outside of the electrode-spacer stack. For lead/fluoboric acid/lead dioxide batteries, this barrier is formed by fish paper (a dense, impervious paper) coated with polyethylene that melts at a relatively low temperature (similar to that used on milk cartons). Cell spacers are punched from the coated fish paper and placed between the electrodes. The stack is then clamped together and heated in an oven at a temperature sufficient to fuse the polyethylene, which then acts as an adhesive and sealer between the electrodes. 

In this paper, the technique for investigation fish otoliths using the microanalyzer Supei probe-733 (JEOE Etd, Japan) has been elaborated. 

Direct geothermal energy is used for space heating of homes, greenhouses, livestock barns, and fish-farm ponds. As well, it is employed as a heat source in some industrial processes, such as paper production in New Zealand and diying diatomite in Iceland. Since the industrial applications usually require high-... 

The primary industries are pulp and paper, lumber, electronics, and tourism. The basin supports extensive wildlife and fish habitat. Precipitation varies from 100 cm at the basin floor to more than 300 cm in the Cascade Range and summers are dry and warm with winters cloudy and wet. Daily average temperatures in the basin range from 1.7 C in winter to 28°C in summer. A cross-sectional profile of the basin is shown in Figure 2A. Figure 2B identifies specific morphological reaches of the main stem Willamette River. 

Venom is secreted from the dorsal, pelvic and anal spines. A review of original papers indicates that many papers have failed to specify from which spine the venom was obtained. Therefore, some publications are meaningless scientifically. Not a single component of fish venoms has been characterized for the amino acid sequence yet. Even the molecular weight of fish toxins is not clear. Deakins and Saunders (25) concluded that the molecular weight of Scorpaena toxin was 150,000, while Schaeffer et al. (26) concluded that it had a molecular weight range of 50,000 to 800,000. 

In the last fifteen years there has been considerable interest in the analysis of volatile N-nitrosamines in foods. The primary focus has been on meat cured with nitrite (3 ) although nitrosamines have been shown to occur occasionally in other foods such as fish and cheese (, 3) Recently, attention has been directed to volatile nitrosamines in beer and other alcoholic beverages. The purpose of this paper is to review current information on the presence of nitrosamines in beer, and to discuss work done in our laboratory and elsewhere on the mode of formation of nitrosamines in beer. 

CRMs for Contaminants in Environmental Matrices For nearly two decades NIST has been involved in the development of SRMs for the determination of organic contaminants such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and chlorinated pesticides in natural environmental matrices such as fossil fuels (Hertz et al.1980 Kline et al. 1985), air and diesel particulate material (May and Wise 1984 Wise et al. 2000), coal tar (Wise et al. 1988a), sediment (Schantz et al. 1990, 1995a Wise et al. 1995), mussel tissue (Wise et al. 1991 Schantz et al. 1997a), fish oil, and whale blubber (Schantz et al. 1995b). Several papers have reviewed and summarized the development of these environmental matrix SRMs (Wise et al. 1988b Wise 1993 Wise and Schantz 1997 Wise et al. 2000). Seventeen natural matrix SRMs for the determination of organic contaminants are currently available from NIST with certified and reference concentrations primarily for PAHs, PCBs, chlorinated pesticides, polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofiirans (PCDFs) see Table 3.11. 

I think I was only curious to see what would happen, though I must have known what might. I d been at the university for a year, after all. And why with him, whom I ll have to think of as Nigel There s something about the remembered smell of the gas fire and the sofa—soot and old fish-and-chip papers—that tells me my reasons weren t romantic ones. 

Bouin s solution is one of the traditional ways to harden cell pellet. Some cytologists believe it provides the best cellular details, especially nuclear features in cell blocks.28 The major steps are (1) After centrifugation, fix the cell pellet with Bouin s solution. (2) After 2h, discard the solution. (3) Remove the hardened cell pellet from the tube, wrap it with lens paper, and transfer it into a cassette for further processing. We have been using this method for many years. In our experience, most of the time, ICC results are consistent with IHC from the surgical specimen. The biggest drawback of this method is the toxicity of Bouin s fixative which creates biohazard and safety issues for the laboratory. We also found cell blocks gave poor fluorescence in situ hybridization (FISH) results after Bouin s fixation. 

The Ebro catchment is the largest river basin in Spain. It covers an area of 85,362 km2 (http //www.chebro.es) and receives the potential influence of three million people. It suffers a considerable ecological impact from different industrial activities located predominantly in the last third of its course. These activities result on the release to the Ebro River and to some of its tributaries of Tm quantities of chlorinated organic compounds, PBDE and other brominated flame retardants, mercury, and other metals. In addition, intensive agricultural practices, mainly concentrated in the last 30 km of the river course and in its Delta, imply the use of large quantity of pesticides and fertilizers. In this paper, we review physiological effects of these pollutants in resident fish and shellfish populations and provide a general picture of the health status of the low course of the Ebro River. 

This area was the most profusely studied in the AQUATERRA project in terms of biological effects in fish populations. Barbel and bleak were the sentinel species selected in this area and an array of histological and biochemical tests were used to monitor the impact due to three major sources of pollution mercury and OCs at Monzon (with a comparison in one of the papers with Flix) and PBDEs in Barbastro [1—4, 37]. Mercury pollution was directly correlated to an increase of MTprotein in the liver of barbel captured downstream Monzon when compared to samples captured upstream (Fig. 3a). However, mRNA quantitative analyses failed to show any differences between downstream and upstream Monzon, neither correlated with MT protein levels. Further studies showed that MT mRNA in liver is a rather weak marker for chronic metal pollution in liver (see below) [4], The presence of degenerative hepatocytes in barbels and bleaks was also linked to mercury poisoning although it can also reflect the impact by other pollutants, like OCs or PBDEs (Fig. 3e).
