Pempheris ypsilychnus is distinguished from all other members of the Pempherididae by the following combination of characters: all scales ctenoid and adherent; pelvic axillary scale present; lateral-line scales 62-74 (usually 63-69); gill raker counts on first arch 6-8 + 19-22 = 25-30 (usually 26-27); dark, Yshaped light organ visible through body wall between pelvic- and anal-fin origins, with its bifurcation around anus (Fig. 8). Description. Dorsal-fin rays VI,lO (VI,lO; V-VI,9-11, V only once, rarely 11); anal-fin rays III,33 (III,34; Ill,30-36, once 30); pectoral-fin rays 17 (17; 16-18); pelvic-fin rays 1,5; principal caudal-fin rays 9+8; upper procurrent rays 6,2 (6,2; 5-8,1-2); lower procurrent rays 3,2 (3,2; 3-5,1-2); lateral-line scales 64 (68; 62-74, rarely more than 70); scale rows above lateral line 9 (10; 9-11); scale rows below lateral line 18 (18; 17- 21); cheek scale rows 7 (6-9, extremes less common); predorsal scales 39 (39; 35-45, usually 37-43); circumpeduncular scales 22 (24; 22-26, usually 23-24); gill rakers 6+21 (7+20; 6-8, rarely 8 + 19-22); total gill rakers 27 (27; 25-30, most frequently 26-27, once 30). As percentage of SL: head length 35.2 (34.5; 31.8- 39.4); head depth 33.7 (34.0; 30.0-39.7); snout length 7.7 (7.0; 5.8-8.l); eye diameter 14.8 (15.1; 13.2-16.5); interorbital width 8.9 (8.0; 6.5 -9.3); upper jaw length 19.0 (19.0; 17.3-20.5); predorsal length 41.0 (40.0; 36.1-44.7); prepelvic length 38.1 (38.7; 33.8-49.3); preanal length 57.8 (59.9; 54.0-66.1); pelvic-fin origin to anal-fin origin 22.5 (24.5; 19.8-29.6); body depth 43.8 (41.9; 37.1-46.0); pectoral-fin length 28.2 (27.9; 24.1 -31.7); pelvic-fin length 19.2 (19.6; 17.4-21.8); dorsal-fin base 20.6 (20.3; 18.1-23.0); longest dorsalfin ray 24.8 (24.3; 20.7-26.8); anal-fin base 43.1 (43.2; 40.5-46.0); longest anal-fin ray 19.8 (18.7; 15.0 -21.7); caudal-peduncle length 12.0 (10.7; 9.0-13.0); caudalpeduncle depth 10.8 (10.5; 9.2 -11.3); dorsal-fin origin to pelvic-fin origin 42.8 (41.5; 36.3-44.9); dorsal-fin origin to anal-fin origin 45.9 (45.3; 39.6-51.1); dorsalfin origin to anal-fin insertion 57.9 (57.2; 43.9-60.9). Caudal fin forked. All scales ctenoid and adherent. Gular scaled. Pelvic axillary scale present. Prepelvic area (breast) unkeeled, flat and broad. Anterior and posterior light organs V-shaped (Fig. 4b, 8). Anterior organ communicates with pyloric caeca, forward extension consisting of two ducts that unite anteriorly. Anterior organ underlain by pigmented tissue and layer of translucent muscle. Posterior organ communicates directly with the rectum (Haneda et al., 1966: 537), underlain by a layer of pigmented tissue. Coloration. Live colour unknown. Holotype preserved in 70% ethanol (Fig. 7): dorsal part ofhead, nape, and body yellowish or straw and speckled with tiny dark brown chromatophores; cheek and particularly opercular area darker; preventral area anterior to pelvic-fin bases pale yellow and without chromatophores; dentaries without chromatophores, permitting dark bar on gular to show through; lower part of cheek dark; dark, Yshaped light organ visible through body wall between pelvic- and anal-fin origins, with wide bifurcation around the anus, silvery margins along length of linear portion; iris black; lateral-line scales without chromatophores making lateral line obvious on lightly speckled body; dorsal fin hyaline, with, at most, distal 1/4 of spines and first three segmented rays dark; anal fin hyaline, with distal 1/4 of first two segmented rays dark; pectoral and pelvic fins hyaline; medial caudalfin rays hyaline and speckled with tiny chromatophores, with bases yellow, three outermost branched rays and adjacent unbranched rays with black tips that gradually fade proximally. Colours of other preserved specimens very similar, differing in the following: variation in amount of black on tips of fins from none to 1/3 their length; occasionally silvery flanks; sometimes few or no chromatophores speckling body, sometimes more chromatophores, especially on ventral part of head; Yshaped light organ often with silver margins over entire length; iris sometimes coppery. Comparisons. In Australia, this species is most likely to be confused with P. analis, P. compressa, and P. klunzingeri. Among these ctenoid-scaled Pempheris species, only P. ypsilychnus bears a pelvic axillary scale and has a Y-shaped posterior light organ visible through the body wall (Fig. 8). It is the only member of the genus with a Y-shaped anterior light organ (Fig. 4b). Total gill raker counts for P. ypsilychnus are considerably lower than other ctenoid-scaled members of the genus (25- 30 vs. 31-38). P. klunzingeri has the most similar body shape, but has five dorsal spines (vs. six) and a longer anal fin (anal-fin base:SL ratio 0.47-0.55, mean 0.51 vs. 0.41-0.46, mean 0.43) due to a higher number of segmented anal-fin rays (35-41 vs. 30-36); it also tends to have higher lateral-line scale counts (66-80, usually>70 vs. 62-74, usually 63-69) and the anterior light organ is restricted to a mop-like mass of tissue communicating with the pyloric caeca (Fig. 4c). P. analis tends to be deeper bodied (dorsal origin to pelvic origin:SL ratio 0.41 -0.46, mean 0.44 vs. 0.36-0.45, mean 0.42) with a longer anal-fin base (anal-fin base:SL ratio 0.43-0.49, mean 0.46 vs. 0.41-0.46, mean 0.43); additionally, it has no anterior light organ. P. compressa generally has higher numbers of segmented anal-fin rays (34-40 vs. 30-36) and, hence, a longer anal-fin base (anal-fin base:SL ratio 0.52-0.58, mean 0.54 vs. 0.41- 0.46, mean 0.43); it has no anterior light organ. Distribution. Specimens have been collected at a number of sites in northern Australia, from the central west coast of Western Australia to the southern Great Barrier Reef (Fig. 6). The southernmost record on the east coast, Moreton Bay near Brisbane, was reported by Haneda et al. (1966: 537) as Pempheris klunzingeri (a misidentification). Biology. Little is known about this species. The largest known maximum size is 120.6 mm SL, and capture depths range from 1 m to 24 m. Haneda et al. (1966: 537) studied specimens obtained in a shrimp trawl, and described the anterior light organ as V-shaped, apparently overlooking the anterior portion of this structure (Fig. 4b). Body depth (measured as dorsal-fin origin to pelvicfin origin) varies geographically. Specimens from western localities (Shark Bay to Broome) have deeper bodies than those from eastern localities (Gulf of Carpentaria to Port Denison) (0.40-0.45, mean 0.43 vs. 0.36-0.42, mean 0.40; means significantly different, T=6.79, DF=60, p<O.OOl). Eastern specimens tend to have higher lateralline scale counts and more segmented anal-fin rays than western specimens (Tables 2, 3); the higher anal-fin ray counts are particularly noticeable among Gulf of Carpentaria examples (Table 3). Etymology. The specific name is a combination of ypsilon, the Greek letter Y, and lychnos, Greek for lamp or light. This combination alludes to the Y-shaped posterior organ that is visible through the body wall and characteristic of this species, reported to be luminescent (Haneda et al., 1966). The epithet is to be treated as a noun in apposition. Discussion. The relationships of these two new species cannot be determined at present. Preliminary results from a systematic revision of the family Pempherididae by the senior author, as well as the character distributions described by Tominaga (1968) and Jubb (1977), provide reason to doubt the monophyly of the two included genera, Parapriacanthus and Pempheris. The two new species exhibit the external features that traditionally have been used to characterise Pempheris (deep body, anal fin in scaly sheath, lateral-line scales extending to posterior margin of caudal fin), but share a number of internal features with the members of Parapriacanthus (cleithrum morphology, Y-shaped anterior light organ in Pempheris ypsilychnus). Their placement in Pempheris should, therefore, be regarded as provisional. Below is a key to the Australian species ofPempheris. In Australian waters, Pempheris can be distinguished from Parapriacanthus by: anal fin in scaled sheath (vs. no scaly sheath), 27 or more segmented anal-fin rays (vs. 27 or fewer), lateral-line extending to distal tips of medial caudal-fin rays (vs. to middle of medial caudal-fin rays), deeper body (head length about equal to body depth vs. head length generally greater than body depth). The key is provisional in two respects. First, the membership of Pempheris, as noted, is subject to change until the genus can be diagnosed by synapomorphies. Second, the identification of species of cycloid-scaled Pempheris, excepting perhaps P schwenkii, is questionable pending completion of a worldwide revision. Colour patterns noted below are those of adults. Distributions are taken from examined specimens and records in Hutchins (1994) and Hutchins & Swainston (1986). The authorship of P compressa to White (1790) follows the recommendation ofPaxton et al. (1989: 12).Published as part of Mooi, R. D. & Jubb, R.

Assessment of tumour hypoxia for prediction of response to therapy and cancer prognosis
No full textTumour cells exploit both genetic and adaptive means to survive and proliferate in hypoxic microenvironments, resulting in the outgrowth of more aggressive tumour cell clones. Direct measurements of tumour oxygenation, and surrogate markers of the hypoxic response in tumours (for instance, hypoxia inducible factor-1α, carbonic anhydrase 9 and glucose transporter-1) are well-established prognostic markers in solid cancers. However, individual markers do not fully capture the complex, dynamic and heterogeneous hypoxic response in cancer. To overcome this, expression profiling has been employed to identify hypoxia signatures in cohorts or models of human cancer. Several of these hypoxia signatures have demonstrated prognostic significance in independent cancer datasets. Nevertheless, individual hypoxia markers have been shown to predict the benefit from hypoxia-modifying or anti-angiogenic therapies. This review aims to discuss the clinical impact of translational work on hypoxia markers and to explore future directions for research in this area. © 2009 The Authors Journal compilation © 2010 Foundation for Cellular and Molecular Medicine Blackwell Publishing Ltd

Holotype when freshly dead (Fig. 1): background colour on cheek, opercle, and body below lateral line iridescent silver; dorsal head, nape, and body above lateral line greyish to reddish; medial dark stripe along predorsal scales to dorsal-fin origin; dark stripe at level of dorsal part of eye extending to opercular opening, then merging with the upper-most body stripe; margins of jaws dark; lower part of cheek dark; iris yellowish; body below dorsal fin with 7 golden-brown stripes, with middle stripes brightest by having fewest darker chromatophores; number ofbody stripes decreasing posteriorly to three on caudal peduncle, ending at base of caudal-fin rays; stripes become increasingly reddish posteriorly; all fins with pinkish to reddish cast; dorsal fin pinkish hyaline, with dark anterior edge and dark distal tips on last two spines and first three segmented rays; anal fin quite red basally and on first few segmented rays, remainder pinkish hyaline with black tips on all but last 5 segmented rays, black covering 113 length of first 3 rays and about 114 length of remaining rays; pectoral fin pinkish hyaline; pelvic fin reddish hyaline, with distal 114 of first two segmented rays black; caudal fin reddish hyaline, with black tips on outermost branched rays. Colours from photographs of live individuals very similar to those of holotype, except for the following (Figs. 2,3; Allen, 1985: fig. 229; Gomon, 1994: fig. 536; unpublished photos by R. Kuiter): body background pale or cream-coloured, the posterior body and caudal peduncle sometimes transparent; stripe behind eye bright yellow or golden-brown; iris bright yellow; lower part of cheek with scattered yellow chromatophores; body stripes much brighter yellow; fins usually less reddish with less obvious black tips. In 70% ethanol: cheek, opercle, and area below pectoral fin and sometimes lower part of abdomen silvery; dorsal part of head and nape dusky; remainder ofbody straw-coloured; stripes present as series of dark chromatophores, sometimes only 6 (rather than 7) from ventral abdomen to dorsal-fin base; fins yellowish with similar pattern of dark tips as described above, although black coloration variable in extent; black, silver-margined, linear light organ associated with rectum visible through body wall (Fig. 5), becoming slightly bifurcate around anus. Comparisons. The only species with vaguely similar coloration to P ornata are P multiradiata and colour forms of what is presently referred to as P oualensis. In these two species the longitudinal stripes are brown or reddish-brown (vs. orange or yellow) and more numerous (8 or more on the body vs. 6-7). Within the genus, P ornata has uniquely low counts of lateral-line scales (32-39) and anal-fin rays (27- 30). P multisquamata has the lowest lateral-line scale counts among remaining Pempheris species (42-49). Only P analis and the new species P ypsilychnus overlap the uppermost portion of the anal-fin ray count (30-36); both of these species have ctenoid (vs. cycloid scales), lateral-line scale counts of well over 60, and are without any longitudinal striping. Distribution. Specimen localities are limited to areas along the southwest and south coast of Australia, from Rottnest Island (near Perth) to Rapid Bay Gust south of Adelaide) (Fig. 6). The species also has been reported north to Dongara (= Port Denison), Western Australia (Hutchins & Swainston, 1986; Hutchins, 1994). Biology. The species is reported as sometimes congregating beneath piers and near jetties and not often sighted during the day (Gomon, 1994). The deepest recorded collecting site is 30 m. This is the smallest member of the genus Pempheris, not known to exceed much more than 75 mm SL. The smallest gravid female measured 56 mm SL. The only geographic difference in meristics noted was a slightly lower total number of gill rakers on the first arch for the easternmost collections (Kangaroo Island, Rapid Bay) compared to western collections (Rottnest Island, Recherche Arch.) (modes of 28 vs. 30 -31) (Table 1). However, more specimens are needed to establish whether or not these differences are significant. Etymology. The specific name comes from the Latin ornamentum, meaning ornamented or ornate, in reference to the spectacular coloration of this species compared to its congeners. It is to be treated as a noun in apposition.Published as part of Mooi, R. D. & Jubb, R.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
