Australian species of the genus Australonura (Collembola : Neanuridae)
Authors: Greenslade P , Deharveng L
Published: April 2005

The genus Australonura Cassagnau 1980 is defined; four species already known from Australia, A. grossi the type species, A. cirrata, A. meridionalis and A. wellingtonia, are redescribed with the aid of new material. Eight new species are described, A. ahimsa, A. beata, A. grandes, A. norfolkensis, A. quarta, A. sanguisugarum, A. scoparia, and A. redita; provisional phylogenetic relationships are discussed for the Australian members of the genus.
Correction - The Australasian genera of pericomoid Psychodidae (Diptera) and the status of related Enderlein genera in the neotropics
Authors: Duckhouse DA
Published: April 2005

Australasian pericomoids, psychodids resembling northern hemisphere species of Pericoma Walker (tribe Pericomini), are mostly members of the tribe Maruinini, here re-defined. Amongst Maruinini, they are like several neotropical genera named by Enderlein (1937), but their actual relationship to Enderlein's genera, and hence their identity, has been a long-standing taxonomic problem. Consideration of extensive new collections and observations made in the southern hemisphere now shows that they consist of the following: Genus Notiocharis Eaton. Tribe Maruinini: genus Didicrum Enderlein, and five new genera, Eremolobulosa, Rotundopteryx, Alloeodidicrurn, Satchellomyia and Ancyroaspis. Of these, the Australian Eremolobulosa is the possible sister group of the European Lobulosa Szabo, and the New Zealand genera Satchellomyia and Ancyroaspis are possible sister groups. Of Enderlein's neotropical genera, five classified by Quate (1963) as synonyms, or in one case a subgenus, of Pericoma (Didicrum, Desmioza, Synmormia, Syntomolaba and Podolepria) are recognised as full genera. A key to Australasian pericomoid genera is provided.
Vicmusia duplocoxa, gen. et sp.nov., (Crustacea : Amphipoda : Gammaridea) of the new family Vicmusiidae from Australian upper bathyal waters
Authors: Just J
Published: April 2005

Vicmusia duplocoxa, gen, et sp. nov., from a depth of 400 m in the Bass Strait Canyon off south-eastern Australia is described. The species possesses three unique apomorphisms: pereonal and pleonal tergites are divided laterally (one dorsal and two lateral subplates to each tergite); coxal plate 2 is strongly reduced among long plates 1, 3 and 4; mouthparts are produced into a setose forward-pointing funnel. The species cannot readily be placed in any of the currently diagnosed gammaridean superfamilies or families, so the new family Vicmusiidae is erected but for now is left as Gammaridea, incertae sedis.

On four endemic genera of Tasmanian Acrididae (Orthoptera)
Authors: Key KHL
Published: April 2005

Two endemic Tasmanian genera of catantopine Acrididae, Truganinia and Tasmanalpina, are newly described, and two others, Russalpia Sjöstedt and Tasmaniacris Sjöstedt, redescribed. All but Russalpia (two species) are monotypic, and all are micropterous except Truganinia (mesopterous). The genera are closely related to some of the endemic New Zealand Acrididae, especially in the male genitalia, which must have suffered little modification over the past 50 million years. The species are described and figured, and their distributions plotted and interpreted in relation to historical geographic and climatic changes.
A new genus and two new species of plant Nematode (Tylenchidae) from Australia
Authors: Reay F
Published: April 2005

A new genus and two new species of plant-parasitic nematodes from Australia are described. Arboritynchus simpsoni, gen. nov., sp. nov., collected from rainforest in northern New South Wales is related to Tylodorus and shows similarity in several characters, except for the four prominent labial lobes and lateral field commencing at the base of the lip region. Tylodorus fisheri, sp. nov., collected from Eucalyptus forest in South Australia is described. It differs from T. acuminatus in that the labial disc is less prominent, the vulva more anteriorly situated, the tail longer and much more filiform, and the stylet and total nematode are longer.

Authors: Roth LM
Published: April 2005

Diagnostic characters are given for the ovoviviparous cockroach genus Laxta Walker, which is most closely related to Neolaxta Mackerras. The genus is principally Australian, but two (unnamed) species occur in New Guinea. There are at least 13 Australian species, of which 11 new taxa are described. Laxta pallida (Brunner) is synonymised with L. granicollis (Brunner). A key is provided to distinguish the males.
Revision of the genera Gollumiella Hedqvist and Anorasema Boucek (Hymenoptera : Eucharitidae)
Authors: Heraty JM
Published: April 2005

Gollumiella Hedqvist (type species: G. longipetiolata Hedqvist, 1978) is resurrected from synonymy with Losbanus Ishii, and Losbanus (type species: L. uichancoi Ishii, 1932) is synonymised with Orasema Cameron. Gollumiella is revised and a key is provided to distinguish the six species in the Indo-Pacific region. Three new species of Gollumiella are described: G. guineensis (New Guinea), G. infuscata (Borneo) and G. neopetiolata (Borneo, New Guinea and the Philippines). New character states for Anorasema Boucek are presented and a new species, A. manii (India), is described. Phylogenetic relationships among Gollumiella, Anorasema and other Eucharitidae are discussed.
Three distinctive new genera of Australian Catantopine grasshoppers (Orthoptera : Acrididae)
Authors: Key KH L
Published: April 2005

Three distinctive new genera of Australian catantopine Acrididae, Scurra, Pyrgophistes, and Kakaduacris, with their type species, are described and figured. The first two are apparently monotypic, the third with at least two species. Scurra is fully winged in both sexes; Pyrgophistes has macropterous males and brachypterous to mesopterous females; and Kakaduacris is micropterous. The distribution of the type species is plotted on the basis of the available material and some features of the biology indicated.
A revision of the genus Diala (Gastropoda : Cerithioidea : Dialidae)
Authors: Ponder WF , de Keyzer R
Published: April 2005

The systematics and distributions of the Recent species of the cerithioidean genus Diala are described. These small marine gastropods are confined to the Indo-West Pacific. Most are very widespread and have protoconchs which suggest that they possess planktotrophic larvae. Of the 30 available names, seven [D. semistriata (Philippi), D. albugo (Watson), D. suturalis (Adams), D. sulctfera Adams, D. sulcifera scobina (Laseron), D. sulcifera martensi (Issel) and D. lirulata Thiele] are recognised as valid, and one species (D. megapicalis, sp. nov.), from southern and western Australia, is described as new. All taxa are variable in shell characters such as colour pattern and size. An annotated list of all taxa originally described as Diala is provided.
Pseudocaeciliidae (Insecta : Psocoptera) from West Malaysia

The Pseudocaeciliidae of West Malaysia are reviewed, and 27 new species, belonging to five genera, Lobocaecilius Lee & Thornton (5 new species), Allocaecilius Lee & Thornton (2), Pseudocaecilius Enderlein (3), Heterocaecilius Lee & Thornton (10), and Pseudoscottiella Badonnel (7), are described. Pseudoscottiella, one of two pseudocaeciliid genera with a 2-branched media in the fore wing, is recorded from Malaysia for the first time. The male of Heterocaecilius longipenna Lee & Thornton is described and compared with two specimens of a closely related but yet unnamed species. Additional information on Heterocaecilius kobus Lee & Thornton is provided, and keys to species of all the above genera from West Malaysia given.
Revision of Vercoia Baker (Crustacea : Decopoda : Crangonidae)
Authors: Duris Z
Published: April 2005

Until recently, the rare crangonid genus Vercoia had been known from three specimens of the only species, V. gibbosa Baker, 1904, collected from South Australia and the Marshall Is. Additional records of three further specimens from South Australia and Queensland are provided in this study, as well as a redescription of the species, based on the holotype and four other specimens. Only females and juveniles of this species are known. The immature females differ from the ovigerous ones in the development of median-sternal structures on the thorax and abdomen. A second species, V. socotrana, sp. nov., based on a single ovigerous female from off Socotra I., north-western Indian Ocean, is described. It may be easily distinguished from the type species by the presence of an extremely broad merus on the second pereiopod.

A higher classification of the Australian Acridoidea (Orthoptera). II.* Subfamily Catantopinae
Authors: Key KHL , Colless DH
Published: April 2005

A classification of the Australian Acridoidea referable to the subfamily Catantopinae was undertaken within the framework proposed in Part I of this series. Five tribes are recognised: three very small, endemic, new ones; the non-endemic Cyrtacanthacridini, with very limited Australian representation; and the non-endemic Catantopini, with 22 subtribes, comprising 95% of the genera of Australian Catantopinae.*Part I, Invertebr. Taxon., 1992, 6, 547-51.
Two new genera of marine isopod crustaceans (Flabellifera : Sphaeromatidae) from southern Australia, with a reappraisal of the Sphaeromatidae
Authors: Bruce NL
Published: April 2005

Two new genera, Juletta and Margueritta, and the species Juletta mirandae, sp. nov., J. fika, sp. nov., and Margueritta sylviae, sp. nov. are described. The genera are both characterised by having a unicuspidate mandible incisor, both mandibles lacking a lacinia mobilis, medial lobe of maxillule with three spines, pleopods 1 operculate, pleonite 1 free and pleonites 3–6 indistinguishably fused to telson. Margueritta can readily be distinguished from Juletta by the presence of a pleotelsonic foramen and the lack of a proximal lobe on the palm of pereopods 2 and 3. Both genera are recorded from the intertidal or shallow subtidal zones (25 m), and are recorded from eastern Tasmania, Victoria, South Australia (Juletta) and southern Western Australia (Juletta and Margueritta). The distinctive mouthpart morphology of these genera led to a reappraisal of the mouthpart morphology of the constituent subfamilies of the Sphaeromatidae. It is principally mouthpart characters that are used to distinguish the newly redefined and elevated families Ancinidae Dana, 1852, and Tecticipitidae Iverson, 1982 from the Sphaerornatidae. The Sphaeromatidae are similarly rediagnosed with a more restrictive diagnosis. A synoptic list and key to the families of Flabellifera are given.
Troglobitic millipedes (Diplopoda : Paradoxosomatidae) from semi-arid Cape Range, Western Australia: Systematics and biology
Authors: Humphreys WF , Shear WA
Published: April 2005

Paradoxosomatid millipedes are an important component of the rich troglobitic fauna of the semi-arid tropical Cape Range, Western Australia. They are found in at least 55 of the 282 caves known from Cape Range covering >500 km². The millipedes occur in dense populations only in areas of high relative humidity and organic carbon content. They appear to be opportunistic and are able to grow and breed rapidly on the intermittently available patches of organic matter washed into the caves by unpredictable rainfall. A new genus of paradoxosomatid millipedes (Stygiochiropus, gen. nov.), comprising three species (S. communis, sp. nov., S. sympatricus, sp. nov., and S. isolatus, sp. nov.) is described from the caves. A key is provided for males, but females cannot be identified. The only widespread species (S. communis) separates into three provinces between which there are many fixed allelic differences, as determined by allozyme electrophoresis. Although these genetic provinces are separated by deep gorges that cut through the cavernous limestone into the underlying non-cavernous strata, the millipede populations cannot be separated using morphological criteria. The affinities of the millipedes are unknown, but they are part of a rich community of troglobites (>26 species) of which many species have affinities with the northern wet tropical forest fauna, rather than with the current semi-arid fauna.
Myrmecolacidae (Strepsiptera) from Australia
Authors: Kathirithamby J
Published: April 2005

Five new myrmecolacid species (Lychnocolax drysdalensis, L. maxillaris, Myrmecolax blfurcatus, Stichotremba kuranda and S. webbiense) are described from Australia. Five further species previously described from Malaysia, New Guinea and the Philippines are also recorded from Australia. Keys to the genera of Myrmecolacidae and to the Australian species are provided.
Classification, relationships and distribution of the genera of Heleini (Coleoptera : Tenebrionidae)
Authors: Matthews EG
Published: April 2005

The tribe Heleini is redefined to exclude the genera Lepispilus Westwood, 1841, and Leaus Matthews & Lawrence, 1992, which become incertae sedis within the subfamily Tenebrioninae . Four generic names are synonymised as follows: Barytipha Pascoe, 1869, and Pezohelaeus Gebien, 1920, with Pterohelaeus Brême, 1842; Euhelaeus Gebien, 1920, with Emcephalus Kirby, 1828; and Saragella Carter, 1937, with Dysarchus Pascoe, 1866. The genus Saragus Erichson, 1842, is resurrected as separate from Celibe Boisduval, 1835, with which it had been confused, and two new genera (Boreosaragus and Cillibus) are proposed for other species formerly in Celibe, bringing the total to 14 genera in the tribe, which is distributed in Australia, New Zealand, New Guinea and Seram. A tentative phylogeny is proposed for the genera, the constituent species are either mentioned or reference is made to a former checklist, and the Australian distribution of all but two genera is plotted. Hypotheses are put forward on evolutionary trends and the past history of the tribe. The 27 new combinations proposed are listed in Appendices I and II at the end of the paper.
New genera of Catantopini in the subtribe Coryphistina (Orthoptera : Acrididae)

Published: April 2005

A synoptic list is given of all the ascaridoid nematodes known from fish hosts, totalling over 500 binomial combinations. The checklist consists of four lists: A, recognisable names; B, names based on larval forms; C, incertae sedis; and D, species inquirendae and nomina dubia. These lists total 357 names. Of these names, fewer than half (45%) fall into the category of recognisable names. A further list of host names, cross-referenced to the checklist, is also provided.
Review of the family Janiridae (Crustacea : Isopoda : Asellota)
Authors: Wilson GDF , Wagele JW
Published: April 2005

The family Janiridae is reviewed, primarily using the published literature, as a step for revising the systematics of the Asellota. The history of janirid taxonomy is reviewed, and all taxa that have been attributed to the family are listed and discussed. A new composition for the family is provided with synonymies and references to all genera. The genera included in the Janiridae are: Austrofilius Hodgson, Caecianiropsis Menzies & Petit, Caecijaera Menzies, Carpias Richardson, Ectias Richardson, Hawaianira Miller, Heterias Richardson, Iais Bovallius, Ianiropsis Sars, Iathrippa Bovallius, Jaera Leach, Janaira Moreira & Pires, Janira Leach, Janiralata Menzies, Janthura Wolff, Mackinia Matsumoto, Microjaera Bocquet & Levi, Microjanira Schiecke & Fresi, Neojaera Nordenstam, Protocharon Chappuis, Delamare-Deboutteville & Paulian. A key is provided for identification of genera belonging to the Janiridae and related families. Generic compositions are revised where necessary, and diagnoses, lists of species and most references are provided for each genus discussed. The composition of the Microparasellidae is discussed and a provisional diagnosis is given. The Microparasellidae is limited to the following genera: Angeliera Chappuis & Delamare, Microcharon Karaman, Microparasellus Karaman, Paracharon Coineau. Some genera are excluded from the Janiridae and temporarily left as family incertae sedis: Tole Ortmann (= Iolella Richardson), Jaerella Richardson, Rhacura Richardson, Trichopleon Beddard, Xostylus Menzies.
Sandy beach meiofauna of eastern Australia (southern Queensland and New South Wales). II. Luriculus australiensis, gen. et. sp. nov. (Luridae : Dalyelliida : Platyhelminthes)
Authors: Faubel A , Rohde K , Watson NA
Published: April 2005

Luriculus australiensis, gen. et sp, nov., from a sandy, exposed ocean beach at Arrawarra Headland, north of Coffs Harbour, NSW, Australia, is described on the basis of light and electron microscopic investigations. The establishment of the new genus Luriculus is based on the presence of germovitellaria, rather than discrete organs. Lurus castor Sterrer & Rieger, 1990, Lurus tyndareus Sterrer & Rieger, 1990, and Lurus minos Sterrer, 1992, are transferred to this genus.
Revision of the Australian leafhopper genus Euleimonios Kirkaldy (Hemiptera : Cicadellidae : Deltocephalinae)

Published: April 2005

The Australian leafhopper genus Euleimonios Kirkaldy (Hemiptera : Cicadellidae : Deltocephalinae) is revised and transferred to the tribe Paralimnini. E. flavidiventris (Stål) is redescribed and seven new species (E. sinuatus, E. magnus, E. rosifrons, E. kirkaldyi, E. montanus, E. uniformis and E. truculentus) are described. Deltocephalus dedarensis Evans is transferred to Euleimonios and redescribed. A key to males is provided.
Three new species of Australian 'golden blowflies' (Diptera : Calliphoridae : Calliphora), with a key to described species
Authors: Norris KR
Published: April 2005

Calliphora maritima, C. forresri and C. gilesi from southern Australia are described as new. They belong to a group of blowflies that have the abdominal dorsum mottled gold, or checkering from gold to olive or brown, according to the angle of viewing, and have legs chiefly yellow to brown, but never entirely black. These 'golden blowflies' are readily recognised as such, even in the field, but, pending refinement of taxonomic subdivision, are here assigned only to the broad genus Calliphora Robineau-Desvoidy. A key is given for the identification of described species of 'golden blowflies'.
The final-stage larvae of Brunettia (Diptera: Psychodidae: Psychodinae) and their evolutionary significance
Authors: Duckhouse DA
Published: April 2005

The semi-terrestrial final instar larva of the Australian species Brunettia (Atrichobrunettia) scitula Duckhouse is described using revised chaetotaxic terminology, as a basis for broader systematic studies. That of Brunettia (Mirousiella) angustipennis (Tonnoir), the only other Brunettia larva known, is redescribed, compared with that of B. scitula and found to be different enough to support its present classification in a separate subgenus. The pupae of both species remain largely enclosed in the last larval skin, the protected parts being unsclerotised and the whole body having reduced sensory setae.Examination of outgroups shows that the stem-form of the Psychodinae was most probably terrestrial. From here the general trend has been towards marginal and finally aquatic habits. Earlier genealogical hypotheses are elaborated along these lines by adding subsidiary hypotheses, including Clytocerus Eaton as a basal offshoot of this subfamily. Brunettia resembles Mormia Enderlein in both larva and adult. It is also very like Clytocerus and Nemoneura Tonnoir in its larva, but not its adult. These incongruences are discussed. The assertions that Brunettia and Mormia share very few characters and do not belong in the same tribe, and that Mormia belongs instead with Telmatoscopus Eaton and Panimerus Eaton in the Paramormiini, are tested, and it is shown that there is no evidence for a paramormiine relationship. It is instead confirmed that Mormia belongs with Brunettia in the same tribe, Mormiini.

The systematics of the spider family Nicodamidae ( Araneae : Amaurpbioidea)
Authors: Harvey MS
Published: April 2005

A review of the spider family Nicodamidae reveals two subfamilies, Nicodaminae and Megadictyninae, with 29 species. The Nicodaminae contains Nicodamus Simon and six new genera, Ambicodamus, Dimidamus, Durodamus, Litodamus, Novodamus and Oncodamus, from Australia, Papua New Guinea and Irian Jaya. Nicodamus is restricted to N. peregrinus (Walckenaer) and N. mainae, sp. nov.; N. peregrinus is treated as a senior synonym of Theridium semiflavum L. Koch, Centropelma bicolor L. Koch and Ozaleus tarandus Thorell. Ozaleus Thorell is confirmed as a junior synonym of Nicodamus by designation of a lectotype for the type species, 0. tarandus. Durodamus contains one species: D. yeni, sp. nov. (type species). Ambicodamus contains 11 species: A. marae, sp. nov. (type species), A. audax, sp. nov., A. crinitus (L. Koch), comb. nov., A. dale, sp. nov., A. darlingtoni, sp. nov., A. emu, sp. nov., A. kochi, sp. nov., A. leei, sp. nov., A. sororius, sp. nov., A. southwelli, sp. nov. and A. urbanus, sp. nov. Litodamus contains three species: L. hickmani, sp. nov. (type species), L. olga sp. nov. and L. collinus, sp. nov. Dimidamus contains six species: D. dimidiatus (Simon), comb. nov. (type species), D. simoni, sp. nov., D. leopoldi (Roewer), comb. nov., D. arau, sp. nov., D. sero, sp. nov. and D. enaro, sp. nov. Novodamus contains two species: N. nodatus (Karsch), comb. nov. (type species) and N. supernus, sp. nov.; Linyphia meianozantha Urquhart is treated as a junior synonym of N. nodatus. Oncodamus contains two species: 0. bidens (Karsch), comb. nov. (type species) and 0. decipiens, sp. nov. The Megadictyninae, stat. nov., contains two genera from New Zealand, Megadictyna Dahl with M. thilenii Dahl and Forstertyna, gen. nov. with F. marplesi (Forster), comb. nov. Cladistic analysis confirms the division of the family into two subfamilies, and recognises several subgroups within the Nicodaminae: Nicodamus + Durodamus, Ambicodamus + Litodamus, and Novodamus + Oncodamus.

The Gastrocoptinae of Australia (Gastropoda : Pulmonata : Pupilloidae): Systematics, distribution and origin
Authors: Pokryszko BM
Published: April 2005

The Gastrocoptinae of Australia are revised on the basis of over 13 000 specimens from nearly 600 localities. Of 23 nominal species 12 are synonymised; Gastrocopta stupefaciens, sp. nov., and G. solemorum, sp. nov., are described, making a total of 13 species. A key to the species is provided. Pumilicopta Solem, 1989 is reduced to subgeneric rank. Eleven of 13 species are endemic to Australia, one to Australia and New Guinea, and one is recorded from Australia and some Pacific islands. The gastrocoptines inhabit only coastal areas and the 'Red Centre'; only three species are exclusively southern. Relationships with extralimital taxa, based on derived characters of apertural barriers and shell sculpture, indicate that the gastrocoptines colonised Australia at least four times from Asia and adjacent islands. The first immigration may have taken place in the mid-Miocene.
Observing spontaneous branch migration of Holliday junctions one step at a time
Authors: McKinney Sean A. , Freeman Alasdair D. J. , Lilley David M. J. , Ha Taekjip
Published: April 2005

Genetic recombination occurs between homologous DNA molecules via a four-way (Holliday) junction intermediate. This ancient and ubiquitous process is important for the repair of double-stranded breaks, the restart of stalled replication forks, and the creation of genetic diversity. Once formed, the four-way junction alone can undergo the stepwise exchange of base pairs known as spontaneous branch migration. Conventional ensemble assays, useful for finding average migration rates over long sequences, have been unable to examine the affect of sequence and structure on the migration process. Here, we present a single-molecule spontaneous branch migration assay with single-base pair resolution in a study of individual DNA junctions that can undergo one step of migration. Junctions exhibit markedly different dynamics of exchange between stacking conformers depending on the point of strand exchange, allowing the moment at which branch migration occurs to be detected. The free energy landscape of spontaneous branch migration is found to be highly nonuniform and governed by two types of sequence-dependent barriers, with unmediated local migration being up to 10 times more rapid than the previously deduced average rate.
Mutations in PTEN-induced putative kinase 1 associated with recessive parkinsonism have differential effects on protein stability

Published: April 2005

Several mutations in PTEN-induced putative kinase 1 (
PINK1
) gene have been reported to be associated with recessive parkinsonism. The encoded protein is predicted to be a Ser/Thr protein kinase targeted to mitochondria. In this study, we have investigated the effects of mutations on PINK1 kinase activity
in vitro
and on expression levels and localization in mammalian cells. We chose to examine two point mutations: G309D, which was originally reported to be stable and properly localized in cells and L347P, which is of interest because it is present at an appreciable carrier frequency in the Philippines. We were able to confirm kinase activity and produce artificial “kinase-dead” mutants that are stable but lack activity. The L347P mutation grossly destabilizes PINK1 and drastically reduces kinase activity, whereas G309D has much more modest effects on these parameters
in vitro
. This finding is in line with predictions based on homology modeling. We also examined the localization of PINK1 in transfected mammalian cells by using constructs that were tagged with myc or GFP at either end of the protein. These results show that PINK1 is processed at the N terminus in a manner consistent with mitochondrial import, but the mature protein also exists in the cytosol. The physiological relevance of this observation is not yet clear, but it implies that a portion of PINK1 may be exported after processing in the mitochondria.
Two essential but distinct functions of the mammalian abasic endonuclease
Authors: Izumi Tadahide , Brown David B. , Naidu C. V. , Bhakat Kishor K. , MacInnes Mark A. , Saito Hiroshi , Chen David J. , Mitra Sankar
Published: April 2005

The mammalian abasic endonuclease, APE1, has two distinct roles in the repair of oxidative DNA damage and in gene regulation. Here we show that both functions are essential for cell survival. Deletion of the
APE1
gene causes embryonic lethality in mice, and no nullizygous embryo fibroblasts have been isolated. We have now established nullizygous embryo fibroblast lines from APE1
–/–
mouse embryos that are transgenic with the “floxed” human APE1 (
hAPE1
) gene. Removal of
hAPE1
by Cre expression through nuclear microinjection elicited apoptosis in these cells within 24 h, which was blocked by coinjection of the wild-type
hAPE1
gene. In contrast, mutant hAPE1 alleles, lacking either the DNA repair or acetylation-mediated gene regulatory function, could not prevent apoptosis, although the combination of these two mutants complemented APE deficiency induced by Cre. These results indicate that distinct and separable functions of APE1 are both essential for mammalian cells even
in vitro
and provide the evidence that mammalian cells, unlike yeast or
Escherichia coli
, absolutely require APE for survival, presumably to protect against spontaneous oxidative DNA damage.
Are there functional consequences of a reduction in selenium intake in UK subjects?
Authors: Jackson Malcolm J. , Dillon Stephanie A. , Broome Caroline S. , McArdle Anne , Hart C. Anthony , McArdle Francis
Published: April 2005

Dietary Se levels in the UK have fallen over the last 20 years and recent surveys indicate that average Se intakes are 30–40 μg/d, which is well below the current UK reference nutrient intake for adult men (75 μg/d) or women (60 μg/d). Functional consequences of this decline have not been recognised, although epidemiological data suggest it may contribute to increased risk of infections and incidence of some cancers. Previous data have indicated that biochemical changes in Se-dependent proteins occur in otherwise healthy UK subjects given small Se supplements. The current studies have focused on the effect of small Se supplements on the immune response since there is evidence of specific interactions between Se intake and viral replication, and since the potential anti-cancer effects of Se may be mediated by non-antioxidant effects of Se such as changes in immune function. Data indicate that subjects given small Se supplements (50 or 100 μg Se/d) have changes in the activity of Se-dependent enzymes and evidence of improved immune function and clearance of an administered live attenuated virus in the form of poliovirus vaccine. Responses of individual subjects to Se supplements are variable, and current work is evaluating potential explanations for this variability, including genetic variability and pre-existing Se status.

Hypertension affects nearly 20% of the population in Western countries and strongly increases the risk for cardiovascular diseases. In the pathogenesis of hypertension, the vasoactive peptide of the renin-angiotensin system, angiotensin II and its G protein–coupled receptors (GPCRs), play a crucial role by eliciting reactive oxygen species (ROS) and mediating vessel contractility. Here we show that mice lacking the GPCR-activated phosphoinositide 3-kinase (PI3K)γ are protected from hypertension that is induced by administration of angiotensin II in vivo. PI3Kγ was found to play a role in angiotensin II–evoked smooth muscle contraction in two crucial, distinct signaling pathways. In response to angiotensin II, PI3Kγ was required for the activation of Rac and the subsequent triggering of ROS production. Conversely, PI3Kγ was necessary to activate protein kinase B/Akt, which, in turn, enhanced L-type Ca2+ channel–mediated extracellular Ca2+ entry. These data indicate that PI3Kγ is a key transducer of the intracellular signals that are evoked by angiotensin II and suggest that blocking PI3Kγ function might be exploited to improve therapeutic intervention on hypertension.
Specification of germ cell fate in mice

Published: April 2005

An early fundamental event during development is the segregation of germ cells from somatic cells. In many organisms, this is accomplished by the inheritance of preformed germ plasm, which apparently imposes transcriptional repression to prevent somatic cell fate. However, in mammals, pluripotent epiblast cells acquire germ cell fate in response to signalling molecules. We have used single cell analysis to study how epiblast cells acquire germ cell competence and undergo specification. Germ cell competent cells expressFragilisand initially progress towards a somatic mesodermal fate. However, a subset of these cells, the future primordial germ cells (PGCs), then shows rapid upregulation ofFragiliswith concomitant transcriptional repression of a number of genes, includingHoxandSmadgenes. This repression may be a key event associated with germ cell specification. Furthermore, PGCs expressStellaand other genes, such asOct–4that are associated with pluripotency. While these molecules are also detected in mature oocytes as maternally inherited factors, their early role is to regulate development and maintain pluripotency, and they do not serve the role of classical germline determinants.
Surgical uterine devascularization for placenta accreta: immediate and long‐term follow‐up
Authors: Verspyck Eric , Resch Benoit , Sergent Fabrice , Marpeau Loïc
Published: April 2005

Background.  To report immediate and long‐term outcome in patients with surgical  uterine devascularization for placenta accreta.

Methods.  Six patients with placenta accreta were treated conservatively during a cesarean section by a bilateral uterine and ovarian surgical devascularization procedure. Menstrual flow, imaging monitoring and further pregnancy were retrospectively reported.

Results.  Blood transfusion was necessary in five cases and a hysterectomy was performed in one patient with placenta previa accreta. All patients resumed menstruation without oral contraception but one of them reported temporary clinical symptoms of estrogen insufficiency. A chronic placental retention occurred in three patients with incomplete placenta removal. One patient with both bilateral uterine and ovarian arterial ligations had a subsequent pregnancy complicated by a recurrent placenta accreta that was subsequently treated conservatively.

Conclusions.  Surgical uterine devascularization for placenta accreta may be useful for uterine conservation. However, reproductive capacity may be altered by placental chronic retention and further pregnancies may be complicated by recurrent placenta accreta.
