No full textOdaginiceps xamaneki Fiers, 1995 Odaginiceps Fiers, 1995 in Gómez and Morales-Serna (2014, Appendix 2: 121) Locality Off Campeche State; 18.7525° N, 92.5028° W; 16 m depth. Material examined One adult female, dissected (EMUCOP-07); one adult male dissected (EMUCOP-08); one adult male, one adult female and one male C IV in alcohol (EMUCOP-09). Remarks The genus Odaginiceps was created by Fiers (1995) to accommodate O. clarkae Fiers, 1995 as the type species, O. elegantissima and O. xamaneki. At present the genus is composed of the preceding species and O. immanis Fiers and De Troch, 2000, and O. korykosensis Karaytug, Sak and Alper, 2010. Odaginiceps elegantissima has been reported from Bermuda only. The records of O. elegantissima presented herein extend its distribution range to the southern region of the Gulf of Mexico and to the Tropical Eastern Pacific. The species shows preference for sandy-silt sediments of relatively shallow systems (up to 16 m depth) (Fiers 1995; Gómez-Noguera and Hendrickx 1997). Odaginiceps xamaneki was originally described by Fiers (1995) from samples collected from the western region of the Yucatan continental shelf. The record of this species presented herein extends its distribution range to the coasts of Campeche State. The species has been found at depths of 40.9 m (Fiers 1995) and 16 m (present study), and shows preference for sandy and well-oxygenated sediments.Published as part of Gómez, Samuel & Morales-Serna, Francisco Neptali, 2015, On a small collection of Tetragonicipitidae Lang, 1944 (Copepoda: Harpacticoida) from Mexico: new records and new species, pp. 2827-2868 in Journal of Natural History 49 (45) on page 2830, DOI: 10.1080/00222933.2015.1038329, http://zenodo.org/record/400226

No full textGodianiceps maya Fiers, 1995 Locality Off Campeche State; 18.8394°N, 92.2777°W; 18 m depth. Material examined One adult male, dissected (EMUCOP-04); one adult male in alcohol (EMUCOP-05). Remarks The genus Godianiceps was created by Fiers (1995) for a new tetragonicipitid species, G. maya, found in samples from Nichupté lagoon (Quintana Roo, Mexico). The species has also been reported by Suárez-Morales et al. (2009) from the southwest coast of the Gulf of Mexico. So far, G. maya has been found in shallow waters up to 3 m in depth. The specimens reported here were found at a depth of 18 m. The species shows preference for sandy and well-oxygenated shallow habitats.Published as part of Gómez, Samuel & Morales-Serna, Francisco Neptali, 2015, On a small collection of Tetragonicipitidae Lang, 1944 (Copepoda: Harpacticoida) from Mexico: new records and new species, pp. 2827-2868 in Journal of Natural History 49 (45) on page 2829, DOI: 10.1080/00222933.2015.1038329, http://zenodo.org/record/400226
A simian virus 40-encoded protein of M r 74,000 daltons is structurally related to the capsid proteins of the virus
No full textKrippl B, Dreiseikelmann B, Werchau H. A simian virus 40-encoded protein of M r 74,000 daltons is structurally related to the capsid proteins of the virus. Journal of Cellular Biochemistry. 1983;22(4):197-207.We have demonstrated the synthesis of a 74,000-dalton protein (74K protein) in African green monkey kidney cells infected with simian virus (SV)40. The 74K protein was detected late during the lytic cycle. Its synthesis was inhibited by arabinosyl cytosine as was the synthesis of the capsid proteins. Monospecific antibodies raised against VP1 and VP3 precipitated the structural proteins and the 74K protein. The 74K protein was not found in purified virions. Tryptic peptide analysis demonstrated that the 74K protein shares methionine- and serine-containing peptides with VP1 and VP3 and thus is structurally related to the capsid proteins

Discovery of a new species of the genus Stygepactophanes from a groundwater-fed spring in southern France (Crustacea, Copepoda, Harpacticoida, Canthocamptidae)
No full textA new species of the genus Stygepactophanes Moeschler & Rouch, 1984 (Copepoda, Harpacticoida, Canthocamptidae) is established to accommodate a small canthocamptid population collected from a spring system in the “Parc du Mercantour”, Var catchment, southern France. The population analysed in the present study is defined by a set of morphological characters of the female, namely a very large maxilliped, a rudimentary mandibular palp, P1 with 3-segmented exopod and 2-segmented endopod, a falcate terminal claw of the P1 endopod, dorsal seta of caudal rami inserted on the inner margin, and anal operculum not overreaching the insertion of the caudal rami, thus supporting its assignment into the genus Stygepactophanes. The new species Stygepactophanes occitanus shows marked differences with the nominotypical species of the genus that was originally described by monotypy with the species Stygepactophanes jurassicus Moeschler & Rouch, 1984. The main diagnostic traits of S. jurassicus are the absence of the P5 and a falcate outer terminal claw of P1 endopod. Stygepactophanes jurassicus also shows a reduced armature of the antennal exopod, bearing one seta, 1-segmented P2–P4 endopods, a reduced armature of P2–P4 exopodal segments 3 (3,4,4 armature elements, respectively), P6 bearing only one long seta, a rounded short and smooth anal operculum. Conversely the female of S. occitanus Galassi & Fiers, sp. n. has a well-developed P5, with rudimentary intercoxal sclerite, together with a falcate outer terminal claw of P1 endopod, antennal exopod bearing two elements, P4 endopod 1-segmented versus 2-segmented in P2–P3, P2–P4 exopodal segment 3 with five armature elements, P6 with three setae of different lengths, rounded anal operculum, bearing 3–4 strong spinules.
According to our present knowledge, S. occitanus Galassi & Fiers, sp. n. is assigned to the genus Stygepactophanes as the most conservative solution, waiting for the male to be discovered. The genus Stygepactophanes represents a distinct lineage within the harpacticoid family Canthocamptidae that colonised southern European groundwater, the genus being known only from the saturated karst in Switzerland and a fissured saturated aquifer in southern France. Both species of the genus are stygobites and narrow endemics, the nominotypical species being known from the type locality Source de la Doux in Délemont (Switzerland), and S. occitanus Galassi & Fiers, sp. n. described herein from a spring system of the Var catchment (France)
