Title: A reassessment of the referral of an isolated skull from the latecretaceous of Uzbekistan to the stem-testudinoid turtlelindholmemys

Abstract

A fossil turtle skull (ZISP PH 1/17) from the LateCretaceous (upper Turonian, Bissekty Formation) of Dzharakuduk(Uzbekistan, Asia) was used to score the skull characters for the genusLindholmemys (a stem testudinoid) in a recent phylogenetic analysis. Adescription of ZISP PH 1/17 and a new cladistic analysis reveals nocharacters to support its referral to Lindholmemys elegans or to thestem-testudinoid lineage. ZISP PH 1/17 is very similar to North AmericanAdocus, differing mainly in characters of the upper jaw. Therefore, wehypothesize that ZISP PH 1/17 is the skull of either Shachemysancestralis or "Adocus" aksary, adocid shell taxa from Dzharakuduk.Pending additional discoveries and description of turtles fromDzharakuduk, we refer ZISP PH 1/17 to Adocidae, gen. et sp.indet.

  • Specimens referred to Osteopygis (Late Cretaceous-Paleocene,North America) represent a chimera, a polyphyletic mixture of taxa. Theholotype of Osteopygis (AMNH 1485) and more complete referred postcranialspecimens resemble non-marine stem cryptodires ("macrobaenids"). Becausethe skull material historically referredto Osteopygis sharessynapomorphies with cheloniid sea turtles, all current workers acceptOsteopygis as a stem-cheloniid sea turtle. Multiple lines of evidencecombine to support the hypothesis that sea turtle cranial material is notattributable to Osteopygis. These lines of evidence include: phylogenetichypotheses of character evolution, the tenuous historical attribution ofspecimens, and the taphonomy of the Hornerstown Formation. Thename-bearing Osteopygis material and referred postcrania are bestconsidered Eucryptodira incertae sedis (cf.more » "Macrobaenidae"). The cranialspecimens formerly assigned to the Osteopyginae now are restricted to theclade Euclastes and those referred to Osteopygis emarginatus are herereferred to Euclastes wielandi (comb. nov.). The 'decapitation' ofOsteopygis reconciles morphological trends within stemcheloniids.« less
  • Taking advantage of homogeneously marked cells from green fluorescent protein (GFP) transgenic mice, we have recently reported that adipose-derived stromal cells (ASCs) could differentiate into mesenchymal lineages in vitro. In this study, we performed neural induction using ASCs from GFP transgenic mice and were able to induce these ASCs into neuronal and glial cell lineages. Most of the neurally induced cells showed bipolar or multipolar appearance morphologically and expressed neuronal markers. Electron microscopy revealed their neuronal morphology. Some cells also showed glial phenotypes, as shown immunocytochemically. The present study clearly shows that ASCs derived from GFP transgenic mice differentiate intomore » neural lineages in vitro, suggesting that these cells might provide an ideal source for further neural stem cell research with possible therapeutic application for neurological disorders.« less
  • Adult mesenchymal stem cells have self-renewal and multiple differentiation potentials, and play important roles in regenerative medicine. However, their use may be limited by senescence or age of the donor, leading to changes in stem cell functionality. We investigated morphological, molecular and functional differences between bone marrow-derived (MSC) and adipose-derived (ASC) stem cells isolated from neonatal, young and old rats compared to Schwann cells from the same animals. Immunocytochemistry, RT-PCR, proliferation assays, western blotting and transmission electron microscopy were used to investigate expression of senescence markers. Undifferentiated and differentiated ASC and MSC from animals of different ages expressed Notch-2 atmore » similar levels; protein-38 and protein-53 were present in all groups of cells with a trend towards increased levels in cells from older animals compared to those from neonatal and young rats. Following co-culture with adult neuronal cells, dMSC and dASC from animals of all ages elicited robust neurite outgrowth. Mitotracker{sup Registered-Sign} staining was consistent with ultrastructural changes seen in the mitochondria of cells from old rats, indicative of senescence. In conclusion, this study showed that although the cells from aged animals expressed markers of senescence, aged MSC and ASC differentiated into SC-like cells still retain potential to support axon regeneration. -- Highlights: Black-Right-Pointing-Pointer Aged MSC and ASC differentiated into Schwann-like cells support axon regeneration. Black-Right-Pointing-Pointer p53 expression does not appreciably influence the biology of Schwann or stem cells. Black-Right-Pointing-Pointer Notch 2 expression was similar in cells derived from animals of different ages. Black-Right-Pointing-Pointer Proliferation rates of dMSC varied little over time or with animal age.« less
  • Concentrates of organosulphur compounds were isolated for the first time from the gas condensates of the Urtabulak deposit by extraction using 87 and 91% sulphuric acid. The structural-group composition of sulphides and thiophenes in the condensate were examined. The sulphides among the organosulphur compounds consist mainly of thiamono-, thiabicyclo-paraffins and dialkylsulphides. The thiophenes include alkylsubstituted thiophenes and benzothiophenes.
