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.

A reassessment of the referral of Sea Turtle skulls to Osteopygis(Late Cretaceous, New Jersey, USA)

Journal Article Parham, James F. - Journal of Vertebrate Paleontology

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 »« less

Structural-group composition of organosulphur compounds of gas condensate from the Urtabulak deposit of Uzbekistan

Journal Article Agadzhanova, N.V. ; Aliyeva, R.B. ; Lyapina, N.K. ; ... - Pet. Chem. USSR (Engl. Transl.); (United States)

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.

Lung exposure from inhalation of radon progeny: Calculated from in vivo measurements of {sup 210}Pb in the skull

Journal Article Laurer, G.R. ; Cohen, N. ; Estrada, J.J.S. - Health Physics

To calculate the radiation dose to the lungs from the inhalation of radon and its short-lived progeny, an accurate estimate of cumulative exposure is necessary. In this preliminary study, the content of {sup 210}Pb in the skeleton is used to obtain a measure of integrated exposure to the lungs of people living in homes with above average concentrations of radon. Measurements of skeletal {sup 210}Pb made in vivo allow the exposed individuals to become, in effect, their own samplers and dosimeters through the normal physical and physiological processes of inhalation, deposition, and retention. {sup 210}Pb measurements have been made onmore »« less

Neural differentiation of adipose-derived stem cells isolated from GFP transgenic mice

Journal Article Fujimura, Juri ; Department of Pediatrics, Nippon Medical School, Tokyo ; E-mail: juri-f@nms.ac.jp ; ... - Biochemical and Biophysical Research Communications

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 »« less

Morphological, molecular and functional differences of adult bone marrow- and adipose-derived stem cells isolated from rats of different ages

Journal Article Mantovani, Cristina ; Department of Integrative Medical Biology and Surgical and Perioperative Science, Umea University, Umea ; Department of Surgical and Perioperative Science, Umea University, Umea ; ... - Experimental Cell Research

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 »« less
