Characterization of diagenetic fluids at ODP Site 103-639
No full textSite 639, drilled during Leg 103 of the Ocean Drilling Program, penetrated an Upper Jurassic to Lower Cretaceous carbonate platform on a tilted fault block along the Galicia margin off the northwest Iberian Peninsula. The carbonate platform is composed primarily of a sequence of dolomite overlying limestone. Samples were analyzed for mineral chemistry, stable isotope geochemistry, fluid inclusion microthermometry, and volatile contents and by dolomite pyrolysis mass spectrometry for trace sulfate minerals. The dolomite recovered from the Galicia margin at Site 639 formed during shallow burial from sulfate-bearing, hypersaline brines at slightly elevated temperatures. The light oxygen isotopic signatures of the dolomite are interpreted as the result of the evaporative loop and slightly elevated temperatures during dolomite formation or from reequilibration at higher temperatures during deeper burial. The hypersalinity is interpreted to be associated with a nearby, shallow restricted basin that formed during rifting of the Iberian margin from Newfoundland. The dolomitization of the platform is therefore a by-product of the rifting
Chemical composition of rhyolites of ODP Site 103-639
No full textHoles 639E and 639F were drilled along the western slope of a tilted fault block in an attempt to recover complete syn- and pre-rift stratigraphic sections and continental basement. Both holes ended in an apparent talus pile or conglomerate that includes cobbles of altered rhyolitic rock. Three small pieces of rhyolite (comprising about 20 cm of sample) were recovered from the bottoms of Holes 639E and 639F in the core catchers of the deepest cores. This note presents geochemical data from these rhyolitic rocks. Also recovered were quartz sandstones, graywackes, metasandstones, and quartz breccias. This assemblage of continentally derived 'basement' material was overlain by mudstones, limestones, and crystalline dolomites (see 'Site 639' chapter; Shipboard Scientific Party, 1987, doi:10.2973/odp.proc.ir.103.110.1987)

Abstract 639: Acute promyelocytic leukemia
No full textAbstract Introduction: Acute Promyelocytic Leukemia (APL) accounts for 10%-15% of all acute myeloid leukemia's. The use of All-Trans Retinoic Acid/ Arsenic trioxide (ATRA/ATO) in the treatment regimens of low to intermediate-risk patients has led to remarkable cure rates (~80%). However, treatment guidelines of high-risk patients (WBC count≥ 10 x 109/L) remain unclear and these patients are at an increased risk of relapse. Design: Due to ambiguous treatment guidelines for high-risk APL patients as well as limited options for patients with arsenic resistant disease we sought to analyze clinical outcomes in this subset of patients. We conducted a literature search through Pubmed, EBSCO, and JSTOR to identify original articles that evaluated treatment protocols as well as outcomes for high-risk/refractory APL patients. We also evaluated the literature for clinical data involving patients who had arsenic resistant APL. Only relevant articles from 2000 to 2019 were included. Clinical trials where patients did not receive ATRA/ATO treatment were excluded. High risk patients have an increased mortality and decreased overall survival compared to intermediate and low risk patients. Although early death resulting from bleeding complications remains an important clinical hindrance, cases of arsenic resistant disease are becoming more prevalent. Resistant/refractory APL is a rare occurrence; however, no effective treatment exists to overcome resistance in this subset of patients. Of particular interest is the identification of variant translocations in APL; those that differ from the classical PML-RARA (~95%). 12 non-characteristic rearrangements have so far been described; of these, the ZBTB16-RARA and STAT5b-RARA are the most common variants. Both ZBTB16-RARA & STAT5b-RARA are insensitive to ATRA/ATO combination therapy, leaving these patients with limited options. Clinical outcomes have recently been described in a subset of 13 patients with arsenic resistant disease. Of these 13 patients with arsenic resistant disease, 11 eventually died. Mutations in a particular region of the PML protein have been shown to mediate arsenic resistant disease in both in vitro and in vivo models, suggesting a potential benefit of molecular screening to improve clinical outcomes. Neither ATO nor cytotoxic chemotherapy was successful in inducing remissions in this particular subset of patients. Conclusion: Well-defined treatment guidelines in high-risk APL and the need for alternative agents in patients resistant to ATO therapy are needed to improve clinical efficacy and outcomes. 1.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
