Noducyclamides A1–A4, B1, and B2 from the Cyanobacterium <i>Nodularia</i> sp. NIES-3585
No full textA chemical investigation of the hydrophilic fraction
of a cultured Nodularia sp. (NIES-3585) afforded
six new cyclic lipopeptides,
noducyclamides A1–A4 (1–4)
containing 10 amino acid residues and dodecapeptides noducyclamides
B1 and B2 (5 and 6). The planar structures
of these lipopeptides were elucidated based on the combination of
HRMS and 1D and 2D NMR spectroscopic data analyses. These peptides
are structurally analogous to laxaphycins and contain the nonproteinogenic
amino acids 3-hydroxyvaline and 3-hydroxyleucine and a β-amino
decanoic acid residue. The absolute configurations of the noducyclamides
(1–6) were determined by acid hydrolysis,
followed by advanced Marfey’s analysis. Noducyclamide B1 (5) showed cytotoxic activities against MCF7 breast cancer
cell lines with an IC50 value of 3.0 μg/mL (2.2 μM)

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
Thermal Process of Rock Crystal: Cause of Infrared Absorption Band at 3585 cm<sup>−1</sup>
No full textSynthetic rock crystals often show a typical infrared (IR) absorption band at 3585 cm−1. However, the authors recently found this band in a natural rock crystal with blue coating. The origin of this IR band is controversial as yet. In this paper, the infrared spectra of several natural and synthetic rock crystal samples which were heated to 673 K and 1073 K were measured after these samples returned to room temperature. Comparing the infrared spectra of samples before and after heating, we found the absorption band at 3585 cm−1 was induced by the thermal process, which indicates that this band cannot be used as diagnostic evidence for synthetic rock crystal alone. In addition, the LiOH bands decreased while AlOH bands increased upon thermal processing. And the negative correlation between the LiOH bands and the 3585 cm−1 band was also distinct. The above results reveal that the thermal process destroyed the LiOH defects, leading to the formation of a new AlLi defect. And the isolated OH− defect inside dislocations generated upon thermal processing is considered to be the exact cause of the 3585 cm−1 band
