Lady Gaga, allt handlar om strategi? : En studie kring vem eller vilka personer och vilka faktorer som skapade superstjärnan Lady Gaga

De frågeställningar som jag har utgått från är vem eller vilka personer, och vilka andra faktorer skapade superstjärnan Lady Gaga? Har Lady Gaga blivit framgångsrik på egen hand eller huvudsakligen som ett resultat av andra personer och deras inverkan? Syftet är att analysera bakgrunden till Lady Gagas enorma succé och utforska möjliga orsaker och förklaringar till den, för att sedan kunna använda och föra vidare kunskapen om dessa framgångsstrategier i musikbranschen. Jag har använt mig av kvalitativa intervjuer med fallstudien som metod. Intervjuerna är gjorda i New York, USA och omfattar inflytelserika personer från musik-, konst- och modevärlden, med inriktning på vilka faktorer och personer som varit viktiga och avgörande för Lady Gagas karriär. Analysen är baserad på en teori om Lady Gagas strategier kallad 4E efter ledorden emotions (känslor), erfarenhet, engagemang och exklusivitet. Intervjuerna och fallstudien bekräftar 4E-teorin på alla fyra punkter. Analysen visar att två ytterligare viktiga faktorer är vikten av stödjande grupper runt en ny okänd artist och New Yorks mångfald av artister, musiker och konstnärer.

Graphene Oxide: A Carrier For Pharmaceuticals And A Scaffold For Cell Interactions.

During the last ten years, graphene oxide has been explored in many applications due to its remarkable electroconductivity, thermal properties and mobility of charge carriers, among other properties. As discussed in this review, the literature suggests that a total characterization of graphene oxide must be conducted because oxidation debris (synthesis impurities) present in the graphene oxides could act as a graphene oxide surfactant, stabilizing aqueous dispersions. It is also important to note that the structure models of graphene oxide need to be revisited because of significant implications for its chemical composition and its direct covalent functionalization. Another aspect that is discussed is the need to consider graphene oxide surface chemistry. The hemolysis assay is recommended as a reliable test for the preliminary assessment of graphene oxide toxicity, biocompatibility and cell membrane interaction. More recently, graphene oxide has been extensively explored for drug delivery applications. An important increase in research efforts in this emerging field is clearly represented by the hundreds of related publications per year, including some reviews. Many studies have been performed to explore the graphene oxide properties that enable it to deliver more than one activity simultaneously and to combine multidrug systems with photothermal therapy, indicating that graphene oxide is an attractive tool to overcome hurdles in cancer therapies. Some strategic aspects of the application of these materials in cancer treatment are also discussed. In vitro studies have indicated that graphene oxide can also promote stem cell adhesion, growth and differentiation, and this review discusses the recent and pertinent findings regarding graphene oxide as a valuable nanomaterial for stem cell research in medicine. The protein corona is a key concept in nanomedicine and nanotoxicology because it provides a biomolecular identity for nanomaterials in a biological environment. Understanding protein corona-nanomaterial interactions and their influence on cellular responses is a challenging task at the nanobiointerface. New aspects and developments in this area are discussed.

Pharmacological Characterization Of The Relaxation Induced By The Soluble Guanylate Cyclase Activator, Bay 60-2770 In Rabbit Corpus Cavernosum.

To characterize the relaxation induced by the soluble guanylate cyclase (sGC) activator, BAY 60-2770 in rabbit corpus cavernosum. Penis from male New Zealand rabbits were removed and fours strips of corpus cavernosum (CC) were obtained. Concentration-response curves to BAY 60-2770 were carried out in the absence and presence of inhibitors of nitric oxide synthase, L-NAME (100 μM), sGC, ODQ (10 μM) and phosphodiestarase type 5, tadalafil (0.1 μM). The potency (pEC50) and maximal response (Emax) values were determined. Second, electrical-field stimulation (EFS)-induced contraction or relaxation was realized in the absence and presence of BAY 60-2770 (0.1 or 1 μM) alone or in combination of ODQ (10 μM). In the case of EFS-induced relaxation two protocols were realized: 1) ODQ (10 μM) was first incubated for 20 min and then BAY 60-2770 (1 μM) was added for another 20 min (ODQ + BAY 60-2770). In different CC strips, BAY 60-2770 was incubated for 20 min followed by another 20 min with ODQ (BAY 60-2770 + ODQ). The intracellular levels of cyclic guanosine monophosphate (cGMP) were also determined. BAY 60-2770 potently relaxed rabbit CC with pEC50 and Emax values of 7.58 ± 0.19 and 81 ± 4%, respectively. The inhibitors ODQ (n=7) or tadalafil (n=7) produced 4.2- and 6.3-leftward shifts, respectively in BAY 60-2770-induced relaxation without interfering on the Emax values. The intracellular levels of cGMP were augmented after stimulation with BAY 60-2770 (1 μM) alone, whereas its co-incubation with ODQ produced even higher levels of cGMP. The EFS-induced contraction was reduced in the presence of BAY 60-2770 (1 μM) and this inhibition was even greater when BAY 60-2770 was co-incubated with ODQ. The nitrergic stimulation induced CC relaxation, which was abolished in the presence of ODQ. BAY 60-2770 alone increased the amplitude of relaxation. Co-incubation of ODQ and BAY 60-2770 did not alter the relaxation in comparison with ODQ alone. Interestingly, when BAY 60-2770 was incubated prior to ODQ, EFS-induced relaxation was partly restored in comparison with ODQ alone or ODQ + BAY 60-2770. Considering that the relaxation induced by the sGC activator, BAY 60-2770 was increased after sGC oxidation and unaltered in the absence of nitric oxide, these class of substances are advantageous over sGC stimulators or PDE5 inhibitors for the treatment in those patients with erectile dysfunction and high endothelial damage.

Mechanistic aspects of the isomerization of Z-vinylic tellurides double bonds in the synthesis of potassium Z-vinyltrifluoroborate salts

Through direct transmetalation reaction of Z-vinylic tellurides with nBuLi was observed the unexpected isomerization of double bonds leading to potassium E-vinyltrifluoroborates salts in low to moderate yields. Using EPR spin trapping experiments the radical species that promoted the stereoinversion of Z-vinylic organometallic species during the preparation of potassium vinyltrifluoroborate salts was identified. The experiments support the proposed mechanism, which is based on the homolytic cleavage of the TenBu bond.

Environmental stresses inhibit splicing in the aquatic fungus Blastocladiella emersonii

Background: Exposure of cells to environmental stress conditions can lead to the interruption of several intracellular processes, in particular those performed by macromolecular complexes such as the spliceosome. Results: During nucleotide sequencing of cDNA libraries constructed using RNA isolated from B. emersonii cells submitted to heat shock and cadmium stress, a large number of ESTs with retained introns was observed. Among the 6,350 ESTs obtained through sequencing of stress cDNA libraries, 181 ESTs presented putative introns (2.9%), while sequencing of cDNA libraries from unstressed B. emersonii cells revealed only 0.2% of ESTs containing introns. These data indicate an enrichment of ESTs with introns in B. emersonii stress cDNA libraries. Among the 85 genes corresponding to the ESTs that retained introns, 19 showed more than one intron and three showed three introns, with intron length ranging from 55 to 333 nucleotides. Canonical splicing junctions were observed in most of these introns, junction sequences being very similar to those found in introns from genes previously characterized in B. emersonii, suggesting that inhibition of splicing during stress is apparently a random process. Confirming our observations, analyses of gpx3 and hsp70 mRNAs by Northern blot and S1 protection assays revealed a strong inhibition of intron splicing in cells submitted to cadmium stress. Conclusion: In conclusion, data indicate that environmental stresses, particularly cadmium treatment, inhibit intron processing in B. emersonii, revealing a new adaptive response to cellular exposure to this heavy metal.
