Occurrence and etiology of brown apical necrosis on Persian (English) walnut fruit
No full textIn 1998, a severe fruit drop was observed in Italy, principally on cv. Lara Persian (English) walnut (Juglans regia). Dropped fruit showed a brown patch at the blossom end and blackening and rot of inner tissues. The disease, called brown apical necrosis (BAN), was investigated on fruit collected in Italy and France in 1999. In 2000, studies were carried out in three walnut orchards located in Italy and in France to substantiate the etiology of BAN. Isolations performed from inner diseased fruit tissues yielded several fungi, in decreasing frequency of isolation: species of Fusarium and Alternaria, and one species each of Cladosporium, Colletotrichum, and Phomopsis. However, only Fusarium spp. were recovered from stigmas of BAN-affected fruit. The fungi associated with BAN-diseased fruit and species composition differed among locations and over time, confirming results obtained in previous investigations. The species of Fusarium used in pathogenicity tests reproduced BAN-disease symptoms when inoculated on fruit, whereas an Alternaria alternata isolate caused only limited necrosis of the style. However, the role of the other fungi commonly isolated from BAN-diseased fruit remains to be defined. The walnut blight pathogen, Xanthomonas arboricola pv. juglandis, occasionally was isolated from BAN-diseased fruit. No correlation was found between the extent of external brown patches and the size of inner lesions. Repeated isolations from and inoculations of fruit demonstrated that BAN can be considered a complex disease, and the inner infections originate from the style of the fruit

Do the Jetsons dream of wild sheep? A killjoy reading of the economic singularity by Javier Milei
No full textFil: Zalazar, Belisario. Universidad Nacional de Córdoba. Facultad de Filosofía y Humanidades. Escuela de Letras; Argentina.Fil: Zalazar, Belisario. Consejo Nacional de Investigaciones Científicas y Técnicas; Instituto de Humanidades; Argentina.En el siguiente trabajo, emprenderemos una lectura crítica, aguafiestas y pesimista ‒diría el autor en cuestión‒ del artículo “De los Picapiedras a los Supersónicos: Maravillas del Progreso Tecnológico con Convergencia” (2014), firmado por Javier Milei, por entonces Economista Jefe de la Fundación Acordar. Para ello, reconstruiremos la narrativa de futuro que propone Milei, centrándonos en sus presupuestos teóricos (la singularidad económica principalmente), las operaciones epistemológicas que establecen el régimen de verdad de sus argumentos (lo que llamamos aquí providencialismo estadístico) y el optimismo tecnoeconómico que configura su visión de la historia pasada, presente y por venir.Abstract:
In the following paper, we will undertake a critical, spoilsport, and pessimistic reading, as the author in question would say, of the article "From the Flintstones to the Jetsons: Wonders of Technological Progress with Convergence" (2014) by Javier Milei, then Chief Economist of Fundación Acordar. To do so, we will reconstruct the narrative of the future proposed by Milei, focusing on his theoretical assumptions (mainly the economic Singularity), the epistemological operations that establish the regime of truth of his arguments (what we call here Statistical Providentialism), and the techno-economic optimism that shapes his vision of history past, present, and to come.info:eu-repo/semantics/publishedVersionFil: Zalazar, Belisario.

Belisario Porras Barahona letter to Warren G. Harding, November 26, 1920
No full textIn this letter dated November 20, 1920, President of Panama Belisario Porras Barahona writes to President-elect Warren G. Harding to outline what a working relationship between Panama and the U.S. should look like under his presidency. One major grievance Barahona points out is the United States' interpretation of the Canal Treaty, which should be remedied to be fair to the U.S. and Panama alike. As Panama would like to be the United States' ally, Barahona urges the Panama Canal Treaty to cease to be a cause of oppression, but rather a source of mutual benefit.
This letter is part of the Warren G. Harding Papers (MSS 345). This collection includes correspondence, business records, and other materials documenting Harding’s business career as owner and editor-in-chief of The Daily Marion Star, as well as the various stages of his political career. A significant portion of the collection, and what’s available on Ohio Memory, highlights his 1920 presidential campaign, spanning just before publicly announcing his candidacy to handily defeating Ohio Governor James M. Cox in the election. Correspondents include both Ohio and national businessmen, political figures, and ordinary citizens writing with questions, support, congratulatory notes, and campaign advice. Some of the most interesting insights into the tumultuous political climate in the U.S., the extreme factionalism within the Republican Party in Ohio, and Harding’s campaign strategies are described in letters between Harding and his campaign manager, Harry M. Daugherty. Some of the topics addressed include women’s suffrage, Prohibition, the League of Nations, African American representation and issues, and lingering peace negotiations following World War I
Pro-apoptotic and cytostatic activity of naturally occurring cardenolides
No full textCardenoliddes are steroid glycosides which are known to exert cardiotonic effects by inhibiting the Na+/K+-ATPase. Several of these compds. have been shown also to possess anti-tumor potential. The aim of the present work was the characterization of the tumor cell growth inhibition activity of four cardenolides, isolated from Periploca graeca L., and the mechanisms underlying such an effect. The pro-apoptotic and cytostatic effect of the compds. was tested in U937 (monocytic leukemia) and PC3 (prostate adenocarcinoma). Characterization of apoptosis and cell cycle impairment was obtained by cytofluorimetry and WB. Periplocymarin and periplocin were the most active compds., periplocymarin being more effective than the ref. compd. ouabain. The redn. of cell no. by these two cardenolides was due in PC3 cells mainly to the activation of caspase-dependent apoptotic pathways, while in U937 cells to the induction of cell cycle impairment without extensive cell death. Interestingly, periplocymarin, at cytostatic but non-cytotoxic doses, was shown to sensitize U937 cells to TRAIL. Taken together, our data outline that cardiac glycosides are promising anticancer drugs and contribute to the identification of new natural cardiac glycosides to obtain chem. modified non-cardioactive/low toxic derivs. with enhanced anticancer potency
