MEDISAN , 2013,
Abstract: Se efectuó un estudio descriptivo y prospectivo de 556 pacientes con hernia inguinal, expuestos a tratamiento quirúrgico ambulatorio en el Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora" de Santiago de Cuba, desde enero de 2010 hasta diciembre de 2012, con vistas a identificar los resultados, mediante técnicas de reparación herniaria (faciales y aponeuróticas) y el uso de bioprótesis. En la serie predominaron los hombres de 60 a os y más con hernia inguinal indirecta, así como la anestesia local infiltrativa. Las técnicas quirúrgicas más empleadas resultaron ser las fasciales, realizadas sin tensión, en forma de herniorrafia o hernioplastia, con mallas de polipropileno y muy pocas recidivas. A descriptive and prospective study was carried out in 556 patients with inguinal hernia, who underwent outpatient surgical treatment in "Saturnino Lora" Provincial Teaching Hospital of Santiago de Cuba, from January 2010 to December 2012, in order to identify the results by means of hernial repair techniques (facial and aponeurotic) and the use of bioprosthesis. Men of 60 years and over with indirect inguinal hernia and infiltrating local anesthesia predominated in the case material. The most used surgical techniques were the fascial ones, without tension, as herniorrhaphy or hernioplasty, with polypropylene mesh and few relapses.

Ramírez-Duarte, Wilson F.;Pineda-Quiroga, Carolina;Martínez, Nhora;Eslava-Mocha, Pedro R.;
Neotropical Ichthyology , 2011, DOI: 10.1590/S1679-62252011005000036
Abstract: the use of sodium chloride (0.5 g/l and 1 g/l) and zeolite (22.7 g/l) during shipment (48 h) of ancistrus triradiatus at high temperatures (between 24.5 and 34oc) were evaluated. several water quality parameters (dissolved oxygen, ph, conductivity, and total ammonia) were measured before and after shipment. glycemia was measured before shipment and at 24 and 48 h after shipment. after shipment, a resistance test was carried out in a high concentration of sodium chloride, and mortality was recorded after shipment, and 7 days post-shipment. while the two evaluated substances increased survival of a. triradiatus challenged by high temperatures during shipment, the best result was obtained with 1 g/l of sodium chloride.

While the two evaluated substances increased survival of A. triradiatus challenged by high temperatures during shipment, the best result was obtained with 1 g/L of sodium chloride. O uso de cloreto de sódio (0,5 g/L e 1 g/L) e zeolita (22,7 g/L) foram avaliados durante o transporte (48 h) de Ancistrus triradiatus em altas temperaturas (entre 24,5 e 34oC). Os seguintes parametros foram monitorados: pH, oxigênio dissolvido, condutividade e am nia antes e depois do transporte. Também foi mensurada a concentra o de glicose no sangue antes do transporte e 0, 24 e 48 h após o transporte. Foi realizado um teste de resistência a altas concentra es de cloreto de sódio após o transporte, sendo registrada a mortalidade no final do transporte e após 7 dias. As duas substancias testadas aumentam a sobrevivência de A. triradiatus a altas temperaturas durante o transporte, porém o melhor resultado foi obtido com o uso de 1 g/L cloreto de sódio.

Memórias do Instituto Oswaldo Cruz , 1998,
Abstract: The kinetoplastid membrane protein 11 (KMP-11) has been recently described in Leishmania (Leishmania) donovani as a major component of the promastigote membrane. Two oligonucleotide primers were synthesized to PCR-amplify the entire coding region of New World Leishmania species. The Leishmania (Viannia) panamensis amplification product was cloned, sequenced and the putative amino acid sequence determined. A remarkably high degree of sequence homology was observed with the corresponding molecule of L. (L) donovani and L. (L) infantum (97% and 96%, respectively). Southern blot analysis showed that the KMP-11 locus is conformed by three copies of the gene. The L. (V) panamensis ORF was subsequently cloned in a high expression vector and the recombinant protein was induced and purified from Escherichia coli cultures. Immunoblot analysis showed that 80%, 77% and 100% sera from cutaneous, mucocutaneous and visceral leishmaniasis patients, respectively, recognized the recombinant KMP-11 protein. In a similar assay, 86% of asymptomatic Leishmania-infected individuals showed IgG antibodies against the rKMP-11. We propose that KMP-11 could be used as a serologic marker for infection and disease caused by Leishmania in America.
Al- ajīra al-saniyya: una fuente relevante para el siglo XII en la Península Ibérica
Ramírez-del-Río, José
Al-Qantara : Revista de Estudios Arabes , 2012,
Abstract: The work al-Dhakhīra al-saniyya fī ta’rīkh al-dawla al-marīniyya records the history of the Marīnid dynasty, including a number of references to other Islamic regions like Egypt, Syria and al-Andalus. The authorship of this chronicle has not yet been solved. The aim of this paper is to provide the most relevant information on the issue. Alongside with other type of information concerning al-Andalus, this paper focuses on that which concerns the territory conquered by the Kingdom of Castile throughout the 13th century, and which so far has been mostly disregarded. It undoubtedly contributes to improve our knowledge of the period, especially as regards both the destiny of the conquered Muslim populations and the chronology of the conquest. We will also focus here on the political leaders of al-Andalus and Maghreb, their reactions towards the Christian conquests, ranging from utter resistance to conversion, and the importance this group attached to fighting the Christians, as a key factor of the political legitimacy of the Banū Marīn to guide the Islamic community, a point that greatly concerns the author of the present chronicle. La obra al- ajīra al-saniyya fī ta’rīj aldawla al-marīniyya, que aborda la historia de los Banū Marīn, incluye una serie de noticias referentes a otras tierras de la Dār al-Islam, como Egipto, Siria o al-Andalus. La autoría de la misma no ha sido determinada, por lo que se alaremos las noticias más destacadas sobre este asunto. De la información que ofrece esta obra acerca de al-Andalus, este artículo se centra en el análisis de los fragmentos relativos a los territorios conquistados por Castilla durante el s. XIII, que no había sido aprovechada hasta el momento, y que contribuye a ampliar nuestro conocimiento acerca de este período histórico, muy especialmente por lo que respecta a la suerte que corrieron las poblaciones musulmanas y a la cronología de la conquista. Abordamos las actitudes adoptadas por los dirigentes políticos de al-Andalus y el Magreb, ante el avance de los cristianos, desde la resistencia hasta la conversión, y la importancia que este grupo concedió a las luchas contra los cristianos, que fueron un elemento de legitimación del poder político de los Banū Marīn, objetivo destacado del autor de la obra.
