Aumento de la fertilidad mediante técnicas de procesamiento avanzado de semen: caso clínico

Current equine reproductive clinic aims to improve subfertile stallions semen quality, (which is furthermore affected by the processing protocol) and maintain this quality during storage. The aim of this paper is to present a case referred to the Hospital Clínico Veterinario Complutense, of a stallion with low sperm quality, and 0% fertility rate in the first batch of mares served. Due to these results it was decided to perform a special semen processing protocol, developed by our laboratory, in order to increase its quality throughout a colloidal centrifugation technique with EquiPure® This system is able to increase semen quality and maintain itduring cooling preservation, obtaining results of around 57,1% of total fertility, which validates this technique as an effective method for subfertile stallions semen processing.La clínica reproductiva equina actual persigue mejorar la calidad seminal de sementales subfértiles, (la cual, además, se ve afectada por el procesamiento del semen) y que ésta se conserve durante el almacenamiento. El objetivo de este trabajo es presentar un caso clínico remitido al Hospital Clínico Veterinario Complutense, sobre un semental que presenta una baja calidad seminal, siendo la fertilidad del primer lote de yeguas del 0%. Ante estos resultados se decide realizar un procesado del semen, desarrollado por nuestro laboratorio, enfocado a aumentar su calidad mediante un protocolo de centrifugación coloidal con EquiPure® (Nidacon International AB). La aplicación de este protocolo consigue aumentar la calidad seminal y mantenerla durante la conservación en refrigeración, obteniéndose unos resultados de fertilidad total del 57,1%, lo que lo valida como método efectivo para el procesado del semen en casos de sementales subfértiles

HIV, Globalization and Topology: Of Prepositions and Propositions

In this paper we explore how two enactments of HIV – the UN’s AIDS Clock and clinical trials for an HIV biomedical prevention technology or pre-exposure prophylaxis (PrEP) - entail particular globalizing and localizing dynamics. Drawing on Latour’s and Whitehead’s concept of proposition, and Serres’ call for a philosophy of prepositions, we use the composite notion of pre/propostitons to trace the shifting topological status of HIV. For example, we show how PrEP emerges through topological entwinements of globalizing biomedical standardization, localizing protests against PrEP trials and globalizing ethical principles. We go on to examine how our own analysis manifests a parallel topological pattern in which we deploy a globalizing argument about the localizing of the globalizing found in the AIDS clock and the PrEP trails. Finally, we consider how the movement of ‘topology’ into the social sciences might itself benefit from a topological treatment

Retreating to nature : rethinking 'therapeutic landscapes'

There is a long history of removing oneself from ‘society’ in order to recuperate or repair. This paper considers a yoga and massage retreat in Southern Spain, and what opportunities this retreat experience might offer for recuperation and the creation of healthy bodies. The paper positions ‘nature’ as an active participant, and as ‘enrolled’ in the experiences of the retreat as a ‘therapeutic landscape’, and questions how and what particular aspects of yoga practice (in intimate relation with place) give rise to therapeutic experiences

Negotiating the inhuman: Bakhtin, materiality and the instrumentalization of climate change

The article argues that the work of literary theorist Mikhail M. Bakhtin presents a starting point for thinking about the instrumentalization of climate change. Bakhtin’s conceptualization of human–world relationships, encapsulated in the concept of ‘cosmic terror’, places a strong focus on our perception of the ‘inhuman’. Suggesting a link between the perceived alienness and instability of the world and in the exploitation of the resulting fear of change by political and religious forces, Bakhtin asserts that the latter can only be resisted if our desire for a false stability in the world is overcome. The key to this overcoming of fear, for him, lies in recognizing and confronting the worldly relations of the human body. This consciousness represents the beginning of one’s ‘deautomatization’ from following established patterns of reactions to predicted or real changes. In the vein of several theorists and artists of his time who explored similar ‘deautomatization’ strategies – examples include Shklovsky’s ‘ostranenie’, Brecht’s ‘Verfremdung’, Artaud’s emotional ‘cruelty’ and Bataille’s ‘base materialism’ – Bakhtin proposes a more playful and widely accessible experimentation to deconstruct our ‘habitual picture of the world’. Experimentation is envisioned to take place across the material and the textual to increase possibilities for action. Through engaging with Bakhtin’s ideas, this article seeks to draw attention to relations between the imagination of the world and political agency, and the need to include these relations in our own experiments with creating climate change awareness

Alpha-1 antitrypsin deficiency in Italy: regional differences of the PIS and PIZ deficiency alleles

Background. Critical to the effective diagnosis and management of disease is information on its prevalence in a particular geographic area such as Italy. Alpha-1- antitrypsin deficiency (AAT Deficiency) is one of the most common serious hereditary diseases in the world, but its prevalence varies markedly from one country to another. AAT Deficiency affects at least 120.5 million carriers and deficient subjects worldwide for the two most prevalent deficiency alleles PIS and PIZ. This genetic disease is known to exist in Italy and is related to a high risk for development of jaundice in infants, liver disease in children and adults, and pulmonary emphysema in adults. Methods. Studies on the genetic epidemiology of AAT Deficiency has resulted in the development of a unique database that permits a unique analysis of the geographic distribution in 14 different regions located at random from Piemonte to Sicilia. Results. The use of Hardy-Weinberg statistical analysis to evaluate the distribution of these two deficiency alleles has demonstrated striking differences in the frequencies of these two deficiency alleles in these 14 different regions with 23/84 pair wise combinations significantly different (P=0.05) for PIS, and 5/84 combinations for PIZ. Conclusions. These findings demonstrate differences that impact the standards of care and diagnosis of AAT Deficiency in Italy since the prevalence of these deficiency alleles is not uniform throughout the country
