As tecnologias do corpo no debate público. Análise do debate parlamentar da Lei de Identidade de Gênero argentina

Este artículo interroga el modo en que las transformaciones recientes en el campo de la biomedicina tienen eco en regulaciones que procesan demandas de los colectivos de travestis, transexuales y transgéneros en Argentina. Para ello, analiza el debate parlamentario que culminó con la sanción de la Ley de Identidad de Género, de 2012. Dicho debate es abordado prestando especial atención a los sentidos en torno de las tecnologías biomédicas de transformación corporal y su vínculo con representaciones de género, cuerpo, así como de lo que se concibe como público o privado.This paper interrogates how recent tranfsormations in the biomedical field have resonated upon regulations responding to the legal claims of transvesti, transsexual, and transgender collectives in Argentina. The parliamentary debates that lead to the passing of the Gender Identity Act of 2012 are analyzed, looking in particular at the meanings of biomedical technologies of body transformation, representations of gender and the body, as well as conceptions of public and private.Este artigo indaga sobre o modo com o qual as transformações recentes no campo da biomedicina têm eco em regulações que processam demandas dos coletivos de travestis, transexuais e transgênero na Argentina.

New Late Tertiary Fish Fossils from the Sinda Region, Eastern Zaire

An assemblage of about 200 fish remains, recently collected from late Miocene early Pliocene deposits of the Sinda area, is described. Although the collection is small, several taxa not previously reported from these localities are included. Gymnarchus, Hydrocynus and Bagrus are new for the Sinda-Mogari ichthyofauna, whereas the previously doubtful presence of Clariidae is now confirmed by several finds, including one identifiable as Clarias. The discovery of three outer premaxillary teeth of Shungura Sindacharax along with the numerous Sindacharax lepersonnei specimens is surprising. The Shungura form is considered conspecific with Sindacharax lepersonnei. Other represented taxa are Synodontis, Auchenoglanis and Lates rhachirhinchus. Comparison of the ichthofauna from the oldest deposits (Ongoliba Beds) with that of the Middle Member of the Sinda Beds shows a decline in characiforms and an increase in siluriforms through time. Reconstruction of the former aquatic environment indicates a large and deep permanent water-body with shallow and marshy habitats at its margins

Producción generizada de los cuerpos en el discurso jurídico argentino. Análisis de tres fallos correspondientes al período 1970 – 2010

This paper analyzes how bodies in contemporary societies are produced and socially regulated through legal discourses. Three rulings produced by the Argentine Justice Department between 1970 and 2010 are analyzed.  These rulings constitute requests for genital reassignment surgery, change of name and sex in legal registers, petitions made by people whose corporalities defy the dominant gender rules. The analysis aims to trace changes and continuities in the epistemic frames available for reading the other bodies crystallized in legal discourse, as well as to inquire the characteristics of the current ways of thinking. The essay shows that through the analysis of the regulation of bodies and sexualities it is possible to visualize mechanisms through which we define what is considered human, and how ideals of citizenship are historically configured.Este trabajo se propone analizar la producción y regulación social de las corporalidades en las sociedades contemporáneas a través del discurso jurídico. Se analizan tres fallos producidos por el poder judicial argentino entre los años 1970 y 2010 que procesan solicitudes para la realización de cirugías de reasignación genital y cambio de nombre y sexo en el documento de identidad de personas cuyas corporalidades desafían la normatividad de género. El análisis indaga en torno a los cambios y continuidades en los marcos epistémicos disponibles para la lectura de los cuerpos-otros en el discurso jurídico y profundiza en las características de los esquemas actualmente vigentes. Del trabajo se desprende que a través del análisis de la regulación de los cuerpos y las sexualidades es posible visualizar los mecanismos a través de los cuales se define tanto lo humano como los ideales de ciudadanía históricamente configurados

The Holocene occurrence of the European catfish (<i>Silurus glanis</i>) in Belgium: the archaeozoological evidence

An overview is given of the skeletal remains of the European catfish Silurus glanis found thus far in Belgian archaeological sites. These finds demonstrate that the species is autochthonous and allow documenting its occurrence and disappearance during the Holocene in the Scheldt and Meuse basins. Possible causes for the local extinction of this catfish are discussed

Ultrasonic Superharmonic Imaging

Medical ultrasound is one of the most prevalent imaging techniques used for diagnosing patients. The technique allows for the visualization of tissues in the human body. Compared to competing imaging techniques such as CT or MRI, medical ultrasound has numerous advantages: it is real-time, safe (no radiation is involved), inexpensive and portable. Over the years medical ultrasound equipment has become smaller and the image quality has improved considerably. Similar to CT or MRI, contrast agents are also used in medical ultrasound. Their use comprises e.g. endocardial border delineation, the improvement of blood flow detection using Doppler methods in cardiology and radiology, and the visualization of malignant tumors (Emmer, 2009; Vos, 2010). Ultrasound is also commonly used for therapeutic applications such as High Intensity Focused Ultrasound (HIFU), which is used for the noninvasive treatment of tumors by ablation, and extracorporeal shock wave lithotripsy, which is used for the noninvasive treatment of urinary calculosis and biliary calculi. The therapeutic applications for contrast agents are currently under research and range from the stimulated uptake of bioactive materials (van Wamel et al., 2006), to drug delivery (Kooiman et al., 2009) and the treatment of tumors by bloodvessel destruction (Skyba et al., 1998)

Metagenomic analysis of dental calculus in ancient Egyptian baboons

Dental calculus, or mineralized plaque, represents a record of ancient biomolecules and food residues. Recently, ancient metagenomics made it possible to unlock the wealth of microbial and dietary information of dental calculus to reconstruct oral microbiomes and lifestyle of humans from the past. Although most studies have so far focused on ancient humans, dental calculus is known to form in a wide range of animals, potentially informing on how human-animal interactions changed the animals' oral ecology. Here, we characterise the oral microbiome of six ancient Egyptian baboons held in captivity during the late Pharaonic era (9th-6th centuries BC) and of two historical baboons from a zoo via shotgun metagenomics. We demonstrate that these captive baboons possessed a distinctive oral microbiome when compared to ancient and modern humans, Neanderthals and a wild chimpanzee. These results may reflect the omnivorous dietary behaviour of baboons, even though health, food provisioning and other factors associated with human management, may have changed the baboons' oral microbiome. We anticipate our study to be a starting point for more extensive studies on ancient animal oral microbiomes to examine the extent to which domestication and human management in the past affected the diet, health and lifestyle of target animals
