Décrire et convaincre: rhétoriques visuelles de la cinématographie en médecine [Describe and convince: visual rhetoric of cinematography in medicine]

The tools of visualisation occupy a central place in medicine. Far from being simple accessories of glance, they literally constitute objects of medicine. Such empirical acknowledgement and epistemological position open a vast field of investigation: visual technologies of medical knowledge. This article studies the development and transformation of medical objects which have permitted to assess the role of temporality in the epistemology of medicine. It firstly examines the general problem of the relationships between cinema, animated image and medicine and secondly, the contribution of the German doctor Martin Weiser to medical cinematography as a method. Finally, a typology is sketched out organising the variety of the visual technology of movement under the perspective of the development of specific visual techniques in medicine.

The tricks of the trade (un)exposed

One of the filmic trends which has been neglected by the Academy Awards is the metacinema, which for practical purposes I will consider to be a cross between the complexities of the self-reflexive cinema (highly connoted with modernism) and the Hollywood Film (the classical films about the urge to ‘make it’ in Hollywood). Indeed, these films have always existed and some, as Sunset Boulevard (Billy Wilder, 1950, USA) and Mulholland Dr. (David Lynch, 2001, FRA/USA), have even made it to the ceremony, but were, predictably, defeated in the main categories, by other more ‘serious’ or less self-reflexive products. The United States has always insisted on not revealing the tricks of the trade while, ironically, generating films that deal with this theme, in order to cater to the curiosity of the metacinema-inclined spectator. For this reason such films are usually about the universe of cinema but not its medium, at least not in a way that discloses the operations of the technical apparatus. Why are these films not viewed as serious enough and artistic enough to be awarded Oscars by the Academy in the categories of Best Picture, Best Director, Best Screenplay, and Best Cinematography? Are they being discarded for the same reasons that comedy and musicals usually are? Or are they being punished for being too unveiling? Or is the industry going for commercial products that can easily be pushed on a global scale and make a profit?

The role of behavior in the survival of Biomphalaria glabrata in biossays with the plant molluscicide Phytolacca dodecandra

This work examines the role of behavior in the survival of Biomphalaria glabrata exposed to 25, 50 75 and 100 mgl-1 of Phytolacca dodecandra. Time-lapse cinematography was used to quantify accurately the following parameters: (a) frequency of exits from the solution, (b) time spent out of the solution and (c) time elapsed until the first exit from the solution. These behavior patterns were statistically compared between surviving snails and those which later died. The proportion of surviving snails leaving the liquid medium was significantly higher than that of dying snails. In addition, the surviving group spent significantly more time out of the solution than the group which died, except for the 100 mgl-1 concentration. However, no significant difference was detected in the time elapsed until the first exit from the solution. It can be concluded that both the tendency to leave the P. dodecandra solutions, and the time spent out of them, contributed significantly to snail survival. Molluscicide bioassays should take into account the possibility that some behavior patterns of planorbids might contribute to the protection of the snails.

Rôle de l'inactivité physique dans l'étiologie de l'obésité [The role of physical inactivity in the etiology of obesity].

The activity-related energy expenditure mainly depends upon body weight, the type, intensity and duration of the exercise as well as the mechanical efficiency with which the subjects perform the work. Controversy still exist about the role of hypoactivity in the aetiology of obesity both in adolescence and adulthood. A number of experimental studies based on indirect assessment of physical activity (such as pedometers, accelerometers, cinematography and heart rate) have demonstrated a significant reduction in spontaneous physical activity in certain obese groups as compared to lean matched controls. On the other hand, direct measurements of energy expenditure (by indirect calorimetry) have shown a linear relationship between body weight and 24-hour (or activity-related) energy expenditure. It therefore appears that despite the greater placidity characterising some grossly obese subjects, the absolute rate of energy expenditure - particularly in weight bearing activities - is not lower than in lean subjects, since the hypoactivity does not fully compensate for the greater gross energy cost of a given activity.

Inhibition of protein kinase B activity induces cell cycle arrest and apoptosis during early G₁ phase in CHO cells.

Inhibition of PKB (protein kinase B) activity using a highly selective PKB inhibitor resulted in inhibition of cell cycle progression only if cells were in early G1 phase at the time of addition of the inhibitor, as demonstrated by time-lapse cinematography. Addition of the inhibitor during mitosis up to 2 h after mitosis resulted in arrest of the cells in early G1 phase, as deduced from the expression of cyclins D and A and incorporation of thymidine. After 24 h of cell cycle arrest, cells expressed the cleaved caspase-3, a central mediator of apoptosis. These results demonstrate that PKB activity in early G1 phase is required to prevent the induction of apoptosis. Using antibodies, it was demonstrated that active PKB translocates to the nucleus during early G1 phase, while an even distribution of PKB was observed through cytoplasm and nucleus during the end of G1 phase.

"En estado crítico" o el negocio de la salud

Supuesta la bondad moral y técnica de la libertad de empresa, o como se la quiera llamar, ¿ésta debe alcanzar también a las cosas relacionadas con la medicina y la sanidad?

"Las invasiones bárbaras" o del buen morir

Sorprende que en estos tiempos de exaltación de la autonomía individual, la última fase de la vida sea librada a la iniciativa ajena y resulte tan radicalmente heterónoma. Quizála razón sea que no concebimos nuestra muerte, ni la de los demás, como un trance vital sino, repito, como el desenlace, como algo que ya no es vida, sino punto final de la vida...

"Yo, robot" o las tribulaciones de un robot kantiano

Las tres leyes de la robótica no son más que los principios esenciales de una gran cantidad de sistemas éticos del mundo... ¿qué aspectos bioéticos nos devela esta película?.

"Blade Runner" o la pregunta por la dignidad humana

Al pensar en la relación entre el fundamento de la dignidad humana y la resolución de algunos problemas bioéticos, me vino a la cabeza Blade Runner, la película de Ridley Scott basada en un relato de Philip K. Dickque lleva el extravagante título de ¿Sueñan los androides con ovejas eléctricas? (extravagante si vemos la película pero no tanto si leemos el relato)...

"Colegas" : el aborto en España, 1982-2007

Desde el estreno de Colegas, el 25 de octubre de 1982, hasta los recientes sucesos de noviembre y diciembre de 2007, han pasado veinticinco años, todo un cuarto de siglode relativa paz en el todavía espinoso asunto del aborto, una paz que parece que puede truncarse a raíz delos sucesos aludidos, que no son otros que las acciones fiscales y judiciales contra algunas clínicas de Barcelona en las que se practica la interrupción voluntaria del embarazo...

"El secreto de Vera Drake" y nuestro secreto: aborto e hipocresía social

La historia de Vera Drake nos recuerda no sólo los tiempos pasados sino también los nuestros, porque, como entonces, las mujeres todavía no controlan su cuerpo; pueden abortar, pero tienen que mentir sobre el por qué; pueden abortar, pero eso no forma parte de su derecho a la salud y a la sanidad básicas. Detrás de ello lo que asomaes una cierta construcción ideológica del aborto que aún mantiene parte de la fuerza que tuvo antaño, y que, por eso, la bioética debe seguir revisando y cuestionando.
