Manual engagement and automation in amateur photography

© 2017, © The Author(s) 2017. Automation has been central to the development of modern photography and, in the age of digital and smartphone photography, now largely defines everyday experience of the photographic process. In this article, we question the acceptance of automation as the default position for photography, arguing that discussions of automation need to move beyond binary concerns of whether to automate or not and, instead, to consider what is being automated and the degree of automation couched within the particularities of people’s practices. We base this upon findings from ethnographic fieldwork with people engaging manually with film-based photography. While automation liberates people from having to interact with various processes of photography, participants in our study reported a greater sense of control, richer experiences and opportunities for experimentation when they were able to engage manually with photographic processes

Continuous ambulatory peritoneal dialysis: pharmacokinetics and clinical outcome of paclitaxel and carboplatin treatment

Purpose: Administration of chemotherapy in patients with renal failure, treated with hemodialysis or continuous ambulatory peritoneal dialysis (CAPD) is still a challenge and literature data is scarce. Here we present a case study of a patient on CAPD, treated with weekly and three-weekly paclitaxel/ carboplatin for recurrent ovarian cancer. Experimental: During the first, second and ninth cycle of treatment, blood, urine and CAPD samples were collected for pharmacokinetic analysis of paclitaxel and total and unbound carboplatin-derived platinum. Results: Treatment was well tolerated by the patient. No excessive toxicity was observed and at the e

Consensus guidelines for the use and interpretation of angiogenesis assays

The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference

Participação do cerebelo no processamento auditivo Participation of the cerebellum in auditory processing

O cerebelo era tradicionalmente visto como um órgão coordenador da motricidade, entretanto é atualmente considerado como um importante centro de integração de sensibilidades e coordenação de várias fases do processo cognitivo. OBJETIVO: é sistematizar as informações da literatura quanto à participação do cerebelo na percepção auditiva. MÉTODOS: foram selecionados na literatura trabalhos em animais sobre a fisiologia e anatomia das vias auditivas do cerebelo, além de trabalhos em humanos sobre diversas funções do cerebelo na percepção auditiva. Foram discutidos os achados da literatura, que há evidências que o cerebelo participa das seguintes funções cognitivas relacionadas à audição: geração verbal; processamento auditivo; atenção auditiva; memória auditiva; raciocínio abstrato; timing; solução de problemas; discriminação sensorial; informação sensorial; processamento da linguagem; operações lingüísticas. CONCLUSÃO: Foi constatado que são incompletas as informações sobre as estruturas, funções e vias auditivas do cerebelo.<br>The cerebellum, traditionally conceived as a controlling organ of motricity, it is today considered an all-important integration center for both sensitivity and coordination of the various phases of the cognitive process. AIM: This paper aims at gather and sort literature information on the cerebellum’s role in the auditory perception. METHODS: We have selected animal studies of both the physiology and the anatomy of the cerebellum auditory pathway, as well as papers on humans discussing several functions of the cerebellum in auditory perception. As for the literature, it has been discussed and concluded that there is evidence that the cerebellum participates in many cognitive functions related to hearing: speech generation, auditory processing, auditory memory, abstract reasoning, timing, solution of problems, sensorial discrimination, sensorial information, language processing, and linguistic operations. CONCLUSION: It has been reported that all information about cerebellum structure, functions and auditory pathways is incomplete
