In 2004 and 2007, the American Physiological Society (APS) Trainee Advisory Committee (TAC) conducted surveys of graduate students, postdoctoral fellows, and new investigators in physiology to identify topics and issues important to those trainees. Two major trends emerged from the data. First, trainees in 2007 expressed somewhat greater interest in professional development information than did...
A rich phenomenology could be studied in the misfocused vision through a pinhole or a system of pinholes punched on a black cardboard. Some of the observations we describe here can be also found in the ancient Literature. In this paper, we aim to rediscover and discuss some particular effects in light of a new perspective which provide an answer to interesting zero-cost experiments. In particul...
Microorganisms are vital in mediating the earth's biogeochemical cycles; yet, despite our rapidly increasing ability to explore complex environmental microbial communities, the relationship between microbial community structure and ecosystem processes remains poorly understood. Here, we address a fundamental and unanswered question in microbial ecology: 'When do we need to understand microbial ...
Physical exercise represents a physiological stress to the organism producing acute integrative physiological adjustments, whereas repetitive and regular sessions of physical effort provoke chronic physiological adaptations that develop throughout the weeks of training and increase exercise capacity. The present work presents and discusses the concept of subacute effects of exercise, those phys...
Realistically, most professional and general physiology courses will have only one or two lecture hours devoted to cardiovascular reflexes. Therefore, it is important to choose carefully the points you consider the most important and focus your lecture(s) to stress these points. In writing this article, I have tried to highlight the concepts that, in my opinion, are the most important. I have g...
Conservation physiology was first identified as an emerging discipline in a landmark paper by Wikelski and Cooke (2006). They defined it as ‘the study of physiological responses of organisms to human alteration of the environment that might cause or contribute to population decline’. Although the case studies and examples presented by Wikelski and Cooke (2006) focused on wild animals, they also...
Measurements of photosynthetic processes in hydrophytes mostly involve photosynthometers, which capture the escaping gas for subsequent analysis The most common method to detect changes in the rate of photosynthetic processes is to count the series of escaping gas bubbles. The emerging bubbles are either simply counted or they are recorded using light barriers, which is very difficult because o...
Recent evidence has demonstrated that inquiry-based physiology laboratories improve students' critical- and analytical-thinking skills. We implemented inquiry-based learning into three physiology courses: Comparative Vertebrate Physiology (majors), Human Physiology (majors), and Human Anatomy and Physiology (nonmajors). The aims of our curricular modifications were to improve the teaching of ph...
