A reprodução em peixes é controlada pelo eixo hipotálamo-hipófise-gônadas e os fatores que alteram o funcionamento adequado deste eixo são chamados de disruptores endócrinos. Muitos metais têm o papel de disruptores endócrinos e dentre eles destaca-se o alumínio que, além de afetar o sistema endócrino de algumas espécies de peixes, pode alterar a deposição e/ou mobilização de substratos energéticos nestes animais. Sabe-se que o pH pode modular em muitos casos as respostas fisiológicas decorrentes da exposição de peixes a alguns metais, como é o caso do alumínio. Desta forma, o presente trabalho objetiva avaliar as possíveis alterações na fisiologia reprodutiva de duas espécies de peixes teleósteos continentais quando os mesmos são expostos às altas concentrações de alumínio e em pH ácido. Para avaliar estes efeitos foram conduzidos 2 tipos de experimentos: um crônico, realizado com fêmeas de uma espécie de desova total (sincrônica em grupo), Astyanax fasciatus (lambari), durante a sua fase reprodutiva, pelo período de 14 dias; e outro agudo, pelo período de 96 horas, com fêmeas de Oreochromis niloticus (tilápia), espécie de desova parcelada (assincrônica) também em fase reprodutiva. Foram determinadas as concentrações plasmáticas de hormônios esteróides como o cortisol...

Os frutos são classificados em climatéricos e não climatéricos de acordo com o padrão da atividade respiratória e produção de etileno. No entanto, estudos apontam que alguns frutos não se enquadram nessa classificação e, a goiaba, tem sido considerada um deles. Uma vez que há divergências quanto à classificação de alguns frutos em climatéricos e não climatéricos, esse trabalho apresenta hipóteses de estudo para goiaba, pois dados sobre sua fisiologia pós-colheita ainda são contraditórios e para maracujá-amarelo, pois são poucos os dados sobre a sua fisiologia pós-colheita. Este trabalho teve como objetivo caracterizar a fisiologia do amadurecimento de maracujá-amarelo e goiaba 'Pedro Sato' ligados ou não às plantas, bem como, avaliar as respostas desses frutos à aplicação de reguladores do amadurecimento como o etileno e 1-metilciclopropeno (1-MCP). O trabalho foi conduzido em duas etapas. Na etapa 1, foi estimada a concentração endógena de CO2 e etileno de maracujás e goiabas ligados às plantas e em frutos colhidos em diferentes estádios de maturação. Foi fixado um tudo de silicone no epicarpo dos frutos ligados às plantas e coletadas amostras para CO2 e etileno desde o início do desenvolvimento até o completo amadurecimento dos mesmos e em frutos colhidos nos respectivos estádios de maturação para cada espécie frutífera...

A detailed study of the physiology and nutrition of Lampropedia hyalina revealed that it is an aerobic, cytochrome-containing chemoheterotroph which is limited in its energy sources to a few intermediates (and close derivatives) of the Krebs cycle. Reducing compounds at low levels are potent growth inhibitors. The microbe has no photosynthetic ability (despite its previous taxonomic position with the sulfur purple bacteria). The results of a general investigation of its physiology are reported. Added biotin and thiamine are needed for growth in defined media; pantothenate is strongly stimulatory. Alanine, arginine, and tyrosine, as well as NH4Cl, serve as sole nitrogen sources. A unique motion exhibited by cells of a rapidly growing culture is described. Aspects of its metabolism of poly-β-hydroxybutyrate and limiting aspects of its physiology as related to its ecology are discussed.

Major evolutionary trends in animal physiology have been heavily influenced by atmospheric O2 levels. Amongst other important factors, the increase in atmospheric O2 which occurred in the Pre-Cambrian and the development of aerobic respiration beckoned the evolution of animal organ systems that were dedicated to the absorption and transportation of O2, e.g., the respiratory and cardiovascular systems of vertebrates. Global variations of O2 levels in post-Cambrian periods have also been correlated with evolutionary changes in animal physiology, especially cardiorespiratory function. Oxygen transportation systems are, in our view, ultimately controlled by the brain related mechanisms, which senses changes in O2 availability and regulates autonomic and respiratory responses that ensure the survival of the organism in the face of hypoxic challenges. In vertebrates, the major sensorial system for oxygen sensing and responding to hypoxia is the peripheral chemoreflex neuronal pathways, which includes the oxygen chemosensitive glomus cells and several brainstem regions involved in the autonomic regulation of the cardiovascular system and respiratory control. In this review we discuss the concept that regulating O2 homeostasis was one of the primordial roles of the nervous system. We also review the physiology of the peripheral chemoreflex...

A key challenge for the physiology modeling community is to enable the searching, objective comparison and, ultimately, re-use of models and associated data that are interoperable in terms of their physiological meaning. In this work, we outline the development of a workflow to modularize the simulation of tissue-level processes in physiology. In particular, we show how, via this approach, we can systematically extract, parcellate and annotate tissue histology data to represent component units of tissue function. These functional units are semantically interoperable, in terms of their physiological meaning. In particular, they are interoperable with respect to [i] each other and with respect to [ii] a circuitboard representation of long-range advective routes of fluid flow over which to model long-range molecular exchange between these units. We exemplify this approach through the combination of models for physiology-based pharmacokinetics and pharmacodynamics to quantitatively depict biological mechanisms across multiple scales. Links to the data, models and software components that constitute this workflow are found at http://open-physiology.org/.

Rangel EM, Mendes IA, Carnio EC, Marchi Alves LM, Godoy S, Crispim JA. Development, implementation, and assessment of a distance module in endocrine physiology. Adv Physiol Educ 34: 70-74, 2010; doi: 10.1152/advan.00070.2009.-This study aimed to develop, implement, and assess a distance module in endocrine physiology in TelEduc for undergraduate nursing students from a public university in Brazil, with a sample size of 44 students. Stage 1 consisted of the development of the module, through the process of creating a distance course by means of the Web. Stage 2 was the planning of the module's practical functioning, and stage 3 was the planning of student evaluations. In the experts' assessment, the module complied with pedagogical and technical requirements most of the time. In the practical functioning stage, 10 h were dedicated for on-site activities and 10 h for distance activities. Most students (93.2%) were women between 19 and 23 yr of age (75%). The internet was the most used means to remain updated for 23 students (59.0%), and 30 students (68.2%) accessed it from the teaching institution. A personal computer was used by 23 students (56.1%), and most of them (58.1%) learned to use it alone. Access to a forum was more dispersed (variation coefficient: 86.80%) than access to chat (variation coefficient: 65.14%). Average participation was 30 students in forums and 22 students in the chat. Students' final grades in the module averaged 8.5 (SD: 1.2). TelEduc was shown to be efficient in supporting the teaching- learning process of endocrine physiology.

Insulin-like peptides (ILPs) play highly conserved roles in development and physiology. Most animal genomes encode multiple ILPs. Here we identify mechanisms for how the forty Caenorhabditis elegans ILPs coordinate diverse processes, including development, reproduction, longevity and several specific stress responses. Our systematic studies identify an ILP-based combinatorial code for these phenotypes characterized by substantial functional specificity and diversity rather than global redundancy. Notably, we show that ILPs regulate each other transcriptionally, uncovering an ILP-to-ILP regulatory network that underlies the combinatorial phenotypic coding by the ILP family. Extensive analyses of genetic interactions among ILPs reveal how their signals are integrated. A combined analysis of these functional and regulatory ILP interactions identifies local genetic circuits that act in parallel and interact by crosstalk, feedback and compensation. This organization provides emergent mechanisms for phenotypic specificity and graded regulation for the combinatorial phenotypic coding we observe. Our findings also provide insights into how large hormonal networks regulate diverse traits.

Mathematical models and simulations are important tools in discovering key causal relationships governing physiological processes. Simulations guide and improve outcomes of medical interventions involving complex physiology. We developed HumMod, a Windows-based model of integrative human physiology. HumMod consists of 5000 variables describing cardiovascular, respiratory, renal, neural, endocrine, skeletal muscle, and metabolic physiology. The model is constructed from empirical data obtained from peer-reviewed physiological literature. All model details, including variables, parameters, and quantitative relationships, are described in Extensible Markup Language (XML) files. The executable (HumMod.exe) parses the XML and displays the results of the physiological simulations. The XML description of physiology in HumMod's modeling environment allows investigators to add detailed descriptions of human physiology to test new concepts. Additional or revised XML content is parsed and incorporated into the model. The model accurately predicts both qualitative and quantitative changes in clinical and experimental responses. The model is useful in understanding proposed physiological mechanisms and physiological interactions that are not evident...

The effects of NaCl salinity on seed germination, growth, physiology, and biochemistry of two bambara groundnut landraces (Vigna subterranea (L.) Verdc), Kakamega (white seed coat) and Mumias (red seed coat), were investigated with the aim of establishing traits, which can provide a basis for breeding to salt tolerance in groundnuts. A study was conducted under laboratorial and greenhouse conditions. Bambara groundnut seeds and plants were subjected to five concentrations of NaCl solutions with several electrical conductivities: 0 (control), 6.96, 12.93, 19.89, and 25.86 dS m-1. Germination percentage, growth, chlorophyll fluorescence, and leaf chlorophyll content were determined. Sodium chloride salinity (p<0.05) significantly decreased germination and plant growth in both landraces. Mumias had significantly higher total chlorophyll, chlorophyll a and b content compared to Kakamega landrace. Salinity significantly decreased Fv/Fm ratio and electron transport rate in the two landraces, however there were no significant (p>0.05) differences in the Fv/Fm values for Mumias' landrace, as compared to the Control. Overall, Mumias' landrace seeds seemed to be more salt-tolerant at higher salinity levels compared to Kakamega. A greater reduction in growth in Mumias than in Kakamega is a possible indicator for salt tolerance. The chlorophyll fluorescence parameters may not be used to identify salt sensitivity between the two landraces. The results indicated that leaf area and seed germination were suitable parameters for screening the two bambara landraces for salt tolerance.

Warner, Mark E.; During the past three decades the frequency and duration of harmful algal blooms (HABs) have significantly increased causing major economical losses world wide as well as being identified as the cause of a number of human health illnesses. These impacts have brought harmful algal species to the forefront of research efforts which are focused primarily on the effects of abiotic and biotic factors on algal growth. Less effort has been placed on understanding how changes in environmental parameters may impact harmful algal physiology. The effects of elevated CO2 and temperature were studied using the raphidophytes Chattonella subsalsa and Heterosigma akashiwo isolated from the Delaware Inland Bays (DIB), and a cold water isolate of H. akashiwo from Puget Sound, WA. Neither increases in temperature, CO2, or a combined treatment of elevated temperature and CO2, had any significant effect on the growth rates of all three isolates. However, significant changes in physiology and carbon uptake were seen among temperature/CO2 treatments and between strains. Both isolates of H. akashiwo exhibited changes in light harvesting capabilities in response to temperature, with a decrease in maximum carbon assimilation occurring in the cold water isolate. In contrast both elevated temperature and CO2 altered the physiology of C. subsalsa although changes were not additive. Carbon assimilation increased in response to elevated CO2 while temperature had a greater effect on light harvesting in this species. While growth and cell size did not change across any treatments in these raphidophytes...

This paper reviews diverse ways in which the emerging discipline of conservation physiology may contribute to the conservation of anuran amphibians. We first present a summary of the goals of conservation physiology. Then, we review five specific sources of environmental change that are known to affect anurans: introduced pathogens (highlighting the case of chytridiomycosis) and exotic species, pollutants, habitat fragmentation, and global climate change. We discuss these types of environmental change in the context of how and why altered environments may become stressing to anurans and cause population declines. We also discuss synergism among variables that may worsen the effect of environmental alterations, and emphasize the importance of conservation physiology for Brazilian anurans.

This paper is a research and journalistic work that summarizes and synthesizes the scientific development of the physiology of plants in the American tropics, also known as the Neotropics. It contains the contributions of numerous biologists interested in the physiology of tropical plants. The fabulous structural and functional diversity of tropical forests is still the major driver of research in this field. Classical physiological work involving tropical plants, such as the discovery of C4 photosynthesis in sugarcane, is invoked to exemplify the historical and current importance of physiological research in the tropics, and its applications in agriculture, forestry and conservation. An historical background describing the early and more recent development of a tradition on the physiological study of tropical plants is followed by a summary of the research conducted on the physiology of tropical crops. Common areas of interest and influence between the fields of crop physiology and plant ecophysiology are identified and exemplified with problems on the environmental physiology of crops like coffee and cassava. The physiology of tropical forest plants is discussed in terms of its contributions to general plant physiological knowledge in areas such as photosynthetic metabolism and plant water relations. Despite the impressive technical advances achieved during the past decade...

The only extant version of the first lecture course given by Claude Bernard on Experimental Physiology during the winter period of 1847-48 in Collège de France, substituting Magendie, is presented herein. The prominent Paris-graduated physician from Uruguay, Teodoro M. Vilardebó, attended the 46 lectures, wrote them down and transcribed them into a manuscript that he brought back to and kept in Montevideo in 1853. Mañé-Garzón uncovered it in 1987. These Bernard’s lectures review practically all physiology at the beginning of his career, while in later courses, he covered selected themes of experimental physiology and medicine and general scientific subjects at greater depth. Comparison of Bernard’s initial course with his later ones illustrates general physiology’s progress in the more than 35 years of his successful scientific life. The manuscript sheds new light into Bernard’s scientific activity and personality.
