Flexibility of microstructural adaptations in airway smooth muscle.

J Appl Physiol (1985) 2021 May 15;130(5):1555-1561. Epub 2021 Apr 15.

Institut Universitaire de Cardiologie et de Pneumologie de Québec, Université Laval, Quebec, Canada.

The airway smooth muscle undergoes an elastic transition during a sustained contraction, characterized by a gradual decrease in hysteresivity caused by a relatively greater rate of increase in elastance than resistance. We recently demonstrated that these mechanical changes are more likely to persist after a large strain when they are acquired in dynamic versus static conditions; as if the microstructural adaptations liable for the elastic transition are more flexible when they evolve in dynamic conditions. The extent of this flexibility is undefined. Read More

Wing morphometrics of Aedes (Ochlerotatus) albifasciatus (Macquart, 1838) (Diptera: Culicidae) from different climatic regions of Argentina.

Parasit Vectors 2018 05 16;11(1):303. Epub 2018 May 16.

Departamento de Ecología, Genética y Evolución, Grupo de Estudio de Mosquitos, Universidad de Buenos Aires, Facultad de Ciencias Exactas y Naturales, Buenos Aires, Argentina.

Background: Gene flow restrictions between populations of Aedes albifasciatus, the vector of Western equine encephalitis and Dirophilaria immitis, have been described in the central region of Argentina. Genetic and eco-physiological variations usually result in local forms reflecting the climatic regions. Mosquito wings and their different parts have ecological functions in flight and communication.

GaMYB85, an R2R3 MYB gene, in transgenic Arabidopsis plays an important role in drought tolerance.

BMC Plant Biol 2017 08 22;17(1):142. Epub 2017 Aug 22.

State Key Laboratory of Cotton Biology, Institute of Cotton Research of Chinese Academy of Agricultural Science (ICR, CAAS), Anyang, 455000, China.

Background: MYB transcription factors (TFs) are one of the largest families of TFs in higher plants and are involved in diverse biological, functional, and structural processes. Previously, very few functional validation studies on R2R3 MYB have been conducted in cotton in response to abiotic stresses. In the current study, GaMYB85, a cotton R2R3 MYB TF, was ectopically expressed in Arabidopsis thaliana (Col-0) and was functionally characterized by overexpression in transgenic plants. Read More

Temperature influences whole-animal rates of metabolism but not protein synthesis in a temperate intertidal isopod.

Physiol Biochem Zool 2005 Mar-Apr;78(2):227-38. Epub 2005 Mar 3.

School of Biological Sciences, University of Wales, Bangor, Gwynedd, UK.

The effects of temperature on two important biological rate processes, whole-body rates of oxygen uptake (M dot o2) and protein synthesis (k(s)), were investigated in the temperate intertidal isopod Ligia oceanica at two different times of the year. Animals were collected in January (winter) and June (summer) and either subjected to an acute temperature change after 24 h (acclimatized) or acclimated to various temperatures for 4 wk. In both cases, M dot o2 increased with temperature, with a Q(10) of 2. Read More

Water metabolism in the eel acclimated to sea water: from mouth to intestine.

Comp Biochem Physiol B Biochem Mol Biol 2003 Dec;136(4):621-33

Laboratory of Integrative Physiology, Faculty of Integrated Arts and Sciences, Hiroshima University, Kagamiyama 1-7-1, Higashi-Hiroshima 739-8521, Japan.

Eels seem to be a suitable model system for analysing regulatory mechanisms of drinking behavior in vertebrates, since most dipsogens and antidipsogens in mammals influence the drinking rate in the seawater eels similarly. The drinking behavior in fishes consists of swallowing alone, since they live in water and water is constantly held in the mouth for respiration. Therefore, contraction of the upper esophageal sphincter (UES) muscle limits the drinking rate in fishes. Read More

Behav Processes 1995 Dec;35(1-3):5-18

In the natural setting, cognitive processes direct behavioural adjustments and sometimes result in behavioural novelties which allow the organism to cope with environmental pressures. The resulting behavioural changes exhibit various forms which are dependent upon different causal factors and cognitive processes. Under long-lasting environmental changes, these behavioural adaptations can become hereditary either through the process of cultural transmission or through genetic mechanisms sensitive to selective forces acting on genotypes.

Detection of high-risk subjects for high altitude diseases.

Int J Sports Med 1992 Oct;13 Suppl 1:S76-8

Association pour la Recherche en Physiologie de l'Environnement, UFR Médecine, Bobigny, France.

The variability in sensitivity to acute mountain sickness among individuals is a phenomenon well known to physicians and high altitude alpinists. The measurement of cardiac and respiratory responses to hypoxia (FIO2 = 0.115) at rest and during exercise (50% VO2max) allows the detection of those subjects who are more liable to suffer from high altitude diseases.

Characteristics of male fallow deer muscle at a time of sex-related muscle growth.

Growth 1985 ;49(2):190-201

Muscle characteristics of male fallow deer undergoing neck muscle enlargement as the mating season (rut) approached were studied. Five commercially-raised males were slaughtered prerut and five were slaughtered 11 weeks later, just before the rut began. During this period, increases in individual muscle weight were not the same: two of the three neck muscles studied grew more rapidly than the average, whereas the back and two hind leg muscles grew more slowly.
