Abstract
The modem representations of wakefulness-sleep cycle evolution and the data about dynamics of reactivity of activating and inhibition neurotransmitter systems of the forebrain, converging in striatum, in cold- and warm-blooded vertebrates are considered. The data about dynamics of immune reactivity o...

Abstract
Data on interactions between the paradoxical sleep (PS) and thermoregulation under thermo-comfortable and extreme conditions (in high and low temperatures, forced and spontaneous fasting, acclimation to cold and acclimation to natural winter conditions) are reviewed. The hypothesis of the PS role in...

Abstract
We speculate that TICAM-1, TICAM-2 and TIRAP might have co-evolved with the TLR3/22 antivirus signaling, the LPS-specific TLR4 signaling and the Gram-positive bacteria-induced TLR2 signaling pathways, respectively. Our results are valuable contributions to the understanding of TICAM/TIRAP evolutiona...

Comparative study of tumorigenesis and tumor immunity in invertebrates and nonmammalian vertebrates.
Abstract
I will present evidence of neoplasia and invasive malignancy, as well as tumor immunity in invertebrates and nonmammalian vertebrates. I will also present a comparative and evolutionary view of the complex interactions between neoplasia and the host immune system. Overall, I wish to go beyond the to...

Midline signaling and evolution of the forebrain in chordates: a focus on the lamprey Hedgehog case.
Abstract
We have used lampreys to investigate the possibility that embryonic midline signaling systems have been a driving force for the evolution of the forebrain in vertebrates. We have focused on Sonic Hedgehog/Hedgehog (Shh/Hh) signaling. In this article, we first review and summarize our recent work on...

We provide an overview of existing and ongoing comparative studies of the role of the cerebellum in primate behavior. In particular, we discuss evidence that great apes show greater cerebellar relative size than monkeys and that such interspecific difference is mainly explained by growth of the late...

Abstract
We review the evidence for the presence of sleep states in non-mammalian species including zebrafish (Danio rerio), fruitflies (Drosophila melanogaster) and roundworms (Caenorhabditis elegans). We describe conserved sleep-regulatory molecular pathways with a focus on cAMP and epidermal growth factor...

Abstract
Computational model for airflow through the upper airway of a horse was developed. Previous flow models for human airway do not hold true for horses due to significant differences in anatomy and the high Reynolds number of flow in the equine airway. Moreover, models that simulate the entire respirat...

Abstract
The natriuretic peptide (NP) family is a seemingly ubiquitous sodium and volume reducing endocrine system of predominantly cardiac origin. Members of the NP system include ANP, BNP, CNP, VNP, their guanylate cyclase (GC)-linked receptors (NPR-A and NPR-B), and clearance receptor (NPR-C). Through the...

Abstract
While traditional measures (e.g., maximum range of motion) grossly detected asymmetries due to bracing, these new analyses identified significant regions of asymmetry. Knee-bracing affected the knee during mid-swing, but also increased ankle asymmetry during both terminal stance and mid-swing and hi...

This review uses the current morphological evidence to evaluate the facial morphology of the hypothetical last common ancestor (LCA) of the chimpanzee/bonobo (panin) and human (hominin) lineages.

Abstract
Corticosteroids are important mediators of homeostasis and stress, and exert their effects via two transcription-factor receptors, mineralocorticoid receptor (MR) and glucocorticoid receptor (GR). Both receptors are expressed in the brain in a region-specific manner, and regulate neuroendocrine and...

The genomes of over a dozen placental mammal species are now publicly available. These genome sequences have the potential to provide insight into the development and evolution of the placenta. In particular, the variable anatomy of the placenta has likely been affected by natural selection on the g...

We explore the extent of dietary niche separation amongst these taxa using stable isotope (13C/12C, 18O/16O) and trace-element (Sr, Ba, Ca) analyses of fossil tooth enamel. In particular we searched for evidence of subtle niche separation between the more closely related, morphologically similar tax...

Abstract
Since the time of Muybridge and Marey in the last half of the nineteenth century, studies of animal movement have relied on some form of high-speed or stop-action imaging to permit analysis of appendage and body motion. In the past ten years, the advent of megapixel-resolution high-speed digital ima...

Insulin induces protein accretion by stimulating protein synthesis and inhibiting proteolysis. However, the mechanisms of regulation of protein metabolism by insulin are complex and still not completely understood. The use of approaches combining hyperinsulinemic clamp and isotopic methods, or measu...

Abstract
We determined that the Y. enterocolitica rovA (rovA(Yent)) promoter is weaker than the Y. pseudotuberculosis promoter. However, despite the missing H-NS/RovA binding site in the rovA(Yent) promoter, H-NS and RovA are still involved in the regulation of rovA(Yent). DNA binding studies suggest that H-...

Implicit in this definition is the use of transgenics and reverse genetics to manipulate gene function in a cell-specific manner; this in...

Successful reconstruction of any aspect of human evolution ideally requires broad-based comparisons with other primates, as recognition of general principles provides a more reliable foundation for inference. Indeed, in many cases it is necessary to conduct comparisons with other placental mammals t...

Abstract
We show that Drierite has an affinity for CO(2) when new and completely anhydrous, and therefore it has an adverse effect on the washout characteristics of this gas. Exposing the Drierite to room air reduces this CO(2) affinity, and a 2-min exposure at 20 degrees Celsius and 50% relative humidity is...

We must guard against fractionation of effort and purpose. Increasingly available molecular methods are seductive in encouraging work on model species and in employing these species in place of more appropriate comparative models. Concomitantly, the comparative approach is reaching out beyond the in...

Abstract
Superfast muscles of vertebrates power sound production. The fastest, the swimbladder muscle of toadfish, generates mechanical power at frequencies in excess of 200 Hz. To operate at these frequencies, the speed of relaxation has had to increase approximately 50-fold. This increase is accomplished b...

Every field of biology has its assumptions, but when they grow to be dogma, they can become constraining. This essay presents data-based challenges to several prominent assumptions of developmental physiologists. The ubiquity of allometry is such an assumption, yet animal development is characterize...
