Boxing is one of the most popular striking combat sports in the world. The aim of this review was to present data concerning performance analysis (time-motion and technical/tactical analysis) and physiological responses (i.e., blood lactate concentration [BLC], heart rate and/or oxygen consumption) during novice and elite male simulated and official amateur boxing competitions in any age category. The present review shows that boxing competition is a high-intensity intermittent striking combat sport. Typically, the activity-to-rest ratio was higher in elite (18:1) than novice (9:1) boxers and significant differences were observed between rounds (1 round=16:1, 2 round=8:1, and 3 round=6:1) in novice boxers...

Rats are predators of mice in nature. Nevertheless, it is a common practice to house mice and rats in a same room in some laboratories. In this study, we investigated the behavioral and physiological responsively of mice in long-term co-species housing conditions. Twenty-four male mice were randomly assigned to their original raising room (control) or a rat room (co-species-housed) for more than 6 weeks. In the open-field and light-dark box tests, the behaviors of the co-species-housed mice and controls were not different...

High mobility group proteins (HMGs) are the second most abundant chromatin proteins and exert global genomic functions in the establishment of active or inactive chromatin domains. Through interaction with nucleosomes, transcription factors, nucleosome-remodeling machines and histones, the HMGs family proteins contribute to the fine tuning of transcription in response to rapid environmental changes. Mammalian high mobility group Bs (HMGBs) are characterized by two tandem HMG box domains followed by a long acidic tail...

Animals live in complex environments where multiple cues can provide consistent or conflicting information about how to behave most effectively. Previous research has described how animals combine information with qualitative combination rules; the goal of this article was to quantify the combination rule used by rats when 2 previously trained stimuli of separate modalities were presented simultaneously. Rats in a lever box were trained with 2 stimuli (light and tone) assigned given probabilities of food before they were tested in compound...

BACKGROUND & AIMS: The alpha subunit of the heterotrimeric G stimulatory protein (Gsa), encoded by the guanine nucleotide binding protein, alpha stimulating gene (Gnas, in mice), is expressed ubiquitously and mediates receptor-stimulated production of cyclic adenosine monophosphate (cAMP) and activation of the protein kinase A signaling pathway. We investigated the roles of Gsa in vivo in smooth muscle cells of mice. METHODS: We performed studies of mice with Cre recombinase-mediated disruption of Gnas in smooth muscle cells (Gsa(SMKO) and SM22-CreER(T2), induced in adult mice by tamoxifen)...

This paper presents a method, called AOGTracker, for simultaneously tracking, learning and parsing (TLP) of unknown objects in video sequences with a hierarchical and compositional And-Or graph (AOG) representation. The TLP method is formulated in the Bayesian framework with a spatial and a temporal dynamic programming (DP) algorithms inferring object bounding boxes on-the-fly. During online learning, the AOG is discriminatively learned using latent SVM [1] to account for appearance (e.g., lighting and partial occlusion) and structural (e...

Asbestos exposure leads to malignant mesothelioma (MM), a deadly neoplasm of mesothelial cells of various locations. Although there is no doubt about the role of asbestos in MM tumorigenesis, mechanisms are still not well explored. Recently, our group demonstrated that asbestos causes inflammasome priming and activation in mesothelial cells, which in part is dependent on oxidative stress. Our current study sheds light on yet another mechanism of inflammasome activation by asbestos. Here we show the role of actin polymerization in asbestos-induced activation of the nod-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome...

In humans, alterations in thyroid hormone signalling are associated with mood and anxiety disorders, but the neural mechanisms underlying such association are poorly understood. The present study investigates the involvement of neuronal thyroid hormone receptor α (TRα) in anxiety, using mouse genetics and Cre/loxP technology to specifically alter TRα signalling in neurons. We evaluated the behaviour of mice expressing a dominant negative, neuron-specific mutation of TRα (TRα(AMI)/Cre3 mice), using the elevated-plus maze, light-dark box and open-field tests...

Correct spatial and temporal control of cell proliferation is of fundamental importance for tissue homeostasis. Its deregulation has been associated with several pathological conditions. In common with almost every aspect of plant and animal biology, cell proliferation is dominated by day-night rhythms generated by the circadian clock. However, our understanding of the crosstalk between the core clock and cell cycle control mechanisms remains incomplete. In this study, using zebrafish as a vertebrate model system, we show that the nuclear localization of the Y-box binding protein 1 (YB-1), a regulator of cyclin expression and a hallmark of certain cancers, is robustly regulated by the circadian clock...

Binge eating disorder and alcohol use disorder (AUD) frequently co-occur in the presence of other psychiatric conditions. Data suggest that binge eating engages similar behavioral and neurochemical processes common to AUD, which might contribute to the etiology or maintenance of alcoholism. However, it is unclear how binge feeding behavior and alcohol intake interact to promote initiation or maintenance of AUD. We investigated the impact of binge-like feeding on alcohol intake and anxiety-like behavior in male Long Evans rats...

: In 1986, we reported a multiple biological effect of IL-1 including immunological, inflammatory, and tumor killing activity. Since then other IL-1 family cytokines have been discovered, some with inflammatory and other with anti-inflammatory activity. In this review article, we speculate on the possible inhibitory effect of IL-37 in the light of new findings. IL-37, formerly termed IL-1 family member 7 (IL-1F7), binding IL-18 receptor α chain, acts as a cytokine with intracellular as well as extracellular functionality and as a natural inhibitor of immune responses and inflammation...
