The three-dimensional (3-D) form and the interrelationship of peroxisomes (Po) in the model of regenerating rat liver after partial hepatectomy were studied by computer-assisted 3-D reconstruction of serial ultrathin sections. Po were labeled cytochemically for either catalase, which stains them all uniformly, or for D-amino acid oxidase (DAA-OX), which gives a heterogeneous reaction with light...

In order to confirm the relationship between sex hormone administration and glutathione-peroxidase (GSH-PO) in the rat ventral prostate, the levels of GSH-PO mRNA, GSH-PO activitM and Iipid peroxide (TBA) value in the ventral prostate were investigated. Male Cij:CD(SD)IGS rats were divided into six experimental groups. Group 1 consisted o'f intact controls. In group 2, rats were sacrificed two ...

SILVESTER, W. B., WHITBECK, J . , SILVESTER, J. K., and TORREY, J. G. 1988. Growth, nodule morphology, and nitrogenase activity of Myrica gale with roots grown at various oxygen levels. Can. J . Bot. 66: 17621771. Myrica gale L. plants were inoculated with Frankia strain HFP M'gI5 and grown for 28 days with root systems exposed to 2, 5, 10, 21, and 40 kPa 0,. Plant growth was similar under all ...

Locally partial-ordered spaces (local po-spaces) have been used to model concurrent systems. We provide equivalences for these spaces by constructing a model category containing the category of local po-spaces. We show the category of simplicial presheaves on local po-spaces can be given Jardine’s model structure, in which we identify the weak equivalences between local po-spaces. In the proces...

Li₃V₂(PO₄)3-xBrx/carbon (x = 0.08, 0.14, 0.20, and 0.26) composites as cathode materials for lithium-ion batteries were prepared through partially substituting PO₄3- with Br-, via a rheological phase reaction method. The crystal structure and morphology of the as-prepared composites were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), and electrochemical propert...

Testicular function and associated testosterone concentration decline with advancing age, and an impaired O₂ supply may contribute, in part, to this reduction. We hypothesized that there would be a reduced microvascular Po₂ (Po₂(m)) in the testes from aged rats, and this reduced Po₂(m) would be associated with impaired vasomotor control in isolated resistance arterioles. In addition, given the ...

Our objective was to determine whether chronic vagus nerve stimulation (VNS) mitigates pressure overload (PO)-induced remodeling of the cardioneural interface. Guinea pigs (n = 48) were randomized to right or left cervical vagus (RCV or LCV) implant. After 2 wk, chronic left ventricular PO was induced by partial (15-20%) aortic constriction. Of the 31 animals surviving PO induction, 10 were ran...

The development of probabilistic inference techniques has made considerable progress in recent years, in particular with respect to exploiting the structure (e.g., factored, hierarchical or relational) of discrete and continuous problem domains. We show that these techniques can be used also for solving Markov Decision Processes (MDPs) or partial observable MDPs (POMDPs) when formulated in term...
