Abstract Disaster response robots are expected to perform complicated tasks such as traveling over unstable terrain, climbing slippery steps, and removing heavy debris. To complete safely, the must obtain not only visual-perceptual information (VPI) surface shape but also haptic-perceptual (HPI) friction of objects in environments. VPI can be obtained from laser sensors cameras. In contrast, HP...

Novel methodology is presented for indexing the relative potential of hosts to function as resources. A Host Potential Index (HPI) was developed as a practical framework to express relative host potential based on combining results from one or more independent studies, such as those examining host selection, utilization, and physiological development of the organism resourcing the host. Several...

PURPOSE Retinitis pigmentosa (RP) is a heterogeneous group of inherited conditions that lead to blindness and for which there is no effective therapy. Apoptosis of photoreceptors is a common feature in animal models of the disease. Thus, the authors studied the therapeutic potential of proinsulin, an antiapoptotic molecule active during retinal development. METHODS Transgenic mice expressing ...

Peste des petits ruminants virus (PPRV), the etiological agent of peste des petits ruminants (PPR), causes an acute or subacute disease in small ruminants. Although abortion is observed in an unusually large proportion of pregnant goats during outbreaks of PPR, the pathogenic mechanism underlying remains unclear. Here, the gene expression profile of caprine endometrial epithelial cells (EECs) i...

Defender against cell death (DAD) genes are known to function as negative regulators of cell death in animals. In plants, DAD orthologs are conserved but their role in cell death regulation is not well understood. Here, we report the characterization of the TaDAD2 gene in wheat. The predicted amino acid sequence of TaDAD2 contains typical structural features of DAD proteins, including a signal ...

Coxiella burnetii is an obligate intracellular bacterial pathogen that directs biogenesis of a lysosome-like, parasitophorous vacuole in mammalian cells. We recently reported that C. burnetii inhibits apoptotic cell death in macrophages, presumably as a mechanism to sustain the host for completion of its lengthy infectious cycle. In the current study, we further investigated C. burnetii manipul...

Five previously analyzed white spot syndrome virus (WSSV) strains from northwest Mexico, differing in their genome architecture as well virulence, were selected (high virulence JP and LG strains; moderate GVE DIV low LC10 strain) to evaluate pathogenesis response vitro. Expression of phagocytosis-activating protein PAP, manganese superoxide dismutase MnSOD peroxiredoxin PRX, two genes immediate...

A study of histopathological changes due to the infection of Helicoverpa armigera Nuclear Polyhedrosis Virus (HANPV) in the third instar larvae of H. armigera at 24, 48, 72 and 96 hour interval was carried out in the laboratory. The histopathalogical sequential changes in the post infected H. armigera revealed the presence of infected area in the midgut epithelium at 72 hpi (hour post infection...

following experimental inoculation of 3-week-old turkeys with different titres (106, 104, 103, 102 and 101 egg infectious dose (eid50)) of a/ostrich/italy/984/2000 h7n1 highly pathogenic avian influenza virus (hpaiv), the selected tissues and organs were examined for pathological changes. tissue samples from different organs that obtained from dead and sacrificed birds were fixed in 10% neutral...
