Neutrophils play an active role in the control of infections caused by intracellular pathogens such as Leishmania. In the present study, we investigated the effect of neutrophil depletion at the time of Leishmania braziliensis infection of BALB/c mice and how neutrophils interact with the infected macrophage to promote parasite elimination. The in vivo depletion of neutrophils led to a signific...

Nobuchika Sakata Human Interface Laboratory Division of Systems Science and Applied Informatics Osaka University, Japan [email protected] Abstract In this research, we explore using pointing and drawing in a remote collaboration system. Our application allows a local user with a tablet to communicate with a remote expert on a desktop computer. We compared performance in four condition...

Bacterial infections are a serious problem in aquaculture since they can result in massive mortalities in farmed fish and invertebrates. Vibriosis is one of the most common diseases in marine aquaculture hatcheries and its causative agents are bacteria of the genus Vibrio mostly entering larval rearing water through live feeds, such as Artemia and rotifers. The pathogenic Vibrio alginolyticus s...

Trichomonas vaginalis secretes a number of proteases which are suspected to be the cause of pathogenesis; however, little is understood how they manipulate host cells. The mammalian target of rapamycin (mTOR) regulates cell growth, cell proliferation, cell motility, cell survival, protein synthesis, and transcription. We detected various types of metalloproteinases including GP63 protein from T...

The latest professional Karaoke system released in Japan has no ASIC for sound synthesis and effects processing, but instead a small group of load-sharing DSP chips that cooperatively handle the varied and dynamically varying tasks of complex high-quality audio performance. The software-only system is a first for the professional audio industry, heralding a new generation of downloadable and ta...

A considerable effort is currently underway to develop a malaria vaccine based on live Plasmodium falciparum sporozoites. The first requisite of a sporozoite vaccine is the guarantee of parasite arrest prior to the onset of the pathogenic blood stage. Immunisation with genetically attenuated parasites (GAP) that arrest in the liver forms a promising approach. Work in this thesis describes the d...

This paper presents a live-video service using multicast in wireless network. The switching/multicast agent (SMA) in this system provides multicast for effective use of network resources in WLAN and reduces the load of video server and access points(AP). Also, the SMA and AP support a handover mechanism for moving mobile nodes(MN) using identification number(ID#) of AP (AP_#) that the MNs are v...

The emergence of the Internet as a pervasive communication medium, and the widespread availability of digital video technology have led to the rise of several networked streaming media applications such as live video broadcasts, distance education and corporate telecasts. This paper studies the traffic associated with two major categories of streaming content on-demand streaming of pre-recorded...
