UNLABELLED Thermus thermophilus HB8 expresses silica-induced protein (Sip) when cultured in medium containing supersaturated silicic acids. Using genomic information, Sip was identified as a Fe(3+)-binding ABC transporter. Detection of a 1-kb hybridized band in Northern analysis revealed that sip transcription is monocistronic and that sip has its own terminator and promoter. The sequence of th...

We previously reported the identification of small serine/threonine kinase (SSTK) that is expressed in postmeiotic germ cells, associates with HSP90, and is indispensable for male fertility. Sperm from SSTK-null mice cannot fertilize eggs in vitro and are incapable of fusing with eggs that lack zona pellucida. Here, using the yeast two-hybrid screen, we have discovered a novel SSTK-interacting ...

OBJECTIVE Although the Short Index of Problems (SIP) is often used, little is known about the psychometric properties of the SIP in special populations. The present study seeks to determine the following: (1) whether it is possible to substitute items to enhance the psychometric properties of the SIP and (2) whether the SIP, or improved scale, is as sensitive as the Drinker Inventory of Consequ...

The Hsp90 chaperone activity is tightly regulated by interaction with many co-chaperones. Since CacyBP/SIP shares some sequence homology with a known Hsp90 co-chaperone, Sgt1, in this work we performed a set of experiments in order to verify whether CacyBP/SIP can interact with Hsp90. By applying the immunoprecipitation assay we have found that CacyBP/SIP binds to Hsp90 and that the middle (M) ...

Voice over Internet Protocol (VoIP) and its underlying Session Initiation (SIP) are widely deployed technologies since they provide an efficient fast means of both voice data communication a single network. However, in spite their advantages, also have security threats due to the inherent vulnerabilities (IP) that can potentially be exploited by hackers. This study introduces novel defense mech...

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

VoIP service is the transmission of voice data using SIP protocol on an IP-based network. The SIP protocol has many advantages, such as providing IP-based voice communication and multimedia service with low communication cost. Therefore, the SIP protocol disseminated quickly. However, SIP protocol exposes new forms of vulnerabilities to malicious attacks, such as message flooding attack. It als...

The wireless industry trend toward higher integration and RF component miniaturization has been driving ongoing technology innovations, especially for substrate, interconnect, and packaging technologies. RF Systemin-Package (RF SiP) is one of those leading technology innovations. RF SiP is usually a sub-system unit, and it typically consists of multiple dies with or without passive components g...

Purpose Despite the fact that user participation (UP) has been highlighted as an important aspect in innovation, previous findings on its relationship with service innovation performance (SIP) are inconsistent. This study aims to investigate relationships among UP, knowledge management capability (KMC) and SIP, especially digital age, inspired by theories of knowledge-based absorptive capacity....
