This paper discusses several rapid site characterization (RSC) technologies that can be used at marine sediment sites, including X-ray fluorescence (XRF) for metals, ultraviolet fluorescence (UVF) for polycyclic aromatic hydrocarbons, QwikSed bioassay for assessing toxicity, and other techniques. Examples are provided to illustrate the efficacy of applying RSC tools to different stages of the E...

The yeast "remodels the structure of chromatin" (RSC) complex is a multi-subunit "switching deficient/sucrose non-fermenting" type ATP-dependent nucleosome remodeler, with human counterparts that are well-established tumor suppressors. Using temperature-inducible degron fusions of all the essential RSC subunits, we set out to map RSC requirement as a function of the mitotic cell cycle. We found...

In a comparison of 1,368 positive blood cultures, a vented Roche Septi-Chek (V-RSC) blood culture bottle was superior to an unvented tryptic soy broth-containing bottle (Difco) for the recovery of all aerobic and facultatively anaerobic microorganisms. Anaerobic bacteria were recovered more frequently and earlier in the unvented tryptic soy broth-containing bottle. A separate comparison of 529 ...

Radiotherapy is widely applied for locally advanced rectal cancer (RC) to improve both local control and long-term outcomes. However, the efficacy of radiotherapy for rectosigmoid junction cancer (RSC) is still undetermined. Here, we identified 10074 patients who were diagnosed with locally advanced RSC from Surveillance, Epidemiology, and End-Results (SEER) cancer registry. These patients were...

The 'remodels structure of chromatin' (RSC) complex is an essential chromatin remodeling factor that is required for the control of several processes including transcription, repair and replication. The ability of RSC to relocate centrally positioned mononucleosomes at the end of nucleosomal DNA is firmly established, but the data on RSC action on oligo-nucleosomal templates remains still scarc...

There is a close relationship between histone acetylation and ATP-dependent chromatin remodeling that is not fully understood. We show that acetylation of histone H3 tails affects SWI/SNF (mating type switching/ sucrose non fermenting) and RSC (remodels structure of chromatin) remodeling in several distinct ways. Acetylation of the histone H3 N-terminal tail facilitated recruitment and nucleoso...

BACKGROUND Dia2 is an F-box protein found in the budding yeast, S. cerevisiae. Together with Skp1 and Cul1, Dia2 forms the substrate-determining part of an E3 ubiquitin ligase complex, otherwise known as the SCF. Dia2 has previously been implicated in the control of replication and genome stability via its interaction with the replisome progression complex. PRINCIPAL FINDINGS We identified co...

A novel 15-subunit complex with the capacity to remodel the structure of chromatin, termed RSC, has been isolated from S. cerevisiae on the basis of homology to the SWI/SNF complex. At least three RSC subunits are related to SWI/SNF polypeptides: Sth1p, Rsc6p, and Rsc8p are significantly similar to Swi2/Snf2p, Swp73p, and Swi3p, respectively, and were identified by mass spectrometric and sequen...

Root-surface caries (RSC) has been recognized as a specific and important dental disease. Significant advances have been made in the pathology and microbiology of RSC, and the need to standardize the guidelines for recording RSC data has been recognized. Researchers have emphasized the increasing impact RSC will have on the geriatric population, especially since the methods to treat and prevent...

The RSC Working Paper Series is intended to aid the rapid distribution of work in progress, research findings and special lectures by researchers and associates of the RSC. Papers aim to stimulate discussion among the worldwide community of scholars, policymakers and practitioners. They are distributed free of charge in PDF format via the RSC website. Bound hard copies of the working papers may...
