Abstract The efficiency of voloxidation mixed nitride uranium–plutonium spent nuclear fuel (MNUP SNF) for the separation composition from rod cladding and removal 3 H 14 C was estimated. It shown that completeness SNF under optimal conditions is at level 98–99%. residual content tritium in voloxidized does not exceed 0.2% its original sample; radiocarbon removed by 98%.

Many studies have established that the Swi/Snf family of chromatin-remodeling complexes activate transcription. Recent reports have suggested the possibility that these complexes can also repress transcription. We now present chromatin immunoprecipitation evidence that the Swi/Snf complex of Saccharomyces cerevisiae directly represses transcription of the SER3 gene. Consistent with its role in ...

Abstract The chromatin remodeler complexes mammalian SWI/SNF (SWItch/Sucrose Non-Fermentable) are altered in more than 40% of cancers and involved therapeutic resistance. In children,SMARCB1 is mutated 95% rhabdoid tumors, the remaining 5% present mutations SMARCA4. These tumors typically identified children younger three years old have a very poor prognosis with survival under one year followi...

Throughout life, patients with multiple sclerosis (MS) require increasing levels of support, rehabilitative services, and eventual skilled nursing facility (SNF) care. There are concerns that access to SNF care for MS patients is limited because of perceived higher costs of their care. This study compares costs of caring for an MS patient versus those of a typical SNF patient. We merged SNF cos...

Chromatin, a combination of nucleosomes and linker histones, inhibits transcription by blocking polymerase movement and access of factors to DNA. ATP-dependent remodeling complexes such as SWI/SNF and RSC alter chromatin structure to increase or decrease this repression. To further our understanding of how human SWI/SNF (hSWI/SNF) "remodels" chromatin we examined the octamer location, nature, a...

Normal form theory is one of the most power tools for the study of nonlinear di.erential equations, in particular, for stability and bifurcation analysis. Recently, many researchers have paid attention to further reduction of conventional normal forms (CNF) to so called the simplest normal form (SNF). However, the computation of normal forms has been restricted to systems which do not contain p...

BACKGROUND Although many older adults require skilled nursing facility (SNF) care after acute hospitalization, it is unclear whether internal medicine residents have sufficient knowledge of the care that can be provided at this site. METHODS We developed a 10-item multiple choice pre-test that assessed knowledge of the definition of a SNF, SNF staffing requirements, and SNF services provided ...

BACKGROUND In the last 6 months of life, many older adults will experience a hospitalization, followed by a transfer to a skilled nursing facility (SNF) for additional care. We sought to examine patterns of Medicare posthospitalization SNF use in the last 6 months of life. METHODS We used data from the Health and Retirement Study, a longitudinal survey of older adults, linked to Medicare clai...
