RNA-mediated transcriptional silencing prevents deleterious effects of transposon activity and controls the expression of protein-coding genes. It involves long noncoding RNAs (lncRNAs). In Arabidopsis thaliana, some of those lncRNAs are produced by a specialized RNA Polymerase V (Pol V). The mechanism by which lncRNAs affect chromatin structure and mRNA production remains mostly unknown. Here ...

Heterozygous germline mutations in components of switch/sucrose nonfermenting (SWI/SNF) chromatin remodeling complexes were recently identified in patients with non-syndromic intellectual disability, Coffin-Siris syndrome and Nicolaides-Baraitser syndrome. The common denominator of the phenotype of these patients is severe intellectual disability and speech delay. Somatic and germline mutations...

BACKGROUND AND PURPOSE The differentiation between Parkinson disease and atypical parkinsonian syndromes can be challenging in clinical practice, especially in early disease stages. Brain MR imaging can help to increase certainty about the diagnosis. Our goal was to evaluate the added value of SWI in relation to conventional 3T brain MR imaging for the diagnostic work-up of early-stage parkinso...

BACKGROUND Almost one third of women suffer continuous lower back pain during labour. Evidence from three systematic reviews demonstrates that sterile water injections (SWI) provide statistically and clinically significant pain relief in women experiencing continuous lower back pain during labour. The most effective technique to administer SWI is yet to be determined. Therefore, the aim of this...

BACKGROUND In Saccharomyces cerevisiae, three out of the four histone gene pairs (HTA1-HTB1, HHT1-HHF1, and HHT2-HHF2) are regulated by the HIR co-repressor complex. The histone chaperone Rtt106 has recently been shown to be present at these histone gene loci throughout the cell cycle in a HIR- and Asf1-dependent manner and involved in their transcriptional repression. The SWI/SNF and RSC chrom...

BACKGROUND End-stage renal disease and dialysis patients have a higher incidence of renal cell carcinoma (RCC) than the general population. Preoperatively evaluating the biological behavior of RCC plays an important role in treatment decision-making. Susceptibility-weighted imaging (SWI) can visualize the distribution of microvenous structures and hemorrhage without contrast materials. PURPOS...

The SWI/SNF chromatin-remodeling family contains various protein complexes, which regulate gene expression during cellular development and influence DNA damage response in an ATP- and complex-dependent manner, of which details remain elusive. Recent human genome sequencing of various cancer cells revealed frequent mutations in SWI/SNF factors, especially ARID1A, a variant subunit in the BRG1-as...

BACKGROUND Coronary artery by-pass grafting (CABG) remains the optimal strategy in achieving complete revascularization in patients with complex coronary artery disease. However, sternal wound infections (SWI), especially deep SWI are potentially severe complications to the surgery. At the department of cardiothoracic surgery in Uppsala University Hospital a gradual increase in all types of SWI...

The National Waqf Body (BWI) and Ministry of Finance (MoF) have implemented a model called Cash Linked Sukuk (CWLS) issued the Government Indonesia (Islamic securities) namely (SWI) in 2020. intention behind applying CWLS is to accelerate waqf as one Islamic social funds particularly, optimize collection cash with securities serve public at same time diversify sovereign (Sukuk) financial market...

We retrospectively identified 9 consecutive children, 3 males and 6 females (age 5.2 ± 6.3 years, range 1 day to 18 years), with known or suspected AVGs who underwent MR imaging, including SWI, at our institution between January 2007 and March 2011. On the SWI sequence, arterialized blood flow was considered to be present in the vein of Galen or its tributaries when these showed abnormal signal...
