Behçet's disease (BD) is a heterogeneous multi-organ disorder in search of a unified pathophysiological theory and classification. The disease frequently has overlapping features resembling other disease clusters, such as vasculitides, spondyloarthritides and thrombophilias with similar genetic risk variants, namely HLA-B*51, ERAP1, IL-10, IL-23R. Many of the BD manifestations, such as unprovoked recurrent episodes of inflammation and increased expression of IL-1, IL-6 and TNFα, overlap with those of the hereditary monogenic autoinflammatory syndromes, positioning BD at the crossroads between autoimmune and autoinflammatory syndromes. BD-like disease associates with various inborn errors of immunity, including familial Mediterranean fever, conditions related to dysregulated NF-κB activation (eg TNFAIP3, NFKB1, OTULIN, RELA, IKBKG) and either constitutional trisomy 8 or acquired trisomy 8 in myelodysplastic syndromes. We review here the recent advances in the immunopathology of BD, BD-like diseases and the NF-κB pathway suggesting new elements in the elusive BD etiopathogenesis.

To explore newly graduated registered nurses' experiences and how they manage complex patient situations.

Newly graduated registered nurses' working in acute care hospital settings are challenged by managing complex patient situations in rapidly changing clinical contexts involving increased patient acuity, comorbidities and staffing shortages.

Qualitative study design.

Data were collected using focus groups interviews of a total of 16 newly graduated registered nurses with clinical work experience of 6months of direct patient care in an acute care hospital setting. Analyses were conducted using qualitative content analysis. COREQ reporting guidelines were used.

The analysis resulted in the overarching theme "Not being sufficiently prepared and supported to meet responsibilities and demands." The theme included three categories "Responsibility is not in proportion to competence," "Lack of medical competence and experience complicates patient safety" and "Strives for control to manage and organise nursing care."

The results show that newly graduated registered nurses' are not sufficiently supported for the level of responsibility and the demands placed on them when providing nursing in complex patient situations in acute care hospital settings. If they are given sole responsibility for multiple complex patient situations, patient safety may be compromised.

Special attention need to be paid to NGRNs support to medical competence in the areas of assessing, planning, prioritizing, leading, and distributing nursing care in daily clinical settings for at least their first year of professional work.

The dysferlin gene or the DYSF gene encodes the Ca

-dependent phospholipid-binding protein dysferlin, which belongs to the ferlin family and is associated with muscle membrane regeneration and repair. Variants in the DYSF gene are responsible for limb-girdle muscular dystrophy type 2B (LGMD2B), also called limb-girdle muscular dystrophy recessive 2 (LGMDR2), a rare subtype of muscular dystrophy involving progressive muscle weakness and atrophy. FTY720 ic50 The present study aimed to identify the variants responsible for the clinical symptoms of a Chinese patient with limb girdle muscular dystrophies (LGMDs) and to explore the genotype-phenotype associations of LGMD2B.

A series of clinical examinations, including blood tests, magnetic resonance imaging scans for the lower legs, electromyography and muscle biopsy, was performed on the proband diagnosed with muscular dystrophies. Whole exome sequencing was conducted to detect the causative variants, followed by Sanger sequencing to validate these variants.

We identirates the development of a prenatal diagnosis.

The present study broadens our understanding of the mutational spectrum of the DYSF gene, which provides a deep insight into the pathogenesis of LGMDs and accelerates the development of a prenatal diagnosis.DNA double-strand break (DSB) is one of the most deleterious types of DNA lesions threatening genome integrity. Cells have evolved several exquisite pathways to repair these breaks. Homologous recombination (HR) is an essential DSB repair mechanism that utilizes an intact homologous sequence as a template to repair DSBs with high fidelity. To initiate the HR repair, the 5'-ends of DSBs have to be nucleolytically cleaved by nucleases to generate 3'-single-strand DNA (ssDNA). Exposed 3'-ssDNA recruits the ssDNA binding protein complex RPA to activate the DNA damage checkpoint. RPA is subsequently replaced by Rad51 recombinase to form Rad51 nucleoprotein filament that catalyzes strand invasion and formation of the D-loop. Processing of 5'-ends (called resection) is a crucial step that determines the choice of repair pathways. Here we introduce an assay for monitoring the dynamics of resection at different locations from a site-specific DSB in yeast.Live-cell imaging is widely used by researchers to study cellular dynamics and obtain a deep understanding of cell biological processes. Keeping cells in the proper growing environment and immobilizing the cells are essential for the imaging of live yeast cells. Here we describe a protocol for monitoring cytoophidia in Saccharomyces cerevisiae and Schizosaccharomyces pombe using inverted confocal fluorescence microscopy. This protocol includes yeast culture, sample preparation, fluorescence imaging, and data analysis.The budding yeast is a valuable model system for discovering molecular mechanisms underlying cellular aging. This is due to the ease of performing genetic manipulations in yeast and the vast number of evolutionarily conserved genes that have been found to regulate cellular health and lifespan from yeast to humans. Lifespan assays are an essential tool for examining the effects of these genes on longevity. There are two ways lifespan is measured in yeast replicative lifespan (RLS) and chronological lifespan (CLS). RLS is a measure of how many divisions an individual mother cell will undergo. CLS measures the length of time nondividing cells survive. Previously described CLS assays involved diluting and plating cells of a culture and counting the colonies that arose. While effective, this method is both time and labor intensive. Here, we describe a method for a high-throughput rapid CLS assay that is both time- and cost-efficient.
