Mosaic fungal individuals have the potential to evolve within a single generation.

Although cells of mushroom-producing fungi typically contain paired haploid nuclei (n + n), most Armillaria gallica vegetative cells are uninucleate. As vegetative nuclei are produced by fusions of paired haploid nuclei, they are thought to be diploid (2n). Here we report finding haploid vegetative nuclei in A.

The Effectiveness of Standardized Handoff Tool Interventions During Inter- and Intra-facility Care Transitions on Patient-Related Outcomes: A Systematic Review.

Improving physician handoffs is a patient safety priority. The authors hypothesize that standardized handoff interventions during care transitions improve patient-related outcome measures. PubMed, Cochrane, PsycINFO, CINAHL, Embase, and Web of Science were searched for publications from 2000 to May 2016.

Age-dependent loss of MMP-3 in Hutchinson-Gilford progeria syndrome.

Hutchinson-Gilford progeria syndrome (HGPS) is a rare, progressive segmental premature aging disease that includes scleroderma-like skin, progressive joint contracture, and atherosclerosis. Affected individuals die prematurely of heart attacks or strokes. Extracellular matrix dysregulation is implicated as a factor in disease progression.

Effects of metalloproteinase inhibition in a murine model of renal ischemia-reperfusion injury.

Ischemia-reperfusion injury (IRI) is a leading cause of acute tubular necrosis (ATN) and delayed graft function in transplanted organs. Up-regulation of matrix metalloproteinases (MMPs) propagates the microinflammatory response that drives IRI. This study sought to determine the specific effects of Marimastat (Vernalis, BB-2516), a broad spectrum MMP and TNF-alpha-converting enzyme inhibitor, on IRI-induced ATN.

Lipocalin 2 promotes breast cancer progression.

Here, we report that lipocalin 2 (Lcn2) promotes breast cancer progression, and we identify the mechanisms underlying this function. We first found that Lcn2 levels were consistently associated with invasive breast cancer in human tissue and urine samples. To investigate the function of Lcn2 in breast cancer progression, Lcn2 was overexpressed in human breast cancer cells and was found to up-regulate mesenchymal markers, including vimentin and fibronectin, down-regulate the epithelial marker E-cadherin, and significantly increase cell motility and invasiveness.

Acute hydrocephalus secondary to obstruction of the foramen of monro and cerebral aqueduct caused by a choroid plexus cyst in the lateral ventricle. Case report.

Choroid plexus cysts are common and typically asymptomatic abnormal folds of the epithelial lining of the choroid plexus. Rarely, these cysts may gradually enlarge and cause outflow obstruction of cerebrospinal fluid. The authors present a case of a large choroid plexus cyst causing acute hydrocephalus in a previously healthy 2-year-old boy.
