The goal of this procedure was to harvest the #4 abdominal mammary glands from female nulliparous mice in order to assess ECM expression and ductal architecture. Here, a small pocket below the skin was created using Mayo scissors, allowing separation of the glands within the subcutaneous tissue from the underlying peritoneum. Visualization of the glands was aided by the use of 3.5x-R surgical micro loupes. The pelt was inverted and pinned back allowing identification of the intact mammary fat pads. Each of the #4 abdominal glands was bluntly dissected by sliding the scalpel blade laterally between the subcutaneous layer and the glands...

BACKGROUND: Systemic light chain amyloidosis (AL) is characterized by the extracellular deposition of amyloid fibrils. Transthoracic echocardiography is the modality of choice to assess cardiac function in patients with AL. Whereas left ventricular (LV) function has been well studied in this patient population, data regarding the value of left atrial (LA) function in AL patients are lacking. In this study, we aim to examine the impact of LA volumes and function on survival in AL patients as assessed by real-time 3D echocardiography...

Yaf9 is an integral part of the NuA4 acetyltransferase and the SWR1 chromatin remodeling complexes. Here, we show that Yaf9 associates with acetylated histone H3 with high preference for H3K27ac. The crystal structure of the Yaf9 YEATS domain bound to the H3K27ac peptide reveals that the sequence C-terminal to K27ac stabilizes the complex. The side chain of K27ac inserts between two aromatic residues, mutation of which abrogates the interaction in vitro and leads in vivo to phenotypes similar to YAF9 deletion, including loss of SWR1-dependent incorporation of variant histone H2A...

To better understand the innate immune response to Vibrio cholerae infection, we tracked gene expression in the duodenal mucosa of eleven Bangladeshi adults with cholera, using biopsies obtained immediately after rehydration and at 30 and 180 days later. We identified differentially expressed genes and performed an analysis to predict differentially regulated pathways and upstream regulators. During acute cholera, there was a broad increase in the expression of genes associated with innate immunity, including activation of the NF-κB, MAPK, and TLR-mediated signaling pathways, which unexpectedly persisted even 30 days after infection...

Although health care lags behind many other industries in adopting social media as part of a business strategy, the Mayo Clinic recognized the importance of these applications more than a decade ago. In addition to typical media relations and marketing tactics, the Mayo Clinic has successfully used social media as part of an overall program to support the strategic imperatives of the institution.

The Notch pathway is a highly conserved juxtacrine signaling mechanism that is important for many cellular processes during development, including differentiation and proliferation. While Notch is important during ovarian follicle formation and early development, its functions during the gonadotropin-dependent stages of follicle development are largely unexplored. We observed positive regulation of Notch activity and expression of Notch ligands and receptors following activation of the LH-receptor in prepubertal mouse ovary...
