Enhancing Patient Outcomes in Aesthetic Breast Implant Procedures Using Proven Antimicrobial Breast Pocket Irrigations: A 20-Year Follow-up.

Background: Capsular contracture (CC) remains the most common complication of implant-based aesthetic and reconstructive breast surgery. With subclinical infection proven to be the primary etiology, antimicrobial breast pocket irrigation has been recommended as the key step to reduce CC but has not been universally adopted.

Objectives: The purpose of this study was to review the rates of CC observed when applying proven antimicrobial breast pocket irrigations.

Intestinal subepithelial myofibroblasts support in vitro and in vivo growth of human small intestinal epithelium.

The intestinal crypt-niche interaction is thought to be essential to the function, maintenance, and proliferation of progenitor stem cells found at the bases of intestinal crypts. These stem cells are constantly renewing the intestinal epithelium by sending differentiated cells from the base of the crypts of Lieberkühn to the villus tips where they slough off into the intestinal lumen. The intestinal niche consists of various cell types, extracellular matrix, and growth factors and surrounds the intestinal progenitor cells.

Fractionation of serum components using nanoporous substrates.

Numerous previously uncharacterized molecules resident within the low molecular weight circulatory proteome may provide a picture of the ongoing pathophysiology of an organism. Recently, proteomic signatures composed of low molecular weight molecules have been identified using mass spectrometry combined with bioinformatic algorithms. Attempts to sequence and identify the molecules that underpin the fingerprints are currently underway.

Pegylated, steptavidin-conjugated quantum dots are effective detection elements for reverse-phase protein microarrays.

Protein microarray technologies provide a means of investigating the proteomic content of clinical biopsy specimens in order to determine the relative activity of key nodes within cellular signaling pathways. A particular kind of protein microarray, the reverse-phase microarray, is being evaluated in clinical trials because of its potential to utilize limited amounts of cellular material obtained through biopsy. Using this approach, cellular lysates are arrayed in dilution curves on nitrocellulose substrates for subsequent probing with antibodies.

Opportunities for nanotechnology-based innovation in tissue proteomics.

Within this review we discuss two methodologies used in tissue proteomics, namely mass-spectrometry (MS)-based protein pattern diagnostics and protein microarrays. Further, we describe current goals within the field of tissue proteomics and suggest points of departure for designing nanotechnology-based tools that will enhance the role of molecularly based diagnostics and therapeutics development in clinical medicine.

Characterization of the cellular uptake and metabolic conversion of acetylated N-acetylmannosamine (ManNAc) analogues to sialic acids.

"Sialic acid engineering" refers to the strategy where cell surface carbohydrates are modified by the biosynthetic incorporation of metabolic intermediates, such as non-natural N-acetylmannosamine (ManNAc) analogues, into cellular glycoconjugates. While this technology has promising research, biomedical, and biotechnological applications due to its ability to endow the cell surface with novel physical and chemical properties, its adoption on a large scale is hindered by the inefficient metabolic utilization of ManNAc analogues. We address this limitation by proposing the use of acetylated ManNAc analogues for sialic acid engineering applications.
