A Pilot Study to Determine the Impact of Adipose Tissue Attachment to Polypropylene Fibers In Hernia Mesh.

Introduction: Prior publications have demonstrated chemical and physical alteration of hernia mesh analyzed after explantation from the body. The specific alteration documented is oxidative degradation of polypropylene mesh fibers. An animal study recently published has demonstrated that adipose tissue attachment is present instead of reparative fibrous tissue infiltration in an average of 10.

A comparison of proteomic, genomic, and osteological methods of archaeological sex estimation.

Sex estimation of skeletons is fundamental to many archaeological studies. Currently, three approaches are available to estimate sex-osteology, genomics, or proteomics, but little is known about the relative reliability of these methods in applied settings. We present matching osteological, shotgun-genomic, and proteomic data to estimate the sex of 55 individuals, each with an independent radiocarbon date between 2,440 and 100 cal BP, from two ancestral Ohlone sites in Central California.

A novel crosslinker-free technique toward the fabrication of collagen microspheres.

Injectable collagen microspheres (CMs) have the potential to be an excellent tool to deliver various modulatory agents or to be used as a cellular transporter. A drawback has been the difficulty in producing reliable and spherical CMs. A crosslinker-free method to fabricate CMs was developed using liquid collagen (LC) in a water-in-oil emulsion process with varying concentrations of surfactant span-80.
