OBJECTIVE To test the integrity of knots tied with expired suture and non-expired suture, using 5 different suture materials. STUDY DESIGN Knots were tied using expired and non-expired chromic catgut, polyglactin 910, polydioxanone, silk, or coated polyester. Expired sutures were a mean of 10.5 years past the date of expiration stamped on the packaging. Suture packaging was inspected for any ...

near-surface environment. Also, many of the complicating effects found in the near-surface environment will Approaches for estimating liquid flux in the shallow (0–2 m) vadose be damped or eliminated with increasing depth. For zone are hindered by the high degree of spatial and temporal variability present near the land surface. It is hypothesized that high-frequency these reasons, flux measure...

Abstract The foam properties of different surfactants were evaluated by the stirring method. synergistic stabilizing effect was formed combination lauryl glucoside and hydrophilic nanoparticles, but result feeble. blend Janus nanoparticles significantly improves stability, two have a strong on stability. compound system has specific temperature resistance. Kruss dynamic surface tensiometer dila...

The knowledge of the continuous evolution soil hydraulic characteristics is required for several environmental geotechnical applications such as capillary barrier systems and river bank slope stability analysis. Such data are obtained in field by embedding suction sensors slopes equilibrium time other limitations establishing not available compacted soils. Thus influence initial moisture conten...

BACKGROUND The use of alloplastic meshes has been historically contra-indicated in patients with infection. AIM To evaluate the use of polypropylene meshes in the treatment of abdominal wall defects in rats with peritonitis. METHODS Twenty Wistar female rats were divided into two groups: induction of peritonitis (test group) and without peritonitis (control group). An abdominal wall defect ...

Young shoots of Rubus species have been used for healing of wounds, infected insect bites and pimples in folk medicine for ages. In order to evaluate the wound healing activity of Rubus sanctus, four different extracts were prepared from the whole aerial parts of the plant by using n-hexane, chloroform, ethyl acetate and methanol, respectively. Incision wound healing model by using tensiometer ...
