A retained intrahepatic bullet in the Bermuda triangle: A case report of surgical extraction.

Introduction And Importance: The management of retained gunshot injury in the liver is not properly discussed in the literature.

Case Presentation: We describe a rare case of intrahepatic retained foreign body (bullet). Our patient is a 39-year old Yemeni soldier, who was exposed to firearm injury 10 months previously.

Platelet-derived growth factor BB treated osteoprogenitors inhibit bone regeneration.

The study evaluates the ability of osteoprogenitors treated with platelet-derived growth factor BB (PDGF-BB) delivered on vinyl styrene microbeads (VSM) to regenerate rat calvarial critical-size defects (CSDs). Fetal rat calvarial cells were cultured and tested for their ability to attach to VSM using scanning electron microscopy. Twenty-five rats were equally divided into 5 groups; a negative control (GPI), vinyl styrene microbeads (GPII), PDGF-BB (GPIII), VSM plus osteoblastic progenitors (GPIV), and VSM plus PDGF-BB treated osteoblastic progenitors (GPV).

Osteoconductive effects of vinyl styrene microbeads in rat calvarial defects.

Purpose: The aim of the present study was to evaluate the use of the nonresorbable vinyl styrene microbeads (VSM) alloplast as a delivery vehicle for platelet-derived growth factor (PDGF-BB) in rat calvarial critical size defects.

Materials And Methods: Seventy-three Long-Evans male rats were divided into 4 groups; a negative control, vinyl styrene microbeads (VSM), PDGF-BB, and VSM plus PDGF-BB. Critical size calvarial defects were carried out and isolated with membranes sandwiching the defects with their fillers.
