The use of craniofacial implants to assist in retaining auricular prostheses often requires complex laboratory procedures, involving production of an accurate casting, fitting of a precious alloy bar, and the use of clips. A simplified method for the retention of an auricular prosthesis with a composite bar and magnets is described in this article.

BACKGROUND Rhinoplasty and septal surgery often require the use of cartilage grafts. Autologous cartilage may be thin or deviated, and the use of an absorbable scaffold material to support the reimplanted cartilage during healing can improve technique and outcomes. OBJECTIVE To describe the use of a polydioxanone plate not only as a template in extracorporeal septoplasty but also for various ...

The aim of this work was to make biodegradable plastics from renewable resources. Paper-based biodegradable plastics were produced via a sol-gel process by using zinc chloride solution. The optimum conditions were a zinc chloride concentration of 65%, reaction temperature of 70 °C, reaction time of 5 s, aging time of 3 h, and glycerol concentration of 10%. Fourier transform infrared spectroscop...

Fungi native to agricultural soils that colonized commercially available biodegradable mulch (BDM) films were isolated and assessed for potential to degrade plastics. Typically, when formulations of plastics are known and a source of the feedstock is available, powdered plastic can be suspended in agar-based media and degradation determined by visualization of clearing zones. However, this appr...

Lack of degradability and the closing of landfill sites as well as growing water and land pollution problems have led to concern about plastics. With the excessive use of plastics and increasing pressure being placed on capacities available for plastic waste disposal, the need for biodegradable plastics and biodegradation of plastic wastes has assumed increasing importance in the last few years...

The possible origin of luminescent properties of biodegradable photoluminescent polyesters (BPLPs) has been revealed by isolation and identification of luminescent agent from the hydrolyzate of BPLP. Elemental analysis, ESI-MS, (1)H, (13)C, 2D HSQC and COSY NMR spectra confirmed the chemical structure as 5-oxo-2,3-dihydro-5H-[1,3]thiazolo[3,2-a]pyridine-3,7-dicarboxylic acid (TPA).

Management of clavicle fractures continues to evolve. Indications for operative management seem to be expanding, particularly in athletic youth. Surgical intervention has potential complications, many associated with use of metal implants. To my knowledge, this case report is the first to describe use of a biodegradable implant. The subcutaneous position of the clavicle makes it ideal for fixat...

Even so, extensive research has been carried out on potential eco-toxic effects of particulate and extensively degraded oxo-biodegradable plastics when mixed with soil. Tests included seed germination and plant growth rates, compared with the same soil without degraded plastics [3,4], the effects on macro-organisms (worms, daphnia, etc.) in the soil [4] and on the accumulation of transition met...

The biodegradability of different plastic material was investigated under aerobic conditions. The samples were placed in the compost pile and were checked over 15 weeks. After the expiration of the experimental period it was found that the samples with the additive (samples 1, 2, and 3) had not decomposed, their color had not changed, and that no degradation or physical changes had occurred. SE...
