Healing sequence

Polylactic Acid. Polylactic acid (PLA) was introduced in 1966 for degradable surgical implants. Hydrolysis yields lactic acid, a normal intermediate of carbohydrate metaboHsm (23). PolyglycoHc acid sutures have a predictable degradation rate which coincides with the healing sequence of natural tissues. 

There are several ways to represent the findings of histopathologic analysis. One approach which clearly demonstrates the healing sequence of events as studied through histopathologic analysis is the series of schematic illustrations prepared by Marois et al. (Figure 8.3). ... 

Table 36.2 identifies the events in the inflammatory responses and indicates the predominant cell type found in these responses. These characteristic ceU types are utilized in histological studies to identify the phase or event in the inflammatory and wound healing sequence of events. 

Q Suggest a reaction sequence whereby furan reacts with diethyl acetylenedicarboxylate to form a compound that can be partially hydrogenated and healed to give ethene and 3.4-bis(ethoxycar-bony )furan. 

Inflamed tissue associated with an oxidative stress as a consequence of a disbalance in the pro-oxidant/antioxidant homeostasis in chronic wounds is thought to drive a deleterious sequence of events that finally results in the non-healing state [29]. Experimental studies showed that wounds of delayed healing type are accompanied... 

Some of Ihese reactions would rely upon a nuclear reactor as a heal source and would not have to await the ctneigenee of a practical, operating fusion reactor. One sequence of reactions, in particular, is of interest ... 

Despite the variety of different sources, sequences and structures, all cationic antimicrobial peptides share some common features small size (12-50 amino acids), positive net charge (+2 to +9), amphiphilic (>30% hydrophobic amino acids) and antimicrobial and/or immunomodulatory activity. Some cationic antimicrobial peptides also show antiviral (14) and/or anticancer activity (15) as well as wound healing properties (16). More than 1000...
