Several areas of evidence suggest that multifocality is not necessarily a limiting factor for tissue preservation.
The pH level of Makgeolli, as an alcoholic drink, is a significant factor for its preservation and fermentation process.
In agreement with the published literature, main prognostic factors for hearing preservation were size of the extrameatal portion and stage of the tumor, preoperative hearing level, and possibility to employ intraoperative BAEP monitoring.
Various forms of application (i.v., middle ear, topical) and different medications (triamcinolone, dexamethasone, prednisolone) are used and thought to be important factors for the preservation of residual hearing [ 13, 14].
Besides advances in organ preservation, the presence of steatosis remains a limiting factor for the suitable preservation of liver grafts, as steatotic livers are particularly vulnerable to hepatic ischemia reperfusion injury (IRI) [ 2].
The understanding of their behaviour when exposed to weathering factors is crucial for preservation, replacement and restoration intervention.
Moreover, as shown in Fig. 6, no readily apparent trend indicates that the preservation potential of the tsunami deposit along each transect was different, suggesting that the topography at each transect is not an important factor for the sediment preservation at our studied sites.
Keeping the pH low (around 4.0) by lactic acid in silage is an important factor for long-term preservation [ 5].
Our study found that the patients who developed hearing degradation were characterized as having significantly larger tumor volumes than those of patients with preserved hearing, which was in agreement with the study by Kano et al., [ 25] revealing that a tumor volume <0.75 cm was a significant prognostic factor for serviceable hearing preservation.
The maintenance of the periprosthetic bone probably reflects the mechanical characteristics of the femoral stem, confirming the idea that implant-related factors are most critical for preservation of bone stock (van Rietbergen and Huiskes 2001).
