Platelet-rich plasma containing various growth factors can promote nerve regeneration. An inside-out vein graft can substitute nerve autograft to repair short nerve defects. It is hypothesized that an inside-out vein graft filled with platelet-rich plasma shows better effects in the repair of short sciatic nerve defects. In this study, an inside-out vein autograft filled with platelet-rich plasma was used to bridge a 10 mm-long sciatic nerve defect in rats. The sciatic nerve function of rats with an inside-out vein autograft filled with platelet-rich plasma was better improved than that of rats with a simple inside-out vein autograft. At 6 and 8 weeks, the sciatic nerve function of rats with an inside-out vein autograft filled with platelet-rich plasma was better than that of rats undergoing nerve autografting. Compared with the sciatic nerve repaired with a simple inside-out vein autograft, the number of myelinated axons was higher, axon diameter and myelin sheath were greater in the sciatic nerve repaired with an inside-out vein autograft filled with plateletrich plasma and they were similar to those in the sciatic nerve repaired with nerve autograft. These findings suggest that an inside-out vein graft filled with platelet-rich plasma can substitute nerve autograft to repair short sciatic nerve defects.

Sodium chloride is one of the most widely used additives in meat curing. However， cured meat products contribute to a portion of the total sodium dietary intake. Consumers and researchers’ concern about excessive sodium intake has prompted the food industry to consider ways to reduce salt content of cured meat products. The aim of this review is to provide a broad but comprehensive understanding of salt reduction strategies for cured meat products. The impact and limitations of each approach were discussed. Green technologies treatments， such as ultrasonic technology， high-pressure processing， seem to be potential to ensure microbiological safety in low-sodium cured meat products. However， these novel technologies can cause protein and fat oxidization in meat products. A combination of multiple treatments could give the desired effect. In addition， different parameter conditions need to be set according to the specific meat to achieve better salt reduction effect.

The carbon dioxide （CO2） concentrations and fluxes measured at a height of 17.5 m above the ground by a sonic anemometer and an open-path gas analyzer at an urban residential site in Seoul, Korea from February 2011 to January 2012 were analyzed. The annual mean CO2 concentration was found to be 750 mg m-3, with a maximum monthly mean concentration of 827 mg m-3 in January and a minimum value of 679 mg m-3 in August. Meanwhile, the annual mean CO2 flux was found to be 0.45 mg m-2 s-1, with a maximum monthly mean flux of 0.91 mg m-2 s-1 in January and a minimum value of 0.19 mg m-2 s-1 in June. The hourly mean CO2 concentration was found to show a significant diurnal variation; a maximum at 0700-0900 LST and a minimum at 1400-1600 LST, with a large diurnal range in winter and a small one in summer, mainly caused by diurnal changes in mixing height, CO2 flux, and surface complexity. The hourly mean CO2 flux was also found to show a significant diurnal variation, but it showed two maxima at 0700-0900 LST and 2100-2400 LST, and two minima at 1100-1500 LST and 0300-0500 LST, mainly caused by a diurnal pattern in CO2 emissions and sinks from road traffic, domestic heating and cooking by liquefied natural gas use, and the different horizontal distribution of CO2 sources and sinks near the site. Differential advection with respect to wind direction was also found to be a cause of diurnal variations in both the CO2 concentration and flux.

AIM： To clarify whether insulin resistance and metabolic syndrome are risk factors for erosive esophagitis.METHODS： A case-control study was performed using the database of the Kangbuk Samsung Hospital Medical Screening Center.RESULTS： A total of 1679 cases of erosive esophagitis and 3358 randomly selected controls were included. Metabolic syndrome was diagnosed in 21% of the cases and 12% of the controls （P 〈 0.001）. Multiple logistic regressions confirmed the association between erosive esophagitis and metabolic syndrome （Odds ratio, 1.25; 95% CI, 1.04-1.49）. Among the components of metabolic syndrome, increased waist circumference, elevated serum triglyceride levels and hypertension were significant risk factors for erosive esophagitis （all P 〈 0.01）. Furthermore, increased insulin resistance （Odds ratio, 0.91; 95% CI, 0.85-0.98） and fatty liver, as diagnosed by ultrasonography （odds ratio, 1.39; 95% CI, 1.20-1.60）, were also related to erosive esophagitis even afl：er adjustment for a series of confounding factors.CONCLUSION： Metabolic syndrome and increased insulin resistance are associated with an increased risk of developing erosive esophagitis.

A new species of the probable calcareous alga Amsassia, A. koreanensis, is recognized from the Duwibong Formation （Middle Ordovician, Darriwilian） of the Taebaeksan Basin in mid-eastern Korea. This is the first report of the genus from the Korean Peninsula, expanding its geographical range to the eastern Sino-Korean Block. The new species also occurs in the Xiazhen Formation （Upper Ordovician, Katian） at Zhuzhai in the South China Block. Amsassia koreanensis is the smallest species of this modular genus, having a maximum module diameter of 0.28 ram. Module increase is by bipartite, tripartite and quadripartite types of longitudinal axial fission, but unlike other species of the genus, quadripartite fission is common. The types of fission are comparable to those in some Tetradiida （now Prismostylales, florideophycean rhodophyte algae）, although the processes of fission are different. The distribution of A. koreanensis further strengthens the biogeographical connection between the Sino-Korean and South China blocks, suggesting that these two paleocontinents were located closer together during the Middle to Late Ordovician than previously speculated.

The latest publications regarding the development of technology to control inclusion compositions focusing on MgO?Al2O3 spinel inclusions were summarized in this review article. The problems caused by spinel inclusions, which affect practice as well as products were shown. The formation mechanism of MgO?Al2O3 spinel inclusions is secondly explained thermodynamically from the view points of chemistries of molten steels and slag compositions. Furthermore, crystallization behaviour of spinel was introduced. Countermeasures conducted in practices and laboratories were shown along with some problems still left that should be solved in the future.
