Mucopolysaccharidosis (MPS) is a disorder which is caused by the defect of the lysosomal enzyme that is essentially needed for resolution of glycosaminoglycans (GAGs). Metabolite of GAGs will accumulate in the lysosome of cells and will result in the dysfunction of cells, tissues, and organs. Eventually, patients will manifest both mental retardation and physical disorders. In worst cases, mucopolysaccharidosis can cause premature death. The current clinical types have been classified as MPS from type I to type IX according to the defect of certain enzyme. The dental complications have been reported as delay of eruption, enamel hypoplasia, microdontia, malocclusion, condylar defects, gingival hyperplasia and dentigerous cystlike follicle. This clinical report presents the case of a boy with MPS type II, Hunter Syndrome which has various dental complications.

This study examined the effects of pre-slaughter fasting, chasing stress and chiller ageing on objective meat quality, and their relations to the proteome profile of longissimus muscle using 20 male Korean native black pigs. Treatments were composed of two levels of pre-slaughter feed withdrawal, two levels of pre-slaughter stress and four chiller ageing times. A 15 min chasing stress immediately prior to slaughter significantly (p<0.05) decreased detectable levels of $\mu$-calpain activity during rigor development and chiller ageing, but did not have any direct effect on objective meat quality. On the other hand, pigs fed until the morning of slaughter resulted in significantly (p<0.05) higher hunter L* value and cooking loss than those which received an 18 h feed withdrawal prior to slaughter. Cooking loss and hunter L* value were constant during 7 d of chiller ageing, followed by significant increases at 14 d. The fed animals showed a significantly (p<0.05) higher hunter a* value at both 3 and 7 d, while the other group maintained a stable redness for 7 d. WB-shear force was not affected by the pre-slaughter treatments, but had significant (p<0.05) linear reduction from 1 to 7 d. A gelbased proteome analysis was performed on selected animals for low and high hunter L* values at 1 d. Ten and five spots had greater than two-fold spot densities for the low and high hunter L* groups, respectively. The ten spots included chain A, deoxyribounclease I complex with actin, heat shock protein 27 kDa, a protein similar to cardiac $Ca^{2+}$ release channel, and myosin heavy chain, while the five spots included chain A aldehyde dehydrogenase, glycerol-3 phosphate dehydrogenase, and hemoglobin alpha chain. In general, feeding until the morning of slaughter resulted in more desirable meat color, but appeared to reduce palatability due to increased cooking loss. Proteome analysis demonstrated that various proteins were concomitantly involved in the determination of final meat color. The most noticeable observation in the current study was that various isoforms for a particular protein differed in degradation and/or expression rate depending on meat quality.

Quality evaluations of seasoning chicken wing treated with pine needles during storage of 6 days at $4^{\circ}C$ were assessed. Seasoning chicken containing 0.5-1.3% (w/w) pine needle during storage at $4^{\circ}C$ was allowed to the growth of Staphylococcus aureus. pH values of seasoning chicken containing pine needles after 6 days of storage were not significantly different (p>0.05) than those of the controls. The rate of drip loss on seasoning chicken containing pine needles after 24 hr of storage was significantly different (p<0.05) than that of the controls. Sensory scores of seasoning chicken containing 0.8-1.3% pine needles for odor and flavor were in the "liked more" to typical category during storage of 6 days at $4^{\circ}C$. For odor and flavor scores, seasoning chicken containing 1.0-1.3% pine needles compared to the controls and other treatments increased during storage days due to fresh odor of pine needles. Seasoning chicken containing 0.5-1.3% pine needles after 6 days of storage were no significantly different levels (p>0.05) of Hunter color $L^*$ values compared to controls. Hunter color $a^*$ and $b^*$ values of seasoning chicken containing 0.5-1.3% pine needles after 6 days of storage were significantly different (p<0.05) than those of the controls.

This study was conducted to evaluate the quality attributes of cooked hams made with four hind leg muscles (Biceps femoris, Semimembranosus, Rectus femoris, Gluteus medius) and Longissimus dorsi. Muscles were prepared from three market-weighted crossbreeds ($L{\times}Y{\times}D$) and the pH, proximate chemical composition, color, texture attributes, and sensory properties of cooked pork muscle hams were evaluated. In the raw state, no significant differences in pH were found among the five muscle hams. However, Rectus femoris ham had the highest pH, while Longissimus dorsi ham had the lowest pH (p<0.05). All muscle hams had similar moisture, fat, and ash contents. The protein content (%) was highest in Longissimus dorsi ham (p<0.05). The Hunter L value was highest for Longissimus dorsi ham while Rectus femoris and Gluteus medius hams had the lowest Hunter L values (p<0.05). The Hunter a values were similar in Rectus femoris, Biceps femoris, and Gluteus medius hams, and lowest for Longissimus dorsi ham (p<0.05). Texture attributes were not significantly different among the five muscle hams (p>0.05). The results of sensory evaluation showed that Semimembranosus hams had the highest flavor score, but there were no significant differences among five muscle hams with regard to color, taste, and texture (p>0.05).

This study was conducted to measure tea surface colors using the visible bands ($400{\sim}700$ nm) with near-infrared spectroscopy (NIRS). The surface colors of 117 tea products were measured with a colorimeter. The $a^*/b^*$ (CIE color scale) or a/b (Hunter color scale) ratios in different tea products accounted for about 99.7% of the variation in fermentation degree (FD), indicating that the $a^*/b^*$ (a/b) ratio is a very useful trait for assessing fermentation degree. Also tea powders were scanned in the visible bands used with NIRS. Calibration equations for surface colors and fermentation degree were developed using the regression method of modified partial least-squares (MPLS) with internal cross validation. The equations had low SECV (standard errors of cross-validation), and high $R^2$ (coefficient of determination in calibration) values with $0.779{\sim}0.999$, indicating that the whole bands ($400{\sim}2500\;nm$) with NIRS could be used to rapidly measure traits related to surface color, fermentation degree and other chemical components in tea products with high precision and ease at a time.
