Carnosine (Carn) occurs in high concentrations muscle where it contributes to H+ buffering. Carn (ß-AlaHis dipeptide) can be increased 60% or more by supplementation with ß-alanine (ß-Ala), which is rate limiting for synthesis muscle. ß-Ala obtained from meat ingestion the liver. PURPOSE To compare content of V Lateralis vegetarians and omnivores. METHOD A biopsy was 6 lacto-ovo- ovo-vegetarians 2 pescetarians resident UK analysed Carn. Values were compared those 4 groups students (UK,...

아라비녹실레인은 발효 유색미 겨에서 추출한 수용성 식이섬유로서 항산화 기능 면역증진 및 염증억제 효과 등이 밝혀져 있다. 이 연구에서는 천연식품소재로서 생체기능성 효과가 우수한 것으로 알려진 아라비녹실레인의 면역기능 효과를 평가하였다. 이를 위해 흰 쥐를 대상으로 4주간 시료 투여와 운동트레이닝의 함께 비교하였으며 lipopolysaccharide를 이용하여 염증반응을 유발하였다. 연구 결과에서, 아라비녹실레인 투여에 의한 염증 억제효과를 확인할 수 있었다. 염증반응의 대표적인 지표인 tumor necrosis factor-<TEX>${\alpha}$</TEX> (TNF-<TEX>${\alpha}$</TEX>)와 interleukin-6 (IL-6)의 활성은 투여 집단에서 가장 낮게 나타났으며 운동트레이닝 집단이 높게 나타났다. 특히 아라비녹실레인을 섭취하면서 운동을 실시한 IL-6와 TNF-<TEX>${\alpha}$</TEX>의 활성이 운동트레이닝만을 집단에 비해 감소된...

Carnosine (Carn) occurs in high concentrations muscle where it contributes to H+ buffering. Highest levels occur chronically trained athletes. Carn (ß-AlaHis dipeptide) can also be increased 60% or more by supplementation with ß-alanine (ß-Ala), which is rate limiting for synthesis muscle. The aim of this study was investigate the effect training without ß-Ala on during a 10 week program strength training. Male Vietnamese physical education students (n=26) aged 20–26 yrs, normal body mass...

PURPOSE: Previous studies have reported that low-load high-repetition (LLHR) resistance exercise can induce muscle hypertrophy to a similar extent as high-load low-repetition (HLLR). However, it is unclear which mechanical stress, such intensity, contraction number, and/or total work volume and molecular mechanisms underpin the greater relative after LLHR exercise.METHODS: Sprague-Dawley rats (12 weeks, N=35) were randomly allocated into control (Con, n=7), (LLLR, medium-repetition (LLMR,...

Paper mills are currently pressed to reduce costs because of lack resources and rising oil prices. Accordingly, paper increasing the quantity low-priced pulp using a ratio with relatively low whiteness by decreasing use high-priced, high-quality pulp. To solve problem deteriorated whiteness, regularly fluorescent whitening agent. In addition, increase resource recycling environmental problems, interest is growing in recycled paper, which partially or completely contains pulp.BR this study,...
