The present study evaluated the impacts of fibre-degrading enzymes on the profiles of non-starch polysaccharides(NSP)and oligosaccharides(OS)in the ileum of broiler chickens offered wheat-or maize-based diets under subclinical necrotic enteritis(NE)challenge.A 224 factorial arrangement of treatments was *** were the following:NE challenge,no or yes;diet type,wheat-or maizebased;and supplemental enzymes,control(no enzyme),family 10 xylanase(XYN10),family 11 xylanase(XYN11)or b-mannanase(MAN).Birds in the challenged group were inoculated with Eimeria on d 9 and Clostridium perfringens on d 14 and 15.A 3-way interaction(P=0.047)occurred on overall(d 0 to 16)weight *** NE was present,all the supplemental enzymes increased weight gain in birds fed the wheat-based diet;whereas in those fed the maize-based diet supplemental XYN10 and XYN11 decreased weight *** NE was absent,birds fed the wheat-based diet supplemented with XYN10 or MAN presented increased weight gain compared to non-supplemented birds,but no improvements with enzyme addition were observed in birds fed the maize-based diet.A 3-way interaction(P=0.002)was observed on insoluble NSP level in the *** NE was absent,all the supplemental enzymes reduced the ileal level of insoluble NSP,regardless of diet *** the challenged birds,supplementing XYN10 and MAN reduced insoluble NSP level in the ileum,but only in birds fed the wheat-based *** soluble NSP level was reduced by supplemental XYN11 and MAN,but only in birds fed the wheatbased diet,resulting in a 2-way diet typeenzyme interaction(P<0.001).Ileal OS arabinose(P=0.030)level was highest in birds offered the wheat-based diet supplemented with ***,supplementation of NSP-degrading enzymes to the wheat-based diet enhanced bird performance regardless of NE challenge,with XYN11 significantly increasing oligosaccharide ***,enzyme addition did not improve growth performance in birds fed maize-based diet

The present study investigated whether supplementing fibre-degrading enzymes can ameliorate the severity of subclinical necrotic enteritis(NE)in broiler chickens offered wheat-or maize-based diets.A total of 1,544 mixed-sex broiler chickens were assigned to 16 experimental treatments as a 2×2×4 factorial arrangement of *** factors were the following:NE challenge,yes or no;diet type,wheat-or maize-based;and enzyme supplementation,control(no enzyme),family 10 xylanase(XYN10),family 11 xylanase(XYN11)or b-mannanase(MAN).Each treatment was replicated 6 times,with 16 birds per replicate pen.A three-way challenge×diet type×enzyme interaction occurred for body weight at 21 d of age(P=0.025)and overall feed conversion ratio(P=0.001).In the non-challenged birds fed the wheat-based diet,supplementing MAN increased d 21 body weight compared to the *** challenged birds fed the maize-based diet,supplemental XYN11 impeded body weight and overall FCR compared to the *** offered the maize-based diet presented heavier relative gizzard weights at both 16 and 21 d of age(P<0.001)and reduced liveability(P=0.046)compared to those fed the wheatbased *** supplementation reduced ileal and jejunal digesta viscosity at 16 d of age only in birds fed the wheat-based diet(P<0.001).XYN11 increased ileal digesta viscosity in birds fed the maizebased diet,and MAN reduced it in birds fed the wheat-based diet at 21 d of age(P=0.030).Supplementing XYN11 improved ileal soluble non-starch polysaccharides(NSP)digestibility in birds fed the wheat-based diet compared to non-supplemented birds(P<0.001).Birds fed the wheat-based diet displayed a higher abundance of Bifidobacterium,Lactobacillus and Enterobacteriaceae and butyric acid in the caeca at 16 d of age compared to birds fed the maize-based diet(P<0.05).In conclusion,supplemental XYN11 exacerbated the negative impact of NE on growth performance in birds fed the maizebased *** wheat-based diets with

OBJECTIVES: Skin characteristics change depending on the external environment such as UV, temperature and humidity. But the research how to affect the regional climate, age and seasonal variation on the skin conditions was not well studied. Therefore, we investigated the seasonal variation in the skin by comparing Beijing women and Guangzhou women by age groups. METHODS: 440 healthy Chinese women participated in this study. The skin hydration, sebum secretion, TEWL and skin pH were measured on the cheek front. All the parameters were analyzed in terms of the age, season and region. RESULTS: The skin hydration in Beijing was lower than that in Guangzhou and significantly decreased during winter than summer. The sebum secretion in their 20s and 30s was significantly high in summer in both regions, and this phenomenon was more remarkable in Guangzhou (p CONCLUSIONS: Skin hydration and barrier function decreased more during a cold, dry winter than summer. The barrier dysfunctions such as an increase in TEWL and pH occurred more commonly in old age groups. The greater the differences between summer and winter climates, the greater damage to skin barrier and skin hydration. The sebum secretion was more affected by hot, humid summers. Further, the aged skin was influenced by seasonal variation except for sebum secretion.

We formulated new skin care cosmetics with lamella structure in which high amount of pseudo-ceramides were incorporated. Consistency of this lamellar gel creams were checked for 1 month on various temperatures and for 1 year on RT. Generally, multi-lamellar emulsion shows typical Maltese cross on polarized microscope, but Maltese cross was not found in case of these creams; Multi-lamellar structure of the creams could be identifed by small-angle X-ray scattering （SAXS）. To evaluate skin barrier recovery function, we applied one of this creams and a vehicle cream to forearm skin which is tape-stripped to remove barrier layer to see if they infuence mass of molecules related to barrier function. 96 h after application, we found that this lamellar gel cream promoted synthesis of ceramides, amino acids and NMFs, thereby enhanced barrier recovery function.

目的:观察含有灰树花子实体及绿茶提取物眼霜的抗衰老效果。方法:采用无创性仪器检测以及图像分析的方法,对23例受试者持续6周外用眼霜的效果进行分析。无创性检测的主要功效参数为眼部细纹(鱼尾纹)和皮肤弹力。采用VISIA-CR图像分析的方法进行眼部肤色评价。结果:使用测试眼霜6周后,眼部鱼尾纹各参数较0周基准值相比均有不同程度降低,但结果无显著性差异(P>0.05)。左、右双眼皮肤弹力平均值较0周的0.66/0.64上升到6周的0.76/0.74,且差异有统计学意义(P<0.05)。眼部肤色的亮度和均匀度较0周均有明显改善,改善幅度分别为0.54%和5.63%,且差异有统计学意义(P<0.05)。结论:含灰树花子实体及绿茶提取物眼霜可以有效提高眼部皮肤亮度和均匀度,增强皮肤弹力,且具有较高安全性。
