This study develops several chemical and physical methods to evaluate the quality of a traditional Chinese formulation, Jia-Wei-Xiao-Yao-San. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) coupled with electrospray ionization was used to measure the herbal biomarkers of saikosaponin A, saikosaponin D, ferulic acid, and paeoniflorin from this herbal formula. A scanning electron micros...

Spider dragline silk is a natural fiber that has excellent tensile properties; however, it is difficult to produce artificially as a long, strong fiber. Here, the spider (Araneus ventricosus) dragline protein gene was cloned and a transgenic silkworm was generated, that expressed the fusion protein of the fibroin heavy chain and spider dragline protein in cocoon silk. The spider silk protein co...

The effect of inclusion of garlic essential oil (EO) at 33, 66 and 100 µg mL(-1), raw garlic (GAR) at 5, 10 and 15 mg mL(-1) and monensin (MON) at 7.5 µg mL(-1) of incubation medium on organic matter digestibility (OMD) was studied with in vitro gas production, ANKOM daisy(II) and conventional in vitro (IVOMD) methods. The material was incubated with sheep ruminal fluid and the experimental des...

The impact was studied of buffer pH (5.8, 6.2, and 6.8) on in vitro digestion kinetics of NDF from alfalfa hay, bromegrass hay, corn silage, and alfalfa and bromegrass hays with raw corn starch added to approximate a ration containing 30% NDF. Ash-free NDF was determined at 0, 6, 12, 18, 24, 30, 36, 48, 72, and 96 h of fermentation. Kinetic parameters were estimated by nonlinear regression usin...

The purpose of this study was to increase the nutritional value two raw materials (soybean straw and ryegrass hay), in order propose use as feed for ruminants. Different technologies were used develop animal feed: addition proteins, Spirulina platensis biomass, solid state fermentation by Aspergillus niger, encapsulation microalgae biomass (capsules with xanthan gum chitosan), well control test...

Textile chitosan fiber scaffolds were developed and tested in terms of biocompatibility for human bone marrow stromal cells (hBMSCs). A part of the scaffolds was further modified by coating with fibrillar collagen type I in order to biologize the surface. hBMSCs of two donors were used for cell culture experiments in vitro. Confocal laser scanning microscopy (CLSM) as well as scanning electron ...

Cellulose nanocrystals (CNCs) were isolated from corn stalk using sulfuric acid hydrolysis, and their morphology, chemical structure, and thermal stability properties were characterized. The CNCs had an average length of 120.2 ± 61.3 nm and diameter of 6.4 ± 3.1 nm (L/D = 18.7). The degree of crystallinity of the CNCs increased to 69.20% from the 33.20% crystallinity of raw corn stalk fiber, wh...

Context modelling is one of the stages conducted during the context life cycle. It has the aim of giving meaning and structure to the collected context’s raw data. Although there are different context models proposed in the literature, we have identified some gaps that are not fully covered, particularly related to the reusability of the models themselves and the lack of consolidated and standa...

We consider a brane N = I × S0, where S0 is an ndimensional space form, not necessarily compact, in a SchwarzschildAdS(n+2) bulk N and prove that, for specific negative pressures on the brane, the brane is an ARW space. By reflecting N and N to N̂ and N̂ , the joint branes N ∪ N̂ can be naturally embedded as a C∞hypersurface in R2 ×S0, if n is odd and if ω = − n−1 2 is chosen, a value that corresp...

PURPOSE The low masticatory efficiency of denture prostheses impairs the ability of wearers to consume high-fiber foods. Hence, artificial teeth with high masticatory efficiency are required. This study aimed to establish an occlusal surface design for posterior artificial teeth in denture prostheses that is compatible with the existing artificial teeth arrangement and that has high masticatory...
