Mixed linkage β-1.3 - 1.4 beta-glucan (beta-glucan, in this paper) is a confirmed beneficial ingredient for the human diet through reduction of cholesterol and the glycemic index. Barley contains the highest beta-glucan content of all the grains, and in this study, a percentage of flour from two high beta glucan lines was, each, added to an array of wheat-based food products to measure how it impacted total dietary fiber. Results showed that beta-glucan content was higher in all the products containing the added high beta-glucan flour, along with increased total dietary fiber content. Protein content in the food products is also increased with the higher protein in the barley flours added. Beta-glucan content in the barley-added products increased to 1.2% - 4.0% versus 0.2% - 0.5% in the pure wheat products, while the dietary fibers increased to 3.5% - 24.4% versus 2.1% - 9.1% in pure wheat product controls. This research provided experimental evidence that using a high beta-glucan barley ingredient in food can increase dietary fiber to benefit health.展开更多

The ...Aegle marmelos, widely known as bael, belongs to the Rutaceae family. It is one of the most inexpensive and appealing fruits, considered to be an essential source of natural antioxidants and bioactive components. The major purpose of the research study was to investigate the nutritional composition and bioactive constituents of bael pulp, as well as to develop new value-added products that maintain the maximum quantity of nutrients. The developed food products were subjected to evaluate sensory attributes according to a nine-point hedonic scale. It was found that the moisture, protein, fat, crude fiber, and total ash content of bael fruit pulp were 61.20%, 2.48%, 0.47%, 3.04%, and 1.29%, respectively. When compared to the catechin standard, the antioxidant activity of such extract indicated good antioxidant capacity, with an IC<sub>50</sub> value of 75.68 μg/ml for methanol extract. Vitamin C content was about 10.21 mg/100g. Besides, total flavonoid and phenolic contents were found as 140 mg of Quercetin Equivalent (QE)/g and 106.65 mg of Gallic Acid Equivalent (GAE)/g, respectively. Results of sensory attributes revealed that there was a significant difference (P ba and bael bar. The overall acceptability of bael murabba (6.7) and bael bar (7.1) is acceptable in quality, but their specific characteristics were found slightly different by the test panelists. These products might be applicable for the treatment of several diseases like atherosclerosis, diabetes, constipation, irritable bowel syndrome, peptic ulcer, tumor, and osteoporosis.展开更多

Nevertheless, poor corrosion resistance hinders their biomedical applications. Besides, it is necessary to endow Mg alloys with bioactive property, which is crucial for temporary bone implants. Here, a self-healing, corrosion resistant and bioactive duplex coating of plasma electrolytic oxidization(PEO)/polydopamine(PDA) is applied on AZ91 substrate using PEO and subsequent electrodeposition process. Moreover, the role of different electrodeposition times(60 s, 120 s) and dopamine concentrations(1 and 1.5 mg/ml) to improve corrosion resistance, bioactivity, biocompatibility and self-healing property and its mechanism are investigated. The results indicate that the PEO coating is efficiently sealed by the PDA, depending on the electrodeposition parameters. Noticeably, electrodeposition for 120 s in dopamine concentration of 1 mg/ml(120T-1C) results in the formation of uniform and crack-free PDA coating. Duplex PEO/PDA coatings reveal high bioactivity compared to PEO coating, owing to electrostatic interaction between PDA top-layer and calcium and phosphate ions as well as high hydrophilicity of coatings. In addition, duplex PEO/PDA coatings also show improved and more stable protective performance than the PEO and bare alloy, depending on the PDA deposition parameters. Noticeably, the corrosion current density of the 120T-1C decreases one orders of magnitude compared to PEO. In addition, the presence of a broad passivation region in the anodic polarization branch shows durable self-healing property via Zipper-like mechanism, demonstrating the duplex coating could preserve promising corrosion resistance.Furthermore, the cytocompatibility of duplex coated samples is also confirmed via interaction with MG63 cells. In summary, the PEO/PDA coating with great corrosion protection, self-healing ability, bioactivity and biocompatibility could be a promising candidate for degradable magnesium-based implants.展开更多

文摘OBJECTIVE: To study the effects of the drying processing in terms operational parameters on the bioactive constituents of six Yuanzhi(Radix Palygalae)samples across China.METHODS: Six Yuanzhi(Radix Palygalae) samples were investigated using thermogravimetry analysis. The heating courses were set in two ways: thetemperature-programmed process from room temperature to 150℃,and the constant-temperature course at 50℃, 70℃ and 90℃.RESULTS: The peak temperature of six Yuanzhi(Radix Palygalae) samples ranged from 78℃ to 88℃.The mass loss rate ofYuanzhi(Radix Palygalae) alcohol-soluble extract was significantly increased when heated at 90℃. Four types of bioactive ingredients were detected in volatile oils of Yuanzhi(Radix Palygalae) sample from Shanxi province by Gas Chromatography-mass spectrometry analysis. Fourier Transform Infrared Spectroscopy results showed that the drying temperature exerted a great influence on types and amount of ingredients of Yuanzhi(Radix Palygalae). The kinetic study showed that the constant-temperature drying process ofYuanzhi Radix Palygalae) samples could be well described by the Page Model, especially for the drying process at 50℃, in which R2and SD values were more than 0.98 and less than 0.04, respectively. The drying constant k of three Yuanzhi(Radix Palygalae) samples from Shanxi, Gansu and Shaanxi provinces in China was corresponding to the Arrhenius equation, and their activation energies were28.07, 25.38 and 21.48 kJ/mol, respectively.CONCLUSION: The drying process of Yuanzhi(Radix Palygalae) was very important for bioactive ingredients improvement in Yuanzhi(Radix Palygalae). Temperature was a thermodynamic property significantly affecting the process.
文摘Aegle marmelos, widely known as bael, belongs to the Rutaceae family. It is one of the most inexpensive and appealing fruits, considered to be an essential source of natural antioxidants and bioactive components. The major purpose of the research study was to investigate the nutritional composition and bioactive constituents of bael pulp, as well as to develop new value-added products that maintain the maximum quantity of nutrients. The developed food products were subjected to evaluate sensory attributes according to a nine-point hedonic scale. It was found that the moisture, protein, fat, crude fiber, and total ash content of bael fruit pulp were 61.20%, 2.48%, 0.47%, 3.04%, and 1.29%, respectively. When compared to the catechin standard, the antioxidant activity of such extract indicated good antioxidant capacity, with an IC<sub>50</sub> value of 75.68 μg/ml for methanol extract. Vitamin C content was about 10.21 mg/100g. Besides, total flavonoid and phenolic contents were found as 140 mg of Quercetin Equivalent (QE)/g and 106.65 mg of Gallic Acid Equivalent (GAE)/g, respectively. Results of sensory attributes revealed that there was a significant difference (P ba and bael bar. The overall acceptability of bael murabba (6.7) and bael bar (7.1) is acceptable in quality, but their specific characteristics were found slightly different by the test panelists. These products might be applicable for the treatment of several diseases like atherosclerosis, diabetes, constipation, irritable bowel syndrome, peptic ulcer, tumor, and osteoporosis.

One fraction pool was observed to exhibit antimicrobial property resulting in the suppression of cell growth of the test organism ATCC 8739 E. coli. It has a MIC value of 1.5% (w/v, 35°C, 20 hr) and could be useful as a new source of prebiotics or preservatives. The present results further confirm the science and useful application of combinatorial enzyme approach.
文摘Magnesium(Mg) alloys are well-known in biomedical materials owing to their elastic module near to bone, biocompatibility and biodegradation properties. Nevertheless, poor corrosion resistance hinders their biomedical applications. Besides, it is necessary to endow Mg alloys with bioactive property, which is crucial for temporary bone implants. Here, a self-healing, corrosion resistant and bioactive duplex coating of plasma electrolytic oxidization(PEO)/polydopamine(PDA) is applied on AZ91 substrate using PEO and subsequent electrodeposition process. Moreover, the role of different electrodeposition times(60 s, 120 s) and dopamine concentrations(1 and 1.5 mg/ml) to improve corrosion resistance, bioactivity, biocompatibility and self-healing property and its mechanism are investigated. The results indicate that the PEO coating is efficiently sealed by the PDA, depending on the electrodeposition parameters. Noticeably, electrodeposition for 120 s in dopamine concentration of 1 mg/ml(120T-1C) results in the formation of uniform and crack-free PDA coating. Duplex PEO/PDA coatings reveal high bioactivity compared to PEO coating, owing to electrostatic interaction between PDA top-layer and calcium and phosphate ions as well as high hydrophilicity of coatings. In addition, duplex PEO/PDA coatings also show improved and more stable protective performance than the PEO and bare alloy, depending on the PDA deposition parameters. Noticeably, the corrosion current density of the 120T-1C decreases one orders of magnitude compared to PEO. In addition, the presence of a broad passivation region in the anodic polarization branch shows durable self-healing property via Zipper-like mechanism, demonstrating the duplex coating could preserve promising corrosion resistance.Furthermore, the cytocompatibility of duplex coated samples is also confirmed via interaction with MG63 cells. In summary, the PEO/PDA coating with great corrosion protection, self-healing ability, bioactivity and biocompatibility could be a promising candidate for degradable magnesium-based implants.

文摘This article explores China’s state-level knowledge production on medicinal ingredients in northwestern Sichuan in the 1950s.Drawing on county-level archives,published materials and interviews,this historical article traces how different levels of governments and state-owned trading companies produced knowledge about medicinal ingredients and its production.It argues that on one hand the state’s procurement standards codified the knowledge about medicinal ingredients from the marketplace and the local producers.On the other hand,direct extraction of knowledge from the medicine gatherers and cultivators verbalized and collected the previously tacit local knowledge about the production of medicinal ingredients,which would help to alleviate the shortage in the supply of traditional Chinese medicines throughout the 1950s.
文摘[Objectives]To analyze the effect of Mongolian pharmaceutical Betel Shisanwei Ingredient Pills in the clinical treatment of patients with depression.[Methods]From June 2020 to May 2021,64 patients with depression who received treatment in Inner Mongolia Minzu University were selected to participate in this study.These patients were randomly numbered from 1 to 64,and then divided into two groups according to the principle of odd or even number.Patients with odd number were regarded as the reference group,and treated by western medicine fluoxetine;patients with even number were regarded as the study group,and treated by Mongolian pharmaceutical Betel Shisanwei Ingredient Pills.The therapeutic effects of the two groups of patients were compared.[Results]Before treatment,there was no significant difference in the scores of patients'depressive syndromes between the two groups(P>0.05).After treatment,there were two significant changes in comprehensive score of depressive symptoms in both groups.Compared with before treatment,the data of the same group after treatment decreased significantly.Comparison between the two groups showed that the score of patients'depressive syndromes in the study group(13.28±5.49)was significantly lower than that in the reference group(18.46±6.51),and the overall response rate of treatment in the study group(96.88%,31/32)was obviously higher than that in the reference group(75.00%,24/32),showing statistically significant differences(P<0.05).[Conclusions]In the treatment of depression,Mongolian medicine therapy can significantly improve the depressive syndromes in patients,with more prominent curative effects,and is worthy of promotion and application.
