The plant Polygonum aviculare L. (Polygonaceae) is an annual herbaceous plant which is known to be beneficial for treating gastroduodenal ulcer, hypertension, diarrhea, hemorrhage, and hemorrhoids. Ten phenolic compounds, including nine flavonoids (myricetin, quercetin, kaempferol, myricitrin, desmanthin-1, isoquercitrin, quercitrin, avicularin, juglanin), and gallic acid were used for simultaneous HPLC quantification and peroxynitrite-scavenging assay. Simultaneous quantification of these substances were performed on five extracts (EtOH-, MeOH-, 70% MeOH-, 30% MeOH-, and H2O extracts) as well as on the three fractions (Et2O-, EtOAc-, and BuOH fractions), under the condition of a Capcell Pak C18 column (5μm, 250mm×4.6mm i.d.) and a gradient elution of 0.05% trifluoroacetic acid (TFA) and MeOHCH3CN (60:40). Of the three fractions, the EtOAc fraction displayed the highest content of flavonoids (sum, 208.9mg/g) with the strongest peroxynitrite-scavenging activity (IC50, 2.68μg/mL). The activities of the eight compounds (myricitrin, isoquercitrin, avicularin, quercitrin, myricetin, desmanthin-1, quercetin, and kaempferol) were comparable to that of the positive control (l-penicillamine; IC50: 1.03μg/mL). These results suggest that folkloric medicinal uses of P. aviculare are mainly attributed to flavonoids, such as particularly highly contained myricetin, myricitrin, and desmanthin-1. © 2013.

Inexpensive Ni-Sn-based alloy catalysts, both bulk and supported, exhibited high selectivity in the hydrogenation of a wide range of unsaturated carbonyl compounds and produced unsaturated alcohols almost exclusively. For the bulk Ni-Sn alloy catalysts, a relatively high reaction temperature of 453 K was required to achieve an efficient hydrogenation of CO rather than CC. The catalyst that consisted of the Ni-Sn alloy dispersed on TiO2 allowed a remarkable reduction of the reaction temperature to 383 K. Both the Ni 3Sn2 and Ni3Sn alloy phases were found to be responsible for the enhancement of the chemoselectivity. The Ni-Sn alloy catalysts were reusable without any significant loss of selectivity. © 2012 The Royal Society of Chemistry.

Effective production of hexitols (sorbitol and mannitol) was achieved from sugars by means of nickel nano-particles supported on aluminium hydroxide (NiNPs/AlOH) catalyst. NiNPs/AlOH catalyst was prepared by a simple and benign environmentally procedure using less amount of sodium hydroxide. ICP-AES and XRD analyses confirmed that the NiNPs/AlOH catalysts comprised a large amount of remained aluminium hy-droxide (i.e. bayerite and gibbsite). The presence of aluminium hydroxide caused a high dispersion Ni metal species. The average Ni crystallite sizes that derived from the Scherrer's equation for former R-Ni and NiNPs/AlOH were 8.6 nm and 4.1 nm, respectively. The catalyst exhibited high activity and selectivity both hydrogenolysis of disaccharides (sucrose and cellobiose) and monosaccharides (glucose, fructose, and xylose) at 403 K for 24 h. The NiNPs/AlOH catalyst was found to be reusable for at least five consecutive runs without any significant loss of activity and selectivity. © 2013 BCREC UNDIP.

This paper focuses on hydro-mechanical behavior (i.e., suction characteristic and swelling pressure) of thermal treated bentonite. Calcium type bentonite (Calcigel) was used in the experimental study. The specimens were heated to temperatures of 100, 200, 300, 400, and 500°C. Change in minerallogy of specimen was quantified using X-ray diffraction analysis. Chilled-mirror hygrometer technique was used to determine total suction of the pre-heated specimen at room temperature. Swelling pressure was measured applying constant volume swelling pressure method. The results show that the ability of pre-heated specimen to retain water decreases after heating to temperature higher than 100 due to dehydration and dehydroxylation processes. Pre-heated process does not only influence the value of swelling pressure but also the rate of swelling pressure up built during the test. © 2011 Taylor & Francis Group, London.

Hydroxyapatite is chemically related to the inorganic component of bone matrix as a complex structure with the formula of Ca10(OH) 2(PO4)6. Previous studies have reported the application of microsized hydroxyapatite to bone regeneration, but the result is not satisfied. The limitation comes from the size of hydroxyapatite. In addition, the duration of treatment is very long. The advantages of hydroxyapatite nanocrystal are the osteoconduction, bioresorption, and contact in close distance. Crystal in osteoporotic bone is calcium phosphate hydroxide with the chemical formula of Ca10(OH)2(PO 4)6. Crystal of normal bone is sodium calcium hydrogen carbonate phosphate hydrate with the chemical formula of Ca8H 2(PO4)6·H2O-NaHCO 3-H2O. The recent development is applying nanobiology approach to hydroxyapatite. This is based on the concept that the mineral atoms arranged in a crystal structure of hydroxyapatite can be substituted or incorporated by the other mineral atoms. In conclusion, the basic elements of hydroxyapatite crystals, composed of atomic minerals in a certain geometric pattern, and their relationship to the bone cell biological activity have opened opportunities for hydroxyapatite crystals supplement application on osteoporosis. Understanding of the characteristics of bone hydroxyapatite crystals as well as the behavior of mineral atom in the substitution will have a better impact on the management of osteoporosis. © 2013 Zairin Noor.

Objective: To investigate whether the CNS1S2 protein of goat milk is able to inhibit the toxicity of methyl glyoxal (MG) towards MC3T3E1 pre-osteoblast cells. Methods: At confluency, pre-osteoblast cells were divided into five groups which included control (untreated), pre-osteoblast cells exposed to 5 μmol/L MG, pre-osteoblast cells exposed to MG in the presence of CSN1S2 protein at doses of 0.025, 0.050, and 0.100 mg/L, respectively. Analysis of reactive oxygen species was done with 2,7-dichlorodihydrofluorescein diacetate fluorochrome. The proliferation and viability of MC3T3E1 cells were measured by trypan blue staining. Malondialdehyde analysis was done colorimetrically. Results: Cell's viabilities were significantly lower in MG+0.050 mg/L CSN1S2 protein of goat milk compared to MG group (P<0.05). MG+0.100 mg/L CSN1S2 protein of goat milk significantly increased the cells viability compared to MG group (P<0.05). The levels of proliferation were significantly higher in MG+0.100 mg/L CSN1S2 protein of goat milk compared to control group and all treatment groups, respectively (P<0.05). Conclusions: High dose of CSN1S2 protein of goat milk (0.100 mg/L) in high MG environment inhibits the decrease of viability due to the increases of the proliferation of MC3T3E1 pre-osteoblast cell. © by the Asian Pacific Journal of Tropical Disease.

The depth of waters has a close correlation with intensity of sunlight and waters’ temperature. The deeper the waters from the surface, the less light intensity be received. As a result, temperature also decreases at the deeper layer. This certainly gives effect on the abundance and the body size of giant sea anemones. The purpose of this study is to find out the relationship of the depth of waters to the distribution of abundance and body size of the giant sea anemones in the waters of Teluk Tamiang village, south Kalimantan, Indonesia. Study sites were divided into five stations: three stations in the western part of the waters and two stations in the eastern part of the waters of Teluk Tamiang. Each station was subdivided into three depths: 0-2 m, > 2-4 m, and > 4-6 m. Data of relative abundance and body size of giant sea anemones at different depths were analyzed using Kruskal Wallis test. Distribution of abundance and body size of giant sea anemones based on depths was analyzed using Correspondence Analysis. The results showed that there were three species of giant sea anemones found, namely Stichodactyla gigantea, Entacmaea quadricolor and Heteractis crispa. The abundance and body size of S. gigantea were higher than those of E. quadricolor and H. crispa. However, the distribution of abundance and body size anemones had no significant difference among the depths of waters. © 2016, BIOFLUX SRL. All rights reserved.
