Both β-catenin (β-cat) and osterix (OSX) are known to be essential for embryonic and postnatal osteoblast differentiation and bone growth. In the present study, we explored the crosstalk between β-cat signaling and OSX, and assessed its effect on the osteoblastogenic differentiation of human pre-osteoblastic cells (MG-63) and bone marrow stromal cells (HS-27A). In the HS-27A and MG-63 cells, th...
dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...
the bioactivity of chemical extracts from silverleaf nightshade solanum elaeagnifolium cav. seeds and leaves were tested for herbicidal activities, through water and ethanol extracts, against portulaca oleracea l., corchorus olitorius l., convolvulus arvensis l.and echinochloa crus-galli (l.) found in most zea mays l.fields. characterization of the isolated constituents from ethanol extract was...
phytochemical investigations of piper sarmentosum roxb., yielded four compounds; three amides, identified as 3-(3’,4’,5’-trimethoxyphenylpropanoyl) pyrrolidine, 3-(4’-methoxyphenylpropanoyl) pyrrole, n -(3-phenylpropanoyl) pyrrole and a sterol namely β -sitosterol . 3-(4’-methoxyphenylpropanoyl) pyrrole was found for the first time in this piper species. all chemical constituents were tested fo...
SiO2/MgCl2 (ethoxide type)/TiCl4 Ziegler-Natta catalysts for use in ethylene polymerization and ethylene/1-hexene copolymerization have been prepared using silica with a supported layer of magnesium ethoxide (Mg(OEt)2) as a catalyst precursor, followed by treating with TiCl4 at different Ti/Mg molar ratios, which showed significant effects on the active centers and pore structures of the cataly...
Background: Senile dementia is the most common kind of dementia with considerable social and economic costs. Since the nature of disease is multi-pathological, current treatments cannot cover all aspects of the disease. Recently, scientific considerations have focused on the role of natural products, especially those with traditional backgrounds. Objective: to review natural treatments of demen...
Peganum harmla L. (Zygophyllaceae) is one of the components of an ethnobotanical preparation used in the treatment of neoplasms in Iran. β -carboline alkaloids like harmaline and harmine are the major constituents of P. harmla L. seeds extract. MTT-colorimetric assay was used in this study to investigate cytotoxicity of P. harmala seeds extract and its β -carboline alkaloids against HFFF-P16,...
the present work was designed to study the antioxidant activity and to identify the main active components of the essential oil of ajowan (trachyspermum copticum) fruit. gc and gc-ms analyses of the essential oil showed the presence of eight compounds. the main constituents of the oil were thymol (43.7%), p-cymene (26.8%), and γ-terpinene (24.9%). the antioxidant and free radical scavenging act...
Wnt/β-catenin signaling plays a key role in the pathogenesis of colon and other cancers; emerging evidence indicates that oncogenic β-catenin regulates several biological processes essential for cancer initiation and progression. To decipher the role of β-catenin in transformation, we classified β-catenin activity in 85 cancer cell lines in which we performed genome-scale loss-of-function scree...
