Soluble forms of human betacellulin (BTC) were purified to homogeneity from the conditioned medium of mouse A9 cells transfected with the BTC precursor cDNA. Three types of soluble BTC, designated BTC-la, BTC-lb and BTC-2, were resolved by cation-exchange and size-exclusion column chromatography. Physicochemical analysis has revealed that BTC-la represents the glycosylated, intact molecule comp...

zinc (ⅱ) tricarboxylate (zn-btc) with metal-organic framework (mof) has been synthesized for the first time under solvothermal conditions and has been tested as an adsorbent for methane and carbon dioxide at standard temperature and pressure. the adsorbent was characterized by means of x-ray diffraction(xrd), brunauer-emmet-teller (bet), fourier transform infrared (ft-ir) and scanning electron ...

Epidermal growth factor (EGF) family ligands have been implicated in cardiovascular diseases because of their enhanced expression in vascular lesions and their promoting effects on growth and migration of vascular smooth muscle cells (VSMCs). Betacellulin (BTC), a novel EGF family ligand, has been shown to be expressed in atherosclerotic lesions and to be a potent growth factor of VSMCs. Howeve...

BACKGROUND Heparin-binding epidermal growth factor (HB-EGF), betacellulin (BTC) and epiregulin (EPR) are members of the EGF system and involved in the cell growth of various epithelial malignancies. There have been no reports on the HB-EGF, BTC and EPR expression in mesenchymal malignancies of fibrohistiocytic origin including malignant fibrous histiocytoma (MFH). MATERIALS AND METHODS We inv...

BACKGROUND The green tea catechin epigallocatechin gallate (EGCG) was shown to effectively inhibit tumor growth in various types of cancer including biliary tract cancer (BTC). For most BTC patients only palliative therapy is possible, leading to a median survival of about one year. Chemoresistance is a major problem that contributes to the high mortality rates of BTC. The aim of this study was...

In order to reduce the frame memory usage in LCD overdrive, there is a basic technique called block truncation coding (BTC) is commonly used due to its efficient coding and low implementation cost. However, there is some limitation of BTC that causes severe perceptual artifacts and degrades overdrive performance. To overcome the problem of BTC here we propose an adaptive multi-level BTC (AM-BTC...

BACKGROUND Military research suggests a significant association between leadership, cohesion, mental health stigmatisation and perceived barriers to care (stigma/BTC). AIM Most studies are cross sectional, therefore longitudinal data were used to examine the association of leadership and cohesion with stigma/BTC. METHOD Military personnel provided measures of leadership, cohesion, stigma/BT...

Distinct regions of the frontal cortex connect with their basal ganglia and thalamic counterparts, constituting largely segregated basal ganglia-thalamo-cortical (BTC) circuits. However, any common role of the BTC circuits in different behavioral domains remains unclear. Indeed, whether dysfunctional motor and cognitive BTC circuits are responsible for motor slowing and cognitive slowing, respe...

In this paper, a cost effective block truncation coding (CE-BTC) using low cost approach is presented for color image compression. To reduce the bit rate of the basic BTC, selected single bit-map is employed to represent the edge information of the coding block in the proposed CE-BTC. Moreover, a previous proposed algorithm, adaptive quantization coding (AQC), is used to compress the two repres...

Rapid movement of agricultural chemicals through soil to groundwater via preferential flow pathways is one cause of water contamination. Previous studies have shown that time domain reflectometry (TDR) could be used to characterize solute transport in soil. However, previous studies have only scarcely addressed preferential flow. This study presents an extended application of TDR for determinin...
