Artifacts are often found in archaeological excavation sites mixed with each other randomly. Therefore, classifying them manually is a difficult task and time consuming because they commonly exceed thousands of fragments. Thus, the aim of this study is to find a solution for classification of ancient pottery into groups by computer assistance. This is a preparatory stage for the next phase, whi...

We present the results of a study performed on the interactions of 10.6A GeV gold nuclei in nuclear emulsions. In a minimum bias sample of 1311 interactions, 5260 helium nuclei and 2622 heavy fragments were observed as Au projectile fragments. The experimental data are analyzed with particular emphasis of target separation interactions in emulsions and study of critical exponents. Multiplicity ...

To evaluate the diagnostic pitfalls attributing to false suspicious interpretation of papillary thyroid carcinoma (PTC), we performed a retrospective cytohistologic review of thyroid nodules diagnosed as suspicious for papillary carcinoma with histology-proven false suspicion of PTC. A total of 22 thyroid fine needle aspirates along with the corresponding surgical specimens were reviewed. The p...

Epithelial cell adhesion molecule EpCAM is a transmembrane glycoprotein, which is highly and frequently expressed in carcinomas and (cancer-)stem cells, and which plays an important role in the regulation of stem cell pluripotency. We show here that murine EpCAM (mEpCAM) is subject to regulated intramembrane proteolysis in various cells including embryonic stem cells and teratocarcinomas. As sh...

We have studied the reconstitution of the Golgi apparatus in vivo using an heterologous membrane transplant system. Endogenous glycopeptides of rat hepatic Golgi fragments were radiolabeled in vitro with [3H]sialic acid using detergent-free conditions. The Golgi fragments consisting of dispersed vesicles and tubules with intraluminal lipoprotein-like particles were then microinjected into Xenop...

Despite her fame and cultural prominence as a Spanish dancer, Antonia Mercé La Argentina did not appear in major film projects, like many of peers. In this article, we examine the recent discovery footage contextualize these preserved fragments within development Western cinema presence imaginary industry time. These visual sources reveal how negotiated between art technology, stage screen, eco...

Bone morphogenetic protein-1 (BMP-1)/Tolloid-like metalloproteinases play key roles in formation of mammalian extracellular matrix (ECM), through the biosynthetic conversion of precursor proteins into their mature functional forms. These proteinases probably play a further role in formation of bone through activation of transforming growth factor beta-like BMPs. Dentin matrix protein-1 (DMP1), ...

SCUBE-1 is a newly identified, secreted cell surface protein that determined during early embryogenesis. This consists of cascading EGF-like repeats following the N-terminal signal peptide sequence, spacer region, cysteine-rich repeat motifs, and CUB domain at C-terminus. These molecules are stored in alpha granules inactivated platelets, translocated to platelet after activation by thrombin, a...

The neural cell adhesion molecule (N-CAM) engages in diverse functional roles in neural cell interactions. Its extracellular part consists of five Ig-like domains and two fibronectin type III homologous (type III) repeats. To investigate the functional properties of the different structural domains of the molecule in cell interactions and signal transduction to the cell interior, we have synthe...
