BACKGROUND Treatment failure during venom immunotherapy (VIT) may be associated with a variety of risk factors. OBJECTIVE Our aim was to evaluate the association of baseline serum tryptase concentration (BTC) and of other parameters with the frequency of VIT failure during the maintenance phase. METHODS In this observational prospective multicenter study, we followed 357 patients with estab...
Residually thin and nilpotent table algebras, which are abstractions of fusion rings adjacency algebras association schemes, defined investigated. A formula for the degrees basis elements in residually is established, yields an integrality result Gelaki Nikshych as immediate corollary; it shown that this holds only such algebras. These theorems specialize to new results schemes. Bi-anchored thi...
Cholangiocarcinoma (CCA) is the most common malignant heterogeneous polygenetic carcinoma with a high incidence in Asia. Most patients would die within 1 year after diagnosis and the 5 year survival rate is less than 10-20% worldwide. Single nucleotide polymorphisms (SNPs) in genes regulate telomere maintenance, mitosis, and inflammation, and may help predict individual susceptibility to certai...
Block truncation coding (BTC) [1] is an efficient image coding method that has been adopted to obtain the statistical properties of a block in image compression. Low computational complexity and superior channel error resisting ability make it attractive in real-time image compression. The BTC output data set includes a binary bit plane, which defines the quantization level of each pixel, and t...
BASIC THRESHOLDING CLASSIFICATION Toksöz, Mehmet Altan Ph.D., Department of Electrical and Electronics Engineering Supervisor : Assoc. Prof. Dr. İlkay Ulusoy March 2016, 128 pages In this thesis, we propose a light-weight sparsity-based algorithm, basic thresholding classifier (BTC), for classification applications (such as face identification, hyperspectral image classification, etc.) which is...
BACKGROUND Since sorafenib has shown activity in different tumour types and gemcitabine regimens improved the outcome for biliary tract cancer (BTC) patients, we evaluated first-line gemcitabine plus sorafenib in a double-blind phase II study. PATIENTS AND METHODS 102 unresectable or metastatic BTC patients with histologically proven adenocarcinoma of gallbladder or intrahepatic bile ducts, E...
Biliary tract carcinomas (BTC) are malignant tumors with limited therapeutic options. Clinical experiences with anti-EGFR therapies have produced unsatisfactory results. The strategies of combined inhibition of EGFR and MEK1/2 could be a promising therapeutic option in BTC treatment. Preclinical activity of Panitumumab and Trametinib was tested in in vitro (EGI-1, MT-CHC01 and WITT cells) and i...
Green tea and coffee consumption may decrease the risk of some types of cancers. However, their effects on biliary tract cancer (BTC) have been poorly understood. In this population-based prospective cohort study in Japan, we investigated the association of green tea (total green tea, Sencha, and Bancha/Genmaicha) and coffee consumption with the risk for BTC and its subtypes, gallbladder cancer...
The aggregation behavior of the ionic liquid (IL) 1-alkyl-3-methylimidazolium chloride with different alkyl chain lengths in a deep eutectic solvent (DES, composed of choline chloride and glycerol in a 1 : 2 mole ratio) was studied for the first time. The critical micellar concentration, micellar size and intermolecular interactions in IL/DES solutions were investigated by different techniques ...
Biliary tract cancers (BTC), including cholangiocarcinoma and gallbladder cancer, are poor-prognosis and low-incidence cancers, although the incidence of intrahepatic cholangiocarcinoma is rising. A minority of patients present with resectable disease but relapse rates are high; benefit from adjuvant capecitabine chemotherapy has been demonstrated. Cisplatin/gemcitabine combination chemotherapy...
