Background: Imatinib is an antineoplastic agent acting as a tyrosine kinase inhibitor to treat cancer such as lymphoblastic leukemia. The dosage of the anticancer drugs plays a critical role in the survival of the patients. For this reason, the patient's plasma and urine samples should be monitored to obtain the necessary information regarding the toxicity of the drug. In this study, the applic...
This paper introduces a novel method that allows fast and reliable extraction of material parameters in terahertz time-domain spectroscopy. This method could be applied for most of materials and requires neither simplifying assumptions nor samples of different thickness for the extraction. The presented extraction procedure operates either on truncated terahertz signals when temporal windowing ...
background: the extraction of teeth for orthodontic purpose has always been a controversial subject in the speciality. the aesthetics impact of the soft-tissue profile might play a key role in deciding on premolar extraction or non-extraction (ne) treatment, particularly in borderline patients. the purpose of this cephalometric study was to examine the soft-tissue treatment effects of class ii ...
Porous agar materials have been prepared from marine macroalgae species using a simple microwave-assisted extraction/drying methodology, providing a new family of polysaccharide derived porous solids. The microwave-assisted extraction allows a more efficient and less time-consuming extraction of the polysaccharide compared to conventional extraction protocols based on conventional heating. DRIF...
Abstract Introduction: The aim of this study was to identify the antibacterial components in the ethanol extraction of Aloe vera against four clinically frequent pathogenic bacteria. Materials and Methods: In this in-vitro study, Aloe vera extraction was prepared by dissolving 500 grams of the powder in 5L of 95% ethanol. The antibacterial activity of the extraction against Staphylococcus a...
Sub-gap density of states (DOS) is a key parameter to impact the electrical characteristics of semiconductor materials-based transistors in integrated circuits. Previously, spectroscopy methodologies for DOS extractions include the static methods, temperature dependent spectroscopy and photonic spectroscopy. However, they might involve lots of assumptions, calculations, temperature or optical i...
purpose : to report a study design for assessing the cataract surgery outcome methods : we conducted the study in an eye hospital in which over 13,300 cataract extractions are performed annually. sampling framework and recruitment included international classification of diseases (icd)-10-based electronic hospital records of patients who underwent age-related cataract extraction within the prec...
Background and purpose: Colchicum kurdicum (Bornm.) Stef. is a monocotyledon plant which is endemic to Iran. The corm and seeds of this plant have some bioactive compounds, especially tropolone alkaloids that are used in treatment of inflammations, rheumatoid arthritis, gout, joint pains, and cancers. This study aimed at optimization of colchicine extraction from the corms of C. kurdicum and ev...
Update summarization is a new challenge which combines salience ranking with novelty detection. Previous researches usually convert novelty detection to the problem of redundancy removal or salience re-ranking, and seldom explore the birth, splitting, merging and death of aspects for a given topic. In this paper, we borrow the idea of evolutionary clustering and propose a three-level HDP model ...
background: the aim of this study was to determine the pattern and amount of change exhibited in mandibular intercanine and intermolar width during treatment and assessing its stability1-3 years post-retention. materials and methods: the material consisted of 70 cases of which 20 cases were treated without extraction and 30 cases were treated with extraction, which were compared with 20 untreat...
