The objective of this study is to analyze the effect of Task-Technology Fit in Perceived Usefulness and Ease of Use of a Distance Education system (Moodle) and assess whether this approach leads to a good explanation of Intention to Use, even in the condition of mandatory adoption. Therefore, following a tradition in this field, a reduced combined model was proposed and tested associating TAM a...
OBJECTIVE To identify lipid markers of blastocyst formation by day three culture medium mass spectrometry (MS) fingerprinting. METHODS For this study, 50 embryo samples from culture media were harvested on day three, from patients undergoing embryo transfers on day five. Samples were split into groups based on their degree of expansion and hatching status on day five (Complete-Blastocyst, n=2...
Heshouwu (HSW), the dry roots of Polygonum multiflorum, a classical traditional Chinese medicine is used as a tonic for a wide range of conditions, particularly those associated with aging. However, it tends to be taken overdose or long term in these years, which has resulted in liver damage reported in many countries. In this study, the indicative roles of nine bile acids (BAs) were evaluated ...
Multiple Myeloma (MM) is a severely debilitating neoplastic disease of B cell origin, with the primary source of morbidity and mortality associated with unrestrained bone destruction. Surface enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS) was used to screen for potential biomarkers indicative of skeletal involvement in patients with MM. Serum samples from 4...
مقدمه: دیابت یکی از شایعترین بیماریها در دنیا می‌باشد. روشهای تشخیص این بیماری پرهزینه و نیازمند نمونه‌گیری از خون بیمار می‌باشد. یکی از روشهای نوین تشخیص دیابت آنالیز طیف موی سر است. هدف ما در این پژوهش استفاده از لیزر و علم بیناب‌نمایی برای تشخیص کمهزینه و بدون نیاز به مواد مصرفی برای تشخیص سریع دیابت است. روش بررسی: در این پژوهش، بهمنظور تشخیص دیابت بهوسیلۀ آنالیز موی سر توانایی روش ...
سرطان ریه علت اصلی مرگ و میر ناشی از سرطان در جهان است. سرعت مرگ و میر زیاد در نتیجه ی فقدان ابزار موثر برای تشخیص این بیماری در مراحل اولیه است. گفته شده است که سیگار کشیدن باعث ایجاد تفاوت در الگوی بیان ژن افراد بدون سرطان ریه و افراد دارای سرطان ریه می شود. در این پژوهش سعی شد که با استفاده از الگوی بیان ژن افراد سیگاری دارای سرطان ریه و بدون سرطان ریه، با استفاده از کمومتریکس مدل هایی برای ...
Phototherapy has been widely used in treating neonatal jaundice, but detailed metabonomic profiles of neonatal jaundice patients and response to phototherapy have not been characterized. Our aim was to depict the serum metabolic characteristics of neonatal jaundice patients relative to controls and changes in response to phototherapy. A (1) H nuclear magnetic resonance (NMR)-based metabonomic a...
1H NMR-based metabolic profiling combined with multivariate data analysis was used to explore the metabolic phenotype of functional dyspepsia (FD) in stressed rats and evaluate the intervention effects of the Chinese medicine Weikangning (WKN). After a 7-day period of model establishment, a 14-day drug administration schedule was conducted in a WKN-treated group of rats, with the model and norm...
Máquinas de vetor de suporte por mínimos quadrados (LS-SVM) e mínimos quadrados parciais (PLS) têm recebido atenção considerável em quimiometria para análise multicomponente. Foi realizada uma comparação entre os métodos LS-SVM e PLS aplicando-os na determinação espectrofotométrica simultânea de cipermetrina, permetrina e tetrametrina. Os espectros de absorbância no UV de soluções metanólicas f...
