Trigonelline's effect on BCL-2 protein expression level in THP-1 cells
(Elsevier, 2019)
Objective: Trigonelline (TRG), is one of the main constituents of coffee and is an alkaloid derivative of vitamin B6 in plants. TRG has been reported to have antihyperglycemic, antihyperlipidemic, and antioxidant activities. ...
Systemic inflammatory markers as a predictors of response to crizotinib in patients with ALK-positive non-small-cell lung cancer
(Elsevier Science Inc, 2019)
The significance of the presence of a systemic inflammatory response (SIR) in predicting survival has been demonstrated in patients with cancer. Moreover, neutrophil-to-lymphocyte ratio (NLR), lymphocyteratio (NLR), ...
Comparison of machine learning techniques on MS lesion segmentation
(Institute of Electrical and Electronics Engineers Inc., 2019)
Multiple sclerosis arises with conformational change in myelin sheath. Magnetic resonance imaging is frequently used in detection of MS. In this study, to figure out MS lesion, machine learning techniques, namely k means ...
Compressed spectrum sensing using sparse recovery convergence patterns through machine learning classification
(Institute of Electrical and Electronics Engineers Inc., 2019)
Despite the well-known success of sub-Nyquist sampling in reducing the hardware and computational costs of spectrum sensing, it still has the shortcoming of requiring a pre-determined spectrum sparsity level. This paper ...
The evaluation of FFR for interference management in coordinated hybrid terrestrial-aerial network
(Institute of Electrical and Electronics Engineers Inc., 2019)
Recent works have tried to incorporate unmanned aerial vehicle (UAV) base stations in conventional networks, however, the inter-cell interference mitigation techniques for such networks have not been studied comprehensively. ...
