Although cisplatin-based chemotherapy has been used as the first-line treatment for ovarian cancer (OC), tumor cells develop resistance to cisplatin during treatment, causing poor prognosis in OC patients. Studies have demonstrated that overactivation of phosphatidylinositol 3-kinase/protein kinase B/mammalian target rapamycin (PI3K/AKT/mTOR) pathway is involved chemoresistance and overexpression microRNA-497 (miR497) may overcome by inhibiting mTOR pathway. However, low transcriptional...
A one-dimensional iterative chaotic map with infinite collapses within symmetrical region [-1, O)/spl cup/(O, +1] is proposed. The stability of fixed points and that around the singular point are analyzed. Higher Lyapunov exponents proposed show stronger characteristics than some continuous models usually used. There exist inverse bifurcation phenomena special main periodic windows at certain positions shown in diagram, which can explain generation mechanism chaos. model good properties be...
Target-based screening is one of the major approaches in drug discovery. Besides intended target, unexpected off-target interactions often occur, and many them have not been recognized characterized. The can be responsible for either therapeutic or side effects. Thus, identifying genome-wide off-targets lead compounds existing drugs will critical designing effective safe drugs, providing new opportunities repurposing. Although computational methods developed to predict drug-target...
Gambogic acid (GA) is a major active ingredient of gamboge, widely used traditional Chinese medicine that has been reported to be potent cytotoxic agent against some malignant tumors. Many studies have shown the NF-kappa B signaling pathway plays an important role in anti-apoptosis and drug resistance tumor cells during chemotherapy.

Chain-of-Thought (CoT) prompting has emerged as a powerful technique for enhancing language model's reasoning capabilities. However, generating long and correct CoT trajectories is challenging. Recent studies have demonstrated that Looped Transformers possess remarkable length generalization capabilities, but their limited generality adaptability prevent them from serving an alternative to auto-regressive solutions. To better leverage the strengths of Transformers, we propose RELAY...
We propose a novel spectrum-sensing method for cognitive radio (CR) based on stochastic resonance (SR). The spectral power of primary users (PUs) can be amplified, and the signal-to-noise ratio (SNR) received signal increased using SR. This ensures that detection probability proposed approach is higher than traditional energy detector. also theoretically derived under constant false-alarm rate (CFAR). Performance analyses computer simulation results show effectiveness SR-based approach,...
