Oridonin, a compound from Rabdosia rubescens, has been shown to exhibit potent ability improve the antitumor effects of lentinan (LNT). In present study, oridonin, LNT, and combination these treatments were assessed on normal human fetal lung fibroblast cell line MRC?5, as well non?small cancer A549. Next, their metastasis survival in vivo mouse model cancer. The mRNA protein ...
Breast cancer is now the most common cancer in worldwide women, and novel interventions are needed to overcome the resistance occurring in the estrogen-targeted endocrine therapy. Herein, we demonstrate that the β-glucan from Lentinus edodes (LNT) exhibited a profound inhibition ratio of ∼53% against estrogen receptor positive (ER+) MCF-7 tumor growth in nude mice similar to the positive contro...
Contrary to previous empirical studies that find a linear link between economic conditions and presidential approval, this study argues for and finds a nonlinear relationship. A threshold regression is used to assess potential nonlinear relationships between macroeconomic variables and presidential popularity. A quarterly data analysis for the 1960Q1–2012Q2 time period reveals that domestic fac...
This paper analyzes the effects of trade openness on economic growth in a panel thirty developed and developing countries. The fixed model was estimated using PSTR technique data covering period 1980-2019. results show that relationship between is non-linear, external depend thresholds national income per capita. Below threshold 35 118 USD capita, has no significant effect growth. Above this th...
The conventional approach for radiation protection is based on the ICRP's linear, no threshold (LNT) model of radiation carcinogenesis, which implies that ionizing radiation is always harmful, no matter how small the dose. But a different approach can be derived from the observed health effects of the serendipitous contamination of 1700 apartments in Taiwan with cobalt-60 (T(1/2) = 5.3 y). This...
the biological effects of low-dose radiation exposure are increasingly better understood, continued research is needed to develop better individual risk-based models. Human population exposures to low doses of ionizing radiation (defined by the US Department of Energy as less than 10 rem or 0.1 Sv) are increasing due to occupational exposures of nuclear plant workers, waste managers and medical...
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
abstract this study examines the relationship between reading anxiety and difficulty of texts as well as the relationship between reading anxiety and students perceived difficulty of the texts. since difficulty is a relative concept, i limited its definition by sticking to the readability formula. we also took students perceived difficulty levels into account. therefore, in the present study, ...
