Unburned carbon in fly ash is an important by-product from coal combustion. In this investigation, unburned carbon has been separated from fly ash and been employed as a low cost adsorbent for a basic dye adsorption (Rhodamine B) in aqueous solution. Adsorption isotherm and kinetics of adsorption have been investigated using batch experiments. It is found(More)
The potential impact of titanium dioxide nanoparticles (TiO2 NPs) on nitrogen removal from wastewater in activated sludge was investigated using a sequencing batch reactor. The addition of 2–50 mg L−1 of TiO2 NPs did not adversely affect nitrogen removal. However, when the activated sludge was exposed to 100–200 mg L−1 of TiO2 NPs, the effluent total(More)
The mechanism of reproductive behavior and sperm competition strategy in Helicoverpa armigera (Hübner) has been an interesting topic for quite some time. In the current study, sperm motility pattern and sperm competition in H. armigera were investigated. The majority ofapyrene and eupyrene sperm from spermatophore were simultaneously transferred to(More)
The objective of the present study was to identify chemical constituents of volatile oil from Pyrolae herba (PHVO) and evaluate the antiproliferative activity of PHVO against SW1353 human chondrosarcoma cells. The volatile oil from Pyrolae herba was prepared by hydrodistillation and characterized by gas chromatography-mass spectroscopy (GC-MS). A total of(More)
It has been recently shown that polysaccharides isolated from plants exhibit a number of beneficial therapeutic properties. Bauhinia championii (Benth.) Benth. has been widely used for the clinical treatment of knee osteoarthritis (OA) in China. However, the underlying molecular mechanisms of knee OA treatment have yet to be elucidated. In the present(More)
We have previously reported that Tougu Xiaotong capsule (TXC) inhibits tidemark replication and cartilage degradation by regulating chondrocyte autophagy in vivo. Autophagy, a cell protective mechanism for maintaining cellular homeostasis, has been shown to be a constitutively active and protective process for chondrocyte survival. However, it remains(More)
The tidemark is located between calcified and non-calcified cartilage matrices. Tidemark replication plays an important role in the pathogenesis of osteoarthrosis (OA). Autophagy, or cellular self-digestion, is an essential cellular homeostasis mechanism that was found to be deficient in osteoarthritic cartilage. This study evaluated the effects of Tougu(More)
Whether Neo-adjuvant chemotherapy can affect patients' postoperative brain function is not clear. In this study, we investigated the effect of preoperative cisplatin treatment on postoperative cognitive function and its possible mechanism in rats. Moreover, we also tested whether the NMDAR inhibitor memantine could attenuate cisplatin-induced alterations.(More)
Millimeter waves, high-frequency electromagnetic waves, can effectively alleviate the clinical symptoms in osteoarthritis patients, as a non-pharmaceutical and non-invasive physical therapy regimen. However, the molecular mechanisms of the therapeutic effects of millimeter wave treatment are not well understood. In the present study, the effect of(More)
