Objectives To compare a calcium silicate and sodium phosphate toothpaste (CSSP) with a fluoride negative control toothpaste for dentine hypersensitivity (DH) pain reduction after 14, 28 and 29 days. Methods This was a double blind, parallel study in 247 healthy adults with DH (Schiff score >2, tactile 10-20 g) in 2 teeth in different quadrants of the mouth. After acclimatisation, participants were randomised to CSSP or control toothpaste. After measuring baseline sensitivity products were applied twice-daily by toothbrushing, and once daily massaging into the sensitive teeth. Sensitivity was assessed following airblast (Schiff and VAS) and tactile (Yeaple probe) stimuli at baseline, 14 and 28 days, and at 29 days, 12 h after last product application. Participants completed a quality of life questionnaire at each study visit up to day 28. Results After 14, 28 and 29 days the CSSP group had significantly lower Schiff, lower VAS and higher Yeaple probe scores compared to control (VAS at 14 days, p less then 0.04; all other comparisons, p less then 0.001). Quality of life scores improved in both groups, but no significant differences between groups were observed. Conclusions The CSSP toothpaste was more effective than the fluoride control toothpaste at reducing DH pain with benefit persisting 12 h following application. Clinical significance This novel calcium silicate and sodium phosphate toothpaste (CSSP) toothpaste is an effective twice-daily treatment when brushed on the teeth for dentine hypersensitivity sufferers compared to brushing with a conventional fluoride paste. Twice-daily brushing provides a sustained effect for long-lasting pain relief from dentine hypersensitivity.Background/objective Inflammation is implicated in cognitive decline; however, there is a paucity of data for African American populations and for sex-specific associations. Design Prospective cohort study. Setting Genetic Epidemiology Network of Arteriopathy/Genetics of Microangiopathic Brain Injury studies. Participants African-American sibships (N = 1010). Measurements Neurocognitive tests assessed global cognition and four cognitive domains processing speed, memory, language, and executive function at two time points over seven years. Circulating levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor receptor (TNFR)-1 and TNFR2 were measured at study baseline. Linear mixed models were used to investigate the association between inflammation markers and cognitive decline. Results Among men, a one SD increase in CRP was associated with an increased rate of decline over 7 years in global cognitive Z-score (adjusted difference in slopes = -0.31, p = 0.006) and in processing speed Z-score (adjusted difference in slopes = -0.10, p = 0.02), but not declines in memory, language, or executive function Z-scores. Also among men, a one SD increase in IL-6 was associated with an increased decline rate in global cognitive Z-score (adjusted difference in slopes = -0.33, p = 0.002) and in processing speed Z-score (adjusted difference in slopes = -0.12, p = 0.007). There was no difference in decline rates by CRP or IL-6 level in adjusted analyses among women for any cognitive scores. Among men and women combined, a one SD increase in baseline sTNFR1 was associated with a faster rate of decline in memory Z-score (adjusted difference in slopes = -0.09, p = 0.02). Baseline sTNFR2 levels did not significantly predict rate of cognitive decline in any cognitive domains. Conclusions Circulating markers of CRP and IL-6 may be differential risk factors for men and women in relation to cognitive decline. A novel inflammation marker, sTNFR1, may be a useful predictor of memory decline in older adults.Autophagy is a catabolic process for cells that can provide energy sources and allows cancer cells to evade cell death. Therefore, studies on the combination of autophagy inhibitors with drugs are increasing as a new treatment modality in cancer. Previously, we reported the anti-tumor activity of a Palladium (Pd)(II) complex against different types of cancer in vitro and in vivo. Chloroquine (CQ), the worldwide used anti-malarial drug, has recently been focused as a chemosensitizer in cancer treatment. The aim of this study was to investigate the efficacy of a combined treatment of these agents that work through different mechanisms to provide an effective treatment modality for metastatic prostate cancer that is certainly fatal. Metastatic prostate cancer cell lines (PC-3 and LNCaP) were treated with Pd (II) complex, CQ, and their combination. The combination enhanced apoptosis by increasing phosphatidylserine translocation and pro-apoptotic proteins. Apoptosis was confirmed by the use of apoptosis inhibitor. The formation of acidic vesicular organelles (AVOs) was observed by acridine orange staining in fluorescence microscopy.  https://www.selleckchem.com/products/PD-98059.html  The Pd (II) complex increased AVOs formation in prostate cancer cells and CQ-pretreatment has potentiated this effect. Importantly, treatment with CQ suppressed the pro-survival function of autophagy, which might have contributed to enhanced cytotoxicity. In addition, PI3K/AKT/mTOR-related protein expressions were altered after the combination of treatments. Our results suggest that combination treatment enhances apoptotic cell death possibly via the inhibition of autophagy, and may therefore be regarded as a novel and better approach for the treatment of metastatic prostate cancer.Entrectinib is a new tyrosine kinase inhibitor that was recently approved for the treatment of ROS1-positive metastatic non-small cell lung cancer (NSCLC). In this study, we aimed to characterize its potential to act as a modulator of pharmacokinetic cytostatic resistance and perpetrator of drug interactions. In accumulation studies, entrectinib exhibited potent inhibition of ABCB1, while only moderate interaction was recorded for ABCG2 and ABCC1 efflux transporters. Furthermore, incubation assays revealed the potential of this drug to inhibit various recombinant cytochrome P450 enzymes, which can be ranked according to inhibitory affinities as follows CYP2C8 ≈ CYP3A4 > CYP2C9 > CYP2C19 ≈ CYP3A5 > CYP2D6 > CYP2B6 > CYP1A2. Additionally, in silico docking analysis confirmed entrectinib's interactions with ABCB1 and CYP3A4 and resolved their possible molecular background. In subsequent drug combination experiments, we demonstrated the ability of entrectinib to synergize with daunorubicin in various ABCB1-expressing cellular models.
