Evidence of uterine atrophy, reduction in endometrial gland number, and inflammation and OS were seen in TBT miceFurther, strong negative correlations were observed between testosterone levels and primordial, primary, and total healthy ovarian follicles. Thus, these data suggest that the subchronic and low dose of TBT exposure impaired ovarian follicular reserve, uterine gland number, and other reproductive features in female mice. © The Author(s) 2020.

The purpose of this study was to understand factors that influence farmers' willingness to participate in agricultural product safety cogovernance and self-governance based on a survey of farmers in Jiangsu Province, China. The results show that farmers' willingness to participate in the cogovernance and self-governance of agricultural product safety must be further improved. Among the sampled farmers, 28.93% consider that other farmers' improper agricultural product safety practices have nothing to do with them, and 17.25% claim that they would not want to take part in agricultural product safety trainings.  https://www.selleckchem.com/products/AZD2281(Olaparib).html  Farmers with a weak appreciation for agricultural product safety hazards, a lack of food safety knowledge, and improper agricultural product safety practices are less willing to participate in cogovernance and self-governance of agricultural product safety. Female farmers are more willing to engage in agricultural product safety training than male farmers; however, their willingness to participate in agricultural product safety cogovernance is lower. The results of this study will be useful in improving food safety policy in China.

METHODS The study sample consisted of 599 adults aged 60 years and older meeting criteria for major depression or clinically significant minor depression. Longitudinal analysis via growth curve mixture modeling was carried out to classify patients as having worsening, persistent, or improving sleep over 1 year. RESULTS At 1-year follow-up, compared with patients with improving sleep, those with worsening sleep were more likely to have a diagnosis of major depression (adjusted odds ratio (aOR) = 28.60, 95% confidence interval (CI) 12.15 to 67.34), a diagnosis of clinically significant minor depression (aOR = 11.88, 95% CI 5.67 to 24.89), and suicidal ideation (aOR = 1.10, 1.005 to 1.199), and were half as likely to achieve remission (aOR = 0.52, 95% CI 0.46 to 0.57). Patients with persistent sleep disturbance showed similar but attenuated results. CONCLUSIONS Older primary care patients with depression who exhibit worsening or persistent sleep disturbance were at increased risk for persistent depression and suicidal ideation 1 year later. The pattern of sleep disturbance over time may be an important signal for exploration by primary care physicians of depression and suicidal ideation among older adults with depression. © Sleep Research Society 2020.

Cell proliferation, cell colony formation, cell cycle distribution, cell apoptosis and protein expression levels [double-strand break marker γ-H2AX, cell cycle-related protein cyclin B1, apoptosis-related proteins Bax and Bcl-2, and the Akt/mammalian target of rapamycin (mTOR)/ribosomal protein S6 kinase B1 (p70S6K) pathway] were detected after irradiation with carbon ions or X-rays at doses of 0, 2, 4 and 8 Gy. Our results showed that the inhibition of cell proliferation and cell colony formation and the induction of G2/M phase arrest, DNA lesions and cell apoptosis/necrosis elicited by carbon ion irradiation were more potent than the effects elicited by X-ray radiation at the same dose. Simultaneously, compared with X-ray radiation, carbon ion radiation induced a marked increase in Bax and prominent decreases in cyclin B1 and Bcl-2 in a dose-dependent manner. Furthermore, the Akt/mTOR/p70S6K pathway was significantly inhibited by carbon ion radiation in both breast cancer cell lines. These results indicate that carbon ion radiation kills MDA-MB-231 and MCF-7 breast cancer cells more effectively than X-ray radiation, which might result from the inhibition of the Akt/mTOR/p70S6K pathway. © The Author(s) 2020.

Sleep spindles are important brain waves associated with sleep protection and sleep-dependent memory consolidation. The present study tested whether sleep spindles are altered in individuals with PTSD and whether the findings are reproducible across nights and subsamples of the study. METHODS Seventy-eight combat-exposed veteran men with (n = 31) and without (n = 47) PTSD completed two consecutive nights of high-density EEG recordings in a laboratory. We identified slow (10-13 Hz) and fast (13-16 Hz) sleep spindles during N2 and N3 sleep stages and performed topographical analyses of spindle parameters (amplitude, duration, oscillatory frequency, and density) on both nights. To assess reproducibility, we used the first 47 consecutive participants (18 with PTSD) for initial discovery and the remaining 31 participants (13 with PTSD) for replication assessment.
