Thus, high HCC potentiated both forms of disrupted interaction. Results raised questions about the meaning of very low reported depressive symptoms, and underscored the importance of chronic stress physiology and maternal depressed mood as risk factors for distinct forms of maternal disrupted interaction, both of which are deleterious for infant development. © 2020 Wiley Periodicals, Inc.BACKGROUND AND PURPOSE Proton treatment planning relies on an accurate determination of stopping-power ratio (SPR) from x-ray computed tomography (CT). A refinement of the heuristic CT-based SPR prediction using a state-of-the-art Hounsfield look-up table (HLUT) is proposed, which incorporates patient SPR information obtained from dual-energy CT (DECT) in a retrospective patient-cohort analysis. MATERIAL AND METHODS SPR datasets of 25 brain-tumor patients, 25 prostate-cancer patients, and three nonsmall cell lung-cancer (NSCLC) patients were calculated from clinical DECT scans with the comprehensively validated DirectSPR approach. Based on the median frequency distribution of voxelwise correlations between CT number and SPR within the irradiated volume, a piecewise linear function was specified (DirectSPR-based adapted HLUT). Differences in dose distribution and proton range were assessed for the nonadapted and adapted HLUT in comparison to the DirectSPR method, which has been shown to be an accurate and relirediction (HLUT), and represents a further step toward full integration of the DECT-based DirectSPR method for treatment planning in proton therapy. © 2020 American Association of Physicists in Medicine.Natural killer cells, which play a pivotal role in the establishment and maintenance of normal pregnancy, are the most abundant leukocytes at the fetomaternal interface that their subsets frequencies and cytokine profile are influential factors in the preservation of the decidual tolerogenic microenvironment. Any imbalance in NK cells' frequency and functions could be associated with pregnancy failure. Mesenchymal stem cells (MSCs) are shown to have immunomodulatory effects on NK cells and their cytokine profile. The purpose of this study is to evaluate the impact of MSCs therapy on the cytokine profiles and subpopulations of NK cells in a murine model of recurrent pregnancy loss. Adipose-derived MSCs were injected intraperitoneally to the abortion-prone mice on Day 4.5 of gestation. The abortion rate was determined after MSCs administration and the frequency and cytokine profiles of the different subsets of NK cells were determined using the flow cytometry. Our results showed that, in abortion-prone mice, the frequency of CD49b+ NK cells was significantly higher than normal pregnant mice that decreased after therapy. We also demonstrated that MSCs downregulated the production of IFN-γ and upregulated IL-4 and IL-10 production by uNK cells. These findings indicate that MSCs can decrease the infiltration of CD49b+ NK cells to the fetomaternal interface and modulate the cytokine profile of NK cells from inflammatory to tolerogenic profile and thereby improve the tolerogenic microenvironment at the fetomaternal interface in benefit of pregnancy maintenance. © 2020 Wiley Periodicals, Inc.Protein aggregation plays a central role in numerous neurodegenerative diseases. The key proteins in these diseases are of significant importance, but their investigation can be challenging due to unique properties of protein misfolding and oligomerization. Alpha-synuclein protein (α-Syn) is the predominant component of Lewy Bodies in Parkinson's disease (PD) and is a member of this class of proteins. Many α-Syn studies are limited by the inability to separate various monomeric, oligomeric, and fibrillar forms of the protein from heterogeneous mixtures. This Editorial Highlight summarizes the impact of a study published in the current issue of Journal of Neurochemistry, in which Lashuel and colleagues developed a simple, rapid centrifugation- and filter-based method for separating, isolating, and quantifying different forms of α-Syn. The researchers used electron microscopy, SDS-PAGE, circular dichroism, and protein assays to carefully validate the method and quantitate α-Syn yields and loss. The publication of this new method will not only aid in future studies of α-Syn, but will likely extend to other proteins that underlie a variety of neurodegenerative diseases. © 2020 International Society for Neurochemistry.This editorial perspective comments on the evidence that mental health is deteriorating among children and young people at the same time as the impact of poor mental health is more impairing. It discusses the methodological difficulties in detecting a 'true' change in prevalence. AMG PERK 44 supplier There are particular gaps in the evidence from low- and middle-income countries and also in relation to autism spectrum disorders. The evidence in high-income countries points to recent increases in anxiety, depression and self-harm in teenagers, particularly young women. We need more longitudinal data to disentangle the potential explanations for these changes. © 2020 Association for Child and Adolescent Mental Health.OBJECTIVES To assess the efficacy of self-collected vaginal samples compared with physician-collected cervical samples for the detection of HPVDNA. METHODS A hospital-based cross-sectional study was carried out among patients with newly diagnosed cervical cancer attending the Gynecologic Oncology Division, Department of Obstetrics and Gynecology and Radiation Oncology Department at Government Medical College, Kozhikode, Kerala between March 2017 and April 2019. Consenting patients collected their vaginal samples, followed by cervical sample collection by the clinician. The paired samples were transported at 4-8 °C to the laboratory. Amplification of LCR/E6/E7 regions of the HPV genome was done by polymerase chain reaction (PCR). The agreement level between paired samples was assessed by the Kappa index. RESULTS Among the 114 cervical cancer patients enrolled in the present cross-sectional study, the prevalence of HPV DNA was 78.1% (95% confidence interval [CI] 69.2%-85%) in cervical samples and 77.2% in vaginal samples (95% CI 68.
