Community Violence in Childhood

Experiencing violence in childhood is an all too common occurrence, especially in sexual and gender minority communities. It can be hard to dictate predictors of these such occurrences, which is the focus of our study. A survey regarding many different experiences members of these communities can have was taken by 1316 people via Reddit. Out of these participants, 309 reported experiencing some form of violence in their childhood. Among the demographic information taken for the survey, none had a significant correlation besides education. Although this factor did have statistical significance, there is no logical explanation as education can be continued after childhood, therefore it isn’t necessarily classified as a predictor. There was a larger amount of reported violence in childhood among gender minorities than sexual minorities, however. This increase can be due to many factors, the main one potentially being the difference in how a person may present their sexuality versus how they may present their gender. These findings help begin the start of the research towards why these violent experiences can be common among these communities and preventative measures that can be taken to put an end to it

Microwave Crash Sensor for Automobiles

International Telemetering Conference Proceedings / September 27-29, 1971 / Washington Hilton Hotel, Washington, D.C.A prototype microwave radar anticipatory crash sensor for automotive applications is described. This system is for prospective use in conjunction with passive occupant restraints--protective devices that require no action on the part of the occupant to insure their effectiveness. Appropriate antenna configuration and circuitry permit position, velocity, and size discrimination of the target in a simple manner. Results of field tests are discussed, including the manner in which system parameters and target characteristics relate to the tradeoff between false alarm rate, miss rate, and system complexity.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.

PKCδ mediates mineralocorticoid receptor activation by angiotensin ii to modulate smooth muscle cell function

Angiotensin II (AngII) and the mineralocorticoid receptor (MR) ligand aldosterone both contribute to cardiovascular disorders, including hypertension and adverse vascular remodeling. We previously demonstrated that AngII activates MR-mediated gene transcription in human vascular smooth muscle cells (SMCs), yet the mechanism and the impact on SMC function are unknown. Using an MR-responsive element-driven transcriptional reporter assay, we confirm that AngII induces MR transcriptional activity in vascular SMCs and endothelial cells, but not in Cos1 or human embryonic kidney-293 cells. AngII activation of MR was blocked by the MR antagonist spironolactone or eplerenone and the protein kinase C-δ (PKCδ) inhibitor rottlerin, implicating both in the mechanism. Similarly, small interfering RNA knockdown of PKCδ in SMCs prevented AngII-mediated MR activation, whereas knocking down of MR blocked both aldosterone- and AngII-induced MR function. Coimmunoprecipitation studies reveal that endogenous MR and PKCδ form a complex in SMCs that is enhanced by AngII treatment in association with increased serine phosphorylation of the MR N terminus. AngII increased mRNA expression of the SMC-MR target gene, FKBP51, via an MR-responsive element in intron 5 of the FKBP51 gene. The impact of AngII on FKBP51 reporter activity and gene expression in SMCs was inhibited by spironolactone and rottlerin. Finally, the AngII-induced increase in SMC number was also blocked by the MR antagonist spironolactone and the PKCδ inhibitor rottlerin. These data demonstrate that AngII activates MR transcriptional regulatory activity, target gene regulation, and SMC proliferation in a PKCδ-dependent manner. This new mechanism may contribute to synergy between MR and AngII in driving SMC dysfunction and to the cardiovascular benefits of MR and AngII receptor blockade in humans160921012114FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP2014/26192-6This work was supported by National Institutes of Health Grants HL095590 and HL119290 (to I.Z.J.), American Heart Association Grants EIA18290005 (to I.Z.J.) and 11POST5390010 (to A.P.M.), and by São Paulo Research Foundation (FAPESP) Grant 2014/26192-6 to (A.P.D.
