The findings of the present study can provide strong support to the fundamental understanding and applications of ARHCRs for water disinfection.TiO2 catalyst was synthesized in the presence of ultrasound (ultrasonic horn at 20 kHz frequency and 70% duty cycle) at different power (80 W to 120 W) and durations as well as surfactant concentration with an objective of establishing best conditions for achieving lowest particle size of the photocatalyst. Detailed characterization in terms of crystal phase, crystallinity, functional groups and morphology of the photocatalyst has been performed using SEM, XRD and FTIR analysis. click here It was demonstrated that sonication significantly reduced the particle size with high degree of sphericity and homogeneity as compared to conventionally synthesized TiO2 with similar crystallinity in both cases. The catalytic performance was subsequently evaluated for the deep desulfurization of thiophene. Different desulfurization approaches including individual US (ultrasonic horn at 20 kHz frequency, 110 W power and 70% duty cycle) and UV irradiations, US/UV, US/UV/H2O2, US/UV/TiO2 and US/UV/H2O2/TiO2 were applied to evaluate the catalytic activity. The best approach was demonstrated as US/UV/H2O2/TiO2 and also activity of catalyst synthesized using ultrasound was much better compared to conventionally synthesized catalyst. The studies related to different model solvents demonstrated lowest reactivity for toluene whereas n-hexane and n-octane resulted in complete desulfurization in 60 min and 50 min treatment respectively. The desulfurization followed pseudo first order reaction kinetics irrespective of the solvent used. Overall the work clearly demonstrated the efficacy of ultrasound in improving the catalyst synthesis as well as desulfurization of thiophene.Neuronal ceroid lipofuscinosis type 2 (CLN2 disease) is an autosomal recessive neurodegenerative disorder generally with onset at 2 to 4 years of age and characterized by seizures, loss of vision, progressive motor and mental decline, and premature death. CLN2 disease is caused by loss-of-function mutations in the tripeptidyl peptidase 1 (TPP1) gene leading to deficiency in TPP1 enzyme activity. Approximately 60% of patients have one of two pathogenic variants (c.509-1G > C or c.622C > T [p.(Arg208*)]). In order to generate a human stem cell model of CLN2 disease, we used CRISPR/Cas9-mediated knock-in technology to introduce these mutations in a homozygous state into H9 human embryonic stem cells. Heterozygous lines of the c.622C > T (p.(Arg208*)) mutation were also generated, which included a heterozygous mutant with a wild-type allele and different compound heterozygous coding mutants resulting from indels on one allele. We describe the methodology that led to the generation of the lines and provide data on the initial validation and characterization of these CLN2 disease models. Notably, both mutant lines (c.509-1G > C and c.622C > T [p.(Arg208*)]) in the homozygous state were shown to have reduced or absent protein, respectively, and deficiency of TPP1 enzyme activity. These models, which we have made available for wide-spread sharing, will be useful for future studies of molecular and cellular mechanisms underlying CLN2 disease and for therapeutic development.Skin fibroblasts derived from a 71-year-old healthy woman were reprogrammed into induced pluripotent stem cells (iPSCs) by the transduction of retroviruses expressing OCT4, SOX2, KLF4 and c-MYC, respectively. The generated iPSCs maintained a normal karyotype and expressed various pluripotency markers. Moreover, they could be induced to form embryoid bodies in vitro and teratomas in vivo, indicating the full capacity of differentiating into three germ layers. This iPSC line could be differentiated into multiple cell subtypes for cellular modeling and drug discovery.Child sexual abuse (CSA) is common, severe, and substantively contributes to the global burden of disease through its impact on physical, mental, and behavioral health problems. While CSA is preventable through non-justice system response efforts, the vast majority of resources support criminal justice efforts to identify, prosecute, punish and monitor offenders after CSA has already occurred. Policy makers have not supported CSA prevention efforts in part because the public does not view CSA as a preventable public health problem. Here, we describe a program of research to be conducted to bridge the gaps between expert and public opinion about CSA as a preventable public health problem. We propose such research use a three-step approach to alter the way experts communicate about CSA to increase audiences' understanding of CSA as preventable. The three steps are 1) identify consensus expert and public perspectives about CSA and the differences between these perspectives; 2) develop and test communication strategies to align public with expert perspectives; and 3) broadly disseminate validated communication strategies. Through this approach, we seek to develop and disseminate an informed communications strategy that effectively and accurately translates the science of CSA prevention to the public and the media.
Research has indicated an association between child abuse and adolescent suicide. Little population-based information exists, however, about the nature of maltreatment experiences or interactions with the child protection system (CPS).

To examine child maltreatment characteristics and system-level responses associated with risk of adolescent suicide.

Linked vital death records and CPS records were used to identify the population of adolescents who died by suicide in California between 2010 and 2017 and who had a history of at least one report to CPS prior to death.

A case control design was used, with cases defined as a suicide of an adolescent with a history of CPS involvement. Using CPS records, living controls were then matched to cases based on year of birth, sex, race and ethnicity, and age of first child maltreatment allegation. A conditional logistic regression model was used to estimate the adjusted odds of adolescent suicide across various CPS and maltreatment characteristics.

Recent CPS involvement, allegations of physical abuse, and allegations of sexual abuse emerged as significant risk factors for death by suicide.
