Visible-Light-Driven Triplet Sensitization of Polycyclic Aromatic Hydrocarbons Using Thionated Perinones.

Metal-free chromophores that efficiently generate triplet excited states represent promising alternatives with respect to transition metal-containing photosensitizers, such as those featuring metal-to-ligand charge transfer excited states. However, such molecular constructs have remained underexplored due to the unclear relationship(s) between molecular structure and efficient/rapid intersystem crossing. In this regard, we present a series of three thionated perinone chromophores serving as a newly conceived class of heavy metal-free triplet photosensitizers.

Cellular and Clinical Analyses of Autologous Bone Marrow Aspirate Injectate for Knee Osteoarthritis: A Pilot Study.

Introduction: Knee osteoarthritis (OA) is characterized by pain and functional deficits. Common conservative strategies include medications, physical therapy, and intra-articular injections. Recently, treatment using autologous cell injections has increased.

Energy Migration Processes in Re(I) MLCT Complexes Featuring a Chromophoric Ancillary Ligand.

We present the synthesis, structural characterization, electronic structure calculations, and ultrafast and supra-nanosecond photophysical properties of a series of five Re(I) bichromophores exhibiting metal to ligand charge transfer (MLCT) excited states based on the general formula -[Re(NN)(CO)(PNI-py)]PF where PNI-py is 4-piperidinyl-1,8-naphthalimidepyridine and NN is a diimine ligand (-), along with their corresponding model chromophores where 4-ethylpyridine was substituted for PNI-py (-). The diimine ligands used include 1,10-phenanthroline (phen, ), 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (bcp, ), 4,4'-di--butyl-2,2'-bipyridine (dtbb, ), 4,4'-diethyl ester-2,2'-bipyridine (deeb, ), and 2,2'-biquinoline (biq, ). In these metal-organic bichromophores, structural modification of the diimine ligand resulted in substantial changes to the observed energy transfer efficiencies between the two chromophores as a result of the variation in MLCT excited-state energies.

Development of a Group-Based Community Health Worker Intervention to Increase Colorectal Cancer Screening Among Latinos.

Introduction: Latinos are at higher risk of colorectal cancer (CRC) mortality than non-Hispanic Whites due, in part, to disparities in cancer screening. There is a need to evaluate community-based CRC interventions as they may reach underinsured communities and those at highest risk for CRC. This article describes the development of a group-based CRC intervention ().

Engaging Community Networks to Improve Depression Services: A Cluster-Randomized Trial of a Community Engagement and Planning Intervention.

This paper explores the effects of a group-randomized controlled trial, Community Partners in Care (CPIC), on the development of interagency networks for collaborative depression care improvement between a community engagement and planning (CEP) intervention and a resources for services (RS) intervention that provided the same content solely via technical assistance to individual programs. Both interventions consisted of a diverse set of service agencies, including health, mental health, substance abuse treatment, social services, and community-trusted organizations such as churches and parks and recreation centers. Participants in the community councils for the CEP intervention reflected a range of agency leaders, staff, and other stakeholders.

Hippocampal Subfield Volumes in Middle-Aged Adults at Risk of Dementia.

Background: Alzheimer's disease (AD) begins decades before the onset of dementia. There is a need to investigate biomarkers of early AD for use in clinical trials and to facilitate early intervention.

Objective: We aimed to determine whether changes in hippocampal subfield volumes in healthy middle-aged adults were associated with risk of future dementia.

Improving the implementation and sustainment of evidence-based practices in community mental health organizations: a study protocol for a matched-pair cluster randomized pilot study of the Collaborative Organizational Approach to Selecting and Tailoring Implementation Strategies (COAST-IS).

Background: Implementing and sustaining evidence-based programs with fidelity may require multiple implementation strategies tailored to address multi-level, context-specific barriers and facilitators. Ideally, selecting and tailoring implementation strategies should be guided by theory, evidence, and input from relevant stakeholders; however, methods to guide the selection and tailoring of strategies are not well-developed. There is a need for more rigorous methods for assessing and prioritizing implementation determinants (barriers and facilitators) and linking implementation strategies to determinants.

Distinct spread of DNA and RNA viruses among mammals amid prominent role of domestic species.

Aim: Emerging infectious diseases arising from pathogen spillover from mammals to humans constitute a substantial health threat. Tracing virus origin and predicting the most likely host species for future spillover events are major objectives in One Health disciplines.We assessed patterns of virus sharing among a large diversity of mammals, including humans and domestic species.

Whipworms of south-east Asian rodents are distinct from Trichuris muris.

The whipworm Trichuris muris is known to be associated with various rodent species in the northern hemisphere, but the species identity of whipworm infecting rodents in the Oriental region remains largely unknown. We collected Trichuris of Muridae rodents in mainland and insular Southeast Asia between 2008 and 2015 and used molecular and morphological approaches to identify the systematic position of new specimens. We discovered two new species that were clearly distinct from T.

Volumetric alterations in the hippocampal subfields of subjects at increased risk of dementia.

The hippocampus is one of the first regions to demonstrate atrophy during the prodromal stage of Alzheimer's disease. Volumetric analysis of its individual subfields could provide biomarkers with higher sensitivity than whole hippocampal volume during an earlier disease stage. We quantified the hippocampal subfields volume in a large cohort comprising healthy participants (aged 40-59) with dementia family history (FH) and controls (without FH), examined at 2 time points across 2 years.

Contributions of Voice and Nonverbal Communication to Perceived Masculinity-Femininity for Cisgender and Transgender Communicators.

Purpose The purpose of this study was twofold: (a) to identify a set of communication-based predictors (including both acoustic and gestural variables) of masculinity-femininity ratings and (b) to explore differences in ratings between audio and audiovisual presentation modes for transgender and cisgender communicators. Method The voices and gestures of a group of cisgender men and women ( = 10 of each) and transgender women ( = 20) communicators were recorded while they recounted the story of a cartoon using acoustic and motion capture recording systems. A total of 17 acoustic and gestural variables were measured from these recordings.

The experience of living after ECT: a qualitative meta-synthesis.

Background: Electroconvulsive therapy (ECT) is a controversial treatment. Research has predominantly focused on clinician assessment of short-term efficacy and, occasionally, on participant experiences of the treatment itself. While service user accounts of the long-term impacts of ECT are reported, they are dispersed throughout the literature and typically tangential to studie's main foci.

Association between Clostridioides difficile infection and multidrug-resistant organism colonization or infection among hospitalized adults: A case-control study.

Using an ambidirectional case-control study, we found that the odds of Clostridioides difficile infection (CDI) were 3.38 (P = .01) times higher for patients with multidrug-resistant organism (MDRO) colonization compared to those without.

Training with cognitive load improves performance under similar conditions in a real surgical task.

Background: Enhancing cognitive load while performing a bimanual surgical task affects performance. Whether repeated training under this condition could benefit performance in an operating room was tested using a virtual reality simulator with cognitive load applied through two-digit math multiplication questions.

Method: 11 subjects were randomized to Control, VR and VR + CL groups.

The use of cells from ANPEP knockout pigs to evaluate the role of aminopeptidase N (APN) as a receptor for porcine deltacoronavirus (PDCoV).

The coronaviruses, porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV), and porcine deltacoronavirus (PDCoV) represent important sources of neonatal diarrhea on pig farms. The requirement for aminopeptidase N (APN) as a receptor for TGEV, but not for PEDV, is well established. In this study, the biological relevance of APN as a receptor for PDCoV was tested by using CRISPR/Cas9 to knockout the APN gene, ANPEP, in pigs.

Improving childhood vaccination coverage rates: the case of fourth dose of DTaP.

Based on the most recently available national data, vaccination coverage for the combined seven-vaccine series recommended by age 24 months remains substantially below the Healthy People 2020 target of 80%. One focus for improvement is the lack of timely administration of the fourth dose of DTaP vaccine. Based on the perspective of state and local immunization program managers, key strategies include tracking immunization patterns through immunization information systems and other data sources, working with health-care providers to address challenges to timely vaccination, and developing partnerships with daycares, payers, and health systems.

Models of spatiotemporal variation in rabbit abundance reveal management hot spots for an invasive species.

The European rabbit (Oryctolagus cuniculus) is a notorious economic and environmental pest species in its invasive range. To better understand the population and range dynamics of this species, 41 yr of abundance data have been collected from 116 unique sites across a broad range of climatic and environmental conditions in Australia. We analyzed this time series of abundance data to determine whether interannual variation in climatic conditions can be used to map historic, contemporary, and potential future fluctuations in rabbit abundance from regional to continental scales.

Two-Step Deep Learning for Estimating Human Sleep Pose Occluded by Bed Covers.

In this study, a novel sleep pose identification method has been proposed for classifying 12 different sleep postures using a two-step deep learning process. For this purpose, transfer learning as an initial stage retrains a well-known CNN network (VGG-19) to categorise the data into four main pose classes, namely: supine, left, right, and prone. According to the decision made by VGG-19, subsets of the image data are next passed to one of four dedicated sub-class CNNs.

Clinical state tracking in serious mental illness through computational analysis of speech.

Individuals with serious mental illness experience changes in their clinical states over time that are difficult to assess and that result in increased disease burden and care utilization. It is not known if features derived from speech can serve as a transdiagnostic marker of these clinical states. This study evaluates the feasibility of collecting speech samples from people with serious mental illness and explores the potential utility for tracking changes in clinical state over time.

Outcomes of two quality improvement implementation interventions for depression services in adults with substance use problems.

: Comorbid depression and substance use disorders (SUDs) are associated with poor health and social outcomes disproportionately affecting under-resourced communities.: To test the hypothesis that a coalition approach to collaborative care (CC) for depression would improve outcomes of hazardous drinking and behavioral health hospitalizations, relative to technical assistance, for individuals with comorbid substance use problems. Substance use problems were defined by meeting criteria for DSM-IV substance abuse or dependence, hazardous drinking by AUDIT-C, or treatment in a SUD program within the prior 6 months.

Expanding the Natural Products Heterologous Expression Repertoire in the Model Cyanobacterium sp. Strain PCC 7120: Production of Pendolmycin and Teleocidin B-4.

Cyanobacteria are prolific producers of natural products, and genome mining has shown that many orphan biosynthetic gene clusters can be found in sequenced cyanobacterial genomes. New tools and methodologies are required to investigate these biosynthetic gene clusters, and here we present the use of sp. strain PCC 7120 as a host for combinatorial biosynthesis of natural products using the indolactam natural products (lyngbyatoxin A, pendolmycin, and teleocidin B-4) as a test case.
