Redox and catalase-like activities of four widely used carbon monoxide releasing molecules (CO-RMs).

The pathophysiological roles of the endogenous signaling molecule, carbon monoxide (CO), have been extensively studied and validated in cell culture and animal models. Further, evidence supporting the therapeutic effects of CO in various human diseases has been mounting over the last two decades. Along this line, there has been intensive interest in developing various delivery forms including CO gas, CO in solution, metal-carbonyl complexes widely known as CO-releasing molecules (CO-RMs), and organic CO prodrugs.

Self-perception of tongue tip constriction in alveolar fricatives produced by young women with and without normal tongue positioning.

Purpose: This study investigated the self-perception of 49 women, monolingual speakers of Brazilian Portuguese, about their tongue position for the alveolar articulation of the fricatives [s] and [z].

Methods: The video recording of speech samples of these 49 women (ages 18 to 28) were analyzed by three Speech-Language Pathologists. They were classified into two groups: Group 1 (G1, n=25), with no alterations in the tongue position during the production of [s] and [z], and Group 2 (G2, n=24), with alterations in the tongue position during the production of [s] and [z].

Adapting decarbonylation chemistry for the development of prodrugs capable of delivery of carbon monoxide utilizing sweeteners as carrier molecules.

Carbon monoxide as an endogenous signaling molecule exhibits pharmacological efficacy in various animal models of organ injury. To address the difficulty in using CO gas as a therapeutic agent for widespread applications, we are interested in developing CO prodrugs through bioreversible caging of CO in an organic compound. Specifically, we have explored the decarboxylation-decarbonylation chemistry of 1,2-dicarbonyl compounds.

Dietary compliance in a randomized double-blind infant feeding trial during infancy aiming at prevention of type 1 diabetes.

The international Trial to Reduce IDDM in the Genetically at Risk (TRIGR) tested the hypothesis whether extensively hydrolyzed casein-based versus regular cow's milk-based infant formula reduces the risk of type 1 diabetes. We describe dietary compliance in the trial in terms of study formula intake, feeding of nonrecommended foods, and serum cow's milk antibody concentration reflecting intake of cow's milk protein among 2,159 eligible newborn infants with a biological first-degree relative affected by type 1 diabetes and with HLA-conferred susceptibility to type 1 diabetes. The participating infants were introduced to the study formula feeding at the median age of 15 days with a median duration of study formula use of 63 days.

Pharmacophore-based screening of diamidine small molecule inhibitors for protein arginine methyltransferases.

Protein arginine methyltransferases (PRMTs) are essential epigenetic and post-translational regulators in eukaryotic organisms. Dysregulation of PRMTs is intimately related to multiple types of human diseases, particularly cancer. Based on the previously reported PRMT1 inhibitors bearing the diamidine pharmacophore, we performed virtual screening to identify additional amidine-associated structural analogs.

Accommodation-based interventions for individuals experiencing, or at risk of experiencing, homelessness.

Background: Globally, almost 1.6 billion individuals lack adequate housing. Many accommodation-based approaches have evolved across the globe to incorporate additional support and services beyond delivery of housing.

Effects of Emotion Dysregulation on Post-treatment Post-traumatic Stress Disorder and Depressive Symptoms Among Women Veterans With Military Sexual Trauma.

Military sexual trauma (MST), defined as sexual assault or repeated, threatening sexual harassment while in the military, is associated with increased risk of long-term mental and physical health problems, with the most common being symptoms of post-traumatic stress disorder (PTSD) and depression. In addition to PTSD and depression, MST is linked to difficulties in emotion regulation as well as poor treatment engagement. Thus, it is important to examine these correlates, and how they affect postintervention symptom reduction in this vulnerable population.

Guidance for producing a Campbell evidence and gap map.

Evidence and Gap Maps (EGMs) are a systematic evidence synthesis product which display the available evidence relevant to a specific research question. EGMs are produced following the same principles as a systematic reviews, that is: specify a PICOS, a comprehensive search, screening against explicit inclusion and exclusion criteria, and systematic coding, analysis and reporting. This paper provides guidance on producing EGMs for publication in Campbell Systematic Reviews.

Problem-oriented policing for reducing crime and disorder: An updated systematic review and meta-analysis.

Background: Herman Goldstein developed problem-oriented policing (POP) to focus police on more proactively addressing chronic problems, rather than using traditional reactive efforts. POP has been utilized to target a wide range of problems and has become commonly used in agencies across the United States and the world, although implementation is often uneven. POP interventions commonly use the SARA (scanning, analysis, response, assessment) model to identify problems, carefully analyze the conditions contributing to the problem, develop a tailored response to target these underlying factors, and evaluate outcome effectiveness.

Diabetes retinopathy and related health management in Asians versus whites using BRFSS 2005-2017 data.

Purpose: Asian Americans had high rate of type 2 diabetes and less risk for diabetes complications compared to white. The purpose of this study was to examine diabetic retinopathy and related healthcare management among Asian American adults with diabetes.

Materials And Method: Asian and white type 2 diabetes participants from 2005-2017 Behavioral Risk Factor Surveillance System (BRFSS) data were used to perform the analysis.

Patterns and trends of dual use of e-cigarettes and cigarettes among U.S. adults, 2015-2018.

Introduction: If dual use of cigarettes and e-cigarettes is a transition state to tobacco and nicotine use cessation, it may be a tolerable temporary condition. But, if a long-term behavior, dual use may increase tobacco harm to the population as a whole, and efforts should aim to reduce it as much as possible. To develop effective tobacco control policy, the changes in dual use of e-cigarettes and cigarettes need to be better understood.

Cardiomyocyte-Specific Prevents Inflammation in the Heart.

Background The SNRK (sucrose-nonfermenting-related kinase) enzyme is critical for cardiac function. However, the underlying cause for heart failure observed in cardiac conditional knockout mouse is unknown. Methods and Results Previously, 6-month adult mice knocked out for in cardiomyocytes (CMs) displayed left ventricular dysfunction.

Weighted Estimating Equations for Additive Hazards Models with Missing Covariates.

This paper presents simple weighted and fully augmented weighted estimators for the additive hazards model with missing covariates when they are missing at random. The additive hazards model estimates the difference in hazards and has an intuitive biological interpretation. The proposed weighted estimators for the additive hazards model use incomplete data nonparametrically and have close-form expressions.

HIV Infection and Incidence of Cardiovascular Diseases: An Analysis of a Large Healthcare Database.

Background People living with HIV ( PLWH ) experience higher risk of myocardial infarction ( MI ) and heart failure ( HF ) compared with uninfected individuals. Risk of other cardiovascular diseases ( CVD s) in PLWH has received less attention. Methods and Results We studied 19 798 PLWH and 59 302 age- and sex-matched uninfected individuals identified from the MarketScan Commercial and Medicare databases in the period 2009 to 2015.

Induction of immunity following vaccination with a chemically attenuated malaria vaccine correlates with persistent antigenic stimulation.

Objectives: Blood stage malaria parasites attenuated with seco-cyclopropyl pyrrolo indole (CPI) analogues induce robust immunity in mice to homologous and heterologous malaria parasites and are being considered for the development of a human vaccine. However, it is not understood how attenuated parasites induce immunity. We showed that following vaccination, parasite DNA persisted in blood for several months, raising the possibility that ongoing immune stimulation may be critical.

Estimation of a Latent Variable Regression Growth Curve Model for Individuals Cross-Classified by Clusters.

The cross-classified multiple membership latent variable regression (CCMM-LVR) model is a recent extension to the three-level latent variable regression (HM3-LVR) model which can be utilized for longitudinal data that contains individuals who changed clusters over time (for instance, student mobility across schools). The HM3-LVR model can include the initial status on growth effect as varying across those clusters and allows testing of more flexible hypotheses about the influence of initial status on growth and of factors that might impact that relationship, but only in the presence of pure clustering of participants within higher-level units. This Monte Carlo study was conducted to evaluate model estimation under a variety of conditions and to measure the impact of ignoring cross-classified data when estimating the incorrectly specified HM3-LVR model in a scenario in which true values for parameters are known.

pH-Sensitive metal-free carbon monoxide prodrugs with tunable and predictable release rates.

Carbon monoxide prodrugs with triggered release profiles are highly desirable for targeted CO delivery to minimize their untoward side-effects. Herein, we describe a series of pH-sensitive metal-free CO prodrugs which are stable under acidic conditions and yet begin to release CO in response to increases in pH with tunable and predictable release rates.
