Disulfide Tethering to Map Small Molecule Binding Sites Transcriptome-wide.

We report the development of Tether-seq, a transcriptome-wide screen to probe RNA-small molecule interactions using disulfide tethering. This technique uses sU metabolic labeling to provide sites for reversible and covalent attachment of small molecule disulfides to the transcriptome. By screening under reducing conditions, we identify interactions that are stabilized by binding over those driven by the reactivity of the RNA sites.

Continuity Strategies for Long-Stay PICU Patients: Consensus Statements From the Lucile Packard Foundation PICU Continuity Panel.

Objectives: To develop consensus statements on continuity strategies using primary intensivists, primary nurses, and recurring multidisciplinary team meetings for long-stay patients (LSPs) in PICUs.

Participants: The multidisciplinary Lucile Packard Foundation PICU Continuity Panel comprising parents of children who had prolonged PICU stays and experts in several specialties/professions that care for children with medical complexity in and out of PICUs.

Design/methods: We used modified RAND Delphi methodology, with a comprehensive literature review, Delphi surveys, and a conference, to reach consensus.

Group Concept Mapping Conceptualizes High-Quality Care for Long-Stay Pediatric Intensive Care Unit Patients and Families.

Objective: To describe and conceptualize high-quality care for long-stay pediatric intensive care unit (PICU) patients using group concept mapping (GCM).

Study Design: We convened an expert panel to elucidate domains of high-quality care for this growing patient population for which transitory care models fail to meet their needs. Thirty-one healthcare professionals and 7 parents of patients with previous prolonged PICU hospitalizations comprised a diverse, interprofessional multidisciplinary panel.

Immune markers are associated with cognitive performance in a multiethnic cohort: The Northern Manhattan Study.

Objective: To determine whether immune protein panels add significant information to correlates of cognition.

Background: Immune mechanisms in vascular cognitive aging are incompletely characterized.

Design/methods: A subsample of the prospective Northern Manhattan Study underwent detailed neuropsychological testing.

Race/Ethnic Disparities in Mild Cognitive Impairment and Dementia: The Northern Manhattan Study.

Background: Variability in dementia rates across racial and ethnic groups has been estimated at 60%. Studies suggest disparities in Caribbean Hispanic and Black populations, but community-based data are limited.

Objective: Estimate the prevalence of mild cognitive impairment (MCI) and dementia in the racially and ethnically diverse community-based Northern Manhattan Study cohort and examine sociodemographic, vascular risk factor, and brain imaging correlates.

Parallel Discovery Strategies Provide a Basis for Riboswitch Ligand Design.

Riboswitches are mRNA domains that make gene-regulatory decisions upon binding their cognate ligands. Bacterial riboswitches that specifically recognize 5-aminoimidazole-4-carboxamide riboside 5'-monophosphate (ZMP) and 5'-triphosphate (ZTP) regulate genes involved in folate and purine metabolism. Now, we have developed synthetic ligands targeting ZTP riboswitches by replacing the sugar-phosphate moiety of ZMP with various functional groups, including simple heterocycles.

Employing a ZTP Riboswitch to Detect Bacterial Folate Biosynthesis Inhibitors in a Small Molecule High-Throughput Screen.

Various riboswitch classes are being discovered that precisely monitor the status of important biological processes, including metabolic pathway function, signaling for physiological adaptations, and responses to toxic agents. Biochemical components for some of these processes might make excellent targets for the development of novel antibacterial molecules, which can be broadly sought by using phenotypic drug discovery (PDD) methods. However, PDD data do not normally provide clues regarding the target for each hit compound.

Synthetic ligands for PreQ riboswitches provide structural and mechanistic insights into targeting RNA tertiary structure.

Riboswitches are naturally occurring RNA aptamers that regulate gene expression by binding to specific small molecules. Riboswitches control the expression of essential bacterial genes and are important models for RNA-small molecule recognition. Here, we report the discovery of a class of synthetic small molecules that bind to PreQ riboswitch aptamers.

Measuring RNA-Ligand Interactions with Microscale Thermophoresis.

In recent years, there has been dramatic growth in the study of RNA. RNA has gone from being known as an intermediate in the central dogma of molecular biology to a molecule with a large diversity of structure and function that is involved in all aspects of biology. As new functions are rapidly discovered, it has become clear that there is a need for RNA-targeting small molecule probes to investigate RNA biology and clarify the potential for therapeutics based on RNA-small molecule interactions.

Discovery of Inhibitors of MicroRNA-21 Processing Using Small Molecule Microarrays.

The identification of small molecules that bind to and perturb the function of microRNAs is an attractive approach for the treatment for microRNA-associated pathologies. However, there are only a few small molecules known to interact directly with microRNAs. Here, we report the use of a small molecule microarray (SMM) screening approach to identify low molecular weight compounds that directly bind to a pre-miR-21 hairpin.

The Emerging Role of RNA as a Therapeutic Target for Small Molecules.

Recent advances in understanding different RNAs and unique features of their biology have revealed a wealth of information. However, approaches to identify small molecules that target these newly discovered regulatory elements have been lacking. The application of new biochemical screening and design-based technologies, coupled with a resurgence of interest in phenotypic screening, has resulted in several compelling successes in targeting RNA.

Mothers' and fathers' differential expectancies and behaviors: parent x child gender effects.

In 3 studies using 6 subscales, the authors investigated (a) others' parenting expectancies for mothers and fathers and (b) parents' reports of the frequency of their parenting behaviors with their 3- to 6-year-old sons and daughters. Mothers rated higher for physical care and emotional support than did fathers, and mothers reported engaging in the parenting behaviors assessed more frequently than did fathers across subscales. In each study, the authors obtained Parent x Child Gender interactions only for personal-interaction parenting (e.

Adult-onset Alexander disease with progressive ataxia and palatal tremor.

A novel glial fibrillary acidic protein (GFAP) mutation, Y257C, is reported in a patient with adult-onset Alexander disease. This is the oldest reported case with confirmation of a GFAP mutation. Onset was late in the sixth decade.
