Late-childhood foundational cognitive skills predict educational outcomes through adolescence and into young adulthood: evidence from Ethiopia and Peru.

We estimate associations between foundational cognitive skills (inhibitory control, working memory, long-term memory, and implicit learning) measured at age 12 and educational outcomes measured at ages 15 and 19-20 in Ethiopia and Peru, using the Young Lives data. The estimates adjust for rich sets of controls and include measurements of children's baseline abilities. For a subset of the outcomes, we exploit within-household variation.

Functional delineation of the luminal epithelial microenvironment in breast using cell-based screening in combinatorial microenvironments.

Microenvironment signals are potent determinants of cell fate and arbiters of tissue homeostasis, however understanding how different microenvironment factors coordinately regulate cellular phenotype has been experimentally challenging. Here we used a high-throughput microenvironment microarray comprised of 2640 unique pairwise signals to identify factors that support proliferation and maintenance of primary human mammary luminal epithelial cells. Multiple microenvironment factors that modulated luminal cell number were identified, including: HGF, NRG1, BMP2, CXCL1, TGFB1, FGF2, PDGFB, RANKL, WNT3A, SPP1, HA, VTN, and OMD.

Subretinal deposits in young patients treated with voretigene neparvovec-rzyl for RPE65-mediated retinal dystrophy.

We report a series of three young patients (ages: 22 months, 2 years, and 5 years) who developed subretinal deposits at post-operative week one following subretinal voretigene neparvovec-rzyl treatment for RPE65-mediated retinal dystrophy. In the 5-year-old, subretinal deposits were also observed in the inferior periphery of both eyes. All three patients experienced improved visual function with treatment, and both the macular and inferior subretinal deposits have improved or resolved over the follow-up period.

Solvent-free synthesis of 3,5-isoxazoles 1,3-dipolar cycloaddition of terminal alkynes and hydroxyimidoyl chlorides over Cu/AlO surface under ball-milling conditions.

Scalable, solvent-free synthesis of 3,5-isoxazoles under ball-milling conditions has been developed. The proposed methodology allows the synthesis of 3,5-isoxazoles in moderate to excellent yields from terminal alkynes and hydroxyimidoyl chlorides, using a recyclable Cu/AlO nanocomposite catalyst. Furthermore, the proposed conditions are reproducible to a 1.

Evidence for accelerated aging in mammary epithelia of women carrying germline or mutations.

During aging in the human mammary gland, luminal epithelial cells lose lineage fidelity by expressing markers normally expressed in myoepithelial cells. We hypothesize that loss of lineage fidelity is a general manifestation of epithelia that are susceptible to cancer initiation. In the present study, we show that histologically normal breast tissue from younger women who are susceptible to breast cancer, as a result of harboring a germline mutation in , or genes, exhibits hallmarks of accelerated aging.

Deep proteome profiling of human mammary epithelia at lineage and age resolution.

Age is the major risk factor in most carcinomas, yet little is known about how proteomes change with age in any human epithelium. We present comprehensive proteomes comprised of >9,000 total proteins and >15,000 phosphopeptides from normal primary human mammary epithelia at lineage resolution from ten women ranging in age from 19 to 68 years. Data were quality controlled and results were biologically validated with cell-based assays.

Incidence of Proliferative Diabetic Retinopathy and Other Neovascular Sequelae at 5 Years Following Diagnosis of Type 2 Diabetes.

Objective: To determine the incidence and risk factors for developing proliferative diabetic retinopathy (PDR), tractional retinal detachment (TRD), and neovascular glaucoma (NVG) at 5 years after the initial diagnosis of type 2 diabetes.

Research Design And Methods: Insured patients aged ≥18 years with newly diagnosed type 2 diabetes and 5 years of continuous enrollment were identified from a nationwide commercial claims database containing data from 2007 to 2015. The incidences of PDR, TRD, and NVG were computed at 5 years following the index diagnosis of type 2 diabetes.

Changes in Immune Cell Types with Age in Breast are Consistent with a Decline in Immune Surveillance and Increased Immunosuppression.

A majority of breast cancers (BC) are age-related and we seek to determine what cellular and molecular changes occur in breast tissue with age that make women more susceptible to cancer initiation. Immune-epithelial cell interactions are important during mammary gland development and the immune system plays an important role in BC progression. The composition of human immune cell populations is known to change in peripheral blood with age and in breast tissue during BC progression.

Breast-Specific Molecular Clocks Comprised of Expression and Promoter Methylation Identify Individuals Susceptible to Cancer Initiation.

A robust breast cancer prevention strategy requires risk assessment biomarkers for early detection. We show that expression of , a transcription factor critical for normal mammary development, is downregulated in mammary luminal epithelia with age. DNA methylation of the promoter is negatively correlated with expression in an age-dependent manner.

Methods: A MEDLINE literature search for cases of orbital schwannomas was performed using the PubMed search tool using the search terms "orbital schwannoma" and "orbital neurilemmoma." Papers were included if they were peer-reviewed, published in English, discussed management, and included the search terms.

The Protective Effect of Estrogen Against Radiation Cataractogenesis is Dependent Upon the Type of Radiation.

Astronauts participating in prolonged space missions constitute a population of individuals who are at an increased risk for cataractogenesis due to exposure to densely ionizing charged particles. Using a rat model, we have previously shown that after irradiation of eyes with either low-linear energy transfer (LET) 60Co γ rays or high-LET 56Fe particles, the rate of progression of anterior and posterior subcapsular cataracts was significantly greater in ovariectomized females implanted with 17-β-estradiol (E2) compared to ovariectomized or intact rats. However, our additional low-LET studies indicated that cataractogenesis may be a modifiable late effect, since we have shown that the modulation of cataractogenesis is dependent upon the timing of administration of E2.

In Florida, injured children can receive emergent care at one of three types of state-approved trauma centers (TCs). A Level 1 combined adult/pediatric TC (L1, A + P), a Level 2 TC with an associated pediatric hospital (L2 + PH) or a pediatric TC at a pediatric hospital (PTH). This study aims to compare the mortality outcomes between Florida L1, A + Ps, to L2 + PHs, and PTHs.

Health Literacy for an Aging Population: Evaluating Online Tools for the Homebound Over Age 65.

The number of seniors over age 65 aging at home is increasing. They require usable health information to make informed decisions to maintain health and independence. This study partnered with Meals On Wheels, Inc.

Text Messaging Interventions on Cancer Screening Rates: A Systematic Review.

Background: Despite high-quality evidence demonstrating that screening reduces mortality from breast, cervical, colorectal, and lung cancers, a substantial portion of the population remains inadequately screened. There is a critical need to identify interventions that increase the uptake and adoption of evidence-based screening guidelines for preventable cancers at the community practice level. Text messaging (short message service, SMS) has been effective in promoting behavioral change in various clinical settings, but the overall impact and reach of text messaging interventions on cancer screening are unknown.

Identification of Multiple Proteins Coupling Transcriptional Gene Silencing to Genome Stability in Arabidopsis thaliana.

Eukaryotic genomes are regulated by epigenetic marks that act to modulate transcriptional control as well as to regulate DNA replication and repair. In Arabidopsis thaliana, mutation of the ATXR5 and ATXR6 histone methyltransferases causes reduction in histone H3 lysine 27 monomethylation, transcriptional upregulation of transposons, and a genome instability defect in which there is an accumulation of excess DNA corresponding to pericentromeric heterochromatin. We designed a forward genetic screen to identify suppressors of the atxr5/6 phenotype that uncovered loss-of-function mutations in two components of the TREX-2 complex (AtTHP1, AtSAC3B), a SUMO-interacting E3 ubiquitin ligase (AtSTUbL2) and a methyl-binding domain protein (AtMBD9).

Tiling Assembly: a new tool for reference annotation-independent transcript assembly and novel gene identification by RNA-sequencing.

Annotation of the rice (Oryza sativa) genome has evolved significantly since release of its draft sequence, but it is far from complete. Several published transcript assembly programmes were tested on RNA-sequencing (RNA-seq) data to determine their effectiveness in identifying novel genes to improve the rice genome annotation. Cufflinks, a popular assembly software, did not identify all transcripts suggested by the RNA-seq data.

Improving Outcomes by Implementing a Pressure Ulcer Prevention Program (PUPP): Going beyond the Basics.

A multidisciplinary process improvement program was initiated at the University of Miami Hospital (UMH) in 2009 to identify the prevalence of hospital-acquired pressure ulcers (HAPU) at the institution and to implement interventions to reduce the incidence of HAPU. This deliberate and thoughtful committee-driven process evaluated care, monitored results, and designed evidence-based strategic initiatives to manage and reduce the rate of HAPU. As a result all inpatient beds were replaced with support surfaces, updated care delivery protocols were created, and monitored, turning schedules were addressed, and a wound, ostomy, and continence (WOC) nurse and support staff were hired.

Structural basis of substrate specificity and selectivity of murine cytosolic 5'-nucleotidase III.

Cytosolic 5'-nucleotidase III (cN-III) is responsible for selective degradation of pyrimidine 5'-monoribonucleotides during maturation of reticulocytes to erythrocytes. The lack of this enzymatic activity due to genetic aberrations or lead poisoning results in a mild to moderate nonspherocytic hemolytic anemia. In affected individuals, pyrimidine nucleotides as well as their precursor polymers and their off-path metabolites accumulate in erythrocytes, interfering with their proper function in ways that are not yet fully understood.
