The Influence of the CSU Robert Noyce Teacher Scholarship Program on Undergraduates\u27 Teaching Plans

The Robert Noyce Teacher Scholarship Program offers academic and financial support for students pursuing secondary teaching certificates in STEM fields. In return, students commit to teaching in high-need K-12 school districts. The Noyce Program has had uneven results in increasing the number of teachers in high needs schools. Large scale studies of its impact indicate the program is not likely to influence decisions to teach but may persuade participants to initially teach in high needs schools. To better understand the influence of the Noyce Program, we offer case studies of two Noyce scholarship recipients at different stages: (1) a former scholarship recipient who has graduated and is currently teaching, and (2) a second-year recipient who is currently pursuing a teaching certificate. This qualitative analysis provides insights that may have implications for optimizing scholarship programs for recruiting and retaining highly qualified STEM teachers

Early biomarker response and patient preferences to oral and intramuscular vitamin B12 substitution in primary care: a randomised parallel-group trial

Vitamin B12 (VB12) deficiency can be treated with oral high-dose substitution or intramuscular (i.m.) injection of VB12. Whenever alternative routes of administration exist, patient preferences should be considered when choosing the treatment. We aimed to assess outpatient preferences towards oral or IM VB12 substitution and confirm noninferiority of early biomarker response with oral treatment, in a typical primary care population.; Prospective randomised nonblinded parallel-group trial. Patients were recruited by their general practitioner and randomly assigned to oral or IM treatment. Group O-oral was given 28 tablets of 1000 µg cyanocobalamin in a monthly punch card fitted with an electronic monitoring system. Group I-IM received four, weekly injections of 1000 µg hydroxocobalamin. Blood samples were drawn before the first administration and after 1, 2 and 4 weeks of treatment, and analysed for VB12, holotranscobalamin (HoloTc), homocysteine (Hcy) and methylmalonic acid (MMA). For group O-oral, treatment adher-ence and percentage of days with 2 dosing events were calcu-lated. Before and after 28 days of treatment, patients were asked to fill in a questionnaire about their preference for the therapy options and associated factors.; Between November 2013 and December 2015, 37 patients (age: 49.5 ± 18.5 years; women: 60.5%) were recruited for oral (19) or IM (18) treatment. Baseline values with 95% confidence intervals for serum VB12, HoloTc, Hcy and MMA were 158 pmol/l [145-172], 49.0 pmol/l [40.4-57.5], 14.8 µmol/l [12.0-17.7] and 304 nmol/l [219-390], respective-ly, in group O-oral and 164 pmol/l [154-174], 50.1 pmol/l [38.7-61.6], 13.0 µmol/l [11.0-15.1] and 321 nmol/l [215-427], respectively, in group I-IM (not significant). After 1 month of treatment, levels of VB12 and HoloTc showed a significant increase compared with baseline (group O-oral: VB12 354 pmol/l [298-410] and HoloTc 156 pmol/l [116-196]; group I-IM: VB12 2796 pmol/l [1277-4314] and HoloTc 1269 pmol/l [103-2435]). Hcy and MMA levels showed a significant decrease compared with baseline (group O-oral: Hcy 13.8 µmol/l [10.7-16.8] and MMA 168 nmol/l [134-202]; group I-IM: Hcy 8.5 µmol/l [7.1-9.8] and MMA 156 nmol/l [121-190]). HoloTc and MMA levels were normalised in all patients after 4 weeks of treatment, whereas normalisation of VB12 and Hcy was reached by all patients in group I-IM only. Response of VB12, HoloTc and Hcy was more pronounced in group I-IM (p <0.01) and the primary hypothesis that oral VB12 treatment would be noninfe-rior to IM treatment was rejected. Average adherence to thera-py was 99.6 ± 1.1% and days with 2 dosing events reached 5.6%. Before randomisation, preference was in favour of oral treatment (45.9%, n = 17) over IM administration (21.6%, n = 8). Twelve patients (32.4%) had no preference. Nine (24.3%) patients changed their preference after treatment. Patients who obtained their preferred route of administration main-tained their preference in the case of oral treatment and changed their preference after IM treatment.; Differences in VB12 levels between groups were higher than expected. Therefore, noninferiority of oral treat-ment had to be rejected. However, normalisation of HoloTc and MMA was reached by all patients after a 1-month treatment period. The clinical benefit of the exaggerated biomarker re-sponse after IM treatment within a typical primary care popula-tion is questionable. Midterm biomarker effects and patient preferences should be considered when a therapeutic scheme is chosen. Initial rating in favour of either IM or oral therapy can change over time and justifies repeated re-evaluation of patient preferences. (ClinicalTrials.gov ID NCT01832129)

Characterization of two novel intronic OPA1 mutations resulting in aberrant pre-mRNA splicing.

BACKGROUND We report two novel splice region mutations in OPA1 in two unrelated families presenting with autosomal-dominant optic atrophy type 1 (ADOA1) (ADOA or Kjer type optic atrophy). Mutations in OPA1 encoding a mitochondrial inner membrane protein are a major cause of ADOA. METHODS We analyzed two unrelated families including four affected individuals clinically suspicious of ADOA. Standard ocular examinations were performed in affected individuals of both families. All coding exons, as well as exon-intron boundaries of the OPA1 gene were sequenced. In addition, multiplex ligation-dependent probe amplification (MLPA) was performed to uncover copy number variations in OPA1. mRNA processing was monitored using RT-PCR and subsequent cDNA analysis. RESULTS We report two novel splice region mutations in OPA1 in two unrelated individuals and their affected relatives, which were previously not described in the literature. In one family the heterozygous insertion and deletion c.[611-37_611-38insACTGGAGAATGTAAAGGGCTTT;611-6_611-16delCATATTTATCT] was found in all investigated family members leading to the activation of an intronic cryptic splice site. In the second family sequencing of OPA1 disclosed a de novo heterozygous deletion c.2012+4_2012+7delAGTA resulting in exon 18 and 19 skipping, which was not detected in healthy family members. CONCLUSION We identified two novel intronic mutations in OPA1 affecting the correct OPA1 pre-mRNA splicing, which was confirmed by OPA1 cDNA analysis. This study shows the importance of transcript analysis to determine the consequences of unclear intronic mutations in OPA1 in proximity to the intron-exon boundaries

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

The Influence of the Robert Noyce Teacher Scholarship Program on Undergraduates\u27 Teaching Plans

The Robert Noyce Teacher Scholarship Program offers academic and financial support for students pursuing secondary teaching certificates in STEM fields. In return, students commit to teaching in high-need K-12 school districts. In this completed research study, we examined factors that influence Noyce Scholars in their decisions about STEM as a major and teaching as a possible career. Through a thematic analysis of nine scholarship applications and a questionnaire, two participants at different stages in the program were selected to participate in a case study: (1) a former scholarship recipient who had graduated and was teaching, and (2) a second-year recipient enrolled in a teacher preparation program. Data were collected from these two participants through scholarship applications, questionnaires and a 45-minute interview. Findings indicated that informal or formal teaching experiences and socialization influences were highly motivating factors in participants’ decision to major in a STEM field and to pursue teaching as a career. The Noyce Scholarship was not a major factor in their decision to teach. These findings may have implications for optimizing scholarship programs to strengthen recruitment and retention in STEM teaching careers

Antiquitin Deficiency with Adolescent Onset Epilepsy: Molecular Diagnosis in a Mother of Affected Offsprings

Antiquitin deficiency is the most prevalent form of pyridoxine-dependent epilepsy. While most patients present with neonatal onset of therapy-resistant seizures, a few cases with late-onset during infancy have been described. Here, we describe the juvenile onset of epilepsy at the age of 17 years due to antiquitin deficiency in an Indian female with homozygosity for the most prevalent ALDH7A1 missense mutation, c.1279G > C; p.Glu427Gln in exon 14. The diagnosis was established along familial cosegregation analysis for an affected offspring, that had neonatal pyridoxine responsive seizures and had been found to be compound heterozygous for c.1279G > C; p.Glu427Gln in exon 14 and a nonsense mutation c.796C > T; p.Arg266* in exon 9. While seizures in the mother had been incompletely controlled by levetiracetam, she remained seizure-free on pyridoxine monotherapy, 200 mg/day. Her fourth pregnancy resulted in a female affected offspring, who was treated prospectively and never developed seizures with a normal outcome at age 2 years while on pyridoxine. This report illustrates that the phenotypic spectrum of antiquitin deficiency is still underestimated and that this treatable inborn error of metabolism has to be considered in case of therapy-resistant seizures even at older age. It furthermore supports prospective in utero treatment with pyridoxine in forthcoming pregnancies at risk

Investigating the Influence of the CSU Robert Noyce Teacher Scholarship Program on College Students\u27 Teaching Plans

The Robert Noyce Teacher Scholarship Program (CRAFT-STEM) at Columbus State University offers academic and financial support for students pursuing secondary teaching certificates in STEM fields. In return, students commit to teaching in high-need K-12 school districts in Georgia. Here we provide preliminary results regarding influences on students’ reasoning as they select teaching as a career, STEM as a content focus, and high-needs schools as future employment. With the support of a literature review, we plan to offer a preliminary qualitative analysis of case studies representing three Noyce scholarship recipients with a range of experiences: (1) a former scholarship recipient who has graduated and is currently teaching, (2) a second-year recipient who is currently pursuing their certificate, and (3) a recipient who subsequently decided not to pursue a secondary teaching certificate. Our goal is to offer insight to University STEM Professors on strengthening recruitment and retention in their areas of interest
