Magnesium sulphate for women at risk of preterm birth for neuroprotection of the fetus
No full textCopyright © 2009 The Cochrane Collaboration. Published by John Wiley & Sons, Ltd.BackgroundEpidemiological and basic science evidence suggests that magnesium sulphate before birth may be neuroprotective for the fetus.ObjectivesTo assess the effectiveness and safety of magnesium sulphate as a neuroprotective agent when given to women considered at risk of preterm birth.Search strategyWe searched the Cochrane Pregnancy and Childbirth Group's Trials Register (October 2006), CENTRAL (The Cochrane Library 2006, Issue 3), MEDLINE (1966 to October 2006), EMBASE (1980 to October 2006), Current Contents (1992 to October 2006), references of retrieved articles, and abstracts submitted to the Society for Pediatric Research (1996 to 2006).Selection criteriaRandomised controlled trials of antenatal magnesium sulphate therapy given to women threatening or likely to give birth at less than 37 weeks' gestational age.Data collection and analysisWe independently extracted data regarding clinical outcomes including paediatric mortality, neurologic outcome of survivors (including blindness, deafness, cerebral palsy and major neurosensory disability), and maternal complications and side-effects. At least two authors assessed trial eligibility and quality, and extracted data.Main resultsFour trials (3701 babies) were eligible for this review. No statistically significant effect of antenatal magnesium sulphate therapy was detected on any major paediatric outcome, including mortality (e.g., paediatric mortality relative risk (RR) 0.97; 95% confidence interval (CI) 0.74 to 1.28; four trials; 3701 infants), and neurological outcomes in the first few years of life, including cerebral palsy (RR 0.77; 95% CI 0.56 to 1.06; four trials; 3701 infants), neurological impairments or disabilities. There were also no significant effects of antenatal magnesium therapy on combined rates of mortality with neurologic outcomes. There was a significant reduction in the rate of substantial gross motor dysfunction (RR 0.56; 95% CI 0.33 to 0.97; two trials; 2848 infants). There were higher rates of minor maternal side-effects in the magnesium groups, but no significant effects on major maternal complications.Authors' conclusionsThe role for antenatal magnesium sulphate therapy as a neuroprotective agent for the preterm fetus is not yet established. Given the possible beneficial effects of magnesium sulphate on gross motor function in early childhood, outcomes later in childhood should be evaluated to determine the presence or absence of later potentially important neurologic effects, particularly on motor or cognitive function. Further information will be available from one of the studies where outcomes are being evaluated again at eight to nine years of age, and from another trial currently in progress.http://www.wiley.com/WileyCDA/WileyTitle/productCd-EBC2.htm
Probability Experiments in the Secondary School
No full textThis article, created by L.W. Gates of Gillingham Technical High School, describes complete instructions for two probability experiments targeting middle school aged students. The author states, "Probability theory is taught as part of the normal curriculum in most secondary schools, but it is not usually possible, due to shortage of time, lack of equipment, or teacher reluctance to perform probability experiments." This lesson attempts to alleviate these issues in a secondary school setting
Geographic profiling in Nazi Berlin: fact and fiction
No full textGeographic profiling uses the locations of connected crime sites to make inferences about the probable location of the offender’s ‘anchor point’ (usually a home, but sometimes a workplace). We show how the basic ideas of the method were used in a Gestapo investigation that formed the basis of a classic German novel about domestic resistance to the Nazis during the Second World War. We use modern techniques to re-analyse this case, and show that these successfully locate the Berlin home address of Otto and Elise Hampel, who had distributed hundreds of anti-Nazi postcards, after analysing just 34 of the 214 incidents that took place before their arrest. Our study provides the first empirical evidence to support the suggestion that analysis of minor terrorism-related acts such as graffiti and theft could be used to help locate terrorist bases before more serious incidents occur
Bilateral and unilateral arm training improve motor function through differing neuroplastic mechanisms: a single-blinded randomized controlled trial
No full textBACKGROUND AND PURPOSE:
This randomized controlled trial tests the efficacy of bilateral arm training with rhythmic auditory cueing (BATRAC) versus dose-matched therapeutic exercises (DMTEs) on upper-extremity (UE) function in stroke survivors and uses functional magnetic resonance imaging (fMRI) to examine effects on cortical reorganization.
METHODS:
A total of 111 adults with chronic UE paresis were randomized to 6 weeks (3×/week) of BATRAC or DMTE. Primary end points of UE assessments of Fugl-Meyer UE Test (FM) and modified Wolf Motor Function Test Time (WT) were performed 6 weeks prior to and at baseline, after training, and 4 months later. Pretraining and posttraining, fMRI for UE movement was evaluated in 17 BATRAC and 21 DMTE participants.
RESULTS:
The improvements in UE function (BATRAC: FM Δ = 1.1 + 0.5, P = .03; WT Δ = -2.6 + 0.8, P < .00; DMTE: FM Δ = 1.9 + 0.4, P < .00; WT Δ = -1.6 + 0.7; P = .04) were comparable between groups and retained after 4 months. Satisfaction was higher after BATRAC than DMTE (P = .003). BATRAC led to significantly higher increase in activation in ipsilesional precentral, anterior cingulate and postcentral gyri, and supplementary motor area and contralesional superior frontal gyrus (P < .05). Activation change in the latter was correlated with improvement in the WMFT (P = .01).
CONCLUSIONS:
BATRAC is not superior to DMTE, but both rehabilitation programs durably improve motor function for individuals with chronic UE hemiparesis and with varied deficit severity. Adaptations in brain activation are greater after BATRAC than DMTE, suggesting that given similar benefits to motor function, these therapies operate through different mechanisms
Interview of L.W. Jay, February 21, 2010
No full textThis is a recording of a woman interviewing L.W. Jay who worked in the Atlanta Rome district. He states he started working for the church in 1958 or 1959, and was appointed as minister of Butler Street in the 1960s, and was appointed by Peter Randolph Shy. He talks about how during his tenure, churches moved, sold and were built depending on the congregation, and the culture of the different churches. He lists the churches that were under his direction, and how some other churches suffered financial problems and pulled out of districts. He talks about situations happening in the different churches, mainly from the Hosley Temple and Mount Sinai churches.The Atlanta University Center Robert W.

13C hyperfine coupling constants in MuC60
No full text13C hyperfine coupling constants of the MuC60 radical have been measured by muon level-crossing spectroscopy, using a dilute solution of 99% enriched 13C60 in decalin. The signs as well as the magnitudes of the hyperfine constants were determined. The results range from 52.6 to −25.4 MHz and support those calculations which predict an extended distribution of unpaired electron spin density in radical adducts of fullerenes. The hyperfine constants are consistent with published electron spin resonance results for (CD3)3CC60, but contradict a recent report for HC60, where a considerably smaller value is reported for the largest splitting.

No full textEarly developmental screening and intervention for high-risk neonates - from research to clinical benefits
No full textWith advances in neonatal care there has been an increase in survival rates for infants born very preterm and/or with complex needs, such as those who require major surgery, who may not have survived decades ago. Despite advances in survival, these infants remain at high-risk for a range of neurodevelopmental delays and/or impairments including motor, cognitive and emotional/behavioural challenges. Research has improved our ability to identify which infants are at high-risk of developmental delay and/or impairments, and there is mounting evidence that early interventions can improve outcomes of these infants. However, clinical practice varies throughout the world regarding recommendations for developmental screening. Moreover, intervention, when available, is often not commenced early enough in development. Given limited resources, those infants most at risk of developmental impairments and their families should be targeted, with further research needed on the cost-effectiveness of surveillance and early interventions.Alicia Jane Spittle, Peter John Anderson, Sarah Jane Tapawan, Lex William Doyle, Jeanie Ling Yoong Cheon
