It's That Time Again: Congress Considers NSF Legislation
Beyond making appropriations to fund federal research programs, Congress is responsible for authorizing the activities and funding levels for federal agencies such as the National Science Foundation (NSF). Last renewed by the America COMPETES Act reauthorization of 2010, the agency's authorization is set to expire in 2015. In anticipation, Congress has started work on NSF reauthorization legislation. Amid a sluggish national economy and concomitant contentious political debate about federal budget priorities, some in Congress have questioned in recent years what types of research the government should fund and, periodically, specific research projects. Therefore, as Congress considers the future of the NSF, the science policy community has prepared for potential battles. For the full story, click here.

Kothapalli, J. Thomas BrennaAbstractBranched chain fatty acids (BCFA) and linear chain/normal odd chain fatty acids (n-OCFA) are major fatty acids in human skin lipids, especially sebaceous gland (SG) wax esters. Skin lipids contain variable amounts of monounsaturated BCFA and n-OCFA, in some reports exceeding over 20% of total fatty acids. Fatty acid desaturase 2 (FADS2) codes for a multifunctional enzyme that catalyz...
ConclusionsThe median h-index for an academic thoracic surgeon in Canada and the United States is 10. Surgeons who engage in Twitter activity are more likely to have their research cited by others.
ConclusionsEarly-diastolic phase slope of the HVAD flow waveform might be a novel parameter that can estimate the presence of clinically significant AI.
ConclusionsOnline education for cardiothoracic surgery is seeing increased public use, with high ratings for content and utility. Despite aggressive marketing to STS members, most remain unaware of this website’s existence. Those who are aware approve of its content, but adoption of referring patients to it has been slow. Improved strategies are necessary to make surgeons aware of this STS-provided service and to increase patient referrals to it.
This study evaluated outcomes associated with treatment strategies for this nonagenarian population.MethodsTreatment and overall survival for patients 90 years and older with NSCLC in the National Cancer Data Base (2004-2014) were evaluated using logistic regression, the Kaplan-Meier method, and multivariable Cox proportional hazard models.ResultsThe majority (n = 4152, 57.6%) of the 7205 patients 90 years or older with stage I-IV NSCLC did not receive any therapy. For the entire cohort, receiving treatment was associated with significantly better survival when compared with no therapy (5-year survival, 9.3% [95% confidenc...
ConclusionsThe delay in surgical resection of StageIIIa NSCLC is not associated increased early mortality, however it is associated with worse 3-year post-resection survival.
Publication date: March 2020Source: Interdisciplinary Neurosurgery, Volume 19Author(s): Joel Kaye, Ahmed Meleis, Shabbar Danish, Zhenggang XiongAbstractMeningiomas are relatively slow-growing, typically benign tumors that arise from the arachnoid cells which form the meninges. They are the most common primary brain tumor and account for nearly one-third of all primary brain and spine tumors. Meningiomas can arise from any dural site, however they are infrequently found at the cerebellopontine angle (CPA). While WHO grade I meningiomas are benign and the slowest growing, WHO grade II meningiomas grow significantly faster, d...
We present a case of Moyamoya disease in an infant who presented with neurological symptoms including convulsions and motor deficits. He was misdiagnosed two times and finally investigated in a tertiary hospital with brain computed tomography and magnetic resonance imaging showing affected vessels with typical pattern of Moyamoya diseases in the brain. He underwent surgical intervention and scheduled for follow up.
ConclusionsIn the current series, the factors which were associated with an increased rate of iatrogenic pituitary injury were: increased manipulation of the gland intra-operatively, a firm tumor consistency not amenable to suction or curettage, and larger pituitary adenoma size. Recognition of the heterogeneity of macroadenoma consistency and growth patterns and appropriate usage of intra- and/or extra-capsular tumor resection techniques may help mitigate the risk of surgical pituitary injury.
Conclusion. The hexane extract of L. apiculata leaves showed the lower MIC against S. aureus when compared with extracts obtained from other parts of the plant. The growth curve and the colonies count suggest a bacteriostatic activity of the L. apiculata leaves extract against Staphylococcus aureus. PMID: 31737073 [PubMed]
