A spectrum of neurological disorders characterized by abnormal neuronal migration, differentiation, and axon guidance and maintenance have recently been attributed to missense and splice-site mutations in the genes that encode α-tubulin and β-tubulin isotypes TUBA1A, TUBA8, TUBB2B, and TUBB3, all of which putatively coassemble into neuronal microtubules. The resulting nervous system malformations can include different types of cortical malformations, defects in commissural fiber tracts, and degeneration of motor and sensory axons. Many clinical phenotypes and brain malformations are shared among the various mutations regardless of structural location and/or isotype, while others segregate with distinct amino acids or functional domains within tubulin. Collectively, these disorders provide novel paradigms for understanding the biological functions of microtubules and their core components in normal health and disease. 相似文献

Nanomaterial-based biosensing strategies offer a number of advantages over traditional molecular diagnostic and cellular analysis techniques, including signal amplification, improved sensitivity and speed, and versatile sensing schemes that can be tailored to a desired target. In this article, we highlight a variety of nanomaterial-based sensors, and discuss the advantages of different nanomaterials compositions and probes of different biomolecular classes. Recent advances in the development of optical, electrical, or electrochemical transduction mechanisms are covered, with special regard to breakthroughs in sensitivity. The works reviewed herein emphasize the improvements that nanomaterials offer in the realm of diagnostic assays and make a solid case for further advancement with automation and multiplexing. 相似文献

Background
Hypertension is one of the leading causes of cardiovascular disease (CVD). A range of antihypertensive drugs exists, and their prices vary widely mainly due to patent rights. The objective of this study was to explore the cost-effectiveness of different generic antihypertensive drugs as first, second and third choice for primary prevention of cardiovascular disease.Methods
We used the Norwegian Cardiovascular Disease model (NorCaD) to simulate the cardiovascular life of patients from hypertension without symptoms until they were all dead or 100 years old. The risk of CVD events and costs were based on recent Norwegian sources.Results
In single-drug treatment, all antihypertensives are cost-effective compared to no drug treatment. In the base-case analysis, the first, second and third choice of antihypertensive were calcium channel blocker, thiazide and angiotensin-converting enzyme inhibitor. However the sensitivity and scenario analyses indicated considerable uncertainty in that angiotensin receptor blockers as well as, angiotensin-converting enzyme inhibitors, beta blockers and thiazides could be the most cost-effective antihypertensive drugs.Conclusions
Generic antihypertensives are cost-effective in a wide range of risk groups. There is considerable uncertainty, however, regarding which drug is the most cost-effective. 相似文献7.

We developed a molecular imaging agent (MIA), a conjugable form of PK11195 (conPK11195) coupled to a lissamine dye (Liss-ConPK11195), which targets the peripheral benzodiazepine receptor (PBR). To determine that our compound specifically binds to this 18 kDa protein, primarily expressed on the mitochondria, we performed classic binding studies on live MDA-MB-231 breast cancer cells and measured fluorescence in cell fractions of C6 glioma cells. We found that conPK11195 conjugated to the fluorophore retained significant binding to its target. Here we demonstrate the utility of the agent for in vitro imaging of live cells by specific binding to the protein of interest. 相似文献
