High-throughput single-cell analysis is a challenging target for implementing advanced biomedical applications. An excellent candidate for this aim is label-free tomographic phase microscopy (TPM). In this paper, some of the methods used to obtain TPM are reviewed, analyzing advantages and disadvantages of each of them. Moreover, an alternative tomographic technique is described for live cells analysis, and future trends of the method are foreseen. In particular, by exploiting random rolling of cells while they are flowing along a microfluidic channel, it is possible to obtain phase-contrast tomography thus obtaining complete retrieval of both 3D-position and orientation of rotating cells...

BACKGROUND: Papaverine remains a popular agent to treat intraoperative microsurgical vasospasm. However, the recent shortage has forced surgeons to trial antispasmodic agents unproven in microsurgery, but commonly used in other areas. During this shortage we have trialed topical nitroglycerin to break intraoperative vasospasm. This study aims to analyze the outcomes of this medication on flap complications compared with papaverine. METHODS: All consecutive free flaps performed for breast reconstruction at a single institution were reviewed...

The introduction of drug-eluting stents (DES) significantly reduced angiographic restenosis and the clinical need for revascularization following percutaneous coronary intervention. However, concerns remain regarding the long-term safety and efficacy of DES. The use of durable polymers for drug elution that have limited biocompatibility is thought to contribute toward DES failure, by promoting an adverse local inflammatory response and vascular toxicity. Biodegradable polymer and polymer-free metallic stents represent two novel technological solutions to this challenging clinical problem...

REVIEW
Yongbo Xue, Yong Zhang
BACKGROUND: The circadian clock, which operates within an approximately 24-h period, is closely linked to the survival and fitness of almost all living organisms. The circadian clock is generated through a negative transcription-translation feedback loop. microRNAs (miRNAs) are small non-coding RNAs comprised of approximately 22 nucleotides that post-transcriptionally regulate target mRNA by either inducing mRNA degradation or inhibiting translation. RESULTS: In recent years, miRNAs have been found to play important roles in the regulation of the circadian clock, especially in Drosophila...
