The extraordinary responsiveness and large diversity of self-assembled structures of liquid crystals are well documented and they have been extensively used in devices like displays. For long, this application route strongly influenced academic research, which frequently focused on the performance of liquid crystals in display-like geometries, typically between flat, rigid substrates of glass or similar solids. Today a new trend is clearly visible, where liquid crystals confined within curved, often soft and flexible, interfaces are in focus...

AIMS: A proportion of patients with pancreatic cancer never develop metastatic disease. We evaluated a role for (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) in identifying a subset of patients with locally advanced pancreatic cancer (LAPC) who never develop metastatic disease and only experience local disease and may therefore benefit from local treatment intensification. MATERIAL AND METHODS: Patients with histologically confirmed LAPC entered a single-centre phase II study of definitive upfront chemoradiotherapy (CRT)...

BACKGROUND: Angiogenesis, a process of generation of new blood vessels from the pre-existing vasculature, has been demonstrated to be a basic prerequisite for sustainable growth and proliferation of tumour. Anti-angiogenic treatments show normalization of tumour vasculature and microenvironment at least transiently in both preclinical and clinical settings. METHODS: In this study, we proposed a multi-scale mathematical model to simulate the dynamic changes of tumour microvasculature and microenvironment in response to anti-angiogenic drug endostatin (ES)...

Background The efficacy and safety of bevacizumab in elderly patients with non-small cell lung cancer remain controversial. This study focused on both selecting fit elderly patients and overcoming interpatient variability with respect to pharmacodynamics. Methods Elderly (age: ≥70 years) patients with advanced non-squamous non-small cell lung cancer were enrolled. Patients with uncontrolled congestive heart failure and uncontrolled diabetes were excluded. The treatment regimen comprised carboplatin at an area under the curve of 5 mg/ml/min on day 1, paclitaxel at 90 mg/m(2) on days 1 and 8, and bevacizumab at 15 mg/kg on day 1 every 21 days for up to 4 cycles, followed by maintenance bevacizumab...

Ptychography is used to characterize the phase response of a spatial light modulator (SLM). We use the technique to measure and correct the optical curvature and the gamma curve of the device. Ptychography's unique ability to extend field of view is then employed to test performance by mapping the phase profile generated by a test image to subpixel resolution over the entire active region of the SLM.

Afterloading brachytherapy is conducted by the stepwise movement of a radioactive source through surgically implanted applicator tubes where at predefined dwell positions calculated dwell times optimize spatial dose delivery with respect to a planned dose level. The temporal exposure pattern exhibits drastic fluctuations in dose rate at a given coordinate and within a single treatment session because of the discontinuous and repeated source movement into the target volume. This could potentially affect biological response...

Angiogenesis is an important pathophysiological response to cerebral ischemia, and can be modulated by vascular endothelial growth factor (VEGF) and endostatin. Circulating endothelial progenitor cells (EPCs) also play an important role as an endogenous repair mechanism for ischemic injury. We sought to investigate early changes in the expression of VEGF and endostatin in serum and the circulating EPCs in patients with acute ischemic stroke (AIS) and analyzed the relations between them. The peripheral blood and serum samples were obtained from 30 patients at 1, 3, 5 and 7 d after AIS...
