We describe new developments for the controlled fabrication of monodisperse emulsions using microfluidics. use glass capillary devices to generate single, double, and higher order with exceptional precision. These can serve as ideal templates generating well-defined particles functional vesicles. Polydimethylsiloxane microfluidic are also used picoliter-scale water-in-oil at rates high 10 000 drops per second. have great potential individual microvessels in high-throughput screening...
Multitasking rust ball: The questions of where a tumor is located, whether drugs are properly delivered to the tumor, and what therapeutic response is, could be answered by using simple but smart, drug-loaded superparamagnetic iron oxide nanoparticles that can accumulate in with high efficiency thanks presence rationally engineered polymer coating layers.

Microgel structures such as spherical microgel shells (picture on the upper left) and particles that incorporate quantum dots, magnetic nanoparticles, polymer microparticles (other images) have been prepared by a capillary microfluidic technique. Because these change their volume with changes in temperature, they may find application in, for example, drug delivery.

To evaluate the efficacy of diffusion-weighted imaging (DWI) on 3 Tesla (T) MR to predict tumor response neoadjuvant chemoradiation therapy (CRT) in patients with locally advanced rectal cancer.Thirty-five who underwent CRT and subsequent surgical resection were included. Tumor volume was measured T2-weighted images before after percentage reduction calculated. The apparent diffusion coefficient (ADC) value DWI CRT, change ADC (Δ ADC) histopathologic categorized either as a responder or...
Paget disease is a rare malignancy of the breast characterized by infiltration nipple epidermis adenocarcinoma cells. The clinical features are characteristic and should increase likelihood diagnosis being made. An important point that more than 90% cases associated with an additional underlying malignancy. frequently ductal carcinoma in situ (DCIS) lactiferous ducts nipple-areolar complex; it may even be DCIS or invasive cancer elsewhere breast, at least 2 cm from complex. Nevertheless,...
Objective: To evaluate whether the histopathological differentiation and expression of vascular endothelial growth factor (VEGF) hepatocellular carcinoma (HCC) do show correlation with apparent diffusion coefficient (ADC) value on diffusion-weighted imaging (DWI). Materials Methods:Twenty-seven HCCs from 27 patients who had undergone preoperative liver MRI (1.5T) surgical resection were retrospectively reviewed.DWI was obtained a single-shot, echo-planar sequence in axial plane (b values: 0...
Herein, a self‐powered electronic nose strategy with highly selective gas detection is described. The two‐dimensional microarray based on the triboelectrification between ZnO nanowires and dielectric layers, heterogeneous catalytic reaction occurring NiO nanoparticles. These noses show ability to distinguish four volatile organic compound (VOC) gases (methanol, ethanol, acetone, toluene) limit of 0.1% at room temperature using no external power source.
To evaluate the value of apparent diffusion coefficient (ADC) histogram analysis for predicting tumor recurrence in patients with uterine cervical cancer treated chemoradiation therapy (CRT).Our institutional review board approved this retrospective study and waived informed consent from each patient. Forty-two (mean age, 56 ± 14 years) biopsy-proven squamous cell carcinoma who underwent both pre-treatment pelvic magnetic resonance imaging a 3.0 T scanner concurrent CRT were included. All...
A key challenge in manipulating the magnetization heavy-metal/ferromagnetic bilayers via spin-orbit torque is to identify materials that exhibit an efficient charge-to-spin current conversion. Ab initio electronic structure calculations reveal intrinsic spin Hall conductivity (SHC) for pristine $\ensuremath{\beta}$-W about 60% larger than of $\ensuremath{\alpha}$-W. More importantly, we demonstrate SHC can be enhanced Ta alloying. This corroborated by Berry curvature...

Abstract Hepatocyte‐specific targeting agents are useful for evaluation of the hepatocytic function and monitoring disease progress. Superparamagnetic iron oxide nanoparticles (SPION) bearing terminal galactose groups exhibit a high affinity asialoglycoprotein receptor on hepatocyte surface. In this study, we synthesized characterized dual probe SPION detectable by both nuclear MR imaging modality specifically hepatocytes in vivo. with 12‐nm diameter were functionalized dopamine. Surface...
Superparamagnetic iron oxide nanoparticles (SPIONs) are widely used as T2-contrast agents for magnetic resonance imaging (MRI). Herein we develop various antibiofouling amphiphilic polymer-coated SPIONs using a one-step nanoemulsion method. This methodology yielded ultrasmall SPIONs, of average diameter less than 30 nm, which were stable under physiological conditions. In vitrocell cytotoxicity tests revealed that no SPION showed toxicity even at relatively high concentrations. vivo MRI with...
To compare the effectiveness of radiofrequency ablation (RFA) combined with transcatheter arterial chemoembolization (TACE) surgical resection in patients a single hepatocellular carcinoma (HCC) ranging from 2 to 5 cm.The study participants were enrolled over period 29 months and comprised 37 therapy group 47 group. RFA was performed day after TACE, by open laparotomy. The two groups compared respect length hospital stay, rates major complication, recurrence-free overall survival.Major...
In mobile healthcare, heart rate variability (HRV) is increasingly being used in dynamic patient states. this situation, shortening of the measurement time required. This study aimed to validate ultra-short-term HRV non-static conditions. We conducted electrocardiogram (ECG) measurements at rest, during exercise, and post-exercise recovery period 30 subjects analyzed frequency domains by ECG 10, 30, 60, 120, 180, 240-s intervals, compared values 5-min HRV. For statistical analysis, null...
The aim of this study was to compare the therapeutic effects radiofrequency ablation (RFA) and hepatic resection (HR) with regards procedural morbidity, mortality, overall survival (OS) disease-free (DFS) rates in hepatocellular carcinoma (HCC) patients.Retrospective studies were performed based on medical records 129 patients who underwent curative HR, 57 received RFA for HCC, between 2005 2009. inclusion criteria HCC presence three or fewer nodules 3 cm less diameter a single nodule 5...
Ultrasound-guided percutaneous core needle biopsy (USPCB) is used extensively in daily clinical practice for the pathologic confirmation of both focal and diffuse diseases abdominal viscera. As a guidance tool, US has number clear advantages over computerized tomography or magnetic resonance imaging: fewer false-negative biopsies, lack ionizing radiation, portability, relatively short procedure time, real-time intra-procedural visualization needle, ability to guide almost any anatomic plane,...
