Optical near field enhancements in the vicinity of particles illuminated by laser light are increasingly recognized as a powerful tool for nanopatterning applications, but achieving sub-wavelength details from the near-field distribution remains a challenge. Here we present a quantitative analysis of the spatial modulation of the near optical fields generated using single 8 ps, 355 nm (and 532 nm) laser pulses around individual colloidal particles and small close packed arrays of such particles on silicon substrates...

We report in this Letter a two-phase structured laser illumination planar imaging [two-pulse SLIPI (2p-SLIPI)] optical setup where the "lines structure" is spatially shifted by exploiting the birefringence property of a calcite crystal. By using this optical component and two cross-polarized laser pulses, the shift of the modulated pattern is not "time-limited" anymore. Consequently, two sub-images with spatially mismatched phases can be recorded within a few hundred of nanoseconds only, freezing the motion of the illuminated transient flow...

The development of fever is a common complication in the clinical course of cancer. If all other potential causes of fever are excluded, the possibility of neoplastic fever should be considered. The aim of the present study was to determine the incidence of neoplastic fever in patients with bone and soft tissue sarcomas. Between January 2009 and December 2014, 195 patients with bone and soft tissue sarcoma (111 men and 84 women; mean age, 55 years) were admitted to the Department of Orthopaedic Surgery of Mie University Graduate School of Medicine (Tsu, Japan)...

BACKGROUND: Prostaglandins (PGs), particularly prostaglandin D2 (PGD2), E2 (PGE2), and I2 (PGI2), are considered to play a role in migraine pain. In humans, infusion of PGD2 causes lesser headache as compared to infusion of PGE2 and PGI2. Follow-up studies in rats have shown that infusion of PGE2 and PGI2 dilate the middle meningeal artery (MMA), and mRNA for PGE2 and PGI2 receptors is present in rat trigeminovascular system (TVS) and in the brain structures associated with pain. In the present study, we have characterized the dilatory effect of PGD2 on rat MMA and studied the relative mRNA expression of PGD2 receptors and lipocalin-type of PGD2 synthase (L-PGDS)...

This double cohort study aimed to evaluate the effect of tailored dietary guidance for pregnant women on dietary intake, nutritional status, and infant birth weight. Healthy pregnant women were recruited at an antenatal clinic during two phases over 2 years. The historical controls were analyzed a year prior to the intervention group. In both groups, data were collected at 19-26 gestational weeks (baseline) and at 34-37 gestational weeks (outcome measurement). The intervention included the following: (a) assessments of maternal dietary nutritional intake using the brief self-administered diet history questionnaire, (b) individual feedback based on the assessments of maternal nutritional status, (c) tailored guidance for a healthy diet, (d) original cooking recipes, and (e) goal sharing...

Brain diseases such as autism and Alzheimer's disease (each inflicting >1% of the world population) involve a large network of genes displaying subtle changes in their expression. Abnormalities in intraneuronal transport have been linked to genetic risk factors found in patients, suggesting the relevance of measuring this key biological process. However, current techniques are not sensitive enough to detect minor abnormalities. Here we report a sensitive method to measure the changes in intraneuronal transport induced by brain-disease-related genetic risk factors using fluorescent nanodiamonds (FNDs)...

INTRODUCTION: There is a controversy in the literature whether stress and related cortisol responses are beneficial or impairing for cognitive functioning. Conflicting results might be due to individual differences in stress reactivity and cognitive load of the applied tasks. METHODS: N = 48 participants underwent the Socially Evaluated Cold Pressor Test and were confronted with the Frankfurter Aufmerksamkeits-Inventar-2 (FAIR-2) which is a low-load attention task and two subscales of the Intelligenz-Struktur-Test 2000 R (I-S-T 2000R) as a high-load reasoning task before and after the stressor...

Studies on gene-environment interactions suggest that some individuals may be more susceptible to life adversities than others due to their genetic profile. This study assesses whether or not children with an extra X chromosome are more vulnerable to the negative impact of early life stress on cognitive functioning than typically-developing children. A total of 50 children with an extra X chromosome and 103 non-clinical controls aged 9 to 18 years participated in the study. Cognitive functioning in domains of language, social cognition and executive functioning were assessed...

BACKGROUND: Esophagectomy for patients with esophageal cancer is associated with high rate of postoperative infectious complications (PICs). Although minimally invasive esophagectomy (MIE) could reduce the rate of PICs, its incidence cannot be ignored. Early detection of PICs may be beneficial in clinical settings. We investigated whether systemic inflammation markers, such as C-reactive protein (CRP) and white blood cell count (WBC), are useful for the early detection of PICs. METHOD: We reviewed 158 patients who underwent MIE from 2000 to 2015 and assessed PIC incidence and severity...

Non-contact precise manipulation of single microparticles, cells, and organisms has attracted considerable interest in biophysics and biomedical engineering. Similar to optical tweezers, acoustic tweezers have been proposed to be capable of manipulating microparticles and even cells. Although there have been concerted efforts to develop tools for non-contact manipulation, no alternative to complex, unifunctional tweezer has yet been found. Here we report a simple, low-cost, multifunctional single beam acoustic tweezer (SBAT) that is capable of manipulating an individual micrometer scale non-spherical cell at Rayleigh regime and even a single millimeter scale organism at Mie regime, and imaging tissue as well...

Terminal duct lobular units (TDLUs) are the predominant source of future breast cancers, and lack of TDLU involution (higher TDLU counts, higher acini count per TDLU and the product of the two) is a breast cancer risk factor. Numerous breast cancer susceptibility single nucleotide polymorphisms (SNPs) have been identified, but whether they are associated with TDLU involution is unknown. In a pooled analysis of 872 women from two studies, we investigated 62 established breast cancer SNPs and relationships with TDLU involution...

BACKGROUND: Activated leukocytes infiltrating the liver contribute to the provocation of alcoholic hepatitis. Glucocorticoid induces the demargination of leukocytes from the hepatic sinusoids, whereas granulocyte-monocyte absorptive apheresis (GMA) removes leukocytes from the circulation. Thus, the usefulness of a sequential therapy consisting of glucocorticoid infusions followed by GMA was evaluated in patients with severe alcoholic hepatitis. METHODS: Patients with severe alcoholic hepatitis received intravenous injections of methylprednisolone (1,000 mg/day) for 3 or 4 days, and then GMA was performed every day for 3 days...

Jianqi Shen, Xiaowei Jia, Haitao Yu
It has been proved that localized approximation (LA) is the most efficient way to evaluate the beam shape coefficients (BSCs) in generalized Lorenz-Mie theory. The BSCs are usually expressed in the form of multiple summations of an infinite series of terms, which is cumbersome to calculate, and the infinite series is frequently slowly convergent. In this paper, we present a compact expression of the BSCs for an elliptical Gaussian beam based on the LA that is more convenient and efficient for numerical computations...

We demonstrate that Digital Holographic Microscopy can be used for accurate 3D tracking and sizing of a colloidal probe trapped in a diamond anvil cell (DAC). Polystyrene beads were optically trapped in water up to Gigapascal pressures while simultaneously recording in-line holograms at 1 KHz frame rate. Using Lorenz-Mie scattering theory to fit interference patterns, we detected a 10% shrinking in the bead's radius due to the high applied pressure. Accurate bead sizing is crucial for obtaining reliable viscosity measurements and provides a convenient optical tool for the determination of the bulk modulus of probe material...

This work introduces a Markov Chain solution to model photon multiple scattering through turbid slabs via anisotropic scattering process, i.e., Mie scattering. Results show that the proposed Markov Chain model agree with commonly used Monte Carlo simulation for various mediums such as medium with non-uniform phase functions and absorbing medium. The proposed Markov Chain solution method successfully converts the complex multiple scattering problem with practical phase functions into a matrix form and solves transmitted/reflected photon angular distributions by matrix multiplications...
