In this study, alumina-reinforced poly(methyl methacrylate) nanocomposites (PMMA/Al2O3) containing up to 20vol% nanoparticles with an average diameter of 50nm were prepared by friction stir processing. The effects of nanoparticle volume fraction on the microstructural features and mechanical properties of PMMA were studied. It is shown that by using a frustum pin tool and employing an appropriate processing condition, i.e. a rotational speed of 1600rpm/min and transverse velocity of 120mm/min, defect free nanocomposites at microscale with fine distribution of the nanoparticles can successfully been prepared...

DNA mismatch repair (MMR)-deficient cancers accumulate high numbers of coding microsatellite mutations, which lead to the generation of highly immunogenic frameshift peptide (FSP) neoantigens. MMR-deficient cells can grow out to clinically manifest cancers either if they evade immune cell attack or if local T-cells get exhausted. Therefore, a subset of MSI cancer patients responds particularly well to treatment with immune checkpoint inhibitors. We analyzed whether immune evasion in MMR-deficient cancer mediated by loss of HLA class I or II antigens is related to local immune cell activation status...

Barış K Yörük
In volume 36 of this journal, using data from the National Longitudinal Study of Youth, 1997 Cohort (NLSY97), Yörük (2014) finds that the false ID laws with scanner provision (FSP laws) significantly reduce underage drinking. In a recent paper, Zheng (2018) argues that analyses based on the NLSY97 data fail falsification exercises and uses data from the Youth Risk Behavior Surveillance System (YRBSS) to estimate the effectiveness of the FSP laws. This paper replies to Zheng (2018) and provides new results from the NLSY97, which show that the FSP laws were effective reducing several indicators of alcohol consumption among minors...

Marine fish skin peptides (FSP) have been widely studied due to their antioxidant and antimicrobial properties. We aimed to use a natural antioxidant, FSP, to replacing synthetic preservatives in a pork patty model, which is safer for human body. Moreover, nano-liposome technology can be applied for masking the fishy smell and improving the stability of this peptide. Therefore, in this study, the effects of FSP and FSP-loaded liposomes (FSPL) on pork patty were evaluated through the tests of thiobarbituric acid reactive substances (TBARS), color, cooking loss, texture, volatile basic nitrogen (VBN), and the pH value, during 14 d of refrigerated (4°C) storage...

Near-infrared light allows measuring tissue oxygenation. These measurements relay on oxygenation dependent absorption spectral changes. However, the tissue scattering, which is also spectral dependent, introduces an intrinsic error. Most methods focus on the volume reflectance from a semi-infinite sample. We have proposed examining the full scattering profile (FSP), which is the angular intensity distribution. A point was found, i.e. the iso-pathlength (IPL) point, which is not dependent on the tissue scattering, and can serve for self-calibration...

Trans-boundary air pollution (TAP) is a crucial factor affecting air quality, and its contribution may vary over time and differ under various atmospheric conditions. This study firstly applies an integrated statistical scheme to estimate the contributions of TAP and local sources to air pollutants in a city, and then investigate the influences of tropical cyclones (TC) on TAP. Hong Kong is chosen as an example because of its significant and special TAP characteristics. This study focuses on four major air pollutants, namely, respirable and fine suspended particulates (RSP/PM10 and FSP/PM2...

Asthma is a common chronic respiratory disease in children that is caused by a complex interaction between genetic and environmental factors. Orosomucoid‑like 3 (ORMDL3) is a candidate gene that has been strongly associated with asthma; however, the underlying mechanisms are unknown. ORMDL3 regulates the expression of metalloproteinases and transforming growth factor‑β, and ORMDL3 transgenic mice exhibit increased airway remodeling. Therefore, ORMDL3 may be associated with airway remodeling. The present study attempted to examine the associations between ORMDL3 and the severity of airway remodeling in asthmatic mice, and also to determine whether ORMDL3 induces epithelial‑mesenchymal transition (EMT) in the bronchial epithelium...

Dilated cardiomyopathy (DCM) is characterized by left ventricular dilation and cardiac fibrosis. Emerging evidence indicated that endothelial‑to‑mesenchymal transition (Endo‑MT) is a crucial event during organ fibrosis. This study was performed to clarify whether Endo‑MT contributed to the progression of cardiac fibrosis in DCM. Cardiac samples from patients with DCM and control were obtained. The presence of endothelial markers, cluster of differentiation (CD)31 and vascular endothelial (VE)‑cadherin, and mesenchymal markers, α smooth muscle actin (SMA) and fibroblast‑specific protein 1 (FSP1) was performed using immunohistochemistry...

CuO-Cu2O heterojunction was synthesized via a one-step flame spray pyrolysis (FSP) process and employed as photoactive material in construction of a photoelectrochemical (PEC) sensing device. The surface analysis showed that CuO-Cu2O nanocomposites in the size less than 10 nm were formed and uniformly distributed on the electrode surface. Under visible light irradiation, the CuO-Cu2O-coated electrode exhibited admirable cathodic photocurrent response, owing to the favorable property of the CuO-Cu2O heterojunction such as strong absorption in the visible region and effective separation of photogenerated electron-hole pairs...

Monte Carlo methods such as the stochastic simulation algorithm (SSA) have traditionally been employed in gene regulation problems. However, there has been increasing interest to directly obtain the probability distribution of the molecules involved by solving the chemical master equation (CME). This requires addressing the curse of dimensionality that is inherent in most gene regulation problems. The finite state projection (FSP) seeks to address the challenge and there have been variants that further reduce the size of the projection or that accelerate the resulting matrix exponential...
