SummaryThe effects of resveratrol (RSV) addition on quality of fractionated wheat flour and the corresponding cooked white‐salted noodles were investigated. Commercial wheat flour was fractionated into four particle size groups, that is <45, 45–65, 65–105 and >105 μm. RSV was incorporated into the fractionated flour at three different levels. Swelling power increased in each of the four particle size groups with the addition of RSV. RSV at 0.5% led to a decrease in rapidly digestible starch and an increase in slowly digestible starch. Antioxidant capacity increased with the addition of RSV except for the >105 μm particle size group, which declined in oxygen radical absorbance capacity value. Smaller particle size could increase antioxidant capacity, but extremely small particle size may decrease it. Addition of RSV increased tensile strength and decreased hardness of cooked noodles. This study showed that resveratrol addition to wheat flour had potential to bring quality and health benefits.

AbstractBackgroundReliable exposure information is crucial for assessing health outcomes of influenza infection and vaccination. Current serological methods are unable to distinguish between anti‐hemagglutinin (HA) antibodies induced by infection or vaccination.ObjectivesWe aimed to explore an alternative method for differentiating influenza infection and vaccination.MethodsSera from animals inoculated with influenza viruses or purified H1N1pdm09 HA were obtained. Human samples were selected from a pregnancy cohort established during the 2009 H1N1 pandemic. Unvaccinated, laboratory‐confirmed cases (N = 18), vaccinated cases without influenza‐like‐illness (N = 18) and uninfected, unvaccinated controls (N = 18) were identified based on exposure data from questionnaires, national registries and maternal hemagglutination inhibition (HI) titres at delivery. Animal and human samples were tested for antibodies against the non‐structural protein 1 (NS1) and HA from H1N1pdm09, using a Luciferase Immunoprecipitation System (LIPS).ResultsAnti‐NS1 H1N1pdm09 antibodies were detected in sera from experimentally infected, but not from vaccinated, animals. Anti‐HA H1N1pdm09 antibodies were detectable after either of these exposures. In human samples, 28% of individuals with laboratory‐confirmed influenza were seropositive for H1N1pdm09 NS1, whereas vaccinated cases and controls were seronegative. There was a trend for H1N1pdm09 NS1 seropositive cases reporting more severe and longer duration of symptomatic illness than seronegative cases. Anti‐HA H1N1pdm09 antibodies were detected in all cases and in 61% of controls.ConclusionsThe LIPS method could differentiate between sera from experimentally infected and vaccinated animals. However, in human samples obtained more than 6 months after the pandemic, LIPS was specific, but not sufficiently sensitive for ascertaining cases by exposure.

AbstractRegeneration has long been the focus of scientific interest for its potential to restore lost, damaged, or aged tissues and organs. A wide range of regenerative studies have been conducted on different vertebrate and invertebrate model organisms. Annelids are known for their regenerative capacities, and because of their relatively complex organ systems, they are an ideal organism for regeneration study. Our present work focused on the freshwater annelid Aeolosoma viride, an asexually reproducing annelid capable of regenerating both anteriorly and posteriorly. Even though regenerative ability has been documented in this animal in previous studies, detailed characterization of the process is still unavailable. The objective of this study was to evaluate the regenerative ability of A. viride. We described the sequential morphological events during the process of regeneration, such as wound healing and the formation of blastema, mouth, and pygidium. In order to clarify the capacity and type of regeneration, we conducted a series of observations and experiments using a cell proliferation assay. Massive proliferation and the absence of cell migration indicated that the animal regenerates primarily through epimorphosis. Our study of the epimorphic regenerative process of A. viride provides a clearer picture of the evolutionary origin of regeneration in annelids.

AbstractOxyfluoride glass and glass‐ceramics are being studied due to the possibility of their utilization in many applications, such as thermoluminescent dosimeters, optical fibers, fluorescent concentrators, and temperature sensors. In order to improve the properties of glass, they are often crystallized. For this crystallization to be effective, knowledge and control of the structure of the starting material is required. Much work was done on silicate glass; however, a great interest exists in obtaining these kinds of materials in other matrices such as germanates, phosphates, and borates. Here, we present a structural study of some oxyfluoride borate glass with different concentrations of PbF2 by means of Nuclear Magnetic Resonance (NMR), Raman, and Fourier Transform Infrared (FTIR) spectroscopies. We also analyzed glass‐crystallization using Differential Scanning Calorimetry (DSC). The crystallization study was complemented with the use of Transmission Electron Microscopy (TEM) and Selected Area Electron Diffraction (SAED), for the purpose of identifying possible mechanisms of crystallization. Our results indicate, from the structural point of view, that the glass present groups with one or two BO4 species, such as diborate or pentaborate. The small variation in the BO4 fraction with the increase in PbF2 concentration would be an indication of the formation of F−BO3/2 species. Oxyfluoride borate glass containing BaO as a cation modifier and 30% PbF2 represents a good starting point for obtaining glass‐ceramics with a narrow size distribution of BaF2 nanocrystals. We also propose that the possible mechanism for oxyfluoride borate glass crystallization started with a separation of phases.

AbstractInelastic deformation of anomalous glasses manifests in shear flow and densification of the glass network; the deformation behavior during indentation testing is linked strongly to both processes. In this paper, the indentation densification field of fused silica is investigated using depth‐resolved Raman spectroscopy and finite element simulations. Through affecting the size of the indent, the normal load and the Raman laser spot size determine the spatial sampling resolution, leading to a certain degree of structural averaging. For appropriate combinations of normal load (indent size) and laser spot diameter, a maximum densification of 18.4% was found at the indent center. The indentation behavior was modeled by extended Drucker‐Prager‐Cap (DPC) plasticity, assuming a sigmoidal hardening behavior of fused silica with a densification saturation of 21%. This procedure significantly improved the reproduction of the experimental densification field, yielding a maximum densification of 18.2% directly below the indenter tip. The degree of densification was found to be strongly linked to the hydrostatic pressure limit below the indenter in accordance to Johnson's expanding cavity model (J. Mech. Phys. Solids, 18 (1970) 115). Based on the good overlap between FEA and Raman, an alternative way to extract the empirical correlation factor m, which scales structural densification to Raman spectroscopic observations, is obtained. This approach does not require the use of intensive hydrostatic compaction experiments.

Published: January 2020

AbstractCarbon‐bonded carbon fiber (CBCF) composites are promising lightweight and high efficient thermal insulators to be applied in aerospace area, but their practical applications are usually restricted by the low mechanical performance and poor oxidation resistance. To overcome these drawbacks, many efforts have been made in the fabrication of ceramic coated CBCF composites. However, the densities of these modified composites are usually very high, which would result in the reduction in their thermal insulation performance. Herein, we prepared a CBCF composite with SiC nanowires enhanced interfibrous junctions and SiOC ceramic coated carbon fibers (SiCNWs‐SiOC‐CBCF). Similar to CBCF, the SiCNWs‐SiOC‐CBCF exhibits a low density of 0.35 g/cm3 and an anisotropic and highly porous architecture. The SiCNWs‐SiOC‐CBCF possesses a compressive strength of 3.8 MPa and a compression modulus of 195.7 MPa in the X (or Y) direction, ~26.7% and 150% higher than those of CBCF respectively. It can also suffer from an isothermal treatment in air at 900°C for 120 minutes. The combination of these properties makes the SiCNWs‐SiOC‐CBCF a good candidate for thermal insulator to be applied in extreme conditions.

Published: January 2020

AbstractFrequency conversion using nonlinear optical (NLO) crystals is widely used in advanced photonic technologies to produce coherent light in the spectral regions where the available laser sources are missing. Isotropic glasses usually do not show second order nonlinear processes like second harmonic or difference frequency generation (SHG, DFG) except for temporarily induced anisotropy under external stimuli. Here, we show that a HgI2–Ga2S3–GeS2 homogeneous glass exhibits a strong intrinsic SHG response comparable with that of the well‐known NLO single crystal LiNbO3. The origin of this extremely rare phenomenon seems to be noncentrosymmetric bent HgI2 molecules embedded in a sulfide glassy host. Taking into account the unique properties of chalcogenide glasses (wide IR transmission, low phonon density, unlimited ability to be modified changing the appropriate glass properties, fiber drawing and thin layer design), the observed phenomenon opens up the possibility of creating fundamentally new devices for mid‐IR photonics.
Thermal history and its implications: A case study for ion exchange
Authors: Zhang Liying , Guo Xiaoju 
Published: January 2020

AbstractGlasses containing monovalent species can be chemically strengthened by the replacement of smaller ions in the glass with larger external ions in the near glass surface. This type of ion exchange puts glass surface under high compressive stress (CS). Glass mainly fails from tension with the presence of surface flaws. Chemical strengthening can change the stress at the flaw tip from tension to compression and further stop the flaw from propagating. Glass damage resistance is therefore significantly improved. For the same glass composition, glass thermal histories can affect the magnitude and depth of the CS generated during ion exchange. In this study, the impact of thermal history on glass physical properties and ion exchange attributes in one alkali‐containing glass formed by fusion draw process was investigated. Multiple thermal treatments were done to rewrite the glass thermal histories. Glass density, refractive index, and ion‐exchange properties as a function of the thermal treatment were studied. It is concluded that ion exchange‐related properties change dramatically with the glass thermal history.

AbstractCardiovascular Disease (CVD) is the leading cause of deaths worldwide, contributing to about 30% of all deaths. Half of the cases of CVD are estimated in Asia, the world's most populous continent. Hypertension, a major modifiable risk factor for CVD, results in more deaths than any other CV risk factors in the Asian regions. The total number of patients with hypertension is likely to grow as the population ages. The proportion of the elderly population aged 65 years or more in Asia is expected to increase from 7.4% in 2015 to 10.9% in 2030. It is important to note that more than half (54%) of the world's population live in Asia. Aside of being the biggest single risk factor for global deaths, hypertension is also an important precursor and most common risk factor of heart failure (HF). An increase in HF prevalence is clearly related to the rapid epidemiological transition caused by changes in lifestyle in Asian countries. However, the availability of data on HF burden and health care delivery is limited in Asia compared with Europe and North America. This reality has driven the working group of Asian experts for example the HOPE Asia Network to concentrate on hypertension as risk factors for CVD, with the mission to improve the management of hypertension resulting in organ protection toward a goal of achieving “ZERO” CV event in Asia. This paper aims to give an overview regarding the heart problems caused by hypertension in Asia, focus on HF.
Prognostic value of left ventricular hypertrophy in hypertensive patients: A meta‐analysis of electrocardiographic studies
Authors: Zhang Hongsheng , Hu Lingai , Wei Xiqing 
Published: January 2020

AbstractElectrocardiographic left ventricular hypertrophy (LVH) has been used to predict adverse outcomes in different clinical settings. This meta‐analysis aimed to compare the prognostic value of different electrocardiographic criteria of LVH at baseline in hypertensive patients. A systematic literature search was conducted in PubMed and Embase databases until December 3, 2019. Cohort studies that reported the association of baseline electrocardiographic LVH (Sokolow‐Lyon voltage, Cornell voltage or Cornell product) with all‐cause mortality or major cardiovascular events in hypertensive patients were included. The prognostic value of LVH was expressed by the risk ratio (RR) with 95% confidence interval (CI). Nine studies involving 41 870 hypertensive patients were identified. Comparison with those with and without LVH patients indicated that the pooled RR value of all‐cause mortality was 1.30 (95% CI 1.01‐1.66) for the Sokolow‐Lyon voltage criteria, 1.33 (95% CI 1.20‐1.47) for the Cornell voltage criteria, and 1.31 (95% CI 0.97‐1.78) for the Cornell product criteria. In addition, the pooled RR of major cardiovascular events was 1.53 (95% CI 1.27‐1.86) for the Sokolow‐Lyon criteria and 1.46 (95% CI 1.22‐1.76) for the Cornell voltage criteria, respectively. This meta‐analysis suggests that different electrocardiographic criteria for detecting LVH at baseline differ in prediction of all‐cause mortality in patients with hypertension. LVH detected by the Cornell voltage and Sokolow‐Lyon criteria can independently predict the major cardiovascular events in hypertensive patients.
Asian management of hypertension: Current status, home blood pressure, and specific concerns in India
Authors: Sogunuru Guru Prasad , Mishra Surabhi 
Published: January 2020

AbstractSystemic hypertension and its related complications are the important contributing factors for major adverse cardiovascular events all over the world. Evidence from Asia and even from India reveals that both its incidence and prevalence are increasing even in young population both in urban and rural areas. The HOPE (Hypertension Cardiovascular Outcome Prevention and Evidence) Asia network data clearly say that most of these hypertensive patients are undiagnosed and undertreated. Even among the treated patients, the regular follow‐up visits and compliance of antihypertensive drug intake are not effective. The blood pressure variability (BPV) and the exaggerated morning blood pressure surge (MBPS) leading to high cardiovascular mortality and morbidity have been demonstrated in many studies. The role of home blood pressure monitoring (HBPM) to detect BPV and MBPS to treat hypertensive patients more effectively has been published by the HOPE Asia Network. This article is to review the evidence and literature from the Indian perspective and the role of HBPM for the effective control of hypertension in general population.

AbstractDespite limited evidence on the association between physical activity (PA) and blood pressure (BP) in youth, experts recommend that adolescents engage regularly in moderate‐to‐vigorous PA. We examined the relationships between PA intensity and frequency and the likelihood of having high BP in a population‐based cohort of adolescents from Montréal, Canada. PA was self‐reported every 3 months from grade 7 to 11, and BP was measured at ages 12.8, 15.2, and 17.0 years on average. We analyzed data from 993 participants (mean [SD] age = 16.0 [1.0], 51.6% female) with BP data at ages 15.2 and/or 17.0 years, using pooled ordinal logistic regression. BP (normal/elevated/hypertensive range) was the outcome, and past‐year PA intensity and frequency were potential predictors. Eight percent of participants had elevated BP (120‐129/<80), and 3.2% had BP in the hypertensive range (≥130/≥80). Participants engaged in a median (interquartile range) of 7.0 (4.5, 9.3) and 5.5 (2, 10.8) moderate and vigorous PA sessions/week, respectively. After adjusting for age, sex, mother's education, use of alcohol and cigarette consumption, engaging in PA more intense than light during the previous year was associated with a lower odds of having BP in the hypertensive range (ORs [95% CIs] = 0.93 [0.88, 0.97] to 0.97 [0.94, 0.99]). The relationships were not altered by adjusting for BMI. Our findings support recommendations that adolescents engage in at least moderate PA on a regular basis to prevent development of BP in the hypertensive range.

AbstractMasked hypertension (MH) is defined as normal office blood pressure (BP) and elevated ambulatory BP (ABP) or home BP or both. This study assessed the association of MH (ie, isolated home, isolated ABP and dual MH) with echocardiographic left ventricular hypertrophy (LVH). The present analysis of the PAMELA study included 1087 untreated and treated participants with normal office BP and a measurable LV mass (LVM). A total of 193 individuals (17.7%) had any MH (ie, normal office BP, elevated ABP or home BP or both), 48 had dual MH (25%), 62 isolated ambulatory MH (32%), and 83 isolated home MH (43%). Average LVM indexed to body surface area was superimposable in the three MH phenotypes (being the largest difference between groups <3 g/m2) and significantly higher than in true normotensives. This was also for the LVH prevalence that varied across the MH subgroups in a narrow range (from 8.3% to 10.8%). In conclusion, individuals from the general population with isolated MH, in which either home or ABP was elevated, exhibited an increased risk of LVH similar to that entailed by dual MH. Our findings add the notion both home and ABP measurements are useful to more accurately assess the risk of LVH associated with MH in the community.

AbstractPulse wave velocity (PWV), a measure of arterial stiffness, and intima‐media thickening (IMT), a measure of early atherosclerosis, are intermediate markers of cardiovascular disease which are predictive of cardiovascular events. Traditionally, both were thought to result from accumulative exposure to traditional cardiovascular risk factors. However, their association with risk factors in young adults in low‐income settings is unknown. We sought to investigate the association between PWV and IMT with traditional cardiovascular risk factors in the Andhra Pradesh Children and Parents Study cohort from Southern India. Male and female adults (N = 1440) aged between 20 and 24 years underwent measures of PWV and IMT. Exposure variables included smoking, body mass index (BMI), mean arterial pressure (MAP), glucose, homeostatic model assessment of insulin resistance (HOMA‐IR), total cholesterol, high‐density lipoprotein cholesterol (HDL‐cholesterol), and triglycerides. Association between outcome and exposure variables was assessed using linear regression analysis. Average values for PWV and IMT were 5.9 ± 0.6 m/s and 0.5 ± 0.1 mm. In univariable analysis, PWV associated with MAP, BMI, smoking, total cholesterol, glucose, and HOMA‐IR and IMT associated with MAP, BMI, tobacco use, and HDL‐cholesterol. In multivariable analysis, PWV remained strongly positively associated with MAP increasing by 0.5 m/s (P < .001) for a 10 mm Hg increase in MAP (R2 = .37). In contrast, IMT negatively associated with HDL‐cholesterol (β = −.10; P = .012, R2 = .02). There was weak evidence that PWV and IMT positively associated with BMI. In young adults from Southern India, PWV positively associated with blood pressure and IMT negatively associated with HDL‐cholesterol. This suggests separate etiologies for atherosclerosis and arterial stiffening in young adults.
