Aims: To investigate the association between circulating oxidized low-density lipoprotein (ox-LDL) levels and progression of subclinical atherosclerosis and to examine whether this link is independent of other low-density lipoprotein (LDL)-related parameters.Methods: Totally, 804 subjects who were free of cardiovascular disease at baseline completed risk factor surveys and carotid ultrasound measurements in 2002 and 2012. Modified Poisson regression was performed to examine the association between baseline serum ox-LDL levels and the 10-year risk of progression of carotid atherosclerosis which was defined as the development of at least one new plaque in a previously plaque-free carotid segment at re-examination.Results: The mean age of the subjects was 58.6±7.7 years at baseline and 43.3% were men. A total of 504 (62.7%) subjects had carotid plaque progression at re-examination. Subjects in the intermediate and highest tertiles of ox-LDL had a significantly higher adjusted risk of atherosclerosis progression than those in the lowest tertile [relative risk (95% confidence interval) 1.17 (1.01–1.34) for the intermediate tertile and 1.23 (1.07–1.42) for the highest tertile]. This association was independent of baseline levels of LDL-C, total LDL particle number, and small LDL particle number.Conclusion: This study demonstrates that serum ox-LDL levels predict 10-year progression of subclinical atherosclerosis. Moreover, this effect is independent of the cholesterol content, the number, and the size of LDL particles.

The microbial communities inhabiting the fronds of duckweeds have not been investigated in as much detail as those on the roots. We herein examined the microbial communities in three duckweed species using 16S rRNA amplicon sequencing and compared them to those on the roots. The microbial compositions of the fronds were distinct from those of the roots in the three species. Various types of taxonomic bacteria, including rarely cultivated phyla, Acidobacteria, Armatimonadetes, and Verrucomicrobia, were also isolated from the fronds, but at a slightly lower abundance than those from the roots. These results suggest that duckweed fronds are an alternative source for isolating rare and novel microbes, which may otherwise be recalcitrant to cultivation using conventional strategies.

It has been argued that the Coupled Model Intercomparison Project phase 5 (CMIP5) models underestimate the frequency of atmospheric blocking, while projecting a decreasing trend of blocking in the 21st century in the Northern Hemisphere. This average trend may not be true for regional blockings. Focusing on three key regions in Eurasia (the Urals, Baikal, and Okhotsk regions) where blocking significantly influences the weather and climate of East Asia, this study first evaluates the performance of the CMIP5 models by comparing historical simulations with National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis (NNR). Possible changes in the first half of the 21st century are then analyzed using the RCP4.5 and RCP8.5 experiments. It is found that instantaneous blocking frequencies are underestimated in the Urals and Baikal regions for the whole year and in the Okhotsk region in summertime but are overestimated in Okhotsk in wintertime. Blocking episode frequency in the Urals and Baikal regions is underestimated by most of the 13 CMIP5 models, especially the short-duration blocking episodes (4–5 days), and the simulations are better in wintertime than in summertime. However, in the Okhotsk region, the modeled frequency of blocking episodes is close to the value from NNR in summertime but is overestimated in wintertime. Model projections of instantaneous blocking frequency for the first half of the 21st century (2016–2065) show that both RCP4.5 and RCP8.5 runs yield an increasing frequency except during June–August in Eurasia. The multimodel ensemble-mean frequency of blocking episodes clearly decreases in the whole year in the Urals and Baikal regions (especially blocking episodes with short duration) and increases a little in summertime in the Okhotsk region in the first half of the 21st century. The model ensemble-mean frequency of blocking episodes with long duration (more than 9 days) decreases by ~40 % in the Urals region but increases by no more than 5 % in Okhotsk region.

This paper presents a four-way current-combining Ka-band power amplifier (PA) in 65-nm CMOS technology. A symmetrical, transmission line based four-way current combiner, together with output transformers, is used to transfer the high load impedance (4*ZL) to the desired Zopt for each power unit cell. Besides, both interstage/input flexible matching transformers and the power splitter are optimized to improve the performance. Based on the methodology mentioned above, the power amplifier demonstrates a small-signal gain of about 24.12 dB, a saturated output power of 21.56 dBm, and a peak power-added efficiency of 27.3% at 35GHz.

Background: Epidemiological evidence on the relationships between different categories of vegetables and fruits and depressive symptoms is very limited and inconsistent, especially with no evidence from the general population. This study aimed to estimate their relationships among a large general population.Methods: The cross-sectional design was based on the National Health and Nutrition Examination Survey (2007–2014) and included 16925 adults. Dietary information was attained from two nonconsecutive 24-h dietary recalls. Patient Health Questionnaire was applied for measuring depressive symptoms. The associations between vegetables and fruits intakes and depressive symptoms were appraised utilizing logistic regression and restricted cubic spline.Results: Compared with the lowest category, the most adjusted odds ratios (95% confidence intervals, CI) of depressive symptoms for the highest category of tomatoes and tomato mixtures were 0.81 (95% CI, 0.66-0.99), and 0.64 (95% CI, 0.48-0.85) for dark-green, 0.67 (95% CI, 0.53-0.84) for other vegetables, 0.48 (95% CI, 0.29-0.79) for berries, 0.67 (95% CI, 0.55-0.82) for total vegetables, and 0.70 (95% CI, 0.57-0.86) for total fruits, and for the medium categories of bananas and dried fruits were 0.62 (95% CI, 0.41-0.95) and 0.39 (95% CI, 0.19-0.81), respectively. After sensitivity analysis by further excluding subjects with co-morbid health conditions, these findings remained significant, except for bananas. An L-shaped relationship was observed between depressive symptoms and total vegetables, while the association was linear with total fruits.Conclusions: Intakes of tomatoes and tomato mixtures, dark-green, other vegetables, berries, dried fruits, total vegetables, and total fruits were inversely related to depressive symptoms among adults.

The novel silica nanotubes with flower-like morphology and hexagonal outer surface morphology were fabricated via a simple ZnS nanowires templates-assisted CVD method. The as-synthesized nanotubes exhibited strong visible photoluminescence at 615 nm and indicated that the method was useful to produce silica nanotubes.
