Large-Scale Preparation of Micro-Nanofibrous and Fluffy Propylene-Based Elastomer/Polyurethane@Graphene Nanoplatelet Membranes with Breathable and Flexible Characteristics for Wearable Stretchy Heaters.

Effective personal thermal management is crucial for protecting human health during cold weather. Therefore, wearable heaters based on electric-heating membranes are one of the most promising devices to become essential appliances in our daily lives. The main challenge toward this goal is the development of electric-heating membranes with adequate breathable, flexible, and stretchable characteristics.

Co-regulation of rainfall amount and timing on soil carbon mineralization in a typical salt marsh of the Yellow River Delta, China.

Studying the effects of rainfall regimes such as rainfall amount and timing on soil carbon mineralization is of great importance for our understanding the mechanisms underlying the stability and accumulation of soil carbon in coastal salt marshes. In this study, we examined the responses of soil carbon mineralization (CO and CH fluxes) from undisturbed soil columns to rainfall events in different seasons (dry and wet seasons) with filed experiments in a primary region in the Yellow River Delta salt-marsh wetland, which is far away from the coast and not affected by tides. The results showed that rainfall amount and timing had a significant interaction in affecting soil CO flux rates.

Effect of mesotherapy with nanochip in the treatment of facial rejuvenation.

: To observe the clinical effect of mesotherapy with nanochip for facial rejuvenation.: 24 volunteers with aging skin were treated with a polycomponent formulation - NCTF® BOOST 135 HA for 5 times (once weekly for 3 times and successively biweekly for 2 times). Photographs were taken by VISIA at baseline, and after 1, 4, 10 weeks, while global scores for photoaging (GSP), improvement scores, volunteers' satisfaction, parameters describing the properties of the skin, and adverse effects were assessed during each follow-up period.

A real-time detection and positioning method for small and weak targets using a 1D morphology-based approach in 2D images.

A small and weak target detection method is proposed in this work that outperforms all other methods in terms of real-time capability. It is the first time that two-dimensional (2D) images are processed using only one-dimensional1D structuring elements in a morphology-based approach, enabling the real-time hardware implementation of the whole image processing method. A parallel image readout and processing structure is introduced to achieve an ultra-low latency time on the order of nanoseconds, and a hyper-frame resolution in the time domain can be achieved by combining the row-by-row structure and the electrical rolling shutter technique.

[Health Benefit Analyses of the Clean Air Action Plan Implementation in Shanghai].

To understand the public health benefits of the Clean Air Action Plan implemented in Shanghai from 2013-2017, the changes of the PM exposure levels and related health and economic benefits were quantitatively evaluated by using air quality numerical modeling, health risk assessment, and environmental valuation methods. The results show that the proportion of the population exposed to a mean annual PM concentration lower than or equal to 35 μg·m has increased from 1.62% in the base year to 34.

A randomized guinea pig study on external cell growth factors after fractional ultrapulsed CO(2) laser therapy.

Background And Objectives: The Fractional Ultrapulsed CO2 laser has been successfully used in treating fine wrinkles, acne scars, and photoaged skin. However, the downtime typically lasts a week or more. The purpose of this study was to observe the efficacy of external cell growth factors after Fractional Ultrapulsed CO2 laser therapy.

Investigation of digital sun sensor technology with an N-shaped slit mask.

Nowadays sun sensors are being more widely used in satellites to determine the sunray orientation, thus development of a new version of sun sensor with lighter mass, lower power consumption and smaller size it of considerable interest. This paper introduces such a novel digital sun sensor, which is composed of a micro-electro-mechanical system (MEMS) mask with an N-shaped slit as well as a single linear array charge-coupled device (CCD). The sun sensor can achieve the measurement of two-axis sunray angles according to the three sun spot images on the CCD formed by sun light illumination through the mask.

Daily visibility and hospital admission in Shanghai, China.

Objective: The study is to investigate the associations between visibility, major air pollutants and daily counts of hospital admission in Shanghai, China.

Methods: Daily data on hospital admission, visibility, and air pollution during 2005-2008 were obtained from the Shanghai Insurance Bureau (SHIB), Shanghai Meteorological Bureau, and Shanghai Environmental Monitoring Center, respectively. The generalized additive model (GAM) with penalized splines was used to examine the associations between daily visibility and hospital admission.

[Effects of airborne fine particulate matter on human respiratory symptoms and pulmonary function].

Objective: to explore effects of airborne fine particulate matter exposure on human respiratory symptoms and pulmonary function.

Methods: one hundred and seven field traffic policemen were recruited as airborne fine particulate matter high-exposure group and one hundred and one male residents as common exposure group. The individual sampler was used to measure fine particulate matter exposure levels of the two groups.

Association analyses identify six new psoriasis susceptibility loci in the Chinese population.

We extended our previous genome-wide association study for psoriasis with a multistage replication study including 8,312 individuals with psoriasis (cases) and 12,919 controls from China as well as 3,293 cases and 4,188 controls from Germany and the United States and 254 nuclear families from the United States. We identified six new susceptibility loci associated with psoriasis in the Chinese study containing the candidate genes ERAP1, PTTG1, CSMD1, GJB2, SERPINB8 and ZNF816A (combined P < 5 × 10⁻⁸) and replicated one locus, 5q33.1 (TNIP1-ANXA6), previously reported (combined P = 3.

[Progression of study on the health effects of indoor biological contaminants].

The use of HVAC (the heating, ventilation and air conditioning) system which leads to the inadequate circulation of indoor air, together with the popularization of family pets, creates an appropriate environment for survival and reproduction of air-borne microbes. Microbes with their toxin and allergen in air often adhere to saliva and particular matters, landing to the ground or floating in air for long time. Potential adverse health consequences may be led to subjects exposed to the biological contaminants.
