Abstract
The ultrafast laser excitation of matters leads to nonequilibrium states with complex solid-liquid phase-transition dynamics. We used electron diffraction at mega-electron volt energies to visualize the ultrafast melting of gold on the atomic scale length. For energy densities approaching the irreversible melting regime, we first observed heterogeneous melting on time scales of 100 to 1000 picoseconds, transitioning to homogeneous melting that occurs catastrophically within 10 to 20 picoseconds at higher energy densities. We showed evidence for the heterogeneous coexistence of solid and liquid. We determined the ion and electron temperature evolution and found superheated conditions. Our results constrain the electron-ion coupling rate, determine the Debye temperature, and reveal the melting sensitivity to nucleation seeds.

Abstract
OBJECTIVE The purpose of this study is to evaluate the histocompatibility and feasibility of structure and function of bone marrow mesenchymal stem cells (BMSCs) and silk fibroin meniscus porous scaffolds in repairing meniscus injury in rabbits. MATERIALS AND METHODS BMSCs were cultured and identified in vitro, silk fibroin meniscus porous scaffolds were prepared and the histocompatibility of porous scaffolds was evaluated via in vitro culture. Silk fibroin-BMSCs porous scaffolds were implanted into the meniscus defect area of New Zealand white rabbits as the experimental group, the blank scaffold group without BMSCs, pure BMSCs group and blank control group were set up with 10 rabbits in each group. Joint capsules were opened for general observation at 6 weeks and 12 weeks after operation. The specimens received the HE staining, alkaline toluidine blue staining, and immunohistochemical staining of Type I and Type II collagen and S100 protein. RESULTS In vitro HE staining and SEM observation showed that the scaffolds showed the sponge-like structure with abundant microporous structure on the surface and inside, which had a good histocompatibility with BMSCs. At 6 and 12 weeks after operation in experimental group, meniscus-like tissues were found in the meniscus defect area. HE staining showed the fibrous cartilage-like structure and obvious collagenous fiber structure around arranged in an orderly manner. Alkaline toluidine blue staining showed the cartilage-specific glycosaminoglycan (GAG); Type I and Type II collagen and S100 protein staining were strongly positive. However, the above changes were not seen in other groups. CONCLUSIONS BMSCs and silk fibroin meniscus porous scaffolds have a better histocompatibility and feasibility of structure and function in repairing meniscus injury in rabbits.

Abstract
OBJECTIVE Previous studies have shown that BC029135, a long noncoding RNA (lncRNA) with high conservation, was decreased with high fold change in colorectal cancer (CRC) by using microarray assay. In the present work, we investigated the functions of BC029135 in CRC, as well as the potential mechanisms underlying the malignant phenotype caused by loss of BC029135. MATERIALS AND METHODS Bioinformatics analysis of lncRNA BC029135 was performed to identify the potential function. The cell lines of HCT-116, SW480, SW620, LoVo, SW1116, and HT29 were used in this study. The mRNA expression of BC029135 and β-actinin was measured by Real-Time Polymerase Chain Reaction (RT-PCR). Western blot analysis was used to determine protein expression of β-actinin, MMP-2, cyclin D1, and c-Myc. RESULTS Our research showed that the expression of BC029135 in CRC tissues and cell lines was significantly lower than in adjacent normal tissues. In addition, overexpression of lncRNA BC029135 could inhibit the invasion of CRC cells. We also found that lncRNA BC029135 inhibits Wnt/β-catenin signaling in CRC cell lines. CONCLUSIONS We suggest that up-regulation of BC029135 suppresses CRC invasion and inactivates Wnt/β-catenin signaling. It will provide new insights for the treatment of colorectal cancer and new clues for clinical treatment.

Abstract
Quantitative information is scarce in current obesity medication guidelines, and they do not clearly reflect the differences in the efficacy characteristics among various drugs. This study quantitatively assessed the efficacy characteristics of five FDA-approved long-term weight loss drugs. Potentially eligible studies were obtained from public databases. Using the differences in the weight change from baseline between the drug group and the corresponding placebo group as the major indicator of efficacy, a time-effect model was established, and crucial pharmacodynamic parameters, such as the maximal efficacy, drug onset time and rate of body weight regain after the maximal efficacy point, were used to reflect the differences in efficacy among the five drugs. Finally, 50 reports (involving 43,443 participants) were included. After deducting the placebo effects, the maximal efficacies (95% CI) of orlistat (120 mg), lorcaserin, naltrexone-bupropion, phentermine-topiramate (PT, 7.5/46 mg) and liraglutide were -2.94 (-5.82, -1.27), -3.06 (-4.39, -1.71), -6.15 (-9.78, -3.25), -7.45 (-9.76, -3.88) and -5.50 (-10.62, -2.97) kg at weeks 60, 54, 67, 59 and 65 respectively, and their rates of body weight regain were 0.51, 0.48, 0.91, 1.27and 0.43 kg per year respectively. The 1-year dropout rates of orlistat, lorcaserin, naltrexone-bupropion, PT and liraglutide were 29.0, 40.9, 49.1, 34.9 and 24.3% respectively. In addition, a significant dose-effect correlation was observed for orlistat and PT. This study provides valid quantitative information for medication guidelines.

Abstract
We apply time-resolved MeV electron diffraction to study the electron-lattice energy relaxation in thin film Au-insulator heterostructures. Through precise measurements of the transient Debye-Waller-factor, the mean-square atomic displacement is directly determined, which allows to quantitatively follow the temporal evolution of the lattice temperature after short pulse laser excitation. Data obtained over an extended range of laser fluences reveal an increased relaxation rate when the film thickness is reduced or the Au-film is capped with an additional insulator top-layer. This behavior is attributed to a cross-interfacial coupling of excited electrons in the Au film to phonons in the adjacent insulator layer(s). Analysis of the data using the two-temperature-model taking explicitly into account the additional energy loss at the interface(s) allows to deduce the relative strength of the two relaxation channels.

Abstract
UNLABELLED A model-based meta-analysis method was performed to quantitatively analyze the efficacy characteristics of calcium intake in BMD increase among postmenopausal women. We found that age and calcium intake dose were key factors affecting the efficiency and onset of BMD change, and daily 1200 mg calcium was suggested to be a beneficial dosage. INTRODUCTION This paper aims to quantify the efficacy of calcium intake in preventing bone mineral density (BMD) decrease among postmenopausal women and to investigate the factors that may affect the efficacy. METHODS Comprehensive literature search was conducted in PubMed and EMBASE from January 2016. Placebo-controlled or no-treatment controlled randomized trials focused on calcium intake for the management of osteoporosis in postmenopausal women were included. The clinical and demographic characteristics of participants and efficacy data, defined as the mean percentage change of spine BMD (L2-L4) at each observation time point compared with that of baseline, were extracted from the studies. Model-based meta-analysis (MBMA) was used to describe the time course of BMD change by calcium intake and identify the related factors. RESULTS This study includes 17 trials involving 2537 subjects. The results showed that a classic pharmacodynamic maximal effect (E max) model could describe the time course of BMD change by calcium intake. Using this model, we found that age and calcium intake dose were key factors affecting the efficiency and onset of BMD change. A 60-year-old woman administered with 800 mg/day calcium can achieve a maximum BMD increasing rate of 2.38%, and the time to reach 50% of this maximum (known as onset time) was 9.44 months. An increase of 0.0817% per year was noted in the maximal effect value for women aged between 50 and 83 years. For calcium dose interval from 250 to 2000 mg/day, the onset time was expressed as 9.44 × (dose/800)-1.33 months. Two-year calcium intake of 700, 1200, and 2000 mg/day resulted in a maximum efficacy of BMD of 68.0, 81.3, and 89.6%, respectively. This indicates that the final efficacy had already reached the plateau (>80% E max) under the 1200-mg/day dose. CONCLUSION Calcium intake can effectively postpone the tendency of BMD decrease in postmenopausal women. An increased calcium dose contributes to the shortening of the onset time. Considering the drug-acting rate and safety into account, menopausal women can be administered with a rational dose of 1200 mg/day to reduce bone loss.

Abstract
The chemistry of the Earth's atmosphere close to the surface is known to be strongly influenced by vegetation. However, two critical aspects of the forest environment have been neglected in the description of the large-scale influence of forests on air pollution: the reduction of photolysis reaction rates and the modification of vertical transport due to the presence of foliage. Here we show that foliage shading and foliage-modified vertical diffusion have a profound influence on atmospheric chemistry, both at the Earth's surface and extending throughout the atmospheric boundary layer. The absence of these processes in three-dimensional models may account for 59–72% of the positive bias in North American surface ozone forecasts, and up to 97% of the bias in forested regions within the continent. These processes are shown to have similar or greater influence on surface ozone levels as climate change and current emissions policy scenario simulations. Fully quantifying the influence of vegetation on atmospheric chemistry remains challenging. Here, the authors show that forest canopy shading and turbulence significantly modify air pollution throughout the atmospheric boundary layer, and must be taken into account in models of the atmosphere.
