A Novel Frequency-Selective Surface-Enhanced Composite Honeycomb Absorber with Excellent Microwave Absorption.

Multifunctional structures with excellent wave-absorbing and load-bearing properties have attracted much attention in recent years. Unlike other wave-absorbing materials, honeycomb wave-absorbing materials have appealing radar absorption and mechanical properties. However, the existing honeycomb wave-absorbing materials have problems such as narrow absorption band and poor compression resistance.

Characterization of chicken IFI35 and its antiviral activity against Newcastle disease virus.

Interferon-induced protein-35 kDa (IFI35) was an antiviral protein induced by interferon (IFN)-γ, which plays an important role in the IFN-mediated antiviral signaling pathway. Here, we cloned and identified IFI35 in the chicken for the first time. Chicken IFI35 (chIFI35) contains an open reading frame (ORF) of 1,152 bp encoding a protein of 384 amino acids containing two conserved Nmi/IFI35 domain (NID) motifs.

[Impact analysis of atmospheric state for target detection in hyperspectral radiance image].

Target detection based on hyperspectral radiance images can improve data processing efficiency to meet the requirements of real-time processing. However, the spectral radiance acquired by the remote sensor will be affected by the atmosphere. In the present paper, hyperspectral imaging process is simulated to analyze the effects of the changes in atmospheric state on target detection in hyperspectral radiance image.

Optimization of fatty alcohol biosynthesis pathway for selectively enhanced production of C12/14 and C16/18 fatty alcohols in engineered Escherichia coli.

Background: With the increasing stress from oil price and environmental pollution, aroused attention has been paid to the microbial production of chemicals from renewable sources. The C12/14 and C16/18 alcohols are important feedstocks for the production of surfactants and detergents, which are widely used in the most respected consumer detergents, cleaning products and personal care products worldwide. Though bioproduction of fatty alcohols has been carried out in engineered E.

Localized expression of human BMP-7 by BM-MSCs enhances renal repair in an in vivo model of ischemia-reperfusion injury.

Ischemia and subsequent reperfusion (I/R) damage kidney tubular cells and consequently impair renal function. Rabbit bone marrow mesenchymal stem cells (BM-MSCs) expressing human bone morphogenic protein-7 (hBMP-7) regenerated tubular cells and improved renal function in a kidney I/R model. Rabbits were injected immediately after I/R with one of the following: (i) hBMP-7-transduced BM-MSCs (BM-MSCshBMP-7); (ii) enhanced green fluorescent protein-transduced BM-MSCs (BM-MSCsEGFP); or (iii) PBS.

FSCB phosphorylation in mouse spermatozoa capacitation.

It is generally accepted that spermatozoa capacitation is associated with protein kinase A-mediated tyrosine phosphorylation. In our previous study, we identified the fibrous sheath CABYR binding protein (FSCB), which was phosphorylated by PKA. However, the phosphorylation status of FSCB protein during spermatozoa capacitation should be further investigated.

Essential role for p53 and caspase-9 in DNA damaging drug-induced apoptosis in neuroblastoma IMR32 cells.

Neuroblastoma is a solid tumor of the sympathetic nervous system accounting for up to 10% of pediatric cancers and 15% of cancer-related deaths. It is a useful system for investigation of stress signal-mediated apoptosis as a tumor suppression mechanism. In this study, we present evidence that p53 mediates DNA damaging drug-induced apoptosis in IMR32 cells through the caspase-9 pathway.

[Effects of tourism disturbance on plant diversity in Qingshan Lake scenic area of Zhejiang Province].

From May 2007 to June 2008, an investigation was made on the changes of plant community in Qingshan Lake scenic area of Zhejiang Province under the effects of tourism disturbance. With the increase of tourism disturbance, the importance value of the plants was mainly fastened on a few species such as Pinus hwangshanensis, apt to decrease for tree and shrub species and to increase for herb species, and the individuals of the plants increased. The values of richness index (D) and diversity index (H) were in the order of medium disturbance > slight disturbance > severe disturbance, while the evenness index (J) value was in the order of medium disturbance > severe disturbance > slight disturbance.

Enhancement of palladium-porphyrin room temperature phosphorescence by alkaline earth metal in deoxycholate aggregates solution.

Room temperature phosphorescence (RTP) of three palladium (Pd)-phorphyrins in air-saturated solution of sodium deoxycholate (NaDC) aggregates was measured. RTP of Pd-meso-tetrakis (4-carboxyphenyl) porphyrin (Pd-TCPP) was obviously enhanced in NaDC-aggregates mediated by alkaline earth metal (AEM). Under the same experimental conditions, Ca(2+), Ba(2+) and Mg(2+) induced 200, 90 and 24 times greater enhancement in RTP of Pd-TCPP, respectively.

[Summer habitat selection of alpine musk deer in Xinglongshan National Nature Reserve, Northwestern China].

During July and August from 2006 to 2008, summer habitat selection was studied in Alpine musk deer (Moschus sifanicus) in Xinglongshan National Natural Reserve in northwestern China. In total, seventy one musk deer utilized habitat plots and 246 random habitat plots were surveyed. Seventeen habitat characteristics were recorded and compared between the two habitat types, using Mann-Whitney U test and chi-square to compare the differences between utilized and random habitat plots, and principal component analysis (PCA) to determine the main factors influencing the habitat selection of musk deer.

[Prophylactic effect of inductive intravesical instillation of Bacillus Calmette-Guerin on postoperative recurrence of bladder cancer].
