A novel [1＋1] Schiff-base macrocyclic compound 3 has been synthesized from precursor 1, 1,3-bis（2＇- formylphenoxy）-2-propanol, and precursor 2, resorcinol-bis（4-aminophenyl）ether, via condensation and cyclizaction using Ba2＋ as template. The macrocycle 3 was further reduced giving saturated macrocycle 4. The structures of 3 and 4 were characterized by elemental analysis, ~H NMR, IR, and MS spectra, and their structures were determined via single crystal X-ray diffraction studies. X-ray diffraction analysis revealed that the macrocyclic compound 3 has a folded conformation, and the corresponding reduced product 4 adopts a twisted and folded conformation due to its flexible nature. ~ 2013 Bi-Xue Zhu.

This study develops a bottom-up model to quantitatively assess the comprehensive effects of replacing traditional petroleum-powered vehicles with natural gas vehicles（NGVs） in China based on an investigation of the direct energy consumption and critical air pollutant（CAP） emission intensity, life-cycle energy use and greenhouse gas（GHG） emission intensity of NGV fleets. The results indicate that, on average, there are no net energy savings from replacing a traditional fuel vehicle with an NGV. Interestingly, an NGV results in significant reductions in direct CAP and life-cycle GHG emissions compared to those of a traditional fuel vehicle, ranging from 61% to 76% and 12% to 29%, respectively. Due to the increasing use of natural gas as a vehicle fuel in China（i.e. approximately 28.2 billion cubic metres of natural gas in2015）, the total petroleum substituted with natural gas was approximately 23.8 million tonnes（Mt）, which generated a GHG emission reduction of 16.9 Mt of CO2 equivalent and a CAP emission reduction of 1.8 Mt in 2015. Given the significant contribution of NGVs, growing the NGV population in 2020 will further increase the petroleum substitution benefits and CAP and GHG emission reduction benefits by approximately 42.5 Mt of petroleum-based fuel, 3.1 Mt of CAPs and 28.0 Mt of GHGs. By 2030, these benefits will reach 81.5 Mt of traditional petroleum fuel, 5.6 Mt of CAPs and 50.5 Mt of GHGs, respectively.

Objective:To investigate the protective effects and mechanisms of action of dexamethasone and Salvia miltiorrhiza on multiple organs in rats with severe acute pancreatitis (SAP). Methods:The rats were divided into sham-operated, model control, dexamethasone treated, and Salvia miltiorrhiza treated groups. At 3, 6, and 12 h after operation, the mortality rate of different groups, pathological changes, Bcl-2-associated X protein (Bax) and nuclear factor-κB (NF-κB) protein expression levels in multiple organs (the pancreas, liver, kidneys, and lungs), toll-like receptor 4 (TLR-4) protein levels (only in the liver), intercellular adhesion molecule 1 (ICAM-1) protein levels (only in the lung), and terminal deoxynucleotidy transferase mediated deoxyuridine triphosphate (dUTP) nick end labeling (TUNEL) staining expression levels, as well as the serum contents of amylase, glutamate-pyruvate transaminase (GPT), glutamic-oxaloacetic transaminase (GOT), blood urea nitrogen (BUN), and creatinine (CREA) were observed. Results:The mortality rate of the dexamethasone treated group was significantly lower than that of the model control group (Poups were relieved to different degrees (Poups were significantly lower than those in model control groups (Poup was significantly lower than that in the Salvia miltiorrhiza treated group (Poup were significantly lower than those in the dexamethasone treated group (P<0.05).

There are currently many materials for treating residual antibiotics in the environment, but none of them can specifically remove antibiotics. In addition, these materials are not sensitive enough to low concentrations of antibiotics. Here we show that a sensitive and specific material was developed by the preparation of magnetic Fe_(3)O_(4)-PAMAM-antibody complexes for treating tetracycline. The prepared antibody complexes can specifically treat tetracycline from aqueous solutions and the tetracycline removal ability by adsorption was also investigated. Controlled experiments were carried out with the effects of solution pH, temperature, and initial concentration of the tetracycline. The tetracycline was completely removed within 35 min at room temperature 30 ℃ with the maximum removal rate of almost 100%. Therefore, this material for specifically combining antigen and antibody to treat tetracycline indicated good application prospects for the waste water treatment.

A novel framework for remote service discovery and access of IP cameras with Network address Translation (NAT) traversal is presented in this paper. The proposed protocol, termed STDP (Service Trader Discovery Protocol), is a hybrid combination of Zeroconf and SIP (Session Initial Protocol). The Zeroconf is adopted for the discovery and/or publication of local services;whereas, the SIP is used for the delivery of local services to the remote nodes. In addition, both the SIP-ALG (Application Layer Gateway) and UPnP (Universal Plug and Play)-IGD (Internet Gateway Device) protocols are used for NAT traversal. The proposed framework is well-suited for high mobility applications where the fast deployment and low administration efforts of IP cameras are desired.

Antigens and antibodies can bind specifically, so antibiotic antibody shows potential biological and environmental applications on the removal of antibiotic. In the present study, novel antibody complex was synthesized from polyamide-amine dendrimer immobilized tetracycline(TC) antibody with the encapsulation of magnetic Fe3O4 nanoparticles. As-prepared magnetic Fe3O4-PAMAM-antibody complexes were characterized by different techniques such as Fourier transform infrared(FT-IR), X-ray diffraction(XRD), Nuclear magnetic resonance(NMR)and ultraviolet(UV) analysis spectra. The prepared antibody complexes exhibited high adsorption properties for TC from aqueous solutions. These results suggest that the antibody complex expects to be a potential candidate for the wastewater treatment.

Objective Gyrencephaly is a unique structure found in limited species including human beings. Since the expansion of neocortex providing the structure for much more neurons to form complex network, it is of importance to investigate the mechanism of cortex folding conformation. According to previous studies, researchers have found that outer subventricular zone（OSVZ） is specially appears in species with complex neocortex. Further observations suggest that outer radial glial cells may be a major cause of neocortex. At the level of gene expression, A3 is highly expressed in OSVZ. In vivo overexpression A3 showed the potent increase of the number of proliferative progenitors. Besides, A3 knockdown causes neurogenesis defect both in vitro and in vivo. In several loss-of function experiments, A3 knockdown decrease progenitor’s pool with mitotic delay and spindle structure disrupted. Base on the potential function of A3 and related observation, we hypothesize that A3 plays a role in maintaining the basal progenitors self-renew and development potency in OSVZ.

Background: To investigate the effects of unsafe decompression on rat pulmonary endothelial function and its relevant ***: Sixty male Sprague-Dawley(SD) rats were randomly divided into a control group(n=30) and a decompression sickness(DCS) group(n=30). The DCS model was established by placing the rats in the DCS group in a pressurized cabin where they were exposed to a 600 k Pa compressed air environment for 60 min, and the pressure was then reduced by 100 k Pa/min until it reached atmospheric pressure. After the surviving rats in the DCS group and the rats in the control group were anesthetized, their pulmonary arteries were stripped to test the in vitro pulmonary artery endothelium-dependent vasodilation capacity. Western blotting was used to measure the expression and dissociation of endothelial nitric oxide synthase(e NOS) in pulmonary artery tissues and all protein nitration levels in pulmonary artery tissues; reactive oxygen species(ROS) formation was measured via in vitro pulmonary artery superoxide anion probe dihydroethidium(DHE) ***: After experiencing unsafe decompression, 10 of the 30 rats in the DCS group died. The pulmonary artery endothelium-dependent vasodilation capacity in the surviving rats decreased significantly(Poup and the control group was statistically insignificant(P>0.05), but the ratio of e NOS monomer/dimer in the DCS group was significantly higher than that in the control group(Poup were significantly higher than those of the control group(Pount of ROS formation in the pulmonary arteries of the DCS group was significantly higher than that of the control group(Poupling in the pulmonary artery endot
