Inner ear barriers to nanomedicine-augmented drug delivery and imaging

There are several challenges to inner ear drug delivery and imaging due to the existence of tight biological barriers to the target structure and the dense bone surrounding it. Advances in imaging and nanomedicine may provide knowledge for overcoming the existing limitations to both the diagnosis and treatment of inner ear diseases. Novel techniques have improved the efficacy of drug delivery and targeting to the inner ear, as well as the quality and accuracy of imaging this structure. In this review, we will describe the pathways and biological barriers of the inner ear regarding drug delivery, the beneficial applications and limitations of the imaging techniques available for inner ear research, the behavior of engineered nanomaterials in inner ear applications, and future perspectives for nanomedicine-based inner ear imaging.

左心房黏液瘤脱落致右冠状动脉栓塞及心肌梗死一例

与冠状动脉粥样硬化所致心肌梗死不同,黏液瘤脱落所致冠状动脉栓塞并不存在明显血栓负荷,故治疗重点在于尽早再血管化,而非抗栓治疗。虽然抽吸导管在改善急性心肌梗死的预后方面仍存在争议,但对于此类肿瘤组织所致机械栓塞而言,其作用应大于球囊扩张。尽管动脉粥样硬化年轻化趋势愈发明显,该病例亦提示我们在青年心肌梗死诊治中应尽可能拓宽诊断思路、调整治疗思路,方能减少此类疾病的误诊误治。
Lophomonas blattarum: Is it Only its Morphology that Prevents its Recognition?

To the Editor: We have read with interest the article published by Li and Gao on Lophomonas blattarum infection. In it, the authors question whether there is adequate evidence to consider this multiflagellated protozoon of significant importance in the context of the respiratory tract. Mu et al. have also suggested that all the cases diagnosed as pulmonary L. blattarum infection reported in China were misdiagnosed.
A Pneumonia Case Associated with Type 2 Polio Vaccine Strains

Since the World Health Assembly endorsed a plan to completely eradicate polio in 1988, the large-scale use of the attenuated oral poliovirus vaccine (OPV) has drastically decreased the number of polio cases.However, the OPV vaccine brings rare but serious adverse consequences, especially in the Type 2 vaccine strains.Most vaccine-associated paralytic poliomyelitis (VAPP) outbreaks are associated with Type 2 polio vaccine strains,and approximately 26-31% of genetically divergent vaccine-derived polioviruses (VDPVs) cases are associated with the Type 2 component of OPV.Other than VAPP cases and VDPVs, Type 2 polio vaccine strains can also cause a variety of illnesses. To the best of our knowledge,no cases of pneumonia resulting from Type 2 polio vaccine strains have been reported. However, here we report an infant case associated with the Type 2 polio vaccine strain.
Left Atrial Mechanical Function and Aortic Stiffness in Middle-aged Patients with the First Episode of Atrial Fibrillation

Background: In the early stages of atrial remodeling, aortic stiffness might be an indication of an atrial myopathy, in particular, atrial fibrosis. This study aimed to investigate the association between left atrial (LA) mechanical function, assessed by two-dimensional speckle tracking echocardiography, and aortic stiffness in middle-aged patients with the first episode of nonvalvular atrial fibrillation (AF). Methods: This prospective study included 34 consecutive patients with the first episode of AF, who were admitted to Kartal Kosuyolu Research and Training Hospital between May 2013 and October 2015, and 31 age- and gender-matched healthy controls. During the 1st month (mostly in the first 2 weeks) following their first admission, 34 patients underwent the first pulse wave measurements. Then, 21 patients were recalled for their second pulse wave measurement at 11.8 ± 6.0 months following their initial admission. Echocardiographic and pulse wave findings were compared between these 34 patients and 31 healthy controls. We also compared the pulse wave and echocardiographic findings between the first and second measurements in 21 patients. Results: Pulse wave analysis showed no significant differences between the AF patients and healthy controls with respect to PWV (10.2 ± 2.5 m/s vs.9.7 ± 2.1 m/s; P = 0.370), augmentation pressure (9.6 ± 7.4 mmHg vs.9.1 ± 5.7 mmHg; P = 0.740), and aortic pulse pressure (AoPP; 40.4 ± 14.0 mmHg vs.42.1 ± 7.6 mmHg, P = 0.550). The first LA positive peak of strain was inversely related to the augmentation pressure (r = -0.30; P = 0.02) and aortic systolic pressure (r = -0.26, P = 0.04). Comparison between the two consecutive pulse wave measurements in 21 patients showed similar results, except for AoPP. In 21 patients, the AoPP at the second measurement (45.1 ± 14.1 mmHg) showed a significant increase compared with AoPP at the first measurement (39.0 ± 10.6 mmHg, P = 0.028), which was also higher than that of healthy controls (42.1 ± 7.6 mmHg, P = 0.000). Conclusion: The association between aortic stiffness with reduced atrial strain and the key role of AoPP in the development of AF should be considered when treating nonvalvular AF patients with normal LA sizes.
Recent Advances of CuAAC Click Reaction in Building Cyclic Polymer

Cyclic polymers have attracted more and more attentions in recent years because of their unique topological structures and characteristic properties in both solution and bulk state. There are relatively few reports on cyclic polymers, partly because of the more demanding synthetic procedures. In recent years,“click” reaction,especially Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC), has been widely utilized in the synthesis of cyclic polymer materials because of its high efficiency and low susceptibility to side reactions. In this review, we will focus on three aspects: (1) Constructions of monocyclic polymer using CuAAC “click” chemistry; (2) Formation of complex cyclic polymer topologies through CuAAC reactions; (3) Using CuAAC “click” reaction in the precise synthesis of molecularly defined macrocycles. We believe that the CuAAC click reaction is playing an important role in the design and synthesis of functional cyclic polymers.

DFT Study of Adsorption of Diazinon, Hinosan, Chlorpyrifos and Parathion Pesticides on the Surface of B36N36 Nanocage and Its Fe Doped Derivatives as New Adsorbents

In this work, we used density functional theory with the Tkatchenko and Scheffler method to investigate the adsorption of diazinon, hinosan, chlorpyrifos, and parathion organophosphorus pesticides on the surface of B36N36 nanocage and its Fe doped derivatives. The assessments revealed that van der Waals interaction is a key factor in organophosphate adsorption on the surface of these nanocages as well as overlapping. The results of Fukui indices and atomic partial charges calculations indicated that these pesticides and nanocages act as nucleophile and electrophile, respectively, and the adsorption sites of all four organophosphates on these nanocages are thiophosphate groups, as well as the aromatic ring in diazinon, and the nitro group in parathion. In addition, the calculated adsorption energies yielded the best result for diazinon, and the best Fe doped B36N36 derivative for adsorbing organophosphates in aqueous solution is the one in which Fe atom is located in the boron position of the square ring of B36N36.
先天性三度房室传导阻滞一例

先天性房室传导阻滞的治疗手段主要是植入永久起搏器,植入指征是有症状的患者或无症状但存在显著的心动过缓、左心室功能不全、宽QRS、或QT间期延长的患者。但是,目前尚没有指南明确推荐完全性房室传导阻滞的患儿起搏器的选择,根据临床经验和研究显示,最初可以选择带频率应答功能的心室按需型(VVIR)起搏器,青春期后可以考虑升级为心房同步心室抑制型/ 房室全能型(VDD/DDD)模式的起搏器。心外膜电极一般用于新生儿的患者,心内电极推荐应用于略年长的患儿。Lotfy等对一组平均年龄2.3岁的患者植入起搏器,随访7年,发现植入心内电极起搏器是安全有效的,并发症少见。当然,未来尚需要更多的长期随访研究来进一步评估先天性房室传导阻滞患儿植入起搏器的安全性和有效性。
Longshore Currents over Barred Beach with Mild Slope

The laboratory experiment and numerical simulations of wave-driven longshore currents by random waves on barred beaches with slopes of 1:100 and 1:40 were conducted to investigate the bimodal feature of mean longshore currents, with emphasis on the location and ratio of two peaks of longshore currents. The location and ratio of two peaks are controlled by the sand bar. The influences of wave heights and beach slopes on the longshore currents are discussed. Numerical simulations were also performed to compute the measured velocity profile, with the emphasis on the effect of lateral mixing, bottom friction and surface rollers on numerical results.
Anisotropic Inflationary Scenario Via Generalized Chaplygin Gas Model

We investigate generalized chaplygin gas for warm inflationary scenario in the context of locally rotationally symmetric Bianchi type I universe model. We assume two different cases of dissipative coefficient, i.e., constant as well as function of scalar field. We construct dynamical equations as well as a relationship between scalar and radiation energy densities under slow-roll approximation. We also derive slow-roll parameters, scalar and tensor power spectra, scalar spectral index, tensor to scalar ratio for analyzing inflationary background during high dissipative regime. We also use the WMAP7 data for the discussion of our parameters.
Mercury mass flow in iron and steel production process and its implications for mercury emission control

The iron and steel production process is one of the predominant anthropogenic sources of atmospheric mercury emissions worldwide. In this study, field tests were conducted to study mercury emission characteristics and mass flows at two iron and steel plants in China. It was found that low-sulfur flue gas from sintering machines could contribute up to 41% of the total atmospheric mercury emissions, and desulfurization devices could remarkably help reduce the emissions. Coal gas burning accounted for 17%–49% of the total mercury emissions, and therefore the mercury control of coal gas burning, specifically for the power plant burning coal gas to generate electricity, was significantly important. The emissions from limestone and dolomite production and electric furnaces can contribute 29.3% and 4.2% of the total mercury emissions from iron and steel production. More attention should be paid to mercury emissions from these two processes. Blast furnace dust accounted for 27%–36% of the total mercury output for the whole iron and steel production process. The recycling of blast furnace dust could greatly increase the atmospheric mercury emissions and should not be conducted. The mercury emission factors for the coke oven, sintering machine and blast furnace were 0.039–0.047 g Hg/ton steel, and for the electric furnace it was 0.021 g Hg/ton steel. The predominant emission species was oxidized mercury, accounting for 59%–73% of total mercury emissions to air.
Photocatalytic parameters and kinetic study for degradation of dichlorophenol-indophenol (DCPIP) dye using highly active mesoporous TiO_2 nanoparticles

Highly active mesoporous TiO_2 of about 6 nm crystal size and 280.7 m~2/g specific surface areas has been successfully synthesized via controlled hydrolysis of titanium butoxide at acidic medium. It was characterized by means of XRD (X-ray diffraction), SEM (scanning electron microscopy), TEM (transmission electron microscopy), FT-IR (Fourier transform infrared spectroscopy), TGA (thermogravimetric analysis), DSC (differential scanning calorimetry) and BET (Brunauer–Emmett–Teller) surface area. The degradation of dichlorophenol-indophenol (DCPIP) under ultraviolet (UV) light was studied to evaluate the photocatalytic activity of samples. The effects of different parameters and kinetics were investigated. Accordingly, a complete degradation of DCPIP dye was achieved by applying the optimal operational conditions of 1 g/L of catalyst, 10 mg/L of DCPIP, pH of 3 and the temperature at 25 ± 3°C after 3 min under UV irradiation. Meanwhile, the Langmuir–Hinshelwood kinetic model described the variations in pure photocatalytic branch in consistent with a first order power law model. The results proved that the prepared TiO_2 nanoparticle has a photocatalytic activity significantly better than Degussa P-25.
Efficiency of sample-based indices for spatial pattern recognition of wild pistachio (Pistacia atlantica) trees in semi-arid woodlands

The efficiency of sample-based indices proposed to quantify the spatial distribution of trees is influenced by the structure of tree stands, environmental heterogeneity and degree of aggregation. We evaluated 10 commonly used distance-based and 10 density-based indices using two structurally different stands of wild pistachio trees in the Zagros woodlands, Iran, to assess the reliability of each in revealing stand structure in woodlands. All trees were completely stem-mapped in a nearly pure (40 ha) and a mixed (45 ha) stand. First, the inhomogeneous pair correlation function [g(r)] and the Clark– Evans index (CEI) were used as references to reveal the true spatial arrangement of all trees in these stands. The sampled data were then evaluated using the 20 indices. Sampling was undertaken in a grid based on a square lattice using square plots (30 m 9 30 m) and nearest neighbor distances at the sample points. The g(r) and CEI statistics showed that the wild pistachio trees were aggregated in both stands, although the degree of aggregation was markedly higher in the pure stand. Three distance- and six density-based indices statistically verified that the wild pistachio trees were aggregated in both stands. The distance-based Hines and Hines statistic (h_t) and the densitybased standardised Morisita (I_p), patchiness (IP) and Cassie (C_A) indices revealed aggregation of the trees in the two structurally different stands in the Zagros woodlands and the higher clumping in the pure stand, whereas the other indices were not sensitive enough.
Vertical distribution characteristics of soil organic carbon content in Caohai wetland ecosystem of Guizhou plateau, China

We selected four kinds of land use types from Caohai wetlands of Guizhou plateau (a total number of 32 soil profiles) to study the distribution characteristics of organic carbon content in soil. With different ways of land use, the organic carbon content of soil profiles and organic carbon density show the tendency of decreasing firstly and then increasing from top to bottom. With the increase of depth, the vertical difference becomes smaller first and then starts increasing. Land reclamation reduces the soil organic carbon content and density, changing its distribution structure in topsoil. The average content of organic carbon in Caohai wetlands are as follows: lake bed silt[marsh wetland[farmland[woodland, the average organic carbon content of lake bed silt, marsh wetland, farmland and woodland are 16.40, 2.94, 1.81 and 1.08 %, respectively. Land reclamation reduces the organic carbon content of soil, therefore the conversion of cultivated lands to wetlands and the increase of forest coverage will help to fix the organic carbon in soil and increase its reserves.

Adaptation of Asia-Pacific forests to climate change

Climate change is a threat to the stability and productivity of forest ecosystems throughout the Asia-Pacific region. The loss of forests due to climate-induced stress will have extensive adverse impacts on biodiversity and an array of ecosystem services that are essential for the maintenance of local economies and public health. Despite their importance, there is a lack of decision-support tools required to evaluate the potential effects of climate change on Asia-Pacific ecosystems and economies and to aid in the development of regionally appropriate adaptation and mitigation strategies. The project Adaptation of Asia-Pacific Forests to Climate Change, summarized herein, aims to address this lack of knowledge and tools and to provide support for regional managers to develop effective policy to increase the adaptive capacity of Asia-Pacific forest ecosystems. This objective has been achieved through the following activities: (1) development of a highresolution climate downscaling model, ClimateAP, applicable to any location in the region; (2) development of climate niche models to evaluate how climate change might affect the distribution of suitable climatic conditions for regionally important tree species; (3) development and application of forest models to assess alternative management strategies in the context of management objectives and the projected impacts of climate change; (4) evaluation of models to assess forest fire risk and the relationship between forest fire and climate change; (5) development of a technique to assess ecosystem carbon storage using LiDAR; and (6) evaluation of how vegetation dynamics respond to climate change using remote sensing technology. All project outputs were developed with a focus on communication and extension to facilitate the dissemination of results to regional forest resource managers to support the development of effective mitigation and adaptation policy.

Monitoring and predicting the soil water content in the deeper soil profile of Loess Plateau, China

Estimation of soil water content (SWC) in deep soil profiles is of crucial importance for strategic management of water resource for sustainable land use in arid and semi-arid zones, as well as for soil and water conservation. Soil properties have a very important effect on SWC. This study aimed to analyze the influence of soil particle size on SWC, for the first time using soil particle size to estimate SWC in deep soil profiles. SWC was measured mainly in farmland, natural grasslands and plantations of Caragana from the surface to more than 20 m depth. The same soil samples were also tested for particle size. The results show that the soil desiccation is formed in the caragana forest in 3–18 m soil layers, but almost no formation in 18–24 m layers; water content of farmland and grassland is different in all soil profiles although they are both shallow rooted plants. Correlation analysis indicated that SWC could be well predicted by clay content and the close correlation between SWC and clay content yielded a coefficient of determination (R~2) of 0.82 and 0.72, respectively, for farmland and grassland. After multiple regression analysis, a regression model was built using SWC, clay content and sand content data, giving R~2=0.66. The model provided reliable estimates of SWC profile based on textural class. This can assist in estimating water depletion by vegetation, by comparing moisture of farmland and grassland soils with that of plantation forests, and in selecting sustainable land use of arid land.
Optimizing and slope determination of final wall for Maiduk Mine with consideration of destabilizer factors

In this research, determination of final slope for Maiduk copper mine of Kerman is investigated according to destabilizing factors of the mine. The development of the Maiduk Mine caused the extension of the mine area and also withdrawal of its wall. So, optimizing possibility of mine slope is essential. Finally, the magnitude of optimized slopes for different walls of the mine in association with executive commands with better factors of safety is provided. The results show that the most important destabilizer factors are the presence of water and pore pressure in the faults and the main joints. With the omission of pore pressure, mine wall for the designed depth is quite stable. This requires a drainage pattern in the lifetime of the mine. In an optimistic point of view, the minimum factor of safety of the wall will be 2.81 even without drainage. This conclusion allows optimizing the slope to its maximum magnitude of 51 degree. With the pessimistic engineering judgment and with the higher SF, the magnitude of the slope is optimized to 47 degree.
