Impact of anthropogenic disturbance on species diversity and vegetation structure of a lowland tropical rainforest of eastern Himalaya, India

Impact of anthropogenic disturbance on species diversity and vegetation structure of a lowland tropical rainforest was studied in the foothills of Eastern Himalaya, India. Tree species richness, density, basal area and the diversity indices were found significantly (P<0.05) decreased with the increasing level of disturbances whereas, shrub density, basal area and herb density significantly increased with increasing disturbance level. In case of shrubs, Simpson's dominance index significantly (P<0.007) increased along the disturbance gradient, whereas Pielou's evenness index significantly (P<0.005) decreased with an increasing level of disturbance. Shannon-Weiner diversity index for herbs significantly (P<0.016) increased with increasing disturbance whereas, Simpson's dominance index was significantly (P<0.013) declined along the disturbance gradient. Results revealed that 10-50 cm dbh classes constituted the highest stem density, and highest basal area was recorded in the >100 cm dbh class in all three sites. Density of the matured trees decreased with increasing DBH whereas, tree basal area tended to increase with increasing DBH in all three sites. Tree species richness was highest in the lower DBH classes. 62.07% of the total tree species regenerated in the largely undisturbed site followed by 50% in the mildly disturbed and 26.32% in the highly disturbed site. The overall regeneration condition was found to be good in the largely undisturbed site. Mildly disturbed site exhibited fair regeneration and so was in the highly disturbed site. Discernable variations in species composition, diversity, regeneration and tree population structure revealed the impact of anthropogenic disturbances on rainforest vegetation dynamics. Higher degree of disturbance was furtherly found not only affecting species diversity but also promoting the growth of invasive weed species. Dominance of Hydnocarpus kurzii and Crypteronia paniculata in the highly disturbed site also indicated that these less-valued timber species may benefit from the vegetation mosaic produced by the disturbance; so differences in abundance of these species may be useful for bio-indication. Furthermore, present study suggests the need of adequate biodiversity conservation measures and adaptation of sustainable forest management approaches in disturbed areas of lowland tropical rainforest in the foothills of eastern Himalaya, India.
Divergent growth trends and climatic response of Picea obovata along elevational gradient in Western Sayan mountains, Siberia

In mountain ecosystems, plants are sensitive to climate changes, and an entire range of species distribution can be observed in a small area. Therefore, mountains are of great interest for climate–growth relationship analysis. In this study, the Siberian spruce's (Picea obovata Ledeb.) radial growth and its climatic response were investigated in the Western Sayan Mountains, near the Sayano- Shushenskoe Reservoir. Sampling was performed at three sites along an elevational gradient: at the lower border of the species range, in the middle, and at the treeline. Divergence of growth trends between individual trees was observed at each site, with microsite landscape-soil conditions as the most probable driver of this phenomenon. Cluster analysis of individual tree-ring width series based on inter-serial correlation was carried out, resulting in two sub-set chronologies being developed for each site. These chronologies appear to have substantial differences in their climatic responses, mainly during the cold season. This response was not constant due to regional climatic change and the local influence of the nearby Sayano-Shushenskoe Reservoir. The main response of spruce to growing season conditions has a typical elevational pattern expected in mountains: impact of temperature shifts with elevation from positive to negative, and impact of precipitation shifts in the opposite direction. Chronologies of trees, growing under more severe micro-conditions, are very sensitive to temperature during September–April and to precipitation during October–December, and they record both inter-annual and long-term climatic variation. Consequently, it would be interesting to test if they indicate the Siberian High anticyclone, which is the main driver of these climatic factors.
Case of Waardenburg Shah syndrome in a family with review of literature

Waardenburg syndrome is a rare disease characterized by sensorineural deafness in association with pigmentary defects. Depending on additional symptoms, WS have been classified into four types. Waardenburg syndrome type 4, also called as Waardenburg Shah Syndrome is a very rare congenital disorder with astounding variable clinical expression, characterized by pigmentary abnormalities of the hair(A white forelock of hair, premature graying) and pigmentary changes of the iris such as heterochromia or homochromia irides, sensorineural deafness and Hirschsprung disease. Three genes have been bestowed so far in consociation with EDNRB, EDN3, and SOX10 genes. The pattern of inheritance is multifarious with the SOX10 mutation affiliation with autosomal dominant inheritance whereas the EDNRB and EDN3 genes are passed down in an autosomally recessive pattern.

Metastable Phase Equilibrium of the Quaternary System Na~+,Rb~+,Mg~(2+)//Cl~--H_2O at 298.2 K

The component solubilities,densities and refractive indices of the quaternary system Na~+,Rb~+,Mg~(2+)//Cl~--H_2O at 298.2 K were measured using an isothermal evaporation method.Based on the gathered data,a metastable phase diagram,a water content diagram,and a density/refractive index vs.composition diagram were constructed.The results show that this system is of a complex type with a double salt rubidium carnallite (RbCl·MgCl_2·6H_2O) formed at 298.2 K.Double salt rubidium carnallite,whose component point locates in its own crystallization zone in the dry salt phase diagram,belongs to congruent double salt at 298.2 K.Accompanied by the double salt that was formed,there are two invariant points in the phase diagram that cosaturated with three salts and an equilibrated solution.The cosaturated salts for the two invariant points are MgCl_2·6H_2O+RbCl·MgCl_2·6H_2O+ NaCl and NaCl+RbCl+RbCl·MgCl_2·6H_2O,respectively.Both invariant points are commensurate invariant points in the evaporation process,and the two invariant points are evaporative dry points.The sizes of the crystalline regions of the salts are in the order of NaCl>RbCl>RbCl·MgCl_2·6H_2O>MgCl_2·6H_2O.
Ceiling Degree of Polymerization for Brush Polymers Prepared via ROMP of Poly(tert-Butyl Acrylate) Macromonomers

Controlled preparation of brush polymers is important in the design of functional materials.In this study,poly(tert-butyl acrylate) macromonomers functionalized with norbornenyl end group(NB-PtBA) were synthesized via atom transfer radical polymerization in three different molecular weights,2000(NB-PtBA-2k),3000(NB-PtBA-3k),and 8000(NB-PtBA-8k).Additionally,brush polymers with PtBA as side chains were synthesized via ring-opening metathesis polymerization(ROMP).Kinetic studies on ROMP of NB-PtBA showed that there was a ceiling degree of polymerization(CDP) for the brush polymers,beyond which the polymerization of NB-PtBA was out of control.For brush polymers of P[NB-PtBA-2k] and P[NB-PtBA-3k],CDPs were estimated to be ca.400,but the value of P[NB-PtBA-8k] was ca.100.Therefore,the controlled ROMP of brush polymers was critical at the CDP limit with increased macromonomer molecular weight.

[目的]回顾性分析腓骨近端截骨术与人工全膝关节置换术治疗内翻型膝关节骨关节炎的短期临床疗效。[方法]选取2015年1月~2015年10月本院收治的130例内翻型膝关节骨关节炎患者,根据采取手术方案的不同,将患者分为腓骨近端截骨术组(截骨组)与人工全膝关节置换术组(置换组),每组65例。比较两组患者临床资料、治疗效果(总失血量、输血量、手术时间、住院时间、住院期间总花费)、术后并发症及术前、术后3、6个月疼痛视觉模拟评分(VAS)、美国特种外科医院膝关节评分(HSS)和美国膝关节协会评分(KSS)。[结果]所有患者术后随访2年。截骨组在总失血量、输血量、手术时间、住院时间及住院期间总花费等方面明显低于置换组(P< 0.05)。术后两组VAS评分均随着时间的延长而逐渐降低(P<0.05),但组间比较差异无统计学意义(P>0.05)。术后两组HSS、KSS评分均随着时间的延长而逐渐升高(P<0.05),但组间比较差异无统计学意义(P>0.05)。截骨组并发症发生率为6.15%,置换组为7.69%,差异无统计学意义(P>0.05)。[结论]腓骨近端截骨术与人工全膝关节置换术均是治疗内翻型膝关节骨关节炎有效的方法,但腓骨近端截骨术在手术时间、住院时间及住院期间总花费等方面更具优势,值得临床推广应用。
Exploration on Charge Transfer and Absorption Spectra of Spiro[fluorene-9,90-xanthene]-based Polyoxometalate Hybrids Toward High Performance Dye-sensitized Solar Cell

Based on spiro[fluorene-9,90-xanthene](SFX,dye 1),the Lindqvist-type polyoxometalate(POM) functionalized with SFX and its derivatives(dyes 2-4) used in dye-sensitized solar cells(DSSCs) were designed and investigated with the density functional theory(DFT) and time-dependent DFT(TD-DFT) calculations.The results indicate that Lindqvist-type POM is the main contribution to the lowest unoccupied molecular orbital(LUMO) and affects the LUMO energies of dyes 2-4.The maximum absorptions of the designed dyes containing POM(dyes 2-4) are red shifted comparing with that of dye 1.The introduction of electron-donating group onto SFX segment is helpful to red shift the absorption spectra.The major factors affecting the performance of DSSCs,including light harvesting and electron injection were evaluated.Considering the absorption spectra and photovoltaic parameters,dyes 3 and 4 are promising high performance dye sensitizers in n-type DSSCs.

Spatial and Temporal Changes of Wetlands on the Qinghai-Tibetan Plateau from the 1970s to 2010s

Wetlands on the Qinghai-Tibetan Plateau (QTP) perform a dazzling array of vital ecological functions and are one of the most fragile ecosystems in the world. Timely and accurate information describing wetland resources and their changes over time is becoming more important in their protection and conservation. By using remote sensing data, this study intended to investigate spatial distribution and temporal variations of wetlands on the QTP at different watershed scales from 1970s to 2010s. Results show that wetlands on the QTP have undergone widespread degradation from 1970s to 2010s, with nearly 6.4% of their area being lost. Areas of freshwater marsh, salt marsh and wet meadow declined by 46.6%, 53.9% and 15.6%, respectively, while lake area increased by 14.6%. The most extensive losses of natural wetlands have occurred in endorheic basins, such as in the Kunlun-Altun-Qilian Drainage Basin and Qiangtang Basin, which shrank by 44.5% and 33.1%, respectively. A pronounced increase in temperature tends to facilitate the evaporation process and reduce water availability for wetlands. One-third of the wetlands on the QTP are under threat of being submerged due to lakes rising in recent years. More research is needed to gain insight into the interaction mechanisms behind observed variations and potential impacts from further warming in the future.

Forced oscillations and stability analysis of a nonlinear micro-rotating shaft incorporating a non-classical theory

In this paper, the stability and bifurcation analysis of symmetrical and asymmetrical micro-rotating shafts are investigated when the rotational speed is in the vicinity of the critical speed.With the help of Hamilton’s principle, nonlinear equations of motion are derived based on non-classical theories such as the strain gradient theory. In the dynamic modeling, the geometric nonlinearities due to strains, and strain gradients are considered. The bifurcations and steady state solution are compared between the classical theory and the non-classical theories. It is observed that using a non-classical theory has considerable effect in the steady-state response and bifurcations of the system. As a result, under the classical theory, the symmetrical shaft becomes completely stable in the least damping coefficient, while the asymmetrical shaft becomes completely stable in the highest damping coefficient. Under the modified strain gradient theory, the symmetrical shaft becomes completely stable in the least total eccentricity, and under the classical theory the asymmetrical shaft becomes completely stable in the highest total eccentricity. Also, it is shown that by increasing the ratio of the radius of gyration per length scale parameter, the results of the non-classical theory approach those of the classical theory.
Bending of Euler–Bernoulli nanobeams based on the strain-driven and stress-driven nonlocal integralmodels: a numerical approach

Eringen’s nonlocal elasticity theory is extensively employed for the analysis of nanostructures because it is able to capture nanoscale effects. Previous studies have revealed that using the differential form of the strain-driven version of this theory leads to paradoxical results in some cases, such as bending analysis of cantilevers, and recourse must be made to the integral version. In this article, a novel numerical approach is developed for the bending analysis of Euler–Bernoulli nanobeams in the context of strain- and stress-driven integral nonlocal models. This numerical approach is proposed for the direct solution to bypass the difficulties related to converting the integral governing equation into a differential equation. First, the governing equation is derived based on both strain-driven and stress-driven nonlocal models by means of the minimum total potential energy. Also, in each case, the governing equation is obtained in both strong and weak forms. To solve numerically the derived equations, matrix differential and integral operators are constructed based upon the finite difference technique and trapezoidal integration rule. It is shown that the proposed numerical approach can be efficiently applied to the strain-driven nonlocal model with the aim of resolving the mentioned paradoxes. Also, it is able to solve the problem based on the strain-driven model without inconsistencies of the application of this model that are reported in the literature.
导管原位癌样生长方式的转移性乳腺癌临床病理学分析

在转移性乳腺癌中出现类似导管原位癌(ductal carcinoma in situ.DCIS)样结构是十分罕见的.Barsky等把这种现象看作是“真正的DCIS",作为原发肿瘤的转移表型发生逆转的证据.但是被更广泛接受的观点是:这些结构仅仅是模拟DCIS,一部分原来所谓的DCIS实际上可能是一种模拟DCIS样生长方式的浸润性癌.我们回顾了3例DCIS样生长方式的转移性乳腺癌,探讨其临床病理特征,并结合相关文献进行分析,以提高对此类肿瘤的认识.
Pelvi-Femoral Complete Bone Bridge in a Patient with Hemophilia

To the Editor: Heterotopic ossification (HO) is a formation of bone outside of the skeletal system. It usually occurs in the following five broad clinical settings: genetic, posttraumatic, neurogenic, postsurgical and as distinctive reactive lesions most often seen in the hands and feet. Although there is an increased tendency to bleed in soft tissue, HO has rarely been reported in hemophilia. At present, a few cases reported the location relationship between ectopic osteogenesis and the pelvis, and only two cases presented pelvi-femoral bone bridge-like progression of this phenomenon. More precisely, it was situated in the posterior area of the hip joint. Here, we describe a rare case of HO bridging from the anterior superior spine to the lesser trochanter of the femur in hemophilia.
Effect of Ticagrelor on Coronary Blood Flow and Prognosis in Patients with Acute Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention in Real World

To the Editor: Current treatment guidelines for patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) recommend dual antiplatelet therapy, a combination of aspirin and a P2Y12 inhibitor (i.e., clopidogrel, prasugrel, and ticagrelor) for a minimum of 12 months. Ticagrelor, an oral reversibly binding platelet P2Y12 receptor inhibitor, generates a greater and more consistent inhibitory effect with rapid onset of action as compared to clopidogrel. In addition, in vitro and animal experiments demonstrated that ticagrelor might increase the concentration of extracellular adenosine by inhibiting its uptake via red blood cells. Ticagrelor induces an increase in the level of adenosine that produces a series of adenosine-mediated biological effects, such as inhibition of platelet aggregation, relaxation of blood vessels, and protection of heart muscle. The PLATO study showed that ticagrelor reduced the rate of death based on vascular vessels, myocardial infarction (MI), and stroke, without increasing the risk of fatal bleeding in patients with ACS as compared to clopidogrel. A European study found that ticagrelor reduces the risk of mortality, MI, and stroke as compared to clopidogrel in patients with ACS, albeit without increasing the risk of bleeding. These large-scale studies selected patients who were primarily Caucasian. However, a Korean study found that clopidogrel neither reduced the ischemic events nor increased the incidence of bleeding complications as compared to ticagrelor in the East Asian patients with ST-segment-elevated MI (STEMI) and successful revascularization. Does ticagrelor reduce the mortality in patients with STEMI as compared to clopidogrel in the real East Asian world?
Recent Progress in the Construction of Functional Artificial Bone by Cytokine-Controlled Strategies

Objective: Combining artificial scaffolds with stimulatory factors to reconstruct lost bone tissues is one of the hottest research directions. The purpose of this review was to conduct a retrospective survey on the latest reports on artificial bone fabrication with functional cytokines. Data Sources: The status of related scientific research from the year 2005 to 2018 was analyzed through the mode of literature retrieval in PubMed and VIP Database. The retrieval words are as follows: “bone tissue engineering,” “angiogenesis,” “cytokines,” “osteogenesis,” “biomimetic bone marrow,” “sol-gel,” “delivery system,” and the corresponding Chinese words. Study Selection: After reading through the title and abstract for early screening, the full text of relevant studies was evaluated and those not related with this review had been ruled out. Results: According to the literature retrospective survey, there were three key points for the successful construction of functional artificial bones: (1) the continuous supply of relatively low concentration of cytokines during the required period; (2) the delivery of two or more cytokines essential to the process and ensure the relatively spatial independence to reduce the unnecessary interference; and (3) supporting the early-stage angiogenesis and late-stage osteogenesis, respectively, regulating and balancing the crosslinking of both to avoid the surface ossification that would probably block the osteogenesis inside. Conclusions: The synergistic effect of both angiogenic factors and osteogenic factors applied in bone regeneration is a key point in the combined functional artificial bone. Through analysis, comparison, and summary of the current strategies, we proposed that the most promising one is to mimic the natural bone marrow function to facilitate the regeneration process and ensure the efficient repair of large weight-bearing bone defect.
