Polarization-controlled anisotropy in hybrid plasmonic nanoparticles.

Anisotropy has played a critical role in many material systems, but its controllable creation and modulation have been a long-lasting challenge for the scientific communities. Polarization-addressed anisotropy appears more attractive among all approaches due to its excellent controllability, simplicity, and accuracy, but only a limited number of material systems are applicable for such a concept, which are largely focused on oriented growth. Here, we establish a polarization-dependent anisotropic etching system made of Au@oligomer core-shell nanoparticles (NPs).

Effects of ectomycorrhizal fungus bolete identity on the community assemblages of endofungal bacteria.

Ectomycorrhiza-associated bacteria, especially endofungal bacterial microbiota (EBM) in the fruiting body, play important roles in driving the establishment and function of ectomycorrhizae. However, the influence of ectomycorrhizal fungus bolete identity on their EBM is still unclear. We analysed the EBM of three different bolete fruiting body species on Thousand Island Lake, including Tylopilus felleus, Tylopilus areolatus and Boletus queletii, and compared them with their corresponding mycosphere soil bacterial microbiota by high-throughput sequencing.

The traditional composting method, adding a microbial agent at one time, has been greatly limited due to its low composting efficiency, mutual influence of microbial agents, and unstable compost products. This study was conducted to assess the effect of multi-phase inoculation on the lignocellulose degradation, enzyme activities, and fungal community during MHRs composting.

Effect of Al alloying on cavitation erosion behavior of TaSi nanocrystalline coatings.

To broaden the scope of non-aerospace applications for titanium-based alloys, both hexagonal C40 binary TaSi and ternary Al alloyed TaSi nanocrystalline coatings were exploited to enhance the cavitation erosion resistance of Ti-6Al-4V alloy in acidic environments. To begin with, the roles of Al addition in influencing the structural stability and mechanical properties of hexagonal C40 Ta(SiAl) compounds were modelled using first-principles calculations. The calculated key parameters, such as Pugh's index (B/G ratio), Poisson's ratio, and Cauchy pressures, indicated that there was a threshold value for Al addition, below which the increase of Al content would render the Ta(SiAl) compounds more ductile, but above which no obvious change would occur.

PET/CT, a standard imaging tool for initial accurate staging and response assessments, has replaced conventional CT in rituximab era. In this review, the definition, interpretation method, prognostic value and risk stratification of interim PET/CT are introduced to clarify the guiding significance of PET/CT in the diagnosis and theray of DLBCL, and the application of PET/CT scanning-guided prognostic factors and response-adapted therapy for DLBCL is summarized.

Emission behaviours of novel V- and X-shaped fluorophores in response to pH and force stimuli.

A family of novel fluorophores with V- and X-shaped skeletons is rationally designed and prepared. Due to the extended cross π-conjugation in the X-shaped ones, their emission wavelengths in both solution and the solid state exhibit considerable bathochromic shifts compared with those of the V-shaped ones. It is found that a heavy intramolecular charge transfer (ICT) effect is the primary element for the mechanofluorochromic (MFC) response of this family, and an appropriate crystallinity of the sample is also indispensible for it to be MFC-active.

[Preliminary discussion on an overview of ethnic minority use of species of mineral medicine].

Sonic Hedgehog Signaling Affected by Promoter Hypermethylation Induces Aberrant Gli2 Expression in Spina Bifida.

GLI2 is a key mediator of the sonic hedgehog (Shh) signaling pathway and plays an important role in neural tube development during vertebrate embryogenesis; however, the role of gli2 in human folate-related neural tube defects remains unclear. In this study, we compared methylation status and polymorphisms of gli2 between spina bifida patients and a control group to explore the underlying mechanisms related to folate deficiency in spina bifida. No single nucleotide polymorphism was found to be significantly different between the two groups, although gli2 methylation levels were significantly increased in spina bifida samples, accompanied by aberrant GLI2 expression.

[Penile rehabilitation after radical pelvic surgery].

Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue.
