Mn-Substituted Tunnel-Type Polyantimonic Acid Confined in a Multidimensional Integrated Architecture Enabling Superfast-Charging Lithium-Ion Battery Anodes.

Given the inherent features of open tunnel-like pyrochlore crystal frameworks and pentavalent antimony species, polyantimonic acid (PAA) is an appealing conversion/alloying-type anode material with fast solid-phase ionic diffusion and multielectron reactions for lithium-ion batteries. Yet, enhancing the electronic conductivity and structural stability are two key issues in exploiting high-rate and long-life PAA-based electrodes. Herein, these challenges are addressed by engineering a novel multidimensional integrated architecture, which consists of 0D Mn-substituted PAA nanocrystals embedded in 1D tubular graphene scrolls that are co-assembled with 2D N-doped graphene sheets.

Ozonated autohemotherapy elevates PPAR-γ expression in CD4 T cells and serum HDL-C levels, a potential immunomodulatory mechanism for treatment of psoriasis.

Psoriasis is widely accepted as a metabolic syndrome with significantly abnormal lipid metabolism and high level of blood lipids that induce a persistent low level of inflammatory condition in patients. T cell mediated immune response plays a critical role in the occurrence and persistence of psoriasis lesions. Hyperlipidemia and associated inflammatory reaction are believed to be the major risk factors for the onset and recurrence of psoriasis.

To address these issues, a three in one strategy using ZrB as the dopant is proposed for constructing a stable Ni-rich cathode. In this strategy, Zr and B are doped into the bulk of LiNiCoMnO, respectively, which is beneficial to stabilize the crystal structure and mitigate the microcracks.

The Beneficial Role of Sunitinib in Tumor Immune Surveillance by Regulating Tumor PD-L1.

Immune checkpoints blockades have shown promising clinical effects in various malignancies, but the overall response rate is low. Here, the immune features are comprehensively characterized in >10 000 cancer patients from The Cancer Genome Atlas and significantly positive correlations are observed between targets of Sunitinib and inhibitory immune checkpoints and suppressive immune cells. It is further confirmed that Sunitinib treatment increases the antitumor immunity in a phase III trial.

Phonon spectrum and thermoelectric properties of square/octagon structure of bismuth monolayer.

First-principles calculation and Boltzmann transport theory have been combined to comparatively investigate the band structure, phonon spectrum, lattice thermal conductivity, electronic transport property, Seebeck coefficient, and figure of merit of square/octagon (s/o)-bismuth monolayer. Calculations reveal that the thermoelectric properties of s/o-bismuth monolayer are better than that of β-bismuth monolayer, which should be mainly due to the low lattice thermal conductivity and weakened coupling of electrons and phonons. It is also found that the phonon frequency and group velocity could play dominant roles in determining the magnitude of the lattice thermal conductivity of s/o-bismuth monolayer.

Highly efficient magnetic labelling allows MRI tracking of the homing of stem cell-derived extracellular vesicles following systemic delivery.

Human stem-cell-derived extracellular vesicles (EVs) are currently being investigated for cell-free therapy in regenerative medicine applications, but the lack of noninvasive imaging methods to track EV homing and uptake in injured tissues has limited the refinement and optimization of the approach. Here, we developed a new labelling strategy to prepare magnetic EVs (magneto-EVs) allowing sensitive yet specific MRI tracking of systemically injected therapeutic EVs. This new labelling strategy relies on the use of 'sticky' magnetic particles, namely superparamagnetic iron oxide (SPIO) nanoparticles coated with polyhistidine tags, to efficiently separate magneto-EVs from unencapsulated SPIO particles.

Bioinformatics analysis reveals the landscape of immune cell infiltration and immune-related pathways participating in the progression of carotid atherosclerotic plaques.

Altered metabolism has been shown to be a prominent pathological change in OA.

CD4 T cell exhaustion leads to adoptive transfer therapy failure which can be prevented by immune checkpoint blockade.

Cytotoxic CD8 T cell exhaustion is one of the mechanisms underlying the tumor immune escape. The paradigm-shifting immune checkpoint therapy can mitigate CD8 T lymphocyte exhaustion, reinvigorate the anticancer immunity, and achieve durable tumor regression for some patients. Emerging evidence indicates that CD4 T lymphocytes also have a critical role in anticancer immunity, either by directly applying cytotoxicity toward cancer cells or as a helper to augment CD8 T cell cytotoxicity.

Lipid droplet and its implication in cancer progression.

Lipid droplets (LDs) are a kind of organelle that is commonly found in eukaryotic cells to store lipids, which encompass a hydrophobic core composed of a single layer of phospholipids and neutral lipids (mainly including triacylglycerol (TAG) and cholesterol ester (CE)) as well as a small amount of proteins. LD accumulation is gradually recognized as a prominent characteristic in a variety of cancers and attracts increasing attention on this field. In this article, we not only summarize the composition, synthesis and decomposition of LD, but also highlight its role in carcinogenesis and malignant development of cancers.

Effect of soil microorganisms and labile C availability on soil respiration in response to litter inputs in forest ecosystems: A meta-analysis.

Litter inputs can influence soil respiration directly through labile C availability and, indirectly, through the activity of soil microorganisms and modifications in soil microclimate; however, their relative contributions and the magnitude of any effect remain poorly understood. We synthesized 66 recently published papers on forest ecosystems using a meta-analysis approach to investigate the effect of litter inputs on soil respiration and the underlying mechanisms involved. Our results showed that litter inputs had a strong positive impact on soil respiration, labile C availability, and the abundance of soil microorganisms, with less of an impact related to soil moisture and temperature.
