Wax has a significant influence on the durability of roofing and pavement. The paper investigated the effects of wax dosages (1%, 3% and 5%) on the performance of bitumen during ultraviolet aging systematically from the macro and micro perspectives. The high-medium-low temperature rheological performance and chemical composition of bitumens were mainly studied, and their light-thermal sensitivity was used by differential scanning calorimetry and ultraviolet spectrophotometer tests, respectively.

Umbilical cord mesenchymal stem cells (UC-MSCs) have emerged as a potential solution to improve graft outcomes. Toll-like receptors (TLRs) play pivotal roles in the immune response, however, their specific functions in UC-MSC-based treatments for corneal graft rejection requires further investigation.

Here we investigated whether blocking the immune checkpoint T cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domains (TIGIT) increases T cell immunity in active Mycobacterium tuberculosis infection. TIGIT expression in both peripheral blood and lung lesions in tuberculosis patients was assessed, and the correlation with clinical features analyzed.

However, following the introduction of rituximab, the prognosis of transformed DLBCL (t-DLBCL) has shown considerable variability across studies. This study aimed to evaluate the outcomes of t-DLBCL originating from HL and indolent B-NHL, and to compare survival rates between t-DLBCL and primary DLBCL (p-DLBCL).

Carbonate rock wettability undergoes substantial alteration under elevated temperatures or asphalt adsorption. To quantitatively assess the impacts of temperature and asphalt on carbonate wettability and analyze its transformation mechanisms, inverse gas chromatography was employed to measure surface energy of Ordovician carbonate samples from Tahe Oilfield across 30-130 °C.

However, whether lactate influences the biogenesis of tumor-derived exosomes (TDEs), the prerequisite for distant metastasis formation, remains unknown. Here, we demonstrated that extracellular lactate, after taken up by tumor cells via lactate transporter MCT1, drove the release of TDE mainly through facilitating multivesicular body (MVB) trafficking towards plasma membrane instead of lysosome.

Previous studies showed that N6-methyladenosine (mA), the most abundant chemical modification in eukaryotic RNAs, is implicated in HCC progression. Using liver-specific conditional knockout mice, we found that the loss of METTL3, the core catalytic subunit of mA methyltransferase, significantly promoted hepatic tumor initiation under various oncogenic challenges, contrary to the previously reported oncogenic role of METTL3 in liver cancer cell lines or xenograft models.

Phycocyanin is a biliprotein that has been used as a natural food colorant due to its brilliant color. However, their application is limited by their poor stability. In this study, biosynthesis pathways of two phycocyanin holo-β subunits, CpcB from mesophilic and CpcB from thermophilic BP-1, were constructed in Coexpression of ferredoxin (Fd), Fd-NADP reductase (FNR), and NADP-specific glutamate dehydrogenase (gdhA) enabled full chromophorylation of these recombinant CpcBs in recombinant .

And their applicability in super-high density UAV-LiDAR point clouds is unknown. Therefore, a 3-D algorithm combining geometric and intensity information from super-high density UAV-LiDAR point clouds is presented.

High-viscosity modified asphalt binder (HVMA) is used widely as a polymer-modified binder in porous asphalt pavement because it can improve the cohesiveness of the asphalt mixture. However, because of the high voidage in the mixture, HVMA is vulnerable to aging induced by temperature, oxygen, water, sunlight, and other climatic conditions, which degrades the performance of pavement. The properties of asphalt binder are affected adversely by the effects of hygrothermal environments in megathermal and rainy areas.

This study employed molecular dynamics (MD) methods to obtain QLL thickness and utilized these measurements to estimate the adhesive strength between ice and asphalt. The research involved constructing an ice-QLL-asphalt MD model, encompassing four asphalt types and five temperature ranges from 250 K to 270 K.

Liver fibrosis is the integral process of chronic liver diseases caused by multiple etiologies and characterized by excessive deposition of extracellular matrix (ECM). During liver fibrosis, hepatic stellate cells (HSCs) transform into a highly proliferative, activated state, producing various cytokines, chemokines, and ECM. However, the precise mechanisms that license HSCs into the highly proliferative state remain unclear.

The metabolic shift from oxidative phosphorylation to glycolysis during ischemia increased glucose consumption and accelerated lactate production. We speculate that donor livers will initiate gluconeogenesis, the reverse process of glycolysis in theory, to convert noncarbohydrate carbon substrates (including lactate) to glucose to reduce the loss of hepatocellular energy and foster glycogen storage for use in the early postoperative period, thus improving post-transplant graft function.

Based on first-principles, we conducted an in-depth study of the GeC/InS van der Waals heterostructure formed by GeC and InS and discussed its structure, electronic properties and optical properties. First, we observe that this heterostructure has negative binding energy, indicating that the interlayer interactions are mainly affected by van der Waals forces. Through band structure and density of state analysis, we confirmed its type-II band alignment characteristics, which means that photogenerated carriers have the ability to automatically separate in space.
