The transcriptional expression pattern of lignocellulolytic enzyme-encoding genes in white-rot fungi differs depending on the culture conditions. Recently, it was shown that 13 putative cellulolytic enzyme-encoding genes were significantly upregulated in most Pleurotus ostreatus ligninolysis-deficient mutant strains on beech wood sawdust medium. However, the mechanisms by which this transcriptional shift is triggered remain unknown. In this study, we identified one mechanism. Our previous study implied that histone H3 N-dimethylation at lysine 4 level possibly affects the shift; therefore, we analysed the expression pattern in the disruptants of P. ostreatus ccl1, which encodes a putative component of the COMPASS complex mediating the methylation. The results showed upregulation of 5 of the 13 cellulolytic enzyme-encoding genes. We also found that rho1b, encoding a putative GTPase regulating signal transduction pathways, was upregulated in the ccl1 disruptants and ligninolysis-deficient strains. Upregulation of at least three of the five cellulolytic enzyme-encoding genes was observed in rho1b-overexpressing strains but not in ccl1/rho1b double-gene disruptants, during the 20-day culture period. These results suggest that Rho1b may be involved in the upregulation of cellulolytic enzyme-encoding genes observed in the ccl1 disruptants. Furthermore, we suggest that Mpk1b, a putative Agaricomycetes-specific mitogen-activated protein kinase, functions downstream of Rho1b.Prevention of metastatic and local-regional recurrence of cancer after surgery remains difficult. Targeting postsurgical premetastatic niche and microresiduals presents an excellent prospective opportunity but is often challenged by poor therapeutic delivery into minimal residual tumors. Here, an enzymatically transformable polymer-based nanotherapeutic approach is presented that exploits matrix metalloproteinase (MMP) overactivation in tumor-associated tissues to guide the codelivery of colchicine (microtubule-disrupting and anti-inflammatory agent) and marimastat (MMP inhibitor). The dePEGylation of polymersomes catalyzed by MMPs not only exposes the guanidine moiety to improve tissue/cell-targeting/retention to increase bioavailability, but also differentially releases marimastat and colchicine to engage their extracellular (MMPs) and intracellular (microtubules) targets of action, respectively. In primary tumors/overt metastases, the vasculature-specific targeting of nanotherapeutics can function synchronously with the enhanced permeability and retention effect to deter malignant progression of metastatic breast cancer. After the surgical removal of large primary tumors, nanotherapeutic agents are localized in the premetastatic niche and at the site of the postsurgical wound, disrupting the premetastatic microenvironment and eliminating microresiduals, which radically reduces metastatic and local-regional recurrence. The findings suggest that nanotherapeutics can safely widen the therapeutic window to resuscitate colchicine and MMP inhibitors for other inflammatory disorders.Based on the form-invariance of Maxwell’s equations under coordinate transformations, mathematically smooth deformation of space can be physically equivalent to inhomogeneous and anisotropic electromagnetic (EM) medium (called a transformation medium). It provides a geometric recipe to control EM waves at will. A series of examples of achieving transformation media by artificially structured units from conventional materials is summarized here. Such concepts are firstly implemented for EM waves, and then extended to other wave dynamics, such as elastic waves, acoustic waves, surface water waves, and even stationary fields. These shall be cataloged as transformation metamaterials. In addition, it might be conceptually attractive and practically useful to control diverse waves for multi-physics designs.

Vonoprazan has more potent and sustained acid inhibitory effects than proton pump inhibitors; therefore, Helicobacter pylori eradication rates are expected to improve with the use of vonoprazan-based regimens. 3-Amino-9-ethylcarbazole in vivo To date, no randomized trial has compared the efficacy of 7-day vonoprazan-based triple therapy (7-VAC) with 14-day omeprazole-based triple therapy (14-OAC). This study aimed to compare the H.pylori eradication rates of 7-VAC and 14-OAC.

This randomized clinical trial was performed at a tertiary hospital in Bangkok. Patients with active H.pylori infection who were naive to treatment were included and randomized (11) into either a 7-VAC group (vonoprazan 20mg bid. pc., amoxicillin 1000mg bid. pc., and clarithromycin 500mg bid. pc.) or a 14-OAC group (omeprazole 20mg bid. ac., amoxicillin 1000mg bid. pc., and clarithromycin 500mg bid. pc.). Eradication success was evaluated by urea breath test 4-6weeks after completion of treatment.

A total of 122 subjects were randomized to receive 7-VAC (n=61) or 14-OAC (n=61). The H.pylori eradication rates of the 7-VAC and 14-OAC groups were 96.7% and 88.5% (P=0.083), respectively, by intention-to-treat analysis and 98.3% and 93.1% (P=0.159), respectively, by per-protocol analysis. All treatment-related adverse events were mild and not significantly different between the two groups. Common side effects included bitter taste, nausea, and dizziness.

The 7-VAC regimen was well tolerated and achieved similar eradication rates and side effects to those of 14-OAC; therefore, 7-VAC may be considered an alternative regimen for H.pylori treatment with the benefit of shorter duration.

Plasticity-related genes (Prgs/PRGs) or lipid phosphate phosphatase-related proteins (LPPRs) comprise five known members, which have been linked to neuronal differentiation processes, such as neurite outgrowth, axonal branching, or dendritic spine formation. PRGs are highly brain-specific and belong to the lipid phosphate phosphatases (LPPs) superfamily, which influence lipid metabolism by dephosphorylation of bioactive lipids. PRGs, however, do not possess enzymatic activity, but modify lipid metabolism in a way that is still under investigation.

We analyzed mRNA expression levels of all Prgs during mouse brain development, in the hippocampus, neocortex, olfactory bulbs, and cerebellum. We found different spatio-temporal expression patterns for each of the Prgs, and identified a high expression of the uncharacterized Prg4 throughout brain development. Unlike its close family members PRG3 and PRG5, PRG4 did not induce filopodial outgrowth in non-neuronal cell lines, and does not localize to the plasma membrane of filopodia.

We showed PRG4 to be highly expressed in the developing and the adult brain, suggesting that it is of vital importance for normal brain function. Despite its similarities to other family members, it seems not to be involved in changes of cell morphology; instead, it is more likely to be associated with intracellular signaling.

This qualitative study was an integral part in the development of a multidisciplinary team-led school-based human papillomavirus vaccination health-promotion programme (MDL-SHPVP) aiming to increase HPV vaccine uptake in Hong Kong. Study findings will inform the design of the MDL-SHPVP by drawing on interview data regarding the expectations and needs of key stakeholders and potential programme users.

Eight mother-daughter dyads, four secondary school teachers, two school principals, three social workers and one school nurse were interviewed. All interviews were audio-recorded and transcribed verbatim for thematic analysis.

Most participants had misconceptions about HPV and the vaccine. Alhough there was no immediate perceived need for the vaccination, most participants had favourable attitudes towards HPV inoculation and vaccines in general. Factors affecting vaccine uptake included perceptions about risk of infection, vaccine availability, and cost. Participants were largely open to suggested MDL-SHPVP components (videos, digital game, and group discussions).

Findings have highlighted knowledge gaps among potential users and key stakeholders and will be used to inform the design of the MDL-SHPVP to ensure that their needs and expectations are addressed. Study findings may also aid future HPV vaccine promotion efforts and boost HPV vaccine uptake among youth in the city.

To pursue the objective, a simple self-assembly strategy is developed to access carbon superstructures built of nanoparticle embedded plates. The carbon precursors, 2,4,6-trichloro-1,3,5-triazine and 2,6-diaminoanthraquinone can form porous organic polymer with “protic salt”-type rigid skeleton linked by -NH2 + Cl- – “rivets”, which provides the cornerstone for hydrogen-bonding-guided self-assembly of the organic backbone to superstructures by π-π plane stacking. The ameliorative charge density distribution and decreased adsorption energy in as-fabricated carbon superstructures allow the high accessibility of the build-in protophilic sites and efficient ion diffusion with a low energy barrier. Such superstructures thus deliver ultra-stable charge storage and fast proton-coupled kinetics at the structural-chemical defects, contributing to unprecedented lifespan (1 000 000 cycles), high-rate capability (100 A g-1 ) for carbon-based supercapacitors, and an ultrahigh energy density (128 Wh kg-1 ) for Zn-ion hybrid supercapacitors. The self-assembled carbon superstructures significantly improve the all-round electrochemical performances, and hold great promise for efficient energy storage.Although immunotherapy such as immune checkpoint inhibitors has shown promising efficacy in cancer treatment, the responsiveness among patients is relatively limited. Activation of the cyclic guanosine monophosphate-adenosine monophosphate synthase/interferon gene stimulator (cGAS/STING) signaling pathway to upregulate innate immunity has become an emerging strategy for enhancing tumor immunotherapy. Herein, ZnS@BSA (bovine serum albumin) nanoclusters synthesized via a self-assembly approach are reported, where the released zinc ions under acidic tumor microenvironment significantly enhance cGAS/STING signals. Meanwhile, intracellular zinc ions can produce reactive oxygen species, which is further facilitated by the generated H2 S gas from ZnS@BSA via specifically inhibiting catalase in hepatocellular carcinoma cells. It is found that the nanoclusters activate the cGAS/STING signals in mice, which promotes the infiltration of CD8+ T cells at the tumor site and cross-presentation of dendritic cells, leading to an improved immunotherapy efficacy against hepatocellular carcinoma.
