A cancer-associated microbiome is considered a carcinogen capable of affecting tumor initiation and/or progression. However, little is known about the molecular mechanisms of tumor-microbiome interactions. Here, we show that Staphylococcus sciuri promotes Drosophila intestinal tumor growth by inducing intestinal stem cell (ISC) division.

Serum samples were collected up to 168 h post-dosing and analyzed using a validated HPLC-MS/MS method. Contrary to conventional expectations, ENR absorption was delayed and elimination was slower at 22°C compared to 13°C, while the plasma concentrations of CIP were higher at the elevated temperature.

In vitro tests with isolated adult parasites demonstrated that ABZ exhibited the highest efficacy, followed by FBZ, while MBZ showed minimal activity and FB remained largely inactive at lower concentrations. At the highest concentration tested (200 mg/L), FB showed only weak, nonspecific activity.

In addition, the effects of combined temperature and salinity on their growth and fatty acid contents were examined to evaluate the value as potential source for commercial application. Morphological observations indicated that there were no critical differences in the morphologies of both isolates, and molecular phylogeny based on LSU rRNA gene sequences revealed that the two isolates are nested within ribotype A of A.

A key challenge in flexible optoelectronics is developing transparent electrodes (TEs) with high optical and electrical performance that can survive deformation. Here, silver-based TEs with anti-reflection coatings (STEAR) are developed and demonstrate a sheet resistance of 8.9 Ω/sq, 85% transmittance (including the substrate), and stability over 16,000 bending cycles.

We collected 230 vision sentences from 85 Korean hospitals in 2024 through their websites. Major frequent words in visions were "Hospital," "Healthcare," "Lead," "Center," "Treatment," "Trust," "Patient," "Research," "Best," and "Customer" counted over 15 times.

By integrating the Conservation of Resources theory and Role Theory, we seek to provide a more comprehensive understanding of how negative customer interactions affect employee well-being beyond the immediate work setting.
Methods: We conducted a two-wave, time-lagged survey among 586 full-time service sector employees in South Korea.
Seawater electrolysis is a promising approach for sustainable and environmentally friendly hydrogen production, primarily because it has zero carbon emissions and mitigates freshwater resource scarcity. However, seawater electrolysis requires high selectivities for both the oxygen and hydrogen evolution reactions in an environment characterized by a high concentration of impurity ions, particularly Cl. In addition, the corrosion resistance of materials to byproducts is essential.

Performance pressure is a pervasive organizational force with complex implications for employee behavior. Grounded in Conservation of Resources (COR) theory, this study examines how performance pressure influences unethical pro-organizational behavior (UPB) through the mediating role of job strain while also considering the moderating effect of perceived coworker support. Using survey data from 280 police officers, our findings demonstrate that performance pressure significantly increases UPB, with job strain serving as a key explanatory mechanism.

Despite official approval for select species, off-label use is common. This study evaluated the antibacterial efficacy and residue depletion of AMOX in five aquaculture species: olive flounder (), rainbow trout (), Japanese eel (), black rockfish (), and Israeli carp ().
View Article and Find Full Text PDFLithium (Li) metal has received significant attention as an anode material for next-generation batteries due to its high theoretical capacity and low redox potential. However, the high reactivity of Li metal leads to the formation of a native layer on its surface, inducing nonuniform Li flux at the electrolyte/Li metal interface, which promotes the growth of Li metal dendrites. In this study, perfluorooctyltriethoxysilane (PFOTES) was vaporized to chemically react with the native layer and modify the Li metal surface.

Serum and tissue (muscle, liver and kidney) samples were collected at pre-determined time points and analysed using high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). The results demonstrated that temperature significantly influenced the PK parameters of OA.

Here we show that microbiome-emitted scents contain volatile somatotrophic factors (VSFs), which promote host growth in an olfaction-independent manner in Drosophila. We found that inhaled VSFs are readily sensed by olfactory receptor 42b non-neuronally expressed in subsets of tracheal airway cells, enteroendocrine cells, and enterocytes.

Here, we show that paraspeckle component 1 (PSPC1) is aberrantly overexpressed and associated with poor survival in AML patients. Using human AML cells and mouse models, we demonstrate that PSPC1 is not required for normal hematopoiesis, but it is critical and essential for AML cells to maintain their leukemic characteristics.

Single-crystal cathodes have been investigated for their inherent resistance to intergranular cracking due to the absence of grain boundaries. However, these materials exhibit significant intragranular cracking, and the underlying mechanisms remain unclear. In this study, we examined the impact of extended solid-solution reactions on mitigating crack formation in magnesium-doped single-crystal LiNiMnO (Mg-SC-LNMO) cathodes.

Osteoclastogenesis, the formation of osteoclasts, is primarily driven by NFATc1, a process activated through c-Fos and NF-κB signaling pathways in response to receptor activator of nuclear factor κB ligand (RANKL). Dysregulation of RANKL signaling is a key contributor to pathological bone loss, as seen in conditions such as osteoporosis.

The detoxification process of transforming arsenite (As(III)) to arsenate (As(V)) through bacterial oxidation presents a potent approach for bioremediation of arsenic-polluted soils in abandoned mines. In this study, twelve indigenous arsenic-oxidizing bacteria (AOB) were isolated from arsenic-contaminated soils. Among these, Paenibacillus xylanexedens EBC-SK As2 (MF928871) and Ochrobactrum anthropi EBC-SK As11 (MF928880) were identified as the most effective arsenic-oxidizing isolates.

Aggregation of misfolded amyloid-β (Aβ) and hyperphosphorylated tau proteins to plaques and tangles, respectively, is the major drug target of Alzheimer's disease (AD), as the former is an onset biomarker and the latter is associated with neurodegeneration. Thus, we report a small molecule drug candidate, DN5355, with a dual-targeting function toward aggregates of both Aβ and tau. DN5355 was selected through a series of four screenings assessing 52 chemicals for their functions to inhibit and reverse the aggregation of Aβ and tau by utilizing thioflavin T.
