Summary: Polymeric PVA-based composite hydrogels were fabricated with gellan gum (GG) and their rheological and tribological properties were investigated. Increasing the concentration of GG enhanced the storage modulus of the hydrogels, making them suitable for cartilage regeneration applications. Furthermore, the addition of GG reduced the friction coefficient, increasing the chance of survival under mechanical shear stresses.

Summary: Poly(vinyl alcohol) nanofibrous mats containing ad hoc synthesized gold nanostructures were prepared via a single-step electrospinning procedure and investigated for their potential applications. Various shapes and sizes of gold nanostructures were studied for their effects on the physical and chemical properties of the resulting mats. The type of nanostructure was found to influence the mesh morphology of the mats, with different shapes leading to thinner well defined or bigger defect-rich nanofibers.

Summary: In this study, it was discovered that a PDZ-domain-containing protease (Prc) regulated the expression of esrB and T3/T6SSs in different manners at different growth stages. Additionally, Prc mediated the regulation of environmental acidic signals on the expression of esrB. Mutation of esrA impaired E. piscicida virulence expression irrespective of the ambient acidic signals. These findings provide a comprehensive understanding of the virulence regulation upon sensing the environmental acidic signals in bacterial pathogens.

Summary: This paper presents a weakly supervised framework called STC-Seg for instance segmentation and tracking in videos, which utilizes spatio-temporal collaboration. It generates effective pseudo-labels for training deep networks and predicting high-quality instance masks by leveraging the complementary representations from unsupervised depth estimation and optical flow. The framework also enhances mask generation with a puzzle loss and improves robustness to different object appearances through a tracking module that jointly utilizes bounding-box diagonal points with spatio-temporal discrepancy.

Summary: Reasonable selection of process parameters can affect the temperature and flow fields of metal liquid in the mold cavity and achieve the desired casting organization. This study simulated the temperature and flow fields of high molybdenum cast iron casting under different casting temperatures and mold preheating temperatures. The results indicate that casting temperature has a strong impact on the movement state of the metal liquid, while mold preheating temperature influences the solidification rate and cooling time of the casting.

Summary: This research reports the first sensitive and selective fluorescent off-on UGT1A10 probe substrate called UPr6, which can be used to monitor the function of UGT1A10 in biological systems. Through a collaborative modification strategy, the researchers designed UPr6 by introducing a rigid propyl morpholine group and a methoxy group to the amide and 4'-phenoxy positions, respectively. The study also discovered two natural products from licorice as potent UGT1A10 inhibitors, which improved the sensitivity of CPT-11 against a resistant human cancer cell line. This work established a feasible strategy for designing isoform-specific UGT probe substrates.

Summary: In this study, an analytical treatment was conducted to quantitatively evaluate the growth retardation of bainitic transformation (BT) in HSLA steels. By analyzing the thermodynamic driving force ΔG and kinetic energy barrier Q, along with modeling the transformed fraction, unified expressions for thermo-kinetic correlation and generalized stability (GS) were derived. The current model, based on a proposed criterion of high ΔG-high GS, can be used to design the BT to produce bainitic microstructure with high strength and high plasticity, as confirmed by experimental results.
