Article Abstract
Plant genetic transformation strategies serve as essential tools for the genetic engineering and advanced molecular breeding of plants. However, the complicated operational protocols and low efficiency of current transformation strategies restrict the genetic modification of most plant species. This paper describes the development of the regenerative activity-dependent in planta injection delivery (RAPID) method based on the active regeneration capacity of plants. In this method, Agrobacterium tumefaciens is delivered to plant meristems via injection to induce transfected nascent tissues. Stable transgenic plants can be obtained by subsequent vegetative propagation of the positive nascent tissues. The method was successfully used for transformation of plants with strong regeneration capacity, including different genotypes of sweet potato (Ipomoea batatas), potato (Solanum tuberosum), and bayhops (Ipomoea pes-caprae). Compared with traditional transformation methods, RAPID has a much higher transformation efficiency and shorter duration, and it does not require tissue culture procedures. The RAPID method therefore overcomes the limitations of traditional methods to enable rapid in planta transformation and can be potentially applied to a wide range of plant species that are capable of active regeneration.

Skin scars remain a substantial clinical challenge because of their impact on appearance and psychological well-being. Lysyl oxidases catalyze collagen cross-linking, a key factor in scar development. Here, we report a randomized, double-blind, placebo-controlled phase 1 study to assess the safety and tolerability of PXS-6302, a topical pan-lysyl oxidase inhibitor, in treating mature scars (ACTRN12621001545853).

Photobiomodulation (PBM) therapy involves the use of low-dose, nonionizing light to reduce pain and inflammation, promote wound healing, and enhance tissue regeneration. PBM-based therapy of various dental conditions is associated with improved treatment outcomes. This study aims to critically review the literature to highlight the underlying molecular biological mechanisms and clinical applications of PBM in modern dental practice.

Microbial contamination of absorbable collagen membranes used in guided bone regeneration (GBR) may compromise healing outcomes. This study aimed to investigate whether the minimum inhibitory concentration (MIC) of hydrogen peroxide (HO) can improve the antibacterial effect of indocyanine green (ICG)-mediated antimicrobial photodynamic therapy (PDT) on absorbable collagen membranes while reducing the need for high HO concentrations. A laboratory-based model was developed using Streptococcus sanguinis and Staphylococcus aureus.

Objectives: To investigate the antitumor effects of aucubin (AC) in non-small cell lung cancer (NSCLC) and uncover its plausible mechanism against lung cancer stem-like cells (LCSCs).
Methods: In vitro experiments included MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a reagent commonly used for cell viability assay) and colony formation assays to assess anti-proliferative effects on A549 and NCI-H1975 lung cancer cell lines, wound healing and Transwell invasion assays to evaluate inhibition of cell migration and invasion, tumorsphere-formation experiments to detect changes in NSCLC cell stemness, as well as Western blot and quantitative reverse transcription polymerase chain reaction (qRT-PCR) analyses to measure the expression of LCSC markers (CD44, CD133, Oct4, and Nanog). In vivo experiments were conducted to observe the impact of AC on NSCLC metastasis and mouse survival rates.

Bone defect therapy frequently encounters bacterial infections and chronic inflammation, which impair bone regeneration and threaten implant stability. Iron oxide nanoparticles have attracted attention due to cost-effectiveness, biocompatibility, and metabolic safety. However, iron oxide nanoparticles still struggle to balance low-temperature efficient antibacterial activity, effective immunomodulation, and bone regeneration.
