Silica-based nanoarchitecture for an optimal combination of photothermal and chemodynamic therapy functions

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 12,   Pages 2144-2155 doi: 10.1007/s11705-023-2362-4

Abstract: This study introduces multifunctional silica nanoparticles that exhibit both high photothermal and chemodynamic therapeutic activities, in addition to luminescence. The activity of the silica nanoparticles is derived from their plasmonic properties, which are a result of infusing the silica nanoparticles with multiple Cu2–xS cores. This infusion process is facilitated by a recoating of the silica nanoparticles with a cationic surfactant. The key factors that enable the internal incorporation of the Cu2–xS cores and the external deposition of red-emitting carbon dots are identified. The Cu2–xS cores within the silica nanoparticles exhibit both self-boosting generation of reactive oxygen species and high photothermal conversion efficacy, which are essential for photothermal and chemodynamic activities. The silica nanoparticles’ small size (no more than 70 nm) and high colloidal stability are prerequisites for their cell internalization. The internalization of the red-emitting silica nanoparticles within cells is visualized using fluorescence microscopy techniques. The chemodynamic activity of the silica nanoparticles is associated with their dark cytotoxicity, and the mechanisms of cell death are evaluated using an apoptotic assay. The photothermal activity of the silica nanoparticles is demonstrated by significant cell death under near-infrared (1064 nm) irradiation.

Long noncoding RNA LOC646029 functions as a ceRNA to suppress ovarian cancer progression through the

Frontiers of Medicine   Pages 924-938 doi: 10.1007/s11684-023-1004-z

Abstract: Long noncoding RNAs (lncRNAs) play a crucial regulatory role in the development and progression of multiple cancers. However, the potential mechanism by which lncRNAs affect the recurrence and metastasis of ovarian cancer remains unclear. In the current study, the lncRNA LOC646029 was markedly downregulated in metastatic ovarian tumors compared with primary tumors. Gain- and loss-of-function assays demonstrated that LOC646029 inhibits the proliferation, invasiveness, and metastasis of ovarian cancer cells in vivo and in vitro. Moreover, the downregulation of LOC646029 in metastatic ovarian tumors was strongly correlated with poor prognosis. Mechanistically, LOC646029 served as a miR-627-3p sponge to promote the expression of Sprouty-related EVH1 domain-containing protein 1, which is necessary for suppressing tumor metastasis and inhibiting KRAS signaling. Collectively, our results demonstrated that LOC646029 is involved in the progression and metastasis of ovarian cancer, which may be a potential prognostic biomarker.

The use of Artificial Neural Networks to estimate seismic damage and derive vulnerability functions for

Tiago Miguel FERREIRA, João ESTÊVÃO, Rui MAIO, Romeu VICENTE

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 3,   Pages 609-622 doi: 10.1007/s11709-020-0623-6

Abstract: This paper discusses the adoption of Artificial Intelligence-based techniques to estimate seismic damage, not with the goal of replacing existing approaches, but as a mean to improve the precision of empirical methods. For such, damage data collected in the aftermath of the 1998 Azores earthquake (Portugal) is used to develop a comparative analysis between damage grades obtained resorting to a classic damage formulation and an innovative approach based on Artificial Neural Networks (ANNs). The analysis is carried out on the basis of a vulnerability index computed with a hybrid seismic vulnerability assessment methodology, which is subsequently used as input to both approaches. The results obtained are then compared with real post-earthquake damage observation and critically discussed taking into account the level of adjustment achieved by each approach. Finally, a computer routine that uses the ANN as an approximation function is developed and applied to derive a new vulnerability curve expression. In general terms, the ANN developed in this study allowed to obtain much better approximations than those achieved with the original vulnerability approach, which has revealed to be quite non-conservative. Similarly, the proposed vulnerability curve expression was found to provide a more accurate damage prediction than the traditional analytical expressions.

Evidence for lung repair and regeneration in humans: key stem cells and therapeutic functions of fibroblast

Xuran Chu, Chengshui Chen, Chaolei Chen, Jin-San Zhang, Saverio Bellusci, Xiaokun Li

Frontiers of Medicine 2020, Volume 14, Issue 3,   Pages 262-272 doi: 10.1007/s11684-019-0717-5

Abstract: Regeneration carries the idea of regrowing partially or completely a missing organ. Repair, on the other hand, allows restoring the function of an existing but failing organ. The recognition that human lungs can both repair and regenerate is quite novel, the concept has not been widely used to treat patients. We present evidence that the human adult lung does repair and regenerate and introduce different ways to harness this power. Various types of lung stem cells are capable of proliferating and differentiating upon injury driving the repair/regeneration process. Injury models, primarily in mice, combined with lineage tracing studies, have allowed the identification of these important cells. Some of these cells, such as basal cells, broncho-alveolar stem cells, and alveolar type 2 cells, rely on fibroblast growth factor (FGF) signaling for their survival, proliferation and/or differentiation. While pre-clinical studies have shown the therapeutic benefits of FGFs, a recent clinical trial for acute respiratory distress syndrome (ARDS) using intravenous injection of FGF7 did not report the expected beneficial effects. We discuss the potential reasons for these negative results and propose the rationale for new approaches for future clinical trials, such as delivery of FGFs to the damaged lungs through efficient inhalation systems, which may be more promising than systemic exposure to FGFs. While this change in the administration route presents a challenge, the therapeutic promises displayed by FGFs are worth the effort.
