ZA positively impacts periodontal health, reduces serum inflammation, and enhances bone metabolism in PMO patients with PD.

To address these challenges, we developed polysaccharide hyaluronic acid (HA)-functionalized ruthenium nanoaggregates (Ru NAs) to enhance the chemotherapy of doxorubicin (DOX) for OS. These NAs, comprising Ru nanoparticles (NPs) and alendronate-modified HA (HA-ALN), effectively load DOX, resulting in DOX@Ru-HA-ALN NAs...They can bidirectionally overcome drug resistance of DOX via downregulation of resistance-related factors including multi-drug resistant associate protein, P-glycoprotein, heat shock factor 1, etc. The integration of cascade targeting with bidirectional modulation of drug resistance positions Ru-HA-ALN NAs to substantially enhance DOX chemotherapy for OS. Therefore, the present work highlights the potential of polysaccharide-functionalized nanomaterials in advancing tumor chemotherapy by addressing challenges of both delivery efficiency and drug resistance.

This study concludes with evidence that E2 decreases osteoclast maturation and bone resorption through the regulation of multiple signalling pathways, thereby exhibiting an osteoprotective role in OVX mice. Consequently, E2 exhibits significant potential as a prospective drug candidate for treating osteoporosis.

Indocyanine green (ICG) as a photothermal-transducer ablated tumor cells, zoledronic acid (ZA) depletes TAMs recruited by the inflammatory tumor microenvironment (mostly M2-like phenotype), SB-505124 affects CAFs proliferation in the tumor microenvironment (TME) by inhibiting the transforming growth factor-β （TGF-β） pathway, thereby removing physical barriers to T cell infiltration. In a breast cancer model, these immunomodulatory nanoliposomes markedly decrease the population of M2-like TAMs in the TME, eliminate physical barriers hindering T cell infiltration, reshape the inflammatory immune-suppressive tumor microenvironment, eventually leading to a rate of tumor eradication of 94%. This multifunctional ICG-SB@Lip-ZA nanosystem (including photothermal conversion, TAM depletion, and TGF-β pathway blockade) offers a promising strategy for mitigating the deteriorating tumor microenvironment following PTT and presents a more efficient approach for clinical photothermal-immune combination therapy.

Data on the use of zoledronic acid (ZA) in juvenile CRMO are scarce...The patient's condition stayed stable while taking naproxen (20 mg/kg/day) and methotrexate (10 mg/week) for 1.5 years until he experienced right elbow pain, swelling, no overlying skin erythema, and a restricted range of motion...Non-steroidal anti-inflammatory drugs and methotrexate were initially effective in treating our patient's condition, but a recurrence necessitated treatment modification. To the best of our knowledge, this case is the first documented instance of the use of ZA in CRMO in Iraq and Arab nations.

While the suppressive effect of zoledronate (Zol) on cell viability and migration was observed, the addition of EMD significantly mitigated this effect and enhanced cell viability and migration...This finding suggests that EMD could mitigate the effects of BPs, resulting in the recovery of cell survival, migration, and gene and protein expression. However, the behavior of the osteoblasts was not fully restored, and further studies are necessary to confirm their effects at the cellular level and to assess their clinical usefulness in vivo for the prevention and treatment of MRONJ.

This nanodevice is composed of a dual-pore mesoporous silica core with the capacity to house small cytotoxic drugs, such as doxorubicin or zoledronic acid, and large macromolecules, such as glucose oxidase. Once there, the nanoassemblies also exhibited excellent capacity to induce potent macrophage depletion. This strategy can be directly adapted for the treatment of different malignancies due to the modular nature of the nanoplatform, which can be loaded with different therapeutic agent combinations and pave the way for the development of personalized nanomedicines for diverse types of tumors.

Importantly, the in vivo studies and ki67 and GPX4 staining of tumor sections demonstrated that the ZA@HMNs efficiently accumulated in 4T1 tumors to hinder tumor growth via ZA chemotherapy combined with OH-mediated ferroptosis. This work presents a practicable strategy to fabricate ZA@HMNs for breast tumor-targeted chemo/chemodynamic therapy with potential clinical translation.

Evidence of actual tumor cell elimination, although not significant, was only obtained after preincubation of Mel-RhS with pamidronate, a phosphoantigen-inducing agent, indicating the need for additional T cell receptor-mediated signaling for Vγ9Vδ2-T cells to reach their full oncolytic potential. This study highlights the viability and persistence of Vγ9Vδ2-T cells within the 3D microenvironment, their migratory and antitumor functionality, and the suitability of the model for testing T cell-based therapies, contributing both to the understanding of Vγ9Vδ2-T cell biology and their application in cancer immunotherapy.

This work suggests that TFEB is a gatekeeper of the sensitivity to chemotherapy and immuno-killing in NSCLC, and that the TFEBlowABCA1lowABCC1high phenotype can be predictive of poor response to chemotherapy and immunotherapy. By reshaping both cancer metabolism and tumor immune-microenvironment, zoledronic acid can re-sensitize TFEBlow NSCLCs, highly resistant to chemo- and immunotherapy.

Using Tg(drl:hoxa9) embryos, we performed chemical screening and identified four FDA-approved drugs, ethacrynic acid, khellin, oxcarbazepine, and alendronate, that efficiently restored myeloid differentiation. Thus, the combination of ethacrynic acid and ATRA may have broader clinical applications. In conclusion, through zebrafish-aided screening, our study identified four drugs that can be repurposed to induce AML differentiation, thus providing new agents for AML therapy.
