OBJECTIVE
To investigate the isolated and combined effects of compression and hypoxia on the osteoclastogenesis induced by periodontal ligament cells (PDLCs).
METHODS
A periodontal ligament tissue model (PDLtm) was established by 3-D culturing human PDLCs on a thin sheet of poly lactic-co-glycolic
Oxygen deficiency resulting from bone fracture-induced vascular disruption leads to massive cell death and delayed osteoblast differentiation, ultimately impairing new bone formation and fracture healing. Enhancing local tissue oxygenation can help promote bone regeneration. In this work, an
Hypoxia is an inseparable component of the solid tumor as well as the bone marrow microenvironment. In this study, we investigated the effect of the novel polyethylene glycol (PEG)-poly L-lysine (PLL)-poly lactic-co-glycolic acid (PLGA) based nanoparticles (NPs) modified by transferrin (Tf) loaded
The effective delivery of antioxidants to the cells is hindered by their high metabolization rate. In this work, quercetin was encapsulated in poly(lactic-co-glycolic) acid (PLGA) nanoparticles. They were characterized in terms of its physicochemical properties (particle size distribution,
The proliferation of pulmonary arterial smooth muscle cells (PASMCs) is a key pathophysiological component of vascular remodeling in pulmonary arterial hypertension (PAH), an intractable disease, for which pharmacotherapy is limited and only slight improvement in survival outcomes have achieved over
The present study is an attempt to leverage therapeutic benefits of curcumin in pulmonary hypertension by encapsulating it in biodegradable poly(lactide-co-glycolic) acid nanoparticles. Pulmonary hypertension is induced in experimental animals by subjecting them to chronic hypoxic conditions. The
The regeneration capacity of osteoporotic bones is generally lower than that of normal bones. Current methods of osteoporotic bone defect treatment are not always satisfactory. Recent studies demonstrate that activation of the hypoxia inducible factor-1α (HIF-1α) pathway, by genetic methods or
MicroRNAs (miRs) are frequently overexpressed in human cancers. In particular, miR-210 is induced in hypoxic cells and acts to orchestrate the adaptation of tumor cells to hypoxia. Silencing oncogenic miRs such as miR-210 may therefore offer a promising approach to anticancer therapy. We have
Currently, there is no effective long-term treatment for intervertebral disc (IVD) degeneration, making it an attractive candidate for regenerative therapies. Hydrogel delivery of adipose stem cells (ASCs) in combination with controlled release of bioactive molecules is a promising approach to halt
Tamoxifen-based hormone therapy is central for the treatment of estrogen receptor positive (ER+ ) breast cancer. However, the acquired tamoxifen resistance, typically co-exists with hypoxia, remains a major challenge. We aimed to develop a non-invasive, targeted ultrasound imaging
The practice of treating PAH patients with oral or intravenous sildenafil suffers from the limitations of short dosing intervals, peripheral vasodilation, unwanted side effects, and restricted use in pediatric patients. In this study, we sought to test the hypothesis that inhalable
Hepatocellular carcinoma (HCC) is a malignant tumor characterized by easy metastasis and frequent recurrence. Transarterial chemoembolization (TACE) remains the routine treatment for patients with HCC who are not eligible for surgical resection or percutaneous tumor ablation; however, 5-year
While nitric oxide (NO) can remedy vasoconstriction, inhalation of NO may cause systematic toxicity. We report a goldsome, which comprises a hollowed poly(lactic-co-glycolic acid) (PLGA) polymersome with S-nitrosoglutathione (GSNO, a NO donor) molecules and gold nanoparticles (Au NPs) incorporated
Affected by environmental factors such as oxygen deficiency, the secretion of growth factor was abnormal in bone injury sites, resulting in the poor responses of osteoblasts and prolonging the healing process. Herein, in this study, we reported an in situ oxygen-releasing porous titanium coating
Chlorine exposure can lead to pulmonary obstruction, reactive airway dysfunction syndrome, acute respiratory distress syndrome and, rarely, death.We performed a systematic review of published animal and human data regarding the management of chlorine
