Intravenous administration of Taxotere® (a commercial form of docetaxel, DTX) leads to many problems such as hypersensitivity, hemolysis, cutaneous allergy, and patient refusal due to its prolonged injection. The oral absorption of DTX is very low due to its hydrophobic nature. The purpose of this study was to prepare and carry out an in vitro evaluation of DTX-loaded nanomicelles for oral admi...
To determine whether the alpha-dendrotoxin (alpha-DTX)-sensitive current [D current, slow inactivating transient current (I(D))] contributes to the modification of neuronal function in small-diameter adult rat trigeminal ganglion (TG) neurons insensitive to 1 microM tetrodotoxin (TTX), we performed two different types of experiments. In the voltage-clamp mode, two distinct K+ current components...
An imbalance of immunosuppressive cells and cytotoxic cells plays an important role in inhibiting the antitumor immune response of the tumor-bearing host. We previously reported the profiles of tumor infiltrating leukocytes in cutaneous angiosarcoma (AS) and suggested that a combination of docetaxel (DTX) with bisphosphonate risedronate sodium (RS) might be effective for MMP9-expressing AS by t...
The homologous Kunitz inhibitor proteins, bovine pancreatic trypsin inhibitor (BPTI) and dendrotoxin I (DTX-I), interact with large conductance Ca2+-activated K+ channels (maxi-KCa) by binding to an intracellular site outside of the pore to produce discrete substate events. In contrast, certain homologues of the Shaker ball peptide produce discrete blocking events by binding within the ion cond...
Battery life is a major issue for any mobile equipment, and reducing energy consumption via energy management in 3G LTE user equipment (UE) will be essential for the delivery of a variety of services. Discontinuous transmission (DTX) and reception (DRX) have been designed to facilitate power management, but they can provide energy savings only via proper tuning. Relevant work in the literature ...
Brain metastasis is a fatal disease with limited treatment options and very short survival. Although systemic chemotherapy has some effect on peripheral metastases of breast cancer, it is ineffective in treating brain metastasis due largely to the blood-brain barrier (BBB). Here we developed a BBB-penetrating amphiphilic polymer-lipid nanoparticle (NP) system that efficiently delivered anti-mit...
In this content, a small molecular ligand of prostate specific membrane antigen (SMLP) conjugated poly (caprolactone) (PCL)-b-poly (ethylene glycol) (PEG) copolymers with different block lengths were synthesized to construct a satisfactory drug delivery system. Four different docetaxel-loaded polymeric micelles (DTX-PMs) were prepared by dialysis with particle sizes less than 60 nm as character...
In this study, dual therapeutic-loaded GE11 peptide-conjugated liposomes were developed and applied to enhance therapeutic efficacies of standard-of-care regimens for the treatment of laryngeal cancer. The therapeutic strategy used here was a combination treatment with the chemotherapeutic docetaxel (DTX) and siRNA against the ABCG2 gene that regulates multidrug resistance in many tumor types. ...
A leading cause of cancer chemotherapy failure is chemoresistance, which often involves multiple mechanisms. Chinese medicines (CM) usually contain multiple components which could potentially target many mechanisms simultaneously and may offer an advantage over single compounds that target one mechanism at a time. The purpose of this study was to investigate the chemosensitizing effect (CE) of ...
Poorly soluble drugs have low bioavailability after oral administration, thereby hindering effective drug delivery. A novel drug-delivery system of docetaxel (DTX)-based stearic acid (SA)-modified Bletilla striata polysaccharides (BSPs) copolymers was successfully developed. Particle size, zeta potential, encapsulation efficiency (EE), and loading capacity (LC) were determined. The DTX release ...
