Applications of magnetoliposomes with encapsulated doxorubicin for integrated chemotherapy and hyperthermia of rat C6 glioma.

There is substantial evidence regarding enhanced antitumor cytotoxicity of selected chemotherapeutic agents by appropriate heat exposure (40-44°C). Based upon these results, the integration of hyperthermia as an additional treatment modality given simultaneously with systemic chemotherapy is currently of considerable interest. Hyperthermia can be induced by alternating magnetic field and magnetic nanoparticles. Thus, we have used thermosensitive magnetoliposomes that contained superparamagnetic iron oxide ...

Image guided thermosensitive liposomes for focused ultrasound drug delivery: Using NIRF labelled lipids and topotecan to visualise the effects of hyperthermia in tumours.

Image guided drug delivery using imageable thermosensitive liposomes (iTSLs) and high intensity focused ultrasound (FUS or HIFU) has attracted interest as a novel and non-invasive route to targeted delivery of anti-cancer therapeutics. FUS-induced hyperthermia is used as an externally applied "trigger" for the release of a drug cargo from within thermosensitive drug carriers. It is suggested that sub-ablative hyperthermia significantly modifies the permeability of tumour vasculature and enhances nanoparticl...

Direct Quantification of Unencapsulated Doxorubicin in Liposomal Doxorubicin Formulations Using Capillary Electrophoresis.

To understand the quality, efficacy, and safety of liposomal drugs, it is necessary to develop a robust and accurate method for the separation and the quantification of unencapsulated and liposome-associated drugs (or liposomal encapsulated drugs). Conventional methods involve separation of unencapsulated and liposome-associated drug using solid phase extraction and further drug quantification. This is a lengthy process, and sometimes solid phase extraction induces drug leakage from the liposomes causing er...

Effectiveness and Safety of Pegfilgrastim in BEP Treatment for Patients with Germ Cell Tumor.

The effectiveness and safety of pegfilgrastim during bleomycin, etoposide and cisplatin (BEP) chemotherapy have not yet been investigated.

Upregulation of IL-6 is involved in moderate hyperthermia induced proliferation and invasion of hepatocellular carcinoma cells.

Increasing evidences suggested that insufficient radiofrequency ablation (RFA) can paradoxically promote tumor invasion and metastatic processes, while the effects of moderate hyperthermia on cancer progression are not well illustrated. Our present study confirmed moderate hyperthermia treatment can promote the proliferation, migration and invasion of hepatocellular carcinoma (HCC) cells, which was evidenced by the results that moderate hyperthermia induced up regulation of proliferating cell nuclear antige...

To compare the pharmacokinetic bioequivalence and safety of a generic pegylated liposomal doxorubicin formulation (SPIL DXR hydrochloride liposome injection) with that of the reference products, Caelyx or Doxil.

Directed Graphene-Based Nanoplatforms for Hyperthermia-Overcoming Multiple Drug Resistance.

Multidrug resistance (MDR), which leads tumors resistance to traditional anticancer drugs, can cause the failure of chemotherapy treatments. In this work, we present a new way to overcome this problem using smart multifunctional graphene-based drug delivery systems which can target subcellular organelles and show synergistic hyperthermia and chemotherapy. Mitochondria-targeting ligands are conjugated onto the doxorubicin-loaded, polyglycerol-covered nanographene sheets to actively accumulate them inside the...

False-Positive 18F-FDG PET/CT Due to Filgrastim That Induced Extramedullary Liver Hematopoiesis in a Burkitt Lymphoma.

We report a case of Burkitt lymphoma with largely extranodal disease localizations at staging. Chemotherapy was given, thus obtaining a complete metabolic response in all previous disease sites as shown at a control PET, however associated to the appearance of new focal uptake areas in the liver; these findings were confirmed at US and MRI. Chemotherapy determined also neutropenia that was treated by filgrastim, followed by a prompt and important medullary response. Liver biopsy revealed extramedullary hema...

The Effect of Liposome Treatment on Hemorheology and Metabolic Profile of Human Red Blood Cells During Hypothermic Storage.

Ex vivo cold storage of red blood cells (RBCs) for transfusion has long been associated with hypothermic storage lesions. It has been proposed that liposomes can be used to mitigate hemorheological elements of RBC membrane storage lesions. This study aimed to determine the appropriate liposome treatment time and assess the effects of liposome treatment on RBC's hemorheological and metabolic profiles.

Ultrasound Doppler as an Imaging Modality for Selection of Murine 4T1 Breast Tumors for Combination Radiofrequency Hyperthermia and Chemotherapy.

Noninvasive radiofrequency-induced (RF) hyperthermia has been shown to increase the perfusion of chemotherapeutics and nanomaterials through cancer tissue in ectopic and orthotopic murine tumor models. Additionally, mild hyperthermia (37°C-45°C) has previously shown a synergistic anticancer effect when used with standard-of-care chemotherapeutics such as gemcitabine and Abraxane. However, RF hyperthermia treatment schedules remain unoptimized, and the mechanisms of action of hyperthermia and how they chan...

Effect of Pegfilgrastim Primary Prophylactic Administration on Relative Dose Intensity(RDI)in Postoperative Adjuvant Chemotherapy(TC Therapy)for Breast Cancer - A Single-Center, Retrospective Study.

This study assessed the effect of pegfilgrastim in patients with early stage breast cancer who were receiving docetaxel and cyclophosphamide(TC)therapy(75mg/m / 2 docetaxel plus 600 mg/m2 cyclophosphamide). In total, 17 patients who were to receive 4 planned cycles of TC therapy every 3 weeks were included in this study. Of the 17 patients, 10 who received pegfilgrastim after January 2016 formed the Peg-G group and 7 who did not receive pegfilgrastim until December 2015 formed the control group. We observed...

Hyperactivated m-calpain affects acquisition of doxorubicin resistance in breast cancer cells.

Doxorubicin is commonly using chemotherapeutic agents for breast cancer. However, doxorubicin has limitations in clinical use because of dose-dependent cardiotoxicity and drug resistance. Despite of previously reported studies about mechanisms of doxorubicin resistance including overexpression of P-gp and abnormal expression and mutation of topoisomerase IIα, resistance to this agent still abundantly occur and is regarded as a major obstacle to successful treatment.

RFX1 participates in doxorubicin-induced hepatitis B virus reactivation.

Cytotoxic chemotherapy drugs, including doxorubicin, can directly promote hepatitis B virus (HBV) replication, but the mechanism has not been fully clarified. This study investigated the potential mechanism underlying the cytotoxic chemotherapy-mediated direct promotion of HBV replication. We found that HBV replication and regulatory factor X box 1 gene (RFX1) expression were simultaneously promoted by doxorubicin treatment. The amount of RFX1 bound to the HBV enhancer I was significantly increased under do...

Cost-benefit Analysis of Maintaining a Fully Stocked Malignant Hyperthermia Cart versus an Initial Dantrolene Treatment Dose for Maternity Units.

The Malignant Hyperthermia Association of the United States recommends that dantrolene be available for administration within 10 min. One approach to dantrolene availability is a malignant hyperthermia cart, stocked with dantrolene, other drugs, and supplies. However, this may not be of cost benefit for maternity units, where triggering agents are rarely used.

Development of a thermosensitive protein conjugated nanogel for enhanced radio-chemotherapy of cancer.

Although chemo-radiotherapy has been widely applied in clinics for cancer treatment, current strategies still face many challenges including serious side-effects and drug resistance. Herein, we develop a chemically cross-linked poly-N,N'-dimethyl aminoethyl methacrylate (PDMAEMA) smart nanogel as an excellent thermosensitive nanocarrier to load both an anticancer drug, doxorubicin (DOX) and a radioisotope, 131I-labeled albumin, for enhanced chemo-radioisotope therapy. Such a PDMAEMA nanogel in the solution ...

Precise control of the hyperthermia process is imperative for the successful application of such treatment. To that end, this research presents a fast method that enables the estimation of deep tissue heat distribution by capturing and processing the transient temperature at the boundary based on a bio-heat transfer model. The the...

Co-delivery of Doxorubicin and Interferon-gamma by Thermosensitive Nanoparticles for Cancer Immunochemotherapy.

A dual-sensitive nanoparticle delivery system was constructed by incorporating acid sensitive hydrazone linker into thermosensitive nanoparticles (TSNs) for co-encapsulating doxorubicin (DOX) and interferon γ (IFNγ), to realize co-delivery of chemotherapy and immunotherapy agents against melanoma. DOX, a chemotherapeutic drug, was conjugated to TSNs by a pH-sensitive chemical bond and IFNγ, a potent immune-modulator, was absorbed into TSNs through the thermosensitivity and electrostatics of nanoparticles...

Beyond Traditional Hyperthermia. In vivo Cancer Treatment with Magnetic-Responsive Mesoporous Silica Nanocarriers.

This work presents an innovation in the tumor treatment in vivo mediated by magnetic mesoporous silica nanoparticles (MMSNs). This device was built with iron oxide magnetic nanoparticles embedded in a mesoporous silica matrix and coated with an engineered thermoresponsive polymer. The magnetic nanoparticles act as internal heating sources under an alternating magnetic field (AMF) that increase the temperature of the surroundings, provoking the polymer transition and consequently the release of a drug trappe...

Inflammation, edema and poor outcome are associated with hyperthermia in hypertensive intracerebral hemorrhages.

The deleterious effect of hyperthermia on intracerebral hemorrhage (ICH) has been studied, however the results are not completely conclusive and new studies are needed to elucidate clinical factors that condition the poor outcome. The aim of this study was to identify the clinical factors (including ICH etiology) that influence the poor outcome associated with hyperthermia on ICH. We additionally tried to identify potential mechanisms involved in hyperthermia during ICH.

Ultrasound hyperthermia enhances chemo-sensitivity in oral squamous cell carcinoma by TRIF mediated pathway.

Hyperthermia is currently used as an alternative to surgery or in combination with chemotherapy and/or radiation therapy in the treatment of oral squamous cell carcinoma. However, little has been known about the change of chemo-sensitivity after hyperthermia and the mechanism underlie it in oral squamous cell carcinoma.

ETV7-Mediated DNAJC15 Repression Leads to Doxorubicin Resistance in Breast Cancer Cells.

Breast cancer treatment often includes Doxorubicin as adjuvant as well as neoadjuvant chemotherapy. Despite its cytotoxicity, cells can develop drug resistance to Doxorubicin. Uncovering pathways and mechanisms involved in drug resistance is an urgent and critical aim for breast cancer research oriented to improve treatment efficacy. Here we show that Doxorubicin and other chemotherapeutic drugs induce the expression of ETV7, a transcriptional repressor member of ETS family of transcription factors. The ETV...

A photosensitive liposome with NIR light triggered doxorubicin release as a combined photodynamic-chemo therapy system.

The targeted drug delivery with the help of nanocarriers and the controlled drug release at the lesion sites are the most effective ways to enhance therapeutic efficacy and reduce side effects. Here, we built a light sensitive liposome (Her2-I&D-LSL) which was formed by a special phospholipid (PLsPC) and a hydrophobically modified photosensitizer (ICG-ODA). DOX was employed as the therapeutic drug, encapsulating in the internal phase of the liposome whose surface was modified by Her2 antibodies for recogniz...

Bone-targeting liposome formulation of Salvianic acid a accelerates the healing of delayed fracture Union in Mice.

Delayed fracture union is a significant clinical challenge in orthopedic practice. There are few non-surgical therapeutic options for this pathology. To address this challenge, we have developed a bone-targeting liposome (BTL) formulation of salvianic acid A (SAA), a potent bone anabolic agent, for improved treatment of delayed fracture union. Using pyrophosphorylated cholesterol as the targeting ligand, the liposome formulation (SAA-BTL) has demonstrated strong affinity to hydroxyapatite in vitro, and to b...
