BACKGROUND/PURPOSE Radiotherapy is a crucial treatment for acromegalic patients with growth hormone (GH)-secreting pituitary tumors. However, its effect takes time. We retrospectively reviewed the long-term outcome of linear accelerator stereotactic radiosurgery (LINAC SRS) for patients with acromegaly from the perspective of biochemical remission and(More)
BACKGROUND Liposomal drug packaging is well established as an effective means for increasing drug half-life, sustaining drug activity, and increasing drug efficacy, whether administered locally or distally to the site of disease. However, information regarding the relative effectiveness of peripheral (distal) versus local administration of liposomal(More)
It is the well-known visual secret sharing (VSS) technique that encrypts a secret image into several share images and, later, decrypts the secret by stacking the share images and recognizing by the human visual system. Due to the perfect secrecy, VSS is one of well-candidate for achieving secure e-commerce. Furthermore, the other visual secret sharing(More)
Glioblastoma multiforme (GBM) is a highly malignant brain tumor. The blood-brain barrier (BBB) provides a major obstacle to chemotherapy since therapeutic doses cannot be achieved by traditional drug delivery without severe systemic cytotoxic effects. Recently, microbubble (MB)-enhanced focused ultrasound (FUS) was shown to temporally and locally disrupt(More)
PURPOSE To demonstrate the feasibility of using focused ultrasound to enhance delivery of 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) to glioblastomas in rats with induced tumors and determine if such an approach increases treatment efficacy. MATERIALS AND METHODS All animal experiments were approved by the animal committee and adhered to the experimental(More)
OBJECTIVE Stereotactic biopsy is a widely used surgical technique for the histological diagnosis of intracranial lesions. Potential risks of this procedure, such as hemorrhage, seizure, and infection have been established, and different risk factors have been characterized. However, these risks have been addressed by only few studies conducted in Asian(More)
BACKGROUND Glioblastoma multiforme (GBM) is the most aggressive type of primary brain tumor. It is a rapidly progressive, highly recurrent, fatal intracranial neoplasm, and the demand for novel treatment is urgent. Valproic acid (VPA) is a potential anticancer agent that belongs to a class of histone deacetylase (HDAC) inhibitors, targeting the epigenetic(More)
Recombinant adeno-associated viral (rAAV) vectors are potentially powerful tools for gene therapy of CNS diseases, but their penetration into brain parenchyma is severely limited by the blood-brain barrier (BBB) and current delivery relies on invasive stereotactic injection. Here we evaluate the local, targeted delivery of rAAV vectors into the brains of(More)
PURPOSE To evaluate high-dose-rate (HDR) stereotactic brachytherapy (STBT) for glioblastoma multiforme (GBM). MATERIALS AND METHODS Between August 1994 and December 1998, 28 patients with newly diagnosed GBM underwent surgery, external-beam radiotherapy (EBRT) and HDR STBT. STBT eligibility criteria included unifocal lesions, residual tumor < or = 6 cm in(More)
Next-generation sequencing (NGS) technologies-based transcriptomic profiling method often called RNA-seq has been widely used to study global gene expression, alternative exon usage, new exon discovery, novel transcriptional isoforms and genomic sequence variations. However, this technique also poses many biological and informatics challenges to extracting(More)
