Proteins are primary targets in drug discovery. However, with a few rare exceptions, they are unable to cross cell membranes, a limitation that prevents the full exploitation of their therapeutic potential. Major advances have been recently made through a novel approach of protein and peptide delivery into cells known as protein transduction or protein therapy. Proteins and peptides can be dire...

MLL (ALL-1) chimeric fusions and MLL partial tandem duplications (PTD) may have mechanistically distinct contributions to leukemogenesis. Acute myeloid leukemia (AML) blasts with the t(9;11)(p22; q23) express MLL-AF9 and MLL wild-type (WT) transcripts, while normal karyotype AML blasts with the MLL(PTD/WT) genotype express MLL PTD but not the MLL WT. Silencing of MLL WT in MLL(PTD/WT) blasts wa...

Preventing massive cell death is an important therapeutic strategy for various injuries and disorders. Protein therapeutics have the advantage of delivering proteins in a short period. We have engineered the antiapoptotic bcl-x gene to generate the super antiapoptotic factor, FNK, with a more powerful cytoprotective activity. In this study, we fused the protein transduction domain (PTD) of the ...

The clinical impact of MLL partial tandem duplication (MLL-PTD) was evaluated in 238 adults aged 18 to 59 years with cytogenetically normal (CN) de novo acute myeloid leukemia (AML) who were treated intensively on similar Cancer and Leukemia Group B protocols 9621 and 19808. Twenty-four (10.1%) patients harbored an MLL-PTD. Of those, 92% achieved complete remission (CR) compared with 83% of pat...

BACKGROUND Major depressive disorders (MDDs) including treatment-resistant depression (TRD) are common disabling conditions, but data on their epidemiology in Japan are limited. This study investigated the incidence, epidemiology, and direct medical costs of TRD and pharmaceutically-treated depression (PTD) in Japan to increase our health economic understanding of this phenotype of MDD. METHO...

Advances in wireless network technology and the continuously increasing users of Personal Trusted Device (PTD) make the latter an ideal channel for offering personalized services to mobile users. In this paper, we apply some cryptology (such as public key infrastructure, hashing chain and digital signature) to propose a realistic mobile ticket system such that fairness, non-repudiation, anonymi...

To evaluate the clinical usefulness of surgical resection of persistent malignant-looking ground-glass-opacity nodules (GGN) without a preoperative tissue diagnosis.From September 1998 to November 2011, we retrospectively enrolled 288 patients (126 men, 162 women; mean age, 59.3 years) with lung adenocarcinoma proven by surgery and which appeared as GGN on chest computed tomography (CT, ground-...

Forkhead box P3 (FOXP3), which is a transcription factor, has a primary role in the development and function of regulatory T cells, and thus contributes to homeostasis of the immune system. A previous study generated a cell-permeable fusion protein of mouse FOXP3 conjugated to a protein transduction domain (PTD-mFOXP3) that successfully blocked differentiation of type 17 T helper cells in vitro...

BACKGROUND The reduction of the preterm delivery (PTD) rate is a maternal and child health target. Elevated rates have been found among several immigrant groups, but few studies have distinguished between PTD according to the mode of birth start. In addition, migrants' birth outcomes have further been shown to be affected by the time in residence; however, the association to PTD subtypes has no...

Advances in wireless network technology and the increasing number of users of Personal Trusted Device (PTD) users make the PTD an ideal channel for offering personalized services to mobile users. In this paper, we propose using a PTD as a payment tool in a mobile transaction system for public transportation. To overcome the inherent weakness of computing resources in a PTD, we use a trusted obs...
