Abstract
We analyzed the disease-specific outcomes of adult ALL treated with cord blood transplantation (CBT) after myeloablative conditioning. Between October 2000 and November 2007, 27 adult patients with ALL were treated with unrelated CBT. All patients received four fractionated 12 Gy TBI and chemotherapy as myeloablative conditioning. The median age was 36 years, the median weight was 57 kg and the median number of nucleated cells was 2.47 x 10(7)/kg. All patients received a single and HLA-mismatched cord blood unit. The cumulative incidence of neutrophil recovery at day 30 and platelet recovery at day 200 was 92.6 and 92.3%, respectively. With a median follow-up of 47 months, the probability of EFS at 5 years was 57.2%. The 5-year cumulative incidence of TRM and relapse was 3.7 and 27.4%, respectively. These results suggest that unrelated CBT after myeloablative conditioning could be safely and effectively used for adult patients with ALL.

Abstract
BACKGROUND Elevated blood pressure (BP) causes rebleeding or enlargement of intracerebral hematomas. AIMS How a long-acting oral calcium channel blocker, cilnidipine, could control BP in the acute stage of cerebral hemorrhage was evaluated. METHODS AND RESULTS Cilnidipine given within 3 days of hospitalization has more benefit than cilnidipine given after 4 days of hospitalization; it can reduce the amount of intravenous nicardipine, and it can help to maintain the BP below 80% of the initial BP. Surgical removal of the hematoma has no benefit in reducing the amount of intravenous nicardipine and maintaining the BP below 80% of the initial BP. CONCLUSION In order to reduce the total amount of intravenous nicardipine and to maintain the BP below 80% of the initial BP, oral administration of a long-acting N-type calcium channel blocker, cilnidipine, is useful and important, independent of whether the hematomas are surgically removed.

Abstract
The incidence of pneumonia caused by Pneumocystis carinii (PCP) (organism now renamed Pneumocystis jiroveci) during the early period after cord blood transplantation (CBT) was studied in 120 adults. Initially 89 patients (74%) received oral administration of 2 single-strength trimethoprim-sulfamethoxazole (TMP-SMZ) tablets twice daily from day -21. In 45 of 89 patients (51%), TMP-SMZ administration for a scheduled duration was completed. In the remaining 44 patients (49%), however, TMP-SMZ administration was discontinued prior to day -3 because of toxicity. Among these patients, 42 subsequently received aerosolized pentamidine (AP) on a median of day -13 (range, -20 to -6). Thirty-one patients (26%) received AP without TMP-SMZ administration on a median of day -14 (range, -21 to -9). None of the 120 patients were diagnosed with PCP within 100 days or 2 years after CBT; however, one patient who received AP before CBT but no prophylaxis after CBT developed cerebral toxoplasmosis on day +91. Pre-transplant prophylaxis against PCP did not significantly affect transplantation-related mortality or disease-free survival at 2 years after CBT. The results suggest that PCP during the early period after CBT can be effectively prevented by any pre-transplant prophylactic method.

Abstract
A computer-assisted analysis identified tentative target sequences for regulatory proteins including ecdysone-inducible factors such as BmFTZ-F1 and Broad-Complex Z4 (BR-C Z4) in the ie1 promoter of BmNPV. A transient expression experiment using BmN cells and a series of truncated ie1 promoter constructs demonstrated that the activity of the ie1 promoter responded to alpha-ecdysone and 20-hydroxyecdysone, which required a tridecameric nucleotide stretch (ie1EcRE, 5'-GTGTTATCGACCT-3') homologous to the ecdysone response element reported for Drosophila (DmEcRE). RT-PCR demonstrated the expression of BmEcR and BmUSP, which are required as ecdysone-specific activators for EcRE-mediated activation, in BmN cells. Furthermore, the ie1 EcRE-mediated response was confirmed by using a recombinant BmNPV possessing a luciferase gene under the control of the ie1 promoter with or without ie1 EcRE. This is the first report of an ecdysone response element in a baculoviral gene promoter. These results also suggested that the regulation of the ie1 by ecdysone may militate viral replication at least under certain conditions during natural infections in vivo.

Abstract
The impact of ABO incompatibility between donor and recipient on engraftment and transfusion requirement was studied in 95 adults who underwent unrelated cord blood transplantation (CBT). The patients included 27 ABO-identical, 29 minor, 21 major and 18 bidirectional ABO-incompatible recipients. Neutrophil engraftment did not differ between ABO-identical/minor ABO-incompatible and major/bidirectional ABO-incompatible recipients (hazard ratio (HR) 1.17, P=0.48). Cumulative incidence of platelet engraftment in ABO-identical/minor ABO-incompatible recipients was higher than in major/bidirectional ABO-incompatible recipients (HR 1.88, P=0.013). In addition, fewer platelet transfusions were required during the first 60 days after CBT in ABO-identical/minor ABO-incompatible recipients (HR 0.80, P=0.040). RBC engraftment did not differ between the two groups (HR 1.25, P=0.33). However, fewer RBC transfusions were required in ABO-identical/minor ABO-incompatible recipients than in major/bidirectional ABO-incompatible recipients (HR 0.74, P<0.005). No patients developed pure red-cell aplasia after CBT. These results indicate that ABO incompatibility affected platelet engraftment and transfusion requirement of RBC and platelet in CBT recipients. Further studies including larger patient numbers are required to elucidate the impact of ABO incompatibility on the clinical outcome of CBT.

Abstract
Glioblastomas are the most common primary brain tumors in adults. These tumors exhibit a high degree of vascularization, and malignant progression from astrocytoma to glioblastoma is often accompanied by increased angiogenesis and the upregulation of vascular endothelial growth factor and its receptors. In this study, we investigated the in vivo antiangiogenic and antitumor effects of brain-specific angiogenesis inhibitor 1 (BAI1) using human glioblastoma cell lines. Glioblastoma cells were transduced with an adenoviral vector encoding BAI1 (AdBAI1), and Northern and Western blot analyses, respectively, demonstrated BAI1 mRNA and protein expression in the transduced tumor cells. Using an in vivo neovascularization assay, we found that angiogenesis surrounding AdBAI1-transduced glioblastoma cells transplanted into transparent skinfold chambers of SCID mice was significantly impaired compared to control treated cells. Additionally, in vivo inoculation with AdBAI1 of established subcutaneous or intracerebral transplanted tumors significantly impaired tumor growth and promoted increased mouse survival. Morphologically, the tumors exhibited signs of impaired angiogenesis, such as extensive necrosis and reduced intratumoral vascular density. Taken together, these data strongly indicate that BAI1 may be an excellent gene therapy candidate for the treatment of brain tumors, especially human glioblastomas.
