    Description: 〈span〉〈div〉Abstract〈/div〉Pre-drill pore pressure prediction is essential for safe and efficient drilling, and is a key element in the risk-reducing toolbox when designing a well. On the Norwegian Continental Shelf, pore pressure prediction commonly relies on traditional 1D offset well analysis, whereas velocity data from seismic surveys are often not considered. Our work with seismic interval velocities shows that the velocity field can provide an important basis for pressure prediction and enable the construction of regional 3D pressure cubes. This may increase the confidence in the pore pressure models and aid the pre-drill geohazard screening process. We demonstrate how a 3D velocity field can be converted to a 3D pore pressure cube using reported pressures in offset wells as calibration points. The method is applied to a regional dataset at the Halten Terrace in the Norwegian Sea; an area with a complex pattern of pore pressure anomalies which traditionally has been difficult to predict. The algorithm is searching for a velocity to pore pressure transform that best matches the reported pressures. The 3D velocity field is a proxy of rock velocity and is derived from seismic surveys, and is verified to checkshot velocities and sonic data in the offset wells.〈/span〉

    Description: In this work, we investigate the generalized Hyers-Ulam stability of the Apollonius type additive functional equation in modular spaces with or without Δ 2 -conditions. We study the same problem in fuzzy Banach spaces and β -homogeneous Banach spaces. We show the hyperstability of the functional equation associated with the Jordan triple product in fuzzy Banach algebras. The obtained results can be applied to differential and integral equations with kernels of non-power types.

    Description: In a phase I study, the sequentially administered combination of recombinant human interleukin-3 (rhIL-3) and rhGM-CSF was compared with treatment with rhIL-3 alone in 15 patients with advanced tumors but normal hematopoiesis. Patients were initially treated with rhIL-3 for 15 days. After a treatment-free interval, the patients received a second 5-day cycle of rhIL-3 at an identical dosage, immediately followed by a 10-day course of rhGM-CSF, to assess the toxicity and biologic effects of this sequential rhIL-3/rhGM-CSF combination. rhIL-3 doses tested were 125, and 250 micrograms/m2, whereas rhGM-CSF was administered at a daily dosage of 250 micrograms/m2. Both cytokines were administered by subcutaneous (SC) bolus injection. rhIL-3/rhGM-CSF treatment was more effective than rhIL-3 but equally effective to each other in increasing peripheral leukocyte counts, especially neutrophilic and eosinophilic granulocyte counts. In contrast, both modes of cytokine therapy raised the platelet counts to the same degree. rhIL-3/GM-CSF treatment was more effective than rhIL-3 in increasing the number of circulating hematopoietic progenitor cells BFU- E and CFU-GM. High-dose rhIL-3, but not low-dose rhIL-3, was as effective as the rhIL-3/rhGM-CSF combinations in increasing the number of circulating CFU-GEMM. The increase in absolute neutrophil counts correlated with the increase in the number of circulating CFU-GM. Side effects, mainly fever, headache, flushing, and sweating, were generally mild, but in two patients the occurrence of chills, rigor, and dyspnea after initiation of GM-CSF treatment necessitated dose reduction and discontinuation, respectively. These results indicate that sequential treatment with rhIL-3 and rhGM-CSF is as effective as single-factor treatment with rhIL-3 in stimulating platelet counts, whereas the effect of combination therapy on neutrophil counts and circulating progenitor cells is superior.

    Description: This prospective multicenter study examined whether simultaneous administration of granulocyte colony-stimulating factor (G-CSF; Filgrastim) and induction chemotherapy for adult acute lymphoblastic leukemia (ALL) could prevent treatment-related neutropenia, infections, and resulting treatment delays. Seventy-six patients were randomly assigned to receive either G-CSF (n = 37) or no growth factor (n = 39) in conjunction with a uniform chemotherapy consisting of cyclophosphamide, cytarabine, mercaptopurine, intrathecal methotrexate, and cranial irradiation. The median duration of neutropenia (absolute neutrophil count 〈 1 x 10(9)/L) during chemotherapy was 8 days in patients receiving C-CSF, compared with 12.5 days in the control group (P 〈 .002). A similar reduction from 11.5 to 7 days was observed in patients with T-ALL receiving additional mediastinal irradiation (P = .13). Infections occurred in 43% and 56% of patients in the G-CSF and control arm, respectively (P = .25); the incidence of nonviral infections was reduced by 50%, from 32 episodes in the control arm to 16 episodes in the G-CSF arm. Prolonged interruptions of chemotherapy administration were less frequent, with delays of 2 weeks or more occurring in only 24% of patients receiving G-CSF as opposed to 46% in the control arm (P = .01). Accordingly, chemotherapy was completed significantly earlier with the use of G-CSF (39 v 44 days, P = .008). With a median follow-up of 20 months, the probability of disease-free survival was 0.45 in the G-CSF group and 0.43 in the control group (P = .34). In conclusion, adult ALL patients appear to benefit by the simultaneous administration of G-CSF with induction chemotherapy because of a significant reduction in the duration of neutropenia, a trend to fewer infections, and a more rapid completion of chemotherapy.

    Description: In a phase I/II study, nine patients with aplastic anemia were treated with recombinant human interleukin-3 (rhIL-3) to assess the toxicity and biologic effects of this multipotential hematopoietic growth factor. Doses ranging from 250 micrograms/m2 to 500 micrograms/m2 were administered as subcutaneous bolus injections daily for 15 days. An increase in platelet counts from 1,000/microL to 31,000/microL was induced by rhIL-3 in one patient, and an increase in reticulocyte counts by more than 10,000/microL in four patients. The blood leukocyte counts temporarily increased in eight patients 1.5- to 3.3-fold (median, 1.8-fold), mainly due to an increase in the number of neutrophils, eosinophils, lymphocytes, and monocytes. In two patients, bone marrow cellularity increased from 7% to 33% and from 10% to 80%, respectively, but without resulting in a substantial improvement of peripheral blood counts. Mild side effects (headache and flushing) were observed in some patients, while low-grade fever occurred in all patients. Transient thrombocytopenia necessitating discontinuation of rhIL-3 treatment occurred in one patient. In conclusion, rhIL-3 can stimulate hematopoiesis in patients with aplastic anemia; however, no lasting effects were obtained.

    Description: To develop a sensitive and specific assay for minimal residual disease in acute lymphoblastic leukemia (ALL), we exploited the enormous diversity of genomic sequences created by immune receptor gene rearrangements. To isolate clone-specific sequences, we first synthesized oligonucleotides that match conserved variable (VH) and joining (JH) sequences flanking the third hypervariable region (HVR3) in the rearranged immunoglobulin heavy chain (IgH) locus. In polymerase chain reactions (PCR), these primers were then used to amplify the intervening HVR3 segments from leukemic DNA samples. Of 12 B-lineage ALLs studied, ten generated one or more fragments of the size expected for HVR3 gene segments. Thus, this single pair of amplimers was sufficient to isolate HVR3 sequences from a majority of acute lymphoblastic leukemias. To verify that the amplified fragments originated from HVR3 alleles and to assess their diversity, we sequenced 7 PCR products derived from 6 leukemias. In addition to elements of recognized D segments, each of the 7 fragments contained novel VH-D and D-JH junctional sequences, including N nucleotides, not known to be present in the germline. Each sequence was unique, and allele-specific oligonucleotide probes hybridized only to HVR3 segments from which the probes were derived. Therefore, as anticipated, these HVR3 segments appeared to possess the diversity required to serve as clonal markers for leukemic populations. To demonstrate that these amplified HVR3 alleles could serve as the basis for a sensitive and specific assay to detect rare leukemic cells, we analyzed in detail one pre-B leukemia that had rearranged 2 IgH alleles. The HVR3 sequences were shown to be linked to rearranged JH-containing restriction fragments in digests of genomic DNA, establishing their origin in the leukemic cells. We synthesized oligonucleotides corresponding to the unique junctional sequences in the HVR3 segments. Using these novel amplimers in an allele-specific amplification and hybridization procedure, we showed that this assay can detect 10 leukemic cells in a background of 10(6) normal blood mononuclear cells. In contrast, the leukemic HVR3 sequences were not detected in extracts of normal or unrelated remission leukemic leukocytes. We conclude that the assay for specific IgH HVR3 sequences is a realistic strategy for detection of minimal residual disease in B-lineage ALL.
