Influence of microalgal N and P composition on wastewater nutrient remediation.

Microalgae have demonstrated the ability to remediate wastewater nutrients efficiently, with methods to further enhance performance through species selection and biomass concentration. This work evaluates a freshwater species remediation characteristics through analysis of internal biomass N:P (nitrogen:phosphorus) and presents a relationship between composition and nutrient uptake ability to assist in species selection. Findings are then translated to an optimal biomass concentration, achieved through immobilisation enabling biomass intensification by modifying bead concentration, for wastewaters of differing nutrient concentrations at hydraulic retention times (HRT) from 3 h to 10 d.

Comparison of initial characteristics and long-term outcome of patients with lymphocyte-predominant Hodgkin lymphoma and classical Hodgkin lymphoma at clinical stages IA and IIA prospectively treated by brief anthracycline-based chemotherapies plus extended high-dose irradiation.

Lymphocyte-predominant Hodgkin lymphoma (LPHL), according to the Revised European-American Lymphoma classification, was considered on a retrospective basis as a specific clinical entity with a large majority of patients at clinical stage (CS) IA or IIA. Of the 500 patients with CS IA/IIA Hodgkin lymphoma (HL) prospectively treated between 1981 and 1996 by one or 3 courses of anthracycline-based chemotherapies combined with high-dose extended irradiation, disease in 42 patients was reclassified as LPHL. These 42 patients, none of whom had mediastinal involvement (MI), were compared with the 458 patients with classical HL (cHL), 144 without MI and 314 with MI.

Three cycles of adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) or epirubicin, bleomycin, vinblastine, and methotrexate (EBVM) plus extended field radiation therapy in early and intermediate Hodgkin disease: 10-year results of a randomized trial.

From 1990 to 1996, a total of 386 adult patients with early/intermediate Hodgkin disease (HD) were randomly assigned to receive 3 cycles of adriamycin, bleomycin, vinblastine, dacarbazine (an alkylating agent), and methylprednisolone (ABVDm, arm A) or epirubicin, bleomycin, vinblastine, methotrexate, and methylprednisolone (EBVMm, arm E), a combination without alkylating agent. Responding patients received extended field radiation therapy (RT). Postchemotherapy complete remission and 10-year freedom from progression rates were higher in arm A (79.

Front-line high-dose therapy with autologous stem cell transplantation for high risk Hodgkin's disease: comparison with combined-modality therapy.

This retrospective study compares high-dose therapy (HDT) with autologous stem cell transplantation and combined-modality treatment (CT) as a first-line therapy for Hodgkin's disease (HD) for patients with both a clinical stage (CS) IV and/or a mediastinal mass > or =0.45 of the thoracic diameter (MM > or =0.45) at diagnosis, and an incomplete response after the first-line chemotherapy.

Long-term complications of total body irradiation in adults.

Purpose: To report long-term pulmonary, thyroid, and ocular complications in patients who had conditioning regimens including total body irradiation (TBI) before bone marrow transplantation (BMT).

Methods And Materials: Between June 1986 and December 1995, 478 patients received TBI in our institution. The present study includes 186 adult patients who had complete remission lasting one year or more after BMT.
