Histophilus somni-induced platelet aggregation was inhibited by antagonists of the platelet-activating factor (PAF) receptor but not inhibitors of PAF synthesis. In addition, H. somni cells expressing phosphorylcholine (ChoP) induced aggregation, while ChoP(-) H. somni cells did not. This suggests that H. somni ChoP may induce platelet aggregation via interactions with the PAF receptor.

The International Prognostic Index (IPI) is a widely accepted model that is used to predict the prognosis of patients with diffuse large B-cell lymphoma (DLBCL) who are treated using chemotherapy. However, the prognostic value of the IPI has been a focal point of debate in the immunochemotherapy era. The aim of this study was to reassess the value of the IPI and revised IPI (R-IPI) in a Chinese...

Hypoxia induced endoplasmic reticulum stress causes accumulation of unfolded proteins in the endoplasmic reticulum and activates the unfolded protein response, resulting in apoptosis through CCAAT-enhancer-binding protein homologous protein (CHOP) activation. In an in vitro and in vivo model of ischemic stroke, we investigated whether hypothermia regulates the unfolded protein response of CHOP ...

BACKGROUND Understanding the bioprocess limitations is critical for the efficient design of biocatalysts to facilitate process feasibility and improve process economics. In this study, a proline hydroxylation process with recombinant Escherichia coli expressing L-proline cis-4-hydroxylase (SmP4H) was investigated. The factors that influencing the metabolism of microbial hosts and process econom...

OBJECTIVE Evaluate the cost-effectiveness of primary vs secondary prophylaxis (PP vs SP) with pegfilgrastim to reduce the risk of febrile neutropenia (FN) in Non-Hodgkin's Lymphoma (NHL) patients receiving myelosuppressive chemotherapy from a US payer perspective. METHODS A Markov model was used to compare PP vs SP with pegfilgrastim in a cohort of patients receiving six cycles of cyclophosph...

To comparatively assess first-line treatment with fludarabine and 2 anthracycline-containing regimens, namely CAP (cyclophosphamide, doxorubicin plus prednisone) and ChOP (cyclophosphamide, vincristine, prednisone plus doxorubicin), in advanced stages of chronic lymphocytic leukemia (CLL), previously untreated patients with stage B or C CLL were randomly allocated to receive 6 monthly courses o...

In this study, 2-aminophenoxazine-3-one (Phx-3) exhibited a potent cell growth inhibitory effect with apoptotic features in a dose-dependent manner in various cancer cell lines tested. Comparison of the expression profiles of endoplasmic reticulum (ER) stress-related genes in U266 multiple myeloma cells after treatment with Phx-3 and the ER stress inducers tunicamycin (TNM) and thapsigargin (TP...

Histophilus somni is a Gram-negative bacterium and member of the Pasteurellaceae that is responsible for respiratory disease and other systemic infections in cattle. One of the bacterium's virulence factors is antigenic phase variation of its lipooligosaccharide (LOS). LOS antigenic variation may occur through variation in composition or structure of glycoses or their substitutions, such as pho...

Objectives: To explore the use of pharmacoeconomic principles through examination of economic evaluations pertaining to the combination of the monoclonal antibody rituximab with conventional CHOP (cyclophosphamide/doxorubicin/ vincristine/prednisone) or CHOP-like chemotherapy regimens in patients with non-Hodgkin lymphoma. Methods: A literature search was conducted using Evidence-Based Medical ...

We conducted a randomized trial to compare the intensive conventional chemotherapy regimen ACVBP (doxorubicin, cyclophosphamide, vindesine, bleomycin, prednisone) with standard CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) in previously untreated patients with poor-risk aggressive lymphoma. Patients aged 61 to 69 years who had aggressive non-Hodgkin lymphoma with at least on...
