The purine nucleoside analogues clofarabine and fludarabine are active in acute myeloid leukemia (AML). We conducted a phase I/II randomized study of idarubicin and cytarabine with either clofarabine (CIA) or fludarabine (FIA) for relapsed or refractory AML. Clofarabine 15 mg/m(2) was identified as the recommended phase II dose. Eighty-one patients were assigned using adaptive randomization to CIA (n = 48) or FIA (n = 33). The complete response (CR)/CR without platelet recovery rate did not differ between CIA and FIA (38% versus 30%, respectively; p = ...

Recently, microsomal prostaglandin E synthase 1 (mPGES-1) has attracted much attention from pharmacologists as a promising strategy and an attractive target for treating various types of diseases including rheumatoid arthritis (RA), which could preserve the anti-inflammatory effect while reducing the adverse effects often occur during administration of Non-steroidal anti-inflammatory drugs (NSAIDs). Here, we report that Sinomenine (SIN) decreased prostaglandin (PG)E2 levels without affecting prostacyclin (PG)I2 and thromboxane (TX)A2 synthesis via selective inhibiting mPGES-1 expression, a possible reason of low risk of cardiovascular event compared with NSAIDs...

BACKGROUND: Biological therapies are common in the treatment of patients with chronic inflammatory arthritis (CIA). However, despite the fact that many patients respond well to their biological therapies, there are still a number of nonresponders. In order to design the best care for patients, it is important to understand how they conceive their own role in their treatment response. OBJECTIVE: To explore how patients with CIA conceive their own influence on a good treatment response to biological therapy...

Cognitive impairment associated with schizophrenia (CIAS) is highly prevalent and affects the overall functioning of patients. Clozapine (Clz), an atypical antipsychotic drug, significantly improves CIAS although the underlying mechanisms remain under study. The role of the 5-HT1A receptor (5-HT1A-R) in the ability of Clz to prevent the learning/memory impairment induced by MK-801 was investigated using the modified elevated plus-maze (mEPM) considering the Transfer latency (TL) as an index of spatial memory...

INTRODUCTION: Re-interventions are still the Achilles' heel of endovascular aneurysm repair (EVAR). Ectatic common iliac arteries (CIA) can be treated with flared iliac limbs but a dilated artery used as sealing zone could increase the risk of a late type 1b endoleak. The aim of the present analysis was to evaluate the risk of late type 1b endoleak after EVAR in patients with CIA limbs ≥20 mm compared with those <20 mm. METHODS: A retrospective analysis was performed of patients treated by EVAR at the study institution between 2006 and 2012, including patients with available information about the type of iliac stent grafts and a minimum follow-up (FU) of 3 years with contrast enhanced CT, or those that had developed a type 1b endoleak earlier...

IK can downregulate interferon (IFN)-γ-induced major histocompatibility complex (MHC) class II expression through the MHC class II transactivator, which suggests that IK can inhibit the interactions between immune cells. We delivered adeno-associated virus serotype 2 (AAV2) encoding the genes for truncated IK (tIK) or green fluorescent protein (GFP) to DBA1/J mice via intravenous injection. Seven weeks after injection, collagen-induced arthritis (CIA) was induced in the AAV2 treated mice. AAV2-tIK injection reduced the severity of arthritis and the percentage of pathogenic Th17 cells compared with AAV2-GFP injection...

Affinity chromatography based on amino acids as interacting ligands was already indicated as an alternative compared to ion exchange or hydrophobic interaction for plasmid DNA purification. Understanding the recognition mechanisms occurring between histidine-based ligands and nucleic acids enables more efficient purification of a DNA vaccine, as the binding and elution conditions can be adjusted in order to enhance the purification performance. Decreasing pH to slightly acidic conditions increases the positive charge of histidine ligand, what influences the type of interaction between chromatographic support and analytes...

Adipose tissue is an organ that performs a lot of significant physiological functions, which is why its excess in the body results in pathological states in many of its organs and systems. Adipose tissue is not only a tissue which stores fat and plays a protective role. It is an important endocrine organ where signals sent from different tissues are generated and integrated. Adipose tissue is both morphologically and physiologically differentiated. However, due to their plasticity, adipocytes can undergo a transformation and change their structure and metabolism depending on the physiological state of the organism and the conditions to which it is exposed...

Dipeptidyl peptidase I (DPPI), a lysosomal cysteine protease, required for activation of serine proteases of granulocytes including mast cells (MCs), neutrophils (NPs) and others, which were found in synovial tissue of patients with rheumatoid arthritis (RA). But, the role of DPPI associated with those cells in RA development is unclear. In this study, the collagen-induced-arthritis (CIA) rat-model was employed to investigate the expression and activity levels of DPPI and its association with RA progress. Primary granulocytes were freshly extracted from bone-marrows of normal or CIA rats, human mast cell line LAD-2 and primary neutrophils, human-recombinant-DPPI, DPPI-inhibitor Gly-Phe-CHN2 , LTB4, anti-IgE antibody, calcium ionophore were used to study the regulatory role of DPPI in cell activations...
