In our previous rodent studies, the paclitaxel (PTX)-incorporating polymeric micellar nanoparticle formulation NK105 had showed significantly stronger antitumor effects and reduced peripheral neurotoxicity than PTX dissolved in Cremophor® EL and ethanol (PTX/CRE). Thus, to elucidate the mechanisms underlying reduced peripheral neurotoxicity due to NK105, we performed pharmacokinetic analyses of...

Pectenotoxins (PTXs) are a group of lipophilic algal toxins. These toxins have been found in algae and shellfish from Japan, New Zealand, Ireland, Norway and Portugal. PTX profiles vary with geographic location of collection site. The aim of the present study was to investigate PTX profiles from the Yellow Sea, China. The sampling location was within an aquatic farm (N36 degrees 12.428', E120 d...

pervious studies have shown that pentoxifylline (ptx) has beneficial effects in reduction of stroke and brain trauma injuries in experimental animals. however, there is very little and controversial information about the effect of ptx on brain edema in cerebral ischemia. therefore, the aim of this study was to determine the effects of different doses of ptx on brain edema and neurological motor...

Folate receptor (FR) has proven to be a valuable target for chemotherapy using folic acid (FA) conjugates. However, FA-conjugated chemotherapeutics still have low therapeutic efficacy accompanied with side effects, resulting from complications such as short circulation half-life, limited tumor delivery, as well as high kidney accumulation. Herein, we present a novel FA-conjugated paclitaxel (PT...

Pentoxifylline (PTX) has been shown to have beneficial effects on microcirculatory blood flow. In this study we evaluate the potential hemodynamic and metabolic benefits of PTX during hepatic ischemia. We also test the hypothesis that portal PTX infusion can minimize the I/R injury when compared to systemic infusion. Methods. Twenty-four dogs (18.1 ± 0.7 kg) were subjected to portal triad occlu...

Background. We examined the changes in circulating fibroblast growth factor 23 (FGF23) and Klotho concentrations in hemodialysis patients after parathyroidectomy (PTX). Methods. We enrolled a cohort of hemodialysis patients who received PTX. Postoperatively, patients received calcium supplements and/or vitamin D analogue (calcitriol) to maintain serum calcium within 7.0-8.0 mg/dL. Information o...

Purpose: To investigate the role of ischemic preconditioning (IPC) and pentoxifylline (PTX) in intestinal mucosa ischemia/reperfusion injury (IR). Methods: Thirty rats were assigned to 5 groups (N=6): (CG): no clamping of the superior mesenteric artery (90 min.); (IR-SS): saline + ischemia (30 min.) + reperfusion (60 min.); (IR-PTX): PTX + ischemia (30min.) + reperfusion (60 min.); (IPC-IR-S...

Paclitaxel (PTX) is a chemotherapeutic agent that is used to treat a variety of cancers, including non-small cell lung cancer (NSCLC). However, the emergence of drug resistance limits the utility of PTX. This study determined the signaling pathway that contributes to PTX resistance. We first established PTX resistant cell lines (H460/R and 226B/R) using a dose-escalating maintenance of PTX. We ...

Today's mobile, desktop, and server processors are heterogeneous, consisting not only of CPUs but also GPUs other accelerators. Such heterogeneous starting to expose a shared memory interface across these devices.Given that each individual devices typically supports distinct instruction set architecture consistency model, it is clear what the model machine should be. In this paper, we answer qu...

Paclitaxel (PTX) is one of the most effective drugs used in treatment breast cancer. Nonetheless, appearance MDR1 (multidrug resistance 1) tumor cells has become a significant hindrance for efficacious chemotherapy. In this study, we show that expression level Egr-1 (early growth response gene-1) cancer tissues (from paclitaxel chemotherapy failure patients) and MCF-7/PTX (the cell line was res...
