In a recent letter, Cui, Duan and Chan propose a generalisation of the Scott-Barreto method to build a larger family of MNT curves, and they claim that their proposal is also applicable to other curve construction methods. Here we show that the Cui-Duan-Chan technique is irrecoverably flawed.

In the present study, two nanoparticles including lactose myristoyl carboxymethyl chitosan (LMCC) and algal polysaccharide myristoyl carboxymethyl chitosan (AMCC), were obtained for hepatic-targeted Adriamycin (ADM) drug delivery systems. ADM was successfully loaded into the LMCC or AMCC nanoparticle by dialysis. The release function and liver targeting of the nanoparticles was explored, and it...

RBT-K5 cell line was established from a male Wistar rat bladder tumor induced with N-butyl-N-(4-hydroxybutyl) nitrosamine. RBT-K5 (ADM res.) cell line, adriamycin (ADM) resistant, was also established from RBT-K5 cells by stepwise escalation of ADM concentrations in vitro. In this study, we have examined the effect of verapamil (VR) on intracellular ADM concentration in these cell lines. The vi...

Adrenomedullin (ADM) acts as an autocrine or a paracrine factor in the regulation of cardiac function. The intracellular mechanisms involved in the direct effect of ADM on adult rat ventricular myocytes (ARVMs) are still to be elucidated. In ARVMs from normal rats, ADM produced an initial (< 30 min) increase in cell shortening and Ca2+ transients and a marked decrease in both on prolonged incub...

We have investigated the tissue distribution of liposome-entrapped Adriamycin (ADM) in mice with metastatic spread to the liver and spleen after inoculation of J-6456 lymphoma cells. Sonicated phosphatidylserine:phosphatidylcholine:cholesterol liposomes were used as carriers of ADM, based on previous studies on the drug entrapment, stability, and tissue distribution of ADM-containing liposomes ...

OBJECTIVE JAK-STAT3 signaling pathway widely participates in cell proliferation and apoptosis. Suppressor of cytokine signaling 3 (SOCS3) is a negative regulator of JAK-STAT3. SOCS3 downregulation is associated with drug resistance in breast cancer and leukemia. However, its role in bladder cancer drug resistance is still unclear. This study established ADM resistant bladder cancer cell model t...

The role of adrenomedullin (ADM) in volume and pressure homeostasis remains undefined. Accordingly, we compared the biological responses to infusions of ADM and nitroprusside (NP; matched for reduction of arterial pressure) and assessed their effects on responses to ANG II and norepinephrine in eight conscious sheep. During matched falls in arterial pressure (8-10 mmHg, both P < 0.001) ADM and ...

OBJECTIVE The main aim of the present study is to examine the electrode configurations used to record the muscle motor evoked potential (mMEP) in the upper extremities during surgery with the goal of producing a high and stable mMEP signal, in particular among the abductor pollicis brevis (APB), abductor digiti minimi (ADM), and across the APB-ADM muscles, which have been widely used for the mM...

Adriamycin (ADM), an anthracycline anticancer agent, is selectively stored in the nuclei of a variety of proliferating cells, but the precise mechanism of specific nuclear transport of ADM is not well known. Recently, we demonstrated that ADM shows high binding affinity to the cytoplasmic proteasomes of L1210 mouse leukemia cells and that taken up ADM by the cells selectively binds to proteasom...

Human adrenomedullin (ADM), a 52-amino acid peptide, belongs to the calcitonin/calcitonin gene-related peptide (CGRP)/amylin peptide family. ADM acts as a multifunctional regulatory peptide and is upregulated in response to hypoxia. Previous microarray studies have found increased ADM gene (ADM) expression in peripheral blood cells of patients with stroke, however, it is unknown if an increased...
