PURPOSE The purpose of this study was to investigate the therapeutic and protective effects of molsidomine (MLS) against doxorubicin (DOX)-induced renal damage in rats. METHODS Forty rats were randomly divided into five groups (control, MLS, DOX, DOX+MLS and MLS+DOX groups). Thiobarbituric acid reactive substance (TBARS), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), ...
Objective(s) Doxorubicin (DOX), a widely used chemotherapeutic agent can give rise to serve cardiotoxicity by inducing apoptosis. Curcumin, the active compound of the rhizome of Curcuma longa L. has anti-inflammatory, antioxidant and anti-proliferative activities. Curcumin has been identified to increase cytotoxicity in several cancer cell lines in combination with DOX, but there is no study a...
To enhance effective drug accumulation in drug-resistant tumors, a site-specific drug-releasing polypeptide system (PEG-Phis/Pasp-DOX/CA4) was exploited in response to tumor extracellular and intracellular pH. This system could firstly release the embedded tumor vascular inhibitor (CA4) to transiently 'normalize' vasculature and facilitate drug internalization to tumors efficiently, and then in...
Fluorescence lifetime imaging microscopy (FLIM) has been used to image free and encapsulated doxorubicin (Dox) uptake into cells, since interaction of Dox with DNA leads to a characteristic lifetime change. However, none of the reported Dox conjugates were able to enter cell nuclei. In this work, we use FLIM to show nuclear uptake of 2.7 nm mean diameter Au nanoparticles conjugated to Dox. The ...
Objective: Doxorubicin (DOX) is a broad spectrum chemotherapeutic agent used in the treatment of several malignancies. The use of DOX in clinical chemotherapy has been restricted due to its diverse toxicities, including reproductive toxicity. Crataegus monogyna (C. monogyna) is one of the oldest medicinal plants that have been shown to be cytoprotective because of scavenging free radicals. The ...
We have examined doxorubicin's (DOX) physical state in solution and inside EPC/cholesterol liposomes that were loaded via a transmembrane pH gradient. Using cryogenic electron microscopy (cryo-EM) we noted that DOX loaded to 200-300 mM internal concentrations in citrate containing liposomes formed linear, curved, and circular bundles of fibers with no significant interaction/perturbation of the...
The aim of the study is to determine and compare the pharmacokinetics and tissue distribution of Doxorubicin (Dox) delivered as solution or through nanoparticles after intravenous (i.v.) and intraperitoneal (i.p.) injection. Doxorubicin loaded poly(butyl cyanoacrylate) nanoparticles were synthesized by dispersion polymerization (DP) and emulsion polymerization (EP) techniques. The drug loaded D...
doxorubicin (dox) is an anthracycline antibiotic with broad spectrum anti-tumour activity. its effectiveness has been limited by the occurrence of dose-related myocardial and bone marrow toxicity. as oxidative stress is the main factor in dox-induced cardiotoxicity, we presumed that agents which enhance endogenous antioxidants can prevent dox induced cardiotoxicity. animals received either dox ...
effects of doxycycline on cx43 distribution and cardiac arrhythmia susceptibility of rats after myocardial infarction abstract: this study aimed to observe the effects of doxycycline (dox) on gap junction remodeling after mi and the susceptibility of rats to cardiac arrhythmia. the proximal left anterior descending coronary artery of rats was ligated to establish a myocardial infarction animal ...
زمینه و هدف: داکسوروبیسین (dox)یک داروی ضد سرطان با کاربرد وسیع است که کاربرد بالینی آن در شیمی درمانی به دلیل عوارض جانبی آن از جمله سمیت روی بیضه محدود میشود. هدف از این مطالعه بررسی اثر حفاظتی نانواکسید روی (nzno) بر سمیت القا شده توسط dox در سیستم تناسلی نر میباشد. مواد و روشها: در این مطالعه تجربی رتهای نر بالغ ویستار به طور تصادفی به چهار گروه، شامل گروه کنترل و سه گروه تجربی به ترتیب...
