BACKGROUND Expression systems based on self-cleavable intein domains allow the generation of recombinant proteins with a C-terminal thioester. This uniquely reactive C-terminus can be used in native chemical ligation reactions to introduce synthetic groups or to immobilize proteins on surfaces and nanoparticles. Unfortunately, common refolding procedures for recombinant proteins that contain di...

Hemorrhagic cystitis is a recognizable complication of cyclophosphamide (CYP) attributable to its lively metabolite acrolein, which produces urothelial injury. The study intended examine the uroprotective efficacy total ginsenosides in Chinese ginseng (TGCG) CYP-induced hemorrhagic cystitis. In total, 24 virgin female rats were randomized into four groups as follows: group 1 (control group; inj...

The systemic use of thiol-containing uroepithelial protecting agents, e.g., N-acetylcysteine (NAC) or mesna, in conjunction with the alkylating agent cyclophosphamide is predicated on the assumption that the toxic metabolic by-products will be consumed by thiol without diminishing the cytotoxicity of the active alkylating intermediate, phosphoramide mustard. Studies in murine tumor systems have...

OBJECTIVE Ovarian adenosarcoma is a very rare tumour for which treatment options vary. We will consider the option of optimal cytoreductive surgery followed by adjuvant chemotherapy consisting of ifosamide (mesna) and adriamycin to prevent systemic metastasis, and will observe the role of serial CA-125 levels as a follow-up marker. CASE REPORT We report a case of ovarian adenosarcoma in a 38-...

Acrolein is a urinary metabolite of cyclophosphamide and ifosfamide, which has been reported to be the causative agent of hemorrhagic cystitis induced by these compounds. A direct cytotoxic effect of acrolein, however, has not yet been demonstrated. In the present study, the effects of intravesical injection of acrolein and mesna, the classical acrolein chemical inhibitor, were evaluated. Male ...

Cyclophosphamide (CP) is metabolized to the reactive intermediates, phosphoramide mustard (PAM) and acrolein (AC), which have generally different molecular binding targets. Sodium 2-mercaptoethanesulfonic acid (MESNA) has been used clinically to alleviate hemorrhagic cystitis caused by CP chemotherapy, has exhibited anticarcinogenic effects in rats exposed to CP during a long-term bioassay, and...

This systematic review aims to synthesize the data on the effectiveness of pharmacological modulation of stress response in minimally invasive surgery. Eligible trials were clinical trials randomized or not or experimental trials that investigated the effect of pharmacological agents on modulation of surgical stress response to minimally invasive surgery. No clinical trials were identified. Eig...

OBJECTIVE To determine the effect of 4-hydroperoxycyclophosphamide (4OOH-CP) on the respiration of human sperm, and investigate the protective properties of mesna and WR-1065. SETTING SUNY Upstate Medical University, Syracuse, NY. PATIENT(S) Men (n = 12) visited the Andrology Department for fertility evaluation. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Sperm respiration. RESULT(S...
