A novel biodegradable diblock copolymer, poly(L-cysteine)-b-poly(L-lactide) (PLC-b-PLLA), was synthesized by ring-opening polymerization (ROP) of N-carboxyanhydride of -benzyloxycarbonyl-L-cysteine (ZLC-NCA) with amino-terminated poly(L-lactide) (NH2-PLLA) as a macroinitiator in a convenient way. The diblock copolymer and its precursor were characterized by 1H NMR, Fourier transform infrared (F...

OBJECTIVE The efficacy and safety of subcutaneous tocilizumab (TCZ-SC) versus subcutaneous placebo (PBO-SC) was evaluated in patients with rheumatoid arthritis who had an inadequate response to disease-modifying antirheumatic drugs in the BREVACTA study. METHODS Patients (n = 656) were randomized 2:1 to receive TCZ-SC 162 mg every other week or PBO-SC every other week for 24 weeks; 20% previo...

Androgen-responsive (SC-3) and -unresponsive (SC-4) cloned cell lines in culture were established from an androgen-responsive mouse mammary tumor, Shionogi carcinoma 115. By using a serum-free medium [Ham's F-12:Eagle's minimum essential medium (1:1, v/v) containing 0.1% bovine serum albumin], characteristics of androgen-induced and autonomous growth factors (GFs) were examined. Serum-free cond...

AIM The α1-antitrypsin-low-density lipoprotein complex (AT-LDL) and serum amyloid A-LDL complex (SAA-LDL) are oxidatively modified LDL complexes that promote atherosclerosis. The serum levels of AT-LDL and SAA-LDL are suggested to be increased by obesity and smoking. We have previously demonstrated that larger weight gain after smoking cessation (SC) perturbs a decrease in the serum level of AT...
