First published March 27, 2007; doi:10.1152/ajprenal.00057.2007.—Apical low-conductance SK and high-conductance Ca -activated BK channels are present in distal nephron, including the cortical collecting duct (C...

BACKGROUND An optimal therapy for the treatment of pneumonia caused by drug-resistant Acinetobacter baumannii remains unclear. This study aims to compare various antimicrobial strategies and to determine the most effective therapy for pneumonia using a network meta-analysis. METHODS Systematic search and quality assessment were performed to select eligible studies reporting one of the followi...

Results The study group comprised 221 FMF patients (116F, 105M) with a mean age of 12.7±5.3 years. Mean duration of colchicine use was 58.9±45.3 months. Patients were divided into two groups according to their colchicine response; Group I (n=131) included patients with no attacks after colchicine and Group II (n=90) patients with partial or no response to colchicine. Mean age, sex, age at disea...

Type IV collagens (Col IV), components of basement membrane, are essential in the maintenance of tissue integrity and proper function. Alteration of Col IV is related to developmental defects and diseases, including cancer. Col IV α chains form α1α1α2, α3α4α5 and α5α5α6 protomers that further form collagen networks. Despite knowledge on the functions of major Col IV (α1α1α2), little is known wh...

The regular accumulation of nanoparticles in the liver makes them hepatotoxic and decreases the circulation time, thus reducing their therapeutic effect. Resolving this problem will be significant in improving bioavailability and reducing side effects. In this study, we reduced the phagocytosis of epirubicin (EPI)-loaded folic acid-conjugated pullulan acetate (FPA/EPI) nanoparticles by Kupffer ...

Apical low-conductance SK and high-conductance Ca(2+)-activated BK channels are present in distal nephron, including the cortical collecting duct (CCD). Flow-stimulated net K secretion (J(K)) in the CCD is 1) blocked by iberiotoxin, an inhibitor of BK but not SK channels, and 2) associated with an increase in [Ca(2+)](i), leading us to conclude that BK channels mediate flow-stimulated J(K). To ...

The effect of colchicine on stalk elongation in the colonial peritrich ciliate Carchesium sp. has been investigated by growing this protozoon in colchicine-containing media. The length of the stalk in control cultures was 0-4-0-9 mm. In the presence of 2-5-125 mM colchicine, stalk elongation was inhibited, and stalk length was inversely proportional to colchicine concentration. At concentration...

Colchicine was found to have a strong inhibitory effect on amyloid induction in an animal model. When CBA/J mice were treated with colchicine concurrently with the amyloid induction regimen, the incidence of amyloidosis was, depending upon the dosage of colchicine, significantly decreased (0.005-0.010 mg colchicine per day) or completely blocked (more than 0.015 mg colchicine per day). The colc...
