The pincer ligand 2,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-methoxy-1,3,5-triazine (bpmt) was used to synthesize the novel [Na(bpmt)2][AuCl4] complex through self-assembly method. In this complex, Na(I) ion is hexa-coordinated with two tridentate N-pincer ligands (bpmt). bpmt units are meridionally coordinated via one short Na-N(s-triazine) and slightly longer Na-N(pyrazole) bonds, resulting in a...

Onpi-to, an herbal medicine composed of five crude drugs (Rhei Rhizoma, Glycyrrhizae Radix, Ginseng Radix, Zingiberis Rhizoma and Aconiti Tuber), was administered orally to rats. Onpi-to includes 1.240% of total potential rhein derived from sennoside A, sennoside B, rhein 8-O-glucopyranoside and rhein. Plasma, urinary and biliary levels of rhein were determined by an HPLC-UV method. The plasma ...

Rickettsia rickettsii infection of endothelial cells is manifested in very distinctive changes in cell morphology, consisting of extensive dilatation of the membranes of the endoplasmic reticulum and outer nuclear envelope and blebbing of the plasma membrane, as seen by transmission electron microscopy (D. J. Silverman, Infect. Immun. 44:545-553, 1984). These changes in cellular architecture ar...

Ro 17-2301 (AMA-1080) is a new N-sulfonated monocyclic beta-lactam that is highly active against gram-negative bacteria, especially against Enterobacteriaceae and Haemophilus, Neisseria, and Pseudomonas spp. (Kondo et al., Proc. Int. Congr. Chemother. 13th, Vienna, Austria, p. 56/1-56/5, 1983). The single-dose pharmacokinetics of this compound were studied in six healthy male volunteers who rec...

bioequivalence study is a scientific and practical method used to compare the quality of a generic drug with a reference product. this study aimed to examine the bioequivalence of two closantel formulations produced with different sources of raw material by a domestic pharmaceutical company. due to long half- life of closantel, the study carried out by a parallel method. thirty sheep were divid...

The toxicity of Xanthorrhoea johnsonii methanolic leaf extract was investigated using the Artemia franciscana nauplii bioassay. At 24 h, the extract produced an EC(50) of 361.0 ± 41.8 μg/ml, indicating that it was substantially more toxic than the pesticide Mevinphos (1346.2 ± 80.1 μg/ml) and approximately 4 fold less toxic than potassium dichromate (87.1 ± 5.2 μg/ml). Whilst potassium dichroma...

In this study, we investigated the effect of savory (Satureja hortensis) essential oil, garlic(Allium sativum) powder, and garlic aqueous extract on fungal load of poultry feed. Tothis end, savory essential oil and garlic aqueous extract each amounting 62.5, 125, and250 μl/ml and mg/ml, respectively, per kilogram of feed and garlic powder amounting2.5, 5, and 10 g/kg of feed were used. One and ...

Thirty postpubertal Holstein heifers were used to investigate the influence of dietary intake on 1) serum concentrations of progesterone (P4) and luteinizing hormone (LH) during diestrus and 2) estrous behavior. Heifers were randomly allotted to receive either 80, 100 or 120% of the National Research Council (NRC) requirements for energy, protein and dry matter intake for 139 d. Heifers were fe...

Target drug deliveries using nanotechnology are a novel consideration in the treatment of cancer. We present herein an in vitro mouse model for the preliminary investigation of the efficacy of an iron oxide nanoparticle complex conjugated to vascular endothelial growth factor (VEGF) antibody and ligand cluster of differentiation 80 (CD80) for the purpose of eventual translational applications i...

BACKGROUND Total thyroidectomy (TT) is a commonly performed surgery and postoperative hypocalcemia is a major detriment to early discharge. The aim of this randomized controlled trial was to ascertain the usefulness of routine pre- and post-operative calcium and Vitamin D supplementation in prevention of hypocalcemia after TT. MATERIALS AND METHODS Sixty consecutive patients who underwent tot...
