Background: Low volume oral colonoscopy preparations are easier to tolerate and are gaining popularity over large volume oral lavage solutions. Purpose: To compare the efficacy and tolerance of two low volume oral colonoscopy bowel preparations in a prospective randomized single-blinded controll...
The effects of magnesium (Mg) and citrate on the metastable limit of calcium oxalate (CaOx) solubility (synonym: tolerable oxalate TO) were examined in artificial urine and in postprandial urine of male patients with idiopathic calcium urolithiasis (ICU). In artificial urine increasing pH, Mg an...
An efficient procedure for the regioselective synthesis of secondary alcohol alkoxylates from 2,2,4-trimethyl-1,3-pentanediol (TMPD) is described. TMPD was reacted with propylene oxide followed by ethylene oxide in the presence of a catalytic amount of alkali metal hydroxide to form secondary al...
Delirium is a common complication in hospitalized patients and is often associated with significant morbidity. It is important to recognize this syndrome early so that potential causes can be identified and properly managed. Although the etiology of delirium in critically or terminally ill pat...
A new series of sodium barbital complexes with Alkaline earth metals (Mg 2+ , Ca 2+ , Sr 2+ and Ba 2+ ions) was prepared. The molecular formulas for the isolated complexes were suggested basically on the elemental analysis data. The binuclear central were proposed...
In this work, the growth of large size (∼25 × 29 × 5 mm and ∼25 × 24 × 6 mm) colorful single crystals of zinc (tris) thiourea sulfate (ZTS) in the presence of 0.05–2 wt% phenol red (PR) dye was achieved using a simple and low‐cost technique. Powder X‐ray diffraction patterns confirm the...
The (α‐FeOOH) Goethite composite is a stable and an efficient catalyst in aqueous suspension under irradiation at 365 nm and by solar light. The photocatalytic activities of this composite were evaluated using Phenol Red (PR) dye (phenolsulfonphthalein class). In the dark, controlling factors,...
The simultaneous and competitive ultrasound‐assisted removal of naphthol green B (NG‐B) and phenol red (PH‐R) dye from aqueous solutions were rapidly performed onto copper‐doped zinc sulfide nanoparticles loaded on pistachio‐nut shell activated carbon (Zn‐S: Cu‐NPs‐PAC). Novel adsorbent ...
Multidrug resistance (MDR) is one of the major obstacles limiting the efficacy of cancer chemotherapy. Identification of new and effective MDR reversal agents is needed. In this study, the effects of polyoxyethylene 40 stearate (PS40) on MDR were evaluated via the transport of the P-glycoprotein...
Purpose: To assess the chemotherapy regimen of cisplatin, vinblastine, and hydrazine sulfate administered to patients with non-small-cell lung cancer (NSCLC) in a randomized, placebo-controlled double-blind phase III study. Patients and Methods: Between July 25, 1989 and February 1, 1991, 291 pa...
The Pig‐a assay is being used in regulatory studies to evaluate the potential of agents to induce somatic cell gene mutations and an OECD test guideline is under development. A working group involved with establishing the guideline recently noted that representative aneugenic agents had not bee...
Thirty six soil clay samples from surface and subsurface horizons of 18 Thai upland Oxisols and Ultisols under a tropical monsoonal environment were characterized for chemical composition, mineralogy and K release to 0.3M sodium tetraphenylboron (NaTPB) solution for periods up to 168h. The clay ...
. A resonance light scattering technique has been developed in order to determine potassium ion in serum. Potassium ion was found to bind the tetraphenylboronate anion [(C6H5)4B]− in acetate buffer (pH 8.0) in the presence of sodium dodecyl benzene sulfonate as a stabilizer, forming the B(C6H5)4...
The conventional 1 M NH4O Ac-exchangeable potassium (K+) soil test is inadequate in soils where nonexchangeable K+ contributes significantly to crop nutrition. Studies were conducted (i) to compare the abilities of the 1 M NH4O Ac method with a modified NaBPh4 method to estimate critical soil K+...
The four stereoisomers of the 2-hydroxy derivatives of digitoxigenin and 3-epidigitoxigenin have been synthesized, their structures established by NMR, and their binding affinity for the digitalis receptor on Na+, K+-ATPase evaluated. These derivatives showed lower affinities than the parent com...
Cardiac glycosides (CGs) are natural compounds widely used to treat several cardiac conditions and more recently have been recognized as potential antitumor agents. They are known as Na,K-ATPases ligands, which is a promising drug target in cancer. In this study, the short and long-lasting cytot...
Rat peritoneal mast cells were used to study the effects of digitalis glycosides on potassium uptake and histamine release induced by compound 48/80, substance P and egg-albumin (immunological release). In the absence of calcium all glycosides inhibited potassium uptake. Ouabain and digoxin enha...
The present experiments were designed for the development of a liquid chromatographic coupled with tandem mass spectrometric method for the quantitation of trace amount of protoveratrine A in rat plasma. A liquid-liquid extraction protocol was involved in sample preparation. Quantitation was ach...
5β-Methyl-7,8-dihydromorphinone (metopon), an isomer [6a S-(6aα,9aα,10β)13a S]-1,10-methano-4-hydroxy-11-methyl 6,6a,8,9,10,11,12,13-octahydro-[1]-benzopyrano[4,3,e]isoquinoline-7-(9a H)-one (compound 1) derived from a photochemical rearrangement of 5β-methylmorphinone, and [6a S-(6aα,9aα...
The affinity, selectivity and antinociceptive properties of 5β-methyl-14β-(p-chlorocinnamoylamino)-7,8-dihydromorphinone (MET-Cl-CAMO) and N-cyclopropyl-methyl-5β-methyl-14β-(p-chlorocinnamoylamino)-7,8-dihydronor morphinone (N-CPM-MET-Cl-CAMO) for the multiple opioid receptors were characte...
