INTRODUCTION One of the hypotheses regarding the calcification induction by mineral trioxide aggregate (MTA) is the involvement of transforming growth factor-Beta (TGF-β) super family. Calcium-enriched mixture (CEM) cement is one of the endodontic biomaterials with clinical applications similar to MTA. The aim of the present in vitro study was to compare the induction of bone morphogenic protei...

UNLABELLED BACKGROUND Pyrroloquinoline quinone (PQQ), a tricarboxylic acid, has attracted attention as a growth factor, and its application to supplements and cosmetics is underway. The product used for these purposes is a water-soluble salt of PQQ disodium. Although in the past, PQQ disodiumpentahydrates with a high water concentration were used, currently, low hydration crystals of PQQ dis...

BACKGROUND Hypercalcemia of malignancy is a serious complication of cancer that affects patients with and without bone metastases. A single infusion of pamidronate disodium, a nitrogen-containing bisphosphonate, effectively normalizes serum calcium in the majority of patients treated for up to 1 month. Zoledronic acid is a new-generation, heterocyclic nitrogen-containing bisphosphonate and the ...

OBJECTIVE To assess the therapeutic efficacy and toxicity of samarium-153-ethylenediaminetetramethylene phosphonic acid ((153)Sm-EDTMP) and pamidronate disodium in patients with painful metastatic bone cancer. SUBJECTS AND METHODS Eighteen patients with histopathologically confirmed malignancy and multifocal bone metastases were randomized into two equal groups of 9 patients each. Group A was...

PURPOSE To assess the safety and efficacy of gadoxetate disodium-enhanced liver MR imaging in pediatric patients. MATERIAL AND METHODS Retrospective, multicenter study including pediatric patients aged >2 months to <18 years who underwent contrast-enhanced liver MRI due to focal liver lesions. A single intravenous bolus injection of 0.025 to 0.05 mmol/kg body weight of gadoxetate disodium was...

NEW BUFFER SYSTEM has recently been introduced for the separation of proteins (1) and hemoglobins (2) on starch gel. It differs from the conventional barbital system most frequently used heretofore in that the buffer used for the supporting medium differs from that used in the buffer vessels. For this reason the buffer system is referred to as discontinuous. The discontinuous buffer system appe...

Oxygen transport is a primary goal of erythrocytes. The high maintenance of oxygen in erythrocytes defines high speed of formation of active forms of oxygen – superoxide (O2⎯), a hydrogen peroxide (H2O2) and a hydroxyl radical (·OH). A constant source of active forms of oxygen in erythrocytes is hemoglobin oxidation in a methemoglobin with formation of superoxide (O2⎯). Therefore erythrocytes s...

A novel amphiphilic vitamin C derivative, disodium isostearyl 2-O-L-ascorbyl phosphate (VCP-IS-2Na) possessing an alkyl chain of C(18) to a stable ascorbate derivative sodium L-ascorbic acid 2-phosphate (VCP-Na), was synthesized and evaluated as an anti-mutagen with suppressive effect on SOS-inducing activity on mutagen in the Salmonella typhimurium TA1535/pSK1002 umu test. VCP-IS-2Na was assay...

During an acute fall in systemic pH due to a decrease in the concentration of serum bicarbonate ([HCO(3)(-)]), metabolic acidosis, there is an influx of hydrogen ions into the mineral phase of bone, buffering the decrement in pH. When bone is cultured in medium modeling acute metabolic acidosis, the influx of hydrogen ions is coupled to an efflux of sodium and potassium and a depletion of miner...
