the utilization of hydroxy sodalite (h-sod) as catalyst under solvent-free condition is described for the efficient preparation of tetrahydrobenzo[b]pyrans. these compounds are synthesized by three-component reactions of aldehydes, alkylnitriles and dimedone. h-sod that is the waste-product of zeolite manufacturing process is used as an efficient and a very inexpensive catalyst. furthermore, it...

BACKGROUND: A study for pain relief therapy with 188Re-HEDP was done in patients with bone metastases secondary to breast and prostate cancer. MATERIALS AND METHODS: Patients received 1.3 or 2.2 GBq, in single or multiple doses. Platelets, white and red cells were evaluated during 11 weeks. Pharmacokinetic characterization was done from blood and urine samples for 5 patients along 24 hours. Uri...

Technetium-99m radiopharmaceuticals play an important role in wide range of applications in nuclear medicine. Bone imaging agents are among the fi rst developed 99mTc-radiopharmaceuticals and the most widely used radiopharmaceuticals in diagnostic nuclear medicine [1]. Bisphosphonates (BPs) are synthetic organic compounds characterized by a P-C-P backbone structure. They are chemically stable a...

Aim Compare efficacy of Dual Rinse HEDP with sodium hypochlorite to in combination a finishing rinse 17% EDTA solution remove the smear layer. Materials and methods Sixteen human maxillary single-rooted, single canalled sound premolars were used. Specimens distributed into 2 groups labeled according irrigation protocol Each group consisted 8 specimens: Group 1 50% NaOCl followed by EDTA. The Ri...

The poor operational stability of electrolytes is a persistent impediment in building redox flow battery technology; choosing suitable additives usually the research direction to solve this problem. effects five phosphate containing (including 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP), hexamethylene diamine tetramethylene phosphonic (HDTMPA), amino trimethylene (ATMPA), sodium ethylenedi...

The potential for laser-produced plasmas to yield fundamental insights into high energy density physics (HEDP) and deliver other useful applications can sometimes be frustrated by uncertainties in modeling the properties behavior of these using radiation-hydrodynamics codes. In an effort overcome this corroborate accuracy HEDP capabilities publicly available FLASH code, we present detailed code...

Introduction: The palliative care in patients with bone metastasis includes variety of techniques such as conventional analgesics, surgery, external beam radiotherapy, hormone therapy, chemotherapy and using bone-seeking radiopharmaceuticals. Even some of the recent works used combined methods like chemotherapy and radionuclide therapy or using radionuclide therapy as adjuvant ...
