l-Phosphinothricin (glufosinate or 2-amino-4-((hydroxy(methyl) phosphinyl) butyric acid ammonium salt (AHPB)), which is a structural analog of glutamate, is a recognized herbicide that acts on weeds through inhibition of glutamine synthetase. Due to the structural similarity between phosphinothricin and some bisphosphonates (BPs), this study focuses on investigating the possibility of repurposi...

Background Camurati-Engelmann disease (CED) is a rare osteosclerotic autosomal dominant condition responsible for chronic diaphyseal pain. It caused by mutations of Tumor Growth Factor β1 (TGFβ1 ) gene. Currently there are no validated therapies this condition. Objectives To test the efficacy anti-TNFα antibody in patient affected CED. Methods Etanercept 50 mg per week was administered with Dat...

A major obstacle in the development of red cell substitutes has been overcoming their short circulation persistence. In this study, distearoyl phosphoethanolamine polyethylene glycol 5000 (PEG-PE) (10 mol%) was added to the formulation of liposome-encapsulated hemoglobin (LEH) to decrease reticuloendothelial system uptake and prolong LEH circulation persistence. PEG-LEH was radiolabeled with te...

BACKGROUND Technetium-labeled agents, which are most often used for assessing myocardial perfusion in myocardial perfusion scintigraphy (MPS), are cleared by the liver and excreted by the biliary system. Spillover from extra-cardiac activity into the myocardium, especially the inferior wall, might conceal defects and lower the diagnostic accuracy of the study. The objective was to determine rul...

HYPOTHESIS Early, postinjection technetium Tc 99m sestamibi scintigraphy-single-photon emission computed tomography (MIBI-SPECT) can be used as the only localizing study for focused parathyroidectomy in patients with primary hyperparathyroidism. DESIGN During a 26-month period, 82 consecutive patients with primary hyperparathyroidism underwent a standard planar scan using a double-tracer subt...

Clinical manifestations of hereditary spherocytosis (HS), the most common red blood cell (RBC) membrane disorder, can be abrogated or markedly reduced by splenectomy. However, concerns regarding risks from overwhelming infections after splenectomy have restricted its use, especially in children. This study was designed to determine if partial splenectomy can decrease the hemolytic rate while ma...

AIM The aim of this study was to assess the degree of alterations of renal function by using 99m-technetium dimercaptosuccinic acid ((99m)Tc-DMSA) and 99m-technetium diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) scintigraphy in spinal cord injury (SCI) patients. MATERIAL AND METHODS Twenty-two consecutive SCI (15 paraplegic and 7 tetraplegic) patients (mean age: 49.1±13.4 years) who had n...

A 27-year-old neurologically disabled but fully conscious male zolpidem-responder patient was investigated for blood brain barrier (BBB) dysfunction 5 years after a traumatic brain injury. A baseline single-photon emission computed tomography (SPECT) technetium-99m-labelled hexamethylpropylene amine oxime (99mTcHMPAO) brain scan was performed and the patient was administered 10 mg zolpidem dail...

Background: Hormesis is defined as the bio-positive response of something which is bio-negative in high doses. In the present study, the effect of radiation hormesis was evaluated on the survival rate of immunosuppressed BALB/c mice by Cyclosporine A.Materials and Methods: We used 75 consanguine, male, BALB/c mice in this experiment. The first group received Technetium-99m (3700Bq) and the seco...
