an experiment with 300 one-day old ross male broiler chicks was conducted to determine the effects of glauconite and zeolite on the broiler's performance, tibia bone and blood characteristics. five experimental treatments [control, glauconite (2 & 4 percent), and zeolite (2 & 4 percent)] were used in a completely randomized design with 4 replicates. during the experiment weight gain, feed ...
Background and purpose: Reconstruction of bone defects remains one of the most challenges encountered by orthopedic and reparative surgeons. The purpose of this study was to assess the osteogenic potential of octacalcium phosphate (OCP) and octacalcium phosphate/gelatin (OCP/G) composite in the tibia bone defects in rats. Materials and methods: This experimental study was conducted in 72 mal...
Background: Understanding the differences in genetics of malignancies is crucial for therapeutic decisions. This systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. Material and Methods: We performed a systematic review of the literature published on genetics of pediatrics bone tumors, using PubMed, Google scholar,...
Background and purpose: Closure of the alveolar cleft using bone grafts is very important in patients with alveolar cleft. Adjunct use of platelet rich fibrin (PRF) with bone graft enhances the bone volume. The aim of the present study was to evaluate the efficacy of grafting by allografts with PRF in stability of bone volume following alveolar cleft grafting using radiographic scales. Mater...
conclusions alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling. results at 6 weeks, the bone area was significantly larger in the xenograft-alendronate group (33.0% ± 5.0%) than in the...
Scenario: The following ECG waveform was obtained in an 85-year-old male patient admitted to the telemetry unit for evaluation of syncope. His pertinent medical history includes hypertension, coronary artery disease, and prior inferior/lateral myocardial infarction (MI). ECG PUZZLER A regular feature of the American Journal of Critical Care, the ECG Puzzler addresses ECG interpretation for clin...

SETTING Participants were recruited from three churches, four public housing developments, and a university teaching hospital-all in the Philadelphia, PA, area. SAMPLE African American adults aged 18-60 years and able to read, writ...
Background: Total bone mass acquired during childhood is known to be the most important determinant and base of lifelong skeletal health. The present study investigated the prevalence of low bone mass for chronological age (LBM) in lumbar and femoral areas of leukemic children in the south of Iran and evaluated the association of anthropometric, clinical and laboratory data of these children ...
