Abstract
Background:
The skeleton is one of the frequent site of metastases in advanced cancer.
Prostate, breast and renal cancers mostly metastasize to bone.
Discussion:
Malignant tumors lead to significant morbidity and mortality. Identification of bone
lesions is a crucial step in diagnosis of disease at early stage, monitoring of disease progression and
evaluation of therapy. Diagnosis of cancer metastases is based on uptake of bone-targeted radioactive
tracer at different bone remodeling sites.
Conclusion:
This manuscript summarizes already established and evolving nuclear medicine modalities
(e.g. bone scan, SPECT, SPECT/CT, PET, PET/CT) for imaging of bone metastases.

Alendronate-Loaded Modified Drug Delivery Lipid Particles Intended for Improved Oral and Topical Administration. Molecules 2016; 21:E858.

Abstract
The present paper focuses on solid lipid particles (SLPs), described in the literature as the most effective lipid drug delivery systems that have been introduced in the last decades, as they actually combine the advantages of polymeric particles, hydrophilic/lipophilic emulsions and liposomes. In the current study, we present our most recent advances in the preparation of alendronate (AL)-loaded SLPs prepared by hot homogenization and ultrasonication using various ratios of a self-emulsifying lipidic mixture of Compritol 888, Gelucire 44/14, and Cremophor A 25. The prepared AL-loaded SLPs were investigated for their physicochemical, morphological and structural characteristics by dynamic light scattering, differential scanning calorimetry, thermogravimetric and powder X-ray diffraction analysis, infrared spectroscopy, optical and scanning electron microscopy. Entrapment efficacy and actual drug content were assessed by a validated HPLC method. In vitro dissolution tests performed in simulated gastro-intestinal fluids and phosphate buffer solution pH 7.4 revealed a prolonged release of AL of 70 h. Additionally, release kinetics analysis showed that both in simulated gastrointestinal fluids and in phosphate buffer solution, AL is released from SLPs based on equal ratios of lipid excipients following zero-order kinetics, which characterizes prolonged-release drug systems.

Enhancement of subchondral bone quality by alendronate administration for the reduction of cartilage degeneration in the early phase of experimental osteoarthritis. Clin Exp Med 2011; 11:235-43. [PMID: 21305336 DOI: 10.1007/s10238-011-0131-z] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2010] [Accepted: 01/14/2011] [Indexed: 01/03/2023]
Abstract
To evaluate the effects of alendronate (ALN) on the subchondral bone quality and cartilage degeneration in the early phase of experimental model of osteoarthritis after anterior cruciate ligament transaction (ACLT). Thirty male adult healthy Japanese white rabbits after right ACLT or sham operation were divided into three groups (n = 10 per group): Sham; ACLT + ALN [after ACLT, the rabbits were treated with ALN daily starting from 4 days after surgery (10 μg/kg/d subcutaneously)]; and ACLT + NS group (after ACLT, the rabbits were injected saline as a placebo). At 60 days postsurgery, specimens from the affected knees were harvested. Histological analysis (HE and Safranin-O staining) as well as Mankin score were carried out to assess the cartilage degradation. BMP-2 and MMP-13 immunohistochemistry were also performed to demonstrate the alterations of cartilage molecular metabolism. Subchondral bone quality was evaluated by bone mineral density (BMD) and microstructure histomorphometry assay. For bone mineral density evaluation, 1/4 distal femurs, medial and lateral regions of femoral condylus were scanned with dual X-ray absorptiometry to assess the subchondral bone mass. Giemsa, von Kossa stain, and fluorescence technique for undecalcified bone section were carried out to examine the morphometry of the subchondral trabecular bone and subchondral plate. Histological and Mankin score analyses displayed that ALN treatment markedly reduced cartilage lesions and delayed the cartilage degeneration in OA joints. Immunohistochemistry assay further indicated that this cartilage-protective role of ALN was associated with elevating BMP-2 while inhibiting MMP-13 expression. BMD assessment demonstrated that ALN treatment significantly suppressed subchondral bone resorption. The results from histomorphometry assay of subchondral bone revealed that ALN treatment markedly increased the percent trabecular area (BV/TV), trabecular thickness (Tb.Th), and trabecular number (Tb.N). Moreover, both thickness and the porosity of the subchondral plate in ACLT + ALN group presented significantly higher than that in ACLT + NS group, while no significant difference was found between ACLT + ALN and Sham group. ALN plays an important role in cartilage protection in OA joints that is associated with the improvement of subchondral bone quality through reduction of subchondral bone resorption. ALN could be potentially used as a disease-modifying strategy to limit the progression of OA.
