Mode of action of herbicidal derivatives of aminomethylenebisphosphonic acid. I. Physiologic activity and inhibition of anthocyanin biosynthesis
1996
N-Pyridylaminomethylenebisphosphonic acids constitute a class of promising herbicides. Since their mode of action at the cellular level is still poorly understood, we studied the influence of N-pyridylaminomethylenebisphosphonic acids on plant growth, at the whole plant and undifferentiated tissue levels, using seedlings and cell suspension cultures of mono- and dicotyledonous species. These compounds exhibited strong herbicidal properties, being equipotent with the popular herbicide glyphosate. Since they also depressed buckweed anthocyanin biosynthesis, the shikimate pathway could represent a site of action of N-pyridylaminomethylenebisphosphonic acids.
Nonexposed Variant of Bisphosphonate-associated Osteonecrosis of the Jaw: A Case Series
2010
Abstract Purpose To report a case series of patients with the nonexposed variant of bisphosphonate-associated osteonecrosis of the jaw—a form of jaw osteonecrosis that does not manifest with necrotic bone exposure/mucosal fenestration. Methods Among 332 individuals referred to 5 clinical centers in Europe because of development of jawbone abnormalities after or during exposure to bisphosphonates, we identified a total of 96 patients who presented with the nonexposed variant of osteonecrosis. Relevant data were obtained via clinical notes; radiological investigations; patients' history, and referral letters. Results The most common clinical feature of nonexposed osteonecrosis was jaw bone pa…

Criteria for the prescription of oral bisphosphonates for the treatment of osteoporosis in a series of women referred for tooth extraction
2012
Objective: To evaluate the criteria for the prescription of oral bisphosphonates (OB) in a series of women with osteoporosis referred for tooth extraction. Study design: The study included 38 postmenopausal women on treatment with OBs. The following variables were analysed: age, weight, height, type of OB and duration of treatment, bone densitometry and risk factors for osteoporosis. In addition, the osteoporosis self-assessment tool (OST) was administered and collagen type I C-telopeptide (CTX) levels were measured. Results: Bone densitometry had only been performed in six patients (15.7%) before starting OB treatment. Based on the results of the OST, nine (23.6%) of the participants prese…
Jaw osteonecrosis management around a dental implant inserted 2 years before starting treatment with zoledronic acid
2015
Journal Article; Bisphosphonates (BP) are a type of drug known to inhibit bone resorption through complex interventions. Their primary mechanism of action is aimed at the cellular level, inhibiting osteoclast activity and so bone resorption. BPs are widely used, with many patients receiving continuous treatment for years. But it is well known that these drugs can produce osteonecrosis of the jaw (ONJ). Zoledronic acid (ZA) is an intravenous BP used in the treatment and prophylaxis of bone disease in patients with malignant tumors with bone implication. ZA is the most potent BP in clinical development. This report describes the case of a 62-year-old woman with breast cancer antecedents which…
Peri-implantitis-like medication-related osteonecrosis of the jaw: Clinical considerations and histological evaluation with confocal laser scanning m…
2021
Objective: In the recent years, an increasing number of peri-implant medication-related osteonecrosis of the jaw (PI-MRONJ) have been reported in literature, both in oncologic and osteoporotic patients. The aim of this study is to describe 19 cases of patients previously diagnosed as affected by peri-implantitis, who were treated for PI-MRONJ, with consideration on clinical and histopathological features. Materials and Methods: Patients included were affected by postmenopausal osteoporosis and were administered with different antiresorptive drugs. Due to the presence of clinical and radiological signs of peri-implantitis not healed after non-surgical periodontal treatment, they were referre…
