Objective: Recently, a lot of research has been done around the world to popularize the osseointegration of dental implants. In this study, it was investigated the effect of local zoledronic acid application on implants with machined (MAC), resorbable blast materials (RBM), sandblasted and acid-etched (SLA) surface implants integrated in rat tibias.
Methodology: A total of 60 female Wistar rats weighing between 270 and 300 g were used in the study. The rats were passing divided into six classes: controls; MAC (n = 10), RBM (n = 10), SLA (n = 10), and local zoledronic acid (LZA) applied groups; LZA-MAC (n = 10), LZA-RBM (n=10) and LZA-SLA (n = 10) and implants were surgically placement into rat tibias in general anesthesia. After a four-week experimental period, the biomechanical bone implant connection level was determined with reverse torque analysis.
Results: Osseointegration levels were detected highly in SLA and RBM surface compared with the machined surfaced implants in both control and treatment groups (p < 0.05). Additionally, local application of zoledronic acid in both three groups; implants increased the biomechanic osseointegration level compared with the controls (p < 0.05).
Conclusion: In this research, we observe that the local application of the zoledronic acid could increase the osseointegration, and RBM and SLA surface could be better than machined surfaced implants in terms of bone implant connection. In addition, local application of zoledronic acid may be a safer method than systemic application.

Background: The Hormonal Bone Effects (HOBOE) study tested whether adjuvant triptorelin plus either letrozole (L) or zoledronic acid (Z) plus L (ZL) was more effective than tamoxifen (T) in premenopausal patients with hormone receptor-positive (HR+) early breast cancer (BC). Here we report the long-term follow-up analysis.

Cervical cancer (CC) is a malignant tumor in females characterized by high incidence and mortality rates, often resulting in a poor prognosis for patients. Zoledronic acid (ZA), a third-generation bisphosphonate, exhibits anti-tumor properties across various types of tumors. To further understand the effect of ZA in the treatment of CC, this article included two kinds of human CC cells (CCCs) as the research object, examining the impact of varying levels of ZA on the cells' biological properties.

Zoledronic acid (ZA), a bisphosphonate, is commonly used in breast cancer patients with bone metastases to treat hypercalcemia and osteolysis. Recent studies showed the anti-cancer effects of ZA in breast cancer. This study further explored the synergistic effects of sequential and nonsequential ZA and doxorubicin (DOX) administration on estrogen receptor (ER)-positive and -negative breast cancer cell lines.

Hajdu-Cheney syndrome (HCS), caused by a heterozygous gain of function variant of the NOTCH2 gene, is a rare skeletal dysplasia. Although the main presentation is acro-osteolysis, osteoporosis, and facial dysmorphism, having a wide range of clinical manifestations creates diagnostic difficulties. Here, a 15-year-old male patient with HCS who had no complaints until this age except for two short bone fractures and one vertebral collapse fracture due to a fall was reported.
