AI Article Synopsis
- A study investigated how alendronate affects the prevention and treatment of aseptic loosening of prosthetic devices using a rat model.
- Thirty-nine rats were divided into three groups: a negative control, a positive control, and an experimental group that received alendronate treatment.
- Results showed that alendronate effectively prevented bone loss caused by wear particles and reduced levels of inflammatory markers, suggesting its potential use in managing loosening of prostheses.
Article Abstract
Objective: To investigate the effect of alendronate on the prevention and treatment of aseptic loosening of prosthesis.
Methods: A rat model of particle-induced osteolysis was used. Thirty-xis SD rats were divided into three groups: negative control group, positive control group and experiment group. Alendronate was administered by ig in experiment group. Positive control group and experiment group received intro-articular injections of ultrahigh molecular weight polyethylene (UHMWPE) particles at 4, 6, 8, 10 weeks postoperatively. Negative control group was received injection with mixture solution of mouse serum and PBS only. All animals were sacrificed at 12 weeks after operation for histologic examination. In vitro human peripheral blood mononuclear (PBMC)were separated and cultured and divided into five groups as group A: PBMC group, group B: PBMC and particles,group C:PBMC and particles with 10(-4) mol/L alendronate, group D:PBMC and particles with 10(-5) mol/L alendronate, group E: PBMC and particles with 10(-6) mol/L alendronate. The production of IL-1beta, IL-6, TNF-alpha in each group were tested.
Results: Alendronate could prevent particle-induced osteolysis. The production of IL-1beta, IL-6, TNF-alpha was inhibited when alendronate was used.
Conclusion: Alendronate can inhibit bone absorptive factors expression induced by wear particles and may be used in the prevention and treatment of aseptic loosening of prosthesis.

Background: Young gay, bisexual, and other men who have sex with men have been referred to as a "hard-to-reach" or "hidden" community in terms of recruiting for research studies. With widespread internet use among this group and young adults in general, web-based avenues represent an important approach for reaching and recruiting members of this community. However, little is known about how participants recruited from various web-based sources may differ from one another.

Background: Excessive fluoride exposure leads to increased oxidative stress and lipid peroxidation, causing harmful effects on the metabolic organs in the human body. Betanin, a pigment obtained from beetroot, is seen to have powerful anti-inflammatory and antioxidant. The study was conducted to determine the role of betanin in fluoride induced hepato-renal toxicity in Wistar rats.

In Spain, the agricultural sector relies heavily on migrant workers, especially during seasonal seasons. However, these workers face significant challenges related to precarious working conditions and structural vulnerability, which have become more acute since the outbreak of the COVID-19 pandemic. This descriptive qualitative study was based on 87 personal interviews with health and social professionals from sectors such as NGOs, social services, trade unions, local institutions, and health services to promote compliance with these measures in four Spanish regions.
