Examination of the effect of treatment of severe early childhood caries and fluoride varnish applications on salivary oxidative stress biomarkers and antioxidants.

Background: Saliva contains a variety of biochemical compounds, including antioxidants, and serves as the body's first line of defense against oxidative stress caused by free radicals. The aim of this study was to investigate the effects of dental treatments on salivary oxidative stress biomarkers in children aged 3-5 years with severe early childhood caries (S-ECC) compared to children without caries.

Method: This study was conducted on 20 children aged 3-5 years with severe early childhood caries (S-ECC) and 20 children without caries.

Predicting the risk of cesarean hysterectomy in the management of placenta accreta spectrum disorders: a new model based on clinical findings and ultrasonography.

Purpose: To develop a nomogram to predict the probability of cesarean hysterectomy (CH) in placenta accreta spectrum disorders (PASD) patients.

Methods: Data from 520 patients who underwent surgery with a preliminary diagnosis of PASD at a tertiary center in southeast Turkey between 2013 and 2023 were collected, and 302 patients were included in the study. A predictive model based on clinical and ultrasonographic variables was developed using penalized maximum likelihood estimation (PMLE) regression analysis.

Photosynthesis and hydrogen energy for sustainability: harnessing the sun for a greener future.

At the dawn of the 21 century, the rapid expansion of manufacturing plants and the widespread destruction of natural habitats significantly contributed to accelerating global warming. This phenomenon has led to severe droughts, irreversible agricultural damage, and substantial challenges in securing food supplies for the burgeoning global population. The alarming surge in atmospheric carbon dioxide concentrations underscores the urgent need to embrace clean energy technologies.
