This study investigated the relationship between chronological age and pulp tooth area ratio (PTR) in maxillary central teeth using cone-beam computed tomography (CBCT) images in the Turkish population. The sample consisted of CBCT images of 120 male and female subjects between 14 and 75 years old. The PTR of the maxillary central teeth was calculated using inVivo 5 software (Anatomage, San Jose, CA). Data were analyzed with independent t-test and Pearson's rank correlation test. There was a significant negative correlation between chronological age and PTR (r = -0.615). The results showed that the PTR of maxillary central teeth is a reliable method for age estimation in the Turkish population.

Inflammation mediates the association between muscle mass and accelerated phenotypic aging: results from the NHANES 2011-2018.
Front Nutr
January 2025
Department of Orthopedics, Chengdu Fifth People's Hospital, Chengdu, China.
Background: Muscle mass plays a pivotal role in health maintenance, yet its connection to biological aging remains underexplored. This study investigates the association between appendicular skeletal muscle mass index (ASMI) and phenotypic age(PhenoAge), while examining the mediating role of systemic inflammation.
Methods: The analysis included 7,440 participants from the NHANES 2011-2018.
Delayed macular development in preterm infants with spontaneously regressed retinopathy of prematurity.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Children's Hospital of Fudan University, National Children's Medical Center, Wanyuan Road No.399, Shanghai, 201102, China.
Purpose: To evaluate the macular development in preterm infants with spontaneously regressed retinopathy of prematurity (ROP) utilizing handheld spectral domain optical coherence tomography (SD-OCT) during the early postnatal period.
Design: A cross-sectional observational study.
Methods: Using handheld SD-OCT, OCT images were acquired in non-sedated infants ages about 37 weeks(w) post-menstrual-age (PMA = gestational age in weeks + chronological age).
Background: To measure the aging process before a cancer diagnosis, we developed the first cancer-specific proteomic aging clock (CaPAC) and examined its association with cancer risk in the Atherosclerosis Risk in Communities (ARIC) and Multi-Ethnic Study of Atherosclerosis (MESA) studies.
Methods: Using the SomaScan assay, ARIC measured 4,712 proteins in plasma samples collected in 1990-92 from 3,347 participants who developed cancer over follow-up until 2015 and 7,487 who remained cancer-free, all aged 46-70. We constructed CaPAC0 using elastic net regression among two-thirds randomly selected cancer-free participants (N=4,991, training set) and calculated age acceleration for CaPAC0 (CaPAA0) as residuals of CaPAC0 on chronological age in all remaining ARIC participants.
Background: Physiological age (PA) derived from clinical indicators including blood-based biomarkers and tests of physiological function can be compared with chronological age to examine disparities in health between older adults of the same age. Though education interacts with sex to lead to inequalities in healthy ageing, their combined influence on longitudinally-measured PA has not been explored. We derived PA based on longitudinally-measured clinical indicators and examined how sex and education interact to inform PA trajectories.
