For fish stocks managed using biological reference points based upon spawning biomass, it is critical to have accurate maturity schedules. We investigated sizeand age-dependent patterns in maturity for southern flounder Paralichthys lethostigma, a flatfish supporting valuable coastal fisheries in North Carolina and throughout its range. We evaluated both macroscopic and histological methods ove...

Age-related declines in physiological performance have been documented in a wide variety of organisms. However, it is unknown whether related species age in a similar manner or whether physiological differences associated with aging differ widely among species. Previous work has shown that the desiccation resistance of Drosophila melanogaster decreases rapidly with age. Other Drosophila species...

BACKGROUND Age assessment may be a crucial step in postmortem profiling leading to confirmative identification. In children, Demirjian's method based on eight developmental stages was developed to determine maturity scores as a function of age and polynomial functions to determine age as a function of score. AIM Of this study was to evaluate the reliability of age estimation using Demirjian's...

background: one of the factors that can improve self-concept and performance of staff is professional maturity. professional maturity can also solve the problems of self-concept. the purpose of this paper was to identify the relationship between the dimensions of self-concept and professional maturity.   materials and methods: this relative applicable study was performed on all the personnel (n...

AIM The aim of this study was to establish the validity of a new method for evaluating skeletal maturation by assessing the 3rd and 4th cervical vertebrae seen in the cephalometric radiograph. MATERIALS AND METHODS This study consisted of a sample of 50 patients in the age group of 8 to 14 years of age. Chronologically, they were divided into six groups, based on the age consisting of a minim...

BACKGROUND Physical activity (PA) is beneficial, enhancing healthy development. However, one-third of school-age children practicing sports regularly suffer from an injury. These injuries are associated with sex, chronological age, and PA level. PURPOSE To identify the importance of age, PA level, and maturity as predictors of injury in Portuguese youth. STUDY DESIGN Descriptive epidemiolog...

The aim of this investigation was to study dental maturity in healthy prepubertal children of short stature (height<-2 SD), with or without growth hormone (GH) deficiency, compared to healthy controls. The GH-deficient group (GH level<10.0 microg/l) included 29 children (11 female, 18 male) with a mean age of 10.2+/-2.2 years. The GH non-deficient group consisted of 17 children (5 female, 12 ma...

PURPOSE Percutaneous epiphysiodesis using transphyseal screws (PETS) was developed as a minimally invasive outpatient procedure to address limb-length discrepancy (LLD) that allowed immediate postoperative weight bearing and was potentially reversible by removing the screws. The aims of our study were to report our results using PETS for LLD and evaluate the accuracy of three growth predictor m...
