Qualitative and quantitative assessment of infraoccluded deciduous teeth: a systematic review.
Head Face Med

Department of Orthodontics, Clinic of Dentistry, Philipps University Marburg, Georg-Voigt-Str. 3, 35039, Marburg, Germany.
Background: Infraocclusion of deciduous teeth is a frequent dental anomaly caused by ankylosis accompanied by local growth disturbance. During puberal growth spurt an increasing progression of infraocclusion is detected. The clinical classification of ankylosed deciduous teeth varies considerably among scientific studies.

The influence of biological maturity status on talent identification and development in youth soccer has been debated extensively. Alternative methods have thus recently emerged to estimate maturity status, such as the Pubertal Development Scale (PDS), but their relationship with physical capabilities of young soccer players still needs to be determined. The present study investigated the relationships of different PDS-derived pubertal status measures, chronological age, and relative age with selected performance variables in youth soccer.

Background: Epidemiologic studies suggested the association between prenatal di-(2-ethylhexyl) phthalate (DEHP) exposure and disorders of sex development (DSD), adult male disorders, and reproductive aging. Inhibiting testosterone synthesis by interfering with steroidogenic gene expression induces testicular toxicity, however, whether prenatal DEHP exposure induces testicular toxicity through this mechanism remains uncertain.
Methods: C57BL/6JGpt male mice underwent different doses (0, 100, 500, 1,000 mg/kg) of prenatal DEHP exposure during gestational day 10 to delivery day, the testicular toxicity (genital development, testosterone, semen quality, and morphology of testis tissue) in the neonatal, post-puberal and middle-aged stages was observed, and the steroidogenic gene (, , , , , and ) expression was analyzed by quantitative polymerase chain reaction (qPCR) and Western blot (WB).
The impact of suppressing puberty on neuropsychological function: A review.
Acta Paediatr
June 2024
UCL, Queen Square, Institute of Neurology, London, UK.
Aim: Concerns have been raised regarding the impact of medications that interrupt puberty, given the magnitude and complexity of changes that occur in brain function and structure during this sensitive window of neurodevelopment. This review examines the literature on the impact of pubertal suppression on cognitive and behavioural function in animals and humans.
Methods: All studies reporting cognitive impacts of treatment with GnRH agonists/antagonists for pubertal suppression in animals or humans were sought via a systematic search strategy across the PubMed, Embase, Web of Science and PsycINFO databases.
Effects of caffeine supplementation on anaerobic power and muscle activity in youth athletes.

Article Synopsis
- - This study examined how caffeine affects anaerobic performance and muscle activity in young male futsal players through a randomized trial involving caffeine and placebo ingestion before a Wingate test.
- - Results indicated that caffeine significantly boosted both peak and mean power output, but did not change the fatigue index or electromyographic (EMG) parameters significantly.
- - Overall, the findings suggest that caffeine can enhance anaerobic performance in young athletes without impacting muscle activity readings.
