The present study was undertaken to determine the effects of malathion exposure on oxidative stress, functional and metabolic parameters in kidney and liver of prepubertal male mice. For this reason, two separated groups of prepubertal male mice were used in this experiment. Animals were divided into two groups, group 1 served as a control and received the corn oil and group 2 was treated with 200 mg/kg body weight (b.w.) of malathion for 30 days. In result, we found that the malathion administration led to the perturbation of biochemical markers and histopathological as well as molecular damages. These changes were accompanied by an oxidative alternation which was evaluated by lipoperoxidation process and MDA production, a diminution of sulfhydril groups (-SH) content and an antioxidant enzyme activities depletion such as total superoxide dismutase (SOD) and its isoforms, catalase (CAT) and glutathione peroxidase (GPx) in both kidney and liver tissues. These changes were related with many histopathological lesions in the liver and kidney tissues. More importantly, this insecticide clearly caused a decline in the GPx-4 expression in liver as well as GPx-3 in kidney. These data suggest that prepubertal male mice exposure to malathion showed a marked deregulation of liver and kidney functions.

Anxiety is among the most prevalent mental health issues in children. While it is well established that gonadal steroids influence anxiety-like behavior in adulthood, a potential role in prepubertal juveniles has been overlooked because it is commonly thought that the gonads are quiescent during the juvenile period. However, the juvenile gonads secrete measurable amounts of steroids, and we have recently found that prepubertal ovariectomy decreases anxiety-like behavior of juvenile Siberian hamsters in the light/dark box test.

Introduction: The early diagnosis of mandibular asymmetry (MA) in patients with unilateral cleft lip and palate (UCLP) can contribute to its treatment.
Objective: The aim of this study was to evaluate the occurrence and the extent of MA in UCLP patients at different growth stages.
Methods: Cone-beam computed tomography (CBCT) of 47 UCLP patients were included, and divided into two groups (prepubertal stage and pubertal stage).

Male infertility is among one of the most challenging health concerns in the world. Traditional therapeutic interventions such as semen and testicular tissue cryopreservation aim to restore or preserve male fertility. However, these methods are subject to limitations that impact their efficacy and are infeasible in cases such as patients who cannot produce mature sperm due to genetic or pathological disorders.

Objective: Adreno CorticoTropic Hormone (ACTH)-independent Cushing's syndrome (CS) in children is very rare but potentially fatal. In bilateral nodular hyperplasia, synchronous bilateral adrenalectomy (SBA) represents the definitive treatment to correct hypercortisolism. We aim to report the multidisciplinary management of this rare condition.

There is an ongoing debate regarding the necessity for sex-segregated sports particularly in youth. However, there has been minimal evaluation of prepubertal sex-based differences in the events of shot put, javelin throw, and long jump. Therefore, the top eight performances from the USA Track and Field National Youth Outdoor Championships and National Junior Olympic Championships during the years 2016-2023 for shot put, javelin throw, and long jump in the 8-and-under and 9-10-year-old age groups were analyzed for sex-based differences.
