The relative impact of parenting on socio-emotional development of children has rarely been examined in a longitudinal context. This study examined the association between perceived parenting styles and socio-emotional functioning from childhood to adolescence. We hypothesized that optimal parenting associated with improvement in socio-emotional functioning from childhood into early adulthood, especially for those with more behavioral problems in childhood. Children between ages 7 and 9 years were recruited for the Singapore Cohort Study of Risk Factors for Myopia (SCORM)...

BACKGROUND: Many surveys have shown that older children are ubiquitously exposed to bisphenol A (BPA), and many laboratory studies have shown that BPA exposure has adverse effects related to estrogenic disruption, whereas the evidence in infants has not yet been observed. METHODS: Women in early pregnancy were recruited by the Maternal and Child Health and Family Planning Service Center, Daishan, China, from March 2012 to December 2014. After delivery, urine samples were collected from the diapers of 59 infants (0 to 6months of age)...

MiRNAs (microRNA) constitute a large family of single-stranded, non-coding small RNAs. Although the functions and target genes of most miRNAs are still unknown, it has been well established that they are involved in embryogenesis, organogenesis and neonatal birth. In recent decades, interest in buffalo breeding has largely increased worldwide thus focusing the attention on this species as a dairy purpose animal. Problems related to long calving interval, late puberty and seasonal anestrus hamper reproductive efficiency in this species...

BACKGROUND: To evaluate the long-term impact of preterm birth on respiratory function in female patients born preterm, we undertook spirometric examinations twice, as they reached the age of puberty, then follow-up examinations of part of the same cohort in adulthood. We sought evidence that preterm birth is correlated with poorer spirometric results into adulthood. METHODS: A total of 70 girls (aged 12.2 ± 1.5 years in 1997) who had been born preterm (at 34.7 ± 1...

Anti-Mullerian hormone (AMH), secreted by immature testicular Sertoli-cells, triggers the regression of male fetal Mullerian ducts. During puberty, AMH is downregulated by intratesticular testosterone. In females, AMH is secreted from granulosa cells of immature ovarian follicles from late prenatal life until menopause; serum concentration is 5-20 times lower in females than in males through lifetime. In boys, AMH determination is useful in the clinical setting as a marker of Sertoli cell function. Serum AMH is low in infants with hypogonadotrophic hypogonadism (and increases with FSH treatment), in patients with primary hypogonadism from early postnatal life and in Klinefelter syndrome from midpuberty...

BACKGROUND: Van Wyk-Grumbach syndrome (VWGS) is a rare presentation of juvenile hypothyroidism which manifests in females as chronic autoimmune hypothyroidism, isosexual pseudoprecocious puberty, and multicystic ovaries. It uniquely presents with short stature and delayed bone age unlike other causes of precocious puberty. Kocher-Debré-Sémélaigne (KDSS) is a rare presentation of juvenile hypothyroidism manifesting as calf muscle pseudohypertrophy, delayed contraction and relaxation of reflexes, and percussion myxedema...

PURPOSE: The goal of the current work is to challenge the enduring notion that pre-puberty is the optimum timing for maximum bone response to exercise in childhood, and to present the evidence that early puberty is a more a potently receptive period. METHOD: The relevant literature is reviewed and the causes of the misconception addressed in detail. RESULTS: Contrary to prevailing opinion, ample evidence exists to suggest the peri-pubertal years represent the developmental period during which bone is likely to respond most robustly to exercise intervention...

REVIEW
Genevieve Victoria Dall, Kara Louise Britt
A woman has an increased risk of breast cancer if her lifelong estrogen exposure is increased due to an early menarche, a late menopause, and/or an absence of childbearing. For decades, it was presumed that the number of years of exposure drove the increased risk, however, recent epidemiological data have shown that early life exposure (young menarche) has a more significant effect on cancer risk than late menopause. Thus, rather than the overall exposure it seems that the timing of hormone exposure plays a major role in defining breast cancer risk...

INTRODUCTION: In 2014, 60 million youth ages 6-18 participated in some form of generalized athletics. 3.5 million children are injured annually participating in organized sport or recreational activities. While sound physical education can decrease the burden of youth sports injuries, the median annual physical education budget of $764 for United States elementary, middle and high schools may not allow enough flexibility to apply evidenced-based guidelines. EVIDENCE ACQUISITION: The topics were selected after a careful review of the 2016 National Strength and Conditioning Association Position Statement on Long-Term Athletic Development...

BACKGROUND: Augmentation index (AIx) is a noninvasive measure of pulse wave reflection. AIx is associated with cardiovascular disease. Adult women have a higher AIx than men, but the factors determining this sex-related difference remain to be determined. METHODS: To examine factors associated with AIx in adolescents, participants in the Childhood Asthma Prevention Study, followed from birth, were assessed at age 14 years, with AIx standardized to a heart rate of 75/min (AIx_75) and pulse wave velocity...

The RhoA subfamily of Rho GTPases regulates actin-based cellular functions in bone such as differentiation, migration, and mechanotransduction. Polymorphisms or genetic ablation of RHOA and some of its regulatory guanine exchange factors (GEFs) have been linked to poor bone health in humans and mice, but the effects of RhoA-specific GTPase-activating proteins (GAPs) on bone quality have not yet been identified. Therefore, we examined the consequences of RhoGAP Myo9b gene knockout on bone growth, phenotype and cellular activity...

BACKGROUND: Spermatogenesis is a complex process characterized by the activation and/or repression of a number of genes in a spatio-temporal manner. Pubertal development in males starts with the onset of the first spermatogenesis and implies the division of primary spermatogonia and their subsequent entry into meiosis. This study is aimed at the characterization of genes involved in the onset of puberty in European sea bass, and constitutes the first transcriptomic approach focused on meiosis in this species...

Early experiences are critically important for female reproductive development. Although a number of early childhood hardships predict earlier physical development in girls, research on specific populations suggests a distinct effect of childhood sexual abuse compared to other adversities. This study leverages the National Longitudinal Study of Adolescent Health (N = 6,273 girls) to test the generalizability of these findings, examining associations of early physical abuse, sexual abuse, and physical neglect with pubertal timing...

While native blood group A-like glycans have not been demonstrated in prokaryotic microorganisms as a source of human "natural" anti-A isoagglutinin production, and metazoan eukaryotic N-acetylgalactosamine O-glycosylation of serine or threonine residues (O-GalNAc-Ser/Thr-R) does not occur in bacteria, the O-GalNAc glycan-bearing ovarian glycolipids, discovered in C57BL/10 mice, are complementary to the syngeneic anti-A-reactive immunoglobulin M (IgM), which is not present in animals that have undergone ovariectomy prior to the onset of puberty...

Puberty is a stage of sexual development determined by the interaction of environmental factors and genetic mechanisms. Among them, thyroid function plays a key role in sexual development and spermatogenic function and is under the control of several genes, including the well-described thyroglobulin gene (TG). Previous reports have shown genetic association between thyroid function and selected single nucleotide polymorphisms (SNPs) in taurine cattle. Therefore, the identification of genetic mechanisms involved in the regulation of this trait can assist with the selection for early pubertal bulls, thus improving genetic progress in livestock breeding...

The frontal cortex matures late in development, showing dramatic changes after puberty onset, yet few experiments have directly tested the role of pubertal hormones in cortical maturation. One mechanism thought to play a primary role in regulating the maturation of the neocortex is an increase in inhibitory neurotransmission, which alters the balance of excitation and inhibition. We hypothesized that pubertal hormones could regulate maturation of the frontal cortex by this mechanism. Here, we report that manipulations of gonadal hormones do significantly alter the maturation of inhibitory neurotransmission in the cingulate region of the mouse medial frontal cortex, an associative region that matures during the pubertal transition and is implicated in decision making, learning, and psychopathology...
