BACKGROUND/PURPOSE The age at menarche reflects a pubertal girl's physiologic maturity. The aims of this study were to evaluate the relationship between the age at menarche and skeletal maturation in female orthodontic patients. METHODS Hand-wrist radiographs and lateral cephalometric radiographs from 304 adolescent female subjects (age, 8-18.9 years) were selected from the files of the Depar...

BACKGROUND Arteriovenous fistula maturation requires dilatation of the anastomosed artery and vein. The factors that affect dilatation and the mechanisms by which dilatation promotes maturation are not understood. This pilot study tested two hypotheses: that low arterial elasticity is associated with maturation failure, and that vessel dilatation is required for adequate fistula blood flow duri...

BACKGROUND Studies of the effect of childhood obesity on bone accrual during growth have yielded conflicting results, largely related to the failure to adequately characterize the confounding effects of growth, maturation, and body composition. OBJECTIVE The objective of this study was to determine the effect of childhood obesity on skeletal mass and dimensions relative to height, body compos...

BACKGROUND The aim of this study was to assess the results of using the Ilizarov apparatus to transport bones in the treatment of benign bone tumors. METHODS Seven patients (six males and one female) with benign bone tumors were treated by bone transport with an Ilizarov apparatus at our institution. Their mean age at surgery was 14.4 years (range, 4.8 to 36.9 years). The histological diagnos...

The objective of this study was to analyze the genetic diversity among colored cotton fiber genotypes using technological characteristics fiber, seed yield and percentage identify potential parents with high performance. experiment conducted in Brazilian city Uberlândia, Minas Gerais, during 2016/2017 harvest. Twelve were used a randomized block design. that evaluated included micronaire, matur...

in teleosts the insulin-like growth factor-i, a member of igf system, play an important role in the control of growth and reproduction including metabolism, cell division, oogenesis, final oocyte maturation and secretory activity. this system is controlled by several hormones and metabolic status. serum igf-i, thyroxine (t4) and cortisol levels were studied in two female brood stocks (caught fr...

AIM The aims of this study were to compare ultrasound fetoplacental parameters and to calculate Hepato-Cephalic Index (HCI) as a new predictor of IUGR. METHODS AND MATERIAL A clinical prospective study was conducted and included 120 pregnant women divided in two groups: non IUGR group included healthy pregnant women (n=60) and IUGR group included pregnant women with preeclampsia and IUGR (n=6...

  Background & Aim: Considering that antioxidants are known as effective free radicals scavenger, it may be able to improve the in vitro oocyte maturation and the fetal quality. This study was designed to determine the effect of Gundelia tournefortii leaves (GTE) hydro-alcoholic extract as a source of antioxidant on in vitro oocyte maturation. Experimental: Germinal vasicle (GV) were...

The aim of the study was to find a correlation between the evaluation of skeletal maturation performed by the study of cervical vertebrae maturation indicators and the evaluation obtained by the hand and wrist maturation indicators. A radiographic hand-wrist bone analysis and cephalometric cervical vertebral analysis of 100 patients (36 males and 64 females) ranging from 9 to15 years were exami...
