Abstract:
Puberty is the fundamental period for bone mass acquisition. In this period mineralization is found to increase with levels of high bone formation.. The objective of this cross-sectional study was to determine the changes in bone mineral density (BMD) and growth parameters for healthy pubertal males and females at different pubertal stages in Mosul city/Iraq. In addition, we aimed to detect the relationship between BMD, age, pubertal stage and growth parameters, and to reveal the most important determinant of BMD in the pubertal period.

Abstract:
This study assessed change in hematological status among physically active children as they progressed through puberty. Values for serum ferritin, hemoglobin, and hematocrit at all stages of puberty were within the normal range of reference values. Significant changes in serum ferritin were not detected in the different pubertal stages, although serum ferritin was highest in prepubertal boys and girls. There were no significant differences in marginal or deficient iron stores between the sexes at any pubertal stage, suggesting that gender was not predisposing for iron deficiency; however, girl

Abstract:
Puberty is a process that results from a coordinated series of complex neuroendocrine changes which eventually leads to external and internal physical changes. These changes include attainment of primary and secondary sexual characteristics. Puberty as a temporal process is subdivided into different stages. These pubertal stages occur in a sequential manner but significant variations have been seen among different individuals in the timings of pubertal onset as well as a certain degree of gender difference is also present where puberty is occurring earlier in girls than boys.

Abstract:
Abstract Context: Changes in appetite-regulating peptides may impact food intake during puberty and facilitate the pubertal growth spurt. Peptide YY (PYY) is an anorexigenic hormone that is high in anorexia nervosa and low in obesity, inhibits GnRH secretion, and is suppressed by GH administration. The relationship between PYY and GH has not been examined across puberty. Objectives: We hypothesized that PYY would be inversely associated with GH in adolescents and would be lowest when GH is highest.

Abstract The Western tradition of recognizing the change from childhood to puberty is one with deep roots. In the ancient physicians’ and philosophers’ division of life into four stages, adolescence was conceived of as hot and dry, as are summer and fire, and its humor was red choler. Youths, according to Bede, are “lean (even though they eat heartily), swift-footed, bold, irritable, and active.” Those who divided the life cycle into six stages according to the planets envisioned youth as Venus, which “implants an impulse toward the embrace of love.”1 The folkloric traditions, as well, include

Abstract The first stage of clinical management of gender incongruence and dysphoria in childhood (prepubertal years) involves the decision about how to respond to a child’s gender expression.

Enabling a child to express their gender is sometimes referred to as ‘social transition’, which can be partial (at home) or full (outside home). One concern around social transition is that enabling a child to affirm their gender, particularly outside the home environment, might inhibit, rather than facili

Abstract:
Haemophilia B Leyden is characterized by low levels of factor IX antigen and activity before the age of 15, whereas after puberty factor IX levels rise at a rate of about 4-5% per year. To date such a genetic variant of factor IX synthesis has been reported in two (probably related) Dutch families, in a Greek and in an American family of Armenian descent. Laboratory and clinical investigations indicate that the factor IX protein is normal but that the regulation of factor IX synthesis has come under the control of the steroid hormone testosterone. We have started to investigate the factor IX g

Abstract:
Introduction: Germ cell tumours comprise approximately 15-20% of all ovarian tumours. Two third of ovarian tumours in first two decades of life are germ cell tumours. Majority of ovarian germ cell tumours are benign teratomas. The malignant germ cell tumours are usually solid and arise from totipotent germ cells. Over the past 3 decades the clinical outcome of women with ovarian germ cell tumours (OGCT) have significantly improved mainly due to development of more effective chemotherapy regimens. Objective: To study the clinic pathological features, treatment and survival of women with ovarian

Abstract:
The problem under research is of particular importance for the family and society because we can say, without fear of being subjective, that the socialization of children, i.e. their preparation to live in society, is a very topical problem precisely by ignoring its systematic and conscious approach at the level of society , especially in the context where puberty is the period when sports activities are of vital importance for socialization. At this stage of life, the child is sensitive to cognitive and moral development, he assumes different roles, learns that he is different from others and

Abstract:
Kyphosis is an acquired or congenital deformity of the spine. It is the object of study of many scholars and specialists in the field. The recovery of kyphosis depends on the correction of all deviations from the normal, namely the deformation of the physiological curves of the spine, the head and neck tilted forward, the shoulder blades apart and separated from the ribcage, the shoulders brought forward, the chest sunken or in flexion, a deviation of vertebrae. Physiotherapy is constantly coming up with new ideas, programs and protocols, addressed to people diagnosed with functional kyphosis.

Abstract:
Both the genes and cDNA sequences encoding the b-subunits of black carp LH and FSH were isolated, cloned and sequenced. Sequence analysis of the bcFSHb and LHb5'flanking regions revealed that the promoter region of both genes contains canonical TATA sequences, 30 bp and 17 bp upstream of the transcription start site of FSHb and LHb genes, respectively. In addition, they include several sequences of cis-acting motifs, required for inducible and tissue-specific transcriptional regulation: the gonadotropin-specific element (GSE), GnRH responsive element (GRE), half sites of estrogen and androgen

The black carp (bc)GtH IIb cDNA was amplified and isolated, cloned and sequenced. Comparison of the bcGtH IIb deduced a.a. sequence with that of GtH IIb from other teleosts revealed high homology to cyprinid species and a lower homology to salmonid or perciform fish. The gene coding for the GtH IIb was isolated and sequenced. Three bc recombinant phages which hybridized to the goldfish GtH Ib cDNA probe were isolated and are currently being characterized. The region coding for the mature GtH IIb was expressed in a bacterial expression vector resulting in the production of a recombinant protein

Abstract:
We focus on gender and sexual diversity in the secondary school setting due to the important role that education systems play in reducing social distance between individuals. Adolescence is also a crucial stage in which individuals construct their identities, develop their personalities, and have a tendency to experiment. Moreover, adolescence is a stage in which the levels of bullying and cyberbullying dramatically increase relative to infancy or puberty. LGBT students are particularly prone to being victimized in schools, yet there has been little work analyzing whether a larger presence of

Abstract:
Many factors affect growth rate in fish: environmental, nutritional, genetics and endogenous (physiological) factors. Endogenous control of growth is very complex and many hormone systems are involved. Nevertheless, it is well accepted that growth hormone (GH) plays a major role in stimulating somatic growth. Although it is now clear that most, if not all, components of the GH-IGF axis exist in fish, we are still far from understanding how fish grow. In our project we used as the experimental system a marine fish, the gilthead sea bream (Sparus aurata), which inhabits lagoons along the Mediter

Abstract:
Oxytocin has multiple actions in bovine reproductive tract and it was our purpose to determine the nature of these actions and their significance for the physiology of bovine reproduction. The bovine oxytocin receptors (OTR) gene was cloned and its expression studied during the cycle and pregnancy. OTR mRNA changed in parallel with OTR with control occurring mainly at the transcriptional level. However, the endocrine regulation of OTR were found in endometrium and cervical mucosa at estrus and at parturition. In both tissues OTR were suppressed in the luteal phase and early pregnancy.
