Background: Puberty is a transition period between childhood and adulthood influenced by various complex factors. Nutrition is one of the most important factors affecting pubertal development. Overweight or obese children are more likely to enter puberty earlier. Severe primary or secondary malnutrition can also delay the onset and progression of puberty. This study aims to determine the relationship between nutritional status and pubertal disorders in Denpasar city orphanage children. Methods: This study was conducted using an analytic research design with a cross-sectional design to determin

The human is the product of the specific interaction of natural and social factors. Periods of age were divided by specialists differently; Demeter, A. [80] divides from a functional point of view the school-age of 6-18 years old into three periods, unequal in duration, namely: - the small one (ante pubertal) school period 6-11 years-old; - middle school period (puberty) 11-13 years-old in girls, 12-14 years-old in boys; -high school period (post-puberty) 14-18 years-old.

The androgynous syndrome was combined with menstrual dysfunction in 56 patients and coursed as idiopathic hirsutism (with regular biphasic cycle) in 9.

Adolescent is one of the stages in human life that is very critical, because it is a stage of transition from childhood to adulthood. At this stage a lot of changes occur in adolescents, such as physical, emotional and social changes. This period of change is commonly referred to as the period of puberty. The puberty period is also considered an overlapping period because it covers the final years of the childhood period and the early years of the teenage period. Changes experienced by adolescents in the puberty period are often troubling because the various changes that occur are considered a

The fertility of ewe lambs is usually lower than that of mature ewes. Early embryo loss has been implicated as a cause of reduced fertility, especially when matings occur at the pubertal oestrus (Hare and Bryant, 1985). The Introduction of vasectomised rams to ewe lambs may hasten the occurrence of puberty and, if the introduction of fertile rams is not advanced, mating may occur later in the breeding season with possible advantages to fertility. This experiment investigated the effects of a period of association with vasectomised rams preceding the introduction of entire rams upon (1) the occ

Developmental changes within the hypothalamus are necessary for maturation of the reproductive neuroendocrine axis. Recent reports have implicated several neuronal networks in this process, but genes involved in their regulation have not been elucidated.

Presented thesis deals with the eighth-grade elementary school pupils' view on social factors significantly affecting their learning motivation. The paper is of theoreticaly-empirical character. The base for the theoretical part is consisted of definitions of the main concepts, such as motivation and learning, social factors, environment, adolescence and demarcation of the major social factors influencing learning motivation. The main goal of the empirical part is to find out, to what extent social factors (parents, teachers, peers) are influential to learning motivation of the eight-graders.

Abstract Early adolescence (ages 10-14) is a period of important developmental transitions. Changes occur in cognitive, emotional, and social functioning and, most strikingly, with the onset of puberty, in physical stature and body contour. In recognition of accumulating evidence of the interrelatedness of psychological functioning and pubertal changes during early adolescence, researchers studying this period of development increasingly are examining psychological processes in relation to the processes of pubertal development.

Abstract There has been considerable debate over the years regarding how to define puberty, in that it is a stage of development that spans an ex tended period of time (in humans and higher primates a period of years) and encompasses a large variety of morphological, physiological, and behavioral changes. However, this chapter will specifically focus on the maturational changes in the reproductive system that occur during puberty. In this context, puberty can be defined as the period of transition from a state of reproductive immaturity to a state of full reproductive competence.

However, an arrest of maturation occurs shortly thereafter, and the hypothalamic-pituitary-gonadal axis appears to be nearly dormant during early childhood (Conte et al., 1980).

Childhood growth is slower but with mini-growth spurts. Pubertal physical changes are linked to the rapid acceleration and deceleration of adolescent growth. Puberty is assessed by Tanner staging, but a simpler non-invasive system of the assessing the puberty phases (prepuberty, in puberty, and completing puberty) may be more helpful in daily practice.

In 2019, approximately 29,000 children (up to 15 years of age) were involved in road traffic accidents in Germany. The cohorts with the most accident victims are the 11- to 14-year-olds, about half of whom (approx. 6,000 children) were involved in accidents by bicycle. The number of cyclists involved in accidents rises sharply after the transition from primary to secondary school. This is due to a change in driving behavior after the change of school compared to the primary school period. Many pupils start cycling to school after changing to secondary school. Furthermore, extensive behavioral

The work analyzes the effect of proton radiation at a dose of 10 Gy on the survival and fertility of crustaceans Daphnia magna. Daphnia were exposed to radiation during the juvenile and pubertal periods of ontogenesis. It has been shown that proton radiation does not affect the survival of crustaceans. The effect of proton radiation is manifested in a change in a more sensitive indicator - fertility. A significant decrease in the fertility of D. magna may be associated with the cytotoxic effect of radiation on germ cells and may affect subsequent generations, which requires additional research

The human body needs a variety of nutrients, for a normal fucntionality, and a major one of them is the fat-soluble Vitamin D. This vitamin can be found in several forms, but the most important for human body is Vitamin D2 and D3. The D2 form, named ergocalciferol, is produced by plants and mushrooms. It is also spread in different types of grains - rye, oat, wheat, barley. The Vitamin D3 ("The vitamin of the sun"), also named - cholecalciferol, of animal origin, is synthesized by the organism in 80-90% proportions. It is due to the contact of the B ultraviolet rays and the specific receptors

The normal growth and development of the human body is a critical and highly sensitive process. Despite humans continuously developing throughout life, there are certain periods of development which are more sensitive to adverse factors. These are known as critical windows of susceptibility and include development in utero (in the womb), the postnatal period, puberty, pregnancy and menopause. During these periods the mammary gland (breast) undergoes extensive development. Research suggests that exposure to harmful chemicals such as Endocrine Disrupting Chemicals (EDCs) during these critical pe

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.
