Puberty News and Research

RSS

Puberty is the maturation stage a person goes through when they develop secondary sexual characteristics. Usually, puberty occurs between the ages of 8 and 12 years in girls and between 9 and 14 years in boys.

New findings provide better picture of pubertal growth

In monitoring and prediction of children's growth, the spurt in puberty is often considered too variable to be predictable. However, new findings and methods enable a better picture of how children and adolescents grow, especially during puberty.

Early detection of pediatric epilepsy possible through 'deep learning' technique

Early detection of the most common form of epilepsy in children is possible through "deep learning," a new machine learning tool that teaches computers to learn by example, according to a new study that includes researchers from Georgia State University.

NIH funding will allow four pediatric health systems to study causes of growth disorders

The National Institutes of Health awards Andrew Dauber, M.D., MMSc, the chief of endocrinology at Children's National Health System, a five-year grant that will allow four pediatric health systems to compile and study clinical and genetic markers of severe pediatric growth disorders.

Research uncovers how sleeping stem cells in the mammary gland are awakened at puberty

Walter and Eliza Hall Institute researchers have discovered how the growth of milk-producing mammary glands is triggered during puberty. Sleeping stem cells in the mammary gland are awoken by a protein dubbed FoxP1, according to the research that was published today in the journal Developmental Cell.

Resemblance to parents increases with offspring age in monkeys

Most of us would acknowledge that family members often resemble one another, particularly in the face. Indeed, humans are good at picking out pairs of close relatives amongst the faces of unfamiliar adults.

Study identifies molecular switch that controls fate of milk-producing breast cells

A research team, led by investigators from Georgetown Lombardi Comprehensive Cancer Center, details how a natural and dramatic process -- changes in mammary glands to accommodate breastfeeding -- uses a molecular process believed to contribute to survival of pre-malignant breast cells.

Study links scoliosis to essential dietary mineral

Nobody knows why some children's backs start to curve to one side just as they hit puberty. Most children diagnosed with scoliosis, or curvature of the spine, have no known risk factors.

Research reveals how critical oocyte quality control process works

Females are born with a finite number of eggs that are steadily depleted throughout their lifetime. This reserve of eggs is selected from a much larger pool of millions of precursor cells, or oocytes, that form during fetal life.

Vitamin D may reduce breast cancer mortality in women with lower BMI

Vitamin D is already well known for its benefits in building healthy bones. A new study supports the idea that it also may reduce cancer risk as well as breast cancer mortality, especially in women with a lower body mass index.

Research shows enlarged genotype-phenotype correlation for three-base pair deletion in NF1

International collaborative research led by Ludwine Messiaen, Ph.D., shows that while a three-base pair, in-frame deletion called p.Met992del in the NF1 gene has a mild phenotype for people with the genetic disorder neurofibromatosis type 1, or NF1, the mutation does cause complications.
