TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Tanner stages of thelarche in relation to anthropometric and ultrasound predictors in premenarcheal girls

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
We found a close correlation between thelarche and internal genital maturation on pelvic ultrasound, paralleling Tanner breast stages and supporting the concept of correlated external and internal pubertal development. Abstract Introduction Thelarche is often the first sign of puberty initiation in girls.
