Minipuberty of human infancy – A window of opportunity to evaluate hypogonadism and differences of sex development? [PDF]
Annals of Pediatric Endocrinology & Metabolism, 2020 Activation of the hypothalamic-pituitary-gonadal (HPG) axis happens in 3 phases during life. The first phase is during fetal life and is only separated from the second phase, called minipuberty, by the high concentration of placental hormones at birth ...

Modelling hematopoiesis mediated by growth factors with applications to periodic hematological diseases [PDF]
, 2006 Hematopoiesis is a complex biological process that leads to the production and regulation of blood cells. It is based upon differentiation of stem cells under the action of growth factors.

, 2002 We consider growing spheres seeded by random injection in time and space. Growth stops when two spheres meet leading eventually to a jammed state. We study the statistics of growth limited by packing theoretically in d dimensions and via simulation in d ...

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors
Population Ecology, EarlyView.Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

A Drosophila RNAi library modulates Hippo pathway-dependent tissue growth
Nature Communications, 2016 Drosophila RNAi libraries are commonly used to perform large-scale functional genetics screens in vivo. Here the authors find that a subset of lines from the VDRC KK RNAi line cause false-positive enhancement of the Hippo pathway, and provide a strain ...

USP5-Beclin 1 axis overrides p53-dependent senescence and drives Kras-induced tumorigenicity
Nature Communications, 2022 Oncogene-induced senescence (OIS) occurs in premalignant lung adenomas, but infrequently in malignant adenocarcinomas. Here the authors show that USP5-Beclin 1 axis overcomes OIS in Kras-driven lung cancer by enhancing MDM2-mediated p53 degradation.
