Estradiol affects the expression of essential molecular factors involved in luteinizing hormone secretion in the plains vizcacha.

The plains vizcacha is a rodent that shows reactivation of the hypothalamic-pituitary-ovary (HPO) axis activity at mid-gestation. This process is enabled by the secretion of hypothalamic gonadotropin-releasing hormone (GnRH) at mid-gestation, followed by follicle-stimulating hormone (FSH) and luteinizing hormone (LH) secretion. However, a decrease in the pituitary GnRH receptor (GnRHR) expression is concomitantly determined.

Vaccinations in children of non-European origin: The Vax4globe survey.

Background: An equitable immunization coverage to "leave no one behind" is one of the World Health Organization Sustainable Development Goals. However, disparities in vaccination coverage exist. The present study aims to investigate vaccine attitude of non-European parents living in Italy and those factors affecting vaccine uptake and equity.

Long-term mandibular growth in patients with airway obstruction treated with mandibular distraction.

Congenital craniofacial malformations play an important role in upper airway obstruction. One of the main causes is mandibular hypoplasia which is present in the pierre robin sequence. Mandibular distraction osteogenesis (MDO) is one of the most commonly used treatments for the resolution of upper airway obstruction in patients that do not respond to a conservative treatment.

L1CAM expression in human gastrointestinal tract development: From tongue to colon-rectum.

Background: L1CAM (L1 cell adhesion molecule) is a member of the L1 family of neural adhesion molecules, involved in the development of multiple organs and tissues, including kidneys, the enteric nervous system, and adrenal glands. The aim of this study was to analyze, at the immunohistochemical level, the expression of L1CAM in the human tongue, parotid glands, and the different segments of the gastrointestinal tract during human development.

Design And Method: Immunohistochemical analysis for L1CAM was performed in the human tongue, parotid glands, and in the different segments of the gastrointestinal tract during development, starting from the 8th up to the 32nd week of gestation.

Persistently expressed human chorionic gonadotropin induces premature luteinization and progressive alterations on the reproductive axis in female mice.

The hypothalamic-pituitary-gonadal axis plays a fundamental role in the endocrine regulation of the reproductive function in mammals. Any change in the function of the participating hormones or their receptors can lead to alterations in sexual differentiation, the onset of puberty, infertility, cancer development, and other dysfunctions. In this study, we analyzed the influence of persistently elevated levels of the human chorionic gonadotropin hormone (hCG), a powerful agonist of pituitary luteinizing hormone (LH), on the reproductive axis of female mice.
