Unraveling Delayed Puberty: A Rare Case of Congenital Hypogonadotropic Hypogonadism Masked by Celiac Disease and Plummer–Vinson Syndrome

Clinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder that results in delayed puberty and infertility due to impaired secretion of gonadotropin‐releasing hormone (GnRH). Here, we present a case of a 25‐year‐old male with a known history of Plummer–Vinson syndrome and celiac disease, who presented with the chief complaints of easy ...

Coordinated Transcriptomic and Epigenetic Approach Reveals Molecular Features Underlying Natural Mating Ability in Captive Male Giant Pandas

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We investigated the molecular mechanisms underlying natural mating ability in captive male giant pandas using integrated transcriptomic and DNA methylation analyses. Our findings highlight key gene expression and epigenetic differences associated with reproductive behavior, offering novel insights for optimizing captive breeding and conservation ...

Within‐ and Across‐Generational Effects of Temperature: Exposure of Manduca sexta Larvae to Heat Stress Impacts Future Reproduction and Offspring Development

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We assessed how an acute heat shock event experienced at two different points in Manduca sexta larval development (early and late) impacted adult performance and fitness traits and whether thermal exposure of parents elicited plastic changes in offspring traits.
