Taxonomic Updates of Thismia pseudomelanomitra (Thismiaceae) Reveal an Old Acquaintance From the Ecuadorian Amazon

Feddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT The Amazon Basin is home to the world's greatest terrestrial biodiversity, but many plant groups remain poorly studied. One example is the mycoheterotrophic genus Thismia (Thismiaceae), which is notable for its highly specialized floral morphology and ephemeral life cycles, making it difficult to detect in the field and limiting its ...

Pubertal timing and incident uterine cancer in the Sister Study cohort

International Journal of Cancer, Volume 158, Issue 11, Page 2841-2852, 1 June 2026.
What's new? Younger age at menarche is an established risk factor for uterine cancer. Age at onset of breast development (thelarche), the earliest marker of pubertal estrogen exposure unopposed by progesterone, may also be relevant to uterine cancer risk, but this association has not been explored. Using data from the US prospective Sister Study cohort,

∆FOSB in the Nucleus Accumbens Core Is Required for Increased Anxiety, but Not Decreased Social Motivation, Following Estrogen Withdrawal in Female Mice

Genes, Brain and Behavior, Volume 25, Issue 3, June 2026.
In female mice, estrogen withdrawal following a hormone‐simulated pseudopregnancy is associated with increased levels of ∆FOSB in the Nucleus Accumbens Core and increased anxiety behaviors. However, using viral‐mediated expression of ∆JUND to decrease ∆FOSB‐mediated transcription in the Nucleus Accumbens Core prevents the increase in anxiety following ...

Vaginal Microbiota and Ovarian Cancer: A New Frontier in Immunomodulation and Diagnosis

Immunology, Volume 178, Issue 2, Page 209-217, June 2026.
Microbial imbalance, dysbiosis, plays a role in ovarian carcinogenesis by interacting with the immune system and altering inflammatory pathways, notably Th17 pathways. In contrast, eubiosis, characterised by Lactobacillus dominance, protects against infections and maintains hormone metabolism.
