Floral specialization for beetle pollination and its implications for pollen dispersal in an African orchid

American Journal of Botany, EarlyView.
Abstract Premise Pollination by beetles is relatively rare in orchids, and this has been attributed to the clumsy behavior of beetles being unsuitable for the precise pollen transfer mechanisms that characterize the orchid family. We investigated floral specialization for beetle pollination in the rare fire‐dependent South African orchid Disa elegans ...

Progestin-primed ovarian stimulation for oocyte cryopreservation in patients with nonmedical indications: a case–control study

Reproductive Biology and Endocrinology
Background The PPOS (Progestin Primed Ovarian Stimulation) protocol has been evaluated and has proved its effectiveness in preventing the LH (luteinizing hormone) surge.

Co‐flowering with congeners does not affect buzz‐pollinator specialization and pollination performance in Rhexia mariana, but does affect floral trait variance

American Journal of Botany, EarlyView.
Abstract Premise Pollinator‐mediated plant‐plant interactions may be negative (i.e., competition, reproductive interference) or positive (i.e., facilitation). Especially when co‐flowering with close relatives (e.g., congeners), negative interactions through reproductive interference may be strong and result in floral trait divergence and increased ...

TBX3‐ Related Disorder

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous pathogenic variants in TBX3 cause Ulnar‐Mammary syndrome (UMS). The phenotype is classically characterized by upper limb defects, apocrine/mammary gland hypoplasia, hypogonadism, and various midline defects. However, the clinical spectrum is highly variable, and some individuals may present with a mild or atypical presentation ...

A scoping review of non‐binary research in “Australian” social sciences: Community, solidarity, resilience and resisting marginalisation

Australian Journal of Social Issues, EarlyView.
Abstract Non‐binary and genderqueer identities are increasingly discussed in public discourse and academia, but there remains a dearth of academic literature centred on non‐binary people's lives and experiences. When non‐binary people are included in research, it is frequently as an additive to explorations of trans identities and subsumed under the ...

Evidence of apoptosis as an early event leading to cyclophosphamide-induced primordial follicle depletion in a prepubertal mouse model

Frontiers in Endocrinology
IntroductionThe mechanisms leading to ovarian primordial follicle depletion following gonadotoxic chemotherapy with cyclophosphamide and other cytotoxic drugs are currently understood through two main explanatory theories: apoptosis and over-activation ...
