Does menopause hormone therapy improve symptoms of depression? Findings from a specialized menopause clinic.

Objective: Depressive symptoms are commonly reported during the perimenopause and in the early postmenopausal years. Although menopausal hormone therapy (MHT) is considered the most effective treatment option for vasomotor symptoms, its effect on mood-related symptoms is less established. This study aims to assess interval change in depressive symptoms after initiation of MHT treatment in women seeking care at a Canadian specialized menopause clinic.

Identification of Novel/Rare Fusion Partners in Undifferentiated Mesenchymal Neoplasms.

Recurrent gene fusions (GFs) in translocated sarcomas are recognized as major oncogenic drivers of the disease, as well as diagnostic markers whose identification is necessary for differential diagnosis. is a 'promiscuous' gene that can fuse with many different partner genes, defining different entities among a broad range of mesenchymal neoplasms. Molecular testing of translocation traditionally relies on FISH assays with break-apart probes, which are unable to identify the fusion partner.

Direct reprogramming of non-limb fibroblasts to cells with properties of limb progenitors.

The early limb bud consists of mesenchymal limb progenitors derived from the lateral plate mesoderm (LPM). The LPM also gives rise to the mesodermal components of the flank and neck. However, the cells at these other levels cannot produce the variety of cell types found in the limb.

Early heart rate variability changes during acute fetal inflammatory response syndrome: An experimental study in a fetal sheep model.

Comparison of Early Postoperative Outcomes for Vaginal Anterior Sacrospinous Ligament Fixation with or without Transvaginal Mesh Insertion.

Pelvic organ prolapse affects one in three women, and cystocele accounts for 80% of the indications for surgery. Following the withdrawal of transvaginal mesh from the market, the objective of the present before-and-after study was to compare of the previous reference technique (Uphold (Boston Scientific, Marlborough, MA, USA) mesh insertion) with anterior sacrospinous ligament fixation with suturing in terms of the outcomes 2 months after surgery. We performed a retrospective, observational, before-and-after study at Lille University Medical Center (Lille, France) by including consecutive patients operated on between 2011 and 2018 for Uphold mesh insertion and between 2018 to 2020 for anterior sacrospinous ligament fixation.

Distributive Nd-to-Yb Energy Transfer within Pure [YbNdYb] Heterometallic Molecules.

Facile access to site-selective hetero-lanthanide molecules will open new avenues in the search of novel photophysical phenomena based on Ln-to-Ln' energy transfer (ET). This challenge demands strategies to segregate efficiently different Ln metal ions among different positions in a molecule. We report here the one-step synthesis and structure of a pure [YbNdYb] () coordination complex featuring short Yb···Nd distances, ideal to investigate a potential distributive (, from one donor to two acceptors) intramolecular ET from one Nd ion to two Yb centers within a well-characterized molecule.

Failure of digit tip regeneration in the absence of Lmx1b suggests Lmx1b functions disparate from dorsoventral polarity.

Mammalian digit tip regeneration is linked to the presence of nail tissue, but a nail-explicit model is missing. Here, we report that nail-less double-ventral digits of ΔLARM1/2 mutants that lack limb-specific Lmx1b enhancers fail to regenerate. To separate the nail's effect from the lack of dorsoventral (DV) polarity, we also interrogate double-dorsal double-nail digits and show that they regenerate.
