Single-cell atlas of the pregnant equine endometrium before and after implantation.

Embryo implantation in the mare occurs just over one month after fertilization, coinciding with the production of chorionic gonadotropin. The factors that regulate this late implantation in the mare, and whether they are unique to horses or shared with more invasive embryo implantation in other species, remain poorly understood. This study aimed to determine and compare the transcriptome and subpopulations of endometrial cells before and after embryo implantation in the horse.

High-Intensity Interval Training, but Not Whole-Body Cryostimulation, Affects Bone-Mechanosensing Markers and Induces the Expression of Differentiation Markers in Osteoblasts Cultured with Sera from Overweight-to-Obese Subjects.

Although there have been some clinical observations made, the mechanistic effects on bone metabolism of whole-body cryostimulation and high-intensity interval training (HIIT), either alone or in combination, are still debated. Here, we have investigated their effects on circulating osteo-immune and bone metabolic markers (osteopontin, osteocalcin, sclerostin, dikkopf-related protein 1, and fibroblast-growth factor 23) and their potential effects on osteoblast differentiation and function, , by treating SaOS-2 osteoblast-like cells with the sera obtained from the subjects who had undergone the different interventions or untreated control subjects. Sixty-seven inactive, overweight-to-obese participants (body mass index = 31.

Properties of biodegradable polymer coatings with hydroxyapatite on a titanium alloy substrate.

: Titanium alloys are among the most widely used materials in medicine, especially in orthopedics. However, their use requires the application of an appropriate surface modification method to improve their properties. Such methods include anodic oxidation and the application of polymer coatings, which limit the release of alloying element ions.

Rationale for the Initiation, Outcomes, and Characteristics of Chemotherapy Following CDK4/6 Inhibitors in Breast Cancer: A Real-World Cohort Study.

The standard therapy for hormone-receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer includes the use of cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) with endocrine therapy. The optimal post-CDK4/6i treatment sequence is unclear. This cohort study evaluated the initiation, characteristics, and outcomes of chemotherapy following CDK4/6i-based treatment.
