Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Oviductal estrogen receptor α signaling prevents protease-mediated embryo death
eLife, 2015 Development of uterine endometrial receptivity for implantation is orchestrated by cyclic steroid hormone-mediated signals. It is unknown if these signals are necessary for oviduct function in supporting fertilization and preimplantation development ...

Advanced Science, EarlyView.This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

HMGB2–RAD21 Axis Promotes Fibro/Adipogenic Progenitor Proliferation and Regulates Fat Infiltration
Advanced Science, EarlyView.This study constructed the first developmental atlas of embryonic skeletal muscle fibro/adipogenic progenitors (FAPs) and identified an HMGB2+ FAPs subpopulation that regulates FAP pool size and muscle homeostasis. HMGB2 directly targets the RAD21 promoter, and its knockout significantly reduces FAP numbers, thereby lowering the potential for ...

Advanced Science, EarlyView.IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

Sterility in breeding sows as a consequence of reproductive tract diseases [PDF]
Veterinarski Glasnik, 2002 In this paper we examined the effects of certain pathological conditions on the sterility of breeding sows. Pathomorphological investigations were performed on 185 reproductive organs. We analyzed the reasons for elimination from local records.

Function of Bilateral Oviducts in Double Oviduct Hens Following Surgery
Poultry Science, 1988 A double oviduct line of Rhode Island Red chickens has been maintained as a closed flock at the Wisconsin Experiment Station since 1970. Sixty-four percent of the stock reared during the 3-yr study period had complete left and right oviducts. Experiments were designed to determine whether the right oviduct of double oviduct hens was functional.
