The Role of Vaginal Oestrogen Therapy in Postmenopausal Women With Pelvic Organ Prolapse: Does It Have Any Impact on Perioperative Outcomes? A Systematic Review of Randomised Controlled Trials

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Background Pelvic organ prolapse (POP) affects up to 50% of postmenopausal women, negatively impacting sexual function and quality of life. While surgery remains the primary treatment, increasing attention has been given to perioperative vaginal oestrogen therapy and its potential impact on surgical outcomes.

Mapping replication dynamics in Trypanosoma brucei reveals a link with telomere transcription and antigenic variation

eLife, 2016
Survival of Trypanosoma brucei depends upon switches in its protective Variant Surface Glycoprotein (VSG) coat by antigenic variation. VSG switching occurs by frequent homologous recombination, which is thought to require locus-specific initiation. Here,

Response to equine cardiac adverse events during sports

Equine Veterinary Education, EarlyView.
Summary Cardiac adverse events and sudden death are a feared scenario for equine veterinarians, with serious consequences for animal health, riders' safety and the social licence to operate equestrian sports. The response to equine cardiac adverse events (CAEs) during sports is poorly defined.

Optimizing Inertia Estimation in Virtual Synchronous Generators With MMC-Based Proportional Integral and Model Predictive Control Strategies

IEEE Access
The increasing integration of renewable energy sources influences the power grid, resulting in a reduction in the traditional inertia supplied by synchronous generators.

VSG Control Strategy Incorporating Voltage Inertia and Virtual Impedance for Microgrids

Energies, 2020
Virtual synchronous generator (VSG) control lacks voltage inertia and powerful decoupling capabilities. The voltage of the distributed generator (DG) unit controlled by the VSG will be easily affected by power fluctuations and high-frequency noise, and ...

Morphofunctional effects of captivity on the microanatomy of the talus bone in a wild ungulate (Sus scrofa)

Journal of Anatomy, EarlyView.
Our study explores the plastic changes induced by captivity on the microanatomy of the talus of wild boars, revealing denser bone with tighter trabecular networks but a lower relative maximum thickness of compact bone. These plastic adaptations can serve to detect early processes of domestication in the archaeological record.

Trypanosoma brucei ATR Links DNA Damage Signaling during Antigenic Variation with Regulation of RNA Polymerase I-Transcribed Surface Antigens

Cell Reports, 2020
Summary: Trypanosoma brucei evades mammalian immunity by using recombination to switch its surface-expressed variant surface glycoprotein (VSG), while ensuring that only one of many subtelomeric multigene VSG expression sites are transcribed at a time ...

Analysis and Optimization Strategy of Active Power Dynamic Response for VSG under a Weak Grid

Energies, 2023
A virtual synchronous generator (VSG) has a good adaptability to the weak grid but its grid-connected active power (GCAP) has the problem of a slow dynamic response under the active power command step.

Sharing VSG Operation with Synchronous Generator

Journal of Physics: Conference Series, 2022
Abstract While several synchronous generators (SGs) are substituted through virtual synchronous generators (VSGs), some SGs remain in today’s microgrids. And the majority of the research assumes that VSG mimics SG characteristics, allowing it to function in parallel among SGs. However, few studies have gone to great lengths to study this

Trypanosomal MICOS Is Assembled on Non‐Respiring Mitochondrial Crista Precursors and Associates With Two Integral Microproteins

Molecular Microbiology, EarlyView.
The mitochondrial membrane‐shaping machinery MICOS is assembled surprisingly early during the life cycle of Trypanosoma brucei, before the mitochondrion acquires its mature architecture or full respiratory capacity. Our study also identifies two previously uncharacterized proteins associated with MICOS, providing new insight into the early organization
