Factors influencing medical students' interest in obstetrics and gynecology: a longitudinal study on career preferences.

Introduction: Choosing a medical specialty is a pivotal moment in a physician's career, shaped by personal interests, clinical experiences, and professional interactions. Obstetrics and gynecology (OB-GYN) offers a unique blend of surgical and medical care focused on women's health. Given the growing demand for OB-GYN specialists, understanding the factors that influence students' decisions is essential for workforce planning.

Blobby is a synaptic active zone assembly protein required for memory in Drosophila.

At presynaptic active zones (AZs), scaffold proteins are critical for coordinating synaptic vesicle release and forming essential nanoarchitectures. However, regulatory principles steering AZ scaffold assembly, function, and plasticity remain insufficiently understood. We here identify an additional Drosophila AZ protein, "Blobby", essential for proper AZ nano-organization.

DNA end sensing and cleavage by the Shedu anti-phage defense system.

The detection of molecular patterns associated with invading pathogens is a hallmark of innate immune systems. Prokaryotes deploy sophisticated host defense mechanisms in innate anti-phage immunity. Shedu is a single-component defense system comprising a putative nuclease SduA.

Diagnoses of postpartum urinary retention using next-generation non-piezo ultrasound technology: assessing the accuracy and benefits.

Postpartum urinary retention has a wide range of publicized incidences, likely caused by frequent misdiagnosis of this puerperal complication. Especially covert postpartum urinary retention has a high number of missed diagnoses due to the lack of symptoms and the time-extensive diagnostics via ultrasound, leading to no treatment and no appropriate follow-up. To simplify the diagnosis and establish a screening tool we analyzed the application of portable handheld-ultrasound devices  (PUD) as used in Point-of-care diagnostics in comparison to established standard ultrasound devices (SUD).
