Time-Resolved Diamond Magnetic Microscopy of Superparamagnetic Iron-Oxide Nanoparticles.

Superparamagnetic iron-oxide nanoparticles (SPIONs) are promising probes for biomedical imaging, but the heterogeneity of their magnetic properties is difficult to characterize with existing methods. Here, we perform wide-field imaging of the stray magnetic fields produced by hundreds of isolated ∼30 nm SPIONs using a magnetic microscope based on nitrogen-vacancy centers in diamond. By analyzing the SPION magnetic field patterns as a function of the applied magnetic field, we observe substantial field-dependent transverse magnetization components that are typically obscured with ensemble characterization methods.

Transvaginal natural orifice transluminal endoscopic surgery for early-stage ovarian cancer and borderline ovarian tumors: a case series.

Introduction: Surgery is the cornerstone of ovarian cancer treatment. Transvaginal natural orifice transluminal endoscopic surgery (vNOTES) is a novel, minimally invasive technique that is gaining interest in gynecological oncology. However, its use in ovarian cancer is still limited, with only a few cases reported.

Safety and efficacy of transvaginal natural orifice endoscopic surgery (vNOTES) for gynecologic procedures in the elderly: A case series of 119 consecutive patients.

Introduction: This study evaluates the feasibility and safety of Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) in patients aged ≥ 65, focusing on early surgical outcomes for benign and malignant gynecological conditions.

Methods: A total of 119 patients aged 65 and older who underwent vNOTES procedures at Valais Hospital from May 2020 to November 2024 were included. Data collected encompassed demographic characteristics, intraoperative details (e.

No evidence of a visual testing effect for novel, meaningless objects.

The testing effect is a well-established phenomenon in which memory is better for information that has been enhanced through practice tests rather than through restudying. However, this phenomenon has been studied almost exclusively with verbal or semantically meaningful material. We explored whether the testing effect holds for abstract visual material that lacks both meaning and verbal labels.

ChatGPT's Performance in Spinal Metastasis Cases-Can We Discuss Our Complex Cases with ChatGPT?

The integration of artificial intelligence (AI), particularly large language models (LLMs) like ChatGPT-4, is transforming healthcare. ChatGPT's potential to assist in decision-making for complex cases, such as spinal metastasis treatment, is promising but widely untested. Especially in cancer patients who develop spinal metastases, precise and personalized treatment is essential.
