Article Abstract
Objectives: To investigate the feasibility and efficacy of liver-specific magnetic resonance imaging (MRI) with gadolinium-containing contrast agent guidance for microwave ablation (MWA) of recurrent small hepatocellular carcinoma (HCC).
Materials And Methods: The Ethics Committee of the First Affiliated Hospital of Fujian Medical University approved this study. Eighteen patients presented with 30 recurrent small HCCs, at least one lesion per patient was undetectable on unenhanced MRI, but this was clearly demonstrated in the hepatobiliary phase after liver-specific MRI contrast agent administration. Gd-BOPTA (16 cases) or Gd-EOB-DTPA (2 cases) were injected half an hour before the procedure, and MWA was performed by percutaneous puncture of the target lesion with a magnetic resonance-compatible microwave antenna under 1.5 T MRI guidance.
Results: The technical success rate was 100%. The mean maximum diameter of the lesions was 9.7 ± 2.8 mm (5.0-15.4 mm). The mean follow-up time was 11.6 ± 4.7 months (range, 4-19 months), and no local recurrence was observed.
Conclusions: MWA of small HCCs guided by enhanced liver-specific MRI contrast agent is a safe and effective technique.

Image of "Power of Woman (Weibermacht)" and Plastic Surgery.

The Northern Renaissance motif of Weibermacht-the "power of woman"-depicted female beauty as a destabilizing force capable of undermining male authority, intellect, and divine order. These visual allegories, featuring figures such as Phyllis, Judith, and Delilah, warned of the dangers inherent in seductive appearance. Far from neutral, beauty was rendered as morally volatile, triggering cultural anxiety through its capacity to challenge patriarchal norms.

However, ear space (otogenic) infections are one of the atypical causes of LS and have been rarely reported. We present a case of a male in his 20s with a history of recurrent acute otitis media (RAOM) who presented with purulent ear discharge, fever, neck pain, and swelling for a week.

Conversion surgery is increasingly used for initially unresectable esophageal cancer patients responding to induction therapy. The integration of immune checkpoint inhibitors (ICIs) into standard chemotherapy regimens is expected to increase the number of patients undergoing this approach. However, ICIs can cause immune-related adverse events (irAEs), which are often difficult to diagnose in the postoperative setting.

Precision in controlling the microenvironment of nanospaces is a potent strategy for exploring architecture‒function relationships. Herein, a face-capped tetrahedral cage, featuring Pd‒Pd-bonded vertices, with a tailored nanospace surrounded by 12 ethyl units, was facilitated to adaptively accommodate a library of guests with different sizes and shapes, including C6 cyclic hydrocarbons, adamantane derivatives, S and P. This nanocavity can achieve strong binding with cyclohexane in non-aqueous media in contrast to reported structurally similar non--functionalized cages by an increase of four orders of magnitude.

Background: Chronic intestinal bleeding caused by vascular malformations is uncommon. Locating these small intestinal vascular malformations with precision during surgery remains a challenge. With the rapid development of digital subtraction angiography (DSA), the detection of small intestinal vascular malformations has become easier.
