Clinical implication of metastasis in the second most radioactive sentinel lymph node with nonmetastatic most radioactive node in patients with breast cancer.

Background: Sentinel lymph node biopsy (SNB) using radioisotopes is a standard method for assessing axillary lymph node status in patients with breast cancer. Although preoperative lymphoscintigraphy can estimate the number of sentinel lymph nodes (SNs), multiple radioactive SNs are often identified, even when lymphoscintigraphy reveals only one SN. Importantly, metastases are not always observed in the most radioactive SN (hottest SN).

OBP2A regulates epidermal barrier function and protects against cytotoxic small hydrophobic molecules.

The skin is constantly exposed to environmental sensory stimuli, which may include harmful volatiles and small hydrophobic molecules. However, the skin's protective mechanism against the latter agents is unclear. Here, we demonstrate that odorant binding protein 2A (OBP2A) protects epidermal keratinocytes against cytotoxic small hydrophobic molecules.

Association of Plasma Nestin With Response to Immune Checkpoint Inhibitors Combined With Chemotherapy in Extensive-stage Small-cell Lung Cancer: A Pilot Study.

Background/aim: Nestin, an intermediate filament protein expressed in stem/progenitor cells of the developing central nervous system, is involved in the progression and poor prognosis of various malignancies. Difficulties in small-cell lung cancer (SCLC) tissue biopsy reduce the accuracy of immunohistochemistry analyses; therefore, evaluating nestin in blood samples is preferred in clinical practice. This study examined the clinical significance of plasma nestin levels in SCLC.

Transvenous embolization of a Borden III middle cranial fossa dural arteriovenous fistula through the vein of Trolard and superficial middle cerebral vein: A technical case report.

Endovascular treatment for isolated dural arteriovenous fistula (DAVF) in the middle cranial fossa (MCF) with pure cortical venous drainage poses challenges, including the absence of a safe access route for transvenous embolization (TVE) and the risk of ischemia to neuro feeding vessels and dangerous anastomosis at the sphenoid wing. Therefore, surgical treatment involving direct blockage of venous reflux via craniotomy is typically preferred. We describe the case of a 63-year-old woman presented with generalized seizures and was diagnosed with a Borden III left MCF-DAVF.
