Impact of the relationship between renal pedicles and tumors on surgical outcomes for non-high-risk abdominal neuroblastoma.

Purpose: To assess the impact of the relationship between renal pedicles and tumors on surgical outcomes in patients with non-high-risk abdominal neuroblastoma.

Methods: We retrospectively analyzed cases of neuroblastoma without metastasis treated at our hospital between March 2002 and December 2023. Cases in which surgical resection was performed were divided into three groups according to imaging findings at the time of diagnosis and before surgery: Group E (tumor encasing renal pedicles), Group C (tumor in contact with renal pedicles), and Group S (tumor separated from renal pedicles).

A cellulose synthase-like protein governs the biosynthesis of alkaloids.

Decades of research on the infamous antinutritional steroidal glycoalkaloids (SGAs) in Solanaceae plants have provided deep insights into their metabolism and roles. However, engineering SGAs in heterologous hosts has remained a challenge. We discovered that a protein evolved from the machinery involved in building plant cell walls is the crucial link in the biosynthesis of SGAs.

Development of a Ru-porphyrin-based supramolecular framework catalyst for styrene epoxidation.

A new microporous supramolecular-framework Ru(II)-porphyrin catalyst containing non-covalent interactions between pyrenylphenyl moieties at the -position of the porphyrin ring is synthesised and structurally characterised. This recyclable catalyst expedites styrene epoxidation more efficiently than homogeneous Ru-porphyrin catalytic systems.

Nationwide questionnaire survey on pediatric pancreatic tumors in Japan.

Background: Pediatric pancreatic tumors are rare and account for < 0.1% of all childhood cancers. The primary treatment for pancreatic tumors is surgical resection.
