The patient was a 21-year-old man with a shadow on a chest roentgenogram taken during a medical checkup. According to blood testing, thoracoabdominal computed tomography, head magnetic resonance imaging, and lung tumor biopsy, we diagnosed a primary retroperitoneal germ cell tumor with multiple lung and brain metastases. Induction chemotherapy (4 courses of Bleomycin, Etoposide and Cisplatin) was started immediately.

However, catalyst deactivation caused by the poisoning of catalytic sites by analytes and/or catalyzed products remains a challenge. This study highlights the underestimated role of van der Waals interactions between hydrophobic aliphatic alkyl chains and hydrophilic ZnO surfaces in mitigating catalyst deactivation during aliphatic aldehyde sensing.
View Article and Find Full Text PDFShoot branching is a critical determinant of plant architecture and a key factor affecting crop yield. The shoot branching involves two main processes: axillary meristem formation and subsequent bud outgrowth. While considerable progress has been made in elucidating the genetic mechanisms underlying the latter process, our understanding of the former process remains limited.

- The study highlights the importance of using strong metal oxide adhesion layers (like NiO, TiO, TiO, ZnO, and WO) on quartz crystal microbalance (QCM) humidity sensors made from cellulose nanofibers (CNF) to improve their sensitivity and stability.
- Metal oxide layers helped maintain the stability of CNF films in high-humidity conditions, outperforming traditional adhesion methods like polyethylenimine.
- The research showed that QCM sensitivity decreased with increased water wettability of the metal oxide surfaces, establishing a link between the structure of CNF films and their adhesive performance based on surface properties.
Objective: To elucidate the incidence, presentation timing, and determinants of adulthood neourethral strictures after childhood hypospadias repair, using data from a database derived from a single procedure performed by a single surgeon.
Methods: Pediatric patients with hypospadias who underwent staged surgery using a foreskin-derived neourethra served as the Denominator population. Clinical data from adult neourethral stricture patients who re-visited us were analyzed.
