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.

Catalysis-based electrical sensing of volatile organic compounds on metal oxide surfaces is a powerful method for molecular discrimination. 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.

Shoot 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.

Article Synopsis
  • 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.

Article Synopsis
  • Plant stems consist of nodes and internodes that have distinct functions for solute exchange and growth, yet their boundaries are unclear.
  • In rice, researchers discovered that specific genes help control node formation and promote internode development by inhibiting genes associated with leaf growth and other node features.
  • This study suggests that the organization of these gene groups is unique to seed plants and highlights the evolutionary divergence of nodes and internodes.

To maintain a beneficial concentration of eicosapentaenoic acid (EPA), the efficient conversion of its precursor, α-linolenic acid (α-LA), is important. Here, we studied the conversion of α-LA to EPA using ICR and C57BL/6 mice. A single dose of perilla oil rich-in α-LA or free α-LA had not been converted to EPA 18 h following administration.

Root hairs play vital roles in plant growth since they enable the efficient absorption of water and nutrients from the soil. Recent advances in research have provided a deeper understanding of the molecular genetic mechanisms underlying root hair differentiation. () and its four homologs, which belong to the gene family and encode R3 MYB transcription factors, play central roles in root hair differentiation.

is one of the predominant oral bacteria in humans. However, this bacterium is enriched in colorectal cancer (CRC) tissues and may be involved in CRC development. Our previous research suggested that is present in CRC tissues originating from the oral cavity using a traditional strain-typing method [arbitrarily primed polymerase chain reaction (AP-PCR)].

Artificially programming a sequence of organic-metal oxide multilayers (superlattices) by using atomic layer deposition (ALD) is a fascinating and challenging issue in material chemistry. However, the complex chemical reactions between ALD precursors and organic layer surfaces have limited their applications for various material combinations. Here, we demonstrate the impact of interfacial molecular compatibility on the formation of organic-metal oxide superlattices using ALD.

The shoot and root system architectures are fundamental for crop productivity. During the history of artificial selection of domestication and post-domestication breeding, the architecture of rice has significantly changed from its wild ancestor to fulfil requirements in agriculture. We review the recent studies on developmental biology in rice by focusing on components determining rice plant architecture; shoot meristems, leaves, tillers, stems, inflorescences and roots.

Atomic layer deposition (ALD) offers excellent controllability of spatial uniformity, film thickness at the Angstrom level, and film composition even for high-aspect-ratio nanostructured surfaces, which are rarely attainable by other conventional deposition methodologies. Although ALD has been successfully applied to various substrates under open-top circumstances, the applicability of ALD to confined spaces has been limited because of the inherent difficulty of supplying precursors into confined spaces. Here, we propose a rational methodology to apply ALD growths to confined spaces (meter-long microtubes with an aspect ratio of up to 10 000).

Article Synopsis
  • Social stress in adult mice increased blood corticosterone levels after 2 days, disrupted liver metabolism pathways at 30 days, and raised the risk of becoming overweight at 90 days.
  • A study on male BALB/c mice revealed that younger mice (2 months old) had elevated corticosterone after 2 days of stress, but levels returned to normal afterward, while older mice (14 and 26 months) showed a decrease in liver gene expression related to stress response.
  • The findings suggest that as mice age, their liver's response to stress becomes less effective, highlighting the impact of aging on health and stress reactions.

A 60-year-old man visited our hospital to treat a large cystic mass in the pelvis which had been found by abdominal ultrasonography in December 201X. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a multilocular cyst with a maximum diameter of about 10 cm. CT-guided drainage and sclerotherapy with minocycline reduced the size of tumor by 40%, but symptoms such as difficulty of defecation and urinary frequency appeared a year and a half later due to re-enlargement of the cysts.

fabrication of well-defined bridging nanostructures is an interesting and unique approach to three-dimensionally design nanosensor structures, which are hardly attainable by other methods. Here, we demonstrate the significant effect of edge-topological regulation on fabrication of ZnO bridging nanosensors. When employing seed layers with a sharp edge, which is a well-defined structure in conventional lithography, the bridging angles and electrical resistances between two opposing electrodes were randomly distributed.

D-type cyclins (CYCDs) are involved in a wide range of biological processes, as one of the major regulators of cell cycle activity. In Arabidopsis (Arabidopsis thaliana), three members of CYCD3 subgroup genes play important roles in plant development such as leaf development and branch formation. In rice (Oryza sativa), there is only one gene (OsCYCD3;1) belonging to the CYCD3 subgroup; its function is unknown.

Humidity and moisture effects, frequently called water poisoning, in surroundings are inevitable for various molecular sensing devices, strongly affecting their sensing characteristics. Here, we demonstrate a water-selective nanostructured dehumidifier composed of ZnO/TiO/CaCl core-shell heterostructured nanowires for molecular sensing spaces. The fabricated nanostructured dehumidifier is highly water-selective without detrimental adsorptions of various volatile organic compound molecules and can be repeatedly operated.

We propose a rational strategy to fabricate thermally robust, highly integrated molecular and gas sensors utilizing a lateral SnO nanofilm channel geometry on a 1024 crossbar sensor array. The proposed lateral channel geometry substantially suppresses the detrimental effects of parasitic interconnect wire resistances compared with those of a conventional vertical sandwich-type crossbar array because of its excellent resistance controllability. A conductive oxide top-contact electrode on the lateral SnO nanofilm channel enhances the thermal stability at temperatures of up to 500 °C in ambient air.
