Efficacy of Paclitaxel and Cetuximab in Recurrent/Metastatic Oral Cancer Cases Following Superselective Intraarterial Chemoradiotherapy: A Retrospective Cohort Study.

Background/aim: The therapeutic efficacy of the paclitaxel (PTX) + cetuximab (Cmab) combination regimen was investigated in patients with recurrence or metastasis after superselective intraarterial chemoradiotherapy (SSIACRT) for oral cancer, and the safety was retrospectively examined.

Patients And Methods: All enrolled patients with advanced oral cancer or who had refused surgery over 10 years from December 2012 to December 2022 underwent SSIACRT for 6 to 9 weeks [cisplatin (CDDP): total 160-630 mg/m and radiotherapy: total 50-70 Gy]. Nine cases (tongue cancer, maxillary gingival cancer, and mandibular gingival cancer; three cases each) were subjected to PTX + Cmab therapy.

Development of engineered IL-36γ-hypersecreting Lactococcus lactis to improve the intestinal environment.

Interleukin (IL) 36 is a member of the IL-1-like proinflammatory cytokine family that has a protective role in mucosal immunity. We hypothesized that mucosal delivery of IL-36γ to the intestine would be a very effective way to prevent intestinal diseases. Here, we genetically engineered a lactic acid bacterium, Lactococcus lactis, to produce recombinant mouse IL-36γ (rmIL-36γ).

Developing long bones respond to surrounding tissues by trans-pairing of periosteal osteoclasts and endocortical osteoblasts.

Developing long bones alter their shape while maintaining uniform cortical thickness via coordinated activity of bone-forming osteoblasts and bone-resorbing osteoclasts at periosteal and endosteal surfaces, a process we designate trans-pairing. Two types of trans-pairing shift cortical bone in opposite orientations: peri-forming trans-pairing (peri-t-p) increases bone marrow space and endo-forming trans-pairing (endo-t-p) decreases it, via paired activity of bone resorption and formation across the cortex. Here, we focused on endo-t-p in growing bones.

Glycan-shielded homodimer structure and dynamical features of the canine distemper virus hemagglutinin relevant for viral entry and efficient vaccination.

Canine distemper virus (CDV) belongs to morbillivirus, including measles virus (MeV) and rinderpest virus, which causes serious immunological and neurological disorders in carnivores, including dogs and rhesus monkeys, as recently reported, but their vaccines are highly effective. The attachment glycoprotein hemagglutinin (CDV-H) at the CDV surface utilizes signaling lymphocyte activation molecule (SLAM) and Nectin-4 (also called poliovirus-receptor-like-4; PVRL4) as entry receptors. Although fusion models have been proposed, the molecular mechanism of morbillivirus fusion entry is poorly understood.

IL-33-ST2 signaling in fibro-adipogenic progenitors alleviates immobilization-induced muscle atrophy in mice.

Background: The regenerative and adaptive capacity of skeletal muscles reduces with age, leading to severe disability and frailty in the elderly. Therefore, development of effective therapeutic interventions for muscle wasting is important both medically and socioeconomically. In the present study, we aimed to elucidate the potential contribution of fibro-adipogenic progenitors (FAPs), which are mesenchymal stem cells in skeletal muscles, to immobilization-induced muscle atrophy.

Nursing students' self-assessed level of nursing skills at the time of graduation in a Japanese University: A retrospective observational study.

Objective: This study aimed to clarify nursing students' self-assessed levels of nursing skills at a nursing university at graduation and discuss how education and clinical experiences for students and post-licensure nurses should be improved, especially focusing on oncology nursing.

Methods: The study population comprised fourth-year students from 2017 to 2019 at the Faculty of Health Science and Nursing, Juntendo University, who had completed all stipulated clinical placements. The Japanese government determined 141 nursing skills and their target levels.

Broadened quantum critical ground state in a disordered superconducting thin film.

A superconductor-insulator transition (SIT) in two dimensions is a prototypical quantum phase transition (QPT) with a clear quantum critical point (QCP) at zero temperature (T = 0). The SIT is induced by a field B and observed in disordered thin films. In some of weakly disordered or crystalline thin films, however, an anomalous metallic (AM) ground state emerges over a wide B range between the superconducting and insulating phases.

Designing a muon scattering scanner for nuclear debris measurement.

Removal of fuel debris is planned to start at Unit 2 of the Fukushima Daiichi Nuclear Power Plant. During the removal, it is desirable to distinguish fuel debris from radioactive wastes and to sort the fuel debris accordingly to the amounts of nuclear material contained. Muon scattering tomography invented at Los Alamos in the early 2000s is highly sensitivity to high-atomic-number materials such as uranium.

A Common Marmoset Model of Mother-Infant Intervention for Breastfeeding Disorders in the Presence of Paternal Inhibition and Maternal Neglect.

Parents' psychological stress during the perinatal and neonatal periods continues to increase in an environment of declining birthrates, aging populations, and shrinking family sizes. The increase in child abuse and neglect cases, most likely by inexperienced and insufficiently knowledgeable parents, necessitates education on childcare and intervention techniques in nursing and midwifery training. In particular, attachment formation early in life between mother and infant is crucial.

Near-infrared light-inducible Z-scheme overall water-splitting photocatalyst without an electron mediator.

We facilely prepared a solid-state heterojunction photocatalyst in which silver vanadium oxide (AgVO) and zinc rhodium oxide (ZnRhO) as oxygen and hydrogen evolution photocatalysts, respectively, were directly connected to generate AgVO/ZnRhO. AgVO/ZnRhO photocatalyzed overall pure-water splitting without any electron mediator under irradiation with near-infrared light at wavelengths of up to 910 nm. The key points are that the conduction bottom potential of AgVO is almost the same as the valence band top potential of ZnRhO, and that the bandgaps of AgVO and ZnRhO are 1.

Kinematics of lateral tongue-pushing movement in coordination with masticatory jaw movement: An anteroposterior projection videofluorographic study.

Objective: During the mastication of solid food, the tongue pushes the bolus laterally to place it onto occlusal surfaces as the jaw is opened. This movement is referred to as tongue-pushing (TP). TP has an important role in efficient chewing, but its kinematic mechanisms remain unclear.

Eribulin mesylate induces bone mass loss by promoting osteoclastic bone resorption in mice.

Over the past few decades, the clinical outcomes of patients with cancer have significantly improved mostly owing to the development of effective chemotherapeutic treatments. However, chronic health conditions such as bone mass loss and risk of fragility fractures caused by chemotherapy have also emerged as crucial issues in patients treated for cancer. In this study, we aimed to understand the effect of eribulin mesylate (ERI), a microtubule-targeting agent currently used to treat metastatic breast cancer and certain subtypes of advanced sarcomas, on bone metabolism in mice.

Nicotinamide-N-methyltransferase regulates lipid metabolism via SAM and 1-methylnicotinamide in the AML12 hepatocyte cell line.

Nicotinamide-N-methyltransferase (NNMT) is an enzyme that consumes S-adenosyl-methionine (SAM) and nicotinamide (NAM) to produce S-adenosyl-homocysteine (SAH) and 1-methylnicotinamide (MNAM). How much NNMT contributes to the quantity regulation of these four metabolites depends on whether NNMT is a major consumer or producer of these metabolites, which varies among various cellular contexts. Yet, whether NNMT critically regulates these metabolites in the AML12 hepatocyte cell line has been unexplored.

Serum amyloid alpha 1-2 are not required for liver inflammation in the 4T1 murine breast cancer model.

Cancers induce the production of acute phase proteins such as serum amyloid alpha (SAA) in the liver and cause inflammation in various host organs. Despite the well-known coincidence of acute phase response and inflammation, the direct roles of SAA proteins in inflammation in the cancer context remains incompletely characterized, particularly . Here, we investigate the significance of SAA proteins in liver inflammation in the 4T1 murine breast cancer model.

Impact of squid predation on juvenile fish survival.

Predation is a major source of mortality during the early life stages of marine fishes; however, few studies have demonstrated its impact-especially that of squid predation-on survival processes. Here, we examined the feeding habits and predation impacts of swordtip squid on a major prey fish, juveniles of jack mackerel, in the East China Sea. Otoliths of the juveniles extracted from the squid stomach were used to reconstruct the age-length relationship and the growth trajectory of the consumed juveniles, and they were compared to those of juveniles collected with a net using a newly developed statistical framework.

Remote solid cancers rewire hepatic nitrogen metabolism via host nicotinamide-N-methyltransferase.

Cancers disrupt host homeostasis in various manners but the identity of host factors underlying such disruption remains largely unknown. Here we show that nicotinamide-N-methyltransferase (NNMT) is a host factor that mediates metabolic dysfunction in the livers of cancer-bearing mice. Multiple solid cancers distantly increase expression of Nnmt and its product 1-methylnicotinamide (MNAM) in the liver.

Near-wall velocities of particles suspended in shear flow and a streamwise electric field.

Particles with a diameter of ∼0.5 µm in a dilute (volume fractions φ  < 4 × 10 ) suspension assemble into highly elongated structures called "bands" under certain conditions in combined Poiseuille and electroosmotic flows in opposite directions through microchannels at particle-based Reynolds numbers Re  < < 1. The particles are first concentrated near, then form "bands" within ∼6 µm of, the channel wall.

Unlabelled: Watabe T, Abe M, Sako R, Suzuki H, Yoda M, Kawate N. Association between external ophthalmoplegia with diplopia due to brain injury and FIM motor items: a case-control study. Jpn J Compr Rehabil Sci 2021; 12: 58-63.

Observations of the near-wall accumulation of suspended particles due to shear and electroosmotic flow in opposite directions.

On the basis of previous studies, the particles in a dilute (volume fractions φ < 4 × 10 ) suspension in combined Poiseuille and electroosmotic "counterflow" at flow Reynolds numbers Re ≤ 1 accumulate, then assemble into structures called "bands," within ∼6 μm of the channel wall. The experimental studies presented here use a small fraction of tracer particles labeled with a different fluorophore from the majority "bulk" particles to visualize the dynamics of individual particles in a φ = 1.7 × 10  suspension.

Aging Aggravates the Progression of Muscle Degeneration After Rotator Cuff Tears in Mice.

Purpose: The purpose of this study was to evaluate the impact of aging on muscle degeneration after rotator cuff tear (RCT) in mice.

Methods: Young (12-week-old) and aged (50-to-60-week-old) female C57BL/6 mice were used (n = 29 for each group). The rotator cuff was transected, and the proximal humerus was removed to induce degeneration of the rotator cuff muscles.

ADAM10 partially protects mice against influenza pneumonia by suppressing specific myeloid cell population.

The influenza virus infection poses a serious health threat worldwide. Myeloid cells play pivotal roles in regulating innate and adaptive immune defense. A disintegrin and metalloproteinase (ADAM) family of proteins contributes to various immune responses; however, the role of a disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) in influenza virus infection remains largely unknown.

Quantitative evaluation of latent fingermarks with novel enhancement and illumination.

A variety of suspended silica and metal nanoparticles have been used over the last 20 years to enhance latent fingermarks. This study quantitatively evaluates enhancement of natural and sebum-enriched fingermarks from three adult subjects acquired with a consistent applied force on glass with a fingermark press using suspended commercially available polystyrene (PS) particles. Images of the enhanced fingermarks acquired with total internal reflection (TIR), or standard overhead white light (WL), illumination are compared with fingermarks enhanced with conventional methods including cyanoacrylate fuming.
