Fabrication of Three-Dimensionally Deformable Metal Structures Using Precision Electroforming.

It is difficult to fabricate three-dimensional structures using semiconductor-process technology, because it is based on two-dimensional layered structure fabrication and the etching of thin films. In this study, we fabricated metal structures that can be dynamically deformed from two-dimensional to three-dimensional shapes by combining patterning using photolithography with electroforming technology. First, a resist structure was formed on a Cu substrate.

Thermal tissue damage caused by new endoscope model due to light absorption.

Background And Aim: Bright endoscopic light sources improve the visibility of the intestinal mucosa. A newly launched endoscopic system developed by Olympus Corporation (Tokyo, Japan) in 2020 required modification to prevent heat-induced tissue damage, which reportedly occurs during magnifying chromoendoscopy. We investigated the mechanism of this phenomenon by evaluating the rise in temperature of stained and unstained porcine mucosa using the new and previous endoscopic systems.

Clinical impact of central nervous system-directed therapies on intravascular large B-cell lymphoma: A single institution's experience.

Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of B-cell lymphoma characterized by aggressive disease progression with a high incidence of central nervous system (CNS) involvement. We retrospectively analyzed 16 patients with de novo IVLBCL treated at our hospital between 2004 and 2018 with either standard therapy plus CNS-directed therapy or standard therapy alone. CNS-directed therapy was associated with a significantly better 2-year CNS-free survival (100% vs.

The cell surface hyaluronidase TMEM2 plays an essential role in mouse neural crest cell development and survival.

Hyaluronan (HA) is a major extracellular matrix component whose tissue levels are dynamically regulated during embryonic development. Although the synthesis of HA has been shown to exert a substantial influence on embryonic morphogenesis, the functional importance of the catabolic aspect of HA turnover is poorly understood. Here, we demonstrate that the transmembrane hyaluronidase TMEM2 plays an essential role in neural crest development and the morphogenesis of neural crest derivatives, as evidenced by the presence of severe craniofacial abnormalities in Wnt1-Cre-mediated Tmem2 knockout (Tmem2CKO) mice.

Dynamic analysis of the ulnar nerve and cubital tunnel morphology using ultrasonography: a cadaveric study.

Background: The causes of ulnar neuropathy at the elbow are unclear. The authors hypothesized that the humeral trochlea protrudes into the cubital tunnel during elbow flexion and causes a dynamic morphologic change of the ulnar nerve in the cubital tunnel.

Methods: An ultrasonic probe was fixed to the ulnar shafts of 10 fresh cadavers with an external fixator, and dynamic morphology of the cubital tunnel and ulnar nerve was observed.

Impact of corticosteroid use on the clinical response and prognosis in patients with cardiac sarcoidosis who underwent an upgrade to cardiac resynchronization therapy.

Antibiotic-dependent effect of probiotics in patients with non-small cell lung cancer treated with PD-1 checkpoint blockade.

Background: We previously validated in European patients with NSCLC treated with programmed death-1 (PD-1) checkpoint inhibitors the cumulative detrimental effect of concomitant medications.

Materials And Methods: We evaluated the prognostic ability of a "drug score" computed on the basis of baseline corticosteroids, proton pump inhibitors, and antibiotics, in an independent cohort of Japanese patients with advanced NSCLC treated with PD-1 monotherapy. Subsequently, we assessed the impact of baseline probiotics on the score's diagnostic ability and their interaction with antibiotics in influencing survival.

Modeling Axonal Degeneration Using Motor Nerve Organoids.

Degeneration of axons is characteristic of many devastating diseases including amyotrophic lateral sclerosis (ALS). However, lack of an in vitro neuronal culture system that mimics damages on nerves and axonal tracts hampered development of effective treatments. Here, we describe a method to model degeneration of motor neuron axons using motor nerve organoids that are formed with human induced pluripotent stem cells.

Estrogen induces the expression of EBV lytic protein ZEBRA, a marker of poor prognosis in nasopharyngeal carcinoma.

Several epidemiological studies have suggested that Epstein-Barr virus (EBV) lytic infection is essential for the development of nasopharyngeal carcinoma (NPC), as the elevation of antibody titers against EBV lytic proteins is a common feature of NPC. Although ZEBRA protein is a key trigger for the initiation of lytic infection, whether its expression affects the prognosis and pathogenesis of NPC remains unclear. In this study, 64 NPC biopsy specimens were analyzed using immunohistochemistry.
