Over the last several years, foot rot caused by has become the most destructive sweetpotato disease in the southernmost region of Japan. Breeding of cultivars resistant to foot rot is required for effective and low-cost management. Field tests are often used to evaluate resistance of cultivars, but this approach has several limitations, including a long test period of several months and the requirement of field isolation and labor-intensive procedures.

Tau aggregation is a defining feature of neurodegenerative tauopathies, including Alzheimer's disease, corticobasal degeneration, and frontotemporal dementia. This aggregation involves the liquid-liquid phase separation (LLPS) of Tau, followed by its sol-gel phase transition, representing a crucial step in aggregate formation both in vitro and in vivo. However, the precise cofactors influencing Tau phase transition and aggregation under physiological conditions (e.

Objective Crohn's disease (CD) is a chronic inflammatory bowel disease that is associated with malnutrition. Sarcopenia is a malnutrition condition characterized by skeletal muscle loss that impairs the physical function. We investigated the clinical characteristics of patients with CD with sarcopenia and sarcopenic obesity (sarcopenic-o).

Article Synopsis
  • Synucleinopathies, like Parkinson's disease and dementia with Lewy bodies, are caused by the clumping of α-synuclein proteins, leading to nerve cell damage, but the exact mechanism behind this aggregation is still unclear.
  • The study shows that RNA G-quadruplexes form structures that promote α-synuclein aggregation, especially when calcium levels in the cell rise, accelerating the transition from a soluble to a gel-like state of the protein.
  • Using a light-controlled method to induce RNA G-quadruplex formation increases α-synuclein aggregation and neuronal dysfunction, but treating with 5-aminolevulinic acid can prevent this phase separation, reducing protein clumping and related motor

  • This study examined the safety of gastrointestinal endoscopic procedures in patients taking edoxaban, focusing on the incidence of delayed bleeding during and after the operations.
  • Among the 21 patients analyzed, 14% experienced severe delayed bleeding, while no minor bleeding or thromboembolic events were reported.
  • The findings suggest that the risk of delayed bleeding with edoxaban is manageable, but higher blood pressure may raise the risk, warranting further investigation.

α-Synuclein (αS) causes Parkinson's disease due to the structural alteration into amyloid fibrils that form after the interaction with synaptic membranes in neurons. To understand the alternation mechanism, the effect of salt (NaCl) on the interaction of αS with synaptic mimic membrane was characterized at the molecular level because salt triggered the amyloid fibril formation. The membrane-bound conformation (or the initial conformation before fibrillation) showed that NaCl decreased the number of helical structures and Tyr residues interacting with the membrane surface compared to when NaCl was absent, implying an increase in solvent-exposed regions.

We have demonstrated localized surface plasmon (LSP)-enhanced cathodoluminescence (CL) from an atomic layer deposition (ALD)-grown Al2O3/ZnO/Al2O3 heterostructure to develop a bright nanometer-scale light source for an electron beam excitation-assisted (EXA) optical microscope. Three types of metals, Ag, Al, and Au, were compared, and an 181-fold enhancement of CL emission was achieved with Ag nanoparticles (NPs), with the plasmon resonance wavelength close to the emission wavelength energy of ZnO. The enhanced emission is plausibly attributed to LSP/exciton coupling.

Amyloid fibril formation is associated with various amyloidoses, including neurodegenerative diseases such as Alzheimer's and Parkinson's diseases. Despite the numerous studies on the inhibition of amyloid formation, the prevention and treatment of a majority of amyloid-related disorders are still challenging. In this study, we investigated the effects of various plant extracts on amyloid formation of α-synuclein.

Herein, we describe a case of olmesartan-associated sprue-like enteropathy, in which improvement in villous atrophy was confirmed using small bowel capsule endoscopy. The patient was a 69-year-old woman who had persistent watery diarrhea (20 bowel movements/day) for 1 year and experienced a weight loss of 10 kg in the same period. Abdominal computed tomography revealed no abnormalities, and blood test results revealed no inflammatory reactions.

Article Synopsis
  • Neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker that may indicate early acute kidney injury (AKI), but its role in gastrointestinal diseases needed further exploration.
  • In a study of 171 patients with various gastrointestinal conditions, urinary NGAL levels were significantly elevated in those with acute pancreatitis and cholangitis, and also increased in inflammatory bowel diseases and liver diseases.
  • The findings suggest that urinary NGAL may be a better indicator of infection severity rather than just AKI, and higher levels of NGAL are associated with worse hospital outcomes and patient prognosis.

Diversion colitis (DC) is characterized by mucosal inflammation in the defunctioned segment of the colon following a colostomy or ileostomy. The major causes of DC are an increase in the number of aerobic bacteria, a lack of short-chain fatty acids (SCFAs), and immune disorders in the diverted colon. However, its exact pathogenesis remains unknown.

Purpose: Until March 2018, patients with high-risk localized prostate cancer had been administered high-dose-rate brachytherapy (HDR-BT) combined with external beam radiotherapy (EBRT) without additional hormone therapy (HT) at our institution. In this study, we aimed to evaluate long-term outcomes of this treatment.

Materials And Methods: Patients with prostate cancer who received HDR-BT and EBRT between April 1997 and March 2021 and who were followed up for at least 6 months were included in the study.

Lead sulfide colloidal quantum dots (PbS CQDs) show great potential in next-generation photovoltaics. However, their high specific surface area and complex surface crystallography lead to a high surface trap density, which normally requires more than one type of capping ion or ligand to achieve effective surface passivation. In this study, we performed mixed halogen passivation (MHP) during the direct synthesis of semiconducting PbS CQD inks by using different lead halogens.

Background: High-dose-rate brachytherapy (HDR-BT) delivers high-dose radiation to local lesions within a short treatment period. There are no reports of salvage transurethral HDR-BT for biochemical recurrence (BCR) after radical prostatectomy. Thus, we aimed to evaluate the usefulness of salvage transurethral HDR-BT with external beam radiation therapy (EBRT) for anastomotic prostate cancer recurrence.
