Indoxyl Sulfate-Induced Macrophage Toxicity and Therapeutic Strategies in Uremic Atherosclerosis.

Cardiovascular disease (CVD) frequently occurs in patients with chronic kidney disease (CKD), particularly those undergoing dialysis. The mechanisms behind this may be related to traditional risk factors and CKD-specific factors that accelerate atherosclerosis and vascular calcification in CKD patients. The accumulation of uremic toxins is a significant factor in CKD-related systemic disorders.

Effectiveness of S-Shaping of the Tip of the FUBUKI Guiding Catheter to Match the Shape of the Cervical Internal Carotid Artery in Anterior Circulation Cerebral Aneurysm Embolization.

Objective: During cerebral aneurysm embolization of the anterior circulation, the guiding catheter (GC) should be placed as distally as possible in the cervical internal carotid artery (ICA) to secure the maneuverability of the microcatheter and distal access catheter. However, if the shape of the tip of the GC does not appropriately match the course of the ICA, blood stasis might occur. We investigated whether shaping the tip of the GC into an S-shape would allow more stable catheterization to the distal ICA than the conventional GC with an angled tip.

A diagnostic approach of various urethral diseases using multimodal imaging findings: comprehensive overview.

In clinical practice, urethral diseases are not as frequent as conditions affecting other components of the urinary system. Radiological imaging tests, such as retrograde urethrography, CT, MRI, and PET/CT, along with patient history, are crucial for accurately assessing relatively rare urethral lesions. This article aimed to provide a comprehensive overview of urethral lesions, from traumatic changes to neoplasms, and discuss the multimodal imaging findings of various urethral lesions that radiologists should know.

Impact of Controlling Nutritional Status Score on Comprehensive Clinical Outcomes in Patients With Chronic Limb-Threatening Ischemia in a Local Area of Super-Aged Society.

Purpose: This study aimed to evaluate the relationship between nutritional status and hospital outcomes in patients with chronic limb-threatening ischemia (CLTI) in a local area of contemporary super-aged society of Japan.

Materials And Methods: We analyzed 131 consecutive patients with 179 lower limb diseases admitted to our hospital for the treatment of CLTI between April 2018 and March 2023. These 131 patients were divided into 3 groups according to hospital outcomes: home discharge (HD), out-of-home discharge (OD), and in-hospital death (ID).

Dysregulation of SNX1-retromer axis in pharmacogenetic models of Parkinson's disease.

Since the identification of vacuolar protein sorting (VPS) 35, as a causative molecule for familial Parkinson's disease (PD), retromer-mediated endosomal machinery has been a rising factor in the pathogenesis of the disease. The retromer complex cooperates with sorting nexin (SNX) dimer and DNAJC13, another causal molecule in PD, to transport cargoes from endosomes to the trans-Golgi network, and is also involved in mitochondrial dynamics and autophagy. Retromer dysfunction may induce neuronal death leading to PD via several biological cascades, including misfolded, insoluble α-synuclein (aS) accumulation and mitochondrial dysfunction; however, the detailed mechanisms remain poorly understood.

Minimal Involvement of P-gp and BCRP in Oral Absorption of Ensitrelvir, An Oral SARS-CoV-2 3C-like Protease Inhibitor, in a Non-Clinical Investigation.

P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) are important transporters causing drug-drug interaction (DDI). Here, we investigated the involvement of P-gp and BCRP in the oral absorption of ensitrelvir in non-clinical studies and estimated the DDI risk mediated by P-gp and BCRP inhibition in humans. Although ensitrelvir is an in vitro P-gp and BCRP substrate, it demonstrated high bioavailability in rats and monkeys after oral administration.

Water temperature effects on embryonic development and GnRH-like expression in kisslip cuttlefish (Sepia lycidas) hinting the potential role of GnRH-like peptide.

Gonadotropin-releasing hormone (GnRH)-like peptides are multifunctional neuropeptides involved in cardiac control, early ontogenesis, and reproduction in cephalopods. However, the precise role of GnRH-like peptides in embryonic development and juvenile growth in cephalopods remains unknown. In this study, we showed that GnRH-like peptides are involved in the embryonic development of kisslip cuttlefish (Sepia lycidas).

Colorectal adenoma detection rate using texture and color enhancement imaging versus white light imaging with chromoendoscopy: a propensity score matching study.

Background And Aim: Few studies have evaluated the adenoma detection rate (ADR) of colonoscopy with texture and color enhancement imaging (TXI), a novel image-enhancing technology. This study compares the detection of colorectal polyps using TXI to that using white light imaging (WLI).

Methods: This single-center retrospective study used propensity-matched scoring based on the patients' baseline characteristics (age, sex, indication, bowel preparation, endoscopist, colonoscope type, and withdrawal time) to compare the results of patients who underwent chromoendoscopy using WLI or TXI at the Toyoshima Endoscopy Clinic.

Changes in skin discoloration according to clofazimine dosage in nontuberculous mycobacterial pulmonary disease.

Although clofazimine is currently one of the standard regimens for Mycobacterium abscessus, it frequently causes skin discoloration, posing esthetic concerns for patients. We studied thirteen Asian patients with pulmonary nontuberculous mycobacterial disease treated with clofazimine at the NHO Kinki Chuo Chest Medical Center. In three patients (two women and one man) whose dosing regimens were altered owing to skin discoloration, we continuously measured luminance (L*), red-green (a*), and yellow-blue (b*) values (using a colorimeter) in both sun-exposed and sun-unexposed skin areas at each visit.

Purpose: Recently, there have been a few reports regarding the usefulness of a novel saline injection technique using a spiral flow-generating tube. The purpose of this study was to evaluate whether simultaneous saline injection using a spiral flow-generating tube was able to improve hepatic contrast enhancement and lesion conspicuity of metastatic liver tumors.

Methods: We randomized a total of 411 patients with various liver diseases including metastases by total body weight (A, n = 204) and contrast dilution protocol (B, n = 207).

Melatonin: Unveiling the functions and implications in ocular health.

Melatonin, a versatile hormone produced by the pineal gland, has garnered considerable scientific interest due to its diverse functions. In the eye, melatonin regulates a variety of key processes like inhibiting angiogenesis by reducing vascular endothelial growth factor levels and protecting the blood-retinal barrier (BRB) integrity by enhancing tight junction proteins and pericyte coverage. Melatonin also maintains cell health by modulating autophagy via the Sirt1/mTOR pathways, reduces inflammation, promotes antioxidant enzyme activity, and regulates intraocular pressure fluctuations.

Comprehensive gene expression analysis using RNA sequencing between male and female patients with idiopathic carpal tunnel syndrome.

Idiopathic carpal tunnel syndrome is the most common entrapment neuropathy in hand surgery, and it is characterized by Noninflammatory fibrosis of subsynovial connective tissues. The prevalence and incidence differ between male and female individuals, and the mechanism underlying this difference remains largely unclear. In the present study, we collected subsynovial connective tissues from six male and six female patients diagnosed with idiopathic carpal tunnel syndrome during surgery.

A robust system of hybridogenesis that increases genetic variability and promotes evolutionary succession in greenlings (Teleostei: Hexagrammidae, genus Hexagrammos): Regeneration of a new hemiclonal lineage.

Unisexual hybrids that reproduce either clonally or hemiclonally are considered to be evolutionarily short-lived as they lack the ability to reduce deleterious mutations and increase genetic diversity. In the greenling (Teleostei: Hexagrammidae, genus Hexagrammos), unisexual hybrids that produce haploid eggs containing only the H. octogrammus (maternal species) genome generate hemiclonal offspring by fertilization with haploid sperm of H.

Principles of amyloplast replication in the ovule integuments of Arabidopsis thaliana.

Plastids in vascular plants have various differentiated forms, among which amyloplasts are crucial for starch storage and plant productivity. Despite the vast knowledge of the binary-fission mode of chloroplast division, our understanding of the replication of non-photosynthetic plastids, including amyloplasts, remains limited. Recent studies have suggested the involvement of stromules (stroma-filled tubules) in plastid replication when the division apparatus is faulty.

Redefining awn development in rice through the breeding history of Japanese awn reduction.

The study challenges the conventional understanding of awn loss as a domestication syndrome, showing instead that many awned varieties continued to be widely grown in Japan until the early twentieth century and that selection for awn reduction was active at that time, demonstrating that awn loss is not a domestication syndrome but "a trait that emerged during crop improvement". Although selection for awnless mutants was carried out independently using different types of awned cultivars in the early twentieth century in Japan, awn loss was caused by the mutation in This suggests that a single mutant haplotype of was conserved in the genomes of different cultivars and subsequently selected within each line to meet the demand for awnless varieties. The study also conducts phylogenetic analyses of in 48 grass plants, revealing its unique involvement in awn formation in rice while potentially playing a different role in the domestication of other grass plants.

Biallelic loss-of-function variants of EZH1 cause a novel developmental disorder with central precocious puberty.

Pathogenic variants of polycomb repressive complex-2 (PRC2) subunits are associated with overgrowth syndromes and neurological diseases. EZH2 is a major component of PRC2 and mediates the methylation of H3K27 trimethylation (H3K27me3). Germline variants of EZH2 have been identified as a cause of Weaver syndrome (WS), an overgrowth/intellectual disability (OGID) syndrome characterized by overgrowth, macrocephaly, accelerated bone age, intellectual disability (ID), and characteristic facial features.
