Chiroptically Active Host-Guest Composites Using a Terpene-Based Micellar Capsule.

For the design of a new chiroptically active host-guest system, a bent amphiphilic compound was synthesized using cyclic monoterpenes as key biorelated chiral frameworks. In water, the bent amphiphiles form a terpene-based micellar capsule with a core diameter of ∼2 nm in a spontaneous and quantitative fashion. The resultant chiral capsule shows wide-ranging uptake abilities toward achiral fluorescent dyes in water.

Single-Cell Analysis of Elemental Contents by Laser Ablation-Inductively Coupled Plasma Mass Spectrometry.

Elemental analysis at the single-cell level is an emerging technique in the field of inductively coupled plasma mass spectrometry (ICP-MS). In comparison to the analysis of cell suspensions by fast time-resolved analysis, single-cell sampling by laser ablation (LA) allows the discriminatory analysis of single cells according to their size and morphology. In this study, we evaluated the changes in elemental contents in a single cell through differentiation of rat adrenal pheochromocytoma into neuron-like cells by LA-ICP-MS.

Coverage of lateral soft tissue defects with sartorius muscle flap after distal femoral replacement for malignant bone tumors.

Introduction: To prevent infection after limb-sparing surgery for primary malignant bone tumors, it is important to cover the megaprosthesis with muscle tissue that has sufficient blood flow. Coverage with a lateral gastrocnemius flap has been reported in cases of distal femoral replacement in which the vastus lateralis and vastus intermedius muscles have been resected; however, the risk of peroneal nerve palsy is reportedly high because the muscle flap passes near the peroneal head. This study was performed to examine the postoperative outcomes of patients with primary malignant bone tumors of the distal femur who underwent wide resection (including the vastus lateralis and vastus intermedius muscles) followed by reconstruction with a megaprosthesis and coverage of the lateral side of the prosthesis with a sartorius muscle flap.

Clinical, Pathological, and Genetic Characteristics of Patients with Digenic Alport Syndrome.

Key Points: Patients with both and variants exhibited poor renal prognosis compared with those with autosomal dominant Alport syndrome. The proportion of patients with digenic Alport syndrome was 1.7% among all patients with Alport syndrome.

Genotype and X-chromosome inactivation are associated with disease severity in females with X-linked Alport syndrome.

Background And Hypothesis: Male patients with X-linked Alport syndrome (XLAS) generally develop end-stage kidney disease in early or middle adulthood and show distinct genotype-phenotype correlations. Female patients, however, show various phenotypes ranging from asymptomatic to severe with no genotype-phenotype correlations. However, the factors affecting the severity of XLAS in female patients are unclear.

Emergency Surgery for Adnexal Torsion in Late Preterm Pregnancy Causing Term Vaginal Delivery: A Case Report and Literature Review.

Adnexal cyst torsion in late preterm pregnancies is rare, but it frequently causes secondary uterine contractions. Thus, deciding on performing a simultaneous cesarean section due to the potential for early postoperative labor onset is crucial despite no obstetric indications. Here, we report a case of adnexal torsion at 34 weeks of gestation treated with emergency surgery, followed by a full-term vaginal delivery, along with a literature review.

Efficacy and Safety of Biologics in Polymyalgia Rheumatica: A Retrospective Study.

Introduction: The study aimed to determine the efficacy and safety of biological disease-modifying antirheumatic drugs (bDMARDs) in the treatment of polymyalgia rheumatica (PMR) complicated by rheumatoid arthritis (RA).

Methods: Patients with PMR which could be classified as RA and who were treated with bDMARDs were included in the analysis. The primary endpoint was the clinical Polymyalgia Rheumatica Activity Score (Clin-PMR-AS) after 26 weeks of treatment, and the secondary endpoint was adverse events during the observation period.

Objective: To assess safety of baricitinib in Japanese patients with rheumatoid arthritis in real-world clinical practice.

Methods: This all-case post-marketing surveillance study included patients initiating baricitinib for rheumatoid arthritis from September 2017 to April 2019. Treatment duration was recorded.

Growth of metal nanowire forests controlled through stress fields induced by grain gradients.

Pure metal nanowires (NWs) are one-dimensional nanomaterials with distinctive properties for various applications. Nevertheless, mass-growth forests have not been developed because of vapor pressure limitations, chemical reduction problems, or both. We succeeded in the mass growth of aluminum (Al) NW forests at desired locations by controlling atomic diffusion within the solid film.

Optimizing thrombectomy in medium vessel occlusion: Focus on vessel diameter.

Objectives: Mechanical thrombectomy for medium vessel occlusion (MeVO) is a challenging field with limited results. In this study, we aimed at evaluating the efficacy and safety of a procedural strategy beginning with occluded vessel diameter measurement and matched aspiration catheter selection.

Materials And Methods: We retrospectively analyzed all sequentially treated patients by mechanical thrombectomy at two comprehensive stroke centers between May 2020 and April 2023, focusing on the occluded vessel diameter.

Regulation of the expression of MHETase and TPA degradation genes involved in the degradation of PET in Ideonella sakaiensis.

Ideonella sakaiensis is a bacterium that can degrade and consume polyethylene terephthalate (PET), a plastic material that was previously considered non-biodegradable. The degradation of PET requires two enzymes, namely poly (ethylene terephthalate) hydrolase (PETase) and mono (2-hydroxyethyl) terephthalate hydrolase (MHETase), which break down PET into terephthalate (TPA) and ethylene glycol (EG), which serve as carbon sources for the bacterium. Previous studies have focused on the enzymatic properties, structure, and mechanism of action of PETase and MHETase.

A Japanese Case of Food Protein-induced Enterocolitis Syndrome Caused by Multiple Seafoods.

Food protein-induced enterocolitis syndrome (FPIES) caused by fish and others is prevalent in the Mediterranean regions but is less frequently reported in Japan. This case report describes a 3-year-old Japanese girl who developed FPIES triggered by multiple seafoods, including swordfish, cod, and squid. The diagnosis was confirmed through oral food challenge tests (OFC), which led to repeated vomiting and an increase in thymus and activation-regulated chemokine (TARC) levels.

Obesity impairs ciliary function and mucociliary clearance in the murine airway epithelium.

Obesity is a risk factor for increased morbidity and mortality in viral respiratory infection. Mucociliary clearance (MCC) in the airway is the primary host defense against viral infections. However, the impact of obesity on MCC is unclear, prompting this study.

The relationship between DASC-8 categories and the effectiveness of education on insulin self-injection techniques in elderly patients with diabetes.

Aim: Education on insulin self-injection techniques is important for good glycemic control, but its effectiveness in some elderly patients is limited due to loss of cognitive function and impaired activities of daily living. We hypothesized that classification using the Dementia Assessment Sheet for Community-based Integrated Care System 8-items (DASC-8) would help identify elderly patients with diabetes who effectively learn self-injection techniques.

Methods: Diabetes patients aged ≥ 65 years who used a self-injection insulin pen were administered the DASC-8 and a questionnaire to evaluate insulin self-injection techniques, and then received technical education.

Diacylglycerol O-acyltransferase 1 inhibitor increases plasma alanine aminotransferase and aspartate aminotransferase activities via a shedding of the intestinal villi and an increase in intestinal permeability in rats.

Diacylglycerol O-acyltransferase 1 (DGAT1) is a key enzyme for fat absorption step in the enterocytes. We previously reported that DGAT1 inhibition increased plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities in corn oil-loaded rats via protein kinase C (PKC) activation. In the present study, we investigated the mechanism with respect to the morphology and permeability of the small intestine, focusing on PKC function, and found that shortening of the intestinal villi and a decrease in the number of tdT-mediated dUTP-biotin nick-end labeling-positive cells in the tips of the villi were observed in the jejunum of DGAT1 inhibitor-treated rats loaded with corn oil.

Establishment of the improved colonization of Escherichia coli laboratory strain in the intestine mediated by single gene deletion.

In light of the emerging importance of the gut microbiome in human health, there is a need to improve the colonization efficiency of therapeutic bacteria called probiotics. Despite their recognized potential, artificially administered bacteria exhibit poor colonization in the intestine, limiting their therapeutic efficacy. Addressing this challenge requires innovative strategies; however, reported examples are limited.

In steroid-resistant nephrotic syndrome that meets the strict definition, monogenic variants are less common than expected.

Background: In patients with steroid-resistant nephrotic syndrome (SRNS), the presence of monogenic variants influences therapeutic strategies. Large cohort studies reported the detection of monogenic variants in approximately 30% of patients with SRNS. However, these cohorts included many patients, such as those with symptomatic proteinuria, who did not meet the strict diagnostic criteria for pediatric nephrotic syndrome (NS).
