Detection of ultrafast electron energization by whistler-mode chorus waves in the magnetosphere of Earth.

Electromagnetic whistler-mode chorus waves are a key driver of variations in energetic electron fluxes in the Earth's magnetosphere through the wave-particle interaction. Traditionally understood as a diffusive process, these interactions account for long-term electron flux variations (> several minutes). However, theories suggest that chorus waves can also cause rapid (< 1 s) electron acceleration and significant flux variations within less than a second through a nonlinear wave-particle interaction.

Evaluation of the Efficacy and Accuracy of Super-Flexible Three-Dimensional Heart Models of Congenital Heart Disease Made via Stereolithography Printing and Vacuum Casting: A Multicenter Clinical Trial.

Three-dimensional (3D) printing is an advanced technology for accurately understanding anatomy and supporting the successful surgical management of complex congenital heart disease (CHD). We aimed to evaluate whether our super-flexible 3D heart models could facilitate preoperative decision-making and surgical simulation for complex CHD. The super-flexible heart models were fabricated by stereolithography 3D printing of the internal and external contours of the heart from cardiac computed tomography (CT) data, followed by vacuum casting with a polyurethane material similar in elasticity to a child's heart.

Evaluation of the effects of fenestration in Fontan circulation using a lumped parameter model.

Fenestration has been reported to enhance Fontan hemodynamics in several cases of Fontan circulation. However, the indication criteria for fenestration remain under discussion. To assess the effectiveness of fenestration in Fontan circulation, we conducted a theoretical analysis using a computational model of the fenestrated Fontan circulation.

A cryptic promoter in the exon of HKR1 drives expression of a truncated form of Hkr1 in Saccharomyces cerevisiae.

Hansenula mrakii killer toxin resistant gene 1 (HKR1) is an intronless, single-exon gene that encodes Hkr1, the signaling mucin of the budding yeast Saccharomyces cerevisiae. HKR1 overexpression confers S. cerevisiae cells with resistance to the HM-1 killer toxin produced by the killer yeast Hansenula mrakii (currently known as Cyberlindnera mrakii).

Effects of systemic ventricular assist in failing Fontan patients: a theoretical analysis using a computational model.

Mechanical circulatory support is a potential treatment for failing Fontan patients. In this study, we performed a theoretical analysis using a computational model to clarify the effects of systemic ventricular assist device (VAD) in failing Fontan patients. Cardiac chambers and vascular systems were described using the time-varying elastance model and modified Windkessel model, respectively.

Precuneal hyperperfusion in patients with attention-deficit/hyperactivity disorder-comorbid nociplastic pain.

Introduction: Nociplastic pain (NP), a third category of chronic pain, offers a framework for elucidating its pathophysiology and treatment strategies. One of the characteristics of NP is comorbidity of symptoms other than pain, such as psychological and cognitive problems; therefore, these can be clues to understanding NP. Recently, we reported several cases with comorbid symptoms of attention-deficit/hyperactivity disorder (ADHD).

Association Between Physical Activity and Performance in Skill Learning Among Older Adults Based on Cognitive Function.

Background/objectives: Most older adults experience cognitive and physical functioning problems; however, they require the ability to learn skills in response to age-related or social environmental changes for independent living. This study aimed to clarify the associations between age-related physical activity and performance in skill learning tasks based on cognitive function.

Methods: Fifty-eight adults participated in this study and were divided into two groups: the control group (aged under 65 years) and older adult group (aged over 65).

Expression of c-jun/c-fos mRNA Indicates Persistent Myocardial Stretch During Asphyxia-Induced Cardiac Arrest.

Right ventricular dysfunction is a key clinical issue for the viability of donation-after-circulatory-death (DCD) heart transplantation. DCD hearts with volume overload have the potential to exhibit aggravated right ventricular dysfunction following heart transplantation. The c-jun/c-fos mRNAs are genes that immediately respond to myocardial cell stretch.

Development of a FUT8 Inhibitor with Cellular Inhibitory Properties.

Core fucosylation is catalyzed by α-1,6-fucosyltransferase (FUT8), which fucosylates the innermost GlcNAc of N-glycans. Given the association of FUT8 with various diseases, including cancer, selective FUT8 inhibitors applicable to in vivo or cell-based systems are highly sought-after. Herein, we report the discovery of a compound that selectively inhibits FUT8 in cell-based assays.

Long-Term Outcome of Eltrombopag With First-Line Immunosuppressive Therapy for Newly Diagnosed Severe Aplastic Anemia.

Background: To investigate whether the addition of eltrombopag (EPAG) to rabbit anti-thymocyte globulin (ATG)-based immunosuppressive therapy (IST) for newly diagnosed severe aplastic anemia (SAA) improves outcomes and affects the cumulative incidence of clonal evolution (CE), we conducted a multicenter retrospective analysis.

Methods: Data were collected from 101 patients, aged 15 - 65 years, undergoing initial IST.

Results: No significant imbalance in age, sex, or severity was observed between the EPAG (n = 20) and non-EPAG (n = 81) groups.

Case Report: Methylphenidate and venlafaxine improved abdominal nociplastic pain in an adult patient with attention deficit hyperactivity disorder, autism spectrum disorder, and comorbid major depression.

Introduction: Nociplastic pain (NP), classified as a third type of pain alongside nociceptive and neuropathic pain, is chronic pain arising from the amplification of nociceptive stimuli through central sensitization, despite the absence of tissue damage, sensory nerve damage, or disease. An important clinical feature of NP is that it is not only associated with pain but also with sensory hypersensitivity to sound and light and cognitive dysfunction, including mood and attention disorders. Recent studies have suggested that depression and developmental disorders, such as attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), coexist with NP at high frequency.

Validity and Reliability of OpenPose-Based Motion Analysis in Measuring Knee Valgus during Drop Vertical Jump Test.

OpenPose-based motion analysis (OpenPose-MA), utilizing deep learning methods, has emerged as a compelling technique for estimating human motion. It addresses the drawbacks associated with conventional three-dimensional motion analysis (3D-MA) and human visual detection-based motion analysis (Human-MA), including costly equipment, time-consuming analysis, and restricted experimental settings. This study aims to assess the precision of OpenPose-MA in comparison to Human-MA, using 3D-MA as the reference standard.

Development of Antimicrobial Surfaces Using Diamond-like Carbon or Diamond-like Carbon-Based Coatings.

The medical device market is a high-growth sector expected to sustain an annual growth rate of over 5%, even in developed countries. Daily, numerous patients have medical devices implanted or inserted within their bodies. While medical devices have significantly improved patient outcomes, as foreign objects, their wider use can lead to an increase in device-related infections, thereby imposing a burden on healthcare systems.

The BDNF-ERK/MAPK axis reduces phosphatase and actin regulator1, 2 and 3 (PHACTR1, 2 and 3) mRNA expressions in cortical neurons.

Actin rearrangement and phosphorylation-dephosphorylation in the nervous system contribute to plastic alteration of neuronal structure and function. Phosphatase and actin regulator (PHACTR) family members are actin- and protein phosphatase 1 (PP1)-binding proteins. Because some family members act as regulators of neuronal morphology, studying the regulatory mechanisms of PHACTR is valuable for understanding the basis of neuronal circuit formation.

Collagen patches releasing phosphatidylserine liposomes guide M1-to-M2 macrophage polarization and accelerate simultaneous bone and muscle healing.

Bilateral communication between bones and muscles is essential for healing composite bone-muscle injuries from orthopedic surgeries and trauma. However, these injuries are often characterized by exaggerated inflammation, which can disrupt bone-muscle crosstalk, thereby seriously delaying the healing of either tissue. Existing approaches are largely effective at healing single tissues.

Abductor hallucis muscle activity during short foot exercise in combination with static and dynamic functional tasks.
