Ultrasensitive Specific Detection of Anti-influenza A H1N1 Hemagglutinin Monoclonal Antibody Using Silicon Nanowire Field Effect Biosensors.

Rapid and sensitive detection of virus-related antigens and antibodies is crucial for controlling sudden seasonal epidemics and monitoring neutralizing antibody levels after vaccination. However, conventional detection methods still face challenges related to compatibility with rapid, highly sensitive, and compact detection apparatus. In this work, we developed a Si nanowire (SiNW)-based field-effect biosensor by precisely controlling the process conditions to achieve the required electrical properties via complementary metal-oxide-semiconductor (CMOS)-compatible nanofabrication processes.

Efficacy and safety of endovascular coil embolization for unruptured middle cerebral artery aneurysms: middle-term clinical and imaging outcomes with 3 years mean follow-up periods, a 16-year experience.

The anatomical characteristics of middle cerebral artery aneurysms make endovascular treatment difficult. This study evaluated the efficacy and safety of endovascular treatment of unruptured middle cerebral artery aneurysm in preventing rupture. A retrospective review of patients who underwent coil embolization for unruptured middle cerebral artery aneurysm between 2006 and 2022 at Nagoya University Hospital with at least 12 months followed up was conducted.

Three-dimensional spiral-shaping method of microcatheter for paraclinoid aneurysms: assessment using silicone models.

Selecting an appropriate microcatheter tip shape for paraclinoid aneurysms is difficult. Therefore, we devised an original simple and uniform three-dimensional (3D) spiral-shaping method of microcatheter and validated the characteristics and usefulness of this method for coil embolization of paraclinoid aneurysms using patient-specific silicone models. These silicone models were produced based on clinical data from four patients with four paraclinoid aneurysms that underwent endovascular treatment using the 3D spiral-shaping method.

Introduction: Zonisamide is a medication developed in Japan that is effective for motor symptoms and wearing off in Parkinson's disease (PD). Zonisamide has properties that may improve sleep disorders. The aim of this study is to verify the safety and efficacy of zonisamide for sleep disorders and rapid eye movement (REM) sleep behavioral disorders (RBD) using a mobile two-channel electroencephalography /electrooculography recording system in patients with PD.

Single-cell analyses reveal that monocyte gene expression profiles influence HIV-1 reservoir size in acutely treated cohorts.

Elimination of latent HIV-1 is a major goal of AIDS research but the host factors determining the size of these reservoirs are poorly understood. Here, we investigated whether differences in host gene expression modulate the size of the HIV-1 reservoir during suppressive ART. Peripheral blood mononuclear cells (PBMC) from fourteen individuals initiating ART during acute infection who demonstrated effective viral suppression but varying magnitude of total HIV-1 DNA were characterized by single-cell RNA sequencing (scRNA-seq).

Robot-assisted laparoscopic hepatectomy for liver metastasis from clitoral malignant melanoma: a case report.

Introduction: Malignant melanomas occur most commonly in the skin, mucous membranes, or choroid. Clitoral malignant melanomas are extremely rare. Stage IV malignant melanomas have a poor prognosis, and molecularly targeted agents or immune checkpoint inhibitors are recommended.

Transileocolic Portal Vein Embolization Increases Remnant Liver Volume After Major Hepatectomy.

Background/aim: Transileocolic portal vein embolization (TIPE) may reduce the risk of liver failure after massive hepatectomy. However, convincing evidence of its usefulness in this regard is yet to be reported. Therefore, this study aimed to investigate the use of TIPE after massive hepatectomy.

Improvement of Quantification of Myocardial Synthetic ECV with Second-Generation Deep Learning Reconstruction.

Background: The utility of synthetic ECV, which does not require hematocrit values, has been reported; however, high-quality CT images are essential for accurate quantification. Second-generation Deep Learning Reconstruction (DLR) enables low-noise and high-resolution cardiac CT images. The aim of this study is to compare the differences among four reconstruction methods (hybrid iterative reconstruction (HIR), model-based iterative reconstruction (MBIR), DLR, and second-generation DLR) in the quantification of synthetic ECV.

Purpose: To validate the reliability of fibrosis markers as predictors of graft survival in living donor liver transplantation (LDLT) recipients.

Methods: We reviewed data retrospectively, from 163 patients who underwent adult LDLT with preoperative measurements of type IV collagen (CIV), Mac-2 binding protein glycosylation isomer (M2BPGi), and hyaluronic acid (HA). Patients were divided into high and low groups for each biomarker, based on optimal cutoff values, and graft loss within 6 months was evaluated in each group.

Novel protocol for prevention from hepatitis B reactivation following living-donor liver transplantation.

Aim: Reactivation of hepatitis B virus (HBV) after liver transplantation (LT) remains a problem; thus, development of more effective HBV reactivation prophylaxis is desirable. We evaluated the efficacy of a combination of a long-term nucleotide analog (NA), such as entecavir (ETV) or tenofovir alafenamide (TAF), and short-term hepatitis B immunoglobulin (HBIG) in preventing HBV reactivation and compared it with conventional HBV prophylaxis.

Methods: Between February 1999 and August 2023, 135 patients underwent living-donor liver transplantation for liver cirrhosis or acute liver failure caused by HBV infection or received an LT from a hepatitis B core antibody-positive donor.

Spatiotemporal dynamics of fast electron heating in solid-density matter via XFEL.

High-intensity, short-pulse lasers are crucial for generating energetic electrons that produce high-energy-density (HED) states in matter, offering potential applications in igniting dense fusion fuels for fast ignition laser fusion. High-density targets heated by these electrons exhibit spatially non-uniform and highly transient conditions, which have been challenging to characterize due to limitations in diagnostics that provide simultaneous high spatial and temporal resolution. Here, we employ an X-ray Free Electron Laser (XFEL) to achieve spatiotemporally resolved measurements at sub-micron and femtosecond scales on a solid-density copper foil heated by laser-driven fast electrons.
