Fabry disease (FD) is an inherited lysosomal storage disease caused by deficiency of α-galactosidase A (α-Gal A), an enzyme that hydrolyzes glycosphingolipids in lysosome. Accumulation of glycosphingolipids, mainly globotriaosylceramide (Gb3) in tissues, induces cellular dysfunction leading to multi-organ disorder. Gene therapy is a promising strategy that can overcome these problems, and virus vectors such as adeno-associated virus (AAV) have been used for study on gene therapy.

In contrast to the stereoselectivity obtained with conventional nonfluorous ligands, using bisoxazoline bidentate ligands featuring two fluorous tags in adjacent positions on the aromatic ring yielded a reversed stereoselectivity. The stereoselectivity also reversed when the fluorous tags were replaced with alkyl chains of equivalent length, albeit to a considerably lesser degree, highlighting the effect of the fluorous tags.

Several second-line treatments with molecular target agents have shown survival benefits. However, the significance of post-progression survival (PPS) in extending OS in patients with HCC given such treatments remains uncertain.

Post-progression survival (PPS) has been reported to be a great contributor in the treatment with tyrosine kinase inhibitors for unresectable HCC. This study aimed to clarify the significance of progression-free survival (PFS) or PPS of Atez/Bev treatment for HCC.

The symptoms of FD occur as a result of the accumulation of globotriaosylceramide (Gb3), comprising a substrate of α-Gal A, in the organs. Adeno-associated virus (AAV)-mediated gene therapy is a promising treatment for FD.

HCV eradication improves these complications in some patients, but the long-term effects of HCV eradication on these complications remain unclear, especially in patients treated with direct acting antivirals (DAAs). The aim was to evaluate long term changes in thrombocytopenia and leucopenia after HCV eradication with DAAs.

Background: Parkinson's disease (PD) adversely affects the quality of life (QoL) of not only patients but also their caregivers.
Objective: To determine the factors that most impact the QoL of family caregivers of patients with PD in a large Japanese population using data from the Japanese Quality-of-Life Survey of Parkinson's Disease (JAQPAD) study.
Methods: Questionnaires, including the Parkinson's Disease Questionnaire-Carer (PDQ-Carer), were distributed to patients and their caregivers.
The influenza A(H1N1)pdm09 virus that emerged in 2009 causes seasonal epidemic worldwide. The virus acquired several amino acid substitutions that were responsible for antigenic drift until the 2018-2019 influenza season. Viruses possessing mutations in the NA and PA proteins that cause reduced susceptibility to NA inhibitors and baloxavir marboxil, respectively, have been detected after antiviral treatment, albeit infrequently.

Interventional therapies such as radiofrequency ablation (RFA) or transcatheter arterial embolization (TAE) have been shown to limit the development of sHCC through mechanisms involving hypoxia-induced epithelial-mesenchymal transition. This report describes an 83-year-old man who developed sHCC 2 years after RFA treatment for HCC and experienced sHCC rupture.

Objectives: We sought to clarify the molecular pathogenesis of a patient with early-onset multiple allergic diseases, a high serum IgE level, hypereosinophilia, treatment-resistant severe atopic dermatitis with increased dermal collagen fiber deposition, and eosinophilic gastrointestinal disorder with numerous polypoid nodules.
Background/aim: Lenvatinib is a tyrosine kinase inhibitor (TKI) more effective against hepatocellular carcinoma (HCC) than sorafenib, making lenvatinib a first-line treatment option for patients with unresectable HCC. In patients treated with sorafenib, post-progression survival (PPS) rather than progression-free survival (PFS) is essential for overall survival (OS). However, the importance of PPS for OS in patients treated with lenvatinib is uncertain, and optimal treatment after lenvatinib failure has not yet been established.

Antimitochondrial antibody M2 (AMA-M2) is known as one of the serologic hallmarks of primary biliary cholangitis (PBC). There have been several reports on the association between AMA-M2 and various types of inflammatory myopathy, including cardiomyopathy.

Although eradication of HCV is expected to reduce this risk, the risk in patients with a history of HCC may be high after treatment with direct-acting antivirals (DAAs).
Aim: To determine the risk factors for HCC recurrence in patients with HCV and a history of HCC.
Brown adipose tissue (BAT) has a role in maintaining systemic metabolic health in rodents and humans. Here, we show that metabolic stress induces BAT to produce coagulation factors, which then-together with molecules derived from the circulation-promote BAT dysfunction and systemic glucose intolerance. When mice were fed a high-fat diet (HFD), the levels of tissue factor, coagulation Factor VII (FVII), activated coagulation Factor X (FXa), and protease-activated receptor 1 (PAR1) expression increased significantly in BAT.

So far, detailed studies on the efficacy of unilateral STN-DBS for motor symptoms have been reported, but few studies have been conducted on unilateral GPi-DBS.
Materials And Methods: Seventeen patients with Parkinson's disease (PwPD) who underwent unilateral GPi-DBS were selected.
We report a rare case of hereditary breast and ovarian cancer syndrome (HBOC) with pathogenic variants in both and . The patient was a 78-year-old woman who visited the hospital after noticing a lump in her left breast 6 months before, which gradually increased in size. According to her family history, her maternal aunt developed breast cancer in her 40s.
