The "duckweed-microbes co-cultivation method" is a microbial isolation technique that effectively recovers diverse microbes, including rarely cultivated bacterial phyla, from environmental samples. In this method, aseptic duckweed and microbes collected from an environmental sample are co-cultivated for several days, and duckweed-associated microbes are then isolated from its roots using a conventional agar plate-based cultivation method. We herein propose several improvements to the method in order to specifically obtain members of the rarely cultivated bacterial phylum, Verrucomicrobiota.

Common variable immunodeficiency (CVID) is a primary B cell immunodeficiency disorder. Symptoms do not develop immediately after birth, and patients are often diagnosed in childhood and adulthood. These patients often develop autoimmune diseases and malignant tumors.

It maintains redox homeostasis through a variety of enzymatic and non-enzymatic antioxidant molecules. In contrast to mammals, Euglena possesses nonselenocysteine glutathione peroxidase homologues that regulate its intracellular pools of reactive oxygen species.

There is a strong need to predict bleeding and thrombosis risks before ITP treatment to optimize therapy and appropriately manage these complications. We performed a retrospective cohort study of 120 patients with primary ITP to identify a biomarker to predict bleeding and thrombosis.

An SVV test smartphone app was developed to easily perform assessments in outpatient facilities.
Objective: This study aimed to verify whether the SVV test smartphone app with commercially available virtual reality goggles can be used in a clinical setting.
Background: Isatuximab, an anti-CD38 antibody, has been widely used in treatments for patients with relapsed/refractory multiple myeloma (MM). Despite its high efficacy, not all patients achieve a lasting therapeutic response with isatuximab.
Objective: We tried to identify biomarkers to predict the effectiveness of isatuximab by focusing on the host's immune status before treatment.
Background: The Scenario Test is recognised for its effectiveness in assessing the interactive aspects of functional communication in people with post-stroke aphasia (PWA).
Aims: To develop a Japanese version of the Scenario Test (Scenario Test-JP) and assess its reliability and validity.
Methods & Procedures: Among 66 participants, we selected 61 individuals: 34 PWA and 27 healthy controls (HCs).
Objective: Airway surgery is performed for COVID-19 patients who require long-term tracheal intubation and mechanical ventilation. Tracheostomy sometimes causes postoperative complications represented by bleeding at a relatively high rate in COVID-19 patients. As an alternative surgical procedure to tracheostomy, cricotracheostomy may reduce these complications, but few studies have examined its safety.

The Japanese Society of Hematology conducted a prospective observational study in newly diagnosed PCN patients between 2016 and 2021. The analysis focused on 1385 patients diagnosed with symptomatic PCN between 2016 and 2018.

Two patients presented with progression or recurrence of B-cell chronic lymphocytic leukemia (B-CLL)/small lymphocytic lymphoma (SLL), two with diffuse large B-cell lymphoma (DLBCL) of non-germinal center B-like phenotype, and the remaining one with composite angioimmunoblastic T-cell lymphoma and Epstein-Barr virus-positive DLBCL.

However, the potential graft-versus-solid-tumor (GVT) effect of this therapy has been discussed. Many case reports have also described treatment effects of allo-HSCT in patients with hematologic malignancies and active solid tumors.

However, pathogenic NFKB1 variants have never been reported in the Japanese population. We present a 29-year-old Japanese woman with CVID.

We report a case of isolated CNS recurrence of bilateral PTL. Our patient achieved complete response (CR) after rituximab-combination chemotherapy for PTL.

It is widely acknowledged that the ascorbate biosynthesis in the photosynthetic tissues of land plants is governed by light-mediated regulation of the D-mannose/L-galactose (D-Man/L-Gal) pathway. At the core of this light-dependent regulation lies the VTC2 gene, encoding the rate-limiting enzyme GDP-L-Gal phosphorylase.

For each procedure, the indications, postoperative course, and treatment results were examined retrospectively.
Methods: Of 1,456 patients with PTC (maximum tumor diameter >1 cm) who received initial treatment between 1993 and 2013, we reviewed 51 patients.
