A phase II study of zandelisib in patients with relapsed or refractory indolent non-Hodgkin lymphoma: ME-401-K02 study.

Zandelisib, a selective, potent PI3Kδ inhibitor, demonstrated favourable outcomes in patients with relapsed or refractory follicular lymphoma in a global phase II study. This phase II study evaluated the efficacy and safety of zandelisib for relapsed or refractory follicular lymphoma or marginal zone lymphoma. Sixty-one patients received zandelisib orally at 60 mg daily continuously in the first two 28-day cycles, followed by intermittent dosing on Days 1-7 following each cycle until progressive disease or unacceptable toxicity.

Interplay between Pitx2 and Pax7 temporally governs specification of extraocular muscle stem cells.

Gene regulatory networks that act upstream of skeletal muscle fate determinants are distinct in different anatomical locations. Despite recent efforts, a clear understanding of the cascade of events underlying the emergence and maintenance of the stem cell pool in specific muscle groups remains unresolved and debated. Here, we invalidated Pitx2 with multiple Cre-driver mice prenatally, postnatally, and during lineage progression.

Management of patients after total knee arthroplasty using mechanical prophylaxis and reduced doses of edoxaban: A retrospective cohort study.

Objective: Edoxaban is given as pharmacologic prophylaxis alone or in combination with mechanical prophylaxis for venous thromboembolism after total knee arthroplasty. Several choices are made regarding edoxaban dosages when used in combination with mechanical prophylaxis. This study aimed to compare efficacy and safety in patients who received edoxaban with elastic stockings after total knee arthroplasty between those who received the standard dose, including those who received a reduced dose after meeting dose reduction criteria, and those who received reduced doses without dose reduction criteria.

A modified high-resolution melting-based assay (HRM) to identify the SARS-CoV-2 N501Y variant.

High-resolution melting (HRM) analysis is a PCR-based method that can be used as a screening assay to identify SARS-CoV-2 variants. However, conventional HRM assays hardly detect slight melting temperature differences at the A-T to T-A transversion. As the N501Y substitution results from A-T to T-A transversion in A23063, few or no studies have shown that a conventional HRM assay can identify N501Y variants.

Rapid Identification of SARS-CoV-2 Omicron BA.5 Spike Mutation F486V in Clinical Specimens Using a High-Resolution Melting-Based Assay.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron subvariant BA.5 emerged as of February 2022 and replaced the earlier Omicron subvariants BA.1 and BA.

Cubam receptor-mediated endocytosis in hindgut-derived pseudoplacenta of a viviparous teleost (Xenotoca eiseni).

Nutrient transfer from mother to embryo is essential for reproduction in viviparous animals. In the viviparous teleost Xenotoca eiseni (family Goodeidae), the intraovarian embryo intakes the maternal component secreted into the ovarian fluid via the trophotaenia. Our previous study reported that the epithelial layer cells of the trophotaenia incorporate a maternal protein via vesicle trafficking.

Efficacy and Safety of HP-3070, an Asenapine Transdermal System, in Patients With Schizophrenia: A Phase 3, Randomized, Placebo-Controlled Study.

Objective: Asenapine is a second-generation antipsychotic used to treat individuals with schizophrenia. This phase 3 study assessed efficacy and safety of HP-3070, an asenapine transdermal system (patch), in adults with schizophrenia.

Methods: In this inpatient study, a 3- to 14-day screening/single-blind run-in washout period was followed by a 6-week double-blind period wherein patients with acutely exacerbated schizophrenia (DSM-5 criteria) were randomized 1:1:1 and received HP-3070 7.

Transient and lineage-restricted requirement of Ebf3 for sternum ossification.

Osteoblasts arise from bone-surrounding connective tissue containing tenocytes and fibroblasts. Lineages of these cell populations and mechanisms of their differentiation are not well understood. Screening enhancer-trap lines of zebrafish allowed us to identify Ebf3 as a transcription factor marking tenocytes and connective tissue cells in skeletal muscle of embryos.

Public Relations and Communication Strategies in Construction of Large-Scale Cohorts and Biobank: Practice in the Tohoku Medical Megabank Project.

The Tohoku Medical Megabank Project was designed as part of the national reconstruction project for addressing the damage from the 2011 Great East Japan Earthquake. It is an integrated project involving the genome cohort study of 150,000 participants, integrated biobank construction, and multi-omics analyses. Public relations and communication activities emerged to be extremely important in the successful development of this project.

Genome analyses for the Tohoku Medical Megabank Project towards establishment of personalized healthcare.

Personalized healthcare (PHC) based on an individual's genetic make-up is one of the most advanced, yet feasible, forms of medical care. The Tohoku Medical Megabank (TMM) Project aims to combine population genomics, medical genetics and prospective cohort studies to develop a critical infrastructure for the establishment of PHC. To date, a TMM CommCohort (adult general population) and a TMM BirThree Cohort (birth+three-generation families) have conducted recruitments and baseline surveys.

Giantin is required for coordinated production of aggrecan, link protein and type XI collagen during chondrogenesis.

Extracellular matrix (ECM) constitutes a proper micro-environment for cell proliferation, migration and differentiation, as well as playing pivotal roles in developmental processes including endochondral ossification. Cartilage ECM is mainly composed of fibrous proteins, including collagen, proteoglycan, and hyaluronan. Because almost all ECM components are transported by intracellular vesicular transport systems, molecules that mediate vesicle transport are also important for endochondral ossification.

Inflammation aggravates heterogeneity of ventricular repolarization in children with Kawasaki disease.

Kawasaki disease complicates with myocarditis and vasculitis. Even if myocarditis is asymptomatic, heterogeneity of ventricular repolarization may be increased in the acute phase. We evaluated whether the change in repolarization characteristics can be used as a predictor for myocarditis and coronary lesions.

Ventricular repolarization lability in children with Kawasaki disease.

Kawasaki disease (KD) is an acute febrile disease of unknown etiology that develops in children and is sometimes accompanied by myocardial dysfunction and systemic vasculitis. However, myocardial repolarization lability has not yet been fully investigated. Thus, the objective of this study was to evaluate myocardial repolarization lability (QT variability index-QTVI) based on the body surface electrocardiograms in the acute and recovery phases.

Beat-to-beat QT interval variability in children: normal and physiologic data.

Background: QT interval variability provides information on ventricular vulnerability. However, QT interval variability in children has not been adequately evaluated.

Methods: One hundred seventy-three consecutive nursing infants and children (male-female, 106:67) up to school age with no intrinsic cardiac disease were included in this study, and they were categorized into 6 age-related groups.

High-voltage testing of a 500-kV dc photocathode electron gun.

A high-voltage dc photocathode electron gun was successfully conditioned up to a voltage of 550 kV and a long-time holding test for 8 h was demonstrated at an acceleration voltage of 500 kV. The dc photocathode electron gun is designed for future light sources based on energy-recovery linac and consists of a Cockcroft-Walton generator, a segmented cylindrical ceramic insulator, guard-ring electrodes, a support-rod electrode, a vacuum chamber, and a pressurized insulating gas tank. The segmented cylindrical ceramic insulator and the guard-ring electrodes were utilized to prevent any damage to the insulator from electrons emitted by the support-rod electrode.

Achievement of ultralow emittance beam in the accelerator test facility damping ring.

For high luminosity in electron-positron linear colliders, it is essential to generate low vertical emittance beams. We report on the smallest vertical emittance achieved in single-bunch-mode operation of the Accelerator Test Facility, which satisfies the requirement of the x-band linear collider. The emittances were measured with a laser-wire beam-profile monitor installed in the damping ring.

Steroid therapy reduces mesangial matrix accumulation in advanced IgA nephropathy.

Background: Steroid therapy for IgA nephropathy (IgAN) has been reported to ameliorate the long-term prognosis of IgAN, but its mode of action has not been fully elucidated. In this study, we examined the effect of steroids on glomerular morphological changes in IgAN.

Methods: We examined 16 patients with biopsy-proven IgAN (male/female =11/5, mean age 32.

Extremely low vertical-emittance beam in the accelerator test facility at KEK.

Electron beams with the lowest, normalized transverse emittance recorded so far were produced and confirmed in single-bunch-mode operation of the Accelerator Test Facility at KEK. We established a tuning method of the damping ring which achieves a small vertical dispersion and small x-y orbit coupling. The vertical emittance was less than 1% of the horizontal emittance.

The product of duration and amount of proteinuria (proteinuria index) is a possible marker for glomerular and tubulointerstitial damage in IgA nephropathy.

Background/aims: IgA nephropathy (IgAN) is one of the major causes for chronic renal failure (CRF). Presence of massive proteinuria, hypertension, increased serum creatinine level and sclerotic histopathological changes of the glomerulus are known to be determinants for the progression of CRF. However, the relationships between duration of proteinuria/hematuria and histopathological changes, which may be correlated with the renal prognosis, have not been clarified.

Measurement of structure-dependent K+ --> &mgr;(+)nu(&mgr;)gamma decay.

We report the first measurement of a structure-dependent component in the decay K+-->&mgr;(+)nu(&mgr;)gamma. Using the kinematic region where the muon kinetic energy is greater than 137 MeV and the photon energy is greater than 90 MeV, we find that the absolute value of the sum of the vector and axial-vector form factors is |F(V)+F(A)| = 0.165+/-0.
