Safety and effectiveness of mogamulizumab in relapsed or refractory CC chemokine receptor 4-positive peripheral T-cell lymphoma and relapsed or refractory cutaneous T-cell lymphoma: A post-marketing surveillance in Japan.

Mogamulizumab is a humanized antibody targeting CC chemokine receptor 4 (CCR4). This post-marketing surveillance was conducted in Japan as a regulatory requirement from 2014 to 2020 to ensure the safety and effectiveness of mogamulizumab in patients with relapsed or refractory (r/r) CCR4-positive peripheral T-cell lymphoma (PTCL) or r/r cutaneous T-cell lymphoma (CTCL). Safety and effectiveness data were collected for up to 31 weeks after treatment initiation.

Local pH mapping in the cell adhesion nano-interfaces on a pH-responsive fluorescence-dye-immobilized substrate.

Cell-substrate adhesion nano-interfaces can, in principle, exhibit a spatial distribution of local pH values under the influence of the weakly acidic microenvironment of glycocalyx grafted on lipid bilayer cell membrane which is compressed and closely attached to culture substrate in the vicinity of integrin-adhesion complexes. However, a simple local pH distribution imaging methodology has not been developed. In this study, to visualize the local pH distribution at the cell adhesion interface, we prepared glass substrates chemically modified with a pH-responsive fluorescent dye fluorescein isothiocyanate (FITC), observed the distribution of FITC fluorescence intensity at the adhesion interface of fibroblast (NIH/3T3) and cancer cells (HeLa), and compared the FITC images with the observed distribution of focal adhesions.

Safety and effectiveness of istradefylline as add-on therapy to levodopa in patients with Parkinson's disease: Final report of a post-marketing surveillance study in Japan.

Introduction: Istradefylline is approved in Japan and the US for treatment of Parkinson's disease (PD) in adult patients who experience the wearing-off phenomenon while receiving levodopa; however, safety and efficacy data for real-world clinical use are lacking.

Methods: We report the final results of a prospective, long-term, post-marketing surveillance study of istradefylline adjunct to levodopa for adults with PD experiencing the wearing-off phenomenon. Patients across 214 study sites initiating treatment with oral istradefylline once-daily 20- or 40-mg were followed-up for 1 year.

Safety and effectiveness of mogamulizumab in relapsed or refractory adult T-cell leukemia-lymphoma.

Objective: This prospective, observational, postmarketing surveillance was conducted to evaluate the safety and effectiveness of mogamulizumab, an anti-CC chemokine receptor 4 (CCR4) monoclonal antibody, in patients with CCR4-positive, relapsed or refractory (r/r) adult T-cell leukemia-lymphoma (ATL) in Japan.

Method: All patients were scheduled to receive intravenous infusions of mogamulizumab 1.0 mg/kg once weekly for 8 weeks, alone or in combination with other modalities.

Persistent random deformation model of cells crawling on a gel surface.

In general, cells move on a substrate through extension and contraction of the cell body. Though cell movement should be explained by taking into account the effect of such shape fluctuations, past approaches to formulate cell-crawling have not sufficiently quantified the relationship between cell movement (velocity and trajectory) and shape fluctuations based on experimental data regarding actual shaping dynamics. To clarify this relationship, we experimentally characterized cell-crawling in terms of shape fluctuations, especially extension and contraction, by using an elasticity-tunable gel substrate to modulate cell shape.

Safety and efficacy of mogamulizumab in patients with adult T-cell leukemia-lymphoma in Japan: interim results of postmarketing all-case surveillance.

We present the interim results of a postmarketing all-case surveillance study in patients with C-C chemokine receptor 4 (CCR4)-positive, relapsed or refractory adult T-cell leukemia-lymphoma (ATL) treated with the anti-CCR4 monoclonal antibody mogamulizumab since its 2012 launch in Japan. The safety and efficacy analysis populations comprised 484 and 442 patients, respectively. The ATL subtype was acute in 58.

A case of diffuse neurofibrillary tangles with calcification.

We report a 79-year-old female with atypical senile dementia with Fahr-type calcification. The patient started to show memory disturbance at the age of 75 years, followed by visual hallucination, stereotypy, personality changes such as irritability, aggression and disinhibition. Brain computed tomography (CT) demonstrated bilateral and symmetric calcification of the basal ganglia and thalamus.
