The mortality rate for acute kidney injury (AKI) due to sepsis remains high, and effective therapies based on its pathogenesis remain elusive. Macrophages are crucial for clearing bacteria from vital organs, including the kidney, under septic conditions. Excessive macrophage activation results in organ injury.

Recent studies have revealed that mammalian B cells ingest particulate Ags, such as bacteria, although little is known about the effect of this function on acquired immunity. We investigated the role of bacterium-phagocytosing B cells in acquired host immune responses. Cultured mouse liver B cells substantially phagocytosed serum-opsonized and produced IgM.

A microdevice for the measurement of the respiratory activity of cells was fabricated using a microfabricated Clark-type oxygen electrode. The oxygen electrode was completed in a dry state and was activated by introducing water necessary for the reduction of oxygen in the form of water vapor through an oxygen-permeable membrane, which significantly facilitated handling of the device even by nonspecialists. The use of a thin paper layer stabilized the current response and enabled stable continuous operation of the oxygen electrode without current disturbance caused by the evaporation of water.

Introduction: We report a randomized, double-blind, placebo-controlled, 4-week study to investigate the effect of empagliflozin on free fatty acids and blood ketone bodies in Japanese patients with type 2 diabetes mellitus.

Methods: Patients (baseline mean [standard deviation] glycated hemoglobin 7.91% [0.

Article Synopsis
  • This study examined how psychological stress affects exercise performance in mice, using a method called water-immersion restraint (WIR) stress.
  • Mice that experienced 2 hours of WIR stress struggled to efficiently use carbohydrates and lipids for energy during exercise, leading to significantly worse performance compared to control mice.
  • The research suggests that neutrophil bactericidal activity—which declines with increased stress—could be a helpful marker for assessing exercise performance in stressed individuals.

Aims: To investigate the efficacy and safety of empagliflozin in subgroups based on body mass index (BMI) and age, using a pooled data set from Japanese patients with type 2 diabetes mellitus (T2DM).

Methods: Pooled data from 1403 patients treated with empagliflozin at 10mg/day or 25mg/day in three clinical studies (≥52week treatment) were stratified by baseline BMI (<22, 22 to <25 and ≥25kg/m) and baseline age (<50, 50 to <65 and ≥65years).

Results: Empagliflozin at 10mg/day and 25mg/day reduced mean glycated hemoglobin (HbA1c) (-0.

Purpose: The purpose of this study was to assess the effect of renal impairment on the pharmacokinetic, pharmacodynamic, and safety profiles of empagliflozin, a sodium glucose cotransporter 2 (SGLT2) inhibitor, in Japanese patients with type 2 diabetes mellitus (T2DM).

Methods: In an open-label, parallel-group study, 32 Japanese patients with T2DM and different degrees of renal function (n = 8 per renal function category: normal renal function, estimated glomerular filtration rate [eGFR; Japanese equation] ≥90 mL/min/1.73 m(2); mild renal impairment, eGFR of 60-<90 mL/min/1.

Introduction: This study was designed to determine the efficacy and tolerability of empagliflozin monotherapy in Japanese patients with type 2 diabetes mellitus (T2DM).

Methods: Patients with glycosylated hemoglobin (HbA1c) ≥ 7.0 - ≤ 10% were randomized via an interactive web response system, and treated double-blind with empagliflozin 5, 10, 25, 50 mg, or placebo once daily for 12 weeks.

Introduction: To evaluate the pharmacodynamics, pharmacokinetics, safety and tolerability of empagliflozin in Japanese patients with type 2 diabetes mellitus.

Materials And Methods: In this 4-week, multiple dose, randomized, parallel-group, double-blind, placebo-controlled trial, patients (n = 100) were randomized to receive 1, 5, 10 or 25 mg of empagliflozin, or placebo once daily. Key end-points were urinary glucose excretion (UGE), fasting plasma glucose (FPG) and eight-point glucose profile.

A newborn female was transferred to our hospital presenting with severe respiratory distress. She underwent tracheal intubation and nasogastric tubing. Investigations revealed a congenital extrahepatic portosystemic shunt (CEPS) type 1, biliary atresia, heterotaxia, polysplenia, malrotation and a double aortic arch (DAA).

This randomized, placebo-controlled within dose groups, double-blind, single rising dose study investigated the safety, tolerability, pharmacokinetics and pharmacodynamics of 1 mg to 100 mg doses of empagliflozin in 48 healthy Japanese male subjects. Empagliflozin was rapidly absorbed, reaching peak levels in 1.25 to 2.
