Contributions of Non-Neuronal Cholinergic Systems to the Regulation of Immune Cell Function, Highlighting the Role of α7 Nicotinic Acetylcholine Receptors.

Loewi's discovery of acetylcholine (ACh) release from the frog vagus nerve and the discovery by Dale and Dudley of ACh in ox spleen led to the demonstration of chemical transmission of nerve impulses. ACh is now well-known to function as a neurotransmitter. However, advances in the techniques for ACh detection have led to its discovery in many lifeforms lacking a nervous system, including eubacteria, archaea, fungi, and plants.

Evaluation of time-to-onset and outcome of cardiac adverse events related to pembrolizumab using post-marketing surveillance in Japanese patients.

Background: Pembrolizumab has been widely used in patients since its release, but information on cardiac Adverse Events (AEs) related to pembrolizumab remains lacking, particularly in Japanese populations.

Objectives: This study aims to evaluate time to onset, incidence rates, and outcomes for pembrolizumab-induced cardiac AEs in patients with cancer using the Japanese Adverse Drug Event Report database.

Methods: We analysed data for the period from April 2004 to March 2022.

The Roles of Fibrinolytic Factors in Bone Destruction Caused by Inflammation.

Chronic inflammatory diseases, such as rheumatoid arthritis, spondyloarthritis, systemic lupus erythematosus, Crohn's disease, periodontitis, and carcinoma metastasis frequently result in bone destruction. Pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, and IL-17 are known to influence bone loss by promoting the differentiation and activation of osteoclasts. Fibrinolytic factors, such as plasminogen (Plg), plasmin, urokinase-type plasminogen activator (uPA), its receptor (uPAR), tissue-type plasminogen activator (tPA), α2-antiplasmin (α2AP), and plasminogen activator inhibitor-1 (PAI-1) are expressed in osteoclasts and osteoblasts and are considered essential in maintaining bone homeostasis by regulating the functions of both osteoclasts and osteoblasts.

Traditional japanese diet score and the sustainable development goals by a global comparative ecological study.

Background: Reducing the environmental impact of the food supply is important for achieving Sustainable Development Goals (SDGs) worldwide. Previously, we developed the Traditional Japanese Diet Score (TJDS) and reported in a global ecological study that the Japanese diet is associated with reducing obesity and extending healthy life expectancy etc. We then examined the relationship between the TJDS and environmental indicators.

Spasmolytic Effect of Flopropione Does Not Involve Catechol-O- methyltransferase (COMT) Inhibition.

Flopropione (Flo) has been used for gallstone and urolithiasis as a spasmolytic agent almost exclusively in Japan. According to the package insert, its main mechanism is catechol-O-methyltransferase (COMT) inhibition and anti-serotonergic effect. This is obviously contrary to pharmacological common sense, but it is described that way in pharmacology textbooks and occurs in questions in the National Examination for Pharmacists in Japan.

The impact of energy and protein intake on rehabilitation efficiency in convalescent patients.

Background And Objectives: It is well known that more than 40% of patients in the convalescent rehabilitation settings suffer from malnutrition, and that appropriate nutrition management can improve rehabilitation outcomes.

Methods And Study Design: In this study, we used a change in motor score of Functional Independent Measure (FIM-M) of convalescent rehabilitation to investigate whether daily energy intake could influence the rehabilitation outcomes. Of the 217 patients hospitalized in our convalescent rehabilitation ward (CRW) between September 2016 and February 2017, 162 met the eligibility criteria for this study.

α2-Antiplasmin is associated with macrophage activation and fibrin deposition in a macrophage activation syndrome mouse model.

Macrophage activation syndrome (MAS) is a life-threatening condition, characterized by cytopenia, multi-organ dysfunction, and coagulopathy associated with excessive activation of macrophages. In this study, we investigated the roles of alpha2-antiplasmin (α2AP) in the progression of MAS using fulminant MAS mouse model induced by toll-like receptor-9 agonist (CpG) and D-(+)-galactosamine hydrochloride (DG). α2AP deficiency attenuated macrophage accumulation, liver injury, and fibrin deposition in the MAS model mice.

Cholecystokinin-Induced Duodenogastric Bile Reflux Increases the Severity of Indomethacin-Induced Gastric Antral Ulcers in Re-fed Mice.

Background/aims: We examined the involvement of cholecystokinin (CCK) in the exacerbation of indomethacin (IND)-induced gastric antral ulcers by gastroparesis caused by atropine or dopamine in mice.

Methods: Male mice were fed for 2 h (re-feeding) following a 22-h fast. Indomethacin (IND; 10 mg/kg, s.

Variations in the inner core affect the pharmacokinetics of indomethacin-encapsulated polymeric micelles.

Hydrophobic ion pairing (HIP) is a drug encapsulation technology that uses electrostatic interactions between a drug and an additive. However, although polymeric micelles can encapsulate hydrophobic drugs in the core, the encapsulated drug often leaks. Therefore, we designed polymeric micelles with HIP functionalized in a hydrophobic inner core using three diblock copolymers comprising polypeptides with different ratios of polar and hydrophobic amino acids and polyethylene glycol (PEG) to encapsulate indomethacin (IND).

Role of transient receptor potential vanilloid 4 channels in an ovalbumin-induced murine food allergic model.

The prevalence of food allergy (FA) has increased worldwide but an effective therapeutic strategy has not been established. Transient receptor potential vanilloid 4 (TRPV4), a mechanosensitive nonselective cation channel, is mainly expressed in the epithelium of various organs. The present study investigated the role of TRPV4 in the pathogenesis of an ovalbumin (OVA)-induced FA model in mice.

Hydrolytic dynamic kinetic resolution of racemic 3-phenyl-2-oxetanone to chiral tropic acid.

Tropic acid was synthesized in a good yield and with high enantioselectivity (81% ee) under non-biphasic conditions the novel hydrolytic dynamic kinetic resolution of racemic 3-phenyl-2-oxetanone (tropic acid β-lactone) in the presence of a chiral quaternary ammonium phase-transfer catalyst and strongly basic anion exchange resin as the hydroxide ion donor.

Role of the Cytosolic Domain of the a3 Subunit of V-ATPase in the Interaction with Rab7 and Secretory Lysosome Trafficking in Osteoclasts.

We previously reported that the a3 subunit of proton-pumping vacuolar-type ATPase (V-ATPase) interacts with Rab7 and its guanine nucleotide exchange factor, Mon1a-Ccz1, and recruits them to secretory lysosomes in osteoclasts, which is essential for anterograde trafficking of secretory lysosomes. The a3 subunit interacts with Mon1a-Ccz1 through its cytosolic N-terminal domain. Here, we examined the roles of this domain in the interaction with Rab7 and trafficking of secretory lysosomes.

Japanese Nationwide Comparative Survey of Medication Guidance Provided by Certified and Uncertified Palliative Care Pharmacists.

Background: As members of a medical team, pharmacists are expected to provide optimal patient-centered, evidence-based pharmacotherapy. In Japan, in consideration of the importance of palliative care, a system was initiated for certifying palliative care pharmacists in 2010. However, no studies have evaluated the usefulness of board certification in palliative pharmacy.

Disproportionality Analysis of Stomatitis Associated with Anticancer Drugs Using the Japanese Adverse Drug Event Report Database.

Introduction: Anticancer drug-induced stomatitis can affect a patient's quality of life and the continuation of drug treatment. Although there have been reports of the occurrence of stomatitis associated with anticancer agents in clinical trials, few Japanese participants have been enrolled in clinical trials and have not been sufficiently investigated. In addition, there has been little attention on research on anticancer drugs associated with stomatitis by patient stratification with different carcinogenic sites.

A case of rapidly progressing sarcomatous intrahepatic cholangiocarcinoma with suddenly appearing lymph node metastasis.

Background: The sarcomatous variant of carcinoma is relatively rare in intrahepatic cholangiocarcinoma (ICC). Sarcomatous ICC (SICC) is associated with a poorer prognosis compared with ICC. SICC is rarely diagnosed before surgery due to non-descriptive findings; it progresses rapidly, resulting in miserable prognosis.

[Intracellular Mechanism of Gastric Acid Secretion: What is the True Switch?].

In 1985, I was accepted as postdoc by Professor Forte of UC Berkeley. He discovered H,K-ATPase and established the membrane recycling theory as the activation mechanism for acid secretion using whole animals. H,K-ATPase is an enzyme that exchanges H with K.

Impact of multiple H/D replacements on the physicochemical properties of flurbiprofen.

Although deuterium incorporation into pharmaceutical drugs is an attractive way to expand drug modalities, their physicochemical properties have not been sufficiently examined. This study focuses on examining the changes in physicochemical properties between flurbiprofen (FP) and flurbiprofen- (FP-), which was successfully prepared by direct and multiple H/D exchange reactions at the eight aromatic C-H bonds of FP. Although the effect of deuterium incorporation was not observed between the crystal structures of FP and FP-, the melting point and heat of fusion of FP- were lower than those of FP.
