Changes in Pharmacy Students' Awareness of Hepatitis B Patients through Patient Lectures as Humanity Education: Findings from Questionnaire Surveys of Face-to-Face and Simultaneous Remote Classes.

In 2020, the coronavirus disease 2019 (COVID-19) pandemic made social distancing compulsory. In patient lectures by hepatitis B patients (Patient Lectures)-a humanity education initiative that had traditionally been delivered face-to-face to assembled students-it was necessary to divide the students into two groups, one that attended the Patient Lectures in person (face-to-face group) and another that assembled in a separate room to view the delivered lecture simultaneously and remotely via a teleconferencing platform (remote group). To investigate possible changes in students' awareness of hepatitis B patients before (pre-) and after (post-) the lecture that year, the face-to-face and remote-attendance groups were analyzed separately.

Effect of Dietary Fiber on the Level of Free Hypoglycemic Agents in Vitro.

We studied the effect of dietary fibers (DFs) on the levels of free hypoglycemic agents in vitro, i.e., glimepiride and the biguanides buformin and metformin.

[Learning Strategy for Pharmacy Students to Develop Empathy for Hepatitis B Patients through a Lecture Presented by Patients Describing Their Daily Lives].

In April 2018, as part of their fifth-year pre-clinical education curriculum, pharmacy students at Setsunan University attended a lecture presented by hepatitis B patients and their lawyer entitled "Lecture by Hepatitis B Patients". This lecture was intended to help the students to understand the circumstances and difficulties encountered by hepatitis B patients on a daily basis. For this study, we conducted questionnaire surveys of the pharmacy students before and after the lecture.

Population pharmacokinetics of afatinib and exposure-safety relationships in Japanese patients with EGFR mutation-positive non-small cell lung cancer.

To investigate the exposure-safety relationships of afatinib in Japanese population, we performed population pharmacokinetics (PK) analysis of afatinib in Japanese advanced non-small cell lung cancer patients harboring epidermal growth factor receptor mutation. Plasma samples were collected at 0.5-1, 2-3, 8-12, and 24 h after oral afatinib (40 mg) administration on day 1 and day 8.

Cerebrospinal Fluid Penetration Rate and Efficacy of Afatinib in Patients with EGFR Mutation-positive Non-small Cell Lung Cancer with Leptomeningeal Carcinomatosis: A Multicenter Prospective Study.

Background: Afatinib is an effective first-line treatment for epidermal growth factor receptor (EGFR) mutation-positive advanced non-small cell lung cancer (NSCLC). However, few reports have addressed the influence of cerebrospinal fluid (CSF) penetration rate on the efficacy of afatinib in patients with central nervous system metastases. Therefore, we conducted a prospective multicenter trial to evaluate the CSF penetration rate and efficacy of afatinib in patients with EGFR mutation-positive NSCLC with leptomeningeal carcinomatosis.

Effect of dietary fibers on losartan uptake and transport in Caco-2 cells.

The objective of this study was to assess the effect of dietary fibers on the transport of losartan, an angiotensin II type 1 receptor blocker, in small intestinal cells. Using Caco-2 cells in vitro, losartan uptake and transport were evaluated in the presence of various fibers (cellulose, chitosan, sodium alginate and glucomannan). Dietary fibers caused a decrease in the uptake of losartan, with chitosan causing a significant reduction.

[Acid-neutralizing capacity of over-the-counter gastrointestinal medications].

  There is little information regarding the acid-neutralizing capacity of over-the-counter (OTC) gastrointestinal medicines. In this study, we assessed the acid-neutralizing capacity of OTC and prescribed gastrointestinal drugs based on the Japanese Pharmacopoeia 16th Edition. The acid-neutralizing capacity of the OTC drugs was calculated using experimental results for the crude materials found in the prescribed drugs based on OTC antacid quantity.

Effect of dietary fiber on the level of free angiotensin II receptor blocker in vitro.

The interaction between angiotensin II type 1 (AT1) receptor blockers (ARBs), such as losartan potassium (LO), candesartan (CA), and telmisartan (TE), and dietary fiber was studied as to the level of free ARB in vitro. When ARB was incubated with soluble (sodium alginate, pectin, and glucomannan) or insoluble (cellulose and chitosan) dietary fiber, the levels of free LO, TE, and CA decreased. This resulted only from mixing the dietary fiber with the ARBs and differed among the types of dietary fiber, and the pH and electrolytes in the mixture.

Intravenously administered 2'-deoxycytidine suppresses mouse myeloma tumor growth.

We examined the in vivo effects of intravenously administered 2'-deoxycytidine (dCyd) on tumor growth and survival time in mice bearing SP2/0-Ag14 (SP2/0) myeloma tumors. Administration of dCyd tended to decrease the tumor volume and significantly decreased the tumor weight. A single intravenous administration of dCyd significantly increased survival time of the tumor-bearing mice.

Changes in 2'-deoxycytidine levels in various tissues of tumor-bearing mice.

The nucleoside 2'-deoxycytidine (dCyd) increases in the plasma of cancer patients with poor prognoses. 5-fluorouracil (5FU) is one of the anti-cancer agents used in chemotherapy for patients whose plasma dCyd is elevated. We examined the free dCyd level in various tissues of mice, with and without tumors, and in mice with and without the administration of 5FU or of dCyd, and investigated the effects of dCyd in tumor-bearing animals.

2'-Deoxycytidine decreases the anti-tumor effects of 5-fluorouracil on mouse myeloma cells.

2'-Deoxycytidine (dCyd), a pyrimidine nucleoside found at high concentrations in the plasma of cancer patients with a poor prognosis after chemotherapy, is considered to be a biomarker for breast cancer. 5-Fluorouracil (5FU) is a nucleoside analog and is used as an anti-tumor agent in patients whose plasma dCyd concentrations are increased. Because both dCyd and 5FU are pyrimidine analogues, it is possible that they have pharmacokinetic/ pharmacodynamic interaction, by which the anti-cancer efficacy of 5FU would be reduced.
