Utilization of ICT in Physical Education Classes ? Using a Heart Rate Sensor and Tablet ?
In this report, we introduce an example of a lesson practice where a small heart rate sensor and tablet are utilized. In a simulated physical education class for high school students, we conducted a shuttle run test with the aim of discerning exercise intensity and physical burden. Runners were fitted with a heartbeat sensor, with their heart rates monitored in real time on the tablet. A projector was used to project these data on a screen, helping us to visualize heart rate changes. In addition to showing an interest in the relationship between running speed and physiological burden, students who participated in the class also demonstrated curiosity with regard to a variety of other facets of the research, including the measuring instruments themselves and data analysis using PCs.departmental bulletin pape
Oligopeptide Transporter-1 is Associated with Fluorescence Intensity of 5-Aminolevulinic Acid-Based Photodynamic Diagnosis in Pancreatic Cancer Cells
[Background] The 5-aminolevulinic acid (ALA)-based photodynamic diagnosis is based on the accumulation of photosensitizing protoporphyrin IX in the tumor after ALA administration. However, the mechanisms connecting exogenous ALA and tumor fluorescence in pancreatic cancer remain unclear. We aimed to elucidate the mechanism underlying the ALA-induced fluorescent. [Methods] Human pancreatic duct epithelial cells (hPDECs) and pancreatic cancer cell lines were used. The expressions of ALA-associated enzymes and membrane transporters in these cell lines were investigated. ALA-induced fluorescence was also investigated. [Results] The expression of oligopeptide transporter-1 (PEPT-1), through which ALA is absorbed, was significantly higher in AsPC-1 cells and lower in MIA PaCa-2 cells than in hPDECs. AsPC-1 cells showed rapid and intense fluorescence after ALA administration, and that was attenuated by PEPT-1 inhibition. ALA-induced fluorescence was not sufficiently strong in MIA PaCa-2 cells to distinguish the cells from hPDECs. [Conclusion] We revealed the association of PEPT-1 with ALA-induced fluorescence. Cancers expressing PEPT-1 could be easily distinguished by this technique from normal cells. These findings help develop novel diagnostic modalities for pancreatic cancer.journal articl

Ultrasensitive ImmunoMag-CRISPR Lateral Flow Assay for Point-of-Care Testing of Urinary Biomarkers
Rapid, accurate, and noninvasive
detection of biomarkers in saliva,
urine, or nasal fluid is essential for the identification, early diagnosis,
and monitoring of cancer, organ failure, transplant rejection, vascular
diseases, autoimmune disorders, and infectious diseases. We report
the development of an Immuno-CRISPR-based lateral flow assay (LFA)
using antibody-DNA barcode complexes with magnetic enrichment of the
target urinary biomarkers CXCL9 and CXCL10 for naked eye detection
(ImmunoMag-CRISPR LFA). An intermediate approach involving a magnetic
bead-based Immuno-CRISPR assay (ImmunoMag-CRISPR) resulted in a limit
of detection (LOD) of 0.6 pg/mL for CXCL9. This value surpasses the
detection limits achieved by previously reported assays. The highly
sensitive detection method was then re-engineered into an LFA format
with an LOD of 18 pg/mL for CXCL9, thereby enabling noninvasive early
detection of acute kidney transplant rejection. The ImmunoMag-CRISPR
LFA was tested on 42 clinical urine samples from kidney transplant
recipients, and the assay could determine 11 positive and 31 negative
urinary samples through a simple visual comparison of the test line
and the control line of the LFA strip. The LFA system was then expanded
to quantify the CXCL9 and CXCL10 levels in clinical urine samples
from images. This approach has the potential to be extended to a wide
range of point-of-care tests for highly sensitive biomarker detection
