Use of Flame Atomic Absorption Spectrometry in Diagnosis of Cancerous and Non-Cancerous Breast Tissues: Comparison of Metal Concentrations

open access: yes, 2010
Metals play important roles for cellular functions and also for generating oxidative DNA damages. Furthermore, they are considered to act not only as carcinogens but also as co-carcinogens which activate carcinogenic chemicals.

Development of a reusuable atomic oxygen sensor using oxide thick films

open access: yes, 2009
The aim of this project was to develop a thick film sensor made of zinc oxide that would accurately respond to various fluxes of atomic oxygen (AO), allowing it to be regenerated after saturation.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

open access: yesMolecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

ADP‐ribosylation: An emerging regulator of the epigenome

open access: yesMolecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Rapid Analysis of 129I in Natural Water Samples Using Accelerator Mass Spectrometry

open access: yes, 2021
A rapid and simple co-precipitation method for iodine separation from natural samples was developed for determination of I-129 using accelerator mass spectrometry (AMS). The method includes three steps, i.e.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Raman spectral band imaging for the diagnostics and classification of canine and feline cutaneous tumors

open access: yesVeterinary Quarterly
This study introduces Raman imaging technique for diagnosing skin cancer in veterinary oncology patients (dogs and cats). Initially, Raman spectral bands (with specificity to certain molecular structures and functional groups) were identified in formalin-
