BACKGROUND: Screening with the fecal immunochemical test (FIT) is effective in reducing deaths from colorectal cancer (CRC). Since 2004, biennial FIT screening has been available to a target population in Taiwan as a national screening program. The objective of the current study was to identify the factors that influence willingness to undergo a confirmatory colonoscopy after a positive FIT, because related references in the published literature were scarce. METHODS: A semistructured questionnaire was based on the Health Belief Model (HBM) and a literature review...

Recently, immunochromatography test strips (ICTS) have been fully developed for point-of-care testing (POCT). However, the intrinsic limitations including non-quantitative detection of colloidal gold ICTS and low sensitivity of fluorescence ICTS (FICTS) significantly restrict their further application in clinical diagnosis. Taking advantages of rapid colorimetric qualitative detection and fluorescence quantitation, we designed a kind of sensitive and dual-mode magnetic FICTS (mFICTS) based on PLGA@Fe3O4 super-paramagnetic nanosphere (SPMN) probes quenching multiplex fluorescer on the test line through sandwich immunoreactions...

Aging is now at the forefront of major challenges faced globally, creating an immediate need for safe, widescale interventions to reduce the burden of chronic disease and extend human healthspan. Metformin and rapamycin are two FDA-approved mTOR inhibitors proposed for this purpose, exhibiting significant anti-cancer and anti-aging properties beyond their current clinical applications. However, each faces issues with approval for off-label, prophylactic use due to adverse effects. Here, we initiate an effort to identify nutraceuticals-safer, naturally-occurring compounds-that mimic the anti-aging effects of metformin and rapamycin without adverse effects...

Breast cancer is one of the major cause of cancer death in women worldwide. Therefore, it is urgent to discovery novel drugs or design effective treatments for this disease. However, the research and development of drugs by using only experimental methods is always time-consuming and expensive. With the development of computer science, some advanced computational methods can make full use of known knowledge to design candidate drugs, thereby reducing the cost and time of experimental testing. In this study, a computational method was proposed to identify novel candidates for breast cancer...

An estimated 1.7 million adults in the United States more than the age of 65 reside in long-term care nursing facilities (LTCNFs), and only 17% of them receive dental care. More than 83% of LTCNF residents require assistance with oral care. Adequate dental care is a preventative behavior for oral cancer. Adults more than age 65 will account for 60% of oral cancer-related deaths, despite an 80% cure rate for early diagnosis. This study sought to expand knowledge of the perceived benefits, barriers, and ability to perform or provide for oral health care and oral cancer screening as reported by Administrators and Directors of Nursing in LTCNFs...

INTRODUCTION: Cancer screening reduces mortality rates for breast, cervical, and colon cancer. Yet cancer screening rates for Latina women are lower than for non-Latino Whites, and below Healthy People 2020 goals. Additionally, Latinos face many health care access barriers. This study examined health care access and utilization in relation to cancer screening among low-income Latina women recruited from a high-risk area and enrolled in a navigation-plus-education intervention. METHODS: Latina women considered rarely or never screened for breast, cervical, or colorectal cancer were recruited from community-based organizations and events (N = 691)...

Background: Active surveillance (AS) is a widely adopted strategy to monitor men with low-risk, localized prostate cancer (PCa). Current AS inclusion criteria may misclassify as many as one in four patients. The advent of multiparametric magnetic resonance imaging (mpMRI) and novel PCa biomarkers may offer improved risk stratification. We performed a review of recently published literature to characterize emerging evidence in support of these novel modalities. Methods: An English literature search was conducted on PubMed for available original investigations on localized PCa, AS, imaging, and biomarkers published within the past 3 years...

Peptide drugs have been difficult to translate into effective therapies due to their low in vivo stability. Here, we report a strategy to develop peptide-based therapeutic nanoparticles by screening a peptide library differing by single-site amino acid mutations of lysine-modified cholesterol. Certain cholesterol-modified peptides are found to promote and stabilize peptide α-helix formation, resulting in selectively cell-permeable peptides. One cholesterol-modified peptide self-assembles into stable nanoparticles with considerable α-helix propensity stabilized by intermolecular van der Waals interactions between inter-peptide cholesterol molecules, and shows 68...
