AI Article Synopsis
- The study investigates the role of polyamines in colorectal cancer (CRC), focusing on how their levels change during cancer development and treatment using a traditional Chinese medicine called Aidi.
- Using a rat model induced with CRC, researchers measured plasma polyamine levels and applied Lasso regression to identify key markers that can differentiate between healthy, CRC, and treated rats.
- Results showed that CRC disrupts polyamine metabolism, but Aidi treatment restores normal levels, indicating the potential of plasma polyamine profiling for early CRC diagnosis and treatment monitoring.
Article Abstract
As an important biomarker for cancer, polyamine levels in body fluid could be employed for monitoring the colorectal cancer (CRC), however the role of polyamines in the development and therapeutics phases of CRC remains uncertain. In this paper, the relationship between polyamines and CRC development and therapeutics had been investigated by the study of changes in plasma polyamine levels during the precancerous, developmental and treatment phases of CRC. After inducing CRC in Wistar rats by intraperitoneal injection of 1, 2-dimethylhydrazine, the animals were given a traditional Chinese medicine, Aidi injections. Firstly, the polyamine levels in the plasma of CRC, healthy and medicated rats were measured by UHPLC-MS/MS assay. In addition, Lasso regression analysis was used for screening and confirming the key markers, which can be employed for distinguishing the healthy and CRC rats as well as the CRC and medication rats. The results obtained showed that polyamine metabolism had been disrupted by CRC but returned to normal levels following Aidi injections and, in particular, putrescine and agmatine were closely correlated with CRC. Our results demonstrate the potential value of plasma polyamine metabolic profiling during the early diagnosis and medical treatment of CRC. Also, the integrated method of polyamine metabolite target analysis and lasso regression analysis can be applied in metabolomics for seeking the differential metabolites.

Effect of intracanal cryotherapy on post-operative pain in single-visit endodontic retreatment: a randomized clinical trial.
BMC Oral Health
December 2024
School of Dentistry, The University of Queensland, Brisbane, Australia.
Background: This randomized clinical trial aimed to evaluate the effect of intracanal cryotherapy with 2-4 °C normal saline irrigation on post-operative pain after single-visit non-surgical root canal retreatment.
Methods: Forty-six single-rooted, single-canal teeth requiring non-surgical root canal retreatment were randomly assigned to two groups (n = 23): a cryotherapy group and a control group. All the treatments were completed during a single visit.
Prebiotics and iron fortification among women of reproductive age group - Is there an association with liver and renal function tests?

Iron fortification compounds are of special interest to treat iron deficiency anemia, however, the dose-response effects of these fortificants on liver and renal functions have not been extensively reported in human subjects. The present study determines the effects of prebiotics and iron fortificants on liver function tests (LFTs) and renal function tests (RFTs) among women of reproductive age (WRA). A double-blind randomized controlled trial was performed for the duration of 90 days.

Polyamine Seed Priming: A Way to Enhance Stress Tolerance in Plants.

Polyamines (PAs), such as putrescine, spermine, and spermidine, are bioactive molecules that play a vital role in plant responses to stresses. Although they are frequently applied to achieve higher levels of stress tolerance in plants, their function in seed biology is still not fully understood. PAs have been described in only a limited number of studies as seed priming agents, but most of the data report only the physiological and biochemical PA effects, and only a few reports concern the molecular mechanisms.
