Each year, the proportion of thyroid cancer patients presenting with low-risk disease is increasing. The shift in the landscape of thyroid cancer presentation is forcing clinicians to re-evaluate not only management, but surveillance paradigms. During the follow-up, patients are stratified considering their response to treatment, and classified into one of the following response categories excellent biochemical incomplete, structural incomplete, or indeterminate. These categories reflect a real-time prognosis and thereby substantially influence and personalise disease management. Although at present, no guideline recommends stopping differentiated thyroid carcinoma (DTC) surveillance at any particular time point, the relatively low prevalence of treatment failures in low-risk patients may prompt early discontinuation of surveillance in this subgroup. Therefore this debate will present an overview of the controversies surrounding the surveillance of low-risk patients with DTC.Decidualization is a critical process for embryo implantation and pregnancy maintenance in humans. The homeobox gene HOXA10 has been widely studied in endometrial receptivity establishment and decidualization. MEIS1, a three-amino-acid loop extension (TALE) family homeobox gene, has been proven to be a co-factor for HOXA10 in mouse uterus. However, the interaction between MEIS1 and HOXA10 in the human decidual cells remains to be elucidated. siRNA and CRISPR-Cas9 were employed to knockdown and knockout MEIS1 in the cultured human endometrial stromal cells, and it was found that MEIS1 deficiency leads to impaired decidualization. The physical interaction between the MEIS1 and HOXA10 in human endometrium stromal cell was confirmed by immunoprecipitation. Moreover, KAT2B and ETA were proved to be downregulated in the absence of MEIS1, and Luciferase reporter and ChIP assays demonstrated that MEIS1-HOXA10 complex binds to the promoters of KAT2B and ETA and regulates their activity. Overexpression of KAT2B and ETA can partially rescue the decidualization defects in MEIS1 knockout HESCs. Taken together, these data suggest that MEIS1 plays an indispensable role in decidualization in human endometrial stromal cells, and MEIS1 interacts with HOXA10 to regulate the downstream genes, such as KAT2B and ETA. These findings will contribute to our understanding about the regulatory network in the process of decidualization in humans.Developing nursing students' knowledge and practice of infection prevention and control (IPC) is fundamental to safe healthcare. A two-phase descriptive, mixed-method study conducted within a Bachelor of Nursing program at an Australian university aimed to explore (i) theoretical knowledge of IPC, highlighting hand hygiene, of nursing students and; (ii) nursing students' and clinical facilitators' perceptions of factors influencing these practices during clinical placement. Phase One utilised an anonymous validated questionnaire assessing students' knowledge; identifying variables influencing students' IPC practices, subjected to descriptive and inferential analysis. Phase Two were semi-structured interviews exploring clinical facilitators' experiences/perceptions of students during clinical placement, analysed thematically. Students' demonstrated satisfactory knowledge of IPC in their second and third year, but clinical facilitators perceived that. students lacked awareness of the importance of these practices. Five themes arose from the interviews (i) understanding workplace culture; (ii) students' modelling local behaviour; (iii) enhancing and consolidating knowledge for practice; (iv) adjusting to practice reality and; (v) accessing additional hand hygiene resources. Factors specific to workplace setting and culture were perceived to influence nursing students' socialisation. Future practice/education strategies could address these factors by ensuring students receive adequate supervision during clinical placement, and having strong advocates/role models present in the workplace. Polycyclic aromatic hydrocarbons (PAHs) are among the most hazardous pollutants and have attracted significant attention in the last decades. Up to now, rapid and on-site trace detection of PAHs remains a challenging issue. Here, taking advantage of the high sensitivity and reliable qualification of Surface-enhanced Raman Spectroscopy (SERS), we firstly carried out trace analyses of 16 typical PAHs in water at concentrations as low as 100-0.1 μg/L, depending on the number of aromatic rings of the molecule. Furthermore, owing to the simplicity of the liquid-liquid extraction (LLE) step, the sensitivity was further improved 2-3 orders of magnitude, and the lowest detectable concentrations were 100, 50, and 5 ng/L for anthracene, pyrene, and benzo[a]pyrene (the three PAHs typically found in heavily polluted waters), respectively. The LLE-SERS approach was successfully applied to the qualitative and quantitative analyses of different (ocean and coast) water samples being spiked by these three PAHs, which showed great promise as a trace detection tool of PAHs under water environments having different contaminant matrices. V.BACKGROUND Epigenetic alternations of microRNAs (miRNAs) can contribute to the pathogenesis and progression of rheumatoid arthritis (RA). This study aimed to measure the expression level of peripheral blood miRNAs, as well as their target mRNAs, in RA patients and healthy controls (HCs), and to evaluate the potential of miRNAs as promising non-invasive biomarkers of treatment response. METHODS The peripheral expression of miRNAs, including miR-146a, miR-146b, miR-150, miR-155, miR-125a-5p, miR-223, miR-26a, and miR-21, as well as their target mRNAs, was analyzed in 90 RA patients and 30 HCs via quantitative real-time polymerase chain reaction (RT-PCR) assay. Disodium Phosphate solubility dmso We compared differences between the patients in terms of good response (GR; n = 55) and poor response (PR; n = 35) to the conventional therapeutic approach. RESULTS All miRNAs were significantly overexpressed in RA patients. The expression of miR-155, miR-150, miR-146a, miR-146b, miR-125a-5p, and miR-223 increased in both groups of RA patients, compared to HCs, and miR-26a and miR-21 were the only upregulated miRNAs in the GR group versus HCs.
