Glomerulonephritis, also known as nephritis syndrome (nephritis for short), is a common kidney disease. Previous research has proved that microRNAs (miRNAs) frequently regulate various diseases including nephritis. Nonetheless, the biological function and molecular mechanism of miR-17-5p are unclear in nephritis. In the current study, RT-qPCR analysis showed that miR-17-5p was downregulated in Ang II-induced podocytes. Also, according to the results from RT-qPCR analysis, CCK-8 assay, flow cytometric analysis, western blot analysis, and ELISA miR-17-5p elevation alleviated Ang II-induced podocyte injury. Besides, luciferase reporter assay, western blot and RT-qPCR analyses revealed that SMOC2 was targeted by miR-17-5p in Ang II-induced podocytes. Additionally, rescue assays demonstrated that overexpressed SMOC2 counteracted the influence of overexpressed miR-17-5p on cell injury of Ang II-induced podocytes. Moreover, our data suggested that miR-17-5p-SMOC2 axis regulated TGFβ and NF-κB signaling activation in Ang II-induced podocytes. SMOC2 regulated cell viability, apoptosis and extracellular matrix (ECM) deposition in Ang II-induced podocytes via TGFβ signaling, and SMOC2 regulated inflammation in Ang II-induced podocytes through NF-κB signaling. Overall, our study demonstrated that miRNA-17-5p restrained the dysfunction of Ang-II induced podocytes by suppressing SMOC2 via the NF-κB and TGFβ signaling.

Patient activation describes the knowledge, skills and confidence in managing one's own health. Promoting patient activation is being prioritized to reduce costs and adverse outcomes such as cardiovascular disease (CVD). see more The increasing prevalence of chronic kidney disease (CKD) presents a need to understand the characteristics that influence patient activation and the effect on health outcomes.

Cross-sectional study.

Patients with non-dialysis CKD recruited from 14 sites (general nephrology and primary care) in England, UK.

Patient activation was measured using the PAM-13. Demographic and health-related variables, self-reported symptom burden, health-related quality of life (HRQOL), socioeconomic status (SES), were assessed as determinants of patient activation. Major CVD risk factors included hypertension, dyslipidaemia, obesity and hyperkalaemia.

743 patients were included (eGFR 32.3 (

17.1)mL/min/1.73m

, age 67.8 (

13.9) years, 68% male). The mean PAM score was 55.1 (

14.4)/100. Most patients (60%) had low activation. Those with low activation were older (P<.001), had lower eGFR (P=.004), greater number of comorbidities (P=.026) and lower haemoglobin (P=.025). Patients with low activation had a 17% greater number of CVD risk factors (P<.001). Risk factors in those with low activation were being older (P<.001) and having diabetes (P<.001).

This study showed that only a minority of CKD patients are activated for self-management. Our findings help better understand the level of activation in these patients, particularly older individuals with multimorbidity, and further the knowledge regarding the characteristics that influence activation.

Herein, we report the first example of an LD/nucleus dual-targeted ratiometric fluorescent probe, CQPP, for monitoring polarity changes in the cellular microenvironment. Due to the donor-acceptor structure of CQPP, it offers ratiometric fluorescence emission and fluorescence lifetime signals that reflect polarity variations. Using nucleus imaging as a reference, CQPP was applied to report the increase in LD polarity and the homogenization of polarity between LDs and cytoplasm in the ferroptosis model. This LD/nucleus dual-targeted fluorescent probe shows the great potential of using fluorescence imaging to study ferroptosis and ferroptosis-related diseases.

Under-eye dark circles are a common condition observed in dermatology practice. Mesenchymal stromal cell-derived conditioned medium (MSC-CM) contains an array of growth factors and cytokines reported to promote periorbital rejuvenation and may be useful in removing the dark circle around the eyes.

The aim of the present study was to evaluate the safety and efficacy of developed bioactive formulation containing mesenchymal stromal cell-derived conditioned medium in reducing the under-eye dark circles.

We tested the safety profile of MSC-CM along with antioxidants, in vitro using human melanocytes cultures. The bioactive formulation containing MSC-CM was developed and tested for physicochemical parameters. The dermatological safety was evaluated by primary irritant patch-test under complete occlusion on healthy human subjects. To elucidate its safety and efficacy, monocentric, open-label, single-arm study was carried out in 20 Indian female subjects for the duration of 12weeks. Parameters such as eye puffand effective in reducing the under-eye dark circles and was beneficial in improving the overall appearance of the eye area.In the context of doping control, conventional direct chemical testing detects only a limited scope of target substances in equine biological samples. To expand the ability to detect doping agents and their detection windows, metabolomics has recently become a common approach for monitoring alteration of biomarkers caused by doping agents in relevant metabolic pathways. In horse racing, remarkable changes in metabolic profiles between the rest state and racing are likely to affect the identification of doping biomarkers. Previously, we reported a limited number of significantly upregulated metabolites after racing, based on a non-targeted metabolomics approach using out-of-competition and post-race equine plasma samples. In this study, we performed a more thorough analysis of the data set, using pathway analysis to establish a post-race biomarkers database (PBD) that includes upregulated and downregulated metabolites, their fold changes, and relevant pathways, with the main objective of improving our understanding of changes in physiological status related to horse racing.
