Notes

The multigenomic water biopsy biomarker with regard to neuroendocrine tumor illness outperforms CgA and contains medical as well as scientific utility.
Rupture of atherosclerotic plaques constitutes the major cause of thrombosis and acute ischemic coronary syndrome. Bone marrow-derived mesenchymal stem cells microvesicles (BMSCs-MVs) are reported to promote angiogenesis. This study investigated the role of BMSCs-MVs in stabilizing atherosclerotic plaques. BMSCs-MVs in mice were isolated and identified. The mouse model of atherosclerosis was established, and mice were injected with BMSCs-MVs via the tail vein. The macrophage model with high glucose and oxidative damage was established and then incubated with BMSCs-MVs. Nod-like receptor protein 3 (NLRP3) expression, pyroptosis-related proteins, and inflammatory factors were detected. Actinomycin D was used to inhibit the secretion of BMSCs-MVs to verify the source of microRNA-223 (miR-223). The binding relationship between miR-223 and NLRP3 was predicted and verified. BMSCs-MVs with knockdown of miR-223 were cocultured with bone marrow-derived macrophages with knockdown of NLRP3, and then levels of miR-223, NLRP3, pyroptosis-related proteins, and inflammatory factors were detected. BMSCs-MVs could reduce the vulnerability index of atherosclerotic plaques and intima-media thickness in mice, and inhibit pyroptosis and inflammation. BMSCs-MVs inhibited pyroptosis and inflammatory factors in macrophages. BMSCs-MVs carried miR-223 to inhibit NLRP3 expression and reduce macrophage pyroptosis, thereby stabilizing the atherosclerotic plaques.
This study aimed to explore the association between socioeconomic status and urinary incontinence (UI).

We used data from the three waves of the Taiwan Longitudinal Study on Aging. This study included 2458 women and 2866 men aged ≥50 years. We used logistic random effects models to examine the associations of interest, adjusting for demographics, health-related behaviors, disability, number of health conditions and prostate problems for men and numbers of children for women.

In adjusted analysis, women with secondary education least frequently reported UI compared with women with no formal education (adjusted odds ratio [AOR] 0.41, 95% confidence interval [95% CI] 0.22-0.79). Those with severe economic hardships (vs those with no economic hardships) had an increased risk of UI among men and women (AOR 2.71, 95% CI 1.72-4.25 and AOR 1.94, 95% CI 1.31-2.88, respectively). Compared with men doing mentally demanding jobs, service workers/salesperson and retired men were more prone to UI (AOR 2.67, 95% CI 1.14-6.36 and AOR 2.41, 95% CI 1.19-4.87, respectively). Further analysis showed that the associations of economic hardship with UI were attenuated when adjusting for access to healthcare.

No formal education in women and severe economic hardship in both the sexes were associated with an increased risk of UI among middle-aged and older persons. The disparities should be taken into account in interventions for prevention, treatment and management of UI. Geriatr Gerontol Int 2021; 21 245-253.

The shaping and orientation of the resulting system are carried out using a micellar template of a surfactant and a magnetic field. Submicron nickel fibres are used to impart unity to the plurality of individual-oriented nickel nanonetworks. The result is a single conductive coating on the surface of the glass, which has a transparency in the optical range. Investigations of the structure, chemical composition, morphology and electrical conductivity of the coating were performed.Expansion microscopy combined with single-molecule localization microscopy (ExSMLM) has a potential for approaching molecular resolution. Pifithrin-α price However, ExSMLM faces multiple challenges such as loss of fluorophores and proteins during polymerization, digestion or denaturation, and an increase in linkage error arising from the distance between the fluorophore and the target molecule. Here, we introduce a trifunctional streptavidin to link the target, fluorophore and gel matrix via a biotinylizable peptide tag. The resultant ExSMLM images of vimentin filaments demonstrated high labeling efficiency and a minimal linkage error of ∼5 nm. Our ExSMLM provides a simple and practical means for fluorescence imaging with molecular resolution.Nitrogen (N), potassium (K), and phosphorus (P) are essential macronutrients for plant growth and development, and their availability affects crop yield. Compared with N, the relatively low availability of K and P in soils limits crop production and thus threatens food security and agricultural sustainability. Improvement of plant nutrient utilization efficiency provides a potential route to overcome the effects of K and P deficiencies. Investigation of the molecular mechanisms underlying how plants sense, absorb, transport, and use K and P is an important prerequisite to improve crop nutrient utilization efficiency. In this review, we summarize current understanding of K and P transport and signaling in plants, mainly taking Arabidopsis thaliana and rice (Oryza sativa) as examples. We also discuss the mechanisms coordinating transport of N and K, as well as P and N.
To identify predictors of palliation for head and neck cancer treated with the "Hypo Trial" hypofractionated radiation therapy regimen in a clinical setting.

We retrospectively assessed 106 consecutive patients with incurable cancer, treated between January 2008 and December 2018. Regimen used was 30-36Gy in 5-6 biweekly fractions of 6Gy.

The prescription dose was 30Gy in 57 (53.8%) patients and 36Gy in 49 (46.2%) patients. 89.6% patients completed the prescribed treatment. With a median follow-up of 6.92 months, 79.2% of the patients experienced clinical palliation. Palliation was correlated with the radiation therapy dose (P = 0.05). Median overall and progression-free survival (OS, PFS) were 7 and 4.63 months, respectively. Achieving palliation was associated to OS (P = 0.01).

This short palliative hypofractionated scheme resulted in a high rate of palliation, with excellent compliance and acceptable toxicity. Our results show that radiation dose is a predictive factor for palliation.
