3D printed hydrogels supported fibroblasts with excellent cell viability and proliferation. The dual crosslinkable hydrogel ink herein developed is versatile, easy to prepare, and suitable for 3D printing of bioscaffolds with highly tailored viscoelastic and mechanical properties applicable in a wide range of regenerative medicines.Mitochondrial proteins, most of which are encoded in the nucleus and the rest of which are regulated by the mitochondrial genome, play pivotal roles in essential cellular functions. However, fluorescent probes that can be used for monitoring mitochondrial proteins have not yet been widely developed, thereby severely limiting the exploration of the functions of proteins in mitochondria. Towards this end, here we propose a near-infrared (NIR) fluorescence probe MPP to effectively illuminate the dynamic changes in mitochondrial proteins in live cells under oxidative stress, with excellent temporal and spatial resolution. Of particular importance, MPP extends the study of the pharmacology involved in apoptosis induced by anti-cancer drugs (hydroxycamptothecin (HCPT), epirubicin (Epi) and cyclophosphamide (CPA)) for the first time. Furthermore, employing a protein-activatable strategy, this probe could serve as an excellent phototherapeutic agent in photodynamic therapy (PDT). Finally, in vivo experiments suggest that this versatile probe can be used to image tumors in HeLa tumor-bearing mice for 24 h, which demonstrates that our probe could play a dual role as a robust phototherapeutic and imaging agent.Antibiotic-resistant infections present significant challenges to patients. As a result, there is considerable need for new antibacterial therapies that eradicate pathogenic bacteria through non-conventional mechanisms. Our group has identified a series of halogenated phenazine (HP) agents that induce rapid iron starvation that leads to potent killing of methicillin-resistant Staphylococcus aureus biofilms. Here, we report the design, chemical synthesis and microbiological assessment of a HP-quinone ether prodrug model aimed to (1) eliminate general (off-target) iron chelation, and (2) release an active HP agent through the bioreduction of a quinone trigger. Here, we demonstrate prodrug analogue HP-29-Q to have a stable ether linkage that enables HP release and moderate to good antibacterial activities against lab strains and multi-drug resistant clinical isolates.Novel mitochondria targeting nanocarriers were prepared using triphenylphosphonium bromide (TPP)-modified whey protein isolate (WPI)-dextran (DX) conjugates by self-assembly method for astaxanthin mitochondria targeting delivery. The nanocarriers of astaxanthin-loaded WPI-DX and astaxanthin-loaded TPP-WPI-DX were 135.26 and 193.64 nm, respectively, which exhibited a spherical structure and good dispersibility. The mitochondria targeting nanocarriers had good stability in the stimulated blood fluid. In vitro experiments indicated that the TPP-modified nanocarriers could effectively realize lysosomes escape, and specifically accumulate in the cell mitochondria. Simultaneously, the astaxanthin-loaded nanocarriers could significantly reduce reactive oxygen species generation produced from hydrogen peroxide, protect the normal levels of the mitochondrial membrane potential, and dramatically promote the vitality of leukemia cells in mouse macrophage (RAW 264.7) cells. The present study highlights the promising application of mitochondria targeting nanocarriers for enhanced delivery of astaxanthin.
Apart from dietary restriction and medical therapy, the benefits of cardiovascular protection offered by polyunsaturated fatty acid (PUFA) supplements in patients with ESRD receiving maintenance dialysis remain unclear. learn more This systematic review and meta-analysis examined the effects of PUFAs on blood pressure, heart rate (HR), HR variability (HRV), and cardiovascular disease (CVD) prognosis.

We identified randomized controlled trials (RCTs) from Embase, PubMed (including MEDLINE), and Web of Science. We included seven RCTs that involved 724 patients with ESRD receiving dialysis and PUFA supplements.

The data indicated that compared with the control group, the PUFA group demonstrated decreased cardiovascular events (Peto odds ratio = 0.52, 95% confidence interval [CI] = 0.32 to 0.85, P = 0.009) and HRV (changes in the mean HR [mean difference = -2.59, 95% CI = -4.91 to -0.26, P = 0.03, I
= 0%]; mean RR interval [MD = 29.03, 95% CI = 5.43 to 52.63, P = 0.02, I
= 0%]; mean of the standard deviation of all normal RR intervals for all 5 min segments [MD = 2.73, 95% CI = 0.48 to 4.99, P = 0.02, I
= 0%], and square root of the mean of the sum of the squares of differences between adjacent intervals [MD = 2.03, 95% CI = 0.04 to 4.03, P = 0.05, I
= 0%]).

PUFA supplements appeared to improve CVD prognosis in patients receiving dialysis. Additional RCTs with longer follow-up periods need to clarify the benefits of PUFA supplements in this patient population.

This paper presents two 4-anchored MEMS plate resonators, with a resonance frequency of 2.2 MHz and 380 kHz, fabricated together with the required circuitry using a commercial 0.35 μm CMOS technology and then coated with poly-4-vinylheduorocumyl alcohol (P4V) via inkjet deposition. Such P4V constitutes a functionalization layer for specific acetone detection as a key step in the development of an integrated device for non-invasive diabetes diagnosis through exhaled human breath. The coated sensor system has been proven to increase the acetone injection response by 6-times compared to the uncoated platform and shows a cross-sensitivity to butane of 1  11. Experimental data show an acetone sensitivity of -0.012 ppm Hz-1 in the best case that, together with a measured frequency Allan deviation of 0.
