62±1.75) was larger than the NRO group (1.89±0.97; p<0.0001). At 1 and 6months, the MA density in the area with persistent oedema was significantly higher than in the area with improved oedema (1month p=0.0001, 6months p=0.029).

High MA density and extensive swelling may be characteristic of RO following treatment for DMO with intravitreal injection of either aflibercept or ranibizumab.

Importantly, the mechanical properties of individual cells can vary depending on local physical and biochemical cues in a time-dependent manner resulting in significant inter-cell heterogeneity. While several different methods have been developed to interrogate the mechanical properties of single cells, throughput to capture this heterogeneity remains an issue. Here, single-cell, high-throughput characterization of adherent cells is demonstrated using acoustic force spectroscopy (AFS). AFS works by simultaneously, acoustically driving tens to hundreds of silica beads attached to cells away from the cell surface, allowing the user to measure the stiffness of adherent cells under multiple experimental conditions. It is shown that cells undergo marked changes in viscoelasticity as a function of temperature, by altering the temperature within the AFS microfluidic circuit between 21 and 37 °C. In addition, quantitative differences in cells exposed to different pharmacological treatments specifically targeting the membrane-cytoskeleton interface are shown. Further, the high-throughput format of the AFS is utilized to rapidly probe, in excess of 1000 cells, three different cell lines expressing different levels of a mechanosensitive protein, Piezo1, demonstrating the ability to differentiate between cells based on protein expression levels.Rational design of nanosystems that target tumor microenvironment have attracted widespread attention. However, it is still a great challenge to make a multifunctional nanoplatform that actively and selectively interacts with tumor microenvironment, without causing toxicity to surrounding normal tissues. read more Herein, the biodegradable Fe-doped MoOx (FMO) nanowires are designed as an anti-tumor nanoreagent that possesses great photothermal conversion ability (48.5%) and magnetic properties for T1 weighted magnetic resonance imaging (MRI). Also, FMO can be used as a chemodynamic therapy (CDT) reagent to effectively catalyze the decomposition of H2 O2 and produce hydroxyl radical (·OH). At the same time, the consumption of glutathione will also enhance the CDT effect. More importantly, FMO presents pH-dependent degradation behavior rapid degradation at physiological pH, but relatively stable at acidic pH. In vivo anti-tumor experiment demonstrates that the FMO is able to effectively inhibit the tumor growth with minimal side effects. Generally speaking, these results indicate that the FMO has huge potential for MRI image-guided cancer therapy and promotes the clinical translation of nanodrugs.New radionuclide-labeled targeting nanocarrier systems have generated new opportunities for tumor treatment and imaging. Nevertheless, such therapeutic strategy is clinically unfeasible on anaplastic thyroid carcinoma (ATC) patients, because of lacking suitable targets and resistance to radiation. In order to figure out a potential treatment, immuno-histochemical staining is performed in human ATC tissue species and high expression of cluster determinant 44 (CD44) is found. Therefore, a CD44-targeted delivery system is designed and constructed by self-assembly of tyrosine (Tyr)-hyaluronic acid (HA)-polyethyleneimine (PEI), which can radiolabel 131/125 I and load a p53 mutant restoring regent, Prima-1. The 125 I-labeled nanocomposites display an impressive tumor imaging as well as a long radiation treatment cycle. The 131 I-labeled nanoparticles show remarkable anti ATC-tumor effects in vitro and in vivo, due to radiosensitization of Prima-1 by reactivation of the p53 mutants.

To determine bone mineral density (BMD) in psoriatic arthritis (PsA) patients, factors associated with undergoing BMD testing, and the effect of PsA clinical activity on BMD.

Patients attending the University of Toronto PsA Clinic with a BMD from cohort inception to January 2019 were included. Descriptive statistics summarized lumbar spine, femoral neck and total hip T-scores. Cox proportional hazard regression identified predictors for BMD testing. Logistic regression analysis determined odds of having normal (T-score ≥ -1.0) versus osteoporotic range BMD (T-score ≤ -2.5). A multi-state model determined factors associated with BMD state changes over time.

Of the 1479 patients, 214 had BMDs. Mean T-scores at the lumbar spine, femoral neck and total hip were -0.30±0.32, -1.10±1.04 and -0.45±0.42 respectively. Osteopenia and osteoporosis occurred in 45.27% and 12.94% of patients. Increasing age, menopause, elevated acute phase reactants, biologic, methotrexate and systemic glucocorticoid use were associated with a higher chance of undergoing BMD testing. Increased BMI and biologic use were associated with a lower chance of having osteoporotic range BMD. In multi-state analysis, polyarthritis may portend lower BMDs over time, although this did not achieve statistical significance due to low patient numbers.

The prevalence of osteopenia and osteoporosis in the PsA cohort were similar to the general population. Clinicians are using osteoporosis risk factors and PsA disease severity markers to select patients for BMD testing. Polyarticular disease may portend worse BMDs. Biologic use and increased BMI appear to have a protective effect.
