Aims To examine the effect of three commercial intravesical formulations of glycosaminoglycan on in vitro inflammatory models of IC/BPS to better understand there effect on specific markers of disease. Methods Human urothelial cells (HTB-4) were cultured under four conditions in the presence or absence of commercial GAG formulations. Cells were cultured under a basal condition or pre-treated with protamine sulfate (100 ng/ml) (damages the endogenous glycosaminoglycan layer), hydrogen peroxide (1%) (a metabolic stressor) or TNFα (10 ng/ml) (creating an inflammatory environment). Each of these four culture conditions was then treated with one of three GAG formulations, CystistatⓇ, iAluRilⓇ and HyacystⓇ. Assays were then performed to examine the effect of the exogenous GAGs on cell viability, cell migration, sGAG production, cytokine and gene expression. Results All GAG formulations were well tolerated by the HTB-4 cells and supported cell growth and migration. iAluRilⓇ was most effective at stimulating endogenous sGAG production under all conditions, increasing sGAGs by up to 15-fold. All GAG formulations significantly reduced the production of the pro-inflammatory cytokine IL-8 under basal conditions, while no GAG treatment suppressed cytokine production under any other condition. Only CystistatⓇ had a significant effect on HA receptor expression, significantly increasing ICAM-1 expression at 3 h that returned to basal levels at 24 h. No GAG treatment significantly changed the expression of GAG synthesis enzymes (CSGALNACT1, CSGALNACT2) or markers of tissue remodeling (MMP2, TIMP1) and pain (COX-1/PTGS-1, NGF). Conclusions The data presented in this study reveal that commercial intravesical formulation support cell viability and migration. In addition, the commercial GAG formulations have a mild anti-inflammatory effect in the in vitro model of interstitial cystitis/bladder pain syndrome.Background Influx of innovative therapies and dramatic rise in prices have been prompting value-driven decision-making. Both the American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO) have independently proposed value assessment frameworks. Objectives To comprehensively examine the value of nivolumab and pembrolizumab by two value assessment frameworks with a cohort of published randomized controlled trials and offer insight into the association between these two frameworks. Methods Trials were identified with a cutoff date of Nov 30th, 2019. PROTAC tubulin-Degrader-1 Receiver operating characteristic curves were generated to establish the predictive value of ASCO-VF score to meet ESMO-MCBS grade and discriminate the agreement of these two value assessment tools. Spearman correlation was used to assess the association between monthly cost and ASCO-VF score/ESMO-MCBS grade. Results 19 randomized controlled trials were eligible. seven (36.8%) trials were of treatment included nivolumab while 12 (63.2%) pembrolizumab. 8 (42.1%) of the trials were of treatments for non-small-cell lung cancer, 5 (26.3%) for melanoma, 2 (10.5%) were for head and neck squamous cell carcinoma, 2 (10.5%) for gastric or gastro-oesophageal junction cancer and 1 (5.3%) for urothelial cancer and renal-cell carcinoma respectively. ASCO scores ranged from 7 to 94.7 with median 40.90. 11 (57.9%) trials met the ESMO criteria for meaningful value achieved. Of 14 trials not meeting the ASCO cutoff score, only 8 did not meet the meaningful ESMO criteria. Agreement between these two frameworks thresholds was only fair (κ = 0.412, P＜0.05). A negative correlation was noted between increment monthly cost and value assessment results. Conclusion There is only fair correlation between ASCO and ESMO value assessment frameworks. Not all treatment with nivolumab and pembrolizumab meet valuable thresholds.Background No pharmacological treatment exists to prevent or stop the calcification process of aortic valves causing aortic stenosis. The aim of this study was to develop a robust model of induced calcification in whole aortic valve leaflets which could be suitable for studies of the basic mechanisms and for testing potentially inhibitory drugs. Methods Pig hearts were obtained from a commercial abattoir. The aortic valve leaflets were dissected free and randomized between experimental groups. Whole leaflets were cultured in individual wells. Two growth media were used for cultivation standard growth medium and an antimyofibroblastic growth medium. The latter was employed to inhibit contraction of the leaflet into a ball-like structure. Calcification was induced in the growth medium by supplementation with an osteogenic medium. Leaflets were cultivated for four weeks and medium was changed every third day. To block calcification, the inhibitor SNF472 (a formulation of the hexasodium salt of myo-inositol hexaphosphate hexasodium salt) was used at concentrations between 1 and 100 µM. After cultivation for four weeks the leaflets were snap frozen in liquid nitrogen and kept at -80 °C until blind assessment of the calcium amount in leaflets by inductively coupled plasma optical emission spectroscopy. For statistical analysis, a Kruskal-Wallis test with Dunn's post-test was applied. Results Osteodifferentiation with calcium accumulation was in principle absent when standard medium was used. However, when the antimyofibroblastic medium was used, a strong calcium accumulation was induced (p = 0.006 compared to controls), and this was blocked in a dose-dependent manner by the calcification inhibitor SNF472 (p = 0.008), with an EC50 of 3.3 µM. Conclusion A model of experimentally induced calcification in cultured whole leaflets from porcine aortic valves was developed. This model can be useful for studying the basic mechanisms of valve calcification and to test pharmacological approaches to inhibit calcification.Moringa oleifera Lam., a plant native to tropical forests of India, is characterized by its versatile application as a food additive and supplement therapy. Accumulating evidence shows that Moringa plays a critical role in immune-related diseases. In this review, we cover the history, constituents, edibility, and general medicinal value of Moringa. The effects of Moringa in treating immune disorders are discussed in detail. Moringa can not only eliminate pathogens, including bacteria, fungi, viruses, and parasites, but also inhibit chronic inflammation, such as asthma, ulcerative colitis, and metabolic diseases. Additionally, Moringa can attenuate physical and chemical irritation-induced immune disorders, such as metal intoxication, drug side effects, or even the adverse effect of food additives. Autoimmune diseases, like rheumatoid arthritis, atopic dermatitis, and multiple sclerosis, can also be inhibited by Moringa. Collectively, Moringa, with its multiple immune regulatory bioactivities and few side effects, has a marked potential to treat immune disorders.
