    A formulation of an adapalene nanohydrogel (ADP-NH) using different surfactants and cosurfactants for topical application was developed and characterized. The best formulation was obtained with nanohydrogel (NH) containing Tween-80- (NH-Tween-80-) incorporated carbopol-940 and ethanol, 0.67% and 3.00% w / w , respectively. The optimized formulations of NH-Tween-80, nanohydrogel containing sodium lauryl sulphate (NH-SLS), and nanohydrogel containing glycerol (NH-glycerol) were separately evaluated to examine their in vitro and ex vivo permeability characteristics and compared with 0.3% dimethyl sulfoxide (control) solution. The polydispersity index of NH-Tween-80, NH-SLS, and NH-glycerol were found to be 0.264 ± 0.312 , 0.382 ± 0.0045 , and 0.310 ± 0.412 , respectively. All NH formulations showed pH within human skin pH ranges throughout the stability period. The NH-Tween-80 revealed 191.22 μg/mL of ADP permeation through Strat-M® membrane which was statistically significant ( p &lt; 0.05 ) compared to NH-SLS, NH-glycerol, and control solution. At 24 h, NH-Tween-80 demonstrated 305.11 μg/mL of ADP permeation in Wistar rat abdominal skin which was 1.99-, 1.56-, and 4.89-fold higher in comparison with NH-SLS, NH-glycerol, and control solution, respectively. Moreover, the ex vivo permeability of NH-Tween-80 was also compared with conventional gel (market sample) which was 3.38-fold greater at 24 h. During the 6th month of accelerated stability analysis, the NH-Tween-80, NH-SLS, and NH-glycerol demonstrated 99.25 % ± 0.15 , 91.23 % ± 0.41 , and 96.08 % ± 0.20 drug content, respectively. There were no noticeable physical changes observed up to 6 months for NH-Tween-80, while color change was observed in the 1st month and 3rd month of accelerated stability samples of NH-SLS and NH-glycerol, respectively. In this study, only NH-Tween-80 was considered both physically and chemically stable formulation. Therefore, it was concluded that the topical application of ADP-NH containing Tween-80 could be a very promising alternative for the treatment of acne vulgaris.</jats:p

    The biggest difficulty of humans cannot change or advance the quality of life is an unwillingness to change their errors and shortcomings and to repent from it. There is also willing to change but they do not change just because no action and do not really do it. There are also people who have already known that it is true, accurate, should be performed and corresponding to the norms, but still they live in sin and self-interest to ignore the interests of others. Even worse is evil (sin) is often covered in hypocrisy behind beautiful, sweet, gentle, and courteous words to make people mesmerized/hypnotized. In the case of real repentance, it should demand a match between words and actions. If there is repentance, there is a change and peace. Therefore, humans must sincerely repent and strive for it

    Anti-cancer effects and mechanism of actions of aspirin analogues in the treatment of glioma cancer

    INTRODUCTION: In the past 25 years only modest advancements in glioma treatment have been made, with patient prognosis and median survival time following diagnosis only increasing from 3 to 7 months. A substantial body of clinical and preclinical evidence has suggested a role for aspirin in the treatment of cancer with multiple mechanisms of action proposed including COX 2 inhibition, down regulation of EGFR expression, and NF-κB signaling affecting Bcl-2 expression. However, with serious side effects such as stroke and gastrointestinal bleeding, aspirin analogues with improved potency and side effect profiles are being developed. METHOD: Effects on cell viability following 24 hr incubation of four aspirin derivatives (PN508, 517, 526 and 529) were compared to cisplatin, aspirin and di-aspirin in four glioma cell lines (U87 MG, SVG P12, GOS – 3, and 1321N1), using the PrestoBlue assay, establishing IC50 and examining the time course of drug effects. RESULTS: All compounds were found to decrease cell viability in a concentration and time dependant manner. Significantly, the analogue PN517 (IC50 2mM) showed approximately a twofold increase in potency when compared to aspirin (3.7mM) and cisplatin (4.3mM) in U87 cells, with similar increased potency in SVG P12 cells. Other analogues demonstrated similar potency to aspirin and cisplatin. CONCLUSION: These results support the further development and characterization of novel NSAID derivatives for the treatment of glioma

    Epigenetic control of translation checkpoint and tumor progression via RUVBL1-EEF1A1 axis

    Epigenetic dysregulation is reported in multiple cancers including Ewing sarcoma (EwS). However, the epigenetic networks underlying the maintenance of oncogenic signaling and therapeutic response remain unclear. Using a series of epigenetics- and complex-focused CRISPR screens, RUVBL1, the ATPase component of NuA4 histone acetyltransferase complex, is identified to be essential for EwS tumor progression. Suppression of RUVBL1 leads to attenuated tumor growth, loss of histone H4 acetylation, and ablated MYC signaling. Mechanistically, RUVBL1 controls MYC chromatin binding and modulates the MYC-driven EEF1A1 expression and thus protein synthesis. High-density CRISPR gene body scan pinpoints the critical MYC interacting residue in RUVBL1. Finally, this study reveals the synergism between RUVBL1 suppression and pharmacological inhibition of MYC in EwS xenografts and patient-derived samples. These results indicate that the dynamic interplay between chromatin remodelers, oncogenic transcription factors, and protein translation machinery can provide novel opportunities for combination cancer therapy.</p

    Thiophene-Fused Tropones as Chemical Warfare Agent-Responsive Building Blocks

    We report the synthesis of dithienobenzotropone-based conjugated alternating copolymers by direct arylation polycondensation. Postpolymerization modification by hydride reduction yields cross-conjugated, reactive hydroxyl-containing copolymers that undergo phosphorylation and ionization upon exposure to the chemical warfare agent mimic diethylchlorophosphate (DCP). The resulting conjugated, cationic copolymer is highly colored and facilitates the spectroscopic and colorimetric detection of DCP in both solution and thin-film measurements.United States.

    Background: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings: Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42\ub74% vs 44\ub72%; absolute difference \u20131\ub769 [\u20139\ub758 to 6\ub711] p=0\ub767; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5\u20138] vs 6 [5\u20138] cm H2O; p=0\ub70011). ICU mortality was higher in MICs than in HICs (30\ub75% vs 19\ub79%; p=0\ub70004; adjusted effect 16\ub741% [95% CI 9\ub752\u201323\ub752]; p&lt;0\ub70001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0\ub780 [95% CI 0\ub775\u20130\ub786]; p&lt;0\ub70001). Interpretation: Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status.
