Bayoumi, Mahitab;Arafa, Mona G.;Nasr, Maha;Sammour, Omaima A. research published 《 Nobiletin-loaded composite penetration enhancer vesicles restore the normal miRNA expression and the chief defence antioxidant levels in skin cancer》, the research content is summarized as follows. Skin cancer is one of the most dangerous diseases, leading to massive losses and high death rates worldwide. Topical delivery of nutraceuticals is considered a suitable approach for efficient and safe treatment of skin cancer. Nobiletin; a flavone occurring in citrus fruits has been reported to inhibit proliferation of carcinogenesis since 1990s, is a promising candidate in this regard. Nobiletin was loaded in various vesicular systems to improve its cytotoxicity against skin cancer. Vesicles were prepared using the thin film hydration method, and characterized for particle size, zeta potential, entrapment efficiency, TEM, ex-vivo skin deposition and phys. stability. Nobiletin-loaded composite penetration enhancer vesicles (PEVs) and composite transfersomes exhibited particle size 126.70 ± 11.80 nm, 110.10 ± 0.90 nm, zeta potential + 6.10 ± 0.40 mV, + 9.80± 2.60 mV, entrapment efficiency 93.50% ±3.60, 95.60% ± 1.50 and total skin deposition 95.30% ± 3.40, 100.00% ± 2.80, resp. These formulations were selected for cytotoxicity study on epidermoid carcinoma cell line (A431). Nobiletin-loaded composite PEVs displayed the lowest IC₅₀ value, thus was selected for the in vivo study, where it restored skin condition in DMBA induced skin carcinogenesis mice, as delineated by histol. and immuno-histochem. anal., biochem. assessment of skin oxidative stress biomarkers, in addition to miRNA21 and miRNA29A. The outcomes confirmed that nobiletin- loaded composite PEVs is an efficient delivery system combating skin cancer.

Bayati, Mohamed;Vu, Danh C.;Vo, Phuc H.;Rogers, Elizabeth;Park, Jihyun;Ho, Thi L.;Davis, Alexandra N.;Gulseven, Zehra;Carlo, Gustavo;Palermo, Francisco;McElroy, Jane A.;Nagel, Susan C.;Lin, Chung-Ho research published 《 Health risk assessment of volatile organic compounds at daycare facilities》, the research content is summarized as follows. Children are particularly vulnerable to many classes of the volatile organic compounds (VOCs) detected in indoor environments. The neg. health impacts associated with chronic and acute exposures of the VOCs might lead to health issues such as genetic damage, cancer, and disorder of nervous systems. In this study, 40 VOCs including aldehydes and ketones, aliphatic hydrocarbons, esters, aromatic hydrocarbons, cyclic terpenes, alcs., and glycol ethers were identified and qualified in different locations at the University of Missouri (MU) Child Development Laboratory (CDL) in Columbia, Missouri. Our results suggested that the concentrations of the VOCs varied significantly among classrooms, hallways, and playground. The VOCs emitted from personal care and cleaning products had the highest indoor levels (2-ethylhexanol-1, 3-carene, homomenthyl salicylate with mean concentration of 5.15 μg/m³, 1.57 μg/m³, and 1.47 μg/m³, resp.). A cancer risk assessment was conducted, and none of the 95th percentile dose estimates exceeded the age-specific no significant risk levels (NSRL) in all classrooms. Dimensionless toxicity index scores were calculated for all VOCs using a novel web-based framework called Toxicol. Prioritization Index (ToxPi), which integrates multiple sources of toxicity data. According to the method, homomenthyl salicylate, benzothiazole, 2-ethylhexyl salicylate, hexadecane, and tridecane exhibited diverse toxicity profiles and ranked as the five most toxic indoor VOCs. The findings of this study provide critical information for policy makers and early education professionals to mitigate the potentially neg. health impacts of indoor VOCs in the childcare facilities.

Several studies have highlighted the dependency of PTEN deficient tumors to PI3Kβ activity and specific inhibition of PI3Kδ has been shown activity against human B-cell cancers. We describe the discovery and optimization of a series of 8-(1-anilino)ethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamides as PI3Kβ/δ inhibitors, which led to the discovery of the clin. candidate 13, also known as AZD8186. On the basis of the lower lipophilicity of the chromen-4-one core compared to the previously utilized pyrido[1,2-a]pyrimid-4-one core, this series of compounds displayed high metabolic stability and suitable phys. properties for oral administration. Compound 13 showed profound pharmacodynamic modulation of p-Akt in PTEN-deficient PC3 prostate tumor bearing mice after oral administration and showed complete inhibition of tumor growth in the mouse PTEN-deficient PC3 prostate tumor xenograft model. 13 Was selected as a clin. candidate for treatment of PTEN-deficient cancers and has recently entered phase I clin. trials.

Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Recommanded Product: Diethylene Glycol Monoethyl Ether.

Bagheri, Hamidreza;Karimi, Nima;Dan, Sasan;Notej, Behrouz;Ghader, Sattar research published 《 Ionic liquid excess molar volume prediction: A conceptual comparison》, the research content is summarized as follows. In this study, the prediction of excess molar volume of ionic liquid + solvent binary system is described using modified two-parameter and three-parameter cubic equation of state (CEoS). The studied binary systems are consisted of 41 ionic liquids, 40 solvents and 5293 data point in the wide temperature range (278.15-353.15 K), ionic liquid mole fraction (0.0036-0.9920) and atm. pressure i.e. P = 1 bar. At the first step, the volume-translated parameter (c) was obtained based on three linear, distance function and exponential-type temperature-dependent cases and using exptl. pure d. After that, and due to easy-to-use of c-parameter, various formula was presented based on pure component thermodn. features for all three cases (IL and solvent, sep.). Finally, to investigate the accuracy of presented c-parameter formula, the excess molar volume of 119 various binary systems was molded using volume-translated PR (VTPR) EoS and volume-translated SRK (VTSRK) EoS without using any binary interaction parameter and the obtained results was compared with the original three-parameter CEoS, Patel-Teja (PT) EoS. The obtained results indicated that the performed two-parameter CEoS modification leads to increase the accuracy of the conventional PR EoS and SRK EoS in comparision to original two-parameter CEoS version and also, PT EoS. The average absolute percent deviation of the VTSRK EoS (c-parameter based on distance function) and the VTPR EoS (c-parameter based on exponential-type temperature-dependent volume-translated) were fewer values through all studied cases and it was 2.0443 and 2.8927, resp.

Tryptophan hydroxylase 1 (TPH1) has been recently suggested as a promising therapeutic target for treating obesity and fatty liver disease. A new series of 1,2,4-oxadiazolylphenyl alanine derivatives were identified as TPH1 inhibitors. Among them, compound 23a was the most active in vitro, with an IC₅₀ (half-maximal inhibitory concentration) value of 42 nM, showed good liver microsomal stability, and showed no significant inhibition of CYP and hERG. Compound 23a inhibited TPH1 in the peripheral tissue with limited BBB penetration. In high-fat diet-fed mice, 23a reduced body weight gain, body fat, and hepatic lipid accumulation. Also, 23a improved glucose intolerance and energy expenditure. Taken together, compound 23a shows promise as a therapeutic agent for the treatment of obesity and fatty liver diseases.
