H-ZSM-5 nano-zeolites were synthesized by hydrothermal method using tetrapropylammonium hydroxide (TPAOH) as a template in the presence of various TPABr concentrations. The effect of different TPABr/TPAOH molar ratios was studied on the catalytic performance of dehydration of methanol to dimethyl ether (DME) in a fixed bed reactor under the same operating conditions (T=300°C, P=1 atm, and WHSV=...

D iabetic macular edema (DME) is the main cause of visual impairment in diabetic patients. The aim of the present study was to explore the differential proteomic pattern of the vitreous fluid from DME patients by means of proteomic analysis. For this purpose, we used fluorescence-based difference gel electrophoresis (DIGE). This technique provides accurate quantitative comparisons, and we furth...

The uranyl amide [{Li(DME)}(2)Cl][Li(DME)][UO(2)(NC(5)H(10))(3)](2) has been synthesised and structurally characterised. Its stability is attributed to the saturation of the uranyl coordination sphere by "ate" complex formation.

hydrogen was produced by steam reforming of dimethyl ether (dme) using a physical mixture of commercial hzsm-5 zeolite (for dme hydrolyzing) and cu/zno/al2o3 (for methanol steam reforming) as a catalyst in a fixed bed reactor. the experiments were performed at atmospheric pressure and in a temperature range from 270 to 310 °c. the effects of feed temperature and gas hourly space velocity (ghsv)...

BACKGROUND Findings of prior studies have been inconclusive about the ocular effects of thiazolidinediones on diabetic macular edema (DME). We evaluated, in patients with type 2 diabetes (T2D), the short-term and long-term risks of developing DME among users vs nonusers of thiazolidinediones. METHODS A retrospective cohort study of 103,368 patients with T2D and no DME at baseline using The He...

PURPOSE To assess the association of serum lipids with diabetic retinopathy (DR), diabetic macular edema (DME), and macular thickness in adults with diabetes. METHODS Diabetic patients aged ≥ 18 years were prospectively recruited from specialized eye clinics in Melbourne, Australia. Fasting total-C (cholesterol), triglyceride, HDL-C, non-HDL-C, and LDL-C were assessed. DR was graded from fund...

Diabetic macular edema (DME) can cause blindness in diabetic patients suffering from diabetic retinopathy (DR). DM parameters controls (glycemia, arterial tension, and lipids) are the gold standard for preventing DR and DME. Although the vascular endothelial growth factor (VEGF) is known to play a role in the development of DME, the pathological processes leading to the onset of this disease ar...
