Environment-friendly pigments based on AFeo_(3)(A=La,Pr,Nd,Sm,Gd,Tb,Y or Yb)with high nearinfrared(NIR)reflectance were synthesised by a coprecipitation method at 1200℃.The Rietveld refinement analysis showed single-phase orthorhombic perovskite for all *** pigments,which showed reddish hues,offered good colour stability after mixing these pigments in powder form with siloxane transparent paint and two different *** powderepaint mixtures produced with GdFeo_(3),TbFeo_(3) and YFeo_(3) pigments have the highest NIR solar reflectance,reaching values of R=50%.The temperature shielding studies conducted using TbFeo_(3) pigmentepaint mixture for a roof coating yielded a reduction of 3.2℃ in comparison to a commercial ***,the glazes that were pigmented using GdFeo_(3),TbFeo_(3) and YFeo_(3) compositions also presented the most intense reddish colours.A study of the thermal and chemical stability of the pigment with the highest NIR solar reflectance showed good stability in both *** reddish pigments that were prepared can therefore be good candidates for use in different applications such as cool pigments or pigments for ceramic glazes at high temperatures.

To investigate the possible predictive role of routinely used glycemic parameters for a first venous thromboembolism (VTE) episode in gastrointestinal (GI) cancer ambulatory patients - with or without clinically diagnosed type 2 diabetes (T2D) or obesity - treated with ***-treatment fasting blood glucose, insulin, glycated hemoglobin (HbA1c) and homeostasis model of risk assessment (HoMA) were retrospectively evaluated in a cohort study of 342 GI cancer patients. Surgery was performed in 142 (42%) patients with primary cancer, 30 (21%) and 112 (79%) of whom received neoadjuvant and adjuvant therapies, respectively. First-line chemotherapy was administered in 200 (58%) patients with metastatic disease. The study outcome was defined as the occurrence of a first symptomatic or asymptomatic VTE episode during active *** glucose tolerance (IGT) or T2D were diagnosed in 30% of GI cancer patients, while overweight/obesity had an incidence of 41%. VTE occurred in 9.4% of patients (7% of non-diabetic non-obese), especially in those with a high ECoG score (P = 0.025). No significant association was found between VTE incidence and T2D, obesity, different tumor types, metastatic disease, Khorana class of risk, or different anti-cancer drugs, although VTE rates were substantially higher in patients receiving bevacizumab (17% vs 8%, P = 0.044). Conversely, all glucose metabolic indexes were associated with increased VTE risk at RoC analysis. Multivariate Cox proportional analyses confirmed that HoMA index (HR = 4.13, 95%CI: 1.63-10.5) or fasting blood glucose (HR = 3.56, 95%CI: 1.51-8.39) were independent predictors of VTE occurrence during *** results here reported demonstrate that evaluating glucose metabolic asset may allow for VTE risk stratification in GI cancer, helping to identify chemotherapy-treated patients who might benefit from thromboprophylaxis. Further multicenter prospective studies involv
