This research is focused on synthesis of Cu-TiO2 nanoparticles (NPs) by bio-mediated method using Phoenix dactylifera fruit extract. The lignocellulosic entities of P. dactylifera fruit extract used as reducing and capping agent due to presence of higher contents of phenolics and flavonoids. These synthesized NPs are characterized by ultraviolet-visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy. Cu-TiO2 NPs synthesized by bio-mediated method are cost effective and environmental friendly. Results showed the average size of NPs was found to be 32.07 nm. Furthermore, these NPs act as very effective and suitable nano-catalyst for dyes degradation and reduces the concentration of Rhodamine-B to 89.8% and methyl orange to 95.3% dyes in wastewater. Results revealed that the synthesized NPs could possibly be employed for degradation of other toxic pollutants particularly dyes. [ABSTRACT FROM AUTHOR]

• Non-O Blood group had an increased association with ischemic stroke (IS), myocardial infarction (MI), and peripheral vascular disease (PVD). • Blood groups A and AB had the strongest association to IS, MI and PVD. • ABO blood groups have been associated with the pathophysiology of cardiovascular diseases through an influence on two important blood clotting proteins, von Willebrand factor and factor FVIII levels. Cardiovascular illnesses have been associated to ABO blood types, specifically through an effect on von Willebrand factor and factor FVIII levels. We conducted a meta-analysis to comprehensively explore the relationship between blood groups and ischemic stroke, myocardial infarction, and peripheral vascular disease. A comprehensive meta-analysis was undertaken to investigate blood groups and ischemic stroke (IS), myocardial infarction (MI) and peripheral vascular disease (PVD). Odds ratios (OR) were used to assess the relationship between blood groups and disease. RevMan v5,4 was used to statistically analyse the results. Risk of bias was assessed using the Newcastle-Ottawa scale. A total of 72 studies (18 ischemic stroke, 37 myocardial infarction, 17 peripheral vascular disease) met our search criteria, totalling 145,499 cases and 2,113,736 controls. Mean age ranged between 18 and 90 years. Compared to blood group-O, non-O blood group had an increased association with IS (OR=1.13, 95%Cl: 1.07-1.21, P < 0.001), MI (OR=1.17, 95%Cl: 1.11-1.24, P < 0.001) and PVD (OR=1.15, 95%Cl: 1.04-1.28, P =0.005). Compared to blood group-O, blood group A had a stronger statistically significant association to IS (OR=1.19, P =0.001), MI (OR=1.22, P < 0.001) and PVD (OR=1.15, P =0.03). Blood group-B has the lowest risk associated with MI (OR=1.09, P =0.01). In addition, blood groups AB had a stronger statistically significant association to IS (OR=1.24, P =0.01), and MI (OR=1.20, P < 0.001) compared with the other blood groups. Compared to blood group-O, groups A and AB are strongly associated to ischemic stroke, myocardial infarction, and peripheral vascular disease. [ABSTRACT FROM AUTHOR]

Incorporation of inorganic and organic materials in polymer has contributed well towards the development of advanced reverse-osmosis membranes; with greater permeation, and salt rejection potential. We are reporting, Zeolite/GO/PVDF based thin-film composite membranes that were successfully synthesized by solution casting process, an eco-friendly, low-cost, and biocompatible technique. PVDF membranes modified with different ratios of GO/Zeo (0.03, 0.05 and 0.07) were characterized by FTIR, SEM, XRD, TGA, and DSC. Membranes were then tested for its potential for water permeation and salt rejection abilities. As prepared membranes owe better pore-distribution, a moderate degree of crystallinity and high absorption capability that is highly needed for micro-filtration phenomena used for desalination of saline water. The modified membranes exhibited enhanced water permeability up to 28.9 L/m2h as compared to pure PVDF membrane having water permeability flux of 15.6 L/m2h. Salt-rejection ability was found increasing for the membranes (up to 98%) modified with different concentration of GO/Zeo, as compare to pure PVDF membrane (82%). During water permeation and salt rejection studies, no deleterious impact was noted for modified PVDF membranes. This development will entail an efficient approach to furnish high-level performance reverse-osmosis membranes, with greater osmotic-pressure bearing capacity and higher stability. [Display omitted] • Polyvinylidene fluoride membranes with enhanced properties have been prepared. • Properties have been enhanced by adding GO and Zeolite nanofillers. • Membranes have been characterized using FTIR, SEM, XRD and TGA techniques. • The membranes exhibited excellent desalination potential.

The aim of this work was to investigate the impact of nano selenium (N–Se) and compost on the growth, photosynthesis, enzymes activity, compatible solutes and metals accumulation in soybean grown under tannery effluent polluted soil. The plants were exposed to compost application (no compost and compost addition) and foliar application of N–Se (0, 25, 50, and 75 mg L−1). The results showed the addition of compost in soil and foliar applied N–Se alleviated the toxic effect of tannery effluent polluted soil. Furthermore, foliar application of N–Se with basal compost supply significantly improved antoxidant enzymes activity in soybean grown in tannery effluent polluted soil. Addition of compost increased the root dry weight (46.43%) and shoot dry weight (33.50 %), relative water contents by (13.74 %), soluble sugars (15.99 %), stomatal conductance (gs) (83.33 %), intercellular CO 2 concentration (Ci) (23.34 %), transpiration rate (E) (12.10 %) and decreased the electrolyte leakage (27.96 %) and proline contents by (20.34 %). The foliage application of N–Se at the rate of 75 mg L−1 showed the most promising results in control and compost amended tannery effluent polluted soil. The determined health risk index (HRI) values were recorded less than 1 for both adults and children under the application of compost and N–Se. In summary, the combined use of N–Se at 75 mg L⁻1 and basal supply of compost is an effective strategy for enhancing soybean productivity while minimizing the potential risks of metal accumulation in soybean grains grown in tannery effluent polluted soil. [Display omitted] • N–Se and compost enhance plant resilience in polluted environments. • Synergistic effect of N–Se and compost enhance growth, antioxidative defenses and osmolyte accumulation in soyabean. • It is viable approach for reducing metal contamination which would further reduce the HRI.
