4% vs. 20.1%, P=0.004; 47.4% vs. 22.1%, P=0.020; invasive mechanical ventilation 47.4% vs.13.2%, P<0.001; 47.4% vs. 17.7%, P=0.004). Furthermore, 60-day all-cause mortality attributed to Flu/RSV coinfections was significantly greater than that for Flu and RSV mono-infected patients (36.8% vs. 8.0%,P<0.001; 36.8% vs. 11.5%, P=0.004.

The findings of this study suggest that coinfection of Flu/RSV in adults is associated with a high adverse outcome. Thus, Flu/RSV coinfections should be increasingly appreciated and given appropriate management.

Despite being a promising technology, problems such as operational barriers, complex reaction mechanisms and scaling have to be solved to make it a commercial technology. To bridge this current gap, this review elaborates on the chemistry of the conversion of lignocellulosic biomass. Besides, a comprehensive overview of the influence of the HTC operational conditions (pH, temperature, waterbiomass ratio, residence time and water recirculation) are discussed to better understand how hydrochar with desired properties can be efficiently produced. selleckchem Large-scale examples of the application of HTC are also presented. Current applications of hydrochar in the fields of energy, biocatalysis and environment are reviewed. Finally, economic cost and future prospects are analyzed.Molybdenum disulfide nanoparticles (MoS2 NPs) hold tremendous properties in wide domain of applications. In this study, the impact of MoS2 NPs was investigated on algal physiological and metabolic properties and a two-stage strategy was acquired to enhance the commercial potential of Dunaliella salina. With 50 µg/L of MoS2 NPs exposure, cellular growth and biomass production were promoted by 1.47- and 1.33-fold than that in control, respectively. MoS2 NPs treated cells were subject to high light intensity for 7 days after 30 days of normal light cultivation, which showed that high light intensity gradually increased β-carotene content by 1.48-fold. Furthermore, analyses of primary metabolites showed that combinatorial approach significantly altered the biochemical composition of D. salina. Together, these findings demonstrated that MoS2 NPs at an optimum concentration combined with high light intensity could be a promising approach to concurrently enhance biomass and β-carotene production in microalgae.Water supply around the globe is struggling to meet the rapidly increasing demand by the population, drastic changes in climate and degrading water quality. Even though, many large-scale methods are employed for wastewater treatment they display several negative impacts owing to the presence of pollutants. Technological innovation is required for integrated water management with different groups of nanomaterials for the removal of toxic metal ions, microbial disease, organic and inorganic solutes. The method of manipulating atoms on a nanoscale is nanotechnology. Nanomembranes are used in nanotechnology to soften water and eliminate physical, chemical and biological pollutants. The present review concentrates on various nanotechnological approaches in wastewater remedy, mechanisms involved to promote implementation, benefits and limitations in comparison with current processes, properties, barriers and commercialization research needs. Also the review identifies opportunities for further exploiting the exclusive features for green water management by following the advances in nanotechnology.The use of effluents for hydrogen production through dark fermentation is promising because it results in the generation of value-added products and reduction of the effluent's organic load. A low-cost medium using agroindustrial effluents, corn steep liquor (CSL) and cassava processing wastewater (CPW) was evaluated for hydrogen production with microbial consortia (Vir and Gal). Four variables were evaluated for their impact on biohydrogen production through a Plackett Burman design. Subsequently, the significant variables were optimized using a central composite design, resulting in two mathematical models with regression coefficients R2 > 0.92. The maximum yields were validated and resulted in 107 and 83.1 mL of biohydrogen/g COD removed for Vir and Gal, respectively. The lower medium cost for biohydrogen production was 81.5 USD/m3, approximately 80% more economical than some supplemented media. Finally, the scale-up of the biohydrogen production by consortia to 5L resulted in an increase of more than 40%.Fast partial hydropyrolysis of biomass was carried out at the level with hydrogen concentration of 0% to 30% and temperatures ranging from 700 to 900 °C by using a downer pyrolyzer. A theoretical parametric effect on yields and properties of the hydropyrolysis products were clarified. It was found that the volatile matter evolved during pyrolysis was substantially increased in the presence of hydrogen. The yields of CH4, C2H6 and light tar increased with increasing elevated H2 ratio, CH4 showed an especially large yield increase. The produced methane mainly comes from the reactions of hydropyrolysis of biomass and secondary hydrogenation of tar. Moreover, the presence of alkali and alkaline earth metals matters was significant catalyzes on both reactions. The CH4 yield increased with elevating the operating temperature and optimal sweeping-gas flow rate is 150 mL/min. These results will be strengthening regulation of feedstocks-operating-products in the practical Biomass Fast Partial Hydropyrolysis technology.Short chain carboxylic acids (SCCAs) have attracted much attention due to their wide application and benefit of high economy. This study investigated the influence of organic load rates (OLRs) on short-chain carboxylic acids (SCCAs) production and microbial communities for co-digestion of swine manure (SM) and corn silage (CS) during four different OLRs stages in a semi-continuous mode. The results showed that relatively stable SCCAs concentration of 10.5-13.6 g COD/L and SCCAs yield of 0.42 mg COD/mg VS was achieved at OLR of 3.0 g VS/L·d. The maximum concentration of 19.1 g COD/L was achieved at 3.5 g VS/L·d. Volatile fatty acids (VFAs) (include acetic, n-butyric and caproic acids) accounted for approximately 80% of SCCAs. Hydrolysis bacteria (HB) including Clostridium, Terriporobacter, Intestinibacter, and Turiibacter decreased with the increase of OLR, while acidogenic bacteria (AB) including Acetobacter, Lactobacillus, Aeriscardovia, and Pseudomonas increased, resulting in insufficient degradation of CS.
