| 1 | Synthesis of cation exchange resin-supported iron and magnesium oxides/hydroxides composite for nitrate removal in water显示文摘In this study,we reported on the concept and practical use of cation exchange resin(CER)for removing anions in water via pretreating the CER with metal salts.The cation exchange resinsupported iron and magnesium oxides/hydroxides composite(FeMg/CER)was synthesized and introduced as a new and potential adsorbent for selective removal of nitrate ion in the water environment.Characteristics of FeMg/CER were determined by techniques such as Fouriertransform infrared spectroscopy,scanning electron microscopy,and Xray diffraction.The results showed that FeMg/CER material had a high nitrate adsorption capacity of 200 mg NO_(3)^()·g^(1)with a fast equilibrium adsorption time of 30 min at pH 5.In addition,it had good durability of at least 10 times of regeneration,which could be applied to practical water and wastewater treatment. | Trung Thanh Nguyen Vu Anh Khoa Tran Le Ba Tran Phuoc Toan Phan Minh Tan Nguyen Long Giang Bach Surapol Padungthon Cong Khiem Ta Nhat Huy Nguyen | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 2 |
| 6 | Hypoallergenic formula with Lactobacillus rhamnosus GGfor babies with colic:A pilot study of recruitment,retention,and fecal biomarkers显示文摘AIM To investigate recruitment, retention, and estimatesfor effects of formula supplementation withLactobacillus rhamnosus GG (LGG) on inflammatorybiomarkers and fecal microbial community in infants withcolic.METHODS: A prospective, double-blind, placebocontrolledtrial was conducted in otherwise healthyinfants with colic. We screened 74 infants and randomizedand analyzed results in 20 infants [9 receivingLGG (LGG+) and 11 not receiving LGG (LGG-)]. LGG wasincorporated in the formula (Nutramigen?) (minimum of3 × 10^7 CFU/d) in the LGG+ group. Fecal microbiota andinflammatory biomarkers, including fecal calprotectin(FC), plasma cytokines, circulating regulatory T cells(Tregs), and crying + fussing time were analyzed todetermine optimal time points and effect sizes for alarger trial.RESULTS: Recruitment in this population was slow, withabout 66% of eligible infants willing to enroll; subjectretention was better (75%). These rates were influencedby parents' reluctance to volunteer their infant for aclinical trial and by their tendency to change formulas.The maximal difference of crying + fussing time wasobserved at day 14, comparing the 2 groups, with amean difference of -91 (95%CI: -76, 259) min (P = NS).FC showed no significant difference, but the optimaltime to determine a potential effect was at day 90 [witha mean difference of 121 (95%CI: -48, 291) μg/g stool],observing a lower level of FC in the LGG+ group. Thefecal microbial communities were chaotic, as determinedby Shannon's diversity index and not apparently influencedby the probiotic. No significant change wasobserved in plasma inflammatory cytokines or Tregs,comparing LGG+ to LGG- groups.CONCLUSION: Designing future colic trials involving aprobiotic-supplemented formula for infants in the UnitedStates will require consideration for difficult enrollment.Infants with colic have major variations in feal microbiotaand calprotectin, both of which improve with time, withoptimal time points for measurement at days 14 and 90after treatment. | Nicole Y Fatheree Yuying Liu Michael Ferris Melissa Van Arsdall Valarie McMurtry Marcela Zozaya Chunyan Cai Mohammad H Rahbar Manouchehr Hessabi Ta Vu Christine Wong Juleen Min Dat Q Tran Fernando Navarro Wallace Gleason Sara Gonzalez J Marc Rhoads | 2016 | World Journal of Gastrointestinal Pathophysiology2016，7，1： | 1 |
