Arsenic removal from waste water by ozone oxidation combined with ferric precipitation

The oxidation of As(III) to As(V) followed by precipitation and adsorption is thought to be the most effective process for removal of arsenic in industrial wastewater. In this work, the oxidation of As(III) to As(V) with ozone was carried out in an acidic solution. After oxidation, arsenic was removed by precipitation in an iron (III) sulfate system under ambient pressure at 90°C in acid. Batch experimental results show that ozone is quite effective in oxidizing As(III) at low pH. And more than 90% of 5g/l As(III) was removed from the acidic solution by precipitation with Fe2(SO4)3 in 7-8 hours

Genome-wide association analysis with selective genotyping identifies candidate loci for adult height at 8q21.13 and 15q22.33-q23 in Mongolians

We performed a genome-wide association study with 23,465 microsatellite markers to identify genes related to adult height. Selective genotyping was applied to extremely tall and extremely short individuals from the Khalkh-Mongolian population. Two loci, 8q21.13 and 15q22.33, which showed the strongest association with microsatellites were subjected to further analyses of SNPs in 782 tall and 773 short individuals. The most significant association was observed with SNP rs2220456 at 8q21.13 (P = 0.000016). In the LD block at 15q22.32, SNP rs8038652 located in intron 1 of IQCH was strongly associated (P = 0.0003), especially the AA genotype of the SNP under a recessive model was strongly associated with adult height (P = 0.000046)

Physical activity attenuates the effect of the FTO T/A polymorphism on obesity-related phenotypes in adult Russian males [РЕГУЛЯРНАЯ ФИЗИЧЕСКАЯ НАГРУЗКА СНИЖАЕТ ВЛИЯНИЕ А-АЛЛЕЛЯ ГЕНА FTO НА ПРЕДРАСПОЛОЖЕННОСТЬ К ОЖИРЕНИЮ В ГРУППЕ РУССКИХ МУЖЧИН]

Introduction. Although the effect of the fat mass and obesity-associated (FTO) gene on adiposity is well established, there is a lack of evidence whether physical activity (PA) modifies the effect of FTO variants on obesity in Russians. Therefore, the purpose of this study was to examine PA influences and interactive effects between FTO variants and PA on measures of adiposity in Russians. Materials and methods. 110 Russian males aged 22-52 years old were examined. Anthropometry: height and weight, waist and hip circumferences were taken. The whole-body impedance was measured on the right-hand side of the body using the bioimpedance meter ABC-01 'Medas' (SRC Medas, Russia) according to a conventional tetrapolar scheme at a frequency of 50 kHz. For each subject participating in the study, the genotype was determined by the polymorphic systems of the T/A (rs9939609) polymorphism of the FTO gene (Lytekh, Moscow). Results. Participants who did not engage in regular PA exhibited higher BMI, fat mass, HC, and WC with statistical significance (P ≤ 0.01). Although significant associations between the three FTO genotypes and adiposity measures were found in the sedentary group. There were no significant associations between FTO genotypes and obesity-related phenotypes in the PA group. Conclusion. Comparison of morphological parameters in carriers of alternative genotypes in two subgroups with different lifestyles makes it possible to conclude that the A allele determines a greater tendency to accumulate fat in cases where there is no regular physical activity. © 2019 South Ural State University - Institute of Sport, Tourism and Service.

Несмотря на то, что влияние жировой массы и связанного с ожирением гена FTO на набор веса хорошо изучено, по-прежнему недостаточно данных о том, меняет ли физическая активность воздействие вариантов гена FTO на избыточный вес у россиян. Таким образом, цель данного исследования - изучить влияние физической активности, а также воздействие вариантов гена FTO и физической активности на показатели ожирения у россиян. Материалы и методы. В исследовании приняли участие 110 мужчин из России в возрасте от 22 до 52 лет. Были получены следующие антропометрические данные: длина и масса тела, объем талии и бедер. Импеданс тела был измерен с правой стороны с использованием биоимпедансметра АВС-01 МЕДАСС (ООО НТЦ Медасс, Россия) на частоте 50 кГц в соответствии с традиционной тетраполярной схемой. У каждого участника исследования генотип определялся по полиморфным системам T/A (rs9939609) полиморфизма гена FTO (лаборатория Литех, Москва). Результаты. Участники исследования, не практиковавшие регулярную физическую нагрузку, продемонстрировали более высокие статистически значимые показатели ИМТ, жировой массы, объема талии и бедер (P ≤ 0,01). При этом в группе лиц, ведущих малоподвижный образ жизни, были установлены значительные корреляции между тремя генотипами гена FTO и показателями ожирения. Участники, практикующие регулярную физическую нагрузку, не продемонстрировали статистически значимых связей между генотипами гена FTO и связанными с ожирением фенотипами. Заключение. Сравнение морфологических параметров у носителей альтернативных генотипов из двух подгрупп, ведущих разный образ жизни, позволяет сделать вывод, что А-аллель определяет большую предрасположенность к накоплению жировой массы в отсутствие регулярной физической нагрузки

International Nosocomial Infection Control Consortium report, data summary of 50 countries for 2010-2015: Device-associated module

•We report INICC device-associated module data of 50 countries from 2010-2015.•We collected prospective data from 861,284 patients in 703 ICUs for 3,506,562 days.•DA-HAI rates and bacterial resistance were higher in the INICC ICUs than in CDC-NHSN's.•Device utilization ratio in the INICC ICUs was similar to CDC-NHSN's. Background: We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. Methods: During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days. Results: Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs. Conclusions: Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
