Uticaj sistema gajenja u promenljivim vremenskim uslovima na prinos bosiljka

The effect of weather conditions, precipitations and mean daily air temperatures in the vegetation period 2012-2016 on the fresh mass yield of basil (Ocimum basilicum L.) in the organic and conventional production systems was investigated. Trials were carried out on chernozem at the experimental fields of the Institute of Field and Vegetable Crops located in Bački Petrovac. The highest yield in the first harvest was obtained in 2016, in the second in 2013, while the lowest yield was recorded in both harvests in 2012. Growing system is not affect the yield of the basil fresh mass, while the changeable weather conditions in different years had a significant or highly significant effect to the yield.Analiziran je uticaj vremenskih uslova, padavina i srednjih dnevnih temperatura vazduha u vegetacionom periodu 2012-2016. godine na prinos sirove mase bosiljka (Ocimum basilicum L.) koji je gajen u sistemu organske i konvencionalne proizvodnje. Ispitivanja su vršena na zemljištu tipa černozem, na eksperimentalnim poljima Instituta za ratarstvo i povrtarstvo u Bačkom Petrovcu. Najveći prinos u prvom otkosu ostvaren je 2016, u drugom 2013. godine, dok je najmanji prinos u oba otkosa postignut 2012. Sistem gajenja nije značajnije uticao na prinos sirove mase bosiljka, dok su promenljivi vremenski uslovi, odnosno različite godine imale značajan ili veoma značajan uticaj na prinos

Fitotoksični efekti hlorpirifosa na ponike ječma i krastavca

Under Directive 2008/105 / EC, chlorpyrifos is one of the priority water pollutants. Its presence is mainly detected by chemical methods, although bioindicators are gaining in importance. The effect of chlorpyrifos (0.05-10 µg L-1) was evaluated on germination energy -GE and germination -G, length, fresh and dry weight of roots and shoots of barley and cucumber seedlings. In the bioassay, chlorpyrifos applied at MAC rate (0.1 µg L-1) caused a significant inhibition of GE and G of barley and at 0.5 µg L-1 of cucumber seeds, compared to control. At 50 % MAC (0.05 1 µg L-1), length, fresh and dry weight of roots and shoots of both tested plants were significantly inhibited, while in treatments with 0.5 µg L-1 and higher rates, there was no formation of hypocotyl and epicotyl of barley, i.e. hypocotyl of cucumber seedlings.Prema Direktivi 2008/105/EC, hlorpirifos je jedan od prioritetnih polutanata voda. Njegovo prisustvo se uglavnom detektuje hemijskim analizama, iako su sve značajnije i metode koje uključuju bioindikatore. U radu je procenjen uticaj hlorpirifosa (0,05-10 µg L-1) na energiju klijanja -EK, klijavost -K, dužinu, svežu i suvu masu korena i izdanka ječma i krastavca, kao potencijalnih indikatora. Hlorpirifos je izazvao značajnu inhibiciju EK i K semena ječma u MDK količini (0,1 µg L-1), a kod semena krastavca u količini 0,5 µg L-1, u odnosu na kontrolu. U količni 50% manje od MDK (0,05 µg L-1), dužina, sveža i suva masa i korena i nadzemnog dela obe test biljke su bili značajno smanjeni, dok u tretmanima sa preko 0,5 µg L-1 hlopririfosa, formiranje hipokotila i epikotila kod ječma, odnosno hipokotila kod krastavca, je izostalo

Characterization of macrolide-resistant non-invasive pneumococci in the pre-vaccine era in Serbia

Numerous reports have confirmed that increased macrolide use in the treatment of respiratory tract infection has contributed to the emergence of antibiotic resistance worldwide. Studies have also shown that pneumococcal vaccine can reduce pneumococcal resistance. The aim of this study was to determine the prevalence of co-resistance to penicillin and other antibiotics in macrolide-resistant (MR) non-invasive pneumococcal isolates and to evaluate serotype distribution in resistant strains in the pre-vaccine era in Serbia. About 80% of MR isolates expressed the MLS phenotype with very high resistance to both erythromycin and clindamycin. A total of 132 (84.1%) MR isolates were multiresistant, i.e., they were resistant to erythromycin, penicillin, tetracycline, and trimethoprim–sulfamethoxazole. Among 157 MR pneumococci, 11 different serotypes were found. Four serotypes, 19F, 14, 6B, and 23F, accounted for 77.7% of all MR pneumococcal isolates. Among isolates with the cMLS phenotype, serotypes 19F and 14 were predominant, whereas serotype 6A was the most common among those with the M phenotype, followed by 14. In conclusion, co-resistance to macrolides and penicillin in our non-invasive pneumococcal isolates is high. The majority of tested strains (∼80%) belonged to the four serotypes (19F, 14, 6B, and 23F) that are included in all conjugate vaccine formulations

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: a pooled analysis of 2181 population-based studies with 65 million participants

Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks

Rising rural body-mass index is the main driver of the global obesity epidemic in adults

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.Peer reviewe
