The relationship of a diet low in fibre with mortality has not been evaluated. This study aims to assess the burden of non-communicable chronic diseases (NCD) attributable to a diet low in fibre globally from 1990 to 2019.
All data were from the Global Burden of Disease (GBD) Study 2019, in which the mortality, disability-adjusted life-years (DALY) and years lived with disability (YLD) were estimated with Bayesian geospatial regression using data at global, regional and country level acquired from an extensively systematic review.
All data sourced from the GBD Study 2019.
All age groups for both sexes.
The age-standardised mortality rates (ASMR) declined in most GBD regions; however, in Southern sub-Saharan Africa, the ASMR increased from 4·07 (95 % uncertainty interval (UI) (2·08, 6·34)) to 4·60 (95 % UI (2·59, 6·90)), and in Central sub-Saharan Africa, the ASMR increased from 7·46 (95 % UI (3·64, 11·90)) to 9·34 (95 % UI (4·69, 15·25)). Uptrends were observed in the age-standardised YLD rates attributable to a diet low in fibre in a number of GBD regions. The burden caused by diabetes mellitus increased in Central Asia, Southern sub-Saharan Africa and Eastern Europe.
The burdens of disease attributable to a diet low in fibre in Southern sub-Saharan Africa and Central sub-Saharan Africa and the age-standardised YLD rates in a number of GBD regions increased from 1990 to 2019. Therefore, greater efforts are needed to reduce the disease burden caused by a diet low in fibre.
The levels of drought tolerance and nucleotide polymorphism at the CBF4 locus were examined in a world-wide sample of 17 core accessions of Arabidopsis thaliana. The results showed that different accessions exhibited considerable differences in adaptation to drought stress. Compared with Columbia accession, the frequency of nucleotide polymorphism at the CBF4 locus of 25av, 203av and 244av accessions, including single nucleotide polymorphism (SNP) and insertion/deletion (Indel), was high, on average 1 SNP per 35.8 bp and 1 Indel per 143 bp. No significance in all regions of Tajima's D test indicated that the neutral mutation hypothesis could explain the nucleotide polymorphism in this CBF4 gene region. The higher polymorphism was the result of purification selection. Nucleotide polymorphism in the non-coding region was three times higher than in the coding region. This might indicate a recent relaxation of selection pressures on the non-coding region of CBF4 gene. In the coding region of CBF4, SNP frequency was 1 SNP per 96.4 bp and one non-synonymous mutation was detected from 25av, 203av and 244av accessions: the amino acid variation gly↔val at position 205, caused by the nucleotide variation G↔T at position 1034 (corresponding to the nucleotide at position 19 696 of GenBank accession no. AB015478 as 1). Furthermore, four differential SNPs were discovered in haplotype 6 constituted by 203av, one of them located in the 3′ non-coding region (A↔C at position 1106) and the others in the 5′ non-coding region (A↔G, A↔C and G↔A at positions 27, 129 and 171, respectively). The drought tolerance assay indicated that accession 203av was the best at tolerating water deficiency. We propose that haplotype 6 is consistent with its drought tolerance.
Nanobelts are a group of materials that have a rectangle-like cross section with typical widths of several hundred nanometers, width-to-thickness ratios of 5 to 10, and lengths of hundreds of micron meters. In this paper, nanoindentations were made on individual ZnO, SnO2 nanobelts and (0001) bulk ZnO by using AFM and Hysitron Triboscope indenters. It was shown that the indentation size effect was still obvious for the indentation depth under 50 nm. It is also demonstrated that nanomaching is possible on nanobelt using AFM tip.
