coli; Imhof and Schlötterer, 2001), the associated microbes are expected to adapt faster to changing environmental conditions than their hosts, due to their shorter generation times and their much greater population sizes (both relative to their hosts). The generation of genetic novelty might ...
Colonisation or infection with resistant pathogens may affect any group in society over lifetime, however vulnerability due to poverty may increase such risk. Socio-economic deprivation in housing, environment and work affects however the relationship between health and ill health from utero to older ...
This made Darwin realize that evolution must also have been gradual, otherwise organisms could not have remained adapted to their changing environments. A cactus finch in the Galapagos Islands, where Charles Darwin began to formulate his theory of evolution. Darwin observed that regions isolated ...
Over a time period of two years (November 2016 – November 2018), BVOC emissions of 10 bryophyte samples dominated bySymbiezidium transversalewere measured. Although the samples in this study are referred to by the dominant species, tropical forest bryophytes grow in communities of intermixed speci...
Due to its high reactivity, which rapidly attacks all relevant biomolecules (pigments, proteins, lipids, DNA), thus leading to serious deleterious effects [58], [59], the lifetime of 1ΔgO2 can be shortened down to 200 ns in cells [60]. Within this time span, the species can diffuse ...
Click reactions can be used to create complex polymer structures with precise control over their size and shape [55,57,58]. Polymer semiconductors have shown unique development advantages in the development of human-integrated electronic products due to their solution processability and mechanical ...
The calculated HI for the non-carcinogenic health was 0.27, less than 1, suggesting that the lifetime exposure to these elements may not result in chronic risk posing adverse health effects in Sri Lankan adults. Moreover, the EDI of NETs for Sri Lankan adults was 9.38 × 10−5± 1.58 ...
Likewise, symbiotic microorganisms can not only change their own phenotypic traits in response to environmental cues by the use of epigenetic mechanisms but also influence gene expression in the host by changing its epigenome. An example is the microbiome in the human colon that can modify the epig...
Compared with the intensity-based method, the lifetime-based detection is independent of the probe concentration and can efficiently distinguish the signals of the probe from the autofluorescence in complex biological samples. In addition, iridium Ir1 in the detection material is often used as ...
However, there is undergoing work in improving their use with promising results, and it is predicted that with improvements in sensing technology, it may be possible that a robot could carry a lifetime supply of chemicals [21]. The use of olfactory sensors in robotics is a developing area ...
