AbstractG-quadruplexes (G4s) are four-stranded nucleic acid structures with closely spaced guanine bases forming square planar G-quartets. Aberrant formation of G4 structures has been associated with genomic instability. However, most plant species are lacking comprehensive studies of G4 motifs. In this study, genome-wide identification of G4 motifs in barley was performed, followed by a comparison of genomic distribution and molecular functions to other monocot species, such as wheat, maize, and rice. Similar to the reports on human and some plants like wheat, G4 motifs peaked around the 5′ untranslated region (5′ UTR), the first coding domain sequence, and the first intron start sites on antisense strands. Our comparative analyses in human, Arabidopsis, maize, rice, and sorghum demonstrated that the peak points could be erroneously merged into a single peak when large window sizes are used. We also showed that the G4 distributions around genic regions are relatively similar in the species studied, except in the case of Arabidopsis. G4 containing genes in monocots showed conserved molecular functions for transcription initiation and hydrolase activity. Additionally, we provided examples of imperfect G4 motifs.

Fabric Comfort

The problem of the transmission mechanism of textile perception and the barrier to express textile cognition directly are the two major issues in the field of textile evaluation. In this study, an advanced biomedical imaging technology, functional magnetic resonance imaging, which is non-invasive and has a high temporal resolution and spatial resolution, was utilized to describe the features of brain perception in the brain mask areas under increased fabric contact pressures, and thus it was attempted to provide a new approach to express fabric comfort perception. As a result, we found that when fabric contact pressure increased from 0.5 to 1.5 kPa, both maximum activation intensity T Z and activation proportion K of the peak points were transferred from the postcentral gyrus in the SI to the amygdala, and were negative activations. Therefore, we drew the conclusion that both a lower and a higher fabric contact pressure (about 1 kPa of proper comfort fabric pressure) would produce a brain signal inhibitory effect on the SI and amygdala. The difference was the fact that the inhibition role on the SI was more obvious under a lower pressure, while the inhibition role on the amygdala was more remarkable under a higher pressure, which meant that the SI, particularly the postcentral gyrus in the SI, was likely to play a significant role in surface tactile perception of fabrics, while the amygdala might be related to the fabric oppressing sensation.

The presence of heavy metals in industrial wastewater needed to be removed in other to control pollution which has been caused as a result of human and industrial activities. Several adsorbents have been used for the remediation process but with this particular research work, Zeolites were used. They were synthesized hydrothermally from various locally available raw materials namely rice husk, corn stalk, corn husk, and kaolin. They were characterized using their FTIR to determine the functional groups on the material synthesized and also their adsorptive activities were compared with industrially synthesized Zeolite X. A very strong peak at 1052 cm-1 is as a result of the asymmetric vibrations of the internal T-O tetrahedron with a weak symmetric T-O stretching vibration recorded at 797 cm-1. Another strong peak was observed at 445 cm-1 as a result of the O-T-O bending vibration which confirms the presence of a five-membered structure. The adsorptive properties of the synthesized Zeolites were evaluated by using them to remove Cadmium ions from solution and their percentage removals were determined. Similarly, their adsorption kinetics were also determined and was observed the R2 values to be 0.9093 and 0.9454 for Corn husk and Cornstalk for the first order and the second order with R2 values of 1 for rice husk, kaolin and corn stalk.
