Learning space for children with different sensory needs, nowadays, can be interactive, multisensory experiences, designed collaboratively by 1) specialists in special-needs learning, 2) extended realities (XR) technologists, and 3) sensorial diverse children, to provide the motivation, challenge, and development of key skills. While traditional audio and visual sensors in XR are challenging for XR applications to meet the needs of visually and hearing impaired sensorial-diverse children, our research goes a step ahead by integrating sensory technologies including haptic, tactile, kinaesthetic, and olfactory feedback that was well received by the children. Our research also demonstrates the protocols for 1) development of a suite of XR-applications; 2) methods for experiments and evaluation; and 3) tangible improvements in XR learning experience.

Diethylmaleate, D,L-buthionine-[S,R]-sulfoximine, and patulin induced an unexpected decrease in the susceptibility of resistant eggs to thiabendazole, which was chosen as a reference for resistance to benzimidazole compounds. The results demonstrate that the level of GSH or SH analog plays an important role in the toxicity of thiabendazole to nematode eggs.

This method was adapted from assays developed for the study of similar mechanisms in tumor cells. Rhodamine 123, a P-glycoprotein transport probe, associated with the reversal agent verapamil gave a significantly higher level of green fluorescence in Haemonchus contortus-resistant eggs as compared with that of susceptible eggs.

View Article and Find Full Text PDFFlow cytometry technique was applied to normal pig chromosomes and to three different reciprocal translocations: trcp (4q-; 14p), trcp (3p+;7q-) and trcp (1q-;15q+). The rearranged chromosomes generate new peaks which seem to correspond to their relative lengths. Therefore, it is necessary to confirm these results by banding analysis and/or by hybridization on these chromosomes with probes of genes known to be localized on them.
