As a bridge between wearable electronics and their surrounding environment and users, sensors are core components of WIEs and determine the implementation of their many functions. Although the existing sensor technology has evolved to a very advanced level with the rapid progress of advanced materials and nanotechnology, most of them still need external power supply, like batteries, which could cause problems that are difficult to track, recycle, and miniaturize, as well as possible environmental pollution and health hazards. In the past decades, based upon piezoelectric, pyroelectric, and triboelectric effect, various kinds of nanogenerators (NGs) were proposed which are capable of responding to a variety of mechanical movements, such as breeze, body drive, muscle stretch, sound/ultrasound, noise, mechanical vibration, and blood flow, and they had been widely used as self-powered sensors and micro-nanoenergy and blue energy harvesters. This review focuses on the applications of self-powered generators as implantable and wearable sensors in health monitoring, biosensor, human-computer interaction, and other fields. The existing problems and future prospects are also discussed. Copyright © 2020 Zhe Li et al.Human visual acuity is anatomically determined by the retinal fovea. The ontogenetic development of the fovea can be seriously hindered by oculocutaneous albinism (OCA), which is characterized by a disorder of melanin synthesis. Although people of all ethnic backgrounds can be affected, no efficient treatments for OCA have been developed thus far, due partly to the lack of effective animal models. Rhesus macaques are genetically homologous to humans and, most importantly, exhibit structures of the macula and fovea that are similar to those of humans; thus, rhesus macaques present special advantages in the modeling and study of human macular and foveal diseases. In this study, we identified rhesus macaque models with clinical characteristics consistent with those of OCA patients according to observations of ocular behavior, fundus examination, and optical coherence tomography. Genomic sequencing revealed a biallelic p.L312I mutation in TYR and a homozygous p.S788L mutation in OCA2, both of which were further confirmed to affect melanin biosynthesis via in vitro assays. These rhesus macaque models of OCA will be useful animal resources for studying foveal development and for preclinical trials of new therapies for OCA.

For complex molecules, such as viruses or virus-like particles (VLPs), the timeline becomes even more cumbersome. Thus, in the early stages of development, transient production methods serve as a reasonable alternative to stable clone construction. In this work, an investigation of a polyethylenimine- (PEI-) based transfection method for the transient production of Chikungunya (Chik) VLPs, a vaccine candidate molecule, was undertaken. This effort focuses on tracking cell population responses during transfection, understanding how process changes affect these responses, and monitoring patterns in cell performance over the culture duration. Plasmid labeling and VLP staining were employed to comprehensively track cells via flow cytometry and to draw correlations between plasmid DNA (pDNA) uptake and the resulting VLP expression. The method detected high transfection efficiency (≥97%) in all samples tested and demonstrated the capability to track kinetics of plasmid-cell binding. Monastrol in vitro With varied transfection cell concentrations, the pDNA binding kinetics are altered and saturation binding is observed in the lowest cell concentration sample tested in less than 3 hours of incubation. Interestingly, in all samples, the flow cytometry analysis of relative pDNA amount versus VLP expression staining showed that cells which contained fewer pDNA complexes resulted in the highest levels of VLP stain. Finally, to determine the potential breadth of our observations, we compared daily expression patterns of ChikVLP with a reporter, monomeric GFP molecule. The similarities detected suggest the interpretations presented here to likely be more broadly informative and applicable to PEI-based transient production of additional biological products as well.

The stem bark of the savanna tree Burkea africana (Hook) (family Leguminosae) is used in the Ghanaian traditional medicine for the management of various pain-related diseases. Objective This study seeks to investigate the possible antiallodynic and antihyperalgesic effects of the hydroethanolic stem bark extract of B. africana in a vincristine-induced peripheral neuropathy model in rats. Materials and Methods. 0.1 mg kg-1 vincristine was administered intraperitoneally for 5 days followed by 2 days break and continued for another 5 days to establish peripheral neuropathy in Sprague Dawley rats. Effects of Burkea africana (Hook) (family Leguminosae) is used in the Ghanaian traditional medicine for the management of various pain-related diseases. p.o.) and pregabalin (10-100 mg kg-1, i.p.) were assessed on tactile, intermediate, mechanical, cold, and hot allodynia as well as in the Randall-Sellito test. Moreover, the levels of total proteins, malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) in sciatic nerve tissue homogenates were assayed. Results BAE (50-1000 mg kg-1 p.o.) showed significant antiallodynic and antihyperalgesic effects similar to pregabalin by increasing paw withdrawal latency and paw withdrawal threshold in all the behavioral tests used. Also, the extract decreased the levels of MDA (a lipid peroxidation product) as well as MPO and caused a significant increase in endogenous antioxidants (GSH) and antioxidant enzymes (SOD and CAT) in tissue homogenates of treated rats. Conclusions Results from this study indicate that the hydroethanolic stem bark extract of B. africana exhibits antiallodynic and antihyperalgesic effects in vincristine-induced peripheral neuropathy in rats.B. africana in a vincristine-induced peripheral neuropathy model in rats.
