Medicinal Research Reviews, EarlyView.ABSTRACT Photoremovable protecting groups (PPGs) offer a straightforward solution for the temporary inactivation of biologically active substrates and their subsequent controlled release by light irradiation. Their relatively easy design and mode of application have made them useful tools for studying dynamic biological processes in vitro and in vivo ...

Synthesis and Characterization of MnO2 nanoparticles mediated by Raphia hookeri seed
Journal of Nigerian Society of Physical SciencesIn this study, managanese dioxide nanoparticles (MnO2-NP) was synthesized. Raphia hookeri seed was used as a bioreductant for the synthesis of MnO2-NPs. The biosynthesized MnO2-NPs was investigated for their reaction, structure and morphology.

Investigation of in vivo measurement of cerebral cytochrome-c-oxidase redox changes using near-infrared spectroscopy in patients with orthostatic hypotension [PDF]
, 2007 We have previously used a continuous four wavelength near infrared spectrometer to measure changes in the cerebral concentrations of oxy- (Δ[HbO2] and deoxy- haemoglobin (Δ[HHb]) during head-up tilt in patients with primary autonomic failure.

Nano Select, EarlyView.The graphical abstract represents fish scales, a waste by product, were repurposed as a bio‐adsorbent for Cr(III) and Co(II) removal. The scales were washed, dried, and ground before being tested under varying concentrations. FTIR analysis showed changes in functional groups after adsorption, while SEM revealed metal ion attachment.

Enhanced herbicidal activity of coumarin via carbon dot nanoformulation: synthesis and evaluation
Pest Management Science, EarlyView.We synthesized carbon nanocarriers from black wolfberry and combined them with coumarin to prepare coumarin‐loaded carbon dots (Cm‐CDs) nanocomplexes, which could significantly enhance the inhibitory effect of coumarin on weeds. Abstract BACKGROUND The integration of nanocarriers with biochemicals can markedly enhance the stability and efficacy of ...
