Abstract
Four human volunteers given a 30 mg oral dose of nicardipine hydrochloride containing 40 microCi of the 14C-labelled material achieved peak plasma levels of compound-related radioactivity within one hour of dosing. Parent compound comprised only a minor fraction of the circulating radioactivity indicating rapid first-pass metabolism. Plasma radioactivity declined to background levels within 96 h and was excreted both in the urine and faeces. Urinary excretion was the favoured route comprising about 60% of the dosed radioactivity. Mean total recovered radioactivity amounted to 94.8%. Both 1,4-dihydropyridine and pyridine metabolites of nicardipine hydrochloride were excreted in the urine. The major urinary metabolites, comprising some 36% of the radioactivity excreted in the 0-8 h post-dose period, were the glucuronide conjugates of +/- 2-hydroxyethyl methyl-1,4-dihydro-2,6-dimethyl-4(m-nitrophenyl)-3,5-pyridine dicarboxylate and its pyridine from 2-hydroxyethyl methyl-2,6-dimethyl-4-(m-nitrophenyl)-3,5-pyridine dicarboxylate.

Abstract
Hydrogen bonding interactions between biological chromophores and their surrounding protein and solvent environment significantly affect the photochemical pathways of the chromophore and its biological function. A common first step in the dynamics of these systems is excited state proton transfer between the noncovalently bound molecules, which stabilizes the system against dissociation and principally alters relaxation pathways. Despite such fundamental importance, studying excited state proton transfer across a hydrogen bond has proven difficult, leaving uncertainties about the mechanism. Through time-resolved photoelectron imaging measurements, we demonstrate how the addition of a single hydrogen bond and the opening of an excited state proton transfer channel dramatically changes the outcome of a photochemical reaction, from rapid dissociation in the isolated chromophore to efficient stabilization and ground state recovery in the hydrogen bonded case, and uncover the mechanism of excited state proton transfer at a hydrogen bond, which follows sequential hydrogen and charge transfer processes.

Abstract
We are reporting that the Lugiato-Lefever equation describing the frequency comb generation in ring resonators with the localized pump and loss terms also describes the simultaneous nonlinear resonances leading to the multistability of nonlinear modes and coexisting solitons that are associated with the spectrally distinct frequency combs.

Abstract
This work entails deep red emitting EuIII based complexes with a variety of ternary β-diketonate ligands and 1,10-phenanthroline as the ancillary ligand in the system. The solid state structure and spectroscopic analysis has been outlaid in terms of photoluminescence and crystallography. A luminescence quantum efficiency of 50% was obtained for the [tris-(4,4,4-trifluoro-1-chlorophenyl-butanedione)mono-(1,10-phenanthroline)europium(iii)] complexes. Moreover, complexes [tris-(2,2,6,6-tetramethyl-heptanedione)mono-(1,10-phenanthroline) europium(iii)] and {[hexa-(benzyl carboxylic acid) bis-(1,10-phenanthroline)di-europium(iii)]-μ-[κ2-O,O'-(benzyl carboxylic acid)]2} were found to also have quantum yields of 9% and 28% with respective sensitization efficiencies of 85%, 15% and 58%. These results were articulated with crystallographic details pertaining to the nature of coordination and the effect of steric and electronic properties thereof which somewhat impacts the Eu-N bond distances. A symmetry correlation was drawn between the crystallographic data and the photoluminescence data.

Abstract
Vegetable-type soybean, also known as edamame, was recently introduced to South Africa. However, there is lack of information on its responses to drought. The aim of this study was to investigate the photosynthetic efficiency and carbohydrates responses of six edamame cultivars under drought stress. Photosynthetic efficiency parameters, including chlorophyll fluorescence and stomatal conductance, were determined using non-invasive methods, while pigments were quantified spectrophotometrically. Non-structural carbohydrates were quantified using Megazyme kits. Structural carbohydrates were determined using Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). Drought stress significantly increased the Fv/Fm and PIabs of AGS429 and UVE17 at pod filling stage. Chlorophyll-a, which was most sensitive to drought, was significantly reduced in AGS429 and UVE17, but chlorophyll-b was relatively stable in all cultivars, except UVE17, which showed a significant decline at flowering stage. AGS354 and AGS429 also showed reduced chlorophyll-b at pod filling. UVE17 showed a significant reduction in carotenoid content and a substantial reduction in stomatal conductance during pod filling. Drought stress during pod filling resulted in a significant increase in the contents of trehalose, sucrose and starch, but glucose was decreased. Chlorophyll-a positively correlated with starch. The FTIR and XRD results suggest that the cell wall of UVE14, followed by UVE8 and AGS429, was the most intact during drought stress. It was concluded that carotenoids, stomatal conductance, starch and hemicellulose could be used as physiological/biochemical indicators of drought tolerance in edamame. This information expands our knowledge of the drought defense responses in edamame, and it is essential for the physiological and biochemical screening of drought tolerance.

Abstract
Russian wheat aphid (RWA) is one of the most challenging pests for wheat crops globally. In South Africa, RWA has breached the strategy of introducing resistant genes into wheat plants, and so far, five RWA biotypes with different virulence levels have been documented in the field. Our study investigated how the cell wall plays a defensive role in Tugela-Dn1 (susceptible) and-Dn5 (resistant) cultivars infested with South African RWA-biotype 2 (RWASA2). The activities of enzymes related to defense responses were measured. The cell wall's holo-cellulose content, soluble lignin and physicochemical changes were quantified in the infested susceptible and resistant cultivars. Lastly, in vitro RWASA2 saliva-associated CWDEs activity was determined on cell wall-related model substrates. The results show that apoplastic peroxidase and β-1,3-glucanase activities were significantly higher in Tugela-Dn5 relative to the control during the infestation periods. Peroxidase activity is associated with lignin cross-linking of the cell wall, which could deter RWASA2 feeding. The total phenolic and holo-cellulose contents were significantly induced in Tugela-Dn5 at 72 and 120 h post infestation (hpi). These findings were corroborated by the FTIR results, which showed that holocellulose and lignin regions of the resistant and susceptible wheat were affected by infestation at 72 hpi. However, Tugela-Dn5 reinforced cell wall content at 120 hpi. An increased crystallinity index in the resistant cultivar validated the cell wall reinforcement at 120 hpi, while Tugela-Dn1 delayed cell wall reinforcement. This study demonstrates that cell wall reinforcement's modification is part of defense responses against Russian wheat aphid infestation.
