    Notes: Summary The genome ofGlycine max (L.) Merr. cv. “Dare” contains a chlorophyll a/b binding (Cab) protein gene family consisting of 10 genes. The primary structures of two linkedCab genes (Cab 4 andCab 5) were determined. A comparison of the nucleic acid and predicted amino acid sequences ofCab 4 andCab 5 revealed a high degree of similarity (96% and 98%, respectively). Phylogenetic inferences drawn from sequence comparisons between previously characterized soybeanCab 1, 2, and 3 andCab 4 and 5 suggested that soybeanCab 3 was an evolutionarily distant member within this family. We further investigated the molecular evolution of theCab gene family by comparing nucleotide sequences from 25 differentCab genes representing diverse phylogenetic taxa including moncot and dicot species. Phylogenetic inferences from these data support existing morphological phylogenies in that all species within one family clustered together. These data suggested that the Solanaceae were more evolutionarily distant from the monocots than the Fabaceae and Brassicaceae. In addition, these data supported the theory thatCab Type I and II genes originated prior to divergence of the monocots and dicots.

    Notes: Summary A prospective study was made to evaluate the effect of intrathecal injection of iohexol on brainstem auditory evoked potentials (BAEP) following myeloradiculography, in order to assess its neurotoxicity. Thirty patients who received contrast medium via the lumbar route for myeloradiculography (cervical level=25 patients, lumbar level=5 patients) had BAEP examinations before, 2 h and 24 h after myelography. No statistically significant prolongation of absolute and interpeak latencies was found between premyelographic and postmyelographic records. Low incidence (20%) of insignificant clinical adverse effect following myelography was also noted in the same group of patient.

    Spatial and temporal expression of Cab mRNAs in cotyledons of the developing soybean seedling (1992)

    Notes: Abstract Changes in the temporal and spatial distribution of the mRNAs for the chlorophyll-a/b-binding-protein gene (Cab) in cotyledons from developing soybean (Glycine max (L.) Merr.) seedlings were studied. Cab mRNAs could be detected in the polysomal polyadenylated poly(A)+ mRNA population of cotyledons within 3 d after start of imbibition, prior to their emergence from soil, and declined prior to the onset of cotyledonary senescence. The Cab mRNA levels were compared to the levels of rbcS (ribulose-1,5-bisphosphate carboxylase small subunit) mRNAs in cotyledons and distinct differences in their expression programs were noted. Quantitative analyses with S1 nuclease were used to monitor the accumulation of the mRNAs of individual members of the Cab gene family. Cab 3, Cab 4, and Cab 5 mRNAs were differentially regulated in the cotyledons during post-germinative development. Cab 4 was the most abundant Cab gene mRNA representing approx. 4.3% of the cotyledonary polysomal poly(A)+ mRNA population. In-situ hybridizations using methacrylate-imbedded tissue and 3H-antisense- and -sense-strand RNA probes were used to determine the qualitative and quantitative distribution of Cab RNAs in cotyledonary cells. Cab RNAs were most abundant in the palisade cells. These results indicate an interaction of both developmental and environmental cues in modulating the expression of the Cab gene family in soybean cotyledons.

    Effects of concanavalin A on desensitization kinetics of GABA responses inAchatina fulica neurons (1995)

    Notes: Abstract The effects of the lectin concanavalin A (Con A), on the kinetics of desensitization of the responses of voltage clampedAchatina fulica LP5 neuron to microperfused acetylcholine (ACh) and GABA were compared. Both ACh and GABA elicited increases in chloride conductance which decayed biphasically during prolonged applications of these agonists; an initial rapid decay was followed by a later slow decay. Con A (5 μg/ml) accelerated both the fast and the slow decays of responses to ACh. Con A (5 μg/ml) also accelerated the fast decay of responses to GABA, but the slow decay was unaffected, even by 20 μg/ml or more of the lectin. It is suggested that, at least in the case of GABA receptor, the fast and slow decays involve distinct desensitization kinetics. The effects of Con A on the desensitization of the ACh and GABA responses were reversed byd-mannose, a competitive and specific inhibitor of Con A binding to membrane sugar residues. These results provide further evidence that receptor desensitization can be influenced by perturbing the sugar moieties associated with the subunits comprising these signalling macromolecules. The carbohydrate residues may play an important role in regulating desensitization of transmitter receptors.

    Keywords: Discrete Riccati equation ; robust stabilization ; time-delay systems ; robust stabilizability criterion ; state feedback control laws

    Topics: Mathematics
    Notes: Abstract In this paper, we address the estimation problem for the solution of the discrete algebraic matrix Riccati equation. Both upper and lower bounds are measured. Compared to the majority of the approaches proposed in the literature, the present results are sharper. We also apply the results obtained to solve the robust stabilization problem of discrete time-delay systems. A robust stabilizability criterion and the corresponding state feedback control law are proposed. Furthermore, the tolerable bound of the delay term is also estimated. Finally, numerical examples are given to demonstrate the applications of the results.

    The diffusivity of potassium chloride and sodium chloride in concentrated, saturated, and supersaturated aqueous solutions (1985)

    Notes: The diffusion coefficients of potassium chloride and sodium chloride were measured in concentrated, saturated, and supersaturated solutions at 25°C employing Gouy interferometry. The results indicate a maximum in the diffusivity vs. concentration curve near saturation followed by a rapid decline in diffusivity toward zero with increasing concentration in the supersaturated region. This behavior supports the idea that the diffusion coefficient approaches zero at the spinodal concentration. The data were successfully correlated by modifying an empirical activity coefficient equation (Robinson and Stokes, 1955) to account for molecular cluster effects and employing the calculated activity coefficients along with a predictive equation for diffusivity in electrolytes (Robinson and Stokes, 1955).
