    Notes: We have carried out interface plasmon polariton (IPP) and specular x-ray reflectivity studies of the same multilayer structure containing a thin metallic silver film and a thin (100–600 A(ring)) smectic C* ferroelectric liquid crystal (FLC) film on a glass substrate. An additional thin nylon layer sandwiched between these two films is essential to improve the smectic FLC alignment and its stability. The specular x-ray reflectivity after each stage of layer deposition provides information on the thickness and the electron density of the individual layer. Particularly, this technique allows for the determination of the amplitude and the phase of the electronic density modulation (i.e., the smectic order parameter) of the FLC film. We demonstrate that the x-ray results are essential for the determination of the complex dielectric functions of the FLC film from the shape and the angular position of the IPP resonance. Generally, we have found that for samples with a relatively large smectic order parameter the IPP resonance can be best fitted assuming an anisotropic dielectric tensor and the presence of domains in the FLC film. For well ordered smectic C* films at room temperature, the anisotropy of the dielectric tensor is slightly higher compared to the bulk value and shows a tendency to increase with the decrease of the film thickness in ultrathin films. © 1995 American Institute of Physics.

    Notes: Keratin proteins of human epidermis have been isolated from normal and abnormal tissues. The normal proteins whether removed from living layers (prekeratin) or from the stratum corneum (keratin) are shown to consist of three chains, molecular weights 65,000 (A), 60,000 (B) and 52,000 (C). When compared with the epidermal proteins isolated from abnormal tissues, differences can be detected in the electrophoretic pattern of the subunits. In general, relative amounts of the individual chains are altered and in specific cases one or two of the polypeptides found normally are missing. All the α-fibrous proteins extracted are found to be very similar in amino acid composition.

    Anaesthesia for insertion of ear tubes in children: comparison of propofol, thiopentone and halothane (1997)

    Notes: To determine the quality of anaesthesia and speed of recovery after propofol anaesthesia for myringotomy in children, 100 children 2–12 years were randomized to one of four anaesthetic regimens for induction/maintenance: thiopentone (STP) (5 mg·kg−1)/halothane, propofol (3 mg·kg−1)/halothane, halothane/halothane or propofol (3 mg·kg−1)/propofol bolus (0.5 mg·kg−1 every 3 min (10 mg·kg−1·h−1)). Nitrous oxide (70%) in oxygen (30%) was used to facilitate insertion of an intravenous catheter and was continued throughout the anaesthetic. We found that the incidence of intraoperative movement in response to surgical stimulation was significantly greater in the prop/prop group 32%, compared with the three other groups (P〈0.02). Although some recovery variables (time to response to questions, sit unaided, tolerate oral fluids, and discharge with fluids) were achieved more rapidly by the prop/prop group than the other three groups, the times to open eyes, obey commands and, most importantly, discharge from recovery without fluids did not differ between the prop/prop and the hal/hal groups. We conclude that there is little benefit in using propofol as an induction agent alone or in combination with a propofol maintenance anaesthetic for paediatric myringotomy and tube surgery.

    Precursor keratin protein from human epidermis (1978)

    Notes: Prekeratin has been isolated from human epidermis using the method of Matoltsy for bovine nose epidermis. Analysis by sedimentation equilibrium indicates that human prekeratin is heterogeneous in solution. The molecular weight range is from about 200 × 103 to at least 2 × 106. Polyacrylamide gel electrophoresis shows three polypeptide chains of molecular weights 65,000, 60,000 and 58,000. A lower than average ratio of polar/apolar amino acid residues suggests that hydrophobic interactions are important for stability.

    The role of histidine in human epidermis (1977)

    Notes: Incorporation of radioactively-labelled histidine into half-thickness skin and into the major protein fraction extracted from epidermis by urea (protein Fraction A) has been measured and compared with the amount of labelled urocanic acid appearing in the same specimen.After a short lag period, incorporation into half-thickness skin and into protein Fraction A was foxmd to be linear up to 23 h of the study.Histidine appeared to be initially preferentially deaminated to urocanic acid. The somewhat erratic presence of urocanic acid at later periods is attributed to its high instability and solubility.

    Notes: Abstract. Respiratory syncytial virus (RSV) is a common cause of lower respiratory infections in infants. Cardiac arrhythmias are an uncommon complication in infants with RSV bronchiolitis. Presumably, the arrhythmias may be secondary to RSV pericarditis, myocarditis, or some other infection of the heart. We report on a patient with RSV bronchiolitis who had clinical myocarditis complicated by ventricular tachycardia.

    Notes: Abstract An infant is presented who at birth met criteria consistent with hypoplastic left heart syndrome. He was followed clinically and by 11 weeks of age demonstrated substantial growth of the left ventricle. He underwent successful repair of coarctation of the aorta and continues to do well with moderate aortic stenosis. The difficulties of predicting left ventricular growth and function are discussed, and management options are reviewed.

    Structure of Human Salivary α-Amylase at 1.6 Å Resolution: Implications for its Role in the Oral Cavity (1996)

    Notes: Salivary α-amylase, a major component of human saliva, plays a role in the initial digestion of starch and may be involved in the colonization of bacteria involved in early dental plaque formation. The three-dimensional atomic structure of salivary amylase has been determined to understand the structure-function relationships of this enzyme. This structure was refined to an R value of 18.4% with 496 amino-acid residues, one calcium ion, one chloride ion and 170 water molecules. Salivary amylase folds into a multidomain structure consisting of three domains, A, B and C. Domain A has a (β/α)8− barrel structure, domain B has no definite topology and domain C has a Greek-key barrel structure. The Ca2+ ion is bound to Asnl00, Arg158, Asp167, His201 and three water molecules. The Cl− ion is bound to Arg195, Asn298 and Arg337 and one water molecule. The highly mobile glycine-rich loop 304–310 may act as a gateway for substrate binding and be involved in a `trap-release' mechanism in the hydrolysis of substrates. Strategic placement of calcium and chloride ions, as well as histidine and tryptophan residues may play a role in differentiating between the glycone and aglycone ends of the polysaccharide substrates. Salivary amylase also possesses a suitable site for binding to enamel surfaces and provides potential sites for the binding of bacterial adhesins.

    Notes: Human salivary cystatin, a thiol proteinase inhibitor, has been implicated in potential antimicrobial and antiviral functions of saliva. A variant of human salivary cystatin SN expressed and purified in an Escherichia coli expression system lacking residues 12–16 near the N-terminus (Δ12–16) has been crystallized by the vapor-diffusion technique. The crystals are of the hexagonal space group P622 and have cell constants of a = 85.41, b = 85.41, c = 131.6 Å, α = β = 90, γ = 120°, and contain two molecules of molecular weight 13 500 per asymmetric unit. The crystals diffract up to a resolution of 2.2 Å and are suitable for X-ray diffraction analysis.
