    Notes: A 12-year-old Korean girl gave a 9-year history of recurrent necrotizing papules and vesicles on the face, scalp and extremities. Skin biopsy specimens showed an atypical lymphoreticular infiltrate with vasculitis in the dermis and subcutis. In situ hybridization demonstrated latent infection by Epstein-Barr virus (EBV) of the lymphoid cells in the dermis. The disease was diagnosed as an EBV-associated lymphoproliferative skin eruption presenting as recurrent necrotic papulovesicles. The patient subsequently developed large granular lymphocytic leukaemia of natural killer cell origin. Our observations suggest that a patient with an EBV-associated lymphoproliferative skin eruption presenting with recurrent necrotic papulovesicles might progress to develop leukaemia as well as lymphoma.

    Notes: We report structural and ferroelectric properties of epitaxial PbZr0.53Ti0.47O3 thin films on SrRuO3 and La0.5Sr0.5CoO3 grown on (100) LaAlO3 single crystal substrates, where all the films were deposited by the pulsed-laser deposition method. While the PbZr0.53Ti0.47O3 film on La0.5Sr0.5CoO3/LaAlO3 shows (00l)-oriented heteroepitaxial growth with a rhombohedral structure, the PbZr0.53Ti0.47O3 film on SrRuO3/LaAlO3 shows a tetragonal mixture of (00l) and (h00) heteroepitaxial growth and the (00l)-oriented rhombohedral heteroepitaxial growth. The mixture of the rhombohedral and the tetragonal structures of the PbZr0.53Ti0.47O3 film on SrRuO3/LaAlO3 influences the ferroelectric properties by domain pinning. © 1999 American Institute of Physics.

    Electric field dependence of ferroelectric phase transition in epitaxial SrTiO3 films on SrRuO3 and La0.5Sr0.5CoO3 (2000)

    Notes: We report on the electric field dependence of ferroelectric phase transition in epitaxial SrTiO3 (STO) thin films grown by the pulsed-laser ablation deposition method. Metallic oxides SrRuO3 (SRO) and La0.5Sr0.5CoO3 (LSCO) were used as the bottom electrodes, and the bottom electrodes influence the dielectric properties of STO films. The change in the dielectric properties originates from the different work functions and the lattice mismatches among STO film, the bottom electrode, and the substrate. However, the field-induced ferroelectric phase transition temperatures of the STO/SRO/(100) STO and the STO/LSCO/(100) LaAlO3 systems are proportional to the applied electric field, indicating a field-induced first-order ferroelectric phase transition. © 2000 American Institute of Physics.

    Does facial sebum excretion really affect the development of acne? (2005)

    Notes: Background  It is generally accepted that the severity of acne is correlated with facial sebum secretion. However, previous studies on the relation between seborrhoea and the development of acne did not consider topographical differences in facial sebum secretion and used relatively vague acne severity grading systems.Objectives  To elucidate the relation between topographical variations in facial sebum secretion and the severity of acne in women.Methods  Forty-six female controls and 46 women with acne were included in this study. The Sebumeter® was used to measure facial sebum secretion in the following facial areas: forehead, nose, chin, and right and left cheek. We counted noninflammatory comedones and inflammatory acne lesions in the same areas. We compared sebum secretion between patients with acne and controls, and analysed the relation between the quantity of sebum secreted and the number of acne lesions.Results  Sebum secretions in the whole face and in the T- and U-zones (areas of high and low sebum secretion, respectively) were higher in patients with acne than in controls. There was no correlation between sebum quantity and acne lesion count in most facial regions.Conclusions  Increased levels of facial sebum secretion were observed in patients with acne. Our findings indicate that increased sebum levels do not directly cause development of acne lesions.

    (Z)-9-tetradecenal: a potent inhibitor of pheromone-mediated communication in the oriental tobacco budworm moth, Helicoverpa assulta (1995)

    Notes: Abstract The behavioural significance of (Z)-9-tetradecenal to male H. assulta was tested by comparing the number of moths attracted to lures containing a standard synthetic female sex pheromone with lures in which (Z)-9-tetradecenal was also added. The standard pheromone mixture used contained 1000 μg (Z)-9-hexadecenal, 50 μg (Z)-11-hexadecenal, 300 μg (Z)-9-hexadecenyl acetate and 15 μg (Z)-11-hexadecenyl acetate impregnated on rubber septa. Addition of (Z)-9-tetradecenal to the standard pheromone was shown to significantly reduce the caught of male H. assulta when added in amounts greater than 10 μg or 1% of the major pheromone component in both field and net-house experiments. The reduction in catch was found to be dependent on the quantity of (Z)-9-tetradecenal added to the standard pheromone. The implications of these results on conspecific and inter-specific pheromone-mediated communication in H. assulta and related sympatric heliothine species is discussed.

    A family of implicit partitioned time integration algorithms for parallel analysis of heterogeneous structural systems (2000)

    Notes: Abstract An implicit time integration algorithm is presented for the solution of linear structural dynamics problems on parallel computers. The present algorithm is derived from the partitioned equations of motion for a structure which consist of the equilibrium equations of each substructure due to its deformation energy, the self-equilibrium condition for each substructure under rigid-body motions, the partition boundary displacement compatibility condition and Newton's 3rd law along the partition boundary forces. A novel feature of the present algorithm is a flexibility normalization along the partitioned boundary nodes by using a localized version of the method of Lagrange multipliers, thus making the algorithm insensitive to both material and kinematic heterogeneities among the partitioned substructures. Numerical performance of the present algorithm demonstrates both its simplicity and efficiency. Hence, we recommend it for production analysis of heterogeneous structures modeled.

    A localized version of the method of Lagrange multipliers and its applications (2000)

    Notes: Abstract This paper describes a novel version of the method of Lagrange multipliers for an improved modeling of multi-point constraints that emanate from contact-impact problems, partitioned structural analysis using parallel computers, and structural inverse problems. It is shown that the classical method of Lagrange multipliers can lead to a non-unique set of constraint conditions for the modeling of interfaces involving more than two or multi-point substructural interface nodes. The proposed version of the method of Lagrange multipliers leads not only to unique construction of constraints but also encounters no singularity in modeling an arbitrary number of multi-point constraints. An important utilization of the present method is in the regularized modeling of interfaces whose rigidities are radically different from one to another. The present approach is demonstrated via several examples for its simplicity in modeling constraints, ease of implementation and computational advantages.

    Notes: Abstract The heat shock response is a highly conserved reaction common to all cells and organisms. It has been reported that hyperthermic treatment can induce the expression of the heat shock protein (HSP) and can protect cells from ultraviolet (UV) B radiation. In this study, we evaluated the effects of induced HSP70 on resistance to UV radiation. G361 amelanotic human melanoma cells were irradiated with increasing doses of UVB. UVB irradiation caused apoptotic cell death in these cells. Following transfection with MFG.hsp70.puro plasmid, the expression of HSP70 was determined. Compared to control vector-transfected cells, hsp70-transfected cells showed significantly elevated levels of HSP70 and were highly resistant to UVB irradiation. In order to investigate the effects of HSP70 on the apoptotic pathway, the changes in caspase-3 and PARP were analyzed. Following UVB irradiation, activation of caspase-3 and cleavage of PARP were observed in control vector-transfected cells, and the changes in these molecules were inhibited in the hsp70-transfected cells. These results suggest that UVB-induced apoptosis of melanoma cells is accompanied by caspase-3 activation and PARP cleavage, which can be prevented by an overexpression of HSP70.
