    Notes: A confocal theta microscope using a single water-immersion objective lens is described. The system is based on the Zeiss Axioplan universal microscope, such that the illumination light is coupled into, and the detected light out of, the microscope optics via optical fibers attached to the reflector slider of the microscope. Conventional wide-field, laser-scanning confocal, confocal theta, and 4Pi-confocal theta microscopy modes are available with the system. As the design can be easily adapted to other microscopes, objective lenses, and wavelengths, it allows confocal theta techniques to be implemented in many standard systems. The design constraints and specifications for the microscope are given, as well as a demonstration of its performance. © 1998 American Institute of Physics.

    Notes: The change in position of fluorescent beads captured inside the focal volume of optical tweezers is monitored using fluorescence emission induced by two-photon absorption of a continuous-wave Nd:YAG laser (λ=1064 nm). The displacement of a bead due to interactions with its environment leads to a fluorescence intensity variation that is used to design a novel spatial sensor. We determine changes in the axial position of a CY3-labeled latex bead with a diameter of 1.03 μm to a precision better than 10 nm. At an intensity of 600 mW/ μm2 the two-photon bleaching rate is lower than 50% per 2000 s. © 1996 American Institute of Physics.

    Notes: We examined the role of psychopathic traits on physiological responding during a concealed information polygraph test among prison inmates (n=40). The Psychopathic Personality Inventory (Lilienfeld & Andrews, 1996) was used to assess psychopathic traits. Cardiac, electrodermal, and respiratory responses were measured while participants were presented with personal and control names and asked to conceal recognition of personal information. We first piloted the present concealed information test in a sample of undergraduates (n=27). Enhanced orienting to concealed information compared to control information was observed in both prisoners and undergraduates. However, prisoners scoring high on the Impulsive Antisociality factor of the Psychopathic Personality Inventory (PPI-II) exhibited reduced electrodermal responding. This finding indicates that the sensitivity of the concealed information test may be decreased in antisocial offenders.

    Notes: Summary.— The basement membrane antibodies in 3 sera of patients with bullous pemphigoid were studied by means of indirect immunofluorescent staining chessboard titrations on monkey, rabbit and guinea-pig lip tissue. Comparisons of the results of these studies with those obtained in previous studies of this type with 2 other sera, revealed wide variations in the spectra of specificities of the bullous pemphigoid antibodies. Monkey oral or oesophogeal mucosa appears to be the substrate of choice for routine tests for these antibodies, although this must be regarded as an approximation of the “ideal antigen”.The implication of these findings are discussed both from the practical and theoretical points of view.

    Notes: Background. In 1990 a new disease-associated antinuclear antibody was first recognized as a specific immunologic marker for a chronic form of ulcerative stomatitis (cus). Methods. Another case is reported herein and the subject of chronic ulcerative stomatitis with stratified epithelium-specific antinuclear antibodies (SES-ANA) is reviewed. Intraoral biopsies from this patient were submitted for microscopic examination and direct immunofluorescence. Indirect immunofluorescence studies were also performed. Serial SES-ANA titers were obtained with the patient on maintenance treatment with hydroxychloroquine. A skin biopsy of a recent lichenoid eruption was obtained and skin explants grown in the serum of this patient were studied in tissue culture with reference to SES-ANA binding and complement fixation. Results. Biopsy and serum studies confirmed a diagnosis of cus with SES-ANA in the patient reported. Skin biopsy showed lichen planus. The patient was treated with hydroxychloroquine with a favorable response. Serial SES-ANA titers did not parallel the disease activity. Among the substantive observations made from skin explants cultured in the serum of this patient was widespread fixation of C3 to the nuclei of basal cells. Conclusions. The case described herein extends the findings in cus to include lichenoid skin lesions. Records show that at least four of 11 cases of cus had skin lesions, whereas all had oral lesions. Stratified epithelium-specific antinuclear antibodies serve as the key marker of cus. Skin explants grown in the serum of this cus patient bind SES-ANA in tissue culture. Sections of explants fix complement. Titers of SES-ANA have been reported to parallel disease activity in one case, but not in the present case. Thus, there appears to be case-to-case variation. The treatment of choice for cus is hydroxychloroquine.

    Notes: The adsorption of CO on Cu (211), serving as model system for the adsorption of CO in stepped surfaces, has been investigated using electron energy loss spectroscopy (EELS). At a surface temperature of 110 K, CO adsorbs nondissociatively and is drawn exclusively to descending step sites in this system. On-top and bridge sites are sequentially populated with the CO axis being perpendicular to the surface. In addition, at low coverage, a molecular state is observed, for which the CO axis is strongly inclined. © 1999 American Institute of Physics.
