- Objective. This study was conducted to investigate the prevalence of celiac disease (CD) in children and adolescents at diagnosis of insulin- dependent diabetes mellitus (IDDM) before insulin treatment was started. Material and Methods. At diagnosis of IDDM, and before treatment was started, 115 children and adolescents were screened for IgA-antiendomysium (EMA) and IgA-antigliadin antibodies (AGA). Those found to be EMA-positive and/or AGA- positive were investigated further with intestinal biopsy. Results. Of the 115 patients, 2 had known CD at diagnosis of IDDM; of the remainder of patients, 6% (7/113) were found to be EMA-positive and 9% (10/113) were found to have AGA levels above normal. Of the 6 patients who underwent biopsy, 5 manifested villous atrophy. In addition, 2 patients with high EMA and AGA antibody titers refused biopsy, and 4 patients with low EMA and/or AGA titers were found to have normal titers at control before biopsy decision. Conclusion. Because the prevalence of CD at diagnosis of IDDM would seem to be 6% to 8%, screening for CD seems to be justified among patients with newly diagnosed IDDM.

- We report the fabrication of InP/air-gap Fabry-Perot resonant cavities with an improved tunability characteristic achieved through the micromachining of more flexible suspended InP beams. The micromechanical structures are electrostatically actuated. A tuning range of 55 nm is demonstrated for an actuation voltage of 12 V. The low leakage current, of less than 10 µA for a bias of up to 30 V, provides a low actuation power. The tunable air-gap cavities are fabricated by selective wet etching of InGaAs sacrificial layers. An FeCl3 based etchant is used to completely remove the InGaAs material without affecting the thickness of the InP layer. The anisotropy of the etch rate of InGaAs was also investigated and exploited in the micromachining process.

- Nine low molecular weight nerve growth factor (NGF)-like peptides have been designed to mimic the putative receptor-binding epitope of NGF defined by two beta-hairpin loops. Eight different spacers were used as variable links between the beta-loop amino acid residues, which from mutagenesis experiments were found to play an important role in the biological activity of NGF. These spacers were amino acids, natural or non-natural, differing in length (5-13 A) and polarity. The peptides were synthesized via the Fmoc solid-phase peptide synthesis and purified by reversed-phase HPLC. Their primary sequences were analyzed by a combination of automated Edman degradation and mass spectrometry. The peptides were tested using two different biological assays, the fibre outgrowth from chick embryonic sympathetic ganglia and the PC12 cell differentiation assay. Weak antagonistic effects could be observed for some peptides.
