    Anomalous transient diffusion of boron implanted into preamorphized Si during rapid thermal annealing (1989)

    Notes: Diffusion of boron implanted into preamorphized silicon has been studied using secondary-ion mass spectroscopy and transmission electron microscopy. A surface preamorphized layer was created by double silicon ion implantation and the as-implanted boron profiles were confined completely within the preamorphized layer. Results show that boron diffusion during rapid thermal annealing (RTA) is anomalous in nature, and that the magnitude of the anomalous diffusion depends upon the RTA temperature. While RTA at 1150 °C shows an enhanced boron diffusion compared to that in single crystalline samples, a reduced diffusion is observed in preamorphized samples annealed at 1000 °C. Results are discussed in terms of the difference in the defect evolution during RTA.

    Notes: Aims: The histopathology of the Sauropus androgynus (SA)-constrictive bronchiolitis obliterans (BO) is still controversial. A recent report using pneumonectomy specimens showed that the major histopathology was obliterative arteriopathy with segmental necrosis of small bronchi instead of constrictive BO as previously described.Methods and results: We analysed semiquantitatively and immunohistochemically the histopathology of one pneumonectomy and four biopsies specimens of SA-associated lung disease. We found a significant number of constrictive and obliterative bronchioles 1 mm or less in diameter and segmental inflammatory destruction with complete luminal obliteration of the bronchi less than 3 mm in diameter in the pneumonectomy specimen (37% and 25%, respectively). Fibromuscular intimal sclerosis of the bronchial arteries was identified in 15% of the bronchi 4 mm or less in diameter. The inflammation in these airways was composed predominantly of T-lymphocytes, macrophages, mast cells and eosinophils. They were present throughout the evolutionary stages of the bronchiolitis ranging from early oedematous to the late fibrotic obliterative stage. Double immunohistochemical stains revealed negative proliferative cell nuclear antigen for most of the T-lymphocytes and macrophages but positive for fibroblasts.Conclusions: A more accurate histopathological designation of the SA-associated lung disease should be constrictive obliterative bronchitis/bronchiolitis, with the participation of T-lymphocytes, macrophages, mast cells, eosinophils and fibroblasts in its morphogenesis. The persistent accumulation of inflammatory cells was mediated predominantly by continued recruitment to the site of injury from the bloodstream, resulting eventually in the irreversible fibrosis of the bronchioles and the bronchi less than 3 mm in diameter. Obliterative arteriopathy is suspected of being only an indirect contributing factor.

    Notes: Although the eradication of Helicobacter pylori infection benefits patients with gastric or duodenal ulcers, the value of eradicating the infection in the patients with functional dyspepsia (FD) remains controversial.〈section xml:id="abs1-2"〉〈title type="main"〉Aims:To determine whether eradicating H. pylori can prevent the subsequent development of ulcers or relieve the symptoms of functional dyspepsia patients.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:In a double-blind, placebo-controlled trial, 161 patients infected with H. pylori who had functional dyspepsia were randomly assigned to 7 days of treatment with a lansoprazole-based triple therapy or placebo and then followed for 1 year. The main outcome measures were the development of peptic ulcers and the resolution of symptoms.〈section xml:id="abs1-4"〉〈title type="main"〉Results: H. pylori was eradicated in 63 out of 81 patients (78%) in the treatment group and none of the 80 patients (0%) in the placebo group. During the follow-up period, two patients in the treatment group and six patients in the placebo group developed peptic ulcers at repeat endoscopy (2.5% vs. 7.5%; 95% CI: –12 to 2). The reduction in ulcer rates was statistically significant in the ‘ulcer-like’ sub-group (0% vs. 16.7%; 95% CI: –32 to –2), but not in the ‘dysmotility-like’ and ‘unclassifiable’ sub-groups. Regarding symptom response, the resolution rates of symptoms were similar between the treatment and placebo groups (58.0% vs. 55.0%, 95% CI: –12 to 18). Additionally, no significant differences existed in the symptom responses between the treatment and control arms in each of the dyspepsia sub-groups.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions:Eradicating H. pylori can prevent the subsequent development of peptic ulcers in the patients with ‘ulcer-like’ functional dyspepsia. However, this approach does not significantly reduce the symptoms of functional dyspepsia patients.

    Risks of interleukin-1 genetic polymorphisms and 〈fr〉Helicobacter pylori〈/fr〉 infection in the development of gastric cancer (2004)

    Notes: Background : The host genetic factors that determine the clinical outcomes of Helicobacter pylori-infected individuals remain unclear.Aim : To elucidate the risks of host interleukin-1 (IL-1) genetic polymorphisms and H. pylori infection in the development of gastric cancer.Methods : In a case–control study of 164 controls and 142 patients with gastric cancer, the IL-1B-511 biallelic polymorphisms and the IL-1RN penta-allelic variable number of tandem repeats were genotyped.Results : The carriage of IL-1RN*2, male gender, old age and H. pylori infection independently increased the risk of gastric cancer, with odds ratios of 3.3 [95% confidence interval (CI), 1.4–7.7], 2.1 (95% CI, 1.2–3.8), 5.3 (95% CI, 3.1–9.0) and 2.2 (95% CI, 1.3–3.8), respectively. H. pylori-infected individuals who were carriers of IL-1RN*2 showed increased risks of both intestinal and diffuse types of gastric cancer, with odds ratios of 11.0 and 8.7, respectively. In addition, these individuals also had a higher score of intestinal metaplasia in the corpus than did uninfected non-carriers.Conclusions : This study is the first to verify IL-1RN*2 as an independent factor governing the development of gastric cancer in Asian individuals. A combination of H. pylori testing and host genotyping may target the eradication of H. pylori to high-risk individuals.

    Notes: The bursting strength and inflated deflection of linear low density polyethylene (LLDPE), oriented polypropylene (OPP), flexible poly(vinyl chloride) (PVC), poly(ethylene terephthalate) (PET), and polyurethane (PUR) films of different thicknesses were investigated with the pneumatic bursting method. The study showed the bursting air pressure is directly proportional to the thickness of LLDPE, OPP, and PET films. The effect of different membrane diameters on the change of the bursting properties in OPP and PUR film was also investigated. The results showed that the bursting properties are inversely proportional to the membrane diameter. Furthermore, biaxial stress-strain exerted on the pole region of the tested films was studied. The results denoted that the relationship between the biaxial and uniaxial tensile stress-strain was considered for two types of film: (1) Film that presented an isotropic tensile behavior showed that the tangential stress-strain is higher than the tensile stress-strain. (2) Film that presented an anisotropic tensile behavior showed that the tangential stress-strain is determined by the weaker tensile stress-strain values between two directions.
