Expression of MUC-1 and MUC-2 was investigated with immunohistochemical staining (PAP-method) in 5 cases of adenomas and in 60 cases of colorectal adenocarcinomas. The expression of MUC-1 and MUC-2 can be useful for diagnosis and prognosis in patients with colorectal carcinoma. 相似文献

A process of atomic layer deposition (ALD) combined with self-assembled monolayers (SAMs) was used to investigate the possible modification of the wetting properties of polyurethane (PUR) paint surfaces without altering their original hue. First, we used an ALD process to produce thin and uniform Al2O3 coatings of these surfaces at temperatures as low as 80 °C. We then successfully achieved the addition of 16-phosphono-hexadecanoic acid (16-PHA) SAMs to the Al2O3-coated paint samples. Given initial hydrophobicity, which however was not stable over time, Al2O3 coatings reduced the contact angle of the PUR surfaces from 110 to 10°. Addition of SAMs on the Al2O3 coatings induced a sustained reduction in their contact angles to 60–70°, and aging of the samples revealed a further decrease to 25–40°. Testing of the Al2O3/16-PHA coating in a Weather-Ometer (WOM) revealed its durability even under harsh outdoor conditions. These experimental results show that by combining ALD with SAMs it is possible to produce durable coatings with modified hydrophilic/hydrophobic properties that are stable over time. The use of SAMs with different end-groups may allow fine-tuning of the coating''s wetting properties.A process of atomic layer deposition (ALD) combined with self-assembled monolayers (SAMs) was used to investigate the possible modification of polyurethane (PUR) paint surface wetting properties without altering their original hue. 相似文献

The experience of estimation of the state and the results of treatment of 300 patients with the combined craniocerebral trauma (CCT) is summarized. The injured persons with severe CCT and severe outcranial injuries were included in the 1st group, with severe CCT and nonsevere outcranial injuries--in the 2nd group, with nonsevere CCT and severe outcranial injuries--in the 3d group, with nonsevere CCT and nonsevere outcranial injuries--in the 4th group. The dominating, competing and accompanying injuries, determining the surgical treatment tactics, were marked out in every group. The differentiative therapy general principles were marked out. 相似文献

We report a case of a patient with clinical features of progressive supranuclear palsy and raised titres of anticardiolipin antibodies in blood, thrombocytopenia and livedo reticularis on skin. Magnetic resonance imaging of brain and isotope scan of brain were distinctive of vascular disorder. 相似文献

Sudden infant death syndrome (SIDS) has been associated with the volatilization of arsenic, antimony or phosphorus compounds from infants' bedding material by micro-organisms, the so-called 'toxic gas hypothesis'. The volatilization of arsenic by aerobic micro-organisms isolated from new sheepskin bedding material, as well as on material used by a healthy infant and by an infant who perished of SIDS, was examined. Three fungi were isolated from a piece of sheepskin bedding material on which an infant perished of SIDS, which methylated arsenic to form trimethylarsenic(V) species, precursors to volatile trimethylarsine. These three fungi were identified as Scopulariopsis koningii, Fomitopsis pinicola and Penicillium gladioli by their 26S-ribosomal RNA polymerase chain reaction products. These fungi were not previously known to methylate arsenic. The volatilization of arsenic by these three fungi was then examined. Only P. gladioli volatilized arsenic and only under conditions such that the production of sufficient trimethylarsine to be acutely toxic to an infant is unlikely. S. brevicaulis grew on the sheepskin bedding material and evolved a trace amount of trimethylarsine. Known human pathogens such as Mycobacterium neoaurum and Acinetobacter junii were isolated from used bedding. 相似文献
