Psoriasis is capable of presenting in a variety of clinical and pathologic guises including a rarely described variant variably termed hypertrophic or verrucous psoriasis. Herein, we describe the clinical and pathologic attributes of a large series of patients with this unusual variant of psoriasis and distinguish it from other entities in the differential diagnosis. The histopathologic features and clinical and demographic attributes of a series of 12 cases from 12 patients were reviewed by a single dermatopathologist (mm). The 12 patients consisted of 7 males and 5 females with an average age of 61.8 years (males 38- 93 years, females 41- 71 years). Eight of the patients were Caucasian, 3 Hispanic and 1 African- American. Six of the lesions were located on the knees, 4 involved the elbows, and 2 were seen on the dorsum of the hands (metacarpal- phalangeal joint). The clinical appearance of the lesions consisted of flesh- toned to white mammillated plaques (8 cases) and coalesced papules (4 cases). Each of the biopsies showed regular psoriasiform epidermal hyperplasia with acanthosis, hyperkeratosis, and either spongiform neutrophilic or munro micro- abscesses. In addition, each showed papillomatosis with bowing of the peripheral rete ridges toward the center of the lesion (buttressing). At high power, epidermal neutrophils were seen in particular surmounting the tips of the suprapapillary plates with accompanying serum. Hypergranulosis and koilocytic change were not observed in any of the lesions. Human papilloma virus (HPV) immunostaining and periodic acid Schiff (PAS) special staining for fungi were negative. Verrucous psoriasis is a distinctive variant of psoriasis with overlapping clinical and pathologic features that might prompt consideration of verruca vulgaris. The presence of epidermal papillomatosis and epidermal buttressing seen in these lesions is reminiscent of the histologic features of verruca vulgaris. Similarly, the presence of coalesced papules m

摘要很多治疗癌症的方法都直接或间接地影响肿瘤血管。动态对比增强mRI(DCE-mRI)已经成为临床前和临床实验早期阶段研究肿瘤血管的重要方法。对于这些临床实验,需保证测量过程(即图像采集和分析)的有效进行以及在各个研究中心之间的一致性。随着技术进步,不仅能够潜在改善敏感性和生理相关性,而且在改善研究中心之间的技术差异方面也具有很大空间。

Formation of Extended Covalently Bonded Ni Porphyrin Networks on the Au（lll） Surface

The growth and ordering of {5,10,15,20-tetrakis（4-bromophenyl）porphyrinato}nickel（II）（NiTBrPP） molecules on the Au（111） surface have been investigated using scanning tunnelling microscopy, X-ray absorption, core-level photoemission, and microbeam low-energy electron diffraction. When deposited onto the substrate at room temperature, the NiTBrPP forms a well-ordered close-packed molecular layer in which the molecules have a flat orientation with the porphyrin macrocycle plane lying parallel to the substrate. Annealing of the NiTBrPP layer on the Au（111） surface at 525 K leads to dissociation of bromine from the porphyrin followed by the formation of covalent bonds between the phenyl substituents of the porphyrin. This results in the formation of continuous covalently bonded porphyrin networks, which are stable up to 800 K and can be recovered after exposure to ambient conditions. By controlling the experimental conditions, a robust, extended porphyrin network can be prepared on the Au（111） surface that has many potential applications such as protective coatings, in sensing or as a host structure for molecules and clusters.

The encapsulation of individual pairs of plasmonic nanoparticles(NPs)in liposomes is introduced as a new strategy for utilizing plasmon coupling to monitor interactions between co-confined NPs in a nanoconfinement that ensures high local NP *** apply the approach to monitor transient binding contacts between noncovalently tethered 55 nm diameter gold NPs,which were functionalized with cytosine(C)-rich DNAs,in acidic and mildly basic buffer *** pH=8,a rich spectral dynamics indicates DNA-mediated transient binding and unbinding of co-confined NPs due to weak attractive interparticle interactions.A decrease in pH from 8 to 4 is observed to favor the associated state for some co-confined NPs,presumably due to a stabilization of the bound dimer configuration through noncanonical C-C^(+)bonds between the DNA-functionalized *** nanoemitters whose spectral response switches in response to chemical cues(in this work pH)represent optical transducers with a rich application space in chemical sensing,cell analysis and nanophotonics.

Because mIPs have outstanding advantages such as predetermined selectivity,simple and convenient preparation,robustness in organic solvents and acidic or basic reagents,and durability to high temperature, molecular imprinting has drawn extensive attention.

Investigation by AES, EELS and TRIm Simulation method of InP(100) Subjected to He<sup>+</sup>and H<sup>+</sup>Ions Bombardment

引用

materials Sciences and Applications 2011年第5期2卷 421-426页

作者： mohamed Ghaffour Abdellaoui Abdellaoui Abdellah Ouerdane m'Hammed Bouslama Christian Jardin 不详

Auger Electron Spectroscopy (AES) and Electron Energy Loss Spectroscopy (EELS) have been performed in order to investigate the InP(100) surface subjected to ions bombardment. The InP(100) surface is always contaminated by carbon and oxygen revealed by C-KLL and O-KLL AES spectra recorded just after introduction of the sample in the UHV spectrometer chamber. The usually cleaning process of the surface is the bombardment by argon ions. However, even at low energy of ions beam (300 eV) indium clusters and phosphorus vacancies are usually formed on the surface. The aim of our study is to compare the behaviour of the surface when submitted to He+ or H+ ions bombardment. The helium ions accelerated at 500 V voltage and for 45 mn allow removing contaminants but induces damaged and no stoichiometric surface. The proton ions were accelerated at low energy of 500 eV to bombard the InP surface at room temperature. The proton ions broke the In-P chemical bonds to induce the formation of In metal islands. Such a chemical reactivity between hydrogen and phosphorus led to form chemical species such as PH and PH3, which desorbed from the surface. The chemical susceptibly and the small size of H+ advantaged their diffusion into bulk. Since the experimental methods alone were not able to give us with accuracy the disturbed depth of the target by these ions. We associate to the AES and EELS spectroscopies, the TRIm (Transport and Range of Ions in matter) simulation method in order to show the mechanism of interaction between Ar+, He+ or H+ ions and InP and determine the disturbed depth of the target by argon, helium or proton ions.

Chemical Durability, Properties and Structural Approach of the Glass Series xFe₂O₃-(45-x) PbO-55P₂O₅ (with 0 ≤ x ≤ 20;mol%)

引用

New Journal of Glass and Ceramics 2023年第1期13卷 1-16页

作者： Radouane makhlouk Zineb Chabbou Yassine Er-rouissi m’hammed Taibi Said Aqdim Laboratory of materials Engineering for Environment and Valorization Faculty of Sciences Hassan II University Ain Chock Casablanca Morocco Physico-Chemistry Laboratory of Inorganic and Organic materials ENS University Md V Rabat Morocco mineral Chemistry Department of Chemistry Faculty of Science Hassan II University Ain Chock Casablanca Morocco

The synthesis for glasses series xFe2O3-(45-x)PbO-55P2O5, (with 0 ≤ x ≤ 20;mol%) carried out in a temperature (1050 ± 10)°C, leads to obtaining transparent glasses, brown in color and with a non-hygroscopic appearance. The study of glasses dissolution rate, immersed in distilled water at 90°C for 24 days, indicates a considerable chemical durability. The increase in the Fe2O3 content in the vitreous network to the detriment of PbO is a favorable factor for the chemical durability improvement. Different techniques have been used such as X-ray diffraction, infrared spectroscopy, DSC, SEm and density for the study of these glasses. These techniques have led to establish correlations between chemical and structural properties. Thus the results obtained confirmed the creation of P-O-m bonds (m = Pb, Fe) with a strongly covalent nature to the detriment of the hydrated P-O-P bonds and led to the formation, mainly, of pyrophosphate groups. The low melting point of Pb-O makes it possible to play an important role, at the same time, on the viscosity, on the equilibrium between the vitreous bath and the crystallites formed. The dissolution rate obtained is 100 times smaller than that of silicate glasses used as an alternative form for the vitrification of radioactive waste.

采用基于广义梯度近似(GGA)的密度泛函方法(DFT)对石墨烯和卷曲后的关联碳纳米管(8,0)进行了理论研究。结果表明石墨烯每行斜键键长呈AAB周期变化,关联碳纳米管斜键长度成AABB规则变化,竖键长度均不变。石墨烯的密立根电荷数值大小分布无明显规律,内部原子多为正值,外部多为负值。关联碳纳米管的密立根电荷分布相对较有规律。碳纳米管的内部碳原子也有吸引电子的能力,从而与其它原子形成离子性键。两者在费米能级态密度大部分均由p轨道贡献。但是关联碳纳米管的费米能级也有一部分来自于s轨道电子的贡献,而石墨烯则几乎没有来自s轨道的贡献。
