[A multi-phase flow detector system based on gamma-ray].

In the present paper, a gamma-ray based on-line detection system was designed for multi-phase flow measurement, where the complicated fluid property of multi-phase flow can be studied by using the principle of ray transmission. The system is made up of three parts, i. e.

Thinking path and method for establishing the disease/Chinese medicine syndrome conjugated pattern of a mammary hyperplasia animal model.

Mammary hyperplasia (MHP) is the most commonly encountered mammary disease in women at the child-bearing stage. Especially, atypical hyperplasia which belongs to the precancerous category, is the disease for class I prevention of breast cancer. Therefore, advancing the clinical efficacy of MHP treatment is of critical importance.

Expression, identification and biological effects of a novel VPAC2-specific agonist with high stability and bioactivity.

The development of rBAY, a recombinant peptide with the similar sequence of synthetic BAY55-9837, as a potential peptide therapeutic for type 2 diabetes is still a challenge mainly because of its poor stability in aqueous solution. To improve the peptide stability and bioactivity and investigate its biological effects for VPAC2-specific activation, RBAYL with 31 aa was designed based on sequence alignments of pituitary adenylate cyclase-activating peptides (PACAPs), vasoactive intestinal peptide (VIP), and related analogs and generated through sitedirected mutagenesis. Stability analysis showed that the prepared RBAYL with three mutations (N9Q, V17L, and N28K) were much more stable than rBAY.

Malignant neurilemoma with xeroderma pigmentosum.

Unlabelled: Xeroderma pigmentosum is a rare autosomal recessive disease characterised by hypersensitivity to sunlight, and is associated with a high incidence of skin cancer. We report a case of xeroderma pigmentosum with malignant neurilemoma in a 46-year-old woman which is unique due to its presentation, which was confirmed histopathologically.

[Long-term and short-term effects of propionic/acetic acid ratios on metabolism of glycogen-accumulating organisms].

Three activated sludges enriched with glycogen accumulating organisms (GAO) were acclimatized respectively with different ratios of propionic to acetic acid (i.e. biomass SBR-A, C and E) .

In situ surface-enhanced IR absorption spectroscopy on CO adducts of iron protoporphyrin IX self-assembled on a Au electrode.

The surface coordination chemistry of carbon monoxide with the reduced form (Fe(II)PP) of iron(III) protoporphyrin IX (Fe(III)PP) monolayer self-assembled on a Au electrode in 0.1 M HClO4 was studied for the first time by using in situ ATR-surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS). Both mono- and biscarbonyl adducts [simplified as Fe(II)(CO)PP and Fe(II)(CO)2PP, respectively] were detected, depending on the history of potential control.

Ubiquitous strategy for probing ATR surface-enhanced infrared absorption at platinum group metal-electrolyte interfaces.

A versatile two-step wet process to fabricate Pt, Pd, Rh, and Ru nanoparticle films (simplified as nanofilms hereafter) for in situ attenuated total reflection Fourier transform infrared (ATR-FTIR) study of electrochemical interfaces is presented, which incorporates an initial chemical deposition of a gold nanofilm on the basal plane of a silicon prism with the subsequent electrodepostion of desired platinum group metal overlayers. Galvanostatic electrodeposition of Pt, Rh, and Pd from phosphate or perchloric acid electrolytes, or potentiostatic electrodeposition of Ru from a sulfuric acid electrolyte, yields sufficiently "pinhole-free" overlayers as evidenced by electrochemical and spectroscopic characterizations. The Pt group metal nanofilms thus obtained exhibit strongly enhanced IR absorption.

[Levels of serum interleukin-15 and the expression of T-helper lymphocyte subsets in peripheral blood of children with juvenile rheumatoid arthritis].

Objective: To study the changes of serum interleukin-15 (IL-15) levels and the expression of CD4(+)T (T-helper lymphocyte) subsets CD4(+)CD45RA(+) and CD4(+)CD45RO(+) in peripheral blood of children with juvenile rheumatoid arthritis (JRA).

Methods: The serum concentration of IL-15 was detected using ELISA in 39 children with JRA. The expressions of CD4(+)CD45RA(+)T and CD4(+)CD45RO(+)T in peripheral blood were detected by flow cytometry in 24 out of the 39 patients with JRA.

Extending in situ attenuated-total-reflection surface-enhanced infrared absorption spectroscopy to ni electrodes.

Surface-enhanced infrared absorption spectroscopy (SEIRAS) in the attenuated-total-reflection configuration (ATR-SEIRAS) has been applied for the first time to Ni electrodes. SEIRA-active Ni electrodes were obtained through initial chemical deposition of a 60-nm-thick Au underlayer on the reflecting plane of an ATR Si prism followed by potentiostatic electrodeposition of a 40-nm-thick Ni overlayer in a modified Watt's electrolyte. The Ni nanoparticle film thus obtained exhibited exceptionally enhanced IR absorption for the surface probe molecule CO while maintaining unipolar and normally directed bands.

[Expression of platelet CD62p gene and leucocyte HSP70 gene in patients with blood stasis syndrome MA].

Objective: To investigate microcosmic essentials of blood stasis syndrome (BSS) at the gene level.

Methods: One hundred and sixty patients with hypertension or diabetes mellitus, BSS or non-BSS, were strictly selected in disease-syndrome integrated mode according to diagnosis standard. The expression of CD62p gene and HSP70 gene in them were observed, compared and analyzed with blood biochemical indexes by experimental techniques, and compared to those in healthy subjects as control, for exploring the microcosmic mechanism and evolutive rules of BSS formation at the gene level.

Expression of IgSF in salivary adenoid cystic carcinoma and its relationship with invasion and metastasis.

Background: The aim of the present work was to study the potential effect of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and neural cell adhesion molecule (NCAM) of immunoglobulin superfamily on the invasion and metastasis of salivary adenoid cystic carcinoma (SACC).

Method: The expressions of ICAM-1, VCAM-1 and NCAM of forty cases with SACC were examined by immunohistochemical methods using respective kits.

Results: A significant relation showed between the expression level and histological differentiation, expression of ICAM-1 and VCAM-1 in solid SACC was greatly increased compared with NCAM; SACC with metastatic lymph node or local recurrence displayed significant relationship to the up-regulation of ICAM-1 and VCAM-1, and to the down-regulation of NCAM.

Objective: To investigate the expression of matrix metalloproteinase-1 (MMP-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor-beta 1 (TGF-beta 1) in human middle ear cholesteatoma.

Methods: Immunohistochemical staining was used to detect the expression of TGF-beta 1, MMP-1 and TIMP-1 in the cholesteatoma (41 cases) and the skin of external auditory meatus (15 cases).

Results: The percent of positive expression of TGF-beta 1, MMP-1 and TIMP-1 in cholesteatoma was 95.
