Role of pH on Nanostructured SERS Active Substrates for Detection of Organic Dyes.

Surface Enhanced Raman Spectroscopy is commonly used as analytical improvement to conventional Raman spectroscopy, able to respond to qualitative diagnostic enquiries, which involve low-concentrated molecular species in complex matrix. In this paper, we described fabrication, characterization and testing of a type of SERS-active substrates realized specifically to detect pigments in work of art. In particular, we detailed the SERS activity of nanostructured noble metal films deposited by pulsed laser ablation onto glass and polishing sheets substrates.

Prognostic Role of Krüppel-Like Factors 5, 9, and 11 in Endometrial Endometrioid Cancer.

Background And Objective: Krüppel-like factors (KLFs) are transcription factors with the ability to mediate cross-talk with signaling pathways involved in cell proliferation control, apoptosis, migration, and differentiation. They also appear to influence steroid hormone signaling through transcriptional networks involving steroid hormone receptors and members of the nuclear receptor family of transcription factors. Our study aims to evaluate the potential prognostic role of KLF5, KLF9, and KLF11 in endometrial cancer, and their correlation with hormonal receptor status and cellular proliferation.

Lipoblasts in spindle cell and pleomorphic lipomas: a close scrutiny.

The presence and frequency of lipoblasts (LPB) in spindle cell lipomas (SCL) and pleomorphic lipomas (PL) has never been studied in detail on a histologically, immunohistochemically and molecular genetically validated set of tumors. The authors investigated this feature by reviewing 91 cases of SCL and 38 PL. When more than 3 unequivocal LPB were found, the case was regarded as positive for the presence of LPB.

[Effect of bovine hypodermosis on various health indicators of milk in first-calvers].

The effect of the last developmental phase of the warble fly (Hypoderma bovis de Greer) larvas was studied as exerted on some health indices of milk in 20 experimental (treated) and 18 control (untreated) first-calvers of the Pinzgau breed at two localities of an area affected by bovine hypodermosis in the period from May to June, 1975. The preparation Hypocid, at a dose of 15 ml per 100 kg of body weight, was applied externally in the lumbosacral region to the experimental animals in November, 1974. Throughout the experimental period (61 days) the milk was repeatedly examined bacteriologically and cytologically, the content of chlorides and the milk electric conductivity were determined.

[Effect of hypodermyiasis in cattle on milk-production indicators in 1st-calvers].

We investigated the effect of hypodermosis on the quantitative and some qualitative indicators of milk from 20 experimental and 18 control first-calvers of the Pinzgau cattle breed. The experiment took place at two experimental localities in mountainous pastures of the Central-Slovakian region. In the experimental animals, treated with Hypocid, the production of milk per dairy cow increased on an average by 115.

[Milking without additional hand stripping and health status of the mammary gland].

A field trial was performed in two half-sib first-calver groups of the Bohemiam Spotted breed. Each group included thirteen animals, studied for the effect of milking without additional hand stripping on the health condition of the mammary gland for a period of one lactation. The indices of an udder health condition were not affected at an appreciable level of statistical significance (the clinical and bacteriological picture, the positivity of the Mastitis test - NK, the content of milk cellular elements, milk chloride ion content, lactose content, and the value of the chlorine-sugar number.

[Effect of various factors on the electric conductivity of mixed milk].

The authors evaluated the method of the determination of the electric conductivity of purchased milk for the estimation of the hygienic aspects of milk quality and for mass diagnosis of the inflammatory diseases of dairy cow mammary glands. The variability coefficient of duplicates varied from 1.37 to 3.

[Influence of some factors on the electric conductivity of mixed milk].

The authors evaluated the method of the determination of the electric conductivity of purchased milk for the estimation of the hygienic aspects of mlik quality and for mass diagnosis of the inflammatory diseases of dairy cow mammary glands. The variability coefficient of duplicates varied from 1.37 to 3.
