Changes in snail and SRF expression in the kidneys of diabetic rats during ageing.

Background: Diabetic nephropathy is a progressive condition which develops for many years. We analyzed expression of Snail and serum response factor (SRF), epithelial-mesenchymal transition (EMT) regulatory transcription factors with a key role in renal fibrosis, in different renal areas of diabetic rats during ageing.

Methods: Male Sprague-Dawley rats were treated with 55 mg/kg streptozotocin (model of type 1 diabetes mellitus; DM group) or citrate buffer (control).

Chemical Composition and Acaricidal Activity of the Essential Oils of Some Plant Species of and against the Vector of Tropical Bovine Theileriosis: (syn. ).

The present study aimed to investigate the acaricidal properties of six essential oils. They were extracted from some plant species ( and ) using the technique of hydrodistillation with the Clevenger apparatus. The chemical compositions of the essential oils under study were determined by gas chromatography-mass spectrometer (GC-MS).

Antifungal activity of essential oils extract from Origanum floribundum Munby, Rosmarinus officinalis L. and Thymus ciliatus Desf. against Candida albicans isolated from bovine clinical mastitis.

Objective: The aim of this study is to limit the antibiotic use in mastitis treatment and to find other alternatives. The antifungal activity of the essential oils from Origanum floribundum Munby., Rosmarinus officinalis L.

Optical screw-wrench for microassembly.

For future micro- and nanotechnologies, the manufacturing of miniaturized, functionalized, and integrated devices is indispensable. In this paper, an assembly technique based on a bottom-up strategy that enables the manufacturing of complex microsystems using only optical methods is presented. A screw connection is transferred to the micrometer range and used to assemble screw- and nut-shaped microcomponents.
