Ovarian hyperstimulation syndrome is the most serious iatrogenic complication resulting from ovarian stimulation. Currently there is no clear evidence of absolute efficacy for most of standard preventive and curative methods. Recent studies indicate that human chorionic gonadotropin increases vascular endothelial growth factor, vascular endothelial cadherin and vascular permeability via endothe...

We investigate the origin of undesirable transverse cracks often observed in thin films obtained by the layer transfer technique. During this process, two crystals bonded to each other containing a weak plan produced by ion implantation are heated to let a thin layer of one of the material on the other. The level of stress imposed on the film during the heating phase due to the mismatch of ther...

The input data for DNA computing must be encoded into the form of single or double DNA strands. As complementary parts of single strands can bind together forming a double-stranded DNA sequence, one has to impose restrictions on these sets of DNA words (=languages) to prevent them from interacting in undesirable ways. We recall a list of known properties of DNA languages which are free of certa...

25 26 This article describes the development, validation and application of a rapid screening method 27 for the detection and identification of undesirable organic compounds in aquaculture products. 28 A generic sample treatment was applied without any purification or preconcentration step. After 29 extracting the samples with acetonitrile/water 80:20 (0.1% formic acid), the extracts were 30 ce...

1,4-Benzoquinones have been found to prevent olefin isomerization of a number of allylic ethers and long-chain aliphatic alkenes during ruthenium-catalyzed olefin metathesis reactions. Electron-deficient benzoquinones are the most effective additives for the prevention of olefin migration. This mild, inexpensive, and effective method to block olefin isomerization increases the synthetic utility...

Fires will become an increasingly frequent perturbation even under the conditions of mild climate zone and interfere with agricultural landscape. Fire is a natural phenomenon, depending on ecosystems, vegetation may develop contribute to occurrence spread fire. Vegetation sour cherry orchard located in climatically dry South Moravian Region, Czech Republic (CR), was evaluated. assessment perfor...
