TL;DR: Significant changes in gene expression by the Ishikawa cell line were detected after treatments with E2, P4, TAM, and RU486, and transcriptome data provide valuable insight into potential biomarkers related to endometrial receptivity, and facilitate an understanding of the molecular changes that take place in the endometrium in the early stages of breast cancer treatment and contraception usage.
Abstract: Background Estrogen (E2) and progesterone (P4) are key players in the maturation of the human endometrium. The corresponding steroid hormone modulators, tamoxifen (TAM) and mifepristone (RU486) are widely used in breast cancer therapy and for contraception purposes, respectively.

TL;DR: Hessian matrix-based algorithms to retrieve the orientation of individual fibres out of steel fibre reinforced cementitious composites samples scanned with an X-ray computed tomography scanner are presented.
Abstract: One of the most important factors to determine the mechanical properties of a fibre composite material is the orientation of the fibres in the matrix. This paper presents Hessian matrix-based algorithms to retrieve the orientation of individual fibres out of steel fibre reinforced cementitious composites samples scanned with an X-ray computed tomography scanner. The software implemented with the algorithms includes a massive data filtering component to remove noise from the data-sets and prepare them correctly for the analysis. Due to its short computational times and limited need for user intervention, the software is able to process and analyse large batches of data in short periods and provide results in a variety of visual and numerical formats. The application and comparison of these algorithms lead to further insight into the material behaviour. In contrast to the usual assumption that the fibres act only along their main axis, it is shown that the contribution of hooked-end fibres in other directions may be noticeable. This means that fibres, depending on their shape, should act as orthotropic inclusions. The methods can be used by research laboratories and companies on an everyday basis to obtain fibre orientations from samples, which in turn can be used in research, to study stress–strain behaviour, as input to constitutive models or for quality assurance.

TL;DR: In this paper, the basic features of the wave climate in the Southwestern Baltic Sea (such as the average and typical wave conditions, frequency of occurrence of different wave parameters, variations in wave heights from weekly to decadal scales) are established based on waverider measurements at the Darss Sill in 1991-2010.
Abstract: . The basic features of the wave climate in the Southwestern Baltic Sea (such as the average and typical wave conditions, frequency of occurrence of different wave parameters, variations in wave heights from weekly to decadal scales) are established based on waverider measurements at the Darss Sill in 1991–2010. The measured climate is compared with two numerical simulations with the WAM wave model driven by downscaled reanalysis of wind fields for 1958–2002 and by adjusted geostrophic winds for 1970–2007. The wave climate in this region is typical for semi-enclosed basins of the Baltic Sea. The maximum wave heights are about half of those in the Baltic Proper. The maximum recorded significant wave height HS =4.46 m occurred on 3 November 1995. The wave height exhibits no long-term trend but reveals modest interannual (about 12 % of the long-term mean of 0.76 m) and substantial seasonal variation. The wave periods are mostly concentrated in a narrow range of 2.6–4 s. Their distribution is almost constant over decades. The role of remote swell is very small.

TL;DR: Factors such as doxycycline's ability to form complexes with ferric iron and the ability of complexes to participate in a reductive pathway should be considered at a technological level in process optimization, with chemistry based on iron ion catalysis to enhance the doxy cycline oxidative pathway.

TL;DR: Lab-on-chip systems as mentioned in this paper are a class of miniaturized analytical devices that integrate fluidics, electronics and various sensorics, which are capable of analysing biochemical liquid samples, like solutions of metabolites, macromolecules, proteins, nucleic acids, or cells and viruses.
Abstract: Lab-on-chip systems are a class of miniaturized analytical devices that integrate fluidics, electronics and various sensorics. They are capable of analysing biochemical liquid samples, like solutions of metabolites, macromolecules, proteins, nucleic acids, or cells and viruses. Supple- mentary to their measuring capabilities, the lab-on-chip devices facilitate fluidic transportation, sorting, mixing, or separation of liquid samples. A type of lab-on-chip devices, named biochip, is devoted specifically to genomic, proteomic and pharmaceutical tests. The significance of such miniaturized devices lies in their potentiality of automating laboratory procedures, which highly reduces the time of biomedical tests and laboratory work. This review summarizes numerous fabrication methods and procedures for producing lab-on-chip devices and also envisages future evolution.
