Sharp ended α-Fe core microwire covered with PrDyFeCoB amorphous shell with enhanced stray magnetic field is proposed for magnetic tweezers, stepwise switchable in external homogeneous magnetic field. Four stable magnetic states of the microwire, controlled by external magnetic field, were determined by magneto-optical Kerr effect (MOKE) microscopy. Distribution of the stray field near the microwire tip was plotted by magneto-optical indicator film (MOIF) technique. Large gradient of the stray magnetic field in the vicinity of the microwire tip is quite enough to provide magnetic force ~ 2000 pN, well enough for capturing of the PrDyFeCoB microparticle. Significance of the obtained results is in switching of the focused stray field of the microwire under external homogeneous magnetic field. This provides simple way of stepwise attaching-detaching of microparticles without electromagnetic micro coils.

This dataset archives time lapse images of fluorescent actin in two types of cells (epithelial MCF10A and neutrophil-like HL60) plated on flat or nanoridged surfaces. These images show that nanoridged surfaces are capable of reproducibly guiding actin waves (esotaxis) in both cell types. This dataset is further described in Lee, Campanello, et al. 2020 (https://www.molbiolcell.org/doi/abs/10.1091/mbc.E19-11-0614), the first reporting of this data in the peer-reviewed literature. This publication should be referenced for details on the context and analysis of this data. The included README.TXT provides a more detailed description of the images and methodology.

Collection of these images was supported by AFOSR grant number FA9550-16-1-0052 as well as by NCI/NIH Award Number T32CA154274 (RML).

Purpose of the present study was to investigate the association of NKT cells with key ovarian markers (OC) - CA125 in serum. The study describes the assessment of iNKT cells in peripheral blood and tissue of benign and borderline ovarian tumors (BOTs) and in the advanced-stage ovarian cancer. The study group consisted of 25 women with benign ovarian tumors, 11 women with BOTs, and 24 women with primary advanced-stage ovarian cancers. The control group was composed of 20 patients without the ovarian pathology. The percentages of iNKT lymphocytes in the peripheral blood and tissue specimens were assessed by a flow cytometry. Significant differences in the percentage of iNKT+/CD3+ of CD3+ lymphocytes, iNKT+/CD3+/CD161+ among CD3+ and iNKT+/CD3+/CD161+ among CD3+/iNKT+ between the control group and patients with ovarian tumors in the peripheral blood and tumor tissue were found. Significant correlations were noted between the percentage of lymphocytes iNKT+/CD3+/CD161+ of CD3+/iNKT cells in blood and in tumor tissue of both benign and malignant tumors. In the OC group, neither the percentage of iNKT cells in the blood (P=0.07), nor the intra-tumor NKT-cell infiltration (P=0.5) were found to constitute independent prognostic factors for the follow-up. An increased percentage of iNKT cells was observed in benign ovarian tumors compared to OCs. In ovarian cancer patients, a higher percentage of iNKT cells in tumor tissue was present in comparison to that observed in the patient’s blood. Moreover, a correlation between the serum marker CA125 and NKT cells from the ovarian tissue of patients with ovarian cancer was detected. The current paper, for the first time, showed the negative association between concentration of CA125 in serum and NKT lymphocyte from ovarian tissue. Presented findings underscore new aspects of the iNKT cells involvement in the ovarian cancer development. Inflammatory process in ovarian cancer tissue and possibility of endothelial immune cells to infilitrate, could be causes small amount of NKT cells in microenviroment and increased CA125 marker in circulation.

This dataset represents a high resolution urban land cover classification map across the southern California Air Basin (SoCAB) with a spatial resolution of 60 cm in urban regions and 10 m in non-urban regions. This map was developed to support NASA JPL-based urban biospheric CO2 modeling in Los Angeles, CA. Land cover classification was derived from a novel fusion of Sentinel-2 (10-60 m x 10-60 m) and 2016 NAIP (60 cm x 60 cm) imagery and provides identification of impervious surface, non-photosynthetic vegetation, shrub, tree, grass, pools and lakes. Land Cover Classes in .tif file: 0: Impervious surface 1: Tree (mixed evergreen/deciduous) 2: Grass (assumed irrigated) 3: Shrub 4: Non-photosynthetic vegetation 5: Water (masked using MNDWI/NDWI) A portion of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

Termites are present in different environments, they perform the functions of cycling organic compounds in the soil and decomposing organic matter. Through this behavior, some species can generate great economic losses in the agricultural environment for some cultures. Such insects can communicate through semi-chemical and vibroacystic signals. These signals transmit different types of messages. The vibroacoustic signals occur when there is interaction between the generated vibrating waves, which can, consequently, generate understandable optical interference phenomena when light is applied, one of these phenomena that can be understood is the dynamic biospeckle. It is proposed in this research, to evaluate the bioactivity of the termite Nasutitermes corniger (Insecta: Isoptera) during the walk using the optical phenomenon of interference Biospeckle. Termites were collected in colonies present on the University campus of the Federal University of Sergipe-UFS. 25 individuals were randomly selected, distributed in 5 groups. Such individuals will be submitted to the simulation activity of walking in arenas created using Petri dishes (14 x 1.5 cm) which were exposed to laser light, during the movement of the insect videos were captured which were later processed using the Generalized Differences Method and the Moment of Inertia. It was possible to detect the areas of walking and of greater activities caused naturally by the groups of Nasutitermes corniger present in the arenas, as well as the method of MI showed to be significantly different when analyzed before and during the walking. Thus, it is possible to analyze the walking activity of Nasutitermes corniger by means of dynamic biospeckle in different types of light, which can be applied as a possible tool to evaluate the termite's bioactivity.
