34-21.09, P = 0.017). CONCLUSION This study suggests the activity of plucking of tea leaves by women is associated with LBW of babies and decreased placental weight. Particularly, if mothers worked continuously in the tea garden during 9 months of pregnancy, it also increased the risk of delivering LBW babies. This exploratory study provides an important platform for further prospective studies, which could be focused on the potential consequences of maternal occupational exposures during pregnancy on fetal development. © 2020 Japan Society of Obstetrics and Gynecology."Deep learning" is causing rapid technological changes in many fields of science, and conjectures about its potential for transforming everyone's work and lives is a matter of great debate. Unfortunately, it is all too easy to apply it as a "black box" tool with little consideration of its potential limitations, especially when the data it is being applied to is less than perfect. In this Perspective, I try to put deep learning into a broader mechanistic and historical context by showing how it relates to older forms of artificial intelligence; by providing a general explanation of how it operates; and by exploring some of the challenges involved in its implementation. Examples wherein it has been applied to pest management problems are provided to illustrate how the technology works and the challenges deep learning faces. At least in the near term, its biggest impact on agrochemical development seems likely to come in automating the tedious work involved in assessing agrochemical efficacy, but getting there will require major investments in building large, well-curated data sets to work from and in providing the expertise required to assess the resulting model predictions in real-world scenarios. Deep learning may also come to complement the machine learning methodologies already available for use in pesticide discovery and development, but it seems unlikely to supplant them.

At the end of the experiment, proliferation, viability, migration, and ultrastructural changes were monitored. Glutathione at the doses of 0.5 to 10.0 mg/mL reduced the viability of melanocytes significantly as compared to the control (P  less then  .05). Glutathione significantly reduced the proliferation of melanocytes at the doses of 0.5 to 10.0 mg/mL as compared to the control (P  less then  .001). Glutathione at 0.5 to 10.0 mg/mL significantly reduced the migration of melanocytes as compared to the control (P  less then  .001). The percentage of mature melanosomes was 53.43% in control and 50.58%, 41.83%, 33.4%, and 8.95% in 0.1, 0.5, 1.0, and 5.0 mg/mL glutathione exposed cells, respectively. This reduction in the number of mature melanosomes was statistically significant as compared to the control. However, no cytotoxic effects were recognized by electron micrographs. These results encourage the potential implementation of glutathione as a skin-lightening agent. However, this study is limited by cell culture and ultrastructural. It should therefore be expanded in the future to include patients with pigmentary disorders. © 2020 Wiley Periodicals, Inc.Alterations in vascular networks, including angiogenesis and capillary regression, play key roles in disease, wound healing, and development. The spatial structures of blood vessels can be captured through imaging, but effective characterization of network architecture requires both metrics for quantification and software to carry out the analysis in a high-throughput and unbiased fashion. We present REAVER (Rapid Editable Analysis of Vessel Elements Routine), an open-source tool that researchers can use to analyze high-resolution 2D fluorescent images of blood vessel networks, and assess its performance compared to alternative image analysis programs. Using a dataset of manually analyzed images from a variety of murine tissues as a ground-truth, REAVER exhibited the highest accuracy and precision for all vessel architecture metrics quantified, including vessel length density, vessel area fraction, mean vessel diameter, and branchpoint count, along with the highest pixel-by-pixel accuracy for the segmentation of the blood vessel network. In instances where REAVER's automated segmentation is inaccurate, we show that combining manual curation with automated analysis improves the accuracy of vessel architecture metrics. REAVER can be used to quantify differences in blood vessel architectures, making it useful in experiments designed to evaluate the effects of different external perturbations (e.g. drugs or disease states).

An abdominal aortic aneurysm (AAA) may result in a life-threatening rupture of the aortic wall. The trigger for AAA formation remains unknown, but the vascular adventitia of advanced AAAs is infiltrated by various leukocytes, indicating that the pathogenesis may involve inflammation. METHODS In Sweden, all 65-year-old men are invited to an ultrasound examination for detection of AAA. At the Gothenburg screening site, 16 256 men were examined in 2013-2017, 1.2% of whom had an AAA (diameter of the infrarenal aorta ≥30 mm). All men with AAA at screening as well as a randomized selection of AAA-free screened men were invited to participate in a case-control study. RESULTS The median diameter of AAAs was 33 mm. Men with an AAA (n = 151) had a higher frequency of smoking, hypertension and statin use than controls (n = 224). Blood levels of neutrophils, lymphocytes, monocytes and basophils were higher in individuals with an AAA, but eosinophil count did not differ from controls.
