864, mean error=8.25%] than inexperienced pathologists (ICC=0.807, mean error=11.0%) in visual assessment. Moreover, with reference cards, inexperienced pathologists (ICC=0.836, mean error=10.7%) and experienced pathologists (ICC=0.875, mean error=7.56%) improved their reproducibility and accuracy. Finally, both experienced pathologists (ICC=0.937, mean error=4.36%) and inexperienced pathologists (ICC=0.923, mean error=4.71%) improved the reproducibility and accuracy significantly with the AI-empowered microscope.
The AI-empowered microscope allows seamless integration of the AI solution into the clinical workflow, and helps pathologists to obtain higher consistency and accuracy for Ki67 assessment.

The combination of near-infrared (NIR) spectroscopy and chemometrics can be used to group or discriminate soils based on spectral response. In this study, we conducted discrimination and classification analyses on soils managed with different sources of fertilization and plant species grown in organic and conventional farming systems.
Principal component analysis explained 96% (PC1) and 3% (PC2) of the data variability and separated the soil samples of organic and conventional management systems. selleckchem The wavenumbers that contributed most to the separation of the management systems were in the range of 3600 and 7300 cm
, especially the absorption peaks of 3700 and 4600 cm
(characteristic of CH and NH combinations), and 5200 and 7000 cm
(typical of OH combinations). Machine learning analysis using k-nearest neighbor and random forest algorithms was efficient in classifying soil samples according to management system with an accuracy of 97.8% and can therefore be used for future classification studies.
Based on the results, we strongly recommend the use of NIR spectroscopy associated with chemometrics for discriminating soils grown with Malus domestica, Musa spp., Oryza sativa and Solanum tuberosum L. under organic and conventional management systems through spectral response. © 2021 Society of Chemical Industry.

This glucocorticoid effect on the consolidation process also requires central noradrenergic neurotransmission. The intracellular pathways of these two stress mediators converge on two transcription factors the glucocorticoid receptor (GR) and phosphorylated cAMP response element-binding protein (pCREB). We therefore investigated, in male rats, whether glucocorticoid effects on memory are associated with genomic interactions between the GR and pCREB in the hippocampus. In a two-by-two design, object exploration training or no training was combined with post-training administration of a memory-enhancing dose of corticosterone or vehicle. Genomic effects were studied by chromatin immunoprecipitation followed by sequencing (ChIP-seq) of GR and pCREB 45 min after training and transcriptome analysis after 3 hr. Corticosterone administration induced differential GR DNA-binding and regulation of target genes within the hippocampus, largely independent of training. Training alone did not result in long-term memory nor did it affect GR or pCREB DNA-binding and gene expression. No strong evidence was found for an interaction between GR and pCREB. Combination of the GR DNA-binding and transcriptome data identified a set of novel, likely direct, GR target genes that are candidate mediators of corticosterone effects on memory consolidation. Cell-specific expression of the identified target genes using single-cell expression data suggests that the effects of corticosterone reflect in part non-neuronal cells. Together, our data identified new GR targets associated with memory consolidation that reflect effects in both neuronal and non-neuronal cells.Hair-fin anchovy (Setipinna tenuifilis) is an economically important fish distributed in the West Indian Ocean and the Northwest Pacific Ocean. In this study, 154 individuals in eight populations of S. tenuifilis were sequenced and 850 million raw reads were obtained using restriction site-associated DNA sequencing (RAD-seq). First, we identified 14 012 044 hypothetical SNP markers. A dataset of 199 903 high-quality SNPs was collected after further screening. These SNPs have a strong ability to test the genetic diversity between the eight populations. The differentiation and genetic law between samples were explored based on SNPs in populations of S. tenuifilis. The results of this study will provide data for protecting the genetic resources of the species.Urea cycle disorders (UCDs) are inherited metabolic disorders with impaired nitrogen detoxification caused by defects in urea cycle enzymes. They often manifest with hyperammonemic attacks resulting in significant morbidity or death. We performed a nationwide questionnaire-based study between January 2000 and March 2018 to document all UCDs in Japan, including diagnoses, treatments, and outcomes. A total of 229 patients with UCDs were enrolled in this study 73 males and 53 females with ornithine transcarbamylase deficiency (OTCD), 33 patients with carbamoylphosphate synthetase 1 deficiency, 48 with argininosuccinate synthetase deficiency, 14 with argininosuccinate lyase deficiency, and 8 with arginase deficiency. Survival rates at 20 years of age of male and female patients with late-onset OTCD were 100% and 97.7%, respectively. Blood ammonia levels and time of onset had a significant impact on the neurodevelopmental outcome (P less then .001 and P = .028, respectively). Hemodialysis and liver transplantation did not prevent poor neurodevelopmental outcomes.
