Data from: Abundance-dependent effects of neighborhood dissimilarity and growth rank reversal in a Neotropical forest

Yuxin Chen, María Natalia Umaña, María Uriarte & Shixiao Yu
Why tropical forests harbor an exceptional number of species with striking differences in abundances remains an open question. We propose a theoretical framework to address this question in which rare species may have different extirpation risks depending on species ranks in tree growth and sensitivities to neighborhood interactions. To evaluate the framework, we studied tree growth and its responses to neighborhood dissimilarity (ND) in traits and phylogeny for 146 species in a Neotropical forest. We...

Data from: Trends in anesthesiology research: a machine learning approach to theme discovery and summarization

Alexander Rusanov, Riccardo Miotto & Chunhua Weng
Objectives: Traditionally, summarization of research themes and trends within a given discipline was accomplished by manual review of scientific works in the field. However, with the ushering in of the age of “big data”, new methods for discovery of such information become necessary as traditional techniques become increasingly difficult to apply due to the exponential growth of document repositories. Our objectives are to develop a pipeline for unsupervised theme extraction and summarization of thematic trends...

Genetic Adaptation in New York City Rats

Arbel Harpak, Nandita Garud, Noah Rosenberg, Dmitri Petrov, Pleuni Pennings & Jason Munshi-South
Brown rats (Rattus norvegicus) thrive in urban environments by navigating the anthropocentric environment and taking advantage of human resources and by-products. From the human perspective, rats are a chronic problem that causes billions of dollars in damage to agriculture, health and infrastructure. Did genetic adaptation play a role in the spread of rats in cities? To approach this question, we collected whole-genome sequences from 29 brown rats from New York City (NYC) and scanned for...

Online since 1997, CIAO has grown to encompass both grey literature and published materials from over 200 contributing institutions. Currently the database contains over 10,000 papers and, as with anything of this magnitude, the challenge is not only continued growth in terms of content aggregation but also achieving successful user experiences and wider integration with other services. Our metadata...

Statistical data from: Cholinergic modulation of hippocampally mediated attention and perception

Nicholas Ruiz, Monica Thieu & Mariam Aly
Attention to the relations between visual features modulates hippocampal representations. Moreover, hippocampal damage impairs discrimination of spatial relations. We explore a mechanism by which this might occur: modulation by the acetylcholine system. Acetylcholine enhances afferent input to the hippocampus and suppresses recurrent connections within it. This biases hippocampal processing toward environmental input, and should improve externally-oriented, hippocampally mediated attention and perception. We examined cholinergic modulation on an attention task that recruits the hippocampus. On each...

SARS-CoV-2 neutralizing antibody responses are more robust in patients with severe disease

Pengfei Wang, Lihong Liu, Manoj S. Nair, Michael T. Yin, Yang Luo, Qian Wang, Ting Yuan, Kanako Mori, Axel Guzman Solis, Masahiro Yamashita, Ankur Garg, Lawrence J. Purpura, Justin C. Laracy, Jian Yu, Leemor Joshua-Tor, Joseph Sodroski, Yaoxing Huang & David D. Ho
We studied plasma antibody responses of 35 patients about 1 month after SARS-CoV-2 infection. Titers of antibodies binding to the viral nucleocapsid and spike proteins were significantly higher in patients with severe disease. Likewise, mean antibody neutralization titers against SARS-CoV-2 pseudovirus and live virus were higher in the sicker patients, by ∼5-fold and ∼7-fold, respectively. These findings have important implications for those pursuing plasma therapy, isolation of neutralizing monoclonal antibodies, and determinants of immunity.

Data from: Daily protein prioritization and longterm nutrient balancing in a dietary generalist, the blue monkey

Maressa Takahashi & Marina Cords
Animals must make dietary choices to achieve adequate nutrient intake, however it is challenging to study in the field such nutritional strategies in wild populations. We explored the nutritional strategy of a generalist social primate, the blue monkey (Cercopithecus mitis). We hypothesized that females balance the intake of nutrients, specifically non-protein energy and available protein (hereafter, protein), both on a daily and long-term basis. When balancing was not possible, we expected subjects to prioritize constant...

Social rank modulates how environmental quality influences cooperation and conflict within animal societies

Mark Liu, Bo-Fei Chen, Dustin Rubenstein & Sheng-Feng Shen
Although dominance hierarchies occur in most societies, our understanding of how these power structures influence individual investment in cooperative and competitive behaviors remains elusive. Both conflict and cooperation in animal societies are often environmentally-regulated, yet how individuals alter their cooperative and competitive investments as environmental quality changes remains unclear. Using game theoretic modeling, we predict that individuals of all ranks will invest more in cooperation and less in social conflict in harsh environments than individuals...

Primary endpoint was the association between cCTG parameters and preeclampsia in IUGR. Secondary...

Anti-neoplastic characteristics and potential targets of calycosin against bisphenol A-related osteosarcoma: bioinformatics analysis

Qijin Pan, Ka Wu, Jiachang Tan, Yu Li, Xiao Liang & Min Su
Environmentally, bisphenol A (BPA) is a well-known pollutant caused human health risk, including osteosarcoma (OS). OS, a deadly bone neoplasia, may occur in children and adults. However, the anti-OS pharmacotherapy prescribes limitedly in clinical practice. Interestingly, previous experimental evidences indicate calycosin-exerting potential anti-OS actions. Thus, in this report, we aimed to further characterize and detail the therapeutic targets and molecular mechanisms of calycosin-anti-BPA-related OS by using network pharmacology and molecular docking analyses. In results, the...

Ziyou Tao, Chao Lu, Shuai Gao, Peng Zhang, Yuan Chen, Yuanguo Wang, Zhaoyu Yang, Kai Xiong & Yuxin Liu
Thymoma is the most common primary mass in anterior mediastinum. Although associated with low malignancy, it is often accompanied by myasthenia gravis resulting in poor prognosis. Due to the dual factors of tumor immune tolerance and autoimmune reaction, it is urgent to understand the immune status of MG with thymoma. In this study, RNA sequencing data were obtained from the TCGA and GEO cohorts to identify differentially expressed messenger RNAs and infiltrated immune cells. A...

Long-term stability of cortical ensembles

Jesús Pérez-Ortega, Tzitzitlini Alejandre-García & Rafael Yuste
Neuronal ensembles, coactive groups of neurons found in spontaneous and evoked cortical activity, are causally related to memories and perception, but it still unknown how stable or flexible they are over time. We used two-photon multiplane calcium imaging to track over weeks the activity of the same pyramidal neurons in layer 2/3 of the visual cortex from awake mice and recorded their spontaneous and visually evoked responses. Less than half of the neurons were commonly...

Pinki Mondal, Ruth DeFries, Jessica Clark, Nicole Flowerhill, , Aurélie Harou, Shauna Downs & Jessica Fanzo
Achieving and maintaining food and nutrition security is an important Sustainable Development Goal (SDG), especially in countries with largely vulnerable population with high occurrence of hunger and malnutrition. By studying a small-scale agricultural system in India, we aim to understand the current state of dietary diversity and food insecurity among the farmer communities. The study landscape has witnessed a steady rise in multiple cropping along with irrigation over the last two decades. Whether this multiple...

Prediction of bladder cancer outcome by identifying and validating a mutation-derived genomic instability-associated long noncoding RNA (lncRNA) signature

Hao Wu, Zi-Yi Zhang, Ze Zhang, Xin-Ying Xiao, Sheng-Lin Gao, Chao Lu, Li Zuo & Li-Feng Zhang
Bladder cancer is one of the most common malignant tumors worldwide. Accordingly, its incidence and mortality are high. One of the characteristics of cancer is genomic instability. New studies suggest that long non-coding RNAs (lncRNAs) play an important role in maintaining genomic instability. This study aimed to identify a genomic instability-associated lncRNA signature to predict the outcome of patients with bladder cancer. We downloaded data for bladder cancer patients from The Cancer Genome Atlas database...

Ensemble synchronization in the reassembly of Hydra's nervous system

Jonathan Lovas & Rafael Yuste
Although much is known about how the structure of the nervous system develops, it is still unclear how its functional modularity arises. A dream experiment would be to observe the entire development of a nervous system, correlating the emergence of functional units with their associated behaviors. This is possible in the cnidarian Hydra vulgaris, which, after its complete dissociation into individual cells, can reassemble itself back together into a normal animal. We used calcium imaging...

Post-processed data for: Diverse operant control of different motor cortex populations during learning

Nuria Vendrell-Llopis, Ching Fang, Albert Qü, Rui Costa & Jose Carmena
We tested two population of cortical neurons, intra-telencephalic (IT) and extra-telencephalic or pyramidal tract (PT) neurons, as direct neurons for neuroprosthetic control. We labelled different cell-classes in two groups of mice and trained them to modulate the activity of either IT or PT neurons to control a Ca-imaging based brain-machine interface (CaBMI). In addition, we used machine learning and game theory approaches to reverse-engineer the learning outcome and dissect the causal contributions of cell-class, neuronal...

Prenatal environmental conditions underlie alternative reproductive tactics that drive the formation of a mixed-kin cooperative society

Shailee Shah & Dustin Rubenstein
Although animal societies often evolve due to limited natal dispersal that results in kin clustering and facilitates cooperation among relatives, many species form cooperative groups with low kin structure. Such groups often comprise residents and immigrants of the same sex that compete for breeding opportunities. To understand how such mixed-kin societies form, we investigated the causes and fitness consequences of dispersal decisions in male cooperatively breeding superb starlings (Lamprotornis superbus) inhabiting a climatically unpredictable environment....
