Randomness in Cancer Breakpoint Prediction.

J Comput Biol 2021 Jun 15. Epub 2021 Jun 15.

Laboratory of Bioinformatics, Faculty of Computer Science, National Research University Higher School of Economics, Moscow, Russia.

Cancer genomes are susceptible to multiple rearrangements by deleting, inserting, and translocating genomic regions. Recently, the problem of finding determinants of breakpoint formations was approached with machine learning methods; however, unlike cancer point mutations, breakpoint prediction appeared to be a more difficult task, and various machine learning models did not achieve high prediction power often slightly exceeding the threshold of random guessing. This raised the question of whether the breakpoints are random noise in cancer mutagenesis or there exist determinants in structural mutagenesis. Read More

The Ability of Probiotic Lactobacillus Strains in Removal of Benzo[a]pyrene: a Response Surface Methodology Study.

Probiotics Antimicrob Proteins 2021 Jun 15. Epub 2021 Jun 15.

Department of Food Science and Technology, Faculty of Nutrition Sciences and Food Technology, National Nutrition and Food Technology Research Institute, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

In this study, the ability of various lactic acid bacteria was assessed in removing benzo[a]pyrene (BaP) from contaminated phosphate buffer saline (PBS). Response surface methodology (RSM) was performed using Box-Behnken design to investigate the effect of four independent variables including pH (5-7), incubation time (1-24 h), cell density (10-10 cfu/mL), and initial BaP concentration (5-15 mg/kg) at three levels to evaluate in vitro removal of BaP as response. The results showed that all the tested strains were able to remove BaP from PBS and this reduction was entirely strain-specific. Read More

The Fluorescent Dye 1,6-Diphenyl-1,3,5-hexatriene Binds to Amyloid Fibrils Formed by Human Amylin and Provides a New Probe of Amylin Amyloid Kinetics.

Biochemistry 2021 Jun 15. Epub 2021 Jun 15.

Graduate Program in Biochemistry and Structural Biology, Stony Brook University, Stony Brook, New York 11794, United States.

The fluorescent dye 1,6-diphenyl-1,3,5-hexatriene (DPH) is widely used as a probe of membrane order. We show that DPH also interacts with amyloid fibrils formed by human amylin (h-amylin, also known as islet amyloid polypeptide) in solution, and this results in a 100-fold increase in DPH fluorescence for a sample of 20 μM h-amylin and 0.25 μM DPH.

The effect of source claims on statement believability and speaker accountability.

Mem Cognit 2021 Jun 14. Epub 2021 Jun 14.

Department of Cognitive Science, Central European University, Budapest, Hungary.

What is the effect of source claims (such as "I saw it" or "Somebody told me") on the believability of statements, and what mechanisms are responsible for this effect? In this study, we tested the idea that source claims impact statement believability by modulating the extent to which a speaker is perceived to be committed to (and thereby accountable for) the truth of her assertion. Across three experiments, we presented participants with statements associated with different source claims, asked them to judge how much they believed the statements, and how much the speaker was responsible if the statement turned out to be false. We found that (1) statement believability predicted speaker accountability independently of a statement's perceived prior likelihood or associated source claim; (2) being associated with a claim to first-hand ("I saw that .

Rhizosphere Bacterial Networks, but Not Diversity, Are Impacted by Pea-Wheat Intercropping.

Front Microbiol 2021 28;12:674556. Epub 2021 May 28.

Agroécologie, AgroSup Dijon, INRAE, Université de Bourgogne - Université de Bourgogne Franche-Comté, Dijon, France.

Plant-plant associations, notably cereal-legume intercropping, have been proposed in agroecology to better value resources and thus reduce the use of chemical inputs in agriculture. Wheat-pea intercropping allows to decreasing the use of nitrogen fertilization through ecological processes such as niche complementarity and facilitation. Rhizosphere microbial communities may account for these processes, since they play a major role in biogeochemical cycles and impact plant nutrition. Read More

A genome-wide portrait of pervasive drug contaminants.

Sci Rep 2021 Jun 14;11(1):12487. Epub 2021 Jun 14.

Genome Science & Technology Graduate Program, University of British Columbia, Vancouver, Canada.

Using a validated yeast chemogenomic platform, we characterized the genome-wide effects of several pharmaceutical contaminants, including three N-nitrosamines (NDMA, NDEA and NMBA), two related compounds (DMF and 4NQO) and several of their metabolites. A collection of 4800 non-essential homozygous diploid yeast deletion strains were screened in parallel and the strain abundance was quantified by barcode sequencing. These data were used to rank deletion strains representing genes required for resistance to the compounds to delineate affected cellular pathways and to visualize the global cellular effects of these toxins in an easy-to-use searchable database.

Deep ensemble multitask classification of emergency medical call incidents combining multimodal data improves emergency medical dispatch.

Artif Intell Med 2021 Jul 13;117:102088. Epub 2021 May 13.

Biomedical Data Science Laboratory (BDSLab), Instituto de Aplicaciones de las Tecnologías de la Información y de las Comunicaciones Avanzadas (ITACA), Universitat Politècnica de València (UPV), Camino de Vera s/n, 46022 Valencia, Spain.

The objective of this work was to develop a predictive model to aid non-clinical dispatchers to classify emergency medical call incidents by their life-threatening level (yes/no), admissible response delay (undelayable, minutes, hours, days) and emergency system jurisdiction (emergency system/primary care) in real time. We used a total of 1 244 624 independent incidents from the Valencian emergency medical dispatch service in Spain, compiled in retrospective from 2009 to 2012, including clinical features, demographics, circumstantial factors and free text dispatcher observations. Based on them, we designed and developed DeepEMC, a deep ensemble multitask model integrating four subnetworks: three specialized to context, clinical and text data, respectively, and another to ensemble the former.
