Deep neural net tracking of human pluripotent stem cells reveals intrinsic behaviors directing morphogenesis.

Stem Cell Reports 2021 May;16(5):1317-1330

Gladstone Institutes, San Francisco, CA, USA; Department of Bioengineering and Therapeutic Sciences, University of California, San Francisco, San Francisco, CA, USA. Electronic address:

Lineage tracing is a powerful tool in developmental biology to interrogate the evolution of tissue formation, but the dense, three-dimensional nature of tissue limits the assembly of individual cell trajectories into complete reconstructions of development. Human induced pluripotent stem cells (hiPSCs) can recapitulate aspects of developmental processes, providing an in vitro platform to assess the dynamic collective behaviors directing tissue morphogenesis. Here, we trained an ensemble of neural networks to track individual hiPSCs in time-lapse microscopy, generating longitudinal measures of cell and cellular neighborhood properties on timescales from minutes to days.

Effects of the presence of a dog on the psychic content expression of a stuttering person: case report.

Codas 2021 3;33(2):e20190267. Epub 2021 May 3.

Programa de Estudos Pós-graduados em Fonoaudiologia, Faculdade de Ciências Humanas e da Saúde, Pontifícia Universidade Católica de São Paulo - PUC-SP - São Paulo (SP), Brasil.

Stuttering has negative impacts on an individual's quality of life and is associated with higher risk of development of social and psychological problems. From this perspective, despite the diversity of etiological hypotheses for and treatments of stuttering, the interface between psychology and speech therapy in the approach to the biopsychic aspects involved in this clinical scenario stands out. Recent research indicates that the presence, specifically of dogs, can assist patients in symbolic elaboration of psychic content. Read More

Characterization of the volume fraction of soft deformable microgels by means of small-angle neutron scattering with contrast variation.

Andrea Scotti

Soft Matter 2021 May 12. Epub 2021 May 12.

Institute of Physical Chemistry, RWTH Aachen University, 52056, Aachen, Germany.

The volume occupied by colloids in a suspension - namely the volume fraction - is the thermodynamic variable that determines the phase behavior of these systems. While for hard incompressible spheres this quantity is well defined, for soft compressible colloids such as microgels - polymeric crosslinked networks swollen in a good solvent - the determination of the real volume occupied by these particles in solution is particularly challenging. This fact depends on two aspects: first the surface and, therefore, the volume of the microgels is hard to define properly given their external fuzziness; second, microgels can osmotically deswell, deform or interpenetrate their neighbors, i.

State of the Art in Radiolabeling of Antibodies with Common and Uncommon Radiometals for Preclinical and Clinical Immuno-PET.

Bioconjug Chem 2021 May 11. Epub 2021 May 11.

Amsterdam UMC, Vrije Universiteit Amsterdam, Radiology & Nuclear Medicine, Cancer Center Amsterdam, De Boelelaan 1117, Amsterdam 1081 HV, The Netherlands.

Inert and stable radiolabeling of monoclonal antibodies (mAb), antibody fragments, or antibody mimetics with radiometals is a prerequisite for immuno-PET. While radiolabeling is preferably fast, mild, efficient, and reproducible, especially when applied for human use in a current Good Manufacturing Practice compliant way, it is crucial that the obtained radioimmunoconjugate is stable and shows preserved immunoreactivity and behavior. Radiometals and chelators have extensively been evaluated to come to the most ideal radiometal-chelator pair for each type of antibody derivative. Read More

Target Enhancement or Distractor Suppression? Functionally Distinct Alpha Oscillations form the Basis of Attention.

Eur J Neurosci 2021 May 11. Epub 2021 May 11.

Department of Psychology, University of Lübeck, Lübeck, Germany.

Recent advances in attention research have been propelled by the debate on target enhancement versus distractor suppression. A predominant neural correlate of attention is the modulation of alpha oscillatory power (~10 Hz), which signifies shifts of attention in time, space, and between sensory modalities. However, the underspecified functional role of alpha oscillations limits the progress of tracking down the neuro-cognitive basis of attention. Read More

Using strontium isotopes to determine philopatry and dispersal in primates: a case study from Kibale National Park.

R Soc Open Sci 2021 Feb 10;8(2):200760. Epub 2021 Feb 10.

Department of Anthropology, University of New Mexico, Albuquerque, NM, 87111, USA.

Strontium isotope ratios (Sr/Sr) allow researchers to track changes in mobility throughout an animal's life and could theoretically be used to reconstruct sex-biases in philopatry and dispersal patterns in primates. Dispersal patterns are a life-history variable that correlate with numerous aspects of behaviour and socio-ecology that are elusive in the fossil record. The present study demonstrates that the standard archaeological method used to differentiate between 'local' and 'non-local' individuals, which involves comparing faunal isotopic ratios with environmental isotopic minima and maxima, is not always reliable; aspects of primate behaviour, local environments, geologic heterogeneity and the availability of detailed geologic maps may compromise its utility in certain situations.

A sex-dependent role for the prelimbic cortex in impulsive action both before and following early cocaine abstinence.

Neuropsychopharmacology 2021 May 10. Epub 2021 May 10.

Department of Psychology & Neuroscience, University of North Carolina, Chapel Hill, NC, USA.

Although impulsive action is strongly associated with addiction, the neural underpinnings of this relationship and how they are influenced by sex have not been well characterized. Here, we used a titrating reaction time task to assess differences in impulsive action in male and female Long Evans rats both before and after short (4-6 days) or long (25-27 days) abstinence from 2 weeks of cocaine or water/saline self-administration (6 h daily access). Neural activity in the prelimbic cortex (PrL) and nucleus accumbens (NAc) core was assessed at each time point. Read More

Numerical models of spinal cord trauma: The effect of cerebrospinal fluid pressure and epidural fat on the results.

J Neurotrauma 2021 May 11. Epub 2021 May 11.

Tel Aviv University, 26745, Ramat Aviv, Tel Aviv, Tel Aviv, Israel, 69978;

Spinal cord injury (SCI) is commonly caused by traumatic mechanical damage. While numerical models can help predicting the mechanics of SCI without putting the subjects in danger, previous studies did not focus on alternations in the cerebrospinal fluid (CSF) pressure and did not account for the presence of epidural fat. This study aims to numerically compare the mechanical behavior of human spine when subjected to contusion and burst fracture with varying CSF pressure, either normal or elevated pressure that represent intracranial hypertension.

Hydrogen Bonds between Ions of Opposite and Like Charge in Hydroxyl-Functionalized Ionic Liquids: an Exhaustive Examination of the Interplay between Global and Local Motions and Intermolecular Hydrogen Bond Lifetimes and Kinetics.

J Phys Chem B 2021 May 11. Epub 2021 May 11.

Institut für Chemie, Abteilung Physikalische und Theoretische Chemie, Universität Rostock, Albert-Einstein-Str. 21, D-18059 Rostock, Germany.

Hydroxyl-functionalized ionic liquids (ILs) represent a new interesting class of ILs where hydrogen bonds (HBs) play an important role: here, "typical" HBs between cations and anions (ca) are competing with "atypical" HBs connecting pairs of cations (cc). We study the equilibrium and kinetics of (cc) and (ca) HBs in 1-(-hydroxyalkyl)-pyridinium bis(trifluoromethlysulfonyl)imide [HOCPy][NTf] ILs by means of molecular dynamics simulations. (cc) HBs are found to be between 0. Read More
