Unilateral auditory deprivation in humans: Effects on frequency discrimination and auditory memory span in the normal ear.

Hear Res 2021 Apr 9;405:108245. Epub 2021 Apr 9.

Department of Ear, Nose and Throat, GGS Medical College and Hospital, Baba Farid University of Health Sciences, Faridkot, Punjab 151203, India.

Hearing with one ear is associated with auditory deprivation leading to cortical neuronal reorganization. Despite evidence for substantial effects of unilateral input on cortical and sub-cortical structures, the functional consequences of such alterations on human hearing is underexplored. Unilateral hearing impairment offers a unique model to study the perceptual consequences of cortical reorganization. Read More

Longitudinal self-supervised learning.

Med Image Anal 2021 Apr 4;71:102051. Epub 2021 Apr 4.

Department of Psychiatry & Behavioral Sciences, Stanford University, Stanford, CA 94305, USA; Center for Biomedical Sciences, SRI International, Menlo Park, CA 95025, USA. Electronic address:

Machine learning analysis of longitudinal neuroimaging data is typically based on supervised learning, which requires large number of ground-truth labels to be informative. As ground-truth labels are often missing or expensive to obtain in neuroscience, we avoid them in our analysis by combing factor disentanglement with self-supervised learning to identify changes and consistencies across the multiple MRIs acquired of each individual over time. Specifically, we propose a new definition of disentanglement by formulating a multivariate mapping between factors (e. Read More

Kirkwood-Buff-Derived Force Field for Peptides and Proteins: Philosophy and Development of KBFF20.

J Chem Theory Comput 2021 Apr 20. Epub 2021 Apr 20.

Department of Chemistry, Kansas State University, 213 CBC Building, 1212 Mid-Campus Drive North, Manhattan, Kansas 66506, United States.

A new classical nonpolarizable force field, KBFF20, for the simulation of peptides and proteins is presented. The force field relies heavily on the use of Kirkwood-Buff theory to provide a comparison of simulated and experimental Kirkwood-Buff integrals for solutes containing the functional groups common in proteins, thus ensuring intermolecular interactions that provide a good balance between the peptide-peptide, peptide-solvent, and solvent-solvent distributions observed in solution mixtures. In this way, it differs significantly from other biomolecular force fields. Read More

Hypnale coagulopathy: snake envenomation of a different kind.

J R Coll Physicians Edinb 2021 Mar;51(1):31-36

Alva's Health Centre, Moodabidri-574227, Karnataka, India, Email:

Hypnale hypnale is a small pit viper that is known as the hump-nosed pit viper (HNV) or 'Merrem's hump-nosed pit viper' and is endemic to Sri Lanka and the Western Ghats of South India. Previously, it was thought that this viper bite would result in mild systemic or local envenomation, however, we now know that HNV bites could cause severe systemic toxicity and mortality. The most common systemic toxicity of this viper envenomation is coagulopathy, which is known as 'Hypnale coagulopathy'. Read More

NK-Cell Biofactory as an Off-the-Shelf Cell-based Vector for Targeted In Situ Synthesis of Engineered Proteins.

Adv Biol (Weinh) 2021 Apr 19:e2000298. Epub 2021 Apr 19.

Biosciences Division SRI International, Menlo Park, CA, 94025, USA.

The NK-92MI, a fast-growing cytolytic cell line with a track record of exerting clinical efficacy, is transformed into a vector for synthesizing calibrated amounts of desired engineered proteins at our disease site, that is, NK-cell Biofactory. This provides an allogeneic option to the previously published T-cell-based living vector that is limited by high manufacturing cost and product variability. The modularity of this pathway, which combines a "target" receptor with an "effector" function, enables reprogramming of the NK-cell Biofactory to target diseases with specific molecular biomarkers, such as cancer, viral infections, or auto-immune disorders, and overcome barriers that may affect the advancement of NK-cell therapies.
