Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

A computational theory for the learning of equivalence relations
Frontiers in Human Neuroscience, 2011 Equivalence relations are logical entities that emerge concurrently with the development of language capabilities.In this work we propose a computational model that learns to build equivalence relations by learning simple conditional rules.

NAMING IN CONDITIONAL DISCRIMINATION AND STIMULUS EQUIVALENCE [PDF]
Journal of the Experimental Analysis of Behavior, 1989 Using a matching‐to‐sample procedure, McIntire, Cleary, and Thompson (1987) taught monkeys the conditional relations A1‐R1‐A1‐R1, A2‐R2‐A2‐R2, A1‐R1‐B1‐R1, A2‐R2‐B2‐R2, B1‐R1‐C1‐R1, and B2‐R2‐C2‐R2, where the first and third terms in each relation refer to the sample and comparison stimuli, respectively, and the second and last terms refer to the ...

Stimulus novelty effects during stimulus equivalence testing [PDF]
Psychonomic Science, 1971 An analysis is performed on the transfer test data from an experiment which factorially combines percent reward (50% vs 100%) and duration of confinement (2 vs 20 sec) in the presence of cue values from two redundant stimulus dimensions. Rats perform better on test trials which pair the previously negative cues with novel compound cues than on trials ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Stimulus Equivalence and Increase of Correct Responses in Addition and Subtraction Problems
Paidéia (Ribeirão Preto), 2013 In order to propose interventions that increase correct responses, investigations search for properties of arithmetic problems that hinder its solution. This study assessed whether the formation of two sets of addition and subtraction equivalence classes

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
