FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Maintenance of Stimuli Equivalence Classes: A Study with Students of Fundamental School
Psicologia, 2009 The maintenance of equivalence classes is affected by many experimental variables. The present study aimed to investigate the effect of classes size on the formation and maintenance of the equivalence relations with students of the fundamental school (9 ...

MATCHING‐TO‐SAMPLE ACCURACY ON FIXED‐RATIO SCHEDULES [PDF]
Journal of the Experimental Analysis of Behavior, 1979 Pigeons performing on a matching‐to‐sample procedure were exposed to six fixed‐ratio (FR) schedules (FR 1, 5, 10, 20, 40, and 60) of food reinforcement for correct matching responses. During both a correction and a noncorrection procedure without an intertrial interval (ITI), matching accuracy was lower on FR 1 and FR 60 than at intermediate ratios ...

REINFORCER EFFICACY IN A DELAYED MATCHING‐TO‐SAMPLE TASK [PDF]
Journal of the Experimental Analysis of Behavior, 1998 Five domestic hens were exposed to a delayed matching‐to‐sample task. Conditions 1, 5, and 8 were variable‐delay conditions in which five delays (0.25, 1, 2, 4, and 8 s) from the red or green sample to the presentation of the red and green comparison stimuli were presented a number of times during each session. In the fixed‐delay condition (Condition 3)

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

RECOMBINATIVE GENERALIZATION OF SUBWORD UNITS USING MATCHING TO SAMPLE [PDF]
Journal of Applied Behavior Analysis, 2010 The purpose of the current study was to develop and test a computerized matching‐to‐sample (MTS) protocol to facilitate recombinative generalization of subword units (onsets and rimes) and recognition of novel onset—rime and onset—rime—rime words. In addition, we sought to isolate the key training components necessary for recombinative generalization ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Same/different concept learning by capuchin monkeys in matching-to-sample tasks.
PLoS ONE, 2011 The ability to understand similarities and analogies is a fundamental aspect of human advanced cognition. Although subject of considerable research in comparative cognition, the extent to which nonhuman species are capable of analogical reasoning is ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
