Representation Levels Within Knowledge Representation [PDF]
, 2007 Representation of knowledge is used to store and retrieve informational data in a machine. Since meaningcannot be directly stored in the computer; this work proposes a series of levels of representation. The meaning of the data is transformed to a format that the machine can use to store and retrieve knowledge.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

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.

ViaticaThis article examines Isabelle Eberhardt’s last work, the travelogue Sud Oranais, in order to shed some light on her views and representations of the “women of the desert”. Her perspective proves to be quite complex and ambiguous, mixing the depreciatory

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 ...

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.

Alegorías, metáforas y símbolos en el cine sobre la Revolución mexicana
Caravelle, 2011 This work intends to analyze the way Mexican cinema has built allegoric images of the Mexican Revolution through sequences or key scenes which, far from being a collection of official images, show the complexity of the Mexican filmmakers’ vision of the ...

On Medial Representations [PDF]
, 2008 During the last half century, medial representations of objects have been involved in many biological and physical theories, and computer scientists have designed suitable algorithms for their computation. Aim of this paper is to provide a short, non-comprehensive, survey of the most common medial representation systems.

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 ...
