DNA Variation and Language Affinities [PDF]
The American Journal of Human Genetics, 1997 Populations tend to diverge genetically because of genetic drift, but their differences are reduced by the exchange of individuals or gametes—in brief, by gene flow. The evolutionary weight of drift depends on a property of each single population—its effective size.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

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 ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Borealis: An International Journal of Hispanic Linguistics, 2016 Desde que Hugo Schuchardt defendiera que toda lengua es un continuum en variación (Abad 1993: 76), como objeto de estudio la variación lingüística ha sido abordada desde múltiples enfoques científicos que se han centrado en la variación tanto como la ...

Diachronic and/or synchronic variation? The acquisition of sociolinguistic competence in L2 French. [PDF]
, 2007 A majority of the early research in Second Language Acquisition focused on diachronic variation in the learners’ interlanguage (IL), that is, differences in the IL linked to a supposed increase in knowledge between two points in time (cf.

FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

DEDICATED TO LANGUAGE VARIATIONS
The International Journal of Applied Language Studies and Culture, 2020 We use languages for different purposes in everyday life. Most people use more than one language, and they may be considered as bilingual (speaking two languages) or multilingual (speaking more than two languages). In simple terms, as Wardhaugh elaborates, language may be defined as a code or system that is used by societies to communicate with other ...

Examining variation in the expression of tense/aspect to classify the Kikongo Language Cluster [PDF]
, 2015 In this article we examine variation in the expression of tense and aspect (TA) in 23 modern and two historical Bantu language varieties belonging to Guthrie’s B40, H10 and H30 groups in order to shed light on the internal classification of the Kikongo ...
