Humans are equipped with some universal or language-specific abilities to recognize emotions. However, because of the different emotional contents in diverse languages and the relevant cultural differences, humans with different cultural backgrounds own different metapragmatical abilities to recognize and express emotions. A hypothesis concerning emotional effects about intonation and particle ...

Human languages are diverse and so precise statements of common properties must abstract away from specifics of particular languages. We note several abstract and absolute ‘Type 1’ universals and present some new ones built on a notion of ‘structural invariant’ that applies equally to constituent structure and individual grammatical morphemes. Crucially, these universals may be realized in stru...

Background: Progesterone is indispensable for differentiation of human endometrial stromal cells (HESCs) into decidual cells, a process that critically controls embryo implantation. However, HESCs also abundantly express androgen receptors (AR), yet the role of this member of the superfamily of ligand-dependent transcription factors in the decidual process remains poorly elucidated. Materials a...

In virtually all animals, males and females are morphologically, physiologically and behaviorally distinct. Using cDNA microarrays representing one-third of Drosophila genes to identify genes expressed sex-differentially in somatic tissues, we performed an expression analysis on adult males and females that: (1) were wild type; (2) lacked a germline; or (3) were mutant for sex-determination reg...

Antisense transcription, considered until recently as transcriptional noise, is a very common phenomenon in human and eukaryotic transcriptomes, operating in two ways based on whether the antisense RNA acts in cis or in trans. This process can generate long non-coding RNAs (lncRNAs), one of the most diverse classes of cellular transcripts, which have demonstrated multifunctional roles in fundam...
