Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

open access: yesThe FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

Performance of full-rate and partial-diversity multiple antennas space-time block code with low complexity

open access: yesTongxin xuebao, 2005
On the basis of existing full-diversity space-time block coding (STBC), two full-rate complex orthogonal STBC schemes for multiple antennas were proposed.

Turbo coding

open access: yes
Περίληψη: Οι κώδικες Turbo ανήκουν στην κλάση των υψηλής απόδοσης κωδίκων διόρθωσης λαθών και είναι οι πρώτοι πρακτικοί κώδικες οι οποίοι πετυχαίνουν σε απόδοση το όριο του Shannon. Οι κώδικες Turbo χρησιμοποιούνται στα κινητά δίκτυα 3G και 4G, στο πρώτυπο WiMAX, και στις δορυφορικές επικοινωνίες καθώς και σε διάφορες εφαρμογές όπου οι σχεδιαστές ...

Quantitative analysis of DNA‐GATA1 binding alterations linked to hematopoietic disorders

open access: yesThe FEBS Journal, EarlyView.
Native holdup allows the quantitative determination of affinities between full‐length transcription factors and DNA. Mutations in either the protein or the DNA can modulate binding strength, which can be precisely quantified using this approach. Applied to GATA1, it revealed mutations that alter DNA binding.

FcMAPK4‐phosphorylated FcNOR activates FcERF5 to promote fig fruit softening through activation of FcPG12 expression

open access: yesJournal of Integrative Plant Biology, EarlyView.
In Ficus carica fruit, the MAP kinase FcMAPK4 phosphorylates the NAC transcription factor FcNOR, which cooperates with ethylene response factor FcERF5 to activate the pectin degradation gene FcPG12, thereby promoting rapid softening of fig fruit. ABSTRACT Rapid softening of fig (Ficus carica L.) fruit during ripening leads to extremely short shelf life;

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...
