RETREG1‐Mediated Reticulophagy is Essential for Dendritic Cell Maturation and Function in Sepsis

open access: yesAdvanced Science, EarlyView.
Reticulophagy regulator 1 (RETREG1) maintains dendritic cell (DC) maturation and function in early sepsis. Mechanistically, activating transcription factor 6 (ATF6) acts as a direct transcription factor regulating RETREG1 expression in response to sepsis‐induced endoplasmic reticulum (ER) stress.

ASSESSING THE LAND EQUIVALENT RATIO (LER) OF TWO CORN [ZEA MAYS L.] VARIETIES INTERCROPPING AT VARIOUS NITROGEN LEVELS IN KARAJ, IRAN [PDF]

open access: yesJournal of Central European Agriculture, 2006
The experiment was carried out to study effect of two corn varieties intercropping combinations (75%SC704:25%SC604, 50%SC704:50%SC604, 25%SC704:75%SC604) on land use efficiency at various nitrogen levels (150, 200, and 250 kg ha-1) using the Land ...

Targeting Endogenous Lipophagy: A Novel Strategy to Enhance MSC Osteogenesis and Mineralization for Senile Osteoporosis Therapy

open access: yesAdvanced Science, EarlyView.
Schematic representation of the role of lipophagy in bone mesenchymal stem cells(MSCs). In healthy MSCs, functional lipophagy efficiently degrades lipid droplets to support oxidative phosphorylation and cellular energy production, thereby facilitating osteogenic differentiation and matrix mineralization.

Life expectancy difference and life expectancy ratio: two measures of treatment effects in randomised trials with non-proportional hazards [PDF]

open access: yes, 2017
The hazard ratio (HR) is the most common measure of treatment effect in clinical trials that use time-to-event outcomes such as survival. When survival curves cross over or separate only after a considerable time, the proportional hazards assumption of ...

SERRATE Regulates Floral Meristem Activity by Antagonizing SHOOT MERISTEMLESS and Repressing Cytokinin Signaling

open access: yesAdvanced Science, EarlyView.
Floral meristem (FM) activity is crucial for the initiation of floral organs. In this study, SE represses IPT7 expression and cytokinin signaling via both the miR171c‐5p–KNAT2 and miR164c–CUC1/2–KNAT2 regulatory modules, thereby repressing FM activity. In contrast, STM induces both KNAT2 and IPT7 expression.

Atmospheric CO2 exchanges measured by eddy covariance over a temperate salt marsh and influence of environmental controlling factors [PDF]

open access: yesBiogeosciences
Within the coastal zone, salt marshes are atmospheric CO2 sinks and represent an essential component of biological carbon (C) stored on earth due to a strong primary production.

\u3cem\u3eFRIGIDA LIKE 2\u3c/em\u3e Is a Functional Allele in Landsberg \u3cem\u3eerecta\u3c/em\u3e and Compensates for a Nonsense Allele of \u3cem\u3eFRIGIDA LIKE 1\u3c/em\u3e [PDF]

open access: yes, 2006
The Landsberg erecta (Ler) accession of Arabidopsis (Arabidopsis thaliana) has a weak allele of the floral inhibitor FLOWERING LOCUS C (FLC). FLC-Ler is weakly up-regulated by the active San Feliu-2 (Sf2) allele of FRIGIDA (FRI-Sf2), resulting in a ...
