Activation of brown fat thermogenesis increases energy expenditure and alleviates obesity. Sympathetic nervous system (SNS) is important in brown/beige adipocyte thermogenesis. Here we discover a fat-derived “adipokine” neurotrophic factor neurotrophin
Characterization of cellular growth is central to understanding living systems. Here, we applied a three-factor design to study the relationship between specific growth rate and genome-wide gene expression in 36 steady-state chemostat cultures of Sacchar
The global production of biodiesel in 2023 amounted to 34billion liters because compression ignition engines need environmentally friendly fuel alternatives. The research investigates Annona biodiesel in combination with machine learning (ML) and STATCOM (Static Synchronous Compensator) technology to enhance ...
R2R3-MYB transcription factors (TFs) are known to play a key role in regulating the expression of structural genes involved in plant flavonoid biosynthesis. However, the regulatory networks and related genes controlling isoflavonoid biosynthesis in soybe
FGF21 is a hormonal factor with important functions in the control of metabolism. FGF21 is found in rodent and human milk. Radiolabeled FGF21 administered to lactating dams accumulates in milk and is transferred to neonatal gut. The small intestine of neonatal (but not adult) mice highly expres...
From the previous section, we collected two sets of observations from two reference frames: L = c*T/2 (L.6) - Carriage length observed by Amy L' = (1-(v/c)**2)*c*T'/2 (L.21) - Carriage length observed by Bob Now if we agree with the time dilation formula discussed earlier...
Cloning and sequence analysis of NlFoxA Total RNA was isolated from four 2nd day brachypterous female adults of N. lugens using the Trizol kit (Invitrogen, USA). Its integrity was detected using Agilent 2100 (USA). First-strand cDNA was synthesized with a first strand synthesis kit using re...
