Feb 13, 2020
The type II restriction endonuclease TseI recognizes the DNA target sequence 5'-G^CWGC-3' (where W = A or T) and cleaves after the first G to produce fragments with three-base 5'-overhangs. We have determined that it is a...

B-hadron production in NNLO QCD
We calculate, for the first time, the NNLO QCD corrections to identified
heavy hadron production at hadron colliders. The calculation is based on a
flexible numeric framework which allows the calculation of any distribution of

Reduction of the geomagnetic field delays Arabidopsis thaliana flowering time through downregulation of flowering-related genes.
Chiara Agliassa, Ravishankar Narayana, Cinzia M Bertea, Christopher T Rodgers, Massimo E Maffei
Jun 21, 2018
Variations in magnetic field (MF) intensity are known to induce plant morphological and gene expression changes. In Arabidopsis thaliana Col-0, near-null magnetic field (NNMF, i.e., <100 nT MF) causes a delay in the transition...

Glycogen synthase kinase 3 (GSK-3) controls T-cell motility and interactions with antigen presenting cells.
OBJECTIVE:The threonine/serine kinase glycogen synthase kinase 3 (GSK-3) targets multiple substrates in T-cells, regulating the expression of Tbet and PD-1 on T-cells. However, it has been unclear whether GSK-3 can affect the...

Relationships between resting conductances, excitability, and t-system ionic homeostasis in skeletal muscle.
Activation of skeletal muscle fibers requires rapid sarcolemmal action potential (AP) conduction to ensure uniform excitation along the fiber length, as well as successful tubular excitation to initiate excitation-contraction...
