We model the polarization-dependent photocontractions of polydomain nematic elastomers. Contraction initially arises by light-induced director rotation. At higher light intensity, strain recovers because the local order parameter diminishes. Thus we predict photostrains to be nonmonotonic with light intensity and predict the induction of a negative global order parameter for the system of polyd...

Cellular metabolism is increasingly recognized as a controller of immune cell fate and function. MicroRNA-33 (miR-33) regulates cellular lipid metabolism and represses genes involved in cholesterol efflux, HDL biogenesis, and fatty acid oxidation. Here, we determined that miR-33-mediated disruption of the balance of aerobic glycolysis and mitochondrial oxidative phosphorylation instructs macrop...

Integrin receptors play a central role in the biology of lymphocytes, mediating crucial functional aspects of these cells, including adhesion, activation, polarization, migration, and signaling. Here we report that induction of activation of the beta2-integrin lymphocyte function-associated antigen 1 (LFA-1) in T lymphocytes with divalent cations, phorbol esters, or stimulatory antibodies is fo...

We examined the effects of incidental anger on perceived and actual polarization between Democrats and Republicans in the context of two national tragedies, Hurricane Katrina (Study 1) and the mass shooting that targeted Representative Gabrielle Giffords in Arizona (Study 2). We hypothesized that because of its relevance to intergroup conflict, incidental anger exacerbates the political polariz...

CD5L (CD5 molecule-like) is a secreted glycoprotein that controls key mechanisms in inflammatory responses, with involvement in processes such as infection, atherosclerosis, and cancer. In macrophages, CD5L promotes an anti-inflammatory cytokine profile in response to TLR activation. In the present study, we questioned whether CD5L is able to influence human macrophage plasticity, and drive its...

We propose a new formulation for the Æther of Dirac based on a lagrangian approach. We analyse how the presence of a particular self-interaction term in the lagrangian lead us to a description of the æther as being a medium with conductivity which is governed by macroscopic Maxwell equations with a polarization tensor Mαβ depending on the vector potential. These results are then applied to the ...

OBJECTIVE We have previously shown an increased expression of complement 3 (C3) in the perivascular adipose tissue (PVAT) in the deoxycorticosterone acetate (DOCA)-salt hypertensive model. This study aims to examine the role and underlying mechanism of C3 in PVAT for understanding the pathogenesis of hypertensive vascular remodeling further. APPROACH AND RESULTS The role of C3 in macrophage p...

background: Classical macrophages (M1) and alternative macrophages (M2) are responsible for various functions in order to maintain homeostasis. BCG vaccine and hydatid cyst fluid can be examples of stimulants which can cause M1and M2 macrophage polarization. Evaluating the expression of markers such as IFNγ and TNFα for M1 phenotype and TGFβ and IL4 for M2 phenotype is one of the confirmatory w...

Beam polarization measurement in scattering experiments with a high accuracy and the lowest possible cost is an important issue. In this regard, deuteron beam polarization was measured in the low-energy beam line easily with a relatively low cost procedure and in a very short time by Lamb Shift Polarimeter (LSP). Also, the beam polarization has been measured in high-energy beam line with BINA. ...

The polar distribution of the ActA protein on the surface of the Gram-positive intracellular bacterial pathogen, Listeria monocytogenes, is required for bacterial actin-based motility and successful infection. ActA spans both the bacterial membrane and the peptidoglycan cell wall. We have directly examined the de novo ActA polarization process in vitro by using an ActA-RFP (red fluorescent prot...
