Nonlinear optics : asymmetry from symmetry
An unusual form of symmetry breaking in coupled microresonators with balanced optical gain and loss is now exploited to realize a novel type of optical isolator.
Modeling tools for dengue risk mapping : a systematic review
Introduction: The global spread and the increased frequency and magnitude of epidemic dengue in the last 50 years underscore the urgent need for effective tools for surveillance, prevention, and control. This review aims ...
Dose-response algorithms for water-borne Pseudomonas aeruginosa folliculitis
We developed two dose–response algorithms for P. aeruginosa pool folliculitis using bacterial and lesion density estimates, associated with undetectable, significant, and almost certain folliculitis. Literature data were ...
Selective lighting up of epiberberine alkaloid fluorescence by fluorophore-switching aptamer and stoichiometric targeting of human telomeric DNA G-quadruplex multimer
Aptamers, that exist naturally in living cells as functional elements and can switch nonfluorescent natural targets to fluorophores, are very useful in developing highly sensitive and selective biosensors and screening ...
Identification of a new export signal in Plasmodium yoelii : identification of a new exportome
Development of the erythrocytic malaria parasite requires targeting of parasite proteins into multiple compartments located within and beyond the parasite confine. Beyond the PEXEL/VTS pathway and its characterized players, ...
c-rel regulates Ezh2 expression in activated lymphocytes and malignant lymphoid cells
The polycomb group protein Ezh2 is a histone methyltransferase that modifies chromatin structure to alter gene expression during embryonic development, lymphocyte activation, and tumorigenesis. The mechanism by which Ezh2 ...
Melanoma-initiating cells exploit M2 macrophage TGFβ and arginase pathway for survival and proliferation
M2 macrophages promote tumor growth and metastasis, but their interactions with specific tumor cell populations are poorly characterized. Using a mouse model of spontaneous melanoma, we showed that CD34- but not CD34+ ...
Intracellular delivery of antisense peptide nucleic acid by fluorescent mesoporous silica nanoparticles
In order to overcome poor cell permeability of antisense peptide nucleic acid (PNA), a fluorescent mesoporous silica nanoparticle (MSNP) carrier was developed to successfully deliver antisense PNA into cancer cells for ...
A three dimensional vertically aligned multiwall carbon nanotube/NiCo2O4 core/shell structure for novel high-performance supercapacitors
Three dimensional (3D) vertically aligned structures have attracted tremendous attention from scientists in many fields due to their unique properties. In this work, we have built the 3D vertically aligned carbon nanotube ...
Binuclear oxidative addition of Sb-Cl bonds : a facile synthetic route to main group transition element clusters and rings
Binuclear oxidative addition of Sb–Cl bonds with the clusters Os3(CO)11(NCCH3), 1, or Os3(CO)10(NCCH3)2, 2, was found to be an effective synthetic route to organometallic clusters and rings containing μ2-SbPh2 or μ3-SbPh ...
