Minimizing the Reorganization Energy of Cobalt Redox Mediators Maximizes Charge Transfer Rates from Quantum Dots.

Light-induced charge separation is at the very heart of many solar harvesting technologies. The reduction of energetic barriers to charge separation and transfer increases the rate of separation and the overall efficiency of these technologies. Here we report that the internal reorganization energy of the redox acceptor, the movement of the atoms with changing charge, has a profound effect on the charge transfer rates from donor quantum dots.

Filovirus VP24 Proteins Differentially Regulate RIG-I and MDA5-Dependent Type I and III Interferon Promoter Activation.

Filovirus family consists of highly pathogenic viruses that have caused fatal outbreaks especially in many African countries. Previously, research focus has been on Ebola, Sudan and Marburg viruses leaving other filoviruses less well studied. Filoviruses, in general, pose a significant global threat since they are highly virulent and potentially transmissible between humans causing sporadic infections and local or widespread epidemics.

Genetic variations of toll-like receptors: Impact on susceptibility, severity and prognosis of bacterial meningitis.

Bacterial meningitis (BM) is a serious infectious disease of the central nervous system，which is mainly caused by Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae, Group B Streptococcus and Listeria monocytogenes. Throughout the world, BM has become one of the most lethal diseases that commonly occurs in children. Toll like receptors (TLRs) are one of the most important immune defense lines in infectious diseases, and play an essential role in host defense.

Effectiveness of the Close Collaboration with Parents intervention on parent-infant closeness in NICU.

Background: Parent-infant closeness during hospital care of newborns has many benefits for both infants and parents. We developed an educational intervention for neonatal staff, Close Collaboration with Parents, to increase parent-infant closeness during hospital care. The aim of this study was to evaluate the effectiveness of the intervention on parent-infant closeness in nine hospitals in Finland.

Ebolavirus protein VP24 interferes with innate immune responses by inhibiting interferon-λ1 gene expression.

Ebolaviruses (EBOV) cause severe disease with a recent outbreak in West Africa in 2014-2015 leading to more than 28 000 cases and 11 300 fatalities. This emphasizes the urgent need for better knowledge on these highly pathogenic RNA viruses. Host innate immune responses play a key role in restricting the spread of a viral disease.

Cobalt cage complexes as mediators of protein electron transfer.

A selection of cobalt (III)/(II) macrobicyclic 'sarcophagine' (sar) cage complexes with NS mixed donor sets but differing in a single apical substituent has been chosen to span a redox potential range of +150 to -150 mV vs the normal hydrogen electrode and thus acts as redox buffers in protein spectroelectrochemistry and redox potentiometry. The cobalt(III) cage complexes are all based on the same parent structure [Co(XMeNSsar)], where X, the variable apical substituent, is -NO, -Cl, -OH, -NH or -NMe , and a methyl group occupies the opposite apical position. The X-ray crystal structures of selected members of this series are reported.

Production, purification and immunogenicity of recombinant Ebola virus proteins - A comparison of Freund's adjuvant and adjuvant system 03.

There is an urgent need for Ebola virus (EBOV) proteins, EBOV-specific antibodies and recombinant antigens to be used in diagnostics and as potential vaccine candidates. Our objective was to produce and purify recombinant proteins for immunological assays and for the production of polyclonal EBOV specific antibodies. In addition, a limited comparison of the adjuvant effects of Freund's complete adjuvant (FCA) and adjuvant system 03 (AS03) was carried out.
