Transfer integrals for oligos with different bases have been calculated using INDO/Koopman's approximation to unveil the charge transport mechanism in DNA. The sequences, G(A)nG, n = 1, 2, …, 10; G(A)xG(A)yG, x + y = 9; and G(A)xG(A)yG(A)zG, x + y + z = 8, were employed to interpret the Guanine (G) and Adenine(A) hopping. Adenine hopping is found to be faster in G(A)nG sequences with longer Adenin
Kaposi's sarcoma-associated herpes virus (KSHV) encodes a complement inhibitor named KSHV complement control protein (KCP). We have previously shown that KCP inhibits the human complement system by disrupting the C3 convertase of complement. KCP can accelerate the decay of the classical C3 convertase and it can act as a cofactor for factor I (R), which then cleaves and inactivates C4b or C3b (in t
Through new tracking techniques, data on timing and routes of migration in long-distance migrant birds are accumulating. However, studies of the consistency of migration of the same individuals between years are still rare in small-sized passerine birds. This type of information is important to understand decisions and migration abilities at the individual level, but also for life history theory,
Some complex plant-derived polysaccharides, such as modified citrus pectins and galactomannans, have been shown to have promising anti-inflammatory and anti-cancer effects. Most reports propose or claim that these effects are due to interaction of the polysaccharides with galectins because the polysaccharides contain galactose-containing side chains that might bind this class of lectin. However, t
High-precision analyses of the isotopic composition of methane in ambient air can potentially be used to discriminate between different source categories. Due to the complexity of isotope ratio measurements, such analyses have generally been performed in the laboratory on air samples collected in the field. This poses a limitation on the temporal resolution at which the isotopic composition can be
Background: The neotropical anopheline mosquito Anopheles darlingi is a major malaria vector in the Americas. Studies on mosquito-associated microbiota have shown that symbiotic bacteria play a major role in host biology. Mosquitoes acquire and transmit microorganisms over their life cycle. Specifically, the microbiota of immature forms is largely acquired from their aquatic environment. Therefore
Process-based land surface models are important tools for estimating global wetland methane (CH4) emissions and projecting their behavior across space and time. So far there are no performance assessments of model responses to drivers at multiple time scales. In this study, we apply wavelet analysis to identify the dominant time scales contributing to model uncertainty in the frequency domain. We
This work is concerned with the production of social space through cultural and performance practices; it proposes the collective production of space as a mode of resistance and examines performance manifestations, occupations and constructions within the contemporary neoliberal landscape. The thesis seeks to develop a mode of critical engagement with the spatial – its constraints and potentialiti
The identification of starting points for compound development is one of the key steps in early-stage drug discovery. Information-rich techniques such as crystallographic fragment screening can potentially increase the efficiency of this step by providing the structural information of the binding mode of the ligands in addition to the mere binding information. Here, we present the crystallographic
An effort to synthesize the Cu(I) variant of a lead-free double perovskite isostructural with Cs2AgInCl6 resulted in the formation of Cs3Cu4In2Cl13 nanocrystals with an unusual structure, as revealed by single-nanocrystal three-dimensional electron diffraction. These nanocrystals adopt a A2BX6 structure (K2PtCl6 type, termed vacancy ordered perovskite) with tetrahedrally coordinated Cu(I) ions. In
