Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

First-Principles Based Matrix-Green's Function Approach to Molecular Electronic Devices: General Formalism

open access: yes, 2001
Transport in molecular electronic devices is different from that in semiconductor mesoscopic devices in two important aspects: (1) the effect of the electronic structure and (2) the effect of the interface to the external contact. A rigorous treatment of

Biophysical analysis of angiotensin II and amyloid‐β cross‐interaction in aggregation and membrane disruption

open access: yesFEBS Letters, EarlyView.
Angiotensin II (AngII), a neuropeptide, interacts with amyloid‐β (Aβ), a key player in Alzheimer's disease. This study reveals that AngII reduces Aβ aggregation and membrane disruption in vitro. Biophysical assays and molecular modeling suggest AngII binds disordered Aβ forms, potentially modulating early amyloidogenic events and contributing to ...

A Molecular–Structure Hypothesis [PDF]

open access: yesInternational Journal of Molecular Sciences, 2010
The self-similar symmetry that occurs between atomic nuclei, biological growth structures, the solar system, globular clusters and spiral galaxies suggests that a similar pattern should characterize atomic and molecular structures. This possibility is explored in terms of the current molecular structure-hypothesis and its extension into four ...

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, EarlyView.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

Molecular mechanism of influenza A NS1-mediated TRIM25 recognition and inhibition

open access: yesNature Communications, 2018
NS1 of influenza A virus inhibits TRIM25 activity, which is an E3 ligase important for induction of the interferon response. Here, Koliopoulos et al. present structures of TRIM25 and NS1 and show how NS1 binding interferes with substrate recognition of ...

Preoperative assessment of cardiovascular risk in patients undergoing noncardiac surgery: the Orion study

open access: yesMonaldi Archives for Chest Disease, 2020
In patients undergoing noncardiac surgery risk indices can estimate patients’ perioperative risk of major cardiovascular complications. The indexes currently in use were derived from observational studies that are now outdated with respect to the current

High carrier mobility and strong fluorescence emission: Toward highly sensitive single‐crystal organic phototransistors

open access: yesAggregate, 2023
Organic single crystals (OSCs) offer a unique combination of both individual and collective properties of the employed molecules, but it remains highly challenging to achieve OSCs with both high mobilities and strong fluorescence emissions for their ...

Competitive Solvation of the Imidazolium Cation by Water and Methanol

open access: yes, 2014
Imidazolium-based ionic liquids are widely used in conjunction with molecular liquids for various applications. Solvation, miscibility and similar properties are of fundamental importance for successful implementation of theoretical schemes.

Structure determination from powder data : Mogul and CASTEP [PDF]

open access: yes, 2009
When solving the crystal structure of complex molecules from powder data, accurately locating the global minimum can be challenging, particularly where the number of internal degrees of freedom is large.
