Structure of the hDmc1-ssDNA filament reveals the principles of its architecture [PDF]

open access: yes, 2010
In eukaryotes, meiotic recombination is a major source of genetic diversity, but its defects in humans lead to abnormalities such as Down's, Klinefelter's and other syndromes.

Toward Predicting Pandemic Potential: A Comparative Analysis of Virus‐Host Interactions Between Diverse Influenza A Viruses and the Human Innate Immune System

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Zoonotic infections caused by influenza A viruses (IAVs) of animal origin are a major public health concern, as they may represent the initial step toward the emergence of a pandemic strain. The host range of IAVs is shaped by species‐specific virus‐host interactions, and several host barriers have been identified that restrict the adaptation ...

Isolation of Lagos Bat Virus from Water Mongoose

open access: yesEmerging Infectious Diseases, 2006
A genotype 2 lyssavirus, Lagos bat virus (LBV), was isolated from a terrestrial wildlife species (water mongoose) in August 2004 in the Durban area of the KwaZulu-Natal Province of South Africa.

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Ginsenoside Rh1 Attenuates Alzheimer's Disease‐Like Deficits by Modulating Oxidative Stress and Mitochondrial Dysfunction via SIRT1‐Related Signaling

open access: yesPhytotherapy Research, EarlyView.
Rh1 attenuates oxidative stress and mitochondrial dysfunction through SIRT1‐related signaling. ABSTRACT Alzheimer's disease (AD) remains a progressive neurodegenerative disorder with limited therapeutic options. Ginsenoside Rh1 has been reported to possess neuroprotective properties, yet its specific role and underlying mechanisms in AD are not fully ...

Intracellular Crosslinking of Filoviral Nucleoproteins with Xintrabodies Restricts Viral Packaging

open access: yesFrontiers in Immunology, 2017
Viruses assemble large macromolecular repeat structures that become part of the infectious particles or virions. Ribonucleocapsids (RNCs) of negative strand RNA viruses are a prime example where repetition of nucleoprotein (NP) along the genome creates a

A nucleoprotein-hairpin in transcription regulation

open access: yes, 2009
Regulation of gene transcription in both prokaryotes and eukaryotes involves the formation of DNA–multiprotein complexes. These complexes build a precise three-dimensional topology allowing communication between distal regions of DNA.

Strategies for enhancing sensitivity in lateral flow assays

open access: yesVIEW, EarlyView.
Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural

D471G Mutation in LCMV-NP Affects Its Ability to Self-associate and Results in a Dominant Negative Effect in Viral RNA Synthesis

open access: yesViruses, 2012
Arenaviruses merit significant interest because several family members are etiological agents of severe hemorrhagic fevers, representing a major burden to public health.

Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

open access: yesIntegrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...
