Synthesis of DNA-Templated Silver Nanoclusters and the Characterization of Their Optical Properties and Biological Activity.

DNA-templated silver nanoclusters (DNA-AgNCs) are a unique class of bioinorganic nanomaterials. The optical properties and biological activities of DNA-AgNCs are readily modulated by the minor adjustments in the sequence or structure of the templating oligonucleotide. Excitation-emission matrix spectroscopy (EEMS) enables the fluorescence of compounds to be measured in a way that examines the entirety of a material's fluorescent properties.

Small Volume Microrheology to Evaluate Viscoelastic Properties of Nucleic Acid-Based Supra-Assemblies.

Particle tracking (PT) microrheology is a passive microrheological approach that characterizes material properties of soft matter. Multicomponent materials with the ability to create extensive crosslinking, such as supra-assemblies, may exhibit a complex interplay of viscous and elastic properties with a substantial contribution of liquid phase still diffusing through the system. Microrheology analyzes the motion of microscopic beads immersed in a sample, making it possible to evaluate the rheological properties of biological supra-assemblies.

Optical, structural, and biological properties of silver nanoclusters formed within the loop of a C-12 hairpin sequence.

Silver nanoclusters (AgNCs) are the next-generation nanomaterials representing supra-atomic structures where silver atoms are organized in a particular geometry. DNA can effectively template and stabilize these novel fluorescent AgNCs. Only a few atoms in size - the properties of nanoclusters can be tuned using only single nucleobase replacement of C-rich templating DNA sequences.

Optical, structural and antibacterial properties of silver nanoparticles and DNA-templated silver nanoclusters.

Silver nanoparticles (AgNPs) are increasingly considered for biomedical applications as drug-delivery carriers, imaging probes and antibacterial agents. Silver nanoclusters (AgNCs) represent another subclass of nanoscale silver. AgNCs are a promising tool for nanomedicine due to their small size, structural homogeneity, antibacterial activity and fluorescence, which arises from their molecule-like electron configurations.

Therapeutic immunomodulation by rationally designed nucleic acids and nucleic acid nanoparticles.

The immune system has evolved to defend organisms against exogenous threats such as viruses, bacteria, fungi, and parasites by distinguishing between "self" and "non-self". In addition, it guards us against other diseases, such as cancer, by detecting and responding to transformed and senescent cells. However, for survival and propagation, the altered cells and invading pathogens often employ a wide range of mechanisms to avoid, inhibit, or manipulate the immunorecognition.

Non-Lethal Detection of -Like (RUK13) and -Like (PDE18) Ranaviruses in Two UK-Native Amphibian Species.

Ranaviruses have been involved in amphibian mass mortality events worldwide. Effective screening to control this pathogen is essential; however, current sampling methods are unsuitable for the detection of subclinical infections. Non-lethal screening is needed to prevent both further spread of ranavirus and losses of at-risk species.

Heritage-specific oral microbiota in Indigenous Australian dental calculus.

Background And Objectives: Aboriginal Australians and Torres Strait Islanders (hereafter respectfully referred to as Indigenous Australians) experience a high burden of chronic non-communicable diseases (NCDs). Increased NCD risk is linked to oral diseases mediated by the oral microbiota, a microbial community influenced by both vertical transmission and lifestyle factors. As an initial step towards understanding the oral microbiota as a factor in Indigenous health, we present the first investigation of oral microbiota in Indigenous Australian adults.

Biocultural Drivers of Salivary Microbiota in Australian Aboriginal and Torres Strait Islander Children.

Australian Aboriginal and Torres Strait Islander children experience unacceptably high rates of dental caries compared to their non-Indigenous Australian counterparts. Dental caries significantly impacts the quality of life of children and their families, particularly in remote communities. While many socioeconomic and lifestyle factors impact caries risk, the central role of the oral microbiota in mediating dental caries has not been extensively investigated in these communities.

Effectiveness of decontamination protocols when analyzing ancient DNA preserved in dental calculus.

Ancient DNA analysis of human oral microbial communities within calcified dental plaque (calculus) has revealed key insights into human health, paleodemography, and cultural behaviors. However, contamination imposes a major concern for paleomicrobiological samples due to their low endogenous DNA content and exposure to environmental sources, calling into question some published results. Decontamination protocols (e.

Post-epizootic microbiome associations across communities of neotropical amphibians.

Microbiome-pathogen interactions are increasingly recognized as an important element of host immunity. While these host-level interactions will have consequences for community disease dynamics, the factors which influence host microbiomes at larger scales are poorly understood. We here describe landscape-scale pathogen-microbiome associations within the context of post-epizootic amphibian chytridiomycosis, a disease caused by the panzootic chytrid fungus Batrachochytrium dendrobatidis.

Cross-Disciplinary Genomics Approaches to Studying Emerging Fungal Infections.

Emerging fungal pathogens pose a serious, global and growing threat to food supply systems, wild ecosystems, and human health. However, historic chronic underinvestment in their research has resulted in a limited understanding of their epidemiology relative to bacterial and viral pathogens. Therefore, the untargeted nature of genomics and, more widely, -omics approaches is particularly attractive in addressing the threats posed by and illuminating the biology of these pathogens.

Response of Salivary Microbiota to Caries Preventive Treatment in Aboriginal and Torres Strait Islander Children.

A once-annual caries preventive (Intervention) treatment was offered to Aboriginal and Torres Strait Islander schoolchildren-a population with disproportionately poorer oral health than non-Indigenous Australian children-in the Northern Peninsula Area (NPA) of Far North Queensland (FNQ), which significantly improved their oral health. Here, we examine the salivary microbiota of these children (mean age = 10 ± 2.96 years; n = 103), reconstructing the bacterial community composition with high-throughput sequencing of the V4 region of bacterial gene.

Consequences of colonialism: A microbial perspective to contemporary Indigenous health.

Nearly all Indigenous populations today suffer from worse health than their non-Indigenous counterparts, and despite interventions against known factors, this health "gap" has not improved. The human microbiome-the beneficial, diverse microbial communities that live on and within the human body-is a crucial component in developing and maintaining normal physiological health. Disrupting this ecosystem has repercussions for microbial functionality, and thus, human health.

Prevalence of enterococcus species and their virulence genes in fresh water prior to and after storm events.

Enterococcus spp. isolates (n = 286) collected from six surface water bodies in subtropical Brisbane, Australia, prior to and after storm events, were identified to species level and tested for the presence of seven clinically important virulence genes (VGs). Enterococcus faecalis (48%), Enterococcus faecium (14%), Enterococcus mundtii (13%), and Enterococcus casseliflavus (13%) were frequently detected at all sites.

Catamenial pneumothorax.

Pneumothorax is a potentially life-threatening condition caused by an accumulation of air or gas in the pleural space. This may occur either spontaneously or as a result of disease or injury. The term "catamenial" is derived from the Greek meaning "monthly".

Tackling toddler obesity through a pilot community-based family intervention.

The lack of effective child obesity intervention and intervention prevention programmes is an increasing concern for public health professionals. Since eating and physical activity habits become established in the early years, these efforts should start as early as possible. A pilot programme, Fighting Fit Tots, was developed within a local Sure Start area.
