Dental enamel, a hierarchical material composed primarily of hydroxylapatite nanowires, is susceptible to degradation by plaque biofilm-derived acids. The solubility of enamel strongly depends on the presence of Mg(2+), F(-), and CO3(2-). However, determining the distribution of these minor ions is challenging. We show—using atom probe tomography, x-ray absorption spectroscopy, and correlative ...

AbstractThe multimammate mouse (Mastomys natalensis) is the reservoir for Lassa virus (LASV). Zoonotic transmission occurs when humans are directly or indirectly exposed to fluids of the multimammate mouse, such as urine, saliva, and blood. Housing characteristics and domestic organization affect rodent density in and around households and villages, and are likely to be a risk factor for Lassa ...

We tested the efficacy and palatability of nine commercial rodenticide bait formulations on Polynesian rats (Rattus exulans), roof rats (R. rattus), and house mice (Mus musculus). Efficacy varied by rodenticide tested and rodent species. Generally, rodenticides were more effective against mice than for either of the rat species, and mice tended to consume more rodenticide bait than the laborato...

PURPOSE This review aims to provide a literature survey of the association between photo-oxidation of lens proteins and lipid peroxidation with the genesis of age-related cataract in laboratory studies using rodent models, in epidemiological and interventional studies in humans. MATERIALS AND METHODS A Medline search using initial search terms lens, oxidation, antioxidant, and diet was employ...

BACKGROUND AND OBJECTIVE Light scattering from collagen within skin limits light-based therapeutics while increasing the risk of epidermal thermal injury. Specific chemicals show the ability to reduce light scattering by reversibly altering the optical properties of skin. This study examines the correlation between collagen solubility and the optical clearing potential (OCP) of sugars and sugar...

The mammalian and flea fauna of La Rioja Province is one of the least known from northwestern Argentina. In this study, the distribution and nomenclature of 13 species of fleas of bats and rodents from La Rioja Province are updated. Four species of fleas are recorded for the first time in La Rioja Province including a new record for northwestern Argentina, and two new flea-host associations. An...

Grasses are recognized as a critical regeneration barrier in tropical pastures, yet the effects of rodents and rodent–grass interactions not well understood. As selective foragers, could shape tree communities, moderating biodiversity regenerating landscapes. We utilized fully crossed two-way factorial design to examine effect that grasses, rodents, their interaction had on seedling establishme...

linguatula serrata is one of the important zoonotic parasites. carnivores serve as definitive host. the larvae existed in mesenteric lymph nodes (mlns), liver, lungs, etc of intermediate herbivores. the definitive host becomes infected by ingesting viscera containing the infective nymphal stage. humans may be infected with linguatula either by ingestion of nymphs resulting in a condition called...

rodent ectoparasites seems have a main role in transmission of some zoonotic pathogens from commensal rats to human and pets such as leishmaniasis, plague, cchf, etc. so rodents as the main reservoirs, are potential health dangers in human communities. the aim of this study was to determine the prevalence and frequency of identified ectoparasites in north of tehran . rodents were captured with ...
