Analysis of Solubility, pH, Antimicrobial Action and Cytotoxicity of Calcium Hydroxide Paste Associated With Ambroxol Hydrochloride

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the association of ambroxol hydrochloride with calcium hydroxide paste as intracanal medication to enhance antimicrobial action on biofilm without affecting pH, solubility and cytotoxicity. Calcium hydroxide (CH) paste and formulations with different ambroxol concentrations were placed into artificial teeth conditioned in ...

The value of saltbush revegetation for biodiversity in a highly fragmented landscape

Conservation Science and Practice, EarlyView.
Saltbush revegetation provides limited value for faunal biodiversity. Saltbush has the lowest species richness and diversity of ants, spiders, and birds. Remnant habitats continue to provide the most important habitats for native species. Abstract Secondary salinization is a significant global issue affecting up to 1 billion hectares of land, impacting

Cyanobacteria and cyanotoxins: the influence of nitrogen versus phosphorus.

PLoS ONE, 2012
The importance of nitrogen (N) versus phosphorus (P) in explaining total cyanobacterial biovolume, the biovolume of specific cyanobacterial taxa, and the incidence of cyanotoxins was determined for 102 north German lakes, using methods to separate the ...

Rivers affect the biovolume and functional traits of phytoplankton in floodplain lakes

Acta Limnologica Brasiliensia, 2017
Aim: We analyzed the temporal distribution (dry and rainy periods) of phytoplankton functional groups (biovolume) from lakes connected to dammed (S1 - Paraná River) and non-dammed rivers (S2 - Baia River and S3 - Ivinhema River) in the upper Paraná River

Influence of nanohydroxyapatite mouthwash on the growth of Candida albicans biofilm on milled denture surfaces: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose There is a need for effective solutions for the persistent prevalence of denture stomatitis (DS) in denture‐wearing populations. This study assessed the impact of nanohydroxyapatite (nanoHAP) nanoparticles on Candida albicans biofilm formation on milled polymethylmethacrylate (PMMA) denture bases.
