(
Asian Network for Scientific Information
, 2017 , Article)
Background and Objective: Synergistic combinations of various antimicrobial agents have been introduced as extra successful strategies to combat multidrug resistant (MDR) infections. This study was undertaken to evaluate ...
The replacement of five consecutive amino acids in the cyt1a protein of bacillus thuringiensis enhances its cytotoxic activity against lung epithelial cancer cells
(
MDPI AG
, 2018 , Article)
Cyt1A protein is a cytolytic protein encoded by the cyt gene of Bacillus thuringiensis subsp. israelensis (Bti) as part of the parasporal crystal proteins produced during the sporulation. Cyt1A protein is unique compared ...
Impaired Liver Size and Compromised Neurobehavioral Activity are Elicited by Chitosan Nanoparticles in the Zebrafish Embryo Model
(
MDPI
, 2019 , Article)
The use of chitosan nanoparticles (ChNPs) in various biological and environmental
applications is attracting great interest. However, potential side effects related to ChNP toxicity
remain the major limitation hampering ...
Evaluating the effect of antiscalants on membrane biofouling using FTIR and multivariate analysis
(
Taylor and Francis Ltd.

This work aims to undertake a preliminary characterization of winter fish assemblages in the salt marsh areas of Guadiana lower estuary (South-East Portugal) and discusses the potential risks of habitat dominance by a ...
Mitogenomics of the extinct cave lion, Panthera spelaea (Goldfuss, 1810), resolve its position within the panthera cats
(
Ubiquity Press
, 2016 , Article)
The extinct cave lion (Panthera spelaea) was an apex predator of the Pleistocene, and one of the largest felid species ever to exist. We report the first mitochondrial genome sequences for this species, derived from two ...
Optimization of bioinsecticides overproduction by Bacillus thuringiensis subsp. kurstaki using linear regression
(
Polish Society of Microbiologists
, 2013 , Article)
A multiple linear regression analyses were performed to screen for the significant factors simultaneously influencing production of delta-endotoxin, proteolytic activities and spore formation by a Bacillus thuringiensis ...
Early stage litter decomposition across biomes
(
Elsevier
, 2018 , Article)
Through litter decomposition enormous amounts of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to understand the ...
Born small, die young: Intrinsic, size-selective mortality in marine larval fish
(
Nature Publishing Group
, 2015 , Article)
Mortality during the early stages is a major cause of the natural variations in the size and recruitment strength of marine fish populations. In this study, the relation between the size-at-hatch and early survival was ...
