Economic Impact Assessment of Brackish Groundwater in Kirana Hills Region, District Chiniot, Pakistan

open access: yesInternational Journal of Economic and Environment Geology, 2018
Good quality water is the basic need of every citizen. Contaminated water not only affects our health but also damages household items such as sanitary materials. The purpose of this study is to assess the economic impact of high Total

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Characterisation of classical enterotoxins, virulence activity, and antibiotic susceptibility of Staphylococcus aureus isolated from Thai fermented pork sausages, clinical samples, and healthy carriers in northeastern Thailand

open access: yesJournal of Veterinary Research, 2020
Contamination by Staphylococcus aureus of food produced from animal sources may have diverse and multifactorial causes that depend on geographical distribution. The goal of this study was to isolate and characterise S.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Room temperature silanization of Fe3O4 for the preparation of phenyl functionalized magnetic adsorbent for dispersive solid phase extraction for the extraction of phthalates in water

open access: yesGreen Processing and Synthesis, 2019
The preparation of magnetic solid adsorbents for solid phase extraction often involved time-consuming stepwise reaction and high-temperature reaction. In this study, the coating of silica and the functionalization of magnetite were performed in a single ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Polydopamine-Coated Magnetite as a Sensing Material for the Optical Detection of Cationic Surfactants

open access: yesChemosensors
The sensing of surfactants is a topic of interest for industrial and environmental purposes. Polydopamine-coated magnetite (Fe3O4@PDA) can be a relevant support for the detection of cationic surfactants in water samples.

Direct As(V) Determination Using Screen-Printed Electrodes Modified with Silver Nanoparticles

open access: yesNanomaterials, 2020
Carbon-nanofiber-based screen-printed electrodes modified with silver nanoparticles (Ag-NP-SPCNFEs) were tested in a pioneering manner for the direct determination of As(V) at low μg L−1 levels by means of differential pulse anodic stripping voltammetry.

Determination of iron in natural and mineral waters by flame atomic absorption spectrometry [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
Simple methods for the determination of Fe in natural and mineral waters by flame atomic absorption spectrometry (AAS) are suggested. The results of the investigation of selectivity of the proposed AAS method proved that this procedure is not affected by

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
