A deficiency of mixed function oxidase activities in the cholesterol biosynthetic pathway of human granulocytes.

open access: yesJournal of Lipid Research, 1980
Highly purified human granulocytes synthesize [14C]farnesol and [14C]squalene but not [14C]sterols from [14C]mevalonic acid. Dimethylsulfoxide was found to be an excellent vehicle for carrying [3H]squalene-2, 3-oxide into the intact cells.

Stimulus-responsive Injectable Polysaccharide Scaffolds for Soft Tissue Engineering Prepared by O/W High Internal Phase Emulsion [PDF]

open access: yes, 2011
This thesis describes work on the development of several novel stimuli-responsive porous hydrogels prepared from oil-in-water (o/w) high internal phase emulsion (HIPE) as injectable scaffolds for soft tissue engineering.

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

open access: yesPest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Mechanism of lubrication by tricresylphosphate (TCP) [PDF]

open access: yes
The coefficient of friction was measured as a function of temperature on a pin-on-disk tribometer. Pins and disks of 440C and 52100 steels were lubricated with tricresylphosphate (TCP), 3.45 percent TCP in squalene, and pure squalene.

The Chemistry From Tin Iodide Molecular Inks to FASnI3 Nanocrystals

open access: yesSmall, EarlyView.
The complexation dynamics of SnI2 with two benchmark Lewis bases (oleylamine and trioctylphosphine) at different ligand loadings, as well as an amine‐free zwitterionic approach, were directly correlated with the formation of different perovskite nanostructures, establishing a predictive framework for designing robust molecular inks for tin halide ...

Contrasted Reactivity to Oxygen Tensions in Frankia sp. Strain CcI3 throughout Nitrogen Fixation and Assimilation [PDF]

open access: yes, 2014
Reconciling the irreconcilable is a primary struggle in aerobic nitrogen-fixing bacteria. Although nitrogenase is oxygen and reactive oxygen species-labile, oxygen tension is required to sustain respiration.

A feasibility study on the application of MICRO XRF for latent fingermark detection on porous surfaces

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract In the context of criminal investigations, latent fingermarks play a pivotal role in obtaining clues related to suspects. Presently, various physical, chemical, and optical methods are employed for latent fingermark detection. However, it is observed that when utilizing physical and chemical techniques, latent fingermarks may sometimes suffer ...

Regulation of squalene epoxidase in HepG2 cells.

open access: yesJournal of Lipid Research, 1990
Regulation of squalene epoxidase in the cholesterol biosynthetic pathway was studied in a human hepatoma cell line, HepG2 cells. Since the squalene epoxidase activity in cell homogenates was found to be stimulated by the addition of Triton X-100, enzyme ...

Surface mineral crusts: A priority target in search for life on Mars [PDF]

open access: yes, 2006
Mineral crusts are strong candidates in the search for evidence of life during planetary exploration, and should be an important target for examination in impact craters.

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.
