Differentiation of Plant and Animal‐Derived Cholesterol Using irm‐13C NMR and IRMS

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Determining and certifying the origin of ingredients, starting materials, and excipients used in manufactured goods like cosmetics and medicines can be difficult. In this report, we describe a robust approach for identifying the origin of cholesterol, a component of myriad consumer products using irm‐13C NMR and IRMS to differentiate plant versus ...

How does Cross-Linking Effect the Thermal Stability of Polyisoprene [PDF]

open access: yes, 2000
Polyisoprene can be cross-linked by an initial lithiation followed by reaction with both monochloro compounds and dichloro compounds. The monochloro compounds effect crosslinking through a lithium-chlorine exchange route while the use of dichloro ...

Pb2+ tolerance by Frankia sp. strain EAN1pec involves surface-binding [PDF]

open access: yes, 2017
Several Frankia strains have been shown to be lead-resistant. The mechanism of lead resistance was investigated for Frankia sp. strain EAN1pec. Analysis of the cultures by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX ...

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.

Expression of WsSQS and WsSQS2 in Tobacco Divergently Regulates Terpenoid Metabolism and Enhances Squalene Accumulation

open access: yesAgronomy
Biosynthesis of squalene in the plant chassis has broad application prospects, and identifying efficient enzymes is of great importance. Here, we analyzed the function of squalene synthase genes WsSQS and WsSQS2 from Withania somnifera for squalene ...

Rhodosporidium sp. DR37: a novel strain for production of squalene in optimized cultivation conditions

open access: yesBiotechnology for Biofuels, 2021
Background Rhodosporidium strain, a well-known oleaginous yeast, has been widely used as a platform for lipid and carotenoid production. However, the production of squalene for application in lipid-based biofuels is not reported in this strain.

A Case for Anti‐IgE Vaccination

open access: yesAllergy, EarlyView.
ABSTRACT Immunoglobulin E (IgE) plays a central role in allergic diseases by binding to the high‐affinity receptor FcεRI on mast cells and basophils, where allergen‐induced crosslinking triggers potent inflammatory responses. Various mechanisms by which IgE responses are generated and functionally regulated remain elusive despite many years of research.

A systematic overexpression approach reveals native targets to increase squalene production in Synechocystis sp. PCC 6803

open access: yesFrontiers in Plant Science, 2023
Cyanobacteria are a promising platform for the production of the triterpene squalene (C30), a precursor for all plant and animal sterols, and a highly attractive intermediate towards triterpenoids, a large group of secondary plant metabolites ...
