The surface accessibility of α-bungarotoxin monitored by a novel paramagnetic probe [PDF]

arXiv, 2011
The surface accessibility of {\alpha}-bungarotoxin has been investigated by using Gd2L7, a newly designed paramagnetic NMR probe. Signal attenuations induced by Gd2L7 on {\alpha}-bungarotoxin C{\alpha}H peaks of 1H-13C HSQC spectra have been analyzed and compared with the ones previously obtained in the presence of GdDTPA-BMA. In spite of the different

In heart failure, echocardiographic parameters of right ventricular function are powerful tools to predict renal failure

ESC Heart Failure, EarlyView.
Abstract Background Chronic kidney disease (CKD) has a high prevalence in patients with heart failure (HF) and is associated with prolonged hospitalization, increased need for intensive care and mortality. There is an urgent need to identify factors that influence the interaction between heart and kidney disorders, often described as cardiorenal ...

Non‐Classical Nitrogen Promoters for Rhodium‐Catalyzed Reductive Hydroformylation: New Efficient Way to Access Polyols From Linseed Oil

European Journal of Lipid Science and Technology, EarlyView.
The reductive hydroformylation of linseed oil was carried out using a rhodium precursor associated with various nitrogen derivatives such as pyridines, imidazoles, trialkylamines, amidines, and guanidines. ABSTRACT The reductive hydroformylation reaction of polyunsaturated linseed oil using a rhodium precursor associated with a nitrogen compound from ...

E‐cigarette use and the relationship to smoking among Aboriginal and Torres Strait Islander and non‐Indigenous Australian Secondary Students, 2017

Australian and New Zealand Journal of Public Health, Volume 46, Issue 6, Page 807-813, December 2022., 2022
Abstract Objective: Estimate the prevalence of e‐cigarette use (vaping) among Aboriginal and Torres Strait Islander adolescents and explore the relationship between vaping and tobacco use. Methods: N=18,199 students aged 12–17 years (n=1,097 Aboriginal and Torres Strait Islander) participating in the 2017 Australian Secondary Students’ Alcohol and Drug

Monod-Wyman-Changeux Analysis of Ligand-Gated Ion Channel Mutants [PDF]

arXiv, 2017
We present a framework for computing the gating properties of ligand-gated ion channel mutants using the Monod-Wyman-Changeux (MWC) model of allostery. We derive simple analytic formulas for key functional properties such as the leakiness, dynamic range, half-maximal effective concentration, and effective Hill coefficient, and explore the full spectrum

Nitrosamines as nicotinic receptor ligands [PDF]

Life Sciences, 2007
Nitrosamines are carcinogens formed in the mammalian organism from amine precursors contained in food, beverages, cosmetics and drugs. The potent carcinogen, NNK, and the weaker carcinogen, NNN, are nitrosamines formed from nicotine. Metabolites of the nitrosamines react with DNA to form adducts responsible for genotoxic effects. We have identified NNK

Recent Advances in the α‐Hydrazination (α‐Amination) of Carbonyl Compounds

European Journal of Organic Chemistry, EarlyView.
In recent years, notable progress has been achieved in the α‐hydrazination (α‐amination) of carbonyl compounds, especially in the direct asymmetric electrophilic α‐hydrazination with dialkyl azodicarboxylates. This review summarizes all the methods that appeared over the past decade, categorized based on the type of the reactive chiral intermediate ...

Vaping product access and use among 14–17‐year‐olds in New South Wales: a cross‐sectional study

Australian and New Zealand Journal of Public Health, Volume 46, Issue 6, Page 814-820, December 2022., 2022
Abstract Objectives: We assessed access to vaping products and types of products used and the factors associated with vaping and smoking among young people in the state of New South Wales (NSW), Australia. Methods: A cross‐sectional survey was conducted with a sample of 721 young people aged 14 to 17 years from NSW recruited through online panels ...

Impaired neurovascular coupling in the APPxPS1 mouse model of Alzheimer’s disease [PDF]

arXiv, 2019
The tight coupling between neuronal activity and the local increase of blood flow termed neurovascular coupling is essential for normal brain function. This mechanism of regulation is compromised in Alzheimer's Disease (AD). In order to determine whether a purely vascular dysfunction or a neuronal alteration of blood vessels diameter control could be ...
