Approximation of Dirac operators with δ‐shell potentials in the norm resolvent sense, II: Quantitative results

open access: yesMathematische Nachrichten, EarlyView.
Abstract This paper is devoted to the approximation of two‐ and three‐dimensional Dirac operators HV∼δΣ$H_{\widetilde{V} \delta _\Sigma }$ with combinations of electrostatic and Lorentz scalar δ$\delta$‐shell interactions in the norm resolvent sense. Relying on results from Behrndt, Holzmann, and Stelzer‐Landauer [Math. Nachr.

Orthosteric and Allosteric Ligands of Nicotinic Acetylcholine Receptors for Smoking Cessation

open access: yesFrontiers in Molecular Neuroscience, 2015
Nicotine addiction, the result of tobacco use, leads to over six million premature deaths world-wide, a number that is expected to increase by a third within the next two decades.

Bioinformatics‐Driven Design and Evaluation of Recombinant Multi‐Epitope Immunogens Derived From Snake Venom Toxins as Potential Antivenom Candidates

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Snakebite envenomation is a major public health concern, particularly in low‐ and middle‐income regions where access to safe and effective antivenoms is limited. Traditional antivenoms, derived from immunization with crude venom, often trigger adverse reactions and lack specificity against key venom components.

Distinctive single-channel properties of α4β2-nicotinic acetylcholine receptor isoforms.

open access: yesPLoS ONE, 2019
Central nervous system nicotinic acetylcholine receptors (nAChR) are predominantly of the α4β2 subtype. Two isoforms exist, with high or low agonist sensitivity (HS-(α4β2)2β2- and LS-(α4β2)2α4-nAChR). Both isoforms exhibit similar macroscopic potency and

Nicotine-Mediated Regulation of Nicotinic Acetylcholine Receptors in Non-Small Cell Lung Adenocarcinoma by E2F1 and STAT1 Transcription Factors. [PDF]

open access: yesPLoS ONE, 2016
Cigarette smoking is the major risk factor for non-small cell lung cancer (NSCLC), which accounts for 80% of all lung cancers. Nicotine, the addictive component of tobacco smoke, can induce proliferation, migration, invasion, epithelial-mesenchymal ...

A novel α-conotoxin, PeIA, cloned from Conus pergrandis, discriminates between Rat α9α10 and α7 nicotinic cholinergic receptors [PDF]

open access: yes, 2005
The α9 and α10 nicotinic cholinergic subunits assemble to form the receptor believed to mediate synaptic transmission between efferent olivocochlear fibers and hair cells of the cochlea, one of the few examples of postsynaptic function for a non-muscle ...

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Nicotinic Acetylcholine Receptor Subtype Alpha-9 Mediates Triple-Negative Breast Cancers Based on a Spontaneous Pulmonary Metastasis Mouse Model

open access: yesFrontiers in Cellular Neuroscience, 2017
Triple-negative breast cancer (TNBC) subtype is associated with poor prognosis and a high risk of recurrence-related death in women. Despite the aggressiveness of TNBCs, targeted TNBC therapy is not yet available in the clinic. To overcome this challenge,

Venomous secretions from marine snails of the Terebridae family target acetylcholine receptors [PDF]

open access: yes, 2013
Venoms from cone snails (Conidae) have been extensively studied during the last decades, but those from other members of the suborder Toxoglossa, such as of Terebridae and Turridae superfamilies attracted less interest so far. Here, we report the effects
