Capsaicin-Induced Ca2+ Influx and Constriction of the Middle Meningeal Artery [PDF]

open access: yes, 2014
Research in the past on transient receptor potential cation channel subfamily V member 1 (TRPV1) has been limited to mainly nervous tissue TRPV1 because of the channel’s role in pain perception.

Pinning and depinning of a classic quasi-one-dimensional Wigner crystal in the presence of a constriction

open access: yes, 2005
We studied the dynamics of a quasi-one-dimensional chain-like system of charged particles at low temperature, interacting through a screened Coulomb potential in the presence of a local constriction.

Discontinuous resistance change and domain wall scattering in patterned NiFe wires with a nanoconstriction [PDF]

open access: yes, 2004
A nonlinear current-voltage (I-V) characteristic was observed in patterned NiFe wires with a central "bow-tie" point contact constriction. By passing a dc current through the wire, a sharp resistance drop was obtained for current densities in the range ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Comparative effectiveness of drugs used to constrict the patent ductus arteriosus: a secondary analysis of the PDA-TOLERATE trial (NCT01958320). [PDF]

open access: yes, 2019
ObjectiveTo evaluate the effectiveness of drugs used to constrict patent ductus arteriosus (PDA) in newborns < 28 weeks.MethodsWe performed a secondary analysis of the multi-center PDA-TOLERATE trial (NCT01958320).

Microscopic Theory of Josephson Mesoscopic Constrictions

open access: yes, 1993
We present a microscopic theory for the d.c. Josephson effect in model mesoscopic constrictions. Our method is based on a non-equilibrium Green function formalism which allows for a self-consistent determination of the order parameter profile along the ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Bilateral popliteal entrapment syndrome in a young athlete diagnosed with ultrasound

open access: yesRadiology Case Reports, 2022
Popliteal artery entrapment syndrome (PAES) occurs when the popliteal artery is compressed by abnormally developed or hypertrophied muscles adjacent to the popliteal fossa.

Acoustoelectric effects in quantum constrictions

open access: yes, 1997
A dc current induced in a quantum constriction by a traveling acoustic wave (or by non-equilibrium ballistic phonons) is considered. We show that in many important situations the effect is originated from acoustically-induced scattering between the ...

Ego Constriction [PDF]

open access: yesThe American Journal of Psychoanalysis, 2004
The terms ego constriction, ego inhibition, and ego restriction have not been clearly differentiated in their usage in the literature. In this paper a rationale for "ego constriction" as an entity distinct from both ego inhibition and ego restriction is given, despite its clear similarities to each.
