Ultrasonographic criteria for the major salivary glands: a perspective for the application of new technologies [PDF]

, 2018
It emerges from the interesting recent article by David et al. (4) on high-resolution ultrasound is the first line examination for parotid gland diffuse disease and focal lesions, normally using grey-scale and color-Doppler ultrasound especially using

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Curriculum for the Management of Contrast Media Reactions, Contrast Induced Nephropathy & Nephrogenic Systemic Fibrosis

MedEdPORTAL, 2013
Radiologists supervising imaging studies using contrast media should have the necessary knowledge and skills to deal with adverse contrast media reactions and their appropriate management. The aim of this curriculum is to educate practicing radiologists,

A biochemical study on ameliorative effect of green tea (Camellia sinensis) extract against contrast media induced acute kidney injury. [PDF]

, 2013
INTRODUCTION Reactive oxygen species have been shown to be mediators of kidney injury and green tea polyphenols are potent-free radical scavengers.

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

FEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Contrast Media - A Review

Journal of Indian Academy of Oral Medicine and Radiology, 2003
When the clinical procedure alone fails to achieve accurate diagnosis, there is need to proceed from the simpler, more innocuous technique to other more complex invasive investigations. Radiography is one such simple procedure.

Single cis‐elements in brassinosteroid‐induced upregulated genes are insufficient to recruit both redox states of the BIL1/BZR1 DNA‐binding domain

FEBS Letters, EarlyView.
Phytohormone brassinosteroid‐induced gene regulation by the transcription factor BIL1/BZR1 involves redox‐dependent DNA‐binding alternation and interaction with the transcription factor PIF4. The reduced BIL1/BZR1 dimer binds preferred cis‐elements, while oxidation alters its oligomerization state and disrupts DNA‐binding ability.

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

FEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

FEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Asymptotic expansions for high-contrast elliptic equations

, 2012
In this paper, we present a high-order expansion for elliptic equations in high-contrast media. The background conductivity is taken to be one and we assume the medium contains high (or low) conductivity inclusions. We derive an asymptotic expansion with
