Sex differences in brain activation patterns with mental stress in patients with coronary artery disease

ConclusionMen and women with CAD show differences in responses to stress in brain limbic areas that regulate emotion, and these functional responses differ by MSI status. Our results suggest that the cingulate gyrus may be involved in sex differences in MSI.

ConclusionThese results indicate that A. farnesiana pods contain nematocidal compounds and might be promising natural anthelmintic agents against H. contortus. This leguminous plant could be used as a nutraceutical food source for the control of gastrointestinal nematodes in small ruminants.Graphical abstract

ConclusionsThe sagittal skeletal relationship showed no influence on the alveolar thickness or height, even if dental compensation was present. Hyperdivergent individuals showed smaller alveolar thicknesses and heights than hypodivergent individuals.RésuméObjectifL’os alvéolaire entourant les incisives mandibulaires donne les limites dans l’inclinaison buccolinguale pouvant être atteintes avec un traitement. L’objectif de cette étude était d’évaluer l’épaisseur et la hauteur alvéolaires antérieures mandibulaires chez des suje...

Transthyretin amyloid deposition is present in 17% of autopsies of patients with heart failure and a preserved ejection fraction (HFpEF). 99mTechnetium-pyrophosphate scintigraphy (99mTc-PYP) is sensitive and specific to diagnose cardiac transthyretin amyloid deposition (ATTR). The prevalence of ATTR by 99mTc-PYP was evaluated along with echocardiographic parameters in patients with HFpEF. One-hundred consecutive patients with HFpEF, who had 99mTc-PYP, were retrospectively evaluated. Echocardiographic variables were analyzed to compare patients with positive versus negative ATTR infiltration. Myocardial ATTR was present in ...

We report on the advance of freeze-dried mucoadhesive orodispersible tablets (ODTs) loaded with prilocaine (PRC) and lidocaine (LDC) hydrochlorides, aiming to promote noninvasive buccal anesthesia. The influences of combining biocompatible polymers (pullulan and HPMC K100 LV) and a blend of surfactants (oleic acid, polysorbate 80 and propylene glycol) acting as chemical enhancers on the permeation of such drugs through the esophageal porcine epithelium and in vitro mucoadhesion were investigated. The ODTs were also characterized in terms of average weight, thickness, pH, drug content, in vitro release, thermal behavior and...

In this study, the microstructure characterization, mechanical properties and degradation behaviors of the Mg-xZn-0.1Mn-0.2Ca alloys with various Zn contents were analyzed via the polarization test, electrochemical impedance spectroscopy and the static immersion measurements. Meantime, the surface film layer features and the phase constitutions of the degradation production were characterized via the confocal laser scanning microscopy (3D/CLSM) and scanning electron microscopy. The results indicated that the more secondary phases appeared and the grain sizes were remarkably refined with the further addition of Zn, such as ...

Park, Hanzhang LuAbstractCerebrovascular reactivity (CVR) mapping using CO2-inhalation can provide important insight into vascular health. At present, blood-oxygenation-level-dependent (BOLD) MRI acquisition is the most commonly used CVR method due to its high sensitivity, high spatial resolution, and relatively straightforward processing. However, large variations in CVR acr...
