Laser-induced transient magnons in SrIrO throughout the Brillouin zone.

Although ultrafast manipulation of magnetism holds great promise for new physical phenomena and applications, targeting specific states is held back by our limited understanding of how magnetic correlations evolve on ultrafast timescales. Using ultrafast resonant inelastic X-ray scattering we demonstrate that femtosecond laser pulses can excite transient magnons at large wavevectors in gapped antiferromagnets and that they persist for several picoseconds, which is opposite to what is observed in nearly gapless magnets. Our work suggests that materials with isotropic magnetic interactions are preferred to achieve rapid manipulation of magnetism.

Association Between Pulsatile Components of Blood Pressure and Severe Tooth Loss in Rural Ecuador: The Three Villages Study.

Arterial hypertension has been associated with severe tooth loss, but differential associations with individual components of blood pressure (BP) have scarcely been investigated. We assessed the independent associations between pulsatile/steady components of BP and severe tooth loss in community-dwelling adults residing in 3 rural Ecuadorian villages. Individuals aged ≥40 years living in Atahualpa, El Tambo, and Prosperidad were identified during door-to-door surveys.

The association between aortic arterial stiffness, carotid intima-media thickness and carotid plaques in community-dwelling older adults: A population-based study.

Objective: Information on the associations among arterial stiffness, carotid intima-media thickness (cIMT) and carotid plaques as biomarkers of atherosclerosis is limited in diverse populations. We aimed to assess whether aortic pulse wave velocity (aPWV) - as a surrogate of arterial stiffness - is associated with increased cIMT and the presence of carotid plaques in a cohort of older adults of Amerindian ancestry.

Methods: Atahualpa residents aged ≥60 years ( = 320) underwent aPWV determinations, and carotid ultrasounds for cIMT and plaque assessment.

Cerebral small vessel disease score and atherosclerosis burden - A population study in community-dwelling older adults.

Objective: Cerebral small vessel disease (cSVD) and large artery atherosclerosis (LAA) are related to different pathogenetic mechanisms. However, relationships between single biomarkers of cSVD and LAA affecting isolated vascular beds have been reported. Using the Atahualpa Project cohort, we aimed to assess the association between cSVD score categories and LAA burden in community-dwelling older adults.

Cardiovascular Health Status Among Community-Dwelling Ecuadorian Natives Living in Neighboring Rural Communities: The Three Villages Study.

Knowledge of cardiovascular health (CVH) status in rural communities is essential to implement cost-effective strategies aimed to address the growing burden of cardiovascular diseases in these settings. Here, we report on the CVH status and health metrics of 1508 community-dwellers aged ≥ 40 years in three neighboring rural villages of Coastal Ecuador (Atahualpa, El Tambo, and Prosperidad). According to the American Heart Association, a poor CVH status is designated when at least one cardiovascular health metric is in the poor range.

Evidence for short-range-ordered charge stripes far above the charge-ordering transition in La1.67Sr0.33NiO4.

The temperature evolution of structural effects associated with charge order (CO) and spin order in La1.67Sr0.33NiO4 has been investigated using neutron powder diffraction.
