Formation of hollow silver nanoparticles under irradiation with ultrashort laser pulses.

We have studied the formation of cavities in spherical silver nanoparticles embedded in silica, irradiated with fs laser pulses that produce an intense electronic excitation. Experimentally determined aspect ratio, i.e.

Stabilizing selection and adaptation shape and gene expression variation in .

An outstanding question in the evolution of gene expression is the relative influence of neutral processes versus natural selection, including adaptive change driven by directional selection as well as stabilizing selection, which may include compensatory dynamics. These forces shape patterns of gene expression variation within and between species, including the regulatory mechanisms governing expression in and . In this study, we interrogate intraspecific gene expression variation among seven wild strains, with varying degrees of genomic divergence from the reference strain N2, leveraging this system's unique advantages to comprehensively evaluate gene expression evolution.

EPIDEMIOLOGY OF DEPRESSIVE STATES IN ACUTE AND CHRONIC CONDITIONS.

Depression is the only silent cause that mainly affects the adult population and manifests itself in this case in 4% of the world population. However, more than three quarters of those affected belong to land in urbanization without receiving any type of treatment; a situation that represents a gap in access to mental health services. Now, the hallucinatory relationships mean that this condition has a high level of competition with chronic diseases such as HIV, diabetes, lung disease, asthma, arthritis, angina pectoris and cerebral palsy; Assimilation, it has been detected that patient with affective disorders such as coronary syndrome, inflammation, malnutrition, pain, stress and even critical stages of COVID-19 infection act as risk factors for the development of the disease.

Atomistic study of CoCrCuFeNi high entropy alloy nanoparticles: Role of chemical complexity.

High entropy alloy nanoparticles are envisaged as one of the most interesting materials compared to monoatomic materials due to their modulated properties in terms of their convenient surface-to-volume ratio. However, studies are still missing to unveil how composition or nanoparticle size can influence nanoparticle morphology. Based on molecular dynamics simulations, we perform a structural characterization as a function of nanoparticle size and the chemical composition of high entropy alloy nanoparticles subject to multiple annealing cycles.

Advanced Breast Cancer Guidelines in Latin America: Assessment, Adaptation, and Implementation of Fifth Advanced Breast Cancer Consensus Guidelines.

Purpose: As the fifth international consensus on advanced breast cancer (ABC5) established guidelines for the management of this disease, the aim of this article was to present the applicability of the consensus recommendations and to generate knowledge to improve access.

Methods: Sixty-one recommendation statements were selected and discussed by 15 breast cancer experts from Latin America (LA). After the discussion, the level of consensus was determined through a vote.
