Technological innovation can drive scientific inquiry by allowing researchers to answer questions that were once out of reach. Eukaryotic mRNA synthesis was not so long ago thought of as a deterministic, sequential process in which transcriptional regulators and general transcription factors assemble in an orderly fashion into chromatin to, ultimately, activate RNA polymerase II. Advances in fluorescence microscopy techniques have revealed a much more complex scenario, wherein transcriptional regulators dynamically engage with chromatin in a more stochastic, probabilistic way.

Electronic address:

In subjects implanted with intracranial electrodes, we use two different stories involving the same person (or place) to evaluate whether and to what extent context modulates human single-neuron responses. Nearly all neurons (97% during encoding and 100% during recall) initially responding to a person/place do not modulate their response with context. Likewise, nearly none (<1%) of the initially non-responsive neurons show conjunctive coding, responding to particular persons/places in a particular context during the tasks.

This paper investigates gender differences in the short- and longer-term impacts of the COVID-19 pandemic on employment status in Argentina. Using individual cross-sectional and panel data from household surveys, we compare employment status (inactive, unemployed, self-employed, or employed, distinguishing between the formal and informal sectors) before, immediately after, and a year after the pandemic. We examine how gender intersects with education and age in affecting employment status transitions and the extent to which COVID-19 deepened gender, educational, and age inequalities.

Diagnosis of Carotid Fibromuscular Dysplasia Using Transoral Ultrasound in the Intensive Care Unit.

J Clin Ultrasound

January 2025

Argentinian Critical Care Ultrasonography Association (ASARUC), Buenos Aires, Argentina.

Fibromuscular dysplasia (FMD) is a rare, non-atherosclerotic vascular disease affecting medium to large arteries, especially the renal and internal carotid arteries (ICAs). The string-of-beads appearance, indicative of alternating areas of stenosis and dilatation, is a key imaging feature typically observed in the distal ICAs. Diagnosing FMD in critically ill patients poses challenges due to the risks associated with traditional imaging methods such as computed tomography angiography (CTA), magnetic resonance angiography, and digital subtraction angiography.
