Rhodotorula mucilaginosa: a new potential human pathogen found in the ciliate Paramecium bursaria.

Ciliates often form symbiotic associations with other microorganisms, both prokaryotic and eukaryotic. We are now starting to rediscover the symbiotic systems recorded before molecular analysis became available. Here, we provide a morphological and molecular characterization of a symbiotic association between the ciliate Paramecium tritobursaria and the yeast Rhodotorula mucilaginosa (syn.

Registration of activity of a single molecule of horseradish peroxidase using a detector based on a solid-state nanopore.

This work demonstrates the use of a solid-state nanopore detector to monitor the activity of a single molecule of a model enzyme, horseradish peroxidase (HRP). This detector includes a measuring cell, which is divided into cis- and trans- chambers by a silicon nitride chip (SiN structure) with a nanopore of 5 nm in diameter. To entrap a single HRP molecule into the nanopore, an electrode had been placed into the cis-chamber; HRP solution was added into this chamber after application of a negative voltage.

A case report of a combined implantation technique of a cardioverter-defibrillator in an infant with long QT syndrome type 8 (Timothy's syndrome).

We present a case of successful implantation of a cardioverter-defibrillator (ICD) using combined technique in a child with Timothy's syndrome. Due to high risk of sudden cardiac death (SCD) such patients often need ICD for primary or secondary prevention but implantation technique in young children remains controversial. The subcutaneous cardioverter-defibrillators could be an option in some cases, however, reliable cardiac pacing should be implemented for patients with bradyarrhythmias.

Photocurrent Spectroscopy of Dark Magnetic Excitons in 2D Multiferroic NiI.

Two-dimensional (2D) antiferromagnetic (AFM) semiconductors are promising components of opto-spintronic devices due to terahertz operation frequencies and minimal interactions with stray fields. However, the lack of net magnetization significantly limits the number of experimental techniques available to study the relationship between magnetic order and semiconducting properties. Here, they demonstrate conditions under which photocurrent spectroscopy can be employed to study many-body magnetic excitons in the 2D AFM semiconductor NiI.
