PIEZO2 in somatosensory neurons controls gastrointestinal transit.

The gastrointestinal tract is in a state of constant motion. These movements are tightly regulated by the presence of food and help digestion by mechanically breaking down and propelling gut content. Mechanical sensing in the gut is thought to be essential for regulating motility; however, the identity of the neuronal populations, the molecules involved, and the functional consequences of this sensation are unknown.

Aberration calibration and correction with nano-scatterers in digital holographic microscopy for semiconductor metrology.

Overlay metrology measures pattern placement between two layers in a semiconductor chip. The continuous shrinking of device dimensions drives the need to explore novel optical overlay metrology concepts that can address many of the existing metrology challenges. We present a compact dark-field digital holographic microscope that uses only a single imaging lens.

Cardiovascular fluctuations and transfer function analysis in stable preterm infants.

To examine the baroreceptor reflex function, a beat-to-beat analysis between systolic blood pressure (SBP) and R-R interval fluctuations was studied in 10 stable appropriate-for-gestational age preterm infants (range, 27.2-33.7 wk) in the first postnatal week during quiet sleep.

Supraventricular escape rhythms during transient episodes of bradycardia in preterm infants.

Objective: To evaluate the origin of transient episodes of sinus bradycardia, atrial escape rhythm, and atrioventricular nodal escape rhythm in preterm infants.

Material And Methods: The study was observational, and was carried out in a third level neonatal intensive care unit. We studied 19 spontaneously breathing infants born healthy but prior to term, the examinations being carried out between the ages of 3 and 28 days.

[Two neonates with severe rhesus antagonism inspite of low values in recent tests of antibody dependent cellular cytotoxicity (ADCC)].

In two female newborn babies severe haemolytic disease of the newborn developed due to anti-RhD antibodies of the mother. In both cases the results of the last antibody-dependent cellular cytotoxicity (ADCC) test had been < 10% (two and three weeks before parturition respectively) making haemolytic disease unlikely. The ADCC test is used to determine the destructive power of the responsible maternal antibodies.
