Free-living core body temperature monitoring using a wrist-worn sensor after COVID-19 booster vaccination: a pilot study.

Core body temperature (CBT) is a key vital sign and fever is an important indicator of disease. In the past decade, there has been growing interest for vital sign monitoring technology that may be embedded in wearable devices, and the COVID-19 pandemic has highlighted the need for remote patient monitoring systems. While wrist-worn sensors allow continuous assessment of heart rate and oxygen saturation, reliable measurement of CBT at the wrist remains challenging.

Placental plasticity in monochorionic twins: Impact on birth weight and placental weight.

Introduction: The knowledge about adaptive mechanisms of monochorionic placentas to fulfill the demands of two instead of one fetus is largely speculative. The aim of our study was to investigate the impact of chorionicity on birth weight and placental weight in twin pregnancies.

Methods: Forty Monochorionic (MC) and 43 dichorionic (DC) twin pregnancies were included in this retrospective study.

Aqueous dispersion and dielectrophoretic assembly of individual surface-synthesized single-walled carbon nanotubes.

The successful dispersion and large-scale parallel assembly of individual surface-synthesized large-diameter (1-3 nm) single-walled carbon nanotubes (SWNTs), grown by chemical vapor deposition (CVD), is demonstrated. SWNTs are removed from the growth substrate by a short, low-energy ultrasonic pulse to produce ultrapure long-term stable surfactant-stabilized solutions. Subsequent dielectrophoretic deposition bridges individual, straight, and long SWNTs between two electrodes.

Somatostatin receptor 1 selective analogues: 4. Three-dimensional consensus structure by NMR.

The three-dimensional NMR structures of six analogues of somatostatin (SRIF) are described. These analogues with the amino acid 4-(N-isopropyl)-aminomethylphenylalanine (IAmp) at position 9 exhibit potent and highly selective binding to human SRIF subtype 1 receptors (sst(1)). The conformations reveal that the backbones of these analogues have a hairpin-like structure similar to the sst(2)-subtype-selective analogues.
