Effects of red blood cell transfusion on cerebral hemodynamics of preterm neonates.

Significance: Anemia is a common problem in preterm neonates, and red blood cell transfusion (RBCT) is used to improve oxygen delivery. However, RBCT is associated with complications, although an increase in cerebral oxygenation has been documented, and no universally accepted biomarker for the need for transfusion (i.e.

Topical high concentration oxygen with hyaluronic acid: A safe and effective treatment for vaginal atrophy and sexual function improvement.

Background: Genitourinary syndrome of menopause (GSM) is a condition affecting many postmenopausal women. Among the available treatments, the vaginal natural oxygenation device (VNOD) is a new promising option.

Aim: To evaluate the safety and the effectiveness of vaginal high concentration (HC) oxygen (O) and hyaluronic acid (HA) in postmenopausal women with vaginal atrophy (VA).

Optical Tweezer Arrays of Erbium Atoms.

We present the first successful trapping of single erbium atoms in an array of optical tweezers. Using a single narrow-line optical transition, we achieve deep cooling for direct tweezer loading, pairwise ejection, and continuous imaging without additional recoil suppression techniques. Our tweezer wavelength choice enables us to reach the magic trapping condition by tuning the ellipticity of the trapping light.

Heat stress reduces stomatal numbers in Ginkgo biloba: Implications for the stomatal method of palaeo-atmospheric [CO] reconstruction during episodes of global warming.

The stomata of fossil plants are commonly used as proxies to reconstruct palaeo-atmospheric carbon dioxide concentrations (palaeo-[CO]). Stomatal reconstruction of palaeo-[CO] during global greenhouse periods or episodes of global warming, are particularly important to our understanding of the role of CO as a climate system driver. However, the efficacy of the 'stomatal method' for palaeo-[CO] reconstruction depends upon the strength of the inverse relationship between stomatal number and the [CO] in which the leaf developed.
