Medical Microrobots In article number 2109741, Metin Sitti and co-workers report FePt-covered Janus microrollers that travel in the blood stream to reach tumor site. The have a special magnetic alloy with an L10 crystal structure enables locomotion, imaging, biocompatibility.

INTRODUCTION High levels of sound have several negative effects, such as noise-induced hearing loss and delayed growth and development, on premature infants in neonatal intensive care units (NICUs). In order to reduce sound levels, they should first be measured. This study was performed to assess sound levels and determine sources of noise in the NICU of Alzahra Teaching Hospital (Tabriz, Iran)...

A subcellular fraction (P3) from Aplysia is enriched in synaptosomes (Chin et al., 1988) and is capable of accumulating 5-HT and choline. At an external 3H-5-HT concentration of 1.8 microM, the P3 fraction took up 0.12 nmol/mg protein in 30 min. Uptake was dependent on external Na+. Electron microscopic autoradiography showed that much of the accumulated 3H-5-HT is localized to synaptosomes. At...

BACKGROUND The main objective of this randomized, double-blind, parallel-group, comparative study was to assess the efficacy and safety of rupatadine 10 mg (R10) and 20 mg (R20) administered once-daily for two weeks compared with those of loratadine 10 mg (L10) in the treatment of seasonal allergic rhinitis (SAR). METHODS A total of 339 SAR patients were randomized to receive R20 (111 patient...

The milk/solid feed intake pattern and digestive capacity were compared in two groups of young rabbits reared between 16 and 32 days in litters of four (L4 group, n = 18 litters) or ten pups (L10, n = 20) in order to modulate milk availability. Compared to the L4 group, rabbits in the L10 group presented a lower milk intake (22.3 versus 28.8 g x day(-1)) and a higher solid feed intake (12.9 ver...

Thirteen alleles (L, L1 to L11, and LH) from the flax L locus, which encode Toll/interleukin-1 receptor homology-nucleotide binding site-leucine-rich repeat (TIR-NBS-LRR) rust resistance proteins, were sequenced and compared to provide insight into their evolution and into the determinants of gene-for-gene resistance specificity. The predicted L6 and L11 proteins differ solely in the LRR region...

The inability to describe charge redistribution from regions I to II at the high level of theory imposes limitations on the general applicability of the our own N-layered integrated molecular orbital and molecular mechanics (ONIOM) method. In this report, we exploit the most inexpensive components of an ONIOM QM:QM calculation to provide a new method which has the ability to describe such charg...

We report a facile synthesis of hard magnetic L10-FePtAu nanoparticles by coreduction of Fe(acac)3, Pt(acac)2 (acac = acetylacetonate) and gold acetate in oleylamine. In the current reaction condition, NP sizes are controlled to be 5.5 to 11.0 nm by changing the amount of Au doping. When the Au composition in the NPs is higher than 14%, the hard magnetic NPs are directly obtained without any an...
