Inducible nitrogen oxide synthase (iNOS) is the primary contributor of the overproduction of nitric oxide and its inhibitors have been actively sought as effective anti-inflammatory agents. In this study, we prepared 70% ethanol extracts from 81 Chinese herbs. These extracts were subsequently evaluated for their effect on nitrogen oxide (NO) production and cell growth in LPS/IFNγ-costimulated a...

Three new neo-clerodane diterpenoids, one C-16 epimeric pair, scutegalerins C and D, and scutegalerin E, together with the known scutaltisin B, were isolated from the acetone extractof the aerial parts of Scutellaria galericulata. The chemical structures of the new compounds were elucidated by spectroscopic techniques and a comparison with data of similar compounds as (13S,16R,19S)-6a-acetoxy-2...

This paper proposes a new routing algorithm to facilitate communication in highly mobile wireless ad-hoc networks for motorway environments with no physical infrastructure which undergo frequent topological changes. This new reactive routing algorithm for inter-vehicular communication is based on location information in which the source node ascertains the position of its communication partner ...

Antarctic conditions demand that wireless sensor nodes are operational all year round and that they provide a large communication range of several tens of kilometers. LoRa technology operating in sub-GHz frequency bands implements these wireless links with minimal power consumption. The employed chirp spread spectrum modulation provides a large link budget, combined with the excellent radio-wav...

Bistatic synthetic aperture radar (SAR) enables new defense as well as environmental applications where the characteristics of the bistatic reflectivity can be exploited. Experimental results obtained with microwave systems have been reported but not much is published using lower frequencies (< 1GHz). FOI has been active in this part of the electromagnetic spectrum for many years with the devel...
