First evidence for an invol- vement of this region in the aetiology of the disease was the identification of maternal 11p15 duplications in growth retarded patients. Four out of these six cases showed SRS features in addition to intrauterine and Table 2 Frequencies of the different types of (...
And just wanted to know there is a number on the bottom of one of the items and it says "1211" can you tell me what these markings mean for further identification of other items as well? I am starting to get back into silver items again but I don't know much about any of the ...
(b) Other items requiring export licence: In addition to specific rules relating to endangered or protected species, export licenses are required in relation to items manufactured or produced more than 50 years before the date of export outside the UK and/or the Europea...
The spike isotopic composition was selected to be 𝐴109𝑠𝑝~1Asp109~1 in order to minimize its contribution to the m/z = 107, which is used for NP identification. This permits us to improve the LODsize. For the same reason, the concentration of the spike would need to be kept su...
[13]. Nowadays, SERS has the characteristics of selectivity, rapidity, simplicity, and specificity, and has been widely used in the fields of molecular identification [1], drug monitoring, medical diagnosis, biological detection [5,14], water contaminants [15,16], health care [17,18], food ...
Here, major techniques for AgNP chemical synthesis and physical deposition have been discussed and reviewed to date. Recent developments in the field of controlled synthesis and the assembly of Ag nanostructures involving nanoskiving and DNA origami are still motivating researchers to unravel the new ...
This research marks the pioneering effort in the synthesis of AgNPs utilizing S. greggii and S. blepharophylla extracts, coupled with a comprehensive evaluation of their antimicrobial, antioxidant, and antidiabetic activities. The unique contribution of this study lies in its exploration of the ...
