title: Changes in Functional Network Output of Cocultured Ventral Horn Neurons

description: Co-cultures are a traditional method for studying the cellular properties of cell to cell interactions among different cell types. How network properties in these multicellular synthetic systems vary from monocultures are of particular interest. Understanding the changes in the functional output of these in vitro spiking neural networks can provide new insights into in vivo systems and how to develop biological system models that better reflect physiological conditions - something of paramount importance to the progress of synthetic biology. Culture models of spinal motor neurons have been customarily studied as a monoculture, and the overwhelming consensus is that in culture they are different in nature from their in vivo counterparts. We studied the electrophysiological properties of spinal ventral horn networks cocultured with myocytes or astrocytes using a 64 channel microelectrode array system to record extracellular voltage measurements. Significant differences were found between coculture types in metrics of spiking, bursting, and network bursting. Traditional culturing techniques involving a uniform cell type might not be the best way to functionally model in vivo neural networks. A synthetic ecosystem of various cell types is beneficial to replicating cell behavior in vitro, thus is a necessary refinement to the commonly used technique of cell culture. With a more physiological model system, hypotheses about interacting systems can be better addressed and the outcomes will have greater relevancy.

title: MassIVE MSV000085904 - GNPS - New Stylissamide L from the sponge Stylissa caribica
title: Feature-based molecular networking was used to re-examine the secondary metabolites in extracts of a very well studied marine sponge, Stylissa caribica, known to contain a large array of cyclic peptides and brominated alkaloids. The analysis revealed the presence in the sponge of 13 cyclic peptides that had never been detected in previous work and appeared to be new compounds. The most abundant one was isolated and shown to be a new proline-rich cyclic heptapetide that was called stylissamide L. Structure of stylissamide L, including the cis/trans geometry of the three proline residues, was determined by extensive NMR studies; the L configuration of the seven amino acid residues was determined using the Marfey method. Stylissamide L was tested for activity as a cell growth inhibitor and cell migration inhibitor on two cancer cell lines but, unlike other members of the stylissamide family, showed no significant activity. This approach showed that even a thoroughly studied species such as S. caribica may contain plenty of new chemistry that can be revealed if studied with the right tools.

title: hyperspectral albedo data collected at Ny Alesund

description: The produced dataset (in csv format) contains snow spectral albedo as measured the field activity carried out in Ny-Alesund (Svalbard Islands, Norway), where an unmanned apparatus was installed to provide continuous observations during the 2014 spring/summer period at the CNR Climate Change Tower, with the aim to deeply investigate changes in radiative characteristics during snow melting process. The survey covered the period from 25 May to 9 July 2014, when weather is highly variable and the Sun is constantly above the horizon. The continuous monitoring of the spectral albedo of the snowed surface was obtained coupling a tilting system with an ASD FieldSpec 3 portable spectroradiometer. The system was installed during the boreal spring nearly 8 m above the ground. The foreoptic applied to the fiber was a remote cosine receiver (RCR) with an hemispheric field of view that was fixed on the tilting device. The collected radiant energy was detected by the three spectroradiometers included in the Fieldspec with a wavelength range comprised between 350 and 2500 nm with a maximum spectral resolution of 1 nm. The spectral albedo measurements were acquired using the standard RCR mounted on the tilting system. Measurement cycles were performed <strong>every 15 min</strong>. Dark and optimization operations were executed every hours to estimate gain and spectral offset for each radiometer. Each rotation cycle was composed by a sequence of six downwelling irradiance spectra performed before and after three upwelling measurements, by completing the whole sequence in less than 3 min. All the stored spectra result from the average of ten fast acquisitions. Standard deviation associated to each triplet of spectra, provided information on sky stability, hence, indicating the possibility to perform accurate determination of the spectral albedo. For more details on experimental setup, acquisition and analysis procedures please refers to <strong><em>Salzano R., Lanconelli C., Salvatori R., Esposito G., Vitale V. (2016), Continuous monitoring of spectral albedo of snowed surfaces in Ny-Alesund, Rend. Fis. Acc. Lincei, 27 (Suppl 1):S137–S146 doi: 10.1007/s12210-016-0513-y</em></strong> Data set include 1728 spectra of snow albedo with a resolution of 1 nm from 350 nm to 2500 nm. They are stored in a unique file that contains columns of collected measurements in the following order: <strong>row 1</strong> wavelenght channels (w_350, w_351, .........w_2500); Time <strong>from row 2</strong> <strong>column 1</strong> Spectra number (albedo, alb, alb.1.....alb.1726) <strong>column 2</strong> snow spectral albedo at 350 nm <strong>......</strong> <strong>column 2501 </strong>snow spectral albedo at 2500 nm <strong>column 2502</strong> Date time (AAAA-MM-DD HH:MM) in UTC We have holes in the data, mainly due to instrument failures.
