Application of the tandem thionium/N-acyliminium ion cascade toward heterocyclic synthesis

Journal of the Brazilian Chemical Society, 2001
Many structurally diverse heterocyclic compounds can be easily accessed via the domino Pummerer/cycloaddition/N-acyliminium ion cyclization cascade.

Opening and Closing in Tandem

JACC: Cardiovascular Interventions, 2016
The rationale and sequencing of opening and closing structures has been well studied in mechanical sciences and disciplines. The report by Attinger-Toller et al. [(1)][1] in this issue of JACC: Cardiovascular Interventions extends this conversation to the specific medical field of aortic stenosis (

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

White organic light-emitting diode (OLED) microdisplay with a tandem structure

Journal of Information Display, 2019
Microdisplay is a key technology for realizing augmented reality (AR) and mixed reality (MR) devices, which have attracted much attention of late. Even though the operating voltage in the tandem structure is higher than that in the single structure, 2 ...

The evolution of creaky voice use in read speech by native-French and native-English speakers in tandem: a pilot study

Anglophonia, 2019
Creaky voice is a non-modal (non-neutral) speech feature occurring both at the segmental and suprasegmental levels of languages. It also performs paralinguistic, stylistic, sociolinguistic and extra-linguistic functions. It has been reported as prevalent

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Observation Strategies for TanDEM-X and Tandem-L [PDF]

, 2021
TanDEM-X is a unique mission to derive digital elevation models (DEMs) with two SAR satellites in orbit since 2007 and 2010. Being still in good shape, an update of the global DEM, called "Change DEM", is currently in acquisition. DLR is also pushing for the time after TanDEM-X with Tandem-L, a proposal for a sophisticated satellite-duo operating in L ...

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

PERCENTILE OF TANDEM QUEUE

Journal of the Operations Research Society of Japan, 1985
Quite often, there are tandem queue systems the service facilities of which are serially linked; for example, computer systems that consist of two stages. In the general cases, the total time spent in the system corresponds to the response time. However, customers have a greater interest in upper deviation of the time than in the mean value as a ...

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins

FEBS Open Bio, EarlyView.
Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...
