Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Growth of Ti-C nanocomposite films by reactive high power impulse magnetron sputtering under industrial conditions

Surface and Coatings Technology, 2012
Titanium carbide (TiC) films were deposited employing high power impulse magnetron sputtering (HiPIMS) and direct current magnetron sputtering (DCMS) in an Ar-C2H2 atmosphere of various composition ...

Hardware and power management for high power impulse magnetron sputtering

, 2019
The work that led to the development of the HiPIMS technique was initiated at the Moscow Engineering and Physics Institute (MEPhI) in the late 1960s, where high power pulses were applied to diode sputter sources.

Differential expression of cancer‐related genes supports prediction of poor response to first‐line treatments in T‐ALL pediatric patients with high minimal residual disease

Molecular Oncology, EarlyView.
In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...

Effect of Enhancement Material on the Performance of Ground Electrodes Under Impulse Conditions

IEEE Access
Among the factors that affect the soil resistivity is the chemical content in soil, where the ionic conduction is expectedly increased and the soil resistivity is reduced.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Impulse ageing of polymeric materials

, 2011
Impulse over-voltage is a common phenomenon in electric power systems. A switching impulse is created by a switching surge or local fault while a lightning impulse is due to direct lightning strike to high voltage plant such as an overhead line.

[2+2] and [2+1] cycloaddition of myrcene for synthesis of highly strained bio-fuels with high density and high impulse

Energetic Materials Frontiers
Developing bio-fuels provides a sustainable strategy to reduce the dependence on finite fossil fuels. But biomass-based fuel molecules usually lack strained structure, resulting in undesirable density and impulse for aerospace applications.

"Effects of electrohydroimpulse discharges on the crushing of the natural mineral quartz "

Eurasian Physical Technical Journal, 2019
Electro-hydro-impulse (high-current discharge in water) also belongs to the technologies using strong impulse currents. With a powerful pulsed electric discharge between the electrodes placed in the liquid, an electro-hydraulic effect occurs.

MIRaGe: Multichannel Database Of Room Impulse Responses Measured On High-Resolution Cube-Shaped Grid In Multiple Acoustic Conditions

CoRR, 2019
We introduce a database of multi-channel recordings performed in an acoustic lab with adjustable reverberation time. The recordings provide information about room impulse responses (RIR) for various positions of a loudspeaker. In particular, the main positions correspond to 4104 vertices of a cube-shaped dense grid within a 46x36x32 cm volume.
