Torsional suspension system for testing space structures [PDF]

, 1991
A low frequency torsional suspension system for testing a space structure uses a plurality of suspension stations attached to the space structure along the length thereof in order to suspend the space structure from an overhead support.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Mixed Gold(I)−Gold(III) Complexes with Bridging Selenido Ligands. Theoretical Studies of the Gold(I)−Gold(III) Interactions

Organometallics, 2001
The gold(I) compounds [Se(AuPPh3)2] and [Se{Au2(μ-dppf)}] (dppf = 1,1‘-bis(diphenylphosphino)ferrocene) react with 1 and 2 equiv of [Au(C6F5)3OEt2] to give the mixed gold(I)−gold(III) derivatives [...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

A novel utilization of sugarcane bagasse-derived ash to reductively remove gold(III) to gold metal: Energetics, kinetics and mechanism studies

Case Studies in Chemical and Environmental Engineering
A new method utilizing sugarcane bagasse-derived ash (SB-dA) to remove and convert gold(III) to valuable noble gold metal has been developed. The SB-dA was purified with a mixed solution of 0.1 mol/L HCl and 0.3 mol/L HF, followed by 3 mol/L HNO3 ...

Dual versus monotherapy with bronchodilators in GOLD group B COPD patients according to baseline FEV1 level: a patient-level pooled analysis of phase-3 randomized clinical trials

Respiratory Research, 2021
Background Which patients should receive dual therapy as initial treatment for chronic obstructive pulmonary disease (COPD) is only loosely defined. We evaluated if a lower forced expiratory volume in 1 s (FEV1) identifies a population more likely to ...

In-situ comparison of the NOy instruments flown in MOZAIC and SPURT [PDF]

, 2006
Two aircraft instruments for the measurement of total odd nitrogen (NOy) were compared side by side aboard a Learjet A35 in April 2003 during a campaign of the AFO2000 project SPURT (Spurengastransport in der Tropopausenregion).

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Crystal structures of seven mixed-valence gold compounds of the form [(R1R2R3PE)2AuI]+[AuIIIX4]− (R = tert-butyl or isopropyl, E = S or Se, and X = Cl or Br)

Acta Crystallographica Section E: Crystallographic Communications
During our studies of the oxidation of gold(I) complexes of trialkylphosphane chalcogenides, general formula R1R2R3PEAuX, (R = tert-butyl or isopropyl, E = S or Se, X = Cl or Br) with PhICl2 or elemental bromine, we have isolated a set of seven mixed ...

Current Developments of N-Heterocyclic Carbene Au(I)/Au(III) Complexes toward Cancer Treatment

Biomedicines, 2022
Since their first discovery, N-heterocyclic carbenes have had a significant impact on organometallic chemistry. Due to their nature as strong σ-donor and π-acceptor ligands, they are exceptionally well suited to stabilize Au(I) and Au(III) complexes in ...
