Observation of a bacteriochlorophyll anion radical during the primary charge separation in a reaction center [PDF]

, 1989
The primary light-induced charge separation in reaction centers of Rhodobacter sphaeroides was investigated with femtosecond time resolution. The absorption changes in the time range 100 fs to 1 ns observed after direct excitation of the primary donor P ...

The effect of military load carriage on ground reaction forces [PDF]

, 2007
Load carriage is an inevitable part of military life both during training and operations. Loads carried are frequently as high as 60% bodyweight, and this increases injury risk. In the military, load is carried in a backpack (also referred to as a Bergen)

Cardiolipin increases in chromatophores isolated from Rhodobacter sphaeroides after osmotic stress: structural and functional roles

Journal of Lipid Research, 2009
Chromatophores isolated from cells of Rhodobacter sphaeroides exposed to hypertonic solutions were enriched in cardiolipin (CL). Because CL levels are raised by increasing the incubation time of R.

Beyond Native Reaction Centers [PDF]

, 1990
The past five years after solving the crystal structure of the bacterial reaction center from Rhodopseudomonas (Rp.) viridis [1] — and the first Feldafing meeting [2] — have witnessed a remarkable concentration of interdisciplinary research on this pigment-protein complex.

Elucidation of Pd modification effect on catalytic behaviors of γ-Al2O3-P catalysts toward ethanol dehydration and dehydrogenation

Catalysis Communications, 2021
The catalytic ethanol dehydration and dehydrogenation over γ-Al2O3-P catalysts with Pd modification were investigated. The Al2O3-P is promising to obtain the highest yield of diethyl ether (ca.

Ultrafast structural dynamics of carbon–carbon single-bond rotation in transient radical species at non-equilibrium

Nature Communications
Bond rotation is an important phenomenon governing the fate of reactions. In particular, heterogeneously substituted ethane derivatives provide distinct structural conformations around the bond, empowering them as ideal systems for studying the rotation ...

Deep Sequencing of FLT3‐ITD Enables Response Evaluation and Post‐Treatment Monitoring in Childhood AML: An Exploratory Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...
