The effect of pressure on the crystal structure of hexagonal L-cystine [PDF]

, 2005
The crystal structure of hexagonal L-cystine has been determined at room temperature at pressures between 0.4 and 3.7 GPa; unit-cell dimensions were measured up to 6.4 GPa. The structure of this phase consists of molecules in their zwitterionic form, and

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Crystal structures of the three closely related compounds: bis[(1H-tetrazol-5-yl)methyl]nitramide, triaminoguanidinium 5-({[(1H-tetrazol-5-yl)methyl](nitro)amino}methyl)tetrazol-1-ide, and diammonium bis[(tetrazol-1-id-5-yl)methyl]nitramide monohydrate

Acta Crystallographica Section E: Crystallographic Communications, 2017
In the molecule of neutral bis[(1H-tetrazol-5-yl)methyl]nitramide, (I), C4H6N10O2, there are two intramolecular N—H...O hydrogen bonds. In the crystal, N—H...N hydrogen bonds link molecules, forming a two-dimensional network parallel to (-201) and weak C—

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

FEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Ethyl 3-methyl-1-oxo-4H-1,4-benzothiazine-2-carboxylate monohydrate

IUCrData, 2018
The organic molecule in the title hydrate, C12H13NO3S·H2O, is folded across the S...N vector. Chains two molecules thick extending along the a-axis direction are formed by N—H...O and O—H...O hydrogen bonds.

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

FEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Crystal structure of N-(quinolin-6-yl)hydroxylamine

Acta Crystallographica Section E, 2014
The title compound, C9H8N2O, crystallized with four independent molecules in the asymmetric unit. The four molecules are linked via one O—H...N and two N—H...N hydrogen bonds, forming a tetramer-like unit.

Intramolecular N-H...O, intermolecular O-H...O, C-H...O and Csp³-H...πarene interactions in (2S)-2-{[(2R)-2-hydroxy-2-phenylethanoyl]amino}-4-methylpentanoic acid [PDF]

, 1999
The title compound, C₁₄H₁₉NO₄, forms a hydrogenbonded network in the solid state, consisting of one intramolecular N--H...O [N...O 2.569 (3)Å] and two intermolecular O--H...0=C [O...O 2.704(2) and 2.801 (2)Å] hydrogen bonds, with weaker C--H...O [C...O ...
