Stem Cells International, 2012 Culturing stem cells for an extended period of time can lead to acquired chromosomal aberrations. Determining the copy number variant (CNV) profile of stem cell lines is critical since CNVs can have dramatic effects on gene expression and tumorigenic ...

Increasing X‐ray energy improves data quality in serial crystallography
Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 344-350, March 2026.Advanced serial crystallography utilizing high‐energy X‐rays enhances diffraction efficiency, data quality and structural resolution under room‐temperature conditions.Serial synchrotron crystallography (SSX) enables structure determination from microcrystals under near‐physiological, room‐temperature conditions but is limited in part due to the ...

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective
The FEBS Journal, Volume 293, Issue 6, Page 1801-1817, March 2026.Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...

Human FASTK preferentially binds single‐stranded and G‐rich RNA
The FEBS Journal, Volume 293, Issue 3, Page 729-748, February 2026.Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.Complex salts with potassium counter cations and bisdithiolene oxido molybdate or tungstate anions are water tolerant and soluble in purely aqueous medium. Four different synthetic routes to water‐soluble complexes of the type K2[MOx(dt)2] (M = Mo, W; dt = ene‐1,2‐dithiolate, x = 1, 2) applicable to different ligand precursors are presented.

A national estimate of U.S. underground natural gas storage incident emissions
Environmental Research Letters, 2022 The 2015 Aliso Canyon storage well blowout was widely reported as the worst natural gas leak in the history of the United States (U.S.) and released ∼0.1 million metric tons of methane (CH _4 ), a potent greenhouse gas.

The FEBS Journal, Volume 293, Issue 1, Page 257-270, January 2026.Soluble cargo proteins are sorted to the vacuoles via a receptor‐mediated mechanism. Combining crystallographic and mutagenesis studies, we showed how the C‐terminal sorting determinant (ctVSD) of vicilin‐like seed storage protein VL22 is recognized by the protease‐associated domain of Arabidopsis vacuolar‐sorting receptor 1.

Los tubérculos radiculares del aliso (?"Alnus jorullensis"? H. B. K. var. "?Spachii"? Regel)
Lilloa, 1944 El autor, con el fin de ubicar la especie, transcribe la descripción original del subgénero Gymnothyrsus, ilustrándolo con dibujos de la inflorescencia y las flores. También describe e ilustró los tubérculos radicales de esta especie.
