21-cm H I emission from the Damped Lyman- [PDF]
, 2001 We detect 21-cm emission from the Low Surface Brightness (LSB) galaxy SBS 1543+593, which gives rise to a Damped-Lyα (DLyα) absorption line in the spectrum of the background QSO HS 1543+5921 ($z_{\rm e} = 0.807$).

Irregular changes in H α emission line of V423 Aur observed by LAMOST Medium-Resolution Spectrographs [PDF]
Research in Astronomy and Astrophysics, 2020 Abstract We obtained seven spectra of the Be star V423 Aur on 2017 Dec. 5 using the LAMOST Medium-Resolution Spectrograph with exposures from 600 to 1200 seconds. These spectra show the irregular H α emission line profile variations (LPVs). In the seven spectra, from the 4th

Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy
FEBS Letters, EarlyView.The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.

Two extremely metal-poor emission-line galaxies in the Sloan Digital Sky Survey
, 2006 We present spectroscopic observations with the 3.6 m ESO telescope of two emission-line galaxies, J2104-0035 and J0113+0052, selected from the Data Release 4 (DR4) of the Sloan Digital Sky Survey (SDSS).

Inner Warm Disk of ESO Hα 279a Revealed by NA i and CO Overtone Emission Lines [PDF]
The Astrophysical Journal, 2017 Abstract We present an analysis of near-infrared, high-resolution spectroscopy toward the flat-spectrum young stellar object (YSO) ESO Hα 279a (∼1.5M ⊙) in the Serpens star-forming region at a distance of 429 pc. Using the Immersion GRating INfrared Spectrometer (IGRINS; R ≈ 45,000), we detect emission lines originating

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

$\text{H}\alpha$ dots: A catalog of faint emission-line objects discovered in narrowband images [PDF]
, 2012 During a wide-field narrowband $\text{H}\alpha$ imaging survey, we noted the presence of numerous isolated emission-line point sources in the data. These objects could represent ultra-low-luminosity galaxies at low-redshift (detection via $\text{H}\alpha$
