Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Stellar masses of SDSS-III BOSS galaxies at z~0.5 and constraints to galaxy formation models [PDF]

, 2013
We calculate stellar masses for ∼400 000 massive luminous galaxies at redshift ∼0.2–0.7 using the first two years of data from the Baryon Oscillation Spectroscopic Survey (BOSS).

Photometric Classification of Single and Binary Stars with Mock CSST Observations

The Astronomical Journal
Identifying unresolved binary stars from broadband photometry is important for studies of stellar evolution, binary populations, and Galactic structure, but remains challenging because many single and binary systems occupy overlapping regions of ...

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Spectroscopy and spectral types for 387 stellar objects from the large, bright QSO survey

The Astrophysical Journal Supplement Series, 1992
Spectroscopy and spectral types for 387 stellar objects brighter than B J = 18.75 found in the Large, Bright QSO Survey (LBQS) are reported. The spectra were observed with the MMT at moderate resolution (6 A FWHM) and low S/N, and cover the interval λλ3200-7400.
