Abstract
Lay Summary
We present a case series of 16 patients with ulcerative colitis who received upadacitinib after failing tofacitinib. Five patients (36%) achieved steroid-free clinical remission. Five (62%) demonstrated endoscopic response, while 2 patients (25%) achieved endoscopic remission. Adverse events were low.

Abstract
Human colon carcinoma cells were analyzed for lipid phosphorus, cholesterol and glycosphingolipids. Ceramide mono-, di- and trihexosides and sulfatides were isolated by column and thin-layer chromatography and determined quantitatively on the basis of their hexose content. The complex lipid fractions so isolated were only partially resolved with the material available. Gangliosides GM2 and GM3 and globoside were major components of the fraction and were determined on the basis of their hexose, hexosamine and neuraminic acid content. The HCT 116, 116a and 116b cells contained no fucolipids. Cell lines resistant to mitomycin C, teniposide and etoposide were developed and analyzed. Over the 5 year period of the study sulfatides declined to about one-fourth of their original amounts in both parent and drug-adapted cells. HCT 116 cells adapted to mitomycin C and teniposide had 30% less ceramide monohexoside and a 45% greater cholesterol to lipid phosphorus ratio than the parent cells. Reductions in ceramide dihexoside in the drug-adapted cells were greater than those of the ceramide monohexoside. Galabiosyl ceramide was the major ceramide dihexoside in all the cells and accumulated in HCT 116a to levels 4-6-fold greater than that of the other lines as the only dihexoside.

Abstract
A precursor of 5S ribosomal ribonucleic acid (rRNA) from Bacillus subtilis was cleaved by ribonuclease (RNase) M5 in cell-free extracts from B. subtilis to yield the mature 5S rRNA plus RNA fragments derived from both termini of the precursor. The released, mature 5S rRNA was stable in these extracts; however, as occurred in vivo, the precursor-specific fragments were rapidly and completely destroyed. Such destruction was not observed in the presence of partially purified RNase M5, so fragment scavenging was not effected by the maturation nuclease itself. The selective destruction of the precursor-specific fragments was shown to occur through a 3'-exonucleolytic process with the release of nucleoside 5'-monophosphates; the responsible activity therefore had the character of RNAse II. Consideration of the primary and probable secondary structures of the precursor-specific fragments and mature 5S rRNA suggested that involvement of 3' termini in tight secondary structure may confer protection against the scavenging activity.
