Older patients, those with cT1 disease and hydronephrosis were more likely to upstage.The uridine-rich 7 (U7) small nuclear RNA (snRNA) is a component of a small nuclear ribonucleoprotein complex (snRNP). Naturally, the U7 snRNA contains an antisense sequence that identifies histone pre-mRNAs and is involved in their 3'-end processing. By altering this antisense sequence, researchers have modified U7 snRNA to become a versatile tool for targeting mRNAs and for modifying splicing. Encapsulating a modified U7 snRNA into a viral vector such as adeno-associated virus (also referred as vectorized exon skipping/inclusion, or VES/VEI) enables the delivery of this highly efficacious splicing modulator into a range of cell lines, primary cells, and tissues. Additionally, and in contrast to antisense oligonucleotides, viral delivery of U7 snRNA enables long-term expression of antisense sequences in the nucleus as part of a stable snRNP complex. As a result, VES/VEI has emerged as a promising therapeutic platform for treating a large variety of human diseases caused by errors in pre-mRNA splicing or its regulation. This review will provide an overview over U7 snRNAs natural role and its applications in gene therapy.Aim Orally taken pirfenidone (PFD) often causes digestive symptoms. A respirable powder formulation of PFD (PFD-RP) was previously developed, and this study aimed to verify the risk of digestive symptoms after insufflation of PFD-RP. Materials & methods Intestinal motility and gastrointestinal exposure levels was evaluated in PFD-RP (0.3-mg PFD/rat a pharmacologically effective dose) and orally taken PFD (10-100 mg/kg) groups. Results & conclusion Orally taken PFD at doses above 30 mg/kg significantly inhibited intestinal motility. In contrast, insufflated PFD-RP led to comparable intestinal motility in control group, and gastrointestinal exposure levels in PFD-RP group we
