This p.p.r concerns a certain subcategory of the category of rep.esentations for a semisimp.e algebraic group.G in characteristic p. which arises from the semisimp.e modules for the corresp.nding quantum group.at a p.th root of unity. The subcategory, thus, records the cohomological difference between quantum group. and algebraic group.. We define translation functors in this category and use them to obtain information on the irreducible characters for G when the Lusztig character formula does not hold.

The heterotop.c p.ncreas, which is usually described as an untyp.cal p.esence of p.ncreatic tissue without any anatomic or vascular continuity with the p.ncreas, is relatively rare. Clinical manifestations may include bleeding, inflammation, p.in and obstruction; however, in most cases it remains silent and is diagnosed during autop.y. Here, we rep.rt a case of ectop.c p.ncreatic lesion located in the gastric cardia. The p.tient was a 73-year-old woman who had a history (over four months) of chronic ep.gastric p.in accomp.nied by heartburn. Esop.agogastroduodenoscop. revealed inflammatory changes throughout the stomach and lower esop.agus, as well as a flat p.lyp.id mass with benign features located in the gastric cardia, ap.rox. 10 mm below the “Z” line, measuring ap.rox. 7 mm in diameter. Endoscop.c biop.y forcep. were used to remove the lesion. Histological examination of the lesion revealed the p.esence of heterotop.c p.ncreatic tissue in the gastric mucosa. On the basis of the p.esented case, we suggest that p.ncreatic ectop.a should be a p.rt of differential diagnosis, not only when dealing with submucosal gastric lesions, but also with those that are small, flat and/or untyp.cally located.

This work was made to investigate how nucleation and growth behavior of the coating film were affected by surface top.grap.ies of Mg–Al–Zn alloy substrate during the initial stage of p.asma electrolytic oxidation(p.O).To satisfy this end,a single substrate was p.ep.red by mechanical treatment exhibiting rough and smooth regions with an equal area on the *** rough region with p.ominent hills and grooves induced the breakdown of p.ssive film,which was indicated by an early ap.earance of p.asma discharge on the rough region since nucleation of coating film occurred p.eferentially around the ***,the coating film grown on the grooves was somewhat thicker and more p.rous than the film grown on the hills and smooth *** was due to the fact that the growth of the coating film was found to be localized in the p.esence of rough region,which was in line with the discharge ***,the nucleation and growth behavior during the initial stage of p.O will be discussed schematically on the basis of microstructural interp.etation.

The exp.oration and identification of antip.oliferative p.ytochemicals have received increased attention in medicinal chemistry. In p.rticular, research focused on the toxicology of marine natural p.oducts has increased in recent years. Terp.noids, among many secondary metabolites, have been demonstrated to act as effective anticancer agents. Soft corals, a group.of marine invertebrates, p.oduce a variety of terp.noids with biofunctional p.op.rties. The current study p.esents the extraction, p.rification, and identification of sterol congeners from the soft coral Dendronep.thya p.tteri. The method involves 50% chloroform-methanol extraction, p.lar column fractionation, and analysis through GC-MSn. Dose-dep.ndent antip.oliferative activity was observed within the sterol-rich fraction (Dp.MH 2-4), which consisted of 3β-hydroxy-Δ5-steroidal congeners. This fraction inhibited the growth of HL-60 and MCF-7 cells with IC50 values of 25.27±1.43 and 22.81±0.15 μg/mL, resp.ctively. Ap.p.otic body formation, DNA damage, cell cycle arrest, and ap.p.otic cell signaling p.thway activation were also observed, reinforcing the dose-dep.ndent antip.oliferative and ap.p.osis-inducing activity of 3β-hydroxy-Δ5-steroidal congeners. To our knowledge, this is the first rep.rt of anticancer agent identification from the soft coral D. p.tteri. Based on the observations, these steroidal congeners are p.omising candidates for the develop.ent of anticancer drugs.
