For cases with a low proportion of abnormal cells, cytologically targeted microdissection of cells for NGS should maintain sensitivity and decrease sequencing costs. Cytologically targeted urothelial cells for NGS could allow a screening test for low grade UC.
Cytology is immediately poised to allow NGS to improve the diagnosis of UC, allowing NGS to be an ancillary test for atypical cytologies, and potentially allowing a screening test for low-grade UC.

This study evaluated the radiopacity of 2 bulk-fill resins (SonicFill and Filtek Bulk Fill) and a nanocomposite (Filtek Z350 XT) resin compared with enamel, dentin, and aluminum as measured with different exposure parameters.
Resin disks were radiographed together with a 1-mm human tooth section and an aluminum stepwedge, at exposure times of 0.2 and 0.32 s, and source-image (S-I) distances of 30 and 40 cm, using complementary metal oxide semiconductor (CMOS) and photostimulable phosphor systems. Grayscale values were measured using ImageJ software. Paired Student t tests were used to compare the effect of the receptor on grayscale values for each material. Analysis of variance was used to evaluate the effects of receptor, exposure parameters, and the resins on radiopacity.
All resins exhibited greater radiopacity scores than enamel and were significantly different from each other. Filtek Z350 produced the lowest radiopacity values, whereas SonicFill produced the highest. The radiopacity values were higher on images acquired with CMOS receptors. Receptor type, exposure time, S-I distance, and material, as well as many interactions of these parameters, affected the radiopacity of the resins.
The tested resins complied with ISO 4049. Exposure parameters and digital receptors affected their radiopacity.

Here, we report a 74-year-old woman undergoing chemotherapy for recurrent renal cell carcinoma, who presented with abdominal pain after administration of pazopanib following nivolumab and was diagnosed with severe acute pancreatitis. Administration of methylprednisolone and conservative treatment were initiated, but clinical findings and laboratory tests rapidly worsened. When she died, an autopsy was performed. The autopsy findings suggested the possibility of pancreatitis as immune-related adverse events. To the best of our knowledge, no fatal cases of acute pancreatitis due to nivolumab or pazopanib have been reported. We considered that the effects of nivolumab were sustained in the pancreas, and pazopanib administration might have worsened the toxicity.Opioids are well known for their potent analgesic efficacy and severe side effects. Studies have shown that analgesic effects are mediated by the downstream G-protein-dependent pathway of the μ-opioid receptor (MOR), and another β-arrestin-dependent pathway mediates side effects such as respiratory depression, constipation and tolerance etc. TRV130 is a biased ligand for G-protein-dependent pathway, which has high analgesia and has fewer side effects than morphine. In this study, the structure similarity search was performed on the IBSSC database using Oliceridine (TRV130) and PZM21 as templates. The 3D structure-based pharmacophore model was built and combined molecular docking prediction mode was selected to filter out small molecules, Finally, based on affinity prediction, four candidate molecules were obtained. Molecular dynamics simulations explored the detailed interaction mechanism of proteins with small molecules under dynamics. These results suggest that these candidate molecules are potential MOR agonists.Osteoclasts are bone resorption cells of myeloid origin. Osteoclast defects can lead to osteopetrosis, a genetic disorder characterized by bone sclerosis for which there is no effective drug treatment. It is known that Pu.1 and Fms are key regulators in myelopoiesis, and their defects in mice can lead to reduced osteoclast numbers and consequent osteopetrosis. Yet how Pu.1 and Fms genetically interact in the development of osteoclasts and the pathogenesis of osteopetrosis is still unclear. Here, we characterized pu.1G242D;fmsj4e1 double-deficient zebrafish, which exhibited a greater deficiency of functional osteoclasts and displayed more severe osteopetrotic symptoms than the pu.1G242D or fmsj4e1 single mutants, suggesting a synergistic function of Pu.1 and Fms in the regulation of osteoclast development. We further demonstrated that Pu.1 plays a dominant role in osteoclastogenesis, whereas Fms plays a dominant role in osteoclast maturation. TI17 cell line Importantly, treatment with the drug retinoic acid significantly relieved the different degrees of osteopetrosis symptoms in these models by increasing the number of functional osteoclasts. Thus, we report the development of valuable animal models of osteopetrosis, and our results shed light on drug development for antiosteopetrosis therapy.One of the main causes of pregnancy failure and fetus abortion is oocyte aneuploidy, which is increased with maternal aging. Numerous possible causes of oocyte aneuploidy in aged women have been proposed, including cross-over formation defect, cohesin loss, spindle deformation, spindle assembly checkpoint malfunction, microtubule-kinetochore attachment failure, kinetochore mis-orientation, mitochondria dysfunction-induced increases in reactive oxygen species, protein over-acetylation, and DNA damage. However, it still needs to be answered if these aneuploidization factors have inherent relations, and how to prevent chromosome aneuploidy in aged oocytes. Epidemiologically, oocyte aneuploidy has been found to be weakly associated with higher homocysteine concentrations, obesity, ionizing radiation and even seasonality. In this review, we summarize the research progress and present an integrated view of oocyte aneuploidization.
