Leiomyoma with bizarre nuclei (LBN) have significant cytologic atypia, but high mitotic rate and tumor cell necrosis are absent. Although it is a benign leiomyoma variant, recurrent cases have been described. In this study, we investigated the clinical and pathologic features of LBN and compared them with related studies. A total of 30 patients diagnosed with LBN in our department were included in this study. In all cases, clinical data (age, complaint, surgery type), macroscopic features (size, location, number of leiomyomas, necrosis, and hemorrhage), microscopic features (bizarre cell distribution, bizarre cell density, cellularity, mitotic rate, tumor margin, necrosis, nuclear pseudoinclusions, karyorrhectic nuclei, prominent eosinophilic nucleoli with perinucleolar clearing, cytoplasmic eosinophilic inclusions, staghorn vessels, and alveolar-type edema), and follow-up data (recurrence and survival period) were evaluated...

The relationship between skeletal muscle volume and the prognosis of patients with inflammatory bowel disease (IBD) remains undetermined. We conducted a retrospective study of 72 IBD patients who were admitted to the hospital due to disease exacerbation. We enrolled IBD patients who had undergone abdominal computed tomography and assessed the nutritional indices, such as the Onodera's prognostic nutritional index (O-PNI) and the controlling nutritional status (CONUT) index. The L3 skeletal muscle index (SMI), which is the ratio of the cross-sectional area of skeletal muscles at the level of the third lumbar (L3) vertebra to the height squared, was used to identify sarcopenia...

When the sensory block level (SBL) is ≥T5 or T4, a high incidence of hypotension occurs in parturients after spinal anesthesia. A rapidly ascending SBL is another risk factor for spinal anesthesia-induced hypotension. However, the relationship between the ascension rate of the SBL and spinal anesthesia-induced hypotension remains unclear.After placement in the left lateral position, combined epidural-spinal anesthesia was performed on 140 parturients undergoing caesarean section using the following procedure: no volume preloading, injection site of L3-4 or L4-5, injection rate of 0...

Several groups of antibiotics inhibit bacterial growth by binding to bacterial ribosomes. Mutations in the ribosomal protein L3 have been associated with resistance to linezolid and tiamulin, which both bind at the peptidyl transferase center in the ribosome. Resistance to these and other antibiotics also occurs through methylation of 23S ribosomal RNA at position A2503 by the methyltransferase Cfr. The mutations in L3 and the cfr gene have been found together in clinical isolates, raising the question whether they provide a combined effect on antibiotic resistance or growth...

The exceptional thermal and chemical stability of the UiO-66, -67 and -68 classes of isostructural MOFs [J. Am. Chem. Soc., 2008, 130, 13850] makes them ideal materials for functionalization purposes aimed at introducing active centres for potential application in heterogeneous catalysis. We previously demonstrated that a small fraction (up to 10%) of the linkers in the UiO-67 MOF can be replaced by bipyridine-dicarboxylate (bpydc) moieties exhibiting metal-chelating ability and enabling the grafting of Pt(ii) and Pt(iv) ions in the MOF framework [Chem...
