Veillonella dispar is a Gram-negative anaerobic coccus involved in only a few human diseases. We report the second case of bacteremia due to this microorganism in an elderly patient. A 72-year-old man with a history of bladder cancer presented with diarrhea, vomiting, and fever for 48 hours. After the diagnosis of septic shock, four sets of blood cultures were taken, and three of them yielded V. dispar. Resistance to metronidazole, penicillin, and piperacillin-tazobactam was documented. Treatment with clindamycin was started, and the patient was discharged after improvement in his general condition.

Convincing evidence suggests that non-alcoholic fatty liver disease (NAFLD) is associated with insulin resistance and an increased risk of diabetes; however, the association between lean NAFLD and incident diabetes, and especially differences according to gender, have not been reported thus far. This study therefore aimed to investigate whether lean NAFLD and overweight/obese NAFLD confer the same excess risk of new-onset diabetes in both genders.

Our longitudinal study was performed in 14,482 euglycaemic adults who had participated in a health checkup programme. Fatty liver was diagnosed by abdominal ultrasonography. The outcome of interest was incident diabetes.

Over the median 6.0 years of follow-up, 356 cases of diabetes were diagnosed. After adjusting for sociodemographic and other potential confounders, the fully adjusted HR (95% CI) for incident diabetes in lean NAFLD vs lean without NAFLD patients was 2.58 (95% CI 1.68-3.97) in the total cohort. Corresponding HRs were 5.53 (95% CI 2.30-13.30) and 2.02 (95% CI 1.24-3.31) for women and men, respectively. Post-hoc analysis revealed that the relative risk for developing diabetes was similar between lean and overweight/obese NAFLD groups whether in the entire study population or in subgroups stratified by gender (all P> 0.05).

Lean NAFLD is indeed a risk factor for incident type 2 diabetes in both genders, although the effect appeared to be more pronounced in women than in men. Further investigations are now needed to obtain a better understanding of the natural history of NAFLD in lean subjects.

The process of magnetosome biomineralization requires a precise biological control of redox conditions to maintain a balanced amounts of ferric and ferrous iron. Here, we identified functions of the global regulator OxyR (MGMSRv2_4250, OxyR-4250) in MSR-1 during magnetosome formation. OxyR deletion mutant ΔoxyR-4250 displayed reduced magnetic response, and increased levels of intracellular ROS (reactive oxygen species). OxyR-4250 protein upregulated expression of six antioxidant genes (ahpC1, ahpC2, katE, katG, sodB, trxA), four iron metabolism-related regulator genes (fur, irrA, irrB, irrC), a bacterioferritin gene (bfr), and a DNA protection gene (dps). OxyR-4250 was shown, for the first time, to directly regulate magnetosome island (MAI) genes mamGFDC, mamXY, and feoAB1 operons. Taken together, our findings indicate that OxyR-4250 helps maintain a proper redox environment for magnetosome formation by eliminating excess ROS, regulating iron homeostasis and participating in regulation of Fe2+/Fe3+ ratio within the magnetosome vesicle through regulating MAI genes.In this study, we synthesized and characterized a silicon phthalocyanine substituted with 3-hydroxypyridin-2-thione (SiPc-HDACi), designed to be a chemophotodynamic therapy agent acting as a histone deacetylase inhibitor, and we determined its photophysical, photochemical, and photobiological properties. Next, we evaluated its anticancer efficacy on MCF-7, double positive and MDA-MB-231, triple negative breast cancer cell lines, as well as on a healthy human endothelial cell line (HUVEC). Our results indicate that SiPc-HDACi can target nucleoli of cells, effectively inducing apoptosis while promoting cell cycle arrest thanks to its high singlet oxygen yield and its histone deacetylase downregulating properties, suggesting a powerful anticancer effect on breast cancer in vitro. Our further studies will be conducted with primary breast cancer cell culture to give a better insight into the anticancer mechanism of the compound.Massive attention has been paid to MXenes due to their intriguing properties and potential diverse applications. Extensive studies using first-principles calculations on the electronic structures of MXenes Cr2CO2 and Cr2NO2 were performed in this paper. Based on the accurate Heyd-Scuseria-Ernzerhof (HSE) calculations, Cr2CO2 is clarified to be a ferromagnetic semiconductor; meanwhile, Cr2NO2 is a half-metallic material, which is consistent with previous results. In particular, by analyzing the contribution of the orbitals to the band structures and density of states, the basic mechanism of ferromagnetism was analyzed in detail. Our theoretical work might promote the spintronics study and application of Cr-contained MXenes.G0S2 is a small protein of 103 residues in length that is involved in multiple cellular processes. To date, several reports have shown that G0S2 functions by making direct protein-protein interactions with key proteins. Pyrintegrin in vitro In lipolysis, G0S2 specifically interacts with adipose triglyceride lipase, inhibiting its activity and resulting in lipolysis being downregulated. In a similar way, G0S2 also participates in the regulation of apoptosis, cell proliferation, and oxidative phosphorylation; however, information regarding G0S2 structural and biophysical properties is limited. In this work, we conducted a comparative structural analysis of human and mouse G0S2 proteins. Bioinformatics suggests the presence of a disordered C-terminal region in human G0S2. Experimental characterization by size-exclusion chromatography and dynamic light scattering showed that human and mouse G0S2 have different hydrodynamic properties. In comparison to the mouse G0S2, which behaves similar to a globular protein, the human G0S2 shows an elongated conformation, most likely by displaying a disordered C-terminal region.
