Coal preparation by-products, such as coal gangue, are inferior fuels enriched with trace elements (TEs). Owing to the issues surrounding the disposal of coal preparation by-products and energy shortages, Chinese researchers have strongly advocated harvesting energy from by-products. However, the secondary environmental pollution caused by such by-products has been overlooked. In this study, we aimed to assess the contamination of soil and maize (Zea mays L.) near a coal gangue-fired power plant (CGPP) in Liupanshui City, Guizhou Province, China, by TEs. The contents of 11 TEs (Be, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sb, V, and Zn) in soil samples and different maize tissues were measured, and their chemical speciation in soil was also determined. The results showed that the soil in the study area was polluted by the above elements to varying degrees at a very high potential ecological risk. The Cr and Pb levels in niblets of partial samples exceeded the Chinese food safety standards. The TE contents of maize tissues largely depend on the bioavailable fraction of the same elements in the soils, rather than their total contents. Pearson's correlation and hierarchical cluster analyses resulted in three clusters(1) Pb-Zn-Cd; (2) Co-Cu-Mn-Sb-V-Be; and (3) Cr-Ni. Coal preparation by-products should not be directly combusted without pre-treatment. These results will aid readers and engineers in understanding the adverse effect of CGPPs and provide regulators and policymakers with relevant data to scientifically guide the utilisation of coal preparation by-products.
Candida albicans is the most frequent pathogenic fungus in oral cavities. It adheres to dental tissues as part of dental plaques and contributes to caries formation.

To evaluate the effect of silver diamine fluoride (SDF) on reducing C. albicans adhesion on dentine surfaces.

Flat dentine surfaces were prepared from bovine dental disks, and samples were divided into three groups. The first and second groups were pretreated for 3min with 299mM or 2.99M SDF, respectively, and the third group (control) did not undergo any SDF pretreatment. All samples were washed, inoculated with C. albicans suspension onto their dentine surface, incubated at 30°C for 6h, and washed again to remove any nonadherent cells. The abundance of adherent cells was investigated using colorimetric and real-time polymerase chain reaction approaches. Subsequently, the morphological changes in C. albicans by pretreatment with SDF were observed under a scanning electron microscope (SEM).

SDF inhibited candidal growth at concentrations as low as 2.99µM. Dentine disks pretreated with 299mM or 2.99M SDF displayed significantly fewer adhered cells as compared with the control group. Upon pretreatment with SDF, SEM images showed severe morphological changes in the cellular walls, in a dose-dependent manner, suggesting a fungicidal effect of SDF against the yeast.

SDF should be considered for clinical applications aimed at inhibiting dental plaque caused by C. albicans, particularly in children and elderly individuals.

As the generic name Emmonsia is no longer available for this species, its taxonomic position is re-evaluated. The intraspecific variation of Emmonsia crescens was analyzed using molecular, morphological, and physiological data, and the relationship between frequency of adiaspiromycosis and body temperature of host animals was explored. A North American and a pan-global lineage could be discerned, each with subclusters at low genetic distance. European strains produced the classical type of very large adiaspores, while in the North American lineage adiaspores relatively small, resembling the broad-based budding cells of Blastomyces. SN-38 molecular weight Members of the closely related genus Emergomyces may exhibit large, broad-based in addition to small, narrow-based budding cells. We conclude that the morphology of the pathogenic phase in these fungi differs gradationally between species and even populations, and is therefore less suitable as a diagnostic criterion for generic delimitation. Two Emmonsia species are reclassified in Emergomyces.
In this study, we evaluate the efficacy and safety of the biosimilar infliximab, CT-P13, in the treatment of inpatients with severe steroid-refractory colitis.

A retrospective cohort study of adult colitis patients (UC or isolated Crohn's colitis) admitted to the University of Chicago inflammatory bowel disease inpatient service between January 2018 and December 2018 for management of severe colitis refractory to IV steroids who received CT-P13 were included in the study. Patients diagnosed with active small bowel Crohn's disease were excluded. CT-P13 was given as a single infusion of 5 to 10 mg/kg. A comprehensive review of their electronic medical records was performed, and demographic, clinical, laboratory, and endoscopic data were extracted. The primary endpoint was colectomy-free survival.

Twenty-one patients with severe steroid-resistant colitis were included. Twelve patients had ulcerative colitis, seven patients had a diagnosis of indeterminate colitis, and two patients had a diagnosis of Crohn's colitis. The median age was 32.2 years. The median disease duration was 4.3 years, and the median follow-up time was 5.9 months. Patients had a median CRP of 23. All patients had moderate to severe disease on endoscopy. Colectomy-free survival was 76% at 3 months and 70% at 6 months. No severe adverse events were reported in this patient cohort.

A significant proportion of patients with severe colitis failing IV steroids responded to induction therapy with CT-P13. Colectomy-free survival rates were similar to previous randomized trials using originator infliximab as induction therapy in severe steroid-refractory colitis.
