Insight into the response of anammox granule rheological intensity and size evolution to decreasing temperature and influent substrate concentration.

Anammox granules are advantageous because of their relatively higher nitrogen removal rate (NRR) and biomass retention capacity in ammonia-containing wastewater treatment. However, little attention has been paid to granule rheological intensity and size evolution, especially under low temperature and substrate concentration conditions. In this study, the size evolution and variations in rheological properties associated with biochemical characteristics of anammox granules were investigated at decreasing temperatures (35 → 13 °C) and influent substrate concentrations (300 → 50 mg NH-N L).

Comparison of enhancement of anaerobic digestion of waste activated sludge through adding nano-zero valent iron and zero valent iron.

The feasibility of adding nano-zero valent iron (NZVI: 0.6, 1.0, 4.

Recalcitrant primary subcutaneous phaeohyphomycosis due to Phialophora verrucosa.

Phialophora verrucosa has rarely been reported for causing phaeohyphomycosis, which tends to occur in immunocompromised individuals. The case of primary subcutaneous phaeohyphomycosis due to P. verrucosa in an otherwise healthy Chinese female is presented.

The effects of temperature, pH, and salinity on the growth and dimorphism of Penicillium marneffei.

Penicillium marneffei is an important thermal dimorphic fungus that is endemic to Southeast Asia and China and causes penicilliosis, an AIDS-defining disease. Dimorphic switching is considered an important growth characteristic associated with its pathogenicity. In recent years, the molecular mechanisms underlying both dimorphic switching and monomorphic growth have been studied.

[Population studies of Exophiala jeanselmeis by sequence analysis in the ribosomal DNA].

Objective: To study the populations of Exophiala jeanselmei strains from diverse sources using rDNA sequences.

Methods: Tested strains included 20 isolates of Exophiala jeanselmei (type culture, reference culture, clinical and environmental isolates), 8 isolates of E. moniliae, 1 isolate of Exophiala werneckii, respectively.

[Application of molecular biology techniques in the identification of pathogenic fungi and the diagnosis of fungal infection].

With the increasing incidence and mortality of fungal infection, the requirements for strict diagnostic approaches became a very urgent issue. Because of the traditional detective techniques, such as culture, gave poor diagnostic outcomes, the molecular biological techniques are expected to develop the potential diagnostic approaches. During the past decades, we have carried out serial studies on the molecular properties of pathogenic fungi, and we would like to review as following.

[Differentially expressed genes in immunosuppressive and healthy mice after intranasal inoculation of Aspergillus fumigatus].

Objective: To screen out the differential expression genes between the immune suppressive host and healthy host after intranasal inoculation of Aspergillus fumigatus (A fumigatus).

Methods: Six immune suppressive mice and 6 healthy mice were inoculated with A, fumigatus intranasally. Three days after the inoculation the mice were killed and autopsied.

[Pemphigus patient with pulmonary fungal infection caused by Ochroconis gallopava: the first case report in China].

Objective: To report a case of pemphigus complicated by pulmonary infection due to Ochroconis gallopava, the first such case in China.

Methods: A male pemphigus patient with pulmonary symptoms, aged 68, received a needle biopsy under CT scan. The materials obtained from the lung cavity were cultured on Sabouraud dextrose agar in four test tubes.

Cloning of Aspergillus fumigatus histidine kinase gene fragment and its expression during invasive infection.

It was demonstrated recently that three histidine kinases genes in Candida albicans contributed to virulence, indicating the importance of signaling pathways regulated by histidine kinases. In the present study, using a set of degenerate primers, RT-PCR was performed with cDNA of A. fumigatus as a template.
