In conclusion, the outdoor fungal profile is diverse even in Seoul, a highly urbanized area in Korea. The distribution of indoor air fungi is significantly different from outdoor due to air quality systems. Heating, ventilation, and air conditioning (HVAC), as well as high-efficiency particulate air (HEPA)-filtered systems should be established to effectively reduce levels of indoor fungi.

Publication date: Available online 13 November 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Duraipandi Devipriya, Selvaraj Mohana RoopanAbstractThe photochemical preparation of benzo[4,5]imidazo[2,1-b]quinazoline was assessed under the illumination of UV wavelength (>360 nm). The compound 3,4-dihydronaphthalen-1(2H)-one 1 with 1H-benzo[d]imidazol-2-amine 2 in the existence of KOH/DMF which lead to the aromatized compound 3. The notable remark of this reaction is that the UV irradiation (312 nm) plays a vital part in the formation of the compound, 3 in shorter duration (2 h) which res...

MaffeiAbstractTo study invasive pulmonary Aspergillosis (IPA), we depleted neutrophils in mice using the monoclonal antibody anti-Gr-1/Ly-6G. Immunocompetent and neutropenic mice were infected via intratracheal with conidia of Aspergillus fumigatus clinical isolates, characterized as either higher or lower elastase producers. Neutropenic animals exhibited 100% mortality in 5 days, for both strains, and were observed survival curves overlapped, lungs with angioinvasion...

Publication date: Available online 13 November 2018Source: Journal of Structural BiologyAuthor(s): Tomohiko Matsuzawa, Masahiro Watanabe, Yusuke Nakamichi, Zui Fujimoto, Katsuro YaoiAbstractIsoprimeverose-producing enzymes (IPases) release isoprimeverose (α-d-xylopyranosyl-(1→6)-d-glucopyranose) from the non-reducing end of xyloglucan oligosaccharides. Aspergillus oryzae IPase (IpeA) is classified as a member of the glycoside hydrolase family 3 (GH3); however, it has unusual substrate specificity compared with other GH3 enzymes. Xylopyranosyl branching at the non-reducing ends of xyloglucan oligosaccharides is v...

Conclusion: Patterns of invasive fungal infections are changing in many ways. In the midst of these evolving trends, IFI of the respiratory tractcontinue to remain important causes of morbidity and mortality. Diagnostic tools can be adequately used only if the treating physician is aware of the propensity of patients to acquire a fungal infection. Thus, continuous awareness and education is crucial for successful management of patients. Judicious use of antifungal medications as prophylactic measures must be employed, particularly in the critically ill and patients of HIV.

We report a case of 12-year-old female with primary hyperoxaluria with regular haemodialysis for the end-stage renal disease. She underwent a combined liver and renal transplantation which got infected by aspergillosis. In this case study, it is speculated that the most likely source of Aspergillus was contaminated preservative solution (perfusate), resulting in infection within the donor kidney and subsequent systemic infection in the recipient. This case study calls for critical analysis and needs for the routine culture of the preservative solution before transplantation, to detect any fungal contamination and manage it prophylactically.

Abstract The chemical characterisation of Pimenta dioica essential oil (PDEO) revealed the presence of 50 components, amongst which α-Terpineol (30.31%) was the major component followed by β-Linalool (6.75%) and γ-Terpinene (4.64%). The oil completely inhibited the growth of aflatoxin B1 secreting strain Aspergillus flavus LHP-VS-8 and aflatoxin B1 production at 2.5 µL/mL and 1.5 µL/mL, respectively. The oil caused dose dependent reduction of methylglyoxal (an AFB1 inducer), enhanced leakage of Ca2+, Mg2+ and K+ ions and significantly reduced ergosterol content of fungal ...
