Psoriasis is a T cell mediated chronic inflammatory skin disease affecting about 2% of the population worldwide. Recently has established the central role of IL-23/Th17 immune axis in the pathogenesis of psoriasis and different subclasses of T cells including Th1 and Th17 cells are involved in initiation and amplification of the skin inflammation process, in addition, in cases of recurrent psoriasis, Th22 cells play the role of memory cells with the help of Th9 cells, which are also important in this process. The main goal was to evaluate the ratio of T cell profile and IL23/Th17 axis by evaluating IL17A, IL22, IL9 in peripheral blood of persons with moderate to severe plaque psoriasis. Read More

Impact of CO overpressure on yeast mitochondrial associated proteome during the "prise de mousse" of sparkling wine production.

Int J Food Microbiol 2021 May 4;348:109226. Epub 2021 May 4.

Department of Agricultural Chemistry, Edaphology and Microbiology, Severo Ochoa (C6) building, Agrifood Campus of International Excellence CeiA3, University of Cordoba, Ctra. N-IV-A mm 396, 14014 Cordoba, Spain. Electronic address:

The "prise de mousse" stage during sparkling wine elaboration by the traditional method (Champenoise) involves a second fermentation in a sealed bottle followed by a prolonged aging period, known to contribute significantly to the unique organoleptic properties of these wines. During this stage, CO overpressure, nutrient starvation and high ethanol concentrations are stress factors that affect yeast cells viability and metabolism. Since mitochondria are responsible for energy generation and are required for cell aging and response to numerous stresses, we hypothesized that these organelles may play an essential role during the prise de mousse.

Outcomes of hematopoietic cell transplantation (HCT) in patients with mixed response to treatment of confirmed or suspected invasive fungal infection before HCT.

Transplant Cell Ther 2021 May 5. Epub 2021 May 5.

Department of Medicine, University of Washington, Seattle, WA; Vaccine and Infectious Disease Division, Fred Hutchinson Cancer Research Center, Seattle, WA; Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA.

Background: Patients with hematologic malignancy or bone marrow failure are typically required to achieve radiographic improvement or stabilization of invasive fungal infection (IFI) prior to hematopoietic cell transplant (HCT) due to concern for progression prior to engraftment. Refractory IFI with a mixture of improvement and progression on serial imaging (or a "mixed response") poses a clinical dilemma, as delay in HCT may allow hematologic relapse or other complications. Further, HCT itself may yield the immune reconstitution necessary for clearance of infection. Read More

p-Coumaric acid loaded into liquid crystalline systems as a novel strategy to the treatment of vulvovaginal candidiasis.

Int J Pharm 2021 May 5:120658. Epub 2021 May 5.

Department of Drugs and Medicines, School of Pharmaceutical Sciences, São Paulo State University (UNESP), Araraquara, São Paulo, Brazil.

Vulvovaginal candidiasis (VVC) is an extremely common type of vaginal infection, which is mainly caused by Candida albicans. However, non-albicans Candida species are frequently more resistant to conventional antifungal agents and can represent up to 30% of cases. Due to side effects and increasing antifungal resistance presented by standard therapies, phenolic compounds, such as p-coumaric acid (p-CA), have been studied as molecules from natural sources with potential antifungal activity.

Directed Evolution of Unspecific Peroxygenase in Organic Solvents.

Biotechnol Bioeng 2021 May 8. Epub 2021 May 8.

Department of Biocatalysis, Institute of Catalysis, CSIC, Cantoblanco, Madrid, Spain.

Fungal unspecific peroxygenases (UPOs) are efficient biocatalysts that insert oxygen atoms into non-activated C-H bonds with high selectivity. Many oxyfunctionalization reactions catalyzed by UPOs are favored in organic solvents, a milieu in which their enzymatic activity is drastically reduced. Using as departure point the UPO secretion mutant from Agrocybe aegerita (PaDa-I variant), in the current study we have improved its activity in organic solvents by directed evolution. Read More
