Comparative transcriptional analysis of biofilms following farnesol and tyrosol treatment.

Unlabelled: is frequently associated with biofilm-related invasive infections. The resistant profile of these biofilms necessitates innovative therapeutic options, where quorum sensing may be a potential target. Farnesol and tyrosol are two fungal quorum-sensing molecules with antifungal effects at supraphysiological concentrations.

Total transcriptome analysis of Candida auris planktonic cells exposed to tyrosol.

Tyrosol, a secondary metabolite of Candida species, regulates fungal morphogenesis, and its application may represent a novel innovative therapy against emerging multi-resistant fungal superbug such as Candida auris. In the current study, the effects of tyrosol on growth, redox homeostasis, intracellular microelement contents and activities of virulence-related enzymes released by C. auris were examined.

First Synthesis of DBU-Conjugated Cationic Carbohydrate Derivatives and Investigation of Their Antibacterial and Antifungal Activity.

The emergence of drug-resistant bacteria and fungi represents a serious health problem worldwide. It has long been known that cationic compounds can inhibit the growth of bacteria and fungi by disrupting the cell membrane. The advantage of using such cationic compounds is that the microorganisms would not become resistant to cationic agents, since this type of adaptation would mean significantly altering the structure of their cell walls.

Concentration-Dependent Antibacterial Activity of Chitosan on .

The antimicrobial effect of chitosan and synthetic chitosan derivatives has been confirmed on many Gram-positive and Gram-negative bacteria and fungi. The tests were carried out on pathogenic microorganisms, so the mechanism and concentration dependence of the inhibitory effect of chitosan were revealed. We conducted our tests on a probiotic strain, .

Physiological and transcriptional profiling of surfactin exerted antifungal effect against Candida albicans.

Given the risk of Candida albicans overgrowth in the gut, novel complementary therapies should be developed to reduce fungal dominancy. This study highlights the antifungal characteristics of a Bacillus subtilis-derived secondary metabolite, surfactin with high potential against C. albicans.

[Clinical and epidemiological characteristics of pediatric COVID-19 patients in a community-based study].

Unlabelled: Összefoglaló. Bevezetés: A COVID-19-pandémia kapcsán számos tanulmány vizsgálta a tünetek gyakoriságát és a járványterjedés jellemzőit gyermekkorban, kevés azonban az alapellátás adatait összefoglaló publikáció. Közleményünkben 12 házi gyermekorvosi praxis 545 SARS-CoV-2-fertőzött betegének adatait elemeztük a 2.

Transcriptional Profiling of the Candida auris Response to Exogenous Farnesol Exposure.

The antifungal resistance threat posed by Candida auris necessitates bold and innovative therapeutic options. Farnesol is a quorum-sensing molecule with a potential antifungal and/or adjuvant effect; it may be a promising candidate in alternative treatment regimens. To gain further insights into the farnesol-related effect on C.

Transcriptional control of transglutaminase 2 expression in mouse apoptotic thymocytes.

Transglutaminase 2 (TGM2) is a ubiquitously expressed multifunctional protein, which participates in various biological processes including thymocyte apoptosis. As a result, the transcriptional regulation of the gene is complex and must depend on the cell type. Previous studies from our laboratory have shown that in dying thymocytes the expression of Tgm2 is induced by external signals derived from engulfing macrophages, such as retinoids, transforming growth factor (TGF)-β and adenosine, the latter triggering the adenylate cyclase signaling pathway.
