Role of biocontrol yeasts Debaryomyces hansenii and Wickerhamomyces anomalus in plants' defence mechanisms against Monilinia fructicola in apple fruits.

Role of biocontrol yeasts Debaryomyces hansenii and Wickerhamomyces anomalus in plants' defence mechanisms against Monilinia fructicola in apple fruits. Food Microbiol. 2019 Oct;83:1-8 Authors: Czarnecka M, Żarowska B, Połomska X, Restuccia C, Cirvilleri G Abstract The role of killer yeasts of the species Debaryomyces hansenii and Wickerhamomyces anomalus in biocontrol of Monilinia fructicola, and their involvement in plant defence mechanisms against brown rot in apple fruits, were investigated. D. hansenii KI2a and W. anomalus BS91 strains showed the highest in vitro biocontrol activity, inhibiting mycelium growth by 69.53% and 66.08% respectively, as compared to control fungal cultures. Brown rot on apple fruits was significantly reduced by BS91 and two strains of D. hansenii KI2a and AII4b by 92.46%, 85.10% and 70.02%, respectively, in comparison to infected fruits, which did not receive any pre-treatment. In enzymatic tests, the most significant changes in peroxidase (POD) and catalase (CAT) activities were observed in fruits inoculated either with BS91 followed by M. fructicola infection or with AII4b yeast strain alone, where POD activities were significantly higher by 67% and 54%, respectively, and CAT activities were significantly lower by 65% and 68%, respectively, than in untreated control fruits. These results confirmed the ability of killer yeasts to influence host-defence related enzyme activities in apple fruit tissue and may suggest that...

Conclusion: Results suggest that T20 has a double-target mechanism, by which its N-terminal and C-terminal portions bind to N-terminal heptad repeat and FPPR, respectively. T20-SF designed based on this new mechanism exhibits significantly improved anti-HIV-1 activity because it targets the triple sites in gp41, including N-terminal heptad repeat, FPPR, and fusion peptide. Thus, this study provides clues for designing novel HIV fusion inhibitors with improved antiviral activity.

Conclusion: These results indicate that Tg26+/−/ApoE−/− serve as a new mouse model for HIV-induced atherogenesis, and aid in understanding the role of tryptophan catabolism in the pathogenesis of HIV atherosclerosis/CVD.

Conclusion: Our data explore the hypothesis that poorly recognized epitope variants not only facilitate HIV-1 evasion of CTL recognition, but also induce CTL dysfunction through suboptimal signaling causing anergy. However, the results do not suggest that suboptimal signaling induces anergy (or exhaustion or apoptosis), indicating that the major role of CTL epitope variation is likely viral escape.

Background: Many of those aging with HIV suffer from distal neuropathic pain (DNP) due to HIV-associated sensory neuropathy (HIV-SN). Prior studies have linked chronic pain conditions to a variant of the catechol-O-methyltransferase (COMT), Val158Met. This variant confers reduced enzymatic activity and results in higher synaptic dopamine levels. Here we examined the role of Val158Met as a predictor of DNP in HIV-SN. Methods: In 1044 HIV-infected individuals enrolled in CNS HIV Antiretroviral Therapy Effects Research, an observational study across six US institutions, we characterized the relationship between Val158Met...

Conclusion: Switching to E/C/F/TAF was noninferior to continuing ABC/3TC plus a third agent for maintenance of HIV RNA suppression at Week 24. This study supports E/C/F/TAF as an efficacious and well tolerated option for participants switching from ABC/3TC-based regimens.

Conclusion: ART-naive Ethiopian HIV patients had a high prevalence of prediabetes and diabetes, with a poor agreement between HbA1c and OGTT. Diabetes was associated with inflammation, but not with adiposity and age. Diabetes was linked to insulin deficiency, rather than insulin resistance, which may represent a different entity than type 1 and 2 diabetes. This has implications for choice of drugs, when managing diabetes in African HIV patients.

Conclusion: Neuropsychiatric illness increased odds of being frail on a predominantly physical/motoric measure, but only when symptomatic. Lack of association with asymptomatic impairment may reflect the importance of functional limitation to frailty, or possibly a unique resilience phenotype. Understanding why sex and symptomatic neuropsychiatric illness are associated with frailty will be important in managing HIV-associated morbidity in aging populations.

Conclusion: E157Q substitution, reducing raltegravir and elvitegravir activity, was frequently found in acute/recent HIV cases. All cases were infected with subtype B, and some were included in clusters. Cases treated with dolutegravir-based regimens had good virological response.

Conclusion: Among women at risk of HIV-1 infections in South Africa, we found no statistically significant differences in HIV-1 incidence by contraceptive method. Implants had the lowest point estimate for HIV-1 incidence, and IUDs had risk comparable with injectable methods in multivariate models. Large, prospective studies are needed to define better the relative HIV-1 risks across different contraceptive methods.

Conclusion: Despite high ART coverage, good maternal health and very low vertical HIV transmission rate, maternal HIV infection remained associated with increased risk of adverse perinatal outcomes. Larger studies using first trimester ultrasound for pregnancy dating are needed to further assess associations with specific adverse perinatal outcomes.
