Identification of 2,4-Di--Butylphenol as an Antimicrobial Agent Against Bacteria from Rwandan Propolis.

Background/objectives: Acne is the most prevalent dermatological condition among humans, affecting approximately 80% of adolescents during puberty. To date, numerous compounds have been used for acne treatment, including erythromycin ointments and antiseptics, with varying degrees of success. The emergence of erythromycin-resistant strains has spurred the search for new antimicrobial agents, particularly from natural sources.

Synthesis and Antibacterial Activity of Alkylamine-Linked Pleuromutilin Derivatives.

In an effort to expand the spectrum of the antibacterial activity of pleuromutilin, a series of amine- and polyamine-linked analogues were prepared and evaluated for activities against a panel of microorganisms. Simple C-22-substituted amino esters or diamines , , , and , as well as two unusual amine-linked bis-pleuromutilin examples and , displayed variable levels of activity towards ATCC 25923 and methicillin-resistant , but with no detectable activities towards Gram-negative bacteria. Fortunately, the incorporation of a longer-chain triamine or polyamine (spermine) at C-22 did afford analogues (, ) that exhibited activity towards both ATCC 25923 and ATCC 25922 with MIC 6.

HERV-W ENV transcription in B cells predicting symptomatic COVID-19 and risk for long COVID can express a full-length protein despite stop codon in mRNA from chromosome X via a ribosome readthrough.

The human genome comprises 8 % of endogenous retroviruses (HERVs). Though HERVS contribute to physiological functions, copies retained pathogenic potential. The HERV-W ENV protein was shown expressed in patients with worse COVID-19 symptoms and post-COVID syndrome.

Inhibition in the emotional Hayling task: can hypnotic suggestion enhance cognitive control on a prepotent negative word?

Recent studies suggest that instrumental hypnosis is a useful experimental tool to investigate emotional and language processing effects. However, the capacity of hypnotic suggestions to intervene during the response inhibition of emotional words remains elusive. This study investigated whether hypnotic suggestion can improve the inhibition of prepotent negative word responses in an emotional Hayling sentence completion task.

French Norms for a Shortened Online Adaptation of the Harvard Group Scale of Hypnotic Susceptibility, Form A.

This study presents the norms and psychometric properties for a shortened online adaptation of a French version of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A). Assessment of involuntariness and subjective intensity was added to the traditional scoring. A total of 373 individuals completed an online hypnotizability screening test on their own computer.
