The essential oils were also tested for their antioxidant, anti-imflammatory, antimicrobial and cytotoxic activities. The HD essential oil sample showed inhibitory activity against 6/8 tested microorganisms, i.e., Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus subtillis, Candida albicans, and Saccharomyces cerevisiae. The MHD and EHD exhibited the inhibitory activity against three strains E. coli, A. niger and F. oxysporum. The UHD inhibited E. coli and F. oxysporum.

Ebook "Surface analysis and techniques in biology" summarizes the main surface analysis techniques that are being used to study biological specimens/systems. The compilation of chapters in this book highlight the benefits that surface analysis provides. The outer layer of bulk solid or liquid samples is referred to as the surface of the sample/material. At the surface, the composition, microstructure, phase, chemical bonding, electronic states, and/or texture is often different than that of the bulk material.

Epigenetic clocks can track both chronological age (cAge) and biological age (bAge). The latter is typically defined by physiological biomarkers and risk of adverse health outcomes, including all-cause mortality. As cohort sample sizes increase, estimates of cAge and bAge become more precise. Here, we aim to develop accurate epigenetic predictors of cAge and bAge, whilst improving our understanding of their epigenomic architecture.

Ebook "Peptidomics: Methods and strategies" describes protocols for basic state-of-the-art approaches in the field of peptidomics. Most of these approaches are independent of the instruments used for analysis and can easily be adapted for equipment that is available in a typical proteomics facility. Chapters detail many of the basic techniques used to detect and identify peptides, methods for the relative quantitation of peptides between samples using isotopic labels or label-free approaches, and biological species as well as sample types.
