nematodes influence microbiome and metabolome characteristics of their natural apple substrates over time.

The microbiomes of host organisms and their direct source environments are closely linked and key for shaping microbial community dynamics. The relationship between these linked dynamics is largely unexplored because source substrates are usually unavailable. To address this current knowledge gap, we employed bacteriovorous nematodes as a unique model system, for which source substrates like rotting apples can be easily collected.

Nutritional Composition and Odor-Contributing Volatile Compounds of the Edible Mushroom .

Chanterelles are one of the most highly valued wild edible mushroom genera worldwide. This work aimed to investigate the nutritional characteristics and volatile compounds' profile of for the first time. Proximate analysis was performed according to the Association of Official Agricultural Chemists, while the mineral contents and the volatile compounds were determined using ICP-MS and GC-MS, respectively.

Live bedside music for hospitalized older adults: A qualitative descriptive interview study.

Introduction: Hospitalization may have a major impact on older patients as it is often a period of psychosocial vulnerability. Music is one of the most described art forms used in healthcare. Applied in clinical settings, it can affect a patients' emotional and psychosocial well-being.

Phytochemical Profile of (Blue Fenugreek) Herb and Quantification of Aroma-Determining Constituents.

The herb of (Fabaceae), commonly known as blue fenugreek, is used for the production of traditional cheese and bread varieties in the Alpine region. Despite its frequent consumption, only one study so far has focused on the constituent pattern of blue fenugreek, revealing qualitative information on some flavor-determining constituents. However, with regard to the volatile constituents present in the herb, the applied methods were insufficient and did not take relevant terpenoids into account.

The long road of functional recruitment-The evolution of a gene duplicate to pyrrolizidine alkaloid biosynthesis in the morning glories (Convolvulaceae).

In plants, homospermidine synthase (HSS) is a pathway-specific enzyme initiating the biosynthesis of pyrrolizidine alkaloids (PAs), which function as a chemical defense against herbivores. In PA-producing Convolvulaceae ("morning glories"), HSS originated from deoxyhypusine synthase at least >50 to 75 million years ago via a gene duplication event and subsequent functional diversification. To study the recruitment of this ancient gene duplicate to PA biosynthesis, the presence of putative gene copies in 11 Convolvulaceae species was analyzed.
