It is becoming increasingly clear that commensal bacteria inhabiting our body surfaces interact closely with the host to modulate a vast number of physiological functions. Metabolism of dietary components by gut microbiota can result in formation of a variety of reactive compounds associated with both favorable and unfavorable health effects. N-nitrosamines and trimethylamine-N-oxide (TMAO) have been associated with detrimental health effects, including increased risk of cardiovascular and metabolic disease. Contrary, bacteria-dependent formation of nitric oxide and related bioactive nitrogen oxides from dietary nitrate have been associated with salutary effects on cardiovascular function, metabolic control and more. Here we briefly discuss how the microbiota interacts with dietary factors to regulate host functions in health and disease, focusing on formation of reactive nitrogen compounds.

Neurodegenerative diseases are significant health concerns that have a profound impact on the quality and duration of life for millions of individuals. These diseases are characterized by pathological changes in various brain regions, specific genetic mutations associated with the disease, deposits of abnormal proteins, and the degeneration of neurological cells. As neurodegenerative disorders vary in their epidemiological characteristics and vulnerability of neurons, treatment of these diseases is usually aimed at slowing disease progression.

We analyze the proteome changes during the development of the carnauba palm (Copernicia prunifera) seedlings under skotomorphogenic conditions, by separating the embryo into its two components: haustorium (HA) and cotyledonary petiole (CP) and established the descriptive and quantitative proteomes of these tissues across four developmental stages. 5205 proteins were identified in HA and 6028 in CP. These proteomes are rich in proteins known to maintain the skotomorphogenic state, and in a complete set of proteins involved in cellular respiration and biosynthesis of secondary metabolites.

Nitrogen fixation is essential for the sustainable development of both human society and the environment. Due to the chemical inertness of the N≡N bond, the traditional Haber-Bosch process operates under extreme conditions, making nitrogen fixation under ambient conditions highly desirable but challenging. In this study, we present an ultrasonic atomizing microdroplet method that achieves nitrogen fixation using water and air under ambient conditions in a rationally designed sealed device, without the need for any catalyst.

Aortic valve calcification results from degenerative processes associated with several pathologies. These processes are influenced by age, chronic inflammation, and high concentrations of phosphate ions in the plasma, which contribute to induce mineralization in the aortic valve and deterioration of cardiovascular health. Environmental factors, such as wood smoke that emits harmful and carcinogenic pollutants, carbon monoxide (CO), and nitrogen oxide (NO), as well as other reactive compounds may also be implicated.

The objective of the present work was to examine the effect of incorporating spirulina powder (SP) in -type sausages made exclusively with camel meat, as well as to evaluate its physicochemical, microbiological, and sensory quality attributes and its prebiotic potential. The final purpose was to offer an innovative meat product to increase camel meat consumption. Several innovative fresh sausage formulations were developed using SP (00, 100, 250, and 500 mg/kg) and stored under vacuum conditions with refrigeration at 1 ± 1 °C for 35 days.
