Microbially-Induced Desaturation and Carbonate Precipitation
Microbially induced carbonate precipitation (MICP) has been proposed as a sustainable approach to solve various environmental, structural, geotechnical and architectural issues. In the last decade, a ubiquitous microbial metabolism, nitrate reduction (also known as denitrification) got attention in MICP research due to its unique added benefits such as simultaneous corrosion inhibition in concrete and desaturation of porous media. The latter even upgraded MICP into a more advanced concept called microbially induced desaturation and precipitation (MIDP) which is being investigated for liquefaction mitigation.

TPC1 in plants
TPC1 in plants is localized in the vacuolar membrane. Its activity is strictly regulated by several factors emphasizing its complex structure and function. The physiological role of TPC1 is under debate. The TPC1 hyperactive version fou2 (carring D454N mutation) is characterized by an overproduction of jasmonate acid (JA), however the tpc1-2 knockout mutant has no pronounced phenotype. The intriguing concept of Ca2+-induced Ca2+ release was assigned to Vicia faba TPC1 in 1994 by Ward and Schroeder, however it has still not been confirmed for the model plant Arabidopsis thaliana.

The ABC Model of Happiness
Happiness is a feeling, an immediate experience, not a cognitive construct. It is based on activity in the brain’s neurobiological reward and motivation systems, which have been retained in evolution.

Anne Treisman
Anne Marie Treisman (née Taylor; 27 February 1935[1] – 9 February 2018)[2][3][4] was an English psychologist who specialised in cognitive psychology. Treisman researched visual attention, object perception, and memory. One of her most influential ideas is the feature integration theory of attention, first published with Garry Gelade in 1980. Treisman taught at the University of Oxford, Unive

Sulfate Reduction in Intestinal Bacteria
Sulfate is present in foods, beverages, and drinking water. Its reduction and concentration in the gut depend on the intestinal microbiome activity, especially sulfate-reducing bacteria (SRB), which can be involved in inflammatory bowel disease (IBD). Assimilatory sulfate reduction (ASR) is present in all living organisms. In this process, sulfate is reduced to hydrogen sulfide and then included in cysteine and methionine biosynthesis. In contrast to assimilatory sulfate reduction, the dissimilatory process is typical for SRB. A terminal product of this metabolism pathway is hydrogen sulfide, which can be involved in gut inflammation and also causes problems in industries (due to corrosion effects).

Hydrogen Sulfide
Hydrogen sulfide is a colorless gas with a characteristic smell like rotten eggs. It is flammable and corrosive at very high concentrations. It has been always considered a toxic molecule, but more recently, it has been proved it is a metabolite and signaling molecule in biological tissues that regulates many physiological processes.

Dysregulation of Microbiome–Immunity Interaction in Various Diseases
Gut microbes and their metabolites are actively involved in the development and regulation of host immunity, which can influence disease susceptibility. The role of the microbiome as a protective force is supported by research indicating that immature microbiomes of neonates are more susceptible to invasion by pathobionts. During early years of development, exposure to various microbes shapes the immune system for a lifetime. The gut microbiome has a wide range of metabolic activities, including metabolizing lipids, carbohydrates, and proteins, and participates in maintaining host homeostasis. Therefore, disruption of gut microbiome can lead to conditions as severe as cancer.

Epigenetics and Probiotics Application in Fish Reproductive Performance
Fish represent an excellent source of animal protein as well as a biomedical research model as a result of their evolutionary relatedness and similarity with the human genome. Commercial and ornamental fish culture has achieved popularity, but reproductive dysfunctions act as a limiting factor for quality fry production, interfering with the sustainability of the aquaculture industry. Fish reproduction is crucial for any species’ existence, and reproductive performance can potentially be improved through applications of epigenetics and probiotics. Epigenetics is a highly sensitive molecular approach that includes chromatin structure and function alteration, DNA methylation, and modification of non-coding RNA molecules for the transfer of desired information from parents to offspring. DNA methyltransferase improves reproductive cyp11a1, esr2b, and figla gene expression and feminizes zebrafish (Danio rerio). Moreover, epigenetics also contributes to genome stability, environmental plasticity, and embryonic development. However, methylation of specific genes can negatively affect sperm quality, resulting in poor fertilization. Probiotic administration is able to induce responsiveness of incompetent follicles to maturation-inducing hormones and can change oocyte chemical composition during vitellogenic development. The positive role of probiotics on testicular cells is validated by upregulating the transcription levels of leptin, bdnf, and dmrt1 genes facilitating the spermatogenesis.
