Gut Microbiota in Anxiety and Depression
The gut microbiota is critical for maintaining human health and the immunological system. Several neuroscientific studies have shown the significance of microbiota in developing brain systems. The gut microbiota and the brain are interconnected in a bidirectional relationship, as research on the microbiome–gut–brain axis shows. Significant evidence links anxiety and depression disorders to the community of microbes that live in the gastrointestinal system. Modified diet, fish and omega-3 fatty acid intake, macro- and micro-nutrient intake, prebiotics, probiotics, synbiotics, postbiotics, fecal microbiota transplantation, and 5-HTP regulation may all be utilized to alter the gut microbiota as a treatment approach.

Gut Microbiota in Psychiatric Disorders
The importance of the gut–brain axis in maintaining homeostasis has long been appreciated. Much recent work has implicated the gut microbiota in many conditions, including autism, anxiety, obesity, schizophrenia, Parkinson’s disease, and Alzheimer’s disease. Increased Enterobacteriaceae family were potentially associated with a higher risk of schizophrenia; thus, keeping these types of bacteria in balance will help alleviate the adverse effects of other pathogenic bacteria that might cause several diseases. According to the growing body of research, the gut microbiota is becoming crucial in psychiatric disorders.

Gut Microbiota Modulation in Cardiometabolic Diseases Treatment
The diverse relationship between cardiometabolic diseases (CMD) vulnerability and changes in gut microbiota make-up and metabolites has emphasized that gut microbiota is an unfamiliar modulator of CMD. These connections are possible targets for new CMD therapy. The host–microbiota interaction is made up of various levels at which potential therapeutic interventions can be instituted. These levels include dietary substrates, microbial ecology, and microbiota–host pathways that liberate metabolites that modulate host processes. Agents that inhibit recognized gut microbial enzymes can also be produced. The interesting part of this is that interventions directed at gut microbiota and/or their metabolism in lieu of the host may not necessarily be taken up into the host circulation, hence minimizing the likely adverse effects in comparison to those directed at host metabolism. Among the challenges of therapeutically targeting the gut microbiota are the individual variations, in addition to differences, in gut microbiota make-up, which can affect the action of the medication. This may call for individualized treatment. The gut-microbiota-directed therapeutic concept is based on targeting microbiota compositions, metabolic pathways, and mucosal barrier protection.

Gut-Derived Protein-Bound Uremic Toxins
Chronic kidney disease (CKD) afflicts more than 500 million people worldwide and is one of the fastest growing global causes of mortality. When glomerular filtration rate begins to fall, uremic toxins accumulate in the serum and significantly increase the risk of death from cardiovascular disease and other causes. Several of the most harmful uremic toxins are produced by the gut microbiota. Furthermore, many such toxins are protein-bound and are therefore recalcitrant to removal by dialysis. We review the derivation and pathological mechanisms of gut-derived, protein-bound uremic toxins (PBUTs). We further outline the emerging relationship between kidney disease and gut dysbiosis, including the bacterial taxa altered, the regulation of microbial uremic toxin-producing genes, and their downstream physiological and neurological consequences. Finally, we discuss gut-targeted therapeutic strategies employed to reduce PBUTs. We conclude that targeting the gut microbiota is a promising approach for the treatment of CKD by blocking the serum accumulation of PBUTs that cannot be eliminated by dialysis.

Health-Promoting Effect of Lycopene
Lycopene is a compound of colored origin that shows strong antioxidant activity. The positive effect of lycopene is the result of its pleiotropic effect. The ability to neutralize free radicals via lycopene is one of the foundations of its pro-health effect, including the ability to inhibit the development of many civilization diseases.

Heavy Metals Levels in Adolescents
In the Milazzo-Valle del Mela area, the presence of industrial plants and the oil refinery make local residents concerned for their health. For this reason, we evaluated the levels of heavy metals in 226 children aged 12–14 years, living in the 7 municipalities of the area. A control age-matched population (n = 29) living 45 km far from the industrial site was also enrolled. Arsenic, cadmium, chromium, mercury, nickel, and vanadium were analysed in 24 h urine samples, while lead concentration was evaluated in blood samples. A questionnaire regarding life style and risk perception was also administered. Adolescents from Milazzo-Valle del Mela had cadmium levels significantly higher compared to either controls (P < 0.0001) or the reference values of the European Germany Environmental Survey (GerES-IV) and the American National Health and Nutrition Examination Survey (NHANES). Furthermore, children had higher perception of living in a high-risk environment. The present data, for the first time, clearly indicate that adolescents living in Milazzo-Valle del Mela have increased body concentration of cadmium, which may be harmful to human health. These results deserve particular attention by the local and regional government to initiate prevention programmes in this susceptible population.

Hemorphins
Hemorphins are endogenous peptides that are also known as “non-classical” or “atypical” opioid peptides. They are produced under physiologicalor pathological(inflammation) states by hemoglobin proteolysis. They can be released from almost any of the hemoglobin chains (beta-, kappa-, delta-, or epsilon-chain) except the alpha chain.

Hepatic CYP2E1 in Causal Toxicity and Treatment Options
Cytochrome P450 2E1 (CYP2E1), one of the major metabolizing enzymes in humans, is mainly expressed in the liver. Alcohol and several therapeutic drugs, including acetaminophen, are metabolized by CYP2E1 into toxic compounds. At low levels, these compounds are not detrimental, but higher sustained levels of these compounds can lead to life-long problems such as cytotoxicity, organ damage, and cancer. Furthermore, CYP2E1 can facilitate or enhance the effects of alcohol-drug and drug-drug interactions.

Herbal Treatments for Breast Cancer
Breast cancer is a complex disease for which pharmacological treatment does not guarantee success or cure. Plants possess phytochemical components with antioxidant and anti-inflammatory properties, mainly coumarins, flavonoids, alkaloids, and terpenoids. Several studies have demonstrated that bioactive compounds from plants can exert anti-tumor activity through various signaling pathways, such as apoptosis, autophagy, modification of the tumor microenvironment, cell arrest, and the suppression of angiogenesis.
