The intestine is one of the most important sites for the metabolism of several xenobiotic compounds. In addition to intestinal drug-metabolizing enzymes and drug transporters, gut microbial enzymes modulate the biotransformation of orally administered drugs in the gastrointestinal tract. Antihypertensive drugs such as amlodipine and nifedipine could be metabolized by gut microbial enzymes, which may influence drug absorption, leading to changes in pharmacological potency of the drug and eventual failure of the appropriate blood pressure control or unexpected side effects...

Excess caloric intake and less energy expenditure (eg. physical inactivity) are associated with acquired metabolic disorders due to sedentary life style. Pharmacological treatments are less effective in preventing obesity. Type of diet influence the gut microbiome alteration and it is interrelated with obesity, insulin resistance and type 2 diabetes. Modified gut microbiota by the harmful bacterial components (eg: lipopolysaccharides) is linked with the metabolic endotoxemia (low-grade inflammation) which results in damage to the gut barrier function...

Nonalcoholic fatty liver disease (NAFLD), an increasingly prevalent paediatric disorder, is diagnosed and managed not only by both pediatric gastroenterologists/hepatologists but also frequently by the general pediatrician. This article updates recent advances in diagnostic and therapeutic approach, which may be applied to everyday practice. Diagnosis of NAFLD takes into account the risk factor profile and is a diagnosis of exclusion. Techniques such as transient elastography and specific biomarkers aimed at improving diagnosis and monitoring of NAFLD need further validation in the pediatric population...

BACKGROUND & AIMS: We have previously reported an increased nitrosative stress in the kidneys of diabetic animals, which was reduced by an antioxidant probiotic. The present study evaluated whether the extract of cupuaçu (EC), an antioxidant compound rich in polyphenols and theograndins, when administered at a dose that can be reasonably obtained through daily consumption, could delay the onset of diabetic complications in the kidney. METHODS: Mouse immortalized mesangial cells (MiMC) were placed in medium normal glucose (NG) or high glucose (HG), with or without EC (500, 100, 50 or 10 μg/mL) during 24, 48 or 72 h for analysis of viability, proliferation, nitric oxide (NO) levels and reactive oxygen species or nitrogen (ROS/RNS)...

The main treatment of patients with non-alcoholic fatty liver disease (NAFLD) is life style modification including weight reduction and dietary regimen. Majority of patients are safely treated with this management and pharmacologic interventions are not recommended. However, a subgroup of NAFLD patients with non-alcoholic steatohepatitis (NASH) who cannot achieve goals of life style modification may need pharmacological therapy. One major obstacle is measurement of histological outcome by liver biopsy which is an invasive method and is not recommended routinely in these patients...

Probiotics have been proposed as alternatives to pharmacological products in several medical conditions including the modulation of obesity, which is frequently associated with poor semen quality. However, effects of probiotics on male fertility have been less investigated. This study assessed the effect of Lactobacillus rhamnosus PB01 (DSM-14870) on sperm kinematic parameters in Normal-weight (NW) and diet-induced obese (DIO) models. NW and DIO C57BL/6NTac mice were divided into two subgroups with or without a single daily dose (1x109CFU) of L...

Mood disorders such as depression are among the most prevalent psychiatric disorders in the United States, but they are inadequately treated in a substantial proportion of patients. Accordingly, neuropsychiatric research has pivoted from investigation of monoaminergic mechanisms to exploration of novel mediators, including the role of inflammatory processes. Subsets of mood disorder patients exhibit immune-related abnormalities, including elevated levels of proinflammatory cytokines, monocytes, and neutrophils in the peripheral circulation; dysregulation of neuroglia and blood-brain barrier function; and disruption of gut microbiota...

The intestinal barrier controls the absorption of nutrients and water whilst helping to prevent the entry of toxins and pathogenic micro-organisms from the lumen into the tissues. Deficiencies in the barrier are associated with various gastrointestinal and extra digestive disorders. Areas covered: This review provides an overview of the relationship between increased intestinal permeability and disease, and considers the role of mucosal protectants (mucoprotectants) in restoring normal intestinal barrier function, with a particular focus on diarrheal disorders...

The pathophysiology of atopic dermatitis (AD) is multifactorial and is a complex interrelationship between skin barrier, genetic predisposition, immunologic development, skin microbiome, environmental, nutritional, pharmacological, and psychological factors. Several microbial modulations of the intestinal microbiome with pre- and/or probiotics have been used in AD management, with different clinical out-come (both positive, as well as null findings). This review provides an overview of the clinical evidence from trials in children from 2008 to 2017, aiming to evaluate the effect of dietary interventions with pre- and/or pro-biotics for the treatment of AD...

Regulating fluctuating endogenous nitric oxide (NO) levels is necessary for proper physiological functions. Aberrant NO pathways are implicated in a number of neurological disorders, including Alzheimer's disease (AD) and Parkinson's disease. The mechanism of NO in oxidative and nitrosative stress with pathological consequences involves reactions with reactive oxygen species (e.g., superoxide) to form the highly reactive peroxynitrite, hydrogen peroxide, hypochloride ions and hydroxyl radical. NO levels are typically regulated by endogenous nitric oxide synthases (NOS), and inflammatory iNOS is implicated in the pathogenesis of neurodegenerative diseases, in which elevated NO mediates axonal degeneration and activates cyclooxygenases to provoke neuroinflammation...
